Income Taxes	9 Months Ended
Feb. 28, 2013
Income Taxes	NOTE 12 — INCOME TAXES The effective income tax rate was 29.8% for the three months ended February 28, 2013 compared to an effective income tax rate of 30.7% for the three months ended February 29, 2012. The effective income tax rate was 48.0% for the nine months ended February 28, 2013 compared to an effective income tax rate of 29.6% for the same period a year ago. For the three and nine months ended February 28, 2013 and February 29, 2012, respectively, the effective tax rate was reduced below the federal statutory rate due to lower effective tax rates of certain of our foreign subsidiaries, the favorable impact of certain foreign operations on our U.S. taxes, the research and development tax credit, and due to the benefit of the domestic manufacturing deduction. Additionally, for the nine months ended February 28, 2013 and February 29, 2012, decreases in the effective income tax rate resulted from a reduction in the United Kingdom income tax rate. Further, the effective income tax rate for the nine months ended February 29, 2012 decreased due to net reductions to our reserves for income tax contingencies, including interest thereon. For the three and nine months ended February 28, 2013 and February 29, 2012, respectively, the effective tax rate increased principally as a result of the impact of valuation allowances associated with U.S. foreign tax credit carryforwards and certain foreign net operating losses, state and local income taxes, and non-deductible business operating expenses. Furthermore, for the three and nine month periods ended February 28, 2013, the effective tax rate differed from the federal statutory rate as a result of income tax benefits related to our strategic decision to reposition certain Brazilian business operations, the impact on our effective tax rate in certain foreign jurisdictions where income tax benefits associated with net operating losses incurred by those foreign businesses are not recognized, the tax effect of projected non-deductible costs associated with the DOJ and GSA accrual and due to net increases to our reserves for income tax contingencies, including interest thereon. Additionally, for the nine months ended February 28, 2013 the effective tax rate differed from the federal statutory rate as a result of increases in valuation allowances related to losses associated with our investments in Kemrock. As of February 28, 2013, we had unrecognized tax benefits of approximately $8.8 million, of which approximately $8.0 million would impact the effective tax rate, if recognized. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. At February 28, 2013 the accrual for interest and penalties was $5.5 million. Unrecognized tax benefits, including interest and penalties, have been classified as other long-term liabilities unless expected to be paid in one year. We classified approximately $2.2 million of our reserve for uncertain tax positions, which includes associated interest and penalties, as a current liability as this amount could be reversed during the next 12 months. We do not anticipate any other significant changes to the total unrecognized tax benefits within the next 12 months. We, or our subsidiaries, file income tax returns in the U.S. and in various state, local and foreign jurisdictions. As of February 28, 2013 we are subject to U.S. federal income tax examinations for the fiscal years 2011 through 2012. In addition, with limited exceptions, we, or our subsidiaries, are generally subject to state and local or non-U.S. income tax examinations by tax authorities for the fiscal years 2006 through 2012. We are currently under examination, or have been notified of an upcoming tax examination for various Non-U.S. and U.S. jurisdictions including an ongoing Internal Revenue Service (“IRS”) examination of the company’s U.S. income tax return for the fiscal 2011 tax year. Although it is possible that certain tax examinations could be resolved during the next 12 months, the timing and outcomes are uncertain. During the third quarter of fiscal 2013 we settled the IRS examination of the company’s U.S. income tax returns for the fiscal 2009 and 2010 tax years resulting in a net refund. The IRS adjustments related to, amongst other items, the deductibility of certain of our expenditures, exclusion of selective items of miscellaneous income and our research tax credit positions. The settlement did not have a material impact on our financial statements. As of February 28, 2013, we have determined, based on the available evidence, that it is uncertain whether we will be able to recognize certain deferred tax assets. Therefore, we intend to maintain the tax valuation allowances recorded at February 28, 2013 for those deferred tax assets until sufficient positive evidence (for example, cumulative positive foreign earnings or additional foreign source income) exists to support their reversal. These valuation allowances relate to U.S. foreign tax credit carryforwards, U.S. capital loss carryforwards, certain foreign net operating losses and net foreign deferred tax assets. A portion of the valuation allowance is associated with deferred tax assets recorded in purchase accounting for prior year acquisitions. We include SPHC and its domestic subsidiaries (collectively, the “SPHC Group”) in our consolidated federal income tax return. We entered into a tax-cooperation agreement (the “Agreement”) with the SPHC Group, effective from June 1, 2010. Generally, the Agreement provides, amongst other items, that the federal income taxes of the SPHC Group are to be computed on a stand-alone separate return basis. The current portion of such income tax payable, if any, is due from the SPHC Group to us. Conversely, subject to the terms of the Agreement, income tax benefits associated with net operating loss or tax credit carryovers generated by the SPHC Group, if any, for the taxable year that benefits our consolidated income tax return for that taxable year are payable by us to the SPHC Group. Additionally, pursuant to the terms of the Agreement, a similar approach is applied to consolidated, combined or unitary state tax returns.
