Sandberg's donation to her donor advised fund comprised 880,000 of Class "A" shares of Facebook, according to a regulatory filing on Wednesday. The donation was made on November 21, according to the filing.
This comes months after Facebook founder Mark Zuckerberg and his wife Priscilla Chan said they would donate more than $3 billion toward a plan to "cure, prevent or manage" disease.
In December 2015, Zuckerberg made one of the largest pledges in history when he and his wife said they would donate 99 percent of their company shares to charity.
Sandberg's donation will be used to fund LeanIn.Org, her nonprofit focused on women's empowerment, as well as OptionB.org, an initiative focused on helping people build resilience after experiencing loss, the Wall Street Journal reported citing people familiar with the matter. http://on.wsj.com/2fNQkV5
The couple, married for 11 years, had two children together, a son and daughter. Last July, Sandberg joined the board of Survey Monkey, the online polling company that had been run by her husband.
