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 and six months ended January 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 and six months ended January 31, 2013 and 2012, potential shares from unvested restricted stock excluded from the computation of diluted net loss per share were approximately 23,000 and 24,000 shares, respectively. For the three and six months ended January 31, 2013 the effect of approximately 780,000 and 733,000 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. During the three and six months ended January 31, 2012, approximately 776,000 and 780,000 shares respectively were excluded from the calculation of diluted net loss per share. |
