0001090116 false A maximum sales charge of 1.00% applies only to offerings made at-the-market. There is no sales charge for offerings pursuant to an underwritten transaction or a private transaction. You will be charged a $2.50 service charge and pay brokerage charges if you direct Computershare Inc. and Computershare Trust Company, N.A., as agent for the common shareholders, to sell your Common Shares held in a dividend reinvestment account. Stated as percentages of average net assets attributable to Common Shares for the fiscal year ended October 31, 2023. Interest and Other Related Expenses reflect actual expenses and fees for leverage incurred by a Fund for the fiscal year ended October 31, 2023. The types of leverage used by each Fund during the fiscal year ended October 31, 2023 are described in the Fund Leverage and the Notes to Financial Statements (Note 4 – Portfolio Securities, Note 5 – Derivative Investments, Note 6 – Fund Shares, Note 10 – Borrowings Arrangements and Reverse Repurchase Agreements) sections of this annual report. Actual Interest and Other Related Expenses incurred in the future may be higher or lower. If short-term market interest rates rise in the future, and if a Fund continues to maintain leverage, the cost of which is tied to short-term interest rates, a Fund’s interest expenses on its short-term borrowings can be expected to rise in tandem. A Fund’s use of leverage will increase the amount of management fees paid to the Fund’s adviser and sub-advisor(s). Other Expenses are based on estimated amounts for the current fiscal year. Expenses attributable to the Fund’s investments, if any, in other investment companies are currently estimated not to exceed 0.01%. Not applicable – the Fund does not incur a sales charge for offerings pursuant to an underwritten transaction as noted in Shareholder Transaction Expenses table above. Aggregate Amount Outstanding: Aggregate amount outstanding represents the liquidation preference as of the end of the relevant fiscal year and does not include any preferred shares noticed for redemption as noted on the Statement of Assets and Liabilities, where applicable. Asset Coverage Per $100,000: Asset coverage per $100,000 is calculated by subtracting the Fund’s liabilities and indebtedness not represented by senior securities from the Fund’s total assets, dividing the result by the aggregate amount of the Fund’s senior securities representing indebtedness then outstanding (if applicable), plus the aggregate of the involuntary liquidation preference of the outstanding preferred shares, if applicable, and multiplying the result by 100,000. 0001090116 2022-11-01 2023-10-31 0001090116 2023-10-31 0001090116 2022-10-31 0001090116 2021-10-31 0001090116

Chair’s Letter
to Shareholders

|  | Dear Shareholders, Financial markets spent the past year focused on the direction of inflation and whether policy makers would be able to deliver a soft landing in their economies. After more than a year and a half of interest rate increases by the U.S. Federal Reserve (Fed) and other central banks, financial conditions have tightened and inflation rates have cooled considerably. The Fed increased the target fed funds rate from near zero in March 2022 to a range of 5.25% to 5.50% as of November 2023, with pauses in June 2023, September 2023 and November 2023. But current inflation rates remain above central banks’ targets, and the trajectory from here is difficult to predict given that monetary policy acts on the economy with long and variable lags. Surprisingly, economies were relatively resilient for much of 2023. By year-end, the “most predicted recession” had yet to materialize in the U.S., while U.K. and European economic growth was just beginning to show signs of stagnation or decline. U.S. gross domestic product rose 5.2% in the third quarter of 2023, 2.1% in the second quarter of 2023 and 2.0% in the first quarter of 2023, after growing 2.1% in 2022 overall compared to 2021. Much of the growth was driven by a relatively strong jobs market, which kept consumer sentiment and spending elevated despite long-term interest rates nearing multi-year highs, a series of U.S. regional bank failures and shocks from flaring geopolitical tensions.
|  | While central banks are likely nearing the end of this interest rate hiking cycle, there are still upside risks to inflation and downside risks to the economy. Some labor market and consumer indicators are softening. Government funding and deficits remain a concern, especially as the U.S. election year gets underway. The markets will continue to try to anticipate monetary policy shifts as the Fed evaluates incoming data and adjusts its rate setting activity on a meeting-by-meeting basis. Geopolitical risks – from relations with China, to wars in Europe and the Middle East – also expand the range of outcomes from economies and markets around the world. All these uncertainties, and others, will remain sources of short-term market volatility. In this environment, Nuveen remains committed to filtering the market noise for investable opportunities that ultimately serve long-term investment objectives. Maintaining a long-term perspective is also important for investors, and we encourage you to review your time horizon, risk tolerance and investment goals with your financial professional. 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. Terence J. Toth Chair of the Board December 22, 2023

Important Notices
Fund Mergers Update for Nuveen Municipal Credit Income Fund (NZF)
Effective prior to the opening of business on April 17, 2023, Nuveen Ohio Quality Municipal Income Fund (NUO) and Nuveen Georgia Quality Municipal Income Fund (NKG) were each merged into NZF (“each a Merger”). Refer to the Notes to Financial Statements within this report for further details on the Merger.
Portfolio Manager Updates
Effective April 10, 2023, Daniel Close, CFA, and Stephen Candido, CFA, were added as portfolio managers of NMZ, NMCO and NDMO. Effective May 31, 2023, John Miller no longer serves as a portfolio manager of NMZ, NMCO and NDMO. Effective October 13, 2023, Steven Hlavin was added as a portfolio manager of NVG. Effective October 13, 2023, Kristen DeJong, CFA, was added as a portfolio manager of NZF. There were no other changes to the portfolio management of the Funds during the reporting period.
Updated Distribution Policy for NDMO
On November 29, 2023, the Funds’ Board of Trustees (the “Board”) updated the Fund’s distribution policy. Effective for distributions payable on December 29, 2023, the Fund’s distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to shareholders of its best estimate of the distribution sources at that the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’
1099-DIV
forms after the end of the year.

What factors affected the U.S. economy and market conditions during the twelve-month annual reporting period ended October 31, 2023?
The U.S. economy performed better than expected despite persistent inflationary pressure and rising interest rates during the twelve-month period ended October 31, 2023. Gross domestic product accelerated sharply in third quarter of 2023 to an annualized rate of 5.2%, according to the U.S. Bureau of Economic Analysis second estimate, up from 2.1% in the second quarter of 2023. By comparison, GDP grew 2.1% in 2022 overall. Early in the reporting period, inflation had risen sharply because of supply chain disruptions and high food and energy prices, the Russia-Ukraine war and China’s
zero-COVID
restrictions (lifted in December 2022). Since then, price pressures have eased given normalization in supply chains, falling energy prices and aggressive measures by the U.S. Federal Reserve (Fed) and other global central banks to tighten financial conditions and slow demand in their economies. Nevertheless, during the reporting period inflation levels remained much higher than central banks’ target levels.
The Fed raised its target fed funds rate six times during the reporting period, bringing it to a range of 5.25% to 5.50% as of July 2023 and voting to hold it at that level at its next two meetings held near the end of the reporting period. For much of the reporting period, the Fed’s activity led to significant volatility in bond and stock markets, given the uncertainty of how rising interest rates would affect the economy. One of the most highly visible impacts occurred in the U.S. regional banking sector in March 2023, when Silicon Valley Bank, Signature Bank, First Republic Bank and Silvergate Bank failed. In the same month, Swiss bank UBS agreed to buy Credit Suisse, which was considered vulnerable in the current environment. The Fed’s monetary tightening policy also contributed to an increase in the U.S. dollar’s value relative to major world currencies, which acts as a headwind to the profits of international companies and U.S. domestic companies with overseas earnings.
During the reporting period, elevated inflation and higher borrowing costs weighed on some segments of the economy, including the real estate market. Consumer spending, however, has remained more resilient than expected, in part because of a still-strong labor market, another key gauge of the economy’s health. As of October 2023, the unemployment rate was 3.9%, rising from its
pre-pandemic
low, with monthly job growth continuing to moderate. The strong labor market and wage gains helped the U.S. economy during the reporting period, even as the Fed sought to soften job growth to help curb inflation pressures.
During the reporting period, investors also continued to monitor government funding and deficits. The U.S. government avoided a default scenario after approving an increase to the debt ceiling limit in June 2023. At the same time, the potential for a government shutdown loomed but was ultimately avoided with funding resolutions passed in September 2023 and, subsequent to the close

of the reporting period, November 2023. Notably, in August 2023, ratings agency Fitch downgraded U.S. debt from AAA to AA+ based on concerns about the U.S.’s growing fiscal debt and reduced confidence in fiscal management.
The broad municipal bond market was impacted by interest rate volatility and economic uncertainty during the reporting period. Municipal yields rose across the maturity spectrum, but the move was uneven. The greatest increase in yields was at the shorter end of the curve as markets priced in a more aggressive pace of monetary tightening to combat persistently high inflation. Although municipal bonds continued to exhibit relatively strong credit fundamentals, there were periods of spread widening during the reporting period as the market
sell-off
continued.
Nuveen
AMT-Free
Municipal Credit Income Fund (NVG)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NVG’s investment objectives are to provide current income exempt from regular federal income tax and federal alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market. The Fund invests in
tax-exempt
municipal bonds that the portfolio management teams believe are underrated or undervalued or that represent municipal market sectors that are undervalued and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NVG underperformed the NVG Blended Benchmark. For purposes of this Performance Commentary, references to relative performance are in comparison to the NVG Blended Benchmark, which consists of 1) 60% S&P Municipal Bond Investment Grade Index and 2) 40% S&P Municipal Bond High Yield Index.
The primary detractor from NVG’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Partially offsetting NVG’s underperformance were its underweight to shorter maturity bonds and corresponding overweight to longer maturity bonds. Additionally, the Fund’s credit quality positioning was also advantageous, as credit spreads narrowed occasionally throughout the period. The Fund continued to emphasize bonds rated
mid-investment
grade and lower, which contributed positively to relative performance.
Nuveen Municipal Credit Income Fund (NZF)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NZF’s investment objectives are to provide current income exempt from regular federal income tax and to enhance portfolio value relative to the municipal bond market. The Fund invests in
tax-exempt
municipal bonds that the portfolio management teams believe are underrated or undervalued or that represent municipal market sectors that are undervalued and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies.

Additionally, NZF continued its rotation into lower rated credit by selling AAA and AA rated bonds, which were purchased when rates were lower as temporary placeholders because of their liquidity profiles. The portfolio management team reinvested the proceeds in A, BBB and below investment grade rated bonds. As a result of this rotation strategy, the Fund’s exposures to the health care and transportation sectors increased while exposures to dedicated tax,
pre-refunded,
and water and sewer bonds decreased.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NZF underperformed the NZF Blended Benchmark. For purposes of this Performance Commentary, references to relative performance are in comparison to the NZF Blended Benchmark, which consists of 1) 60% S&P Municipal Bond Investment Grade Index and 2) 40% S&P Municipal Bond High Yield Index.
The primary detractor from NZF’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Partially offsetting NZF’s underperformance were its underweight to shorter-maturity bonds and corresponding overweight to longer maturity bonds. NZF also benefited from its overweight to the transportation sector, particularly “other transportation” bonds, which was one of the better-performing sectors during the period. The Fund’s credit quality positioning was also advantageous, as credit spreads narrowed occasionally throughout the period. Overweight allocations to mid investment grade and lower added to relative performance as these categories outperformed the highest investment grade categories.
Nuveen Municipal High Income Opportunity Fund (NMZ)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NMZ’s primary investment objective is to provide high current income exempt from regular federal income tax. Its secondary investment objective is to seek attractive total return consistent with its primary objective. NMZ invests in an actively managed portfolio of
tax-exempt
municipal securities and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies. The portfolio management team also reduced the Fund’s equity positions in American Airlines and Talen Energy (both of which were acquired in restructurings) when it was favorable to do so during the reporting period.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NMZ underperformed the S&P Municipal Yield Index. For purposes of this Performance Commentary, references to relative performance are in comparison to the S&P Municipal Yield Index.
The primary detractor from NMZ’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. However, the Fund’s use of leverage was accretive to overall common share income. Leverage is discussed in more detail in the Fund Leverage section of this report.

Portfolio Managers’ Comments
(continued)
Leading individual detractors included the Fund’s exposures to Puerto Rico Electric Power Authority (PREPA) bonds and certain project finance bonds, which faced a variety of project-specific challenges during the period. PREPA underperformed given the issuer’s ongoing restructuring. The Fund continued to hold PREPA based on the portfolio management team’s outlook.
Partial offsets to NMZ’s relative underperformance included its, credit quality positioning. Credit spreads narrowed occasionally throughout the period and the Fund benefited from an overweight to
non-rated
bonds and a corresponding underweight to the highest grade (AAA and AA rated) bonds.
Nuveen Municipal Credit Opportunities Fund (NMCO)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NMCO’s primary investment objective is to provide a high level of current income exempt from regular U.S. federal income tax and secondarily, total return. NMCO invests primarily in high yielding, low to medium-quality municipal securities, and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies. Additionally, NMCO was active in reducing leverage levels during the reporting period. Please see the Notes to Financial Statements for additional details.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NMCO significantly underperformed the S&P Municipal Yield Index. For purposes of this Performance Commentary, references to relative performance are in comparison to the S&P Municipal Yield Index.
The primary driver of NMCO’s underperformance was the Fund’s use of leverage, which detracted significantly. The Fund uses leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Further, the Fund’s exposure to Puerto Rico Electric Power Authority (PREPA) bonds detracted. PREPA underperformed given the ongoing restructuring, along with certain underperforming project finance bonds that faced project-specific challenges during the period. The Fund continued to hold PREPA based on the portfolio management team’s outlook.
Partially offsetting the Fund’s underperformance was its credit quality positioning, as credit spreads narrowed occasionally throughout the period. The Fund benefited from its overweights to below investment grade and
non-rated
bonds. Additional contributors included overweights to sectors such as transportation and dedicated tax, which were some of the
top-performing
sectors.
Nuveen Dynamic Municipal Opportunities Fund (NDMO)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NDMO’s investment objective is to provide total return through income exempt from regular federal income taxes and capital appreciation. NDMO invests primarily in municipal securities, the income on which is exempt from regular U.S. federal income tax and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by

executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies.
Additionally, during the reporting period NDMO was active in reducing leverage levels. Please see the Notes to Financial Statements for additional details. NDMO also actively sought to reduce its overall duration profile by selling positions in longer-duration bonds and by collapsing certain tender option bond (TOB) structures that were no longer cost-efficient because of rising borrowing costs.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NDMO underperformed the S&P Municipal Bond Index. For purposes of this Performance Commentary, references to relative performance are in comparison to the S&P Municipal Bond Index.
The primary detractor from NDMO’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Further, the Fund’s exposure to Puerto Rico Electric Power Authority (PREPA) bonds detracted. PREPA underperformed given the ongoing restructuring, along with certain underperforming project finance bonds that faced project-specific challenges during the period. The Fund continued to hold PREPA based on the portfolio management team’s outlook.
Partially offsetting the Fund’s underperformance were its overweights to the tobacco, transportation and dedicated tax sectors, which performed well, and an underweight to housing, which underperformed. In addition, NDMO was aided by strong performance from positions in Brightline, Puerto Rico sales tax revenue bonds known as COFINAs, Big River Steel and American Dream, and an opportunistic investment in short-term Treasury bills. The Fund continued to maintain exposures to the credits listed above but closed out its position in Treasury bills prior to the end of the reporting period.
The Fund managed the duration of its portfolio by shorting interest rate futures contracts. The interest rate futures contracts had a negligible impact on relative performance during the reporting period.

Fund Leverage
IMPACT OF THE FUNDS’ LEVERAGE STRATEGY ON PERFORMANCE
One important factor impacting the returns of the Funds’ common shares relative to their comparative benchmarks was the Funds’ use of leverage through their issuance of preferred shares and/or investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. The Funds use leverage because our research has shown that, over time, leveraging provides opportunities for additional income. The opportunity arises when short-term rates that a Fund pays on its leveraging instruments are lower than the interest the Fund earns on its portfolio of long-term bonds that it has bought with the proceeds of that leverage.
However, use of leverage can expose Fund common shares to additional price volatility. When a Fund uses leverage, the Fund’s common shares will experience a greater increase in their net asset value if the securities acquired through the use of leverage increase in value, but will also experience a correspondingly larger decline in their net asset value if the securities acquired through leverage decline in value. All this will make the shares’ total return performance more variable over time.
In addition, common share income in levered funds will typically decrease in comparison to unlevered funds when short-term interest rates increase and increase when short-term interest rates decrease. In recent quarters, fund leverage expenses have generally tracked the overall movement of short-term interest rates. While fund leverage expenses are higher than their prior year lows, leverage nevertheless continues to provide the opportunity for incremental common share income, particularly over longer-term periods.
NVG, NZF, NMZ and NDMO’s use of leverage detracted from relative performance over this reporting period while NMCO’s use of leverage significantly detracted. However, NMZ’s use of leverage was accretive to overall common share income.
As of October 31, 2023, the Funds’ percentages of leverage are as shown in the accompanying table.

|  | NVG |  |  | NZF |  |  | NMZ |  |  | NMCO* |  |  | NDMO |
Effective Leverage ** |  |  | 43.94% |  |  |  | 42.40% |  |  |  | 42.51% |  |  |  | 44.94% |  |  |  | 29.20% |
Regulatory Leverage ** |  |  | 41.07% |  |  |  | 36.26% |  |  |  | 25.41% |  |  |  | 43.82% |  |  |  | 29.14% |

* | Percentages do not include preferred shares noticed for redemption as noted on Statement of Assets and Liabilities.

** | Effective Leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative and other investments in a Fund’s portfolio that increase the Fund’s investment exposure. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage. Regulatory leverage consists of preferred shares issued or borrowings of a Fund. Both of these are part of a Fund’s capital structure. A Fund, however, may from time to time borrow on a typically transient basis in connection with its day-to-day operations, primarily in connection with the need to settle portfolio trades. Such incidental borrowings are excluded from the calculation of a Fund’s effective leverage ratio. Regulatory leverage is subject to asset coverage limits set forth in the Investment Company Act of 1940.

Common Share Information
NVG, NZF, NMZ and NMCO COMMON SHARE DISTRIBUTION INFORMATION
The following information regarding the distributions for NVG, NZF, NMZ and NMCO are current as of October 31, 2023. Each Fund’s distribution levels may vary over time based on each Fund’s investment activity and portfolio investments value changes.
During the current reporting period, each Fund’s distributions to common shareholders were as shown in the accompanying table.

|  | Per Common Share Amounts |
Monthly Distributions (Ex-Dividend Date) |  | NVG |  |  | NZF |  |  | NMZ |  |  | NMCO |
November |  |  | $0.0545 |  |  |  | $0.0505 |  |  |  | $0.0535 |  |  |  | $0.0575 |

Total Distributions from Net Investment Income |  |  | $0.5340 |  |  |  | $0.5312 |  |  |  | $0.5590 |  |  |  | $0.6180 |
Yields |  | NVG |  |  | NZF |  |  | NMZ |  |  | NMCO |
Market Yield 1 |  |  | 5.08% |  |  |  | 5.11% |  |  |  | 6.09% |  |  |  | 6.30% |
Taxable-Equivalent Yield 1 |  |  | 8.58% |  |  |  | 8.63% |  |  |  | 10.14% |  |  |  | 10.56% |

1 | Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is based on a federal income tax rate of 40.8%. Your actual federal income tax rate may differ from the assumed rate. The Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on payments made during the previous calendar year) that was not exempt from federal income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.

NVG, NZF, NMZ and NMCO seek to pay regular monthly dividends out of their net investment income at a rate that reflects their past and projected net income performance. To permit each Fund to maintain a more stable monthly dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net income actually earned by the Fund during the period. Distributions to common shareholders are determined on a tax basis, which may differ from amounts recorded in the accounting records. In instances where the monthly dividend exceeds the earned net investment income, the Fund would report a negative undistributed net ordinary income. Refer to Notes to Financial Statements 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 NVG and NZF 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. During the current fiscal period, NMZ’s and NMCO’s distributions were slightly greater than each Fund’s interest income, net of Fund expenses. As a result a portion of NMZ’s and NMCO’s distributions were deemed to be a return of capital. For financial reporting purposes, the per share amounts of each Fund’s distributions for the reporting period are presented in this report’s Financial Highlights. For income tax purposes, distribution information for each Fund as of its most recent tax year end is presented within the Notes to Financial Statements of this report.
Updated Distribution Policy for NVG, NZF, NMZ and NMCO
On October 23, 2023, the Funds’ Board of Trustees (the “Board”) updated each Fund’s distribution policy. Effective for distributions payable on December 1, 2023, each Fund’s distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to shareholders of its best estimate of the distribution sources at that the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’
1099-DIV
forms after the end of the year.

Common Share Information
(continued)
COMMON SHARE DISTRIBUTION INFORMATION FOR NDMO
NDMO makes regular cash distributions to shareholders of a stated dollar amount per share. Subject to approval and oversight by the Board of Trustees, the Fund seeks to maintain a stable distribution level designed to deliver the long-term return potential of the Fund’s investment strategy through regular distributions (a “Managed Distribution Program”). The practice of maintaining a stable distribution level had no material effect on the Fund’s investment strategy during the most recent fiscal period and is not expected to have such an effect in future periods, however, distributions in excess of Fund returns will cause its NAV per share to erode. For additional information, refer to the distribution information section below and in the Notes to Financial Statements herein.
This notice provides shareholders with information regarding fund distributions, as required by current securities laws. You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the terms of the Fund’s Managed Distribution Policy.
The following table provides estimates of the Fund’s distribution sources, reflecting
year-to-date
cumulative experience through the
month-end
prior to the latest distribution. The Fund attributes these estimates equally to each regular distribution throughout the year. Consequently, the estimated information as of the specified
month-end
shown below is for the current distribution, and also represents an updated estimate for all prior months in the year. It is estimated that the Fund has distributed more than its income and net realized capital gains; therefore, a portion of the distributions may be (and is shown below as being estimated to be) a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.”
The amounts and sources of distributions reported in this notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send a Form
1099-DIV
for the calendar year that will tell you how to report these distributions for federal income tax purposes. More details about the Fund’s distributions and the basis for these estimates are available on www.nuveen.com/cef.

Report of Independent Registered
Public Accounting Firm
To the Board of Trustees and Shareholders of Nuveen
AMT-Free
Municipal Credit Income Fund, Nuveen Municipal Credit Income Fund, Nuveen Municipal High Income Opportunity Fund, Nuveen Municipal Credit Opportunities Fund, and Nuveen Dynamic Municipal Opportunities Fund
Opinion on the Financial Statements
We have audited the accompanying statements of assets and liabilities of the Funds Listed in Appendix A (the Funds), including the portfolios of investments, as of October 31, 2023, the related statements of operations, cash flows and changes in net assets for the Funds and periods listed in Appendix A, and the related notes (collectively, the financial statements) and the financial highlights for the Funds and periods listed in Appendix A. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of October 31, 2023, the results of their operations, cash flows and the changes in their net assets for the periods listed in Appendix A, and the financial highlights for the Funds and periods listed in Appendix A, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of October 31, 2023, by correspondence with custodians and brokers; when replies were not received from brokers, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp.

In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.

The rate disclosed, as well as the reference rate and spread, where applicable, is that in effect as of the end of the reporting period. This rate changes periodically based on market conditions or a specified market index.

(m) | VRDP Shares, Net as a percentage of Total Investments is 28.0%.

144A | Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

(a) | All percentages shown in the Portfolio of Investments are based on net assets applicable to common shares unless otherwise noted.

(b) | Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.

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

(d) | Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.

(e) | Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.

(f) | For fair value measurement disclosure purposes, investment classified as Level 3.

(g) | Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.

(i) | Energy Harbor Corp (ENGH) common stock received as part of the bankruptcy settlements during February 2020 for Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2006B, 3.500%, 12/01/35, Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Nuclear Generation Project, Refunding Series 2008C, 3.950%, 11/01/32, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2008C, 3.950%, 11/01/32. Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp. (“Vistra”) announced that it has executed a definitive agreement with Energy Harbor Corp., pursuant to which Energy Harbor will merge with and into a newly-formed subsidiary of Vistra. In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.

(j) | Non-income producing; issuer has not declared an ex-dividend date within the past twelve months.

(k) | MFP Shares, Net as a percentage of Total Investments is 16.1%.

(l) | VRDP Shares, Net as a percentage of Total Investments is 17.0%.

144A | Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

AMT | Alternative Minimum Tax

ETM | Escrowed to maturity

IF | Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.

LIBOR | London Inter-Bank Offered Rate

PIK | Payment-in-kind (“PIK”) security. Depending on the terms of the security, income may be received in the form of cash, securities, or a combination of both. The PIK rate shown, where applicable, represents the annualized rate of the last PIK payment made by the issuer as of the end of the reporting period.

UB | Underlying bond of an inverse floating rate trust reflected as a financing transaction.

WI/DD | When-issued or delayed delivery security.

(b) | Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.

(c) | Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.

(d) | Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.

(e) | For fair value measurement disclosure purposes, investment classified as Level 3.

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

(g) | Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.

(h) | Principal Amount (000) rounds to less than $1,000.

(i) | Energy Harbor Corp (ENGH) common stock received as part of the bankruptcy settlements during February 2020 for Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2006A, 3.500%, 4/01/41, Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2006B, 3.500%, 12/01/35, Ohio Air Quality Development Authority, Ohio, Air Quality Development Revenue Bonds, FirstEnergy Generation Corporation Project, Series 2009A, 5.700%, 8/01/20, Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Generation Corporation Project, Refunding Series 2009B, 3.100%, 3/01/23, Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Nuclear Generation Project, Refunding Series 2008C, 3.950%, 11/01/32, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2005B, 4.000%, 1/01/34, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2006A, 3.000%, 5/15/20, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2008B, 3.625%, 10/01/33, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2008C, 3.950%, 11/01/32, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2010A, 3.750%, 7/01/33, Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, Shippingport Project, First Energy Guarantor, Series 2006A, 2.550%, 11/01/41. Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp. (“Vistra”) announced that it has executed a definitive agreement with Energy Harbor Corp., pursuant to which Energy Harbor will merge with and into a newly-formed subsidiary of Vistra. In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.

(j) | Non-income producing; issuer has not declared an ex-dividend date within the past twelve months.

(k) | Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.

(l) | Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.

(m) | Senior loan received as part of the bondholder funding agreement during June 2023 for Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, KDC Agribusiness Fairless Hills LLC Project, Series 2020A-1, 10.000%, 12/01/40, 144A, Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, KDC Agribusiness Fairless Hills LLC Project, Series 2020A-2, 10.000%, 12/01/40, (AMT), 144A, Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, KDC Agribusiness Fairless Hills LLC Project, Series 2021A, 10.000%, 12/01/31.

|  | Portfolio of Investments October 31, 2023

(i) | Energy Harbor Corp (ENGH) common stock received as part of the bankruptcy settlements during February 2020 for Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Bonds, FirstEnergy Nuclear Generation Project, Refunding Series 2005A, 4.000%, 1/01/35, Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2006A, 3.500%, 4/01/41, Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2006B, 3.500%, 12/01/35, Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2008A, 2.700%, 4/01/35, Ohio Air Quality Development Authority, Ohio, Air Quality Development Revenue Bonds, FirstEnergy Generation Corporation Project, Series 2009A, 5.700%, 8/01/20, Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Generation Corporation Project, Refunding Series 2009B, 3.100%, 3/01/23, Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Generation Project, Refunding Series 2006A, 3.750%, 12/01/23, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2006A, 3.000%, 5/15/20, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2006B, 4.000%, 12/01/33, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2010C, 4.000%, 6/01/33. Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp. (“Vistra”) announced that it has executed a definitive agreement with Energy Harbor Corp., pursuant to which Energy Harbor will merge with and into a newly-formed subsidiary of Vistra. In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.

(j) | Non-income producing; issuer has not declared an ex-dividend date within the past twelve months.

(k) | In May 2023, Talen Energy completed a Chapter 11 plan of reorganization whereby the Fund received Talen Energy Common Stock in exchange for the following portfolio holding: Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Refunding Bonds, PPL Energy Supply, LLC Project, Series 2009A, 6.400%, 12/01/38.

(l) | Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.

(m) | Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.

(n) | Senior loan received as part of the bondholder funding agreement during June 2023 for Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, KDC Agribusiness Fairless Hills LLC Project, Series 2020A-1, 10.000%, 12/01/40, 144A, Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, KDC Agribusiness Fairless Hills LLC Project, Series 2020A-2, 10.000%, 12/01/40, (AMT), 144A, Pennsylvania Economic Development Financing Authority, Exempt Facilities Revenue Bonds, KDC Agribusiness Fairless Hills LLC Project, Series 2021A, 10.000%, 12/01/31.

(o) | MFP Shares, Net as a percentage of Total Investments is 42.9%.

144A | Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

AMT | Alternative Minimum Tax

N/A | Not Applicable.

PIK | Payment-in-kind (“PIK”) security. Depending on the terms of the security, income may be received in the form of cash, securities, or a combination of both. The PIK rate shown, where applicable, represents the annualized rate of the last PIK payment made by the issuer as of the end of the reporting period.

UB | Underlying bond of an inverse floating rate trust reflected as a financing transaction.

WI/DD | When-issued or delayed delivery security.

Notes to Financial Statements

1. | General Information

Fund Information:
The funds covered in this report and their corresponding New York Stock Exchange (“NYSE”) symbols are as follows (each a “Fund” and collectively, the “Funds”):

| · |  | Nuveen AMT-Free Municipal Credit Income Fund (NVG)

| · |  | Nuveen Municipal Credit Income Fund (NZF)

| · |  | Nuveen Municipal High Income Opportunity Fund (NMZ)

| · |  | Nuveen Municipal Credit Opportunities Fund (NMCO)

| · |  | Nuveen Dynamic Municipal Opportunities Fund (NDMO)

The Funds are registered under the Investment Company Act of 1940 (the “1940 Act”), as amended, as diversified
closed-end
management investment companies. NVG, NZF, NMZ, NMCO and NDMO were organized as Massachusetts business trusts on July 12, 1999, March 21, 2001, October 8, 2003, April 18, 2019 and November 4, 2019, respectively.
Current Fiscal Period:
The end of the reporting period for the Funds is October 31, 2023, and the period covered by these Notes to Financial Statements is the fiscal year ended October 31, 2023 (the “current fiscal period”).
Investment Adviser and
Sub-Adviser:
The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolio, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered
into sub-advisory
agreements with Nuveen Asset Management, LLC, (the
“Sub-Adviser”),
a subsidiary of the Adviser, under which the
Sub-Adviser
manages the investment portfolios of the Funds.
Fund Reorganization and Mergers:
Effective prior to the opening of business on June 6, 2022, Nuveen Enhanced Municipal Value Fund (NEV) (the “Target Fund”) was reorganized into Nuveen Municipal Credit Income Fund (“NZF” or the “Acquiring Fund”), (the “Reorganization”). Upon the closing of the Reorganization, the Target Fund transferred its assets to the Acquiring Fund in exchange for common shares of the Acquiring Fund and the assumption by the Acquiring Fund of the liabilities of the Target Fund. The Target Fund was then dissolved and terminated in accordance with its Declaration of Trust. Shareholders of the Target Fund became shareholders of the Acquiring Fund. Holders of common shares of the Target Fund received newly issued common shares of the Acquiring Fund, the aggregate net asset value (“NAV”) of which was equal to the aggregate NAV of the common shares of the Target Fund held immediately prior to the Reorganization (including for this purpose fractional Acquiring Fund shares to which shareholders were entitled). For accounting and performance reporting purposes, the Acquiring Fund was the survivor of the reorganization.
Effective prior to the opening of business on April 17, 2023, Nuveen Ohio Quality Municipal Income Fund (NUO) and Nuveen Georgia Quality Municipal Income Fund (NKG) (the “Target Funds”) were each merged into NZF (the “Acquiring Fund”) (each a “Merger”).
With respect to each Merger of a Target Fund with and into the Acquiring Fund, the separate legal existence of the Target Fund ceased for all purposes and the Acquiring Fund succeeded to all the assets and assumed all the liabilities of the Target Fund. Shares of the Target Fund were converted into newly issued shares of the Acquiring Fund. Holders of common shares of the Target Fund received newly issued common shares of the Acquiring Fund, the aggregate net asset value (“NAV”) of which was equal to the aggregate NAV of the common shares of the Target Fund held immediately prior to the Merger (including for this purpose fractional Acquiring Fund shares to which shareholders were entitled). For accounting and performance reporting purposes, the Acquiring Fund is the survivor. Refer to Note 11 for further details on each Merger.
Developments Regarding the Fund’s Control Share
By-Law:
On October 5, 2020, the Fund and certain other
closed-end
funds in the Nuveen fund complex amended their
by-laws.
Among other things, the amended
by-laws
included provisions pursuant to which, in summary, a shareholder who obtains beneficial ownership of common shares in a Control Share Acquisition (as defined in the
by-laws)
shall have the same voting rights as other common shareholders only to the extent authorized by the other disinterested shareholders (the “Control Share
By-Law”).
On January 14, 2021, a shareholder of certain Nuveen
closed-end
funds filed a civil complaint in the U.S. District Court for the Southern District of New York (the “District Court”) against certain Nuveen funds and their trustees, seeking a declaration that such funds’ Control Share
By-Laws
violate the 1940 Act, rescission of such fund’s Control Share
By-Laws
and a permanent injunction against such funds applying the Control Share
By-Laws.
On February 18, 2022, the District Court granted judgment in favor of the plaintiff’s claim for rescission of such funds’ Control Share
By-Laws
and the plaintiff’s declaratory judgment claim, and declared that such funds’ Control Share
By-Laws
violate Section 18(i) of the 1940 Act. Following review of the judgment of the District Court, on February 22, 2022, the Board of Trustees (the “Board”) amended the Fund’s
by-laws
to provide that the Fund’s Control Share
By-Law
shall be of no force and effect for so long as the judgment of the District Court is effective and that if the judgment of the District Court is reversed, overturned, vacated, stayed, or otherwise nullified, the Fund’s Control Share
By-Law
will be automatically reinstated and apply to any beneficial owner of common shares acquired in a Control Share Acquisition, regardless of whether such Control Share Acquisition occurs before or after such reinstatement, for the duration of the stay or upon issuance of the mandate reversing, overturning, vacating or otherwise nullifying the judgment of the District Court. On February 25, 2022, the Board and the Funds appealed the District Court’s decision to the U.S. Court of Appeals for the Second Circuit. On November 30, 2023, the U.S. Court of Appeals for the Second Circuit upheld the opinion of the District Court.

2. | Significant Accounting Policies

The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. Each Fund is an investment company and follows accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services — Investment Companies. The NAV for financial reporting purposes may differ from the NAV for processing security and shareholder 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 Funds.
Compensation:
The Funds pay no compensation directly to those of its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Board has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.
Custodian Fee Credit:
As an alternative to overnight investments, each Fund has an arrangement with its custodian bank, State Street Bank and Trust Company, (the “Custodian”) whereby certain custodian fees and expenses are reduced by net credits earned on each Fund’s cash on deposit with the bank. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the Custodian. The amount of custodian fee credit earned by a Fund is recognized on the Statement of Operations as a component of “Custodian expenses, net.” During the current reporting period, the custodian fee credit earned by each Fund was as follows:

Fund |  | Gross Custodian Fee Credits |
NVG |  | $ | 253,070 |
NZF |  |  | 176,540 |
NMZ |  |  | 70,972 |
NMCO |  |  | 28,638 |
NDMO |  |  | 73,421 |

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.
NDMO makes monthly cash distributions to common shareholders of a stated dollar amount per share. Subject to approval and oversight by the Board, the Fund seeks to maintain a stable distribution level designed to deliver the long-term return potential of the Fund’s investment strategy through regular monthly distributions (a “Managed Distribution Program”). Total distributions during a calendar year generally will be made from the Fund’s net investment income, net realized capital gains and net unrealized capital gains in the Fund’s portfolio, if any. The portion of distributions paid attributed to net unrealized gains, if any, is distributed from the Fund’s assets and is treated by common shareholders as a nontaxable distribution (“return of capital”) for tax purposes. In the event that total distributions during a calendar year exceed the Fund’s total return on NAV, the difference will reduce NAV per share. If the Fund’s total return on NAV exceeds total distributions during a calendar year, the excess will be reflected as an increase in NAV per share. The final determination of the source and character of all distributions paid by the Fund during the fiscal year is made after the end of the fiscal year and is reflected in the financial statements contained in the annual report as of October 31 each year.
Indemnifications:
Under the Funds’ organizational documents, their officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
Investments and Investment Income:
Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Investment income is comprised of interest income, which 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 Funds may enter into transactions subject to enforceable International Swaps and Derivatives Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each 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, each Fund manages its cash collateral and securities collateral on a counterparty basis. With respect to certain counterparties, in accordance with the terms of the netting agreements, collateral posted to the Funds is held in a segregated account by the Funds’ custodian and/or with respect to those amounts which can be sold or repledged, are presented in the Funds’ Portfolio of Investments or Statement of Assets and Liabilities.

Notes to Financial Statements
(continued)
The Funds’ investments subject to netting agreements as of the end of the reporting period, if any, are further described later in these Notes to Financials.
New Accounting Pronouncement:
In March 2020, FASB issued Accounting Standards Update (“ASU”)
2020-04,
Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The main objective of the new guidance is to provide relief to companies that will be impacted by the expected change in benchmark interest rates, 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 Funds may elect to apply the amendments as of March 12, 2020 through December 31, 2022. In December 2022, FASB deferred ASU
2022-04
and issued ASU
2022-06,
Reference Rate Reform: Deferral of the Sunset Date of Topic 848, which extends the application of the amendments through December 31, 2024. Management has not yet elected to apply the amendments, is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Funds’ investments and has currently determined that it is unlikely the ASU’s adoption will have a significant impact on the Funds’ financial statements and various filings.

3. | Investment Valuation and Fair Value Measurements

The Funds’ investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Adviser, subject to oversight of 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 Funds’ major classifications of assets and liabilities measured at fair value follows:
Equity securities and exchange-traded funds listed or traded on a national market or exchange are valued based on their last reported sales price or official closing price of such market or exchange on the valuation date. Foreign equity securities and registered investment companies that trade on a foreign exchange are valued at the last reported sales price or official closing price on the principal exchange where traded, and converted to U.S. dollars at the prevailing rates of exchange on the valuation date. For events affecting the value of foreign securities between the time when the exchange on which they are traded closes and the time when the Funds’ net assets are calculated, such securities will be valued at fair value in accordance with procedures adopted by the Adviser, subject to the oversight of the Board. To the extent these securities are actively traded and no valuation adjustments are applied, they are generally classified as Level 1. When valuation adjustments are applied to the most recent last sales price or official closing price, these securities are generally classified as Level 2.
Prices of fixed-income securities are generally provided by pricing services approved by the Adviser, which is subject to review by the Adviser and oversight of the Board. Pricing services establish 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, pricing services may consider information about a security, its issuer or market activity provided by the Adviser. These securities are generally classified as Level 2.
Investments in investment companies are valued at their respective NAVs or share price on the valuation date and are generally classified as Level 1.
For any portfolio security or derivative for which market quotations are not readily available or for which the Adviser deems the valuations derived using the valuation procedures described above not to reflect fair value, the Adviser will determine a fair value in good faith using alternative procedures approved by the Adviser, subject to the oversight of the Board. As a general principle, the fair value of a security is 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; otherwise they would be classified as Level 3.
The following table summarizes the market value of the Funds’ investments as of the end of the reporting period, based on the inputs used to value them:

The table below presents the transfers in and out of the three valuation levels for the Funds as of the end of the reporting period when compared to the valuation levels at the end of the previous fiscal year. Changes in valuation inputs or methodologies may result in transfers into or out of an assigned level within the fair value hierarchy. Transfers in or out of levels are generally due to the availability of publicly available information and to the significance or extent the Adviser determines that the valuation inputs or methodologies may impact the valuation of those securities.

4. | Portfolio Securities

Inverse Floating Rate Securities:
Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond (referred to as an “Underlying Bond”), typically with a fixed interest rate, into a special purpose tender option bond (“TOB”) trust (referred to as the “TOB Trust”) created by or at the direction of one or more Funds. In turn, the TOB Trust issues (a) floating rate certificates (referred to as “Floaters”), in face amounts equal to some fraction of the Underlying Bond’s par amount or market value, and (b) an inverse floating rate certificate (referred to as an “Inverse Floater”) that represents all remaining or residual interest in the TOB Trust. Floaters typically pay short-term
tax-exempt
interest rates to third parties who are also provided a right to tender their certificate and receive its par value, which may be paid from the proceeds of a remarketing of the Floaters, by a loan to the TOB Trust from a third party liquidity provider (“Liquidity Provider”), or by the sale of assets from the TOB Trust. The Inverse Floater is issued to a long term investor, such as one or more Funds. The income received by the Inverse Floater holder varies inversely with the short-term rate paid to holders of the Floaters, and in most circumstances the Inverse Floater holder bears substantially all of the Underlying Bond’s downside investment risk and also benefits disproportionately from any potential appreciation of the Underlying Bond’s value. The value of an Inverse Floater will be more volatile than that of the Underlying Bond because the interest rate is dependent on not only the fixed coupon rate of the Underlying Bond but also on the short-term interest paid on the Floaters, and because the Inverse Floater essentially bears the risk of loss (and possible gain) of the greater face value of the Underlying Bond.
The Inverse Floater held by a Fund gives the Fund the right to (a) cause the holders of the Floaters to tender their certificates at par (or slightly more than par in certain circumstances), and (b) have the trustee of the TOB Trust (the “Trustee”) transfer the Underlying Bond held by the TOB Trust to the Fund, thereby collapsing the TOB Trust.
The Fund may acquire an Inverse Floater in a transaction where it (a) transfers an Underlying Bond that it owns to a TOB Trust created by a third party or (b) transfers an Underlying Bond that it owns, or that it has purchased in a secondary market transaction for the purpose of creating an Inverse Floater, to a TOB Trust created at its direction, and in return receives the Inverse Floater of the TOB Trust (referred to as a “self-deposited Inverse Floater”). A Fund may also purchase an Inverse Floater in a secondary market transaction from a third party creator of the TOB Trust without first owning the Underlying Bond (referred to as an “externally-deposited Inverse Floater”).
An investment in a self-deposited Inverse Floater is accounted for as a “financing” transaction (i.e., a secured borrowing). For a self-deposited Inverse Floater, the Underlying Bond deposited into the TOB Trust is identified in the Fund’s Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund recognizing as liabilities, labeled “Floating rate obligations” on the Statement of Assets and Liabilities, (a) the liquidation value of Floaters issued by the TOB Trust, and (b) the amount of any borrowings by the TOB Trust from a Liquidity Provider to enable the TOB Trust to purchase outstanding Floaters in lieu of a remarketing. In addition, the Fund recognizes in “Investment Income” the entire earnings of the Underlying Bond, and recognizes (a) the interest paid to the holders of the Floaters or on the TOB Trust’s borrowings, and (b) other expenses related to remarketing, administration, trustee, liquidity and other services to a TOB Trust, as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. Earnings due from the Underlying Bond and interest due to the holders of the Floaters as of the end of the reporting period are recognized as components of “Receivable for interest” and “Payable for interest” on the Statement of Assets and Liabilities, respectively.
In contrast, an investment in an externally-deposited Inverse Floater is accounted for as a purchase of the Inverse Floater and is identified in the Fund’s Portfolio of Investments as “(IF) – Inverse floating rate investment.” For an externally-deposited Inverse Floater, a Fund’s Statement of Assets and Liabilities recognizes the Inverse Floater and not the Underlying Bond as an asset, and the Fund does not recognize the Floaters, or any related borrowings from a Liquidity Provider, as a liability. Additionally, the Fund reflects in “Investment Income” only the net amount of earnings on the Inverse Floater (net of the interest paid to the holders of the Floaters or the Liquidity Provider as lender, and the expenses of the Trust), and does not show the amount of that interest paid or the expenses of the TOB Trust as described above as interest expense on the Statement of Operations.
Fees paid upon the creation of a TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters are recognized as part of the cost basis of the Inverse Floater and are capitalized over the term of the TOB Trust.
As of the end of the reporting period, the aggregate value of Floaters issued by each Fund’s TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters was as follows:

Fund |  | Floating Rate Obligations: Self- Deposited Inverse Floaters |  |  | Floating Rate Obligations: Externally-Deposited Inverse Floaters |  |  | Total |
NVG |  | $ | 210,540,000 |  |  | $ | 8,160,000 |  |  | $ | 218,700,000 |
NZF |  |  | 374,706,000 |  |  |  | 12,755,000 |  |  |  | 387,461,000 |
NMZ |  |  | 406,701,000 |  |  |  | 11,290,000 |  |  |  | 417,991,000 |
NMCO |  |  | 19,960,000 |  |  |  | – |  |  |  | 19,960,000 |
NDMO |  |  | 650,000 |  |  |  | – |  |  |  | 650,000 |

During the current fiscal period, the average amount of Floaters (including any borrowings from a Liquidity Provider) outstanding, and the average annual interest rates and fees related to self-deposited Inverse Floaters, were as follows:
222

Fund |  | Average Floating Rate Obligations Outstanding |  |  | Average Annual Interest Rate And Fees
NVG |  | $ | 205,665,849 |  |  | 3.68%
NZF |  |  | 280,044,101 |  |  | 3.86
NMZ |  |  | 427,319,148 |  |  | 3.74
NMCO |  |  | 23,035,685 |  |  | 3.79
NDMO |  |  | 3,293,726 |  |  | 3.50

TOB Trusts are supported by a liquidity facility provided by a Liquidity Provider pursuant to which the Liquidity Provider agrees, in the event that Floaters are (a) tendered to the Trustee for remarketing and the remarketing does not occur, or (b) subject to mandatory tender pursuant to the terms of the TOB Trust agreement, to either purchase Floaters or to provide the Trustee with an advance from a loan facility to fund the purchase of Floaters by the TOB Trust. In certain circumstances, the Liquidity Provider may otherwise elect to have the Trustee sell the Underlying Bond to retire the Floaters that were tendered and not remarketed prior to providing such a loan. In these circumstances, the Liquidity Provider remains obligated to provide a loan to the extent that the proceeds of the sale of the Underlying Bond are not sufficient to pay the purchase price of the Floaters.
The size of the commitment under the loan facility for a given TOB Trust is at least equal to the balance of that TOB Trust’s outstanding Floaters plus any accrued interest. In consideration of the loan facility, fee schedules are in place and are charged by the Liquidity Provider(s). Any loans made by the Liquidity Provider will be secured by the purchased Floaters held by the TOB Trust. Interest paid on any outstanding loan balances will be effectively borne by the Fund that owns the Inverse Floaters of the TOB Trust that has incurred the borrowing and may be at a rate that is greater than the rate that would have been paid had the Floaters been successfully remarketed.
As described above, any amounts outstanding under a liquidity facility are recognized as a component of “Floating rate obligations” on the Statement of Assets and Liabilities by the Fund holding the corresponding Inverse Floaters issued by the borrowing TOB Trust. As of the end of the reporting period, there were no loans outstanding under any such facility.
Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a “recourse arrangement”) (TOB Trusts involving such agreements are referred to herein as “Recourse Trusts”), under which a Fund agrees to reimburse the Liquidity Provider for the Trust’s Floaters, in certain circumstances, for the amount (if any) by which the liquidation value of the Underlying Bond held by the TOB Trust may fall short of the sum of the liquidation value of the Floaters issued by the TOB Trust plus any amounts borrowed by the TOB Trust from the Liquidity Provider, plus any shortfalls in interest cash flows (sometimes referred to as “shortfall payments”). Under these agreements, a Fund’s potential exposure to losses related to or on an Inverse Floater may increase beyond the value of the Inverse Floater as a Fund may potentially be liable to fulfill all amounts owed to holders of the Floaters or the Liquidity Provider. Any such shortfall amount in the aggregate is recognized as “Unrealized depreciation on Recourse Trusts” on the Statement of Assets and Liabilities. During the current fiscal period NZF, NMZ and NMCO made Shortfall Payments in the amounts of $3,272,586, $874,057 and $178,372, respectively. Such amounts are recognized as a component of “Net realized gain (loss) from investments” on the Statement of Operations. NVG and NDMO did not make shortfall Payments during the current reporting period.
As of the end of the reporting period, the Funds maximum exposure to the Floaters issued by Recourse Trusts for self-deposited Inverse Floaters and externally-deposited Inverse Floaters was as follows:

Fund |  | Maximum Exposure to Recourse Trusts: Self-Deposited Inverse Floaters |  |  | Maximum Exposure to Recourse Trusts: Externally-Deposited Inverse Floaters |  |  | Total |
NVG |  | $ | 208,240,000 |  |  | $ | – |  |  | $ | 208,240,000 |
NZF |  |  | 368,406,000 |  |  |  | 12,755,000 |  |  |  | 381,161,000 |
NMZ |  |  | 406,701,000 |  |  |  | 11,290,000 |  |  |  | 417,991,000 |
NMCO |  |  | 19,960,000 |  |  |  | – |  |  |  | 19,960,000 |
NDMO |  |  | 650,000 |  |  |  | – |  |  |  | 650,000 |

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.
Purchases and Sales:
Long-term purchases and sales during the current fiscal period were as follows:

Fund |  | Non-U.S. Government Purchases |  |  | Non-U.S. Government Sales and Maturities |
NVG |  | $ | 792,547,111 |  |  | $ | 933,653,774 |
NZF |  |  | 1,181,054,995 |  |  |  | 1,026,257,806 |
NMZ |  |  | 544,946,481 |  |  |  | 583,454,738 |

NDMO |  |  | 724,765,592 |  |  |  | 684,528,955 |

The Funds may purchase securities on a when-issued or delayed-delivery basis. Securities purchased on a when-issued or delayed-delivery basis may have extended settlement periods; interest income is not accrued until settlement date. Any securities so purchased are subject to market fluctuation during this period. If a Fund has outstanding when-issued/delayed-delivery purchases commitments as of the end of the reporting period, such amounts are recognized on the Statement of Assets and Liabilities.

5. | Derivative Investments

Each Fund is authorized to invest in certain derivative instruments. As defined by U.S. GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variables. Investments in derivatives as of the end of and/or during the current fiscal period, if any, are included within the Statement of Assets and Liabilities and the Statement of Operations, respectively.
Futures Contracts:
During the current fiscal period, NDMO managed the duration of its portfolio by shorting interest rate futures contracts.
A futures contract is an agreement between two parties to buy and sell a financial instrument for a set price on a future date. Upon execution of a futures contract, the Fund is obligated to deposit cash or eligible securities, also known as “initial margin,” into an account at its clearing broker equal to a specified percentage of the contract amount. Securities deposited for initial margin, if any, are identified in the Portfolio of Investments and cash deposited for initial margin, if any, is reflected on the Statement of Assets and Liabilities.
During the period the futures contract is open, changes in the market value of the contract are recognized as an unrealized gain or loss by
“marking-to-market”
on a daily basis. The Fund and the clearing broker are obligated to settle monies on a daily basis representing the changes in the value of the contracts. These daily cash settlements are known as “variation margin” and is recognized on the Statement of Assets and Liabilities as a receivable or payable for variation margin on futures contracts. When the contract is closed or expired, the Fund records a realized gain or loss equal to the difference between the value of the contract on the closing date and value of the contract when originally entered into. The net realized gain or loss and the change in unrealized appreciation (depreciation) on futures contracts held during the period is included on the Statement of Operations.
Risks of investments in futures contracts include the possible adverse movement in the price of the securities or indices underlying the contracts, the possibility that there may not be a liquid secondary market for the contracts and/or that a change in the value of the contract may not correlate with a change in the value of the underlying securities or indices.
The average notional amount of futures contracts outstanding during the current fiscal period was as follows:

Fund |  | Average Notional Amount of Futures Contracts Outstanding * |
NDMO |  |  | $3,032,340 |

* | The average notional amount is calculated based on the absolute aggregate notional amount of contracts outstanding at the beginning of the current fiscal period and at the end of each fiscal quarter within the current fiscal period.

During the current fiscal period, the effect of derivative contracts on the Fund’s Statement of Operations was as follows:

Derivative Instrument |  | Risk Exposure |  |  |  | Net Realized Gain (Loss) |  |  | Change in Unrealized Appreciation (Depreciation) |
NDMO |  |  |  |  |  |  |  |  |  |  |  |
Futures contracts |  | Interest rate |  |  |  |  | $831,869 |  |  |  | $(2,140,765) |

Market and Counterparty Credit Risk:
In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.

Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a
pre-determined
threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a
pre-determined
threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the
pre-determined
threshold amount.

Common Shares Equity Shelf Programs and Offering Costs:
The following Funds have filed a registration statement with the Securities and Exchange Commission (“SEC”) authorizing each Fund to issue additional common shares through one or more equity shelf programs (“Shelf Offering”), which became effective with the SEC during prior fiscal periods.
Under this Shelf Offering, the Funds, subject to market conditions, may raise additional equity capital by issuing additional common shares from time to time in varying amounts and by different offering methods at a net price at or above each Fund’s NAV per common share. In the event the Fund’s Shelf Offering registration statement is no longer current, the Fund may not issue additional common shares until a post-effective amendment to the registration statement has been filed with the SEC.
Maximum aggregate offering, common shares sold and offering proceeds, net of offering costs under each Fund’s Shelf Offering during the Funds’ current and prior fiscal period were as follows:

Preferred Shares
Adjustable Rate MuniFund Term Preferred Shares:
NMZ has issued and has outstanding Adjustable Rate MuniFund Term Preferred (“AMTP”) Shares, with a $100,000 liquidation preference per share. AMTP Shares are issued via private placement and are not publicly available.
As of the end of the reporting period, NMZ had $356,521,633 AMTP Shares at liquidation preference, net of deferred offering costs. Further details of the Fund’s AMTP Shares outstanding as of the end of the reporting period, were as follows:

Fund |  | Series |  |  | Shares Outstanding |  |  | Liquidation Preference |
NMZ |  |  | 2028 |  |  |  | 870 |  |  |  | $87,000,000 |
|  |  | 2031 |  |  |  | 1,700 |  |  |  | $170,000,000 |
|  |  | 2032 |  |  |  | 1,000 |  |  |  | $100,000,000 |

The Fund is obligated to redeem its AMTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed by the Fund. AMTP Shares are subject to optional and mandatory redemption in certain circumstances. The AMTP Shares may be redeemed at the option of the Fund, subject to payment of premium for approximately six months following the date of issuance (“Premium Expiration Date”), and at the redemption price per share thereafter. The redemption price per share is equal to the sum of the liquidation preference per share plus any accumulated but unpaid dividends.
AMTP Shares are short-term or short/intermediate-term instruments that pay a variable dividend rate tied to a short-term index, plus an additional fixed “spread” amount which is initially established at the time of issuance and may be adjusted in the future based upon a mutual agreement between the majority owner and the Fund. From
time-to-time
the majority owner may propose to the Fund an adjustment to the dividend rate. Should the majority owner and the Fund fail to agree upon an adjusted dividend rate, and such proposed dividend rate adjustment is not withdrawn, the Fund will be required to redeem all outstanding shares upon the end of a notice period.
In addition, the Fund may be obligated to redeem a certain amount of the AMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The Term Redemption Date and Premium Expiration Date for the Fund’s AMTP Shares are as follows:

Fund |  | Notice Period |  | Series |  |  | Term Redemption Date |  |  | Premium Expiration Date |
NMZ |  | 360-day |  |  | 2028 |  |  |  | March 1, 2028* |  |  |  | August 31, 2018 |
|  | 360-day |  |  | 2031 |  |  |  | April 1, 2031* |  |  |  | April 17, 2023 |
|  | 360-day |  |  | 2032 |  |  |  | June 1, 2032* |  |  |  | June 8, 2023 |

* | Subject to early termination by either the Fund or the holder.

The average liquidation preference of AMTP Shares outstanding and annualized dividend rate for the Fund during the current fiscal period were as follows:

Fund |  | Average Liquidation Preference of AMTP Shares Outstanding |  |  | Annualized Dividend Rate |
NMZ |  | $ | 357,000,000 |  |  |  | 4.10% |

AMTP Shares are subject to restrictions on transfer, generally do not trade, and market quotations are generally not available. The fair value of AMTP Shares is expected to be approximately their liquidation preference so long as the fixed “spread” on the AMTP Shares remains roughly in line with the “spread” being demanded by investors on instruments having similar terms in the current market environment. In present market conditions, the Fund’s Adviser has determined that the fair value of AMTP Shares is approximately their liquidation preference, but their fair value could vary if market conditions change materially. For financial reporting purposes, the liquidation preference of AMTP Shares is a liability and is recognized as a component of “AMTP Shares, Net” on the Statement of Assets and Liabilities.
AMTP Share dividends are treated as interest payments for financial reporting purposes. Unpaid dividends on AMTP Shares are recognized as a component of “Payable for interest” on the Statement of Assets and Liabilities. Dividends accrued on AMTP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.
Costs incurred in connection with the Fund’s offering of AMTP Shares were recorded as deferred charges, which are amortized over the life of the shares and are recognized as components of “AMTP Shares, Net” on the Statement of Assets and Liabilities and “Interest expense and amortization of offering costs” on the Statement of Operations.
MuniFund Preferred Shares:
NVG, NZF, NMCO and NDMO have issued and have outstanding MuniFund Preferred (“MFP”) Shares, with a $100,000
($1,000 for NVG’s Series B and Series C) liquidation preference per share. These MFP Shares were issued via private placement and are not publicly available.
The Funds are obligated to redeem their MFP Shares by the date as specified in its offering documents (“Term Redemption Date”), unless earlier redeemed by the Funds. MFP Shares are initially issued in a
pre-specified
mode, however, MFP Shares can be subsequently designated as an alternative mode at a later date at the discretion of the Funds. The modes within MFP Shares detail the dividend mechanics and are described as follows. At a subsequent date, the Funds may establish additional mode structures with the MFP Share.
•
Variable Rate Remarketed Mode (“VRRM”) – Dividends for MFP Shares within this mode will be established by a remarketing agent; therefore, market value of the MFP Shares is expected to approximate its liquidation preference. Shareholders have the ability to request a best-efforts tender of its shares upon seven days notice. If the remarketing agent is unable to identify an alternative purchaser, the shares will be retained by the shareholder requesting tender and the subsequent dividend rate will increase to its
step-up
dividend rate. If after one consecutive year of unsuccessful remarketing attempts, the Fund will be required to designate an alternative mode or redeem the shares.
Each Fund will pay a remarketing fee on the aggregate principal amount of all MFP Shares while designated in VRRM. Payments made by the Fund to the remarketing agent are recognized as “Remarketing fees” on the Statement of Operations.
•
Variable Rate Mode (“VRM”) – Dividends for MFP Shares designated in this mode are based upon a short-term index plus an additional fixed “spread” amount established at the time of issuance or renewal / conversion of its mode. At the end of the period of the mode, the Fund will be required to either extend the term of the mode, designate an alternative mode or redeem the MFP Shares.
The fair value of MFP Shares while in VRM are expected to approximate their liquidation preference so long as the fixed “spread” on the shares remains roughly in line with the “spread” being demanded by investors on instruments having similar terms in the current market. In current market conditions, the Adviser has determined that the fair value of the shares are approximately their liquidation preference, but their fair value could vary if market conditions change materially.
•
Variable Rate Demand Mode (“VRDM”) – Dividends for MFP Shares designated in this mode will be established by a remarketing agent; therefore, the market value of the MFP Shares is expected to approximate its liquidation preference. While in this mode, shares will have an unconditional liquidity feature that enable its shareholders to require a liquidity provider, which the Fund has entered into a contractual agreement, to purchase shares in the event that the shares are not able to be successfully remarketed. In the event that shares within this mode are unable to be successfully remarketed and are purchased by the liquidity provider, the dividend rate will be the maximum rate which is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the shares. Each Fund is required to redeem any shares that are still owned by a liquidity provider after six months of continuous, unsuccessful remarketing.
The Fund will pay a liquidity and remarketing fee on the aggregate principal amount of all MFP shares while within VRDM. Payments made by the Fund to the liquidity provider and remarketing agent are recognized as “Liquidity fees” and “Remarketing fees”, respectively, on the Statement Operations.

* | Remarketing fees as a percentage of the aggregate principal amount of all VRDP Shares outstanding for each series.

** | Not applicable. Series is considered to be Special Rate VRDP and therefore does not pay a remarketing fee.

VRDP Shares include a liquidity feature that allows VRDP shareholders to have their shares purchased by a liquidity provider with whom each Fund has contracted in the event that VRDP Shares are not able to be successfully remarketed. Each Fund is required to redeem any VRDP Shares that are still owned by the liquidity provider after six months of continuous, unsuccessful remarketing. Each Fund pays an annual remarketing fee on the aggregate principal amount of all VRDP Shares outstanding. Each Fund’s VRDP Shares have successfully remarketed since issuance.
NZF’s Series 1 and Series 2 VRDP Shares are considered to be Special Rate VRDP, which are sold to institutional investors. The special rate period will expire on March 1, 2040 for the Fund’s Series 1 and 2 VRDP Shares, but is subject to earlier termination by either the Fund or the holder. During the special rate period, the VRDP Shares will not be remarketed by a remarketing agent, be subject to optional or mandatory tender events, or be supported by a liquidity provider and are not subject to remarketing fees or liquidity fees. During the special rate period, VRDP dividends will be set monthly as a floating rate based on the predetermined formula. Following the initial special rate period, Special Rate Period VRDP Shares may transition to traditional VRDP Shares with dividends set at weekly remarketings, and be supported by designated liquidity provider, or the Board may approve a subsequent special rate period.
Dividends on the VRDP Shares (which are treated as interest payments for financial reporting purposes) are set at a rate established by a remarketing agent; therefore, the market value of the VRDP Shares is expected to approximate its liquidation preference. In the event that VRDP shares are unable to be successfully remarketed, the dividend rate will be the maximum rate which is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the VRDP Shares.
Subject to certain conditions, VRDP Shares may be redeemed, in whole or in part, at any time at the option of each Fund. Each Fund may also redeem certain of the VRDP Shares if the Fund fails to maintain certain asset coverage requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation preference per share plus any accumulated but unpaid dividends.
The average liquidation preference of VRDP Shares outstanding and annualized dividend rate for each Fund during the current fiscal period were as follows:

Fund |  | Average Liquidation Preference of VRDP Shares Outstanding |  |  | Annualized Dividend Rate |
NVG |  | $ | 1,236,600,000 |  |  |  | 3.21% |
NZF |  |  | 679,739,726 |  |  |  | 3.99 |

For financial reporting purposes, the liquidation preference of VRDP Shares is a liability and is recognized as a component of “VRDP Shares, Net” on the Statement of Assets and Liabilities. Unpaid dividends on VRDP Shares are recognized as a component of “Payable for interest” on the Statement of Assets and Liabilities, when applicable. Dividends accrued on VRDP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. Costs incurred by the Funds in connection with their offerings of VRDP Shares were recorded as

7. | Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and 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.
Each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income tax, and in the case of NVG, the AMT applicable to individuals to retain such
tax-exempt
status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.
Each Fund files income tax returns in U.S. federal and applicable state and local jurisdictions. A Fund’s federal income tax returns are generally subject to examination for a period of three fiscal years after being filed. State and local tax returns may be subject to examination for an additional period of time depending on the jurisdiction. Management has analyzed each Fund’s tax positions taken for all open tax years and has concluded that no provision for income tax is required in the Fund’s financial statements.
Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing gains and losses on investment transactions. Temporary differences do not require reclassification. As of year end, permanent differences that resulted in reclassifications among the components of net assets relate primarily to distressed PIK bond adjustments, investments in partnerships, nondeductible expenses, paydowns, reorganization adjustments, taxable market discount, taxes paid, and treatment of notional principal contracts. Temporary and permanent differences have no impact on a Fund’s net assets.
As of year end, the aggregate cost and the net unrealized appreciation/(depreciation) of all investments for federal income tax purposes were as follows:

Fund |  | Tax Cost |  |  | Gross Unrealized Appreciation |  |  | Gross Unrealized (Depreciation) |  |  | Net Unrealized Appreciation (Depreciation) |
NVG |  | $ | 4,649,764,316 |  |  | $ | 99,490,037 |  |  | $ | (560,175,461) |  |  | $ | (460,685,424) |

For purposes of this disclosure, tax cost generally includes the cost of portfolio investments as well as
up-front
fees or premiums exchanged on derivatives and any amounts unrealized for income statement reporting but realized income and/or capital gains for tax reporting, if applicable.

8. | Management Fees and Other Transactions with Affiliates

Management Fees:
Each Fund’s management fee compensates the Adviser for the overall investment advisory and administrative services and general office facilities. The
Sub-Adviser
is compensated for its services to the Funds from the management fees paid to the Adviser.
Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within each individual Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables each Fund’s shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.
The annual fund-level fee, payable monthly, for each Fund is calculated according to the following schedule:

Average Daily Managed Assets* |  | NVG NZF Fund-Level Fee Rate |  |  | NMZ Fund-Level Fee Rate |  |  | NMCO Fund-Level Fee Rate |  |  | NDMO Fund-Level Fee Rate |
For the first $125 million |  |  | 0.5000 | % |  |  | 0.5500 | % |  |  | 0.7500 | % |  |  | 0.7000 | %
For the next $125 million |  |  | 0.4875 |  |  |  | 0.5375 |  |  |  | 0.7375 |  |  |  | 0.6875 |
For the next $250 million |  |  | 0.4750 |  |  |  | 0.5250 |  |  |  | 0.7250 |  |  |  | 0.6750 |
For the next $500 million |  |  | 0.4625 |  |  |  | 0.5125 |  |  |  | 0.7125 |  |  |  | 0.6625 |
For the next $1 billion |  |  | 0.4500 |  |  |  | 0.5000 |  |  |  | 0.7000 |  |  |  | 0.6500 |
For the next $3 billion |  |  | 0.4250 |  |  |  | 0.4750 |  |  |  | 0.6750 |  |  |  | 0.6250 |
For managed assets over $5 billion |  |  | 0.4125 |  |  |  | 0.4625 |  |  |  | 0.6625 |  |  |  | 0.6125 |

The annual complex-level fee, payable monthly, for each Fund is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule by the Funds’ daily managed 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

232

determined amount (originally $2 billion) added to the Nuveen fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011, but do not include certain assets of certain Nuveen funds that were reorganized into funds advised by an affiliate of the Adviser during the 2019 calendar year. As of October 31, 2023, the complex-level fee for each Fund was as follows:

Fund |  | Complex-Level Fee |
NVG |  |  | 0.1623% |
NZF |  |  | 0.1623% |
NMZ |  |  | 0.1623% |
NMCO |  |  | 0.1623% |
NDMO |  |  | 0.1623% |

Other Transactions with Affiliates:
Each 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 Funds engaged in cross-trades pursuant to these procedures as follows:

Fund |  | Purchases |  |  | Sales |  |  | Realized Gain (Loss) |
NVG |  | $ | 3,728,511 |  |  | $ | 3,897,639 |  |  | $ | (236,856) |
NZF |  |  | 10,034,900 |  |  |  | 10,094,300 |  |  |  | (491,098) |
NMZ |  |  | 25,720,055 |  |  |  | 1,404,585 |  |  |  | (141,671) |
NMCO |  |  | 13,693,121 |  |  |  | 4,681,950 |  |  |  | (472,238) |
NDMO |  |  | - |  |  |  | - |  |  |  | - |

9. | Commitments and Contingencies

In the normal course of business, each Fund enters into a variety of agreements that may expose the Fund to some risk of loss. These could include recourse arrangements for certain TOB Trusts and certain agreements related to preferred shares, which are described elsewhere in these Notes to Financial Statements. The risk of future loss arising from such agreements, while not quantifiable, is expected to be remote. As of the end of the reporting period, the Funds did not have any unfunded commitments.
From time to time, the Funds may be party to certain legal proceedings in the ordinary course of business, including proceedings relating to the enforcement of the Funds’ rights under contracts. As of the end of the reporting period, management has determined that any legal proceeding(s) the Funds are subject to, including those described within this report, are unlikely to have a material impact to any of the Funds’ financial statements.

10. | Borrowing Arrangements

Committed Line of Credit:
The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a
364-day,
$2.700 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for temporary purposes (other than ongoing leveraging for investment purposes). Each Participating Fund is allocated a designated proportion of the facility’s capacity (and its associated costs, as described below) based upon a multi-factor assessment of the likelihood and frequency of its need to draw on the facility, the size of the Fund and its anticipated draws, and the potential importance of such draws to the operations and well-being of the Fund, relative to those of the other Funds. A Fund may effect draws on the facility in excess of its designated capacity if and to the extent that other Participating Funds have undrawn capacity. The current credit facility was entered into on June 21, 2023 expiring on June 19, 2024, replacing the previous facility, which expired in June 2023.
The credit facility has the following terms: 0.15% per annum on unused commitment amounts and a drawn interest rate equal to the higher of (a) OBFR (Overnight Bank Funding Rate) plus 1.20% per annum or (b) the Fed Funds Effective Rate plus 1.20% per annum on amounts borrowed. The Participating Funds also incurred a 0.05% upfront fee on the increased commitments from select lenders. Interest expense incurred by the Participating Funds, when applicable, is recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Interest expense and amortization of offering costs” 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 following Funds utilized this facility. Each Fund’s maximum outstanding balance during the utilization period was as follows:
233

Notes to Financial Statements
(continued)

Fund |  | Maximum Outstanding Balance |
NVG |  | $ | 51,100,000 |
NZF |  |  | 82,800,000 |
NMZ |  |  | 47,000,000 |
NMCO |  |  | 18,809,893 |
NDMO |  |  | - |

During the Funds’ utilization period(s) during the current fiscal period, the average daily balance outstanding and average annual interest rate on Borrowings were as follows:

Fund |  | Utilization Period (Days Outstanding) |  |  | Average Daily Balance Outstanding |  |  | Average Annual Interest Rate |
NVG |  |  | 23 |  |  | $ | 26,233,543 |  |  |  | 5.12% |
NZF |  |  | 190 |  |  |  | 25,869,303 |  |  |  | 6.12 |
NMZ |  |  | 63 |  |  |  | 15,513,909 |  |  |  | 5.79 |
NMCO |  |  | 69 |  |  |  | 9,773,524 |  |  |  | 5.86 |
NDMO |  |  | - |  |  |  | - |  |  |  | - |

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

11. | Inter-Fund Borrowing and Lending

Inter-Fund Borrowing and Lending:
The 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 Funds 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, none of the Funds covered by this shareholder report have entered into any inter-fund loan activity.

12. | Fund Mergers

The Mergers as previously described in these Notes to Financial Statements were structured to qualify as
tax-free
reorganizations under the Internal Revenue Code for federal income tax purposes, and the Target Funds’ shareholders recognized no gain or loss for federal income tax purposes as a result. Prior to the closing of each Merger, the Target Funds distributed all of their net investment income and capital gains, if any. Such a distribution may be taxable to the Target Funds’ shareholders for federal income tax purposes.
Investments:
The cost, fair value and net unrealized appreciation (depreciation) of the investments (including investments in derivatives) of the Target Funds as of the date of each Merger, were as follows:
234

|  | NUO |  |  | NKG
Cost of investments |  | $ | 244,285,021 |  |  | $112,066,624
Fair value of investments |  |  | 253,607,985 |  |  | 112,908,007
Net unrealized appreciation (depreciation) of investments |  |  | 9,322,964 |  |  | 841,383

For financial reporting purposes, assets received and shares issued by the Acquiring Fund were recorded at fair value; however, the cost basis of the investments received from the Target Funds were carried forward to align ongoing reporting of the Acquiring Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.
Common Shares:
The common shares outstanding, net assets applicable to common shares and NAV per common share outstanding immediately before and after each Merger were as follows:

Target Fund - Prior to Merger into NZF |  | NUO |  |  | NKG
Common shares outstanding |  |  | 18,254,255 |  |  | 10,399,812
Net assets applicable to common shares |  |  | $269,057,366 |  |  | $122,740,782
NAV per common share outstanding |  |  | $14.74 |  |  | $11.80
Acquiring Fund - Prior to Merger |  |  |  |  | NZF
Common shares outstanding |  |  |  |  |  | 165,390,401
Net assets applicable to common shares |  |  |  |  |  | $2,284,999,614
NAV per common share outstanding |  |  |  |  |  | $13.82
Acquiring Fund - Post Merger |  |  |  |  | NZF
Common shares outstanding |  |  |  |  |  | 193,749,050
Net assets applicable to common shares |  |  |  |  |  | $2,676,797,762
NAV per common share outstanding |  |  |  |  |  | $13.82

Pro Forma Results of Operations:
The beginning of NUO and NKG’s current fiscal period was March 1, 2023 and June 1, 2022, respectively. Assuming the Mergers had been completed on November 1, 2022, the beginning of the Acquiring Fund’s current fiscal period, the pro forma results of operations for the Fund’s current fiscal period, are as follows:

Acquiring Fund - Pro Forma Results from Operations |  | NZF
Net investment income (loss) |  | $102,811,769
Net realized and unrealized gains (losses) |  | (70,279,409)
Change in net assets resulting from operations |  | 32,532,360

Because the combined investment portfolio of each Merger has been managed as a single integrated portfolio since each Merger was completed, it is not practicable to separate the amounts of revenue and earnings of each Target Fund that have been included in the Statement of Operations of the Acquiring Fund since each Merger was consummated.
Cost and Expenses:
In connection with each Merger, the Acquiring Fund incurred certain associated costs and expenses. Such amounts were included as components of “Accrued other expenses” on the Statement of Assets and Liabilities and “Reorganization/Merger expenses” on the Statement of Operations.

13. | Subsequent Event

Preferred Shares for NMCO:
During November 2023, NMCO redeemed 150 of Series C MFP Shares ($15,000,000 liquidation preference).
Updated Distribution Policy:
As noted in the Common Share information section of this report, effective with distributions payable on December 1, 2023 (December 29, 2023 for NDMO), each Fund’s distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to shareholders of its best estimate of the distribution sources at that the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’
1099-DIV
forms after the end of the year.

CURRENT INVESTMENT OBJECTIVES, INVESTMENT POLICIES AND PRINCIPAL RISKS OF THE FUNDS
NUVEEN
AMT-FREE
MUNICIPAL CREDIT INCOME FUND (NVG)
Investment Objectives
The Fund’s investment objectives are to provide current income exempt from regular federal income tax and federal alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market by investing
in tax-exempt municipal
bonds that the Fund’s investment adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued.
Investment Policies
As a fundamental investment policy, under normal circumstances, the Fund will invest at least 80% of its Assets (as defined below) in municipal securities and other related investments, the income from which is exempt from regular federal income taxes.
As
a non-fundamental investment
policy, under normal circumstances, the Fund will invest 100% of its Managed Assets (as defined below) and at least 80% of its Assets in municipal securities and other related investments, the income from which is also exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.
“Assets” mean the net assets of the Fund plus the amount of any borrowings for investment purposes. “Managed Assets” mean the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.
Under normal circumstances:

| · |  | The Fund may invest up to 55% of its Managed Assets in securities that, at the time of investment, are rated below the three highest grades (Baa or BBB or lower) by at least one nationally recognized statistical rating organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Fund’s sub-adviser.

| · |  | The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities.

| · |  | The Fund may not enter into a futures contract or related options or forward contracts if more than 30% of the Fund’s Managed Assets would be represented by futures contracts or more than 5% of the Fund’s Managed Assets would be committed to initial margin deposits and premiums on futures contracts or related options.

| · |  | The Fund will generally maintain an investment portfolio with an overall weighted average maturity of greater than 10 years.

The foregoing policies apply only at the time of any new investment.
Approving Changes in Investment Policies
The Board of Trustees of the Fund may change the policies described above without a shareholder vote. However, with respect to the Fund’s policy of investing at least 80% of its Assets in municipal securities and other related investments that pay interest exempt from both regular federal income tax and the federal alternative minimum tax applicable to individuals at the time of purchase, such policy may not be changed without 60 days’ prior written notice and the approval of the holders of a majority of the outstanding common shares and preferred shares voting together as a single class, and the approval of the holders of a majority of the outstanding preferred shares, voting separately as a single class. A “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy or (ii) more than 50% of the shares, whichever is less.
Portfolio Contents
The Fund generally invests in municipal securities. Municipal securities include municipal bonds, notes, securities issued to finance and refinance public projects, certificates of participation, variable rate demand obligations, lease obligations, municipal notes,
pre-refunded
municipal bonds, private activity bonds, securities issued by tender option bond trusts (“TOB Trusts”), including inverse floating rate securities, and other forms of municipal bonds and securities, and other related instruments that create exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular U.S. federal income tax.
Municipal securities are debt obligations generally issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam) to finance or refinance public purpose projects such as roads, schools, and water supply systems.
The Fund may invest in municipal securities that represent lease obligations and certificates of participation in such leases. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities. Income from such obligations generally is exempt from state and local taxes in the state of issuance. A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates typically are issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under
237

Shareholder Update
(Unaudited) (continued)
such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the Fund’s participation interest in the underlying municipal securities, plus accrued interest.
The Fund may invest in municipal notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes.
The Fund may invest in “tobacco settlement bonds.” Tobacco settlement bonds are municipal securities that are secured or payable solely from the collateralization of the proceeds from class action or other litigation against the tobacco industry.
The Fund may invest in
pre-refunded
municipal securities. The principal of and interest
on pre-refunded municipal
securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as
the pre-refunded municipal
securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for
the pre-refunded municipal
securities. However, except for a change in the revenue source from which principal and interest payments are made,
the pre-refunded municipal
securities remain outstanding on their original terms until they mature or are redeemed by the issuer.
The Fund may invest in private activity bonds. Private activity bonds are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues.
The Fund may invest in municipal securities issued by special taxing districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities.
The Fund may invest in inverse floating rate securities issued by a TOB trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a TOB trust) formed by a third party sponsor for the purpose of holding municipal bonds. Inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate on the municipal bond held by the TOB trust, which effectively leverages the Fund’s investment.
The Fund may invest in floating rate securities issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.
The Fund may invest in zero coupon bonds. A zero coupon bond is a bond that typically does not pay interest for the entire life of the obligation or for an initial period after the issuance of the obligation.
The Fund may buy and sell securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date.
The Fund may invest in illiquid securities (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), and repurchase agreements with maturities in excess of seven days.
238

The Fund may enter into certain derivative instruments in pursuit of its investment objectives, including to seek to enhance return, to hedge certain risks of its investments in municipal securities or as a substitute for a position in the underlying asset. Such instruments include financial futures contracts, swap contracts (including interest rate swaps, credit default swaps and municipal market data rate locks (“MMD Rate Locks”)), options on financial futures, options on swap contracts or other derivative instruments.
The Fund may purchase and sell MMD Rate Locks. An MMD Rate Lock permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Fund can create a synthetic long or short position, allowing the Fund to select what the manager believes is an attractive part of the yield curve. The Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain or to increase the Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates).
The Fund may also invest in securities of other open-
or closed-end investment
companies (including exchange-traded funds (“ETFs”)) that invest primarily in municipal securities of the types in which the Fund may invest directly, to the extent permitted by the Investment Company Act of 1940, as amended (the “1940 Act”), the rules and regulations issued thereunder and applicable exemptive orders issued by the Securities and Exchange Commission (“SEC”).
Use of Leverage
The Fund uses leverage to pursue its investment objectives. The Fund may use leverage to the extent permitted by the 1940 Act. The Fund may source leverage through a number of methods including the issuance of preferred shares of beneficial interest (“Preferred Shares”), entering into reverse repurchase agreements (effectively a secured borrowing) and borrowings (for defensive purposes only). In addition, the Fund may also use certain derivatives that have the economic effect of leverage by creating additional investment exposure. The amount and sources of leverage will vary depending on market conditions.
Temporary Defensive Periods
During temporary defensive periods (e.g., times when, in the Fund’s investment adviser’s and/or the Fund’s
sub-adviser’s opinion,
temporary imbalances of supply and demand or other temporary dislocations in
the tax-exempt bond
market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to keep the Fund’s cash fully invested, the Fund may invest any percentage of its Managed Assets in short-term investments including high quality, short-term debt securities that may be
either tax-exempt or
taxable. The Fund may not achieve its investment objectives during such periods.

Municipal securities are debt obligations generally issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam) to finance or refinance public purpose projects such as roads, schools, and water supply systems.
The Fund may also invest in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to noncorporate taxpayers (“AMT Bonds”). AMT Bonds may trigger adverse tax consequences for Fund shareholders who are subject to the federal alternative minimum tax.
The Fund may invest in municipal securities that represent lease obligations and certificates of participation in such leases. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities.

Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes.
The Fund may invest in “tobacco settlement bonds.” Tobacco settlement bonds are municipal securities that are secured or payable solely from the collateralization of the proceeds from class action or other litigation against the tobacco industry.
The Fund may invest in
pre-refunded
municipal securities. The principal of and interest
on pre-refunded municipal
securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as
the pre-refunded municipal
securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for
the pre-refunded municipal
securities. However, except for a change in the revenue source from which principal and interest payments are made,
the pre-refunded municipal
securities remain outstanding on their original terms until they mature or are redeemed by the issuer.
The Fund may invest in private activity bonds. Private activity bonds are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues.
The Fund may invest in municipal securities issued by special taxing districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities.
The Fund may invest in inverse floating rate securities issued by a TOB trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a TOB trust) formed by a third party sponsor for the purpose of holding municipal bonds. Inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate on the municipal bond held by the TOB trust, which effectively leverages the Fund’s investment.
The Fund may invest in floating rate securities issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.
The Fund may invest in zero coupon bonds. A zero coupon bond is a bond that typically does not pay interest for the entire life of the obligation or for an initial period after the issuance of the obligation.
The Fund may buy and sell securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date.
The Fund may invest in illiquid securities (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the 1933 Act, and repurchase agreements with maturities in excess of seven days.
244

The Fund may enter into certain derivative instruments in pursuit of its investment objective, including to seek to enhance return, to hedge certain risks of its investments in municipal securities or as a substitute for a position in the underlying asset. Such instruments include financial futures contracts, swap contracts (including interest rate swaps, credit default swaps and MMD Rate Locks), options on financial futures, options on swap contracts, or other derivative instruments.
The Fund may purchase and sell MMD Rate Locks. An MMD Rate Lock permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Fund can create a synthetic long or short position, allowing the Fund to select what the manager believes is an attractive part of the yield curve. The Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain or to increase the Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates).
The Fund may also invest in securities of other open-
or closed-end investment
companies (including ETFs) that invest primarily in municipal securities of the types in which the Fund may invest directly, to the extent permitted by the 1940 Act, the rules and regulations issued thereunder and applicable exemptive orders issued by the SEC.
Use of Leverage
The Fund uses leverage to pursue its investment objectives. The Fund may use leverage to the extent permitted by the 1940 Act. The Fund may source leverage through a number of methods including the issuance of Preferred Shares, investments in inverse floating rate securities, entering into reverse repurchase agreements (effectively a secured borrowing) and borrowings (subject to certain investment restrictions). In addition, the Fund may also use certain derivatives that have the economic effect of leverage by creating additional investment exposure. The amount and sources of leverage will vary depending on market conditions.
Temporary Defensive Periods
During temporary defensive periods (e.g., times when, in the Fund’s investment adviser’s and/or the Fund’s
sub-adviser’s opinion,
temporary imbalances of supply and demand or other temporary dislocations in
the tax-exempt bond
market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to keep the Fund’s cash fully invested, the Fund may invest any percentage of its Managed Assets in short-term investments including high quality, short-term debt securities that may be
either tax-exempt or
taxable. The Fund may not achieve its investment objectives during such periods.

Investment Objectives
The Fund’s primary investment objective is to provide a high level of current income exempt from regular U.S. federal income tax. The Fund’s secondary investment objective is to seek total return.
Investment Policies
Under normal circumstances, the Fund will invest at least 80% of its Assets (as defined below) in municipal securities, the income from which is exempt from regular U.S. federal income taxes.
“Assets” mean the net assets of the Fund plus the amount of any borrowings for investment purposes. “Managed Assets” mean the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.
Under normal circumstances:

| · |  | The Fund may invest without limit in high yielding, low- to medium-quality municipal securities (low- to medium-quality municipal securities are municipal securities rated Baa/BBB or lower) rated by at least one NRSRO at the time of investment or are unrated but judged by the Fund’s sub-adviser to be of comparable quality.

| · |  | The Fund may invest no more than 30% of its Managed Assets in municipal securities that, at the time of investment, either are rated CCC+/ Caa1 or lower, or are unrated but judged by the Fund’s sub-adviser to be of comparable quality.

| · |  | The Fund may invest no more than 10% of its Managed Assets in defaulted securities or in the securities of an issuer that is in bankruptcy or insolvency proceedings.

The foregoing policies apply only at the time of any new investment.
Approving Changes in Investment Policies
The Board of Trustees of the Fund may change the policies described above without a shareholder vote. However, with respect to the Fund’s policy of investing at least 80% of its Assets in municipal securities, the income from which is exempt from regular U.S. federal income taxes, such policy may not be changed without 60 days’ prior written notice and the approval of the holders of a majority of the outstanding common shares and preferred shares voting together as a single class, and the approval of the holders of a majority of the outstanding preferred shares, voting separately as a single class. A “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy or (ii) more than 50% of the shares, whichever is less.
Portfolio Contents
The Fund generally invests in municipal securities. Municipal securities include municipal bonds, notes, securities issued to finance and refinance public projects, certificates of participation, variable rate demand obligations, lease obligations, municipal notes,
pre-refunded
municipal bonds, private activity bonds, securities issued by TOB Trusts, including inverse floating rate securities, and other forms of municipal bonds and securities, and other related instruments that create exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular U.S. federal income tax.
Municipal securities are debt obligations generally issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam) to finance or refinance public purpose projects such as roads, schools, and water supply systems.
The Fund may invest in municipal securities that are additionally secured by insurance, bank credit agreements or escrow accounts.
The Fund may invest in municipal securities that represent lease obligations and certificates of participation in such leases. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities. Income from such obligations generally is exempt from state and local taxes in the state of issuance. A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates typically are issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the Fund’s participation interest in the underlying municipal securities, plus accrued interest.
The Fund may invest in municipal notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds

Investment Objective
The Fund’s investment objective is to seek total return through income exempt from regular federal income taxes and capital appreciation.
Investment Policies
Under normal circumstances, the Fund will invest at least 80% of its Assets (as defined below) in municipal securities, the income from which is exempt from regular federal income taxes.
“Assets” means net assets of the Fund plus the amount of any borrowings for investment purposes. “Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.
Under normal circumstances:

| · |  | The Fund may invest up to 20% of its Managed Assets in taxable debt obligations, including taxable municipal securities and corporate debt securities.

| · |  | The Fund may invest no more than 10% of its Managed Assets in defaulted securities or in the securities of an issuer that is in bankruptcy or insolvency proceedings. This policy does not apply in connection with any workout of an issuer of a debt security that the Fund already owns.

The foregoing policies apply only at the time of any new investment.
Approving Changes in Investment Policies
The Board of Trustees of the Fund may change the policies described above without a shareholder vote. However, with respect to the Fund’s fundamental investment policy of investing at least 80% of its Assets in municipal securities, the income from which is exempt from regular federal income taxes, such policy may not be changed without 60 days’ prior written notice and the approval of the holders of a majority of the outstanding common shares and preferred shares voting together as a single class, and the approval of the holders of a majority of the outstanding preferred shares, voting separately as a single class.

The Fund generally invests its assets in a portfolio of municipal securities of any credit quality and maturity. Municipal securities include municipal bonds, notes, securities issued to finance and refinance public projects, certificates of participation, variable rate demand obligations, lease obligations, municipal notes,
pre-refunded
municipal bonds, private activity bonds, securities issued by TOB Trusts, including inverse floating rate securities, and other forms of municipal bonds and securities, and other related instruments that create exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular U.S. federal income tax.

The Fund may invest in municipal securities that are additionally secured by insurance, bank credit agreements or escrow accounts.
The Fund may also invest in AMT Bonds. AMT Bonds may trigger adverse tax consequences for Fund shareholders who are subject to the federal alternative minimum tax.
The Fund may invest in municipal securities that represent lease obligations and certificates of participation in such leases. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities.

The Fund may invest in “tobacco settlement bonds.” Tobacco settlement bonds are municipal securities that are secured or payable solely from the collateralization of the proceeds from class action or other litigation against the tobacco industry.
The Fund may invest in corporate debt securities. Corporate debt securities are fully taxable debt obligations issued by corporations. The broad category of corporate debt securities includes debt issued by companies of all kinds, including those with small-,
mid-
and large-capitalizations. Corporate debt may be rated investment-grade or below investment-grade and may carry variable or floating rates of interest. Corporate debt securities are fixed income securities issued by businesses to finance their operations, although corporate debt instruments may also include bank loans to companies. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured.
The Fund may invest in inverse floating rate securities issued by a TOB trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a TOB trust) formed by a third party sponsor for the purpose of holding municipal bonds.

The Fund may invest in floating rate securities issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.
The Fund may invest in zero coupon bonds. A zero coupon bond is a bond that typically does not pay interest for the entire life of the obligation or for an initial period after the issuance of the obligation.
The Fund may buy and sell securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date.
The Fund may invest in illiquid securities (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the 1933 Act, and repurchase agreements with maturities in excess of seven days.
250

The Fund may invest without limitation in credit default swaps, and may enter into credit default swaps as either a buyer or a seller. The credit default swaps in which the Fund may invest (or sell) include those in which the underlying reference instrument is the debt obligation of a single reference issuer (“single-name CDS”). Unlike other types of credit default swaps, single-name CDS do not have the benefit of diversification across many issuers.
In addition to credit default swaps, the Fund may enter into certain derivative instruments in pursuit of its investment objective, including to seek to enhance return, to hedge certain risks of its investments in municipal securities, to attempt to manage the effective maturity or duration of securities in the Fund’s portfolio or as a substitute for a position in the underlying asset. Such instruments include financial futures contracts, swap contracts (including interest rate swaps, credit default swaps and MMD Rate Locks), options on financial futures, options on swap contracts or other derivative instruments.
The Fund may purchase and sell MMD Rate Locks. An MMD Rate Lock permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Fund can create a synthetic long or short position, allowing the Fund to select what the manager believes is an attractive part of the yield curve. The Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain or to increase the Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates).
The Fund may also invest in securities of other open-
or closed-end investment
companies (including ETFs) that invest primarily in municipal securities of the types in which the Fund may invest directly, to the extent permitted by the 1940 Act, the rules and regulations issued thereunder and applicable exemptive orders issued by the SEC.
Use of Leverage
The Fund uses leverage to pursue its investment objective. The Fund may use leverage to the extent permitted by the 1940 Act. The Fund may source leverage through a number of methods including through borrowings, issuing Preferred Shares, the issuance of debt securities, entering into reverse repurchase agreements (effectively a borrowing), and investments in inverse floating rate securities. In addition, the Fund may also use certain derivatives that have the economic effect of leverage by creating additional investment exposure. The amount and sources of leverage will vary depending on market conditions.
Temporary Defensive Periods
During temporary defensive periods or in order to help keep the Fund’s assets fully invested, including during the period within which the net proceeds of an offering of Securities are first being invested, the Fund may deviate from its investment policies and objectives. During such periods, the Fund may invest any percentage of its Managed Assets in short-term investments, including high quality, short-term debt securities that may be either
tax-exempt
or taxable. The Fund may not achieve its investment objectives during such periods.

Shareholder Update
(Unaudited) (continued)
Portfolio Level Risks:
Alternative Minimum Tax Risk.
The Fund may invest in AMT Bonds. Therefore, a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.
Below Investment Grade Risk.
Investments of below investment grade quality are regarded as having speculative characteristics with respect to the issuer’s capacity to pay dividends or interest and repay principal, and may be subject to higher price volatility and default risk than investment grade investments of comparable terms and duration. Issuers of lower grade investments may be highly leveraged and may not have available to them more traditional methods of financing. The prices of these lower grade investments are typically more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn. The secondary market for lower rated investments may not be as liquid as the secondary market for more highly rated investments, a factor which may have an adverse effect on the Fund’s ability to dispose of a particular investment. If a below investment grade security goes into default, or its issuer enters bankruptcy, it might be difficult to sell that security in a timely manner at a reasonable price.
Call Risk.
The Fund may invest in municipal securities that are subject to call risk. Such municipal securities may be redeemed at the option of the issuer, or “called,” before their stated maturity or redemption date. In general, an issuer will call its instruments if they can be refinanced by issuing new instruments that bear a lower interest rate. The Fund is subject to the possibility that during periods of falling interest rates, an issuer will call its high yielding municipal securities. The Fund would then be forced to invest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.
Credit Risk.
Issuers of municipal securities in which the Fund may invest may default on their obligations to pay principal or interest when due. This
non-payment
would result in a reduction of income to the Fund, a reduction in the value of a municipal security experiencing
non-payment
and potentially a decrease in the net asset value (“NAV”) of the Fund. To the extent that the credit rating assigned to a municipal security in the Fund’s portfolio is downgraded, the market price and liquidity of such security may be adversely affected.
Credit Spread Risk.
Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market believes that municipal securities generally have a greater risk of default. Increasing credit spreads may reduce the market values of the Fund’s securities. Credit spreads often increase more for lower rated and unrated securities than for investment grade securities. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity securities.
Debt Securities Risk.
Issuers of debt instruments in which the Fund may invest may default on their obligations to pay principal or interest when due. This
non-payment
would result in a reduction of income to the Fund, a reduction in the value of a debt instrument experiencing
non-payment
and, potentially, a decrease in the NAV of the Fund. There can be no assurance that liquidation of collateral would satisfy the issuer’s obligation in the event of
non-payment
of scheduled interest or principal or that such collateral could be readily liquidated. In the event of bankruptcy of an issuer, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a security. To the extent that the credit rating assigned to a security in the Fund’s portfolio is downgraded, the market price and liquidity of such security may be adversely affected.
Distressed or Defaulted Securities Risk.
Investments in “distressed” securities, meaning those whose issuers are experiencing financial difficulties or distress at the time of acquisition, present a substantial risk of future default. In the event distressed securities become defaulted securities or the Fund otherwise holds defaulted securities, the Fund may incur losses, including additional expenses, to the extent it is required to seek recovery upon a default in the payment of principal or interest on those securities. In any reorganization or liquidation proceeding relating to a portfolio security, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Defaulted or distressed securities may be subject to restrictions on resale.
Deflation Risk.
Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.
Derivatives Risk.
The use of derivatives involves additional risks and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivative instruments can be used to acquire or to transfer the risk and returns of a municipal security or other asset without buying or selling the municipal security or asset. These instruments may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. An
over-the-counter
derivative transaction between the Fund and a counterparty that is not cleared through a central counterparty also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. The payment obligation for a cleared derivative transaction is guaranteed by a central counterparty, which exposes the Fund to the creditworthiness of the central counterparty. The use of certain derivatives involves leverage, which can cause the Fund’s portfolio to be more volatile than if the portfolio had not been leveraged. Leverage can significantly magnify the effect of price movements of the reference asset, disproportionately increasing the Fund’s losses and reducing the Fund’s opportunities for gains when the reference asset changes in unexpected ways. In some instances, such leverage could result in losses that exceed the original amount invested.
It is possible that regulatory or other developments in the derivatives market, including changes in government regulation, could adversely impact the Fund’s ability successfully use derivative instruments.
Duration Risk.
Duration is the sensitivity, expressed in years, of the price of a
fixed-income
security to changes in the general level of interest rates (or yields). Securities
with
longer durations tend to be more sensitive to interest rate (or yield) changes, which typically corresponds to increased volatility and risk, than securities with shorter durations. For example, if a security or portfolio has a duration of three years and interest rates increase
254

by 1%, then the security or portfolio would decline in value by approximately 3%. Duration differs from maturity in that it considers potential changes to interest rates, and a security’s coupon payments, yield, price and par value and call features, in addition to the amount of time until the security matures. The duration of a security will be expected to change over time with changes in market factors and time to maturity.
Economic Sector Risk.
The Fund may invest a significant amount of its total assets in municipal securities in the same economic sector. This may make the Fund more susceptible to adverse economic, political or regulatory occurrences affecting an economic sector making the Fund more vulnerable to unfavorable developments in that sector than funds that invest more broadly. As the percentage of the Fund’s Managed Assets invested in a particular sector increases, so does the potential for fluctuation in the value of the Fund’s assets. In addition, the Fund may invest a significant portion of its assets in certain sectors of the municipal securities market, such as health care facilities, private educational facilities, special taxing districts and
start-up
utility districts, and private activity bonds including industrial development bonds on behalf of transportation companies, whose credit quality and performance may be more susceptible to economic, business, political, regulatory and other developments than other sectors of municipal issuers. If the Fund invests a significant portion of its assets in one or more particular sectors, the Fund’s performance may be subject to additional risk and variability.
Financial Futures and Options Transactions Risk.
The Fund may use certain transactions for hedging the portfolio’s exposure to credit risk and the risk of increases in interest rates, which could result in poorer overall performance for the Fund. There may be an imperfect correlation between price movements of the futures and options and price movements of the portfolio securities being hedged.
If the Fund engages in futures transactions or in the writing of options on futures, it will be required to maintain initial margin and maintenance margin and may be required to make daily variation margin payments in accordance with applicable rules of the exchanges and the Commodity Futures Trading Commission (“CFTC”). If the Fund purchases a financial futures contract or a call option or writes a put option in order to hedge the anticipated purchase of municipal securities, and if the Fund fails to complete the anticipated purchase transaction, the Fund may have a loss or a gain on the futures or options transaction that will not be offset by price movements in the municipal securities that were the subject of the anticipatory hedge. There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a derivatives or futures or a futures option position, and the Fund would remain obligated to meet margin requirements until the position is closed.
Hedging Risk.
The Fund’s use of derivatives or other transactions to reduce risk involves costs and will be subject to the investment adviser’s and/or the
sub-adviser’s
ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that the investment adviser’s and/or the
sub-adviser’s
judgment in this respect will be correct, and no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so. Hedging activities may reduce the Fund’s opportunities for gain by offsetting the positive effects of favorable price movements and may result in net losses.
Illiquid Investments Risk.
Illiquid investments are investments that are not readily marketable. These investments may include restricted investments, including Rule 144A securities, which cannot be resold to the public without an effective registration statement under the 1933 Act, or, if they are unregistered may be sold only in a privately negotiated transaction or pursuant to an available exemption from registration. The Fund may not be able to readily dispose of such investments at prices that approximate those at which the Fund could sell such investments if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of investments, thereby adversely affecting the Fund’s NAV and ability to make dividend distributions. The financial markets in general have in recent years experienced periods of extreme secondary market supply and demand imbalance, resulting in a loss of liquidity during which market prices were suddenly and substantially below traditional measures of intrinsic value. During such periods, some investments could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time.
Income Risk.
The Fund’s income could decline due to falling market interest rates. This is because, in a falling interest rate environment, the Fund generally will have to invest the proceeds from maturing portfolio securities in lower-yielding securities.
Inflation Risk.
Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the common shares and distributions can decline. Currently, inflation rates are elevated relative to normal market conditions and could increase.
Insurance Risk.
The Fund may purchase municipal securities that are secured by insurance, bank credit agreements or escrow accounts. The credit quality of the companies that provide such credit enhancements will affect the value of those securities. Certain significant providers of insurance for municipal securities have incurred significant losses as a result of exposure to
sub-prime
mortgages and other lower credit quality investments. As a result, such losses reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the value of the municipal security would more closely, if not entirely, reflect such rating. In such a case, the value of insurance associated with a municipal security may not add any value. The insurance feature of a municipal security does not guarantee the full payment of principal and interest through the life of an insured obligation, the market value of the insured obligation or the NAV of the common shares represented by such insured obligation.
Interest Rate Risk.
Interest rate risk is the risk that municipal securities in the Fund’s portfolio will decline in value because of changes in market interest rates. Generally, when market interest rates rise, the market value of such securities will fall, and vice versa. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of municipal securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change.
255

Shareholder Update
(Unaudited) (continued)
Inverse Floating Rate Securities Risk.
The Fund may invest in inverse floating rate securities. In general, income on inverse floating rate securities will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal. In addition, inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate, which effectively leverages the Fund’s investment. As a result, the market value of such securities generally will be more volatile than that of fixed rate securities.
The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.
The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

| · |  | If the Fund has a need for cash and the securities in a special purpose trust are not actively trading due to adverse market conditions;

| · |  | If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding special purpose trusts; and

| · |  | If the value of an underlying security declines significantly and if additional collateral has not been posted by the Fund.

Municipal Securities Market Liquidity Risk.
Inventories of municipal securities held by brokers and dealers have decreased in recent years, lessening their ability to make a market in these securities. This reduction in market making capacity has the potential to decrease the Fund’s ability to buy or sell municipal securities at attractive prices, and increase municipal security price volatility and trading costs, particularly during periods of economic or market stress. In addition, recent federal banking regulations may cause certain dealers to reduce their inventories of municipal securities, which may further decrease the Fund’s ability to buy or sell municipal securities. As a result, the Fund may be forced to accept a lower price to sell a security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of municipal securities to raise cash to meet its obligations, those sales could further reduce the municipal securities’ prices and hurt performance.
Municipal Securities Market Risk.
The amount of public information available about the municipal securities in the Fund’s portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of the
sub-adviser
than if the Fund were a stock fund or taxable bond fund. The secondary market for municipal securities, particularly below investment grade municipal securities, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its municipal securities at attractive prices.
Other Investment Companies Risk.
The Fund may invest in the securities of other investment companies, including ETFs. Investing in an investment company exposes the Fund to all of the risks of that investment company’s investments. The Fund, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies’ expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations. As a result, the cost of investing in investment company shares may exceed the costs of investing directly in its underlying investments. In addition, securities of other investment companies may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities and therefore magnify the Fund’s leverage risk.
With respect to ETF’s, an ETF that is based on a specific index may not be able to replicate and maintain exactly the composition and relative weighting of securities in the index. The value of an ETF based on a specific index is subject to change as the values of its respective component assets fluctuate according to market volatility. ETFs typically rely on a limited pool of authorized participants to create and redeem shares, and an active trading market for ETF shares may not develop or be maintained. The market value of shares of ETFs and
closed-end
funds may differ from their NAV.
Puerto Rico Municipal Securities Market Risk.
To the extent that the Fund invests a significant portion of its assets in the securities issued by the Commonwealth of Puerto Rico or its political subdivisions, agencies, instrumentalities, or public corporations (collectively referred to
as “Puerto Rico” or the “Commonwealth”), it will be disproportionally affected by political, social and economic conditions and developments in the Commonwealth. In addition, economic, political or regulatory changes in that territory could adversely affect the value of the Fund’s investment portfolio.
Puerto Rico currently is experiencing significant fiscal and economic challenges, including substantial debt service obligations, high levels of unemployment, underfunded public retirement systems, and persistent government budget deficits. These challenges may negatively affect the value of the Fund’s investments in Puerto Rican municipal securities. Several major ratings agencies have downgraded the general obligation debt of Puerto Rico to below investment grade and continue to maintain a negative outlook for this debt, which increases the likelihood that the rating will be lowered further. Puerto Rico recently defaulted on its debt by failing to make full payment due on its outstanding bonds, and there can be no assurance that Puerto Rico will be able to satisfy its future debt obligations. Further downgrades or defaults may place additional strain on the Puerto Rico economy and may negatively affect the value, liquidity, and volatility of the Fund’s investments in Puerto Rican municipal securities. Additionally, numerous issuers have entered Title III of the Puerto Rico Oversite, Management and Economic Stability Act (“PROMESA”), which is similar to bankruptcy protection, through which the Commonwealth of Puerto Rico can restructure its debt. However, Puerto Rico’s case is the first ever heard under PROMESA and there is no existing case precedent to guide the proceedings. Accordingly, Puerto Rico’s debt restructuring process could take significantly longer than traditional municipal bankruptcy proceedings. Further, it is not clear whether a debt restructuring process will ultimately be approved or, if so, the extent to which it will apply to Puerto Rico municipal securities sold by an issuer other than the territory. A debt restructuring could reduce the principal amount due, the interest rate, the maturity, and other terms of Puerto Rico municipal securities, which could adversely affect the value of Puerto Rican municipal securities. Legislation that would allow Puerto Rico to restructure its municipal debt obligations, thus increasing the risk that Puerto Rico may never pay off municipal indebtedness, or may pay only a small fraction of the amount owed, could also impact the value of the Fund’s investments in Puerto Rican municipal securities.
256

These challenges and uncertainties have been exacerbated by multiple hurricanes and the resulting natural disasters that
have
stuck Puerto Rico since 2017. The full extent of the natural disasters’ impact on Puerto Rico’s economy and foreign investment in Puerto Rico is difficult to estimate.
Reinvestment Risk.
Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called municipal securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the common shares’ market price, NAV and/or a common shareholder’s overall returns.
Special Risks Related to Certain Municipal Obligations.
Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of
“non-appropriation”
clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event that the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of
non-appropriation
or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover the Fund’s original investment. In the event of
non-appropriation,
the issuer would be in default and taking ownership of the assets may be a remedy available to the Fund, although the Fund does not anticipate that such a remedy would normally be pursued.
Certificates of participation involve the same risks as the underlying municipal leases. In addition, the Fund may be dependent upon the municipal authority issuing the certificates of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.
Swap Transactions Risk.
The Fund may enter into debt-related derivative instruments such as credit default swap contracts and interest rate swaps. Like most derivative instruments, the use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of swaps requires an understanding by the adviser and/or the
sub-adviser
of not only the referenced asset, rate or index, but also of the swap itself. If the investment adviser and/or the
sub-adviser
is incorrect in its forecasts of default risks, market spreads or other applicable factors or events, the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used.
Tax Risk.
The value of the Fund’s investments and its NAV may be adversely affected by changes in tax rates, rules and policies. Because interest income from municipal securities is normally not subject to regular federal income taxation, the attractiveness of municipal securities in relation to other investment alternatives is affected by changes in federal income tax rates or changes in the tax exempt status of interest income from municipal securities. Additionally, the Fund is not a suitable investment for individual retirement accounts, for other tax exempt or
tax-deferred
accounts, for investors who are not sensitive to the federal income tax consequences of their investments.
Taxability Risk.
The Fund will invest in municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for regular federal income tax purposes, and the
sub-adviser
will not independently verify that opinion. Subsequent to the Fund’s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid, taxable income. As a result, the treatment of dividends previously paid or to be paid by the Fund as “exempt-interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased federal income tax liabilities. Certain other investments made by the Fund, including derivatives transactions, may result in the receipt of taxable income or gains by the Fund.
Tobacco Settlement Bond Risk.
The Fund may invest in tobacco settlement bonds. Tobacco settlement bonds are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement, an agreement between 46 states and nearly all of the U.S. tobacco manufacturers (the “MSA”). Under the terms of the MSA, the actual amount of future settlement payments by tobacco-manufacturers is dependent on many factors, including, among other things, reduced cigarette consumption. Payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline.
Unrated Securities Risk.
The Fund may purchase securities that are not rated by any rating organization. Unrated securities determined by the Fund’s investment adviser to be of comparable quality to rated investments which the Fund may purchase may pay a higher dividend or interest rate than such rated investments and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated investments or issuers than rated investments or issuers. Some unrated securities may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. To the extent that the Fund invests in unrated securities, the Fund’s ability to achieve its investment objectives will be more dependent on the investment adviser’s credit analysis than would be the case when the Fund invests in rated securities.
Valuation Risk.
The municipal securities in which the Fund invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. Pricing services generally price municipal securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund were to change pricing services, or if the Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s NAV.
257

Shareholder Update
(Unaudited) (continued)
Zero Coupon Bonds Risk.
Because interest on zero coupon bonds is not paid on a current basis, the values of zero coupon bonds will be more volatile in response to interest rate changes than the values of bonds that distribute income regularly. Although zero coupon bonds generate income for accounting purposes, they do not produce cash flow, and thus the Fund could be forced to liquidate securities at an inopportune time in order to generate cash to distribute to shareholders as required by tax laws.
Fund Level and Other Risks:
Anti-Takeover Provisions.
The Fund’s organizational documents include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to
open-end
status, which include those commonly known as “Control Share Acquisition” provisions. Although the application of the “Control Share Acquisition” provisions has currently been suspended, these provisions could have the effect of depriving the common shareholders of opportunities to sell their common shares at a premium over the then-current market price of the common shares.
Borrowing Risk.
In addition to borrowing for leverage, the Fund may borrow for temporary or emergency purposes, to pay dividends, repurchase its shares, or clear portfolio transactions. Borrowing may exaggerate changes in the NAV of the Fund’s shares and may affect the Fund’s net income. When the Fund borrows money, it must pay interest and other fees, which will reduce the Fund’s returns if such costs exceed
the
returns on the portfolio securities purchased or retained with such borrowings. Any such borrowings are intended to be temporary. However, under certain market circumstances, such borrowings might be outstanding for longer periods of time.
Counterparty Risk.
Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have incurred or may incur in the future significant financial hardships including bankruptcy and losses as a result of exposure to
sub-prime
mortgages and other lower-quality credit investments. As a result, such hardships have reduced these entities’ capital and called into question their continued ability to perform their obligations under such transactions. By using such derivatives or other transactions, the Fund assumes the risk that its counterparties could experience similar financial hardships. In the event of the insolvency of a counterparty, the Fund may sustain losses or be unable to liquidate a derivatives position.
Cybersecurity Risk.
The Fund and its service providers are susceptible to operational and information security risk resulting from cyber incidents. Cyber incidents refer to both intentional attacks and unintentional events including: processing errors, human errors, technical errors including computer glitches and system malfunctions, inadequate or failed internal or external processes, market-wide technical-related disruptions, unauthorized access to digital systems (through “hacking” or malicious software coding), computer viruses, and cyber-attacks which shut down, disable, slow or otherwise disrupt operations, business processes or website access or functionality (including denial of service attacks). Cyber incidents could adversely impact the Fund and cause the Fund to incur financial loss and expense, as well as face exposure to regulatory penalties, reputational damage, and additional compliance costs associated with corrective measures. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund.
Economic and Political Events Risk.
The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the municipal securities of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds). Such developments may adversely affect a specific industry or local political and economic conditions, and thus may lead to declines in the creditworthiness and value of such municipal securities.
Fund Tax Risk.
The Fund has elected to be treated and intends to qualify each year as a Regulated Investment Company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a RIC, the Fund is not expected to be subject to U.S. federal income tax to the extent that it distributes its investment company taxable income and net capital gains. To qualify for the special tax treatment available to a RIC, the Fund must comply with certain investment, distribution, and diversification requirements. Under certain circumstances, the Fund may be forced to sell certain assets when it is not advantageous in order to meet these requirements, which may reduce the Fund’s overall return. If the Fund fails to meet any of these requirements, subject to the opportunity to cure such failures under applicable provisions of the Code, the Fund’s income would be subject to a double level of U.S. federal income tax. The Fund’s income, including its net capital gain, would first be subject to U.S. federal income tax at regular corporate rates, even if such income were distributed to shareholders and, second, all distributions by the Fund from earnings and profits, including distributions of net capital gain (if any), would be taxable to shareholders as dividends.
Global Economic Risk.
National and regional economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and assets prices around the world, which could negatively impact the value of the Fund’s investments. Major economic or political disruptions, particularly in large economies like China’s, may have global negative economic and market repercussions. Additionally, instability in various countries, such as Afghanistan and Syria, war and natural and environmental disasters, and the spread of infectious illnesses or other public health emergencies, terrorist attacks
in
the United States and around the world, growing social and political discord in the United States, the European debt crisis, the response of the international community—through economic sanctions and otherwise—to international events, further downgrade of U.S. government securities, changes in the U.S. president or political shifts in Congress and other similar events may adversely affect the global economy and the markets and issuers in which the Fund invests. Recent examples of such events include Hamas’ attack on Israel in October 2023 and the ensuing conflict, the outbreak of a novel coronavirus known as
COVID-19
that was first detected in China in December 2019 and heightened concerns regarding North Korea’s nuclear weapons and long-range ballistic missile programs. In addition, Russia’s invasion of Ukraine in February 2022 has resulted in sanctions imposed by several nations, such as the United States, United Kingdom, European Union and Canada. The current sanctions and potential further sanctions may negatively impact certain sectors of Russia’s economy, but also may negatively impact the value of the Fund’s investments that do not have direct exposure to Russia. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a
258

significant impact on the global economy. These events could also impair the information technology and other operational systems upon which the Fund’s service providers, including the Fund’s
sub-adviser,
rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the Fund.
The Fund does not know and cannot predict how long the securities markets may be affected by these events, and the future impact of these and similar events on the global economy and securities markets is uncertain. The Fund may be adversely affected by abrogation of international agreements and national laws which have created the market instruments in which the Fund may invest, failure of the designated national and international authorities to enforce compliance with the same laws and agreements, failure of local, national and international organizations to carry out the duties prescribed to them under the relevant agreements, revisions of these laws and agreements which dilute their effectiveness or conflicting interpretation of provisions of the same laws and agreements.
Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments.
Investment and Market Risk.
An investment in common shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Common shares frequently trade at a discount to their NAV. An investment in common shares represents an indirect investment in the securities owned by the Fund. Common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.
Legislation and Regulatory Risk.
At any time after the date of this report, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund, securities held by the Fund or the issuers of such securities. Fund shareholders may incur increased costs resulting from such legislation or additional regulation. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objectives.
Leverage Risk.
The use of leverage creates special risks for common shareholders, including potential interest rate risks and the likelihood of greater volatility of NAV and market price of, and distributions on, the common shares. The use of leverage in a declining market will likely cause a greater decline in the Fund’s NAV, which may result at a greater decline of the common share price, than if the Fund were not to have used leverage.
The Fund will pay (and common shareholders will bear) any costs and expenses relating to the Fund’s use of leverage, which will result in a reduction in the Fund’s NAV. The investment adviser may, based on its assessment of market conditions, composition of the Fund’s holdings, increase or decrease the amount of leverage. Such changes may impact the Fund’s distributions and the price of the common shares in the secondary market. There is no assurance that the Fund’s use of leverage will be successful.
The Fund may seek to refinance its leverage over time, in the ordinary course, as current forms of leverage mature or it is otherwise desirable to refinance; however, the form that such leverage will take cannot be predicted at this time. If the Fund is unable to replace existing leverage on comparable terms, its costs of leverage will increase. Accordingly, there is no assurance that the use of leverage may result in a higher yield or return to common shareholders.
The amount of fees paid to the investment adviser and the
sub-advisor
for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets - this may create an incentive for the investment adviser and the
sub-advisor
to leverage the Fund or increase the Fund’s leverage.
Limited Term and Tender Offer Risks.
Because the assets of the Fund will be liquidated in connection with its termination or to pay for Common Shares tendered in an Eligible Tender Offer, the Fund may be required to sell portfolio securities when it otherwise would not, including at times when market conditions are not favorable, or at a time when a particular security is in default or bankruptcy, or otherwise in severe distress, which may cause the Fund to lose money.
The Fund may be required to dispose of portfolio investments in connection with any reduction in its outstanding leverage necessary in order to maintain its desired leverage ratios following an Eligible Tender Offer. It is likely that during the pendency of an Eligible Tender Offer, and possibly for a time thereafter, the Fund will hold a greater than normal percentage of its total assets in money market mutual funds, cash, cash equivalents, securities issued or guaranteed by the U.S. government or its instrumentalities or agencies, high quality, short-term money market instruments, short-term debt securities, certificates of deposit, bankers’ acceptances and other bank obligations, commercial paper or other liquid debt securities, which may adversely affect the Fund’s investment performance. If the tax basis for the portfolio investments sold is less than the sale proceeds, the Fund will recognize capital gains, which it will be required to distribute to Common Shareholders. In addition, the Fund’s purchase of tendered Common Shares pursuant to an Eligible Tender Offer will have tax consequences for tendering Common Shareholders and may have tax consequences for
non-tendering
Common Shareholders. All Common Shareholders remaining after an Eligible Tender Offer will be subject to proportionately higher expenses due to the reduction in the Fund’s total assets resulting from payment for the tendered Common Shares. Such reduction in the Fund’s total assets also may result in less investment flexibility, reduced diversification and greater volatility for the Fund, and may have an adverse effect on the Fund’s investment performance.
If the Fund conducts an Eligible Tender Offer, there can be no assurance that the number of tendered Common Shares would not result in the Fund’s net assets totaling less than the Termination Threshold, in which case the Eligible Tender Offer will be terminated, no Common Shares will be repurchased pursuant to the Eligible Tender Offer and the Fund will terminate on the Termination Date. The investment adviser may have a conflict of interest in recommending to the Board of Trustees that the Fund have a continued existence without limitation of time. The Fund is not required to conduct additional tender offers following an Eligible Tender Offer and conversion to a continued existence without limitation of time. Therefore, remaining Common Shareholders may not have another opportunity to participate in a tender offer.
259

Shareholder Update
(Unaudited) (continued)
A Fund portfolio holding default may significantly reduce net investment income and, therefore, Common Share dividends; and may prevent or inhibit the Fund from fully being able to liquidate its portfolio at or prior to the Termination Date.
Market Discount from Net Asset Value.
Shares of
closed
-end
investment companies like the Fund frequently trade at prices lower than their NAV. This characteristic is a risk separate and distinct from the risk that the Fund’s NAV could decrease as a result of investment activities. Whether investors will realize gains or losses upon the sale of the common shares will depend not upon the Fund’s NAV but entirely upon whether the market price of the common shares at the time of sale is above or below the investor’s purchase price for the common shares. Furthermore, management may have difficulty meeting the Fund’s investment objectives and managing its portfolio when the underlying securities are redeemed or sold during periods of market turmoil and as investors’ perceptions regarding
closed-end
funds or their underlying investments change. Because the market price of the common shares will be determined by factors such as relative supply of and demand for the common shares in the market, general market and economic circumstances, and other factors beyond the control of the Fund, the Fund cannot predict whether the common shares will trade at, below or above NAV. The common shares are designed primarily for long-term investors, and you should not view the Fund as a vehicle for short-term trading purposes.
Recent Market Conditions.
Periods of unusually high financial market volatility and restrictive credit conditions, at times limited to a particular sector or geographic area, have occurred in the past and may be expected to recur in the future. Some countries, including the United States, have adopted or have signaled protectionist trade measures, relaxation of the financial industry regulations that followed the financial crisis, and/ or reductions to corporate taxes. The scope of these policy changes is still developing, but the equity and debt markets may react strongly to expectations of change, which could increase volatility, particularly if a resulting policy runs counter to the market’s expectations. The outcome of such changes cannot be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health risks, may add to instability in the world economy and markets generally. As a result of increasingly interconnected global economies and financial markets, the value and liquidity of the Fund’s investments may be negatively affected by events impacting a country or region, regardless of whether the Fund invests in issuers located in or with significant exposure to such country or region.
Ukraine has experienced ongoing military conflict, most recently in February 2022 when Russia invaded Ukraine; this conflict may expand and military attacks could occur elsewhere in Europe. Europe has also been struggling with mass migration from the Middle East and Africa. The ultimate effects of these events and other socio-political or geographical issues are not known but could profoundly affect global economies and markets. Additionally, in October 2023 armed conflict broke out between Israel and the militant group Hamas after Hamas infiltrated Israel’s southern border from the Gaza Strip. Israel has since declared war against Hamas and it’s possible that this conflict could escalate into a greater regional conflict. The ultimate effects of these events and other socio-political or geographical issues are not known but could profoundly affect global economies and markets.
The ongoing trade war between China and the United States, including the imposition of tariffs by each country on the other country’s products, has created a tense political environment. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Fund’s performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.
Recently the U.S. Federal Reserve (the “Fed”) has sharply raised interest rates and has signaled an intention to continue to do so or maintain higher interest rates until current inflation levels
re-align
with the Fed’s long-term inflation target. Changing interest rate environments impact the various sectors of the economy in different ways. For example, in March 2023, the Federal Deposit Insurance Corporation (““FDIC””) was appointed receiver for each of Silicon Valley Bank and Signature Bank, the second- and third-largest bank failures in U.S. history, which failures may be attributable, in part, to rising interest rates. Bank failures may have a destabilizing impact on the broader banking industry or markets generally.
Reverse Repurchase Agreement Risk.
A reverse repurchase agreement, in economic essence, constitutes a securitized borrowing by the Fund from
the
security purchaser. The Fund may enter into reverse repurchase agreements for the purpose of creating a leveraged investment exposure and, as such, their usage involves essentially the same risks associated with a leveraging strategy generally since the proceeds from these agreements may be invested in additional portfolio securities. Reverse repurchase agreements tend to be short-term in tenor, and there can be no assurances that the purchaser (lender) will commit to extend or “roll” a given agreement upon its agreed-upon repurchase date or an alternative purchaser can be identified on similar terms. Reverse repurchase agreements also involve the risk that the purchaser fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

EFFECTS OF LEVERAGE
The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effects of leverage through the use of senior securities, as that term is defined under Section 18 of the 1940 Act, as well as certain other forms of leverage, such as reverse repurchase agreements and investments in inverse floating rate securities, on common share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in a Fund’s portfolio) of
-10%,
-5%,
0%, 5% and 10%. The table below reflects each Fund’s (i) continued use of leverage as of October 31, 2023 as a percentage of Managed Assets (including assets attributable to such leverage), (ii) the estimated annual effective interest expense rate payable by the Funds on such instruments (based on actual leverage costs incurred during the fiscal year ended October 31, 2023) as set forth in the table, and (iii) the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs of leverage based on such estimated annual effective interest expense rate. The information below does not reflect any Fund’s use of certain derivative instruments.
The numbers are merely estimates, used for illustration. The costs of leverage may vary frequently and may be significantly higher or lower than the estimated rate. The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Funds. Your actual returns may be greater or less than those appearing below.

|  | Nuveen AMT-Free Municipal Credit Income Fund (NVG) |  | Nuveen Municipal Credit Income Fund (NZF) |  | Nuveen Municipal High Income Opportunity Fund (NMZ) |  | Nuveen Municipal Credit Opportunities Fund (NMCO) |  | Nuveen Dynamic Municipal Opportunities Fund (NDMO)
Estimated Leverage as a Percentage of Managed Assets (Including Assets Attributable to Leverage) |  | 43.94% |  | 42.40% |  | 42.51% |  | 44.94% |  | 29.20%
Estimated Annual Effective Leverage Expense Rate Payable by Fund on Leverage |  | 4.01% |  | 4.13% |  | 3.91% |  | 4.19% |  | 4.09%
Annual Return Fund Portfolio Must Experience (net of expenses) to Cover Estimated Annual Effective Interest Expense Rate on Leverage |  | 1.76% |  | 1.75% |  | 1.66% |  | 1.88% |  | 1.19%
Common Share Total Return for (10.00)% Assumed Portfolio Total Return |  | (20.98)% |  | (20.40)% |  | (20.29)% |  | (21.58)% |  | (15.81)%
Common Share Total Return for (5.00)% Assumed Portfolio Total Return |  | (12.06)% |  | (11.72)% |  | (11.59)% |  | (12.50)% |  | (8.75)%
Common Share Total Return for 0.00% Assumed Portfolio Total Return |  | (3.14)% |  | (3.04)% |  | (2.89)% |  | (3.42)% |  | (1.69)%
Common Share Total Return for 5.00% Assumed Portfolio Total Return |  | 5.77% |  | 5.64% |  | 5.80% |  | 5.66% |  | 5.38%
Common Share Total Return for 10.00% Assumed Portfolio Total Return |  | 14.69% |  | 14.32% |  | 14.50% |  | 14.74% |  | 12.44%

Common Share total return is composed of two elements — the distributions paid by the Fund to holders of common shares (the amount of which is largely determined by the net investment income of the Fund after paying dividend payments on any preferred shares issued by the Fund and expenses on any forms of leverage outstanding) and gains or losses on the value of the securities and other instruments the Fund owns. As required by SEC rules, the table assumes that the Funds are more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, the Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments. This table reflects hypothetical performance of the Fund’s portfolio and not the actual performance of the Fund’s common shares, the value of which is determined by market forces and other factors. Should the Fund elect to add additional leverage to its portfolio, any benefits of such additional leverage cannot be fully achieved until the proceeds resulting from the use of such leverage have been received by the Fund and invested in accordance with the Fund’s investment objectives and policies. As noted above, the Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors.

(Unaudited) (continued)
DIVIDEND REINVESTMENT PLAN
Nuveen
Closed-End
Funds Automatic Reinvestment Plan
Your 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 NAV at the time of valuation, the Fund will issue new shares at the greater of the NAV or 95% of the then-current market price. If the shares are trading at less than NAV, shares for your account will be purchased on the open market. If Computershare Trust Company, N.A. (the “Plan Agent”) begins purchasing Fund shares on the open market while shares are trading below NAV, but the Fund’s shares subsequently trade at or above their NAV 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’ NAV 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 Dividend Reinvestment Plan (the “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.

CHANGES OCCURRING DURING THE FISCAL YEAR
The following information in this annual report is a summary of certain changes during the most recent fiscal year. This information may not reflect all of the changes that have occurred since you purchased shares of a Fund.
During the most recent fiscal year, there have been no changes required to be reported in connection with: (i) the Funds’ investment objectives and principal investment policies that have not been approved by shareholders, (ii) the principal risks of the Fund, (iii) the portfolio managers of the Funds; (iv) a Fund’s charter or
by-laws
that would delay or prevent a change of control of the Fund that have not been approved by shareholders except as follows:
Developments Regarding the Funds’ Control Share
By-Law
On October 5, 2020, the Nuveen
AMT-Free
Municipal Credit Income Fund, Nuveen Municipal Credit Income Fund, Nuveen Municipal High Income Opportunity Fund, Nuveen Municipal Credit Opportunities Fund and the Nuveen Dynamic Opportunities Fund (each a “Fund” and collectively the “Funds”) and certain other
closed-end
funds in the Nuveen fund complex amended their
by-laws.
Among other things, the amended
by-laws
included provisions pursuant to which, in summary, a shareholder who obtains beneficial ownership of common shares in a Control Share Acquisition (as defined in the
by-laws)
shall have the same voting rights as other common shareholders only to the extent authorized by the other disinterested shareholders (the “Control Share
By-Law”).
On January 14, 2021, a shareholder of certain Nuveen
closed-end
funds filed a civil complaint in the U.S. District Court for the Southern District of New York (the “District Court”) against certain Nuveen funds and their trustees, seeking a declaration that such funds’ Control Share
By-Laws
violate the 1940 Act, rescission of such fund’s Control Share
By-Laws
and a permanent injunction against such funds applying the Control Share
By-Laws.
On February 18, 2022, the District Court granted judgment in favor of the plaintiff’s claim for rescission of such funds’ Control Share
By-Laws
and the plaintiff’s declaratory judgment claim, and declared that such funds’ Control Share
By-Laws
violate Section 18(i) of the 1940 Act. Following review of the judgment of the District Court, on February 22, 2022, the Board amended the Funds’ bylaws to provide that the Funds’ Control Share
By-Law
shall be of no force and effect for so long as the judgment of the District Court is effective and that if the judgment of the District Court is reversed, overturned, vacated, stayed, or otherwise nullified, the Fund’s Control Share
By-Law
will be automatically reinstated and apply to any beneficial owner of common shares acquired in a Control Share Acquisition, regardless of whether such Control Share Acquisition occurs before or after such reinstatement, for the duration of the stay or upon issuance of the mandate reversing, overturning, vacating or otherwise nullifying the judgment of the District Court. On February 25, 2022, the Board and the Funds appealed the District Court’s decision to the U.S. Court of Appeals for the Second Circuit. On November 30, 2023, the U.S. Court of Appeals for the Second Circuit upheld the opinion of the District Court.
Principal Risks
The following risk factor was added as a principal risk to the Funds:
Fund Tax Risk.
The Fund has elected to be treated and intends to qualify each year as a Regulated Investment Company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a RIC, the Fund is not expected to be subject to U.S. federal income tax to the extent that it distributes its investment company taxable income and net capital gains. To qualify for the special tax treatment available to a RIC, the Fund must comply with certain investment, distribution, and diversification requirements. Under certain circumstances, the Fund may be forced to sell certain assets when it is not advantageous in order to meet these requirements, which may reduce the Fund’s overall return. If the Fund fails to meet any of these requirements, subject to the opportunity to cure such failures under applicable provisions of the Code, the Fund’s income would be subject to a double level of U.S. federal income tax. The Fund’s income, including its net capital gain, would first be subject to U.S. federal income tax at regular corporate rates, even if such income were distributed to shareholders and, second, all distributions by the Fund from earnings and profits, including distributions of net capital gain (if any), would be taxable to shareholders as dividends.
The following principal risks were consolidated into a single risk factor entitled, “Economic Sector Risk,” and are therefore no longer included as stand-alone principal risks:
Sector and Industry Risk.
Subject to the concentration limits of the Fund’s investment policies and guidelines, a Fund may invest a significant portion of its net assets in certain sectors of the municipal securities market, such as hospitals and other health care facilities, charter schools and other private educational facilities, special taxing districts and
start-up
utility districts, and private activity bonds including industrial development bonds on behalf of transportation companies such as airline companies, whose credit quality and performance may be more susceptible to economic, business, political, regulatory and other developments than other sectors of municipal issuers. If the Fund invests a significant portion of its net assets in the sectors noted above, the Fund’s performance may be subject to additional risk and variability.
Sector Focus Risk.
At times, the Fund may focus its investments (i.e., overweight its investments relative to the overall municipal securities market) in one or more particular sectors, which may subject the Fund to additional risk and variability. Securities issued in the same sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that sector than funds that invest more broadly. As the percentage of the Fund’s Managed Assets invested in a particular sector increases, so does the potential for fluctuation in the NAV of the Fund’s common shares.
The following principal risk was consolidated into a single risk factor entitled, “Distressed or Defaulted Securities Risk,” and is therefore no longer included as a stand-alone principal risk:
263

Shareholder Update
(Unaudited) (continued)
Distressed Securities Risk.
The Fund may invest in
low-rated
securities or securities unrated but judged by the
sub-adviser
to be of comparable quality. Some or many of these
low-rated
securities, although not in default, may be “distressed,” meaning that the issuer is experiencing financial difficulties or distress at the time of acquisition. Such securities would present a substantial risk of future default which may cause the Fund to incur losses, including additional expenses, to the extent it is required to seek recovery upon a default in the payment of principal or interest on those securities. In any reorganization or liquidation proceeding relating to a portfolio security, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities may be subject to restrictions on resale.
The following principal risk was removed as a principal risk of the Funds:
London Inter-Offered Bank Rate (“LIBOR”) Replacement Risk.
LIBOR is an index
r
ate that historically has been widely used in lending transactions and remains a common reference rate for setting the floating interest rate on private loans. The use of the LIBOR will begin to be phased out in the near future, which may adversely affect the Fund’s investments whose value is tied to LIBOR. While the Secured Overnight Financing Rate (“SOFR”) has been recommended as the replacement rate for LIBOR, and some product markets have adopted the use of SOFR, LIBOR may still be used as a reference rate until such time that private markets have fully transitioned to using SOFR or other alternative reference rates recommended by applicable market regulators. The transition process away from LIBOR may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR. The potential effect of a discontinuation of LIBOR on the Fund’s investments will vary depending on, among other things: (1) existing fallback provisions that provide a replacement reference rate if LIBOR is no longer available; (2) termination provisions in individual contracts; and (3) how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments held by the Fund. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR until it is clearer how the Fund’s products and instruments will be impacted by this transition.
Investment Policies
Effective June 22, 2023, the Board of Trustees (the “Board”) of Nuveen
AMT-Free
Municipal Credit Income Fund (NVG), Nuveen Municipal Credit Income Fund (NZF), and Nuveen Municipal High Income Opportunity Fund (NMZ) approved a change in each such Fund’s maturity policy. The maturity policy for each of NVG, NZF and NMZ effective as of June 22, 2023 is presented below:
“Under normal circumstances, the Fund will generally maintain an investment portfolio with an overall weighted average maturity of greater than 10 years.”
Portfolio Managers
Nuveen Municipal Credit Opportunities Fund (NMCO),
Nuveen Dynamic Municipal Credit Opportunities Fund (NDMO) and
Nuveen Municipal High Income Opportunity Fund (NMZ)
Effective June 1, 2023, John V. Miller, portfolio manager for NMCO, NDMO and NMZ, retired for Nuveen. Daniel J. Close, CFA, Managing Director, and Stephen J. Candido, CFA, Managing Director, have each been named a portfolio manager for each of NMCO, NDMO and NMZ. Timothy Ryan will continue to serve as portfolio manager of NDMO. Steven M. Hlavin will continue to serve as portfolio manager of NMCO. The
day-to-day
operation of each Fund and the execution of its specific investment strategies is the primary responsibility of each of the Fund’s portfolio managers. The biographies of Daniel J. Close and Stephen J. Candido are presented below:
Daniel J. Close, CFA, is Managing Director and Portfolio Manager at Nuveen Asset Management, LLC (“Nuveen Asset Management”).

SUMMARY OF FUND EXPENSES
The purpose of the tables and the examples below are to help you understand all fees and expenses that you, as a common shareholder, would bear directly or indirectly. The tables show the expenses of each Fund as a percentage of the average net assets applicable to Common Shares and not as a percentage of total assets or managed assets.

Shareholder Transaction Expenses |  | Nuveen AMT-Free Municipal Credit Income Fund (NVG) |  | Nuveen Municipal High Income Opportunity Fund (NMZ) |  | Nuveen Municipal Credit Opportunities Fund (NMCO) |  | Nuveen Dynamic Municipal Opportunities Fund (NDMO)
Maximum Sales Charge (as a percentage of offering price |  | 1.00% (1) |  | 4.00% (2) |  | 4.00% (2) |  | 1.00% (1)
Dividend Reinvestment Plan Fees (3) |  | $2.50 |  | $2.50 |  | $2.50 |  | $2.50

(1) | A maximum sales charge of 1.00% applies only to offerings made at-the-market. There is no sales charge for offerings pursuant to an underwritten transaction or a private transaction.

(2) | A maximum sales charge of 4.00% applies only to offerings pursuant to a syndicated underwriting. The maximum sales charge for offerings made at-the-market is 1.00%. There is no sales charge for offerings pursuant to a private transaction.

(3) | You will be charged a $2.50 service charge and pay brokerage charges if you direct Computershare Inc. and Computershare Trust Company, N.A., as agent for the common shareholders, to sell your Common Shares held in a dividend reinvestment account.

|  | As a Percentage of Net Assets Attributable to Common Shares (1)
Annual Expenses |  | Nuveen AMT-Free Municipal Credit Income Fund (NVG) |  | Nuveen Municipal High Income Opportunity Fund (NMZ) |  | Nuveen Municipal Credit Opportunities Fund (NMCO) |  | Nuveen Dynamic Municipal Opportunities Fund (NDMO)
Management Fees |  | 1.02% |  | 1.05% |  | 1.53% |  | 1.15%
Interest and Other Related Expenses (2) |  | 2.78% |  | 2.59% |  | 3.12% |  | 1.54%
Other Expenses (3) |  | 0.05% |  | 0.11% |  | 0.13% |  | 0.07%
Total Annual Expenses |  | 3.85% |  | 3.75% |  | 4.78% |  | 2.76%

(1) | Stated as percentages of average net assets attributable to Common Shares for the fiscal year ended October 31, 2023.

(2) | Interest and Other Related Expenses reflect actual expenses and fees for leverage incurred by a Fund for the fiscal year ended October 31, 2023. The types of leverage used by each Fund during the fiscal year ended October 31, 2023 are described in the Fund Leverage and the Notes to Financial Statements (Note 4 – Portfolio Securities, Note 5 – Derivative Investments, Note 6 – Fund Shares, Note 10 – Borrowings Arrangements and Reverse Repurchase Agreements) sections of this annual report. Actual Interest and Other Related Expenses incurred in the future may be higher or lower. If short-term market interest rates rise in the future, and if a Fund continues to maintain leverage, the cost of which is tied to short-term interest rates, a Fund’s interest expenses on its short-term borrowings can be expected to rise in tandem. A Fund’s use of leverage will increase the amount of management fees paid to the Fund’s adviser and sub-advisor(s).

(3) | Other Expenses are based on estimated amounts for the current fiscal year. Expenses attributable to the Fund’s investments, if any, in other investment companies are currently estimated not to exceed 0.01%.

Shares of
closed-end
investment companies, including those of the Funds, may frequently trade at prices lower than NAV, the Funds’ Board of Trustees (Board) has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from NAV in respect of Common Shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at NAV, or the conversion of the Fund to an
open-end
investment company. The Funds cannot assure you that their Board will decide to take any of these actions, or that share repurchases or tender offers will actually reduce market discount.
SENIOR SECURITIES
The following table sets forth information regarding each Fund’s outstanding senior securities as of the end of each of the Fund’s last ten fiscal periods, as applicable. Each Fund’s senior securities during this time period are comprised of borrowings that constitute “senior securities” as defined in the Investment Company Act of 1940, as amended (1940 Act).

Glossary of Terms Used in this Report
(Unaudited)
Average Annual Total Return:
This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or offer price and reinvested dividends and capital gains distributions, if any) over the time period being considered.
Duration:
Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond fund’s value to changes when market interest rates change. Generally, the longer a bond’s or fund’s duration, the more the price of the bond or fund will change as interest rates change.
Effective Leverage:
Effective leverage is a fund’s effective economic leverage, and includes both regulatory leverage (see leverage) and the leverage effects of certain derivative investments in the fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.
Gross Domestic Product (GDP):
The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.
Industrial Development Revenue Bond (IDR):
A unique type of revenue bond issued by a state or local government agency on behalf of a private sector company and intended to build or acquire factories or other heavy equipment and tools.
Inverse Floating Rate Securities:
Inverse floating rate securities are the residual interest in a tender option bond (TOB) trust, sometimes referred to as “inverse floaters”, are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust. This trust, in turn, (a) issues floating rate certificates typically paying short-term
tax-exempt
interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.
Leverage:
Leverage is created whenever a fund has investment exposure (both reward and/or risk) equivalent to more than 100% of the investment capital.
Net Asset Value (NAV) Per Share:
A fund’s Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund’s Net Assets divided by its number of shares outstanding.
Pre-Refunded
Bond/Pre-Refunding:
Pre-Refunded
Bond/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.
Regulatory Leverage:
Regulatory leverage consists of preferred shares issued by or borrowings of a fund. Both of these are part of a fund’s capital structure. Regulatory leverage is subject to asset coverage limits set in the Investment Company Act of 1940.
Tax Obligation/General Bonds:
Bonds backed by the general revenues of an issuer, including taxes, where the issuer has the ability to increase taxes by an unlimited amount to pay the bonds back.
Tax Obligation/Limited Bonds:
Bonds backed by the general revenues of an issuer, including taxes, where the issuer doesn’t have the ability to increase taxes by an unlimited amount to pay the bonds back.
Total Investment Exposure:
Total investment exposure is a fund’s assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a fund’s use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.
275

Glossary of Terms Users in the Report
(Unaudited) (continued)
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.

Annual Investment Management
Agreement Approval Process
(Unaudited)
At a meeting held on May
23-25,
2023 (the “May Meeting”), the Boards of Trustees (collectively, the “Board” and each Trustee, a “Board Member”) of the Funds, which are 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, for their respective Fund, the renewal of the management agreement (each, an “Investment Management Agreement”) with Nuveen Fund Advisors, LLC (the “Adviser”) pursuant to which the Adviser serves as investment adviser to such Fund and the
sub-advisory
agreement (each, a
“Sub-Advisory
Agreement”) with Nuveen Asset Management, LLC (the
“Sub-Adviser”)
pursuant to which the
Sub-Adviser
serves as the
sub-adviser
to such Fund for an additional
one-year
term. As the Board is comprised of all Independent Board Members, the references to the Board and the Independent Board Members are interchangeable.
Following up to an initial
two-year
period, the Board considers the renewal of each Investment Management Agreement and
Sub-Advisory
Agreement on behalf of the applicable Fund on an annual basis. The Investment Management Agreements and
Sub-Advisory
Agreements are collectively referred to as the “Advisory Agreements,” and the Adviser and the
Sub-Adviser
are collectively, the “Fund Advisers” and each, a “Fund Adviser.”
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 the applicable
sub-advisers
in their annual review of the advisory agreements. Throughout the year, the Board and its committees meet regularly and, at these meetings, receive regular and/or special reports that cover an extensive array of topics and information that are relevant to the Board’s annual consideration of the renewal of the advisory agreements for the Nuveen funds. Such information may address, among other things, fund performance and risk information; the Adviser’s strategic plans; product initiatives for various funds; the review of the funds and investment teams; compliance, regulatory and risk management matters; the trading practices of the various
sub-advisers
to the Nuveen funds; management of distributions; valuation of securities; fund expenses; securities lending; liquidity management; overall market and regulatory developments; and with respect to
closed-end
funds, capital management initiatives, institutional ownership, management of leverage financing and the secondary market trading of the
closed-end
funds and any actions to address discounts. The Board also seeks to meet periodically with the Nuveen funds’
sub-advisers
and/or portfolio teams, when feasible. The presentations, discussions, and meetings throughout the year also provide a means for the Board to evaluate the level, breadth and quality of services provided by the Adviser and how such services have changed over time in light of new or modified regulatory requirements, changes to market conditions or other factors.
In connection with its annual consideration of the advisory agreements for the Nuveen funds, the Board, through its independent legal counsel, requested and received extensive materials and information prepared specifically for its review of such advisory agreements 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 product actions advanced in 2022 for the benefit of particular Nuveen funds and/or the Nuveen fund complex; a review of each
sub-adviser
to the Nuveen funds and/or the applicable investment team; an analysis of fund performance with a focus on any Nuveen funds considered performance outliers; an analysis of the fees and expense ratios of the Nuveen funds with a focus on any Nuveen funds considered expense outliers; a review of management fee schedules; a description of portfolio manager compensation; an overview of the secondary market trading of shares of the Nuveen
closed-end
funds (including, among other things, an analysis of secondary market performance and commentary regarding the leverage management, share repurchase and shelf offering programs of Nuveen
closed-end
funds); 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. The information prepared specifically for the annual review supplemented the information provided to the Board and its committees and the evaluations of the Nuveen funds by the Board and its committees during the year. The Board’s review of the advisory agreements for the Nuveen funds is based on all the information provided to the Board and its committees throughout the year as well as the information prepared specifically with respect to the annual review of such advisory agreements. The performance, fee and expense data and other information provided by a Fund Adviser, Broadridge or other service providers were not independently verified by the Independent Board Members.
As part of its review, the Board met on April
11-12,
2023 (the “April Meeting”) 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 and/or its investment teams. At the April Meeting, the Board Members asked questions and requested additional information that was provided for the May Meeting.
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, including guidance from court cases evaluating advisory fees.
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 to the Board and its committees throughout the year as well as the materials prepared specifically in connection with the renewal process. The contractual arrangements are a result of multiple years of review, negotiation and information provided in connection with the Board’s annual review of the Nuveen funds’ advisory arrangements and oversight of the Nuveen funds. Each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the approval process and may place different emphasis on the relevant information year to year in light of, among other things, changing market and economic conditions. A summary of the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements is set forth below.
277

Annual Investment Management Agreement Approval Process
(Unaudited) (continued)
A. Nature, Extent and Quality of Services
In evaluating the renewal of the Advisory Agreements, the Independent Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to the respective Fund with particular focus on the services and enhancements or changes to such services provided during the last year. The Independent Board Members considered the Investment Management Agreements and the
Sub-Advisory
Agreements separately in the course of their review. With this approach, they considered the respective roles of the Adviser and the
Sub-Adviser
in providing services to the Funds.
The Board recognized that the Adviser provides a wide array of management, oversight and administrative services to manage and operate the Nuveen funds and that the scope and complexity of these services, along with the undertakings required of the Adviser in connection with providing these services, have expanded over time as a result of, among other things, regulatory, market and other developments. The Board noted the Adviser’s dedication of resources, time, personnel and capital and commitment to continuing to develop improvements and innovations that seek to enhance the Nuveen fund complex and meet the needs of the Nuveen funds in an increasingly complex regulatory environment. The Board received and reviewed information regarding, among other things, the Adviser’s investment oversight responsibilities, regulatory and compliance services, administrative duties and other services.
The Board considered the breadth and the quality of the services the Adviser and its various teams provide in overseeing the investment management of the Nuveen funds, including, among other things, overseeing and reviewing the services provided by the various
sub-advisers
to the Nuveen funds and their investment teams; evaluating fund performance and market conditions; overseeing operational and investment risks; evaluating investment strategies and recommending any changes thereto; managing liquidity; managing the daily valuation of portfolio securities; overseeing trade execution and securities lending; and setting and managing distributions consistent with the respective fund’s product design. With respect to
closed-end
funds, such services also include managing leverage; monitoring asset coverage levels for leveraged funds and compliance with rating agency criteria; providing capital management and secondary market services (such as implementing common share shelf offerings, capital return programs and common share repurchases); and maintaining a
closed-end
fund investor relations program. The Board also reviewed the structure of investment personnel compensation of each Fund Adviser and considered whether the structure provides appropriate incentives to attract and maintain qualified personnel and to act in the best interests of the respective Nuveen fund.
Given the Nuveen funds operate in a highly regulated industry, the Board further considered the extensive compliance, regulatory and administrative services the Adviser and its various teams provide to manage and operate the Nuveen funds. The Board recognized such services included, but were not limited to, managing compliance policies; monitoring compliance with applicable policies, laws and regulations; devising internal compliance programs in seeking to enhance compliance with regulatory requirements and creating a framework to review and assess compliance programs; overseeing
sub-adviser
compliance testing; preparing compliance training materials; and responding to regulatory requests. The Board reviewed highlights of the various initiatives Nuveen compliance had taken in 2022 including, among other things, additional due diligence of service providers as their operating environments evolve post-Covid to more hybrid
in-person
working arrangements; investments in supporting and expanding international trading capabilities; continuing efforts to enhance policies and controls to address compliance risks including those related to environmental, social and governance (“ESG”) matters and new regulatory developments or guidance; and establishing and maintaining compliance policies and comprehensive compliance training programs. The Board also considered information regarding the Adviser’s business continuity, disaster recovery and information security programs and the periodic testing and review of such programs.
In addition to the above functions, the Board considered the quality and extent of other
non-advisory
services the Adviser provides including, among other things, various fund administration services (such as preparing, overseeing or assisting with the preparation of tax and regulatory filings); product management services (such as evaluating and enhancing products and strategies); legal support services; shareholder services and transfer agency function oversight services; and board support and reporting services. With respect to board support services, the Board reviewed a summary of the annual, quarterly, and special reports the Adviser and/or its affiliates provided to the Board throughout 2022.
The Board further acknowledged various initiatives the Adviser had undertaken or continued in 2022 in seeking to improve the effectiveness of its organization, the Nuveen funds product
line-up
as well as particular Nuveen fund(s) through, among other things, rationalizing the product line and gaining efficiencies through mergers, repositionings and liquidations; launching new funds; reviewing and updating investment policies and benchmarks; reopening certain funds previously closed to new investors; adding or modifying the share classes offered by certain funds; implementing fee waivers and expense cap changes for certain funds and evaluating and adjusting portfolio management teams as appropriate for various funds; and developing policy positions on a broad range of regulatory proposals that may impact the funds and communicating with lawmakers and other regulatory authorities to help ensure these positions are represented.
Aside from the services provided, the Board recognized the financial resources of the Adviser and its affiliates and their willingness to make investments in the technology, personnel and infrastructure to support the Nuveen funds, including maintaining a seed capital budget to support new or existing funds and/or facilitate changes for a respective fund. The Board noted the benefits to shareholders of investing in a fund that is a part of a large fund complex with a variety of investment disciplines, capabilities, expertise and resources available to navigate and support the Nuveen funds including during stressed times. The Board recognized the overall reputation and capabilities of the Adviser and its affiliates, the Adviser’s continuing commitment to provide high quality services, its willingness to implement operational or organizational changes in seeking, among other things, to enhance efficiencies and services to the Nuveen funds and its responsiveness to the Board’s questions and/or concerns raised throughout the year and during the annual review of advisory agreements. The Board also considered the significant risks borne by the Adviser and its affiliates in connection with their services to the Nuveen funds, including entrepreneurial risks in sponsoring new funds and ongoing risks with managing the funds such as investment, operational, reputational, regulatory, compliance and litigation risks.
The Board further considered the division of responsibilities between the Adviser and the
Sub-Adviser
and recognized that the
Sub-Adviser
and its investment personnel generally are responsible for the management of each Fund’s portfolio under the oversight of the Adviser and the Board. The Board considered an analysis of the
Sub-Adviser
provided by the Adviser which included, among other things, the assets under management of the applicable investment team and changes thereto, a summary of the applicable investment team and changes to such team, the investment process
278

and philosophy of the applicable investment team, the performance of the Nuveen funds
sub-advised
by the
Sub-Adviser
over various periods of time and a summary of any significant policy and/or other changes to the Nuveen funds
sub-advised
by the
Sub-Adviser.
The Board further considered at the May Meeting or prior meetings evaluations of the
Sub-Adviser’s
compliance programs and trade execution. The Board noted that the Adviser recommended the renewal of the
Sub-Advisory
Agreements.
Based on its review, the Board determined, in the exercise of its reasonable business judgment, that it was satisfied with the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement.
B. The Investment Performance of the Funds and Fund Advisers
In evaluating the quality of the services provided by the Fund Advisers, the Board also considered a variety of investment performance data of the Nuveen funds prepared specifically for the annual review of the advisory agreements as well as the performance data the Board received throughout the year representing different time periods. In this regard, leading into the May Meeting, the Board reviewed, among other things, Fund performance over the quarter,
one-,
three- and five-year periods ending December 31, 2022 and March 31, 2023 (or for such shorter periods available to the extent a Fund was not in existence during such periods). In addition, the Board reviewed and discussed performance data at its regularly scheduled quarterly meetings during the year. The Board therefore took into account the performance data, presentations and discussions (written and oral) that have been provided for the annual review as well as in prior meetings over time in evaluating fund performance, including the Adviser’s analysis of a fund’s performance with particular focus on performance outliers (both overperformance and underperformance), the factors contributing to performance (including relative to a fund’s benchmark and peers and the impact of market conditions) and any recommendations or steps that had been taken or were proposed to be taken to address significant performance concerns. In this regard, the Board noted, among other things, that certain Nuveen funds had changes in portfolio managers or other significant changes to their investment strategies or policies since March 2020, and, as a result, the Board reviewed certain tracking performance data comparing the performance of such funds before and after such changes.
The Board recognized that performance data reflects performance over a specified period which may differ significantly depending on the ending dates selected, particularly during periods of market volatility. Further, the Board noted that shareholders may evaluate performance based on their own respective holding periods which may differ from the performance periods reviewed by the Board and lead to differing results.
In its evaluation, the Board reviewed Nuveen fund performance results from different perspectives. In general, subject to certain exceptions, the Board reviewed both absolute and relative fund performance during the annual review over the various time periods and evaluated performance results in light of a fund’s investment objective(s), strategies and risks. With respect to the relative performance, 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). In reviewing such comparative performance, the Board was cognizant of the inherent limitations of such data which can make meaningful performance comparisons generally difficult. As an illustration, differences in the composition of the Performance Peer Group, the investment objective(s), strategies and other characteristics of the peers in the Performance Peer Group, the level, type and cost of leverage (if any) of the peers, and the varying sizes of peers all may contribute to differences in the performance results of a Performance Peer Group compared to the applicable Nuveen fund. With respect to relative performance of a Nuveen fund compared to a benchmark index, differences, among other things, in the investment objective(s) and strategies of a fund and the benchmark (particularly an actively managed fund that does not directly follow an index) as well as the costs of operating a fund would necessarily contribute to differences in performance results and limit the value of the comparative performance 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.
The secondary market trading of shares of the Nuveen
closed-end
funds also continues to be a priority for the Board given its importance to shareholders, and therefore the Board and/or its
Closed-end
Fund committee reviews certain performance data reflecting, among other things, the premiums and discounts at which the shares of the Nuveen
closed-end
funds have traded over specified periods throughout the year. In its review, the Board considers, among other things, changes to investment mandates and guidelines, distribution policies, leverage levels and types; share repurchases and similar capital market actions; and effective communications programs to build greater awareness and deepen understanding of
closed-end
funds. As applicable, the Board considered the impact of leverage on a Nuveen fund’s performance. The Board further acknowledged that performance results should include the distribution yields of funds that seek to provide income as part of their investment objective(s) to shareholders. In this regard, the Board considered that the use of leverage by various funds may have detracted from total return performance of such funds over various periods in current market conditions, but the leverage also was accretive in helping to provide income.
The Board also evaluated Nuveen fund performance in light of various relevant factors which may include, among other things, general market conditions, issuer-specific information, asset class information, leverage and fund cash flows. The Board acknowledged that long-term performance could be impacted by even one period of significant outperformance or underperformance and that a single investment theme could disproportionately affect performance. Further, the Board recognized that the market and economic conditions may significantly impact a fund’s performance, particularly over shorter periods, and such performance may be more reflective of such economic or market events and not necessarily reflective of management skill. Although the Board reviews short-, intermediate- and longer-term performance data, the Board recognized that longer periods of performance may reflect full market cycles.
In relation to recent general market conditions, the Board had recognized the general market volatility and underperformance of the market in 2022 in considering Nuveen fund performance. The Board took into account the Adviser’s assessment of a fund’s performance during the recent period of significant market volatility. In their review from year to year, the Board Members consider and may place different emphasis on the relevant information in light of changing circumstances in market and economic conditions. In evaluating performance, the Board focused particular attention on funds with less favorable performance records. However, depending on the facts and circumstances including any differences between the respective fund and its benchmark and/or Performance Peer Group, the Board may be satisfied with a fund’s performance notwithstanding
279

Annual Investment Management Agreement Approval Process
(Unaudited) (continued)
that its performance may be below that of its benchmark and/or peer group for certain periods. With respect to any funds for which the Board has identified performance issues, the Board seeks to monitor 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 steps undertaken.
The Board’s determinations with respect to each Fund are summarized below.
For Nuveen
AMT-Free
Municipal Credit Income Fund (the
“AMT-Free
Municipal Credit Income Fund”), the Board noted that the Fund’s performance was below the performance of its blended benchmark for the
one-,
three- and five-year periods ended December 31, 2022 and March 31, 2023. Further, although the Fund ranked in the fourth quartile of its Performance Peer Group for the
one-year
periods ended December 31, 2022 and March 31, 2023, the Fund ranked in the third quartile for the three-year periods and first quartile for the five-year periods ended December 31, 2022 and March 31, 2023. In its review, the Board noted that the Performance Peer Group was classified as low for relevancy. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that in light of these factors, the Fund’s performance supported renewal of the Advisory Agreements.
For Nuveen Municipal Credit Income Fund (the “Municipal Credit Income Fund”), the Board noted that although the Fund’s performance was below the performance of its blended benchmark for the
one-,
three- and five-year periods ended December 31, 2022 and the Fund ranked in the fourth quartile of its Performance Peer Group for the
one-year
period ended December 31, 2022, the Fund ranked in the second quartile of its Performance Peer Group for the three-year period and first quartile for the five-year period ended December 31, 2022. In addition, although the Fund’s performance was below the performance of its blended benchmark for the
one-,
three- and five-year periods ended March 31, 2023, the Fund ranked in the third quartile of its Performance Peer Group for the
one-year
period ended March 31, 2023 and first quartile for the three- and five-year periods ended March 31, 2023. In its review, the Board noted that the Performance Peer Group was classified as low for relevancy. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that in light of these factors, the Fund’s performance supported renewal of the Advisory Agreements.
For Nuveen Municipal High Income Opportunity Fund (the “Municipal High Income Opportunity Fund”), the Board noted that the Fund’s performance was below the performance of its benchmark for the
one-,
three- and five-year periods ended December 31, 2022 and March 31, 2023. The Fund, however, ranked in the third quartile of its Performance Peer Group for the
one-year
periods, second quartile for the three-year periods and first quartile for the five-year periods ended December 31, 2022 and March 31, 2023. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that in light of these factors, the Fund’s performance supported renewal of the Advisory Agreements.
For Nuveen Municipal Credit Opportunities Fund (the “Municipal Credit Opportunities Fund”), the Board noted that although the Fund’s performance was below the performance of its benchmark for the
one-
and three-year periods ended December 31, 2022, the Fund ranked in the second quartile of its Performance Peer Group for such periods. In addition, although the Fund’s performance was below the performance of its benchmark and the Fund ranked in the fourth quartile of its Performance Peer Group for the
one-year
period ended March 31, 2023, the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the three-year period ended March 31, 2023. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that in light of these factors, the Fund’s performance supported renewal of the Advisory Agreements.
For Nuveen Dynamic Municipal Opportunities Fund (the “Dynamic Municipal Opportunities Fund”), the Board noted that the Fund’s performance was below the performance of its benchmark and the Fund ranked in the fourth quartile of its Performance Peer Group for the
one-year
periods ended December 31, 2022 and March 31, 2023. In its review, the Board noted that the Performance Peer Group was classified as low for relevancy. The Board recognized, however, that the Fund was relatively new with a performance history too limited to make a meaningful assessment of performance, and management deserved additional time to develop a performance record. The Board will continue to monitor the development of the Fund.
C. Fees, Expenses and Profitability

| 1. | Fees and Expenses

As part of its annual review, the Board generally reviewed, among other things, with respect to the Nuveen
closed-end
funds, the contractual management fee and actual management fee (i.e., the management fee after taking into consideration fee waivers and/or expense reimbursements, if any) paid by a fund to the Adviser in light of the nature, extent and quality of the services provided. The Board also considered the total operating expense ratio of a fund (after any fee waivers and/or expense reimbursements). More specifically, the Independent Board Members reviewed, among other things, each Nuveen
closed-end
fund’s actual management fee rate (after fee waivers and/or expense reimbursements, 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 take these limitations and differences into account when reviewing comparative peer 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.
280

In their review, the Independent Board Members considered, in particular, each Nuveen fund with a net total expense ratio (excluding investment-related costs of leverage for
closed-end
funds) of six basis points or higher compared to that of its peer average (each, an “Expense Outlier Fund”), including the Municipal Credit Opportunities Fund and the Dynamic Municipal Opportunities Fund, and an analysis as to the factors contributing to each such fund’s higher relative net total 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) 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 total expense ratio and fees (excluding leverage costs and leveraged assets for the
closed-end
funds) 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 Nuveen fund’s management fee and net total expense ratio in light of its performance history, including reviewing certain funds identified by the Adviser and/or the Board as having a higher net total expense ratio or management fee compared to their respective peers coupled with experiencing periods of challenged performance and considering the reasons for such comparative positions. In addition, with respect to
closed-end
funds that utilize leverage, the Independent Board Members recognized that certain assets attributable to a fund’s use of leverage may be included in the amount of assets upon which the advisory fee or
sub-advisory
fee is calculated. The Independent Board Members acknowledged the fact that a decision to employ leverage or increase a fund’s leverage which has the effect, all other things being equal, of increasing the assets upon which an advisory or
sub-advisory
fee is based (and, in turn, increasing the Adviser’s and applicable
sub-adviser’s
management fees), means that the Adviser and applicable
sub-adviser
may have a conflict of interest in determining whether to use or increase leverage. The Independent Board Members recognized, however, that the Adviser and
sub-advisers
would seek to manage the potential conflict by recommending to the Board to leverage the applicable fund or increase such leverage when the Adviser and/or
sub-adviser,
as applicable, has determined that such action would be in the best interests of the respective fund and its common shareholders and by periodically reviewing with the Board the fund’s performance and the impact of the use of leverage on that performance.
In their review of the fee arrangements for the Nuveen funds, the Independent Board Members also considered the management fee schedules, including the complex-wide and fund-level breakpoint schedules, as applicable. The Board noted that across the Nuveen fund complex, the complex-wide fee breakpoints reduced fees by approximately $62.4 million and fund-level breakpoints reduced fees by approximately $76.1 million in 2022.
With respect to the
Sub-Adviser,
the Board also considered, among other things, the
sub-advisory
fee schedule paid to the
Sub-Adviser
in light of the
sub-advisory
services provided to the respective Fund and comparative data of the fees the
Sub-Adviser
charges to other clients, if any. In its review, the Board recognized that the compensation paid to the
Sub-Adviser
is the responsibility of the Adviser, not the Funds.
The Independent Board Members noted that
(a) AMT-Free
Municipal Credit Income Fund and the Municipal Credit Income Fund each had an actual management fee that was slightly higher than the respective peer average, but a net total expense ratio that was in line with the respective peer average; (b) the Municipal High Income Opportunity Fund had an actual management fee that was in line with the peer average and a net total expense ratio that was below the peer average; and (c) the Municipal Credit Opportunities Fund and the Dynamic Municipal Opportunities Fund each had an actual management fee and a net total expense ratio that were higher than the respective peer averages. With respect to the net total expense ratios of the Municipal Credit Opportunities Fund and the Dynamic Municipal Opportunities Fund, the Independent Board Members noted that the differences in each such Fund’s investment strategy relative to the applicable peer set contributed to the differential and that each such Fund’s net total expense ratio was lower than initially projected prior to the Fund’s launch.
Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.

| 2. | Comparisons with the Fees of Other Clients

In evaluating 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 municipal Nuveen funds, such other clients may include retail and institutional municipal managed accounts
sub-advised
by the
Sub-Adviser,
municipal exchange-traded funds (“ETFs”)
sub-advised
by the
Sub-Adviser
that are offered by another fund complex, municipal managed accounts offered by an unaffiliated adviser and certain municipal private limited partnerships offered by Nuveen. The Board reviewed, among other things, the fee range and average fee of municipal retail advisory accounts and municipal institutional accounts, the
sub-advisory
fee the
Sub-Adviser
received for serving as
sub-adviser
to certain municipal ETFs offered outside the Nuveen family and the management fee rates paid by the municipal private limited partnerships operated by Nuveen.
281

Annual Investment Management Agreement Approval Process
(Unaudited) (continued)
In considering the comparative fee data, the Board recognized that differences, including but not limited to, the amount, type and level of services provided by the Adviser to the Nuveen funds compared to that provided to other clients as well as differences in investment policies; eligible portfolio assets and the manner of managing such assets; product structure; investor profiles; account sizes; and regulatory requirements contribute to the variations in the fee schedules. The Board acknowledged the wide range of services in addition to investment management that the Adviser had provided to the Nuveen funds compared to other types of clients as well as the increased entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the 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 more extensive services, regulatory requirements and legal liabilities, and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company compared to that required in advising other types of clients.

| 3. | Profitability of Fund Advisers

In their review, the Independent Board Members considered estimated profitability information of Nuveen as a result of its advisory services to the Nuveen funds as well as profitability data of other publicly traded asset management firms. Such profitability information included, among other things, gross and net revenue margins (excluding distribution) of Nuveen Investments, Inc. (“Nuveen Investments”) for services to the Nuveen funds on a
pre-tax
and
after-tax
basis for the 2022 and 2021 calendar years as well as the revenues earned (less any expense reimbursements/fee waivers) and expenses incurred by Nuveen Investments for its advisory activities to the Nuveen funds (excluding distribution and certain other expenses) for the 2022 and 2021 calendar years. The Independent Board Members also considered a summary of some of the key factors that impacted Nuveen’s profitability in 2022. In addition, the Board reviewed the revenues, expenses and operating margin
(pre-
and
after-tax)
the Adviser derived from its ETF product line for the 2022 and 2021 calendar years.
In developing the profitability data of the Adviser for its advisory services to the Nuveen funds, the Independent Board Members recognized the subjective nature of calculating profitability as the information is not audited and is necessarily dependent on cost allocation methodologies to allocate expenses throughout the complex and among the various advisory products. Given there is no perfect expense allocation methodology and that other reasonable and valid allocation methodologies could be employed and could lead to significantly different results, the Board reviewed, among other things, a description of the cost allocation methodologies employed to develop the financial information, a summary of the history of changes to the methodology over the years from 2010 through 2022, and a historical expense analysis of Nuveen Investments’ revenues, expenses and
pre-tax
net revenue margins derived from its advisory services to the Nuveen funds (excluding distribution) for the calendar years from 2017 through 2022. The Board had also appointed four Independent Board Members to serve as the Board’s liaisons, with the assistance of independent counsel, to meet with representatives of the Adviser and review the development of the profitability data and to report to the full Board.
In addition, the Board considered certain comparative operating margin data. In this regard, the Board reviewed the operating margins of Nuveen Investments compared to the adjusted operating margins of a peer group of asset management firms with publicly available data and the most comparable assets under management (based on asset size and asset composition) to Nuveen. The Board recognized that the operating margins of the peers were adjusted generally to address that certain services provided by the peers were not provided by Nuveen. The Board also reviewed, among other things, the net revenue margins
(pre-tax)
of Nuveen Investments on a company-wide basis and the net revenue margins
(pre-tax)
of Nuveen Investments derived from its services to the Nuveen funds only (including and excluding distribution) compared to the adjusted operating margins of the peer group for each calendar year from 2012 to 2022. Although the total company operating margins of Nuveen Investments were in the bottom half of the peer group range for 2022 and 2021, the Independent Board Members recognized the limitations of the comparative data given that peer 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) that 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”). Accordingly, the Board also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2022 and 2021 calendar years to consider the financial strength of TIAA. The Board recognized the benefit of an investment adviser and its parent with significant resources, particularly during periods of market volatility. The Board also noted the reinvestments Nuveen, its parent and/or other affiliates made into its business through, among other things, the investment of seed capital in certain Nuveen funds and continued investments in enhancements to technological capabilities.
In addition to Nuveen, the Independent Board Members considered the profitability of the
Sub-Adviser
from its relationships with the respective 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
after-tax)
for its advisory activities to the respective Nuveen funds for the calendar years ended December 31, 2022 and December 31, 2021. The Independent Board Members also reviewed a profitability analysis reflecting the revenues, expenses and revenue margin
(pre-
and
after-tax)
by asset type for the
Sub-Adviser
for the calendar years ending December 31, 2022 and December 31, 2021.
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.
282

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, whether these economies of scale have been appropriately shared with the funds and whether there is potential for realization of further economies of scale. Although the Board recognized that economies of scale are difficult to measure with any precision and certain expenses may not decline with a rise in assets, the Board considered that Nuveen shares the benefits of economies of scale, if any, in a number of ways including through the use of breakpoints in the management fee schedule, fee waivers and/or expense limitations, the pricing of funds at scale at inception and investments in Nuveen’s business which can enhance the services provided to the funds for the fees paid. In this regard, the Board recognized 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. With this structure, the Board noted that 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 unchanged or have declined, and the fund-level breakpoint schedules are designed to share economies of scale with shareholders if the particular fund grows. The Board noted, however, that although
closed-end
funds may make additional share offerings from time to time, the
closed-end
funds have a more limited ability to increase their assets because the growth of their assets will occur primarily from the appreciation of their investment portfolios.
As noted above, the Independent Board Members also recognized the continued reinvestment in Nuveen’s business to enhance its capabilities and services to the benefit of its various clients. The Board understood that many of these investments in the Nuveen business were not specific to individual Nuveen funds but rather incurred across of a variety of products and services pursuant to which the family of Nuveen funds as a whole may benefit. In addition, the Board also considered that Nuveen has provided, without raising advisory fees to the Nuveen funds, certain additional services, including, but not limited to, services required by new regulations and regulatory interpretations, and this was also a means of sharing economies of scale with the funds and their shareholders.
Based on its review, the Board was satisfied that the current fee arrangements together with the reinvestment in Nuveen’s 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 acknowledged that an affiliate of the Adviser may receive compensation for serving as a
co-manager
in the initial public offerings of new Nuveen
closed-end
funds (if any) and for serving as an underwriter on shelf offerings of existing Nuveen
closed-end
funds and reviewed the amounts paid for such services, if any, in 2021 and 2022.
In addition, the Independent Board Members noted that the various
sub-advisers
to the Nuveen funds do not generally benefit from soft dollar arrangements with respect to Nuveen fund portfolio transactions.
Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable in light of the services provided.
F. Other Considerations
The Independent Board Members did not identify any single factor discussed previously as
all-important
or controlling. The Independent Board Members concluded that the terms of each Advisory Agreement were reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed for an additional
one-year
period.
283

ITEM 4. | PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Nuveen AMT-Free Municipal Credit Income Fund

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

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

SERVICES THAT THE FUND’S AUDITOR BILLED TO THE FUND

Fiscal Year Ended |  | Audit Fees Billed to Fund 1 |  |  | Audit-Related Fees Billed to Fund 2 |  |  | Tax Fees Billed to Fund 3 |  |  | All Other Fees Billed to Fund 4 |
October 31, 2023 |  | $ | 33,000 |  |  | $ | 2,600 |  |  | $ | 0 |  |  | $ | 0 |
Percentage approved pursuant to pre-approval exception |  |  | 0 | % |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %
October 31, 2022 |  | $ | 31,580 |  |  | $ | 37,500 |  |  | $ | 0 |  |  | $ | 0 |
Percentage approved pursuant to pre-approval exception |  |  | 0 | % |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %

1 “Audit Fees” are the aggregate fees billed for professional services for the audit of the Fund’s annual financial statements and services provided in connection with statutory and regulatory filings or engagements.

2 “Audit Related Fees” are the aggregate fees billed for assurance and related services reasonably related to the performance of the audit or review of financial statements that are not reported under “Audit Fees”. These fees include offerings related to the Fund’s common shares and leverage.

3 “Tax Fees” are the aggregate fees billed for professional services for tax advice, tax compliance, and tax planning. These fees include: all global withholding tax services; excise and state tax reviews; capital gain, tax equalization and taxable basis calculation performed by the principal accountant.

4 “All Other Fees” are the aggregate fees billed for products and services other than “Audit Fees”, “Audit-Related Fees” and “Tax Fees”. These fees represent all “Agreed-Upon Procedures” engagements pertaining to the Fund’s use of leverage.

SERVICES THAT THE FUND’S AUDITOR BILLED TO THE

ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

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

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

Fiscal Year Ended |  | Audit-Related Fees Billed to Adviser and Affiliated Fund Service Providers |  |  | Tax Fees Billed to Adviser and Affiliated Fund Service Providers |  |  | All Other Fees Billed to Adviser and Affiliated Fund Service Providers |
October 31, 2023 |  | $ | 0 |  |  | $ | 0 |  |  | $ | 0 |
Percentage approved pursuant to pre-approval exception |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %
October 31, 2022 |  | $ | 0 |  |  | $ | 0 |  |  | $ | 0 |
Percentage approved pursuant to pre-approval exception |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %

NON-AUDIT SERVICES

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

Fiscal Year Ended |  | Total Non-Audit Fees Billed to Fund |  |  | Total Non-Audit Fees billed to Adviser and Affiliated Fund Service Providers (engagements related directly to the operations and financial reporting of the Fund) |  |  | Total Non-Audit Fees billed to Adviser and Affiliated Fund Service Providers (all other engagements) |  |  | Total |
October 31, 2023 |  | $ | 0 |  |  | $ | 0 |  |  | $ | 0 |  |  | $ | 0 |
October 31, 2022 |  | $ | 0 |  |  | $ | 0 |  |  | $ | 0 |  |  | $ | 0 |

“Non-Audit Fees billed to Fund” for both fiscal year ends represent “Tax Fees” and “All Other Fees” billed to Fund in their respective amounts from the previous table.

Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees.

The following section provides information on the portfolio managers at the Sub-Adviser:

ITEM 8(a)(1). | PORTFOLIO MANAGER BIOGRAPHIES

As of the date of filing this report, the following individuals at the Sub-Adviser (the “Portfolio Managers”) have primary responsibility for the day-to-day implementation of the registrant’s investment strategies:

Paul Brennan, CFA, manages a number of Nuveen tax-exempt fixed income portfolios and oversees several national and state-specific municipal closed-end funds. Paul began his career in the investment industry in 1991, as a municipal credit analyst for Flagship Financial, before becoming a portfolio manager in 1994. He joined Nuveen Investments in 1997, when Nuveen acquired Flagship Financial that year. Previously, he audited mutual funds and investment advisors as a member of Deloitte & Touche’s audit group. He earned his B.S. in Accountancy and Finance from Wright State University. He is a registered CPA (inactive) and a member of the American Institute of Certified Public Accountants. He also holds the Chartered Financial Analyst (CFA) designation and is a member of the CFA institute.

Steven M. Hlavin is a Managing Director of Nuveen Asset Management. As a member of the High Yield Municipal Portfolio Management Team, he is responsible for supporting all High Yield Municipal strategies and is specifically responsible for managing the Enhanced High Yield Municipal Bond, High Yield Municipal Opportunities LP, Municipal Opportunities and Short Duration High Yield Municipal Bond Strategies. He oversees a number of state-specific, tax-exempt portfolios including the Kansas Municipal Bond, Louisiana Municipal Bond and Wisconsin Municipal Bond Strategies. He is also responsible for the tender option bond/inverse floating rate program used by some of the firm’s closed-end and open-end funds. He joined the firm in 2003. Prior to his current position at the firm, he worked as a senior analyst responsible for risk management and performance measurement processes. He received his B.A. in Finance and Accounting and an M.B.A. in Finance from Miami University.

ITEM 8(a)(2). | OTHER ACCOUNTS MANAGED BY PORTFOLIO MANAGERS

Other Accounts Managed. In addition to managing the registrant, the Portfolio Managers are also primarily responsible for the day-to-day portfolio management of the following accounts:

Portfolio Manager |  | Type of Account Managed |  | Number of Accounts |  |  | Assets*
Paul Brennan |  | Registered Investment Company |  |  | 14 |  |  | $22.80 billion
|  | Other Pooled Investment Vehicles |  |  | 0 |  |  | $0
|  | Other Accounts |  |  | 4 |  |  | $377 million
Steven M. Hlavin |  | Registered Investment Company |  |  | 12 |  |  | $13.90 billion
|  | Other Pooled Investment Vehicles |  |  | 1 |  |  | $366 million
|  | Other Accounts |  |  | 0 |  |  | $0

* |  | Assets are as of October 31, 2023. None of the assets in these accounts are subject to an advisory fee based on performance.

POTENTIAL MATERIAL CONFLICTS OF INTEREST

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

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

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

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

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by a portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Conflicts of interest may also arise when the Sub-Adviser invests one or more of its client accounts in different or multiple parts of the same issuer’s capital structure, including investments in public versus private securities, debt versus equity, or senior versus junior/subordinated debt, or otherwise where there are different or inconsistent rights or benefits. Decisions or actions such as investing, trading, proxy voting, exercising, waiving or amending rights or covenants, workout activity, or serving on a board, committee or other involvement in governance may result in conflicts of interest between clients holding different securities or investments. Generally, individual portfolio managers will seek to act in a manner that they believe serves the best interest of the accounts they manage. In cases where a portfolio manager or team faces a conflict among its client accounts, it will seek to act in a manner that it believes best reflects its overall fiduciary duty, which may result in relative advantages or disadvantages for particular accounts.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Nuveen Asset Management or its affiliates, including TIAA, sponsor an array of financial products for retirement and other investment goals, and provide services worldwide to a diverse customer base. Accordingly, from time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual restrictions that arise due to another client account’s investments and/or the internal policies of Nuveen Asset Management, TIAA or its affiliates designed to comply with such restrictions. As a result, there may be periods, for example, when Nuveen Asset Management will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which investment limits have been reached.

The investment activities of Nuveen Asset Management or its affiliates may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries, in certain emerging or international markets, or are subject to corporate or regulatory ownership definitions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by Nuveen Asset Management or its affiliates for the Funds and other client accounts that may not be exceeded without the grant of a license or other regulatory or corporate consent. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of Nuveen Asset Management, on behalf of the Funds or other client accounts, to purchase or dispose of investments or exercise rights or undertake business transactions may be restricted by regulation or otherwise impaired. As a result, Nuveen Asset Management, on behalf of the Funds or other client accounts, may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when Nuveen Asset Management, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

ITEM 8(a)(3). | FUND MANAGER COMPENSATION

As of the most recently completed fiscal year end, the primary Portfolio Managers’ compensation is as follows:

Portfolio manager compensation consists primarily of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.

Base salary. A portfolio manager’s base salary is determined based upon an analysis of the portfolio manager’s general performance, experience and market levels of base pay for such position.

Cash bonus. A portfolio manager is eligible to receive an annual cash bonus that is based on three variables: risk-adjusted investment performance relative to benchmark generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), ranking versus Morningstar peer funds generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), and management and peer reviews.

Long-term performance award. A portfolio manager is eligible to receive a long-term performance award that vests after three years. The amount of the award when granted is based on the same factors used in determining the cash bonus. The value of the award at the completion of the three-year vesting period is adjusted based on the risk-adjusted investment performance of Fund(s) managed by the portfolio manager during the vesting period and the performance of the TIAA organization as a whole.

Profits interest plan. Portfolio managers are eligible to receive profits interests in Nuveen Asset Management and its affiliate, Teachers Advisors, LLC, which vest over time and entitle their holders to a percentage of the firms’ annual profits. Profits interests are allocated to each portfolio manager based on such person’s overall contribution to the firms.

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