Mark Zuckerberg will put 99 percent of his Facebook Inc (FB.O) shares, currently worth about $45 billion, into a new philanthropy project focusing on human potential and equality, he and his wife said Tuesday in a letter to their newborn daughter. The plan, which was posted on the Facebook founder and chief executive officer’s page and has attracted more than 360,000 ‘likes’, follows other high-profile billionaires such as Warren Buffett and Bill and Melinda Gates, who have set up foundations to dedicate their massive fortunes to philanthropic endeavors.
