Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation As contemplated by the Securities and Exchange Commission (the “Commission”) instructions to Form 10-Q, the following footnotes have been condensed and, therefore, do not contain all disclosures required in connection with annual financial statements. Reference should be made to the Company’s year-end financial statements and notes thereto contained in its Annual Report on Form 10-K for the fiscal year ended December 29, 2019, as filed with the Commission. The financial information included in this report has been prepared by the Company, without audit. In the opinion of management, the financial information included in this report contains all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature unless otherwise disclosed. Nevertheless, the results shown for interim periods are not necessarily indicative of results to be expected for the full year. The December 29, 2019, consolidated condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (“GAAP”). The nine month period ended October 4, 2020 includes 40 weeks, and the nine month period ended September 29, 2019 includes 39 weeks. The three month periods ended October 4, 2020 and September 29, 2019 both include 13 weeks. Risks and Uncertainties The World Health Organization declared the COVID-19 outbreak a pandemic, and many companies have experienced disruptions in their operations. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that, except for the goodwill and intangible asset impairment discussed in Note 10 “Goodwill and Intangible Assets,” the decline in 2020 revenue, and its consequent impacts on production volume, operating income, net income, cash flows, and order rates, there were no other material adverse impacts on the Company’s results of operations and financial position at October 4, 2020. The Company’s primary credit facility has various financial and other covenants including, but not limited to, a covenant to not exceed a maximum net debt to EBITDA ratio, as defined by the credit facility agreement. On July 15, 2020, the Company amended its Syndicated Credit Facility; see Note 5 entitled “Long-Term Debt” for additional information. The full extent of the future impact of COVID-19 on the Company’s operations is uncertain. A prolonged COVID-19 pandemic may continue to have a material adverse impact on our operations, financial condition, and supply chains. It may negatively impact our ability to collect outstanding receivables, manage inventory, and service customers. The impact of COVID-19 could result in additional impairment losses related to goodwill, intangible assets, and property, plant and equipment. As the virus spreads through communities, it could impact the physical health, mental health, and productivity of our workforce as many of them are required to shelter in place and work from home for prolonged periods of time, and it could also impact our ability to reach our customers and collaborate with them as they are required to shelter in place and work from home for prolonged periods of time. The COVID-19 pandemic is having broad and negative implications on the global economy, which affects the size and timing of our customers’ capital budgets, and could result in delays or terminations of new and existing renovation projects, remodeling projects, new construction projects, and other projects where our products are used. COVID-19 Impact We continue to monitor our operations and have implemented various programs to mitigate the effects of COVID-19 on our business including reductions in employee headcount, labor costs, marketing expenses, consulting spend, travel costs, various other costs, and capital expenditures, as well as suspending and reducing shifts in our production facilities, temporarily furloughing employees, and implementing other cost reduction or avoidance initiatives. Government grants and payroll protection programs are available globally to provide assistance to companies impacted by the pandemic. The Coronavirus Aid, Relief and Economic Security Act (“ CARES Act”) enacted in the United States (see Note 13 entitled “Income Taxes” for additional information) and a payroll protection program enacted in the Netherlands (the “NOW Program”) provide benefits related to payroll costs either as reimbursements, lower payroll tax rates or deferral of payroll tax payments. The NOW Program provides eligible companies with reimbursement of labor costs as an incentive to retain employees on the payroll. During fiscal year 2020 year to date, the Company recognized benefits under several payroll protection programs as reductions to payroll costs. Reclassifications In fiscal year 2020, the Company made certain classification and presentation changes related to customer service and other costs. Previously, these costs were presented as a component of cost of sales. Beginning in fiscal year 2020, these costs are presented as a component of selling, general and administrative (“SG&A”) expense. The Company determined that this change better reflects how management views and operates the business. Reclassifications of the comparative prior year 2019 amounts have been made to conform to the current presentation as follows: Three Months Ended September 29, 2019 Statement of Operations Line Item As Reported Reclassification As Reclassified (In thousands) Cost of Sales $ 212,590 $ (1,982) $ 210,608 Selling, General and Administrative Expenses 91,414 1,982 93,396 Total $ 304,004 $ — $ 304,004 Nine Months Ended September 29, 2019 Statement of Operations Line Item As Reported Reclassification As Reclassified (In thousands) Cost of Sales $ 613,797 $ (5,246) $ 608,551 Selling, General and Administrative Expenses 286,123 5,246 291,369 Total $ 899,920 $ — $ 899,920 Recently Adopted Accounting Pronouncements On December 30, 2019, the Company adopted Accounting Standards Codification (“ASC”) Topic 326, Credit Losses. This standard requires a financial asset (including trade receivables) to be presented at the net amount expected to be collected through the use of valuation allowances for credit losses. The income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The Company adopted the new standard using a modified retrospective approach with no cumulative-effect adjustment to retained earnings to recognize expected credit losses on trade accounts receivable. The adoption of this standard did not have a material impact to the Company’s consolidated financial statements. On December 30, 2019, the Company adopted Accounting Standards Update (“ASU”) 2017-04, “Intangibles - Goodwill and Other,” that provides for the elimination of Step 2 from the goodwill impairment test. Under the new guidance, impairment charges are recognized to the extent the carrying amount of a reporting unit exceeds its fair value with certain limitations. See Note 10 entitled “Goodwill and Intangible Assets” for additional information. On December 30, 2019, the Company adopted ASU 2018-13, “Changes to the Disclosure Requirements for Fair Value Measurement.” This standard eliminates the current requirement to disclose the amount or reason for transfers between level 1 and level 2 of the fair value hierarchy and the requirement to disclose the valuation methodology for level 3 fair value measurements. The standard includes additional disclosure requirements for level 3 fair value measurements, including the requirement to disclose the changes in unrealized gains and losses in other comprehensive income during the period and permits the disclosure of other relevant quantitative information for certain unobservable inputs. The adoption of this standard did not have a material impact to the Company’s consolidated financial statements. On December 30, 2019, the Company adopted ASU 2018-15, “Internal-Use Software - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement.” This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement service contract with the guidance to capitalize implementation costs of internal use software. The ASU also requires that the costs for implementation activities during the application development phase be capitalized in a hosting arrangement service contract, and costs during the preliminary and post implementation phase are expensed. The Company adopted this standard, which will be applied on a prospective basis, with no material impact to the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740 related to intraperiod tax allocation, the calculation of income taxes in interim periods, and the accounting for outside basis differences of foreign subsidiaries and equity method investments. The amendments also improve consistent application of and simplify GAAP for other areas of ASC Topic 740, including franchise or similar taxes partially based on income, the accounting for a step-up in tax basis goodwill, and interim recognition of an enacted change in tax laws or rates, by clarifying and amending existing guidance. This new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company is currently evaluating the impact of adoption of this standard but does not anticipate that the adoption will have a material effect on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This standard addresses the risks from the discontinuation of the London Interbank Offered Rate (LIBOR) and provides optional expedients and exceptions to contracts, hedging relationships and other transactions that reference LIBOR if certain criteria are met. This new guidance is effective and may be applied beginning March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adoption of this standard.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE The Company computes basic earnings or loss per share (“EPS”) by dividing net income or loss by the weighted average common shares outstanding, including participating securities outstanding, during the period as discussed below. Diluted EPS reflects the potential dilution beyond shares for basic EPS that could occur if securities or other contracts to issue common stock were exercised, converted into common stock or resulted in the issuance of common stock that would have shared in the Company’s earnings. The Company includes all unvested stock awards which contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, in the number of shares outstanding in the basic and diluted EPS calculations when the inclusion of these shares would be dilutive. Unvested share-based awards of restricted stock are paid dividends equally with all other shares of common stock. As a result, the Company includes all outstanding restricted stock awards in the calculation of basic and diluted EPS. Distributed earnings include common stock dividends and dividends earned on unvested share-based payment awards. Undistributed earnings represent earnings that were available for distribution but were not distributed. The following tables show distributed and undistributed earnings: Three Months Ended Nine Months Ended Earnings (Loss) Per Share October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 Basic Earnings (Loss) Per Share: Distributed Earnings $ 0.01 $ 0.07 $ 0.09 $ 0.19 Undistributed Earnings (Loss) 0.09 0.38 (1.65) 0.87 Total $ 0.10 $ 0.45 $ (1.56) $ 1.06 Diluted Earnings (Loss) Per Share: Distributed Earnings $ 0.01 $ 0.07 $ 0.09 $ 0.19 Undistributed Earnings (Loss) 0.09 0.38 (1.65) 0.87 Total $ 0.10 $ 0.45 $ (1.56) $ 1.06 Basic Earnings (Loss) Per Share $ 0.10 $ 0.45 $ (1.56) $ 1.06 Diluted Earnings (Loss) Per Share $ 0.10 $ 0.45 $ (1.56) $ 1.06 The following table presents net income that was attributable to participating securities: Three Months Ended Nine Months Ended October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In millions) Net Income Attributable to Participating Securities $ — $ 0.2 $ — $ 0.6 The weighted average shares for basic and diluted EPS were as follows: Three Months Ended Nine Months Ended October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In thousands) Weighted Average Shares Outstanding 58,140 57,915 58,055 58,599 Participating Securities 452 518 452 518 Shares for Basic EPS 58,592 58,433 58,507 59,117 Dilutive Effect of Stock Options — 1 — 5 Shares for Diluted EPS 58,592 58,434 58,507 59,122 For all periods presented, there were no stock options or participating securities excluded from the computation of diluted EPS.

Long-term Debt

Long-term Debt	9 Months Ended

Debt Disclosure [Abstract]
Long-term Debt	LONG-TERM DEBT Syndicated Credit Facility On July 15, 2020, the Company entered into a second amendment to its Syndicated Credit Facility (the “Facility”). This amendment, among other changes, provides for the following: (1) amends the consolidated net leverage ratio covenant making it less restrictive for a period of seven consecutive fiscal quarters beginning with the third quarter of fiscal year 2020 through the first quarter of fiscal year 2022 (the “Relief Period”); (2) amends the pricing grid used to determine interest rate margins on outstanding loans as well as the commitment fee on the unused portion of the Facility to include additional consolidated net leverage ratio levels with increased pricing at higher levels of leverage; (3) amends interest rate provisions to provide for an interest rate floor of either 0.00% or 0.75%, as applicable, on certain tranches of term loans outstanding; and (4) provides temporary restrictions during the Relief Period on the Company’s ability to make acquisitions, pay dividends, repurchase shares, or enter into new credit facilities without lender consent. The Company incurred approximately $1.5 million in debt issuance costs to execute this amendment. The Facility provides the Company and certain of its subsidiaries a multicurrency revolving loan and U.S. denominated and multicurrency term loans. Interest on base rate loans is charged at varying rates computed by applying a margin depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter. Interest on LIBOR-based loans and fees for letters of credit is charged at varying rates computed by applying a margin over the applicable LIBOR rate, depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter. In addition, the Company pays a commitment fee per annum (depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter) on the unused portion of the Facility. As of October 4, 2020, the Company had outstanding $562.3 million of term loan borrowing and $23.7 million of revolving loan borrowings under the Facility, and had $1.6 million in letters of credit outstanding under the Facility. As of December 29, 2019, the Company had outstanding $581.6 million of term loan borrowing and $20.9 million of revolving loan borrowings under the Facility, and had $2.2 million in letters of credit outstanding under the Facility. As of October 4, 2020 and December 29, 2019, the weighted average interest rate on borrowings outstanding under the Facility was 3.15% and 3.27%, respectively. As of October 4, 2020 and December 29, 2019, the carrying value of the Company’s borrowings under the Facility approximates its fair value as the Facility bears interest rates that are similar to existing market rates. Under the Facility, the Company is required to make quarterly amortization payments of the term loan borrowings, which are due on the last day of the calendar quarter. The Company is currently in compliance with all covenants under the Facility and anticipates that it will remain in compliance with the covenants for the foreseeable future. Debt issuance costs associated with term loans are reflected as a reduction of long-term debt in accordance with applicable accounting standards. As these fees are expensed over the life of the outstanding borrowing, the debt balance will increase by the same amount as the fees that are expensed. As of October 4, 2020 and December 29, 2019, the unamortized debt issuance costs recorded as a reduction of long-term debt were $5.9 million and $6.3 million, respectively. Other deferred borrowing costs, which include underwriting, legal and other direct costs related to the issuance of revolving debt, net of accumulated amortization, were $1.5 million and $1.3 million as of October 4, 2020 and December 29, 2019, respectively. These amounts are included in other assets in the Company’s consolidated condensed balance sheets. The Company amortizes these costs over the life of the related debt. Other Lines of Credit Subsidiaries of the Company had an aggregate of the equivalent of $9.6 million and $9.5 million of other lines of credit available as of October 4, 2020 and December 29, 2019, respectively, at interest rates ranging from 2.0% to 6.0% as of both October 4, 2020 and December 29, 2019. As of October 4, 2020 and December 29, 2019, there were no borrowings outstanding under these lines of credit.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS Interest Rate Risk Management In the third quarter of 2017 and the first quarter of 2019, the Company entered into interest rate swap transactions in notional amounts of $100 million and $150 million, respectively, to fix the variable interest rate on a portion of its term loan borrowing in order to manage a portion of its exposure to interest rate fluctuations. The Company’s objective and strategy with respect to these interest rate swaps is to protect the Company against adverse fluctuations in interest rates by reducing its exposure to variability to cash flows relating to interest payments on a portion of its outstanding debt. The Company is meeting its objective by hedging the risk of changes in its cash flows (interest payments) attributable to changes in LIBOR, the designated benchmark interest rate being hedged (the “hedged risk”), on an amount of the Company’s debt principal equal to the outstanding swap notional amounts. Cash Flow Interest Rate Swaps Both of the interest rate swaps described above are designated and qualify as cash flow hedges of forecasted interest payments. The Company reports the changes in fair value of the swaps as a component of other comprehensive income (or other comprehensive loss). The aggregate notional amount of the interest rate swaps as of October 4, 2020 was $250 million. Forward Contracts Our European operations, from time to time, are party to currency forward contracts designed to hedge the cash flow risk of intercompany sales from the manufacturing facility in Europe to the Americas. The Company’s objective and strategy with respect to these currency forward contracts is to protect the Company against adverse fluctuations in currency rates by reducing its exposure to variability in cash flows related to receipt of payment on intercompany sales. As of October 4, 2020, there were no active forward currency contracts. Derivative Transactions Not Designated as Hedging Instruments Our Asia-Pacific operations, from time to time, purchase foreign currency options to economically hedge inventory purchases denominated in foreign currencies other than their functional currency. The Company’s objective with respect to these foreign currency options is to protect the Company against adverse fluctuations in currency rates by reducing its exposure to variability in cash flows related to payment on inventory purchases. These options are classified as non-designated derivative instruments. Gains and losses on the changes in fair value of these foreign currency options are recognized in earnings each period. As of October 4, 2020, the Company had outstanding foreign currency options with an aggregate notional amount of $16.9 million.

That cost will be recognized over the period in which the employee is required to provide the services – the requisite service period (usually the vesting period) – in exchange for the award. All outstanding stock options vested prior to the end of 2013, and therefore there was no stock option compensation expense in the first nine months of 2020 or 2019. As of October 4, 2020, there were no stock options outstanding and exercisable. There were no stock options granted in the first nine months of 2020 or 2019. There were 7,500 stock options exercised and 20,000 stock options expired in the first nine months of 2020. There were 10,000 stock options exercised in the first nine months of 2019 and 5,000 stock option forfeitures during those nine months. Restricted Stock Awards During the nine months ended October 4, 2020 and September 29, 2019, the Company granted restricted stock awards for 308,100 and 224,000 shares of common stock, respectively. Awards of restricted stock (or a portion thereof) vest with respect to each recipient over a one to three-year period from the date of grant, provided the individual remains in the employment or service of the Company as of the vesting date. Additionally, certain awards (or a portion thereof) could vest earlier in the event of a change in control of the Company, or upon involuntary termination without cause. Compensation expense related to restricted stock grants was $0.6 million and $2.5 million for the nine months ended October 4, 2020, and September 29, 2019, respectively. The Company has reduced its expense for restricted stock forfeited during the period. The following table summarizes restricted stock outstanding as of October 4, 2020, as well as activity during the nine months then ended: Restricted Shares Weighted Average Outstanding at December 29, 2019 468,200 $ 28.63 Granted 308,100 13.08 Vested (167,000) 19.33 Forfeited or canceled (157,800) 19.59 Outstanding at October 4, 2020 451,500 $ 24.62 As of October 4, 2020, the unrecognized total compensation cost related to unvested restricted stock was $3.8 million. That cost is expected to be recognized by the end of 2023. Performance Share Awards During the nine months ended October 4, 2020 and September 29, 2019, the Company issued awards of performance shares to certain employees. These awards vest based on the achievement of certain performance-based goals over a performance period of one to three years, subject to the employee’s continued employment, and will be settled in shares of our common stock or in cash at the Company’s election. The number of shares that may be issued in settlement of the performance shares to the award recipients may be greater (up to 200%) or lesser than the nominal award amount depending on actual performance achieved as compared to the performance targets set forth in the awards. The following table summarizes the performance shares outstanding as of October 4, 2020, as well as the activity during the nine months then ended: Performance Shares Weighted Average Outstanding at December 29, 2019 512,000 $ 19.71 Granted 263,700 15.36 Vested (164,300) 19.74 Forfeited or canceled (200,700) 19.61 Outstanding at October 4, 2020 410,700 $ 16.96 Compensation expense (benefit) related to the performance shares was $(2.0) million and $4.0 million for the nine months ended October 4, 2020 and September 29, 2019, respectively. The Company has reduced its expense for performance shares forfeited during the period. Unrecognized compensation expense related to these performance shares was approximately $6.9 million as of October 4, 2020. Depending on the performance of the Company, any compensation expense related to these outstanding performance shares will be recognized by the end of 2023. Tax expense recognized with regard to restricted stock and performance shares was approximately $0.3 million for the nine months ended October 4, 2020.

Leases [Abstract]
Leases	LEASES General The Company has operating and finance leases for manufacturing equipment, corporate offices, showrooms, distribution facilities, design centers, as well as computer and office equipment. The Company’s leases have terms ranging from 1 to 20 years, some of which may include options to extend the lease term for up to 5 years, and certain leases may include an option to terminate the lease. Our lease accounting may include these options to extend or terminate a lease when it is reasonably certain that we will exercise that option. The Company records a right-of-use asset and lease liability for leases extending beyond one year for operating and finance leases once a contract that contains a lease is executed and we have the right to control the use of the leased asset. The right-of-use asset is measured as the present value of the lease obligation. The discount rate used to calculate the present value of the lease liability was the Company’s incremental borrowing rate for the applicable geographical region. As of October 4, 2020, there were no significant leases that had not commenced as of the end of the third quarter. The table below represents a summary of the balances recorded in the consolidated condensed balance sheets related to our leases as of October 4, 2020 and December 29, 2019: October 4, 2020 December 29, 2019 Balance Sheet Location Operating Leases Finance Leases Operating Leases Finance Leases (In thousands) Operating lease right-of-use assets $ 99,815 $ 107,044 Current portion of operating lease liabilities $ 14,015 $ 15,914 Operating lease liabilities 87,276 91,829 Total operating lease liabilities $ 101,291 $ 107,743 Property and equipment $ 5,786 $ 5,007 Accrued expenses $ 1,415 $ 1,489 Other long-term liabilities 2,299 1,673 Total finance lease liabilities $ 3,714 $ 3,162 Lease Costs Three Months Ended Nine Months Ended October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In thousands) Finance lease cost: Amortization of right-of-use assets $ 176 $ 112 $ 811 $ 536 Interest on lease liabilities 22 12 56 31 Operating lease cost 6,095 6,023 19,076 17,624 Short-term lease cost 85 363 426 1,509 Variable lease cost 1,089 561 2,659 1,319 Total lease cost $ 7,467 $ 7,071 $ 23,028 $ 21,019 Other Supplemental Information Three Months Ended Nine Months Ended October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from finance leases $ 22 $ 12 $ 56 $ 31 Operating cash flows from operating leases 5,528 5,653 16,978 16,158 Financing cash flows from finance leases 442 291 1,252 808 Right-of-use assets obtained in exchange for new finance lease liabilities 1,156 252 1,709 803 Right-of-use assets obtained in exchange for new operating lease liabilities 1,517 1,437 5,582 7,973 Lease Term and Discount Rate The table below presents the weighted average remaining lease terms and discount rates for finance and operating leases as of October 4, 2020 and December 29, 2019: October 4, 2020 December 29, 2019 Weighted-average remaining lease term – finance leases (in years) 3.29 2.76 Weighted-average remaining lease term – operating leases (in years) 10.59 10.60 Weighted-average discount rate – finance leases 2.75 % 2.06 % Weighted-average discount rate – operating leases 5.96 % 5.86 % Maturity Analysis A maturity analysis of lease payments under non-cancellable leases is presented as follows: Fiscal Year Operating Leases Finance Leases (In thousands) 2020 (excluding the nine months ended October 4, 2020) $ 5,262 $ 411 2021 18,529 1,367 2022 15,126 903 2023 12,464 680 2024 10,513 407 Thereafter 78,668 153 Total future minimum lease payments (undiscounted) 140,562 3,921 Less: Present value discount (39,271) (207) Total lease liability $ 101,291 $ 3,714 Policy Elections The Company made an accounting policy election not to separate lease and non-lease components for all asset classes, except for data center assets, and will account for the lease payments as a single component. The Company also made an accounting policy election to exclude leases with an initial term of 12 months or less from the calculation of the right-of-use asset and lease liability recorded on the consolidated condensed balance sheets. These leases primarily represent month-to-month operating leases for vehicles and office equipment where we were reasonably certain that we would not elect an option to extend the lease.

Retirement Benefits [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS On December 31, 2019, a plan amendment was executed to eliminate future service accruals in the Dutch defined benefit plan, resulting in a curtailment of the plan. This plan remains in existence and will continue to pay vested benefits. Active participants will no longer accrue benefits after December 31, 2019, and instead will participate in an industry-wide multi-employer plan beginning in fiscal year 2020. During the three and nine months ended October 4, 2020, the Company recorded multi-employer pension expense related to multi-employer contributions of $0.6 million and $1.9 million, respectively. The following tables provide the components of net periodic benefit cost for the three and nine months ended October 4, 2020 and September 29, 2019: Three Months Ended Nine Months Ended Defined Benefit Retirement Plans (Europe) October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In thousands) Service cost $ — $ 181 $ — $ 550 Interest cost 907 1,223 2,668 3,770 Expected return on assets (1,082) (1,378) (3,184) (4,251) Amortization of prior service cost 27 16 79 48 Amortization of net actuarial losses 335 240 981 742 Net periodic benefit cost $ 187 $ 282 $ 544 $ 859 Three Months Ended Nine Months Ended Salary Continuation Plan October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In thousands) Interest cost $ 234 $ 288 $ 703 $ 865 Amortization of net actuarial losses 140 94 419 281 Net periodic benefit cost $ 374 $ 382 $ 1,122 $ 1,146 Three Months Ended Nine Months Ended nora Defined Benefit Plan October 4, 2020 September 29, 2019 October 4, 2020 September 29, 2019 (In thousands) Service cost $ 274 $ 213 $ 791 $ 646 Interest cost 117 170 338 515 Amortization of net actuarial losses 58 — 168 — Net periodic benefit cost $ 449 $ 383 $ 1,297 $ 1,161 In accordance with applicable accounting standards, the service cost component of net periodic benefit costs is presented within Operating Income in the consolidated condensed statements of operations, while all other components of net periodic benefit costs are presented within other expense in the consolidated condensed statements of operations.

Goodwill and Intangible Assets

Goodwill and Intangible Assets (Notes)	9 Months Ended

Goodwill [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	GOODWILL AND INTANGIBLE ASSETS During the first quarter of 2020, we performed a qualitative assessment of goodwill impairment indicators, considering macroeconomic conditions related to the COVID-19 pandemic and its potential impact to sales and operating income. We expect that the duration of the COVID-19 pandemic and its adverse impacts on the global economy, global travel restrictions, COVID-19 related government shutdowns, disruptions to our supply chain, distribution disruption, and disruption to our customers’ plans to spend capital on projects that use our products and services will result in lower revenue and operating income. As a result, we determined that there were indicators of impairment, and the Company proceeded with a quantitative assessment of goodwill for all reporting units at the end of the first quarter. In performing the first quarter quantitative goodwill impairment testing, the Company prepared valuations of reporting units on both a market comparable methodology and an income methodology, and those valuations were compared with the respective carrying values of the reporting units to determine whether any goodwill impairment existed. Our reporting units are one level below our reporting segment level. In preparing the valuations, past, present and future expectations of performance were considered, including the impact of the COVID-19 pandemic. This methodology was consistent with the approach used to perform the annual quantitative goodwill assessment in prior years. The weighted average cost of capital used in the goodwill impairment testing ranged between 10.0% and 10.5%, which primarily fluctuated based on a country risk premium assigned to the geographical region of the reporting unit. There is inherent uncertainty associated with key assumptions used in our impairment testing including the duration of the economic downturn associated with the COVID-19 pandemic and the recovery period. As a result of the first quarter assessment, we determined that the fair value for two reporting units was less than the carrying value and recognized a goodwill impairment loss of $116.5 million in the first quarter of 2020. The expected decline in revenue due to the impact of COVID-19 contributed to the lower fair value of our Europe and Asia-Pacific reporting units. As such, the goodwill impairment loss was allocated to our Europe and Asia-Pacific reporting units in the amounts of $99.2 million and $17.3 million, respectively. We determined that the goodwill in our Americas reporting unit was not impaired as the fair value exceeded the carrying value by more than 90% at April 5, 2020. There were no indicators of additional goodwill impairment as of October 4, 2020. The changes in the carrying amounts of goodwill for the nine months ended October 4, 2020 are as follows: BALANCE, AT ACQUISITIONS PURCHASE IMPAIRMENT FOREIGN BALANCE, AT (In thousands) $ 257,439 $ — $ — $ (116,495) $ 13,686 $ 154,630 Additionally, we determined that the trademarks and trade names intangible assets related to the acquired nora business were also impaired and recognized an impairment loss of $4.8 million in the first quarter of 2020. The carrying value of intangible assets after the impairment was $85.5 million at October 4, 2020. There were no indicators of additional intangible asset impairment as of the end of the third quarter of 2020.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	SEGMENT INFORMATION Based on applicable accounting standards, the Company has determined that it has three operating segments – namely, the Americas, Europe and Asia-Pacific geographic regions. Pursuant to accounting standards, the Company has aggregated the three operating segments into one reportable segment because they have similar economic characteristics, and the operating segments are similar in all of the following areas: (a) the nature of the products and services; (b) the nature of the production processes; (c) the type or class of customer for their products and services; (d) the methods used to distribute their products or provide their services; and (e) the nature of the regulatory environment. While the Company operates as one reportable segment for the reasons discussed, included below is selected information on our operating segments.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company determines its provision for income taxes for interim periods using an estimate of its annual effective tax rate and records any changes affecting the estimated annual effective tax rate in the interim period in which the change occurs, including discrete tax items. During the nine months ended October 4, 2020, the Company recorded a total income tax provision of $5.7 million on a pre-tax loss of $85.8 million resulting in an effective tax rate of (6.7)%. The effective tax rate for this period was primarily impacted by a non-deductible goodwill impairment. Excluding the impact of the goodwill impairment, the effective tax rate was 18.7% for the period compared to 22.0% during the nine months ended September 29, 2019. The decrease in the effective tax rate, excluding the goodwill impairment, was due to favorable impacts of amending prior year tax returns and the retroactive election of the GILTI High-tax Exclusion in the 2019 tax return, which were offset by the unfavorable changes related to unrecognized tax benefits and the non-deductible penalty to settle the SEC matter, referenced in the disclosure set forth in Note 17 to the consolidated financial statements included in Item 8 of the December 29, 2019 Annual Report on Form 10-K. In the first nine months of 2020, the Company increased its liability for unrecognized tax benefits by $0.1 million. As of October 4, 2020, the Company had accrued approximately $25.6 million for unrecognized tax benefits. In accordance with applicable accounting standards, the Company’s deferred tax asset as of October 4, 2020 reflects a reduction for $2.8 million of these unrecognized tax benefits. In October 2020, the statute of limitations for the 2016 U.S. federal income tax return closed. As a result of this lapse in the statute of limitations, the Company will recognize $14.4 million of unrecognized tax benefits in the fourth quarter of 2020.

Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment Charges	RESTRUCTURING CHARGES For the nine months ended October 4, 2020, the Company recorded a reduction of $3.2 million of previously recognized restructuring charges due to changes in expected cash payments. At October 4, 2020, the aggregate restructuring reserve was $3.9 million for both the 2019 and 2018 restructuring plans. Below is a discussion of the restructuring plan activities by year. 2019 Restructuring Plan On December 23, 2019, the Company committed to a new restructuring plan that continues to focus on efforts to improve efficiencies and decrease costs across its worldwide operations, and more closely align its operating structure with its business strategy. The plan involved a reduction of approximately 105 employees and early termination of two office leases. As a result of this plan, the Company recorded a pre-tax restructuring charge in the fourth quarter of 2019 of approximately $9.0 million. The charge was comprised of severance expenses ($8.8 million) and lease exit costs ($0.2 million). The restructuring plan is expected to result in cash expenditures of approximately $9.0 million for payment of the employee severance and lease exit costs, as described above. The Company expects to complete the restructuring plan in fiscal year 2020 and expects the plan to yield annualized savings of approximately $6.0 million. A portion of the annualized savings is expected to be realized on the income statement in fiscal year 2020, with the remaining portion of the annualized savings expected to be realized in fiscal year 2021. A reconciliation of the 2019 plan restructuring reserve is presented below: BALANCE, AT DEDUCTIONS 2020 CHARGED TO EXPENSES 2020 BALANCE, AT (In thousands) Workforce Reduction $ 8,634 $ (2,648) $ (2,234) $ 3,752 Other Exit Costs 139 (139) — — Total $ 8,773 $ (2,787) $ (2,234) $ 3,752 2018 Restructuring Plan On December 29, 2018, the Company committed to a restructuring plan in its continuing efforts to improve efficiencies and decrease costs across its worldwide operations, and more closely align its operating structure with its business strategy. The plan involved (i) a restructuring of its sales and administrative operations in the United Kingdom, (ii) a reduction of approximately 200 employees, primarily in the Europe and Asia-Pacific geographic regions, and (iii) the write-down of certain underutilized and impaired assets that included information technology assets and obsolete manufacturing equipment. The restructuring plan was substantially completed at the end of the second quarter of 2020. The Company redeployed essentially all of the anticipated savings toward the funding of sales and strategic growth initiatives, yielding negligible net savings on the Company’s income statement. A reconciliation of the 2018 plan restructuring reserve is presented below: BALANCE, AT DEDUCTIONS 2020 CHARGED TO EXPENSES 2020 BALANCE, AT (In thousands) Workforce Reduction $ 1,898 $ (1,576) $ (223) $ 99 Other Exit Costs 774 (75) (699) — Total $ 2,672 $ (1,651) $ (922) $ 99

Subsequent Events	SUBSEQUENT EVENTS Cost Reducing Initiatives and Related Charges As we continue to monitor the impact of COVID-19 and mitigate its effects to our operations, the Company expects to continue to pursue a variety of cost reducing initiatives including but not limited to voluntary incentive separation programs, temporary employee furloughs and other time-and-pay reduction programs, applications to participate in various government sponsored “wage support” programs, involuntary separations where necessary to streamline roles and responsibilities, potential facility closures to streamline operations, and various other cost reducing and cost avoidance activities. Unrecognized Tax Benefits In October 2020, the statute of limitations for the 2016 U.S. federal income tax return closed. As a result of this lapse in the statute of limitations, the Company will recognize $14.4 million of unrecognized tax benefits in the fourth quarter of 2020.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation As contemplated by the Securities and Exchange Commission (the “Commission”) instructions to Form 10-Q, the following footnotes have been condensed and, therefore, do not contain all disclosures required in connection with annual financial statements. Reference should be made to the Company’s year-end financial statements and notes thereto contained in its Annual Report on Form 10-K for the fiscal year ended December 29, 2019, as filed with the Commission. The financial information included in this report has been prepared by the Company, without audit. In the opinion of management, the financial information included in this report contains all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature unless otherwise disclosed. Nevertheless, the results shown for interim periods are not necessarily indicative of results to be expected for the full year. The December 29, 2019, consolidated condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (“GAAP”).
Concentration Risk Disclosure	Risks and Uncertainties The World Health Organization declared the COVID-19 outbreak a pandemic, and many companies have experienced disruptions in their operations. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that, except for the goodwill and intangible asset impairment discussed in Note 10 “Goodwill and Intangible Assets,” the decline in 2020 revenue, and its consequent impacts on production volume, operating income, net income, cash flows, and order rates, there were no other material adverse impacts on the Company’s results of operations and financial position at October 4, 2020. The Company’s primary credit facility has various financial and other covenants including, but not limited to, a covenant to not exceed a maximum net debt to EBITDA ratio, as defined by the credit facility agreement. On July 15, 2020, the Company amended its Syndicated Credit Facility; see Note 5 entitled “Long-Term Debt” for additional information. The full extent of the future impact of COVID-19 on the Company’s operations is uncertain. A prolonged COVID-19 pandemic may continue to have a material adverse impact on our operations, financial condition, and supply chains. It may negatively impact our ability to collect outstanding receivables, manage inventory, and service customers. The impact of COVID-19 could result in additional impairment losses related to goodwill, intangible assets, and property, plant and equipment.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On December 30, 2019, the Company adopted Accounting Standards Codification (“ASC”) Topic 326, Credit Losses. This standard requires a financial asset (including trade receivables) to be presented at the net amount expected to be collected through the use of valuation allowances for credit losses. The income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The Company adopted the new standard using a modified retrospective approach with no cumulative-effect adjustment to retained earnings to recognize expected credit losses on trade accounts receivable. The adoption of this standard did not have a material impact to the Company’s consolidated financial statements. On December 30, 2019, the Company adopted Accounting Standards Update (“ASU”) 2017-04, “Intangibles - Goodwill and Other,” that provides for the elimination of Step 2 from the goodwill impairment test. Under the new guidance, impairment charges are recognized to the extent the carrying amount of a reporting unit exceeds its fair value with certain limitations. See Note 10 entitled “Goodwill and Intangible Assets” for additional information. On December 30, 2019, the Company adopted ASU 2018-13, “Changes to the Disclosure Requirements for Fair Value Measurement.” This standard eliminates the current requirement to disclose the amount or reason for transfers between level 1 and level 2 of the fair value hierarchy and the requirement to disclose the valuation methodology for level 3 fair value measurements. The standard includes additional disclosure requirements for level 3 fair value measurements, including the requirement to disclose the changes in unrealized gains and losses in other comprehensive income during the period and permits the disclosure of other relevant quantitative information for certain unobservable inputs. The adoption of this standard did not have a material impact to the Company’s consolidated financial statements. On December 30, 2019, the Company adopted ASU 2018-15, “Internal-Use Software - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement.” This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement service contract with the guidance to capitalize implementation costs of internal use software. The ASU also requires that the costs for implementation activities during the application development phase be capitalized in a hosting arrangement service contract, and costs during the preliminary and post implementation phase are expensed. The Company adopted this standard, which will be applied on a prospective basis, with no material impact to the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740 related to intraperiod tax allocation, the calculation of income taxes in interim periods, and the accounting for outside basis differences of foreign subsidiaries and equity method investments. The amendments also improve consistent application of and simplify GAAP for other areas of ASC Topic 740, including franchise or similar taxes partially based on income, the accounting for a step-up in tax basis goodwill, and interim recognition of an enacted change in tax laws or rates, by clarifying and amending existing guidance. This new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company is currently evaluating the impact of adoption of this standard but does not anticipate that the adoption will have a material effect on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This standard addresses the risks from the discontinuation of the London Interbank Offered Rate (LIBOR) and provides optional expedients and exceptions to contracts, hedging relationships and other transactions that reference LIBOR if certain criteria are met. This new guidance is effective and may be applied beginning March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adoption of this standard.
