Berkshire Hathaway and the financial reform bill

CNBC article

Buffet is fine with having everyone post margin on their derivative contracts from now one - just not for contracts they have already entered into.
But if you are "in the money" on the contracts you have already entered into then you would receive money back.

My conclusion is that Berkshire Hathaway is under water on the billions of dollars of derivative contracts that it has made?  Is my logic wrong?
