       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that the fund will achieve its investment
       objective. The fund is subject to market risk, which is the possibility

Past performance is no guarantee of future results and current performance may
be lower or higher than the figures shown. For more up-to-date information,
including 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.

As a result of recent market activity, current performance may vary from the
figures shown. 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 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. Figures shown above assume
reinvestment of all dividends and capital gains. SEC yield is a calculation for
determining the amount of portfolio income, excluding non-income items as
prescribed by the SEC. Yields are subject to change.

Lehman Brothers Credit Bond Index is a market-weighted index of investment-grade
corporate fixed-rate debt issues with maturities of one year or more. Lipper
Corporate BBB-Rated Index is an index of funds with similar investment
objectives as this fund. Indexes do not include any expenses, fees or sales
charges, which would lower performance. Indexes are unmanaged and should not be
considered an investment.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED FEBRUARY 29, 2004

Van Kampen Corporate Bond Fund is managed by the adviser's Taxable Fixed Income
team. Current members of the team include Sheila Finnerty, Managing Director,
and David S. Horowitz and Gordon W. Loery, Executive Directors.(1)

MARKET CONDITIONS

Over the six-month reporting period, the overall environment for investment-
grade corporate bonds remained generally positive. Weaker economic reports in
September caused some investors to retreat to Treasuries, but this move was
short-lived. In the fourth quarter of 2003, data once again indicated a strong
revival of economic activity. This boosted investor confidence in further
economic growth and improvement in corporate earnings, spurring demand for
corporate bonds over lower-yielding Treasuries.

Virtually all areas of the corporate market benefited, though the impact was
greatest among lower-rated corporate securities. Non-investment grade high-yield
bonds outperformed their higher-rated counterparts. Within the investment-grade
realm, BBB rated bonds offered the strongest performance. Investors came to
favor these lower-rated bonds not only for their higher yields--which are
particularly attractive in a low-rate environment--but also for their capital
appreciation potential in the face of a strengthening economic environment.

Continuing a trend seen earlier in 2003, the sectors and individual bonds that
had been among the most beaten down in 2002 offered some of the strongest
performance over the period. These included bonds in the technology,
telecommunications, and cable sectors, all of which benefited from investors'
perceptions of their reasonable valuations, improving corporate governance, and
recovering earnings prospects. Weaker-performing bonds, however, came from more
stable, steady-growth areas of the economy, such as food producers and drug
makers.

Yield spreads--the difference in yield between corporate bonds and similar-
maturity Treasuries--have contracted significantly as corporate bonds have
rebounded from their previously depressed levels. As a result, individual bond
selection--rather than exposure to broader market sectors--has become a crucial
factor in performance. It appears that the "easy money" that could be made in
the earlier days of the corporate bond recovery is now past.

The Federal Reserve kept short-term interest rates low throughout the period.
Market interest rates generally declined over the six months after their run-up
during the summer of 2003.

PERFORMANCE ANALYSIS

The fund returned 6.39 percent for the reporting period, yet slightly
underperformed its benchmark indexes, the Lehman Brothers Credit Bond Index and
the Lipper Corporate BBB-Rated Index. (Performance is for Class A shares,
unadjusted for sales charge. See table below.)

The fund was generally positioned to benefit from a recovering economy, an
approach that for the most part contributed positively to performance. Our
significant allocation to BBB rated bonds--those in the lowest tier of
investment-grade debt--helped to boost the fund's returns as this sector of the
market outperformed higher-rated bonds.

In keeping with our expectation of an improving economic environment, we favored
bonds from those sectors we believed were positioned to benefit significantly
from that turnaround. Among the areas we overweighted relative to the benchmarks
over the past six months were financials, transportation, utilities, and energy.

We also continued to keep the fund's duration (its sensitivity to interest-rate
changes) shorter than that of its benchmarks. We believe this positioning was
prudent, given the signs of strength in the economy. As the economy continues to
improve, in time the Federal Reserve is likely to act to increase rates--and in
that case, a shorter duration would be beneficial to performance. However, the
Federal Reserve did not take such action during the period, and in fact market
interest rates fell slightly for the six months. As a result, our duration
positioning hindered the fund's performance somewhat.

In keeping with our strategy during the last reporting period, we maintained our
underweighted position in bonds in the five- to 20-year maturity range. In our
opinion, many bonds in this part of the yield curve were simply too expensive.
This strategy helped to keep price risk at bay and to keep the fund's duration
shorter than that of the benchmarks. Given that the Federal Reserve may become
more active later in the year--perhaps after the Presidential
election--maintaining our shorter duration stance seems appropriate at this
point.

After such a strong period for corporate bonds, returns going forward are likely
to be driven primarily by bond coupons, with little contribution from capital
appreciation. As a result, returns are likely to be more moderate going forward.

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 and
index definitions.

                                                                               3


That said, we believe that the emerging economic recovery makes this a
reasonable time to hold corporate debt. Among the bond sectors we believe may
present opportunities in this environment are transportation, health care,
utilities, forest products, and energy. We will continue to maintain a well-
diversified portfolio, with exposure to a wide variety of sectors and individual
issues. In a market in which individual bond selection may play a driving role
in returns, we will continue to combine top-down macroeconomic considerations
with bottom-up security research.

There is no guarantee the securities mentioned will continue to perform well or
be held by the fund in the future.

VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 29, 2004 (UNAUDITED)

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 and Class C Shares commenced on
September 28, 1992 and August 30, 1993, 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 accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION 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. Equity securities
traded on NASDAQ are valued at the NASDAQ Official Closing Price. Listed and
unlisted securities for which the last sales price is not available are valued
at the mean of the bid and asked prices. For those securities where quotations
or prices are not available as noted above, valuations are determined in
accordance with procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange in which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

    The Fund invests 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. 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 transfer agency costs which are unique to each
class of shares.

                                                                              21

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
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, 2003, the Fund had an accumulated capital loss carryforward
for tax purposes of $18,503,503 which will expire between August 31, 2008 and
2011.

    At February 29, 2004, the cost and related gross unrealized appreciation and
depreciation are as follows:

<Table>

</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 2003 was as follows:

                                                                ===========

basis were as follows:

Undistributed ordinary income...............................    $288,566
</Table>

    Net realized gains or losses may differ for financial and tax reporting
purposes as a result of the deferral of losses relating to wash sale
transactions.

F. EXPENSE REDUCTIONS During the six months ended February 29, 2004, the Fund's
custody fee was reduced by $1,362 as a result of credits earned on cash
balances.

services to the Fund. The Adviser allocates the cost of such services to each
fund. For the six months ended February 29, 2004, the Fund recognized expenses
of approximately $19,400 representing Van Kampen Investments Inc.'s or its
affiliates (collectively "Van Kampen") cost of providing accounting services to
the Fund, which are reported as part of "Other" expenses in the Statement of
Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
February 29, 2004, the Fund recognized expenses of approximately $423,300
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 $73,500 are
included in "Other" assets on the Statement of Assets and Liabilities at
February 29, 2004. 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.

                                                                              23

    For the six months ended February 29, 2004, Van Kampen, as Distributor for
the Fund, received commissions on sales of the Fund's Class A Shares of
approximately $192,400 and CDSC on redeemed shares of approximately $157,900.
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 $105,734,310 and $105,603,564,
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 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

                                                                              25

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

    During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in futures on U.S. Treasury Notes. Upon entering into futures
contracts, the Fund maintains an amount of cash or liquid securities with a
value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the statement
of Assets and Liabilities.

    Transactions in futures contracts for the six months ended February 29,
2004, were as follows:

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 0.25% of Class A average daily net
assets and 1.00% each for Class B and Class C average daily net assets are
accrued daily. The amount of distribution expenses incurred by Van Kampen and
not yet reimbursed ("unreimbursed receivable") was approximately $2,816,600 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, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in the fees for the six months ended February 29, 2004, are
payments retained by Van Kampen of approximately $579,300 and payments made to
Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $91,800.

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 recently filed, similar class action complaints. One
of the actions also names the individual Trustees of the Van Kampen funds as
defendants. These complaints generally allege that defendants, including the
Fund, 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 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 complaints seek, among other things, unspecified compensatory damages,
rescissionary damages, fees and costs. The defendants intend to move to dismiss
these actions and otherwise vigorously to defend them. While the Fund believes
that it has meritorious defenses, the ultimate outcome of these matters is not
presently determinable at this early stage of the litigation, and no provision
has been made in the Fund's financial statements for the effect, if any, of
these matters.

                                                                              27
