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

Portfolio Managers’ Comments
 
Nuveen Premium Income Municipal Fund, Inc. (NPI)
Nuveen Premium Income Municipal Fund 2, Inc. (NPM)
Nuveen Premium Income Municipal Fund 4, Inc. (NPT)
 
Portfolio managers Paul Brennan and Chris Drahn discuss key investment strategies and the six-month performance of these three national Funds. Paul has managed NPI and NPM since 2006 and Chris assumed portfolio management responsibility for NPT in January 2011.
 
What key strategies were used to manage these Funds during the six-month reporting period ended April 30, 2013?
 
In an environment characterized by tight supply, strong demand and lower yields, we continued to take a bottom-up approach to discovering sectors that appeared undervalued as well as individual credits that had the potential to perform well over the long term. However, the municipal market also encountered some additional volatility generated by the political environment, particularly the “fiscal cliff” at the end of 2012 and the approach of federal tax season. On the revenue side, state tax collections have grown for eleven straight quarters, exceeding pre-recession levels beginning in September 2011, while on the expense side, the states made headway in cutting and controlling costs. The current low level of municipal issuance reflects the current political distaste for additional borrowing by state and local governments facing fiscal constraints and the prevalent atmosphere of municipal budget austerity. During this period, we continued to see municipal yields remain relatively low. Borrowers seeking to take advantage of the low rate environment sparked an increase in refunding activity, with approximately 50% of municipal paper issued by borrowers that were calling existing debt and refinancing at lower rates.
 
During this period, all three Funds found value in health care, transportation, infrastructure and broad based essential services bonds backed by taxes or other revenues. In NPT, we added dedicated tax bonds secured by governmental tax or fee revenues such as sales, excise or gas taxes. Also in NPT, we added exposure to prepaid gas debt, a category of bond issuance that rallied during the period. These securities are used by municipalities to prepay natural gas costs and control energy spending.
 
In general during this period, we emphasized bonds with longer maturities. This enabled us to take advantage of more attractive yields at the longer end of the municipal yield curve and also provided some protection for the Funds’ duration and yield curve positioning. In NPI and NPM, we also purchased lower rated bonds when we

found attractive opportunities, as we believed these bonds continued to offer relative value. In NPT, our purchases were diversified across bonds with ratings ranging from AA to BBB- ratings. Our opportunities in these areas were somewhat constrained by the structure of bonds typically issued as part of refinancing deals, which tend to be characterized by shorter maturities and higher credit quality.
 
As of April 30, 2013, all three 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.
 
How did the Funds perform during the six-month reporting period ended April 30, 2013?
 
The tables in each Fund’s Performance Overview and Holding Summaries section of this report provide total returns for the Funds for the six-month, one-year, five-year and ten-year periods ended April 30, 2013. Each Fund’s total returns are compared with the performance of a corresponding market index and Lipper classification average.
 
For the six-months ended April 30, 2013, the total returns on common share net asset value (NAV) for all three of these Nuveen Funds exceeded the return for the S&P Municipal Bond Index. For this same period, the NPI and NPT performed in line with the Lipper General & Insured Leveraged Municipal Debt Funds Classification Average, while NPM lagged 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 and credit exposure. While sector allocation positively impacted NPI and NPM, it had a more neutral impact on NPT. In addition, the use of regulatory leverage was an important positive factor affecting the Funds’ performance over this period. Leverage is discussed in more detail later in this report.
 
Municipal bonds with longer maturities generally outperformed those with shorter maturities during this period. Overall, credits at the longest end of the municipal yield curve posted the strongest returns, while bonds at the shortest end produced the weakest results. For this period, duration and yield curve positioning was a major positive contributor to the performance of these Funds, with the net impact varying according to each Fund’s individual weightings along the yield curve. In particular, the Funds benefited from their holdings of long duration bonds, many of which had zero percent coupons, which generally outperformed the market during this period. NPI’s shorter duration detracted from its performance for the period.

Credit exposure was another important factor in the Funds’ performance during this six-month reporting period as lower quality bonds generally outperformed higher quality bonds. This outperformance was due in part to the greater demand for lower rated bonds as investors looked for investment vehicles offering higher yields. As investors became more comfortable taking on additional investment risk, credit spreads, or the difference in yield spreads between U.S. Treasury securities and comparable investments such as municipal bonds, narrowed through a variety of rating categories. As a result of this spread compression, these Funds benefited from their holdings of lower rated credits, especially NPT, which was overweight in BBB and A rated bonds. NPM, on the other hand, had the smallest weighting of BBB-rated bonds, which detracted from its performance.
 
During this period, revenue bonds as a whole outperformed the general municipal market. Holdings that generally made positive contributions to the Funds’ return included industrial development revenue (IDR) credits, health care (together with hospitals), transportation and housing bonds. In particular, the Funds’ health care exposure was positive for performance. Tobacco credits backed by the 1998 master tobacco settlement agreement also were one of the top performing market sectors, helped by their longer effective durations and the increased demand for higher yielding investments by investors who had become less risk-averse. In addition, based on recent data showing that cigarette sales had fallen less steeply than anticipated, the 46 states participating in the agreement stand to receive increased payments from the tobacco companies. As of April 30, 2013, all three Funds were slightly overweight in tobacco bonds, which benefited their performance as tobacco credits rallied.

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

Effective Leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative and other investments in a Fund’s portfolio that increase the Fund’s investment exposure. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage. Regulatory leverage consists of preferred shares issued or borrowings of a Fund. Both of these are part of a Fund’s capital structure. Regulatory leverage is sometimes referred to as “‘40 Act Leverage” and is subject to asset coverage limits set forth in the Investment Company Act of 1940.
 
THE FUNDS’ REGULATORY LEVERAGE
 
As of April 30, 2013, the Funds have issued and outstanding Variable Rate MuniFund Term Preferred (VMTP) Shares and Variable Rate Demand Preferred (VRDP) Shares as shown in the accompanying tables.

The Fund completed the exchange offer in which it refinanced its existing VMTP Shares with new VMTP Shares at a reduced cost and with a term redemption date of December 1, 2015. The proceeds from the additional VMTP Shares will be used to take advantage of opportunities in the current municipal market. Dividends on the VMTP Shares are set weekly at a fixed spread to the Securities Industry and Financial Markets Association Municipal Swap Index (SIFMA).

***
Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is based on a federal income tax rate of 28.0%. When comparing a Fund to investments that generate qualified dividend income, the Taxable-Equivalent Yield is lower.
 
All of the Funds in this report seek to pay stable dividends at rates that reflect each Fund’s past results and projected future performance. During certain periods, each Fund may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it holds the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s NAV. Conversely, if a Fund has cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Fund’s NAV. Each Fund will, over time, pay all of its net investment income as dividends to shareholders. As of April 30, 2013, all of the Funds in this report had positive UNII balances, based on our best estimate, for tax purposes and positive UNII balances for financial reporting purposes.
 
COMMON SHARE REPURCHASES
 
During November 2012, the Nuveen Funds’ Board of Directors/Trustees reauthorized the Funds’ open-market share repurchase program, allowing each Fund to repurchase an aggregate of up to approximately 10% of its outstanding common shares.

Risk Considerations
 
Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation. Past performance is no guarantee of future results. Fund common shares are subject to a variety of risks, including:
 
Investment, Market and Price Risk. An investment in common shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in common shares represents an indirect investment in the municipal securities owned by the Fund, which generally trade in the over-the-counter markets. Shares of closed-end investment companies like these Funds frequently trade at a discount to their net asset value (NAV). Your common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.
 
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.
 
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.

(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 New York Stock Exchange (“NYSE”) symbols are Nuveen Premium Income Municipal Fund, Inc. (NPI), Nuveen Premium Income Municipal Fund 2, Inc. (NPM) and Nuveen Premium Income Municipal Fund 4, Inc. (NPT) (each a “Fund” and collectively the “Funds”). The Funds are registered under the Investment Company Act of 1940, as amended, as diversified closed-end registered investment companies.
 
On December 31, 2012, the Funds’ investment adviser converted from a Delaware Corporation to a Delaware limited liability company. As a result, Nuveen Fund Advisors, Inc., a wholly-owned subsidiary of Nuveen Investments, Inc. (“Nuveen”), changed its name to Nuveen Fund Advisors, LLC (the “Adviser”). There were no changes to the identities or roles of any personnel as a result of the change.
 
Each Fund seeks to provide current income exempt from regular federal income tax by investing primarily in a portfolio of municipal obligations issued by state and local government authorities or certain U.S. territories.
 
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 and other fixed income securities are provided by a pricing service approved by the Funds’ Board of Directors. 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.
 
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 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 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 investment transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Funds have instructed the custodian to earmark securities in the Funds’ portfolios with a current value at least equal to the amount of the when-issued/delayed delivery

purchase commitments. As of April 30, 2013, Premium Income (NPI), Premium Income 2 (NPM) and Premium Income 4 (NPT) had outstanding when issued/delayed delivery purchase commitments of $5,033,347, $5,693,869 and $4,221,867, respectively.
 
Investment Income
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 on the Statement of Operations reflects a refund of workout expenditures paid in a prior reporting period, when applicable.
 
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 and designated state income taxes, 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”). During prior fiscal periods, the Funds redeemed all of their outstanding ARPS, at liquidation value.
 
Variable Rate MuniFund Term Preferred Shares
The following Fund has issued and outstanding Variable Rate MuniFund Term Preferred (“VMTP”) Shares, with a $100,000 liquidation value per share.
 
Premium Income (NPI) issued its VMTP Shares in a privately negotiated offering, which were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.
 
During the current fiscal period, Premium Income (NPI) exchanged all 4,024 shares of its outstanding Series 2014 VMTP for 4,024 shares of Series 2015 VMTP. Concurrent with the exchange, Premium Income (NPI) issued an additional $4,600,000 at liquidation value, of Series 2015 VMTP Shares through a privately negotiated offering, which were offered to qualified institutional buyers pursuant to Rule 144A under the Securities act of 1933. The Fund completed the exchange offer in which it refinanced its existing VMTP Shares with new VMTP Shares at a reduced cost and with a term redemption date of December 1, 2015.
 
As of April 30, 2013, the number of VMTP Shares outstanding, at liquidation value, for the Fund is as follows:
 
     
Premium

The 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. 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.

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 and recognized as “Variable Rate MuniFund Term Preferred (VMTP) Shares, at liquidation value” 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. Costs incurred by the Fund in connection with its offering of VMTP Shares were recorded as a deferred charge, which are amortized over the life of the shares and are recognized as components of “Deferred offering costs” on the Statement of Assets and Liabilities and “Interest expense and amortization of offering costs” on the Statement of Operations.
 
In conjunction with the Fund’s exchange of VMTP Shares, the remaining deferred offering costs of $1,153,416 for the Fund’s issuance of Series 2014 VMTP Shares were fully expensed during the current fiscal period, as the exchange was deemed and extinguishment of debt. Offering costs of $155,000 were incurred with the Fund’s issuance of Series 2015 VMTP Shares, which were recorded as a deferred charge and are being amortized over the life of the shares.
 
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. Premium Income 2 (NPM) and Premium Income 4 (NPT) issued their VRDP Shares in privately negotiated offerings. The VRDP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.
 
As of April 30, 2013, the number of VRDP Shares outstanding and maturity date for each Fund are as follows:

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. Each Fund pays an annual remarketing fee of .10% on the aggregate principal amount of all VRDP Shares outstanding. Each Fund’s VRDP Shares have successfully remarketed since issuance.
 
Dividends on 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.

For financial reporting purposes only, the liquidation value of VRDP Shares is recorded as a liability and recognized as “Variable Rate Demand Preferred (VRDP) Shares, at liquidation value” 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, when applicable. Dividends paid on VRDP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. Costs incurred by the Funds in connection with their offerings of VRDP Shares were recorded as a deferred charge, which are amortized over the life of the shares and are recognized as a component of “Deferred offering costs” on the Statement of Assets and Liabilities and “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 “Liquidity fees” and “Remarketing fees,” respectively, on the Statement of Operations.
 
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, at their liquidation value, 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, 2013, 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.
 
As of April 30, 2013, each Fund’s maximum exposure to the floating rate obligations issued by externally-deposited Recourse Trusts was as follows:

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-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. 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.
 
Indemnifications
Under the Funds’ organizational documents, their officers and directors 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 for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances.
 
The following is a summary of the three-tiered hierarchy of valuation input levels.
 
Level 1 –  
Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.
Level 2 –  
Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3 –  
Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

The Nuveen funds’ Board of Directors/Trustees is responsible for the valuation process and has delegated the oversight of the daily valuation process to the Adviser’s Valuation Committee. The Valuation Committee, pursuant to the valuation policies and procedures adopted by the Board of Directors/Trustees, is responsible for making fair value determinations, evaluating the effectiveness of the funds’ pricing policies and reporting to the Board of Directors/Trustees. The Valuation Committee is aided in its efforts by the Adviser’s dedicated Securities Valuation Team, which is responsible for administering the daily valuation process and applying fair value methodologies as approved by the Valuation Committee. When determining the reliability of independent pricing services for investments owned by the funds, the Valuation Committee, among other things, conducts due diligence reviews of the pricing services and monitors the quality of security prices received through various testing reports conducted by the Securities Valuation Team.
 
The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making a fair value determination, based on the facts and circumstances specific to the portfolio instrument. Fair value determinations generally will be derived as follows, using public or private market information:
 
 
(i.)
If available, fair value determinations shall be derived by extrapolating from recent transactions or quoted prices for identical or comparable securities.
     
 
(ii.)
If such information is not available, an analytical valuation methodology may be used based on other available information including, but not limited to: analyst appraisals, research reports, corporate action information, issuer financial statements and shelf registration statements. Such analytical valuation methodologies may include, but are not limited to: multiple of earnings, discount from market value of a similar freely-traded security, discounted cash flow analysis, book value or a multiple thereof, risk premium/yield analysis, yield to maturity and/or fundamental investment analysis.
 
The purchase price of a portfolio instrument will be used to fair value the instrument only if no other valuation methodology is available or deemed appropriate, and it is determined that the purchase price fairly reflects the instrument’s current value.
 
For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Directors/Trustees, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such testing and fair valuation occurrences are reported to the Board of Directors/Trustees.
 
3. Derivative Instruments and Hedging Activities
Each Fund is authorized to invest in certain derivative instruments, including futures, options, swap contracts and other derivatives.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. Although the Funds are authorized to invest in derivative instruments, and may do so in the future, they did not make any such investments during the six months ended April 30, 2013.
 
4. Fund Shares
Common Shares
The Funds did not repurchase any of their outstanding Common shares during the six months ended April 30, 2013 or the fiscal year ended October 31, 2012.

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.

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 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:
 
Average Daily Managed Assets*
   
Fund-Level Fee Rate
For the first $125 million
   
.4500
%
For the next $125 million

For the next $3 billion

*
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, 2013, the complex-level fee rate for each of these Funds was .1661%.
 
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 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 has adopted a deferred compensation plan for independent directors that enables directors 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.
 
8. New Accounting Pronouncements
 
Financial Accounting Standards Board (“FASB”) Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities
In January 2013, Accounting Standards Update (“ASU”) 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, replaced ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 is effective for fiscal years beginning on or after January 1, 2013. ASU 2011-11 was intended to enhance disclosure requirements on the offsetting of financial assets and liabilities. ASU 2013-01 limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. Management is currently evaluating the application of ASU 2013-01 and its impact to the financial statements and footnote disclosures, if any.

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
 
84
 
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.
   
Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond Fund’s value to changes when market interest rates change. Generally, the longer a bond’s or Fund’s duration, the more the price of the bond or Fund will change as interest rates change.
   
Effective Leverage: Effective leverage is a Fund’s effective economic leverage, and includes both regulatory leverage (see Leverage) and the leverage effects of certain derivative investments in the Fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.
   
Gross Domestic Product (GDP): The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.
   
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.
 
86
 
Nuveen Investments

 
 

 
 
Leverage: Using borrowed money to invest in securities or other assets, seeking to increase the return of an investment or portfolio.
   
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.
   
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.
   
S&P Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment-grade U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
   
Total Investment Exposure: Total investment exposure is a Fund’s assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a Fund’s use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.
   
Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.
