REPORTS TO STOCKHOLDERS. --------------------------------- [LOGO OF UBS] UBS Global Asset Management FORT DEARBORN INCOME SECURITIES, INC. SEMIANNUAL REPORT MARCH 31, 2006 FORT DEARBORN INCOME SECURITIES, INC. May 15, 2006 DEAR SHAREHOLDER, We present you with the semiannual report for Fort Dearborn Income Securities, Inc. (the "Fund") for the six months ended March 31, 2006. PERFORMANCE Over the six-month period, the Fund declined 1.14% based on net asset value. On a market price basis, the Fund declined 0.78%. Over the same period, the Fund's peer group, the Lipper Corporate Debt Funds BBB-Rated median, posted a net asset value return of 0.09% and declined 0.80% on a market price basis. Finally, the Investment Grade Bond Index (the "Index"), the Fund's benchmark, declined 1.67%. (For more performance information, please refer to "Performance at a Glance" on page 4). Over the period, the Fund did not use leverage. (Neither the Fund's peer group nor the Index use leverage.) Leverage magnifies returns on both the upside and on the downside, creating a wider range of returns. -------------------------------------------------------------------------------- FORT DEARBORN INCOME SECURITIES, INC. INVESTMENT GOAL: Current income consistent with external interest rate conditions and total return. PORTFOLIO MANAGER: Craig Ellinger UBS Global Asset Management (Americas) Inc. COMMENCEMENT: December 19, 1972 NYSE SYMBOL: FDI DIVIDEND PAYMENTS: Quarterly -------------------------------------------------------------------------------- AN INTERVIEW WITH PORTFOLIO MANAGER CRAIG ELLINGER Q. HOW WOULD YOU DESCRIBE THE ECONOMIC ENVIRONMENT DURING THE REPORTING PERIOD? A. Over the past six months, the economy continued to show resilience in the wake of a brutal hurricane season and geopolitical unrest. Overall, unemployment and core inflation both remained low, and consumer confidence, which was somewhat volatile in the early fall, generally continued to rise through the rest of the period. Unemployment, despite large numbers of dislocated workers in the wake of Katrina, improved steadily finishing the period at 4.7%, down from 5.1% at the beginning of the period. Although final data put fourth quarter 2005 GDP growth at 1.7%, advance estimates for the first quarter of 2006 showed a significant rebound, with the economy growing at 4.8%--the highest it has been in nearly three years. -------------------------------------------------------------------------------- 1 FORT DEARBORN INCOME SECURITIES, INC. Q. HOW DID THE FEDERAL RESERVE BOARD (THE "FED") REACT TO THESE ECONOMIC CONDITIONS? A. During the reporting period, the Fed continued its tightening campaign. Through the change in leadership from Alan Greenspan to Ben Bernanke, the fed funds rate (the interest rate banks charge each other for overnight loans) was raised four times during the period, and once more after the period ended, to bring the rate to 5.00%. The market consensus seemed to be that the Fed may be near the end of this current tightening period after having raised rates 16 times since June 2004. While we cannot be certain exactly when the Fed will pause or end its current policy, we believe it is unlikely that during 2006 we will experience the series of uninterrupted rate increases that we saw in 2005. Q. HOW DID THE OVERALL FIXED INCOME MARKETS PERFORM DURING THE REPORTING PERIOD? A. This proved to be a challenging period for fixed income investors. The bond market remained under pressure in response to the Fed's tightening campaign, and an economy that continued to build steam. Across the curve, yields generally rose and, following a brief inversion, the curve ended the period largely flat across maturities. Yields on the 10-year note moved from 4.33% at the beginning of the period to 4.85% at the end. The "carry trade" (borrowing money cheaply and reinvesting it in higher-yielding securities), which sustained many investors for the last two years, has all but disappeared. The bond market, by most measures, was overvalued and therefore unattractive on a price basis. Q. HOW DID YOU MANAGE THE FUND'S PORTFOLIO DURING THE PERIOD? A. In general, we maintained a defensive stance on interest rates and spread product that has been the focus of the Fund's strategy for the past year. (Bonds that offer a yield higher than those of similarly-dated Treasuries are called "spread product." The difference in yields is called the "spread.") Our strategy on spread product was driven by our belief that the risk premium offered for longer-term securities and lower credit quality securities was inadequate. Also, we believed the Fed would continue to raise rates, so we kept the Fund's duration shorter than the benchmark, which helped Fund performance during the reporting period. (A number of funds in our Lipper peer group, however, had even shorter durations, as well as shorter maturities, during the period, both of which detracted from our performance relative to those peers.) We were similarly defensive regarding our exposure to various investment-grade bond sectors. Although the majority of the Fund's assets remain in corporate bonds, the corporate bonds that we owned during the period had significantly shorter maturities than those of the benchmark, another defensive move that helped the Fund considerably. -------------------------------------------------------------------------------- 2 FORT DEARBORN INCOME SECURITIES, INC. In contrast to these defensive strategic themes, we took risk in tactical positions we believed to be appropriately priced. For example, we built a relatively large position in Ford Motor Credit Company (FMCC), Ford's captive finance subsidiary. While not defensive, this position proved to be beneficial and had a positive impact on performance over the past six months. Although the Fund declined during the period, our defensive position helped limit the impact of a challenging market environment. As always, 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 -- MARCH 31, 2006 (UNAUDITED) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Fort Dearborn Income Securities, Inc. ("the Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified closed-end management investment company whose shares trade on the New York Stock Exchange ("NYSE") and the Chicago Stock Exchange ("CHX"). The Fund invests principally in investment grade long-term fixed income debt securities. The Fund's primary objective is to provide shareholders with a stable stream of current income consistent with external interest rate conditions and provide a total return over time that is above what they could receive by investing individually in the investment grade and long-term maturity sectors of the bond market. 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 general 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 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. Securities traded in the over-the-counter ("OTC") market and listed on The Nasdaq Stock Market, Inc. ("NASDAQ") normally are valued at the NASDAQ Official Closing Price. Other OTC securities are valued at the last bid price on the valuation date available prior to valuation. Securities -------------------------------------------------------------------------------- 18 FORT DEARBORN INCOME SECURITIES, INC. NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2006 (UNAUDITED) which are listed on U.S. and foreign stock exchanges normally are valued at the last sale price on the day the securities are valued or, lacking any sales on such day, at the last available bid price. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by UBS Global Asset Management (Americas) Inc. ("UBS Global AM" or the "Advisor"), the investment advisor 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 and Basel, Switzerland and operations in many areas of the financial services industry. 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. Certain securities in which the Fund invests are traded in markets that close before 4:00 p.m. Eastern time. Normally, developments that occur between the close of the foreign markets and 4:00 p.m. Eastern time will not be reflected in the Fund's NAV. However, such developments may be determined to be so significant that they will materially affect the value of the Fund's securities. The Fund may use a systematic fair valuation model provided by an independent third party to value securities principally traded in foreign markets in order to adjust for possible stale pricing that may occur between the close of the foreign exchanges and time for valuation. If a security is valued at a "fair value", that value is likely to be different from the last quoted market price for the security. Previous closing prices may be adjusted to reflect what the Board believes to be fair value of these securities as of 4:00 p.m. Eastern time. MORTGAGE-BACKED SECURITIES AND OTHER INVESTMENTS--The Fund invests in Mortgage-Backed Securities (MBS), representing interests in pools of mortgage loans. These securities provide shareholders with payments consisting of both principal and interest as the mortgages in the underlying mortgage pools are paid. MBS issued by private entities are not government securities and are not directly guaranteed by any government agency. They are secured by the underlying collateral of the private issuer. Yields on privately issued MBS tend to be higher than those of government backed issues. However, risk of loss due to default and sensitivity to interest rate fluctuations is also higher. -------------------------------------------------------------------------------- 19 FORT DEARBORN INCOME SECURITIES, INC. NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2006 (UNAUDITED) The Fund invests in Collateralized Mortgage Obligations (CMOs). A CMO is a bond, which is collateralized by a pool of MBS. The Fund may also invest in REMICs (Real Estate Mortgage Investment Conduit) which are simply another form of CMO. These MBS pools are divided into classes or tranches with each class having its own characteristics. The different classes are retired in sequence as the underlying mortgages are repaid. For instance, a Planned Amortization Class(PAC) is a specific class of mortgages, which over its life will generally have the most stable cash flows and the lowest prepayment risk. A Graduated Payment Mortgage (GPM) is a negative amortization mortgage where the payment amount gradually increases over the life of the mortgage. The early payment amounts are not sufficient to cover the interest due, and therefore, the unpaid interest is added to the principal, thus increasing the borrower's mortgage balance. Prepayment may shorten the stated maturity of the CMO and can result in a loss of premium, if any has been paid. The Fund invests in Asset-Backed Securities, representing interests in pools of certain types of underlying installment loans or leases or by revolving lines of credit. They often include credit enhancement that help limit investors exposure to the underlying credit. These securities are valued on the basis of timing and certainty of cash flows compared to investments with similar durations. INFLATION PROTECTED SECURITIES--Inflation protected securities are debt securities whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. Inflation-protected securities include Treasury Inflation Protected Securities ("TIPS"), which are securities issued by the U.S. Treasury. The interest rate paid by TIPS is fixed, while the principal value rises or falls based on changes in a published Consumer Price Index ("CPI"). Thus, if inflation occurs, the principal and interest payments on the TIPS are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the TIPS' principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, TIPS generally pay lower interest rates than typical U.S. Treasury securities. Only if inflation occurs will TIPS offer a higher real yield than a conventional Treasury bond of the same maturity. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--Investment transactions are recorded on the trade date. Realized gains and losses from investment and foreign exchange transactions are calculated using the identified cost method. Interest income is recorded on an accrual basis. -------------------------------------------------------------------------------- 20 FORT DEARBORN INCOME SECURITIES, INC. NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2006 (UNAUDITED) Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments. DIVIDENDS AND DISTRIBUTIONS--Dividends and distributions to shareholders are recorded on the ex-dividend date. The amount of dividends from net investment income and distributions from net realized capital gains and/or return of capital is determined in accordance with U.S. 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. CONCENTRATION OF RISK--The ability of the issuers of the debt securities held by the Fund to meet their obligations may be affected by economic developments, including those particular to a specific industry or region. CAPITAL STOCK At March 31, 2006, there were 12,000,000 shares of $0.01 par value capital stock authorized, and 8,775,665 shares issued and outstanding. During the six months ended March 31, 2006, no new shares were issued as part of the dividend reinvestment plan. INVESTMENT ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES Under an agreement between the Fund and UBS Global AM, UBS Global AM manages the Fund's investment portfolio, maintains its accounts and records, and furnishes the services of individuals to perform executive functions for the Fund. In return for these services, the Fund pays UBS Global AM 0.50% per annum of the Fund's average weekly net assets up to $100,000,000 and 0.40% per annum of average weekly net assets in excess of $100,000,000. At March 31, 2006, the Fund owed UBS Global AM $160,717 in investment advisory fees. The Fund invests in shares of the UBS Supplementary Trust -- U.S. Cash Management Prime Fund ("Supplementary Trust"). Supplementary Trust is a business trust managed by the Advisor. Supplementary Trust is offered as a cash management option only to mutual funds and other accounts managed by the Advisor. The Fund pays no management fees to Supplementary Trust. Distributions from the Supplementary Trust are reflected as affiliated interest income on the statement of operations. Amounts relating to those investments -------------------------------------------------------------------------------- 21 FORT DEARBORN INCOME SECURITIES, INC. NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2006 (UNAUDITED) at March 31, 2006 and for the six month period ended are summarized as follows: % OF SALES INTEREST NET FUND PURCHASES PROCEEDS INCOME VALUE ASSETS --------------------------------------------------------------------------------------------------- UBS Supplementary Trust -- U.S. Cash Management Prime Fund $17,632,154 $17,627,433 $46,582 $1,943,044 1.43% =================================================================================================== PURCHASES AND SALES OF SECURITIES Purchases and sales (including maturities) of portfolio securities during the six months ended March 31, 2006, were as follows: debt securities, excluding short-term securities and U.S. government debt obligations, $17,585,076 and $26,158,099, respectively; and U.S. government debt obligations, $31,364,429 and $25,004,438, respectively. FEDERAL TAX STATUS The Fund intends to distribute substantially all of its 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, 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 year ended September 30, 2005 were as follows: DISTRIBUTIONS PAID FROM: ------------------------------------------------------------------------------- Ordinary income $7,210,549 ------------------------------------------------------------------------------- Long-Term capital gains 933,268 ------------------------------------------------------------------------------- $8,143,817 =============================================================================== At September 30, 2005, the components of accumulated earnings on a tax basis were as follows: Undistributed ordinary income $1,326,246 ------------------------------------------------------------------------------- Undistributed long-term capital gains 193,547 ------------------------------------------------------------------------------- Net unrealized appreciation of investments 5,830,714 ------------------------------------------------------------------------------- Total accumulated earnings $7,350,507 =============================================================================== -------------------------------------------------------------------------------- 22 FORT DEARBORN INCOME SECURITIES, INC. NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2006 (UNAUDITED) The tax character of distributions paid and components of accumulated earnings (deficit) on a tax basis for the current fiscal year will be calculated after the Fund's fiscal year ended September 30, 2006. The difference between book-basis and tax-basis net unrealized appreciation of investments is attributable to the tax deferral of losses on wash sales. During the fiscal year ended September 30,2005, the Fund had no capital loss carry-forwards to offset current year gains. For federal income tax purpose, which was substantially the same for book purposes, tax cost of investments and components of net unrealized appreciation of investments at March 31, 2006 were as follows: Tax cost of investments $133,814,484 -------------------------------------------------------------------------------------------- Gross appreciation (investments having an excess of value over cost) 3,440,079 -------------------------------------------------------------------------------------------- Gross depreciation (investments having an excess of cost over value) (2,756,492) -------------------------------------------------------------------------------------------- Net unrealized appreciation of investments $683,587 ============================================================================================ To reflect reclassifications arising from permanent "book/tax" differences for the year ended September 30, 2005, accumulated undistributed net investment income was increased by $200,558 and accumulated net realized gain from investment activities was decreased by $200,558. These differences are primarily due to paydown losses. -------------------------------------------------------------------------------- 23 FORT DEARBORN INCOME SECURITIES, INC.

DIVIDEND REINVESTMENT PLAN The Fund has established a dividend reinvestment plan (the "Plan") under which all shareholders whose shares are registered in their own names, or in the name of a participating broker or its nominee, may elect to have all dividends and other distributions automatically reinvested in additional Fund shares. Shareholders who elect to hold their shares in the name of a 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. More information regarding the Plan is provided below. -------------------------------------------------------------------------------- 26 FORT DEARBORN INCOME SECURITIES, INC. GENERAL INFORMATION (UNAUDITED) The Plan is applicable in each case where the Fund declares a dividend or other distribution payable in cash and simultaneously gives to its shareholders who are participants under the Plan ("Participants") the option to receive such dividend or other distribution in Fund shares. Commencing seven trading days prior to the date of payment of such dividend or other distribution, but only if the market price plus brokerage commission at the time of purchase is lower than the net asset value as of the close of business on the eighth trading day prior to such date of payment ("Base Net Asset Value"), the agent (the "Agent"), on behalf of the Participants, will purchase shares in the open market(s) available to it. There can be no assurance that shares will be available in such open market(s) at a cost lower than Base Net Asset Value or in sufficient quantities to permit such purchases by the Agent. These purchases may be made on any securities exchange where such shares are traded, in the over-the-counter market or by negotiated transactions and may be subject to such terms of price, delivery, etc., to which the Agent may agree. If the market price for the shares is greater than the net asset value as of the close of business on the eight trading day prior to the date of payment, then the Fund will issue shares in payment of the dividend. On the date of payment of such dividend or other distribution, the Agent will elect to have the Fund pay the dividend or other distribution in cash to the extent of the cost, including brokerage commission, of the shares to be purchased by the Agent, and will elect to have the Fund pay the balance, if any, of the dividend or other distribution in shares. Such payments will be made by the Fund to Computershare Trust Company, N.A. ("Computershare") as administrator of the Plan for the Participants. Computershare, in turn, will immediately settle the open market purchases with the Agent. If shares are distributed in payment of a dividend or distribution because market price exceeded net asset value, a Participant will be required to include in gross income an amount equal to the greater of net asset value or 95% of fair market value (average of the high and low sales price on the date of the distribution) of the shares received by the Participant rather than the amount of such dividend. Distributions of shares will be subject to the right of the Fund to take such actions as may be deemed necessary in order to comply with or conform to the requirements of any applicable law or regulation. The shares credited to the accounts of Participants at Computershare will be determined on the basis of the amount of dividend or distribution to which each Participant is entitled, whether shares are purchased on the open market or issued by the Fund. Each Participant will be furnished with periodic statements. -------------------------------------------------------------------------------- 27 FORT DEARBORN INCOME SECURITIES, INC. GENERAL INFORMATION (UNAUDITED) A Participant will have the right to vote the full shares credited to the Participant's account under the Plan on the record date for a vote. Proxies sent to a Participant by Computershare will include the number of full shares held for the Participant under the Plan. The investment of dividends and distributions under the Plan does not relieve the Participant of any income tax which may be payable on such dividends or distributions. Annually, each participant will be provided with information for tax purposes with respect to the dividends and distributions on the shares held for the account of the Participant. The Fund strongly recommends that all Participants retain each year's final statement on their Plan participation as a part of their permanent tax record. Shareholders who wish to elect to participate in the Plan should contact Computershare for further information. A Participant may terminate participation in the Plan at any time by notice in writing to Computershare. All correspondence concerning the Plan should be directed to Computershare at Computershare Dividend Reinvestment Services, P.O. Box 43081, Providence, RI 02940-3081. You may also contact Computershare directly at 1-800-446 2617. In order to be effective on the payment date of any dividend or distribution, notice of such termination must be received by Computershare before the record date for the payment of such dividend or distribution. If a notice to discontinue is received by Computershare on or after the record date for a dividend payment, such notice to discontinue may not become effective until such dividend has been reinvested and the shares purchased are credited to the Participant's account under the Plan. Computershare, in its sole discretion, may either pay such dividend in cash or reinvest it in shares on behalf of the terminating Participant. Computershare may terminate, for whatever reason at any time as it may determine in its sole discretion, an individual's participation in the Plan upon mailing a notice of termination to the Participant at the Participant's address as it appears on Computershare's records. When an account is terminated, the Participant will receive a certificate for the number of full shares credited to the Participant's account under the Plan, unless the sale of all or part of such shares is requested. Such sale may, but need not, be made by purchase of the shares for the account of other Participants and any such transaction shall be deemed to have been made at the then current market price less any applicable brokerage commissions and any other costs of sale. The terminating Participant's fractional share interest in the Plan will be aggregated with -------------------------------------------------------------------------------- 28 FORT DEARBORN INCOME SECURITIES, INC. GENERAL INFORMATION (UNAUDITED) the fractional share interests of another terminating Participants and sold. The net proceeds of such sales will be distributed to the Participants in payment for their fractional share interests. The Fund may terminate or amend the Plan upon thirty (30) days' notice in writing to each Participant, such termination or amendment to be effective as to all dividends and distributions payable to shareholders of record on any date more than thirty (30) days after mailing of such notice. There is no direct service charge (other than brokerage commissions) by the Agent to Participants in the Plan. All costs of the Plan, except brokerage commissions, will be paid by the Fund. However, the Fund reserves the right to amend the Plan in the future to include a service charge. -------------------------------------------------------------------------------- 29 (This page has been left blank intentionally) -------------------------------------------------------------------------------- 30 (This page has been left blank intentionally) -------------------------------------------------------------------------------- 31 (This page has been left blank intentionally) -------------------------------------------------------------------------------- 32 DIRECTORS Adela Cepeda Frank K.
