Berkshire Hathaway (NYSE: BRK.A) has a very ordinary quarter, but by founder Warren Buffett's standards it was awful. The company's insurance operations were hurt by hurricane claims. The other factor that damaged earnings was losses on derivatives. Buffett is supposed to think derivatives are for idiots, so it is not clear how that part happened.

Berkshire's net income fell to $1.06 billion, or $682 per Class A share, from $4.55 billion, or $2,942, in the period a year ago. Operating profit fell 18% to $2.07 billion, or $1,335 per share, from $2.56 billion, or $1,655. According to Reuters, "It fell short of analysts' average expectation for $1,429 per share, according to Reuters Estimates."

No one in his right mind would go through Buffett's 10-Q. It is as thick as the New York City phone book. The company still has an astonishing $50 billion on its balance sheet, which means Berkshire has a great deal of capital to buy companies it thinks are undervalued during the recession, a favorite Buffett habit.

For anyone who cares, the tiny Berkshire group that controls private jet company NetJets, Dairy Queen, public relations operation BusinessWire, and the Buffalo News did just fine.

How Buffett does it is anyone's guess. Who makes sure BusinessWire is doing OK?
