EARNINGS PER SHARE

11.   EARNINGS PER SHARE

Basic earnings per share is computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted-average number of common shares outstanding during the period, plus the dilutive effect of outstanding options, RSUs, and warrants, using the treasury stock method and the average market price of our common stock during the applicable period. Certain shares related to some of our outstanding stock options and RSUs were excluded from the computation of diluted earnings per share because they were antidilutive in the periods presented, but could be dilutive in the future.
