REPORTS TO STOCKHOLDERS. [UBS GLOBAL ASSET MANAGEMENT LOGO] Insured Municipal Income Fund Inc. Annual Report March 31, 2003 Insured Municipal Income Fund Inc. May 15, 2003 DEAR SHAREHOLDER, We present you with the annual report for Insured Municipal Income Fund Inc. for the fiscal year 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 fiscal year ended March 31, 2003, the Fund's net asset value advanced 10.45%, while its market price increased 10.61%, underperforming its competitors as measured by the Lipper Insured Municipal Debt Funds (Leveraged) Median. For comparison purposes, the Lipper Median's net asset value and market price grew 12.69% and 14.19%, respectively. The Fund lagged its benchmark primarily due to its shorter average duration compared to its peers. (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. The economy didn't move in any clear direction over the period. Initially, it appeared to be on the path to recovery. Newly reported gross domestic product (GDP) for the first quarter of 2002 came in at a strong 5.0%. Second quarter GDP told a very different story, however, as ongoing threats of terrorism, turmoil in the Middle East, falling corporate spending, a weak stock market, and corporate accounting scandals took their toll. The final figure came in at a tepid 1.3%. Although the news improved somewhat during the third quarter--GDP rose to 4.0%--hopes for economic recovery dimmed when fourth quarter 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, continued to weigh heavily on the forces driving economic growth. This was ultimately reflected in the advance GDP figure for first quarter 2003, which came in at 1.6%. ---------------------------------- INSURED 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: June 8, 1993 NYSESYMBOL: PIF DIVIDEND PAYMENTS: Monthly. ---------------------------------- ================================================================================ 1 Insured Municipal Income Fund Inc. 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 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 ONE-YEAR PERIOD? A. The bond market performed well, although there were periods of volatility due to uncertainty engendered by the economy and the situation in Iraq. Looking at the period as a whole, yields fell and 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. WHILE THE FUND GENERATED STRONG ABSOLUTE RETURNS, IT LAGGED ITS BENCHMARK DURING THE PERIOD. WHAT WAS THE PRIMARY REASON FOR THIS? A. As we explained in our last report to shareholders, the Fund's performance has been affected by our attempt to minimize the realization of capital gains. This has become increasingly difficult to do, because nearly every security in the portfolio has appreciated due to the strong performance of the municipal market. One way to avoid capital gains is to hold on to positions in the portfolio. However, in doing so, many of the securities in the Fund's portfolio have "aged" to the point where they have short maturities. Given the falling interest rate environment, the Fund's shorter duration caused it to underperform its peers. Another result of our focus on avoiding the realization of capital gains is that it limits our flexibility to invest in longer-term securities that offer compelling yield and quality characteristics. Therefore, during the period we worked to prudently eliminate certain holdings with shorter durations in an effort to extend the Fund's duration and enhance its portfolio. One example was our sale of Louisville & Jefferson County Metropolitan Sewer District Sewer & Drain System bonds ================================================================================ 2 Insured Municipal Income Fund Inc. that mature in 2004. This security offered a low yield and modest capital gain, making it an appropriate candidate to eliminate from the portfolio. Q. WHEN PURCHASING NEW BONDS FOR THE PORTFOLIO, ARE YOU TARGETING A SPECIFIC DURATION RANGE AND YIELD? A. Yes, we are targeting 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). It is also important to point out that we're diversifying the portfolio by investing a portion of the portfolio in AAA-rated uninsured bonds. By prospectus, we can invest up to 20% of the Fund's portfolio in these issues. U.S. government securities back many of the uninsured securities we're holding in the portfolio, and we believe they offer superior quality versus certain insured bonds. Q. CAN YOU SHARE SOME EXAMPLES OF SECTORS YOU'RE EMPHASIZING AND SPECIFIC SECURITIES YOU ADDED TO THE PORTFOLIO DURING THE PERIOD? A. We like the fundamentals offered by essential service revenue bonds, including revenue-producing utilities, and, 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 are also drawn to 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 is a vital component of our economy. An example of a holding in this area is St. Louis Airport bonds. 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 impact of 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 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. Rather, we intend to focus on ================================================================================ 3 Insured Municipal Income Fund Inc. essential service revenue bonds and lengthening the Fund's duration to bring it to a market-neutral position. 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 ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Insured Municipal Income Fund Inc. (the "Fund") was incorporated in Maryland on February 18, 1993, 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 the Fund's 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 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 ================================================================================ 20 Insured Municipal Income Fund Inc. Notes to Financial Statements 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 $313,848, representing $364,468 for investment advisory and administration fees less fee waivers of $50,620. For the year ended March 31, 2003, UBS Global AM voluntarily waived $590,524 in investment advisory and administration fees from the Fund. COMMON STOCK There are 199,997,000 shares of $0.001 par value common stock authorized and 20,628,363 common shares outstanding at March 31, 2003. AUCTION PREFERRED SHARES The Fund has issued 800 shares of Auction Preferred Shares Series A, 800 shares of Auction Preferred Shares Series B, 800 shares of Auction Preferred Shares Series C and 600 shares of Auction Preferred Shares Series D, 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 7 days for APS Series A, 28 days for APS Series B, 90 days for APS Series C and 7 days for APS Series D. Dividend rates ranged from 0.90% to 1.85% for the year 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 common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of APS at liquidation value. ================================================================================ 21 Insured Municipal Income Fund Inc. Notes to Financial Statements 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 (from investments having an excess value over cost) .................................... $ 25,002,282 Gross depreciation (from investments having an excess of cost over value) ................................. (6,926,195) ------------ Net unrealized appreciation of investments ...................... $ 18,076,087 ============ For the year ended March 31, 2003, total aggregate purchases and sales of portfolio securities, excluding short-term securities, were $121,668,337 and $108,707,008, 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, 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 years ended March 31, 2003 and March 31, 2002 were as follows: Distributions paid from: 2003 2002 ----------- ----------- Tax-exempt income .................................... $19,306,799 $18,703,218 ----------- ----------- At March 31, 2003, the components of accumulated earnings on a tax basis were as follows: Undistributed tax-exempt income ...................... $ 2,782,917 Undistributed long-term capital gains ................ 1,566,387 ----------- Accumulated earnings ................................. 4,349,304 Net unrealized appreciation of investments ........... 18,076,087 ----------- Total accumulated earnings ........................... $22,425,391 =========== ================================================================================ 22 Insured Municipal Income Fund Inc.

Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of investments owned as of March 31, 2003, by correspondence with the custodian and brokers.

GENERAL INFORMATION (UNAUDITED) THE FUND Insured Municipal Income Fund Inc. (the "Fund") is a diversified, closed-end management investment company whose shares trade on the New YorkStock Exchange ("NYSE").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 Fund's investment advisor and administrator is UBS Global Asset Management (US) Inc. ("UBS Global AM"), an indirect wholly owned asset management subsidiary of UBS AG, which has over $73.0 billion in assets under management as of April 30, 2003. SHAREHOLDER INFORMATION The Fund's NYSE trading symbol is "PIF." Comparative net asset value and market price information about the Fund is published weekly in THE WALLSTREET JOURNAL, THE NEW YORK TIMES and BARRON'S, as well as in numerous other publications. 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 ================================================================================ 26 Insured Municipal Income Fund Inc. GENERAL INFORMATION (UNAUDITED) (CONTINUED) DIVIDEND REINVESTMENT PLAN (CONCLUDED) 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 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. ================================================================================ 27 Insured Municipal Income Fund Inc.
