Warren Buffett has donated another $4.64 billion of Berkshire Hathaway (BRKa.N) stock to five charities, boosting his total giving since 2006 to more than $51 billion.
The annual donation made on Wednesday is the 92-year-old Buffett’s largest, and consisted of about 13.7 million of Berkshire’s Class B shares.
Buffett is donating 10.45 million shares to the Bill & Melinda Gates Foundation, which has received more than $39 billion of Berkshire stock overall.
He is also donating 1.05 million shares to the Susan Thompson Buffett Foundation, named for his late first wife, and 2.2 million shares split evenly among charities led by his children Howard, Susan and Peter: the Howard G. Buffett Foundation, the Sherwood Foundation and the NoVo Foundation.
Buffett is gradually giving away nearly all of the fortune he built at Omaha, Nebraska-based Berkshire, which he has run since 1965.
