Warren Buffett has donated $3.2 billion of his Berkshire Hathaway stock to five different charities, he disclosed Monday.
The Bill and Melinda Gates Foundation received the most money. The others receiving money included Buffett's education charity as well as three charities chaired by his children.
Buffett plans to gradually give away his wealth, and has been donating to those five groups since 2006.
In total, he has given 27.54 billion in the last 11 years.
