It’s unusual for an executive to undertake such a broad philanthropic effort at so young an age. Buffett, the chairman and CEO of Berkshire Hathaway Inc. who has committed almost all of his fortune to charity, has singled out Zuckerberg as someone who can set an example for a new generation of philanthropists.

"He has an audience that’s just totally different than what I would have," Buffett, 85, said last year at a conference in Las Vegas. The Facebook co-founder previously signed the Giving Pledge, established by Buffett and Bill and Melinda Gates, in which billionaires agree to donate the majority of their fortunes to charity.

Buffett, whose current net worth is $64.2 billion, according to the Bloomberg Billionaires Index, decided to commit most of his Berkshire stock to the Bill & Melinda Gates Foundation when he was 75, after his the death of his first wife in 2004.

Before devoting himself to philanthropy, Gates chose to focus on his company rather than charitable efforts, much to the dismay of his own mother and local Seattle business and philanthropic leaders, Tom Alberg, co-founder of Seattle-based Madrona Venture Group, said in a recent interview. It was after the death of Mary Gates in the mid-90s that Gates began his first significant foray into charitable giving.

The Gates’s charitable foundation, now worth $41.3 billion, has given away more than $34 billion. Gates started the organization in 2000, subsuming two earlier entities: the William H. Gates Foundation and the Gates Learning Foundation. Both of the men have mentored Zuckerberg in his philanthropy efforts.

“On behalf of future generations, I thank them,” Buffett said of Zuckerberg and Chan in a statement.

There’s also one more thing in common with the philanthropic endeavors of Buffett, Gates and Zuckerberg: they reduce their tax bills, as the contributions are tax-deductible.


Track Record


Zuckerberg isn’t new to philanthropy; he’s given to several education and health-related causes in the past few years. He and his wife recently started a school in one of Silicon Valley’s disadvantaged neighborhoods and a trauma center in San Francisco General Hospital, where Chan has worked as a pediatrician. The couple this week also started a coalition with Gates to invest in sustainable energy solutions. The new Chan Zuckerberg Initiative will be a limited liability company controlled by Mark and Priscilla, the couple said.

Today, 99 percent of Zuckerberg’s Facebook holdings have a value of $45 billion. If it was all to be gifted at once that would be enough to create the largest U.S. foundation, according to data compiled by Foundation Center. The pledge also situates Zuckerberg and Chan in a century-long tradition of American philanthropists that stretches back to industrialists Andrew Carnegie and John Rockefeller, whose foundations still rank among the biggest in the country.
