INCOME TAXES	9 Months Ended
INCOME TAXES	Sep. 26, 2020
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe Company’s effective tax rates for the three months ended September 26, 2020 and September 28, 2019 were 24.1% and (0.4)%, respectively. The Company’s effective tax rates for the nine months ended September 26, 2020 and September 28, 2019 were 19.5% and 12.6%, respectively. For the three and nine months ended September 26, 2020, the increase in the effective tax rates from the prior year periods were primarily related to the recognition of $20.4 million of deferred tax assets expected to be utilized as a result of changes to the Company’s international financing structure during the three months ended September 28, 2019. Partially offsetting the increase for the nine months ended September 26, 2020 was an increased tax benefit from stock-based compensation deductions in 2020 compared to the corresponding period in 2019. For the three months ended September 26, 2020, the Company’s unrecognized tax benefits increased by $0.5 million to $18.4 million, primarily due to an additional quarter of Canadian Scientific Research and Experimental Development Credit Reserves, partially offset by audit settlements of prior period positions. For the three months ended September 26, 2020, the amount of unrecognized income tax benefits that would impact the effective tax rate increased by $0.9 million to $16.0 million for the same reasons discussed above. The accrued interest on unrecognized tax benefits was $2.2 million at September 26, 2020. The Company estimates that it is reasonably possible that the unrecognized tax benefits will decrease by approximately $1.0 million over the next twelve-month period, primarily due to expiring statutes of limitations. The Company conducts business in a number of tax jurisdictions. As a result, it is subject to tax audits on a regular basis including, but not limited to, such major jurisdictions as the U.S., the U.K., China, France, Germany, and Canada. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2017. The Company and certain of its subsidiaries have ongoing tax controversies in the U.S., Canada, Germany, and France. The Company does not anticipate resolution of these audits will have a material impact on its consolidated financial statements.
