Earnings Per Share [Abstract] |
Earnings per Share |
7. | Earnings per Share
Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock and vested DSUs outstanding during the year. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that diluted earnings per share includes the impact of convertible securities under the “if-converted” method if the effect of such securities would be dilutive and includes the assumed exercise of dilutive options, the assumed issuance of unvested RSUs, performance-based awards for which the performance condition has been met as of the date of determination and contingently issuable shares that would be issuable if the end of the reporting period was the end of the contingency period, using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the average unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase the Company’s common stock at the average market price during the period. The following table presents net income and reconciles basic and diluted shares outstanding used in the earnings per share computations:
| Three Months Ended June 30, |  | Six Months Ended June 30,
(in millions) | 2024 |  | 2023 |  | 2024 |  | 2023
Net income | $ | 77.0 |  |  | $ | 95.3 |  |  | $ | 142.7 |  |  | $ | 163.3 |
Weighted average common shares outstanding – Basic | 41.7 |  |  | 42.9 |  |  | 41.8 |  |  | 43.0 |
Dilutive impact of share-based compensation awards(1) | 0.3 |  |  | 0.5 |  |  | 0.4 |  |  | 0.5 |
Weighted average common shares outstanding – Diluted(2) | 42.0 |  |  | 43.4 |  |  | 42.2 |  |  | 43.5 |
(1)For the three and six months ended June 30, 2024, 0.4 million and 0.3 million, respectively, of outstanding share-based compensation awards were excluded from the computation of diluted earnings per share under the treasury stock method, as the effect of including those shares would be anti-dilutive. For the three and six months ended June 30, 2023, 0.5 million of outstanding share-based compensation awards were excluded from the computation of diluted earnings per share under the treasury stock method, as the effect of including those shares would be anti-dilutive. (2)Under the “if-converted” method, approximately 1.6 million shares of the Company’s common stock associated with the assumed conversion of the Convertible Notes were excluded from diluted shares for the three and six months ended June 30, 2023 as the effect of including such shares would have been anti-dilutive. During August 2023, the Company repurchased all of the Company’s outstanding Convertible Notes. For further information regarding the Convertible Notes and their repurchase and cancellation, see Note 10, Financing and Other Debt.
