Chairman's Letter to Shareholders

Dear Shareholders,

After a sluggish first half of 2016, the U.S. economy gained some momentum in the third quarter. In fact, it was the economy's strongest quarterly acceleration in two years, propelled by healthy consumer spending, a temporary surge in exports and a turnaround in inventories. As the year winds down, 2016 looks on track to deliver the same steady-but-slow growth that has characterized the seven-year recovery.

A year ago, the U.S. Federal Reserve (Fed) took the first step toward policy "normalization" by raising its benchmark interest rate at its December 2015 meeting. Speculation about the Fed's intentions since then has been a strong influence on the markets throughout 2016. After remaining on hold for a year, the Fed judged that the economy's modest growth, the return to "full" employment and an uptick in inflation were sufficient to raise the target rate at the December 2016 meeting.

Global conditions continue to look subdued by comparison. Investors continue to adjust to the idea of a slower Chinese economy, which has helped commodity prices stabilize and lift global inflation expectations. The U.K.'s June 23rd "Brexit" vote to leave the European Union introduced a new set of economic and political uncertainties to the already fragile conditions across Europe. Moreover, there are growing concerns that global central banks' unprecedented efforts to revive growth may be showing signs of fatigue. Interest rates are currently negative in Europe and Japan and near or at zero in the U.S., U.K. and elsewhere; nonetheless, growth has remained subdued.

Since the election, U.S. stocks have rallied strongly on expectations that the Republican controlled Congress and Trump administration will pursue more business friendly policies. But the details have yet to be seen. Given muted global growth, the risk of policy errors by central banks around the world, the unfolding Brexit process and an uncertain political outlook (not just in the U.S. but also in Europe), we anticipate that turbulence remains on the horizon for the time being. In this environment, Nuveen remains committed to both managing downside risks and seeking upside potential. If you're concerned about how resilient your investment portfolio might be, we encourage you to talk to your financial advisor. 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,

William J. Schneider Chairman of the Board December 22, 2016

Portfolio Managers' Comments

Nuveen AMT-Free Municipal Credit Income Fund (NVG) Nuveen Municipal Credit Income Fund (NZF) Nuveen Municipal High Income Opportunity Fund (NMZ)

These Funds feature portfolio management by Nuveen Asset Management, LLC, an affiliate of Nuveen Investments, Inc. Portfolio managers Paul L. Brennan, CFA, Scott R. Romans, PhD, and John V. Miller, CFA, discuss U.S. economic and municipal market conditions, key investment strategies and the twelve-month performance of these three national Funds.

Effective April 11, 2016, Scott R. Romans, PhD, has assumed portfolio management responsibilities for NZF.

Effective April 11, 2016, a secondary benchmark (60% S&P Municipal Bond Investment Grade Index and 40% S&P Municipal Bond High Yield Index) was added for NVG and NZF. The secondary benchmark was added to better reflect the Funds' mandates in conjunction with the Funds' reorganizations.

Effective May 26, 2016, the investment policy changed for NMZ. The investment policy change allows the Fund to increase the maximum percent allowed to be invested in municipal securities rated below B3/B- from 5% to 10%.

Effective December 28, 2016 (subsequent to the close of this reporting period), Nuveen AMT-Free Credit Income Fund (NVG) changed its name from Nuveen Enhanced AMT-Free Credit Opportunities Fund (NVG) and Nuveen Municipal Credit Income Fund (NZF) changed its name from Nuveen Enhanced Municipal Credit Opportunities Fund (NZF).

FUND REORGANIZATIONS

During August 2015, the Board of Directors/Trustees of the Nuveen Closed-End Funds approved a series of reorganizations for certain Funds (the Target Funds) to create two, larger-national Funds (the Acquiring Funds), which are included in this report.

The reorganizations are as follows:

Target Funds Symbol Acquiring Funds Symbol
Nuveen Municipal Opportunity Fund, Inc. NIO Nuveen Dividend Advantage Municipal Income NVG
Nuveen Quality Municipal Fund, Inc. NQI Fund, renamed Nuveen Enhanced AMT-Free
Nuveen Quality Income Municipal Fund, Inc. NQU Municipal Credit Opportunities Fund
Nuveen Premium Income Municipal Fund 4, Inc. NPT Nuveen Dividend Advantage Municipal Fund 3, NZF
Nuveen Dividend Advantage Municipal Fund 2 NXZ renamed Nuveen Enhanced Municipal Credit
Nuveen Municipal Advantage Fund, Inc. NMA Opportunities Fund

The forward-looking statements and other views expressed herein are those of the portfolio managers as of the date of this report. Actual future results or occurrences may differ significantly from those anticipated in any forward-looking statements, and the views expressed herein are subject to change at any time, due to numerous market and other factors. The Funds disclaim any obligation to update publicly or revise any forward-looking statements or views expressed herein.

The ratings disclosed are the lowest rating given by one of the following national rating agencies: Standard & Poor's (S&P), Moody's Investors Service, Inc. (Moody's) or Fitch, Inc. (Fitch). Credit ratings are subject to change. AAA, AA, A and BBB are investment grade ratings, while BB, B, CCC, CC, C and D are below investment grade ratings. Certain bonds backed by U.S. Government or agency securities are regarded as having an implied rating equal to the rating of such securities. Holdings designated N/R are not rated by these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.

Bond insurance guarantees only the payment of principal and interest on the bond when due, and not the value of the bonds themselves, which will fluctuate with the bond market and the financial success of the issuer and the insurer. Insurance relates specifically to the bonds in the portfolio and not to the share prices of a Fund. No representation is made as to the insurers' ability to meet their commitments.

What factors affected the U.S. economy and the national municipal market during the twelve-month reporting period ended October 31, 2016?

The restrained pace of growth that has defined the U.S. economic recovery since 2009 continued in the twelve-month reporting period. Growth over the previous four calendar quarters averaged below 2% (annualized), as measured by real gross domestic product (GDP), which is the value of goods and services produced by the nation's economy less the value of the goods and services used up in production, adjusted for price changes. For most of the reporting period, consumer spending remained healthy but was offset by the drag from the inventory cycle, lackluster business spending and weak net exports. As a result, GDP growth stayed below 1.5% from the fourth quarter of 2015 through the second quarter of 2016. However, decent consumer spending, an inventory turnaround and a short-term jump in exports contributed to a more robust gain of 3.2% in the third quarter, as reported by the "second" estimate of the Bureau of Economic Analysis.

Consumers, whose purchases comprise the largest component of the U.S. economy, benefited from employment growth and firming wages over the twelve-month reporting period. As reported by the Bureau of Labor Statistics, the unemployment rate was little changed at 4.9% in October 2016 from 5.0% in October 2015, and job gains averaged slightly above 200,000 per month for the past twelve months. Although consumer spending gains were rather muted in the latter half of 2015, spending surged in the second quarter of 2016. Although inflation began to accelerate slightly in the reporting period, the overall level remained low, which also contributed to consumers' willingness to buy. The Consumer Price Index (CPI) rose 1.6% over the twelve-month reporting period ended October 2016 on a seasonally adjusted basis, as reported by the U.S. Bureau of Labor Statistics. The core CPI (which excludes food and energy) increased 2.1% during the same period, slightly above the Fed's unofficial longer term inflation objective of 2.0%.

The housing market was another bright spot in the economy. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, recorded a 5.5% annual gain in September 2016 (most recent data available at the time this report was prepared) (effective July 26, 2016, the S&P/Case-Shiller U.S. National Home Price Index was renamed the S&P CoreLogic Case-Shiller U.S. National Home Price Index). The 10-City and 20-City Composites reported year-over-year increases of 4.3% and 5.1%, respectively.

However, business investment remained soft over the reporting period. Corporate earnings growth continued to be constrained by diminished demand expectations amid sluggish U.S. and global growth, the impact of falling commodity prices and a strong U.S. dollar. Additionally, a murky outlook kept capital spending muted. Concerns about financial market turbulence in early 2016, the U.K.'s "Brexit" vote to leave the European Union (EU) and the U.S. presidential election weighed on business sentiment throughout the reporting period.

The consistent growth of the economy prompted the U.S. Federal Reserve (Fed) to raise the Fed funds rate from the zero bound range to a range of 0.25% to 0.50% in December 2015. The widely anticipated move had little impact on the financial markets. Over the remainder of the reporting period, speculation on the timing of future rate hikes drove short-term swings in the markets, including falling bond yields, rallies in the U.S. dollar and bouts of volatility in stock prices. For most of 2016, the Fed kept this rate unchanged due to concerns ranging from low inflation in the U.S. to weakening growth prospects globally and the U.K.'s Brexit vote. However, the third quarter's strong GDP report and an uptick in inflation boosted expectations that the Fed would likely increase the target rate at the December 2016 meeting. As anticipated, subsequent to the close of the reporting period, the Fed raised the rate to a range of 0.50% to 0.75%.

6 NUVEEN

Other market-moving events during the reporting period included a spike in volatility in January and February 2016 triggered by deteriorating sentiment about China's economy, another sharp downturn in oil prices and concerns about central bank policy both in the U.S. and around the world. The Brexit referendum on June 23 also caught investors off guard. In response, U.K. sterling fell to 30-year lows and global equities tumbled while perceived safe-haven assets such as gold, the U.S. dollar and government bonds saw large inflows. However, the markets stabilized fairly quickly post-Brexit vote, buoyed by reassurances from global central banks and a perception that the temporary price rout presented an attractive buying opportunity. Following a relatively calm July and August 2016, volatility resumed in the final months of the reporting period. Investors worried whether central banks were reaching the limits of their effectiveness as global growth continues to stagnate. The health of the European banking sector came into question, renewing concerns about the potential to trigger a wider crisis. Political uncertainty increased leading up to the November U.S. presidential election, and after the close of the reporting period, the unexpected win of Donald Trump contributed to an initial sell-off across global markets. However, after digesting the "shock", U. S. equities rallied strongly and global developed market stocks pared their losses, while emerging markets, fixed income and gold remained lower.

The broad municipal bond market performed well during the twelve-month reporting period, supported by falling interest rates, a favorable supply-demand balance and generally improving credit fundamentals. Although interest rates began to drift higher in the final month of the reporting period in anticipation of a possible Fed rate hike in December, they still ended at lower than where they started the reporting period. The largest declines were in longer-dated bond yields, while yields on the short end (zero to four years) of the yield curve increased, driven by anticipation of new money market fund regulations that triggered volatility in short-term rates. This caused the municipal yield curve to flatten over the reporting period.

The demand for municipal bonds continued to outpace supply. During the reporting period, municipal bond gross issuance nationwide totaled $435.6 billion, a 2.9% gain from the issuance for the twelve-month period ended October 31, 2015. Gross issuance remains robust as issuers continue to actively and aggressively refund their outstanding debt given the very low interest rate environment. In these transactions the issuers are issuing new bonds and taking the bond proceeds and redeeming (calling) old bonds. These refunding transactions have ranged from 40%-60% of total issuance over the past few years. Thus, the net issuance (all bonds issued less bonds redeemed) is actually much lower than the gross issuance. In fact, the total municipal bonds outstanding has actually declined in each of the past four calendar years. So, the gross is surging, but the net is not and this has been an overall positive technical factor on municipal bond investment performance.

While supply has tightened, investor demand for municipal bonds has risen. Municipal bond mutual funds reported net inflows in 2015, and the inflows for the first four months of 2016 had already exceeded 2015's total volume for the year. The bouts of heightened volatility across other risky assets, uncertainty about the Fed's rate increases and the low to negative yields of European and Asian bonds have bolstered the appeal of municipal bonds' risk-adjusted returns and tax-equivalent yields. The municipal bond market is less directly influenced by the Fed's rate adjustments and its demand base is largely comprised of U.S. investors, factors which have helped municipal bonds deliver relatively attractive returns with less volatility than other market segments.

The fundamental backdrop also remained favorable for municipal bonds. Despite the U.S. economy's rather sluggish recovery, improving state and local balance sheets have contributed to generally good credit fundamentals. Higher tax revenue growth, better expense management and a more cautious approach to new debt issuance have led to credit upgrades and stable credit outlooks for many state and local issuers. While some pockets of weakness continued to grab headlines, including Illinois, New Jersey and Puerto Rico, their problems were largely contained, with minimal spillover into the broader municipal market.

What key strategies were used to manage these Funds during the twelve-month reporting period ended October 31, 2016?

Municipal market conditions remained favorable over the reporting period, supported by positive technical factors, stable credit fundamentals for municipal issuers and a backdrop of moderate economic growth and low inflation. During this time, we continued to take a bottom-up approach to discovering sectors that appeared undervalued as well as individual credits that we believed had the potential to perform well over the long term.

Portfolio Managers' Comments (continued)

Our trading activity continued to focus on pursuing the Funds' investment objectives. We continued to seek bonds in areas of the market that we expected to perform well as the economy continued to improve. The Funds' positioning emphasized intermediate and longer maturities, lower rated credits and sectors offering higher yields. To fund these purchases, we generally reinvested the proceeds from called and maturing bonds. In some cases, we sold bonds that we believed had deteriorating fundamentals or could be traded for a better relative value.

During this reporting period, NVG and NZF enacted changes to their investment strategies that allow the Funds to invest in a higher allocation to municipal securities rated BBB and below. The new mandate is intended to increase the Funds' potential net earnings in exchange for increased credit risk relative to historical levels. To align with this goal, NVG and NZF bought a range of lower rated credits, including tobacco settlement bonds, both Chicago- and Illinois-issued bonds, health care credits, charter school bonds, tax-backed land-secured issues and utility bonds. At the same time, we sold higher rated credits, especially AA rated bonds that were bought at lower embedded yields. NVG also eliminated any bonds subject to the alternative minimum tax (AMT) to complete its transition to an AMT-free Fund. Additionally, for both NVG and NZF, the proceeds from called bonds provided a considerable amount of the funding to invest in new opportunities, and the two Funds also invested the proceeds from incremental preferred share offerings that were conducted as part of the overall management of the Funds' leverage.

In NMZ, we continued to focus on research and the selection of individual credits with the potential for improvement as the key contributors to performance. NMZ emphasized bonds with above-market coupons and stable-to-improving credit fundamentals. Overall, the Fund's portfolio positioning remained relatively stable throughout the reporting period, as we invested across the yield curve and credit spectrum in the key sectors we favor. NMZ also holds bonds that make sinking fund payments, which are monies an issuer sets aside to periodically repay a portion of the bond issue during a bond's lifetime. During this reporting period, NMZ received ample cash from these sinking fund payments, dividend reinvestments and share offerings in the secondary market, as well as from maturing and called bonds, to fund its buying activity.

In terms of NMZ's purchases in this reporting period, we continued to favor areas of the market that have been key long-term overweight positions in the Fund's portfolio, including the industrial development revenue (IDR), land-backed and health care sectors. Our purchases were mainly in the secondary markets, where attractive values could be found among names that we believed suffered from overly negative sentiment, particularly in the first quarter of 2016 when concerns about economic weakness weighed heavily on the markets. We bought bonds issued for Indiana Finance Authority U.S. Steel and Maryland CNX Marine Terminal at deep discounts due to their exposure to commodity prices and the negative sentiment surrounding commodity supply surplus. However, the sentiment turned out to be overly bearish, which helped these bonds perform well in the second half of the reporting period. Another corporate-backed municipal bond we bought at a deep discount was Cook County Illinois Recovery Zone Facility Revenue Bond, Navistar International Corporation Project. Fears of economic recession earlier in 2016 hurt the earnings and credit ratings outlook for Navistar, an international heavy truck manufacturer. Later in the reporting period, the company benefited from positive news surrounding a joint venture with Volkswagen. We also bought Chicago Board of Education local general obligation (GO) bonds, which offered high yields and long maturities, and were available at attractive prices due to heightened concerns about the financial health of the Chicago public school system. Subsequently, the clarification of certain legal issues surrounding the school district's financial problems helped the bond rebound. We continue to own all of these bonds.

As of October 31, 2016, 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. NVG also invested in forward interest rates swaps as part of its duration management strategies, to help reduce price volatility risk to movements in U.S. interest rates relative to the Fund's benchmark. Although these swaps had a negative impact on performance, the Fund's overall duration positioning was a positive contributor to performance during this reporting period.

How did the Funds perform during the twelve-month reporting period ended October 31, 2016?

The tables in each Fund's Performance Overview and Holding Summaries section of this report provide the Funds' total returns for the one-year, five-year and ten-year periods ended October 31, 2016. Each Fund's total returns at net asset value (NAV) are compared with the performance of a corresponding market index and Lipper classification average.

8 NUVEEN

For the twelve months ended October 31, 2016, the total returns at NAV for all three of these Funds exceeded the return for the national S&P Municipal Bond Index. NVG and NZF outperformed the return for the new secondary benchmark referred to as the NVG and NZF Custom Blended Fund Performance Benchmark, which is composed of 60% S&P Municipal Bond Investment Grade Index and 40% S&P Municipal Bond High Yield Index and outperformed the average return for the Lipper General & Insured Leveraged Municipal Debt Funds Classification Average. NMZ underperformed the return on the S&P Municipal Bond High Yield Index and the return for the Lipper High-Yield Municipal Debt Funds Classification Average.

For NVG and NZF, duration and yield curve positioning was the main positive contributor to performance for the Funds during this reporting period. Consistent with our long term strategy, these Funds tended to have longer durations than the benchmark, with overweightings in the longer parts of the yield curve that performed well and underweightings in the underperforming shorter end of the curve.

Credit ratings allocations also boosted performance of NVG and NZF during this reporting period. The returns of lower quality bonds generally outpaced those of higher quality credits due to investor demand for higher yielding assets and a willingness to increase credit risk because of improving credit fundamentals. The Funds' overweight allocations to the lower quality categories and underweight allocations to AAA and AA rated credits were advantageous to performance.

For NMZ, which is primarily compared to the S&P Municipal Bond High Yield Index, many of the same factors drove its performance, including its longer duration and maturity profile. Credit conditions in the high yield market excluding Puerto Rico continued to be stable over the reporting period, with relatively low defaults in the marketplace and no material impact to NMZ's portfolio. Credit spreads narrowed slightly, which was beneficial to NMZ's performance.

Within the high yield segment of the municipal bond market, tobacco and Puerto Rico bonds continued to be the largest movers during this reporting period. The Fund had no exposure to Puerto Rico credits during this reporting period, which was beneficial to performance because the group underperformed due to the Commonwealth's weakening credit outlook. The tobacco sector, in contrast, bested all other sectors by a wide margin during this reporting period. Tobacco credits benefited from their liquidity during a period of strong investor demand and a surprise uptick in cigarette sales in 2015. The Fund's underweight tobacco exposure was a detractor from relative performance. Although the Fund's tobacco weighting did marginally increase over the reporting period mostly because of market appreciation and to a lesser extent trading activity, it remained well below that of the benchmark index because we consider the high yield benchmark's weight to be too high for NMZ given our current assessment of the sector.

Individual credit selections added value during this reporting period, due to spread narrowing and higher distribution yields across a diverse range of sectors and issues. Among NMZ's top performing bonds for this reporting period was a local GO issued for the Chicago Board of Education. The bond saw a turnaround from its low point in early 2016, as some of the legal and state funding concerns that previously depressed the bond have been alleviated, which led to improving credit conditions and a narrowing in credit spreads. NMZ also benefited from a position in New York Liberty for World Trade Center 3 bonds due to progress in the project's construction and strong leasing activity, as well as by the scarcity value of New York City tax-exempt bonds. The Fund's exposures to U.S. Steel, Maryland CNX Marine Terminal and the Cook County Illinois Recovery Zone Facility Revenue Bond, Navistar International Corporation Project were also advantageous over this reporting period. A rebound in investor sentiment and improved economic data contributed to spread narrowing for these bonds, which buoyed performance.

In addition, the use of regulatory leverage was an important positive factor affecting performance of the three Funds. Leverage is discussed in more detail later in the Fund Leverage section of this report.

An Update Involving Puerto Rico

As noted in the Funds' previous shareholder reports, we continue to monitor situations in the broader municipal market for any impact on the Funds' holdings and performance: the ongoing economic problems of Puerto Rico is one such case. Puerto Rico's continued economic weakening, escalating debt service obligations, and long-standing inability to deliver a balanced budget led to multiple downgrades on its debt over the past two years. Puerto Rico has warned investors since 2014 that the island's debt burden may be unsustainable and the Commonwealth has been exploring various strategies to deal with this burden, including Chapter 9

bankruptcy, which is currently not available by law. On June 30, 2016, President Obama signed the Puerto Rico Oversight, Management and Economic Stability Act (PROMESA) into law. The legislation creates a path for Puerto Rico to establish an independent oversight board responsible for managing the government's financial operations and restructure debt. Implementation is expected to take time, as the law focuses on developing a comprehensive five-year fiscal plan.

In terms of Puerto Rico holdings, shareholders should note that, as of the end of this reporting period, NVG and NZF had limited exposure, 0.4% and 0.2%, respectively, which was either insured or investment grade, to Puerto Rico debt, and NMZ did not hold any Puerto Rico bonds. NVG began the reporting period with no exposure to Puerto Rico bonds, but a small position was acquired in the fund reorganization during the reporting period. The Puerto Rico credits offered higher yields, added diversification and triple exemption (i.e., exemption from most federal, state and local taxes). Puerto Rico general obligation debt is currently rated Caa2/CC/CC (below investment grade) by Moody's, S&P and Fitch, respectively, with negative outlooks.

A Note About Investment Valuations

The municipal securities held by the Funds are valued by the Funds' pricing service using a range of market-based inputs and assumptions. A different municipal pricing service might incorporate different assumptions and inputs into its valuation methodology, potentially resulting in different values for the same securities. These differences could be significant, both as to such individual securities, and as to the value of a given Fund's portfolio in its entirety. Thus, the current net asset value of a Fund's shares may be impacted, higher or lower, if the Fund were to change pricing service, or if its pricing service were to materially change its valuation methodology. On October 4, 2016, the Funds' current municipal bond pricing service was acquired by the parent company of another pricing service. The two services have not yet combined their valuation organizations and process, but may do so in the future. Thus there is an increased risk that the organization acting as each Fund's pricing service may change, or that the Funds' pricing service may change its valuation methodology, either of which could have an impact on the net asset value of each Fund's shares.

Fund Leverage

IMPACT OF THE FUNDS' LEVERAGE STRATEGIES ON PERFORMANCE

One important factor impacting the returns of the Funds relative to their comparative benchmarks was the Funds' use of leverage through their issuance of preferred shares and/or investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. The Funds use leverage because our research has shown that, over time, leveraging provides opportunities for additional income, particularly in the recent market environment where short-term market rates are at or near historical lows, meaning that the short-term rates the Fund has been paying on its leveraging instruments have been much lower than the interest the Fund has been earning on its portfolio of long-term bonds that it has bought with the proceeds of that leverage. However, use of leverage also can expose the Fund to additional price volatility. When a Fund uses leverage, the Fund will experience a greater increase in its net asset value if the municipal bonds acquired through the use of leverage increase in value, but it will also experience a correspondingly larger decline in its net asset value if the bonds acquired through leverage decline in value, which will make the Fund's net asset value more volatile, and its total return performance more variable over time. In addition, income in levered funds will typically decrease in comparison to unlevered funds when short-term interest rates increase and increase when short-term interest rates decrease. Leverage made a positive contribution to the performance of these Funds over this reporting period.

As of October 31, 2016, the Funds' percentages of leverage are as shown in the accompanying table.

NVG NZF NMZ
Effective Leverage* 37.59% 37.06% 34.16%
Regulatory Leverage* 32.89% 34.32% 9.94%
  • Effective Leverage is a Fund's effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative and other investments in a Fund's portfolio that increase the Fund's investment exposure. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage. Regulatory leverage consists of preferred shares issued or borrowings of a Fund. Both of these are part of a Fund's capital structure. Regulatory leverage is subject to asset coverage limits set forth in the Investment Company Act of 1940.

* In connection with their reorganizations, NVG and NZF declared a dividend of $0.0504 and $0.0131, respectively, per common share with an ex-dividend date of April 6, 2016, payable on May 2, 2016, a dividend of $0.0141 and $0.0559, respectively, per common share with an ex-dividend date of April 19, 2016, payable on May 2, 2016.
** Distribution paid in December 2015.
*** Market Yield is based on the Fund's current annualized monthly dividend divided by the Fund's current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is based on a federal income tax rate of 28.0%. When comparing a Fund to investments that generate qualified dividend income, the Taxable-Equivalent Yield is lower.

Each Fund in this report 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. If a Fund has cumulatively earned more than it has paid in dividends, it will hold the excess in reserve as undistributed net investment income (UNII) as part of the Fund's net asset value. Conversely, if a Fund has cumulatively paid in dividends more than it has earned, the excess will constitute a negative UNII that will likewise be reflected in the Fund's net asset value. Each Fund will, over time, pay all its net investment income as dividends to shareholders.

As of October 31, 2016, all the Funds had positive UNII balances for tax purposes and positive UNII balances for financial reporting purposes.

Common Share Information (continued)

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 was sourced from or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders would have received a notice to that effect. For financial reporting purposes, the composition and per share amounts of each Fund's dividends for the reporting period are presented in this report's Statement of Changes in Net Assets and Financial Highlights, respectively. 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.

COMMON SHARE EQUITY SHELF PROGRAMS

During the current reporting period, NMZ was authorized by the Securities and Exchange Commission (SEC) 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. During the current fiscal period, the Fund was authorized to issue additional common shares under one or more Shelf Offerings. The total amount of common shares authorized under these Shelf Offerings are as shown in the accompanying table:

NMZ
Additional authorized common shares 13,200,000

During the current reporting period, NMZ sold common shares through its Shelf Offering at a weighted average premium to its NAV per common share as shown in the accompanying table.

NMZ
Common shares sold through Shelf Offering 7,452,533
Weighted average premium to NAV per common share sold 1.57 %

Refer to Notes to Financial Statements, Note 4 – Fund Shares, Common Shares Equity Shelf Programs and Offering Costs for further details of Shelf offerings and the Fund's transactions.

COMMON SHARE REPURCHASES

During August 2016, the Funds' Board of Trustees reauthorized an open-market share repurchase program, allowing each Fund to repurchase an aggregate of up to approximately 10% of its outstanding shares.

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) (formerly known as Nuveen Enhanced AMT-Free Municipal Credit Opportunities Fund)

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. 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.

To the Board of Trustees and Shareholders of Nuveen AMT-Free Municipal Credit Income Fund (formerly known as Nuveen Enhanced AMT-Free Municipal Credit Opportunities Fund) Nuveen Municipal Credit Income Fund (formerly known as Nuveen Enhanced Municipal Credit Opportunities Fund) Nuveen Municipal High Income Opportunity Fund:

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Nuveen AMT-Free Municipal Credit Income Fund, Nuveen Municipal Credit Income Fund, and Nuveen Municipal High Income Opportunity Fund (the "Funds") as of October 31, 2016, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, the statements of cash flows for the year then ended, and the financial highlights for each of the years in the three-year period then ended. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for the periods presented through October 31, 2013 were audited by other auditors whose report dated December 27, 2013 expressed an unqualified opinion on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2016, by correspondence with the custodian and brokers or other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Funds as of October 31, 2016, the results of their operations for the year then ended, the changes in their net assets for each of the years in the two-year period then ended, their cash flows for the year then ended, and the financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles.

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

(9) On January 7, 2015, the Fund’s Adviser determined it was unlikely that this borrower would fulfill its entire obligation on this security, and therefore reduced the security’s interest rate of accrual from 7.125% to 5.700% and again on November 11, 2015, further reduced the security’s interest rate of accrual from 5.700% to 4.275%.

During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund surrendered its Las Vegas Monorail Project Revenue Bonds, First Tier, Series 2000 and in turn received two senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15, 2019 and the second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing on July 15, 2055. The Fund is not accruing income for either senior interest corporate bond.
(12) A copy of the most recent financial statements for these investment companies can be obtained directly from the Securities and Exchange Commission on its website at http://www.sec.gov.

(1) All percentages shown in the Portfolio of Investments are based on net assets applicable to common shares unless otherwise noted.
(2) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3) The ratings disclosed are the lowest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4) As of, or subsequent to, the end of the reporting period, this security is non-income producing. Non-income producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has ceased accruing additional income on the Fund’s records.
(5) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest. Certain bonds backed by U.S. Government or agency securities are regarded as having an implied rating equal to the ratings of such securities.
(6) Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.
(7) The coupon for this security increased 0.25% effective January 1, 2016 and increased an additional 0.25% effective May 11, 2016.
(8) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.
(9) On July 28, 2015, the Fund’s Adviser determined it was unlikely that this borrower would fulfill its entire obligation on this security, and therefore reduced the security’s interest rate of accrual from 6.125% to 3.675%. On December 9, 2015, the Fund’s Adviser determined it was likely that this borrower would fulfill a greater portion of its obligation on this security, and therefore increased the security’s interest rate of accrual from 3.675% to 4.900%.
(10) On June 1, 2013, the Fund’s Adviser determined it was unlikely that this borrower would fulfill its entire obligation on the security, and therefore reduced the security’s interest rate of accrual from 7.250% to 1.813%.

(11) Step-up coupon. The rate shown is the coupon as of the end of the reporting period.

(13) On May 7, 2015, the Fund’s Adviser determined it was unlikely that this borrower would fulfill its entire obligation on this security, and therefore reduced the security’s interest rate of accrual from 5.250% to 2.100%.
(14) On July 1, 2014, the Fund’s Adviser determined it was unlikely that this borrower would fulfill its entire obligation on this security, and therefore reduced the security’s interest rate of accrual from 6.000% to 4.200%.
(15) On September 1, 2013, the Fund’s Adviser determined it was unlikely that this borrower would fulfill its entire obligation on this security, and therefore reduced the security’s interest rate of accrual from 6.250% to 4.688%.
(16) On November 28, 2011, AMR Corp. (“AMR”), the parent company of American Airlines Group, Inc. (“AAL”) filed for federal bankruptcy protection. On December 9, 2013, AMR emerged from federal bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement established to meet AMR’s unsecured bond obligations, the bondholders, including the Fund, received a distribution of AAL preferred stock which was converted to AAL common stock over a 120-day period. Every 30 days, a quarter of the preferred stock was converted to AAL common stock based on the 5-day volume-weighted average price and the amount of preferred shares tendered during the optional preferred conversion period.

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

General Information

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

Nuveen AMT-Free Municipal Credit Income Fund (NVG) ("AMT-Free Credit Income (NVG)") (formerly known as Nuveen Enhanced AMT-Free Municipal Credit Opportunities Fund ("Enhanced AMT-Free Credit Opportunities") and prior to the reorganization as further described below Nuveen Dividend Advantage Municipal Income Fund)
Nuveen Municipal Credit Income Fund (NZF) ("Credit Income (NZF)") (formerly known as Nuveen Enhanced Municipal Credit Opportunities Fund ("Enhanced Credit Opportunities") and prior to the reorganization as further described below Nuveen Dividend Advantage Municipal Fund 3)
Nuveen Municipal High Income Opportunity Fund (NMZ) ("High Income Opportunity (NMZ)")

The Funds are registered under the Investment Company Act of 1940, as amended, as diversified closed-end management investment companies. Common shares of each Fund are traded on the NYSE (common shares of each Fund were formerly traded on the NYSE MKT). AMT-Free Credit Income (NVG), Credit Income (NZF) and High Income Opportunity (NMZ) were organized as Massachusetts business trusts on July 12, 1999, March 21, 2001 and October 8, 2003, respectively.

The end of the reporting period for the Funds is October 31, 2016, and the period covered by these Notes to Financial Statements is the fiscal year ended October 31, 2016 (the "current fiscal period").

Effective April 11, 2016, in conjunction with their reorganizations, AMT-Free Credit Income (NVG) changed its name from Nuveen Dividend Advantage Municipal Income Fund to Nuveen Enhanced AMT-Free Municipal Credit Opportunities Fund, and Credit Income (NZF) changed its name from Nuveen Dividend Advantage Municipal Fund 3 to Nuveen Enhanced Municipal Credit Opportunities Fund.

Effective December 28, 2016, subsequent to the end of the reporting period, AMT-Free Credit Income (NVG) changed its name from Enhanced AMT-Free Credit Opportunities and Credit Income (NZF) changed its name from Enhanced Credit Opportunities.

Investment Adviser The Funds' investment adviser is Nuveen Fund Advisors, LLC (the "Adviser"), a wholly-owned subsidiary of Nuveen Investments, Inc. ("Nuveen"). Nuveen is an operating division of TIAA Global Asset Management. 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.

Investment Objectives and Principal Investment Strategies Each Fund seeks 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.

Effective August 5, 2016, Credit Income (NZF) has added an investment policy to limit the amount of securities subject to the alternative minimum tax ("AMT") to no more than 20% of the Fund's managed assets (as defined in Note 7 – Management Fees and Other Transactions with Affiliates). In addition, effective August 5, 2016, High Income Opportunity (NMZ) changed its investment policy to limit the amount of securities subject to the AMT to no more than 20% (30% prior to August 5, 2016) of the Fund's managed assets.

Fund Reorganizations Effective prior to the opening of business on April 11, 2016, certain funds were reorganized into two, larger national Funds included in this report (each a "Reorganization" and collectively, the "Reorganizations") as follows:

Target Funds Acquiring Fund
Nuveen Municipal Opportunity Fund, Inc. (NIO) Enhanced AMT-Free Credit Opportunities (NVG)*
("Opportunity (NIO)")
Nuveen Quality Municipal Fund, Inc. (NQI)
("Quality (NQI)")
Nuveen Quality Income Municipal Fund, Inc. (NQU)
("Quality Income (NQU)")
  • Fund name subsequently changed as described previously.
Target Funds Acquiring Fund
Nuveen Premium Income Municipal Fund 4, Inc. (NPT) Enhanced Credit Opportunities (NZF)*
("Premium Income 4 (NPT)")
Nuveen Dividend Advantage Municipal Fund 2 (NXZ)
("Dividend Advantage 2 (NXZ)")
Nuveen Municipal Advantage Fund, Inc. (NMA)
("Municipal Advantage (NMA)")
  • Fund name subsequently changed as described previously.

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

Upon the closing of each reorganization, the Target Funds transferred their assets to the Acquiring Funds in exchange for common and preferred shares of the Acquiring Funds and the assumption by the Acquiring Funds of the liabilities of the Target Funds. The Target Funds were then liquidated, dissolved and terminated in accordance with their Declaration of Trust. Shareholders of the Target Funds became shareholders of the Acquiring Funds. Holders of common shares of the Target Funds received newly issued common shares of the Acquiring Funds, the aggregate net asset value ("NAV") of which is equal to the aggregate NAV of the common shares of the Target Funds held immediately prior to the Reorganizations (including for this purpose fractional Acquiring Fund shares to which shareholders were entitled). Holders of preferred shares of the Target Funds receive on a one-for-one basis newly issued preferred shares of the Acquiring Fund, in exchange for preferred shares of the Target Funds held immediately prior to the Reorganizations. Details of the Reorganizations are further described in Note 9 – Fund Reorganizations.

Significant Accounting Policies Each Fund is an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 946, "Financial Services-Investment Companies." The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

Investment Transactions Investment transactions are recorded on a trade date basis. Realized gains and losses from investment transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Funds have earmarked securities in their portfolios with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments.

As of the end of the reporting period, the following Funds' outstanding when-issued/delayed delivery purchase commitments were as follows:

Credit High Income
Income Opportunities
(NVG ) (NMZ )
Outstanding when-issued/delayed delivery purchase commitments $ 17,871,879 $ 7,836,000

Investment Income Dividend Income is recorded on the ex-dividend date. Investment income, which reflects the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also reflects paydown gains and losses, if any.

NUVEEN 137

Notes to Financial Statements (continued)

Professional Fees Professional fees presented on the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment or to pursue other claims or legal actions on behalf of Fund shareholders. If a refund is received for workout expenditures paid in a prior reporting period, such amounts will be recognized as "Legal fee refund" on the Statement of Operations.

Dividends and Distributions to Common Shareholders Dividends from net investment income, if any, are declared monthly. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders at least annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.

Distributions to common shareholders of net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount 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.

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 3 – Portfolio Securities and Investments in Derivatives.

Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets applicable to common shares from operations during the reporting period. Actual results may differ from those estimates.

  1. Investment Valuation and Fair Value Measurements

The fair valuation input levels as described below are for fair value measurement purposes.

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, prepayment speeds, credit risk, etc.).
Level 3 – Prices are determined using significant unobservable inputs (including management's assumptions in determining the fair value of investments).

138 NUVEEN

Prices of fixed income securities are provided by an independent pricing service ("pricing service") approved by the Funds' Board of Trustees (the "Board"). The pricing service establishes a security's fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor's credit characteristics considered relevant. These securities are generally classified as Level 2. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity, provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs.

Prices of swap contracts are also provided by a pricing service approved by the Board using the same methods as described above and are generally classified as Level 2.

Investments in investment companies are valued at their respective NAVs 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.

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.

The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of each Fund's fair value measurements as of the end of the reporting period:

Notes to Financial Statements (continued)

The Board is responsible for the valuation process and has appointed the oversight of the daily valuation process to the Adviser's Valuation Committee. The Valuation Committee, pursuant to the valuation policies and procedures adopted by the Board, is responsible for making fair value determinations, evaluating the effectiveness of the Funds' pricing policies and reporting to the Board. The Valuation Committee is aided in its efforts by the Adviser's dedicated Securities Valuation Team, which is responsible for administering the daily valuation process and applying fair value methodologies as approved by the Valuation Committee. When determining the reliability of independent pricing services for investments owned by the Funds, the Valuation Committee, among other things, conducts due diligence reviews of the pricing services and monitors the quality of security prices received through various testing reports conducted by the Securities Valuation Team.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making a fair value determination, based on the facts and circumstances specific to the portfolio instrument. Fair value determinations generally will be derived as follows, using public or private market information:

(i) If available, fair value determinations shall be derived by extrapolating from recent transactions or quoted prices for identical or comparable securities.
(ii) If such information is not available, an analytical valuation methodology may be used based on other available information including, but not limited to: analyst appraisals, research reports, corporate action information, issuer financial statements and shelf registration statements. Such analytical valuation methodologies may include, but are not limited to: multiple of earnings, discount from market value of a similar freely-traded security, discounted cash flow analysis, book value or a multiple thereof, risk premium/yield analysis, yield to maturity and/or fundamental investment analysis.

The purchase price of a portfolio instrument will be used to fair value the instrument only if no other valuation methodology is available or deemed appropriate, and it is determined that the purchase price fairly reflects the instrument's current value.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such testing and fair valuation occurrences are reported to the Board.

  1. Portfolio Securities and Investments in Derivatives

Portfolio Securities

Inverse Floating Rate Securities Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond (referred to as an "Underlying Bond"), typically with a fixed interest rate, into a special purpose tender option bond ("TOB") trust (referred to as the "TOB Trust") created by or at the direction of one or more Funds. In turn, the TOB Trust issues (a) floating rate certificates (referred to as "Floaters") in face amounts equal to some fraction of the Underlying Bond's par amount or market value, and (b) an inverse floating rate certificate (referred to as an "Inverse Floater") that represents all remaining or residual interest in the TOB Trust. Floaters typically pay short-term tax-exempt interest rates to third parties who are also provided a right to tender their certificate and receive its par value, which may be paid from the proceeds of a remarketing of the Floaters, by a loan to the TOB Trust from a third party liquidity provider ("Liquidity Provider"), or by the sale of assets from the TOB Trust. The Inverse Floater is issued to a long term investor, such as one or more of the Funds. The income received by the Inverse Floater holder varies inversely with the short-term rate paid to holders of the Floaters, and in most circumstances the Inverse Floater holder bears substantially all of the Underlying Bond's downside investment risk and also benefits disproportionately from any potential appreciation of the Underlying Bond's value. The value of an Inverse Floater will be more volatile than that of the Underlying Bond because the interest rate is dependent on not only the fixed coupon rate of the Underlying Bond but also on the short-term interest paid on the Floaters, and because the Inverse Floater essentially bears the risk of loss (and possible gain) of the greater face value of the Underlying Bond.

The Inverse Floater held by a Fund gives the Fund the right to (a) cause the holders of the Floaters to tender their certificates at par (or slightly more than par in certain circumstances), and (b) have the trustee of the TOB Trust (the "Trustee") transfer the Underlying Bond held by the TOB Trust to the Fund, thereby collapsing the TOB Trust.

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").

140 NUVEEN

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.

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:

Credit Credit High Income
Income Income Opportunity
Floating Rate Obligations Outstanding (NVG ) (NZF ) (NMZ )
Floating rate obligations: self-deposited Inverse Floaters $ 209,060,000 $ 85,161,000 $ 136,260,000
Floating rate obligations: externally-deposited Inverse Floaters 168,510,000 69,094,000 185,900,000
Total $ 377,570,000 $ 154,255,000 $ 322,160,000

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

Credit Credit High Income
Income Income Opportunity
Self-Deposited Inverse Floaters (NVG ) (NZF ) (NMZ )
Average floating rate obligations outstanding $ 216,451,716 $ 133,081,856 $ 66,603,525
Average annual interest rate and fees 0.88 % 0.85 % 1.06 %

TOB Trusts are supported by a liquidity facility provided by a Liquidity Provider pursuant to which the Liquidity Provider agrees, in the event that Floaters are (a) tendered to the Trustee for remarketing and the remarketing does not occur, or (b) subject to mandatory tender pursuant to the terms of the TOB Trust agreement, to either purchase Floaters or to provide the Trustee with an advance from a loan facility to fund the purchase of Floaters by the TOB Trust. In certain circumstances, the Liquidity Provider may otherwise elect to have the Trustee sell the Underlying Bond to retire the Floaters that were tendered and not remarketed prior to providing such a loan. In these circumstances, the Liquidity Provider remains obligated to provide a loan to the extent that the proceeds of the sale of the Underlying Bond are not sufficient to pay the purchase price of the Floaters.

The size of the commitment under the loan facility for a given TOB Trust is at least equal to the balance of that TOB Trust's outstanding Floaters plus any accrued interest. In consideration of the loan facility, fee schedules are in place and are charged by the Liquidity Provider(s). Any loans made by the Liquidity Provider will be secured by the purchased Floaters held by the TOB Trust. Interest paid on any outstanding loan balances will be effectively borne by the Fund that owns the Inverse Floaters of the TOB Trust that has incurred the borrowing and may be at a rate that is greater than the rate that would have been paid had the Floaters been successfully remarketed.

As described above, any amounts outstanding under a liquidity facility are recognized as a component of "Floating rate obligations" on the Statement of Assets and Liabilities by the Fund holding the corresponding Inverse Floaters issued by the borrowing TOB Trust. As of the end of the reporting period, ATM-Free Credit Income (NVG) and High Income Opportunity (NMZ) had outstanding borrowings under such liquidity facilities in the amount of $586,225 and $6,928,796, respectively, which are recognized as a component of "Floating rate obligations" on the Statement of Assets and Liabilities. There were no loans outstanding under any such facilities for Credit Income (NZF) as of the end of the reporting period.

NUVEEN 141

Notes to Financial Statements (continued)

Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a "recourse arrangement" or "credit recovery swap") (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:

Credit Credit High Income
Income Income Opportunity
Floating Rate Obligations – Recourse Trusts (NVG ) (NZF ) (NMZ )
Maximum exposure to Recourse Trusts: self-deposited Inverse Floaters $ 86,845,000 $ 51,461,000 $ 69,575,000
Maximum exposure to Recourse Trusts: externally-deposited Inverse Floaters 77,405,000 33,719,000 176,150,000
Total $ 164,250,000 $ 85,180,000 $ 245,725,000

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

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

Interest Rate Swap Contracts Interest rate swap contracts involve a Fund's agreement with the counterparty to pay or receive a fixed rate payment in exchange for the counterparty receiving or paying a variable rate payment. Forward interest rate swap contracts involve a Fund's agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying the Fund a variable or fixed rate payment, the accruals for which would begin at a specified date in the future (the "effective date").

The amount of the payment obligation is based on the notional amount and the termination date of the contract. Interest rate swap contracts do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to the swap counterparty on such transactions is limited to the net amount of interest payments that the Fund is to receive.

Interest rate swap contracts are valued daily. Upon entering into an interest rate swap contract (and beginning on the effective date for a forward interest rate swap contract), a Fund accrues the fixed rate payment expected to be paid or received and the variable rate payment expected to be received or paid on the interest rate swap contracts on a daily basis, and recognizes the daily change in the fair value of the Fund's contractual rights and obligations under the contracts. For an over-the-counter ("OTC") swap that is not cleared through a clearing house ("OTC Uncleared"), the net amount recorded on these transactions, for each counterparty, is recognized on the Statement of Assets and Liabilities as a component of "Unrealized appreciation or depreciation on interest rate swaps (, net)."

Upon the execution of an OTC swap cleared through a clearing house ("OTC Cleared"), the Fund is obligated to deposit cash or eligible securities, also known as "initial margin," into an account at its clearing broker equal to a specified percentage of the contract amount. Cash deposited by the Fund to cover initial margin requirements on open swap contracts, if any, is recognized as a component of "Cash collateral at brokers" on the Statement of Assets and Liabilities. Investments in OTC Cleared swaps obligate the Fund and the clearing broker to settle monies on a daily basis

142 NUVEEN

representing changes in the prior day's "mark-to-market" of the swap contract. If the Fund has unrealized appreciation, the clearing broker will credit the Fund's account with an amount equal to the appreciation. Conversely, if the Fund has unrealized depreciation, the clearing broker will debit the Fund's account with an amount equal to the depreciation. These daily cash settlements are also known as "variation margin." Variation margin for OTC Cleared swaps is recognized as a receivable and/or payable for "Variation margin on swap contracts" on the Statement of Assets and Liabilities. Upon the execution of an OTC Uncleared swap, neither the Fund nor the counterparty is required to deposit initial margin as the trades are recorded bilaterally between both parties to the swap contract, and the terms of the variation margin are subject to a predetermined threshold negotiated by the Fund and the counterparty. Variation margin for OTC Uncleared swaps is recognized as a component of "Unrealized appreciation or depreciation on interest rate swaps (, net)" as described in the preceding paragraph.

The net amount of periodic payments settled in cash are recognized as a component of "Net realized gain (loss) from swaps" on the Statement of Operations, in addition to the net realized gain or loss recorded upon the termination of the swap contract. For tax purposes, payments expected to be received or paid on the swap contracts are treated as ordinary income or expense, respectively. Changes in the value of the swap contracts during the fiscal period are recognized as a component of "Change in net unrealized appreciation (depreciation) of swaps" on the Statement of Operations. In certain instances, payments are made or received upon entering into the swap contract to compensate for differences between the stated terms of the swap agreements and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). Payments received or made at the beginning of the measurement period, if any, are recognized as "Interest rate swaps premiums paid and/or received" on the Statement of Assets and Liabilities.

During the current fiscal period, AMT-Free Credit Income (NVG) continued to invest in forward interest rate swap contracts, as part of its duration management strategies, to help reduce price volatility risk to movements in U.S. interest rates relative to the Fund's benchmark.

The average notional amount of interest rate swap contracts outstanding during the current fiscal period was as follows:

Credit
Income
(NVG )

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

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

  1. Fund Shares

Common Shares

Common Shares Equity Shelf Programs and Offering Costs High Income Opportunity (NMZ) has filed a registration statement with the Securities and Exchange Commission ("SEC") authorizing the Fund to issue additional common shares through one or more equity shelf programs ("Shelf Offering"), which became effective with the SEC during the current and 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:

Common shares sold 7,452,533
Offering proceeds, net of offering costs $ 103,621,513 $ —

Costs incurred by the Fund in connection with its Shelf Offering were recorded as a deferred charge and recognized as a component of "Deferred offering costs" on the Statement of Assets and Liabilities. The deferred asset is reduced during the one-year period that additional shares are sold by reducing the proceeds from such sales and recognized as a component of "Proceeds from shelf offering, net of offering costs" on the Statement of Changes in Net Assets. Any remaining deferred charges at the end of the one-year life of the Shelf Offering period will be expensed accordingly, as well as any additional Shelf Offering costs the Fund may incur. As Shelf Offering costs are expensed they are recognized as a component of "Other expenses" on the Statement of Operations.

During the current reporting period, the Fund was authorized to issue an additional 5.5 million common shares under a new Shelf Offering.

Institutional MuniFund Term Preferred Shares The following Fund has issued and has outstanding Institutional MuniFund Term Preferred ("iMTP") Shares, with a $5,000 liquidation preference per share. iMTP Shares are issued via private placement and are not publicly available.

As of the end of the reporting period, details of iMTP Shares outstanding were as follows:

Fund Series Shares — Outstanding Preference
Credit Income (NZF) 2017 30,000 $ 150,000,000

The Fund is obligated to redeem its iMTP Shares by the date as specified in its offering document ("Term Redemption Date"), unless earlier redeemed by the Fund. iMTP Shares are subject to optional and mandatory redemption in certain circumstances. The iMTP Shares are not subject to redemption at the option of the Fund for approximately one year following the date of issuance, at which point the Fund may redeem at its option ("Optional Redemption Date") and any date thereafter. The Fund may be obligated to redeem certain amount of the iMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation preference per share plus any accumulated but unpaid dividends. The Term Redemption Date and Optional Redemption Date for the Fund's iMTP Shares are as follows:

Income
(NZF )
Average liquidation preference of iMTP Shares outstanding $ 150,000,000
Annualized dividend rate 1.06 %

iMTP Shares are subject to restrictions on transfer and may only be sold or transferred to "qualified institutional buyers". iMTP 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 established at the time of issuance. The fair value of iMTP Shares is expected to be approximately their liquidation preference so long as the fixed "spread" on the iMTP Shares remains roughly in line with the "spread" being demanded by investors on instruments having similar terms in the current market environment. In present market conditions, the Fund's Adviser has determined that the fair value of iMTP 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 iMTP Shares is recorded as a liability and recognized as "Institutional MuniFund Term Preferred ("iMTP") Shares, at liquidation preference" on the Statement of Assets and Liabilities.

Dividends on the iMTP Shares (which are treated as interest payments for financial reporting purposes) are set weekly. Unpaid dividends on iMTP Shares are recognized as a component of "Interest payable" on the Statement of Assets and Liabilities, when applicable. Dividends accrued on iMTP Shares are recognized as a component of "Interest expense and amortization of offering costs" on the Statement of Operations.

Costs incurred by the Fund in connection with its offering of iMTP Shares were recorded as a deferred charge, which are amortized over the life of the shares and recognized as components of "Deferred offering costs" on the Statement of Assets and Liabilities and "Interest expense and amortization of offering costs" on the Statement of Operations.

Variable Rate MuniFund Term Preferred Shares The following Funds have issued and have outstanding Variable Rate MuniFund Term Preferred ("VMTP") Shares, with a $100,000 liquidation preference per share. VMTP Shares are issued via private placement and are not publicly available.

As of the end of the reporting period, VMTP Shares outstanding, at liquidation preference, for each Fund were as follows:

Fund Series Outstanding Liquidation — Preference

High Income Opportunity (NMZ) 2018 870 $ 87,000,000
  • Includes VMTP Shares issued in connection with its Reorganization.

During the current fiscal period, Credit Income (NZF) refinanced all of its outstanding Series 2017 VMTP Shares with the issuance of new Series 2019 VMTP Shares. In conjunction with this refinancing Credit Income (NZF) issued an additional $255,000,000 Series 2019 VMTP Shares at liquidation preference to be invested in accordance with its investment policies.

Each Fund is obligated to redeem its VMTP Shares by the date as specified in its offering document ("Term Redemption Date"), unless earlier redeemed by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances. The VMTP Shares may be redeemed at the option of each Fund, subject to payment of premium for approximately one year 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. Each Fund may be obligated to redeem a certain amount of the VMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The Term Redemption Date and Premium Expiration Date for each Fund's VMTP Shares are as follows:

VMTP Shares are subject to restrictions on transfer, generally do not trade, and market quotations are generally not available. VMTP 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 established at the time of issuance. The fair value of VMTP Shares is expected to be approximately their liquidation preference so long as the fixed "spread" on the VMTP Shares remains roughly in line with the "spread" being demanded by investors on instruments having similar terms in the current market environment. In present market conditions, the Funds' Adviser has determined that fair value of VMTP 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 VMTP Shares is a liability and is recognized as "Variable Rate MuniFund Term Preferred ("VMTP") Shares, at liquidation preference" on the Statement of Assets and Liabilities.

Dividends on the VMTP shares (which are treated as interest payments for financial reporting purposes) are set weekly. Unpaid dividends on VMTP Shares are recognized as a component of "Interest payable" on the Statement of Assets and Liabilities. Dividends accrued on VMTP Shares are recognized as a component of "Interest expense and amortization of offering costs" on the Statement of Operations.

Credit Income (NZF) incurred offering costs of $260,000 in connection with its issuance of Series 2019 VMTP Shares, which was expensed as incurred and is recognized as a component of "Interest expense and amortization of offering costs" on the Statement of Operations.

  • VRDP Shares issued in connection with the Reorganization.

During the current reporting period, AMT-Free Credit Income (NVG) issued an additional $180,000,000 Series 4 VRDP Shares at liquidation preference, which will be used to invest in additional municipal securities in accordance with its investment objectives and policies.

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 of 0.10% on the aggregate principal amount of all VRDP Shares outstanding. Each Fund's VRDP Shares have successfully remarketed since issuance.

Series 1 and Series 4 VRDP shares in AMT-Free Credit Income (NVG) are considered to be Special Rate Period VRDP. Special Rate Period VRDP are sold to banks with an initial special short/intermediate rate period (typically three years) with a dividend rate set at a fixed spread to a specified short-term municipal index rate calculated weekly. Weekly remarketings do not take place during the initial special rate period. After the initial special rate period, Special Rate Period VRDP Shares will revert back to traditional VRDP Shares with dividends set at weekly remarketings, with an option to sell the shares to a designated liquidity provider, unless the Board approves another 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.

Notes to Financial Statements (continued)

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.

  1. 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.

As of October 31, 2016, the cost and unrealized appreciation (depreciation) of investments (excluding investments in derivatives, where applicable), as determined on a federal income tax basis, were as follows:

Credit Credit High Income
Income Income Opportunity
(NVG ) (NZF ) (NMZ )
Cost of investments $ 4,502,548,019 $ 3,134,166,034 $ 793,520,582
Gross unrealized:
Appreciation 490,204,549 358,566,077 102,701,254
Depreciation (25,142,226 ) (24,187,346 ) (36,944,620 )
Net unrealized appreciation (depreciation) of investments $ 465,062,323 $ 334,378,731 $ 65,756,634

Permanent differences, primarily due to federal taxes paid, nondeductible offering costs, nondeductible reorganization expenses, taxable market discount, tender option bond adjustments, and expiration of capital loss carryforwards, resulted in reclassifications among the Funds' components of common share net assets as of October 31, 2016, the Funds' tax year end, as follows:

Credit Credit High Income

  1. 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:

AMT-Free Credit Income (NVG) **
Credit Income (NZF) **
Average Daily Managed Assets* Fund-Level Fee
For the first $125 million 0.4500 %
For the next $125 million 0.4375
For the next $250 million 0.4250
For the next $500 million 0.4125
For the next $1 billion 0.4000
For managed assets over $2 billion 0.3750

** Effective for the period November 1, 2015 through April 10, 2016.

Notes to Financial Statements (continued)

Effective August 1, 2016, the annual Fund-level fee, payable monthly, for the following Fund is calculated according to the following schedule:

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

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

Complex-Level Managed Asset Breakpoint Level* Effective Rate at Breakpoint Level
$55 billion 0.2000 %
$56 billion 0.1996
$57 billion 0.1989
$60 billion 0.1961
$63 billion 0.1931
$66 billion 0.1900
$71 billion 0.1851
$76 billion 0.1806
$80 billion 0.1773
$91 billion 0.1691
$125 billion 0.1599
$200 billion 0.1505
$250 billion 0.1469
$300 billion 0.1445
  • For the complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the funds' use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust's issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen 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 $23billion) 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. As of October 31, 2016, the complex-level fee for each Fund was 0.1610%.

The Adviser has agreed to implement a fee waiver which would begin on the effective date of the New Investment Management Agreement (the "Agreement") and will be phased out over the first year following the effective date of the Agreement. The waiver would be applied according to the following schedule and annual rates: (i) 0.05% of managed assets for the first 90 day period following the effective date of the Agreement; (ii) 0.0375% of managed assets for the 91st through 180th day period following the effective date of the Agreement; (iii) 0.025% of managed assets for the 181st through 270th day period following the effective date of the Agreement; and (iv) 0.0125% of managed assets for the 271st through 365th day period following the effective date of the Agreement. The fee waiver agreement may not be discontinued prior to the expiration of the one-year period unless authorized by the Board of the Acquiring Funds or the Acquiring Funds' Agreement terminates. The purpose of the fee waiver is to phase in the new management fee over a period of one year. The fee waiver is not expected to be continued.

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

Each Fund is permitted to purchase or sell securities from or to certain other funds managed by the Adviser ("inter-fund trade") under specified conditions outlined in procedures adopted by the Board. These procedures have been designed to ensure that any inter-fund trade of securities by the Fund from or to another fund that is, or could be, considered an affiliate of the Fund under certain limited circumstances by virtue of having a common

152 NUVEEN

investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 of the 1940 Act. Further, as defined under these procedures, each inter-fund trade is effected at the current market price as provided by an independent pricing service. Unsettled inter-fund trades as of the end of the reporting period are recognized as a component of "Receivable for investments sold" and/or "Payable for investments purchased" on the Statement of Assets and Liabilities, when applicable.

During the current fiscal period, the Funds engaged in inter-fund trades pursuant to these procedures as follows:

Credit Credit High Income
Income Income Opportunity
Inter-Fund Trades (NVG ) (NZF ) (NMZ )
Purchases $ 579,070 $ 3,113,533 $
Sales 10,848,255 23,717,020
  1. Borrowing Arrangements

Uncommitted Line of Credit During the current fiscal period, the Funds participated in an unsecured bank line of credit ("Unsecured Credit Line") under which outstanding balances would bear interest at a variable rate. On December 31, 2015, (the only date utilized during the current fiscal period) the Funds borrowed the following amounts from the Unsecured Credit Line, each at an annualized interest rate of 1.68% on their respective outstanding balance.

Credit Credit High Income
Income Income Opportunity
(NVG ) (NZF ) (NMZ )
Outstanding balance at December 31, 2015 $ 3,747,388 $ 8,771,021 $ 14,288,455

Committed Line of Credit The Funds, along with certain other funds managed by the Adviser ("Participating Funds"), have established a 364-day, approximately $2.5 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. A large portion of this facility's capacity (and its associated costs as described below) is currently dedicated for use by a small number of Participating Funds, which does not include any of the Funds covered by this shareholder report. The remaining capacity under the facility (and the corresponding portion of the facility's annual costs) is separately dedicated to most of the other open-end funds in the Nuveen fund family, along with a number of Nuveen closed-end funds, including all of the Funds covered by this shareholder report. The credit facility expires in July 2017 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 1.25% per annum or (b) the Fed Funds rate plus 1.25% per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of "Other expenses" on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility's aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund.

During the current fiscal period, all of the Funds utilized this facility.

The Funds' average daily balance outstanding and average annual interest rate during the utilization period were as follows:

Credit Credit High Income
Income Income Opportunity
(NVG ) (NZF ) (NMZ )
Average daily balance outstanding $ 21,428,571 $ 24,471,154 $ 23,691,107
Average annual interest rate 1.73 % 1.74 % 1.77 %

Borrowings outstanding as of the end of the reporting period are recognized as "Borrowings" on the Statement of Assets and Liabilities.

  1. Fund Reorganizations

The Reorganizations were structured to qualify as tax-free reorganizations under the Internal Revenue Code for federal income tax purposes, and the Target Funds' shareholders recognized no gain or loss for federal income tax purposes as a result. Prior to the closing of each of the Reorganizations, the Target Funds distributed all of their net investment income and capital gains, if any. Such a distribution may be taxable to the Target Funds' shareholders for federal income tax purposes.

Investments The cost, fair value and net unrealized appreciation (depreciation) of the investments of the Target Funds as of the date of the Reorganizations, were as follows:

Opportunity Quality Quality — Income
(NIO ) (NQI ) (NQU )
Cost of investments $ 2,087,589,886 $ 764,389,291 $ 1,064,222,983
Fair value of investments 2,300,474,439 849,318,429 1,199,621,673
Net unrealized appreciation (depreciation) of investments 212,884,553 84,929,138 135,398,690

Net unrealized appreciation (depreciation) of investments 101,744,189 75,493,445 94,001,355

For financial reporting purposes, assets received and shares issued by the Acquiring Funds were recorded at fair value; however, the cost basis of the investments received from the Target Funds were carried forward to align ongoing reporting of the Acquiring Funds' 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 Reorganizations were as follows:

Opportunity Quality Quality — Income

Pro Forma Results of Operations (Unaudited) The beginning of the Target Funds' current fiscal period was November 1, 2015. Assuming the Reorganizations had been completed on November 1, 2015, the beginning of the Acquiring Funds' current fiscal period, the pro forma results of operations for the current fiscal period, are as follows:

Credit Credit

Net realized and unrealized gains (losses) 96,201,273 76,864,941
Change in net assets resulting from operations 306,744,154 196,841,543

NUVEEN 155

Notes to Financial Statements (continued)

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

Cost and Expenses In connection with the Reorganizations, the Acquiring Fund incurred certain associated costs and expenses. Such amounts were included as components of "Accrued other expenses" on the Statement of Assets and Liabilities and "Reorganization expenses" on the Statement of Operations.

  1. Subsequent Events

Fund information As mentioned in Note 1- General Information and Significant Accounting Policies, AMT-Free Credit Income (NVG) changed its name from Enhanced AMT-Free Credit Opportunities and Credit Income (NZF) changed its name from Enhanced Credit Opportunities, effective December 28, 2016.

Variable Rate Demand Preferred Shares Subsequent to the end of the reporting period, AMT-Free Credit Income (NVG) refinanced all of its outstanding Series 3 VRDP Shares with the issuance of new Series 5 and Series 6 VRDP Shares.

Glossary of Terms Used in this Report

Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have "failed," with current holders receiving a formula-based interest rate until the next scheduled auction.
Average Annual Total Return: This is a commonly used method to express an investment's performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment's actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.
Duration: Duration is a measure of the expected period over which a bond's principal and interest will be paid, and consequently is a measure of the sensitivity of a bond's or bond fund's value to changes when market interest rates change. Generally, the longer a bond's or fund's duration, the more the price of the bond or fund will change as interest rates change.
Effective Leverage: Effective leverage is a fund's effective economic leverage, and includes both regulatory leverage (see leverage) and the leverage effects of certain derivative investments in the fund's portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.
Forward Interest Rate Swap: A contractual agreement between two counterparties under which one party agrees to make periodic payments to the other for an agreed period of time based on a fixed rate, while the other party agrees to make periodic payments based on a floating rate of interest based on an underlying index. Alternatively, both series of cash flows to be exchanged could be calculated using floating rates of interest but floating rates that are based upon different underlying indexes.
Gross Domestic Product (GDP): The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.
Industrial Development Revenue Bond (IDR): A unique type of revenue bond issued by a state or local government agency on behalf of a private sector company and intended to build or acquire factories or other heavy equipment and tools.
Inverse Floating Rate Securities: Inverse floating rate securities, also known as inverse floaters or tender option bonds (TOBs), are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond's par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an "inverse floater") to an investor (such as a fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates' holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond's downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond's value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.
Leverage: Leverage is created whenever a fund has investment exposure (both reward and/or risk) equivalent to more than 100% of the investment capital.

158 NUVEEN

Lipper General & Insured Leveraged Municipal Debt Funds Classification Average: Calculated using the returns of all closed-end funds in this category. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charges.
Lipper High-Yield Municipal Debt Funds Classification Average: Calculated using the returns of all closed-end funds in this category. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charges.
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 9/12/16 and thereafter the returns of an 60%/40% blend of the S&P Municipal Bond Investment Grade Index and the S&P Municipal Bond High Yield Index, respectively. The S&P Municipal Bond Index is an unmanaged, market value-weighted index designed to measure the performance of tax-exempt municipal bonds. The S&P Municipal Bond Investment Grade Index is an unmanaged, market value-weighted index designed to measure the performance of tax-exempt municipal bonds rated investment grade by Standard & Poor's, Moody's and/or Fitch. The S&P Municipal Bond High Yield Index is an unmanaged, market value-weighted index designed to measure the performance of the tax-exempt, high yield municipal bonds. Index returns assume compounding and do not include the effects of any fees or expenses.
Net Asset Value (NAV) Per Share: A fund's Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund's Net Assets divided by its number of shares outstanding.
Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond's credit rating and thus its value.
Regulatory Leverage: Regulatory leverage consists of preferred shares issued by or borrowings of a fund. Both of these are part of a fund's capital structure. Regulatory leverage is subject to asset coverage limits set in the Investment Company Act of 1940.
S&P Municipal Bond High Yield Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment grade U.S. high yield municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
S&P Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment-grade U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
Total Investment Exposure: Total investment exposure is a fund's assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a fund's use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust's issuance of floating rate securities.
Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

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 pro3t, 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 as -set 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 imme -diately prior to the purchase date. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.

Flexible

You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change. You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan. The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

Annual Investment Management Agreement Approval Process (Unaudited)

The Board of Trustees of each Fund (the "Board," and each Trustee a "Board Member" ), including the Board Members who are not parties to the Funds' advisory or sub-advisory agreements or "interested persons" of any such parties (the "Independent Board Members" ), is responsible for overseeing the performance of the investment adviser and sub-adviser to the respective Fund and determining whether to continue such Fund's advisory agreement (the "Investment Management Agreement") between the Fund and Nuveen Fund Advisors, LLC (the "Adviser" ) and the sub-advisory agreement (the "Sub-Advisory Agreement" and, together with the Investment Management Agreement, the "Advisory Agreements" ) between the Adviser and Nuveen Asset Management, LLC (the "Sub-Adviser" ). Following an initial term with respect to each Fund upon its commencement of operations, the Board reviews each Investment Management Agreement and Sub-Advisory Agreement on behalf of each Fund and votes to determine whether the respective Advisory Agreement should be renewed. Accordingly, at an in-person meeting held on May 24-26, 2016 (the "May Meeting" ), the Board, including a majority of the Independent Board Members, considered and approved the existing Advisory Agreements for the Funds.

During the year, the Board and its Committees met regularly to receive materials and discuss a variety of topics impacting the Funds including, among other things, overall market conditions and market performance, Fund investment performance, brokerage execution, valuation of securities, compliance matters, securities lending, leverage matters, risk management and ongoing initiatives. The Board had established several standing Committees, including the Open-end Fund Committee and Closed-end Fund Committee which permit the Board Members to delve further into the topics particularly relevant to the respective product line and enhance the Board's effectiveness and oversight of the Funds. The Board also seeks to meet with the Sub-Adviser and its investment team at least once over a multiple year rotation through site visits. The information and knowledge the Board gained throughout the year from the Board and Committee meetings, site visits and the related materials were relevant to the Board's evaluation of the Advisory Agreements, and the Board took such information into account in its review of the Advisory Agreements.

In addition to the materials received throughout the year, the Board received additional materials prepared specifically for its annual review of the Advisory Agreements in response to a request by independent legal counsel on behalf of the Independent Board Members. The materials addressed a variety of topics, including a description of the services provided by the Adviser and the Sub-Adviser (each, a "Fund Adviser" ); a review of fund performance with a detailed focus on any performance outliers; an analysis of the investment teams; an analysis of the fees and expense ratios of the Funds, including information comparing such fees and expenses to that of peer groups; an assessment of shareholder services for the Funds and of the performance of certain service providers; a review of initiatives instituted or continued during the past year; and a review of premium/discount trends and leverage management as well as information regarding the profitability of the Fund Advisers, the compensation of portfolio managers, and compliance and risk matters.

As part of its annual review, the Board held a separate meeting on April 12-13, 2016 to review the Funds' investment performance and consider an analysis by the Adviser of the Sub-Adviser examining, among other things, the team's assets under management, investment performance, investment approach, and the stability and structure of the Sub-Adviser's organization and investment team. During the review, the Independent Board Members requested and received additional information from management. Throughout the year and throughout their review of the Advisory Agreements, the Independent Board Members were assisted by independent legal counsel. The Independent Board Members met separately with independent legal counsel without management present and received a memorandum from such counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements. The Independent Board Members' review of the Advisory Agreements reflected an ongoing process that incorporated the information and considerations that occurred over the years, including the most recent year, as well as the information specifically furnished for the renewal process. In deciding to renew the Advisory Agreements, the Independent Board

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

Members did not identify a particular factor as controlling, but rather the decision reflected the comprehensive consideration of all the information presented. The following summarizes the principal factors, but not all the factors, the Board considered in its review of the Advisory Agreements and its conclusions.

A.
In evaluating the renewal of the Advisory Agreements, the Independent Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser's services provided to the respective Fund and the initiatives undertaken during the past year by the Adviser. The Board recognized the comprehensive set of services the Adviser provided to manage and operate the Nuveen funds, including (a) product management (such as setting dividends, positioning the product in the marketplace, maintaining and enhancing shareholder communications and reporting to the Board); (b) investment services (such as overseeing the Sub-Adviser and other service providers; analyzing investment performance and risks; overseeing risk management and disclosure; developing and interpreting investment policies; assisting in the development of products; helping to prepare financial statements and marketing disclosures; and overseeing trade execution); (c) fund administration (such as helping to prepare fund tax returns and complete other tax compliance matters; and helping to prepare regulatory filings and shareholder reports); (d) fund Board administration (such as preparing Board materials and organizing and providing assistance for Board meetings); (e) compliance (such as helping to devise and maintain the funds' compliance program and related testing); (f) legal support (such as helping to prepare registration statements and proxy statements, interpreting regulations and policies and overseeing fund activities); and (g) providing leverage management.
The Board reviewed the continued investment the Adviser had made in its business to continue to strengthen the breadth and quality of its services to the benefit of the Nuveen funds. The Board noted the Adviser's additional staffing in key areas that support the funds and the Board, including in investment services, operations, closed-end fund/structured products, fund governance, compliance, fund administration, product management, and information technology. Among the enhancements to its services, the Board recognized the Adviser's (a) expanded activities and support required as a result of regulatory developments, including in areas of compliance and reporting; (b) expanded efforts to support leverage management with a goal of seeking the most effective structure for fund shareholders given appropriate risk levels and regulatory constraints; (c) increased support for dividend management; (d) continued investment in its technical capabilities as the Adviser continued to build out a centralized fund data platform, enhance mobility and remote access capabilities, rationalize and upgrade software platforms, and automate certain regulatory liquidity determinations; (e) continued efforts to rationalize the product line through mergers, liquidations and re-positioning of Nuveen funds with the goal of increasing efficiencies, reducing costs, improving performance and addressing shareholder needs; (f) continued efforts to develop new lines of business designed to enhance the Nuveen product line and meet investor demands; and (g) continued commitment to enhance risk oversight, including the formation of the operational risk group to provide operational risk assessment, the access to platforms which provide better risk reporting to support investment teams, and the development of a new team to initially review new products and major product initiatives. The Board also recognized the Adviser's efforts to renegotiate certain fees of other service providers which culminated in reduced expenses for all funds for custody and accounting services without diminishing the breadth and quality of the services provided. The Board considered the Chief Compliance Officer's report regarding the Adviser's compliance program, the Adviser's continued development, execution and management of its compliance program, and the additions to the compliance team to support the continued growth of the Nuveen fund family and address regulatory developments.
The Board also considered information highlighting the various initiatives that the Adviser had implemented or continued during the year to enhance or support the closed-end fund product line. The Board noted the Adviser's continued efforts during 2015 (a) to rationalize the product line through mergers designed to help reduce product overlap, offer shareholders the potential for lower fees and enhanced investor acceptance, and address persistent discounts in the secondary market; (b) to oversee and manage leverage as the Adviser facilitated the rollover of existing facilities and conducted negotiations for

162 NUVEEN

improved terms and pricing to reduce leverage costs; (c) to conduct capital management services including share repurchases and/or share issuances throughout the year and monitoring market conditions to capitalize on such opportunities for the closed-end funds; and (d) to implement data-driven market analytics which, among other things, provided a better analysis of the shareholder base, enhanced the ability to monitor the closed-end funds versus peers and helped to understand trading discounts. The Board also considered the quality and breadth of Nuveen's investment relations program through which Nuveen seeks to build awareness of, and educate investors and financial advisers with respect to, Nuveen closed-end funds which may help to build an active secondary market for the closed-end fund product line.
As noted, the Adviser also oversees the Sub-Adviser who primarily provides the portfolio advisory services to the Funds. The Board recognized the skill and competency of the Adviser in monitoring and analyzing the performance of the Sub-Adviser and managing the sub-advisory relationship. The Board noted that the Adviser recommended the renewal of each Sub-Advisory Agreement.
Based on their review, the Independent Board Members found that, overall, the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement were satisfactory.
B. The Investment Performance of the Funds and Fund Advisers
The Board considered the long-term and short-term performance history of each Fund. As noted above, the Board reviewed fund performance at its quarterly meetings throughout the year and took into account the information derived from the discussions with representatives of the Adviser about fund performance at these meetings. The Board also considered the Adviser's analysis of fund performance with particular focus on any performance outliers and the factors contributing to such performance and any steps the investment team had taken to address performance concerns. The Board reviewed, among other things, each Fund's investment performance both on an absolute basis and in comparison to peer funds (the "Performance Peer Group" ) and to recognized and/or customized benchmarks (i.e., generally benchmarks derived from multiple recognized benchmarks) for the quarter, one-, three- and five-year periods ending December 31, 2015, as well as performance information reflecting the first quarter of 2016.
In evaluating performance information, the Board recognized the following factors may impact the performance data as well as the consideration to be given to particular performance data:
The performance data reflected a snapshot in time, in this case as of the end of the most recent calendar year or quarter. A different performance period, however, could generate significantly different results.
Long-term performance can be adversely affected by even one period of significant underperformance so that a single investment decision or theme had the ability to disproportionately affect long-term performance.
Shareholders evaluate performance based on their own holding period which may differ from the performance period reviewed by the Board, leading to different performance results.
The Board recognized the difficulty in establishing appropriate peer groups and benchmarks for certain funds. The Board noted that management classified the Performance Peer Groups as low, medium and high in relevancy and took the relevancy of the Performance Peer Group into account when considering the comparative performance data. If the Performance Peer Group differed somewhat from a fund, the Board recognized that the comparative performance data may be of limited value. The Board also recognized that each fund operated pursuant to its own investment objective(s), parameters and restrictions which may differ from that of the Performance Peer Group or benchmark and that these variations lead to differences in performance results. Further, for funds that utilized leverage, the Board understood that leverage during different periods could provide both benefits and risks to a portfolio as compared to an unlevered benchmark.

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

In addition to the foregoing, the Independent Board Members continued to recognize the importance of secondary market trading for the shares of closed-end funds. At the quarterly meetings as well as the May Meeting, the Independent Board Members (either at the Board level or through the Closed-end Fund Committee) reviewed, among other things, the premium or discount to net asset value of the Nuveen closed-end funds as of a specified date and over various periods as well as in comparison to the premium/discount average in their respective Lipper peer category. At the May Meeting and/or prior meetings, the Independent Board Members (either at the Board level or through the Closed-end Fund Committee) reviewed, among other things, an analysis by the Adviser of the key economic, market and competitive trends that affected the closed-end fund market and Nuveen closed-end funds and considered any actions proposed periodically by the Adviser to address trading discounts of certain closed-end funds, including, among other things, share repurchases, fund reorganizations, adjusting fund investment mandates and strategies, and increasing fund awareness to investors. The Independent Board Members considered the evaluation of the premium and discount levels of the closed-end funds to be a continuing priority in their oversight of the closed-end funds.
With respect to any Nuveen funds for which the Board has identified performance concerns, the Board monitors such funds closely until performance improves, discusses with the Adviser the reasons for such results, considers those steps necessary or appropriate to address such issues, and reviews the results of any efforts undertaken. The Board was aware, however, that shareholders chose to invest or remain invested in a fund knowing that the Adviser and the applicable sub-adviser manage the fund, knowing the fund's investment strategy and seeking exposure to that strategy (even if the strategy was "out of favor" in the marketplace) and knowing the fund's fee structure.
For Nuveen AMT-Free Municipal Credit Income Fund (the "AMT-Free Fund" ), the Board noted that, although the Fund ranked in its Performance Peer Group in the fourth quartile in the five-year period, the Fund ranked in the second quartile in the one- and three-year periods. In addition, the Fund outperformed its benchmark in the one-, three- and five-year periods. The Board determined that the Fund's performance had been satisfactory.
For Nuveen Municipal Credit Income Fund (the "Credit Income Fund") , the Board noted that, although the Fund ranked in the fourth quartile in the five-year period, the Fund ranked in the third quartile in the three-year period and the second quartile in the one-year period. The Fund also outperformed its benchmark in the one-, three- and five-year periods. The Board determined that the Fund's performance had been satisfactory.
For Nuveen Municipal High Income Opportunity Fund (the "High Income Fund" ), the Board noted that the Fund ranked in its Performance Peer Group in the second quartile for the one-year period and first quartile for the three- and five-year periods. The Fund also outperformed its benchmark in the one-, three- and five-year periods. The Board determined that the Fund's performance had been favorable.
C. Fees, Expenses and Profitability
1. Fees and Expenses
The Board evaluated the management fees and other fees and expenses of each Fund. The Board reviewed, among other things, the gross and net management fees and net total expenses of each Fund (expressed as a percentage of average net assets) in absolute terms and also in comparison to the fee and expense levels of a comparable universe of funds (the "Peer Universe" ) selected by an independent third-party fund data provider. The Independent Board Members also reviewed the methodology regarding the construction of the applicable Peer Universe.
In their evaluation of the management fee schedule, the Independent Board Members considered the fund-level and complex-wide breakpoint schedules, as described in further detail below. In this regard, the Board considered that management recently reviewed the breakpoint schedules for the closed-end funds which resulted in reduced breakpoints and/or new breakpoints at certain asset thresholds for numerous closed-end funds, including the Funds.

164 NUVEEN

In reviewing the comparative fee and expense information, the Independent Board Members recognized that various factors such as the limited size and particular composition of the Peer Universe (including the inclusion of other Nuveen funds in the peer set); expense anomalies; changes in the funds comprising the Peer Universe from year to year; levels of reimbursement or fee waivers; the timing of information used; the differences in the type and use of leverage; and differences in services provided can impact the usefulness of the comparative data in helping to assess the appropriateness of a fund's fees and expenses. In addition, in reviewing a fund's fees and expenses compared to the fees and expenses of its peers (excluding leverage costs and leveraged assets), the Board generally considered a fund's expenses and fees to be higher if they were over 10 basis points higher, slightly higher if they were 6 to 10 basis points higher, in line if they were within approximately 5 basis points higher than the peer average and below if they were below the peer average of the Peer Universe. The Board reviewed the net expense ratio in recognition that the net expense ratio generally best represented the net experience of the shareholders of a fund as it directly reflected the costs of investing in the respective fund. The Board noted that the majority of the Nuveen funds had a net expense ratio near or below the average of the respective peers. For funds with a net expense ratio of 6 basis points or higher than their respective peer average, the Independent Board Members reviewed the reasons for the outlier status and were satisfied with the explanation for the difference or with any steps taken to address the difference.

The Independent Board Members noted that the Credit Income Fund and the High Income Fund each had a net management fee slightly higher than its peer average but a net expense ratio in line with its peer average, and the AMT-Free Fund had a net expense ratio slightly higher than its peer average (generally due to one-time merger expenses as a result of acquiring other funds) but a net management fee in line with its peer average.

Based on their review of the fee and expense information provided, the Independent Board Members determined that each Fund's management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.

  1. Comparisons with the Fees of Other Clients

The Board also reviewed information regarding the fee rates for other types of clients advised or sub-advised by the respective Fund Adviser. For the Adviser and/or the Sub-Adviser, such other clients may include municipal separately managed accounts and passively managed exchange traded funds (ETFs).

The Board recognized that each Fund had an affiliated sub-adviser. With respect to affiliated sub-advisers, the Board reviewed, among other things, the range of advisory fee rates and average fee rate assessed for the different types of clients. The Board reviewed information regarding the different types of services provided to the Funds compared to that provided to these other clients which typically did not require the same breadth of day-to-day services required for registered funds. The Board further considered information regarding the differences in, among other things, investment policies, investor profiles, and account sizes between the Nuveen funds and the other types of clients. In addition, the Independent Board Members also recognized that the management fee rates of the foreign funds advised by the Adviser may also vary due to, among other things, differences in the client base, governing bodies, operational complexities and services covered by the management fee. The Independent Board Members recognized that the foregoing variations resulted in different economics among the product structures and culminated in varying management fees among the types of clients and funds.

The Board also was aware that, since the Funds had a sub-adviser, each Fund's management fee reflected two components, the fee retained by the Adviser for its services and the fee the Adviser paid to the Sub-Adviser. The Board noted that many of the administrative services provided to support the Funds by the Adviser may not be required to the same extent or at all for the institutional clients or other clients. In general, the Board noted that higher fee levels reflected higher levels of service provided by the Fund Adviser, increased investment management complexity, greater product management requirements and higher levels of business risk or some combination of the foregoing. Given the inherent differences in the various products, particularly the extensive services provided to the Funds, the Independent Board Members concluded such facts justify the different levels of fees.

  1. Profitability of Fund Advisers

In conjunction with their review of fees, the Independent Board Members also considered the profitability of Nuveen for its advisory activities on an absolute basis and in comparison to other investment advisers. The Independent Board Members reviewed, among other things, Nuveen's adjusted operating margins, the gross and net revenue margins (pre-tax and after-tax) for advisory activities for the Nuveen funds, and the revenues, expenses, and net income (pre-tax and after-tax) of Nuveen for each of the last two calendar years. The Independent Board Members reviewed an analysis of the key drivers behind the changes in revenues and expenses that impacted profitability in 2015. The Independent Board Members also noted that the sub-advisory fees for the Funds are paid by the Adviser, however, the Board recognized that the Sub-Adviser is affiliated with Nuveen. In their review, the Independent Board Members recognized that profitability data is rather subjective as various allocation methodologies may be reasonable to employ but yet yield different results. The Board also reviewed the results of certain alternative methodologies. The Board considered the allocation methodology employed to prepare the profitability data as well as a summary of the refinements to the methodology that had been adopted over the years which may limit some of the comparability of Nuveen's revenue margins over time. Two Independent Board Members also served as point persons for the Board throughout the year to review and discuss the methodology employed to develop the profitability analysis and any proposed changes thereto and to keep the Board apprised of such changes during the year. In reviewing the profitability data, the Independent Board Members noted that Nuveen's operating margin as well as its margins for its advisory activities to the Nuveen funds for 2015 were consistent with such margins for 2014.

The Board also considered Nuveen's adjusted operating margins compared to that of other comparable investment advisers (based on asset size and composition) with publicly available data. The Independent Board Members recognized, however, the limitations of the comparative data as the other advisers may have a different business mix, employ different allocation methodologies, have different capital structure and costs, may not be representative of the industry or other factors that limit the comparability of the profitability information. Nevertheless, the Independent Board Members noted that Nuveen's adjusted operating margins appeared comparable to the adjusted margins of the peers.

Further, as the Adviser is a wholly-owned subsidiary of Nuveen which in turn is an operating division of TIAA Global Asset Management, the investment management arm of Teachers Insurance and Annuity Association of America ( "TIAA-CREF" ), the Board reviewed a balance sheet for TIAA-CREF reflecting its assets, liabilities and capital and contingency reserves for the last two calendar years to have a better understanding of the financial stability and strength of the TIAA-CREF complex, together with Nuveen.

Based on the information provided, the Independent Board Members noted that the Adviser appeared to be sufficiently profitable to operate as a viable investment management firm and to honor its obligations as a sponsor of the Nuveen funds.

With respect to the Sub-Adviser, the Independent Board Members also considered the profitability of the Sub-Adviser from its relationship with the Nuveen funds. The Independent Board Members reviewed the Sub-Adviser's revenues, expenses and revenue margins (pre- and post-tax) for its advisory activities for the calendar year ended December 31, 2015. The Independent Board Members also reviewed profitability analysis reflecting the revenues, expenses and revenue margin (pre- and post-tax) by asset type for the Sub-Adviser for the calendar year ending December 31, 2015.

In evaluating the reasonableness of the compensation, the Independent Board Members also considered other amounts paid to a Fund Adviser by the Funds as well as indirect benefits (such as soft dollar arrangements), if any, the Fund Adviser and its affiliates received or were expected to receive that were directly attributable to the management of a Fund. See Section E below for additional information on indirect benefits a Fund Adviser may receive as a result of its relationship with the Funds.

Based on their review, the Independent Board Members determined that the Adviser's and the Sub-Adviser's levels of profitability were reasonable in light of the respective services provided.

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

The Independent Board Members recognized that as the assets of a particular fund or the Nuveen complex in the aggregate increase over time, economies of scale may be realized with respect to the management of the funds, and the Independent Board Members considered the extent to which these economies are shared with the funds and their shareholders. Although the Independent Board Members recognized that economies of scale are difficult to measure with precision, the Board noted that there were several acceptable means to share economies of scale, including through breakpoints in the management fee schedule reducing the fee rates as asset levels grow, fee waiver and expense limitation agreements and the Adviser's investment in its business which can enhance the services provided to the funds. With respect to breakpoints, the Independent Board Members noted that, subject to certain exceptions, the funds in the Nuveen complex pay a management fee to the Adviser which is generally comprised of a fund-level component and complex-level component. The fund-level fee component declines as the assets of the particular fund grow and the complex-level fee component declines when eligible assets of all the funds in the Nuveen complex combined grow. With respect to closed-end funds, the Independent Board Members noted that, although such funds may from time-to-time make additional share offerings, the growth of their assets would occur primarily through the appreciation of such funds' investment portfolios. The complex-wide fee arrangement was designed to capture economies of scale achieved when total fund complex assets increase, even if the assets of a particular fund are unchanged or decrease. The approach reflected the notion that some of Nuveen's costs were attributable to services provided to all its funds in the complex, and therefore all funds should benefit if these costs were spread over a larger asset base.

The Independent Board Members reviewed the breakpoint and complex-wide schedules and the material savings achieved from fund-level breakpoints and complex-wide fee reductions for the 2015 calendar year.

In addition, the Independent Board Members recognized the Adviser's ongoing investment in its business to expand or enhance the services provided to the Nuveen funds. The Independent Board Members noted, among other things, the additions to groups who play a key role in supporting the funds including in closed-end funds/structured products, fund administration, operations, fund governance, investment services, compliance, product management, and technology. The Independent Board Members also recognized the investments in systems necessary to manage the funds including in areas of risk oversight, information technology and compliance.

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

E. Indirect Benefits

The Independent Board Members received and considered information regarding other additional benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the Funds, including compensation paid to affiliates and research received in connection with brokerage transactions (i.e., soft dollar arrangements). In this regard, the Independent Board Members noted any revenues received by affiliates of the Adviser for serving as co manager in initial public offerings of new closed-end funds and as underwriter on shelf offerings for certain existing funds.

In addition to the above, the Independent Board Members considered that the Funds' portfolio transactions are allocated by the Sub-Adviser and the Sub-Adviser may benefit from research received through soft-dollar arrangements. The Board noted, however, that with respect to transactions in fixed income securities, such securities generally trade on a principal basis and do not generate soft dollar credits. Although the Board recognized the Sub-Adviser may benefit from a soft dollar arrangement if it does not have to pay for this research out of its own assets, the Board also recognized that any such research may benefit the Funds to the extent it enhances the ability of the Sub-Adviser to manage the Funds.

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

F. Other Considerations

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

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant’s Board of Directors or Trustees (“Board”) determined that the registrant has at least one “audit committee financial expert” (as defined in Item 3 of Form N-CSR) serving on its Audit Committee. The registrant’s audit committee financial experts are Carole E. Stone and Jack B. Evans, who are “independent” for purposes of Item 3 of Form N-CSR.

Prior to serving as Director, Ms. Stone worked as a budget analyst/examiner with increasing levels of responsibility over a 30 year period, including approximately five years as Deputy Budget Director. Ms. Stone has also served as Chair of the New York State Racing Association Oversight Board, as Chair of the Public Authorities Control Board, as a Commissioner on the New York State Commission on Public Authority Reform and as a member of the Boards of Directors of several New York State public authorities. These positions have involved overseeing operations and finances of certain entities and assessing the adequacy of project/entity financing and financial reporting. Currently, Ms. Stone is on the Board of Directors of CBOE Holdings, Inc., of the Chicago Board Options Exchange, and of C2 Options Exchange. Ms. Stone’s position on the boards of these entities and as a member of both CBOE Holdings’ Audit Committee and its Finance Committee has involved, among other things, the oversight of audits, audit plans and preparation of financial statements.

As part of his role as President and Chief Operating Officer, Mr. Evans actively supervised the Chief Financial Officer (the “CFO”) and actively supervised the CFO’s preparation of financial statements and other filings with various regulatory authorities.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Nuveen AMT-Free Municipal Credit Income Fund 5

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

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

1 "Audit Fees" are the aggregate fees billed for professional services for the audit of the Fund's annual financial statements and services provided in
connection with statutory and regulatory filings or engagements.
2 "Audit Related Fees" are the aggregate fees billed for assurance and related services reasonably related to the performance of the audit or review of
financial statements that are not reported under "Audit Fees". These fees include offerings related to the Fund's common shares and leverage.
3 "Tax Fees" are the aggregate fees billed for professional services for tax advice, tax compliance, and tax planning. These fees include: all global
withholding tax services; excise and state tax reviews; capital gain, tax equalization and taxable basis calculation performed by the principal accountant.

SERVICES THAT THE FUND’S AUDITOR BILLED TO THE ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

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

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

NON-AUDIT SERVICES

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

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

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

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

The Adviser is responsible for the on-going monitoring of the Fund’s investment portfolio, managing the Fund’s business affairs and providing certain clerical, bookkeeping and administrative services. The Adviser has engaged Nuveen Asset Management, LLC (“Sub-Adviser”) as Sub-Adviser to provide discretionary investment advisory services. As part of these services, the Adviser has delegated to the Sub-Adviser the full responsibility for proxy voting on securities held in the registrant’s portfolio and related duties in accordance with the Sub-Adviser’s policies and procedures. The Adviser periodically monitors the Sub-Adviser’s voting to ensure that it is carrying out its duties. The Sub-Adviser’s proxy voting policies and procedures are attached to this filing as an exhibit and incorporated herein by reference.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

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

Item 8(a)(1). PORTFOLIO MANAGER BIOGRAPHY

Paul Brennan, CFA, CPA, manages several Nuveen municipal national and state mutual funds and closed-end bond funds. Paul began his career in the investment business in 1991, as a municipal credit analyst for Flagship Financial, before becoming a portfolio manager in 1994. He joined Nuveen Investments in 1997, when Nuveen acquired Flagship Financial that year. He earned his B.S. in Accountancy and Finance from Wright State University. He is a CPA, has earned the Chartered Financial Analyst (CFA) designation, and currently sits on the Nuveen Asset Management Investment Management Committee.

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

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

Portfolio Manager Type of Account Managed Number of Accounts Assets*
Paul Brennan Registered Investment Company 10 $13.95 billion
Other Pooled Investment Vehicles 1 $37.8 million
Other Accounts 2 $54.4million
  • Assets are as of October 31, 2016. None of the assets in these accounts are subject to an advisory fee based on performance.

POTENTIAL MATERIAL CONFLICTS OF INTEREST

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

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

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

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

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

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

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

Portfolio manager compensation consists primarily of base pay, an annual cash bonus and long term incentive payments.

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

Annual cash bonus. The Fund’s portfolio managers are eligible for an annual cash bonus based on investment performance, qualitative evaluation and financial performance of Nuveen Asset Management.

A portion of each portfolio manager’s annual cash bonus is based on the Fund’s investment performance, generally measured over the past one- and three or five-year periods unless the portfolio manager’s tenure is shorter. Investment performance for the Fund generally is determined by evaluating the Fund’s performance relative to its benchmark(s) and/or Lipper industry peer group.

A portion of the cash bonus is based on a qualitative evaluation made by each portfolio manager’s supervisor taking into consideration a number of factors, including the portfolio manager’s team collaboration, expense management, support of personnel responsible for asset growth, and his or her compliance with Nuveen Asset Management‘s policies and procedures.

The final factor influencing a portfolio manager’s cash bonus is the financial performance of Nuveen Asset Management based on its operating earnings.

Long-term incentive compensation. Certain key employees of Nuveen Investments and its affiliates, including certain portfolio managers, participate in a Long-Term Performance Plan designed to provide compensation opportunities that links a portion of each participant’s compensation to Nuveen Investments’ financial and operational performance. In addition, certain key employees of Nuveen Asset Management, including certain portfolio managers, have received profits interests in Nuveen Asset Management which entitle their holders to participate in the firm’s growth over time.

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