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 November 30, 2011 and 2010, 117,663 and 116,004 stock options, respectively, were excluded from the computation of earnings per share because their effect would have been anti-dilutive. For the nine months ended November 30, 2011 and 2010, 118,570 and 119,238 stock options, respectively, were excluded from the computation of earnings per share because their effect would have been anti-dilutive.
