Heritage
White Mountain Insurance Group began in the early 1980s by
John J. Byrne, the man recruited by American Express to turn around troubled property and casualty insurer Fireman's Fund.
When Byrne took Fireman's Fund public in 1985, it was the largest IPO in American history, and the insurer was sold to Allianz six years later. Upon completion of the Fireman's Fund sale in 1991, the remaining holding company and residual assets formed the starting point for the future White Mountains.
In December 2020, the company reported book value per share of $1,000.
