INVESTMENT RETURNS, NET ASSET VALUE (NAV) AND COMMON SHARE MARKET PRICE WILL FLUCTUATE AND TRUST SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. NAV per share is determined by dividing the value of the trust's portfolio securities, cash and other assets, less all liabilities and preferred shares, by the total number of common shares outstanding. The common share market price is the price the market is willing to pay for shares of the trust at a given time. Common share market price is influenced by a range of factors, including supply and demand and market conditions. Total return assumes an investment at the beginning of the period, reinvestment of all distributions for the period in accordance with the trust's dividend reinvestment plan, and sale of all shares at the end of the period. The Lehman Brothers Municipal Bond Index is a broad-based statistical composite of municipal bonds. The index does not include any expenses, fees or sales charges, which would lower performance. The index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. 1 Trust Report FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2006 MARKET CONDITIONS The economy continued to grow during the six-month period ended April 30, 2006, demonstrating some resiliency in the face of rising oil and other commodity prices, the Gulf Coast hurricanes, and emerging weakness in the housing market. This expansion was more modest in the final months of 2005, but gained considerable momentum in the first quarter. Against the backdrop of growth and good employment data, the Federal Open Market Committee (the "Fed") continued raising the federal funds target rate during the period, implementing four additional increases of 25 basis points each. These moves brought the target rate to 4.75 percent. The final hike of the period represented the fifteenth consecutive increase--the longest stretch of increases in 25 years. As the period came to a close, market observers speculated about the Fed's near-term intentions, given the central bank's view that although longer-term inflation currently appeared contained, commodity prices could amplify inflationary pressures. Returns across the municipal bond market varied significantly. As investors sought income opportunities, lower rated bonds outpaced investment-grade bonds by a wide margin. Long-term bonds earned the best returns, broadly speaking, while bonds in the three-to-seven year range posted the most muted gains. Municipal bond issuance was robust during the final months of 2005. (In fact, 2005 marked a record high for municipal bond volume.) The tide changed in 2006, however. As rising rates discouraged issuers from refinancing debt, national municipal issuance dropped by approximately 25 percent in the first four months of the year versus the same period in 2005. While supply ebbed, the market's appetite for municipal bonds remained strong, with particularly heavy demand from high yield municipal bond funds. 2 PERFORMANCE ANALYSIS The trust's return can be calculated based upon either the market price or the net asset value (NAV) of its shares. NAV per share is determined by dividing the value of the trust's portfolio securities, cash and other assets, less all liabilities and preferred shares, by the total number of common shares outstanding, while market price reflects the supply and demand for the shares. As a result, the two returns can differ, as they did during the reporting period. On both an NAV basis and a market price basis, the trust outperformed its benchmark index, the Lehman Brothers Municipal Bond Index. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2006 ------------------------------------------------------------- LEHMAN BROTHERS BASED ON BASED ON MUNICIPAL NAV MARKET PRICE BOND INDEX 2.66% 5.37% 1.56% ------------------------------------------------------------- Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. Investment return, net asset value and common share market price will fluctuate and trust shares, when sold, may be worth more or less than their original cost. See Performance Summary for additional performance information and index definition. The trust uses leverage to enhance its dividend to common shareholders. The trust borrows money at short-term rates through the issuance of preferred shares. The proceeds are reinvested in longer-term securities, taking advantage of the difference between short- and longer-term rates. The Fed's policy of raising interest rates throughout the period made the trust's borrowing activity more expensive, which reduced the benefits of the trust's leverage activities. We managed the trust according to our well-established "relative value" discipline. We used rigorous fundamental research to seek high quality securities that we believed had good liquidity and total return potential. (Liquid securities are those for which there is a robust market of purchasers and sellers.) We purchased bonds we believed to be attractively valued, and held them until they reached our return targets or until we found bonds that offered more compelling prospects. Throughout the period, we sought opportunities to enhance the trust's yield, while adhering to our quality-driven criteria. We pared exposure to AAA rated securities and increased the trust's allocation to relatively higher yielding tiers of the investment-grade market. The trust considerably bolstered its stake in BBB rated credits; as of the end of the reporting period, these represented approximately 14 percent of bonds. Tobacco revenue issues were notable among these purchases. Our confidence in tobacco bonds was underpinned by the strong fundamentals of the tobacco industry as well as by an improving litigation climate for tobacco companies. The trust was also well served by the addition of higher yielding hospital bonds rated single A and BBB. 3 We structured the portfolio to reflect our opinion that interest rates would continue to rise, with short-term rates rising more rapidly than long-term rates. To mitigate the trust's sensitivity to changing interest rates, we positioned the trust's duration to be shorter than its benchmark's. (Duration is a measure of interest rate sensitivity.) Reflecting our belief that the long-term segment of the bond market would offer the strongest performance, our purchases emphasized issues with maturities of 20 years and longer. Where possible, we favored bonds with defensive characteristics, such as pricing to shorter calls. Meanwhile, sales included zero-coupon bonds with a variety of maturities. (Zero-coupon bonds tend to underperform during periods of rising interest rates.) We pared positions in pre-refunded issues with maturities of 10 years or less, particularly emphasizing those with maturities of five years or less. Within the longer-term portion of the portfolio, we found opportunities for relative value trading. The trust remained well diversified across the major sectors of the municipal bond market, with a bias toward essential services. As of the close of the reporting period, the trust's largest allocations were hospital and general purpose sectors, followed by public education issues. The trust's bond holdings were invested in investment grade holdings, with credits rated AA or above accounting for approximately 75 percent of bond assets. VGM's procedure for reinvesting all dividends and distributions in common shares is through purchases in the open market. This method helps support the market value of the Trust's shares. In addition, we would like to remind you that the Trustees have approved a procedure whereby the Trust may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase. There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the trust in the future. 4 RATINGS ALLOCATION AS OF 4/30/06 AAA/Aaa 69.6% AA/Aa 4.9 A/A 9.1 BBB/Baa 14.0 BB/Ba 0.4 B/B 0.2 Non-Rated 1.8 TOP FIVE SECTORS AS OF 4/30/06 Hospital 15.0% General Purpose 12.9 Public Education 8.5 Airports 7.2 Wholesale Electric 6.5 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 4/30/06 California 15.5% New York 11.8 Texas 8.9 Illinois 7.1 Florida 5.3 New Jersey 4.5 South Carolina 4.1 Michigan 3.4 North Carolina 3.2 Arizona 2.9 Washington 2.8 Colorado 2.6 Georgia 2.5 Indiana 2.0 Nevada 2.0 Pennsylvania 1.9 Iowa 1.4 Alabama 1.4 Tennessee 1.3 Oregon 1.3 Louisiana 1.2 Minnesota 1.2 Massachusetts 1.1 Ohio 1.0 Maryland 0.9 Alaska 0.8 Virginia 0.7 Connecticut 0.7 Kentucky 0.7 Missouri 0.7 District of Columbia 0.6 Oklahoma 0.6 Guam 0.5 Puerto Rico 0.5 Wisconsin 0.5 (continued on next page) 5 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 4/30/06 (continued from previous page) South Dakota 0.4 Kansas 0.4 West Virginia 0.4 Vermont 0.2 New Hampshire 0.2 Wyoming 0.2 Mississippi 0.1 Arkansas 0.1 New Mexico 0.1 Montana 0.1 Utah 0.1 North Dakota 0.1 ----- Total Investments 100.0% ----- Subject to change daily.

See Notes to Financial Statements 33 VAN KAMPEN TRUST FOR INVESTMENT GRADE MUNICIPALS NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) 1. SIGNIFICANT ACCOUNTING POLICIES Van Kampen Trust for Investment Grade Municipals (the "Trust") is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Trust's investment objective is to seek to provide a high level of current income exempt from federal income tax, consistent with preservation of capital. The Trust will invest substantially all of its assets in municipal securities rated investment grade at the time of investment. The Trust commenced investment operations on January 24, 1992. The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Trust may purchase and sell securities on a "when-issued" or "delayed delivery" basis with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Trust will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At April 30, 2006, the Trust had $2,670,000 of when-issued or delayed delivery purchase commitments. C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. The Trust intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset such losses against any future realized capital gains. During the prior fiscal year, the Trust utilized capital losses carried forward of $1,444,681. 34 VAN KAMPEN TRUST FOR INVESTMENT GRADE MUNICIPALS NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) continued At April 30, 2006, the cost and related gross unrealized appreciation and depreciation are as follows: Cost of investments for tax purposes........................ $1,088,258,988 ============== Gross tax unrealized appreciation........................... $ 50,822,511 Gross tax unrealized depreciation........................... (2,385,028) -------------- Net tax unrealized appreciation on investments.............. $ 48,437,483 ============== E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly dividends from net investment income to common shareholders. Net realized gains, if any, are distributed annually on a pro rata basis to common and preferred shareholders. Distributions from net realized gains for book purposes may include short-term capital gains and a portion of futures gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended October 31, 2005 was as follows: Distributions paid from: Ordinary income........................................... $ 96,040 Tax exempt income......................................... 32,252,093 Long-term capital gain.................................... -0- ----------- $32,348,133 =========== As of October 31, 2005, the components of distributable earnings on a tax basis were as follows: Undistributed ordinary income............................... $ 105,209 Undistributed tax exempt income............................. 1,778,426 Undistributed long-term capital gain........................ 13,213,377 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Asset Management (the "Adviser") provides investment advice and facilities to the Trust for an annual fee payable monthly of .55% of the average daily net assets of the Trust. For the six months ended April 30, 2006, the Trust recognized expenses of approximately $38,300, representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Trust is a partner of such firm and he and his law firm provide legal services as legal counsel to the Trust. Under separate Legal Services, Accounting Services and Chief Compliance Officer (CCO) Employment agreements, the Adviser provides accounting and legal services and the CCO provides compliance services to the Trust. The costs of these services are allocated to each trust. For the six months ended April 30, 2006, the Trust recognized expenses of approximately $62,000, representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Trust, as well as, the salary, benefits and related costs of the CCO and related support staff paid by Van Kampen. Services provided pursuant to the Legal Services agreement are reported as part of "Legal" expenses on the Statement of Operations. Services provided pursuant to the 35 VAN KAMPEN TRUST FOR INVESTMENT GRADE MUNICIPALS NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) continued Accounting Services and CCO Employment agreement are reported as part of "Other" expenses on the Statement of Operations. Certain officers and trustees of the Trust are also officers and directors of Van Kampen. The Trust does not compensate its officers or trustees who are also officers of Van Kampen. The Trust provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation to a later date. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Trust. The maximum annual benefit per trustee under the plan is $2,500. 3. CAPITAL TRANSACTIONS For the six months ended April 30, 2006 and the year ended October 31, 2005, transactions in common shares were as follows: SIX MONTHS ENDED YEAR ENDED APRIL 30, 2006 OCTOBER 31, 2005 Beginning Shares........................................ 43,799,086 27,013,149 Shares Issued Through Merger............................ -0- 16,785,937 ---------- ---------- Ending Shares........................................... 43,799,086 43,799,086 ========== ========== On October 7, 2005, the Trust acquired all of the assets and liabilities of the Van Kampen Municipal Income Trust (ticker symbol VMT) through a tax free reorganization approved by VMT shareholders on September 23, 2005. The Trust issued 16,785,937 common shares with a net asset value of $285,697,964 and 6,600 Auction Preferred Shares (APS) with a liquidation value of $165,000,000, in exchange for VMT net assets. The shares of VMT were converted into Trust shares at a ratio of 0.585182 to 1 and 1 to 20, for common shares and APS, respectively. Net unrealized appreciation on VMT as of October 7, 2005 was $20,734,270. The Trust assumed VMT's book to tax accretion differences, which resulted in a $404,784 increase to accumulated undistributed net investment income and a corresponding decrease to net unrealized appreciation. Combined net assets applicable to common shares on the day of reorganization were $745,337,328 and net assets including preferred shares were $1,175,337,328. Included in these net assets was a Trustees deferred compensation balance of $255,898 and Trustees retirement plan balance of $74,816 which are included in accumulated undistributed net investment income. Also, included in these net assets were losses recognized for tax purposes on open futures transactions at October 7, 2005 of $561,213 which is included in accumulated net realized gain. 4. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $175,122,998 and $179,430,214, respectively. 5. DERIVATIVE FINANCIAL INSTRUMENTS A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index. 36 VAN KAMPEN TRUST FOR INVESTMENT GRADE MUNICIPALS NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) continued In order to seek to manage the interest rate exposure of the Trust's portfolio in a changing interest rate environment, the Trust may purchase or sell financial futures contracts or engage in transactions involving interest rate swaps, caps, floors or collars. The Trust expects to enter into these transactions primarily as a hedge against anticipated interest rate or fixed-income market changes, for duration management or for risk management purposes, but may also enter into these transactions to generate additional income. All of the Trust's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. Summarized below are the specific types of derivative financial instruments used by the Trust. A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Trust generally invests in exchange traded futures contracts on U.S. Treasury Bonds and Notes and typically closes the contract prior to the delivery date. Upon entering into futures contracts, the Trust maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to the rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended April 30, 2006, were as follows: CONTRACTS Outstanding at October 31, 2005............................. 2,572 Futures Opened.............................................. 5,483 Futures Closed.............................................. (6,874) ------ Outstanding at April 30, 2006............................... 1,181 ====== B. INDEXED SECURITY An inverse floating rate security is one where the coupon is inversely indexed to a short-term floating interest rate multiplied by a specific factor. As the floating rate rises, the coupon is reduced. Conversely, as the floating rate declines, the coupon is increased. The price of these securities may be more volatile than the price of a comparable fixed rate security. These instruments are typically used by the Trust to enhance the yield of the portfolio. These instruments are identified in the portfolio of investments. C. INTEREST RATE SWAPS The Trust may enter into interest rate swaps primarily to preserve a return or spread on a particular investment or portion of its portfolio, as a duration management technique or to protect against any increase in the price of securities the Trust 37 VAN KAMPEN TRUST FOR INVESTMENT GRADE MUNICIPALS NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) continued anticipates purchasing at a later date. Interest rate swaps are contractual agreements to exchange periodic interest payment streams calculated on a predetermined notional principal amount. Interest rate swaps generally involve one party paying a fixed interest rate and the other party paying a variable rate. The Trust will usually enter into swaps on a net basis, i.e., the two payment streams are netted out in a cash settlement on the payment date or dates specified in the instrument, with the Trust receiving or paying, as the case may be, only the net amount of the two payments. The Trust accrues the net amount with respect to each swap on a daily basis. This net amount is recorded within unrealized appreciation/ depreciation on swap contracts. Upon cash settlement of the periodic payments, the net amount is recorded as realized gain/loss on swap contracts on the Statement of Operations. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. If there is a default by the counterparty, the Trust will have contractual remedies pursuant to the agreements related to the transaction. 6. PREFERRED SHARES The Trust has outstanding 17,200 APS in seven series. Series A, B, and C contain 3,000 shares each, Series D contains 1,600 shares and Series E, F and G contain 2,200 shares each. Dividends are cumulative and the dividend rates are generally reset every 28 days through an auction process. The average rate in effect on April 30, 2006 was 3.616%. During the six months ended April 30, 2006, the rates ranged from 2.590% to 5.750%. The Trust pays annual fees equivalent to .25% of the preferred share liquidation value for the remarketing efforts associated with the preferred auctions. These fees are included as a component of "Preferred Share Maintenance" expense on the Statement of Operations. The APS are redeemable at the option of the Trust in whole or in part at the liquidation value of $25,000 per share plus accumulated and unpaid dividends. The Trust is subject to certain asset coverage tests and the APS are subject to mandatory redemption if the tests are not met. 7. INDEMNIFICATIONS The Trust enters into contracts that contain a variety of indemnifications. The Trust's maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 38 VAN KAMPEN TRUST FOR INVESTMENT GRADE MUNICIPALS BOARD OF TRUSTEES, OFFICERS AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.
