AM Best Rating System

AM Best issues a Best's Credit Rating (BCR) that rates both financial strength and issuer credit. The former indicates Best's assessment of an insurer's ability to meet its obligations to policyholders. It takes into account both qualitative and quantitative assessments of the balance sheet, operating performance, and business profile. Best has six secure ratings, ranging from the highest A++ to B+, and 10 vulnerable ratings, ranging from B to S, with the lowest indicating a rating was suspended.

Long-term credit ratings reflect the company's ability to pay its commitments maturing in more than a year, and range from AAA (exceptional) to D (in default).

Criticism of AM Best

In Sept. 2008, the financial market crisis hit insurance holding company American International Group (AIG) hard, as enormous losses at its derivative trading subsidiary, AIG Financial Products, threatened to bring down the entire company, including the dozens of insurance companies that it owned. The holding company's stock fell dramatically, and rating agencies were forced to quickly and aggressively cut the company's rating. The federal government took over and bailed out the company with $182 billion of financial support, which was repaid in full by the end of February 2013.

The rating agencies, including AM Best, were sharply criticized for not recognizing sooner the risk that AIG's aggressive trading operations created. Best cut AIG's financial strength rating to A+ (superior) from A++ (superior) and issuer credit ratings to "aa" from "aa+" as the company faced collapse.
