Wesco Financial Corporation was a diversified financial corporation headquartered in Pasadena, California.
Wesco was originally the holding company for Mutual Savings, a savings and loan association. Mutual Savings' thrift operations were sold to CenFed Bank in 1993. It was for a long time 80.1% owned by Blue Chip Stamps, which is wholly owned by Berkshire Hathaway, which is controlled by legendary investor Warren Buffett. Charlie Munger, the vice-chairman of Berkshire Hathaway and Buffett's business partner, served as CEO and Chairman of Wesco from 1984 to 2011. Munger, formerly a practicing attorney, is known for his straight-shooting style and his conduct at the now discontinued Wesco shareholder meetings in Pasadena, where he used to interact with the outside investors at considerable length. In June 2011 Berkshire Hathaway acquired the approximately 20% of Wesco that it did not already own.Wesco Financial was previously likened to a miniature version of Berkshire Hathaway by certain observers, although Buffett and Munger cautioned investors that this was not an appropriate comparison. Like its parent company, Wesco provided insurance and reinsurance; it does so through subsidiaries Wesco-Financial Insurance Company and Kansas Bankers Surety. It also held shares in some of the same companies as Berkshire, like Coca-Cola, Kraft Foods, Procter & Gamble, and Wells Fargo. Controlling interests include CORT Business Services and Precision Steel Warehouse, which has steel service centers in Chicago and Charlotte, North Carolina.
