Understanding A.M. Best

Founded in New York City in 1899 by Alfred M. Best, the privately held company is headquartered in Oldwick, New Jersey. The company began rating insurance companies in 1899 and expanded to reporting on related news following the 1906 San Francisco earthquake.

Damage from the earthquake, which devastated much of the city, resulted in insurance claims that bankrupted 12 American companies and two more in Europe. The need for reliable information and ratings on insurers led to the company's strong growth. A.M. Best expanded to offices in the following locations: London in 1997, Hong Kong in 2000, Dubai in 2012, Mexico City in 2014, Singapore in 2015, and Amsterdam in 2018.

Criticism of A.M. 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 A.M. 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.
