Buffet and Gates

[xoxoxoBruce]

In 2006 Warren Buffet donated a huge chunk of his wealth to the Gates foundation, doubling it's size. Ten years later he wrote Gates a letter(and posted it on his website) saying he'd always had profit and loss statements to gage his other investments, but since this investment isn't for profit could they tell him what they have accomplished with this investment. You can see his letter and gates response here.
