Buffett's firm reports $12.8 billion loss

Warren Buffett's company has reported a nearly $13 billion loss in the third quarter as the paper value of its investments fell, but the companies it owns — particularly the insurers — generally performed well.

Berkshire Hathaway said it lost $12.8 billion in the quarter. That's significantly bigger than the $2.8 billion loss that it reported a year ago.
