Earnings Per Share [Abstract]  
Earnings Per Share
Earnings Per Share
Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. Potentially dilutive securities (consisting of warrants, stock options and RSUs calculated using the treasury stock method) are excluded from the diluted EPS computation in loss periods and when the applicable exercise price is greater than the market price on the period end date as their effect would be anti-dilutive.
The calculation of basic and diluted earnings per share was as follows (in thousands, except share and per share data):
