2. | Stock Compensation
For the three and nine months ended July 31, 2016, the Company’s total stock-based compensation expense was $1.0 million and $1.8 million ($0.8 million and $1.5 million net of tax), respectively, and $2.5 million and $9.2 million ($2.0 million and $6.4 million net of tax) for the three and nine months ended July 31, 2015, respectively. Included in this total stock-based compensation was expense of $0.3 million for the three months ended July 31, 2016 and income of $1.6 million for the nine months ended July 31, 2016 related to stock options. The income was due to $2.1 million of previously recognized expense of certain performance based stock option grants for which the performance metrics are no longer expected to be satisfied, partially offset by expense from the vesting of stock options of $0.5 million, during the nine months ended July 31, 2016. Included in total stock based compensation expense for the three and nine months ended July 31, 2015 was the vesting of stock options of $0.5 million and $1.9 million, respectively.
