Pursuant to Rule 497(j) under the Securities Act of 1933, as amended, this letter serves as certification that the forms of Prospectuses and Statement of Additional Information that would have been filed under paragraph (c) of Rule 497 would not have differed from those filed in Post-Effective Amendment No. 83 (the “Amendment”) to the Registrant’s Registration Statement on Form N-1A.  The Amendment was filed with the U.S. Securities and Exchange Commission electronically on November 28, 2012.

If you have any questions or comments regarding this filing, please call me at (215) 564-8099.

Very truly yours,
