Apple CEO Tim Cook is giving hundreds of millions of dollars to charity.
Cook, who is close to becoming a billionaire, says he will pay for his nephew's college education, then donate the rest of his wealth to philanthropic projects, according to Fortune.
Cook isn't the first top executive to give his money away.
Warren Buffett and Bill Gates launched The Giving Pledge in 2010 -- a campaign to persuade billionaires to give at least half of their fortunes to charity. More than a hundred have signed up so far, including Michael Bloomberg and Facebook 's Mark Zuckerberg.
Others, like Cook, are going their own way. Last year, Alibaba co-founder Jack Ma started a multi-billion dollar charity.
Cook certainly has plenty of funds to give away. His pay at Apple more than doubled last year to $9.2 million, according to a regulatory filing. In 2014, $145 million worth of stock awards vested, and he's got another $536 million in stock awards to come.
Cook, who came out last year, also told Fortune that he felt his sexuality was a "yawner," especially internally at Apple.
