Re: Aon Funds (the "Trust")
File Nos. 811-6422 and 33-43133
Ladies and Gentlemen:
We refer to Amendment No. 14 under the Investment Company Act of
1940, as amended, and Post-Effective Amendment No. 13 under the Securities Act
of 1933, as amended, to the Registration Statement on Form N-1A of the Trust
(the "Amendment"), which was filed and became effective on March 1, 1999. The
Amendment is the most recent amendment filed by the Trust.
The Trust 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
materially 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 Trust
under Rule 497(c), are not being filed.
