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 all whose lives have been affected by the disease and its economic fallout. The extreme “social distancing” efforts needed to contain the coronavirus are causing a severe contraction in economic activity and amplifying market volatility, as global supply chains and consumer and business demand have been significantly disrupted. With some regions of the world having appeared to “flatten the curve” of infections, governments and public health officials face the extraordinary challenge of balancing the resumption of economic activity with public safety, in a way that minimizes the potential for a second wave of outbreaks. The spike in market volatility during March and the strong rally that followed in April may be indicative of the large swings in both directions that are likely to continue as markets digest new information and seek more clarity.

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. Some areas of the global economy were already on the mend prior to the coronavirus epidemic. Momentum could pick up again as factories come back online and consumer demand resumes once the virus is under control and temporary bans on movement and travel are lifted. Central banks and governments around the world have announced economic stimulus measures. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced 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. Additional aid will likely be approved in the months ahead.

In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial advisor, who can review your time horizon, risk tolerance and investment goals. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Sincerely,

Terence J. Toth
Chair of the Board

Nuveen Select Maturities Municipal Fund (NIM)

This Fund features portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen Fund Advisors, LLC, the Fund’s investment adviser. Portfolio manager Paul L. Brennan, CFA, reviews U.S. economic and municipal market conditions, key investment strategies and the twelve-month performance of the Nuveen Select Maturities Municipal Fund (NIM). Paul has managed NIM since 2006.

What factors affected the U.S. economy and the national municipal market during the twelve-month reporting period ended March 31, 2020?

The longest economic expansion in U.S. history came to an abrupt halt in early 2020 amid the 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 (as of the end of March 2020). The disruption has been swift and severe, and is expected to tip the economy into recession, a several months’ long contraction across the broad economy. For the first quarter of 2020, the Bureau of Economic Analysis reported that annualized gross domestic product (GDP) shrank 4.8%, according to its “advance” estimate. GDP measures the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes. 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 coronavirus containment measures drove a significant drop in consumer spending and a sharp rise in unemployment in the final month of the quarter. The Bureau of Labor Statistics said the unemployment rate rose to 4.4% in March 2020 from 3.8% in March 2019 and job gains averaged around 118,000 per month for the past twelve months, as the economy lost 701,000 jobs in March 2020. Average hourly earnings grew at an annualized rate of 3.1% in March 2020. However, the overall trend of inflation remained subdued, and registered a notably slower rate in March 2020 due to falling gasoline prices. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 1.5% over the twelve-month reporting period ended March 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 yet 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 4.2% year-over-year in February 2020 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 2.9% and 3.5%, respectively.

Portfolio Manager’s Comments (continued)

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

While trade and tariff policy drove market sentiment for most of the twelve-month reporting period, the outbreak of the novel coronavirus and its associated disease COVID-19 rapidly dwarfed all other market concerns as the reporting period was closing. Equity and commodity markets sold-off and safe-haven assets rallied 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.

Prior to the virus outbreak, 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 European Union (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.

Investors also remained watchful of local political dynamics around the world. In the U.K., the Conservative Party won a large majority in the December 2019 general election and Parliament passed the Brexit Bill days later, facilitating the U.K.’s exit from the EU at the end of January 2020. In Italy, the prime minister unexpectedly resigned in August 2019, and the newly formed coalition government appeared to take a less antagonistic stance towards the EU. Europe’s traditional centrist parties lost seats in the May 2019 Parliamentary elections and populist parties saw marginal gains. Europe also contended with the “yellow vest” protests in France, immigration policy concerns, Russian sanctions and political risk in Turkey. Anti-government protests erupted across Latin America, Hong Kong and Lebanon during 2019. Venezuela’s economic and political crisis deepened. Argentina surprised the market with the return of a less market-friendly administration. Brazil’s Bolsonaro administration achieved a legislative win on pension reform and kept the economy on a path of modest growth. The ruling parties in India and South Africa maintained their majorities, where slower economic growth could complicate their respective reform mandates.

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, 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. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. In the final weeks of the reporting period, monetary and fiscal interventions from the Fed and U.S. government helped the market stabilize, although prices remained meaningfully off their pre-crisis levels. The U.S. Treasury yield curve flattened overall, with a portion of the curve temporarily inverting (i.e. longer rates were lower than shorter rates, the opposite of normal) from late August 2019 to late September 2019. The municipal yield curve also flattened overall during the reporting period, as yields on longer maturities fell more than those of shorter maturities.

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 increased meaningfully in 2019. The Tax Cut and Jobs Act of 2017 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 and the strong demand for yield to issue taxable municipal debt, enabling them to save on net interest costs.

Demand for municipal bonds was strong for most of this reporting period. Municipal bond funds took in consistently positive cash flows in calendar year 2019 and the first two months of 2020. However, fund flows turned more volatile in March 2020, as markets began to digest the coronavirus impact. Low interest rates in the U.S. and globally have continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have begun to assess the impact of 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 in 2019 to date, especially in states with high income taxes and/or property taxes.

What key strategies were used to manage NIM during the twelve-month reporting period ended March 31, 2020?

The Fund’s primary investment objective is current income exempt from regular federal income tax, consistent with the preservation of capital. Its secondary objective is the enhancement of portfolio value. The Fund invests in municipal securities that are exempt from federal income taxes. The Fund invests in municipal securities of varying maturities targeting an overall intermediate duration profile.

For most of the reporting period, a favorable macroeconomic backdrop, strong demand, narrowing credit spreads and falling interest rates supported municipal bond performance. However, the coronavirus pandemic and the shutdown of the economy introduced significant uncertainty about the future of economic growth and impact to municipal credit fundamentals. As the nearer-term impacts began to materialize, we looked for relative value and income enhancement opportunities among credits we believe may demonstrate resilience over the long term.

With its emphasis on intermediate maturities, lower rated credits and sectors offering higher yields, we considered the Fund generally well positioned for the more normal market conditions present in the majority of the reporting period. The Fund’s overall positioning remained relatively unchanged during the reporting period, although we allowed its duration to drift toward the shorter end of its target range. In the prevailing market conditions before the health crisis, there were fewer opportunities to source enhanced income among longer duration bonds.

We continued to seek attractive relative value opportunities to bolster the Fund’s long-term performance potential. We bought bonds across a range of sectors and selectively added different maturity structures, including single-family housing bonds and new issues for CommonSpirit Health and New York MTA (Metropolitan Transportation Authority). We also added high yield, below investment grade rated credits issued for Puerto Rico sales tax revenue (known as COFINAs), Puerto Rico Aqueduct and Sewer

Portfolio Manager’s Comments (continued)

Authority (PRASA) and Virgin Trains USA Passenger Rail Project, a privately operated South Florida rail line. The Virgin Trains USA credits were issued after Brightline Passenger Rail Project called some bonds, which we owned, and was subsequently renamed Virgin Trains USA. We also bought the replacement Buckeye Tobacco settlement bonds. During the reporting period, the state of Ohio refinanced its legacy tobacco settlement bonds, which we owned, and issued new bonds with a higher quality rating than the old bonds.

The proceeds from called and maturing bonds provided most of the cash to invest in new bonds. Because NIM is an intermediate maturity Fund, it typically has a greater number of bonds maturing or being called than funds with longer average maturity targets. Our trading activity was mostly driven by reinvesting these proceeds, as we believed the Fund was well positioned to meet its income and maturity mandates.

In addition, NIM now holds Energy Harbor common stock, after FirstEnergy Solutions successfully 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. Over time, we expect to sell these shares and reinvest the proceeds into municipal bonds.

How did NIM perform during the twelve-month reporting period ended March 31, 2020?

The table in NIM’s Performance Overview and Holding Summaries section of this report provides total returns for the Fund for the one-year, five-year and ten-year periods ended March 31, 2020. The Fund’s returns are compared with the performance of corresponding market indexes.

For the twelve months ended March 31, 2020, the total return on net asset value (NAV) for NIM underperformed the return for the S&P Municipal Bond Intermediate Index.

The speed and severity of the March 2020 sell-off had a significant impact on performance for the 12-month period overall. The main drag on relative performance came from the disproportionate credit spread widening among lower rated and high yield bonds during March 2020. The Fund’s exposure to credits rated BBB and lower, including tobacco, utilities and tax supported Puerto Rico bonds, were hit particularly hard in March 2020, overwhelming the strong performance generated earlier in the reporting period. Lower rated investment grade bonds, such as the Buckeye Tobacco replacement bonds we bought, also declined, albeit to a lesser extent than the BBB rated and below investment grade bonds.

The Fund’s positioning was modestly favorable in the sectors predominantly composed of higher grade bonds, including pre-refunded, single-family housing and local general obligation (GO) bonds. The Fund held a slight overweight to pre-refunded bonds, as we held onto the bonds to keep the portfolio fully invested and earn income while waiting for more attractive long-term opportunities. The Fund’s holdings in local GOs benefited from their longer durations as well as higher credit quality.

The Fund’s relatively shorter duration than the benchmark was a mild relative detractor in this reporting period, as the Fund did not fully benefit from the decline in interest rates. However, the Fund’s small overweight in longer duration bonds was modestly helpful.

Common Share Information

COMMON SHARE DISTRIBUTION INFORMATION

The following information regarding the Fund’s distributions is current as of March 31, 2020. The Fund’s distribution levels may vary over time based on its investment activity and portfolio investment value changes.

During the current reporting period, the Fund’s distributions to common shareholders were as shown in the accompanying table.

	Per Common
Monthly Distributions (Ex-Dividend Date)	Share Amounts
April 2019	$0.0265
May	0.0265
June	0.0265
July	0.0265
August	0.0265
September	0.0265
October	0.0265
November	0.0265
December	0.0265
January	0.0265
February	0.0265
March 2020	0.0265
Total Distributions from Net Investment Income	$0.3180
Yields
Market Yield*	3.25%
Taxable-Equivalent Yield*	5.49%

Market Yield is based on the Fund’s current annualized monthly distribution 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 an income tax rate of 40.8%. When comparing the Fund to investments that generate qualified dividend income, the Taxable-Equivalent Yield would be lower. 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 either exempt from federal income tax but not from state income tax (e.g., income from an out-of-state municipal bond), or was exempt from neither federal nor state 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 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.

Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.

(4) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.

(a)	Total Return Based on Common Share NAV is the combination of changes in NAV, reinvested dividend income at Common Share NAV and reinvested capital gains distri- butions 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)	Portfolio Turnover Rate is calculated based on the lesser of long-term purchases or sales (as disclosed in Note 4 – Portfolio Securities and Investments in Derivatives, Investment Transactions) divided by the average long-term market value during the period.
*	Rounds to less than $0.01 per share.

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 Select Maturities Municipal Fund (NIM) (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 July 23, 1992.

The end of the reporting period for the Fund is March 31, 2020, and the period covered by these Notes to Financial Statements is the fiscal year ended March 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 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. There have been no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have on the Fund’s financial performance. 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 Principles

The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. Each Fund is an investment company and follows the accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services — Investment Companies. The net asset value (“NAV”) for financial reporting purposes may differ from the NAV for processing security and 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.

Table of Contents

Investments and Investment Income

Securities transactions are accounted for as of the trade date for financial reporting purposes. 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. Investment income also reflects payment-in-kind (“PIK”) interest and fee income, if any. PIK interest represents income received in the form of securities in lieu of cash. Dividend income is recorded on the ex-dividend date.

Netting Agreements

In the ordinary course of business, the Fund may enter into transactions subject to enforceable International Swaps and Derivative 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 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. In addition, derivative contracts that qualified for hedge accounting prior to modification, will be allowed to continue to receive such treatment, even if critical terms change due to a change in the benchmark interest rate. For new and existing contracts, the Funds may elect to apply the amendments as of March 12, 2020 through December 31, 2022. Management 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 spreads, etc.).

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

Table of Contents

Notes to Financial Statements (continued)

Prices of fixed income securities are provided by an independent pricing service (“pricing service”) approved by the Board. The pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity, provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs.

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:

	Level 1		Level 2			Level 3		Total
Long-Term Investments:
Municipal Bonds*	$	—	$	124,358,325		$	—	$	124,358,325
Common Stocks		—		1,483,476	**		—		1,483,476
Short-Term Investments:

Total	$	—	$	127,341,515		$	—	$	127,341,515

*	Refer to the Fund’s Portfolio of Investments for state classifications.
**	Refer to the Fund’s Portfolio of Investments for securities classified as Level 2.

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 aggregated $16,919,273 and $16,973,220, respectively.

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.

Table of Contents

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

The Fund did not have any share transactions during the current and prior fiscal period.

6. Income Tax Information

The Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Furthermore, the Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal and designated state income taxes, 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.

The table below presents the cost and unrealized appreciation (depreciation) of the Fund’s investment portfolio, as determined on a federal income tax basis, as of March 31, 2020.

Tax cost of investments	$	122,281,614
Gross unrealized:
Appreciation	$	6,744,087
Depreciation		(1,684,186	)
Net unrealized appreciation (depreciation) of investments	$	5,059,901

Permanent differences, primarily due to taxable market discount and paydowns, resulted in reclassifications among the Fund’s components of common shares net assets as of March 31, 2020, the Fund’s tax year end.

Table of Contents

Notes to Financial Statements (continued)

The tax components of undistributed net tax-exempt income, net ordinary income and net long-term capital gains as of March 31, 2020, the Fund’s tax year end, were as follows:

Undistributed net tax-exempt income¹	$	513,603
Undistributed net ordinary income²		79,468
Undistributed net long-term capital gains		587,717

¹	Undistributed net tax-exempt income (on a tax basis) has not been reduced for the dividend declared on March 2, 2020, paid on April 1, 2020.
²	Net ordinary income consists of taxable market discount income and net short-term capital gains, if any.

The tax character of distributions paid during the Fund’s tax years ended March 31, 2020 and March 31, 2019 was designated for purposes of the dividends paid deduction as follows:

2020
Distributions from net tax-exempt income³	$	3,941,569
Distributions from net ordinary income²		16,056
Distributions from net long-term capital gains		—
2019
Distributions from net tax-exempt income	$	3,867,601
Distributions from net ordinary income²		52,688
Distributions from net long-term capital gains		—

²	Net ordinary income consists of taxable market discount income and net short-term capital gains, if any.
³	The Fund hereby designates these amounts paid during the fiscal year ended March 31, 2020, as Exempt Interest Dividends.

During the Fund’s tax year ended March 31, 2020, the Fund utilized $63,555 of capital loss carryforwards.

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.

The annual fund-level fee, payable monthly, is calculated according to the following schedule:

Average Daily Net Assets*	Fund-Level Fee Rate
For the first $125 million		0.3000	%
For the next $125 million		0.2875
For the next $250 million		0.2750
For the next $500 million		0.2625
For the next $1 billion		0.2500
For the next $3 billion		0.2250
For managed assets over $5 billion		0.2125

Table of Contents

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 net assets:

Complex-Level Eligible Asset Breakpoint Level*	Effective Complex-Level Fee Rate at Breakpoint Level
$55 billion	0.2000%
$56 billion	0.1996
$57 billion	0.1989
$60 billion	0.1961
$63 billion	0.1931
$66 billion	0.1900
$71 billion	0.1851
$76 billion	0.1806
$80 billion	0.1773
$91 billion	0.1691
$125 billion	0.1599
$200 billion	0.1505
$250 billion	0.1469
$300 billion	0.1445

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 funds’ 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 closed-end Funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen funds or 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. As of March 31, 2020, the complex-level fee rate for the Fund was 0.1590%.

Other Transactions with Affiliates

The Fund is permitted to purchase or sell securities from or to certain other funds managed by the Adviser (“inter-fund trade”) under specified conditions outlined in procedures adopted by the Board. These procedures have been designed to ensure that any inter-fund trade of securities by the Fund from or to another fund that is, or could be, considered an affiliate of the Fund under certain limited circumstances by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 of the 1940 Act. Further, as defined under these procedures, each inter-fund trade is effected at the current market price as provided by an independent pricing service. Unsettled inter-fund trades as of the end of the reporting period are recognized as a component of “Receivable for investments sold” and/or “Payable for investments purchased” on the Statement of Assets and Liabilities, when applicable.

During the current fiscal period, the Fund did not engage in inter-fund 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. A large portion of this facility’s capacity (and its associated costs as described below) is currently dedicated for use by a small number of Participating Funds, which does not include the Fund covered by this shareholder report. The credit facility expires in June 2020 unless extended or renewed.

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.

Utilization period (days outstanding)	2
Average daily balance outstanding	716,009
Average annual interest rate	2.76%

Borrowings outstanding as of the end of the reporting period are recognized as “Borrowings” on the Statement of Assets and Liabilities, where applicable.

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.

Table of Contents

Glossary of Terms Used in this Report (Unaudited)

■ Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have “failed,” with current holders receiving a formula-based interest rate until the next scheduled auction.

■ 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.

■ 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.

■ 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.

■ S&P Municipal Bond Intermediate Index: An unleveraged, market value-weighted index containing all of the bonds in the S&P Municipal Bond Index with maturity dates between 3 and 14.999 years. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

■ 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.
