We have three classes of directors serving staggered three-year terms. Our Board is presently composed of seven directors. Class I and Class III currently consist of two directors and Class II currently consists of three directors. One Class III director was elected at the 2013 Annual Meeting of Stockholders to serve until our 2016 Annual Meeting of Stockholders. One Class II director and one Class III director were appointed at the Board meeting immediately following the 2013 Annual Meeting of Stockholders. The terms of the Class I and Class II directors expire at our 2014 and 2015 Annual Meetings of Stockholders, respectively.
