Warren Buffett, the world's fourth wealthiest person with a net worth of 88-point-six billion U.S. dollars,… has pledged some 3.6 billion dollars worth of shares in his Berkshire Hathaway conglomerate to five charities.
The charities include one run by Microsoft co-founder Bill Gates and his wife Melinda Gates.
The present will be the 88-year-old's biggest donation ever, topping the 3.4 billion dollars he gave away last summer.
Buffett has now given more than 34.5 billion dollars to charities, continuing his 2016 quest to gradually donate over 99 percent of his fortune to those in need.
