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, 2006 MARKET CONDITIONS During the six-month period ended January 31, 2006, positive economic and corporate trends created a favorable backdrop for the senior loan asset class. The Gulf Coast hurricanes did not dampen the U.S. economy to the extent some had expected, nor did high oil prices and struggles of the auto industry. Inflation remained largely contained. By and large, corporations posted good profits, reflecting on-track business strategies, increasing revenues, strengthening balance sheets and improving credit quality. Despite some well publicized exceptions, corporate debt default rates remained low overall. These influences stoked ongoing demand for senior loans, from institutional and individual investors alike. Moreover, the adjustable-rate characteristics of senior loans proved particularly beneficial during the period. Because the yields of senior loans adjust in tandem to changes in short-term interest rates, the asset class was well positioned as interest rates rose across the short- and intermediate-term portions of the bond market. The strong demand for senior loans was met by robust supply in both the primary and secondary markets. Merger-and-acquisition activity, leveraged buyouts (private-to-public transactions), sponsor-driven dividend loans and second lien loans were among the activities spurring issuance. In this environment, yield spreads in the senior loan market held steady. 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, 2006, the trust returned 2.93 percent on a market price basis and 3.45 percent on an NAV basis. TOTAL RETURN FOR THE SIX-MONTH PERIOD ENDED JANUARY 31, 2006 ------------------------------------------------ BASED ON NAV BASED ON MARKET PRICE 3.45% 2.93% ------------------------------------------------ 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 believe that the rigor of our approach and our experience in the senior loan market were principal drivers of the trust's performance for the period. We managed the trust according to our research-intensive, time-tested approach, seeking to balance yield with a stable net asset value. Our investment process focused on identifying companies that we believed had strong management, solid and predictable cash flows, and sufficient collateral in the event of default. Consistent with our dedication to risk management, we diversified the portfolio broadly across the senior loan market. We followed a bottom-up security selection process, with investment decisions driven principally by our analysis of individual company fundamentals. That said, the portfolio construction process also included our comprehensive analysis of larger industry and sector trends. Notably, the trust's positioning reflected a defensive tilt throughout the period. Our criteria led us to favor senior loans in sectors that typically provide stable performance throughout an economic cycle. For example, the trust includes debt issued by food, drug and beverage companies, cable broadcasters, and leisure companies. These companies have historically enjoyed steady day-to-day demand for goods and services. The trust also included holdings in the defense industry; these issuers were well positioned to benefit from long-term demand trends, and held extensive hard assets as loan collateral. In contrast, we avoided companies we believed to be especially susceptible to cyclical economic downturns or rising fuel prices. We were particularly circumspect in regard to the highly leveraged auto and airline industries. This prudence served the trust well during the period. We were extremely cautious about the health care sector as well, based on concerns that an uncertain 3 regulatory environment and Medicaid reduction initiatives could create ongoing turbulence for the sector. The trust benefited during the period from our use of leverage. Leverage involves borrowing at a short-term lending 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 with other fixed-income 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. There is no guarantee that any sectors mentioned will continue to perform well or that securities in such sectors will be held by the trust in the future. CHANGES TO INVESTMENT POLICIES At a meeting held on March 1, 2006, the Board of Trustees approved changes to certain of the Trust's investment policies in order to expand the investment options available to the Trust as the Trust seeks to achieve its investment objective of high level of current income, consistent with preservation of capital. The Trust's investment policy of investing at least 80% of its total assets in Senior Loans remains unchanged. The changes to the Trust's investment policies are as follows: (1) The Trust may, subject to the limits specified below, invest in credit-linked deposits. Credit-linked deposits are deposits by lenders, such as the Trust, to support the issuance of letters of credit to the Senior Loan borrower. The Trust receives from the bank issuing such letters of credit an agreed upon rate of return in exchange for its deposit. There are risks associated with credit-linked deposits, including the credit risk of the bank which maintains the deposit account as well as the credit risk of the borrower. The Trust bears the risk of possible loss of its principal investment, in addition to the periodic interest payments that are expected to be received for the duration of the Trust's investment in the credit-linked deposit. Thus, restating the Trust's investment policies to include this new investment: The Trust may invest up to 20% of its total assets in any combination of (1) warrants and equity securities, in each case the Trust must own or acquire a Senior Loan of the same issuer, (2) junior debt securities or securities with a lien on collateral lower than a senior claim on collateral, (3) high quality short-term debt securities, (4) credit-linked deposits and (5) Treasury Inflation Protected Securities ("U.S. TIPS") and other inflation-indexed bonds issued by the U.S. government, its agencies or instrumentalities. (2) The Trust's ability to invest in structured products has been increased to 10% of its total assets and expanded to include credit default swaps ("CDS") to enhance the yield on its portfolio or to increase income available for 4 distributions or for other non-hedging purposes. A CDS is an agreement between two parties to exchange the credit risk of a particular issuer or reference entity. In a CDS transaction, a buyer pays periodic fees in return for a payment by the seller which is contingent upon an adverse credit event occurring in the underlying issuer or reference entity. The seller collects periodic fees from the buyer and profits if the credit of the underlying issuer or reference entity remains stable or improves while the swap is outstanding, but the seller in a CDS contract would be required to pay an agreed upon amount to the buyer in the event of an adverse credit event in the reference entity. A buyer of a CDS is said to buy protection whereas a seller of a CDS is said to sell protection. When the Trust buys a CDS, it is utilizing the swap for hedging purposes similar to other hedging strategies described herein. When the Trust sells a CDS, it is utilizing the swap to enhance the yield on its portfolio to increase income available for distribution or for other non-hedging purposes, and the Trust is subject to the 10% limitation described herein on structured products. 5 SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 1/31/2006 Beverage, Food & Tobacco 6.9% Broadcasting--Cable 6.6 Printing & Publishing 6.2 Entertainment & Leisure 6.1 Hotels, Motels, Inns & Gaming 5.9 Chemicals, Plastics & Rubber 5.7 Healthcare 5.2 Automotive 4.7 Electronics 4.4 Containers, Packaging & Glass 4.0 Buildings & Real Estate 4.0 Ecological 3.0 Medical Products & Services 2.8 Aerospace/Defense 2.7 Finance 2.6 Natural Resources 2.6 Utilities 2.2 Insurance 1.8 Healthcare & Beauty 1.7 Construction Material 1.6 Telecommunications--Local Exchange Carriers 1.6 Personal & Miscellaneous Services 1.5 Pharmaceuticals 1.4 Restaurants & Food Service 1.3 Diversified Manufacturing 1.3 Home & Office Furnishings, Housewares & Durable Consumer Products 1.2 Telecommunications--Wireless 1.1 Machinery 1.0 Retail--Specialty 1.0 Mining, Steel, Iron & Non-Precious Metals 0.9 Retail--Stores 0.8 Retail--Oil & Gas 0.7 Broadcasting--Radio 0.7 Paper & Forest Products 0.5 Business Equipment 0.4 Transportation--Rail Manufacturing 0.4 Transportation--Cargo 0.4 Farming & Agriculture 0.4 Non-Durable Consumer Products 0.4 Grocery 0.3 Textiles & Leather 0.3 Broadcasting--Diversified 0.2 Broadcasting--Television 0.1 Telecommunications--Long Distance 0.1 Transportation--Personal 0.0 ----- Total Long Term Investments 98.7% Short-Term Investments 1.3 ----- Total Investments 100.0% 6 Subject to change daily.

(j) The borrower is in the process of restructuring or amending the terms of this loan. * Senior Loans in the Trust's portfolio generally are subject to mandatory and/or optional prepayment. 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 30 See Notes to Financial Statements VAN KAMPEN SENIOR INCOME TRUST PORTFOLIO OF INVESTMENTS -- JANUARY 31, 2006 (UNAUDITED) continued 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.

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 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 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 are valued, where possible, using independent market indicators provided by independent pricing sources approved by the Board of Trustees. Other Senior Loans 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. 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 the underlying debt security. The Trust will make payment for such securities only upon 38 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2006 (UNAUDITED) continued 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. 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, 2005, the Trust had an accumulated capital loss carryforward for tax purposes of $211,408,105, 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 to be 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. 39 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2006 (UNAUDITED) continued The tax character of distributions paid for the year ended July 31, 2005 was as follows: Distributions paid from: Ordinary income........................................... $102,806,311 Long-term capital gain.................................... -0- ------------ $102,806,311 ============ As of July 31, 2005, the components of distributable earnings on a tax basis were as follows: Undistributed ordinary income............................... $5,272,503 Long-term capital gain...................................... -0- Net realized gains and losses may differ for financial and tax reporting purposes primarily as a result of the deferral of losses resulting from wash sale transactions and other losses that were recognized for book purposes but not tax purposes at the end of the fiscal year. 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.

As such, the Trust assumes the credit risk of the borrower, selling participant or other persons interpositioned between the Trust and the borrower. 41 VAN KAMPEN SENIOR INCOME TRUST NOTES TO FINANCIAL STATEMENTS -- JANUARY 31, 2006 (UNAUDITED) continued At January 31, 2006, the following sets forth the selling participants with respect to interests in Senior Loans purchased by the Trust on a participation basis.

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 that 50%) of the Fund's total assets based on the relative amounts borrowed or preferred shares issued.
