Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES Income taxes for the three months ended February 28, 2017 included $2.4 million of discrete tax benefits consisting of the following: (i) $1.6 million related to excess tax benefits associated with share-based compensation, and (ii) the reversal of unrecognized tax benefits and related interest of $0.9 million associated with the expiration of statute of limitations in various jurisdictions; offset by a $0.1 million net detriment for the revaluation of deferred tax assets related to legislation enacted in our first quarter. Other than the discrete tax benefits mentioned previously and additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the three months ended February 28, 2017. Income taxes for the three months ended February 29, 2016 included $3.8 million of discrete tax benefits consisting of the following: (i) recognition of the tax year 2015 research tax credit of $2.4 million related to new legislation enacted in our first quarter of 2016; (ii) the reversal of unrecognized tax benefits and related interest of $0.7 million associated with the expiration of statute of limitations in various jurisdictions; and (iii) a $0.7 million revaluation of a deferred tax liability related to legislation enacted in our first quarter of 2016 reducing the statutory tax rate for a non-US jurisdiction. As of February 28, 2017, we believe the reasonably possible total amount of unrecognized tax benefits that could increase or decrease in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlements would not be material to our consolidated financial statements.
