A.M. Best Co. has assigned a financial strength rating (FSR) of A- (Excellent) and issuer credit ratings (ICR) of “a-” to AmCOMP Preferred Insurance Company (AmCOMP Preferred) and AmCOMP Assurance Corporation (AmCOMP Assurance), which now operate through an intercompany pooling agreement with Employers Insurance Company of Nevada (EICN) (Reno, NV) and Employers Compensation Insurance Company (ECIC) (Glendale, CA), collectively known as Employers Insurance Group (EMPLOYERS) (Reno, NV). The outlook assigned to these ratings is stable.

On October 31, 2008, A.M. Best affirmed the FSR of A- (Excellent) and ICRs of “a-” of EMPLOYERS and its two pooling members, EICN and ECIC. In addition, A.M. Best affirmed the ICR of “bbb-” of EMPLOYERS’ parent holding company, EHI. The outlook for these ratings was revised to stable from positive.
