Chair’s Letter
to Shareholders
Dear Shareholders,
Financial markets have been receiving mixed messages over the past year. The global economy has bifurcated, split between a slumping manufacturing sector and a resilient consumer. Confidence has been weakened among corporate managements, who are wary of trade frictions and moderating global growth, but has remained elevated among consumers, who have benefited from tight labor markets and growing wages. As the economic cycle advances toward its later stage, corporate profits are shrinking and earnings forecasts are being downgraded. A waning growth outlook has held interest rates near historically low levels, while stock market indexes have overcome periodic volatility to touch historical highs.
While we continue to anticipate slower economic growth and increased market volatility, we note that recession fears have receded from earlier in the year. The U.S. economy held steady in the third quarter, and nearer-term economic indicators have provided upside surprises. Consumer confidence remains underpinned by low unemployment and modest wage growth. Looser financial conditions, in part driven by the Federal Reserve’s three interest rate cuts in 2019, have revived momentum in the housing market and should continue to encourage borrowing by consumers and businesses. Outside the U.S., Germany avoided a recession in the second half of 2019 and other eurozone economic indicators are pointing to stabilization and improving sentiment. Consumers in Europe and Japan, like those in the U.S., have remained supported by jobs growth and rising wages. Although the outcomes of trade, Brexit and other geopolitical concerns continue to be uncertain, some clarity on these issues could be a potential source of upside.
At Nuveen, we still see investment opportunities in the maturing economic environment, but we are taking a selective approach. If you’re concerned about where the markets are headed from here, we encourage you to work with your financial advisor to review your time horizon, risk tolerance and investment goals. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.
Sincerely,
Terence J. Toth
Chair of the Board
December 23, 2019

These Funds feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen, LLC. Portfolio managers John V. Miller, CFA, Steve M. Hlavin, Paul L. Brennan, CFA, Scott R. Romans, PhD and discuss U.S. economic and municipal market conditions, key investment strategies and the twelve-month performance of NVG, NZF and NMZ and the performance of NMCO in the abbreviated reporting period since its inception on September 16, 2019. Paul has managed NVG since 2006, Scott assumed portfolio management responsibility for NZF in 2016, John has managed NMZ since its inception in 2003 and John and Steve have managed NMCO since its inception.
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 (subsequent to the close of this reporting period).
What factors affected the U.S. economy and the national municipal market during the twelve-month reporting period ended October 31, 2019?
The U.S. economy reached the tenth year of expansion since the previous recession ended in June 2009, marking the longest expansion in U.S. history. In the third quarter of 2019, gross domestic product (GDP) grew at an annualized rate of 2.1%, according to the “second” estimate by the Bureau of Economic Analysis. 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. Growth in consumer spending and the housing sector helped offset a decline in business investment during the July to September 2019 period. By comparison, annualized GDP growth was 2.0% in the second quarter and 3.1% in the first quarter.
Consumer spending, the largest driver of the economy, remained well supported by low unemployment, wage gains and tax cuts. As reported by the Bureau of Labor Statistics, the unemployment rate fell to 3.6% in October 2019 from 3.8% in October 2018 and job gains averaged around 174,000 per month for the past twelve months. As the jobs market has tightened, average hourly earnings grew at an annualized rate of 3.0% in October 2019. However, falling energy prices dampened inflation over the past twelve months. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 1.8% over the twelve-month reporting period ended October 31, 2019 before seasonal adjustment.

Portfolio Managers’ Comments (continued)
Low mortgage rates and low inventory drove home prices moderately higher in this reporting period, despite declining new home sales and housing starts. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, was up 3.2% year-over-year in September 2019 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 1.5% and 2.1%, respectively.
As data pointed to slower momentum in the overall economy, the Federal Reserve (Fed) notably shifted its stance. Although the Fed had indicated in December 2018 that there could be two more rate hikes in 2019, global growth concerns kept the central bank on the sidelines. As expected by the markets, the Fed left rates unchanged throughout the first half of 2019 while speculation increased that the Fed’s next move would be a rate cut. At the July 2019, September 2019 and October 2019 policy committee meetings, the Fed announced a 0.25% cut to its main policy rate. Markets registered disappointment with the Fed’s explanation that the rate cuts were a “mid-cycle adjustment,” rather than a prolonged easing period, and its signal that there would be no additional rate cuts in 2019. Also in the latter half of 2019, the Fed announced it would stop shrinking its bond portfolio sooner than scheduled, as well as began buying short-term Treasury bills to help money markets operate smoothly and maintain short-term borrowing rates at low levels. Fed Chairman Powell emphasized that the Treasury bill purchases were not a form of quantitative easing.
During the twelve-month reporting period, geopolitical news remained a prominent market driver. Tariff and trade policy topped the list of concerns, most prominently the U.S.-China relations. After several rounds of talks and a series of tariff increases, President Trump and President Xi agreed to another temporary trade truce in late June 2019 that halted additional tariff increases. Tensions increased markedly after the July 2019 negotiations ended without an agreement, with both China and the U.S. increasing import duties. After setting new trade meetings in September and October 2019, tariff waivers were announced on a selected group of U.S. and Chinese goods and the two sides signaled progress toward a partial trade deal. The U.S., Mexico and Canada Agreement (USMCA) trade deal replacing the North American Free Trade Agreement had yet to be ratified by the national congresses (subsequent to the close of the reporting period, the trade deal was passed by the House of Representatives), while President Trump rescinded the threat to impose tariffs on Mexico if the country didn’t take more action to curb illegal immigration. With the U.S. House of Representatives opening an impeachment inquiry into President Trump, ratification of the USMCA deal was expected to be delayed. The Trump administration delayed imposing auto tariffs on the European Union (EU), as it continued to focus more on the China trade negotiations, but duties on $7.5 billion worth of EU goods including wine and cheese went into effect in October 2019 in retaliation for a dispute over aircraft subsidies. Global manufacturing and export data continued to show evidence of trade-related slumps, which increased worries that the slowdown would spread into other segments of the global economy.
In the U.K., Prime Minister Theresa May was unable to secure a Brexit deal before the original March 29, 2019 deadline and resigned as of June 7, 2019. The EU extended the deadline to October 31, 2019, which Prime Minister May’s successor, Boris Johnson, was unable to meet after a series of political maneuvers failed to secure an approval for his exit plan. In October 2019, the EU approved a “flextension” to January 31, 2020 and a U.K. general election was scheduled for December (subsequent to the close of the reporting period, on December 19, 2019, the British Parliament passed the Brexit Bill). In Italy, investors worried about another potential budget clash between the eurosceptic coalition government and the EU. However, following the unexpected resignation of the prime minister in August 2019, the newly formed coalition government appeared to take a less antagonistic stance. Europe also contended with the “yellow vest” protests in France, immigration policy concerns, Russian sanctions and political risk in Turkey.
Elections around the world also remained a source of uncertainty. Markets continued to closely monitor the new administrations in Brazil and Mexico, as well as Argentina’s presidential election. Incumbent candidate President Macri, seen as market-friendly, suffered a surprising defeat in the August 2019 primary, and the Peronist ticket of Alberto Fernandez/Cristina Fernandez de Kirchner won as expected in the October 2019 election. Europe’s traditional centrist parties lost seats in the Parliamentary elections and populist parties saw marginal gains. The ruling parties in India and South Africa maintained their majorities, where slower economic growth could complicate their respective reform mandates.
Municipal bonds delivered strong performance over the twelve-month reporting period. The significant decline in interest rates was the main driver of higher municipal bond prices, with positive technical and fundamental conditions also supporting credit spread tightening. At the start of the reporting period, the prevailing economic outlook was generally positive and the Fed had been increasing its main policy interest rate, driving the 10-year U.S. Treasury yield to a high of 3.24% in November 2018. However, sentiment shifted sharply at the end of 2018, causing a reversal in market conditions. Interest rates declined significantly over the remainder of the reporting period on signs of a weaker macroeconomic environment, more dovish central bank policy, geopolitical tensions (especially regarding trade) and bouts of equity market volatility. The U.S. Treasury yield curve flattened overall, with a
6

portion of the curve temporarily inverting from late August 2019 to late September 2019. The municipal yield curve also flattened overall, particularly from the 2-year to 20-year segment. Despite concerns about the broader economic outlook, credit conditions remained favorable for municipal credits. State tax revenues have increased across the 50 states and a healthy housing market added to local government tax revenues. Defaults in 2019 so far have been mainly confined to idiosyncratic situations.
Municipal bond gross issuance nationwide totaled $378.2 billion in this reporting period, a 6.9% decrease from the issuance for the twelve-month reporting period ended October 31, 2018. Nevertheless, 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. Although the pace of refundings is slowing, net negative issuance is expected to continue. Notably, taxable municipal bond issuance has increased meaningfully in 2019. The Tax Cut and Jobs Act of 2017 prohibits municipal issuers from issuing new tax-exempt bonds to pre-refund existing tax-exempt bonds. However, municipalities have taken advantage of the low interest rate environment and the strong demand for yield to issue taxable municipal debt, enabling them to save on net interest costs.
Demand for municipal bonds has been robust. Cash flows into municipal bond funds have been consistently positive year-to-date in 2019. Low interest rates in the U.S. and globally have continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have begun to assess the impact of the 2017 tax law, which caps the state and local tax (SALT) deduction for individuals, there has been increased demand for tax-exempt municipal bonds in 2019 to date, especially in states with high income and/or property taxes.
What key strategies were used to manage NVG, NZF and NMZ during the twelve-month reporting period and NMCO during the abbreviated reporting period ended October 31, 2019?
Each Fund’s primary investment objective is to provide current income exempt from regular federal income tax by investing primarily in a portfolio of municipal obligations issued by state and local government authorities or certain U.S. territories.
Municipal bond performance was strongly positive in the reporting period. Municipal yields fell across all maturities and the yield curve flattened, which resulted in the outperformance of longer maturity bonds over shorter maturity bonds. Positive credit conditions and strong demand for higher yielding assets and tax-exempt income helped credit spreads remain stable to improving.
During this time, 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. Generally speaking, throughout this reporting period, the Funds maintained their overall positioning strategies in terms of duration and yield curve positioning, credit quality exposures and sector allocations.
In NVG, trading activity was relatively muted compared to historical norms. We considered the portfolio to be well positioned for the market conditions and, given the low interest rate environment, the opportunity set was generally less appealing. Additionally, call activity has lessened, reducing the need to reinvest cash into new names. As a result of a lower portfolio turnover in this reporting period, the duration of the underlying portfolio drifted lower (which was beneficial when interest rates rose slightly at the end of the period) and the effective leverage ratio declined. Nevertheless, we continued to trade opportunistically when attractive deals were available. Our purchases skewed slightly toward higher quality bonds as relative value opportunities were fewer among lower rated and longer duration bonds. We bought several hospital bonds (Indiana University, University of Alabama, Mosaic Health System, Essentia and Trinity), higher education (Stanford University), Puerto Rico sales tax bonds (known as COFINAs), Puerto Rico Aqueduct and Sewer Authority (PRASA) and Chicago Board of Education.
NZF added lower rated (mainly single A, BBB and BB) credits in the fourth quarter of 2018 when interest rates were higher and credit spreads were wider relative to the rest of the reporting period. Most of these additions were in hospital and health care bonds. As interest rates declined and credit spreads contracted toward the end of 2018 and throughout 2019, those opportunities dissipated. In February-March 2019, we began to rotate NZF out of tobacco settlement bonds and into Puerto Rico bonds. While the Fund’s tobacco holdings performed well in the past, we believe the credit outlook has become less favorable amid declining consumption trends and disruptive new technologies (vaping/e-cigarettes). The prospects for certain Puerto Rico credits, however, appeared more
7

attractive. PRASA has maintained sufficiently strong operations to avoid default and is expected to receive federal infrastructure funding in the coming years. COFINAs were the first major credit to exit the bankruptcy-like restructuring process and were restructured with improved security features. We purchased both PRASA and COFINA bonds during this reporting period, using the proceeds from trimming the tobacco exposure. Outside of the tobacco-Puerto Rico repositioning, the proceeds of called and maturing bonds funded most of NZF’s buying activity. We also sold some high grade “placeholder” bonds that were bought when interest rates were low and some short dated bonds that were near to rolling out of the portfolio to fund buying in new opportunities.
For NMZ, we continued to emphasize longer duration securities and maintaining the portfolio’s overall duration near its benchmark target, while seeking to add value through individual credit selection and earning high income from high yield bonds. NMZ continued to invest along its longstanding themes of project finance and improving credit stories when spreads were attractive to do so, while supporting the Fund’s income earnings. This resulted in relatively higher exposure to sectors such as hospitals, real estate-backed, charter schools and Illinois-related, and lower exposure to sectors such as tobacco securitization, Puerto Rico and senior living facilities/continuing care retirement communities. During this reporting period, we had a significant opportunity to put cash to work from the proceeds of called and maturing bonds. We bought Virgin Trains USA (formerly known as Brightline), a high-speed passenger rail system in southeastern Florida. In early 2019, Virgin Trains USA issued a large bond offering to finance the train line’s extension to Orlando, and the bond was available at attractive credit spread levels. The industrial development (IDR) revenue sector was another source of opportunity for NMZ, as attention to environmental impact has garnered more investment interest. We added a project finance bond offering an attractive tax exempt yield for Fulcrum Sierra Biofuels, a project that converts municipal solid waste into transportation fuels.
As of October 31, 2019, 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. As part of our duration management strategies, NVG entered into interest rate swap agreements to help reduce price volatility risk due to movements in U.S. interest rates relative to the Fund’s benchmark. While the interest rate swaps detracted modestly from performance due to falling interest rates during this reporting period, they enabled the Fund to invest in longer duration bonds that were key contributors to performance and that helped support the Fund’s dividend. The swap position was eliminated from NVG prior to the end of the reporting period.
NMCO began operations in mid-September 2019, and since then we have worked to fully invest the Fund’s portfolio in high yielding, low- to medium-quality municipal securities (rated Baa/BBB or lower or comparable quality) that support high income earnings and offer total return potential. Consistent with the Fund’s 12-year term (terminating in 2031), NMCO sought to invest in newly and recently issued project finance revenue bonds across a range of sectors. By the end of the reporting period, NMCO held more than 75% of the portfolio in high yield bonds rated BBB and below.
How did NVG, NZF and NMZ perform during the twelve-month reporting period and NMCO perform in the abbreviated reporting period ended October 31, 2019?
The tables in each Fund’s Performance Overview and Holding Summaries section of this report provide the Funds’ total returns for the one-year, five-year, ten-year and since inception periods ended October 31, 2019. Each Fund’s total returns at net asset value (NAV) are compared with the performance of a corresponding market index.
For the twelve months ended October 31, 2019, the total returns at NAV for NVG, NZF and NMZ outperformed the return for the national S&P Municipal Bond Index. NVG and NZF outperformed 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 outperformed the return on the S&P Municipal Yield Index. For the abbreviated reporting period, the total returns at NAV for NMCO underperformed the return of the S&P Municipal Yield Index.
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 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 outperformed.
Credit ratings allocations were positive contributors to NVG and NZF’s performance but the contribution was smaller than that of duration and yield curve positioning. Both Funds emphasized medium and lower grade credit qualities over high quality bonds, which was
8

advantageous as lower rated bonds outperformed the highest grade (AAA and AA rated) paper. As interest rates fell during the reporting period, investors sought higher yields among lower rated credits, which contributed to spread tightening in the lower rated segments. NZF’s exposure to non-rated bonds was a mild detractor from performance, but the favorable positioning across the rest of the credit spectrum more than offset the small negative impact.
Sector positioning also added modestly to performance for NVG and NZF. NVG’s overweight allocations to the health care, tobacco settlement and higher education sectors were the most favorable to performance, with security selection also beneficial in each of these sectors. An underweight to the slightly outperforming aggregate tax supported sectors wasn’t noteworthy in terms of performance impact, but our security selection was strong, led by positions in Illinois and Chicago debt, New Jersey debt and American Dream Meadowlands, a retail and entertainment mega complex in New Jersey. NVG also benefited from its security selection in public power credits including Santee Cooper Electric and Oglethorpe Power. However, an overweight to the pre-refunded sector detracted as these bonds lagged due to their short duration and high credit quality. In NZF, overweight allocations to the dedicated tax sector, which includes COFINAs, and the health care sectors were advantageous as both sectors performed well. However, NZF’s underweight to the “other transportation” sector slightly detracted as the sector outperformed.
NMZ’s performance, which is primarily compared to the S&P Municipal Yield Index, continued to be driven by our bottom-up credit selection. Price appreciation, stable credit spreads and the enhanced income from NMZ’s holdings contributed to the Fund’s relative outperformance over the benchmark in this reporting period. Among NMZ’s top contributors to performance were Illinois and Chicago credits. A change in the political and governmental environments at both the state of Illinois and the city of Chicago boosted investor confidence in the state’s financial health, the funding of the Chicago Public Schools system and the overall cooperation between the city and the state. NMZ’s holdings in Chicago O’Hare airport, Chicago Board of Education and Illinois Financing Authority for Presence Health Network were beneficiaries of the improved outlook and were also among the largest positions in the Fund. Real estate development bonds were another source of outperformance. New York Liberty 3 World Trade Center bonds, financing an 85-story office tower in Manhattan, benefited from narrowing credit spreads as the project nears completion and occupancy rates reached a critical level that should enable the project to meet its debt obligation. The American Dream Meadowlands mega-mall and entertainment complex is another real estate development project that recently opened its first phase, which has supported positive investor sentiment. The health care sector also delivered strong results, as we avoided the troubled senior living facilities segment and instead owned strong performing hospitals such as the aforementioned Presence Health in Chicago, Northwestern Memorial Health (also in Chicago) and Loma Linda University Medical Center in California. Loma Linda has incurred significant debt with the multi-billion dollar reconstruction of its flagship facility, but the strength of the hospital’s reputation has underpinned the bond’s strong performance. In addition, the Loma Linda credits benefited from a generally positive outlook for the state of California and the increased scarcity value of tax exempt California debt amid the tax law changes. One of NMZ’s special situation/turnaround bonds was also a notable contributor. FirstEnergySolutions, which has been undergoing a bankruptcy reorganization, appreciated on continued progress in its debt restructuring and a favorable regulatory ruling in the state of Ohio.
There were few material detractors among NMZ’s holdings in this reporting period. Tri-Valley Learning Corp., a California charter school, had a modest negative impact as the school filed for bankruptcy and has been liquidating its assets. We consider the situation to be highly idiosyncratic and it does not alter our fundamental view of the charter school sector as a longstanding source of attractive opportunities.
During the abbreviated reporting period for NMCO, interest rates began to trend higher. Yields on high grade municipal bonds rose while yields on high yield municipal bonds were unchanged, causing credit spreads to contract on average. Although NMCO remained in the invest-up period during this time, the Fund benefited from strong results in the tobacco securitization and IDR sectors, as well as positions in FirstEnergy Solutions and U.S. Steel. Conversely, Puerto Rico Electric Power Authority (PREPA) bond prices fell due to negative headlines about the debt restructuring agreement, detracting from NMCO’s performance in the abbreviated reporting period. However, the outperformance of the aforementioned holdings more than offset the negative impact from PREPA.
In addition, the use of regulatory leverage was an important factor affecting performance of NVG, NZF and NMZ. Leverage is discussed in more detail later in the Fund Leverage section of this report.

Fund Leverage
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 the Fund pays on its leveraging instruments are lower than the interest the Fund earns on its portfolio of long-term bonds that it has bought with the proceeds of that leverage. 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, which will make the shares’ net asset value more volatile, and 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 all-time lows after the 2007-2009 financial crisis, which has contributed to a reduction in common share net income and long-term total return potential, leverage nevertheless continues to provide the opportunity for incremental common share income. Management believes that the potential benefits from leverage continue to outweigh the associated increase in risk and volatility previously described.
Leverage had a positive impact on the total return performance of NVG, NZF and NMZ over the reporting period. Leverage from inverse floating rate securities had a negligible impact on the total return performance of NMCO over the reporting period.
As of October 31, 2019, the Funds’ percentages of leverage are as shown in the accompanying table.

| NVG | NZF | NMZ | NMCO
Effective Leverage* | 37.42% | 37.24% | 37.34% | 3.43%
Regulatory Leverage* | 34.32% | 36.66% | 8.24% | 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.

Taxable-Equivalent Yield** |  |  | 8.03 | % |  |  | 8.31 | % |  |  | 8.38 | %

* | Distribution paid in December 2018.
** | 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%. 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.

On October 29, 2019, NMCO declared its initial distribution of $0.0640 per share to shareholders of record on November 15, 2019 (subsequent to the close of this reporting period), which was paid on December 2, 2019.
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.

Risk Considerations
Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation.
Nuveen AMT-Free Municipal Credit Income Fund (NVG)
Investing in closed-end funds involves risk; principal loss is possible. There is no guarantee the Fund’s investment objectives will be achieved. Closed-end fund shares may frequently trade at a discount or premium to their net asset value. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, derivatives risk, liquidity risk, and income risk. As interest rates rise, bond prices fall. Lower credit debt securities may be more likely to fail to make timely interest or principal payments. Leverage increases return volatility and magnifies the Fund’s potential return and its risks; there is no guarantee a fund’s leverage strategy will be successful. These and other risk considerations such as inverse floater risk and tax risk are described in more detail on the Fund’s web page at www.nuveen.com/NVG.
Nuveen Municipal Credit Income Fund (NZF)

Investment Policy Update
While there are no such limits imposed by applicable regulations, certain Nuveen Closed-End Funds formerly had investment policies that placed limits on a Fund’s ability to invest in illiquid securities. All exchange-listed Nuveen Closed-End Funds now have no formal limit on their ability to invest in such illiquid securities, but each Fund’s portfolio management team will monitor such investments in the regular, overall management of the Fund’s portfolio securities.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Trustees of
Nuveen AMT-Free Municipal Credit Income Fund
Nuveen Municipal Credit Income Fund
Nuveen Municipal High Income Opportunity Fund
Nuveen Municipal Credit Opportunities Fund
Opinion on the Financial Statements
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, and Nuveen Municipal Credit Opportunities Fund (the “Funds”), including the portfolios of investments, as of October 31, 2019, the related statements of operations for the year then ended (period from September 16, 2019 (commencement of operations) to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund), the statements of cash flows of Nuveen AMT-Free Municipal Credit Income Fund, Nuveen Municipal Credit Income Fund, and Nuveen Municipal High Income Opportunity Fund for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended (period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit 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 (period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit 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, 2019, the results of their operations for the year then ended (period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund), the cash flows of Nuveen AMT-Free Municipal Credit Income Fund, Nuveen Municipal Credit Income Fund, and Nuveen Municipal High Income Opportunity Fund for the year then ended, the changes in their net assets for each of the years in the two-year period then ended (period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit Opportunities Fund), and the financial highlights for each of the years in the five-year period then ended (period from September 16, 2019 to October 31, 2019 for Nuveen Municipal Credit 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, 2019, 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.

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

NZF | Nuveen Municipal Credit Income Fund Portfolio of Investments (continued) October 31, 2019

(1) | All percentages shown in the Portfolio of Investments are based on net assets applicable to common shares unless otherwise noted.
(2) | Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3) | The ratings disclosed are the lowest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4) | Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(5) | Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(6) | Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.
(7) | Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.
(8) | Effective February 12, 2019, the par value of the original bonds was replaced with taxable and tax exempt Puerto Rico Sales Tax Financing Corporation (commonly known as COFINA) bond units that are collateralized by a bundle of zero and coupon paying bonds. The quantity shown represents units in a trust, which were assigned according to the original bond’s accreted value. These securities do not have a stated coupon interest rate and income will be recognized through accretion of the discount associated with the trust units. The factor at which these units accrete can also decrease, primarily for principal payments generated from coupon payments received or dispositions of the underlying bond collateral. The quantity of units will not change as a result of these principal payments.
(9) | Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 3 – Investment Valuation and Fair Value Measurements for more information.
(10) | A copy of the most recent financial statements for these investment companies can be obtained directly from the Securities and Exchange Commission on its website at http://www.sec.gov.
(11) | MuniFund Preferred Shares, net of deferred offering costs as a percentage of Total Investments is 17.3%.
(12) | Variable Rate Demand Preferred Shares, net of deferred offering costs as a percentage of Total Investments is 19.5%.
144A | Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
ATM | Alternative Minimum Tax.
ETM | Escrowed to maturity.
IF | Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.
PIK | Payment-in-kind (“PIK”) security. Depending on the terms of the security, income may be received in the form of cash, securities, or a combination of both. The PIK rate shown, where applicable, represents the annualized rate of the last PIK payment made by the issuer as of the end of the reporting period.
UB | Underlying bond of an inverse floating rate trust reflected as a financing transaction. See Notes to Financial Statements, Note 4 – Portfolio Securities and Investments in Derivatives, Inverse Floating Rate Securities for more information.

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

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

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

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

• | Nuveen Municipal Credit Income Fund (NZF)

• | Nuveen Municipal High Income Opportunity Fund (NMZ)

• | Nuveen Municipal Credit Opportunities Fund (NMCO)

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 and NMCO were organized as Massachusetts business trusts on July 12, 1999, March 21, 2001, October 8, 2003 and April 18, 2019, respectively.
The end of the reporting period for the Funds is October 31, 2019, and the period covered by these Notes to Financial Statements for NVG, NZF and NMZ is the fiscal year ended October 31, 2019 (the “current fiscal period”). The reporting period for NMCO is the period September 16, 2019 (commencement of operations) through October 31, 2019.
Investment 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
During May 2019, the Funds’ Board of Trustees (the “Board”) approved the merger of the Nuveen Connecticut Quality Municipal Income Fund (NTC) (the “Target Fund”) into NVG (the “Acquiring Fund”) (the “Merger”). The Merger is intended to create one larger fund with lower operating expenses and increased trading volume on the exchange for common shares.
The Merger was approved by shareholders of the Target Fund at a special meeting during October 2019 and was completed before the opening of business on November 18, 2019 (subsequent to the close of this reporting period).
2. Significant Accounting Policies
The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. Each Fund is an investment company and follows the accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services—Investment Companies. The net asset value (“NAV”) for financial reporting purposes may differ from the NAV for processing security and common share transactions. The NAV for financial reporting purposes includes security and common share transactions through the date of the report. Total return is computed based on the NAV used for processing security and common share transactions. The following is a summary of the significant accounting policies consistently followed by the 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 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.
144

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 reflects the amortization of premiums and accretion of discounts for financial reporting purposes and, is recorded on an accrual basis. Investment income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash.
Netting Agreements
In the ordinary course of business, the 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 NMCO on September 16, 2019, 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 NMCO and it did not have a material impact on the Fund’s financial statements. Management is currently evaluating the implications of ASU 2017-18, if any, for NVG, NZF and NMZ.
Fair Value Measurement: Disclosure Framework
During August 2018, the FASB issued ASU 2018-13 (“ASU 2018-13”), Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements. ASU 2018-13 modifies the disclosures required by Topic 820, Fair Value Measurements. The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Management has early implemented this guidance and it did not have a material impact on the Funds’ financial statements.
3. Investment Valuation and Fair Value Measurements
The fair valuation input levels as described below are for fair value measurement purposes.
The Funds’ investments in securities are recorded at their estimated fair value. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the
145

Notes to Financial Statements (continued)
reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.
Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.
Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).
Level 3 – Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).
Prices of fixed income securities are provided by an independent pricing service (“pricing service”) approved by the Board. The pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity, provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs.
Prices of swap contracts are also provided by a pricing service approved by the Board using the same methods as described above and are generally classified as Level 2.
Investments in investment companies are valued at their respective NAV on valuation date and are generally classified as Level 1.
Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1. Securities primarily traded on the Nasdaq National Market (“Nasdaq”) are valued at the Nasdaq Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or Nasdaq for which there were no transactions on a given day or securities not listed on a securities exchange or Nasdaq are valued at the quoted bid price and are generally classified as Level 2.
Exchange-traded funds are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1.
Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Board and/or its appointee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Board and/or its appointee.

4. 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.
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.
147

Notes to Financial Statements (continued)
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 |
Floating rate obligations: self-deposited Inverse Floaters |  | $ | 184,980,000 |  |  | $ | 23,620,000 |  |  | $ | 383,362,000 |  |  | $ | 28,500,000 |
Floating rate obligations: externally-deposited Inverse Floaters |  |  | 77,355,000 |  |  |  | 11,095,000 |  |  |  | 107,065,000 |  |  |  | — |
Total |  | $ | 262,335,000 |  |  | $ | 34,715,000 |  |  | $ | 490,427,000 |  |  | $ | 28,500,000 |

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 |
Average floating rate obligations outstanding |  | $ | 184,864,438 |  |  | $ | 23,620,000 |  |  | $ | 374,332,633 |  |  | $ | 2,345,548 |
Average annual interest rate and fees |  |  | 2.10 | % |  |  | 2.16 | % |  |  | 2.15 | % |  |  | 1.94 | %

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.
As described above, any amounts outstanding under a liquidity facility are recognized as a component of “Floating rate obligations” on the Statement of Assets and Liabilities by the Fund holding the corresponding Inverse Floaters issued by the borrowing TOB Trust. As of the end of the reporting period there were no loans outstanding under any such facility.
148

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 |
Maximum exposure to Recourse Trusts: self-deposited Inverse Floaters |  | $ | 177,235,000 |  |  | $ | 8,775,000 |  |  | $ | 352,922,000 |  |  | $ | 28,500,000 |
Maximum exposure to Recourse Trusts: externally-deposited Inverse Floaters |  |  | 65,000,000 |  |  |  | 9,420,000 |  |  |  | 104,815,000 |  |  |  | — |
Total |  | $ | 242,235,000 |  |  | $ | 18,195,000 |  |  | $ | 457,737,000 |  |  | $ | 28,500,000 |

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 but excluding derivative transactions, where applicable) during the current fiscal period were as follows:

|  | NVG |  |  | NZF |  |  | NMZ |  |  | NMCO |
Purchases |  | $ | 336,191,714 |  |  | $ | 419,425,265 |  |  | $ | 266,237,896 |  |  | $ | 779,041,825 |
Sales and maturities |  |  | 361,090,778 |  |  |  | 486,237,108 |  |  |  | 205,266,707 |  |  |  | 49,666,848 |

Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments 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.
As of the end of the reporting period, the following Funds' outstanding when-issued/delayed delivery purchase commitments were as follows:

|  | NVG |  |  | NMCO |
Outstanding when-issued/delayed delivery purchase commitments |  | $ | 14,126,730 |  |  | $ | 773,672 |

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.
Interest Rate Swap Contracts
Interest rate swap contracts involve a Fund’s agreement with the counterparty to pay or receive a fixed rate payment in exchange for the counterparty receiving or paying a variable rate payment. Forward interest rate swap contracts involve a Fund’s agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying the Fund a variable or fixed rate payment, the accruals for which would begin at a specified date in the future (the “effective date”).
The amount of the payment obligation for an interest rate swap is based on the notional amount and the termination date of the contract. Interest rate swap contracts do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to the swap counterparty on such transactions is limited to the net amount of interest payments that the Fund is to receive.
149

Notes to Financial Statements (continued)
Interest rate swap contracts are valued daily. Upon entering into an interest rate swap contract (and beginning on the effective date for a forward interest rate swap contract), a Fund accrues the fixed rate payment expected to be paid or received and the variable rate payment expected to be received or paid on the interest rate swap contracts on a daily basis, and recognizes the daily change in the fair value of the Fund’s contractual rights and obligations under the contracts. For an over-the-counter (“OTC”) swap that is not cleared through a clearing house (“OTC Uncleared”), the amount recorded on these transactions is recognized on the Statement of Assets and Liabilities as a component of “Unrealized appreciation or depreciation on interest rate swaps.”
Upon the execution of an OTC swap cleared through a clearing house (“OTC Cleared”), the Fund is obligated to deposit cash or eligible securities, also known as “initial margin,” into an account at its clearing broker equal to a specified percentage of the contract amount. Cash deposited by the Fund to cover initial margin requirements on open swap contracts, if any, is recognized as a component of “Cash collateral at brokers for investments in swaps” on the Statement of Assets and Liabilities. Investments in OTC Cleared swaps obligate the Fund and the clearing broker to settle monies on a daily basis representing changes in the prior day’s “mark-to-market” of the swap contract. If the Fund has unrealized appreciation, the clearing broker will credit the Fund’s account with an amount equal to the appreciation. Conversely, if the Fund has unrealized depreciation, the clearing broker will debit the Fund’s account with an amount equal to the depreciation. These daily cash settlements are also known as “variation margin.” Variation margin for OTC Cleared swaps is recognized as a receivable and/or payable for “Variation margin on swap contracts” on the Statement of Assets and Liabilities. Upon the execution of an OTC Uncleared swap, neither the Fund nor the counterparty is required to deposit initial margin as the trades are recorded bilaterally between both parties to the swap contract, and the terms of the variation margin are subject to a predetermined threshold negotiated by the Fund and the counterparty. Variation margin for OTC Uncleared swaps is recognized as a component of “Unrealized appreciation or depreciation on interest rate swaps” as described in the preceding paragraph.
The net amount of periodic payments settled in cash are recognized as a component of “Net realized gain (loss) from swaps” on the Statement of Operations, in addition to the net realized gain or loss recorded upon the termination of the swap contract. For tax purposes, payments expected to be received or paid on the swap contracts are treated as ordinary income or expense, respectively. Changes in the value of the swap contracts during the fiscal period are recognized as a component of “Change in net unrealized appreciation (depreciation) of swaps” on the Statement of Operations. In certain instances, payments are made or received upon entering into the swap contract to compensate for differences between the stated terms of the swap agreements and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). Payments received or made at the beginning of the measurement period, if any, are recognized as “Interest rate swaps premiums received and/or paid” on the Statement of Assets and Liabilities.
During the current fiscal period, NVG continued to invest in forward interest rate swap contracts, as part of its duration management strategies, to help reduce price volatility risk to movements in U.S. interest rates relative to the Fund’s benchmark.
The average notional amount of interest rate swap contracts outstanding during the current fiscal period was as follows:

|  | NVG |
Average notional amount of interest rate swap contracts outstanding* |  | $ | 15,880,000 |

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

The following table presents the amount of net realized gain (loss) and change in net unrealized appreciation (depreciation) recognized on swap contracts on the Statement of Operations during the current fiscal period, and the primary underlying risk exposure.

|  |  |  | Change in Net
|  |  | Net Realized | Unrealized Appreciation
| Underlying | Derivative | Gain (Loss) from | (Depreciation) of
Fund | Risk Exposure | Instrument | Swaps | Swaps
NVG | Interest rate | Swaps | $(80,409) | $(1,924,823)

Market and Counterparty Credit Risk
In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.
Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold.
150

Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.
5. Fund Shares
Common 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 the current 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 |
|  | 10/31/19 |  |  | 10/31/18 |

Offering proceeds, net of offering costs |  | $ | 69,515,572 |  |  | $ | 9,084,815 |

* | Represents additional authorized common shares for the period November 1, 2017 through August 31, 2018.
** | 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
Transactions in common shares for the Funds during the Funds’ current and prior fiscal period, where applicable, were as follows:

Notes to Financial Statements (continued)
Preferred Shares
Adjustable Rate MuniFund Term Preferred Shares
NMZ has issued and has outstanding Adjustable Rate MuniFund Term Preferred (“AMTP”) Shares, with a $100,000 liquidation preference per share. AMTP Shares are issued via private placement and are not publicly available.
The details of NMZ’s AMTP Shares outstanding as of the end of the reporting period, were as follows:

|  |  |  | Liquidation
|  |  |  | Preference
|  |  |  | Net of
|  | Shares | Liquidation | Deferred
Fund | Series | Outstanding | Preference | Offering Costs
NMZ | 2028 | 870 | $87,000,000 | $86,866,271

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

| Notice |  | Term | Premium
Fund | Period | Series | Redemption Date | Expiration Date
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 the Fund during the current fiscal period were as follows:

|  | NMZ |
Average liquidation preference of AMTP Shares outstanding |  | $ | 87,000,000 |
Annualized dividend rate |  |  | 2.39 | %

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 NMZ’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, market value of the MFP Shares is expected to approximate its liquidation preference. Shareholders have the ability to request a best-efforts tender of its shares upon seven days notice. If the remarketing agent is unable to identify an alternative purchaser, the shares will be retained by the share- holder requesting tender and the subsequent dividend rate will increase to its step-up dividend rate. If after one consecutive year of unsuccessful remarketing attempts, the Fund will be required to designate an alternative mode or redeem the shares. Each Fund will pay a remarketing fee on the aggregate principal amount of all MFP Shares while designated in VRRM. Payments made by the Fund to the remarketing agent are recognized as “Remarketing fees” on the Statement of Operations.

• | Variable Rate Mode (“VRM”) – Dividends for MFP Shares designated in this mode are based upon a short-term index plus an additional fixed “spread” amount established at the time of issuance or renewal / conversion of its mode. At the end of the period of the mode, the Fund will be required to either extend the term of the mode, designate an alternative mode or redeem the MFP Shares. The fair value of MFP Shares while in VRM are expected to approximate their liquidation preference so long as the fixed “spread” on the shares remains roughly in line with the “spread” being demanded by investors on instruments having similar terms in the current market. In current market conditions, the Adviser has determined that the fair value of the shares are approximately their liquidation preference, but their fair value could vary if market conditions change materially.

• | Variable Rate Demand Mode (“VRDM”) – Dividends for MFP Shares designated in this mode will be established by a remarketing agent; therefore, the market value of the MFP Shares is expected to approximate its liquidation preference. While in this mode, Shares will have an unconditional liquidity feature that enable its shareholders to require a liquidity provider, which the Fund has entered into a contractual agreement, to purchase shares in the event that the shares are not able to be successfully remarketed. In the event that shares within this mode are unable to be successfully remarketed and are purchased by the liquidity provider, the dividend rate will be the maximum rate which is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the shares. Each Fund is required to redeem any shares that are still owned by a liquidity provider after six months of continuous, unsuccessful remarketing. The Fund will pay a liquidity and remarketing fee on the aggregate principal amount of all MFP shares while within VRDM. Payments made by the Fund to the liquidity provider and remarketing agent are recognized as “Liquidity fees” and “Remarketing fees”, respectively, on the Statement 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.
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.
NVG incurred offering costs of $1,540,000 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.
In conjunction with NVG’s redemption of MFP Shares, deferred costs of $171,958 were expensed during the current fiscal period, as the redemption was deemed an extinguishment of debt.
As of the end of the reporting period, NVG and NZF had $403,797,156 and $639,973,963 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 $1,407,881,715 and $722,295,855 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:

* | 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.
NZF’s Series 1 and Series 2 VRDP Shares are considered to be Special Rate VRDP, which are sold to institutional investors. The special rate period will expire on March 1, 2040 for the Fund’s Series 1 and 2 VRDP Shares, but is subject to earlier termination by either the Fund or the holder. During the special rate period, the VRDP Shares will not be remarketed by a remarketing agent, be subject to optional or mandatory tender events, or be supported by a liquidity provider and are not subject to remarketing fees or liquidity fees. During the special rate period, VRDP dividends will be set monthly as a floating rate based on the predetermined formula. Following the initial special rate period, Special Rate Period VRDP Shares may transition to traditional VRDP Shares with dividends set at weekly remarketings, and be supported by designated liquidity provider, or the Board may approve a subsequent special rate period.
Dividends on the VRDP Shares (which are treated as interest payments for financial reporting purposes) are set at a rate established by a remarketing agent; therefore, the market value of the VRDP Shares is expected to approximate its liquidation preference. In the event that VRDP Shares are unable to be successfully remarketed, the dividend rate will be the maximum rate which is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the VRDP Shares.
Subject to certain conditions, VRDP Shares may be redeemed, in whole or in part, at any time at the option of each Fund. Each Fund may also redeem certain of the VRDP Shares if the Fund fails to maintain certain asset coverage requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation preference per share plus any accumulated but unpaid dividends.

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

|  | NVG |  |  | NZF |
Average liquidation preference of VRDP Shares outstanding |  | $ | 1,411,600,000 |  |  | $ | 727,000,000 |
Annualized dividend rate |  |  | 1.69 | % |  |  | 2.36 | %

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.

Notes to Financial Statements (continued)
6. 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, 2019.

|  | NVG |  |  | NZF |  |  | NMZ |  |  | NMCO |
Tax cost of investments |  | $ | 4,641,264,395 |  |  | $ | 3,295,006,390 |  |  | $ | 939,725,116 |  |  | $ | 795,115,454 |

Permanent differences, primarily due to federal taxes paid, nondeductible offering costs, taxable market discount, and distribution reallocations, resulted in reclassifications among the Funds’ components of common share net assets as of October 31, 2019, 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, 2019, the Funds’ tax year end, were as follows:

|  | NVG |  |  | NZF |  |  | NMZ |  |  | NMCO |
Undistributed net tax-exempt income1 |  | $ | 805,374 |  |  | $ | — |  |  | $ | 8,938,892 |  |  | $ | 2,103,978 |

Undistributed net long-term capital gains |  |  | 7,412,763 |  |  |  | — |  |  |  | — |  |  |  | — |

1 | Undistributed net tax-exempt income (on a tax basis) has not been reduced for the dividend declared on October 1, 2019 and paid on November 1, 2019.
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, 2019 and October 31, 2018 was designated for purposes of the dividends paid deduction as follows:

2 | Net ordinary income consists of taxable market discount income and net short-term capital gains, if any.
3 | The Funds hereby designate these amounts paid during the fiscal year ended October 31, 2019, as Exempt Interest Dividends.
4 | The Funds hereby designate as long-term capital gain dividend, pursuant to the Internal Revenue Code Section 852(b)(3), the amount necessary to reduce earnings and profits of the Funds related to net capital gain to zero for the year ended October 31, 2019.

7. 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 |

157

Notes to Financial Statements (continued)
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 Fund’s 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, 2019, the complex-level fee for each Fund was 0.1566%.

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

Inter-Fund Trades |  | NZF |  |  | NMZ |  |  | NMCO |
Purchases |  | $ | — |  |  | $ | — |  |  | $ | 3,228,540 |
Sales |  |  | 19,368,199 |  |  |  | 19,939,437 |  |  |  | — |

The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, $2.65 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for various purposes other than leveraging for investment purposes. Each Participating Fund is allocated a designated proportion of the facility’s capacity (and its associated costs, as described below) based upon a multi-factor assessment of the likelihood and frequency of its need to draw on the facility, the size of the Fund and its anticipated draws, and the potential importance of such draws to the operations and well-being of the Fund, relative to those of the other Funds. A Fund may effect draws on the facility in excess of its designated capacity if and to the extent that other Participating Funds have undrawn capacity. The credit facility expires in June 2020 unless extended or renewed.
The credit facility has the following terms: a fee of 0.15% per annum on unused commitment amounts, and interest at a rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.00% per annum or (b) the Fed Funds rate plus 1.00% per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Other expenses” on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund.
158

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 | $21,500,000 | $35,500,000 | $19,700,000

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) | 63 | 107 | 38
Average daily balance outstanding | $12,581,651 | $13,550,459 | $14,531,579
Average annual interest rate | 3.34% | 3.39% | 3.49%

Borrowings outstanding as of the end of the reporting period are recognized as “Borrowings” on the Statement of Assets and Liabilities, where applicable.
Inter-Fund Borrowing and Lending
The 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.
9. Subsequent Events
Fund Merger
As noted in Note 1 – General Information, Fund Merger, before the opening of business on November 18, 2019 NTC merged into NVG.

Glossary of Terms Used in this Report (Unaudited)

■ | Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumula- tive 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.

■ | Forward Interest Rate Swap: A contractual agreement between two counterparties under which one party agrees to make peri- odic payments to the other for an agreed period of time based on a fixed rate, while the other party agrees to make periodic payments based on a floating rate of interest based on an underlying index. Alternatively, both series of cash flows to be exchanged could be calculated using floating rates of interest but floating rates that are based upon different underlying indexes.

■ | 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.

162

■ | 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 perform- ance 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.

■ | 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 govern- ments 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.

■ | The 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 resid- ual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.

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

Reinvest Automatically, Easily and Conveniently
Nuveen makes reinvesting easy. A phone call is all it takes to set up your reinvestment account.

Nuveen Closed-End Funds Automatic Reinvestment Plan
Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares. By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.
Easy and convenient
To make recordkeeping easy and convenient, each month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.
How shares are purchased
The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value on the last business day immediately prior to the purchase date. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.
Flexible
You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change. You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan. The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

Annual Investment Management Agreement Approval Process (Unaudited)
The Board of Trustees (each, a “Board,” and each Trustee, a “Board Member”) of each Fund, 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”), is responsible for determining whether to initially approve or, after an initial term, to renew, the advisory arrangements of its respective Fund. A discussion of the Board’s most recent approval of the renewal of the advisory arrangements for each Fund other than Nuveen Municipal Credit Opportunities Fund is set forth in Part I below. The advisory arrangements for Nuveen Municipal Credit Opportunities Fund have not yet been up for renewal. A discussion of the Board’s initial approval of the advisory arrangements for Nuveen Municipal Credit 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 21-23, 2019 (the “May Meeting”), the Board of each Fund (as defined below), including the Independent Board Members, approved, for its respective Fund, 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 sub-adviser to such Fund. For purposes of this Part I, the following are the “Funds”: Nuveen AMT-Free Municipal Credit Income Fund (the “AMT-Free Municipal Credit Fund”); Nuveen Municipal Credit Income Fund (the “Municipal Credit Fund”); and Nuveen Municipal High Income Opportunity Fund (the “Municipal High Income Fund”). Following an initial two-year period, the Board, including the Independent Board Members, is required under the 1940 Act to review and approve 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.”
In response to a request on behalf of the Independent Board Members by independent legal counsel, the Board received and reviewed prior to the May Meeting extensive materials specifically prepared for the annual review of Advisory Agreements by the Adviser as well as by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials provided in connection with the annual review covered a breadth of subject matter including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of the Sub-Adviser and investment team; 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-Adviser; and a description of indirect benefits received by the Fund Advisers as a result of their relationships with the Nuveen funds. The Board Members held an in-person meeting on April 17-18, 2019 (the “April Meeting”), in part, to review
165

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
and discuss the performance of the Nuveen funds and the Adviser’s evaluation of the various sub-advisers to the Nuveen funds. The Independent Board Members asked questions and requested additional information that was provided for the May Meeting.
The information prepared specifically for the annual review of the Advisory Agreements supplemented the information provided to the Board and its committees throughout the year. The Board and its committees met regularly during the year and the information provided and topics discussed were relevant to the review of the Advisory Agreements. Some of these reports and other data included, among other things, materials that outlined the investment performance of the Nuveen funds; strategic plans of the Adviser which may impact the services it provides to the Nuveen funds; the review of the Nuveen funds and applicable investment teams; the management of leverage financing for closed-end funds; the secondary market trading of the closed-end funds and any actions to address discounts; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers; valuation of securities; fund expenses; and overall market and regulatory developments. The Board further 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 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 Fund 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.
In deciding to renew the Advisory Agreements, the Independent Board Members did not identify a particular factor or information as determinative or controlling, but rather the decision reflected the comprehensive consideration of all the information provided, and each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the approval process. The following summarizes the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements and its conclusions.
A. Nature, Extent and Quality of Services
In evaluating the renewal of the Advisory Agreements, the Independent Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to the respective Fund with particular focus on the services and enhancements to such services provided during the last year. The Board recognized that the Adviser provides a comprehensive set of services necessary to operate the Nuveen funds in a highly regulated industry and noted that the scope of such services has expanded over the years as a result of regulatory, market and other developments, such as the development of the liquidity management program and expanded compliance programs. Some of the functions the Adviser is responsible for include, but are not limited to: product management (such as analyzing a fund’s position in the marketplace, setting dividends, preparing shareholder and intermediary communications and other due diligence support); investment oversight (such as analyzing fund performance, sub-advisers and investment teams and analyzing trade executions of portfolio transactions, soft dollar practices and securities lending activities); securities valuation services (such as executing the daily valuation process for portfolio securities and developing and recommending changes to valuation policies and procedures); risk management (such as overseeing operational and investment risks, including stress testing); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the Nuveen 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 oversight and liaison of transfer agent service providers which include registered shareholder customer service and transaction processing); Board relations services
166

(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 developing and maintaining a compliance program to ensure compliance with applicable laws and regulations, monitoring compliance with applicable fund policies and procedures and adherence to investment restrictions, and evaluating the compliance programs of the Nuveen fund sub-advisers and certain other service providers); legal support and oversight of outside law firms (such as with respect to filing and updating registration statements; maintaining various regulatory registrations; and providing legal interpretations regarding fund activities, applicable regulations and implementation of policies and procedures); and leverage, capital and distribution management services. In reviewing the scope and quality of services, the Board recognized the continued efforts and resources the Adviser and its affiliates have employed to continue to enhance their services for the benefit of the complex as well as particular Nuveen funds over recent years. Such service enhancements have included, but are 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, repositioning funds, merging funds, reviewing and updating investment policies and benchmarks, modifying the composition of certain portfolio management teams and analyzing various data to help devise such improvements;

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

| ● | Compliance Program Initiatives – continuing efforts to enhance the compliance program through, among other things, internally integrating various portfolio management teams and aligning compliance support accordingly, completing a comprehensive review of existing policies and procedures and revising such policies and procedures as appropriate, enhancing compliance-related technologies and workflows, and optimizing compliance shared services across the organization and affiliates;

| ● | Risk Management and Valuation Services - continuing efforts to strengthen the risk management functions, including through, among other things, enhancing the interaction and reporting between the investment risk management team and various affiliates, increasing the efficiency of risk monitoring performed on the Nuveen funds through improved reporting, continuing to implement risk programs designed to provide a more disciplined and consistent approach to identifying and mitigating operational risks, continuing progress on implementing a liquidity program that complies with the new liquidity regulatory requirements and continuing to oversee the daily valuation process;

| ● | Additional Compliance Services – continuing investment of time and resources necessary to develop the compliance policies and procedures and other related tools necessary to meet the various new regulatory requirements affecting the Nuveen funds that have been adopted over recent years;

| ● | Government Relations – continuing efforts of various Nuveen teams and affiliates to advocate and communicate their positions with lawmakers and other regulatory bodies on issues that will impact the Nuveen funds;

| ● | Business Continuity, Disaster Recovery and Information Services – establishing an information security program to help identify and manage information security risks, periodically testing disaster recovery plans, maintaining and updating business continuity plans and providing reports to the Board, at least annually, addressing, among other things, management’s security risk assessment, cyber risk profile, incident tracking and other relevant information technology risk-related reports;

| ● | Expanded Dividend Management Services – continuing to expand the services necessary to manage the dividends among the varying types of Nuveen funds that have developed as the Nuveen complex has grown in size and scope; 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, refinancing existing leverage and negotiating reductions in associated leverage expenses;

167

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

| ●● | Capital Management Services – ongoing capital management efforts through a share repurchase program as well as a shelf offering program that raises additional equity capital in seeking to enhance shareholder value;

| ●● | Data and Market Analytics – continuing focus on analyzing data and market analytics to better understand the ownership cycles and secondary market experience of closed-end funds; 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.

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. The Board noted that the Adviser oversees the Sub-Adviser and 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 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 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 the investment performance of the Nuveen funds they advise. In this regard, the Board reviewed Fund performance over the quarter, one-, three- and five-year periods ending December 31, 2018 as well as performance data for the first quarter of 2019 ending March 29, 2019. Unless otherwise indicated, the performance data referenced below reflects the periods ended December 31, 2018. The Board considered the Adviser’s analysis of each fund’s performance, with particular focus on funds that were considered performance outliers and the factors contributing to their performance. The Board also noted that it received performance data of the Nuveen funds during its quarterly meetings throughout the year and took into account the discussions that occurred at these Board meetings regarding fund performance. In this regard, in its evaluation of Nuveen fund performance at meetings throughout the year, the Board considered performance information for the funds for different time periods, both absolute and relative to appropriate benchmarks and peers, with particular attention to information indicating underperformance of the respective funds and discussed with the Adviser the reasons for such underperformance.
The Board reviewed both absolute and relative fund performance during the annual review. 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). 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) 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. Depending on the facts and circumstances, however, 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. In addition, the performance data may vary significantly depending on the end date selected, and shareholders may evaluate fund performance based on their own holding period which may differ
168

from the performance periods reviewed by the Board leading to different results. Further, the Board considered a fund’s performance in light of the overall financial market conditions during the respective periods. As noted above, the Board reviewed, among other things, Nuveen fund performance over various periods ended December 31, 2018, and the Board was aware of the market decline in the fourth quarter of 2018 and considered performance from the first quarter of 2019 as well. The Board also noted that a shorter period of underperformance may significantly impact longer term performance.
In addition to the foregoing, the Board recognized the importance of secondary market trading to shareholders and considered the evaluation of premiums and discounts at which the shares of the Nuveen closed-end funds trade to be a continuing priority for the Board. The Board and/or its Closed-end Fund committee consider premium and discount data at each quarterly meeting throughout the year as well as during the annual review.
In their review of performance, the Independent Board Members focused, in particular, on the Adviser’s analysis of Nuveen funds determined to be underperforming performance outliers. The Board recognized that some periods of underperformance may only be temporary while other periods of underperformance may indicate a broader issue that may require a corrective action. Accordingly, 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 Fund, the Board noted that the Fund ranked in the second quartile of its Performance Peer Group for the one-year period and first quartile for the three- and five-year periods. In its review, the Board, however, noted that the Performance Peer Group was classified as low for relevancy. In addition, although the Fund’s performance was below the performance of its blended benchmark for the one-year period, the Fund outperformed its blended benchmark for the three-and five-year periods. The Board was satisfied with the Fund’s overall performance.
For the Municipal Credit Fund, the Board noted that the Fund ranked in the second quartile of its Performance Peer Group for the one-year period and first quartile for the three- and five-year periods. In its review, the Board, however, noted that the Performance Peer Group was classified as low for relevancy. In addition, although the Fund’s performance was below the performance of its blended benchmark for the one-year period, the Fund outperformed its blended benchmark for the three-and five-year periods. The Board was satisfied with the Fund’s overall performance.
For the Municipal High Income Fund, the Board noted that although the Fund ranked in the fourth quartile of its Performance Peer Group for the one-year period, the Fund ranked in the first quartile for the three- and five-year periods. In addition, although the Fund’s performance was below the performance of its benchmark for the one- and three-year periods, the Fund outperformed its benchmark for the five-year period. The Board was satisfied with the Fund’s overall performance.
C. Fees, Expenses and Profitability
1. Fees and Expenses
In its annual review, the Board considered the fees paid to the Fund Advisers and the total operating expense ratio of each Nuveen fund. More specifically, the Independent Board Members reviewed, among other things, each fund’s gross and net management fee rates 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.
169

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
In their review, the Independent Board Members considered, in particular, each fund with a net expense ratio (excluding investment-related costs of leverage) of six basis points or higher compared to that of its peer average (each, an “Expense Outlier Fund”), including the Municipal Credit 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 the Nuveen 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, as applicable. The Board noted that across the Nuveen fund complex, the complex-wide fee breakpoints reduced fees by $51.5 million and fund-level breakpoints reduced fees by $55.1 million in 2018.
With respect to the Sub-Adviser, the Board considered the sub-advisory fee paid to the Sub-Adviser, including any breakpoint schedule, and as described below, comparative data of the fees the Sub-Adviser charges to other clients, if any.
The Independent Board Members noted that: (a) the AMT-Free Municipal Credit Fund and the Municipal High Income Fund each had a net management fee higher than its peer average, but a net expense ratio in line with its peer average; and (b) the Municipal Credit Fund had a net management fee higher than its peer average and a net expense ratio slightly higher than its peer average. The Independent Board Members noted that the Municipal Credit Fund’s net expense ratio increased in 2018 as a result of increased management fees resulting from an increase in leverage for such Fund. Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.
2. Comparisons with the Fees of Other Clients
In determining the appropriateness of fees, the Board also reviewed 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 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 addition to the comparative fee data, the Board 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 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 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
170

concluded the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.
3. Profitability of Fund Advisers
In conjunction with their review of fees, the Independent Board Members 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 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 adjusted 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 exchange-traded fund product line that was launched in 2016. The Independent Board Members 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 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 also noted that Nuveen’s adjusted 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 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.
The Independent Board Members also reviewed a description of the expense allocation methodology employed to develop the financial information and a summary of the history of changes to the methodology over the ten-year period from 2008 to 2018, and recognized that other reasonable allocation methodologies could be employed and lead to significantly different results. The Board noted that two Independent Board Members, along with independent counsel, serve as the Board’s liaisons to review profitability and discuss any proposed changes to the methodology prior to the full Board’s review.
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 2018 and 2017 calendar years to consider the financial strength of TIAA having recognized the importance of having an adviser with significant resources.
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 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 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 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.
171

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale
With respect to economies of scale, the Independent Board Members noted that although economies of scale are difficult to measure, the Adviser shares the benefits of economies of scale in various ways including breakpoints in the management fee schedule (subject to limited exceptions), fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in its business which can enhance the services provided to the funds for the fees paid. With respect to breakpoint schedules, because the Board had 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. The Independent Board Members reviewed, among other things, the fund-level and complex-level fee schedules. In addition, with respect to the Nuveen closed-end funds, the Independent Board Members 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.
In addition, the Independent Board Members 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 its review, the Board concluded that the current fee arrangements together with the Adviser’s reinvestment in its business appropriately shared any economies of scale with shareholders.
E. Indirect Benefits
The Independent Board Members received and considered information regarding other benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the Nuveen funds. The Board considered 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, the Independent Board Members also 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, 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 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 resources, the research may also benefit the Nuveen funds to the extent it enhances the ability of the Sub-Adviser to manage such funds or is acquired through the commissions paid on portfolio transactions of other clients.
Based on their review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the 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.
172

PART II
Nuveen Municipal Credit Opportunities Fund
At a meeting held on May 21-23, 2019 (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 Municipal Credit 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;

● | 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 all 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
173

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
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.
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 anticipated investment strategy would have some similarities to that of the Nuveen High Yield Municipal Bond Fund (the “High Yield Fund”), a Nuveen open-end fund which had an inception date of June 7, 1999. In this regard, the Independent Board Members reviewed certain performance information relating to the High Yield Fund, including average annual total returns for the quarter-to-date, year-to-date, one-year, three-year, five-year, ten-year and since inception periods as of March 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 that of Nuveen Municipal High Income Opportunity Fund (NMZ), another comparable closed-end fund in the Nuveen family of funds, and the corresponding differences in management fee rates between the funds. Further, the Independent Board Members took into account the proposed sub-advisory fee for the Fund.
174

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.
2. 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.
3. 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
175

Annual Investment Management Agreement Approval Process (Unaudited) (continued)
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 adjusted 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 adjusted 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.
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
176

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 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.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.
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 BIOGRAPHY
As of the date of filing this report, the following individual had primary responsibility for the
day-to-day implementation of the registrant’s investment strategies:
Paul Brennan, CFA, CPA, manages several Nuveen municipal national and state mutual funds and closed-end bond funds. 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 THE PORTFOLIO MANAGER
Other Accounts Managed. In addition to managing the registrant, 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 | $17.91 billion
| Other Pooled Investment Vehicles | 1 | $40.28 million
| Other Accounts | 2 | $53.75 million

* | Assets are as of October 31, 2019. 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, 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.
