Chair’s Letter to Shareholders    
Dear Shareholders,
The COVID-19 crisis is taking an unprecedented toll on our health, societies, economies and financial markets. The extreme “social distancing” efforts needed to contain the coronavirus are causing a severe contraction in economic activity and amplifying market volatility, as global supply chains and consumer and business demand remain significantly disrupted. However, the full economic impact remains to be seen. The number of confirmed cases is still accelerating in the U.S. and many parts of the world, and previous epidemics offer few parallels to today’s situation. The recent spike in market volatility reflects this uncertainty, and we expect that large swings in both directions are likely to continue until there is more clarity.
While we do not want to understate the dampening effect on the global economy, we also note that markets occasionally overreact. Differentiating short-term interruptions from the longer-lasting implications to the economy may provide opportunities. Some areas of the global economy were already on the mend prior to the coronavirus epidemic. Momentum could pick up again as factories come back online and consumer demand resumes once the virus is under control and temporary bans on movement and travel are lifted. Central banks and governments around the world have announced economic stimulus measures. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and reintroduced programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. government has approved more than $100 billion in emergency spending and relief and is set to deliver a trillion-dollar package to further aid workers and businesses.
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 advisor, 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
March 24, 2020

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 key investment strategies and the six-month performance of the Funds.
Nuveen Enhanced Yield U.S. Aggregate Bond ETF (NUAG)
What key strategies were used to manage the Fund during the six-month reporting period and how did these strategies influence performance?
The Fund employs a passive management (or “indexing”) approach, seeking to track the investment results, before fees and expenses, of the ICE BofA Enhanced Yield U.S. Broad Bond Index (the “NUAG Enhanced Index”). The NUAG Enhanced Index is designed to broadly capture the U.S. investment grade fixed income market and uses a rules-based weighting methodology that seeks to enhance yield while maintaining comparable risk. The NUAG Enhanced Index is primarily comprised of U.S. government securities, debt securities issued by U.S. corporations, residential and commercial mortgage-backed securities, asset-backed securities and U.S. dollar-denominated debt securities issued by non-U.S. corporations that are publicly offered for sale in the U.S. The 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 January 31, 2020, the Fund’s net assets were invested in 36.2% securitized debt, 34.7% corporate debt, 23.1% U.S. Treasuries and 20.8% government-related debt.
How did the Fund perform during the six-month reporting period ended January 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 six-month, one-year and since inception periods ended January 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.
This material is not intended to be a recommendation or investment advice, does not constitute a solicitation to buy, sell or hold a security or an investment strategy, and is not provided in a fiduciary capacity. The information provided does not take into account the specific objectives or circumstances of any particular investor, or suggest any specific course of action. Investment decisions should be made based on an investor’s objectives and circumstances and in consultation with his or her advisors.
Certain statements in this report are forward-looking statements. Discussions of specific investments are for illustration only and are not intended as recommendations of individual investments. The forward-looking statements and other views expressed herein are those of the portfolio managers as of the date of this report. Actual future results or occurrences may differ significantly from those anticipated in any forward-looking statements and the views expressed herein are subject to change at any time, due to numerous market and other factors. The Funds disclaim any obligation to update publicly or revise any forward-looking statements or views expressed herein.
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.

Portfolio Managers’ Comments (continued)
The Fund’s total return underperformed the NUAG Enhanced Index during the reporting period. The relative underperformance is mainly attributable to the transaction costs related to the Fund’s acquisition of portfolio securities, the fees and expenses incurred by the Fund that are not incurred by the NUAG Enhanced Index, and 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 and underweight (and, in some cases, not invested at all in) certain securities as compared to the Index. The NUAG Enhanced Index is unmanaged and therefore its returns do not reflect any fees or expenses, which would detract from its performance. You cannot invest directly in an index.
U.S. fixed income markets produced positive returns over the reporting period. The Federal Reserve lowered its benchmark interest rate three times in the second half of 2019 to help extend the economic cycle in the face of growing downside risks from trade tensions and weaker growth abroad. Geopolitical events including escalating tariff rhetoric, a U.S.-Iran military conflict and the COVID-19 coronavirus epidemic triggered bouts of risk aversion. However, optimism for a U.S.-China trade deal and improving macroeconomic indicators periodically swung sentiment in the other direction. Amid elevated interest rate volatility, the 10-year U.S. Treasury yield fell to 1.51% as of January 31, 2020 from 2.02% as of July 31, 2019. Longer maturity bonds generally outperformed shorter dated bonds, while performance across government and non-government sectors was broadly positive. Corporate bond credit spreads tightened amid a moderately healthy U.S. economy, strong stock market and robust investor demand for higher yielding assets. Securitized assets were well supported by favorable outlooks for consumer credit and the housing and mortgage markets, although falling interest rates prompted concerns about mortgage prepayments accelerating.
Nuveen Enhanced Yield 1-5 Year U.S. Aggregate Bond ETF (NUSA)
What key strategies were used to manage the Fund during the six-month reporting period and how did these strategies influence performance?
The Fund employs a passive management (or “indexing”) approach, seeking to track the investment results, before fees and expenses, of the ICE BofA Enhanced Yield 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 January 31, 2020, the Fund’s net assets were invested in 47.0% corporate debt, 26.9% securitized debt, 26.2% U.S. Treasuries, and 0.8% 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 January 31, 2020, the Fund’s net assets were invested in the following corporate bond sectors: 87.9% industrials, 7.2% financial institutions and 2.9% utilities and 0.8% government-related debt.
How did the Fund perform during the abbreviated reporting period ended January 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 January 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 reporting period. The 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.
High yield corporate bonds delivered positive performance during the abbreviated reporting period. Investor sentiment improved as the U.S. and China agreed to a preliminary trade deal, which was signed in January 2020, and recession risks appeared to diminish with sustained moderate growth in the U.S. and stabilization in some economic indicators abroad. The optimistic tone continued to

support demand for high yield bonds, despite a modest increase in default activity in 2019, particularly in commodity-related sectors. As the reporting period closed, however, high yield credit spreads widened, equity markets sold off and commodity prices fell amid concern about the COVID-19 coronavirus outbreak and its dampening effect on global economic activity.
Nuveen ESG U.S. Aggregate Bond ETF (NUBD)
What key strategies were used to manage the Fund during the six-month reporting period and how did these strategies influence performance?
The Fund employs a passive management (or “indexing”) approach, 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”). The NUBD Select 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. corporations that are publicly offered for sale in the U.S. The NUBD Select Index selects from the securities included in the Bloomberg Barclays U.S. Aggregate Bond Index (the “Base Index”), which is designed to broadly capture the U.S. investment grade, taxable fixed income 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 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 January 31, 2020, the Fund’s net assets were invested in 38.7% U.S. Treasuries, 28.9% securitized debt, 25.2% corporate debt and 13.7% government-related debt.

An Update on COVID-19 Coronavirus
The COVID-19 coronavirus pandemic has delivered an exogenous shock to the global economy. Containment efforts around the world have halted business and manufacturing operations and restricted people’s movement and travel. The disruptions to global supply chains, consumer demand, business investment and the global financial system are just beginning to be seen.
Although the virus was detected in China as early as December 2019, markets didn’t fully acknowledge the risks until February 2020, when large outbreaks were reported outside of China. Global stock markets sold off severely, reaching a bear market (a 20% drop from the previous high) within three weeks, the fastest bear market decline in history. Demand for safe-haven assets, along with mounting recession fears, drove the yield on the 10-year U.S. Treasury note below 1% in March, an all-time low. Additionally, oil prices collapsed to an 18-year low in March on supply glut concerns, as shutdowns across the global economy curb oil demand while Saudi Arabia and Russia are flooding the market with cheap oil in a price war.
Central banks and governments have responded with liquidity injections to ease the strain on financial systems and stimulus measures to buffer the shock to businesses and consumers. But markets will likely remain volatile until the health crisis itself is under control (via fewer new cases, slower spread and/or verified treatments). There are still many unknowns and new information is incoming daily, compounding the difficulty of modeling outcomes for epidemiologists and economists alike.
Nuveen is monitoring the situation carefully and continuously refining our views. Our portfolio management teams remain attuned to opportunities to seek risk-adjusted returns through all market environments.

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.

Yields    as of January 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 January 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. Since NUHY’s expense example below reflects only the first 129 days of the Fund’s operations, it may not provide a meaningful understanding of the Fund’s ongoing expenses.
The Examples below are based on an investment of $1,000 invested at the beginning of the period and held through the period ended January 31, 2020.
The beginning of the period for NUAG, NUSA and NUBD is August 1, 2019 and NUHY is September 25, 2019 (commencement of operations).
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.  
(3) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns.

  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.

  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.  
(3) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns.

Notes to Financial Statements    
(Unaudited)
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 January 31, 2020, and the period covered by these Notes to Financial Statements for NUAG, NUSA and NUBD is the six months ended January 31, 2020 and for NUHY is September 25, 2019 (commencement of operations) through January 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.
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 Board has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.
Distributions to Shareholders
Distributions to shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.
Indemnifications
Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Trust enters into contracts that provide general indemnifications to other parties. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
Investments and Investment Income
Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. 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 Accounting Standards Update ("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.
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.
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.

4.  Portfolio Securities and Investments in Derivatives
Portfolio Securities
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.
60
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 $126,725,056 $5,610,286 $11,506,513 $27,681,939
U.S. Government and agency obligations 23,369,674 1,511,250  — 16,517,134
Sales and maturities:        
Investment securities 85,799,251 3,942,095 7,185,092 4,157,152
U.S. Government and agency obligations 14,822,393 603,586  — 1,420,762
In-kind transactions during the current fiscal period were as follows:
  NUAG NUSA NUHY NUBD
In-kind purchases $138,233,325 $ — $47,512,951 $  —
In-kind sales 103,915,917  —  — 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.
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.

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 January 31, 2020.
  NUAG NUSA NUHY NUBD
Tax cost of investments $177,244,981 $29,800,206 $52,276,630 $96,765,499
Gross unrealized:        
Appreciation $ 1,720,134 $ 661,880 $ 314,387 $ 2,980,634
Depreciation (81,079) (34,214) (418,176) (37,817)
Net unrealized appreciation (depreciation) of investments $ 1,639,055 $ 627,666 $ (103,789) $ 2,942,817
Permanent differences, primarily due to redemption in-kind, bond premium amortization adjustments, taxes paid, and paydowns resulted in reclassifications among the Funds' components of net assets as of July 31, 2019, the Funds' last tax year end.
The tax components of undistributed net ordinary income and net long-term capital gains as of July 31, 2019, the Funds' last tax year end, were as follows:
  NUAG NUSA NUBD
Undistributed net ordinary income1 $232,791 $87,713 $167,112
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' last tax year ended July 31, 2019 was designated for purposes of the dividends paid deduction as follows:
  NUAG NUSA NUBD
Distributions from net ordinary income1 $3,510,400 $855,950 $1,392,050
Distributions from 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.
As of July 31, 2019, the Funds’ last 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 NUBD
Not subject to expiration:      
Short-term $  — $ 71,352 $ 88,928
Long-term 1,259,805 203,512 86,570
Total $1,259,805 $274,864 $175,498
During the Funds' last tax year ended July 31, 2019, NUAG utilized $1,391,402 of its capital loss carryforward.
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
NUHY 0.35
NUBD 0.20
Other Transactions with Affiliates
As of the end of the reporting period, Nuveen owned shares of the following Fund as follows:

8.  Subsequent Event
Other Matters
The COVID-19 coronavirus pandemic was first detected in China in December 2019 and subsequently spread internationally. Containment efforts around the world have halted business and manufacturing operations and restricted people’s movement and travel. The disruptions to global supply chains, consumer demand, business investment and the global financial system are just beginning to be seen. The impact of the coronavirus may last for an extended period of time and through the date these financial statements are issued, has resulted in substantial market volatility and may result in a significant economic downturn.

Glossary of Terms Used in this Report    
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.

Annual Investment Management Agreement Approval Process    
The 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 21-23, 2019 (the “May Meeting”), the Board, including the 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 such 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 sub-adviser to such Fund. Following an initial two-year period, the Board, including the Independent Board Members, is required under the 1940 Act to review and approve 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.”
In response to a request on behalf of the Independent Board Members by independent legal counsel, the Board received and reviewed prior to the May Meeting extensive materials specifically prepared for the annual review of Advisory Agreements by the Adviser as well as by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials provided in connection with the annual review covered a breadth of subject matter including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of the Sub-Adviser and investment team; 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 of Nuveen; and a description of indirect benefits received by the Fund Advisers as a result of their relationships with the Nuveen funds. The Board Members held an in-person meeting on April 17-18, 2019 (the “April Meeting”), in part, to review and discuss the performance of the Nuveen funds and the Adviser’s evaluation of the various sub-advisers to the Nuveen funds. The Independent Board Members asked questions and requested additional information that was provided for the May Meeting.
The information prepared specifically for the annual review of the Advisory Agreements supplemented the information provided to the Board and its committees throughout the year. The Board and its committees met regularly during the year and the information provided and topics discussed were relevant to the review of the Advisory Agreements. Some of these reports and other data included, among other things, materials that outlined the investment performance of the Nuveen funds; strategic plans of the Adviser which may impact the services it provides to the Nuveen funds; the review of the Nuveen funds and applicable investment teams; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers; valuation of securities; fund expenses; and overall market and regulatory developments. The Board further 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 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 Fund 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.
67
Annual Investment Management Agreement Approval Process (continued)
The Independent Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives from the Adviser or the Sub-Adviser were present. In connection with their annual review, the Independent Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements.
In deciding to renew the Advisory Agreements, the Independent Board Members did not identify a particular factor or information as determinative or controlling, but rather the decision reflected the comprehensive consideration of all the information provided, 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 Board recognized that the Adviser provides a comprehensive set of services necessary to operate the Nuveen funds in a highly regulated industry and 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). In reviewing the scope and quality of services, the Board recognized the continued efforts and resources the Adviser and its affiliates have employed to continue to enhance their services for the benefit of the complex as well as particular Nuveen funds over recent years. Such service enhancements have included, but are not limited to:
• 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, repositioning funds, merging funds, reviewing and updating investment policies and benchmarks, modifying the composition of certain portfolio management teams and analyzing various data to help devise such improvements;
• Capital Initiatives  –  continuing to invest capital to support new funds with initial capital as well as to facilitate modifications to the strategies or structure of existing funds;
• Compliance Program Initiatives  –  continuing efforts to enhance the compliance program through, among other things, internally integrating various portfolio management teams and aligning compliance support accordingly, completing a comprehensive review of existing policies and procedures and revising such policies and procedures as appropriate, enhancing compliance-related technologies and workflows, and optimizing compliance shared services across the organization and affiliates;
• Risk Management and Valuation Services  –  continuing efforts to strengthen the risk management functions, including through, among other things, enhancing the interaction and reporting between the investment risk management team and various affiliates, increasing the efficiency of risk monitoring performed on the Nuveen funds through improved reporting, continuing to implement risk programs designed to provide a more disciplined and consistent approach to identifying and mitigating operational risks, continuing progress on implementing a liquidity program that complies with the new liquidity regulatory requirements and continuing to oversee the daily valuation process;
• Additional Compliance Services  –  continuing investment of time and resources necessary to develop the compliance policies and procedures and other related tools necessary to meet the various new regulatory requirements affecting the Nuveen funds that have been adopted over recent years;
68
• Government Relations  –  continuing efforts of various Nuveen teams and affiliates to advocate and communicate their positions with lawmakers and other regulatory bodies on issues that will impact the Nuveen funds;
• Business Continuity, Disaster Recovery and Information Services  –  establishing an information security program to help identify and manage information security risks, periodically testing disaster recovery plans, maintaining and updating business continuity plans and providing reports to the Board, at least annually, addressing, among other things, management’s security risk assessment, cyber risk profile, incident tracking and other relevant information technology risk-related reports; and
• Expanded Dividend Management Services  –  continuing to expand the services necessary to manage the dividends among the varying types of Nuveen funds that have developed as the Nuveen complex has grown in size and scope.
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. The Board noted that the Adviser oversees the Sub-Adviser and 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 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 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 the investment performance of the Nuveen funds they advise. In this regard, the Board reviewed Fund performance over the quarter and one-year periods ending December 31, 2018 as well as performance data for the first quarter of 2019 ending March 29, 2019. Unless otherwise indicated, the performance data referenced below reflects the periods ended December 31, 2018. The Board considered the Adviser’s analysis of each fund’s performance, with particular focus on funds that were considered performance outliers and the factors contributing to their performance. The Board also noted that it received performance data of the Nuveen funds during its quarterly meetings throughout the year and took into account the discussions that occurred at these Board meetings regarding fund performance. In this regard, in its evaluation of Nuveen fund performance at meetings throughout the year, the Board considered performance information for the funds for different time periods, both absolute and relative to appropriate benchmarks and peers, with particular attention to information indicating underperformance of the respective funds and discussed with the Adviser the reasons for such underperformance.
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 funds compared to certain peer groups and/or benchmark(s) will necessarily contribute to differences in performance results and limit the value of the comparative information. In addition, the performance data may vary significantly depending on the end date selected, and shareholders may evaluate fund performance based on their own holding period which may differ from the performance periods reviewed by the Board leading to different results. Further, the Board considered a fund’s performance in light of the overall financial market conditions during the respective periods. As noted above, the Board reviewed, among other things, Nuveen fund performance over various periods ended December 31, 2018, and the Board was aware of the market decline in the fourth quarter of 2018 and considered performance from the first quarter of 2019 as well. The Board also noted that a shorter period of underperformance may significantly impact longer term performance.
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, with respect to each Fund, the Board received and reviewed, among other things, the net asset value performance of the Fund, the performance of the Fund’s Underlying Index and parent index, its relative performance compared to the performance of peer funds (the “Performance Peer Group”) and the 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 their review of performance, the Independent Board Members focused, in particular, on the Adviser’s analysis of Nuveen funds determined to be underperforming performance outliers. The Board recognized that some periods of underperformance may only be temporary while other periods of underperformance may indicate a broader issue that may require a corrective action. Accordingly, 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.
69
Annual Investment Management Agreement Approval Process (continued)
For the Enhanced Yield U.S. Aggregate Bond ETF, the Board considered, among other things, the Fund’s performance for the one-year period ended December 31, 2018, 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 but given the Fund’s investment objective, 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 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, 2018, 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 second quartile of its Performance Peer Group for the one-year period but given the Fund’s investment objective, 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 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, 2018, 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 first quartile of its Performance Peer Group for the one-year period but given the Fund’s investment objective, 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 performance.
C. Fees, Expenses and Profitability
1. Fees and Expenses
In its annual review, the Board considered the fees paid to the Fund Advisers and the total operating expense ratio of each Nuveen fund. More specifically, the Board recognized that each Fund pays the Adviser a unitary fee and therefore, the Board reviewed each Fund’s 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.
With respect to the Sub-Adviser, the Board considered the sub-advisory fee paid to the Sub-Adviser, and as described below, comparative data of the fees the Sub-Adviser charges to other clients, if any.
As indicated 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 each 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.
The Independent Board Members noted that each Fund had a net management fee and a net expense ratio that were in line with the average of its Peer Group.
70
Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.
2. Comparisons with the Fees of Other Clients
In determining the appropriateness of fees, the Board also reviewed 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, certain funds advised by the Sub-Adviser and other ETFs sponsored by Nuveen.
In this regard, the Board 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 addition to the comparative fee data, the Board 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 the fee schedules. The Board 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 also considered that the Nuveen ETFs are passively managed compared to the active management of the other Nuveen funds which contributed to the differences in fee levels between 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 conjunction with their review of fees, the Independent Board Members considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2018 and 2017. 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 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 also reviewed the revenues and expenses the Adviser derived from its ETF product line that was launched in 2016. The Independent Board Members noted that Nuveen’s net margins were higher in 2018 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 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 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 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.
The Independent Board Members 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 recognized that other reasonable allocation methodologies could be employed and lead to significantly different results. The Board 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 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 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 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.
71
Annual Investment Management Agreement Approval Process (continued)
Based on a consideration of all the information provided, the Board 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 noted that although economies of scale are difficult to measure, the Adviser shares the benefits of economies of scale in various ways including breakpoints in the management fee schedule (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 funds for the fees paid. The Board noted that the Nuveen funds generally pay the Adviser a management fee comprised of a fund-level component and a complex-level component each with its own breakpoint schedule. The Board recognized that the Nuveen ETFs (including each Fund) pay a unitary fee and as a result, any reduction in fixed costs associated with with the management of a Fund 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 each Fund. The Independent Board Members considered that the unified fees generally provide inherent economies of scale because each Fund would maintain a competitive fixed fee over the annual contract period even if such Fund’s assets declined and/or operating costs rose. As the Nuveen ETFs, including the Funds, 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.
In addition, the Independent Board Members 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 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. The Independent Board Members 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 Fund portfolio transactions.
Based on their 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);
72
• 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”).
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.
73
Annual Investment Management Agreement Approval Process (continued)
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 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
74
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.
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.
75
Annual Investment Management Agreement Approval Process (continued)
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.
