Chairman’s
Letter to Shareholders
 
 
Dear Shareholders,
 
After nine years of serving as lead director and independent chairman of the Nuveen Fund Board, my term of office is coming to an end. It has been a privilege to use this space to communicate with you on some of the broad economic trends in the U.S. and abroad and how they are impacting the investment environment in which your funds operate. In addition, I have enjoyed offering some perspective on how your Board views the various Nuveen investment teams as they apply their investment disciplines in that investment environment.
 
My term has coincided with a particularly challenging period for both mutual fund sponsors and investors. Since 2000 there have been three periods of unusually strong stock market growth and two major market declines. Recent years have been characterized by a search for yield in fixed income securities to compensate for an extended period of very low interest rates. Funds are investing more in foreign and emerging markets that require extensive research capabilities to overcome the more limited transparency and higher volatility in those markets. New fund concepts often incorporate derivative financial instruments that offer efficient ways to hedge investment risk or gain exposure to selected markets. Fund trading teams operate in many new domestic and international venues with quite different characteristics. Electronic trading and global communication networks mean that fund managers must be able to thrive in financial markets that react instantaneously to newsworthy events and are more interconnected than ever.
 
Nuveen has committed additional resources to respond to these changes in the fund industry environment. It has added IT and research resources to assemble and evaluate the increased flow of detailed information on economies, markets and individual companies. Based on its experience during the financial crisis of 2008-09, Nuveen has expanded its resources dedicated to valuing and trading portfolio securities with a particular focus on stressed financial market conditions. It has added systems and experienced risk management professionals to work with investment teams to better help evaluate whether their funds’ risk exposures are appropriate in view of the return targets. The investment teams have also reflected on recent experience to reaffirm or modify their investment disciplines. Finally, experienced professionals and IT resources have been added to address new regulatory requirements designed to better inform and protect investors. The Board has enthusiastically encouraged these initiatives.
 
The Nuveen Fund Board has always viewed itself as your representatives to assure that Nuveen brings together experienced people, proven technologies and effective processes designed to produce results that meet investor expectations. It is important to note that our activities are highlighted by the annual contract renewal process. Despite its somewhat formal language, I strongly encourage you to read the summary because it offers an insight into our oversight process. The report is included in the back of this or a subsequent shareholder report. The renewal process is very comprehensive and includes a number of evaluations and discussions between the Board and Nuveen during the year. The summary also describes what has been achieved across the Nuveen fund complex and at individual funds such as yours.
 
As I leave the chairmanship and resume my role as a member of the Board, please be assured that I and my fellow Board members will continue to hold your interests uppermost in our minds as we oversee the management of your funds and that we greatly appreciate your confidence in your Nuveen fund.
 
Very sincerely,
 
 
Robert P. Bremner
Chairman of the Board

Portfolio managers Chris Drahn, Tom Spalding, Daniel Close and John Miller discuss key investment strategies and the six-month performance of these national Funds. Chris assumed portfolio management responsibility for NQM in January 2011, Tom has managed NQS and NQU since 2003, Dan assumed portfolio management responsibility for NPF in January 2011 and John has managed NMZ since its inception in 2003 and has been involved in the management of NMD since its inception in 2007. He assumed full portfolio management responsibility for NMD in 2010.
 
APPROVED FUND REORGANIZATION
 
On December 13, 2012, the reorganization of NMD into NMZ was approved by each Fund’s Board of Trustees. The reorganization is intended to create a single larger national Fund, which would potentially offer shareholders the following benefits:
 
Lower Fund expense ratios (excluding the effects of leverage), as fixed costs are spread over a larger asset base;
   
Enhanced secondary market trading, as larger Funds potentially make it easier for investors to buy and sell Fund shares;
   
Lower per share trading costs through reduced bid/ask spreads due to a larger common share float; and
   
Increased Fund flexibility in managing the structure and cost of leverage over time.
 
The reorganization was approved by shareholders at a special meeting on June 21, 2013 (subsequent to the close of this reporting period), and is expected to be completed before the opening of business on July 15, 2013.
 
Upon the closing of the reorganization, NMD will transfer its assets to NMZ in exchange for common and preferred shares of NMZ, and the assumption by NMZ of the liabilities of NMD. NMD will then be liquidated, dissolved and terminated in accordance with its Declaration of Trust.

In addition, shareholders of NMD will become shareholders of NMZ. Holders of common shares will receive newly issued common shares of NMZ, the aggregate net asset value of which will be equal to the aggregate net asset value of the common shares of NMD held immediately prior to the reorganization (including for this purpose fractional NMZ shares to which shareholders would be entitled). Fractional shares will be sold on the open market and shareholders will receive cash in lieu of such fractional shares. Holders of NMD’s preferred shares will receive on a one-for-one basis newly issued preferred shares of NMZ, in exchange for preferred shares of NMO held immediately prior to the reorganization.
 
What key strategies were used to manage these Funds during the six-month reporting period ended April 30, 2013?
 
In an environment characterized by tight supply, strong demand and lower yields, we continued to take a bottom-up approach to discovering sectors that appeared undervalued as well as individual credits that had the potential to perform well over the long term. During this period, NQS, and NQU generally found value in broad based essential services bonds backed by taxes or other revenues. We also added health care bonds and took advantage of attractive valuation levels to purchase tobacco credits, which resulted in a slight increase in our allocations of these bonds. We also selectively purchased Puerto Rico bonds. In NPF, we focused on such areas as electric utility, tollway and tobacco. In NQM, we purchased bonds from a variety of sectors, including health care, tollway, sewer and pre-paid gas credits.
 
In NMZ and NMD, our purchases largely focused on areas such as corporate-backed municipal bonds, community development districts (CDDs), health care and university education. Some examples of our purchases during this period included bonds issued for University of Maryland student housing, in NMD; Vigo County Hospital District, Indiana, in NMD; Illinois Institute of Technology, Illinois in NMD; Palm Glades CDD Florida, in NMZ and Lake Forest College, Illinois, in NMZ. We also added corporate tax-exempt bonds issued by Alcoa, USG and Navistar in NMZ. Both Funds also purchased bonds issued by the Tolomato CDD, Florida and Plaza Metropolitan District #1, Colorado. We also added to our existing position in American Airlines, earlier in the reporting period.
 
In general during this reporting period, all of the Funds emphasized bonds with longer maturities. This enabled us to take advantage of more attractive yields at the longer end of the municipal yield curve and also provided some protection for the Funds’ duration and yield curve positioning. In terms of quality, NQM and NPF did purchase lower rated bonds when we found attractive opportunities, as we believed these bonds continued to offer relative value. NQS and NQU generally focused on higher quality bonds with the goal of positioning these two Funds slightly more defensively. NMZ and NMD’s duration remained relatively unchanged and had a neutral impact on the Funds’ performance.

Our opportunities to purchase bonds with longer maturities and lower credit quality were somewhat constrained during this period by the structure of bonds typically issued as part of refinancing deals, which tend to be characterized by shorter maturities and higher credit quality.
 
Cash for new purchases during this period was generated primarily by the proceeds from an increased number of bond calls resulting from the growth in refinancings. During this period, we worked to redeploy these proceeds as well as those from maturing bonds to keep the Funds as fully invested as possible. In NPF, we also sold our last exposure to Detroit general obligation (GO) bonds. Overall, selling was relatively limited because the bonds in our portfolios generally offered higher yields than those available in the current marketplace.
 
As of April 30, 2013, all six of these Funds continued to use inverse floating rate securities. We employ inverse floaters for a variety of reasons, including duration management, income enhancement and total return enhancement. As part of our duration management strategies, NMZ and NMD also made moderate use of interest rate swaps and forward interest rate swaps to reduce price volatility risk to movements in U.S. interest rates relative to the Funds’ benchmark. During this period, these swaps had a positive impact on performance. These swaps remained in place at period end.
 
How did the Funds perform during the six-month reporting period ended April 30, 2013?
 
The tables in each Fund’s Performance Overview and Holding Summaries section of this report provide total returns for the Funds for the six-month, one-year, five-year, ten-year and since inception periods ended April 30, 2013. Each Fund’s total returns are compared with the performance of a corresponding market index and Lipper classification average.
 
For the six-months ended April 30, 2013, the total returns on common share net asset value (NAV) for NQM, NQS, NQU and NPF exceeded the return for the S&P Municipal Bond Index. NQM, NQS and NQU outperformed the average return for the Lipper General & Insured Leveraged Municipal Debt Funds Classification Average and NPF performed in line with this Lipper average. For the same period, NMZ and NMD under-performed the return for the S&P Municipal Bond High Yield Index and exceeded the return for the Lipper High-Yield Municipal Debt Funds Classification Average.
 
Key management factors that influenced the Funds’ returns during this period included duration and yield curve positioning, credit exposure, in particular in NMZ and NMD and sector allocation. In addition, the use of regulatory leverage was an important positive factor affecting the Funds’ performance over this period. Leverage is discussed in more detail later in this report.

Municipal bonds with longer maturities generally outperformed those with shorter maturities during this period. Overall, credits at the longest end of the municipal yield curve posted the strongest returns, while bonds at the shortest end produced the weakest results. For this period, duration and yield curve positioning was a major positive contributor to the performance of these Funds, with the net impact varying according to each Fund’s individual weightings along the yield curve. All of the Funds benefited from their holdings of long duration bonds, many of which had zero percent coupons, which generally outperformed the market. This was especially true in NQS and NQU, which were overweight in zero coupon bonds. Duration and yield curve positioning had a neutral impact on NMZ and NMD’s performance.
 
Credit exposure was another important factor in the Funds’ performance during these six-months, as lower quality bonds generally outperformed higher quality bonds. This outperformance was due in part to the greater demand for lower rated bonds as investors looked for investment vehicles offering higher yields. As investors became more comfortable taking on additional investment risk, credit spreads, or the difference in yield spreads between U.S. Treasury securities and comparable investments such as municipal bonds, narrowed through a variety of rating categories. As a result of this spread compression, all of these Funds benefited from their holdings of lower rated credits. Both NMZ and NMD had heavy weightings in credits rated BBB or lower as well as non-rated bonds, which also generally performed well. For the period, NPF was underweight bonds rated AAA and overweight BBB bonds, which contributed to its performance. While NQU and NQS had slightly higher allocation to AAA and AA rated bonds, which slightly detracted from their performance.
 
During this period, revenue bonds as a whole outperformed the general municipal market. Holdings that generally made positive contributions to the Funds’ returns included health care (together with hospitals), transportation (especially toll roads), education and water and sewer bonds. All of these Funds had strong weightings in health care, which added to their performance, although NPF’s allocation to this sector was smaller than that of the other five Funds. Also detracting from NPF was its allocation to industrial development revenues bonds (IDRs), which underperformed for the reporting period.
 
Tobacco credits backed by the 1998 master tobacco settlement agreement also performed extremely well, helped in part by their longer effective durations. These bonds also benefited from market developments, including increased demand for higher yielding investments by investors who had become less risk averse. In addition, based on recent data showing that cigarette sales had fallen less steeply than anticipated, the 46 states participating in the agreement stand to receive increased payments from the tobacco companies. As of April 30, 2013, NQM, NPF and especially NQS and NQU were overweight in tobacco bonds, which benefited their performance as tobacco

credits rallied. Although NMZ and NMD were underexposed to the tobacco sector relative to the S&P Municipal Bond High Yield Index, their weightings were strong enough to make a positive contribution to performance.
 
Another positive factor for NQS and NQU was an overweighting in the “other utility” sector, as it proved helpful to own gas prepaid credits, a category of bond issuance that rallied during the period. These securities are used by municipalities to prepay natural gas costs and control energy spending.
 
In NMZ and NMD, the Funds emphasized bonds in the real estate sector, particularly community development districts (CDDs). During this period, these Funds were rewarded with strong performance from these holdings including Tolomato CDD, Florida in both Funds, Harmony CDD, Florida in NMZ and Elk Grove Tax Assessment District, California, in NMD, as they experienced growth in assessed property valuations and debt service coverage. Both Funds have exposures to American Airlines facilities in several locations. As the airline is working through its bankruptcy proceedings, the airline has come to a favorable agreement with its labor union, as well as its bondholders. As a result, these holdings performed well for the Funds. Also benefiting both Funds’ performance was West Penn Allegheny Hospital bonds. Highmark Inc., an insurance company, acquired the hospital during the period in a cash offer.
 
In contrast, pre-refunded bonds, which are often backed by U.S. Treasury securities, were the poorest performing market segment during this period. The underperformance of these bonds can be attributed primarily to their shorter effective maturities and higher credit quality. As of April 30, 2013, NPF held the heaviest weighting of pre-refunded bonds, which detracted from its performance during this period. As higher quality credits with shorter durations, pre-refunded bonds generally do not fit the profiles of longer term, higher yielding Funds such as NMZ and NMD, and these two Funds had negligible exposure to pre-refunded bonds. GO bonds and utilities (e.g., resource recovery, public power) credits also lagged the performance of the general municipal market for this period. These Funds tended to have relatively lighter exposures to GOs, which lessened the impact of these holdings.
 
Shareholders also should be aware of an issue involving some of the Funds’ holdings. In December 2012, Moody’s down-graded Puerto Rico GO bonds to Baa3 from Baa1 based on Puerto Rico’s ongoing economic problems, unfunded pension liabilities, elevated debt levels and structural budget gaps. Prior to this reporting period, bonds issued by the Puerto Rico Sales Tax Financing Corporation (COFINA) also were downgraded by Moody’s to Aa3 from Aa2 in July 2012. The downgrade of the COFINA bonds was due mainly to the performance of Puerto Rico’s economy and its impact on the projected growth of sales tax revenues, and not to any sector or structural issues. In

addition, the COFINA bonds were able to maintain a higher rating than the GOs because, unlike the revenue streams supporting some Puerto Rican issues, the sales taxes supporting the COFINA bonds cannot be diverted and used to support the commonwealth’s GO bonds. Shareholders of the Funds should note that all of these Funds have exposure to Puerto Rico bonds, the majority of which are the dedicated sales tax bonds issued by COFINA.
 
During this reporting period, we also added to our Puerto Rico holdings in NQS and NQF, based on the credit strength of these bonds. These holdings were generally purchased as part of our efforts to keep the Funds fully invested and to provide higher yields, added diversification, and triple exemption (i.e., exemption from federal, state, and local taxes). For the reporting period ended April 30, 2013, Puerto Rico paper generally underperformed the market as whole. Because most of our holdings were the COFINA bonds, the overall impact on performance was minimal, differing from Fund to Fund in line with the type and amount of its holdings. As we continue to emphasize Puerto Rico’s stronger credits, we view the COFINA bonds as potentially long-term holdings and note that the commonwealth recently introduced various sales tax initiatives aimed at improving future collections.

Fund Leverage
 
IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES ON PERFORMANCE
 
One important factor impacting the returns of all these Funds relative to the comparative indexes was the Funds’ use of leverage. The Funds use leverage because their managers believe that, over time, leveraging provides opportunities for additional income and total return for common shareholders. However, use of leverage also can expose common shareholders to additional volatility. For example, as the prices of securities held by a Fund decline, the negative impact of these valuation changes on common share net asset value and common shareholder total return is magnified by the use of leverage. Conversely, leverage may enhance common share returns during periods when the prices of securities held by a Fund generally are rising. Leverage made a positive contribution to the performance of these Funds over this reporting period.
 
As of April 30, 2013, the Funds’ percentages of effective and regulatory leverage are shown in the accompanying table.

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 sometimes referred to as “‘40 Act Leverage” and is subject to asset coverage limits set forth in the Investment Company Act of 1940.

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.
 
All of the Funds in this report seek to pay stable dividends at rates that reflect each Fund’s past results and projected future performance. During certain periods, each Fund may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it holds the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s NAV. Conversely, if a Fund has cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Fund’s NAV. Each Fund will, over time,
 
Nuveen Investments

pay all of its net investment income as dividends to shareholders. As of April 30, 2013, all of the Funds in this report had positive UNII balances, based on our best estimate, for tax purposes and positive UNII balances for financial reporting purposes.
 
COMMON SHARE EQUITY SHELF PROGRAMS
 
NQS, NMZ and NMD have each filed registration statements with the Securities and Exchange Commission (SEC) authorizing the Funds to issue additional common shares, through an equity shelf program. Under these equity shelf programs, the Funds, 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 each Fund’s NAV per common share.
 
During the current reporting period, NQS, NMZ and NMD sold common shares through their equity shelf programs at a weighted average premium to NAV per common share as shown in the accompanying table.

Risk Considerations
 
Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation. Past performance is no guarantee of future results. Fund common shares are subject to a variety of risks, including:
 
Investment, Market and Price Risk. An investment in common shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in common shares represents an indirect investment in the municipal securities owned by the Fund, which generally trade in the over-the-counter markets. Shares of closed-end investment companies like these Funds frequently trade at a discount to their net asset value (NAV). Your common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.
 
Leverage Risk. Each Fund’s use of leverage creates the possibility of higher volatility for the Fund’s per share NAV, market price, distributions and returns. There is no assurance that a Fund’s leveraging strategy will be successful.
 
Issuer Credit Risk. This is the risk that a security in a Fund’s portfolio will fail to make dividend or interest payments when due.
 
Credit Risk. An issuer of a bond held by a Fund may be unable to make interest and principal payments when due. A failure by the issuer to make such payments is called a “default”. A default can cause the price of the issuer’s bonds to plummet. Even if the issuer does not default, the prices of its bonds can fall if the market perceives that the risk of default is increasing.
 
Low-Quality Bond Risk. NMZ and NMD concentrate a large portion of their investments in low-quality municipal bonds (sometimes called “junk bonds”), which have greater credit risk and generally are less liquid and have more volatile prices than higher quality securities.

Nuveen Investments

 
 

 
 
Interest Rate Risk. Fixed-income securities such as bonds, preferred, convertible and other debt securities will decline in value if market interest rates rise.
 
Derivatives Risk. The Funds may use derivative instruments which involve a high degree of financial risk, including the risk that the loss on a derivative may be greater than the principal amount invested.
 
Inverse Floater Risk. The Funds may invest in inverse floaters. Due to their leveraged nature, these investments can greatly increase a Fund’s exposure to interest rate risk and credit risk. In addition, investments in inverse floaters involve the risk that the Fund could lose more than its original principal investment.
 
Reinvestment Risk. If market interest rates decline, income earned from a Fund’s portfolio may be reinvested at rates below that of the original bond that generated the income.
 
Call Risk or Prepayment Risk. Issuers may exercise their option to prepay principal earlier than scheduled, forcing a Fund to reinvest in lower-yielding securities.
 
Tax Risk. The tax treatment of Fund distributions may be affected by new IRS interpretations of the Internal Revenue Code and future changes in tax laws and regulations.
 
Below-Investment Grade Risk. Investments in securities below investment grade quality are predominantly speculative and subject to greater volatility and risk of default.
