A history of reinvention and business building

Our story began in the early 1980’s 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 profits exceeding $1 billion. Throughout our history we’ve been nimble and opportunist investors; as Jack once said, “You shoot ducks when ducks are flying.”
