Our enduring principles
A history of business building and reinvention
Our story began in the early 1980s when Jack Byrne was recruited by American Express to turn around troubled property and casualty insurer Fireman’s Fund. When Jack took Fireman’s Fund public in 1985, it was the largest IPO in American history, and when the insurer was sold to Allianz six years later, shareholders were rewarded with gains exceeding $1 billion. Throughout our history, we’ve been nimble and opportunistic investors; as Jack often said, “You shoot ducks when ducks are flying.”
Jack Byrne takes Fireman’s Fund public at $25.75 per share.
