Net Earnings Per Share
 
Basic earnings per share has been calculated by dividing net earnings by the weighted average number of common shares outstanding during each period. For purposes of calculating diluted earnings per share, shares issuable under employee and director stock options were considered potential common shares and were included in the weighted average common shares unless they were anti-dilutive.
 
The computation of basic and diluted earnings per common share is as follows:
