Chair’s Letter to Shareholders


Dear Shareholders,
The COVID-19 crisis is taking an unprecedented toll on our health, societies, economies and financial markets. Our thoughts are with all whose lives have been affected by the disease and its economic fallout. With some regions of the world having appeared to “flatten the curve” of infections, governments and public health officials are now facing the extraordinary challenge of balancing the resumption of economic activity with public safety, in a way that minimizes the potential for a second wave of outbreaks. Markets have turned their focus to the potential for an economic recovery – the timing and magnitude of which remain highly uncertain. Elevated market volatility is likely to continue, with economic data, coronavirus infection rates and the upcoming U.S. presidential election under scrutiny.
While we do not want to understate the dampening effect on the global economy, it is important to differentiate short-term interruptions from the longer-lasting implications to the economy. Some areas of the global economy were already on the mend prior to the coronavirus epidemic. Temporary bans on movement and travel are being lifted, and some near-term economic indicators have shown modest improvement in countries that have reopened. Central banks and governments around the world have announced economic stimulus measures and pledged to continue doing what it takes to support their economies. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. Government has approved three relief packages, including a $2 trillion-dollar package directly supporting businesses and individuals. The Coronavirus Aid, Relief and Economic Security Act, called the CARES Act, provides direct payments and expanded unemployment benefits to individuals, loans and grants to small businesses, loans and other money to large corporations and funding for hospitals, public health, education and state and local governments.
In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial professional, who can review your time horizon, risk tolerance and investment goals. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.
Sincerely,


Terence J. Toth
Chair of the Board

Portfolio Managers’ Comments


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)
These Funds feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen Fund Advisors, LLC, the Funds’ investment adviser. Portfolio managers John V. Miller, CFA, Steve M. Hlavin, Paul L. Brennan, CFA, Scott R. Romans, PhD and discuss key investment strategies and the six-month performance of the Funds. 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 in 2019.
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.
An Update on COVID-19 Coronavirus and its Impact on the Securities Markets
With daily new COVID-19 coronavirus cases now slowing across much of the world, economies are beginning to reopen and movement bans are easing. The focus is shifting to whether the resumption of activity triggers a second wave of infections and how quickly economies may rebound. Early indications, first from China, South Korea and Hong Kong, and more recently from various U.S. states that opened their economies earlier and more thoroughly than others, showed there is a risk of new infection outbreaks. Economic indicators have begun to reflect the severe supply and demand disruptions resulting from the shutdowns, and a more prolonged recovery looks more likely than a rapid snap-back to growth.
Although the detection of the virus in China was made public in December 2019, markets did not start to fully acknowledge the risks and potential economic impact until the latter portion of February 2020, when outbreaks outside of China were first reported. Global stock markets sold off severely, with the S&P 500® index reaching a bear market (a 20% drop from the previous high) within three weeks, the fastest bear market decline in history. Even certain parts of the bond market suffered; below investment grade municipal and corporate bonds generally dropped the furthest, mostly out of concerns for the continued financial stability of lower quality issuers. Demand for safe-haven assets, along with mounting recession fears, drove the yield on the 10-year U.S. Treasury note to 0.5% in March 2020, an all-time low. Additionally, oil prices collapsed to an 18-year low on supply glut concerns, as shutdowns across the global economy sharply reduced oil demand, although oil prices have recovered to well above those lows.

Portfolio Managers’ Comments (continued)
Central banks and governments have responded with liquidity injections to ease the strain on financial systems and stimulus measures to buffer the shock to businesses and consumers. These measures have helped stabilize the markets over the short term, and most markets have recovered most of their losses. But volatility will likely remain elevated until the health crisis itself is under control (via fewer new cases, lower infection rates and/or verified treatments or vaccines). There are still many unknowns and new information is incoming daily, compounding the difficulty of modeling outcomes for epidemiologists and economists alike.
Nuveen, LLC and our portfolio management teams are monitoring the situation carefully and continuously refining our views and approaches to managing the Funds to best pursue investment objectives while mitigating risks through all market environments.
What key strategies were used to manage the Funds during the six-month reporting period ended April 30, 2020, and how did these strategies influence performance?
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.
For most of the reporting period, a favorable macroeconomic backdrop, strong demand, narrowing credit spreads and falling interest rates supported municipal bond performance. However, the coronavirus pandemic and the shutdown of the economy introduced significant uncertainty about the future of economic growth and impact to municipal credit fundamentals. As the nearer-term impacts began to materialize, we looked for relative value and income enhancement opportunities among credits we believe may demonstrate resilience over the long term.
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. Up until the COVID-19 crisis related market turmoil in late February 2020, most of the Funds’ trading was driven by reinvesting the proceeds from called and maturing bonds. One of the notable transactions during this reporting period was the state of Ohio refunding its legacy Buckeye Tobacco Settlement bonds and issuing new replacement bonds. All four Funds owned the legacy bonds and bought some of the replacement bonds.
In the market sell-off in March 2020, municipal bond credit spreads increased considerably, especially for the lower quality market segments in which NMZ and NMCO concentrate their investments. This turned our focus in March and April 2020 to selling depreciated bonds with lower embedded yields to buy similar structures offering higher embedded yields. This exchanging strategy allows the Funds to take advantage of tax efficiencies and enhance the Funds’ income earnings capability to support the dividend. The volatility in the latter months of the reporting period marginally lengthened the Funds’ (and benchmark index’s) overall duration. As yields rose and credit spreads widened, bonds previously priced to shorter call dates become less likely to be called early, lengthening their duration profile.
Also during this reporting period, the four Funds received Energy Harbor common stock, after FirstEnergy Solutions successfully emerged from bankruptcy and the restructured company was renamed Energy Harbor. The Funds received Energy Harbor stock when their holding of bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of its debt reorganization and emergence from bankruptcy protection, which was completed in February 2020. Over time, we expect to sell these shares and reinvest the proceeds into municipal bonds.
Trading activity was relatively light in NVG. Entering the reporting period, we were comfortable with the Fund’s positioning and there were fewer opportunities to source attractive bonds in the prevailing market conditions. In addition to the Buckeye Tobacco Settlement bonds being called and replaced with the new issue, we added selectively to health care, housing and a few other credits. NVG also held Metropolitan Pier and Exposition Authority at McCormick bonds that were refunded during the reporting period, and we bought the replacement bonds. We took some small precautionary steps to prepare for the possibility of deleveraging, including delaying the reinvestment of cash proceeds from called bonds and coupon income. However, market liquidity, although stressed, remains sufficient and deleveraging was not needed. Overall, NVG’s positioning was relatively stable over this reporting period. The Fund’s duration drifted marginally higher, although it remained well within its duration target range. This was due to the market volatility, some defensive selling of shorter duration bonds and refunded bonds being reinvested into longer duration credits. Relative to the benchmark index, NVG began the reporting period with slightly shorter duration and ended the reporting period roughly neutral to the benchmark.

In NZF, we bought some mid-grade (AA and A rated) hospital and airport bonds, as well as added to Puerto Rico sales tax revenue bonds (known as COFINAs), in the earlier months of the reporting period. In the last six weeks of the reporting period, our focus was on one-on-one bond exchanges, particularly among lower rated airport and health care bonds, as well as Metropolitan Transit Authority (New York) credits. We also added to lower rated positions and participated in the Buckeye Tobacco Settlement new issue after the legacy bonds were called. NZF’s portfolio duration lengthened incrementally due to market volatility and trading activity, rather than any change to our investment philosophy.
For most of the reporting period, NMZ worked to reinvest coupon income, call proceeds and sinking fund (a fund formed by periodically setting aside money for the gradual repayment of a debt) payments. As high yield municipal bond spreads widened significantly beyond their long-term average in the March 2020 sell-off, the market offered a more attractive selection of bonds to choose from. We sold some positions that had held up well during the turbulence, such as pre-refunded bonds and certain Puerto Rico positions, and used the proceeds to buy bonds across a range of issuers and sectors that we believed to be more beaten-up than their fundamentals warranted. Virgin Trains USA Passenger Rail Project, community development districts, Illinois general obligation bonds (GOs), tobacco settlement (including Buckeye Tobacco), charter schools and airline bonds secured by airport facilities (for example, Denver Special Facilities United Airlines and Tulsa Municipal Airport Trust American Airlines) were among those purchases. We also made some one-for-one bond exchanges, notably in NMZ’s COFINA bonds, to maintain the overall exposure to COFINAs while enhancing the embedded yield.
NMCO’s trading was very active, as the invest-up period (from September 2019 through March 2020) spanned most of this reporting period. By the end of the reporting period, the Fund was fully invested, and the credit quality allocation now reflects the Fund’s long-term high yield focus, with most of the portfolio invested in bonds rated BBB and lower. In addition to purchases, we sold a meaningful amount of bonds, as we rolled the portfolio out of higher credit quality bonds that were used as temporary placeholders and bought long-term positions in lower rated and higher yielding bonds. Like the other three Funds, NMCO also looked for opportunities after the sell-off to exchange bonds one-for-one to enhance embedded yields to support its dividend income capability. Similarily, NMCO’s duration drifted modestly higher over the course of the reporting period due to market price declines.
Additionally, at the end of March 2020, NMCO delevered to help mitigate net asset value volatility and manage the leverage ratio within the stated target. These efforts influenced the timing and size of the Fund’s distribution cut. Under normal market conditions, portfolio managers would be able to take mitigating steps, through tax loss bond exchanges and other strategies, to offset the impact of unwinding leverage. However, due to the unprecedented velocity of the market’s sell-off and the compressed time period in which it occurred, we believe it was in the best long-term interest of our shareholders to take these prudent actions in the short term. We believe this can ultimately help enhance earnings over the long run.
As of April 30, 2020, the Funds continued to use inverse floating rate securities. We employ inverse floaters for a variety of reasons, including duration management and income and total return enhancement.
How did the Funds perform during the six-month reporting period ended April 30, 2020?
The tables in each Fund’s Performance Overview and Holding Summaries section of this report provide the Funds’ total returns for the six-month, one-year, five-year, ten-year and since inception periods ended April 30, 2020. Each Fund’s total returns at net asset value (NAV) are compared with the performance of a corresponding market index.
For the six months ended April 30, 2020, the total returns at NAV for NVG, NZF and NMZ underperformed the return for the national S&P Municipal Bond Index. NVG and NZF underperformed the return for the secondary benchmark (composed of 60% S&P Municipal Bond Investment Grade Index and 40% S&P Municipal Bond High Yield Index), and NMZ and NMCO underperformed the return on the S&P Municipal Yield Index.
The main factors influencing the Funds’ relative performance in this reporting period were yield curve and duration positioning, credit quality allocation and sector allocation. In addition, the use of regulatory leverage was an important factor affecting performance of the Funds. Leverage is discussed in more detail later in the Fund Leverage section of this report.
The Funds’ duration and yield curve positioning was disadvantageous in this reporting period. The municipal yield curve steepened, with yields on the short end of the curve falling and yields on the longer end of the curve increasing. The Funds’ overweight allocations to the longer end of the yield curve detracted from relative performance, as longer maturity bonds underperformed.

Portfolio Managers’ Comments (continued)
The main drag on relative performance for all four Funds came from the disproportionate credit spread widening among lower rated and high yield bonds during March 2020. The Funds’ substantial weights to bonds rated BBB and lower (including high yield and non-rated bonds) increased their sensitivity to the dramatic spread widening that occurred during the sell-off. NVG and NZF hold more than 50% of their portfolios and NMZ holds nearly two thirds of its portfolio in BBB rated, high yield (below investment grade) and non-rated credits. NMCO, by the end of the invest-up period, held nearly all of its portfolio in BBB and lower rated bonds. We should note that prior to the COVID-19 crisis, NMCO still had roughly 20% of its portfolio in BBB rated bonds, which served as short-term placeholders to keep the Fund fully invested during the invest-up period. We were able to sell these lower rated investment grade positions and reinvest the proceeds in longer term, higher yielding positions at more attractive spread levels, which accrues to the income earnings and total returns over time.
Sector performance was driven largely by credit ratings, due to the significant spread widening in the latter months of the reporting period. Not surprisingly, the sectors perceived to be most affected by the COVID-19 crisis and its economic aftershocks were among the weakest performing, including transportation, certain higher education institutions, sales tax revenue (especially convention, hotel occupancy and tourist-related sales taxes) and senior living/life care facilities and continuing care retirement communities (CCRCs). Other bonds that were disproportionately affected by the March 2020 sell-off, and therefore underperformed for the reporting period overall, included Illinois and Chicago GOs and U.S. territory debt. For these issuers, investors worried that credit concerns pre-dating the health crisis could be exacerbated by the uncertain outlook. The Funds’ exposure to Illinois and Chicago-related bonds detracted from performance, as did Puerto Rico paper, although to a lesser extent given the small position sizes of the Funds’ Puerto Rico holdings. NMZ and NMCO also held small positions in U.S. Virgin Islands bonds, which also underperformed but with minimal relative performance impact. In addition, the four Funds held tobacco settlement bonds, which did well earlier in the reporting period due to the strong performance of legacy Buckeye Tobacco Settlement bonds. However, those bonds were refunded, and the new issue replacement bond subsequently performed poorly when liquidity became severely stressed in the marketplace in March 2020. Buckeye Tobacco bonds are among the most liquid lower rated, higher yielding bonds, and therefore among the most heavily sold during liquidity-driven events like that of March 2020.
For the Funds individually, NVG’s Illinois and Chicago bonds were among the weakest performers during the reporting period. Metropolitan Pier and Exposition Authority at McCormick, which are backed by hotel occupancy and other sales taxes as well as indirect support from the state of Illinois, were hurt by the shutdown of tourism and the state’s weakened credit outlook. NVG’s position in state of New Jersey appropriation-backed debt also suffered from an uncertain outlook. New Jersey’s credit rating is the second lowest, after Illinois. Lower rated higher education bonds, certain toll road names and industrial development revenue (IDR) bonds such as real estate-backed projects and refineries also detracted from NVG’s performance overall. However, we would point out that FirstEnergy Solutions (renamed Energy Harbor) was an IDR bond that performed relatively well as the company reached a successful bankruptcy outcome. Other positive performers for NVG included pre-refunded bonds, the best performing sector in the market, as well as high credit quality private universities such as Stanford and Massachusetts Institute of Technology and housing bonds. Nearly all of the housing bonds in NVG are high credit quality and we believe are well positioned to weather the pandemic. We added a few names to the portfolio during the reporting period, but the housing position remains relatively small overall.
For NZF, sector allocation in aggregate was a positive offset to the negative impacts of credit quality and duration positioning but had a muted impact on overall relative performance. A small overweight to pre-refunded bonds was beneficial. NZF’s overweight to Illinois and Chicago bonds was a drag on performance, but the weakness was in line with other BBB rated bonds.
NMZ’s performance, which is primarily compared to the S&P Municipal Yield Index, continued to be driven by our bottom-up credit selection. In this reporting period, performance by individual name was more diverse than usual, with some issues showing relative resilience while others sold off significantly. Moreover, duration and credit spread widening worked against the Fund in the downturn due to its leverage. The dramatic increase in AAA municipal bond yields during March 2020 negatively affected leveraged funds in the short term, which we viewed as a temporary situation and did not merit any wholesale changes to the Fund’s positioning. High yield municipal credit spreads also increased significantly beyond their long-term average in March 2020. The catalysts for the move were part technical and part fundamental. The general fear pervading the markets and investors’ rush to liquidate to cash contributed to technical selling pressure that spiraled into more selling. At the same time, the pandemic and associated economic fallout was expected to increase credit rating downgrades (and possibly defaults), which further weighed on valuations.
8
 

In this environment, NMZ’s most prominent underperformers included Metropolitan Pier and Exposition Authority at McCormick, which the market priced lower due to the temporary restrictions on tourism and convention activity in Chicago; Buckeye Tobacco Settlement bonds, which suffered short-term technical selling pressure; American Dream Meadowlands, the mega-mall shopping and entertainment complex in New Jersey that had begun its phased opening but was delayed when the virus hit; U.S. Steel, which was hurt by falling commodity prices and volatile equity markets; and Virgin Trains USA Passenger Rail Project, a high-speed privately operated South Florida rail line, whose next phase of expansion is under construction and, despite the COVID-19 crisis, remains on time and under budget.
Conversely, NMZ’s notable outperformers included Energy Harbor, which performed well as its predecessor company FirstEnergy Solutions successfully emerged from bankruptcy (as described in the strategy section of this commentary). Our longstanding positions in charter schools and land-secured bonds also held up relatively well in the challenging environment. The charter school movement remains strong. Moreover, their funding for this year wasn’t disrupted by the coronavirus because state budgets are set annually and is unlikely to be cut going forward because it represents a small allocation and tends to enjoy a higher priority in state budgets. Renaissance Charter School and Thomas Jefferson Classical Academy, which offered relatively high coupons and were priced to shorter call dates, were among the top performers for NMZ. The Fund no longer holds Thomas Jefferson Classical Academy. The pandemic is also unlikely to disrupt some of the longer-term (10- to 15-year) trends in the real estate market, in our view, especially the need for new single-family homes in certain areas. NMZ’s best performing land-secured bonds included Lancaster County, South Carolina, Edgewater Improvement District, Pine Island Community Development District (Florida) and Ave Maria Community District (Florida). NMZ also benefited from low exposure to senior living/life care facilities, the weakest performing sector.
NMCO’s performance is also primarily compared to the S&P Municipal Yield Index. The Fund had been outperforming the benchmark during the reporting period up until March 2020 but the March-April market downturn reversed those gains. The Fund’s weakest performing holdings were the more widely traded, highly liquid, high yield names with greater sensitivity to market movements, such as Puerto Rico COFINAs, Buckeye Tobacco Settlement and Illinois sales tax revenue bonds. These bonds’ prices became severely dislocated from fundamentals during the March 2020 liquidity crunch. Despite having high debt service coverage ratios (and therefore lower risk of potential default), these names are among the most liquid high yield bonds, which makes them among the first to be sold in times of market stress. NMCO’s Puerto Rico position, which included both COFINA and Puerto Rico Electric Power Authority (known as PREPA) bonds, was among the bottom performers in this reporting period.
Offsetting some of the negative performance was the strong performance of tobacco settlement bonds (mainly due to the legacy Buckeye Tobacco Settlement bonds) and IDR bonds (largely due to FirstEnergy Solutions (renamed Energy Harbor). NMCO had no exposure to the senior living/life care sector, which was also advantageous.

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. The Funds obtain leverage through the issuance of preferred shares and/or investments in inverse floating rate securities, which itself represents a leverage investment in an underlying bond.
The Funds primarily utilize leverage in order to generate incremental income. The Funds are able to do so by earning a greater amount of interest on additional higher yielding long-term bond investments than its associated leverage expense, which is typically based upon short-term rates. This has been particularly true in recent market environments where short-term rates have been low by historical standards. Common share income in leveraged funds will typically decrease in comparison to unleveraged funds when short-term rates increase and increase with short-term rates decrease.
In return for the opportunity of higher incremental income, the Funds’ common shareholders assume additional price variability, so their net asset value will be more volatile. Common shareholders will experience a greater increase in their net asset value if the municipal bonds acquired through the use of leverage increase in value, but correspondingly will have a greater decline in their net asset value if the bonds acquired through leverage decline in price.
Management believes that the potential benefit from leverage continues to outweigh the associated risk from increased price variability as previously described. Historically, over most longer periods of time, incremental income derived from leverage has more than offset the added price variability and led to higher total returns. However, during shorter time periods, this added price variability can equal or exceed any incremental income so that, when compared to an unleveraged fund, leverage may reduce total returns during the period.
During the recent semi-annual period, leverage had a negative impact on the total return performance of each Fund. Throughout much of the reporting period the total return performance for each Fund was aided by not only the incremental income from leverage, but also the added price appreciation of its underlying bond portfolio. However, beginning of the second week of March, the overall municipal market experienced a severe sell-off due to the COVID-19 economic shutdown. The sell-off was even more pronounced for the lower rated segments of the municipal market and contributed to greater relative underperformance during that time period for those funds, such as NMZ and NMCO, which have a greater proportion of their portfolio holdings in such securities. For all Funds, leverage amplified these market declines and more than offset prior months’ net asset value appreciation and incremental income.
During this period of sharp portfolio decline, the Funds’ effective leverage ratios increased. NMCO reduced the total amount of leverage deployed by approximately 13% during this time period while the other Funds maintained their total amount of leverage. As markets began to somewhat recover after the March sell-off and through the end of the reporting period, leverage worked in each Fund’s favor. That recovery also caused the Funds’ respective leverage ratio to also decline.
Despite the significant negative impact of leverage at the end of the period, management continues to believe that over the longer term leverage for each Fund will continue to enhance the Funds’ net income and total return prospects. For those Funds which have longer investment track records (NVG, NZF and NMZ) we point to the strong 10-year returns of the Funds compared to their unlevered benchmark index, shown on ensuing pages, which results encompass the negative impact of leverage during March and April of 2020.

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.

*     Distribution paid in December 2019.
**    Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is based on an income tax rate of 40.8%. Your actual federal income tax rate may differ from the assumed rate. The Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on payments made during the previous calendar year) that was not exempt from federal income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.
Each Fund seeks to pay regular monthly dividends out of its net investment income at a rate that reflects its past and projected net income performance. To permit each Fund to maintain a more stable monthly dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net income actually earned by the Fund during the period. Distributions to common shareholders are determined on a tax basis, which may differ from amounts recorded in the accounting records. In instances where the monthly dividend exceeds the earned net investment income, the Fund would report a negative undistributed net ordinary income. Refer to Note 6 — Income Tax Information for additional information regarding the amounts of undistributed net ordinary income and undistributed net long-term capital gains and the character of the actual distributions paid by the Fund during the period.
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.
CHANGE IN METHOD OF PUBLISHING NUVEEN CLOSED-END FUND DISTRIBUTION AMOUNTS
During November 2019, the Nuveen Closed-End Funds discontinued the practice of announcing Fund distribution amounts and timing via press release. Instead, information about the Nuveen Closed-End Funds’ monthly and quarterly periodic distributions to shareholders will be posted and can be found on Nuveen’s enhanced closed-end fund resource page, which is at www.nuveen.com/closed-end-fund-distributions, along with other Nuveen closed-end fund product updates. Shareholders can expect regular distribution information to be posted on www.nuveen.com on the first business day of each month. To ensure that our shareholders have timely access to the latest information, a subscribe function can be activated at this link here, or at this web page (www.nuveen.com/en-us/people/about-nuveen/for-the-media).
COMMON SHARE EQUITY SHELF PROGRAM
During the current reporting period, NMZ was authorized by the Securities and Exchange Commission to issue additional common shares through an equity shelf program (Shelf Offering). Under this program, NMZ, subject to market conditions, may raise additional capital from time to time in varying amounts and offering methods at a net price at or above the Fund’s NAV per common share. The total amount of common shares authorized under this Shelf Offering, are as shown in the accompanying table.

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)

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.

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 (Unaudited)
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 April 30, 2020, and the period covered by these Notes to Financial Statements is the six months ended April 30, 2020 (the “current fiscal period”).
Investment Adviser and Sub-Adviser
The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub-advisory agreements with Nuveen Asset Management, LLC (the “Sub-Adviser”), a subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds.
Fund Merger
Effective prior to the opening of business on November 18, 2019, Nuveen Connecticut Quality Municipal Income Fund (NTC) (the “Target Fund”) was merged into NVG (the “Acquiring Fund”) (the “Merger”).
For accounting and performance reporting purposes, the Acquiring Fund is the survivor.
Upon the closing of the Merger, the Target Fund transferred its assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund and the assumption by the Acquiring Fund of the liabilities of the Target Fund. The Target Fund was then liquidated, dissolved and terminated in accordance with its Declaration of Trust. Shareholders of the Target Fund became shareholders of the Acquiring Fund. Holders of common shares of the Target Fund received newly issued common shares of the Acquiring Fund, the aggregate net asset value (“NAV”) of which is equal to the aggregate NAV of the common shares of the Target Fund held immediately prior to the Merger (including for this purpose fractional Acquiring Fund shares to which shareholders were entitled). Holders of preferred shares of the Target Fund receive on a one-for-one basis newly issued preferred shares of the Acquiring Fund, in exchange for preferred shares of the Target Fund held immediately prior to the Merger. Details of the Merger are further described in Note 9 – Fund Merger.
Other Matters
The outbreak of the novel coronavirus (“COVID-19”) and subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the calendar quarter ended March 31, 2020. The worldwide spread of COVID-19 has created significant uncertainty in the global economy. The duration and extent of COVID-19 over the long-term cannot be reasonably estimated at this time. There have been no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have on the Funds’ financial performance. The ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Funds’ normal course of business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Management continues to monitor and evaluate this situation.
154
 

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 NAV for financial reporting purposes may differ from the NAV for processing security and common share transactions. The NAV for financial reporting purposes includes security and common share transactions through the date of the report. Total return is computed based on the NAV used for processing security and common share transactions. The following is a summary of the significant accounting policies consistently followed by the Funds.
Compensation
The Funds pay no compensation directly to those of its trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Funds’ Board of Trustees (the “Board”) has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.
Distributions to Common Shareholders
Distributions to common shareholders are recorded on the ex-dividend date. The amount, character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.
Indemnifications
Under the Funds’ organizational documents, their officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.
Investments and Investment Income
Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Investment income is comprised of interest income, which is recorded on an accrual basis and includes accretion of discounts and amortization of premiums for financial reporting purposes. Investment income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash. Investment income also reflects dividend income, which is recorded on the ex-dividend date.
Netting Agreements
In the ordinary course of business, the Funds may enter into transactions subject to enforceable International Swaps and Derivative Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, each Fund manages its cash collateral and securities collateral on a counterparty basis.
The Funds’ investments subject to netting agreements as of the end of the reporting period, if any, are further described in Note 4 – Portfolio Securities and Investments in Derivatives.
New Accounting Pronouncements and Rule Issuances
FASB Accounting Standards Update (“ASU”) 2017-08 (“ASU 2017-08”) Premium Amortization on Purchased Callable Debt Securities
The FASB has issued ASU 2017-08, which shortens the premium amortization period for purchased non-contingently callable debt securities. ASU 2017-08 specifies that the premium amortization period ends at the earliest call date, for purchased non-contingently callable debt securities. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. During the current fiscal period, ASU 2017-08 became effective for the Funds and it did not have a material impact on the Funds’ financial statements.
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.
155
 

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

As of the measurement date, Municipal Bonds and Corporate Bonds categorized as Level 3 are fair valued utilizing a recovery estimate based on non-public information, except Colorado Energy LLC held in NMZ which is priced at placeholder value of $0.001 given the remote chance for recovery.
The table below presents the transfers in and out of the three valuation levels for the Funds as of the end of the reporting period when compared to the valuation levels at the end of the previous fiscal year. Changes in valuation inputs or methodologies may result in transfers into or out of an assigned level within the fair value hierarchy. Transfers in or out of levels are generally due to the availability of publicly available information and to the significance or extent the Adviser determines that the valuation inputs or methodologies may impact the valuation of those securities.

4. Portfolio Securities 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.
158
 

The Inverse Floater held by a Fund gives the Fund the right to (a) cause the holders of the Floaters to tender their certificates at par (or slightly more than par in certain circumstances), and (b) have the trustee of the TOB Trust (the “Trustee”) transfer the Underlying Bond held by the TOB Trust to the Fund, thereby collapsing the TOB Trust.
The Fund may acquire an Inverse Floater in a transaction where it (a) transfers an Underlying Bond that it owns to a TOB Trust created by a third party or (b) transfers an Underlying Bond that it owns, or that it has purchased in a secondary market transaction for the purpose of creating an Inverse Floater, to a TOB Trust created at its direction, and in return receives the Inverse Floater of the TOB Trust (referred to as a “self-deposited Inverse Floater”). A Fund may also purchase an Inverse Floater in a secondary market transaction from a third party creator of the TOB Trust without first owning the Underlying Bond (referred to as an “externally-deposited Inverse Floater”).
An investment in a self-deposited Inverse Floater is accounted for as a “financing” transaction (i.e., a secured borrowing). For a self-deposited Inverse Floater, the Underlying Bond deposited into the TOB Trust is identified in the Fund’s Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund recognizing as liabilities, labeled “Floating rate obligations” on the Statement of Assets and Liabilities, (a) the liquidation value of Floaters issued by the TOB Trust, and (b) the amount of any borrowings by the TOB Trust from a Liquidity Provider to enable the TOB Trust to purchase outstanding Floaters in lieu of a remarketing. In addition, the Fund recognizes in “Investment Income” the entire earnings of the Underlying Bond, and recognizes (a) the interest paid to the holders of the Floaters or on the TOB Trust’s borrowings, and (b) other expenses related to remarketing, administration, trustee, liquidity and other services to a TOB Trust, as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. Earnings due from the Underlying Bond and interest due to the holders of the Floaters as of the end of the reporting period are recognized as components of “Receivable for interest” and “Payable for interest” on the Statement of Assets and Liabilities, respectively.
In contrast, an investment in an externally-deposited Inverse Floater is accounted for as a purchase of the Inverse Floater and is identified in the Fund’s Portfolio of Investments as “(IF) – Inverse floating rate investment.” For an externally-deposited Inverse Floater, a Fund’s Statement of Assets and Liabilities recognizes the Inverse Floater and not the Underlying Bond as an asset, and the Fund does not recognize the Floaters, or any related borrowings from a Liquidity Provider, as a liability. Additionally, the Fund reflects in “Investment Income” only the net amount of earnings on the Inverse Floater (net of the interest paid to the holders of the Floaters or the Liquidity Provider as lender, and the expenses of the Trust), and does not show the amount of that interest paid or the expenses of the TOB Trust as described above as interest expense on the Statement of Operations.
Fees paid upon the creation of a TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters are recognized as part of the cost basis of the Inverse Floater and are capitalized over the term of the TOB Trust.
As of the end of the reporting period, the aggregate value of Floaters issued by each Fund’s TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters was as follows:

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.
159
 

Notes to Financial Statements (Unaudited) (continued)
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, NMZ had outstanding borrowings under such liquidity facilities in the amount of $3,621,228, which are recognized as a component of “Floating rate obligations” on the Statement of Assets and Liabilities. There were no loans outstanding under such facilities for other Funds as of the end of the reporting period.
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:

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.

The Funds may purchase securities on a when-issued or delayed-delivery basis. Securities purchased on a when-issued or delayed-delivery basis may have extended settlement periods; interest income is not accrued until settlement date. Any securities so purchased are subject to market fluctuation during this period. The Funds have earmarked securities in their portfolios with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. If a Fund has outstanding when-issued/delayed-delivery purchases commitments as of the end of the reporting period, such amounts are recognized on the Statement of Assets and Liabilities.
Investments in Derivatives
In addition to the inverse floating rate securities in which each Fund may invest, which are considered portfolio securities for financial reporting purposes, each Fund is authorized to invest in certain other derivative instruments such as futures, options and swap contracts. Each Fund limits its investments in futures, options on futures and swap contracts to the extent necessary for the Adviser to claim the exclusion from registration by the Commodity Futures Trading Commission as a commodity pool operator with respect to the Fund. The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds’ investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.
Although the Funds are authorized to invest in derivative instruments, and may do so in the future, they did not make any such investments during the current fiscal period.
Market and Counterparty Credit Risk
In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk,
160

consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.
Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.
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 a prior fiscal period.
Under this Shelf Offering, the Fund, subject to market conditions, may raise additional equity capital by issuing additional common shares from time to time in varying amounts and by different offering methods at a net price at or above the Fund’s NAV per common share. In the event the Fund’s Shelf Offering registration statement is no longer current, the Fund may not issue additional common shares until a post-effective amendment to the registration statement has been filed with the SEC.
Additional authorized common shares, common shares sold and offering proceeds, net of offering costs under the Fund’s Shelf Offering during the Fund’s current and prior fiscal period were as follows:

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.

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

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
162
 

“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 each Fund’s offering of AMTP Shares were recorded as deferred charges, which are amortized over the life of the shares and are recognized as components of “Adjustable Rate MuniFund Term Preferred (“AMTP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities and “Interest expense and amortization of offering costs” on the Statement of Operations.
MuniFund Preferred Shares
The following Funds have issued and have outstanding MuniFund Preferred (“MFP”) Shares, with a $100,000 ($1,000 for NVG’s Series B) liquidation preference per share. These MFP Shares were issued via private placement and are not publically available.
The Funds are obligated to redeem their MFP Shares by the date as specified in its offering documents (“Term Redemption Date”), unless earlier redeemed by the Funds. MFP Shares are initially issued in a pre-specified mode, however, MFP Shares can be subsequently designated as an alternative mode at a later date at the discretion of the Funds. The modes within MFP Shares detail the dividend mechanics and are described as follows. At a subsequent date, the Fund may establish additional mode structures with the MFP Share.
Variable Rate Remarketed Mode (“VRRM”) – Dividends for MFP Shares within this mode will be established by a remarketing agent; therefore, 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.

Notes to Financial Statements (Unaudited) (continued)
Subject to certain conditions, MFP Shares may be redeemed, in whole or in part, at any time at the option of the Fund. The Fund may also be required to redeem certain MFP shares if the Fund fails to maintain certain asset coverage requirements and such failures are not cured by the applicable cure date. The redemption price per share in all circumstances is equal to the liquidation preference per share plus any accumulated but unpaid dividends.
NMCO incurred offering costs of $1,136,140 in connection with its offering of MFP Shares, which were recorded as a deferred charge and are being amortized over the life of the shares. These offering costs are recognized as a component of “MuniFund Preferred (“MFP”) Shares, net of deferred offering costs” on the Statement of Assets and Liabilities and “Interest expense and amortization of offering costs” on the Statement of Operations.
As of the end of the reporting period, NVG, NZF and NMCO had $403,883,992, $639,992,116 and $448,891,324 of MFP Shares at liquidation preference, net of deferred offering costs, respectively.

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:

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.

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 April 30, 2020.

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:

* 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 April 30, 2020, the complex-level fee for each Fund was 0.1593%.
Other Transactions with Affiliates
Each Fund is permitted to purchase or sell securities from or to certain other funds or accounts managed by the Sub-Adviser (“Affiliated Entity”) under specified conditions outlined in procedures adopted by the Board (“cross-trade”). These procedures have been designed to ensure that any cross-trade of securities by the Fund from or to an Affiliated Entity by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 under the 1940 Act. These transactions are effected at the current market price (as provided by an independent pricing service) without incurring broker commissions.
During the current fiscal period, the Funds engaged in cross-trades pursuant to these procedures as follows:

8. Borrowing Arrangements
Committed Line of Credit
The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, $2.65 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.

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

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. Fund Merger
The Merger as previously described in Note 1 — General Information was structured to qualify as a tax-free merger under the Internal Revenue Code for federal income tax purposes, and the Target Fund’s shareholders recognized no gain or loss for federal income tax purposes as a result. Prior to the closing of the Merger, the Target Fund distributed all of its net investment income and capital gains, if any. Such a distribution may be taxable to the Target Fund’s shareholders for federal income tax purposes.
169
 

Notes to Financial Statements (Unaudited) (continued)
Investments
The cost, fair value and net unrealized appreciation (depreciation) of the investments (including investments in derivatives) of the Target Fund as of the date of the Merger, were as follows:
 
NTC 
Cost of investments 
$278,923,665 
Fair value of investments 
294,696,476 
Net unrealized appreciation (depreciation) of investments 
15,772,811 
For financial reporting purposes, assets received and shares issued by the Acquiring Fund were recorded at fair value; however, the cost basis of the investments received from the Target Fund were carried forward to align ongoing reporting of the Acquiring Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.
Common Shares
The common shares outstanding, net assets applicable to common shares and NAV per common share outstanding immediately before and after the Merger were as follows:
Target Fund – Prior to Merger 
NTC 
Common shares outstanding 
14,328,976 
Net assets applicable to common shares 
$184,807,196 
NAV per common share outstanding 
$ 12.90 
Acquiring Fund – Prior to Merger 
NVG 
Common shares outstanding 
202,552,895 
Net assets applicable to common shares 
$3,460,366,031 
NAV per common share outstanding 
$ 17.08 
Acquiring Fund – Post Merger 
NVG 
Common shares outstanding 
213,370,544 
Net assets applicable to common shares 
$3,645,173,227 
NAV per common share outstanding 
$ 17.08 
Pro Forma Results of Operations
The beginning of the Target Fund’s current fiscal period was June 1, 2019. Assuming the Merger had been completed on November 1, 2019, the beginning of the Acquiring Fund’s current fiscal period, the pro forma results of operations for the current fiscal period, are as follows:
Acquiring Fund – Pro Forma Results from Operations 
NVG 
Net investment income (loss) 
$ 81,945,091 
Net realized and unrealized gains (losses) 
(370,274,566) 
Change in net assets resulting from operations 
(288,329,475) 
Because the combined investment portfolios for the Merger have been managed as a single integrated portfolio since the Merger was completed, it is not practicable to separate the amounts of revenue and earnings of the Target Fund that have been included in the Statement of Operations for the Acquiring Fund since the Merger was consummated.
Cost and Expenses
In connection with the Merger, the Acquiring Fund incurred certain associated costs and expenses. Such amounts were included as components of “Accrued other expenses” on the Statement of Assets and Liabilities and “Merger expenses” on the Statement of Operations.
10. Subsequent Events
Variable Rate Demand Preferred Shares
On June 14, 2020 and June 15, 2020, NVG’s Series 1 VRDP Shares and Series 4 VRDP Shares remarketing fees changed from 0.08% to 0.10%, respectively.
170
 

Committed Line of Credit
During June 2020, the Participating Funds renewed the standby credit facility through June 2021. In conjunction with this renewal the commitment amount decreased from $2.65 billion to $2.405 billion and the interest rate increased from LIBOR plus 1.00% to LIBOR plus 1.25%. The Participating Funds also incurred a 0.10% upfront fee. All other terms remain unchanged.

Glossary of Terms Used in this Report
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.

Industrial Development Revenue Bond (IDR): A unique type of revenue bond issued by a state or local government agency on behalf of a private sector company and intended to build or acquire factories or other heavy equipment and tools.

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

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

NVG and NZF Custom Blended Fund Performance Benchmark: The Fund Performance Benchmark is an unleveraged index consisting of the returns of the S&P Municipal Bond Index prior to 4/11/16 and thereafter the returns of an 60%/40% blend of the S&P Municipal Bond Investment Grade Index and the S&P Municipal Bond High Yield Index, respectively. The S&P Municipal Bond Index is an unmanaged, market value-weighted index designed to measure the performance of tax-exempt municipal bonds. The S&P Municipal Bond Investment Grade Index is an unmanaged, market value-weighted index designed to measure the 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.
173
 

Glossary of Terms Used in this Report (continued)
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.
