Earnings Per Share [Abstract]  
Earnings (Loss) Per Share
EARNINGS (LOSS) PER SHARE
Basic earnings (loss) per share (“EPS”) is computed by dividing income or loss available to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted EPS is computed based on the weighted average number of shares of common stock outstanding for the period plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding stock options, performance-based restricted stock unit awards, and restricted stock units and reflect the potential dilution that could occur if these awards were issued and converted into common stock. We use the treasury stock method to determine the potentially dilutive impact of our employee stock options and restricted stock units, and the contingently issuable method for our performance-based restricted stock unit awards. For the three months ended March 31, 2014 and 2013, options to purchase 0.2 million and 0.9 million shares of the Company’s common stock, respectively, had an anti-dilutive effect on EPS, and accordingly, are excluded from the calculation of diluted EPS. For the three months ended March 31, 2013, no dilutive securities were included in the calculation of diluted EPS because they were antidilutive due to the net loss from continuing operations, resulting in an additional 0.8 million shares that were excluded from the calculation of diluted EPS.
The following table reconciles net income (loss) to basic and diluted EPS:
