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.
A renewed increase in COVID-19 cases in multiple areas, including an outbreak affecting President Trump and White House staffers and contacts, showed that controlling the spread of the novel coronavirus remains an ongoing public health concern as economies reopen and social activities resume. In the meantime, medical knowledge is improving and some areas have been able to implement much narrower restrictions when infection clusters have recurred. This, along with government stimulus, has helped an economic recovery gain traction, with a significant recovery in jobs, consumer spending, manufacturing and other indicators from their weakest levels. Additionally, progress toward a vaccine and treatments has been promising, while the timeline is unknown. Markets have recently taken an optimistic view, but the course of the virus and policy goals of the presumptive Biden administration – and their implications for the U.S. economic recovery – will continue to shape sentiment.
While we do not want to understate the dampening effect on the global economy, it is important to differentiate short-term interruptions from the longer-lasting implications to the economy. Prior to the COVID-19 crisis, some areas of the global economy were showing signs of improvement after trade tensions had weighed on economic activity for much of 2019. More recently, countries that have reopened have seen marked improvement in some near-term economic indicators.
Central banks and governments around the world have announced economic stimulus measures and pledged to continue doing what it takes to support their economies. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced similar programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. Government has approved three relief packages, including a $2 trillion-dollar package directly supporting businesses and individuals. The Coronavirus Aid, Relief and Economic Security Act, called the CARES Act, has provided direct payments and expanded unemployment benefits to individuals, loans and grants to small businesses, loans and other money to large corporations and funding for hospitals, public health, education and state and local governments. Additional stimulus measures are expected after the election, even if control of Congress remains divided. In the European Union, the European Central Bank recently increased the size of its Pandemic Emergency Purchase Program, known as PEPP, to $1.6 trillion from $882 billion and extended its duration to June 2021.
In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial professional, who can review your time horizon, risk tolerance and investment goals. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.
Sincerely,
Terence J. Toth
Chair of the Board
November 20, 2020

Portfolio Manager’s Comments
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 key investment strategies and the six-month performance of the Nuveen Select Maturities Municipal Fund (NIM). Paul has managed NIM since 2006.
An Update on COVID-19 Coronavirus and its Impact on the Securities Markets
Slowing COVID-19 coronavirus infection rates around the world encouraged authorities to loosen restrictions on business and social activity in recent months. While economic indicators have improved considerably from the depths of the shutdown, some regions, including the U.S. and Europe, have seen an uptick in infection rates after reopening, which prompted tightening coron-avirus restrictions in some areas. Additionally, certain government programs supporting businesses and workers are expiring with little clarity on extensions or replacement options. Amid these challenges, the pace of recovery appeared to be moderating and short-term market volatility has picked up again.
The initial market response was severe, but the responses from central banks and governments to ease the strain on financial systems, businesses and individuals, as well as positive vaccine news, have helped markets bounce back from the depths of the crisis. Although the detection of the virus in China was made public in December 2019, markets did not start to fully acknowledge the risks and potential economic impact until the latter portion of February 2020, when outbreaks outside of China were first reported. Global stock markets sold off severely, with the S&P 500® index reaching a bear market (a 20% drop from the previous high) within three weeks, the fastest bear market decline in history. Even certain parts of the bond market suffered; below investment grade municipal and corporate bonds generally dropped the furthest, mostly out of concerns for the continued financial stability of lower quality issuers. Demand for safe-haven assets, along with mounting recession fears, drove the yield on the 10-year U.S. Treasury note to 0.5% in March 2020, an all-time low. Additionally, oil prices collapsed to an 18-year low on supply glut concerns, as shutdowns across the global economy sharply reduced oil demand, although oil prices have recovered to well above those lows.
While most markets have recovered most of their losses, volatility will likely remain elevated until the health crisis itself is under control (via fewer new cases, lower infection rates and/or verified treatments or vaccines). There are still many unknowns and new information is incoming daily, compounding the difficulty of modeling outcomes for epidemiologists and economists alike.

Portfolio Manager’s Comments (continued)
Nuveen, LLC and our portfolio management teams are monitoring the situation carefully and continuously refining our views and approaches to managing the Funds to best pursue investment objectives while mitigating risks through all market environments.
What key strategies were used to manage NIM during the six-month reporting period ended September 30, 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. The Fund may use inverse floating rate securities (or tender option bond financing) to more efficiently implement its investment strategy to create up to 10% effective leverage.
During the six-month reporting period, the municipal market continued to recover from the liquidity-driven sell-off in March 2020 (prior to the beginning of this reporting period). As the economic shock caused by COVID-19 containment measures was becoming apparent in March 2020, financial markets including U.S. municipal bonds responded dramatically. Interest rate volatility spiked, municipal bond prices severely dislocated from Treasury bond prices and municipal credit spreads widened to levels significantly above the long-term average. Quick intervention from the government and Federal Reserve (Fed) brought stability to the municipal market, supporting a rebound in the high grade segments of the municipal bond market. Lower rated, higher yielding municipal bonds, however, were slower to rebound, as these credits are more typically found in sectors more affected by the COVID-19 crisis, including transportation, lodging, convention centers, hospitals, senior living facilities and higher education.
Despite the elevated volatility in March and April 2020, interest rates ended the six-month reporting period down slightly from the beginning of the reporting period. A sharper fall in short-term rates, driven by the Fed moving its benchmark target rate to zero, steepened the yield curve. Demand for municipal bonds began to recover, with investor inflows resuming a positive trend after the March-April sell-off, including in high yield municipal bonds. Issuance also approached more normal levels by the end of the reporting period. Notably, taxable municipal bonds’ share of issuance has risen meaningfully over the past year, which has increased the scarcity value of tax-exempt municipal bonds. Supply-demand conditions have therefore remained favorable for municipal bonds, helping credit spreads to narrow from the widest levels seen during the pandemic-induced volatility.
Our trading activity, which was largely driven by the reinvestment of call and maturity proceeds, continued to focus on pursuing the Fund’s investment objectives. 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. Additionally, as a closed end fund, the Fund does not need to sell positions to meet investor redemptions. The Fund’s ability to reinvest cash inflows was beneficial in this period of market weakness, when buying opportunities were more abundant. To maintain the Fund’s target range of 8 to 12 years, we bought bonds with an average maturity of 9 years, while the average maturity of bond redemptions was 4 years. We added bonds across a diverse range of sectors and credit ratings, although quality skewed toward medium investment grade. Names we bought included CommonSpirit Health, Parkview Medical Center, Puerto Rico sales tax revenue bonds (known as COFINAs), MTA (Metropolitan Transportation Authority) in New York, NuStar, Tower Health, Altru Health, NRG Energy and MaineGeneral Health. The Fund’s allocation to housing bonds increased, with the purchase of housing issues for Nebraska, Wisconsin, New York, Alabama and Pennsylvania. The allocation to pre-refunded bonds increased passively, due to refunding activity during the reporting period.
How did NIM perform during the six-month reporting period ended September 30, 2020?
The table in NIM’s Performance Overview and Holding Summaries section of this report provides total returns for the Fund for the six-month, one-year, five-year and ten-year periods ended September 30, 2020. The Fund’s returns are compared with the performance of corresponding market indexes.
For the six months ended September 30, 2020, the total return on net asset value (NAV) for NIM outperformed the return for the S&P Municipal Bond Intermediate Index.

Although the falling interest rate environment during the reporting period was generally beneficial for Fund performance, the Fund’s yield curve positioning was less favorable for the yield curve steepening that occurred. The Fund’s overweight to longer maturities (10 years and longer) was a strong positive contributor, as longer bonds outperformed. However, the Fund’s significant overweight to the shorter (zero to 2-year) maturities detracted, as shorter bonds lagged in this reporting period. As a result, duration and yield curve positioning had a somewhat negative impact on relative performance.
Credit quality and sector allocations were positive contributors to relative performance. Credit spreads narrowed substantially since March 2020, helping lower rated bonds to outperform in this reporting period. As a result, the Fund’s overweights primarily to A and BBB rated credits were a strong positive contributor. Exposure to below investment grade bonds also added to performance. On a sector basis, the top performers were overweight allocations in tobacco settlement and industrial development revenue (IDR) bonds and an underweight in utilities. Weak performing sector positions included overweight positions in the housing and health care sectors and an underweight in education. Single-family housing bonds came under pressure due to historically low mortgage rates, which have led to a significant increase in mortgage refinancing activity that shortens the expected average life of these housing bonds.
Security selection was favorable across a number of sectors, but gains were offset by negative performance from a few larger holdings that suffered event/headline-driven weakness. Brightline (formerly known as Virgin Trains USA) underperformed during the reporting period as revenues declined after the Florida high speed rail system suspended its operations during the COVID-19 crisis. The Fund’s position in Energy Harbor common stock was another large detractor. The Fund acquired shares in Energy Harbor when its holding of certain municipal bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of FirstEnergy Solution’s emergence from bankruptcy protection. The share price appreciated strongly post its March 2020 issuance, which increased both the size of the Fund’s position and its impact to performance. In July 2020, the stock suffered a correction on negative headline news about the predecessor company and its former parent company. While we continue to closely monitor the situation, we believe that the sell-off was a short-term overreaction and that over the long term, the company’s underlying value will be recognized by the market. Other detractors included our security selection in tobacco settlement bonds (due to holdings in D.C. and Illinois) and education (due to student loan credits). However, our security selection outperformed in utilities (especially prepay gas credits), tax supported (Chicago Board of Education, Chicago debt, New Jersey debt and Puerto Rico COFINAs), transportation (both airports and toll roads) and housing (primarily due to longer duration housing bonds).

Common Share Information
COMMON SHARE DISTRIBUTION INFORMATION
The following information regarding the Fund’s distributions is current as of September 30, 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.

Yields

Taxable-Equivalent Yield* 
5.11% 
 
*     
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.

(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.

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) 
 
divided by the average long-term market value during the period.

Notes to
Financial Statements (Unaudited)

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 September 30, 2020, and the period covered by these Notes to Financial Statements is the six months ended September 30, 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. 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 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.
40


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 is recorded on an accrual basis and includes accretion of discounts and amortization of premiums for financial reporting purposes. Investment income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash. Investment income also reflects dividend income, which 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
Reference Rate Reform
In March 2020, FASB issued Accounting Standards Update (“ASU”) 2020-4, 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 optional expedients of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the optional expedients, but is currently assessing the impact of the ASU’s adoption to the Funds’ financial statements and various filings.
3. Investment Valuation and Fair Value Measurements
The Fund’s investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. U.S. GAAP establishes the three-tier hierarchy which is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect management’s assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.
Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.
Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).
Level 3 – Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).
A description of the valuation techniques applied to the Fund’s major classifications of assets and liabilities measured at fair value follows:
Prices of fixed-income securities are generally provided by an independent pricing service (“pricing service”) approved by the Board. The pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity, provided by the Adviser. These securities are generally classified as Level 2.
Equity securities and exchange-traded funds listed or traded on a national market or exchange are valued based on their sale price at the official close of business of such market or exchange on the valuation date. Foreign equity securities are valued at the last sale price or official closing price reported on the exchange where traded and converted to U.S. dollars at the prevailing rates of exchange on the date of valuation. To the extent these securities
41
 

Notes to Financial Statements (Unaudited) (continued)
are actively traded and that valuation adjustments are not applied, they are generally classified as Level 1. If there is no official close of business, then the latest available sale price is utilized. If no sales are reported, then the mean of the latest available bid and ask prices is utilized and are generally classified as Level 2.
Any portfolio security or derivative for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued at fair value, as determined in good faith using procedures approved by the Board. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be 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. To the extent the inputs are observable and timely, the values would be classified as Level 2 of the fair value hierarchy; otherwise they would be classified as Level 3.
The following table summarizes the market value of the Fund’s investments as of the end of the reporting period, based on the inputs used to value them:

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 $11,096,466 and $9,413,120, 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.
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.
42
 

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 September 30, 2020.
   
Tax cost of investments 
$123,575,882 
Gross unrealized: 
 
Appreciation 
$ 9,622,768 
Depreciation 
(867,651) 
Net unrealized appreciation (depreciation) of investments 
$ 8,755,117 
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 last tax year end.
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 last 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.
43


Notes to Financial Statements (Unaudited) (continued)
The tax character of distributions paid during the Fund’s last tax year ended March 31, 2020 was designated for purposes of the dividends paid deduction as follows:
   
Distributions from net tax-exempt income 
$3,941,569 
Distributions from net ordinary income2 
16,056 
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. 
 
During the Fund’s last 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     
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, but do 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 September 30, 2020, the complex- level fee for each Fund was 0.1575%.
44
 
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 engaged in cross-trades pursuant to these procedures as follows: 
 

Cross-Trades 
 
Purchases 
$500,000 
Sales 
500,000 
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, $2.405 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 multifactor 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 2021 unless extended or renewed.
The credit facility has the following terms: a 0.10% upfront fee, 0.15% per annum on unused commitment amounts and a drawn interest rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.25% (1.00% prior to June 24, 2020) per annum or (b) the Fed Funds rate plus 1.25% (1.00% prior to June 24, 2020) per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of ‘‘Interest expense’’ 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.

Shareholder Update (Unaudited)
Changes Occurring During the Reporting Period
The following information in this semi-annual report is a summary of certain changes during the reporting period. This information may not reflect all of the changes that have occurred since you purchased shares of the Fund.
Amended and Restated By-Laws
On October 5, 2020, after a rigorous and deliberative review, and consistent with the interests of the Fund’s long-term shareholders, the Board of Trustees of the Fund adopted Amended and Restated By-Laws.
Among other changes, the Amended and Restated By-Laws require compliance with certain amended deadlines and procedural and informational requirements in connection with advance notice of shareholder proposals or nominations, including certain information about the proponent and the proposal, or in the case of a nomination, the nominee. Any shareholder considering making a nomination or other proposal should carefully review and comply with those provisions of the Amended and Restated By-Laws.
The Amended and Restated By-Laws also include provisions (the “Control Share By-Law”) pursuant to which, in summary, a shareholder who obtains beneficial ownership of common shares of the Fund in a “Control Share Acquisition” may exercise voting rights with respect to such shares only to the extent the authorization of such voting rights is approved by other shareholders of the Fund. The Control Share By-Law is primarily intended to protect the interests of the Fund and its long-term shareholders by limiting the risk that the Fund will become subject to undue influence by opportunistic traders pursuing short-term agendas adverse to the best interests of the Fund and its long-term shareholders. The Control Share By-Law does not eliminate voting rights for common shares acquired in Control Share Acquisitions, but rather entrusts the Fund’s other “non-interested” shareholders with determining whether to approve the authorization of the voting rights of the person acquiring such shares.
Subject to various conditions and exceptions, the Control Share By-Law defines a “Control Share Acquisition” to include an acquisition of common shares that, but for the Control Share By-Law, would give the beneficial owner, upon the acquisition of such shares, the ability to exercise voting power in the election of Trustees of the Fund in any of the following ranges:
 
(i)     
one-tenth or more, but less than one-fifth of all voting power;
 
(ii)     
one-fifth or more, but less than one-third of all voting power;
 
(iii)     
one-third or more, but less than a majority of all voting power; or
 
(iv)     
a majority or more of all voting power.
The Control Share By-Law generally excludes certain acquisitions of common shares from the definition of a Control Share Acquisition, including acquisitions of common shares that occurred prior to October 5, 2020, though such shares are included in assessing whether any subsequent share acquisition exceeds one of the enumerated thresholds.
Subject to certain conditions and procedural requirements set forth in the Control Share By-Law, including the delivery of a “Control Share Acquisition Statement” to the Fund’s Secretary setting forth certain required information, a shareholder who obtains or proposes to obtain beneficial ownership of common shares in a Control Share Acquisition generally may demand a special meeting of shareholders for the purpose of considering whether the voting rights of such acquiring person with respect to such shares shall be authorized.
This discussion is only a high-level summary of certain aspects of the Amended and Restated By-Laws, and is qualified in its entirety by reference to the Amended and Restated By-Laws. Shareholders should refer to the Amended and Restated By-Laws for more information. A copy of the Amended and Restated By-Laws can be found in the Current Report on Form 8-K filed by the Fund with the Securities and Exchange Commission on October 6, 2020, which is available at www.sec.gov, and may also be obtained by writing to the Secretary of the Fund at 333 West Wacker Drive, Chicago, Illinois 60606.

Glossary of Terms Used in this Report
■    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.
■    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.

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 the investment sub-adviser 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.
50
 

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,

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
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;
52
 

•     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 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-, three- and five-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.
53

 

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
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 although the Fund ranked in the fourth quartile of its Performance Peer Group for the one-year period ended December 31, 2019, the Fund ranked in the third quartile of its Performance Peer Group for the three- and five-year periods ended December 31, 2019. The Fund also outperformed its benchmark for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund’s performance was below the performance of its benchmark and the Fund ranked in the third quartile of its Performance Peer Group for the one-, three- and five-year periods ended March 31, 2020. In its review, the Board, however, noted that the Performance Peer Group was classified as low for relevancy. The Board was satisfied with the Fund’s overall performance.
54
 

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 Nuveen fund to the Adviser in light of the nature, extent and quality of the services provided. The Board also considered the total operating expense ratio of each Nuveen 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 Nuveen 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”), including the 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 that were higher than its respective peer averages. The Independent Board Members noted that the Fund’s net expense ratio was higher than the average of the Peer Universe primarily due to the odd composition of the Peer Universe which contained only one non-Nuveen fund. The Independent Board Members noted that the Fund’s net management fee and net expense ratio were below those of the non-Nuveen peer. The Independent Board Members were satisfied with the explanation of the differential.
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 were higher in 2019 than the previous year and considered the key drivers behind the revenue and expense changes that
56
 

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
57

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 its 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.
