Earnings Per Share [Abstract] |
EARNINGS PER SHARE | EARNINGS PER SHARE Basic earnings and diluted earnings per share data were computed as follows:
| Years Ended December 31,
| 2021 |  | 2020 |  | 2019
Numerator for basic and diluted earnings per share: |  |  |  |  |
Net income | $ | 161,458 |  |  | $ | 194,820 |  |  | $ | 146,527 |
Denominator: |  |  |  |  |
Weighted-average basic common shares outstanding | 40,848 |  |  | 40,035 |  |  | 38,640 |
Assumed conversion of dilutive securities: |  |  |  |  |
Stock awards | 1,382 |  |  | 1,491 |  |  | 1,465 |
Convertible Senior Notes | 14 |  |  | — |  |  | — |
Denominator for diluted earnings per share - Adjusted weighted-average shares | 42,244 |  |  | 41,526 |  |  | 40,105 |
Earnings per common share: |  |  |  |  |
Basic | $ | 3.95 |  |  | $ | 4.87 |  |  | $ | 3.79 |
Diluted | $ | 3.82 |  |  | $ | 4.69 |  |  | $ | 3.65 |
Share-based awards representing the right to purchase common stock of 117,000 shares in 2021, 132,000 shares in 2020, and 633,000 shares in 2019 were not included in the computation of diluted earnings per share because their inclusion would have had an anti-dilutive effect. We have used the if-converted method for calculating any potential dilutive effect of the Convertible Senior Notes on our diluted net income per share. Under the if-converted method, the Notes are assumed to be converted at the beginning of the period and the resulting common shares are included in the denominator of the diluted earnings per share calculation for the entire period being presented and interest expense, net of tax, recorded in connection with the Convertible Senior Notes is not added back to the numerator, only in the periods in which such effect is dilutive. The approximately 1.2 million remaining common shares related to the Notes are not included in the dilutive weighted-average common shares outstanding calculation for the twelve months ended December 31, 2021, as their effect would be anti-dilutive given none of the conversion features have been triggered. See Note 6, “Debt,” for discussion on the conversion features related to the Convertible Senior Notes.
