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. 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. 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 impairment discussed in Note 10 “ Goodwill and Intangible Assets ” there were no other material adverse impacts on the Company’s results of operations and financial position at April 5, 2020 . Our 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. In the event we believe we are unable to maintain compliance with such covenants in the future, we will take mitigating actions prior to such potential breach. The full extent of the future impact of COVID-19 on the Company’s operations is uncertain. A prolonged COVID-19 pandemic could have a material adverse impact on our operations, financial condition, our ability to stay in compliance with our debt covenants, our ability to refinance our existing indebtedness and our ability to collect outstanding receivables. The impact of COVID-19 could also result in additional impairment losses related to goodwill, all intangible assets and property, plant and equipment. Change in Accounting Principle In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Improvements to Share Based Payment Accounting,” to simplify the accounting for share based payment transactions. We previously adopted the provisions of this ASU in fiscal year 2017 and noted at that time that we would apply the policy election to estimate forfeitures of share based awards and reduce stock compensation expense based on that estimate. On December 30, 2019, the Company elected to change its forfeiture method related to share based awards and will now account for forfeitures as they occur, as allowed by ASU 2016-09. The Company believes that this change is preferable because it achieves better correlation of stock compensation expense with the requisite service period. The cumulative impact of this change did not have a material effect on the Company’s consolidated financial statements and is not expected to have a material effect on the full fiscal year 2020 consolidated financial statements. As a result, the cumulative effect of $1.4 million was recognized in selling, general and administrative expenses (“SG&A”) within the consolidated condensed statement of operations during the first quarter of fiscal year 2020 . Since the impact of this change is not material, prior period amounts were not retrospectively adjusted. Reclassifications Beginning in the first quarter of fiscal 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 will be presented as a component of SG&A. 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 March 31, 2019 Statement of Operations Line Item As Reported Reclassification As Reclassified (In thousands) Cost of Sales $ 182,290 $ (1,124 ) $ 181,166 Selling, General and Administrative Expenses 99,011 1,124 100,135 Total $ 281,301 $ — $ 281,301 Recently Adopted Accounting Pronouncements On December 30, 2019, the Company adopted Accounting Standards Codification 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 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 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 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 our 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 April 5, 2020 March 31, 2019 Earnings (Loss) Per Share: Basic Earnings (Loss) Per Share: Distributed Earnings $ 0.07 $ 0.07 Undistributed Earnings (Loss) (1.82 ) 0.05 Total $ (1.75 ) $ 0.12 Diluted Earnings (Loss) Per Share: Distributed Earnings $ 0.07 $ 0.07 Undistributed Earnings (Loss) (1.82 ) 0.05 Total $ (1.75 ) $ 0.12 Basic earnings (loss) per share $ (1.75 ) $ 0.12 Diluted earnings (loss) per share $ (1.75 ) $ 0.12 The following table presents net income that was attributable to participating securities: Three Months Ended April 5, 2020 March 31, 2019 (In millions) Net Income Attributable to Participating Securities $ — $ 0.1 The weighted average shares for basic and diluted EPS were as follows: Three Months Ended April 5, 2020 March 31, 2019 (In thousands) Weighted Average Shares Outstanding 58,060 59,065 Participating Securities 390 567 Shares for Basic EPS 58,450 59,632 Dilutive Effect of Stock Options 2 10 Shares for Diluted EPS 58,452 59,642 For all periods presented, there were no stock options or participating securities excluded from the computation of diluted EPS.

Debt Disclosure [Abstract]
Long-term Debt	LONG-TERM DEBT Syndicated Credit Facility At April 5, 2020 , the Company maintained an amended and restated Syndicated Credit Facility (the “Facility”) which provided to the Company and certain of its subsidiaries a multicurrency revolving loan and U.S. denominated and multicurrency term loans. Interest on base rate loans was 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 were 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 paid 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. Debt issuance costs 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 April 5, 2020 , the unamortized debt costs recorded as a reduction of long-term debt were $5.8 million . As of April 5, 2020 , the Company had outstanding $570.7 million of term loan borrowing and $62.4 million of revolving loan borrowings under the Facility, and had $1.6 million in letters of credit outstanding under the Facility. As of April 5, 2020 , the weighted average interest rate on borrowings outstanding under the Facility was 2.91% . As of April 5, 2020 , 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. Other Lines of Credit Subsidiaries of the Company have an aggregate of the equivalent of $9.0 million of other lines of credit available at interest rates ranging from 2.0% to 6.0% . As of April 5, 2020 , 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 Swap 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 April 5, 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 April 5, 2020 , there were no active forward currency contracts. The table below sets forth the fair value of derivative instruments as of April 5, 2020 (in thousands): Asset Derivatives as of Liability Derivatives as of Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivative instruments designated as hedging instruments: Interest rate swap contracts Other current assets $ — Accrued expenses $ 14,402 $ — $ 14,402 The table below sets forth the fair value of derivative instruments as of December 29, 2019 (in thousands): Asset Derivatives as of Liability Derivatives as of Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivative instruments designated as hedging instruments: Interest rate swap contract Other current assets $ — Accrued expenses $ 5,801 $ — $ 5,801 There was no significant impact to net income or loss from the changes in fair value of derivatives designated as cash flow hedges or from amounts excluded from the assessment of hedge effectiveness during the three months ended April 5, 2020 . We expect that approximately $3.3 million related to cash flow hedges will be reclassified from accumulated other comprehensive loss as an increase to interest expense in the next 12 months . The following table summarizes the impact that changes in the fair value of derivatives designated as cash flow hedges and included in the assessment of hedge effectiveness had on accumulated other comprehensive loss, net of tax, during the three months ended April 5, 2020 and March 31, 2019 (in thousands): Three Months Ended April 5, 2020 March 31, 2019 (In thousands) Foreign currency contracts loss $ — $ (363 ) Interest rate swap contracts loss (6,140 ) (2,943 ) Loss recognized in accumulated other comprehensive loss $ (6,140 ) $ (3,306 ) Gains and losses reclassified from accumulated other comprehensive income (loss) into net income (loss) are discussed in Note 14 entitled “ Items Reclassified From Other Comprehensive Loss

The cumulative effect of this change was $1.4 million of additional expense recognized in selling, general and administrative expenses within the consolidated condensed statement of operations for the three months ended April 5, 2020 . Prior to this change, the Company estimated forfeitures and reduced stock compensation expense based on that estimate. Under the new forfeiture method, the Company will account for forfeitures as they occur as permitted by generally accepted accounting princ iples. The impact of this change would have resulted in a decrease of $0.1 million to stock compensation expense for the period if the forfeiture methodology had not been changed. Stock Option Awards In accordance with accounting standards, the Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. 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 three months of 2020 or 2019 . As of April 5, 2020 , there were 20,000 stock options outstanding and exercisable, at an average exercise price of $12.43 per share. There were no stock options granted in the first three months of 2020 or 2019 . There were 7,500 stock options exercised and no stock options forfeited in the first three months of 2020 . There were 10,000 stock options exercised in the first three months of 2019 and 5,000 stock option forfeitures during those three months. The aggregate intrinsic value of the outstanding and exercisable stock options was not significant as of April 5, 2020 . Restricted Stock Awards During the three months ended April 5, 2020 and March 31, 2019 , the Company granted restricted stock awards for 199,600 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 (benefit) related to restricted stock grants was $(0.7) million and $0.8 million for the three months ended April 5, 2020 , and March 31, 2019 , respectively. The Company has reduced its expense for restricted stock forfeited during the period. As a result of the change in the forfeiture recognition methodology described above, compensation expense (benefit) related to restricted stock grants was impacted by $0.6 million for the cumulative effect of this change. The following table summarizes restricted stock outstanding as of April 5, 2020 , as well as activity during the three months then ended: Restricted Shares Weighted Average Grant Date Fair Value Outstanding at December 29, 2019 468,200 $ 28.63 Granted 199,600 15.41 Vested (132,200 ) 19.24 Forfeited or canceled (145,200 ) 19.86 Outstanding at April 5, 2020 390,400 $ 28.31 As of April 5, 2020 , the unrecognized total compensation cost related to unvested restricted stock was $5.2 million . That cost is expected to be recognized by the end of 2022. Performance Share Awards During the three months ended April 5, 2020 and March 31, 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 April 5, 2020 , as well as the activity during the three months then ended: Shares Weighted Average Grant Date Fair Value Outstanding at December 29, 2019 512,000 $ 19.71 Granted 263,600 15.36 Vested (164,300 ) 19.74 Forfeited or canceled (180,000 ) 19.83 Outstanding at April 5, 2020 431,300 $ 17.00 Compensation expense (benefit) related to the performance shares was $(2.2) million and $2.0 million for the three months ended April 5, 2020 and March 31, 2019 , respectively. The Company has reduced its expense for performance shares forfeited during the period. As a result of the change in the forfeiture recognition methodology described above, compensation expense (benefit) related to performance shares was impacted by $0.8 million for the cumulative effect of this change. Unrecognized compensation expense related to these performance shares was approximately $7.4 million as of April 5, 2020 . Depending on the performance of the Company, any compensation expense related to these outstanding performance shares will be recognized by the end of 2022. Tax expense recognized with regard to restricted stock and performance shares was approximately $1.0 million for the three months ended April 5, 2020 .

Leases [Abstract]
Leases	LEASES General We have operating and finance leases for manufacturing equipment, corporate offices, showrooms, distribution facilities, design centers, as well as computer and office equipment. Our 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. We record a right-of-use asset and lease liability 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 April 5, 2020 , there were no significant right-of-use assets and lease obligations from leases that had not commenced as of the end of the first quarter.

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 months ended April 5, 2020 , the Company recorded multi-employer pension expense of $0.7 million related to multi-employer contributions. The following tables provide the components of net periodic benefit cost for the three -month periods ended April 5, 2020 and March 31, 2019 , respectively: Three Months Ended Defined Benefit Retirement Plans (Europe) April 5, 2020 March 31, 2019 (In thousands) Service cost $ — $ 185 Interest cost 891 1,281 Expected return on assets (1,064 ) (1,445 ) Amortization of prior service cost 26 16 Amortization of net actuarial losses 326 253 Net periodic benefit cost $ 179 $ 290 Three Months Ended Salary Continuation Plan April 5, 2020 March 31, 2019 (In thousands) Service cost $ — $ — Interest cost 234 288 Amortization of net actuarial losses 140 94 Net periodic benefit cost $ 374 $ 382 Three Months Ended Nora Defined Benefit Plan April 5, 2020 March 31, 2019 (In thousands) Service cost $ 258 $ 217 Interest cost 111 174 Net periodic benefit cost $ 369 $ 391 In accordance with applicable accounting standards, the service cost component of net periodic benefit costs is presented within Operating Income in the consolidated condensed statement of operations, while all other components of net periodic benefit costs are presented within other expense in the consolidated condensed statement of operations.

Goodwill and Intangible Assets

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 for the remainder of fiscal 2020. We expect that the duration of the COVID-19 pandemic and the continued impact of global travel restrictions, government shutdowns of non-essential businesses and disruptions to our supply chain and distribution channels to result in lower revenue and operating income for the remainder of fiscal 2020. 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. The changes in the carrying amounts of goodwill for the three months ended April 5, 2020 are as follows (in thousands): BALANCE DECEMBER 30, 2019 ACQUISITIONS PURCHASE PRICE ACCOUNTING ADJUSTMENTS IMPAIRMENT FOREIGN CURRENCY TRANSLATION BALANCE APRIL 5, 2020 (In thousands) $ 257,439 $ — $ — $ (116,495 ) $ (3,024 ) $ 137,920 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 $81.8 million at April 5, 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 reporting 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 reporting segment for the reasons discussed, included below is selected information on our operating segments. Summary information by operating segment follows: AMERICAS EUROPE ASIA- PACIFIC TOTAL (In thousands) Three Months Ended April 5, 2020: Net Sales $ 158,091 $ 94,690 $ 35,388 $ 288,169 Depreciation and amortization 3,060 4,441 2,018 9,519 Total assets 679,777 530,101 166,391 1,376,269 Three Months Ended March 31, 2019: Net Sales $ 160,626 $ 93,050 $ 44,012 $ 297,688 Depreciation and amortization 3,251 4,680 2,132 10,063 A reconciliation of the Company’s total operating segment depreciation and amortization, and assets to the corresponding consolidated amounts follows: Three Months Ended DEPRECIATION AND AMORTIZATION April 5, 2020 March 31, 2019 (In thousands) Total segment depreciation and amortization $ 9,519 $ 10,063 Corporate depreciation and amortization 1,421 1,281 Reported depreciation and amortization $ 10,940 $ 11,344 ASSETS April 5, 2020 (In thousands) Total segment assets $ 1,376,269 Corporate assets 136,931 Eliminations (226,117 ) Reported total assets $ 1,287,083

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 three months ended April 5, 2020 , the Company recorded a total income tax provision of $1.5 million on a pre-tax loss of $100.6 million resulting in an effective tax rate of (1.5)% . 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 7.4% for the period compared to 17.7% during the three months ended March 31, 2019 . The decrease in the effective tax rate, excluding goodwill impairment, was due to the favorable impact of amending prior year tax returns which was partially offset by unfavorable changes related to company-owned life insurance. In the first three months of 2020 , the Company decreased its liability for unrecognized tax benefits by $0.8 million . As of April 5, 2020 , the Company had accrued approximately $24.7 million for unrecognized tax benefits. In accordance with applicable accounting standards, the Company’s deferred tax asset as of April 5, 2020 reflects a reduction for $2.8 million of these unrecognized tax benefits. Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including the progress of tax audits and the closing of statutes of limitations. Based on information currently available, it is reasonably possible that approximately $14.4 million of unrecognized tax benefits may be recognized within the next 12 months due to a lapse of statute of limitations. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES Act) was signed into law in response to the COVID-19 pandemic and provides certain tax relief to businesses. Tax provisions of the CARES Act include, among other things, the deferral of certain payroll taxes, relief for retaining employees, and certain income tax provisions for corporations. During the three months ended April 5, 2020 , the CARES Act did not have an impact on the Company’s effective tax rate or income tax accounts. While the Company continues to evaluate the impacts of the CARES Act and similar foreign government support programs on its business, it does not expect they will have a material impact during the year. The Company does expect to benefit from the deferral of certain payroll taxes which it believes will result in an increase in its payroll tax accrual of approximately $3.1 million through the end of fiscal year 2020.

Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment Charges	RESTRUCTURING CHARGES For the first quarter ended April 5, 2020 , the Company recorded a reduction of $1.1 million of previously recognized restructuring charges due to changes in expected cash payments and a postponed office lease exit. At April 5, 2020 , the total restructuring reserve was $8.4 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 is 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 Beginning of the Year Deductions 2020 Charged to Expenses 2020 Balance at April 5, 2020 (In thousands) Workforce Reduction $ 8,634 $ (981 ) $ (409 ) $ 7,244 Other Exit Costs 139 — — 139 Total $ 8,773 $ (981 ) $ (409 ) $ 7,383 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 include information technology assets and obsolete manufacturing equipment. As a result of this plan, the Company recorded a pre-tax restructuring and asset impairment charge in the fourth quarter of 2018 of approximately $20.5 million . The charge was comprised of severance expenses (approximately $10.8 million ), impairment of assets (approximately $8.6 million ) and other items (approximately $1.1 million ). The charge was expected to result in future cash expenditures of $12.0 million , primarily for severance payments (approximately $10.8 million ). The restructuring plan was substantially completed at the end of fiscal 2019. 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 Beginning of the Year Deductions 2020 Charged to Expenses 2020 Balance at (In thousands) Workforce Reduction $ 1,898 $ (929 ) $ (29 ) $ 940 Other Exit Costs 774 — (680 ) 94 Total $ 2,672 $ (929 ) $ (709 ) $ 1,034

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. 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.
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 impairment discussed in Note 10 “ Goodwill and Intangible Assets ” there were no other material adverse impacts on the Company’s results of operations and financial position at April 5, 2020 . Our 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. In the event we believe we are unable to maintain compliance with such covenants in the future, we will take mitigating actions prior to such potential breach. The full extent of the future impact of COVID-19 on the Company’s operations is uncertain. A prolonged COVID-19 pandemic could have a material adverse impact on our operations, financial condition, our ability to stay in compliance with our debt covenants, our ability to refinance our existing indebtedness and our ability to collect outstanding receivables. The impact of COVID-19 could also result in additional impairment losses related to goodwill, all 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 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 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 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 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.
New Accounting Pronouncements and Changes in Accounting Principles	Change in Accounting Principle In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Improvements to Share Based Payment Accounting,” to simplify the accounting for share based payment transactions. We previously adopted the provisions of this ASU in fiscal year 2017 and noted at that time that we would apply the policy election to estimate forfeitures of share based awards and reduce stock compensation expense based on that estimate. On December 30, 2019, the Company elected to change its forfeiture method related to share based awards and will now account for forfeitures as they occur, as allowed by ASU 2016-09. The Company believes that this change is preferable because it achieves better correlation of stock compensation expense with the requisite service period. The cumulative impact of this change did not have a material effect on the Company’s consolidated financial statements and is not expected to have a material effect on the full fiscal year 2020 consolidated financial statements. As a result, the cumulative effect of $1.4 million was recognized in selling, general and administrative expenses (“SG&A”) within the consolidated condensed statement of operations during the first quarter of fiscal year 2020 . Since the impact of this change is not material, prior period amounts were not retrospectively adjusted.
