Earnings Per Share [Text Block] |
5. | Earnings Per Share:
Basic earnings per share are based on the weighted average number of common shares outstanding without consideration of common stock equivalents. Diluted earnings per share are based on the weighted average number of common and common stock equivalents. The diluted earnings per share calculation takes into account the shares that may be issued upon exercise of stock options, reduced by the shares that may be repurchased with the funds received from their exercise, based on the average price during the period. The following table sets forth the computation of basic and diluted earnings per share based upon income (loss) from continuing operations at October 31, 2012 and 2011.
