Reports to Stockholders. [LOGO] UBS Global Asset Management Investment Grade Municipal Income Fund Inc. Semiannual Report March 31, 2003 Investment Grade Municipal Income Fund Inc. May 15, 2003 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 Dear Shareholder, We present you with the semiannual report for Investment Grade Municipal Income Fund Inc. for the six months ended March 31, 2003. An Interview with Portfolio Manager William Veronda Q. How did the Fund perform during the period relative to its peers? A. For the six months ended March 31, 2003, the Fund's net asset value return grew 2.77% and its market price return declined 1.39%. The Lipper General Municipal Debt Funds (Leveraged) Median's net asset value rose 0.36% and its market price declined 0.64%, respectively. (For more performance information, please refer to "Performance At A Glance" on page 5). Q. Can you describe the economic environment during the period? A. As the reporting period began in October 2002, the economy appeared to be on the road to recovery. Third quarter's gross domestic product (GDP) figure had just been announced at 4.0%, a move in the right direction after second quarter's anemic 1.3% growth rate. However, hopes for economic recovery dimmed when fourth quarter's GDP came in at 1.4%. By the time the review period wound down in March, little about this economic picture had changed. Fears concerning a potential war with Iraq were replaced by fears over the longevity and cost of the war after it began. It was also clear that other factors, including the heightened threat of terrorism and saber-rattling in North Korea were continuing to weigh heavily on the forces that drive economic growth. This was ultimately reflected in the advance GDP figure for first quarter 2003, which came in at 1.6%. Q. How did the Federal Reserve Board (the "Fed") react to the weakening economy? A. In November 2002, the Fed acknowledged that the economy appeared to have hit a "soft spot". Thus, after holding interest rates steady during the first ten months of 2002, the Fed, at its November meeting, moved to lower the - -------------------------------------------------------------------------------- 1 Investment Grade Municipal Income Fund Inc. federal funds rate one half of a percentage point to 1.25%--a 41-year low. Since that time, the Fed has held rates steady--most recently at its May 6, 2003 meeting. Q. How did the bond market perform during the six-month period? A. The bond market performed well, although there were periods of volatility due to the uncertainty engendered by the economy and the situation in Iraq. Looking at the period as a whole, bond prices rose as investors were drawn to the relative safety offered by fixed income securities, including municipal bonds. Q. During the last several years, interest rates have substantially declined. Has this affected the Fund? A. Yes, it has. A number of issuers have chosen to call, or buy back, their bonds before their stated maturity dates. By doing so, the issuers can then issue new securities at today's lower rates, and thus cut their borrowing costs. We are using the proceeds we receive from these involuntary sales to purchase bonds offering lower coupons. Because of this trend, however, we are taking special care to thoroughly investigate any call provisions in the bonds we are considering for the Fund. Q. The Fund's NAV returns were better than the average return of its peers. What were some of the factors that led to these results? A. The Fund benefited from our strategy to reposition the portfolio from one with a shorter-than-average duration to one that was more neutral to its peer group. As we explained in the last report to shareholders, we've been emphasizing bonds with longer durations, typically those with maturities that more accurately reflect the municipal market as a whole. This strategy has increased our flexibility to purchase what we believe are attractively structured and priced municipal securities. Q. When purchasing new bonds for the portfolio, are you targeting a specific duration range and yield? A. Yes, we are emphasizing bonds with approximately a 10-year call and a maturity in the 15- to 20-year range. We believe these issues allow us to maximize yield relative to market volatility. Additionally, we're looking for bonds that offer a yield premium of 50 to 100 basis points versus what is currently available in the marketplace (a basis point is 1/100 of a percentage point). - -------------------------------------------------------------------------------- 2 Investment Grade Municipal Income Fund Inc. Q. Are there any areas of the investment grade municipal market that you're emphasizing? A. We like the fundamentals offered by essential service revenue bonds, including revenue-producing utilities--in particular, select electric power revenue bonds. We're seeing a rebound in this area due to a reversal in the deregulation that led to severe problems in states such as California. We're also drawn to select airport revenue bonds. While the airline industry is extremely weak, we believe many airport bonds offer compelling opportunities, since the need for airfreight and transportation will continue to be a vital component of our economy. Q. Can you share some examples of specific securities that were added to, or eliminated from, the portfolio during the period? A. One example of the type of security we're emphasizing is Gainesville Utilities Systems bonds. This is a revenue-generating security that offers a yield of 4.54%, with a 17-year maturity and a call date of 10 years. Based on our extensive credit analysis, we also added Augustana College bonds to the portfolio. Augustana, founded in 1860, is a private liberal arts and sciences college in Illinois, with a student population of 2,200. We were drawn to its strong fundamentals, which include a substantial endowment that equals one half of its outstanding debt. Its bonds offer a healthy 5.58% yield and mature in 9 years. Conversely, we eliminated our position in New York City Transitional Financing Authority Revenue bonds. We were concerned about the fundamentals of this security, based on the weakness in the city's economy, and, in particular, because of the smaller tax revenues coming from the city's financial services organizations. While these bonds are still investment grade, we chose to proactively exit the position based on our credit concerns. Q. What is your outlook for the economy, and how do you anticipate positioning the Fund's portfolio going forward? A. The economy clearly failed to gain any momentum during the period, and we believe it is likely to expand only modestly in the coming months. In terms of interest rates, the outlook remains cloudy at best, due to the uncertainties surrounding the war in Iraq and its effect on economic growth. On a strategy level, the mounting state budget deficits have drawn our attention. Numerous states have seen their budget surpluses dry up and become - -------------------------------------------------------------------------------- 3 Investment Grade Municipal Income Fund Inc. substantial deficits. In fact, over 90% of the states are now experiencing shortfalls, with a record $80 billion nationwide deficit projected for fiscal year 2004 (which begins on July 1, 2003). In many cases, states have been reluctant to make the necessary spending cuts or to implement tax increases necessary to bring their budgets in line. Because of this, we will continue to avoid state credits that do not meet our stringent quality requirements. Finally, given the uncertain interest rate environment, we intend to keep the Fund's duration neutral to the benchmark. In summary, we'll seek to add value through careful attention to coupon, call, maturity structure and credit analysis. Our ultimate objective in managing your investments is to help you successfully meet your financial goals. We thank you for your continued support and welcome any comments or questions you may have.

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. 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 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. 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 Board determines that this does not represent fair value. 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 an accrual basis. Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments. 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 performance 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 - -------------------------------------------------------------------------------- 17 Investment Grade Municipal Income Fund Inc. Notes to Financial Statements (unaudited) 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 the Fund. UBS Global AM is an indirect wholly owned asset management subsidiary of UBS AG, an internationally diversified organization with headquarters in Zurich, Switzerland and operations in many areas of the financial services 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. At March 31, 2003, the Fund owed UBS Global AM $163,192, representing $189,513 for investment advisory and administration fees less amounts due for fee waivers of $26,321. For the six months ended March 31, 2003, UBS Global AM voluntarily waived $153,951 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, 2003. Auction Preferred Shares The Fund has issued 800 shares of Auction Preferred Shares Series A and 800 shares of Auction Preferred Shares Series B, which are referred to herein collectively as the "APS." 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 28 days for APS Series A and 90 days for APS Series B. Dividend rates ranged from 0.953% to 1.850% for the six months ended March 31, 2003. 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 - -------------------------------------------------------------------------------- 18 Investment Grade Municipal Income Fund Inc. Notes to Financial Statements (unaudited) 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 auction preferred shares will vote separately as a class on certain matters, as required by law. The holders of the auction preferred shares have the right to elect two directors of the Fund. The redemption of the Fund's auction preferred shares 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. Federal Tax Status For federal income tax purposes, at March 31, 2003, the components of net unrealized appreciation of investments were as follows: Gross appreciation (investments having an excess of value over cost) $10,409,134 - ------------------------------------------------------------------------------------- Gross depreciation (investments having an excess of cost over value) (360,812) - ------------------------------------------------------------------------------------- Net unrealized appreciation of investments $10,048,322 ===================================================================================== For the six months ended March 31, 2003, total aggregate purchases and sales of portfolio securities, excluding short-term securities, were $71,605,209 and $69,518,361, 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, 2002 was as follows: Distributions paid from: 2002 ==================================================== Tax-exempt income $10,887,019 - ---------------------------------------------------- Net long-term realized capital gains 436,163 - ---------------------------------------------------- Total distributions paid $11,323,182 ==================================================== Total distributions paid differ from the statement of changes in net assets applicable to common shareholders because for tax purposes dividends are recognized when actually paid. 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 for the Fund after the Fund's fiscal year end, at September 30, 2003. - -------------------------------------------------------------------------------- 19 Investment Grade Municipal Income Fund Inc.

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 PaineWebber 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 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 - -------------------------------------------------------------------------------- 22 Investment Grade Municipal Income Fund Inc. General Information (unaudited) (concluded) Dividend Reinvestment Plan (concluded) 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. - -------------------------------------------------------------------------------- 23 (This page has been left blank intentionally.)
