| Earnings Per Share Our basic earnings per share calculations are based on the weighted average number of common shares outstanding during the period. Potentially dilutive securities include outstanding stock options, restricted share units, deferred stock units and performance-based restricted share units. The effect of potentially dilutive securities is reflected in diluted earnings per common share by application of the treasury method. Diluted earnings per share gives effect to all potentially dilutive common shares outstanding during the period. | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three Months Ended | | Six Months Ended | | | | June 30, | | June 30, | | (in millions, except per share data) | | | | | 2026 | | 2025 | | 2026 | | 2025 | | | | | | | | | | | | | | | | | | | | | | | | | | Net income attributable to common shareholders | | | | | $ | 35.4 | | | $ | 24.9 | | | $ | 41.8 | | | $ | 46.6 | | | | | | | | | | | | | | | Average basic shares outstanding | | | | | 57.5 | | 57.4 | | 57.5 | | 57.3 | | | Effect of dilutive stock-based awards | | | | | 0.5 | | | 0.5 | | | 0.5 | | | 0.6 | | | Average diluted shares outstanding | | | | | 58.0 | | | 57.9 | | | 58.0 | | | 57.9 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earnings per basic share | | | | | $ | 0.61 | | | $ | 0.43 | | | $ | 0.73 | | | $ | 0.81 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earnings per diluted share | | | | | $ | 0.61 | | | $ | 0.43 | | | $ | 0.72 | | | $ | 0.80 | |
