Accounting Policies [Abstract]
General	General Interim Reporting The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and do not include all of the information and footnotes required by U.S. generally accepted accounting principles ("U.S. GAAP") for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the consolidated financial statements and notes thereto, and the Company’s description of critical accounting policies, included in the Company’s 2015 Annual Report on Form 10-K, as filed with the Securities and Exchange Commission. Results for interim periods are not necessarily indicative of the results for the year. Segment Realignment During the second quarter of 2015, the Company realigned its reportable segments to reflect how the Company’s results will be reported by management. The Company has reorganized the business into three segments - Global Ceramic, Flooring North America ("Flooring NA") and Flooring Rest of the World ("Flooring ROW"). In order to leverage its relationships and distribution capabilities, the Company organized its carpet, wood, laminate, luxury vinyl tile ("LVT") and vinyl operations by geography into the Flooring NA segment and Flooring ROW segment. The Company did not make any changes to the Global Ceramic segment, which includes the Company's tile and stone operations. Previously reported segment results have been reclassified to conform to the current period presentation. This new segment structure is consistent with the strategic objective that management now applies to manage the growth and profitability of the Company’s business. The Global Ceramic segment includes all worldwide tile and natural stone operations. The Flooring NA segment includes North American operations in all product categories except tile and natural stone. The new segment combines the former Carpet segment with the North American operations of the former Laminate and Wood segment and the North American operations of the Company’s newly acquired vinyl flooring businesses. The Flooring ROW segment includes operations outside of North America in all product categories except tile and natural stone. The new segment combines the European and Rest of the World operations of the former Laminate and Wood segment and the European and Rest of the World operations of the Company’s newly acquired vinyl flooring businesses. Hedges of Net Investments in Non-U.S. Operations The Company has numerous investments outside the United States. The net assets of these subsidiaries are exposed to changes and volatility in currency exchange rates. The Company uses foreign currency denominated debt to hedge some of its non-U.S. net investments against adverse movements in exchange rates. The gains and losses on the Company's net investments in its non-U.S. operations are partially economically offset by losses and gains on its foreign currency borrowings. The Company designated its €500,000 2.00% Senior Notes borrowing as a net investment hedge of a portion of its European operations. For the six months ended July 2, 2016, the change in the U.S. dollar value of the Company's euro denominated debt was a decrease of $7,674 ($4,796 net of taxes), which is recorded in the foreign currency translation adjustment component of other comprehensive income (loss). The decrease in the U.S. dollar value of the Company's debt partially offsets the euro-to-dollar translation of the Company's net investment in its European operations. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers. This topic converges the guidance within U.S. GAAP and International Financial Reporting Standards ("IFRS") and supersedes ASC 605, Revenue Recognition. The new standard requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance for multiple-element arrangements. The new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period and early application is not permitted. On July 9, 2015, the FASB decided to defer the effective date of ASC 606 for one year. The deferral results in the new revenue standard being effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company currently plans to adopt the provisions of this new accounting standard at the beginning of fiscal year 2018, and is currently assessing the impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. This topic converges the guidance within U.S. GAAP and IFRS. The new standard intends to simplify the presentation of debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, versus recording the costs as a prepaid expense in other assets that is amortized. The new standard will more closely align the presentation of debt issuance costs under U.S. GAAP with the presentation under comparable IFRS. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30) to address the measurement of debt issuance costs associated with line-of-credit arrangements. ASU 2015-15 states that an entity can defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless if there are outstanding borrowings on the line-of-credit arrangement. The Company adopted the provisions of this new accounting standard effective January 1, 2016 retrospectively. Accordingly, unamortized debt issuance costs of $7,964 were reclassified from other non-current assets to long-term debt in the December 31, 2015 consolidated balance sheet. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This update changes the measurement principle for inventory for entities using FIFO or average cost from the lower of cost or market to lower of cost and net realizable value. Entities that measure inventory using LIFO or the retail inventory method are not affected. This update will more closely align the accounting for inventory under U.S. GAAP with IFRS. The new guidance is effective for annual reporting periods beginning after December 15, 2016 including interim periods within that reporting period and early adoption is permitted. The Company currently accounts for inventory using the FIFO method. Accordingly, the Company plans to adopt the provisions of this update at the beginning of fiscal year 2017. This update is not expected to have a material impact on the Company's consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Under this ASU, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The Company adopted the provisions of this update effectively January 1, 2016 prospectively. This update did not have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases. The amendments in this Update create Topic 842, Leases, and supersede the requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. The guidance in this update is effective for annual reporting periods beginning after December 15, 2018 including interim periods within that reporting period and early adoption is permitted. The Company plans to adopt the provisions of this update at the beginning of fiscal year 2019, and is currently assessing the impact on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. This update simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance in this update is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods and early adoption is permitted. The Company plans to adopt the provisions of this update at the beginning of fiscal year 2017, and is currently assessing the impact 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. Topic 326 amends guidance on reporting credit losses by replacing the current incurred loss model with a forward-looking expected loss model. Current accounting delays the recognition of credit losses until it is probable a loss has been incurred. The update will require a financial asset measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net income. ASU 2016-13 is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted beginning after December 15, 2018. The Company plans to adopt the provisions of this update at the beginning of fiscal year 2020, and is currently assessing the impact on its consolidated financial statements.
