In all instances, it is your responsibility to notify your financial intermediary or MFSC at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or reductions. For waivers and reductions not available through a particular financial intermediary, shareholders will have to purchase fund shares through another financial intermediary or directly from the fund to receive these waivers or reductions. You should contact your financial intermediary or MFSC if you have questions on the waivers and reductions that apply to your account and/or transaction type, including whether your account is maintained at an omnibus level with the fund by your financial intermediary.
