Equity Put Options - We're Not Going to Deleverage Berkshire

Berkshire has excess cash beyond 20 billion that we can put to work buying a business but you can't do it in an even flow. I don't think there obviously if we could unwind a derivative trade on a basis where we thought we were mathematically ahead by a significant amount we would do it. We carry a liability of well over three and a half and four billion for something that has a settlement value today of 400 million.
