[UBS GLOBAL ASSET MANAGEMENT LOGO] Insured Municipal Income Fund Inc. Annual Report March 31, 2004 Insured Municipal Income Fund Inc. May 14, 2004 INSURED MUNICIPAL INCOME FUND INC. Dear Shareholder, Investment Goal: We present you with the annual report for High level of current income Insured Municipal Income Fund Inc. (the exempt from federal "Fund") for the fiscal year ended March 31, income tax, consistent with 2004. preservation of capital. Performance PORTFOLIO MANAGER: For the fiscal year ended March 31, 2004, William Veronda, UBS Global Insured Municipal Income Fund's net Asset Management (US) Inc. asset value return was 4.68%. On a market price basis, the Fund's return was 11.75%. COMMENCEMENT: During the same time period, the Fund's peer June 8, 1993 group, as measured by the Lipper Insured Municipal Debt Funds (Leveraged) median, NYSE SYMBOL: generated net asset value and market PIF price returns of 7.41% and 10.17%, respectively. (For more performance DIVIDEND PAYMENT: information, please refer to "Performance At Monthly A Glance" on page 6). The Fund used leverage during the fiscal period, which was 39.76% 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 DURING THE FISCAL YEAR? A. During the reporting period, the US economy continued to gain momentum, fueled by the ongoing effects of significantly higher military spending, an increase in exports, and robust consumer and business spending. Gross domestic product (GDP) figures confirmed the economy's growth: in the second quarter of 2003, GDP came in at 3.3%, up from 1.4% for the prior quarter. A third quarter 2003 GDP of 8.2% followed; this number, far higher than anticipated, was the sharpest recorded advance of GDP since 1984. Although estimated fourth quarter GDP came in at a lower-than-expected 4.1%, it was, nonetheless, viewed as a solid gain. -------------------------------------------------------------------------------- 1 Insured Municipal Income Fund Inc. While first quarter 2004 GDP figures have not yet been released, the economy appears to be moving forward at a strong pace. With the exception of the job 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 TO 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 view 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 FISCAL YEAR? A. Given the strengthening economy, the overall bond market was surprisingly resilient during the reporting period. However, there were periods of unnerving volatility. Early in the period, yields fell and prices rose as investors were drawn to the relative safety offered by fixed income securities in response to economic uncertainty and geopolitical concerns. Then, beginning in June 2003, bond prices began to fall when a less-than-hoped-for cut in the fed 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 then recouping most of its losses in August and September. As 2004 began, a widely accepted expectation that the economy would continue to expand created a less than promising outlook for fixed income. However, 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" given 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. -------------------------------------------------------------------------------- 2 Insured Municipal Income Fund Inc. 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 much of the period. However, in early 2004, we adjusted the Fund's duration, moving it slightly lower than the benchmark. We felt this cautious approach was warranted, given our belief that rates would rise. This detracted from relative results when yields fell and prices rose during the first quarter of 2004. 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 also held select airport revenue bonds; even though the airline industry itself is weak, the strengthening economy has increased the need for airfreight and transportation. Alternately, we underweighted the hospital sector, as we believe that declining government reimbursements will likely continue and lead to credit deterioration. As we mentioned in our last report to shareholders, we had increased the Fund's exposure to investment grade securities whose ratings are among the very highest-that is, those that have achieved AAA status on their own merits, without the benefit of insurance. This strategy proved beneficial, as it helped us increase the Fund's level of diversification, while giving us the opportunity to invest in a number of compelling opportunities. Q. CAN YOU PROVIDE EXAMPLES OF HOLDINGS THAT WERE ADDED TO THE PORTFOLIO DURING THE PERIOD? A. Late in the fiscal year, we began adding some California revenue credits that are not directly associated with the economic troubles in the state. Examples of specific holdings included Los Angeles Water & Power and Los Angeles County Sanitation District. We are also closely monitoring California's fiscal condition, and are encouraged by the progress that has been made on several fronts. If this trend continues, we expect to selectively increase the Fund's exposure to the state's municipal securities. Q. WERE THERE ANY FACTORS THAT DETRACTED FROM RESULTS DURING THE PERIOD? A. As mentioned previously, during the fiscal year, the Fund's duration was shorter than that of its benchmark, because we did not believe it was prudent to extend duration given the economic expansion and the potential for rising interest rates and falling bond prices. However, this hurt relative results as yields declined and bond prices rose over the fiscal year. -------------------------------------------------------------------------------- 3 Insured Municipal Income Fund Inc. Additionally, 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 Matagorda County Navigation District No. 1 Revenue-Houston Light & Power, which was scheduled to mature in March 2027 and offered a yield of 6.70%. 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 result in an increase in the Fund's short-term volatility, we believe that over the longer-term 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 is 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 (and the Fed has indicated as much). 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. -------------------------------------------------------------------------------- 4 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. 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 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. 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 recorded on -------------------------------------------------------------------------------- 20 Insured Municipal Income Fund Inc. Notes to Financial Statements 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 correlations 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 -------------------------------------------------------------------------------- 21 Insured Municipal Income Fund Inc. Notes to Financial Statements 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. 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. The waiver will continue indefinitely unless the Board agrees to a change. At March 31, 2004, the Fund owed UBS Global AM $315,978 representing $405,741 for investment advisory and administration fees less fee waivers of $89,763. For the year ended March 31, 2004, UBS Global AM waived $867,058 in investment advisory and administration fees from the Fund. 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." (Auction Preferred Shares Series E and Auction Preferred Shares Series F were issued on December 22, 2003). 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 all APS Series. Dividend rates ranged from 0.65% to 2.25% for the year 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. -------------------------------------------------------------------------------- 22 Insured Municipal Income Fund Inc. Notes to Financial Statements Offering costs of $123,487 and sales load of $600,000 were charged to paid-in-capital of the Fund in connection with the offering of Auction Preferred Shares during the year ended March 31, 2004. FEDERAL TAX STATUS For federal income tax purposes, at March 31, 2004, the components of net unrealized appreciation of investments were as follows: Gross appreciation (from investments having an excess value over cost) $14,172,807 ----------------------------------------------------------------------------------------- Gross depreciation (from investments having an excess of cost over value) (1,247,738) ----------------------------------------------------------------------------------------- Net unrealized appreciation of investments and futures $12,925,069 ========================================================================================= For the year ended March 31, 2004, total aggregate purchases and sales of portfolio securities, excluding short-term securities, were $277,065,701 and $166,703,900, 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, 2004 and March 31, 2003 were as follows: DISTRIBUTIONS PAID FROM: 2004 2003 ------------------------------------------------------------ Tax-exempt income $18,738,188 $19,306,799 ------------------------------------------------------------ Net long-term capital gains 5,364,503 - ------------------------------------------------------------ Total distributions paid $24,102,691 $19,306,799 ============================================================ At March 31, 2004, the components of accumulated earnings on a tax basis were as follows: Undistributed tax-exempt income $ 1,073,960 ------------------------------------------------------------------ Undistributed long-term capital gains 1,612,334 ------------------------------------------------------------------ Accumulated capital and other losses - ------------------------------------------------------------------ Unrealized appreciation of investments and futures 12,925,069 ------------------------------------------------------------------ Total accumulated earnings $15,611,363 ================================================================== 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. -------------------------------------------------------------------------------- 23 Insured Municipal Income Fund Inc. Notes to Financial Statements To reflect reclassifications arising from permanent "book/tax" differences for the year ended March 31, 2004, the Fund's undistributed net investment income was decreased by $268,364 and accumulated net realized loss from investments and futures was decreased by $268,364. -------------------------------------------------------------------------------- 24 Insured Municipal Income Fund Inc.

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 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 had approximately $53.1 billion in assets under management as of April 30, 2004. 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 or online on the Fund's Web site www.ubs.com/ubsglobalam-proxy. 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 Wall Street 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 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. -------------------------------------------------------------------------------- 27 Insured Municipal Income Fund Inc. General Information (unaudited) (concluded) DIVIDEND REINVESTMENT PLAN (CONCLUDED) 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. -------------------------------------------------------------------------------- 28 (This page has been left blank intentionally.) -------------------------------------------------------------------------------- 29 Insured Municipal Income Fund Inc.

The charter contains the audit committee's pre- approval policies and procedures. 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(2) 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 [Asset Management (US) Inc. ("UBS Global")] 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 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 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 or the Fund's officers). --------------- (2) 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.

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 and any service providers controlling, controlled by or under common control with UBS Global 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.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS. Form N-CSR disclosure requirement not yet effective with respect to the registrant. ITEM 6. [RESERVED BY SEC FOR FUTURE USE. ] 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 determine 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 interests in voting a particular proxy proposal, which may arise as a result of its or its affiliates' client relationships, marketing efforts or banking, investment 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. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT COMPANY AND AFFILIATED PURCHASERS. Form N-CSR disclosure requirement not yet effective with respect to the registrant. ITEM 9. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. The registrant's Board has established a Nominating Committee. The Nominating 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 Committee, Mr. Meyer Feldberg, 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 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 10. 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.
