Chair’s Letter to Shareholders

Dear Shareholders,

More than a year has passed since the World Health Organization declared COVID-19 a global pandemic in March 2020, resulting in a year marked by a global economic downturn, financial market turbulence and some immeasurable losses of life. Although the health crisis persists, with the widespread distribution of vaccines in the U.S. and extraordinary economic interventions by governments and central banks around the world, we collectively look forward to what our “new normal” might be.

Rebounding global economic activity has driven both gross domestic product growth and inflation higher, especially in the U.S. Vaccinations have enabled a further reopening of economies while governments and central banks have taken extraordinary measures to support the recoveries. Since the crisis began, the U.S. government has enacted six relief measures totaling $5.3 trillion to support individuals and families, small and large businesses, state and local governments, education, public health and vaccinations. Currently, Congress is working on an infrastructure spending plan, although its final shape and whether it passes remains to be seen. The U.S. Federal Reserve (Fed) and other central banks around the world have acknowledged the economic progress to date but remain committed to sustaining the recovery by maintaining accommodative monetary conditions. However, as economies have reopened, the surge in consumer demand has outpaced supply chain capacity, resulting in a jump in inflation indicators in recent months. Whether inflation persists is a subject of debate by economists and some market observers, while the Fed and other central banks believe it to be more transitory. Additionally, the recent impact of the COVID-19 delta variant is likely to be factored into central bank forecasts, which could complicate the timing of monetary policy changes.

While the markets’ longer-term outlook has brightened, we expect intermittent bouts of volatility to continue. There are some signs that the first economies to recover – including China, the U.S. and Europe not far behind – have reached their growth peaks and are moving toward stabilization, while the delta variant is adding caution to the growth outlook. Markets are closely monitoring central bank signals, particularly if inflation remains elevated, as a sooner-than-expected shift to monetary tightening could slow the economic recovery. Additionally, as more virulent strains of COVID-19 such as the delta variant have spread, both case counts and hospitalizations are rising again, and vaccination rollouts have been uneven around the country and around the world. The recovery hinges on controlling the virus, and estimates vary considerably on when economic activity might be fully restored and what level of public inoculation would be sufficient to contain the spread of the virus, particularly in light of new variants. On the political front, the Biden administration’s full policy agenda and the potential for Congressional gridlock remain to be seen, either of which could cause investment outlooks to shift. Short-term market fluctuations can provide your Fund opportunities to invest in new ideas as well as upgrade existing positioning while providing long-term value for shareholders. For more than 120 years, the careful consideration of risk and reward has guided Nuveen’s focus on delivering long-term results to our shareholders.

If you have concerns about what’s coming next, it may be an opportune time to assess your portfolio. We encourage you to review your time horizon, risk tolerance and investment goals with your financial professional.

On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

These Funds feature portfolio management by Teachers Advisors, LLC, an affiliate of Nuveen Fund Advisors, LLC. Portfolio managers include Lijun (Kevin) Chen, CFA, and Yong (Mark) Zheng, CFA. Kevin has managed the Funds since their inceptions and Mark was added as a portfolio manager in June 2018.

Here the portfolio management team discusses U.S. economic and market conditions, key investment strategies and the performance of the Funds for the twelve-month reporting period ended July 31, 2021. For more information on each Fund’s investment objectives and policies, please refer to each Fund’s prospectus.

What factors affected the U.S. economy and the bond market during the twelve-month annual reporting period ended July 31, 2021?

Supported by massive fiscal and monetary stimulus and economic reopening, the U.S. economy rebounded more quickly than expected from the deep downturn caused by the COVID-19 crisis and containment measures. The federal government’s relief measures have totaled approximately $5.3 trillion across six aid packages that have allocated direct payments to individuals and families, expanded unemployment insurance, provided loans to large and small businesses, funded hospitals and health agencies, and supported state and local governments, education and public health/vaccination. (Additionally, in August 2021, after the close of this reporting period, the Senate approved a $1 trillion infrastructure and jobs plan, which moves to the House for consideration.) The U.S. Federal Reserve (Fed) has maintained short-term interest rates near zero and enacted credit facilities to help keep the financial system stable, lowering borrowing costs for businesses and individuals. Gross domestic product (GDP) expanded at an annualized rate of 6.3% in the first quarter and 6.5% in the second quarter, according to the “advance” estimate released by the Bureau of Economic Analysis, after shrinking 3.5% (annualized) in 2020 compared to 2019’s annual level.

By the start of this reporting period, markets had largely stabilized from the initial health crisis shock. In March 2020, equity and commodity markets sold off and safe-haven assets rallied as countries initiated quarantines, restricted travel and shuttered factories and businesses, while an ill-timed oil price war between the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC member Russia amplified price volatility. In late 2020, the announcement of high efficacy rates in several COVID-19 vaccine trials, fol-

For NUAG and NUSA, if all three of Moody’s, S&P, and Fitch provide a rating for a security, an average of the ratings is used; if two of the three agencies rate a security, an average of the two is used; and if only one rating agency rates a security, that rating is used. For NUHY and NUBD, if all three of Moody’s, S&P, and Fitch provide a rating for a security, the middle rating is used; if two of the three agencies rate a security, the lower rating is used; and if only one rating agency rates a security, that rating is used. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. Credit ratings are subject to change. U.S. Treasury, U.S. Agency, and U.S. Agency mortgage-backed securities are included in the U.S. Treasury/Agency category.

Portfolio Managers’ Comments (continued)

lowed by regulatory authorizations and public vaccination drives across Western countries, improved the outlook for 2021, which contributed to risk-on sentiment in the markets. Increasing vaccination rates and certain surprisingly strong economic readings in the first few months of 2021 led to rising inflation concerns. However, recent Fed commentary pointed to Fed Fund rate hikes by 2023, calming market fears of inaction.

The improving economy and rising inflation pressures steepened the yield curve and drove interest rates higher. Rates had peaked in the first quarter of 2021 then partially retreated by the end of the reporting period. As of July 31, 2021, yields on U.S. Treasuries with 1-year maturities fell to 0.07% (from 0.11% as of July 31, 2020), 5-year Treasury yields rose to 0.69% (from 0.22%), 10-year yields rose to 1.23% (from 0.54%) and 30-year yields rose to 1.90% (from 1.20%). While government bond performance was negative for the reporting period, spread sectors (non-governmental fixed income investments with higher yields at greater risk than governmental investments) generally outperformed as credit spreads continued to narrow. Demand for incremental yield remained strong, with risk appetite supported by economic and vaccine optimism, accommodative monetary policy signals from the Fed and anticipated fiscal stimulus from the Biden administration.

Nuveen Enhanced Yield U.S. Aggregate Bond ETF (NUAG)

What key strategies were used to manage the Fund during the six-month reporting period and how did these strategies influence performance?

The Fund employs a passive management (or “indexing”) approach, seeking to track the investment results, before fees and expenses, of the ICE BofA Enhanced Yield U.S. Broad Bond Index (the “NUAG Enhanced Index”). The NUAG Enhanced Index is designed to broadly capture the U.S. investment grade fixed income market and uses a rules-based weighting methodology that seeks to enhance yield while maintaining comparable risk. The NUAG Enhanced Index is primarily comprised of U.S. government securities, debt securities issued by U.S. corporations, residential and commercial mortgage-backed securities, asset-backed securities and U.S. dollar-denominated debt securities issued by non-U.S. corporations that are publicly offered for sale in the U.S. The NUAG Enhanced Index selects from the securities included in the ICE BofA U.S. Broad Market Index (the “Base Index”), which consists of U.S. dollar-denominated, investment grade taxable debt securities with fixed rate coupons that have at least one year to final maturity.

The Fund generally invests in a sample of the securities in the NUAG Enhanced Index whose risk, return and other characteristics resemble the risk, return and other characteristics of the NUAG Enhanced Index. Under normal market conditions, the Fund invests at least 80% of its assets, exclusive of collateral held from securities lending, in component securities of the NUAG Enhanced Index. To the extent the NUAG Enhanced Index concentrates (i.e., holds 25% or more of its total assets) in the securities of companies in a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the NUAG Enhanced Index. The Fund rebalances its holdings monthly in response to the monthly NUAG Enhanced Index rebalances. During the reporting period, the Fund has remained fully invested within its allocation targets to track the NUAG Enhanced Index.

How did the Fund perform during the twelve-month reporting period ended July 31, 2021?

The Fund’s total returns at net asset value (NAV) are compared with the performance of the NUAG Enhanced Index, which the Fund is designed to track. The Fund’s total return underperformed the NUAG Enhanced Index during the reporting period. The relative underperformance is mainly attributable to the representative sampling process, primarily within the securitized sector, that utilizes a subset of Index securities in an effort to provide exposure similar to that of the NUAG Enhanced Index, which leads the Fund to be overweight and underweight (and, in some cases, not invested at all in) certain securities as compared to the Index, transaction costs related to the Fund’s acquisition of portfolio securities, and the fees and expenses incurred by the Fund that are not incurred by the NUAG Enhanced Index. The NUAG Enhanced Index is unmanaged and therefore its returns do not reflect any fees or expenses, which would detract from its performance. You cannot invest directly in an index.

What key strategies were used to manage the Fund during the twelve-month reporting period and how did these strategies influence performance?

The Fund employs a passive management (or “indexing”) approach, seeking to track the investment results, before fees and expenses, of the ICE BofA Enhanced Yield 1-5 Year U.S. Broad Bond Index (the “NUSA Enhanced Index”). The NUSA Enhanced Index is designed to broadly capture the 1-5 year U.S. investment grade fixed income market and uses a rules-based weighting methodology that seeks to enhance yield while maintaining comparable risk. The NUSA Enhanced Index is primarily comprised of U.S. government securities, debt securities issued by U.S. corporations, residential and commercial mortgage-backed securities, asset-backed securities and U.S. dollar-denominated debt securities issued by non-U.S. corporations that are publicly offered for sale in the U.S. The NUSA Enhanced Index selects from the securities included in the ICE BofA 1-5 Year U.S. Broad Market Index (the “Base Index”), which consists of U.S. dollar-denominated, investment grade taxable debt securities with a remaining term to final maturity, or an average life, of less than five years.

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

The Fund’s total returns at net asset value (NAV) are compared with the performance of the NUSA Enhanced Index, which the Fund is designed to track. For the reporting period, the Fund’s total return underperformed that of the NUSA Enhanced Index. The relative underperformance is mainly attributable to the representative sampling process, primarily within the securitized sectors, that utilizes a sub-set of Index securities in an effort to provide exposure similar to that of the NUSA Enhanced Index, which leads the Fund to be overweight and underweight (and, in some cases, not invested at all in) certain securities as compared to the Index, transaction costs related to the Fund’s acquisition of portfolio securities, and the fees and expenses incurred by the Fund that are not incurred by the NUSA Enhanced Index.

Nuveen ESG High Yield Corporate Bond ETF (NUHY)

What key strategies were used to manage the Fund during the twelve-month reporting period and how did these strategies influence performance?

The Fund employs a passive management (or “indexing”) approach, investing in a diversified portfolio of U.S. dollar-denominated, high yield, fixed-rate corporate bonds that satisfy certain environmental, social and governance (“ESG”) criteria. The Fund seeks to track the investment results, before fees and expenses, of the Bloomberg MSCI U.S. High Yield Very Liquid ESG Select Index (“the NUHY Select Index”). The NUHY Select Index is composed of U.S. dollar-denominated below investment grade corporate bonds with above average liquidity that satisfy certain ESG and low-carbon criteria. Below investment grade bonds are commonly referred to as “high yield” or “junk” bonds. The NUHY Select Index selects from the securities included in the Bloomberg U.S. High Yield Very Liquid Index (the “Base Index”), which is designed to broadly capture the U.S. dollar-denominated, high yield, fixed-rate corporate bond market.

The Fund generally invests in a sample of the securities in the NUHY Select Index whose risk, return and other characteristics resemble the risk, return and other characteristics of the NUHY Select 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 component securities of the NUHY Select Index.

Risk Considerations and Dividend Information

Nuveen Enhanced Yield U.S. Aggregate Bond ETF

Investing involves risk; principal loss is possible. This is no guarantee the Fund's investment objective will be achieved. An exchange-traded fund seeks to generally track the investment results of an index; however the Fund may underperform, outperform or be more volatile than the referenced index. Interest rate risk occurs when interest rates rise causing bond prices to fall. Credit risk arises from an issuer's ability to make interest and principal payments when due, as well as the prices of bonds declining when an issuer's credit quality is expected to deteriorate. These and other risk considerations are described in detail in the Fund's prospectus.

Nuveen Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF

Investing involves risk; principal loss is possible. There is no guarantee the Fund's investment objectives will be achieved. This ETF seeks to generally track the investment results of an index; however the Fund may underperform, outperform or be more volatile than the referenced index. Interest rate risk is the risk that the value of the Fund's portfolio will decline because of rising interest rates. Credit Risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer's ability or willingness to make such payments. These and other risk considerations are described in detail in the Fund's prospectus.

Nuveen ESG High Yield Corporate Bond ETF

Investing involves risk; principal loss is possible. There is no guarantee the Fund’s investment objectives will be achieved. This ETF seeks to generally track the investment results of an index; however the Fund may underperform, outperform or be more volatile than the referenced index. In addition, because the Index selects securities for inclusion based on environmental, social, and governance (ESG) criteria, the Fund may forgo some market opportunities available to funds that don’t use these criteria. Investments in below investment grade or high yield securities are subject to liquidity risk and heightened credit risk. Credit risk arises from an issuer’s ability to make interest and principal payments when due, as well as the prices of bonds declining when an issuer’s credit quality is expected to deteriorate. The Fund is subject to interest rate risk; as interest rates rise, bond prices fall. These and other risk considerations, such as call, concentration and income risks, are described in detail in the Fund’s prospectus.

Dividend Information

Each Fund seeks to pay monthly dividends out of its net investment income. Monthly distributions are not expected to be a level amount from period-to-period. Each Fund will, over time, pay all its net investment income as dividends to shareholders.

All monthly dividends paid by each Fund during the current reporting period were paid from net investment income. If a portion of the Fund's monthly distributions is sourced or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders will be notified of those sources. For financial reporting purposes, the per share amounts of each Fund's dividends for the reporting period are presented in this report's Financial Highlights. For income tax purposes, distribution information for NUAG, NUSA, NUHY and NUDB as of their most recent tax year end is presented in Note 6 - Income Tax Information within the Notes to Financial Statements of this report.

Yields as of July 31, 2021

Dividend Rate is the average dividend per share for the current reporting period divided by the offering price per share at period end.

The SEC 30-Day Yield is a standardized measure of a fund’s yield that accounts for the future amortization of premiums or discounts of bonds held in the fund’s portfolio. The SEC 30-Day Yield is computed under an SEC standardized formula and is based on the maximum offer price per share. Dividend Rate may differ from the SEC 30-Day Yield because the fund may be paying out more or less than it is earning and it may not include the effect of amortization of bond premium.

Holding Summaries as of July 31, 2021

This data relates to the securities held in each Fund's portfolio of investments as of the end of this reporting period. It should not be construed as a measure of performance for the Fund itself. Holdings are subject to change.

Each Fund uses credit quality ratings for its portfolio securities provided by Moody's, S&P and Fitch. For NUAG and NUSA, if all three of Moody's S&P, and Fitch provide a rating for a security, an average of the ratings is used; if two of the three agencies rate a security, an average of the two is used; and if only one rating agency rates a security, that rating is used. For NUHY and NUBD, if all three of Moody's S&P, and Fitch provide a rating for a security, the middle rating is used; if two of the three agencies rate a security, the lower rating is used; and if only one rating agency rates a security, that rating is used. AAA, AA, A and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. Credit ratings are subject to change. U.S. Treasury, U.S. Agency, and U.S. Agency mortgage-backed securities are included in the U.S. Treasury/Agency category.

Expense Examples

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares, and (2) ongoing costs, including management fees and other applicable Fund expenses. The Examples below are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

The Examples below are based on an investment of $1,000 invested at the beginning of the period and held through the period ended July 31, 2021.

The beginning of the period is February 1, 2021.

The information under “Actual Performance,” together with the amount you invested, allows you to estimate actual expenses incurred over the reporting period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.60) and multiply the result by the cost shown for your Fund in the row entitled “Expenses Incurred During Period” to estimate the expenses incurred on your account during this period.

The information under “Hypothetical Performance” provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expense you incurred for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of July 31, 2021, by correspondence with custodians and brokers or other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

	For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.
(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(2)	The Fund uses credit quality ratings for its portfolio securities provided by Moody's, S&P and Fitch. If all three of Moody's, S&P, and Fitch provide a rating for a security, an average of the ratings is used; if two of the three agencies rate a security, an average of the two is used; and if only one rating agency rates a security, that rating is used. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. Credit ratings are subject to change. Holdings designated N/R are not rated by Moody's, S&P or Fitch. Ratings are not covered by the report of independent registered public accounting firm.
(3)	Investment, or a portion of investment, is out on loan for securities lending. The total value of the securities out on loan as of the end of the reporting period was $1,571,525.
(4)	Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(5)	The Fund may loan securities representing up to one third of the market value of its total assets (which includes collateral for securities on loan) to broker dealers, banks, and other institutions. The collateral maintained by the Fund shall have a market value, at the inception of each loan, equal to not less than 100% of the market value of the loaned securities. The cash collateral received by the Fund is invested in this money market fund.
(6)	The rate shown is the one-day yield as of the end of the reporting period.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
DD1	Portion of investment purchased on a delayed delivery basis.
WI/DD	Purchased on a when-issued or delayed delivery basis.

	For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.
(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(2)	The Fund uses credit quality ratings for its portfolio securities provided by Moody's, S&P and Fitch. If all three of Moody's, S&P, and Fitch provide a rating for a security, an average of the ratings is used; if two of the three agencies rate a security, an average of the two is used; and if only one rating agency rates a security, that rating is used. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. Credit ratings are subject to change. Holdings designated N/R are not rated by Moody's, S&P or Fitch. Ratings are not covered by the report of independent registered public accounting firm.
(3)	Investment, or a portion of investment, is out on loan for securities lending. The total value of the securities out on loan as of the end of the reporting period was $271,949.
(4)	The Fund may loan securities representing up to one third of the market value of its total assets (which includes collateral for securities on loan) to broker dealers, banks, and other institutions. The collateral maintained by the Fund shall have a market value, at the inception of each loan, equal to not less than 100% of the market value of the loaned securities. The cash collateral received by the Fund is invested in this money market fund.
(5)	The rate shown is the one-day yield as of the end of the reporting period.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
WI/DD	Purchased on a when-issued or delayed delivery basis.

	For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.
(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(2)	The Fund uses credit quality ratings for its portfolio securities provided by Moody's, S&P and Fitch. If all three of Moody's, S&P, and Fitch provide a rating for a security, the middle is used; if two of the three agencies rate a security, the lower rating is used; and if only one rating agency rates a security, that rating is used. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. Credit ratings are subject to change. Holdings designated N/R are not rated by Moody's, S&P or Fitch. Ratings are not covered by the report of independent registered public accounting firm.
(3)	Investment, or a portion of investment, is out on loan for securities lending. The total value of the securities out on loan as of the end of the reporting period was $1,796,839.
(4)	Perpetual security. Maturity date is not applicable.
(5)	The Fund may loan securities representing up to one third of the market value of its total assets (which includes collateral for securities on loan) to broker dealers, banks, and other institutions. The collateral maintained by the Fund shall have a market value, at the inception of each loan, equal to not less than 100% of the market value of the loaned securities. The cash collateral received by the Fund is invested in this money market fund.
(6)	The rate shown is the one-day yield as of the end of the reporting period.

Portfolio of Investments July 31, 2021

	For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.
(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(2)	The Fund uses credit quality ratings for its portfolio securities provided by Moody's, S&P and Fitch. If all three of Moody's, S&P, and Fitch provide a rating for a security, the middle is used; if two of the three agencies rate a security, the lower rating is used; and if only one rating agency rates a security, that rating is used. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. Credit ratings are subject to change. Holdings designated N/R are not rated by Moody's, S&P or Fitch. Ratings are not covered by the report of independent registered public accounting firm.
(3)	Investment, or a portion of investment, is out on loan for securities lending. The total value of the securities out on loan as of the end of the reporting period was $1,323,236.
(4)	Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(5)	The Fund may loan securities representing up to one third of the market value of its total assets (which includes collateral for securities on loan) to broker dealers, banks, and other institutions. The collateral maintained by the Fund shall have a market value, at the inception of each loan, equal to not less than 100% of the market value of the loaned securities. The cash collateral received by the Fund is invested in this money market fund.
(6)	The rate shown is the one-day yield as of the end of the reporting period.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
DD1	Portion of investment purchased on a delayed delivery basis.
WI/DD	Purchased on a when-issued or delayed delivery basis.

Notes to Financial Statements

1. General Information

Trust and Fund Information

Nushares ETF Trust (the “Trust”) is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Trust is comprised of Nuveen Enhanced Yield U.S. Aggregate Bond ETF (NUAG), Nuveen Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF (NUSA), Nuveen ESG High Yield Corporate Bond ETF (NUHY) and Nuveen ESG U.S. Aggregate Bond ETF (NUBD) (each a “Fund” and collectively, the “Funds”), as diversified funds, among others. The Trust was organized as a Massachusetts business trust on February 20, 2015. Shares of the Funds are listed and traded on the NYSE Arca (the “Exchange”).

The end of the reporting period for the Funds is July 31, 2021, and the period covered by these Notes to Financial Statements is the fiscal year ended July 31, 2021 (the "current fiscal period").

Investment Adviser and Sub-Adviser

The Funds' investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America ("TIAA"). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds' portfolios, manages the Funds' business affairs and provides certain clerical, bookkeeping and other administrative services. The Adviser has entered into sub-advisory agreements with Teachers Advisors, LLC (the “Sub-Adviser”), an affiliate of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds.

Other Matters

The outbreak of the novel coronavirus (“COVID-19”) and subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the calendar quarter ended March 31, 2020. The worldwide spread of COVID-19 has created significant uncertainty in the global economy. The duration and extent of COVID-19 over the long term cannot be reasonably estimated at this time. The ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Funds' normal course of business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Management continues to monitor and evaluate this situation.

2. Significant Accounting Policies

The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. Each Fund is an investment company and follows accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services — Investment Companies. The NAV for financial reporting purposes may differ from the NAV for processing security and creation unit transactions. The NAV for financial reporting purposes includes security and creation unit transactions through the date of the report. Total return is computed based on the NAV used for processing security and creation unit transactions. The following is a summary of the significant accounting policies consistently followed by the Funds.

Compensation

The Trust pays no compensation directly to those of its trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Trust from the Adviser or its affiliates. The Funds' Board of Trustees (the "Board") has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

Distributions to Shareholders

Distributions to shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Indemnifications

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Trust enters into contracts that provide general indemnifications to other parties. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Investments and Investment Income

Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Interest Income, which is recorded on an accrual basis and includes accretion of discounts and amortization of premiums for financial reporting purposes. Interest income also reflects payment-in-kind ("PIK") interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash. Securities lending income is comprised of fees earned from borrowers and income earned on cash collateral investments.

New Accounting Pronouncements and Rule Issuances

Reference Rate Reform

In March 2020, FASB issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The main objective of the new guidance is to provide relief to companies that will be impacted by the expected change in benchmark interest rates, when participating banks will no longer be required to submit London Interbank Offered Rate (LIBOR) quotes by the UK Financial Conduct Authority (FCA). The new guidance allows companies to, provided the only change to existing contracts are a change to an approved benchmark interest rate, account for modifications as a continuance of the existing contract without additional analysis. For new and existing contracts, the Funds may elect to apply the amendments as of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the amendments, is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Funds’ investments and has currently determined that it is unlikely the ASU’s adoption will have a significant impact on the Funds’ financial statements and various filings.

Securities and Exchange Commission (“SEC”) Adopts New Rules to Modernize Fund Valuation Framework

In December 2020, the SEC voted to adopt a new rule governing fund valuation practices. New Rule 2a-5 under the 1940 Act establishes requirements for determining fair value in good faith for purposes of the 1940 Act. Rule 2a-5 will permit fund boards to designate certain parties to perform fair value determinations, subject to board oversight and certain other conditions. Rule 2a-5 also defines when market quotations are “readily available” for purposes of Section 2(a)(41) of the 1940 Act, which requires a fund to fair value a security when market quotation are not readily available. The SEC also adopted new Rule 31a-4 under the 1940 Act, which sets forth the recordkeeping requirements associated with fair value determinations. Finally, the SEC is rescinding previously issued guidance on related issues, including the role of a board in determining fair value and the accounting and auditing of fund investments. Rule 2a-5 and Rule 31a-4 became effective on March 8, 2021, with a compliance date of September 8, 2022. A fund may voluntarily comply with the rules after the effective date, and in advance of the compliance date, under certain conditions. Management is currently assessing the impact of these provisions on the Funds' financial statements.

3. Investment Valuation and Fair Value Measurements

The Funds' investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. U.S. GAAP establishes the three-tier hierarchy which is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect management’s assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).

Level 3 – Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

A description of the valuation techniques applied to the Funds’ major classifications of assets and liabilities measured at fair value follows:

Prices of fixed-income securities are provided by an independent pricing service (“pricing service”) approved by the Board. The pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity provided by the Adviser. These securities are generally classified as Level 2.

Investments in investment companies are valued at their respective NAVs on the valuation date and are generally classified as Level 1.

Any portfolio security or derivative for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued at fair value, as determined in good faith using procedures approved by the Board. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be consid-

Notes to Financial Statements (continued)

ered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. To the extent the inputs are observable and timely, the values would be classified as Level 2 of the fair value hierarchy; otherwise they would be classified as Level 3.

The following table summarizes the market value of the Funds' investments as of the end of the reporting period, based on the inputs used to value them:

4. Portfolio Securities and Investments in Derivatives

Securities Lending

Effective September 4, 2020, each Fund may lend securities representing up to one-third of the value of its total assets to broker-dealers, banks, and other institutions in order to generate additional income. When loaning securities, the Fund retains the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the security. The loans are continuous, can be recalled at any time, and have no set maturity. State Street Bank and Trust Company, serves as the securities lending agent (the “Agent”).

When a Fund loans its portfolio securities, it will receive, at the inception of each loan, cash collateral equal to an amount not less than 100% of the market value of the loaned securities. The actual percentage of the cash collateral will vary depending upon the asset type of the loaned securities.

Table of Contents

Collateral for the loaned securities is invested in a government money market vehicle maintained by the Agent, which is subject to the requirements of Rule 2a-7 under the 1940 Act. The value of the loaned securities and the liability to return the cash collateral received are recognized on the Statement of Assets and Liabilities. If the market value of the loaned securities increases, the borrower must furnish additional collateral to the Fund, which is also recognized on the Statement of Assets and Liabilities. Securities out on loan are subject to termination at any time at the option of the borrower or the Fund. Upon termination, the borrower is required to return to the Fund securities identical to the securities loaned. During the term of the loan, the Fund bears the market risk with respect to the investment of collateral and the risk that the Agent may default on its contractual obligations to the Fund. The Agent bears the risk that the borrower may default on its obligation to return the loaned securities as the Agent is contractually obligated to indemnify the Fund if at the time of a default by a borrower some or all of the loan securities have not been returned.

Securities lending income recognized by a Fund consists of earnings on invested collateral and lending fees, net of any rebates to the borrower and compensation to the Agent. Such income is recognized on the Statements of Operations.

As of the end of the reporting period, the total value of the loaned securities and the total value of collateral received were as follows:

Fund	Asset Class out on Loan	Long-Term Investments, at Value	Total Collateral Received
NUAG	Corporate Debt	$ 448,892	$ 458,901
	Government Related	223,266	227,813
	U.S. Treasury	899,367	918,000
Total		$1,571,525	$1,604,714
NUSA	Corporate Debt	$ 271,949	$ 277,750
NUHY	Corporate Debt	$1,796,839	$1,871,599
NUBD	Corporate Debt	$1,133,642	$1,155,817
	Municipal Bonds	189,594	193,545
Total		$1,323,236	$1,349,362

Zero Coupon Securities

A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically.

Investment Transactions

Long-term purchases and sales (including maturities, but excluding in-kind transactions) during the current fiscal period were as follows:

	NUAG	NUSA	NUHY	NUBD
Purchases:
Investment securities	$336,115,125	$17,880,458	$47,634,058	$101,132,408
U.S. Government and agency obligations	84,446,726	2,993,947	—	14,729,813
Sales and maturities:
Investment securities	281,442,459	15,647,655	50,411,127	57,052,264
U.S. Government and agency obligations	53,669,109	2,659,441	—	9,688,504

In-kind transactions during the current fiscal period were as follows:

	NUAG	NUSA	NUHY	NUBD
In-kind purchases	$262,695,556	$5,328,583	$41,195,732	$72,676,828
In-kind sales	243,036,013	2,645,939	—	—

The Funds may purchase securities on a when-issued or delayed-delivery basis. Securities purchased on a when-issued or delayed-delivery basis may have extended settlement periods; interest income is not accrued until settlement date. Any securities so purchased are subject to market fluctuation during this period. The Funds have earmarked securities in their portfolios with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. If a Fund has outstanding when-issued/delayed-delivery purchases commitments as of the end of the reporting period, such amounts are recognized on the Statement of Assets and Liabilities.

Notes to Financial Statements (continued)

Investments in Derivatives

Each Fund is authorized to invest in certain derivative instruments. The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds' investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.

Although each Fund is authorized to invest in derivative instruments, and may do so in the future, they did not make any such investments during the current fiscal period.

Market and Counterparty Credit Risk

In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.

Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.

5. Fund Shares

Each Fund issues and redeems its shares on a continuous basis at NAV only in aggregations of a specified number of shares or multiples thereof (“Creation Units”). Only certain institutional investors (referred to as “Authorized Participants”) who have entered into agreements with Nuveen Securities, LLC, the Funds' distributor, may purchase and redeem Creation Units. Once created, shares of the Funds trade on the Exchange at market prices and are only available to individual investors through their brokers.

Creation Units are purchased and redeemed in-kind for a designated portfolio of securities included in each Fund’s respective Index and/or a specified amount of cash. Authorized Participants are charged fixed transaction fees in connection with purchasing and redeeming Creation Units. Authorized Participants transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant Fund for certain transaction costs (i.e., taxes on currency or other financial transactions, and brokerage costs) and market impact expenses it incurs in purchasing or selling portfolio securities. Such variable charges, if any, are included in “Proceeds from shares sold” on the Statements of Changes in Net Assets.

Transactions in Fund shares during the current and prior fiscal period were as follows:

6. Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required.

For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing certain gains and losses on investment transactions. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the NAVs of the Funds.

The table below presents the cost and unrealized appreciation (depreciation) of each Fund’s investment portfolio, as determined on a federal income tax basis, as of July 31, 2021.

	NUAG	NUSA	NUHY	NUBD
Tax cost of investments	$217,515,533	$40,871,015	$95,568,489	$260,609,294
Gross unrealized:
Appreciation	$ 911,367	$ 458,686	$ 1,478,855	$ 5,153,451
Depreciation	(544,627)	(195,841)	(793,132)	(1,790,213)
Net unrealized appreciation (depreciation) of investments	$ 366,740	$ 262,845	$ 685,723	$ 3,363,238

Permanent differences, primarily due to redemption in-kind, bond premium amortization adjustments, and paydowns resulted in reclassifications among the Funds' components of net assets as of July 31, 2021, the Funds' tax year end.

The tax components of undistributed net ordinary income and net long-term capital gains as of July 31, 2021, the Funds' tax year end, were as follows:

	NUAG	NUSA	NUHY	NUBD

7. Management Fees and Other Transactions with Affiliates

Management Fees

Each Fund’s management fee compensates the Adviser for its investment advisory services to the Funds.

Annual Investment Management Agreement Approval Process

(Unaudited)

At a meeting held on May 25-27, 2021 (the “May Meeting”), the Board of Trustees (the “Board” and each Trustee, a “Board Member”) of Nushares ETF Trust, which is comprised entirely of Board Members who are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) (the “Independent Board Members”), approved, for each Fund, the renewal of the management agreement (each, an “Investment Management Agreement”) with Nuveen Fund Advisors, LLC (the “Adviser”) pursuant to which the Adviser serves as the investment adviser to such Fund and the sub-advisory agreement (each, a “Sub-Advisory Agreement”) with Teachers Advisors, LLC (the “Sub-Adviser”) pursuant to which the Sub-Adviser serves as the sub-adviser to such Fund. Although the 1940 Act requires that continuances of the Advisory Agreements (as defined below) be approved by the in-person vote of a majority of the Independent Board Members, the May Meeting was held virtually through the internet in view of the health risks associated with holding an in-person meeting during the COVID-19 pandemic and governmental restrictions on gatherings. The May Meeting was held virtually in reliance on certain exemptive relief the Securities and Exchange Commission provided to registered investment companies providing temporary relief from the in-person voting requirements of the 1940 Act with respect to the approval of a fund’s advisory agreement in light of these challenges.

Following up to an initial two-year period, the Board considers the renewal of each Investment Management Agreement and Sub-Advisory Agreement on behalf of the applicable Fund on an annual basis. The Investment Management Agreements and Sub-Advisory Agreements are collectively referred to as the “Advisory Agreements” and the Adviser and the Sub-Adviser are collectively, the “Fund Advisers” and each, a “Fund Adviser.” Throughout the year, the Board and its committees meet regularly and, at these meetings, receive regular and/or special reports that cover an extensive array of topics and information that are relevant to its annual consideration of the renewal of the advisory agreements for the Nuveen funds. Such information may address, among other things, fund performance and risk information; the Adviser’s strategic plans; product initiatives for various funds; the review of the funds and investment teams; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers to the funds; valuation of securities; fund expenses; securities lending; liquidity management; and overall market and regulatory developments. The Board also seeks to meet periodically with the Nuveen funds’ sub-advisers and portfolio teams, when feasible.

In addition, in connection with the annual consideration of the advisory agreements for the Nuveen funds, the Board, through its independent legal counsel, requested and received extensive materials and information prepared specifically for its annual consideration of the renewal of such advisory agreements by the Adviser and by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials cover a wide range of topics including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of product actions taken during 2020 (such as mergers, liquidations, fund launches, changes to investment teams, and changes to investment policies); a review of each sub-adviser to the Nuveen funds and the applicable investment teams; an analysis of fund performance in absolute terms and as compared to the performance of certain peer funds and benchmarks with a focus on any performance outliers; an analysis of the fees and expense ratios of the Nuveen funds in absolute terms and as compared to those of certain peer funds with a focus on any expense outliers; a review of management fee schedules; a description of portfolio manager compensation; a review of the performance of various service providers; a description of various initiatives Nuveen had undertaken or continued during the year for the benefit of particular fund(s) and/or the complex; a description of the profitability or financial data of Nuveen and the sub-advisers to the Nuveen funds; and a description of indirect benefits received by the Adviser and the sub-advisers as a result of their relationships with the Nuveen funds. The information prepared specifically for the annual review supplemented the information provided to the Board and its committees and the evaluations of the Nuveen funds by the Board and its committees during the year.

In continuing its practice, the Board met prior to the May Meeting to begin its considerations of the renewal of the Advisory Agreements. Accordingly, on April 21-22, 2021 (the “April Meeting”), the Board met to review and discuss, in part, the performance of the Nuveen funds and the Adviser’s evaluation of each sub-adviser to the Nuveen funds. At the April Meeting, the Board Members asked questions and requested additional information that was provided for the May Meeting. The Board reviewed fund performance throughout the year and in its review, the Board recognized the volatile market conditions that occurred in early 2020 arising, in part, from the public health crisis caused by the novel coronavirus known as COVID-19 and the resulting impact on a fund’s performance for 2020 and thereafter. Accordingly, the Board considered performance data measured over various periods of time as summarized in more detail below.

The Independent Board Members considered the review of the advisory agreements for the Nuveen funds to be an ongoing process and employed the accumulated information, knowledge and experience the Board Members had gained during their tenure on the boards governing the Nuveen funds and working with the Adviser and sub-advisers in their review of the advisory agreements. The contractual arrangements are a result of multiple years of review, negotiation and information provided in connection with the boards’ annual review of the Nuveen funds’ advisory arrangements and oversight of the Nuveen funds.

Annual Investment Management Agreement Approval Process (Unaudited) (continued)

The Independent Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives from the Adviser or the Sub-Adviser were present. In connection with their annual review, the Independent Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements.

The Board’s decision to renew the Advisory Agreements was not based on a single identified factor, but rather the decision reflected the comprehensive consideration of all the information provided throughout the year and at the April and May Meetings, and each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the approval process. The following summarizes the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements as well as the Board’s conclusions.

A. Nature, Extent and Quality of Services

In evaluating the renewal of the Advisory Agreements, the Independent Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to the respective Fund with particular focus on the services and enhancements to such services provided during the last year. The Independent Board Members considered the Investment Management Agreements and the Sub-Advisory Agreements separately in the course of their review. With this approach, they considered the respective roles of the Adviser and the Sub-Adviser in providing services to the Funds.

The Board recognized that the Nuveen funds operate in a highly regulated industry and, therefore, the Adviser has provided a wide array of management, oversight and administrative services to manage and operate the funds, and the scope and complexity of these services have expanded over time as a result of, among other things, regulatory and other developments. The Board accordingly considered the extensive resources, tools and capabilities available to the Adviser to operate and manage the Nuveen funds. With respect to the Adviser, as a general matter, some of these services it and its affiliates provide to the Nuveen funds include, but are not limited to: product management (such as setting dividends, analyzing fund expenses, providing competitive analysis, and providing due diligence support); investment oversight, risk management and securities valuation services (such as overseeing and reviewing the various sub-advisers to the Nuveen funds and their investment teams; analyzing fund performance and risk data; overseeing operational and risk management; participating in financial statement, marketing and risk disclosures; providing daily valuation services and developing related valuation policies, procedures and methodologies; periodic testing of audit and regulatory requirements; participating in product development and management processes; participating in leverage management, liquidity monitoring and counterparty credit oversight; providing due diligence and overseeing fund accounting and custody providers; overseeing third party pricing services and periodically assessing investment and liquidity risks); fund administration (such as preparing fund tax returns and other tax compliance services; preparing regulatory filings; overseeing the funds’ independent public accountants and other service providers; analyzing products and enhancements; and managing fund budgets and expenses); oversight of shareholder services and transfer agency functions (such as overseeing transfer agent service providers which include registered shareholder customer service and transaction processing; overseeing proxy solicitation and tabulation services; and overseeing the production and distribution of financial reports by service providers); Board relations services (such as organizing and administering Board and committee meetings, preparing various reports to the Board and committees and providing other support services); compliance and regulatory oversight services (such as managing compliance policies; monitoring compliance with applicable fund policies and laws and regulations; devising internal compliance programs and a framework to review and assess compliance programs; evaluating the compliance programs of the various sub-advisers to the Nuveen funds and certain other service providers; responding to regulatory requests; and preparing compliance training materials); and legal support and oversight of outside law firms (such as helping to prepare and file registration statements and proxy statements; overseeing fund activities and providing legal interpretations regarding such activities; maintaining regulatory registrations and negotiating agreements with other fund service providers; and monitoring changes in regulatory requirements and commenting on rule proposals impacting investment companies).

In evaluating services, the Board reviewed various highlights of the initiatives the Adviser and its affiliates have undertaken or continued in 2020 to benefit the Nuveen complex and/or particular Nuveen funds and meet the requirements of an increasingly complex regulatory environment including, but not limited to:

•	Centralization of Functions – ongoing initiatives to centralize investment leadership, market approach and shared support functions within Nuveen and its affiliates in seeking to operate more effectively the business and enhance the services to the Nuveen funds;
•	Fund Improvements and Product Management Initiatives – continuing to proactively manage the Nuveen fund complex as a whole and at the individual fund level with an aim to continually improve product platforms and investment strategies to better serve shareholders through, among other things, rationalizing the product line and gaining efficiencies through mergers, repositionings and liquidations; launching new funds; reviewing and updating investment policies and benchmarks; and modifying portfolio management teams for various funds;
•	Investment Team Integrations – continuing to integrate and adjust the members of certain investment teams, in part, to allow greater access to tools and resources within the Nuveen organization and its affiliates;

101

Table of Contents

•	Capital Initiatives – continuing to invest capital to support new Nuveen funds with initial capital as well as to support existing funds and facilitate regulatory or logistical changes;
•	Liquidity Management – continuing to operate the liquidity management program of the applicable Nuveen funds including monitoring daily their liquidity profile and assessing annually the overall liquidity risk of such funds;
•	Compliance Program Initiatives – continuing efforts to mitigate compliance risk, increase operating efficiencies, implement enhancements to strengthen key compliance program elements and support international business growth and other corporate objectives;
•	Investment Oversight – preparing reports to the Board addressing, among other things, fund performance; market conditions; investment teams; new products; changes to mandates, policies and benchmarks; and other management proposals;
•	Risk Management and Valuation Services - continuing to oversee and manage risk including, among other things, conducting daily calculations and monitoring of risk measures across the Nuveen funds, instituting appropriate investment risk controls, providing risk reporting throughout the firm, participating in internal oversight committees, and continuing to implement an operational risk framework that seeks to provide greater transparency of operational risk matters across the complex as well as provide multiple other risk programs that seek to provide a more disciplined and consistent approach to identifying and mitigating Nuveen’s operational risks. Further, the securities valuation team continues, among other things, to oversee the daily valuation process of the portfolio securities of the funds, maintains the valuation policies and procedures, facilitates valuation committee meetings, manages relationships with pricing vendors, and prepares relevant valuation reports and designs methods to simplify and enhance valuation workflow within the organization;
•	Regulatory Matters – continuing efforts to monitor regulatory trends and advocate on behalf of Nuveen and/or the Nuveen funds, to implement and comply with new or revised rules and mandates and to respond to regulatory inquiries and exams;
•	Government Relations – continuing efforts of various Nuveen teams and Nuveen’s affiliates to develop policy positions on a broad range of issues that may impact the Nuveen funds, advocate and communicate these positions to lawmakers and other regulatory authorities and work with trade associations to ensure these positions are represented;
•	Business Continuity, Disaster Recovery and Information Security – continuing efforts of Nuveen to periodically test and update business continuity and disaster recovery plans and, together with its affiliates, to maintain an information security program designed to identify and manage information security risks, and provide reports to the Board, at least annually, addressing, among other things, management’s security risk assessment, cyber risk profile, potential impact of new or revised laws and regulations, incident tracking and other relevant information technology risk-related reports; and
•	Dividend Management Services – continuing to manage the dividends among the varying types of Nuveen funds within the Nuveen complex to be consistent with the respective fund’s product design and positioning in striving to deliver those earnings to shareholders in a relatively consistent manner over time as well as assisting in the development of new products or the restructuring of existing funds.

In its review, the Board recognized that Nuveen’s risk management, compliance, technology and operations capabilities are all integral to providing its investment management services to the Nuveen funds. Further, the Board noted the benefits to shareholders of investing in a Nuveen fund, as each Nuveen fund is a part of a large fund complex with a variety of investment disciplines, capabilities, expertise and resources available to navigate and support the funds including during stressed times as occurred in the market in the first half of 2020. The Board recognized the impact of the COVID-19 pandemic during the year and the adaptations required by service providers to continue to deliver their services to the Nuveen funds, including working remotely. In this regard, the Board noted the ability of the Adviser and the various sub-advisers to the Nuveen funds to provide continuously their services notwithstanding the significant disruptions caused by the pandemic. In addition to the services provided by the Adviser, the Board also considered the risks borne by the Adviser and its affiliates in managing the Nuveen funds, including entrepreneurial, operational, reputational, regulatory and litigation risks.

The Board further considered the division of responsibilities between the Adviser and the Sub-Adviser and recognized that the Sub-Adviser and its investment personnel generally are responsible for the management of each Fund’s portfolio under the oversight of the Adviser and the Board. The Board considered an analysis of the Sub-Adviser provided by the Adviser which included, among other things, the assets under management of the applicable investment team and changes thereto, a summary of the applicable investment team and changes thereto, the investment process and philosophy of the applicable investment team, the performance of the Nuveen funds sub-advised by the Sub-Adviser over various periods of time and a summary of any significant policy and/or other changes to the Nuveen funds sub-advised by the Sub-Adviser. The Board further considered at the May Meeting or prior meetings evaluations of the Sub-Adviser’s compliance programs and trade execution. The Board also considered the structure of investment personnel compensation programs and whether this structure provides appropriate incentives to act in the best interests of the respective Nuveen funds. The Board noted that the Adviser recommended the renewal of the Sub-Advisory Agreements.

Based on its review, the Board determined, in the exercise of its reasonable business judgment, that it was satisfied with the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement.

B. The Investment Performance of the Funds and Fund Advisers

In evaluating the quality of the services provided by the Fund Advisers, the Board also received and considered a variety of investment performance data of the Nuveen funds they advise. In evaluating performance, the Board recognized that performance data may differ significantly depending on the ending date selected, particularly during periods of market volatility, and therefore considered performance over a variety of time periods that may include full market cycles. In this regard, the Board reviewed, among other things, Fund performance over the quarter, one- and three-year periods ending December 31, 2020 (or for shorter periods available to the extent a Fund was not in existence during such periods) as well as performance data periods ending nearer to the May Meeting, including the quarter, one- and three-year periods ending March 31, 2021 (or for shorter periods available to the extent a Fund was not in existence during such periods). The performance data prepared for the annual review of the advisory agreements for the Nuveen funds supplemented the fund performance data that the Board received throughout the year at its meetings representing differing time periods. In its review, the Board took into account the discussions with representatives of the Adviser; the Adviser’s analysis regarding fund performance that occurred at these Board meetings with particular focus on funds that were considered performance outliers (both overperformance and underperformance); the factors contributing to the performance; and any recommendations or steps taken to address performance concerns. Regardless of the time period reviewed by the Board, the Board recognized that shareholders may evaluate performance based on their own holding periods which may differ from the periods reviewed by the Board and lead to differing results. For Nuveen funds that had changes in portfolio managers since 2018 or significant changes, among other things, to their investment strategies or policies since 2019, the Board reviewed certain performance data comparing the performance of such funds before and after such changes. In considering performance data, the Board is aware of certain inherent limitations with such data, including that differences between the objective(s), strategies and other characteristics of the Nuveen funds compared to certain peer groups and/or benchmark(s) as well as differences in the composition of the peer groups over time will necessarily contribute to differences in performance results and limit the value of the comparative information.

The Board also evaluated performance in light of various relevant factors, including, among other things, general market conditions, issuer-specific information, asset class information, leverage and fund cash flows. In relation to general market conditions, the Board recognized the significant market decline in the early part of 2020 in connection with, among other things, the impact of the COVID-19 pandemic and that such a period of underperformance and market volatility may significantly weigh on the longer term performance results. Accordingly, depending on the facts and circumstances including any differences between the respective Nuveen fund and its benchmark and/or peer group, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below that of its benchmark or peer group for certain periods. However, with respect to any Nuveen funds for which the Board had identified performance issues, the Board monitors such funds closely until performance improves, discusses with the Adviser the reasons for such results, considers whether any steps are necessary or appropriate to address such issues, and reviews the results of any steps undertaken.

The Board noted that each Fund, a Nuveen exchange-traded fund (“ETF”), is designed to track the performance of a specified index (the “Underlying Index”). In its review, the Board received and reviewed information addressing, among other things, the net asset value performance of each Fund, the performance of such Fund’s Underlying Index and parent index, such Fund’s relative performance compared to the performance of peer funds (the “Performance Peer Group”) and such Fund’s tracking error and excess return compared to its Underlying Index over certain periods. However, given each Fund’s investment objective of seeking investment results that correspond generally to the performance of its Underlying Index, the Board recognized that the extent to which a Fund tracked its benchmark was of greater relevance in assessing the performance for the Fund and therefore placed more emphasis on the tracking error and correlation data provided.

The Board’s determinations with respect to each Fund are summarized below.

For Nuveen Enhanced Yield U.S. Aggregate Bond ETF (the “Enhanced Yield Fund”), the Board considered, among other things, the performance of the Fund and its Underlying Index for the one- and three-year periods ended December 31, 2020 and March 31, 2021 as well as its tracking error compared to its Underlying Index as of such dates. The Board noted that the Fund ranked in the second quartile of its Performance Peer Group for the one- and three-year periods ended December 31, 2020. In addition, the Fund ranked in the second quartile of its Performance Peer Group for the one-year period ended March 31, 2021 and the third quartile of its Performance Peer Group for the three-year period ended March 31, 2021. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. Based on its review, the Board was satisfied with the Fund’s overall performance.

For Nuveen Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF (the “Enhanced Yield 1-5 Year Fund”), the Board considered, among other things, the performance of the Fund and its Underlying Index for the one- and three-year periods ended December 31, 2020 and March 31, 2021 as well as its tracking error compared to its Underlying Index as of such dates. The Board noted that the Fund ranked in the second quartile of its Performance Peer Group for the one-year period ended December 31, 2020 and third quartile for the three-year period ended December 31, 2020. The Fund also ranked

103

Table of Contents

in the third quartile of its Performance Peer Group for the one- and three-year periods ended March 31, 2021. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. Based on its review, the Board was satisfied with the Fund’s overall performance.

For Nuveen ESG High Yield Corporate Bond ETF (the “ESG High Yield Fund”), the Board considered, among other things, the performance of the Fund and its Underlying Index for the one-year periods ended December 31, 2020 and March 31, 2021 as well as its tracking error compared to its Underlying Index as of such dates. The Board noted that the Fund ranked in the third quartile of its Performance Peer Group for such periods. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. Based on its review, the Board was satisfied with the Fund’s overall performance.

For Nuveen ESG U.S. Aggregate Bond ETF (the “ESG Aggregate Bond Fund”), the Board considered, among other things, the performance of the Fund and its Underlying Index for the one- and three-year periods ended December 31, 2020 and March 31, 2021 as well as its tracking error compared to its Underlying Index as of such dates. The Board noted that the Fund ranked in the second quartile of its Performance Peer Group for the one-year period ended December 31, 2020 and third quartile for the three-year period ended December 31, 2020. In addition, the Fund ranked in the fourth quartile of its Performance Peer Group for the one-year period ended March 31, 2021 and third quartile for the three-year period ended March 31, 2021. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. Based on its review, the Board was satisfied with the Fund’s overall performance.

C. Fees, Expenses and Profitability

1. Fees and Expenses

As part of its annual review, the Board generally considered the contractual management fee and net management fee (the management fee after taking into consideration fee waivers and/or expense reimbursements, if any) paid by a Nuveen fund to the Adviser in light of the nature, extent and quality of the services provided. The Board also generally considered the total operating expense ratio of a Nuveen fund before and after any fee waivers and/or expense reimbursements. With respect to the Nuveen ETFs, such as the Funds, however, the Board recognized that a Nuveen ETF pays a unitary fee and therefore, the Board reviewed the unitary fee compared to the gross and net management fees and net total expense ratios of a group of comparable funds (the “Peer Group”) established by Broadridge. The Independent Board Members reviewed the methodology Broadridge employed to establish its Peer Group and recognized that differences between the applicable fund and its respective Peer Group as well as changes to the composition of the Peer Group from year to year may limit some of the value of the comparative data. The Independent Board Members also considered a fund’s operating expense ratio as it more directly reflected the shareholder’s costs in investing in the respective fund.

In their review, the Independent Board Members considered, in particular, each fund with a net expense ratio of six basis points or higher compared to that of its peer average (each, an “Expense Outlier Fund”), including the ESG Aggregate Bond Fund, and an analysis as to the factors contributing to each such fund’s higher relative net expense ratio. Accordingly, in reviewing the comparative data between a fund and its peers, the Board generally considered the fund’s net expense ratio and fees to be higher if they were over 10 basis points higher, slightly higher if they were 6 to 10 basis points higher, in line if they were within approximately 5 basis points higher than the peer average and below if they were below the peer average of the Peer Group. The Independent Board Members also considered, in relevant part, a fund’s net management fee and net total expense ratio in light of its performance history.

As noted above, the Board recognized that the Nuveen ETFs pay the Adviser a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the Nuveen ETFs, subject to certain exceptions. Unlike the typical fee arrangements of the other Nuveen funds in which the funds pay a variety of fees and expenses such as investment advisory fees, transfer agency fees, audit fees, custodian fees, administration fees, compliance expenses, recordkeeping expenses, marketing and shareholder service fees, distribution charges and other expenses, Nuveen ETFs pay the Adviser a unified fee, and the Adviser is responsible for providing such services or arranging and supervising third parties to provide such services (subject to the certain exceptions). Under the unified fee structure, the Board recognized that the Adviser generally bears the risks of the operating costs rising (and benefits if such expenses decrease) and therefore has an incentive to be administratively efficient. As part of the Board’s analysis of the fee level of a Fund, the Independent Board Members reviewed, among other things, the unified fee compared to the gross and net management fees and net total expense ratios of its respective Peer Group.

With respect to the Sub-Adviser, the Board also considered the sub-advisory fee schedule paid to the Sub-Adviser in light of the sub-advisory services provided to the respective Fund and comparative data of the fees the Sub-Adviser charges to other clients, if any. In its review, the Board recognized that the compensation paid to the Sub-Adviser is the responsibility of the Adviser, not the Funds.

The Independent Board Members noted that (a) the Enhanced Yield Fund and the Enhanced Yield 1-5 Year Fund each had a net management fee and a net expense ratio that were below the respective peer averages; (b) the ESG High Yield Fund had a net management fee and a net expense ratio that were in line with the respective peer averages; and (c) the ESG Aggregate Bond Fund had a net management fee and a net expense ratio that were higher than the respective peer averages. The Independent Board Members noted that the ESG Aggregate Bond Fund’s relative stand-

Annual Investment Management Agreement Approval Process (Unaudited) (continued)

ing in its peer set changed, in part, due to a reduction in the average net expense ratio of the peer set related to an increase in the average net assets of the peer set and differences in investment strategies of the peer set relative to such Fund.

Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.

2. Comparisons with the Fees of Other Clients

In determining the appropriateness of fees, the Board also considered information regarding the fee rates the respective Fund Advisers charged to certain other types of clients and the type of services provided to these other clients. With respect to the Adviser and/or the Sub-Adviser, such other clients may include foreign investment companies offered by Nuveen and sub-advised by the Sub-Adviser; and certain funds advised by the Sub-Adviser. The Board further noted that the Adviser also advised and the Sub-Adviser sub-advised additional ETFs sponsored by Nuveen.

The Board recognized that the Funds had an affiliated sub-adviser and, with respect to affiliated sub-advisers, reviewed, among other things, the range of fees assessed for foreign investment companies and ETFs offered by Nuveen. In addition, the Board reviewed the management fees and expense ratios of certain funds advised by the Sub-Adviser in the TIAA-CREF family of funds.

In considering the fee data of other clients, the Board recognized, among other things, the differences in the amount, type and level of services provided to the Nuveen funds relative to other clients as well as the differences in portfolio investment policies, investor profiles, account sizes and regulatory requirements, all of which contribute to the variations in the fee schedules. The Board recognized the breadth of services the Adviser had provided to the Nuveen funds compared to the other types of clients as the funds operate in a highly regulated industry with increasing regulatory requirements as well as the increased entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the funds. Further, with respect to ETFs, the Board considered that Nuveen ETFs were passively managed compared to the active management of the other Nuveen funds which contributed to the differences in fee levels between the Nuveen ETFs and other Nuveen funds. In general, higher fee levels reflect higher levels of service provided by the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that the Sub-Adviser’s fee is essentially for portfolio management services. The Board concluded the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.

3. Profitability of Fund Advisers

In their review, the Independent Board Members considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2020 and 2019. The Board reviewed, among other things, Nuveen’s net margins (pre-tax) (both including and excluding distribution expenses); gross and net revenue margins (pre- and post-tax and excluding distribution) from Nuveen funds only; revenues, expenses and net income (pre- and post-tax and before distribution expenses) of Nuveen for fund advisory services; and comparative profitability data comparing the operating margins of Nuveen compared to the adjusted operating margins of certain peers that had publicly available data and with the most comparable assets under management (based on asset size and asset composition) for each of the last two calendar years. In reviewing the peer comparison data, the Independent Board Members noted that Nuveen Investments, Inc.’s operating margins were on the low range compared to the total company adjusted operating margins of the peers. The Board also reviewed the revenues and expenses the Adviser derived from its ETF product line for the 2019 and 2020 calendar years.

In reviewing the profitability data, the Independent Board Members recognized the subjective nature of calculating profitability as the information is not audited and is dependent on cost allocation methodologies to allocate corporate-wide expenses to the Nuveen complex and its affiliates and to further allocate such Nuveen complex expenses between the Nuveen fund and non-fund businesses. Generally, fund-specific expenses are allocated to the Nuveen funds and partial fund-related expenses and/or corporate overhead and shared costs (such as legal and compliance, accounting and finance, information technology and human resources and office services) are partially attributed to the funds pursuant to cost allocation methodologies. The Independent Board Members reviewed a description of the cost allocation methodologies employed to develop the financial information, a summary of the history of changes to the methodology over the years from 2010 to 2020, and the net revenue margins derived from the Nuveen funds (pre-tax and including and excluding distribution) and total company margins from Nuveen Investments, Inc. compared to the firm-wide adjusted margins of the peers for each calendar year from 2010 to 2020. The Board had also appointed three Independent Board Members to serve as the Board’s liaisons, with the assistance of independent counsel, to review the development of the profitability data and any proposed changes to the cost allocation methodology prior to incorporating any such changes and to report to the full Board. The Board recognized that other reasonable and valid allocation methodologies could be employed and could lead to significantly different results. The Independent Board Members also considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between 2019 and 2020. The Board also noted the reinvestments Nuveen and/or its parent made into its business through, among other things, the investment of seed capital in certain Nuveen funds and continued investments in enhancements to information technology, portfolio accounting systems and the global trading platform.

Table of Contents

In reviewing the comparative peer data noted above, the Board considered that the operating margins of Nuveen Investments, Inc. were in the lower half of the peer group range; however, the Independent Board Members also recognized the limitations of the comparative data given that peer data is not generally public and the calculation of profitability is subjective and affected by numerous factors (such as types of funds a peer manages, its business mix, its cost of capital, the numerous assumptions underlying the methodology used to allocate expenses and other factors) that can have a significant impact on the results.

Aside from Nuveen’s profitability, the Board recognized that the Adviser is a subsidiary of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). Accordingly, the Board also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2020 and 2019 calendar years to consider the financial strength of TIAA. The Board recognized the benefit of an investment adviser and its parent with significant resources, particularly during periods of market volatility as experienced with the COVID-19 pandemic.

In addition to Nuveen, the Independent Board Members considered the profitability of the Sub-Adviser from its relationships with the Nuveen funds. In this regard, the Independent Board Members reviewed the Sub-Adviser’s revenues, expenses and net operating income for its advisory services to the Nuveen ETFs and Nuveen closed-end funds for 2020 and 2019.

In evaluating the reasonableness of the compensation, the Independent Board Members also considered any other ancillary benefits derived by the respective Fund Adviser from its relationship with the Nuveen funds as discussed in further detail below.

Based on a consideration of all the information provided, the Board noted that Nuveen’s and the Sub-Adviser’s level of profitability was acceptable and not unreasonable in light of the services provided.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

The Board considered whether there have been economies of scale with respect to the management of the Nuveen funds and whether these economies of scale have been appropriately shared with the funds. The Board recognized that although economies of scale are difficult to measure and certain expenses may not decline with a rise in assets, there are several methods to help share the benefits of economies of scale, including breakpoints in the management fee schedule, fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in Nuveen’s business which can enhance the services provided to the funds for the fees paid. The Board noted that Nuveen generally has employed these various methods, and the Board considered the extent to which the Nuveen funds will benefit from economies of scale as their assets grow. In this regard, the Board noted that, with respect to the Nuveen funds generally, although the management fee of the Adviser is typically comprised of a fund-level component and a complex-level component each with its own breakpoint schedule, the Nuveen ETFs do not have breakpoint schedules. The Board recognized that the Nuveen ETFs (including the Funds) pay a unified fee and as a result, any reduction in fixed costs associated with the management of these funds would benefit the Adviser. However, the Independent Board Members noted that the unified fee schedule provides shareholders with a level of certainty of the expenses of the Nuveen ETFs. The Independent Board Members considered that the unified fees generally provide inherent economies of scale because the Nuveen ETF would maintain a competitive fixed fee over the annual contract period even if the particular fund’s assets declined and/or operating costs rose. As the Nuveen ETFs do not have breakpoints, they do not participate in the complex-level fee programs.

The Independent Board Members also recognized the Adviser’s continued reinvestment in its business through various initiatives including maintaining a seed account available for investments into Nuveen funds and investing in its internal infrastructure, information technology and other systems that will, among other things, consolidate and enhance accounting systems, integrate technology platforms to support growth and efficient data processing, and further develop its global trading platform to enhance the investment process for the investment teams.

Based on its review, the Board concluded that the current fee arrangements together with the Adviser’s reinvestment in its business appropriately shared any economies of scale with shareholders. The Board further concluded that the absence of a fund-level and/or complex-level breakpoint schedule or arrangement (as applicable) was acceptable.

E. Indirect Benefits

The Independent Board Members received and considered information regarding other benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the Nuveen funds. In addition, the Independent Board Members also noted that various sub-advisers may engage in soft dollar transactions pursuant to which they may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds. However, the Board noted that the Sub-Adviser does not participate in soft dollar arrangements with respect to Nuveen fund portfolio transactions.

Annual Investment Management Agreement Approval Process (Unaudited) (continued)

Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable and within acceptable parameters.

F. Other Considerations

The Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including the Independent Board Members, concluded that the terms of each Advisory Agreement were fair and reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed.

G. Subsequent Board Actions

At a meeting held on September 20, 2021, given continued growth in Nuveen ESG ETFs and certain comparative fee data with other ESG ETFs in the industry, among other things, the Board approved a five basis point (0.05%) reduction in the unitary management fee for the ESG High Yield Fund and the ESG Aggregate Bond Fund, effective September 28, 2021.

Liquidity Risk Management Program

(Unaudited)

Discussion of the operation and effectiveness of the Funds’ liquidity risk management program

In compliance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the “Liquidity Rule”), each Fund covered in this Report has adopted and implemented a liquidity risk management program (the “Program”), which is designed to manage each Fund’s liquidity risk. The Program consists of various protocols for assessing and managing each Fund’s liquidity risk. The Funds’ Board of Directors (the “Board”) previously designated Nuveen Fund Advisors, LLC, the Funds’ investment adviser (the “Adviser”), as the administrator of the Program. The Adviser’s Liquidity Monitoring and Analysis Team (“LMAT”) carries out day-to-day Program management with oversight by the Adviser’s Liquidity Oversight Sub-Committee (“LOSC”). LMAT and LOSC are composed of personnel from the Adviser and Teachers Advisors, LLC, an affiliate of the Adviser.

At a May 26, 2021 meeting of the Board, the Adviser provided the Board with a written report addressing the Program’s operation, adequacy and effectiveness of implementation for the calendar year 2020 (the “Review Period”), as required under the Liquidity Rule. The report noted that the Program has been and continues to be adequately and effectively implemented to monitor and (as applicable) respond to each Fund’s liquidity developments.

In accordance with the Program, LMAT assesses each Fund’s liquidity risk no less frequently than annually based on various factors, such as (i) the Fund’s investment strategy and the liquidity of its portfolio investments, (ii) cash flow projections, and (iii) holdings of cash and cash equivalents, borrowing arrangements, and other funding sources. Certain factors are considered under both normal and reasonably foreseeable stressed conditions.

Each of the Funds’ portfolio investments are classified into one of four liquidity categories (including the most liquid, “Highly Liquid,” and the least liquid, “Illiquid,” as discussed below). The classification is based on a determination of how long it is reasonably expected to take to convert the investment into cash, or sell or dispose of the investment, in current market conditions without significantly changing the market value of the investment. Liquidity classification determinations take into account various market, trading, and investment-specific considerations, as well as market depth, using third-party vendor data.

A fund that does not primarily hold Highly Liquid investments must, among other things, determine a minimum percentage of the fund’s net assets that must be invested in Highly Liquid investments (a “Highly Liquid Investment Minimum”). During the Review Period, each Fund primarily held Highly Liquid investments and therefore was exempt from the requirement to adopt a Highly Liquid Investment Minimum and to comply with the related requirements under the Liquidity Rule.

The Liquidity Rule also limits a fund’s investments in Illiquid investments. Specifically, the Liquidity Rule prohibits a fund from acquiring Illiquid investments if doing so would result in the fund holding more than 15% of its net assets in Illiquid investments, and requires certain reporting to the fund’s board and the Securities and Exchange Commission any time a fund’s holdings of Illiquid investments exceeds 15% of net assets. During the Review Period, the Funds did not exceed the 15% limit on Illiquid investments.

PRINCIPAL ACCOUNTANT FEES AND SERVICES.

The following tables show the amount of fees that KPMG LLP, the Funds’ auditor, billed to the Funds’ during the Funds’ last two full fiscal years. The Audit Committee approved in advance all audit services and non-audit services that KPMG LLP provided to the Funds, except for those non-audit services that were subject to the pre-approval exception under Rule 2-01 of Regulation S-X (the “pre-approval exception”). The preapproval exception for services provided directly to the Funds waives the pre-approval requirement for services other than audit, review or attest services if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid by the Funds during the fiscal year in which the services are provided; (B) the Funds did not recognize the services as non-audit services at the time of the engagement; and (C) the services are promptly brought to the Audit Committee’s attention, and the Committee (or its delegate) approves the services before the audit is completed.

The Audit Committee has delegated certain pre-approval responsibilities to its Chair (or, in her absence, any other member of the Audit Committee).
