Accounting Policies [Abstract]
Principles of Consolidation	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 a party to any joint venture, partnership or other variable interest entity that would potentially qualify for consolidation. All material intercompany accounts and transactions are eliminated.
Use of Estimates	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	Revenue Recognition Effective January 1, 2018, the Company adopted a new accounting standard with regard to revenue from customers. The core principle of this standard is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, the guidance provides that an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. The Company elected the modified retrospective approach for adoption of this new standard, as is allowed by the standard. The Company did not have any significant impact from this standard as of the date of the adoption. Revenue Recognized from Contracts with Customers Contracts with customers typically take the form of invoices for purchase of materials from the Company. Customer payment terms vary by region and are typically less than 60 days. The performance obligation is the delivery of these materials to the customer’s control. During 2019 and 2018, approximately 98% and 97% of the Company’s total revenue, respectively, was produced from the sale of carpet, resilient flooring, rubber flooring, and related products (TacTiles installation materials, etc.) and the revenue from sales of these products is recognized upon shipment, or in certain cases, upon delivery to the customer. The transaction price for these sales is readily identifiable. The remaining revenue for 2019 and 2018 of 2% and 3%, respectively, was generated from the installation of carpet and other flooring-related material. 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 days of the start of installation. The transaction price for these sale and installation contracts is readily determinable between flooring material and installation services and is specifically identified in the contract with the customer. 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 materially different from applying the accounting standard to individual contracts. The Company does not have any other significant revenue streams outside of these sales of flooring material, and the sale and installation of flooring material, as described above. The Company does not record taxes collected from customers and remitted to governmental authorities on a gross basis. 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 other obligation to the customers other than the delivery of flooring material with the exception of warranty. The Company does offer a warranty to its customers which guarantees certain on-floor performance characteristics and warrants against manufacturing defects. The warranty is not a service warranty, and there is no ability to separate the warranty obligation from the sale of the flooring or purchase them separately. The Company’s incidence of warranty claims is extremely low, with less than 0.5% of revenue in claims on an annual basis for the last three fiscal years. Given the nature of the warranty as well as the financial impact, the Company has determined that there is no need to identify this warranty as a separate performance obligation and the Company will continue to account for warranty on an accrual basis. 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. Prior to the adoption of the new accounting standard, the Company historically had not separated these obligations and had accounted for these installation projects on a completed contract basis. The nature of the installation projects is such that the vast majority – an amount in excess of 90% of these installation projects – are completed in less than 5 days. The Company’s largest installation customers are retail and corporate customers, and these are on a project-by-project basis and are short-term installations. The Company has evaluated these projects at the end of the reporting period and recorded revenue in accordance with the accounting standards for projects which were underway as of the end of 2019. 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 and are 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. There are no other material costs the Company incurs as part of obtaining the sales contract. Shipping and Handling 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 Research and development costs are expensed as incurred and are included in selling, general and administrative expenses and cost of sales in the consolidated statements of operations.
Cash, Cash Equivalents and Short-Term Investments	Cash, Cash Equivalents and Short-Term Investments Highly liquid investments with insignificant interest rate risk and with original maturities of three months or less are classified as cash and cash equivalents. Investments with maturities greater than three months and less than one year are classified as short-term investments. Significant concentrations of credit risk may arise from the Company’s cash maintained at various banks, as from time to time cash balances may exceed the FDIC limits.
Inventories	Inventories Inventories are carried at the lower of cost (standards approximating the first-in, first-out method) or net realizable value. Costs included in inventories are based on invoiced costs and/or production costs, as applicable. Included in production costs are material, direct labor and allocated overhead. The Company writes down inventories for the difference between the carrying value of the inventories and their estimated net realizable value. If actual market conditions are less favorable than those projected by management, additional write-downs may be required. 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	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.
Leases	Leases 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, which is based on the estimated rate for a fully collateralized borrowing that fully amortizes over a similar lease term at the commencement date and for the applicable geographical region. We 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 sheet. 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. We also made an accounting policy election not to separate lease and non-lease components for all asset classes and will account for the lease payments as a single component.
Property and Equipment and Long-Lived Assets	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 to forty years; and furniture and equipment – three to twelve years. Interest costs for the construction/development of certain long-term assets are capitalized and amortized over the related assets’ estimated useful lives. The Company capitalized net interest costs on qualifying expenditures of approximately $2.1 million, $0.7 million, and $0.6 million for the fiscal years 2019, 2018 and 2017, respectively. Depreciation expense amounted to approximately $41.5 million, $37.6 million, and $29.5 million for the years 2019, 2018, and 2017 respectively. Depreciation expense recorded to costs of sales in the consolidated statements of operations was $26.3 million, $21.8 million, and $14.8 million for the years 2019, 2018, and 2017, respectively. Depreciation expense recorded in SG&A expenses in the consolidated statements of operations was $15.2 million, $15.8 million, and $14.7 million, for the years 2019, 2018, and 2017, respectively. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flow is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and carrying value of the asset. Repair and maintenance costs are charged to operating expense as incurred.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets In connection with the nora acquisition on August 7, 2018, the Company recognized goodwill of $201.9 million and acquired intangible assets of $103.3 million. Goodwill includes all purchase price accounting adjustments of approximately $18.6 million related to additional liabilities that existed at the acquisition date. Goodwill and intangible assets were assigned pro-rata to the Company’s three operating segments. None of the goodwill is expected to be deductible for income tax purposes. As of December 29, 2019, and December 30, 2018, the net carrying amount of goodwill was $257.4 million and $245.8 million, respectively. Other intangible assets were $89.1 million and $97.7 million as of December 29, 2019 and December 30, 2018, respectively. Amortization expense related to intangible assets during the years 2019, 2018 and 2017 was $5.9 million, $5.4 million and $0.7 million, respectively and are recorded in cost of sales in the consolidated statements of operations. During the fourth quarters of 2019, 2018 and 2017, as of the last day of the third quarter of each year, the Company performed the annual goodwill impairment test. The Company performs this test at the reporting unit level, which is one level below the segment level for the Flooring segment. In performing the 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. In preparing the valuations, past, present and future expectations of performance were considered. The annual testing indicated no potential of goodwill impairment in any of the years presented. 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 impairment was indicated as a result of the impairment testing. As of December 29, 2019, if the Company’s estimates of the fair values of its reporting units which carry a goodwill balance were 10% lower, the Company still believes no goodwill impairment would have existed.
Product Warranties	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 to twenty years, depending on the particular carpet product and the environment in which it is to be installed. Similar limited warranties are provided on certain attributes of its rubber and LVT products, typically for a period of 5 to 15 years. The Company typically warrants that services performed will be free from defects in workmanship for a period of one year following completion. In the event of a breach of warranty, the remedy typically is limited to repair of the problem or replacement of the affected product. 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 $3.9 million and $3.5 million as of December 29, 2019 and December 30, 2018, respectively, and are included in “Accrued Expenses” in the accompanying consolidated balance sheets.
Income Taxes	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 that some portion or all of the deferred tax assets will expire before realization of the benefit or that future deductibility is not probable. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future. This requires us to use estimates and make assumptions regarding significant future events such as the taxability of entities operating in the various taxing jurisdictions. For uncertain tax positions, the Company applies the provisions of relevant authoritative guidance, which requires application of a “more likely than not” threshold to the recognition and derecognition of tax positions. The Company’s ongoing assessments of the more likely than not outcomes of tax authority examinations and related tax positions require significant judgment and can increase or decrease the Company’s effective tax rate as well as impact operating results. For further information, see Note 16 entitled “Income Taxes.”
Fair Values of Financial Instruments	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 within the fair value hierarchy.
Translation of Foreign Currencies	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.
Earnings Per Share	Basic earnings per share is computed based on the average number of common shares outstanding. Diluted earnings 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	Stock-Based Compensation The Company has stock-based employee compensation plans, which are described more fully in Note 13 entitled “Shareholders' Equity.” 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 stock options granted in 2019, 2018 or 2017. 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	Derivative Financial Instruments Derivatives are recognized on the balance sheet at fair value. For derivatives that meet the criteria as designated cash flow hedges, the effective portion of changes in the fair value of the derivative are recognized in other comprehensive income until the hedged item is recognized in earnings. Derivative liabilities are recorded in accrued expenses and derivative assets are recorded in other current assets in the consolidated balance sheet.
Pension Benefits	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.
Allowances for Doubtful Accounts	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 be required. By its nature, such an estimate is highly subjective, and it is possible that the amount of accounts receivable that the Company is unable to collect may be different than the amount initially estimated.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to current year financial statement presentation. These reclassifications had no effect on reported income, comprehensive income, cash flows, or shareholders’ equity as previously reported.
Fiscal Year	Fiscal Year The Company’s fiscal year is the 52 or 53 week period ending on the Sunday nearest December 31. All references herein to “2019,” “2018,” and “2017,” mean the fiscal years ended December 29, 2019, December 30, 2018, and December 31, 2017, respectively. Fiscal years 2019, 2018 and 2017 were each comprised of 52 weeks.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On December 31, 2018, the Company adopted Accounting Standards Codification (“ASC”) Topic 842, “Leases.” The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The Company adopted the new lease standard using the modified retrospective approach and recorded operating lease right-of-use assets and operating lease liabilities for approximately $115.0 million respectively, with no cumulative-effect adjustment to retained earnings. The Company elected to apply the practical expedients allowed by the standard, which resulted in the Company not having to reassess whether expired or existing contracts contained a lease as well as retaining the historical classification of our leases. The Company also elected the hindsight practical expedient in evaluating lessee options and elected to combine lease and non-lease components in calculating the right-of-use asset and lease liability for all leases, except data center assets. See Note 11 entitled “Leases” for additional information. On December 31, 208 the Company adopted, Accounting Standards Update (“ASU”) 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which addresses a narrow-scope financial reporting issue that arose as a consequence of the U.S. Tax Cuts and Jobs Act. The former guidance required that deferred tax liabilities and assets be adjusted for a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance was applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income (rather than in net income), such as amounts related to benefit plans and hedging activity. As a result, the tax effects of items within accumulated other comprehensive income do not reflect the appropriate tax rate (the difference is referred to as stranded tax effects). The new guidance allows for a reclassification of these amounts to retained earnings, thereby eliminating these stranded tax effects. The adoption of this standard did not have a material effect on the Company’s consolidated financial statements as the Company did not elect to reclassify stranded tax effects into retained earnings. On December 31, 2018, the Company adopted ASU 2018-07, “Improvements to Nonemployee Share-Based Payment Accounting.” This standard requires that the accounting treatment for non-employee share-based payments for goods or services be consistent with current accounting for employee share-based payments, including measurement of awards at grant-date fair value and the application of probability to evaluate performance conditions. This standard also eliminates the current GAAP requirement to reassess the classification of non-employee share-based payments awards upon vesting. The adoption of this standard did not have a material effect on 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. The amendments also improve consistent application of and simplify GAAP for other areas of ASC Topic 740 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 August 2018, the FASB issued 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 new guidance is effective for interim and annual periods beginning after December 15, 2019. The Company does not anticipate that the adoption of the new standard will have a material effect on its consolidated financial statements. In August 2018, the FASB issued 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 new guidance is effective for interim and annual periods beginning after December 15, 2019. 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 December 2017, the FASB issued 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. The new guidance is effective for any annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company does not anticipate that the adoption of the new standard will have a material effect on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13 “Financial Instruments -- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU 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. This standard is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. The new standard provides both a modified retrospective or prospective adoption method. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements, due to the short-term nature of its trade accounts receivable.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 29, 2019

The consolidated financial statements include the accounts of the Company and its subsidiaries. All of our subsidiaries are wholly-owned, and we are not a party to any joint venture, partnership or other variable interest entity that would potentially qualify for consolidation. All material intercompany accounts and transactions are eliminated.

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, the Company adopted a new accounting standard with regard to revenue from customers. The core principle of this standard is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, the guidance provides that an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. The Company elected the modified retrospective approach for adoption of this new standard, as is allowed by the standard. The Company did not have any significant impact from this standard as of the date of the adoption.

Revenue Recognized from Contracts with Customers

Contracts with customers typically take the form of invoices for purchase of materials from the Company. Customer payment terms vary by region and are typically less than 60 days. The performance obligation is the delivery of these materials to the customer’s control. During 2019 and 2018, approximately 98% and 97% of the Company’s total revenue, respectively, was produced from the sale of carpet, resilient flooring, rubber flooring, and related products (TacTiles installation materials, etc.) and the revenue from sales of these products is recognized upon shipment, or in certain cases, upon delivery to the customer. The transaction price for these sales is readily identifiable. The remaining revenue for 2019 and 2018 of 2% and 3%, respectively, was generated from the installation of carpet and other flooring-related material.

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 days of the start of installation. The transaction price for these sale and installation contracts is readily determinable between flooring material and installation services and is specifically identified in the contract with the customer.

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 materially different from applying the accounting standard to individual contracts.

The Company does not have any other significant revenue streams outside of these sales of flooring material, and the sale and installation of flooring material, as described above.

The Company does not record taxes collected from customers and remitted to governmental authorities on a gross basis.

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 other obligation to the customers other than the delivery of flooring material with the exception of warranty. The Company does offer a warranty to its customers which guarantees certain on-floor performance characteristics and warrants against manufacturing defects. The warranty is not a service warranty, and there is no ability to separate the warranty obligation from the sale of the flooring or purchase them separately. The Company’s incidence of warranty claims is extremely low, with less than 0.5% of revenue in claims on an annual basis for the last three fiscal years. Given the nature of the warranty as well as the financial impact, the Company has determined that there is no need to identify this warranty as a separate performance obligation and the Company will continue to account for warranty on an accrual basis.

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. Prior to the adoption of the new accounting standard, the Company historically had not separated these obligations and had accounted for these installation projects on a completed contract basis. The nature of the installation projects is such that the vast majority – an amount in excess of 90% of these installation projects – are completed in less than 5 days. The Company’s largest installation customers are retail and corporate customers, and these are on a project-by-project basis and are short-term installations. The Company has evaluated these projects at the end of the reporting period and recorded revenue in accordance with the accounting standards for projects which were underway as of the end of 2019.

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 and are 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. There are no other material costs the Company incurs as part of obtaining the sales contract.

Shipping and Handling

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 selling, general and administrative expenses and cost of sales in the consolidated statements of operations.

Cash, Cash Equivalents and Short-Term Investments

Highly liquid investments with insignificant interest rate risk and with original maturities of three months or less are classified as cash and cash equivalents. Investments with maturities greater than three months and less than one year are classified as short-term investments. Significant concentrations of credit risk may arise from the Company’s cash maintained at various banks, as from time to time cash balances may exceed the FDIC limits.

Inventories

Inventories are carried at the lower of cost (standards approximating the first-in, first-out method) or net realizable value. Costs included in inventories are based on invoiced costs and/or production costs, as applicable. Included in production costs are material, direct labor and allocated overhead. The Company writes down inventories for the difference between the carrying value of the inventories and their estimated net realizable value. If actual market conditions are less favorable than those projected by management, additional write-downs may be required.

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.

Leases

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, which is based on the estimated rate for a fully collateralized borrowing that fully amortizes over a similar lease term at the commencement date and for the applicable geographical region.

We 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 sheet. 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. We also made an accounting policy election not to separate lease and non-lease components for all asset classes and will account for the lease payments as a single component.

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 to forty years; and furniture and equipment – three to twelve years. Interest costs for the construction/development of certain long-term assets are capitalized and amortized over the related assets’ estimated useful lives. The Company capitalized net interest costs on qualifying expenditures of approximately $2.1 million, $0.7 million, and $0.6 million for the fiscal years 2019, 2018 and 2017, respectively. Depreciation expense amounted to approximately $41.5 million, $37.6 million, and $29.5 million for the years 2019, 2018, and 2017 respectively. Depreciation expense recorded to costs of sales in the consolidated statements of operations was $26.3 million, $21.8 million, and $14.8 million for the years 2019, 2018, and 2017, respectively. Depreciation expense recorded in SG&A expenses in the consolidated statements of operations was $15.2 million, $15.8 million, and $14.7 million, for the years 2019, 2018, and 2017, respectively.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flow is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and carrying value of the asset. Repair and maintenance costs are charged to operating expense as incurred.

Goodwill and Other Intangible Assets

In connection with the nora acquisition on August 7, 2018, the Company recognized goodwill of $201.9 million and acquired intangible assets of $103.3 million. Goodwill includes all purchase price accounting adjustments of approximately $18.6 million related to additional liabilities that existed at the acquisition date. Goodwill and intangible assets were assigned pro-rata to the Company’s three operating segments. None of the goodwill is expected to be deductible for income tax purposes.

As of December 29, 2019, and December 30, 2018, the net carrying amount of goodwill was $257.4 million and $245.8 million, respectively. Other intangible assets were $89.1 million and $97.7 million as of December 29, 2019 and December 30, 2018, respectively. Amortization expense related to intangible assets during the years 2019, 2018 and 2017 was $5.9 million, $5.4 million and $0.7 million, respectively and are recorded in cost of sales in the consolidated statements of operations.

During the fourth quarters of 2019, 2018 and 2017, as of the last day of the third quarter of each year, the Company performed the annual goodwill impairment test. The Company performs this test at the reporting unit level, which is one level below the segment level for the Flooring segment. In performing the 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. In preparing the valuations, past, present and future expectations of performance were considered. The annual testing indicated no potential of goodwill impairment in any of the years presented.

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 impairment was indicated as a result of the impairment testing. As of December 29, 2019, if the Company’s estimates of the fair values of its reporting units which carry a goodwill balance were 10% lower, the Company still believes no goodwill impairment would have existed.

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 to twenty years, depending on the particular carpet product and the environment in which it is to be installed. Similar limited warranties are provided on certain attributes of its rubber and LVT products, typically for a period of 5 to 15 years. The Company typically warrants that services performed will be free from defects in workmanship for a period of one year following completion. In the event of a breach of warranty, the remedy typically is limited to repair of the problem or replacement of the affected product.

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 $3.9 million and $3.5 million as of December 29, 2019 and December 30, 2018, respectively, and are included in “Accrued Expenses” in the accompanying consolidated balance sheets.

Income Taxes

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 that some portion or all of the deferred tax assets will expire before realization of the benefit or that future deductibility is not probable. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future. This requires us to use estimates and make assumptions regarding significant future events such as the taxability of entities operating in the various taxing jurisdictions.

For uncertain tax positions, the Company applies the provisions of relevant authoritative guidance, which requires application of a “more likely than not” threshold to the recognition and derecognition of tax positions. The Company’s ongoing assessments of the more likely than not outcomes of tax authority examinations and related tax positions require significant judgment and can increase or decrease the Company’s effective tax rate as well as impact operating results. For further information, see Note 16 entitled “Income Taxes.”

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 within the fair value hierarchy.

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.

Earnings Per Share

Basic earnings per share is computed based on the average number of common shares outstanding. Diluted earnings 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 13 entitled “Shareholders' Equity.”

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 stock options granted in 2019, 2018 or 2017.

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

Derivatives are recognized on the balance sheet at fair value. For derivatives that meet the criteria as designated cash flow hedges, the effective portion of changes in the fair value of the derivative are recognized in other comprehensive income until the hedged item is recognized in earnings. Derivative liabilities are recorded in accrued expenses and derivative assets are recorded in other current assets in the consolidated balance sheet.

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.

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 be required. By its nature, such an estimate is highly subjective, and it is possible that the amount of accounts receivable that the Company is unable to collect may be different than the amount initially estimated.

Reclassifications

Certain prior period amounts have been reclassified to conform to current year financial statement presentation. These reclassifications had no effect on reported income, comprehensive income, cash flows, or shareholders’ equity as previously reported.

Fiscal Year

The Company’s fiscal year is the 52 or 53 week period ending on the Sunday nearest December 31. All references herein to “2019,” “2018,” and “2017,” mean the fiscal years ended December 29, 2019, December 30, 2018, and December 31, 2017, respectively. Fiscal years 2019, 2018 and 2017 were each comprised of 52 weeks.

Recently Adopted Accounting Pronouncements

On December 31, 2018, the Company adopted Accounting Standards Codification (“ASC”) Topic 842, “Leases.” The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The Company adopted the new lease standard using the modified retrospective approach and recorded operating lease right-of-use assets and operating lease liabilities for approximately $115.0 million respectively, with no cumulative-effect adjustment to retained earnings. The Company elected to apply the practical expedients allowed by the standard, which resulted in the Company not having to reassess whether expired or existing contracts contained a lease as well as retaining the historical classification of our leases. The Company also elected the hindsight practical expedient in evaluating lessee options and elected to combine lease and non-lease components in calculating the right-of-use asset and lease liability for all leases, except data center assets. See Note 11 entitled “Leases” for additional information.

On December 31, 208 the Company adopted, Accounting Standards Update (“ASU”) 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which addresses a narrow-scope financial reporting issue that arose as a consequence of the U.S. Tax Cuts and Jobs Act. The former guidance required that deferred tax liabilities and assets be adjusted for a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance was applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income (rather than in net income), such as amounts related to benefit plans and hedging activity. As a result, the tax effects of items within accumulated other comprehensive income do not reflect the appropriate tax rate (the difference is referred to as stranded tax effects). The new guidance allows for a reclassification of these amounts to retained earnings, thereby eliminating these stranded tax effects. The adoption of this standard did not have a material effect on the Company’s consolidated financial statements as the Company did not elect to reclassify stranded tax effects into retained earnings.

On December 31, 2018, the Company adopted ASU 2018-07, “Improvements to Nonemployee Share-Based Payment Accounting.” This standard requires that the accounting treatment for non-employee share-based payments for goods or services be consistent with current accounting for employee share-based payments, including measurement of awards at grant-date fair value and the application of probability to evaluate performance conditions. This standard also eliminates the current GAAP requirement to reassess the classification of non-employee share-based payments awards upon vesting. The adoption of this standard did not have a material effect on 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. The amendments also improve consistent application of and simplify GAAP for other areas of ASC Topic 740 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 August 2018, the FASB issued 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 new guidance is effective for interim and annual periods beginning after December 15, 2019. The Company does not anticipate that the adoption of the new standard will have a material effect on its consolidated financial statements.

In August 2018, the FASB issued 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 new guidance is effective for interim and annual periods beginning after December 15, 2019. 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 December 2017, the FASB issued 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. The new guidance is effective for any annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company does not anticipate that the adoption of the new standard will have a material effect on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments -- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU 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. This standard is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. The new standard provides both a modified retrospective or prospective adoption method. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements, due to the short-term nature of its trade accounts receivable.
