This filing contains the Prospectus(es) and Statement(s) of Additional Information for the fund(s) referenced above.

Pursuant to Rule 472 under the 33 Act, copies indicating modifications and editorial changes made since the filing of the last applicable Registration Statement for each fund’s Prospectus(es) and SAI(s) are filed herein.

Please note that certain charts and tabular information will be included in the applicable Prospectus(es) and Statement(s) of Additional Information in a subsequent amendment to the trust’s Registration Statement.
