Policies
Stock-based Compensation	Stock-Based Compensation The Company follows FASB ASC 718, “Compensation-Stock Compensation,” which requires the measurement of compensation cost for all stock-based awards at fair value on the date of grant, and recognition of stock-based compensation expense over the service period for awards expected to vest. The fair value of stock options was determined using the Black-Scholes valuation model. Such fair value is recognized as an expense over the service period, net of forfeitures. Stock-based compensation expense was $171,000 and $342,000 for the three and six months ended April 30, 2018, respectively. For the three and six months ended April 30, 2017, stock-based compensation expense was $113,000 and $255,000, respectively. Stock-based compensation is primarily included in selling, general, and administrative expenses.
