Chair’s Letter to Shareholders

Dear Shareholders,

The COVID-19 crisis is taking an unprecedented toll on our health, societies, economies and financial markets. Our thoughts are with you during this time of significant disruption caused by the disease and its economic fallout. With many regions of the world suppressing the initial spread of the virus, governments and public health officials face the extraordinary challenge of balancing the resumption of economic activity with public safety. New clusters of infection emerged in the U.S. and other countries following their reopening this summer while a new school year and Northern Hemisphere flu season have added new concerns. Nevertheless, an economic recovery has gained traction, as jobs, consumer spending, manufacturing and other indicators have begun to rebound from their weakest levels. Additionally, progress toward a vaccine has been promising, while the timeline is unknown. Markets have recently taken an optimistic view, bouts of elevated volatility are likely to continue, with economic data, coronavirus infection rates and the upcoming U.S. presidential election under scrutiny.

While we do not want to understate the dampening effect on the global economy, it is important to differentiate short-term interruptions from the longer-lasting implications to the economy. Prior to the COVID-19 crisis, some areas of the global economy were showing signs of improvement after trade tensions had weighed on economic activity for much of 2019. More recently, countries that have reopened have seen marked improvement in some near-term economic indicators. Central banks and governments around the world have announced economic stimulus measures and pledged to continue doing what it takes to support their economies. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced similar programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. Government has approved three relief packages, including a $2 trillion-dollar package directly supporting businesses and individuals. The Coronavirus Aid, Relief and Economic Security Act, called the CARES Act, has provided direct payments and expanded unemployment benefits to individuals, loans and grants to small businesses, loans and other money to large corporations and funding for hospitals, public health, education and state and local governments. In the European Union, the European Central Bank recently increased the size of its Pandemic Emergency Purchase Program, known as PEPP, to $1.6 trillion from $878 billion and extended its duration to June 2021.

In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial professional, who can review your time horizon, risk tolerance and investment goals. 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.

Sincerely,

Terence J. Toth

Chair of the Board

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 they discuss U.S. economic and market conditions, key investment strategies and the twelve-month performance of the Funds.

What factors affected the U.S. economy and the bond market during the twelve-month annual reporting period ended July 31, 2020?

The longest economic expansion in U.S. history came to an abrupt halt in early 2020 amid the COVID-19 coronavirus pandemic. To slow the spread of the virus, large portions of the economy were shut down, with companies closing either temporarily or permanently and most of the U.S. population under stay-at-home orders during March and April 2020. A phased reopening began toward the end of May 2020, but the disruption to the economy has been swift and severe. In June 2020, the National Bureau of Economic Research announced that the economic expansion that began in June 2009 officially ended in February 2020, marking the start of a recession (a several months’ long contraction across the broad economy). As expected, the U.S. economy suffered a sharp contraction in the second quarter of 2020, with gross domestic product (GDP) down 32.9% on an annualized basis according to the Bureau of Economic Analysis “advance” estimate. GDP measures the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes. In the second quarter, steep declines in consumer spending, business investment and exports weighed on economic activity, offsetting increased government spending. By comparison, the annualized GDP growth rate shrank 5% in the first quarter of 2020, after expanding 2.4% in the fourth quarter of 2019 and 2.2% in 2019 overall.

Consumer spending, the largest driver of the economy, was well supported earlier in this reporting period by low unemployment, wage gains and tax cuts. However, the COVID-19 crisis containment measures drove a significant drop in consumer spending and a sharp rise in unemployment starting in March 2020. The Bureau of Labor Statistics said the unemployment rate rose to 10.2% in July 2020 from 3.7% in July 2019. The economy added 1.8 million jobs in July, but non-farm employment remained 12.9 million below the February 2020 level. The average hourly earnings rate appeared to soar, growing at an annualized rate of 4.8% in July 2020, despite the spike in unemployment. Earnings data were skewed by the concentration of job losses in lower-wage work, which effectively elimi-

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.

nated most of the low-wage data, resulting in an average of mostly higher numbers. The overall trend of inflation weakened considerably, which was attributed to large decreases in gasoline, apparel, air travel and lodging prices offsetting an increase in food prices. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 1.0% over the twelve-month ended July 31, 2020 before seasonal adjustment.

Low mortgage rates and low inventory drove home prices moderately higher in this reporting period, although the period measured only partially reflects the shutdown. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, was up 4.3% year-over-year in June 2020 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 2.8% and 3.5%, respectively.

With economic momentum slowing in 2019 from 2018’s stronger pace, the U.S. Federal Reserve (Fed) cut its benchmark interest rate by 0.25% at each of the July 2019, September 2019 and October 2019 policy committee meetings. Markets registered disappointment with the Fed’s explanation that the rate cuts were a “mid-cycle adjustment,” rather than a prolonged easing period, and its signal that there would be no additional rate cuts in 2019. Also in the latter half of 2019, the Fed announced it would stop shrinking its bond portfolio sooner than scheduled, as well as began buying short-term Treasury bills to help money markets operate smoothly and maintain short-term borrowing rates at low levels. Fed Chairman Powell emphasized that the Treasury bill purchases were not a form of quantitative easing. The Fed continued its Treasury bill buying in January 2020, as well as left its benchmark interest rate unchanged, while noting the emerging COVID-19 risks.

As the outbreak spread to the U.S. and significant restrictions on social and economic activity were imposed starting in March 2020, the Fed enacted an array of emergency measures to stabilize the financial system and support the markets, including cutting its main interest rate to near zero, offering lending programs to aid small and large companies and allowing unlimited bond purchases, known as quantitative easing. There were no policy changes at the Fed’s April, June and July 2020 meetings, where Chairman Powell reiterated a commitment to keep rates near zero until the economy recovers and continued to issue a cautious outlook for the U.S. economy. Also at the July meeting, the Fed extended some of its pandemic funding facilities by another three months to December 2020.

Meanwhile, the U.S. government approved three aid packages, totaling more than $100 billion in funding to health agencies and employers offering paid leave and $2 trillion allocated across direct payments to Americans, an expansion of unemployment insurance, loans to large and small businesses, funding to hospitals and health agencies and support to state and local governments.

While trade and tariff policy drove market sentiment for most of the twelve-month reporting period, the outbreak of the novel coronavirus and its associated disease COVID-19 rapidly dwarfed all other market concerns starting in late February 2020. Equity and commodity markets sold-off and safe-haven assets rallied in March 2020 as China, other countries and then the United States initiated quarantines, restricted travel and shuttered factories and businesses. The potential economic shock was particularly difficult to assess, which amplified market volatility. An ill-timed oil price war between the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC member Russia, which caused oil prices to plunge in March 2020, exacerbated the market sell-off.

Outside the U.S., many countries implemented lockdowns and restrictions on business activity to reduce infection rates, with a deep impact to their economies. Pandemic responses included central bank monetary easing and quantitative easing, fiscal relief programs, the loosening of fiscal rules and, in the case of emerging markets, emergency financing and debt relief from bilateral creditors and international organizations such as the International Monetary Fund and World Bank. The U.K. formally exited the European Union (EU) at the end of January 2020, triggering the one-year transition period, but Brexit talks were temporarily paused during the virus lockdown. When negotiations resumed, the U.K. continued to indicate it would not seek an extension. Italy’s prime minister unexpectedly resigned in August 2019, and the newly formed coalition government appeared to take a less antagonistic stance towards the EU. To help relieve the COVID-19 crisis impact on Italy and other more indebted Southern European countries, the European Commission proposed a €750 billion aid program to be funded by all member states, which was unanimously approved in July 2020. In Asia, northern countries were among the first to successfully reduce infection rates and relax COVID-19 crisis restrictions, but pockets of the disease re-emerged. The widespread anti-government protests roiling Hong Kong throughout 2019 had dissipated amid the lockdown, but tensions flared in late May 2020 when China unexpectedly announced a national security law perceived as a threat to Hong Kong’s sovereignty. India took stringent lockdown steps in March 2020 but still saw a rapid increase in cases. Latin American countries

entered the health crisis in already weakened positions, with high government debt and widespread civil unrest. Venezuela’s economic and political crisis continued to deepen. Argentina surprised the market with the return of a less market-friendly administration but continued to pursue a restructuring of its debt. Brazil’s Bolsonaro administration achieved a legislative win on pension reform but had not fully delivered on reviving economic growth. As COVID-19 spread to Latin America, the inconsistent government responses, reduced testing capabilities, weaker health care systems, food shortages and public protests contributed to accelerating infection and death rates.

Prior to the COVID-19 crisis, global markets had become more bullish on the outlook for 2020 as trade policy and Brexit appeared to make progress at the end of 2019. The U.S. and China agreed on a partial trade deal, which included rolling back some tariffs, increasing China’s purchases of U.S. agriculture products and the consideration of intellectual property, technology and financial services rights. The “phase one” deal was signed on January 15, 2020. While much of the focus remained on the U.S.-China relationship, trade spats between the U.S. and Mexico, the EU, Brazil and Argentina also arose throughout the reporting period. In January 2020, the U.S. Congress fully approved the U.S., Mexico and Canada Agreement (USMCA), which replaces the North American Free Trade Agreement. With more clarity on trade deals, the trade-related deterioration in global manufacturing and export data was expected to improve. However, the COVID-19 crisis has since upended those assumptions. Furthermore, tensions between the U.S. and China escalated amid the COVID-19 crisis, with both sides stoking resentment about the management of the health crisis, Hong Kong’s sovereignty, trade policy and technology issues.

Performance was positive across U.S. bond markets during the twelve-month reporting period, driven by a substantial decline in yields. Prompt and aggressive action by the Fed and other global central banks to circumvent a liquidity crisis helped markets recover meaningfully from the March 2020 COVID-19 crisis sell-off. Notably during the reporting period, government bonds benefited from their status as safe-haven assets while non-government sectors, such as corporate bonds, also performed well as investors sought higher yielding assets despite the economic uncertainty arising from the COVID-19 crisis.

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

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 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 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. 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. As of July 31, 2020, the Fund’s net assets were invested in 40.3% securitized debt, 30.8% corporate debt, 23.4% U.S. Treasuries and 4.7% government-related debt.

How did the Fund perform during the twelve-month reporting period ended July 31, 2020?

The table in the Fund’s Performance Overview and Expense Ratios section of this report provides the Fund’s total return performance information for the one-year and since inception periods ended July 31, 2020. 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 outperformed the NUAG Enhanced Index during the reporting period.

Portfolio Managers’ Comments (continued)

The Fund’s relative outperformance during the reporting period is mainly attributable to the representative sampling process that utilizes a sub-set of Index securities in an effort to provide exposure similar to that of the NUAG Enhanced Index, which leads the Fund to be overweight, 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, as well as fees and expenses incurred by the Fund that are not incurred by the NUAG Enhanced Index reduce relative performance. 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.

Fixed income markets posted strong performance for the twelve-month reporting period overall, despite the significant market volatility driven by the COVID-19 crisis uncertainty in March 2020. Prior to the advent of the health crisis, markets had been focused on the Feds three interest rate cuts in the second half of 2019, which were intended to help extend the economic cycle in the face of growing downside risks from trade tensions and weaker growth abroad. Economic and social activity restrictions to control the spread of COVID-19 drove a severe downward spiral in financial markets, including the corporate and municipal bond markets, in March 2020. The turmoil was short-lived, however. Massive monetary and fiscal interventions helped stabilize credit conditions and support investor sentiment, while economic indicators began to improve with the economy reopening in May 2020.

Yields fell across the yield curve, with the largest decline at the shorter end. Treasury yields on the 1-year bond fell to 0.11% as of July 31, 2020 from 2.01% on July 31, 2019, the 10-year fell to 0.54% from 2.02% and the 30-year fell to 1.20% from 2.53%. Corporate credit markets performed well during the reporting period, with spreads narrowing after a dramatic widening during the March 2020 sell-off. Investment grade issuance was particularly strong, as companies rushed to take advantage of the low interest rate environment. New supply was met with strong investor demand, which was enhanced by the Fed acting as a backstop to corporate credit markets. High yield corporate bonds performed well but underperformed the investment grade segment during the reporting period. Not surprisingly, in 2020 so far, credit ratings downgrades have increased and high yield default activity has risen, most prominently in the energy sector. Securitized markets also benefited from spread tightening, amid positive technicals aided by Fed support and better-than-expected mortgage market trends. However, assets with greater COVID-19 crisis exposure, such as retail and hotels, remained under stress.

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

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 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. The Fund rebalances its holdings monthly in response to the monthly NUSA Enhanced Index rebalances.

During the reporting period, the Fund has remained fully invested within its allocation targets to track the NUSA Enhanced Index. As of July 31, 2020, the Fund’s net assets were invested in 42.9% corporate debt, 30.1% securitized debt, 26.1% U.S. Treasuries, and 1.5% government-related debt.

Nuveen ESG High Yield Corporate Bond ETF (NUHY)

What key strategies were used to manage the Fund during the abbreviated 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 Barclays 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 Barclays 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. 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. To the extent the NUHY Select 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 NUHY Select Index. The Fund rebalances its holdings monthly in response to the monthly NUHY Select Index rebalances.

During the abbreviated reporting period, the Fund worked to fully invest within its allocation targets to track the NUHY Select Index. As of July 31, 2020, the Fund’s net assets were invested in the following corporate bond sectors: 88.3% industrials, 9.0% financial institutions and 0.5% utilities and 1.1% government agency debt.

Portfolio Managers’ Comments (continued)

How did the Fund perform during the abbreviated reporting period ended July 31, 2020?

The table in the Fund’s Performance Overview and Expense Ratios section of this report provides the Fund’s total return performance for the abbreviated reporting period from the Fund’s commencement of operations on September 25, 2019 through July 31, 2020. The Fund’s total returns at net asset value (NAV) are compared with the performance of the NUHY Select Index, which the Fund is designed to track. The Fund’s total return trailed that of the NUHY Select Index over this abbreviated reporting period.

The Fund's relative underperformance is mainly attributable to the transaction costs related to the Fund’s acquisition of portfolio securities, as well as fees and expenses incurred by the Fund that are not incurred by the NUHY Select Index. Additionally, costs and expenses tend to be elevated during a Fund’s start-up phase when the portfolio is being fully invested, which is captured in this abbreviated reporting period. The NUHY Select 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.

The high yield corporate bond market managed positive performance during the abbreviated reporting period. Prior to the advent of the health crisis, markets had been focused on the Feds three interest rate cuts in the second half of 2019, which were intended to help extend the economic cycle in the face of growing downside risks from trade tensions and weaker growth abroad. Economic and social activity restrictions to control the spread of COVID-19 drove a severe downward spiral in financial markets, including the corporate and municipal bond markets, in March 2020.

High yield corporate bonds rebounded after a dramatic widening during the March 2020 sell-off. Not surprisingly in 2020, credit ratings downgrades have increased, and high yield default activity has risen, most prominently in the energy sector. However, high yield corporate bonds performed well, supported by investor demand for higher yielding assets, minimal negative surprises in the second quarter 2020 earnings season and improved sentiment, driven in part by the Fed acting as a backstop to the corporate bond market.

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. investment grade 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 Barclays MSCI U.S. Aggregate ESG Select Index (“the NUBD 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 NUBD Select Index. To the extent the NUBD Select 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 NUBD Select Index. The Fund rebalances its holdings monthly in response to the monthly NUBD Select Index rebalances.

During the reporting period, the Fund remained fully invested within its allocation targets to track the NUBD Select Index. As of July 31, 2020, the Fund’s net assets were invested in 37.2% U.S. Treasuries, 28.8% securitized debt, 27.4% corporate debt and 5.8% government-related debt.

The Fund’s relative outperformance is mainly attributable to the representative sampling process that utilizes a sub-set of Index securities in an effort to provide exposure similar to that of the NUBD Select Index, which leads the Fund to be overweight, 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, as well as fees and expenses incurred by the Fund that are not incurred by the NUBD Select Index reduce relative performance. The NUBD Select 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.

Fixed income markets posted strong performance for the twelve-month reporting period overall, despite the significant market volatility driven by the COVID-19 crisis uncertainty in March 2020. Prior to the advent of the health crisis, markets had been focused on the Federal Reserve’s three interest rate cuts in the second half of 2019, which were intended to help extend the economic cycle in the face of growing downside risks from trade tensions and weaker growth abroad. Economic and social activity restrictions to control the spread of COVID-19 drove a severe downward spiral in financial markets, including the corporate and municipal bond markets, in March 2020. The turmoil was short-lived, however. Massive monetary and fiscal interventions helped stabilize credit conditions and support investor sentiment, while economic indicators began to improve with the economy reopening in May 2020.

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.

Total returns for a period of less than one year are not annualized (i.e. cumulative returns). Returns assume reinvestment of dividends and capital gains. Market price returns are based on the closing market price as of the end of the reporting period. For performance current to the most recent month-end visit nuveen.com or call (800) 257-8787.

Returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares.

Yields as of July 31, 2020

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, 2020

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, 2020.

The beginning of the period is February 1, 2020.

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.

	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.

	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.

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, 2020, and the period covered by these Notes to Financial Statements for NUAG, NUSA and NUBD is the fiscal year ended July 31, 2020 and for NUHY is September 25, 2019 (commencement of operations) through July 31, 2020 (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 net asset value (“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.

Table of Contents

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. Investment income is comprised of interest income, which reflects the amortization of premiums and includes accretion of discounts for financial reporting purposes and, is recorded on an accrual basis. Investment 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.

New Accounting Pronouncements and Rule Issuances

FASB Accounting Standards Update (“ASU”) 2017-08 (“ASU 2017-08”) Premium Amortization on Purchased Callable Debt Securities

The FASB has issued ASU 2017-08, which shortens the premium amortization period for purchased non-contingently callable debt securities. ASU 2017-08 specifies that the premium amortization period ends at the earliest call date, for purchased non-contingently callable debt securities. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. During the current fiscal period, ASU 2017-08 became effective for the Funds and it did not have a material impact on the Funds' financial statements.

Fair Value Measurement: Disclosure Framework

During August 2018, the FASB issued ASU 2018-13 (“ASU 2018-13”), Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements. ASU 2018-13 modifies the disclosures required by Topic 820, Fair Value Measurements. The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Management has early implemented this guidance and it did not have a material impact on the Funds' financial statements.

Reference Rate Reform

In March 2020, FASB issued 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 at the end of 2021, 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 changes 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 optional expedients as of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the optional expedients, but is currently assessing the impact of the ASU’s adoption to the Funds' financial statements and various filings.

3. Investment Valuation and Fair Value Measurements

The fair valuation input levels as described below are for fair value measurement purposes.

The Funds' investments in securities are recorded at their estimated fair value. 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. A three-tier hierarchy 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 the reporting entity’s own 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).

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. These securities are generally classified as Level 2. 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 or Level 3 depending on the observability of the significant inputs.

Table of Contents

Notes to Financial Statements (continued)

Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Board and/or its appointee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. 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 considered 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. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Board and/or its appointee.

The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of each Fund’s fair value measurements as of the end of the reporting period:

4. Portfolio Securities and Investments in Derivatives

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	$233,162,765	$22,231,440	$27,105,077	$88,418,231
U.S. Government and agency obligations	42,557,768	11,491,037	—	—
Sales and maturities:
Investment securities	224,868,780	11,612,020	20,974,858	16,556,183
U.S. Government and agency obligations	29,798,835	4,665,818	—	364,884

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

	NUAG	NUSA	NUHY	NUBD
In-kind purchases	$226,736,464	$ —	$50,167,038	$15,320,343
In-kind sales	237,459,350	9,682,822	—	2,776,344

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.

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.

Notes to Financial Statements (continued)

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 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, 2020.

	NUAG	NUSA	NUHY	NUBD
Tax cost of investments	$79,151,442	$35,181,343	$55,160,357	$141,863,175
Gross unrealized:
Appreciation	$ 2,589,133	$ 918,359	$ 1,334,601	$ 8,734,833

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, 2020, the Funds' tax year end.

The tax components of undistributed net ordinary income and net long-term capital gains as of July 31, 2020, the Funds' tax year end, were as follows:

	NUAG	NUSA	NUHY	NUBD
Undistributed net ordinary income¹	$220,238	$92,174	$316,622	$328,878
Undistributed net long-term capital gains	—	—	—	—

¹	Net ordinary income consists of net taxable income derived from dividends, interest, and net short-term capital gains, if any.

The tax character of distributions paid during the Funds' tax years ended July 31, 2020 and July 31, 2019 was designated for purposes of the dividends paid deduction as follows:

2020	NUAG	NUSA	NUHY ²	NUBD
Distributions from net ordinary income¹	$3,772,060	$894,030	$1,805,740	$2,152,900

¹	Net ordinary income consists of net taxable income derived from dividends, interest, and net short-term capital gains, if any.
²	For the period September 25, 2019 (commencement of operations) through July 31, 2020.

As of July 31, 2020, the Funds’ tax year end, the Funds had unused capital losses carrying forward available for federal income tax purposes to be applied against future capital gains, if any. The capital losses are not subject to expiration.

	NUAG	NUSA	NUHY	NUBD

	NUAG	NUSA
Utilized capital loss carryforwards	$413,529	$41,970

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. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser. The Adviser is responsible for substantially all other expenses of the Funds, except any future distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities, fees and expenses of the independent trustees (including any trustees’ counsel fees), certain compensation expenses of the Funds’ chief compliance officer, litigation expenses and extraordinary expenses.

The annual management fee, payable monthly, for each Fund is based on a percentage of average daily net assets according to the following rates:

Fund	Management Fee
NUAG	0.20%
NUSA	0.20

Glossary of Terms Used in this Report

(Unaudited)

Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.

Bloomberg Barclays MSCI U.S. Aggregate ESG Select Index: The Index is composed of U.S. investment grade fixed income securities that satisfy certain ESG and low-carbon criteria, including 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. governments and corporations that are publicly offered for sale in the U.S. The index returns assume reinvestment of dividends, but do not include the effects of any sales charges or management fees.

Bloomberg Barclays MSCI U.S. High Yield Very Liquid ESG Select Index: An index designed to utilize certain environmental, social, and governance (ESG) criteria to select from the securities included in the Bloomberg Barclays U.S. High Yield Very Liquid Index, which is designed to broadly capture the U.S. dollar-denominated, high yield, fixed-rate corporate bond market. The Index is rebalanced monthly. It is not possible to invest directly in an index.

Bloomberg Barclays U.S. Aggregate Bond Index: The index covers the U.S. investment grade fixed rate bond market, with index components for government and corporate securities, mortgage pass through securities and asset-backed securities. These major sectors are subdivided into more specific indexes that are calculated and reported on a regular basis. Index returns assume reinvestment of distributions, but do not include the effects of any applicable sales charges or management fees.

Bloomberg Barclays U.S. Government/Credit 1-5 Year Bond Index: An index that measures the performance of U.S. dollar-denominated U.S. Treasury bonds, government related bonds and investment grade U.S. corporate bonds that have a remaining maturity of greater than or equal to one year and less than five years. Index returns assume reinvestment of distributions, but do not include the effects of any applicable sales charges or management fees.

Gross Domestic Product (GDP): The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.

ICE BofA Enhanced Yield U.S. Broad Bond Index: This index provides exposure to the broad U.S. investment grade bond market. This included U.S. government and Treasury debt as well corporate bonds.

Annual Investment Management Agreement Approval Process

The Board of Trustees of Nushares ETF Trust (the “Board,” and each Trustee, a “Board Member”), including the Board Members who are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) (the “Independent Board Members”), is responsible for determining whether to initially approve or, after an initial term, to renew, each Fund’s advisory arrangements. A discussion of the Board’s most recent approval of the renewal of the advisory arrangements for Nuveen Enhanced Yield U.S. Aggregate Bond ETF (the “Enhanced Yield U.S. Aggregate Bond ETF”), Nuveen Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF (the “Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF”) and Nuveen ESG U.S. Aggregate Bond ETF (the “ESG U.S. Aggregate Bond ETF”) is set forth in Part I below. The advisory arrangements for Nuveen ESG High Yield Corporate Bond ETF (the “ESG High Yield Corporate Bond ETF”) have not yet been up for renewal. A discussion of the Board’s initial approval of the advisory arrangements for the ESG High Yield Corporate Bond ETF is set forth in Part II below.

PART I

Nuveen Enhanced Yield U.S. Aggregate Bond ETF

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

Nuveen ESG U.S. Aggregate Bond ETF

At a meeting held on May 19-21, 2020 (the “May Meeting”), the Board, which is comprised entirely of Independent Board Members, approved, for the Enhanced Yield U.S. Aggregate Bond ETF, the Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF and the ESG U.S. Aggregate Bond ETF (for purposes of this Part I, collectively, the “Funds” and each, a “Fund”), the renewal of the management agreement (for purposes of this Part I, each, an “Investment Management Agreement”) with Nuveen Fund Advisors, LLC (the “Adviser”) pursuant to which the Adviser serves as the investment adviser to the respective Fund and the sub-advisory agreement (for purposes of this Part I, each, a “Sub-Advisory Agreement”) with Teachers Advisors, LLC (the “Sub-Adviser”) pursuant to which the Sub-Adviser serves as the investment sub-adviser to the respective 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 in reliance on an order issued by the Securities and Exchange Commission on March 13, 2020, as extended on March 25, 2020, which provided registered investment companies temporary relief from the in-person voting requirements of the 1940 Act with respect to the approval of a fund's advisory agreement in response to the challenges arising in connection with the COVID-19 pandemic.

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. For purposes of this Part I, 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, review 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; the Adviser’s strategic plans; 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; and overall market and regulatory developments.

In addition to the information and materials received during the year, the Board, in response to a request made on its behalf by independent legal counsel, received extensive materials and information prepared specifically for its annual consideration of the renewal of the advisory agreements for the Nuveen funds 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 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 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.

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 27-28, 2020 (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. In its review, the Board recognized the volatile market conditions occurring during the first half of 2020 arising, in part, from the public health crisis caused by the novel coronavirus known as COVID-19 and the resulting impact on fund performance. Ac-

cordingly, the Board reviewed, among other things, fund performance reflecting the more volatile periods, including for various time periods ended the first quarter of 2020 and for various time periods ended April 17, 2020. At the April Meeting, the Board Members asked questions and requested additional information that was provided for the May Meeting. In continuing its review of the Nuveen funds in light of the extraordinary market conditions experienced in early 2020, the Board received updated fund performance data reflecting various time periods ended May 8, 2020 for its May Meeting. The Board also continued its practice of seeking to meet periodically with the various sub-advisers to the Nuveen funds and their investment teams, when feasible.

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.

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 and its 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.

With respect to the Adviser, the Board recognized that the Adviser has provided a vast array of services the scope of which has expanded over the years in light of regulatory, market and other developments, such as the development of a liquidity management program and expanded compliance programs for the Nuveen funds. The Board also noted the extensive resources, tools and capabilities the Adviser and its affiliates devoted to the various operations of the Nuveen funds. These services include, but are not limited to: investment oversight, risk management and securities valuation services (such as analyzing investment performance and risk data; overseeing and reviewing the various sub-advisers to the Nuveen funds and their investment teams; overseeing trade execution, soft dollar practices and securities lending activities; providing daily valuation services and developing related valuation policies, procedures and methodologies; overseeing risk disclosure; periodic testing of investment and liquidity risks; participating in financial statement and marketing disclosures; participating in product development; and participating in leverage management and liquidity monitoring); product management (such as analyzing a fund’s position in the marketplace, setting dividends, preparing shareholder and intermediary communications and other due diligence support); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the funds’ independent public accountants and other service providers; managing fund budgets and expenses; and helping to fulfill the funds’ regulatory filing requirements); oversight of shareholder services and transfer agency functions (such as overseeing transfer agent service providers which include registered shareholder customer service and transaction processing; and overseeing proxy solicitation and tabulation services); 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 devising compliance programs; managing compliance policies; monitoring compliance with applicable fund policies and laws and regulations; and evaluating the compliance programs of the various sub-advisers to the Nuveen funds and certain other service providers); 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; and negotiating agreements with other fund service providers).

The Board also recognized that the Adviser and its affiliates have undertaken a number of initiatives over the previous year that benefited the complex and/or particular Nuveen funds including, but not limited to:

Table of Contents

•	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 enhance the shareholder outcomes through, among other things, rationalizing the product line and gaining efficiencies through mergers, repositionings and liquidations; launching new share classes; reviewing and updating investment policies and benchmarks; closing funds to new investments; rebranding the exchange-traded fund (“ETF”) product line; and integrating certain investment teams and changing the portfolio managers serving various funds;
•	Capital Initiatives – continuing to invest capital to support new Nuveen funds with initial capital as well as to facilitate modifications to the strategies or structure of existing funds;
•	Liquidity Management – implementing the liquidity risk management program which was designed to assess and manage the liquidity risk of the Nuveen funds. The Board noted that this program was particularly helpful in addressing the high volatility and liquidity challenges that arose in the market, particularly for the high yield municipal sector, during the first half of 2020;
•	Compliance Program Initiatives – continuing efforts to mitigate compliance risk, increase operating efficiencies, strengthen key compliance program elements and support international business growth and other objectives through, among other things, integrating various investment teams across affiliates, consolidating marketing review functions, enhancing compliance related technologies and establishing and maintaining shared broad-based compliance policies throughout the organization and its affiliates;
•	Risk Management and Valuation Services – continuing efforts to provide Nuveen with a more disciplined and consistent approach to identifying and mitigating the firm’s operational risks through, among other things, enhancing the interaction and reporting between the investment risk management team and various affiliates and adopting a risk operational framework across the complex;
•	Regulatory Matters – continuing efforts to monitor regulatory trends and advocate on behalf of 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 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 Services – continuing to periodically test business continuity and disaster recovery plans, 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
•	Expanded 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 investing resources to develop systems to assist in the process for newer products such as target term funds and ETFs.

The Board also 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. 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 Sub-Adviser’s assets under management and changes thereto, a summary of the applicable investment team and changes thereto, the investment approach of the team and the performance of the funds sub-advised by the Sub-Adviser over various periods. The Board further considered at the May Meeting or prior meetings evaluations of the Sub-Adviser’s compliance program 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 this regard, the Board reviewed, among other things, Fund performance over the quarter, one- and three- year periods ending December 31, 2019 (or for shorter periods available to the extent a Fund was not in existence during such periods). Unless otherwise indicated, the performance data referenced below reflects the periods ended December 31, 2019. In general, the year 2019 was a period of

Annual Investment Management Agreement Approval Process (continued)

strong market performance. However, as noted above, the Board recognized the unprecedented market volatility and decline that occurred in early 2020 and the significant impact it would have on fund performance. As a result, the Board reviewed performance data capturing more recent time periods, including performance data reflecting the first quarter of 2020 as well as performance data for various periods ended April 17, 2020 for its April Meeting and May 8, 2020 for its May Meeting. In addition, for funds that had changes in portfolio managers, the Board considered performance data 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.

As noted above, the Board reviewed fund performance over various periods ended December 31, 2019 as well as the first quarter of 2020 and various time periods ended April 17, 2020 and May 8, 2020. In light of the significant market decline in the early part of 2020, the Board noted that a shorter period of underperformance may significantly impact longer term performance. Further, the Board recognized that performance data may differ significantly depending on the ending date selected and accordingly, performance results for periods ended at the year-end of 2019 may vary significantly from performance results for periods ended in the first quarter of 2020, particularly given the extraordinary market conditions at that time as the impact of COVID-19 and other market developments unfolded. The Board considered a fund’s performance in light of the overall financial market conditions. In addition, 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.

With respect to Nuveen ETFs, the Board noted that the Nuveen ETFs, including the Funds, are designed to track the performance of a specified index (the “Underlying Index”). In its review, the Board received and reviewed, 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. Given each Fund’s investment objective of seeking investment results that correspond generally to the performance of its Underlying Index, however, the Board recognized that the extent to which a Fund tracked its benchmark was of greater relevance in assessing the performance for such Fund and therefore placed more emphasis on the tracking error and correlation data provided.

In addition to the performance data prepared in connection with the annual review of the advisory agreements of the Nuveen funds, the Board reviewed fund performance throughout the year at its quarterly meetings representing differing time periods and took into account the discussions that occurred at these Board meetings in evaluating a fund’s overall performance. The Board also considered, among other things, the Adviser’s analysis of each Nuveen fund’s performance, with particular focus on funds that were considered performance outliers (both overperformance and underperformance), the factors contributing to the performance and any steps taken to address any performance concerns. Given the volatile market conditions of early 2020, the Board considered the Adviser’s analysis of the impact of such conditions on the Nuveen funds’ performance.

The Board evaluated performance in light of various factors, including general market conditions, issuer-specific information, asset class information, fund cash flows and other factors. Accordingly, depending on the facts and circumstances, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below 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 efforts undertaken.

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

For the Enhanced Yield U.S. Aggregate Bond ETF, the Board considered, among other things, the Fund’s performance for the one- and three-year periods ended December 31, 2019, the performance of its Underlying Index for such periods, the correlation between the Fund’s performance and that of its Underlying Index, and the Fund’s tracking difference and excess return as compared to its Underlying Index. The Board further noted that the Fund ranked in the first quartile of its Performance Peer Group for the one-year period ended December 31, 2019 and second quartile of its Performance Peer Group for the three-year period ended December 31, 2019. With the market decline in the first quarter of 2020, the Board reviewed the performance of the Fund and its Underlying Index for the one- and three-year periods ended March 31, 2020 as well as the Fund’s tracking difference as compared to its Underlying Index. The Board noted that the Fund ranked in the second quartile of its Performance Peer Group for the one-year period ended March 31, 2020 and third quartile for the three-year period ended March 31, 2020. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. The Board was satisfied with the Fund’s overall performance.

For the Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF, the Board considered, among other things, the Fund’s performance for the one-year period ended December 31, 2019, the performance of its Underlying Index for such period, the correlation between the Fund’s performance and that of its Underlying Index, and the Fund’s tracking difference and excess return as compared to its Underlying Index. The Board further noted that the Fund ranked in the third quartile of its Performance Peer Group for the one-year period ended December 31, 2019. With the market decline in the first quarter of 2020, the Board reviewed the performance of the Fund and its Underlying Index for the one- and three-year periods ended March 31, 2020 as well as the Fund’s tracking difference as compared to its Underlying Index. The Board noted that the Fund ranked in the second quartile of its Perfor-

Table of Contents

mance Peer Group for the one-year period ended March 31, 2020 and first quartile for the three-year period ended March 31, 2020. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. The Board was satisfied with the Fund’s overall performance.

For the ESG U.S. Aggregate Bond ETF, the Board considered, among other things, the Fund’s performance for the one-year period ended December 31, 2019, the performance of its Underlying Index for such period, the correlation between the Fund’s performance and that of its Underlying Index, and the Fund’s tracking difference and excess return as compared to its Underlying Index. The Board further noted that the Fund ranked in the third quartile of its Performance Peer Group for the one-year period ended December 31, 2019. With the market decline in the first quarter of 2020, the Board reviewed the performance of the Fund and its Underlying Index for the one-year period ended March 31, 2020 as well as the Fund’s tracking difference as compared to its Underlying Index. The Board noted that the Fund ranked in the first quartile of its Performance Peer Group for the one-year period ended March 31, 2020. Given the Fund’s investment objective, however, the Board placed more emphasis on its review of the correlation and tracking difference data. The Board considered that the Fund was relatively new with a limited performance history available, limiting the ability to make a meaningful assessment of performance. Nevertheless, 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 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 the fund pays the Adviser 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 Nuveen fund with a net expense ratio of six basis points or higher compared to that of its peer average (each, an “Expense Outlier 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 each Fund pays the Adviser a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of such Fund, other than any distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, expenses incurred in acquiring and disposing of portfolio securities, fees and expenses of the Independent Board Members (including any of their counsel’s fees), certain expenses of such Fund’s chief compliance officer, litigation expenses and extraordinary expenses. 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, each Fund pays 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 noted 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 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 Board noted that each Fund had a net management fee and a net expense ratio that were below the respective peer averages.

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.

Annual Investment Management Agreement Approval Process (continued)

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. The Board also 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 considered, 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 complexity and myriad of services the Adviser had provided to the Nuveen funds compared to the other types of clients as the Adviser is principally responsible for all aspects of operating the funds, including complying with the increased regulatory requirements required when managing the funds 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 are 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 2019 and 2018. 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); revenues, expenses, and net income (pre-tax and after-tax and before distribution) of Nuveen for fund advisory services; and comparative profitability data comparing the margins of Nuveen compared to the adjusted margins of certain peers with 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. The Board also reviewed the revenues and expenses the Adviser derived from its ETF product line for the 2018 and 2019 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 expenses of Nuveen and its affiliates between the fund and non-fund businesses. The expenses to be allocated include direct expenses in servicing the Nuveen funds as well as indirect and/or shared costs (such as overhead, legal and compliance) some of which are attributed to the Nuveen funds pursuant to the cost allocation methodologies. The Independent Board Members reviewed a description of the cost allocation methodologies employed to develop the financial information and a summary of the history of changes to the methodology over the eleven-year period from 2008 to 2019. The Board had also appointed three Independent Board Members, along with the assistance of independent counsel, to serve as the Board’s liaisons 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. Based on the data, the Independent Board Members noted that Nuveen’s net margins were higher in 2019 than the previous year and considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between the years. The Board also noted the reinvestments of some of the profits into the business through, among other things, the investment of seed capital in certain funds and continued investments in enhancements to information technology, internal infrastructure and data management improvements and global investment and innovation projects.

As noted above, the Independent Board Members also considered Nuveen’s margins from its relationship to the Nuveen funds compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) to Nuveen for the calendar years 2019 and 2018. The Independent Board Members noted that Nuveen’s margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers. The Independent Board Members, however, recognized that it is difficult to make comparisons of profitability with other investment adviser peers given that comparative 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) which can have a significant impact on the results.

Table of Contents

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”). As such, the Board also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2019 and 2018 calendar years to consider the financial strength of TIAA. The Board recognized the benefit of having an investment adviser and its parent with significant resources, particularly during periods of market stress.

In addition to Nuveen, the Independent Board Members also considered the profitability of the Sub-Adviser from its relationships with the Nuveen funds. In this regard, the Independent Board Members reviewed, among other things, the Sub-Adviser’s revenues, expenses and net operating income for its advisory services to the Nuveen ETFs and closed-end funds for 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, 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. 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. In addition, given that the Nuveen ETFs were recently launched in 2016, the Independent Board Members recognized the Adviser’s costs in operating the Nuveen ETFs during the start-up phase.

The Independent Board Members also recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system and other systems and platforms that will, among other things, support growth, simplify and enhance information sharing, and enhance the investment process to the benefit of all of the Nuveen funds.

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, although the Board recognized that certain sub-advisers may be phasing out the use of soft dollars over time. The Board noted that the Sub-Adviser does not participate in soft dollar arrangements with respect to Fund portfolio transactions.

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.

PART II

Nuveen ESG High Yield Corporate Bond ETF

At the meeting held on September 19, 2019 (the “Meeting”), the Board Members, including the Independent Board Members, considered and approved the investment management agreement (for purposes of this Part II, the “Investment Management Agreement”) pursuant to which Nuveen Fund Advisors, LLC (the “Adviser”) serves as the investment adviser to Nuveen ESG High Yield Corporate Bond ETF (for purposes of this Part II, the “Fund”), a series of Nushares ETF Trust (the “Trust”), and the investment sub-advisory agreement (for purposes of this Part II, the “Sub-Advisory Agreement”) with Teachers Advisors, LLC (the “Sub-Adviser”) pursuant to which the Sub-Adviser serves as the investment sub-adviser to the Fund. For purposes of this Part II, (a) the Adviser and the Sub-Adviser are each hereafter a “Fund Adviser” and (b) the Investment Management Agreement and the Sub-Advisory Agreement are each hereafter an “Advisory Agreement” and collectively, the “Advisory Agreements.”

To assist the Board in its evaluation of an Advisory Agreement with a Fund Adviser at the Meeting, the Independent Board Members had received, in adequate time in advance of the Meeting or at prior meetings, materials which outlined, among other things:

•	the nature, extent and quality of the services expected to be provided by the Fund Adviser;
•	the organization of the Fund Adviser, including the responsibilities of various departments and key personnel;
•	the relevant expertise and background of the Fund Adviser with respect to the Fund’s investment strategy;
•	certain performance-related information (as described below);
•	certain profitability-related information (as described below);
•	the Fund’s proposed unitary fee structure, including comparisons of the Fund’s proposed net expense ratio with the net expense ratios of comparable funds; and
•	the soft dollar practices of the Fund Adviser, if any.

At the Meeting and/or at prior meetings, the Adviser made presentations to and responded to questions from the Board. During the Meeting and/or at prior meetings, the Independent Board Members also met privately with their legal counsel to, among other things, review the Board’s duties under the 1940 Act, the general principles of state law in reviewing and approving advisory contracts, the standards used by courts in determining whether investment company boards of directors have fulfilled their duties, factors to be considered in voting on advisory contracts and an adviser’s fiduciary duty with respect to advisory agreements and compensation. It is with this background that the Independent Board Members considered the Advisory Agreements. As outlined in more detail below, the Independent Board Members considered various factors they believed relevant with respect to the Fund. Each Board Member may have accorded different weight to the various factors and information discussed below in reaching his or her conclusions with respect to the Fund’s Advisory Agreements. The Board Members also drew on information they had received in their capacity as trustees and directors, as applicable, of other registered investment companies advised by the Fund Advisers.

A. Nature, Extent and Quality of Services

The Independent Board Members considered the nature, extent and quality of the respective Fund Adviser’s services, including portfolio management services and administrative services. Given that the Adviser and the Sub-Adviser already serve as adviser and sub-adviser, respectively, to other Nuveen funds overseen by the Board Members, the Board has a good understanding of each such Fund Adviser’s organization, operations, personnel and services. As the Independent Board Members meet regularly throughout the year to oversee the Nuveen funds, including funds currently advised by the Fund Advisers, the Independent Board Members, have, in part, relied upon their knowledge from their meetings and any other interactions throughout the year with the respective Fund Adviser in evaluating the Advisory Agreements.

The Independent Board Members recognized that open-end exchange-traded funds (“ETFs”) were a relatively recent addition to the Nuveen fund product line (i.e., added in 2016). They considered information about the structure, investment objective, investment strategy and other characteristics of the Fund. Additionally, they observed that the Fund was expected to seek to track the investment results of a specified underlying index (the “Index”).

Table of Contents

The Board noted that the Fund would be a registered investment company that would operate in a regulated industry. In considering the services that were expected to be provided by the Fund Advisers, at the Meeting and/or at prior meetings, the Board has recognized that the Adviser provides a comprehensive set of services necessary to operate the Nuveen funds in a highly regulated industry and has noted that the scope of such services has expanded over the years as a result of regulatory, market and other developments, such as the development of the liquidity management program and expanded compliance programs. Some of the functions the Adviser is responsible for include, but are not limited to: product management (such as analyzing a fund’s position in the marketplace, setting dividends, preparing shareholder and intermediary communications and other due diligence support); investment oversight (such as analyzing fund performance, sub-advisers and investment teams and analyzing trade executions of portfolio transactions, soft dollar practices and securities lending activities); securities valuation services (such as executing the daily valuation process for portfolio securities and developing and recommending changes to valuation policies and procedures); risk management (such as overseeing operational and investment risks, including stress testing); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the Nuveen funds’ independent public accountants and other service providers; managing fund budgets and expenses; and helping to fulfill the funds’ regulatory filing requirements); oversight of shareholder services and transfer agency functions (such as oversight and liaison of transfer agent service providers which include registered shareholder customer service and transaction processing); 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 developing and maintaining a compliance program to ensure compliance with applicable laws and regulations, monitoring compliance with applicable fund policies and procedures and adherence to investment restrictions, and evaluating the compliance programs of the Nuveen fund sub-advisers and certain other service providers); and legal support and oversight of outside law firms (such as with respect to filing and updating registration statements; maintaining various regulatory registrations; and providing legal interpretations regarding fund activities, applicable regulations and implementation of policies and procedures). The Board was aware, however, that services provided to ETFs may in some respects differ from those provided to other Nuveen funds. The Independent Board Members noted that the Adviser would oversee the Sub-Adviser, which was generally expected to provide portfolio advisory services to the Fund. In addition, the Independent Board Members recognized the relevant experience and expertise of the investment team expected to manage the Fund. In this regard, they noted that the portfolio managers that were expected to serve the Fund also serve as portfolio managers to certain other Nuveen ETFs.

Based on their review, the Independent Board Members found that, overall, the nature, extent and quality of services expected to be provided to the Fund under each Advisory Agreement were satisfactory.

B. Investment Performance

The Fund was new and, therefore, did not have its own performance history. The Independent Board Members, however, were familiar with the performance records of other Nuveen funds advised by the Adviser and noted that the Sub-Adviser manages other Nuveen ETFs. In addition, the Independent Board Members reviewed certain historical performance-related data pertaining to the Index as well as the Fund’s contemplated secondary index (including (i) returns for the 1- year, 2- year annualized, 3- year annualized and since inception (i.e., beginning June 30, 2015) annualized periods as of December 31, 2018 and (ii) calendar year returns for 2016 through 2018).

C. Fees, Expenses and Profitability

1. Fees and Expenses

In evaluating the management fees and expenses that the Fund was expected to bear, the Independent Board Members considered, among other things, the Fund’s proposed unitary fee structure and its proposed net expense ratio in absolute terms as well as compared with the net expense ratios of comparable ETFs.

In considering the Fund’s proposed unitary fee structure, the Independent Board Members took into account the Adviser’s representation that unitary fee structures were generally common for ETFs. They noted that under this structure, the Fund would pay a fee to the Adviser and, in turn, the Adviser would be generally responsible for the fees incurred by the Fund (such as custody fees, transfer agency fees, index licensing fees, and stock exchange listing fees, as well as the fee paid to the Sub -Adviser), subject to certain exceptions (which included the management fee, any payments under the Trust’s distribution and service plan, interest expenses, taxes, acquired fund fees and expenses, expenses incurred in acquiring and disposing of portfolio securities, certain compensation expenses of the Fund’s chief compliance officer, fees and expenses of the Independent Board Members and their counsel, litigation expenses and extraordinary expenses). In this regard, the Independent Board Members were provided with estimates of the Fund’s anticipated expenses, including those that would be paid by the Adviser from the unitary fee and those that would be excluded from the unitary fee, to the extent available.

In addition, in considering the proposed unitary fee structure, the Independent Board Members took into account that the Adviser would generally bear the risk that certain of the Fund’s operating expenses would increase (but would also benefit if such expenses decrease) and the degree of expense stability that would be afforded to the Fund’s shareholders. Additionally, the Independent Board Members reviewed, among other things, the Fund’s proposed unitary fee as well as comparative data pertaining to unitary fees of the ETFs included in peer groups comprised of the ten most recently launched high yield bond ETFs (the “Recently Launched ETFs Peer Group”) and the ten largest high yield bond ETFs (the “Largest ETFs Peer Group”). The Independent Board Members noted that (a) as compared to the Recently Launched ETFs Peer Group, the proposed unitary

Table of Contents

Annual Investment Management Agreement Approval Process (continued)

fee to be charged to the Fund was equal to the median fee and the average fee, and below the weighted average fee and (b) as compared to the Largest ETFs Peer Group, the proposed unitary fee to be charged to the Fund was below the median fee, average fee and weighted average fee. Further, the Independent Board Members considered the proposed sub-advisory fee for the Fund, which, as noted above, will be paid by the Adviser out of its unitary fee.

Based on their review of the fee and expense information provided, the Independent Board Members determined that the Fund’s unitary fee was reasonable in light of the nature, extent and quality of services to be provided to the Fund.

2. Comparisons with the Fees of Other Clients

The Board considered that the Fund will pay a unitary fee, which will differ from most other investment companies advised by the Adviser which pay a variety of fees, such as the investment advisory fee; Rule 12b-1 fees, if any; transfer agency fees; custody fees; and other expenses. The Board believed the unitary fee structure provides certain benefits to shareholders as it clearly discloses the cost of owning Fund shares, provides a level of cost certainty by shifting to the Adviser the risk that some of the costs of operating the Fund may rise, and provides an incentive to the Adviser to maximize administrative efficiencies. As noted, the Board considered the unitary fee to be paid by the Fund in comparison to the unitary fees of the ETFs included in the Recently Launched ETFs Peer Group and the Largest ETFs Peer Group.

The Board has also noted at prior meetings that the Adviser and/or the Sub-Adviser provide services to other types of clients, which may include foreign investment companies offered by Nuveen, certain funds advised by the Sub-Adviser and other ETFs sponsored by Nuveen. In this regard, the Board has previously reviewed, among other things, the range of fees assessed for foreign investment companies and ETFs offered by Nuveen and the management fees and expense ratios of certain funds advised by the Sub-Adviser in the TIAA-CREF family of funds. In addition to the comparative fee data, the Board has also reviewed, among other things, a description of the different levels of services provided to certain other clients compared to the services provided to the Nuveen funds as well as the differences in portfolio investment policies, investor profiles, account sizes and regulatory requirements, all of which contribute to the variations in fee schedules. The Board has also noted, among other things, the wide range of services in addition to investment management services provided to the Nuveen funds when the Adviser is principally responsible for all aspects of operating the funds, including the increased regulatory requirements that must be met in managing the funds and the increased entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the funds. The Board has also considered that the Nuveen ETFs are passively managed compared to the active management of the other Nuveen funds, which has contributed to the differences in fee levels between Nuveen ETFs and other Nuveen funds. In general, the Board has noted that the 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 has further considered that the Sub-Adviser’s fee is essentially for portfolio management services. The Board has concluded that varying levels of fees are 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

At the time of the Meeting, historical information regarding the costs of services provided by the Adviser to the Fund and the profitability of the Fund to the Adviser was not available as the Fund had not commenced operations and it was not possible to predict the effect on profitability of the Fund. The Independent Board Members, however, considered the estimated operating expenses to be paid by the Adviser pursuant to the unitary fee.

Further, at prior meetings, conjunction with their review of fees, the Independent Board Members have considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2018 and 2017. In this regard, the Board has 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); revenues, expenses, and net income (pre-tax and after-tax and before distribution) of Nuveen for fund advisory services; and comparative profitability data comparing the adjusted margins of Nuveen compared to the adjusted margins of certain peers with 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. The Board has also reviewed the revenues and expenses the Adviser derived from its ETF product line that was launched in 2016. The Independent Board Members have noted that Nuveen’s net margins were higher in 2018 than the previous year and have considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between the years. The Board has considered the costs of investments in the Nuveen business, including the investment of seed capital in certain Nuveen funds and additional investments in infrastructure and technology. The Independent Board Members have also noted that Nuveen’s adjusted margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers; however, the Independent Board Members have recognized the inherent limitations of the comparative data of other publicly traded peers given that the calculation of profitability is rather subjective and numerous factors (such as types of funds, business mix, cost of capital, methodology to allocate expenses and other factors) can have a significant impact on the results.

Table of Contents

The Independent Board Members have also reviewed a description of the expense allocation methodology employed to develop the financial information and a summary of the history of changes to the methodology over the ten-year period from 2008 to 2018, and have recognized that other reasonable allocation methodologies could be employed and lead to significantly different results. The Board has noted that two Independent Board Members, along with independent counsel, serve as the Board’s liaisons to review profitability and discuss any proposed changes to the methodology prior to the full Board’s review.

Aside from Nuveen’s profitability, the Board has recognized that the Adviser is a subsidiary of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). As such, the Board has also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2018 and 2017 calendar years to consider the financial strength of TIAA having recognized the importance of having an adviser with significant resources.

In evaluating the reasonableness of the compensation, the Independent Board Members have 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 has noted that Nuveen’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

With respect to economies of scale, the Independent Board Members have recognized that, in general, as the assets of a particular fund or the Nuveen complex in the aggregate increase over time, economies of scale may be realized with respect to the management of the funds. In this regard, the Independent Board Members considered whether economies of scale were expected to be achieved as the Fund grows and whether any such economies of scale were expected to be shared with shareholders. Although the Independent Board Members have recognized that economies of scale are difficult to measure, they have noted that the Adviser shares the benefits of economies of scale in various ways, including through breakpoints in the management fee schedules (subject to limited exceptions), fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in its business which can enhance the services provided to the Nuveen funds for the fees paid. Most of the funds in the Nuveen complex pay a management fee to the Adviser which is generally comprised of a fund-level component and a complex- level component, each of which has a breakpoint schedule. Generally, the fund level fee component declines as the assets of a particular fund grow. Pursuant to the complex-wide fee arrangement, generally, the complex- level fee component declines when eligible assets of the funds in the Nuveen complex combined grow.

Notwithstanding the foregoing, the Independent Board Members recognized that the unitary fee structure does not have breakpoints and that the Fund (like other Nuveen ETFs) would not participate in the complex-level fee program. However, the Independent Board Members acknowledged, at the Meeting and/or at prior meetings, that as ETFs were relatively new to the Nuveen fund family, there would be ongoing review with respect to the fee structure employed for these types of funds. They have further recognized that although a unitary fee provides shareholders with a level of certainty with respect to the expenses of a Nuveen ETF, the Adviser will benefit from any reductions in certain fixed costs associated with managing the Nuveen ETF (although the Adviser also has the risk if such fixed costs rise).

In addition, at the Meeting and/or at prior meetings, the Independent Board Members have recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system as well as other systems and platforms that will, among other things, support growth, simplify and enhance information sharing, and enhance the investment process to the benefit of all of the Nuveen funds.

Based on their review, the Independent Board Members concluded that the proposed unitary fee structure (which would not include breakpoints or participation in the complex-level fee program) was acceptable.

E. Indirect Benefits

The Independent Board Members considered information received at the Meeting and/or at prior meetings regarding other benefits that a Fund Adviser or its affiliates may receive as a result of their relationship with the Nuveen funds. The Independent Board Members have considered whether the Sub-Adviser may engage in soft dollar transactions pursuant to which it may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds. The Board noted that the Sub-Adviser does not participate in soft dollar arrangements with respect to Nuveen fund portfolio transactions.

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

F. Approval

The Independent Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including a majority of the Independent Board Members, concluded that the terms of the Investment Management Agreement and the Sub-Advisory Agreement were fair and reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services to be provided to the Fund and that the Investment Management Agreement and Sub-Advisory Agreement should be and were approved on behalf of the Fund.

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 (the “Funds”) has adopted and implemented a liquidity risk management program (the “Program”), which is designed to manage the Fund’s liquidity risk. The Program consists of various protocols for assessing and managing each Fund’s liquidity risk. The Funds’ Board of Trustees previously designated Nuveen Fund Advisors, LLC, the Funds’ investment 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 (the LOSC”). The LOSC is composed of personnel from the adviser and Teachers Advisors, LLC, an affiliate of the adviser.

At a May 20, 2020 meeting of the Board, the Administrator provided the Board with a written report addressing the Program’s operation, adequacy and effectiveness of implementation for calendar year 2019 (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, the 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 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 Fund portfolio investment is classified into one of four liquidity categories (including the most liquid, “Highly Liquid”, and the least liquid, “Illiquid”, 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, and use third-party vendor data.

Any Fund that does not primarily hold highly liquid investments must, among other things, determine a minimum percentage of Fund 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 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, no Fund exceeded the 15% limit on Illiquid investments.

Trustees and Officers

(Unaudited)

The management of the Funds, including general supervision of the duties performed for the Funds by the Adviser, is the responsibility of the Board of Trustees of the Funds. None of the Trustees who are not “interested” persons of the Funds (referred to herein as “Independent Trustees”) has ever been a Trustee or employee of, or consultant to, Nuveen or its affiliates. The names and business addresses of the Trustees and officers of the Funds, their principal occupations and other affiliations during the past five years, the number of portfolios each Trustee oversees and other directorships they hold are set forth below.
