OMAHA, Neb. (AP) — Investor Warren Buffett has delivered his annual gifts of Berkshire Hathaway stock to five charities as part of his plan to gradually give away his fortune.

The gifts of Class B Berkshire stock that Buffett disclosed Thursday were worth roughly $2.86 billion. More than 19.6 million Berkshire shares were donated.

That’s slightly more than last year’s $2.8 billion donation even though fewer shares are involved because Berkshire’s stock price has increased.

Buffett has been giving away blocks of Berkshire stock since 2006 with the biggest share going to the Bill and Melinda Gates Foundation.

He also gave Class B Berkshire shares to his own foundation and to the foundations run by each of his three children.
