Earnings Per Share [Abstract] |
Net Loss Per Share | Net Loss Per Share Basic and diluted loss per common share was calculated as follows:
| For the Three Months Ended March 31, |  |
(dollars and shares in millions, except per share amounts) | 2023 |  | 2022 |  |  |  |
Net loss | $ | (81.9) |  |  | $ | (63.4) |  |  |  |  |
Weighted average number of common shares outstanding - basic and diluted | 53.3 |  |  | 53.0 |  |  |  |  |
Net loss per common share - basic and diluted | $ | (1.54) |  |  | $ | (1.20) |  |  |  |  |
The Company reported net losses for each of the three months ended March 31, 2023 and 2022, and, therefore, excluded all stock options and restricted stock units from the calculation of diluted net loss per common share as their inclusion would have had an anti-dilutive effect, as summarized below:
| For the Three Months Ended March 31, |  |
(shares in millions) | 2023 |  | 2022 |  |  |  |
Stock options | 8.2 |  |  | 6.4 |  |  |  |  |
Restricted stock units | 1.1 |  |  | 0.2 |  |  |  |  |
| 9.3 |  |  | 6.6 |  |  |  |  |
