Net Earnings (Loss) Per Share [Abstract]

Net Earnings (Loss) Per Share

17. NET EARNINGS (LOSS) PER SHARE

Basic net earnings (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net earnings per share is computed using the weighted-average number of common shares outstanding during the period, plus the dilutive effect of outstanding options, warrants and RSUs, 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, warrants, 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.
