Re: Aon Funds (the "Trust")
File Nos. 811-6422 and 33-43133
Ladies and Gentlemen:
We refer to Amendment No. 12 under the Investment Company Act of
1940, as amended, and Post-Effective Amendment No. 11 under the Securities Act
of 1933, as amended, to the Registration Statement on Form N-1A of the Company
(the "Amendment"), which was filed and became effective on February 27, 1998.
The Amendment is the most recent amendment filed by the Company.
The Company has authorized us to convey to the Commission its
certification that:
(1) the form of prospectus and Statement of Additional Information
that would have been filed under Rule 497(c) would not have differed from that
contained in the Amendment, and
(2) the text of the Amendment has been filed electronically.
Accordingly, as permitted by Rule 497(j), the form of prospectus and
Statement of Additional Information that would have been filed by the Company
under Rule 497(c), are not filed.
Should the Staff have any questions relating to the foregoing, please
contact the undersigned at 312/853-2238.
Very truly yours,
/s/ Joseph Schohl
