Chairman’s

Letter to Shareholders

Dear Shareholders,

Investors have many reasons to remain cautious. The challenges in the Euro area are casting a shadow over global economies and financial markets. The political support for addressing fiscal issues is eroding as the economic and social impacts become more visible. At the same time, member nations appear unwilling to provide adequate financial support or to surrender sufficient sovereignty to strengthen the banks or unify the Euro area financial system. The gains made in reducing deficits, and the hard-won progress on winning popular acceptance of the need for economic austerity, are at risk. To their credit, European political leaders press on to find compromise solutions, but there is increasing concern that time will begin to run out.

In the U.S., strong corporate earnings have enabled the equity markets to withstand much of the downward pressures coming from weakening job creation, slower economic growth and political uncertainty. The Fed remains committed to low interest rates but has refrained from predicting another program of quantitative easing unless economic growth were to weaken significantly or the threat of recession appears on the horizon. Pre-election maneuvering has added to the already highly partisan atmosphere in the Congress. The end of the Bush-era tax cuts and implementation of the spending restrictions of the Budget Control Act of 2011, both scheduled to take place at year-end, loom closer.

During the last year, U.S. based investors have experienced a sharp decline and a strong recovery in the equity markets. The experienced investment teams at Nuveen keep their eye on a longer time horizon and use their practiced investment disciplines to negotiate through market peaks and valleys to achieve long-term goals for investors. Experienced professionals pursue investments that will weather short-term volatility and at the same time, seek opportunities that are created by markets that overreact to negative developments. Monitoring this process is an important consideration for the Fund Board as it oversees your Nuveen funds on your behalf.

As always, I encourage you to contact your financial consultant if you have any questions about your investment in a Nuveen Fund. On behalf of the other members of your Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Sincerely,

Robert P. Bremner

Chairman of the Board

Portfolio Managers’ Comments

Nuveen Quality Municipal Fund, Inc. (NQI)

Nuveen Municipal Opportunity Fund, Inc. (NIO)

Nuveen Premier Municipal Opportunity Fund, Inc. (NIF)

Nuveen Premium Income Municipal Opportunity Fund (NPX)

Nuveen Dividend Advantage Municipal Income Fund (NVG)

Nuveen AMT-Free Municipal Income Fund (NEA)

Portfolio managers Paul Brennan and Douglas White discuss key investment strategies and the six-month performance of these six national Funds. With 21 years of industry experience, including 15 years at Nuveen, Paul has managed NIO, NIF, NVG, and NEA since 2006. Douglas, who has 29 years of financial industry experience, assumed portfolio management responsibility for NQI and NPX in January 2011.

What key strategies were used to manage these Funds during the six-month reporting period ended April 30, 2012?

During this period, municipal bond prices generally rallied, amid strong demand and yield that continued to be historically low. The availability of municipal supply improved in recent months from 2011 levels, although the pattern of new issuance remained light compared with long-term historical trends. Due to their insured mandate and the continued severe decline in insured issuance, finding appropriate insured municipal bonds, especially new insured issues, remained a challenge for these Funds during the first two months of this period. Over the past few years, most municipal bond insurers had their credit ratings downgraded and only one insurer currently insures new municipal bonds. As a result, the supply of insured municipal securities decreased dramatically. During November and December 2011, issuance of new insured paper totaled just over $3 billion, accounting for approximately 4.5% of total municipal issuance during that time, compared with historical levels approaching 50%. The combination of comparatively light municipal supply, little insured issuance and relatively lower yields meant few attractive opportunities for these Funds during November and December 2011.

In view of this situation, in October 2011, the Funds’ Board of Directors/Trustees approved changes to the Funds’ investment policy regarding insured municipal securities. Effective January 2, 2012, the Funds eliminated the policy requiring them to invest at least 80% of their managed assets in municipal securities covered by insurance. This change was designed to provide more flexibility regarding the types of securities available for investment. This does not represent a change in investment objectives; each

Fund will continue to invest substantially all of its assets in a portfolio of investment-grade quality municipal securities.

Following the change to these Funds’ investment policy, our purchase activity increased, as we worked to enhance the Funds’ credit and sector diversification. One of the areas where we were more active was the health care sector, which had been underutilized in these Funds under the insured mandate and which we believed offered good opportunities. We also found value in water and sewer, transportation (particularly airports and toll roads), tobacco and higher education credits and in tax-supported bonds. Although the pattern of issuance tended to be shorter on the yield curve during this period due to an increase in refunding activity, our focus generally remained on longer maturities in order to take advantage of attractive yields at the longer end of the municipal yield curve. The purchase of longer bonds also provided some protection for the Funds’ duration and yield curve positioning. We also added slightly more yield to the Funds, buying bonds rated A and BBB. Overall, 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.

Cash for new purchases during this period was generated primarily by the proceeds from called and maturing bonds, which we worked to redeploy to keep the Funds fully invested. Approximately half of the new municipal bonds issued during this period came from borrowers that were calling existing debt and refinancing at lower rates. This refunding activity provided a meaningful source of liquidity, which was beneficial as we began to transition the Funds from insured to non-insured. In addition, NIF and NPX, which are now structured as Funds that do not hold any bonds subject to the alternative minimum tax (AMT), sold all of their AMT holdings by March 31, 2012, and reinvested the proceeds into bonds offering federal tax-exempt income. This provided additional opportunities to restructure these two Funds.

As of April 30, 2012, 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.

Lipper General & Insured Leveraged Municipal Debt Funds
Classification Average** 10.74% 23.04% 6.00% 6.68%

For the six months ended April 30, 2012, the cumulative returns on common share net asset value (NAV) for these six Funds exceeded the returns for the Standard & Poor’s (S&P) Municipal Bond Index and the S&P Municipal Bond Insured Index. For the same period, the Funds underperformed the average return for the Lipper General & Insured Leveraged Municipal Debt Funds Classification Average.

Key management factors that influenced the Funds’ returns during this period included duration and yield curve positioning, credit exposure and sector allocation. The use of regulatory leverage also was an important positive factor affecting the Funds’ performance. Leverage is discussed in more detail later in this report.

During this period, municipal bonds with longer maturities generally outperformed those with shorter maturities. 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. Among these Funds, NQI, NIF and NPX were the most advantageously positioned in terms of duration and yield curve exposure, with greater exposure to the longer parts of the yield curve that performed well. Holdings of non-callable zero coupon bonds, which outperformed during this period due to their long durations, also boosted the performance of NQI and NPX. In contrast, both NVG and NEA, which were introduced in March and November 2002, respectively, have reached the ten-year point

of the bond market cycle where holdings of bonds with short call dates typically increases. This hampered their performance during this period. NEA, which had the shortest duration among the six Funds, was the most negatively impacted by its positioning. In general, variations in duration and yield curve positioning among the Funds accounted for the majority of the differences in performance.

Credit exposure was also an important factor in 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. Over the past few years, bonds that matured or were called from these Funds’ portfolios and not replaced due to the insured mandate caused their credit weightings to shift toward the upper end of the quality spectrum. While we added to the Funds’ lower rated holdings following the change in investment policy, these Funds generally continued to be significantly overweight in bonds rated AA, which detracted from their performance during this period. NEA’s performance also was hampered by the largest exposure to AAA rated bonds among these six Funds. These allocations were offset to a certain extent by the positive influence of the Funds’ exposures to the lower rated credit spectrum.

Holdings that generally made positive contributions to the Funds’ returns during this period included health care (including hospitals), transportation and education credits. All of these Funds, particularly NQI, NPX and NVG, benefited from their weightings in the health care sector. In addition, the returns of NQI and NPX were boosted by their holdings of toll road bonds. Tobacco bonds backed by the 1998 master settlement agreement also were one of the top performing market segments, as these bonds benefited from several market developments, including increased demand for higher-yielding investments by investors who became 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. Benefiting from the recent change in investment policy, NIO, NIF, NVG and NEA now have allocations in lower rated tobacco bonds as of April 30, 2012. NQI and NPX do not hold any lower rated tobacco bonds.

8 Nuveen Investments

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, 2012, NEA had the largest exposure to pre-refunded bonds, while NQI had the smallest allocation. General obligation and other tax-supported bonds as well as utilities and housing credits also lagged the performance of the general municipal market for this period. These Funds generally had relatively light exposures to housing, which limited the impact of the performance of this sector.

FUND POLICY CHANGES

On October 28, 2011, the Funds’ Board of Directors/Trustees approved changes to each Fund’s investment policy regarding its investment in insured municipal securities. These changes were designed to provide the Adviser with more flexibility regarding the types of securities available for investment by each Fund.

Effective January 2, 2012, each Fund eliminated the investment policy requiring it, under normal circumstances, to invest at least 80% of its managed assets in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. Over the past few years, most municipal bond insurers have had their credit ratings downgraded and only one insurer is currently insuring new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically and the long-term viability of the municipal bond insurance market is uncertain. The Funds have not changed their investment objective and will continue to invest substantially all of their assets in a portfolio of investment grade quality municipal securities.

Concurrent with the investment policy changes, the Funds have changed their names as follows:

Nuveen Insured Quality Municipal Fund, Inc. (NQI) changed to Nuveen Quality Municipal Fund, Inc. (NQI)
Nuveen Insured Municipal Opportunity Fund, Inc. (NIO) changed to Nuveen Municipal Opportunity Fund, Inc. (NIO)
Nuveen Premier Insured Municipal Income Fund, Inc. (NIF) changed to Nuveen Premier Municipal Opportunity Fund, Inc. (NIF)

Nuveen Investments 9

Nuveen Insured Premium Income Municipal Fund 2 (NPX) changed to Nuveen Premium Income Municipal Opportunity Fund (NPX)
Nuveen Insured Dividend Advantage Municipal Fund (NVG) changed to Nuveen Dividend Advantage Municipal Income Fund (NVG); and
Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) changed to Nuveen AMT-Free Municipal Income Fund (NEA)

In addition, each Fund changed its non-fundamental investment policy requiring each Fund to invest in municipal securities rated at least investment grade at the time of investment. Each Fund adopted a new policy to, under normal circumstances, invest at least 80% of its managed assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical ratings organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Fund’s investment adviser. Under the new policy, each Fund may invest up to 20% of its managed assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Fund’s investment adviser. No more than 10% of each Fund’s managed assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Fund’s investment adviser.

APPROVED FUND REORGANIZATIONS

On June 22, 2012, the Funds’ Board of Directors/Trustees approved a series of reorganizations for certain Funds included in this report. The reorganizations are intended to create a single larger 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

10 Nuveen Investments

● Increased Fund flexibility in managing the structure and cost of leverage over time.

The approved reorganizations are as follows:

Acquired Funds Symbol Acquiring Fund Symbol
Nuveen Premier Municipal NIF
Opportunity Fund, Inc. Nuveen AMT-Free Municipal NEA
Nuveen Premier Income NPX Income Fund
Municipal Opportunity Fund

If shareholders approve the reorganizations, and upon the closing of the reorganizations, the Acquired Funds will transfer substantially all of their assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund, and the assumption by the Acquiring Fund of the liabilities of the Acquired Funds. The Acquired Funds will then be liquidated, dissolved and terminated in accordance with their Declaration of Trust.

Fund Leverage and Other Information

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.

THE FUNDS’ REGULATORY LEVERAGE

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 and Market 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. 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.

Price Risk. Shares of closed-end investment companies like these Funds frequently trade at a discount to their 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.

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.

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.

Interest Rate Risk. Fixed-income securities such as bonds, preferred, convertible and other debt securities will decline in value if market interest rates rise.

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.

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.

Common Share Dividend and

Price Information

DIVIDEND INFORMATION

The monthly dividends of all six Funds in this report remained stable throughout the six-month reporting period ended April 30, 2012.

Due to normal portfolio activity, common shareholders of the following Funds received capital gains and/or net ordinary income distributions in December 2011 as follows:

Long-Term Capital Gains and/or Ordinary Income
(per share) (per share)
NQI $ 0.0026
NIO $ 0.0026
NVG $ 0.0413

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, pay all of its net investment income as dividends to shareholders. As of April 30, 2012, all six of the Funds in this report had positive UNII balances, based upon our best estimate, for tax purposes and positive UNII balances for financial reporting purposes.

COMMON SHARE REPURCHASES AND PRICE INFORMATION

As of April 30, 2012, and since the inception of the Funds’ repurchase programs, the Funds have cumulatively repurchased and retired their common shares as shown in the accompanying table. Since the inception of the Funds’ repurchase programs, NQI, NIF, and NPX have not repurchased any of their outstanding common shares.

Common Shares % of Outstanding
Fund Repurchased and Retired Common Shares
NIO 2,900 0.0%
NVG 10,400 0.0%
NEA 19,300 0.1%

During the six-month reporting period, the Funds did not repurchase and retire any of their outstanding common shares.

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

  1. General Information and Significant Accounting Policies

General Information

The funds covered in this report and their corresponding Common share stock exchange symbols are Nuveen Quality Municipal Fund, Inc. (NQI), Nuveen Municipal Opportunity Fund, Inc. (NIO), Nuveen Premier Municipal Opportunity Fund, Inc. (NIF), Nuveen Premium Income Municipal Opportunity Fund (NPX), Nuveen Dividend Advantage Municipal Income Fund (NVG) and Nuveen AMT-Free Municipal Income Fund (NEA) (each a “Fund” and collectively, the “Funds”). Common shares of Quality (NQI), Opportunity (NIO), Premier Opportunity (NIF) and Premium Opportunity (NPX) are traded on the New York Stock Exchange (“NYSE”) while Common shares of Dividend Advantage (NVG) and AMT-Free Income (NEA) are traded on the NYSE Amex. The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end registered investment companies.

Each Fund seeks to provide current income exempt from regular federal income tax, and in the case of AMT-Free Income (NEA) the alternative minimum tax applicable to individuals, by investing primarily in a portfolio of municipal obligations issued by state and local government authorities or certain U.S. territories.

Policy Changes

On October 28, 2011, the Funds’ Board of Directors/Trustees approved changes to each Fund’s investment policy regarding its investment in insured municipal securities. These changes were designed to provide Nuveen Fund Advisors, Inc. (the “Adviser”), a wholly-owned subsidiary of Nuveen Investments Inc. (“Nuveen”), with more flexibility regarding the types of securities available for investment by each Fund.

On January 2, 2012, each Fund eliminated the investment policy requiring it, under normal circumstances, to invest at least 80% of its managed assets (as defined in Footnote 7 – Management Fees and Other Transactions with Affiliates) in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. Since 2007, most municipal bond insurers have had their credit ratings downgraded and only one insurer is currently insuring new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically and the long-term viability of the municipal bond insurance market is uncertain. The Funds did not change their investment objective and continue to invest substantially all of their assets in a portfolio of investment grade quality municipal securities.

Concurrent with the investment policy changes, the Funds changed their names as follows:

Nuveen Insured Quality Municipal Fund, Inc. (NQI) changed to Nuveen Quality Municipal Fund, Inc. (NQI),
Nuveen Insured Municipal Opportunity Fund, Inc. (NIO) changed to Nuveen Municipal Opportunity Fund, Inc. (NIO),
Nuveen Premier Insured Municipal Income Fund, Inc. (NIF) changed to Nuveen Premier Municipal Opportunity Fund, Inc. (NIF),
Nuveen Insured Premium Income Municipal Fund 2 (NPX) changed to Nuveen Premium Income Municipal Opportunity Fund, Inc. (NPX),
Nuveen Insured Dividend Advantage Municipal Fund (NVG) changed to Nuveen Dividend Advantage Municipal Income Fund (NVG) and
Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) changed to Nuveen AMT-Free Municipal Income Fund (NEA).

In addition, each Fund changed its non-fundamental investment policy requiring each Fund to invest in municipal securities rated at least investment grade at the time of investment. Each Fund adopted a new policy to, under normal circumstances, invest at least 80% of its managed assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical ratings organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Adviser. Under the new policy, each Fund may invest up to 20% of its managed assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Adviser. No more than 10% of each Fund’s managed assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Adviser.

Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Investment Valuation

Prices of municipal bonds are provided by a pricing service approved by the Funds’ Board of Directors/Trustees. These securities are generally classified as Level 2 for fair value measurement purposes. 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. 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 priority of the significant inputs. Investments in investment companies are valued at their respective net asset values on the valuation date. These investment vehicles are generally classified as Level 1.

Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Funds’ Board of Directors/Trustees or its designee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s net asset value (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 priority of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Funds’ Board of Directors/Trustees or its designee.

Refer to Footnote 2 – Fair Value Measurements for further details on the leveling of securities held by the Funds as of the end of the reporting period.

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 instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. At April 30, 2012, Quality (NQI), Opportunity (NIO), Premier Opportunity (NIF), Dividend Advantage (NVG) and AMT-Free Income (NEA) had outstanding when-issued/delayed delivery purchase commitments of $7,696,956, $45,276,790, $2,750,350, $10,353,996 and $14,875,520, respectively. There were no such outstanding purchase commitments in Premium Opportunity (NPX).

Investment Income

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

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. Legal fee refund presented in the Statement of Operations reflects a refund of workout expenditures paid in a prior reporting period.

Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies (“RICs”). Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income tax, and in the case of AMT-Free Income (NEA) the alternative minimum tax applicable to individuals, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.

For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Financial Statements (Unaudited) (continued)

Dividends and Distributions to Common Shareholders

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

Distributions to Common shareholders of net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Auction Rate Preferred Shares

Each Fund is authorized to issue Auction Rate Preferred Shares (“ARPS”). As of October 31, 2011, the Funds redeemed all of their outstanding ARPS, at liquidation value.

MuniFund Term Preferred Shares

The following Funds have issued and outstanding MuniFund Term Preferred (“MTP”) Shares, with a $10 stated (“par”) value per share. Proceeds from the issuance of MTP Shares, net of offering expenses, were used to redeem all, or a portion of, each Fund’s outstanding ARPS. Each Fund’s MTP Shares are issued in one Series. Dividends on MTP Shares, which are recognized as interest expense for financial reporting purposes, are paid monthly at a fixed annual rate, subject to adjustments in certain circumstances. The MTP Shares trade on the NYSE. As of April 30, 2012, the number of MTP Shares outstanding, annual interest rate and the NYSE “ticker” symbol for each Fund’s series of MTP Shares are as follows:

Dividend Advantage (NVG)
Annual Annual
Shares Interest NYSE Shares Interest NYSE
Outstanding Rate Ticker Outstanding Rate Ticker
Series:
2014 10,800,000 2.95 % NVG Pr C — %
2015 8,300,000 2.85 NEA Pr C

Each Fund is obligated to redeem its MTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed or repurchased by the Fund. MTP Shares are subject to optional and mandatory redemption in certain circumstances. MTP Shares will be subject to redemption at the option of each Fund (“Optional Redemption Date”), subject to a payment of premium for one year following the Optional Redemption Date (“Premium Expiration Date”), and at par thereafter. MTP Shares also will be subject to redemption, at the option of each Fund, at par in the event of certain changes in the credit rating of the MTP Shares. Each Fund may be obligated to redeem certain of the MTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. The Term Redemption Date, Optional Redemption Date and Premium Expiration Date for each Fund’s series of MTP Shares are as follows:

Dividend — Advantage AMT-Free — Income
(NVG ) (NEA )
Series 2014 Series 2015
Term Redemption Date November 1, 2014 February 1, 2015
Optional Redemption Date November 1, 2010 February 1, 2011
Premium Expiration Date October 31, 2011 January 31, 2012

The average liquidation value for all series of MTP Shares outstanding for each Fund during the six months ended April 30, 2012, was as follows:

Advantage AMT-Free — Income
(NVG ) (NEA )
Average liquidation value of MTP Shares outstanding $ 108,000,000 $ 83,000,000

For financial reporting purposes only, the liquidation value of MTP Shares is recorded as a liability on the Statement of Assets and Liabilities. Unpaid dividends on MTP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on MTP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Nuveen has agreed that net amounts earned by Nuveen as underwriter of each Fund’s MTP Share offering would be credited to the Funds, and would be recorded as reductions of offering costs recognized by the Funds. During the six months ended April 30, 2012, Nuveen earned no net underwriting amounts on the Funds’ MTP Shares.

Variable Rate MuniFund Term Preferred Shares

The following Funds have issued and outstanding Variable Rate MuniFund Term Preferred (“VMTP”) Shares, with $100,000 liquidation value per share. Quality (NQI), Dividend Advantage (NVG) and AMT-Free Income (NEA) issued their VMTP Shares in a privately negotiated offering during February 2011, September 2011 and July 2011, respectively. Proceeds from the issuance of VMTP Shares, net of offering expenses, were used to redeem all or a portion of, the remainder of each Fund’s outstanding ARPS. Each Fund’s VMTP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. As of April 30, 2012, the number of VMTP Shares outstanding, at liquidation value, for each Fund is as follows:

Quality Dividend — Advantage AMT-Free — Income
(NQI ) (NVG ) (NEA )
Series 2014 $ 240,400,000 $ 92,500,000 $ 67,600,000

Each Fund is obligated to redeem its VMTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed or repurchased by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances . The VMTP Shares are subject to redemption at the option of each Fund (“Optional Redemption Date”), subject to payment of premium for one year following the Optional Redemption Date (“Premium Expiration Date”), and at par thereafter. Each Fund may be obligated to redeem certain of the VMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. The Term Redemption Date, Optional Redemption Date and Premium Expiration Date for each Fund’s VMTP Shares are as follows:

Quality Dividend — Advantage AMT-Free — Income
(NQI ) (NVG ) (NEA )
Term Redemption Date March 1, 2014 October 1, 2014 August 1, 2014
Optional Redemption Date March 1, 2012 October 1, 2012 August 1, 2012
Premium Expiration Date February 29, 2012 September 30, 2012 July 31, 2012

The average liquidation value of VMTP Shares outstanding and annualized dividend rate of VMTP Shares for each Fund during the six months ended April 30, 2012, were as follows:

Quality Dividend — Advantage AMT-Free — Income
(NQI ) (NVG ) (NEA )
Average liquidation Value of VMTP Shares outstanding $ 240,400,000 $ 92,500,000 $ 67,600,000
Annualized dividend rate 1.39 % 1.14 % 1.19 %

Dividends on the VMTP Shares (which are treated as interest payments for financial reporting purposes) are set weekly.

For financial reporting purposes only, the liquidation value of VMTP Shares is recorded as a liability on the Statement of Assets and Liabilities. Unpaid dividends on VMTP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on VMTP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Variable Rate Demand Preferred Shares

The following Funds have issued and outstanding Variable Rate Demand Preferred (“VRDP”) Shares, with a $100,000 liquidation value per share. Opportunity (NIO), Premier Opportunity (NIF) and Premium Opportunity (NPX) issued their VRDP Shares in a privately negotiated offering during December 2010, December 2010 and August 2008, respectively. Concurrent with renewing agreements with the liquidity provider for its VRDP Shares in June 2010, Premium Opportunity (NPX) exchanged all its 2,190 Series 1 VRDP Shares for 2,190 Series 2 VRDP Shares. The principal difference in terms between Series 1 and Series 2 VRDP Shares is the requirement that the Fund redeem VRDP Shares owned by the liquidity provider if the VRDP Shares have been owned by the liquidity provider through six months of continuous, unsuccessful remarketing. Proceeds of each Fund’s offering were used to redeem all or a portion of, the remainder of each Fund’s outstanding ARPS. The VRDP Shares were offered to qualified institutional buyers

Nuveen Investments 103

Notes to
Financial Statements (Unaudited) (continued)

pursuant to Rule 144A under the Securities Act of 1933. As of April 30, 2012, the number of VRDP Shares outstanding and maturity date for each Fund are as follows:

Opportunity Premier — Opportunity Premium — Opportunity
(NIO ) (NIF ) (NPX )
Series 1 1 2
Shares outstanding 6,672 1,309 2,190
Maturity December 1, 2040 December 1, 2040 August 1, 2038

VRDP Shares include a liquidity feature that allows VRDP shareholders to have their shares purchased by a liquidity provider with whom each Fund has contracted in the event that purchase orders for VRDP Shares in a remarketing are not sufficient in number to be matched with the sale orders in that remarketing. Each Fund is required to redeem any VRDP Shares that are still owned by the liquidity provider after six months of continuous, unsuccessful remarketing.

Dividends on the VRDP Shares (which are treated as interest payments for financial reporting purposes) are set weekly at a rate established by a remarketing agent; therefore, the market value of the VRDP Shares is expected to approximate its liquidation value. If remarketings for VRDP Shares are continuously unsuccessful for six months, the maximum rate is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the VRDP Shares.

Subject to certain conditions, VRDP Shares may be redeemed, in whole or in part, at any time at the option of each Fund. Each Fund may also redeem certain of the VRDP Shares if the Fund fails to maintain certain asset coverage requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends.

The average liquidation value outstanding and annualized dividend rate of VRDP Shares for each Fund during the six months ended April 30, 2012, were as follows:

Opportunity Premier — Opportunity Premium — Opportunity
(NIO ) (NIF ) (NPX )
Average liquidation value outstanding 667,200,000 130,900,000 219,000,000
Annualized dividend rate 0.28 % 0.28 % 0.27 %

For financial reporting purposes only, the liquidation value of VRDP Shares is recognized as a liability on the Statement of Assets and Liabilities. Unpaid dividends on VRDP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on the VRDP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. In addition to interest expense, each Fund also pays a per annum liquidity fee to the liquidity provider as well as a remarketing fee, which are recognized as components of “Fees on VRDP Shares” on the Statement of Operations.

Insurance

Since 2007, the financial status of most major municipal bond insurers has deteriorated substantially, and some insurers have gone out of business, rendering worthless the insurance policies they had written. Under normal circumstances, and during the period November 1, 2011 through January 2, 2012, each Fund invests at least 80% of its managed assets (as defined in Footnote 7 – Management Fees and Other Transactions with Affiliates) in municipal securities that were covered by insurance guaranteeing the timely payment of principal and interest. In addition, during the period November 1, 2011 through January 2, 2012, each Fund invested in municipal securities that, at the time of investment was rated investment grade (including (i) bonds insured by investment grade rated insurers or are rated investment grade; (ii) unrated bonds that are judged to be investment grade by the Adviser; and (iii) escrowed bonds). Ratings below BBB by one or more national rating agencies are considered to be below investment grade.

Inverse Floating Rate Securities

Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. In turn, this trust (a) issues floating rate certificates, in face amounts equal to some fraction of the deposited bond’s par amount or market value, that typically pay short-term tax-exempt interest rates to third parties, and (b) issues to a long-term investor (such as one of the Funds) an inverse floating rate certificate (sometimes referred to as an “inverse floater”) that represents all remaining or residual interest in the trust. The income received by the inverse floater holder varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the inverse floater holder bears substantially all of the underlying bond’s downside investment risk and also benefits disproportionately from any potential appreciation of the underlying bond’s value. The price of an inverse floating rate security will be more volatile than that of the underlying bond because the interest rate is dependent on not only the fixed coupon rate of the

104 Nuveen Investments

underlying bond but also on the short-term interest paid on the floating rate certificates, and because the inverse floating rate security essentially bears the risk of loss of the greater face value of the underlying bond.

A Fund may purchase an inverse floating rate security in a secondary market transaction without first owning the underlying bond (referred to as an “externally-deposited inverse floater”), or instead by first selling a fixed-rate bond to a broker-dealer for deposit into the special purpose trust and receiving in turn the residual interest in the trust (referred to as a “self-deposited inverse floater”). The inverse floater held by a Fund gives the Fund the right (a) to cause the holders of the floating rate certificates to tender their notes at par, and (b) to have the broker transfer the fixed-rate bond held by the trust to the Fund, thereby collapsing the trust. An investment in an externally-deposited inverse floater is identified in the Portfolio of Investments as “(IF) – Inverse floating rate investment.” An investment in a self-deposited inverse floater is accounted for as a financing transaction. In such instances, a fixed-rate bond deposited into a special purpose trust is identified in the Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund accounting for the short-term floating rate certificates issued by the trust as “Floating rate obligations” on the Statement of Assets and Liabilities. In addition, the Fund reflects in “Investment Income” the entire earnings of the underlying bond and recognizes the related interest paid to the holders of the short-term floating rate certificates as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

During the six months ended April 30, 2012, each Fund invested in externally-deposited inverse floaters and/or self-deposited inverse floaters.

Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a “recourse trust” or “credit recovery swap”) (such agreements referred to herein as “Recourse Trusts”) with a broker-dealer by which a Fund agrees to reimburse the broker-dealer, in certain circumstances, for the difference between the liquidation value of the fixed-rate bond held by the trust and the liquidation value of the floating rate certificates issued by the trust plus any shortfalls in interest cash flows. Under these agreements, a Fund’s potential exposure to losses related to or on inverse floaters may increase beyond the value of a Fund’s inverse floater investments as a Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates. At period end, any such shortfall is recognized as “Unrealized depreciation on Recourse Trusts” on the Statement of Assets and Liabilities.

At April 30, 2012, each Fund’s maximum exposure to externally-deposited Recourse Trusts, was as follows:

Quality Opportunity Opportunity Premier Opportunity Premium Dividend — Advantage AMT-Free — Income
(NQI ) (NIO ) (NIF ) (NPX ) (NVG ) (NEA )
Maximum exposure to Recourse Trusts $ 26,610,000 $ 40,430,000 $ 15,375,000 $ 14,845,000 $ 6,665,000 $ 6,665,000

The average floating rate obligations outstanding and average annual interest rate and fees related to self-deposited inverse floaters during the six months ended April 30, 2012, were as follows:

Quality Opportunity Opportunity Premier Opportunity Premium Dividend — Advantage AMT-Free — Income
(NQI ) (NIO ) (NIF ) (NPX ) (NVG ) (NEA )
Average floating rate obligations outstanding $ 52,456,099 $ 105,390,614 $ 19,000,000 $ 56,858,132 $ 28,413,334 $ 13,040,000
Average annual interest rate and fees 0.48 % 0.52 % 0.46 % 0.46 % 0.58 % 0.61 %

Derivative Financial Instruments

Each Fund is authorized to invest in certain derivative instruments, including foreign currency forwards, futures, options and swap contracts. Although the Funds are authorized to invest in such financial instruments, and may do so in the future, they did not make any such investments during the six months ended April 30, 2012.

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. Futures contracts, when applicable, expose a Fund to minimal counterparty credit risk as they are exchange traded and the exchange’s clearinghouse, which is counterparty to all exchange traded futures, guarantees the futures contracts against default.

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-

Nuveen Investments 105

Notes to
Financial Statements (Unaudited) (continued)

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.

Zero Coupon Securities

Each Fund is authorized to invest in zero coupon securities. A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Tax-exempt 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.

Offering Costs

Costs incurred by Dividend Advantage (NVG) and AMT-Free Income (NEA) in connection with their offerings of MTP Shares ($1,875,000 and $1,605,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Costs incurred by Quality (NQI), Dividend Advantage (NVG) and AMT-Free Income (NEA) in connection with their VMTP Shares ($1,120,000, $485,000 and $180,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Costs incurred by Opportunity (NIO), Premier Opportunity (NIF) and Premium Opportunity (NPX) in connection with their offerings of VRDP Shares ($2,645,000, $755,000 and $2,535,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Each Fund’s amortized deferred charges are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by net credits earned on each Fund’s cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the custodian bank.

Indemnifications

Under the Funds’ organizational documents, their officers and directors/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.

Use of Estimates

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

  1. Fair Value Measurements

Fair value is defined as the price that the Funds would receive 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 three-tier hierarchy of inputs is summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical securities.
Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3 – Significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

  1. Derivative Instruments and Hedging Activities

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. The Funds did not invest in derivative instruments during the six months ended April 30, 2012.

  1. Income Tax Information

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset values of the Funds.

  1. Management Fees and Other Transactions with Affiliates

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 for each Fund, payable monthly, is calculated according to the following schedule:

Quality (NQI)
Opportunity (NIO)
Premier Opportunity (NIF)
Premium Opportunity (NPX)
Average Daily Managed Assets* Fund-Level Fee Rate
For the first $125 million .4500 %
For the next $125 million .4375
For the next $250 million .4250
For the next $500 million .4125
For the next $1 billion .4000
For the next $3 billion .3875
For managed assets over $5 billion .3750

For the next $500 million .4125
For the next $1 billion .4000
For managed assets over $2 billion .3750

Nuveen Investments 111

Notes to
Financial Statements (Unaudited) (continued)

The annual complex-level fee for each Fund, payable monthly, is calculated according to the following schedule:

Complex-Level Managed Asset Breakpoint Level* Effective Rate at Breakpoint Level
$55 billion .2000 %
$56 billion .1996
$57 billion .1989
$60 billion .1961
$63 billion .1931
$66 billion .1900
$71 billion .1851
$76 billion .1806
$80 billion .1773
$91 billion .1691
$125 billion .1599
$200 billion .1505
$250 billion .1469
$300 billion .1445
  • For the fund-level and complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen Funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen Funds or assets in excess of $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 April 30, 2012, the complex-level fee rate for these Funds was .1724%.

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser is responsible for each Fund’s overall strategy and asset allocation decisions. The Adviser has entered into sub-advisory agreements with Nuveen Asset Management, LLC (“the Sub-Adviser”), a wholly-owned subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser.

The Funds pay no compensation directly to those of its directors/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 of Directors/Trustees has adopted a deferred compensation plan for independent directors/trustees that enables directors/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.

For the first ten years of Dividend Advantage’s (NVG) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily managed assets, for fees and expenses in the amounts and for the time periods set forth below:

Year Ending — March 31, Year Ending — March 31,
2002* .30 % 2008 .25 %
2003 .30 2009 .20
2004 .30 2010 .15
2005 .30 2011 .10
2006 .30 2012 .05
2007 .30
  • From the commencement of operations.

The Adviser has not agreed to reimburse Dividend Advantage (NVG) for any portion of its fees and expenses beyond March 31, 2012.

  1. New Accounting Pronouncements

Fair Value Measurements and Disclosures

On May 12, 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04 (“ASU No. 2011-04”) modifying Topic 820, Fair Value Measurements and Disclosures . At the same time, the International Accounting Standards Board (“IASB”) issued International Financial Reporting Standard (“IFRS”) 13, Fair Value Measurement. The objective of the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, ASU No. 2011-04 requires reporting entities to disclose i) the amounts of any transfers between Level 1 and Level 2 and the reasons for the transfers and ii) for Level 3 fair value measurements, a) quantitative information about significant

112 Nuveen Investments

unobservable inputs used, b) a description of the valuation processes used by the reporting entity and c) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of ASU No. 2011-04 is for interim and annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this guidance and the impact it will have to the financial statement amounts and footnote disclosures, if any.

  1. Subsequent Event

Approved Fund Reorganizations

On June 22, 2012, the Funds’ Board of Directors/Trustees approved a series of reorganizations for certain Funds included in this report. The reorganizations are intended to create a single larger 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 approved reorganizations are as follows:

Acquired Funds Acquiring Fund
Premier Opportunity (NIF) ● AMT-Free Income (NEA)
Premium Opportunity (NPX)

If shareholders approve the reorganizations, and upon the closing of the reorganizations, the Acquired Funds will transfer substantially all of their assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund, and the assumption by the Acquiring Fund of the liabilities of the Acquired Funds. The Acquired Funds will then be liquidated, dissolved and terminated in accordance with their Declaration of Trust.

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 month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.

How shares are purchased

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

114 Nuveen Investments

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.

Glossary of Terms

Used in this Report

Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have “failed,” with current holders receiving a formula-based interest rate until the next scheduled auction.
Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.
Average Effective Maturity: The market-value-weighted average of the effective maturity dates of the individual securities including cash. In the case of a bond that has been advance-refunded to a call date, the effective maturity is the date on which the bond is scheduled to be redeemed using the proceeds of an escrow account. In most other cases the effective maturity is the stated maturity date of the security.
Effective Leverage: Effective leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative investments in the Fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.
Inverse Floating Rate Securities: Inverse floating rate securities, also known as inverse floaters or tender option bonds (TOBs), are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a Fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.

Leverage: Using borrowed money to invest in securities or other assets, seeking to increase the return of an investment or portfolio.
Leverage-Adjusted Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond Fund’s value to changes when market interest rates change. Generally, the longer a bond’s or Fund’s duration, the more the price of the bond or Fund will change as interest rates change. Leverage-adjusted duration takes into account the leveraging process for a Fund and therefore is longer than the duration of the Fund’s portfolio of bonds.
Lipper General & Insured Leveraged Municipal Debt Funds Classification Average: Calculated using the returns of all closed-end funds in this category. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charges.
Market Yield (also known as Dividend Yield or Current Yield): An investment’s current annualized dividend divided by its current market price.
Net Asset Value (NAV): The net market value of all securities held in a portfolio.
Net Asset Value (NAV) Per Share: The market value of one share of a mutual fund or closed-end fund. For a Fund, the NAV is calculated daily by taking the Fund’s total assets (securities, cash, and accrued earnings), subtracting the Fund’s liabilities, and dividing by the number of shares outstanding.
Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.
Regulatory Leverage: Regulatory Leverage consists of preferred shares issued by or borrowings of a Fund. Both of these are part of a Fund’s capital structure. Regulatory leverage is sometimes referred to as “‘40 Act Leverage” and is subject to asset coverage limits set in the Investment Company Act of 1940.
Standard & Poor’s (S&P) Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment-grade U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
Standard & Poor’s (S&P) Municipal Bond Insured Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, insured U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
Taxable-Equivalent Yield: The yield necessary from a fully taxable investment to equal, on an after-tax basis, the yield of a municipal bond investment.

Glossary of Terms

Used in this Report (continued)

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