8.         NET INCOME (LOSS) PER SHARE OF COMMON STOCK

Basic net income (loss) per common share (“Basic EPS”) is computed by dividing net income (loss) by the weighted average number of common shares outstanding.  Diluted net income (loss) per common share (“Diluted EPS”) is computed by dividing net income (loss) by the weighted average number of common shares and dilutive common share equivalents and convertible securities then outstanding.  The treasury stock method reduces the dilutive effect of potentially dilutive securities as it assumes that any cash proceeds (from the issuance of potentially dilutive securities) are used to buy back shares at the average share price during the period.

Diluted EPS for all periods presented is the same as Basic EPS, as the inclusion of the effect of common share equivalents then outstanding would be anti-dilutive.  For this reason, excluded from the calculation of Diluted EPS for the nine and three months ended July 31, 2018 and 2017, were stock options to purchase 7,238,446 and 3,378,606 shares, respectively, and warrants to purchase 854,400 and 829,400 shares, respectively.
