Basic earnings per share of common stock is computed by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share is computed using the weighted-average number of shares of common stock outstanding during the period, plus the dilutive effect of outstanding options and warrants, using the treasury stock method, unless the effect on net earnings per share is antidilutive. The following have been excluded from the calculation of dilutive earnings per share, as the effect was antidilutive:
