Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes The Company’s income tax provision for both the three months ended October 3, 2014 and September 27, 2013 was $37 million. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia, the Philippines, Singapore and Thailand that expire at various dates from 2015 through 2025 and the current year generation of income tax credits. In the three months ended October 3, 2014, the Company recorded a net increase of $7 million in its liability for unrecognized tax benefits. As of October 3, 2014, the Company's liability for unrecognized tax benefits was approximately $307 million. Interest and penalties recognized on such amounts were not material to the condensed consolidated financial statements during the three months ended October 3, 2014. The Internal Revenue Service (“IRS”) previously completed its field examination of the Company’s federal income tax returns for fiscal years 2006 and 2007, and the Company and the IRS reached agreement with respect to all matters except on the proposed adjustments to income before income taxes relating to intercompany payable balances. The proposed adjustments relating to intercompany payable balances for fiscal years 2006 and 2007 will be addressed in conjunction with the IRS’s examination of the Company’s fiscal years 2008 and 2009, which commenced in January 2012. In addition, in January 2012, the IRS commenced an examination of the 2007 fiscal period ended September 5, 2007 of Komag, Incorporated, which was acquired by the Company on September 5, 2007. The Company anticipates that the IRS fieldwork will be completed in the fourth quarter of fiscal year 2015. With respect to the 2008 and 2009 audit, the Company received a notice of proposed adjustment from the IRS relating to intercompany payable balances. The proposed adjustments to income before income taxes relating to intercompany payable balances for fiscal years 2006, 2007, 2008 and 2009 total approximately $200 million. The Company disagrees with the proposed adjustments, believes that its tax position is properly supported and will vigorously contest the position taken by the IRS. The IRS examined calendar years 2010 and 2011 of HGST, which was acquired by the Company on March 8, 2012, and completed the examination with no material adjustments. The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of October 3, 2014, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns.
