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 November 1,
1999, 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 November 1, 1999 via EDGAR.
Sincerely,
/s/ JOHN C. CARTER
