Welcome, Shareholder

In this report, you’ll learn about how your investment in Van Kampen Senior Income Trust performed during the semiannual period. The portfolio management team will provide an overview of the market conditions and discuss some of the factors that affected investment performance during the reporting period. In addition, this report includes the trust’s financial statements and a list of trust investments as of January 31, 2009.

Market forecasts provided in this report may not necessarily come to pass. There is no assurance that the trust will achieve its investment objective. Trusts are subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of the trust shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in this trust.

An investment in senior loans is subject to certain risks such as loan defaults and illiquidity due to insufficient collateral backing.

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. For the most recent month-end performance figures, please visit vankampen.com or speak with your financial advisor. 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.

Trust Report

For the six-month period ended January 31, 2009

Market Conditions

The six-month period under review was an unprecedented period in the history of the financial markets. Following the government takeover of Fannie Mae and Freddie Mac in early September and the bankruptcy of Lehman Brothers shortly thereafter, the credit crisis reached new heights as investor confidence plummeted and the credit markets seized. A massive flight to quality ensued as investors shunned risky assets in favor of the relative safety of U.S. Treasury securities. As a result, all other sectors of the market experienced significant price deterioration, a trend that largely continued throughout the end of the year. Concerns about the economy exacerbated the market sell-off as various economic indicators continued to weaken, further undermining investor confidence. In December 2008, it was confirmed that the economy was in recession, and had in fact been since the prior December.

The government took substantial steps by implementing various fiscal and monetary policies designed to be supportive, yet by the end of January 2009, their efforts had done little to calm the markets or boost the economy. With unemployment still on the rise and consumer spending and home prices declining further, the outlook for the rest of the year appeared negative. It is possible, however, that further government intervention to stabilize the financial industry and stem home foreclosures could ultimately help stimulate the economy.

The senior loan market suffered in the risk-averse environment as loan demand declined and funds began selling loans in preparation for year-end redemptions. Funds also sold loans as part of the process of reducing leverage in order to remain in compliance with leverage regulations. As a result, the fourth quarter of 2008 was the worst quarter on record for the senior loan asset class, with loan values declining by 25.1 percent (as measured by the S&P/LSTA Leveraged Loan Index), far surpassing the third-quarter decline of 8.6 percent. For calendar year 2008, senior loans were down 34.6 percent.

As of year-end, the technical demand/supply picture had begun to improve. Funds appeared to be through with most of their forced selling and buyers began to emerge, which helped to stabilize loan prices. In January 2009, the loan market rallied strongly, posting a record one-month gain of 5.2 percent. Nonetheless, the market remained volatile at month-end and credit fundamentals were still deteriorating. Additionally, default rates reached 5 percent and most market observers expect this trend to continue. Given the senior secured nature of loans, however, we still find current yields compelling.

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, 2009, the Trust returned –45.26 percent on a market price basis and –52.88 percent on an NAV basis.

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 adhere to our research-intensive investment process, employing a bottom-up security selection process driven by thorough analysis of individual company fundamentals, and have not relaxed our rigorous credit standards. We believe this approach will enable us to help limit our credit losses during this down cycle and allow us to take advantage of opportunities that arise during volatile periods such that we are currently experiencing.

We continued to position the portfolio defensively during the reporting period, generally avoiding sectors or industries that we believe are vulnerable to cyclical economic downturns. For example, the Trust remained underweighted in the auto, airline and retail industries because of their susceptibility to the weakening economy.

The Trust remained fully invested in senior secured loans, and used a modest amount of leverage which may allow us to enhance the Trust’s yield while keeping credit standards high. Leverage involves borrowing at a floating short-term rate and reinvesting the proceeds at a higher rate. 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, assuming no defaults, 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.) While we believe this portfolio structure (fully invested, modest leverage) adds value for shareholders over a full cycle, it has been a drag on performance over the past 18 months. Because, in our view, the recent market volatility has been driven as much by technical factors as by changes in underlying fundamentals, we have

3

not materially altered the use of leverage in the Trust as we believe it is difficult to “time” technical events in the market. Therefore, portfolio composition continues to be driven by fundamental credit research. As of the end of the period, the Trust’s largest sector weightings were healthcare, gaming, publishing, and food and beverage products.

Going forward, we will remain focused on ensuring the Trust has sufficient liquidity while maintaining a high quality, well-diversified portfolio of issuers with stable cash flows, strong management teams, and collateral value sufficient to provide a solid second way out in a worst-case default scenario.

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.

The aggregate value of restricted securities represents less than 0.1% of the net assets applicable to common shares of the Trust.

*

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 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 or (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.

Ratings Allocation as of 1/31/09

BBB/Baa	0.4	%
BB/Ba	34.1
B/B	31.7
CCC/Caa	7.5
CC/Ca	0.3
C/C	0.6
Non-Rated	25.4

Ratings allocations are as a percentage of long-term debt obligations. Ratings allocations based upon ratings as issued by Standard and Poor’s and Moody’s, respectively. Bank Loans rated below BBB by Standard and Poor’s or Baa by Moody’s are considered to be below investment grade.

Notes to Financial Statements  n  January 31, 2009 (Unaudited)

1. Significant Accounting Policies

Van Kampen Senior Income Trust (the “Trust”) is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). 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 23, 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 obtained 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 adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, Fair Value Measurements (FAS 157), effective August 1, 2008. In accordance with FAS 157, fair value is defined as the price that the Trust would receive to

35

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. FAS 157 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Trust’s investments. The inputs are summarized in the three broad levels listed below.

Level 1—	quoted prices in active markets for identical investments
Level 2—	other significant observable inputs (including quoted prices for similar           investments, interest rates, prepayment speeds, credit risk, etc.)
Level 3—	significant unobservable inputs (including the Trust’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of January 31, 2009 in valuing the Trust’s investments carried at value:

	Investments
	in Loans and		Other Financial
Valuation Inputs	Securities		Instruments*			Liabilities
Level 1—Quoted Prices	$	145,995	$	-0-		$	-0-
Level 2—Other Significant Observable Inputs		935,091,502		(1,775,588	)		(21,440,361	)
Level 3—Significant Unobservable Inputs		14,951,432		-0-			(33,881	)
Total	$	950,188,929	$	(1,775,588	)	$	(21,474,242	)

* Other financial instruments include swap contracts.

Following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining value:

	Investments
	in Loans and
	Securities			Liabilities
Balance as of 7/31/2008	$	12,511,241		$	-0-
Accrued discounts/premiums		38,508			-0-
Realized gain/loss		7,628			-0-
Change in unrealized appreciation/depreciation		(11,171,296	)		(33,881	)
Net purchases/sales		434,068			-0-
Net transfers in and/or out of Level 3		13,131,283			-0-
Balance as of 1/31/09	$	14,951,432		$	(33,881	)
Net change in unrealized appreciation/depreciation from investments still held as of 1/31/09	$	(11,171,296	)	$	(33,881	)

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 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, 2009, the Trust had no when-issued or delayed delivery purchase commitments.

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 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.

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. Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48) sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. Management has concluded there are no significant uncertain tax positions that would require recognition in the financial statements. If applicable, the Trust recognizes interest accrued related to unrecognized tax benefits in “Interest Expense” and penalties in “Other” expenses on the Statement of Operations. The Trust files tax returns with the U.S. Internal Revenue Service and various states. Generally, each of the tax years in the four year period ended July 31, 2008, remains subject to examination by taxing authorities.

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, 2008, the Trust had an

37

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

accumulated capital loss carryforward for tax purposes of $247,685,516 which will expire according to the following schedule.

Amount		Expiration
$	4,851,995		July 31, 2009
	122,716,095		July 31, 2010
	52,014,750		July 31, 2011
	29,634,358		July 31, 2012
	2,190,907		July 31, 2013
	6,730,384		July 31, 2014
	11,934,630		July 31, 2015
	17,612,397		July 31, 2016

At January 31, 2009, the cost and related gross unrealized appreciation and depreciation are as follows:

Cost of investments for tax purposes	$	1,694,430,981
Gross tax unrealized appreciation	$	4,626,277
Gross tax unrealized depreciation		(748,868,329	)
Net tax unrealized depreciation on investments	$	(744,242,052	)

E. 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, 2008 were as follows:

Distributions paid from:
Ordinary income	$	147,096,403
Long-term capital gain		-0-
	$	147,096,403

As of July 31, 2008, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income $ -0-

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 and gains and losses recognized on securities for tax purposes but not for book purposes.

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

38

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

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, 2009, the Trust recognized expenses of approximately $103,500 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, 2009, the Trust recognized expenses of approximately $49,300 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.

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.

As of January 31, 2009, the Trust did not own shares of affiliated companies. Affiliated companies are defined by the 1940 Act, as those companies in which a fund holds 5% or more of the outstanding voting securities.

3. Capital Transactions

The Board of Trustees have approved a share repurchase program whereby the Trust may, when appropriate, repurchase its shares in the open market or in privately negotiated transactions at a price not above market value or net asset value (NAV), whichever is lower at the time of purchase.

4. Investment Transactions

During the period, the cost of purchases and proceeds from investments sold and repaid, excluding short-term investments, were $76,597,898 and $573,002,870, respectively.

5. Commitments

Pursuant to the terms of certain Senior Loan agreements, the Trust had unfunded loan commitments of approximately $60,006,000 as of January 31, 2009. The Trust intends to

39

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

reserve against such contingent obligations by designating cash, liquid securities and liquid Senior Loans as a reserve. The unrealized depreciation on these commitments of $21,474,242 as of January 31, 2009 is reported as “Unfunded Commitments” on the Statement of Assets and Liabilities.

6. 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. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contracts.

The Trust adopted the provisions of the FASB Staff Position Paper No. FAS 133-1 and FIN 45-4, Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No. 45 (FSP FAS 133-1 and FIN 45-4), effective January 31, 2009. FSP FAS 133-1 and FIN 45-4 requires the seller of credit derivatives to provide additional disclosure about its credit derivatives.

The Trust may enter into credit default swap contracts, a type of credit derivative, for hedging purposes or to gain exposure to a credit or index of credits 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 or index of issuers. A buyer of a credit 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. The seller in a credit default swap contract would be required to pay an agreed-upon amount to the buyer in the event of an adverse credit event of the issuer. This agreed-upon amount approximates the notional amount of the swap as disclosed in the table following the Portfolio of Investments and is estimated to be the maximum potential future payment that the seller could be required to make under the credit default swap contract. In the event of an adverse credit event, the seller generally does not have any contractual remedies against the issuer or any other third party. However, if a physical settlement is elected, the seller would receive the defaulted credit and, as a result, become a creditor of the issuer.

The current credit rating of each individual issuer is listed in the table following the Portfolio of Investments and serves as an indicator of the current status of the payment/performance risk of the credit derivative. Alternatively, for credit default swaps on an index of credits, the quoted market prices and current values serve as an indicator of the current status of the payment/performance risk of the credit derivative. Generally, lower credit ratings and increasing market values, in absolute terms, represent a deterioration of the credit and a greater likelihood of an adverse credit event of the issuer.

Credit default swaps may involve greater risks than if a Trust had invested in the issuer directly. Credit default swaps are subject to general market risk, counterparty risk and credit risk. Swap agreements are not entered into or traded on exchanges and there is no central

40

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

clearing or guaranty function for swaps. Therefore, swaps are subject to the risk of default or non-performance by the counterparty. If there is a default by the counterparty to a swap agreement, the Trust will have contractual remedies pursuant to the agreements related to the transaction. Counterparties are required to pledge collateral daily (based on the valuation of each swap) on behalf of the Trust with a value approximately equal to the amount of any unrealized gain. Reciprocally, when the Trust has an unrealized loss on a swap contract, the Trust has instructed the custodian to pledge cash or liquid securities as collateral with a value approximately equal to the amount of the unrealized loss. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate. Cash collateral is disclosed in the table following the Portfolio of Investments. For cash collateral received, the Trust pays a monthly fee to the counterparty based on the effective rate for Federal Funds.

7. 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, 2009, 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
	(000)		(000)
Selling participant
Goldman Sachs Lending Partners	$	1,250	$	403

8. Borrowings

The Trust may utilize financial leverage to the maximum extent allowable under the 1940 Act. Under the 1940 Act, a Trust generally may not (i) borrow money greater than 331/3% 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 331/3% 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 annual revolving credit and security agreement. This revolving credit agreement is secured by the assets of the Trust. In connection with this agreement, for the six months ended January 31, 2009, the Trust incurred fees of approximately $3,257,200. For the six months ended January 31, 2009, the average daily balance of borrowings under the Amended and Restated Revolving Credit and Security Agreement was $344,402,174 with a weighted average interest rate of 3.09%. Effective September 13, 2008, the Trust changed its Credit and Security Agreement to $625 million.

9. Preferred Shares Issuance

The Trust has outstanding 2,800 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

41

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

total issuance of $350 million. Dividends are cumulative and the dividend rates are generally reset every seven days through an auction process. Beginning on February 12, 2008 and continuing through January 31, 2009, all series of preferred shares of the Trust were not successfully remarketed. As a result, the dividend rates of these preferred shares were reset to the maximum applicable rate on APS. The average rate in effect on January 31, 2009 was 1.810%. During the six months ended January 31, 2009, the rates ranged from 1.733% to 7.144%.

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.

10. 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.

11. Accounting Pronouncement

On March 19, 2008, Financial Accounting Standards Board released Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (FAS 161). FAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of FAS 161 is required for fiscal years and interim periods beginning after November 15, 2008. At this time, management does not believe the adoption of FAS 161 will impact the financial statement amounts; however, additional footnote disclosures may be required about the use of derivative instruments and hedging items.

12. Legal Matters

The Trust is one of numerous defendants (“Lenders”) that have been named in an adversary proceeding pending in the Bankruptcy Court of the Southern District of Florida (the “Court”). The action, entitled In re Tousa Inc., et al., was filed on July 15, 2008, by the Official Committee of Unsecured Creditors of home building companies to which the Lenders loaned money through different lending facilities. An amended complaint was filed on October 17, 2008. Plaintiff alleges that monies used to repay the Lenders should be avoided as fraudulent and preferential transfers under the bankruptcy laws. More specifically, Plaintiff alleges that subsidiaries of the home building companies were allegedly forced to become co-borrowers and guarantors of the monies used to repay the Lenders, and that the subsidiaries did not receive fair consideration or reasonably equivalent value when they transferred the proceeds to repay the Lenders. Plaintiff seeks to avoid the transfers and other equitable relief. The Trust and the other Lenders are named as defendants in two separate lending capacities; first, as lenders in a credit agreement (the “Credit Lenders”); and second, as lenders in a term loan (the “Term Loan Lenders”). The Trust, as Credit Lender, moved to dismiss the amended

42

Van Kampen Senior Income Trust
Notes to Financial Statements  n  January 31, 2009 (Unaudited)  continued

complaint. The Court denied the motion to dismiss on December 4, 2008. The Trust and the other Credit Lenders filed a motion for leave to appeal the dismissal, which was denied on February 23, 2009. Plaintiff thereafter filed a Second Amended Complaint that was superseded by a Third Amended Complaint. The Trust filed two answers to the Third Amended Complaint in its respective capacities as a Credit Lender and a Term Loan Lender. The Court has ordered that all parties take part in a mediation to be held in March 2009.

The Trust is also one of the defendants that have been named in an adversary proceeding pending in the United States District Court for the Southern District of New York. The action, entitled Robertson v. Arch et al., was filed on January 26, 2009, by certain individual holders of auction rate preferred securities (“ARPS”) issued by certain Van Kampen funds, including the Trust. The suit names the relevant funds and the funds’ trustees as defendants. The complaint alleges breach of fiduciary duty for failure to redeem the ARPS. It seeks, among other things, an order compelling the redemption of plaintiffs’ ARPS and consequential damages.
