Earnings Per Share [Abstract] |
Net Loss per Common Share | Net Loss per Common Share Basic and diluted net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding. Since the Company was in a loss position for all periods presented, diluted net loss per share is the same as basic net loss per share. The numerator and denominator used in the calculation of basic and diluted net loss per common share are as follows:
|  | Three months ended March 31, |  |
(in thousands, except per share data) |  | 2022 |  | 2021 |  |  |  |

Weighted average common shares outstanding |  | 141,675 |  |  | 127,401 |  |  |  |  |
Net loss per common share (expressed in $ per share) |  | $ | (0.27) |  |  | $ | (0.40) |  |  |  |  |
