Facebook shares are down 38% from a record $218.62 on July 25th. The criticism over the Cambridge Analytica scandal and how Facebook handles user data and polices content have soured investors on the stock. The decline robbed Zuckerberg of $32.7 billion of his net worth as of the close of trading on Wednesday, January 2nd. Zuckerberg’s sale of stock has largely been funneled into the Chan Zuckerberg Initiative, a limited liability company (rather than a charitable trust). The CZI is run by Zuckerberg and his wife Priscilla Chan. As a limited liability company, the Chan-Zuckerbergs can make both charitable donations and back political causes. Overall, CZI’s mission is to decrease inequality and spur change in health and education via technology. Mark Zuckerberg and Priscilla Chan are part of The Giving Pledge.
