Income Taxes	6 Months Ended
May. 31, 2015
Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES Income taxes for the three months ended May 31, 2015, included $13.4 million of discrete tax benefits, consisting principally of the following: (i) a reversal of a previously established valuation allowance on a foreign deferred tax asset in the amount of $8.6 million due to a change in facts that favorably impacted our assessment of the likely recoverability of that deferred tax asset; and (ii) the reversals of unrecognized tax benefits and related interest in the amount of $5.0 million associated with expirations of statutes of limitations in the U.S. and international jurisdictions. Income taxes for the six months ended May 31, 2015, included $17.2 million of discrete tax benefits, consisting of the amounts described above as well as an additional $3.8 million of discrete tax benefits of which $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 2014 tax year. Other than the reversals previously described and additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the three months and six months ended May 31, 2015. During the six months ended May 31, 2014, the Company reached a settlement with respect to the French taxing authority’s audits of the 2007-2013 tax years. In connection with that settlement, the Company reversed previously provided reserves for uncertain tax benefits and related interest of $5.8 million in the first quarter of 2014. Other than additions for current year tax positions and for the previously described reversal, there were no significant changes to unrecognized tax benefits during the three and six months ended May 31, 2014. Income taxes for the six months ended May 31, 2014 included the following additional discrete tax items: (i) international tax expense of $2.2 million related to prior year adjustments agreed as part of the French tax settlement previously described; (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 first quarter; and (iii) international tax expense of $0.6 million relating 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. (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.) There were no discrete tax items recognized in the quarter ended May 31, 2014. As of May 31, 2015, we believe that the reasonably possible total amount of unrecognized tax benefits that could change in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlement would not result in a change to unrecognized tax benefits that is material to our consolidated financial results.

INCOME TAXES

Income taxes for the three months ended May 31, 2015, included $13.4 million of discrete tax benefits, consisting principally of the following: (i) a reversal of a previously established valuation allowance on a foreign deferred tax asset in the amount of $8.6 million due to a change in facts that favorably impacted our assessment of the likely recoverability of that deferred tax asset; and (ii) the reversals of unrecognized tax benefits and related interest in the amount of $5.0 million associated with expirations of statutes of limitations in the U.S. and international jurisdictions. Income taxes for the six months ended May 31, 2015, included $17.2 million of discrete tax benefits, consisting of the amounts described above as well as an additional $3.8 million of discrete tax benefits of which $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 2014 tax year. Other than the reversals previously described and additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the three months and six months ended May 31, 2015.

During the six months ended May 31, 2014, the Company reached a settlement with respect to the French taxing authority’s audits of the 2007-2013 tax years. In connection with that settlement, the Company reversed previously provided reserves for uncertain tax benefits and related interest of $5.8 million in the first quarter of 2014. Other than additions for current year tax positions and for the previously described reversal, there were no significant changes to unrecognized tax benefits during the three and six months ended May 31, 2014.

Income taxes for the six months ended May 31, 2014 included the following additional discrete tax items: (i) international tax expense of $2.2 million related to prior year adjustments agreed as part of the French tax settlement previously described; (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 first quarter; and (iii) international tax expense of $0.6 million relating 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. (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.)

There were no discrete tax items recognized in the quarter ended May 31, 2014.

As of May 31, 2015, we believe that the reasonably possible total amount of unrecognized tax benefits that could change in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlement would not result in a change to unrecognized tax benefits that is material to our consolidated financial results.
