Income Tax Disclosure [Abstract]
Income Taxes	Note 10 — Income Taxes The Company recorded income tax provisions of $5.2 million and $2.9 million for the three and six months ended June 30, 2013, respectively, and an income tax provision of $11.8 million and an income tax benefit of $37.3 million for the three and six months ended July 1, 2012, respectively. The income tax provision for the six months ended June 30, 2013 included a reversal of $8.7 million of liabilities for uncertain tax positions, which included previously unrecognized tax benefits of $3.9 million and interest and penalties of $4.8 million, as a result of the expiration of statutes of limitations in multiple jurisdictions. The income tax benefit for the six months ended July 1, 2012 included a tax benefit of approximately $43.2 million due to the release of valuation allowance resulting from the net deferred tax liabilities recorded as part of the SandForce purchase price allocation. The income tax benefit for the six months ended July 1, 2012 also included a reversal of $10.2 million of liabilities for uncertain tax positions, which included previously unrecognized tax benefits of $5.2 million and interest and penalties of $5.0 million, as a result of the expiration of statutes of limitations in multiple jurisdictions. The Company computes its tax provision using an estimated annual tax rate. The Company excludes certain loss jurisdictions from the computation of the estimated annual rate when no benefit can be realized on those losses. Historically, the Company has sustained losses from its U.S. operations and, as a result, has maintained a full valuation allowance against U.S. net deferred tax assets. The Company recently achieved profitability in the U.S., however, management does not believe there is sufficient positive evidence to reach a conclusion that it is more likely than not that the Company will generate sufficient future taxable income in the U.S. to realize the benefits of its deferred tax assets. Depending on future results and projected trends, it is reasonably possible that Company may determine in the foreseeable future that it is more likely than not that a significant portion of its U.S. deferred tax assets will be realized, resulting in a release of a significant portion of the valuation allowance. As of June 30, 2013, the Company had $200.1 million of unrecognized tax benefits, for which the Company is unable to make a reasonably reliable estimate as to when cash settlement with a taxing authority may occur. It is reasonably possible that the total amount of unrecognized tax benefits will increase or decrease in the next 12 months. Such changes could occur based on the normal expiration of statutes of limitations, the possible conclusion of ongoing tax audits in various jurisdictions around the world or other negotiations with tax authorities.
