VAN KAMPEN ENTERPRISE FUND
SUPPLEMENT DATED JANUARY 8, 2001 TO THE
STATEMENT OF ADDITIONAL INFORMATION DATED SEPTEMBER 25, 2000,
SUPERSEDING ALL PRIOR SUPPLEMENTS
The Statement of Additional Information is hereby supplemented as follows:
(1) The first and second paragraphs in the section entitled "INITIAL AND
VARIATION MARGIN" under the "OPTIONS, FUTURES AND RELATED OPTIONS -- FUTURES
CONTRACTS" section is hereby deleted in its entirety and replaced with the
following:
INITIAL AND VARIATION MARGIN. In contrast to the purchase or sale of a
security, no price is paid or received upon the purchase or sale of a futures
contract. Initially, the Fund is required to deposit an amount of cash or liquid
securities equal to a percentage (which will normally range between 2% and 10%)
of the contract amount with either a futures commission merchant pursuant to
rules and regulations promulgated under the 1940 Act or with its custodian in an
account in the broker's name. This amount is known as initial margin. The nature
of initial margin in futures transactions is different from that of margin in
securities transactions in that futures contract margin does not involve the
borrowing of funds by the customer to finance the transaction. Rather, the
initial margin is in the nature of a performance bond or good faith deposit on
the contract, which is returned to the Fund upon termination of the futures
contract and satisfaction of its contractual obligations. Subsequent payments to
and from the broker, called variation margin, are made on a daily basis as the
price of the underlying securities or index fluctuates, making the long and
short positions in the futures contract more or less valuable, a process known
as marking to market.
For example, when the Fund purchases a futures contract and the price of
the underlying security or index rises, that position increases in value, and
the Fund receives a variation margin payment equal to that increase in value.
Conversely, where the Fund purchases a futures contract and the value of the
underlying security or index declines, the position is less valuable, and the
Fund is required to make a variation margin payment.
(2) The section entitled "TRUSTEES AND OFFICERS -- TRUSTEES" is hereby
amended by deleting all information pertaining to Fernando Sisto, effective
December 31, 2000.
(3) The section entitled "OTHER INFORMATION -- CUSTODY OF ASSETS" is hereby
deleted in its entirety and replaced with the following:
Except for segregated assets held by a futures commission merchant pursuant
to rules and regulations promulgated under the 1940 Act, all securities owned by
the Fund and all cash, including proceeds from the sale of shares of the Fund
and of securities in the Fund's investment portfolio, are held by State Street
Bank and Trust Company, 225 Franklin Street, Boston, Massachusetts 02110, as
custodian. The custodian also provides accounting services to the Fund.
