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 years ended December 31, 2018, 2017, and 2016, 1,321,242, 653,354, and 386,771 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.
