INVESTMENT ADVISER NAME CHANGE
 
Effective January 1, 2011, Nuveen Asset Management, the Funds’ investment adviser, changed its name to Nuveen Fund Advisors, Inc. (“Nuveen Fund Advisors”).Concurrently, Nuveen Fund Advisors formed a wholly-owned subsidiary, Nuveen Asset Management, LLC, to house its portfolio management capabilities.
 
NUVEEN INVESTMENTS COMPLETES STRATEGIC COMBINATION WITH FAF ADVISORS
 
On December 31, 2010, Nuveen Investments completed the strategic combination between Nuveen Asset Management, LLC, the largest investment affiliate of Nuveen Investments, and FAF Advisors. As part of this transaction, U.S. Bancorp – the parent of FAF Advisors – received cash consideration and a 9.5% stake in Nuveen Investments in exchange for the long-term investment business of FAF Advisors, including investment management responsibilities for the non-money market mutual funds of the First American Funds family.
 
The approximately $27 billion of mutual fund and institutional assets managed by FAF Advisors, along with the investment professionals managing these assets and other key personnel, have become part of Nuveen Asset Management, LLC. With these additions to Nuveen Asset Management, LLC, this affiliate now manages more than $100 billion of assets across a broad range of strategies from municipal and taxable fixed income to traditional and specialized equity investments.
 
This combination does not affect the investment objectives or strategies of the Funds in this report. Over time, Nuveen Investments expects that the combination will provide even more ways to meet the needs of investors who work with financial advisors and consultants by enhancing the multi-boutique model of Nuveen Investments, which also includes highly respected investment teams at HydePark, NWQ Investment Management, Santa Barbara Asset Management, Symphony Asset Management, Tradewinds Global Investors and Winslow Capital. Nuveen Investments managed approximately $206 billion of assets as of March 31, 2011.

Chairman’s
Letter to Shareholders
 
 
Dear Shareholders,
 
In 2010, the global economy recorded another year of recovery from the financial and economic crises of 2008, but many of the factors that caused the downturn still weigh on the prospects for continued improvement. In the U.S., ongoing weakness in housing values has put pressure on homeowners and mortgage lenders. Similarly, the strong earnings recovery for corporations and banks is only slowly being translated into increased hiring or more active lending. Globally, deleveraging by private and public borrowers has inhibited economic growth and that process is far from complete.
 
Encouragingly, constructive actions are being taken by governments around the world to deal with economic issues. In the U.S., the recent passage of a stimulatory tax bill relieved some of the pressure on the Federal Reserve to promote economic expansion through quantitative easing and offers the promise of sustained economic growth. A number of European governments are undertaking programs that could significantly reduce their budget deficits. Governments across the emerging markets are implementing various steps to deal with global capital flows without undermining international trade and investment.
 
The success of these government actions could determine whether 2011 brings further economic recovery and financial market progress. One risk associated with the extraordinary efforts to strengthen U.S. economic growth is that the debt of the U.S. government will continue to grow to unprecedented levels. Another risk is that over time there could be inflationary pressures on asset values in the U.S. and abroad, because what happens in the U.S. impacts the rest of the world economy. Also, these various actions are being taken in a setting of heightened global economic uncertainty, primarily about the supplies of energy and other critical commodities. In this challenging environment, your Nuveen investment team continues to seek sustainable investment opportunities and to remain alert to potential risks in a recovery still facing many headwinds. On your behalf, we monitor their activities to assure they maintain their investment disciplines.
 
As you will note elsewhere in this report, on December 31, 2010, Nuveen Investments completed a strategic combination with FAF Advisors, Inc., the manager of the First American Funds. The combination adds highly respected and distinct investment teams to meet the needs of investors and their advisors and is designed to benefit all fund shareholders by creating a fund organization with the potential for further economies of scale and the ability to draw from even greater talent and expertise to meet those investor needs.
 
As of the end of June 2011, Nuveen Investments had completed the refinancing of all of the Auction Rate Preferred Securities issued by its taxable closed-end funds and 91% of the MuniPreferred shares issued by its tax-exempt closed-end funds. Please consult the Nuveen Investments web site, www.Nuveen.com, for the current status of this important refinancing program.
 
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

Portfolio Managers’ Comments
 
Nuveen Insured Quality Municipal Fund, Inc. (NQI)
Nuveen Insured Municipal Opportunity Fund, Inc. (NIO)
Nuveen Premier Insured Municipal Income Fund, Inc. (NIF)
Nuveen Insured Premium Income Municipal Fund 2 (NPX)
Nuveen Insured Dividend Advantage Municipal Fund (NVG)
Nuveen Insured Tax-Free Advantage Municipal Fund (NEA)
 
Portfolio managers Paul Brennan and Douglas White review key investment strategies and the six-month performance of these six national insured Funds. With 20 years of industry experience, including 14 years at Nuveen, Paul has managed NIO, NIF, NVG and NEA since 2006. Douglas, who has 28 years of financial industry experience, assumed portfolio management responsibility for NQI and NPX from Paul in January 2011.
 
What key strategies were used to manage these Funds during the six-month reporting period ended April 30, 2011?
 
After rallying through most of 2010, municipal bond prices declined during this six-month period, impacted by investor concerns about inflation, the federal deficit and the deficit’s impact on demand for U.S. Treasury securities. Adding to this market pressure was media coverage of the strained finances of many state and local governments. As a result, money began to flow out of municipal bond funds, as yields rose and valuations declined. Toward the end of this period, we saw the environment in the municipal market improve, as some buyers were attracted by municipal bond valuations and yields, resulting in declining yields and rising valuations.
 
The municipal bond market also was affected by a significant decline in new tax-exempt issuance during this period. One reason for this decrease was the heavy issuance of taxable municipal debt at the end of 2010 under the Build America Bond (BAB) program. During November and December 2010, taxable BABs issuance nationwide totaled $31.5 billion, accounting for 34.5% of new bonds in the municipal market. Since interest payments from BABs represent taxable income, we did not view these bonds as appropriate investment opportunities for these Funds. The BAB program expired December 31, 2010, after Congress failed to include legislation extending the program in the tax bill it passed earlier that month. In addition to the BAB program’s impact on tax-exempt issuance during the November-December period, borrowers trying to take advantage of the program’s favorable terms before its termination at year end accelerated issuance that potentially would have come to market as tax-exempt bonds in 2011, choosing instead to issue taxable BABs during the last two months of 2010. Due in part to this, national municipal issuance was down 49% for the first four months of 2011 compared with the same period in 2010. The tight supply situation was further compounded for

these Funds by the continued decline in issuance of AAA rated insured bonds. Over the six-month period, new insured paper accounted for approximately 6% to 10% of national issuance, compared with recent historical levels of approximately 50%.
 
In this environment of constrained tax-exempt municipal bond issuance, our primary focus was on value, quality and maturity. Due to changes to their investment policies in May 2010, these six Funds may now invest up to 20% of their managed assets in uninsured investment-grade credits rated BBB- or higher. Although we did purchase high-quality uninsured bonds during this period, with an emphasis on credits carrying strong AA ratings, we also found attractive opportunities to buy insured bonds despite the limit of insured supply. The Funds also focused on purchasing longer bonds in order to take advantage of attractive yields at the longer end of the municipal yield curve. In addition, the purchase of longer bonds provided protection for the Funds’ duration and yield curve positioning.
 
We continued to take a bottom-up approach to discovering undervalued sectors and individual credits with the potential to perform well over the long term. During this period, we found value in essential services sectors such as health care, transportation (specifically toll roads and airports), school districts, and general obligation and other tax-supported bonds issued by state and local governments for infrastructure projects. The Funds also purchased higher education credits, including those issued for higher quality private universities such as Cornell. During the last months of 2010, some of this investment activity resulted from opportunities created by the provisions of the BAB program. For example, tax-exempt supply was more plentiful in the health care and higher education sectors because, as 501(c)(3) (nonprofit) organizations, hospitals and private universities generally did not qualify for the BAB program and continued to issue bonds in the tax-exempt municipal market. In addition, bonds with proceeds earmarked for refundings, working capital and private activities were not covered by the BAB program, and this resulted in attractive opportunities in other sectors of the market, such as airports.
 
Cash for new purchases during this period was generated primarily by the proceeds from bond calls and maturing bonds, which we worked to redeploy to keep the Funds as fully invested as possible. In addition, due to extremely low short-term interest rates, NQI and NPX liquidated all of their positions in short-term floating rate securities and reinvested the proceeds in areas of the market that we believed offered better opportunities, primarily health care and higher education bonds with longer maturities.
 
As of April 30, 2011, all six of these Funds continued to use inverse floating rate securities. We employ inverse floaters as a form of leverage for a variety of reasons, including duration management, income enhancement and total return enhancement.

For the six months ended April 30, 2011, the cumulative returns on common share net asset value (NAV) for these six Funds underperformed the return for the Standard & Poor’s (S&P) National Insured Municipal Bond Index. For the same period, NVG and NEA exceeded the average return for the Lipper Insured Municipal Debt Funds Average, NPX performed in line with this benchmark, and NQI, NIO and NIF trailed the Lipper average.
 
Key management factors that influenced the Funds’ returns during this period included duration and yield curve positioning, credit exposure and sector allocation. In addition, our liquidation of NQI and NPX’s positions in floating rate securities benefited these two Funds through our reinvestment of these proceeds in higher yielding bonds. The use of leverage also had an impact on the Funds’ performance. Leverage is discussed in more detail on page eight.
 
During this period, municipal bonds with shorter maturities generally outperformed other maturity categories, with credits at the longest end of the yield curve posting the weakest returns. The underperformance of longer bonds was due in part to the rise in municipal yields at the longer end of the curve. Among these six Funds, NVG and NEA were the most advantageously situated in terms of duration and yield curve positioning, with more exposure to the outperforming shorter end of the yield curve. The other four Funds had longer durations, and their greater exposure to the underperforming long part of the curve detracted from their performance for this period. Overall, variations in duration and yield curve positioning among the Funds accounted for the majority of the differences in performance.
 
Credit exposure also played an important role in performance. During the market reversal of late 2010, as the redemption activity in municipal bond funds and, especially, high-yield funds increased, lower-rated credits were negatively impacted. For the period as a whole, bonds rated BBB generally underperformed those rated AAA. As insured Funds, all of these Funds had large weightings in the insured and higher credit quality sectors, with NVG having the greatest exposure to AAA rated bonds and NQI having the smallest AAA exposure as of April 30, 2011.

Holdings that generally helped the Funds’ returns included housing, resource recovery, and general obligation and other tax-supported bonds. In general, these Funds had relatively light exposures to housing, which limited their participation in the performance of this sector. During this period, pre-refunded bonds, which are often backed by U.S. Treasury securities, also were among the strongest performers, primarily due to their shorter effective maturities and higher credit quality. As of April 30, 2011, NVG and NEA had the largest exposures to pre-refunded bonds, while NQI and NPX had the smallest allocations. In contrast, the industrial development revenue, health care and transportation sectors turned in relatively weaker performance. NEA and NQI, in particular, had heavier weightings in the health care sector, which hampered their performance.
 
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. This is what happened in these Funds during the period, as the use of structural leverage hurt their overall performance.
 
RECENT DEVELOPMENTS REGARDING THE FUNDS’ REDEMPTION OF AUCTION RATE PREFERRED SHARES
 
Shortly after their respective inceptions, each of the Funds issued auction rate preferred shares (ARPS) to create structural leverage. As noted in past shareholder reports, the ARPS issued by many closed-end funds, including these Funds, have been hampered by a lack of liquidity since February 2008. Since that time, more ARPS have been submitted for sale in each of their regularly scheduled auctions than there have been offers to buy. In fact, offers to buy have been almost completely nonexistent since late February 2008. This means that these auctions have “failed to clear,” and that many, or all, of the ARPS shareholders who wanted to sell their shares in these auctions were unable to do so. This lack of liquidity in ARPS did not lower the credit quality of these shares, and ARPS shareholders unable to sell their shares continued to receive distributions at the “maximum rate” applicable to failed auctions, as calculated in accordance with the pre-established terms of the ARPS. In the recent market, with short term rates at multi-generational lows, those maximum rates also have been low.
 
One continuing implication for common shareholders from the auction failures is that each Fund’s cost of leverage likely has been incrementally higher at times than it otherwise might have been had the auctions continued to be successful. As a result, each Fund’s common share earnings likely have been incrementally lower at times than they otherwise might have been.
 
As noted in past shareholder reports, the Nuveen funds’ Board of Directors/Trustees authorized several methods that can be used separately or in combination to refinance
 
  Nuveen Investments 

 
 

 
a portion of the Nuveen funds’ outstanding ARPS. Some funds have utilized tender option bonds (TOBs), also known as inverse floating rate securities, for leverage purposes. The amount of TOBs that a fund may use varies according to the composition of each fund’s portfolio. Some funds have a greater ability to use TOBs than others. Some funds have issued Variable Rate Demand Preferred (VRDP) Shares or Variable MuniFund Term Preferred (VMTP) Shares, which are a floating rate form of preferred stock with a mandatory term redemption. Some funds have issued MuniFund Term Preferred (MTP) Shares, a fixed rate form of preferred stock with a mandatory redemption period of three to five years.
 
While all these efforts have reduced the total amount of outstanding ARPS issued by the Nuveen funds, the funds cannot provide any assurance on when the remaining outstanding ARPS might be redeemed.
 
During 2010 and 2011, certain Nuveen leveraged closed-end funds (including NQI, NIO, NIF, NVG and NEA) received a demand letter from a law firm on behalf of purported holders of common shares of each such fund, alleging that Nuveen and the funds’ officers and Board of Directors/Trustees breached their fiduciary duties related to the redemption at par of the funds’ ARPS. In response, the Board established an ad hoc Demand Committee consisting of certain of its disinterested and independent Board members to investigate the claims. The Demand Committee retained independent counsel to assist it in conducting an extensive investigation. Based upon its investigation, the Demand Committee found that it was not in the best interests of each fund or its shareholders to take the actions suggested in the demand letters, and recommended that the full Board reject the demands made in the demand letters. After reviewing the findings and recommendation of the Demand Committee, the full Board of each fund unanimously adopted the Demand Committee’s recommendation.
 
Subsequently, the funds that received demand letters (including NQI, NIF, NVG and NEA) were named in a consolidated complaint as nominal defendants in a putative shareholder derivative action captioned Martin Safier, et al. v. Nuveen Asset Management, et al. that was filed in the Circuit Court of Cook County, Illinois, Chancery Division (the “Cook County Chancery Court”) on February 18, 2011 (the “Complaint”). The Complaint, filed on behalf of purported holders of each fund’s common shares, also name Nuveen Fund Advisors, Inc. as a defendant, together with current and former Officers and interested Director/Trustees of each of the funds (together with the nominal defendants, collectively, the “Defendants”). The Complaint contains the same basic allegations contained in the demand letters. The suits seek a declaration that the Defendants have breached their fiduciary duties, an order directing the Defendants not to redeem any ARPS at their liquidation value using fund assets, indeterminate monetary damages in favor of the funds and an award of plaintiffs’ costs and disbursements in pursuing the action. Nuveen Fund Advisors, Inc. believes that the Complaint is without merit, and is defending vigorously against these charges.

Regulatory Matters
 
During May 2011, Nuveen Securities, LLC entered into a settlement with the Financial Industry Regulatory Authority (FINRA) with respect to certain allegations regarding Nuveen-sponsored closed-end fund ARPS marketing brochures. As part of this settlement, Nuveen Securities, LLC neither admitted to nor denied FINRA’s allegations. Nuveen is the broker-dealer subsidiary of Nuveen Investments.
 
The settlement with FINRA concludes an investigation that followed the widespread failure of auctions for ARPS and other auction rate securities, which generally began in mid-February 2008. In the settlement, FINRA alleged that certain marketing materials provided by Nuveen Securities, LLC were false and misleading. Nuveen Securities, LLC agreed to a censure and the payment of a $3 million fine.

Common Share Dividend and
Share Price Information
 
The monthly dividends of all six Funds in this report remained stable throughout the six-month reporting period ended April 30, 2011.
 
Due to normal portfolio activity, common shareholders of the following Funds received capital gains and/or net ordinary income distributions in December 2010 as follows:
 
Fund
 
Long-Term Capital Gains
(per share)
   
Short-Term Capital Gains and/or Ordinary Income (per share)
 
NIO
        $ 0.0044  
NVG
  $ 0.0029        
 
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, 2011, 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 SHARE PRICE INFORMATION

(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.
(c)
Ratios do not reflect the effect of dividend payments to Auction Rate Preferred shareholders, where applicable; Net Investment Income ratios reflect income earned and expenses incurred on assets attributable to ARPS, VMTP shares and/or VRDP shares, where applicable.
(d)
Ratios do not reflect the effect of custodian fee credits earned on the Fund’s net cash on deposit with the custodian bank, where applicable.
(e)
The expense ratios reflect, among other things, payments to Variable MuniFund Term Preferred shareholders, Variable Rate Demand Preferred shareholders and/or the interest expense deemed to have been paid by the Fund on the floating rate certificates issued by the special purpose trusts for the self-deposited inverse floaters held by the Fund, where applicable, each as described in Footnote 1 – General Information and Significant Accounting Policies, Variable MuniFund Term Preferred Shares, Variable Rate Demand Preferred Shares and Inverse Floating Rate Securities, respectively.
(f)
For the six months ended April 30, 2011.
*
Rounds to less than $.01 per share.
**
Annualized.
***
During the fiscal year ended October 31, 2006, Insured Quality (NQI) and Insured Opportunity (NIO) received payments from the Adviser of $27,762 and $42,338, respectively, to offset losses realized on the disposal of investments purchased in violation of each Fund’s investment restrictions. This reimbursement did not have an impact on the Fund’s Total Return on Common Share Net Asset Value.

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.

(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.
(c)
Ratios do not reflect the effect of dividend payments to Auction Rate Preferred shareholders, where applicable; Net Investment Income ratios reflect income earned and expenses incurred on assets attributable to ARPS and/or MTP shares, where applicable.
(d)
After expense reimbursement from the Adviser, where applicable. Ratios do not reflect the effect of custodian fee credits earned on the Fund’s net cash on deposit with the custodian bank, where applicable. As of November 30, 2010, the Adviser is no longer reimbursing Insured Tax-Free Advantage (NEA) for any fees or expenses.
(e)
The expense ratios reflect, among other things, payments to MuniFund Term Preferred shareholders and/or the interest expense deemed to have been paid by the Fund on the floating rate certificates issued by the special purpose trusts for the self-deposited inverse floaters held by the Fund, where applicable, both as described in Footnote 1 – General Information and Significant Accounting Policies, MuniFund Term Preferred Shares and Inverse Floating Rate Securities, respectively.

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 Insured Quality Municipal Fund, Inc. (NQI), Nuveen Insured Municipal Opportunity Fund, Inc. (NIO), Nuveen Premier Insured Municipal Income Fund, Inc. (NIF), Nuveen Insured Premium Income Municipal Fund 2 (NPX), Nuveen Insured Dividend Advantage Municipal Fund (NVG) and Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) (collectively, the “Funds”). Common shares of Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) are traded on the New York Stock Exchange (“NYSE”) while Common shares of Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (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.
 
Effective January 1, 2011, the Funds’ adviser, Nuveen Asset Management, a wholly-owned subsidiary of Nuveen Investments, Inc. (“Nuveen”), changed its name to Nuveen Fund Advisors, Inc. (the “Adviser”). Concurrently, the Adviser formed a wholly-owned subsidiary, Nuveen Asset Management, LLC (the “Sub-Adviser”), to house its portfolio management capabilities and to serve as the Funds’ sub-adviser, and the Funds’ portfolio managers became employees of the Sub-Adviser. This allocation of responsibilities between the Adviser and the Sub-Adviser affects each of the Funds. The Adviser will compensate the Sub-Adviser for the portfolio management services it provides to the Funds from each Fund’s management fee.
 
Each Fund seeks to provide current income exempt from regular federal income tax, and in the case of Insured Tax-Free Advantage (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.
 
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
Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1 for fair value measurement purposes. Securities primarily traded on the NASDAQ National Market (“NASDAQ”) are valued, except as indicated below, at the NASDAQ Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or NASDAQ for which there were no transactions on a given day or securities not listed on a securities exchange or NASDAQ are valued at the quoted bid price.
 
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. When price quotes are not readily available (which is usually the case for municipal bonds) 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.
 
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, 2011, Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) had outstanding when-issued/delayed delivery purchase commitments of $859,188, $1,229,988, $368,996 and $2,577,564, respectively. There were no such outstanding purchase commitments in any of the other Funds.
 
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.
 
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. 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 Insured Tax-Free Advantage (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.
 
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”). The following Funds have issued and outstanding ARPS, $25,000 stated value per share, which approximates market value, as a means of effecting financial leverage. Each Fund’s ARPS are issued in more than one Series. The dividend rate paid by the Funds on each Series is determined every seven days, pursuant to a dutch auction process overseen by the auction agent, and is payable at the end of each rate period. As of April 30, 2011, the number of ARPS outstanding, by Series and in total, for each Fund is as follows:

Beginning in February 2008, more shares for sale were submitted in the regularly scheduled auctions for the ARPS issued by the Funds than there were offers to buy. This meant that these auctions “failed to clear,’’ and that many ARPS shareholders who wanted to sell their shares in these auctions were unable to do so. ARPS shareholders unable to sell their shares received distributions at the “maximum rate’’ applicable to failed auctions as calculated in accordance with the pre-established terms of the ARPS. As of April 30, 2011, the aggregate amount of outstanding ARPS redeemed by each Fund is as follows:

During the fiscal year ended October 31, 2010, lawsuits pursuing claims made in a demand letter alleging that Insured Quality (NQI), Premier Insured Income (NIF), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage’s (NEA) Board of Directors/Trustees breached their fiduciary duties related to the redemption at par of their ARPS had been filed on behalf of shareholders of Insured Quality (NQI), Premier Insured Income (NIF), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA), against the Adviser together with current and former officers and interested director/trustees of Insured Quality (NQI), Premier Insured Income (NIF), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA). Nuveen and the other named defendants believe these lawsuits to be without merit, and all named parties intend to defend themselves vigorously. Insured Quality (NQI), Premier Insured Income (NIF), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) believe that these lawsuits will not have a material effect on them or on the Adviser’s ability to serve as investment adviser to them.
 
MuniFund Term Preferred Shares
The following Funds have issued and outstanding MuniFund Term Preferred (“MTP”) Shares, with a $10 stated value per share. Proceeds from the issuance of MTP Shares, net of offering expenses, were used to redeem a portion of each Fund’s outstanding ARPS. Each Fund’s MTP Shares are issued in one Series. Dividends, 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, 2011, the number of MTP Shares outstanding, annual interest rate and the NYSE “ticker” symbol for each Fund are as follows:

Variable Rate MuniFund Term Preferred Shares
Insured Quality (NQI) has issued and outstanding $240,400,000 Series 2014 Variable Rate MuniFund Term Preferred (“VMTP”) Shares, with $100,000 liquidation value per share. Insured Quality (NQI) issued its VMTP Shares in a privately negotiated offering in February 2011. Proceeds from the issuance of VMTP Shares, net of offering expenses, were used to redeem all of the Fund’s outstanding ARPS. The VMTP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.
 
The Fund is obligated to redeem its VMTP Shares on March 1, 2014, 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 the Fund, subject to payment of a premium until February 29, 2012, and at par thereafter. The 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.
 
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.
 
The average liquidation value outstanding and average annualized dividend rate of VMTP Shares for the Fund during the period February 24, 2011 (issuance date of shares) through April 30, 2011 were $240,400,000 and 1.50%, respectively.
 
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. Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) issued their VRDP Shares in privately negotiated offerings during December 2010, December 2010 and August 2008, respectively. Concurrent with renewing agreements with the liquidity provider for its VRDP Shares in June 2010, Insured Premium Income 2 (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

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 the Fund. The 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.

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, which is recognized as “Liquidity 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, 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 are covered by insurance guaranteeing the timely payment of principal and interest. In addition, the municipal securities in which each Fund invests will be investment grade at the time of purchase (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.
 
Each insured municipal security is covered by Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance. Assuming that the insurer remains creditworthy, the insurance feature of a municipal security guarantees the full payment of principal and interest when due through the life of an insured obligation. Such insurance does not guarantee the market value of the insured obligation or the value of the Fund’s Common shares. Original Issue Insurance and Secondary Market Insurance remain in effect as long as the municipal securities covered thereby remain outstanding and the insurer remains in business, regardless of whether the Funds ultimately dispose of such municipal securities. Consequently, the market value of the municipal securities covered by Original Issue Insurance or Secondary Market Insurance may reflect value attributable to the insurance. Portfolio Insurance, in contrast, is effective only while the municipal securities are held by the Funds and is reflected as an expense over the term of the policy, when applicable. Accordingly, neither the prices used in determining the market value of the underlying municipal securities nor the Common share
 
98
 
Nuveen Investments

 
 

 
 
net asset value of the Funds include value, if any, attributable to the Portfolio Insurance. Each policy of the Portfolio Insurance does, however, give the Funds the right to obtain permanent insurance with respect to the municipal security covered by the Portfolio Insurance policy at the time of its sale.
 
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 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, 2011, 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, 2011, each Fund’s maximum exposure to externally-deposited Recourse Trusts, is as follows:

Derivative Financial Instruments
Each Fund is authorized to invest in certain derivative instruments, including foreign currency forwards, futures, options and swap contracts. Although each Fund is authorized to invest in such derivative instruments, and may do so in the future, they did not make any such investments during the six months ended April 30, 2011.

Notes to
   
Financial Statements (Unaudited) (continued)
 
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 predetermined 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 Insured Quality (NQI) in connection with its offering of VMTP Shares ($1,120,000) were recorded as a deferred charge and will be amortized over the life of the shares. Costs incurred by Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) in connection with their offerings of VRDP Shares ($2,645,000, $755,000 and $2,535,000, respectively) were recorded as a deferred charge and will be amortized over the life of the shares. Costs incurred by Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) in connection with their offerings of MTP Shares ($1,875,000 and $1,605,000, respectively) were recorded as deferred charges and will be 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.
 
2. 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 of 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
 
100
 
Nuveen Investments

 
 

 
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).
 
The inputs or methodologies used for valuing securities are not an indication of the risk associated with investing in those securities. The following is a summary of each Fund’s fair value measurements as of April 30, 2011:

3. 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, 2011.

6. 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.
 
At April 30, 2011, the cost and unrealized appreciation (depreciation) of investments, as determined on a federal income tax basis, were as follows:

7. 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 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:
 
Average Daily Managed Assets*

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, 2011, the complex-level fee rate for these Funds was .1785%.
 
The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser has entered into Sub-Advisory Agreements with the Sub-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 Insured 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:

8. New Accounting Pronouncement
 
Fair Value Measurements and Disclosures
On May 12, 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standard Update (“ASU”) 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 by the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, the ASU requires reporting entities to disclose i) the amounts of any transfers between Level 1 and Level 2, and the reasons for the transfers, ii) for Level 3 fair value measurements, a) quantitative information about significant 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 the ASU 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 on the financial statement amounts and footnote disclosures, if any.
 
9. Subsequent Events
 
Regulatory Matters
Subsequent to the reporting period, Nuveen Securities, LLC (“Nuveen Securities”) entered into a settlement with the Financial Industry Regulatory Authority (“FINRA”) with respect to certain allegations regarding Nuveen-sponsored closed-end fund ARPS marketing brochures. As part of this settlement, Nuveen Securities neither admitted to nor denied FINRA’s allegations. Nuveen Securities is the broker-dealer subsidiary of Nuveen.
 
The settlement with FINRA concludes an investigation that followed the widespread failure of auctions for ARPS and other auction rate securities, which generally began in mid-February 2008. In the settlement, FINRA alleged that certain marketing materials provided by Nuveen Securities were false and misleading. Nuveen Securities agreed to a censure and the payment of a $3 million fine.

At a meeting held on May 25-26, 2010 (the “May Meeting”), the Boards of Trustees or Directors (as the case may be) (each, a “Board” and each Trustee or Director, a “Board Member”) of the Funds, including a majority of the Board Members who are not parties to the advisory agreements or “interested persons” of any parties (the “Independent Board Members”), considered and approved the advisory agreements (each, an “Advisory Agreement”) between each Fund and Nuveen Asset Management (the “Adviser”). Since the May Meeting, Nuveen has engaged in an internal restructuring (the “Restructuring”) pursuant to which the portfolio management services provided by the Adviser to the Funds were transferred to Nuveen Asset Management, LLC (“NAM LLC”), a newly-organized wholly-owned subsidiary of the Adviser and the Adviser changed its name to Nuveen Fund Advisors, Inc. (“NFA”). The Adviser, under its new name NFA, continues to serve as investment adviser to the Funds and, in that capacity, will continue to provide various oversight, administrative, compliance and other services. To effectuate the foregoing, NFA entered into sub-advisory agreements with NAM LLC on behalf of the Funds (each, a “Sub-Advisory Agreement”). Under each Sub-Advisory Agreement, NAM LLC, subject to the oversight of NFA and the Board, will furnish an investment program, make investment decisions for, and place all orders for the purchase and sale of securities for the portion of the respective Fund’s investment portfolio allocated to it by NFA. There have been no changes to the advisory fees paid by the Funds; rather, NFA will pay a portion of the investment advisory fee it receives to NAM LLC for its sub-advisory services. The Independent Board Members reviewed the allocation of fees between NFA and NAM LLC. NFA and NAM LLC do not anticipate any reduction in the nature or level of services provided to the Funds following the Restructuring. The personnel of NFA who engaged in portfolio management activities prior to the spinoff of NAM LLC are not expected to materially change as a result of the spinoff. In light of the foregoing, at a meeting held on November 16-18, 2010, the Board Members, including a majority of the Independent Board Members, approved the Sub-Advisory Agreements on behalf of the Funds. Given that the Restructuring was not expected to reduce the level or nature of services provided and the advisory fees paid by the Funds were the same, the factors considered and determinations made at the May Meeting in approving the Advisory Agreements were equally applicable to the approval of the Sub-Advisory Agreements. For a discussion of these considerations, please see the shareholder report of the Funds that was first issued after the May Meeting for the period including May 2010.

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

Reinvest Automatically

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.
   
Inverse Floaters: Inverse floating rate securities, also known as inverse floaters, 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.

Glossary of Terms
Used in this Report (continued)
 
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.
   
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): A Fund’s NAV per common share is calculated by subtracting the liabilities of the Fund (including any Preferred shares issued in order to leverage the Fund) from its total assets and then dividing the remainder by the number of common shares outstanding. Fund NAVs are calculated at the end of each business day.
   
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.
   
Structural Leverage: Structural Leverage consists of preferred shares or debt issued by the fund. Both of these are part of a fund’s capital structure. Structural leverage is sometimes referred to as “‘40 Act Leverage” and is subject to asset coverage limits set in the Investment Company Act of 1940.
   
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.
   
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.
