This is probablly the most expensive lunch: Chinese fund manager Zhao Dan Yang won the Buffett lunch bid for $2.1 million (International Herald Tribune). The proceeds benifit Glide foundation, a San Francisco based charity formerly supported by Warren Buffett former wife Susan Buffett (Susan passed away in 2005?).
My 2 cents
I was surprised by the amount initially. This amount is almost 3 times of last year winning bid. Perhaps because Buffett is getting older? Also Mr. Zhao must have significant personal wealth to pull off that, no small change for fund managers, because fund managers make money from fees and profit sharing (2-20 rule, I will write more about fund manager fee structure later).
