Earnings (Loss) Per Share [Abstract] |
EARNINGS (LOSS) PER SHARE | 8. EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share (“EPS”) is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and performance stock units. For the three-month periods ended September 30, 2012 and 2011, options to purchase 2.4 million and 2.1 million shares of the Company’s common stock, respectively, had an antidilutive effect on EPS, and accordingly, are excluded from the calculation of diluted EPS. For the nine months ended September 30, 2012 and 2011, options to purchase 2.3 million and 1.9 million shares of the Company’s common stock, respectively, had an antidilutive effect on EPS, and accordingly, are excluded from the calculation of diluted EPS.
