Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share amounts are based on the weighted average of common shares outstanding for the respective periods. Diluted earnings per share amounts are based on the weighted average of common shares outstanding plus the dilutive effect of potential common stock. Potential common stock includes outstanding partnership units exchangeable for common shares under the Continuing Offer (Note 10), outstanding options for partnership units, PSU, RSU, deferred shares under the Non-Employee Directors’ Deferred Compensation Plan, and unissued partnership units under a unit option deferral election (Note 9). In computing the potentially dilutive effect of potential common stock, partnership units are assumed to be exchanged for common shares under the Continuing Offer, increasing the weighted average number of shares outstanding. The potentially dilutive effects of partnership units outstanding and/or issuable under the unit option deferral elections are calculated using the if-converted method, while the effects of other potential common stock are calculated using the treasury method. Contingently issuable shares are included in diluted EPS based on the number of shares, if any, that would be issuable if the end of the reporting period were the end of the contingency period.
