PRELIMINARY PROSPECTUS

2.5 Million Shares

Nuveen California Municipal Value Fund, Inc.

Common Stock

Nuveen California Municipal Value Fund, Inc. (the “Fund”) is a diversified, closed-end management investment company. The Fund’s primary investment objective is to provide current income exempt from regular federal and California income taxes. The Fund’s secondary investment objective is to enhance portfolio value relative to the California municipal bond market by investing in tax-exempt California municipal securities that Nuveen Fund Advisors, LLC (“NFALLC”), the Fund’s investment adviser, believes are underrated or undervalued or that represent municipal market sectors that are undervalued. The Fund seeks to achieve its investment objectives by investing, under normal circumstances, at least 80% of its Managed Assets (as defined below under Portfolio Contents ) in investments the income from which is exempt from regular federal and California income tax. Under normal circumstances, the Fund invests at least 80% of its Managed Assets in municipal securities that at the time of investment are rated within the four highest grades by at least one 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 cannot assure you that it will achieve its investment objectives.

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

Neither the U.S. Securities and Exchange Commission (the “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 dated March 1, 2013, ( the “SAI”), 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).

Shares of the Fund’s common stock 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.     As a fundamental policy, under normal circumstances, the Fund invests at least 80% of its Managed Assets (as defined below) in municipal securities and other related investments the income from which is exempt from regular federal and California income tax. The Fund invests in tax-exempt municipal

securities that NFALLC believes are underrated or undervalued or that represent municipal market sectors that are undervalued. The Fund has not established any limit on the percentage of its portfolio that may be invested in municipal bonds subject to the alternative minimum tax provisions of federal tax law, and the Fund expects that a substantial portion of the income it produces will be includable in alternative minimum taxable income. As a non-fundamental policy, under normal circumstances, the Fund invests at least 80% of its Managed Assets in municipal securities that at the time of investment are investment grade quality. 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. The Fund may invest up to approximately 10% of its Managed Assets in inverse floating rate securities. “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.

No Preferred Shares.     Unless otherwise approved by shareholders, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments. However, the Fund may borrow for temporary, emergency or other purposes as permitted by the Investment Company Act of 1940, as amended. In addition, the Fund may invest in certain instruments, including inverse floating rate securities, that have the economic effect of financial leverage. The degree of economic leverage associated with the Fund’s investment in such securities is generally greater than the percentage of the Fund’s net assets invested in those securities.

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.

The minimum price on any day at which shares of common stock may be sold will not be less than the current net asset value per share plus the per share amount of the commission to be paid to the Fund’s distributor, Nuveen Securities, LLC (“Nuveen Securities”). The Fund and Nuveen Securities will suspend the sale of common stock 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 stock may be sold, see the “Plan of Distribution” section of this Prospectus.

Shares of common stock are listed on the New York Stock Exchange (the “NYSE”). The trading or “ticker” symbol of the Fund’s common stock is “NCA.” The Fund’s closing price on the NYSE on                 , 2013 was $        .

You should rely only on the information contained or incorporated by reference into this Prospectus. The Fund has not authorized anyone to provide you with different information. The Fund is not making an offer of these securities in any state where the offer is not permitted. You should not assume that the information contained in this Prospectus is accurate as of any date other than the date on the front of this Prospectus. The Fund will update this Prospectus to reflect any material changes to the disclosures herein.

THE FUND’S INVESTMENTS

Investment Objectives

The Fund’s investment objectives are:

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.

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 for Diversification.     As of September 30, 2012, the municipal securities market aggregated approximately $3.7 trillion, with approximately 55,000 issuers, and a wide array of financing purposes, security terms, offering structures and credit quality.

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, value-oriented 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.

19

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.

Diversification.     Nuveen Asset Management seeks to invest in a large number of sectors and specific issuers in order to help insulate a portfolio from events that affect any individual industry or credit.

Portfolio managers normally seek to limit exposure to individual credits over the long-term. Portfolio managers also seek to diversify other portfolio level risks, including 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. Nuveen Asset Management may also sell securities when such securities exceed the portfolio’s diversification targets.

Investment Policies

Under normal circumstances, the Fund will invest its Managed Assets in a portfolio of municipal securities that pay interest that is exempt from regular and California federal income tax. It is a fundamental policy that, under normal circumstances, 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 and California income taxes. The Fund has not established any limit on the percentage of its portfolio that may be invested in municipal bonds subject to the alternative minimum tax provisions of federal tax law, and the Fund expects that a substantial portion of the income it produces will be includable in alternative minimum taxable income. For a discussion of how the federal alternative minimum tax may affect shareholders, see “Tax Matters.” As a fundamental policy, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments. However, the Fund may borrow for temporary, emergency or other purposes as permitted by the 1940 Act, and invest in certain instruments, including inverse floating rate securities, that have the economic effect of financial leverage.

As a non-fundamental policy, under normal circumstances, 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 nationally recognized statistical rating organizations (“NRSRO”) that rate such security or are unrated 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. The Fund may invest up to approximately 15% of its Managed Assets in inverse floating rate securities (discussed below). The economic effect of leverage through the Fund’s purchase of inverse floating rate securities creates an opportunity for increased net income and returns, but also creates the possibly that the Fund’s long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund. The Fund’s policy of investing under normal market circumstances at least 80% of its Managed Assets in municipal securities that, at the time of investment, are investment grade quality is not considered to be fundamental by the Fund and can be changed

20

without stockholder approval. However, this policy may only be changed by the Fund’s Board following the provision of 60 days’ prior notice to Common Stockholders.

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 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.

The ratings of 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”) 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 foregoing credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that an NRSRO downgrades its assessment of the credit characteristics of a particular issuer or that valuation changes of various bonds cause the Fund’s portfolio to fail to satisfy those policies. 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. See “Municipal Securities” below. The Fund may also invest in securities of other open- or closed-end investment companies (up to 10% of its Managed Assets) that invest primarily in municipal bonds of the types in which the Fund may invest directly. See “Other Investment Companies” below.

Underrated municipal securities are those whose ratings do not, in NFALLC’s opinion, reflect their true value. Municipal securities may be underrated because of the time that has elapsed since their rating was assigned or reviewed, or because of positive factors that may not have been fully taken into account by rating agencies, or for other similar reasons. Municipal securities that are undervalued or that represent undervalued municipal market sectors are municipal securities that, in NFALLC’s opinion, are worth more than the value assigned to them in the marketplace. Municipal securities of particular types or purposes ( e.g. , hospital bonds, industrial revenue bonds or bonds 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. The Fund’s investment in underrated or undervalued California municipal securities will be based on NFALLC’s belief that the prices of such municipal securities should ultimately reflect their true value. Accordingly, “enhancement of portfolio value relative to the California municipal bond market” refers to the Fund’s objective of attempting to realize above-average capital appreciation in a rising market, and to experience less than average capital losses in a declining market. Thus, the Fund’s secondary investment

21

objective is not intended to suggest that capital appreciation is itself an objective of the Fund. Instead, the Fund seeks enhancement of portfolio value relative to the California municipal bond market by prudent selection of California municipal securities, regardless of which direction the market may move.

Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to Common Stockholders. The Fund has not established any limit on the percentage of its portfolio that may be invested in municipal bonds subject to the alternative minimum tax provisions of federal tax law, and the Fund expects that a substantial portion of the income it produces will be includable in alternative minimum taxable income.

The Fund will primarily invest in California municipal securities with long-term maturities in order to maintain a weighted average maturity of at least 15, but the average weighted maturity of obligations held by the Fund may be shortened, depending on market conditions. As of                 , 2013, the weighted average maturity of the Fund’s portfolio was          years. As a result, the Fund’s portfolio at any given time may include both long-term and intermediate-term California municipal securities. Moreover, during temporary defensive periods ( e.g. , times when, in NFALLC’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt bond 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, the Fund may invest any percentage of its net assets in short-term investments including high quality, short-term debt 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 objective during such period. Investment in taxable short-term investments would result in a portion of your dividends being subject to regular federal or California 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.

The Fund may purchase municipal securities that are additionally secured by insurance, bank credit agreements, or escrow accounts. The credit quality of companies which provide such credit enhancements may affect the value of those securities. Although the insurance feature may reduce certain financial risks, the premiums for insurance and the higher market price paid for insured obligations may reduce the Fund’s income. The insurance feature does not guarantee the market value of the insured obligations, and the effectiveness and value of the insurance itself is dependent on the continued creditworthiness of the insurer.

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.

The Fund cannot change its investment objectives without the approval of the holders of a “majority of the outstanding” shares of Common Stock. See “Description of Shares—Common Stock.

As of February 28, 2013, approximately     % of the Fund’s Managed Assets were invested in municipal 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.

22

The Fund is diversified for purposes of the 1940 Act. Consequently, as to 75% of its assets, the Fund may not invest more than 5% of its total assets in the securities of any single issuer.

Municipal Securities

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 (as previously defined, “municipal securities”). 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.

California municipal securities are municipal securities that are issued by the State of California and cities and local authorities in the State of California, and bear interest that, in the opinion of bond counsel to the issuer, is exempt from both regular federal and California income taxes, although such interest may be subject to the Federal alternative minimum tax. The Fund will invest primarily in California municipal securities that are issued by the State of California and cities and local authorities in the State of California, except that the Fund may invest not more than 10% of its net assets in municipal securities issued by United States possessions or territories, which also bear interest that is exempt from both regular federal and California income taxes and are therefore considered to be California municipal securities.

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 and California income tax.

The municipal securities in which the Fund will invest are generally issued by the State of California, a municipality of California, or a political subdivision of either, 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 and California personal income taxes, although the interest may be subject to the federal alternative minimum tax. The Fund may invest in municipal securities issued by U.S. territories (such as Puerto Rico or Guam) that are exempt from regular federal and California income taxes.

23

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.

The Fund will primarily invest in California municipal securities with long-term maturities in order to maintain a weighted average maturity of at least 15 years, but the weighted average maturity of obligations held by the Fund may be shorter, depending on market conditions. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments and call features in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration.

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.

24

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.

Inverse Floating Rate Securities.     The Fund may invest up to approximately 10% of its Managed Assets in inverse floating rate securities. Inverse floating rate securities (sometimes referred to as “inverse floaters” or residual interests of a tender option bond) 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: short-term floating rate municipal securities (sometimes referred to as short-term floaters or tender option bonds), which are sold to third party investors, and inverse floating rate municipal securities, which the Fund would purchase. 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

25

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, an institution 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 face value of the short-term floaters in relation to the residual inverse floaters that are issued by the special purpose trust. The higher the percentage of the special purpose trust’s total value represented by the short-term floaters, the greater the effective leverage. For example, if municipal bonds worth $100 are deposited in a special purpose trust and the trust issues short-term floaters worth $75 and inverse floaters worth $25, the trust will have a leverage ratio of 3:1 and the inverse floaters will exhibit price movements at a rate that is four times that of the underlying bonds deposited into the trust. If that same trust were to issue only $50 of floaters, the leverage ratio would be 1:1 and the inverse floaters would exhibit price movements at a rate that is only two times that of the underlying bonds. The Fund expects to make limited investments in inverse floaters, with leverage ratios that may vary 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, inverse floaters’ value are more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is generally more volatile than the underlying bonds 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 out-perform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for 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 bonds 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 NFALLC’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. 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.

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.

26

Investments in inverse floating rate securities create effective leverage. The use of leverage creates special risks for Common Stockholders. See “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.

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 (the “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 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

27

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. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund and, to the extent distributed, will be taxable distributions to shareholders. The Fund may enter into contracts to purchase municipal bonds 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.

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.

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.

Special Considerations Relating to California Municipal Securities

As described above, the Fund will invest at least 80% of its Managed Assets in California municipal securities and other related investments, the income from which is exempt from regular federal and California personal income tax. The Fund is therefore susceptible to political, economic or regulatory factors affecting issuers of California municipal securities. See “Concentration Risk in California Issuers” and Appendix A of this Prospectus (“Factors Affecting Municipal Securities in California”). Information regarding the financial condition of the State of California is ordinarily included in various public documents issued thereby, such as the official statements prepared in connection with the issuance of general obligation bonds of the State of California. Such official statements may be obtained by contacting the State Treasurer’s Office at 800-900-3873 or at www.treasurer.ca.gov. Complete text of the 2013-2014 budget, and prior budgets, may be found at the electronic budget website of the Department of Finance (www.ebudget.ca.gov).

The State of California is a party to numerous legal proceedings, many of which normally occur in governmental operations. Information regarding some of the more significant litigation pending against the State would ordinarily be included in various public documents issued thereby, such as the official statements referred to above prepared in connection with the issuance of general obligation bonds of California.

The Legislative Analyst’s Office (the “LAO”) has released several reports which include their estimates and assessments of State budget acts and associated fiscal and economic projections. Publications from the LAO can be read in full by accessing the LAO’s website (www.lao.ca.gov) or by contacting the LAO at 916-445-4656. Information on the website is not incorporated herein by reference. Complete text of the State Controller’s monthly Summary Analysis may be accessed at the State Controller’s website (www.sco.ca.gov).

It should be noted that the creditworthiness of obligations issued by local California issuers may be unrelated to the creditworthiness of obligations issued by the State of California, and that there is no obligation on the part of the State of California to make payment on such local obligations in the event of default. See “Concentration Risk in California Issuers” and Appendix A of this Prospectus (“Factors Pertaining to California”).

None of the information on the above websites is incorporated herein by reference.

Derivatives

The Fund may invest in certain derivative instruments in pursuit of its investment objectives. 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. The Fund may use also 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

29

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.

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.

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 took effect on 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.

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 the offering of its Common Stock, 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 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 received or applied for, nor does it currently intend to apply for, any 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.

30

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 Stockholders 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 California 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          % under normal circumstances. 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.”

PORTFOLIO COMPOSITION

As of February 28, 2013, 100% of the market value of the Fund’s portfolio was invested in long-term municipal bonds. The following table sets forth certain information with respect to the composition of the Fund’s investment portfolio as of February 28, 2013.

USE OF LEVERAGE

Financial leverage is created through 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. See “The Fund’s Investments—Municipal Securities—Inverse Floating Rate Securities” and “Risk Factors—Inverse Floating Rate Securities.” Leverage involves special risks. There is no assurance that the Fund’s leveraging

31

strategy will be successful. The Fund will seek to invest the proceeds from financial leverage in a manner consistent with the Fund’s objectives and policies.

The Fund’s investments in inverse floating rate securities pay dividends at rates based on short-term periods which are reset periodically. So long as the Fund’s portfolio is invested in securities that provide a higher rate of return than the Fund’s cost of leverage (after taking expenses into consideration), the leverage will cause you to receive a higher current rate of return than if the Fund were not leveraged.

Changes in the value of the Fund’s bond portfolio will be borne entirely by the Common Stockholders. If there is a net decrease (or increase) in the value of the Fund’s investment portfolio, the leverage will decrease (or increase) the net asset value per share of Common Stock to a greater extent than if the Fund were not leveraged.

The Fund pays NFALLC a management fee based on a percentage of Managed Assets. Managed Assets for this purpose includes the proceeds realized from the Fund’s use of financial leverage. See “Management of the Fund—Investment Management Agreement.” 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 Managed 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 Directors.

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 Stock.

Investment and Market Risk

An investment in the Fund’s Common Stock is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Common Stock represents an indirect investment in the municipal securities owned by the Fund, which generally trade in the over-the-counter markets. Your Common Stock 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.

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

32

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 quasigovernmental organizations. In addition, on August 5, 2011, S&P lowered its long-term sovereign credit rating on the U.S. federal government debt to “AA+” from “AAA.” The downgrade by S&P could increase volatility in both stock and bond markets, result in higher interest rates and higher U.S. Treasury yields and increase the costs of all kinds of debt. These events could have significant adverse effects on the economy generally.

Market Discount from 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. The Fund cannot predict whether shares of Common Stock 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 Stock 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 shares of Common Stock at the time of any offering of Common Stock 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 0.    % of the offering price assuming a Common Stock share offering price of $         (the Fund’s closing price on the NYSE on                 , 2013)). The shares of Common Stock 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. 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. 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

33

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:

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 Stock. 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

34

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 Stock 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 also tend to increase Common Stock 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

35

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 market price of the shares of Common Stock or their overall returns.

Concentration Risk in California Issuers

The Fund’s policy of investing in municipal securities of issuers located in California makes the Fund more susceptible to the adverse economic, political or regulatory occurrences affecting such issuers. The information set forth below and the related information in Appendix A of this Prospectus is derived from sources that are generally available to investors. The information is intended to give a recent historical description and is not intended to indicate future or continuing trends in the financial or other positions of California. It should be noted that the creditworthiness of obligations issued by local California issuers may be unrelated to the creditworthiness of obligations issued by the State of California, and that there is no obligation on the part of the State to make payment on such local obligations in the event of default.

The State of California, as the rest of the nation, has been slowly emerging from an economic recession that began at the end of 2007, marked in California by high unemployment, a steep contraction in housing construction and home values, a drop in State-wide assessed valuation of property for the first time on record, a year-over-year decline in personal income in the State for the first time in 60 years, and a sharp drop in taxable sales. The State is recovering more slowly than expected and continues to face significant financial challenges.

California’s budget problems have been driven in part by large fluctuations in its tax revenue and fixed spending obligations. During recessionary periods, dramatic cuts to programs and/or tax increases sometimes have been required. To address budget gaps, spending has been cut, State programs have been realigned to local governments, and short-term budgetary solutions have been implemented. Budget gaps are expected, however, to continue to challenge State fiscal leaders in future years. Continued risks to the State’s long-term stability include pension liabilities, debt and increasing annual obligations, and potential cost increases associated with the federal deficit.

California’s fiscal situation heightens the risk of investing in bonds issued by the State and its political subdivisions, agencies, instrumentalities and authorities, including the risk of default, and also heightens the risk that the prices of California municipal securities, and the fund’s net asset value, will experience greater volatility. As of November 2012, California general obligation bonds were rated A1 by Moody’s and A- by S&P and Fitch.

36

These ratings are among the lowest of any of the 50 states. There can be no assurance that such ratings will be maintained in the future. The State’s credit rating, and any future revisions or withdrawal of a credit rating, could have a negative effect on the market price of the State’s general obligation bonds, as well as notes and bonds issued by California’s public authorities and local governments. Lower credit ratings make it more expensive for the State to raise revenue, and in some cases, could prevent the State from issuing general obligation bonds in the quantity otherwise desired. Further, downgrades can negatively impact the marketability and price of securities in the fund’s portfolio.

The foregoing information constitutes only a brief summary of some of the general factors that may impact certain issuers of municipal bonds and does not purport to be a complete or exhaustive description of all adverse conditions to which the issuers of municipal bonds held by the Fund are subject. Additionally, many factors, including national economic, social and environmental policies and conditions, which are not within the control of the issuers of the municipal bonds, could affect or could have an adverse impact on the financial condition of the issuers. The Fund is unable to predict whether or to what extent such factors or other factors may affect the issuers of the municipal securities, the market value or marketability of the municipal securities or the ability of the respective issuers of the municipal bonds acquired by the Fund to pay interest on or principal of the municipal securities. This information has not been independently verified. See Appendix A of this Prospectus for a further discussion of factors affecting municipal securities in California.

Inverse Floating Rate Securities Risk

The Fund may invest up to approximately 10% 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

37

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 Stock net income and returns, but will also create the possibility that Common Stock 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 Stock 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:

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

38

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 Stock 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.

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 a 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.

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.”

39

Borrowing Risks

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.

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 shares of Common Stock 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 Stockholders.

Economic Sector Risk

The Fund may invest 25% or more of its total assets in municipal securities in the same economic sector. This may make the Fund more susceptible to adverse economic, political or regulatory occurrences affecting an economic sector. As concentration increases, so does the potential for fluctuation in the value of the Fund’s assets.

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.

40

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, “—Counterparty Risk,” “—Hedging Risk” and the Statement of Additional Information.

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.

41

Illiquid Securities Risk

The Fund may invest 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.

Call Risk

If interest rates fall, it is possible that issuers of callable bonds with higher interest coupons will “call” (or prepay) their bonds before their maturity date. If a call were exercised by the issuer during a period of declining interest rates, the Fund is likely to replace such called security with a lower yielding security.

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 Stock through the various methods described in the Prospectus may have an adverse effect on prices in the secondary market for the Fund’s Common Stock by increasing the number of shares of Common Stock available for sale. In addition, the shares of Common Stock may be issued at a discount to the market price for such shares, which may put downward pressure on the market price for shares of Common Stock 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. 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 Stock, the Fund will be precluded from effecting principal transactions with brokers who are members of the syndicate.

Anti-Takeover Provisions

The Fund’s Articles 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 Stockholders of opportunities to sell their shares of Common Stock at a premium over the then current market price of the shares of Common Stock. See “Certain Provisions in the Articles of Incorporation.”

42

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” shares of Common Stock.

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, 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 nationally recognized statistical rating organizations (“NRSRO”) that rate such security or are unrated but judged to be of comparable quality by Nuveen Asset Management.

No Preferred Shares

Unless otherwise approved by shareholders, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments. However, the Fund may borrow for temporary, emergency or other purposes as permitted by the 1940 Act and invest in certain instruments, including inverse floating rate securities, that have the economic effect of financial leverage.

Hedging Strategies

The Fund may use various investment strategies designed to limit the risk of bond price fluctuations and to preserve capital. These hedging strategies include using credit default swaps, interest-rate swaps on taxable and tax-exempt indices, forward starting rate swaps and options on interest rate swaps, financial futures contracts, options on financial futures or options based on either an index of long-term municipal securities or on taxable debt securities whose prices, in the opinion of Nuveen Asset Management, correlate with the prices of the Fund’s investments. These hedging strategies may generate taxable income.

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 Fund pays an annual fund-level fee, payable monthly, of .15% of the average daily net assets of the Fund, as well as 4.125% of the gross interest income (excluding interest on bonds underlying a “self-deposited inverse floater” trust that is attributed to the Fund over and above the net interest earned on the inverse floater itself) of the Fund.

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

44

In addition to the fee of NFALLC, the Fund pays all other costs and expenses of its operations, including compensation of its directors (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 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.

Sub-Advisory Agreement.     Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management will receive from NFALLC a management fee equal to 71.4286% of NFALLC’s net management fee from the Fund.

A discussion regarding the basis for the Board of Directors’ decision to approve the Investment Management Agreement and Sub-Advisory Agreement may be found in the Fund’s semi-annual report to shareholders for the period ended August 31, 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 Directors 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 Directors. 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 Directors of the Fund, or its designee, may establish fair market value using a

45

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 Directors’ 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 Stockholders at a level rate (stated in terms of a fixed cents per Common Stock 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.

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. Common Stockholders of record as of the end of the Fund’s taxable year will include their attributable share of the retained net capital gain in their income for the year as a long-term capital gain (regardless of their holding period in the Common Stock), will be deemed to have paid their proportionate shares of tax paid by the Fund, and will be entitled to income tax credits or refunds for the tax deemed paid on their behalf by the Fund. 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. A return of capital reduces a Stockholder’s tax basis which could result in higher taxes when the Stockholder sells his or her stocks. This may cause the Stockholder to pay taxes even if he or she sells stocks for less than the original price.

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 shares of Common Stock are registered directly with the Fund or if you hold your shares of Common Stock 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 Stock automatically reinvested by the Plan Agent (defined below) in additional Common Stock 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 shares of Common Stock you will receive will be determined as follows:

(1) If shares of Common Stock 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;

46

(2) If shares of Common Stock 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 shares of Common Stock in the open market, on the NYSE or elsewhere, for the participants’ accounts. It is possible that the market price for the shares of Common Stock 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 shares of Common Stock issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase shares of Common Stock 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 the Fund’s shares purchased on or after January 1, 2012 (“covered shares”).

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.

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

There is no brokerage charge for reinvestment of your dividends or distributions in shares of Common Stock. 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 Stock 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 Directors 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.

PLAN OF DISTRIBUTION

The Fund may sell the Common Stock offered under this Prospectus through

The Fund will bear the expenses of the offering, including but not limited to, the expenses of preparation of the Prospectus and SAI for the offering and the expense of counsel and auditors in connection with the offering.

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 from time to time offer its Common Shares through Nuveen Securities to certain broker-dealers which have entered into selected dealer agreements with Nuveen Securities. Currently, Nuveen Securities has entered into an Equity Distribution Agreement (the “Selected Dealer Agreement”) with Stifel, Nicolaus & Company, Incorporated (“Stifel Nicolaus”), pursuant to which Stifel Nicolaus will act as the exclusive sub-placement agent with respect to at-the-market offerings of the Common Stock. A form of the Selected Dealer Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part. The summary of the Selected Dealer Agreement contained herein is qualified by reference to the Selected Dealer Agreement.

Common Stock will only be sold on such days as shall be agreed to by the Fund, Nuveen Securities and Stifel Nicolaus. Common Stock 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 Nuveen Securities. The minimum price on any day will not be less than the current net asset value per share of Common Stock plus the per share amount of the commission to be paid to Nuveen Securities. Nuveen Securities and Stifel Nicolaus will suspend the sale of Common Stock 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 Common Stock at a commission rate of 1.0% of the gross proceeds of the sale of Common Stock. Nuveen Securities will compensate Stifel Nicolaus at a fixed rate of 0.8% of the gross proceeds of the sale of Common Stock sold by Stifel Nicolaus. Settlements of sales of Common Stock 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 Stock 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 Prospectus supplement, Nuveen Securities and Stifel Nicolaus will act on a reasonable efforts basis.

The offering of Common Stock pursuant to the Selected Dealer Agreement will terminate upon the earlier of (i) the sale of all Common Stock subject thereto or (ii) termination of the Selected Dealer Agreement. Each of Nuveen Securities and Stifel Nicolaus has the right to terminate the Selected Dealer Agreement in its discretion at any time.

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             , 2013 was $        .

48

Distribution Through Underwriting Syndicates

The Fund from time to time may issue additional Common Stock through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s shares of Common Stock, 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.

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 shares of Common Stock 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 Stock. 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 share of Common Stock or (ii) 91% of the closing market price of the shares of the Fund’s Common Stock on the day prior to the offering date.

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 Stock.

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 Stock 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 Stock, the purchase price to apply to any such sale of Common Stock and the person seeking to purchase the Common Stock.

Shares of Common Stock 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 share of the Fund’s Common Stock or (ii) at a discount ranging from 0% to 5% of the average daily closing market price of the Fund’s Common Stock at the close of business on the two business days preceding the date upon which shares of Common Stock are sold pursuant to the privately negotiated transaction. 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 Stock

The Fund’s Articles of Incorporation authorize the issuance of 250,000,000 shares of common stock. All shares of common stock have equal rights to the payment of dividends and the distribution of assets upon liquidation. Shares of common stock are, when issued, fully paid and non-assessable, and have no pre-emptive or conversion rights except as the directors may determine or rights to cumulative voting. Each share of Common Stock 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. Each whole share of Common Stock shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional share shall be entitled to a proportional fractional vote. The Fund pays monthly dividends, typically on the first business day of the following month.

49

The Fund’s common stock is listed on the NYSE. The Fund intends to hold annual meetings of stockholders so long as the Fund’s shares are listed on a national securities exchange and such meetings are required as a condition to such listing.

Unlike open-end funds, closed-end funds like the Fund do not provide daily redemptions. Rather, if a shareholder determines to buy additional Common Stock 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 Stock 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 Stock will trade at a price equal to or higher than net asset value in the future. The Common Stock are designed primarily for long-term investors, and investors in the Common Stock should not view the Fund as a vehicle for trading purposes. See “Repurchase of Fund Shares; Conversion to Open-End Fund.”

The Fund may borrow money for repurchase of its shares or as a temporary measure for extraordinary or emergency situations. See “Investment Restrictions” in the Statement of Additional Information.

Other Shares

The Fund is currently authorized to issue only shares of Common Stock.

CERTAIN PROVISIONS IN THE ARTICLES OF INCORPORATION

Stockholder and Director Liability .    Under the Minnesota Business Corporation Act, a subscriber for shares or a shareholder of a corporation is under no obligation to the corporation or its creditors with respect to the shares subscribed for or owned, except to pay the corporation the full agreed-upon consideration for the shares. However, a shareholder who receives a distribution which is made in violation of the Minnesota Business Corporation Act’s limitations on distributions is liable to the corporation to the extent that the distribution exceeded the amount that properly could have been paid.

The Articles of Incorporation provide that the Fund’s obligations are not binding upon the Fund’s directors individually, but only upon the Fund’s assets and property and provide for the indemnification of directors individually by the Fund for certain liabilities arising out of the performance of their duties to the Fund to the maximum extent permitted under Minnesota law. Nothing in the Articles of Incorporation, however, protects a director against any liability to which he or she 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 or her office.

Anti-Takeover Provisions.     The Fund’s Articles of Incorporation include provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund. Specifically, the Articles require the affirmative vote of the holders of at least 66  ² / ₃ % of the Fund’s outstanding shares of Common Stock then entitled to be voted to authorize any of the following transactions:

50

unless such action has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of directors fixed in accordance with the By-Laws. The 66  ² / ₃ % vote required under certain circumstances to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve the other transactions described above are higher than those required by the 1940 Act. The Board of Directors 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 Directors. See the SAI under “Certain Provisions in the Articles of Incorporation.”

The provisions of the Articles of Incorporation described above could have the effect of depriving the Common Stockholders of opportunities to sell their shares of Common Stock at a premium over the then current market price of the shares of Common Stock 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 objectives and policies. The Board of Directors 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 Stockholders.

Reference should be made to the Articles 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 stockholders will not have the right to cause the Fund to redeem their shares. Instead, the shares of Common Stock 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 Directors 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 shares of Common Stock, 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 Directors 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, shares of Common Stock 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 Articles of Incorporation” 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 shares of Common Stock 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 Directors 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

51

action to reduce or eliminate such discount to net asset value. On November 16, 2011, the Fund’s Board of Directors 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 repurchased              shares of Common Stock 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 has elected and intends to qualify each year to be treated as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (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 taxable to noncorporate taxpayers at rates of up to 20%. 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 is taxable to noncorporate shareholders at reduced maximum U.S. federal income tax rates.

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.

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

52

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 shares of Common Stock normally will result in capital gain or loss to holders of Common Stock 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 shares of Common Stock 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 taxpayers at ordinary income rates. If a shareholder sells or otherwise disposes of shares of Common Stock 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 Stockholder of long-term capital gain (including any amount credited to the Common Stockholder 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.

California Tax Matters

The Fund’s regular monthly dividends will not be subject to California personal income tax to the extent they are paid out of income earned on obligations that, when held by individuals, pay interest that is exempt from taxation by California under California law ( e.g. , obligations of California and its political subdivisions) or federal law, so long as at the close of each quarter of the Fund’s taxable year at least 50% of the value of the Fund’s total assets consists of such obligations and the Fund designates such tax-exempt distributions pursuant to certain written notice requirements to its shareholders. The portion of the Fund’s monthly dividends that is attributable to income other than as described in the preceding sentence will be subject to the California income tax. The Fund expects to earn no or only a minimal amount of such non-exempt income. If you are an individual California resident, you will be subject to California personal income tax to the extent the Fund distributes any realized capital gains, or if you sell or exchange shares and realize a capital gain on the transaction.

Other State and Local Tax Matters

While exempt-interest dividends are exempt from regular federal and California income taxes, they may not be exempt from other state or local income or other taxes. Some states exempt from state income tax that portion of any exempt-interest dividend that is derived from interest a regulated investment company receives on its holdings of securities of that state and its political subdivisions and instrumentalities. Therefore, the Fund will report annually to its shareholders the percentage of interest income the Fund earned during the preceding year on tax-exempt obligations and the Fund will indicate, on a state-by-state basis, the source of this income. Shareholders are advised to consult with their own tax advisors for more detailed information concerning California tax matters or the tax laws of their state and locality of residence. Please refer to the Statement of Additional Information for more detailed information.
