Net Income (Loss) Per Share (EPS)	Note 5 - Net Income / Income Per Share (“EPS”): Basic income per share is calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted income per share is calculated by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period and, when dilutive, potential shares from stock options and warrants to purchase common stock, using the treasury stock method. Common stock equivalents are included in the diluted income per share calculation only when option exercise prices are lower than the average market price of the common shares for the period presented. The weighted average number of common stock equivalents not included in diluted income per share, because the effects are anti-dilutive, was 850 for the six months ended January 31, 2018. The weighted average number of common stock equivalents not included in diluted loss per share, because the effects are anti-dilutive, was 1,534,095 for the three months ended January 31, 2018. For the three and six-month periods ended January 31, 2017 all outstanding stock options, non-vested restricted stock, warrants and common stock underlying convertible preferred stock, representing 375,972 incremental shares at January 31, 2017, have been excluded from the computation of diluted EPS as they are anti-dilutive.
