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 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 eight 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 Rule 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.

The Lehman Brothers Corporate 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.

Fund Report

FOR THE 12-MONTH PERIOD ENDED AUGUST 31, 2006

MARKET CONDITIONS

Several events shaped trends in the fixed-income markets during the 12-month
review period. The series of natural disasters that struck the U.S. in mid-2005,
combined with sharply rising energy prices, generated concern regarding their
effect on economic growth. As the months progressed, however, it became apparent
that the impact on the economy would be less than anticipated. In fact, the
economy demonstrated considerable resilience and real gross domestic product
(GDP) growth averaged near 4 percent throughout 2005.

The first months of 2006 provided few surprises in the bond market. To virtually
no one's surprise, the Federal Open Market Committee (the "Fed") continued to
raise the target federal funds rate by 25 basis points at each of its meetings
during the first half of the year, bringing the rate to 5.25 percent at the end
of June.

Also as expected, comments made by Fed members after their May and June meetings
indicated that they will rely heavily on economic data in making future
decisions concerning the direction of interest rates. Based on these comments,
it appears that the Fed will be driven by the weight of the economic data more
so now than perhaps at anytime over the past few years.

During the last months of the period, in response to the expectation of a pause
in the Fed's tightening campaign, the U.S. bond market enjoyed the best
three-month run of positive returns since the Fed began its tightening cycle in
2004. In fact, despite negative returns in the first half of 2006, all
fixed-income asset classes ended August with positive year-to-date returns. As
anticipated, the Fed did finally pause at its August meeting, following a run of
17 consecutive increases in the target federal funds rate.

Due mainly to concerns over inflation and increased risk in the corporate
market, the credit sector had trouble keeping pace with other fixed-income
sectors. Within the investment-grade portion of the market, higher-rated issues
outperformed lower-rated issues. Improving economic conditions boosted the
financials sector, leading it to outpace both utilities and industrials.

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 duration (a measure of interest
rate sensitivity) well below that of the benchmark. This posture was beneficial
to performance as interest rates rose across the market, especially in the
short- and intermediate-portions of the yield curve.

Within the credit portion of the portfolio, we continued to employ a defensive
strategy with a focus on higher-quality securities, which benefited the fund's
relative performance. Additionally, strong security selection--particularly in
the paper and forest products, financial and automotive sectors--contributed
positively to performance.

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.

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 charges on redemptions of Class B and C Shares;
and redemption fees; 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 costs (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 3/1/06 - 8/31/06.

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 or redemption fees.
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.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

On May 22, 2006, the Board of Trustees, and the independent trustees voting
separately, determined that the terms of the investment advisory agreement are
fair and reasonable and approved the continuance of the investment advisory
contract as being in the best interests of the Fund and its shareholders. In
making its determination, the Board of Trustees considered materials that were
specifically prepared by the investment adviser at the request of the Board and
Fund counsel, and by an independent provider of investment company data
contracted to assist the Board, relating to the contract review process. The
Board also considered information received periodically about the portfolio,
performance, the investment strategy, portfolio management team and fees and
expenses of the Fund. The Board of Trustees considered the contract over a
period of several months and the non-management trustees held sessions both with
the investment adviser and separate from the investment adviser in reviewing and
considering the contract.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
existing and alternative breakpoints in the Fund's investment advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies and/or other products at different asset levels,
and considered the trends in the industry versus historical and projected assets
of the Fund. The Board of Trustees evaluated other benefits the investment
adviser and its affiliates derive from their relationship with the Fund. The
Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and
regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors

                                                                               9


together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund. The Fund
discloses information about its portfolio management team members and their
experience in its prospectus. The trustees also discuss certain other services
which are provided on a cost-reimbursement basis by the investment adviser or
its affiliates to the Van Kampen funds including certain accounting,
administrative and legal services. The Board has determined that the nature,
extent and quality of the services provided by the investment adviser support
its decision to approve the investment advisory contract.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report and in
the Fund's prospectus. The trustees discuss with the investment adviser the
level of advisory fees for this Fund relative to comparable funds and other
products advised by the adviser and others in the marketplace. The trustees
review not only the advisory fees but other fees and expenses (whether paid to
the adviser, its affiliates or others) and the Fund's overall expense ratio. The
Fund discloses more information about its fees and expenses in its prospectus.
The Board has determined that the performance, fees and expenses of the Fund
support its decision to approve the investment advisory contract.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees discuss with the investment adviser its revenues and expenses,
including among

 10


other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory contract.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
and growth prospects of the Fund and how that relates to the Fund's expense
ratio and particularly the Fund's advisory fee rate. In conjunction with its
review of the investment adviser's profitability, the trustees discuss with the
investment adviser how more (or less) assets can affect the efficiency or
effectiveness of managing the Fund's portfolio and whether the advisory fee
level is appropriate relative to current and projected asset levels and/or
whether the advisory fee structure reflects economies of scale as asset levels
change. The Board has determined that its review of the actual and potential
economies of scale of the Fund support its decision to approve the investment
advisory contract.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory contract.

                                                                              11

VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2006

1. 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. Credit default swaps are valued using market
quotations from brokers. 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. The Fund 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 Fund will segregate assets with the
custodian having an aggregate value at least equal to the amount of the
when-issued or delayed delivery purchase

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2006 continued

commitments until payment is made. At August 31, 2006, the Fund had $14,295,462
of when-issued or delayed delivery purchase commitments.

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 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. At August 31, 2006, the Fund had an accumulated capital loss carryforward
for tax purposes of $6,357,540, which will expire according to the following
schedule:

<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 futures transactions. All
short-term capital gains and a portion of futures gains are included in ordinary
income for tax purposes.

                                                                              29

    The tax character of distributions paid during the years ended August 31,
2006 and 2005 was follows:

</Table>

    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under U.S. generally accepted accounting principles and
federal income tax purposes, permanent differences between book and tax basis
reporting have been identified and appropriately reclassified on the Statement
of Assets and Liabilities. Permanent book and tax differences of $5,563 related
to the Fund's investments in other regulated investment companies and $198,750
related to consent fee income received from tender offers were reclassified from
accumulated undistributed net investment income to accumulated net realized
loss. A permanent book and tax difference of $23,682 related to the recognition
of net realized losses on paydowns of mortgage pool obligations and $1,847,024
related to book to tax amortization differences were reclassified from
accumulated undistributed net investment income to accumulated net realized
loss. Additionally, permanent book to tax differences of $179,968 and $1,925
relating to income from swap transactions were reclassified from accumulated net
realized loss to accumulated undistributed net investment income and capital,
respectively.

    As of August 31, 2006 the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $294,973
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes as a result of gains or losses recognized for tax purposes on open
futures transactions at August 31, 2006 and post October losses of $1,347,670
which are not recognized for tax purposes until the first day of the following
fiscal year.

F. EXPENSE REDUCTIONS During the year ended August 31, 2006, the Fund's custody
fee was reduced by $39,808 as a result of credits earned on cash balances.

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:

VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2006 continued

    For the year ended August 31, 2006, the Fund recognized expenses of
approximately $19,000 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 year ended August 31, 2006, the Fund recognized
expenses of approximately $51,400 representing Van Kampen Investments 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 year ended
August 31, 2006, the Fund recognized expenses of approximately $1,395,400
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 $89,500 are
included in "Other" assets on the Statement of Assets and Liabilities at August
31, 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.

    For the year ended August 31, 2006, Van Kampen, as Distributor for the Fund,
received commissions on sales of the Fund's Class A Shares of approximately
$691,900 and contingent deferred sales charge (CDSC) on redeemed shares of
approximately $251,300. Sales charges do not represent expenses of the Fund.

                                                                              31

4. 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
seven days of purchase. The redemption fee is paid directly to the Fund. For the
period ended August 31, 2006, the Fund received redemption fees of approximately
$2,800, which are reported as part of "Cost of Shares Repurchased" in the
Statement of Changes in Net Assets. The per share impact from redemption fees
paid to the Fund was less than $0.01.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $375,011,406 and $304,164,116,
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 may use derivative instruments for a variety of reasons, 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

 32


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2006 continued

appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying the futures contract. Risks may
arise as a result of the potential inability of the counterparties to meet the
terms of their contracts.

    Summarized below are the specific types of derivative financial instruments
used by the Fund.

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds or 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 year ended August 31, 2006, were
as follows:

</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. 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 in the Statement of Operations.

                                                                              33


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2006 continued

    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.

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 sale, 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 $1,154,400 and $0 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 and certain affiliates of the Adviser are named as defendants in a
derivative action 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 Van Kampen 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
derivative action was coordinated with a direct action alleging related
violations of defendants' statutory disclosure obligations and fiduciary duties
with respect to the payments described above. In addition, this derivative
action was stayed by agreement of the parties pending rulings on the motion to
dismiss the direct action and the motion to dismiss another derivative action
brought by the same plaintiff that brought this derivative action, alleging
market timing and late trading in the Van Kampen funds. In April 2006, the court
granted defendants' motion to dismiss the direct action. In June 2006, the court
granted defendants' motion to dismiss the market timing action. Accordingly, the
stay on this action was lifted. Plaintiff and defendants have agreed that this
action should be dismissed in light of the rulings dismissing the two cases
discussed above. The Court has approved a notice to shareholders regarding the
dismissal, which is located at the back of this Report.

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.

10. NEW ACCOUNTING PRONOUNCEMENT

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. The impact to the Fund's financial
statements, if any, is currently being assessed.

                                                                              35


VAN KAMPEN CORPORATE BOND FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of Van Kampen Corporate Bond Fund

We have audited the accompanying statement of assets and liabilities of Van
Kampen Corporate Bond Fund (the "Fund"), including the portfolio of investments,
as of August 31, 2006, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of August 31, 2006, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Van Kampen Corporate Bond Fund at August 31, 2006, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended in conformity with U.S. generally accepted
accounting principles.

                          Notice to Fund Shareholders

    As previously disclosed, a derivative action was filed on behalf of the Fund
against the Fund's investment adviser, broker-dealer, distributor, and Trustees.
The complaint alleges that defendants violated federal securities laws and state
laws in connection with certain economic incentive programs. The case is pending
before the Honorable Richard Owen, United States District Judge in the Southern
District of New York. Defendants have filed a motion to dismiss the complaint in
its entirety on numerous grounds, and that motion is still pending.

    On April 18, 2006, Judge Owen dismissed a separate lawsuit against Morgan
Stanley and all of the same corporate defendants that are named in the
derivative action. The Morgan Stanley suit related to the same incentive
programs that are at issue in the derivative action, and asserted many of the
same legal claims. In his decision, Judge Owen found that the programs do not
violate federal law, and that defendants had made the appropriate disclosures
concerning the programs. The plaintiffs in the Morgan Stanley suit did not
appeal from the decision, and that decision is now final.

    In light of this decision by Judge Owen -- as well as several other
decisions by other judges in the Southern District of New York and certain other
courts that have dismissed similar complaints against other investment funds --
plaintiff in the derivative action has determined that the suit would be
unsuccessful, if pursued further. Accordingly, plaintiff has asked Judge Owen to
dismiss the action. No attorneys' fees will be paid by defendants and no
consideration will be paid to the named plaintiff.

    All investors in the Fund are hereby provided notice of this proposed
dismissal. If you object to the proposed dismissal, your objection must be
mailed no later than November 29, 2006, in writing, to the Honorable Richard
Owen, United States District Judge, United States Courthouse, Room 640, 500
Pearl Street, New York, NY 10007-1312. Copies of the objection must also be
mailed to Denise Davis Schwartzman, Esquire, Chimicles & Tikellis LLP, 361 West
Lancaster Avenue, Haverford, PA 19041; and Richard A. Rosen, Esquire, Paul,
Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York,
NY 10019-6064.

financial expert. The designation or identification of a person as an audit
committee financial expert does not impose on such person any duties,

                          AUDIT AND NON-AUDIT SERVICES
                       PRE-APPROVAL POLICY AND PROCEDURES
                                     OF THE
                                VAN KAMPEN FUNDS

              AS ADOPTED JULY 23, 2003 AND AMENDED MAY 26, 2004(1)


1.       STATEMENT OF PRINCIPLES

         The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.(2)

         The SEC has issued rules specifying the types of services that an
independent auditor may not provide to its audit client, as well as the audit
committee's administration of the engagement of the independent auditor. The
SEC's rules establish two different approaches to pre-approving services, which
the SEC considers to be equally valid. Proposed services either: may be
pre-approved without consideration of specific case-by-case services by the
Audit Committee ("general pre-approval"); or require the specific pre-approval
of the Audit Committee ("specific pre-approval"). The Audit Committee believes
that the combination of these two approaches in this Policy will result in an
effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

         For both types of pre-approval, the Audit Committee will consider
whether such services are consistent with the SEC's rules on auditor
independence. The Audit Committee will also consider whether the Independent
Auditors are best positioned to provide the most effective and efficient
services, for reasons such as its familiarity with the Fund's business, people,
culture, accounting systems, risk profile and other factors, and whether the
service might enhance the Fund's ability to manage or control risk or improve
audit quality. All such factors will be considered as a whole, and no one factor
should necessarily be determinative.

         The Audit Committee is also mindful of the relationship between fees
for audit and non-audit services in deciding whether to pre-approve any such
services and may determine for each fiscal year, the appropriate ratio between
the total amount of fees for Audit, Audit-related and Tax services for the Fund
(including any Audit-related or Tax service fees for Covered Entities that were
subject to pre-approval), and the total amount of fees for certain permissible
non-audit services classified as All Other services for the Fund (including any
such services for Covered Entities subject to pre-approval).

         The appendices to this Policy describe the Audit, Audit-related, Tax
and All Other services that have the general pre-approval of the Audit
Committee. The term of any general pre-approval is 12 months from the date of
pre-approval, unless the Audit Committee considers and provides a different
period and states otherwise. The Audit Committee will annually review and
pre-approve the services that may be provided by the Independent Auditors
without obtaining specific pre-approval from the Audit Committee. The Audit
Committee will add to or subtract from the list of general pre-approved services
from time to time, based on subsequent determinations.

         The purpose of this Policy is to set forth the policy and procedures by
which the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.



- ------------------
(1)      This Joint Audit Committee Audit and Non-Audit Services Pre-Approval
         Policy and Procedures (the "Policy"), amended as of the date above,
         supercedes and replaces all prior versions that may have been amended
         from time to time.
(2)      Terms used in this Policy and not otherwise defined herein shall have
         the meanings as defined in the Joint Audit Committee Charter.



         The Fund's Independent Auditors have reviewed this Policy and believes
that implementation of the Policy will not adversely affect the Independent
Auditors' independence.


2.       DELEGATION

         As provided in the Act and the SEC's rules, the Audit Committee may
delegate either type of pre-approval authority to one or more of its members.
The member to whom such authority is delegated must report, for informational
purposes only, any pre-approval decisions to the Audit Committee at its next
scheduled meeting.


3.       AUDIT SERVICES

         The annual Audit services engagement terms and fees are subject to the
specific pre-approval of the Audit Committee. Audit services include the annual
financial statement audit and other procedures required to be performed by the
Independent Auditors to be able to form an opinion on the Fund's financial
statements. These other procedures include information systems and procedural
reviews and testing performed in order to understand and place reliance on the
systems of internal control, and consultations relating to the audit. The Audit
Committee will monitor the Audit services engagement as necessary, but no less
than on a quarterly basis, and will also approve, if necessary, any changes in
terms, conditions and fees resulting from changes in audit scope, Fund structure
or other items.

         In addition to the annual Audit services engagement approved by the
Audit Committee, the Audit Committee may grant general pre-approval to other
Audit services, which are those services that only the Independent Auditors
reasonably can provide. Other Audit services may include statutory audits and
services associated with SEC registration statements (on Forms N-1A, N-2, N-3,
N-4, etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

         The Audit Committee has pre-approved the Audit services in Appendix
B.1. All other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).


4.       AUDIT-RELATED SERVICES

         Audit-related services are assurance and related services that are
reasonably related to the performance of the audit or review of the Fund's
financial statements or, to the extent they are Covered Services, the Covered
Entities' financial statements, or that are traditionally performed by the
Independent Auditors. Because the Audit Committee believes that the provision of
Audit-related services does not impair the independence of the auditor and is
consistent with the SEC's rules on auditor independence, the Audit Committee may
grant general pre-approval to Audit-related services. Audit-related services
include, among others, accounting consultations related to accounting, financial
reporting or disclosure matters not classified as "Audit services"; assistance
with understanding and implementing new accounting and financial reporting
guidance from rulemaking authorities; agreed-upon or expanded audit procedures
related to accounting and/or billing records required to respond to or comply
with financial, accounting or regulatory reporting matters; and assistance with
internal control reporting requirements under Forms N-SAR and/or N-CSR.

         The Audit Committee has pre-approved the Audit-related services in
Appendix B.2. All other Audit-related services not listed in Appendix B.2 must
be specifically pre-approved by the Audit Committee (or by any member of the
Audit Committee to which pre-approval has been delegated).


5.       TAX SERVICES

         The Audit Committee believes that the Independent Auditors can provide
Tax services to the Fund and, to the extent they are Covered Services, the
Covered Entities, such as tax compliance, tax planning and tax advice without
impairing the auditor's independence, and the SEC has stated that the
Independent Auditors may provide such services. Hence, the Audit Committee
believes it may grant general pre-approval to those Tax services that have
historically been provided by the Independent Auditors, that the Audit Committee
has reviewed and believes would not impair the independence of the Independent
Auditors, and that are consistent with the SEC's rules on auditor independence.
The Audit Committee will not permit the retention of the




Independent Auditors in connection with a transaction initially recommended by
the Independent Auditors, the sole business purpose of which may be tax
avoidance and the tax treatment of which may not be supported in the Internal
Revenue Code and related regulations. The Audit Committee will consult with
Director of Tax or outside counsel to determine that the tax planning and
reporting positions are consistent with this policy.

         Pursuant to the preceding paragraph, the Audit Committee has
pre-approved the Tax Services in Appendix B.3. All Tax services involving large
and complex transactions not listed in Appendix B.3 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated), including tax services proposed to be
provided by the Independent Auditors to any executive officer or
trustee/director/managing general partner of the Fund, in his or her individual
capacity, where such services are paid for by the Fund (generally applicable
only to internally managed investment companies).


6.       ALL OTHER SERVICES

         The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

         The Audit Committee has pre-approved the All Other services in Appendix
B.4. Permissible All Other services not listed in Appendix B.4 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

         A list of the SEC's prohibited non-audit services is attached to this
policy as Appendix B.5. The SEC's rules and relevant guidance should be
consulted to determine the precise definitions of these services and the
applicability of exceptions to certain of the prohibitions.


7.       PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS

         Pre-approval fee levels or budgeted amounts for all services to be
provided by the Independent Auditors will be established annually by the Audit
Committee. Any proposed services exceeding these levels or amounts will require
specific pre-approval by the Audit Committee. The Audit Committee is mindful of
the overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services. For each fiscal year, the Audit
Committee may determine the appropriate ratio between the total amount of fees
for Audit, Audit-related, and Tax services for the Fund (including any
Audit-related or Tax services fees for Covered Entities subject to
pre-approval), and the total amount of fees for certain permissible non-audit
services classified as All Other services for the Fund (including any such
services for Covered Entities subject to pre-approval).


8.       PROCEDURES

         All requests or applications for services to be provided by the
Independent Auditors that do not require specific approval by the Audit
Committee will be submitted to the Fund's Chief Financial Officer and must
include a detailed description of the services to be rendered. The Fund's Chief
Financial Officer will determine whether such services are included within the
list of services that have received the general pre-approval of the Audit
Committee. The Audit Committee will be informed on a timely basis of any such
services rendered by the Independent Auditors. Requests or applications to
provide services that require specific approval by the Audit Committee will be
submitted to the Audit Committee by both the Independent Auditors and the Fund's
Chief Financial Officer, and must include a joint statement as to whether, in
their view, the request or application is consistent with the SEC's rules on
auditor independence.

         The Audit Committee has designated the Fund's Chief Financial Officer
to monitor the performance of all services provided by the Independent Auditors
and to determine whether such services are in compliance with this Policy. The
Fund's Chief Financial Officer will report to the Audit Committee on a periodic
basis on the results of its monitoring. A sample report is included as Appendix
B.7. Both the Fund's Chief Financial Officer and management will immediately
report to the chairman of the Audit Committee any breach of this Policy that
comes to the attention of the Fund's Chief Financial Officer or any member of
