Earnings Per Share [Text Block] |
Basic and diluted weighted-average shares outstanding for the periods ended September 30, 2018 and 2017 were as follows:
Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted net income (loss) per common share is computed similar to basic net income (loss) per common share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares from share-based compensation arrangements had been issued. Potentially dilutive shares arise from non-qualified stock options to purchase common stock. The treasury stock method is utilized to determine the number of potentially dilutive shares related to the outstanding non-qualified stock options. |
