to Shareholders

Dear Shareholders,

The past year saw a striking shift in the markets’ tone. The start of 2016 was beset by China’s economic woes, growing recession fears in the U.S. and oil prices sinking to lows not seen in more than a decade. World stock markets plunged, while bonds and other safe-haven assets rallied. But, by the end of the year, optimism had taken root. Economic outlooks were more upbeat, commodity prices stabilized, equity markets rebounded and bonds retreated. Despite the initial shocks of the Brexit referendum in the U.K. and Donald Trump’s win in the U.S. presidential election, and the uncertainties posed by the implications of these votes, sentiment continued to swing toward the positive as 2016 ended.

In between the year’s turbulent start and exuberant end, markets were soothed by improving economic data out of China, as the government’s stimulus measures appeared to be working, and a recovery in the energy and commodity-related sectors. The U.S. Federal Reserve backed off its more aggressive projections from the beginning of the year, only raising the fed funds rate once during the year, in December. The central banks in Europe and Japan maintained their accommodative stances. Global economic growth remained lackluster overall, as the pace of U.S. growth remained consistently mediocre. China appeared to moderate its slowdown and low growth in Europe and Japan persisted.

Will 2017 be the year of accelerating global growth and rising inflation that the markets are expecting? President Trump’s business-friendly, pro-growth agenda has been well received by the markets, but the policy details and the timeline have yet to take shape. Furthermore, there could be potential downside risks if “Trumponomics” were to trigger a steeper rise in inflation or a trade war. Outside the U.S., political dynamics in Europe are also in flux this year, with Brexit negotiations ongoing and elections in Germany, France and the Netherlands, and possibly a snap election in Italy.

Given the slate of policy unknowns and the range of possible outcomes, we believe volatility will remain a fixture this year. 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,

Nuveen S&P 500 Buy-Write Income Fund (BXMX)

Nuveen Dow 30^SM Dynamic Overwrite Fund (DIAX)

Nuveen S&P 500 Dynamic Overwrite Fund (SPXX)

Nuveen Nasdaq 100 Dynamic Overwrite Fund (QQQX)

The Nuveen S&P 500 Buy-Write Income Fund (BXMX) features portfolio management by Gateway Investment Advisers, LLC (Gateway). Kenneth H. Toft, CFA, and Michael T. Buckius, CFA, are portfolio managers. Effective February 29, 2016, Daniel M. Ashcraft, CFA was added as a portfolio manager for BXMX. Nuveen Dow 30^SM Dynamic Overwrite Fund (DIAX), Nuveen S&P 500 Dynamic Overwrite Fund (SPXX) and Nuveen Nasdaq 100 Dynamic Overwrite Fund (QQQX) feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen, LLC. Keith B. Hembre, CFA, and David Friar serve as portfolio managers for the Funds.

On December 21, 2016, the Board of Trustees approved a primary benchmark change for the Nuveen S&P 500 Buy-Write Income Fund (BXMX). Effective December 31, 2016, the CBOE S&P 500 BuyWrite Index (BXM) is the new primary benchmark as it more closely aligns with BXMX’s mandate. The CBOE S&P 500 BuyWrite Index (BXM) previously served as the secondary benchmark for the Fund, but this change moves it to the primary benchmark position (replacing the S&P 500^® Index). The Fund no longer has a secondary benchmark.

Here the portfolio managers discuss management strategies and the performance of the Funds for the twelve-month reporting period ended December 31, 2016.

What factors affected the U.S. economy and domestic and global markets during the twelve-month reporting period ended December 31, 2016?

The restrained pace of growth that has defined the U.S. economic recovery since 2009 continued in the twelve-month reporting period. In the four calendar quarters of 2016, growth 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. Weakness was more pronounced in the first half of the reporting period, as GDP growth averaged below 1.5% in the first two quarters. Although a short-term jump in exports contributed to a more robust gain of 3.5% in the third quarter, the drop in exports that followed widened the trade deficit, which dampened economic activity to a 1.9% annualized rate in the last three months of 2016, as reported by the “advance” 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 fell to 4.7% in December 2016 from 5.0% in December 2015 and job gains averaged slightly above 200,000 per month for the past twelve months. Consumer spending surged in the second quarter of 2016, then decelerated somewhat in the second half of the reporting period. Moreover, as the cost of gasoline and rents climbed over

Portfolio Managers’ Comments (continued)

2016, inflation ticked higher. The Consumer Price Index (CPI) rose 2.1% over the twelve-month reporting period ended December 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 2.2% during the same period, slightly above the Federal Reserve’s (Fed) 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 5.6% annual gain in November 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 4.5% and 5.3%, respectively.

Business spending weakened in the first half of 2016 but modestly improved over the remainder of the year. Early in the reporting period, the energy sector’s slump, financial market turbulence and a murky outlook on U.S. and global growth weighed on business sentiment and dampened spending. However, business confidence improved in the second half of the year, as oil prices stabilized, recession fears diminished and the election of Donald Trump stoked expectations for new pro-growth fiscal policy.

Given the economy’s consistent expansion and the uptick in the inflation rate, the Fed raised one of its main interest rates in December for the second time in a year, to a range of 0.50% to 0.75%. Additionally at its December 2016 meeting, the Fed revised its forecast from two to three increases in 2017, signaling greater confidence in the economy and rising inflation expectations.

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 in June 2016 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 Trump’s unexpected win 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 through the end of the reporting period.

The reporting period began with the S&P 500^® Index losing 10.27% through February 11^th, coupled with a steady decline in the yield on the 10-year U.S. Treasury Note, despite the Fed preparing investors for multiple rate hikes in 2016. Though equities had recovered to positive territory by the end of the first quarter, falling interest rates contributed to the bond market’s surprising outperformance of the stock market over the first half of the reporting period. Equity market conditions were calm in the second half of the reporting period despite the United Kingdom (UK) voting to leave the European Union and Donald Trump winning the U.S. presidential election. Neither outcome was expected and both were forecast to have a negative impact on capital markets in the unlikely event they came to pass. The S&P 500^® Index did decline 5.34% in the two days after the Brexit vote, but quickly recovered and advanced until mid-August 2016. The S&P 500^® Index declined 4.38% from August 15^th through November 4^th as both the Trump and Clinton campaigns struggled with negative developments. However, the equity market advanced steadily after the election as anticipation of pro-growth economic policies from the incoming Trump administration, plus mostly positive quarterly earnings and economic reports, helped propel the market. Interest rates rose in the second half of the reporting period, accelerating after the election. The Dow Jones Industrial Average and Nasdaq 100 Index also ended the reporting period up 16.50% and 7.27% respectively.

Implied volatility, as measured by the Chicago Board Options Exchange (CBOE) Volatility Index (the VIX), averaged 15.83 for the reporting period, based on the daily closing values of the VIX. This is well below its long-term average of 19.71 and a somewhat counter-intuitive outcome for an election year that included a great deal of uncertainty and multiple unexpected events. However, below-average volatility is not uncommon in election years and the pattern of volatility in 2016 was similar to typical election years in that the highest volatility readings came early in the year, troughed in the third quarter and rose in October and November.

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

BXMX

BXMX seeks attractive total return with less volatility than the S&P 500^® Index. During the twelve-month reporting period ended December 31, 2016, BXMX invested in an equity portfolio which sought to track the price movements of the S&P 500^® Index and wrote (sold) listed index call options on approximately 100% of the notional value of its stock portfolio. The cash premium generated by the index call options is intended to supplement the dividend yield on the underlying stock portfolio to support the Fund’s distribution policy and to provide the potential for growth in value during rising markets and/or risk mitigation in the event of a market decline.

The writing of index call options on a broad equity index, while investing in a portfolio of equities, has the potential to enhance BXMX’s risk-adjusted returns while exposing the Fund to less risk than unhedged equity investments. The portion of the Fund subject to the overwrite potentially forgoes some of its upside equity return in exchange for the cash flow premium received for the written index call options. In addition, market declines are typically buffered by the amount of the cash flow premium BXMX receives. In flat or declining markets, BXMX’s call option premium can potentially enhance total return relative to the S&P 500^® Index. In rising markets, the options can reduce the Fund’s total return relative to the S&P 500^® Index.

DIAX

DIAX seeks attractive total return with less volatility than the Dow Jones Industrial Average (DJIA). NAM varies the level of call option overwrite within a range of approximately 35% to 75%, with a long-run target of 55% overwrite. NAM uses its proprietary view of the market’s return and volatility profile to dynamically adjust the overwrite percentage and other factors. Generally, if NAM expects the equity market to appreciate, the overwrite percentage will be reduced to offer more potential upside capture. Likewise, if NAM expects equity markets to be flat or to decline, the overwrite percentage may be increased, thus managing the Fund to potentially receive additional cash flow from higher sales of call options. This dynamic option overwrite approach offers potential for greater equity market upside capture than the full overwrite approach, while still offering a measure of downside protection. The Fund currently expects to carry out its principal investment strategy by emphasizing options on broad-based indexes, individual stocks in the DJIA, and options on custom baskets of stocks in addition to ETFs. The Fund also has the opportunity to utilize call spread strategies and sell put options on a portion of the underlying equity portfolio.

SPXX

SPXX seeks attractive total return with less volatility than the S&P 500^® Index. NAM varies the level of option overwrite within a range of approximately 35% to 75% overwrite, with a long-run target of 55% overwrite. NAM uses its proprietary view of the market’s return and volatility profile to dynamically adjust the overwrite percentage and other factors. Generally, if NAM expects the equity market to appreciate, the overwrite percentage will be reduced to offer more potential upside capture. Likewise, if NAM expects equity markets to be flat or to decline, the overwrite percentage may be increased, thus managing the Fund to potentially receive additional cash flow from higher sales of call options.

approach, while still offering a measure of downside protection. The Fund currently expects to emphasize index call options on the S&P 500^® Index and can also employ an expanded range of options including index options on other broad-based indexes and options on custom baskets of stocks in addition to single name options. The Fund also has the opportunity to utilize call spread strategies and sell put options on a portion of the underlying equity portfolio.

QQQX

QQQX seeks attractive total return with less volatility than the NASDAQ-100 Index. NAM varies the level of call option overwrite within a range of approximately 35% to 75% overwrite, with a long-run target of 55% overwrite. NAM uses its proprietary view of the market’s return and volatility profile to dynamically adjust the overwrite percentage and other factors. Generally, if NAM expects the equity market to appreciate, the overwrite percentage will be reduced to offer more potential upside capture. Likewise, if NAM expects equity markets to be flat or to decline, the overwrite percentage may be increased, thus managing the Fund to potentially receive additional cash flow from higher sales of call options. This dynamic option overwrite approach offers potential for greater equity market upside capture than the full overwrite approach, while still offering a measure of downside protection. The Fund, in carrying out its principal options strategy, expects to primarily write index call options on the NASDAQ-100 Index and other broad-based indexes and can also write call options on a variety of other equity market indexes and options on custom baskets of stocks in addition to single name options. The Fund also has the opportunity to utilize call spread strategies and sell put options on a portion of the underlying equity portfolio.

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

The tables in the Performance Overview and Holding Summaries section of this report provide total return for the one-year, five-year, ten-year and/or since inception periods ended December 31, 2016. Each Fund’s total returns at net asset value (NAV) are compared with the performance of its corresponding market index and, as available, a secondary custom blended benchmark.

For the twelve-month reporting period ended December 31, 2016 BXMX’s shares at NAV outperformed its index, which is now the CBOE S&P 500 BuyWrite Index (BXM). BXMX underperformed its previous primary index, the S&P 500^® Index. DIAX underperformed the Dow Jones Industrial Average, but outperformed its secondary index, which is a blend of 55% CBOE DJIA BuyWrite Index (BXD) and 45% Dow Jones Industrial Average. SPXX underperformed the S&P 500^® Index and its secondary index, which is a blend of 55% the CBOE S&P 500 BuyWrite Index (BXM) and 45% the S&P 500^® Index. QQQX underperformed the NASDAQ 100 Index and its secondary index, which is a blend of 55% CBOE Nasdaq 100 BuyWrite Index (BXN) and 45% NASDAQ 100 Index.

BXMX

During the reporting period ended December 31, 2016, BXMX invested in an equity portfolio which sought to track the total return of the S&P 500^® Index and wrote (sold) listed index call options on approximately 100% of the notional value of its stock portfolio. The premium generated by the index call options is intended to supplement the dividend yield on the underlying stock portfolio to support the Fund’s distribution policy and to provide risk mitigation in the event of a market decline.

Though collecting premiums from writing index call options generally allows BXMX to generate a positive return when the S&P 500^® Index advances, call option positions that expire or are closed out when the S&P 500^® Index is well above the option’s strike price may generate realized losses. The relatively sharp equity market advances of March and July 2016 and during the weeks following the November 2016 U.S. Presidential election drove losses in written call option positions. Gains on written call option positions were the primary driver of downside protection during the market decline at the beginning of the reporting period. Gains from call options also contributed positively to BXMX’s return in the second quarter, when the market advance was relatively steady.


	8			NUVEEN

BXMX outperformed its new primary benchmark, the BXM, for the reporting period primarily due to smaller losses from written call options than the BXM in the second half of the reporting period. Frequent adjustments to BXMX’s actively managed portfolio of written index call options as the market advanced resulted in smaller losses than the BXM’s individual index call options that are written monthly and held to expiration. BXMX posted a higher return from its equity portfolio relative to the S&P 500^® Index in the fourth quarter which also attributed to its outperformance over the BXM benchmark.

Consistent with its investment objective, the measured risk of the Fund was lower than that of the U.S. equity market as its standard deviation for 2016 was 8.85% versus 13.30% for the S&P 500^® Index. BXMX’s risk was similar to 8.65% annualized standard deviation of the BXM.

DIAX

DIAX seeks to dampen the beta (a measure of price volatility) of the overall portfolio by selling call options on a portion of the Fund’s underlying equity portfolio. This overwrite strategy provides incremental cash flow to the Fund and allows the portion of the Fund’s assets that are not overwritten to participate in any equity market rally. Those portions of the Fund that are overwritten have capped upside potential. The downside is buffered by the amount of cash flow premium received. Therefore, in flat or declining markets, the option premiums can enhance total returns relative to the Index. In rising markets, however, the options can hinder the Fund’s total return relative to the Index.

During the first half of the reporting period, the market’s implied volatility as measured by the CBOE Volatility Index (the “VIX”) fluctuated, especially during the first quarter of 2016 and the days leading up the U.K. referendum. Implied volatility is a key factor in determining options because it seeks to show how volatile the market might be in the future which can impact the options we use. The higher the volatility, the more likely it is that the price will hit or exceed a call option’s strike price. Consequently, the Fund will receive more premium selling an option on a highly volatile security. We must decide if the additional cash flow is worth the increased risk that the option will be exercised. Earlier in the reporting period, when volatility was higher, the Fund captured more income because the premiums from the options sold had increased in value. Although we reduced the Fund’s option overwrite levels to near 40% as the market rebounded, the Fund was not able to capture the full amount of the upside as the Index rallied. The Fund did outperform its secondary benchmark, which is a blend of 55% CBOE DJIA BuyWrite Index (BXD) and 45% Dow Jones Industrial Average. Unlike the BXD, which has a fixed overlay strategy, we were able to increase the Fund’s overwrite percentage to take advantage of the option premiums and then quickly reduce the option overlay amount to benefit from the equity market rally.

Given the low levels of implied and realized volatility during the second half of the reporting period, trading was considerably light. We kept our option strategy closely tied to the secondary benchmark, as the Fund’s performance reflects. Our average overwrite levels ranged from 73% to 37%, but on average was slightly elevated at 67% during the reporting period. These higher overwrite levels mainly occurred during the first half of the reporting period.

As volatility declined, we took advantage of several of the Fund’s strategies as they became more attractive during periods of lower volatility. We continued to sell call and put options on the VIX during the reporting period. Although, these had a negligible impact on performance, we continued to utilize the strategy. We also sold call options on the Russell 2000^® Index during the first quarter of 2016, which did contribute to performance. However, when we sold call options on the Russell 2000^® Index later in the reporting period, these options detracted. The Russell 2000^® Index was one of the best performing indices during the reporting period which made selling call options on the Index less attractive. During the second half of the reporting period, we also wrote call options on the S&P 500^® Index and NASDAQ 100 Index. During the first half of the reporting period, we did utilize custom baskets and single name option trades. However, during the second half of the reporting period, we did not feel the potential return justified the risk since premiums overall were generally lower.

Earlier in the reporting period, when volatility was higher, the Fund captured more income because the premiums from the options sold had increased in value. During this time, however, the BXN had a higher overwrite percentage than the Fund and this contributed to BXN’s outperformance.

Given the low levels of implied and realized volatility during the second half of the reporting period, trading was considerably light. We kept our option strategy closely tied to the secondary benchmark, as the Fund’s performance reflects.

The following information regarding each Fund’s distributions is current as of December 31, 2016, the Fund’s fiscal and tax year end, and may differ from previously issued distribution notifications. Each Fund’s distribution level may vary over time based on the Fund’s investment activities and portfolio investment value changes.

Each Fund has adopted a managed distribution program. The goal of a Fund’s managed distribution program is to provide shareholders relatively consistent and predictable cash flow by systematically converting its expected long-term return potential into regular distributions. As a result, regular distributions throughout the year will likely include a portion of expected long-term and/or short-term gains (both realized and unrealized), along with net investment income.

Important points to understand about Nuveen fund managed distributions are:

•

Each Fund seeks to establish a relatively stable common share distribution rate that roughly corresponds to the projected total return from its investment strategy over an extended period of time. However, you should not draw any conclusions about a Fund’s past or future investment performance from its current distribution rate.

•

Actual share returns will differ from projected long-term returns (and therefore a Fund’s distribution rate), at least over shorter time periods. Over a specific timeframe, the difference between actual returns and total distributions will be reflected in an increasing (returns exceed distributions) or a decreasing (distributions exceed returns) Fund net asset value.

•

Each period’s distributions are expected to be paid from some or all of the following sources:

•

net investment income consisting of regular interest and dividends,

•

net realized gains from portfolio investments, and

•

unrealized gains, or, in certain cases, a return of principal (non-taxable distributions).

•

A non-taxable distribution is a payment of a portion of a Fund’s capital. When a Fund’s returns exceed distributions, it may represent portfolio gains generated, but not realized as a taxable capital gain. In periods when the Fund’s returns fall short of distributions, it will represent a portion of your original principal unless the shortfall is offset during other time periods over the life of your investment (previous or subsequent) when the Fund’s total return exceeds distributions.

•

Because distribution source estimates are updated throughout the current fiscal year based on a Fund’s performance, these estimates may differ from both the tax information reported to you in each Fund’s 1099 statement, as well as the ultimate economic sources of distributions over the life of your investment.

The following table provides information regarding each Fund’s distributions and total return performance over various time periods. This information is intended to help you better understand whether each Fund’s returns for the specified time periods were sufficient to meet their distributions.

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 S&P 500 Buy-Write Income Fund (BXMX)

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. Common stock returns often have experienced significant volatility. The Fund may not participate in any appreciation of its equity portfolio as fully as it would if the Fund did not sell call options. In addition, the Fund will continue to bear the risk of declines in the value of the equity portfolio. Because index options are settled in cash, sellers of index call options, such as the Fund, cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. For these and other risks, including tax risk, please see the Fund’s web page at www.nuveen.com/BXMX.

(a)	Per share Net Investment Income (Loss) is calculated using the average daily shares method.

(b)

Total Return Based on NAV is the combination of changes in NAV, reinvested dividend income at NAV and reinvested capital gains distributions at NAV, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending NAV. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized.

Total Return Based on 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.

Shares of BXMX, DIAX and SPXX are traded on the NYSE while shares of QQQX are traded on the NASDAQ. BXMX, DIAX, SPXX and QQQX were organized as Massachusetts business trusts on July 23, 2004, May 20, 2014, November 11, 2004 and May 20, 2014, respectively.

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

Investment Adviser

The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub-advisory agreements with Gateway Investment Advisers, LLC (“Gateway”), under which Gateway manages BXMX’s investment portfolio and Nuveen Asset Management, LLC (“NAM”), a subsidiary of the Adviser, under which NAM manages the investment portfolios of DIAX, SPXX and QQQX.

Investment Objectives and Principal Investment Strategies

BXMX’s investment objective is to provide a high level of current income and gains. The Fund invests its managed assets in a diversified equity portfolio that seeks to substantially replicate price movements of the S&P 500^® Index (effective December 31, 2016 the S&P 500 Buy-Write Index (BXM)). The Fund also uses an index option strategy of writing (selling) index call options in seeking to moderate the volatility of returns relative to an all equity portfolio.

DIAX’s investment objective is to seek attractive total return with less volatility than the Dow Jones Industrial Average^SM (“DJIA”). The Fund pursues its investment strategy by emphasizing single name options on individual stocks in the DJIA, as well as a range of options including index options on the DJIA and other broad-based indexes and options on custom baskets of stocks in addition to exchange-traded funds (ETFs). The Fund uses a dynamic call option overwrite strategy within a range of approximately 35% to 75%, with a long-run target of 55% overwrite of the value of the Fund’s equity portfolio, in seeking to enhance the portfolio’s risk-adjusted returns.

SPXX’s investment objective is to seek attractive total returns with less volatility than the S&P 500^® Index. The Fund pursues its investment strategy by emphasizing index call options on the S&P 500^® Index, as well as a range of options including index options on other broad-based indexes and options on custom baskets of stocks in addition to exchange-traded funds (ETFs). The Fund uses a dynamic call option overwrite strategy within a range of approximately 35% to 75%, with a long-run target of 55% overwrite of the value of the Fund’s equity portfolio, in seeking to enhance the portfolio’s risk-adjusted returns.

QQQX’s investment objective is to seek attractive total return with less volatility than the NASDAQ 100^® Index. The Fund pursues its investment strategy by emphasizing index call options on the NASDQ-100^® Index, as well other broad-based indexes and options on a variety of other equity market indexes and options on custom baskets of stocks in addition to exchange-traded funds (ETFs) and single name options. The Fund uses a dynamic call option overwrite strategy within a range of approximately 35% to 75%, with a long-run target of 55% overwrite of the value of the Fund’s equity portfolio, in seeking to enhance the portfolio’s risk-adjusted returns. The Fund also has the opportunity to utilize call spread strategies and sell put options on a portion of the underlying equity portfolio.

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 accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and losses from 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 Funds’ did not have any outstanding when-issued/delayed delivery purchase commitments.

Investment Income

Dividend income is recorded on the ex-dividend date or, for foreign securities, when information is available. Interest income is recorded on an accrual basis.

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 Shareholders

Distributions to shareholders 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.

Each Fund makes quarterly cash distributions to shareholders of a stated dollar amount per share. Subject to approval and oversight by the Funds’ Board of Trustees (the “Board”), each Fund seeks to maintain a stable distribution level designed to deliver the long-term return potential of each Fund’s investment strategy through regular quarterly distributions (a “Managed Distribution Program”). Total distributions during a calendar year generally will be made from each Fund’s net investment income, net realized capital gains and net unrealized capital gains in the Fund’s portfolio, if any. The portion of distributions paid attributed to net unrealized gains, if any, is distributed from the Fund’s assets and is treated by shareholders as a nontaxable distribution (“return of capital”) for tax purposes. In the event that total distributions during a calendar year exceed a Fund’s total return on net asset value (“NAV”), the difference will reduce NAV per share. If a Fund’s total return on NAV exceeds total distributions during a calendar year, the excess will be reflected as an increase in NAV per share. The final determination of the source and character of all distributions paid by a Fund during the fiscal year is made after the end of the fiscal year and is reflected in the financial statements contained in the annual report as of December 31 each year.

Indemnifications

Under the Funds’ organizational documents, their officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and 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 master repurchase agreements, 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, a 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.


NUVEEN			57

Notes to Financial Statements (continued)

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 from operations during the current fiscal period. Actual results may differ from those estimates.

2. 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).

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 last quoted bid price and are generally classified as Level 2. Prices of certain American Depositary Receipts (“ADR”) held by the Funds that trade in the United States are valued based on the last traded price, official closing price, or the most recent bid price of the underlying non-U.S.-traded stock, adjusted as appropriate for the underlying-to-ADR conversion ratio and foreign exchange rate, and from time-to-time may also be adjusted further to take into account material events that may take place after the close of the local non-U.S. market but before the close of the NYSE, which may represent a transfer from a Level 1 to a Level 2 security.

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

Exchange-traded funds are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1.

Index options are valued at the 4:00 p.m. Eastern Time (ET) close price of the NYSE. The values of exchange-traded options are based on the mean of the closing bid and ask prices. Index and exchange-traded options are generally classified as Level 1. Options traded in the over-the-counter market are valued using an evaluated mean price and are generally classified as Level 2.

Repurchase agreements are valued at contract amount plus accrued interest, which approximates market value. These securities are generally classified as Level 2.

Investments initially valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from pricing services. As a result, the NAV of a Fund’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of securities traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the NYSE is closed and an investor is not able to purchase, redeem or exchange shares. If significant market events occur between the time of determination of the closing price of a foreign security on an exchange and the time that the Funds’ NAV is determined, or if under the Funds’ procedures, the closing price of a foreign security is not deemed to be reliable, the security would be valued at fair value as determined in accordance with procedures established in good faith by the Board. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs.

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


	58			NUVEEN

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:

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.


NUVEEN			59

Notes to Financial Statements (continued)

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.

3. Portfolio Securities and Investments in Derivatives

Portfolio Securities

Foreign Currency Transactions

To the extent that the Funds invest in securities and/or contracts that are denominated in a currency other than U.S. dollars, the Funds will be subject to currency risk, which is the risk that an increase in the U.S. dollar relative to the foreign currency will reduce returns or portfolio value. Generally, when the U.S. dollar rises in value against a foreign currency, the Funds’ investments denominated in that currency will lose value because their currency is worth fewer U.S. dollars; the opposite effect occurs if the U.S. dollar falls in relative value. Investments and other assets and liabilities denominated in foreign currencies are converted into U.S. dollars on a spot (i.e. cash) basis at the spot rate prevailing in the foreign currency exchange market at the time of valuation. Purchases and sales of investments and income denominated in foreign currencies are translated into U.S. dollars on the respective dates of such transactions.

The books and records of the Funds are maintained in U.S. dollars. Foreign currencies, assets and liabilities are translated into U.S. dollars at 4:00 p.m. Eastern Time. Investment transactions, income and expenses are translated on the respective dates of such transactions. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date of the transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Funds and the amounts actually received.

The realized gains and losses resulting from changes in foreign currency exchange rates and changes in foreign exchange rates associated with (i) foreign currency, (ii) investments, (iii) investments in derivatives and (iv) other assets and liabilities are recognized as a component of “Net realized gain (loss) from investments and foreign currency,” on the Statement of Operations, when applicable.

The unrealized gains and losses resulting from changes in foreign currency exchange rates and changes in foreign exchange rates associated with (i) investments and (ii) other assets and liabilities are recognized as a component of “Change in unrealized appreciation (depreciation) of investments and foreign currency,” on the Statement of Operations, when applicable. The unrealized gains and losses resulting from changes in foreign exchange rates associated with investments in derivatives are recognized as a component of the respective derivative’s related “Change in net unrealized appreciation (depreciation)” on the Statement of Operations, when applicable.

Repurchase Agreements

In connection with transactions in repurchase agreements, it is each Fund’s policy that its custodian take possession of the underlying collateral securities, the fair value of which exceeds the principal amount of the repurchase transaction, including accrued interest, at all times. If the counterparty defaults, and the fair value of the collateral declines, realization of the collateral may be delayed or limited.

The following table presents the repurchase agreements for the Funds that are subject to netting agreements as of the end of the reporting period, and the collateral delivered related to those repurchase agreements.


Fund	Counterparty	Short-Term Investments, at Value		Collateral Pledged (From) Counterparty*			Net Exposure
BXMX	Fixed Income Clearing Corporation	$	35,131,385	$	(35,131,385	)	$	—

*	As of the end of the reporting period, the value of the collateral pledged from the counterparty exceeded the value of the repurchase agreements. Refer to the Fund’s Portfolio of Investments for details on the repurchase agreements.


	60			NUVEEN

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

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 regulation 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.

Options Transactions

The purchase of options involves the risk of loss of all or a part of the cash paid for the options (the premium). The market risk associated with purchasing options is limited to the premium paid. The counterparty credit risk of purchasing options, however, needs to take into account the current value of the option, as this is the performance expected from the counterparty. When a Fund purchases an option, an amount equal to the premium paid (the premium plus commission) is recognized as a component of “Options purchased, at value” on the Statement of Asset and Liabilities. When a Fund writes an option, an amount equal to the net premium received (the premium less commission) is recognized as a component of “Options written, at value” on the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current value of the written option until the option is exercised or expires or the Fund enters into a closing purchase transaction. The changes in the value of options purchased and/or written during the fiscal period are recognized as a component of “Change in net unrealized appreciation (depreciation) of options purchased and/or written” on the Statement of Operations. When an option is exercised or expires or a Fund enters into a closing purchase transaction, the difference between the net premium received, and any amount paid at expiration or on executing a closing purchase transaction, including commission, is recognized as a component of “Net realized gain (loss) from options purchased and/or written” on the Statement of Operations. The Fund, as writer of an option, has no control over whether the underlying instrument may be sold (called) or purchased (put) and as a result bears the risk of an unfavorable change in the market value of the instrument underlying the written option. There is also the risk the Fund may not be able to enter into a closing transaction because of an illiquid market.

During the current fiscal period, BXMX sold call options on equity indices as part of its overall investment strategy with the notional amount of these options averaging 99% of the Fund’s assets.

During the current fiscal period, DIAX, SPXX and QQQX, each sold call options on equity indices as part of its overall investment strategy with the notional amounts of these options averaging 60% of each Fund’s assets. Each Fund also purchased a small amount of call options as part of its overwrite strategy and sold put options on up to 5% of its portfolio.

The average notional amount of outstanding options purchased and options written during the current fiscal period, was as follows:


				DIAX			SPXX			QQQX
Average notional amount of outstanding call options purchased*				$	12,886,000		$	5,518,000		$	16,164,000

	BXMX			DIAX			SPXX			QQQX
Average notional amount of outstanding call options written*	$	(1,344,551,100	)	$	(340,583,715	)	$	(141,565,200	)	$	(421,828,000	)

				DIAX			SPXX			QQQX
Average notional amount of outstanding put options written*				$	(5,868,000	)	$	(2,394,000	)	$	(7,308,000	)

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

Market and Counterparty Credit Risk

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

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.

6. Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment company taxable income to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. In any year when the Funds realize net capital gains, each Fund may choose to distribute all or a portion of its net capital gains to shareholders, or alternatively, to retain all or a portion of its net capital gains and pay federal corporate income taxes on such retained gains.

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 recording income, timing differences in recognizing certain gains and losses on investment transactions and the recognition of unrealized gain or loss for tax (mark-to-market) on options contracts. 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 December 31, 2016, the cost and unrealized appreciation (depreciation) of investments (excluding investments in derivatives), as determined on a federal income tax basis, were as follows:


	BXMX			DIAX			SPXX			QQQX
Cost of investments	$	868,867,983		$	361,322,674		$	151,008,996		$	341,859,018

Notes to Financial Statements (continued)



Permanent differences, primarily due to foreign currency transactions, nondeductible reorganization expenses, real estate investment trust adjustments, and tax basis earnings and profits adjustments, resulted in reclassifications among the Funds’ components of net assets as of December 31, 2016, the Funds’ tax year end, as follows:

7. Management Fees and Other Transactions with Affiliates

Management Fees

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. Gateway and NAM are compensated for their 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 the 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 schedule:


Average Daily Managed Assets*	BXMX			DIAX			SPXX			QQQX
For the first $500 million		0.7000	%		0.7000	%		0.6600	%		0.6900	%
For the next $500 million		0.6750			0.6750			0.6350			0.6650
For the next $500 million		0.6500			0.6500			0.6100			0.6400
For the next $500 million		0.6250			0.6250			0.5850			0.6150
For managed assets over $2 billion		0.6000			0.6000			0.5600			0.5900

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 each 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 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 and assets in excess of a determined amount (originally $2 billion) added to the Nuveen fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011. As of December 31, 2016, the complex-level fee rate for each Fund was 0.1625%.

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.

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

Your Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares.

By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested.

It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.

Easy and convenient

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

How shares are purchased

The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value on the last business day immediately prior to the purchase date, Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.

Flexible

You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change.

You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan.

The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

The following tables show the amount of fees that PricewaterhouseCoopers LLP, the Fund’s auditor, billed to the Fund during the Fund’s last two full fiscal years. For engagements with PricewaterhouseCoopers LLP the Audit Committee approved in advance all audit services and non-audit services that PricewaterhouseCoopers 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).

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 PricewaterhouseCoopers 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.

The Audit Committee is required to pre-approve non-audit services that PricewaterhouseCoopers 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 PricewaterhouseCoopers LLP about any non-audit services that PricewaterhouseCoopers 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 PricewaterhouseCoopers LLP’s independence.


Fiscal Year Ended	Total Non-Audit Fees Billed to Fund		Total Non-Audit Fees billed to Adviser and Affiliated Fund Service Providers (engagements related directly to the operations and financial reporting of the Fund)		Total Non-Audit Fees billed to Adviser and Affiliated Fund Service Providers (all other engagements)		Total

Other Accounts-overlay strategies – The portfolio manager is responsible for the management of overlay strategies employed by this account that use derivative instruments either to obtain, offset or substitute for certain portfolio exposures beyond those provided by the account’s underlying portfolios.

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 pre-tax 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 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.
