NEW YORK (AP) — Famed investor Warren Buffett is donating $6 billion worth of his company's stock to five foundations, bringing the total he has given to them since 2006 to roughly $60 billion, based on their value when received. Buffett said late Friday that the shares of Berkshire Hathaway will be delivered on Monday. Berkshire Hathaway owns Geico, Dairy Queen and a range of other businesses, and Buffett is donating nearly 12.4 million of the Class B shares of its stock.
