Section 1 Fund Summary
Nuveen Short-Term REIT ETF
Investment Objective
Nuveen Short-Term REIT ETF (the “Fund”) seeks to track the investment results, before fees and expenses, of the Dow Jones U.S. Select Short-Term REIT Index (the “Index”).
Fees and Expenses of the Fund
The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, when buying or selling shares of the Fund, which are not reflected in this table or the example that follows:
Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)
   
Management Fees
0.35%
Distribution and/or Service (12b-1) Fees
None
Other Expenses
0.00%
Total Annual Fund Operating Expenses
0.35%
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
$36
3 Years
$113
5 Years
$197
10 Years
$443
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 11% of the average value of its portfolio.
Principal Investment Strategies
The Fund seeks to track the investment results of the Index, which is comprised of real estate investment trusts (“REITs”). REITs are publicly traded corporations or trusts that invest in residential or commercial real estate. The Index is a subset of the Dow Jones U.S. Select REIT Index (the “Base Index”), which generally includes equity REITs traded on a national securities exchange in the United States that derive at least 75% of their total revenue from the ownership and operation of real estate assets and that have a minimum total market capitalization of $200 million at the time of their inclusion. The Index selects REITs from the Base Index that are classified as concentrating their holdings in apartment buildings, hotels, self-storage facilities or manufactured home properties, as REITs investing in these sectors typically have shorter lease durations than REITs investing in other sectors. Index holdings are weighted by float-adjusted market capitalization, provided that no single REIT can comprise more than 5% of the Index as of any rebalance date. “Float-adjusted” means that the share amounts used in calculating the Index reflect only shares available to investors, with shares held by control groups, public companies and government agencies excluded. 
The Index is rebalanced quarterly after the close of the third Friday in March, June, September and December. The Index and the Base Index exclude mortgage REITs, hybrid REITs, certain other types of REITs (e.g., timber and net-lease REITs), real estate finance companies, mortgage brokers and bankers, commercial and residential real estate brokers

Section 1 Fund Summary

and estate agents, home builders, large landowners and subdividers of unimproved land, and companies that have more than 25% of their assets in direct mortgage investments. As of March 31, 2022, the Index was comprised of 37 REITs. 
The Fund attempts to replicate the Index by investing all, or substantially all, of its assets in the REITs that make up the Index, holding each REIT in approximately the same proportion as its weighting in the Index. The Fund rebalances its holdings quarterly in response to the quarterly Index rebalances. The Fund may sell REITs that are represented in the Index in anticipation of their removal from the Index, or buy REITs that are not yet represented in the index in anticipation of their addition to the Index. 
Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in REITs. The Index concentrates (i.e., holds 25% or more of its total assets) in the securities of the real estate industry, and the Fund will concentrate its investments to approximately the same extent as the Index.
Principal Risks
You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.
Concentration Risk—The Fund’s assets will generally be concentrated in the securities of issuers in the real estate sector, and, accordingly, 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 sector.
Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider or a financial intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.
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.  
Index Provider Risk—There is no assurance that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, an index provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the Fund’s costs. Unusual market conditions may cause an index provider to postpone a scheduled rebalance. Such a postponement in a time of market volatility could mean a constituent that would otherwise be removed at rebalance may remain, causing the performance and constituents of the index to vary from those expected under normal conditions. Index providers generally do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the indexes in which they license, and generally do not guarantee that an index will be calculated in accordance with its stated methodology. Losses or costs associated with any index provider errors generally will be borne by the Fund and its shareholders. 
Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. Increases in interest rates typically lower the present value of a REIT’s future earnings stream, and may make financing property purchases and improvements more costly. The risk of rising interest rates may be greater currently than would normally be the case due to the current period of historically low rates and anticipated changes in government fiscal policy initiatives. Because the market price of REITs may change based upon investors’ collective perceptions of future earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates. 
   
Section 1 Fund Summary

Investment Style Risk—The Fund invests in the securities included in, or representative of, the Index regardless of their investment merit. The Fund does not attempt to outperform the Index or take defensive positions in declining markets or in response to changing market conditions. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to the Index.  
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. 
Market Trading Risks—The Fund is an exchange-traded fund (“ETF”), and as with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of a Fund share typically will approximate its net asset value (“NAV”), there may be times when the market price and the NAV diverge more significantly, particularly in times of market volatility or steep market declines. Thus, you may pay more or less than NAV when you buy Fund shares on the secondary market, and you may receive more or less than NAV when you sell those shares. 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. 
Real Estate Investment Risk—Due to the composition of the Index, the Fund concentrates its investments in real estate companies and companies related to the real estate sector. As such, the Fund is subject to risks associated with the direct ownership of real estate, and an investment in the Fund will be closely linked to the performance of the real estate markets. These risks include, among others: declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates. The Fund's investments in the real estate market have many of the same risks as direct ownership of real estate. The real estate sector is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Real estate values have been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future. 
REITs Risk—In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. REITs may be affected by changes in real estate values, rents, property taxes, zoning laws, neighborhood values and interest rates. Further, REITs are dependent upon specialized management skills and cash flows, and may have their investments in relatively few properties, or in a small geographic area or a single property type. Failure of a company to qualify as a REIT under federal tax law, or changes to federal tax law or regulations governing REITs, may have adverse consequences to the Fund. In addition, REITs have their own expenses, and the Fund will bear a proportionate share of those expenses. Many REITs utilize leverage (and some may be highly leveraged), which increases investment risk and could potentially magnify the Fund’s losses. 
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

Section 1 Fund Summary

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. 
Smaller Company Risk—Even larger REITs may be small- to medium-sized companies in relation to the equity markets as a whole. Small-cap securities involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations, than security prices of larger, more established companies or the broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks. 
Tracking Error Risk—Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of, for example, pricing differences, transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of distributions, changes to the Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, but the Index does not. 
Fund Performance
The following bar chart and table provide some indication of the potential risks of investing in the Fund. Both the bar chart and the table assume that all distributions have been reinvested. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/etf or by calling (800) 257-8787.

During the period reflected in the bar chart above, the Fund’s highest and lowest quarterly returns were 19.26% and -29.29%, respectively, for the quarters ended December 31, 2020 and March 31, 2020.
The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and the Index. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Purchase and Sale of Fund Shares
The Fund is an ETF. Shares of the Fund are listed on a national securities exchange and can only be bought and sold in the secondary market through a broker-dealer at market prices. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (at a “premium”) or less than NAV (at a “discount”). An investor may also incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund shares (bid) and the lowest price a seller is willing to accept for Fund shares (ask) when buying and selling shares in the secondary market (the “bid/ask spread”). Recent information regarding the Fund, including its NAV, market price, premiums and discounts, and bid/ask spreads, is available on the Fund’s website at www.nuveen.com/etf.
Tax Information
The Fund’s distributions are taxable and will generally be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred account, such as an individual retirement account (“IRA”) or 401(k) plan (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund’s investment adviser or its affiliates may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Section 2 Additional Detail About the Fund’s Strategies, Holdings and Risks
This prospectus contains important information about investing in the Fund. Please read this prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.nuveen.com/etf or by calling Nuveen Investor Services at (888) 290-9881.
The Fund is designed to track an index that is not representative of the market as a whole. The Fund is designed to be used as part of a broader asset allocation strategy, and thus an investment in the Fund should not be considered a complete investment program.
The Index is a theoretical financial calculation, whereas the Fund is an actual investment portfolio. The performance of the Fund and the Index may vary for a number of reasons, including transaction costs, asset valuations, corporate actions (such as mergers and spin-offs), and differences between the Fund’s portfolio and its Index resulting from legal restrictions (such as tax diversification requirements) that apply to the Fund but not to the Index. On an annual basis, the Fund’s tracking error (i.e., the divergence of the Fund’s performance from that of the Index) is generally expected to be less than 5%.
 
  Investment Objective and Principal
Investment Strategies
The Fund’s investment objective, which is described in the “Fund Summary” section, may be changed by the Fund’s Board of Trustees (the “Board”) without shareholder approval.
The 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 Fund has adopted a policy whereby, under normal market conditions, it will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in REITs (the “Name Policy”). If the Name Policy changes, you will be notified at least 60 days in advance. The Fund may consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, the Fund will value eligible derivatives at fair value or market value and not notional value.
The Fund’s principal investment strategies are discussed in the “Fund Summary” section. These are the strategies that the 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. You should be aware that the 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.

Under normal market conditions, the Fund invests in component securities of the Index, which is comprised of REITs, in accordance with the Name Policy. The Fund may also, as a non-principal strategy, invest up to 20% of its assets in securities and other instruments that the Fund’s sub-adviser believes will help it track the Index, such as shares of other investment companies (including other ETFs), derivative instruments (including forward contracts, futures contracts, options on futures contracts, options and swaps), and cash and cash equivalents. Additional information about the Fund’s portfolio holdings can be found below.
REITs
REITs are publicly traded corporations or trusts that invest in residential or commercial real estate. REITs generally can be divided into the following three types:
· Equity REITs, which invest the majority of their assets directly in real property and derive their income primarily from rents and capital gains or real estate appreciation.
· Mortgage REITs, which invest the majority of their assets in real estate mortgage loans and derive their income primarily from interest payments.
· Hybrid REITs, which combine the characteristics of equity REITs and mortgage REITs.
The only REITs included in the Index are equity REITs. The Fund can invest in common stock, preferred securities and convertible securities issued by equity REITs.
Investment Companies and Other Pooled Investment Vehicles
As a non-principal investment strategy, the Fund may invest in securities of other open-end or closed-end investment companies, including ETFs. In addition, the Fund may invest a portion of its assets in pooled investment vehicles (other than investment companies) that invest primarily in securities of the types in which the Fund may invest directly. As a shareholder in an investment company or other pooled investment vehicle, the 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 the Fund invests in an investment company or other pooled investment vehicle. In addition, the 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 the 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. Subject to certain conditions, the Fund may invest in money market funds beyond the statutory limits described above.
Derivatives
As a non-principal investment strategy, the Fund may invest in derivatives. Generally, a derivative is a financial contract the value of which depends upon, or is derived from, the value of an underlying asset, reference rate or index. Derivatives generally take the form of contracts under which the parties agree to payments between them based upon the
   
8
Section 2 Additional Detail About the Fund’s Strategies, Holdings and Risks

performance of a wide variety of underlying references, such as stocks, bonds, loans, commodities, interest rates, currency exchange rates, and various domestic and foreign indices. Examples of derivative instruments include forward currency contracts, currency and interest rate swaps, currency options, futures contracts, options on futures contracts and swap agreements.
Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on the Fund’s performance.
Cash Equivalents and Short-Term Investments
As a non-principal investment strategy, the Fund may invest in cash and in U.S. dollar-denominated high-quality money market instruments and other short-term securities, including money market funds, in such proportions as warranted by prevailing market conditions and the Fund’s principal investment strategies. The Fund 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 the Fund from participating in a market upswing and prevent the Fund from achieving its investment objective.
Temporary Defensive Positions
In certain situations or market conditions, such as in the case of liquidity concerns and/or unusually large cash inflows or redemptions, the 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.
 
A description of the Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio holdings is available in the Fund’s statement of additional information. In addition, the identities and quantities of the securities held by the Fund are disclosed on the Fund’s website.
 
  Risks
Risk is inherent in all investing. Investing in the Fund 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 Fund. Descriptions of these risks listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Because of these risks, you should consider an investment in the Fund to be a long-term investment.
Principal Risks
Concentration risk: The Fund’s assets will generally be concentrated in the securities of issuers in the real estate sector, and, accordingly, 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 sector. Concentrated exposure to an industry or group of industries may cause the Fund to experience increased market price volatility compared to funds that invest more broadly in the overall market.
   
Section 2 Additional Detail About the Fund’s Strategies, Holdings and Risks
9

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 the Fund, the 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 the 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 the Fund invests, and thereby 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. 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. 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.
Index provider risk: There is no assurance that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, an index provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the Fund’s costs. Unusual market conditions may cause an index provider to postpone a scheduled rebalance. Such a postponement in a time of market volatility could mean a constituent that would otherwise be removed at rebalance may remain, causing the performance and constituents of the index to vary from those expected under normal conditions. Index providers generally do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the indexes in which they license, and generally do not guarantee that an index will be calculated in accordance with its stated methodology. Losses or costs associated with any index provider errors generally will be borne by the Fund and its shareholders.
Interest rate risk: Increases in interest rates typically lower the present value of a REIT’s future earnings stream, and may make financing property purchases and improvements more costly. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Because the market price of REITs may change based upon investors’
   
10
Section 2 Additional Detail About the Fund’s Strategies, Holdings and Risks

collective perceptions of future earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.
Investment style risk: The Fund invests in the securities included in, or representative of, the Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets or in response to changing market conditions. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.
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. 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 the 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 (such as Russia’s invasion of Ukraine in February of 2022), terrorism, 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 the 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 the Fund’s service providers, including the investment adviser and sub-adviser, rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the 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. 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 the Fund’s investments.
Market trading risks: 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. 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.
Only certain institutional investors are eligible to purchase and redeem shares directly from the Fund at NAV. In addition, efficient trading in the Fund’s shares on the secondary market depends on the participation of firms acting as market makers and/or

11

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, the Fund’s shares may trade at a material discount to NAV.
During periods of high market volatility, a Fund 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 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 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 (discussed in further detail below). 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).
Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the 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 Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread, which varies over time based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). The 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 Fund shares, frequent trading may detract significantly from investment results, and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.
Non-diversification risk: The 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 the Fund’s assets may be invested in the securities of a limited number of issuers, the 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 the Fund to a greater extent than a more broadly diversified fund and the Fund’s share price may fluctuate more than that of a comparable diversified fund.
Real estate investment risk: Fund investments in real estate securities are closely linked to the performance of the real estate markets and subject to the risks associated with the direct ownership of real estate. Real estate companies are subject to substantial fluctuations and declines on a local, regional and national basis in the past that may continue to occur in the future. Real property values and incomes from real property may decline due to general and local economic conditions, overbuilding and increased competition, delays in completion of construction, increases in property taxes and

operating expenses, changes in zoning laws, low demand, casualty or condemnation losses, regulatory limitations on rents, changes in neighborhoods and in demographics, increases in market interest rates, liabilities or losses due to environmental problems, defaults by mortgagors or other borrowers, loss of rental income, possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets, or other factors. The Fund’s investments in the real estate market have many of the same risks as direct ownership of real estate. Factors such as these may adversely affect companies which own and operate real estate directly, companies which lend to them, and companies which service the real estate industry. The Fund’s income could decline when the Fund experiences reduced distributions from real estate companies it holds. Additionally, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which may increase investment risk and are highly dependent on cash flows. To the extent the Fund’s underlying assets are concentrated geographically, by property type or in certain other respects, the Fund may be subject to certain of the foregoing risks to a greater extent.
Negative economic impacts caused by COVID-19 have resulted in a number of businesses and individuals being unable to pay all or a portion of their rents, which has created cash flow difficulties for many landlords. Furthermore, demand for some categories of leased commercial and retail space has weakened. Real estate companies, including REITs, provide space to many industries that have been directly impacted by the spread of COVID-19 and may be negatively impacted by these conditions.
REITs risk: In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. Equity REITs will be affected by changes in the values of and incomes from the properties they own, while mortgage REITs may be affected by the credit quality of the mortgage loans they hold. REITs are subject to other risks as well, including the fact that REITs are dependent on specialized management skills which may affect their ability to generate cash flow for operating purposes and to make distributions to shareholders or unitholders. REITs may have limited diversification and are subject to the risks associated with obtaining financing for real property.
A U.S. domestic REIT can pass its income through to shareholders or unitholders without any tax at the entity level if it complies with various requirements under the Internal Revenue Code. There is the risk that a REIT held by the Fund will fail to qualify for this tax-free pass-through treatment of its income. Similarly, REITs formed under the laws of non-U.S. countries may fail to qualify for corporate tax benefits made available by the governments of such countries. Failure by a U.S. or non-U.S. REIT to qualify for favorable tax treatment could adversely affect the value of such REIT.
By investing in REITs indirectly through the Fund, in addition to bearing a proportionate share of the expenses of the Fund, shareholders of the Fund will also indirectly bear similar expenses of the REITs in which the Fund invests.
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.
   
Section 2 Additional Detail About the Fund’s Strategies, Holdings and Risks
13

Smaller company risk: Even larger REITs may be small- to medium-sized companies in relation to the equity markets as a whole. Stocks of small-cap companies involve substantial risk. These companies may lack the management expertise, financial resources, product diversification, and competitive strengths of larger companies. Prices of small-cap stocks may be subject to more abrupt or erratic movements than stock prices of larger, more established companies or the 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. In some cases, there could be difficulties in selling the stocks of small-cap companies at the desired time and price. Stocks at the bottom end of the capitalization range of small-cap companies sometimes are referred to as “micro-cap” stocks. These stocks may be subject to extreme price volatility, as well as limited liquidity and limited research. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.
Tracking error risk: Tracking error is the divergence of the Fund’s performance from that of its Index. Tracking error may occur because of, for example, pricing differences, transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of distributions, changes to its Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, but the Index does not.
Non-Principal Risks
Derivatives risk: The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Derivatives can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by the Fund will not correlate with the asset, index or rate underlying the derivative contract.
The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the contract. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. These risks are heightened when the management team uses derivatives to enhance the Fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the Fund.
In addition, when the Fund engages in certain derivative transactions, it is effectively leveraging its investments, which could result in exaggerated changes in the NAV of the Fund’s shares and can result in losses that exceed the amount originally invested. The success of the Fund’s derivatives strategies will depend on the sub-adviser’s ability to assess and predict the impact of market or economic developments on the underlying asset, index or rate and the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions.
The Fund may also enter into over-the-counter (“OTC”) transactions in derivatives. Transactions in the OTC markets generally are conducted on a principal-to-principal basis. The terms and conditions of these instruments generally are not standardized and tend to be more specialized or complex, and the instruments may be harder to value. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges. In addition, certain derivative instruments and markets may not be liquid, which means the Fund may not be able to close out a derivatives transaction in a cost-efficient manner.
   
14
Section 2 Additional Detail About the Fund’s Strategies, Holdings and Risks

Short positions in derivatives may involve greater risks than long positions, as the risk of loss on short positions is theoretically unlimited (unlike a long position, in which the risk of loss may be limited to the notional amount of the instrument).
Swap agreements may involve fees, commissions or other costs that may reduce the Fund’s gains from a swap agreement or may cause the Fund to lose money.
Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for the Fund to close out a position when desired.
Options contracts may expire unexercised, which may cause the Fund to realize a capital loss equal to the premium paid on a purchased option or a capital gain equal to the premium received on a written option.
Global economic risk: National and regional economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and securities prices around the world, which could negatively impact the value of the 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 the 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 the Fund’s service providers, including the investment adviser and sub-adviser, rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the 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 the Fund’s investments.
Other investment companies risk: When the 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, the Fund is exposed to the risks to which the other investment companies may be subject. For 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 Fund
 
The 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 Fund through a broker on a national securities exchange, where the Fund’s shares are listed and trade throughout the day at market prices like shares of other publicly traded securities. The Fund does not impose any minimum investment for shares of the Fund purchased on an exchange or otherwise in the secondary market. The Fund’s shares trade under the trading symbol listed on the cover of this prospectus.
Purchasing or selling shares of the Fund on an exchange or other secondary market typically involves two types of costs. When purchasing or selling shares of the 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 the Fund. The spread will vary over time based on the Fund’s trading volume and market liquidity.
The Fund’s primary listing exchange is the Cboe BZX Exchange, Inc. (the “Listing Exchange”). The Listing Exchange is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth Holiday, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
Book Entry
Shares of the Fund 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 Fund and is recognized as the owner of all shares for all purposes.
Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.
Share Trading Prices
The trading prices of the 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 the Fund’s shares, which may be more or less than the NAV of such shares.

Section 4 Investing in the Fund

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 Fund. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Rule 12d1-4 under the 1940 Act, including that such investment companies enter into an agreement with the Fund.
 
Only certain institutional investors (typically market makers or other broker-dealers) who have entered into agreements with the Nuveen Securities, LLC, the Fund’s distributor (the “Distributor”), (“Authorized Participants”) may purchase and redeem shares directly from the Fund 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 the 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 Fund generally issues and redeems 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, the Fund publishes that day’s Basket through NSCC or another method of public dissemination.
Orders from Authorized Participants to create or redeem Creation Units may only be placed on a Business Day and are subject to approval by the Distributor. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received and deemed acceptable by the Distributor.
Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s statement of additional information.
 
  Distributor
Nuveen Securities, LLC, the Fund’s distributor, distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 333 West Wacker Drive, Chicago, Illinois 60606.
   
Section 4 Investing in the Fund

Distribution and Service Plan
The 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 Fund; 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 the 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 Fund 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 Fund. 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 Fund or other Nuveen ETFs over another investment. More information regarding these payments is contained in the Fund’s statement of additional information.

Section 4 Investing in the Fund

 
The Fund does not impose any restrictions on the frequency of purchases and redemptions (“frequent trading”); however, the Fund reserves 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 Fund and its shareholders. The Board considered that the 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 Fund’s shares occurs on the secondary market. Because secondary market trades do not involve the Fund 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 the Fund’s trading costs and the realization of capital gains. With respect to purchases and redemptions by Authorized Participants directly from the Fund 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 the 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 the Fund’s shares trade at or close to NAV. In addition, the Board recognized that the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades.

Section 5 General Information
 
As a Fund shareholder, you are entitled to your share of the Fund’s income and net realized gains on its investments. The Fund pays out substantially all of the distributions it receives from its investments in REITs, less expenses. Distributions from REITs may include income, return of capital and capital gains. The Fund declares and pays distributions quarterly.
The Fund may also realize capital gains on the sale of its REIT investments. The 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. The 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 the Fund’s net long-term capital gains over its net short-term capital losses) are distributed to shareholders once a year at year end.
The 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 Fund. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the 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 Fund purchased in the secondary market.
 
  Taxes
As with any investment, you should consider how your investment in shares of the Fund 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 Fund, or the tax consequences of an investment in the Fund. There is no guarantee that shares of the Fund 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 Fund. 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 Fund makes distributions, you sell Fund shares, or (for Authorized Participants only) you purchase or redeem Creation Units.
Taxes and Tax Reporting
The 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
   
22
Section 5 General Information

not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, the 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.
The Fund intends to make distributions that may be taxed as ordinary income or capital gains. Distributions of the 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.
Since the Fund’s income is derived primarily from investment in REITs, it is not expected that the Fund will distribute “qualified dividend income” or income that would qualify for the dividends-received deduction for corporate shareholders.
The Fund’s investments in REITs may at times result in the Fund’s receipt of cash in excess of the REIT’s earnings (a “return of capital”); if the Fund distributes these amounts, these distributions could constitute a return of capital to the Fund’s shareholders for federal income tax purposes.
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 the Fund before your investment (and thus were included in the price you paid for your shares).
REITs in which the Fund invests often do not provide complete and final tax information to the Fund until after the time that the Fund issues a tax reporting statement. As a result, the Fund may at times find it necessary to reclassify the amount and character of its distributions after it issues a tax reporting statement. If this were to occur, the financial intermediary with whom you hold your shares will send you a corrected, final Form 1099-DIV to reflect the reclassified information.
Early in each year, you will receive a statement from the firm through which you hold your Fund shares detailing the amount and nature of all distributions that you were paid during the prior year. The tax status of your distributions is the same whether you reinvest them or elect to receive them in cash. 
Dividends and distributions from the Fund and capital gain on the sale of Fund shares are generally taken into account in determining a shareholder’s “net investment income”

When seeking to satisfy redemption requests in whole or in part on a cash basis, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. This may cause the 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, the Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process were used.
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 the 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. The Fund may, under certain circumstances, report all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met. Different tax consequences may result if you are a foreign shareholder engaged in a trade or business within the United States or if you are a foreign shareholder entitled to claim the benefits of a tax treaty.
Please note that if you do not furnish the Fund with your correct Social Security number or employer identification number, you fail to provide certain certifications to the Fund, you fail to certify whether you are a U.S. citizen or a U.S. resident alien, or the Internal Revenue Service notifies the Fund to withhold, federal law requires the Fund to withhold federal income tax from your distributions and redemption proceeds at the applicable withholding rate.
Qualified Business Income
A large portion of the Fund’s portfolio holdings consist of REITs. For tax years beginning after December 31, 2017, the Tax Cuts and Jobs Act generally would allow a non-corporate taxpayer a deduction equal to the investor’s combined qualified business income, which would include 20% of the investor’s qualified REIT dividends. Treasury has issued regulations that allow regulated investment companies (“RICs”) such as the Fund to report a portion of their distributions that relate to dividends received from REITs as qualified REIT dividends eligible for the 20% deduction. The total amount of Fund distributions that qualify for this deduction is disclosed to investors on their Forms 1099-DIV, which are made available in February after the close of a calendar year.
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.

Section 5 General Information

If you do not make an election, your financial intermediary will choose its own default cost basis method.
Taxes on Creation and Redemption of Creation Units
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.
The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. 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 Fund under all applicable tax laws.
 
The 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. The 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. The 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. 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
   
Section 5 General Information
25

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.
If a price cannot be obtained from a pricing service or other pre-approved source, or if, in the judgment of the Adviser, a price is unreliable, a portfolio instrument will be valued at its fair value as determined in good faith by the Board or its appointee. The Adviser may determine that a price is 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 adopted valuation procedures for the Fund and has appointed the Adviser’s Valuation Committee with the day-to-day responsibility for fair value determinations. All fair value determinations made by the Valuation Committee are subject to review and ratification 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.
 
Information showing the number of days the market price of the 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 Fund’s website at www.nuveen.com/etf.
