Earnings Per Share [Abstract] |
Per Share Data | 3. Per Share Data Basic earnings per share is computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflects common shares issuable from the assumed conversion of common share options and share awards granted and units convertible into common shares. Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. Our unvested share-based awards are considered participating securities and are reflected in the calculation of basic and diluted earnings per share using the two-class method. The number of common share equivalent securities excluded from the diluted earnings per share calculation was approximately 1.4 million and 2.4 million for the three months ended September 30, 2017 and 2016, respectively, and was approximately 1.5 million and 2.5 million for the nine months ended September 30, 2017 and 2016, respectively. These securities, which include common share options and share awards granted and units convertible into common shares, were excluded from the diluted earnings per share calculations as they are anti-dilutive. The following table presents information necessary to calculate basic and diluted earnings per share for the periods indicated:
