3.	Earnings per ordinary share

Basic earnings per ordinary share is computed by dividing reported net income by the weighted-average number of ordinary shares outstanding during each period. Diluted earnings per ordinary share is computed by calculating the effect of potential dilutive ordinary shares outstanding during the period using the treasury stock method. Dilutive ordinary equivalent shares consist of share options, restricted share units and performance share units. Earnings per ordinary share was calculated as follows:
