Note 2 – Net loss per share Basic net income (loss) per share represents net income (loss) divided by the weighted average number of common shares outstanding during the period. As a result of the net loss for each of the three and nine month periods ended April 30, 2015 and 2014, diluted weighted average shares outstanding are the same as basic weighted average shares outstanding, and do not include the potential common shares from stock options and unvested restricted stock because to do so would be antidilutive. For the three and nine months ended April 30, 2015, approximately 1,358,000 and 1,113,000 weighted average stock options were excluded from the determination of diluted weighted average shares outstanding. For the three and nine months ended April 30, 2014, approximately 1,172,000 and 905,000 weighted average stock options were excluded from the determination. For the three and nine months ended April 30, 2015, approximately 26,000 shares of unvested restricted stock were excluded from the determination of diluted weighted average shares outstanding. For the three and nine months ended April 30, 2014, approximately 52,000 shares of unvested restricted stock were excluded from the determination. |
