Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	3. Income Taxes The provision for income taxes for all periods presented is based on an estimated effective income tax rate for the respective full fiscal years. The estimated annual effective income tax rate is determined excluding the effect of significant discrete items or items that are reported net of their related tax effects. The tax effect of significant, discrete items is reflected in the period in which they occur. The Company's income tax expense is impacted by a number of factors, including the amount of taxable earnings derived in foreign jurisdictions with tax rates that are higher or lower than the U.S. federal statutory rate, state tax rates in the jurisdictions where the Company does business and the Company's ability to utilize various tax credits and net operating loss (“NOL”) carryforwards. The effective income tax rate for the second quarter of fiscal 2012 was (4.7)% versus 33.8% in the second quarter of fiscal 2011. The income tax benefit, associated with the income before income taxes, for the second quarter of fiscal 2012 is attributable to the recognition of certain, previously unrecognized tax benefits due to the lapse of applicable statute of limitations. The effective income tax rate of 33.8% for the second quarter of fiscal 2011 includes the accrual of foreign income taxes at statutory rates that are generally below the U.S. federal statutory rate of 35.0%. The effective income tax rate for the first six months of fiscal 2012 was (20.6)% versus 32.6% in the first six months of fiscal 2011. The income tax benefit, associated with the income before income taxes, for the first six months of fiscal 2012 is due to the effect of a significant decrease in the valuation allowance for U.S. foreign tax credit carryforwards for which realization of such benefits is now deemed more-likely-than-not; as well as, recognition of certain, previously unrecognized tax benefits due to the lapse of the applicable statute of limitations. The effective income tax rate of 32.6% for the first six months of fiscal 2011 includes the accrual of foreign income taxes at statutory rates that are generally below the U.S. federal statutory rate of 35.0%. At October 1, 2011, the Company had a $24.2 million liability for unrecognized net income tax benefits. At March 31, 2011, the Company's total liability for unrecognized net income tax benefits was $26.0 million. The Company recognizes accrued interest and penalties related to unrecognized income tax benefits in income tax expense. As of October 1, 2011 and March 31, 2011, the total amount of gross, unrecognized income tax benefits includes $8.7 million and $8.8 million of accrued interest and penalties, respectively. The Company recognized $(0.2) million of net interest and penalties as income tax benefit during the six months ended October 1, 2011. The Company recognized $0.3 million of net interest and penalties as income tax expense during the six months ended October 2, 2010. The Company conducts business in multiple locations within and outside the U.S. Consequently, the Company is subject to periodic income tax examinations by domestic and foreign income tax authorities. Currently, the Company is undergoing routine, periodic income tax examinations in both domestic and foreign jurisdictions. It appears reasonably possible that the amounts of unrecognized income tax benefits could change in the next twelve months as a result of such examinations; however, any potential payments of income tax, interest and penalties are not expected to be significant to the Company's consolidated financial statements. With certain exceptions, the Company is no longer subject to U.S. federal income tax examinations for tax years ending prior to March 31, 2008, state and local income tax examinations for years ending prior to fiscal 2007 or significant foreign income tax examinations for years ending prior to fiscal 2006. With respect to the Company's U.S. federal NOL carryforward, the short tax period ended March 31, 2007 is open under statutes of limitations; whereby, the Internal Revenue Service may not adjust the income tax liability for this year, but may reduce the NOL carryforward and any other tax attribute carryforwards to future, open tax years.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
