Earnings Per Share [Abstract]  
Earnings Per Share [Text Block]
Earnings per share
Basic earnings per share is calculated by dividing net income attributable to the Company by the weighted average number of common shares outstanding. Weighted average common shares outstanding include restricted stock unit awards that are no longer subject to forfeiture because the recipients have satisfied either the explicit vesting terms or retirement eligibility requirements.
Diluted earnings per share includes the dilutive effect of outstanding stock-settled stock appreciation rights and unvested stock units as computed under the treasury stock method.
The reconciliations of the numerators and denominators used to calculate basic and diluted earnings per share were as follows:
