Effective immediately, the prospectuses for Class A shares of the Funds are
hereby supplemented as described below.

For all Funds, the section entitled "SALES CHARGES; Class A shares" is revised
 and replaced in its entirety with the following:

o        Class A shares Your purchases of Class A shares are made at the public
         offering price for these shares. This price includes a sales charge
         that is based on the amount of your initial investment when you open
         your account. The sales charge you pay on an additional investment is
         based on the total amount of your purchase and the current value of
         your account. Shares you purchase with reinvested dividends or other
         distributions are not subject to a sales charge. Purchases by insurance
         company separate accounts for the benefit of group retirement plans may
         buy Class A shares without paying a front-end sales charge. A portion
         of the sales charge is paid as a commission to your financial advisor
         on the sale of Class A shares. The amount of the sales charge differs
         depending on the amount you invest as shown in the table below.
