Earnings Per Share [Text Block]
2.
Earnings Per Share:
 
Basic earnings per share are computed by dividing net earnings by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share are computed by dividing net earnings by the sum of (a) the weighted average number of shares of common stock outstanding during the period and (b) the dilutive effect of potential common stock equivalents during the period. Stock options and unvested service-based RSU awards make up the common stock equivalents and are computed using the treasury stock method.
