COLONIAL INVESTMENT GRADE MUNICIPAL TRUST ANNUAL REPORT NOVEMBER 30, 2002 [PHOTO] PRESIDENT'S MESSAGE DEAR SHAREHOLDER: For a third consecutive year, the municipal bond market offered positive returns. In general, the bond market was aided by strong demand, as investors shied away from the stock market in light of economic uncertainty, corporate scandals and the threat of war. Relatively stable interest rates were also an aid to market performance. The Federal Reserve lowered short-term interest rates early in the period and again late in the period as the economy struggled and consumer confidence sagged. The volume of new municipal bonds increased as cities and states faced budget deficits and revenue shortfalls. However, investor demand for bonds also rose, and that helped support returns throughout the year. The following report will provide you with more detailed information about the fund's performance and the investment strategies used by portfolio manager Maureen Newman. As always, we thank you for choosing Colonial Investment Grade Municipal Fund and for giving us the opportunity to help you build a strong financial future. /s/ Keith T. Banks Keith T.

There is no assurance that the trends described in this report will continue or commence. PORTFOLIO MANAGER'S REPORT For the 12-month period ended November 30, 2002, Colonial Investment Grade Municipal Trust generated a total return of 6.36%, based on net asset value. The trust outperformed the average 6.26% return of its peer group, the Lipper General Municipal Debt Funds (Leveraged). During the fiscal year, uncertainty pervaded the financial markets as weak economic growth, concerns about corporate governance and geopolitical issues dominated market sentiment. In this environment, investors sought safe havens for their assets, and many turned to high-quality municipal bonds. Because the trust had invested significant assets in high-quality, long duration bonds, it was well positioned to take advantage of this emphasis on quality. (Duration measures a bond's sensitivity to interest rate changes. See sidebar). The long duration bonds in the portfolio were strong performers during market rallies and the biggest contributors to the trust's return. The trust's leverage also boosted its income stream, which, in turn, enhanced the income available for distribution to the trust's shareholders. Toward the end of the fiscal year, we sold some of the bonds that had performed well and invested the proceeds in lower-rated investment grade bonds, which were laggards for the entire fiscal period. We believe these securities have the potential to perform well as economic growth improves. When adding bonds to the portfolio, we found some of the best values in school districts, which are supported by property taxes, and in the electric utility and housing sectors. We have structured the portfolio to take advantage of a slowly improving economy and a stable or slightly rising interest-rate environment. Because most states project large budgetary imbalances, we have been cautious about investing in areas that depend on state government spending and that may be affected by spending cuts. We believe some of the best opportunities will continue to come from the essential services sectors, such as utilities and water and sewer. /s/ Maureen G. Newman Maureen G. Newman Maureen G.

Past performance is no guarantee of future investment results. The principal value and investment returns will fluctuate, resulting in a gain or loss on sale. Tax-exempt investing offers current tax-free income, but it also involves certain risks. The value of the trust shares will be affected by interest rate changes and the creditworthiness of issues held in the trust. Investing in high yield securities offers the potential for high current income and attractive total return, but involves certain risks. Lower-rated bond risks include default of the issuer and rising interest rates. Interest income from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. Lipper Inc., a widely respected data provider in the industry, calculates an average total return for mutual funds with similar investment objectives as those of the trust.

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 highest rating assigned to a particular bond by one of the following nationally-recognized rating agencies: Standard & Poor's Corporation, Moody's Investors Service, Inc. or Fitch Investors Service, Inc. Sector breakdowns are calculated as a percentage of net assets. Because the trust is actively managed, there can be no guarantee that the fund will continue to maintain this quality breakdown or invest in these sectors in the future. ABOUT DURATION Duration is a measure, expressed in years, of interest-rate sensitivity. It's similar to maturity, but because it takes into consideration the entire stream of future principal and interest payments and how long it will take to collect them, it is a more complex and also a more accurate measure of a trust's exposure to changing interest rates. Because we are active duration managers, we tend to use duration as a tactical tool to anticipate or respond to interest rate changes. Because bond prices move in the opposite direction that interest rates are moving, we lower duration when we expect interest rates to rise and we raise duration when we expect interest rates to fall. This adjustment provides the potential to benefit performance. If we are wrong and interest rates rise after we lengthen duration or fall after we shorten duration, fund performance could be hurt. 1 INVESTMENT PORTFOLIO November 30, 2002 MUNICIPAL BONDS - 97.2% PAR VALUE ------------------------------------------------------------- EDUCATION -

ACCOUNTING POLICIES ORGANIZATION: Colonial Investment Grade 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. The Trust's investment goal is to seek as high a level of after-tax total return as is consistent with prudent risk, by pursuing current income generally exempt from ordinary federal income tax and opportunities for long-term appreciation from a portfolio primarily invested in investment grade municipal bonds. The Trust is authorized to issue an unlimited number of common shares of beneficial interest and 2,400 Auction Preferred Shares ("APS"). The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 AND TRANSACTIONS: Debt securities generally are valued by a pricing service based upon market transactions for normal, institutional-size trading units of similar securities. When management deems it appropriate, an over-the-counter or exchange bid quotation is used. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded. Short-term obligations with a maturity of 60 days or less are valued at amortized cost. Investments for which market quotations are not readily available, or quotations which management believes are not appropriate, are valued at fair value under procedures approved by the Board of Trustees. Security transactions are accounted for on the date the securities are purchased, sold or mature. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes. The Trust may trade securities on other than normal settlement terms. 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. FEDERAL INCOME TAXES: Consistent with the Trust's policy to qualify as a regulated investment company and to distribute all of its taxable and tax-exempt income, no federal income tax has been accrued. INTEREST INCOME, DEBT DISCOUNT AND PREMIUM: Interest income is recorded on the accrual basis. Original issue discount is accreted to interest income over the life of the security with a corresponding increase in the cost basis. Premium is amortized against interest income with a corresponding decrease in the cost basis. Effective December 1, 2001, the Trust adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began accreting market discount on all debt securities. The cumulative effect of this accounting change did not impact total net assets of the Trust, but resulted in reclassifications as follows, based on securities held by the Trust on December 1, 2001: NET UNREALIZED COST APPRECIATION ------ -------------- $168,976 $(168,976) The effect of this change, for the year ended November 30, 2002, was as follows: NET INVESTMENT NET REALIZED NET UNREALIZED INCOME GAINS APPRECIATION ------ ------- ------------ $101,681 $(27,635) $(74,046) The Statement of Changes in Net Assets and Financial Highlights for prior periods have not been restated to reflect this change. DISTRIBUTIONS TO SHAREHOLDERS: Distributions to common shareholders are recorded on the ex-date. Distributions to preferred shareholders are recorded daily and are 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 November 30, 2002 was 1.24%. For the year ended November 30, 2002, the Trust declared dividends to Auction Preferred shareholders amounting to $870,588 representing an average APS dividend rate of 1.45%. NOTE 2. FEDERAL TAX INFORMATION Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. These differences are primarily due to differing treatments for discount accretion on debt securities, straddle deferrals, mark-to-market on futures contracts, current year distribution payable, capital loss carryforwards and non-deductible expenses. Reclassifications are made to the Trust's capital accounts to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. 11 NOTES TO FINANCIAL STATEMENTS (CONTINUED) For the year ended November 30, 2002, permanent items identified and reclassified among the components of net assets are as follows: UNDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN INCOME LOSS CAPITAL ------ ------- ------------ $(245) $245 $-- Net investment income, net realized gain (loss) and net assets were not affected by this reclassification. The tax character of distributions paid to common and APS shareholders during the year was as follows: TAX-EXEMPT ORDINARY INCOME INCOME ------------ ---------------- $88,367 $8,504,760 As of November 30, 2002, the components of distributable earnings on a tax basis were as follows: UNDISTRIBUTED TAX-EXEMPT UNREALIZED INCOME APPRECIATION ------------ ---------------- $1,228,626 $8,341,075 The following capital loss carryforwards are 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 ---------- ------------ 2003 $ 172,808 2004 1,454,485 2008 3,464,384 2010 1,238,884 ----------- $6,330,561 ----------- NOTE 3. FEES AND COMPENSATION PAID TO AFFILIATES MANAGEMENT FEE: Colonial Management Associates, Inc. (the "Advisor") is the investment advisor of the Trust and furnishes accounting and other services and office facilities for a fee to be paid monthly at the annual rate of 0.65% of the Trust's average weekly net assets, including assets applicable to the APS. PRICING AND BOOKKEEPING FEES: The Advisor is responsible for providing pricing and bookkeeping services to the Trust under a Pricing and Bookkeeping Agreement. Under a separate agreement (the "Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. Under its pricing and bookkeeping agreement with the Trust, the Advisor receives from the Trust an annual flat fee of $10,000, paid monthly, and in any month that the Trust's average weekly net assets, including assets applicable to the APS, are more than $50 million, a monthly fee equal to the average weekly net assets, including assets applicable to the APS, of the Trust for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement. For the year ended November 30, 2002, the net asset based fee rate was 0.036%. The Trust also pays out-of-pocket costs for pricing services. OTHER: The Trust pays no compensation to its officers, all of whom are employees of the Advisor or its affiliates. The Trust's Independent 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. The Trust has an agreement with its custodian bank under which $877 of custody fees were reduced by balance credits for the year ended November 30, 2002. 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. NOTE 4. PREFERRED SHARES The Trust currently has outstanding 2,400 APS. 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). 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 and in accordance with the guidelines prescribed by the 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 of the APS. At November 30, 2002, there were no such restrictions on the Trust. Under Emerging Issues Task Force ("EITF") promulgation Topic D-98, Classification and Measurement of Redeemable Securities, which was issued on July 19, 2001, preferred securities that are redeemable for cash or other assets are classified outside of permanent equity to the extent that the redemption is at a fixed or determinable price and at the option of the holder or upon the occurrence of an event that is not solely within the control of the issuer. Subject to the guidance of the EITF, the Trust's preferred shares, which were previously classified as a component of net assets, have been reclassified outside of permanent equity (net assets) in the accompanying financial statements. Prior year amounts have also been reclassified to conform with this presentation. The impact of this reclassification creates no change to the net assets available to common shareholders. 12 NOTES TO FINANCIAL STATEMENTS (CONTINUED) NOTE 5. PORTFOLIO INFORMATION INVESTMENT ACTIVITY: For the year ended November 30, 2002, purchases and sales of investments, other than short-term obligations, were $19,278,287 and $24,716,777, respectively. Unrealized appreciation (depreciation) at November 30, 2002, based on cost of investments for federal income tax purposes, was: Gross unrealized appreciation $ 13,415,076 Gross unrealized depreciation (5,259,532) ----------- Net unrealized appreciation $ 8,155,544 ----------- OTHER: The Trust had greater than 10% of its net assets at November 30, 2002, invested in issuers located in each of the following states; New York, Texas and Massachusetts. There are certain risks arising from geographic concentration in any state. Certain revenue or tax related events in a state may impair the ability of certain issuers of municipal securities to pay principal and interest on their obligations. The Trust may focus its investments in certain industries, subjecting it to greater risk than a trust that is more diversified. The Trust may invest in municipal and U.S. Treasury futures contracts and purchase and write options on futures. 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 and options 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 different trading hours, or the temporary absence of a liquid market, for either the instrument or the underlying securities or (3) an inaccurate prediction by the Advisor of the future direction of interest rates. Any of these risks may involve amounts exceeding the amount recognized 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 its custodian 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 payable or receivable and offset in unrealized gains or losses. The Trust recognizes a realized gain or loss when the contract is closed or expires. Refer to the Trust's Investment Portfolio for a summary of open futures contacts at November 30, 2002. 13 FINANCIAL HIGHLIGHTS Selected data for a share outstanding throughout each period is as follows (common shares unless otherwise stated): PERIOD YEAR ENDED NOVEMBER 30, ENDED YEAR ENDED DECEMBER 31, ----------------------------------- NOVEMBER 30, ------------------------ 2002 2001 2000 1999 (a) 1998 1997 --------------------------------------------------------------------------------------------------------------------------------- NET ASSET VALUE, BEGINNING OF PERIOD $ 11.06 $ 10.55 $ 10.31 $ 11.49 $ 11.43 $ 10.87 ------------ ----------- ----------- ------------ ----------- ---------- INCOME FROM INVESTMENT OPERATIONS: Net investment income 0.78(b)(c) 0.75(c) 0.81(d) 0.58 0.60 0.62 Net realized and unrealized gain (loss) on investments and futures contracts (0.05)(b) 0.52 0.27 (1.12) 0.07 0.58 ------------ ----------- ----------- ------------ ----------- ---------- Total from Investment Operations 0.73 1.27 1.08 (0.54) 0.67 1.20 ------------ ----------- ----------- ------------ ----------- ---------- LESS DISTRIBUTIONS DECLARED TO PREFERRED SHAREHOLDERS: From net investment income (0.08) (0.16) (0.22) (0.05) -- -- ------------ ----------- ----------- ------------ ----------- ---------- Total from Investment Operations Applicable to Common Shareholders 0.65 1.11 0.86 (0.59) 0.67 1.20 ------------ ----------- ----------- ------------ ----------- ---------- LESS DISTRIBUTIONS DECLARED TO COMMON SHAREHOLDERS: From net investment income (0.67) (0.60) (0.60) (0.52) (0.61) (0.64) In excess of net investment income -- -- -- -- --(e) -- ------------ ----------- ----------- ------------ ----------- ---------- Total Distributions Declared to Common Shareholders (0.67) (0.60) (0.60) (0.52) (0.61) (0.64) ------------ ----------- ----------- ------------ ----------- ---------- LESS SHARE TRANSACTIONS: Commission and offering costs-- preferred shares -- -- (0.02) (0.07) -- -- ------------ ----------- ----------- ------------ ----------- ---------- NET ASSET VALUE, END OF PERIOD $ 11.04 $ 11.06 $ 10.55 $ 10.31 $ 11.49 $ 11.43 ------------ ----------- ----------- ------------ ----------- ---------- Market price per share-- common shares $ 10.09 $ 10.87 $ 8.92 $ 9.06 $ 11.19 $ 10.56 ------------ ----------- ----------- ------------ ----------- ---------- Total return-- based on market value-- common shares (f) (1.10)% 29.28% 5.20% (14.64)%(g) 11.94% 10.76% ------------ ----------- ----------- ------------ ----------- ---------- RATIOS TO AVERAGE NET ASSETS/SUPPLEMENTAL DATA: Expenses (h)(i) 1.28% 1.28% 1.31% 1.03%(j) 0.77% 0.83% Net investment income before preferred stock dividend (h)(i) 7.06%(b) 6.80% 7.91% 5.75%(j) 5.24% 5.63% Net investment income after preferred stock dividend (h)(i) 6.38%(b) 5.38% 5.80% 5.26%(j) 5.24% 5.63% Portfolio turnover rate 10% 31% 23% 25%(g) 24% 21% Net assets, end of period (000's)-- common shares $ 127,050 $ 127,273 $ 121,366 $ 118,660 $ 132,242 $ 131,503 (a)The Trust changed its fiscal year end from December 31 to November 30.

These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Trust's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at November 30, 2002 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP Boston, Massachusetts January 20, 2003 16 UNAUDITED INFORMATION FEDERAL INCOME TAX INFORMATION 98.97% of the distributions from net investment income will be treated as exempt income for federal income tax purposes. 17 DIVIDEND REINVESTMENT PLAN COLONIAL INVESTMENT GRADE MUNICIPAL TRUST Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"), all shareholders whose shares are registered in their own names will have all distributions reinvested automatically in additional shares of the Trust by EquiServe Trust Company, N.A. (the "Plan Agent") unless a shareholder elects to receive cash. Shareholders whose shares are held in the name of a broker or nominee will have distributions reinvested automatically by the broker or nominee in additional shares under the Plan, unless the service is not provided by the broker or the nominee or the shareholder elects to receive distributions in cash. If the service is not available, such distributions will be paid in cash. Shareholders whose shares are held in the name of a broker or nominee should contact the broker or nominee for details. All distributions to shareholders who elect not to participate in the Plan will be paid by check mailed directly to the shareholder of record on the record date therefore by the Plan Agent as the dividend disbursing agent. Non-participants in the Plan will receive distributions in cash. Distributions payable to participants in the Plan will be applied by the Plan Agent, acting as agent for Plan participants, to the purchase of shares of the Trust. Such shares will be purchased by the Plan Agent at the then current market price of such shares in the open market, on the New York Stock Exchange or elsewhere, for the participants' accounts. 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 his 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 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 distributions. The Plan Agent's fees for the handling of the reinvestment of distributions will be paid by the Trust. Each participant in the Plan 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 distributions. Purchase orders from the participants in the Plan may be combined with those of other participants and the price paid by any particular participant may be the average of the price paid on various orders executed on behalf of groups of participants in the Plan. The automatic reinvestment of 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. All correspondence concerning the Plan should be directed to EquiServe Trust Company, N.A., by mail at P.O. Box 43010, Providence, RI 02940-3010, or by phone at 1-800-730-6001. 18 TRUSTEES The Trustees serve terms of indefinite duration.
