Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s effective tax rate for the three months ended June 25, 2016 and June 27, 2015 was 34.6% and 18.4%, respectively. The Company’s effective tax rate was 31.0% and 12.4% for each of the six months ended June 25, 2016 and June 27, 2015, respectively. For the three months ended June 25, 2016, the increase was primarily attributable to nondeductible transaction costs associated with the acquisition of WIL Research, the accrual of withholding taxes in order to access cash from the Company’s Canadian and Chinese operations for use outside of the U.S., and a prior year non-taxable bargain purchase gain of $9.9 million associated with the acquisition of Sunrise. For the six months ended June 25, 2016, the increase reflects the items above as well as a prior year reduction in unrecognized tax benefits and related interest of $10.4 million due to the expiration of the statute of limitations associated with pre-acquisition tax positions on forgiveness of debt. During the three months ended June 25, 2016, the Company’s unrecognized tax benefits increased by $1.9 million to $25.3 million, primarily due to pre-acquisition tax positions taken by WIL Research, as well as an additional quarter of Canadian Scientific Research and Experimental Development credit reserves offset by positive foreign exchange movement. The amount of unrecognized income tax benefits that would impact the effective tax rate increased by $2.1 million to $22.2 million. The amount of accrued interest on unrecognized tax benefits was $1.4 million at June 25, 2016. The Company estimates that it is reasonably possible that the unrecognized tax benefits will decrease by up to $3.0 million over the next twelve-month period, primarily as a result of the outcome of a pending tax ruling and competent authority ruling. The Company conducts business in a number of tax jurisdictions. As a result, it is subject to tax audits in jurisdictions including the U.S., U.K., China, Japan, France, Germany and Canada. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2012. The Company and certain of its subsidiaries have ongoing tax controversies with various tax authorities in the U.S., Canada, China and France. The Company does not believe that resolution of these controversies will have a material impact on its financial position or results of operations. In accordance with the Company’s policy, the remaining undistributed earnings of its non-U.S. subsidiaries remain indefinitely reinvested as of the end of the three months ended June 25, 2016 as they are required to fund needs outside the U.S. and cannot be repatriated in a manner that is substantially tax free. Income tax expense related to change in unrecognized pension gains, losses and prior service costs was $0.1 million and $0.3 million for the three months ended June 25, 2016 and June 27, 2015, respectively. Income tax expense related to change in unrecognized pension gains, losses, and prior service costs was $0.3 million and $0.5 million for the six months ended June 25, 2016 and June 27, 2015, respectively.
