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 years ended December 31, 2017, 2016, and 2015, 653,354, 386,771 and 3,239,425 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.

The 3.25% Convertible Senior Notes (“Convertible Notes”) were not included in the computation of diluted net income (loss) per share for the year ended December 31, 2015 because there was 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.
