During the year ended December 31, 2011, the Company granted two stock option awards totaling 53,720 shares that vest 100% on the fifth anniversary of the grant date. Because the Company did not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term for these grants, the Company utilized the simplified method in developing an estimate of the expected term of these options.
