Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For each interim reporting period, the company makes an estimate of the effective tax rate expected to be applicable for the full fiscal year pursuant to FASB ASC Topic 740-270, “Accounting for Income Taxes in Interim Periods.” The rate so determined is used in providing for income taxes on a year-to-date basis. Jurisdictions with a projected loss for the year or an actual year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. Income tax expense (benefit) is allocated between continuing operations, discontinued operations and other comprehensive income (OCI). Such allocation is applied by tax jurisdiction, and in periods in which there is a pre-tax loss from continuing operations and pre-tax income in another category, such as discontinued operations or OCI, income tax expense is allocated to the other sources of income, with a related benefit recorded in continuing operations. For the first six months of fiscal year 2015, the company had approximately $36 million of net pre-tax income compared to a net pre-tax loss of $34 million in the first six months of fiscal year 2014 in tax jurisdictions in which tax expense (benefit) is not recorded. Income or losses arising from these jurisdictions resulted in an adjustment to the valuation allowance, rather than an adjustment to income tax expense. If, in the future, the company is generating taxable income on a sustained basis in jurisdictions where it has recorded valuation allowances, the company's conclusion regarding the need for valuation allowances in these jurisdictions could change. This would result in a reversal of some or all of the valuation allowances.

For each interim reporting period, the company makes an estimate of the effective tax rate expected to be applicable for the full fiscal year pursuant to FASB ASC Topic 740-270, “Accounting for Income Taxes in Interim Periods.” The rate so determined is used in providing for income taxes on a year-to-date basis. Jurisdictions with a projected loss for the year or an actual year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.

Income tax expense (benefit) is allocated between continuing operations, discontinued operations and other comprehensive income (OCI). Such allocation is applied by tax jurisdiction, and in periods in which there is a pre-tax loss from continuing operations and pre-tax income in another category, such as discontinued operations or OCI, income tax expense is allocated to the other sources of income, with a related benefit recorded in continuing operations.

For the first six months of fiscal year 2015, the company had approximately $36 million of net pre-tax income compared to a net pre-tax loss of $34 million in the first six months of fiscal year 2014 in tax jurisdictions in which tax expense (benefit) is not recorded.
