Chair’s Letter
to Shareholders

Dear Shareholders,
The COVID-19 crisis is taking an unprecedented toll on our health, societies, economies and financial markets. Our thoughts are with you during this time of significant disruption caused by the disease and its economic fallout. With many regions of the world suppressing the initial spread of the virus, governments and public health officials face the extraordinary challenge of balancing the resumption of economic activity with public safety, particularly as new clusters of infection have emerged in the U.S. and other countries following their reopening. Markets have turned their focus to the potential for an economic recovery, although the timing and magnitude are highly uncertain. Elevated market volatility is likely to continue, with economic data, coronavirus infection rates and the upcoming U.S. presidential election under scrutiny.
While we do not want to understate the dampening effect on the global economy, it is important to differentiate short-term interruptions from the longer-lasting implications to the economy. Prior to the COVID-19 crisis, some areas of the global economy were showing signs of improvement after trade tensions had weighed on economic activity for much of 2019. More recently, countries that have reopened have seen marked improvement in some near-term economic indicators. Central banks and governments around the world have announced economic stimulus measures and pledged to continue doing what it takes to support their economies. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced similar programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. Government has approved three relief packages, including a $2 trillion-dollar package directly supporting businesses and individuals. The Coronavirus Aid, Relief and Economic Security Act, called the CARES Act, provides direct payments and expanded unemployment benefits to individuals, loans and grants to small businesses, loans and other money to large corporations and funding for hospitals, public health, education and state and local governments.
In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial professional, who can review your time horizon, risk tolerance and investment goals. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.
Sincerely,


Terence J. Toth
Chair of the Board

Portfolio Managers’ Comments
Nuveen Municipal 2021 Target Term Fund (NHA)
These Funds feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen Fund Advisors, LLC, the Fund’s investment adviser. Portfolio managers John V. Miller, CFA, and Steven M. Hlavin discuss U.S. economic and market conditions, key investment strategies and the twelve-month performance of NHA. John and Steve have managed NHA since its inception in 2016.
What factors affected the U.S. economy and the national municipal market during the twelve-month reporting period ended May 31, 2020?
The longest economic expansion in U.S. history came to an abrupt halt in early 2020 amid the COVID-19 coronavirus pandemic. To slow the spread of the virus, large portions of the economy were shut down, with companies closing either temporarily or permanently and most of the U.S. population under stay-at-home orders during March and April 2020. A phased reopening began toward the end of May and continued after the close of the reporting period. The disruption has been swift and severe, and has tipped the economy into recession, a several months’ long contraction across the broad economy. (Subsequent to the close of this reporting period, in June 2020, the National Bureau of Economic Research announced that the economic expansion that began in June 2009 officially ended in February 2020, marking the start of a recession.) For the first quarter of 2020, the Bureau of Economic Analysis reported that annualized gross domestic product (GDP) shrank 5.0%, according to its “second” estimate. GDP measures the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes. Previously, the economy had been expanding at a moderate clip. GDP grew at an annualized rate of 2.1% in the fourth quarter of 2019 and grew 2.3% in 2019 overall.
Consumer spending, the largest driver of the economy, was well supported earlier in this reporting period by low unemployment, wage gains and tax cuts. However, the COVID-19 crisis containment measures drove a significant drop in consumer spending and a sharp rise in unemployment in March and April 2020. The Bureau of Labor Statistics said the unemployment rate rose to 13.3% in May 2020 from 3.6% in May 2019. Although May 2020 saw a surprise addition of 2.7 million jobs during the month as economies began to reopen, the combined job losses in March and April 2020 exceeded 22 million. The average hourly earnings rate appeared to soar, growing at an annualized rate of 6.5% in May 2020, despite the spike in unemployment. Earnings data were skewed by the concentration of job losses in lower-wage work, which effectively eliminated most of the low data, resulting in an average of mostly higher numbers. The overall trend of inflation weakened considerably, which was attributed to large decreases in gasoline, apparel, air travel

and lodging prices offsetting an increase in food prices. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 0.1% over the twelve-month reporting period ended May 31, 2020 before seasonal adjustment.
Low mortgage rates and low inventory drove home prices moderately higher in this reporting period, although the most recent data do not fully reflect the shutdown. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, was up 4.7% year-over-year in April 2020 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 3.4% and 4.0%, respectively.
With economic momentum slowing in 2019 from 2018’s stronger pace, the U.S. Federal Reserve (Fed) left rates unchanged throughout the first half of 2019 then cut rates by 0.25% at each of the July 2019, September 2019 and October 2019 policy committee meetings. Markets registered disappointment with the Fed’s explanation that the rate cuts were a “mid-cycle adjustment,” rather than a prolonged easing period, and its signal that there would be no additional rate cuts in 2019. Also in the latter half of 2019, the Fed announced it would stop shrinking its bond portfolio sooner than scheduled, as well as began buying short-term Treasury bills to help money markets operate smoothly and maintain short-term borrowing rates at low levels. Fed Chairman Powell emphasized that the Treasury bill purchases were not a form of quantitative easing. The Fed continued its Treasury bill buying in January 2020, as well as left its benchmark interest rate unchanged, while noting the emerging COVID-19 risks.
As the outbreak spread to the U.S. and significant restrictions on social and economic activity were imposed starting in March 2020, the Fed enacted an array of emergency measures to stabilize the financial system and support the markets, including cutting its main interest rate to near zero, offering lending programs to aid small and large companies and allowing unlimited bond purchases, known as quantitative easing. There were no policy changes at the Fed’s April 2020 meeting, where Chairman Powell reiterated a commitment to keep rates near zero until the economy recovers, and the meeting minutes released during May 2020 underscored the Fed’s concerns about a potentially prolonged economic recovery.
Meanwhile, the U.S. government approved three aid packages, totaling more than $100 billion in funding to health agencies and employers offering paid leave and $2 trillion allocated across direct payments to Americans, an expansion of unemployment insurance, loans to large and small businesses, funding to hospitals and health agencies and support to state and local governments.
While trade and tariff policy drove market sentiment for most of the twelve-month reporting period, the outbreak of the novel coron-avirus and its associated disease COVID-19 rapidly dwarfed all other market concerns starting in late February 2020. Equity and commodity markets sold-off and safe-haven assets rallied in March 2020 as China, other countries and then the United States initiated quarantines, restricted travel and shuttered factories and businesses. The potential economic shock was particularly difficult to assess, which amplified market volatility. An ill-timed oil price war between the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC member Russia, which caused oil prices to plunge in March 2020, exacerbated the market sell-off.
Outside the U.S., many countries implemented lockdowns and restrictions on business activity to reduce infection rates, with a deep impact to their economies. Pandemic responses included central bank monetary easing and quantitative easing, fiscal relief programs, the loosening of fiscal rules and, in the case of emerging markets, emergency financing and debt relief from bilateral creditors and international organizations such as the International Monetary Fund and World Bank. The U.K. formally exited the European Union (EU) at the end of January 2020, triggering the one-year transition period, but Brexit talks were temporarily paused during the virus lockdown. When negotiations resumed, the U.K. continued to indicate it would not seek an extension. Italy’s prime minister unexpectedly resigned in August 2019, and the newly formed coalition government appeared to take a less antagonistic stance towards the EU. To help relieve the coronavirus impact on Italy and other more indebted Southern European countries, the European Commission proposed a €750 billion aid program to be funded by all member states, although it is expected to face a bumpy approval process. In Asia, northern countries were among the first to successfully reduce infection rates and relax coronavirus restrictions, but pockets of

the disease re-emerged. The widespread anti-government protests roiling Hong Kong throughout 2019 had dissipated amid the lock-down, but tensions flared in late May 2020 when China unexpectedly announced a national security law perceived as a threat to Hong Kong’s sovereignty. India took stringent lockdown steps in March 2020 but still saw a rapid increase in cases. Latin American countries entered the health crisis in already weakened positions, with high government debt and widespread civil unrest. Venezuela’s economic and political crisis continued to deepen. Argentina surprised the market with the return of a less market-friendly administration but continued to pursue a restructuring of its debt. Brazil’s Bolsonaro administration achieved a legislative win on pension reform but had not fully delivered on reviving economic growth. As the pandemic spread to Latin America, the inconsistent government responses, reduced testing capabilities, weaker health care systems, food shortages and public protests contributed to accelerating infection and death rates, while the Southern Hemisphere winter is set to begin.
Prior to the COVID-19 crisis, global markets had become more bullish on the outlook for 2020 as trade policy and Brexit appeared to make progress at the end of 2019. The U.S. and China agreed on a partial trade deal, which included rolling back some tariffs, increasing China’s purchases of U.S. agriculture products and the consideration of intellectual property, technology and financial services rights. The “phase one” deal was signed on January 15, 2020. While much of the focus remained on the U.S.-China relationship, trade spats between the U.S. and Mexico, the EU, Brazil and Argentina also arose throughout the reporting period. In January 2020, the U.S. Congress fully approved the U.S., Mexico and Canada Agreement (USMCA), which replaces the North American Free Trade Agreement. With more clarity on trade deals, the trade-related deterioration in global manufacturing and export data was expected to improve. However, the COVID-19 crisis has since upended those assumptions. Furthermore, tensions between the U.S. and China escalated amid the pandemic, with both sides stoking resentment about the management of the health crisis, Hong Kong’s political protests and trade policy.
Despite the severe sell-off in March 2020, municipal bonds managed positive performance over the twelve-month reporting period. For most of the reporting period, a significant decline in interest rates drove municipal bond prices higher, with positive technical and fundamental conditions also supporting credit spread tightening. Prior to the emergence of the novel coronavirus, interest rates had been pressured lower by signs that the economy’s momentum was slowing, a more dovish central bank policy, geopolitical tensions (especially regarding trade) and bouts of equity market volatility. Then, from late February through March 2020, coronavirus risks permeated the markets, sending U.S. Treasury yields to historic lows. Rate volatility increased sharply in that six-week period. As liquidity became stressed, investors began to liquidate any asset possible, including municipal bonds. Municipal bond prices declined rapidly (and yields spiked higher), amid rampant selling across both the high grade and high yield segments that was exacerbated in some cases by exchange-traded fund and closed-end fund selling. Municipal bond prices became severely dislocated from Treasury prices. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. Monetary and fiscal interventions from the Fed and U.S. government helped the market recover in April and May, although spreads remain wider than average as of the end of the reporting period. The municipal yield curve steepened over this reporting period, with a pronounced drop in yields at the short end of the curve spearheading the steepening.
Prior to the market turmoil in March 2020, municipal bond gross issuance nationwide had been robust. The overall low level of interest rates encouraged issuers to continue to actively refund their outstanding debt. In these transactions the issuers are issuing new bonds and taking the bond proceeds and redeeming (calling) old bonds. These refunding transactions have ranged from 30% to 60% of total issuance over the past few years. Thus, the net issuance (all bonds issued less bonds redeemed) is actually much lower than the gross issuance. So, while gross issuance volume has been adequate, the net has not and this was an overall positive technical factor on municipal bond investment performance in recent years. Notably, taxable municipal bond issuance has increased meaningfully since the advent of the Tax Cut and Jobs Act of 2017, which prohibits municipal issuers from issuing new tax-exempt bonds to pre-refund existing tax-exempt bonds. However, municipalities have taken advantage of the low interest rate environment

Portfolio Managers’ Comments (continued)
and the strong demand for yield to issue taxable municipal debt, enabling them to save on net interest costs while adding to the scarcity value of tax-exempt issues.
Municipal bond funds saw consistently positive cash flows throughout 2019, but demand has been uneven in 2020 so far. Positive flows continued into early 2020, then municipal bond funds suffered significant outflows in March 2020, particularly from high yield municipal bond funds. After the market stabilized in April 2020, fund flows turned positive again in May 2020. With interest rates in the U.S. and globally remaining near all-time lows, the appetite for yield has continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have adjusted to the 2017 tax law, which caps the state and local tax (SALT) deduction for individuals, there has been increased demand for tax-exempt municipal bonds, especially in states with high income taxes and/or property taxes.
What key strategies were used to manage the Fund during the twelve-month reporting period ended May 31, 2020?
The Fund invests in a portfolio of primarily municipal securities, the income from which is exempt from regular U.S. federal income tax. At least 65% of its managed assets are invested in low- to medium-quality municipal securities that, at the time of investment, are rated BBB/Baa or lower or unrated but judged by the portfolio managers to be of comparable quality. The Fund does not invest in securities rated CCC+/Caa1 or lower, or unrated but judged by the portfolio managers to be of comparable quality, nor does it invest in defaulted or distressed securities at the time of investment. No more than 25% will be in any one sector, no more than 5% in any one issuer and no more than 10% in tobacco settlement bonds. Up to 20% may be invested in securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals (AMT bonds).
The Fund seeks to identify municipal securities across diverse sectors and industries that the managers believe are underrated or undervalued. In seeking to return the original NAV on or about March 1, 2021, the Fund intends to utilize various portfolio and cash-flow management techniques, including setting aside a portion of its net investment income, possibly retaining gains and limiting the longest maturity of any holding to no later than September 1, 2021.
As of the end of the reporting period, NHA’s maturity profile was structured with approximately 26% maturing in 2020 and the remainder maturing in 2021. As we continue to seek bonds that may be appropriate for the Fund, to the extent possible, we’ll focus on buying 2021 maturities while looking to sell the earlier maturities first, to continue to reduce the Fund’s interest rate sensitivity as the Fund approaches its term date. The Fund’s credit quality and sector positioning remained in line with Nuveen’s ongoing strategic emphasis on lower rated (including below investment grade) credits and sectors offering higher yields. The Fund’s portfolio turnover was relatively muted in this reporting period as we found opportunities to buy bonds maturing in 2021, to reinvest the small amount of proceeds from maturing and called bonds and sinking fund payments.
We should also note that NHA received Energy Harbor common stock during this reporting period, after FirstEnergy Solutions emerged from bankruptcy and the restructured company was renamed Energy Harbor. The Fund received Energy Harbor stock when its holding of bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of its debt reorganization and emergence from bankruptcy protection, which was completed in February 2020. Due in part to post-emergence price increases, at the end of the reporting period Energy Harbor equity represented 3.7% of the total investments of NHA. Subsequent to the end of the reporting period, the value of Energy Harbor equity fell sharply after federal authorities charged certain Ohio politicians and lobbyists with having accepted large payments from an unnamed company (which was easily identifiable as Energy Harbor’s pre-bankruptcy parent, FirstEnergy Corp.) in what was alleged to be a corrupt scheme to adopt legislation that would benefit that parent company.

How did the Fund perform during the twelve-month reporting period ended May 31, 2020?
The table in the Fund’s Performance Overview and Holding Summaries section of this report provides the Fund’s total returns for the one-year and since-inception periods ended May 31, 2020. The Fund’s total returns at common share net asset value (NAV) are compared with the performance of a corresponding market index.
For the twelve months ended May 31, 2020, the total returns at common share NAV for NHA outperformed the return for the S&P Short Duration Municipal Yield Index.
Nearly all of the Fund’s outperformance relative to the benchmark is attributable to the Fund’s significantly shorter duration. As NHA approaches its 2021 target term date, the portfolio’s duration has naturally drifted lower, whereas the benchmark continuously rebalances to maintain its duration target. NHA’s duration has now declined to 3.5 years shorter than the benchmark’s duration, making the Fund less sensitive to the interest rate volatility in this reporting period. The best performing bonds in the portfolio on an absolute basis were the shortest dated bonds. NHA had exposure to some of the same issuers as the benchmark, but the Fund’s preference for the shorter dated bonds of those issuers contributed positively to relative performance. NHA did particularly well in its industrial development revenue (IDR) position, where it held a large exposure to Energy Harbor (formerly FirstEnergy Solutions) and smaller weightings in American Airlines, Inc., United Airlines Inc. and BP Pipelines Inc. As noted above, the strong performance of Energy Harbor has partially reversed itself since the end of the reporting period.

*     
Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is based on a federal income tax rate of 40.8%. The Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on payments made during the previous calendar year) that was not exempt from federal income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.
The Fund seeks to pay regular monthly dividends out of its net investment income at a rate that reflects its past and projected net income performance. To permit the Fund to maintain a more stable monthly dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net income actually earned by the Fund during the period. Distributions to common shareholders are determined on a tax basis, which may differ from amounts recorded in the accounting records. In instances where the monthly dividend exceeds the earned net investment income, the Fund would report a negative undistributed net ordinary income. Refer to Note 6 – Income Tax Information for additional information regarding the amounts of undistributed net ordinary income and undistributed net long-term capital gains and the character of the actual distributions paid by the Fund during the period.
All monthly dividends paid by the Fund during the current reporting period were paid from net investment income. If a portion of the Fund’s monthly distributions is sourced or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders will be notified of those sources. For financial reporting purposes, the per share amounts of the Fund’s distributions for the reporting period are presented in this report’s Financial Highlights. For income tax purposes, distribution information for the Fund as of its most recent tax year end is presented in Note 6 – Income Tax Information within the Notes to Financial Statements of this report.

The Fund has an investment objective to return $9.85 (the original net asset value following the Fund’s initial public offering (the “Original NAV”)) to common shareholders on or about the end of the Fund’s term. There can be no assurance that the Fund will be able to return the Original NAV to shareholders, and such return is not backed or otherwise guaranteed by the Fund’s investment adviser, Nuveen Fund Advisors, LLC (the “Adviser”), or any other entity.
The Fund’s ability to return Original NAV to common shareholders on or about the termination date will depend on market conditions and the success of various portfolio and cash flow management techniques. The Fund currently intends to set aside and retain in its net assets a portion of its net investment income and possibly all or a portion of its gains. This will reduce the amounts otherwise available for distribution prior to the liquidation of the Fund, and the Fund may incur taxes on such retained amount, which will reduce the overall amounts that the Fund would have otherwise been able to distribute. Such retained income or gains, net of any taxes, would constitute a portion of the liquidating distribution returned to investors at the end of the Fund’s term. In addition, the Fund’s investment in shorter term and lower yielding securities, especially as the Fund nears the end of its term, may reduce investment income and, therefore, the monthly dividends during the period prior to termination. Investors that purchase common shares in the secondary market (particularly if their purchase price differs meaningfully from the Original NAV) may receive more or less than their original investment.

Risk Considerations
Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation.
Nuveen Municipal 2021 Target Term Fund (NHA)
Investing in closed-end funds involves risk; principal loss is possible. There is no guarantee the Fund’s investment objectives will be achieved. Closed-end fund shares may frequently trade at a discount or premium to their net asset value. Debt or fixed income securities, such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, derivatives risk, liquidity risk, and income risk. As interest rates rise, bond prices fall. Lower credit debt securities may be more likely to fail to make timely interest or principal payments. For these and other risks, including the Fund’s limited term and inverse floater risk, see the Fund’s web page at www.nuveen.com/NHA.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Trustees of
Nuveen Municipal 2021 Target Term Fund:



Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities of Nuveen Municipal 2021 Target Term Fund (the Fund), including the portfolio of investments, as of May 31, 2020, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years in the four-year period then ended and the period January 26, 2016 (commencement of operations) through May 31, 2016. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of May 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the four-year period then ended and the period from January 26, 2016 through May 31, 2016, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of May 31, 2020, by correspondence with custodians and brokers or other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.
/s/ KPMG LLP
We have served as the auditor of one or more Nuveen investment companies since 2014.

(a)
Total Return Based on Common Share NAV is the combination of changes in common share NAV, reinvested dividend income at NAV and reinvested capital gains distributions at NAV, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending NAV. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized.

Total Return Based on Common Share Price is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.
(b)
• Net Investment Income (Loss) ratios reflect income earned and expenses incurred on assets attributable to preferred shares issued by the Fund, where applicable.
• The expense ratios reflect, among other things, all interest expense and other costs related to preferred shares where applicable, as follows:

Notes to
Financial Statements
1. General Information
Fund Information
The fund covered in this report and its corresponding New York Stock Exchange (“NYSE”) symbol is Nuveen Municipal 2021 Target Term Fund (NHA) (the “Fund”). The Fund is registered under the Investment Company Act of 1940 (the “1940 Act”), as amended, as a diversified closed-end management investment company. The Fund was organized as a Massachusetts business trust on October 13, 2015.
The Fund seeks to return its original $9.85 net asset value (“NAV”) per common share on or about March 1, 2021.
The end of the reporting period for the Fund is May 31, 2020, and the period covered by these Notes to Financial Statements is for the fiscal year ended May 31, 2020 (the “current fiscal period”).
Investment Adviser and Sub-Adviser
The Fund’s 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 Fund, oversees the management of the Fund’s portfolio, manages the Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into a sub-advisory agreement with Nuveen Asset Management, LLC (the “Sub-Adviser”), a subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolio of the Fund.
Other Matters
The outbreak of the novel coronavirus (“COVID-19”) and subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the calendar quarter ended March 31, 2020. The worldwide spread of COVID-19 has created significant uncertainty in the global economy. The duration and extent of COVID-19 over the long-term cannot be reasonably estimated at this time. The ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Fund’s normal course of business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Management continues to monitor and evaluate this situation.
2. Significant Accounting Policies
The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. The Fund is an investment company and follows the accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services—Investment Companies. The NAV for financial reporting purposes may differ from the NAV for processing security and common share transactions. The NAV for financial reporting purposes includes security and common share transactions through the date of the report. Total return is computed based on the NAV used for processing security and common share transactions. The following is a summary of the significant accounting policies consistently followed by the Fund.
Compensation
The Fund 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 Fund from the Adviser or its affiliates. The Fund’s Board of Trustees (the “Board”) has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.
Distributions to Common Shareholders
Distributions to common shareholders are recorded on the ex-dividend date. The amount, character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.
Indemnifications
Under the Fund’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts that provide general indemnifications to other parties. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund 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 accretion of discounts for financial reporting purposes, and is recorded on an accrual basis. Interest income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash.
Netting Agreements
In the ordinary course of business, the Fund may enter into transactions subject to enforceable International Swaps and Derivatives Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows the Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, the Fund manages its cash collateral and securities collateral on a counterparty basis.
The Fund’s investments subject to netting agreements as of the end of the reporting period, if any, are further described in Note 4 – Portfolio Securities and Investments in Derivatives.
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 Fund and it did not have a material impact on the Fund’s financial statements.
Fair Value Measurement: Disclosure Framework
During August 2018, the FASB issued ASU 2018-13 (“ASU 2018-13”), Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements. ASU 2018-13 modifies the disclosures required by Topic 820, Fair Value Measurements. The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Management has early implemented this guidance and it did not have a material impact on the Fund’s financial statements.
Reference Rate Reform
In March 2020, FASB issued ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The main objective of the new guidance is to provide relief to companies that will be impacted by the expected change in benchmark interest rates at the end of 2021, when participating banks will no longer be required to submit London Interbank Offered Rate (LIBOR) quotes by the UK Financial Conduct Authority (FCA). The new guidance allows companies to, provided the only change to existing contracts are a change to an approved benchmark interest rate, account for modifications as a continuance of the existing contract without additional analysis. For new and existing contracts, the Fund may elect to apply the amendments as of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the amendments, but is currently assessing the impact of the ASU’s adoption to the Fund’s financial statements and various filings.
3. Investment Valuation and Fair Value Measurements
The fair valuation input levels as described below are for fair value measurement purposes.
The Fund’s 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 spread, 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
31

Notes to Financial Statements (continued)
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.
Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1. Securities primarily traded on the Nasdaq National Market (“Nasdaq”) are valued, at the Nasdaq Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or Nasdaq for which there were no transactions on a given day or securities not listed on a securities exchange or Nasdaq are valued at the quoted bid price and are generally classified as Level 2.
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 the Fund’s NAV (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Board and/or its appointee.
The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of the Fund’s fair value measurements as of the end of the reporting period:

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.
Investment Transactions 
 

Long-term purchases and sales (including maturities) during the current fiscal period were as follows: 
 
Purchases 
$13,049,034 
Sales and maturities 
12,824,982 
 
The Fund 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 Fund has earmarked securities in its portfolio with a current value at least equal to the amount of the when issued/delayed-delivery purchase commitments. If the 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
The Fund is authorized to invest in certain derivative instruments such as futures, options and swap contracts. The Fund limits its investments in futures, options on futures and swap contracts to the extent necessary for the Adviser to claim the exclusion from registration by the Commodity Futures Trading Commission as a commodity pool operator with respect to the Fund. The Fund records derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Fund’s investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.
Although the Fund is authorized to invest in derivative instruments, and may do so in the future, it did not make any such investments during the current fiscal period.
Market and Counterparty Credit Risk
In the normal course of business the 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 the Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of the 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.
The 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 the Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when the Fund has an unrealized loss, the Fund has instructed the custodian to pledge assets of the Fund 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
Common Share Transactions
There were no transactions in common shares during the Fund’s current and prior fiscal periods.
6. Income Tax Information
The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. In any year, the Fund may choose to distribute all or a portion of net investment income and net capital gains to shareholders, or retain a portion of its net investment income and net capital gains and pay corporate income taxes on such retained net investment income and retained net capital gains. The Fund intends to distribute at least the percentage of its net investment income and gains to maintain its status as a regulated investment company for U.S. federal income tax purposes.
Furthermore, the Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income tax, to retain such tax-exempt status when distributed to shareholders of the Fund. Net realized capital gains and ordinary income distributions paid by the Fund are subject to federal taxation.
For all open tax years and all major taxing jurisdictions, management of the Fund 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 Fund 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 taxable market discount and 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 NAV of the Fund.

7. Management Fees and Other Transactions with Affiliates 
 
Management Fees
The Fund’s management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Sub-Adviser is compensated for its services to the Fund from the management fees paid to the Adviser.
The Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within the Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables Fund shareholders to benefit from growth in the assets within the Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.
34

Table of Contents
 

The annual fund-level fee, payable monthly, is calculated according to the following schedule: 
 
Average Daily Managed Assets* 
Fund-Level Fee Rate 
For the first $125 million 
0.4000% 
For the next $125 million 
0.3875 
For the next $250 million 
0.3750 
For the next $500 million 
0.3625 
For the next $1 billion 
0.3500 
For the next $3 billion 
0.3250 
For managed assets over $5 billion 
0.3125 
 
The annual complex-level fee, payable monthly, is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule by the Fund’s daily managed assets:
   
Complex-Level Eligible Asset Breakpoint Level*

*     
For the complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the fund’s use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen open-end and close-end funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen funds and assets in excess of a determined amount (originally $2 billion) added to the Nuveen fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011, but do not include certain assets of certain Nuveen funds that were reorganized into funds advised by an affiliate of the Adviser during the 2019 calendar year. As of May 31, 2020, the complex-level fee for the Fund was 0.1587%.
Other Transactions with Affiliates
The Fund is permitted to purchase or sell securities from or to certain other funds or accounts managed by the Sub-Adviser (“Affiliated Entity”) under specified conditions outlined in procedures adopted by the Board (“cross-trade”). These procedures have been designed to ensure that any cross-trade of securities by the Fund from or to an Affiliated Entity by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 under the 1940 Act. These transactions are effected at the current market price (as provided by an independent pricing service) without incurring broker commissions.
During the current fiscal period, the Fund did not engage in cross-trades pursuant to these procedures.
8. Borrowing Arrangements
Committed Line of Credit
The Fund, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, $2.65 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for various purposes other than leveraging for investment purposes. Each Participating Fund is allocated a designated proportion of the facility’s capacity (and its associated costs, as described below) based upon a multi-factor assessment of the likelihood and frequency of its need to draw on the facility, the size of the Fund and its anticipated draws, and the potential importance of such draws to the operations and well-being of the Fund, relative to those of the other Funds. A Fund may effect draws on the facility in excess of its designated capacity if and to the extent that other Participating Funds have undrawn capacity. The credit facility expires in June 2020 unless extended or renewed.
35

Table of Contents
 

Notes to Financial Statements (continued)
The credit facility has the following terms: a fee of 0.15% per annum on unused commitment amounts, and interest at a rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.00% per annum or (b) the Fed Funds rate plus 1.00% per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Other expenses” on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund.
During the current fiscal period, the Fund did not utilize this facility.
Inter-Fund Borrowing and Lending
The Securities and Exchange Commission (“SEC”) has granted an exemptive order permitting registered open-end and closed-end Nuveen funds to participate in an inter-fund lending facility whereby the Nuveen funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds, including the Fund covered by this shareholder report, will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business day’s notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board is responsible for overseeing the Inter-Fund Program.
The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.
During the current reporting period, the Fund did not enter into any inter-fund loan activity.
9. Subsequent Events
Committed Line of Credit
During June 2020, the Participating Funds renewed the standby credit facility through June 2021. In conjunction with this renewal the commitment amount decreased from $2.65 billion to $2.405 billion and the interest rate increased from LIBOR plus 1.00% to LIBOR plus 1.25%. The Participating Funds also incurred a 0.10% upfront fee. All other terms remain unchanged.
Energy Harbor Common Stock Decline
Subsequent to the end of the reporting period, the value of Energy Harbor (the “Company”) fell sharply after federal authorities charged certain Ohio politicians and lobbyists with having accepted large payments from an unnamed company (which was easily identifiable as Energy Harbor’s pre-bankruptcy parent, FirstEnergy Corp.) in what was alleged to be a corrupt scheme to adopt legislation that would benefit that parent company. As of May 31, 2020, the Fund held shares of common stock in the Company. At the time of issuance of these financial statements, the value of the common stock has been adversely impacted as compared to the value reported in the Portfolio of Investments as of May 31, 2020. Management continues to monitor and evaluate this situation.

Glossary of Terms Used in this Report (Unaudited)
Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.
Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond fund’s value to changes when market interest rates change. Generally, the longer a bond’s or fund’s duration, the more the price of the bond or fund will change as interest rates change.
Effective Leverage: Effective leverage is a fund’s effective economic leverage, and includes both regulatory leverage (see leverage) and the leverage effects of certain derivative investments in a fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.
Gross Domestic Product (GDP): The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.
Industrial Development Revenue Bond (IDR): A unique type of revenue bond issued by a state or local government agency on behalf of a private sector company and intended to build or acquire factories or other heavy equipment and tools.
Inverse Floating Rate Securities: Inverse floating rate securities, also known as inverse floaters or tender option bonds (TOBs), are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a Fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.
Leverage: Leverage is created whenever a fund has investment exposure (both reward and/or risk) equivalent to more than 100% of the investment capital.
Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund’s Net Assets divided by its number of shares outstanding.
Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.
38

Table of Contents
 

S&P Short Duration Municipal Yield Index: An index that contains all bonds in the S&P Municipal Bond Index that mature between 1 month and 12 years, and maintains a 10% weighting to AA rated bonds, 10% to A rated bonds, 20% to BBB rated bonds and 60% to below investment grade and non-rated bonds. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
Total Investment Exposure: Total investment exposure is a fund’s assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a fund’s use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.
Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

Reinvest Automatically, Easily and Conveniently
Nuveen makes reinvesting easy. A phone call is all it takes to set up your reinvestment account.
Nuveen Closed-End Funds Automatic Reinvestment Plan
Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares. By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.

Easy and convenient
To make recordkeeping easy and convenient, each month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.
How shares are purchased
The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value on the last business day immediately prior to the purchase date. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.
Flexible
You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change. You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan. The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

Annual Investment Management Agreement Approval Process (Unaudited)
At a meeting held on May 19-21, 2020 (the “May Meeting”), the Board of Trustees (the “Board” and each Trustee, a “Board Member”) of the Fund, which is comprised entirely of Board Members who are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) (the “Independent Board Members”), approved the renewal of the management agreement (the “Investment Management Agreement”) with Nuveen Fund Advisors, LLC (the “Adviser”) pursuant to which the Adviser serves as investment adviser to the Fund and the sub-advisory agreement (the “Sub-Advisory Agreement”) with Nuveen Asset Management, LLC (the “Sub-Adviser”) pursuant to which the Sub-Adviser serves as such to the Fund. Although the 1940 Act requires that continuances of the Advisory Agreements (as defined below) be approved by the in-person vote of a majority of the Independent Board Members, the May Meeting was held virtually through the internet in view of the health risks associated with holding an in-person meeting during the COVID-19 pandemic and governmental restrictions on gatherings. The May Meeting was held in reliance on an order issued by the Securities and Exchange Commission on March 13, 2020, as extended on March 25, 2020, which provided registered investment companies temporary relief from the in-person voting requirements of the 1940 Act with respect to the approval of a fund’s advisory agreement in response to the challenges arising in connection with the COVID-19 pandemic.
Following up to an initial two-year period, the Board considers the renewal of the Investment Management Agreement and Sub-Advisory Agreement on an annual basis. The Investment Management Agreement and Sub-Advisory Agreement are collectively referred to as the “Advisory Agreements” and the Adviser and the Sub-Adviser are collectively, the “Fund Advisers” and each, a “Fund Adviser.” Throughout the year, the Board and its committees meet regularly and, at these meetings, review an extensive array of topics and information that are relevant to its annual consideration of the renewal of the advisory agreements for the Nuveen funds. Such information may address, among other things, fund performance; the Adviser’s strategic plans; the review of the funds and investment teams; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers to the funds; valuation of securities; fund expenses; overall market and regulatory developments; the management of leverage financing; and the secondary market trading of the closed-end funds and any actions to address discounts.
In addition to the information and materials received during the year, the Board, in response to a request made on its behalf by independent legal counsel, received extensive materials and information prepared specifically for its annual consideration of the renewal of the advisory agreements for the Nuveen funds by the Adviser and by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials cover a wide range of topics including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of each sub-adviser to the Nuveen funds and the applicable investment teams; an analysis of fund performance in absolute terms and as compared to the performance of certain peer funds and benchmarks with a focus on any performance outliers; an analysis of the fees and expense ratios of the Nuveen funds in absolute terms and as compared to those of certain peer funds with a focus on any expense outliers; a description of portfolio manager compensation; a review of the secondary market trading of shares of the Nuveen closed-end funds (including, among other things, an analysis of performance, distribution and valuation and capital raising trends in the broader closed-end fund market and in particular with respect to Nuveen closed-end funds; a review of the leverage management actions taken on behalf of the Nuveen closed-end funds and their resulting impact on performance; and a description of the distribution management process and any capital management activities); a review of the performance of various service providers; a description of various initiatives Nuveen had undertaken or continued during the year for the benefit of particular fund(s) and/or the complex; a description of the profitability or financial data of Nuveen and the sub-advisers to the Nuveen funds; and a description of indirect benefits received by the Adviser and the sub-advisers as a result of their relationships with the Nuveen funds.

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
In continuing its practice, the Board met prior to the May Meeting to begin its considerations of the renewal of the Advisory Agreements. Accordingly, on April 27-28, 2020 (the “April Meeting”), the Board met to review and discuss, in part, the performance of the Nuveen funds and the Adviser’s evaluation of each sub-adviser to the Nuveen funds. In its review, the Board recognized the volatile market conditions occurring during the first half of 2020 arising, in part, from the public health crisis caused by the novel coronavirus known as COVID-19 and the resulting impact on fund performance. Accordingly, the Board reviewed, among other things, fund performance reflecting the more volatile periods, including for various time periods ended the first quarter of 2020 and for various time periods ended April 17, 2020. At the April Meeting, the Board Members asked questions and requested additional information that was provided for the May Meeting. In continuing its review of the Nuveen funds in light of the extraordinary market conditions experienced in early 2020, the Board received updated fund performance data reflecting various time periods ended May 8, 2020 for its May Meeting. The Board also continued its practice of seeking to meet periodically with the various sub-advisers to the Nuveen funds and their investment teams, when feasible.
The Independent Board Members considered the review of the advisory agreements for the Nuveen funds to be an ongoing process and employed the accumulated information, knowledge, and experience the Board Members had gained during their tenure on the boards governing the Nuveen funds and working with the Adviser and sub-advisers in their review of the advisory agreements. The contractual arrangements are a result of multiple years of review, negotiation and information provided in connection with the boards’ annual review of the Nuveen funds’ advisory arrangements and oversight of the Nuveen funds.
The Independent Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives from the Adviser or the Sub-Adviser were present. In connection with their annual review, the Independent Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements.
The Board’s decision to renew the Advisory Agreements was not based on a single identified factor, but rather the decision reflected the comprehensive consideration of all the information provided throughout the year and at the April and May Meetings, and each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the approval process. The following summarizes the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements and its conclusions.
A. Nature, Extent and Quality of Services
In evaluating the renewal of the Advisory Agreements, the Independent Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to the Fund with particular focus on the services and enhancements to such services provided during the last year. The Independent Board Members considered the Investment Management Agreement and the Sub-Advisory Agreement separately in the course of their review. With this approach, they considered the respective roles of the Adviser and the Sub-Adviser in providing services to the Fund.
With respect to the Adviser, the Board recognized that the Adviser has provided a vast array of services the scope of which has expanded over the years in light of regulatory, market and other developments, such as the development of expanded compliance programs for the Nuveen funds. The Board also noted the extensive resources, tools and capabilities the Adviser and its affiliates devoted to the various operations of the Nuveen funds. These services include, but are not limited to: investment oversight, risk management and securities valuation services (such as analyzing investment performance and risk data; overseeing and reviewing the various sub-advisers to the Nuveen funds and their investment teams; overseeing trade execution, soft dollar practices and securities lending activities; providing daily valuation services and developing related valuation policies, procedures and methodologies; overseeing risk disclosure; periodic testing of investment and liquidity risks; participating in financial statement and marketing disclosures; participating in product development; and participating in leverage management and liquidity monitoring); product management (such as analyzing a fund’s position in the marketplace, setting dividends,

preparing shareholder and intermediary communications and other due diligence support); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the funds’ independent public accountants and other service providers; managing fund budgets and expenses; and helping to fulfill the funds’ regulatory filing requirements); oversight of shareholder services and transfer agency functions (such as overseeing transfer agent service providers which include registered shareholder customer service and transaction processing; and overseeing proxy solicitation and tabulation services); Board relations services (such as organizing and administering Board and committee meetings, preparing various reports to the Board and committees and providing other support services); compliance and regulatory oversight services (such as devising compliance programs; managing compliance policies; monitoring compliance with applicable fund policies and laws and regulations; and evaluating the compliance programs of the various sub-advisers to the Nuveen funds and certain other service providers); legal support and oversight of outside law firms (such as helping to prepare and file registration statements and proxy statements; overseeing fund activities and providing legal interpretations regarding such activities; and negotiating agreements with other fund service providers); and providing leverage, capital and distribution management services.
The Board also recognized that the Adviser and its affiliates have undertaken a number of initiatives over the previous year that benefited the complex and/or particular Nuveen funds including, but not limited to:
•  Fund Improvements and Product Management Initiatives – continuing to proactively manage the Nuveen fund complex as a whole and at the individual fund level with an aim to enhance the shareholder outcomes through, among other things, rationalizing the product line and gaining efficiencies through mergers, repositionings and liquidations; reviewing and updating investment policies and benchmarks; and integrating certain investment teams and changing the portfolio managers serving various funds;
•  Capital Initiatives – continuing to invest capital to support new Nuveen funds with initial capital as well as to facilitate modifications to the strategies or structure of existing funds;
•  Compliance Program Initiatives – continuing efforts to mitigate compliance risk, increase operating efficiencies, strengthen key compliance program elements and support international business growth and other objectives through, among other things, integrating various investment teams across affiliates, consolidating marketing review functions, enhancing compliance related technologies and establishing and maintaining shared broad-based compliance policies throughout the organization and its affiliates;
•  Risk Management and Valuation Services - continuing efforts to provide Nuveen with a more disciplined and consistent approach to identifying and mitigating the firm’s operational risks through, among other things, enhancing the interaction and reporting between the investment risk management team and various affiliates and adopting a risk operational framework across the complex;
•  Regulatory Matters – continuing efforts to monitor regulatory trends and advocate on behalf of the Nuveen funds, to implement and comply with new or revised rules and mandates and to respond to regulatory inquiries and exams;
•  Government Relations – continuing efforts of various Nuveen teams and affiliates to develop policy positions on a broad range of issues that may impact the Nuveen funds, advocate and communicate these positions to lawmakers and other regulatory authorities and work with trade associations to ensure these positions are represented;
•  Business Continuity, Disaster Recovery and Information Services – continuing to periodically test business continuity and disaster recovery plans, maintain an information security program designed to identify and manage information security risks, and provide reports to the Board, at least annually, addressing, among other things, management’s security risk assessment, cyber risk profile, potential impact of new or revised laws and regulations, incident tracking and other relevant information technology risk-related reports;

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
•  Expanded Dividend Management Services – continuing to manage the dividends among the varying types of Nuveen funds within the Nuveen complex to be consistent with the respective fund’s product design and investing resources to develop systems to assist in the process for newer products such as target term funds; and
•  with respect specifically to closed-end funds, such initiatives also included:
••   Leverage Management Services - continuing to actively manage leverage including developing new leverage instruments, managing leverage exposure and costs through various providers, and managing and adapting tender option bond structures to comply with regulations and developing further relationships with leverage providers;
••   Capital Management, Market Intelligence and Secondary Market Services ongoing capital management efforts through shelf offerings, share repurchases as appropriate to address discounts, tender offers and capital return programs as well as providing market data analysis to help understand closed-end fund ownership cycles and their impact on secondary market trading as well as to improve proxy solicitation efforts; and
••   Closed-end Fund Investor Relations Program – maintaining the closed-end fund investor relations program which, among other things, raises awareness, provides educational materials and cultivates advocacy for closed-end funds and the Nuveen closed-end fund product line.
The Board also noted the benefits to shareholders of investing in a Nuveen fund, as each Nuveen fund is a part of a large fund complex with a variety of investment disciplines, capabilities, expertise and resources available to navigate and support the funds including during stressed times as occurred in the market in the first half of 2020. In addition to the services provided by the Adviser, the Board also considered the risks borne by the Adviser and its affiliates in managing the Nuveen funds, including entrepreneurial, operational, reputational, regulatory and litigation risks.
The Board further considered the division of responsibilities between the Adviser and the Sub-Adviser and recognized that the Sub-Adviser and its investment personnel generally are responsible for the management of the Fund’s portfolio under the oversight of the Adviser and the Board. The Board considered an analysis of the Sub-Adviser provided by the Adviser which included, among other things, the Sub-Adviser’s assets under management and changes thereto, a summary of the applicable investment team and changes thereto, the investment approach of the team and the performance of the funds sub-advised by the Sub-Adviser over various periods. The Board further considered at the May Meeting or prior meetings evaluations of the Sub-Adviser’s compliance program and trade execution. The Board also considered the structure of investment personnel compensation programs and whether this structure provides appropriate incentives to act in the best interests of the respective Nuveen funds. The Board noted that the Adviser recommended the renewal of the Sub-Advisory Agreement.
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 Fund under each applicable Advisory Agreement.
B. The Investment Performance of the Fund and Fund Advisers
In evaluating the quality of the services provided by the Fund Advisers, the Board also received and considered a variety of investment performance data of the Nuveen funds they advise. In this regard, the Board reviewed, among other things, Fund performance over the quarter, one-, and three-year periods ending December 31, 2019. Unless otherwise indicated, the performance data referenced below reflects the periods ended December 31, 2019. In general, the year 2019 was a period of strong market performance. However, as noted above, the Board recognized the unprecedented market volatility and decline that occurred in early 2020 and the significant impact it would have on fund performance. As a result, the Board reviewed performance data capturing more recent time periods, including performance data reflecting the first quarter of 2020 as well as performance data for various periods ended April 17, 2020 for its April Meeting and May 8, 2020 for its May Meeting.

The Board reviewed both absolute and relative fund performance during the annual review over the various time periods. With respect to the latter, the Board considered fund performance in comparison to the performance of peer funds (the “Performance Peer Group”) and recognized and/or customized benchmarks (i.e., generally benchmarks derived from multiple recognized benchmarks). For funds that had changes in portfolio managers, the Board considered performance data of such funds before and after such changes. In considering performance data, the Board is aware of certain inherent limitations with such data, including that differences between the objective(s), strategies and other characteristics of the Nuveen funds compared to the respective Performance Peer Group and/or benchmark(s) (such as differences in the use of leverage) as well as differences in the composition of the Performance Peer Group over time will necessarily contribute to differences in performance results and limit the value of the comparative information. To assist the Board in its review of the comparability of the relative performance, the Adviser has ranked the relevancy of the peer group to the funds as low, medium or high.
As noted above, the Board reviewed fund performance over various periods ended December 31, 2019 as well as the first quarter of 2020 and various time periods ended April 17, 2020 and May 8, 2020. In light of the significant market decline in the early part of 2020, the Board noted that a shorter period of underperformance may significantly impact longer term performance. Further, the Board recognized that performance data may differ significantly depending on the ending date selected and accordingly, performance results for periods ended at the year-end of 2019 may vary significantly from performance results for periods ended in the first quarter of 2020, particularly given the extraordinary market conditions at that time as the impact of COVID-19 and other market developments unfolded. The Board considered a fund’s performance in light of the overall financial market conditions. In addition, the Board recognized that shareholders may evaluate performance based on their own holding periods which may differ from the periods reviewed by the Board and lead to differing results.
The secondary market trading of shares of the Nuveen closed-end funds continues to be a priority for the Board given its importance to shareholders, and therefore data reflecting the premiums and discounts at which the shares of the closed-end funds trade is reviewed by the Board during its annual review and by the Board and/or its Closed-end Fund committee during its respective quarterly meetings throughout the year.
In addition to the performance data prepared in connection with the annual review of the advisory agreements of the Nuveen funds, the Board reviewed fund performance throughout the year at its quarterly meetings representing differing time periods and took into account the discussions that occurred at these Board meetings in evaluating a fund’s overall performance. The Board also considered, among other things, the Adviser’s analysis of each Nuveen fund’s performance, with particular focus on funds that were considered performance outliers (both overperformance and underperformance), the factors contributing to the performance and any steps taken to address any performance concerns. Given the volatile market conditions of early 2020, the Board considered the Adviser’s analysis of the impact of such conditions on the Nuveen funds’ performance.
The Board evaluated performance in light of various factors, including general market conditions, issuer-specific information, asset class information, fund cash flows and other factors. Accordingly, depending on the facts and circumstances, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below its benchmark or peer group for certain periods. However, with respect to any Nuveen funds for which the Board had identified performance issues, the Board monitors such funds closely until performance improves, discusses with the Adviser the reasons for such results, considers whether any steps are necessary or appropriate to address such issues, and reviews the results of any efforts undertaken.
The Board noted that each of the Nuveen target term funds has investment objectives which seek to provide a high level of current income or, in the case of the Fund, current income exempt from regular U.S. federal income tax, and to return its original net asset value per common share on or about its termination date. Given the heightened market volatility in early 2020 and the investment objectives of these funds to seek the return of original net asset value, the Board will continue to monitor each of these funds.

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
The Board noted that the Fund ranked in the third quartile of its Performance Peer Group and its performance was below the performance of its benchmark for the one- and three-year periods ended December 31, 2019. With the decline of the market in the first quarter of 2020, the Fund ranked in the third quartile of its Performance Peer Group and its performance was below the performance of its benchmark for the one- and three-year periods ended March 31, 2020. In its review, the Board recognized that the Performance Peer Group was classified as low for relevancy. The Board was satisfied with the Fund’s overall performance.
C. Fees, Expenses and Profitability
1. Fees and Expenses
As part of its annual review, the Board considered the contractual management fee and net management fee (the management fee after taking into consideration fee waivers and/or expense reimbursements, if any) paid by a fund to the Adviser in light of the nature, extent and quality of the services provided. The Board also considered the total operating expense ratio of each fund before and after any fee waivers and/or expense reimbursements. More specifically, the Independent Board Members reviewed, among other things, each fund’s gross and net management fee rates (i.e., before and after expense reimbursements and/or fee waivers, if any) and net total expense ratio in relation to those of a comparable universe of funds (the “Peer Universe”) established by Broadridge. The Independent Board Members reviewed the methodology Broadridge employed to establish its Peer Universe and recognized that differences between the applicable fund and its respective Peer Universe as well as changes to the composition of the Peer Universe from year to year may limit some of the value of the comparative data. The Independent Board Members also considered a fund’s operating expense ratio as it more directly reflected the shareholder’s costs in investing in the respective fund.
In their review, the Independent Board Members considered, in particular, each fund with a net expense ratio (excluding investment-related costs of leverage) 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. In addition, although the Board reviewed a fund’s total net expenses both including and excluding investment-related expenses (i.e., leverage costs) and taxes for certain of the closed-end funds, the Board recognized that leverage expenses will vary across funds and in comparison to peers because of differences in the forms and terms of leverage employed by the respective fund. Accordingly, in reviewing the comparative data between a fund and its peers, the Board generally considered the fund’s net expense ratio and fees (excluding leverage costs and leveraged assets) 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 Universe. 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.
In their review of the fee arrangements for the Nuveen funds, the Independent Board Members considered the management fee schedules, including the complex-wide and fund-level breakpoint schedules. The Board noted that across the Nuveen fund complex, the complex-wide fee breakpoints reduced fees by $56.6 million and fund-level breakpoints reduced fees by $66.8 million in 2019.
With respect to the Sub-Adviser, the Board also considered the sub-advisory fee schedule paid to the Sub-Adviser in light of the sub-advisory services provided to the Fund, the breakpoint schedule and comparative data of the fees the Sub-Adviser charges to other clients, if any. In its review, the Board recognized that the compensation paid to the Sub-Adviser is the responsibility of the Adviser, not the Fund.
The Independent Board Members noted that the Fund had a net management fee and a net expense ratio below its respective peer averages.
Based on its review of the information provided, the Board determined that the Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.

2. Comparisons with the Fees of Other Clients
In determining the appropriateness of fees, the Board also considered information regarding the fee rates the respective Fund Advisers charged to certain other types of clients and the type of services provided to these other clients. With respect to the Adviser and/or the Sub-Adviser, such other clients may include retail and institutional managed accounts, passively managed exchange-traded funds (“ETFs”) sub-advised by the Sub-Adviser but that are offered by another fund complex and municipal managed accounts offered by an unaffiliated adviser. With respect to the Sub-Adviser, the Board reviewed, among other things, the fee range and average fee of municipal retail wrap accounts and municipal institutional accounts.
In considering the fee data of other clients, the Board considered, among other things, the differences in the amount, type and level of services provided to the Nuveen funds relative to other clients as well as the differences in portfolio investment policies, investor profiles, account sizes and regulatory requirements, all of which contribute to the variations in the fee schedules. The Board recognized the complexity and myriad of services the Adviser had provided to the Nuveen funds compared to the other types of clients as the Adviser is principally responsible for all aspects of operating the funds, including complying with the increased regulatory requirements required when managing the funds as well as the increased entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the funds. Further, with respect to ETFs, the Board considered that Nuveen ETFs are passively managed compared to the active management of the other Nuveen funds which contributed to the differences in fee levels between the Nuveen ETFs and other Nuveen funds. In general, higher fee levels reflect higher levels of service provided by the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that the Sub-Adviser’s fee is essentially for portfolio management services and therefore more comparable to the fees it receives for retail wrap accounts and other external sub-advisory mandates. The Board concluded the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.
3. Profitability of Fund Advisers
In their review, the Independent Board Members considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2019 and 2018. The Board reviewed, among other things, Nuveen’s net margins (pre-tax) (both including and excluding distribution expenses); gross and net revenue margins (pre- and post-tax); revenues, expenses, and net income (pre-tax and after-tax and before distribution) of Nuveen for fund advisory services; and comparative profitability data comparing the margins of Nuveen compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) for each of the last two calendar years. The Board also reviewed the revenues and expenses the Adviser derived from its ETF product line for the 2018 and 2019 calendar years.
In reviewing the profitability data, the Independent Board Members recognized the subjective nature of calculating profitability as the information is not audited and is dependent on cost allocation methodologies to allocate expenses of Nuveen and its affiliates between the fund and non-fund businesses. The expenses to be allocated include direct expenses in servicing the Nuveen funds as well as indirect and/or shared costs (such as overhead, legal and compliance) some of which are attributed to the Nuveen funds pursuant to the cost allocation methodologies. The Independent Board Members reviewed a description of the cost allocation methodologies employed to develop the financial information and a summary of the history of changes to the methodology over the eleven-year period from 2008 to 2019. The Board had also appointed three Independent Board Members, along with the assistance of independent counsel, to serve as the Board’s liaisons to review the development of the profitability data and any proposed changes to the cost allocation methodology prior to incorporating any such changes and to report to the full Board. The Board recognized that other reasonable and valid allocation methodologies could be employed and could lead to significantly different results. Based on the data, the Independent Board Members noted that Nuveen’s net margins
47

Table of Contents
 

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
were higher in 2019 than the previous year and considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between the years. The Board also noted the reinvestments of some of the profits into the business through, among other things, the investment of seed capital in certain funds and continued investments in enhancements to information technology, internal infrastructure and data management improvements and global investment and innovation projects.
As noted above, the Independent Board Members also considered Nuveen’s margins from its relationship to the Nuveen funds compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) to Nuveen for the calendar years 2019 and 2018. The Independent Board Members noted that Nuveen’s margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers. The Independent Board Members, however, recognized that it is difficult to make comparisons of profitability with other investment adviser peers given that comparative data is not generally public and the calculation of profitability is subjective and affected by numerous factors (such as types of funds a peer manages, its business mix, its cost of capital, the numerous assumptions underlying the methodology used to allocate expenses and other factors) which can have a significant impact on the results.
Aside from Nuveen’s profitability, the Board recognized that the Adviser is a subsidiary of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). As such, the Board also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2019 and 2018 calendar years to consider the financial strength of TIAA. The Board recognized the benefit of having an investment adviser and its parent with significant resources, particularly during periods of market stress.
In addition to Nuveen, the Independent Board Members also considered the profitability of the Sub-Adviser from its relationships with the Nuveen funds. In this regard, the Independent Board Members reviewed, among other things, the Sub-Adviser’s revenues, expenses and net revenue margins (pre- and post-tax) for its advisory activities for the calendar year ended December 31, 2019 as well as its pre-tax and after-tax net revenue margins for 2019 compared to such margins for 2018. The Independent Board Members also reviewed a profitability analysis reflecting the revenues, expenses and revenue margin (pre-and post-tax) by asset type for the Sub-Adviser for the calendar year ended December 31, 2019 and the pre- and post-tax revenue margins from 2019 and 2018.
In evaluating the reasonableness of the compensation, the Independent Board Members also considered any other ancillary benefits derived by the respective Fund Adviser from its relationship with the Nuveen funds as discussed in further detail below.
Based on a consideration of all the information provided, the Board noted that Nuveen’s and the Sub-Adviser’s level of profitability was acceptable and not unreasonable in light of the services provided.
D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale
The Board considered whether there have been economies of scale with respect to the management of the Nuveen funds and whether these economies of scale have been appropriately shared with the funds. The Board recognized that although economies of scale are difficult to measure, there are several methods to help share the benefits of economies of scale, including breakpoints in the management fee schedule, fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in Nuveen’s business which can enhance the services provided to the funds for the fees paid. The Board noted that Nuveen generally has employed these various methods. In this regard, the Board noted that the management fee of the Adviser is generally comprised of a fund-level component and a complex-level component each with its own breakpoint schedule, subject to certain exceptions. The Board reviewed the fund-level and complex-level fee schedules. The Board considered that the fund-level breakpoint schedules are designed to share economies of scale with shareholders if the particular fund grows, and the complex-level breakpoint schedule is designed to deliver the benefits of economies of scale to shareholders when the eligible assets in the complex pass certain thresholds even if the assets of a particular fund are
48

unchanged or have declined. With respect to the Nuveen closed-end funds, the Board noted that, although such funds may from time-to-time make additional share offerings, the growth of their assets would occur primarily through the appreciation of such funds’ investment portfolios. Further, in the calculation of the complex-level component, the Board noted that it had approved the acquisition of several Nuveen funds by similar TIAA-CREF funds in 2019. However, to mitigate the loss of the assets of these Nuveen funds deemed eligible to be included in the calculation of the complex-wide fee when these Nuveen funds left the complex upon acquisition, Nuveen agreed to credit approximately $460 million to assets under management to the Nuveen complex in calculating the complex-wide component.
The Independent Board Members also recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system and other systems and platforms that will, among other things, support growth, simplify and enhance information sharing, and enhance the investment process to the benefit of all of the Nuveen funds.
Based on its review, the Board concluded that the current fee arrangements together with the Adviser’s reinvestment in its business appropriately shared any economies of scale with shareholders.
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 Board considered the compensation that an affiliate of the Adviser received for serving as co-manager in the initial public offerings of new closed-end funds and for serving as an underwriter on shelf offerings of existing closed-end funds. In addition, the Independent Board Members also noted that various sub-advisers (including the Sub-Adviser) may engage in soft dollar transactions pursuant to which they may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds, although the Board recognized that certain sub-advisers may be phasing out the use of soft dollars over time.
The Board, however, noted that the benefits for the Sub-Adviser when transacting in fixed-income securities may be more limited as such securities generally trade on a principal basis and therefore do not generate brokerage commissions. Further, the Board considered that although the Sub-Adviser may benefit from the receipt of research and other services that it may otherwise have to pay for out of its own resources, the research may also benefit the Nuveen funds to the extent it enhances the ability of the Sub-Adviser to manage such funds or is acquired through the commissions paid on portfolio transactions of other clients.
Based on their review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Fund 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 the Fund and that the Advisory Agreements be renewed.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Nuveen Municipal 2021 Target Term Fund

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

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

connection with statutory and regulatory filings or engagements.
     
         
2 “Audit Related Fees” are the aggregate fees billed for assurance and related services reasonably related to the performance of the audit or review of
 
financial statements that are not reported under “Audit Fees”. These fees include offerings related to the Fund’s common shares and leverage.
 
         
3 “Tax Fees” are the aggregate fees billed for professional services for tax advice, tax compliance, and tax planning. These fees include: all global
 
withholding tax services; excise and state tax reviews; capital gain, tax equalization and taxable basis calculation performed by the principal accountant.

SERVICES THAT THE FUND’S AUDITOR BILLED TO THE ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

The following tables show the amount of fees billed by KPMG LLP to Nuveen Fund Advisors, LLC (formerly Nuveen Fund Advisors, Inc.) (the “Adviser”), and any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (“Affiliated Fund Service Provider”), for engagements directly related to the Fund’s operations and financial reporting, during the Fund’s last two full fiscal years.

The tables also show the percentage of fees subject to the pre-approval exception. The pre-approval exception for services provided to the Adviser and any Affiliated Fund Service Provider (other than audit, review or attest services) waives the pre-approval requirement if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid to KPMG LLP by the Fund, the Adviser and Affiliated Fund Service Providers during the fiscal year in which the services are provided that would have to be pre-approved by the Audit Committee; (B) the Fund did not recognize the services as non-audit services at the time of the engagement; and (C) the services are promptly brought to the Audit Committee’s attention, and the Committee (or its delegate) approves the services before the Fund’s audit is completed.

NON-AUDIT SERVICES

The following table shows the amount of fees that KPMG LLP billed during the Fund’s last two full fiscal years for non-audit services. The Audit Committee is required to pre-approve non- audit services that KPMG LLP provides to the Adviser and any Affiliated Fund Services Provider, if the engagement related directly to the Fund’s operations and financial reporting (except for those subject to the pre-approval exception described above). The Audit Committee requested and received information from KPMG LLP about any non-audit services that KPMG LLP rendered during the Fund’s last fiscal year to the Adviser and any Affiliated Fund Service Provider. The Committee considered this information in evaluating KPMG LLP’s independence.

Item 8(a)(1). PORTFOLIO MANAGER BIOGRAPHIES

John V. Miller, CFA, serves as the head of Nuveen Municipals for Nuveen Asset Management, responsible for the investment process and performance of the firm’s municipal fixed income group. He is also the lead manager of the High Yield Municipal Bond Strategy, the California High Yield Municipal Bond Strategy, and related institutional portfolios.

POTENTIAL MATERIAL CONFLICTS OF INTEREST

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for a Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by a portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.
Conflicts of interest may also arise when the Sub-Adviser invests one or more of its client accounts in different or multiple parts of the same issuer’s capital structure, including investments in public versus private securities, debt versus equity, or senior versus junior/subordinated debt, or otherwise where there are different or inconsistent rights or benefits. Decisions or actions such as investing, trading, proxy voting, exercising, waiving or amending rights or covenants, workout activity, or serving on a board, committee or other involvement in governance may result in conflicts of interest between clients holding different securities or investments. Generally, individual portfolio managers will seek to act in a manner that they believe serves the best interest of the accounts they manage. In cases where a portfolio manager or team faces a conflict among its client accounts, it will seek to act in a manner that it believes best reflects its overall fiduciary duty, which may result in relative advantages or disadvantages for particular accounts.
Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Item 8(a)(3). FUND MANAGER COMPENSATION

As of the most recently completed fiscal year end, the primary portfolio manager’s compensation is as follows:
Portfolio managers are compensated through a combination of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.
Base salary. A portfolio manager’s base salary is determined based upon an analysis of the portfolio manager’s general performance, experience and market levels of base pay for such position.
Cash bonus. A portfolio manager is eligible to receive an annual cash bonus that is based on three variables: risk-adjusted investment performance relative to benchmark generally measured over the most recent three and five year periods (unless the portfolio manager’s tenure is shorter), ranking versus Morningstar peer funds generally measured over the most recent three and five year periods (unless the portfolio manager’s tenure is shorter), and management and peer reviews.
Long-term performance award. A portfolio manager is eligible to receive a long-term performance award that vests after three years. The amount of the award when granted is based on the same factors used in determining the cash bonus. The value of the award at the completion of the three-year vesting period is adjusted based on the risk-adjusted investment performance of Fund(s) managed by the portfolio manager during the vesting period and the performance of the TIAA organization as a whole.
Profits interest plan. Portfolio managers are eligible to receive profits interests in Nuveen Asset Management and its affiliate, Teachers Advisors, LLC, which vest over time and entitle their holders to a percentage of the firms’ annual profits. Profits interests are allocated to each portfolio manager based on such person’s overall contribution to the firms.

There are generally no differences between the methods used to determine compensation with respect to the Fund and the Other Accounts shown in the table above.
