Reports to Stockholders [PHOTO] COLONIAL HIGH INCOME MUNICIPAL TRUST Semiannual Report May 31, 2006 [LOGO] Not FDIC Insured May Lose Value No Bank Guarantee [GRAPHIC] Dear Shareholder: The US stock and bond markets delivered positive, but modest, returns during the six month period ended May 31, 2006. After a weak fourth quarter, economic growth turned sharply higher in 2006 and job growth was steady, although somewhat slower at the end of the period. Confident consumers continued to pump dollars into US retail markets, despite higher energy prices, which boosted inflation. The housing market continued to cool as mortgage rates moved higher, but housing-market indicators--such as housing starts, sales of existing homes, and house prices--remained strong by historical measures. In this environment, the US fixed income markets faced the challenge of rising interest rates, especially within the short-and intermediate-maturity ranges and was generally flat for the period. The Federal Reserve Board, in an effort to balance economic growth and the forces of inflation, raised short-term interest rates by one full percentage point during the reporting period. The yield on the 10-year US Treasury note, a bellwether for the bond market, moved up from 4.5% to 5.1%. Lower quality bonds did better than higher quality bonds. In fact, high-yield bonds did better than either stocks or investment-grade bonds. A strong economy favored corporate high-yield bonds, as default rates remained low and corporate profits surprised investors with better-than-expected results. However, that trend showed signs of shifting near the end of the six-month period. The municipal sector generated respectable gains as economic growth helped buoy revenues and stabilize budgets in many states and municipalities. Within the municipal market, high-yield also outperformed high-grade bonds for the period. In the pages that follow, your fund's manager discusses key factors that influenced performance during this six-month reporting period. We urge you to read this report carefully and to discuss any questions you might have with your financial advisor. As always, we thank you for choosing Colonial Funds. We look forward to continuing to help you build toward your financial goals. Sincerely, /s/ Christopher L. Wilson Christopher L. Wilson President, Columbia Funds Past performance is no guarantee of future results. Investments in high-yield or "junk" bonds offer the potential for higher income than investments in investment-grade bonds, but also have a higher degree of risk. Changes in economic conditions or other circumstances may adversely effect a high-yield bond issuer's ability to make timely principal and interest payments. The views expressed in the President's Message and Portfolio Manager's Report reflect the current views of the respective parties. These views are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict so actual outcomes and results may differ significantly from the views expressed. These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Colonial Fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Colonial Fund. References for specific company securities should not be construed as a recommendation or investment advice. [GRAPHIC] [GRAPHIC] PORTFOLIO MANAGER'S REPORT SUMMARY .. For the six-month period ended May 31, 2006, Colonial High Income Municipal Trust generated a total return of 8.70%, based on its market price. During this period, the trust returned 4.19%, based on investment at net asset value. This was less than the 4.41% average return of the Lipper High Yield Municipal Debt Funds Category./1/ The trust's performance was much closer to the 4.30% average return generated by a customized peer group consisting of nine leveraged closed-end high-yield municipal funds that have all issued preferred shares. The trust's dividend yield declined as rising short-term interest rates cut into some of the income that the trust derived from leverage. However, we believe that the trust's leverage continued to give the common shareholders a higher dividend payment than would have been available without it. .. Strong gains from the multi-family housing sector and assisted living projects bolstered returns. In addition, the trust's slightly longer duration (a measure of bond price volatility) helped as long-term municipal yields dropped slightly. The trust's slight overweight in higher quality issues hampered performance as did its underweight in the volatile airline sector. While airline holdings added to total return, the trust had less exposure than some of its competitors to this top-performing sector. In addition, some nursing home bonds fell due to credit deterioration. .. At the end of the period, the trust had a slightly higher emphasis than its peers on higher quality bonds, which we expect to do well if the difference in yields between higher and lower quality bonds widens. We also kept the trust's duration slightly longer than its peers because we do not expect long-term interest rates to move much higher. We expect the Federal Reserve Board to remain vigilant on inflation, which could benefit long-term bonds, whose yields tend to reflect inflation expectations. PORTFOLIO MANAGEMENT Maureen G. Newman has been the portfolio manager of Colonial High Income Municipal Trust since August 1998. SHARES OF CLOSED-END FUNDS FREQUENTLY TRADE AT A DISCOUNT TO NET ASSET VALUE. THE PRICE OF THE TRUST'S SHARES IS DETERMINED BY A NUMBER OF FACTORS, SEVERAL OF WHICH ARE BEYOND THE CONTROL OF THE TRUST. THEREFORE, THE TRUST CANNOT PREDICT WHETHER ITS SHARES WILL TRADE AT, BELOW OR ABOVE NET ASSET VALUE.

Distributions declared per common share 12/01/05-05/31/06 ($) 0.22 -------- A portion of the trust's income may be subject to the alternative minimum tax. The trust may at times purchase tax-exempt securities at a discount from their original issue price. Some or all of this discount may be included in the trust's ordinary income, and any market discount is taxable when distributed.

Ratings shown in the quality breakdown represent the rating assigned to a particular bond by one of the following nationally-recognized rating agencies: Standard & Poor's, a division of the McGraw-Hill Companies, Inc., Moody's Investors Service, Inc. or Fitch Ratings Ltd. The majority of the bonds that are non-rated are considered by the advisor to be of non-investment grade quality. Ratings are relative and subjective and are not absolute standards of quality. The fund's credit quality does not remove market risk. 1 [GRAPHIC] PORTFOLIO MANAGER'S REPORT (continued) Investing in fixed-income securities may involve certain risks, including the credit quality of individual issuers, possible prepayments, market or economic developments and yield and share price fluctuations due to changes in interest rates. When interest rates go up, bond prices typically drop, and vice versa. Investing in high-yield or "junk" bonds offers the potential for higher income than investments in investment-grade bonds but they also have a higher degree of risk. Changes in economic conditions or other circumstances may adversely affect a high-yield bond issuer's ability to make timely principal and interest payments. Tax-exempt investing offers current tax-exempt income, but it also involves special risks. The value of the trust will be affected by interest rate changes and the creditworthiness of issues held in the fund. Interest income from certain tax-exempt bonds may be subject to certain state and local taxes and, if applicable, the alternative minimum tax. Capital gains are not exempt from income taxes.

See Accompanying Notes to Financial Statements. 21 [GRAPHIC] NOTES TO FINANCIAL STATEMENTS May 31, 2006 (Unaudited) NOTE 1. ORGANIZATION Colonial High Income Municipal Trust (the "Trust") is a Massachusetts business trust registered under the Investment Company Act of 1940 (the "Act"), as amended, as a diversified, closed-end management investment company. INVESTMENT GOAL The Trust seeks to provide high current income, generally exempt from federal income taxes. The Trust's secondary goal is to seek total return. TRUST SHARES The Trust may issue an unlimited number of common shares. On August 26, 1999, the Trust issued 4,800 Auction Preferred Shares ("APS"). NOTE 2. SIGNIFICANT ACCOUNTING POLICIES USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements. SECURITY VALUATION Debt securities generally are valued by pricing services approved by the Trust's Board of Trustees, based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes. Debt securities for which quotations are readily available are valued at an over-the-counter or exchange bid quotation. Certain debt securities, which tend to be more thinly traded and of lesser quality, are priced based on fundamental analysis of the financial condition of the issuer and the estimated value of any collateral. Valuations developed through pricing techniques may vary from the actual amounts realized upon sale of the securities, and the potential variation may be greater for those securities valued using fundamental analysis. Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value. Investments in open-end investment companies are valued at net asset value. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded. Investments for which market quotations are not readily available, or that have quotations which management believes are not appropriate, are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. If a security is valued at "fair value", such value is likely to be different from the last quoted market price for the security. SECURITY TRANSACTIONS Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes. FUTURES CONTRACTS The Trust may invest in municipal and U.S. Treasury futures contracts. The Trust will invest in these instruments to hedge against the effects of changes in the value of portfolio securities due to anticipated changes in interest rates and/or market conditions, for duration management, or when the transactions are economically appropriate to the reduction of risk inherent in the management of the Trust and not for trading purposes. The use of futures contracts involves certain risks, which include: (1) imperfect correlation between the price movement of the instruments and the underlying securities, (2) inability to close out positions due to differing trading hours, or the temporary absence of a liquid market, for either the instrument or the underlying securities, or (3) an inaccurate prediction by Columbia Management Advisors, LLC of the future direction of interest rates. Any of these risks may involve amounts exceeding the variation margin recorded in the Trust's Statement of Assets and Liabilities at any given time. Upon entering into a futures contract, the Trust deposits cash or securities with the broker in an amount sufficient to meet the initial margin requirement. Subsequent payments are made or received by the Trust equal to the daily change in the contract value and are recorded as variation margin receivable or payable and offset in unrealized gains or losses. The Trust also identifies portfolio securities as segregated with the custodian in a separate account in an amount equal to the futures contract. The Trust recognizes a realized gain or loss when the contract is closed or expires. 22 [GRAPHIC] NOTES TO FINANCIAL STATEMENTS (continued) May 31, 2006 (Unaudited) SWAPS The Trust may engage in swap transactions such as interest rate, forward, total return, index or currency swaps, consistent with its investment objective and policies to obtain a desired return at a lower cost than if the Trust had invested directly in the asset that yielded the desired return. Swaps involve the exchange by the Trust with another party of their respective commitments to pay or receive interest or total return throughout the lives of the agreements. The interest to be paid or received on swaps is included in net realized gain/(loss) on investments. Unrealized gains are reported as an asset and unrealized losses are reported as a liability on the Statement of Assets and Liabilities. A realized gain or loss is recorded upon termination of swap agreements and is equal to the difference between the Trust's basis in the swap and the proceeds from (or cost of) the closing transaction. Swap agreements are stated at fair value. Notional principal amounts are used to express the extent of involvement in these transactions, but the amounts potentially subject to credit risk are much smaller. If there is a default by the counterparty to a swap contract, the Trust will be limited to contractual remedies pursuant to the agreements related to the transaction. There is no assurance that the swap contract counterparties will be able to meet their obligations pursuant to the swap contracts or that, in the event of default, the Trust will succeed in pursuing contractual remedies. The Trust thus assumes the risk that it may be delayed in or prevented from obtaining payments owed to it pursuant to the swap contracts. The use of derivative instruments involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statements of assets and liabilities. RESTRICTED SECURITIES Restricted securities are securities that may only be resold upon registration under federal securities laws or in transactions exempt from registration. In some cases, the issuer of restricted securities has agreed to register such securities for resale at the issuer's expense either upon demand by the Trust or in connection with another registered offering of the securities. Many restricted securities may be resold in the secondary market in transactions exempt from registration. Such restricted securities may be determined to be liquid under criteria established by the Board of Trustees. The Trust will not incur any registration costs upon such resale. DELAYED DELIVERY SECURITIES The Trust may trade securities on other than normal settlement terms, including securities purchased or sold on a "when-issued" basis. This may increase the risk if the other party to the transaction fails to deliver and causes the Trust to subsequently invest at less advantageous prices. The Trust identifies cash or liquid portfolio securities as segregated with the custodian in an amount equal to the delayed delivery commitment. INCOME RECOGNITION Interest income is recorded on the accrual basis. Premium and discount are amortized and accreted, respectively, on all debt securities. Corporate actions and dividend income are recorded on the ex-date. FEDERAL INCOME TAX STATUS The Trust intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its taxable income, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Trust intends to distribute in each calendar year substantially all of its net investment income, capital gains and certain other amounts, if any, such that the Trust should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded. DISTRIBUTIONS TO SHAREHOLDERS Distributions to common shareholders are recorded on the ex-date. Distributions to Auction Preferred shareholders are recorded daily and payable at the end of each dividend period. Each dividend payment period for the APS is generally seven days. The applicable dividend rate for the APS on May 31, 2006, was 3.35% for Series T and 3.41% for Series W. For the six months ended May 31, 2006, the Trust declared dividends to Auction Preferred shareholders amounting to $1,915,402 representing an average dividend rate of 3.23% per APS. NOTE 3. FEDERAL TAX INFORMATION The tax character of distributions paid during the year ended November 30, 2005 was as follows: Distributions paid from: Tax-Exempt Income $16,903,320 Ordinary Income -- Long-Term Capital Gains -- Unrealized appreciation and depreciation at May 31, 2006, based on cost of investments for federal income tax purposes, was: Unrealized appreciation $ 16,172,702 Unrealized depreciation (11,763,711) ------------ Net unrealized appreciation $ 4,408,991 ------------ 23 [GRAPHIC] NOTES TO FINANCIAL STATEMENTS (continued) May 31, 2006 (Unaudited) The following capital loss carryforwards may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code: YEAR OF CAPITAL LOSS EXPIRATION CARRYFORWARD ------------ -------------- 2007 3,941,668 2008 14,340,573 2009 4,198,716 2010 12,980,738 2011 4,761,736 2012 4,055,363 ----------- $44,278,794 ----------- Capital loss carryforwards of $1,444,131 were utilized and $4,482,522 expired during the year ended November 30, 2005 for the Trust. Expired capital loss carryforwards are recorded as a reduction of paid-in capital. NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES INVESTMENT ADVISORY FEE Columbia Management Advisors, LLC ("Columbia"), an indirect, wholly-owned subsidiary of Bank of America Corporation ("BOA"), is the investment advisor to the Trust and provides administrative and other services. Columbia receives a monthly investment advisory fee at the annual rate of 0.75% of the Trust's average weekly net assets, including assets applicable to the APS. PRICING AND BOOKKEEPING FEES Columbia is responsible for providing pricing and bookkeeping services to the Trust under a pricing and bookkeeping agreement. Under a separate agreement (the "Outsourcing Agreement"), Columbia has delegated those functions to State Street Corporation ("State Street"). As a result, Columbia pays State Street the total fees collected under the pricing and bookkeeping agreement. Under its pricing and bookkeeping agreement with the Trust, Columbia receives an annual fee of $38,000 paid monthly plus an additional monthly fee based on the level of average daily net assets for the month; provided that during any 12-month period, the aggregate fee, exclusive of out-of-pocket expenses and charges, shall not exceed $140,000. The Trust also reimburses Columbia and State Street for out-of-pocket expenses and charges, including fees payable to third parties for pricing the Trust's portfolio securities and direct internal costs incurred by Columbia in connection with providing fund accounting oversight and monitoring and certain other services. For the six months ended May 31, 2006, the annualized effective pricing and bookkeeping fee rate for the Trust, inclusive of out-of-pocket expenses, was 0.047% of the Trust's average daily net assets. CUSTODY CREDITS The Trust has an agreement with its custodian bank under which custody fees may be reduced by balance credits. These credits are recorded as a reduction of total expenses on the Statement of Operations. The Trust could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. FEES PAID TO OFFICERS AND TRUSTEES All officers of the Trust, with the exception of the Trust's Chief Compliance Officer, are employees of Columbia or its affiliates and receive no compensation from the Trust. The Board of Trustees has appointed a Chief Compliance Officer to the Trust in accordance with federal securities regulations. The Trust, along with other affiliated funds, pays its pro-rata share of the expenses associated with the Chief Compliance Officer. The Trust's expenses for the Chief Compliance Officer will not exceed $15,000 per year. The Trust's Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Trust's assets. OTHER Columbia provides certain services to the Trust related to Sarbanes-Oxley compliance. For the six months ended May 31, 2006, the Trust paid $1,246 to Columbia for such services. This amount is included in "Other expenses" on the Statement of Operations. NOTE 5. PORTFOLIO INFORMATION For the six months ended May 31, 2006, the cost of purchases and proceeds from sales of securities, excluding short-term obligations, were $64,928,825 and $35,590,131, respectively. NOTE 6. PREFERRED SHARES The Trust currently has outstanding 4,800 APS (2,400 shares each of Series T and W). The APS are redeemable at the option of the Trust on any dividend payment date at the redemption price of $25,000 per share, plus an amount equal to any dividends accumulated on a daily basis unpaid through the redemption date (whether or not such dividends have been declared). 24 [GRAPHIC] NOTES TO FINANCIAL STATEMENTS (continued) May 31, 2006 (Unaudited) Under the Act, the Trust is required to maintain asset coverage of at least 200% with respect to the APS as of the last business day of each month in which any APS are outstanding. Additionally, the Trust is required to meet more stringent asset coverage requirements under the terms of the APS Agreement and in accordance with the guidelines prescribed by the APS' rating agencies. Should these requirements not be met, or should dividends accrued on the APS not be paid, the Trust may be restricted in its ability to declare dividends to common shareholders or may be required to redeem certain APS. At May 31, 2006, there were no such restrictions on the Trust. NOTE 7. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES CONCENTRATION OF CREDIT RISK The Trust holds investments that are insured by private insurers who guarantee the payment of principal and interest in the event of default or that are supported by a letter of credit. Each of the Trust's insurers is rated Aaa by Moody's Investor Services Inc., except for Radian Asset Assurance, Inc., which is rated Aa3. At May 31, 2006, private insurers who insured greater than 5% of the total investments of the Trust were as follows: % OF TOTAL INSURER INVESTMENTS --------------------------------- Ambac Assurance Corp. 7.1% GEOGRAPHIC CONCENTRATION The Trust has greater than 5% of its total investments at May 31, 2006 invested in debt obligations issued by the states of California, Colorado, Florida, Illinois and Pennsylvania and their respective political subdivisions, agencies and public authorities. The Trust is more susceptible to economic and political factors adversely affecting issuers of the specific state's municipal securities than are municipal bond funds that are not concentrated to the same extent in these issuers. HIGH-YIELD SECURITIES Investing in high-yield securities may involve greater credit risk and considerations not typically associated with investing in U.S. government bonds and other higher quality fixed income securities. These securities are non-investment grade securities, often referred to as "junk" bonds. Economic downturns may disrupt the high yield market and impair the ability of issuers to repay principal and interest. Also, an increase in interest rates would likely have an adverse impact on the value of such obligations. Moreover, high-yield securities may be less liquid to the extent that there is no established secondary market. INDUSTRY FOCUS The Trust may focus its investments in certain industries, subjecting it to greater risk than a trust that is more diversified. LEGAL PROCEEDINGS On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004. Under the terms of the SEC Order, the Columbia Group agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce management fees for certain Columbia Funds (including the former Nations Funds) and other mutual funds collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions. Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and approved by the SEC. The independent distribution consultant has been in consultation with the staff of the SEC and has submitted a proposed plan of distribution. The SEC has not yet approved a final plan of distribution. 25 [GRAPHIC] NOTES TO FINANCIAL STATEMENTS (continued) May 31, 2006 (Unaudited) As a result of these matters or any adverse publicity or other developments resulting from them, the market price of the shares could decline. A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005. In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the ''MDL''). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law. On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds Trusts and the Columbia Acorn Trust. As to Columbia, and the Distributor, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 ("ICA") and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed. On March 21, 2005, a purported class action was filed in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL. The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made. In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending. 26 [GRAPHIC] ASSET COVERAGE REQUIREMENTS INVOLUNTARY ASSET LIQUIDATING AVERAGE TOTAL AMOUNT COVERAGE PREFERENCE MARKET VALUE OUTSTANDING PER SHARE* PER SHARE PER SHARE ------------------------------------------------------------ 05/31/06** $120,000,000 $67,382 $25,009 $25,000 11/30/05 120,000,000 67,014 25,009 25,000 11/30/04 120,000,000 66,479 25,008 25,000 11/30/03 120,000,000 67,605 25,003 25,000 11/30/02 120,000,000 67,243 25,002 25,000 11/30/01 120,000,000 69,864 25,004 25,000 11/30/00 120,000,000 69,786 25,009 25,000 11/30/99*** 120,000,000 73,466 25,021 25,000 *Calculated by subtracting the Trust's total liabilities from the Trust's total assets and dividing the amount by the number of APS outstanding. **Unaudited. ***On August 26, 1999, the Trust began offering Auction Preferred Shares.

On March 10, 2006, the record date for the Meeting, the Trust had 31,191,047 common shares outstanding and 4,800 preferred shares. The votes cast were as follows: ELECTION OF TRUSTEES: The shareholders re-elected the following Trustees as follows: FOR WITHHELD ---------------------------------------- Janet Langford Kelly 27,687,178 404,124 Anne-Lee Verville 27,697,445 393,857 The holders of preferred shareholders re-elected the following Trustees as follows: FOR WITHHELD -------------------------------- Douglas A.

Simpson continued after the Meeting. 28 [GRAPHIC] DIVIDEND REINVESTMENT PLAN COLONIAL HIGH INCOME MUNICIPAL TRUST Shareholders may elect to have all distributions of dividends and capital gains automatically reinvested by Computershare (the "Plan Agent"), as agent under the Trust's Dividend Reinvestment Plan (the "Plan"). Pursuant to the Plan, the provisions of which are described below, shareholders not making such an election will receive all such amounts in cash paid by check mailed directly to the shareholder by the Plan Agent, as the dividend paying agent. If the Trustees of the Trust declare a dividend or determine to make a capital gain distribution payable either in shares of the Trust or in cash, as shareholders may have elected, nonparticipants in the Plan will receive cash and participants in the Plan will receive the equivalent in shares of the Trust. If the market price of the shares on the payment date for the dividend or distribution is equal to or exceeds their net asset value, participants will be issued shares of the Trust at the higher of net asset value or 95% of the market price. If the net asset value exceeds the market price of Trust shares at such time, or if the Trust declares a dividend or other distribution payable only in cash, the Plan Agent will, as agent for Plan participants, buy Trust shares in the open market, on the New York Stock Exchange or elsewhere, for the participants' accounts. If, before the Plan Agent has completed its purchases, the market price exceeds the net asset value of the Trust's shares, the average per share purchase price paid by the Plan Agent may exceed the net asset value of the Trust's shares, resulting in the acquisition of fewer shares than if the dividend or distribution had been paid in shares issued by the Trust. In circumstances in which the net asset value of Trust shares is more than 5% below their market price, participants in the Plan will be issued shares through the Plan at a price exceeding net asset value. Participants in the Plan may withdraw from the Plan upon written notice to the Plan Agent. When a participant withdraws from the Plan or upon termination of the Plan as provided below, certificates for whole shares credited to the participant's account under the Plan will be issued and a cash payment will be made for any fraction of a share credited to such account. A shareholder's notice of election to participate in or withdraw from the Plan must be received by the Plan Agent before the record date for a dividend in order to be given effect with respect to that dividend. In the case of shareholders such as banks, brokers or nominees holding shares for others who are the beneficial owners of those shares, the Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by the shareholder of record as representing the total amount registered in such shareholder's name and held for the account of beneficial owners who are to participate in the Plan. There is no charge to Plan participants for reinvesting dividends or distributions. The Plan Agent's fees for the handling of the reinvestment of dividends and distributions will be paid by the Trust. There will be no brokerage charges with respect to shares issued directly by the Trust as a result of dividends or distributions payable either in stock or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open market purchases in connection with the reinvestment of dividends or distributions. The automatic reinvestment of dividends and distributions will not relieve participants of any income tax that may be payable on such dividends or distributions. The Plan may be amended or terminated on 30 days written notice to Plan participants. Contact the Plan Agent for more information regarding the Plan. All correspondence concerning the Plan should be directed to Computershare by mail at P.O. Box 43010, Providence, RI 02940-3010, or by phone at 1-800-730-6001. 29 [LOGO] Transfer Agent Important Information About This Report The Transfer Agent for Colonial High Income Municipal Trust is: Computershare P.O.
