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, 2013. 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 the third quarter of 2012, we repatriated $70.0 million of cash from foreign subsidiaries. This transaction generated U.S. foreign tax credits due to the mix of foreign earnings that related to this cash and reduced 2012 third quarter tax expense by $5.6 million. Income taxes for the nine months ended August 31, 2012 were impacted by these U.S. foreign tax credits 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 established a pattern of profitability which resulted in us concluding during the second quarter of 2012 that a portion of the valuation allowance should be reversed.
