AM Best has revised the outlook to positive from stable for the Long-Term Issuer Credit Ratings (Long-Term ICRs) and affirmed the Financial Strength Rating (FSR) of A (Excellent) and the Long-Term ICRs of “a” (Excellent) of Associated Industries of Massachusetts Mutual Insurance Company and its reinsured subsidiaries Associated Employers Insurance Company, Massachusetts Employers Insurance Company and New Hampshire Employers Insurance Company, which are members of A.I.M. Mutual Insurance Companies (A.I.M. Mutual). The outlook of the FSR is stable. All companies are headquartered in Burlington, MA.

The Credit Ratings (ratings) reflect A.I.M. Mutual’s balance sheet strength, which AM Best assesses as strongest, as well as its adequate operating performance, limited business profile and appropriate enterprise risk management.

The positive outlook for the Long-Term ICRs is driven by the group’s operational performance, which is reflective of strong underwriting results and investment income that contributes to continuous surplus growth. The group’s historically consistent favorable reserve development also was considered in the revised outlook for the Long-Term ICRs. AM Best expects A.I.M. Mutual will continue to outperform its peers on key operating metrics.

A.I.M. Mutual specializes in providing workers’ compensation insurance coverage in the commonwealth of Massachusetts and New Hampshire.
