Intermediary defined sales charge waiver policies

The availability of certain sales charge waivers and discounts may depend on whether you purchase and sell your shares directly from the fund or through a financial intermediary. Specific intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or contingent deferred (back-end) sales load (CDSC) waivers. In all instances, it is your responsibility to notify the fund or your financial intermediary at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, you will have to purchase fund shares directly from the fund or through another intermediary to receive these waivers or discounts. The following provides additional information about transactions through the following intermediaries. References to Class C shares also refer generally to Class C2 shares (if available).
