Wesco Financial is sort of like Berkshire Hathaway Lite. Charlie Munger, Berkshire vice chairman and a confidante of Warren Buffett, leads Wesco. And like parent Berkshire Hathaway, the investment firm provides insurance and reinsurance; in Wesco's case, it does so through subsidiaries Wesco-Financial Insurance Company and Kansas Bankers Surety. Other prominent holdings include  CORT Business Services and Precision Steel Warehouse, which has steel service centers in Chicago and Charlotte, North Carolina. It also holds shares in some of the same companies as Berkshire Hathaway, like Coca-Cola, Kraft, Procter & Gamble, and Wells Fargo. Warren Buffett personally owns 24% of the company.
