Net Income (Loss) Per Share

9. Net Income (Loss) Per Share

 

Basic net income (loss) per share of common stock is computed based upon the number of weighted average shares of common stock outstanding as defined by ASC Topic 260, Earnings Per Share. Diluted net income (loss) per share of common stock includes the dilutive effects of stock options and stock equivalents. To the extent stock options are antidilutive, they are excluded from the calculation of diluted net income (loss) per share of common stock. For the year ended December 31, 2019, 1,021,243 of shares upon the exercise of outstanding stock options were not included in the computation of diluted net income (loss) per share for continuing operations because their inclusion would be antidilutive.

 

The following table summarizes the net income (loss) per share calculation:
