May 14, 2004 DEAR SHAREHOLDER, [sidebar] - ---------------------------- INVESTMENT GRADE MUNICIPAL INCOME FUND INC. INVESTMENT GOAL: High level of current income exempt from federal income tax, consistent with preservation of capital. PORTFOLIO MANAGER: William Veronda UBS Global Asset Management (US) Inc. COMMENCEMENT: November 6, 1992 NYSE SYMBOL: PPM DIVIDEND PAYMENTS: Monthly - ---------------------------- [end sidebar] We present you with the semiannual report for Investment Grade Municipal Income Fund Inc. for the six months ended March 31, 2004. PERFORMANCE For the six months ended March 31, 2004, Investment Grade Municipal Income Fund Inc.'s net asset value return was 3.50%. On a market price basis, the Fund's return was 11.12%. Over the same period, the Lipper General Municipal Debt Funds (Leveraged) median's net asset value and market price returns were 5.36% and 9.76%, respectively. (For more performance information, please refer to "Performance At A Glance" on page 5). The Fund used leverage during the period, which was 40.0% of total assets as of March 31, 2004. Leverage can magnify returns on the upside and on the downside, and can create wider dispersions of returns within the Fund's peer group. AN INTERVIEW WITH PORTFOLIO MANAGER WILLIAM VERONDA Q. CAN YOU DESCRIBE THE ECONOMIC ENVIRONMENT? A. During the reporting period, the US economy continued to gain momentum, fueled by the combined effects of ongoing military spending, an increase in exports, and robust consumer and business spending. Gross domestic product (GDP) figures confirmed the economy's growth: following a solid second quarter 2003 GDP figure, third quarter 2003 posted a GDP figure of 8.2%. This number, far higher than anticipated, was the sharpest recorded advance of GDP since 1984. At 4.1%, fourth quarter GDP came in significantly lower, but was still viewed as a solid gain. While first quarter 2004 GDP figures are yet to be released, the economy appears to be moving forward at a strong pace. With the exception of the job - -------------------------------------------------------------------------------- 1 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. market, which has been slow to recover, most areas of the economy are expanding, while overall inflation remains benign. Q. HOW DID THE FEDERAL RESERVE BOARD (THE "FED") REACT IN THE ECONOMIC ENVIRONMENT? A. The Fed held rates steady throughout the period, as it has since it lowered short-term interest rates to 1.00% on June 25, 2003. However, at its May 4, 2004 meeting (held after period end), there was a clear shift in the Fed's stance, when, in its official statement, it noted, "accommodation can be removed at a pace that is likely to be measured." Many viewed this as an indication that the Fed could raise rates as early as its next meeting in June. Q. HOW DID THE BOND MARKET PERFORM DURING THE SIX-MONTH REPORTING PERIOD? A. As the period began, the bond markets had just come off of a period of extreme volatility. Beginning in June 2003, bond prices began to fall when a less-than-hoped-for cut in the federal funds rate, diminishing concerns regarding the potential for deflation, and fears that an improving economy would lead to a less accommodative fiscal policy triggered a selloff. The market declined through July, before stabilizing and recouping most of its losses. As 2004 began, a widely accepted expectation that the economy would continue to expand created a less than promising outlook for fixed income. However, the bond market proved surprisingly resilient. Despite the strong evidence that the economy was expanding, continued weakness in the labor market created a somewhat muddled picture. In February 2004, news that only 21,000 new jobs were created--significantly less than forecasted--gave rise to concerns that consumer confidence could weaken, and, thus, temper economic growth. Bonds rallied on the news. Additionally, periodic "flights to quality" as a result of geopolitical events, including a terrorist attack in Spain and turmoil in the Middle East, bolstered the bond market. The municipal market participated in the broad fixed income rally, and was aided further by a strong demand for municipals. Q. HOW DID YOU POSITION THE FUND'S PORTFOLIO DURING THE REPORTING PERIOD? A. The Fund's duration was held generally in line with that of its benchmark, the Lehman Municipal Bond Index (the "Index"), during the first half of the period. However, in early 2004, we adjusted the Fund's duration, moving it slightly lower than the Index. We felt this cautious approach was warranted, given our belief that rates would increase. This detracted from relative results when yields fell and prices rose during the first quarter of 2004. - -------------------------------------------------------------------------------- 2 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. With regard to sector positioning, we continued to emphasize essential service revenue bonds, including revenue-producing utilities, such as water, sewers and select electric power facilities. We held select airport revenue bonds, because, although the airline industry itself is weak, the strengthening economy has increased the need for airfreight and transportation. We added toll road revenue bonds to the portfolio, including New Jersey Turnpike Authority revenue bonds, and we selectively added several carefully researched BAA-rated securities to the portfolio in order to generate incremental yield. Alternately, we continued to underweight the hospital sector, as we believe declining government reimbursements are likely to continue and, in our opinion, will lead to credit deterioration. Q. CAN YOU PROVIDE SOME EXAMPLES OF NEW HOLDINGS ADDED TO THE PORTFOLIO DURING THE PERIOD? A. Given the equity market revival and the improvements we've seen in certain New York state credits, we added a number of New York City general obligation credits. Late in the fiscal year, we also began to add some California revenue credits that are not directly associated with the economic troubles in the state. An example of one of these holdings is Kaiser Permanente, the country's first health maintenance organization. The firm insures roughly one out of every four Californians, as well as individuals located in other states. We are also closely monitoring California's fiscal condition, and are encouraged by progress that has been made on several fronts. Should this continue, we will look to selectively increase the Fund's exposure to California's municipal securities. Q. WHAT DETRACTED FROM RESULTS DURING THE PERIOD? A. A number of bonds in the Fund's portfolio were "called" or prematurely retired by issuers looking to take advantage of the low interest rate environment-one example was Rhode Island Housing & Mortgage Finance Corp., which was scheduled to mature in April 2027 and offered a yield of 6.50%. Given today's lower rates, it was not possible to replace these holdings with securities that offered comparable yields. Q: WERE THERE ANY OTHER FACTORS THAT AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD? A: In December 2003, the Fund generated a significant amount of new investor assets that were then redeployed using the same positioning strategies previously mentioned. Toward the end of 2003, we increased the Fund's leverage from approximately 33% to 40%. While this could lead to an increase in the Fund's - -------------------------------------------------------------------------------- 3 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. short-term volatility, over time we feel this strategy is consistent with our goal of preservation of capital. It will also help us to moderately extend the Fund's duration. In addition, we believe this increased leveraging will allow the Fund to generate incremental dividend income. Q. HOW DO YOU ANTICIPATE POSITIONING THE FUND'S PORTFOLIO GOING FORWARD? A. Looking ahead, it's our belief that the US economy will continue to expand. Given that interest rates are so low, we believe it is inevitable that they will rise. Based on this outlook, we expect to keep the Fund's duration neutral or slightly lower than that of the Index. In terms of the Fund's portfolio, we are comfortable with its current positioning. Should the economy continue to expand, it will likely serve to improve the fiscal situations in a number of states. If this occurs, we will look to identify select general obligation bonds that we believe offer compelling opportunities.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Investment Grade Municipal Income Fund Inc. (the "Fund") was incorporated in Maryland on August 6, 1992, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended, as a closed-end diversified management investment company. The Fund's investment objective is to achieve a high level of current income that is exempt from federal income tax, consistent with the preservation of capital. In the normal course of business the Fund enters into contracts that contain a variety of representations that provide general indemnification. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires Fund management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies: VALUATION OF INVESTMENTS--The Fund calculates its net asset value based on the current market value, where available, for its portfolio's securities. The Fund normally obtains market values for its securities from independent pricing sources and broker-dealers. Independent pricing sources may use reported last sale prices, current market quotations or valuations from computerized "matrix" systems that derive values based on comparable securities. A matrix system incorporates parameters such as security quality, maturity and coupon, and/or research and evaluations by its staff, including review of broker-dealer market price quotations, if available, in determining the valuation of the portfolio securities. If a market value is not available from an independent pricing source for a particular security, that security is valued at fair value as determined in good faith by or under the direction of the Fund's Board of Directors (the "Board"). The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with sixty days or less remaining to maturity, unless the Fund's Board determines that this does not represent fair value. Securities traded in the over-the-counter ("OTC") market are valued at the last bid price available on the valuation date prior to valuation. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--Investment transactions are recorded on the trade date. Realized gains and losses from investment transactions are calculated using the identified cost method. Interest income is recorded on - -------------------------------------------------------------------------------- 17 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) an accrual basis. Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments. DERIVATIVES--The Fund may use options (both exchange traded and OTC to attempt to enhance income (which would be taxable income) and also may attempt to "hedge" or manage the overall risk of its investments by using options, futures contracts and interest rate protection transactions. The Fund may use derivatives as a substitute for taking a position in an underlying security or other asset and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk. The Fund also may use derivatives to add leverage to the portfolio and/or to hedge against increases in the Fund's costs associated with the dividend payments on preferred stock and auction preferred stock of the Fund. Derivatives are subject to a number of risks, including liquidity risk, interest rate risk, credit risk and leverage risk. They also involve the risk of improper valuation and imperfect correlation with the underlying asset rate index. DIVIDENDS AND DISTRIBUTIONS--The Fund intends to pay monthly dividends to common shareholders at a level rate that over time will result in the distribution of all of the Fund's net investment income remaining after the payment of dividends on any outstanding auction preferred shares. The dividend rate on the common stock is adjusted as necessary to reflect the earnings rate of the Fund. Dividends and distributions to common shareholders are recorded on the ex-dividend date. Dividends to auction preferred shareholders are accrued daily. The amount of dividends from net investment income and distributions from net realized capital gains is determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. CONCENTRATION OF RISK The Fund follows an investment policy of investing primarily in municipal obligations of various states. Economic changes affecting those states and certain of their public bodies and municipalities may affect the ability of the issuers within those states to pay interest on, or repay principal of, municipal obligations held by the Fund. INVESTMENT ADVISOR AND ADMINISTRATOR The Board has approved an investment advisory and administration contract ("Advisory Contract") with UBS Global Asset Management (US) Inc. ("UBS Global AM"), under which UBS Global AM serves as investment advisor and administrator of - -------------------------------------------------------------------------------- 18 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) the Fund. UBS Global AM is an indirect wholly owned asset management subsidiary of UBS AG, an international diversified organization with headquarters in Zurich, Switzerland and operations in many areas of the financial service industry. In accordance with the Advisory Contract, the Fund pays UBS Global AM an investment advisory and administration fee, which is accrued weekly and paid monthly, at the annual rate of 0.90% of the Fund's average weekly net assets. UBS Global AM has agreed to waive 0.20% of the advisory and administration fee, so that the Fund's effective fee is 0.70% of average weekly net assets. This waiver will continue indefinitely unless the Board agrees to any change. At March 31, 2004, the Fund owed UBS Global AM $164,808 representing $211,899 for investment advisory and administration fees less amounts due for fee waivers of $47,091. For the six months ended March 31, 2004, UBS Global AM voluntarily waived $263,341 in investment advisory and administration fees from the Fund. COMMON STOCK There are 199,998,400 shares of $0.001 par value common stock authorized and 10,356,667 common shares outstanding at March 31, 2004. AUCTION PREFERRED SHARES The Fund has issued 800 shares of Auction Preferred Shares Series A, 800 shares of Auction Preferred Shares Series B, and 600 shares of Auction Preferred Shares Series C, which are referred to herein collectively as the "APS." (Auction Preferred Shares Series C were issued on December 22, 2003). All shares of each series of APS have a liquidation preference of $50,000 per share plus an amount equal to accumulated but unpaid dividends upon liquidation. Dividends, which are cumulative, are generally reset every 7 days for APS Series A, APS Series B, and APS Series C. Dividend rates ranged from 0.750% to 2.010% for the six months ended March 31, 2004. The Fund is subject to certain restrictions relating to the APS. Failure to comply with these restrictions could preclude the Fund from declaring any distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of APS at liquidation value. The APS are entitled to one vote per share and, unless otherwise required by law, will vote with holders of common stock as a single class, except that the APS will vote separately as a class on certain matters, as required by law. The holders of the APS have the right to elect two directors of the Fund. The redemption of the Fund's APS is outside of the control of the Fund because it is redeemable upon the occurrence of an event that is not solely within the control of the Fund. - -------------------------------------------------------------------------------- 19 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) Offering costs of $110,332 and sales load of $300,000 were charged to paid-in-capital of the Fund in connection with the offering of APS during the six months ended March 31, 2004. - -------------------------------------------------------------------------------- 20 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) FEDERAL TAX STATUS The components of net unrealized appreciation of investments at March 31, 2004, were as follows: Gross appreciation (investments having an excess of value over cost) $9,926,816 - ------------------------------------------------------------------------------------ Gross depreciation (investments having an excess of cost over value) (257,201) - ------------------------------------------------------------------------------------ Net unrealized appreciation of investments $9,669,615 - ------------------------------------------------------------------------------------ For the six months ended March 31, 2004, total aggregate purchases and sales of portfolio securities, excluding short-term securities, were $95,450,805 and $71,489,800, respectively. The Fund intends to distribute substantially all of its tax-exempt income and any taxable income and to comply with the other requirements of the Internal Revenue Code applicable to regulated investment companies. Accordingly, no provision for federal income taxes is required. In addition, by distributing during each calendar year substantially all of its net investment income, net realized capital gains and certain other amounts, if any, the Fund intends not to be subject to a federal excise tax. The tax character of distributions paid during the fiscal year ended September 30, 2003 was as follows: DISTRIBUTIONS PAID FROM: 2003 ==================================================================================== Tax-exempt income $10,662,658 - ------------------------------------------------------------------------------------ Ordinary income 22,485 - ------------------------------------------------------------------------------------ Net long-term capital gains 2,096,911 - ------------------------------------------------------------------------------------ Total distributions paid $12,782,054 ==================================================================================== The tax character of distributions paid and the components of accumulated earnings (deficit) on a tax basis for the current fiscal year will be calculated after the Fund's fiscal year ending September 30, 2004. - -------------------------------------------------------------------------------- 21 INVESTMENT GRADE MUNICIPAL INCOME FUND INC.

GENERAL INFORMATION (UNAUDITED) INVESTMENT POLICY CHANGE In July 2003, the Fund's Board approved a change in investment policy. The Fund may now invest in securities whose maturities are less than 10 years at the time of purchase. Prior to this change, the Fund had a policy of investing substantially all of its assets in municipal obligations having maturities in excess of 10 years at the time of purchase. PROXY VOTING POLICIES AND PROCEDURES You may obtain a description of the Fund's proxy voting policies and procedures, without charge, upon request by contacting the Fund directly at 1-800-647-1568, online on the Fund's Web site: www.ubs.com/ubsglobalam-proxy, or on the EDGAR Database on the SEC's Web site (http://www.sec.gov). DIVIDEND REINVESTMENT PLAN The Fund's Board has established a Dividend Reinvestment Plan (the "Plan") under which all common shareholders whose shares are registered in their own names, or in the name of UBS Financial Services Inc. or its nominee, will have all dividends and other distributions on their shares of common stock automatically reinvested in additional shares of common stock, unless such common shareholders elect to receive cash. Common shareholders who elect to hold their shares in the name of another broker or nominee should contact such broker or nominee to determine whether, or how, they may participate in the Plan. The ability of such shareholders to participate in the Plan may change if their shares are transferred into the name of another broker or nominee. A common shareholder may elect not to participate in the Plan or may terminate participation in the Plan at any time without penalty, and common shareholders who have previously terminated participation in the Plan may rejoin it at any time. Changes in elections must be made in writing to the Fund's transfer agent and should include the shareholder's name and address as they appear on the share certificate or in the transfer agent's records. An election to terminate participation in the Plan, until such election is changed, will be deemed an election by a common shareholder to take all subsequent distributions in cash. An election will be effective only for distributions declared and having a record date at least ten days after the date on which the election is received. Additional shares of common stock acquired under the Plan will be purchased in the open market, on the NYSE or otherwise, at prices that may be higher or lower than the net asset value per share of the common stock at the time of the purchase. The number of shares of common stock purchased with each dividend will be equal to the result obtained by dividing the amount of the dividend payable to a - -------------------------------------------------------------------------------- 25 INVESTMENT GRADE MUNICIPAL INCOME FUND INC. GENERAL INFORMATION (UNAUDITED) DIVIDEND REINVESTMENT PLAN (CONCLUDED) particular shareholder by the average price per share (including applicable brokerage commissions) that the transfer agent was able to obtain in the open market. The Fund will not issue any new shares of common stock in connection with the Plan. There currently is no charge to participants for reinvesting dividends or other distributions. The transfer agent's fees for handling the reinvestment of distributions will be paid by the Fund. However, each participant pays a pro rata share of brokerage commissions incurred with respect to the transfer agent's open market purchases of common stock in connection with the reinvestment of distributions. The automatic reinvestment of dividends and other distributions in shares of common stock does not relieve participants of any income tax that may be payable on such distributions. Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan with respect to any dividend or other distribution if notice of the change is sent to Plan participants at least 30 days before the record date for such distribution. The Plan also may be amended or terminated by the transfer agent by at least 30 days' written notice to all Plan participants. Additional information regarding the Plan may be obtained from, and all correspondence concerning the Plan should be directed to, the transfer agent at PFPC Inc., P.O. Box 43027, Providence, Rhode Island 02940-3027. For further information regarding the Plan, you may also contact the transfer agent directly at 1-800-331-1710. - -------------------------------------------------------------------------------- 26 DIRECTORS Margo N.
