December 14, 2004 Annual Report This report provides management's discussion of fund performance for ACM Municipal Securities Income Fund (the "Fund"), a closed-end fund that trades under the New York Stock Exchange symbol "AMU", for the annual reporting period ended October 31, 2004. Investment Objective and Policies The Fund is a closed-end management investment company designed to provide high current income exempt from regular federal income tax. The Fund invests substantially all of its assets in investment grade municipal securities. For more information regarding the Fund's risks, please see "A Word About Risk" on page 3 and "Note G--Risks Involved in Investing in the Fund" of the Notes to Financial Statements on page 21. Investment Results The table on page 4 provides performance data for the Fund and its benchmark, the Lehman Brothers (LB) Municipal Index, for the six- and 12-month periods ended October 31, 2004. For comparison, returns for the Lipper General Municipal Debt Funds (Leveraged) Average (the "Lipper Average") are also included. The funds that comprise the Lipper Average have generally similar investment objectives to the Fund, although some may have different investment policies and sales and management fees. The Fund outperformed its benchmark during both the six- and 12-month reporting periods ended October 31, 2004. The Fund's stronger relative performance during the 12-month period was largely the result of security selection in the general obligation, insured and tobacco settlement sectors. The Fund's relative exposure to the pre-refunded, industrial revenue bond and hospital sectors also contributed positively to the Fund's performance. In addition, the Fund's leveraged structure benefited its performance, primarily because of historically low borrowing costs. During the 12-month reporting period, the Fund also outperformed its peer group, as represented by the Lipper Average. Market Review and Investment Strategy From October 31, 2003 to October 31, 2004, yields for long-term muni-cipal bonds declined and yields for short-term municipal bonds rose. For example, yields for bonds maturing in 20 years declined by 0.37%; yields for 5-year bonds rose 0.21%. Institutional investors generated strong demand for bonds maturing in 20 years. Short maturity bond yields generally rose as investors anticipated a stronger economy and likely tighter monetary policy by the U.S. Federal Reserve. Over that time period, the long municipal bond market outperformed the taxable bond market. For example, the LB Municipal Index gained 6.03% during the 12-month reporting period ended October 31, 2004 while the LB U.S. Aggregate Index, representing taxable bonds, generated a return of 5.53% over the same period. The Treasury bond component of the LB U.S. Aggregate Index posted an even lower return of 4.97%. As of October 31, 2004, 30-year municipal bonds were yielding approximately 96% of comparable maturity Treasury bonds. - ------------------------------------------------------------------------------- ACM MUNICIPAL SECURITIES INCOME FUND o 1 The low rate environment has resulted in continued strong demand for lower-rated bonds that carry higher yields. Bonds in sectors with generally lower credit profiles again led the market in performance; the industrial development and hospital sub-sectors of the LB Municipal Index, for example, generated returns of 10.47% and 8.52%, respectively. Several states, notably California, showed improved credit fundamentals compared to the beginning of 2004 and, as a result, their bonds outperformed the general market. During the annual reporting period, the Fund's portfolio management team employed a number of investment strategies which included reducing the Fund's exposure to 30-year 5.0% coupon bonds and replacing the longer maturity bonds with 20- to 25-year 5.0%-5.25% coupon bonds. The team also increased the term structure diversification of the Fund's investment portfolio. In addition, the team focused on buying premium coupon callable bonds versus discount coupon bonds and non-callable bonds, and capitalized on the market's strong demand for yield by selling lower-rated bonds. In Memory It is with sadness that we announce the passing of Clifford L. Michel, a member of the Board of Directors of ACM Municipal Securities Income Fund. Mr. Michel served the interests of the Fund's shareholders for the last 11 years. His hard work, dedication and contributions to the Fund will be greatly missed. _______________________________________________________________________________ 2 o ACM MUNICIPAL SECURITIES INCOME FUND Historical Performance - ------------------------------------------------------------------------------- HISTORICAL PERFORMANCE An Important Note About the Value of Historical Performance The performance on the following page represents past performance and does not guarantee future results. Current performance may be lower or higher than the performance information shown. Returns are annualized for periods longer than one year.

ACM Municipal Securities Income Fund Shareholder Information Daily market prices for the Fund's shares are published in the New York Stock Exchange Composite Transaction section of The Wall Street Journal under the abbreviation "ACM MuniSec." The Fund's NYSE trading symbol is "AMU." Weekly comparative net asset value (NAV) and market price information about the Fund is published each Monday in The Wall Street Journal, each Sunday in The New York Times and each Saturday in Barron's and other newspapers in a table called "Closed-End Bond Funds." For additional shareholder information regarding this Fund, please see page 35. Benchmark Disclosure The unmanaged Lehman Brothers (LB) Municipal Index does not reflect fees and expenses associated with the active management of a mutual fund portfolio. The Index is a total return performance benchmark for the long-term, investment grade, tax-exempt bond market. For the six- and 12-month periods ended October 31, 2004, the Lipper General Municipal Debt Funds (Leveraged) Average consisted of 66 and 65 funds, respectively. These funds have generally similar investment objectives to the Fund, although some may have different investment policies and sales and management fees. An investor cannot invest directly in an index or average, and their results are not indicative of the performance for any specific investment, including the Fund. A Word About Risk Among the risks of investing in the Fund are changes in the general level of interest rates or bond credit quality ratings. Changes in interest rates have a greater effect on bonds with longer maturities than on those with shorter maturities. While the Fund invests principally in bonds and other fixed-income securities, in order to achieve its investment objectives, the Fund may at times use certain types of investment derivatives, such as options, futures, forwards and swaps. These instruments involve risks different from, and in certain cases, greater than, the risks presented by more traditional investments. At the discretion of the Fund's Adviser, the Fund may invest up to 20% of its total assets in securities that are not rated and up to 10% in securities that are not readily marketable. The issuance of the Fund's preferred stock results in leveraging of the Common Stock, an investment technique usually considered speculative. Leverage creates certain risks for holders of Common Stock, including higher volatility of both the net asset value and market value of the Common Stock, and fluctuations in the dividend rates on the preferred stock will affect the return to holders of Common Stock. If the Fund were fully invested in longer-term securities and if short-term interest rates were to increase, then the amount of dividends paid on the preferred shares would increase and both net investment income available for distribution to the holders of Common Stock and the net asset value of the Common Stock would decline. At the same time, the market value of the Fund's Common Stock (that is, its price as listed on the New York Stock Exchange) may, as a result, decline. Furthermore, if long-term interest rates rise, the Common Stock's net asset value will reflect the full decline in the price of the portfolio's investments, since the value of the Fund's Preferred Stock does not fluctuate. In addition to the decline in net asset value, the market value of the Fund's Common Stock may also decline.

(the "Fund"), was incorporated in the state of Maryland on February 11, 1993 and is registered under the Investment Company Act of 1940 as a diversified, closed-end management investment company. The financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported 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 Portfolio securities are valued at their current market value determined on the basis of market quotations or, if market quotations are not readily available or are deemed unreliable, at "fair value" as determined in accordance with procedures established by and under the general supervision of the Fund's Board of Directors. In general, the market value of securities which are readily available and deemed reliable are 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. 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 valuation, the last available closing settlement price is used; securities traded in the over-the-counter market, (OTC) (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 amortized 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, Alliance Capital Management, L.P. (the "Adviser") may _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 17 Notes to Financial Statements - ------------------------------------------------------------------------------- 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 (including restricted securities) or are deemed unreliable are valued at fair value. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, analysis of the issuer's financial statements or other available documents. In addition, the Fund may use fair value pricing for securities primarily traded in non-U.S. markets because, most foreign markets close well before the Fund values its securities at 4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim and may materially affect the value of those securities. 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 substantially 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 trade date 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 U.S. generally accepted accounting principles. 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, Administrative Fees 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 .50 of 1% of the average weekly net assets of the Fund. Such fee is accrued daily and paid monthly. Under the terms of a Shareholder Inquiry Agency Agreement with Alliance Global Investor Services, Inc. (AGIS), an affiliate of the Adviser, the Fund reim- _______________________________________________________________________________ 18 o ACM MUNICIPAL SECURITIES INCOME FUND Notes to Financial Statements - ------------------------------------------------------------------------------- burses AGIS for costs relating to servicing phone inquiries for the Fund. During the year ended October 31, 2004, there was no reimbursement paid to AGIS. Under the terms of an Administration Agreement, the Fund pays Alliance Capital Management L.P. (the "Administrator") an administration fee at an annual rate of .15 of 1% of the average weekly net assets of the Fund. Such fee is accrued daily and paid monthly. The Administrator has engaged Prudential Investments LLC (the "Sub-Administrator"), an indirect, wholly-owned subsidiary of Prudential Financial, Inc., to act as sub-administrator. The Administrator, out of its own assets, will pay the Sub-Administrator a monthly fee equal to an annual rate of .10 of 1% of the Fund's average weekly net assets. The Sub-Administrator prepares financial and regulatory reports for the Fund and provides other clerical services. NOTE C Investment Transactions Purchases and sales of investment securities (excluding short-term investments) for the year ended October 31, 2004, were as follows: Purchases Sales ============= ============= Investment securities (excluding U.S. government securities) $ 75,792,898 $ 74,400,753 U.S. government securities -0- -0- The cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes. Accordingly, gross unrealized appreciation and unrealized depreciation (excluding swaps) are as follows: Gross unrealized appreciation $ 10,307,605 Gross unrealized depreciation (1,202,180) ------------- Net unrealized appreciation $ 9,105,425 ============= Swap Agreements The Fund may enter into swaps to hedge its exposure to interest rates and credit risk and for investment purposes. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specific amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of the counterparty is generally limited to the net interest payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 19 Notes to Financial Statements - ------------------------------------------------------------------------------- As of November 1, 2003, the Fund has adopted the method of accounting for interim payments on swap contracts in accordance with Financial Accounting Standards Board Statement No. 133. The Fund accrues for the interim payments on swap contracts on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swap contracts on the statement of assets and liabilities. Once the interim payments are settled in cash, the net amount is recorded as realized gain/loss on swaps, in addition to realized gain/loss recorded upon the termination of swap contracts on the statement of operations. Prior to November 1, 2003, these interim payments were reflected within interest income/expense in the statement of operations. Fluctuations in the value of swap contracts are recorded as a component of net change in unrealized appreciation/depreciation of investments. NOTE D Distributions To Common Shareholders The tax character of distributions to be paid for the year ending October 31, 2004 will be determined at the end of the current fiscal year. The tax character of distributions paid to common shareholders during the fiscal years ended October 31, 2004 and October 31, 2003 were as follows: 2004 2003 ============= ============= Distributions paid from: Ordinary income $ 65,384 $ 87,103 Tax-exempt income 9,595,248 8,715,232 ------------- ------------- Total distributions paid $ 9,660,632 $ 8,802,335 ============= ============= As of October 31, 2004, the components of accumulated earnings/(deficit) applicable to common shareholders on a tax basis were as follows: Undistributed net tax exempt income $ 162,944 Accumulated capital and other losses (23,465,455)(a) Unrealized appreciation/(depreciation) 9,127,197(b) ------------- Total accumulated earnings/(deficit) $ (14,175,314)(c) ============= (a) On October 31, 2004, the Fund had a net capital loss carryforward of $23,465,455 of which $6,110,148 expires in the year 2007, $10,294,946 expires in the year 2008, $1,971,343 expires in the year 2010, and $5,089,018 expires in the year 2011. To the extent future capital gains are offset by capital loss carryforward, such gains will not be distributed. During the current fiscal year capital loss carryforward of $365,370 was utilized. (b) The difference between book-basis and tax-basis unrealized appreciation/(depreciation) is attributable primarily to the tax deferral of losses on wash sales and the difference between the book and tax treatment of swap income. (c) The difference between book-basis and tax-basis components of accumulated earnings/(deficits) is attributable primarily to dividends payable. During the current fiscal year, permanent differences, primarily due to the tax treatment of swap income, resulted in a net decrease of undistributed net investment income, and a decrease in accumulated net realized loss on investment transactions. This reclassification had no effect on net assets. _______________________________________________________________________________ 20 o ACM MUNICIPAL SECURITIES INCOME FUND Notes to Financial Statements - ------------------------------------------------------------------------------- NOTE E Common Stock There are 99,996,400 shares of $0.01 par value common stock authorized. There are 11,140,470 shares of common stock outstanding at October 31, 2004. During the year ended October 31, 2004 and the year ended October 31, 2003, the Fund issued 65,850 and 73,818 shares, respectively, in connection with the Fund's dividend reinvestment plan. NOTE F Preferred Stock The Fund has issued and outstanding 3,600 shares of Auction Preferred Stock, consisting of 1,200 shares each of Series A, Series B and Series C. The preferred shares have a liquidation value of $25,000 per share plus accumulated, unpaid dividends. The dividend rate on Series A is 1.323%, effective through March 9, 2005. The dividend rate on Series B is 1.55%, effective through November 1, 2004. The dividend rate on Series C is 1.51%, effective through November 4, 2004. At certain times, the Preferred Shares are redeemable by the Fund, in whole or in part, at $25,000 per share plus accumulated, unpaid dividends. Although the Fund will not ordinarily redeem the Preferred Shares, it may be required to redeem shares if, for example, the Fund does not meet an asset coverage ratio required by law or to correct a failure to meet a rating agency guideline in a timely manner. The Fund voluntarily may redeem the Preferred Shares in certain circumstances. The Preferred Shareholders, voting as a separate class, have the right to elect at least two Directors at all times and to elect a majority of the Directors in the event two years' dividends on the Preferred Shares are unpaid. In each case, the remaining Directors will be elected by the Common Shareholders and Preferred Shareholders voting together as a single class. The Preferred Shareholders will vote as a separate class on certain other matters as required under the Fund's Charter, the Investment Company Act of 1940 and Maryland law. NOTE G Risks Involved in Investing in the Fund Interest Rate Risk and Credit Risk--Interest rate risk is the risk that changes in interest rates will affect the value of the Fund's investments in fixed-income debt securities such as bonds or notes. Increases in interest rates may cause the value of the Fund's investments to decline. Credit risk is the risk that the issuer or guarantor of a debt security, or the counterparty to a derivative contract, will be unable or unwilling to make timely principal and/or interest payments, or to _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 21 Notes to Financial Statements - ------------------------------------------------------------------------------- otherwise honor its obligations. The degree of risk for a particular security may be reflected in its credit risk rating. Credit risk is greater for medium quality and lower-rated securities. Lower-rated debt securities and similar unrated securities (commonly known as "junk bonds") have speculative elements or are predominantly speculative risks. Indemnification Risk--In the ordinary course of business, the Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these indemnification provisions and expects the risk of loss thereunder to be remote. NOTE H Legal Proceedings As has been previously reported, the staff of the U.S. Securities and Exchange Commission ("SEC") and the Office of the New York Attorney General ("NYAG") have been investigating practices in the mutual fund industry identified as "market timing" and "late trading" of mutual fund shares. Certain other regulatory authorities have also been conducting investigations into these practices within the industry and have requested that the Adviser provide information to them. The Adviser has been cooperating and will continue to cooperate with all of these authorities. The shares of the Fund are not redeemable by the Fund, but are traded on an exchange at prices established by the market. Accordingly, the Fund and its shareholders are not subject to the market timing and late trading practices that are the subject of the investigations mentioned above or the lawsuits described below. Please see below for a description of the agreements reached by the Adviser and the SEC and NYAG in connection with the investigations mentioned above. Numerous lawsuits have been filed against the Adviser and certain other defendants in which plaintiffs make claims purportedly based on or related to the same practices that are the subject of the SEC and NYAG investigations referred to above. Some of these lawsuits name the Fund as a party. The lawsuits are now pending in the United States District Court for the District of Maryland pursuant to a ruling by the Judicial Panel on Multidistrict Litigation transferring and centralizing all of the mutual funds involving market and late trading in the District of Maryland. Management of the Adviser believes that these private lawsuits are not likely to have a material adverse effect on the results of operations or financial condition of the Fund. On December 18, 2003, the Adviser confirmed that it had reached terms with the SEC and the NYAG for the resolution of regulatory claims relating to the practice of "market timing" mutual fund shares in some of the AllianceBernstein Mutual Funds. The agreement with the SEC is reflected in an Order of the Commission ("SEC Order"). The agreement with the NYAG is memorialized in _______________________________________________________________________________ 22 o ACM MUNICIPAL SECURITIES INCOME FUND Notes to Financial Statements - ------------------------------------------------------------------------------- an Assurance of Discontinuance dated September 1, 2004 ("NYAG Order"). Among the key provisions of these agreements are the following: (i) The Adviser agreed to establish a $250 million fund (the "Reimbursement Fund") to compensate mutual fund shareholders for the adverse effects of market timing attributable to market timing relationships described in the SEC Order. According to the SEC Order, the Reimbursement Fund is to be paid, in order of priority, to fund investors based on (i) their aliquot share of losses suffered by the fund due to market timing, and (ii) a proportionate share of advisory fees paid by such fund during the period of such market timing; (ii) The Adviser agreed to reduce the advisory fees it receives from some of the AllianceBernstein long-term, open-end retail funds, commencing January 1, 2004, for a period of at least five years; and (iii) The Adviser agreed to implement changes to its governance and compliance procedures. Additionally, the SEC Order contemplates that the Adviser's registered investment company clients, including the Fund, will introduce governance and compliance changes. The shares of the Fund are not redeemable by the Fund, but are traded on an exchange at prices established by the market. Accordingly, the Fund and its shareholders are not subject to the market timing practices described in the SEC Order and are not expected to participate in the Reimbursement Fund. Since the Fund is a closed-end fund, it will not have its advisory fee reduced pursuant to the terms of the agreements mentioned above. The Adviser and approximately twelve other investment management firms were publicly mentioned in connection with the settlement by the SEC of charges that an unaffiliated broker/dealer violated federal securities laws relating to its receipt of compensation for selling specific mutual funds and the disclosure of such compensation. The SEC has indicated publicly that, among other things, it is considering enforcement action in connection with mutual funds' disclosure of such arrangements and in connection with the practice of considering mutual fund sales in the direction of brokerage commissions from fund portfolio transactions. The SEC has issued subpoenas to the Adviser in connection with this matter and the Adviser has provided documents and other information to the SEC and is cooperating fully with its investigation. On June 22, 2004, a purported class action complaint entitled Aucoin, et al. v. Alliance Capital Management L.P., et al. ("Aucoin Complaint") was filed against the Adviser, Alliance Capital Management Holding L.P., Alliance Capital Management Corporation, AXA Financial, Inc., AllianceBernstein Investment Research & Management, Inc., certain current and former directors of the _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 23 Notes to Financial Statements - ------------------------------------------------------------------------------- AllianceBernstein Mutual Funds, and unnamed Doe defendants. The Aucoin Complaint names certain of the AllianceBernstein mutual funds as nominal defendants. The Aucoin Complaint was filed in the United States District Court for the Southern District of New York by an alleged shareholder of an AllianceBernstein mutual fund. The Aucoin Complaint alleges, among other things, (i) that certain of the defendants improperly authorized the payment of excessive commissions and other fees from fund assets to broker-dealers in exchange for preferential marketing services, (ii) that certain of the defendants misrepresented and omitted from registration statements and other reports material facts concerning such payments, and (iii) that certain defendants caused such conduct as control persons of other defendants. The Aucoin Complaint asserts claims for violation of Sections 34(b), 36(b) and 48(a) of the Investment Company Act, Sections 206 and 215 of the Advisers Act, breach of common law fiduciary duties, and aiding and abetting breaches of common law fiduciary duties. Plaintiffs seek an unspecified amount of compensatory damages and punitive damages, rescission of their contracts with the Adviser, including recovery of all fees paid to the Adviser pursuant to such contracts, an accounting of all fund-related fees, commissions and soft dollar payments, and restitution of all unlawfully or discriminatorily obtained fees and expenses. Since June 22, 2004, numerous additional lawsuits making factual allegations substantially similar to those in the Aucoin Complaint were filed against the Adviser and certain other defendants, and others may be filed. The Adviser believes that these matters are not likely to have a material adverse effect on the Fund or the Adviser's ability to perform advisory services relating to the Fund. _______________________________________________________________________________ 24 o ACM MUNICIPAL SECURITIES INCOME FUND Financial Highlights - ------------------------------------------------------------------------------- FINANCIAL HIGHLIGHTS Selected Data For A Share Of Capital Stock Outstanding Throughout Each Period Year Ended October 31, --------------------------------------------------------------- 2004(a) 2003 2002 2001 2000 ----------- ----------- ----------- ----------- ----------- Net asset value, beginning of period $11.05 $10.85 $12.10 $11.71 $11.64 INCOME FROM INVESTMENT OPERATIONS Net investment income .88 .97 1.08 1.15 1.12 Net realized and unrealized gain (loss) on investment transactions .41 .12 (1.32) .45 .16 Dividends to preferred shareholders from net investment income (common stock equivalent basis) (.09) (.09) (.14) (.27) (.34) Net increase (decrease) in net asset value from operations 1.20 1.00 (.38) 1.33 .94 LESS: DIVIDENDS AND DISTRIBUTIONS TO COMMON SHAREHOLDERS Dividends from net investment income (.87) (.80) (.87) (.88) (.78) Distributions in excess of net investment income -0- -0- -0- (.06) (.09) Total dividends and distributions to common shareholders (.87) (.80) (.87) (.94) (.87) Net asset value, end of period $11.38 $11.05 $10.85 $12.10 $11.71 Market price, end of period $12.09 $11.62 $11.50 $12.70 $12.56 Premium 6.24% 5.16% 5.99% 4.96% 7.26% TOTAL RETURN Total investment return based on:(b) Market price 12.34% 8.53% (2.44)% 9.14% 16.16% Net asset value 11.20% 9.39% (3.35)% 11.59% 8.74% RATIOS/SUPPLEMENTAL DATA Net assets, applicable to common shareholders, end of period (000's omitted) $126,739 $122,322 $119,323 $132,201 $127,142 Preferred stock, at redemption value ($25,000 per share liquidation preference) (000's omitted) $90,000 $90,000 $90,000 $90,000 $90,000 Ratios to average net assets applicable to common shareholders of: Expenses(c) 1.65% 1.71% 1.65% 1.53% 1.61% Net investment income, before preferred stock dividends(c) 7.87% 8.78% 9.32% 9.60% 9.92% Preferred stock dividends .79% .84% 1.19% 2.26% 3.03% Net investment income, net of preferred stock dividends 7.08% 7.94% 8.13% 7.34% 6.89% Portfolio turnover rate 36% 32% 24% 82% 360% Asset coverage ratio 241% 236% 233% 247% 241% See footnote summary on page 26. _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 25 Financial Highlights - ------------------------------------------------------------------------------- (a) As of November 1, 2003, the Fund has adopted the method of accounting for interim payments on swap contracts in accordance with Financial Accounting Standards Board Statement No. 133. These interim payments are reflected within net realized and unrealized gain (loss) on swap contracts, however, prior to November 1, 2003, these interim payments were reflected within interest income/expense on the statement of operations. For the year ended October 31, 2004, the effect of this change to the net investment income and the net realized and unrealized gain (loss) on investment transactions was less than $0.01 per share and the ratio of net investment income to average net assets was less than .01%. (b) Total investment return is calculated assuming a purchase of common stock on the opening of the first day and a sale on the closing of the last day of each period reported. Dividends and distributions, if any, are assumed for purposes of this calculation, to be reinvested at prices obtained under the Fund's dividend reinvestment plan. Generally, total investment return based on net asset value will be higher than total investment return based on market value in periods where there is an increase in the discount or a decrease in the premium of the market value to net asset value from the beginning to the end of such periods. 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. (c) These expense and net investment income ratios do not reflect the effect of dividend payments to preferred shareholders. _______________________________________________________________________________ 26 o ACM MUNICIPAL SECURITIES INCOME FUND Report of Independent Registered Public Accounting Firm - ------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Directors of ACM Municipal Securities Income Fund, Inc. We have audited the accompanying statement of assets and liabilities of ACM Municipal Securities Income Fund, Inc., (the "Fund") including the portfolio of investments, as of October 31, 2004, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned as of October 31, 2004, by correspondence with the custodian and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of ACM Municipal Securities Income Fund, Inc. at October 31, 2004, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP New York, New York December 15, 2004 FEDERAL TAX INFORMATION (unaudited) In accordance with Federal tax law, the Fund's designation of "exempt-interest dividends" paid during the fiscal year ended October 31, 2004 was $10,569,502. As required by Federal tax law rules, shareholders will receive notification of their portion of the Fund's taxable ordinary dividends (if any) and capital gain distributions (if any) paid for the 2004 calendar year on Form 1099-DIV which will be mailed by January 31, 2005. _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 27 Additional Information - ------------------------------------------------------------------------------- ADDITIONAL INFORMATION (unaudited) Shareholders whose shares are registered in their own names will automatically be participants in the Dividend Reinvestment and Cash Purchase Plan (the "Plan"), pursuant to which dividends and capital gain distributions to shareholders will be paid in or reinvested in additional shares of the Fund (the "Dividend Shares"). Equiserve Trust Company N.A. (the "Agent") will act as agent for participants under the Plan. Shareholders whose shares are held in the name of broker or nominee should contact such broker or nominee to determine whether or how they may participate in the Plan. If the Board declares an income distribution or determines to make a capital gain distribution payable either in shares or in cash, as holders of the Common Stock may have elected, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in shares of Common Stock of the Fund valued as follows: (i) If the shares of Common Stock are trading at net asset value or at a premium above net asset value at the time of valuation, the Fund will issue new shares at the greater of net asset value or 95% of the then current market price. (ii) If the shares of Common Stock are trading at a discount from net asset value at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and apply it to the purchase of the Fund's shares of Common Stock in the open market on the New York Stock Exchange or elsewhere, for the participants' accounts. Such purchases will be made on or shortly after the payment date for such dividend or distribution and in no event more than 30 days after such date except where temporary curtailment or suspension of purchase is necessary to comply with Federal securities laws. If, before the Plan agent has completed its purchases, the market price exceeds the net asset value of a share of Common Stock, the average purchase price per share paid by the Plan agent may exceed the net asset value of the Fund's shares of Common Stock, resulting in the acquisition of fewer shares than if the dividend or distribution had been paid in shares issued by the Fund. The Agent will maintain all shareholders' accounts in the Plan and furnish written confirmation of all transactions in the account, including information needed by shareholders for tax records. Shares in the account of each Plan participant will be held by the Agent in non-certificate form in the name of the participant, and each shareholder's proxy will include those shares purchased or received pursuant to the Plan. There will be no charges with respect to shares issued directly by the Fund to satisfy the dividend reinvestment requirements. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Agent's open market purchases of shares. In each case, the cost per share of shares purchased for each shareholder's account will be the average _______________________________________________________________________________ 28 o ACM MUNICIPAL SECURITIES INCOME FUND Additional Information - ------------------------------------------------------------------------------- cost, including brokerage commissions, of any shares purchased in the open market plus the cost of any shares issued by the Fund. The automatic reinvestment of dividends and distributions will not relieve participants of any income taxes that may be payable (or required to be withheld) on dividends and distributions. Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan as applied to any voluntary cash payments made and any dividend or distribution paid subsequent to written notice of the change sent to participants in the Plan at least 90 days before the record date for such dividend or distribution. The Plan may also be amended or terminated by the Agent on at least 90 days' written notice to participants in the Plan. All correspondence concerning the Plan should be directed to the Agent at Equiserve Trust Company N.A., P.O. Box 43011, Providence, RI 02940-3011. Since the filing of the most recent amendment to the Fund's registration statement with the Securities and Exchange Commission, there have been (i) no material changes in the Fund's investment objectives or policies, (ii) no changes to the Fund's charter or by-laws that would delay or prevent a change of control of the Fund, and (iii) no material changes in the principal risk factors associated with investment in the Fund, and (iv) no change to the persons primarily responsible for the day-to-day management of the Fund's investment port-folio, who are David Dowden and Terrance Hults, each of whom is a Vice President of the Fund. _______________________________________________________________________________ ACM MUNICIPAL SECURITIES INCOME FUND o 29 Board of Directors - ------------------------------------------------------------------------------- BOARD OF DIRECTORS William H.

Please see Schedule of Investments contained in the Report to Shareholders included under Item 1 of this Form N-CSR. ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. The registrant has adopted the following proxy voting policies and procedures of its investment adviser, Alliance Capital Management L.P. October 2004 ALLIANCE CAPITAL MANAGEMENT L.P. Statement of Policies and Procedures for Proxy Voting Introduction As a registered investment adviser, Alliance Capital Management L.P. ("Alliance Capital", "we" or "us") has a fiduciary duty to act solely in the best interests of our clients. We recognize that this duty requires us to vote client securities in a timely manner and make voting decisions that are in the best interests of our clients. Consistent with these obligations, we will disclose our clients' voting records only to them and as required by mutual fund vote disclosure regulations. In addition, the proxy committees may, after careful consideration, choose to respond to surveys regarding past votes. This statement is intended to comply with Rule 206(4)-6 of the Investment Advisers Act of 1940. It sets forth our policies and procedures for voting proxies for our discretionary investment advisory clients, including investment companies registered under the Investment Company Act of 1940. This statement applies to Alliance Capital's growth and value investment groups investing on behalf of clients in both US and non-US securities. Proxy Policies This statement is designed to be responsive to the wide range of proxy voting subjects that can have a significant effect on the investment value of the securities held in our clients' accounts. These policies are not exhaustive due to the variety of proxy voting issues that we may be required to consider. Alliance Capital reserves the right to depart from these guidelines in order to avoid voting decisions that we believe may be contrary to our clients' best interests. In reviewing proxy issues, we will apply the following general policies: Corporate Governance: Alliance Capital's proxy voting policies recognize the importance of good corporate governance in ensuring that management and the board of directors fulfill their obligations to the shareholders. We favor proposals promoting transparency and accountability within a company. We will vote for proposals providing for equal access to the proxy materials so that shareholders can express their views on various proxy issues. We also support the appointment of a majority of independent directors on key committees and separating the positions of chairman and chief executive officer. Elections of Directors: Unless there is a proxy fight for seats on the Board or we determine that there are other compelling reasons for withholding votes for directors, we will vote in favor of the management proposed slate of directors. That said, we believe that directors have a duty to respond to shareholder actions that have received significant shareholder support. We may withhold votes for directors that fail to act on key issues such as failure to implement proposals to declassify boards, failure to implement a majority vote requirement, failure to submit a rights plan to a shareholder vote or failure to act on tender offers where a majority of shareholders have tendered their shares. In addition, we will withhold votes for directors who fail to attend at least seventy-five percent of board meetings within a given year without a reasonable excuse. Finally, we may withhold votes for directors of non-U.S. issuers where there is insufficient information about the nominees disclosed in the proxy statement. Appointment of Auditors: Alliance Capital believes that the company remains in the best position to choose the auditors and will generally support management's recommendation. However, we recognize that there may be inherent conflicts when a company's independent auditor performs substantial nonaudit related services for the company. While we will recognize that there may be special circumstances that could lead to high non-audit fees in some years, we would normally consider non-audit fees in excess of 70% to be disproportionate. Therefore, we may vote against the appointment of auditors if the fees for non-audit related services exceed 70% of the total audit fees paid by the company or there are other reasons to question the independence of the company's auditors. Changes in Legal and Capital Structure: Changes in a company's charter, articles of incorporation or by-laws are often technical and administrative in nature. Absent a compelling reason to the contrary, Alliance Capital will cast its votes in accordance with the company's management on such proposals. However, we will review and analyze on a case-by-case basis any non-routine proposals that are likely to affect the structure and operation of the company or have a material economic effect on the company. For example, we will generally support proposals to increase authorized common stock when it is necessary to implement a stock split, aid in a restructuring or acquisition or provide a sufficient number of shares for an employee savings plan, stock option or executive compensation plan. However, a satisfactory explanation of a company's intentions must be disclosed in the proxy statement for proposals requesting an increase of greater than one hundred percent of the shares outstanding. We will oppose increases in authorized common stock where there is evidence that the shares will be used to implement a poison pill or another form of anti-takeover device, or if the issuance of new shares could excessively dilute the value of the outstanding shares upon issuance. Corporate Restructurings, Mergers and Acquisitions: Alliance Capital believes proxy votes dealing with corporate reorganizations are an extension of the investment decision. Accordingly, we will analyze such proposals on a case-by-case basis, weighing heavily the views of the research analysts that cover the company and the investment professionals managing the portfolios in which the stock is held. Proposals Affecting Shareholder Rights: Alliance Capital believes that certain fundamental rights of shareholders must be protected. We will generally vote in favor of proposals that give shareholders a greater voice in the affairs of the company and oppose any measure that seeks to limit those rights. However, when analyzing such proposals we will weigh the financial impact of the proposal against the impairment of shareholder rights. Anti-Takeover Measures: Alliance Capital believes that measures that impede takeovers or entrench management not only infringe on the rights of shareholders but may also have a detrimental effect on the value of the company. We will generally oppose proposals, regardless of whether they are advanced by management or shareholders, the purpose or effect of which is to entrench management or dilute shareholder ownership. Conversely, we support proposals that would restrict or otherwise eliminate antitakeover measures that have already been adopted by corporate issuers. For example, we will support shareholder proposals that seek to require the company to submit a shareholder rights plan to a shareholder vote. We will evaluate, on a case-by-case basis, proposals to completely redeem or eliminate such plans. Furthermore, we will generally oppose proposals put forward by management (including blank check preferred stock, classified boards and supermajority vote requirements) that appear to be intended as management entrenchment mechanisms. Executive Compensation: Alliance Capital believes that company management and the compensation committee of the board of directors should, within reason, be given latitude to determine the types and mix of compensation and benefit awards offered. Whether proposed by a shareholder or management, we will review proposals relating to executive compensation plans on a case-by-case basis to ensure that the long-term interests of management and shareholders are properly aligned. We will analyze the proposed plans to ensure that shareholder equity will not be excessively diluted, the option exercise price is not below market price on the date of grant and an acceptable number of employees are eligible to participate in such programs. We will generally oppose plans that permit repricing of underwater stock options without shareholder approval. Other factors such as the company's performance and industry practice will generally be factored into our analysis. We will support proposals to submit severance packages that do not exceed 2.99 times the sum of an executive officer's base salary plus bonus that are triggered by a change in control to a shareholder vote. Finally, we will support shareholder proposals requiring companies to expense stock options because we view them as a large corporate expense. Social and Corporate Responsibility: Alliance Capital will review and analyze on a case-by-case basis proposals relating to social, political and environmental issues to determine whether they will have a financial impact on shareholder value. We will vote against proposals that are unduly burdensome or result in unnecessary and excessive costs to the company. We may abstain from voting on social proposals that do not have a readily determinable financial impact on shareholder value. Proxy Voting Procedures Proxy Voting Committees Our growth and value investment groups have formed separate proxy voting committees to establish general proxy policies for Alliance Capital and consider specific proxy voting matters as necessary. These committees periodically review these policies and new types of corporate governance issues, and decide how we should vote on proposals not covered by these policies. When a proxy vote cannot be clearly decided by an application of our stated policy, the proxy committee will evaluate the proposal. In addition, the committees, in conjunction with the analyst that covers the company, may contact corporate management and interested shareholder groups and others as necessary to discuss proxy issues. Members of the committee include senior investment personnel and representatives of the Legal and Compliance Department. The committees may also evaluate proxies where we face a potential conflict of interest (as discussed below). Finally, the committees monitor adherence to these policies. Conflicts of Interest Alliance Capital recognizes that there may be a potential conflict of interest when we vote a proxysolicited by an issuer whose retirement plan we manage, or we administer, who distributes Alliance Capital sponsored mutual funds, or with whom we or an employee has another business or personal relationship that may affect how we vote on the issuer's proxy. Similarly, Alliance may have a potential material conflict of interest when deciding how to vote on a proposal sponsored or supported by a shareholder group that is a client. We believe that centralized management of proxy voting, oversight by the proxy voting committees and adherence to these policies ensures that proxies are voted with only our clients' best interests in mind. That said, we have implemented additional procedures to ensure that our votes are not the product of a material conflict of interests, including: (i) on an annual basis, the proxy committees will take reasonable steps to evaluate the nature of Alliance Capital's and our employees' material business and personal relationships (and those of our affiliates) with any company whose equity securities are held in client accounts and any client that has sponsored or has material interest in a proposal upon which we will be eligible to vote; (ii) requiring anyone involved in the decision making process to disclose to the chairman of the appropriate proxy committee any potential conflict that they are aware of (including personal relationships) and any contact that they have had with any interested party regarding a proxy vote; (iii) prohibiting employees involved in the decision making process or vote administration from revealing how we intend to vote on a proposal in order to reduce any attempted influence from interested parties; and (iv) where a material conflict of interests exists, reviewing our proposed vote by applying a series of objective tests and, where necessary, considering the views of a third party research service to ensure that our voting decision is consistent with our clients' best interests. Because under certain circumstances Alliance Capital considers the recommendation of third party research services, the proxy committees will take reasonable steps to verify that any third party research service is in fact independent based on all of the relevant facts and circumstances. This includes reviewing the third party research service's conflict management procedures and ascertaining, among other things, whether the third party research service (i) has the capacity and competency to adequately analyze proxy issues; and (ii) can make such recommendations in an impartial manner and in the best interests of our clients. Proxies of Certain Non-US Issuers Proxy voting in certain countries requires "share blocking." Shareholders wishing to vote their proxies must deposit their shares shortly before the date of the meeting (usually one-week) with a designated depositary. During this blocking period, shares that will be voted at the meeting cannot be sold until the meeting has taken place and the shares are returned to the clients' custodian banks. Alliance Capital may determine that the benefit to the client of exercising the vote does not outweigh the cost of voting, which is not being able to transact in the shares during this period. Accordingly, if share blocking is required we may abstain from voting those shares. In addition, voting proxies of issuers in non-US markets may give rise to a number of administrative issues that may prevent Alliance Capital from voting such proxies. For example, Alliance Capital may receive meeting notices without enough time to fully consider the proxy or after the cut-off date for voting. Other markets require Alliance Capital to provide local agents with power of attorney prior to implementing Alliance Capital's voting instructions. Although it is Alliance Capital's policy to seek to vote all proxies for securities held in client accounts for which we have proxy voting authority, in the case of non-US issuers, we vote proxies on a best efforts basis. Proxy Voting Records Clients may obtain information about how we voted proxies on their behalf by contacting their Alliance Capital administrative representative. Alternatively, clients may make a written request for proxy voting information to: Mark R. Manley, Senior Vice President & Chief Compliance Officer, Alliance Capital Management L.P., 1345 Avenue of the Americas, New York, NY 10105. ITEM 8.
