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 year. Diluted EPS is computed based on the weighted average number of shares of common stock outstanding for the year plus the effect of dilutive potential common shares outstanding during the year. 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 years ended December 31, 2013, 2012, and 2011, options to purchase 0.9 million, 2.3 million, and 2.0 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.
The following table reconciles net income (loss) to basic and diluted EPS:
