Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES 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. We believe that it is reasonably possible that the total amount of unrecognized tax benefits as of February 28, 2015 could decrease by approximately $7.0 million in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlements. During the three months ended February 28, 2014, the Company reached a settlement with respect to the French taxing authority’s audits of the 2007-2011 tax years. In connection with that settlement, the Company recognized international tax expense of $2.2 million related to adjustments agreed as part of the settlement and a tax benefit of $5.8 million associated with the reversal of unrecognized tax benefits and interest related to the settlement. Income taxes for the three months ended February 28, 2014, included the following discrete tax items in addition to those associated with the French tax settlement: (i) international tax expense of $0.6 million related to an increased valuation allowance associated with prior year losses of a non-U.S. subsidiary due to a change in our assessment of the likely realization of such losses; and (ii) international tax expense of $3.7 million related to fiscal year 2013 arising from a retroactive change in French tax law enacted in the three months ended February 28, 2014. (Later in 2014, final legislative guidance on that French tax law change was issued, which resulted in our reversal, during the third quarter of 2014, of the $3.7 million of tax expense that was provided in the first quarter of 2014.)

INCOME TAXES

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. We believe that it is reasonably possible that the total amount of unrecognized tax benefits as of February 28, 2015 could decrease by approximately $7.0 million in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlements.

During the three months ended February 28, 2014, the Company reached a settlement with respect to the French taxing authority’s audits of the 2007-2011 tax years. In connection with that settlement, the Company recognized international tax expense of $2.2 million related to adjustments agreed as part of the settlement and a tax benefit of $5.8 million associated with the reversal of unrecognized tax benefits and interest related to the settlement. Income taxes for the three months ended February 28, 2014, included the following discrete tax items in addition to those associated with the French tax settlement: (i) international tax expense of $0.6 million related to an increased valuation allowance associated with prior year losses of a non-U.S. subsidiary due to a change in our assessment of the likely realization of such losses; and (ii) international tax expense of $3.7 million related to fiscal year 2013 arising from a retroactive change in French tax law enacted in the three months ended February 28, 2014.
