Income Tax Disclosure [Abstract]
Income tax disclosure	INCOME TAXES Other than additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the nine months ended August 31, 2012. In the third quarter of 2012, we repatriated $70.0 million of cash from foreign subsidiaries. This transaction will generate U.S. foreign tax credits due to the mix of foreign earnings that related to this cash. These U.S. foreign tax credits will reduce 2012 tax expense by approximately $8.9 million and reduced third quarter tax expense by $5.6 million. Income taxes for the three months ended August 31, 2012 were impacted by the U.S. foreign tax credits described above and there were no discrete tax effects in the quarter. Income taxes for the nine months ended August 31, 2012 were impacted by the U.S. foreign tax credits described above and also by $1.4 million of discrete tax benefits. These discrete tax benefits were mainly due to the reversal of a portion of a valuation allowance originally established against a subsidiary’s net operating losses. This subsidiary has established a pattern of profitability which resulted in us concluding during the quarter that a portion of the valuation allowance should be reversed. The effective tax rate for the three months and nine months ended August 31, 2011 includes $3.7 million and $4.5 million, respectively, in discrete tax benefits. These favorable effects include the adjustment of an estimate used in a prior year tax provision after the actual tax return was filed and the reversal of certain tax accruals based on new facts related to a prior year tax provision. 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 June 2012 we received Notices of Proposed Adjustments (NOPAs) for these tax years. We believe we have established appropriate deferred taxes or tax accruals under US GAAP for these issues in prior periods. While it is often difficult to predict the final outcome or the timing of resolution of uncertain tax positions, we believe that our unrecognized tax benefits reflect the most likely outcome. We will continue to update these unrecognized tax benefits, and the related interest, in light of changing facts and circumstances in the future.

INCOME TAXES

Other than additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the nine months ended August 31, 2012.

In the third quarter of 2012, we repatriated $70.0 million of cash from foreign subsidiaries. This transaction will generate U.S. foreign tax credits due to the mix of foreign earnings that related to this cash. These U.S. foreign tax credits will reduce 2012 tax expense by approximately $8.9 million and reduced third quarter tax expense by $5.6 million.

Income taxes for the three months ended August 31, 2012 were impacted by the U.S. foreign tax credits described above and there were no discrete tax effects in the quarter. Income taxes for the nine months ended August 31, 2012 were impacted by the U.S. foreign tax credits described above and also by $1.4 million of discrete tax benefits.
