Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES Income taxes for the three months ended May 31, 2017 included $8.3 million of discrete tax benefits consisting of the following: (i) $7.0 million related to excess tax benefits associated with share-based compensation, and (ii) and the reversal of unrecognized tax benefits and related interest of $1.3 million associated with the expiration of a statute of limitation in a non-US jurisdiction. Income taxes for the six months ended May 31, 2017 included $10.7 million of discrete tax benefits consisting of the following: (i) $8.6 million related to excess tax benefits associated with share-based compensation, and (ii) the reversal of unrecognized tax benefits and related interest of $2.2 million associated with the expiration of statute of limitations in various jurisdictions, less (iii) a net detriment of $0.1 million resulting from 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 and six months ended May 31, 2017. Income taxes for the three months ended May 31, 2016 included $6.9 million of discrete tax benefits primarily consisting of the following: (i) a reversal of a valuation allowance on an international deferred tax asset of $6.4 million due to a change in facts that favorably impacted our assessment of the likely recoverability of that deferred tax asset; and (ii) the reversal of unrecognized tax benefits and related interest of $0.2 million associated with the expiration of a statute of limitation in a non-U.S. jurisdiction. Income taxes for the six months ended May 31, 2016 included $10.7 million of discrete tax benefits, consisting of the following: (i) the valuation allowance reversal in the amount of $6.4 million described above; (ii) recognition of the tax year 2015 research tax credit of $2.4 million related to new legislation enacted in our first quarter of fiscal 2016; (iii) the reversal of unrecognized tax benefits and related interest of $0.9 million associated with the expiration of statute of limitations in various jurisdictions; and (iv) a $1.0 million revaluation of a deferred tax liability related to legislation enacted in our first quarter reducing the statutory tax rate for a non-U.S. jurisdiction. As of May 31, 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.
