Alliance National Municipal Income Fund Semi-Annual Report April 30, 2003 [LOGO] ALLIANCEBERNSTEIN Investment Research and Management Investment Products Offered ============================ o Are Not FDIC Insured o May Lose Value o Are Not Bank Guaranteed ============================ AllianceBernstein Investment Research and Management, Inc., the principal underwriter of the AllianceBernstein mutual funds and an affiliate of Alliance Capital Management L.P., the manager of the funds, is a member of the NASD. June 9, 2003 Semi-Annual Report This report provides management's discussion of fund performance for Alliance National Municipal Income Fund's (the "Fund") semi-annual reporting period ended April 30, 2003. Investment Objective and Policies The Fund is a closed-end management investment company designed for investors who seek high current income exempt from regular federal income tax. The Fund normally invests at least 75% of its assets in investment grade municipal securities. Investment Results The following table provides performance data for the Fund and its benchmark, the Lehman Brothers Municipal Bond Index, for the six- and 12-month periods ended April 30, 2003. For comparison, returns for the Lipper General & Leveraged Municipal Debt Funds Average are also included. INVESTMENT RESULTS* Periods Ended April 30, 2003 =========================== Returns =========================== 6 Months 12 Months -------------------------------------------------------------------------------- Alliance National Municipal Income Fund (NAV) 5.67% 14.22% -------------------------------------------------------------------------------- Lehman Brothers Municipal Bond Index 3.59% 8.49% -------------------------------------------------------------------------------- Lipper General & Leveraged Municipal Debt Funds Average 5.24% 10.27% -------------------------------------------------------------------------------- *The Fund's investment results are for the periods shown and are based on the Fund's net asset value (NAV) as of April 30, 2003. All fees and expenses related to the operation of the Fund have been deducted. Returns for the Fund include the reinvestment of any distributions paid during the period. Past performance is no guarantee of future results. The Lehman Brothers Municipal Bond Index is a total return performance benchmark for the long-term, investment grade tax-exempt bond market. The Lipper General & Leveraged Municipal Debt Funds Average is comprised of leveraged closed-end funds with generally similar investment objectives to Alliance National Municipal Income Fund. An investor cannot invest directly in an index, and its results are not indicative of any specific investment, including Alliance National Municipal Income Fund. Investment Results For the past six months ended April 30, 2003, the municipal bond market posted positive returns. The Fund generated a positive return as well, outperforming its benchmark, the Lehman Brothers Municipal Bond Index, as well as the Lipper General & Leverage Municipal Debt Funds Average. The Fund's outperformance in comparison to its Lipper peer group can be attributed to its relatively high average credit quality. Over the past 12 months, municipal bond yields declined substantially. This resulted in strong positive price performance for the municipal bond market. The Fund also generated a positive rate of return over this period. For the 12 months, the Fund outperformed both -------------------------------------------------------------------------------- ALLIANCE NATIONAL MUNICIPAL INCOME FUND o 1 the Lehman Brothers Municipal Bond Index and the Lipper General & Leveraged Municipal Debt Funds Average. Once again, the Fund's relatively strong performance is attributable to the Fund's higher average credit quality. In addition, the Fund's performance was aided by the advance refunding of a 2.5% position, Alabama's Jefferson County Sewer Revenue. An advance refunding results in the bond becoming secured by U.S. government securities, and its effective maturity date becomes the same as the first call date. These two modifications result in a substantial increase in bond price. Market Review and Investment Strategy The pace of municipal issuance continues to be quite strong. Year-to-date issuance has totaled $145.6 billion--an increase of almost 14% from the same period in 2002. This high level of issuance has impaired municipal price performance relative to the taxable bond market. State and local governments are currently mired in their worst financial crises in decades. Policy makers are debating how much to cut expenses and raise taxes to close their projected budget shortfalls. The Center on Budget and Policy Priorities estimates that states' collective projected budget deficits could reach $85 billion in fiscal year 2004. Two states, California and Oregon, were recently downgraded by Moody's Investors Service, and 16 more continue to have "negative" outlooks, meaning they are at risk for being downgraded, as well. The Fund has minimal general obligation exposure and, therefore, has generally been sheltered from the recent credit spread widening affecting these bonds. Investment activity over the past six months focused on improving the credit quality of the Fund. The Fund's exposure to the health care and tobacco settlement sectors was reduced over the period and replaced by higher credit quality bonds. In an effort to maintain a low cost of leverage, one series of its variable rate preferred stock was reset into an extended rate mode expiring in December, 2003. Two other series had been previously reset into extended rate mode, expiring in August, 2003. The final series continues to reset on a weekly basis. -------------------------------------------------------------------------------- 2 o ALLIANCE NATIONAL MUNICIPAL INCOME FUND PORTFOLIO OF INVESTMENTS April 30, 2003 (unaudited) Standard Principal & Poor's Amount Rating (000) Value -------------------------------------------------------------------------------- MUNICIPAL BONDS-162.2% Long-Term Municipal Bonds-160.8% Alabama-9.1% Huntsville Hlth Care Auth (Huntsville Hosp Sys) Ser 02B 5.75%, 6/01/32(a)..................

(the "Fund"), was incorporated in the state of Maryland on November 9, 2001 and is registered under the Investment Company Act of 1940 as a non-diversified, closed-end management investment company. Prior to the commencement of operations on January 28, 2002, the Fund had no operations other than the sale to Alliance Capital Management L.P. (the "Adviser") of 6,667 shares in the amount of $100,005 on January 23, 2002. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States, which require management to make certain estimates and assumptions that affect the reporting amounts of assets and liabilities in the financial statements and amounts of income and expenses during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund. 1. Security Valuation In accordance with Pricing Policies adopted by the Board of Directors of the Fund (the "Pricing Policies") and applicable law, portfolio securities are valued at current market value or at fair value. The Board of Directors has delegated to the Adviser, subject to the Board's continuing oversight, certain responsibilities with respect to the implementation of the Pricing Policies. Pursuant to the Pricing Policies, securities for which market quotations are readily available are valued at their current market value. In general, the market value of these securities is determined as follows: Securities listed on a national securities exchange or on a foreign securities exchange are valued at the last sale price at the close of the exchange or foreign securities exchange. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices on such day. If no bid or asked prices are quoted on such day, then the security is valued in good faith at fair value in accordance with the Pricing Policies. Securities listed on more than one exchange are valued by reference to the principal exchange on which the securities are traded; securities not listed on an exchange but traded on The Nasdaq Stock Market, Inc. ("NASDAQ") are valued in accordance with the NASDAQ Official Closing Price; listed put or call options are valued at the last sale price. If there has been no sale on that day, such securities will be valued at the closing bid prices on that day; open futures contracts and options thereon are valued using the closing settlement price or, in the absence of such a price, the most recent quoted bid price. If there are no quotations available for the day of valuations, the last available closing settlement price is used; securities traded in the over-the-counter market, (but excluding securities traded on NASDAQ) are valued at the mean of the current bid and asked prices as reported by the National Quotation Bureau or other comparable sources; U.S. Government securities and other debt instruments having 60 days or less remaining until maturity are valued at amor- -------------------------------------------------------------------------------- ALLIANCE NATIONAL MUNICIPAL INCOME FUND o 15 tized cost if their original maturity was 60 days or less, or by amortizing their fair value as of the 61st day prior to maturity if their original term to maturity exceeded 60 days; fixed-income securities, including mortgage backed and asset backed securities, may be valued on the basis of prices provided by a pricing service or at a price obtained from one or more of the major broker/dealers. In cases where broker/dealer quotes are obtained, the Pricing Policies provide that the Adviser may establish procedures whereby changes in market yields or spreads are used to adjust, on a daily basis, a recently obtained quoted price on a security; and OTC and other derivatives are valued on the basis of a quoted bid price or spread from a major broker/dealer in such security. Securities for which market quotations are not readily available are valued at fair value in accordance with the Pricing Policies. 2. Taxes It is the Fund's policy to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income and net realized gains, if any, to shareholders. Therefore, no provisions for federal income or excise taxes are required. 3. Investment Income and Investment Transactions Interest income is accrued daily. Investment transactions are accounted for on the date the securities are purchased or sold. Investment gains and losses are determined on the identified cost basis. The Fund amortizes premiums and accretes original issue discounts and market discounts as adjustments to interest income. 4. Dividends and Distributions Dividends and distributions to shareholders are recorded on the ex-dividend date. Income and capital gains distributions are determined in accordance with federal tax regulations and may differ from those determined in accordance with accounting principles generally accepted in the United States. To the extent these differences are permanent, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require such reclassification. NOTE B Advisory Fee and Other Transactions with Affiliates Under the terms of an investment advisory agreement, the Fund pays the Adviser an advisory fee at an annual rate of .65 of 1% of the Fund's average daily net assets. Such fee is accrued daily and paid monthly. The Adviser has agreed to waive a portion of its fees or reimburse the Fund for expenses in the amount of 0.25% of the Fund's average daily net assets for the first 5 full years of the Fund's operations, 0.20% of the Fund's average daily net assets in year 6, 0.15% in year 7, 0.10% in year 8, and 0.05% in year 9. For the period ended April 30, 2003, the amount of such fees waived was $621,969. -------------------------------------------------------------------------------- 16 o ALLIANCE NATIONAL MUNICIPAL INCOME FUND Under the term of a Shareholder, Inquiry Agency Agreement with Alliance Global Investor Services, Inc. (AGIS), an affiliate of the Adviser, the Fund reimburses AGIS for costs relating to servicing phone inquiries for the Fund.During the period ended April 30, 2003, there was no reimbursement paid to AGIS. NOTE C Investment Transactions Purchases and sales of investment securities (excluding short-term investments) for the period ended April 30, 2003, were as follows: Purchases Sales --------------- --------------- Investment securities................... $ 31,253,599 $ 27,837,910 U.S. government securities.............. -0- -0- At April 30, 2003, the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes.

(1,842,579) ------------- Net unrealized appreciation............................ $ 21,678,549 ------------- NOTE D Distributions To Common Shareholders The tax character of distributions to be paid for the year ending October 30, 2003 will be determined at the end of the current fiscal year.

(1,199,398)(b) Unrealized appreciation/(depreciation)................. 13,765,340 ------------- Total accumulated earnings/(deficit)................... $ 14,631,847 ------------- (a) Total distributions paid differ from the statement of changes in net assets applicable to common shareholders because for tax purposes dividends are recognized when actually paid. (b) On October 31, 2002, the Fund had a net capital loss carryforward of $ 1,199,398, all of which expires in the year 2010. To the extent future capital gains are offset by capital loss carryforward, such gains will not be distributed.

Also, the Fund issued an additional 1,565,000 shares in connection with the exercise by the underwriters of the over-allotment option. NOTE F Preferred Stock The Fund has authorized, issued and outstanding 7,800 shares of Auction Preferred Stock, consisting of 1,950 shares each of Series M, Series T, Series W and Series TH.

Conversely, total investment return based on net asset value will be lower than total investment return based on market value in periods where there is a decrease in the discount or an increase in the premium of the market value to the net asset value from the beginning to the end of the period. Total investment return calculated for a period of less than one year is not annualized. (e) Annualized. (f) These expense and net investment income ratios do not reflect the effect of dividend payments to preferred shareholders. -------------------------------------------------------------------------------- ALLIANCE NATIONAL MUNICIPAL INCOME FUND o 21 ADDITIONALINFORMATION (unaudited) Supplemental Proxy Information The Annual Meeting of Shareholders of Alliance National Municipal Income Fund, Inc. was held on March 20, 2003.
