AM Best’s Financial Strength Ratings (FSR) represent the company’s assessment of an insurer’s ability to meet its obligations to policyholders. The rating process involves quantitative and qualitative reviews of a company’s balance sheet, operating performance and business profile, including comparisons to peers and industry standards and assessments of an insurer’s operating plans, philosophy and management. The ratings formulae are proprietary.
The ratings scale includes six "Secure" ratings:
A++, A+ (Superior)
A, A- (Excellent)
B++, B+ (Good)
The scale also includes ten ratings for companies deemed "Vulnerable":
B, B- (Fair)
C++, C+ (Marginal)
C, C- (Weak)
D (Poor)
E (Under Regulatory Supervision)
F (In Liquidation)
S (Rating Suspended)
There are many companies that A.M. Best follows but does not issue a Best’s Credit Rating on. These companies are designated as Not Rated (NR).
Long-Term Credit Ratings assess the ability of an insurance company, holding company or other legal entity to meet its senior obligations. Ratings from "aa" to "ccc" sometimes are enhanced with a "+" (plus) or "-" (minus) to indicate whether the issuer is near the top or bottom of a category, and may be designated as Under Review ("u") when recent positive, negative or developing events dictate the rating may be subject to change in the near-term.
