Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate The Company's effective tax rate, which is calculated by dividing each fiscal period's provision for income taxes by pretax income, was 27.1% and 27.8% during the three-month periods ended September 26, 2015 and September 27, 2014, respectively, and 27.6% and 29.3% during the six-month periods ended September 26, 2015 and September 27, 2014, respectively. The effective tax rates in the periods presented were lower than the U.S. federal statutory income tax rate of 35% principally as a result of the proportion of earnings generated in lower taxed foreign jurisdictions versus the U.S. In addition, the effective tax rate for the six months ended September 26, 2015 was favorably impacted by the reversal of certain tax liabilities due to the expiration of statutes of limitations and a change in estimate related to the assessment period of certain tax liabilities. The effective tax rate for the six months ended September 27, 2014 was also favorably impacted from the legal entity restructuring of certain of the Company’s foreign operations during Fiscal 2015, partially offset by additional tax reserves associated with the conclusion of tax examinations. During the three months ended September 26, 2015, the Company concluded, with the assistance of a third-party consultant, that based on recent audit settlements and taxpayer audit trends, the assessment period associated with certain tax liabilities established under ASC Topic 740, "Income Taxes," should be reduced. This change is considered a change in estimate for accounting purposes and is reflected in the current period. This change lowered the Company's provision for income taxes by $8 million, including interest and penalties, and net of deferred tax asset reversals, and increased basic and diluted earnings per share by $0.09 for each of the three-month and six-month periods ended September 26, 2015. Uncertain Income Tax Benefits The Company classifies interest and penalties related to unrecognized tax benefits as part of its provision for income taxes. The total amount of unrecognized tax benefits, including interest and penalties, was $90 million and $116 million as of September 26, 2015 and March 28, 2015, respectively, and is included within non-current liability for unrecognized tax benefits in the consolidated balance sheets. The reduction in unrecognized tax benefits, including interest and penalties, primarily related to the reversal of tax liabilities of $11 million and $9 million due to the change in estimate previously discussed and the expiration of statutes of limitations, respectively, as well as tax audit settlements of $8 million, partially offset by additional tax liabilities largely associated with the conclusion of a tax examination. The total amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate was $66 million and $85 million as of September 26, 2015 and March 28, 2015, respectively. Future Changes in Unrecognized Tax Benefits The total amount of unrecognized tax benefits relating to the Company's tax positions is subject to change based on future events including, but not limited to, settlements of ongoing tax audits and assessments and the expiration of applicable statutes of limitations. Although the outcomes and timing of such events are highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits, excluding interest and penalties, could potentially be reduced by approximately $11 million during the next 12 months. However, changes in the occurrence, expected outcomes, and timing of such events could cause the Company's current estimate to change materially in the future. The Company files a consolidated U.S. federal income tax return, as well as tax returns in various state, local, and foreign jurisdictions. The Company is generally no longer subject to examinations by the relevant tax authorities for years prior to its fiscal year ended March 31, 2007.
