Earnings Per Share [Abstract]
Income (Loss) Per Common Share	3. Income (Loss) Per Common Share Basic earnings (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the sum of the weighted-average number of common shares outstanding during the period and the weighted-average number of dilutive common share equivalents outstanding during the period, using the treasury stock method. Dilutive common share equivalents are comprised of in-the-money stock options, warrants and restricted stock units, based on the average stock price for each period using the treasury stock method. For the three months ended April 30, 2016, the incremental dilutive common share equivalents were 9,862,858. Since we incurred a loss for the three months ended April 30, 2017 and for the nine months ended April 30, 2017 and 2016, the number of shares issuable upon the exercise of stock options, the vesting of restricted stock units, and the exercise of warrants, none of which are included in the computation of basic net loss per common share, was 13,409,795 and 18,946,821, respectively.

3. Income (Loss) Per Common Share

Basic earnings (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the sum of the weighted-average number of common shares outstanding during the period and the weighted-average number of dilutive common share equivalents outstanding during the period, using the treasury stock method. Dilutive common share equivalents are comprised of in-the-money stock options, warrants and restricted stock units, based on the average stock price for each period using the treasury stock method. For the three months ended April 30, 2016, the incremental dilutive common share equivalents were 9,862,858. Since we incurred a loss for the three months ended April 30, 2017 and for the nine months ended April 30, 2017 and 2016, the number of shares issuable upon the exercise of stock options, the vesting of restricted stock units, and the exercise of warrants, none of which are included in the computation of basic net loss per common share, was 13,409,795 and 18,946,821, respectively.
