Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES 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; (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 reducing the statutory tax rate for a non-US jurisdiction. 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 29, 2016. Income taxes for the three months ended February 28, 2015 included $3.8 million of discrete tax benefits. Of that amount, $1.8 million related to the reversal of unrecognized tax benefits and interest associated with a statute of limitation expiration in an international jurisdiction and the remainder principally related to the recognition of a 2014 research tax credit. A new law was enacted in the first quarter 2015 that retroactively granted the credit for our tax year 2014. Other than the $1.8 million reversal previously described and additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the three months ended February 28, 2015. As of February 29, 2016, we believe that the reasonably possible total amount of unrecognized tax benefits that could decrease in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlement would not be material.
