Facebook COO Sheryl Sandberg has transferred 590,000 shares of Facebook stock, worth just under $100 million, to a special fund she uses for charitable donations, according to a document filed Thursday with the Securities and Exchange Commission.

The shares, which were donated at the end of July, are now part of a donor-advised fund controlled by Fidelity that lets Sandberg push the money toward organizations or causes she cares about, according to a source familiar with her plans.
