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 at October 31, 2017. Basic EPS and diluted EPS for the three-month period ended October 31, 2016 have been computed by dividing the net income available to common stockholders for the period by the weighted average shares outstanding during the period. All outstanding stock options, non-vested restricted stock, warrants and common stock underlying convertible preferred stock, representing 401,373 incremental shares at October 31, 2016, have been excluded from the computation of diluted EPS as they are anti-dilutive.

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 at October 31, 2017.

Basic EPS and diluted EPS for the three-month period ended October 31, 2016 have been computed by dividing the net income available to common stockholders for the period by the weighted average shares outstanding during the period. All outstanding stock options, non-vested restricted stock, warrants and common stock underlying convertible preferred stock, representing 401,373 incremental shares at October 31, 2016, have been excluded from the computation of diluted EPS as they are anti-dilutive.
