Chair’s Letter to Shareholders Anchor

Dear Shareholders,

As 2020 draws to a close, the concerns that dominated much of the year are beginning to show signs of easing. COVID-19 vaccines are being administered around the world, with several of the vaccine candidates announcing high efficacy rates during their phase 3 trials. Markets took a generally positive view of Joe Biden winning the Electoral College, with Congress’s final confirmation of the Electoral College vote anticipated on January 6, 2021. The U.S. economy has made a significant, although incomplete, turnaround from the depths of a historic recession. In December, Congress passed another $900 billion in aid to individuals and businesses, extending some of the programs enacted earlier in the crisis. The bill’s next step is the President’s review and his approval or disapproval. Ongoing fiscal and monetary stimulus along with widening vaccine distribution have bolstered confidence that a semblance of normalcy can return in 2021.

While the markets’ longer-term outlook has brightened, we expect intermittent bouts of volatility to continue into the new year. COVID-19 cases are still alarmingly high in some regions, and the renewed restrictions on social and business activity taken by local and, in some cases, national authorities will undoubtedly hinder the economy’s momentum. The pandemic’s course can still be unpredictable. The timeline of vaccine rollouts depends on many variables, public confidence can shift and real-world efficacy remains to be seen. Additionally, the outcome of the Senate majority – which determines whether the government will be under split control or a Democrat majority – rests with Georgia’s two run-off elections on January 5, 2021. Nevertheless, short-term market fluctuations can provide opportunities to invest in new ideas as well as upgrade existing positioning, within our goal of providing long-term value for our shareholders.

The new year can be an opportune time to assess your portfolio’s resilience and readiness for what may come next. 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.

Sincerely,

Terence J. Toth Chair of the Board December 22, 2020

These Funds feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen Fund Advisors, LLC, the Funds’ investment adviser. Portfolio managers John V. Miller, CFA, Steve M. Hlavin, Paul L. Brennan, CFA, Scott R. Romans, PhD and Timothy T. Ryan, CFA discuss U.S. economic and municipal market conditions, key investment strategies and the twelve-month performance of NVG, NZF, NMZ and NMCO and NDMO in the abbreviated reporting period since its inception on August 26, 2020. Paul has managed NVG since 2006, Scott assumed portfolio management responsibility for NZF in 2016, John has managed NMZ since its inception in 2003, John and Steve have managed NMCO since its inception in 2019 and John and Tim have managed NDMO since its inception in 2020.

During May and October 2019, the Board of Trustees and Shareholders approved the merger of the Nuveen Connecticut Quality Municipal Income Fund (NTC) to the acquiring Fund, the Nuveen AMT-Free Municipal Credit Income Fund (NVG). The merger was completed prior to the open of business on November 18, 2019.

What factors affected the U.S. economy and financial markets during the twelve-month reporting period ended October 31, 2020?

The U.S. economy rebounded more quickly than expected from the deep downturn caused by the COVID-19 crisis and containment measures. As business and social activities were drastically restricted in March and April 2020 to slow the spread of COVID-19, U.S. gross domestic product (GDP) shrank 31.4% on an annualized basis in the second quarter of 2020 (following a 5% decline in the first quarter), according to the Bureau of Economic Analysis (BEA) “third” estimate. GDP measures the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes. Government relief programs provided significant aid to individuals and businesses as the economy began reopening in May 2020, which helped the economy bounce back strongly over the summer months. GDP rose 33.1% in the third quarter of 2020, according to the BEA’s “second” estimate. While the third quarter gain was historic, the economy remained below pre-pandemic growth levels. GDP growth was 2.4% in the fourth quarter of 2019 and 2.2% for 2019 overall.

Portfolio Managers’ Comments (continued)

Consumer spending, the largest driver of the economy, was well supported earlier in this reporting period by low unemployment, wage gains and tax cuts. However, the COVID-19 crisis containment measures drove a significant drop in consumer spending and a sharp rise in unemployment starting in March 2020. The Bureau of Labor Statistics said the unemployment rate rose to 6.9% in October 2020 from 3.6% in October 2019. As of October 2020, slightly more than half of the 22 million jobs lost in March and April 2020 have been recovered. The average hourly earnings rate appeared to soar, growing at an annualized rate of 4.5% in October 2020, despite the spike in unemployment. Earnings data was skewed by the concentration of job losses in lower-wage work, which effectively eliminated most of the low-wage data, resulting in an average of mostly higher numbers. The overall trend of inflation remained muted, as decreases in gasoline, apparel and transportation prices offset an increase in food prices. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 1.2% over the twelve-month reporting period ended October 31, 2020 before seasonal adjustment.

Prior to the COVID-19 crisis recession, the U.S. Federal Reserve (the Fed) had reduced its benchmark interest rate to support the economy’s slowing growth. The Fed also stopped shrinking its bond portfolio sooner than scheduled and began buying short-term Treasury bills to help money markets operate smoothly and maintain short-term borrowing rates at low levels.

As the health and economic crisis deepened, the Fed enacted an array of emergency measures in March 2020 to stabilize the financial system and support the markets, including cutting its main interest rate to near zero, offering lending programs to aid small and large companies and allowing unlimited bond purchases, known as quantitative easing. There were no policy changes at the Fed’s April, June and July 2020 meetings, where Chairman Powell reiterated a commitment to keep rates near zero until the economy recovers and maintained a cautious outlook for the U.S. economy. Also at the July 2020 meeting, the Fed extended some of its pandemic funding facilities by another three months to December 2020. At the annual Jackson Hole Economic Symposium, held virtually in August 2020, the Fed announced a change in inflation policy to average inflation targeting. Under this regime, the Fed will tolerate the inflation rate temporarily overshooting the target rate to offset periods of below-target inflation, so that inflation averages a 2% rate over time. The Fed provided further clarification of the new inflation policy and left the benchmark interest rate unchanged at its September 2020 meeting. (As expected, there were no policy changes at the Fed’s November 2020 meeting, which occurred after the close of this reporting period.)

In March and April 2020, the U.S. government approved three aid packages. These included $2 trillion allocated across direct payments to Americans, an expansion of unemployment insurance, loans to large and small businesses, funding to hospitals and health agencies and support to state and local governments, as well as more than $100 billion in funding to health agencies and employers offering paid leave. As some of these programs began to expire, additional relief measures were under discussion in Congress, but a final deal had not been reached as of the end of this reporting period. The election outcome, subsequent to the close of the reporting period, did not change expectations for a stimulus bill, but the timing and size remained uncertain.

The COVID-19 crisis rapidly dwarfed all other market concerns starting in late February 2020. Equity and commodity markets sold-off and safe-haven assets rallied in March 2020 as China, other countries and then the United States initiated quarantines, restricted travel and shuttered factories and businesses. The potential economic shock was particularly difficult to assess, which amplified market volatility. An ill-timed oil price war between the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC member Russia, which caused oil prices to plunge in March 2020, exacerbated the market sell-off.

Geopolitical uncertainty remained elevated with the U.S. presidential election, the Brexit transition period winding down and U.S.-China relations deteriorating. While markets remained concerned about the potential for a disputed outcome, the next round of fiscal stimulus was expected to follow the presidential election. In Europe, the EU and U.K. continued to negotiate, but had not yet reached, a final Brexit agreement after the U.K. formally exited at the end of January 2020 and triggered the one-year transition period (which ends on December 31, 2020). Although China and the U.S. signed a “phase one” trade deal in January 2020, tensions continued to flare over other trade and technology/security issues, Hong Kong’s sovereignty and the management of the COVID-19 crisis.

Despite the severe sell-off in March 2020, municipal bonds managed positive performance over the twelve-month reporting period. For most of the reporting period, a significant decline in interest rates drove municipal bond prices higher, with positive technical and fundamental conditions also supporting credit spread tightening. Prior to the emergence of the novel coronavirus, interest rates had been pressured lower by signs that the economy’s momentum was slowing, a more dovish central bank policy, geopolitical tensions (especially regarding trade) and bouts of equity market volatility. Then, from late February through March 2020, coronavirus risks permeated the markets, sending U.S. Treasury yields to historic lows. Rate volatility increased sharply in that six-week period. As liquidity became stressed, investors began to liquidate any asset possible, including municipal bonds. Municipal bond prices declined rapidly (and yields spiked higher), amid rampant selling across both the high grade and high yield segments that was exacerbated in some cases by exchange-traded fund and closed-end fund selling. Municipal bond prices became severely dislocated from Treasury prices. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. Monetary and fiscal interventions from the Fed and U.S. government helped the market recover in April and May, although spreads remain wider than average as of the end of the reporting period. The municipal yield curve steepened over this reporting period, with a pronounced drop in yields at the short end of the curve spearheading the steepening.

Prior to the market turmoil in March 2020, municipal bond gross issuance nationwide had been robust. The overall low level of interest rates encouraged issuers to continue to actively refund their outstanding debt. In these transactions the issuers are issuing new bonds and taking the bond proceeds and redeeming (calling) old bonds. These refunding transactions have ranged from 30% to 60% of total issuance over the past few years. Thus, the net issuance (all bonds issued less bonds redeemed) is actually much lower than the gross issuance. So, while gross issuance volume has been adequate, the net has not and this was an overall positive technical factor on municipal bond investment performance in recent years. Notably, taxable municipal bond issuance has increased meaningfully since the advent of the Tax Cut and Jobs Act of 2017, which prohibits municipal issuers from issuing new tax-exempt bonds to pre-refund existing tax-exempt bonds. However, municipalities have taken advantage of the low interest rate environment and the strong demand for yield to issue taxable municipal debt, enabling them to save on net interest costs while adding to the scarcity value of tax-exempt issues.

Municipal bond funds saw consistently positive cash flows throughout 2019 and into early 2020, then suffered significant outflows in March 2020, particularly from high yield municipal bond funds. After the market stabilized in April 2020, fund flows subsequently turned positive again, bringing year-to-date flows through October 2020 back into positive territory. Demand has been resilient even though municipal defaults, as expected, have increased somewhat in 2020. Notably, default activity has occurred mainly in sectors with greater COVID-19 risk exposure, such as senior living, corporate-backed and real estate-backed. Additionally, while municipal credit ratings remain under pressure given the uncertain economic outlook, a wave of downgrades has not materialized. With interest rates in the U.S. and globally remaining near all-time lows, the appetite for yield has continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have adjusted to the 2017 tax law, which caps the state and local tax (SALT) deduction for individuals, there has been increased demand for tax-exempt municipal bonds, especially in states with high income taxes and/or property taxes.

What key strategies were used to manage the four Funds during the twelve-month reporting period and NDMO during the abbreviated reporting period ended October 31, 2020 and how did these strategies influence performance?

The Nuveen AMT-Free Municipal Credit Income Fund seeks to provide current income exempt from regular federal income tax 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. The Fund invests in municipal securities that are exempt from federal income taxes. The Fund uses leverage. By investment policy, the Fund may invest up to 55% of its managed assets in municipal securities rated at the time of investment Baa/BBB and below or judged to be of comparable quality by the Fund’s portfolio management team.

Portfolio Managers’ Comments (continued)

The Nuveen Municipal Credit Income Fund seeks to provide current income exempt from regular federal income tax by investing in an actively managed portfolio of tax-exempt municipal securities. Up to 55% of its managed assets may be in securities rated BBB and below at the time of purchase or, if unrated, judged to be of comparable quality by the Fund’s portfolio management team, and the Fund uses leverage.

The Nuveen Municipal High Income Opportunity Fund seeks 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. The Fund invests in municipal securities that are exempt from federal income taxes; the Fund uses leverage. By investment policy, up to 75% of its managed assets may be invested in municipal securities rated, at the time of investment, Baa/BBB or lower by at least one nationally recognized statistical rating organization including below investment grade securities, or unrated securities judged by the manager to be of comparable quality. No more than 10% of the Fund’s managed assets may be invested in municipal securities rated below B3/B-, or that are unrated but judged to be of comparable quality by the Fund’s portfolio management team.

The Nuveen Municipal Credit Opportunities Fund seeks to provide a high level of current income exempt from regular U.S. federal income tax and secondarily, total return. The Fund invests primarily in high yielding, low- to medium-quality municipal securities that, at the time of investment, are rated Baa/BBB or lower or, if unrated, are judged to be of comparable quality by the Fund’s portfolio management team. No more than 30% of the Fund’s managed assets will be in municipal securities rated CCC+/Caa1 or lower at the time of investment or unrated but judged to be of comparable quality. No more than 10% of the Fund’s managed assets can be in defaulted securities or securities of issuers in bankruptcy or insolvency proceedings at the time of investment. The Fund uses leverage and has a 12-year term with the potential to convert to perpetual.

The Nuveen Dynamic Municipal Opportunities Fund seeks to provide a total return through income exempt from regular federal income taxes and capital appreciation. The Fund invests primarily in municipal securities, the income on which is exempt from regular U.S. federal income tax. The Fund may invest in municipal securities of any maturity and credit quality, without limit in below investment grade municipal securities rated BB+/Ba1 or lower at the time of investment or unrated but judged to be of comparable quality by the Fund’s portfolio management team, and without limit in municipal securities that generate income subject to the U.S. federal alternative minimum tax (“AMT Bonds”). No more than 20% of Managed Assets can be in taxable debt obligations, including taxable municipal securities, and no more than 10% of Managed Assets can be in defaulted securities or securities of issuers in bankruptcy or insolvency proceedings at the time of investment. The Fund uses leverage and has a 12-year term with the potential to convert to perpetual.

Despite historic volatility in the municipal market during March and April 2020, municipal bond performance was positive during the twelve-month reporting period overall. Municipal yields fell, in concert with a steep drop in Treasury yields as the U.S. economy fell into a deep recession amid the virus lockdown. The decline was more dramatic at the short end of the municipal yield curve, which steepened the yield curve over the reporting period. Demand for municipal bonds recovered after the March-April 2020 sell-off, with mutual fund inflows resuming a positive trend (although more so for high grade than high yield municipal funds) and the market absorbing significant supply. With demand normalizing, high grade municipal bonds have made a full recovery from the March-April 2020 COVID-19 crisis, while high yield credit spreads have narrowed meaningfully but remained wider than where they began during the reporting period.

We continued to take a bottom-up approach to discovering sectors that appeared undervalued as well as individual credits that we believed had the potential to perform well over the long term. Our trading activity continued to focus on pursuing the Funds’ investment objectives.

NVG’s trading activity was mainly driven by bonds rolling off the portfolio due to bond calls and maturities. One of the larger refundings during the reporting period was Buckeye Tobacco Settlement bonds, which the state of Ohio refunded in March 2020 and issued new replacement bonds. NVG, NZF, NMZ and NMCO owned the legacy bonds and bought some of the replacement bonds. NVG also held Los Angeles County tobacco bonds that were refunded during this reporting period. Early in the COVID-19 related

sell-off, we took some small precautionary steps to prepare for the possibility of deleveraging, including delaying the reinvestment of cash proceeds from called bonds and coupon income. However, market liquidity, although stressed, remained sufficient and deleveraging was not needed. After the sell-off, the market was favorable for executing tax-loss swaps. This strategy entailed selling depreciated bonds with lower yields and buying similarly structured but higher yielding bonds. This approach was implemented to enhance NVG’s income earning capability and seek to make the Fund more tax efficient. The portfolio’s overall positioning was relatively unchanged over the reporting period. We bought bonds across a range of sectors, including health care, transportation, tax-supported (such as Puerto Rico and Illinois debt) and housing, and across the credit quality spectrum, although there was a slight skew toward investment grade bonds.

In NZF, prior to the March-April 2020 sell-off, municipal yields were very low and credit spreads were tight, providing fewer attractive relative value opportunities. We worked to reinvest call and maturity proceeds into some A rated names we considered suitable long-term investments as well as some highly liquid, AA rated placeholder credits to keep the Fund fully invested until more attractive opportunities were available in the marketplace. NZF also held legacy Buckeye Tobacco bonds that were refunded, and reinvested some of proceeds into the new issue replacement bonds and rotated some into Puerto Rico sales tax revenue bonds (known as COFINAs), where longer-term fundamentals looked more attractive. After the COVID-19 crisis sell-off, we also took advantage of the favorable environment for tax loss swaps in NZF’s portfolio, which were implemented in three approaches: first, higher prevailing yields on AAA rated paper enabled us to swap out of high grade positions into other, relatively higher yielding high grade positions with similar risk characteristics; second, rotating some of the Fund’s high grade, lower yielding placeholder bonds into lower rated, higher yielding investments, as capital outflows from lower rated bonds provided attractive buying opportunities in airports and airline-related, health care, public transportation and certain Manhattan real estate redevelopment bonds; and third, making one-for-one exchanges within high yield positions, including COFINAs, health care, convention center related, airports and state of Illinois, to reset embedded yields higher. As the market stabilized and the high yield liquidity crisis abated, the tax loss swap opportunity waned and we refocused on credit fundamentals. NFZ bought primarily A rated debt in airports and health care, which were funded from the proceeds of called and maturating bonds.

For most of the reporting period, NMZ worked to reinvest coupon income, call proceeds, payments from sinking funds (a fund formed by periodically setting aside money for the gradual repayment of a debt) and capital inflows from secondary share marketing. Some of the larger refundings affecting NMZ during this reporting period were Buckeye Tobacco, high coupon toll roads and high coupon hospitals. We added to some high performing sectors, such as tobacco and COFINAs, in the secondary market. We also continued to invest in individual primary market opportunities, including land secured (Castle Oaks Metropolitan District in Denver), charter schools (Renaissance Charter School in Florida), single family housing (especially suburban areas), New York Metropolitan Transportation Authority and airline bonds backed by important airports (e.g., New York JFK International backed by American Airlines, Denver Special Facilities backed by United Airlines and Port of Seattle backed by Delta Air Lines). There were no material sells for credit or duration reasons.

NMCO’s invest-up period ended during the first half of the reporting period. By the March 2020 sell-off, the Fund had all of its cash invested but approximately 20% of the portfolio was held in mid-grade bonds, which served as temporary placeholders while we worked to source opportunities in higher yielding, lower rated bonds. The Fund was therefore well positioned to make advantageous relative value swaps in March 2020, when market weakness provided opportunity to buy into long-term high yield positions at attractive spreads. As a result, trading activity was elevated in March 2020 as we worked to set up the Fund for a high yield recovery. Industrial development revenue (IDR) bonds are NMCO’s largest sector exposure, which tend to be more economically sensitive and could benefit from further spread normalization.

Additionally, at the end of March 2020, NMCO delevered to help mitigate net asset value volatility and manage the leverage ratio within the stated target. These efforts influenced the timing and size of the Fund’s distribution cut. Under normal market conditions, portfolio managers would be able to take mitigating steps, through tax loss bond exchanges and other strategies, to offset the impact of unwinding leverage. However, due to the unprecedented velocity of the market’s sell-off and the compressed time period

in which it occurred, we believe it was in the best long-term interest of our shareholders to take these prudent actions in the short term. We believe this can ultimately help enhance earnings over the long run.

Also during this reporting period, NVG, NZF, NMZ and NMCO acquired shares in Energy Harbor when their holdings of certain municipal bonds issued by FirstEnergy Solutions were converted into Energy Harbor equity as part of FirstEnergy Solution’s emergence from bankruptcy protection. The share price appreciated strongly post its March 2020 issuance. In July 2020, the stock suffered a correction on negative headline news about the predecessor company and its former parent company. During the reporting period, the negative performance impact to NZF, NMZ and NMCO was relatively muted and the combined equity and debt position was a detractor for NVG. Over time, we expect to sell these shares and reinvest the proceeds into municipal bonds.

NDMO began operations in late August 2020 and since then we have worked to invest the portfolio in investment grade and high yield opportunities that support high income earnings and offer total return potential.

As of October 31, 2020, the Funds continued to use inverse floating rate securities. We employ inverse floaters for a variety of reasons, including duration management and income and total return enhancement.

How did the four Funds perform during the twelve-month reporting period and NDMO during the abbreviated reporting period ended October 31, 2020?

The tables in each Fund’s Performance Overview and Holding Summaries section of this report provide the Funds’ total returns at net asset value (NAV) for the period ended October 31, 2020. Each Fund’s total returns at NAV are compared with the performance of a corresponding market index.

For the twelve months ended October 31, 2020, the total returns at NAV for NVG, NZF and NMZ underperformed the return for the national S&P Municipal Bond Index. NVG and NZF underperformed the return for the secondary benchmark (composed of 60% S&P Municipal Bond Investment Grade Index and 40% S&P Municipal Bond High Yield Index), and NMZ and NMCO underperformed the return on the S&P Municipal Yield Index. For the abbreviated reporting period, the total returns at NAV for NDMO outperformed the return of the S&P Municipal Bond Index.

The main factors influencing the Funds’ relative performance in this reporting period were yield curve and duration positioning, credit quality allocation and sector allocation. In addition, the use of regulatory leverage was an important factor affecting performance of the Funds. Leverage is discussed in more detail later in the Fund Leverage section of this report.

The main drivers of NVG and NZF’s relative performance were yield curve and duration positioning, credit quality allocations and sector allocations. NVG and NZF were favorably positioned for the falling interest rate environment during this reporting period. The two Funds were positioned with longer durations than the benchmark, with overweights to longer duration bonds and underweights to shorter duration bonds, which was advantageous because longer bonds generally outperformed.

Credit ratings allocations detracted from NVG and NZF’s relative performance, offsetting the positive contribution of duration and yield curve positioning. The largest drag came from overweight allocations to bonds rated BBB and lower, which performed poorly during the March-April 2020 market weakness and hadn’t fully recovered by the end of the reporting period.

The volatility during the reporting period skewed performance at the sector level. Overall, sector allocations adversely affected NVG but were modestly beneficial for NZF. The tobacco sector performed strongly, largely due to the refundings and restructurings of some legacy tobacco issues (such as Buckeye Tobacco) that occurred during the reporting period. The defensively oriented tax-supported and utilities sectors also held up well, as did the pre-refunded sector, due to its high credit quality composition. Conversely, the weaker performers were more economically sensitive sectors and/or those with greater exposure to coronavirus impacts such as IDR, health care (especially senior living facilities), transportation and higher education.

NMZ’s performance, which is primarily compared to the S&P Municipal Yield Index, continued to be driven by our bottom-up credit selection. Within the high yield municipal market, there was a wide dispersion of returns by sector and individual security, resulting in a mix of very strong and very weak performers within NMZ’s portfolio. The best performing sectors were tobacco, Puerto Rico,

dedicated tax and land secured, while the weakest groups were senior living facilities and IDRs. Hospitals, airports and multi-family housing fell in the middle of the pack. NMZ holds underweight allocations relative to the benchmark’s much higher weightings in tobacco and Puerto Rico bonds, given our views about the risk-reward offered by these sectors, and this was the main detractor from relative performance.

Partially offsetting the relative weakness, however, were our relatively lower exposures to the two weakest performing sectors, IDRs and senior living facilities, as well as the Fund’s higher exposure to land secured debt, which performed well. Other notable detractors were individual securities that suffered from short-term, event-specific headwinds. For example, pandemic-related concerns drove valuations meaningfully lower for Brightline (formerly Virgin Trains USA), a South Florida high-speed passenger rail project, and American Dream, the retail and entertainment mega-plex at the Meadowlands, New Jersey. However, our research suggests these bonds are structured to weather short-term disruption and investors may be overlooking the longer-term potential for these projects. Overall, the underperformance of these and other laggards in NMZ’s portfolio has been perception-driven more than reality-driven, in our opinion. The default rate in the Fund has remained very low, and in most sectors, the technicals rather than fundamentals have exaggerated performance, whether to the upside or the downside.

NMCO’s performance is also primarily compared to the S&P Municipal Yield Index. The Fund’s performance was shaped by three major events during the reporting period. The first was the Fund’s invest-up period, which coincided with the first half of the reporting period. There was a natural drag on performance due to the Fund putting money to work during the strong performing market preceding the advent of the COVID-19 crisis. The second event was the March-April 2020 sell-off. The Fund underperformed significantly during the market panic, due to its leveraged duration and higher exposure to high yield bonds in general, where spreads widened sharply. However, the prevailing market also enabled us to make advantageous relative value swaps out of the placeholder investment grade bonds into longer-term high yield exposures that positioned the Fund for a high yield recovery. The third event, the municipal market’s stabilization and the high yield segment’s partial recovery over the summer months, benefited the Fund’s high yield positioning. Although NMCO’s overweight to the IDR sector, which hasn’t yet fully recovered, and underweights to the stronger performing dedicated tax and Puerto Rico sectors were all detractors from relative performance, the Fund benefited from an underweight to senior living facilities, the worst performing segment, and favorable security selection in the tobacco sector.

During the abbreviated reporting period, NDMO outperformed the benchmark S&P Municipal Bond Index, primarily due to strong security selection. Top performing positions included Southern Ohio Port Authority PureCycle, Chicago Transit Authority sales tax revenue, Delta Air Lines - LaGuardia Airport Terminal and Colorado International Metropolitan District Number 8. The weakest performing holdings included New York MTA, selected Puerto Rico general obligation bonds, Big River Steel and Talen Energy. The Fund’s longer duration positioning, partially managed with the use of inverse floaters, was somewhat disadvantageous as interest rates drifted higher in the abbreviated reporting period.

Fund Leverage Anchor

IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES 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 a Fund earns on its portfolio of long-term bonds that it has bought with the proceeds of that leverage. This has been particularly true in the recent market environment where short-term rates have been low by historical standards.

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 municipal bonds acquired through the use of leverage increase in value, but will also experience a correspondingly larger decline in their net asset value if the bonds 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 tax-exempt interest rates. While fund leverage expenses are somewhat higher than their recent lows, leverage nevertheless continues to provide the opportunity for incremental common share income, particularly over longer-term periods.

The use of leverage had a negative impact on the total return performance of NVG, NZF, NMZ and NMCO and a negligible impact on the total return performance of NDMO over the reporting period.

As of October 31, 2020, the Funds’ percentages of leverage are as shown in the accompanying table.

	NVG	NZF	NMZ	NMCO	NDMO
Effective Leverage*	38.00%	38.09%	35.25%	40.88%	14.54%
Regulatory Leverage*	35.04%	37.62%	7.35%	39.73%	0.00%

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.

The following information regarding the Funds’ distributions is current as of October 31, 2020. 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.

Monthly Distributions (Ex-Dividend Date)	Per Common Share Amounts — NVG	NZF	NMZ	NMCO	NDMO

Taxable-Equivalent Yield**	8.76 %	9.07 %	9.35 %	10.69 %	10.34 %

*	Distribution paid in December 2019.
**	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 an 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.

Each Fund seeks to pay regular monthly dividends out of its net investment income at a rate that reflects its past and projected net income performance. To permit 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 Note 6 — Income Tax Information for additional information regarding the amounts of undistributed net ordinary income and undistributed net long-term capital gains and the character of the actual distributions paid by the Fund during the period.

Table of Contents

All monthly dividends paid by each Fund during the current reporting period were paid from net investment income. If a portion of the Fund’s monthly distributions is sourced or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders will be notified of those sources. For financial reporting purposes, the per share amounts of 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 in Note 6 — Income Tax Information within the Notes to Financial Statements of this report.

We have audited the accompanying statements of assets and liabilities 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 (the Funds), including the portfolios of investments, as of October 31, 2020, the related statements of operations and cash flows for the year then ended (the period from August 26, 2020 (commencement of operations) to October 31, 2020 for Nuveen Dynamic Municipal Opportunities Fund), the statements of changes in net assets for each of the years in the two-year period then ended (the year then ended and the period from September 16, 2019 (commencement of operations) to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund and the period from August 26, 2020 to October 31, 2020 for Nuveen Dynamic Municipal Opportunities Fund), and the related notes (collectively, the financial statements) and the financial highlights for each of the years in the five-year period then ended (the year then ended and the period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund and the period from August 26, 2020 to October 31, 2020 for Nuveen Dynamic Municipal Opportunities Fund). 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, 2020, the results of their operations and cash flows for the year then ended (the period from August 26, 2020 to October 31, 2020 for Nuveen Dynamic Municipal Opportunities Fund), the changes in their net assets for each of the years in the two year period then ended (the year then ended and the period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund and the period from August 26, 2020 to October 31, 2020 for Nuveen Dynamic Municipal Opportunities Fund), and the financial highlights for each of the years in the five year period then ended (the year then ended and the period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund and the period from August 26, 2020 to October 31, 2020 for Nuveen Dynamic Municipal Opportunities Fund), 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, 2020, by correspondence with custodians and brokers or other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

/s/ KPMG LLP

We have served as the auditor of one or more Nuveen investment companies since 2014.

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

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

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.

The end of the reporting period for the Funds is October 31, 2020. The period covered by these Notes to Financial Statements for NVG, NZF, NMZ, and NMCO is the fiscal year ended October 31, 2020, while the reporting period for NDMO is the period August 26, 2020 (commencement of operations) through October 31, 2020 (collectively the “current fiscal period”).

Investment Adviser and Sub-Adviser

The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, 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 Merger

Effective prior to the opening of business on November 18, 2019, Nuveen Connecticut Quality Municipal Income Fund (NTC) (the “Target Fund”) was merged into NVG (the “Acquiring Fund”) (the “Merger”).

For accounting and performance reporting purposes, the Acquiring Fund is the survivor.

Upon the closing of the Merger, the Target Fund transferred its assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund and the assumption by the Acquiring Fund of the liabilities of the Target Fund. The Target Fund was then liquidated, 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 Merger (including for this purpose fractional Acquiring Fund shares to which shareholders were entitled). Holders of preferred shares of the Target Fund receive on a one-for-one basis newly issued preferred shares of the Acquiring Fund, in exchange for preferred shares of the Target Fund held immediately prior to the Merger. Details of the Merger are further described in Note 9 – Fund Merger.

Other Matters

The outbreak of the novel coronavirus (“COVID-19”) and subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the calendar quarter ended March 31, 2020. The worldwide spread of COVID-19 has created significant uncertainty in the global economy. The duration and extent of COVID-19 over the long-term cannot be reasonably estimated at this time. The ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Funds’ normal course of business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Management continues to monitor and evaluate this situation.

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 the accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services—Investment Companies. The NAV for financial reporting purposes may differ from the NAV for processing security and common share transactions. The NAV for financial reporting purposes includes security and common share transactions through the date of the report. Total return is computed based on the NAV used for processing security and common share transactions. The following is a summary of the significant accounting policies consistently followed by the Funds.

Compensation

The Funds pay no compensation directly to those of its trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Funds’ Board of Trustees (the “Board”) has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

Distributions to Common Shareholders

Distributions to common shareholders are recorded on the ex-dividend date. The amount, character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Indemnifications

Under the 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 expect 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 Derivative 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.

The Funds’ investments subject to netting agreements as of the end of the reporting period, if any, are further described in Note 4 – Portfolio Securities and Investments in Derivatives.

Organizational Expenses

Prior to the commencement of operations for NDMO on August 26, 2020, the Fund had no operations other than those related to organizational matters, the Fund’s initial contribution of $100,005, by the Adviser.

New Accounting Pronouncements and Rule Issuances

FASB Accounting Standards Update (“ASU”) 2017-08 (“ASU 2017-08”) Premium Amortization on Purchased Callable Debt Securities

The FASB has issued ASU 2017-08, which shortens the premium amortization period for purchased non-contingently callable debt securities. ASU 2017-08 specifies that the premium amortization period ends at the earliest call date, for purchased non-contingently callable debt securities. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. During the current fiscal period, ASU 2017-08 became effective for the Funds and it did not have a material impact on the Funds’ financial statements.

Notes to Financial Statements (continued)

Reference Rate Reform

In March 2020, FASB issued ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The main objective of the new guidance is to provide relief to companies that will be impacted by the expected change in benchmark interest rates at the end of 2021, when participating banks will no longer be required to submit London Interbank Offered Rate (LIBOR) quotes by the UK Financial Conduct Authority (FCA). The new guidance allows companies to, provided the only change to existing contracts are a change to an approved benchmark interest rate, account for modifications as a continuance of the existing contract without additional analysis. For new and existing contracts, the Funds may elect to apply the optional expedients as of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the optional expedients, but is currently assessing the impact of the ASU’s adoption to the Funds’ financial statements and various filings.

Investment Valuation and Fair Value Measurements

The Funds’ investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. U.S. GAAP establishes the three-tier hierarchy which is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect management’s assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).

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

A description of the valuation techniques applied to the Funds’ major classifications of assets and liabilities measured at fair value follows:

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

Investments in investment companies are valued at their respective NAVs on the valuation date and are generally classified as Level 1.

Equity securities and exchange-traded funds listed or traded on a national market or exchange are valued based on their sale price at the official close of business of such market or exchange on the valuation date. Foreign equity securities are valued at the last sale price or official closing price reported on the exchange where traded and converted to U.S. dollars at the prevailing rates of exchange on the date of valuation. To the extent these securities are actively traded and that valuation adjustments are not applied, they are generally classified as Level 1. If there is no official close of business, then the latest available sale price is utilized. If no sales are reported, then the mean of the latest available bid and ask prices is utilized and are generally classified as Level 2.

Any portfolio security or derivative for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued at fair value, as determined in good faith using procedures approved by the Board. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. To the extent the inputs are observable and timely, the values would be classified as Level 2 of the fair value hierarchy; otherwise they would be classified as Level 3.

Portfolio Securities and Investments in Derivatives 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 of the 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.

Table of Contents

Notes to Financial Statements (continued)

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:

Floating Rate Obligations Outstanding	NVG	NZF	NMZ	NMCO	NDMO
Floating rate obligations: self-deposited Inverse Floaters	$ 191,075,000	$ 16,275,000	$ 434,051,000	$ 21,923,000	$ 144,090,000
Floating rate obligations: externally-deposited Inverse Floaters	71,775,000	11,095,000	76,510,000	—	—
Total	$ 262,850,000	$ 27,370,000	$ 510,561,000	$ 21,923,000	$ 144,090,000

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

Self-Deposited Inverse Floaters	NVG	NZF	NMZ	NMCO	NDMO
Average floating rate obligations outstanding	$ 191,403,470	$ 16,897,117	$ 415,544,743	$ 24,500,046	$ 6,441,995
Average annual interest rate and fees	1.29 %	1.37 %	1.33 %	1.74 %	0.75 %

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 is 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.

174

Table of Contents

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 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. 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.

As of the end of the reporting period, each Fund’s maximum exposure to the Floaters issued by Recourse Trusts for self-deposited Inverse Floaters and externally-deposited Inverse Floaters was as follows:

Floating Rate Obligations – Recourse Trusts	NVG	NZF	NMZ	NMCO	NDMO
Maximum exposure to Recourse Trusts: self-deposited Inverse Floaters	$ 183,330,000.00	$ 8,775,000	$ 409,271,000	$ 21,923,000	$ 144,090,000
Maximum exposure to Recourse Trusts: externally-deposited Inverse Floaters	59,420,000	9,420,000	76,510,000	—	—
Total	$ 242,750,000	$ 18,195,000	$ 485,781,000	$ 21,923,000	$ 144,090,000

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.

Investment Transactions

Long-term purchases and sales (including maturities) during the current fiscal period were as follows:

	NVG	NZF	NMZ	NMCO	NDMO
Purchases	$ 873,349,609	$ 748,232,607	$ 434,829,616	$ 1,214,878,901	$ 919,671,478
Sales and maturities	854,486,379	749,365,978	159,702,130	726,832,297	20,638,670

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

Investments in Derivatives

In addition to the inverse floating rate securities in which each Fund may invest, which are considered portfolio securities for financial reporting purposes, each Fund is authorized to invest in certain other derivative instruments such as futures, options and swap contracts. Each Fund limits its investments in futures, options on futures and swap contracts to the extent necessary for the Adviser to claim the exclusion from registration by the Commodity Futures Trading Commission as a commodity pool operator with respect to the Fund. The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds’ investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.

Although the Funds are authorized to invest in derivative instruments, and may do so in the future, they did not make any such investments during the current fiscal period.

Market and Counterparty Credit Risk

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

175

Table of Contents

Notes to Financial Statements (continued)

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.

Fund Shares

Common Shares

Common Shares Equity Shelf Programs and Offering Costs

NMZ has filed a registration statement with the Securities and Exchange Commission (“SEC”) authorizing the Fund to issue additional common shares through one or more equity shelf programs (“Shelf Offering”), which became effective with the SEC during a prior fiscal period.

Under this Shelf Offering, the Fund, 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 the 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.

Additional authorized common shares, common shares sold and offering proceeds, net of offering costs under the Fund’s Shelf Offering during the Fund’s current and prior fiscal period were as follows:

	NMZ — Year	Year
	Ended	Ended
	10/31/20	10/31/19
Additional authorized common shares	19,500,000	15,700,000*
Common shares sold	13,935,297	4,928,383
Offering proceeds, net of offering costs	$192,765,554	$69,515,572

Represents additional authorized common shares for the period April 11, 2019 through October 31, 2019.

Costs incurred by the Fund in connection with its initial shelf registration are recorded as a prepaid expense and recognized as “Deferred offering costs” on the Statement of Assets and Liabilities. These costs are amortized pro rata as common shares are sold and are recognized as a component of “Proceeds from shelf offering, net of offering costs” on the Statement of Changes in Net Assets. Any deferred offering costs remaining one year after effectiveness of the initial shelf registration will be expensed. Costs incurred by the Funds to keep the shelf registration current are expensed as incurred and recognized as a component of “Other expenses” on the Statement of Operations.

Common Share Transactions

Preferred Shares

Adjustable Rate MuniFund Term Preferred Shares

The following Funds have issued and have 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.

The details of each Fund’s AMTP Shares outstanding as of the end of the reporting period, were as follows:

				Liquidation
				Preference,
		Shares	Liquidation	Net of Deferred
Fund	Series	Outstanding	Preference	Offering Costs
NVG	2028*	1,120	$112,000,000	$111,913,155
NMZ	2028	870	$87,000,000	$86,882,357

AMTP Shares issued in connection with the Merger.

Each 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 Funds may be obligated to redeem a certain amount of the AMTP Shares if the Funds 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 each Fund’s AMTP Shares are as follows:

Fund	Notice — Period	Series	Term — Redemption Date	Premium — Expiration Date
NVG	540-day	2028	December 1, 2028**	February 13, 2019
NMZ	360-day	2028	March 1, 2028**	August 31, 2018

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

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

	NVG***	NMZ
Average liquidation preference of AMTP Shares outstanding	$112,000,000	$87,000,000
Annualized dividend rate	1.55%	1.59%

*** For the period November 18, 2019 (Merger date) through October 31, 2020.

177

Table of Contents

Notes to Financial Statements (continued)

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 Funds’ 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 “Adjustable Rate MuniFund Term Preferred (“AMTP”) Shares, net of deferred offering costs” 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 “Interest payable” 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 each 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 “Adjustable Rate MuniFund Term Preferred (“AMTP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities and “Interest expense and amortization of offering costs” on the Statement of Operations.

MuniFund Preferred Shares

The following Funds have issued and have outstanding MuniFund Preferred (“MFP”) Shares, with a $100,000 ($1,000 for NVG’s Series B) liquidation preference per share. These MFP Shares were issued via private placement and are not publically 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 Fund 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, the market value of the MFP Shares is expected to approximate its liquidation preference. Shareholders have the ability to request a best-efforts tender of their 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 unsuccess- ful 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 enables its shareholders to require a liquidity provider, with 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 of Operations.

For financial reporting purposes, the liquidation preference of MFP Shares is recorded as a liability and is recognized as a component of “MuniFund Preferred (“MFP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities. Dividends on the MFP shares are treated as interest payments for financial reporting purposes. Unpaid dividends on MFP shares are recognized as a component on “Interest payable” on the Statement of Assets and Liabilities. Dividends accrued on MFP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

178

Table of Contents

Subject to certain conditions, MFP Shares may be redeemed, in whole or in part, at any time at the option of the Fund. The Fund may also be required to redeem certain MFP 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 in all circumstances is equal to the liquidation preference per share plus any accumulated but unpaid dividends.

NMCO incurred offering costs of $1,234,219 in connection with its offering of MFP Shares, which were recorded as a deferred charge and are being amortized over the life of the shares. These offering costs are recognized as a component of “MuniFund Preferred (“MFP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities and “Interest expense and amortization of offering costs” on the Statement of Operations.

As of the end of the reporting period, NVG, NZF and NMCO had $403,997,740, $640,010,468 and $448,842,816 of MFP Shares at liquidation preference, net of deferred offering costs, respectively. Further details of each Fund’s MFP Shares outstanding as of the end of the reporting period, were as follows:

Variable Rate Demand Preferred Shares

The following Funds have issued and have outstanding Variable Rate Demand Preferred (“VRDP”) Shares, with a $100,000 liquidation preference per share. VRDP Shares are issued via private placement and are not publicly available.

As of the end of the reporting period, NVG and NZF had $1,408,052,524 and $722,526,702 of VRDP Shares at liquidation preference, net of deferred offering costs, respectively. Further details of the Funds’ VRDP Shares outstanding as of the end of the reporting period, were as follows:

Fund	Series	Shares — Outstanding	Remarketing — Fees*	Liquidation — Preference	Maturity
NVG	1	1,790	0.10%	$179,000,000	December 1, 2043

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

N/A 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 the 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.

Table of Contents

Notes to Financial Statements (continued)

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 a 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:

	NVG	NZF
Average liquidation preference of VRDP Shares outstanding	$1,411,600,000	$727,000,000
Annualized dividend rate	0.83%	1.38%

For financial reporting purposes, the liquidation preference of VRDP Shares is a liability and is recognized as a component of “Variable Rate Demand Preferred (“VRDP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities. Unpaid dividends on VRDP Shares are recognized as a component of “Interest payable” 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 a deferred charge, which are amortized over the life of the shares and are recognized as a component of “Variable Rate Demand Preferred (“VRDP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities and “Interest expense and amortization of offerings costs” on the Statement of Operations. In addition to interest expense, each Fund also pays a per annum liquidity fee to the liquidity provider, as well as a remarketing fee, which are recognized as “Liquidity fees” and “Remarketing fees,” respectively, on the Statement of Operations.

Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income tax, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.

For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the NAVs of the Funds.

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

	NVG	NZF	NMZ	NMCO	NDMO
Tax cost of investments	$4,972,676,377	$3,302,664,674	$1,144,332,602	$1,146,754,347	$754,073,261
Gross unrealized:
Appreciation	515,002,769	345,214,201	89,927,840	28,469,197	3,439,771
Depreciation	(36,875,488)	(53,592,476)	(75,837,644)	(77,264,431)	(4,696,239)
Net unrealized appreciation (depreciation) of investments	$ 478,127,281	$ 291,621,725	$ 14,090,196	$ (48,795,234)	$ (1,256,468)

Permanent differences, primarily due to federal taxes paid, nondeductible offering costs, taxable market discount, nondeductible reorganization expenses, reorganization adjustments, paydowns, and treatment of notional principal contracts, resulted in reclassifications among the Funds’ components of common share net assets as of October 31, 2020, the Funds’ tax year end.

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

	NVG	NZF	NMZ	NMCO	NDMO
Undistributed net tax-exempt income 1	$ 7,215,271	$5,518,539	$10,923,431	$3,254,558	$1,447,380
Undistributed net ordinary income 2	2,620,185	891,633	1,999,315	364,252	41,844
Undistributed net long-term capital gains	20,803,556	—	—	—	—

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

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

Management Fees and Other Transactions with Affiliates

Management Fees

Each Fund’s management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Sub-Adviser is compensated for its services to the 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 Fund 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 schedules:

	NVG
	NZF
Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million	0.5000%
For the next $125 million	0.4875
For the next $250 million	0.4750
For the next $500 million	0.4625
For the next $1 billion	0.4500
For the next $3 billion	0.4250
For managed assets over $5 billion	0.4125

	NMZ
Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million	0.5500%
For the next $125 million	0.5375
For the next $250 million	0.5250
For the next $500 million	0.5125
For the next $1 billion	0.5000
For the next $3 billion	0.4750
For managed assets over $5 billion	0.4625

	NMCO
Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million	0.7500%
For the next $125 million	0.7375
For the next $250 million	0.7250
For the next $500 million	0.7125
For the next $1 billion	0.7000
For the next $3 billion	0.6750
For managed assets over $5 billion	0.6625

	NDMO
Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million	0.7000%
For the next $125 million	0.6875
For the next $250 million	0.6750
For the next $500 million	0.6625
For the next $1 billion	0.6500
For the next $3 billion	0.6250
For managed assets over $5 billion	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 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 Nuveen funds that were reorganized into funds advised by an affiliate of the Adviser during the 2019 calendar year. As of October 31, 2020, the complex-level fee for each Fund was 0.1572%.

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 following Funds engaged in cross-trades pursuant to these procedures as follows:

Cross-Trades	NVG	NZF	NMZ	NMCO
Purchases	$31,100,000	$30,995,280	$65,049,238	$ 89,145,588
Sales	65,400,000	58,930,316	—	114,648,724

Borrowing Arrangements

Committed Line of Credit

NVG, NZF, NMZ and NMCO, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, $2.405 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for various purposes other than leveraging for investment purposes. Each Participating Fund is allocated a designated proportion of the facility’s capacity (and its associated costs, as described below) based upon a multi-factor assessment of the likelihood and frequency of its need to draw on the facility, the size of the Fund and its anticipated

183

Notes to Financial Statements (continued)

draws, and the potential importance of such draws to the operations and well-being of the Fund, relative to those of the other Funds. A Fund may effect draws on the facility in excess of its designated capacity if and to the extent that other Participating Funds have undrawn capacity. The credit facility expires in June 2021 unless extended or renewed.

The credit facility has the following terms: a 0.10% upfront fee, 0.15% per annum on unused commitment amounts and a drawn interest rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.25% (1.00% prior to June 24, 2020) per annum or (b) the Fed Funds rate plus 1.25% (1.00% prior to June 24, 2020) per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Other expenses” on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund.

During the current fiscal period, the following Funds utilized this facility. Each Fund’s maximum outstanding balance during the utilization period was as follows:

	NVG	NZF	NMZ
Maximum outstanding balance	$75,100,000	$52,200,000	$23,200,000

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

	NVG	NZF	NMZ
Utilization period (days outstanding)	30	65	1
Average daily balance outstanding	$23,020,000	$14,267,901	$23,200,000
Average annual interest rate	2.75%	2.54%	1.86%

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.

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.

Fund Merger

The Merger as previously described in Note 1 — General Information was structured to qualify as a tax-free merger under the Internal Revenue Code for federal income tax purposes, and the Target Fund’s shareholders recognized no gain or loss for federal income tax purposes as a result. Prior to the closing of the Merger, the Target Fund distributed all of its net investment income and capital gains, if any. Such a distribution may be taxable to the Target Fund’s 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 Fund as of the date of the Merger, were as follows:

	NTC
Cost of investments	$278,923,665
Fair value of investments	294,696,476
Net unrealized appreciation (depreciation) of investments	15,772,811

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 Fund 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 the Merger were as follows:

Target Fund – Prior to Merger	NTC
Common shares outstanding	14,328,976
Net assets applicable to common shares	$184,807,196
NAV per common share outstanding	$ 12.90
Acquiring Fund – Prior to Merger	NVG
Common shares outstanding	202,552,895
Net assets applicable to common shares	$3,460,366,031
NAV per common share outstanding	$ 17.08
Acquiring Fund – Post Merger	NVG
Common shares outstanding	213,370,544
Net assets applicable to common shares	$3,645,173,227
NAV per common share outstanding	$ 17.08

Pro Forma Results of Operations (Unaudited)

The beginning of the Target Fund’s current fiscal period was June 1, 2019. Assuming the Merger had been completed on November 1, 2019, the beginning of the Acquiring Fund’s current fiscal period, the pro forma results of operations for the current fiscal period, are as follows:

Acquiring Fund – Pro Forma Results from Operations	NVG
Net investment income (loss)	$174,822,720
Net realized and unrealized gains (losses)	(83,738,038)
Change in net assets resulting from operations	91,084,682

Because the combined investment portfolios of the Acquiring Fund have been managed as a single integrated portfolio since the Merger was completed, it is not practicable to separate the amounts of revenue and earnings of the Target Fund that have been included in the Statement of Operations of the Acquiring Fund since the Merger was consummated.

Cost and Expenses

In connection with the 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 “Merger expenses” on the Statement of Operations.

Subsequent Events Committed Line of Credit

During November 2020, NDMO entered into a $215 million committed line of credit (“Borrowings”) agreement with its custodian bank, as a means of leverage. The credit agreement expires in November 2021 unless extended or renewed.

Interest is charged on the Borrowings drawn amount for a Base Rate Loan at a rate per annum equal to the higher of (a) one-month LIBOR rate plus 0.75% or (b) the Federal Funds Rate plus 0.85% or for a LIBOR Loan at a rate per annum equal to the LIBOR Offered Rate plus 0.75%. NDMO also accrues a 0.15% per annum commitment fee on the undrawn balance based on the maximum commitment amount of the Borrowings to the extent the unused portion of the Borrowings is less than 25% of the maximum commitment amount, otherwise the per annum commitment fee is 0.25%. NDMO also incurred a 0.05% upfront fee.

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

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 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.

The Fund generally invests in municipal securities with long-term maturities in order to maintain an average effective maturity of 15 to 30 years, including the effects of leverage, but the average effective maturity of obligations held by the Fund may be lengthened or shortened as a result of portfolio transactions effected by the Fund’s investment adviser and/or the Fund’s sub-adviser, depending on market conditions and on an assessment by the portfolio manager of which segments of the municipal securities markets offer the most favorable relative investment values and opportunities for tax-exempt income and total return.

“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.

Approving Changes in Investment Policies

The Board of Trustees of the Fund may change a policy 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.

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.

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 “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 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 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 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.

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 fixed-income securities or as a substitute for a position in the underlying asset. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments.

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.

NUVEEN MUNICIPAL CREDIT INCOME FUND (NZF)

Investment Objectives

The Fund’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 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 non-fundamental policy, under normal circumstances, the Fund may invest up to 55% of its Managed Assets (as defined below) in securities that, at the time of investment, are rated below the three highest grades (Baa or BBB or lower) by at least one NRSRO or are unrated but judged to be of comparable quality by the Fund’s sub-adviser.

Table of Contents

Under normal circumstances:

• The Fund may invest up to 20% of its Managed Assets in municipal securities that pay interest that is taxable under the federal alternative minimum tax.

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

Approving Changes in Investment Policies

The Board of Trustees of the Fund may change a policy 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, 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.

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.

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. 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.

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 in municipal securities of any credit quality and without limit in below investment grade municipal securities (municipal securities rated BB+/Ba1 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 up to 20% of its Managed Assets in taxable debt obligations, including taxable municipal 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 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 fixed-income 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.

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.

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. Municipal securities of below investment grade quality are regarded as having speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal, and may be subject to higher price volatility and default risk than investment grade municipal securities of comparable terms and duration. Issuers of lower grade municipal securities may be highly leveraged and may not have available to them more traditional methods of financing. The prices of these lower grade securities 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 municipal securities may not be as liquid as the secondary market for more highly rated municipal securities, a factor which may have an adverse effect on the Fund’s ability to dispose of a particular municipal security. If a below investment grade municipal 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.

Defaulted and Distressed Securities Risk. The Fund may invest in securities of an issuer that is in default or that is in bankruptcy or insolvency proceedings at the time of purchase. In addition, the Fund may hold investments that at the time of purchase are not in default or involved in bankruptcy or insolvency proceedings, but may later become so. Moreover, the Fund may invest in low-rated securities that, 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. Defaulted or distressed securities may be subject to restrictions on resale.

197

Table of Contents

Shareholder Update (Unaudited) (continued)

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.

It is possible that developments in the derivatives market, including changes in government regulation, could adversely impact the Fund’s ability to invest in certain derivatives.

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.

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 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. As concentration 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 the sectors noted above, 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 and may include restricted securities, which are securities that may not be resold unless they have been registered under the 1933 Act or that can be sold in a private transaction pursuant to an available exemption from such registration. Illiquid investments involve the risk that the investments will not be able to be sold at the time desired by the Fund or at prices approximating the value at which the Fund is carrying the investments on its books from time to time.

198

Table of Contents

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.

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.

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

199

Table of Contents

Shareholder Update (Unaudited) (continued)

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.

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.

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.

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

200

Table of Contents

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.

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.

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. 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.

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

201

Table of Contents

Shareholder Update (Unaudited) (continued)

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.

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 securities 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, events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may adversely affect the global economy and the markets and issuers in which the Fund invests. Recent examples of such events include 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. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a significant impact on the economy. These events could also impair the information technology and other operational systems upon which the Fund’s service providers, including the investment adviser and 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. 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.

The SEC recently adopted rules governing the use of derivatives by registered investment companies, which could affect the nature and extent of derivatives used by the Fund. The full impact of such rules is uncertain at this time. It is possible that such rules, as interpreted, applied and enforced by the SEC, could limit the implementation of the Fund’s use of derivatives, which could have an adverse impact on the Fund.

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 and 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.

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

202

Table of Contents

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.

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. In response to the financial crisis and recent market events, policy and legislative changes by the United States government and the Federal Reserve to assist in the ongoing support of financial markets, both domestically and in other countries, are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. Withdrawal of government support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding, could adversely impact the value and liquidity of certain securities. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations, including changes in tax laws and the imposition of trade barriers. The impact of new financial regulation legislation on the markets and the practical implications for market participants may not be fully known for some time. Changes to the Federal Reserve policy may affect the value, volatility and liquidity of dividend and interest paying securities. In addition, the contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

203

Table of Contents

Shareholder Update (Unaudited) (continued)

Interest rates have been unusually low in recent years in the United States and abroad but there is consensus that interest rates will increase during the life of the Fund, which could negatively impact the price of debt securities. Because there is little precedent for this situation, it is difficult to predict the impact of a significant rate increase on various markets.

The current political climate has intensified concerns about a potential trade war between China and the United States, as each country has recently imposed tariffs on the other country’s products. 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.

The impact of these developments in the near- and long-term is unknown and could have additional adverse effects on economies, financial markets and asset valuations around the world.

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, 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, 2020 as a percentage of Managed Assets (including assets attributable to such leverage), (ii) the estimated annual effective interest expense rate payable by the Fund on such instruments (based on actual leverage costs incurred during the fiscal year ended October 31, 2020) 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 other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, such as 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 Fund. Your actual returns may be greater or less than those appearing below.

Table of Contents

Common Share total return is composed of two elements — the distributions paid by a 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 a Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, a 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 a 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 a 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, a Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors.

DIVIDEND REINVESTMENT PLAN

Nuveen Closed-End Funds Automatic Reinvestment Plan

Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares. By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.

Easy and convenient

To make recordkeeping easy and convenient, each month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.

How shares are purchased

The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above 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.

Shareholder Update (Unaudited) (continued)

Amended and Restated By-Laws

On October 5, 2020, after a rigorous and deliberative review, and consistent with the interests of 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 Municipal Opportunities Fund (each a “Fund” and collectively the “Funds”) long-term shareholders, the Board of Trustees of each Fund adopted Amended and Restated By-Laws.

Among other changes, the Amended and Restated By-Laws require compliance with certain amended deadlines and procedural and informational requirements in connection with advance notice of shareholder proposals or nominations, including certain information about the proponent and the proposal, or in the case of a nomination, the nominee. Any shareholder considering making a nomination or other proposal should carefully review and comply with those provisions of the Amended and Restated By-Laws.

The Amended and Restated By-Laws also include provisions (the “Control Share By-Law”) pursuant to which, in summary, a shareholder who obtains beneficial ownership of common shares of a Fund in a “Control Share Acquisition” may exercise voting rights with respect to such shares only to the extent the authorization of such voting rights is approved by other shareholders of the Fund. The Control Share By-Law is primarily intended to protect the interests of the Fund and its long-term shareholders by limiting the risk that the Fund will become subject to undue influence by opportunistic traders pursuing short-term agendas adverse to the best interests of the Fund and its long-term shareholders. The Control Share By-Law does not eliminate voting rights for common shares acquired in Control Share Acquisitions, but rather entrusts the Fund’s other “non-interested” shareholders with determining whether to approve the authorization of the voting rights of the person acquiring such shares.

Subject to various conditions and exceptions, the Control Share By-Law defines a “Control Share Acquisition” to include an acquisition of common shares that, but for the Control Share By-Law, would give the beneficial owner, upon the acquisition of such shares, the ability to exercise voting power in the election of Trustees of a Fund in any of the following ranges:

(i) one-tenth or more, but less than one-fifth of all voting power;

(ii) one-fifth or more, but less than one-third of all voting power;

(iii) one-third or more, but less than a majority of all voting power; or

(iv) a majority or more of all voting power.

The Control Share By-Law generally excludes certain acquisitions of common shares from the definition of a Control Share Acquisition, including acquisitions of common shares that occurred prior to October 5, 2020, though such shares are included in assessing whether any subsequent share acquisition exceeds one of the enumerated thresholds.

Subject to certain conditions and procedural requirements set forth in the Control Share By-Law, including the delivery of a “Control Share Acquisition Statement” to the Funds’ Secretary setting forth certain required information, a shareholder who obtains or proposes to obtain beneficial ownership of common shares in a Control Share Acquisition generally may demand a special meeting of shareholders for the purpose of considering whether the voting rights of such acquiring person with respect to such shares shall be authorized.

This discussion is only a high-level summary of certain aspects of the Amended and Restated By-Laws, and is qualified in its entirety by reference to the Amended and Restated By-Laws. Shareholders should refer to the Amended and Restated By-Laws for more information. A copy of the Amended and Restated By-Laws can be found in the Current Report on Form 8-K filed by the Funds with the Securities and Exchange Commission on October 6, 2020, which is available at www.sec.gov, and may also be obtained by writing to the Secretary of the Funds at 333 West Wacker Drive, Chicago, Illinois 60606.

Glossary of Terms Used in this Report Anchor (Unaudited)

■ Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.

■ Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond fund’s value to changes when market interest rates change. Generally, the longer a bond’s or fund’s duration, the more the price of the bond or fund will change as interest rates change.

■ Effective Leverage: Effective leverage is a fund’s effective economic leverage, and includes both regulatory leverage (see leverage) and the leverage effects of certain derivative investments in 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, also known as inverse floaters or tender option bonds (TOBs), are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.

■ Leverage: Leverage is created whenever a fund has investment exposure (both reward and/or risk) equivalent to more than 100% of the investment capital.

■ NVG and NZF Custom Blended Fund Performance Benchmark: The Fund Performance Benchmark is an unleveraged index consisting of the returns of the S&P Municipal Bond Index prior to 4/11/16 and thereafter the returns of an 60%/40% blend of the S&P Municipal Bond Investment Grade Index and the S&P Municipal Bond High Yield Index, respectively. The S&P Municipal Bond Index is an unmanaged, market value-weighted index designed to measure the performance of tax-exempt municipal bonds. The S&P Municipal Bond Investment Grade Index is an unmanaged, market value-weighted index designed to measure the performance of tax-exempt municipal bonds rated investment grade by Standard & Poor’s, Moody’s and/or Fitch. The S&P Municipal Bond High Yield Index is an unmanaged, market value-weighted index designed to measure the performance of the tax-exempt, high yield municipal bonds. Index returns assume compounding and do not include the effects of any fees or expenses.

208

Table of Contents

■ Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund’s Net Assets divided by its number of shares outstanding.

■ Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.

■ 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.

■ S&P Municipal Bond High Yield Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment grade U.S. high yield municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

■ S&P Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment-grade U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

■ S&P Municipal Yield Index: An unleveraged, market value-weighted index containing all bonds in the S&P Municipal Bond Index that are non-rated bonds or whose ratings are BB+ by S&P and BA-1 by Moody’s Investors Service, Inc. or lower. This index does not contain bonds that are pre-refunded or escrowed to maturity. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

■ Total Investment Exposure: Total investment exposure is a fund’s assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a fund’s use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.

■ Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

Annual Investment Management Anchor Agreement Approval Process (Unaudited)

The Approval Process

The Boards of Trustees (collectively, the “ Board ” and each Trustee, a “ Board Member ”) of the Funds, including the Board Members who are not “interested persons” (as defined under the Investment Company Act of 1940 (the “ 1940 Act ”)) (the “ Independent Board Members ”), are responsible for determining whether to initially approve or, after an initial term, to renew, the advisory arrangements of their respective Funds. A discussion of the Board’s most recent approval of the renewal of the advisory arrangements for Nuveen AMT-Free Municipal Credit Income Fund (the “ AMT-Free Municipal Credit Income Fund ”), Nuveen Municipal Credit Income Fund (the “ Municipal Credit Income Fund ”), and Nuveen Municipal High Income Opportunity Fund (the “ Municipal High Income Opportunity Fund ”) is set forth in Part I below. The advisory arrangements for Nuveen Municipal Credit Opportunities Fund (the “ Municipal Credit Opportunities Fund ”) and Nuveen Dynamic Municipal Opportunities Fund (the “ Dynamic Municipal Opportunities Fund ”) have not yet been up for renewal. A discussion of the Board’s initial approval of the advisory arrangements for the Municipal Credit Opportunities Fund is set forth in such Fund’s annual report for the period ended October 31, 2019. A discussion of the Board’s initial approval of the advisory arrangements for the Dynamic Municipal Opportunities Fund is set forth in Part II below.

PART I

Nuveen AMT-Free Municipal Credit Income Fund Nuveen Municipal Credit Income Fund Nuveen Municipal High Income Opportunity Fund

At a meeting held on May 19-21, 2020 (the “ May Meeting ”), the Board (which is comprised entirely of Independent Board Members) approved, for its respective Fund (as defined below), the renewal of the management agreement (for purposes of this Part I, each, an “ Investment Management Agreement ”) with Nuveen Fund Advisors, LLC (the “ Adviser ”) pursuant to which the Adviser serves as investment adviser to such Fund and the sub-advisory agreement (for purposes of this Part I, each, a “ Sub-Advisory Agreement ”) with Nuveen Asset Management, LLC (the “ Sub-Adviser ”) pursuant to which the Sub-Adviser serves as the investment sub-adviser to such Fund. For purposes of this Part I, the AMT-Free Municipal Credit Income Fund, Municipal Credit Income Fund and Municipal High Income Opportunity Fund are the “ Funds ” and each, a “ Fund. ” Although the 1940 Act requires that continuances of the Advisory Agreements (as defined below) be approved by the in-person vote of a majority of the Independent Board Members, the May Meeting was held virtually through the internet in view of the health risks associated with holding an in-person meeting during the COVID-19 pandemic and governmental restrictions on gatherings. The May Meeting was held in reliance on an order issued by the Securities and Exchange Commission on March 13, 2020, as extended on March 25, 2020, which provided registered investment companies temporary relief from the in-person voting requirements of the 1940 Act with respect to the approval of a fund’s advisory agreement in response to the challenges arising in connection with the COVID-19 pandemic.

Following up to an initial two-year period, the Board considers the renewal of each Investment Management Agreement and Sub-Advisory Agreement on behalf of the applicable Fund on an annual basis. For purposes of this Part I, the Investment Management Agreements and Sub-Advisory Agreements are collectively referred to as the “ Advisory Agreements ” and the Adviser and the Sub-Adviser are collectively, the “ Fund Advisers ” and each, a “ Fund Adviser. ” Throughout the year, the Board and its committees meet regularly and, at these meetings, review an extensive array of topics and information that are relevant to its annual consideration of the renewal of the advisory agreements for the Nuveen funds. Such information may address, among other things, fund performance; the Adviser’s strategic plans; the review of the funds and investment teams; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers to the funds; valuation of securities; fund expenses; overall market and regulatory developments; the management of leverage financing; and the secondary market trading of the closed-end funds and any actions to address discounts.

Table of Contents

In addition to the information and materials received during the year, the Board, in response to a request made on its behalf by independent legal counsel, received extensive materials and information prepared specifically for its annual consideration of the renewal of the advisory agreements for the Nuveen funds by the Adviser and by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials cover a wide range of topics including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of each sub-adviser to the Nuveen funds and the applicable investment teams; an analysis of fund performance in absolute terms and as compared to the performance of certain peer funds and benchmarks with a focus on any performance outliers; an analysis of the fees and expense ratios of the Nuveen funds in absolute terms and as compared to those of certain peer funds with a focus on any expense outliers; a description of portfolio manager compensation; a review of the secondary market trading of shares of the Nuveen closed-end funds (including, among other things, an analysis of performance, distribution and valuation and capital raising trends in the broader closed-end fund market and in particular with respect to Nuveen closed-end funds; a review of the leverage management actions taken on behalf of the Nuveen closed-end funds and their resulting impact on performance; and a description of the distribution management process and any capital management activities); a review of the performance of various service providers; a description of various initiatives Nuveen had undertaken or continued during the year for the benefit of particular fund(s) and/or the complex; a description of the profitability or financial data of Nuveen and the sub-advisers to the Nuveen funds; and a description of indirect benefits received by the Adviser and the sub-advisers as a result of their relationships with the Nuveen funds.

In continuing its practice, the Board met prior to the May Meeting to begin its considerations of the renewal of the Advisory Agreements. Accordingly, on April 27-28, 2020 (the “ April Meeting ”), the Board met to review and discuss, in part, the performance of the Nuveen funds and the Adviser’s evaluation of each sub-adviser to the Nuveen funds. In its review, the Board recognized the volatile market conditions occurring during the first half of 2020 arising, in part, from the public health crisis caused by the novel coronavirus known as COVID-19 and the resulting impact on fund performance. Accordingly, the Board reviewed, among other things, fund performance reflecting the more volatile periods, including for various time periods ended the first quarter of 2020 and for various time periods ended April 17, 2020. At the April Meeting, the Board Members asked questions and requested additional information that was provided for the May Meeting. In continuing its review of the Nuveen funds in light of the extraordinary market conditions experienced in early 2020, the Board received updated fund performance data reflecting various time periods ended May 8, 2020 for its May Meeting. The Board also continued its practice of seeking to meet periodically with the various sub-advisers to the Nuveen funds and their investment teams, when feasible.

The Independent Board Members considered the review of the advisory agreements for the Nuveen funds to be an ongoing process and employed the accumulated information, knowledge, and experience the Board Members had gained during their tenure on the boards governing the Nuveen funds and working with the Adviser and sub-advisers in their review of the advisory agreements. The contractual arrangements are a result of multiple years of review, negotiation and information provided in connection with the boards’ annual review of the Nuveen funds’ advisory arrangements and oversight of the Nuveen funds.

The Independent Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives from the Adviser or the Sub-Adviser were present. In connection with their annual review, the Independent Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements.

The Board’s decision to renew the Advisory Agreements was not based on a single identified factor, but rather the decision reflected the comprehensive consideration of all the information provided throughout the year and at the April and May Meetings, and each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the approval process. The following summarizes the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements and its conclusions.

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 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.

With respect to the Adviser, the Board recognized that the Adviser has provided a vast array of services the scope of which has expanded over the years in light of regulatory, market and other developments, such as the development of expanded compliance programs for the Nuveen funds. The Board also noted the extensive resources, tools and capabilities the Adviser and its affiliates devoted to the various operations of the Nuveen funds. These services include, but are not limited to: investment oversight, risk management and securities valuation services (such as analyzing investment performance and risk data; overseeing and reviewing the various sub-advisers to the Nuveen funds and their investment teams; overseeing trade execution, soft dollar practices and securities lending activities; providing daily valuation services and developing related valuation policies, procedures and methodologies; overseeing risk disclosure; periodic testing of investment and liquidity risks; participating in financial statement and marketing disclosures; participating in product development; and participating in leverage management and liquidity monitoring); product management (such as analyzing a fund’s position in the marketplace, setting dividends, preparing shareholder and intermediary communications and other due diligence support); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the funds’ independent public accountants and other service providers; managing fund budgets and expenses; and helping to fulfill the funds’ regulatory filing requirements); oversight of shareholder services and transfer agency functions (such as overseeing transfer agent service providers which include registered shareholder customer service and transaction processing; and overseeing proxy solicitation and tabulation services); Board relations services (such as organizing and administering Board and committee meetings, preparing various reports to the Board and committees and providing other support services); compliance and regulatory oversight services (such as devising compliance programs; managing compliance policies; monitoring compliance with applicable fund policies and laws and regulations; and evaluating the compliance programs of the various sub-advisers to the Nuveen funds and certain other service providers); legal support and oversight of outside law firms (such as helping to prepare and file registration statements and proxy statements; overseeing fund activities and providing legal interpretations regarding such activities; and negotiating agreements with other fund service providers); and providing leverage, capital and distribution management services.

The Board also recognized that the Adviser and its affiliates have undertaken a number of initiatives over the previous year that benefited the complex and/or particular Nuveen funds including, but not limited to:

• Fund Improvements and Product Management Initiatives – continuing to proactively manage the Nuveen fund complex as a whole and at the individual fund level with an aim to enhance the shareholder outcomes through, among other things, rationalizing the product line and gaining efficiencies through mergers, repositionings and liquidations; reviewing and updating investment policies and benchmarks; and integrating certain investment teams and changing the portfolio managers serving various funds;

• Capital Initiatives – continuing to invest capital to support new Nuveen funds with initial capital as well as to facilitate modifications to the strategies or structure of existing funds;

• Compliance Program Initiatives – continuing efforts to mitigate compliance risk, increase operating efficiencies, strengthen key compliance program elements and support international business growth and other objectives through, among other things, integrating various investment teams across affiliates, consolidating marketing review functions, enhancing compliance related technologies and establishing and maintaining shared broad-based compliance policies throughout the organization and its affiliates;

212

Table of Contents

• Risk Management and Valuation Services - continuing efforts to provide Nuveen with a more disciplined and consistent approach to identifying and mitigating the firm’s operational risks through, among other things, enhancing the interaction and reporting between the investment risk management team and various affiliates and adopting a risk operational framework across the complex;

• Regulatory Matters – continuing efforts to monitor regulatory trends and advocate on behalf of the Nuveen funds, to implement and comply with new or revised rules and mandates and to respond to regulatory inquiries and exams;

• Government Relations – continuing efforts of various Nuveen teams and affiliates to develop policy positions on a broad range of issues that may impact the Nuveen funds, advocate and communicate these positions to lawmakers and other regulatory authorities and work with trade associations to ensure these positions are represented;

• Business Continuity, Disaster Recovery and Information Services – continuing to periodically test business continuity and disaster recovery plans, maintain an information security program designed to identify and manage information security risks, and provide reports to the Board, at least annually, addressing, among other things, management’s security risk assessment, cyber risk profile, potential impact of new or revised laws and regulations, incident tracking and other relevant information technology risk-related reports;

• Expanded Dividend Management Services – continuing to manage the dividends among the varying types of Nuveen funds within the Nuveen complex to be consistent with the respective fund’s product design and investing resources to develop systems to assist in the process for newer products such as target term funds; and

• with respect specifically to closed-end funds, such initiatives also included:

•• Leverage Management Services – continuing to actively manage leverage including developing new leverage instruments, managing leverage exposure and costs through various providers, and managing and adapting tender option bond structures to comply with regulations and developing further relationships with leverage providers;

•• Capital Management, Market Intelligence and Secondary Market Services – ongoing capital management efforts through shelf offerings, share repurchases as appropriate to address discounts, tender offers and capital return programs as well as providing market data analysis to help understand closed-end fund ownership cycles and their impact on secondary market trading as well as to improve proxy solicitation efforts; and

•• Closed-end Fund Investor Relations Program – maintaining the closed-end fund investor relations program which, among other things, raises awareness, provides educational materials and cultivates advocacy for closed-end funds and the Nuveen closed-end fund product line.

The Board also noted the benefits to shareholders of investing in a Nuveen fund, as each Nuveen fund is a part of a large fund complex with a variety of investment disciplines, capabilities, expertise and resources available to navigate and support the funds including during stressed times as occurred in the market in the first half of 2020. In addition to the services provided by the Adviser, the Board also considered the risks borne by the Adviser and its affiliates in managing the Nuveen funds, including entrepreneurial, operational, reputational, regulatory and litigation risks.

The Board further considered the division of responsibilities between the Adviser and the Sub-Adviser and recognized that the Sub-Adviser and its investment personnel generally are responsible for the management of 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 Sub-Adviser’s assets under management and changes thereto, a summary of the applicable investment team and changes thereto, the investment approach of the team and the performance of the funds sub-advised by the Sub-Adviser over various periods. The Board further considered at the May Meeting or prior meetings evaluations of the Sub-Adviser’s compliance program and trade execution. The Board also considered the structure of investment personnel

213

compensation programs and whether this structure provides appropriate incentives to act in the best interests of the respective Nuveen funds. The Board noted that the Adviser recommended the renewal of the Sub-Advisory Agreements.

Based on its review, the Board determined, in the exercise of its reasonable business judgment, that it was satisfied with the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement.

B. The Investment Performance of the Funds and Fund Advisers

In evaluating the quality of the services provided by the Fund Advisers, the Board also received and considered a variety of investment performance data of the Nuveen funds they advise. In this regard, the Board reviewed, among other things, Fund performance over the quarter, one-, three- and five-year periods ending December 31, 2019. Unless otherwise indicated, the performance data referenced below reflects the periods ended December 31, 2019. In general, the year 2019 was a period of strong market performance. However, as noted above, the Board recognized the unprecedented market volatility and decline that occurred in early 2020 and the significant impact it would have on fund performance. As a result, the Board reviewed performance data capturing more recent time periods, including performance data reflecting the first quarter of 2020 as well as performance data for various periods ended April 17, 2020 for its April Meeting and May 8, 2020 for its May Meeting.

The Board reviewed both absolute and relative fund performance during the annual review over the various time periods. With respect to the latter, the Board considered fund performance in comparison to the performance of peer funds (the “ Performance Peer Group ”) and recognized and/or customized benchmarks ( i.e., generally benchmarks derived from multiple recognized benchmarks). For funds that had changes in portfolio managers, the Board considered performance data of such funds before and after such changes. In considering performance data, the Board is aware of certain inherent limitations with such data, including that differences between the objective(s), strategies and other characteristics of the Nuveen funds compared to the respective Performance Peer Group and/or benchmark(s) (such as differences in the use of leverage) as well as differences in the composition of the Performance Peer Group over time will necessarily contribute to differences in performance results and limit the value of the comparative information. To assist the Board in its review of the comparability of the relative performance, the Adviser has ranked the relevancy of the peer group to the funds as low, medium or high.

As noted above, the Board reviewed fund performance over various periods ended December 31, 2019 as well as the first quarter of 2020 and various time periods ended April 17, 2020 and May 8, 2020. In light of the significant market decline in the early part of 2020, the Board noted that a shorter period of underperformance may significantly impact longer term performance. Further, the Board recognized that performance data may differ significantly depending on the ending date selected and accordingly, performance results for periods ended at the year-end of 2019 may vary significantly from performance results for periods ended in the first quarter of 2020, particularly given the extraordinary market conditions at that time as the impact of COVID-19 and other market developments unfolded. The Board considered a fund’s performance in light of the overall financial market conditions. In addition, the Board recognized that shareholders may evaluate performance based on their own holding periods which may differ from the periods reviewed by the Board and lead to differing results.

The secondary market trading of shares of the Nuveen closed-end funds continues to be a priority for the Board given its importance to shareholders, and therefore data reflecting the premiums and discounts at which the shares of the closed-end funds trade is reviewed by the Board during its annual review and by the Board and/or its Closed-end Fund committee during its respective quarterly meetings throughout the year.

In addition to the performance data prepared in connection with the annual review of the advisory agreements of the Nuveen funds, the Board reviewed fund performance throughout the year at its quarterly meetings representing differing time periods and took into account the discussions that occurred at these Board meetings in evaluating a fund’s overall performance. The Board also considered, among other things, the Adviser’s analysis of each Nuveen fund’s performance, with particular focus on funds that were considered performance outliers (both overperformance and underperformance), the factors contributing to the performance and any steps taken to address any performance concerns. Given the volatile market conditions of early 2020, the Board considered the Adviser’s analysis of the impact of such conditions on the Nuveen funds’ performance.

The Board evaluated performance in light of various factors, including general market conditions, issuer-specific information, asset class information, fund cash flows and other factors. Accordingly, depending on the facts and circumstances, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below its benchmark or peer group for certain periods. However, with respect to any Nuveen funds for which the Board had identified performance issues, the Board monitors such funds closely until performance improves, discusses with the Adviser the reasons for such results, considers whether any steps are necessary or appropriate to address such issues, and reviews the results of any efforts undertaken.

The Board’s determinations with respect to each Fund are summarized below.

For the AMT-Free Municipal Credit Income Fund, the Board noted that the Fund outperformed its blended benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund still outperformed its blended benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended March 31, 2020. In its review, the Board, however, noted that the Performance Peer Group was classified as low for relevancy. The Board was satisfied with the Fund’s overall performance.

For the Municipal Credit Income Fund, the Board noted that the Fund outperformed its blended benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, although the Fund’s performance was below the performance of its blended benchmark for the one-year period ended March 31, 2020, the Fund outperformed its blended benchmark for the three- and five-year periods ended March 31, 2020. Further, although the Fund ranked in the third quartile of its Performance Peer Group for the one-year period ended March 31, 2020, the Fund ranked in the first quartile for the three- and five-year periods ended March 31, 2020. In its review, the Board, however, noted that the Performance Peer Group was classified as low for relevancy. The Board was satisfied with the Fund’s overall performance.

For the Municipal High Income Opportunity Fund, the Board noted that the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, although the Fund’s performance was below the performance of its benchmark for the one- and five-year periods ended March 31, 2020, the Fund outperformed its benchmark for the three-year period ended March 31, 2020. Further, although the Fund ranked in the third quartile of its Performance Peer Group for the one-year period ended March 31, 2020, the Fund ranked in the first quartile for the three- and five-year periods ended March 31, 2020. The Board was satisfied with the Fund’s overall performance.

C. Fees, Expenses and Profitability

Fees and Expenses

As part of its annual review, the Board considered the contractual management fee and net management fee (the management fee after taking into consideration fee waivers and/or expense reimbursements, if any) paid by a Nuveen fund to the Adviser in light of the nature, extent and quality of the services provided. The Board also considered the total operating expense ratio of each Nuveen fund before and after any fee waivers and/or expense reimbursements. More specifically, the Independent Board Members reviewed, among other things, each fund’s gross and net management fee rates ( i.e., before and after expense reimbursements and/or fee waivers, if any) and net total expense ratio in relation to those of a comparable universe of funds (the “ Peer Universe ”) established by Broadridge. The Independent Board Members reviewed the methodology Broadridge employed to establish its Peer Universe and recognized that differences between the applicable fund and its respective Peer Universe as well as changes to the composition of the Peer Universe from year to year may limit some of the value of the comparative data. The Independent Board Members also considered a fund’s operating expense ratio as it more directly reflected the shareholder’s costs in investing in the respective fund.

215

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

In their review, the Independent Board Members considered, in particular, each Nuveen fund with a net expense ratio (excluding investment-related costs of leverage) of six basis points or higher compared to that of its peer average (each, an “ Expense Outlier Fund ”), including the Municipal Credit Income Fund, and an analysis as to the factors contributing to each such fund’s higher relative net expense ratio. In addition, although the Board reviewed a fund’s total net expenses both including and excluding investment-related expenses (i.e., leverage costs) and taxes for certain of the closed-end funds, the Board recognized that leverage expenses will vary across funds and in comparison to peers because of differences in the forms and terms of leverage employed by the respective fund. Accordingly, in reviewing the comparative data between a fund and its peers, the Board generally considered the fund’s net expense ratio and fees (excluding leverage costs and leveraged assets) to be higher if they were over 10 basis points higher, slightly higher if they were 6 to 10 basis points higher, in line if they were within approximately 5 basis points higher than the peer average and below if they were below the peer average of the Peer Universe. The Independent Board Members also considered, in relevant part, a fund’s net management fee and net total expense ratio in light of its performance history.

In their review of the fee arrangements for the Nuveen funds, the Independent Board Members considered the management fee schedules, including the complex-wide and fund-level breakpoint schedules. The Board noted that across the Nuveen fund complex, the complex-wide fee breakpoints reduced fees by $56.6 million and fund-level breakpoints reduced fees by $66.8 million in 2019.

With respect to the Sub-Adviser, the Board also considered the sub-advisory fee schedule paid to the Sub-Adviser in light of the sub-advisory services provided to the respective Fund, the breakpoint schedule and comparative data of the fees the Sub-Adviser charges to other clients, if any. In its review, the Board recognized that the compensation paid to the Sub-Adviser is the responsibility of the Adviser, not the Funds.

The Independent Board Members noted that (a) the AMT-Free Municipal Credit Income Fund had a net management fee that was higher than its peer average, but a net expense ratio that was in line with its peer average; (b) the Municipal High Income Opportunity Fund had a net management fee that was in line with its peer average and a net expense ratio that was below its peer average; and (c) the Municipal Credit Income Fund had a net management fee that was higher than its peer average and a net expense ratio that was slightly higher than its peer average. The Independent Board Members noted that the Municipal Credit Income Fund’s net expense ratio was slightly higher than its peer average due, in part, to such Fund’s larger allocation to non-investment grade securities compared to the peers.

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.

Comparisons with the Fees of Other Clients

In determining the appropriateness of fees, the Board also considered information regarding the fee rates the respective Fund Advisers charged to certain other types of clients and the type of services provided to these other clients. With respect to the Adviser and/or the Sub-Adviser, such other clients may include retail and institutional managed accounts, passively managed exchange-traded funds (“ETFs”) sub-advised by the Sub-Adviser but that are offered by another fund complex and municipal managed accounts offered by an unaffiliated adviser. With respect to the Sub-Adviser, the Board reviewed, among other things, the fee range and average fee of municipal retail wrap accounts and municipal institutional accounts.

In considering the fee data of other clients, the Board considered, among other things, the differences in the amount, type and level of services provided to the Nuveen funds relative to other clients as well as the differences in portfolio investment policies, investor profiles, account sizes and regulatory requirements, all of which contribute to the variations in the fee schedules. The Board recognized the complexity and myriad of services the Adviser had provided to the Nuveen funds compared to the other types of clients as the Adviser is principally responsible for all aspects of operating the funds, including complying with the increased regulatory requirements required when managing the funds as well as the increased entrepreneurial, legal and regu-

216

latory risks that the Adviser incurs in sponsoring and managing the funds. Further, with respect to ETFs, the Board considered that Nuveen ETFs are passively managed compared to the active management of the other Nuveen funds which contributed to the differences in fee levels between the Nuveen ETFs and other Nuveen funds. In general, higher fee levels reflect higher levels of service provided by the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that the Sub-Adviser’s fee is essentially for portfolio management services and therefore more comparable to the fees it receives for retail wrap accounts and other external sub-advisory mandates. The Board concluded the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.

Profitability of Fund Advisers

In their review, the Independent Board Members considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2019 and 2018. The Board reviewed, among other things, Nuveen’s net margins (pre-tax) (both including and excluding distribution expenses); gross and net revenue margins (pre- and post-tax); revenues, expenses, and net income (pre-tax and after-tax and before distribution) of Nuveen for fund advisory services; and comparative profitability data comparing the margins of Nuveen compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) for each of the last two calendar years. The Board also reviewed the revenues and expenses the Adviser derived from its ETF product line for the 2018 and 2019 calendar years.

In reviewing the profitability data, the Independent Board Members recognized the subjective nature of calculating profitability as the information is not audited and is dependent on cost allocation methodologies to allocate expenses of Nuveen and its affiliates between the fund and non-fund businesses. The expenses to be allocated include direct expenses in servicing the Nuveen funds as well as indirect and/or shared costs (such as overhead, legal and compliance) some of which are attributed to the Nuveen funds pursuant to the cost allocation methodologies. The Independent Board Members reviewed a description of the cost allocation methodologies employed to develop the financial information and a summary of the history of changes to the methodology over the eleven-year period from 2008 to 2019. The Board had also appointed three Independent Board Members, along with the assistance of independent counsel, to serve as the Board’s liaisons to review the development of the profitability data and any proposed changes to the cost allocation methodology prior to incorporating any such changes and to report to the full Board. The Board recognized that other reasonable and valid allocation methodologies could be employed and could lead to significantly different results. Based on the data, the Independent Board Members noted that Nuveen’s net margins were higher in 2019 than the previous year and considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between the years. The Board also noted the reinvestments of some of the profits into the business through, among other things, the investment of seed capital in certain funds and continued investments in enhancements to information technology, internal infrastructure and data management improvements and global investment and innovation projects.

As noted above, the Independent Board Members also considered Nuveen’s margins from its relationship to the Nuveen funds compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) to Nuveen for the calendar years 2019 and 2018. The Independent Board Members noted that Nuveen’s margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers. The Independent Board Members, however, recognized that it is difficult to make comparisons of profitability with other investment adviser peers given that comparative data is not generally public and the calculation of profitability is subjective and affected by numerous factors (such as types of funds a peer manages, its business mix, its cost of capital, the numerous assumptions underlying the methodology used to allocate expenses and other factors) which can have a significant impact on the results.

217

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

Aside from Nuveen’s profitability, the Board recognized that the Adviser is a subsidiary of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). As such, the Board also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2019 and 2018 calendar years to consider the financial strength of TIAA. The Board recognized the benefit of having an investment adviser and its parent with significant resources, particularly during periods of market stress.

In addition to Nuveen, the Independent Board Members also considered the profitability of the Sub-Adviser from its relationships with the Nuveen funds. In this regard, the Independent Board Members reviewed, among other things, the Sub-Adviser’s revenues, expenses and net revenue margins (pre- and post-tax) for its advisory activities for the calendar year ended December 31, 2019 as well as its pre-tax and after-tax net revenue margins for 2019 compared to such margins for 2018. The Independent Board Members also reviewed a profitability analysis reflecting the revenues, expenses and revenue margin (pre- and post-tax) by asset type for the Sub-Adviser for the calendar year ended December 31, 2019 and the pre- and post-tax revenue margins from 2019 and 2018.

In evaluating the reasonableness of the compensation, the Independent Board Members also considered any other ancillary benefits derived by the respective Fund Adviser from its relationship with the Nuveen funds as discussed in further detail below.

Based on a consideration of all the information provided, the Board noted that Nuveen’s and the Sub-Adviser’s level of profitability was acceptable and not unreasonable in light of the services provided.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

The Board considered whether there have been economies of scale with respect to the management of the Nuveen funds and whether these economies of scale have been appropriately shared with the funds. The Board recognized that although economies of scale are difficult to measure, there are several methods to help share the benefits of economies of scale, including breakpoints in the management fee schedule, fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in Nuveen’s business which can enhance the services provided to the funds for the fees paid. The Board noted that Nuveen generally has employed these various methods. In this regard, the Board noted that the management fee of the Adviser is generally comprised of a fund-level component and a complex-level component each with its own breakpoint schedule, subject to certain exceptions. The Board reviewed the fund-level and complex-level fee schedules. The Board considered that the fund-level breakpoint schedules are designed to share economies of scale with shareholders if the particular fund grows, and the complex-level breakpoint schedule is designed to deliver the benefits of economies of scale to shareholders when the eligible assets in the complex pass certain thresholds even if the assets of a particular fund are unchanged or have declined. With respect to the Nuveen closed-end funds, the Board noted that, although such funds may from time to time make additional share offerings, the growth of their assets would occur primarily through the appreciation of such funds’ investment portfolios. Further, in the calculation of the complex-level component, the Board noted that it had approved the acquisition of several Nuveen funds by similar TIAA-CREF funds in 2019. However, to mitigate the loss of the assets of these Nuveen funds deemed eligible to be included in the calculation of the complex-wide fee when these Nuveen funds left the complex upon acquisition, Nuveen agreed to credit approximately $460 million to assets under management to the Nuveen complex in calculating the complex-wide component.

The Independent Board Members also recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system and other systems and platforms that will, among other things, support growth, simplify and enhance information sharing, and enhance the investment process to the benefit of all of the Nuveen funds.

Based on its review, the Board concluded that the current fee arrangements together with the Adviser’s reinvestment in its business appropriately shared any economies of scale with shareholders.

218

E. Indirect Benefits

The Independent Board Members received and considered information regarding other benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the Nuveen funds. The Board considered the compensation that an affiliate of the Adviser received for serving as co-manager in the initial public offerings of new closed-end funds and for serving as an underwriter on shelf offerings of existing closed-end funds. In addition, the Independent Board Members also noted that various sub-advisers (including the Sub-Adviser) may engage in soft dollar transactions pursuant to which they may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds, although the Board recognized that certain sub-advisers may be phasing out the use of soft dollars over time.

The Board, however, noted that the benefits for the Sub-Adviser when transacting in fixed-income securities may be more limited as such securities generally trade on a principal basis and therefore do not generate brokerage commissions. Further, the Board considered that although the Sub-Adviser may benefit from the receipt of research and other services that it may otherwise have to pay for out of its own resources, the research may also benefit the Nuveen funds to the extent it enhances the ability of the Sub-Adviser to manage such funds or is acquired through the commissions paid on portfolio transactions of other clients.

Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable and within acceptable parameters.

F. Other Considerations

The Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including the Independent Board Members, concluded that the terms of each Advisory Agreement were fair and reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed.

PART II

Nuveen Dynamic Municipal Opportunities Fund

At a meeting held on January 23, 2020 (the “ Meeting ”), the Board Members, including the Independent Board Members, considered and approved the investment management agreement (for purposes of this Part II, the “Investment Management Agreement” ) pursuant to which Nuveen Fund Advisors, LLC (the “ Adviser ”) serves as investment adviser to Nuveen Dynamic Municipal Opportunities Fund (for purposes of this Part II, the “ Fund ”) and the investment sub-advisory agreement (for purposes of this Part II, the “ Sub-Advisory Agreement ”) pursuant to which Nuveen Asset Management, LLC (the “ Sub-Adviser ”) serves as investment sub-adviser to the Fund. For purposes of this Part II, the Adviser and the Sub-Adviser are each hereafter a “ Fund Adviser. ” In addition, for purposes of this Part II, the Investment Management Agreement and the Sub-Advisory Agreement are each hereafter an “ Advisory Agreement ” and collectively, the “ Advisory Agreements. ”

To assist the Board in its evaluation of an Advisory Agreement with a Fund Adviser at the Meeting, the Independent Board Members had received, in adequate time in advance of the Meeting or at prior meetings, materials which outlined, among other things:

• the nature, extent and quality of the services expected to be provided by the Fund Adviser;

• the organization of the Fund Adviser, including the responsibilities of various departments and key personnel;

• the expertise and background of the Fund Adviser with respect to the Fund’s investment strategy;

• certain performance-related information (as described below);

• the profitability of Nuveen and its affiliates for their advisory activities;

219

Table of Contents

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

• the proposed management fees of the Fund Adviser, including comparisons of such fees with the management fees of comparable funds;

• the expected expenses of the Fund, including comparisons of the Fund’s expected expense ratio with the expense ratios of comparable funds; and

• the soft dollar practices of the Fund Adviser, if any.

At the Meeting and/or prior meetings, the Adviser made presentations to and responded to questions from the Board. During the Meeting and/or prior meetings, the Independent Board Members also met privately with their legal counsel to, among other things, review the Board’s duties under the 1940 Act, the general principles of state law in reviewing and approving advisory contracts, the standards used by courts in determining whether investment company boards of directors have fulfilled their duties, factors to be considered in voting on advisory contracts and an adviser’s fiduciary duty with respect to advisory agreements and compensation. It is with this background that the Independent Board Members considered the Advisory Agreements. As outlined in more detail below, the Independent Board Members considered various factors they believed relevant with respect to the Fund, including, among other things: (a) the nature, extent and quality of the services expected to be provided by the Fund Advisers; (b) investment performance, as described below; (c) the advisory fees and costs of the services expected to be provided to the Fund and the profitability of the Fund Advisers; (d) the extent of any anticipated economies of scale; (e) any benefits expected to be derived by the Fund Advisers from their relationships with the Fund; and (f) other factors. Each Board Member may have accorded different weight to the various factors in reaching his or her conclusions with respect to the Fund’s Advisory Agreements.

A. Nature, Extent and Quality of Services

The Independent Board Members considered the nature, extent and quality of the respective Fund Adviser’s services, including portfolio management services and administrative services. Given that the Adviser and the Sub-Adviser already serve as adviser and sub-adviser, respectively, to other Nuveen funds overseen by the Board Members, the Board has a good understanding of each such Fund Adviser’s organization, operations, personnel and services. As the Independent Board Members meet regularly throughout the year to oversee the Nuveen funds, including funds currently advised by the Fund Advisers, the Independent Board Members have relied upon their knowledge from their meetings and any other interactions throughout the year with the respective Fund Adviser in evaluating the Advisory Agreements.

At the Meeting and/or at prior meetings, the Independent Board Members reviewed materials outlining, among other things, the respective Fund Adviser’s organization and business; the types of services that such Fund Adviser or its affiliates provide to the Nuveen funds (as applicable) and are expected to provide to the Fund; and the experience of the respective Fund Adviser with applicable investment strategies. Further, at the Meeting and/or at prior meetings, the Independent Board Members have evaluated the background and experience of the relevant investment personnel.

With respect to services, the Board noted that the Fund would be a registered investment company that would operate in a regulated industry. In considering the services that were expected to be provided by the Fund Advisers, at the Meeting and/or at prior meetings, the Board has recognized the comprehensive set of services the Adviser provides to operate the Nuveen funds in a highly regulated industry. Some of the functions for which the Adviser is responsible include, but are not limited to: product management; investment oversight; securities valuation services; risk management; fund administration; oversight of shareholder services and transfer agency functions; board relations services; compliance and regulatory oversight services; legal support and oversight of outside law firms; and leverage, capital and distribution management services. In addition to the services provided by the Adviser, the Board has also considered the risks borne by the Adviser and its affiliates in managing the Nuveen funds, including entrepreneurial, operational, reputational, regulatory and litigation risks.

220

Table of Contents

The Independent Board Members noted that the Adviser would oversee the Sub-Adviser and recognized that the Sub-Adviser and its investment personnel generally would be responsible for the management of the Fund’s portfolio. In this regard, the Board Members recognized the Sub-Adviser’s relevant experience and expertise.

Based on their review, the Independent Board Members found that, overall, the nature, extent and quality of services expected to be provided to the Fund under each Advisory Agreement were satisfactory.

B. Investment Performance

The Fund was new and, therefore, did not have its own performance history. The Independent Board Members noted, however, that the Fund’s investment strategy was expected to be substantially similar to that of the Nuveen Strategic Municipal Opportunities Fund (the “ Strategic Fund ”), a Nuveen open-end fund which had an inception date of December 16, 2014. In this regard, the Independent Board Members reviewed certain performance information relating to the Strategic Fund, including performance history information for the one-year, three-year and five-year periods as of December 31, 2019.

C. Fees, Expenses and Profitability 1. Fees and Expenses

In evaluating the management fees and expenses that the Fund was expected to bear, the Independent Board Members considered, among other things, the Fund’s proposed management fee structure and its expected expense ratio in absolute terms as well as compared with the fees and expense ratios of comparable funds. Accordingly, the Independent Board Members reviewed, among other things, the proposed advisory fee and estimated net total expense ratio for the Fund (based on both common assets and total managed assets), as well as comparative fee and expense data pertaining to the Fund’s peers in the Lipper category in which the Fund is expected to be classified. In considering the Fund’s advisory fees, the Board also considered the differences between the investment strategy of the Fund and the investment strategies of the Strategic Fund, certain other Nuveen municipal closed-end funds and certain funds in the Fund’s expected Lipper category. Further, the Independent Board Members took into account the proposed sub-advisory fee for the Fund.

The Independent Board Members recognized that assets attributable to the Fund’s use of leverage would be included in the amount of assets upon which the advisory fee is calculated. In this regard, the Independent Board Members noted that the advisory fee is based on a percentage of average daily “Managed Assets.” “Managed Assets” generally 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 includes 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. The Independent Board Members recognized that the fact that a decision to employ or increase the Fund’s leverage will have the effect, all other things being equal, of increasing Managed Assets (and, in turn, increasing the Adviser’s and the Sub-Adviser’s management fees), means that the Adviser and the Sub-Adviser may have a conflict of interest in determining whether to use or increase leverage. The Independent Board Members noted, however, that the Adviser and the Sub-Adviser would seek to manage that potential conflict by recommending to the Board to leverage the Fund (or increase such leverage) when they determine that such action would be in the best interests of the 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.

The Independent Board Members considered the proposed management fee rate as a percentage of Managed Assets before any fund-level and complex-wide breakpoints. Based on their review of the fee and expense information provided, the Independent Board Members determined that the Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services to be provided to the Fund.

Comparisons with the Fees of Other Clients

At the Meeting and/or at prior meetings, the Board has reviewed information regarding the fee rates that the Fund Advisers charge for certain other types of clients and the type of services provided to these other clients. In conjunction with municipal funds, with respect to the Adviser and/or the Sub-Adviser, such other clients may include retail and institutional managed accounts, passively managed exchange-traded funds sub-advised by the Sub-Adviser but that are offered by another fund complex and municipal managed accounts offered by an unaffiliated adviser. With respect to the Sub-Adviser, the Board has previously reviewed, among other things, the fee range and average fee of municipal retail wrap accounts and municipal institutional accounts.

In addition to the comparative fee data, the Board has also reviewed, among other things, a description of the different levels of services provided to certain other clients compared to the services provided to the Nuveen funds as well as the differences in portfolio investment policies, investor profiles, account sizes and regulatory requirements, all of which contribute to the variations in the fee schedules. The Board has previously noted, among other things, the wide range of services in addition to investment management services provided to the Nuveen funds when the Adviser is principally responsible for all aspects of operating the funds, including the increased regulatory requirements that must be met in managing the funds, the larger account sizes of managed accounts and 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. Further, the Board has 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 has previously concluded that the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.

Profitability of Fund Advisers

In conjunction with their review of fees, at the Meeting and/or at prior meetings, the Independent Board Members have considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2018 and 2017. The Board has previously reviewed, among other things, Nuveen’s net margins (pre-tax) (both including and excluding distribution expenses); gross and net revenue margins (pre- and post-tax); revenues, expenses, and net income (pre-tax and after-tax and before distribution) of Nuveen for fund advisory services; and comparative profitability data comparing the margins of Nuveen compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) for the 2018 and 2017 calendar years. The Board has also reviewed the revenues and expenses the Adviser derived from its exchange-traded fund product line that was launched in 2016. The Independent Board Members have noted that Nuveen’s net margins were higher in 2018 than the previous year and considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between the years. The Board has considered the costs of investments in the Nuveen business, including the investment of seed capital in certain Nuveen funds and additional investments in infrastructure and technology. The Independent Board Members have also noted that Nuveen’s margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers; however, the Independent Board Members have recognized the inherent limitations of the comparative data of other publicly traded peers given that the calculation of profitability is rather subjective and numerous factors (such as types of funds, business mix, cost of capital, methodology to allocate expenses and other factors) can have a significant impact on the results.

Aside from Nuveen’s profitability, the Board has recognized that the Adviser is a subsidiary of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“ TIAA ”). As such, the Board has also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2018 and 2017 calendar years to consider the financial strength of TIAA having recognized the importance of having an adviser with significant resources.

222

Table of Contents

In addition, the Independent Board Members have reviewed the Sub-Adviser’s revenues, expenses and revenue margins (pre-and post-tax) for its advisory activities for the calendar year ended December 31, 2018. The Independent Board Members have also reviewed a profitability analysis reflecting the revenues, expenses and revenue margin (pre- and post-tax) by asset type for the Sub-Adviser for the calendar year ending December 31, 2018 and the pre- and post-tax revenue margin from 2018 and 2017.

In evaluating the reasonableness of the compensation, the Independent Board Members have also considered any other ancillary benefits derived by the respective Fund Adviser from its relationship with the Nuveen funds as discussed in further detail below.

Based on a consideration of all the information provided, the Board has noted that Nuveen’s and the Sub-Adviser’s level of profitability was acceptable and not unreasonable in light of the services provided.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

The Independent Board Members considered whether the Fund could be expected to benefit from any economies of scale. Although the Board has recognized that economies of scale are difficult to measure, the Independent Board Members have noted that economies of scale may be shared in various ways, including through breakpoints in the management fee schedule and through the Adviser’s investment in its business, which can enhance the services provided to the Nuveen funds. With respect to breakpoint schedules, because the Board has previously recognized that economies of scale may occur not only when the assets of a particular Nuveen fund grow, but also when the assets in the complex grow, the Nuveen funds generally pay the Adviser a management fee comprised of a fund-level component and a complex-level component, each with its own breakpoint schedule, subject to certain exceptions. In general terms, the breakpoint schedule at the fund level reduces fees as assets in the particular fund pass certain thresholds and the breakpoint schedule at the complex level reduces fees on the Nuveen funds as the eligible assets in the complex pass certain thresholds. Accordingly, the Independent Board Members reviewed and considered the proposed management fees for the Fund, taking into account the fund-level and complex-level breakpoint schedules. In this regard, however, the Fund is a closed-end fund and the Independent Board Members have recognized that although closed-end funds may from time to time make additional share offerings, the growth of their assets would occur primarily through the appreciation of such funds’ investment portfolios. In addition, the Independent Board Members have recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system as well as other systems and platforms that will, among other things, support growth, simplify and enhance information sharing, and enhance the investment process to the benefit of all of the Nuveen funds.

Based on their review, the Independent Board Members concluded that the proposed fee structure was acceptable and reflected economies of scale to be shared with the Fund’s shareholders when assets under management increase.

E. Indirect Benefits

The Independent Board Members received and considered information at the Meeting and/or at prior meetings regarding other benefits that a Fund Adviser or its affiliates may receive as a result of their relationship with the Nuveen funds. With respect to closed-end funds, the Independent Board Members have considered that an affiliate of the Adviser serves as co-manager in the initial public offerings of new closed-end funds for which it may receive revenue and serves as an underwriter on shelf offerings of existing closed-end funds for which it receives compensation.

In addition to the above, at the Meeting and/or at prior meetings, the Independent Board Members have noted that the Sub-Adviser engages in soft dollar transactions pursuant to which it may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds. The Board, however, has noted that the benefits for sub-advisers transacting in fixed-income securities may be more limited as such securities generally trade on a principal basis and therefore do not generate brokerage commissions. Further, the Board has noted that although the Sub-Adviser may benefit from the receipt of research and other services that it may otherwise have to pay for out of its own

223

resources, the research may also benefit a Nuveen fund to the extent it enhances the ability of the Sub-Adviser to manage such fund or is acquired through the commissions paid on portfolio transactions of other clients.

Based on their review, the Independent Board Members concluded that any indirect benefits expected to be received by a Fund Adviser as a result of its relationship with the Fund were reasonable and within acceptable parameters.

F. Approval

The Independent Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including a majority of the Independent Board Members, concluded that the terms of the Investment Management Agreement and the Sub-Advisory Agreement were fair and reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services to be provided to the Fund and that the Investment Management Agreement and Sub-Advisory Agreement should be and were approved on behalf of the Fund.

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 her absence, any other member of the Audit Committee).

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.

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.

“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.

Audit Committee Pre-Approval Policies and Procedures. Generally, the Audit Committee must approve (i) all non-audit services to be performed for the Fund by the Fund’s independent accountants and (ii) all audit and non-audit services to be performed by the Fund’s independent accountants for the Affiliated Fund Service Providers with respect to operations and financial reporting of the Fund. Regarding tax and research projects conducted by the independent accountants for the Fund and Affiliated Fund Service Providers (with respect to operations and financial reports of the Fund) such engagements will be (i) pre-approved by the Audit Committee if they are expected to be for amounts greater than $10,000; (ii) reported to the Audit Committee chair for her verbal approval prior to engagement if they are expected to be for amounts under $10,000 but greater than $5,000; and (iii) reported to the Audit Committee at the next Audit Committee meeting if they are expected to be for an amount under $5,000.

Nuveen Fund Advisors, LLC is the registrant’s investment adviser (also referred to as the “Adviser”). The Adviser is responsible for the selection and on-going monitoring of the Fund’s investment portfolio, managing the Fund’s business affairs and providing certain clerical, bookkeeping and administrative services. The Adviser has engaged Nuveen Asset Management, LLC (“Nuveen Asset Management” or “Sub-Adviser”) as Sub-Adviser to provide discretionary investment advisory services. The following section provides information on the portfolio manager at the Sub-Adviser: Item 8(a)(1). PORTFOLIO MANAGER BIOGRAPHIES

As of the date of filing this report, the following individual at the Sub-Adviser has primary responsibility for the day-to-day implementation of the Fund’s investment strategy:

Paul Brennan, CFA, CPA, manages several Nuveen municipal national and state mutual funds and closed-end bond funds. He has been portfolio manager of the Fund since 2006. Paul began his career in the investment business 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. He earned his B.S. in Accountancy and Finance from Wright State University. He is a CPA, has earned the Chartered Financial Analyst (CFA) designation, and currently sits on the Nuveen Asset Management Investment Management Committee.

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

In addition to the Fund, as of October 31, 2020, the portfolio manager is 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	10	$20.05 billion
	Other Pooled Investment Vehicles	1	$39.07 million
	Other Accounts	2	$53.27 million

Assets are as of October 31, 2020. 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 the portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

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

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

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

As of the most recently completed fiscal year end, the primary portfolio manager’s compensation is as follows:

Portfolio managers are compensated through a combination of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.

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

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

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

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

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