Warren Buffett, the second-richest person in the US, made his largest single charitable contribution with a gift of $2.1 billion (NZ$2.4 billion) to the Bill and Melinda Gates Foundation as he seeks to encourage giving by the wealthy.
The chairman and chief executive officer of Omaha, Nebraska-based Berkshire Hathaway gave 16.6 million Class B shares on Monday in an annual gift to the foundation, where he is a trustee, according to a regulatory filing on Tuesday. The donation beat last year's record gift of $2 billion, when he gave 17.5 million shares. The stock has gained 8.4 per cent this year to $128.49 as of Tuesday's market close.
Buffett, 83, has urged the ultra-wealthy to give away more money. He and Gates helped found the Giving Pledge, which asks billionaires including Mark Zuckerberg, the CEO of social media giant Facebook, to donate the majority of their wealth to charity. More than 120 have agreed.
"Now we're starting to get a few members from outside the United States, as well," Buffett said June 9 at the Edison Electric Institute annual convention in Las Vegas. "It can't be a bad thing and I think it will turn out to be quite a good thing."
The investor's wealth soared this year to more than $65 billion before donations that were announced on Tuesday to the Gates Foundation and other charities. Bill Gates, the co-founder of Microsoft, is the world's richest man according to the Bloomberg Billionaires Index, a daily ranking of the wealthiest people.
