Effective on or about September 3, 2013, the “Class A Shares” sub-section of “Part II: APPENDIX II-D - FINANCIAL SERVICES FIRMS’ COMPENSATION” of Part II of the funds’ Statement of Additional Information is amended as follows:

CLASS A SHARES: The fund receives the entire net asset value of all its Class A shares sold. DIDI, as principal underwriter, retains the sales charge on sales of Class A shares from which it allows discounts from the applicable public offering price to investment dealers, which discounts are uniform for all dealers in the United States and its territories. The normal discount is set forth in the sales charge tables set forth in APPENDIX II-F. Upon notice to all dealers, DIDI may re-allow to dealers up to the full applicable Class A sales charge during periods and for transactions specified in such notice and such re-allowances may be based upon attainment of minimum sales levels. During periods when 90% or more of the sales charge is re-allowed, such dealers may be deemed to be underwriters as that term is defined in the 1933 Act.

DIDI may at its discretion compensate investment dealers or other financial services firms in connection with the sale of Class A shares of a fund in accordance with the Large Order NAV Purchase Privilege and one of the compensation schedules up to the following amounts:
