Aon Responds to Speculation in Subscription Newsletter

Aon Corporation recently stated that it is not aware of any formal or informal investigation being conducted by the SEC’s Division of Enforcement despite speculation to that effect in a subscription newsletter dated July 10, 2002.

Aon received a comment letter from the SEC’s Division of Corporation Finance dated July 3, 2002 addressing financial statements and related disclosures in Aon’s 2001 Form 10-K and first quarter 2002 Form 10-Q. Aon said it will reply shortly to the SEC’s letter.

Aon will report second quarter 2002 earnings in early August and host its investor conference call on the same day.
