Employers Holdings, Inc. Announces A.M. Best Affirms Its A- Rating

June 06, 2007 — Reno, NV — Employers Holdings, Inc. (NYSE:EIG) today announced insurance rating bureau A.M. Best has affirmed the financial strength rating (FSR) of A- (Excellent) and assigned issuer credit ratings (ICR) of ga-h to Employers Insurance Group and its two pooled property/casualty operating subsidiaries, Employers Insurance Company of Nevada and Employers Compensation Insurance Company. Concurrently, A.M. Best has assigned an ICR of gbbb-h to Employers Holdings, Inc. The outlook for all ratings is positive.

The ratings reflect the group’s superior risk-adjusted capitalization, strong operating performance, prudent reserving and strong niche position as a leading workers’ compensation carrier focused on small to medium-sized employers. Furthermore, the rating recognizes the improved financial flexibility that resulted from the group’s ultimate parent, Employers Holdings Inc., converting to a stock holding company and completing an initial public offering in February 2007, according to formal notice from A.M. Best.

The outlook reflects the expectation that operating performance and capitalization will continue to be sustained at the strong levels reported in recent years.

Chief Executive Officer Douglas D. Dirks said, “All of us at EMPLOYERS are proud of the fact that A.M. Best has affirmed our A- (Excellent) financial strength rating.”
