Earnings Per Share [Abstract] |
Earnings Per Share [Text Block] | 5. Net Income (Loss) Per Share The Company calculates basic income (loss) per share by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings (loss) per share reflects the effects of potentially dilutive securities. Since the Company incurred a net loss for the three and six months ended July 31, 2013, basic and diluted loss per share for those periods were the same because the inclusion of dilutive potential common shares related to outstanding stock awards in the calculation would have been antidilutive. Potential common shares of 768,826 relating to outstanding stock awards to directors and employees have been excluded from diluted weighted average common shares for the six months ended July 31, 2013, as the effect would have been antidilutive. Additionally, for the three and six months ended July 31, 2013 the 1,704,546 outstanding warrants issued to Broadwood and the 6,000,000 potential shares issuable to Elkhorn upon debt conversion, would have been anti-dilutive. The following table presents reconciliations of the numerators and denominators of the basic and diluted loss per share computations for net loss. In the tables below, “Net income (loss)” represents the numerator and “Shares” represents the denominator (in thousands, except per share amounts):
