The paragraph captioned “Automatic conversion of Class C shares” in the “Purchase, exchange and sale of shares” section of the prospectus is amended in its entirety to read as follows:

Automatic conversion of Class C and Class 529-C shares Class C shares automatically convert to Class F-1 shares and Class 529-C shares automatically convert to Class 529-A shares, in each case in the month of the 10-year anniversary of the purchase date. The Internal Revenue Service currently takes the position that such automatic conversions are not taxable. Should its position change, the automatic conversion feature may be suspended. If this were to happen, you would have the option of converting your Class C shares to Class F-1 shares or your Class 529-C shares to Class 529-A shares at the anniversary date described above. This exchange would be based on the relative net asset values of the two classes in question, without the imposition of a sales charge or fee, but you might face certain tax consequences as a result.

Keep this supplement with your prospectus.
