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 unvested share awards, units convertible into common shares, and shares which could be settled under equity forward sales agreements. 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. Common shares under a forward sales agreement will be considered in our calculation for diluted earnings-per-share until settlement, using the treasury stock method. The number of common share equivalent securities excluded from the diluted earnings per share calculation were approximately 1.9 million for each of the three months ended March 31, 2021 and 2020. 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:
