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 2017 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. 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 gains and losses on its foreign currency borrowings. The Company designated its €500,000 2.00% Senior Notes borrowing as a net investment hedge against a portion of its European operations. For the six months ended June 30, 2018 and July 1, 2017 , the change in the U.S. dollar value of the Company's euro denominated debt was a decrease of $15,984 ( $11,288 net of taxes) and an increase of $45,314 ( $28,321 net of taxes), respectively, which is recorded in the foreign currency translation adjustment component of other comprehensive income (loss). The increase 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 - Recently Adopted On January 1, 2018, the Company adopted the new accounting standard, ASC 606, Revenue from Contracts with Customers and all the related amendments (“ASC 606”) and applied the provisions of the standard to all contracts using the modified retrospective method. The cumulative effect of adopting the new revenue standard was immaterial and no adjustment has been recorded to the opening balance of retained earnings. Prior year information has not been restated and continues to be reported under the accounting standards in effect for those periods. Substantially all of the Company’s revenue continues to be recognized at a point in time when the product is either shipped or received from the Company's facilities and control of the product is transferred to the customer. The Company reviewed all of its revenue product categories under ASC 606 and the only changes identified were that an immaterial amount of revenue from intellectual property ("IP") contracts results in earlier recognition of revenue, new controls and processes designed to meet the requirements of the standard were implemented, and the required new disclosures are presented in Note 3, Revenue from Contracts with Customers. The adoption of ASC 606 did not have a material impact on the amounts reported in the Company's consolidated financial position, results of operations or cash flows. On January 1, 2018, the Company adopted the new accounting standard, ASU 2016-15, Statement of Cash Flows (Topic 230). The effect of adopting the new standard was not material. On January 1, 2018, the Company adopted the new accounting standard, ASU 2017-01, Business Combinations (Topic 805): Clarifying the definition of a business. The effect of adopting the new standard was not material. Recent Accounting Pronouncements - Effective in Future Years 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. Based on a preliminary assessment, the Company expects the adoption of this guidance to have a material impact on its assets and liabilities due to the recognition of right-of-use assets and lease liabilities on its consolidated balance sheets at the beginning of the earliest period presented. The Company is continuing its assessment, including identification of new controls and processes designed to meet the requirements of the topic and required new disclosures upon adoption, and may identify additional impacts this guidance will have on its consolidated financial statements and disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and other (Topic 350): Simplifying the test for goodwill impairment. The amendments remove the second step of the current goodwill impairment test. An entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. This guidance is effective for impairment tests in fiscal years beginning after December 15, 2019.

Business Combinations [Abstract]
Acquisitions	Acquisitions 2018 Acquisitions On November 20, 2017, the Company announced that it agreed to acquire Godfrey Hirst Group, the leading flooring company in Australia and New Zealand, further extending Mohawk's global position. The acquisition closed on July 2, 2018 , for A$556,000 ( $411,882 equivalent at June 30, 2018 ) and the Company is currently determining its preliminary purchase price allocation for acquired tangible and identifiable intangible assets, liabilities assumed, any non-controlling interest acquired, and goodwill. The results of the Godfrey Hirst Group will be reflected in the Flooring ROW segment. During the first quarter of 2018, the Company completed the acquisition of three businesses in the Flooring ROW segment for $24,410 , resulting in a preliminary goodwill allocation of $12,548 and intangibles subject to amortization of $7 . 2017 Acquisitions On April 4, 2017, the Company completed its purchase of Emilceramica S.r.l (“Emil”), a ceramic company in Italy. The total value of the acquisition was $186,099 . The Emil acquisition will enhance the Company's cost position and strengthen its combined brand and distribution in Europe. The acquisition's results and purchase price allocation have been included in the consolidated financial statements since the date of the acquisition. The Company's acquisition of Emil resulted in a goodwill allocation of $59,491 , indefinite-lived tradename intangible asset of $16,196 and an intangible asset subject to amortization of $2,348 . The goodwill is not expected to be deductible for tax purposes. The factors contributing to the recognition of the amount of goodwill include product, sales and manufacturing synergies. The Emil results are reflected in the Global Ceramic segment and the results of Emil's operations are not material to the Company's consolidated results of operations. During the second quarter of 2017, the Company completed the acquisition of two businesses in the Global Ceramic segment for $37,250 , resulting in a goodwill allocation of $1,002 . The Company also completed the acquisition of a business in the Flooring NA segment for $26,623 . During the first quarter of 2017, the Company acquired certain assets of a distribution business in the Flooring ROW segment for $1,407 , resulting in intangible assets subject to amortization of $827 .

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Revenue recognition and accounts receivable The Company recognizes revenues when it satisfies performance obligations as evidenced by the transfer of control of the promised goods to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods. The nature of the promised goods are ceramic, stone, carpet, resilient, laminate, wood and other flooring products. Payment is typically received 90 days or less from the invoice date. The Company adjusts the amounts of revenue for expected cash discounts, sales allowances, returns, and claims, based upon historical experience. The Company adjusts accounts receivable for doubtful account allowances based upon historical bad debt, claims experience, periodic evaluation of specific customer accounts, and the aging of accounts receivable. 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. Contract liabilities The Company historically records contract liabilities when it receives payment prior to fulfilling a performance obligation. Contract liabilities related to revenues are recorded in accounts payable and accrued expenses on the accompanying condensed consolidating balance sheets. The Company had contract liabilities of $42,938 and $29,124 as of June 30, 2018 and January 1, 2018 , respectively. Performance obligations Substantially all of the Company’s revenue is recognized at a point-in-time when the product is either shipped or received from the Company's facilities and control of the product is transferred to the customer. Accordingly, in any period, the Company does not recognize a significant amount of revenue from performance obligations satisfied or partially satisfied in prior periods and the amount of such revenue recognized during the three and six months ended June 30, 2018 was immaterial. Costs to obtain a contract The Company historically incurs certain incremental costs to obtain revenue contracts. These costs relate to marketing display structures and are capitalized when the amortization period is greater than one year, with the amount recorded in other assets on the accompanying condensed consolidated balance sheets. Capitalized costs to obtain contracts were $50,400 and $43,259 as of June 30, 2018 and January 1, 2018 , respectively. Amortization expense recognized during the six months ended June 30, 2018 related to these capitalized costs was $35,869 . Practical expedients and policy elections The Company elected the following practical expedients and policy elections: • Incremental costs of obtaining a contract is recorded as an expense when incurred in selling, general and administrative expenses if the amortization period is less than one year. • Shipping and handling activities performed after control has been transferred is accounted for as a fulfillment cost in cost of sales.

Restructuring and Related Activities [Abstract]
Restructuring, acquisition and integration-related costs	Restructuring, acquisition and integration-related costs The Company incurs costs in connection with acquiring, integrating and restructuring acquisitions and in connection with its global cost-reduction/productivity initiatives. For example: • In connection with acquisition activity, the Company typically incurs costs associated with executing the transactions, integrating the acquired operations (which may include expenditures for consulting and the integration of systems and processes), and restructuring the combined company (which may include charges related to employees, assets and activities that will not continue in the combined company); and • In connection with the Company's cost-reduction/productivity initiatives, it typically incurs costs and charges associated with site closings and other facility rationalization actions and workforce reductions.

Share-based Compensation [Abstract]
Stock-based compensation	Stock-based compensation The Company recognizes compensation expense for all share-based payments granted based on the grant-date fair value estimated in accordance with the provisions of the FASB ASC 718-10. Compensation expense is recognized on a straight-line basis over the options’ or other awards’ estimated lives for fixed awards with ratable vesting provisions. The Company granted 4 restricted stock units ("RSUs") at a weighted average grant-date fair value of $204.35 per unit for the three months ended June 30, 2018. The Company granted 127 RSUs at a weighted average grant-date fair value of $237.94 per unit for the six months ended June 30, 2018 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the quarter ended June 30, 2018 , the Company recorded income tax expense of $118,809 on earnings before income taxes of $316,354 for an effective tax rate of 37.6% , as compared to an income tax expense of $82,682 on earnings before income taxes of $344,430 , for an effective tax rate of 24.0% for the quarter ended July 1, 2017 . For the six months ended June 30, 2018 , the Company recorded income tax expense of $166,441 on earnings before income taxes of $573,227 for an effective tax rate of 29.0% as compared to an income tax expense of $151,040 on earnings before income taxes of $613,844 , for an effective tax rate of 24.6% for the six months ended July 1, 2017 . The effective tax rates for the three and six months ended June 30, 2018 were unfavorably impacted by Notice 2018-26, issued by the Department of the Treasury on April 2, 2018, which provided additional guidance on determining the amount of gross income to be recognized by U.S. taxpayers under the deemed repatriation of previously deferred foreign earnings. The effective tax rates for the three and six months ended June 30, 2018 were favorably impacted by tax reforms in Belgium and the U.S., which reduced the statutory rates from 33.99% to 29.58%, and 35% to 21%, respectively. The effective tax rates for the three and six months ended July 1, 2017 were favorably impacted by discrete items that occurred in the quarter ended July 1, 2017 . On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provided guidance on accounting for the income tax effects of the TCJA. SAB 118 provides a measurement period that should not extend beyond one year from the enactment date of the TCJA for companies to complete the accounting under ASC 740, Income Taxes ("ASC 740"). In accordance with SAB 118, a company must (1) reflect the income tax effects of those aspects of TCJA for which the accounting under ASC 740 is complete, (2) record a provisional estimate for those aspects of TCJA for which the accounting is incomplete but a reasonable estimate can be made, and/or (3) continue to apply ASC 740 on the basis of the provisions of tax laws in effect immediately before the enactment of the TCJA if no reasonable estimate can be made. The Company has not completed its accounting for the income tax effects of the TCJA but this will be completed within the one-year time period permitted by SAB 118. As disclosed in its December 31, 2017 10-K, the Company was able to make reasonable estimates and recorded a provisional amount in 2017 for the reduction of the U.S. corporate tax rate from 35% to 21% effective January 1, 2018. This estimate may be affected in future periods by other analysis to the TCJA, including, but not limited to, calculations of deemed repatriation of deferred foreign income and the state tax effect, expenditures that qualify for immediate expensing, and amounts limited for payments to covered employees. The Company analyzed Notice 2018-26, and has recorded $54,674 of additional net tax expense resulting from an increase of $100,865 for estimated Deemed Repatriation Transition Tax ("Transition Tax"), and decreases of $27,485 and $18,706 for reversals of unrecognized tax liabilities and transaction tax liabilities, respectively, during the quarter ended June 30, 2018 . The Transition Tax is a tax on previously untaxed earnings and profits (“E&P”) of certain foreign subsidiaries. To determine the amount of the Transition Tax, the Company must determine, in addition to other factors, the amount of post-1986 E&P of the relevant foreign subsidiaries, as well as the amount of non-U.S. income tax paid on such earnings. The Company made a provisional estimate of the Transition Tax obligation in 2017 and updated the provisional amount in the second quarter of 2018 ; however, the Company is continuing to gather additional information to compute a more precise amount. As of June 30, 2018 and December 31, 2017 , the Company has a liability of $206,030 and $105,165 , respectively, related to Transition Tax and will elect to pay the transition tax liability over the 8-year deferral period, with 8% due in each of the first five years, 15% in the sixth year, 20% in the seventh year, and 25% in the eighth year. As of June 30, 2018 , $17,522 of the Transition Tax obligation is recorded in accounts payable and accrued expenses, with the remaining $188,508 recorded in other long-term liabilities within the accompanying condensed consolidating balance sheets. Because of the complexity of the new Global Intangible Low-Taxed Income (“GILTI”) rules, the Company is continuing to evaluate this provision of the TCJA and the application of ASC 740. Accordingly, the accounting is incomplete, and the Company is not yet able to make reasonable estimates of the effects; therefore, no provisional estimates were recorded. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). The Company’s selection of an accounting policy with respect to the new GILTI tax rules will depend on complex calculations that the Company is unable to reasonably estimate at this time. The Company will continue to evaluate the interpretations of the TCJA, the assumptions made within the calculations, and future guidance that may be issued to determine the impact, if any, on these provisional calculations, which may materially change the Company’s tax determinations.

Earnings Per Share [Abstract]
Earnings per share	Earnings per share Basic earnings per common share is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted earnings per common share assumes the exercise of outstanding stock options and the vesting of RSUs using the treasury stock method when the effects of such assumptions are dilutive. A reconciliation of net earnings available to common stockholders and weighted-average common shares outstanding for purposes of calculating basic and diluted earnings per share is as follows: Three Months Ended Six Months Ended June 30, July 1, June 30, July 1, Net earnings attributable to Mohawk Industries, Inc. $ 196,586 260,681 405,352 461,235 Accretion of redeemable noncontrolling interest (a) — — (305 ) — Net earnings available to common stockholders $ 196,586 260,681 405,047 461,235 Weighted-average common shares outstanding-basic and diluted: Weighted-average common shares outstanding—basic 74,597 74,327 74,525 74,269 Add weighted-average dilutive potential common shares—options to purchase common shares and RSUs, net 340 474 403 504 Weighted-average common shares outstanding-diluted 74,937 74,801 74,928 74,773 Earnings per share attributable to Mohawk Industries, Inc.

Segment Reporting [Abstract]
Segment reporting	Segment reporting The Company has three reporting segments: the Global Ceramic segment, the Flooring NA segment and the Flooring ROW segment. The Global Ceramic segment designs, manufactures, sources and markets a broad line of ceramic tile, porcelain tile, natural stone tile and other products including natural stone, quartz and porcelain slab countertops, which it distributes primarily in North America, Europe and Russia through its network of regional distribution centers and Company-operated service centers.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies The Company is involved in litigation from time to time in the regular course of its business. Except as noted below, there are no material legal proceedings pending or known by the Company to be contemplated to which the Company is a party or to which any of its property is subject. Alabama Municipal Litigation In September 2016, the Water Works and Sewer Board of the City of Gadsden, Alabama (the “Gadsden Water Board”) filed an individual complaint in the Circuit Court of Etowah County, Alabama against certain manufacturers, suppliers, and users of chemicals containing perfluorinated compounds, including the Company. On October 26, 2016, the defendants removed the case to the United States District Court for the Northern District of Alabama, Middle Division, alleging diversity of citizenship and fraudulent joinder. The Gadsden Water Board filed a motion to remand the case back to the state court, and the defendants opposed the Gadsden Water Board’s motion. The federal court granted Gadsden Water Board's motion for remand. On October 24, 2017, the Company appealed the federal court's determination that co-defendant Industrial Chemicals, Inc. ("ICI") was properly joined as a party to the case. On February 22, 2018, the Court of Appeals dismissed the appeal for lack of jurisdiction. ICI's presence in the case deprives the federal court of jurisdiction over the case. In May, 2017, the Water Works and Sewer Board of the Town of Centre, Alabama (the “Centre Water Board”) filed a very similar complaint to the Gadsden Water Board complaint in the Circuit Court of Cherokee County. On June 19, 2017, the defendants removed this case to the United States District Court for the Northern District of Alabama, Middle Division, again alleging diversity of citizenship and fraudulent joinder. The Centre Water Board filed a motion to remand the case back to state court, and the defendants opposed the Centre Water Board’s motion. The federal court granted Centre Water Board's motion for remand. On December 6, 2017, the Company appealed the federal court's determination that co-defendant ICI was properly joined as a party to that case as well. On January 31, 2018, the Court of Appeals dismissed the appeal for lack of jurisdiction. ICI's presence in the case deprives the federal court of jurisdiction over the case. The Company filed a motion to dismiss in the Centre Water Board case on November 30, 2017 and a motion for judgment on the pleadings in the Gadsden Water Board case on October 25, 2017. Both motions argued that the courts did not have personal jurisdiction over the Company and that the complaints failed to state a claim on which relief could be granted. The Centre Water Board court denied the motion on May 15, 2018. On June 19, 2018, the Company filed a petition to the Alabama Supreme Court, seeking a ruling that the trial court erred in denying the motion to dismiss on the personal jurisdiction argument. That petition remains pending. The motion for judgment on the pleadings in the Gadsden Water Board case also remains pending. The Company has never manufactured perfluorinated compounds but purchased them for use in the manufacture of its carpets prior to 2007. The Gadsden and Centre Water Boards are not alleging that chemical levels in the Company’s wastewater discharge exceeded legal limits. Instead, the Gadsden and Centre Water Boards are seeking lost profits based on allegations that their customers decreased water purchases, as well as reimbursement for the cost of a filter and punitive damages. Belgian Tax Matter In January 2012, the Company received a €23,789 assessment from the Belgian tax authority related to its year ended December 31, 2008, asserting that the Company had understated its Belgian taxable income for that year. The Company filed a formal protest in the first quarter of 2012 refuting the Belgian tax authority's position. The Belgian tax authority set aside the assessment in the third quarter of 2012 and refunded all related deposits, including interest income of €1,583 earned on such deposits. However, on October 23, 2012, the Belgian tax authority notified the Company of its intent to increase the Company's taxable income for the year ended December 31, 2008 under a revised theory. On December 28, 2012, the Belgian tax authority issued assessments for the years ended December 31, 2005 and December 31, 2009, in the amounts of €46,135 and €35,567 , respectively, including penalties, but excluding interest. The Company filed a formal protest during the first quarter of 2013 relating to the new assessments. In September 2013, the Belgian tax authority denied the Company's protests, and the Company has brought these two years before the Court of First Appeal in Bruges. In December 2013, the Belgian tax authority issued additional assessments related to the years ended December 31, 2006, 2007, and 2010, in the amounts of €38,817 , €39,635 , and €43,117 , respectively, including penalties, but excluding interest. The Company filed formal protests during the first quarter of 2014, refuting the Belgian tax authority's position for each of the years assessed. In the quarter ended June 28, 2014, the Company received a formal assessment for the year ended December 31, 2008, totaling €30,131 , against which the Company also submitted its formal protest. All 4 additional years have been brought before the Court of First Appeal in November 2014. In January of 2015, the Company met with the Court of First Appeal in Bruges, Belgium and agreed with the Belgium tax authorities to consolidate and argue the issues regarding the years 2005 and 2009, and apply the ruling to all of the open years (to the extent there are no additional facts/procedural arguments in the other years). In May 2017, the statute of limitation was extended to include 2011. On January 27, 2016, the Court of First Appeal in Bruges, Belgium ruled in favor of the Company with respect to the calendar years ending December 31, 2005 and December 31, 2009. On March 9, 2016, the Belgian tax authority lodged its Notification of Appeal with the Ghent Court of Appeal. On June 13, 2018, the Court of First Appeal in Bruges, Belgium again ruled in favor of the Company with respect to the calendar years ending December 31, 2006, December 31, 2007, December 31, 2008, and December 31, 2010. The Company has now received positive rulings from the Court of First Appeal in Bruges on all calendar years 2005 through 2010, inclusive. The Company continues to disagree with the views of the Belgian tax authority on this matter and will persist in its vigorous defense. Nevertheless, on May 24, 2016, the tax collector representing the Belgian tax authorities imposed a lien on the Company's properties in Wielsbeke (Ooigemstraat and Breestraat), Oostrozebeke (Ingelmunstersteenweg) and Desselgem (Waregemstraat) included in the Flooring ROW segment. The purpose of the lien is to provide security for payment should the Belgian tax authority prevail on its appeal. The lien does not interfere with the Company's operations at these properties. General The Company believes that adequate provisions for resolution of all contingencies, claims and pending litigation have been made for probable losses that are reasonably estimable. These contingencies are subject to significant uncertainties and the Company is unable to estimate the amount or range of loss, if any, in excess of amounts accrued. The Company does not believe that the ultimate outcome of these actions will have a material adverse effect on its financial condition but could have a material adverse effect on its results of operations, cash flows or liquidity in a given quarter or year.

The 2015 Senior Credit Facility eliminated certain provisions in the 2013 Senior Credit Facility, including those that: (a) accelerated the maturity date to 90 days prior to the maturity of senior notes due in January 2016 if certain specified liquidity levels were not met; and (b) required that certain subsidiaries guarantee the Company's obligations if the Company’s credit ratings fell below investment grade. The 2015 Senior Credit Facility also modified certain negative covenants to provide the Company with additional flexibility, including flexibility to make acquisitions and incur additional indebtedness. On March 1, 2016, the Company amended the 2015 Senior Credit Facility to, among other things, carve out from the general limitation on subsidiary indebtedness the issuance of Euro-denominated commercial paper notes by subsidiaries. Additionally, at several points in 2016, the Company extended the maturity date of the 2015 Senior Credit Facility from March 26, 2020 to March 26, 2021. In the first half of 2017, the Company amended the 2015 Senior Credit Facility to extend the maturity date from March 26, 2021 to March 26, 2022. At the Company's election, revolving loans under the 2015 Senior Credit Facility bear interest at annual rates equal to either (a) LIBOR for 1, 2, 3 or 6 month periods, as selected by the Company, plus an applicable margin ranging between 1.00% and 1.75% ( 1.125% as of June 30, 2018 ), or (b) the higher of the Wells Fargo Bank, National Association prime rate, the Federal Funds rate plus 0.5% , or a monthly LIBOR rate plus 1.0% , plus an applicable margin ranging between 0.00% and 0.75% ( 0.125% as of June 30, 2018 ). The Company also pays a commitment fee to the lenders under the 2015 Senior Credit Facility on the average amount by which the aggregate commitments of the lenders' exceed utilization of the 2015 Senior Credit Facility ranging from 0.10% to 0.225% per annum ( 0.125% as of June 30, 2018 ). The applicable margins and the commitment fee are determined based on whichever of the Company's Consolidated Net Leverage Ratio or its senior unsecured debt rating (or if not available, corporate family rating) results in the lower applicable margins and commitment fee (with applicable margins and the commitment fee increasing as that ratio increases or those ratings decline, as applicable). The obligations of the Company and its subsidiaries in respect of the 2015 Senior Credit Facility are unsecured. The 2015 Senior Credit Facility includes certain affirmative and negative covenants that impose restrictions on the Company's financial and business operations, including limitations on liens, subsidiary indebtedness, fundamental changes, asset dispositions, dividends and other similar restricted payments, transactions with affiliates, future negative pledges, and changes in the nature of the Company's business. The Company is also required to maintain a Consolidated Interest Coverage Ratio of at least 3.0 to 1.0 and a Consolidated Net Leverage Ratio of no more than 3.75 to 1.0, each as of the last day of any fiscal quarter. The limitations contain customary exceptions or, in certain cases, do not apply as long as the Company is in compliance with the financial ratio requirements and is not otherwise in default. The 2015 Senior Credit Facility also contains customary representations and warranties and events of default, subject to customary grace periods. The Company paid financing costs of $567 in connection with the extension of its 2015 Senior Credit Facility from March 26, 2021 to March 26, 2022. These costs were deferred and, along with unamortized costs of $6,873 are being amortized over the term of the 2015 Senior Credit Facility. As of June 30, 2018 , amounts utilized under the 2015 Senior Credit Facility included $59,233 of borrowings and $55,220 of standby letters of credit related to various insurance contracts and foreign vendor commitments. The outstanding borrowings of $1,069,208 under the Company's U.S. and European commercial paper programs as of June 30, 2018 reduce the availability of the 2015 Senior Credit Facility. Including commercial paper borrowings, the Company has utilized $1,183,661 under the 2015 Senior Credit Facility resulting in a total of $616,339 available as of June 30, 2018 . Commercial Paper On February 28, 2014 and July 31, 2015 , the Company established programs for the issuance of unsecured commercial paper in the United States and Eurozone capital markets, respectively. Commercial paper issued under the U.S. and European programs will have maturities ranging up to 397 days and 183 days, respectively. None of the commercial paper notes may be voluntarily prepaid or redeemed by the Company and all rank pari passu with all of the Company's other unsecured and unsubordinated indebtedness. To the extent that the Company issues European commercial paper notes through a subsidiary of the Company, the notes will be fully and unconditionally guaranteed by the Company. The Company uses its 2015 Senior Credit Facility as a liquidity backstop for its commercial paper programs. Accordingly, the total amount outstanding under all of the Company's commercial paper programs may not exceed $1,800,000 (less any amounts drawn on the 2015 Credit Facility) at any time. The proceeds from the issuance of commercial paper notes are available for general corporate purposes. As of June 30, 2018 , there was $508,460 outstanding under the U.S. program, and the euro equivalent of $560,748 was outstanding under the European program. The weighted-average interest rate and maturity period for the U.S. program were 2.36% and 26.18 days, respectively. The weighted average interest rate and maturity period for the European program were (0.20)% and 26.53 days, respectively. Senior Notes On May 18, 2018 , Mohawk Capital Finance S.A. (“Mohawk Finance”), an indirect wholly-owned finance subsidiary of the Company, completed the issuance and sale of €300,000 aggregate principal amount of its Floating Rate Notes due May 18, 2020 ("2020 Floating Rate Notes"). The 2020 Floating Rate Notes are senior unsecured obligations of Mohawk Finance and rank pari passu with all of Mohawk Finance’s other existing and future senior unsecured indebtedness.

These notes bear interest at a rate per annum, reset quarterly, equal to three-month EURIBOR plus 0.3% (but in no event shall the interest rate be less than zero).

As defined in the related agreements, the Company's senior notes contain covenants, representations and warranties and events of default, subject to exceptions, and restrictions on the Company’s financial and business operations, including limitations on liens, restrictions on entering into sale and leaseback transactions, fundamental changes, and a provision allowing the holder of the notes to require repayment upon a change of control triggering event. Accounts Receivable Securitization On December 19, 2012, the Company entered into a three -year on-balance sheet trade accounts receivable securitization agreement (the "Securitization Facility"). On September 11, 2014, the Company made certain modifications to its Securitization Facility, which modifications, among other things, increased the aggregate borrowings available under the facility from $300,000 to $500,000 and decreased the interest margins on certain borrowings. Amounts borrowed under the Securitization Facility bore interest at LIBOR plus an applicable margin of 0.70% per annum and the borrower paid a commitment fee at a per annum rate of 0.30% on the unused amount of each lender’s commitment. On December 10, 2015 , the Company extended the termination date to December 19, 2016, and on December 13, 2016, the Company extended the termination date to December 19, 2017. The Company paid financing costs of $250 in connection with the second extension. These costs were deferred and are being amortized over the remaining term of the Securitization Facility.

Accounting Policies [Abstract]
Interim Reporting	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 2017 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.
Hedges of Net Investments in Non-U.S. Operations	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 gains and losses on its foreign currency borrowings.
Recent Accounting Pronouncements	Recent Accounting Pronouncements - Recently Adopted On January 1, 2018, the Company adopted the new accounting standard, ASC 606, Revenue from Contracts with Customers and all the related amendments (“ASC 606”) and applied the provisions of the standard to all contracts using the modified retrospective method. The cumulative effect of adopting the new revenue standard was immaterial and no adjustment has been recorded to the opening balance of retained earnings. Prior year information has not been restated and continues to be reported under the accounting standards in effect for those periods. Substantially all of the Company’s revenue continues to be recognized at a point in time when the product is either shipped or received from the Company's facilities and control of the product is transferred to the customer. The Company reviewed all of its revenue product categories under ASC 606 and the only changes identified were that an immaterial amount of revenue from intellectual property ("IP") contracts results in earlier recognition of revenue, new controls and processes designed to meet the requirements of the standard were implemented, and the required new disclosures are presented in Note 3, Revenue from Contracts with Customers. The adoption of ASC 606 did not have a material impact on the amounts reported in the Company's consolidated financial position, results of operations or cash flows. On January 1, 2018, the Company adopted the new accounting standard, ASU 2016-15, Statement of Cash Flows (Topic 230). The effect of adopting the new standard was not material. On January 1, 2018, the Company adopted the new accounting standard, ASU 2017-01, Business Combinations (Topic 805): Clarifying the definition of a business. The effect of adopting the new standard was not material. Recent Accounting Pronouncements - Effective in Future Years 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. Based on a preliminary assessment, the Company expects the adoption of this guidance to have a material impact on its assets and liabilities due to the recognition of right-of-use assets and lease liabilities on its consolidated balance sheets at the beginning of the earliest period presented. The Company is continuing its assessment, including identification of new controls and processes designed to meet the requirements of the topic and required new disclosures upon adoption, and may identify additional impacts this guidance will have on its consolidated financial statements and disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and other (Topic 350): Simplifying the test for goodwill impairment. The amendments remove the second step of the current goodwill impairment test. An entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. This guidance is effective for impairment tests in fiscal years beginning after December 15, 2019.
