                  CIK No.: 0000787623

Dear Commissioners:

         On behalf of IDEX Mutual Funds (the "Fund"), we are filing a
certification pursuant to paragraph (j) of Rule 497 under the Securities Act of
1933. In this regard, we certify that the form of Prospectus for the Fund dated
March 1, 2001 otherwise required to be filed under paragraph (c) of Rule 497
would not have differed from the form of Prospectus contained in the Form N1-A
registration statement for the Fund (the "Registration Statement"). The
Registration Statement was filed electronically with the Securities and Exchange
Commission on March 1, 2001 via EDGAR.

                                                     Sincerely,


                                                     /s/ JOHN K. CARTER
                                                     ---------------------------
                                                     John K. Carter, Esq.
                                                     Vice President, Secretary
                                                     & Counsel
