[UBS GLOBAL ASSET MANAGEMENT LOGO] INSURED MUNICIPAL INCOME FUND INC. ANNUAL REPORT MARCH 31, 2005 INSURED MUNICIPAL INCOME FUND INC. May 26, 2005 DEAR SHAREHOLDER, We present you with the annual report for Insured Municipal Income Fund Inc. (the "Fund") for the fiscal year ended March 31, 2005. Below you will find information regarding the Fund's performance and an interview with the Fund's portfolio manager. After these sections, you will find additional information regarding investment policy changes. These changes will permit greater flexibility in investing a portion of the Fund's investments. These changes do not modify the Fund's policy to invest at least 80% of its net assets in insured municipal obligations under normal circumstances. PERFORMANCE Over the 12-month period, the Fund's net asset value return was 2.48%. On a market price basis, the Fund declined 6.55%. Over the same period, the Fund's peer group, the Lipper Insured Municipal Debt Funds (Leveraged) median's net asset value and market price returns were 3.03% and -3.92%, respectively. Finally, the Fund's benchmark, the Lehman Brothers U.S. Municipal Bond Index (the "Index"), returned 2.67%. (For more performance information, please refer to "Performance At A Glance" on page 7). As the market price for both the Fund and the median of its peer group moved down while net asset values appreciated, discounts widened during the period. The Fund continued to use leverage during the period, which was 40% of total assets as of March 31, 2005. Leverage can magnify returns on the upside and on the downside, and the degree of leverage used 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 DURING THE FISCAL YEAR? A. The US economy faced a number of challenges during the reporting period, including record high oil prices, rising interest rates, a mixed job market, uncertainty surrounding the presidential election and geopolitical events. Despite these issues, the economy proved to be surprisingly resilient. Following a 3.3% [SIDENOTE] 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 NYSE SYMBOL: PIF DIVIDEND PAYMENTS: Monthly 1 gain in the second quarter of 2004, gross domestic product (GDP) growth was a robust 4.0% in the third quarter and 3.8% in the fourth quarter. Preliminary estimates for first quarter 2005 GDP growth were 3.5% Q. HOW DID THE FED REACT TO THESE ECONOMIC CONDITIONS? A. Given the strength of the economy, it became increasingly clear that the Federal Reserve Board's (the "Fed") accommodative monetary policy would change and it would begin to raise interest rates in an attempt to ward off a potential increase in inflation. As expected, the Fed raised the federal funds rate (or "fed funds" rate)--the rate that banks charge one another for funds they borrow on an overnight basis--from 1.00% in June 2003 to 1.25% at the end of June 2004. This was the first rate hike in four years. The Fed raised rates in 0.25% increments on six more occasions over the fiscal year, bringing the fed funds rate to 2.75% by the end of March 2005. Toward the end of the period, the Fed appeared to become increasingly concerned about inflation. Coinciding with the March rate hike, the Fed continued to say it expected to raise rates at a "measured" pace. However, it also said that inflationary pressures "have picked up in recent months and pricing power is more evident," whereas in February it stated that inflation was "well contained." Many market participants believed this telegraphed the potential for rate hikes larger than 0.25% in the future. The Fed did indeed raise rates again after the period closed, bringing the rate to 3.0%. Q: HOW DID YOU POSITION THE FUND'S PORTFOLIO DURING THE FISCAL YEAR? A: Given our expectation that yields would rise in concert with the Fed's tightening cycle, the Fund's duration was shorter than the benchmark during the fiscal year. While this led to mixed results over the period, our yield curve positioning generally enhanced results over the reporting period. We expected the yield curve to flatten, whereby the gap between short- and long-term yields narrows, and so we maintained a barbell strategy for the portfolio. In doing so, we held relative overweights in both short-term and longer-term securities. In the second half of the fiscal year, this was coupled with an underweight in the 2- to 8-year portion of the curve. This positioning proved to be beneficial for results as longer-term securities performed well and the 2- to 8-year segment of the yield curve lagged the overall market. During the period, we received approval from the Fund's Board of Directors to invest up to 20% of the portfolio in non-insured municipal obligations that are rated at least BBB by S&P or Baa by Moody's. We believe that this will bring the Fund into closer alignment with its peer group, and expect it will provide us with the flexibility to invest in securities that offer the opportunity to generate incremental income. More details regarding these changes are provided on page 6. 2 Q: COULD YOU DESCRIBE SOME NEW PURCHASES MADE FOR THE FUND OVER THE PERIOD? A: In the fourth quarter of 2004, we added New Jersey Economic Development Authority bonds, which have a 5.0% coupon and mature in 2009. We found this issue, secured by the pledge of cigarette taxes in the state, to be attractively priced. While New Jersey faces a significant deficit in 2005, we believe the bonds are well-secured given the state's high per capita income and diversified economy. A good example of how we employed the barbell strategy for the portfolio was our addition of both Sacramento Sanitation District bonds, offering a 5.0% coupon and maturing in 2035, and San Diego California Unified School District bonds, offering a 5.0% coupon and maturing in 2029. We found these securities to be attractively valued, and they benefited as the yield curve flattened. We subsequently sold these holdings, as we felt they became richly valued. Q: WHICH AREAS DID YOU EMPHASIZE FROM A REGIONAL STANDPOINT? A: We focused on states that we believed were exhibiting improved fiscal health and whose municipal bonds were attractively valued. For example, throughout the period we emphasized securities from the California tax-exempt market. Following its financial crisis in 2003, California's fiscal situation has seen considerable improvements. Our overweight position in California enhanced results as the state's bonds continued to outperform the overall market during the year. Given this appreciation, we believe California municipal securities are now fairly valued given their underlying fundamental risks. Q: WHAT ARE YOUR VIEWS OF THE HEALTHCARE AND TOBACCO SECTORS? A: Given an environment of declining government reimbursements, we were negative on the healthcare sector in general. However, as the period progressed we selectively purchased certain hospital bonds that we believed offered yields that fairly compensated investors for their risks. This strategy proved beneficial for the Fund. We continued to avoid tobacco settlement bonds, as we maintained our negative long-term outlook for the sector. This positioning detracted from results over the period, as these more speculative tobacco bonds performed well. Q: WHICH SECTORS DID YOU EMPHASIZE OVER THE FISCAL YEAR? A: The Fund's portfolio is highly diversified and is exposed to a wide variety of sectors. Having said that, one area that we found attractive was the airport sector. Unlike the troubled airline industry, airports have performed well as the economy has improved. Both business and consumer flight trends have surpassed their pre-September 11, 2001 levels. 3 An example of a holding in this area was Metropolitan Washington (DC) Airports Authority bonds, which offer a 5.25% coupon, mature in 2016, and are also subject to the alternative minimum tax (AMT). Although the Fund has always been able to invest in AMT bonds, historically it has not done so. During the fiscal year, we informed the Board of our intention to begin purchasing these bonds where appropriate. As with the added flexibility to invest in BBB/Baa bonds, investing in AMT bonds also brings the Fund into closer alignment with its peer group. This should provide us the opportunity to invest in securities that generate additional incremental income. Q: CAN YOU EXPLAIN HOW THE USE OF LEVERAGE CAN AFFECT THE FUND'S PORTFOLIO? A: As of March 31, 2005, 40% of the Fund was leveraged. This means that the Fund had "borrowed" money by issuing preferred shares. While leverage can increase the Fund's short-term volatility, we believe it better positions us to seek our goal of generating high current income that is exempt from federal income tax, consistent with the preservation of capital. Q. HOW WAS THE FUND POSITIONED AT THE END OF THE FISCAL YEAR? A. At this point, it appears US economic growth will be sustainable, despite the increase in oil prices. In particular, consumer spending has remained solid, and corporate capital expenditures appear to be improving. In terms of the Fund's portfolio, we expect to remain defensively positioned and to continue to employ a barbell positioning structure. We will continue to look for opportunities where individual securities appear to be structurally mispriced, and focus on states with improving balance sheets whose bonds are attractively valued. 4 We thank you for your continued support and welcome any comments or questions you may have.

One of the Fund's investment policies has permitted investment of up to 20% of its portfolio in non-insured municipal obligations meeting certain criteria, including (i) non-insured municipal obligations that are rated at least AAA by Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), Aaa by Moody's Investors Services, Inc. ("Moody's"), or have received an equivalent rating from another nationally recognized statistical rating organization (NRSRO), and (ii) non-insured municipal obligations that are guaranteed by an entity rated at least AAA by S&P, Aaa by Moody's, or an equivalent rating from another NRSRO. The Fund's Board of Directors has approved a change that will permit the Fund to invest up to 20% of its portfolio in non-insured municipal obligations that are rated at least BBB by S&P, Baa by Moody's, or an equivalent rating from another NRSRO, or that are guaranteed by an entity rated at least BBB by S&P, Baa by Moody's, or an equivalent rating from another NRSRO. The investment policy has also been revised to provide that all non-insured municipal obligations invested in by the Fund be rated at least BBB by S&P, Baa by Moody's, or the equivalent rating by another NRSRO. ("AAA" or "Aaa" is considered the highest rating category, while "BBB" or "Baa" is considered below the highest category but still investment grade.) The revised investment policies are expected to become effective on or after June 1, 2005. As a result, the Fund's 80% investment policy and 20% investment policy would be revised to read as follows: Under normal circumstances, the Fund invests at least 80% of its net assets in Insured Municipal Obligations, the income from which is exempt from regular federal income tax. "Insured Municipal Obligations" are Municipal Obligations that are insured as to the timely payment of both principal and interest by an entity, that, at the time of investment, has a claims-paying ability rated Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO. The Fund may invest up to 20% of its net assets in Municipal Obligations that are not insured but that are, at the time of investment, (1) backed by an escrow or trust account containing sufficient US government or US government agency securities to ensure the timely payment of principal and interest; (2) guaranteed as to timely payment of principal and interest by an entity which has a credit rating of Baa by Moody's, BBB by S&P or an equivalent rating by another NRSRO; or (3) not insured, guaranteed or backed by escrows but rated at least Baa by Moody's, BBB by S&P or an equivalent rating by another NRSRO. The Municipal Obligations described in (1) and (2) above may be unrated if they are determined by the investment advisor to be of comparable quality to Municipal Obligations that have received ratings of at least Baa by Moody's, BBB by S&P, or an equivalent rating by another NRSRO. 6 PERFORMANCE AT A GLANCE (UNAUDITED) AVERAGE ANNUAL TOTAL RETURNS FOR PERIODS ENDED 3/31/05 NET ASSET VALUE RETURNS 6 MONTHS 1 YEAR 5 YEARS 10 YEARS ---------------------------------------------------------------------------------------- Insured Municipal Income Fund Inc. 0.70% 2.48% 6.24% 6.63% Lipper Insured Municipal Debt Funds (Leveraged) median 1.53 3.03 7.92 6.65 MARKET PRICE RETURNS Insured Municipal Income Fund Inc.

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. There can be no assurance that the Fund's investment objective will be achieved. In the normal course of business the Fund may enter into contracts that contain a variety of representations or that provide indemnification for certain liabilities. 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 U.S. generally accepted accounting principles 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 net asset values 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 last reported 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 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 24 recorded on an accrual basis. Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments. FUTURES CONTRACTS--Upon entering into a financial futures contract, the Fund is required to deposit in a segregated account with its custodian, in the name of the futures broker through which the transaction was effected, an amount of cash and/or municipal obligations equal to a certain percentage of the contract amount. This amount is known as the "initial margin". Subsequent payments, known as "variation margin" are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying financial futures contracts. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain or loss until the financial futures contract is closed, at which time the net gain or loss is reclassified to realized gain or loss on futures. Variation margin calls could be substantial in the event of adverse price movements. Using financial futures contracts involves various market risks. If the Fund was unable to liquidate a futures position due to the absence of a liquid secondary market or the imposition of price limits, it could incur substantial losses. The Fund would continue to be subject to market risk with respect to the position. In addition, the Fund would continue to be required to make variation margin payments and might be required to maintain the position being hedged or to maintain cash or securities in a segregated account. Furthermore, certain characteristics of the futures market might increase the risk that movements in the prices of the financial futures contracts might not correlate perfectly with movements in the prices of the investments being hedged, including temporary price distortion. 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 U.S. generally accepted accounting principles. 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. 25 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 applicable to holders of common and auction preferred shares. Prior to August 1, 2004, UBS Global AM had agreed to waive 0.20% of the advisory and administration fee, so that the Fund's effective fee was 0.70% of average weekly net assets applicable to holders of common and auction preferred shares from July 23, 2003 until July 31, 2004. Effective August 1, 2004, the Fund's management fee waiver increased to 0.30%, reducing the effective management fee to 0.60%. This waiver will continue indefinitely unless the Board agrees to any change. At March 31, 2005, the Fund owed UBS Global AM $266,137, which is $399,018 investment advisory and administration fees less fees waived of $132,881. For the year ended March 31, 2005, UBS Global AM waived $1,391,596 in investment advisory and administration fees from the Fund. ADDITIONAL INFORMATION REGARDING COMPENSATION TO AFFILIATE OF A BOARD MEMBER Effective March 1, 2005, Professor Meyer Feldberg accepted the position of senior advisor to Morgan Stanley, resulting in his becoming an interested director of the Fund. The Fund has been informed that Professor Feldberg's role at Morgan Stanley does not involve matters directly affecting any UBS funds. UBS Global AM executes Fund portfolio transactions through Morgan Stanley based on that firm's ability to provide best execution of the transactions. During the year ended March 31, 2005, the Fund purchased and sold certain securities (e.g., fixed income securities) in principal trades with Morgan Stanley having an aggregate value of $102,776,738. Morgan Stanley received compensation for these 26 trades in the form of a "mark-up" or "mark-down" of the price of the securities. Although the precise amount of this compensation is not generally known by UBS Global AM, UBS Global AM believes that under normal circumstances it represents a small portion of the total value of the transactions. 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, 600 shares of auction preferred shares Series D, 600 shares of auction preferred shares Series E and 600 shares of auction preferred shares Series F which are referred to herein collectively as the "APS." All shares of each series of APS have 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 each Series of APS. Dividend rates ranged from 0.750% to 2.600% for the year ended March 31, 2005. 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. Offering expenses of $723,487 were charged to paid-in-capital of the Fund in connection with the offering of APS during the year ended March 31, 2004. PURCHASES AND SALES OF SECURITIES For the year ended March 31, 2005, aggregate purchases and sales of portfolio securities, excluding short-term securities, were $232,355,785 and $234,279,819, respectively. FEDERAL TAX STATUS 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 27 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 years ended March 31, 2005 and March 31, 2004 were as follows: DISTRIBUTIONS PAID FROM: 2005 2004 ----------------------------------------------------------------------------- Tax-exempt income $ 18,116,461 $ 18,738,188 Net long-term capital gains 1,987,330 5,364,503 ----------------------------------------------------------------------------- Total distributions paid $ 20,103,791 $ 24,102,691 ----------------------------------------------------------------------------- At March 31, 2005, the components of accumulated earnings on a tax basis were as follows: Undistributed long-term capital gains $ 1,685,468 Unrealized appreciation of investments and futures 4,423,959 ----------------------------------------------------------------------------- Total accumulated earnings $ 6,109,427 ----------------------------------------------------------------------------- The differences between book-basis and tax-basis unrealized appreciation of investments and futures is attributable to the realization for tax purposes of unrealized gains/losses on certain securities that were marked-to-market and premium amortization adjustments. For federal income tax purposes, the tax cost of investments and the components of net unrealized appreciation of investments at March 31, 2005 were as follows: Tax cost of investments $ 512,517,866 ----------------------------------------------------------------------------- Gross unrealized appreciation $ 6,841,871 Gross unrealized depreciation (2,417,912) ----------------------------------------------------------------------------- Net unrealized appreciation $ 4,423,959 ----------------------------------------------------------------------------- To reflect reclassifications arising from permanent "book/tax" differences for the year ended March 31, 2005, the Fund's undistributed net investment income was increased by $157,289 and accumulated net realized loss from investments and futures was increased by $157,289. These differences are primarily due to reclassification of dividends and premium amortization adjustments. 28 INSURED MUNICIPAL INCOME FUND INC.

We have audited the accompanying statement of assets and liabilities of Insured Municipal Income Fund Inc. (the "Fund"), including the portfolio of investments, as of March 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets applicable to common shareholders for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Insured Municipal Income Fund Inc. at March 31, 2005, the results of its operations for the year then ended, the changes in its net assets applicable to common shareholders for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & young LLP New York, New York May 11, 2005 30 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 York Stock Exchange ("NYSE").

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 had approximately $50.7 billion in assets under management as of March 31, 2005. SHAREHOLDER INFORMATION The Fund's NYSE trading symbol is "PIF."

The Fund's Forms N-Q are available on the SEC's Web site at http://www.sec.gov. The Fund's Forms N-Q may be reviewed and copied at the SEC's Public Reference Room in Washington, D.C. Information on the operation of the SEC's Public Reference Room may be obtained by calling 1-800-SEC-0330. Additionally, you may obtain copies of Forms N-Q from the Fund upon request by calling 1-800-647-1568. 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 31 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 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. 32 (This page has been left blank intentionally) 33 SUPPLEMENTAL INFORMATION (UNAUDITED) BOARDS OF DIRECTORS & OFFICERS The Fund is governed by a Board of Directors which oversees the Fund's operations.

Reproduced below is an excerpt from the charter regarding pre-approval policies and procedures: The [audit ]Committee shall: ... 2. Pre-approve (a) all audit and permissible non-audit services(1) to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund's independent auditors to UBS Global [AM] and any Covered Service Providers, if the engagement relates directly to the operations and financial reporting of the Fund. In carrying out this responsibility, the Committee shall seek periodically from UBS Global [AM] and from the independent auditors a list of such audit and permissible non-audit services that can be expected to be rendered to the Fund, UBS Global [AM] or any Covered Service Providers by the Fund's independent auditors, and an estimate of the fees sought to be paid in connection with such services. The Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to a sub-committee consisting of the Chairperson of the Committee and two other members of the Committee as the Chairperson, from time to time, may determine and appoint, and such sub-committee shall report to the Committee, at its next regularly scheduled meeting after the sub-committee's meeting, its decision(s). From year to year, the Committee shall report to the Board whether this system of pre-approval has been effective and efficient or whether this Charter should be amended to allow for pre-approval pursuant to such policies and procedures as the Committee shall approve, including the delegation of some or all of the Committee's pre-approval responsibilities to other persons (other than UBS Global [AM] or the Fund's officers). ---------- (1) The Committee will not approve non-audit services that the Committee believes may taint the independence of the auditors. Currently, permissible non-audit services include any professional services (including tax services) that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may NOT include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible. Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, UBS Global [AM] and any service providers controlling, controlled by or under common control with UBS Global [AM] that provide ongoing services to the Fund ("Covered Service Providers") constitutes not more than 5% of the total amount of revenues paid to the independent auditors (during the fiscal year in which the permissible non-audit services are provided) by (a) the Fund, (b) its investment adviser and (c) any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit. (e) (2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X: AUDIT-RELATED FEES: There were no amounts that were approved by the audit committee pursuant to the de minimis exception for the fiscal years ended March 31, 2005 and March 31, 2004 on behalf of the registrant.

ALL OTHER FEES: There were no amounts that were approved by the audit committee pursuant to the de minimis exception for the fiscal years ended March 31, 2005 and March 31, 2004 on behalf of the registrant.

(g) For the fiscal years ended March 31, 2005 and March 31, 2004, the aggregate fees billed by E&Y of $135,880 and $436,318, respectively, for non-audit services rendered on behalf of the registrant ("covered"), its investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) and any entity controlling, controlled by, or under common control with the adviser ("non-covered") that provides ongoing services to the registrant for each of the last two fiscal years of the registrant is shown in the table below: 2005 2004 ---------- ---------- Covered Services $ 15,100 $ 25,318 Non-Covered Services 120,780 411,000 (h) The registrant's audit committee was not required to consider whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence. ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS. The registrant has a separately designated standing audit committee (the "Audit Committee") established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended. The Audit Committee is comprised of the following board members: Mr. Armstrong, Mr. Beaubien, Mr. Burt and Mr. White. ITEM 6. SCHEDULE OF INVESTMENTS. Included as part of the report to shareholders filed under Item 1 of this form. ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. The registrant's Board of Directors believes that the voting of proxies on securities held by the registrant is an important element of the overall investment process. As such, the Board has delegated the responsibility to vote such proxies to the registrant's advisor. Following is a summary of the proxy voting policy of the advisor. CORPORATE GOVERNANCE PHILOSOPHY, VOTING GUIDELINES AND POLICY SUMMARY The proxy voting policy of UBS Global AM is based on its belief that voting rights have economic value and must be treated accordingly. Generally, UBS Global AM expects the boards of directors of companies issuing securities held by its clients to act as stewards of the financial assets of the company, to exercise good judgment and practice diligent oversight with the management of the company. While there is no absolute set of rules that determines appropriate corporate governance under all circumstances and no set of rules will guarantee ethical behavior, there are certain benchmarks, which, if substantial progress is made toward, give evidence of good corporate governance. UBS Global AM may delegate to an independent proxy voting and research service the authority to exercise the voting rights associated with certain client holdings. Any such delegation shall be made with the direction that the votes be exercised in accordance with UBS Global AM's proxy voting policy. When UBS Global AM's view of a company's management is favorable, UBS Global AM generally supports current management initiatives. When UBS Global AM's view is that changes to the management structure would probably increase shareholder value, UBS Global AM may not support existing management proposals. In general, UBS Global AM (1) opposes proposals which act to entrench management; (2) believes that boards should be independent of company management and composed of persons with requisite skills, knowledge and experience; (3) opposes structures which impose financial constraints on changes in control; (4) believes remuneration should be commensurate with responsibilities and performance; and (5) believes that appropriate steps should be taken to ensure the independence of auditors. UBS Global AM has implemented procedures designed to identify whether it has a conflict of interest in voting a particular proxy proposal, which may arise as a result of its or its affiliates' client relationships, marketing efforts or banking and broker/dealer activities. To address such conflicts, UBS Global AM has imposed information barriers between it and its affiliates who conduct banking, investment banking and broker/dealer activities and has implemented procedures to prevent business, sales and marketing issues from influencing our proxy votes. Whenever UBS Global AM is aware of a conflict with respect to a particular proxy, its appropriate local corporate governance committee is required to review and agree to the manner in which such proxy is voted. ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES. Form N-CSR disclosure requirement not yet effective with respect to the registrant. ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT COMPANY AND AFFILIATED PURCHASERS.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. The registrant's Board has established a Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee will consider nominees recommended by shareholders if a vacancy occurs among those board members who are not "interested persons" as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended. In order to recommend a nominee, a shareholder should send a letter to the chairperson of the Nominating and Corporate Governance Committee, Richard R. Burt, care of the Secretary of the registrant at UBS Global Asset Management (US) Inc., 51 West 52nd Street, New York, New York 10019-6114, and indicate on the envelope "Nominating and Corporate Governance Committee." The shareholder's letter should state the nominee's name and should include the nominee's resume or curriculum vitae, and must be accompanied by a written consent of the individual to stand for election if nominated for the Board and to serve if elected by shareholders. ITEM 11. CONTROLS AND PROCEDURES. (a) The registrant's principal executive officer and principal financial officer have concluded that the registrant's disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940, as amended) are effective based on their evaluation of these controls and procedures as of a date within 90 days of the filing date of this document. (b) The registrant's principal executive officer and principal financial officer are aware of no changes in the registrant's internal control over financial reporting that occurred during the registrant's most recent fiscal half-year that has materially affected, or is reasonably likely to materially affect, the registrant's internal control over financial reporting.
