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. The dilutive effect of potential common shares, consisting of outstanding stock options and unvested restricted stock, is determined using the treasury stock method. Diluted weighted average shares outstanding for the three months ended October 31, 2013 and 2012 do not include the potential common shares from stock options and unvested restricted stock because to do so would have been antidilutive, and as such is the same as basic weighted average shares outstanding. During the three months ended October 31, 2013 and 2012, potential shares from unvested restricted stock excluded from the computation of diluted net loss per share were approximately 51,000 and 0 shares, respectively. For the three months ended October 31, 2013 and 2012 the effect of approximately 723,000 and 686,000 shares respectively, of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. |
