NOTE 15 — 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:
|  | Year Ended December 31,
(in thousands, except per share amounts) |  | 2021 |  | 2020 |  | 2019
Weighted average common shares outstanding, used in computing basic earnings per share |  | 65,942 |  |  | 66,376 |  |  | 67,837 |
Effect of dilutive stock options and restricted stock units |  | 473 |  |  | 396 |  |  | 656 |
Weighted average common shares outstanding, used in computing diluted earnings per share |  | 66,415 |  |  | 66,772 |  |  | 68,493 |
Earnings per share: |  |  |  |  |  |
Basic |  | $ | 5.37 |  |  | $ | 1.63 |  |  | $ | 4.87 |
Diluted |  | $ | 5.33 |  |  | $ | 1.62 |  |  | $ | 4.83 |
Stock options and service-based restricted stock units, and performance-based restricted stock representing 843,578, 1,122,935 and 405,928 shares of common stock for the years ended December 31, 2021, 2020 and 2019, 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.
