Income Taxes	Income Taxes Cooper’s effective tax rate (ETR) (provision for income taxes divided by pretax income) for the fiscal first nine months of 2012 was 8.5%. Our year-to-date results include the projected fiscal year ETR, plus any discrete items. The ETR used to record the provision for income taxes for the fiscal first nine months of 2011 was 8.5%. The ETR is below the United States statutory rate as a majority of our income is earned in foreign jurisdictions with lower tax rates. We recognize the benefit from a tax position only if it is more likely than not that the position would be sustained upon audit based solely on the technical merits of the tax position. As of November 1, 2011, the Company had total gross unrecognized tax benefits of $27.4 million. If recognized, $27.3 million of unrecognized tax benefits would impact the Company’s ETR. For the nine-month period ended July 31, 2012, there were no material changes to the total amount of unrecognized tax benefits. Interest and penalties of $1.6 million have been reflected as a component of the total liability as of November 1, 2011. It is the Company’s policy to recognize the items of interest and penalties directly related to income taxes as additional income tax expense. Included in the balance of unrecognized tax benefits at November 1, 2011, is $9.0 million related to tax positions for which it is reasonably possible that the total amounts could significantly change during the next twelve months. This amount represents a decrease in unrecognized tax benefits related to the settlement of litigation in the U.S. Tax Court and expiring statutes in various jurisdictions worldwide and is comprised of transfer pricing, Subpart F and other items. As of July 31, 2012, the tax years for which the Company remains subject to United States Federal income tax assessment upon examination are 2008 through 2011. The Company remains subject to income tax examinations in other major tax jurisdictions including the United Kingdom, France and Australia for the tax years 2007 through 2011. On April 1, 2011, the Internal Revenue Service (IRS) issued a Notice of Deficiency to the Company in connection with its audit of the Company’s income tax returns for the years 2005 and 2006. The Notice asserted that the Company is subject to additional taxes due for its tax year 2005 under the anti-deferral provisions of Subpart F of the Internal Revenue Code. A settlement concerning the 2005 claimed deficiency was subsequently reached with District Counsel for the IRS which effectively settled all related matters. The decision document was filed with the U.S. Tax Court on January 19, 2012, with an agreed net deficiency of about $50 thousand.
