The Giving Pledge, created in June by Microsoft founder Bill Gates and investor Warren Buffett, has convinced over 57 billionares to give away at least half of their fortunes. Among the list of billionares who pledged to give away half of their wealth during their lifetime or after their death includes: Facebook founders (and the world's youngest billionaires) Mark Zuckerberg and Dustin Moskovitz, AOL co-founder Steve Case, financier Carl Icahn, Morningstar CEO Joe Mansueto, private investor Ted Forstmann, businessman Nicolas Berggruen, and the imprisoned former Wall Street executive Michael Milken.
Each benefactor of the Giving Pledge is required to write a letter to publicly state their intention regarding the decision to donate half of their fortune. The Giving Pledge neither accepts money or instructs on how to donate funds but requires billionaires to make a moral commitment to philanthropy.
