Income Tax Disclosure [Abstract]
Income Tax	Income Tax Our effective tax rates for the third quarters of 2012 and 2011 were approximately 17% and 14%, respectively. For the first three quarters of 2012 and 2011, our effective tax rates were approximately 18% and 15%, respectively. Our effective tax rate estimate for the full year is based on the preliminary purchase accounting for the Acquisition, which was updated in the third quarter of 2012, and may be adjusted as purchase accounting is finalized. Our tax rate is volatile and may move up or down with changes in, among other things, the amount and source of income or loss, our ability to utilize foreign tax credits, changes in tax laws, and the movement of liabilities established for uncertain tax positions as statutes of limitations expire or positions are otherwise effectively settled. There are proposed or pending tax law changes in various jurisdictions that, if enacted, may have an impact on our effective tax rate. As of December 31, 2011, we had Unrecognized tax benefits including interest, penalties and offsetting positions of $77.4 million, of which $1.0 million was current and included in Accrued expenses and other liabilities and $76.4 million was non-current. As of September 29, 2012, Unrecognized tax benefits increased by $21.4 million from December 31, 2011. This addition is net of varying items including increases and decreases due to fluctuations in foreign exchange rates, additional uncertain tax benefits, including those from the Acquisition, interest accrued for the current year, certain tax positions closing or being effectively settled, and payments made to tax authorities with regard to uncertain tax benefits during the first three quarters of 2012. This results in Unrecognized tax benefits including interest, penalties and offsetting positions of $98.8 million as of September 29, 2012, of which $3.0 million is current and included in Accrued expenses and other liabilities and $95.8 million is non-current. During the remainder of 2012, we expect to recognize approximately $9.0 million of non-cash income tax benefit due primarily to the favorable resolution of unrecognized tax positions that we effectively settled early in the fourth quarter of 2012. We file income tax returns in most of the federal, state, and provincial jurisdictions in the U.S., Canada, the U.K., and various countries in Central Europe. Tax years through 2006 are closed in the U.S., while exam years 2007 and 2008 have been effectively settled and only remain open pending finalization of an advanced pricing agreement. Tax years through fiscal year ended 2006 are closed or have been effectively settled through examination in Canada. Tax year 2007 is currently under audit in Canada. The audit is closed for all issues except one relating to an intercompany transaction. Tax years through 2008 are closed or have been effectively settled through examination in the U.K. Tax years through fiscal year 2004 are closed for most countries in Central European jurisdictions with statutes of limitations varying from 3-7 years.
