|Earnings Per Share [Abstract]|
|Earnings Per Share||
s per share ("EPS") is presented on both a basic and diluted basis. Basic EPS is based on the weighted average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if outstanding securities or other contracts to issue common stock were exercised or converted into common stock.
A reconciliation of the common shares used in the denominator for computing basic and diluted EPS is as follows :
Stock options and service-based restricted stock units representing 340,741, 887,595 and 517,654 shares of common stock for the years ended December 31, 2018, 2017 and 2016, respectively, were outstanding but were excluded from the computation of diluted EPS because their effect would be anti-dilutive as a result of applying the treasury stock method. In addition, performance-based restricted stock units representing 31,775, 40,848 and 63,430 shares of common stock for the years ended December 31, 2018, 2017 and 2016, respectively, were outstanding but were excluded from the computation of diluted EPS because these shares were subject to performance conditions that had not been met.
