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, (iii)
qualified state tuition plan (529 plan) accounts, (iv) institutional clients
with assets of at least $1 million and (v) certain Van Kampen investment
companies. 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.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED FEBRUARY 29, 2008

MARKET CONDITIONS

The market was quite volatile throughout the six-month reporting period as the
residential housing downturn and contagion from the subprime mortgage market
persisted, leading to an ongoing contraction in liquidity and tighter credit
conditions. At the same time, weaker economic indicators released in the last
months of 2007 and early 2008 signaled the likelihood of an impending recession.
Together, these factors led to a prolonged flight to quality as investors
shunned riskier assets.

The Federal Open Market Committee (the "Fed") took various steps to add
liquidity to the financial system in an attempt to ease the ensuing liquidity
crisis and boost the economy, including five reductions in the target federal
funds rate, bringing the rate to 3.0 percent as of February 29, 2008. Although
U.S. Treasury yields fluctuated, the flight to quality pushed Treasury prices
generally higher and yields lower during the period, helping Treasuries to
outperform other fixed income sectors. The short end of the yield curve
experienced the most pronounced declines as Fed rate cuts drove yields there
lower, causing the curve to end the period steeper.

Within the corporate sector credit spreads widened sharply, bringing spread
levels closer to historical averages. Financials were particularly hard hit as
writedowns on mortgage related securities by major banks and Wall Street firms
hurt the sector's performance. Given the risk-averse environment, higher rated
securities outperformed those with lower ratings. Within the investment-grade
corporate sector, AAA issues outpaced middle investment grade issues, and
longer-term issues outperformed shorter-dated issues.

The mortgage-backed security (MBS) sector continued to struggle, with non-
agency mortgages experiencing the greatest declines. Much of the growth in
mortgage issuance in recent years has been in these non-traditional mortgages,
which offered more lenient borrowing terms and were thus available to a broader
set of borrowers. While this helped fuel both the housing boom and a vibrant
secondary market for these non-agency mortgages, the subprime meltdown cast a
pall across the entire non-agency sector, with little regard for whether or not
the securities or loans in question were subprime or prime. The result was a
further reduction in mortgage market liquidity, as well as a sharp diminishment
in the availability of non-conforming mortgage loans to the general public.

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.

One of the positive contributors to the Fund's performance during the period was
an underweighted allocation to corporate bonds relative to that of the Lehman
Brothers Corporate Bond Index as widening credit spreads were detrimental to the
sector's performance. While we are looking for areas to take advantage of recent
spread widening and add to corporate positions, we are cautious as we believe
the credit market remains vulnerable to potential credit downgrades and further
weakening of the economy.

The Fund's yield curve positioning was also beneficial. Here, we maintained an
underweight relative to the Lehman Brothers Corporate Bond Index in longer dated
issues and an overweight to intermediate dated issues. This strategy helped
enhance returns as the spread between intermediate- and long-dated yields
widened and the curve steepened during the period.

The Fund has an allocation to mortgage securities, which are not represented in
the Lehman Brothers Corporate Bond Index. These holdings, particularly non-
agency mortgage securities, commercial mortgage-backed securities and asset-
backed securities, detracted from relative performance for the period. As a
result of defaults in the subprime market, spreads on all residential and
commercial mortgage-backed products moved wider and market liquidity for these
types of products severely diminished. Although the Fund's holdings of
non-agency MBS underperformed, we note that the majority of them are backed by
prime and near-prime borrowers with good credit scores and favorable
loan-to-value ratios. Asset-backed securities, especially those backed by home
equity lines of credit, were hurt as well.

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.

       Each Van Kampen fund provides a complete schedule of portfolio holdings
       in its semiannual and annual reports within 60 days of the end of the
       fund's second and fourth fiscal quarters. The semiannual reports and the

       mailings to the same address. The Fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The Fund's prospectuses

       otherwise. You can request multiple copies of these documents by either

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the Fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the
       Securities and Exchange Commission's Web site at http://www.sec.gov.

       You may obtain information regarding how the Fund voted proxies relating
       to portfolio securities during the most recent twelve-month period ended
       June 30 without charge by visiting our Web site at www.vankampen.com.
       This information is also available on the Securities and Exchange
       Commission's Web site at http://www.sec.gov.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class 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 9/1/07 - 2/29/08.

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
cost would have been higher.

VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 29, 2008 (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. Capital appreciation is a secondary objective that is
sought only when consistent with the Fund's primary investment objective. 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 sale price is not available are valued at the mean
of the last reported bid and asked prices. For those securities where quotations
or prices are not readily available, 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. 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. 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 -- FEBRUARY 29, 2008 (UNAUDITED) continued

commitments until payment is made. At February 29, 2008, the Fund had no
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 adopted the provisions of the Financial Accounting Standards Board ("FASB")
Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on
February 29, 2008. FIN 48 sets forth a minimum threshold for financial statement
recognition of the benefit of a tax position taken or expected to be taken in a
tax return. The implementation of FIN 48 did not result in any unrecognized tax
benefits in the accompanying financial statements. If applicable, the Fund
recognizes interest accrued related to unrecognized tax benefits in "Interest
Expense" and penalties in "Other" expenses on the Statement of Operations. The
Fund files tax returns with the U.S. Internal Revenue Service and various
states. Generally, each of the tax years in the four year period ended August
31, 2007, remains subject to examination by taxing authorities.

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. During the prior fiscal year, the Fund utilized capital losses carried
forward of $917,462. At August 31, 2007, the Fund had an accumulated capital
loss carryforward for tax purposes of $5,440,078, which will expire according to
the following schedule:

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 at least 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.

    The tax character of distributions paid during the year ended August 31,
2007 was as follows:

<Table>

  Ordinary income...........................................    $37,550,290
  Long-term capital gain....................................            -0-

                                                                $37,550,290
                                                                ===========
</Table>

    As of August 31, 2007, the component of distributable earnings on a tax
basis was as follows:

<Table>
                                                             
Undistributed ordinary income...............................    $213,392
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of the deferral of losses relating to wash sale
transactions, or gains or losses recognized on securities for tax purposes, but
not for book purposes.

F. CREDITS EARNED ON CASH BALANCES During the six months ended February 29,
2008, the Fund's custody fee was reduced by $12,788 as a result of credits
earned on cash balances.

G. FOREIGN CURRENCY TRANSLATION Assets and liabilities denominated in foreign
currencies and commitments under forward foreign currency contracts are
translated into U.S. dollars at the mean of the quoted bid and asked prices of
such currencies against the U.S. dollar. Purchases and sales of portfolio
securities are translated at the rate of exchange prevailing when such
securities were acquired or sold. Realized gain and loss on foreign currency
transactions on the Statement of Operations includes the net realized amount
from the sale of foreign currency, the amount realized between trade date and
settlement date on securities transactions and the foreign currency portion of
gains and losses on the sale of securities. Income and expenses are translated
at rates prevailing when accrued.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Flom LLP, of which a trustee of the Fund is a partner of such firm and he and
his law firm provide legal services as legal counsel to the Fund.

    Under separate Accounting Services and Chief Compliance Officer (CCO)
Employment agreements, the Adviser provides accounting services and the CCO
provides compliance services to the Fund. The costs of these services are
allocated to each fund. For the six months ended February 29, 2008, the Fund
recognized expenses of approximately $28,200 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 "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
February 29, 2008, the Fund recognized expenses of approximately $666,500
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
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 $105,468 are included in
"Other" assets on the Statement of Assets and Liabilities at February 29, 2008.
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 six months ended February 29, 2008, Van Kampen, as Distributor for
the Fund, received commissions on sales of the Fund's Class A Shares of
approximately $186,200 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $80,100. Sales charges do not represent expenses of the
Fund.

                                                                              33

4. REDEMPTION FEE

The Fund will assess 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 and allocated on a pro rata basis to
each class of shares. For the six months ended February 29, 2008, the Fund
received redemption fees of approximately $900, which are reported as part of
"Cost of Shares Repurchased" on 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 and U.S. Government securities, were
$166,139,965 and $140,019,545 respectively. The cost of purchases and proceeds
from sales of long-term U.S. Government securities, including paydowns on
mortgage-backed securities, for the period were $93,121,761 and $142,156,554,
respectively.

6. MORTGAGE BACKED SECURITIES

The Fund may invest in various types of Mortgage Backed Securities. A Mortgage
Backed Security (MBS) is a pass-through security created by pooling mortgages
and selling

 34


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 29, 2008 (UNAUDITED) continued

participations in the principal and interest payments received from borrowers.
Most of these securities are guaranteed by federally sponsored
agencies -- Government National Mortgage Association (GNMA), Federal National
Mortgage Association (FNMA) or Federal Home Loan Mortgage Corporation (FHLMC). A
Collateralized Mortgage Obligation (CMO) is a bond which is collateralized by a
pool of MBS's.

    These securities derive their value from or represent interests in a pool of
mortgages, or mortgage securities. Mortgage securities are subject to prepayment
risk -- the risk that, as mortgage interest rates fall, borrowers will refinance
and "prepay" principal. A fund holding mortgage securities that are experiencing
prepayments will have to reinvest these payments at lower prevailing interest
rates. On the other hand, when interest rates rise, borrowers are less likely to
refinance resulting in lower prepayments. This can effectively extend the
maturity of a fund's mortgage securities resulting in greater price volatility.
It can be difficult to measure precisely the remaining life of a mortgage
security or the average life of a portfolio of such securities.

    To the extent a fund invests in mortgage securities offered by
non-governmental issuers, such as commercial banks, savings and loan
institutions, private mortgage insurance companies, mortgage bankers and other
secondary market issuers, the Fund may be subject to additional risks. Timely
payment of interest and principal of non-governmental issuers are supported by
various forms of private insurance or guarantees, including individual loan,
title, pool and hazard insurance purchased by the issuer. There can be no
assurance that the private insurers can meet their obligations under the
policies.

    An unexpectedly high rate of defaults on the mortgages held by a mortgage
pool may adversely affect the value of a mortgage backed security and could
result in losses to a Fund. The risk of such defaults is generally higher in the
case of mortgage pools that include subprime mortgages. Subprime mortgages refer
to loans made to borrowers with weakened credit histories or with a lower
capacity to make timely payment on their mortgages.

7. 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 appreciation/ depreciation. Upon disposition, a
realized gain or loss is recognized accordingly, except when taking delivery of
a security underlying a futures contract. In these instances, 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

                                                                              35


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 29, 2008 (UNAUDITED) continued

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,
2008, were as follows:

Outstanding at February 29, 2008............................      3,135
                                                                 ======
</Table>

B. SWAP CONTRACTS 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 credit default swaps 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 Statement 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 on the
Statement of Operations. Payments received or made upon entering into a credit
default swap contract, if any, are recorded as realized gain or loss on the
Statement of Operations upon termination or maturity of the swap. 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.

    The Fund may also enter into interest rate swaps primarily to preserve a
return or spread on a particular investment or portion of its portfolio, as a
duration management technique or to protect against any increase in the price of
securities the Fund anticipates purchasing at a later date. Interest rate swaps
are contractual agreements to exchange periodic interest payment streams
calculated on a predetermined notional principal amount. Interest rate swaps
generally involve one party paying a fixed interest rate and the other party
paying a variable rate. The Fund will usually enter into interest rate swaps on
a net basis, i.e., the two payment streams are netted out in a cash settlement
on the payment date or dates specified in the instrument, with

 36


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 29, 2008 (UNAUDITED) continued

the Fund receiving or paying, as the case may be, only the net amount of the two
payments. The Fund accrues the net amount with respect to each interest rate
swap on a daily basis. This net amount is recorded within unrealized
appreciation/depreciation on swap contracts. Upon cash settlement of the
periodic payments, the net amount is recorded as realized gain/loss on swap
contracts on the Statement of Operations. Risks may arise as a result of the
potential inability of the counterparties to meet the terms of their contracts.

    If there is a default by the counterparty to a swap agreement, the Fund will
have contractual remedies pursuant to the agreements related to the transaction.
Counterparties are required to pledge collateral daily (based on the valuation
of each swap) on behalf of the Fund with a value approximately equal to the
amount of any unrealized gain. Cash collateral, when received by the Fund, is
recorded with an offsetting liability shown on the Statement of Assets and
Liabilities. Reciprocally, when the Fund has an unrealized loss on a swap
contract, the Fund has instructed the custodian to pledge cash or liquid
securities as collateral with a value approximately equal to the amount of the
unrealized loss. Collateral pledges are monitored and subsequently adjusted if
and when the swap valuations fluctuate. Restricted cash, if any, for segregating
purposes is shown on the Statement of Assets and Liabilities.

8. 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 $400,700 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.

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. ACCOUNTING PRONOUNCEMENT

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. As of February 29, 2008, the Adviser does not believe the adoption
of SFAS 157 will impact the amounts reported in the financial statements,
however, additional disclosures will be required about the inputs used to
develop the measurements of fair value and the effect of certain measurements
reported on the Statement of Operations for a fiscal period.

                                                                              37
