Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	(11) INCOME TAXES We estimate our annual effective tax rate at the end of each quarterly period, and we record the tax effect of certain discrete items, which are unusual or occur infrequently, in the interim period in which they occur, including changes in judgment about deferred tax valuation allowances. In addition, jurisdictions with a projected loss for the year, jurisdictions with a year-to-date loss where no tax benefit can be recognized, and jurisdictions where we are unable to estimate an annual effective tax rate are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections. We recognize deferred tax assets and liabilities for both the expected impact of differences between the financial statement amount and the tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax losses and tax credit carry forwards. We record a valuation allowance against deferred tax assets when it is considered more likely than not that all or a portion of our deferred tax assets will not be realized. In making this determination, we are required to give significant weight to evidence that can be objectively verified. It is generally difficult to conclude that a valuation allowance is not needed when there is significant negative evidence, such as cumulative losses in recent years. Forecasts of future taxable income are considered to be less objective than past results, particularly in light of the economic environment. Therefore, cumulative losses weigh heavily in the overall assessment. Based on the assumptions and requirements noted above, we have recorded a valuation allowance against most of our U.S. deferred tax assets. In addition, we expect to provide a valuation allowance on future U.S. tax benefits until we can sustain a level of profitability or until other significant positive evidence arises that suggest that these benefits are more likely than not to be realized. The provision for income taxes reported for the three and six months ended September 30, 2014 is based on our projected annual effective tax rate for fiscal year 2015, and also includes certain discrete items recorded during the period. Our effective tax rate for the three and six months ended September 30, 2014 was a tax expense of 83.3 percent and 9.1 percent, respectively, as compared to a tax expense of 5.0 percent and 59.4 percent, respectively, for the same period of fiscal year 2014. The effective tax rate for the three and six months ended September 30, 2014 and 2013 differs from the statutory rate of 35.0 percent primarily due to the utilization of U.S. deferred tax assets which were subject to a valuation allowance and non-U.S. profits subject to a reduced or zero tax rate. The effective tax rate for the three and six months ended September 30, 2014 differs from the same period in fiscal year 2014 primarily due to differences in the pre-tax income or loss. In addition, the effective tax rate for the six months ended September 30, 2014 differs from the same period in fiscal year 2014 primarily due to a discrete expense of $14 million recorded in the six months ended September 30, 2014 for excess tax benefits from stock-based compensation deductions allocated directly to contributed capital. During the three and six months ended September 30, 2014, we recorded a net decrease of $1 million and $2 million in gross unrecognized tax benefits. The total gross unrecognized tax benefits as of September 30, 2014 is $230 million. A portion of our unrecognized tax benefits will affect our effective tax rate if they are recognized upon favorable resolution of the uncertain tax positions. As of September 30, 2014, if recognized, approximately $73 million of the unrecognized tax benefits would affect our effective tax rate and approximately $157 million would result in adjustments to deferred tax assets with corresponding adjustments to the valuation allowance. During the three months ended September 30, 2014, we recorded a net decrease of $1 million for accrued interest and penalties related to tax positions taken on our tax returns and an immaterial amount for the six months ended September 30, 2014. As of September 30, 2014, the combined amount of accrued interest and penalties related to uncertain tax positions included in income tax obligations on our Condensed Consolidated Balance Sheet was approximately $16 million. We file income tax returns in the United States, including various state and local jurisdictions. Our subsidiaries file tax returns in various foreign jurisdictions, including Canada, France, Germany, Switzerland and the United Kingdom. The IRS is currently examining our returns for fiscal years 2009 through 2011, and we remain subject to income tax examination by the IRS for fiscal years after 2011. We are also currently under income tax examination in the United Kingdom for fiscal years 2010 and 2012, in Germany for fiscal years 2008 through 2012, in Spain for fiscal years 2010 through 2013. We remain subject to income tax examination for several other jurisdictions including in Canada for fiscal years after 2005, in France for fiscal years after 2011, in Germany for fiscal years after 2012, in the United Kingdom for fiscal years 2011 and after 2012, and in Switzerland for fiscal years after 2007. The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Although potential resolution of uncertain tax positions involve multiple tax periods and jurisdictions, it is reasonably possible that a reduction of up to $8 million of unrecognized tax benefits may occur within the next 12 months, some of which, depending on the nature of the settlement or expiration of statutes of limitations, may affect the Company’s income tax provision and therefore benefit the resulting effective tax rate. The actual amount could vary significantly depending on the ultimate timing and nature of any settlements.
