PRELIMINARY PROSPECTUS

1.6 Million Common Shares

Nuveen Select Tax-Free Income Portfolio

Nuveen Select Tax-Free Income Portfolio (the “Fund”) is a diversified, closed-end management investment company. The Fund’s investment objective is to provide current income exempt from regular federal income tax, consistent with preservation of capital. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its Managed Assets (as defined below under “Portfolio Contents”) in municipal securities and other related investments, the income from which is exempt from regular federal income tax and federal alternative minimum tax. Under normal circumstances, the Fund invests at least 80% of its Managed Assets in municipal securities and other related investments that at the time of investment are rated within the four highest grades by at least one of the nationally recognized statistical rating organizations (“NRSRO”) that rate such security or are unrated but judged to be of comparable quality by the Fund’s sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”). The Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by Nuveen Asset Management. No more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Asset Management. The Fund may also invest up to 20% of its Managed Assets in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals (“AMT Bonds”). In addition, the Fund intends to use leverage to seek to enhance its potential for current income exempt from regular federal income tax. The Fund cannot assure you that it will achieve its investment objective.

Investing in the Fund’s common shares involves certain risks that are described in the “Risk Factors” and “How the Fund Manages Risks” sections of this Preliminary Prospectus (“Prospectus”).

Neither the Securities and Exchange Commission (“SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

You should read this Prospectus, which contains important information about the Fund, before deciding whether to invest and retain it for future reference. A Preliminary Statement of Additional Information (“SAI”), dated April 22, 2013, containing additional information about the Fund, has been filed with the SEC and is incorporated by reference in its entirety into this Prospectus. You may request a free copy of the SAI, the table of contents of which is on the last page of this Prospectus, annual and semi-annual reports to shareholders and other information about the Fund, and make shareholder inquiries by calling (800) 257-8787, by writing to the Fund or from the Fund’s website (http://www.nuveen.com). The information contained in, or that can be accessed through, the Fund’s website is not part of this Prospectus. You also may obtain a copy of the SAI (and other information regarding the Fund) from the SEC’s web site (http://www.sec.gov).

The Fund’s common shares do not represent a deposit or obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other governmental agency.

Portfolio Contents. Under normal circumstances, the Fund will invest at least 80% of its Managed Assets (as defined below) in municipal securities, (i) the income from which is exempt from regular federal income tax and federal alternative minimum tax, as a fundamental policy, and (ii) that at the time of investment are rated investment grade quality, as a non-fundamental policy. “Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to, the portion of assets in special purpose trusts of which the Fund owns the inverse floater certificates that has been effectively financed by the trust’s issuance of floating rate certificates. A security is considered investment grade quality if it is rated within the four highest letter grades (BBB or Baa or better) by at least one of the NRSROs that rate such security, or if it is unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management. Also, as a non-fundamental policy, the Fund may

invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by Nuveen Asset Management. Additionally, as a non-fundamental policy, no more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Asset Management. Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds. As a fundamental policy, the Fund may invest up to approximately 15% of its Managed Assets in inverse floating rate securities. The Fund may invest up to 20% of its Managed Assets in AMT Bonds. The Fund cannot assure you that it will achieve its investment objective.

Leverage. The Fund intends to use leverage to seek to enhance its potential for current income exempt from regular federal income tax. The Fund intends to use leverage by investing in inverse floating rate securities that have the economic effect of leverage, or the Fund may leverage its capital structure by issuing senior securities, such as preferred shares, investing in debt securities or by borrowing. The Fund currently uses leverage by investing in inverse floating rate securities. If current market conditions change (for example, if there is a material decrease in the supply of inverse floating rate securities or if newly issued senior securities become a more attractive financing option), the Fund may leverage itself by issuing senior securities such as preferred shares, investing in debt securities, or by borrowing. There can be no assurance that the Fund’s leverage strategy will be successful.

Adviser and Sub-Adviser. Nuveen Fund Advisors, LLC, the Fund’s investment adviser, is responsible for determining the Fund’s overall investment strategies and their implementation. Nuveen Asset Management is the Fund’s investment sub-adviser and oversees the day-to-day investment operations of the Fund.

Common shares will not be sold at a price less than current net asset value plus the per share amount of the commission to be paid to Nuveen Securities, LLC (“Nuveen Securities”). The Fund and Nuveen Securities will suspend the sale of common shares if the per share price of the shares is less than the minimum price. The Fund currently intends to distribute the shares offered pursuant to this Prospectus primarily through at-the-market transactions, although from time to time it may also distribute shares through an underwriting syndicate or a privately negotiated transaction. To the extent shares are distributed other than through at-the-market transactions, the Fund will file a supplement to this Prospectus describing such transactions. For information on how common shares may be sold, see the “Plan of Distribution” section of this Prospectus.

Common shares are listed on the New York Stock Exchange (“NYSE”). The trading or “ticker” symbol of the Fund is “NXP.” The Fund’s closing price on the NYSE on April , 2013 was $ .

The date of this Prospectus is April 22, 2013

PROSPECTUS SUMMARY

This is only a summary. You should review the more detailed information contained elsewhere in this Prospectus and in the SAI.

The Fund

Nuveen Select Tax-Free Income Portfolio (the “Fund”) is a diversified, closed-end management investment company. See “The Fund.” The Fund’s Common shares, $.01 par value (“Common Shares”), are traded on the New York Stock Exchange (“NYSE”) under the symbol “NXP.” See “Description of Common Shares.” As of , 2013, the Fund had Common Shares outstanding and net assets applicable to Common Shares of $ .

Investment Objectives and Policies

The Fund’s investment objective is to provide current income exempt from regular federal income tax, consistent with preservation of capital. The Fund cannot assure you that it will achieve its investment objective. The Fund’s investment objective and any investment policies identified as such are considered fundamental and may not be changed without shareholder approval.

Under normal circumstances and as a fundamental policy, the Fund will invest at least 80% of its Managed Assets in municipal securities and other related investments, the income from which is exempt from regular federal income tax and federal alternative minimum tax. “Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to, the portion of assets in special purpose trusts of which the Fund owns the inverse floater certificates that has been effectively financed by the trust’s issuance of floating rate certificates. See “The Fund’s Investments” for additional information on the types of securities in which the Fund may invest. As a non-fundamental policy, the Fund seeks to achieve its investment objective by investing in a diversified portfolio of municipal securities at least 80% comprised of investment grade quality securities, the income from which is exempt from regular federal income tax. As a fundamental policy, the Fund may invest up to 20% of its Managed Assets in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals (“AMT Bonds”). Any investment by the Fund in AMT Bonds will not be counted towards meeting its 80% investment in municipal securities exempt from regular federal income tax and federal alternative minimum tax. As of , 2013, the Fund has invested % of its Managed Assets in AMT Bonds.

Nuveen Asset Management (defined below under “Sub-Adviser”) seeks to identify and invest in municipal securities that it believes are

underrated and undervalued, based on its bottom-up, research-driven investment strategy. Nuveen Asset Management believes its value oriented strategy offers the opportunity to construct a well-diversified portfolio of municipal securities that has the potential to outperform major municipal market benchmarks over the longer term. Underrated municipal securities are those whose credit ratings do not, in Nuveen Asset Management’s opinion, reflect their true creditworthiness. Undervalued municipal securities are securities that, in Nuveen Asset Management’s opinion, are worth more than the value assigned to them in the marketplace. A municipal security’s market value generally will depend upon its form, maturity, call features and interest rate, as well as the issuer’s credit quality or credit rating, all such factors examined in the context of the municipal securities market and interest rate levels and trends. In addition, the Fund intends to use leverage to seek to enhance its potential for current income exempt from regular federal income tax. See “Use of Leverage.”

The Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal securities that provide for the payment of interest income that is exempt from regular federal income tax (as used in this document, the term “municipal securities” refers to all such investments collectively). See “The Fund’s Investments—Municipal Securities” for additional information on the types of municipal securities in which the Fund may invest. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects, such as roads, schools, and water supply systems. Municipal securities also may be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility and pollution control projects. Municipal securities may be issued on a long-term basis to provide long-term financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments, and mortgage payments. Municipal securities also may be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms that include fixed coupon, variable rate, zero coupon, capital appreciation bonds, floating rate securities, and inverse floating rate securities. Such municipal securities also may be acquired through investments in pooled vehicles, partnerships, or other investment companies. The Fund may invest in these types of securities, including floating rate securities and inverse floating rate securities, in order to more efficiently achieve its desired overall portfolio structure as well as enhance its ability to achieve its investment objective.

The Fund also may invest in derivative instruments in pursuit of its investment objective, including inverse floating rate securities. Such instruments also include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts, or other derivative instruments. However, the Fund may not enter into futures contracts or related options or forward contracts, if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on futures contracts and related options. Nuveen Asset Management uses derivatives to seek to enhance return, to hedge some of the risks of its investments in fixed income securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income. See “The Fund’s Investments—Derivatives.”

Under normal circumstances:

•

As a non-fundamental policy, the Fund will invest at least 80% of its Managed Assets in municipal securities and other related investments that at the time of investment are investment grade quality. A security is considered investment grade quality if it is rated within the four highest letter grades (BBB or Baa or better) by at least one of the NRSROs that rate such security (even if it is rated lower by another), or if it is unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management.

•

As a non-fundamental policy, the Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management. Also, as a non-fundamental policy, no more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Asset Management. Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds. See “Risk Factors—Credit and Below Investment Grade Risk.”

•

As of , 2013, the weighted average maturity of the Fund’s portfolio was years. The Fund will generally invest in municipal securities with a weighted average maturity of at least 15 years, but it may be shortened or lengthened, depending on market conditions and on an assessment by the Fund’s portfolio manager of which segments of the municipal securities market offer the most favorable relative investment values and opportunities for tax-exempt income and total return.

•

The Fund will not invest more than 25% of its Managed Assets in municipal securities in any one industry or in any one state of origin and no more than 5% of its Managed Assets in any one issuer.

•

The Fund will not invest more than 15% of its Managed Assets in municipal securities that, at the time of investment, are illiquid (i.e., securities that are not readily marketable). See “Risk Factors—Illiquid Securities Risk.”

See “The Fund’s Investments—Investment Objective, and Investment Policies.”

As of , 2013, approximately % of the Fund’s Managed Assets were invested in securities rated investment grade by an NRSRO (including Standard & Poor’s Corporation Ratings Group, a division of The McGraw-Hill Companies, Inc. (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”)). The relative percentages of the value of the investments attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund’s assets by Nuveen Asset Management, market value fluctuations, issuance of additional shares and other events.

During temporary defensive periods or in order to keep the Fund’s cash fully invested, including during the period when the net proceeds of the offering of Common Shares are being invested, the Fund may deviate from its investment policies and objectives. During such periods, the Fund may invest up to 100% of its Managed Assets in short-term investments, including high quality, short-term securities that may be either tax-exempt or taxable. The Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Investment in taxable short-term investments would result in a portion of your dividends being subject to regular federal income tax, and if the proportion of taxable investments exceeded 50% of the Fund’s total assets as of the close of any quarter of the Fund’s taxable year, the Fund would not satisfy the general eligibility test that would permit it to pay exempt-interest dividends for that taxable year. Such transactions will be used solely to reduce risk. There can be no assurance that such strategies will be successful. For a more complete discussion of the Fund’s portfolio composition, see “The Fund’s Investments.”

“Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating effective leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to, the portion of assets in special purpose trusts of which the Fund owns the inverse floater certificates that has been effectively financed by the trust’s issuance of floating rate certificates. See “The Fund’s Investments—Inverse Floating Rate Securities.”

Investment Adviser

Nuveen Fund Advisors, LLC (“NFALLC”), the Fund’s investment adviser, is responsible for determining the Fund’s overall strategy and its implementation. NFALLC, a registered investment adviser, is a wholly-owned subsidiary of Nuveen Investments, Inc. (“Nuveen Investments”). Founded in 1898, Nuveen Investments and its affiliates had approximately $219 billion of assets under management as of December 31, 2012. See “Management of the Fund—Investment Adviser, Sub-Adviser and Portfolio Manager.”

Sub-Adviser

Nuveen Asset Management, LLC (“Nuveen Asset Management”) serves as the Fund’s sub-adviser and is a wholly-owned subsidiary of NFALLC. Nuveen Asset Management is a registered investment adviser. Nuveen Asset Management oversees the day-to-day investment operations of the Fund.

Nuveen Securities, LLC (“Nuveen Securities”), a registered broker-dealer affiliate of NFALLC and Nuveen Asset Management, is involved in the offering of the Fund’s Common Shares. See “Plan of Distribution-Distribution Through At-the-Market Transactions.”

Use of Leverage

Financial leverage is created as a result of the Fund’s investments in residual interest certificates of tender option bond trusts, also called inverse floating rate securities, because the Fund’s investment exposure to the underlying bonds held by the trust have been effectively financed by the trust’s issuance of floating rate certificates. If current market conditions change (for example, if there is a material decrease in the supply of inverse floating rate securities or if newly issued senior securities become a more attractive financing option), the Fund may use other forms of leverage. As of , 2013, the Fund’s total effective leverage was approximately % of its Managed Assets.

Leverage involves special risks. See “Risk Factors—Leverage Risk.” There is no assurance that the Fund’s leveraging strategy will be successful. Interest on borrowings may be at a fixed or floating rate, but generally will be based on short-term rates. The Fund will seek to

invest the proceeds of any future financial leverage in a manner consistent with the Fund’s investment objective and policies. See “Use of Leverage.”

The Fund pays a management fee to NFALLC (which in turn pays a portion of its fee to the Fund’s sub-adviser, Nuveen Asset Management) based on a percentage of Managed Assets. Managed Assets include the proceeds realized and managed from the Fund’s use of leverage as set forth in the Fund’s investment management agreement. NFALLC will be responsible for using leverage to pursue the Fund’s investment objective and will base its decision regarding whether and how much leverage to use for the Fund based on its assessment of whether such use of leverage will advance the Fund’s investment objective. However, the fact that a decision to increase the Fund’s leverage will have the effect, all other things being equal, of increasing Managed Assets and therefore NFALLC and Nuveen Asset Management’s fees means that NFALLC and Nuveen Asset Management may have a conflict of interest in determining whether to increase the Fund’s use of leverage. NFALLC will seek to manage that potential conflict by only increasing the Fund’s use of leverage when it determines that such increase is consistent with the Fund’s investment objective, and by periodically reviewing the Fund’s performance and use of leverage with the Board.

Offering Methods

The Fund may offer shares using one or more of the following methods: (i) at-the-market transactions through one or more broker-dealers that have entered into a selected dealer agreement with Nuveen Securities, one of the Fund’s underwriters; (ii) through an underwriting syndicate; and (iii) through privately negotiated transactions between the Fund and specific investors. See “Plan of Distribution.”

Distribution Through At-the-Market Transactions. The Fund from time to time may offer its Common Shares through Nuveen Securities, to certain broker-dealers that have entered into selected dealer agreements with Nuveen Securities. Currently, Nuveen Securities has entered into a selected dealer agreement with UBS Securities LLC (“UBS”) pursuant to which UBS will be acting as Nuveen Securities’ sub-placement agent with respect to at-the-market offerings of Common Shares. Common Shares will only be sold on such days as shall be agreed to by the Fund and Nuveen Securities. Common Shares will be sold at market prices, which shall be determined with reference to trades on the NYSE, subject to a minimum price to be established each day by the Fund. The minimum price on any day will not be less than the current net asset value per share plus the per share amount of the commission to be paid to Nuveen Securities. The Fund and Nuveen Securities will suspend the sale of Common Shares if the per share price of the shares is less than the minimum price.

The Fund will compensate Nuveen Securities with respect to sales of the Common Shares at a commission rate of 1.0% of the gross proceeds of the sale of Common Shares. Nuveen Securities will compensate broker-dealers participating in the offering at a fixed rate of 0.8% of the gross sales proceeds of the sale of Common Shares sold by that broker-dealer. Settlements of Common Share sales will occur on the third business day following the date of sale.

In connection with the sale of the Common Shares on behalf of the Fund, Nuveen Securities may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended (the “1933 Act”), and the compensation of Nuveen Securities may be deemed to be underwriting commissions or discounts. Unless otherwise indicated in a further Prospectus supplement, Nuveen Securities will act as underwriter on a reasonable efforts basis.

The offering of Common Shares pursuant to the Distribution Agreement will terminate upon the earlier of (i) the sale of all Shares subject thereto or (ii) termination of the Distribution Agreement. The Fund and Nuveen Securities each have the right to terminate the Distribution Agreement in its discretion at any time. See “Plan of Distribution—Distribution Through At-The-Market Transactions.”

The Fund currently intends to distribute the shares offered pursuant to this Prospectus primarily through at-the-market transactions, although from time to time it may also distribute shares through an underwriting syndicate or a privately negotiated transaction. To the extent shares are distributed other than through at-the-market transactions, the Fund will file a supplement to this Prospectus describing such transactions.

The Fund’s closing price on the NYSE on April , 2013 was $ .

UBS, its affiliates and their respective employees hold or may hold in the future, directly or indirectly, investment interests in Nuveen Investments, Inc. and its funds. The interests held by employees of UBS or its affiliates are not attributable to, and no investment discretion is held by, UBS or its affiliates. Common Shares, Underwriters will market and price the offering on an expedited basis (e.g., overnight or similarly abbreviated offering period). The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities and the underwriting syndicate.

Distribution Through Underwriting Syndicates. The Fund from time to time may issue additional Common Shares through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s Common Shares, underwriters will market and price the offering on an expedited basis (e.g., overnight or similarly abbreviated offering period). The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities and the underwriting syndicate.

The Fund will offer its shares at a price equal to a specified discount of up to 5% from the closing market price of the Fund’s Common Shares on the day prior to the offering date. The applicable discount will be negotiated by the Fund and Nuveen Securities in consultation with the underwriting syndicate on a transaction-by-transaction basis. The Fund will compensate the underwriting syndicate out of the proceeds of the offering based upon a sales load of up to 4% of the gross proceeds of the sale of Common Shares. The minimum net proceeds per share to the Fund will not be less than the greater of (i) the Fund’s latest net asset value per Common Share or (ii) 91% of the closing market price of the Fund’s Common Shares on the day prior to the offering date. See “Plan of Distribution—Distribution Through Underwriting Syndicates.”

Distribution Through Privately Negotiated Transactions. The Fund, through Nuveen Securities, from time to time may sell directly to, and solicit offers from, institutional and other sophisticated investors, who may be deemed to be underwriters as defined in the 1933 Act for any resale of Common Shares.

The terms of such privately negotiated transactions will be subject to the discretion of the management of the Fund. In determining whether to sell Common Shares through a privately negotiated transaction, the Fund will consider relevant factors including, but not limited to, the attractiveness of obtaining additional funds through the sale of Common Shares, the purchase price to apply to any such sale of Common Shares and the investor seeking to purchase the Common Shares.

Common Shares issued by the Fund through privately negotiated transactions will be issued at a price equal to the greater of (i) the net asset value per Common Share of the Fund’s Common Shares or (ii) at a discount ranging from 0% to 5% of the average daily closing market price of the Fund’s Common Shares at the close of business on the two business days preceding the date upon which Common Shares are sold pursuant to the privately negotiated transaction. The applicable discount will be determined by the Fund on a transaction-by-transaction basis. See “Plan of Distribution—Distribution Through Privately Negotiated Transactions.”

Special Risk Considerations

Investment in the Fund involves special risk considerations, which are summarized below. The Fund is designed as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program. See “Risk Factors” for a more complete discussion of the special risk considerations of an investment in the Fund.

Investment and Market Risk. An investment in the Fund’s Common Shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Common Shares represents an indirect investment in the municipal securities

owned by the Fund, which generally trade in the over-the-counter markets. Your Common Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions. See “Risk Factors—Investment and Market Risk.”

Market Discount from Net Asset Value. Shares of closed-end investment companies like the Fund have during some periods traded at prices lower than net asset value. The Fund cannot predict whether Common Shares will trade at, above or below net asset value. This characteristic is a risk separate and distinct from the risk that the Fund’s net asset value could decrease as a result of investment activities. Investors bear a risk of loss to the extent that the price at which they sell their shares is lower in relation to the Fund’s net asset value than at the time of purchase, assuming a stable net asset value. Proceeds from the sale of Common Shares in this offering will be reduced by shareholder transaction costs (if applicable, which vary depending on the offering method used). Depending on the premium of the Common Shares at the time of any offering of Common Shares hereunder, the Fund’s net asset value may be reduced by an amount up to the offering costs borne by the Fund (estimated to be an additional % of the offering price assuming a Common Share offering price of $ (the Fund’s closing price on the NYSE on April , 2013)).

The net asset value per Common Share will also be reduced by costs associated with any future issuances of Common or preferred shares. The Common Shares are designed primarily for long-term investors, and you should not view the Fund as a vehicle for trading purposes. See “Risk Factors—Market Discount from Net Asset Value.”

Credit and Below Investment Grade Risk. Credit risk is the risk that one or more municipal securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. The Fund may invest up to 20% (measured at the time of investment) of its Managed Assets in municipal securities that are rated below investment grade or that are unrated but judged to be of comparable quality by Nuveen Asset Management. If a municipal security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, Nuveen Asset Management will consider what action, including the sale of the security, is in the best interests of the Fund and its shareholders. This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities). Municipal securities of below investment grade quality are predominately

speculative with respect to the issuer’s capacity to pay interest and repay principal when due, and are susceptible to default or decline in market value due to adverse economic and business developments, and are commonly referred to as junk bonds. Also, to the extent that the rating assigned to a municipal security in the Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for municipal securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade municipal securities. For these reasons, an investment in the Fund compared with a portfolio consisting solely of investment grade securities, may experience the following:

•

increased price sensitivity resulting from changing interest rates and/or a deteriorating economic environment;

•

greater risk of loss due to default or declining credit quality;

•

adverse issuer specific events that are more likely to render the issuer unable to make interest and/or principal payments; and

•

the possibility that a negative perception of the below investment grade market develops, resulting in the price and liquidity of below investment grade securities becoming depressed, and this negative perception could last for a significant period of time.

See “Risk Factors—Credit and Below Investment Grade Risk.”

Interest Rate Risk. Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in the Fund’s portfolio will decline in value because of increases in market interest rates. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. Currently, market interest rates are at or near historical lows. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change. Because the Fund will invest primarily in long-term municipal securities, the Common Share net asset value and market price per share will fluctuate more in response to changes in market interest rates than if the Fund invested primarily in shorter-term municipal securities. Because the values of lower-rated and comparable unrated debt securities are affected both by credit risk and interest rate risk, the price movements of such lower grade securities in response to changes in interest rates typically have not been highly correlated to the fluctuations of the prices of investment grade quality securities in response to changes in market interest rates. The Fund’s use of leverage, as described herein, will tend to increase Common Share interest rate risk. See “Risk Factors—Interest Rate Risk.”

Economic and Political Events Risk. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds). Such developments may adversely affect a specific industry or local political and economic conditions, and thus may lead to declines in the bonds’ creditworthiness and value.

Municipal Securities Market Risk. The amount of public information available about the municipal securities in the Fund’s portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of Nuveen Asset Management than if the Fund were a stock fund or taxable bond fund. The secondary market for municipal securities, particularly the below investment grade bonds in which the Fund may invest, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its bonds at attractive prices. See “Risk Factors—Municipal Securities Market Risk” and “Risk Factors—Special Risks Related to Certain Municipal Obligations.”

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Common Share’s market price or your overall returns. See “Risk Factors—Reinvestment Risk.”

Tax Risk. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, among other things, the Fund must derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy a diversification test on a quarterly basis. If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions were not available to the Fund and it were to fail to qualify for treatment as a regulated investment company for a taxable year, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates without any

deduction for distributions to stockholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

To qualify to pay exempt-interest dividends, which are treated as items of interest excludable from gross income for federal income tax purposes, at least 50% of the value of the total assets of the Fund must consist of obligations exempt from regular income tax as of the close of each quarter of the Fund’s taxable year. If the proportion of taxable investments held by the Fund exceeds 50% of the Fund’s total assets as of the close of any quarter of any Fund taxable year, the Fund will not satisfy for that taxable year the general eligibility test that otherwise permits it to pay exempt-interest dividends for the taxable year.

The value of the Fund’s investments and its net asset value may be adversely affected by changes in tax rates and policies. Because interest income from municipal securities is normally not subject to regular federal income taxation, the attractiveness of municipal securities in relation to other investment alternatives is affected by changes in federal income tax rates or changes in the tax-exempt status of interest income from municipal securities. Any proposed or actual changes in such rates or exempt status, therefore, can significantly affect the demand for and supply, liquidity and marketability of municipal securities. This could in turn affect the Fund’s net asset value and ability to acquire and dispose of municipal securities at desirable yield and price levels. Additionally, the Fund is not a suitable investment for individual retirement accounts, for other tax-exempt or tax-deferred accounts or for investors who are not sensitive to the federal income tax consequences of their investments.

Leverage Risk. The Fund anticipates using leverage to seek to enhance its potential for current income exempt from regular federal income tax. The use of leverage creates special risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of, and distributions on, the Common Shares. The Fund will pay (and Common Shareholders will bear) any costs and expenses relating to the Fund’s use of leverage, which will result in a reduction in the net asset value of the Common Shares. There can be no assurance that the Fund’s leverage strategy will be successful. Furthermore, the amount of fees paid to NFALLC for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets—this may create an incentive for NFALLC to leverage the Fund. See “Risk Factors—Leverage Risk,” “Use of Leverage” and “Risk Factors—Inverse Floating Rate Securities Risk.”

Inverse Floating Rate Securities Risk. The Fund may invest in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third

party sponsor for the purpose of holding municipal bonds. See “The Fund’s Investments—Inverse Floating Rate Securities.” In general, income on inverse floating rate securities will decrease when interest rates increase and increase when interest rates decrease. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal. In addition, inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate, which effectively leverages the Fund’s investment. As a result, the market value of such securities generally will be more volatile than that of fixed rate securities.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party sponsor of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the special purpose trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the special purpose trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party sponsor of the trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.

The Fund’s investments in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund may be highly leveraged. The structure and degree to which the Fund’s inverse floating rate securities are highly leveraged will vary based upon a number of factors, including the size of the trust itself and the terms of the underlying municipal security. An inverse floating rate security generally is considered highly leveraged if the principal amount of the short-term floating rate interests issued by the related special purpose trust is in excess of three times the principal amount of the inverse floating rate securities owned by the trust (the ratio of the principal amount of such short-term floating rate interests to the principal amount of the inverse floating rate securities is referred to as the “gearing”). In the event of a significant decline in the value of an underlying security, the Fund may suffer losses in excess of the amount of its investment (up to an amount equal to the value of the municipal securities underlying the inverse floating rate securities) as a result of liquidating special purpose trusts or other collateral required to maintain the Fund’s anticipated effective leverage ratio.

The Fund’s investment in inverse floating rate securities will create effective leverage, which will create an opportunity for increased

Common Share net income and returns, but will also create the possibility that Common Share long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund.

Inverse floating rate securities have varying degrees of liquidity based upon the liquidity of the underlying securities deposited in a special purpose trust. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. The leverage attributable to such inverse floating rate securities may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. In certain circumstances, the likelihood of an increase in the volatility of net asset value and market price of the Common Shares may be greater for a fund (like the Fund) that relies primarily on inverse floating rate securities to achieve a desired effective leverage ratio. The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

•

If the Fund has a need for cash and the securities in a special purpose trust are not actively trading due to adverse market conditions;

•

If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding special purpose trusts; and

•

If the value of an underlying security declines significantly (to a level below the notional value of the floating rate securities issued by the trust) and if additional collateral has not been posted by the Fund.

See “Risk Factors—Inverse Floating Rate Securities Risk.”

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and distributions can decline. See “Risk Factors—Inflation Risk.”

Derivatives Risk, Including the Risk of Swaps. The Fund’s use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the investments underlying the derivatives. Whether the Fund’s use of derivatives is successful will depend on, among other things, if Nuveen Asset Management correctly forecasts market values, interest rates and other applicable factors. If Nuveen Asset Management incorrectly forecasts these and other factors, the investment performance of the Fund will be unfavorably affected. In addition, the derivatives market is largely unregulated. It is possible that developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments.

Counterparty Risk. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives, insured municipal securities or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have recently incurred significant financial hardships including bankruptcy and losses as a result of exposure to sub-prime mortgages and other lower quality credit investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such hardships have reduced these entities’ capital and called into question their continued ability to perform their obligations under such transactions. By using such derivatives or other transactions, the Fund assumes the risk that its counterparties could experience similar financial hardships. See “Risk Factors—Counterparty Risk.”

Hedging Risk. The Fund’s use of derivatives or other transactions to reduce risks involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so. See “Risk Factors—Hedging Risk.”

Recent Market Conditions. The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt crisis, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many investment companies, including to some extent the Fund. Conditions in the U.S. and global economies have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. The financial condition of federal,

state and local governments may be sensitive to market events, which may, in turn, adversely affect the marketability of notes and bonds they issue. Recent declines in real estate prices and general business activity are reducing tax revenues of many state and local governments and could affect the economic viability of projects that are the sole source of revenue to support various municipal securities. Further, some state and local governments have been and in the future may be subject to direct ballot referenda that could limit their financial flexibility, or their ability to levy taxes or raise tax revenues, which may adversely affect the marketability of notes and bonds issued by those state and local governments. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. Because the situation is widespread and largely unprecedented, it may be unusually difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration of these market conditions. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations. These events could have significant adverse effects on the economy generally.

Anti-Takeover Provisions. The Fund’s Declaration of Trust (the “Declaration”) and the Fund’s By-Laws (the “By-Laws”) include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status. These provisions could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares. See “Certain Provisions in the Declaration of Trust” and “Risk Factors—Anti-Takeover Provisions.”

Potential Conflicts of Interest Risk. NFALLC and Nuveen Asset Management each provide a wide array of portfolio management and other asset management services to a mix of clients and may engage in ordinary course activities in which their respective interests or those of their clients may compete or conflict with those of the Fund. For example, NFALLC and Nuveen Asset Management may provide investment management services to other funds and accounts that follow investment objectives similar to those of the Fund. In certain circumstances, and subject to its fiduciary obligations under the Investment Advisers Act of 1940, Nuveen Asset Management may have to allocate a limited investment opportunity among its clients, which include closed-end funds, open-end funds and other commingled funds. NFALLC and Nuveen Asset Management have each adopted policies and procedures designed to address such situations and other potential conflicts of interests. For additional information about potential conflicts of interest, and the way in which NFALLC and Nuveen Asset Management address such conflicts, please see the SAI.

In addition, an investment in the Fund’s Common Shares raises other risks, which are more fully disclosed in this Prospectus. See “Risk Factors.”

Distributions

The Fund pays monthly cash distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per Common Share dividend rate) based on the projected performance of the Fund. The Fund’s ability to maintain a level Common Share dividend rate will depend on a number of factors, including dividends payable on preferred shares, if issued in the future. As portfolio and market conditions change, the rate of dividends on the Common Shares and the Fund’s dividend policy could change. Over time, the Fund will distribute all of its net investment income (after it pays accrued dividends on any outstanding preferred shares). In addition, the Fund intends to effectively distribute, at least annually, all or substantially all of its net capital gain and taxable ordinary income, if any, to Common Shareholders so long as the net capital gain and taxable ordinary income are not necessary to pay accrued dividends on, or redeem or liquidate, any preferred shares, if issued in the future. You may elect to reinvest automatically some or all of your distributions in additional Common Shares under the Fund’s Dividend Reinvestment Plan.

As explained more fully below under “Tax Matters,” at least annually, the Fund may elect to retain rather than distribute all or a portion of any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) otherwise allocable to Common Shareholders and pay federal income tax on the retained gain. As provided under federal tax law, Common Shareholders of record as of the end of the Fund’s taxable year will include in income for federal income tax purposes as long-term capital gain, his or her share of the retained gain, will be deemed to have paid his or her proportionate share of tax paid by the Fund on such retained gain, and will be entitled to an income tax credit or refund for that share of the tax. The Fund will treat the retained capital gain amount as a substitute for equivalent cash distributions. See “Distributions” and “Dividend Reinvestment Plan.”

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time.

Custodian and Transfer Agent

State Street Bank and Trust Company serves as custodian and transfer agent of the Fund’s assets. See “Custodian and Transfer Agent.”

Special Tax Considerations

The Fund may invest up to 20% of its Managed Assets in AMT Bonds. If you are, or as a result of investment in the Fund would become, subject to the federal alternative minimum tax, the Fund may not be a suitable investment for you. In addition, distributions of ordinary taxable income (including any net short-term capital gain)

will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be subject to capital gains taxes. See “Tax Matters.”

Voting Rights

The Fund does not currently, but may in the future, issue certain types of preferred securities. In that event, such preferred securities, voting as a separate class, would have the right to elect at least two trustees at all times and to elect a majority of the trustees in the event two full years’ dividends on the preferred shares are unpaid. In each case, the remaining trustees would be elected by holders of Common Shares and preferred shares voting together as a single class. The holders of shares of preferred shares would vote as a separate class or classes on certain other matters as required under the Declaration, the Investment Company Act of 1940, as amended (the “1940 Act”) and Massachusetts law. See “Description of Shares—Preferred Shares—Voting Rights” and “Certain Provisions in the Declaration of Trust.”

SUMMARY OF FUND EXPENSES

The table shows the expenses of the Fund as a percentage of the average net assets applicable to Common Shares, and not as a percentage of total assets or Managed Assets.


Shareholder Transaction Expenses (as a percentage of offering price)
Maximum Sales Charge		4.00	%
Offering Costs Borne by the Fund (1)		0.64	%

	As a Percentage of Net Assets Attributable to Common Shares(2)
Annual Expenses
Management Fees		0.22	%
Interest and Related Expenses from Inverse Floaters (3)		0.00	%
Other Expenses (4)		0.07	%

Total Annual Expenses		0.29	%

(1)

Assuming a Common Share offering price of $15.72 (the Fund’s closing price on the NYSE on December 7, 2012).

(2)

Stated as percentages of average net assets attributable to Common Shares for the six months ended September 30, 2012.

(3)

Interest and Related Expenses from Inverse Floaters also includes interest expense that arises because accounting rules require the Fund to treat interest paid by trusts issuing certain inverse floating rate investments held by the Fund as having been paid (indirectly) by the Fund. Because the Fund also recognizes a corresponding amount of interest income (also indirectly), the Fund’s net asset value, net investment income, and total return are not affected by this accounting treatment. The actual Interest and Related Expenses from Inverse Floaters incurred in the future may be higher or lower.

(4)

Other Expenses are estimated based on actual expenses from the prior fiscal period.

The purpose of the table above is to help you understand all fees and expenses that you, as a Common Shareholder, would bear directly or indirectly. See “Management of the Fund—Investment Adviser.”

Examples

The following examples illustrate the expenses (including the applicable transaction fees, if any, and estimated offering costs of $6.40) that a shareholder would pay on a $1,000 investment that is held for the time periods provided in the table. Each example assumes that all dividends and other distributions are reinvested in the Fund and that the Fund’s Annual Expenses, as provided above, remain the same. The examples also assume a 5% annual return.(1)

Example # 1 (At-the-Market Transaction)

The following example assumes a transaction fee of 1.00%, as a percentage of the offering price.


1 Year	3 Years		5 Years		10 Years
$19	$	26	$	32	$	53

Example # 2 (Underwriting Syndicate Transaction)

The following example assumes a transaction fee of 4.00%, as a percentage of the offering price.


1 Year	3 Years		5 Years		10 Years
$49	$	55	$	62	$	82

Example # 3 (Privately Negotiated Transaction)

The following example assumes there is no transaction fee.


1 Year	3 Years		5 Years		10 Years
$9	$	16	$	23	$	43

The examples should not be considered a representation of future expenses. Actual expenses may be greater or less than those shown above.

(1)

The examples assume that all dividends and distributions are reinvested at Common Share net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

FINANCIAL HIGHLIGHTS

The following Financial Highlights table is intended to help a prospective investor understand the Fund’s financial performance for the periods shown. Certain information reflects financial results for a single share of Common Shares of the Fund. The total returns in the table represent the rate an investor would have earned or lost on an investment in Common Shares of the Fund (assuming reinvestment of all dividends). The information with respect to the fiscal year ended March 31, 2012 has been audited by Ernst & Young LLP, whose report for the fiscal year ended March 31, 2012, along with the financial statements of the Fund including the Financial Highlights for each of the periods indicated therein, are included in the Fund’s 2012 Annual Report. Also included is selected data for the six months ended September 30, 2012, which is unaudited and appears in the Fund’s 2012 Semi-Annual Report. A copy of the 2012 Annual Report and the 2012 Semi-Annual Report may be obtained from www.sec.gov or by visiting www.nuveen.com. The information contained in, or that can be accessed through, the Fund’s website is not part of this Prospectus. Past results are not indicative of future performance.

(a)

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.

(b)

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.

USE OF PROCEEDS

The net proceeds from the issuance of Common Shares hereunder will be used by the Fund to invest in municipal securities in accordance with the Fund’s investment objective and policies as stated below. To the extent the Fund uses the net proceeds of any offering to invest in municipal securities, it is presently anticipated that the Fund will be able to invest substantially all of such proceeds in securities that meet the Fund’s investment objective and policies within one month from the date on which the proceeds from an offering are received by the Fund. Pending such investment, it is anticipated that the proceeds will be invested in short-term

or long-term securities issued by the U.S. Government and its agencies or instrumentalities or in high quality, short-term money market instruments. See “Risk Factors—Leverage Risk” and “Use of Leverage.”

THE FUND’S INVESTMENTS

Investment Objective

Investment Philosophy and Process

Philosophy

Nuveen Asset Management believes that the unique tax treatment of municipal securities and the structural characteristics in the municipal securities market create attractive opportunities to enhance the after-tax total return and diversification of the investment portfolios of taxable investors. Nuveen Asset Management believes that these unique characteristics also present unique risks that may be managed to realize the benefits of the asset class. Nuveen Asset Management considers the following factors:

After-Tax Income Potential. The primary source of total return from municipal securities comes from the tax-exempt income derived therefrom. Nuveen Asset Management believes that, at acceptable levels of credit risk and maturity principal risk, the municipal securities market offers the potential for higher after-tax income when compared with other fixed income markets.

Managing Multi-Faceted Risks. Risk in the municipal securities market is derived from multiple sources, including credit risk at the issuer and sector levels, structural risks such as call risk, yield curve risk, and legislative and tax-related risks. Nuveen Asset Management believes that managing these risks at both the individual security and Fund portfolio levels is an important element of realizing the after-tax income and total return potential of the asset class.

Opportunities to Identify Underrated and Undervalued Municipal Securities. Within the state and national municipal securities markets, there are issuers with a wide array of financing purposes, security terms, offering structures and credit quality. Nuveen Asset Management believes that the size, depth and other characteristics of the state and national municipal securities markets offer a broad opportunity set of individual issuers in securities that may be underrated and undervalued relative to the general market.

Market Inefficiencies. Nuveen Asset Management believes that the scale and intricacy of the municipal securities market often results in pricing anomalies and other inefficiencies that can be identified and capitalized on through trading strategies.

Investment Process

Nuveen Asset Management believes that a bottom-up, research-driven investment strategy that seeks to identify underrated and undervalued securities and sectors is positioned to capture the opportunities inherent in the municipal securities market and potentially outperform the general municipal securities market over time. The primary elements of Nuveen Asset Management’s investment process are:

and a priority lien on hard assets, dedicated revenue streams or tax resources. As part of Nuveen Asset Management’s overall risk management process, analysts actively monitor the credit quality of portfolio holdings.

Sector Analysis. Organized by sector, analysts continually assess the key issues and trends affecting each sector in order to maintain a sector outlook. Evaluating such factors as historical default rates and average credit spreads within each sector, analysts provide top-down analysis that supports decisions to overweight or underweight a given sector in a portfolio.

Managing Risk. Nuveen Asset Management seeks to manage portfolio risks, including, principally, exposure to individual credits and sectors and exposure to calls, and to manage a portfolio’s interest rate sensitivity within tolerance bands relative to the relevant benchmark.

Trading Strategies. Through its trading strategies, Nuveen Asset Management seeks to enhance portfolio value by trading to take advantage of inefficiencies found in the municipal market. This may entail selling issues Nuveen Asset Management deems to be overvalued and purchasing issues Nuveen Asset Management considers to be undervalued.

Sell Discipline. Nuveen Asset Management generally sells securities when it (i) determines a security has become overvalued or over-rated, (ii) identifies credit deterioration, or (iii) modifies a portfolio strategy, such as sector allocation.

Investment Policies

As a non-fundamental policy, the Fund seeks to achieve its investment objective by investing in a diversified portfolio of municipal securities at least 80% comprised of investment grade quality securities, the income from which is exempt from regular federal income tax. Nuveen Asset Management seeks to identify and invest in municipal securities that it believes are underrated and undervalued, based on a bottom-up, research-driven investment strategy. Nuveen Asset Management believes its value oriented strategy offers the opportunity to construct a well-diversified portfolio of municipal securities that has the potential to outperform major municipal market benchmarks over the longer term. Underrated municipal securities are those whose credit ratings do not, in Nuveen Asset Management’s opinion, reflect their true creditworthiness. Undervalued municipal securities are securities that, in Nuveen Asset Management’s opinion, are worth more than the value assigned to them in the marketplace. A municipal security’s market value generally will depend upon its form, maturity, call features and interest rate, as well as the issuer’s credit quality or credit rating, all such factors examined in the context of the municipal securities market and interest rate levels and trends. Nuveen Asset Management may at times believe that securities associated with a particular municipal market sector (for example, electric utilities), or issued by a particular municipal issuer, are undervalued. Nuveen Asset Management may purchase such a security for the Fund’s portfolio because it represents a market sector or issuer that Nuveen Asset Management considers undervalued, even if the value of the particular security appears to be consistent with the value of similar securities. Municipal securities of particular types (e.g., hospital bonds, industrial revenue bonds or securities issued by a particular municipal issuer) may be undervalued because there is a temporary excess of supply in that market sector, or because of a general decline in the market price of municipal securities of the market sector for reasons that do not apply to the particular municipal securities that are considered undervalued. A rating issued by an NRSRO is only the opinion of the entity issuing the rating, and is not a guarantee as to quality, or an assurance of the performance, of the rated security. In addition, the manner in which NRSROs obtain and process information about a particular security may affect the NRSRO’s ability to timely react to changes in an issuer’s circumstances that could influence a particular rating. The Fund’s

investment in underrated or undervalued municipal securities will be based on Nuveen Asset Management’s belief that their yield is higher than that available on securities bearing equivalent levels of interest rate risk, credit risk and other forms of risk, and that their prices will ultimately rise (relative to the market) to reflect their true value. The Fund attempts to increase its portfolio value relative to the municipal bond market by prudent selection of municipal securities regardless of the direction the market may move. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to Common Shareholders.

The Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income tax. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects, such as roads, schools, and water supply systems. Municipal securities also may be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility or pollution control projects. Municipal securities may be issued on a long-term basis to provide long-term financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments, and mortgage payments. Municipal securities also may be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms that include fixed coupon, variable rate or zero coupon, including capital appreciation bonds, floating rate securities, and inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships, or other investment companies. The Fund may invest in these types of securities, including floating rate securities and inverse floating rate securities, in order to more efficiently achieve its desired overall portfolio structure as well as enhance its ability to achieve its investment objective.

The Fund intends to use leverage to seek to enhance its potential for current income exempt from regular federal income tax. The Fund intends to use leverage by investing in inverse floating rate securities that have the economic effect of leverage, as discussed further below. The Fund may leverage its capital structure by issuing senior securities such as preferred shares or debt securities or by borrowing. The combined economic effect of the total leverage used by the Fund is referred to as “effective leverage.” The Fund currently uses leverage by investing in inverse floating rate securities. If current market conditions change (for example, if there is a material decrease in the supply of inverse floating rate securities or if newly issued senior securities become a more attractive financing option), the Fund may leverage itself by issuing senior securities such as preferred shares or debt securities, or by borrowing. Financial leverage is created as a result of the Fund’s investments in residual interest certificates of tender option bond trusts, also called inverse floating rate securities, because the Fund’s investment exposure to the underlying bonds held by the trust have been effectively financed by the trust’s issuance of floating rate certificates. In addition, the Fund may borrow for temporary, emergency or other purposes as permitted by the 1940 Act. As of , 2013, the Fund’s total effective leverage was approximately % of its Managed Assets.

There can be no assurance that the Fund’s leverage strategy will be successful. The use of leverage creates special risks for Common Shareholders. See “Use of Leverage,” “Risk Factors—Leverage Risk,” and “Risk Factors—Inverse Floating Rate Securities Risk.”

The Fund also may invest in derivative instruments in pursuit of its investment objective, including inverse floating rate securities. Such also instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts, or other derivative instruments. However, the Fund not enter into futures contracts or related options or forward contracts, if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on futures contracts and related options. Nuveen Asset Management uses derivatives to seek to enhance return, to hedge some of the risks of its

investments in fixed income securities or as a substitute for a position in the underlying asset. These types of hedging strategies may generate taxable income. See “The Fund’s Investments.”

As a fundamental policy, the Fund may invest up to 20% of its Managed Assets in AMT Bonds. Any investment by the Fund will not be counted towards meeting its 80% investment in municipal securities exempt from regular federal income tax and federal alternative minimum tax. Special federal alternative minimum tax rules apply to corporate investors. For a discussion of how the federal alternative minimum tax may affect shareholders, see “Tax Matters.”

Under normal circumstances:

•

As a non-fundamental policy, the Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management. Also as a non-fundamental policy, no more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Asset Management. Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds. See “Risk Factors—Credit and Below Investment Grade Risk.”

•

The Fund will not invest more than 25% of its Managed Assets in municipal securities in any one industry or in any one state of origin and no more than 5% of its Managed Assets in any one issuer.

Any non-fundamental policy of the Fund may be changed by the Fund’s Board following the provision of 60 days prior written notice to Common Shareholders.

The credit quality policies noted above apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, Nuveen Asset Management may consider such factors as Nuveen Asset Management’s assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. A general description of the ratings of municipal securities of S&P, Moody’s and Fitch is set forth in Appendix A to the SAI.

The Fund may purchase municipal securities that are additionally secured by insurance, bank credit agreements or escrow accounts. The credit quality of companies that provide such credit enhancements will affect the value of those securities. Although the insurance feature is designed to reduce certain financial risks, the premiums for insurance and the higher market price paid for insured obligations may reduce the Fund’s income. The Fund may use any insurer, regardless of its rating. A municipal security typically will be deemed to

have the rating of its insurer. However, in the event an insurer has a credit rating below the rating of an underlying municipal security or is perceived by the market to have such a lower rating, the municipal security rating would be the more relevant rating and the value of the municipal security would more closely, if not entirely, reflect such rating. As a result, the value of insurance associated with a municipal security may decline and the insurance may not add any value. The insurance feature normally provides that it guarantees the full payment of principal and interest when due of an insured obligation, but does not guarantee the market value of the insured obligation or the net asset value of the Common Shares represented by such insured obligation. See “Risk Factors—Insurance Risk.”

During temporary defensive periods or in order to keep the Fund’s cash fully invested, including during the period when the net proceeds of the offering of Common Shares are being invested, the Fund may deviate from its investment policies and objectives. During such periods, the Fund may invest up to 100% of its Managed Assets in short-term investments, including high quality, short-term securities that may be either tax-exempt or taxable (or in securities of other open- or closed-end investment companies that invest primarily in municipal securities of the types in which the Fund may invest directly). The Fund may not achieve its investment objectives during such period. The Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Investment in taxable short-term investments would result in a portion of your dividends being subject to regular federal income tax, and if the proportion of taxable investments exceeded 50% of the Fund’s total assets as of the close of any quarter of the Fund’s taxable year, the Fund would not satisfy the general eligibility test that permits it to pay exempt-interest dividends. Such transactions will be used solely to reduce risk. There can be no assurance that such strategies will be successful. For more information, see the SAI under “Tax Matters.”

The Fund’s investment objective and certain investment policies specifically identified as such are considered fundamental and may not be changed without shareholder approval. See “Investment Restrictions” in the SAI. All of the Fund’s other investment policies are not considered to be fundamental by the Fund and can be changed by the Fund’s Board of Trustees without a vote of the Common Shareholders. The Fund cannot change its investment objective or fundamental policies without the approval of the holders of a “majority of the outstanding” Common Shares and preferred shares, if issued in the future, voting together as a single class, and of the holders of a “majority of the outstanding” preferred shares, if issued in the future, voting as a separate class. When used with respect to particular shares of the Fund, a “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less. See “Description of Shares—Preferred Shares—Voting Rights” for additional information with respect to the voting rights of holders of preferred shares.

If you are, or as a result of investment in the Fund would become, subject to the federal alternative minimum tax, the Fund may not be a suitable investment for you because the Fund may invest up to 20% of its Managed Assets in municipal securities that will pay interest that is taxable under the federal alternative minimum tax. Special rules apply to corporate holders. In addition, distributions of net capital gain will be subject to capital gains taxes. See “Tax Matters.”

Municipal Securities

or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms including fixed coupon, variable rate, zero coupon, capital appreciation bonds, tender option bonds, and residual interest bonds or inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships or other investment companies. Inverse floating rate securities are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and represent a leveraged investment in an underlying municipal security, which could have the economic effect of financial leverage.

Municipal securities are either general obligation or revenue bonds and typically are issued to finance public projects (such as roads or public buildings), to pay general operating expenses, or to refinance outstanding debt.

Municipal securities may also be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source; revenue bonds may be repaid only from the revenues of a specific facility or source. The Fund may also purchase municipal securities that represent lease obligations, municipal notes, pre-refunded municipal securities, private activity bonds, tender option bonds and other related securities and derivative instruments that create exposure to municipal bonds, notes and securities and that provide for the payment of interest income that is exempt from regular federal income tax.

The municipal securities in which the Fund will invest are generally issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam), and pay interest that, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by Nuveen Asset Management to be reliable), is exempt from regular federal income tax, although the interest may be subject to the federal alternative minimum tax. The yields on municipal securities depend on a variety of factors, including prevailing interest rates and the condition of the general money market and the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issue. The market value of municipal securities will vary with changes in interest rate levels and as a result of changing evaluations of the ability of their issuers to meet interest and principal payments.

A municipal security’s market value generally will depend upon its form, maturity, call features, and interest rate, as well as the credit quality of the issuer, all such factors examined in the context of the municipal securities market and interest rate levels and trends.

Municipal Leases and Certificates of Participation. The Fund also may purchase municipal securities that represent lease obligations and certificates of participation in such leases. These carry special risks because the issuer of the securities may not be obligated to appropriate money annually to make payments under the lease. A municipal lease is an obligation in the form of a lease or installment purchase which is issued by a state or local government to acquire equipment and facilities. Income from such obligations is generally exempt from state and local taxes in the state of issuance. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment or facilities. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in recovering, or the failure to recover

fully, the Fund’s original investment. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Fund will only purchase municipal securities representing lease obligations where Nuveen Asset Management believes the issuer has a strong incentive to continue making appropriations until maturity.

A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the Fund’s participation interest in the underlying municipal securities, plus accrued interest.

Municipal Notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long- term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Pre-Refunded Municipal Securities. The principal of and interest on pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. The Fund’s distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

When-Issued and Delayed Delivery Transactions. The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. This type of transaction may involve an element of risk because no interest accrues on the bonds prior to settlement and, because bonds are subject to market fluctuations, the value of the bonds at time of delivery may be less (or more) than cost. A separate account of the Fund will be established with its custodian consisting of cash, cash equivalents, or liquid securities having a market value at all times at least equal to the amount of the commitment.

Zero Coupon Bonds. A zero coupon bond is a bond that typically does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, the holder receives the par value of the zero coupon bond, which generates a return equal to the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. This original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon securities and other OID instruments do not pay cash interest at regular intervals, the instruments’ ongoing accruals require ongoing judgments concerning the collectability of deferred payments and the value of any associated collateral. As a result, these securities may be subject to greater value fluctuations and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash on a current basis. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Fund generally will be required to distribute dividends to shareholders representing the income of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

Further, NFALLC collects management fees on the value of a zero coupon bond or OID instrument attributable to the ongoing non-cash accrual of interest over the life of the bond or other instrument. As a result, NFALLC receives non-refundable cash payments based on such non-cash accruals while investors incur the risk that such non-cash accruals ultimately may not be realized.

Inverse Floating Rate Securities

The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. Inverse floating rate securities (sometimes referred to as “inverse floaters”) are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust formed by a third party sponsor for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both

classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees. The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, the institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, the Fund receives the residual cash flow from the special purpose trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security, the Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal security deposited into the special purpose trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the total face value of the short-term floaters in relation to the value of the residual inverse floaters that are issued by the special purpose trust. The Fund expects to make limited investments in inverse floaters, with leverage ratios that may vary at inception between one and three times. In addition, all voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to the Fund, as the holder of the residual inverse floating rate securities.

Because increases in the interest rate on the short-term floaters reduce the residual interest paid on inverse floaters, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater issued by the trust, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater issued by the trust, inverse floaters’ value is generally more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is generally more volatile than the underlying securities due to the leveraging effect of this ownership structure. These securities generally will underperform the market of fixed rate bonds in a rising interest rate environment (i.e., when bond values are falling), but tend to outperform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity based upon the liquidity of the underlying securities deposited in a special purpose trust.

The Fund may invest in inverse floating rate securities, issued by special purpose trusts that have recourse to the Fund. In Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party sponsor of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party sponsor of such inverse floater, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. Such agreements may expose the Fund to a risk of loss that exceeds its investment in the inverse floating rate securities. Absent a shortfall and forbearance agreement, the Fund would not be required to make such a reimbursement. If the Fund chooses not to enter into such an agreement, the special purpose trust could be liquidated and the Fund could incur a loss. See also “Segregation of Assets” in the SAI.

The Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same special purpose trust. The Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts.

Investments in inverse floating rate securities create effective leverage. The use of leverage creates special risks for Common Shareholders. See “Use of Leverage,” “Risk Factors—Leverage Risk,” and “Risk Factors—Inverse Floating Rate Securities Risk.”

Floating Rate Securities. The Fund may also invest in floating rate securities issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.

Structured Notes

The Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss. These types of investments may generate taxable income.

Derivatives

The Fund may invest in certain derivative instruments in pursuit of its investment objective. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments. In particular, the Fund may use credit default swaps and interest rate swaps. Credit default swaps may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. If the Fund is a seller of a contract, the Fund would be required to pay the par (or other agreed upon) value of a referenced debt obligation to the counterparty in the event of a default or other credit event by the reference issuer, such as a U.S. or foreign corporate issuer, with respect to such debt obligations. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would be subject to investment exposure on the notional amount of the swap. If the Fund is a buyer of a contract, the Fund would have the right to deliver a referenced debt obligation and receive the par (or other agreed-upon) value of such debt obligation from the counterparty in the event of a default or other credit event (such as a credit downgrade) by the reference issuer, such as a U.S. or foreign corporation, with respect to its debt obligations. In return, the Fund would pay the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the counterparty would keep the stream of payments and would have no further

obligations to the Fund. Interest rate swaps involve the exchange by the Fund with a counterparty of their respective commitments to pay or receive interest, such as an exchange of fixed-rate payments for floating rate payments. The Fund will usually enter into interest rate swaps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. See “Hedging Strategies and Other Uses of Derivatives” and “Segregation of Assets” in the SAI.

Limitations on the Use of Futures, Futures Options and Swaps. Pursuant to a claim for exemption filed with the National Futures Association on behalf of the Fund, the Fund is not deemed to be a commodity pool operator or a commodity pool under the Commodity Exchange Act (“CEA”) and neither it nor NFALLC or Nuveen Asset Management is currently subject to registration or regulation as such under the CEA with respect to the Fund. In February 2012, the Commodity Futures Trading Commission (“CFTC”) announced substantial amendments to certain exemptions, and to the conditions for reliance on those exemptions, from registration as a commodity pool operator. Under amendments to the exemption provided under CFTC Regulation 4.5, if the Fund uses futures, options on futures, or swaps other than for bona fide hedging purposes (as defined by the CFTC), the aggregate initial margin and premiums on these positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are “in-the-money” at the time of purchase are “in-the-money”) may not exceed 5% of the Fund’s net asset value, or alternatively, the aggregate net notional value of those positions may not exceed 100% of the Fund’s net asset value (after taking into account unrealized profits and unrealized losses on any such positions). The CFTC amendments to Regulation 4.5 went into effect December 31, 2012 and the Fund intends to comply with amended Regulation 4.5’s requirements such that NFALLC and/or Nuveen Asset Management will not be required to register with respect to the Fund as a commodity pool operator with the CFTC. The Fund reserves the right to engage in transactions involving futures, options thereon and swaps to the extent allowed by CFTC regulations in effect from time to time and in accordance with the Fund’s policies. The requirements for qualification as a regulated investment company may limit the extent to which the Fund may enter into futures transactions, engage in options transactions or engage in swap transactions.

Nuveen Asset Management may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income.

There is no assurance that these derivative strategies will be available at any time or that Nuveen Asset Management will determine to use them for the Fund or, if used, that the strategies will be successful.

Other Investment Companies

As a non-fundamental policy, the Fund may invest up to 10% of its Managed Assets in securities of other open- or closed-end investment companies (including exchange-traded funds (“ETFs”)) that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, the Fund may invest a portion of its Managed Assets in pooled investment vehicles (other than investment companies) that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund may invest in investment companies that are advised by the NFALLC, Nuveen Asset Management or their respective affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. The Fund has not applied for and currently does not intend to apply for such relief. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s advisory and administrative fees with respect to assets so invested. Common shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies.

Nuveen Asset Management will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same

leverage risks described herein. As described in the section entitled “Risk Factors,” the net asset value and market value of leveraged shares will be more volatile and the yield to Common Shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

Portfolio Turnover

The Fund may buy and sell municipal securities to accomplish its investment objectives in relation to actual and anticipated changes in interest rates. The Fund also may sell one municipal security and buy another of comparable quality at about the same time to take advantage of what Nuveen Asset Management believes to be a temporary price disparity between the two bonds that may result from imbalanced supply and demand. The Fund also may engage in a limited amount of short-term trading, consistent with its investment objectives. The Fund may sell securities in anticipation of a market decline (a rise in interest rates) or buy securities in anticipation of a market rise (a decline in interest rates) and later sell them, but the Fund will not engage in trading solely to recognize a gain. The Fund will attempt to achieve its investment objectives by prudently selecting municipal securities with a view to holding them for investment. Although the Fund cannot accurately predict its annual portfolio turnover rate, the Fund expects, though it cannot guarantee, that its annual portfolio turnover rate generally will not exceed 100% under normal circumstances. For the six months ended September 30, 2012, the Fund’s portfolio turnover rate was 17%. There are no limits on the rate of portfolio turnover, and investments may be sold without regard to length of time held when investment considerations warrant such action. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. In addition, high portfolio turnover may result in the realization of net short term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income. See “Tax Matters.”

USE OF LEVERAGE

The Fund intends to use leverage to seek to enhance its potential for current income exempt from regular federal income tax. The Fund intends to use leverage by investing in inverse floating rate securities that have the economic effect of leverage, as discussed further below. The Fund may leverage its capital structure by issuing senior securities such as preferred shares, investing in debt securities or by borrowing. The combined economic effect of the total leverage used by the Fund is referred to as “effective leverage.” The Fund currently uses leverage by investing in inverse floating rate securities. If current market conditions change (for example, if there is a material decrease in the supply of inverse floating rate securities or if newly issued senior securities become a more attractive financing option), the Fund may use other forms of leverage. Financial leverage is created as a result of the Fund’s investments in residual interest certificates of tender option bond trusts, also called inverse floating rate securities, because the Fund’s investment exposure to the underlying bonds held by the trust have been effectively financed by the trust’s issuance of floating rate certificates. As of , 2013 the Fund’s total effective leverage was approximately % of its Managed Assets.

The Fund does not currently have any preferred shares or debt securities outstanding or any borrowings. The Fund may issue preferred shares or debt securities or borrow in the future to increase the Fund’s leverage. The timing and terms of any leverage transactions is determined by the Fund’s Board of Trustees. Borrowings and preferred shares, if any, will have seniority over the Common Shares.

Following an offering of additional Common Shares from time to time, the Fund’s leverage ratio will decrease as a result of the increase in net assets attributable to Common Shares. The Fund’s leverage ratio may decline further to the extent that the net proceeds of an offering of Common Shares are used to reduce the Fund’s financial leverage. A lower leverage ratio may result in lower (higher) returns to Common Shareholders over a period of time to the extent that net returns on the Fund’s investment portfolio exceed (fall below) its cost of leverage over that period, which lower (higher) returns may impact the level of the Fund’s distributions. See “Risk Factors—Leverage Risk and Inverse Floating Rate Securities.” Portfolio leverage is created through the

Fund’s investments in inverse floating rate securities, because the Fund’s investment exposure to the underlying bonds held by the trust issuing the inverse floaters have been effectively financed by the trust’s issuance of floating rate certificates. See “Risk Factors—Inverse Floating Rate Securities Risk.”

The Fund pays NFALLC a management fee based on a percentage of net assets. Net assets for this purpose includes the proceeds realized from the Fund’s use of financial leverage. See “Management of the Fund—Investment Management and Investment Sub-Advisory Agreements.” NFALLC will base its decision whether and how much to leverage the Fund based solely on its assessment of whether such use of leverage will advance the Fund’s investment objective. NFALLC will be responsible for using leverage to achieve the Fund’s investment objective. However, the fact that a decision to increase the Fund’s leverage will have the effect of increasing net assets, and therefore NFALLC’s management fee, means that NFALLC may have an incentive to increase the Fund’s use of leverage. NFALLC will seek to manage that incentive by only increasing the Fund’s use of leverage when it determines that such increase is consistent with the Fund’s investment objective, and by periodically reviewing the Fund’s performance and use of leverage with the Fund’s Board of Trustees.

Leverage involves special risks. There is no assurance that the Fund’s leveraging strategy will be successful.

RISK FACTORS

Risk is inherent in all investing. Investing in any investment company security involves risk, including the risk that you may receive little or no return on your investment or even that you may lose part or all of your investment. Therefore, before investing you should consider carefully the following risks that you assume when you invest in Common Shares.

Investment and Market Risk

An investment in the Fund’s Common Shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Common Shares represents an indirect investment in the municipal securities owned by the Fund, which generally trade in the over-the-counter markets. Your Common Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions. In addition, if the current national economic downturn deteriorates into a prolonged recession, the ability of municipalities to collect revenue and service their obligations could be materially and adversely affected.

Market Discount from Net Asset Value

Shares of closed-end investment companies like the Fund have during some periods traded at prices lower than net asset value. The Fund cannot predict whether Common Shares will trade at, above or below net asset value. This characteristic is a risk separate and distinct from the risk that the Fund’s net asset value could decrease as a result of investment activities. Investors bear a risk of loss to the extent that the price at which they sell their shares is lower in relation to the Fund’s net asset value than at the time of purchase, assuming a stable net asset value. Proceeds from the sale of Common Shares in this offering will be reduced by transaction costs (if applicable, which vary depending on the offering method used). Depending on the premium of the Common Shares at the time of any offering of Common Shares hereunder, the Fund’s net asset value may be reduced by an amount up to the offering costs borne by the Fund (estimated to be an additional % of the offering price assuming a Common Share offering price of $ (the Fund’s closing price on the NYSE on , 2013)). The net asset value per Common Share will be reduced by costs associated with any future offerings of Common or preferred shares. The Common Shares are designed primarily for long-term investors, and you should not view the Fund as a vehicle for trading purposes.

Credit and Below Investment Grade Risk

Credit risk is the risk that one or more municipal securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer of the security experiences a decline in its financial status. In general, lower-rated municipal securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund’s net asset value or dividends. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. The Fund may invest up to 20% of its Managed Assets in municipal securities that are rated below investment grade at the time of investment or that are unrated but judged to be of comparable quality by Nuveen Asset Management. If a municipal security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, Nuveen Asset Management will consider what action, including the sale of the security, is in the best interests of the Fund and its shareholders. This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities). Municipal securities of below investment grade quality, commonly referred to as junk bonds, are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal when due, and are susceptible to default or decline in market value due to adverse economic and business developments. Also, to the extent that the rating assigned to a municipal security in the Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for municipal securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade municipal securities. For these reasons, an investment in the Fund, compared with a portfolio consisting solely of investment grade securities, may experience the following:

•

increased price sensitivity resulting from changing interest rates and/or a deteriorating economic environment;

•

greater risk of loss due to default or declining credit quality;

•

adverse issuer specific events that are more likely to render the issuer unable to make interest and/or principal payments; and

•

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a below investment grade issuer to make principal payments and interest payments compared to an investment grade issuer. The principal amount of below investment grade securities outstanding has proliferated in the past decade as an increasing number of issuers have used below investment grade securities for financing. The current downturn may severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. As the national economy experiences the current economic downturn, resulting in decreased tax and other revenue streams of municipal issuers, or in the event interest rates rise sharply, increasing the interest cost on variable rate instruments and negatively impacting economic activity, the number of defaults by below investment grade municipal issuers is likely to increase. Similarly, downturns in profitability in specific industries could adversely affect private activity bonds. The market values of lower quality debt securities tend to reflect individual developments of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse impact on the Fund’s net asset value and the market value of its Common Shares. In addition, the Fund may incur additional expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the Fund may be required to foreclose on an issuer’s assets and take possession of its property or operations. In such circumstances, the Fund would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for below investment grade securities may not be as liquid as the secondary market for more highly rated securities, a factor that may have an adverse effect on the Fund’s ability to dispose of a particular security. There are fewer dealers in the market for below investment grade municipal securities than the market for investment grade municipal securities. The prices quoted by different dealers for below investment grade municipal securities may vary significantly, and the spread between the bid and ask price is generally much larger for below investment grade municipal securities than for higher quality instruments. Under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under these circumstances, may be less than the prices used in calculating the Fund’s net asset value.

Issuers of such below investment grade securities are highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with higher rated securities. For example, during an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of below investment grade securities may experience financial stress. During such periods, such issuers may not have sufficient revenues to meet their interest payment obligations. The issuer’s ability to service its debt obligations also may be adversely affected by specific developments, the issuer’s inability to meet specific projected forecasts or the unavailability of additional financing. The risk of loss from default by the issuer is significantly greater for the holders of below investment grade securities because such securities are generally unsecured and are often subordinated to other creditors of the issuer. Prices and yields of below investment grade securities will fluctuate over time and, during periods of economic uncertainty, volatility of below investment grade securities may adversely affect the Fund’s net asset value. In addition, investments in below investment grade zero coupon bonds rather than income-bearing below investment grade securities, may be more speculative and may be subject to greater fluctuations in value due to changes in interest rates.

The Fund may invest in distressed securities, which are securities issued by companies that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition by the Fund. The issuers of such securities may be in transition, out of favor, financially leveraged or troubled, or potentially troubled, and may be or have recently been involved in major strategic actions, restructurings, bankruptcy, reorganization or liquidation. These characteristics of these companies can cause their securities to be particularly risky, although they also may offer the potential for high returns. These companies’ securities may be considered speculative, and the ability of the companies to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the companies. Distressed securities frequently do not produce income while they are outstanding and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such distressed securities may not be clear.

Interest Rate Risk

Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in the Fund’s portfolio will decline in value because of increases in market interest rates. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the

prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change. Because the Fund will invest primarily in longer-term municipal securities, the Common Share net asset value and market price per share will fluctuate more in response to changes in market interest rates than if the Fund invested primarily in shorter-term municipal securities. Because the values of lower-rated and comparable unrated debt securities are affected both by credit risk and interest rate risk, the price movements of such lower grade securities typically have not been highly correlated to the fluctuations of the prices of investment grade quality securities in response to changes in market interest rates. The Fund’s use of leverage, as described herein, will tend to increase Common Share interest rate risk.

Municipal Securities Market Risk

Investing in the municipal securities market involves certain risks. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the recent market turmoil these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal bonds. The amount of public information available about the municipal securities in the Fund’s portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of Nuveen Asset Management than if the Fund were a stock fund or taxable bond fund. The secondary market for municipal securities, particularly the below investment grade bonds in which the Fund may invest, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its municipal securities at attractive prices or at prices approximating those at which the Fund currently values them.

The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Fund could experience delays in collecting principal and interest and the Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt.

Reinvestment Risk

Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Common Shares’ market price or their overall returns.

Leverage Risk

The Fund anticipates using leverage to seek to enhance total returns. The use of leverage creates special risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of, and distributions on, the Common Shares. The Fund will pay (and Common Shareholders will bear) any costs and expenses relating to the Funds’ use of leverage, which will result in a reduction in the net asset value of the Common Shares. There can be no assurance that the Fund’s leverage strategy will be successful. Furthermore, the amount of fees paid to NFALLC for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets—this may create an incentive for Nuveen Asset Management to leverage the Fund. See “Risk Factors—Leverage Risk” and “Risk Factors—Inverse Floating Rate Securities Risk.”

Inverse Floating Rate Securities Risk

The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third party sponsor for the purpose of holding municipal bonds. See “Municipal Securities—Inverse Floating Rate Securities.” In general, income on inverse floating rate securities will decrease when interest rates increase and increase when interest rates decrease. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party sponsor of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party sponsor of the trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.

Inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate, which effectively leverages the Fund’s investment. As a result, the market value of such securities generally will be more volatile than that of fixed rate securities.

The Fund’s investments in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund may be highly leveraged. The structure and degree to which the Fund’s inverse floating rate securities are highly leveraged will vary based upon a number of factors, including the size of the trust itself and the terms of the underlying municipal security. An inverse floating rate security generally is considered highly leveraged if the principal amount of the short-term floating rate interests issued by the related special purpose trust has a three to one gearing to the principal amount of the inverse floating rate securities owned by the trust. In the event of a significant decline in the value of an underlying security, the Fund may suffer losses in excess of the amount of its investment (up to an amount equal to the value of the municipal securities underlying the inverse floating rate securities) as a result of liquidating special purpose trusts or other collateral required to maintain the Fund’s anticipated effective leverage ratio.

The Fund’s investment in inverse floating rate securities will create effective leverage. Any effective leverage achieved through the Fund’s investment in inverse floating rate securities will create an opportunity for increased Common Share net income and returns, but will also create the possibility that Common Share long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund. See “Risk Factors—Leverage Risk.”

The amount of fees paid to Nuveen Asset Management for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets—this may create an incentive for Nuveen Asset Management to leverage the Fund. Managed Assets means the total assets of the Fund, minus the sum of its accrued liabilities (other than liabilities incurred for the express purpose of creating effective leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to, the portion of assets in special purpose trusts of which the Fund owns the inverse floater certificates that has been effectively financed by the trust’s issuance of floating rate certificates.

There is no assurance that the Fund’s strategy of investing in inverse floating rate securities will be successful.

Inverse floating rate securities have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in a special purpose trust. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. The leverage attributable to such inverse floating rate securities may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. In certain circumstances, the likelihood of an increase in the volatility of net asset value and market price of the Common Shares may be greater for a fund (like the Fund) that relies primarily on inverse floating rate securities to achieve a desired effective leverage ratio. The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

•

If the Fund has a need for cash and the securities in a special purpose trust are not actively trading due to adverse market conditions;

•

If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding trusts; and

•

Insurance Risk

The Fund may purchase municipal securities that are secured by insurance, bank credit agreements or escrow accounts. The credit quality of the companies that provide such credit enhancements will affect the value of those securities. Certain significant providers of insurance for municipal securities have recently incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the rating of the underlying municipal security will be more relevant and the value of the municipal security would more closely, if not entirely, reflect such rating. In such a case, the value of insurance associated with a municipal security would decline and may not add any value. The insurance feature of a municipal security does not guarantee the full payment of principal and interest through the life of an insured obligation, the market value of the insured obligation or the net asset value of the Common Shares represented by such insured obligation.

Tax Risk

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, among other things, the Fund must derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy a diversification test on a quarterly basis. If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions were not available to the Fund and it were to fail to qualify for treatment as a regulated investment company for a taxable year, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to stockholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

obligations exempt from regular income tax as of the close of each quarter of the Fund’s taxable year. If the proportion of taxable investments held by the Fund exceeds 50% of the Fund’s total assets as of the close of any quarter of any Fund taxable year, the Fund will not satisfy for that taxable year the general eligibility test that otherwise permits it to pay exempt-interest dividends for the taxable year.

Taxability Risk

The Fund will invest in municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for federal income tax purposes, and Nuveen Asset Management will not independently verify that opinion. Subsequent to the Fund’s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid, taxable income. As a result, the treatment of dividends previously paid or to be paid by the Fund as “exempt-interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased federal income tax liabilities.

Distributions of ordinary taxable income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxable as long-term capital gains. See “Tax Matters.”

Borrowing Risks

In addition to borrowing for leverage (See “Use of Leverage”), the Fund may borrow for temporary or emergency purposes, including to meet redemption requests, pay dividends, repurchase its shares, or clear portfolio transactions. Borrowing may exaggerate changes in the net asset value of the Fund’s shares and may affect the Fund’s net income. When the Fund borrows money, it must pay interest and other fees, which will reduce the Fund’s returns if such costs exceed the returns on the portfolio securities purchased or retained with such borrowings. Any such borrowings are intended to be temporary. However, under certain market conditions, including periods of low demand or decreased liquidity in the municipal bond market such borrowings might be outstanding for longer periods of time. The Fund will not purchase additional portfolio securities while outstanding such temporary or emergency borrowings exceed 5% of the value of its total assets.

Inflation Risk

Inflation risk is the risk that the value of assets or income from investment will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of Common Shares and the distributions can decline. In addition, during any period of rising inflation, interest rates on borrowings would likely increase, which would tend to further reduce returns to Common Shareholders.

Sector and Industry Risk

The Fund may invest up to 25% of its net assets in municipal securities in any one industry or in any one state of origin. In addition, subject to the concentration limits of the Fund’s investment policies and guidelines,

the Fund may invest a significant portion of its net assets in certain sectors of the municipal securities market, such as hospitals and other health care facilities, charter schools and other private educational facilities, special taxing districts and start-up utility districts, and private activity bonds including industrial development bonds on behalf of transportation companies such as airline companies, whose credit quality and performance may be more susceptible to economic, business, political, regulatory and other developments than other sectors of municipal issuers. If the Fund invests a significant portion of its net assets in the sectors noted above, the Fund’s performance may be subject to additional risk and variability. To the extent that the Fund focuses its net assets in the hospital and healthcare facilities sector, for example, the Fund will be subject to risks associated with such sector, including adverse government regulation and reduction in reimbursement rates, as well as government approval of products and services and intense competition. Securities issued with respect to special taxing districts will be subject to various risks, including real-estate development related risks and taxpayer concentration risk. Further, the fees, special taxes or tax allocations and other revenues established to secure the obligations of securities issued with respect to special taxing districts are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. Charter schools and other private educational facilities are subject to various risks, including the reversal of legislation authorizing or funding charter schools, the failure to renew or secure a charter, the failure of a funding entity to appropriate necessary funds and competition from alternatives such as voucher programs. Issuers of municipal utility securities can be significantly affected by government regulation, financing difficulties, supply and demand of services or fuel and natural resource conservation. The transportation sector, including airports, airlines, ports and other transportation facilities, can be significantly affected by changes in the economy, fuel prices, labor relations, insurance costs and government regulation.

Special Risks Related to Certain Municipal Obligations

The Fund may invest in municipal leases and certificates of participation in such leases. Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover the Fund’s original investment. In the event of non-appropriation, the issuer would be in default and taking ownership of the assets may be a remedy available to the Fund, although the Fund does not anticipate that such a remedy would normally be pursued. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. Certificates of participation, which represent interests in unmanaged pools of municipal leases or installment contracts, involve the same risks as the underlying municipal leases. In addition, the Fund may be dependent upon the municipal authority issuing the certificates of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.

Derivatives Risk, Including the Risk of Swaps

The Fund’s use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the investments underlying the derivatives. Whether the Fund’s use of derivatives is

successful will depend on, among other things, if Nuveen Asset Management correctly forecasts market values, interest rates and other applicable factors. If Nuveen Asset Management incorrectly forecasts these and other factors, the investment performance of the Fund will be unfavorably affected. In addition, the derivatives market is largely unregulated. It is possible that developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments.

The Fund may enter into debt-related derivatives instruments including credit swap default contracts and interest rate swaps. Like most derivative instruments, the use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of swaps requires an understanding by Nuveen Asset Management not only of the referenced asset, rate or index, but also of the swap itself. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. It is possible that developments in the swaps market, including potential government regulation, could adversely affect the Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements. The derivatives market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments. See also, “Risk Factors—Counterparty Risk”, “Risk Factors—Hedging Risk” and the SAI.

Counterparty Risk

Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives, insured municipal securities or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have recently incurred significant financial hardships including bankruptcy and losses as a result of exposure to sub-prime mortgages and other lower quality credit investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such hardships have reduced these entities’ capital and called into question their continued ability to perform their obligations under such transactions. By using such derivatives or other transactions, the Fund assumes the risk that its counterparties could experience similar financial hardships.

Hedging Risk

The Fund’s use of derivatives or other transactions to reduce risk involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

Deflation Risk

Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Recent Market Conditions

The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt crisis, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many investment companies,

including to some extent the Fund. Conditions in the U.S. and global economies have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. The financial condition of federal, state and local governments may be sensitive to market events, which may, in turn, adversely affect the marketability of notes and bonds they issue. Recent declines in real estate prices and general business activity are reducing tax revenues of many state and local governments and could affect the economic viability of projects that are the sole source of revenue to support various municipal securities. Further, some state and local governments have been and in the future may be subject to direct ballot referenda that could limit their financial flexibility, or their ability to levy taxes or raise tax revenues, which may adversely affect the marketability of notes and bonds issued by those state and local governments. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. Because the situation is widespread and largely unprecedented, it may be unusually difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration of these market conditions. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations. These events could have significant adverse effects on the economy generally.

Illiquid Securities Risk

The Fund may invest up to 15% of its Managed Assets in municipal securities and other instruments that, at the time of investment, are illiquid. Illiquid securities are securities that are not readily marketable and may include some restricted securities, which are securities that may not be resold to the public without an effective registration statement under the 1933 Act, if they are unregistered, may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximating the value at which the Fund is carrying the securities on its books.

Market Disruption Risk

Certain events have a disruptive effect on the securities markets, such as terrorist attacks (including the terrorist attacks in the U.S. on September 11, 2001), war and other geopolitical events. The Fund cannot predict the effects of similar events in the future on the U.S. economy. Below investment grade securities tend to be more volatile than higher rated securities so that these events and any actions resulting from them may have a greater impact on the prices and volatility of below investment grade securities than on higher rated securities.

Impact of Offering Methods Risk

The issuance of Common Shares through the various methods described in the Prospectus may have an adverse effect on prices in the secondary market for the Fund’s Common Shares by increasing the number of Common Shares available for sale. In addition, the Common Shares may be issued at a discount to the market price for such Common Shares, which may put downward pressure on the market price for Common Shares of the Fund.

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund, NFALLC and/or Nuveen Investments. Absent an exemption from the SEC or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. The Fund has not applied for and does not currently intend to apply for such relief. This could limit the Fund’s ability to engage in securities transactions, purchase certain adjustable rate senior loans, if applicable, and take advantage of market opportunities. In addition, unless and

until the underwriting syndicate is broken in connection with the initial public offering of the Common Shares, the Fund will be precluded from effecting principal transactions with brokers who are members of the syndicate.

Anti-Takeover Provisions

The Fund’s Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status. These provisions could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares. See “Certain Provisions in the Declaration of Trust.”

HOW THE FUND MANAGES RISK

Investment Limitations

The Fund has adopted certain investment limitations designed to limit investment risk and maintain portfolio diversification. These limitations are fundamental and may not be changed without the approval of the holders of a “majority of the outstanding” Common Shares and preferred shares, if issued in the future, voting together as a single class, and, if issued in the future, the approval of the holders of a “majority of the outstanding” preferred shares voting as a separate class. When used with respect to particular shares of the Fund, a “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less.

The Fund may become subject to guidelines which are more limiting than the investment limitations referred to above in order to obtain and maintain ratings from Moody’s, S&P or Fitch on the preferred shares, if issued in the future, including with respect to the Fund’s hedging strategies described below. The Fund does not anticipate that such guidelines would have a material adverse effect on the Fund’s Common Shareholders or the Fund’s ability to achieve its investment objective. See “Investment Objectives” in the SAI for information about these guidelines and a complete list of the fundamental and non-fundamental investment policies of the Fund.

Quality Investments

Under normal circumstances and as a non-fundamental policy, the Fund will invest at least 80% of its Managed Assets in investment grade securities that, at the time of investment are rated within the four highest grades (Baa or BBB or better) by at least one of the NRSROs or are unrated but judged to be of comparable quality by Nuveen Asset Management.

Derivative Instruments

As previously noted, the Fund may invest in certain derivative instruments in pursuit of its investment objective. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts, or other derivative instruments. Nuveen Asset Management may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of hedging strategies may generate taxable income.

MANAGEMENT OF THE FUND

Trustees and Officers

The Board of Trustees is responsible for the management of the Fund, including supervision of the duties performed by NFALLC. The names and business addresses of the trustees and officers of the Fund and their principal occupations and other affiliations during the past five years are set forth under “Management of the Fund” in the SAI.

Investment Management and Sub-Advisory Agreements

Investment Management Agreement. Pursuant to an investment management agreement between NFALLC and the Fund (the “Investment Management Agreement”), the Fund has agreed to pay an annual management fee for the services and facilities provided by NFALLC, payable on a monthly basis, based on the sum of a fund-level fee and a complex-level fee, as described below.

Fund-Level Fee. The annual fund-level fee for the Fund, payable monthly, is calculated according to the following schedule:


Average Daily Managed Assets⁽¹⁾	Fund-Level Fee Rate
For the first $125 million		0.0500	%
For the next $125 million		0.0375	%
For the next $250 million		0.0250	%
For the next $500 million		0.0125	%

Complex-Level Fee. The annual complex-level fee for the Fund, payable monthly, is calculated according to the following schedule:


Complex-Level Managed Asset Breakpoint Level⁽²⁾	Effective Rate at Breakpoint Level
$55 billion		0.2000	%
$56 billion		0.1996	%
$57 billion		0.1989	%
$60 billion		0.1961	%
$63 billion		0.1931	%
$66 billion		0.1900	%
$71 billion		0.1851	%
$76 billion		0.1806	%
$80 billion		0.1773	%
$91 billion		0.1691	%
$125 billion		0.1599	%
$200 billion		0.1505	%
$250 billion		0.1469	%
$300 billion		0.1445	%

(1)

For the Fund, “Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to, the portion of assets in special purpose trusts of which the Fund owns the inverse floater certificates that has been effectively financed by the trust’s issuance of floating rate certificates.

(2)

The complex-level fee is calculated based upon the aggregate daily “eligible assets” of all Nuveen Funds. Eligible assets do not include assets attributable to investments in other Nuveen Funds or assets in excess of a determined amount (originally $2 billion) added to the Nuveen fund complex in connection with NFALLC’s assumption of the management of the former First American Funds effective January 1, 2011. With respect to closed-end funds, eligible assets include assets managed by NFALLC that are attributable to financial leverage. For these purposes, financial leverage includes the use of preferred stock and borrowings and certain investments in the residual interest certificates in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by issuance of floating rate securities, subject to an agreement by NFALLC as to certain funds to limit the amount of such assets for determining eligible assets in certain circumstances. As of September 30, 2012, the complex-level fee rate for the Fund was 0.1695%.

A discussion regarding the basis for the Board of Trustees’ decision to renew the Investment Management Agreement for the Fund is available in the Fund’s semi-annual report to shareholders dated September 30, 2012.

Sub-Advisory Agreement. Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management receives from NFALLC a management fee equal to 60.000% of NFALLC’s net management fee from the Fund. NFALLC and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

In addition to the fee of NFALLC, the Fund pays all other costs and expenses of its operations, including compensation of its trustees (other than those affiliated with NFALLC and Nuveen Asset Management), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses associated with any Borrowings, expenses of issuing any preferred shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports

to governmental agencies, and taxes, if any. All fees and expenses are accrued daily and deducted before payment of dividends to investors.

A discussion regarding the basis for the Board of Trustees’ decision to renew the Sub-Advisory Agreement for the Fund is available in the Fund’s semi-annual report to shareholders dated September 30, 2012.

NET ASSET VALUE

The Fund’s net asset value per share is determined as of the close of regular session trading (normally 4:00 p.m., Eastern Time) on each day the NYSE is open for business. Net asset value is calculated by taking the market value of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share. All valuations are subject to review by the Fund’s Board of Trustees or its delegate.

In determining net asset value, expenses are accrued and applied daily and securities and other assets for which market quotations are available are valued at market value. The prices of municipal bonds are provided by a pricing service approved by the Fund’s Board of Trustees. When market price quotes are not readily available (which is usually the case for municipal securities), the pricing service, or, in the absence of a pricing service for a particular security, the Board of Trustees of the Fund, or its designee, may establish fair market value using a wide variety of market data including yields or prices of municipal bonds of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from securities dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant by the pricing service or the Board of Trustees’ designee. Exchange-listed securities are generally valued at the last sales price on the securities exchange on which such securities are primarily traded. Securities traded on a securities exchange for which there are no transactions on a given day or securities not listed on a securities exchange are valued at the mean of the closing bid and asked prices. Securities traded on Nasdaq are valued at the Nasdaq Official Closing Price. Temporary investments in securities that have variable rate and demand features qualifying them as short-term investments are valued at amortized cost, which approximates market value. See “Net Asset Value” in the SAI for more information.

DISTRIBUTIONS

The Fund pays regular monthly cash distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per Common Share dividend rate) that reflects the past and projected performance of the Fund. Distributions can only be made from net investment income after paying any accrued dividends to preferred shareholders, if any, or interest and required principal payments on borrowings.

The Fund’s ability to maintain a level dividend rate will depend on a number of factors. The net income of the Fund includes all interest income accrued on portfolio assets less all expenses of the Fund. Expenses of the Fund are accrued each day. For each year, all or substantially all the net investment income of the Fund will be distributed. At least annually, the Fund also intends to distribute substantially all of its net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) and ordinary taxable income, if any, after paying any accrued dividends or making any liquidation payments to preferred shareholders, if any, and interest and required principal payments on borrowings. Although it does not now intend to do so, the Board of Trustees may change the Fund’s dividend policy and the amount or timing of the distributions, based on a number of factors, including the amount of the Fund’s undistributed net investment income and historical and projected investment income and the amount of the expenses and dividend rates on the outstanding preferred shares, if any, and expenses and interest on borrowings.

The Fund might not distribute all or a portion of any net capital gain for a taxable year. If the Fund does not distribute all of its net capital gain for a taxable year, it will pay federal income tax on the retained gain. Each

Common Shareholder of record as of the end of the Fund’s taxable year will include in income for federal income tax purposes as long-term capital gain, his or her share of the retained gain, will be deemed to have paid his or her proportionate share of tax paid by the Fund on such retained gain, and will be entitled to an income tax credit or refund for that share of the tax. The Fund will treat the retained capital gains as a substitute for equivalent cash distributions. The Fund may make total distributions during a given calendar year in an amount that exceeds the Fund’s net investment income and net capital gain for that calendar year, in which case the excess would generally be treated by Common Stockholders as a return of capital for tax purposes.

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time.

DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (“Plan”), you may elect to have all dividends, including any capital gain dividends, on your Common Shares automatically reinvested by the Plan Agent (defined below) in additional Common Shares under the Plan. You may elect to participate in the Plan by contacting Nuveen Investor Services at (800) 257-8787. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you or your brokerage firm by State Street Bank and Trust Company as dividend paying agent (“Plan Agent”).

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

(1) If Common Shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the then current market price;

(2) If Common Shares are trading below net asset value at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or elsewhere, for the participants’ accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments; or

(3) 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.

You may withdraw from the Plan at any time by giving written notice to the Plan Agent. If you withdraw or the Plan is terminated, you will receive whole shares in your account under the Plan and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions and a $2.50 service fee.

The Plan Agent maintains all shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Upon a repurchase of your shares, the Fund (or its administrative agent) may be required to report to the IRS and furnish to you cost basis and holding period information for Fund shares that you purchased on or after January 1, 2012 (“covered shares”).

Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions.

If you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above. Consult your financial advisor for more information.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing to State Street Bank and Trust Company, Attn: ComputerShare Nuveen Investments, P.O. Box 43071, Providence, Rhode Island 02940-3071 or by calling (800) 257-8787.

The minimum price on any day will not be less than the current net asset value per Common Share plus the per share amount of the commission to be paid to Nuveen Securities. The Fund and Nuveen Securities will suspend the sale of Common Shares if the per share price of the shares is less than the minimum price.

The Fund will compensate Nuveen Securities with respect to sales of the Common Shares at a commission rate of 1% of the gross proceeds of the Sale of Common Shares. Nuveen Securities will compensate broker-dealers participating in the offering at a rate of 0.8% of the gross proceeds of the Sale of Common Shares sold by that broker-dealer. Nuveen Securities may from time to time change the dealer re-allowance. Settlements of sales of Common Shares will occur on the third business day following the date on which any such sales are made.

In connection with the sale of the Common Shares on behalf of the Fund, Nuveen Securities may be deemed to be an underwriter within the meaning of the 1933 Act, and the compensation of Nuveen Securities may be deemed to be underwriting commissions or discounts. Unless otherwise indicated in a further Prospectus supplement, Nuveen Securities will act as underwriter on a reasonable efforts basis.

The offering of Common Shares pursuant to the Distribution Agreement will terminate upon the earlier of (i) the sale of all Common Shares subject thereto or (ii) termination of the Distribution Agreement. The Fund and Nuveen Securities each have the right to terminate the Distribution Agreement in its discretion at any time.

The Fund’s closing price on the NYSE on , 2013 was $ .

Distribution Through Underwriting Syndicates

The Fund from time to time may issue additional Common Shares through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s Common Shares, underwriters will market and price the offering on an expedited basis (e.g., overnight or similarly abbreviated offering period). The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities, one of the Fund’s underwriters, and the underwriting syndicate.

Distribution Through Privately Negotiated Transactions

The Fund, through Nuveen Securities, from time to time may sell directly to, and solicit offers from, institutional and other sophisticated investors, who may be deemed to be underwriters as defined in the 1933 Act for any resale of Common Shares.

The principal business address of Nuveen Securities is 333 West Wacker Drive, Chicago, Illinois 60606.

DESCRIPTION OF SHARES

Common Shares

The Declaration authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to the rights of holders of preferred shares, if issued, and borrowings, if incurred, have equal rights to the payment of dividends and the distribution of assets upon liquidation. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed in “Certain Provisions in the Declaration of Trust,” non-assessable, and will have no pre-emptive or conversion rights or rights to cumulative voting. Each Common Share has one vote with respect to matters upon which a shareholder vote is required, consistent with the requirements of the 1940 Act and the rules promulgated thereunder, and will vote together as a single class. Whenever the Fund incurs borrowings and/or preferred shares are outstanding, Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all interest on such borrowings has been paid and all accrued dividends on preferred shares have been paid, unless asset coverage (as defined in the 1940 Act) with respect to any borrowings would be at least 300% after giving effect to the distributions and asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to the distributions. See “—Preferred Shares” below.

The Common Shares are listed on the NYSE. The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will not issue share certificates.

Unlike open-end funds, closed-end funds like the Fund do not provide daily redemptions. Rather, if a shareholder determines to buy additional Common Shares or sell shares already held, the shareholder may conveniently do so by trading on the exchange through a broker or otherwise. Shares of closed-end investment companies may frequently trade on an exchange at prices lower than net asset value. Shares of closed-end investment companies like the Fund have during some periods traded at prices higher than net asset value and have during other periods traded at prices lower than net asset value.

Because the market value of the Common Shares may be influenced by such factors as distribution levels (which are in turn affected by expenses), call protection, dividend stability, portfolio credit quality, net asset value, relative demand for and supply of such shares in the market, general market and economic conditions, and other factors beyond the control of the Fund, the Fund cannot assure you that Common Shares will trade at a price equal to or higher than net asset value in the future. The Common Shares are designed primarily for long-term investors, and investors in the Common Shares should not view the Fund as a vehicle for trading purposes. See “Repurchase of Fund Shares; Conversion to Open-End Fund.”

Borrowings

The Declaration authorizes the Fund, without approval of the Common Shareholders, to borrow money. In this connection, the Fund may issue notes or other evidence of indebtedness (including bank borrowings or commercial paper) and may secure any such borrowings by mortgaging, pledging or otherwise subjecting as security the Fund’s assets. The Fund expects to borrow money at rates generally available to institutional investors. In connection with such Borrowings, the Fund may be required to maintain minimum average balances with the lender or to pay a commitment or other fee to maintain a line of credit. Any such requirements will increase the cost of any such borrowings over the stated interest rate. Under the requirements of the 1940 Act, the Fund, immediately after any such Borrowings, must have an “asset coverage” of at least 300%. With respect to any such borrowings, asset coverage means the ratio that the value of the total assets of the Fund, less all liabilities and indebtedness not represented by senior securities (as defined in the 1940 Act), bears to the aggregate amount of such borrowings represented by senior securities issued by the Fund. Certain types of borrowings may result in the Fund being subject to covenants in credit agreements relating to asset coverages or portfolio coverages or otherwise. In addition, as with the issuance of preferred shares, certain types of borrowings may result in the Fund being subject to certain restrictions imposed by guidelines of one or more rating agencies that may issue ratings for commercial paper or notes issued by the Fund. Such restrictions may be more stringent than those imposed by the 1940 Act.

The rights of lenders to the Fund to receive interest on and repayment of principal of any such borrowings will be senior to those of the Common Shareholders, and the terms of any such borrowings may contain provisions which limit certain activities of the Fund, including the payment of dividends to Common Shareholders in certain circumstances. Further, the 1940 Act does (in certain circumstances) grant to the lenders to the Fund certain voting rights in the event of default in the payment of interest on or repayment of principal. In the event that such provisions would impair the Fund’s eligibility for treatment as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”), the Fund will attempt to repay or restructure the borrowings to preserve that eligibility. Any borrowings will likely be ranked senior or equal to all other existing and future borrowings of the Fund. The Fund may also borrow up to an additional 5% of its total assets for temporary purposes. The Fund may also borrow money for repurchase of its shares or as a temporary measure for extraordinary or emergency situations. See “Investment Restrictions” in the SAI.

Preferred Shares

Limited Issuance of Preferred Shares. Under the 1940 Act, the Fund could issue preferred shares with an aggregate liquidation value of up to one-half of the value of the Fund’s total net assets, including any liabilities associated with borrowings, measured immediately after issuance of the preferred shares. “Liquidation value” means the original purchase price of the shares being liquidated plus any accrued and unpaid dividends. In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Shares unless the liquidation value of the preferred shares is less than one-half of the value of the Fund’s total net assets (determined after deducting the amount of such dividend or distribution) immediately after the distribution.

Distribution Preference. If issued in the future, the preferred shares would have complete priority over the Common Shares as to distribution of assets.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Fund, holders of preferred shares, if issued in the future, would be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus accumulated and unpaid dividends thereon, whether or not earned or declared) before any distribution of assets is made to Common Shareholders.

Voting Rights. Preferred shares are required to be voting shares and to have equal voting rights with Common Shares. Except as otherwise indicated in this Prospectus or the SAI and except as otherwise required by applicable law, holders of preferred shares, if issued in the future, would vote together with Common Shareholders as a single class.

Holders of preferred shares, if issued in the future, voting as a separate class, would be entitled to elect two of the Fund’s trustees (following the establishment of the Fund by an initial trustee, the Declaration provides for a total of no less than two and no more than 15 trustees). The remaining trustees would be elected by Common Shareholders and holders of preferred shares, if issued in the future, voting together as a single class. In the unlikely event that two full years of accrued dividends are unpaid on the preferred shares, if issued in the future, the holders of all outstanding preferred shares, if issued in the future, voting as a separate class, would be entitled to elect a majority of the Fund’s trustees until all dividends in arrears have been paid or declared and set apart for payment. In order for the Fund to take certain actions or enter into certain transactions, a separate class vote of holders of preferred shares, if issued in the future, would be required, in addition to the single class vote of the holders of preferred shares, if issued in the future, and Common Shares. See “Certain Provisions in the Declaration of Trust” and the SAI under “Description of Shares—Preferred Shares—Voting Rights.”

Redemption, Purchase and Sale of Preferred Shares. The terms of the preferred shares, if issued in the future, would provide that they may be redeemed by the issuer at certain times, in whole or in part, at the original purchase price per share plus accumulated dividends. Any redemption or purchase of preferred shares, if issued in the future, by the Fund will reduce the leverage applicable to Common Shares, while any issuance of shares by the Fund would increase such leverage.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration contains an express disclaimer of shareholder liability for debts or obligations of the Fund and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Declaration further provides for indemnification out of the assets and property of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

Vacancies caused by the death, resignation, retirement, removal or disqualification of a trustee may be filled in any manner that is consistent with the Declaration and applicable law.

required. Approval of shareholders is not required, however, for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization which adversely affects the holders of preferred shares, if issued in the future, the action in question will also require the affirmative vote of the holders of at least two-thirds of the Fund’s preferred shares, if issued in the future, outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, the affirmative vote of the holders of at least a majority of the Fund’s preferred shares, if issued in the future, outstanding at the time, voting as a separate class. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the Common Shares and preferred shares, if issued in the future, voting together as a single class. The votes required to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of preferred shares, if issued in the future, are higher than those required by the 1940 Act. The Board of Trustees is divided into three classes, such a staggered board could delay for up to two years the replacement of a majority of the Board of Trustees. The Board of Trustees believes that the provisions of the Declaration relating to such higher votes are in the best interest of the Fund and its shareholders. See the SAI under “Certain Provisions in the Declaration of Trust.”

The provisions of the Declaration described above could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund’s investment objective and policies. The Board of Trustees of the Fund has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund and its Common Shareholders.

Reference should be made to the Declaration on file with the SEC for the full text of these provisions.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Fund is a closed-end investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Common Shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection, dividend stability, portfolio credit quality, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of closed-end investment companies may frequently trade at prices lower than net asset value, the Fund’s Board of Trustees has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of Common Shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Fund to an open-end investment company. The Fund cannot assure you that its Board of Trustees will decide to take any of these actions, or that share repurchases or tender offers will actually reduce market discount.

If the Fund converted to an open-end investment company, it would be required to redeem all preferred shares then outstanding, if any (requiring in turn that it liquidate a portion of its investment portfolio), and the Common Shares would no longer be listed on the NYSE. In contrast to a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares at any time

(except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less any redemption charge that is in effect at the time of redemption. See the SAI under “Certain Provisions in the Declaration of Trust” for a discussion of the voting requirements applicable to the conversion of the Fund to an open-end investment company.

Before deciding whether to take any action if the Common Shares trade below net asset value, the Board would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund’s portfolio, the impact of any action that might be taken on the Fund or its shareholders, and market considerations. Based on these considerations, even if the Fund’s shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken. See the SAI under “Repurchase of Fund Shares; Conversion to Open-End Fund” for a further discussion of possible action to reduce or eliminate such discount to net asset value. On November 16, 2011, the Fund’s Board of Trustees approved an open market share repurchase program under which the Fund may repurchase up to 10% of its Common Shares. To date, the Fund has not repurchased any Common Shares under the program.

TAX MATTERS

The following information is meant as a general summary for U.S. shareholders. Please see the SAI for additional information. Investors should rely on their own tax adviser for advice about the particular federal, state and local tax consequences to them of investing in the Fund.

The Fund intends to elect to be treated and to qualify each year as a regulated investment company (“RIC”) under Subchapter M of the Code. In order to qualify for treatment as a RIC, the Fund must satisfy certain requirements regarding the sources of its income, the diversification of its assets and the distribution of its income. As a RIC, the Fund is not expected to be subject to federal income tax. The Fund primarily invests in municipal securities (as defined above) issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico or Guam) or municipal securities whose income is otherwise exempt from regular federal income taxes. Substantially all of the Fund’s dividends paid to you are expected to qualify as “exempt-interest dividends.” A shareholder treats an exempt-interest dividend as interest on state and local bonds exempt from regular federal income tax. Federal income tax law imposes an alternative minimum tax with respect to corporations, individuals, trust and estates. Interest on certain municipal securities, such as certain private activity bonds, is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. If the Fund receives income from such municipal securities, a portion of the dividends paid by the Fund, although exempt from regular federal income tax, will be taxable to shareholders whose tax liabilities are determined under the federal alternative minimum tax. The Fund will annually provide a report indicating the percentage of the Fund’s income attributable to municipal securities and the percentage includable in federal alternative minimum taxable income. Corporations are subject to special rules in calculating their federal alternative minimum taxable income with respect to interest from municipal securities.

In addition to exempt-interest dividends, the Fund may also distribute to its shareholders amounts that are treated as long-term capital gain or ordinary income (which may include short-term capital gains). These distributions are generally subject to regular federal income tax, whether or not reinvested in additional shares. Capital gain distributions are generally taxable at rates applicable to long-term capital gains regardless of how long a shareholder has held its shares. Long-term capital gains are currently taxable at a maximum rate of 15%. Absent further legislation, the maximum 15% rate on long-term capital gains will increase to 20% for taxable years beginning after December 31, 2012. The Fund does not expect that any part of its distributions to shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders or as “qualified dividend income,” which for taxable years beginning on or before December 31, 2012 is taxable to noncorporate shareholders at a maximum 15% U.S. federal income tax rate.

For taxable years beginning after December 31, 2012, a 3.8% Medicare contribution tax will generally apply to all or a portion of the net investment income of a shareholder who is an individual and not a nonresident alien

for federal income tax purposes and who has adjusted gross income (subject to certain adjustments) that exceeds a threshold amount ($250,000 if married filing jointly or if considered a “surviving spouse” for federal income tax purposes, $125,000 if married filing separately, and $200,000 in other cases). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts. For these purposes, interest, dividends and certain capital gains are generally taken into account in computing a shareholder’s net investment income, but exempt-interest dividends are not taken into account.

As a regulated investment company, the Fund will not be subject to federal income tax in any taxable year provided that it meets certain distribution requirements. As described in “Distributions” above, the Fund might not distribute some (or all) of its net capital gain. If the Fund retains any net capital gain or taxable net investment income, it will be subject to tax at regular corporate rates on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their shares of such undistributed amount; (ii) will be deemed to have paid their proportionate shares of the tax paid by the Fund on such undistributed amount and will be entitled to credit that amount of tax against their federal income tax liabilities, if any; and (iii) will be entitled to claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of the Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder.

Dividends declared by the Fund in October, November or December, payable to shareholders of record in such a month, and paid during the following January will be treated as having been received by shareholders in the year the distributions were declared.

Each shareholder will receive an annual statement summarizing the shareholder’s dividend and capital gains distributions.

The repurchase, sale or exchange of Common Shares normally will result in capital gain or loss to holders of Common Shares who hold their shares as capital assets. Generally a shareholder’s gain or loss will be long-term capital gain or loss if the shares have been held for more than one year even though the increase in value in such Common Shares may be at least partly attributable to tax-exempt interest income. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For noncorporate taxpayers, however, long-term capital gains are taxed at rates of up to 20%. Short-term capital gains and other ordinary income are taxed to noncorporate shareholders at ordinary income rates. If a shareholder sells or otherwise disposes of Common Shares before holding them for six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the Common Shareholder of long-term capital gain (including any amount credited to the Common Shareholder as undistributed capital gain). Any loss realized on a sale or exchange of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced by substantially identical shares of the Fund (including shares acquired by reason of participation in the Plan) within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares, or to the extent the shareholder enters into a contract or option to repurchase shares within such period. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

Any interest on indebtedness incurred or continued to purchase or carry the Fund’s shares to which exempt-interest dividends are allocated is not deductible. Under certain applicable rules, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of the shares. In addition, if you receive social security or certain railroad retirement benefits, you may be subject to U.S. federal income tax on a portion of such benefits as a result of receiving investment income, including exempt-interest dividends and other distributions paid by the Fund.

The Fund may be required to withhold (as “backup withholding”) U.S. federal income tax from distributions (including exempt-interest dividends) and repurchase proceeds payable to a shareholder if the shareholder fails to provide the Fund with his or her correct taxpayer identification number or to make required certifications, or if the shareholder has been notified by the IRS that he or she is subject to backup withholding. The backup withholding rate is 28%. Backup withholding is not an additional tax; rather, it is a way in which the IRS ensures it will collect taxes otherwise due. Any amounts withheld may be credited against a shareholder’s U.S. federal income tax liability.

USE OF PROCEEDS

The net proceeds from the issuance of Common Shares hereunder will be used by the Fund to invest in municipal securities, in accordance with the Fund’s investment objective and policies as stated below. To the extent the Fund uses the net proceeds of any offering to invest in municipal securities, it is presently anticipated that the ¹Fund will be able to invest substantially all of such proceeds in securities that meet the Fund’s investment objective and policies within one month from the date on which the proceeds from an offering are received by the Fund. Pending such investment, it is anticipated that the proceeds will be invested in short-term or long-term securities issued by the U.S. Government and its agencies or instrumentalities or in high quality, short-term money market instruments. See “Risk Factors—Leverage Risk” and “Use of Leverage” in the Prospectus.

INVESTMENT RESTRICTIONS

Except as described below, the Fund, as a fundamental policy, may not, without the approval of the holders of a majority of the outstanding shares:

(1) Issue senior securities, as defined in the 1940 Act, except as otherwise described in the Prospectus;¹

(2) Borrow money, except as permitted by the 1940 Act and exemptive orders granted under the 1940 Act;^1,²

(3) Act as underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), in connection with the purchase and sale of portfolio securities;

(4) Invest more than 25% of its total assets in securities of issuers in any one industry, provided, however, that such limitation shall not apply to municipal securities other than those municipal securities backed only by the assets and revenues of non-governmental users;³

(5) Purchase or sell real estate, but this shall not prevent the Fund from investing in municipal securities secured by real estate or interests therein or foreclosing upon and selling such real estate;

(6) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts or derivative instruments or from investing in securities or other instruments backed by physical commodities);

(7) Make loans, except as permitted by the 1940 Act and exemptive orders granted under the 1940 Act;⁴

(8) With respect to 75% of the value of the Fund’s total assets, purchase any securities (other than obligations issued or guaranteed by the U.S. government or by its agencies or instrumentalities), if as a

Section 18(c) of the 1940 Act generally limits a registered closed-end investment company to issuing one class of senior securities representing indebtedness and one class of senior securities representing stock, except that the class of indebtedness or stock may be issued in one or more series, and promissory notes or other evidences of indebtedness issued in consideration of any loan, extension, or renewal thereof, made by a bank or other person and privately arranged, and not intended to be publicly distributed, are not deemed a separate class of senior securities.

Section 18(a) of the 1940 Act generally prohibits a registered closed-end fund from incurring borrowings if, immediately thereafter, the aggregate amount of its borrowings exceeds 33¹/₃% of its total assets. The Fund has not applied for, and currently does not intend to apply for, any exemptive relief that would allow it to borrow outside of the limits of the 1940 Act.

³	For purposes of this restriction, governments and their political subdivisions are not members of any industry.

Section 21 of the 1940 Act makes it unlawful for a registered investment company, like the Fund, to lend money or other property if (i) the investment company’s policies set forth in its registration statement do not permit such a loan or (ii) the borrower controls or is under common control with the investment company. The Fund has not applied for, and currently does not intend to apply for, such exemptive relief.

result more than 5% of the Fund’s total assets would then be invested in securities of a single issuer or if as a result the Fund would hold more than 10% of the outstanding voting securities of any single issuer;

(9) Under normal circumstances, invest less than 80% of its Managed Assets in municipal securities and other related investments, the income from which is exempt from regular federal income tax;

(10) Pledge, mortgage or hypothecate its assets, except that, to secure borrowings permitted by subparagraph (2) above, it may pledge securities having a market value at the time of pledge not exceeding 20% of the value of the Fund’s total assets;

(11) Invest more than 10% of its total assets in repurchase agreements maturing in more than seven days;

(12) Purchase or retain the securities of any issuer other than the securities of the Fund if, to the Fund’s knowledge, the trustees of the Fund, or those officers and directors of the Fund’s investment adviser, who individually own beneficially more than 1/2 of 1% of the outstanding securities of such issuer, together own beneficially more than 5% of such outstanding securities; and

(13) Invest more than 20% of its Managed Assets in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals (“AMT Bonds”).

For the purpose of applying the limitation set forth in subparagraph (1) above, the Fund may not issue senior securities not permitted by the 1940 Act simply by describing such securities in the Prospectus.

For the purpose of applying the limitation set forth in paragraph (4) above, such policy will apply to municipal securities if the payment of principal and interest for such securities is derived solely from a specific project, and in that situation the Fund will consider such municipal securities to be in an industry associated with the project.

For the purpose of applying the limitation set forth in subparagraph (8) above, an issuer shall be deemed the sole issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, such as an industrial corporation or a privately owned or operated hospital, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the sole issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal security is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal security will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of the Fund’s assets that may be invested in municipal securities insured by any given insurer.

Under the 1940 Act, the Fund may invest only up to 10% of its Managed Assets in the aggregate in shares of other investment companies and only up to 5% of its Managed Assets in any one investment company, provided the investment does not represent more than 3% of the voting stock of the acquired investment company at the time such shares are purchased. As a stockholder in any investment company, the Fund will bear its ratable share of that investment company’s expenses, and will remain subject to payment of the Fund’s management, advisory and administrative fees with respect to assets so invested. Holders of common shares would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the Prospectus in the section entitled “Risk Factors”, the net asset value and market value of leveraged shares will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

In addition to the foregoing fundamental investment policies, the Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board of Trustees. The Fund may not:

(1) Under normal circumstances, invest less than 80% of its Managed Assets in investment grade securities.

(2) Invest more than 20% of its net assets in municipal securities that at the time of investment are rated below investment grade or are unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management, LLC (“Nuveen Asset Management”), the Fund’s sub-adviser.

(3) Invest more than 10% of its net assets in municipal securities rated below B-/B3 or that are unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management.

(4) Invest more than 10% of its Managed Assets in securities of other open- or closed-end investment companies (including ETFs) that invest primarily in municipal securities of the types in which the Fund may invest directly.

(5) Invest in derivative instruments except in pursuit of its investment objective. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts, or other derivative instruments. Nuveen Asset Management uses derivatives to seek to enhance return, to hedge some of the risks of its investments in fixed income securities or as a substitute for a position in the underlying asset.

(6) Sell securities short, unless the Fund owns or has the right to obtain securities equivalent in kind and amount to the securities sold at no added cost, and provided that transactions in options, futures contracts, options on futures contracts, or other derivative instruments are not deemed to constitute selling securities short.

(7) Enter into futures contracts or related options or forward contracts, if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on futures contracts and related options.

The restrictions and other limitations set forth above will apply only at the time of purchase of securities and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities.

Investment grade quality securities are those that are, at the time of investment, either (i) rated by one of the NRSROs that rate such securities within the four highest letter grades (including BBB or Baa or better by Standard & Poor’s Corporation Ratings Group, a division of The McGraw-Hill Companies (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) or Fitch Ratings, Inc. (“Fitch”)), or (ii) unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management. Investment grade securities may include split-rated securities.

The Fund may be subject to certain restrictions imposed by either guidelines of one or more NRSROs that may issue ratings for preferred shares, if any, commercial paper or notes, or, if the Fund borrows from a lender, by the lender. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. If these restrictions were to apply, it is not anticipated that these covenants or guidelines would impede Nuveen Asset Management from managing the Fund’s portfolio in accordance with the Fund’s investment objective and policies.

INVESTMENT POLICIES AND TECHNIQUES

The following information supplements the discussion of the Fund’s investment objective, policies, and techniques that are described in the Prospectus.

INVESTMENT OBJECTIVE

INVESTMENT PHILOSOPHY AND PROCESS

INVESTMENT PHILOSOPHY. Nuveen Asset Management believes that the unique tax treatment of municipal securities and the structural characteristics in the municipal securities market create attractive opportunities to enhance the after-tax total return and diversification of the investment portfolios of taxable investors. Nuveen Asset Management believes that these unique characteristics also present unique risks that may be managed to realize the benefits of the asset class. Nuveen Asset Management considers the following factors:

INVESTMENT PROCESS. Nuveen Asset Management believes that a bottom-up, research-driven investment strategy that seeks to identify underrated and undervalued securities and sectors is positioned to capture the opportunities inherent in the municipal securities market and potentially outperform the general municipal securities market over time. The primary elements of Nuveen Asset Management’s investment process are:

Credit Analysis and Surveillance. Nuveen Asset Management focuses on bottom-up, fundamental analysis of municipal securities issuers. Analysts screen each sector for issuers that meet the fundamental tests of creditworthiness and favor those securities with demonstrable growth potential, solid coverage of debt service and a priority lien on hard assets, dedicated revenue streams or tax resources. As part of Nuveen Asset Management’s overall risk management process, analysts actively monitor the credit quality of portfolio holdings.

INVESTMENT POLICIES

As a non-fundamental policy, the Fund seeks to achieve its investment objective by investing in a diversified portfolio of municipal securities at least 80% comprised of investment grade quality securities, the income from which is exempt from regular federal income tax. Nuveen Asset Management seeks to identify and invest in municipal securities that it believes are underrated and undervalued. Nuveen Asset Management believes its value oriented strategy offers the opportunity to construct a well-diversified portfolio of municipal securities that has the potential to outperform major municipal market benchmarks over the longer term. Underrated municipal securities are those whose ratings do not, in Nuveen Asset Management’s opinion, reflect their true creditworthiness. Undervalued municipal securities are securities that, in Nuveen Asset Management’s opinion, are worth more than the value assigned to them in the marketplace. A municipal security’s market value generally will depend upon its form, maturity, call features, and interest rate, as well as the issuer’s credit quality or credit rating, all such factors examined in the context of the municipal securities market and interest rate levels and trends. Nuveen Asset Management may at times believe that securities associated with a particular municipal market sector (for example, electric utilities), or issued by a particular municipal issuer, are undervalued. Nuveen Asset Management may purchase such a security for the Fund’s portfolio because it represents a market sector or issuer that Nuveen Asset Management considers undervalued, even if the value of the particular security appears to be consistent with the value of similar securities. Municipal securities of particular types (e.g., hospital bonds, industrial revenue bonds or securities issued by a particular municipal issuer) may be undervalued because there is a temporary excess of supply in that market sector, or because of a general decline in the market price of municipal securities of the market sector for reasons that do not apply to the particular municipal securities that are considered undervalued. A rating issued by an NRSRO is only the opinion of the entity issuing the rating, and is not a guarantee as to quality, or an assurance of the performance, of the rated security. In addition, the manner in which NRSROs obtain and process information about a particular security may affect the NRSRO’s ability to timely react to changes in an issuer’s circumstances that could influence a particular rating. The Fund’s investment in underrated or undervalued municipal securities will be based on Nuveen Asset Management’s belief that their yield is higher than that available on securities bearing equivalent levels of interest rate risk, credit risk and other forms of risk, and that their prices will ultimately rise (relative to the market) to reflect their

true value. The Fund attempts to increase its portfolio value relative to the municipal bond market by prudent selection of municipal securities regardless of the direction the market may move. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to Common Shareholders.

As of April , 2013, approximately % of the Fund’s Managed Assets were invested in securities rated investment grade by an NRSRO (including S&P, Moody’s or Fitch). The relative percentages of the value of the investments attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund’s assets by Nuveen Asset Management, market value fluctuations, issuance of additional shares and other events.

The Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income tax. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects, such as roads, schools, and water supply systems. Municipal securities also may be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility or pollution control projects. Municipal securities may be issued on a long-term basis to provide long-term financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments, and mortgage payments. Municipal securities also may be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms that include fixed coupon, variable rate or zero coupon, including capital appreciation bonds, floating rate securities, and inverse floating rate securities. Such municipal securities may also be acquired through investments in pooled vehicles, partnerships, or other investment companies. The Fund may invest in these types of securities, including floating rate securities and inverse floating rate securities, in order to more efficiently achieve its desired overall portfolio structure as well as enhance its ability to achieve its investment objective.

The Fund intends to use leverage to seek to enhance its potential for current income exempt from regular federal income tax. The Fund intends to use leverage by investing in inverse floating rate securities that have the economic effect of leverage, as discussed further below. The Fund may leverage its capital structure by issuing senior securities such as preferred shares, investing in debt securities or by borrowing. The combined economic effect of the total leverage used by the Fund is referred to as “effective leverage.” The Fund currently uses leverage by investing in inverse floating rate securities. If current market conditions change (for example, if there is a material decrease in the supply of inverse floating rate securities or if newly issued senior securities become a more attractive financing option), the Fund may use other forms of leverage. Financial leverage is created as a result of the Fund’s investments in residual interest certificates of tender option bond trusts, also called inverse floating rate securities, because the Fund’s investment exposure to the underlying bonds held by the trust have been effectively financed by the trust’s issuance of floating rate certificates. As of , 2013, the Fund’s total effective leverage was approximately % of its Managed Assets.

There can be no assurance that the Fund’s leverage strategy will be successful. The use of leverage creates special risks for Common Shareholders. See the Prospectus under “Use of Leverage,” “Risk Factors—Leverage Risk” and “ Risk Factors—Inverse Floating Rate Securities Risk.”

assets would be committed to initial margin deposits and premiums on futures contracts and related options. Nuveen Asset Management uses derivatives to seek to enhance return, to hedge some of the risks of its investments in fixed income securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income. See “Hedging Strategies and Other Uses of Derivatives” herein.

Under normal circumstances:

•

As a non-fundamental policy, the Fund will invest at least 80% of its Managed Assets in municipal securities and other related investments that at the time of investment are investment grade quality. A municipal security is considered investment grade quality if it is rated within the four highest letter grades (BBB or Baa or better) by at least one of the NRSROs that rate such security (even if it is rated lower by another), or if it is unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management.

•

As a non-fundamental policy, the Fund may invest up to 20% of its Managed Assets in municipal securities rated below investment grade or are unrated by any NRSRO but judged to be of comparable quality by Nuveen Asset Management. Additionally, as a non-fundamental policy, no more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Asset Management. Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds. See the Prospectus under “Risk Factors—Credit and Below Investment Grade Risk.”

•

The Fund will not invest more than 25% of its Managed Assets in municipal securities in any one industry or in any one state of origin and no more than 5% of its Managed Assets in any one issuer.

Any non-fundamental policy of the Fund may be changed by the Fund’s Board following the provision of 60 days prior written notice to Common Shareholders.

The credit quality policies noted above apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, Nuveen Asset Management may consider such factors as Nuveen Asset Management’s assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. A general description of the ratings of S&P, Moody’s and Fitch of municipal securities is set forth in Appendix A to this SAI.

Municipal securities may also be issued on behalf of or for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source; revenue bonds may be repaid only from the revenues of a specific facility or source. The Fund may also purchase municipal securities that represent lease obligations, municipal notes, pre-refunded municipal securities, private activity bonds, tender option bonds and other related securities and derivative instruments that create exposure to municipal bonds, notes and securities and that provide for the payment of interest income that is exempt from regular federal income tax.

Municipal securities of below investment grade quality (Ba/BB or below) are commonly referred to as junk bonds. Issuers of securities rated Ba/BB or B are regarded as having current capacity to make principal and interest payments but are subject to business, financial or economic conditions which could adversely affect such payment capacity. Municipal securities rated Baa or BBB are considered “investment grade” securities; municipal securities rated Baa are considered medium grade obligations which lack outstanding investment characteristics and have speculative characteristics, while municipal securities rated BBB are regarded as having adequate capacity to pay principal and interest. Municipal securities rated Aaa or AAA in which the Fund may invest may have been so rated on the basis of the existence of insurance guaranteeing the timely payment, when due, of all principal and interest. Municipal securities rated below investment grade quality are obligations of issuers that are considered predominately speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Municipal securities rated below investment grade tend to be less marketable than higher-quality securities because the market for them is less broad. The market for unrated municipal securities is even narrower. During periods of thin trading in these markets, the spread between bid and asked prices is likely to increase significantly and the Fund may have greater difficulty selling its portfolio securities. The Fund will be more dependent on Nuveen Asset Management’s research and analysis when investing in these securities.

A general description of Moody’s, S&P’s and Fitch’s ratings of municipal securities is set forth in Appendix A hereto. The ratings of Moody’s, S&P and Fitch represent their opinions as to the quality of the municipal securities they rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield.

The Fund will primarily invest in municipal securities with intermediate or long-term, but the weighted average maturity of obligations held by the Fund may be shorter, depending on market conditions. As a result, the Fund’s portfolio at any given time may include both long-term and intermediate-term municipal securities. Moreover, during temporary defensive periods (e.g., times when, in Nuveen Asset Management’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt securities market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to keep the Fund’s cash fully invested, including the period during which the net proceeds of an offering are being invested, the Fund may invest any percentage of its net assets in short-term investments including high quality, short-term securities that may be either tax-exempt or taxable and up to 10% of its Managed Assets in securities of other open or closed-end investment companies that invest primarily in municipal securities of the type in which the Fund may invest directly. The Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Tax-exempt short-term investments include various obligations issued by state and local governmental issuers, such as tax-exempt notes (bond anticipation notes, tax anticipation notes and revenue anticipation notes or other such municipal bonds maturing in three years or less from the date of issuance) and municipal commercial paper. The Fund will invest only in taxable short-term investments which are U.S. government securities or securities rated within the highest grade by Moody’s, S&P or Fitch, and which mature within one year from the date of purchase or carry a variable or floating rate of interest. See Appendix A for a general description of Moody’s, S&P’s and Fitch’s ratings of securities in such categories. Taxable short-term investments of the Fund may include certificates of deposit issued by U.S. banks with assets of at least $1 billion, or commercial paper or corporate notes, bonds or debentures with a remaining maturity of one year or less, or repurchase agreements. See “Investment Policies and Techniques.” To the extent the Fund invests in taxable investments, the Fund will not at such times be in a position to achieve its investment objective of tax-exempt income.

The foregoing policies as to ratings of portfolio investments will apply only at the time of the purchase of a security, and the Fund will not be required to dispose of securities in the event Moody’s, S&P or Fitch downgrades its assessment of the credit characteristics of a particular issuer.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Bankruptcy Reform Act of 1978. In addition, the obligations of such issuers may become subject to the laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal securities may be materially affected.

Subject to rating agency guidelines, the Fund may invest a significant portion of its Managed Assets in broad segments of the municipal securities market, such as revenue obligations of hospitals and other health care facilities, special taxing districts, securities issued to finance charter schools and other private educational facilities, municipal utility securities, industrial development bonds and other private activity bonds. Subject to the availability of suitable investment opportunities, Nuveen Fund Advisors, LLC, the Fund’s investment adviser (“NFALLC”) will attempt to minimize the sensitivity of the Fund’s portfolio to credit and other risks associated with a particular sector or industry. However, if the Fund invests a significant portion of its Managed Assets in the segments noted above, the Fund will be more susceptible to economic, business, political, regulatory and other developments generally affecting issuers in such segments of the municipal securities market. To the extent that the Fund focuses its Managed Assets in the hospital and healthcare facilities sector, the Fund will be subject to risks associated with such sector, including adverse government regulation and reduction in reimbursement rates, as well as government approval of products and services and intense competition. Securities issued to finance charter schools and other private educational facilities will be subject to various risks, including the reversal of legislation authorizing or funding charter schools, the failure to renew or secure a charter, the failure of a funding entity to appropriate necessary funds and competition from alternatives such as voucher programs. Issuers of municipal utility securities can be significantly affected by government regulation, financing difficulties, supply and demand of services or fuel and natural resource conservation.

Upon NFALLC’s recommendation, during temporary defensive periods and in order to keep the Fund’s cash fully invested, including the period during which the net proceeds of an offering of common shares or preferred shares are being invested, the Fund may deviate from its investment objective and invest up to 100% of its Managed Assets in short-term investments including high quality, short-term securities that may be either tax-exempt or taxable. To the extent the Fund invests in taxable short-term investments, the Fund will not at such times be in a position to achieve that portion of its investment objective of seeking current income exempt from regular federal income tax. For further information, see “Short-Term Investments” below.

General. The Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income tax. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility and pollution control projects. Municipal securities may be issued on a long term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms including fixed coupon, variable rate, zero coupon, capital appreciation bonds, tender option bonds, and residual interest bonds or inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships or other investment companies. Inverse floating rate securities are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and represent a leveraged investment in an underlying municipal security, which could have the economic effect of financial leverage.

Municipal Leases and Certificates of Participation. Also included within the general category of municipal securities described in the Prospectus are municipal leases, certificates of participation in such lease obligations or installment purchase contract obligations (hereinafter collectively called “Municipal Lease Obligations”) of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality’s taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain “non-appropriation” clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a “non-appropriation” lease, the Fund’s ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and disposition or releasing of the property might prove difficult. In order to reduce this risk, the Fund will only purchase Municipal Lease Obligations where Nuveen Asset Management believes the issuer has a strong incentive to continue making appropriations until maturity.

funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Tender Option Bonds. A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term, tax-exempt rates. The bond is typically issued with the agreement of a third party, such as a bank, broker-dealer or other financial institution, which grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the bond’s fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, an institution will not be obligated to accept tendered bonds in the event of certain defaults or a significant downgrade in the credit rating assigned to the issuer of the bond. The Fund intends to invest in tender option bonds the interest on which will, in the opinion of bond counsel, counsel for the issuer of interests therein or counsel selected by Nuveen Asset Management, be exempt from regular federal income tax. However, because there can be no assurance that the Internal Revenue Service (“IRS”) will agree with such counsel’s opinion in any particular case, there is a risk that the Fund will not be considered the owner of such tender option bonds and thus will not be entitled to treat such interest as exempt from such tax. Additionally, the federal income tax treatment of certain other aspects of these investments, including the proper tax treatment of tender option bonds and the associated fees in relation to various regulated investment company tax provisions, is unclear. The Fund intends to manage its portfolio in a manner designed to eliminate or minimize any adverse impact from the tax rules applicable to these investments.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure development to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

HEDGING STRATEGIES AND OTHER USES OF DERIVATIVES

The Fund may periodically engage in hedging transactions, and otherwise use various types of derivative instruments, described below, to reduce risk, to effectively gain particular market exposures, to seek to enhance returns, and to reduce transaction costs, among other reasons.

“Hedging” is a term used for various methods of seeking to preserve portfolio capital value by offsetting price changes in one investment through making another investment whose price should tend to move in the opposite direction.

A “derivative” is a financial contract whose value is based on (or “derived” from) a traditional security (such as a stock or a bond), an asset (such as a commodity like gold), or a market index (such as the Lehman Municipal Bond Index). Some forms of derivatives may trade on exchanges, while non-standardized derivatives, which tend to be more specialized and complex, trade in “over-the-counter” or a one-on-one basis. It may be desirable and possible in various market environments to partially hedge the portfolio against fluctuations in market value due to market interest rate or credit quality fluctuations, or instead to gain a desired investment exposure, by entering into various types of derivative transactions, including financial futures and index futures as well as related put and call options on such instruments, structured notes, or interest rate swaps on taxable or tax-exempt securities or indexes (which may be “forward-starting”), credit default swaps, and options on interest rate swaps, among others.

These transactions present certain risks. In particular, the imperfect correlation between price movements in the futures contract and price movements in the securities being hedged creates the possibility that losses on the hedge by the Fund may be greater than gains in the value of the securities in the Fund’s portfolio. In addition, futures and options markets may not be liquid in all circumstances. As a result, in volatile markets, the Fund may not be able to close out the transaction without incurring losses substantially greater than the initial deposit. Finally, the potential deposit requirements in futures contracts create an ongoing greater potential financial risk than do options transactions, where the exposure is limited to the cost of the initial premium. Losses due to hedging transactions will reduce yield. Net gains, if any, from hedging and other portfolio transactions will be distributed as taxable distributions to shareholders. Successful implementation of most hedging strategies will generate taxable income.

Swap Transactions. The Fund may enter into total return, interest rate and credit default swap agreements and interest rate caps, floors and collars. The Fund may also enter into options on the foregoing types of swap agreements (“swap options”).

The Fund may enter into swap transactions for any purpose consistent with its investment objective, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, as a duration management technique, to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain sectors or markets in the most economical way possible.

Swap agreements are two party contracts entered into primarily by institutional investors for a specified period of time. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a particular predetermined asset, reference rate or index. The gross returns to be exchanged or swapped between the parties are generally calculated with respect to a notional amount, e.g., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a basket of securities representing a particular index. The notional amount of the swap agreement generally is only used as a basis upon which to calculate the obligations that the parties to the swap agreement have agreed to exchange. The Fund’s current obligations under a net swap agreement will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by assets determined to be liquid by Nuveen Asset Management. See “—Segregation of Assets” below.

Some, but not all, swaps may be cleared, in which case a central clearing counterparty stands between each buyer and seller and effectively guarantees performance of each contract, to the extent of its available resources for such purpose. Uncleared swaps have no such protection; each party bears the risk that its direct counterparty will default.

Interest Rate Swaps, Caps, Collars and Floors. Interest rate swaps are bilateral contracts in which each party agrees to make periodic payments to the other party based on different referenced interest rates (e.g., a fixed rate and a floating rate) applied to a specified notional amount. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index rises above a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. Interest rate collars involve selling a cap and purchasing a floor or vice versa to protect the Fund against interest rate movements exceeding given minimum or maximum levels.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely-diversified range of securities in a single trade. An index total return swap can be used by Nuveen Asset Management to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. The Fund may enter into credit default swap agreements either as a buyer or a seller. The Fund may buy protection to attempt to mitigate the risk of default or credit quality deterioration in an individual security or a segment of the fixed income securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Fund may sell protection in an attempt to gain exposure to the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments.

As the buyer of protection in a credit default swap, the Fund would pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

If the Fund is a seller of protection in a credit default swap and no credit event occurs, the Fund would generally receive an up-front payment or a periodic stream of payments over the term of the swap. If a credit event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Fund effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. Thus, the Fund bears the same risk as it would by buying the reference obligations directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “—Risks Associated with Swap Transactions.”

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. The Fund may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Fund generally would incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund would become obligated according to the terms of the underlying agreement.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If Nuveen Asset Management is incorrect in its forecasts of default risks, market spreads or other applicable factors or events, the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, the Fund effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The Fund generally may only close out a swap, cap, floor, collar or other two-party contract with its particular counterparty, and generally may only transfer a position with the consent of that counterparty. In addition, the price at which the Fund may close out such a two party contract may not correlate with the price change in the underlying reference asset. If the counterparty defaults, the Fund will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Fund will succeed in enforcing its rights. It also is possible that developments in the derivatives market, including changes in government regulation, could adversely affect the Fund’s ability to terminate existing swap or other agreements or to realize amounts to be received under such agreements.

Futures and Options on Futures. A futures contract is an agreement between two parties to buy and sell a security, index or interest rate (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract (same exchange, underlying financial instrument, and delivery month). Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the futures broker, known as a futures commission merchant (“FCM”), an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to

ensure completion of the contract. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, FCMs may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin account generally is not income producing. However, couponbearing securities, such as Treasury securities, held in margin accounts generally will earn income. Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the Fund as unrealized gains or losses. At any time prior to expiration of the futures contract, the Fund may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the Fund, the Fund may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Fund. Futures transactions also involve brokerage costs and the Fund may have to segregate additional liquid assets in accordance with applicable SEC requirements. See “—Segregation of Assets” below.

A futures option gives the purchaser of such option the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the purchaser acquires a long position in the futures contract and the writer is assigned the opposite short position. Upon the exercise of a put option, the opposite is true.

Limitations on the Use of Futures, Futures Options and Swaps. Pursuant to a claim for exemption filed with the National Futures Association on behalf of the Fund, the Fund is not deemed to be a commodity pool operator or a commodity pool under the Commodity Exchange Act (“CEA”) and neither it nor NFALLC or Nuveen Asset Management is currently subject to registration or regulation as such under the CEA with respect to the Fund. In February 2012, the Commodity Futures Trading Commission (“CFTC”) announced substantial amendments to certain exemptions, and to the conditions for reliance on those exemptions, from registration as a commodity pool operator. Under amendments to the exemption provided under CFTC Regulation 4.5, if the Fund uses futures, options on futures, or swaps other than for bona fide hedging purposes (as defined by the CFTC), the aggregate initial margin and premiums on these positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are “in-the-money” at the time of purchase are “in-the-money”) may not exceed 5% of the Fund’s net asset value, or alternatively, the aggregate net notional value of those positions may not exceed 100% of the Fund’s net asset value (after taking into account unrealized profits and unrealized losses on any such positions). The CFTC amendments to Regulation 4.5 went into effect December 31, 2012 and the Fund intends to comply with amended Regulation 4.5’s requirements such that NFALLC and/or Nuveen Asset Management will not be required to register with respect to the Fund as a commodity pool operator with the CFTC. The Fund reserves the right to engage in transactions involving futures, options thereon and swaps to the extent allowed by CFTC regulations in effect from time to time and in accordance with the Fund’s policies. The requirements for qualification as a regulated investment company may limit the extent to which the Fund may enter into futures transactions, engage in options transactions or engage in swap transactions.

NFALLC may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income.

There is no assurance that these derivative strategies will be available at any time or that NFALLC will determine to use them for the Fund or, if used, that the strategies will be successful.

For further information regarding these investment strategies and risks presented thereby, see Appendix B to this SAI.

ILLIQUID SECURITIES

The Fund will not invest more than 15% of its Managed Assets in municipal securities that, at the time of investment, are illiquid (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the Securities Act that are deemed to be illiquid, and certain repurchase agreements.

Restricted securities may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the Securities Act. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than that which prevailed when it decided to sell. To the extent that the Board of Trustees or its delegatee determines that the price of any illiquid security provided by the pricing service is inappropriate, such security will be priced at a fair value as determined in good faith by the Board of Trustees or its delegatee.

INVERSE FLOATING RATE SECURITIES AND FLOATING RATE SECURITIES

Inverse Floating Rate Securities. The Fund may invest up to approximately 15% of its Managed Assets in inverse floating rate securities. Inverse floating rate securities (sometimes referred to as “inverse floaters”) are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust formed by a third party sponsor for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees. The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, the institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, the Fund receives the residual cash flow from the special purpose trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security, the Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal security deposited into the special purpose trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the total face value of the short-term floaters in relation to the value of the residual inverse floaters that are issued by the special purpose trust. The Fund expects to make limited investments in inverse floaters, with leverage ratios that may vary at inception between one and three times. In addition, all voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to the Fund, as the holder of the residual inverse floating rate securities.

environment (i.e., when bond values are falling), but tend to outperform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity based upon, among other things, the liquidity of the underlying securities deposited in a special purpose trust.

The Fund may invest in inverse floating rate securities, issued by special purpose trusts that have recourse to the Fund. In Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party sponsor of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party sponsor of such inverse floater, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. Such agreements may expose the Fund to a risk of loss that exceeds its investment in the inverse floating rate securities. The Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts. Absent a shortfall and forbearance agreement, the Fund would not be required to make such a reimbursement. If the Fund chooses not to enter into such an agreement, the special purpose trust could be liquidated and the Fund could incur a loss. See also “Segregation of Assets” in this SAI.

The Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same special purpose trust.

Investments in inverse floating rate securities have the economic effect of leverage. The use of leverage creates special risks for Common Shareholders. See the Prospectus under “Use of Leverage,” “Risk Factors—Leverage Risk,” and “Risk Factors—Inverse Floating Rate Securities Risk.”

Floating Rate Securities. The Fund may also invest in floating rate securities, as described above, issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.

OTHER INVESTMENT COMPANIES

The Fund may invest up to 10% of its Managed Assets in securities of other open or closed-end investment companies (including exchange-traded funds (“ETFs”)) that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, the Fund may invest a portion of its Managed Assets in pooled investment vehicles (other than investment companies) that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund generally expects that it may invest in other investment companies and/or other pooled investment vehicles either during periods when it has large amounts of uninvested cash, such as the period shortly after the Fund receives the proceeds of an offering of its Common Shares or borrowing or during periods when there is a shortage of attractive, high-yielding municipal securities available in

the market. The Fund may invest in investment companies that are advised by NFALLC, Nuveen Asset Management or their respective affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management, advisory and administrative fees with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. NFALLC will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the Prospectus, the net asset value and market value of leveraged shares will be more volatile and the yield to Common Shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

PORTFOLIO TRADING AND TURNOVER RATE

REPURCHASE AGREEMENTS

As temporary investments, the Fund may invest in repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities (U.S. government securities or municipal securities) agrees to repurchase the same security at a specified price on a future date agreed upon by the parties. The agreed-upon repurchase price determines the yield during the Fund’s holding period. Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. Income generated from transactions in repurchase agreements will be taxable. See “Tax Matters” for information relating to the allocation of taxable income between common shares and preferred shares, if any. The Fund will only enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of NFALLC, present minimal credit risk. The risk to the Fund is limited to the ability of the issuer to pay the agreed-upon repurchase price on the delivery date; however, although the value of the underlying collateral at the time the transaction is entered into always equals or exceeds the agreed-upon repurchase price, if the value of the collateral declines there is a risk of loss of both principal and interest. In the event of default, the collateral may be sold but the Fund might incur a loss if the value of the collateral declines, and might incur disposition costs or experience delays in connection with liquidating the collateral. In addition, if bankruptcy proceedings are commenced with respect to the seller of the security, realization upon the collateral by the Fund may be delayed or limited. Nuveen Asset Management will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the repurchase agreement in an effort to determine that such value always equals or exceeds the agreed-upon repurchase price. In the event the value of the collateral

declines below the repurchase price, Nuveen Asset Management will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

SEGREGATION OF ASSETS

As a closed-end investment company registered with the SEC, the Fund is subject to the federal securities laws, including the 1940 Act, the rules thereunder, and various interpretive provisions of the SEC and its staff. In accordance with these laws, rules and positions, the Fund must “set aside” (often referred to as “asset segregation”) liquid assets, or engage in other SEC or staff-approved measures, to “cover” open positions with respect to certain kinds of derivatives instruments. In the case of forward currency contracts that are not contractually required to cash settle, for example, the Fund must set aside liquid assets equal to such contracts’ full notional value while the positions are open. With respect to forward currency contracts that are contractually required to cash settle, however, the Fund is permitted to set aside liquid assets in an amount equal to the Fund’s daily marked-to-market net obligations (i.e., the Fund’s daily net liability) under the contracts, if any, rather than such contracts’ full notional value. The Fund reserves the right to modify its asset segregation policies in the future to comply with any changes in the positions from time to time articulated by the SEC or its staff regarding asset segregation.

To the extent that the Fund uses its assets to cover its obligations as required by the 1940 Act, the rules thereunder, and applicable positions of the SEC and its staff, such assets may not be used for other operational purposes. NFALLC will monitor the Fund’s use of derivatives and will take action as necessary for the purpose of complying with the asset segregation policy stated above. Such actions may include the sale of the Fund’s portfolio investments.

SHORT-TERM INVESTMENTS

Short-Term Taxable Fixed Income Securities

For temporary defensive purposes or to keep cash on hand fully invested, the Fund may invest up to 100% of its net assets in cash equivalents and short- term taxable fixed-income securities, although the Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short- term investments are not available at reasonable prices and yields. Short-term taxable fixed income investments are defined to include, without limitation, the following:

(1) U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks,¹ Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association,¹ whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies, and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

(2) Certificates of Deposit issued against funds deposited in a bank or a savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. The

¹	These securities are not backed by the full faith and credit of the United States Government.

issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current FDIC regulations, the maximum insurance payable as to any one certificate of deposit is $100,000; therefore, certificates of deposit purchased by the Fund may not be fully insured.

(3) Repurchase agreements, which involve purchases of debt securities. At the time the Fund purchases securities pursuant to a repurchase agreement, it simultaneously agrees to resell and redeliver such securities to the seller, who also simultaneously agrees to buy back the securities at a fixed price and time. This assures a predetermined yield for the Fund during its holding period, since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to obligations of the U.S. government, its agencies or instrumentalities; certificates of deposit; or bankers’ acceptances in which the Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. Nuveen Asset Management monitors the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. Nuveen Asset Management does so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(4) Commercial paper, which consists of short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for such notes. However, they are redeemable by the Fund at any time. Nuveen Asset Management will consider the financial condition of the corporation (e.g., earning power, cash flow, and other liquidity measures) and will continuously monitor the corporation’s ability to meet all of its financial obligations, because the Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. Investments in commercial paper will be limited to commercial paper rated in the highest categories by a major rating agency and which mature within one year of the date of purchase or carry a variable or floating rate of interest.

Short-Term Tax-Exempt Municipal Securities

Short-term tax-exempt municipal securities are securities that are exempt from regular federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt municipal income securities are defined to include, without limitation, the following:

Bond Anticipation Notes (“BANs”) are usually general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer’s access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.

Tax Anticipation Notes (“TANs”) are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. TANs are usually general obligations of the issuer. A weakness in an issuer’s capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer’s ability to meet its obligations on outstanding TANs.

Revenue Anticipation Notes (“RANs”) are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer’s ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.

Construction Loan Notes are issued to provide construction financing for specific projects. Frequently, these notes are redeemed with funds obtained from the Federal Housing Administration. Bank Notes are notes issued by local government bodies and agencies, such as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied but they are frequently issued to meet short-term working capital or capital-project needs. These notes may have risks similar to the risks associated with TANs and RANs.

Tax-Exempt Commercial Paper (“Municipal Paper”) represents very short-term unsecured, negotiable promissory notes issued by states, municipalities and their agencies. Payment of principal and interest on issues of municipal paper may be made from various sources, to the extent the funds are available therefrom. Maturities of municipal paper generally will be shorter than the maturities of TANs, BANs or RANs. There is a limited secondary market for issues of Municipal Paper.

Certain municipal securities may carry variable or floating rates of interest whereby the rate of interest is not fixed but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

While the various types of notes described above as a group represent the major portion of the short-term tax-exempt note market, other types of notes are available in the marketplace and the Fund may invest in such other types of notes to the extent permitted under its investment objective, policies and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15-45 days of the trade date. On such transactions the payment obligation and the interest rate are fixed at the time the buyer enters into the commitment. Beginning on the date the Fund enters into a commitment to purchase securities on a when-issued or delayed delivery basis, the Fund is required under rules of the Commission to maintain in a separate account liquid assets, consisting of cash, cash equivalents or liquid securities having a market value, at all times, of at least equal to the amount of the commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund. The Fund may enter into contracts to purchase municipal securities on a forward basis (i.e., where settlement will occur more than 60 days from the date of the transaction) only to the extent that the Fund specifically collateralizes such obligations with a security that is expected to be called or mature within sixty days before or after the settlement date of the forward transaction. The commitment to purchase securities on a when-issued, delayed delivery or forward basis may involve an element of risk because no interest accrues on the bonds prior to settlement and at the time of delivery the market value may be less than cost.

ZERO COUPON BONDS

A zero coupon bond is a bond that typically does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, the holder receives the par value of the zero coupon bond, which generates a return equal to the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. This

original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon securities and other OID instruments do not pay cash interest at regular intervals, the instruments’ ongoing accruals require ongoing judgments concerning the collectability of deferred payments and the value of any associated collateral. As a result, these securities may be subject to greater value fluctuations and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash on a current basis. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Fund generally will be required to distribute dividends to shareholders representing the income of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

The management of the Fund, including general supervision of the duties performed for the Fund under the Investment Management Agreement with NFALLC (as defined under “Investment Adviser, Sub-Adviser and Portfolio Manager—Investment Management Agreement and Related Fees”), is the responsibility of the Board of Trustees of the Fund. The number of trustees of the Fund is ten, one of whom is an “interested person” (as the term “interested person” is defined in the 1940 Act) and nine of whom are not interested persons (referred to herein as “independent trustees”). None of the independent trustees has ever been a director, trustee or employee of, or consultant to, Nuveen Investments Inc. (“Nuveen Investments”), NFALLC, Nuveen Asset Management or their affiliates. The Board of Trustees is divided into three classes, Class I, Class II and Class III, the Class I trustees serving until the 2013 annual meeting, the Class II trustees serving until the 2014 annual meeting and the Class III trustees serving until the 2015 annual meeting, in each case until their respective successors are elected and qualified, as described below. Currently, William C. Hunter, Judith M. Stockdale, Carole E. Stone and Virginia L. Stringer are slated in Class I, John P. Amboian, David J. Kundert and Terence J. Toth are slated in Class II and Robert P. Bremner, Jack B. Evans and William J. Schneider are slated in Class III. The officers of the Fund serve annual terms and are elected on an annual basis. The names, business addresses and birthdates of the trustees and officers of the Fund, their principal occupations and other affiliations during the past five years, the number of portfolios each oversees and other trusteeships they hold are set forth below. The Trustees of the Fund are directors or trustees, as the case may be, of 101 Nuveen-sponsored open-end funds (the “Nuveen Mutual Funds”) and 105 Nuveen-sponsored closed-end funds (collectively with the Nuveen Mutual Funds, the “Nuveen Funds”).

Board Leadership Structure and Risk Oversight

The Board of Directors or the Board of Trustees (as the case may be, each is referred to hereafter as the “Board” and the directors or trustees of the Nuveen Funds, as applicable, are each referred to herein as “Trustees”) oversees the operations and management of the Nuveen Funds, including the duties performed for the Nuveen Funds by NFALLC and each fund’s sub-adviser, as applicable. The Board has adopted a unitary board structure. A unitary board consists of one group of trustees who serve on the board of every fund in the complex. In adopting a unitary board structure, the Trustees seek to provide effective governance through establishing a board, the overall composition of which, will, as a body, possess the appropriate skills, independence and experience to oversee the Nuveen Funds’ business. With this overall framework in mind, when the Board, through its Nominating and Governance Committee discussed below, seeks nominees for the Board, the Trustees consider, not only the candidate’s particular background, skills and experience, among other things, but also whether such background, skills and experience enhance the Board’s diversity and at the same time complement the Board given its current composition and the mix of skills and experiences of the incumbent Trustees.

The Board believes the unitary board structure enhances good and effective governance, particularly given the nature of the structure of the investment company complex. Funds in the same complex generally are served by the same service providers and personnel and are governed by the same regulatory scheme which raises common issues that must be addressed by the trustees across the fund complex (such as compliance, valuation, liquidity, brokerage, trade allocation or risk management). The Board believes it is more efficient to have a single board review and oversee common policies and procedures which increases the Board’s knowledge and expertise with respect to the many aspects of fund operations that are complex-wide in nature. The unitary structure also enhances the Board’s influence and oversight over NFALLC, the sub-adviser and other service providers.

In an effort to enhance the independence of the Board, the Board also has a Chairman that is an independent Trustee. The Board recognizes that a chairman can perform an important role in setting the agenda for the Board, establishing the boardroom culture, establishing a point person on behalf of the Board for fund management, and reinforcing the Board’s focus on the long-term interests of shareholders. The Board recognizes that a chairman may be able to better perform these functions without any conflicts of interests arising from a position with fund management. Accordingly, the Trustees have elected Robert P. Bremner as the independent Chairman of the Board through June 30, 2013 and William J. Schneider to serve as the independent chairman of the Board effective July 1, 2013. Specific responsibilities of the Chairman include: (i) presiding at all meetings of the Board and of the shareholders; (ii) seeing that all orders and resolutions of the Trustees are carried into effect; and (iii) maintaining records of and, whenever necessary, certifying all proceedings of the Trustees and the shareholders.

Although the Board has direct responsibility over various matters (such as advisory contracts, underwriting contracts and fund performance), the Board also exercises certain of its oversight responsibilities through several committees that it has established and which report back to the full Board. The Board believes that a committee structure is an effective means to permit the Trustees to focus on particular operations or issues affecting the Nuveen Funds, including risk oversight. More specifically, with respect to risk oversight, the Board has delegated matters relating to valuation and compliance to certain committees (as summarized below) as well as certain aspects of investment risk. In addition, the Board believes that the periodic rotation of Trustees among the different committees allows the Trustees to gain additional and different perspectives of the Fund’s operations. The Board has established seven standing committees: the Executive Committee, the Dividend Committee, the Audit Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Nominating and Governance Committee, the Open-End Funds Committee and the Closed-End Funds Committee. The Board may also from time to time create ad hoc committees to focus on particular issues as the need arises. The membership and functions of the standing committees are summarized below.

The Executive Committee, which meets between regular meetings of the Board, is authorized to exercise all of the powers of the Board. Robert P. Bremner, Chair, Judith M. Stockdale and John P. Amboian serve as the current members of the Executive Committee of the Board. During the fiscal year ended March 31, 2012, the Executive Committee did not meet.

The Dividend Committee is authorized to declare distributions on the Fund’s shares including, but not limited to, regular and special dividends, capital gains and ordinary income distributions. The members of the Dividend Committee are Jack B. Evans, Chair, Judith M. Stockdale and Terence J. Toth. During the fiscal year ended March 31, 2013 the Dividend Committee met four times.

The Compliance, Risk Management and Regulatory Oversight Committee (the “Compliance Committee”) is responsible for the oversight of compliance issues, risk management and other regulatory matters affecting the Nuveen Funds that are not otherwise the jurisdiction of the other committees. The Board has adopted and periodically reviews policies and procedures designed to address the Nuveen Funds’ compliance and risk matters. As part of its duties, the Compliance Committee reviews the policies and procedures relating to compliance matters and recommends modifications thereto as necessary or appropriate to the full Board; develops new policies and procedures as new regulatory matters affecting the Nuveen Funds arise from time to time; evaluates or considers any comments or reports from examinations from regulatory authorities and responses thereto; and performs any special reviews, investigations or other oversight responsibilities relating to risk management, compliance and/or regulatory matters as requested by the Board.

In addition, the Compliance Committee is responsible for risk oversight, including, but not limited to, the oversight of risks related to investments and operations. Such risks include, among other things, exposures to particular issuers, market sectors, or types of securities; risks related to product structure elements, such as leverage; and techniques that may be used to address those risks, such as hedging and swaps. In assessing issues brought to the committee’s attention or in reviewing a particular policy, procedure, investment technique or strategy, the Compliance Committee evaluates the risks to the Nuveen Funds in adopting a particular approach or resolution compared to the anticipated benefits to the Nuveen Funds and their shareholders. In fulfilling its obligations, the Compliance Committee meets on a quarterly basis, and at least once a year in person. The Compliance Committee receives written and oral reports from the Nuveen Funds’ Chief Compliance Officer (“CCO”) and meets privately with the CCO at each of its quarterly meetings. The CCO also provides an annual report to the full Board regarding the operations of the Nuveen Funds’ and other service providers’ compliance programs as well as any recommendations for modifications thereto. The Compliance Committee also receives reports from the investment services group of Nuveen regarding various investment risks. Notwithstanding the foregoing, the full Board also participates in discussions with management regarding certain matters relating to investment risk, such as the use of leverage and hedging. The investment services group therefore also reports to the full Board at its quarterly meetings regarding, among other things, Fund performance and the various drivers of such performance. Accordingly, the Board directly and/or in conjunction with the Compliance Committee oversees matters relating to investment risks. Matters not addressed at the committee level are addressed directly

by the full Board. The committee operates under a written charter adopted and approved by the Board of Trustees. The members of the Compliance Committee are Jack B. Evans, William C. Hunter, William J. Schneider, Virginia L. Stringer and Judith M. Stockdale, Chair. During the fiscal year ended March 31, 2012, the Compliance Committee met five times.

The Audit Committee assists the Board in the oversight and monitoring of the accounting and reporting policies, processes and practices of the Nuveen Funds, and the audits of the financial statements of the Nuveen Funds; the quality and integrity of the financial statements of the Nuveen Funds; the Nuveen Funds’ compliance with legal and regulatory requirements relating to the Nuveen Funds’ financial statements; the independent auditors’ qualifications, performance and independence; and the pricing procedures of the Nuveen Funds and the internal valuation group of Nuveen. It is the responsibility of the Audit Committee to select, evaluate and replace any independent auditors (subject only to Board and, if applicable, shareholder ratification) and to determine their compensation. The Audit Committee is also responsible for, among other things, overseeing the valuation of securities comprising the Nuveen Funds’ portfolios. Subject to the Board’s general supervision of such actions, the Audit Committee addresses any valuation issues, oversees the Nuveen Funds’ pricing procedures and actions taken by Nuveen’s internal valuation group which provides regular reports to the committee, reviews any issues relating to the valuation of the Trustees Funds’ securities brought to its attention and considers the risks to the Funds in assessing the possible resolutions to these matters. The Audit Committee may also consider any financial risk exposures for the Trustees Funds in conjunction with performing its functions.

To fulfill its oversight duties, the Audit Committee receives annual and semi-annual reports and has regular meetings with the external auditors for the Nuveen Funds and the internal audit group at Nuveen Investments. The Audit Committee also may review in a general manner the processes the Board or other Board committees have in place with respect to risk assessment and risk management as well as compliance with legal and regulatory matters relating to the Nuveen Funds’ financial statements. The committee operates under a written charter adopted and approved by the Board. Members of the Audit Committee shall be independent (as set forth in the charter) and free of any relationship that, in the opinion of the Trustees, would interfere with their exercise of independent judgment as an Audit Committee member. The members of the Audit Committee are Robert P. Bremner, David J. Kundert, Chair, William J. Schneider, Carole E. Stone and Terence J. Toth, each of whom is an independent Trustee of the Nuveen Funds. During the fiscal year ended March 31, 2012, the Audit Committee met four times.

The Nominating and Governance Committee is responsible for seeking, identifying and recommending to the Board qualified candidates for election or appointment to the Board. In addition, the Nominating and Governance Committee oversees matters of corporate governance, including the evaluation of Board performance and processes, the assignment and rotation of committee members, and the establishment of corporate governance guidelines and procedures, to the extent necessary or desirable, and matters related thereto. Although the unitary and committee structure has been developed over the years and the Nominating and Governance Committee believes the structure has provided efficient and effective governance, the committee recognizes that as demands on the Board evolve over time (such as through an increase in the number of funds overseen or an increase in the complexity of the issues raised), the committee must continue to evaluate the Board and committee structures and their processes and modify the foregoing as may be necessary or appropriate to continue to provide effective governance. Accordingly, the Nominating and Governance Committee has a separate meeting each year to, among other things, review the Board and committee structures, their performance and functions, and recommend any modifications thereto or alternative structures or processes that would enhance the Board’s governance over the Nuveen Funds’ business.

In addition, the Nominating and Governance Committee, among other things, makes recommendations concerning the continuing education of Trustees; monitors performance of legal counsel and other service providers; establishes and monitors a process by which security holders are able to communicate in writing with members of the Board; and periodically reviews and makes recommendations about any appropriate changes to Trustee compensation. In the event of a vacancy on the Board, the Nominating and Governance Committee

receives suggestions from various sources, including shareholders, as to suitable candidates. Suggestions should be sent in writing to Lorna Ferguson, Manager of Fund Board Relations, Nuveen Investments, 333 West Wacker Drive, Chicago, IL 60606. The Nominating and Governance Committee sets appropriate standards and requirements for nominations for new Trustees and reserves the right to interview any and all candidates and to make the final selection of any new Trustees. In considering a candidate’s qualifications, each candidate must meet certain basic requirements, including relevant skills and experience, time availability (including the time requirements for due diligence site visits to internal and external sub-advisers and service providers) and, if qualifying as an Independent Trustee candidate, independence from the Adviser, sub-advisers, underwriters or other service providers, including any affiliates of these entities. These skill and experience requirements may vary depending on the current composition of the Board, since the goal is to ensure an appropriate range of skills, diversity and experience, in the aggregate. Accordingly, the particular factors considered and weight given to these factors will depend on the composition of the Board and the skills and backgrounds of the incumbent Trustees at the time of consideration of the nominees. All candidates, however, must meet high expectations of personal integrity, independence, governance experience and professional competence. All candidates must be willing to be critical within the Board and with management and yet maintain a collegial and collaborative manner toward other Board members. The committee operates under a written charter adopted and approved by the Board. This committee is composed of the independent Trustees of the Nuveen Funds. Accordingly, the members of the Nominating and Governance Committee are Robert P. Bremner, Chair, Jack B. Evans, William C. Hunter, David J. Kundert, William J. Schneider, Judith M. Stockdale, Carole E. Stone and Terence J. Toth. During the fiscal year ended March 31, 2012, the Nominating and Governance Committee met six times.

Effective January 1, 2012, the Board approved the creation of the Open-End Funds Committee.

Board Diversification and Trustee Qualifications

In determining that a particular Board Member was qualified to serve as a Board Member, the Board has considered each Board Member’s background, skills, experience and other attributes in light of the composition of the Board with no particular factor controlling. The Board believes that Board Members need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties and the Board believes each Board Member satisfies this standard. An effective Board Member may achieve this ability through his or her educational background; business, professional training or practice; public service or academic positions; experience from service as a board member (including the Boards of the Nuveen Funds), or as an executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and or/other life experiences. Accordingly,

COMPENSATION

The following table shows, for each independent trustee, (1) the aggregate compensation paid by the Fund for the fiscal year ended March 31, 2013, (2) the amount of total compensation paid by the Fund that has been deferred and (3) the total compensation paid to each trustee by the Nuveen Funds during the calendar year ended December 31, 2012. The Fund does not have a retirement or pension plan. The officers and trustees affiliated with Nuveen Investments serve without any compensation from the Fund. Certain of the Nuveen Funds have a deferred compensation plan (the “Compensation Plan”) that permits any trustee who is not an “interested person” of certain funds to elect to defer receipt of all or a portion of his or her compensation as a trustee. The deferred compensation of a participating trustee is credited to the book reserve account of a fund when the compensation would otherwise have been paid to the trustee. The value of the trustee’s deferral account at any time is equal to the value that the account would have had if contributions to the account had been invested and reinvested in shares of one or more of the eligible Nuveen Funds. At the time for commencing distributions from a trustee’s

deferral account, the trustee may elect to receive distributions in a lump sum or over a period of five years. The Fund will not be liable for any other fund’s obligations to make distributions under the Compensation Plan.

The Fund’s management fee is separated into two components—a complex-level component, based on the aggregate amount of all fund assets managed by NFALLC, and a specific fund-level component, based only on the amount of assets within the Fund.

Sub-Adviser. Nuveen Asset Management, LLC, 333 West Wacker Drive, Chicago, Illinois 60606, serves as the Fund’s sub-adviser, pursuant to a sub-advisory agreement between NFALLC and Nuveen Asset Management (the “Sub-Advisory Agreement”).

Pursuant to the sub-advisory agreement, Nuveen Asset Management will be compensated for the services it provides to the fund with a portion of the management fee NFALLC receives from the Fund. NFALLC and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

Sub-Advisory Agreement and Related Fees. Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management will receive from NFALLC a management fee equal to 60.000% of NFALLC’s net management fee from the Fund.

PORTFOLIO MANAGER

Unless otherwise indicated, the information below is provided as of the date of this SAI.

Portfolio Management. Thomas Spalding, CFA (the “Portfolio Manager”), is Vice President and Senior Investment Officer of Nuveen Investments and has been the portfolio manager of the Fund since 1999. He has direct investment responsibility for National Long Term funds. He joined Nuveen in 1976 as assistant portfolio manager and has been the portfolio manager of the Nuveen Municipal Value Fund, Nuveen’s first closed-end exchange traded fund, since its inception in 1987. Currently, he manages investments for 21 Nuveen-sponsored investment companies.

The Portfolio Manager also has responsibility for the day-to-day management of accounts other than the Fund. Information regarding these other accounts is set forth below.


	Number of Other Accounts Managed and Assets by Account Type as of March 31, 2012
Portfolio Manager	Type of Account Managed	Number of Accounts		Total Assets		Number of Accounts with Performance Based Fees		Assets of Account with Performance Based Fees
Thomas Spalding	Registered Investment Companies		20		$8.58 billion		0		$0
	Other Pooled Investment Vehicles		0		$0		0		$0
	Other Accounts		5		$18.9 million		0		$0

The Portfolio Manager is responsible for managing the Fund and other accounts, including separate accounts and unregistered funds.

As shown in the above table, the Portfolio Manager may manage accounts in addition to the Fund. The potential for conflicts of interest exists when a portfolio manager manages other accounts with similar investment objectives and strategies to the Fund (“Similar Accounts”). Potential conflicts may include, for example, conflicts between investment strategies and conflicts in the allocation of investment opportunities.

Responsibility for managing NFALLC’s clients’ portfolios is organized according to investment strategies. Generally, client portfolios with similar strategies are managed using the same objectives, approach and philosophy. Therefore, portfolio holdings, relative position sizes and sector exposures tend to be similar across similar portfolios which minimizes the potential for conflicts of interest.

NFALLC may receive more compensation with respect to certain Similar Accounts than that received with respect to the Fund or may receive compensation based in part on the performance of certain Similar Accounts. This may create a potential conflict of interest for the Portfolio Manager by providing an incentive to favor these Similar Accounts when, for example, placing securities transactions. Potential conflicts of interest may arise with both the aggregation and allocation of securities transactions and allocation of limited investment opportunities. Allocations of aggregated trades, particularly trade orders that were only partially completed due to limited availability, and allocation of investment opportunities generally, could raise a potential conflict of interest.

Nuveen Asset Management has policies and procedures designed to manage these conflicts described above such as allocation of investment opportunities to achieve fair and equitable allocation of investment opportunities among its clients over time. For example, orders for the same equity security are aggregated on a continual basis throughout each trading day consistent with Nuveen Asset Management’s duty of best execution for its clients. If aggregated trades are fully executed, accounts participating in the trade will be allocated their pro rata share on an average price basis. Partially completed orders will be allocated among the participating accounts on a pro-rata average price basis as well.

Compensation. The Portfolio Manager’s compensation consists primarily of base pay, an annual cash bonus and long-term incentive payments.

Base pay. Base pay is determined based upon an analysis of the Portfolio Manager’s general performance, experience, and market levels of base pay for such position.

Annual cash bonus. The Portfolio Manager is eligible for an annual cash bonus based on investment performance, qualitative evaluation and financial performance of Nuveen Asset Management.

A portion of the Portfolio Manager’s annual cash bonus is based on the Fund’s investment performance, generally measured over the past one- and three or five-year periods unless the portfolio manager’s tenure is shorter. Investment performance for the Fund generally is determined by evaluating the Fund’s performance relative to its benchmark(s) and/or Lipper industry peer group.

A portion of the cash bonus is based on a qualitative evaluation made by the Portfolio Manager’s supervisor taking into consideration a number of factors, including the portfolio manager’s team collaboration, expense management, support of personnel responsible for asset growth, and his or her compliance with Nuveen Asset Management’s policies and procedures.

The final factor influencing the Portfolio Manager’s cash bonus is the financial performance of Nuveen Asset Management based on its operating earnings.

Long-term incentive compensation. Certain key employees of Nuveen Investments and its affiliates, including certain portfolio managers, have received equity interests in the parent company of Nuveen Investments. In addition, certain key employees of Nuveen Asset Management, including certain portfolio managers, have received profits interests in Nuveen Asset Management which entitle their holders to participate in the firm’s growth over time.

Material Conflicts of Interest. Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for the Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by the portfolio manager. Finally,

the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Fund Shares Owned by the Portfolio Manager. As of December 31, 2011, the Portfolio Manager beneficially owned (as determined pursuant to Rule 16a-1(a)(2) under the 1934 Act) shares of the Fund having values within the indicated dollar range.

CODES OF ETHICS

The Fund, NFALLC, Nuveen Asset Management, Nuveen Securities and other related entities have adopted codes of ethics that essentially prohibit certain of their personnel, including the Portfolio Manager, from engaging in personal investments that compete or interfere with, or attempt to take advantage of a client’s, including the Fund’s, anticipated or actual portfolio transactions, and are designed to assure that the interests of clients, including Fund shareholders, are placed before the interests of personnel in connection with personal investment transactions. Personnel subject to the codes of ethics may purchase shares of the Fund subject to the restriction set forth in such codes. While personnel subject to the codes of ethics may generally invest in securities in which the Fund may also invest, portfolio managers of municipal bond funds, such as the Fund may not do so. Text-only versions of the codes of ethics of the Fund, NFALLC, Nuveen Asset Management, and Nuveen can be viewed online or downloaded from the EDGAR Database on the SEC’s internet web site at www.sec.gov. You may also review and copy those documents by visiting the SEC’s Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 202-551-8090. In addition, copies of those codes of ethics may be obtained, after mailing the appropriate duplicating fee, by writing to the SEC’s Public Reference Section, 100 F Street, N.E., Washington, DC 20549-0102 or by e-mail request at publicinfo@sec.gov.

PROXY VOTING POLICIES

The Fund invests primarily in municipal securities. On rare occasions the Fund may acquire, directly or through a special purpose vehicle, equity securities of a municipal bond issuer whose bonds the Fund already owns when such bonds have deteriorated or are expected shortly to deteriorate significantly in credit quality. The purpose of acquiring equity securities generally will be to acquire control of the municipal bond issuer and to seek to prevent the credit deterioration or facilitate the liquidation or other workout of the distressed issuer’s credit problem. In the course of exercising control of a distressed municipal issuer, Nuveen Asset Management may pursue the Fund’s interests in a variety of ways, which may entail negotiating and executing consents, agreements and other arrangements, and otherwise influencing the management of the issuer. Nuveen Asset Management does not consider such activities proxy voting for purposes of Rule 206(4)-6 under the Investment Advisers Act of 1940, as amended, but nevertheless provides reports to the Fund’s Board of Trustees on its control activities on a quarterly basis.

In the rare event that a municipal issuer held by the Fund were to issue a proxy, or that the Fund were to receive a proxy issued by a cash management security, Nuveen Asset Management would either engage an

independent third party to determine how the proxy should be voted or vote the proxy with the consent, or based on the instructions, of the Fund’s Board of Trustees or its representative. In the case of a conflict of interest, the proxy would be submitted to the Fund’s Board to determine how the proxy should be voted. A member of Nuveen Asset Management’s legal department would oversee the administration of the voting, and ensure that records were maintained in accordance with Rule 206(4)-6, reports were filed with the SEC on Form N-PX, and the results provided to the Fund’s Board of Trustees and made available to shareholders as required by applicable rules. When required by applicable regulations, information regarding how the Fund voted proxies relating to portfolio securities during the most recent twelve-month period ended March 31 is available without charge, upon request, by calling (800) 257-8787 or from the Fund’s website at http://www.nuveen.com, and on the Securities and Exchange Commission’s website at http://www.sec.gov.

PORTFOLIO TRANSACTIONS AND BROKERAGE

Subject to the supervision of the Board of Trustees, Nuveen Asset Management is responsible for decisions to purchase and sell securities for the Fund, the negotiation of the prices to be paid and the allocation of transactions among various dealer firms. Transactions on stock exchanges involve the payment by the Fund of brokerage commissions. There generally is no stated commission in the case of securities traded in the over-the-counter (“OTC”) market but the price paid by the Fund usually includes an undisclosed dealer commission or mark-up. Transactions in the OTC market can also be placed with broker-dealers who act as agents and charge brokerage commissions for effecting OTC transactions. The Fund may place its OTC transactions either directly with principal market makers, or with broker-dealers if that is consistent with Nuveen Asset Management’s obligation to obtain best qualitative execution. In certain instances, the Fund may make purchases of underwritten issues at prices that include underwriting fees.

Portfolio securities may be purchased directly from an underwriter or in the OTC market from the principal dealers in such securities, unless it appears that a better price or execution may be obtained through other means. Portfolio securities will not be purchased from Nuveen Investments or its affiliates or affiliates of NFALLC except in compliance with the 1940 Act.

It is Nuveen Asset Management’s policy to seek the best execution under the circumstances of each trade. Nuveen Asset Management will evaluate price as the primary consideration, with the financial condition, reputation and responsiveness of the dealer considered secondary in determining best execution. Given the best execution obtainable, it will be Nuveen Asset Management’s practice to select dealers that, in addition, furnish research information (primarily credit analyses of issuers and general economic reports) and statistical and other services to Nuveen Asset Management. It is not possible to place a dollar value on information and statistical and other services received from dealers. Since it is only supplementary to Nuveen Asset Management’s own research efforts, the receipt of research information is not expected to reduce significantly Nuveen Asset Management’s expenses. While Nuveen Asset Management will be primarily responsible for the placement of the business of the Fund, Nuveen Asset Management’s policies and practices in this regard must be consistent with the foregoing and will, at all times, be subject to review by the Board of Trustees of the Fund.

Nuveen Asset Management may manage other investment accounts and investment companies for other clients that may invest in the same types of securities as the Fund and that may have investment objective similar to those of the Fund. Nuveen Asset Management seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell assets or securities by the Fund and another advisory account. If an aggregated order cannot be filled completely, allocations will generally be made on a pro rata basis. An order may not be allocated on a pro rata basis where, for example (i) consideration is given to portfolio managers who have been instrumental in developing or negotiating a particular investment; (ii) consideration is given to an account with specialized investment policies that coincide with the particulars of a specific investment; (iii) pro rata allocation would result in odd-lot or de minimis amounts being allocated to a portfolio or other client; or (iv) where Nuveen Asset Management reasonably determines that departure from a pro rata allocation is

advisable. There may also be instances where the Fund will not participate at all in a transaction that is allocated among other accounts. While these allocation procedures could have a detrimental effect on the price or amount of the securities available to the Fund from time to time, it is the opinion of the Board of Trustees that the benefits available from Nuveen Asset Management’s management outweigh any disadvantage that may arise from Nuveen Asset Management’s larger management activities and its need to allocate securities.

During the fiscal year ended March 31, 2012, the Fund did not pay commissions to brokers in return for research services or hold any securities of its regular broker dealers.

NET ASSET VALUE

The Fund’s net asset value per share is determined as of the close of regular session trading (normally 4:00 p.m., Eastern Time) on each day the NYSE is open for business. Net asset value is calculated by taking the fair value of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share. All valuations are subject to review by the Fund’s Board of Trustees or its delegate, Nuveen Asset Management.

In determining net asset value, expenses are accrued and applied daily, and securities and other assets for which market quotations are available are valued daily at market value. The prices of fixed income securities are provided by a pricing service and are based on the mean between the bid and asked price. When price quotes are not readily available, which is typically the case for municipal bonds, the pricing service establishes a security’s fair value based on various factors, including prices of comparable fixed income securities utilizing a matrix pricing system. Due to the subjective and variable nature of fair value pricing, it is possible that the fair value determined for a particular security may be different from the value realized upon the sale of the security.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board of Trustees or its delegate at fair value. These securities generally include but are not limited to, restricted securities (securities that may not be publicly sold without registration under the Securities Act of 1933) 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 net asset value; a security with respect to which an event has occurred that is likely to make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s “fair value.” As a general principle, the current “fair value” of a security would be the amount that the owner might reasonably expect to receive for it upon its current sale. A variety of factors may be considered in determining the fair value of such securities.

DISTRIBUTIONS

The Fund pays regular monthly distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per Common Share dividend rate) that reflects the past and projected performance of the Fund. Distributions can only be made from net investment income after paying any interest and required principal payments on borrowings to preferred shareholders, if preferred shares are issued in the future.

To permit the Fund to maintain a more stable monthly distribution, the Fund may from time to time distribute less than the entire amount of net investment income earned in a particular period. Such undistributed net investment income would be available to supplement future distributions, including distributions that might otherwise have been reduced by a decrease in the Fund’s monthly net income due to fluctuations in investment income or expenses, an increase in interest payments on borrowings or due to an increase in the dividend rate on

the Fund’s outstanding preferred shares, if issued in the future. As a result, the distributions paid by the Fund for any particular period may be more or less than the amount of net investment income actually earned by the Fund during such period. However, the Fund intends to maintain distributions of net investment income for any period in amounts sufficient to continue to qualify for treatment under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), as a regulated investment company (as explained more fully below in “Tax Matters”). Undistributed net investment income will be added to the Fund’s net asset value and, correspondingly, distributions from undistributed net investment income will be deducted from the Fund’s net asset value.

As explained more fully below in “Tax Matters,” at least annually, the Fund intends to distribute to Common Shareholders any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) after paying any interest and required principal payments on borrowings and making any redemption or liquidation payments to preferred shareholders, if preferred shares are issued in the future or, alternatively, to retain all or a portion of the year’s net capital gain. The Fund will pay federal income tax on any net capital gain not used to pay distributions to shareholders. Each Common Shareholder of record as of the end of the Fund’s taxable year will include in income for federal income tax purposes, as long-term capital gain, his or her share of the retained gain will be deemed to have paid his or her proportionate share of tax paid by the Fund, and will be entitled to an income tax credit or refund for that share of the tax.

For tax purposes, the Fund is currently required to allocate net capital gain and other taxable income, if any, between Common Shares and preferred shares, if preferred shares are issued in the future, in proportion to total dividends paid to each class for the year in which such net capital gain or other taxable income is realized. For information relating to the impact of the issuance of preferred shares on the distributions made by the Fund to Common Shareholders, see the Prospectus under “Use of Leverage.”

If preferred shares are outstanding, the Fund may not declare any cash dividend or other distribution on its Common Shares unless at the time of such declaration (1) all accumulated dividends on the preferred shares have been paid, (2) all interest and required principal on borrowings has been paid, (3) the net asset value of the Fund’s portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of the liquidation value of any outstanding preferred shares and (4) the net asset value of the Fund’s portfolio (determined after deducting the amount of such dividend or other distribution) is at least 300% of the value of the Fund’s borrowings. These limitations on the Fund’s ability to make distributions on its Common Shares could under certain circumstances impair the ability of the Fund to maintain its qualification for treatment as a regulated investment company.

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time.

DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (the “Plan”), you may elect to have all dividends, including any capital gain dividends, on your Common Shares automatically reinvested by the Plan Agent (defined below) in additional Common Shares under the Plan. You may elect to participate in the Plan by contacting Nuveen Investor Services at (800) 257-8787. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you or your brokerage firm by State Street Bank and Trust Company as dividend paying agent (the “Plan Agent”).

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

(1) If Common Shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the then current market price;

(2) If Common Shares are trading below net asset value at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the Exchange or elsewhere, for the participants” accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments; or

For shares of the Fund held in the Plan, you are permitted to elect from among several permitted cost basis methods. In the absence of an election, the Plan will use first-in first-out (“FIFO”) methodology for tracking and reporting your cost basis on covered shares as its default cost basis method. The cost basis method you use may not be changed with respect to a repurchase of shares after the settlement date of the repurchase. You should consult with your tax advisors to determine the best permitted cost basis method for your tax situation and to obtain more information about how the new cost basis reporting rules apply to you. The Plan Agent maintains all stockholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Upon a sale of your stock, the Fund (or its administrative agent) may be required to report to the IRS and furnish to you cost basis and holding period information for the Fund’s stock purchased on or after January 1, 2012 (“covered shares”).

For stock of the Fund held in the Plan, you are permitted to elect from among several permitted cost basis methods. In the absence of an election, the Plan will use first-in first-out (“FIFO”) methodology for tracking and reporting your cost basis on covered shares as its default cost basis method. The cost basis method you use may not be changed with respect to a repurchase by the Fund of stock after the settlement date of the repurchase. You should consult with your tax advisors to determine the best permitted cost basis method for your tax situation and to obtain more information about how the new cost basis reporting rules apply to you.

Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained from State Street Bank and Trust Company, Attn: ComputerShare Nuveen Investments, P.O. Box 43071, Providence, Rhode Island 02940-3071, (800) 257-8787.

Distribution Through At-the-Market Transactions

The Fund has entered into a Distribution Agreement with Nuveen Securities, a form of which has been filed as an exhibit to the Registration Statement of which this Prospectus is a part. The summary of the Distribution Agreement contained herein is qualified by reference to the Distribution Agreement. Subject to the terms and conditions of the Distribution Agreement, the Fund may issue and sell Common Shares from time to time through Nuveen Securities to certain broker-dealers that have entered into selected dealer agreements with Nuveen Securities.

The summary of the Selected Dealer Agreement contained herein is qualified by reference to the Selected Dealer Agreement.

Common Shares will only be sold on such days as shall be agreed to by the Fund and Nuveen Securities. Common Shares will be sold at market prices, which shall be determined with reference to trades on the NYSE, subject to a minimum price to be established each day by the Fund. The minimum price on any day will not be less than the current NAV per Common Share plus the per share amount of the commission to be paid to Nuveen Securities.

Distribution Through Underwriting Syndicates

The Fund from time to time may issue additional Common Shares through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s Common Shares, underwriters will market and price the offering on an expedited basis, e.g., in an overnight or similarly abbreviated offering period. The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities, one of the Fund’s underwriters, and the underwriting syndicate.

The Fund will offer its shares at a price equal to a specified discount of up to 2% from the closing market price of the Fund’s Common Shares on the day prior to the offering date. The applicable discount will be negotiated by the Fund and Nuveen Securities in consultation with the underwriting syndicate on a transaction-by-transaction basis. The Fund will compensate the underwriting syndicate out of the proceeds of the offering based upon a sales load of up to 4% of the gross proceeds of the sale of Common Shares.

The applicable discount will be determined by the Fund on a transaction-by-transaction basis.

The principal business address of Nuveen Securities is 333 West Wacker Drive, Chicago, Illinois 60606.

DESCRIPTION OF SHARES

COMMON SHARES

The Declaration of Trust (the “Declaration”) authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to the rights of holders of preferred shares, if issued, and borrowings, if incurred, have equal rights to the payment of dividends and the distribution of assets upon liquidation. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed in “Certain Provisions in the Declaration of Trust,” non-assessable, and will have no pre-emptive or conversion rights or rights to cumulative voting. Each Common Share has one vote with respect to matters upon which a shareholder vote is required, consistent with the requirements of the 1940 Act and the rules promulgated thereunder, and will vote together as a single class. Whenever the Fund incurs borrowings and/or preferred shares are outstanding, Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all interest on such borrowings has been paid and all accrued dividends on preferred shares have been paid, unless asset coverage (as defined in the 1940 Act) with respect to any borrowings would be at least 300% after giving effect to the distributions and asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to the distributions. See “—Preferred Shares,” below.

The Common Shares are listed on the NYSE and trade under the ticker symbol “NXP.” The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will not issue share certificates.

BORROWINGS

portfolio coverages or otherwise. In addition, as with the issuance of preferred shares, certain types of borrowings may result in the Fund being subject to certain restrictions imposed by guidelines of one or more rating agencies that may issue ratings for commercial paper or notes issued by the Fund. Such restrictions may be more stringent than those imposed by the 1940 Act.

The rights of lenders to the Fund to receive interest on and repayment of principal of any such borrowings will be senior to those of the Common Shareholders, and the terms of any such borrowings may contain provisions which limit certain activities of the Fund, including the payment of dividends to Common Shareholders in certain circumstances. Further, the 1940 Act does (in certain circumstances) grant to the lenders to the Fund certain voting rights in the event of default in the payment of interest on or repayment of principal. In the event that such provisions would impair the Fund’s eligibility for treatment as a regulated investment company under the Code, the Fund will attempt to repay or restructure the borrowings to preserve that eligibility. Any borrowings will likely be ranked senior or equal to all other existing and future borrowings of the Fund. The Fund may also borrow up to an additional 5% of its total assets for temporary purposes. The Fund may also borrow money for repurchase of its shares or as a temporary measure for extraordinary or emergency situations.

PREFERRED SHARES

The Declaration authorizes the issuance of an unlimited number of preferred shares in one or more classes or series, with rights as determined by the Board of Trustees, by action of the Board of Trustees without the approval of the Common Shareholders. The Fund does not currently have any preferred shares outstanding. The Fund may issue preferred shares in the future to increase the Fund’s leverage. The decision to issue additional preferred shares is subject to market conditions and to the Board of Trustee’s belief that leveraging the Fund’s capital structure through the issuance of preferred shares is likely to achieve the benefits to the Common Shareholders described in the Prospectus.

Distribution Preference. If issued in the future, the preferred shares would have complete priority over the Common Shares as to distribution of assets.

Voting Rights. Preferred shares are required to be voting shares and to have equal voting rights with Common Shares. Except as otherwise indicated in this SAI and except as otherwise required by applicable law, holders of preferred shares, if issued in the future, would vote together with Common Shareholders as a single class.

the holders of all outstanding preferred shares, if issued in the future, voting as a separate class, would be entitled to elect a majority of the Fund’s trustees until all dividends in arrears have been paid or declared and set apart for payment. In order for the Fund to take certain actions or enter into certain transactions, a separate class vote of holders of preferred shares, if issued in the future, would be required, in addition to the single class vote of the holders of preferred shares, if issued in the future, and Common Shares. See “Certain Provisions in the Declaration of Trust.”

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST

The Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. Specifically, the Declaration requires a vote by holders of at least two-thirds of the Common Shares and preferred shares, if issued in the future, voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund’s assets (other than in the regular course of the Fund’s investment activities), (4) in certain circumstances, a termination of the Fund, or a series or class of the Fund, or (5) a removal of trustees by shareholders (except at the end of a trustee’s term), and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, in which case the affirmative vote of the holders of at least a majority of the Fund’s Common Shares and preferred shares, if issued in the future, outstanding at the time, voting together as a single class, is required; provided, however, that where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), only the required vote by the applicable class or series will be required. Approval of shareholders is not required, however, for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization which adversely affects the holders of preferred shares, if issued in the future, the action in question will also require the affirmative vote of the holders of at least two-thirds of the Fund’s preferred shares, if issued in the future, outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, the affirmative vote of the holders of at least a majority of the Fund’s preferred shares, if issued in the future, outstanding at the time, voting as a separate class. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the Common Shares and preferred shares, if issued in the future, voting together as a single class. The votes required to approve the

conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of preferred shares, if issued in the future, are higher than those required by the 1940 Act. The Board of Trustees believes that the provisions of the Declaration relating to such higher votes are in the best interest of the Fund and its shareholders.

The provisions of the Declaration described above could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund’s investment objective and policies. The Board of Trustees is divided into three classes, such a staggered board could delay for up to two years the replacement of a majority of the Board of Trustees. The Board of Trustees of the Fund has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund and its Common Shareholders.

Reference should be made to the Declaration on file with the SEC for the full text of these provisions.

The Declaration provides that the obligations of the Fund are not binding upon the trustees of the Fund individually, but only upon the assets and property of the Fund, and that the trustees shall not be liable for errors of judgment or mistakes of fact or law. Nothing in the Declaration, however, protects a trustee against any liability to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Fund is a closed-end investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Fund’s common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection, price, dividend stability, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than net asset value, the Fund’s Board of Trustees has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Fund to an open-end investment company. There can be no assurance, however, that the Board of Trustees will decide to take any of these actions, or that share repurchases or tender offers, if undertaken, will reduce market discount. On November 16, 2011, the Fund’s Board of Trustees approved an open market share repurchase program under which the Fund may repurchase up to 10% of its Common Shares. To date, the Fund has not repurchased any Common Shares under the program.

Notwithstanding the foregoing, at any time if the Fund has preferred shares outstanding, the Fund may not purchase, redeem or otherwise acquire any of its Common Shares unless (1) all accrued preferred shares dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the net asset value of the Fund’s portfolio (determined after deducting the acquisition price of the Common Shares) is at least 200% of the liquidation value of the outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). The staff of the SEC currently requires that any tender offer made by a closed-end investment company for its shares must be at a price equal to the net asset value of such shares at the close of business on the last day of the tender offer. Any service fees incurred in connection with any tender offer made by the Fund will be borne by the Fund and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment limitations, the Fund may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the Fund in anticipation of share repurchases or tenders will reduce the Fund’s net income. Any share repurchase, tender offer or borrowing that might be approved by the Board of Trustees would have to comply with the Securities Exchange Act of 1934, as amended, and the 1940 Act and the rules and regulations thereunder.

Although the decision to take action in response to a discount from net asset value will be made by the Board of the Fund at the time it considers such issue, it is the Board’s present policy, which may be changed by the Board, not to authorize repurchases of common shares or a tender offer for such shares if (1) such transactions, if consummated, would (a) result in the delisting of the common shares from the NYSE, or (b) impair the Fund’s eligibility for treatment as a regulated investment company under the Code or impair the Fund’s status as a registered closed-end investment company under the 1940 Act; (2) the Fund would not be able to liquidate portfolio securities in an orderly manner and consistent with the Fund’s investment objective and policies in order to repurchase shares; or (3) there is, in the Board’s judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Fund, (b) general suspension of or limitation on prices for trading securities on the NYSE, (c) declaration of a banking moratorium by Federal or state authorities or any suspension of payment by United States or state banks in which the Fund invests, (d) material limitation affecting the Fund or the issuers of its portfolio securities by federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the Fund or its shareholders if shares were repurchased. The Board of Trustees of the Fund may in the future modify these conditions in light of experience.

Conversion to an open-end company would require the approval of the holders of at least two-thirds of the Fund’s common shares and preferred shares, if issued in the future, outstanding at the time, voting together as a single class, and of the holders of at least two-thirds of the Fund’s preferred shares, if issued in the future, outstanding at the time, voting as a separate class, provided however, that such separate class vote shall be a majority vote if the action in question has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or By-Laws. See the Prospectus under “Certain Provisions in the Declaration of Trust” for a discussion of voting requirements applicable to conversion of the Fund to an open-end company. If the Fund converted to an open-end company, it would be required to redeem all preferred shares then outstanding, and the Fund’s common shares would no longer be listed on the NYSE. Shareholders of an open-end investment company may require the company to redeem their shares on any business day (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less such redemption charge, if any, as might be in effect at the time of redemption. In order to avoid maintaining large cash positions or liquidating favorable investments to meet redemptions, open-end companies typically engage in a continuous offering of their shares. Open-end companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management. The Board of Trustees of the Fund may at any time propose conversion of the Fund to an open-end company depending upon their judgment as to the advisability of such action in light of circumstances then prevailing.

The repurchase by the Fund of its shares at prices below net asset value would result in an increase in the net asset value of those shares that remain outstanding. However, there can be no assurance that share repurchases or tenders at or below net asset value would result in the Fund’s shares trading at a price equal to their net asset value. Nevertheless, the fact that the Fund’s shares may be the subject of repurchase or tender offers at net asset value from time to time, or that the Fund may be converted to an open-end company, may reduce any spread between market price and net asset value that might otherwise exist.

In addition, a purchase by the Fund of its common shares would decrease the Fund’s total assets which would likely have the effect of increasing the Fund’s expense ratio. Any purchase by the Fund of its common shares at a time when preferred shares are outstanding will increase the leverage applicable to the outstanding common shares then remaining.

Before deciding whether to take any action if the Fund’s common shares trade below net asset value, the Board of the Fund would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund’s portfolio, the impact of any action that might be taken on the Fund or its shareholders and market considerations. Based on these considerations, even if the Fund’s shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken.

TAX MATTERS

The following is intended to be a general summary of certain US federal income tax consequences of investing, holding and disposing of common shares of the Fund. It is not intended to be a complete discussion of all such federal income tax consequences, nor does it purport to deal with all categories of investors (including investors in common shares with large positions in the Fund). Investors are advised to consult with their own tax advisors before investing in the Fund.

The Fund has elected and intends to qualify each year to be treated, as a regulated investment company (a “RIC”) under Subchapter M of the Code. The Fund also intends to satisfy conditions under which dividends on common shares attributable to interest on municipal securities (as defined above) are exempt from federal income tax in the hands of owners of such stock, subject to the possible application of the federal alternative minimum tax.

To qualify under Subchapter M of the Code for treatment as a RIC, the Fund must, among other things: (a) distribute to its shareholders each year at least 90% of the sum of (i) its investment company taxable income (as that term is defined in the Code, determined without regard to the deduction for dividends paid) and (ii) its net tax-exempt income (the excess of its gross tax-exempt interest income over certain disallowed deductions), (b) derive at least 90% of its gross income (including income on municipal securities exempt from regular federal income tax) for each taxable year from dividends, interest (including interest income on municipal securities exempt from regular federal income tax), payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from an interest in a qualified publicly traded partnership (as defined in the Code), and (c) diversify its holdings so that, at the end of each quarter of the Fund’s taxable year (i) at least 50% of the market value of the Fund’s assets is represented by cash, cash items, U.S. government securities, securities of other regulated investment companies, and other securities, with these other securities limited, with respect to any one issuer, to an amount not greater in value than 5% of the Fund’s total assets, and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the market value of the Fund’s assets is invested in the securities of any one issuer (other than U.S. government securities or securities of other regulated investment companies), the securities of two or more issuers (other than securities of other regulated investment companies) controlled by the Fund and engaged in the same, similar or related trades or businesses, or the securities of one or more qualified publicly traded partnerships. To meet these requirements, the Fund may need to restrict its use of certain of the investment techniques described under “Investment Policies and Techniques” and “Other Investment Policies and Techniques” above.

If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period of time. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions are not available to the Fund and it fails to qualify for treatment as a RIC for a taxable year, the Fund will be taxable at regular corporate tax rates (and, to the extent applicable, at corporate alternative minimum tax rates). In such an event, all distributions (including capital gains distributions and distributions derived from interest on municipal securities) will be taxable as ordinary dividends to the extent of the Fund’s current and accumulated

earnings and profits, subject to the dividends-received deduction for corporate shareholders and to the lower tax rates applicable to qualified dividend income distributed to individuals. Distributions in excess of the Fund’s current and accumulated earnings and profits would be treated first as a tax-free return of capital to the extent of the holder’s adjusted tax basis in the shares (reducing that basis accordingly), and any remaining distributions would generally be treated as a capital gain. To requalify for treatment as a RIC in a subsequent taxable year, the Fund would be required to satisfy the RIC qualification requirements for that year and to distribute any earnings and profits from any year in which the Fund failed to qualify for tax treatment as a RIC. In addition, if the Fund failed to qualify as a RIC for a period greater than two taxable years, it would generally be required to pay a Fund-level tax on certain net built-in gains recognized with respect to certain of its assets upon a disposition of such assets within ten years of qualifying as a RIC in a subsequent year.

A regulated investment company that fails to distribute, by the close of each calendar year, an amount at least equal to the sum of 98% of its ordinary taxable income for such year and 98.2% of its capital gain net income for the one-year period ending October 31 in such year, plus any shortfalls from the prior year’s required distribution, is liable for a nondeductible 4% federal excise tax on the excess of the required distribution for such calendar year over the distributed amount for such calendar year. To avoid the imposition of this excise tax, the Fund generally intends to make the required distributions of its ordinary taxable income, if any, and its capital gain net income, to the extent possible, by the close of each calendar year.

Certain minimum net asset value coverage limitations on distributions made with respect to Common Stock may under certain circumstances impair the ability of the Fund to maintain its qualification for treatment as a RIC or to pay distributions sufficient to avoid the imposition of the 4% federal excise tax.

As described in “Distributions” above, the Fund may retain for investment or otherwise use some (or all) of its net capital gain. If the Fund retains any net capital gain or taxable net investment income, it will be subject to tax at regular corporate rates on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their shares of such undistributed amount; (ii) will be deemed to have paid their proportionate shares of the tax paid by the Fund on such undistributed amount and will be entitled to credit that amount of tax against their federal income tax liabilities, if any; and (iii) will be entitled to claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of the Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder.

The Fund intends to qualify to pay “exempt-interest” dividends, as defined in the Code, to its common shares by satisfying the requirement that, at the close of each quarter of its taxable year, at least 50% of the value of its total assets consists of municipal securities. Exempt-interest dividends are dividends or any part thereof (other than a capital gain dividend) paid by the Fund which are attributable to interest on municipal securities and which are so reported by the Fund. Exempt-interest dividends will be exempt from federal income tax, subject to the possible application of the federal alternative minimum tax. Insurance proceeds received by the Fund under any insurance policies in respect of scheduled interest payments on defaulted municipal bonds, as described herein, will generally be correspondingly excludable from federal gross income. In the case of non-appropriation by a political subdivision, however, there can be no assurance that payments made by the issuer representing interest on municipal lease obligations will be excludable from gross income for federal income tax purposes. See “Investment Policies and Techniques” above. Any gains of the Fund that are attributable to market discount on municipal securities are treated as ordinary income to the extent of accrued market discount on those securities.

A 3.8% Medicare contribution tax generally applies to all or a portion of the net investment income of a shareholder who is an individual and not a nonresident alien for federal income tax purposes and who has adjusted gross income (subject to certain adjustments) that exceeds a threshold amount ($250,000 if married

filing jointly or if considered a “surviving spouse” for federal income tax purposes, $125,000 if married filing separately, and $200,000 in other cases). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts. For these purposes, interest, dividends and certain capital gains are generally taken into account in computing a shareholder’s net investment income, but exempt-interest dividends are not taken into account.

A portion of the Fund’s expenditures that would otherwise be deductible may not be allowed as deductions by reason of the Fund’s investment in municipal securities (such disallowed portion, in general, being the same percentage of the Fund’s aggregate expenses as the percentage of the Fund’s aggregate gross income that constitutes exempt interest income from municipal securities). A similar disallowance rule also applies to interest expense paid or incurred by the Fund, if any. Any such disallowed deductions will offset the Fund’s gross exempt-interest income for purposes of calculating the dividends that the Fund can report as exempt-interest dividends. Interest on indebtedness incurred or continued to purchase or carry the Fund’s shares is not deductible to the extent the interest relates to exempt-interest dividends. Under rules used by the IRS for determining when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of such shares.

Distributions to shareholders of net investment income received by the Fund from taxable investments, if any, including temporary taxable investments, and of net short-term capital gains realized by the Fund, if any, will be taxable to its shareholders as ordinary income. Distributions by the Fund of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss), if any, are taxable as long-term capital gain, regardless of the length of time the shareholder has owned the shares with respect to which such distributions are made. The amount of taxable income allocable to the Fund’s shares will depend upon the amount of such income realized by the Fund. Distributions, if any, in excess of the Fund’s earnings and profits will first reduce the adjusted tax basis of a shareholder’s shares and, after that basis has been reduced to zero, will constitute capital gain to the shareholder (assuming the shares are held as capital assets). As long as the Fund qualifies as a RIC under the Code, it is not expected that any part of its distributions to shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders or as “qualified dividend income” taxable to noncorporate shareholders at reduced rates.

The IRS requires the Fund to report distributions paid with respect to its Common Shares and any preferred shares, if any such preferred shares are issued in the future, as consisting of a portion of each type of income distributed by the Fund. The portion of each type of income deemed received by the holders of each class of shares will be equal to the portion of total Fund dividends received by such class. Thus, the Fund will report dividends paid as exempt-interest dividends in a manner that allocates such dividends between the holders of the common shares and any preferred shares, if any such shares are issued in the future, in proportion to the total dividends paid to each such class during or with respect to the taxable year, or otherwise as required by applicable law. Capital gain dividends and ordinary income dividends will also be allocated between the two classes under these rules.

The interest on private activity bonds in most instances is not federally tax-exempt to a person who is a “substantial user” of a facility financed by such bonds or a “related person” of such “substantial user.” As a result, the Fund may not be an appropriate investment for a shareholder who is considered either a “substantial user” or a “related person” within the meaning of the Code. In general, a “substantial user” of a facility includes a “nonexempt person who regularly uses a part of such facility in his trade or business.” “Related persons” are in general defined to include persons among whom there exists a relationship, either by family or business, which would result in a disallowance of losses in transactions among them under various provisions of the Code (or if they are members of the same controlled group of corporations under the Code), including a partnership and each of its partners (and certain members of their families), an S corporation and each of its shareholders (and certain members of their families) and various combinations of these and other relationships. The foregoing is not a complete description of all of the provisions of the Code covering the definitions of “substantial user” and “related person.”

Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months and paid during the following January, will be treated as having been distributed by the Fund (and received by the shareholders) on December 31 of the year declared. The U.S. federal income tax status of all distributions will be reported to shareholders annually.

Federal income tax law imposes an alternative minimum tax with respect to corporations, individuals, trusts and estates. Interest on certain municipal securities, such as bonds issued to make loans for housing purposes or to private entities (but not to certain tax-exempt organizations such as universities and non-profit hospitals), is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. If the Fund receives income from municipal securities the interest on which is a tax preference item, a portion of the dividends paid by the Fund, although otherwise exempt from federal income tax, will be taxable to shareholders whose tax liabilities are determined under the federal alternative minimum tax. The Fund will annually provide a report indicating the percentage of the Fund’s income attributable to municipal securities and the portion thereof the interest on which is a tax preference item. In addition, for certain corporations, federal alternative minimum taxable income is increased by 75% of the difference between an alternative measure of income (“adjusted current earnings”) and the amount otherwise determined to be the alternative minimum taxable income. Interest on all municipal securities, and therefore all distributions by the Fund that would otherwise be tax-exempt, is included in calculating a corporation’s adjusted current earnings. Certain small corporations are not subject to the federal alternative minimum tax. Bonds issued in 2009 or 2010 generally will not be treated as private activity bonds, and interest earned on such bonds (and Fund distributions consisting of such interest) generally will not be treated as a tax preference item and generally will not result in or increase a corporate shareholder’s liability for the federal alternative minimum tax.

Tax-exempt income, including exempt-interest dividends paid by the Fund, is taken into account in calculating the amount of social security and railroad retirement benefits that may be subject to federal income tax.

The Fund’s investment in zero coupon bonds will cause it to realize income prior to the receipt of cash payments with respect to these bonds. Such income will be accrued daily by the Fund. In order to avoid a tax payable by the Fund, the Fund may be required to liquidate securities that it might otherwise continue to hold in order to generate cash so that the Fund may make required distributions to its shareholders.

Certain of the Fund’s investment practices are subject to special provisions of the Code that, among other things, may defer the use of certain deductions or losses of the Fund, affect the holding period of securities held by the Fund, and alter the character of the gains or losses realized by the Fund. These provisions may also require the Fund to recognize income or gain without receiving cash with which to make distributions in the amounts necessary to satisfy the requirements for maintaining RIC status and for avoiding income and excise taxes. The Fund will monitor its transactions and may make certain tax elections in order to mitigate the effect of these rules and prevent disqualification of the Fund for treatment as a regulated investment company.

Capital losses in excess of capital gains (“net capital losses”) are not permitted to be deducted against a RIC’s net investment income. Instead, for U.S. federal income tax purposes, potentially subject to certain limitations, the Fund may carry net capital losses from any taxable year forward to offset capital gains in future years. The Fund is permitted to carry forward a net capital loss from any taxable year that began on or before December 22, 2010 to offset its capital gains, if any, for up to eight years following the year of the loss. The Fund is permitted to carry forward indefinitely a net capital loss from any taxable year that began after December 22, 2010 to offset its capital gains, if any, in years following the year of the loss. To the extent subsequent capital gains are offset by such losses, they will not result in U.S. federal income tax liability to the Fund and may not be distributed as capital gains to shareholders. Carryforwards of losses from taxable years that began after December 22, 2010 must be fully utilized before the Fund may utilize carryforwards of losses from taxable years that began on or before December 22, 2010. Generally, the Fund may not carry forward any losses

other than net capital losses. Under certain circumstances, the Fund may elect to treat certain losses as though they were incurred on the first day of the taxable year immediately following the taxable year in which they were actually incurred.

The repurchase, sale or exchange of common shares normally will result in capital gain or loss to holders of common shares who hold their shares as capital assets. Generally a shareholder’s gain or loss will be long-term capital gain or loss if the shares have been held for more than one year even though the increase in value in such common shares may be at least partly attributable to tax-exempt interest income. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For noncorporate taxpayers, however, long-term capital gains are taxed at rates of up to 20%. Short-term capital gains and other ordinary income are taxed to noncorporate shareholders at ordinary income rates. If a shareholder sells or otherwise disposes of common shares before holding them for six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the Common Shareholder of long-term capital gain (including any amount credited to the shareholder as undistributed capital gain). Any loss realized on a sale or exchange of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced (including, without limitation, under the Plan) by substantially identical shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares, or to the extent the shareholder enters into a contract or option to repurchase shares within such period. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

The Fund is required in certain circumstances to withhold (as “backup withholding”) a portion of dividends (including exempt-interest dividends) and certain other payments paid to certain holders of the Fund’s shares who do not furnish to the Fund their correct taxpayer identification numbers (in the case of individuals, their social security numbers) and certain certifications, or who are otherwise subject to backup withholding. The backup withholding rate is 28%. Backup withholding is not an additional tax. Any amounts withheld from payments made to a shareholder may be refunded or credited against such shareholder’s federal income tax liability, provided the required information and forms are timely furnished to the IRS.

The Code provides that every shareholder required to file a tax return must include for information purposes on such return the amount of tax-exempt interest received during the taxable year, including any exempt-interest dividends received from the Fund.

The description of certain federal tax provisions above relates only to U.S. federal income tax consequences for shareholders who are U.S. persons, i.e., generally, U.S. citizens or residents or U.S. corporations, partnerships, trusts or estates, and who are subject to U.S. federal income tax and hold their shares as capital assets. Except as otherwise provided, this description does not address the special tax rules that may be applicable to particular types of investors, such as financial institutions, insurance companies, securities dealers, other regulated investment companies, or tax-exempt or tax-deferred plans, accounts or entities. Investors that are not U.S. persons may be subject to different U.S. federal income tax treatment, including a non-resident alien U.S. withholding tax at the rate of 30% or any lower applicable treaty rate on amounts treated as ordinary dividends from the Fund (other than, for taxable years of the Fund that begin on or before December 31, 2013, certain dividends reported by the Fund as (i) interest-related dividends, to the extent such dividends are derived from the Fund’s “qualified net-interest income,” or (ii) short-term capital gain dividends, to the extent such dividends are derived from the Fund’s “qualified short-term gain”) or, in certain circumstances, unless an effective IRS Form W-8BEN or other authorized withholding certificate is on file, to backup withholding on certain other payments from the Fund. “Qualified net interest income” is the Fund’s net income derived from U.S.-source interest and original issue discount, subject to certain exceptions and limitations. “Qualified short-term gain” generally means the excess of net short-term capital gain of the Fund for the taxable year over its net long-term capital loss, if any. Backup withholding will not be applied to payments that have been subject to the 30% (or lower applicable treaty rate) withholding tax on shareholders who are neither citizens nor residents of the United States.

Unless certain non-U.S. entities that hold Fund shares comply with IRS requirements that will generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to Fund distributions payable to such entities after December 31, 2013 (or, in certain cases, after later dates) and to repurchase proceeds and certain capital gain dividends payable to such entities after December 31, 2016. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of such agreement. Exempt-interest dividends may be exempt from this withholding tax.

The foregoing is a general summary of certain provisions of the Code and regulations thereunder presently in effect as they directly govern the federal income taxation of the Fund and its shareholders. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive. Moreover, the foregoing does not address many of the factors that may be determinative of whether an investor will be liable for the alternative minimum tax. Shareholders are advised to consult their own tax advisors for more detailed information concerning the federal, foreign, state and local tax consequences of purchasing, holding and disposing of Fund shares.

STATE AND LOCAL TAX MATTERS

The exemption from U.S. federal income tax for exempt-interest dividends generally does not result in exemption for such dividends under the income or other tax laws of any state or local taxing authority. In some states, however, the portion of any exempt-interest dividends derived from interest received by the Fund on its holdings of that state’s securities and its political subdivisions and instrumentalities is exempt from the state’s income tax. The Fund will report annually to its shareholders the percentage of interest income earned by the Fund during the preceding year on tax-exempt obligations indicating, on a state-by-state basis, the source of such income. Shareholders of the Fund are advised to consult with their own tax advisors about state and local tax matters.

APPENDIX A

Ratings of Investments

Standard & Poor’s Corporation—A brief description of the applicable Standard & Poor’s Corporation, a division of The McGraw-Hill Companies (“Standard & Poor’s” or “S&P”), rating symbols and their meanings (as published by S&P) follows:

A Standard & Poor’s issue credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion evaluates the obligor’s capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default. The issue credit rating is not a recommendation to purchase, sell, or hold a financial obligation, inasmuch as it does not comment as to market price or suitability for a particular investor.

Issue credit ratings are based on current information furnished by the obligors or obtained by Standard & Poor’s from other sources it considers reliable. Standard & Poor’s does not perform an audit in connection with any credit rating and may, on occasion, rely on unaudited financial information. Credit ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or based on other circumstances.

Issue credit ratings can be either long term or short term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days—including commercial paper. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. The result is a dual rating, in which the short-term rating addresses the put feature, in addition to the usual long-term rating. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based, in varying degrees, on the following considerations:

•

Likelihood of payment—capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

•

Nature of and provisions of the obligation;

•

Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

Issue ratings are an assessment of default risk, but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

AAA

An obligation rated ‘AAA’ has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

A-1

An obligation rated ‘AA’ differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

An obligation rated ‘A’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

BBB

An obligation rated ‘BBB’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC, CC, and C

Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

An obligation rated ‘BB’ is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

An obligation rated ‘B’ is more vulnerable to nonpayment than obligations rated ‘BB’, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.

CCC

An obligation rated ‘CCC’ is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

An obligation rated ‘CC’ is currently highly vulnerable to nonpayment.

A ‘C’ rating is assigned to obligations that are currently highly vulnerable to nonpayment, obligations that have payment arrearages allowed by the terms of the documents, or obligations of an issuer that is the subject of a bankruptcy petition or similar action which have not experienced a payment default. Among others, the ‘C’ rating may be assigned to subordinated debt, preferred stock or other obligations on which cash payments have been suspended in accordance with the instrument’s terms.

A-2

An obligation rated ‘D’ is in payment default. The ‘D’ rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor’s believes that such payments will be made during such grace period. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus (-)

The ratings from ‘AA’ to ‘CCC’ may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

This indicates that no rating has been requested, that there is insufficient information on which to base a rating, or that Standard & Poor’s does not rate a particular obligation as a matter of policy.

Short-Term Issue Credit Ratings

A-1

A short-term obligation rated ‘A-1’ is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2

A short-term obligation rated ‘A-2’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

A-3

A short-term obligation rated ‘A-3’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

A short-term obligation rated ‘B’ is regarded as having significant speculative characteristics. Ratings of ‘B-1’, ‘B-2’, and ‘B-3’ may be assigned to indicate finer distinctions within the ‘B’ category. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

B-1.

A short-term obligation rated ‘B-1’ is regarded as having significant speculative characteristics, but the obligor has a relatively stronger capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

B-2.

A short-term obligation rated ‘B-2’ is regarded as having significant speculative characteristics, and the obligor has an average speculative-grade capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

A-3

B-3.

A short-term obligation rated ‘B-3’ is regarded as having significant speculative characteristics, and the obligor has a relatively weaker capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

A short-term obligation rated ‘C’ is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.

A short-term obligation rated ‘D’ is in payment default. The ‘D’ rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor’s believes that such payments will be made during such grace period. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Dual Ratings

Standard & Poor’s assigns “dual” ratings to all debt issues that have a put option or demand feature as part of their structure. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term rating symbols are used for bonds to denote the long-term maturity and the short-term rating symbols for the put option (for example, ‘AAA/A-1+’). With U.S. municipal short-term demand debt, note rating symbols are used with the short-term issue credit rating symbols (for example, ‘SP-1+/A-1+’).

Moody’s Investors Service, Inc.—A brief description of the applicable Moody’s Investors Service, Inc. (“Moody’s”) rating symbols and their meanings (as published by Moody’s) follows:

Municipal Bonds

Aaa

Bonds that are rated ‘Aaa’ are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Bonds mat are rated ‘Aa’ are judged to be of high quality by all standards. Together with the ‘Aaa’ group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in ‘Aaa’ securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present mat make the long-term risks appear somewhat larger than in ‘Aaa’ securities.

Bonds that are rated ‘A’ possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

Baa

Bonds that are rated ‘Baa’ are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain

A-4

protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well.

Bonds that are rated ‘Ba’ are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

Bonds that are rated ‘B’ generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa

Bonds that are rated ‘Caa’ are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Bonds that are rated ‘Ca’ represent obligations that are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

Bonds that are rated ‘C’ are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor Prospects of ever attaining any real investment standing.

#(hatchmark): Represents issues that are secured by escrowed funds held in cash, held in trust, invested and reinvested in direct, non-callable, non-prepayable United States government obligations or non-callable, non-prepayable obligations unconditionally guaranteed by the U.S. Government, Resolution Funding Corporation debt obligations.

Con. (...): Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operation experience, (c) rentals that begin when facilities are completed, or (d) payments to which some other limiting condition attaches. The parenthetical rating denotes probable credit stature upon completion of construction or elimination of the basis of the condition.

(P): When applied to forward delivery bonds, indicates the rating is provisional pending delivery of the bonds. The rating may be revised prior to delivery if changes occur in the legal documents or the underlying credit quality of the bonds.

Note: Moody’s applies numerical modifiers 1,2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates mat the issue ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category.

Short-Term Loans

MIG 1/VMIG 1

This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

A-5

MIG 2/VMIG 2

This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3/VMIG 3

This designation denotes favorable quality. All security elements are accounted for but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

MIG 4/VMIG 4

This designation denotes adequate quality. Protection commonly regarded as required of an investment security is present and although not distinctly or predominantly speculative, there is specific risk.

This designation denotes speculative quality. Debt instruments in this category lack margins of protection.

Commercial Paper

Issuers (or supporting institutions) rated Prime-1 have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will normally be evidenced by the following characteristics:

•

Leading market positions in well-established industries.

•

High rates of return on funds employed.

•

Conservative capitalization structures with moderate reliance on debt and ample asset protection.

•

Broad margins in earnings coverage of fixed financial charges and high internal cash generation.

•

Well-established access to a range of financial markets and assured sources of alternate liquidity.

Issuers (or supporting institutions) rated Prime-2 have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above but to a lesser degree. Earnings trends and coverage ratios, while sound, may be more subject to variation than is the case for Prime-2 securities. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Issuers (or supporting institutions) rated Prime-3 have an acceptable ability for repayment of senior short-term debt obligations. The effect of industry characteristics and market composition may be more pronounced. Variability in earnings and profitability may result in changes in the level of debt protection measurements and the requirement for relatively high financial leverage. Adequate alternate liquidity is maintained.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Fitch Ratings—A brief description of the applicable Fitch Ratings (“Fitch”) ratings symbols and meanings (as published by Fitch) follows:

Long-Term Credit Ratings

Investment Grade

AAA

Highest credit quality. ‘AAA’ ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

A-6

Very high credit quality. ‘AA’ ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

High credit quality. ‘A’ ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB

Good credit quality. ‘BBB’ ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

Speculative Grade

Speculative. ‘BB’ ratings indicate that there is a possibility of credit risk developing, particularly as the result of adverse economic change over time; however, business or financial alternatives may be available to allow financial commitments to be met. Securities rated in this category are not investment grade.

Highly speculative. ‘B’ ratings indicate that significant credit risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is contingent upon a sustained, favorable business and economic environment.

CCC, CC, C

High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic developments. A ‘CC rating indicates that default of some kind appears probable. ‘C’ ratings signal imminent default.

DDD, DD, and D Default

The ratings of obligations in this category are based on their Prospects for achieving partial or full recovery in a reorganization or liquidation of the obligor. While expected recovery values are highly speculative and cannot be estimated with any precision, the following serve as general guidelines. ‘DDD’ obligations have the highest potential for recovery, around 90%-100% of outstanding amounts and accrued interest ‘DD’ indicates potential recoveries in the range of 50%-90%, and ‘D’ the lowest recovery potential, i.e., below 50%. Entities rated in this category have defaulted on some or all of their obligations. Entities rated ‘DDD’ have the highest Prospect for resumption of performance or continued operation with or without a formal reorganization process. Entities rated ‘DD’ and ‘D’ are generally undergoing a formal reorganization or liquidation process; those rated ‘DD’ are likely to satisfy a higher portion of their outstanding obligations, while entities rated ‘D’ have a poor Prospect for repaying all obligations.

Short-Term Credit Ratings

The following ratings scale applies to foreign currency and local currency ratings. A Short-term rating has a time horizon of less than 13 months for most obligations, or up to three years for US public finance, in line with

A-7

industry standards, to reflect unique risk characteristics of bond, tax, and revenue anticipation notes that are commonly issued with terms up to three years. Short-term ratings thus place greater emphasis on the liquidity necessary to meet financial commitments in a timely manner.

Highest credit quality. Indicates the strongest capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

Good credit quality. A satisfactory capacity for timely payment of financial commitments, but the margin of safety is not as great as in the case of the higher ratings.

Fair credit quality. The capacity for timely payment of financial commitments is adequate; however, near-term adverse changes could result in a reduction to non-investment grade.

Speculative Minimal capacity for timely payment of financial commitments, plus vulnerability to near-term adverse changes in financial and economic conditions.

High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon a sustained, favorable business and economic environment.

Default. Denotes actual or imminent payment default.

Notes to Long-term and Short-term ratings:

“+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the ‘AAA’ Long-term rating category, to categories below ‘CCC, or to Short-term ratings other than ‘FT.

‘NR’ indicates that Fitch Ratings does not rate the issuer or issue in question.

‘Withdrawn’: A rating is withdrawn when Fitch Ratings deems the amount of information available to be inadequate for rating purposes, or when an obligation matures, is called, or refinanced.

Rating Watch: Ratings are placed on Rating Watch to notify investors that there is a reasonable probability of a rating change and the likely direction of such change. These are designated as “Positive”, indicating a potential upgrade, “Negative”, for a potential downgrade, or “Evolving”, if ratings may be raised, lowered or maintained. Rating Watch is typically resolved over a relatively short period.

A Rating Outlook indicates the direction a rating is likely to move over a one to two year period. Outlooks may be positive, stable, or negative. A positive or negative Rating Outlook does not imply a rating change is inevitable. Similarly, ratings for which outlooks are ‘stable’ could be downgraded before an outlook moves to positive or negative if circumstances warrant such an action. Occasionally, Fitch Ratings may be unable to identify the fundamental trend. In these cases, the Rating Outlook may be described as evolving.

APPENDIX B

DERIVATIVE STRATEGIES AND RISKS

Set forth below is additional information regarding the various techniques involving the use of derivatives.

FINANCIAL FUTURES

A financial future is an agreement between two parties to buy and sell a security for a set price on a future date. They have been designed by boards of trade which have been designated “contracts markets” by the Commodity Futures Trading Commission (“CFTC”).

The purchase of financial futures is for the purpose of hedging the Fund’s existing or anticipated holdings of long-term debt securities. For example, if the Fund desires to increase its exposure to long-term bonds and has identified long-term bonds it wishes to purchase at a future time, but expects market interest rates to decline (thereby causing the value of those bonds to increase), it might purchase financial futures. If interest rates did decrease, the value of those to-be-purchased long-term bonds would increase, but the value of the Fund’s financial futures would be expected to increase at approximately the same rate, thereby helping maintain the Fund’s purchasing power. When the Fund purchases a financial future, it deposits in cash or securities an “initial margin”, typically equal to an amount between 1% and 5% of the contract amount. Thereafter, the Fund’s account is either credited or debited on a daily basis in correlation with the fluctuation in price of the underlying future or other requirements imposed by the exchange in order to maintain an orderly market. The Fund must make additional payments to cover debits to its account and has the right to withdraw credits in excess of the liquidity, the Fund may close out its position at any time prior to expiration of the financial future by taking an opposite position. At closing a final determination of debits and credits is made, additional cash is paid by or to the Fund to settle the final determination and the Fund realizes a loss or gain depending on whether on a net basis it made or received such payments.

The sale of financial futures is for the purpose of hedging the Fund’s existing or anticipated holdings of long-term debt securities. For example, if the Fund owns long-term bonds and market interest rates were expected to increase (causing those bonds’ values to decline), it might sell financial futures. If interest rates did increase, the value of long-term bonds in the Fund’s portfolio would decline, but the value of the Fund’s financial futures would be expected to increase at approximately the same rate thereby keeping the net asset value of the Fund from declining as much as it otherwise would have.

Among the risks associated with the use of financial futures by the Fund as a hedging or anticipatory device, perhaps the most significant is the imperfect correlation between movements in the price of the financial futures and movements in the price of the debt securities which are the subject of the hedge.

Thus, if the price of the financial future moves less or more than the price of the securities which are the subject of the hedge, the hedge will not be fully effective. To compensate for this imperfect correlation, the Fund may enter into financial futures in a greater dollar amount than the dollar amount of the securities being hedged if the historical volatility of the prices of such securities has been greater than the historical volatility of the financial futures. Conversely, the Fund may enter into fewer financial futures if the historical volatility of the price of the securities being hedged is less than the historical volatility of the financial futures.

The market prices of financial futures may also be affected by factors other than interest rates. One of these factors is the possibility that rapid changes in the volume of closing transactions, whether due to volatile markets or movements by speculators, would temporarily distort the normal relationship between the markets in the financial future and the chosen debt securities. In these circumstances as well as in periods of rapid and large price movements. The Fund might find it difficult or impossible to close out a particular transaction.

B-1

OPTIONS ON FINANCIAL FUTURES

The Fund may also purchase put or call options on financial futures which are traded on a U.S. Exchange or board of trade and enter into closing transactions with respect to such options to terminate an existing position. The purchase of put options on financial futures is analogous to the purchase of put options by the Fund on its portfolio securities to hedge against the risk of rising interest rates. As with options on debt securities, the holder of an option may terminate his position by selling an option of the Fund. There is no guarantee that such closing transactions can be effected.

INDEX CONTRACTS

INDEX FUTURES

A tax-exempt bond index which assigns relative values to the tax-exempt bonds included in the index is traded on the Chicago Board of Trade. The index fluctuates with changes in the market values of all tax-exempt bonds included rather than a single bond. An index future is a bilateral agreement pursuant to which two parties agree to take or make delivery of an amount of cash-rather than any security-equal to a specified dollar amount times the difference between the index value at the close of the last trading day of the contract and the price at which the index future was originally written. Thus, an index future is similar to traditional financial futures except that settlement is made in cash.

INDEX OPTIONS

The Fund may also purchase put or call options on U.S. Government or tax- exempt bond index futures and enter into closing transactions with respect to such options to terminate an existing position. Options on index futures are similar to options on debt instruments except that an option on an index future gives the purchaser the right, in return for the premium paid, to assume a position in an index contract rather than an underlying security at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance of the writer’s futures margin account which represents the amount by which the market price of the index futures contract, at exercise, is less than the exercise price of the option on the index future.

Bond index futures and options transactions would be subject to risks similar to transactions in financial futures and options thereon as described above.

SWAP AGREEMENTS

Swap agreements are two-party contracts entered into primarily by institutional investors, typically for periods ranging from a few weeks to several years. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or swapped between the parties are calculated with respect to a notional amount (the amount or value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) of a particular security, or in a basket of securities representing a particular index. Swap agreements may include, by way of example, (i) interest rate swaps, in which one party exchanges a commitment to pay a floating, shorter-term interest rate (typically by reference to the rate of a specific security or index) for the other party’s commitment to pay a fixed, longer-term interest rate (either as specifically agreed, or by reference to a specified security or index); (ii) interest rate caps, in which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate or cap; (iii) interest rate floors, in which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level or floor; (iv) interest rate collars, in which a party sells a cap and purchases a floor, or vice versa, in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels or collar amounts; (v) total return swaps, in which one party commits to pay the total return of an underlying security or asset in return for receiving from the other party a

B-2

specified return or the return of another instrument (typically a floating short-term interest rate), and (vi) credit default swap, in which the buyer pays a periodic fee in return for a contingent payment by the seller upon a credit event (such as a default) happening with respect to a specified instrument, typically in an amount equivalent to the loss incurred on a specific investment in that security due to the credit event.

A Fund may enter into such swap agreements for any purpose consistent with the Fund’s investment objective, such as for the purpose of attempting to obtain, enhance, or preserve a particular desired return or spread at a lower cost to the Fund than if the Fund had invested directly in an instrument that yielded that desired return or spread. The Fund also may enter into swaps in order to protect against an increase in the price of securities that the Fund anticipates purchasing at a later date.

Whether the Fund’s use of swap agreements will be successful in furthering its investment objective will depend, in part, on the ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments and the changes in the future values, indices, or rates covered by the swap agreement. Swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The Fund will enter swap agreements only with counterparties that the Adviser reasonably believes are capable of performing under the swap agreements. If there is a default by the other party to such a transaction, the Fund will have to rely on its contractual remedies (which may be limited by bankruptcy, insolvency or similar laws) pursuant to the agreements related to the transaction. Certain requirements imposed on the Fund by the Internal Revenue Code of 1986, as amended, may limit the Fund’s ability to use swap agreements. The swap market is largely unregulated.

Item 30:

Indemnification.

Section 4 of Article XII of the Registrant’s Declaration of Trust provides as follows:

Subject to the exceptions and limitations contained in this Section 4, every person who is, or has been, a Trustee, officer, employee or agent of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof.

No indemnification shall be provided hereunder to a Covered Person:

a. against any liability to the Trust or its Shareholders by reason of a final adjudication by the court or other body before which die proceeding was brought that he engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office;

b. with respect to any matter as to which he shall have been finally adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interests of the Trust; or

c. in the event of a settlement or other disposition not involving a final adjudication (as provided in paragraph (a) or (b)) and resulting in a payment by a Covered Person, unless there has been either a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office by the court or other body approving the settlement or other disposition or a reasonable determination, based on a review of readily available facts (as opposed to a full trial-type inquiry), that he did not engage in such conduct:

i. by a vote of a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter); or

ii. by written opinion of independent legal counsel.

The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be such a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such a person. Nothing contained herein shall affect any rights to indemnification to which Trust personnel other than Covered Persons may be entitled by contract or otherwise under law.

C-3

Expenses of preparation and presentation of a defense to any claim, action, suit or proceeding subject to a claim for indemnification under this Section 4 shall be advanced by the Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he is not entitled to indemnification under this Section 4, provided that either:

a. such undertaking is secured by a surety bond or some other appropriate security or the Trust shall be insured against losses arising out of any such advances; or

b. a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter) or independent legal counsel in a written opinion shall determine, based upon a review of the readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the recipient ultimately will be found entitled to indemnification.

As used in this Section 4, a “Disinterested Trustee” is one (x) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustee, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (y) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending.

As used in this Section 4, the words “claim,” “action,” “suit” or “proceeding” shall apply to all claims, actions, suits, proceedings (civil, criminal, administrative or other, including appeals), actual or threatened; and the words “liability” and “expenses” shall include without limitation, attorneys’ fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

The trustees and officers of the Registrant are covered by Investment Trust Directors and Officers and Errors and Omission policies in the aggregate amount of $50,000,000 (with a maximum deductible of $1,000,000 for cost of correction and $2,500,000 for all other claims) against liability and expenses of claims of wrongful acts arising out of their position with the Registrant, except for matters that involve willful acts, bad faith, gross negligence and willful disregard of duty (i.e., where the insured did not act in good faith for a purpose he or she reasonably believed to be in the best interest of the Registrant or where he or she had reasonable cause to believe this conduct was unlawful). The policy has a $1,000,000 deductible for operational failures (after the deductible is satisfied, the insurer would cover 80% of any operational failure claims and the Fund would be liable for 20% of any such claims) and $1,000,000 deductible for all other claims, with $0 deductible for individual insureds.

Section 8 of the Form of Distribution Agreement filed as Exhibit h.1 to this Registration Statement provides for each of the parties thereto, including the Registrant and the Agent, to indemnify the others, their trustees, directors, certain of their officers, trustees, directors and persons who control them against certain liabilities in connection with the offering described herein, including liabilities under the federal securities laws.

Insofar as indemnification for liability arising under the Securities Act of 1933 (the “1933 Act”) may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.
