Section 1 Fund Summaries

Nuveen ESG Dividend ETF

Investment Objective

Nuveen ESG Dividend ETF (the “Fund”) seeks to track the investment results, before fees and expenses, of the TIAA ESG USA High Dividend Yield Index (the “Index”).

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, when buying or selling shares of the Fund, which are not reflected in this table or the example that follows:

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)


Management Fees	0.25%
Distribution and/or Service (12b-1) Fees	None
Other Expenses	0.01%
Total Annual Fund Operating Expenses	0.26%

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example does not reflect brokerage commissions that you may pay when you purchase and sell Fund shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


1 Year	$27
3 Years	$84
5 Years	$146
10 Years	$331

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 76% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the Index, which is comprised of high dividend paying equity securities issued by companies listed on U.S. exchanges that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects securities that exhibit high dividend income and quality characteristics, including companies that have higher than average dividend yields that are both sustainable and persistent, from the MSCI USA Index (the “Base Index”). The Base Index generally consists of the large- and mid-capitalization segments of the U.S. market. MSCI Inc. (“MSCI”) is the index provider for the Index and the Base Index. The Index and the Base Index are owned, calculated and controlled by MSCI, in its sole discretion. MSCI is not affiliated with the Fund, its investment adviser or sub-adviser. None of the Fund’s investment adviser, sub-adviser, or their affiliates has any discretion to select Index components or change the Index methodology.

assessment categories can include how a company is addressing climate change, natural resource use, and waste management and emission management. Social evaluation categories can include a company’s relations with employees and suppliers, product safety and sourcing practices. Governance assessment categories can include governance practices and business ethics. The ESG criteria also consider how well a company adheres to national and international laws and regulations related to ESG matters. Index rules exclude companies with significant activities in the following controversial businesses: alcohol production, tobacco production, nuclear power, gambling, and weapons and firearm production. Companies otherwise eligible for inclusion in the Index that exceed certain carbon-based ownership and emissions thresholds are excluded from the Index.

Companies that are not excluded by the ESG criteria are then ranked within their respective sectors based on their ESG performance scores. The highest ranked companies in each sector are identified as eligible for inclusion in the Index until such point that the aggregate weight of companies in the sector reaches 50% of the market cap of such sector in the Base Index. For example, if the market capitalization of all consumer discretionary sector companies included in the Base Index totals $200 billion, then the Index would screen these consumer discretionary sector companies, rank them based on ESG performance scores, and add the highest scoring companies to the Index until such point that their combined total market capitalization reaches $100 billion. Those companies identified as eligible for inclusion in the Index are market capitalization weighted within their respective sectors. Once the universe of eligible Index components is established, the Index optimizes the market cap weightings of its individual components so that the sector weightings of the Index approximate the sector weightings of the Base Index, within certain constraints established by the Index. As of the date of this prospectus, a significant portion of the Index is comprised of companies in the industrials and financial services sectors.

In seeking to track the investment results of the Index, the Fund attempts to replicate the Index by investing all, or substantially all, of its assets in the securities represented in the Index in approximately the same proportions as the Index. The Index is normally rebalanced and reconstituted quarterly in February, May, August, and November. The Index may also remove a security at any time in response to a corporate event such as bankruptcy, delisting, merger or acquisition that causes the security to become ineligible for inclusion in the Index. The Fund makes changes to its portfolio shortly after any Index changes are made public. As of December 31, 2022, the Index was comprised of 624 securities.

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the Index. To the extent the Index concentrates (i.e., holds 25% or more of its total assets) in the securities of companies in a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the Index.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

Concentration Risk—To the extent that the Fund’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries or sector, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries or sector.

Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider or a financial intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Dividend-Paying Security Risk—The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce


Section 1 Fund Summary	3

or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time.

ESG Strategy Risk—Because the Fund’s ESG investment strategy will exclude securities of certain issuers for non-financial reasons based on the ESG criteria of the Index (i.e., companies that do not demonstrate sustainable ESG characteristics or are involved in certain prohibited activities), the Fund may forgo some market opportunities available to funds that do not use an ESG investment strategy or may be required to sell a security when it might otherwise be disadvantageous to do so. This may cause the Fund to underperform the stock market as a whole or other funds that do not use an ESG investment strategy. In addition, there is a risk that the companies identified by the Fund’s ESG investment strategy will not operate as expected when addressing ESG issues or they will not exhibit positive ESG characteristics as intended. There are also significant differences in interpretations of what it means for a company to have positive ESG characteristics. As a result, the factors and criteria considered when generating ESG data and the results of such ESG research generally differ across ESG data providers. Further, in selecting companies for inclusion in the Index, the index provider relies on information and ESG performance data from an affiliated research provider, which could be incomplete or erroneous, which in turn could cause the index provider to assess a company’s ESG characteristics incorrectly. Furthermore, because ESG considerations are still an emerging area of investment focus, data availability and reporting with respect to ESG criteria may not always be available or may become unreliable.

Financial Services Sector Risk—The Fund currently invests a significant portion of its assets in the financial services sector, although this may change over time. Financial services companies are particularly sensitive to the adverse effects of economic recession; changes in government regulation; the availability of capital; volatile interest rates; and the health of the commercial and residential real estate markets.

Index Provider Risk—There is no assurance that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, an index provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the Fund’s costs. Unusual market conditions may cause an index provider to postpone a scheduled rebalance. Such a postponement in a time of market volatility could mean a constituent that would otherwise be removed at rebalance may remain, causing the performance and constituents of the index to vary from those expected under normal conditions. Index providers generally do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the indexes in which they license, and generally do not guarantee that an index will be calculated in accordance with its stated methodology. Losses or costs associated with any index provider errors generally will be borne by the Fund and its shareholders.

Industrials Sector Risk—The Fund currently invests a significant portion of its assets in the industrials sector, although this may change over time. Industrials companies are affected by various factors, including the general state of the economy, exchange rates, commodity prices, intense competition, consolidation, domestic and international politics, government regulation, import controls, excess capacity, consumer demand and spending trends. In addition, industrials companies may also be significantly affected by overall capital spending levels, economic cycles, rapid technological changes, delays in modernization, labor relations, environmental liabilities, governmental and product liability and e-commerce initiatives.

Investment Style Risk—The Fund invests in the securities included in, or representative of, the Index regardless of their investment merit. The Fund does not attempt to outperform the Index or take defensive positions in declining markets or in response to changing market conditions. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to the Index. In addition, because the Index selects securities for inclusion based on ESG criteria, the Fund may forgo some market opportunities available to funds that do not use these criteria.

Large-Cap Company Risk—Because it invests primarily in securities of large-capitalization companies, the Fund may underperform funds that invest primarily in securities of smaller capitalization companies during periods when the securities of such companies are in favor.

will approximate its net asset value (“NAV”), there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy Fund shares on the secondary market, and you may receive more or less than NAV when you sell those shares. Although the Fund’s shares are listed for trading on a national securities exchange, it is possible that an active trading market may not develop or be maintained, in which case transactions may occur at wider bid/ask spreads (which may be especially pronounced for smaller funds). Trading of the Fund’s shares may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). In times of market stress, the Fund’s underlying portfolio holdings may become less liquid, which in turn may affect the liquidity of the Fund’s shares and/or lead to more significant differences between the Fund’s market price and its NAV. Market makers are under no obligation to make a market in the Fund’s shares, and authorized participants are not obligated to submit purchase or redemption orders for the Fund’s shares. In the event market makers cease making a market in the Fund’s shares or authorized participants stop submitting creation or redemption orders, Fund shares may trade at a larger premium or discount to NAV.

Mid-Cap Company Risk—Securities of mid-cap companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or broader market averages in general.

Service Provider Operational Risk—The Fund’s service providers, such as the Fund’s administrator, custodian or transfer agent, may experience disruptions or operating errors that could negatively impact the Fund. Although service providers are required to have appropriate operational risk management policies and procedures, and to take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors, it may not be possible to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Tracking Error Risk—Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of, for example, pricing differences, transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of distributions, changes to the Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, but the Index does not.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. Both the bar chart and the table assume that all distributions have been reinvested. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/etf or by calling (800) 257-8787.

During the period reflected in the bar chart above, the Fund’s highest and lowest quarterly returns were 14.36% and -10.72%, respectively, for the quarters ended December 31, 2022 and June 30, 2022.


Section 1 Fund Summary	5

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and the Index. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Purchase and Sale of Fund Shares

The Fund is an ETF. Shares of the Fund are listed on a national securities exchange and can only be bought and sold in the secondary market through a broker-dealer at market prices. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (at a “premium”) or less than NAV (at a “discount”). An investor may also incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund shares (bid) and the lowest price a seller is willing to accept for Fund shares (ask) when buying and selling shares in the secondary market (the “bid/ask spread”). Recent information regarding the Fund, including its NAV, market price, premiums and discounts, and bid/ask spreads, is available on the Fund’s website at www.nuveen.com/etf.

Tax Information

The Fund’s distributions are taxable and will generally be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred account, such as an individual retirement account (“IRA”) or 401(k) plan (in which case you may be taxed upon withdrawal of your investment from such account).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund’s investment adviser or its affiliates may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

The Fund seeks to track the investment results of the Index, which is comprised of equity securities issued by large capitalization companies listed on U.S. exchanges that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects from the securities included in the MSCI USA Index (the “Base Index”), which generally consists of the large-and mid-capitalization segments of the U.S. market. Securities in the Base Index are weighted based on market capitalization. MSCI Inc. (“MSCI”) is the index provider for the Index and the Base Index. The Index and the Base Index are owned, calculated and controlled by MSCI, in its sole discretion. Neither the Fund’s investment adviser, sub-adviser, nor their affiliates has any discretion to select Index components or change the Index methodology.

The Index identifies equity securities from the Base Index that satisfy certain ESG criteria, based on ESG performance data collected by MSCI ESG Research, Inc., an affiliate of the index provider. ESG performance is measured on an industry-specific basis, with assessment categories varying by industry. Companies are scored and ranked against industry peers using a consistent set of key performance indicators to determine relative ESG strength. Environmental assessment categories can include how a company is addressing climate change, natural resource use, and waste management and emission management. Social evaluation categories can include a company’s relations with employees and suppliers, product safety and sourcing practices. Governance assessment categories can include governance practices and business ethics. The ESG criteria also consider how well a company adheres to national and international laws and regulations related to ESG matters. Index rules exclude companies with significant activities in the following controversial businesses: alcohol production, tobacco production, nuclear power, gambling, and weapons and firearm

Companies that are not excluded by the ESG criteria are then ranked within their respective sectors based on their ESG performance score. The highest ranked companies in each sector are identified as eligible for inclusion in the Index until such point that the aggregate weight of companies in the sector reaches 50% of the market cap of such sector in the Base Index.

As of the date of this prospectus, a significant portion of the Index is comprised of companies in the consumer discretionary and information technology sectors.

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the Index. In addition, under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in the securities of large-capitalization companies. Large-capitalization companies are defined as companies that fall in the range of companies included in the MSCI USA Large Cap Index as of the last business day of the month in which its most recent reconstitution was completed. As of December 31, 2022, the MSCI USA Large Cap Index had a float-adjusted market capitalization range from $1.88 billion to $2.09 trillion, with an average market capitalization of $54.4 billion. “Float-adjusted” means that the share amounts used in calculating the Index reflect only shares available to investors, with shares held by control groups, public companies and government agencies excluded.

To the extent the Index concentrates (i.e., holds 25% or more of its total assets) in the securities of companies in a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the Index.

Principal Risks

in only a particular country, company, industry, or sector of the market. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.

Information Technology Sector Risk—The Fund currently invests a significant portion of its assets in the information technology sector, although this may change over time. The information technology sector can be significantly affected by changes in, among other things, the supply and demand for specific products and services, the pace of technological development and product obsolescence, market competition, government regulation, and patent and intellectual property rights.

Market Trading Risks—The Fund is an exchange-traded fund (“ETF”), and as with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of a Fund share typically will approximate its net asset value (“NAV”), there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy Fund shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

the Fund’s shares. In the event market makers cease making a market in the Fund’s shares or authorized participants stop submitting creation or redemption orders, Fund shares may trade at a larger premium or discount to NAV.

Fund Performance

During the period reflected in the bar chart above, the Fund’s highest and lowest quarterly returns were 23.02% and -19.82%, respectively, for the quarters ended June 30, 2020 and March 31, 2020.

The Fund seeks to track the investment results of the Index, which is comprised of equity securities with growth characteristics issued by large capitalization companies listed on U.S. exchanges that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects from the securities included in the MSCI USA Growth Index (the “Base Index”), which generally consists of large-and mid-capitalization U.S. equity securities that exhibit overall growth style characteristics based on five variables: long-term forward earnings per share (“EPS”) growth rate, short-term forward EPS growth rate, current internal growth rate, long-term historical EPS growth trend, and long-term historical sales per share growth trend.

Large-capitalization companies are defined as companies that fall in the range of companies included in the MSCI USA Large Cap Index as of the last business day of the month in which its most recent reconstitution was completed. As of December 31, 2022, the MSCI USA Large Cap Index had a float-adjusted market capitalization range from $658.68 million to $2.09 trillion, with an average market capitalization of $56.37 billion. “Float-adjusted” means that the share amounts used in calculating the Index reflect only shares available to investors, with shares held by control groups, public companies and government agencies excluded.

Principal Risks

Consumer Discretionary Sector Risk—The Fund currently invests a significant portion of its assets in the consumer discretionary sector, although this may change over time. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending.

Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider or a financial intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Growth Stock Risk—Growth stocks tend to be more volatile than certain other types of stocks and their prices usually fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market.

Principal Investment Strategies

The Fund seeks to track the investment results of the Index, which is comprised of equity securities with value characteristics issued by large capitalization companies listed on U.S. exchanges that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects from the securities included in the MSCI USA Value Index (the “Base Index”), which generally consists of large-and mid-capitalization U.S. equity securities that exhibit overall value style characteristics based on three variables: book value to price, 12-month forward earnings to price, and dividend yield. Securities in the Base Index are weighted based on market capitalization. MSCI Inc. (“MSCI”), is the index provider for the Index and the Base Index. The Index and the Base Index are owned, calculated and controlled by MSCI, in its sole discretion. Neither the Fund’s investment adviser, sub-adviser nor their affiliates has any discretion to select Index components or change the Index methodology.


Section 1 Fund Summaries	17

Companies that are not excluded by the ESG criteria are then ranked within their respective sectors based on their ESG performance score. The highest ranked companies in each sector are identified as eligible for inclusion in the Index until such point that the aggregate weight of companies in the sector reaches 50% of the market cap of such sector in the Base Index. For example, if the market capitalization of all consumer discretionary sector companies included in the Base Index totals $200 billion, then the Index would screen these consumer discretionary sector companies, rank them based on ESG performance scores, and add the highest scoring companies to the Index until such point that their combined total market capitalization reaches $100 billion. Those companies identified as eligible for inclusion in the Index are market capitalization weighted within their respective sectors. Once the universe of eligible Index components is established, the Index optimizes the market cap weightings of individual components to approximate the sector weightings of the Base Index, within certain constraints established by the Index. As of the date of this prospectus, a significant portion of the Index is comprised of companies in the health care and the financial services sectors.

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the Index. In addition, under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in the securities of large-capitalization companies. Large-capitalization companies are defined as companies that fall in the range of companies included in the MSCI USA Large Cap Index as of the last business day of the month in which its most recent reconstitution was completed. As of December 31, 2022, the MSCI USA Large Cap Index had a float-adjusted market capitalization range from $1.22 billion to $495.92 billion, with an average market capitalization of $43.04 billion. “Float-adjusted” means that the share amounts used in calculating the Index reflect only shares available to investors, with shares held by control groups, public companies and government agencies excluded.

Principal Risks


18	Section 1 Fund Summaries

Health Care Sector Risk—The Fund currently invests a significant portion of its assets in the health care sector, although this may change over time. Health care companies may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services, changes in patent and intellectual property rights and product liability claims, among other factors.


Section 1 Fund Summaries	19

may be especially pronounced for smaller funds). Trading of the Fund’s shares may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). In times of market stress, the Fund’s underlying portfolio holdings may become less liquid, which in turn may affect the liquidity of the Fund’s shares and/or lead to more significant differences between the Fund’s market price and its NAV. Market makers are under no obligation to make a market in the Fund’s shares, and authorized participants are not obligated to submit purchase or redemption orders for the Fund’s shares. In the event market makers cease making a market in the Fund’s shares or authorized participants stop submitting creation or redemption orders, Fund shares may trade at a larger premium or discount to NAV.

Value Stock Risk—Value stocks are securities of companies that typically trade at a perceived discount to their intrinsic value and at valuation discounts relative to companies in the same industry. Value stocks often times are also in sectors that trade at a discount to the broader market. The reasons for their discount may vary greatly, but some examples may include adverse business, industry or other developments that may cause the company to be subject to special risks. The intrinsic value of a stock with value characteristics may be difficult to identify and may not be fully recognized by the market for a long time or a stock identified to be undervalued may actually be appropriately priced at a low level.

Fund Performance

During the period reflected in the bar chart above, the Fund’s highest and lowest quarterly returns were 15.04% and -25.41%, respectively, for the quarters ended December 31, 2020 and March 31, 2020.

The Index selects from the securities included in the MSCI USA Mid-Cap Growth Index (the “Base Index”), which generally consists of mid-capitalization U.S. equity securities that exhibit overall growth style characteristics based on five variables: long-term forward earnings per share (“EPS”) growth rate, short-term forward EPS growth rate, current internal growth rate, long-term historical EPS growth trend, and long-term historical sales per share growth trend. Securities in the Base Index are weighted based on market capitalization. MSCI Inc. (“MSCI”) is the index provider for the Index and the Base Index.

practices and business ethics. The ESG criteria also consider how well a company adheres to national and international laws and regulations related to ESG matters. Index rules exclude companies with significant activities in the following controversial businesses: alcohol production, tobacco production, nuclear power, gambling, and weapons and firearm production. Companies otherwise eligible for inclusion in the Index that exceed certain carbon-based ownership and emissions thresholds are excluded from the Index.

Companies that are not excluded by the ESG criteria are then ranked within their respective sectors based on their ESG performance score. The highest ranked companies in each sector are identified as eligible for inclusion in the Index until such point that the aggregate weight of companies in the sector reaches 50% of the market cap of such sector in the Base Index.

As of the date of this prospectus, a significant portion of the Index is comprised of companies in the financial services sector.

In seeking to track the investment results of the Index, the Fund attempts to replicate the Index by investing all, or substantially all, of its assets the securities represented in the Index in approximately the same proportions as the Index. The Index is normally rebalanced and reconstituted quarterly in February, May, August, and November. The Index may also remove a security at any time in response to a corporate event such as bankruptcy, delisting, merger or acquisition that causes the security to become ineligible for inclusion in the Index. The Fund makes changes to its portfolio shortly after any Index changes are made public. As of December 31, 2022, the Index was comprised of 224 securities.

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the Index.

Section 2 Additional Detail About the Funds’ Strategies, Holdings and Risks

This prospectus contains important information about investing in the Funds. Please read this prospectus carefully before you make any investment decisions. Additional information regarding the Funds is available at www.nuveen.com/etf or by calling Nuveen Investor Services at (888) 290-9881.

Each Fund is designed to track an index that is not representative of the market as a whole. Each Fund is designed to be used as part of a broader asset allocation strategy, and thus an investment in a Fund should not be considered a complete investment program.

Each Index is a theoretical financial calculation, whereas a Fund is an actual investment portfolio. The performance of a Fund and its Index may vary for a number of reasons, including transaction costs, asset valuations, corporate actions (such as mergers and spin-offs), and differences between a Fund’s portfolio and its Index resulting from legal restrictions (such as tax diversification requirements) that apply to the Fund but not to the Index. On an annual basis, each Fund’s tracking error (i.e., the divergence of a Fund’s performance from that of its Index) is generally expected to be less than 5%.

Investment Objectives and Principal
Investment Strategies

Each Fund’s investment objective, which is described in the “Fund Summaries” section, may be changed by the Fund’s Board of Trustees (the “Board”) without shareholder approval.

Each Fund’s investment policies may be changed by the Board without shareholder approval unless otherwise noted in this prospectus or the statement of additional information.

Each Fund has adopted policies whereby, under normal market conditions, it will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in both companies with market capitalizations suggested by the Fund’s name, if applicable, and component securities of its Index (the “Name Policy”). If the Name Policy changes, you will be notified at least 60 days in advance. Each Fund may consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, the Funds will value eligible derivatives at fair value or market value and not notional value.

Each Fund’s principal investment strategies are discussed in the “Fund Summaries” section. These are the strategies that each Fund’s investment adviser and sub-adviser believe are most likely to be important in trying to achieve the Fund’s investment objective. This section provides more information about these strategies, as well as information about some additional strategies that the Funds’ sub-adviser uses, or may use, to achieve each Fund’s objective. You should be aware that each Fund may also use strategies and invest in securities that are not described in this prospectus, but that are described in the statement of additional information.

ESG Indexes

Each Fund seeks to track the investment results of its Index, which is comprised of securities that meet certain ESG criteria. Companies with significant involvement in certain controversial business activities, including alcohol production, tobacco production, nuclear power, gambling, and weapons and firearms production, are ineligible to be included in the Index. For purposes of this policy, as of the date of this prospectus, all companies that earn either 10% or more of their revenue or more than $1 billion in revenue ($3 billion in revenue for all conventional weapons manufacturers; 6000 MW of installed capacity or 10% or more of installed capacity attributed to nuclear sources for nuclear power generation) from the production of alcohol-, tobacco- and/or gambling-related products, gambling operations, and/or manufacturing conventional weapons, conventional weapon components or weapons systems are excluded from the Index. In addition, all civilian firearm companies classified as “producers” that earn more than 0% of revenue from civilian firearms are excluded from the Index. These percentage and dollar amount thresholds are subject to change in accordance with updates to the rules-based Index methodology. All companies with any tie to controversial weapons, such as cluster munitions, landmines, depleted uranium weapons, nuclear weapons, and biological/chemical weapons, blinding lasers, non-detectable fragments and incendiary weapons are also excluded. All companies involved in nuclear power generation, including nuclear fuel enrichment, uranium mining, and/or nuclear reactor design or construction, are also excluded from the Index. In addition, companies that surpass certain thresholds of installed capacity attributed to nuclear sources are also excluded. Securities with any ownership of fossil fuel reserves are ineligible for inclusion in the Index. Securities eligible for inclusion in the Index are then screened to remove those companies with the highest absolute emissions and the highest carbon emission intensity, relative to the other eligible securities, in accordance with the Index methodology and greenhouse gas emissions data provided by MSCI ESG Research, Inc.

Portfolio Holdings

Under normal market conditions, each Fund invests at least 80% of its assets, exclusive of collateral held from securities lending, in component securities of its Index. Each Index draws from the universe defined by its Base Index, which generally consists of equity securities listed on U.S. exchanges. Each Fund may also, as a non-principal strategy, invest up to 20% of its assets in securities and other instruments that the Fund’s sub-adviser believes will help it track its Index, such as shares of other investment companies (including other ETFs), derivative instruments (including forward contracts, futures contracts, options on futures contracts, options and swaps), and cash and cash equivalents. Additional information about each Fund’s portfolio holdings can be found below.

Equity Securities

The Funds invest in equity securities. Equity securities generally include common stocks; preferred securities; warrants to purchase common stocks and preferred securities; convertible debt securities that are either in the money or immediately convertible into common stocks or preferred securities; common and preferred securities issued by master limited partnerships and real estate investment trusts (“REITs”); depositary receipts; and other securities with equity characteristics.


38	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

REITs

As a non-principal investment strategy, each Fund may invest in REITs. REITs are publicly traded corporations or trusts that invest in residential or commercial real estate. REITs generally can be divided into the following three types:

· Equity REITs, which invest the majority of their assets directly in real property and derive their income primarily from rents and capital gains or real estate appreciation.

· Mortgage REITs, which invest the majority of their assets in real estate mortgage loans and derive their income primarily from interest payments.

· Hybrid REITs, which combine the characteristics of equity REITs and mortgage REITs.

The only REITs included in the Index are equity REITs. The Funds can invest in common stock, preferred securities and convertible securities issued by equity REITs.

Derivatives

As a non-principal investment strategy, each Fund may invest in derivatives. Generally, a derivative is a financial contract the value of which depends upon, or is derived from, the value of an underlying asset, reference rate or index. Derivatives generally take the form of contracts under which the parties agree to payments between them based upon the performance of a wide variety of underlying references, such as stocks, bonds, loans, commodities, interest rates, currency exchange rates, and various domestic and foreign indices. Examples of derivative instruments include forward currency contracts, currency and interest rate swaps, currency options, futures contracts, options on futures contracts and swap agreements.

Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on a Fund’s performance.

Investment Companies and Other Pooled Investment Vehicles

As a non-principal investment strategy, each Fund may invest in securities of other open-end or closed-end investment companies, including ETFs. As a shareholder in an investment company or other pooled investment vehicle, each Fund will bear its ratable share of that vehicle’s expenses, and would remain subject to payment of the Fund’s management fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent a Fund invests in an investment company or other pooled investment vehicle. In addition, each Fund will incur brokerage costs when purchasing and selling shares of ETFs. Securities of investment companies or other pooled investment vehicles may be leveraged, in which case the value and/or yield of such securities will tend to be more volatile than securities of unleveraged vehicles.

Cash Equivalents and Short-Term Investments

As a non-principal investment strategy, each Fund may invest in cash and in U.S. dollar-denominated high-quality money market instruments and other short-term securities,


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	39

including money market funds, in such proportions as warranted by prevailing market conditions and the Funds’ principal investment strategies. The Funds may temporarily invest without limit in such holdings for liquidity purposes. Being invested in these securities may keep a Fund from participating in a market upswing and prevent a Fund from achieving its investment objective.

Temporary Defensive Positions

In certain situations or market conditions, such as in the case of liquidity concerns and/or unusually large cash inflows or redemptions, a Fund may temporarily depart from its normal investment policies and strategies, provided that the alternative is consistent with the Fund’s investment objective and is in the best interest of the Fund’s shareholders.

Disclosure of Portfolio Holdings

A description of each Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio holdings is available in the Funds’ statement of additional information. In addition, the identities and quantities of the securities held by each Fund are disclosed on the Funds’ website.

Risks

Risk is inherent in all investing. Investing in the Funds involves risk, including the risk that you may receive little or no return on your investment or even that you may lose part or all of your investment. Therefore, before investing you should consider carefully the principal risks and certain other risks that you assume when you invest in the Funds. Descriptions of these risks listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Funds, regardless of the order in which it appears. Because of these risks, you should consider an investment in a Fund to be a long-term investment.

Principal Risks

Concentration risk: To the extent that a Fund’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector or asset class. Concentrated exposure to an industry or group of industries may cause a Fund to experience increased market price volatility compared to funds that invest more broadly in the overall market.

Consumer discretionary sector risk (Nuveen ESG Large-Cap Growth ("NULG") only): The Fund currently invests a significant portion of its assets in the consumer discretionary sector, although this may change over time. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Consumer discretionary companies may also be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability. Changes in demographics and consumer tastes can also affect the demand or, and success of, consumer discretionary products in the


40	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

marketplace. Consumer discretionary companies have historically been characterized as relatively cyclical and therefore more volatile in times of change.

Cybersecurity risk: Intentional cybersecurity breaches include: unauthorized access to systems, networks or devices (such as through “hacking” activity); infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. In addition, unintentional incidents can occur, such as the inadvertent release of confidential information (possibly resulting in the violation of applicable privacy laws).

A cybersecurity breach could result in the loss or theft of customer data or funds, the inability to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs. Such incidents could cause a Fund, a Fund’s investment adviser or sub-adviser, a financial intermediary, or other service providers to incur regulatory penalties, reputational damage, additional compliance costs or financial loss. Negative impacts on a Fund could include the inability to calculate NAV, transact business, process transactions on behalf of shareholders or safeguard data. In addition, such incidents could affect issuers in which a Fund invests, and thereby cause a Fund’s investments to lose value.

Dividend-paying security risk (Nuveen ESG Dividend Value ETF ("NUDV") only): The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time. The Fund may also be harmed by changes to the favorable federal income tax treatment generally afforded to dividends.

Equity security risk: Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time. Even a long-term investment approach cannot guarantee a profit. Price changes may occur in the market as a whole, or they may occur in only a particular country, company, industry, or sector of the market. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries. Adverse events in any part of the U.S. and global financial markets may have unexpected negative effects on equity markets. These events may at times result in unusually high market volatility, including short-term volatility, which could negatively affect Fund performance.

A variety of factors can negatively affect the price of a particular company's equity securities. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company's sector or industry, or changes in government regulations affecting the company or its industry. In addition, the types of securities in which a particular fund invests, such as value stocks, growth stocks, large-, mid- and/or small-capitalization stocks, may underperform the market as a whole.

ESG strategy risk: Because a Fund's ESG investment strategy will exclude securities of certain issuers for non-financial reasons based on the ESG criteria of an Index (i.e., companies that do not demonstrate relative strength in ESG characteristics or are


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	41

involved in certain prohibited activities), a Fund may forgo some market opportunities available to funds that do not use an ESG investment strategy or may be required to sell a security when it might otherwise be disadvantageous to do so. This may cause a Fund to underperform the stock market as a whole or other funds that do not use an ESG investment strategy. In addition, there is a risk that the companies identified by a Fund’s ESG investment strategy do not operate as expected when addressing ESG issues. A company’s ESG performance or practices or the Index’s or the sub-adviser’s assessment of those actions could vary over time, which could cause an Index to allocate to, and a Fund to be temporarily invested in companies that do not comply with an Index’s ESG criteria or a Fund’s approach towards considering ESG characteristics. There are significant differences in interpretations of what it means for a company to have positive ESG characteristics. As a result, the factors and criteria considered when generating ESG data and the results of such ESG research generally differ across ESG data providers. The evaluation of ESG factors is often subjective and the third-party ESG data provider used by the Index may not identify or evaluate every relevant ESG factor with respect to every Index constituent. While the sub-adviser believes the ESG criteria used by each Fund’s Index are reasonable, the portfolio decisions made by the Fund based on an Index’s ESG criteria may differ from the decisions of other investors or advisers based on their views and evaluations of ESG characteristics. As a result, a Fund may invest in securities that do not reflect the beliefs of any particular investor. In making investment decisions, the Index, and, in turn, the sub-adviser, relies on information and data that could be incomplete or erroneous, which could cause the Index and sub-adviser to incorrectly assess a company’s ESG characteristics. The third-party data provider may differ in the data it provides for a given security or between industries, or may only take into account one of many ESG-related components of a company. Furthermore, because ESG considerations are still an emerging area of investment focus, data availability and reporting with respect to ESG criteria may not always be available or may become unreliable. The successful implementation of the ESG component of each Fund’s Index methodology is therefore dependent in large part on the ESG factors considered and research methodologies employed by the Index's third-party ESG data provider, as well as the timely availability of accurate information.

Regulatory changes or interpretations regarding the definitions and/or use of ESG characteristics could have a material adverse effect on a Fund’s ability to invest in accordance with its investment policies and/or achieve its investment objective, as well as the ability of certain classes of investors to invest in funds, such as the Funds, whose strategies include ESG factors.

Financial services sector risk (NUDV, Nuveen ESG Large-Cap Value ETF (“NULV”), Nuveen ESG Mid-Cap Value ETF (“NUMV”) and Nuveen ESG Small-Cap ETF (“NUSC”) only): The Funds currently invest a significant portion of their assets in the financial services sector, although this may change over time. Securities of companies in the financial services sector can be significantly affected by changes in, among other things, interest rates, currency exchange rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, portfolio concentrations in geographic markets, industries or products (such as commercial and residential real estate loans) and competition from new entrants.

Growth stock risk (NULG and Nuveen ESG Mid-Cap Growth ETF (“NUMG”) only): The growth stocks in which a Fund invests tend to be more volatile than certain other types of stocks and their prices usually fluctuate more dramatically than the overall stock market. Growth stocks may be more expensive relative to their earnings or assets compared to other types of equity securities. Accordingly, a stock with growth


42	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market. In addition, growth stocks, at times, may not perform as well as value stocks or the stock market in general, and may be out of favor with investors for varying periods of time. Growth companies may be newer or smaller companies and may retain a large part of their earnings for research, development or investments in capital assets.

Health care sector risk (NULV and NUMG only): The Funds currently invest a significant portion of their assets in the health care sector, although this may change over time. Health care companies may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability.

Index provider risk: There is no assurance that an Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, an index provider may carry out an unscheduled rebalance or other modification of an Index constituents or weightings, which may increase a Fund’s costs. Unusual market conditions may cause an index provider to postpone a scheduled rebalance. Such a postponement in a time of market volatility could mean a constituent that would otherwise be removed at rebalance may remain, causing the performance and constituents of the index to vary from those expected under normal conditions. Index providers generally do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the indexes in which they license, and generally do not guarantee that an index will be calculated in accordance with its stated methodology. Losses or costs associated with any index provider errors generally will be borne by the Fund and its shareholders.

Industrials sector risk (NUDV and NUSC only): The Funds currently invest a significant portion of their assets in the industrials sector, although this may change over time. The value of securities issued by industrials companies may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. World events and changes in government regulations, import controls, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Industrials companies may be adversely affected by liability for environmental damage and product liability claims. Industrials companies may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Other factors that may impact industrials companies include intense competition, consolidation, spending trends, economic cycles, delays in modernization, labor relations, and e-commerce initiatives.

Information technology sector risk (Nuveen ESG Large-Cap ETF ("NULC"), NULG and NUMG only): The Funds currently invest a significant portion of their assets in the information technology sector, although this may change over time. Securities of companies in the information technology sector can be significantly affected by changes in, among other things, the supply and demand for specific products and services, the pace of technological development and product obsolescence, market competition, government regulation, and patent and intellectual property rights.


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	43

changing market conditions. As a result, a Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index. In addition, because the Index selects securities for inclusion based on ESG criteria, a Fund may forgo some market opportunities available to funds that do not use these criteria.

Large-cap company risk (NUDV, NULC, NULG and NULV only): While large-cap companies may be less volatile than those of mid-and small-cap companies, they still involve risk. To the extent a Fund invests in large capitalization companies, the Fund may underperform funds that invest primarily in securities of smaller capitalization companies during periods when the securities of such companies are in favor. Large-capitalization companies may be unable to respond as quickly as smaller capitalization companies to competitive challenges or to changes in business, product, financial or other market conditions.

Only certain institutional investors are eligible to purchase and redeem shares directly from a Fund at NAV. In addition, efficient trading in a Fund’s shares on the secondary market depends on the participation of firms acting as market makers and/or liquidity providers in the market place. To the extent these market maker and authorized participant firms exit the ETF business or otherwise significantly reduce their business activities and no other entities step forward to perform these functions, a Fund’s shares may trade at a material discount to NAV.

During periods of high market volatility, a Fund’s share may trade at a significant discount to its NAV, and in these circumstances certain types of brokerage orders may expose an investor to an increased risk of loss. A “stop order,” sometimes called a “stop-loss order,” may cause a Fund’s share to be sold at the next prevailing market price once the “stop” level is reached, which during a period of high volatility can be at a price that is substantially below NAV. By including a “limit” criteria with your brokerage order, you may be able to limit the size of the loss resulting from the execution of an ill-timed stop order.

Although each Fund’s shares are listed for trading on a national securities exchange, it is possible that an active trading market may not develop or be maintained, in which case transactions may occur at wider bid/ask spreads (discussed in further detail below). Trading of a Fund’s shares may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage).

Buying or selling a Fund’s shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of a Fund through a broker, you will likely incur a brokerage commission and other charges. In addition, you may incur the cost of the “spread;” that is, the difference between what investors are willing to pay for a Fund’s shares (the “bid” price) and the price at which they are willing to sell a Fund’s shares (the “ask” price). The spread, which varies over time based on trading


44	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

volume and market liquidity, is generally narrower if a Fund has more trading volume and market liquidity and wider if a Fund has less trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). A Fund’s spread may also be impacted by market volatility generally and the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds. Because of the costs inherent in buying or selling a Fund’s shares, frequent trading may detract significantly from investment results, and an investment in a Fund’s shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Mid-cap company risk (NUDV, NUMG and NUMV only): While securities of mid-cap companies may be slightly less volatile than those of small-cap companies, they still involve substantial risk. Mid-cap companies may have limited product lines, markets or financial resources, and they may be dependent on a limited management group. Securities of mid-cap companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or broader market averages in general.

Service provider operational risk: A Fund’s service providers, such as a Fund’s administrator, custodian or transfer agent, may experience disruptions or operating errors that could negatively impact a Fund. Although service providers are required to have appropriate operational risk management policies and procedures, and to take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors, it may not be possible to identify all of the operational risks that may affect a Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Small-cap company risk (NUSC only): Securities of small-cap companies involve substantial risk. These companies, which can include start-up companies offering emerging products or services, may lack the management expertise, financial resources, product diversification, and competitive strengths of larger companies. They may have limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Prices of small-cap securities may be subject to more abrupt or erratic movements than security prices of larger, more established companies or broader market averages in general. In addition, the frequency and volume of their trading may be less than is typical of larger companies, making them subject to wider price fluctuations and lower liquidity. In some cases, there could be difficulties in selling the securities of small-cap companies at the desired time and price, especially in situations of increased market volatility where a Fund may experience high levels of shareholder redemptions. Securities at the bottom end of the capitalization range of small-cap companies sometimes are referred to as “micro-cap” securities. These securities may be subject to extreme price volatility, as well as limited liquidity and limited research.

Tracking error risk: Tracking error is the divergence of a Fund’s performance from that of its Index. Tracking error may occur because of, for example, pricing differences, transaction costs, a Fund’s holding of uninvested cash, differences in timing of the accrual of distributions, changes to its Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because a Fund incurs fees and expenses, but its Index does not.


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	45

Value stock risk (NULV and NUMV only): Value stocks are securities of companies that typically trade at a perceived discount to their intrinsic value and at valuation discounts relative to companies in the same industry. Value stocks often times are also in sectors that trade at a discount to the broader market. The reasons for their discount may vary greatly, but some examples may include adverse business, industry or other developments that may cause the company to be subject to special risks. Finding undervalued stocks requires considerable research to identify the particular company, analyze its financial condition and prospects, and assess the likelihood that the stock’s underlying value will be recognized by the market and reflected in its price. The intrinsic value of a stock with value characteristics in which a Fund invests may be difficult to identify and may not be fully recognized by the market for a long time or a stock identified to be undervalued may actually be appropriately priced at a low level. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor the securities of value companies may underperform the securities of other companies.

Non-Principal Risks

Derivatives risk: The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. Operational risk generally refers to risk related to potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error, and legal risk generally refers to insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.

Derivatives can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by a Fund will not correlate with the asset, index or rate underlying the derivative contract. Changes in the value of a derivative may also create margin delivery or settlement obligations for a Fund.

The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the contract. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. These risks are heightened when the management team uses derivatives to enhance a Fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by a Fund.

A Fund may use derivatives to hedge risk. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.

In addition, when a Fund engages in certain derivative transactions, it is effectively leveraging its investments, which could result in exaggerated changes in the NAV of the Fund’s shares and can result in losses that exceed the amount originally invested. The success of a Fund’s derivatives strategies will depend on the sub-adviser’s ability to assess and predict the impact of market or economic developments on the underlying asset, index or rate and the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions.


46	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges. In addition, certain derivative instruments and markets may not be liquid, which means a Fund may not be able to close out a derivatives transaction in a cost-efficient manner.

Short positions in derivatives may involve greater risks than long positions, as the risk of loss on short positions is theoretically unlimited (unlike a long position, in which the risk of loss may be limited to the notional amount of the instrument).

Swap agreements may involve fees, commissions or other costs that may reduce a Fund’s gains from a swap agreement or may cause the Fund to lose money.

Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a Fund to close out a position when desired.

Options contracts may expire unexercised, which may cause a fund to realize a capital loss equal to the premium paid on a purchased option or a capital gain equal to the premium received on a written option.

Global economic risk: National and regional economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and securities prices around the world, which could negatively impact the value of a Fund’s investments. Major economic or political disruptions, particularly in large economies like China’s, may have global negative economic and market repercussions. Additionally, events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may adversely affect the global economy and the markets and issuers in which a Fund invests. Recent examples of such events include the outbreak of a novel coronavirus known as COVID-19 that was first detected in China in December 2019, Russia’s invasion of Ukraine, and heightened concerns regarding North Korea’s nuclear weapons and long-range ballistic missile programs. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a significant impact on the global economy. These events could also impair the information technology and other operational systems upon which a Fund’s service providers, including the investment adviser and sub-adviser, rely, and could otherwise disrupt the ability of employees of a Fund’s service providers to perform essential tasks on behalf of a Fund. Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect a Fund’s investments.

Other investment companies risk: When a Fund invests in other investment companies, such as ETFs, shareholders bear both their proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies. Furthermore, a Fund is exposed to the risks to which the other investment companies may be subject. For Funds that invest in index-based ETFs, while such ETFs seek to achieve the same returns as a particular market index, the performance of an ETF may diverge from the performance of such index (commonly known as tracking error).

Information regarding the Board’s approval of the investment management agreements is available in the Fund’s annual report for the fiscal year ended October 31, 2022.


Section 3 Fund Management	49

Section 4 Investing in the Funds

Purchase and Sale of Shares

Each Fund is an ETF, which differs from a mutual fund in important ways. Shares of a mutual fund are purchased and redeemed by all shareholders directly from the issuing fund at NAV. By contrast, most investors will buy and sell shares of the Funds through a broker on a national securities exchange, where each Fund’s shares are listed and trade throughout the day at market prices like shares of other publicly traded securities. The Funds do not impose any minimum investment for shares of a Fund purchased on an exchange or otherwise in the secondary market. Each Fund’s shares trade under the trading symbol listed on the cover of this prospectus.

Each Fund’s primary listing exchange is the Cboe BZX Exchange, Inc. (the “Listing Exchange”). The Listing Exchange is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth Holiday, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Book Entry

Shares of the Funds are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Funds and is recognized as the owner of all shares for all purposes.

Investors owning shares of a Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Funds. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Trading Prices

The trading prices of a Fund’s shares on the Listing Exchange generally differ from the Fund’s NAV and are affected by market forces such as the supply of and demand for the Fund’s shares as well as the securities held by the Fund, economic conditions and other factors. The price you pay or receive when you buy or sell your shares in the secondary market is based on the market price of a Fund’s shares, which may be more or less than the NAV of such shares.


50	Section 4 Investing in the Funds

Householding

Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Investments by Registered Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in the securities of other investment companies, including shares of the Funds. Registered investment companies are permitted to invest in the Funds beyond the limits set forth in Rule 12d1-4 under the 1940 Act, including that such investment companies enter into an agreement with the Funds.

Purchase and Redemption of Creation Units

Only certain institutional investors (typically market makers or other broker-dealers) who have entered into agreements with Nuveen Securities, LLC, the Funds’ distributor (the “Distributor”) (“Authorized Participants”), may purchase and redeem shares directly from the Funds at NAV and only in large blocks of shares or multiples thereof (“Creation Units”). Except when aggregated in Creation Units, shares are not redeemable by a Fund. An Authorized Participant must be either a DTC participant or a member of the Continuous Net Settlement System of the National Securities Clearing Corporation (“NSCC”).

The Funds generally issue and redeem Creation Units in exchange for a designated in-kind basket of Fund securities and/or a designated amount of cash (together, the “Basket”). Each day the Listing Exchange is open for trading (a “Business Day”), prior to the opening of trading, each Fund publishes that day’s Basket through NSCC or another method of public dissemination.

Orders from Authorized Participants to create or redeem Creation Units may only be placed on a Business Day and are subject to approval by the Distributor. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received and deemed acceptable by the Distributor.

Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Funds’ statement of additional information.

Distributor

Nuveen Securities, LLC, the Funds’ distributor, distributes Creation Units for the Funds on an agency basis. The Distributor does not maintain a secondary market in shares of the Funds. The Distributor has no role in determining the policies of the Funds or the securities that are purchased or sold by the Funds. The Distributor’s principal address is 333 West Wacker Drive, Chicago, Illinois 60606.


Section 4 Investing in the Funds	51

Distribution and Service Payments

Distribution and Service Plan

Each Fund has adopted a Distribution and Service Plan in accordance with Rule 12b-1 under the 1940 Act pursuant to which the Fund is authorized to pay fees at an annual rate of up to 0.25% of the Fund’s average daily net assets for the sale and distribution of the Fund’s shares. No distribution fees are currently charged to the Funds; there are no plans to impose distribution fees, and no such fees will be charged for at least twelve months from the date of this prospectus. Additionally, the implementation of any such fees would require approval by the Board prior to implementation. Because these fees would be paid out of a Fund’s assets on an on-going basis, if such fees are charged in the future, they would increase the cost of your investment and might cost you more over time than paying other types of sales charges.

Other Payments by the Adviser

The Adviser and/or its affiliates may make payments to broker-dealers, registered investment advisers, banks or other intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, data provision services, or their making shares of the Funds and certain other Nuveen ETFs available to their customers generally and in certain investment programs. Such payments, which may be significant to the intermediary, are not made by the Funds. Rather, such payments are made by the Adviser and/or its affiliates from their own resources, which come directly or indirectly in part from fees paid by the Nuveen ETFs complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Funds or other Nuveen ETFs over another investment. More information regarding these payments is contained in the Funds’ statement of additional information.


52	Section 4 Investing in the Funds

Frequent Trading

The Funds do not impose any restrictions on the frequency of purchases and redemptions (“frequent trading”); however, the Funds reserve the right to reject or limit purchases at any time as described in the statement of additional information. In determining that no restrictions on frequent trading were necessary, the Board evaluated the risks of frequent trading to the Funds and their shareholders. The Board considered that a Fund’s shares can only be purchased and redeemed directly from the Fund in Creation Units by Authorized Participants, and that the vast majority of trading in the Funds’ shares occurs on the secondary market. Because secondary market trades do not involve the Funds directly, the Board concluded that such trades were unlikely to cause many of the harmful effects of frequent trading, including dilution, disruption of portfolio management, increases in a Fund’s trading costs and the realization of capital gains. With respect to purchases and redemptions by Authorized Participants directly from the Funds that are effected in-kind (i.e., for securities), the Board concluded that those trades do not have the potential to cause the harmful effects that may result from frequent cash trades. To the extent that a Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board recognized that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund’s ability to achieve its investment objective. However, the Board noted that direct trading by Authorized Participants is critical to ensuring that a Fund’s shares trade at or close to NAV. In addition, the Board recognized that the Funds impose fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Funds in effecting trades.


Section 4 Investing in the Funds	53

Section 5 General Information

Dividends and Distributions

As a Fund shareholder, you are entitled to your share of the Fund’s income and net realized gains on its investments. Each Fund pays out substantially all of its net earnings to its shareholders as dividends and distributions.

Each Fund may earn interest from its investments in common stocks. These amounts, net of expenses and taxes (if applicable), are passed along to Fund shareholders as dividends. Dividends, if any, are declared and paid annually for each Fund except NUDV. Dividends, if any, are declared and paid quarterly with respect to NUDV.

Each Fund will generally realize short-term capital gains or losses whenever it sells assets held for one year or less. Net short-term capital gains will generally be treated as ordinary income when distributed to shareholders. Each Fund will generally realize long-term capital gains or losses whenever it sells assets held for more than one year. Net capital gains (the excess of a Fund’s net long-term capital gains over its net short-term capital losses) are distributed to shareholders once a year at year end.

Each Fund reserves the right to declare special distributions if such action is necessary or advisable to preserve its status as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Your broker is responsible for distributing any dividends and capital gain distributions to you.

Dividend Reinvestment Service

No dividend reinvestment service is provided by the Funds. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of a Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Funds purchased in the secondary market.

Taxes

As with any investment, you should consider how your investment in shares of the Funds will be taxed. The tax information in this prospectus is provided as general information, based on current laws, which may be changed by legislative, judicial or administrative action. You should not consider this summary to be a comprehensive explanation of the tax treatment of the Funds, or the tax consequences of an investment in the Funds. There is no guarantee that shares of the Funds will receive certain regulatory or accounting treatment. You should consult your own tax professional about the tax consequences of an investment in shares of the Funds. Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Funds make distributions, you sell Fund shares, or (for Authorized Participants only) you purchase or redeem Creation Units.


54	Section 5 General Information

Taxes and Tax Reporting

Each Fund intends to qualify each year for treatment as a regulated investment company. If it meets certain minimum distribution requirements, a regulated investment company is not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, a Fund’s failure to qualify as a regulated investment company or to meet minimum distribution requirements would result (if certain relief provisions were not available) in fund-level taxation and, consequently, a reduction in income available for distribution to shareholders.

Each Fund intends to make distributions that may be taxed as ordinary income or capital gains. Distributions of a Fund’s net capital gain are taxable as long-term capital gains regardless of how long you have owned your shares. For non-corporate shareholders, long-term capital gains are generally taxable at tax rates up to 20% (lower tax rates apply to individuals in lower tax brackets), while distributions from short-term capital gains and net investment income are generally taxable as ordinary income. The tax you pay on a given capital gains distribution depends generally on how long the Fund has held the portfolio securities it sold and not on how long you have owned your Fund shares.

Dividends that are reported by a Fund as qualified dividend income are generally taxable to non-corporate shareholders at tax rates of up to 20% (lower rates apply to individuals in lower tax brackets). Qualified dividend income generally is income derived from dividends paid to a Fund by U.S. corporations or certain foreign corporations that are either incorporated in a U.S. possession or eligible for tax benefits under certain U.S. income tax treaties. In addition, dividends that a Fund receives in respect of stock of certain foreign corporations may be qualified dividend income if that stock is readily tradable on an established U.S. securities market. For dividends to be taxed as qualified dividend income to a non-corporate shareholder, a Fund must satisfy certain holding period requirements with respect to the underlying stock and the non-corporate shareholder must satisfy holding period requirements with respect to his or her ownership of Fund shares. Holding periods may be suspended for these purposes for stock that is hedged.

Corporate shareholders may be entitled to a dividends-received deduction for the portion of dividends they receive from a Fund that are attributable to dividends received by the Fund from U.S. corporations, subject to certain limitations.

The sale of shares in your account may produce a gain or loss, and is a taxable event. Any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if you held the shares you sold for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as a short-term gain or loss, except that any capital loss on a sale of shares held for six months or less is treated as a long-term capital loss to the extent of long-term capital gain dividends paid with respect to such shares. The ability to deduct capital losses may be limited depending on your circumstances.

In general, your distributions are subject to federal income tax for the year in which they are paid. Distributions paid in January, but declared and payable to shareholders of record in October, November or December of the prior year, however, may be taxable to you in the prior year. Distributions are generally taxable even if they are paid from income or gains earned by a Fund before your investment (and thus were included in the price you paid for your shares).

REITs in which a Fund may invest often do not provide complete and final tax information to a Fund until after the time that a Fund issues a tax reporting statement. As


Section 5 General Information	55

a result, a Fund may at times find it necessary to reclassify the amount and character of its distributions after it issues a tax reporting statement. If this were to occur, the financial intermediary with whom you hold your shares will send you a corrected, final Form 1099-DIV to reflect the reclassified information.

Early in each year, you will receive a statement from the firm through which you hold your Fund shares detailing the amount and nature of all distributions that you were paid during the prior year. The tax status of your distributions is the same whether you reinvest them or elect to receive them in cash.

Dividends and distributions from the Funds and capital gain on the sale of Fund shares are generally taken into account in determining a shareholder’s “net investment income” for purposes of the Medicare contribution tax applicable to certain individuals, estates and trusts.

Distributions (other than capital gain dividends) paid to individual shareholders that are neither citizens nor residents of the U.S. or to foreign entities will generally be subject to a U.S. withholding tax at the rate of 30%, unless a lower treaty rate applies. Gains realized by foreign shareholders from the sale or other disposition of shares of a Fund generally are not subject to U.S. taxation, unless the recipient is an individual who is physically present in the U.S. for 183 days or more per year. A Fund may, under certain circumstances, report all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met. Different tax consequences may result if you are a foreign shareholder engaged in a trade or business within the United States or if you are a foreign shareholder entitled to claim the benefits of a tax treaty.

Please note that if you do not furnish the Fund with your correct Social Security number or employer identification number, you fail to provide certain certifications to the Fund, you fail to certify whether you are a U.S. citizen or a U.S. resident alien, or the Internal Revenue Service notifies the Fund to withhold, federal law requires the Fund to withhold federal income tax from your distributions and redemption proceeds at the applicable withholding rate.

Qualified Business Income

A portion of the Fund’s portfolio holdings may consist of REITs. For tax years beginning after December 31, 2017, the Tax Cuts and Jobs Act generally would allow a non-corporate taxpayer a deduction equal to the investor’s combined qualified business income, which would include 20% of the investor’s qualified REIT dividends. Treasury has issued regulations that allow regulated investment companies (“RICs”) such as a Fund to report a portion of their distributions that relate to dividends received from REITs as qualified REIT dividends eligible for the 20% deduction. The total amount of Fund distributions that qualify for this deduction is disclosed to investors on their Forms 1099-DIV, which are made available in February after the close of a calendar year.


56	Section 5 General Information

Buying or Selling Shares Close to a Record Date

Buying Fund shares shortly before the record date for a taxable dividend or capital gain distribution is commonly known as “buying the dividend” and generally should be avoided by taxable investors. The entire distribution may be taxable to you even though a portion of the distribution effectively represents a return of your purchase price.

Cost Basis Method

You may elect a cost basis method to apply to shares held in your account with your financial intermediary. The cost basis method you select will determine the order in which such shares are sold and how your cost basis information is calculated and subsequently reported to you and to the Internal Revenue Service. Please consult your tax advisor to determine which cost basis method best suits your specific situation. Please contact your financial intermediary for instructions on how to make your election. If you do not make an election, your financial intermediary will choose its own default cost basis method.

Taxes on Creation and Redemption of Creation Units

Gain or loss recognized by an Authorized Participant upon an issuance of Creation Units in exchange for securities, or upon a redemption of Creation Units, may be capital or ordinary gain or loss depending on the circumstances. Any capital gain or loss realized upon an issuance of Creation Units in exchange for securities will generally be treated as long-term capital gain or loss if the securities have been held for more than one year. Any capital gain or loss realized upon the redemption of a Creation Unit will generally be treated as long-term capital gain or loss if the Fund shares comprising the Creation Unit have been held for more than one year. Otherwise, such capital gains or losses are treated as short-term capital gains or losses.

Persons exchanging securities for Creation Units should consult their own tax advisors with respect to the tax treatment of any creation or redemption transaction and whether the wash sales rules apply and when a loss might be deductible. If you purchase or redeem Creation Units, you will be sent a confirmation statement showing how many Fund shares you purchased or redeemed and at what price.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Funds. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax advisor about the potential tax consequences of an investment in shares of the Funds under all applicable tax laws.


Section 5 General Information	57

Net Asset Value

Each Fund’s NAV is determined as of the close of trading (normally 4:00 p.m. New York time) on the New York Stock Exchange (“NYSE”) on each Business Day. Each Fund’s NAV per share is calculated by taking the value of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. Each Fund’s latest NAV per share is available on the Fund’s website at www.nuveen.com/etf.

In determining NAV, exchange-traded instruments generally are valued at the last reported sales price or official closing price on an exchange, if available. If such market quotations are not readily available or are not considered reliable, an exchange-traded instrument will be valued at its fair value as determined in good faith using procedures approved by the Adviser, subject to the oversight and review of the Board. For example, the fair value of an exchange-traded instrument may be determined using prices provided by independent pricing services or obtained from other sources, such as broker-dealer quotations. Independent pricing services typically value non-exchange-traded instruments utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows, and transactions for comparable instruments. In pricing certain instruments, the pricing services may consider information about an instrument’s issuer or market activity provided by the Adviser or Sub-Adviser.

The price of an exchange-traded instrument may be determined unreliable in various circumstances. For example, a price may be deemed unreliable if it has not changed for an identified period of time, or has changed from the previous day’s price by more than a threshold amount, and recent transactions and/or broker dealer price quotations differ materially from the price in question.

The Board has designated the Adviser as the Funds’ valuation designee pursuant to Rule 2a-5 under the 1940 Act and delegated to the Adviser the day-to-day responsibility of making fair value determinations. All fair value determinations made by the Adviser are subject to review by the Board. As a general principle, the fair value of a portfolio instrument is the amount that an owner might reasonably expect to receive upon the instrument’s current sale. A range of factors and analysis may be considered when determining fair value, including relevant market data, interest rates, credit considerations and/or issuer specific news. However, fair valuation involves subjective judgments, and it is possible that the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

Premium/Discount Information

Information showing the number of days the market price of each Fund’s shares was greater than the Fund’s NAV per share (i.e., at a premium) and the number of days it was less than the Fund’s NAV per share (i.e., at a discount) are made available on the Funds’ website at www.nuveen.com/etf.

Section 6 Financial Highlights

The financial highlights table is intended to help you understand each Fund’s financial performance for the past five fiscal years or, if shorter, for the period of operations for a Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions).

This has been derived from information that has been audited by KPMG LLP, whose report for the most recent fiscal year, along with each Fund’s financial statements, are included in the annual report, which is available upon request.

Principal Investment Strategies

The Fund seeks to track the investment results of the Index, which is comprised solely of listed equity securities issued by companies (and depositary receipts representing such securities) located in countries with developed markets, excluding the United States and Canada, that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects from the securities included in the MSCI EAFE Index (the “Base Index”), which currently consists of large- and mid-capitalization companies located in one of the following 21 developed market countries: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. Securities in the Base Index are weighted based on market capitalization. MSCI Inc. (“MSCI”) is the index provider for the Index and the Base Index. The Index and the Base Index are owned, calculated and controlled by MSCI, in its sole discretion. Neither the Fund’s investment adviser, sub-adviser nor their affiliates has any discretion to select Index components or change the Index methodology.

assessment categories can include how a company is addressing climate change, natural resource use, and waste management and emission management. Social evaluation categories can include a company’s relations with employees and suppliers, product safety and sourcing practices. Governance assessment categories can include governance practices and business ethics. The ESG criteria also consider how well a company adheres to national and international laws and regulations related to ESG matters. Index rules exclude companies with significant activities in the following controversial businesses: alcohol production, tobacco production, nuclear power, gambling, and weapons and firearms production. Companies otherwise eligible for inclusion in the Index that exceed certain carbon-based ownership and emissions thresholds are excluded from the Index.

Companies that are not excluded by the ESG criteria are then ranked within their respective sectors based on their ESG performance score. The highest ranked companies in each sector are identified as eligible for inclusion in the Index until such point that the aggregate weight of companies in the sector reaches 50% of the market cap of such sector in the Base Index. For example, if the market capitalization of all consumer discretionary sector companies included in the Base Index totals $200 billion, then the Index would screen these consumer discretionary sector companies, rank them based on ESG performance scores, and add the highest scoring companies to the Index until such point that their combined total market capitalization reaches $100 billion. Those companies identified as eligible for inclusion in the Index are market capitalization weighted within their respective sectors. Once the universe of eligible Index components is established, the Index optimizes the market cap weightings of individual components to approximate the sector weightings of the Base Index, within certain constraints established by the Index. As of the date of this prospectus, a significant portion of the Index is comprised of companies in the financial services and industrials sectors.

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the Index and depositary receipts representing securities in the Index. To the extent the Index concentrates (i.e., holds 25% or more of its total assets) in the securities of companies in a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the Index.

Principal Risks

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, the value of dividends and interest earned from such securities, and gains and losses realized on the sale of such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.


Section 1 Fund Summaries	3

Geographic Concentration Risk—To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region and/or the depositary receipts representing such securities, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. The Fund currently invests a significant portion of its assets in companies located in Japan and Europe, particularly the United Kingdom, although this may change over time.


4	Section 1 Fund Summaries

Market Trading Risks—The Fund is an exchange-traded fund (“ETF”), and as with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of a Fund share typically will approximate its net asset value (“NAV”), there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy Fund shares on the secondary market, and you may receive more or less than NAV when you sell those shares. In addition, the Funds’ underlying portfolio holdings trade on foreign exchanges that may be closed when the national securities exchange on which the Fund’s shares trade is open (and vice versa), which may result in larger differences between the Fund’s NAV and its market price than those experienced by ETFs that invest in domestic securities. Although the Fund’s shares are listed for trading on a national securities exchange, it is possible that an active trading market may not develop or be maintained, in which case transactions may occur at wider bid/ask spreads (which may be especially pronounced for smaller funds). Trading of the Fund’s shares may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). In times of market stress, the Fund’s underlying portfolio holdings may become less liquid, which in turn may affect the liquidity of the Fund’s shares and/or lead to more significant differences between the Fund’s market price and its NAV. Market makers are under no obligation to make a market in the Fund’s shares, and authorized participants are not obligated to submit purchase or redemption orders for the Fund’s shares. In the event market makers cease making a market in the Fund’s shares or authorized participants stop submitting creation or redemption orders, Fund shares may trade at a larger premium or discount to NAV.

The Fund seeks to track the investment results of the Index, which is comprised solely of listed equity securities issued by companies (and depositary receipts representing such securities) located in countries with emerging markets that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects from the securities included in the MSCI Emerging Markets Index (the “Base Index”), which currently consists of large- and mid-capitalization companies located in one of the following 26 emerging market countries: Argentina, Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, Philippines, Poland, Qatar, Russia, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates. Securities in the Base Index are weighted based on market capitalization. MSCI Inc. (“MSCI”), is the index provider for the Index and the Base Index. The Index and the Base Index are owned, calculated and controlled by MSCI, in its sole discretion.

Principal Risks


Section 1 Fund Summaries	9

less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.

Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. The Fund currently invests a significant portion of its assets in companies located in China and India, although this may change over time. The Fund's investments in China include companies operated through legal structures known as variable interest entities ("VIEs"), which are not formally recognized under Chinese law and are subject to the risk, among others, that China could cease to allow VIEs at any time or impose new restrictions on the structure, either of which could result in significant economic losses to the Fund.

Geographic Concentration Risk—To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region and/or the depositary receipts representing such securities, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. The Fund currently invests a significant portion of its assets in companies located in China, India and other Asian countries, although this may change over time.

the performance and constituents of the index to vary from those expected under normal conditions. Index providers generally do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the indexes in which they license, and generally do not guarantee that an index will be calculated in accordance with its stated methodology. Losses or costs associated with any index provider errors generally will be borne by the Fund and its shareholders.

Market Trading Risks—The Fund is an exchange-traded fund (“ETF”), and as with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of a Fund share typically will approximate its net asset value (“NAV”), there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy Fund shares on the secondary market, and you may receive more or less than NAV when you sell those shares. In addition, the Funds’ underlying portfolio holdings trade on foreign exchanges that may be closed when the national securities exchange on which the Fund’s shares trade is open (and vice versa), which may result in larger differences between the Fund’s NAV and its market price than those experienced by ETFs that invest in domestic securities. Although the Fund’s shares are listed for trading on a national securities exchange, it is possible that an active trading market may not develop or be maintained, in which case transactions may occur at wider bid/ask spreads (which may be especially pronounced for smaller funds).

Investment Strategies

Each Fund’s investment objective, which is described in the “Fund Summaries” section, may be changed by the Fund’s Board of Trustees (the “Board”) without shareholder approval.

Each Fund’s investment policies may be changed by the Board without shareholder approval unless otherwise noted in this prospectus or the statement of additional information.

Each Fund has adopted policies whereby, under normal market conditions, it will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of its Index and in depositary receipts representing securities in its Index (the “Name Policy”). If the Name Policy changes, you will be notified at least 60 days in advance. Each Fund may consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, the Funds will value eligible derivatives at fair value or market value and not notional value.

ESG Indexes

Portfolio Holdings

Under normal market conditions, each Fund invests at least 80% of its assets, exclusive of collateral held from securities lending, in component securities of its Index. Each Fund may also, as a non-principal strategy, invest up to 20% of its assets in securities and other instruments that the Fund’s sub-adviser believes will help it track its Index, such as shares of other investment companies (including other ETFs), derivative instruments (including forward contracts, futures contracts, options on futures contracts, options and swaps), and cash and cash equivalents. Additional information about each Fund’s portfolio holdings can be found below.

Equity Securities


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	15

REITs

· Equity REITs, which invest the majority of their assets directly in real property and derive their income primarily from rents and capital gains or real estate appreciation.

· Mortgage REITs, which invest the majority of their assets in real estate mortgage loans and derive their income primarily from interest payments.

· Hybrid REITs, which combine the characteristics of equity REITs and mortgage REITs.

The only REITs included in the Index are equity REITs. The Funds can invest in common stock, preferred securities and convertible securities issued by equity REITs.

Derivatives

Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on a Fund’s performance.

Emerging markets risk (Nuveen ESG Emerging Markets Equity ETF ("NUEM") only): The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. Emerging markets generally do not have the level of market efficiency and strict standards in accounting, auditing, financial reporting, recordkeeping and securities regulation to be on par with advanced economies. Obtaining disclosures comparable to frequency, availability and quality of disclosures required by securities in the U.S. may be difficult. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund to evaluate local companies or their potential impact on the Fund’s performance. Investments in emerging markets come with much greater risk due to political instability, domestic infrastructure problems and currency volatility. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims that are available in the U.S. (including derivative litigation), as well as regulatory oversight, authority and enforcement actions that are common in the U.S. by regulators, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue.

ESG strategy risk: Because a Fund’s ESG investment strategy will exclude securities of certain issuers for non-financial reasons based on the ESG criteria of an Index (i.e., companies that do not demonstrate relative strength in ESG characteristics or are involved in certain prohibited activities), a Fund may forgo some market opportunities available to funds that do not use an ESG investment strategy or may be required to sell a security when it might otherwise be disadvantageous to do so. This may cause a Fund to underperform the stock market as a whole or other funds that do not use an ESG


18	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

investment strategy. In addition, there is a risk that the companies identified by a Fund’s ESG investment strategy do not operate as expected when addressing ESG issues. A company’s ESG performance or practices or the Index’s or the sub-adviser’s assessment of those actions could vary over time, which could cause an Index to allocate to, and a Fund to be temporarily invested in companies that do not comply with an Index’s ESG criteria or a Fund’s approach towards considering ESG characteristics. There are significant differences in interpretations of what it means for a company to have positive ESG characteristics. As a result, the factors and criteria considered when generating ESG data and the results of such ESG research generally differ across ESG data providers. The evaluation of ESG factors is often subjective and the third-party ESG data provider used by the Index may not identify or evaluate every relevant ESG factor with respect to every Index constituent. While the sub-adviser believes the ESG criteria used by each Fund’s Index are reasonable, the portfolio decisions made by the Fund based on an Index’s ESG criteria may differ from the decisions of other investors or advisers based on their views and evaluations of ESG characteristics. As a result, a Fund may invest in securities that do not reflect the beliefs of any particular investor. In making investment decisions, the Index, and, in turn, the sub-adviser, relies on information and data that could be incomplete or erroneous, which could cause the Index and sub-adviser to incorrectly assess a company’s ESG characteristics. The third-party data provider may differ in the data it provides for a given security or between industries, or may only take into account one of many ESG-related components of a company. Furthermore, because ESG considerations are still an emerging area of investment focus, data availability and reporting with respect to ESG criteria may not always be available or may become unreliable. The successful implementation of the ESG component of each Fund’s Index methodology is therefore dependent in large part on the ESG factors considered and research methodologies employed by the Index's third-party ESG data provider, as well as the timely availability of accurate information.

Financial services sector risk: The Funds currently invest a significant portion of their assets in the financial services sector, although this may change over time. Securities of companies in the financial services sector can be significantly affected by changes in, among other things, interest rates, currency exchange rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, portfolio concentrations in geographic markets, industries or products (such as commercial and residential real estate loans) and competition from new entrants.

Foreign investment risk: Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to or different than those of issuers that are located in or principally operated in the United States due to political, social and economic developments abroad, different regulatory environments and laws, potential seizure by the government of company assets, higher taxation, withholding taxes on dividends and interest and limitations on the use or transfer of portfolio assets. If any of these events were to occur, the affected security may experience drastic declines. In the event of a seizure of assets by a non-U.S. government, a Fund could lose its entire investment in that particular country.

To the extent a Fund invests in depositary receipts, the Fund will be subject to many of the same risks as when investing directly in non-U.S. securities. The holder of an


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	19

unsponsored depositary receipt may have limited voting rights and may not receive as much information about the issuer of the underlying securities as would the holder of a sponsored depositary receipt.

Other non-U.S. investment risks include the following:

· Enforcing legal rights may be difficult, costly and slow in non-U.S. countries, and there may be special problems enforcing claims against non-U.S. governments.

· Non-U.S. companies may not be subject to accounting, auditing, financial reporting or recordkeeping standards or governmental supervision comparable to U.S. companies, and there may be less public information about their operations.

· Non-U.S. markets may be less liquid and more volatile and may be more difficult to value than U.S. markets.

· The U.S. and non-U.S. markets often rise and fall at different times or by different amounts due to economic or other developments, including armed conflict or political, social or diplomatic events, particular to a given country or region. This phenomenon would tend to lower the overall price volatility of a portfolio that included both U.S. and non-U.S. securities. Sometimes, however, global trends will cause the U.S. and non-U.S. markets to move in the same direction, reducing or eliminating the risk reduction benefit of international investing.

· Non-U.S. securities traded on foreign exchanges, particularly in emerging markets countries, may be subject to further risks due to the inexperience of local investment professionals and financial institutions, the possibility of permanent or temporary termination of trading, and greater spreads between bid and asked prices for securities. In addition, non-U.S. exchanges and investment professionals are subject to less governmental regulation, and commissions may be higher than in the United States. Also, there may be delays in the settlement of non-U.S. exchange transactions.

· A Fund’s income from non-U.S. issuers may be subject to non-U.S. withholding taxes. In some countries, a Fund also may be subject to taxes on trading profits and, on certain securities transactions, transfer or stamp duties tax. To the extent non-U.S. income taxes are paid by a Fund, U.S. shareholders may be entitled to a credit or deduction for U.S. tax purposes.

Some countries restrict to varying degrees foreign investment in their securities markets. In some circumstances, these restrictions may limit or preclude investment in certain countries or may increase the cost of investing in securities of particular companies. Non-U.S. countries may be subject to economic sanctions or other measures by the United States or other governments. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is impossible to predict. The imposition of sanctions could, among other things, cause a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world.

Sanctions and other similar measures could limit or prevent a Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact a Fund’s liquidity and performance.


20	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

To the extent a Fund invests a significant portion of its assets in the securities of companies in a single country or region (or depositary receipts representing such securities), it is more likely to be impacted by events or conditions affecting that country or region. Investment in a Fund may be more exposed to a single country or a region’s economic cycles, stock market valuations and currency, which could increase its risk compared with a more geographically diversified fund. In addition, political, social, regulatory, economic or environmental events that occur in a single country or region may adversely affect the values of that country or region’s securities and thus the holdings of the Fund.

Geographic concentration risk: To the extent a Fund invests a significant portion of its assets in the securities of companies in a single country or region (or depositary receipts representing such securities), it is more likely to be impacted by events or conditions affecting that country or region. Investment in a Fund may be more exposed to a single country or a region’s economic cycles, stock market valuations and currency, which could increase its risk compared with a more geographically diversified fund. In addition, political, social, regulatory, economic or environmental events that occur in a single country or region may adversely affect the values of that country or region’s securities and thus the holdings of the Fund.

Industrials sector risk (Nuveen ESG International Developed Markets Equity ETF ("NUDM") only): The Fund currently invests a significant portion of its assets in the industrials sector, although this may change over time. The value of securities issued by industrials companies may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. World events and changes in government regulations, import controls, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Industrials companies may be adversely affected by liability for environmental damage and product liability claims. Industrials companies may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Other factors that may impact industrials companies include intense competition, consolidation, spending trends, economic cycles, delays in modernization, labor relations, and e-commerce initiatives.

Information technology sector risk (NUEM only): The Fund currently invests a significant portion of its assets in the information technology sector, although this may change over time. Securities of companies in the information technology sector can be significantly affected by changes in, among other things, the supply and demand for specific products


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	21

and services, the pace of technological development and product obsolescence, market competition, government regulation, and patent and intellectual property rights.

Investment style risk: Each Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. Each Fund does not attempt to outperform its Index or take defensive positions in declining markets or in response to changing market conditions. As a result, a Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index. In addition, because the Index selects securities for inclusion based on ESG criteria, a Fund may forgo some market opportunities available to funds that do not use these criteria.

Market trading risks: As with all ETFs, a Fund’s shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of a Fund’s share typically will approximate its NAV, there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy a Fund’s shares on the secondary market, and you may receive more or less than NAV when you sell those shares. In times of market stress, a Fund’s underlying portfolio holdings may become less liquid, which in turn may affect the liquidity of the Fund’s shares and/or lead to more significant differences between a Fund’s market price and its NAV. In addition, the Funds’ underlying portfolio holdings trade on foreign exchanges that may be closed when the national securities exchange on which the Fund’s shares trade is open (and vice versa), which may result in larger differences between the Fund’s NAV and its market price than those experienced by ETFs that invest in domestic securities.


22	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

Fund’s shares (the “ask” price). The spread, which varies over time based on trading volume and market liquidity, is generally narrower if a Fund has more trading volume and market liquidity and wider if a Fund has less trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). A Fund’s spread may also be impacted by market volatility generally and the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds. Because of the costs inherent in buying or selling a Fund’s shares, frequent trading may detract significantly from investment results, and an investment in a Fund’s shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Mid-cap company risk: While securities of mid-cap companies may be slightly less volatile than those of small-cap companies, they still involve substantial risk. Mid-cap companies may have limited product lines, markets or financial resources, and they may be dependent on a limited management group. Securities of mid-cap companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or broader market averages in general.

Risks of investing in Asia (NUEM only): The Fund currently invests a significant portion of its assets in companies located in Asia, although this may change over time. Asia includes both developed and developing economies experiencing different stages of growth and prosperity. Although some Asian economies have experienced rapid rates of economic growth and industrialization recently, there is no guarantee these trends will continue. Further, certain Asian economies may experience currency devaluations and restrictions, high inflation, decreased exports, over-extension of credit, high unemployment rates, government corruption, and economic recessions. Investments in these countries may also be subject to heightened risk of expropriation, confiscatory taxation, piracy of intellectual property data, and political instability, including armed conflict and social unrest. In particular, any outbreak in hostilities between North and South Korea or any increased violence or terrorism in Indonesia or the Philippines could have a significant impact on the entire region and, potentially, the global economy. International trade and the commodities market are also very important to the economies of many Asian countries. Certain Asian countries are vulnerable to a decrease in the price of or global demand for certain commodities, such as oil, natural gas, and coal. The economic conditions of trading partners and neighboring nations as well as the inflow of international capital may also significantly impact these Asian countries’ economies. Certain governments in the region may also exert their influence over many aspects of the private sector in their respective countries and may own or control companies that compete against private enterprises.

Risks of investing in China (NUEM only): The Fund currently invests a significant portion of its assets in companies located in China, although this may change over time. Although the Chinese economy has grown rapidly during recent years and the Chinese government has implemented significant economic reforms to liberalize trade policy, promote foreign investment, and reduce government control of the economy, there can be no guarantee that economic growth or these reforms will continue. In particular, the Chinese economy may experience slower growth if global or domestic demand for Chinese goods decreases significantly. The Chinese economy is also susceptible to rising rates of inflation, economic recession, market inefficiency, volatility, and pricing anomalies that may be connected to governmental influence, a lack of publicly-available information and/or political and social instability. The government of China maintains strict currency controls on the yuan and Hong Kong dollar so that these currencies have historically traded in a tight range relative to the U.S. dollar. Given its


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	23

past intervention in the currency market, the Chinese government has been under pressure to manage its currency in a less restrictive fashion so that it is less correlated to the U.S. dollar. This could result in an increase in the value of the yuan and the Hong Kong dollar relative to the U.S. dollar, which could have a negative impact on Chinese exports and the overall Chinese economy. Trade tariffs or an economic downturn in any of the economies of China’s key trading partners could also have a detrimental impact on the Chinese economy. Investments in companies based or operated in China through legal structures known as variable interest entities (“VIEs”), which are not formally recognized under Chinese law, are subject to the risk, among others, that China could cease to allow VIEs at any time or impose new restrictions on the structure. It is also possible that the contractual arrangements underlying VIEs could be deemed unenforceable in China, which could limit (or eliminate) the remedies and rights available to the VIE and its investors and result in significant economic losses. Foreign investors are also subject to the risk of loss from expropriation or nationalization of their investment assets and property, governmental restrictions on foreign investments and the repatriation of capital invested. Adding to this risk, China’s authoritarian government has used force in the past to suppress civil dissent, and China’s foreign and domestic policies remain in conflict with those of Hong Kong as well as nationalist and religious groups in Xinjiang and Tibet. China’s growing income inequality and worsening environmental conditions also are factors that may affect the Chinese economy. From time to time and as recently as January 2020, China has experienced outbreaks of infectious illnesses, and the country may be subject to other infectious illnesses, diseases or other public health emergencies in the future. Any public health emergency could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on the Chinese economy, which in turn could adversely affect the Fund’s investments.

Risks of investing in Europe (NUDM only): The Fund currently invests a significant portion of its assets in companies located in Europe, including the United Kingdom, although this may change over time. The economies and markets of developed countries in Western Europe are interconnected. Events with a substantial impact on one European country typically impact its neighboring countries as well. For example, the extent and duration of Russia’s large-scale military invasion of Ukraine, initiated in February 2022, and the broad-ranging economic sanctions levied against Russia by the United States, the European Union, the United Kingdom, and other countries, remain unknown, but these events could have a significant adverse impact on Europe’s overall economy.

Most developed nations in Europe belong to the European Union (“EU”), and many of these nations also belong to the European Monetary Union (“EMU”) through which countries share a common currency, the euro, but are also subject to economic and monetary controls, such as restrictions on inflation rates, deficits, and debt levels. Unemployment remains high in many European countries, and several European countries continue to deal with significant debt problems. The default or threat of default of an EMU country on its sovereign debt may have a significant adverse effect on the economies of other European nations as well as the value of the euro. Changes in the supply and demand for imports and exports, EU and governmental regulations on trade, and currency exchange rates in Europe (e.g., between the euro and the British pound) may all have a substantial impact on European financial markets and the economies of European countries.

Effective January 1, 2021, the United Kingdom left the EU single market and customs union (“Brexit”) under the terms of a new trade agreement; however, there remains


24	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

considerable uncertainty about the potential trade, economic and market consequences of Brexit. The negative impact of the United Kingdom’s departure from the EU, as well as any future departures by other countries, could be significant, not only to the British and European economies, but also to the broader global economy. Such departures could potentially result in increased market volatility and illiquidity, and lower economic growth for companies that rely significantly on Europe for their business activities and revenues, which could negatively impact the value of the Fund’s investments.

Risks of investing in India (NUEM only): The Fund currently invests a significant portion of its assets in companies located in India, although this may change over time. Investments in Indian issuers may exhibit significantly greater market volatility than investments in issuers from more developed markets due to India’s unique legal, regulatory, political, currency and economic risks. Such investments are subject to political and legal uncertainty, greater government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets. These risks, among others, may result in higher potential losses for the Fund as well as higher transaction costs. The limited liquidity of the Indian securities markets, which is characterized by a small number of listed companies that have significantly smaller market capitalizations, may also affect the Fund’s ability to acquire or dispose of Indian securities at the price and time that the Fund desires. These factors, coupled with the lack of extensive accounting, auditing and financial reporting standards and practices, as compared to the United States, may increase the Fund’s risk of loss with respect to its investments in India. In addition, foreign investors may face restrictions on their investment opportunities in India, including limits on foreign ownership imposed by the Reserve Bank of India. Moreover, in the recent past, India has experienced civil unrest, religious conflicts, border disputes and hostilities with neighboring countries, including Pakistan, and terrorist threats from separatist movements in several Indian states. Incidents involving India’s or the region’s security may cause uncertainty in the Indian market and may adversely affect the Indian economy and the Fund’s investments.

Risks of investing in Japan (NUDM only): The Fund currently invests a significant portion of its assets in companies located in Japan, although this may change over time. Although Japan has recently emerged from a prolonged economic downturn that began in 2000, Japan’s economic growth rate may continue to lag the growth rates of neighboring Asian economies and other developed countries’ economies. Japan’s economy remains heavily dependent on international trade, and thus Japan’s economy may be adversely affected by trade tariffs, other protectionist measures, competition from developing nations, and political tensions with or downturns in the economies of its primary trading partners, including the United States, China, and other Southeast Asian countries. In addition, Japan relies on oil imports, and higher commodity prices could have a negative impact on the Japanese economy. In the past, the Japanese economy has been negatively affected by, among other factors, government intervention and protectionism, large government debt, relatively high unemployment rates, an aging population and workforce, and an unstable financial services sector. Japan is also vulnerable to natural disasters, such as earthquakes, typhoons, volcanic eruptions, and tsunamis, any one of which could significantly impact its economy and infrastructure.

Non-Principal Risks

Derivatives can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by a Fund will not correlate with the asset,


Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks	25

index or rate underlying the derivative contract. Changes in the value of a derivative may also create margin delivery or settlement obligations for a Fund.

Each Fund may also enter into over-the-counter (“OTC”) transactions in derivatives. Transactions in the OTC markets generally are conducted on a principal-to-principal basis. The terms and conditions of these instruments generally are not standardized and tend to be more specialized or complex, and the instruments may be harder to value. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges. In addition, certain derivative instruments and markets may not be liquid, which means a Fund may not be able to close out a derivatives transaction in a cost-efficient manner.

Swap agreements may involve fees, commissions or other costs that may reduce a Fund’s gains from a swap agreement or may cause the Fund to lose money.

Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a Fund to close out a position when desired.


26	Section 2 Additional Detail About the Funds' Strategies, Holdings and Risks

political disruptions, particularly in large economies like China’s, may have global negative economic and market repercussions. Additionally, events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may adversely affect the global economy and the markets and issuers in which a Fund invests. Recent examples of such events include the outbreak of a novel coronavirus known as COVID-19 that was first detected in China in December 2019, Russia’s invasion of Ukraine, and heightened concerns regarding North Korea’s nuclear weapons and long-range ballistic missile programs. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a significant impact on the global economy. These events could also impair the information technology and other operational systems upon which a Fund’s service providers, including the investment adviser and sub-adviser, rely, and could otherwise disrupt the ability of employees of a Fund’s service providers to perform essential tasks on behalf of a Fund. Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect a Fund’s investments.

company is not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, a Fund’s failure to qualify as a regulated investment company or to meet minimum distribution requirements would result (if certain relief provisions were not available) in fund-level taxation and, consequently, a reduction in income available for distribution to shareholders.

REITs in which a Fund may invest often do not provide complete and final tax information to a Fund until after the time that a Fund issues a tax reporting statement. As a result, a Fund may at times find it necessary to reclassify the amount and character of its distributions after it issues a tax reporting statement. If this were to occur, the financial intermediary with whom you hold your shares will send you a corrected, final Form 1099-DIV to reflect the reclassified information.

Foreign Investments by the Fund

Dividends, interest and other income received by the Funds with respect to foreign securities may give rise to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. The Funds may need to file special claims for refund to secure the benefit of a reduced rate. If as of the close of a taxable year more than 50% of the total assets of a Fund consist of stock or securities of foreign corporations, the Fund may elect to “pass through” to investors the amount of foreign income and similar taxes (including withholding taxes) paid by the Fund during that taxable year. If a Fund elects to “pass through” such foreign taxes, then investors will be considered to have received as additional income their respective shares of such foreign taxes, but may be entitled to

either a corresponding tax deduction in calculating taxable income, or, subject to certain limitations, a credit in calculating federal income tax.

Net Asset Value

The Funds invest in non-U.S. securities. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Funds are determined as of such times. The values of non-U.S. dollar denominated securities are converted to U.S. dollars using foreign currency exchange rates generally determined as of 4:00 p.m., London time. The value of non-U.S. securities held by the Funds may change on days when investors are not able to purchase or sell Fund shares.

THESE ETFs ARE DIFFERENT FROM TRADITIONAL ETFs

Traditional ETFs tell the public what assets they hold each day. These ETFs will not. This may create additional risks for your investment. For example:

· You may have to pay more money to trade these ETFs’ shares. These ETFs will provide less information to traders, who tend to charge more for trades when they have less information.

· The price you pay to buy ETF shares on an exchange may not match the value of the ETF’s portfolio. The same is true when you sell shares. These price differences may be greater for these ETFs compared to other ETFs because it provides less information to traders.

· These additional risks may be even greater in bad or uncertain market conditions.

· Each ETF will publish on its website each day a Proxy Portfolio (“Proxy Portfolio”) designed to help trading in shares of the ETF. While the Proxy Portfolio includes some of the ETF’s holdings, it is not the ETF’s actual portfolio.

The differences between these ETFs and other ETFs may also have advantages. By keeping certain information about the ETFs secret, these ETFs may face less risk that other traders can predict or copy their investment strategies. This may improve the ETFs’ performance. If other traders are able to copy or predict the ETFs’ investment strategies, however, this may hurt the ETFs’ performance.

For additional information regarding the unique attributes and risks of these ETFs, see the later discussion with respect to the Proxy Portfolios in the Funds’ principal investment strategies and associated risks, including “Proxy Portfolio Structure Risk,” “Authorized Participant Concentration Risk,” “Predatory Trading Practices Risk,” “Premium/Discount Risk,” “Trading Issues Risk” and “Tracking Error Risk,” as well as the “Investing in the Funds—Purchase and Sale of Fund Shares” and “Proxy Portfolio and Proxy Overlap” sections set forth below and the “Proxy Portfolio” and “Disclosure of Portfolio Holdings” sections in the Funds’ statement of additional information.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets in dividend-paying exchange-traded equity securities, which include common stocks and preferred securities. Companies in certain economic sectors of the market have historically provided higher dividend yields than companies in other sectors and industries. As a result, given the Fund’s focus on dividend-paying securities, the Fund may, from time to time, have a greater exposure to these higher dividend-yield sectors and industries than the broad equity market. The Fund defines dividend-paying equities as equity securities that have paid a dividend within the trailing twelve months and/or announced a dividend to be paid in the next twelve months at the time of purchase.

The Fund may invest in small-, mid- and large-cap companies. The Fund may invest up to 25% of its net assets in exchange-traded American Depositary Receipts (“ADRs”) and common stocks of non-U.S. issuers that are listed and trade on a foreign exchange contemporaneously with Fund shares.

Proxy Portfolio and the Fund’s actual portfolio (“Actual Portfolio”) holdings (the “Proxy Portfolio Disclosures”), which are intended to help keep the market price of the Fund’s shares trading at or close to the underlying net asset value (“NAV”) per share of the Fund. While the Proxy Portfolio includes some of the Fund’s holdings, it is not the Fund’s Actual Portfolio, and the Fund will not disclose the daily holdings of the Actual Portfolio. Although the Fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio to identify the Fund’s trading strategy, which if successful, could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the Fund and its shareholders. The Fund’s exemptive relief limits the types of securities in which the Fund can invest, which may constrain the Fund’s ability to implement its investment strategies. The Fund is actively managed and does not intend to track an index.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

Proxy Portfolio Structure Risk—Unlike traditional ETFs that provide daily disclosure of their portfolio holdings, the Fund does not disclose the daily holdings of the Actual Portfolio. Instead, the Fund discloses a Proxy Portfolio that is designed to reflect the economic exposure and risk characteristics of the Fund’s Actual Portfolio on any given trading day. Although the Proxy Portfolio and Proxy Portfolio Disclosures are intended to provide Authorized Participants (defined below) and other market participants with enough information to allow them to engage in effective arbitrage transactions that will keep the market price of the Fund’s shares trading at or close to the underlying NAV per share of the Fund, while at the same time enabling them to establish cost-effective hedging strategies to reduce risk, there is a risk that market prices will vary significantly from the underlying NAV of the Fund. See “Premium/Discount Risk.” Similarly, shares of the Fund may trade at a wider bid/ask spread than shares of traditional ETFs, and may therefore be more costly for investors to trade. See “Trading Issues Risk.” Also, the Fund will incur expenses to license the Proxy Portfolio mechanism, which may impact shareholder returns. Additionally, the proxy mechanism itself may result in additional trading costs, which also may negatively impact shareholder returns. In addition, although the Proxy Portfolio is designed to protect the Fund from predatory practices such as front-running and free-riding, market participants may nevertheless be able to use the Proxy Portfolio and Proxy Portfolio Disclosures to engage in trading practices that disadvantage the Fund. See “Predatory Trading Practices Risk.” The Fund will monitor on an ongoing basis the premium/discount between the market price and the NAV of the Fund’s shares, but there can be no assurance that the Proxy Portfolio methodology will operate as intended. The Proxy Portfolio methodology is novel and not yet proven as an effective arbitrage mechanism. The effectiveness of the Proxy Portfolio methodology as an arbitrage mechanism is contingent upon, among other things, the effectiveness of the Fund’s Factor Model analysis in creating a Proxy Portfolio that performs in a manner substantially identical to the performance of the Fund’s Actual Portfolio and the willingness of Authorized Participants and other market participants to trade based on the Proxy Portfolio. In the event that the Proxy Portfolio methodology does not result in effective arbitrage opportunities in the Fund shares, the Fund may exhibit wider premiums/discounts, bid/ask spreads and tracking error. At certain thresholds for such premiums/discounts, bid/ask spreads and tracking error, the Fund’s Board of Trustees will consider possible remedial measures, which may include liquidation or conversion to a fully-transparent, active ETF or a mutual fund.

· Premium/Discount Risk—Shares of the Fund are listed for trading on the NYSE Arca, Inc. (the “NYSE Arca”) and are bought and sold in the secondary market at market prices that may differ from their most recent NAV. The market value of the Fund’s shares will fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intraday value of the Fund’s holdings, and the relative supply and demand for the Fund’s shares on the exchange. Although the Proxy Portfolio is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of the Fund at or close to the Fund’s NAV, there is a risk (which may increase during periods of market disruption or volatility) that market prices for Fund shares will vary significantly from the Fund’s NAV. This risk may be greater for the Fund than for traditional ETFs that disclose their full portfolio holdings on a daily basis because the publication of the Proxy Portfolio does not provide the same level of transparency as the publication of the full portfolio by a fully transparent active ETF. This could cause the Fund’s shares to have wider bid/ask spreads and larger premiums/discounts than fully transparent ETFs using the same investment strategies. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for shares may result in shares trading at a significant premium or discount to NAV and/or in a reduced liquidity of your investment. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares and various types of orders that may be placed.


Section 1 Fund Summaries	3

Investors should consult their financial intermediary before purchasing or selling shares of the Fund. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

· Authorized Participant Concentration Risk—Only certain institutional investors (typically market makers or other broker-dealers) (“Authorized Participants”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants, none of which are or will be obligated to engage in creation or redemption transactions. To the extent that these institutions exit the business or are unable to process creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. The Fund’s novel structure may affect the number of entities willing to act as Authorized Participants, and this risk may be exacerbated during times of market stress.

· Predatory Trading Practices Risk—Although the Fund seeks to benefit from keeping its portfolio holdings information secret, market participants may attempt to use the Proxy Portfolio and related Proxy Portfolio Disclosures to identify the Fund’s holdings and trading strategy. If successful, this could result in such market participants engaging in predatory trading practices that could harm the Fund and its shareholders. The Proxy Portfolio and related Proxy Portfolio Disclosures have been designed to mitigate the risk that market participants could “reverse engineer” the Fund’s portfolio and investment strategy, but they may not be successful in this regard.

· Trading Issues Risk—Trading in Fund shares on the NYSE Arca may be halted in certain circumstances. If 10% or more of the Fund’s Actual Portfolio does not have readily available market quotations, the Fund will promptly request that the NYSE Arca halt trading in the Fund’s shares. Such trading halts may have a greater impact on the Fund compared to other ETFs due to its lack of transparency. If the trading of a security held in the Fund’s Actual Portfolio is halted or otherwise does not have readily available market quotations and the sub-adviser believes that the lack of any such readily available market quotations may affect the reliability of the Proxy Portfolio as an arbitrage vehicle or otherwise determines it is in the best interest of the Fund, the sub-adviser promptly will disclose on the Fund’s website the identity and weighting of such security for so long as such security’s trading is halted or otherwise does not have readily available market quotations and remains in the Actual Portfolio. There can be no assurance that the requirements of the NYSE Arca necessary to maintain the listing of the Fund will continue to be met. Because the Fund trades on the basis of a published Proxy Portfolio, it may trade at a wider bid/ask spread and may experience a wider premium/discount than traditional ETFs that publish their portfolios on a daily basis, and therefore, may cost investors more to trade especially during periods of market disruption or volatility.

· Tracking Error Risk—Although the Proxy Portfolio is designed to reflect the economic exposure and risk characteristics of the Fund’s Actual Portfolio on any given trading day, there is a risk that the performance of the Proxy Portfolio will diverge from the performance of the Actual Portfolio, potentially materially.

Active Management Risk—The Fund’s sub-adviser actively manages the Fund’s investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund’s sub-adviser may not produce the desired results. This could cause the Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.


4	Section 1 Fund Summaries

companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time.

Equity Security Risk—Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries. Holders of common stock generally are subject to more risks than holders of preferred securities because the status of common stockholders upon the bankruptcy of the issuer is subordinated to that of preferred security holders. Given the Fund’s focus on dividend-paying securities, the Fund may, from time to time, have a greater exposure to higher dividend-yield sectors and industries than the broad equity market which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.

Market Risk—The market value of the Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund’s investments whether or not the Fund invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund’s assets can decline.

Market Trading Risks—The Fund is an ETF, and as with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of a Fund share typically will approximate its NAV, there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy Fund shares on the secondary market, and you may receive more or less than NAV when you sell those shares. Although the Fund’s shares are listed for trading on a national securities exchange, it is possible that an active trading market may not develop or be maintained, in which case transactions may occur at wider bid/ask spreads (which may be especially pronounced for smaller funds). Trading of the Fund’s shares may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). In times of market stress, the Fund’s underlying portfolio holdings may become less liquid, which in turn may affect the liquidity of the Fund’s shares and/or lead to more significant differences between the Fund’s market price and its NAV. Market makers are under no obligation to make a market in the Fund’s shares, and Authorized Participants are not obligated to submit purchase or redemption orders for the Fund’s shares. In the event market makers cease making a market in the Fund’s shares or Authorized Participants stop submitting creation or redemption orders, Fund shares may trade at a larger premium or discount to NAV.

Preferred Security Risk—Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.


Section 1 Fund Summaries	5

Small- and Mid-Cap Company Risk—Securities of small-cap companies involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.

Fund Performance

During the period reflected in the bar chart above, the Fund’s highest and lowest quarterly returns were 12.47% and -12.18%, respectively, for the quarters ended December 31, 2022 and June 30, 2022.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Purchase and Sale of Fund Shares

The Fund is an actively managed, non-transparent ETF. Shares of the Fund are listed on a national securities exchange and can only be bought and sold in the secondary market through a broker-dealer at market prices. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (at a “premium”) or less than NAV (at a “discount”). An investor may also incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund shares (bid) and the lowest price a seller is willing to accept for Fund shares (ask) when buying and selling shares in the secondary market (the “bid/ask spread”). Recent information regarding the Fund, including its NAV, market price, premiums and discounts, and bid/ask spreads, is available on the Fund’s website at www.nuveen.com/etf.

Principal Investment Strategies

Under normal market conditions, the Fund seeks to achieve its investment objective by investing primarily in exchange-traded equity securities of U.S. companies with market capitalizations of at least $1 billion. The fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. At times and depending on market conditions, the Fund may also invest a significant percentage of its assets in a small number of business sectors or industries. The Fund may also invest up to 20% of its assets in exchange-traded American Depositary Receipts (“ADRs”) and common stocks of non-U.S. issuers, including emerging market issuers, that are listed and trade on a foreign exchange contemporaneously with Fund shares. Under normal conditions, the portfolio managers will select 40 to 65 stocks for the Fund’s portfolio. As of the date of this prospectus, the Fund invests a significant portion of its assets in companies in the information technology sector.

The portfolio managers attempt to include securities in the Fund’s portfolio that exhibit the greatest combination of earnings growth, quality business fundamentals, and attractive valuation relative to the broader market and peer group. The portfolio managers ordinarily look for several of the following characteristics when analyzing companies for potential inclusion within the Fund: attractive earnings growth, strong cash-flow outlook, a commitment to research and development, proprietary products and/or services, exposure to areas with emerging or expanding market share, a well-capitalized balance sheet, favorable or improving return on invested capital, integrity of the management team, and attractive relative valuation. In addition to exchange-traded equity securities (such as common stocks and preferred securities), the Fund may utilize U.S. listed, exchange-traded futures contracts.


8	Section 1 Fund Summaries

Non-Transparent ETF with Proxy Portfolio Structure. The Fund is a type of exchange-traded fund (“ETF”). Unlike traditional ETFs, however, which generally publish their portfolio holdings on a daily basis, the Fund discloses a portfolio transparency substitute—the “Proxy Portfolio”— and certain related information about the relative performance of the Proxy Portfolio and the Fund’s actual portfolio (“Actual Portfolio”) holdings (the “Proxy Portfolio Disclosures”), which are intended to help keep the market price of the Fund’s shares trading at or close to the underlying net asset value (“NAV”) per share of the Fund. While the Proxy Portfolio includes some of the Fund’s holdings, it is not the Fund’s Actual Portfolio, and the Fund will not disclose the daily holdings of the Actual Portfolio. Although the Fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio to identify the Fund’s trading strategy, which if successful, could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the Fund and its shareholders. The Fund’s exemptive relief limits the types of securities in which the Fund can invest, which may constrain the Fund’s ability to implement its investment strategies. The Fund is actively managed and does not intend to track an index.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.


Section 1 Fund Summaries	9

a significant premium or discount to NAV and/or in a reduced liquidity of your investment. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the Fund. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.


10	Section 1 Fund Summaries

Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Depositary Receipt Risk—To the extent the Fund invests in depositary receipts, the Fund will be subject to many of the same risks as when investing directly in non-U.S. securities, including risks associated with fluctuations in currency exchange rates as well as changes to the economic or political conditions in other countries. ADRs are depositary receipts issued by a U.S. financial institution that are listed and trade on a U.S. exchange. ADRs entitle their holder to all dividends and capital gains paid out on the underlying foreign shares. When the Fund invests in ADRs rather than investing directly in their underlying foreign shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with the return of the underlying foreign shares.

Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund’s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.

Futures Contract Risk—The use of futures contracts involves additional risks and transaction costs, which could leave the Fund in a worse position than if it had not used these instruments. Futures contracts may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in futures contracts could have a large impact on performance.


Section 1 Fund Summaries	11

Non-Diversification Risk—As a non-diversified fund, the Fund may invest a larger portion of its assets in the securities of a limited number of issuers and may be more sensitive to any single economic, business, political or regulatory occurrence affecting an issuer than a diversified fund. Poor performance by any one of these issuers would adversely affect the Fund to a greater extent than a more broadly diversified fund.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets in exchange-traded common stocks of small-capitalization companies. Small-capitalization companies are defined as companies that have market capitalizations within the market capitalization range of the companies in the Russell 2000^{^®} Index on the last business day of the month in which its most recent reconstitution was completed. Reconstitution of the index currently is completed in June of each year. On June 30, 2022, the range of the index was $25 million to $10.4 billion.

In selecting stocks, the Fund’s sub-adviser invests in companies that it believes meet one or more of the following criteria:

· Attractively valued relative to other companies in the same industry or market.

· Strong or improving cash flows, revenue and earnings growth, or other fundamentals.

· An identifiable catalyst that could increase the value of the company’s stock over the next one or two years.

The Fund’s sub-adviser will generally sell a stock if the stock hits its price target, the company’s fundamentals or competitive position significantly deteriorate, or if a better alternative exists in the marketplace.

The Fund may invest up to 15% of its total assets in non-dollar denominated common stocks of non-U.S. issuers listed on a foreign exchange that trade on such exchange contemporaneously with the shares of the Fund (“foreign common stocks”). In addition, the Fund may invest up to 25% of its total assets, collectively, in foreign common stocks and dollar-denominated equity securities of non-U.S. issuers that are either listed on a U.S. stock exchange or represented by


Section 1 Fund Summaries	15

exchange-traded American depositary receipts that are issued by a U.S. financial institution. Up to 15% of the Fund’s total assets may be invested in the securities of emerging market issuers.

transparent ETFs using the same investment strategies. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for shares may result in shares trading at a significant premium or discount to NAV and/or in a reduced liquidity of your investment. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the Fund. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, the value of dividends and interest earned from such securities, and gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.

Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Principal Investment Strategies

The Fund is actively managed and seeks to achieve its investment objective by investing, under normal market conditions, primarily in exchange-traded equity securities of large-cap U.S. companies that exhibit ESG characteristics, as described below. The Fund’s sub-adviser employs a fundamental, bottom-up investment process that centers on identifying growth companies which exhibit some or all of the following characteristics:

· in an industry with growth potential;

· leads or gains market share;

· has identifiable and sustainable competitive advantages;

· is managed by a team that can perpetuate the company’s competitive advantages;

· high, and preferably rising, return on invested capital;

· demonstrates sustainable Environmental, Social and Governance (ESG) characteristics;

· deploys excess cash flow to enhance shareholder returns; and

· demonstrates sound corporate governance.


Section 1 Fund Summaries	21

In order to identify investment candidates for the Fund, the sub-adviser begins by quantitatively screening companies in the Russell 1000^{^®} Index (the “Index’) as well as certain companies that exhibit similar financial qualities and market caps but are not otherwise in the Index. The screening process evaluates a company’s financial performance and certain ESG performance factors assigned scores by the sub-adviser based on data provided by independent ESG research vendors. The companies that pass this screen are then qualitatively assessed in the context of their respective industries.

As part of its qualitative assessment, the sub-adviser evaluates each company’s performance, relative to peers, with respect to ESG factors provided by independent ESG research vendors. The sub-adviser then determines which ESG factors may be material to a company’s future financial performance. This involves an evaluation of how the company integrates particular ESG risks and opportunities into its corporate strategy through, for example, improving governance practices, aligning management team incentives, and increasing transparency into its ESG practices. A potential investment candidate for the Fund will generally exhibit sustainable practices, as determined by the sub-adviser, across the following ESG factors:

· Environmental - impact on or from climate change, natural resource use and waste management practices;

· Social - human capital management, product safety, supply chain management; and

· Governance - corporate governance, business ethics and advocacy for governmental policy.

The ESG factor evaluation involves the identification of key performance indicators, which are given more or less relative weight compared to the broader range of potential assessment categories. Concerns in one area do not automatically eliminate a company from being an eligible portfolio investment. When ESG concerns exist, the sub-adviser gives careful consideration to how companies address the risks and opportunities they face in the context of their sector or industry and relative to their peers. The sub-adviser may engage with companies to encourage them to improve their ESG practices. The sub-adviser’s activities in this respect may include, but are not limited to, direct dialogue with company management, electronic communications and letters. The Fund may invest in companies whose ESG practices are currently suboptimal, with the expectation that these practices may improve over time either as a result of sub-adviser’s engagement efforts or through the company’s own initiatives.

ESG factors are evaluated by the sub-adviser based on data provided by independent ESG research vendors, and the sub-adviser favors companies with leadership in ESG factor performance relative to their peers. As the final step in the investment process, the sub-adviser determines which companies with potential for above-average future earnings growth fit its portfolio construction parameters in light of the companies’ valuations and relative ESG factor performance.

The Fund will not invest in companies that the sub-adviser determines are involved in the following activities:

· manufacturing of nuclear weapons, cluster munitions, land mines, incendiary devices, biological or chemical weapons, or depleted uranium munitions;

· civilian firearms manufacturing;

· tobacco products manufacturing; or

· thermal coal mining or production if it accounts for more than 30% of a company’s gross revenues.

Investing on the basis of ESG factor evaluation is generally qualitative and subjective by nature. Not every Fund investment will meet ESG performance indicators, or will do so at all times, and there can be no assurance that the ESG factor evaluation or any judgment exercised by the sub-adviser will reflect the beliefs or values of any particular investor.

The sub-adviser’s sell discipline utilizes the same fundamental research process in order to control risk and protect capital. Under normal market conditions, the sub-adviser employs a sell discipline pursuant to which it may sell some or all of its position in a stock when a stock becomes fully valued, the fundamental business prospects are deteriorating, the issuer’s ESG factor performance declines, or the position exceeds limits set by the sub-adviser.

The Fund, under normal market conditions, invests at least 80% of the sum of its net assets in exchange-traded equity securities of companies with large capitalizations at the time of purchase. For the purposes of this policy, companies with large capitalizations are defined as companies with market capitalizations in excess of $4 billion at the time of purchase. The Fund may invest up to 20% of its net assets in non-U.S. equity securities listed on a foreign exchange that trade on such exchange contemporaneously with the shares of the Fund.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.


Section 1 Fund Summaries	23

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, and gains and losses realized on the sale of such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.


24	Section 1 Fund Summaries

ESG Strategy Risk—Because the Fund’s ESG investment strategy will exclude securities of certain issuers for non-financial reasons (i.e., companies that do not demonstrate sustainable ESG characteristics or are involved in certain prohibited activities), the Fund may forgo some market opportunities available to funds that do not use an ESG investment strategy or may be required to sell a security when it might otherwise be disadvantageous to do so. This may cause the Fund to underperform the stock market as a whole or other funds that do not use an ESG investment strategy. In addition, there is a risk that the companies identified by the Fund’s ESG investment strategy will not operate as expected when addressing ESG issues or they will not exhibit positive ESG characteristics as intended.

Section 2 Additional Detail About the Funds’ Strategies, Holdings and Risks

Each Fund is an actively-managed, non-transparent ETF and does not intend to track an index. Unlike traditional ETFs that provide daily disclosure of their portfolio holdings, these Funds do not disclose the daily holdings of their actual portfolio. Instead, these Funds disclose a portfolio transparency substitute (a “Proxy Portfolio”) and certain related information about the relative performance of the Proxy Portfolio and the Fund’s actual portfolio (“Actual Portfolio”) holdings (the “Proxy Portfolio Disclosures”), which are intended to help keep the market price of the Fund’s shares trading at or close to the underlying NAV per share of the Fund. While the Proxy Portfolio includes some of the Fund’s holdings, it is not the Fund’s Actual Portfolio, and the Fund will not disclose the daily holdings of the Actual Portfolio. The Funds’ exemptive relief limits the types of securities in which each Fund can invest, which may constrain a Funds ability to implement its investment strategies.

Investment Objectives and Principal
Investment Strategies

Each Fund’s investment objective, which is described in the “Fund Summaries” section, may be changed by the Fund’s Board of Trustees (the “Board”) without shareholder approval.

Each Fund’s investment policies may be changed by the Board without shareholder approval unless otherwise noted in this prospectus or the statement of additional information.

The following Funds have each adopted a non-fundamental investment policy (a “Name Policy”), as follows.

· The Nuveen Dividend Growth ETF, under normal market conditions, invests at least 80% of the sum of its net assets in dividend-paying exchange-traded equity securities, which include common stocks and preferred securities. For the purposes of this policy, dividend-paying equities are defined as equity securities that have paid a dividend within the trailing twelve months and/or announced a dividend to be paid in the next twelve months at the time of purchase.

· The Nuveen Small Cap Select ETF, under normal market conditions, invests at least 80% of the sum of its net assets in exchange-traded common stocks of small-capitalization companies. For the purposes of this policy, small-capitalization companies are defined as companies that have market capitalizations within the market capitalization range of the companies in the Russell 2000^{^®} Index on the last business day of the month in which its most recent reconstitution was completed.

· The Nuveen Winslow Large-Cap Growth ESG ETF, under normal market conditions, invests at least 80% of the sum of its net assets in exchange-traded equity securities of companies with large capitalizations at the time of purchase.


28	Section 1 Fund Summaries

For the purposes of this policy, companies with large capitalizations are defined as companies with market capitalizations in excess of $4 billion at the time of purchase.

These Funds will consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, a Fund will value eligible derivatives at fair value or market value instead of notional value. As a result of having a Name Policy, each Fund must provide shareholders with a notice at least 60 days prior to any change of the Fund’s Name Policy.

Each Fund’s principal investment strategies are discussed in the “Fund Summaries” section. These are the strategies that each Fund’s investment adviser and sub-adviser believe are most likely to be important in trying to achieve the Fund’s investment objective. This section provides more information about these strategies, as well as information about some additional strategies that the Fund’s sub-adviser uses, or may use, to achieve the Fund’s objective. The strategies described below are principal investment strategies unless otherwise noted. You should be aware that a Fund may also use strategies and invest in securities that are not described in this prospectus, but that are described in the statement of additional information. For a copy of the statement of additional information, call Nuveen Investor Services at (888) 290-9881 or visit the Fund’s website at www.nuveen.com/etf.

Portfolio Holdings

Additional information about each Fund’s portfolio holdings can be found below.

Equity Securities

The Funds invest in exchange-traded equity securities, including common stocks, preferred securities, real estate investment trusts, and depositary receipts.

Non-U.S. Investments

The Funds may invest in common stocks of non-U.S. issuers that are listed and trade on a foreign exchange contemporaneously with Fund shares. The Funds will classify an issuer of a security as being a U.S. or non-U.S. issuer based on the determination of an unaffiliated, recognized financial data provider. Such determinations are based on a number of criteria, such as the issuer’s country of domicile, the primary exchange on which the security trades, the location from which the majority of the issuer’s revenue comes, and the issuer’s reporting currency. The Funds’ investment in non-U.S. equity securities may include direct investment in securities of non-U.S. companies traded overseas on a foreign exchange contemporaneously with Fund shares as well as ADRs.

The Nuveen Small Cap Select ETF may invest in issuers located in emerging markets. Emerging market countries include any country other than Canada, the United States and the countries comprising the MSCI EAFE^{^®} Index (currently, Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom).

Derivatives

As a non-principal investment strategy, the Nuveen Growth Opportunities ETF may invest in certain derivatives as part of its principal investment strategy. Generally, a derivative is a financial contract the value of which depends upon, or is derived from, the value of an underlying asset, reference rate or index. Derivatives generally take the form


Section 1 Fund Summaries	29

of contracts under which the parties agree to payments between them based upon the performance of a wide variety of underlying references, such as stocks, bonds, loans, commodities, interest rates, currency exchange rates, and various domestic and foreign indices. Examples of derivative instruments in which the Fund may invest include exchange-traded futures contracts that trade contemporaneously with Fund shares.

Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on the Fund’s performance.

Cash Equivalents and Short-Term Investments

As a non-principal investment strategy, the Funds may invest in cash and cash equivalents (short-term U.S. Treasury securities, government money market funds, and repurchase agreements only) in such proportions as warranted by prevailing market conditions and the Funds’ principal investment strategies. The Funds may temporarily invest without limit in such holdings for liquidity purposes, or in an attempt to respond to adverse market, economic, political or other conditions. Being invested in these securities may keep a Fund from participating in a market upswing and prevent a Fund from achieving its investment objective.

Investment Companies and Other Pooled Investment Vehicles

As a non-principal investment strategy, each Fund may invest in securities of other ETFs that invest primarily in securities of the types in which the Funds may invest directly. In addition, the Funds may invest a portion of their assets in pooled investment vehicles (other than investment companies) that invest primarily in securities of the types in which the Funds may invest directly. As a shareholder in an investment company or other pooled investment vehicle, each Fund will bear its ratable share of that vehicle’s expenses, and would remain subject to payment of the Fund’s management fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent a Fund invests in an investment company or other pooled investment vehicle. In addition, each Fund will incur brokerage costs when purchasing and selling shares of ETFs. Securities of investment companies or other pooled investment vehicles may be leveraged, in which case the value and/or yield of such securities will tend to be more volatile than securities of unleveraged vehicles.

Generally, investments in other investment companies (including ETFs) are subject to statutory limitations prescribed by the Investment Company Act of 1940, as amended ("1940 Act"). These limitations include a prohibition on a Fund acquiring more than 3% of the voting shares of any other investment company, and a prohibition on investing more than 5% of the Fund’s total assets in the securities of any one investment company or more than 10% of its total assets, in the aggregate, in investment company securities. Many ETFs, however, may rely on Rule 12d1-4 under the 1940 Act to permit funds to invest in the ETFs’ shares beyond these statutory limitations, subject to certain conditions and pursuant to a contractual arrangement between the ETFs and the investing Fund. The Funds may rely on Rule 12d1-4 to invest in ETFs beyond the foregoing statutory limitations. Subject to certain conditions, a Fund also may invest in money market funds beyond the statutory limits described above.

Preferred Securities

The Nuveen Dividend Growth ETF and Nuveen Growth Opportunities ETF may invest in exchange-traded preferred securities. Preferred securities, which generally pay fixed or adjustable rate dividends or interest to investors, have preference over common stock in the payment of dividends or interest and the liquidation of a company’s assets, which means that a company typically must pay dividends or interest on its preferred securities


30	Section 1 Fund Summaries

before paying any dividends on its common stock. On the other hand, preferred securities are junior to most other forms of the company’s debt, including both senior and subordinated debt. Because of their subordinated position in the capital structure of an issuer, the ability to defer dividend or interest payments for extended periods of time without triggering an event of default for the issuer, and certain other features, preferred securities are often treated as equity-like instruments by both issuers and investors, as their quality and value are heavily dependent on the profitability and cash flows of the issuer rather than on any legal claims to specific assets.

Securities Lending

The Funds may lend securities representing up to one-third of the value of its total assets to broker-dealers, banks, and other institutions to generate additional income. When a Fund loans its portfolio securities, it will receive, at the inception of each loan, cash collateral equal to at least 102% of the value of the loaned securities. Under the Fund’s securities lending agreement, the securities lending agent will generally bear the risk that a borrower may default on its obligation to return loaned securities. The Fund, however, will be responsible for the risks associated with the investment of cash collateral. The Fund may lose money on its investment of cash collateral or may fail to earn sufficient income on its investment to meet its obligations to the borrower.

When a dividend is paid on a security that is out on loan, the borrower receives the dividend and in turn makes a payment of the same amount to the Fund. Dividends, if they constitute “qualified dividends,” are taxable at the same rate as long-term capital gains. These payments made by borrowers, however, are not qualified dividends, and are taxable at higher ordinary income rates. As a result, some of the distributions received by shareholders who hold Fund shares in taxable accounts may be subject to taxation at a higher rate than if that Fund had not loaned its portfolio securities.

Temporary Defensive Positions

In certain situations or market conditions, a Fund may temporarily depart from its normal investment policies and strategies, provided that the alternative is consistent with the Fund’s investment objective and is in the best interest of the Fund’s shareholders.

Disclosure of Portfolio Holdings

A description of each Fund’s policies and procedures with respect to the disclosure of a Fund’s portfolio holdings is available in a Fund’s statement of additional information. A “snapshot” of each Fund’s investments may be found in its annual and semi-annual reports (when available). In addition, a complete list of each Fund’s portfolio holdings information is generally made available on a Fund’s website at www.nuveen.com/etf ten business days after the end of each month.

These holdings will remain accessible on the website until a Fund files its Form N-CSR or Form N-PORT with the SEC for the period that includes the date of the information. In addition, a list of each Fund’s top 10 holdings as of the end of each month is generally available approximately two to five business days after the end of the month on a Fund’s website at www.nuveen.com/etf.

Risks


Section 1 Fund Summaries	31

Each risk summarized below is considered a “principal risk” of investing in the Funds, regardless of the order in which it appears. Because of these risks, you should consider an investment in a Fund to be a long-term investment.

Principal Risks

Proxy Portfolio structure risk: Unlike traditional ETFs that provide daily disclosure of their portfolio holdings, the Funds do not disclose the daily holdings of the Actual Portfolio. Instead, a Fund discloses a Proxy Portfolio that is designed to reflect the economic exposure and risk characteristics of the Fund’s Actual Portfolio on any given trading day. Although the Proxy Portfolio and Proxy Portfolio Disclosures are intended to provide Authorized Participants and other market participants with enough information to allow them to engage in effective arbitrage transactions that will keep the market price of a Fund’s shares trading at or close to the underlying NAV per share of the Fund, while at the same time enabling them to establish cost-effective hedging strategies to reduce risk, there is a risk that market prices will vary significantly from the underlying NAV of the Fund. See “Premium/Discount Risk.” Similarly, shares of the Fund may trade at a wider bid/ask spread than shares of traditional ETFs, and may therefore be more costly for investors to trade. See “Trading Issues Risk.” Also, the Fund will incur expenses to license the Proxy Portfolio mechanism, which may impact shareholder returns. Additionally, the proxy mechanism itself may result in additional trading costs, which also may negatively impact shareholder returns. In addition, although the Proxy Portfolio is designed to protect a Fund from predatory practices such as front-running and free-riding, market participants may nevertheless be able to use the Proxy Portfolio and Proxy Portfolio Disclosures to engage in trading practices that disadvantage the Fund. See “Predatory Trading Practices Risk.” A Fund will monitor on an ongoing basis the premium/discount between the market price and the NAV of the Fund’s shares, but there can be no assurance that the Proxy Portfolio methodology will operate as intended. The Proxy Portfolio methodology is novel and not yet proven as an effective arbitrage mechanism. The effectiveness of the Proxy Portfolio methodology as an arbitrage mechanism is contingent upon, among other things, the effectiveness of the Fund’s Factor Model analysis in creating a Proxy Portfolio that performs in a manner substantially identical to the performance of the Fund’s Actual Portfolio and the willingness of Authorized Participants and other market participants to trade based on the Proxy Portfolio. In the event that the Proxy Portfolio methodology does not result in effective arbitrage opportunities in a Fund’s shares, the Fund may exhibit wider premiums/discounts, bid/ask spreads and tracking error. At certain thresholds for such premiums/discounts, bid/ask spreads and tracking error, the Fund’s Board of Trustees will consider possible remedial measures, which may include liquidation or conversion to a fully-transparent, active ETF or a mutual fund.

· Premium/discount risk: Shares of the Fund are listed for trading on the NYSE Arca and are bought and sold in the secondary market at market prices that may differ from their most recent NAV. The NAV of a Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market value of a Fund’s shares will fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intraday value of the Fund’s holdings, and the relative supply and demand for the Fund’s shares on the exchange. Although the disclosure of the Proxy Portfolio and Proxy Portfolio Disclosure is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of a Fund at or close to the Fund’s NAV, there is a risk (which may increase during periods of market disruption or volatility) that market prices for Fund shares will vary significantly from the Fund’s NAV. This risk may be greater for a Fund than for traditional ETFs that disclose


32	Section 1 Fund Summaries

their full portfolio holdings on a daily basis because publication of the Proxy Portfolio does not provide the same level of transparency as the publication of the full portfolio by a fully transparent active ETF. This could cause the Fund’s shares to have wider bid/ask spreads and larger premiums/discounts than fully transparent active ETFs using the same investment strategies. The Adviser and sub-advisers cannot predict whether shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related to, but not identical to, the same forces influencing the prices of the securities held by the Fund. While the creation/redemption feature is designed to make it more likely that a Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons, supply and demand imbalances and other factors. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for shares may result in shares trading at a significant premium or discount to NAV and/or in a reduced liquidity of your investment. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of a Fund. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

· Authorized Participant concentration risk: Only an Authorized Participant may engage in creation or redemption transactions directly with a Fund. A Fund has a limited number of institutions that act as Authorized Participants, none of which are or will be obligated to engage in creation or redemption transactions. To the extent that these institutions exit the business or are unable to process creation and/or redemption orders with respect to a Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, the Fund’s shares may trade at a discount to NAV and possibly face trading halts and/or delisting. The Fund’s novel structure may affect the number of entities willing to act as Authorized Participants, and this risk may be exacerbated during times of market stress.

· Predatory trading practices risk: Although a Fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio and related Proxy Portfolio Disclosures to identify the Fund’s holdings and trading strategy. If successful, this could result in such market participants engaging in predatory trading practices that could harm a Fund and its shareholders. The Proxy Portfolio and related Proxy Portfolio Disclosures have been designed to minimize the risk that market participants could “reverse engineer” a Fund’s portfolio and investment strategy, but they may not be successful in this regard.

· Trading issues risk: Although a Fund’s shares are listed on the NYSE Arca, there can be no assurance that an active or liquid trading market for them will develop or be maintained. Trading in Fund shares on the NYSE Arca may be halted due to market conditions or for reasons that, in the view of the NYSE Arca, make trading in shares inadvisable. If 10% or more of a Fund’s Actual Portfolio does not have readily available market quotations, the Fund will promptly request


Section 1 Fund Summaries	33

that the NYSE Arca halt trading in the Fund’s shares. Such trading halts may have a greater impact on the Fund compared to other ETFs due to a Fund’s lack of transparency. In addition, trading in shares on the NYSE Arca is subject to trading halts caused by extraordinary market volatility pursuant to the NYSE Arca’s “circuit breaker” rules (rules that require a halt in trading in a specific period of time when market prices decline by a specified percentage during the course of a trading day). If the trading of a security held in the Fund’s Actual Portfolio is halted or otherwise does not have readily available market quotations and the sub-adviser believes that the lack of any such readily available market quotations may affect the reliability of the Proxy Portfolio as an arbitrage vehicle or otherwise determines it is in the best interest of the Fund, the sub-adviser promptly will disclose on the Fund’s website the identity and weighting of such security for so long as such security’s trading is halted or otherwise does not have readily available market quotations and remains in the Actual Portfolio. There can be no assurance that the requirements of the NYSE Arca necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. In addition, an exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in a Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Because the Funds trade on the basis of published Proxy Portfolios, they may trade at a wider bid/ask spread and may experience a wider premium/ discount than traditional ETFs that publish their portfolios on a daily basis, and therefore, the Funds may cost investors more to trade especially during periods of market volatility.

· Tracking error risk: Although the Proxy Portfolio is designed to reflect the economic exposure and risk characteristics of a Fund’s Actual Portfolio on any given trading day, there is a risk that the performance of the Proxy Portfolio will diverge from the performance of the Actual Portfolio, potentially materially.

Active management risk: A Fund’s sub-adviser actively manages the Fund’s investments. Consequently, each Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund’s sub-adviser may not produce the desired results. This could cause a Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives. Additionally, legislative, regulatory or tax developments may affect the investment techniques available to a Fund’s sub-adviser in connection with managing a Fund and may also adversely affect the ability of a Fund to achieve its investment goal.

Concentration risk (Nuveen Small Cap Select ETF only): To the extent that a Fund’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector or asset class. Concentrated exposure to an industry or group of industries may cause a Fund to experience increased market price volatility compared to funds that invest more broadly in the overall market.


34	Section 1 Fund Summaries

Currency risk: Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities, and hence will affect the NAV of a fund that invests in such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of a fund to the extent it invests in such non-U.S. securities. Even though the non-U.S. securities held by Nuveen Dividend Growth Fund are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations.

Depositary receipts risk (Nuveen Growth Opportunities ETF only): To the extent the Fund invests in depositary receipts, the Fund will be subject to many of the same risks as when investing directly in non-U.S. securities, including risks associated with fluctuations in currency exchange rates as well as changes to the economic or political conditions in other countries. ADRs are depositary receipts issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange. When the Fund invests in ADRs rather than investing directly in their underlying foreign shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with the return of the underlying foreign shares. Sponsored ADRs are issued with the support of the issuer of the foreign shares underlying the ADRs and carry all of the rights of common shares, including voting rights. The holder of an unsponsored ADR may have limited voting rights and may not receive as much information about the issuer of the underlying securities as would the holder of a sponsored ADR. Because the underlying foreign shares of ADRs are typically denominated or quoted in non-U.S. currencies, currency exchange rates may affect the value of the Fund’s portfolio. Further, since an ADR’s underlying shares trade on foreign exchanges at times when U.S. markets are not open for trading, the value of the ADR’s underlying shares may change materially at times when U.S. markets are not open for trading, regardless of whether there is an active U.S. market for Fund shares.

Dividend-paying security risk (Nuveen Dividend Growth ETF only): The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate


Section 1 Fund Summaries	35

its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time. The Fund may also be harmed by changes to the favorable federal income tax treatment generally afforded to dividends.

Emerging markets risk (Nuveen Growth Opportunities ETF and Nuveen Small Cap Select ETF only): The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. Emerging markets generally do not have the level of market efficiency and strict standards in accounting, auditing, financial reporting, recordkeeping and securities regulation to be on par with advanced economies. Obtaining disclosures comparable to frequency, availability and quality of disclosures required by securities in the U.S. may be difficult. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund to evaluate local companies or their potential impact on the Fund’s performance. Investments in emerging markets come with much greater risk due to political instability, domestic infrastructure problems and currency volatility. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims that are available in the U.S. (including derivative litigation), as well as regulatory oversight, authority and enforcement actions that are common in the U.S. by regulators, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue.

Equity security risk: Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time. Even a long-term investment approach cannot guarantee a profit. Price changes may occur in the market as a whole, or they may occur in only a particular country, company, industry, or sector of the market. From time to time, a Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries. Adverse events in any part of the U.S. and global financial markets may have unexpected negative effects on equity markets. These events may at times result in unusually high market volatility, including short-term volatility, which could negatively affect Fund performance.

ESG strategy risk (Nuveen Winslow Large-Cap Growth ESG ETF only): Because the ETF's ESG investment strategy will exclude securities of certain issuers for non-financial reasons (i.e., companies that do not demonstrate sustainable ESG characteristics or are involved in certain prohibited activities), the Fund may forgo some market opportunities available to funds that do not use an ESG investment strategy or may be required to sell a security when it might otherwise be disadvantageous to do so. This may cause the Fund to underperform the stock market as a whole or other funds that do not use an ESG investment strategy. In addition, there is a risk that the companies identified by the Fund’s ESG investment strategy do not operate as expected when addressing ESG issues. A company’s ESG performance or practices could vary over time, which could


36	Section 1 Fund Summaries

cause the Fund to be temporarily invested in companies that do not comply with the Fund’s ESG criteria. There are significant differences in interpretations of what it means for a company to have positive ESG characteristics. While the sub-adviser believes its evaluation of ESG characteristics is reasonable, the decisions the sub-adviser makes may differ with other investors’ or advisers’ views regarding ESG characteristics. Further, in selecting companies for inclusion in the Fund’s portfolio, the sub-adviser relies on information and ESG performance data from an affiliated or third-party research provider, which could be incomplete or erroneous, which in turn could cause the sub-adviser to assess a company’s ESG characteristics incorrectly. The third-party data providers may differ in the data they provide for a given security or between industries, or may only take into account one of many ESG-related components of a company. Furthermore, data availability and reporting with respect to ESG criteria may not always be available or may become unreliable. Finally, the regulatory landscape with respect to ESG investing in the U.S. is still under development and, as a result, future regulations and/or rules adopted by applicable regulators could require the Fund to change or adjust its investment process with respect to ESG investing.

To the extent a Fund invests in depositary receipts, the Fund will be subject to many of the same risks as when investing directly in non-U.S. securities. The holder of an unsponsored depositary receipt may have limited voting rights and may not receive as much information about the issuer of the underlying securities as would the holder of a sponsored depositary receipt.

Other non-U.S. investment risks include the following:

· Enforcing legal rights may be difficult, costly and slow in non-U.S. countries, and there may be special problems enforcing claims against non-U.S. governments.

· Non-U.S. markets may be less liquid and more volatile and may be more difficult to value than U.S. markets.


Section 1 Fund Summaries	37

temporary termination of trading, and greater spreads between bid and asked prices for securities. In addition, non-U.S. exchanges and investment professionals are subject to less governmental regulation, and commissions may be higher than in the United States. Also, there may be delays in the settlement of non-U.S. exchange transactions.

Futures contract risk (Nuveen Growth Opportunities ETF only): The use of futures contracts involves additional risks and transaction costs, which could leave a Fund in a worse position than if it had not used these instruments. Futures contracts may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in futures contracts could have a large impact on performance. Additional risks associated with the use of futures contracts include: the risk of imperfect correlation, or even no correlation, between the price movements of the futures contracts and the price movements of the investments being hedged; losses caused by unanticipated market movements, which are potentially unlimited; the inability of the Fund’s sub-adviser to correctly predict the direction of securities prices and other economic factors; and the risk that a Fund may have to sell securities from its portfolio at a disadvantageous time if it has insufficient cash to meet margin requirements under the futures contract.

Growth stock risk (Nuveen Growth Opportunities ETF and Nuveen Winslow Large-Cap Growth ESG ETF only): The growth stocks in which each Fund invests tend to be more


38	Section 1 Fund Summaries

volatile than certain other types of stocks and their prices usually fluctuate more dramatically than the overall stock market. Growth stocks may be more expensive relative to their earnings or assets compared to other types of equity securities. Accordingly, a stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market. In addition, growth stocks, at times, may not perform as well as value stocks or the stock market in general, and may be out of favor with investors for varying periods of time. Growth companies may be newer or smaller companies and may retain a large part of their earnings for research, development or investments in capital assets.

Information technology sector risk (Nuveen Growth Opportunities ETF and Nuveen Winslow Large-Cap Growth ESG ETF only): Each Fund currently invests a significant portion of its assets in the information technology sector, although this may change over time. Securities of companies in the information technology sector can be significantly affected by changes in, among other things, the supply and demand for specific products and services, the pace of technological development and product obsolescence, market competition, government regulation, and patent and intellectual property rights.

Large-cap company risk (All Funds except Nuveen Small Cap Select ETF): While large-cap companies may be less volatile than those of mid-and small-cap companies, they still involve risk. To the extent a Fund invests in large capitalization companies, the Fund may underperform funds that invest primarily in securities of smaller capitalization companies during periods when the securities of such companies are in favor. Large-capitalization companies may be unable to respond as quickly as smaller capitalization companies to competitive challenges or to changes in business, product, financial or other market conditions.

Market risk: The market value of a Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time. Market values may change due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly within a specific country, region, industry, sector or asset class. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact issuers in a different country or region. As a result, the value of a Fund’s investments may be negatively affected whether or not the Fund invests in a country or region directly impacted by such conditions or events.

Additionally, unexpected events and their aftermaths, including broad financial dislocations (such as the “great recession” of 2008-09), war, armed conflict (such as Russia’s invasion of Ukraine in February of 2022), terrorism, the imposition of economic sanctions, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies (such as the COVID-19 coronavirus pandemic first detected in December of 2019), may adversely affect the global economy and the markets and issuers in which a Fund invests. These events could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, or wide-spread unemployment, and generally have a severe negative impact on the global economy. Such events could also impair the information technology and other operational systems upon which a Fund’s service providers, including the investment adviser and sub-adviser, rely, and could otherwise disrupt the ability of employees of a Fund’s service providers to perform essential tasks on behalf of a Fund. Furthermore, such events could cause financial markets to experience elevated or even extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. In addition, sanctions and other measures could limit or


Section 1 Fund Summaries	39

prevent a Fund from buying and selling securities (in sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact liquidity and performance. Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the value of a Fund’s investments. In addition, there is a possibility that the rising prices of goods and services may have an effect on a Fund. As inflation increases, the value of a Fund’s assets can decline.


40	Section 1 Fund Summaries

(which is often the case for funds that are newly launched or small in size). A Fund’s spread may also be impacted by market volatility generally and the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds. Because of the costs inherent in buying or selling a Fund’s shares, frequent trading may detract significantly from investment results, and an investment in a Fund’s shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Non-diversification risk (Nuveen Growth Opportunities ETF and Nuveen Winslow Large-Cap Growth ESG ETF only): Each Fund is a non-diversified fund and may invest a larger portion of its assets in a fewer number of issuers than a diversified fund. Because a relatively high percentage of a Fund’s assets may be invested in the securities of a limited number of issuers, a Fund’s portfolio and, therefore, performance may be more susceptible to any single economic, business (either globally or with respect to a particular company or companies), political or regulatory occurrence affecting an issuer than the portfolio of a diversified fund. Poor performance by any one of these issuers would adversely affect a Fund to a greater extent than a more broadly diversified fund and each Fund’s share price may fluctuate more than that of a comparable diversified fund.

Preferred security risk (Nuveen Dividend Growth ETF and Nuveen Growth Opportunities ETF only): There are special risks associated with investing in exchange-traded preferred securities:

Limited voting rights. Generally, preferred security holders have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights.

In the case of certain preferred securities issued by trusts or special purpose entities, holders generally have no voting rights except if a declaration of default occurs and is continuing. In such an event, preferred security holders generally would have the right to appoint and authorize a trustee to enforce the Trust’s or special purpose entity’s rights as a creditor under the agreement with its operating company.

Special redemption rights. In certain circumstances, an issuer of preferred securities may redeem the securities prior to their stated maturity date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws or by regulatory or major corporate action. As with call provisions, a redemption by the issuer may negatively impact the return of the security held by a Fund.

Payment deferral. Generally, preferred securities may be subject to provisions that allow an issuer, under certain conditions, to skip (“non-cumulative” preferred securities) or defer (“cumulative” preferred securities) distributions without any adverse consequences to the issuer. Non-cumulative preferred securities can skip distributions indefinitely. Cumulative preferred securities typically contain provisions that allow an issuer, at its discretion, to defer distributions payments for up to 10 years. If a Fund owns a preferred security that is deferring its distribution, the Fund may be required to report income for tax purposes although it has not yet received such income. In addition, recent changes in bank


Section 1 Fund Summaries	41

regulations may increase the likelihood of issuers deferring or skipping distributions.

Subordination. Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore are subject to greater credit risk than those debt instruments.

Floating Rate Payments. The dividend or interest rates on preferred securities may be floating, or convert from fixed to floating at a specified future time. The market value of floating rate securities may fall in a declining interest rate environment and may also fall in a rising interest rate environment if there is a lag between the rise in interest rates and the reset. This risk may also be present with respect to fixed rate securities that will convert to a floating rate at a future time. A secondary risk associated with declining interest rates is the risk that income earned by a Fund on floating rate securities may decline due to lower coupon payments on the floating-rate securities. Finally, many financial instruments use or may use a floating rate based upon the London Interbank Offered Rate, or "LIBOR," which is expected to be phased out. Any potential effects of the transition away from LIBOR on a Fund or on certain instruments in which a Fund invests can be difficult to ascertain, and they may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. In addition, interest rate provisions included in such contracts may need to be renegotiated in contemplation of the transition away from LIBOR. The transition may also result in a reduction in the value of certain instruments held by a Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of a Fund that holds such instrument. The usefulness of LIBOR as a benchmark could deteriorate during the transition period and, at this time, it is not possible to predict the effect of the establishment of replacement rates or any other reforms to LIBOR. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to a Fund.

Fixed Rate Payments. The market value of preferred securities with fixed dividends or interest rates may decline in a rising interest rate environment.

Liquidity. Preferred securities may be substantially less liquid than many other securities, such as U.S. government securities or common stock. Less liquid securities involve the risk that the securities will not be able to be sold at the time desired by a Fund or at prices approximating the values at which the Fund is carrying the securities on its books.

Financial services industry. The preferred securities market is comprised predominately of securities issued by companies in the financial services industry. Therefore, preferred securities present substantially increased risks at times of financial turmoil, which could affect financial services companies more than companies in other sectors and industries.

Tax risk. A Fund may invest in preferred securities or other securities the federal income tax treatment of which may not be clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult for a Fund to comply with the tax requirements applicable to regulated investment companies if the tax characterization of the Fund’s investments or the tax


42	Section 1 Fund Summaries

treatment of the income from such investments were successfully challenged by the Internal Revenue Service.

Regulatory risk. Issuers of preferred securities may be in industries that are heavily regulated and that may receive government funding. The value of preferred securities issued by these companies may be affected by changes in government policy, such as increased regulation, ownership restrictions, deregulation or reduced government funding.

Small- and mid-cap company risk (Nuveen Dividend Growth ETF only): Securities of small-cap companies involve substantial risk. These companies, which can include start-up companies offering emerging products or services, may lack the management expertise, product diversification, and competitive strengths of larger companies. They may have limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Prices of small-cap securities may be subject to more abrupt or erratic movements than security prices of larger, more established companies or broader market averages in general. In addition, the frequency and volume of their trading may be less than is typical of larger companies, making them subject to wider price fluctuations and lower liquidity. In some cases, there could be difficulties in selling the securities of small-cap companies at the desired time and price, especially in situations of increased market volatility where a Fund may experience high levels of shareholder redemptions. Securities at the bottom end of the capitalization range of small-cap companies sometimes are referred to as “micro-cap” securities. These securities may be subject to extreme price volatility, as well as limited liquidity and limited research. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.

Section 4 Investing in the Funds

Purchase and Sale of Shares

Purchasing or selling shares of a Fund on an exchange or other secondary market typically involves two types of costs. When purchasing or selling shares of a Fund through a broker, you may incur a brokerage commission. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread,” that is, any difference on the exchange between the bid price and the ask price for a share of a Fund. The spread will vary over time based on a Fund’s trading volume and market liquidity. The Funds have the potential for wider spreads given their non-transparent structure, especially during periods of market stress or volatility. Shares of the Funds trade on an exchange at prices that may differ to varying degrees from the daily NAV of the shares.

Each Fund’s primary listing exchange is the NYSE Arca (the “Listing Exchange”). The Listing Exchange is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth Holiday, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Proxy Portfolio Methodology

Unlike a traditional ETF, a Fund does not disclose its portfolio holdings daily. Rather, a Fund discloses a portfolio transparency substitute—the “Proxy Portfolio”—and certain related information about the relative performance of the Proxy Portfolio and a Fund’s Actual Portfolio holdings, which are designed to facilitate an effective arbitrage mechanism for a Fund’s shares while protecting the identity of a Fund’s full portfolio holdings. A Fund believes that daily disclosure of its full portfolio holdings could enable market participants to predict a Fund’s trading strategy and trade ahead of a Fund’s portfolio trades (a practice known as “front-running”), or to copy a Fund’s investment strategy (a practice known as “free riding”). The purpose of the proxy portfolio methodology, as described below (the “Proxy Portfolio Methodology”) is to protect a Fund and its shareholders against such practices. Although a Fund does not publish its full portfolio holdings daily, the Proxy Portfolio Methodology is designed to allow Authorized Participants and other market makers to assess the intraday value and associated risk characteristics of a Fund’s then-current portfolio holdings (the “Actual Portfolio”).

An important feature of the Proxy Portfolio methodology is the daily disclosure of a basket of cash and securities—the Proxy Portfolio—that is designed and constructed to closely track the daily performance of a Fund’s Actual Portfolio. In addition to the Proxy Portfolio, a Fund will disclose daily the percentage weight overlap between the holdings


48	Section 4 Investing in the Funds

of the Proxy Portfolio and the Actual Portfolio that formed the basis for a Fund’s calculation of NAV at the end of the prior Business Day (the “Proxy Overlap”). Daily disclosure of the Proxy Portfolio, the Proxy Overlap and the other related Proxy Portfolio Disclosures is designed to enable Authorized Participants and other market participants to accurately assess the profitability of arbitrage trades in shares of a Fund and to effectively hedge their risks associated with arbitrage and market making activities, thereby helping to ensure that investors can purchase and sell Fund shares in the secondary market at prices that are at or close to the underlying NAV per share of a Fund.

Proxy Portfolio

The goal of the Proxy Portfolio Methodology is to permit a Fund’s Proxy Portfolio, during all market conditions, to track closely the daily performance of a Fund’s Actual Portfolio and to minimize intra-day misalignment between the performance of the Proxy Portfolio and the performance of the Actual Portfolio. The Proxy Portfolio is designed to reflect the economic exposures and the risk characteristics of the Actual Portfolio on any given trading day.

Construction of a Proxy Portfolio that replicates the daily performance of the Actual Portfolio is achieved by performing a factor model analysis of a Fund’s Actual Portfolio. The factor model is comprised of three sets of factors or analytical metrics: market-based factors, fundamental factors, and industry/sector factors. Each Fund will have a universe of securities (the “Model Universe”) that will be used to generate the Fund’s Proxy Portfolio. The Model Universe will be comprised of securities that the Fund can purchase and will be a financial index or stated portfolio of securities from which Fund investments will be selected. The results of the factor model analysis of a Fund’s Actual Portfolio are then applied to a Fund’s Model Universe of securities, resulting in the generation of a Proxy Portfolio, which consists of a subset of the securities in the Model Universe. The Proxy Portfolio is designed to perform in a manner substantially identical to the performance of the Actual Portfolio. The Proxy Portfolio will only include securities and investments in which a Fund may invest. However, while the Proxy Portfolio and the Actual Portfolio will likely hold some or many of the same securities, the Proxy Portfolio and a Fund’s Actual Portfolio will not include identical securities. The Proxy Portfolio will be reconstituted daily.

Proxy Portfolio Disclosures

The composition of the Proxy Portfolio will be published on the Funds’ website at www.nuveen.com/etf each Business Day and will include the following information for each portfolio holding in the Proxy Portfolio: (1) ticker symbol; (2) CUSIP or other identifier; (3) description of holding; (4) quantity of each security or other asset held; and (5) percentage weight of the holding in the Proxy Portfolio. The Funds’ website will publish on a daily basis, per share for each Fund, the prior Business Day’s NAV and the Closing Price or Bid/Ask Price (each as defined below), and a calculation of the premium or discount of the Closing Price or Bid/Ask Price against such NAV. The Funds’ website will also publish other information metrics regarding the relative behavior of the Proxy Portfolio and the Actual Portfolio, including the Proxy Overlap (defined below). Additional information about how the Proxy Portfolio and the Proxy Overlap are calculated can be found in the SAI and on the Funds’ website at www.nuveen.com/etf. The website will also include Tracking Error for each Fund and, once a Fund has completed a fiscal year, the median bid/ask spread (expressed as a percentage rounded to the nearest hundredth), will be computed by identifying the Fund’s National Best Bid and Offer as of the end of each ten second interval during each trading day of the last thirty calendar days, dividing the difference between each such bid and offer by the midpoint of the


Section 4 Investing in the Funds	49

National Best Bid and Offer and identifying the median of these values. Additionally, the Funds are required to disclose on their website a table showing the number of days the Funds’ shares traded at a premium or discount and a line graph showing the Funds’ share premiums or discounts during the most recently completed calendar year and the most recently completed calendar quarters since that year (or the life of the Funds).

The Funds believe that the Proxy Portfolio Disclosures will enable Authorized Participants and other market makers to use the component securities and their weightings of the Proxy Portfolio to calculate intraday values that approximate the value of the securities in the Actual Portfolio and, based thereon, assess whether the market price of a Fund’s shares is higher or lower than the approximate contemporaneous value of the Actual Portfolio. These activities are intended to facilitate an arbitrage mechanism that keeps market prices of a Fund’s shares at or close to a Fund’s NAV. Moreover, the Proxy Portfolio Disclosures generated by the Proxy Portfolio methodology are intended to facilitate effective hedging activities by market makers, so that share market price bid/ask spreads will be narrow.

Below are some definitions of the defined terms used above:

· Closing Price – the official closing price of a Fund’s shares on a Fund’s primary listing exchange.

· Bid/Ask Price – the midpoint of the highest bid and the lowest offer based upon the National Best Bid and Offer as of the time of calculation of a Fund’s NAV.

· National Best Bid and Offer – the current national best bid and national best offer as disseminated by the Consolidated Quotation System or UTP Plan Securities Information Processor.

· Proxy Overlap – the percentage weight overlap between the holdings of the prior Business Day’s Proxy Portfolio compared to the Actual Portfolio’s holdings that formed the basis for a Fund’s calculation of NAV at the end of the prior Business Day. The Proxy Overlap is calculated based on the Proxy Portfolio and portfolio holdings as of the prior Business Day. The Proxy Overlap is calculated by taking the lesser weight of each asset held in common between the Actual Portfolio and the Proxy Portfolio and adding the totals. Additional information about how the Proxy Overlap is calculated can be found on a Fund’s website at www.nuveen.com/etf. Each Fund publishes the Proxy Overlap before the opening of Fund share trading each Business Day.

· Tracking Error – The standard deviation over the past three months of the daily proxy spread (i.e., the difference, in percentage terms, between the Proxy Portfolio per share NAV and that of the Actual Portfolio at the end of the trading day). Each Fund calculates its Tracking Error at the end of each trading day and publishes the Tracking Error before the opening of Fund share trading each Business Day.

Purchase and Redemption of Creation Units

Only certain institutional investors (typically market makers or other broker-dealers) who have entered into agreements with Nuveen Securities, LLC, the Funds’ distributor (the “Distributor”) (i.e., Authorized Participants), may purchase and redeem shares directly from the Funds at NAV and only in large blocks of shares or multiples thereof (“Creation Units”). Except when aggregated in Creation Units, shares are not redeemable by a Fund. An Authorized Participant must be either a DTC participant or a member of the Continuous Net Settlement System of the National Securities Clearing Corporation (“NSCC”).

Orders from Authorized Participants to create or redeem Creation Units may only be placed on a Business Day and are subject to approval by the Distributor. The names and quantities of the instruments that constitute the basket of securities in exchange for which a Fund issues or redeems shares will be the same as a Fund's Proxy Portfolio, except to the extent purchases and redemptions are made entirely or in part on a cash

Dividends and Distributions

Each Fund may earn interest from its investments in common stocks. These amounts, net of expenses and taxes (if applicable), are passed along to Fund shareholders as dividends. Dividends, if any, are declared and paid quarterly for the Nuveen Dividend Growth ETF and annually for all other ETFs in this prospectus.

Your broker is responsible for distributing any dividends and capital gain distributions to you.

Taxes and Tax Reporting

Early in each year, you will receive a statement from the firm through which you hold your Fund shares detailing the amount and nature of all distributions that you were paid

during the prior year. The tax status of your distributions is the same whether you reinvest them or elect to receive them in cash.

When seeking to satisfy redemption requests in whole or in part on a cash basis, a Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. This may cause a Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, a Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process were used. A Fund may be required to sell certain securities from its Actual Portfolio, including to the extent the composition of the Actual Portfolio differs from that of the Proxy Portfolio, prior to effecting an in-kind redemption to ensure it distributes the proper securities to Authorized Participants. Any such sales may generate taxable gain or loss.

The Funds are a series of Nushares ETF Trust, whose Investment Company Act file number is 811-23161.

NPR-GROW-0223P

Each Fund is a diversified series of the Trust, an open-end management investment company organized as a Massachusetts business trust on February 20, 2015. Each series of the Trust represents shares of beneficial interest in a separate portfolio of securities and other assets, with its own objective and policies. Each Fund is an exchange-traded fund (“ETF”) within the Nuveen family of ETFs (the “Nuveen ETFs”). The investment objective of each Fund is to track the investment results, before fees and expenses, of its underlying index (each, an “Index” and, collectively, the “Indexes”). Each Fund’s investment adviser is Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”). Each Fund’s sub-adviser is Teachers Advisors, LLC (“TAL” or the “Sub-Adviser”). The Adviser has agreed to pay all organizational and offering expenses of the Trust.

Each Fund issues and redeems shares at its net asset value per share (“NAV”) only in large block aggregations of a specified number of shares (“Creation Units”). Only certain institutional investors who have entered into agreements with the Funds’ distributor (“Authorized Participants”) may purchase and redeem shares directly from the Funds at NAV. Except when aggregated in Creation Units, shares of the Funds are not redeemable securities. See “Purchase and Redemption of Creation Units” later in this SAI for more information.

Each Fund intends to qualify each year for treatment as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), so that it will not be subject to federal income tax on income and gains that are timely distributed to Fund shareholders. Each Fund invests its assets, and otherwise conducts its operations, in a manner that is intended to satisfy the qualifying income, diversification and distribution requirements necessary to establish and maintain eligibility for such treatment.

An investment in the Funds should be made with an understanding that the value of the Funds’ portfolio securities may fluctuate in accordance with changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular security or issuer and changes in general economic or political conditions. The Funds may not outperform other investment strategies over short- or long-term market cycles and the Funds may decline in value. The Funds’ shares may trade above or below their NAV. An investor in the Funds could lose money over short or long periods of time. The price of the securities and other investments held by the Funds and thus the value of the Funds’ portfolios are expected to fluctuate in accordance with general economic conditions, interest rates, political events, and other factors.

Investor perceptions may also impact the value of each Fund’s investments and the value of an investment in each Fund’s shares. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic, public health or banking crises. Issuer-specific conditions may also affect the value of a Fund’s investments. The financial condition of an issuer of a security or counterparty to a contract may cause it to default or become unable to pay interest or principal due on the security or contract. The Funds cannot collect interest and principal payments if the issuer or counterparty defaults. Accordingly, the value of an investment in a Fund may change in response to issuer or counterparty defaults and changes in the credit ratings of a Fund’s portfolio securities.

Although the Funds attempt to invest in liquid securities and instruments, there can be no guarantee that a liquid market for such securities and instruments will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of a Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

The method by which Creation Units are created and Fund shares are subsequently traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Trust on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “1933 Act”), may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if, after placing an order for Creation Units with Nuveen Securities, LLC (“Nuveen Securities” or the “Distributor”), the broker-dealer or its client breaks them down into constituent shares and sells such shares directly to customers, or if the broker-dealer or its client chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the Investment Company Act of 1940, as amended (the “1940 Act”). Firms that incur a prospectus-delivery obligation with respect to shares of a Fund are reminded that pursuant to Rule 153 under the 1933 Act, a prospectus-delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange is satisfied by the fact that the Fund’s Prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

In addition to the investment objectives and policies set forth in the Prospectus and under “Investment Policies and Techniques” below, each Fund is subject to the investment restrictions set forth below. The investment restrictions set forth in numbers (1) through (7) below are fundamental and cannot be changed with respect to a Fund without approval by the holders of a majority of the outstanding shares of the Fund as defined in the 1940 Act, i.e., by the lesser of the vote of (a) 67% of the shares of the Fund present at a meeting where more than 50% of the outstanding shares are present in person or by proxy, or (b) more than 50% of the outstanding shares of the Fund.

(1) Concentrate its investments in a particular industry or group of industries, as the term “concentrate” is used in the 1940 Act, except that the Fund may concentrate its investments in a particular industry or group of industries to approximately the same extent that the Index concentrates in a particular industry or group of industries.

Each Fund, except the Nuveen ESG Dividend ETF and Nuveen ESG Large-Cap ETF, may not:

(1) Concentrate its investments in a particular industry, as the term “concentrate” is used in the 1940 Act, except as may be necessary to approximate the composition of its Index.

(2) Borrow money or issue senior securities, except as permitted under the 1940 Act, as interpreted or modified from time to time by any regulatory authority having jurisdiction.

(3) With respect to 75% of its total assets, purchase securities of an issuer (other than (i) securities issued by other investment companies, (ii) securities issued by the U.S. government, its agencies, instrumentalities or authorities, or (iii) repurchase agreements fully collateralized by U.S. government securities) if (a) such purchase would, at the time, cause more than 5% of the Fund’s total assets taken at market value to be invested in the securities of such issuer; or (b) such purchase would, at the time, result in more than 10% of the outstanding voting securities of such issuer being held by the Fund.

(4) Purchase or sell physical commodities, unless acquired as a result of ownership of securities or other instruments; but this restriction shall not prohibit the Fund from investing in options on commodity indices, commodity futures contracts and options thereon, commodity-related swap agreements, other commodity-related derivative instruments, and investment companies that provide exposure to commodities.

(5) Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments; but this restriction shall not prevent the Fund from purchasing or selling securities or other instruments backed by real estate or interests therein or of issuers engaged in real estate activities.

(6) Act as an underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the 1933 Act in connection with the purchase and sale of portfolio securities.

(7) Make loans, except as permitted under the 1940 Act, as interpreted or modified from time to time by any regulatory authority having jurisdiction.

Except with respect to the limitation set forth in number (2) above, the foregoing restrictions and limitations will apply only at the time of purchase of securities, and the percentage limitations will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities, unless otherwise indicated.

For purposes of applying the limitation set forth in number (1) above, according to the current interpretation by the Securities and Exchange Commission (the “SEC”), a Fund would be concentrated in an industry if 25% or more of its net assets, based on current market value at the time of purchase, were invested in that industry. To the extent a Fund invests in other investment companies, it will consider the investments of the underlying investment companies when determining compliance with the limitation set forth in number (1) above, to the extent the Fund has sufficient information about such investments. For purposes of this limitation, issuers of the following securities will not be considered to be members of any industry: securities of the U.S. government and its agencies or instrumentalities; except as set forth in the following sentence, securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. To the extent that the income from a municipal bond is derived principally from a specific project or backed principally from the assets and revenue of a non-governmental user, the securities will be deemed to be from the industry of that project or user.

Each foreign government will be considered to be a member of a separate industry.

For purposes of applying the limitations set forth in number (2) above, under the 1940 Act as currently in effect, a Fund is not permitted to issue senior securities, except that a Fund may borrow from any bank if immediately after such borrowing the value of a Fund’s total assets is at least 300% of the principal amount of all of a Fund’s borrowings (i.e., the principal amount of the borrowings may not exceed 33 1/3% of a Fund’s total assets). In the event that such asset coverage shall at any time fall below 300%, a Fund shall, within three calendar days thereafter (not including Sundays and holidays), reduce the amount of its borrowings to an extent that the asset coverage of such borrowing shall be at least 300%.

For purposes of applying the limitations set forth in number (7) above, there are no limitations with respect to unsecured loans made by a Fund to an unaffiliated party. However, if a Fund loans its portfolio securities, the obligation on the part of the Fund to return collateral upon termination of the loan could be deemed to involve the issuance of a senior security within the meaning of Section 18(f) of the 1940 Act. In order to avoid violation of Section 18(f), a Fund may not make a loan of portfolio securities if, as a result, more than one-third of its total asset value (at market value computed at the time of making a loan) would be on loan.

In addition to the foregoing fundamental investment policies, each Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Funds’ Board of Trustees (the “Board”) without a shareholder vote.

(1) Acquire any securities of registered open-end investment companies or registered unit investment trusts in reliance on subparagraph (F) or subparagraph (G) of Section 12(d)(1) of the 1940 Act.

(2) Invest directly in futures, options on futures and swaps to the extent that the Adviser would be required to register with the Commodity Futures Trading Commission (“CFTC”) as a commodity pool operator. See “Investment Policies and Techniques—Derivatives—Limitations on the Use of CFTC-Regulated Futures, Options on Futures and Swaps.”

Each Fund has adopted a non-fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (the “Name Policy”) whereby the Fund, under normal market conditions, will (i) invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of its Index and, (ii) for each Fund except for Nuveen ESG Dividend ETF, invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in companies with market capitalizations suggested by the Fund’s name. As a result, each of these Funds must provide shareholders with a notice, meeting the requirements of Rule 35d-1(c), at least 60 days prior to any change of its Name Policy. For purposes of the Name Policy, each Fund may consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, the Funds will value eligible derivatives at fair value or market value instead of notional value. If, subsequent to an investment, the 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

The following information supplements the discussion of the Funds’ investment objectives, principal investment strategies, policies and techniques that appears in the Prospectus for the Funds. Additional information concerning principal investment strategies of the Funds, and other investment strategies that may be used by the Funds, are set forth below in alphabetical order.

If a percentage limitation on investments by a Fund stated in this SAI or the Prospectus is adhered to at the time of an investment, a later increase or decrease in percentage resulting from changes in asset value will not be deemed to violate the limitation except in the case of the limitations on borrowing. In connection with the Fund’s investment restrictions, any reference in this SAI or the Prospectus to a specific rating encompasses all gradations of that rating (e.g., if this SAI or the Prospectus states that a fund may invest in securities rated as low as B, the fund may invest in securities rated B-).

References in this section to the Adviser also apply, to the extent applicable, to the Sub-Adviser of the Funds.

Each Fund may hold assets in cash or cash equivalents, money market funds and short-term taxable fixed income securities in such proportions as warranted by prevailing market conditions and the Fund’s principal investment strategies. Each Fund may only invest in short-term taxable fixed income securities with a maturity of one year or less and whose issuers have a long-term rating of at least A- or higher by Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc. (“Standard & Poor’s”), A3 or higher by Moody’s Investors Service, Inc. (“Moody’s”) or A- or higher by Fitch, Inc. (“Fitch”). Short-term taxable fixed income securities are defined to include, without limitation, the following:

(1) U.S. Government Securities. Each Fund may invest in U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association, whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. In addition, each Fund may invest in sovereign debt obligations of non-U.S. countries. U.S. Treasury obligations include separately traded interest and principal component parts of such obligations, known as Separately Traded Registered Interest and Principal Securities (“STRIPS”), which are transferable through the Federal book-entry system. STRIPS are sold as zero coupon securities, which means that they are sold at a substantial discount and redeemed at face value at their maturity date without interim cash payments of interest or principal. This discount is accreted over the life of the security, and such accretion will constitute the income earned on the security for both accounting and tax purposes. Because of these features, such securities may be subject to greater interest rate volatility than interest paying U.S. Treasury obligations.

(2) Certificates of Deposit. Each Fund may invest in certificates of deposit issued against funds deposited in a bank or savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. If such certificates of deposit are non-negotiable, they will be considered illiquid investments and be subject to the Fund’s 15% restriction on investments in illiquid investments. Pursuant to the certificate of deposit, the issuer agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current FDIC regulations, the maximum insurance payable as to any one certificate of deposit is $250,000; therefore, certificates of deposit purchased by a Fund may not be fully insured.

(3) Bankers’ Acceptances. Each Fund may invest in bankers’ acceptances, which are short-term credit instruments used to finance commercial transactions. Generally, an acceptance is a time draft drawn on a bank by an exporter or an importer to obtain a stated amount of funds to pay for specific merchandise. The draft is then “accepted” by a bank that, in effect, unconditionally guarantees to pay the face value of the instrument on its maturity date. The acceptance may then be held by the accepting bank as an asset or it may be sold in the secondary market at the going rate of interest for a specific maturity.

(4) Repurchase Agreements. Each Fund may invest in repurchase agreements which involve purchases of debt securities. In such an action, at the time the Fund purchases the security, it simultaneously agrees to resell and redeliver the security to the seller, who also simultaneously agrees to buy back the security at a fixed price and time. This assures a predetermined yield for the Fund during its holding period since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to certain obligations. Collateral may consist of any fixed income security which is an eligible investment for the Fund. The Fund’s custodian will hold the securities underlying any repurchase agreement, or the securities will be part of the Federal Reserve/Treasury Book Entry System. The market value of the collateral underlying the repurchase agreement will be determined on each business day. If at any time the market value of the collateral falls below the repurchase price under the repurchase agreement (including any accrued interest), the Fund will promptly receive additional collateral (so the total collateral is an amount at least equal to the repurchase price plus accrued interest). Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in

the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, however, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. The portfolio managers monitor the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. The portfolio managers do so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(5) Bank Time Deposits. Each Fund may invest in bank time deposits, which are monies kept on deposit with banks or savings and loan associations for a stated period of time at a fixed rate of interest. There may be penalties for the early withdrawal of such time deposits, in which case the yields of these investments will be reduced.

(6) Commercial Paper. Each Fund may invest in commercial paper, which are short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for the notes. However, they are redeemable by the Fund at any time. The portfolio managers will consider the financial condition of the corporation (e.g., earning power, cash flow and other liquidity ratios) and will continuously monitor the corporation’s ability to meet all of its financial obligations, because the Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. A Fund may purchase commercial paper consisting of issues rated at the time of purchase within the two highest rating categories by Standard & Poor’s, Fitch or Moody’s, or which have been assigned an equivalent rating by another nationally recognized statistical rating organization.

(7) Eurodollar and Yankee Instruments. Each Fund may invest in Eurodollar certificates of deposit issued by foreign branches of U.S. or foreign banks; Eurodollar time deposits, which are U.S. dollar-denominated deposits in foreign branches of U.S. or foreign banks; and Yankee certificates of deposit, which are U.S. dollar-denominated certificates of deposit issued by U.S. branches of foreign banks and held in the United States. In each instance, a Fund may only invest in bank instruments issued by an institution which has capital, surplus and undivided profits of more than $100 million or the deposits of which are insured by the Bank Insurance Fund or the Savings Association Insurance Fund.

(8) Money Market Funds and Short-Term Debt Funds. Each Fund may invest in money market funds. A Fund will bear its proportionate share of the money market fund’s fees and expenses (see “Other Investment Companies and Other Pooled Investment Vehicles” below). A Fund may hold securities of other mutual funds that invest primarily in debt obligations with remaining maturities of 13 months or less.

(9) Variable Amount Master Demand Notes. Each Fund may invest in variable amount master demand notes, which are unsecured demand notes that permit the indebtedness thereunder to vary and provide for periodic adjustments in the interest rate according to the terms of the instrument. Because master demand notes are direct lending arrangements between a Fund and the issuer, they are not normally traded. Although there is no secondary market in the notes, a Fund may demand payment of principal and accrued interest at any time. While the notes are not typically rated by credit rating agencies, issuers of variable amount master demand notes (which are normally manufacturing, retail, financial, and other business concerns) must satisfy the same criteria as set forth above for commercial paper. The Sub-Adviser will consider the earning power, cash flow and other liquidity ratios of the issuers of such notes and will continuously monitor their financial status and ability to meet payment on demand.

Subject to the limitations set forth below under “Limitations on the Use of CFTC-Regulated Futures, Options on Futures and Swaps,” each Fund may use derivative instruments as described below. Generally, a derivative is a financial contract the value of which depends upon, or is derived from, the value of an underlying asset, reference rate or index. Derivatives generally take the form of contracts under which the parties agree to payments between them based upon the performance of a wide variety

of underlying references, such as stocks, bonds, loans, commodities, interest rates, currency exchange rates, and various domestic and foreign indices.

A Fund may use derivatives for a variety of reasons, including as a substitute for investing directly in securities, as part of a hedging strategy (that is, for the purpose of reducing risk to the Fund), or for other purposes related to the management of the Fund. Derivatives permit a Fund to increase or decrease the level of risk, or change the character of the risk, to which its portfolio is exposed in much the same way as the Fund can increase or decrease the level of risk, or change the character of the risk, of its portfolio by making investments in specific securities. However, derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on a Fund’s performance.

While transactions in some derivatives may be effected on established exchanges, many other derivatives are privately negotiated and entered into in the over-the-counter (“OTC”) market with a single counterparty. When exchange-traded derivatives are purchased and sold, a clearing agency associated with the exchange stands between each buyer and seller and effectively guarantees performance of each contract, either on a limited basis through a guaranty fund or to the full extent of the clearing agency’s balance sheet. Transactions in OTC derivatives not subject to a clearing requirement have no such protection. Each party to an uncleared OTC derivative bears the risk that its direct counterparty will default. In addition, OTC derivatives are generally less liquid than exchange-traded derivatives because they often can only be closed out with the other party to the transaction.

The particular derivative instruments a Fund can use are described below. A Fund’s portfolio managers may decide not to employ some or all of these instruments, and there is no assurance that any derivatives strategy used by a Fund will succeed. A Fund may employ new derivative instruments and strategies when they are developed, if those investment methods are consistent with the Fund’s investment objective and are permissible under applicable regulations governing the Fund.

Each Fund may purchase put and call options on specific securities (including groups or “baskets” of specific securities), stock indices, and/or foreign currencies. In addition, a Fund may write put and call options on such financial instruments.

Options on Securities. Each Fund may purchase put and call options on securities. A put option on a security gives the purchaser of the option the right (but not the obligation) to sell, and the writer of the option the obligation to buy, the underlying security at a stated price (the “exercise price”) at any time before the option expires. A call option on a security gives the purchaser the right (but not the obligation) to buy, and the writer the obligation to sell, the underlying security at the exercise price at any time before the option expires. The purchase price for a put or call option is the “premium” paid by the purchaser for the right to sell or buy.

A Fund may purchase put options to hedge against a decline in the value of its portfolio. By using put options in this way, a Fund would reduce any profit it might otherwise have realized in the underlying security by the amount of the premium paid for the put option and by transaction costs. In similar fashion, a Fund may purchase call options to protect against an increase in the price of securities that a Fund anticipates purchasing in the future, a practice sometimes referred to as “anticipatory hedging.” The premium paid for the call option plus any transaction costs will reduce the benefit, if any, realized by a

Fund upon exercise of the option, and, unless the price of the underlying security rises sufficiently, the option may expire unexercised.

Options on Interest Rates and Indices. Each Fund may purchase put and call options on interest rates and bond indices. An option on interest rates or on an index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing value of the underlying interest rate or index is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. This amount of cash is equal to the difference between the exercise-settlement value of the interest rate option or the closing price of the index and the exercise price of the option expressed in dollars times a specified multiple (the “multiplier”). The writer of the option is obligated, for the premium received, to make delivery of this amount. Settlements for interest rate and index options are always in cash.

Options on Currencies. Each Fund may purchase put and call options on foreign currencies. A foreign currency option provides the option buyer with the right to buy or sell a stated amount of foreign currency at the exercise price at a specified date or during the option period. A call option gives its owner the right, but not the obligation, to buy the currency, while a put option gives its owner the right, but not the obligation, to sell the currency. The option seller (writer) is obligated to fulfill the terms of the option sold if it is exercised. However, either seller or buyer may close its position during the option period in the secondary market for such options at any time prior to expiration.

A foreign currency call option rises in value if the underlying currency appreciates. Conversely, a foreign currency put option rises in value if the underlying currency depreciates. While purchasing a foreign currency option may protect the Fund against an adverse movement in the value of a foreign currency, it would limit the gain which might result from a favorable movement in the value of the currency. For example, if a Fund were holding securities denominated in an appreciating foreign currency and had purchased a foreign currency put to hedge against a decline in the value of the currency, it would not have to exercise its put. In such an event, however, the amount of the Fund’s gain would be offset in part by the premium paid for the option. Similarly, if a Fund entered into a contract to purchase a security denominated in a foreign currency and purchased a foreign currency call to hedge against a rise in the value of the currency between the date of purchase and the settlement date, the Fund would not need to exercise its call if the currency instead depreciated in value. In such a case, the Fund could acquire the amount of foreign currency needed for settlement in the spot market at a lower price than the exercise price of the option.

Writing Options. The Funds may write (sell) put and call options. These transactions would be undertaken principally to produce additional income. A Fund receives a premium from writing options which it retains whether or not the option is exercised. The Funds may write straddles consisting of a combination of a call and a put written on the same underlying instrument.

A Fund will write a call option on a security only if (a) the Fund owns the security underlying the call, (b) the Fund has an absolute and immediate right to acquire that security without additional cash consideration (or, if additional cash consideration is required, cash or other liquid assets in such amount are segregated), or (c) the Fund holds a call on the same security where the exercise price of the call is (i) equal to or less than the exercise price of the call written, or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated liquid assets.

A Fund will write a call option on a basket of securities, an index or currency only if (a) the Fund segregates liquid assets in an amount equal to the contract value of the index, basket or currency, or (b) the Fund holds a call on the same index, basket or currency as the call written where the exercise price of the call held is (i) equal to or less than the exercise price of the call written, or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated liquid assets.

A Fund will write a put option on a security, basket of securities, index or currency only if (a) the Fund segregates liquid assets equal to the exercise price or (b) the Fund holds a put on the same security, basket of securities, index or currency as the put written where the exercise price of the put held is (i) equal to or greater than the exercise price of the put written, or (ii) less than the exercise price of the put written, provided the difference is maintained by the Fund in segregated liquid assets.

When a Fund writes a straddle, sufficient assets will be segregated to meet the Fund’s immediate obligations. A Fund may segregate the same liquid assets for both the call and put options in a straddle where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put. In such cases, the Fund will also segregate liquid assets equivalent to the amount, if any, by which the put is “in the money.”

Expiration or Exercise of Options. If an option purchased by a Fund expires unexercised, the Fund realizes a capital loss equal to the premium paid. If an option written by a Fund expires unexercised, the Fund realizes a capital gain equal to the premium received at the time the option was written. Prior to the earlier of exercise or expiration, an exchange traded option may be closed out by an offsetting purchase or sale of an option of the same series (type, exchange, underlying security, currency or index, exercise price, and expiration). There can be no assurance, however, that a closing purchase or sale transaction can be effected when a Fund desires.

The Funds may sell put or call options it has previously purchased, which could result in a net gain or loss depending on whether the amount realized on the sale is more or less than the premium and other transaction costs paid on the put or call option which is sold. Prior to exercise or expiration, an option may be closed out by an offsetting purchase or sale of an option of the same series. A Fund will realize a capital gain from a closing purchase transaction if the cost of the closing option is less than the premium received from writing the option, or, if it is more, the Fund will realize a capital loss. If the premium received from a closing sale transaction is more than the premium paid to purchase the option, the Fund will realize a capital gain or, if it is less, the Fund will realize a capital loss. The principal factors affecting the market value of a put or a call option include supply and demand, interest rates, the current market price of the underlying security, currency or index in relation to the exercise price of the option, the volatility of the underlying security, currency or index, and the time remaining until the expiration date.

Each Fund may engage in futures transactions. A Fund may buy and sell futures contracts that relate to (1) interest rates, (2) foreign currencies, (3) debt securities, and (4) bond indices. A Fund may only enter into futures contracts which are standardized and traded on a U.S. or foreign exchange, board of trade or similar entity, or quoted on an automated quotation system.

A futures contract is an agreement between two parties to buy and sell a security, interest rate or currency (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract. Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Unlike when a Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract. Initially, a Fund will be required to deposit with its futures broker (also known as a futures commission merchant (“FCM”)) an amount of cash or securities equal to a specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, FCMs may establish margin deposit requirements that are higher than the exchange minimums. Cash held as margin is generally invested by the FCM in high-quality instruments permitted under CFTC regulations, with returns retained by the FCM and interest paid to the Fund on the cash at an agreed-upon rate. A Fund will also receive any interest paid from coupon-bearing securities, such as Treasury securities, held in margin accounts. Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by a Fund as unrealized gains or losses. At any time prior to expiration of the futures contract, a Fund may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of a Fund, the Fund may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Fund. Futures transactions also involve brokerage costs.

made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

Each Fund may enter into forward currency contracts. A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are traded directly between currency traders (usually large commercial banks) and their customers. Unlike futures contracts, which are standardized contracts, forward contracts can be specifically drawn to meet the needs of the parties that enter into them. The parties to a forward currency contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated exchange. Because forward contracts are not traded on an exchange, a Fund is subject to the credit and performance risk of the counterparties to such contracts.

Each Fund may enter into interest rate, total return, and credit default swap agreements.

The Funds may enter into swap transactions for any purpose consistent with its investment objectives and strategies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, to protect against an increase in the price of securities the Fund anticipates purchasing at a later date, to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain securities, reference rates, sectors or markets.

Interest Rate Swaps. Interest rate swaps are financial instruments that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future. Some of the different types of interest rate swaps are “fixed-for floating rate swaps,” “termed basis swaps” and “index amortizing swaps.” Fixed-for floating rate swaps involve the exchange of fixed interest rate cash flows for floating rate cash flows. Termed basis swaps entail cash flows to both parties based on floating interest rates, where the interest rate indices are different. Index amortizing swaps are typically fixed-for floating swaps where the notional amount changes if certain conditions are met. Like a traditional investment in a debt security, a Fund could lose money by investing in an interest rate swap if interest rates change adversely.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with bonds and defined baskets of loans and mortgages. A Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely-diversified range of securities in a single trade. An index total return swap can be used by the portfolio managers to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. A Fund may enter into credit default swap agreements either as a buyer or a seller. The Fund may buy protection to attempt to mitigate the risk of default or credit quality deterioration in one or more of its individual holdings or in a segment of the fixed income securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Fund may sell protection in an attempt to gain exposure to

the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments.

As the buyer of protection in a credit default swap, the Fund will pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

If a Fund is a seller of protection in a credit default swap and no credit event occurs, the Fund would generally receive an up-front payment or a periodic stream of payments over the term of the swap. If a credit event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Fund effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. Thus, the Fund bears the same risk as it would by buying the reference obligations directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “Risks Associated with Swap Transactions.”

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. A Fund may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Fund generally will incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when a Fund writes a swap option, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If the Sub-Adviser is incorrect in its forecasts of default risks, market spreads or other applicable factors the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, a Fund effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The Fund may only close out a swap or other two-party contract with its particular counterparty, and may only transfer a position with the consent of that counterparty. In addition, the price at which the Fund may close out such a two party contract may not correlate with the price change in the underlying reference asset. If the counterparty defaults, the Fund will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Fund will succeed in enforcing its rights. It also is possible that developments in the derivatives market, including potential government regulation, could adversely affect a Fund’s ability to terminate existing swap or other agreements or to realize amounts to be received under such agreements.

Each Fund may enter into interest rate caps, floors, and collars. Caps and floors have an effect similar to buying or writing options. In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed-upon level. The seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed-upon level. An interest rate collar involves selling a cap and purchasing a floor or vice versa to protect a Fund against interest rate movements exceeding given minimum or maximum levels.

Each Fund will limit its direct investments in CFTC-regulated futures, options on futures and swaps (“CFTC Derivatives”) to the extent necessary for the Adviser to claim the exclusion from regulation as a commodity pool operator with respect to each of the Funds under CFTC Rule 4.5, as such rule may be amended from time to time. Under Rule 4.5 as currently in effect, each Fund will limit its trading activity in CFTC Derivatives (excluding activity for “bona fide hedging purposes,” as defined by the CFTC) such that it meets one of the following tests:

· Aggregate initial margin and premiums required to establish its positions in CFTC Derivatives do not exceed 5% of the liquidation value of the Fund’s portfolio, after taking into account unrealized profits and losses on such positions; or

· Aggregate net notional value of its positions in CFTC Derivatives does not exceed 100% of the liquidation value of the Fund’s portfolio, after taking into account unrealized profits and losses on such positions.

With respect to each Fund, the Adviser has filed a notice of eligibility for exclusion from the definition of the term commodity pool operator under the Commodity Exchange Act and therefore is not subject to registration or regulation as a commodity pool operator thereunder.

The requirements for qualification as a regulated investment company may also limit the extent to which a Fund may invest in CFTC Derivatives. See “Tax Matters—Qualification as a Regulated Investment Company.”

Each Fund’s transactions in futures contracts and options will be subject to special provisions of the Code, that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital, or short-term or long-term), may accelerate recognition of income to the Fund and may defer Fund losses. These rules could, therefore, affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out) and (b) may cause the Fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the 90% distribution requirement for qualifying to be taxed as a regulated investment company and the distribution requirement for avoiding excise taxes.

The use of derivative instruments involves certain general risks and considerations as described below.

(1) Market Risk. Market risk is the risk that the value of the underlying assets may go up or down. Adverse movements in the value of an underlying asset can expose a Fund to losses. The successful use of derivative instruments depends upon a variety of factors, particularly the portfolio managers’ ability to predict movements in the relevant markets, which may require different skills than predicting changes in the prices of individual securities. There can be no assurance that any particular strategy adopted will succeed.

(2) Counterparty Risk. Counterparty risk is the risk that a loss may be sustained as a result of the failure of a counterparty to comply with the terms of a derivative instrument. The counterparty risk for exchange-traded derivatives is generally less than for OTC derivatives, since generally a clearing agency, which is the issuer or counterparty to each exchange-traded instrument, provides a guarantee of performance. For many OTC instruments, there is no similar clearing agency guarantee. In all transactions, a Fund will bear the risk that the counterparty will default, and this could result in a loss of the expected benefit of the derivative transactions and possibly other losses to the Fund. Each Fund will enter into derivatives transactions only with counterparties that its portfolio managers reasonably believe are capable of performing under the contract.

remains unchanged with any change in the price of the underlying asset. With an imperfect hedge, the value of the derivative instrument and its hedge are not perfectly correlated. For example, if the value of a derivative instrument used in a short hedge (such as a CDS) increased by less than the decline in value of the hedged investments, the hedge would not be perfectly correlated. This might occur due to factors unrelated to the value of the investments being hedged, such as speculative or other pressures on the markets in which these instruments are traded. The effectiveness of hedges using instruments on indices will depend, in part, on the degree of correlation between price movements in the index and the price movements in the investments being hedged.

(5) Legal Risk. Legal risk is the risk of loss caused by the unenforceability of a party’s obligations under the derivative. While a party seeking price certainty agrees to surrender the potential upside in exchange for downside protection, the party taking the risk is looking for a positive payoff. Despite this voluntary assumption of risk, a counterparty that has lost money in a derivative transaction may try to avoid payment by exploiting various legal uncertainties about certain derivative products.

(6) Systemic or “Interconnection” Risk. Systemic or interconnection risk is the risk that a disruption in the financial markets will cause difficulties for all market participants. In other words, a disruption in one market will spill over into other markets, perhaps creating a chain reaction. Much of the OTC derivatives market takes place among the OTC dealers themselves, thus creating a large interconnected web of financial obligations. This interconnectedness raises the possibility that a default by one large dealer could create losses for other dealers and destabilize the entire market for OTC derivative instruments.

(7) Leverage Risk. Leverage risk is the risk that a Fund may be more volatile than if it had not been leveraged due to leverage’s tendency to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The use of leverage may also cause a Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements.

(8) Regulatory Risk. The Dodd-Frank Act Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) has initiated a dramatic revision of the U.S. financial regulatory framework and covers a broad range of topics, including (among many others) a reorganization of federal financial regulators; a process intended to improve financial systemic stability and the resolution of potentially insolvent financial firms; and new rules for derivatives trading. In particular, the Dodd-Frank Act makes broad changes to the OTC derivatives market, grants significant new authority to the SEC and the CFTC to regulate OTC derivatives and market participants, and will require clearing and exchange trading of many OTC derivatives transactions. New requirements, such as capital requirements and mandatory clearing of OTC derivatives transactions, have impacted and may continue to impact the costs to a fund of trading these instruments and, as a result, may affect returns to investors in a Fund. Instruments in which a Fund may invest, or the issuers of such instruments, may be affected by the new legislation and regulation in ways that are unforeseeable. Certain of the implementing regulations have not yet

been finalized or made effective. Accordingly, the ultimate impact of the Dodd-Frank Act, including on the derivative instruments in which a Fund may invest, is not yet certain.

Under normal market conditions, the Funds primarily invest in equity securities, which include common stocks, preferred securities, warrants to purchase common stocks or preferred securities, convertible securities, participatory notes, interests in real estate investment trusts, common and preferred units of master limited partnerships, and other securities with equity characteristics.

Common stocks represent units of ownership in a company. Common stocks usually carry voting rights and earn dividends. Unlike preferred securities, dividends on common stocks are not prescribed in advance but are declared at the discretion of a company’s board.

While investing in stocks allows shareholders to participate in the benefits of owning a company, such shareholders must accept the risks of ownership. Unlike bondholders, who have preference to a company’s earnings and cash flow, common stockholders are entitled only to the residual amount after a company meets its other obligations. For this reason, the value of a company’s stock will usually react more strongly to actual or perceived changes in the company’s financial condition or prospects than its debt obligations. Stockholders of a company that fares poorly can lose money.

Stock markets tend to move in cycles with short or extended periods of rising and falling stock prices. The value of a company’s stock may fall because of:

· Factors that directly relate to that company, such as decisions made by its management or lower demand for the company’s products or services;

· Factors affecting an entire industry, such as increases in production costs; and

· Changes in financial market conditions that are relatively unrelated to the company or its industry, such as changes in interest rates, currency exchange rates or inflation rates.

An investment in common stocks of issuers with small or medium market capitalizations generally involves greater risk and price volatility than an investment in common stocks of larger, more established companies. This increased risk may be due to the greater business risks of their small or medium size, limited markets and financial resources, narrow product lines and frequent lack of management depth. The securities of small and medium capitalization companies are often traded in the over-the-counter market, and might not be traded in volumes typical of securities traded on a national securities exchange. Thus, the securities of small and medium capitalization companies are likely to be less liquid and subject to more abrupt or erratic market movements than securities of larger, more established companies.

Like common stocks, preferred securities are also units of ownership in a company, but preferred securities normally have preference over common stocks in the payment of dividends and the liquidation of the company. In all other respects, however, preferred securities are subordinated to the liabilities of the issuer. Unlike common stocks, preferred securities are generally not entitled to vote on corporate matters. Types of preferred securities include adjustable-rate preferred securities, fixed dividend preferred securities, perpetual preferred securities and sinking fund preferred securities. Generally, the market value of preferred securities with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk.

Because preferred securities are generally junior to most other forms of debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred security than in a more senior debt security with similar stated yield characteristics.

Each Fund may invest in warrants if, after giving effect thereto, not more than 5% of its net assets will be invested in warrants other than warrants acquired in units or attached to other securities. Investing in warrants is purely speculative in that they have no voting rights, pay no dividends, and have no rights with respect to the assets of the corporation issuing them. Warrants are issued by the issuer of a security and provide their holder the option to purchase that security upon the warrants’ exercise at a specific price for a specific period of time. They do not represent ownership of the securities but only the right to buy them. The prices of warrants do not necessarily parallel the prices of the underlying securities.

For issues where the conversion of the security is not at the option of the holder, a Fund may be required to convert the security into the underlying common stock even at times when the value of the underlying common stock or other equity security has declined substantially.

Convertible securities are hybrid securities that combine the investment characteristics of bonds and common stocks. Convertible securities typically consist of debt securities or preferred securities that may be converted within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. They also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Convertible securities entitle the holder to receive interest paid or accrued on debt, or dividends paid or accrued on preferred securities, until the security matures or is redeemed, converted or exchanged.

The market value of a convertible security generally is a function of its “investment value” and its “conversion value.” A security’s “investment value” represents the value of the security without its conversion feature (i.e., a comparable non-convertible fixed-income security). The investment value is determined by, among other things, reference to its credit quality and the current value of its yield to maturity or probable call date. At any given time, investment value is dependent upon such factors as the general level of interest rates, the yield of similar non-convertible securities, the financial strength of the issuer and the seniority of the security in the issuer’s capital structure. A security’s “conversion value” is determined by multiplying the number of shares the holder is entitled to receive upon conversion or exchange by the current price of the underlying security. If the conversion value of a convertible security is significantly below its investment value, the convertible security will trade like non-convertible debt or a preferred security in the sense that its market value will not be influenced greatly by fluctuations in the market price of the underlying security into which it can be converted. Instead, the convertible security’s price will tend to move in the opposite direction from interest rates. Conversely, if the conversion value of a convertible security is significantly above its investment value, the market value of the convertible security will be more heavily influenced by fluctuations in the market price of the underlying stock. In that case, the convertible security’s price may be as volatile as that of the common stock. Because both interest rate and market movements can influence its value, a convertible security is not generally as sensitive to interest rates as a similar fixed-income security, nor is it generally as sensitive to changes in share price as its underlying stock.

A Fund’s investments in convertible securities, particularly securities that are convertible into securities of an issuer other than the issuer of the convertible security, may be illiquid. A Fund’s investments in convertible securities may at times include securities that have a mandatory conversion feature, pursuant to which the securities convert automatically into common stock or other equity securities (of the same or a different issuer) at a specified date and a specified conversion ratio, or that are convertible at the option of the issuer. For issues where the conversion of the security is not at the option of the holder, a Fund may be required to convert the security into the underlying common stock even at times when the value of the underlying common stock or other equity security has declined substantially.

In addition, some convertible securities are often rated below investment-grade or are not rated, and therefore may be considered speculative investments. The credit rating of a company’s convertible securities is generally lower than that of its conventional debt securities. Convertible securities are normally considered “junior” securities—that is, the company usually must pay interest on its conventional corporate debt before it can make payments on its convertible securities. Some convertible securities are particularly sensitive to interest rate changes when their predetermined conversion price is much higher than the issuing company’s common stock.

normally associated with a direct investment in the underlying securities. In addition, participatory notes are subject to counterparty risk, which is the risk that the broker-dealer or bank that issues the notes will not fulfill its contractual obligation to complete the transaction with a Fund. Participatory notes constitute general unsecured, unsubordinated contractual obligations of the banks or broker-dealers that issue them, and a Fund is relying on the creditworthiness of such banks or broker-dealers and has no rights under a participatory note against the issuers of the securities underlying such participatory notes. There can be no assurance that the trading price or value of participatory notes will equal the value of the underlying value of the equity securities they seek to replicate.

Real estate investment trusts (“REITs”) are publicly traded corporations or trusts that specialize in acquiring, holding, and managing residential, commercial or industrial real estate located in the United States or foreign countries. A REIT is not taxed at the entity level on income distributed to its shareholders or unitholders if it distributes to shareholders or unitholders at least 90% of its taxable income for each taxable year and complies with regulatory requirements relating to its organization, ownership, assets and income.

REITs generally can be classified as equity REITs, mortgage REITs and hybrid REITs. An equity REIT invests the majority of its assets directly in real property and derives its income primarily from rents and from capital gains on real estate appreciation which are realized through property sales. A mortgage REIT invests the majority of its assets in real estate mortgage loans and services its income primarily from interest payments. A hybrid REIT combines the characteristics of an equity REIT and a mortgage REIT.

Investing in REITs would subject a Fund to risks associated with the real estate industry. The real estate industry has been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future. Real property values and income from real property may decline due to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, changes in zoning laws, casualty or condemnation losses, regulatory limitations on rents, changes in neighborhoods and in demographics, increases in market interest rates, or other factors. Factors such as these may adversely affect companies which own and operate real estate directly, companies which lend to such companies, and companies which service the real estate industry.

The Fund may also be subject to risks associated with direct investments in REITs. Equity REITs will be affected by changes in the values of and income from the properties they own, while mortgage REITs may be affected by the credit quality of the mortgage loans they hold. In addition, REITs are dependent on specialized management skills and on their ability to generate cash flow for operating purposes and to make distributions to shareholders or unitholders. REITs may have limited diversification and are subject to risks associated with obtaining financing for real property, as well as to the risk of self-liquidation. REITs also can be adversely affected by their failure to qualify for tax-free pass-through treatment of their income under the Code or their failure to maintain an exemption from registration under the 1940 Act. By investing in REITs indirectly through the Fund, a shareholder bears not only a proportionate share of the expenses of the Fund, but also may indirectly bear similar expenses of some of the REITs in which it invests.

Equity securities in which a Fund may invest include master limited partnerships (“MLPs”). An MLP is an entity, most commonly a limited partnership, that is taxed as a partnership publicly traded and listed on a national securities exchange. Holders of common units of MLPs typically have limited control and limited voting rights as compared to holders of a corporation’s common shares. MLPs are limited by the Code to only apply to enterprises that engage in certain businesses, mostly pertaining to the use of natural resources, such as petroleum and natural gas extraction and transportation, although some other enterprises may also qualify as MLPs.

In order to generate additional income, each Fund may lend portfolio securities representing up to one-third of the value of its total assets to broker-dealers, banks or other institutional borrowers of securities that the Adviser has determined are creditworthy. The securities lending agent will generally bear the risk that a borrower may default on its obligation to return loaned securities; however, a Fund bears the risk that the securities lending agent may default on its contractual obligations to the Fund. A Fund also bears the market risk with respect to the investment of the cash collateral used to secure the loan. A Fund may lose money on its investment of cash collateral or may fail to earn sufficient income on its investment to meet its obligations to the borrower. Each Fund will pay a portion of the income earned on other lending transactions to the placing broker and may pay administrative and custodial fees in connection with these loans.

In these loan arrangements, a Fund will receive cash collateral equal to at least 102% of the value of the securities loaned as determined at the time of loan origination. If the market value of the loaned securities increases, the borrower must furnish additional collateral to the Fund. During the time portfolio securities are on loan, the borrower pays a Fund any dividends or interest paid on the securities. Loans are subject to termination at any time by a Fund or the borrower. While a Fund does not have the right to vote securities on loan, it would terminate the loan and regain the right to vote if that were considered important with respect to the investment.

When a Fund lends portfolio securities to a borrower, payments in lieu of dividends made by the borrower to the Fund will not constitute “qualified dividends” taxable at the same rate as long-term capital gains, even if the actual dividends would have constituted qualified dividends had the Fund held the securities. However, each Fund currently recalls all loaned securities from the borrower so that it may receive dividends paid on the securities, if any.

Each Fund may invest in other investment companies, including open-end funds, closed-end funds, unit investment trusts, and ETFs registered under the 1940 Act (“1940 Act ETFs”). Under the 1940 Act, a Fund’s investment in such securities is generally limited to 3% of the total voting stock of any one investment company; 5% of the Fund’s total assets with respect to any one investment company; and 10% of the Fund’s total assets in the aggregate. 1940 Act ETFs, however, may rely on Rule 12d1-4 under the 1940 Act to invest beyond these statutory limits, subject to certain conditions and pursuant to contractual arrangements between the ETFs and the investing funds. A Fund will only invest in other investment companies and pooled investment vehicles that invest primarily in Fund-eligible investments. A Fund’s investments in other investment companies may include money market mutual funds. Investments in money market funds are not subject to the percentage limitations set forth above.

The Fund may invest in index ETFs, which are index funds bought and sold on a securities exchange. An index ETF trades like common stock and represents a portfolio of securities designed to track a particular market index. ETFs can give exposure to all or a portion of the U.S. market, a foreign market, a region, a commodity, a currency, or to any other index that an ETF tracks. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. An ETF may fail to accurately track the returns of the market segment or index that it is designed to track, and the price of an ETF’s shares may fluctuate. In addition, because they, unlike traditional mutual funds, are traded on an exchange, ETFs are subject to the following risks: (i) the performance of the ETF may not replicate the performance of the underlying index that it is designed to track; (ii) the market price of the ETF’s shares may trade at a premium or discount to the ETF’s NAV; (iii) an active trading market for an ETF may not develop or be maintained; and (iv) there is no assurance that the requirements of the exchange necessary to maintain the listing of the ETF will continue to be met or remain unchanged. Trading in an ETF may be halted if the trading in one or more of the ETF’s underlying securities is halted, which could result in the ETF being more volatile. In the event substantial market or other disruptions affecting ETFs should occur in the future, the liquidity and value of a Fund’s shares could also be substantially and adversely affected.

If a Fund invests in other investment companies or pooled investment vehicles, Fund shareholders will bear not only their proportionate share of the Fund’s expenses, but also, indirectly, the similar expenses of the underlying investment companies or pooled investment vehicles. Shareholders would also be exposed to the risks associated not only to the Fund, but also to the portfolio investments of the underlying investment companies or pooled investment vehicles. Shares of certain closed-end funds may at times be acquired at market prices representing premiums to their NAVs. Shares acquired at a premium to their NAV may be more likely to subsequently decline in price, resulting in a loss to the Fund and its shareholders.

Each Fund may invest in over-the-counter securities. In contrast to the securities exchanges, the over-the-counter market is not a centralized facility that limits trading activity to securities of companies which initially satisfy certain defined standards. Generally, the volume of trading in an unlisted or over-the-counter security is less than the volume of trading in a listed security. This means that the depth of market liquidity of some securities in which each Fund invests may not be as great as that of other securities and, if the Fund were to dispose of such a security, it might have to offer the securities at a discount from recent prices, or sell the securities in small lots over an extended period of time.

Each Fund may from time to time purchase securities on a “when-issued” or other delayed-delivery basis. The price of securities purchased on a when-issued basis is fixed at the time the commitment to purchase is made, but delivery and payment for the securities take place at a later date. Normally, the settlement date occurs within 45 days of the purchase. During the period between the purchase and settlement, no payment is made by a Fund to the issuer and no interest is accrued on debt securities and no dividend income is earned on equity securities. Forward commitments involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. This risk is in addition to the risk of decline in value of a Fund’s other assets. Although when-issued securities may be sold prior to the settlement date, the Fund intends to purchase such securities with the purpose of actually acquiring them. At the time the Fund makes the commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the value of the security in determining its NAV. The Fund does not believe that NAV will be adversely affected by purchases of securities on a when-issued basis.

Each Fund will designate on its books or maintain in a segregated account cash and liquid securities equal in value to commitments for when-issued securities. When the time comes to pay for when-issued securities, a Fund will meet its obligations from then-available cash flow, sale of the segregated securities, sale of other securities or, although it would not normally expect to do so, from the sale of the when-issued securities themselves (which may have a market value greater or less than the Fund’s payment obligation).

A discussion of exchange listing and trading matters associated with an investment in the Funds is contained in the Prospectus under “Purchase and Sale of Shares.” The discussion below supplements, and should be read in conjunction with, such section of the Prospectus.

Each Fund’s shares trade on the Listing Exchange at prices that may differ to some degree from their NAV. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of a Fund’s shares will continue to be met.

The Listing Exchange will consider the suspension of trading in, and will initiate delisting proceedings of, a Fund’s shares under any of the following circumstances: (1) if any of the requirements set forth in the Listing Exchange rules are not continuously maintained; (2) if, where the Listing Exchange has filed a separate proposal under Section 19(b) of the 1940 Act, any of the statements regarding (a) the index composition; (b) the description of a Fund; (c) limitations on a Fund’s portfolio holdings or reference assets; or (d) the applicability of the Listing Exchange listing rules specified in such proposal are not continuously maintained; (3) if, following the initial twelve-month period after the commencement of trading of a Fund on the Listing Exchange, there are fewer than 50 beneficial holders of the shares of such Fund for 30 or more consecutive trading days; (4) if the value of a Fund’s underlying index is no longer calculated or available or an interruption to the dissemination of the value of the index persists past the trading day in which it occurred or the underlying index is replaced with a new index, unless the new underlying index meets certain Listing Exchange requirements; or (5) if such other event shall occur or condition exists that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. In addition, the Listing Exchange will remove the shares from listing and trading upon termination of the Trust or a Fund.

The Trust reserves the right to adjust the share price of a Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

As in the case of other publicly traded securities, brokers’ commissions on transactions in Fund shares will be based on negotiated commission rates at customary levels.

The base and trading currency of each Fund is the U.S. dollar. The base currency is the currency in which a Fund’s NAV per share is calculated and the trading currency is the currency in which shares of a Fund are listed and traded on the Listing Exchange.

The Board oversees the operations and management of the Nuveen Funds, including the duties performed for the Nuveen Funds by the Adviser. The Board has adopted a unitary board structure. A unitary board consists of one group of trustees who serve on the board of every fund in the Nuveen Fund complex. In adopting a unitary board structure, the trustees seek to provide effective governance through establishing a board, the overall composition of which will, as a body, possess the appropriate skills, diversity (including, among other things, gender, race and ethnicity), independence and experience to oversee the Nuveen Funds’ business. With this overall framework in mind, when the Board, through its Nominating and Governance Committee discussed below, seeks nominees for the Board, the trustees consider, not only the candidate’s particular background, skills and experience, among other things, but

also whether such background, skills and experience enhance the Board’s diversity and at the same time complement the Board given its current composition and the mix of skills and experiences of the incumbent trustees. The Nominating and Governance Committee believes that the Board generally benefits from diversity of background (including, among other things, gender, race and ethnicity), skills, experience and views among its members, and considers this a factor in evaluating the composition of the Board, but has not adopted any specific policy on diversity or any particular definition of diversity.

The Board believes the unitary board structure enhances good and effective governance, particularly given the nature of the structure of the investment company complex. Funds in the same complex generally are served by the same service providers and personnel and are governed by the same regulatory scheme which raises common issues that must be addressed by the trustees across the fund complex (such as compliance, valuation, liquidity, brokerage, trade allocation or risk management). The Board believes it is more efficient to have a single board review and oversee common policies and procedures which increases the Board’s knowledge and expertise with respect to the many aspects of fund operations that are complex-wide in nature. The unitary structure also enhances the Board’s influence and oversight over the Adviser and other service providers.

In an effort to enhance the independence of the Board, the Board also has a chair that is an independent trustee. The Board recognizes that a chair can perform an important role in setting the agenda for the Board, establishing the boardroom culture, establishing a point person on behalf of the Board for fund management, and reinforcing the Board’s focus on the long-term interests of shareholders. The Board recognizes that a chair may be able to better perform these functions without any conflicts of interests arising from a position with fund management. Accordingly, the trustees have elected Mr. Toth to serve as the independent Chair of the Board. Specific responsibilities of the Chair include: (i) presiding at all meetings of the Board and of the shareholders; (ii) seeing that all orders and resolutions of the trustees are carried into effect; and (iii) maintaining records of and, whenever necessary, certifying all proceedings of the trustees and the shareholders.

The Audit Committee assists the Board in the oversight and monitoring of the accounting and reporting policies, processes and practices of the Nuveen Funds, and the audits of the financial statements of the Nuveen Funds; the quality and integrity of the financial statements of the Nuveen Funds; the Nuveen Funds’ compliance with legal and regulatory requirements relating to the Nuveen Funds’ financial statements; the independent auditors’ qualifications, performance and independence; and the pricing procedures of the Nuveen Funds and the Adviser’s internal valuation group. It is the responsibility of the Audit Committee to select, evaluate and replace any independent auditors (subject only to Board and, if applicable, shareholder ratification) and to determine their compensation. The Audit Committee is also responsible for, among other things, overseeing the valuation of securities comprising the Nuveen Funds’ portfolios. Subject to the Board’s general supervision of such actions, the Audit Committee addresses any valuation issues, oversees the Nuveen Funds’ pricing procedures and actions taken by the Adviser’s internal valuation group which provides regular reports to the committee, reviews any issues relating to the valuation of the Nuveen Funds’ securities brought to its attention and considers the risks to the Nuveen Funds in assessing the possible resolutions to these matters. The Audit

Committee may also consider any financial risk exposures for the Nuveen Funds in conjunction with performing its functions.

The Nominating and Governance Committee is responsible for seeking, identifying and recommending to the Board qualified candidates for election or appointment to the Board. In addition, the Nominating and Governance Committee oversees matters of corporate governance, including the evaluation of Board performance and processes, the assignment and rotation of committee members, and the establishment of corporate governance guidelines and procedures, to the extent necessary or desirable, and matters related thereto. Although the unitary and committee structure has been developed over the years and the Nominating and Governance Committee believes the structure has provided efficient and effective governance, the committee recognizes that as demands on the Board evolve over time (such as through an increase in the number of funds overseen or an increase in the complexity of the issues raised), the committee must continue to evaluate the Board and committee structures and their processes and modify the foregoing as may be necessary or appropriate to continue to provide effective governance. Accordingly, the Nominating and Governance Committee has a separate meeting each year to, among other things, review the Board and committee structures, their performance and functions, and recommend any modifications thereto or alternative structures or processes that would enhance the Board’s governance of the Nuveen Funds.

The Compliance, Risk Management and Regulatory Oversight Committee (the “Compliance Committee”) is responsible for the oversight of compliance issues, risk management and other regulatory matters affecting the Nuveen Funds that are not otherwise the jurisdiction of the other committees. The Board has adopted and periodically reviews policies and procedures designed to address the Nuveen Funds’ compliance and risk matters. As part of its duties, the Compliance Committee reviews the policies and procedures relating to compliance matters and recommends modifications thereto as necessary or appropriate to the full Board; develops new policies and procedures as new regulatory matters affecting the Nuveen Funds arise from time to time; evaluates or considers any comments or reports from examinations from regulatory authorities and responses thereto; and performs any special reviews, investigations or other oversight responsibilities relating to risk management, compliance and/or regulatory matters as requested by the Board.

In determining that a particular trustee was qualified to serve on the Board, the Board has considered each trustee’s background, skills, experience and other attributes in light of the composition of the Board with no particular factor controlling. The Board believes that trustees need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties, and the Board believes each trustee satisfies this standard. An effective trustee may achieve this ability through his or her educational background; business, professional training or practice; public service or academic positions; experience from service as a board member or executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences. Accordingly, set forth below is a summary of the experiences, qualifications, attributes, and skills that led to the conclusion, as of the date of this document, that each trustee should continue to serve in that capacity. References to the experiences, qualifications, attributes and skills of trustees are pursuant to requirements of the SEC, do not constitute holding out of the Board or any trustee as having any special expertise or experience and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

The Trust does not have a retirement or pension plan. The Trust is a participant in a deferred compensation plan (the “Deferred Compensation Plan”) that permits any independent trustee to elect to defer receipt of all or a portion of his or her compensation as an independent trustee. The deferred compensation of a participating trustee is credited to a book reserve account of the participating Nuveen Funds when the compensation would otherwise have been paid to the trustee. The value of the trustee’s deferral account at any time is equal to the value that the account would have had if contributions to the account had been invested and reinvested in shares of one or more of the eligible Nuveen Funds. An independent trustee may elect to receive distributions in a lump sum or over a period of five years. No participating Nuveen Fund will be liable for any other fund’s obligations to make distributions under the Deferred Compensation Plan.

The Funds have no employees. Each officer of the Trust serves without any compensation from the Funds. The CCO’s compensation, which is composed of base salary and incentive compensation, is paid by the Adviser, with review and input by the Board. Each Fund reimburses the Adviser for an allocable portion of the Adviser’s cost of the CCO’s incentive compensation.

Nuveen Fund Advisors, LLC, each Fund’s investment adviser, has overall responsibility for management of the Funds, oversees the management of each Fund’s portfolio, manages each Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services. In addition, the Adviser arranges for sub-advisory, transfer agency, custody, fund administration and all other non-distribution related services necessary for the Funds to operate. The Adviser is a wholly owned subsidiary of Nuveen, LLC (“Nuveen”), the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie

Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund (“CREF”). The Adviser is located at 333 West Wacker Drive, Chicago, Illinois 60606.

For the management services and facilities furnished by the Adviser under the Management Agreement, each Fund has agreed to pay an annual management fee based on a percentage of the Fund’s average daily net assets, payable monthly, at a rate set forth in the Prospectus under “Fund Management—Management Fees.” From time to time, the Adviser may waive all or a portion of its fee. The Adviser is responsible for substantially all other expenses of the Funds, except any future distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities, fees and expenses of the independent trustees (including any trustees’ counsel fees), certain compensation expenses of the Funds’ chief compliance officer, litigation expenses, and extraordinary expenses. The following table sets forth the management fees paid by each Fund, during the last three fiscal years ended October 31.

The Adviser has selected Teachers Advisors, LLC to serve as sub-adviser to the Funds with primary responsibility for managing each Fund’s portfolio. TAL is a wholly owned subsidiary of Nuveen and an affiliate of the Adviser. TAL also manages the investments of the TIAA-CREF Funds, the TIAA-CREF Life Funds and the TIAA Separate Account VA-1 and serves as sub-adviser to certain other funds managed by Nuveen Fund Advisors. TAL is located at 730 Third Avenue, New York, New York 10017-3206. The Adviser pays TAL a portfolio management fee out of the advisory fee paid to the Adviser for its services to each Fund equal to 50% of the remainder of (a) the management fee payable by the Fund to the Adviser based on average daily net assets pursuant to the Management Agreement, less (b) any management fee waivers, expense reimbursement payments, revenue sharing payments and operating expenses of the Fund borne by the Adviser in respect to the Fund.

As a result of their common ownership by Nuveen and, ultimately, TIAA, Nuveen Fund Advisors and TAL are considered affiliated persons under common control, and the registered investment companies managed by each are considered to be part of the same group of investment companies.

The following individuals have primary responsibility for the day-to-day implementation of the investment strategies of the Funds.

involved in certain investment opportunities that have the effect of restricting or limiting Fund participation in such investment opportunities. Such conflicts and mitigating policies and procedures include the following:

Conflicts may also arise in cases where one or more Funds or Accounts are invested in different parts of an issuer’s capital structure. For example, a Fund (or an Account) could acquire debt obligations of a company while an Account (or a Fund) acquires an equity investment in the same company. In negotiating the terms and conditions of any such investments, the Sub-Adviser (or, in the case of an Account, an affiliated investment adviser) may find that the interests of the debt-holding Fund (or Account) and the equity-holding Account (or Fund) may conflict. If that issuer encounters financial problems, decisions over the terms of the workout could raise conflicts of interest (including, for example, conflicts over proposed waivers and amendments to debt covenants). For example, debt holding Funds (or Accounts) may be better served by a liquidation of an issuer in which they could be paid in full, while equity-holding Accounts (or Funds) might prefer a reorganization of the issuer that would have the potential to retain value for the equity holders. As another example, holders of an issuer’s senior securities may be able to act to direct cash flows away from junior security holders, and both the junior and senior security holders may be a Fund (or an Account). Any of the foregoing conflicts of interest will be discussed and resolved on a case-by-case basis pursuant to policies and procedures designed to mitigate any such conflicts. Any such discussions will factor in the interests of the relevant parties and applicable laws and regulations. The Sub-Adviser may seek to avoid such conflicts, and, as a result, the Sub-Adviser may choose not to make such investments on behalf of the Funds, which may adversely affect the Funds’ performance if similarly attractive opportunities are not available or identified.

Aggregation and Allocation of Orders. The Sub-Adviser and its affiliated investment advisers may aggregate orders of the Funds and Accounts, in each case consistent with the applicable adviser’s policy to seek best execution for all orders. Although aggregating orders is a common means of reducing transaction costs for participating Accounts and Funds, the Sub-Adviser or its affiliated investment advisers may be perceived as causing one Fund or Account to participate in an aggregated transaction in order to increase the Sub-Adviser’s or its affiliated investment advisers’ overall allocation of securities in that transaction or future transactions. Allocations of aggregated trades may also be perceived as creating an incentive for the Sub-Adviser to disproportionately allocate securities expected to increase in value to certain Accounts at the expense of a Fund. In addition, a Fund may bear the risk of potentially higher transaction costs if aggregated trades are only partially filled or if orders are not aggregated at all.

The Sub-Adviser and its affiliated investment advisers have adopted procedures designed to mitigate the foregoing conflicts of interest by treating each Fund and Account they advise fairly and equitably over time in the allocation of investment opportunities and the aggregation and allocation of orders. The procedures also are designed to mitigate conflicts in potentially inconsistent trading and provide guidelines for trading priority. Moreover, the Sub-Adviser’s or its affiliated investment advisers’ trading activities are subject to supervisory review and compliance monitoring to help address and mitigate conflicts of interest and ensure that Funds and Accounts are being treated fairly and equitably over time.

For example, in allocating investment opportunities, a portfolio manager considers an Account’s or Fund’s investment objectives, investment restrictions, cash position, need for liquidity, sector concentration and other objective criteria. In addition, orders for the same single security are generally aggregated with other orders for the same single security received at the same time. If aggregated orders are fully executed, each participating Account or Fund is allocated its pro rata share on an average price and trading cost basis. In the event the order is only partially filled, each participating Account or Fund receives a pro rata share. Portfolio managers are also subject to restrictions on potentially inconsistent trading of single securities, although a portfolio manager may sell a single security short if the security is included in an Account’s or Fund’s benchmark and the portfolio manager is underweight in that security relative to the applicable Account’s or Fund’s benchmark. Moreover, the procedures set forth guidelines under which trading for long sales of single securities over short sales of the same or closely related securities are monitored to ensure that the trades are treated fairly and equitably. Additionally, the Funds’ portfolio managers’ decisions for executing those trades are also monitored.

The Sub-Adviser’s procedures also address basket trades (trades in a wide variety of securities—on average approximately 100 different issuers) used in quantitative strategies. However, basket trades are generally not aggregated or subject to the same types of restrictions on potentially inconsistent trading as single-security trades because basket trades are tailored to a particular index or model portfolio based on the risk profile of a particular Account or Fund pursuing a particular quantitative strategy. In addition, basket trades are not subject to the same monitoring as single-security trades because an automated and systematic process is used to execute trades; however, the Funds’ portfolio managers’ decisions for executing those trades are monitored.

Research. The Sub-Adviser allocates brokerage commissions to brokers who provide execution and research services for the Funds and some or all of the Sub-Adviser’s other clients. Such research services may not always be utilized in connection with the Funds or other client Accounts that may have provided the commission or a portion of the commission paid to the broker providing the services. The Sub-Adviser is authorized to pay, on behalf of the Funds, higher brokerage fees than another broker might have charged in recognition of the value of brokerage or research services provided by the broker. The Sub-Adviser has adopted procedures with respect to these so-called “soft dollar” arrangements, including the use of brokerage commissions to pay for brokers’ in-house and non-proprietary research, the process for allocating brokerage, and the Sub-Adviser’s practices regarding the use of third-party soft dollars.

IPO Allocation. The Sub-Adviser has adopted procedures designed to ensure that it allocates initial public offerings to the Funds and the Sub-Adviser’s other clients in a fair and equitable manner, consistent with its fiduciary obligations to its clients.

Compensation. The compensation paid to the Sub-Adviser for managing the Funds, as well as certain other clients, is based on a percentage of assets under management, whereas the compensation paid to the Sub-Adviser for managing certain other clients is based on cost. However, no client currently pays the Sub-Adviser a performance-based fee. Nevertheless, the Sub-Adviser may be perceived as having an incentive to allocate securities that are expected to increase in value to accounts in which the Sub-Adviser has a proprietary interest or to certain other accounts in which the Sub-Adviser receives a larger asset-based fee.

TIAA. TIAA or its affiliates, including Nuveen, sponsor an array of financial products for retirement and other investment goals, and provide services worldwide to a diverse customer base. Accordingly, from time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual restrictions that arise due to an Account’s investments and/or the internal policies of TIAA or its affiliates designed to comply with such restrictions. As a result, there may be periods, for example, when the Sub-Adviser will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which investment limits have been reached.

by TIAA or its affiliates for the Funds and Accounts that may not be exceeded without the grant of a license or other regulatory or corporate consent. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of the Sub-Adviser, on behalf of the Funds or Accounts, to purchase or dispose of investments or exercise rights or undertake business transactions may be restricted by regulation or otherwise impaired. As a result, the Sub-Adviser, on behalf of the Funds or Accounts, may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when the Sub-Adviser, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

Portfolio managers are compensated through a combination of base salary, annual performance awards, long-term compensation awards and, for certain portfolio managers, equity-like performance based plans. Currently, the annual performance awards and long-term compensation awards are determined using both quantitative (75%) and qualitative factors (25%) including, but not limited to, Investment Ratio, ranking versus Morningstar peers, risk-adjusted variation in return vs. benchmark, and management/peer reviews.

The variable component of a portfolio manager’s compensation is remunerated as: (1) a current year cash bonus; (2) a long-term performance award, which is on a 3-year cliff vesting cycle and (3) an equity-like profits interest plan. Fifty percent (50%) of the long-term award is based on the Fund(s) managed by the portfolio manager during the 3-year vesting period, while the value of the remainder of the long-term award is based on the performance of the TIAA organization as a whole. The equity-like profits interest vests over time and entitles participants to a percentage of Advisors’ annual profits and the profits of its affiliate Nuveen Asset Management. The equity-like profits interest is allocated to individual portfolio managers based on such person’s overall contribution to Advisors and Nuveen Asset Management.

Risk-adjusted investment performance is calculated, where records are available, over one, three and five years, each ending December 31. For each year, the gross excess return (on a before-tax basis) of a portfolio manager’s mandate(s) is calculated versus each mandate’s assigned benchmark. Please see the Funds’ Prospectuses for more information regarding their benchmark indices. An Information Ratio is then calculated utilizing the gross excess return in the numerator and the greater of the 52-week realized Active Risk (tracking error) or a minimum targeted risk level (typically 300 basis points) in the denominator to generate risk-adjusted investment performance.

Performance relative to peers is evaluated using Morningstar percentile rankings for the 1-, 3- and 5-year ratings, when applicable. For managers with less than a 5-year track record, a 0.25 Investment Ratio and a peer ranking at the middle of the Morningstar grouping is used.

Utilizing the quantitative and qualitative factors discussed above, total compensation is calculated and then compared to the compensation data obtained from surveys that include comparable investment firms. It should be noted that the total compensation can be increased or decreased based on the performance of the equity group as a unit and the relative success of the TIAA organization in achieving its financial and operational objectives.

There are generally no differences between the methods used to determine compensation with respect to the Funds and the Other Accounts shown in the table below.

Nuveen Securities, LLC, 333 West Wacker Drive, Chicago, Illinois 60606, serves as the principal underwriter of the Nuveen ETFs, including the Funds, pursuant to a Distribution Agreement dated August 2, 2016 (the “Distribution Agreement”). The Distributor is an affiliate of the Adviser and a subsidiary of Nuveen. The Distributor also serves as the principal underwriter for the Nuveen Mutual Funds, and has served as co-managing underwriter for the shares of the Nuveen Closed-End Funds.

Each Fund has adopted a plan (the “Plan”) pursuant to Rule 12b-1 under the 1940 Act. Rule 12b-1 provides in substance that an open-end management investment company may not engage directly or indirectly in financing any activity which is primarily intended to result in the sale of shares, except pursuant to a plan adopted under the Rule. The Plan authorizes each Fund to pay up to 0.25% in distribution fees to the Distributor. No payments pursuant to the Plan will be made during the next twelve (12) months of operation.

The Plan may be terminated at any time with respect to any class of shares, without the payment of any penalty, by a vote of a majority of the independent trustees who have no direct or indirect financial interest in the Plan or by vote of a majority of the outstanding voting securities of such class. The Plan may be renewed from year to year if approved by a vote of the Board and a vote of the independent trustees who have no direct or indirect financial interest in the Plan cast in person at a meeting called for the purpose of voting on the Plan. The Plan may be continued only if the trustees who vote to approve such continuance conclude, in the exercise of reasonable business judgment and in light of their fiduciary duties under applicable law, that there is a reasonable likelihood that the Plan will benefit a Fund and its shareholders. The Plan may not be amended to increase materially the cost which a class of shares may bear under the Plan without the approval of shareholders, and any other material amendments of the Plan must be approved by the independent trustees by a vote cast in person at a meeting called for the purpose of considering such amendments. During the continuance of the Plan, the selection and

nomination of the independent trustees of the Trust will be committed to the discretion of the independent trustees then in office. With the exception of the Distributor and its affiliates, no “interested person” of a Fund, as that term is defined in the 1940 Act, and no trustee of a Fund has a direct or indirect financial interest in the operation of the Plan or any related agreement.

KPMG LLP, 200 East Randolph Street, Suite 5500, Chicago, Illinois 60601, independent registered public accounting firm, has been selected as auditors for the Funds.

The Funds, the Adviser, the Sub-Adviser, the Distributor and the Board’s independent trustees have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act and, with respect to the Adviser and the Sub-Adviser, Rule 204A-1 under the Investment Advisers Acts of 1940, as amended, addressing personal securities transactions and other conduct by investment personnel and other persons who may have access to information about the Funds’ securities transactions. The codes are intended to address potential conflicts of interest that can arise in connection with personal trading activities of such persons. Persons subject to the codes are generally permitted to engage in personal securities transactions, including investing in securities eligible for investment by the Funds, subject to certain prohibitions, which may include prohibitions on investing in certain types of securities, pre-clearance requirements, blackout periods, annual and quarterly reporting of personal securities holdings and limitations on personal trading of initial public offerings. Violations of the codes are subject to review by the Board and could result in severe penalties.

The Funds have delegated authority to the Adviser to vote proxies for securities held by the Funds, and the Adviser has in turn delegated that responsibility to the Sub-Adviser. The Adviser’s proxy voting policy establishes minimum standards for the exercise of proxy voting authority by the Sub-Adviser.

The Sub-Adviser has implemented policies, procedures and processes designed to prevent conflicts of interest from influencing proxy voting decisions. These include (i) a clear separation of proxy voting functions from external client relationship and sales functions; and (ii) the active monitoring by the Sub-Adviser’s legal and compliance professionals of required annual disclosures of potential conflicts of interest by individuals who have direct roles in executing or influencing the Funds’ proxy voting (e.g., the Sub-Adviser’s proxy voting professionals, or a senior executive of the Sub-Adviser or the Sub-Adviser’s affiliates).

There could be rare instances in which an individual who has a direct role in executing or influencing the Funds’ proxy voting (e.g., the Sub-Adviser’s proxy voting professionals or a senior executive of the Sub-Adviser or the Sub-Adviser’s affiliates) is either a director or executive of a portfolio company or may have some other association with a portfolio company. In such cases, this individual is required to recuse himself or herself from all decisions related to proxy voting for that portfolio company.

Voted Proxies. Information regarding how the Funds voted proxies relating to portfolio securities during the most recent period ended June 30 will be available without charge by calling (800) 257-8787 or by accessing the SEC’s website at http://www.sec.gov.

The Sub-Adviser is responsible for decisions to buy and sell securities for the Funds as well as for selecting brokers and, where applicable, negotiating the amount of the commission rate paid. It is the intention of the Sub-Adviser to place brokerage orders with the objective of obtaining the best execution. In evaluating best execution for transactions, the Sub-Adviser considers a number of factors, including, without limitation, the following: best price; the nature of the security being traded; the nature and character of the markets for the security to be purchased or sold; the likely market impact of the transaction based on the nature of the transaction; the skill of the executing broker; the liquidity being provided by the broker; the broker-dealer’s settlement and clearance capability; the reputation and financial condition of the broker-dealer; the costs of processing information; the nature of price discovery in different markets; and the laws and regulations governing investment advisers. When purchasing or selling securities traded on the over-the-counter market, the Sub-Adviser generally will execute the transactions with a broker engaged in making a market for such securities. When the Sub-Adviser deems the purchase or sale of a security to be in the best interests of one or more Funds, its personnel may, consistent with its fiduciary obligations, decide either to buy or to sell a particular security for the Fund(s) at the same time as for other funds that it may be managing, or that may be managed by its affiliated investment advisers. In that event, allocation of the securities purchased or sold, as well as the expenses incurred in the transaction, will be made in an equitable manner.

Transactions on equity exchanges, commodities markets and other agency transactions involve the payment of negotiated brokerage commissions. Such commissions vary among different brokers. Transactions in foreign investments also have negotiated commission rates and they are for the most part the same for all brokers in a particular country with a few exceptions. Trades are regularly monitored for best execution purposes by the equity trading desk.

The Sub-Adviser’s fixed-income traders select the broker-dealers (sell-side) with whom they do business independent of any research, strategy pieces or trade recommendations provided to the Sub-

Adviser. The vast majority of institutional fixed-income trading is conducted over-the-counter rather than on exchanges, with set prices plus commissions. Fixed-income trading is based on the risk-taking practice of market making by sell-side firms, which attempt to capture the bid/ask spread on trades where capital is committed (principal model) or on a pre-negotiated spread concession for riskless principal trades (agency model).

The fixed-income marketplace does not use a voting system to rate broker-dealers with the intent of using those rankings to direct or allocate trades. The directive to the Sub-Adviser’s fixed-income traders, and the conventional trading construct within the fixed-income market, is based on the practice of fiduciary efforts to achieve best execution. The research, credit opinions and relative value trade recommendations provided by the Sub-Adviser’s sell-side counterparts are evaluated, but there is no direct linkage between that evaluation and the Sub-Adviser’s selection of a particular broker-dealer for trade execution. When selecting a broker, the traders follow established trading protocols for data aggregation, price discovery, inventory mining and information protection and conduct an assessment of counterparty performance. The protocol incorporates the Sub-Adviser’s knowledge of and experience with select broker-dealers with respect to providing liquidity, namely the highest bid price or lowest offer price for a particular security.

Every broker is formally approved by the Equity or Fixed-Income Best Execution Committee, as appropriate, which is comprised of representatives from trading, portfolio management, compliance and law. Risk management also reviews the creditworthiness of all brokers.

Fixed-income trades on behalf of the Funds may not be allocated in order to generate soft dollar credits, but at times, a broker may send the Sub-Adviser unsolicited proprietary research that may be based, in part, on fixed-income trading volume directed to that broker. Similarly, trades on behalf of the Funds that follow an index or quantitative strategy, or execution-only trades, may not generate soft dollars, but, at times, a broker may send the Sub-Adviser unsolicited proprietary research that is based, in part, on such trades.

In accordance with the 1940 Act, the Funds have adopted a policy prohibiting the Funds from compensating brokers or dealers for the sale or promotion of a Fund’s shares by the direction of portfolio securities transactions for the Fund to such brokers or dealers. In addition, the Sub-Adviser has instituted policies and procedures so that the Sub-Adviser’s personnel do not violate this policy of the Funds.

The following table sets forth the aggregate brokerage commissions paid by the Funds during the specified periods.

From time to time, the Sub-Adviser may effect purchases and sales of securities between the Funds and other funds or clients advised by the Sub-Adviser or an affiliate (such transactions referred to herein as “cross trades”) if it believes that such transactions are beneficial for each party and consistent with each party’s investment objectives and guidelines, subject to applicable law and regulation. Cross trades may give rise to potential conflicts of interest for the Sub-Adviser. On any occasion when a Fund participates in a cross trade, the Sub-Adviser and the Fund will comply with procedures adopted pursuant to Rule 17a-7 under the 1940 Act and applicable SEC guidance.

The Trust has adopted policies that govern the dissemination of the Funds’ portfolio holdings. The Funds and their service providers may not receive compensation or any other consideration (which includes any agreement to maintain assets in the Funds or in other investment companies or accounts managed by the Adviser or any affiliated person of the Adviser) in connection with the disclosure of portfolio holdings information of the Funds. The policies adopted by the Trust are implemented and overseen by the Chief Compliance Officer of the Funds, subject to the oversight of the Board. Compliance officers of the Funds, the Adviser and Sub-Adviser periodically monitor overall compliance with the policies to ascertain whether portfolio holdings information is disclosed in a manner that is consistent with the policies. Periodic reports regarding these policies will be provided to the Board. The Board must approve all material amendments to these policies. Prior to the commencement of trading on each day that a Fund is open for business, (1) the Funds’ portfolio holdings are publicly disseminated on the Funds’ publicly accessible website, www.nuveen.com/etf, and through financial reporting and news services, and (2) the composition of the basket of securities and/or cash that will constitute a Creation Unit is publicly disseminated via the National Securities Clearing Corporation, a clearing agency registered with the SEC (“NSCC”).

The Trust, the Adviser and/or Sub-Adviser, and the Distributor will generally not disseminate non-public portfolio holdings information concerning the Funds. However, non-public portfolio holdings information may be provided to certain parties if approved by the Funds’ Chief Administrative Officer or Secretary upon a determination that there is a legitimate business purpose for doing so, the disclosure is consistent with the interests of the Funds, and the recipient is obligated to maintain the confidentiality of the information and not misuse it.

There is no assurance that the Trust’s policies on portfolio holdings disclosure will protect the Funds from the potential misuse of portfolio holdings information by individuals or firms in possession of such information.

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “Purchase and Sale of Shares.”

The Depository Trust Company (“DTC”) acts as securities depositary for the shares. Shares of the Funds are represented by securities registered in the name of DTC or its nominee, Cede & Co., and deposited with, or on behalf of, DTC. Except in the limited circumstance provided below, certificates will not be issued for shares.

DTC, a limited-purpose trust company, was created to hold securities of its participants (the “DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the New York Stock Exchange (“NYSE”) and FINRA. Access to the DTC system is also available to other banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (the “Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of the Funds held by each DTC Participant. The Trust, either directly or through a third party service, shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust, either directly or through a third party service, shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant and/or third party service a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of the Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants.

DTC may determine to discontinue providing its service with respect to shares at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action either to find a replacement for DTC to perform its functions or, if such a replacement is unavailable, to issue and deliver printed certificates representing ownership of shares, unless the Trust makes other arrangements with respect thereto satisfactory to the Listing Exchange.

An Authorized Participant may hold of record more than 25% of the outstanding shares of a Fund. From time to time, Authorized Participants may be a beneficial and/or legal owner of a Fund, may be affiliated with an index provider, may be deemed to have control of a Fund and/or may be able to affect the outcome of matters presented for a vote of the shareholders of a Fund. Authorized Participants may execute an irrevocable proxy granting the Distributor or an affiliate of the Distributor (the “Agent”) power to vote or abstain from voting such Authorized Participant’s beneficially or legally owned shares of a Fund. When granted the power to vote, the Agent shall mirror vote such shares in the same proportion as all other beneficial owners of a Fund.

It is also possible that, from time to time, Nuveen or its affiliates may, subject to compliance with applicable law, purchase and hold shares of a Fund. Nuveen and its affiliates reserve the right, subject to compliance with applicable law, to sell at any time some or all of the shares of a Fund acquired for their own accounts. A large sale of shares of a Fund by Nuveen or its affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s market price.

Only Authorized Participants may purchase and redeem Creation Units directly from the Funds at NAV. To become an Authorized Participant, a firm must execute an Authorized Participant Agreement (the “Participant Agreement”) that has been agreed to by the Distributor and BBH, in a form approved by the Trust. Among other things, the Participant Agreement requires that an Authorized Participant be (i) a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC or (ii) a DTC Participant.

The Funds issue and redeem Creation Units through the Distributor at their NAV next determined after receipt of an order in proper form on any Business Day. All orders to purchase or redeem Creation Units directly from the Funds, including non-standard orders (as defined below), must be placed in the manner and by the time specified by a Fund on each Business Day (generally, 4 p.m., Eastern time) (the “Cut-Off Time”). The date on which an order to purchase or redeem Creation Units is received in proper form and is accepted by the Distributor is referred to as the “Order Placement Date.” An order is generally considered to be in “proper form” if all procedures set forth in the Participant Agreement, the AP Handbook and this SAI are properly followed.

An Authorized Participant submitting a creation or redemption order is deemed to make certain representations to the Trust as set forth in the Participant Agreement. The Distributor reserves the right to verify these representations in its discretion. If the Authorized Participant, upon receipt of a verification request, does not provide sufficient verification of its representations as determined by the Distributor in its sole discretion, the order will not be considered to have been received in proper form and may be rejected by the Distributor.

Fund Deposit. The consideration for purchase of a Creation Unit of a Fund generally consists of (a) either (i) the in-kind deposit of a designated portfolio of securities (the “Deposit Securities”) per each Creation Unit or (ii) the cash value of the Deposit Securities (“Deposit Cash”) and (b) the Cash Component, defined and computed as described below. Together, the Deposit Securities or Deposit Cash, as applicable, and the Cash Component constitute the “Fund Deposit,” the value of which equals the NAV of a Creation Unit of a Fund on any given Order Placement Date. In addition to the Fund Deposit, Authorized Participants will be charged a standard fixed transaction fee and, for purchases effected in whole or in part with Deposit Cash, a variable transaction fee intended to cover the costs a Fund incurs in acquiring portfolio securities with such Deposit Cash. See “Transaction Fees” below for additional information.

The “Cash Component” is an amount equal to the difference between the NAV of the shares (per Creation Unit) and the market value of the Deposit Securities or Deposit Cash, as applicable. The Cash Component serves the function of compensating for any differences between the NAV per Creation Unit and the market value of the Deposit Securities or Deposit Cash, as applicable. The Cash Component may include a “Dividend Equivalent Payments,” which enables a Fund to make a complete distribution of dividends on the day preceding the next dividend payment date, and is an amount equal, on a per Creation Unit basis, to the dividends on all the portfolio securities of a Fund (“Dividend Securities”) with ex-dividend dates within the accumulation period for such distribution (the “Accumulation Period”), net of expenses and liabilities for such period, as if all of the Dividend Securities had been held by a Fund for the entire Accumulation Period. The Accumulation Period begins on the ex-dividend date for the Funds and ends on the day preceding the next ex-dividend date. If the Cash Component is a positive number (i.e., the NAV per Creation Unit exceeds the market value of the Deposit Securities or Deposit Cash, as applicable), the Cash Component shall be such positive amount. If the Cash Component is a negative number (i.e., the NAV per Creation Unit is less than the market value of the Deposit Securities or Deposit Cash, as applicable), the Cash Component shall be such negative amount and the Authorized Participant will be entitled to receive cash in an amount equal to the Cash Component. Computation of the Cash Component excludes any stamp duty or other similar fees and expenses payable upon transfer of

beneficial ownership of the Deposit Securities, if applicable, which shall be the sole responsibility of the Authorized Participant.

BBH, through NSCC, makes available on each Business Day, prior to the opening of business on the NYSE (currently 9:30 a.m., Eastern time) (the “NYSE Open”), the list of the names and the required number of shares of each Deposit Security or the required amount of Deposit Cash, as applicable, to be included in the Fund Deposit (based on information at the end of the previous Business Day) for each Fund on such day. Such Fund Deposit is subject to any applicable adjustments, as described below, in order to effect purchases of Creation Units of a Fund until such time as the next-announced composition of the Deposit Securities or the required amount of Deposit Cash, as applicable, is made available.

The identity and number of shares of the Deposit Securities or the amount of Deposit Cash, as applicable, required for a Fund Deposit for each Fund may be changed from time to time by the Adviser with a view to achieving the investment objective of a Fund. Information regarding the Fund Deposit necessary for the purchase of a Creation Unit is made available to Authorized Participants and other market participants seeking to transact in Creation Unit aggregations. The composition of the Deposit Securities may also change in response to rebalancing adjustments, interest payments, corporate action events and adjustments to the weighting or composition of the component securities of a Fund’s underlying Index.

The Trust reserves the right to permit or require the substitution of Deposit Cash to replace any or all Deposit Securities, including, without limitation, in situations where a Deposit Security: (i) may not be available in sufficient quantity for delivery; (ii) may not be eligible for transfer through the systems of DTC for corporate securities and municipal securities or the Federal Reserve System for U.S. Treasury securities; (iii) may not be eligible for trading by an Authorized Participant or the investor for which it is acting; (iv) would be restricted under the securities laws; or (v) in certain other situations (collectively, “non-standard orders”). The Trust also reserves the right to: (i) permit or require the substitution of Deposit Securities in lieu of Deposit Cash and (ii) include or remove Deposit Securities from the Fund Deposit in anticipation of Index rebalancing changes.

Procedures for Purchase of Creation Units. Fund Deposits must be delivered by an Authorized Participant through the Federal Reserve System (for cash and U.S. government securities), through DTC (for corporate securities and municipal securities), through a subcustody agent (for foreign securities) and/or through such other arrangements allowed by the Trust or its agents. Foreign Deposit Securities must be delivered to an account maintained on behalf of a Fund at its applicable local subcustodian. Transfer of the Fund Deposit and all applicable transaction fees must be ordered by the Authorized Participant in a timely fashion so as to ensure delivery to the account of a Fund or its agents by no later than 3:00 p.m. Eastern time on the date on which the Creation Units are to be delivered (the “Settlement Date”), which for purchases is generally the second Business Day after the Order Placement Date. All questions as to the number of Deposit Securities or Deposit Cash to be delivered, as applicable, and the validity, form and eligibility (including time of receipt) for the deposit of any securities or cash, as applicable, will be determined by the Distributor, whose determination shall be final and binding. If the Deposit Securities or Deposit Cash, as applicable, are not received in a timely manner by the Settlement Date, the purchase order may be cancelled and the Authorized Participant shall be liable to a Fund for losses, if any, resulting therefrom. Any such cancelled order may be resubmitted the following Business Day using the Fund Deposit required for such Business Day.

Investors placing orders through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order by the Cut-Off Time on such Business Day. An Authorized Participant may require an investor to make certain representations or enter into agreements with respect to the order (e.g., to provide for payments of cash, when required). Investors should be aware that their particular broker may not be an Authorized Participant, in which case orders to purchase shares directly from a Fund in Creation Units would have to be placed by the investor’s broker through an Authorized Participant. In such cases, the Authorized Participant may impose additional charges on such investor. At any given time, there may be only a limited number of Authorized Participants, and only a small number of such Authorized Participants may have international capabilities.

the sum of (i) the Cash Component, (ii) all applicable transaction fees and (iii) an additional amount of cash equal to a percentage of the market value, as set forth in the Participant Agreement, of the undelivered Deposit Securities (the “Cash Collateral”), which shall be maintained by BBH in a general non-interest bearing collateral account. An additional amount of cash shall be required to be deposited with a Fund, pending delivery of the missing Deposit Securities, to the extent necessary to maintain the Cash Collateral with a Fund in an amount at least equal to the applicable percentage, as set forth in the Participant Agreement, of the daily marked to market value of the missing Deposit Securities. A Fund may use such Cash Collateral to buy the missing Deposit Securities at any time. Authorized Participants will be liable to a Fund for all costs, expenses, dividends, income and taxes associated with missing Deposit Securities, including the costs incurred by a Fund in connection with any such purchases. These costs will be deemed to include the amount by which the actual purchase price of the Deposit Securities exceeds the market value of such Deposit Securities on the Order Placement Date plus the brokerage and related transaction costs associated with such purchases. A Fund will return any unused portion of the Cash Collateral once all of the missing Deposit Securities have been properly received by BBH. The delivery of Creation Units so created generally will occur no later than the Settlement Date.

The Distributor reserves the right to reject a purchase order in its discretion, including, without limitation, if (a) the order is not in proper form; (b) the Deposit Securities or Deposit Cash, as applicable, delivered by the Authorized Participant do not match those disseminated through the facilities of NSCC for that date; (c) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of a Fund; (d) the acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (e) the acceptance or receipt of the order for a Creation Unit would, in the opinion of counsel to the Funds, be unlawful; or (f) in the event that circumstances outside the control of the Funds, the Distributor, BBH and/or the Adviser make it for all practical purposes not feasible to process orders for Creation Units (examples of such circumstances include acts of God or public service or utility problems such as fires, floods, extreme weather conditions and power outages resulting in telephone, telecopy and computer failures; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the Funds, the Distributor, BBH, DTC, NSCC, Federal Reserve System, or any other participant in the creation process; and other extraordinary events). The Funds or its agents shall communicate to the Authorized Participant the rejection of an order. The Funds, the Distributor and BBH are under no duty, however, to give notification of any defects or irregularities in any order or in the delivery of Fund Deposits, nor shall any of them incur any liability for the failure to give any such notification. The Funds, the Distributor and BBH shall not be liable for the rejection of any purchase order for Creation Units.

Shares may be redeemed only in Creation Units at their NAV next determined after receipt of a redemption request in proper form on a Business Day. EXCEPT UPON LIQUIDATION OF A FUND, THE FUND WILL NOT REDEEM SHARES IN AMOUNTS LESS THAN CREATION UNITS. Investors must accumulate enough Fund shares in the secondary market to constitute a Creation Unit in order to have such shares redeemed by a Fund. There can be no assurance, however, that there will be sufficient liquidity in the public trading market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of Fund shares to constitute a redeemable Creation Unit.

Redemption proceeds for a Creation Unit will be paid either in-kind or in cash, or a combination thereof, as disclosed by BBH prior to the NYSE Open. With respect to in-kind redemptions, BBH, through NSCC, makes available prior to the NYSE Open on each Business Day the list of the names and share quantities of each Fund’s portfolio securities (subject to possible amendment or correction) that will be distributed upon the receipt of redemption requests in proper form prior to the Cut-Off Time on that day (“Fund Securities”).

In connection with any in-kind redemptions, Authorized Participants will also pay or receive cash in an amount equal to the difference between the NAV of the Creation Units being redeemed and the value of the Fund Securities received (the “Cash Redemption Component”). In the event that the Fund Securities have a value greater than the NAV of the Creation Units, a Cash Redemption Component equal to the differential is required to be paid to the Funds by the Authorized Participant. In the event that the Fund Securities have a value less than the NAV of the Creation Units, a Cash Redemption Component equal to the differential will be paid by the Funds to the Authorized Participant. Notwithstanding the foregoing, at a Fund’s discretion, an Authorized Participant may receive the corresponding cash value of all or a portion of the Fund Securities.

Procedures for Redemption of Creation Units. After an order for redemption in proper form has been received, the Funds will initiate procedures to transfer the requisite Fund Securities and the Cash Redemption Component to the Authorized Participant by the Settlement Date. With respect to in-kind redemptions of the Funds, the calculation of the value of the Fund Securities and the Cash Redemption Component to be delivered upon redemption will be made by BBH according to the procedures set forth under “Determination of Net Asset Value,” computed on the Order Placement Date. Therefore, if a redemption order in proper form is submitted by an Authorized Participant by the Cut-Off Time on the Order Placement Date, and the requisite number of shares of the Funds are delivered to BBH prior to 3:00 p.m. Eastern time on the Settlement Date, then the value of the Fund Securities and the Cash Redemption Component to be delivered will be determined on such Order Placement Date. If the requisite number of shares of the Funds are not delivered by 3:00 p.m. Eastern time on the Settlement Date, the Funds will not release the Fund Securities for delivery unless collateral is posted in such percentage amount of missing shares as set forth in the Participant Agreement (marked to market daily).

If it is not possible to effect deliveries of the Fund Securities, a Fund may, in its sole discretion, exercise its option to redeem shares in cash, and the redeeming Authorized Participant will be required to receive its redemption proceeds in cash. In addition, an Authorized Participant may request a redemption in cash that the Fund may, in its sole discretion, permit. In either case, the Authorized Participant will receive a cash payment equal to the NAV of its shares on the Order Placement Date, minus a fixed transaction fee and an additional variable transaction fee, each as described in further detail below under “Transaction Fees,” to offset the Trust’s brokerage and other transaction costs associated with the disposition of portfolio securities necessary to fund the redemption in cash.

Redemptions of shares for Fund Securities will be subject to compliance with applicable federal and state securities laws, and the Funds (whether or not it otherwise permits cash redemptions) reserve the right to redeem Creation Units for cash to the extent that it could not lawfully deliver specific Fund Securities or could not do so without first registering the Fund Securities under such laws. An Authorized Participant (or a client for which it is acting) subject to a legal restriction with respect to a particular security included in the Fund Securities may be paid an equivalent amount of cash. The Authorized Participant may request a redeeming client to complete certain documentation with respect to such matters. Further, an Authorized Participant that is not a “qualified institutional buyer” (“QIB”), as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A. An Authorized Participant may be required by a Fund to provide a written confirmation with respect to QIB status in order to receive Fund Securities. Redemptions effected in cash will be subject to applicable transaction fees.

The right of redemption may be suspended or the Settlement Date postponed with respect to a Fund (1) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings); (2) for any period during which trading on the Listing Exchange is suspended or restricted; (3) for any period during which an emergency exists as a result of which redemption of shares of a Fund or determination of the NAV of the shares is not reasonably practicable; or (4) in such other circumstance as is permitted by the SEC.

Notwithstanding the foregoing, a Fund may require orders to be placed earlier than the normal Cut-Off Time, and in certain circumstances up to 23 hours prior to the normal Cut-Off Time. Authorized Participants will be notified in the event that the Cut-Off Time for an order will be earlier than normal on any particular Business Day. Orders to purchase shares that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) that the markets in the relevant foreign market are closed may not be accepted.

applicable, on a given day that does not vary with the number of Creation Units created or redeemed on that day. Additional variable transaction fees will be applied to certain creation and redemption transactions, including non-standard orders and whole or partial cash purchases or redemptions. The following table shows, as of the date of this SAI, the approximate value of one Creation Unit and the standard fixed and maximum additional variable transaction fees for creations and redemptions (as described above):

* As a percentage of the NAV per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

The Funds may adjust the transaction fees from time to time upon notice to Authorized Participants. The Adviser may also from time to time cover the cost of any transaction fees if it determines it is in a Fund’s best interest.

In addition, with respect to creation orders, Authorized Participants are responsible for the costs of transferring the securities constituting the Deposit Securities to the Fund and with respect to redemption orders, Authorized Participants are responsible for the costs of transferring the Fund Securities from the Funds to their account or as otherwise specified on their order. Investors who use the services of a broker or other such intermediary may also be charged a fee by such intermediary for such services.

Each Fund issues shares of beneficial interest, par value $.01 per share. The Board has the right to establish additional series in the future, to determine the preferences, voting powers, rights and privileges thereof and to modify such preferences, voting powers, rights and privileges without shareholder approval.

The Trust is not required to and does not intend to hold annual meetings of shareholders. The Trust’s Declaration of Trust (the “Declaration”) requires a shareholder vote only on those matters where the 1940 Act requires a vote of shareholders and otherwise permits the Trustees to take actions without seeking the consent of shareholders. For example, the Declaration gives the Trustees the authority to approve reorganizations between a Fund and another entity, such as another ETF, or the sale of all or substantially all of a Fund’s assets, or the termination of the Trust or a Fund without shareholder approval if the 1940 Act would not require such approval. Each share has one vote with respect to matters upon which a shareholder vote is required, consistent with the requirements of the 1940 Act and the rules promulgated thereunder. Shares of all series of the Trust vote together as a single class except as otherwise required by the 1940 Act, or if the matter being voted on affects only a particular series; and, if a matter affects a particular series differently from other series, the shares of that series will vote separately on such matter.

The Trustees establish the number of Trustees and may fill vacancies on the Board, except when election of Trustees by the shareholders is required under the 1940 Act. Trustees are then elected by a

plurality of votes cast by shareholders at a meeting at which a quorum is present. The Declaration also provides that Trustees may be removed, with cause, by a vote of shareholders holding at least two-thirds of the voting power of the Trust, or by a vote of two-thirds of the remaining Trustees. “Cause” requires willful misconduct, dishonesty, fraud or a felony conviction. The provisions of the Declaration relating to the election and removal of Trustees may not be amended without the approval of two-thirds of the Trustees.

Under the Declaration, by becoming a shareholder of a Fund, each shareholder is expressly held to have agreed to be bound by the provisions of the Declaration and the Trust’s By-laws. The Declaration may, except in limited circumstances, be amended by the Trustees in any respect without a shareholder vote. Shareholders may be required to disclose information on direct or indirect ownership of a Fund’s shares in order to comply with various laws applicable to a Fund or as the Trustees may determine, and ownership of a Fund’s shares may be disclosed by a Fund if so required by law or regulation. In addition, pursuant to the Declaration, the Trustees may, in their discretion, require the Trust to redeem shares held by any shareholder for any reason under terms set by the Trustees.

In order to permit legitimate inquiries and claims while avoiding the time, expense, distraction and other harm that can be caused to the Funds or their shareholders as a result of spurious shareholder claims, demands and derivative actions, the Declaration provides a detailed process for the bringing of derivative actions by shareholders, and provides that actions that are derivative in nature may not be brought directly. Consistent with applicable Massachusetts law, prior to bringing a derivative action, a demand must first be made on the Trustees. The Declaration details various information, certifications, undertakings and acknowledgements that must be included in the demand. If a majority of the Trustees who are considered independent for the purposes of considering the demand determine that maintaining the suit would not be in the best interests of the Funds, the Trustees are required to reject the demand and the complaining shareholder may not proceed with the derivative action unless the shareholder is able to sustain the burden of proof to a court that the decision of the Trustees not to pursue the requested action was not a good faith exercise of their business judgment on behalf of the Funds. In making such a determination, a Trustee is not considered to have a personal financial interest by virtue of being compensated for his or her services as a Trustee. If a demand is rejected, the complaining shareholder may be responsible for a Fund’s costs and expenses if a court determines that a derivative action was made without reasonable cause or for an improper purpose, if a derivative or direct action is dismissed on the basis of a failure to comply with the procedural provisions relating to shareholder actions as set forth in the Declaration or if a direct action is dismissed by a court for failure to state a claim. Any shareholder bringing an action against a Fund waives the right to trial by jury to the fullest extent permitted by law and any action commenced by a shareholder may be brought only in the U.S. District Court for the District of Massachusetts (Boston Division) or if any such action may not be brought in that court, then in the Business Litigation Session of Suffolk Superior Court in Massachusetts (the “Chosen Courts”), under the terms of the Declaration. Except as prohibited by law, if a shareholder commences an applicable action in a court other than a Chosen Court, the shareholder may be obligated to reimburse a Fund and any applicable Trustee or officer of a Fund made party to such proceeding for the costs and expenses (including attorneys’ fees) incurred in connection with any successful motion to dismiss, stay or transfer of the action.

The Declaration specifically provides, however, that no provision of the Declaration is effective to require a waiver of compliance with any provision of, or restrict any shareholder rights expressly granted by, the 1933 Act, the Securities Exchange act of 1934, as amended, or the 1940 Act, or any rule, regulation or order of the Securities and Exchange Commission thereunder. The provisions of the Declaration are severable, and if the Trustees determine, with the advice of counsel, that any such provision, in whole or in part, conflict with applicable laws and regulations, the conflicting provisions, or part or parts thereof, will be deemed to be not part of the Declaration (provided, that any such determination will not render any of the remaining provisions invalid or improper).

Under Massachusetts law applicable to Massachusetts business trusts, shareholders of such a trust may, under certain circumstances, be held personally liable as partners for its obligations. However, the Declaration contains an express disclaimer of shareholder liability for acts or obligations of the Trust and requires that notice of this disclaimer be given in each agreement, obligation or instrument entered into or executed by the Trust or the Trustees. The Declaration further provides for indemnification out of the assets and property of the Trust for all losses and expenses of any shareholder held personally liable for the obligations of the Trust. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which both inadequate insurance existed and the Trust

or a Fund itself was unable to meet its obligations. The Trust believes the likelihood of the occurrence of these circumstances is remote.

The Declaration further provides that a Trustee acting in his or her capacity as Trustee is not personally liable to any person other than the Trust or its series, in connection with the affairs of the Trust or for any act, omission, or obligation of the Trust. A Trustee is liable only for his or her own bad faith, willful misfeasance, gross negligence or reckless disregard of his or her duties involved in the conduct of his or her office. The Declaration requires the Trust to indemnify any persons who are or who have been Trustees, officers or employees of the Trust for any liability for actions or failure to act except to the extent prohibited by applicable federal law. In making any determination as to whether any person is entitled to the advancement of expenses in connection with a claim for which indemnification is sought, such person is entitled to a rebuttable presumption that he or she did not engage in conduct for which indemnification is not available. The Declaration provides that any Trustee who serves as chair of the Board or of a committee of the Board, lead independent Trustee, or audit committee financial expert, or in any other similar capacity will not be subject to any greater standard of care or liability because of such position.

Shareholder inquiries may be made by writing to the Trust, c/o the Distributor, Nuveen Securities, LLC, at 333 West Wacker Drive, Chicago, Illinois 60606.

The following discussion of certain U.S. federal income tax consequences of investing in the Funds is based on the Code, U.S. Treasury regulations, and other applicable authority, all as in effect as of the date of the filing of this SAI. These authorities are subject to change by legislative or administrative action, possibly with retroactive effect. The following discussion is only a summary of some of the important U.S. federal income tax considerations generally applicable to investments in the Funds. Unless you are a tax-exempt entity or your investment in the Funds is made through a tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when the Funds make distributions or you sell Fund shares. There may be other tax considerations applicable to particular shareholders. Shareholders should consult their own tax advisors regarding their particular situation and the possible application of foreign, state, and local tax laws.

Each Fund has elected or intends to elect to be treated, and intends to qualify each year, as a RIC under Subchapter M of the Code. In order to qualify for the special tax treatment accorded RICs and their shareholders, each Fund must, among other things:

(a) derive at least 90% of its gross income each year from (i) dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock or securities or foreign currencies, or other income (including but not limited to gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and (ii) net income derived from interests in “qualified publicly traded partnerships” (as defined below);

(b) diversify its holdings so that, at the end of each quarter of its taxable year, (i) at least 50% of the market value of a Fund’s total assets consists of cash and cash items, U.S. government securities, securities of other RICs and other securities, with investments in such other securities limited with respect to any one issuer to an amount not greater than 5% of the value of a Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of a Fund’s total assets is invested, including through corporations in which a Fund owns a 20% or more voting stock interest, in (1) the securities (other than those of the U.S. government or other RICs) of any one issuer or two or more issuers that are controlled by a Fund and that are engaged in the same, similar or related trades or businesses or (2) the securities of one or more qualified publicly traded partnerships; and

(c) distribute with respect to each taxable year an amount equal to or greater than the sum of 90% of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid—generally taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and 90% of its net tax-exempt interest income.

In general, for purposes of the 90% qualifying income test described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership that would be qualifying income if realized directly by a Fund. However, 100% of the net income derived from an interest in a “qualified publicly traded partnership” (generally, a partnership (i) interests in which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof, and (ii) that derives less than 90% of its income from the qualifying income described in clause (a)(i) of the description of the 90% qualifying income test applicable to RICs, above) will be treated as qualifying income.

If a Fund qualifies for treatment as a RIC, the Fund will generally not be subject to federal income tax on income and gains that are distributed in a timely manner to its shareholders in the form of dividends. The Board reserves the right not to maintain the qualification of a Fund as a RIC if it determines such course of action to be beneficial to shareholders.

If, for any taxable year, a Fund was to fail to qualify as a RIC or was to fail to meet the distribution requirement described above, it would be taxed in the same manner as an ordinary corporation and distributions to its shareholders would not be deductible by a Fund in computing its taxable income. In addition, a Fund’s distributions, to the extent derived from the Fund’s current and accumulated earnings and profits, including any distributions of net long-term capital gains, would be taxable to shareholders as ordinary dividend income for federal income tax purposes. However, such dividends would be eligible, subject to any generally applicable limitations, (i) to be treated as qualified dividend income in the case of shareholders taxed as individuals and (ii) for the dividends-received deduction in the case of corporate shareholders. Moreover, a Fund would be required to pay out its earnings and profits accumulated in that year in order to qualify for treatment as a RIC in a subsequent year. Under certain circumstances, a Fund may be able to cure a failure to qualify as a RIC, but in order to do so the Fund may incur significant Fund-level taxes and may be forced to dispose of certain assets. If a Fund failed to qualify as a RIC for a period greater than two taxable years, the Fund would generally be required to recognize any net built-in gains with respect to certain of its assets upon a disposition of such assets within five years of qualifying as a RIC in a subsequent year.

Each Fund intends to distribute at least annually to its shareholders substantially all of its investment company taxable income (computed without regard to the dividends-paid deduction) and net capital gain (the excess of a Fund’s net long-term capital gain over its net short-term capital loss). Investment income that is retained by a Fund will generally be subject to tax at regular corporate rates. If a Fund retains any net capital gain, that gain will be subject to tax at corporate rates, but the Fund may designate the retained amount as undistributed capital gains in a notice to its shareholders who (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their shares of such undistributed amount, (ii) will be deemed to have paid their proportionate shares of the tax paid by the Fund on such undistributed amount against their federal income tax liabilities, if any, and (iii) will be entitled to claim refunds on a properly filed U.S. tax return to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of a Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder.

If a Fund fails to distribute in a calendar year an amount at least equal to the sum of 98% of its ordinary income for such year and 98.2% of its capital gain net income for the one-year period ending October 31 of such year, plus any retained amount from the prior year, the Fund will be subject to a non-deductible 4% excise tax on the undistributed amount. For these purposes, a Fund will be treated as having distributed any amount on which it has been subject to corporate income tax for the taxable year ending within the calendar year. Each Fund intends to declare and pay dividends and distributions in the amounts and at the times necessary to avoid the application of the 4% excise tax, although there can be no assurance that it will be able to do so. Each Fund may in certain circumstances be required to liquidate Fund investments in order to make sufficient distributions to avoid federal excise tax liability at a time when the investment adviser might not otherwise have chosen to do so, and liquidation of investments in such circumstances may affect the ability of such Fund to satisfy the requirement for qualification as a RIC.

calendar year. A “qualified late year loss” generally includes net capital loss, net long-term capital loss, or net short-term capital loss incurred after October 31 of the current taxable year, and certain other late-year losses.

If a Fund has a “net capital loss” (that is, capital losses in excess of capital gains), the excess of the Fund’s net short-term capital losses over its net long-term capital gains is treated as a short-term capital loss arising on the first day of the Fund’s next taxable year, and the excess (if any) of the Fund’s net long-term capital losses over its net short-term capital gains is treated as a long-term capital loss arising on the first day of the Fund’s next taxable year.

“Net capital losses” are not permitted to be deducted against a RIC’s net investment income. Instead, for U.S. federal income tax purposes, potentially subject to certain limitations, a RIC may carry net capital losses from any taxable year forward to offset capital gains in future years. A Fund is permitted to carry net capital losses forward indefinitely. To the extent subsequent capital gains are offset by such losses, they will not result in U.S. federal income tax liability to a Fund and may not be distributed as capital gains to shareholders. Generally, a Fund may not carry forward any losses other than net capital losses. The carryover of capital losses may be limited under the general loss limitation rules if a Fund experiences an ownership change as defined in the Code.

Distributions are generally taxable whether shareholders receive them in cash or reinvest them in additional shares. Moreover, distributions on a Fund’s shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund’s realized income and gains, even though such distributions may economically represent a return of a particular shareholder’s investment. Investors may therefore wish to avoid purchasing shares at a time when the Fund’s NAV reflects gains that are either unrealized, or realized but not distributed. Realized income and gains must generally be distributed even when a Fund’s NAV also reflects unrealized losses.

Dividends and other distributions by a Fund are generally treated under the Code as received by the shareholders at the time the dividend or distribution is made. However, if any dividend or distribution is declared by a Fund in October, November or December of any calendar year and payable to its shareholders of record on a specified date in such a month but is actually paid during the following January, such dividend or distribution will be deemed to have been received by each shareholder on December 31 of the year in which the dividend was declared.

Distributions by the Funds of investment income are generally taxable as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the assets that generated those gains, rather than how long a shareholder has owned his or her Fund shares. Sales of assets held by a Fund for more than one year generally result in long-term capital gains and losses, and sales of assets held by a Fund for one year or less generally result in short-term capital gains and losses. Distributions from a Fund’s net capital gain that are properly reported by the Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable as long-term capital gains. For individuals, long-term capital gains are subject to tax at a maximum tax rate currently set at 20% (lower rates apply to individuals in lower tax brackets). Distributions of gains from the sale of investments that a Fund owned for one year or less will be subject to tax at ordinary income rates.

For non-corporate shareholders, distributions of investment income reported by a Fund as derived from “qualified dividend income” will be taxed at rates of up to 20%, provided holding period and other requirements are met at both the shareholder and Fund level. In order for some portion of the dividends received by a Fund shareholder to be “qualified dividend income,” the Fund making the distribution must meet holding period and other requirements with respect to some portion of the dividend-paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund’s shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date that is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before the ex-dividend date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United

States (with the exception of dividends paid on stock of such a foreign corporation that is readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. Distributions that a Fund receives from an ETF, REIT or an underlying fund taxable as a RIC will be treated as "qualified dividend income" only to the extent so reported by such ETF, REIT or underlying fund.

To the extent that a Fund makes a distribution of income received by the Fund in lieu of dividends (a “substitute payment”) with respect to securities on loan pursuant to a securities lending transaction, such income will not constitute qualified dividend income to individual shareholders and will not be eligible for the dividends received deduction for corporate shareholders.

Dividends and distributions from a Fund and capital gain on the sale of Fund shares are generally taken into account in determining a shareholder’s “net investment income” for purposes of the Medicare contribution tax applicable to certain individuals, estates and trusts.

If a Fund makes distributions in excess of the Fund’s current and accumulated earnings and profits in any taxable year, the excess distribution to each shareholder will be treated as a return of capital to the extent of the shareholder’s tax basis in its shares, and will reduce the shareholder’s tax basis in its shares. After the shareholder’s basis has been reduced to zero, any such distributions will result in a capital gain, assuming the shareholder holds his or her shares as capital assets. A reduction in a shareholder’s tax basis in its shares will reduce any loss or increase any gain on a subsequent taxable disposition by the shareholder of its shares.

A sale or exchange of shares in a Fund may give rise to a gain or loss. In general, any gain or loss realized upon a taxable disposition of shares and will be treated as long-term capital gain or loss if the shares have been held for more than 12 months and short-term capital gain or loss if held for 12 months or less. However, any loss realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, to the extent of any long-term capital gain distributions received (or deemed received) by the shareholder with respect to the shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if substantially identical shares of a Fund are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

The Funds (or financial intermediaries, such as brokers, through which a shareholder holds Fund shares) generally are required to withhold and to remit to the U.S. Treasury a percentage of the taxable distributions and sale or redemption proceeds paid to any shareholder who fails to properly furnish a correct taxpayer identification number, who has under-reported dividend or interest income, or who fails to certify that he, she or it is not subject to such withholding. The backup withholding tax rate is 24%. Backup withholding is not an additional tax. Any amounts withheld may be credited against the shareholder’s U.S. federal income tax liability, provided the appropriate information is furnished to the Internal Revenue Service (the “IRS”).

Transactions of the Funds in options, futures contracts, hedging transactions, forward contracts, swap agreements, straddles and foreign currencies may be subject to various special and complex tax rules, including mark-to-market, constructive sale, straddle, wash sale and short sale rules. These rules could affect a Fund’s ability to qualify as a RIC, affect whether gains and losses recognized by the Fund are treated as ordinary income or capital gain, accelerate the recognition of income to the Fund, and/or defer the Fund’s ability to recognize losses. These rules may in turn affect the amount, timing or character of the income distributed to shareholders by a Fund. These provisions also may require a Fund to mark to market certain types of positions in their portfolios (i.e., treat them as if they were closed out) which may cause the Fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the RIC distribution requirement and for avoiding excise taxes. Accordingly, in order to avoid certain income and excise taxes, a Fund may be required to liquidate its investments at a time when the investment adviser might not otherwise have chosen to do so. The Funds intend to monitor their transactions, intends to make appropriate tax elections, and intend to make appropriate entries in their books and records in order to mitigate the effect of these rules and preserve their qualification for treatment as RICs.

The Funds are required, for federal income tax purposes, to mark to market and recognize as income for each taxable year its net unrealized gains and losses as of the end of such year on certain regulated futures contracts, foreign currency contracts and options that qualify as Section 1256 contracts in addition to the gains and losses actually realized with respect to such contracts during the year. Gain or loss from Section 1256 contracts that are required to be marked to market annually will generally be 60% long-term and 40% short-term capital gain or loss. Application of this rule may alter the timing and character of distributions to shareholders. The Funds may be required to defer the recognition of losses on futures contracts, options contracts and swaps to the extent of any unrecognized gains on offsetting positions held by the Fund. These provisions may also require the Funds to mark-to-market certain types of positions in their portfolios (i.e., treat them as if they were closed out), which may cause a Fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the Distribution Requirement and for avoiding the excise tax discussed above.

The Funds may invest in REITs. Investments in REIT equity securities may require a Fund to accrue and distribute income not yet received. To generate sufficient cash to make the requisite distributions, a Fund may be required to sell securities in its portfolio (including when it is not advantageous to do so) that it otherwise would have continued to hold. A Fund’s investments in REIT equity securities may at other times result in a Fund’s receipt of cash in excess of the REIT’s earnings; if a Fund distributes these amounts, these distributions could constitute a return of capital to a Fund’s shareholders for federal income tax purposes. Dividends paid by a REIT, other than capital gain distributions, will be taxable as ordinary income up to the amount of the REIT’s current and accumulated earnings and profits. Capital gain dividends paid by a REIT to a Fund will be treated as long-term capital gains by a Fund and, in turn, may be distributed by a Fund to its shareholders as a capital gain distribution. Dividends received by a Fund from a REIT generally will not constitute qualified dividend income or qualify for the dividends received deduction. If a REIT is operated in a manner such that it fails to qualify as a REIT, an investment in the REIT would become subject to double taxation, meaning the taxable income of the REIT would be subject to federal income tax at regular corporate rates without any deduction for dividends paid to shareholders and the dividends would be taxable to shareholders as ordinary income (or possibly as qualified dividend income) to the extent of the REIT’s current and accumulated earnings and profits.

A Fund may invest in REITs that hold residual interests in real estate mortgage investment conduits (“REMICs”) or which are, or have certain wholly-owned subsidiaries that are, “taxable mortgage pools” (“TMPs”). Under certain Treasury guidance, a portion of a Fund’s income from a REIT that is attributable to the REIT’s residual interest in a REMIC or equity interests in a TMP (referred to in the Code as an “excess inclusion”) will be subject to federal income tax in all events. This guidance provides that excess inclusion income of a RIC, such as a Fund, must generally be allocated to shareholders of the RIC in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related REMIC residual interest or TMP interests directly. In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on unrelated business income, thereby potentially requiring such an entity, which otherwise might not be required to file a tax return, to file a tax return and pay tax on such income (see “Taxes—Tax-Exempt Shareholders” below), and (iii) in the case of a foreign shareholder, will not qualify for any reduction in U.S. federal withholding tax. A Fund does not intend to invest a substantial portion of its assets in REITs which generate excess inclusion income.

REITs in which a Fund invests often do not provide complete and final tax information to a Fund until after the time that a Fund issues a tax reporting statement. As a result, a Fund may at times find it necessary to reclassify the amount and character of its distributions after it issues a tax reporting statement. If this were to occur, the financial intermediary with whom you hold your shares will send you a corrected, final Form 1099-DIV to reflect the reclassified information. If you receive a corrected Form 1099-DIV, use the information on this corrected form, and not the information on the previously issued tax reporting statement, in completing your tax returns.

average fair market value) either produce or are held for the production of passive income (“passive foreign investment companies” or “PFICs”), the Funds will generally be subject to one of the following special tax regimes: (i) a Fund may be liable for U.S. federal income tax, and an additional interest charge, on a portion of any “excess distribution” from such foreign entity or any gain from the disposition of such shares, even if the entire distribution or gain is paid out by the Fund as a dividend to its shareholders; (ii) if a Fund were able and elected to treat a PFIC as a “qualified electing fund” or “QEF,” the Fund would be required each year to include in income, and distribute to shareholders in accordance with the distribution requirements set forth above, the Fund’s pro rata share of the ordinary earnings and net capital gains of the PFIC, whether or not such earnings or gains are distributed to the Fund; or (iii) a Fund may be entitled to mark-to-market annually shares of the PFIC, and in such event would be required to distribute to shareholders any such mark-to-market gains in accordance with the distribution requirements set forth above. The Funds intend to make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effect of these rules. The Funds may limit and/or manage their holdings in passive foreign investment companies to limit their tax liability or maximize their return from these investments.

Income received by the Funds from sources within foreign countries (including, for example, dividends or interest on stock or securities of non-U.S. issuers) may be subject to withholding and other taxes imposed by such countries. Tax treaties between such countries and the U.S. may reduce or eliminate such taxes.

Under current law, income of a RIC that would be treated as unrelated business taxable income (“UBTI”) if earned directly by a tax-exempt entity generally will not be attributed as UBTI to a tax-exempt entity that is a shareholder in the RIC. Notwithstanding this “blocking” effect, a tax-exempt shareholder could realize UBTI by virtue of its investment in a Fund if: (i) shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Code Section 514(b), (ii) if the Fund invests in REITs that hold residual interests in REMICs, (iii) the Fund invests in a REIT that is a taxable mortgage pool (“TMP”) or in a REIT that has a subsidiary that is a TMP, or (iv) if the Fund holds residual interests in REMICs. The IRS has issued guidance with respect to these issues and prospective shareholders, especially charitable remainder trusts, are strongly encouraged to consult their tax advisors regarding these issues. The Funds are not expected to hold any REMIC interests.

In general, dividends, other than Capital Gain Dividends paid by the Funds to a shareholder that is not a “U.S. person” within the meaning of the Code are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) on distributions derived from taxable ordinary income. The Funds may, under certain circumstances, report all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met. Short-term capital gain dividends received by a nonresident alien individual who is present in the U.S. for a period or periods aggregating 183 days or more during the taxable year are not exempt from this 30% withholding tax.

A beneficial holder of shares who is a non-U.S. person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a U.S. income tax deduction for losses) realized on a sale of shares of a Fund or on Capital Gain Dividends unless (i) such gain or dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States or (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or the receipt of the Capital Gain Dividend and certain other conditions are met.

Unless certain non-U.S. entities that hold Fund shares comply with IRS requirements that generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to Fund distributions payable to such entities and may apply to redemptions and certain capital gain dividends payable to such entities after December 31, 2018. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of the agreement.

trade or business will generally be subject to U.S. federal income tax on a net basis only if it is also attributable to a permanent establishment maintained by the shareholder in the United States.

An Authorized Participant having the U.S. dollar as its functional currency for U.S. federal income tax purposes that exchanges securities for Creation Units generally will recognize a gain or loss equal to the difference between (i) the sum of the market value of the Creation Units at the time of the exchange and any cash received by the Authorized Participant in the exchange, and (ii) the sum of the exchanger’s aggregate basis in the securities surrendered and any cash paid for such Creation Units. Any gain or loss realized upon the creation of Creation Units will generally be treated as long-term capital gain or loss if the securities exchanged for such Creation Units have been held for more than one year and were held as capital assets in the hands of the exchanging Authorized Participant. All or a portion of any gain or loss recognized by an Authorized Participant exchanging a currency other than its functional currency for Creation Units may be treated as ordinary income or loss. A person who redeems Creation Units will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate U.S. dollar market value of any securities received plus the amount of any cash received for such Creation Units. The ability of Authorized Participants to receive a full or partial cash redemption of Creation Units of a Fund may limit the tax efficiency of the Fund. The IRS, however, may assert that a loss that is realized upon an exchange of securities for Creation Units may not be currently deducted under the rules governing “wash sales” (for a person who does not mark-to-market its holdings), or on the basis that there has been no significant change in economic position. All or some portion of any capital gain or loss realized upon the creation of Creation Units in exchange for securities will generally be treated as long-term capital gain or loss if securities exchanged for such Creation Units have been held for more than one year.

Any capital gain or loss realized upon the redemption of Creation Units will generally be treated as long-term capital gain or loss if the shares comprising the Creation Units have been held for more than one year. Otherwise, such capital gains or losses will be treated as short-term capital gains or losses.

The Trust on behalf of the Funds has the right to reject an order for a purchase of shares of a Fund if the purchaser (or any group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to Section 351 of the Code, a Fund would have a basis in the securities different from the market value of such securities on the date of deposit. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination. If a Fund does issue Creation Units to a purchaser (or a group of purchasers) that would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of the Fund, the purchaser (or a group of purchasers) may not recognize gain or loss upon the exchange of securities for Creation Units.

Under U.S. Treasury regulations, generally, if a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder (or certain greater amounts over a combination of years), the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a RIC are not excepted. Significant penalties may be imposed for the failure to comply with the reporting regulations. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

The cost basis of shares acquired by purchase will generally be based on the amount paid for the shares and then may be subsequently adjusted for other applicable transactions as required by the Code. The difference between the selling price and the cost basis of shares generally determines the amount of the capital gain or loss realized on the sale or exchange of shares. Contact the broker through whom you

purchased your shares to obtain information with respect to the available cost basis reporting methods and elections for your account.

The federal income tax discussion set forth above is for general information only. Prospective investors should consult their tax advisors regarding the specific federal income tax consequences of purchasing, holding and disposing of shares of the Funds, as well as the effect of state, local and foreign tax law and any proposed tax law changes.

Each Fund intends to pay out dividends, if any, on an annual basis, except for the Nuveen ESG Dividend ETF, which intends to pay out dividends quarterly. Nonetheless, the Funds might not make a dividend payment every month. Each Fund intends to distribute its net realized capital gains, if any, to investors annually. The Funds may occasionally be required to make supplemental distributions at some other time during the year. Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available. Your broker is responsible for distributing the income and capital gain distributions to you.

The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve the status of a Fund as a RIC or to avoid imposition of income or excise taxes on undistributed income.

General Policy: We generally vote in favor of the board’s nominees but will consider withholding or voting against some or all directors in the following circumstances:

· When we conclude that the actions of directors are unlawful, unethical, negligent, or do not meet fiduciary standards of care and loyalty, or are otherwise not in the best interest of shareholders. Such actions would include:

· When a director has consistently failed to attend board and committee meetings without an appropriate rationale being provided

· When board independence is not in line with local market regulations or best practices

· When a member of executive management sits on a key board committee that should be composed of only independent directors

· When directors have failed to disclose, resolve or eliminate conflicts of interest that affect their decisions

· When we determine that director tenure is excessive and there has been no recent board refreshment

General Policy: We generally support shareholder resolutions asking that companies amend their governance documents to provide for director election by majority vote.

General Policy: We generally vote against shareholder resolutions asking the company to establish specific board committees unless we believe specific circumstances dictate otherwise.

General Policy: We generally support shareholder resolutions asking that each member of the board of a publicly traded operating company stand for re-election annually.

General Policy: We generally do not support proposals asking that shareholders be allowed to cumulate votes in director elections, as this practice may encourage the election of special interest directors.

General Policy: We will generally support the board’s choice of auditor and believe that the auditor should be elected annually. However, we will consider voting against the ratification of an audit firm where non-audit fees are excessive, where the firm has been involved in conflict of interest or fraudulent activities in connection with the company’s audit, where there has been a material restatement of financials or where the auditor’s independence is questionable.

General Policy: We will generally support shareholder resolutions asking for the elimination of supermajority vote requirements.

General Policy: We will generally support shareholder resolutions asking for the elimination of dual classes of common stock or other forms of equity with unequal voting rights or special privileges.

General Policy: We will generally support shareholder resolutions asking for the right to call a special meeting. However, we believe a 25% ownership level is reasonable and generally would not be supportive of proposals to lower the threshold if it is already at that level.

General Policy: We will consider on a case-by-case basis shareholder resolutions requesting the right to act by written consent.

General Policy: We will consider on a case-by-case basis proposals relating to the adoption or rescission of antitakeover devices with attention to the following criteria:

· Whether the provisions of the device are in line with generally accepted governance principles

· Whether the proposal arises in the context of a takeover bid or contest for control

We will generally support shareholder resolutions asking to rescind or put to a shareholder vote antitakeover devices that were adopted without shareholder approval.

· We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to a company’s direct political contributions, including board oversight procedures.

· We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to a company’s charitable contributions and other philanthropic activities.

· We will evaluate on a case-by-case basis shareholder resolutions seeking disclosure of a company’s lobbying expenditures.

General Policy: We will consider on a case-by-case basis the advisory vote on executive compensation (say on pay). We expect well-designed plans that clearly demonstrate the alignment between pay and performance, and we encourage companies to be responsive to low levels of support by engaging with shareholders. We also prefer that companies offer an annual non-binding vote on executive compensation. In absence of an annual vote, companies should clearly articulate the rationale behind offering the vote less frequently.

We generally note the following red flags when evaluating executive compensation plans:

· Undisclosed or Inadequate Performance Metrics: We believe that performance goals for compensation plans should be disclosed meaningfully. Performance hurdles should not be too easily attainable. Disclosure of these metrics should enable shareholders to assess whether the plan will drive long-term value creation.

· Excessive Equity Grants: We will examine a company’s past grants to determine the rate at which shares are being issued. We will also seek to ensure that equity is being offered to more than just the top executives at the company. A pattern of excessive grants can indicate failure by the board to properly monitor executive compensation and its costs.

· Lack of Minimum Vesting Requirements: We believe that companies should establish minimum vesting guidelines for senior executives who receive stock grants. Vesting requirements help influence executives to focus on maximizing the company’s long-term performance rather than managing for short-term gain.

· Misalignment of Interests: We support equity ownership requirements for senior executives and directors to align their interests with those of shareholders.

· Special Award Grants: We will generally not support mega-grants. A company’s history of such excessive grant practices may prompt us to vote against the stock plans and the directors who approve them. Mega-grants include equity grants that are excessive in relation to other forms of compensation or to the compensation of other employees and grants that transfer disproportionate value to senior executives without relation to their performance. We also expect companies to provide a rationale for any other one-time awards such as a guaranteed bonus or a retention award.

· Excess Discretion: We will generally not support plans where significant terms of awards—such as coverage, option price, or type of awards—are unspecified, or where the board has too much discretion to override minimum vesting or performance requirements.

· Lack of Clawback Policy: We believe companies should establish clawback policies that permit recoupment from any senior executive who received compensation as a result of defective financial reporting, or whose behavior caused financial harm to shareholders or reputational risk to the company.

General Policy: We will review equity-based compensation plans on a case-by-case basis, giving closer scrutiny to companies where plans include features that are not performance-based or where potential dilution or burn rate total is excessive. As a practical matter, we recognize that more dilutive broad-based plans may be appropriate for human-capital intensive industries and for small- or mid-capitalization firms and start-up companies.

We generally note the following red flags when evaluating equity incentive plans:

· Evergreen Features: We will generally not support option plans that contain evergreen features, which reserve a specified percentage of outstanding shares for award each year and lack a termination date.

· Reload Options: We will generally not support reload options that are automatically replaced at market price following exercise of initial grants.

· Repricing Options: We will generally not support plans that authorize repricing. However, we will consider on a case-by-case basis management proposals seeking shareholder approval to reprice options. We are likely to vote in favor of repricing in cases where the company excludes

named executive officers and board members and ties the repricing to a significant reduction in the number of options.

· Undisclosed or Inappropriate Option Pricing: We will generally not support plans that fail to specify exercise prices or that establish exercise prices below fair market value on the date of grant.

General Policy: We will vote on a case-by-case basis on golden parachute proposals, taking into account the structure of the agreement and the circumstances of the situation. However, we would prefer to see a double trigger on all change-of-control agreements and no excise tax gross-up.

General Policy: We will consider on a case-by-case basis shareholder resolutions related to specific compensation practices. Generally, we believe specific practices are the purview of the board.

General Policy: We will generally support reasonable shareholder resolutions seeking disclosure of greenhouse gas emissions, the impact of climate change on a company’s business activities and products and strategies designed to reduce the company’s long-term impact on the global climate.

General Policy: We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to a company’s use of natural resources, the impact on its business of declining resources and its plans to improve the efficiency of its use of natural resources.

General Policy: We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to a company’s initiatives to reduce any harmful impacts or other hazards to local, regional or global ecosystems that result from its operations or activities.

General Policy: We will generally support reasonable shareholder resolutions asking for reports on the company’s impact on animal welfare.

General Policy: We will generally support reasonable shareholder resolutions seeking disclosure relating to the quality, safety and impact of a company’s goods and services on the customers and communities it serves.

General Policy: We will generally support reasonable shareholder resolutions asking companies for disclosure about the impact of lending activities on borrowers and about policies designed to prevent predatory lending practices.

· We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to a company’s nondiscrimination policies and practices, or seeking to implement such policies, including equal employment opportunity standards.

· We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to a company’s workforce, board diversity, and gender pay equity policies and practices.

General Policy: We will generally support reasonable shareholder resolutions seeking a review of a company’s labor standards and enforcement practices, as well as the establishment of global labor policies based upon internationally recognized standards.

General Policy: We will generally support reasonable shareholder resolutions seeking disclosure or reports relating to significant public health impacts resulting from company operations and products, as well as the impact of global health pandemics on the company’s operations and long-term growth.

General Policy: We will generally support reasonable shareholder resolutions seeking a review of a company’s human rights standards and the establishment of global human rights policies, especially regarding company operations in conflict zones or areas of weak governance.

(1) Concentrate its investments in a particular industry, as the term “concentrate” is used in the 1940 Act, except as may be necessary to approximate the composition of its Index.

(2) Borrow money or issue senior securities, except as permitted under the 1940 Act, as interpreted or modified from time to time by any regulatory authority having jurisdiction.

(7) Make loans, except as permitted under the 1940 Act, as interpreted or modified from time to time by any regulatory authority having jurisdiction.

Each foreign government will be considered to be a member of a separate industry.

(1) Acquire any securities of registered open-end investment companies or registered unit investment trusts in reliance on subparagraph (F) or subparagraph (G) of Section 12(d)(1) of the 1940 Act.

Each Fund has adopted a non-fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (the “Name Policy”) whereby the Fund, under normal market conditions, will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of its Index. As a result, each of these Funds must provide shareholders with a notice, meeting the requirements of Rule 35d-1(c), at least 60 days prior to any change of its Name Policy. For purposes of the Name Policy, each Fund may consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, the Funds will value eligible derivatives at fair value or market value instead of notional value. If, subsequent to an investment, the 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

References in this section to the Adviser also apply, to the extent applicable, to the Sub-Adviser of the Funds.

are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association, whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. In addition, each Fund may invest in sovereign debt obligations of non-U.S. countries. U.S. Treasury obligations include separately traded interest and principal component parts of such obligations, known as Separately Traded Registered Interest and Principal Securities (“STRIPS”), which are transferable through the Federal book-entry system. STRIPS are sold as zero coupon securities, which means that they are sold at a substantial discount and redeemed at face value at their maturity date without interim cash payments of interest or principal. This discount is accreted over the life of the security, and such accretion will constitute the income earned on the security for both accounting and tax purposes. Because of these features, such securities may be subject to greater interest rate volatility than interest paying U.S. Treasury obligations.

managers do so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

same way as the Fund can increase or decrease the level of risk, or change the character of the risk, of its portfolio by making investments in specific securities. However, derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on a Fund’s performance.

option or the closing price of the index and the exercise price of the option expressed in dollars times a specified multiple (the “multiplier”). The writer of the option is obligated, for the premium received, to make delivery of this amount. Settlements for interest rate and index options are always in cash.

Most U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of futures contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

Each Fund may enter into interest rate, total return, and credit default swap agreements.

value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

be amended from time to time. Under Rule 4.5 as currently in effect, each Fund will limit its trading activity in CFTC Derivatives (excluding activity for “bona fide hedging purposes,” as defined by the CFTC) such that it meets one of the following tests:

The use of derivative instruments involves certain general risks and considerations as described below.

(3) Correlation Risk. Correlation risk is the risk that there might be an imperfect correlation, or even no correlation, between price movements of a derivative instrument and price movements of investments being hedged. When a derivative transaction is used to completely hedge another position, changes in the market value of the combined position (the derivative instrument plus the position being hedged) result from an imperfect correlation between the price movements of the two instruments. With a perfect hedge, the value of the combined position remains unchanged with any change in the price of the underlying asset. With an imperfect hedge, the value of the derivative instrument and its hedge are not perfectly correlated. For example, if the value of a derivative instrument used in a short hedge (such as a CDS) increased by less than the decline in value of the hedged investments, the hedge would not be perfectly correlated. This might occur due to factors unrelated to the value of the investments being

hedged, such as speculative or other pressures on the markets in which these instruments are traded. The effectiveness of hedges using instruments on indices will depend, in part, on the degree of correlation between price movements in the index and the price movements in the investments being hedged.

Under normal market conditions, the Funds primarily invest in equity securities, which include common stocks, preferred securities, warrants to purchase common stocks or preferred securities,

convertible securities, participatory notes, interests in real estate investment trusts, common and preferred units of master limited partnerships, and other securities with equity characteristics.

Stock markets tend to move in cycles with short or extended periods of rising and falling stock prices. The value of a company’s stock may fall because of:

· Factors that directly relate to that company, such as decisions made by its management or lower demand for the company’s products or services;

· Factors affecting an entire industry, such as increases in production costs; and

· Changes in financial market conditions that are relatively unrelated to the company or its industry, such as changes in interest rates, currency exchange rates or inflation rates.

may be converted within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. They also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Convertible securities entitle the holder to receive interest paid or accrued on debt, or dividends paid or accrued on preferred securities, until the security matures or is redeemed, converted or exchanged.

The Funds may invest in participatory notes issued by banks or broker-dealers that are designed to replicate the performance of certain non-U.S. companies traded on a non-U.S. exchange. Participatory notes are a type of equity-linked derivative which generally are traded over-the-counter. Even though a participatory note is intended to reflect the performance of the underlying equity securities on a one-to-one basis so that investors will not normally gain or lose more in absolute terms than they would have made or lost had they invested in the underlying securities directly, the performance results of participatory notes will not replicate exactly the performance of the issuers or markets that the notes seek to replicate due to transaction costs and other expenses. Investments in participatory notes involve risks normally associated with a direct investment in the underlying securities. In addition, participatory notes are subject to counterparty risk, which is the risk that the broker-dealer or bank that issues the notes will not fulfill its contractual obligation to complete the transaction with a Fund. Participatory notes constitute general unsecured, unsubordinated contractual obligations of the banks or broker-dealers that issue them, and a Fund is relying on the creditworthiness of such banks or broker-dealers and has no rights under a participatory note against the issuers of the securities underlying such participatory notes. There

can be no assurance that the trading price or value of participatory notes will equal the value of the underlying value of the equity securities they seek to replicate.

The Funds will invest primarily in equity securities issued by non-U.S. companies. Investments in securities of non-U.S. companies involve risks in addition to the usual risks inherent in domestic investments, including currency risk. The value of a non-U.S. security in U.S. dollars tends to decrease when the value of the U.S. dollar rises against the non-U.S. currency in which the security is denominated and tends to increase when the value of the U.S. dollar falls against such currency.

Non-U.S. securities are affected by the fact that in many countries there is less publicly available information about issuers than is available in the reports and ratings published about companies in the United States and such issuers may not be subject to uniform accounting, auditing and financial reporting standards. Other risks inherent in non-U.S. investments include expropriation; confiscatory taxation; withholding taxes on dividends and interest; less extensive regulation of non-U.S. brokers, securities markets and issuers; diplomatic developments; and political or social instability. Non-U.S. economies may differ favorably or unfavorably from the U.S. economy in various respects, and many non-U.S. securities are less liquid and their prices tend to be more volatile than comparable U.S. securities. From time to time, non-U.S. securities may be difficult to liquidate rapidly without adverse price effects.

The Funds may also invest in non-U.S. securities by purchasing depositary receipts, including American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”), Global Depositary Receipts (“GDRs”) or other securities representing indirect ownership interests in the securities of non-U.S. companies, including New York Shares. Generally, ADRs, in registered form, are denominated in U.S. dollars and are designated for use in the U.S. securities markets, while EDRs and GDRs are typically in bearer form and may be denominated in non-U.S. currencies and are designed for use in European and other markets. ADRs are receipts typically issued by a U.S. bank or trust company evidencing ownership of the underlying non-U.S. security. ADRs, EDRs and GDRs are deemed to have the same classification as the underlying securities they represent, except that ADRs, EDRs and GDRs shall be treated as indirect non-U.S. investments. Thus, an ADR, EDR or GDR representing ownership of common stock will be treated as common stock. ADRs, EDRs and GDRs do not eliminate all of the risks associated with directly investing in the securities of non-U.S. companies, such as changes in non-U.S. currency exchange rates. However, by investing in ADRs rather than directly in non-U.S. companies’ stock, a Fund avoids currency risks during the settlement period.

Other types of depositary receipts include American Depositary Shares (“ADSs”), Global Depositary Certificates (“GDCs”) and International Depositary Receipts (“IDRs”). ADSs are shares issued under a deposit agreement representing the underlying ordinary shares that trade in the issuer’s home market. An ADR, described above, is a certificate that represents a number of ADSs. GDCs and IDRs are typically issued by a non-U.S. bank or trust company, although they may sometimes also be issued by a U.S. bank or trust company. GDCs and IDRs are depositary receipts that evidence ownership of underlying securities issued by either a non-U.S. or a U.S. corporation.

Depositary receipts may be available through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by a depositary and the issuer of the security underlying the receipt. An unsponsored facility may be established by a depositary without participation by the issuer of the security underlying the receipt. There are greater risks associated with holding unsponsored depositary receipts. For example, if a Fund holds an unsponsored depositary receipt, it will generally bear all of the costs of establishing the unsponsored facility. In addition, the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited security. Whether a sponsored or unsponsored facility, there is no assurance that either would pass through to the holders of the receipts voting rights with respect to the deposited securities.

In considering whether to invest in the securities of a non-U.S. company, the portfolio managers consider such factors as the characteristics of the particular company, differences between economic trends, and the performance of securities markets in the United States and other countries. The portfolio managers also consider factors relating to the general economic, governmental and social conditions of the country or countries where the company is located.

Securities transactions conducted outside the United States may not be regulated as rigorously as in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, non-U.S. securities, currencies and other instruments. The value of such positions also could be adversely affected by (i) other complex non-U.S. political, legal and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) the imposition of different exercise and settlement terms and procedures and the margin requirements than in the United States, and (iv) currency exchange rate changes, and lower trading volume and liquidity.

The ramifications of the hostilities and sanctions, however, may not be limited to Russia and Russian companies but may spill over to and negatively impact other regional and global economic markets (including Europe and the United States), companies in other countries (particularly those that have done business with Russia) and on various sectors, industries and markets for securities and commodities globally, such as oil and natural gas. Accordingly, the actions discussed above and the potential for a wider conflict could increase financial market volatility, cause severe negative effects on regional and global economic markets, industries, and companies and have a negative effect on your Fund’s investments and performance beyond any direct exposure to Russian issuers or those of adjoining geographic regions. In addition, Russia may take retaliatory actions and other countermeasures, including cyberattacks and espionage against other countries and companies around the world, which may negatively impact such countries and the companies in which your Fund invests.

The extent and duration of the military action or future escalation of such hostilities, the extent and impact of existing and future sanctions, market disruptions and volatility, and the result of any diplomatic negotiations cannot be predicted. These and any related events could have a significant impact on Fund performance and the value of an investment in the Fund, particularly with respect to Russian exposure.

The Funds may invest in securities issued by companies located in emerging markets. Emerging market countries are generally in the initial stages of their industrialization cycles with low per capita income. The markets of emerging markets countries are generally more volatile than the markets of developed countries with more mature economies. They generally do not have the level of market efficiency and strict standards in accounting and securities regulation to be on par with advanced economies, but emerging markets will typically have a physical financial infrastructure, including banks, a stock exchange and a unified currency. Investors may also have limited rights relative to companies domiciled in emerging market countries, and investors may be unable to pursue the same avenues of recourse available to investors of U.S. companies, such as class action lawsuits and fraud claims, either as a matter of law or practicality. Investments in emerging markets come with much greater risk due to political instability, domestic infrastructure problems, currency volatility and limited investment opportunities (many large companies may still be “state-run” or private). Also, local securities exchanges may not offer liquid markets for outside investors. All of the risks of investing in non-U.S. securities described above are heightened by investing in emerging markets countries.

In addition, some countries in which the Funds may invest have experienced substantial, and in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of certain countries. Further, the economies of emerging market countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

The risks outlined above are often more pronounced in “frontier markets” in which a Fund may invest. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets. This magnification of risks is the result of a number of factors, including: government ownership or control of parts of the private sector and of certain companies; trade barriers; exchange controls; managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; less uniformity in accounting and reporting requirements; unreliable securities valuation; greater risk associated with custody of securities; and the relatively new and unsettled securities laws in many frontier market countries. In addition, the markets of frontier countries typically have low trading volumes, leading to a greater potential for extreme price volatility and illiquidity. This volatility may be further increased by the actions of a few large investors. For example, a substantial increase or decrease in cash flows of mutual funds investing in these markets could significantly affect local securities prices and, therefore, the NAV of a Fund. All of these factors may make investing in frontier market countries significantly riskier than investing in other countries, including more developed and traditional emerging market countries, and any one of them could cause the NAV of a Fund’s shares to decline.

The EU is an intergovernmental and supra-national union of certain European countries, known as member states. A key activity of the EU is the establishment and administration of a common single market, consisting of, among other things, a single currency and a common trade policy. The most widely used currency in the EU (and the unit of currency of the European Economic and Monetary Union (“EMU”)) is the euro, which is in use in many of the member states. In addition to adopting a single currency, EMU member states generally no longer control their own monetary policies. Instead, the authority to direct monetary policy is exercised by the European Central Bank and, as a result, EMU member states are significantly affected by fiscal and monetary policies implemented by the EMU and European Central Bank.

While economic and monetary convergence in the EU may offer new opportunities for those investing in the region, investors should be aware that the success of the EU is not wholly assured. Europe must grapple with a number of challenges, any one of which could threaten the survival of this

monumental undertaking. Many disparate economies continue to adjust to a unified monetary system, the absence of exchange rate flexibility, and the loss of economic sovereignty. Europe’s economies are diverse, its governments are decentralized, and its cultures differ widely. As member states unify their economic and monetary policies, movements in European markets will lose the benefit of diversification within the region. High unemployment could pose political risk. One or more member states might exit the union, placing the currency and banking system in jeopardy. Major issues currently facing the EU relate to its membership, structure, procedures and policies; they include the adoption, abandonment or adjustment of the constitutional treaty, the EU’s enlargement to the south and east, and resolving the EU’s problematic fiscal and democratic accountability. Any or all of these challenges may affect the value of a Fund’s investments economically tied to the EU.

The EU has been extending its influence to the south and east. For former Iron Curtain member states, membership serves as a strong political impetus to employ tight fiscal and monetary policies. Nevertheless, several entrants in recent years are former Soviet satellites that remain burdened to various extents by the inherited inefficiencies of centrally planned economies similar to that which existed under the old Soviet Union.

In addition, certain member states in the EU have had to accept assistance from supra-governmental agencies such as the International Monetary Fund and the European Financial Stability Facility. The European Central Bank has also intervened to purchase eurozone debt in order to seek to stabilize markets and reduce borrowing costs. Responses to these financial problems by European governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest, and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world.

The EU’s economy is expected to grow further over the next decade as more countries join. However, the EU’s economic growth has been below that of the United States most years since 1990, and the economic performance of certain of its key members is a matter of serious concern to policy makers. Although economic conditions vary among EU member states, there is continued concern about national level support for the euro and the accompanying coordination of fiscal and wage policy of EU member states.

In addition, many EU members suffered severe economic declines during and after the 2008–2009 worldwide economic downturn. These declines led to fiscal crises for the governments of certain members including Portugal, Ireland, Italy, Greece and Spain. Some EU member states required external assistance to meet their obligations, and all of these member states run the risk of default on their debt, possible bailout by the rest of the EU or debt restructuring, which may require creditors to bear losses. These events adversely affected the exchange rate of the euro and may continue to significantly affect every country in Europe, including countries that do not use the euro. Certain of the larger European economies have shown limited signs of recovery from the 2008–2009 worldwide economic downturn; however, significant risks still threaten the potential recovery, such as high official debts and deficits, aging populations, over-regulation of non-financial businesses and doubts about the sustainability of the EMU. These countries will need to make certain economic and political decisions in order to restore sustainable economic growth and fiscal policy. While many initiatives have been instituted to strengthen regulation and supervision of financial markets in the EU, greater regulation is expected in the future.

Further, it is possible that the euro could be abandoned in the future by EU member states that have already adopted its use, and the effects of such an abandonment or a member state’s forced expulsion from the euro on that member state, on the EMU, and on global markets are impossible to predict and could be negative. The exit of any member state out of the euro would likely have a significant destabilizing effect on all eurozone countries and their economies and a negative effect on the global economy as a whole. In addition, under these circumstances, it may be difficult to value investments denominated in euros or in a replacement currency.

The impact of the UK’s withdrawal on the UK and European economies and the broader global economy could be significant, resulting in negative impacts, such as increased volatility and illiquidity, potentially lower economic growth and decreased asset valuations. The UK’s withdrawal from the EU may have a destabilizing impact on the EU to the extent other member states similarly seek to withdraw from the union and may cause additional market disruption globally and introduce new legal and regulatory uncertainties. It may also have a negative impact on the economy and currency of the UK as a result of anticipated, perceived or actual changes to the UK’s economic and political relations with the EU. The UK’s withdrawal could result in lower growth for companies in the UK, EU and globally, which could have an adverse effect on the value of a Fund’s investments. A Fund may make investments in the UK (during the transition period and afterwards), other EU members and in non-EU countries that are directly or indirectly affected by the exit of the UK from the EU. Any or all of these challenges may affect the value of a Fund’s investments economically tied to the UK or EU and may have an adverse effect on the Fund’s performance. Additionally, the willingness or ability of financial and other counterparties to enter into transactions may be affected by the UK’s withdrawal.

Investments in Indian issuers may exhibit significantly greater market volatility than investments in issuers from more developed markets due to India's unique legal, regulatory, political, currency and economic risks. Such investments are subject to political and legal uncertainty, greater government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets. The Indian government has exercised, and continues to exercise, significant influence over many aspects of the Indian economy, and the number of public sector enterprises in India is substantial. Although the government has recently begun to institute economic reform policies, there can be no assurance that it will continue to pursue such policies, or, if it does, that such policies will succeed. These risks, among others, may result in higher potential losses for the Fund as well as higher transaction costs.

The limited liquidity of the Indian securities markets, which is characterized by a small number of listed companies that have significantly smaller market capitalizations, may also affect the Fund's ability to acquire or dispose of Indian securities at the price and time that the Fund desires. In addition, the laws relating to limited liability of corporate shareholders, fiduciary duties of officers and directors, and the bankruptcy of state enterprises are generally less well developed than, or different from, U.S. laws. These factors, coupled with the lack of extensive accounting, auditing and financial reporting standards and practices, as compared to the United States, may increase the Fund's risk of loss with respect to its investments in India.

While the government of India is moving to a more liberal approach, it still places restrictions on the capability and capacity of foreign investors to access and trade rupee directly. Foreign investors may face restrictions on their investment opportunities in India, including limits on foreign ownership imposed by the Reserve Bank of India ("RBI"). Further, certain Indian regulatory approvals, including approvals from the Securities and Exchange Board of India ("SEBI"), the RBI, the central government, and the tax authorities (to the extent that tax benefits need to be utilized), may be required before the Fund can make investments in the securities of Indian companies. Capital gains from Indian securities may be subject to local taxation.

India has also privatized, or is in the process of privatizing, certain government-sponsored entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment, compete against government-sponsored entities that have not been privatized, or adapt to changing regulatory and legal standards. In some cases, investors incurred losses when India re-nationalized newly privatized companies. There is no assurance that similar losses will not take place again in the future.

Moreover, in the recent past, India has experienced civil unrest, religious conflicts, border disputes and hostilities with neighboring countries, including Pakistan, and terrorist threats from separatist movements in several Indian states. Incidents involving India's or the region's security may cause uncertainty in the Indian market and may adversely affect the Indian economy and the Fund's investments. In addition, natural disasters, such as tsunamis, flooding or droughts, could occur in India or surrounding areas and negatively impact the Indian economy or the operations of Indian companies, which, in turn, could negatively affect the Fund.

Government-industry cooperation, a strong work ethic, mastery of high technology, emphasis on education, and a comparatively small defense allocation helped Japan advance with extraordinary speed to become one of the largest economic powers along with the United States and the EU. Despite its impressive history, investors face special risks when investing in Japan.

The growth of Japan’s economy has recently lagged that of its Asian neighbors and other major developed countries. Since the early 2000s, Japan’s economic growth rate has remained low relative to other advanced economies and may remain low in the future. The Japanese economy is heavily reliant on international trade and has been adversely affected in the past by trade tariffs, other protectionist measures, competition from emerging economies, and the economic conditions of its trading partners. In addition, China has become an important trading partner with Japan. Japan’s political relationship with China, however, is strained and delicate. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole. Japan is also heavily dependent on oil and other commodity imports, and higher commodity prices could therefore have a negative impact on the Japanese economy. Although Japan has recently worked to reduce its dependence on oil by encouraging energy conservation and the use of alternative fuels, there is no guarantee that this trend will continue. The yen has had a history of unpredictable and volatile movements against the U.S. dollar; a weakening yen hurts U.S. investors holding yen-denominated securities. The Japanese stock market has also experienced wild swings in value over time and has often been considered significantly overvalued.

Beginning in the late 1990s, the nation’s financial institutions were successfully overhauled under the strong leadership of the government. The successful financial sector reform coincided with a Japanese economic recovery, which had set the stage for a comparatively brighter outlook for Japanese companies. However, Japan has an aging workforce and has experienced a significant population decline in recent years. Japan’s labor market appears to be undergoing fundamental structural changes, as a labor market traditionally accustomed to lifetime employment adjusts to meet the need for increased labor mobility, which may affect Japan’s economic competitiveness.

Japan is susceptible to natural disasters such as earthquakes and tsunamis, and a Fund’s investment in Japan may be more likely to be affected by such events than its investments in other geographic regions. There are special risks associated with investments in Japan, including foreign trade policy, regional economic disruption, government debt, aging and shrinking of the population, an uncertain financial sector, economic, political or social instability, low domestic consumption and certain corporate structural weaknesses.

The political history of some Asian countries has been characterized by political uncertainty, intervention by the military in civilian and economic spheres, regional conflicts and government corruption. Such developments, if they continue to occur, could reverse favorable trends toward market and economic reform, privatization, and removal of trade barriers and result in significant disruption in securities markets. The economies of many countries in the region are heavily dependent on international trade and are accordingly affected by protective trade barriers and the economic conditions of their trading partners, principally, the United States, Japan, China and the EU. The 2008–2009 worldwide economic downturn spread to the region, significantly lowering its exports and inflows of foreign investment, which are driving forces of its economic growth. In addition, the 2008–2009 worldwide economic downturn also significantly affected consumer confidence and local stock markets. The economies of many countries in the region have recently shown signs of recovery from the crisis, but there can be no assurance that such recovery will be sustained.

Unlike in the United States, the currencies of certain Asian countries are not determined by the market but are instead managed at artificial levels to the U.S. dollar. This type of system can lead to sudden and large adjustments in the currency which, in turn, can have a disruptive and negative effect on foreign investors. Certain Asian countries also may restrict the free conversion of their currency into foreign currencies, including the U.S. dollar. There is no significant foreign exchange market for certain currencies and it would, as a result, be difficult for the Funds to engage in foreign currency transactions designed to protect the value of the Funds’ interests in securities denominated in such currencies.

Asian countries have historically been prone to natural disasters, such as droughts, floods and tsunamis, and the region’s economies may be affected by such environmental events in the future. Given the particular vulnerability of the region to the effects of climate change, disruptions in international efforts to address climate-related issues may have a disproportionate impact on a Fund’s investments in the region. A Fund’s investment in or exposure to Asian countries is, therefore, subject to the risk of such events.

By investing in securities or instruments that are economically tied to the People’s Republic of China (“PRC”) excluding Hong Kong, Macau and Taiwan for the purpose of this disclosure or other developing market Asian countries, a Fund is subject to certain risks in addition to those generally applicable to investment in foreign and emerging markets. In many Asian securities markets, including but not limited to the PRC qualified foreign institutional investors program (“FII” program, including the qualified foreign institutional investor (“QFII”) program based on recent PRC regulatory developments), there is a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Many of these markets also may be affected by developments with respect to more established markets in the region. Brokers in developing market Asian countries typically are fewer in number and less well capitalized than brokers in the United States. A number of Asian companies are also highly dependent on foreign loans for their operation, which could impose strict repayment term schedules and require significant economic and financial restructuring. In addition, there is a lack of clarity in the laws and regulations in certain Asian countries compared to more developed international markets, and there could potentially be a lack of consistency in interpreting and applying the relevant regulations. These factors may severely restrict a Fund’s ability to pursue its investment objective or strategies, may result in fewer investment opportunities for a Fund and may have an adverse impact on the investment performance of a Fund.

There also exists control on foreign investment in the PRC and limitations on repatriation of invested capital. Under the FII program, which is a market access program through which PRC investments are made available, or through investments in companies listed on exchanges outside of the PRC that provide exposure to companies that are based or operated in the PRC, there are certain regulatory restrictions imposed, particularly on (without limitation) investment scope, repatriation of funds, foreign shareholding limit and account structure. Although the relevant regulations have recently been revised to relax regulatory restrictions on the onshore capital management by FIIs (including but not limited to removing the investment quota limit and simplifying routine repatriation of investment proceeds), it is a new development and is therefore subject to uncertainties as to whether and how it will be implemented in practice, especially at this early stage. On the other hand, the recently amended FII regulations are also enhancing ongoing supervision on FIIs in terms of information disclosure among other aspects. In particular, FIIs are required to procure their underlying clients (such as any Fund investing in PRC securities via FII program) to comply with PRC disclosure of interests rules and make the required disclosure on behalf of such underlying investors. As a result of PRC regulatory requirements, a Fund may be limited in its ability to invest in securities or instruments tied to the PRC and/or may be required to liquidate its holdings in securities or instruments tied to the PRC, including at an inopportune time. Under certain instances, such involuntary liquidations may result in losses for a Fund. In addition, securities exchanges in the PRC typically have the right to suspend or limit trading in any security traded on the relevant exchange. The PRC government or relevant PRC regulators may also implement policies that may adversely affect the PRC financial markets. Such suspensions, limitations or policies may have a negative impact on the performance of a Fund’s investments.

The PRC has historically been prone to natural or human disasters such as droughts, floods, pandemics, epidemics, earthquakes and tsunamis, and the region’s economy may be affected by such environmental events in the future. A Fund’s investment in the PRC is, therefore, subject to the risk of such events.

The Nuveen ESG Emerging Markets Equity ETF may invest in companies based or operated in China by investing through legal structures known as variable interest entities (“VIEs”). Certain Chinese companies have used VIEs in order to facilitate foreign investment without distributing ownership of the China-based companies primarily due to Chinese governmental restrictions on non-Chinese ownership of companies in certain industries and sectors. In such cases, the China-based operating company typically establishes an offshore company in another jurisdiction, and the offshore company enters into contractual arrangements (such as powers of attorney, equity pledge agreements, and other exclusive services or business cooperation agreements) with the China-based operating company. These contractual arrangements are intended to give the offshore company the ability to exercise power over and obtain economic rights from the China-based operating company. Shares of the offshore company, in turn, are listed and traded on exchanges outside of China and are available to non-Chinese investors such as a Fund. This arrangement allows non-Chinese investors to hold stock in the offshore company, rather than the China-based operating company, to obtain economic exposure without direct equity ownership.

VIE structures are longstanding and well known to officials and regulators in China. However, VIEs are not formally recognized under Chinese law. Intervention by the Chinese government with respect to VIEs could significantly affect the China-based operating company’s performance and the enforceability of the VIE’s contractual arrangements with the China-based company. There is a risk that China may cease to allow VIEs at any time or impose new restrictions on the structure. Investments involving a VIE may also pose additional risks because such investments are made through a company whose interests in the underlying operating company are established through contract rather than through direct equity ownership. For example, the non-Chinese offshore company’s contractual arrangement may be less effective than direct equity ownership, and the company may incur substantial costs to enforce the terms of the arrangements. Also, the terms of such arrangements may be deemed unenforceable in China, thus limiting (or eliminating) the remedies and rights available to the non-Chinese offshore company and its investors and potentially resulting in significant economic losses. Such legal uncertainty may also be exploited against the interests of the offshore company and its investors. Further, the interests of the equity owners of the operating company may conflict with the interests of the investors of the offshore company, and the fiduciary duties of the officers and directors of the operating company may differ from, or conflict with, the fiduciary duties of the officers and directors of the offshore company. Finally, there is the risk that an offshore company could face delisting or other ramifications for failure to meet the requirements of the listing exchange or United States regulators, which could adversely affect the liquidity or value of the securities and have negative implications for U.S. investors and result in significant investment losses. Any of the foregoing risks and events could negatively impact the Fund’s performance.

By investing in non-U.S. securities, each Fund will be subject to currency risk, which is the risk that an increase in the U.S. dollar relative to the non-U.S. currency will reduce returns or portfolio value. Generally, when the U.S. dollar rises in value relative to a non-U.S. currency, a Fund’s investment in securities denominated in that currency will lose value because its currency is worth fewer U.S. dollars. On the other hand, when the value of the U.S. dollar falls relative to a non-U.S. currency, a Fund’s investments denominated in that currency will tend to increase in value because that currency is worth more U.S. dollars. The exchange rates between the U.S. dollar and non-U.S. currencies depend upon such factors as supply and demand in the currency exchange markets, international balance of payments, governmental intervention, speculation and other economic and political conditions. Although the Funds value their assets daily in U.S. dollars, the Funds may not convert their holdings of non-U.S. currencies to U.S. dollars on a daily basis. The Funds may incur conversion costs when they convert their holdings to another currency. Non-U.S. exchange dealers may realize a profit on the difference between the price at which a Fund buys and sells currencies. The Funds may engage in non-U.S. currency

exchange transactions in connection with their portfolio investments. The Funds conduct their non-U.S. currency exchange transactions either on a spot (i.e., cash) basis at the spot rate prevailing in the non-U.S. currency exchange market or through forward contracts to purchase or sell non-U.S. contracts. The Funds may also be subject to currency risk through investments in ADRs and other non-U.S. securities denominated in U.S. dollars.

Sovereign Debt Obligations. The Funds may invest in sovereign debt obligations. Sovereign debt obligations involve special risks that are not present in corporate debt obligations. The foreign issuer of the sovereign debt or the foreign governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Funds may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt, and a Fund’s NAV, to the extent it invests in such securities, may be more volatile than prices of debt obligations of U.S. issuers. In the past, certain foreign countries have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debt. A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign currency reserves, the availability of sufficient foreign exchange, the relative size of the debt service burden, the sovereign debtor’s policy toward principal international lenders and local political constraints. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies and other entities to reduce principal and interest arrearages on their debt. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to service its debts.

Supranational Securities. The Funds may invest in securities issued by supranational entities. A supranational entity is formed by two or more central governments to promote economic development for the member countries. Supranational entities finance their activities by issuing bond debt and are usually considered part of the sub-sovereign debt market. Some well-known examples of supranational entities are the World Bank, International Monetary Fund, European Investment Bank, Asian Development Bank, Inter-American Development Bank and other regional multilateral development banks. These securities are subject to varying degrees of credit risk and interest rate risk.

other disruptions affecting ETFs should occur in the future, the liquidity and value of a Fund’s shares could also be substantially and adversely affected.

As in the case of other publicly traded securities, brokers’ commissions on transactions in Fund shares will be based on negotiated commission rates at customary levels.

Committee may also consider any financial risk exposures for the Nuveen Funds in conjunction with performing its functions.

For the management services and facilities furnished by the Adviser under the Management Agreement, each Fund has agreed to pay an annual management fee based on a percentage of the Fund’s average daily net assets, payable monthly, at a rate set forth in the Prospectus under “Fund Management—Management Fees.” From time to time, the Adviser may waive all or a portion of its fee. The Adviser is responsible for substantially all other expenses of the Funds, except any future distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities, fees and expenses of the independent trustees (including any trustees’ counsel fees), certain compensation expenses of the Funds’ chief compliance officer, litigation expenses, and extraordinary expenses. The following table sets forth the management fees paid by the Funds for the last three fiscal years ended October 31.

The following individuals have primary responsibility for the day-to-day implementation of the investment strategies of the Funds.

Certain portfolio managers of the Funds also manage other registered investment companies or unregistered investment pools and investment accounts, including accounts for TIAA, its affiliated investment advisers, or other client or proprietary accounts (collectively, “Accounts”), which may raise potential conflicts of interest. The Sub-Adviser and its affiliated investment advisers have put in place policies and procedures designed to mitigate any such conflicts. Additionally, TIAA or its affiliates may be involved in certain investment opportunities that have the effect of restricting or limiting Fund participation in such investment opportunities. Such conflicts and mitigating policies and procedures include the following:

under which trading for long sales of single securities over short sales of the same or closely related securities are monitored to ensure that the trades are treated fairly and equitably. Additionally, the Funds’ portfolio managers’ decisions for executing those trades are also monitored.

The investment activities of TIAA or its affiliates may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries, in certain emerging or international markets, or are subject to corporate or regulatory ownership definitions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by TIAA or its affiliates for the Funds and Accounts that may not be exceeded without the grant of a license or other regulatory or corporate consent. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of the Sub-Adviser, on behalf of the Funds or Accounts, to purchase or dispose of investments or exercise rights or undertake business transactions may be restricted by regulation or otherwise impaired. As a result, the Sub-Adviser, on behalf of the Funds or Accounts, may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when the Sub-Adviser, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

There are generally no differences between the methods used to determine compensation with respect to the Funds and the Other Accounts shown in the table below.

KPMG LLP, 200 East Randolph Street, Suite 5500, Chicago, Illinois 60601, independent registered public accounting firm, has been selected as auditors for the Funds.

The Sub-Adviser’s fixed-income traders select the broker-dealers (sell-side) with whom they do business independent of any research, strategy pieces or trade recommendations provided to the Sub-Adviser. The vast majority of institutional fixed-income trading is conducted over-the-counter rather than on exchanges, with set prices plus commissions. Fixed-income trading is based on the risk-taking practice of market making by sell-side firms, which attempt to capture the bid/ask spread on trades where capital is committed (principal model) or on a pre-negotiated spread concession for riskless principal trades (agency model).

counterparty performance. The protocol incorporates the Sub-Adviser’s knowledge of and experience with select broker-dealers with respect to providing liquidity, namely the highest bid price or lowest offer price for a particular security.

The following table sets forth the aggregate brokerage commissions paid by the Funds during the specified periods.

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “Purchase and Sale of Shares.”

The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants.

losses, if any, resulting therefrom. Any such cancelled order may be resubmitted the following Business Day using the Fund Deposit required for such Business Day.

Except as provided below, Creation Units will not be issued until the transfer of good title to a Fund of the Deposit Securities or payment of Deposit Cash, as applicable, and the payment of the Cash Component and all applicable transaction fees have been completed. In instances where a Fund accepts Deposit Securities for the purchase of a Creation Unit, the Creation Unit may be delivered in advance of receipt by a Fund of all or a portion of the applicable Deposit Securities as described below. In these circumstances, in addition to available Deposit Securities, cash must be deposited in an amount equal to the sum of (i) the Cash Component, (ii) all applicable transaction fees and (iii) an additional amount of cash equal to a percentage of the market value, as set forth in the Participant Agreement, of the undelivered Deposit Securities (the “Cash Collateral”), which shall be maintained by BBH in a general non-interest bearing collateral account. An additional amount of cash shall be required to be deposited with a Fund, pending delivery of the missing Deposit Securities, to the extent necessary to maintain the Cash Collateral with a Fund in an amount at least equal to the applicable percentage, as set forth in the Participant Agreement, of the daily marked to market value of the missing Deposit Securities. A Fund may use such Cash Collateral to buy the missing Deposit Securities at any time. Authorized Participants will be liable to a Fund for all costs, expenses, dividends, income and taxes associated with missing Deposit Securities, including the costs incurred by a Fund in connection with any such purchases. These costs will be deemed to include the amount by which the actual purchase price of the Deposit Securities exceeds the market value of such Deposit Securities on the Order Placement Date plus the brokerage and related transaction costs associated with such purchases. A Fund will return any unused portion of the Cash Collateral once all of the missing Deposit Securities have been properly received by BBH. The delivery of Creation Units so created generally will occur no later than the Settlement Date.

expect to incur brokerage and other costs in connection with assembling a sufficient number of Fund shares to constitute a redeemable Creation Unit.

In order to take delivery of Fund Securities upon redemption of Creation Units, an Authorized Participant must maintain appropriate custody arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the Fund Securities are customarily traded (or such other arrangements as allowed by the Funds or its agents), to which account such Fund Securities will be delivered. Deliveries of redemption proceeds generally will be made within two Business Days of the Order Placement Date. However, due to the schedule of holidays in certain countries, the different treatment among foreign and U.S. markets of dividend record dates and dividend ex-dates (that is the last date the holder of a security can sell the security and still receive dividends payable on the security sold), and in certain other circumstances, the delivery of in-kind redemption proceeds with respect to a Fund may take longer than two Business Days after the day on which the redemption request is received in proper form. In certain circumstances, intervening holidays in an applicable foreign market that are not holidays observed in the U.S. equity market may cause a Fund to take more than seven calendar days to deliver redemption proceeds. If neither the redeeming shareholder nor the Authorized Participant acting on behalf of such redeeming shareholder has appropriate arrangements to take delivery of the Fund securities in the applicable foreign jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of the Fund securities in such jurisdiction, the Trust may, in its discretion, exercise its option to redeem such shares in cash, and the redeeming shareholders will be required to receive its redemption proceeds in cash.

Transaction fees, as set forth in the table below, are imposed to cover transaction costs associated with the purchase or redemption of Creation Units, as applicable. Authorized Participants will be required to pay a fixed creation transaction fee and/or a fixed redemption transaction fee, as applicable, on a given day that does not vary with the number of Creation Units created or redeemed on that day. Additional variable transaction fees will be applied to certain creation and redemption transactions, including non-standard orders and whole or partial cash purchases or redemptions. The following table shows, as of the date of this SAI, the approximate value of one Creation Unit and the standard fixed and maximum additional variable transaction fees for creations and redemptions (as described above):

* As a percentage of the NAV per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

The Trustees establish the number of Trustees and may fill vacancies on the Board, except when election of Trustees by the shareholders is required under the 1940 Act. Trustees are then elected by a plurality of votes cast by shareholders at a meeting at which a quorum is present. The Declaration also provides that Trustees may be removed, with cause, by a vote of shareholders holding at least two-thirds of the voting power of the Trust, or by a vote of two-thirds of the remaining Trustees. “Cause” requires willful misconduct, dishonesty, fraud or a felony conviction. The provisions of the Declaration relating to the election and removal of Trustees may not be amended without the approval of two-thirds of the Trustees.

bringing an action against a Fund waives the right to trial by jury to the fullest extent permitted by law and any action commenced by a shareholder may be brought only in the U.S. District Court for the District of Massachusetts (Boston Division) or if any such action may not be brought in that court, then in the Business Litigation Session of Suffolk Superior Court in Massachusetts (the “Chosen Courts”), under the terms of the Declaration. Except as prohibited by law, if a shareholder commences an applicable action in a court other than a Chosen Court, the shareholder may be obligated to reimburse a Fund and any applicable Trustee or officer of a Fund made party to such proceeding for the costs and expenses (including attorneys’ fees) incurred in connection with any successful motion to dismiss, stay or transfer of the action.

Shareholder inquiries may be made by writing to the Trust, c/o the Distributor, Nuveen Securities, LLC, at 333 West Wacker Drive, Chicago, Illinois 60606.

Each Fund may elect to treat part or all of any “qualified late year loss” as if it had been incurred in the succeeding taxable year in determining the Fund’s taxable income, net capital gain, net short-term capital gain, and earnings and profits. The effect of this election is to treat any such “qualified late year loss” as if it had been incurred in the succeeding taxable year in characterizing Fund distributions for any calendar year. A “qualified late year loss” generally includes net capital loss, net long-term capital loss, or net short-term capital loss incurred after October 31 of the current taxable year, and certain other late-year losses.

ordinary income (or possibly as qualified dividend income) to the extent of the REIT’s current and accumulated earnings and profits.

If the Funds acquire any equity interest in certain foreign investment entities (i) that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties, or capital gains) or (ii) where at least 50% of the corporation’s assets (computed based on average fair market value) either produce or are held for the production of passive income (“passive foreign investment companies” or “PFICs”), the Funds will generally be subject to one of the following special tax regimes: (i) a Fund may be liable for U.S. federal income tax, and an additional interest charge, on a portion of any “excess distribution” from such foreign entity or any gain from the disposition of such shares, even if the entire distribution or gain is paid out by the Fund as a dividend to its shareholders; (ii) if a Fund were able and elected to treat a PFIC as a “qualified electing fund” or “QEF,” the Fund would be required each year to include in income, and distribute to shareholders in accordance with the distribution requirements set forth above, the Fund’s pro rata share of the ordinary earnings and net capital gains of the PFIC, whether or not such earnings or gains are distributed to the Fund; or (iii) a Fund may be entitled to mark-to-market annually shares of the PFIC, and in such event would be required to distribute to shareholders any such mark-to-market gains in accordance with the distribution requirements set forth above. The Funds intend to make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effect of these rules. The Funds may limit and/or manage their holdings in passive foreign investment companies to limit their tax liability or maximize their return from these investments.

residual interests in REMICs. The IRS has issued guidance with respect to these issues and prospective shareholders, especially charitable remainder trusts, are strongly encouraged to consult their tax advisors regarding these issues.

A beneficial holder of shares who is a non-U.S. person may be subject to state and local tax and to the U.S. federal estate tax in addition to the federal income tax consequences referred to above. If a shareholder is eligible for the benefits of a tax treaty, any income or gain effectively connected with a U.S. trade or business will generally be subject to U.S. federal income tax on a net basis only if it is also attributable to a permanent establishment maintained by the shareholder in the United States.

¹A portion of the capital loss carry-forwards are subject to an annual limitation under the Internal Revenue Code and related regulations.

Each Fund intends to pay out dividends, if any, on an annual basis. Nonetheless, the Funds might not make a dividend payment every month. Each Fund intends to distribute its net realized capital gains, if any, to investors annually. The Funds may occasionally be required to make supplemental distributions at some other time during the year. Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available. Your broker is responsible for distributing the income and capital gain distributions to you.
