Earnings Per Share [Abstract] |
Earnings Per Share | 7. Earnings Per Share Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income (loss) attributable to common stockholders 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 options and restricted stock units (“RSUs”) and employee stock purchase plan withholdings 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. For the three and six months ended June 30, 2014, basic and diluted weighted-average common shares outstanding were 34,320,109 and 34,246,424, respectively. During these same periods, weighted-average options and RSUs to acquire a total of 6,061,542 and 5,593,465 shares of common stock, respectively, were outstanding but not included in the computation of diluted EPS as their effect was anti-dilutive. For the three and six months ended June 30, 2013, basic and diluted weighted-average common shares outstanding were 33,915,424 and 33,816,558, respectively. During these same periods, weighted-average options and RSUs to acquire a total of 5,962,759 and 5,995,066 shares of common stock, respectively, were outstanding but not included in the computation of diluted EPS as their effect was anti-dilutive.
