(Reuters) - Warren Buffett on Tuesday said the anonymous bidder who agreed last week at an annual charity auction to pay $3,456,789 (£2.45 million)to have lunch with him, matching the previous record high, is a woman.
"The one thing I will tell you, because we're in this crowd: It's a woman," Buffett, the billionaire chairman of Berkshire Hathaway Inc, said at a United State of Women conference in Washington.
