A.M. Best Affirms Rating for State Auto Insurance Cos.

A.M. Best Co. has affirmed the financial strength ratings of A+ (Superior) of State Auto Insurance Companies (State Auto) (Columbus, Ohio) and assigned it an issuer credit rating (ICR) of “aa-“. A.M. Best has also affirmed the debt rating of “a-” on the $100 million 6.25% senior unsecured notes issued by State Auto Financial Corporation (Columbus) and its ICR of “a-“.

Concurrently, A.M. Best has upgraded the financial strength rating to A+ (Superior) from A (Excellent) of Meridian Citizens Mutual Insurance Company (Meridian Citizens) and Meridian Security Insurance Company (Meridian Security) (both of Indianapolis, Ind.). As of Jan. 1, 2005, Meridian Citizens and Meridian Security were added to the State Auto pool and as such, now carry the pool rating. The outlook for all ratings remains stable.

The ratings reflect State Auto’s strong capitalization, generally favorable earnings and excellent regional market franchise. These attributes reflect its long-standing market presence, well-established agency relationships, diversified product offerings and adherence to sound underwriting fundamentals.

Somewhat offsetting these positive rating factors include variability in operating results in recent years, which reflects weather-related losses, rising loss costs and adverse loss reserve development on the Meridian business. In addition, the pool will have debt servicing requirements due to the above mentioned debt issuance, which could put a strain on future earnings. However, State Auto has implemented numerous initiatives to improve earnings, which includes re-underwriting, pricing adjustments and agency management actions.

As a result of these actions, firm market conditions and the recent improvement in loss reserve development related to the Meridian business, State Auto’s operating results improved significantly in 2003 and 2004.
