AOC Aon Corp.

A.M. Best Co. has affirmed the financial strength rating (FSR) of A- (Excellent) and the issuer credit ratings (ICR) of �a-� of Virginia Surety Company, Inc. (Virginia Surety) (Chicago, IL) and FFG Insurance Company (FFG) (Texas). Additionally, A.M. Best has affirmed the FSR of B++ (Very Good) and ICR of �bbb� of Resource Life Insurance Company (Resource) (Illinois). The outlook for all ratings is stable. These rating actions follow the November 30, 2006 completion of the acquisition by ONEX Corporation of the Aon Warranty Group from Aon Corporation (Aon) (Chicago, IL) [NYSE: AOC]. This acquisition includes Virginia Surety and Resource Life. FFG is not included in the acquisition and will be strictly in run off going forward. Virginia Surety and FFG will no longer maintain a group rating. The rating affirmations of Virginia Surety reflect its business plan to focus exclusively on extended warranty writings and the excellent track record of its management team in running profitable warranty operations. The ratings also take into consideration the company�s solid capitalization, as well as the loss portfolio reinsurance agreement entered into with FFG prior to the transaction, which covers all specialty property/casualty prior year reserves. Aon is providing an unlimited guarantee and indemnification to Virginia Surety for the run-off of the specialty property/casualty reserves. The rating affirmations of FFG reflect its adequate capitalization and the expectation that all specialty property/casualty liabilities will be run off in an orderly fashion. An analysis of FFG�s current and pro-forma cash flows indicates that sufficient capital exists to support its existing financial obligations. The ratings of Resource reflect its strategic relationship with Virginia Surety. For Best�s Ratings, an overview of the rating process and rating methodologies, please visit www.ambest.com/ratings.
