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 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. See footnote 3 in the Notes
to Financial Statements for additional information. 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)

Fund Report

FOR THE 12-MONTH PERIOD ENDED AUGUST 31, 2005

Van Kampen Corporate Bond Fund is managed by the Adviser's Taxable Fixed Income
team.(1) Members of the team include David S. Horowitz, Managing Director of the
Adviser and Gerhardt Herbert, Executive Director of the Adviser.

MARKET CONDITIONS

Throughout the reporting period, the Federal Open Market Committee (the "Fed")
continued the tightening cycle it began in June of 2004. In a series of eight 25
basis-point increases, the Fed brought the federal funds target rate from 1.50
percent at the start of the reporting period to 3.50 percent at the close.
Despite these steady increases, most U.S. Treasury yields see-sawed throughout
the period. Overall, the yield curve flattened as the yields of short-and
intermediate-term Treasuries rose while those of long-term Treasuries declined.

Within the corporate bond market, the period was generally uneventful until the
first quarter of 2005, when General Motors reported lower-than-expected
earnings. Shortly thereafter, the beleaguered auto manufacturer saw its debt
downgraded to below-investment grade, alongside that of Ford Motor and their
financial subsidiaries. Although the travails of the auto industry gave
investors pause, generally good corporate earnings announcements and positive
economic news helped the market regain its bearings in the following months. The
utilities sector garnered the highest gains during the annual period, while the
financials sector posted the lowest returns.

As the end of the period approached, it was apparent that the full effects of
the Fed's actions had yet to ripple through the economy. For the most part,
concerns about rising energy prices and inflation as well as faltering growth
had muted the impact of the Fed's rate increases, and the market reflected
neither underlying fundamental trends nor a more likely course for Fed policy.
Moreover, the final days of the reporting period brought heightened uncertainty
and anxiety as Hurricane Katrina unleashed catastrophic devastation to the Gulf
Coast. While the long-term economic impact remained immeasurable, the immediate
economic impact was most evident in the energy sector, as gasoline and natural
gas prices soared.

PERFORMANCE ANALYSIS

The fund returned 5.79 percent for the 12 months ended August 31, 2005, (Class A
shares, unadjusted for sales charge). In comparison, the fund's benchmarks, the
Lehman Brothers Corporate Bond Index and the Lipper Corporate BBB-Rated Index,
returned 4.9 percent and 5.23 percent for the period, respectively.

THE PERFORMANCE FOR THE THREE 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.

The fund's emphasis on medium-quality investment grade credits enhanced
performance during the period. As investors sought income, medium-quality
credits outpaced higher-quality bonds. (Bonds with higher credit qualities
typically offer lower yields.) Additionally, the fund's performance relative to
the Lehman index benefited from underweightings in the energy sector and the
banking and finance sector.

The fund's overall interest rate strategy produced mixed results for the period.
The low level of interest rates across the yield curve at the beginning of the
period led us to conclude that they had little room to fall. As a result, we
kept the fund's overall interest rate exposure below that of its benchmarks.
This posture was unfavorable to the fund's returns early in the period when the
market rallied, but was more beneficial during periods of rising rates,
especially in the later half of the period.

There is no guarantee that any sectors mentioned will continue to perform well
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 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 3/1/05 - 8/31/05.

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.

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 25, 2005, 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. Finally, the Board considered materials it had received in
approving a change in the advisory fee rate effective November 1, 2004. 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,

 10


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 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, a performance committee of 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

                                                                              11


together by the investment adviser with the oversight of a special ad hoc
committee of the Board. The trustees discuss with the investment adviser its
revenues and expenses, including among 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.

VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2005

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 distribution of the Fund's Class B, Class C, and Class I Shares
commenced on September 28, 1992, August 30, 1993, and August 12, 2005,
respectively.

    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 obtained 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.

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

                                                                              29


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2005 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 current 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>

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 years ended August 31,
2005 and 2004 was as follows:

<Table>
<Caption>
                                                                 2005           2004
                                                                       
Distribution paid from:
  Ordinary Income...........................................  $27,486,058    $25,453,701
  Return of Capital.........................................           --        204,800
                                                              -----------    -----------
                                                              $27,486,058    $25,658,501
                                                              ===========    ===========
</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 relating to
distributions in excess of book income for the fiscal year 2005

 30


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2005 continued

totaling $556,619 was reclassified to capital from accumulated undistributed net
investment income. In addition, permanent book and tax differences of $93
related to the Fund's investments in other regulated investment companies and
$99,410 related to fee income received on tender offers were reclassified from
accumulated undistributed net investment income to accumulated net realized
loss. Additionally, a permanent book and tax difference of $20,475 related to
the recognition of net realized losses on paydowns of mortgage pool obligations
and $1,659,550 related to book to tax amortization differences were reclassified
from accumulated undistributed net investment income to accumulated net realized
loss.

    Net realized gains or losses may differ for financial and tax reporting
purposes as a result of gains or losses recognized for tax purposes on open
futures transactions at August 31, 2005 and the deferral of losses relating to
wash sales transactions.

F. EXPENSE REDUCTIONS During the year ended August 31, 2005, the Fund's custody
fee was reduced by $29,388 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:

<Table>

First $500 million..........................................     .42%
Next $750 million...........................................     .35%

million, and .35% for any average daily net assets greater than $350 million.

    For the year ended August 31, 2005, the Fund recognized expenses of
approximately $41,100 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, 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.

provides compliance services to the Fund. The costs of these services are
allocated to each fund. For the year ended August 31, 2005, the Fund recognized

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

    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 $81,400 are
included in "Other" assets on the Statement of Assets and Liabilities at August
31, 2005. 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, 2005, Van Kampen, as Distributor for the Fund,
received commissions on sales of the Fund's Class A Shares of approximately
$663,800 and CDSC on redeemed shares of approximately $239,000. Sales charges do
not represent expenses of the Fund.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $472,313,339 and $342,351,297,
respectively.

5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index. The 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
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

 34


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2005 continued

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, 2005, were
as follows:

Outstanding at August 31, 2005..............................    2,335

</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, as in the case of the Fund, 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 swaps on the Statement 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.

6. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively, the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and the maintenance of shareholder
accounts with respect to such classes of shares.

    Annual fees under the Plans 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 are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid

                                                                              35


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2005 continued

monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25%
of the annual fees are paid quarterly. The amount of distribution expenses
incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") was
approximately $1,662,700 and $0 for Class B and Class C Shares, respectively.
These amounts may be recovered from future payments under the plan or CDSC. To
the extent the unreimbursed receivable has been fully recovered, any excess
12b-1 fees will be refunded to the Fund on a quarterly basis.

    Included in the fees for the year ended August 31, 2005, are payments
retained by Van Kampen of approximately $985,100 and payments made to Morgan
Stanley DW Inc., an affiliate of the Adviser, of approximately $221,500.

7. 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 recently
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.
Plaintiffs have filed a Motion for Leave to file a Supplemental Pleading that
would, among other things, expand the allegations and alleged class.

    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. Plaintiff has sought leave to 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.

 36


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- AUGUST 31, 2005 continued

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of litigation, and no provision has been made
in the Fund's financial statements for the effect, if any, of these matters.

8. 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.

                                                                              37


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, 2005, 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, 2005, 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, 2005, 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.

Item 2.  Code of Ethics.

(a) The Fund has adopted a code of ethics (the "Code of Ethics") that applies to
its principal executive officer, principal financial officer, principal
accounting officer or controller, or persons performing similar functions,
regardless of whether these individuals are employed by the Fund or a third
party.

(b) No information need be disclosed pursuant to this paragraph.

(c) The Fund has amended its Code of Ethics during the period covered by the
shareholder report presented in Item 1 hereto to delete from the end of the
following paragraph on page 2 of the Code the phrase "to the detriment of the
Fund.":

"Each Covered Officer must not use his personal influence or personal
relationship improperly to influence investment decisions or financial reporting
by the Fund whereby the Covered Officer would benefit personally (directly or
indirectly)."

Further, due to personnel changes at the Adviser, the list of Covered Officers
set forth in Exhibit B and the General Counsel designee to whom questions about
the application of the Code should be referred in Exhibit C were amended during
the period. Exhibit B was then amended again in March 2005 and a third time in
August 2005 and a fourth time in September 2005. All four editions of Exhibit B
are attached. Additionally, Exhibit B was amended to remove Mitchell M. Merin as
a covered officer.

(d) Not applicable.

(e) Not applicable.

(f)

    (1) The Fund's Code of Ethics is attached hereto as Exhibit 12A.
    (2) Not applicable.
    (3) Not applicable.

Item 3. Audit Committee Financial Expert.

The Fund's Board of Trustees has determined that it has two "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees: Jerry Choate and R. Craig Kennedy. Under applicable
securities laws, a person who is determined to be an audit committee financial
expert will not be deemed an "expert" for any purpose, including without
limitation for the purposes of Section 11 of the Securities Act of 1933, as a
result of being designated or identified as an audit committee financial expert.
The designation or identification of a person as an audit committee financial
expert does not impose on such person any duties, obligations, or liabilities
that are greater than the duties, obligations, and liabilities imposed on such
person as a member of the audit committee and Board of Trustees in the absence
of such designation or identification.

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

AS ADOPTED JULY 23, 2003 AND AMENDED MAY 26, 20041


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. 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
management.



9.  ADDITIONAL REQUIREMENTS

    The Audit Committee has determined to take additional measures on an annual
basis to meet its responsibility to oversee the work of the Independent Auditors
and to assure the auditor's independence from the Fund, such as reviewing a
formal written statement from the Independent Auditors delineating all
relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.


10. COVERED ENTITIES

    Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
non-audit service contracts entered into on or after May 6, 2003, the Fund's
audit committee must pre-approve non-audit services provided not only to the
Fund but also to the Covered Entities if the engagements relate directly to the
operations and financial reporting of the Fund. This list of Covered Entities
