Earnings Per Share [Abstract] |
Net Income per Share | Net Income (Loss) per Share The Company computes basic net income (loss) per share by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding, such as stock options and unvested restricted stock units and awards, during the period using the treasury stock method. The table below reconciles the weighted-average common shares used to calculate basic net income (loss) per share with the weighted-average common shares used to calculate diluted net income (loss) per share:
