Buffett lost about half of his 54 billion. How can he come through with his 38 billion commitment to the Gates foundation? Buffett was blindsided by lots of things. Has this Buffett-Gates thing been in the media?
Buffett never pledged $38 billion in <b>cash</b> in the first place. $38 billion was the approximate value of the Berkshire stock he pledged at the time.
He pledged $3B a year contingent on him being satisfied with what the foundation did with the money each year.
