Dear Mr. Cowan:

Enclosed for filing on behalf of the Registrant is Post-Effective Amendment No. 264 to the registration statement of the Registrant on Form N-1A (the Amendment) under Rule 485(a)(1) of the Securities Act of 1933. The purpose of the Amendment is to update the Fund’s prospectus and Statement of Additional Information (SAI) to reflect changes to its principal investment strategies and principal risks.

Sincerely,
