INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 4.75 percent for Class A shares, a contingent deferred sales charge of 4.00 percent for Class B shares (in year one and declining to zero after year five), a contingent deferred sales charge of 1.00 percent for Class C shares in year one, and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares six years after purchase. The since inception returns for Class C shares reflect the conversion of Class C shares into Class A shares ten years after purchase. Class I shares are available for purchase exclusively by investors through (i) tax-exempt retirement plans with assets of at least $1 million (including 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase plans, defined benefit plans and non-qualified deferred compensation plans), (ii) fee-based investment programs with assets of at least $1 million and (iii) institutional clients with assets of at least $1 million. Class I shares are offered without any sales charges on purchases or sales and do not include combined 12b-1 fees and service fees. Figures shown above assume reinvestment of all dividends and capital gains. SEC yield is a calculation for determining the amount of portfolio income, excluding non-income items as prescribed by the SEC. Yields are subject to change. Lehman Brothers Credit Bond Index is a market-weighted index of investment-grade corporate fixed-rate debt issues with maturities of one year or more. Lipper Corporate BBB-Rated Index is an index of funds with similar investment objectives as this fund. Indexes are unmanaged and do not include any sales charges or fees. Such costs would lower performance. It is not possible to invest directly in an index. Source: Lipper Inc. 1 Fund Report FOR THE SIX-MONTH PERIOD ENDED FEBRUARY 28, 2006 MARKET CONDITIONS Despite high energy prices and the devastation of the Gulf Coast hurricanes, the U.S. economy demonstrated resilience during the reporting period. While some observers initially expected that Hurricane Katrina would deliver a significant blow to the U.S. economy, it became apparent as the weeks progressed that the impact on the economy would be much smaller and more temporary than many had anticipated. Moreover, sharply higher energy prices failed to interrupt the positive economic momentum. The first two months of 2006 proved somewhat uneventful. As many expected, the Federal Open Market Committee (the Fed) once again raised the federal funds target rate by a quarter-point to 4.50 percent in January. Also as expected, Alan Greenspan retired in January after more than 18 years as chairman of the Federal Reserve Board of Governors. Ben S. Bernanke replaced him, and in his first Congressional testimony as chairman, Bernanke acknowledged some risks to the Fed's relatively contained inflation forecast and recognized the potential for upward pressure on inflation if certain conditions persisted unchecked. The chairman also indicated that he concurred with the Fed's January policy statement which noted the potential for further tightening of monetary policy. U.S. Treasury yields rose for the period overall. Short- and intermediate-term Treasury yields were more responsive to stronger-than-expected economic data and rose more rapidly than longer-term Treasury yields. Accordingly, the yield curve (which measures the difference between short- and long-term bond yields) flattened during the six-month period. U.S. investment-grade corporate bonds underperformed other major bond market sectors. Sector returns were unevenly distributed, with a few key names driving performance within each sector. Overall, Aa-rated issues posted the highest returns while medium quality, Baa-rated issues lagged. Among the investment-grade corporate sub-sectors, the best performers were energy, utilities and banking issues. Within the high yield sector, lower-rated issues posted the best performance with forest products, telecom and consumer products leading the way. 2 PERFORMANCE ANALYSIS The fund returned -0.53 percent for the six months ended February 28, 2006 (Class A shares, unadjusted for sales charges). In comparison, the fund's benchmarks, the Lehman Brothers Credit Bond Index and the Lipper Corporate BBB-Rated Index, returned -0.78 percent and 0.34 percent for the period, respectively. TOTAL RETURN FOR THE SIX-MONTH PERIOD ENDED FEBRUARY 28, 2006 <Table> <Caption> - -------------------------------------------------------------------------------------- LEHMAN BROTHERS LIPPER CORPORATE CREDIT BOND BBB-RATED CLASS A CLASS B CLASS C CLASS I INDEX INDEX -0.53% -0.92% -0.91% -0.40% -0.78% 0.34% - -------------------------------------------------------------------------------------- </Table> The performance for the four share classes varies because each has different expenses. The fund's total return figures assume the reinvestment of all distributions, but do not reflect the deduction of any applicable sales charges. Such costs would lower performance. Past performance is no guarantee of future results. See Performance Summary for standardized performance information and index definitions. During the period, we kept the fund's overall interest-rate exposure well below that of the Lehman benchmark. This posture was beneficial as interest rates rose across the yield curve, especially in the short-term and intermediate-term portions of the curve. Favorable sector and security selection decisions, most notably an underweight in the automotive sector, benefited relative performance versus the Lehman benchmark. Within the investment-grade portion of the fund, a focus on higher-rated issues contributed positively to both absolute and relative performance. While the fund emphasizes investment-grade credits, it also includes a smaller allocation to higher yielding securities. Within the high yield portion, a conservative approach detracted from performance as higher-rated issues underperformed the riskiest segment of the high yield market (issues rated CCC and below). 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 fund in the future. 3 <Table> RATINGS ALLOCATIONS AS OF 02/28/06 AAA/Aaa 13.8% AA/Aa 15.0 A/A 28.4 BBB/Baa 35.7 BB/Ba 3.7 B/B 3.4 SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 02/28/06 U.S. Government Agency Obligations 10.0% Banking 9.6 Electric 8.7 Wireline Communications 7.3 Noncaptive-Consumer Finance 5.3 Life Insurance 4.6 Healthcare 4.5 Noncaptive-Diversified Finance 4.0 Diversified Manufacturing 3.9 Property & Casualty Insurance 3.4 Food/Beverage 3.3 Automotive 2.4 Paper 2.2 Railroads 2.1 Media-Noncable 1.6 Media-Cable 1.5 Retail 1.5 Natural Gas Pipelines 1.2 Consumer Products 1.2 Aerospace & Defense 0.9 Environmental & Facilities Services 0.9 Brokerage 0.9 Supermarkets 0.9 Textile 0.9 Wireless Communications 0.8 Chemicals 0.8 Gaming 0.8 Integrated Energy 0.8 Technology 0.7 Construction Machinery 0.7 Natural Gas Distributors 0.7 Entertainment 0.6 Lodging 0.5 Building Materials 0.5 Real Estate Investment Trusts 0.4 Independent Energy 0.4 Transportation Services 0.3 Pharmaceuticals 0.3 Oil Field Services 0.1 Refining 0.0 ----- </Table> <Table> (continued on next page) </Table> 4 <Table> <Caption> SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 02/28/06 (continued from previous page) Total Long-Term Investments 91.2% Short-Term Investments 6.5 Other Assets in Excess of Liabilities 2.3 ----- Total Net Assets 100.0% </Table> Subject to change daily.

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD You may obtain a copy of the fund's Proxy Voting Policy and Procedures without charge, upon request, by calling toll free (800) 847-2424 or by visiting our Web site at www.vankampen.com. It is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. You may obtain information regarding how the fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 without charge by visiting our Web site at www.vankampen.com. This information is also available on the Securities and Exchange Commission's Web site at http://www.sec.gov. 7 Expense Example As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 9/1/05 - 2/28/06. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD* ------------------------------------------------ 9/1/05 2/28/06 9/1/05-2/28/06 Class A Actual...................................... $1,000.00 $ 994.72 $4.65 Hypothetical................................ 1,000.00 1,020.09 4.71 (5% annual return before expenses) Class B Actual...................................... 1,000.00 990.81 8.39 Hypothetical................................ 1,000.00 1,016.39 8.50 (5% annual return before expenses) Class C Actual...................................... 1,000.00 990.85 8.39 Hypothetical................................ 1,000.00 1,016.39 8.50 (5% annual return before expenses) Class I Actual...................................... 1,000.00 995.97 3.46 Hypothetical................................ 1,000.00 1,021.29 3.51 (5% annual return before expenses) </Table> * Expenses are equal to the Fund's annualized expense ratio of 0.94%, 1.70%, 1.70% and 0.70% for Class A, B, C and I Shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Corporate Bond Fund (the "Fund") is organized as a Delaware statutory trust, and is registered as a diversified open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's primary investment objective is to seek to provide current income with preservation of capital. The Fund commenced investment operations on September 23, 1971. The Fund offers Class A Shares, Class B Shares, Class C Shares and Class I Shares. Each class of shares differs by its initial sales load, contingent deferred sales charges, the allocation of class specific expenses and voting rights on matters affecting a single class. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Fixed income investments are stated at value using market quotations or indications of value obtained from an independent pricing service. Investments in securities listed on a securities exchange are valued at their last sale price as of the close of such securities exchange. Listed and unlisted securities for which the last sales price is not available are valued at the mean of the bid and asked prices. For those securities where quotations or prices are not available as noted above, valuations are determined in accordance with procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange in 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 Fund may invest in repurchase agreements, which are short-term investments in which the Fund acquires ownership of a debt security and the seller agrees to repurchase the security at a future time and specified price. The Fund may invest independently in repurchase agreements, or transfer uninvested cash balances into a pooled cash account along with other investment companies advised by Van Kampen Asset Management (the "Adviser") or its affiliates, the daily aggregate of which is invested in repurchase agreements. Repurchase agreements are fully collateralized by the underlying debt security. The Fund 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 Fund. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Discounts on debt securities purchased are accreted and premiums are amortized over the expected life of each applicable security. Other income is comprised primarily of consent fees. Consent fees are earned as compensation for agreeing to changes in the terms of debt instruments. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for 25 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2006 (UNAUDITED) continued distribution and service fees and incremental transfer agency costs which are unique to each class of shares. D. FEDERAL INCOME TAXES It is the Fund'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 Fund 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 these losses against any future realized capital gains. During the prior fiscal year, the Fund utilized capital losses carried forward of $12,985,784. At August 31, 2005, the Fund had an accumulated capital loss carryforward for tax purposes of $5,997,297 which will expire according to the following schedule: <Table> <Caption> AMOUNT EXPIRATION - ------ ---------- $5,560,726.................................................. August 31, 2011 436,571...................................................

(20,332,741) ------------ Net tax unrealized depreciation on investments.............. $ (5,772,670) ============ </Table> E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly dividends from net investment income. Net realized gains, if any, are distributed annually. Distributions from net realized gains for book purposes may include short-term capital gains and gains on future transactions. All short-term capital gains and a portion of future gains are included in ordinary income for tax purposes. The tax character of distributions paid during the year ended August 31, 2005 was as follows: <Table> Distributions paid from: Ordinary Income........................................... $27,486,058 Return of Capital......................................... -- ----------- $27,486,058 =========== </Table> As of August 31, 2005 there were no distributable earnings on a tax basis. Net realized gains or losses may differ for financial and tax reporting purposes as a result of the deferral of losses relating to wash sales transactions. F. EXPENSE REDUCTIONS During the six months ended February 28, 2006, the Fund's custody fee was reduced by $21,415 as a result of credits earned on cash balances. 26 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2006 (UNAUDITED) continued 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Fund's Investment Advisory Agreement, the Adviser will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows: <Table> <Caption> AVERAGE DAILY NET ASSETS % PER ANNUM First $500 million.......................................... .42% Next $750 million........................................... .35% Over $1.250 billion......................................... .22% </Table> For the six months ended February 28, 2006, the Fund recognized expenses of approximately $17,900 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a Trustee of the Fund is a partner of such firm and he and his law firm provide legal services as legal counsel to the Fund. Under separate Accounting Services and Chief Compliance Officer ("CCO") Employment agreements, the Adviser provides accounting services and the CCO provides compliance services to the Fund. The costs of these services are allocated to each fund. For the six months ended February 28, 2006, the Fund recognized expenses of approximately $21,200, representing Van Kampen Investment Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting services to the Fund, 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 Accounting Services and CCO Employment agreement are reported as part of "Other" expenses on the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended February 28, 2006, the Fund recognized expenses of approximately $653,500 representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are officers of Van Kampen. The Fund 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. Amounts deferred are retained by the Fund and, to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of approximately $85,200 are included in "Other" assets on the Statement of Assets and Liabilities at February 28, 2006. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. 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 Fund. The maximum annual benefit per trustee under the plan is $2,500.

REDEMPTION FEE Effective September 26, 2005, the Fund assesses a 2% redemption fee on the proceeds of Fund shares that are redeemed (either by sale or exchange) within the seven days of purchase. The redemption fee is paid directly to the Fund. For the period ended February 28, 2006, the Fund received redemption fees of approximately $1,000, which are reported as part of "Cost of Shares Repurchased" on the Statement of Changes in Net Assets. 5. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $196,125,256 and $143,701,945, respectively. 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 Fund has a variety of reasons to use derivative instruments, such as to attempt to protect the Fund against possible changes in the market value of its portfolio or to generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in unrealized appreciation/depreciation. Upon 28 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2006 (UNAUDITED) continued 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. Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. A. FUTURES CONTRACTS During the period, the Fund invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in futures on U.S. Treasury Notes. Upon entering into futures contracts, the Fund 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 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 February 28, 2006, were as follows: <Table> <Caption> CONTRACTS Outstanding at August 31, 2005.............................. 2,335 Futures Opened.............................................. 6,749 Futures Closed.............................................. (6,867) ------ Outstanding at February 28, 2006............................ 2,217 ====== </Table> B. CREDIT DEFAULT SWAPS The Fund may enter into credit default swap contracts for hedging purposes or to gain exposure to a credit in which the Fund 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 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 Fund 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. Credit default swaps may involve greater risks than if a Fund 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 Fund will have contractual remedies pursuant to the agreements related to the transaction. 29 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2006 (UNAUDITED) continued 7. DISTRIBUTION AND SERVICE PLANS Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"), an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively, the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate the Distributor for the distribution, shareholder servicing and maintenance of shareholder accounts for these shares. Under the Plans, the Fund will incur annual fees of up to .25% of Class A average daily net assets and up to 1.00% each of Class B and Class C average daily net assets. These fees are accrued daily and paid to the Distributor monthly. The amount of distribution expenses incurred by the Distributor and not yet reimbursed ("unreimbursed receivable") was approximately $1,464,900 and $2,600 for Class B and Class C Shares, respectively. These amounts may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, the distribution fee is reduced. 8. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were consolidated. The consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. Plantiffs have filed a Motion for Leave to file a Supplemental Pleading that would, among other things, expand the allegations and alleged class. The defendants have moved to dismiss this action and otherwise intend to defend it vigorously. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with the consolidated complaint described in the preceding paragraph. Defendants moved to dismiss the complaint and intend otherwise to vigorously defend it. Plaintiff sought leave to 30 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2006 (UNAUDITED) continued file a second amended derivative complaint that alleges that the Adviser permitted or recklessly disregarded market timing and late trading in its proprietary mutual funds in order to increase assets under management and fees. However, pursuant to an agreement between the parties, the plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants moved to dismiss this matter, which motion was granted in part and denied in part. Defendants moved for reconsideration of those claims that were denied. Plaintiff subsequently dismissed the trustee defendants from the action, in exchange for the execution of a tolling agreement by the trustees permitting plaintiff to bring the same claims against the trustees at a later date should plaintiff deem necessary. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 9. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 31 VAN KAMPEN CORPORATE BOND FUND BOARD OF TRUSTEES, OFFICERS AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.
