Profits drop at Warren Buffett's Berkshire Hathaway as it writes down its Kraft Heinz investment

Warren Buffett's company reported less than half as much profit in the second quarter as it took a $3.76 billion writedown on the value of its stake in Kraft Heinz, as that iconic food producer considers largely undoing the merger that Berkshire Hathaway helped bankroll. Berkshire said it earned $12.37 billion, or $8,601 per Class A share, during the quarter. Berkshire's earnings can swing wildly from quarter to quarter because it has to record the current value of its massive investment portfolio even though it doesn't sell most of the stocks.
