Our board of directors may establish the authorized number of directors from time to time by resolution. The current authorized number of directors is eight. Our current directors, if elected, will continue to serve as directors until the next annual meeting of stockholders and until his or her successor has been elected and qualified, or until his or her earlier death, resignation, or removal.
Our board of directors held seven meetings during 2013. The board of directors also acted eleven times by unanimous written consent. No member of our board of directors attended fewer than 75% of the aggregate of the total number of meetings of the board of directors (held during the period for which he or she was a director) and the total number of meetings held by all committees of the board of directors on which such director served (held during the period that such director served). Members of our board of directors are invited and encouraged to attend each annual meeting of stockholders.
Board Leadership Structure
Mark Zuckerberg, our founder and CEO, serves as Chairman of our board of directors and presides over meetings of the board of directors, and holds such other powers and carries out such other duties as are customarily carried out by the Chairman of our board of directors. Mr. Zuckerberg brings valuable insight to our board of directors due to the perspective and experience he brings as our founder and CEO, and as our largest and controlling stockholder. Mr. Graham serves as our Lead Independent Director and presides over portions of regularly scheduled meetings at which only our independent directors are present, serves as a liaison between the Chairman and the independent directors, and performs such additional duties as the board of directors may otherwise determine and delegate. Mr. Graham is also chair of our compensation committee and a member of our governance committee. Generally, every regular meeting of our board of directors includes a meeting of our independent directors without management present.
Controlled Company Status
Because Mr. Zuckerberg controls a majority of our outstanding voting power, we are a “controlled company” under the corporate governance rules of the NASDAQ Stock Market LLC (NASDAQ). Therefore, we are not required to have a majority of our board of directors be independent, nor are we required to have a compensation committee or an independent nominating function. In light of our status as a controlled company, our board of directors has determined not to have an independent nominating function and to have the full board of directors be directly responsible for nominating members of our board.
