Income Tax Disclosure [Abstract]
Income Tax	Income Taxes The Company accounts for income taxes under the provisions of ASC 740, Accounting for Income Taxes. The Company's effective tax rate of approximately 54% for the three month period ended March 31, 2012 is based on the Company's estimated annual effective tax rate of approximately 47% adjusted for discrete items of $(0.1) million in the period. The Company's income tax provisions for the three month periods ended March 31, 2012 and April 2, 2011 were $2.0 million and $5.7 million, respectively. The effective income tax rate for the three month period ended March 31, 2012 exceeded the statutory U.S. federal income tax rate of 35% primarily due to state income taxes and foreign losses for which no current benefit is available, offset by the domestic manufacturing deduction benefit. The effective income tax rate for the three month period ended April 2, 2011 was substantially equivalent to the statutory U.S. federal income tax rate of 35% primarily due to state income taxes expense offset by the domestic manufacturing deduction benefit. As of March 31, 2012 the Company continued to maintain a valuation allowance against certain net deferred tax assets as a result of uncertainties regarding the realization of the asset balance due to cumulative losses and uncertainty of future taxable income in various tax jurisdictions. In the event that the Company determines that the deferred tax assets are realizable, an adjustment to the valuation allowance will be reflected in the tax provision for the period such determination is made. The Company is subject to taxation in the United States and various states including California, and foreign jurisdictions including South Korea, Japan, China, Germany, France and the United Kingdom. Due to tax attribute carry-forwards, the Company is subject to examination by the Internal Revenue Service for tax years beginning from the 2003 tax year for U.S. tax purposes. The Company is also subject to examination in various states for tax years beginning from the 2002 tax year. The Company is also subject to examination in various foreign jurisdictions beginning from the 2006 tax year. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. The total amount of accrued penalties and interest is not material for the three month period ended March 31, 2012. The Company believes it may recognize up to $0.2 million of its existing unrecognized tax benefits within the next twelve months as a result of the lapse of the applicable statutes of limitations.
