Over many decades, White Mountains has owned and operated a broad range of companies, including property & casualty insurers, life insurers, brokerages, financial guarantors, reinsurers, service companies and investment advisors. We have also invested in adjacent or related businesses, including consumer, media and technology companies that have an insurance or financial services-related component. Daily, we examine the full set of current opportunities but always with an eye toward what might lay around the bend.
