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.
 
The Securities and Exchange Commission (“SEC”) has not approved or disapproved these securities or passed upon the adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Nuveen Dividend Growth ETF
Investment Objective
The investment objective of the Fund is to seek an attractive total return comprised of income from dividends and long-term capital appreciation.
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
0.64%
Distribution and/or Service (12b-1) Fees
None
Other Expenses
0.00%
Total Annual Fund Operating Expenses
0.64%
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
$65
3 Years
$205
5 Years
$357
10 Years
$798
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 12% of the average value of its portfolio.
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.
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

Section 1 Fund Summaries

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

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.  
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. 
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  
   
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. 
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.  
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.

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. 
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
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.

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.
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 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:

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 39% of the average value of its portfolio.
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.

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.

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.

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. 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.  
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. 
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.

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 RiskThe 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. 
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. 
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.  
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. 
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. 
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. 
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.

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. 
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. 
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. 
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.

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.
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.

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:

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:

$471
10 Years
$1,049
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 64% of the average value of its portfolio.
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

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. 
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.
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. 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.  
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. 
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. 
Emerging Markets RiskThe 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. 
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. 
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.  
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.

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. 
Small-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.

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.
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.

Investment Objective
The investment objective of the Fund is to provide long-term capital appreciation.
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:

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:

5 Years
$357
10 Years
$798
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 58% of the average value of its portfolio.
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. 
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  
   
22
Section 1 Fund Summaries

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
23

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.  
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. 
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. 
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  
   
24
Section 1 Fund Summaries

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. 
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.  
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.  
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. 
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. 
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. 
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  
   
Section 1 Fund Summaries
25

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. 
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. 
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.

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.

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 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
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.
   
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.
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.
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.
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 (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.
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 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
   
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.
· 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.
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.
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

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.
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.
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 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
   
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.
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- 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.

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.
Non-Principal Risks
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).

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.
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

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.
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
   
50
Section 4 Investing in the Funds

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. It is possible that Fund shares will trade with a larger premium/discount because of its non-transparent structure, and this risk may increase during times of market stress or volatility.
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”) (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”).
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 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
   
Section 4 Investing in the Funds
51

basis. 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.
 
  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.

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 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 quarterly for the Nuveen Dividend Growth ETF and annually for all other ETFs in this prospectus.
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).
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
   
Section 5 General Information
55

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.
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. 
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.
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.

Section 5 General Information

Taxes on Creation and Redemption of Creation Units
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 amount of 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 amount of cash paid for such Creation Units. An Authorized Participant 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 the securities plus the amount of any cash received for such Creation Units. The Internal Revenue Service, 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.
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.
Foreign Investments by the Funds
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.
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.

  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.

  Listing Exchange
Shares of the Funds are not sponsored, endorsed or promoted by the Listing Exchange. The Listing Exchange makes no representation or warranty, express or implied, to the owners of shares of the Funds or any member of the public regarding the ability of a Fund to achieve its investment objective. The Listing Exchange is not responsible for, nor has it participated in, the determination of the timing of, prices of or quantities of shares of the Funds to be issued, nor in the determination or calculation of the equation by which the shares are redeemable. The Listing Exchange has no obligation or liability to owners of shares of the Funds in connection with the administration, marketing or trading of shares of the Funds. Without limiting any of the foregoing, in no event shall the Listing Exchange have any liability for any direct, indirect, special, punitive, consequential or any other damages (including lost profits) even if notified of the possibility of such damages.
 
  Proxy Portfolio and Proxy Overlap
Information regarding the contents of the Proxy Portfolio, and the percentage weight overlap between the holdings of the Proxy Portfolio and a Fund’s Actual Portfolio holdings that formed the basis for its calculation of NAV at the end of the prior Business Day (the “Proxy Overlap”), can be found 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.
