INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND TRUST SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The 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. 1 Trust Report FOR THE SIX-MONTH PERIOD ENDED JANUARY 31, 2007 MARKET CONDITIONS Solid economic growth, contained inflation, and falling oil and commodity prices created a favorable environment for senior loans during the six-month reporting period. Overall trends in the credit markets remained positive as corporations exhibited strong cash flows and balance sheets, increased productivity, and improved credit quality while benefiting from a generally lower cost of capital. In addition, corporate debt default rates remained low. The Federal Open Market Committee (the "Fed") finally took a respite from its two-year long campaign of raising interest rates during the reporting period, electing to keep its target federal funds rate unchanged at 5.25 percent. The ease in the Fed's monetary policy, however, had been widely anticipated by the market and interest rates had already declined in response. As a result, interest rates across the yield curve remained relatively stable throughout the period. Yields on senior loans, which adjust in tandem to short-term rates, were generally unchanged as well. Yield spreads in the senior loan market climbed to late-2005 levels in the third quarter of 2006, then leveled off until the last month of the period, when they narrowed slightly. Demand for senior loans remained quite strong as the market continues to see increasing activity from institutional investors such as hedge funds and propriety desks, as well as from crossover investments from traditional high-yield investors. The strong demand for senior loans was met by robust supply. A significant increase in merger and acquisition activity, leveraged buyouts, and second lien loans helped fuel record levels of new issuance. At the same time, senior loan default rates receded throughout the period, reaching a record low of just 0.78 percent. 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. For the six months ended January 31, 2007, the trust returned 10.60 percent on a market price basis and 4.50 percent on an NAV basis. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED JANUARY 31, 2007 -------------------------------------------------- BASED ON NAV BASED ON MARKET PRICE 4.50% 10.60% -------------------------------------------------- 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. We continued to follow our research-intensive investment process focused on identifying companies with strong management, solid and predictable cash flow, and sufficient collateral in the event of default. We employ a bottom-up asset selection process driven by analysis of individual company fundamentals. We also analyze overall sector and industry trends, which led us to favor loans in sectors that are typically less cyclical in nature, such as food and drug, cable, and leisure and entertainment. These sectors continued to be represented in the trust's top holdings. We also favored less cyclical names in the paper and packaging sector that have experienced steady demand. Throughout the reporting period, however, the portfolio was invested in broad range of industries. We generally avoid investing in companies that we perceive to be vulnerable to cyclical economic downturns. As such, we remain cautious regarding the auto and airline industries due to their susceptibility to high fuel prices. The trust benefited during the period from our use of leverage. Leverage involves borrowing at a floating short-term rate and reinvesting the proceeds at a higher rate. We used this strategy on an ongoing basis in an effort to enhance the trust's dividend. Unlike other fixed-income asset classes, using leverage in conjunction with senior loans does not involve the same degree of risk from rising short-term interest rates since the income from senior loans adjusts to changes in interest rates, as do the rates which determine the trust's borrowing costs. (Similarly, should short-term rates fall, borrowing costs would also decline.) We might reduce leverage in periods of weaker credit quality conditions to prevent magnifying erosion of the trust's net asset value. 3 The trust'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 SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 1/31/2007 Healthcare 7.4% Printing & Publishing 6.9 Broadcasting-Cable 6.7 Beverage, Food & Tobacco 6.1 Entertainment & Leisure 6.1 Chemicals, Plastics & Rubber 6.0 Automotive 5.0 Electronics 4.0 Buildings & Real Estate 3.4 Utilities 3.0 Business Equipment & Services 3.0 Ecological 2.5 Aerospace/Defense 2.4 Containers, Packaging & Glass 2.4 Hotels, Motels, Inns & Gaming 2.2 Finance 2.1 Construction Material 2.1 Paper & Forest Products 2.1 Personal & Miscellaneous Services 1.8 Diversified Manufacturing 1.6 Insurance 1.6 Retail-Stores 1.6 Broadcasting-Radio 1.5 Non-Durable Consumer Products 1.4 Health & Beauty 1.4 Restaurants & Food Service 1.3 Natural Resources 1.2 Medical Products & Services 1.2 Telecommunications-Wireless 1.0 Textiles & Leather 1.0 Home & Office Furnishings, Housewares & Durable Consumer Products 0.9 Telecommunications-Local Exchange Carriers 0.9 Retail-Specialty 0.9 Machinery 0.9 Pharmaceuticals 0.8 Mining, Steel, Iron & Non-Precious Metals 0.6 Education & Child Care 0.5 Farming & Agriculture 0.5 Grocery 0.4 Transportation-Rail Manufacturing 0.4 Banking 0.4 Transportation-Cargo 0.4 Retail-Office Products 0.3 Telecommunications-Long Distance 0.3 Broadcasting-Television 0.2 Telecommunications-Equipment & Services 0.2 Broadcasting-Diversified 0.2 Durable Consumer Products 0.1 Retail-Oil & Gas 0.1 Food Products 0.1 (continued on next page) 5 SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 1/31/2007 (continued from previous page) Transportation-Personal 0.1 Tobacco 0.0* ----- Total Long-Term Investments 99.2% Short-Term Investments 0.8 ----- Total Investments 100.0% * Amount is less than 0.1% Subject to change daily.

Because of these mandatory prepayment conditions and because there may be significant economic incentives for a Borrower to prepay, prepayments of Senior Loans in the Trust's portfolio may occur. As a result, the actual remaining maturity of Senior Loans held in the Trust's portfolio may be substantially less than the stated maturities shown. Although the Trust is unable to accurately estimate the actual remaining maturity of individual Senior Loans, the Trust estimates that the actual average maturity of the Senior Loans held in its portfolio will be approximately 18-24 months. ** Senior Loans in which the Trust invests generally pay interest at rates which are periodically redetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the London Inter-Bank Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more major United States banks and (iii) the certificate of deposit rate. Senior Loans are generally considered to be restricted in that the Trust ordinarily is contractually obligated to receive approval from the Agent Bank and/or Borrower prior to the disposition of a Senior Loan.

N/A=Not Applicable See Notes to Financial Statements 39 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2007 (UNAUDITED) 1. SIGNIFICANT ACCOUNTING POLICIES Van Kampen Senior Income Trust (the "Trust") is registered as a non-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, consistent with preservation of capital. The Trust seeks to achieve its objective by investing primarily in a portfolio of interests in floating or variable rate senior loans to corporations, partnerships and other entities which operate in a variety of industries and geographical regions. The Trust borrows money for investment purposes which will create the opportunity for enhanced return, but also should be considered a speculative technique and may increase the Trust's volatility. The Trust commenced investment operations on June 24, 1998. 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 The Trust's Senior Loans and notes are valued by the Trust following valuation guidelines established and periodically reviewed by the Trust's Board of Trustees. Under the valuation guidelines, Senior Loans and notes for which reliable market quotes are readily available are valued at the mean of such bid and ask quotes. Where reliable market quotes are not readily available, Senior Loans and notes are valued, where possible, using independent market indicators provided by independent pricing sources approved by the Board of Trustees. Other Senior Loans and notes are valued by independent pricing sources approved by the Board of Trustees based upon pricing models developed, maintained and operated by those pricing sources or valued by Van Kampen Asset Management (the "Adviser") by considering a number of factors including consideration of market indicators, transactions in instruments which the Adviser believes may be comparable (including comparable credit quality, interest rate, interest rate redetermination period and maturity), the credit worthiness of the Borrower, the current interest rate, the period until next interest rate redetermination and the maturity of such Senior Loan. Consideration of comparable instruments may include commercial paper, negotiable certificates of deposit and short-term variable rate securities which have adjustment periods comparable to the Senior Loans in the Trust's portfolio. The fair value of Senior Loans are reviewed and approved by the Trust's Valuation Committee and the Board of Trustees. Credit default swaps are valued using market quotations from brokers. Equity securities are valued on the basis of prices furnished by pricing services or as determined in good faith by the Adviser under the direction of the Board of Trustees. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. Short-term loan participations are valued at cost in the absence of any indication of impairment. The Trust may invest in repurchase agreements, which are short-term investments in which the Trust acquires ownership of a debt security and the seller agrees to repurchase the security at a future time and specified price. Repurchase agreements are fully collateralized by 40 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2007 (UNAUDITED) continued the underlying debt security. The Trust will make payment for such securities only upon physical delivery or evidence of book entry transfer to the account of the custodian bank. The seller is required to maintain the value of the underlying security at not less than the repurchase proceeds due the Trust. B. SECURITY TRANSACTIONS Investment transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. Legal expenditures that are expected to result in the restructuring of or a plan of reorganization for an investment are recorded as realized losses. 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 January 31, 2007, the Trust had no when-issued or delayed delivery purchase commitments. C. INVESTMENT INCOME Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Facility fees received are treated as market discounts. Market premiums are amortized and discounts are accreted over the stated life of each applicable senior loan, note, or other fixed income security. Other income is comprised primarily of amendment fees which are recorded when received. Amendment fees are earned as compensation for agreeing to changes in loan agreements. 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. At July 31, 2006, the Trust had an accumulated capital loss carryforward for tax purposes of $218,138,489, which will expire according to the following schedule.

DISTRIBUTION OF INCOME AND GAINS The Trust intends to declare and pay monthly dividends from net investment income to common shareholders. Net realized gains, if any, are distributed at least annually to common shareholders. Distributions from net realized gains for book purposes may include short term capital gains, which are included as ordinary income for tax purposes. The tax character of distributions paid for the year ended July 31, 2006 were as follows: Distributions paid from: Ordinary income........................................... $141,121,769 Long-term capital gain.................................... -0- ------------ $141,121,769 ============ As of July 31, 2006, the components of distributable earnings on a tax basis were a follows: Undistributed ordinary income............................... $6,082,285 Net realized gains or losses may differ for financial reporting and tax purposes primarily as a result of the deferral of losses resulting from wash sale transactions. 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Trust's Investment Advisory Agreement, the Adviser will provide investment advice and facilities to the Trust for an annual fee of .85% of the average daily managed assets. Managed assets are defined as the gross asset value of the Trust minus the sum of accrued liabilities, other than the aggregate amount of borrowings undertaken by the Trust. In addition, the Trust will pay a monthly administrative fee to Van Kampen Investments Inc., the Trust's Administrator, at an annual rate of .20% of the average daily managed assets of the Trust. The administrative services provided by the Administrator include monitoring the provisions of the loan agreements and any agreements with respect to participations and assignments, record keeping responsibilities with respect to interests in Variable Rate Senior Loans in the Trust's portfolio and providing certain services to the holders of the Trust's securities. For the six months ended January 31, 2007, the Trust recognized expenses of approximately $102,800 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 and Chief Compliance Officer (CCO) Employment agreements, the Adviser provides 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 January 31, 2007, the Trust recognized expenses of approximately $60,900 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing 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 "Professional Fees" on the Statement of Operations. Services provided pursuant to the CCO Employment agreement are reported as part of "Accounting and Administrative Expenses" on the Statement of Operations. 42 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2007 (UNAUDITED) continued 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 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. During the period, the Trust owned shares of the following affiliated companies. Affiliated companies are defined by the 1940 Act, as amended, as those companies in which a fund holds 5% or more of the outstanding voting securities. DIVIDEND/ MARKET PAR/ INTEREST VALUE NAME SHARES* INCOME 1/31/07 COST Neoplan USA Corp., Revolving Credit Agreement.................................. $933,750 -0- $873,056 $ 933,750 Neoplan USA Corp., Common Stock.............. 8,517 -0- -0- 85 Neoplan USA Corp., Preferred Stock C......... 532 -0- -0- 532 Neoplan USA Corp., Preferred Stock D......... 1,730 -0- -0- 1,073,989 --------- -------- ---------- -0- $873,056 $2,008,356 ========= ======== ========== * Shares were acquired through the restructuring of Senior Loan interests. There were no affiliate transactions during the six months ended January 31, 2007. 3. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from investments sold and repaid, excluding short-term investments, were $1,030,200,089 and $981,414,286, respectively. 4. COMMITMENTS Pursuant to the terms of certain Senior Loan agreements, the Trust had unfunded loan commitments of approximately $98,729,300 as of January 31, 2007. The Trust intends to reserve against such contingent obligations by designating cash, liquid securities and liquid Senior Loans as a reserve. The unrealized depreciation on these commitments of $1,406,231 as of January 31, 2007 is reported as "Unfunded Commitments" on the Statement of Assets and Liabilities. 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. The Trust may use derivative instruments for a variety of reasons, such as to attempt to protect the Trust against possible changes in the market value of its portfolio or to generate potential gain. 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. The Trust may enter into credit default swap contracts for hedging purposes or to gain exposure to a credit in which the Trust may otherwise invest. A credit default swap is an agreement between two parties to exchange the credit risk of an issuer. A buyer of a credit 43 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2007 (UNAUDITED) continued default swap is said to buy protection by paying periodic fees in return for a contingent payment from the seller if the issuer has a credit event such as bankruptcy, a failure to pay outstanding obligations or deteriorating credit while the swap is outstanding. A seller of a credit default swap is said to sell protection and thus collects the periodic fees and profits if the credit of the issuer remains stable or improves while the swap is outstanding but the seller in a credit default swap contract would be required to pay an agreed-upon amount, which approximates the notional amount of the swap as disclosed in the table following the Portfolio of Investments, to the buyer in the event of an adverse credit event of the issuer. The Trust accrues for the periodic fees on swap contracts on a daily basis with the net amount accrued recorded within unrealized appreciation/depreciation of swap contracts. Upon cash settlement of the periodic fees, the net amount is recorded as realized gain/loss on swap contracts on the Statements of Operations. Net unrealized gains are recorded as an asset or net unrealized losses are reported as a liability on the Statement of Assets and Liabilities. The change in value of the swap contracts is reported as unrealized gains or losses on the Statement of Operations. Credit default swaps may involve greater risks than if the Trust had invested in the issuer directly. Credit default swaps are subject to general market risk, counterparty risk and credit risk. If there is a default by the counterparty, the Trust will have contractual remedies pursuant to the agreements related to the transaction. 6. SENIOR LOAN PARTICIPATION COMMITMENTS The Trust invests primarily in participations, assignments, or acts as a party to the primary lending syndicate of a Variable Rate Senior Loan interest to United States and foreign corporations, partnerships, and other entities. When the Trust purchases a participation of a Senior Loan interest, the Trust typically enters into a contractual agreement with the lender or other third party selling the participation, but not with the borrower directly. As such, the Trust assumes the credit risk of the borrower, selling participant or other persons interpositioned between the Trust and the borrower. At January 31, 2007, the following sets forth the selling participants with respect to interests in Senior Loans purchased by the Trust on a participation basis. PRINCIPAL AMOUNT VALUE SELLING PARTICIPANT (000) (000) General Electric Capital Corp. ............................. $5,000 $5,017 7. BORROWINGS The Trust may utilize financial leverage to the maximum extent allowable under the 1940 Act, as amended. Under the 1940 Act, as amended, a Trust generally may not (i) borrow money greater than 33 1/3% of the Trust's total assets or (ii) issue preferred shares greater than 50% of the Trust's total assets. In using a combination of borrowing money and issuing preferred shares, the maximum allowable leverage is somewhere between 33 1/3% and 50% (but in no event more than 50%) of the Trust's total assets based on the relative amounts borrowed or preferred shares issued. The Trust has entered into a $700 million revolving credit and security agreement. Annual commitment fees of .13% are charged on the unused portion of the credit line. This 44 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2007 (UNAUDITED) continued revolving credit agreement is secured by the assets of the Trust. For the six months ended January 31, 2007, the average daily balance of borrowings under the revolving credit agreement was $555,483,696 with a weighted average interest rate of 5.20%. 8. PREFERRED SHARES ISSUANCE The Trust has outstanding 5,600 shares each of Series M, Series T, Series W, Series TH and Series F Auction Preferred Shares (APS), $.01 Par Value, $25,000 liquidation preference, for a total issuance of $700 million. Dividends are cumulative and the dividend rates are generally reset every seven days through an auction process. The average rate in effect on January 31, 2007 was 5.040%. During the six months ended January 31, 2007, the rates ranged from 4.900% to 5.350%. 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 the "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. 9. 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. 10. ACCOUNTING PRONOUNCEMENTS In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes--an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Recent SEC guidance allows implementing FIN 48 in the trust NAV calculations as late as the trust's last NAV calculation in the first required financial statement period. As a result, the Trust will incorporate FIN 48 in its semi annual report on January 31, 2008. The impact to the Trust's financial statements, if any, is currently being assessed. In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Trust's financial statement disclosures. 45 VAN KAMPEN SENIOR INCOME TRUST BOARD OF TRUSTEES, OFFICERS AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.
