FUND HIGHLIGHTS
The "FUND HIGHLIGHTS--What Are the Key Facts Regarding the Funds? --WHAT ARE THE
OPTIONS FOR INVESTMENT IN THE FUNDS?" section in the Prospectus is hereby
deleted in its entirety and replaced with the following:
Q: WHAT ARE THE OPTIONS FOR INVESTMENT IN THE FUNDS?
A: Each Fund, other than the NetNet Fund, offers five different investment
options, or classes: Class A, B, C, K and Y. The NetNet Fund offers four
different investment options, or classes: Class A, B, C and Y. Class K and Y
shares, which are only offered to institutional and other qualified investors,
are offered in other prospectuses.

- -------------------------------------
* An annual fee for distributing shares and servicing shareholder accounts based
on the Fund's average daily net assets.
** A one-time fee charged at the time of purchase of shares. The fee declines
based on the amount you invest.
*** A contingent deferred sales charge ("CDSC") is a one-time fee charged at the
time of redemption. The fee declines based on the length of time you hold the
shares.
+ A CDSC of 1% is imposed on certain redemptions of Class A Shares if redeemed
within one year of purchase.
(i) If you invest over $250,000, you must buy Class A or Class C Shares.
(ii) Class B Shares convert automatically to Class A Shares after six years.
Due to the level of Rule 12b-1 fees and the CDSC on Class B Shares versus Class
A or Class C Shares, both (i) and (ii) are to your economic benefit.
FUND OPERATING EXPENSES
The "FUND OPERATING EXPENSES" section in the Prospectus with respect to the
Munder NetNet Fund is hereby deleted and replaced with the following:
