Earnings per share [abstract]  
Earnings per share

Basic and diluted

 

Basic earnings per share is calculated by dividing the equity attributable to Company’s owners by the weighted average number of outstanding common shares during the year.  The Company does not have potentially dilutive common shares outstanding or debts convertible into common shares.  Accordingly, basic and diluted earnings per share are equal.
