Earnings Per Share [Abstract]

Earnings per Share Policy

Basic earnings per ordinary share is computed by dividing net earnings by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per ordinary share is computed by dividing net earnings by the weighted average number of ordinary shares outstanding during the period increased by the number of additional shares that would have been outstanding related to potentially dilutive securities or instruments, if the impact is dilutive.
