Warren Buffett

Warren Buffett donated more than $750 million in Berkshire Hathaway stock to four foundations associated with his family on Thanksgiving night, and the legendary investor says the timing is no coincidence because it’s his way of thanking his children for their charitable work.

“I have personal pride in how my kids have turned out,” Buffett told CNBC’s Becky Quick. “I feel good about the fact that they know I feel comfortable with them. This is the ultimate support in my children, and this is the ultimate statement that my children do not want to be dynastically rich.”

The 92-year-old investor donated 1.5 million of his conglomerate’s Class B shares to the Susan Thompson Buffett Foundation, named after his first wife. He also awarded 300,000 Class B shares each to three foundations run by his children: the Sherwood Foundation, the Howard G. Buffett Foundation, and the NoVo Foundation.

The recipients this time do not include the Bill & Melinda Gates Foundation. The “Oracle of Omaha” has vowed to give away his wealth from time to time and has made annual donations to the same five charities since 2006.

In June, he gave away 11 million Class B shares to the Gates Foundation, 1.1 million B shares to the Susan Thompson Buffett Foundation and 770,218 shares each to his three children’s foundations.
