According to the filing, Breyer told Facebook he would not be standing for re-election at the annual stockholders meeting three days ago. The stockholder meeting is on June 11, and Breyer will remain on Facebook's board until then.
Breyer sold a large chunk of stock in the company – worth $81 million – last November. He led Accel's investment in Facebook in 2005.
Breyer says his departure is the result of other responsibilies getting in the way, such as his recent election to the Harvard University Corporation Board.
