Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate for the first quarter of 2015 was 28.4 percent, compared with 26.2 percent for the comparable 2014 period. The higher 2015 rate was due to higher 2015 first quarter losses incurred related to the devaluation of the Venezuelan bolivar for which no tax benefit can be recognized. The effective tax rates are below the U.S. statutory rate primarily due to lower foreign effective tax rates. As of March 28, 2015 and December 27, 2014, the Company's gross unrecognized tax benefit was $20.2 million and $22.5 million, respectively. The Company estimates that approximately $18.2 million of the unrecognized tax benefits, if recognized, would impact the effective tax rate. Interest and penalties related to uncertain tax positions in the Company's global operations are recorded as a component of the provision for income taxes. Accrued interest and penalties were $4.9 million and $6.5 million as of March 28, 2015 and December 27, 2014, respectively. During 2015, the accrual for uncertain tax positions decreased by $2.3 million primarily as a result of the Company agreeing to audit settlements with various jurisdictions, $1.3 million of which reduced the accrual for interest and penalties. The accrual for uncertain tax positions also increased for positions being taken in various global tax filings, and decreased due to the impact of foreign currency fluctuations. The Company estimates that it may settle one or more foreign audits in the next twelve months that may result in a decrease in the amount of accrual for uncertain tax positions of up to $1.0 million.

While the Company does not currently expect material changes, it is possible that the amount of unrecognized benefit with respect to the uncertain tax positions will significantly increase or decrease related to audits in various foreign jurisdictions that may conclude during that period or new developments that could also, in turn, impact the Company's assessment relative to the establishment of valuation allowances against certain existing deferred tax assets. These valuation allowances relate to tax assets in jurisdictions where it is management's best estimate that there is not a greater than 50 percent probability that the benefit of the assets will be realized in the associated tax returns. The likelihood of realizing the benefit of deferred tax assets is assessed on an ongoing basis. This assessment requires estimates as to future operating results, as well as an evaluation of the effectiveness of the Company's tax planning strategies.
