Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per ShareThe numerator used in the calculation of both basic and diluted earnings per common share is net income. The denominator used in the calculation of basic earnings per common share is the weighted-average number of common shares outstanding during the period. The denominator used in the calculation of diluted earnings per common share is derived by adjusting basic shares outstanding for the dilutive effect of potential common shares outstanding, which consist of time- and performance-based stock awards and employee stock purchase plan shares. The following includes the computation of the denominator for basic and diluted weighted-average shares outstanding for the three and nine months ended September 30, 2023 and 2022:
| Three Months Ended September 30, |  | Nine Months Ended September 30,
(in thousands) | 2023 |  | 2022 |  | 2023 |  | 2022
Weighted-Average Common Shares Outstanding – Basic | 41,680 |  |  | 41,600 |  |  | 41,663 |  |  | 41,582 |

Weighted-Average Common Shares Outstanding – Diluted | 42,058 |  |  | 41,974 |  |  | 42,028 |  |  | 41,930 |
The number of shares excluded from diluted weighted-average common shares outstanding because such shares were anti-dilutive was not material for the three and nine months ended September 30, 2023 and 2022.
