Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share The following table presents the reconciliation of the numerator and denominator for calculating net income (loss) per share:
| Year Ended December 31,
(In thousands, except per share data) | 2021 |  | 2020 |  | 2019
Numerator |  |  |  |  |
Net loss - basic and diluted | $ | (25,526) |  |  | $ | (80,696) |  |  | $ | (12,946) |
Denominator |  |  |  |  |
Weighted average common shares outstanding - basic | 91,460 |  |  | 90,198 |  |  | 89,782 |
Dilutive effect of stock options and restricted stock awards | — |  |  | — |  |  | — |
Dilutive effect of Convertible Notes | — |  |  | — |  |  | — |
Weighted average common shares outstanding - diluted | 91,460 |  |  | 90,198 |  |  | 89,782 |
Net loss per common share |  |  |  |  |
Basic | $ | (0.28) |  |  | $ | (0.89) |  |  | $ | (0.14) |
Diluted | $ | (0.28) |  |  | $ | (0.89) |  |  | $ | (0.14) |
We excluded the following weighted-average potential shares from the calculations of diluted net loss per share during the applicable periods because their inclusion would have been anti-dilutive:
| Year Ended December 31,
(In thousands) | 2021 |  | 2020 |  | 2019
Stock options and restricted stock awards | 5,754 |  |  | 5,238 |  |  | 5,312 |
For 2021, 2020 and 2019, we excluded all potentially dilutive stock options and restricted stock awards in calculating diluted earnings per share as the effect was anti-dilutive due to the net loss incurred for these periods. The Convertible Notes, which matured in December 2021, only impacted the calculation of diluted net income per share in periods that the average price of our common stock, as calculated in accordance with the terms of the indenture governing the Convertible Notes, exceeded the conversion price of $9.33 per share.
