A.M. Best Upgrades Ratings of American Physicians Insurance Company and Removes From Under Review

December 7, 2010

OLDWICK, N.J.--(BUSINESS WIRE)-- A.M. Best Co. has upgraded the financial strength rating to A (Excellent) from A- (Excellent) and issuer credit rating (ICR) to “a” from “a-” of American Physicians Insurance Company (API) (Austin, TX). Both ratings have been removed from under review with positive implications and assigned a stable outlook.

The rating actions follow the acquisition of American Physicians Service Group, Inc. (APS) (Austin, TX), the parent company of API, by ProAssurance Corporation (PRA) (Birmingham, AL) [NYSE:PRA] on November 30, 2010. As a new subsidiary of PRA, API will benefit from the financial flexibility and support that PRA has consistently provided to its operating companies. The ratings and outlook also reflect API’s strong risk-adjusted capital position, favorable operating performance, experienced management team and high policyholder retention levels.

A.M. Best also has withdrawn the ICR of “bbb-” of APS and assigned a category “nr” to the ICR. With the acquisition, APS became an intermediary holding company within the PRAorganization,and APS’ common stock has been de-listed from the NASDAQ Stock Market.

The principal methodology used in determining these ratings is Best’s Credit Rating Methodology -- Global Life and Non-Life Insurance Edition, which provides a comprehensive explanation of A.M. Best’s rating process and highlights the different rating criteria employed. Additional key criteria utilized include: “Risk Management and the Rating Process for Insurance Companies”; “Understanding BCAR for Property/Casualty

Insurers”; and “Rating Members of Insurance Groups.” Methodologies can be found at www.ambest.com/ratings/methodology.
