Facebook's Sheryl Sandberg Pledges to Give Away Half Her Fortune

Ramin Talaie/Getty Images(NEW YORK) -- Facebook chief operating officer Sheryl Sandberg joined the club of billionaire philanthropists who promise to give away half of their fortunes.

Sandberg and husband Dave Goldberg guaranteed Friday to give a portion of their wealth through Giving Pledge, a commitment started by Warren Buffet and Bill and Melinda Gates in which they will donate half their money during their lifetime or upon death.

The Lean In author is among signatories such as early Google employee Craig Silverstein and his wife, Mary Obelnicki, and Kinko's founder Paul Orfalea and wife Natalie.

“We are thrilled to welcome this diverse group of business leaders and philanthropists to the pledge,” said Buffett. “They bring a wealth of expertise to the group. We will learn a lot from their experiences as we collectively aim to inspire one another to earlier and better giving.”
