NOTE 2 - EARNINGS PER SHARE
 
Basic earnings per share is calculated using the weighted-average number of common shares outstanding. Diluted earnings per share reflects the potential dilution that could occur from common shares issuable through stock options and restricted stock units. For the three months ended May 31, 2015 and 2014, 12,936 and 12,936 stock options were excluded, respectively, from the computation of earnings per share because their effect would have been anti-dilutive. Restricted stock units become dilutive within the period granted and remain dilutive until the units vest and are issued as common stock.
