Earnings Per Share [Abstract]  
Earnings Per Share
EARNINGS PER SHARE
Basic earnings per share (“EPS”) is computed based on the weighted-average number of shares of common stock outstanding. Diluted EPS is computed based on the weighted-average number of shares of common stock outstanding plus common stock equivalents assuming exercise of stock options, where dilutive. Stock-based awards of approximately 3.0 million and 3.3 million were outstanding during the three and nine month periods ended September 30, 2017, respectively, and approximately 2.5 million shares were outstanding during the three and nine month periods ended September 30, 2016, respectively, but were excluded from the calculation of diluted EPS for the periods then ended because the effect of the awards is anti-dilutive. In 2016, shares issuable from stock-based awards of 0.8 million for both the three and nine month periods ended September 30, 2016 were excluded from the computation of shares contingently issuable upon exercise as we recognized a net loss. The following is a calculation of basic and diluted earnings per share and weighted-average shares outstanding (in thousands, except per share amounts):
