Accounting for Stock-Based Compensation

Options granted are priced at the fair market value of the Company's stock on the date of grant. There were 941,350 of stock options awarded during the six months ended January 31, 2016. The weighted average fair value for options granted during the six months ended January 31, 2016 and 2015 was $7.08 and $9.95 per share, respectively. For the three and six months ended January 31, 2016, the Company recorded pre-tax stock-based compensation expense associated with stock options of $3.3 million and $4.4 million, respectively, and recorded $1.1 million and $1.4 million, respectively, of related tax benefits.
