Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES During the three and nine months ended August 31, 2014, we reversed previously provided reserves for uncertain tax benefits and related interest of $0.8 million, principally as a result of statute of limitation expirations. Additionally, during the nine months ended August 31, 2014, we reached a settlement with respect to the French taxing authority’s audits of the 2007-2013 tax years. In connection with that settlement, we 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 reversals, there were no significant changes to unrecognized tax benefits during the three and nine months ended August 31, 2014. Income tax expense for the three months ended August 31, 2014 included discrete tax benefits of $6.2 million. The principal components of those discrete tax benefits recognized in the third quarter of 2014 included the following: (i) the reversal of previously provided reserves for uncertain tax benefits and related interest in the amount of $0.8 million, described above; (ii) the reversal of international tax expense in the amount of $3.7 million related to fiscal 2013, recorded earlier in 2014 as a result of a retroactive change in French tax law enacted in the first quarter of 2014 (during the third quarter of 2014, final legislative guidance on that French tax law change was issued, which resulted in our reversal of previously provided expense); and (iii) a $1.4 million benefit as a result of the adjustment of prior year tax accruals upon completion of the related tax returns. Income tax expense for the nine months ended August 31, 2014 included discrete tax benefits of $5.5 million. In addition to the $6.6 million aggregate tax benefit recognized in the first nine months of 2014 associated with the reversal of previously provided reserves for uncertain tax benefits and related interest, described in the initial paragraph of this Note 8, the following represent the significant discrete tax items recognized in the first nine months of 2014: (i) international tax expense of $2.2 million related to prior year adjustments agreed as part of the French tax settlement previously described; and (ii) a $1.4 million benefit as a result of the adjustment of prior year tax accruals upon completion of the related tax returns. There were $3.3 million of discrete tax benefits in the quarter ended August 31, 2013. These discrete tax benefits were mainly due to the reversal of a valuation allowance originally established against a subsidiary’s net operating losses. This subsidiary established a pattern of profitability which resulted in us concluding during the third quarter of 2013 that the valuation allowance should be reversed. Income taxes for the nine months ended August 31, 2013 included a total of $4.5 million of discrete tax benefits due to the third quarter item noted above and the recognition of a 2012 U.S. research tax credit, which was recorded in the first quarter of 2013. A new law was enacted in the first quarter of 2013 that retroactively granted the credit for 2012. In 2010, the Internal Revenue Service (IRS) commenced an examination of our U.S. federal income tax return for the 2007 and 2008 tax years. During the course of the examination, we have held discussions with the IRS on certain issues and, in October 2012, we received proposed adjustments for these tax years. In November 2012, we deposited $18.8 million with the IRS to stop any potential interest on these proposed adjustments. We disagree with certain of the proposed adjustments and, in December 2012, we filed a protest to initiate the IRS administrative appeals process. During 2014, the appeals process continued, with meetings and submission of supplemental materials. We believe that we have established appropriate tax accruals under U.S. GAAP for these issues.
