Earnings Per Share [Text Block]
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 August 31, 2012 and 2011, 101,661 and 118,810 stock options, respectively, were excluded from the computation of earnings per share because their effect would have been anti-dilutive. For the six months ended August 31, 2012 and 2011, 103,449 and 119,024 stock options, respectively, were excluded 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.
