June 19, 2006 Semi-Annual Report This report provides management's discussion of fund performance for the portfolios of AllianceBernstein Municipal Income Fund (the "Portfolios") for the semi-annual reporting period ended April 30, 2006. Investment Objective and Policies The investment objective of the five portfolios of this open-end fund is to earn the highest level of current income, exempt from Federal taxation and, in the case of the State Portfolios, state taxation of the respective state that is available without assuming undue risk. Each portfolio invests principally in high-yielding, predominantly investment-grade municipal securities with interest that is exempt from federal income tax, although these securities may pay interest that is subject to the federal Alternative Minimum Tax ("AMT") for certain taxpayers. The Insured National Portfolio and the Insured California Portfolio invest principally in municipal securities paying interest that is wholly exempt from federal income taxes, including the AMT, whereas the other AllianceBernstein Municipal Portfolios may invest without limit in municipal securities paying interest subject to AMT. The average weighted maturity of the securities in each AllianceBernstein Municipal Portfolio will normally range between 10 and 30 years. Investment Results The table on page 5 shows performance for each Portfolio compared to its benchmark, the Lehman Brothers (LB) Municipal Index, for the six- and 12-month periods ended April 30, 2006. For both the six- and 12-month periods ended April 30, 2006, the National, California and New York Portfolios' Class A shares outperformed the benchmark, the LB Municipal Index, which represents the municipal market and posted positive returns of 1.56% and 2.16% for the respective time periods. The Insured California Portfolio underperformed the benchmark during the same time frames. The Insured National Portfolio underperformed the benchmark for the six-month period and performed in line with the benchmark during the 12-month period. A description of each Portfolio's relative performance versus the benchmark for the six-month period ended April 30, 2006 follows. National Portfolio--The National Portfolio's stronger relative performance was largely the result of security selection in the insured and special tax sectors. The Portfolio also benefited from its relative weight in the hospital sector. Security selection in the power sector detracted from the Portfolio's performance. In addition, the Portfolio's holdings in lower-rated bonds benefited performance relative to the benchmark. California Portfolio--The California Portfolio's stronger relative performance was largely the result of security selection in the special tax and general obligation sectors. In addition, the Portfolio's holdings in lower-rated bonds benefited performance relative to the benchmark. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 1 New York Portfolio--The New York Portfolio's stronger relative performance was largely the result of security selection in the insured and special tax sectors. Security selection in the housing and industrial development revenue bond sectors detracted from the Portfolio's performance. In addition, the Portfolio's holdings in lower-rated bonds benefited performance relative to the benchmark. Insured National Portfolio--The Insured National Portfolio's relative underperformance was largely the result of a lack of exposure to lower-credit quality bonds. Insured California Portfolio--The Insured California Portfolio's relative underperformance was largely the result of a lack of exposure to lower-credit quality bonds. Market Review and Investment Strategy From April 2005 through the end of April 2006, the U.S. Federal Reserve (the "Fed") raised the target for the Federal funds rate from 2.75% to 4.75%; 0.75% of that increase was since October 2005. In response to the Fed's actions, the yields for most maturities of domestic bonds increased. Municipal bond yields increased less than U.S. Treasury bond yields. For example, during the six-month reporting period, 10-year municipal yields increased 0.16% and 30-year municipal yields actually declined 0.06%. Over the same time period, 10-year and 30-year U.S. Treasury bond yields rose 0.50% and 0.46%, respectively. The outperformance for municipal bonds largely resulted from relatively light supply-the amount of bonds issued in the first quarter of 2006 was down 29% from the first quarter of 2005. Municipal bond prices have also been supported by ongoing demand from a diverse set of investors including traditional buyers such as U.S. individuals, as well as relatively newer municipal market participants, such as hedge funds and other institutional leveraged investors. The municipal market showed similar relative performance over the 12-month period as over the six-month period ended April 30, 2006. For the 12-month period, despite 10-year U.S. Treasury yields increasing 0.85% and 30-year U.S. Treasury yields increasing 0.66%, 10-year and 30-year municipal yields rose 0.51% and 0.16%, respectively. The market for lower-credit quality, or high yield, municipal bonds continues to post even stronger returns than the general municipal market. The LB High Yield Municipal Index returned 5.23% and 7.46% over the six- and 12-month periods ended April 30, 2006, respectively. This compares to 1.56% and 2.16% for the same periods for the LB Municipal Bond Index, which represents the overall general market for investment-grade municipal bonds. The strong performance for lower-credit quality municipal bonds was in part due to the relatively favorable credit environment, but of more importance, due to the continued, very strong demand for higher-yielding bonds. According to AMG Data, a provider of mutual fund money flow and holdings data, new money into high yield municipal bond mutual funds accounted for approximately 40% of the flow in municipal bond mu- 2 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND tual funds during the first quarter of 2006. By comparison, high yield bonds currently represent about 4% of the outstanding supply of municipal bonds. During the past year, the Municipal Bond Investment Team's (the "team's") strategy has remained consistent. Given that interest rates are still relatively low compared to the level of inflation, the team continues to maintain less interest rate exposure than in the Portfolios' relative to that of the Portfolios' benchmark. Also, because high yield municipals have displayed such strong performance, the team has reduced the Portfolios' exposure to such holdings, and further diversified the Portfolios' remaining holdings. Recently, as market conditions allow, the team has also been selling longer-maturity holdings and replacing them with bonds with shorter maturities. In the team's view, these shorter-maturity holdings should outperform longer-maturity bonds if rates rise and the difference between long and short yields increases. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 3 HISTORICAL PERFORMANCE An Important Note About the Value of Historical Performance The performance shown on the following pages represents past performance and does not guarantee future results. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by visiting www.alliancebernstein.com. The investment return and principal value of an investment in the Portfolios will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. You should consider the investment objectives, risks, charges and expenses of the Portfolios carefully before investing. For a free copy of the Portfolios' prospectus, which contains this and other information, visit our web site at www.alliancebernstein.com or call your financial advisor or AllianceBernstein Investments at (800) 227-4618. You should read the prospectus carefully before you invest. Returns are annualized for periods longer than one year. All fees and expenses related to the operation of the Portfolios have been deducted. NAV returns do not reflect sales charges; if sales charges were reflected, the Portfolios' quoted performance would be lower. SEC returns reflect the applicable sales charges for each share class: a 4.25% maximum front-end sales charge for Class A shares; the applicable contingent deferred sales charge for Class B shares (3% year 1, 2% year 2, 1% year 3, 0% year 4); a 1% 1 year contingent deferred sales charge for Class C shares. Returns for the different share classes will vary due to different expenses associated with each class. Performance assumes reinvestment of distributions and does not account for taxes. During the reporting period, the Adviser waived a portion of its advisory fee or reimbursed the Portfolio for a portion of its expenses to the extent necessary to limit National Portfolio's expenses on an annual basis to 0.68%, 1.38% and 1.38% of the average daily net assets of Class A, Class B and Class C shares, respectively. During the reporting period, the Adviser waived a portion of its advisory fee or reimbursed the Portfolio for a portion of its expenses to the extent necessary to limit California Portfolio's expenses on an annual basis to 0.77%, 1.47% and 1.47% of the average daily net assets of Class A, Class B and Class C shares, respectively. During the reporting period, the Adviser waived a portion of its advisory fee or reimbursed the Portfolio for a portion of its expenses to the extent necessary to limit New York Portfolio's expenses on an annual basis to 0.58%, 1.28% and 1.28% of the average daily net assets of Class A, Class B and Class C shares, respectively. During the reporting period, the Adviser waived a portion of its advisory fee or reimbursed the Portfolio for a portion of its expenses to the extent necessary to limit Insured National Portfolio's expenses on an annual basis to 1.04%, 1.74% and 1.74% of the average daily net assets of Class A, Class B and Class C shares, respectively. These waivers extend through the Portfolios' current fiscal year and may be extended by the Adviser for additional one-year terms. Without the waivers, the Portfolios' expenses would have been higher and their performance would have been lower than that shown. 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. An investor cannot invest directly in an index, and its results are not indicative of the performance for any specific investment, including the Portfolios. A Word About Risk Price fluctuation in the Portfolios' securities may be caused by changes in the general level of interest rates or changes in bond credit quality ratings. Changes in interest rates have a greater effect on bonds with longer maturities than on those with shorter maturities. Please note, as interest rates rise, existing bond prices fall and can cause the value of an investment in the Portfolios to decline. Individual state municipal portfolios are non-diversified and are subject to geographic risk based on their narrow investment objectives. The Portfolios may invest in high yield bonds (i.e., junk bonds) which involves a greater risk of default and price volatility than other bonds. Investing in non-investment grade presents special risks, including credit risk. While the Portfolios invest principally in bonds and other fixed-income securities, in order to achieve their investment objectives, the Portfolios 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. These risks are fully discussed in the Portfolios' prospectus.

See Historical Performance disclosures on page 4. 10 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND FUND EXPENSES As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period as indicated below. Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed annual rate of return of 5% before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds by comparing this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), or contingent deferred sales charges on redemptions. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(the "Fund"), is registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund, which is a Maryland corporation, operates as a series company currently comprised of the diversified National Portfolio, Insured National Portfolio, New York Portfolio and California Portfolio and the non-diversified Insured California Portfolio (the "Portfolios"). Each series is considered to be a separate entity for financial reporting and tax purposes. Each Portfolio offers three classes of shares: Class A, Class B and Class C Shares. Class A shares are sold with a front-end sales charge of up to 4.25% for purchases not exceeding $1,000,000. With respect to purchases of $1,000,000 or more, Class A shares redeemed within one year of purchase may be subject to a contingent deferred sales charge of 1%. Class B shares are currently sold with a contingent deferred sales charge which declines from 3% to zero depending on the period of time the shares are held. Class B shares will automatically convert to Class A shares six years after the end of the calendar month of purchase. Class C shares are subject to a contingent deferred sales charge of 1% on redemptions made within the first year after purchase. All three classes of shares have identical voting, dividend, liquidation and other rights, except that each class bears different distribution expenses and has exclusive voting rights with respect to its distribution plan. 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. Additional information about some of the items discussed in these notes to financial statements is contained in the Fund's Statement of Additional Information, which is available upon request. 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 values 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 ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 69 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, AllianceBernstein L.P. (prior to February 24, 2006 known as Alliance Capital Management L.P.) (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 (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 each Portfolio'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 trade date securities are purchased or sold. As described more fully in the prospectus for the Portfolios, each portfolio may buy and sell securities from 70 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND other affiliated funds in accordance with the requirements of Rule 17a-7 of the Investment Company Act of 1940. Each Portfolio has adopted procedures to ensure that all such transactions are done in accordance with the requirements of Rule 17a-7. Investment gains and losses are determined on the identified cost basis. The Portfolios amortize premiums and accrete original issue discount and market discount as adjustments to interest income. The New York, Insured California and California Portfolios follow an investment policy of investing primarily in municipal obligations of one state. Economic changes affecting the state and certain of its public bodies and municipalities may affect the ability of issuers within the state to pay interest on, or repay principal of, municipal obligations held by the Portfolios. 4. Class Allocations All income earned and expenses incurred by the Portfolios are borne on a pro-rata basis by each settled class of shares, based on proportionate interest in each Portfolio represented by the net assets of such class, except for class specific expenses which are allocated to the respective class. Expenses of the Fund are charged to each Portfolio in proportion to net assets. Realized and unrealized gains and losses are allocated among the various share classes based on relative net assets. 5. Dividends and Distributions Dividends and distributions to shareholders, if any, are recorded on the ex-dividend date. Income dividends 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 Fee and Other Transactions with Affiliates Under the terms of the investment advisory agreement, the Fund pays the Adviser an advisory fee at an annual rate of .45% of the first $2.5 billion, .40% of the next $2.5 billion and .35% in excess of $5 billion, of each Portfolio's average daily net assets. Prior to September 7, 2004, the National, New York and California Portfolios paid the Adviser an advisory fee at an annual rate of ..625% of each Portfolio's average daily net assets. For the Insured National Portfolio, the Agreement provided for a fee at an annual rate of up to .625% of the first $200 million, .50% of the next $200 million and .45% in excess of $400 million of its average daily net assets. For the Insured California Portfolio, the Agreement provided for a fee at an annual rate of up to .55% of the first $200 million, .50% of the next $200 million and .45% in excess of $400 million of its average daily net assets. Such fee is accrued daily and paid monthly. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 71 Effective June 16, 2004, the Adviser has agreed to waive its fees and bear certain expenses to the extent necessary to limit the total portfolio operating expenses on an annual basis as follows: Portfolios Class A Class B Class C - -------------------------------------------------------- National .68% 1.38% 1.38% Insured National 1.04% 1.74% 1.74% New York .58% 1.28% 1.28% California .77% 1.47% 1.47% For the six months ended April 30, 2006, such reimbursement waivers amounted to $559,423, $7,427, $775,087 and $396,890 for National, Insured National, New York and California Portfolios, respectively. Pursuant to the advisory agreement, the National, Insured National, New York, California and Insured California Portfolios each paid $38,000 to the Adviser representing the cost of certain legal and accounting services provided to each portfolio by the Adviser for the six months ended April 30, 2006. Each Portfolio compensates AllianceBernstein Investor Services, Inc. (prior to February 24, 2006 known as Alliance Global Investor Services, Inc.) ("ABIS"), a wholly-owned subsidiary of the Adviser, under a Transfer Agency Agreement for providing personnel and facilities to perform transfer agency services for each Portfolio. ABIS may make payments to intermediaries that provide omnibus account services, sub-accounting services and/or networking services. Such compensation retained by ABIS amounted to: National Portfolio, $121,326; Insured National Portfolio, $30,170; New York Portfolio, $83,012; California Portfolio, $88,548 and Insured California Portfolio, $13,525 for the six months ended April 30, 2006. For the six months ended April 30, 2006, the Fund's expenses were reduced by: National Portfolio $3,967; Insured National Portfolio $1,139; New York Portfolio $3,294; California Portfolio $3,919 and Insured California Portfolio, $562 under an expense offset arrangement with ABIS. AllianceBernstein Investments, Inc. (prior to February 24, 2006 known as AllianceBernstein Investment Research and Management, Inc.) (the "Distributor"), a wholly-owned subsidiary of the Adviser, serves as the distributor of the Fund's shares. The Distributor has advised the Fund that it has received front-end sales charges from sales of Class A shares and contingent deferred sales 72 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND charges imposed upon redemptions by shareholders of Class A, Class B and Class C shares for the six months ended April 30, 2006 as follows: Front-End Contingent Deferred Sales Charges Sales Charges ------------------------------------ Portfolio Class A Class A Class B Class C - -------------------------------------------------------------------------- National $ 14,848 $ 4,182 $ 9,309 $ 2,930 Insured National 2,848 6,461 8,659 143 New York 25,124 4,237 43,784 6,548 California 16,603 793 21,472 3,517 Insured California 2,084 110 2,880 71 Accrued expenses for the National Portfolio includes $561 owed to a director under the trust's deferred compensation plan. NOTE C Distribution Services Agreement The Fund has adopted a Distribution Services Agreement (the "Agreement") pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the Agreement, each Portfolio pays distribution and servicing fees to the Distributor at an annual rate of up to .30 of 1% of each Portfolio's average daily net assets attributable to the Class A shares and 1% of each Portfolio's average daily net assets attributable to both Class B and Class C shares. The fees are accrued daily and paid monthly. The Agreement provides that the Distributor will use such payments in their entirety for distribution assistance and promotional activities. The Distributor has incurred expenses in excess of the distribution costs reimbursed by each Portfolio as follows: Portfolio Class B Class C - ----------------- -------------- -------------- National $ 4,013,869 $ 4,723,793 Insured National 3,649,798 1,912,883 New York 7,598,394 2,758,022 California 7,436,228 5,662,929 Insured California 3,111,801 1,771,767 Such costs may be recovered from each Portfolio in future periods so long as the Agreement is in effect. In accordance with the Agreement, there is no provision for recovery of unreimbursed distribution costs incurred by the Distributor beyond the current fiscal year for Class A shares. The Agreement also provides that the Adviser may use its own resources to finance the distribution of each Portfolio's shares. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 73 NOTE D Investment Transactions Purchases and sales of investment securities (excluding short-term investments) for the six months ended April 30, 2006 were as follows: Portfolio Purchases Sales - ----------------- -------------- -------------- National $ 65,074,197 $ 63,671,939 Insured National 10,968,433 13,804,490 New York 120,707,700 128,675,763 California 31,246,651 74,331,443 Insured California 3,915,220 12,421,661 There were no purchases or sales of U.S. government and government agency obligations for the six months ended April 30, 2006. 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 futures and swap transactions) are as follows: Gross Unrealized Net --------------------------------- Unrealized Portfolio Appreciation (Depreciation) Appreciation - ------------------------------------------------------------------------------- National $ 16,770,409 $ (1,739,969) $ 15,030,440 Insured National 7,897,120 (178,077) 7,719,043 New York 15,923,831 (2,166,699) 13,757,132 California 48,642,093 (1,526,981) 47,115,112 Insured California 5,497,748 (311,359) 5,186,389 1. Financial Futures Contracts The Fund may buy or sell financial futures contracts for the purpose of hedging its portfolio against adverse affects of anticipated movements in the market. The Fund bears the market risk that arises from changes in the value of these financial instruments and the imperfect correlation between movements in the price of the futures contracts and movements in the price of the securities hedged or used for cover. At the time the Fund enters into a futures contract, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the con- 74 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND tract. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed. 2. Swap Agreements The Fund may enter into swaps to hedge its exposure to interest rates and credit risk or 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 specified 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 a counterparty is generally limited to the net interim 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. 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 E Capital Stock The Fund has allocated 9,100,000,000 of authorized shares each to the National Portfolio and Insured National Portfolio and 9,050,000,000 of authorized shares each to the New York Portfolio, California Portfolio and Insured Califor- ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 75 nia Portfolio.

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. 80 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND NOTE G Joint Credit Facility A number of open-end mutual funds managed by the Adviser, including the Fund, participate in a $250 million revolving credit facility (the "Facility") intended to provide short-term financing if necessary, subject to certain restrictions, in connection with abnormal redemption activity. Commitment fees related to the Facility are paid by the participating funds and are included in miscellaneous expenses in the statement of operations. The Fund did not utilize the Facility during the six months ended April 30, 2006.

NOTE I Legal Proceedings As has been previously reported, the staff of the U.S. Securities and Exchange Commission ("SEC") and the 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. 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 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 84 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND 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 until December 31, 2008; and (iii) The Adviser agreed to implement changes to its governance and compliance procedures. Additionally, the SEC Order and the NYAG Order contemplate that the Adviser's registered investment company clients, including the Fund, will introduce governance and compliance changes. In anticipation of final, definitive documentation of the NYAG Order and effective January 1, 2004, the Adviser began waiving a portion of its advisory fee. On September 7, 2004, the Fund's investment advisory agreement was amended to reflect the reduced advisory fee. For more information on this waiver and amendment to the Fund's investment advisory agreement, please see "Advisory Fee and Other Transactions with Affiliates" above. A special committee of the Adviser's Board of Directors, comprised of the members of the Adviser's Audit Committee and the other independent member of the Adviser's Board, directed and oversaw an internal investigation and a comprehensive review of the facts and circumstances relevant to the SEC's and the NYAG's investigations. In addition, the Independent Directors of the Fund ("the Independent Directors") have initiated an investigation of the above-mentioned matters with the advice of an independent economic consultant and independent counsel. The Independent Directors have formed a special committee to supervise the investigation. On October 2, 2003, a purported class action complaint entitled Hindo, et al. v. AllianceBernstein Growth & Income Fund, et al. ("Hindo Complaint") was filed against the Adviser, Alliance Capital Management Holding L.P. ("Alliance Holding"), Alliance Capital Management Corporation, AXA Financial, Inc., the AllianceBernstein Funds, certain officers of the Adviser ("Alliance defendants"), and certain other defendants not affiliated with the Adviser, as well as unnamed Doe defendants. The Hindo Complaint was filed in the United States District Court for the Southern District of New York by alleged shareholders of two of the AllianceBernstein Funds. The Hindo Complaint alleges that certain of the Alliance defendants failed to disclose that they improperly allowed certain hedge funds and other unidentified parties to engage in "late trading" and "market timing" of AllianceBernstein Fund securities, violating Sections 11 and 15 of the ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 85 Securities Act, Sections 10(b) and 20(a) of the Exchange Act and Sections 206 and 215 of the Advisers Act. Plaintiffs seek an unspecified amount of compensatory damages and rescission of their contracts with the Adviser, including recovery of all fees paid to the Adviser pursuant to such contracts. Since October 2, 2003, 43 additional lawsuits making factual allegations generally similar to those in the Hindo Complaint were filed in various federal and state courts against the Adviser and certain other defendants. The plaintiffs in such lawsuits have asserted a variety of theories for recovery including, but not limited to, violations of the Securities Act, the Exchange Act, the Advisers Act, the Investment Company Act, the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), certain state securities laws and common law. All state court actions against the Adviser either were voluntarily dismissed or removed to federal court. On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred all actions to the United States District Court for the District of Maryland (the "Mutual Fund MDL"). On September 29, 2004, plaintiffs filed consolidated amended complaints with respect to four claim types: mutual fund shareholder claims; mutual fund derivative claims; derivative claims brought on behalf of Alliance Holding; and claims brought under ERISA by participants in the Profit Sharing Plan for Employees of the Adviser. All four complaints include substantially identical factual allegations, which appear to be based in large part on the SEC Order and the NYAG Order. The claims in the mutual fund derivative consolidated amended complaint are generally based on the theory that all fund advisory agreements, distribution agreements and 12b-1 plans between the Adviser and the AllianceBernstein Funds should be invalidated, regardless of whether market timing occurred in each individual fund, because each was approved by fund trustees on the basis of materially misleading information with respect to the level of market timing permitted in funds managed by the Adviser. The claims asserted in the other three consolidated amended complaints are similar to those that the respective plaintiffs asserted in their previous federal lawsuits. All of these lawsuits seek an unspecified amount of damages. On April 21, 2006, the Adviser and attorneys for the plaintiffs in the mutual fund shareholder claims, mutual fund derivative claims, and ERISA claims entered into a confidential memorandum of understanding ("MOU") containing their agreement to settle these claims. The agreement will be documented by a stipulation of settlement and will be submitted for court approval at a later date. On February 10, 2004, the Adviser received (i) a subpoena duces tecum from the Office of the Attorney General of the State of West Virginia and (ii) a request for information from West Virginia's Office of the State Auditor, Securities Commission (the "West Virginia Securities Commissioner") (together, the "In- 86 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND formation Requests"). Both Information Requests require the Adviser to produce documents concerning, among other things, any market timing or late trading in the Adviser's sponsored mutual funds. The Adviser responded to the Information Requests and has been cooperating fully with the investigation. On April 11, 2005, a complaint entitled The Attorney General of the State of West Virginia v. AIM Advisors, Inc., et al. ("WVAG Complaint") was filed against the Adviser, Alliance Holding, and various other defendants not affiliated with the Adviser. The WVAG Complaint was filed in the Circuit Court of Marshall County, West Virginia by the Attorney General of the State of West Virginia. The WVAG Complaint makes factual allegations generally similar to those in the Hindo Complaint. On October 19, 2005, the WVAG Complaint was transferred to the Mutual Fund MDL. On August 30, 2005, the deputy commissioner of securities of the West Virginia Securities Commissioner signed a Summary Order to Cease and Desist, and Notice of Right to Hearing addressed to the Adviser and Alliance Holding. The Summary Order claims that the Adviser and Alliance Holding violated the West Virginia Uniform Securities Act, and makes factual allegations generally similar to those in the Commission Order and the NYAGOrder. On January 26, 2006, the Adviser, Alliance Holding, and various unaffiliated defendants filed a Petition for Writ of Prohibition and Order Suspending Proceedings in West Virginia state court seeking to vacate the Summary Order and for other relief. On April 12, 2006, respondents' petition was denied. On May 4, 2006, respondents appealed the court's determination. 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 Holding, Alliance Capital Management Corporation, AXA Financial, Inc., AllianceBernstein Investment Research & Management, Inc., certain current and former directors of the 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 alleged shareholders 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 ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 87 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, nine additional lawsuits making factual allegations substantially similar to those in the Aucoin Complaint were filed against the Adviser and certain other defendants. All nine of the lawsuits (i) were brought as class actions filed in the United States District Court for the Southern District of New York, (ii) assert claims substantially identical to the Aucoin Complaint, and (iii) are brought on behalf of shareholders of the Funds. On February 2, 2005, plaintiffs filed a consolidated amended class action complaint ("Aucoin Consolidated Amended Complaint") that asserts claims substantially similar to the Aucoin Complaint and the nine additional lawsuits referenced above. On October 19, 2005, the District Court dismissed each of the claims set forth in the Aucoin Consolidated Amended Complaint, except for plaintiffs' claim under Section 36(b) of the Investment Company Act. On January 11, 2006, the District Court granted defendants' motion for reconsideration and dismissed the remaining Section 36(b) claim. On May 31, 2006 the District Court denied plaintiffs' motion for leave to file an amended complaint. It is possible that these matters and/or other developments resulting from these matters could result in increased redemptions of the AllianceBernstein Mutual Funds' shares or other adverse consequences to the AllianceBernstein Mutual Funds. This may require the AllianceBernstein Mutual Funds to sell investments held by those funds to provide for sufficient liquidity and could also have an adverse effect on the investment performance of the AllianceBernstein Mutual Funds. However, the Adviser believes that these matters are not likely to have a material adverse effect on its ability to perform advisory services relating to the AllianceBernstein Mutual Funds. 88 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND FINANCIAL HIGHLIGHTS Selected Data For A Share Of Capital Stock Outstanding Throughout Each Period National Portfolio ------------------------------------------------------------------------------- Class A ------------------------------------------------------------------------------- Six Months Ended April 30, Year Ended October 31, 2006 --------------------------------------------------------------- (unaudited) 2005 2004(a) 2003 2002 2001 ----------- ----------- ----------- ----------- ----------- ----------- Net asset value, beginning of period $10.05 $10.13 $9.96 $9.80 $10.34 $10.14 Income From Investment Operations Net investment income(b)(c) .23 .47 .50 .52 .54 .54 Net realized and unrealized gain (loss) on investment transactions (.02) (.07) .17 .18 (.53) .21 Net increase in net asset value from operations .21 .40 .67 .70 .01 .75 Less: Dividends and Distributions Dividends from net investment income (.24) (.48) (.50) (.54) (.54) (.54) Distributions in excess of net investment income -0- -0- -0- -0- (.01) (.01) Total dividends and distributions (.24) (.48) (.50) (.54) (.55) (.55) Net asset value, end of period $10.02 $10.05 $10.13 $9.96 $9.80 $10.34 Total Return Total investment return based on net asset value(d) 2.05% 3.95% 6.92% 7.32% .06% 7.55% Ratios/Supplemental Data Net assets, end of period (000's omitted) $341,428 $337,201 $344,557 $373,416 $411,408 $425,506 Ratio to average net assets of: Expenses, net of fee waivers .68%(e)(f) .68% .68% .68% .65% .64% Expenses, before fee waivers .93%(e)(f) .93% 1.08% 1.11% 1.07% 1.06% Net investment income(b) 4.68%(e)(f) 4.65% 4.94% 5.25% 5.28% 5.22% Portfolio turnover rate 15% 25% 47% 35% 63% 194% See footnote summary on page 104.

(the "Adviser") and AllianceBernstein Municipal Income Fund, Inc. on behalf of California Portfolio, Insured California Portfolio, National Portfolio, Insured National Portfolio and New York Portfolio (each a "Fund" and collectively the "Funds"), prepared by Philip L. Kirstein, the Senior Officer, for the independent directors of the Funds, as required by the Assurance of Discontinuance between the New York State Attorney General and the Adviser. The Senior Officer's evaluation of the investment advisory agreement is not meant to diminish the responsibility or authority of the Board of Directors of the Funds to perform its duties pursuant to Section 15 of the Investment Company Act of 1940 (the "40 Act") and applicable state law. The purpose of the summary is to provide shareholders with a synopsis of the independent evaluation of the reasonableness of the advisory fees which was provided to the independent directors in connection with their review of the proposed continuance of the investment advisory agreement. The Senior Officer's evaluation considered the following factors: 1. Management fees charged to institutional and other clients of the Adviser for like services. 2. Management fees charged by other mutual fund companies for like services. 3. Costs to the Adviser and its affiliates of supplying services pursuant to the advisory agreements, excluding any intra-corporate profit. 4. Profit margins of the Adviser and its affiliates from supplying such services. 5. Possible economies of scale as the Funds grow larger. 6. Nature and quality of the Adviser's services including the performance of the Funds. (1) It should be noted that the information in the fee summary was completed on September 2, 2005 and presented to the Board of Directors on September 14, 2005 in accordance with the Assurance of Discontinuance between the New York State Attorney General and the Adviser. It also should be noted that references in the fee summary pertaining to performance and expense ratios refer to Class A shares of the Funds. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 117 FUNDS ADVISORY FEES, EXPENSE REIMBURSEMENTS, CAPS & RATIOS The table below describes the Funds' advisory fees pursuant to the Investment Advisory Agreement. This is the fee schedule the Adviser implemented in January 2004 as a result of the settlement with the New York State Attorney General.(2) Advisory Fee Based on % of Fund Average Daily Net Assets - ------------------------------------------------------------------------------- California Portfolio First $2.5 billion 0.45% Next $2.5 billion 0.40% Excess of $5 billion 0.35% Insured California Portfolio First $2.5 billion 0.45% Next $2.5 billion 0.40% Excess of $5 billion 0.35% National Portfolio First $2.5 billion 0.45% Next $2.5 billion 0.40% Excess of $5 billion 0.35% Insured National Portfolio First $2.5 billion 0.45% Next $2.5 billion 0.40% Excess of $5 billion 0.35% New York Portfolio First $2.5 billion 0.45% Next $2.5 billion 0.40% Excess of $5 billion 0.35% The Adviser is reimbursed as specified in the Investment Advisory Agreement for certain clerical, legal, accounting, administrative and other services provided to the Funds as indicated below: As a % of average Fund Amount daily net assets - ------------------------------------------------------------------------------- California Portfolio $ 78,666 0.01 Insured California Portfolio $ 78,666 0.05 National Portfolio $ 78,666 0.02 Insured National Portfolio $ 78,666 0.04 New York Portfolio $ 78,666 0.02 The Adviser has agreed to waive that portion of its management fees and/or reimburse each Fund for that portion of its total operating expenses to the degree necessary to limit each Fund's expense ratio to the amounts set forth (2) The advisory fee schedule implemented in January 2004 contemplates eight categories of the AllianceBernstein Mutual Funds with all AllianceBernstein Funds in each category having the same advisory fee schedule. 118 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND below for each Fund's current fiscal year. The waiver agreement is terminable by the Adviser at the end of the Funds' fiscal year upon at least 60 days written notice.

The Fund does not have an expense cap pursuant to an expense limitation undertaking. Fund Expense Ratio Fiscal Year End - ------------------------------------------------------------------------------- Insured California Portfolio Class A-1.02% October 31 Class B-1.73% Class C-1.72% I. MANAGEMENT FEES CHARGED TO INSTITUTIONAL AND OTHER CLIENTS The management fees charged to investment companies which the Adviser manages and sponsors is normally higher than those charged to similar sized institutional accounts, including pension plans and sub-advised investment companies. The fee differential reflects, among other things, different services provided to such clients, and different liabilities assumed. Services provided by the Adviser to the Funds that are not provided to non-investment company clients include providing office space and personnel to serve as Fund Officers, who among other responsibilities make the certifications required under the SarbanesnOxley Act of 2002, and coordinating with and monitoring the Funds' third party service providers such as Fund counsel, auditors, custodians, transfer agents and pricing services. The accounting, administrative, legal and compliance requirements for (3) These gross expense ratios are calculated from the beginning of each Fund's current fiscal year through May 31, 2005. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 119 the Funds are more costly than those for institutional assets due to the greater complexities and time required for investment companies, although as previously noted, a portion of these expenses are reimbursed by the Funds to the Adviser. In addition, managing the cash flow of an investment company may be more difficult than that of a stable pool of assets, such as an institutional account with little cash movement in either direction, particularly, if a Fund is in net redemption and the Adviser is frequently forced to sell securities to raise cash for redemptions. However, managing a fund with positive cash flow may be easier at times than managing a stable pool of assets. Finally, in recent years, investment advisers have been sued by institutional clients and have suffered reputational damage both by the attendant publicity and outcomes other than complete victories. Accordingly, the legal and reputational risks associated with institutional accounts are greater than previously thought, although still not equal to those related to the mutual fund industry. Notwithstanding the Adviser's view that managing an investment company is not comparable to managing other institutional accounts because the services provided are different, it is worth considering information regarding the advisory fees charged to institutional accounts with substantially similar investment styles as the Funds. However, the Adviser represented that it does not manage any separate managed account that has similar investment guidelines as the Funds. The Adviser does manage separately managed accounts that invest principally in municipal securities but those mandates have a substantially lower risk profile (credit and interest rate risk) than the Funds. The Adviser manages the Sanford C. Bernstein Fund, Inc., an open-end investment company. The Adviser charges the following fees to the Portfolios that invest in municipal securities like the Funds, although they invest in securities of different maturities and qualities: Portfolio Advisory Fee - ------------------------------------------------------------------------------------------ California Municipal Portfolio 0.50% of the first $1 billion; Diversified Municipal Portfolio 0.45% in excess of $1 billion up to but New York Municipal Portfolio not exceeding $3 billion; 0.40% in excess of $3 billion Short Duration California Municipal Portfolio 0.50% of the first $250 million; Short Duration Diversified Municipal Portfolio 0.45% in excess of $250 million up to Short Duration New York Municipal Portfolio but not exceeding $750 million; 0.40% in excess of $750 million The Adviser also manages and sponsors retail mutual funds which are organized in jurisdictions outside the United States, generally Luxembourg, and sold to non-United States resident investors. The Adviser charges the following fees for an offshore mutual fund that invests in fixed income securities: 120 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND Asset Class Fee(4) - ------------------------------------------------------------------ Fixed Income 0.65% The Adviser represented that it does not sub-advise any registered investment companies of other fund families with a similar investment style as the Fund. II. MANAGEMENT FEES CHARGED BY OTHER MUTUAL FUNDS COMPANIES FOR LIKE SERVICES. Lipper, Inc., an analytical service that is not affiliated with the Adviser, compared the fees charged to the Funds with fees charged to other investment companies for similar services by other investment advisers. Lipper's analysis included the Funds' ranking with respect to the proposed management fees relative to the Lipper group median at the approximate current asset levels of the Funds.(5) Effective Lipper Management Group Fund Fee(6) Median Rank - ------------------------------------------------------------------------------- California Portfolio 0.450 0.485 4/10 Insured California Portfolio 0.450 0.548 1/5 National Portfolio 0.450 0.613 2/13 Insured National Portfolio 0.450 0.500 1/7 New York Portfolio(7) 0.450 0.500 3/11 Lipper also analyzed the expense ratio of the Funds in comparison to its Lipper Expense Group(8) and Lipper Expense Universe(9). Lipper describes a Lipper Expense Group as a representative sample of comparable funds, consisting of all (4) The fees charged to the fund include a 0.10% fee for administrative services provided by the Adviser or its affiliates. (5) It should be noted that "effective management fee" is calculated by Lipper using each Fund's contractual management fee rate at a hypothetical asset level. The hypothetical asset level is based on the combined net assets of all classes of each Fund, rounded up to the next $25 million. Lipper's total expense ratio information is based on the most recent annual report except as otherwise noted. A ranking of "1" means that the AllianceBernstein Fund has the lowest effective fee rate in the Lipper peer group. (6) It should be noted that the "effective management fee" rate for the Funds does not reflect the payments by the Funds to the Adviser for certain clerical, legal, accounting, administrative and other services. The dollar amount and basis point impact of such payments on the Funds is discussed in Section I. (7) The number of funds used in Lipper's group ranking for management fees is one less than the number of funds used in Lipper's group ranking for total expenses. According to Lipper, the excluded fund's contractual management fee cannot be computed because of its breakpoint gross income component. (8) Lipper uses the following criteria in screening funds to be included in each Fund's Expense Group: fund type, investment classification/objective, load type and similar 12b-1/non-12b-1 service fees, asset (size) comparability, and expense components and attributes. An Expense Group will typically consist of seven to twenty funds. (9) Except for asset (size) comparability and load type, Lipper uses the same criteria for selecting an Expense Group when selecting an Expense Universe. Unlike an Expense Group, an Expense Universe allows for the same adviser to be represented by more than just one fund. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 121 funds in the investment classification/objective with a similar load type as the subject Fund. The Lipper Expense Universe is a broader collection of. The results of that analysis are set forth below: Lipper Lipper Lipper Lipper Expense Universe Universe Group Group Fund Ratio(10) Median Rank Median Rank - ------------------------------------------------------------------------------- California Portfolio 0.778 0.835 12/31 0.768 6/10 Insured California Portfolio 0.996 0.856 6/6 0.862 5/5 National Portfolio 0.680 0.875 5/74 0.884 1/13 Insured National Portfolio 1.028 0.930 12/15 0.982 6/7 New York Portfolio(11) 0.590 0.859 2/29 0.863 1/12 Based on this analysis, except for National Portfolio and New York Portfolio, which have a more favorable ranking for total expense ratio compared to management fees, the Funds have a more favorable ranking on a management fee basis than they do on a total expense ratio basis. This has resulted in a variety of efforts by the Adviser to lower non-management expenses. III. COSTS TO THE ADVISER AND ITS AFFILIATES OF SUPPLYING SERVICES PURSUANT TO THE MANAGEMENT FEE ARRANGEMENT, EXCLUDING ANY INTRA-CORPORATE PROFIT. The profitability information for the Funds prepared by the Adviser for the Board of Directors was reviewed by the Senior Officer. An independent consultant is working with the Adviser's personnel on a new system to produce profitability information at the Fund level which will reflect the Adviser's management reporting approach. It is possible that future Fund profitability information may differ from previously reviewed information due to changes in methodologies and allocations. See Section IV for additional discussion. IV. PROFIT MARGINS OF THE ADVISER AND ITS AFFILIATES FOR SUPPLYING SUCH SERVICES. The Adviser's profitability from providing investment advisory services to the Funds decreased during calendar 2004 relative to 2003 primarily as a result of the reduction in the advisory fee schedule implemented early in 2004. In addition to the Adviser's direct profits from managing the Funds, certain of the Adviser's affiliates have business relationships with the Funds and may earn a profit from providing other services to the Funds. The courts have referred to this type of business opportunity as "fall-out benefits" to the Adviser and indicated that they should be factored into the evaluation of the total relationship between the Funds and the Adviser. Neither case law nor common business practice precludes the Adviser's affiliates from earning a reasonable profit on this type (10) Most recent fiscal year end Class A share expense ratio. (11) See footnote 7 on page 121. 122 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND of relationship. These affiliates provide transfer agent and distribution services to the Funds and receive transfer agent fees, Rule 12b-1 payments, front-end sales loads and contingent deferred sales charges ("CDSC"). Additional information regarding distribution related fees can be found in the prospectus of the Funds. The Adviser's affiliate, AllianceBernstein Investment Research and Management, Inc. ("ABIRM"), is the Funds' principal underwriter. ABIRM and the Adviser have disclosed in the Funds prospectus that they may make payments(12) from their own resources, in addition to resources derived from sales loads and Rule 12b-1 fees, to firms that sell shares of the Funds. In 2004, ABIRM paid approximately 0.04% of the average monthly assets of the AllianceBernstein Mutual Funds for distribution services and educational support. For 2005, it is anticipated, ABIRM will pay approximately 0.04% of the average monthly assets of each of the Funds for such purposes. After payments to third party intermediaries, ABIRM retained the following amount in Class A front-end load sales charge from sales of the Funds' shares in the Funds' most recent fiscal year. Fund Amount Received - ------------------------------------------------------------------------------- California Portfolio $ 39,251 Insured California Portfolio $ 4,636 National Portfolio $ 28,633 Insured National Portfolio $ 5,256 New York Portfolio $ 25,534 ABIRM received the amounts set forth below in Rule 12b-1 fees for the Funds during the Funds most recent fiscal year. A significant percentage of such amounts were paid out to third party intermediaries by ABIRM. 12b-1Fee Fund Received CDSC Received - ------------------------------------------------------------------------------- California Portfolio $ 5,426,523 $ 51,798 Insured California Portfolio $ 805,741 $ 191,927 National Portfolio $ 1,064,679 $ 241,418 Insured National Portfolio $ 824,338 $ 183,133 New York Portfolio $ 2,941,261 $ 75,292 Fees and reimbursements for out of pocket expenses charged by Alliance Global Investor Services, Inc. ("AGIS"), the affiliated transfer agent, are based on the level of the network account and the class of share held by the account. AGIS also receives a fee per shareholder sub-account for each account maintained by an (12) The total amount paid to the financial intermediary in connection with the sale of shares will generally not exceed the sum of (a) 0.25% of the current year's Fund sales by that firm and (b) 0.10% of the average daily net assets attributable to that firm over the year.

AGIS received the following fees from the Funds in the most recent fiscal year: Fund AGIS Fee - ------------------------------------------------------------------------------- California Portfolio $ 225,239 Insured California Portfolio $ 35,048 National Portfolio $ 256,626 Insured National Portfolio $ 74,396 New York Portfolio $ 184,156 V. POSSIBLE ECONOMIES OF SCALE The Adviser has indicated that the breakpoints in the fee schedule in the Investment Advisory Agreement reflect a sharing of economies of scale to the extent the breakpoints are reached. Based on some of the professional literature that has considered economies of scale in the mutual fund industry it is thought that to the extent economies of scale exist, they may more often exist across a fund family as opposed to a specific fund. This is because the costs incurred by the Adviser, such as investment research or technology for trading or compliance systems can be spread across a greater asset base as the fund family increases in size. It is also possible that as the level of services required to operate a successful investment company has increased over time, and advisory firms have made such investments in their business to provide improved services, there may be a sharing of economies of scale without a reduction in advisory fees. An independent consultant made a presentation to the Board of Directors and the Senior Officer regarding possible economies of scale or scope in the mutual fund industry. Based on the presentation, it was evident that fund management companies benefit from economies of scale. However, due to lack of cost data, researchers had to infer facts about the costs from the behavior of fund expenses; there was a lack of consensus among researchers as to whether economies of scale were being passed on to the shareholders. It is contemplated that additional work will be performed to determine if the benefits of economies of scale or scope are being passed to shareholders by the Adviser. In the meantime, it is clear that to the extent the Funds' assets exceed the initial breakpoint its shareholders benefit from a lower fee rate. VI. NATURE AND QUALITY OF THE ADVISER'S SERVICES INCLUDING THE PERFORMANCE OF THE FUNDS. With assets under management of $516 billion as of June 30, 2005, the Adviser has the investment experience to manage and provide non-investment services (described in Section II) to the Funds. 124 o ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND The information prepared by Lipper showed the 1, 3, 5 and 10 year performance ranking of the Funds(13) relative to its Lipper group and universe for the periods ended May 31, 2005: California Portfolio Group Universe - -------------------------------------------------------------------- 1 year 4/10 11/35 3 year 3/9 8/31 5 year 8/9 24/30 10 year 3/9 6/26 Insured California Portfolio Group Universe - -------------------------------------------------------------------- 1 year 2/5 3/6 3 year 4/5 5/6 5 year 4/5 5/6 10 year 3/5 4/6 National Portfolio Group Universe - -------------------------------------------------------------------- 1 year 2/13 8/80 3 year 7/13 35/74 5 year 8/13 38/68 10 year 6/11 22/53 Insured National Portfolio Group Universe - -------------------------------------------------------------------- 1 year 1/7 1/16 3 year 2/7 2/15 5 year 3/7 4/15 10 year 3/7 4/14 New York Portfolio Group Universe - -------------------------------------------------------------------- 1 year 3/12 6/31 3 year 4/12 8/28 5 year 9/12 20/28 10 year 4/12 7/26 Set forth below are the 1, 3, 5, 10 year and since inception performance returns of the Funds (in bold)(14) versus its benchmarks(15). It should be noted that each Fund has the Lehman Brothers Municipal Bond Index as its benchmark. The Lehman Brothers Municipal Bond Index is a rules-based, market-value-weighted index engineered for the long-term tax-exempt bond market. To be included, bonds must be investment grade and be at least one year from maturity. The index has four main sectors: general obligation bonds, revenue bonds, insured (13) The performance rankings are for the Class A shares of the Funds. (14) The Funds' performance returns are for the Class A shares of the Funds. (15) The Adviser provided Fund and benchmark performance return information for periods through May 31, 2005 in order to maintain consistency with Lipper's performance rankings in the analysis. ALLIANCEBERNSTEIN MUNICIPAL INCOME FUND o 125 bonds and pre-funded bonds. The index represents a national municipal bond index as opposed to a specific state index.

This conclusion in respect of the Funds is based on an evaluation of all of these factors and no single factor was dispositive.
