Earnings Per Share [Abstract]  
Earnings (Loss) Per Share Earnings (Loss) Per Share
Basic earnings (loss) per share is computed by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period.
In periods when we report net income, diluted earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period plus the dilutive effect of our outstanding stock incentive awards. For periods when we report a net loss, diluted earnings per share is equal to basic earnings per share, as the impact of our outstanding stock incentive awards is considered to be antidilutive.
The following table sets forth the computation of basic and diluted earnings (loss) per share:
