Earnings Per Share [Abstract] |
NET INCOME (LOSS) PER SHARE | NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the three and six months ended June 30, 2017, 852,176 and 1,426,480 common stock equivalents, respectively, related to equity-based awards were not included in the diluted earnings per share calculation as the shares would be antidilutive. Similarly, 439,721 and 1,600,669 common stock equivalents were excluded from the diluted earnings per share calculation for the three and six months ended June 30, 2016, respectively. The 3.25% Convertible Senior Notes (“Convertible Notes”) were not included in the computation of diluted net income (loss) per share for the three and six months ended June 30, 2016 because there is no excess value upon conversion over the principal amount of the Convertible Notes. The outstanding Convertible Notes were redeemed in the third quarter of 2016.
