Earnings Per Share

9 Months Ended

Sep. 30, 2022

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. Potentially dilutive common shares are excluded from the computations of diluted earnings per share if their effect would be anti-dilutive. For the three months ended September 30, 2022, the Company had a net loss attributable to common shareholders which causes all potentially dilutive securities to be anti-dilutive and are therefore not included in the calculation of earnings per share.

The computation of diluted earnings per share excludes the effect of the potentially anti-dilutive securities which was 1.2 million and 1.0 million for the three months ended September 30, 2022, and 2021, respectively, and 0.4 million and 1.4 million for the nine months ending September 30, 2022 and 2021, respectively.
