Berkshire Hathaway (BRK.A), the investment firm run by Warren Buffet, took $2.25 billion in dividends from Burlington Northern in less than 13 months of ownership, reports Bloomberg. That amount is nearly triple the payout from the railroad prior to the firm's acquisition of it in February of last year. Berkshire Hathaway's B shares are down 0.75%, or $0.65, to $85.70.
