Earnings Per Share [Abstract] |
Earnings Per Share [Text Block] | 10. EARNINGS (LOSS) PER SHARE (EPS) We present EPS using the two-class method. This method allocates undistributed earnings between common shares and non-vested share based payment awards that entitle the holder to non-forfeitable dividend rights. Our participating securities are our non-vested restricted stock units. The following table sets forth the computation of our basic and diluted EPS available to shareholders of common stock (excluding participating securities):
| 2023 |  | 2022 |  | 2021
| (in millions, except per share data)
Numerator |  |  |  |  |
Net income (loss) | $ | (33.6) |  |  | $ | 64.3 |  |  | $ | 5.9 |
Less: Net income allocated to participating securities | — |  |  | (2.7) |  |  | (0.2) |
Net income (loss) attributable to common shareholders - Basic and Dilutive | $ | (33.6) |  |  | $ | 61.6 |  |  | $ | 5.7 |
Denominators |  |  |  |  |
Basic common shares outstanding - |  |  |  |  |
Weighted-average shares outstanding | 120.3 |  |  | 119.4 |  |  | 118.5 |
Less: Weighted-average participating securities | (3.7) |  |  | (4.9) |  |  | (4.6) |
Weighted-average common shares outstanding | 116.6 |  |  | 114.5 |  |  | 113.9 |
Effect of dilutive securities - |  |  |  |  |
Dilutive stock-based compensation | — |  |  | 1.0 |  |  | 0.2 |
Diluted shares outstanding - |  |  |  |  |
Adjusted weighted-average shares after assumed conversions | 116.6 |  |  | 115.5 |  |  | 114.1 |
Basic EPS | $ | (0.29) |  |  | $ | 0.54 |  |  | $ | 0.05 |
Diluted EPS | $ | (0.29) |  |  | $ | 0.53 |  |  | $ | 0.05 |
Basic and diluted loss per share are the same in 2023 because the effect of potentially dilutive stock-based compensation would have been antidilutive. Excluded potentially dilutive shares were 0.3 million in 2023.
