Notes to Financial Statements
Significant Accounting Policies [Text Block]	1 Nature of Operations The Company is a recognized leader in the worldwide commercial interiors market, offering modular carpet, luxury vinyl tile (“LVT”) and rubber flooring products. The Company manufactures modular carpet focusing on the high quality, designer-oriented sector of the market, sources LVT from a third Intersept August 7, 2018. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. All of our subsidiaries are wholly-owned, and we are not Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Examples include provisions for returns, bad debts, product claims reserves, rebates, inventory obsolescence and the length of product life cycles, accruals associated with restructuring activities, income tax exposures and valuation allowances, environmental liabilities, and the carrying value of goodwill and property and equipment. Actual results could vary from these estimates. Revenue Recognition Effective January 1, 2018, 1 2 3 4 5 not Revenue Recognized from Contracts with Customers 100% 60 97% The remaining revenue generated by the Company is for contracts to sell and install carpet and related products at customer locations. For projects underway, the Company recognized installation revenue over time as the customer simultaneously received and consumed the benefit of the services. The installation of the carpet and related products is a separate performance obligation from the sale of carpet. The majority of these projects are completed within 5 The Company has utilized the portfolio approach to its contracts with customers, as its contracts with customers have similar characteristics and it is reasonable to expect that the effects from applying this approach are not The Company does not Performance Obligations As noted above, the Company primarily generates revenue through the sale of flooring material to end users either upon shipment or upon arrival of the product at its destination. In these instances, there typically is no not no 0.3% three no For the Company’s installation business, the sales of carpet and other flooring materials and installation services are separate deliverables which under the revenue recognition requirements should be characterized as separate performance obligations. The Company historically has not 90% 5 2018. Costs to Obtain Contracts The Company pays sales commissions to many of its sales personnel based upon their selling activity. These are direct costs associated with obtaining the contracts. Under the accounting standard, these costs should be expensed as the revenue is earned. As these commissions become payable upon shipment (or in certain cases delivery) of product, the commission is earned as the revenue is recognized. Due to this fact pattern, there is no no Prior to the adoption of the new revenue recognition model, the Company recognized revenue when the following criteria were met: persuasive evidence of an agreement exists, delivery has occurred or services have been rendered, price to the buyer is fixed and determinable, and collectability is reasonably assured. Delivery is not may Shipping and handling fees billed to customers are classified in net sales in the consolidated statements of operations. Shipping and handling costs incurred are classified in cost of sales in the consolidated statements of operations. Research and Development Research and development costs are expensed as incurred and are included in the selling, general and administrative expense caption in the consolidated statements of operations. Research and development expense was $16.4 $14.0 $14.3 2018, 2017 2016, Cash, Cash Equivalents and Short-Term Investments Highly liquid investments with insignificant interest rate risk and with original maturities of three three one not December 30, 2018 December 31, 2017. Cash payments for interest amounted to approximately $13.8 $6.3 $5.5 2018, 2017, 2016, $29.5 $19.1 $12.8 2018, 2017 2016, 2018, 2017 2016, $0.8 $0.1 $0.2 Inventories Inventories are carried at the lower of cost (standards approximating the first first may Management estimates its reserves for inventory obsolescence by continuously examining its inventories to determine if there are indicators that carrying values exceed net realizable values. Experience has shown that significant indicators that could require the need for additional inventory write-downs are the age of the inventory, the length of its product life cycles, anticipated demand for the Company’s products, and current economic conditions. While management believes that adequate write-downs for inventory obsolescence have been made in the consolidated financial statements, consumer tastes and preferences will continue to change and the Company could experience additional inventory write-downs in the future. Rebates The Company has agreements to receive cash consideration from certain of its vendors, including rebates and cooperative marketing reimbursements. The amounts received from its vendors are generally presumed to be a reduction of the prices the Company pays for their products and, therefore, such amounts are reflected as either a reduction of cost of sales in the accompanying consolidated statements of operations, or, if the product inventory is still on hand at the reporting date, it is reflected as a reduction of “Inventories” on the accompanying consolidated balance sheets. Vendor rebates are typically dependent upon reaching minimum purchase thresholds. The Company evaluates the likelihood of reaching purchase thresholds using past experience and current year forecasts. When rebates can be reasonably estimated and receipt becomes probable, the Company records a portion of the rebate as the Company makes progress towards the purchase threshold. When the Company receives direct reimbursements for costs incurred in marketing the vendor’s product or service, the amount received is recorded as an offset to selling, general and administrative expenses in the accompanying consolidated statements of operations. Assets and Liabilities of Businesses Held for Sale The Company considers businesses to be held for sale when the Board or management, having the relevant authority to do so, approves and commits to a formal plan to actively market a business for sale and the sale is considered probable. Upon designation as held for sale, the carrying value of the assets of the business are recorded at the lower of their carrying value or their estimated fair value, less costs to sell. The Company ceases to record depreciation expense at that time. Property and Equipment and Long-Lived Assets Property and equipment are carried at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: buildings and improvements – ten forty three twelve $0.7 $0.6 $0.5 2018, 2017 2016, $37.6 $29.5 $30.1 2018, 2017, 2016 Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not Goodwill and Other Intangible Assets Goodwill is the excess of the purchase price over the fair value of net assets acquired in business combinations accounted for as acquisitions. Accumulated amortization amounted to approximately $77.3 December 30, 2018 December 31, 2017, $212.6 December 30, 2018 December 31, 2017. In connection with the nora acquisition on August 7, 2018, $184.7 $103.3 $1.4 three None As of December 30, 2018, December 31, 2017, $245.8 $68.8 $97.7 $0.6 December 30, 2018 December 31, 2017, 2018, 2017 2016 $5.4 $0.7 $0.5 The Company capitalizes patent defense costs when it determines that a successful defense is probable. Any patent defense costs are amortized over the remaining useful life of the patent. During 2016, $3.4 TacTiles® no During the fourth 2018, 2017 2016, third one no Each of the Company’s reporting units maintained fair values in excess of their respective carrying values as of the measurement date, and therefore no December 30, 2018, 10% no The changes in the carrying amounts of goodwill for the year ended December 30, 2018 BALANCE JANUARY 1, 2018 ACQUISITIONS PURCHASE PRICE ACCOUNTING ADJUSTMENTS IMPAIRMENT FOREIGN CURRENCY TRANSLATION BALANCE DECEMBER 30, 2018 (in thousands) $ 68,754 $ 183,348 $ 1,377 $ 0 $ (7,664 ) $ 245,815 Product Warranties The Company typically provides limited warranties with respect to certain attributes of its carpet products (for example, warranties regarding excessive surface wear, edge ravel and static electricity) for periods ranging from ten twenty 5 15 one The Company records a provision related to warranty costs based on historical experience and periodically adjusts these provisions to reflect changes in actual experience. Warranty and sales allowance reserves amounted to $3.5 $4.1 December 30, 2018 December 31, 2017, Taxes on Income The Company accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments of changes in tax laws or rates. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets when it is more likely than not not The Company does not For uncertain tax positions, the Company applies the provisions of relevant authoritative guidance, which requires application of a “more likely than not” not 15 Fair Values of Financial Instruments Fair values of cash and cash equivalents and short-term debt approximate cost due to the short period of time to maturity. Fair values of debt are based on quoted market prices or pricing models using current market rates and classified as level 2 Translation of Foreign Currencies The financial position and results of operations of the Company’s foreign subsidiaries are measured using local currencies as the functional currency. Assets and liabilities of these subsidiaries are translated into U.S. dollars at the exchange rate in effect at each year-end. Income and expense items are translated at average exchange rates for the year. The resulting translation adjustments are recorded in the foreign currency translation adjustment account. In the event of a divestiture of a foreign subsidiary, the related foreign currency translation results are reversed from equity to income. Foreign currency exchange gains and losses are included in net income (loss). Foreign exchange translation gains (losses) were ( $22.5 $31.6 $19.0 2018, 2017 2016, Income (Loss) Per Share Basic income (loss) per share is computed based on the average number of common shares outstanding. Diluted income (loss) per share reflects the increase in average common shares outstanding that would result from the assumed exercise of outstanding stock options, calculated using the treasury stock method. Stock-Based Compensation The Company has stock-based employee compensation plans, which are described more fully in Note 12 The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model. However, there were no 2018, 2017 2016. The Company recognizes expense related to its restricted stock and performance share grants based on the grant date fair value of the shares awarded, as determined by its market price at date of grant. Derivative Financial Instruments Accounting standards require a company to recognize all derivatives on the balance sheet at fair value. Derivatives that do not 2017, 10 10 Pension Benefits Net pension expense recorded is based on, among other things, assumptions about the discount rate, estimated return on plan assets and salary increases. While the Company believes these assumptions are reasonable, changes in these and other factors and differences between actual and assumed changes in the present value of liabilities or assets of the Company’s plans above certain thresholds could cause net annual expense to increase or decrease materially from year to year. The actuarial assumptions used in the Company’s salary continuation plan and foreign defined benefit plans reporting are reviewed periodically and compared with external benchmarks to ensure that they appropriately account for our future pension benefit obligation. The expected long-term rate of return on plan assets assumption is based on weighted average expected returns for each asset class. Expected returns reflect a combination of historical performance analysis and the forward-looking views of the financial markets, and include input from actuaries, investment service firms and investment managers. Environmental Remediation The Company provides for remediation costs and penalties when the responsibility to remediate is probable and the amount of associated costs is reasonably determinable. Remediation liabilities are accrued based on estimates of known environmental exposures and are discounted in certain instances. The Company regularly monitors the progress of environmental remediation. Should studies indicate that the cost of remediation is to be more than previously estimated, an additional accrual would be recorded in the period in which such determination is made. As of December 30, 2018, December 31, 2017, no Allowances for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. Estimating this amount requires the Company to analyze the financial strengths of its customers. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may may Reclassifications Certain prior period amounts have been reclassified to conform to current year financial statement presentation.

Collateral Pursuant to an Amended and Restated Security and Pledge Agreement executed on the same date, the Facility is secured by substantially all of the assets of the Company and its domestic subsidiaries (subject to exceptions for certain immaterial subsidiaries), including all of the stock of the Company’s domestic subsidiaries and up to 65% first may, first As of December 30, 2018, $616.1 $10.6 $3.6 December 30, 2018, 3.50%. Under the amended and restated Facility, the Company is required to make quarterly amortization payments of the term loan borrowings, which commenced in the fourth 2018. 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. Interest Rate Risk Management Shortly after entering into the Amended and Restated Facility Agreement, the Company entered into an interest rate swap transaction to fix the variable interest rate on a portion of its term loan borrowings in order to manage a portion of its exposure to interest rate fluctuations. The Company’s objective and strategy with respect to this interest rate swap 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 amount. Cash Flow Interest Rate Swap The Company’s interest rate swap is designated and qualifies as a cash flow hedge of forecasted interest payments. The Company reports the effective portion of the fair value gain or loss on the swap as a component of other comprehensive income (or other comprehensive loss). Gains or losses (if any) on any ineffective portion of derivative instruments in cash flow hedging relationships are recorded in the period in which they occur as a component of other expense (or other income) in the consolidated statement of operations.

The Company reports the effective portion of the fair value gain or loss on the swap as a component of other comprehensive income (or other comprehensive loss). Gains or losses (if any) on any ineffective portion of derivative instruments in cash flow hedging relationships are recorded in the period in which they occur as a component of other expense (or other income) in the Consolidated Statement of Operations and as a component of operating activities in the Consolidated Statement of Cash Flows. The aggregate notional amount of the swap as of December 30, 2018 $100 Forward Contracts The recently acquired nora operations 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. The Company is meeting its objective by hedging the risk of changes in its cash flows (intercompany payments for inventory) attributable to changes in the U.S. dollar/Euro exchange rate (the “hedged risk”). Changes in fair value attributable to components other than exchange rates will be excluded from the assessment of effectiveness and amortized to earnings on a straight-line basis. Changes in fair value related to the effective portion of these contracts will be reflected as a component of other comprehensive income (or other comprehensive loss).

Earnings Per Share [Text Block]	NOTE 1 3 – INCOME (LOSS) PER SHARE The Company computes basic earnings (loss) per share (“EPS”) by dividing net income (loss), by the weighted average common shares outstanding, including participating securities outstanding, during the period as depicted 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. Income attributable to non-controlling interest is included in the computation of basic and diluted earnings per share, where applicable. 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 common 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.

Expected returns reflect a combination of historical performance analysis and the forward-looking views of the financial markets, and include input from actuaries, investment service firms and investment managers. The investment objectives of the foreign defined benefit plans are to maximize the return on the investments without exceeding the limits of the prudent pension fund investment, to ensure that the assets would be sufficient to exceed minimum funding requirements, and to achieve a favorable return against the performance expectation based on historic and projected rates of return over the short term. The goal is to optimize the long-term return on plan assets at a moderate level of risk, by balancing higher-returning assets, such as equity securities, with less volatile assets, such as fixed income securities.

Dutch Plan Assets and Indexation Benefit As is common in Dutch pension plans, the Dutch Plan includes a provision for discretionary benefit increases termed “indexation.” The indexation benefit is meant to adjust pension benefits for cost-of-living increases, similar to U.S. consumer price index-based cost-of-living adjustments for U.S. retirement plans. The indexation benefit is not Both the vested benefit amounts as well as amounts related to the discretionary indexation benefits under the Dutch Plan are paid pursuant to an insurance contract with a private insurer (the “Contract”). The Plan itself is financed by investment assets held within the Contract. The Contract guarantees payment of vested amounts, regardless of whether Plan assets held through the Contract are ultimately sufficient to pay vested amounts, and also provides for payment of the indexation amount on a contingent basis if the actual return on Dutch Plan assets is sufficient to pay it. This type of insurance arrangement is common in The Netherlands, although not Because the prior actual and future projected returns on Dutch Plan assets had been determined to be sufficient to provide for the indexation benefit, in 2017 2016, 2018, not not 2018.

Level 2 Inputs to the valuation methodology include: ● quoted prices for similar assets in active markets; ● quoted prices for identical or similar assets in inactive markets; ● inputs other than quoted prices that are observable for the asset; and ● inputs that are derived principally or corroborated by observable data by correlation or other means. Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Examples include provisions for returns, bad debts, product claims reserves, rebates, inventory obsolescence and the length of product life cycles, accruals associated with restructuring activities, income tax exposures and valuation allowances, environmental liabilities, and the carrying value of goodwill and property and equipment. Actual results could vary from these estimates.

These are direct costs associated with obtaining the contracts. Under the accounting standard, these costs should be expensed as the revenue is earned.

Due to this fact pattern, there is no no Prior to the adoption of the new revenue recognition model, the Company recognized revenue when the following criteria were met: persuasive evidence of an agreement exists, delivery has occurred or services have been rendered, price to the buyer is fixed and determinable, and collectability is reasonably assured.

Experience has shown that significant indicators that could require the need for additional inventory write-downs are the age of the inventory, the length of its product life cycles, anticipated demand for the Company’s products, and current economic conditions. While management believes that adequate write-downs for inventory obsolescence have been made in the consolidated financial statements, consumer tastes and preferences will continue to change and the Company could experience additional inventory write-downs in the future.
Accrued Sales Rebates [Policy Text Block]	Rebates The Company has agreements to receive cash consideration from certain of its vendors, including rebates and cooperative marketing reimbursements. The amounts received from its vendors are generally presumed to be a reduction of the prices the Company pays for their products and, therefore, such amounts are reflected as either a reduction of cost of sales in the accompanying consolidated statements of operations, or, if the product inventory is still on hand at the reporting date, it is reflected as a reduction of “Inventories” on the accompanying consolidated balance sheets. Vendor rebates are typically dependent upon reaching minimum purchase thresholds. The Company evaluates the likelihood of reaching purchase thresholds using past experience and current year forecasts. When rebates can be reasonably estimated and receipt becomes probable, the Company records a portion of the rebate as the Company makes progress towards the purchase threshold. When the Company receives direct reimbursements for costs incurred in marketing the vendor’s product or service, the amount received is recorded as an offset to selling, general and administrative expenses in the accompanying consolidated statements of operations.
Discontinued Operations, Policy [Policy Text Block]	Assets and Liabilities of Businesses Held for Sale The Company considers businesses to be held for sale when the Board or management, having the relevant authority to do so, approves and commits to a formal plan to actively market a business for sale and the sale is considered probable. Upon designation as held for sale, the carrying value of the assets of the business are recorded at the lower of their carrying value or their estimated fair value, less costs to sell. The Company ceases to record depreciation expense at that time.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment and Long-Lived Assets Property and equipment are carried at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: buildings and improvements – ten forty three twelve $0.7 $0.6 $0.5 2018, 2017 2016, $37.6 $29.5 $30.1 2018, 2017, 2016 Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets Goodwill is the excess of the purchase price over the fair value of net assets acquired in business combinations accounted for as acquisitions.

Warranty and sales allowance reserves amounted to $3.5 $4.1 December 30, 2018 December 31, 2017,
Income Tax, Policy [Policy Text Block]	Taxes on Income The Company accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments of changes in tax laws or rates. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets when it is more likely than not not The Company does not For uncertain tax positions, the Company applies the provisions of relevant authoritative guidance, which requires application of a “more likely than not” not 15
Fair Value Measurement, Policy [Policy Text Block]	Fair Values of Financial Instruments Fair values of cash and cash equivalents and short-term debt approximate cost due to the short period of time to maturity. Fair values of debt are based on quoted market prices or pricing models using current market rates and classified as level 2
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation of Foreign Currencies The financial position and results of operations of the Company’s foreign subsidiaries are measured using local currencies as the functional currency. Assets and liabilities of these subsidiaries are translated into U.S. dollars at the exchange rate in effect at each year-end. Income and expense items are translated at average exchange rates for the year. The resulting translation adjustments are recorded in the foreign currency translation adjustment account. In the event of a divestiture of a foreign subsidiary, the related foreign currency translation results are reversed from equity to income. Foreign currency exchange gains and losses are included in net income (loss). Foreign exchange translation gains (losses) were ( $22.5 $31.6 $19.0 2018, 2017 2016,
Earnings Per Share, Policy [Policy Text Block]	Income (Loss) Per Share Basic income (loss) per share is computed based on the average number of common shares outstanding. Diluted income (loss) per share reflects the increase in average common shares outstanding that would result from the assumed exercise of outstanding stock options, calculated using the treasury stock method.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation The Company has stock-based employee compensation plans, which are described more fully in Note 12 The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model. However, there were no 2018, 2017 2016.

Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments Accounting standards require a company to recognize all derivatives on the balance sheet at fair value. Derivatives that do not 2017, 10 10
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Pension Benefits Net pension expense recorded is based on, among other things, assumptions about the discount rate, estimated return on plan assets and salary increases. While the Company believes these assumptions are reasonable, changes in these and other factors and differences between actual and assumed changes in the present value of liabilities or assets of the Company’s plans above certain thresholds could cause net annual expense to increase or decrease materially from year to year. The actuarial assumptions used in the Company’s salary continuation plan and foreign defined benefit plans reporting are reviewed periodically and compared with external benchmarks to ensure that they appropriately account for our future pension benefit obligation. The expected long-term rate of return on plan assets assumption is based on weighted average expected returns for each asset class. Expected returns reflect a combination of historical performance analysis and the forward-looking views of the financial markets, and include input from actuaries, investment service firms and investment managers.
Environmental Costs, Policy [Policy Text Block]	Environmental Remediation The Company provides for remediation costs and penalties when the responsibility to remediate is probable and the amount of associated costs is reasonably determinable. Remediation liabilities are accrued based on estimates of known environmental exposures and are discounted in certain instances. The Company regularly monitors the progress of environmental remediation. Should studies indicate that the cost of remediation is to be more than previously estimated, an additional accrual would be recorded in the period in which such determination is made. As of December 30, 2018, December 31, 2017, no
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Allowances for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. Estimating this amount requires the Company to analyze the financial strengths of its customers. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may may
