SUPPLEMENTED DATED MARCH 7, 2005
                                     TO THE
                      STATEMENT OF ADDITIONAL INFORMATION
                            DATED DECEMBER 30, 2004
 
                          VAN KAMPEN HIGH YIELD FUND,
                 AS PREVIOUSLY SUPPLEMENTED ON FEBRUARY 2, 2005
 
     The Statement of Additional Information is hereby supplemented as follows:
 
     The following is added after the first paragraph in the section entitled
"INVESTMENT OBJECTIVE, PRINCIPAL INVESTMENT STRATEGIES AND RISKS -- SECURITIES
OF FOREIGN ISSUERS:"
 
          FOREIGN CURRENCY EXCHANGE RISKS. To the extent the Fund invests in
     securities denominated or quoted in currencies other than the U.S. dollar,
     the Fund will be affected by changes in foreign currency exchange rates
     (and exchange control regulations) which affect the value of investments in
     the Fund and the income and appreciation or depreciation of the
     investments. Changes in foreign currency exchange ratios relative to the
     U.S. dollar will affect the U.S. dollar value of the Fund's assets
     denominated in that currency and the Fund's yield on such assets. In
     addition, the Fund will incur costs in connection with conversions between
     various currencies.
 
          The Fund's foreign currency exchange transactions may be conducted on
     a spot basis (that is, cash basis) at the spot rate for purchasing or
     selling currency prevailing in the foreign currency exchange market. The
     Fund also may enter into contracts with banks, brokers or dealers to
     purchase or sell securities or foreign currencies at a future date
     ("forward contracts"). A foreign currency forward contract is a negotiated
     agreement between the contracting parties to exchange a specified amount of
     currency at a specified future time at a specified rate. The rate can be
     higher or lower than the spot rate between the currencies that are the
     subject of the contract.
 
          The Fund may attempt to protect against adverse changes in the value
     of the U.S. dollar in relation to a foreign currency by entering into a
     forward contract for the purchase or sale of the amount of foreign currency
     invested or to be invested or by buying or selling a foreign currency
     option or futures contract for such amount. Such strategies may be employed
     before the Fund purchases a foreign security traded in the currency which
     the Fund anticipates acquiring or between the date the foreign security is
     purchased or sold and the date on which payment therefor is made or
     received. Seeking to protect against a change in the value of a foreign
     currency in the foregoing manner does not eliminate Fluctuations in the
     prices of portfolio securities or prevent losses if the prices of such
     securities decline. Furthermore, such transactions reduce or preclude the
     opportunity for gain if the value of the currency should move in the
     direction opposite to the position taken. Unanticipated changes in currency
     prices may result in poorer overall performance for the Fund than if it had
     not entered into such contracts. The Fund is not required to enter into
     such transactions with regard to its foreign currency-denominated
     securities. It also should be realized that this method of protecting the
     value of portfolio securities against a decline in the value of a currency
     does not eliminate fluctuations in the underlying prices of the securities.
     It simply establishes a rate of exchange which one can achieve at some
     future point in time. In addition, although such contracts tend to minimize
     the risk of loss due to a decline in the value of the hedged currency, at
     the same time, they tend to limit any potential gain which might result
     should the value of such currency increase.
 
          The Fund may cross-hedge currencies by entering into a transaction to
     purchase or sell one or more currencies that are expected to decline in
     value relative to other currencies to which a portfolio has or expects to
     have portfolio exposure. The Fund may also engage in proxy hedging, which
     is defined as entering into positions in one currency to hedge investments
     denominated in another currency, where two currencies are economically
     linked. The Fund's entry into forward contracts, as well as any use of
     proxy or cross hedging techniques, will generally require the Fund to
     segregate cash and/or liquid securities at least equal to the Fund's
     obligations throughout the duration of the contract. The Fund may combine
     forward contracts with investments in securities denominated in other
     currencies to achieve desired security and currency exposures. Such
     combinations are generally referred to as synthetic securities. For

 
     example, in lieu of purchasing a foreign bond, the Fund may purchase a U.S.
     dollar-denominated security and at the same time enter into a forward
     contract to exchange U.S. dollars for the contract's underlying currency at
     a future date. By matching the amount of U.S. dollars to be exchanged with
     the anticipated value of the U.S. dollar-denominated security, the Fund may
     be able to lock in the foreign currency value of the security and adopt a
     synthetic position reflecting the credit quality of the U.S. dollar-
     denominated security.
 
          To the extent required by the rules and regulations of the SEC, the
     Fund will segregate cash and/or liquid securities in an amount at least
     equal to the value of the Fund's total assets committed to the consummation
     of forward foreign currency exchange contracts. If the value of the
     segregated assets declines, additional cash and/or liquid securities will
     be segregated on a daily basis so that the value of the segregated assets
     will be at least equal to the amount of the Fund's commitments with respect
     to such contracts.
