Warren Buffett donates $4 billion to charity

(Reuters) -Warren Buffett on Tuesday donated about $4 billion to the Bill & Melinda Gates Foundation Trust and four family charities, part of the billionaire’s pledge to give away nearly all of his net worth. Berkshire Hathaway Inc, which Buffett has run since 1965, said the donation comprises about 14.4 million of its Class B shares, whose closing price on Tuesday was $277.64. Eleven million shares will go to the Bill & Melinda Gates Foundation, and 1.1 million will go to the Susan Thompson Buffett Foundation, named for Buffett’s late first wife.
