Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has provided income taxes for the six month periods ended June 28, 2014 and June 29, 2013, based on its estimate of the effective tax rate for the entire 2014 and 2013 fiscal years. For fiscal 2014, the Company’s effective tax rate is significantly affected by the VION Acquisition including non-deductible acquisition costs, Subpart F income and entities that are subject to income tax at various tax rates in their countries of operation that differ from the U.S. statutory tax rate. The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company’s net deferred tax liability increased by approximately $326.0 million in the six month period ended June 28, 2014 principally due to deferred tax liabilities acquired in the stock acquisition resulting in carryover tax basis in the VION Acquisition including the accumulated earnings of certain foreign joint ventures. The Company expects to indefinitely reinvest the earnings of its foreign subsidiaries outside of the United States and has generally not provided deferred income taxes on the accumulated earnings of its foreign subsidiaries. The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends and its outlook for future years. Certain VION Companies acquired as part of the VION Acquisition have deferred tax assets for tax loss carryforwards, and the Company has recorded valuation allowances in respect to those losses in the purchase accounting for the acquisition to the extent it has been determined that it is not more likely than not that the deferred tax assets will be realized. Unrecognized tax benefits represent the difference between tax positions taken or expected to be taken in a tax return and the benefits recognized for financial statement purposes. The Company’s uncertain tax positions increased by $5.9 million during the six month period ended June 28, 2014 primarily related to the recording of positions from the VION Acquisition in purchase accounting. At June 28, 2014, the Company had $4.6 million of gross unrecognized tax benefits and $2.0 million of related accrued interest and penalties. It is reasonably possible within the next twelve months that the Company’s gross unrecognized tax benefits may decrease by up to $2.1 million, excluding interest and penalties, primarily due to potential settlements and expiration of certain statutes of limitations. The Company’s major taxing jurisdictions include the United States (federal and state), Canada, the Netherlands, Belgium, Brazil, Germany, France and China. The Company is subject to regular examination by various tax authorities and although the final outcome of these examinations is not yet determinable, the Company does not anticipate that any of the examinations will have a significant impact on the Company's results of operations or financial position. The statute of limitations for the Company’s major tax jurisdictions is open for varying periods, but is generally closed through the 2005 tax year.

Income Taxes

The Company has provided income taxes for the six month periods ended June 28, 2014 and June 29, 2013, based on its estimate of the effective tax rate for the entire 2014 and 2013 fiscal years.

The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.
