Earnings Per Share [Abstract] |
Earnings Per Common Share | Note 16 — Earnings Per Common Share Basic and diluted earnings per common share are computed by dividing net income by the weighted-average number of basic and diluted common shares outstanding, respectively. The weighted-average number of diluted common shares includes the impact of dilutive securities, including outstanding stock options and unvested restricted stock and restricted stock units. The table below reconciles the weighted-average basic and diluted common shares outstanding for 2020, 2019 and 2018:
| Year Ended December 31,
| 2020 |  | 2019 |  | 2018
| (in thousands)
Weighted average number of common shares outstanding - basic | 74,696 |  |  | 74,362 |  |  | 74,002 |
Effect of dilutive securities 1 | 89 |  |  | 228 |  |  | 610 |
Weighted average number of common shares outstanding - diluted | 74,785 |  |  | 74,590 |  |  | 74,612 |
1.Certain outstanding equity awards are anti-dilutive and therefore were excluded from the calculation of the weighted average number of diluted common shares outstanding. Anti-dilutive outstanding equity awards under share-based compensation plans were as follows:
| Year Ended December 31,
| 2020 |  | 2019 |  | 2018
| (in thousands)
Anti-dilutive | 2,121 |  |  | 1,682 |  |  | 659 |
