Earnings Per Share [Abstract]  
Earnings Per Share

Earnings 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:

Three Months Ended March 31,
(in thousands, except per share amounts)
2022 2021
Weighted average common shares outstanding, used in computing basic earnings per share
64,273  66,363 
Effect of dilutive stock options and restricted stock units 318  522 
Weighted average common shares outstanding, used in computing diluted earnings per share
64,591  66,885 
Earnings per share:
Basic $ 1.04  $ 0.84 
Diluted $ 1.03  $ 0.84 
Stock options, service-based restricted stock units, and performance-based restricted stock representing 1,230,716 and 693,403 shares of common stock for the three months ended March 31, 2022 and 2021, respectively, were outstanding but were excluded from the computation of diluted EPS because their effect would be anti-dilutive under the treasury stock method or because the shares were subject to performance conditions that had not been met.
