Warren Buffett has given away another $6 billion. The latest philanthropic donation went largely to the Gates Foundation, with the remainder going to charities run by his children. Warren Buffett has given away the biggest chunk of his fortune since he began distributing it in 2006.

Warren Buffett has never been one to chase headlines. For most of his career, the 93-year-old billionaire investor has preferred to let his actions—and his annual shareholder letters —do the talking. But even Warren Buffett can’t give away $6 billion in a single day without people noticing.

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.
