Warren Buffett donates $2.9 bn to Gates Foundation, family charities

Warren Buffett has donated roughly $2.9 billion of Berkshire Hathaway Inc (BRKa.N) stock to four family charities and the Bill & Melinda Gates Foundation, the latest but not largest contribution in his plan to give away his fortune.

In a statement on Wednesday, Berkshire said Buffett’s 15th annual donation comprised 15.97 million Class B shares of Berkshire.

It boosted his donations to the charities to more than $37.4 billion since Buffett, who turns 90 on Aug. 30, began giving his Berkshire shares away in 2006.

Four-fifths of the donations go to the Gates Foundation. The rest goes to the Susan Thompson Buffett Foundation,
