 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,

The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
                  nearly four generations of investment-management experience,
                  we've been around long enough to understand that by investing
with Van Kampen you're entrusting us with much more than your money. Your
investments may help make it possible to afford your next house, keep up with
rising college costs, or enjoy a comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]
Richard F. Powers, III
President and CEO
Van Kampen Investments

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

    N/A = Not Applicable

(1) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge (4.75% for Class A Shares) or
    contingent deferred sales charge ("CDSC"). On purchases of Class A Shares of
    $1 million or more, a CDSC of 1% may be imposed on certain redemptions made
    within one year of purchase. Returns for Class B Shares are calculated
    without the effect of the maximum 4% CDSC, charged on certain redemptions
    made within one year of purchase and declining to 0% after the sixth year.
    Returns for Class C Shares are calculated without the effect of the maximum
    1% CDSC, charged on certain redemptions made within one year of purchase. If
    the sales charges were included, total returns would be lower. These returns
    do include Rule 12b-1 fees of up to .25% for Class A Shares and 1% for Class
    B and Class C Shares.

(2) Standardized total return. Assumes reinvestment of all distributions for the
    period and includes payment of the maximum sales charge (4.75% for Class A
    Shares) or contingent deferred sales charge ("CDSC") for Class B and C
    Shares and Rule 12b-1 fee. On purchases of Class A Shares of $1 million or
    more, a CDSC of 1% may be imposed on certain redemptions made within one
    year of purchase. Returns for Class B Shares are calculated with the effect
    of the maximum 4% CDSC, charged on certain redemptions made within one year
    of purchase and declining to 0% after the sixth year. Returns for Class C
    Shares are calculated with the effect of the maximum 1% CDSC, charged on
    certain redemptions made within one year of purchase. The Rule 12b-1 fee for
    Class A Shares is up to .25% and for Class B and Class C Shares is 1%.

(3) The total return reflects the conversion of Class B Shares into Class A
    Shares six year after the end of the calendar month in which the shares were
    purchased. See Footnote 3 in the Notes to Financial Statements for
    additional information.

(4) Distribution rate represents the monthly annualized distributions of the
    Fund at the end of the period and not the earnings of the Fund.

(5) SEC Yield is a standardized calculation prescribed by the Securities and
    Exchange Commission for determining the amount of net income a portfolio
    should theoretically generate for the 30-day period ending September 30,
    2000. Had certain expenses of the Fund not been assumed by Van Kampen, the
    SEC Yield would have been 11.50%, 11.29%, and 11.29% for Classes A, B and C,
    respectively, and the total returns would have been lower.

    An investment in the Fund is subject to investment risks, and you could lose
    money on your investment in the Fund. Please review the Risk/Return Summary
    of the Prospectus for further details on investment risks. Fund shares, when
    redeemed, may be worth more or less than their original cost. Past
    performance is no guarantee of future results. Investment return and net
    asset value will fluctuate with market conditions.

    Investing in high-yield, lower-rated securities involves certain risks,
    which may include the potential for greater sensitivity to general economic
    downturns and greater market price volatility.

Q&A WITH YOUR PORTFOLIO MANAGERS
WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF THE VAN
KAMPEN HIGH YIELD FUND ABOUT THE KEY EVENTS AND ECONOMIC
FORCES THAT SHAPED THE MARKETS AND INFLUENCED THE FUND'S
RETURN DURING THE PAST SIX MONTHS. THE TEAM IS LED BY
ROBERT J. HICKEY, SENIOR PORTFOLIO MANAGER, WHO HAS
MANAGED THE FUND SINCE FEBRUARY 1998 AND WORKED IN THE
INVESTMENT INDUSTRY SINCE 1988. HE IS JOINED BY PORTFOLIO
MANAGER PETER E. EHRET. THE FOLLOWING DISCUSSION REFLECTS
THEIR VIEWS ON THE FUND'S PERFORMANCE.

Q   HOW WOULD YOU CHARACTERIZE
    THE MARKET ENVIRONMENT OF THE LAST SIX MONTHS AND HOW DID IT AFFECT THE
    HIGH-YIELD MARKET AND FUND PERFORMANCE?

A   As the economy picked up
momentum, the Federal Reserve Board continued its policy of raising interest
rates to fight inflationary risks. As interest rates rose, yield spreads between
Treasuries and other types of bonds, including high-yield/high-risk bonds,
widened dramatically, putting downward pressure on high-yield bond prices.

    Throughout the past six months, we've seen steady consumer activity, a
strong U.S. dollar, and inflation hovering around 2 to 3 percent. Given the
current low-inflation environment, many companies have been unable to raise the
prices of their outputs. At the same time, labor and borrowing costs have crept
up with rising interest rates. The result has been reduced earnings for some
companies--especially those carrying a higher debt load--and an increase in
defaults.

    In addition, fixed-income funds as a whole experienced outflows throughout
much of the reporting period. These redemptions were fueled in part by concerns
about defaults and rising interest rates. And despite the deceleration of the
stock market in recent months, we continued to see a general investor preference
for equities. These factors all contributed to reduced overall demand for high-
yield securities. This reduced demand, coupled with the higher cost of capital
for high-yield debt issuers, led to an extremely low supply of high-yield
bonds--creating more demand/supply equilibrium in the market than we have seen
in many months.

    The fund did experience some outflows in April and early May. However, this
trend reversed in June and July as consumer confidence in the market returned,
money flowed back into the high-yield market, and prices

                                        7
<PAGE>   9

rebounded. The momentum of the high-yield market reversed again in August as a
rash of negative earnings announcements in the telecommunications sector hit the
market, negatively impacting the fund's performance at the end of the reporting
period.

    For the six-months ended September 30, 2000, the fund posted a total return
of -1.20% percent (Class A shares at net asset value; if the maximum sales
charge of 4.75 percent were included, the return would be lower). By comparison,
the Credit Suisse First Boston High Yield Index returned 1.52 percent for the
same period. This broad-based, unmanaged index reflects the general performance
of a wide range of selected bonds within the public high-yield debt market, but
it does not reflect any commissions or fees that would be paid by an investor
purchasing the securities it represents. Such costs would lower its performance.
It is not possible to invest directly in an index. Of course, past performance
is no guarantee of future results. As a result of recent market activity,
current performance may vary from the figures shown. Please refer to the chart
and footnotes on page 4 for additional fund performance results.

Q   CAN YOU ELABORATE ON THE FUND'S
    SECTOR ALLOCATIONS AND HOW THESE WERE AFFECTED BY THE HIGH-YIELD MARKET
    ENVIRONMENT?

A   As mentioned earlier, the end of
the reporting period was especially turbulent for the telecommunications
industry. Negative earnings announcements within this sector, predominantly by
wired-line phone companies, led to repeated earnings adjustments and reduced
market interest. ICG Holdings bonds, in particular, were battered after the
company endured three consecutive earnings adjustments and announced financial
and operating problems. As a result, the fund's performance was hampered by its
higher weighting in telecommunications.

    The U.S. dollar value has been very strong versus other currencies
throughout the reporting period. For companies with operations abroad, however,
a strong U.S. dollar had a depreciating effect upon their earnings streams as
this money was converted from its foreign-currency denomination back into U.S.
dollars. For this reason, the fund's holdings in companies with European
operations experienced weaker performance due to the euro's relatively lower
value versus the U.S. dollar. It should be noted, however, that these companies
represent a relatively small portion of the portfolio and therefore did not
greatly influence fund performance.

    On a better note, a rally in energy companies--particularly refiners--and
the auto sector helped to bolster fund performance. And while the emerging
markets environment was weak early in the reporting period, the sector rebounded
in July and August as the Russian Republic bankruptcy was completed and recovery
efforts got underway. An improved political environment in Russia and a positive
shift in the psychology of the marketplace were the main contributors to this
sector's strong performance. The fund itself had moderate exposure to emerging
markets, but this sector

                                        8
<PAGE>   10

clearly added value to the portfolio. Keep in mind that there is no guarantee
that these sectors will continue to perform well or continue to be held by the
fund in the future.

Q   GIVEN THE CHALLENGING
    CONDITIONS OF THE HIGH-YIELD MARKET, WHAT WAS THE FUND'S INVESTMENT
    STRATEGY?

A   We maintained the fund's
exposure to the emerging markets sector through August. In doing so, we were
able to ride the upswing of the Russian debt market and capture strong returns.
As performance peaked in late August, we began reducing our exposure to this
sector.

    We sustained the fund's above-average weightings in casinos, commodities
(energy in particular), and telecommunications as we continued to see growth and
opportunities in these arenas.

    Our weightings in the industrial, financial, and retail sectors remained
modest, and the cash and cash equivalents portion of the portfolio was held
within its normal range of 2 to 6 percent.

    Finally, we continued to implement an investment strategy focused on
fundamental credit analysis, maintaining the fund's credit quality profile of
primarily B rated bonds. It is our belief that this segment of the high-yield
market still offers the best risk-return profile and has proved to serve the
fund well.

Q   HOW DO YOU ANTICIPATE THE HIGH-
    YIELD MARKET WILL PERFORM IN THE MONTHS AHEAD, AND HOW DO YOU EXPECT TO
    MANAGE THE FUND IN LIGHT OF THIS OUTLOOK?

A   Market indicators point to slowing
economic growth in the near term. Consumer spending has leveled off from its
pace of a year ago, and inflation is still modest. Oil prices have increased
significantly, which typically has been associated with a slowing economy. If
this proves to be the case and interest rates stabilize, we could see upward
momentum in the fixed-income marketplace and potentially stronger fund
performance.

    It is difficult to predict whether we will see additional assets flowing
into the high-yield sector in the coming months. We don't anticipate seeing any
additional large outflows or higher default-levels in the coming months. It's
important to note that, historically, Van Kampen high-yield funds have
experienced lower default rates than the market as a whole.

    We continue to find attractive opportunities in the high-yield market and
anticipate that it may continue to be a strong performer versus other
fixed-income investments. Our fundamental strategy will focus on identifying
those issuers that we believe will remain financially sound, perform well in a
range of market conditions, and add the most value to the portfolio.

GLOSSARY OF TERMS

A HELPFUL GUIDE TO SOME OF THE COMMON TERMS YOU'RE LIKELY TO SEE IN THIS REPORT
AND OTHER FINANCIAL PUBLICATIONS.

DIVERSIFICATION: A method of portfolio allocation and management aimed at
balancing investment risk and return; a balanced portfolio may combine stocks,
bonds, and cash equivalents.

EMERGING MARKETS: The financial markets of developing economies. Many Latin
American and Asian countries are considered emerging markets.

EURO: The official currency unit for the countries comprising Europe's Economic
and Monetary Union.

FEDERAL RESERVE BOARD (THE FED): The governing body of the Federal Reserve
System, which is the central bank of the United States. Its policy-making
committee, called the Federal Open Market Committee, meets at least eight times
a year to establish monetary policy and monitor the economic pulse of the United
States.

LIQUIDITY: The ease with which an investor can buy or sell a security at a
reasonable price.

YIELD: The annual rate of return on an investment, expressed as a percentage.

YIELD CURVE: The pattern that results from viewing the yields of U.S. Treasury
securities maturing in 1, 5, 10, and 30 years. When grouped together and
graphed, a pattern of increasing yield is often reflected as the time to
maturity extends. This pattern creates an upward sloping "curve." A "flat" yield
curve represents little difference between short- and long-term interest rates.

YIELD SPREAD: The additional yield investors can earn by either investing in
bonds with longer maturities or by investing in bonds with lower credit ratings.
The spread is the difference in yield between bonds with short versus long
maturities or the difference in yield between high-quality bonds and
lower-quality bonds.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen High Yield Fund (the "Fund") is organized as a series of Van Kampen
Trust, a Delaware business trust (the "Trust"), and is registered as a
diversified open-end management investment company under the Investment Company
Act of 1940, as amended. The Fund's primary investment objective is to provide a
high level of current income. The Fund invests primarily in a portfolio of
medium and lower grade domestic corporate debt securities. The Fund also may
invest up to 35% of its assets in foreign government and corporate debt
securities of comparable quality. The Fund commenced investment operations on
June 27, 1986. The Fund commenced distribution of its Class B and C shares on
May 17, 1993 and August 13, 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 Investments are stated at value using market quotations or
indications of value obtained from an independent pricing service. For those
securities where quotations or prices are not available valuations are obtained
from yield data relating to instruments or securities with similar
characteristics in accordance with procedures established in good faith by the
Board of Trustees. Short-term securities with remaining maturities of 60 days or
less are valued at amortized cost, which approximates market value.

    Fund investments include lower rated debt securities which may be more
susceptible to adverse economic conditions than other investment grade holdings.
These securities are often subordinated to the prior claims of other senior
lenders and uncertainties exist as to an issuers ability to meet principal and
interest payments. Debt securities rated below investment grade and comparable
unrated securities represented approximately 94% of the investment portfolio at
the end of the period.

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 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
maintain, in a

segregated account with its custodian, assets having an aggregate value at least
equal to the amount of the when-issued or delayed delivery purchase commitments
until payment is made.

    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 Investment Advisory Corp. (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 and
dividend income is recorded net of applicable withholding taxes on the ex-
dividend date. Bond premium is amortized and original issue discount is accreted
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.

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. Although the
Fund's fiscal year end is March 31, the Fund's tax year end is December 31.

    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 such losses against any future realized capital
gains. At December 31, 1999, the Fund had an accumulated capital loss
carryforward for tax purposes of $32,438,270, which will expire between December
31, 2001 and December 31, 2007. Net realized gains or losses may differ for
financial and tax reporting purposes primarily as a result of the difference in
the Fund's tax year end, wash sales, and reclass of consent fee income.

    At September 30, 2000, for federal income tax purposes, the cost of long-
and short-term investments is $374,855,209; the aggregate gross unrealized
appreciation is $7,914,567 and the aggregate gross unrealized depreciation is
$62,386,436,

NOTES TO

resulting in net unrealized depreciation on long- and short-term investments of
$54,471,869.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net investment income for federal income
tax purposes includes gains and losses realized on foreign currency
transactions. These gains and losses are included as net realized gains and
losses for financial reporting purposes.

    Net realized gains, if any, are distributed annually. Distributions from net
realized gains for book purposes may include short-term capital gains, which are
included as ordinary income for tax purposes.

    Due to inherent differences in the recognition of distributions from income
under generally accepted accounting principles and federal income tax purposes,
the amount of distributable net investment income may differ between book and
federal income tax purposes for a particular period. These differences are
temporary in nature, but may result in distributions in excess of net investment
income for certain periods.

    For tax purposes, the determination of a return of capital distribution is
made at the end of the Fund's taxable year (December 31).

F. CURRENCY TRANSLATION Assets and liabilities denominated in foreign currencies
and commitments under forward currency contracts are translated into U.S.
dollars at the mean of the quoted bid and ask 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.
Income and expenses are translated at rates prevailing when accrued.

G. EXPENSE REDUCTIONS During the six months ended September 30, 2000, the Fund's
custody fee was reduced by $23,790 as a result of credits earned on overnight
cash balances.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

</TABLE>

    For the six months ended September 30, 2000, the Adviser waived
approximately $175,500 of its advisory fee. This waiver is voluntary and may be
discontinued at any time.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $6,400, representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $27,400, representing Van Kampen Funds Inc.'s or its affiliates'
(collectively "Van Kampen") cost of providing accounting and legal services to
the Fund.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the six months ended September
30, 2000, the Fund recognized expenses of approximately $173,500. Transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees and are based on competitive market benchmarks.

    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 to a
later date. Benefits under the retirement plan are payable 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.

4. INVESTMENT TRANSACTIONS

During the period ended September 30, 2000, the cost of purchases and proceeds
from sales of investments, excluding short-term investments, were $153,004,770
and $157,271,630, 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 and to manage the portfolio's effective yield, foreign currency
exposure, maturity and duration, 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 appreciation/depreciation.
Upon disposition, a realized gain or loss is recognized accordingly, except when
exercising a call option contract or taking delivery of a security underlying a
futures or forward contract. In these instances, the recognition of gain or loss
is postponed until the disposal of the security underlying the option, futures
or forward contract. Risks may arise as a result of the potential inability of
the counterparties to meet the terms of their contracts.

NOTES TO
FINANCIAL STATEMENTS

September 30, 2000 (Unaudited)

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

A. OPTION CONTRACTS An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration. As of September 30,
2000, there were no option contracts outstanding.

B. 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 and typically closes
the contract prior to the delivery date. These contracts are generally used to
manage the portfolio's effective maturity and duration.

    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, cash or liquid securities with a value equal to its
obligation under the futures contracts. 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). As of September 30, 2000,
there were no futures contracts outstanding.

C. FORWARD CURRENCY CONTRACTS These instruments are commitments to purchase or
sell a foreign currency at a future date at a negotiated forward rate. The gain
or loss arising from the difference between the original value of the contract
and the closing value of such contract is included as a component of realized
gain/loss on forwards. As of September 30, 2000, there were no forward currency
contracts outstanding.

D. SWAP TRANSACTIONS These securities represent an agreement between two parties
to exchange a series of cash flows based upon various indices at specified
intervals. There were no open swap transactions at September 30, 2000.

6. BANK LOAN PARTICIPATIONS

The Fund invests in participation interests of loans to foreign entities. When
the Fund purchases a participation of a foreign loan interest, the Fund
typically enters into a contractual agreement with the lender or other third
party selling the participation, but not with the borrower directly. As such,
the Fund assumes credit risk for the borrower, selling participant or other
persons positioned between the Fund and the borrower.

7. DISTRIBUTION AND SERVICE PLANS

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940, as amended, and a service plan
(collectively the "Plans"). The Plans govern payments for the distribution of
the Fund's shares, ongoing shareholder services and maintenance of shareholder
accounts.

    Annual fees under the Plans of up to .25% for Class A net assets and 1.00%
each for Class B and Class C net assets are accrued daily. Included in these
fees for the six months ended September 30, 2000, are payments retained by Van
Kampen of approximately $448,800.

8. BORROWINGS

In accordance with its investment policies, the Fund may borrow from banks for
temporary purposes and is subject to certain other customary restrictions.
Effective November 30, 1999, the Fund, in conjunction with certain other funds
of Van Kampen, entered in to a $650,000,000 committed line of credit facility
with a group of banks which expires on November 28, 2000, but is renewable with
the consent of the participating banks. Each fund is permitted to utilize the
facility in accordance with the restrictions of its prospectus. In the event the
demand for the credit facility meets or exceeds $650 million on a complex-wide
basis, each fund will be limited to its pro-rata percentage based on the net
assets of each participating fund. Interest on borrowings is charged under the
agreement at a rate of 0.50% above the federal funds rate per annum. An annual
commitment fee of 0.09% per annum is charged on the unused portion of the credit
facility, which each fund incurs based on its pro-rata percentage of quarterly
net assets. The Fund has not borrowed against the credit facility during the
period.

 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,

The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
                  nearly four generations of investment-management experience,
                  we've been around long enough to understand that by investing
with Van Kampen you're entrusting us with much more than your money. Your
investments may help make it possible to afford your next house, keep up with
rising college costs, or enjoy a comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

(1) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge (4.75% for Class A shares) or
    contingent deferred sales charge ("CDSC") for Class B and C shares. On
    purchases of Class A shares of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. Returns for
    Class B shares are calculated without the effect of the maximum 4% CDSC,
    charged on certain redemptions made within one year of purchase and
    declining thereafter to 0% after the sixth year. Returns for Class C shares
    are calculated without the effect of the maximum 1% CDSC, charged on certain
    redemptions made within one year of purchase. If the sales charges were
    included, total returns would be lower. These returns do include Rule 12b-1
    fees of up to .25% for Class A Shares and 1% for Class B and Class C Shares.

(2) Standardized total return. Assumes reinvestment of all distributions for the
    period and includes payment of the maximum sales charge (4.75% for Class A
    shares) or contingent deferred sales charge ("CDSC") for Class B and C
    shares and Rule 12b-1 fee. On purchases of Class A shares of $1 million or
    more, a CDSC of 1% may be imposed on certain redemptions made within one
    year of purchase. Returns for Class B shares are calculated with the effect
    of the maximum 4% CDSC, charged on certain redemptions made within one year
    of purchase and declining thereafter to 0% after the sixth year. Returns for
    Class C shares are calculated with the effect of the maximum 1% CDSC,
    charged on certain redemptions made within one year of purchase. The Rule
    12b-1 fee for Class A Shares is up to .25% and for Class B and Class C
    Shares is 1%.

(3) The total return reflects the conversion of Class B shares into Class A
    shares six years after the end of the calendar month in which the shares
    were purchased.

(4) Distribution rate represents the monthly annualized distributions of the
    Fund at the end of the period and not the earnings of the Fund.

(5) SEC Yield is a standardized calculation prescribed by the Securities and
    Exchange Commission for determining the amount of net income a portfolio
    should theoretically generate for the 30-day period ending September 30,
    2000. Had certain expenses of the Fund not been assumed by Van Kampen, total
    returns would have been lower and the SEC Yield would have been 8.24%, 7.89%
    and 7.89% for Classes A, B and C, respectively.

    See the Comparative Performance section of the current prospectus. Past
    performance is no guarantee of future results. Investment return and net
    asset value will fluctuate with market conditions. Fund shares, when
    redeemed, may be worth more or less than their original cost.

    A substantial portion of the Fund's assets may be invested in lower-grade
    income securities, including issues of emerging market countries and
    securities rated in the lowest categories, commonly referred to as junk
    bonds. The Fund's investments in emerging market securities have the
    potential for risks not associated with investments in the United States.
    The Fund's investments in junk bonds have the potential for risks not
    generally associated with higher rated fixed income securities.

    The Fund may react to changes in interest rate cycles, business or economic
    conditions, rates of inflation, or other market conditions. Global
    investing, investing in lower rated securities, and investing in a limited
    number of sectors each hold the potential for risks not associated with many
    other types of fixed-income investments.

    Market forecasts provided in this report may not necessarily come to pass.

    As a result of recent market activity, current performance may vary from the
    figures shown.

Q&A WITH YOUR PORTFOLIO MANAGERS

WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF THE VAN
KAMPEN STRATEGIC INCOME FUND ABOUT THE KEY EVENTS AND
ECONOMIC FORCES THAT SHAPED THE MARKETS AND INFLUENCED THE
FUND'S RETURN DURING THE PAST SIX MONTHS. THE FUND IS
CO-MANAGED BY TOM SLEFINGER, ROBERT J. HICKEY, AND TED
MUNDY. THE FOLLOWING DISCUSSION REFLECTS THEIR VIEWS ON THE FUND'S PERFORMANCE.
PLEASE NOTE: AFTER CONSIDERATION OF A NUMBER OF FACTORS, THE BOARD
OF TRUSTEES OF THE STRATEGIC INCOME FUND DETERMINED IT WOULD BE IN
THE BEST INTEREST OF THE FUND'S SHAREHOLDERS TO TERMINATE AND LIQUIDATE THE
FUND. THE PLAN OF LIQUIDATION FOR THE FUND WAS APPROVED BY THE BOARD ON
SEPTEMBER 12, 2000, AND WILL BE PRESENTED TO FUND SHAREHOLDERS FOR APPROVAL.

Q   DESCRIBE THE MARKET CONDITIONS
    OF THE LAST SIX MONTHS AND HOW THE FUND PERFORMED IN THIS ENVIRONMENT.

A   Economic growth and consumer
spending were accelerating early in the reporting period. We saw continued
efforts by the Federal Reserve Board to slow the economy and fend off
inflationary risks through its policy of increasing interest rates. While this
aggressive policy pushed short-term rates up, the Treasury announced a plan to
buy back long-term Treasury bonds, which created a perceived shortage of long
bonds. The result was a highly unusual inverted yield curve--where yields on
long-term securities were actually lower than their short-term counterparts--and
a dramatic widening of credit spreads.

    The curve inversion peaked in May as it appeared the Fed was done raising
rates. Subsequently, a series of economic reports indicated that economic growth
was moderating, market sentiment became more positive, and interest rates began
to stabilize. In turn, credit spreads
began to narrow again, enabling
mortgage-backed securities, high-yield
bonds, and corporate bonds to outperform Treasuries.

    Turning to the markets abroad, the emerging markets sector was a very strong
performer for much of the last six months. Russian debt securities in particular
experienced a significant rebound as the Russian Republic bankruptcy was
completed and recovery efforts got underway.

    For the six months ended September 30, 2000, the fund posted a total return
of 1.15% percent (Class A shares at net asset value; if the maximum sales charge
of 4.75 percent

                                        7

were included, the return would be lower). Of course, past performance is no
guarantee of future results. As a result of recent market activity, current
performance may vary from the figures shown. By comparison, the Lehman Brothers
Aggregate Bond Index, an unmanaged, broad-based index, generated a total return
of 4.81 percent for the same period. Similarly, a composite index of 20 percent
each of the Salomon Brothers Indexes for Mortgages, High Yield Market,
Corporate, Non-U.S. Dollar World Government, and Brady Bonds produced a total
return of 2.30 percent during the period. Keep in mind that these indexes do not
reflect any commissions or fees that would be paid by an investor purchasing the
securities they represent. Such costs would lower the performance of the
indexes. It is not possible to invest directly in an index. Please refer to the
chart and footnotes on page 4 for additional fund performance results.

Q   CAN YOU EXPLAIN HOW THE FUND
    WAS POSITIONED AT THE END OF THE PERIOD?

A   As of September 30, 2000,
21 percent of the long-term portfolio of investments was allocated to the
foreign investment-grade sector, compared to 16.2 percent in the foreign
lower-grade sector, which consists primarily of emerging market securities. Of
the remaining sectors, 28.8 percent of the fund's long-term investments were in
domestic lower-grade securities, 8.8 percent were in domestic investment-grade
securities, and 18.9 percent were in the U.S. government and mortgage-backed
securities sector. For additional portfolio highlights, please refer to page 6.

Q   WHAT WERE THE EFFECTS OF THE
    MARKET CONDITIONS ON THE FUND, AND HOW DID YOU MANAGE THE FUND IN LIGHT OF
    THESE CONDITIONS?

A   The most notable interest-rate
declines in the inverted yield curve environment were within the
intermediate-term sector of the curve (five- to seven-year bonds). The fund had
a higher weighting in this maturity range than the benchmark, enabling us to
capture some positive performance here.

    In addition, the fund had greater allocation in the higher-quality, more
liquid securities within the domestic high-yield sector of the bond market. This
component experienced better performance than the lower-quality component of the
high-yield market, due primarily to the fact that credit and default concerns
had a lesser impact on the higher-quality securities. The fund's emphasis on
this portion of the high-yield market added significant relative value to the
portfolio.

    The emerging markets sector has been the best-performing fixed-income asset
class in 2000. As mentioned earlier, the substantial rebound of Russian debt was
the key reason for this upswing. We've seen an improved political environment
there and a favorable shift in the psychology of the marketplace. As a result,
the fund benefited from its above-average weighting in this sector.

    The world's developed markets were more erratic. Early in the reporting
period, the fund experienced positive performance due to its above-average
weighting in investment-grade foreign securities as the euro rallied against the
U.S. dollar. By July, however, this trend had reversed, and the dollar's value
climbed versus the European and dollar-bloc currencies (i.e., Canadian,
Australian, and New Zealand dollars), as well as the yen. Our strategy of
carrying a significant exposure to the investment-grade foreign sector had a
negative impact on the fund during the last few months of the reporting period.

GLOSSARY OF TERMS

A HELPFUL GUIDE TO SOME OF THE COMMON TERMS YOU'RE LIKELY TO SEE IN THIS REPORT
AND OTHER FINANCIAL PUBLICATIONS.

BRADY BOND: U.S. dollar-denominated bonds issued by developing markets,
particularly in Latin America.

CREDIT SPREAD: Also called quality spread, the difference in yield between
higher-quality issues (such as Treasury securities) and lower-quality issues.
Normally, lower-quality issues provide higher yields to compensate investors for
the additional credit risk.

EMERGING MARKETS: The financial markets of developing economies. Many Latin
American and Asian countries are considered emerging markets.

EURO: The official currency unit for the countries comprising Europe's Economic
and Monetary Union.

FEDERAL RESERVE BOARD (THE FED): The governing body of the Federal Reserve
System, which is the central bank of the United States. Its policy-making
committee, called the Federal Open Market Committee, meets at least eight times
a year to establish monetary policy and monitor the economic pulse of the United
States.

NET ASSET VALUE (NAV): The value of a mutual fund share, calculated by deducting
a fund's liabilities from the total assets in its portfolio and dividing this
amount by the number of shares outstanding. The NAV does not include any initial
or contingent deferred sales charge.

YIELD CURVE: The pattern that results from viewing the yields of U.S. Treasury
securities maturing in 1, 5, 10, and 30 years. When grouped together and
graphed, a pattern of increasing yield is often reflected as the time to
maturity extends. This pattern creates an upward sloping "curve." A "flat" yield
curve represents little difference between short- and long-term interest rates.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Strategic Income Fund (the "Fund") is organized as a series of Van
Kampen Trust (the "Trust"), a Delaware business trust, and is registered as a
non-diversified open-end management investment company under the Investment
Company Act of 1940, as amended. The Fund's primary investment objective is to
seek to provide shareholders with high current income, while its secondary
investment objective is to seek capital appreciation. The Fund will allocate its
investments among the following market sectors: U.S. government securities,
domestic investment grade income securities, domestic lower grade income
securities, foreign investment grade income securities and foreign lower grade
income securities. The Fund borrows money for investment purposes which will
create the opportunity for enhanced return, but also should be considered a
speculative technique and may increase the Fund's volatility. The Fund commenced
investment operations on December 31, 1993, with three classes of common shares:
Class A, Class B and Class C shares.

    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 these estimates.

A. SECURITY VALUATION Investments are stated at value using market quotations,
prices provided by market makers or, if such valuations are not available,
estimates obtained from yield data relating to instruments or securities with
similar characteristics in accordance with procedures established in good faith
by the Board of Trustees. Foreign investments are stated at value using the last
available bid price or yield equivalents obtained from dealers in the
over-the-counter (OTC) or interbank market. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost which approximates
market value. Cash includes cash deposited in demand deposits at banks.

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 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
maintain, in a segregated account with its custodian, assets having an aggregate
value at least

                                       25
<PAGE>   65

NOTES TO

September 30, 2000 (Unaudited)

equal to the amount of the when-issued or delayed delivery purchase commitments
until payment is made. At September 30, 2000, there were no when issued or
delayed delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis and
dividend income is recorded on the ex-dividend date. Original issue discount is
accreted 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.

D. CURRENCY TRANSLATION Assets and liabilities denominated in foreign currencies
and commitments under forward currency contracts are translated into U.S.
dollars at the mean of the quoted bid and ask 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.
Income and expenses are translated at rates prevailing when accrued.

E. 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 such losses against any future realized capital
gains. At December 31, 1999, the Fund had an accumulated capital loss
carryforward for tax purposes of $14,020,988 which will expire between December
31, 2002 and December 31, 2007. Net realized gains or losses may differ for
financial and tax reporting purposes primarily as a result of wash sales.

    At September 30, 2000, for federal income tax purposes, the cost of long-
and short-term investments is $84,204,549; the aggregate gross unrealized
appreciation is $1,484,078 and the aggregate gross unrealized depreciation is
$10,328,702, resulting in net unrealized depreciation on long- and short-term
investments of $8,844,624.

F. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays dividends
monthly from net investment income. Net investment income for federal income tax
purposes includes gains and losses realized on transactions in foreign
currencies and options and futures on foreign currencies. These realized gains
and

losses are included as net realized gains or losses for financial reporting
purposes. Net realized gains, if any, are distributed annually.

G. EXPENSE REDUCTIONS During the six months ended September 30, 2000, the Fund's
custody fee was reduced by $5,800 as a result of credits earned on overnight
cash balances.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen
Investment Advisory Corp. ("the Adviser") will provide investment advice and
facilities to the Fund for an annual fee payable monthly as follows:

First $500 million..........................................   .75 of 1%
Next $500 million...........................................   .70 of 1%
Over $1 billion.............................................   .65 of 1%
</TABLE>

    For the six months ended September 30, 2000, the Adviser voluntarily waived
approximately $78,400 of its investment advisory fees. This waiver is voluntary
and can be discontinued at any time.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $1,100 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $18,500 representing Van Kampen's cost of providing accounting,
cash management and legal services to the Fund.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the six months ended September
30, 2000, the Fund recognized expenses of approximately $41,000. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

    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 to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are

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, manage the portfolio's effective yield, foreign currency exposure,
maturity and duration 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 appreciation/depreciation. Upon
disposition, a realized gain or loss is recognized accordingly, except when
exercising a call option contract or taking delivery of a security underlying a
futures or forward contract. In these instances, the recognition of gain or loss
is postponed until the disposal of the security underlying the option, futures
or forward contract. Risks may arise as a result of the potential inability of
the counterparties to meet the terms of their contracts.

NOTES TO

September 30, 2000 (Unaudited)

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

A. OPTION CONTRACTS An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.

    There were no transactions in option contracts for the six months ended
September 30, 2000.

B. 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 and typically closes
the contract prior to the delivery date. These contracts are generally used to
manage the portfolio's effective maturity and duration.

    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, cash or liquid securities with a value equal to its
obligation under the futures contracts. 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 cost of securities
acquired through delivery under a contract is adjusted by the unrealized gain or
loss on the contract.

    There were no transactions in futures contracts for the six months ended
September 30, 2000.

C. FORWARD CURRENCY CONTRACTS These instruments are commitments to purchase or
sell a foreign currency at a future date at a negotiated forward rate. The gain
or loss arising from the difference between the original value of the contract
and the closing value of such contract is included as a component of realized
gain/loss on forwards.

    At September 30, 2000 there were no open forward currency contracts.

D. CLOSED BUT UNSETTLED FORWARD COMMITMENTS In certain situations, the Fund has
entered into offsetting transactions for outstanding forward commitments prior
to settlement of the obligation. In doing so, the Fund realizes a gain or loss
on the transactions at the time the forward commitment is closed. Risk may
result due to the potential inability of counterparties to meet the terms of
their contracts.

E. INVERSE FLOATING SECURITY These instruments have a coupon which is inversely
indexed to a short-term floating interest rate multiplied by a specified factor.
As

NOTES TO

the floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. The price of these securities may be more
volatile than the price of a comparable fixed rate security. These instruments
are typically used by the Fund to enhance the yield of the portfolio.

F. INTEREST ONLY/PRINCIPAL ONLY SECURITIES A Mortgage-Backed Security or U.S.
Treasury Obligation may be stripped to create an Interest Only (IO) security and
a Principal Only (PO) security. An IO represents ownership in the cash flows of
the interest payments or coupon payments made. The cash flow from an IO
instrument decreases as the borrower repays the principal balance. Conversely, a
PO represents ownership in the cash flows of the principal payments made. A PO
created from a U.S. Treasury Obligation becomes a zero coupon bond. The cash
flow on a PO instrument increases as the borrowers repay the principal balance.
These instruments are typically used to manage interest rate exposure in the
fund's portfolio.

6. MORTGAGE-BACKED SECURITIES

A Mortgage-Backed Security (MBS) is a pass-through security created by pooling
mortgages and selling participations in the principal and interest payments
received from borrowers. Most of these securities are guaranteed by federally
sponsored agencies such as Federal National Mortgage Association (FNMA).

    A REMIC (Real Estate Mortgage Investment Conduit) is a bond which is
collateralized by a pool of MBS's. These MBS pools are divided into classes or
tranches with each class having its own characteristics.

7. ASSET-BACKED SECURITIES

An Asset-Backed Security (ABS) is a security collateralized by assets such as
installment loans, leases, mortgage loans, receivables or other kinds of assets
that are issued independently of the originator.

8. BANK LOAN PARTICIPATIONS

The Fund invests in participation interests of loans to foreign entities. When
the Fund purchases a participation of a foreign loan interest, the Fund
typically enters into a contractual agreement with the lender or other third
party selling the participation, but not with the borrower directly. As such,
the Fund assumes credit risk for the borrower, selling participant or other
persons positioned between the Fund and the borrower.

9. DISTRIBUTION AND SERVICE PLANS

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940, as amended, and a service plan
(collectively the "Plans"). The Plans govern payments for the distribution of
the Fund's shares, ongoing shareholder services and maintenance of shareholder
accounts.

    Annual fees under the Plans of up to .25% of Class A net assets and 1.00%
each of Class B and Class C net assets are accrued daily. Included in these fees
for the six months ended September 30, 2000, are payments retained by Van Kampen
of approximately $171,400.

10. BORROWINGS

In accordance with its investment policies, the Fund may borrow money from banks
or enter into reverse repurchase agreements or dollar rolls for investment
purposes in an amount up to 33.3% of its total assets.

    During the period, the Fund entered into a $45,000,000 revolving credit
agreement which expired on May 31, 2000. Interest was charged under the
agreement at a rate of .425% above the federal funds rate. An annual facility
fee of .075% was charged on the maximum facility of this line of credit.

    During the period, the Fund entered into reverse repurchase agreements with
Warburg Dillion Read LLC, under which the Fund would sell securities and agreed
to repurchase them at a mutually agreed upon date and price.

    The average daily balance of bank borrowings and reverse repurchase
agreements for the six months ended September 30, 2000, was approximately
$6,703,000 with an average interest rate of 6.80%.

business relationship by KPMG with an affiliate of the Fund's investment
adviser.
