Interim Financial Statements	Jun. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Interim Financial Statements The accompanying unaudited condensed consolidated financial statements represent the consolidation of LKQ Corporation, a Delaware corporation, and its subsidiaries. LKQ Corporation is a holding company and all operations are conducted by subsidiaries. When the terms "LKQ," "the Company," "we," "us," or "our" are used in this document, those terms refer to LKQ Corporation and its consolidated subsidiaries. We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") applicable to interim financial statements. Accordingly, certain information related to our significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted. These unaudited condensed consolidated financial statements reflect, in the opinion of management, all material adjustments (which include only normally recurring adjustments) necessary to fairly state, in all material respects, our financial position, results of operations and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of the results that can be expected for any subsequent interim period or for a full year. These interim financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on March 1, 2019 ("2018 Form 10-K").

Business Combinations

During the six months ended June 30, 2019, we completed five acquisitions, including one wholesale business and one self service business in North America, and three wholesale businesses in Europe. These acquisitions were not material to our results of operations or financial position as of and for the three and six months ended June 30, 2019. Total acquisition date fair value of the consideration for our acquisitions for the six months ended June 30, 2019 was $48 million, composed of $17 million of cash paid (net of cash acquired), $5 million for the estimated value of contingent payments to former owners (with maximum payments totaling $7 million), $1 million of other purchase price obligations (non-interest bearing), $21 million of notes payable, and $4 million of pre-existing balances considered to be effectively settled as a result of the acquisitions. In addition, we assumed $8 million of existing debt as of the acquisition dates.

On May 30, 2018, we acquired Stahlgruber GmbH ("Stahlgruber"), a leading European wholesale distributor of aftermarket spare parts for passenger cars, tools, capital equipment and accessories with operations in Germany, Austria, Italy, Slovenia, and Croatia, with further sales to Switzerland. Total acquisition date fair value of the consideration for our Stahlgruber acquisition was €1.2 billion ($1.4 billion), composed of €1.0 billion ($1.1 billion) of cash paid (net of cash acquired), and €215 million ($251 million) of newly issued shares of LKQ common stock. We financed the acquisition with the proceeds from €1.0 billion ($1.2 billion) of senior notes, the direct issuance to Stahlgruber's owner of 8,055,569 newly issued shares of LKQ common stock, and borrowings under our existing revolving credit facility. We recorded $915 million ($908 million in 2018 and $7 million of adjustments in the six months ended June 30, 2019) of goodwill related to our acquisition of Stahlgruber.

On May 3, 2018, the European Commission cleared the acquisition of Stahlgruber for the entire European Union, except with respect to the wholesale automotive parts business in the Czech Republic. The acquisition of Stahlgruber’s Czech Republic wholesale business was referred to the Czech Republic competition authority for review. On May 10, 2019, the Czech Republic competition authority approved our acquisition of Stahlgruber’s Czech Republic wholesale business subject to the requirement that we divest certain of the acquired locations. We acquired Stahlgruber’s Czech Republic wholesale business on May 29, 2019 and decided to divest all of the acquired locations. We immediately classified the business as discontinued operations because the business was never integrated into our Europe segment; see Note 3, "Discontinued Operations" for further information. The Czech Republic wholesale business represents an immaterial portion of Stahlgruber's revenue and profitability. There was no additional consideration beyond the previously remitted amounts for the Stahlgruber transaction required to complete the acquisition of the Czech Republic wholesale business.

In addition to our acquisition of Stahlgruber, during the year ended December 31, 2018, we completed acquisitions of four wholesale businesses in North America and nine wholesale businesses in Europe. Total acquisition date fair value of the consideration for these acquisitions was $99 million, composed of $85 million of cash paid (net of cash and restricted cash acquired), $11 million of notes payable, and $3 million for the estimated value of contingent payments to former owners (with maximum potential payments totaling $5 million). During the year ended December 31, 2018, we recorded $68 million of goodwill related to these acquisitions.

Our acquisitions are accounted for under the purchase method of accounting and are included in our consolidated financial statements from the dates of acquisition. The purchase prices were allocated to the net assets acquired based upon estimated fair values at the dates of acquisition. The purchase price allocations for the acquisitions made during the six months ended June 30, 2019 and the last six months of the year ended December 31, 2018 are preliminary as we are in the process of determining the following: 1) valuation amounts for certain receivables, inventories and fixed assets acquired; 2) valuation amounts for certain intangible assets acquired; 3) the acquisition date fair value of certain liabilities assumed; and 4) the tax basis of the entities acquired. We have recorded preliminary estimates for certain of the items noted above and will record adjustments, if any, to the preliminary amounts upon finalization of the valuations.

During the second quarter of 2019, the measurement period adjustments recorded for acquisitions completed in prior periods were not material. The income statement effect of these measurement period adjustments that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition dates was immaterial.

The purchase price allocations for the acquisitions completed during the year ended December 31, 2018 are as follows (in thousands):

(1)	The amounts recorded during the year ended December 31, 2018 include a $5 million adjustment to increase other intangibles related to our acquisition of Warn Industries, Inc. in 2017 and $4 million of adjustments to reduce other purchase price obligations related to other 2017 acquisitions.


(2)	The amount recorded for our acquisition of Stahlgruber includes a $79 million liability for certain pension obligations.

(3)

The amounts recorded during the year ended December 31, 2018 are due to the gains on bargain purchases related to (i) an acquisition in Europe completed in the second quarter of 2017 as a result of changes in the acquisition date fair value of the consideration, and (ii) three acquisitions in Europe completed during 2018 as a result of changes to our estimates of the fair values of the net assets acquired.

The fair value of our intangible assets is based on a number of inputs, including projections of future cash flows, discount rates, assumed royalty rates and customer attrition rates, all of which are Level 3 inputs. We used the relief-from-royalty method to value trade names, trademarks, software and other technology assets, and we used the multi-period excess earnings method to value customer relationships. The relief-from-royalty method assumes that the intangible asset has value to the extent that its owner is relieved of the obligation to pay royalties for the benefits received from the intangible asset. The multi-period excess earnings method is based on the present value of the incremental after-tax cash flows attributable only to the customer relationship after deducting contributory asset charges. The fair value of our property, plant and equipment is determined using inputs such as market comparables and current replacement or reproduction costs of the asset, adjusted for physical, functional and economic factors; these adjustments to arrive at fair value use unobservable inputs in which little or no market data exists, and therefore, these inputs are considered to be Level 3 inputs. See Note 12, "Fair Value Measurements" for further information regarding the tiers in the fair value hierarchy.

The acquisition of Stahlgruber expanded LKQ's geographic presence in continental Europe and serves as an additional strategic hub for our European operations. In addition, the acquisition of Stahlgruber allows for continued improvement in procurement, logistics and infrastructure optimization. The primary objectives of our other acquisitions made during the six months ended June 30, 2019 and the year ended December 31, 2018 were to create economic value for our stockholders by enhancing our position as a leading source for alternative collision and mechanical repair products and to expand into other product lines and businesses that may benefit from our operating strengths.

When we identify potential acquisitions, we attempt to target companies with a leading market presence, an experienced management team and workforce that provides a fit with our existing operations, and strong cash flows. For certain of our acquisitions, we have identified cost savings and synergies as a result of integrating the company with our existing business that provide additional value to the combined entity. In many cases, acquiring companies with these characteristics will result in purchase prices that include a significant amount of goodwill.

The following pro forma summary presents the effect of the businesses acquired during the six months ended June 30, 2019 as though the businesses had been acquired as of January 1, 2018, and the businesses acquired during the year ended December 31, 2018 as though they had been acquired as of January 1, 2017. We have excluded the May 29, 2019 acquisition of the Czech Republic wholesale business as the business was never integrated into our Europe segment. The pro forma adjustments are based upon unaudited financial information of the acquired entities (in thousands, except per share data):

Unaudited pro forma supplemental information is based upon accounting estimates and judgments that we believe are reasonable. The unaudited pro forma supplemental information includes the effect of purchase accounting adjustments, such as the adjustment of inventory acquired to fair value, adjustments to depreciation on acquired property, plant and equipment, adjustments to rent expense for above or below market leases, adjustments to amortization on acquired intangible assets, adjustments to interest expense, and the related tax effects. The pro forma impact of our acquisitions also reflects the elimination of acquisition related expenses, net of tax. Refer to Note 6, "Restructuring and Acquisition Related Expenses," for further information regarding our acquisition related expenses. These pro forma results are not necessarily indicative of what would have occurred if the acquisitions had been in effect for the periods presented or of future results.

Discontinued Operations [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations As described in Note 2, "Business Combinations," we classified the acquired Stahlgruber Czech Republic wholesale business as discontinued operations. We intend to divest the business within the next year, and thus, the net assets are reflected on the Unaudited Condensed Consolidated Balance Sheet at the lower of fair value less cost to sell or carrying value. As of June 30, 2019, the assets held for sale, liabilities held for sale, and noncontrolling interest are recorded within Prepaid expenses and other current assets, Other current liabilities, and Noncontrolling interest, respectively, on the Unaudited Condensed Consolidated Balance Sheet. As of the acquisition date, we acquired $5 million of cash and assumed $6 million of existing debt. Fair value was based on the estimated selling price, with factors including projected market multiples and any reasonable offers. Due to the uncertainties in the estimation process, it is possible that actual results could differ from the estimates used in the Company's analysis. The inputs utilized in the fair value estimate are classified as Level 3 within the fair value hierarchy. The fair value of the net assets was measured on a non-recurring basis as of June 30, 2019.

(1)	As of June 30, 2019, $61 million of inventory was included in assets held for sale. Refer to the "Net Assets Held for Sale" section for further information.

Aftermarket and refurbished products and salvage and remanufactured products are primarily composed of finished goods. As of June 30, 2019, manufactured products inventory was composed of $18 million of raw materials, $3 million of work in process, and $6 million of finished goods. As of December 31, 2018, manufactured products inventory was composed of $17 million of raw materials, $2 million of work in process, and $4 million of finished goods.

Net Assets Held for Sale

During the first half of 2019, we committed to plans to sell certain businesses in our North America and Europe segments. As a result, these businesses were classified as net assets held for sale and were required to be adjusted to the lower of fair value less cost to sell or carrying value, resulting in total impairment charges of $33 million and $49 million during the three and six months ended June 30, 2019, respectively, which were recorded within Impairment of net assets held for sale in the Unaudited Condensed Consolidated Statement of Income.

Excluding the Stahlgruber Czech Republic wholesale business discussed in Note 3, "Discontinued Operations," as of June 30, 2019, there were $56 million of assets held for sale, including $5 million of goodwill that was reclassified as held for sale related to our Europe segment, and $17 million of liabilities held for sale, which are recorded within Prepaid expenses and other current assets and Other current liabilities, respectively, on the Unaudited Condensed Consolidated Balance Sheet. We expect these businesses to be disposed of during the next twelve months. The businesses do not meet the requirements to be considered discontinued operations. These businesses generated annualized revenue of approximately $165 million during the twelve-month period ended June 30, 2019.

We are required to record net assets of our held for sale businesses at the lower of fair value less cost to sell or carrying value. Fair values were based on projected discounted cash flows and/or estimated selling prices. Management's assumptions for our discounted cash flow analysis of the businesses were based on projecting revenues and profits, tax rates, capital expenditures, working capital requirements and discount rates. For businesses for which we utilized estimated selling prices to calculate the fair value, factors included projected market multiples and any reasonable offers. Due to the uncertainties in the estimation process, it is possible that actual results could differ from the estimates used in the Company's analysis. The inputs utilized in the fair value estimates are classified as Level 3 within the fair value hierarchy. The fair values of the net assets were measured on a non-recurring basis as of June 30, 2019.

Investments in Unconsolidated Subsidiaries

Our investment in unconsolidated subsidiaries was $133 million and $179 million as of June 30, 2019 and December 31, 2018, respectively. On December 1, 2016, we acquired a 26.5% equity interest in Mekonomen AB ("Mekonomen") for an aggregate purchase price of $181 million. In October 2018, we acquired an additional $48 million of equity in Mekonomen at a discounted share price as part of its rights issue, increasing our equity interest to 26.6%. We are accounting for our interest in Mekonomen using the equity method of accounting, as our investment gives us the ability to exercise significant influence, but not control, over the investee. As of June 30, 2019, our share of the book value of Mekonomen's net assets exceeded the book value of our investment in Mekonomen by $5 million; this difference is primarily related to Mekonomen's Accumulated Other Comprehensive Income balance as of our acquisition date in 2016. We are recording our equity in the net earnings of Mekonomen on a one quarter lag. We recorded equity in earnings of $3 million and an equity loss of $37 million during the three and six months ended June 30, 2019, respectively, and equity in earnings of $1 million and $2 million during the three and six months ended June 30, 2018, respectively, related to our investment in Mekonomen, including adjustments to convert the results to GAAP and to recognize the impact of our purchase accounting adjustments and the other-than-temporary impairment (three months ended March 31, 2019 only) described below. In May 2018, we received a cash dividend of $8 million (SEK 67 million) related to our investment in Mekonomen. Mekonomen announced in February 2019 that the Mekonomen Board of Directors has proposed no dividend payment in 2019. The Level 1 fair value of our equity investment in the publicly traded Mekonomen common stock at June 30, 2019 was $125 million (using the Mekonomen share price of SEK 77 as of June 30, 2019) compared to a carrying value of $110 million.

During the three months ended March 31, 2019, we recognized an other-than-temporary impairment of $40 million, which represented the difference in the carrying value and the fair value of our investment in Mekonomen. The fair value of our investment in Mekonomen was determined using the Mekonomen share price of SEK 65 as of March 31, 2019. The impairment charge is recorded in Equity in earnings (losses) of unconsolidated subsidiaries on our Unaudited Condensed Consolidated Statements of Income. Equity in losses and earnings from our investment in Mekonomen are reported in the Europe segment.

Warranty Reserve

Some of our salvage mechanical products are sold with a standard six month warranty against defects. Additionally, some of our remanufactured engines are sold with a standard three year warranty against defects. We also provide a limited lifetime warranty for certain of our aftermarket products. These assurance-type warranties are not considered a separate performance obligation, and thus no transaction price is allocated to them. We record the warranty costs in Cost of goods sold on our Unaudited Condensed Consolidated Statements of Income. Our warranty reserve is calculated using historical claim information to project future warranty claims activity and is recorded within Other accrued expenses and Other noncurrent liabilities on our Unaudited Condensed Consolidated Balance Sheets based on the expected timing of the related payments.

The changes in the warranty reserve are as follows (in thousands):



Balance as of December 31, 2018	$	23,262
Warranty expense	29,529
Warranty claims	(22,770		)
Balance as of June 30, 2019	$	30,021

Litigation and Related Contingencies

We have certain contingencies resulting from litigation, claims and other commitments and are subject to a variety of environmental and pollution control laws and regulations incident to the ordinary course of business. We currently expect that the resolution of such contingencies will not materially affect our financial position, results of operations or cash flows.

Treasury Stock

On October 25, 2018, our Board of Directors authorized a stock repurchase program under which we may purchase up to $500 million of our common stock from time to time through October 25, 2021. Repurchases under the program may be made in the open market or in privately negotiated transactions, with the amount and timing of repurchases depending on market conditions and corporate needs. The repurchase program does not obligate us to acquire any specific number of shares and may be suspended or discontinued at any time. Delaware law imposes restrictions on stock repurchases. During the six months ended June 30, 2019, we repurchased 7.0 million shares of common stock for an aggregate price of $191 million. During 2018, we repurchased 2.3 million shares of common stock for an aggregate price of $60 million. As of June 30, 2019, there is $249 million of remaining capacity under our repurchase program. Repurchased shares are accounted for as treasury stock using the cost method.

Recent Accounting Pronouncements

Adoption of New Lease Standard

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-02, "Leases" ("ASU 2016-02"), which represents the FASB Accounting Standard Codification Topic 842 ("ASC 842"), to increase transparency and comparability by recognizing lease assets and lease liabilities on the Unaudited Condensed Consolidated Balance Sheets and disclosing key information about leasing arrangements. The main difference between the prior standard and ASU 2016-02 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under the prior standard.

We adopted the standard in the first quarter of 2019 using the modified retrospective approach and took advantage of the transition package of practical expedients permitted within the new standard, which, among other things, allows us to carryforward the historical lease classification. For leases with a term of 12 months or less, we elected the short-term lease exemption, which allowed us to not recognize right-of-use assets or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future. Additionally, we adopted the practical expedient to combine lease and non-lease components.

As of January 1, 2019, we recorded both an operating lease asset and operating lease liability of $1.3 billion. The preexisting deferred rent liability balances from the historical straight-line treatment of operating leases was reclassified as a reduction of the lease asset upon adoption. The adoption of the standard did not materially affect our Unaudited Condensed Consolidated Statements of Income or Statements of Cash Flows as operating lease payments will still be an operating cash outflow and capital lease payments will still be a financing cash outflow. The new standard did not have a material impact on our liquidity. The standard will have no impact on our debt covenant compliance under our current agreements as the covenant calculations are based on the prior lease accounting rules.

Other Recently Adopted Accounting Pronouncements

During the first quarter of 2019, we adopted ASU No. 2017-12, "Targeted Improvements to Accounting for Hedging Activities" ("ASU 2017-12"), which amends the hedge accounting recognition and presentation requirements in ASC 815 ("Derivatives and Hedging"). ASU 2017-12 significantly alters the hedge accounting model by making it easier for an entity to achieve and maintain hedge accounting and provides for accounting that better reflects an entity's risk management activities. We adopted the provisions of ASU 2017-12 by applying a modified retrospective approach to existing hedging relationships as of the adoption date. The adoption of ASU 2017-12 did not have a material impact on our unaudited condensed consolidated financial statements.

Recently Issued Accounting Pronouncements

In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement" ("ASU 2018-13"), which removes, modifies, and adds certain disclosure requirements in ASC 820. ASU 2018-13 is effective for fiscal years and interim periods beginning after December 15, 2019; early adoption is permitted. We are in the process of evaluating the impact of this standard on our disclosures but do not currently believe that it will have a material impact.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"), and in November 2018 issued a subsequent

amendment, ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses" ("ASU 2018-19"). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. ASU 2018-19 will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that represent the contractual right to receive cash. ASU 2016-13 and ASU 2018-19 should be applied on either a prospective transition or modified-retrospective approach depending on the subtopic. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. Early adoption is permitted for annual periods beginning after December 15, 2018, and interim periods therein. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements.

Restructuring and Acquisition Related Expenses [Abstract]
Business Acquisition, Integration, Restructuring and Other Related Costs [Text Block]	Restructuring and Acquisition Related Expenses Acquisition Related Expenses Acquisition related expenses, which include external costs such as legal, accounting and advisory fees, were immaterial for the three and six months ended June 30, 2019. Acquisition related expenses for the three and six months ended June 30, 2018 were $14 million and $16 million, respectively, which included external costs primarily related to our May 2018 acquisition of Stahlgruber. Acquisition Integration Plans and Restructuring During the three and six months ended June 30, 2019, we incurred $3 million and $6 million of restructuring expenses, respectively, related to our acquisition integration efforts. These expenses included approximately $1 million and $3 million for the three and six months ended June 30, 2019, respectively, related to the integration of our acquisition of Andrew Page Limited ("Andrew Page"). During the three and six months ended June 30, 2018, we incurred $2 million and $4 million of restructuring expenses, respectively. Restructuring expenses incurred during the three and six months ended June 30, 2018 were primarily related to the integration of our acquisition of Andrew Page. This integration included the closure of duplicate facilities and termination of employees. We expect to incur additional expenses related to the integration of certain of our acquisitions into our existing operations. These integration activities are expected to include the closure of duplicate facilities, rationalization of personnel in connection with the consolidation of overlapping facilities with our existing business, and moving expenses. Future expenses to complete these integration plans are currently expected to be approximately $15 million. 2019 Restructuring Program In the second quarter, we began implementing a cost reduction initiative, covering all three of our reportable segments, designed to eliminate underperforming assets and cost ineffectiveness. We have incurred and expect to incur costs for employee severance and related employee termination benefits; lease exit costs, such as lease termination fees and accelerated amortization of operating lease assets; and other costs related to facility closures, such as moving expenses to relocate inventory and equipment. During the three months ended June 30, 2019, we incurred $5 million of restructuring expense primarily related to employee severance and related termination benefits. We currently expect to incur additional expenses of between $20 million and $25 million through the end of 2020 to complete the program.

(4)	Amounts reclassified to Other (income) expense, net in our Unaudited Condensed Consolidated Statements of Income. These gains and losses offset the impact of the remeasurement of the underlying contracts.

Net unrealized losses related to our pension plans were reclassified to Other (income) expense, net in our Unaudited Condensed Consolidated Statements of Income during each of the six months ended June 30, 2019 and 2018. Our policy is to reclassify the income tax effect from Accumulated other comprehensive income (loss) to the Provision for income taxes when the related gains and losses are released to the Unaudited Condensed Consolidated Statements of Income.

During the first quarter of 2018, we adopted ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"), which allowed a reclassification from Accumulated other comprehensive income (loss) to Retained earnings for stranded tax effects resulting from the reduction of the U.S. federal statutory income tax rate to 21% from 35% due to the enactment of the Tax Cuts and Jobs Act of 2017 (the "Tax Act"). As a result of the adoption of ASU 2018-02 in the first quarter of 2018, we recorded a $5 million reclassification to increase Accumulated other comprehensive income (loss) and decrease Retained earnings.

Revenue Recognition [Abstract]

Revenue From Contract With Customer

Revenue Recognition

The majority of our revenue is derived from the sale of vehicle parts. We recognize revenue when the products are shipped to, delivered to or picked up by customers, which is the point when title has transferred and risk of ownership has passed.

Sources of Revenue

We report our revenue in two categories: (i) parts and services and (ii) other. The following table sets forth our revenue by category, with our parts and services revenue further disaggregated by reportable segment (in thousands):



	Three Months Ended				Six Months Ended

Total revenue	$	3,248,173	$	3,030,751	$	6,348,476	$	5,751,515

Parts and Services

Our parts revenue is generated from the sale of vehicle products including replacement parts, components and systems used in the repair and maintenance of vehicles and specialty products and accessories to improve the performance, functionality and appearance of vehicles. Services revenue includes (i) additional services that are generally billed concurrently with the related product sales, such as the sale of service-type warranties, (ii) fees for admission to our self service yards, and (iii) diagnostic and repair services.

In North America, our vehicle replacement products include sheet metal collision parts such as doors, hoods, and fenders; bumper covers; head and tail lamps; automotive glass products such as windshields; mirrors and grilles; wheels; and large mechanical items such as engines and transmissions. In Europe, our products include a wide variety of small mechanical products such as brake pads, discs and sensors; clutches; electrical products such as spark plugs and batteries; steering and suspension products; filters; and oil and automotive fluids. In our Specialty operations, we serve six product segments: truck and off-road; speed and performance; RV; towing; wheels, tires and performance handling; and miscellaneous accessories.

Our service-type warranties typically have service periods ranging from 6 months to 36 months. Under FASB Accounting Standards Codification Topic 606 ("ASC 606"), proceeds from these service-type warranties are deferred at contract inception and amortized on a straight-line basis to revenue over the contract period. The changes in deferred service-type warranty revenue are as follows (in thousands):



Balance as of January 1, 2019	$	24,006
Additional warranty revenue deferred	21,241
Warranty revenue recognized	(19,171		)
Balance as of June 30, 2019	$	26,076

Other Revenue

Revenue from other sources includes scrap sales, bulk sales to mechanical manufacturers (including cores) and sales of aluminum ingots and sows from our furnace operations. We derive scrap metal from several sources, including vehicles that have been used in both our wholesale and self service recycling operations and from original equipment manufacturers ("OEMs") and other entities that contract with us for secure disposal of "crush only" vehicles. The sale of hulks in our wholesale and self service recycling operations represents one performance obligation, and revenue is recognized based on a price per weight when the customer (processor) collects the scrap. Some adjustments may occur when the customer weighs the scrap at their location, and revenue is adjusted accordingly.

Revenue by Geographic Area

See Note 16, "Segment and Geographic Information" for information related to our revenue by geographic region.

Variable Consideration

The amount of revenue ultimately received from the customer can vary due to variable consideration which includes returns, discounts, rebates, refunds, credits, price concessions, incentives, performance bonuses, or other similar items. Under ASC 606 we are required to select the “expected value method” or the “most likely amount” method in order to estimate variable consideration. We utilize both methods in practice depending on the type of variable consideration, with contemplation of any expected reversals in revenue. We recorded a refund liability and return asset for expected returns of $107 million and $57 million as of June 30, 2019, respectively and $105 million and $56 million as of December 31, 2018. The refund liability is presented separately on the balance sheet within current liabilities while the return asset is presented within prepaid expenses and other current assets. Other types of variable consideration consist primarily of discounts, volume rebates, and other customer sales incentives which are recorded in Receivables, net on the Unaudited Condensed Consolidated Balance Sheets. We recorded a reserve for our variable consideration of $86 million and $103 million as of June 30, 2019 and December 31, 2018, respectively. While other customer incentive programs exist, we characterize them as material rights in the context of our sales transactions. We consider these programs to be immaterial to our unaudited condensed consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Derivative Instruments and Hedging Activities

We are exposed to market risks, including the effect of changes in interest rates, foreign currency exchange rates and commodity prices. Under our current policies, we use derivatives to manage our exposure to variable interest rates on our senior secured debt and changing foreign exchange rates for certain foreign currency denominated transactions. We do not hold or issue derivatives for trading purposes.

Cash Flow Hedges

We hold interest rate swap agreements to hedge a portion of the variable interest rate risk on our variable rate borrowings under our Credit Agreement, with the objective of minimizing the impact of interest rate fluctuations and stabilizing cash flows. Under the terms of the interest rate swap agreements, we pay the fixed interest rate and receive payment

at a variable rate of interest based on LIBOR for the respective currency of each interest rate swap agreement’s notional amount. Changes in the fair value of the interest rate swap agreements are recorded in Accumulated Other Comprehensive Income (Loss) and are reclassified to interest expense when the underlying interest payment has an impact on earnings. Our interest rate swap contracts have maturity dates ranging from January to June 2021.

From time to time, we may hold foreign currency forward contracts related to certain foreign currency denominated intercompany transactions, with the objective of minimizing the impact of fluctuating exchange rates on these future cash flows. Under the terms of the foreign currency forward contracts, we will sell the foreign currency in exchange for U.S. dollars at a fixed rate on the maturity dates of the contracts. Changes in the fair value of the foreign currency forward contracts are recorded in Accumulated Other Comprehensive Income (Loss) and reclassified to other income, net when the underlying transaction has an impact on earnings.

In 2016, we entered into three cross currency swap agreements for a total notional amount of $422 million (€400 million). The notional amount steps down by €15 million annually through 2020 with the remainder maturing in January 2021. These cross currency swaps contain an interest rate swap component and a foreign currency forward contract component that, combined with related intercompany financing arrangements, effectively convert variable rate U.S. dollar-denominated borrowings into fixed rate euro-denominated borrowings. The swaps are intended to minimize the impact of fluctuating exchange rates and interest rates on the cash flows resulting from the related intercompany financing arrangements. The changes in the fair value of the derivative instruments are recorded in Accumulated Other Comprehensive Income (Loss) and are reclassified to interest expense, net of interest income when the underlying transactions have an impact on earnings.

In October 2018, we entered into two cross currency swap agreements for a total notional amount of $184 million (€160 million). Half of the notional amount matures in October 2019 with the remainder in October 2020. The purpose of, and accounting for, the swaps are similar to those described in the previous paragraph.

The activity related to our cash flow hedges is presented in operating activities in our Unaudited Condensed Consolidated Statements of Cash Flows.

The following tables summarize the notional amounts and fair values of our designated cash flow hedges as of June 30, 2019 and December 31, 2018 (in thousands):



	Notional Amount		Fair Value at June 30, 2019 (USD)
	June 30, 2019		Other Current Assets		Other Noncurrent Assets		Other Accrued Expenses		Other Noncurrent Liabilities
Interest rate swap agreements

Cross currency swap agreements

Total cash flow hedges			$	1,004	$	8,525	$	181	$	32,998



	Notional Amount		Fair Value at December 31, 2018 (USD)
	December 31, 2018		Other Current Assets		Other Noncurrent Assets		Other Accrued Expenses		Other Noncurrent Liabilities
Interest rate swap agreements
USD denominated	$	480,000	$	—	$	14,967	$	—	$	—
Cross currency swap agreements
USD/euro	$	574,315	211		7,669		127		40,870
Total cash flow hedges			$	211	$	22,636	$	127	$	40,870

While certain derivative instruments executed with the same counterparty are subject to master netting arrangements, we present our cash flow hedge derivative instruments on a gross basis in our Unaudited Condensed Consolidated Balance Sheets. The impact of netting the fair values of these contracts would result in a decrease to Other Noncurrent Assets and Other Noncurrent Liabilities on our Unaudited Condensed Consolidated Balance Sheets of $5 million and $14 million at June 30, 2019 and December 31, 2018, respectively.

The activity related to our cash flow hedges is included in Note 9, "Accumulated Other Comprehensive Income (Loss)." As of June 30, 2019, we estimate that $1 million of derivative gains (net of tax) included in Accumulated Other Comprehensive Income (Loss) will be reclassified into our Unaudited Condensed Consolidated Statements of Income within the next 12 months.

Other Derivative Instruments

We hold other short-term derivative instruments, including foreign currency forward contracts, to manage our exposure to variability related to inventory purchases and intercompany financing transactions denominated in a non-functional currency. We have elected not to apply hedge accounting for these transactions, and therefore the contracts are adjusted to fair value through our results of operations as of each balance sheet date, which could result in volatility in our earnings. The notional amount and fair value of these contracts at June 30, 2019 and December 31, 2018, along with the effect on our results of operations during the three and six months ended June 30, 2019 and 2018, were immaterial.

Senior Secured Credit Agreement

On November 20, 2018, LKQ Corporation, LKQ Delaware LLP, and certain other subsidiaries (collectively, the "Borrowers") entered into Amendment No. 3 to the Fourth Amended and Restated Credit Agreement ("Credit Agreement"), which amended the Fourth Amended and Restated Credit Agreement dated January 29, 2016 by modifying certain terms to (1) increase the total availability under the revolving credit facility's multicurrency component from $2.75 billion to $3.15 billion; (2) reduce the margin on borrowings by 25 basis points at the September 30, 2018 leverage ratio, and reduce the number of leverage pricing tiers; (3) extend the maturity date by one year to January 29, 2024; (4) reduce the unused facility fee depending on leverage category; (5) increase the capacity for incurring additional indebtedness under our receivables securitization facility; (6) increase the maximum borrowing limit of swingline loans and add the ability to borrow in British Pounds and Euros; and (7) make other immaterial or clarifying modifications and amendments to the terms of the Credit Agreement. Borrowings will continue to bear interest at variable rates.

Amounts under the revolving credit facility are due and payable upon maturity of the Credit Agreement on January 29, 2024. Term loan borrowings, which totaled $346 million as of June 30, 2019, are due and payable in quarterly installments equal to $2 million on the last day of each of the first four fiscal quarters ending on or after March 31, 2019 and approximately $4 million on the last day of each fiscal quarter thereafter, with the remaining balance due and payable on January 29, 2024.

The increase in the revolving credit facility's multicurrency component of $400 million was used in part to pay down $240 million of the term loan (to the new $350 million amount that was outstanding as of the date of the amendment); the remainder will be used for general corporate purposes.

We are required to prepay the term loan by amounts equal to proceeds from the sale or disposition of certain assets if the proceeds are not reinvested within twelve months. We also have the option to prepay outstanding amounts under the Credit Agreement without penalty.

The Credit Agreement contains customary representations and warranties and customary covenants that provide limitations and conditions on our ability to enter into certain transactions. The Credit Agreement also contains financial and affirmative covenants, including limitations on our net leverage ratio and a minimum interest coverage ratio.

Borrowings under the Credit Agreement bear interest at variable rates, which depend on the currency and duration of the borrowing elected, plus an applicable margin. The applicable margin is subject to change in increments of 0.25% depending on our net leverage ratio. Interest payments are due on the last day of the selected interest period or quarterly in arrears depending on the type of borrowing. Including the effect of the interest rate swap agreements described in Note 11, "Derivative

Instruments and Hedging Activities," the weighted average interest rates on borrowings outstanding under the Credit Agreement at June 30, 2019 and December 31, 2018 were 1.6% and 1.9%, respectively. We also pay a commitment fee based on the average daily unused amount of the revolving credit facilities. The commitment fee is subject to change in increments of 0.05% depending on our net leverage ratio. In addition, we pay a participation commission on outstanding letters of credit at an applicable rate based on our net leverage ratio, and a fronting fee of 0.125% to the issuing bank, which are due quarterly in arrears.

Of the total borrowings outstanding under the Credit Agreement, there were $13 million classified as current maturities at June 30, 2019 compared to $9 million at December 31, 2018. As of June 30, 2019, there were letters of credit outstanding in the aggregate amount of $69 million. The amounts available under the revolving credit facilities are reduced by the amounts outstanding under letters of credit, and thus availability under the revolving credit facilities at June 30, 2019 was $1.9 billion.

Related to the execution of Amendment No. 3 to the Fourth Amended and Restated Credit Agreement in November 2018, we incurred $4 million of fees, the majority of which were capitalized as an offset to Long-Term Obligations and are amortized over the term of the agreement.

U.S. Notes (2023)

In 2013, we issued $600 million aggregate principal amount of 4.75% senior notes due 2023 (the "U.S. Notes (2023)"). The U.S. Notes (2023) are governed by the Indenture dated as of May 9, 2013 (the "U.S. Notes (2023) Indenture") among LKQ Corporation, certain of our subsidiaries (the "Guarantors"), the trustee, paying agent, transfer agent and registrar. The U.S. Notes (2023) are registered under the Securities Act of 1933.

The U.S. Notes (2023) bear interest at a rate of 4.75% per year from the most recent payment date on which interest has been paid or provided for. Interest on the U.S. Notes (2023) is payable in arrears on May 15 and November 15 of each year. The U.S. Notes (2023) are fully and unconditionally guaranteed, jointly and severally, by the Guarantors.

The U.S. Notes (2023) and the related guarantees are, respectively, LKQ Corporation's and each Guarantor's senior unsecured obligations and are subordinated to all of the Guarantors' existing and future secured debt to the extent of the assets securing that secured debt. In addition, the U.S. Notes (2023) are effectively subordinated to all of the liabilities of our subsidiaries that are not guaranteeing the U.S. Notes (2023) to the extent of the assets of those subsidiaries.

Euro Notes (2024)

On April 14, 2016, LKQ Italia Bondco S.p.A. (“LKQ Italia”), an indirect, wholly-owned subsidiary of LKQ Corporation, completed an offering of €500 million aggregate principal amount of senior notes due April 1, 2024 (the “Euro Notes (2024)”) in a private placement conducted pursuant to Regulation S and Rule 144A under the Securities Act of 1933. The proceeds from the offering were used to repay a portion of the revolver borrowings under the Credit Agreement and to pay related fees and expenses. The Euro Notes (2024) are governed by the Indenture dated as of April 14, 2016 (the “Euro Notes (2024) Indenture”) among LKQ Italia, LKQ Corporation and certain of our subsidiaries (the “Euro Notes (2024) Subsidiaries”), the trustee, and the paying agent, transfer agent, and registrar.

The Euro Notes (2024) bear interest at a rate of 3.875% per year from the date of original issuance or from the most recent payment date on which interest has been paid or provided for. Interest on the Euro Notes (2024) is payable in arrears on April 1 and October 1 of each year. The Euro Notes (2024) are fully and unconditionally guaranteed by LKQ Corporation and the Euro Notes (2024) Subsidiaries (the "Euro Notes (2024) Guarantors").

The Euro Notes (2024) and the related guarantees are, respectively, LKQ Italia’s and each Euro Notes (2024) Guarantor’s senior unsecured obligations and are subordinated to all of LKQ Italia's and the Euro Notes (2024) Guarantors’ existing and future secured debt to the extent of the assets securing that secured debt. In addition, the Euro Notes (2024) are effectively subordinated to all of the liabilities of our subsidiaries that are not guaranteeing the Euro Notes (2024) to the extent of the assets of those subsidiaries. The Euro Notes (2024) have been listed on the ExtraMOT, Professional Segment of the Borsa Italia S.p.A. securities exchange and the Global Exchange Market of Euronext Dublin.

Euro Notes (2026/28)

On April 9, 2018, LKQ European Holdings B.V. ("LKQ Euro Holdings"), a wholly-owned subsidiary of LKQ Corporation, completed an offering of €1.0 billion aggregate principal amount of senior notes. The offering consisted of €750 million senior notes due 2026 (the "2026 notes") and €250 million senior notes due 2028 (the "2028 notes" and, together with the 2026 notes, the "Euro Notes (2026/28)") in a private placement conducted pursuant to Regulation S and Rule 144A under the Securities Act of 1933. The proceeds from the offering, together with borrowings under our senior secured credit facility, were or will be used to (i) finance a portion of the consideration paid for the Stahlgruber acquisition, (ii) for general corporate

purposes and (iii) to pay related fees and expenses, including the refinancing of net financial debt. The Euro Notes (2026/28) are governed by the Indenture dated as of April 9, 2018 (the “Euro Notes (2026/28) Indenture”) among LKQ Euro Holdings, LKQ Corporation and certain of our subsidiaries (the “Euro Notes (2026/28) Subsidiaries”), the trustee, paying agent, transfer agent, and registrar.

The 2026 notes and 2028 notes bear interest at a rate of 3.625% and 4.125%, respectively, per year from the date of original issuance or from the most recent payment date on which interest has been paid or provided for. Interest on the Euro Notes (2026/28) is payable in arrears on April 1 and October 1 of each year. The Euro Notes (2026/28) are fully and unconditionally guaranteed by LKQ Corporation and the Euro Notes (2026/28) Subsidiaries (the "Euro Notes (2026/28) Guarantors").

The Euro Notes (2026/28) and the related guarantees are, respectively, LKQ Euro Holdings' and each Euro Notes (2026/28) Guarantor’s senior unsecured obligations and will be subordinated to all of LKQ Euro Holdings' and the Euro Notes (2026/28) Guarantors’ existing and future secured debt to the extent of the assets securing that secured debt. In addition, the Euro Notes (2026/28) are effectively subordinated to all of the liabilities of our subsidiaries that are not guaranteeing the Euro Notes (2026/28) to the extent of the assets of those subsidiaries. The Euro Notes (2026/28) have been listed on the Global Exchange Market of Euronext Dublin.

Related to the execution of the Euro Notes (2026/28) in April 2018, we incurred $16 million of fees, which were capitalized as an offset to Long-Term Obligations and are amortized over the term of the Euro Notes (2026/28).

Receivables Securitization Facility

On December 20, 2018, we amended the terms of our receivables securitization facility with MUFG Bank, Ltd. ("MUFG") (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) to: (i) extend the term of the facility to November 8, 2021; (ii) increase the maximum amount available to $110 million; and (iii) make other clarifying and updating changes. Under the facility, LKQ sells an ownership interest in certain receivables, related collections and security interests to MUFG for the benefit of conduit investors and/or financial institutions for cash proceeds. Upon payment of the receivables by customers, rather than remitting to MUFG the amounts collected, LKQ retains such collections as proceeds for the sale of new receivables generated by certain of the ongoing operations of the Company.

The sale of the ownership interest in the receivables is accounted for as a secured borrowing in our Unaudited Condensed Consolidated Balance Sheets, under which the receivables included in the program collateralize the amounts invested by MUFG, the conduit investors and/or financial institutions (the "Purchasers"). The receivables are held by LKQ Receivables Finance Company, LLC ("LRFC"), a wholly owned bankruptcy-remote special purpose subsidiary of LKQ, and therefore, the receivables are available first to satisfy the creditors of LRFC, including the Purchasers. While there were no borrowings on our receivables securitization facility as of June 30, 2019, $129 million of net receivables were available as collateral for the investment under the receivables facility, compared to $132 million as of December 31, 2018.

Under the receivables facility, we pay variable interest rates plus a margin on the outstanding amounts invested by the Purchasers. The variable rates are based on (i) commercial paper rates, (ii) London Interbank Offered Rate ("LIBOR"), or (iii) base rates, and are payable monthly in arrears. The commercial paper rate is the applicable variable rate unless conduit investors are not available to invest in the receivables at commercial paper rates. In such case, financial institutions will invest at the LIBOR rate or at base rates. We also pay a commitment fee on the excess of the investment maximum over the average daily outstanding investment, payable monthly in arrears. As of June 30, 2019, the interest rate under the receivables facility was based on commercial paper rates and was 3.4%. The outstanding balance was $110 million as of December 31, 2018 and there was no outstanding balance as of June 30, 2019. At December 31, 2018, we classified the outstanding balance as long-term on the Unaudited Condensed Consolidated Balance Sheets because we have the ability and intent to refinance these borrowings on a long-term basis.

Fair Value Measurements

Financial Assets and Liabilities Measured at Fair Value

We use the market and income approaches to estimate the fair value of our financial assets and liabilities, and during the three and six months ended June 30, 2019, there were no significant changes in valuation techniques or inputs related to the financial assets or liabilities that we have historically recorded at fair value. The tiers in the fair value hierarchy include: Level 1, defined as observable inputs such as quoted market prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as significant unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The following tables present information about our financial assets and liabilities measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation inputs we utilized to determine such fair value as of June 30, 2019 and December 31, 2018 (in thousands):



	Balance as of June 30, 2019		Fair Value Measurements as of June 30, 2019
	Balance as of June 30, 2019		Level 1		Level 2		Level 3

	Balance as of December 31, 2018		Level 1		Level 2		Level 3
Assets:
Cash surrender value of life insurance	$	47,649	$	—	$	47,649	$	—
Interest rate swaps	14,967		—		14,967		—
Cross currency swap agreements	7,880		—		7,880		—
Total Assets	$	70,496	$	—	$	70,496	$	—
Liabilities:

Deferred compensation liabilities	48,984		—		48,984		—
Cross currency swap agreements	40,997		—		40,997		—
Total Liabilities	$	95,190	$	—	$	89,981	$	5,209

The cash surrender value of life insurance is included in Other noncurrent assets on our Unaudited Condensed Consolidated Balance Sheets. The current portion of deferred compensation is included in Accrued payroll-related liabilities and the current portion of contingent consideration liabilities is included in Other current liabilities on our Unaudited Condensed Consolidated Balance Sheets; the noncurrent portion of these amounts is included in Other noncurrent liabilities on our Unaudited Condensed Consolidated Balance Sheets based on the expected timing of the related payments. The balance sheet classification of the interest rate swaps and cross currency swap agreements is presented in Note 11, "Derivative Instruments and Hedging Activities."

Our Level 2 assets and liabilities are valued using inputs from third parties and market observable data. We obtain valuation data for the cash surrender value of life insurance and deferred compensation liabilities from third party sources, which determine the net asset values for our accounts using quoted market prices, investment allocations and reportable trades. We value our other derivative instruments using a third party valuation model that performs a discounted cash flow analysis based on the terms of the contracts and market observable inputs such as current and forward interest rates and current and forward foreign exchange rates.

Our contingent consideration liabilities are related to our business acquisitions. Under the terms of the contingent consideration agreements, payments may be made at specified future dates depending on the performance of the acquired business subsequent to the acquisition. The liabilities for these payments are classified as Level 3 liabilities because the related fair value measurement, which is determined using an income approach, includes significant inputs not observable in the market.

Financial Assets and Liabilities Not Measured at Fair Value

Our debt is reflected on the Unaudited Condensed Consolidated Balance Sheets at cost. Based on market conditions as of both June 30, 2019 and December 31, 2018, the fair value of our credit agreement borrowings reasonably approximated the carrying values of $1.6 billion and $1.7 billion, respectively. In addition, based on market conditions, the fair value of the outstanding borrowings under the receivables facility reasonably approximated the carrying value of $110 million at December 31, 2018; as of June 30, 2019, there were no outstanding borrowings under the receivables facility. As of June 30, 2019 and December 31, 2018, the fair values of the U.S. Notes (2023) were approximately $608 million and $574 million, respectively, compared to a carrying value of $600 million at each date. As of June 30, 2019 and December 31, 2018, the fair values of the Euro Notes (2024) were approximately $631 million and $586 million compared to carrying values of $569 million and $573 million, respectively. As of June 30, 2019, the fair value of the Euro Notes (2026/28) was $1.2 billion compared to a carrying value of $1.1 billion; as of December 31, 2018, the fair value of the Euro Notes (2026/28) approximated the carrying value of $1.1 billion.

The fair value measurements of the borrowings under our credit agreement and receivables facility are classified as Level 2 within the fair value hierarchy since they are determined based upon significant inputs observable in the market, including interest rates on recent financing transactions with similar terms and maturities. We estimated the fair value by calculating the upfront cash payment a market participant would require at June 30, 2019 to assume these obligations. The fair value of our U.S. Notes (2023) is classified as Level 1 within the fair value hierarchy since it is determined based upon observable market inputs including quoted market prices in an active market. The fair values of our Euro Notes (2024) and Euro Notes (2026/28) are determined based upon observable market inputs including quoted market prices in markets that are not active, and therefore are classified as Level 2 within the fair value hierarchy.

Share-based Payment Arrangement [Abstract]

Equity Incentive Plans

Stock-Based Compensation

In order to attract and retain employees, non-employee directors, consultants, and other persons associated with us, we grant equity-based awards under the LKQ Corporation 1998 Equity Incentive Plan (the “Equity Incentive Plan”). We have granted restricted stock units ("RSUs"), stock options, and restricted stock under the Equity Incentive Plan. We expect to issue new or treasury shares of common stock to cover past and future equity grants.

RSUs

The RSUs we have issued vest over periods of up to five years, subject to a continued service condition. Currently outstanding RSUs (other than PSUs, which are described below) contain either a time-based vesting condition or a combination of a performance-based vesting condition and a time-based vesting condition, in which case both conditions must be met before any RSUs vest. For most of the RSUs containing a performance-based vesting condition, the Company must report positive diluted earnings per share, subject to certain adjustments, during any fiscal year period within five years following the grant date; we have an immaterial amount of RSUs containing other performance-based vesting conditions. Each RSU converts into one share of LKQ common stock on the applicable vesting date. The grant date fair value of RSUs is based on the market price of LKQ stock on the grant date. Our 2019 annual grant of RSUs occurred on March 1, 2019; in previous years, the annual grant occurred in mid-January.

Starting with our 2019 grants, participants who are eligible for retirement (defined as a voluntary separation of service from the Company after the participant has attained at least 60 years of age and completed at least five years of service) will continue to vest in their awards; if retirement occurs during the first year of the vesting period (for RSUs subject to a time-based vesting condition) or the first year of the performance period (for RSUs with a performance-based vesting condition), the participant vests in a prorated amount of the RSU grant based on the portion of the year employed. For our RSU grants prior to 2019, participants forfeit their unvested shares upon retirement.

The fair value of RSUs that vested during the six months ended June 30, 2019 was $11 million; the fair value of RSUs vested is based on the market price of LKQ stock on the date vested.

The following table summarizes activity related to our RSUs under the Equity Incentive Plan for the six months ended June 30, 2019:



	Number Outstanding		Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands) ⁽¹⁾
Unvested as of January 1, 2019	1,475,682		$	34.94
Granted	981,906		$	27.86
Vested	(416,262	)	$	32.72
Forfeited / Canceled	(48,674	)	$	34.25
Unvested as of June 30, 2019	1,992,652		$	31.93
Expected to vest after June 30, 2019	1,813,605		$	31.97	2.9	$	48,260


(1)	The aggregate intrinsic value of expected to vest RSUs represents the total pretax intrinsic value (the fair value of the Company's stock on the last day of each period multiplied by the number of units) that would have been received by the holders had all RSUs vested. This amount changes based on the market price of the Company’s common stock.

In 2019, we granted performance-based three-year RSUs ("PSUs") to certain employees, including our executive officers, under our Equity Incentive Plan. As these awards are performance-based, the exact number of shares to be paid out may be up to twice the grant amount, depending on the Company's performance and the achievement of certain performance metrics (adjusted earnings per share, average organic parts and services revenue growth, and average return on invested capital) over the three year period ending December 31, 2021. In 2019, we also granted an immaterial amount of performance-based RSUs to employees that have different performance metrics than those described above.

The following table summarizes activity related to our PSUs under the Equity Incentive Plan for the six months ended June 30, 2019:



	Number Outstanding	Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands) ⁽¹⁾
Unvested as of January 1, 2019	—	$	—
Granted⁽²⁾	136,170	$	27.69
Unvested as of June 30, 2019	136,170	$	27.69
Expected to vest after June 30, 2019	136,170	$	27.69	2.8	$	3,623

(1)

The aggregate intrinsic value of expected to vest PSUs represents the total pretax intrinsic value (the fair value of the Company's stock on the last day of each period multiplied by the number of units at target) that would have been received by the holders had all PSUs vested. This amount changes based on the market price of the Company’s common stock and the achievement of the performance metrics relative to the established targets.


(2)	Represents the number of PSUs at target payout.

Stock Options

Stock options vest over periods of up to five years, subject to a continued service condition. Stock options expire either six years or ten years from the date they are granted. No options were granted during the six months ended June 30, 2019. No options vested during the six months ended June 30, 2019; all of our outstanding options are fully vested.

The following table summarizes activity related to our stock options under the Equity Incentive Plan for the six months ended June 30, 2019:



	Number Outstanding		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands) ⁽¹⁾
Balance as of January 1, 2019	1,051,494		$	10.15
Exercised	(236,241	)	$	7.92		$	4,324
Canceled	(7,037	)	$	16.45
Balance as of June 30, 2019	808,216		$	10.75	0.5	$	13,000
Exercisable as of June 30, 2019	808,216		$	10.75	0.5	$	13,000

(1)

The aggregate intrinsic value of outstanding and exercisable options represents the total pretax intrinsic value (the difference between the fair value of the Company's stock on the last day of each period and the exercise price, multiplied by the number of options where the fair value exceeds the exercise price) that would have been received by the option holders had all option holders exercised their options as of the last day of the period indicated. This amount changes based on the market price of the Company’s common stock.

Stock-Based Compensation Expense

Pre-tax stock-based compensation expense for RSUs and PSUs totaled $8 million and $14 million for the three and six months ended June 30, 2019, respectively, and $6 million and $12 million for the three and six months ended June 30, 2018, respectively. As of June 30, 2019, unrecognized compensation expense related to unvested RSUs and PSUs was $51 million. Stock-based compensation expense related to these awards will be different to the extent that forfeitures are realized and performance under the PSUs differs from target.

Leases (Notes)

Leases [Abstract]

Leases [Text Block]

Leases

We lease certain warehouses, distribution centers, retail stores, office space, land, vehicles and equipment.

We determine if an arrangement is a lease at inception. Operating lease right-of-use ("ROU") assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. As the implicit rate for most of our leases is not readily determinable, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. Upon adoption of the new lease standard, we utilized the incremental borrowing rate as of the date of adoption. We determine our incremental borrowing rate by analyzing yield curves with consideration of lease term, and country and company specific factors. The operating lease ROU asset also includes any lease prepayments and excludes lease incentives.

Many of our leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 40 years or more. Our lease terms assumed in our measurement of the ROU assets and lease liabilities may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Some of our lease agreements include rental payments adjusted periodically for inflation. Most of these adjustments are considered variable lease costs. Other variable lease costs consist of certain non-lease components that are disclosed as lease costs due to our election of the practical expedient to combine lease and non-lease components and include items such as variable payments for utilities, property taxes, common area maintenance, sales taxes, and insurance.

For leases with an initial term of 12 months or less, we have not recognized an operating lease ROU asset or operating lease liability on the Unaudited Condensed Consolidated Balance Sheets; we recognize lease expense for these leases on a straight-line basis over the lease terms.

We guarantee the residual values for the majority of our vehicles. The residual values decline over the lease terms to a defined percentage of original cost. In the event the lessor does not realize the residual value when a vehicle is sold, we would be responsible for a portion of the shortfall. Similarly, if the lessor realizes more than the residual value when a vehicle is sold, we would be paid the amount realized over the residual value. Had we terminated all of our operating leases subject to these guarantees at June 30, 2019, our portion of the guaranteed residual value would have totaled approximately $75 million. Other than the residual value guarantees associated with our vehicles discussed above, we do not have any other material residual value guarantees or restrictive covenants.

The amounts recorded in the unaudited condensed consolidated balance sheet as of June 30, 2019 related to our lease agreements are as follows (in thousands):

As of June 30, 2019, we have additional minimum operating lease payments for leases that have not yet commenced of $75 million. These operating leases will commence between July 1, 2019 and December 31, 2020 with lease terms of 3 to 20 years. Most of these leases have not commenced as the assets are in the process of being constructed. We have appropriately considered the build-to-suit and sale-leaseback guidance where appropriate on these leases. No significant build-to-suit or sale-leaseback transactions have been identified.

Other information related to leases was as follows:

Employee Benefit Plans [Abstract]

Employee Benefit Plans

We have funded and unfunded defined benefit plans covering certain employee groups in the U.S. and various European countries. Local statutory requirements govern many of our European plans. The defined benefit plans are mostly closed to new participants and, in some cases, existing participants no longer accrue benefits. As of June 30, 2019 and December 31, 2018, the aggregate funded status of the defined benefit plans was a liability of $115 million and $110 million, respectively, and is reported in Other noncurrent liabilities and Accrued payroll-related liabilities on our Unaudited Condensed Consolidated Balance Sheets.

On June 28, 2019, we approved an amendment to terminate our primary defined benefit plan in the U.S. (the "U.S. Plan") and freeze all related benefit accruals, effective June 30, 2019. The distribution of the U.S Plan assets pursuant to the termination will not be made until the plan termination satisfies all regulatory requirements, which is expected to be completed in 2020. U.S. Plan participants will receive their full accrued benefits from plan assets by electing either lump sum distributions or annuity contracts with a qualifying third-party annuity provider. The resulting settlement effect of the U.S. Plan termination will be determined based on prevailing market conditions, the lump sum offer participation rate of eligible participants, the actual lump sum distributions, and annuity purchase rates at the date of distribution. As a result, we are currently unable to reasonably estimate either the timing or the final amount of such settlement charges. Based on the valuation performed as of June 28, 2019, the U.S. Plan has an underfunded status of $3 million.

Net periodic benefit cost for our defined benefit plans included the following components for the three and six months ended June 30, 2019 and 2018 (in thousands):



	Three Months Ended						Six Months Ended

For the three and six months ended June 30, 2019 and 2018, the service cost component of net periodic benefit cost was classified in Selling, general and administrative expenses, while the other components of net periodic benefit cost were classified in Other (income) expense, net in our Unaudited Condensed Consolidated Statements of Income.

Income Taxes (Notes)	6 Months Ended
Income Taxes (Notes)	Jun. 30, 2019
Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes At the end of each interim period, we estimate our annual effective tax rate and apply that rate to our interim earnings. We also record the tax impact of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and the effects of changes in tax laws or rates, in the interim period in which they occur. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in state and foreign jurisdictions, permanent and temporary differences between book and taxable income, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as the tax environment changes. Our effective income tax rate for the six months ended June 30, 2019 was 27.1%, compared to 26.3% for the comparable prior year period. The increase was primarily attributable to the impact of a favorable discrete item of approximately $3 million for the six months ended June 30, 2018, for excess tax benefits from stock-based payments; there was an immaterial amount for the six months ended June 30, 2019. The year over year change for this discrete item increased the effective tax rate by 0.7% compared to the prior year period, while the remaining discrete items increased the effective tax rate by an immaterial amount compared to the prior year period.

Segment Reporting [Abstract]

Segment and Geographic Information

We have four operating segments: Wholesale – North America, Europe, Specialty and Self Service. Our Wholesale – North America and Self Service operating segments are aggregated into one reportable segment, North America, because they possess similar economic characteristics and have common products and services, customers, and methods of distribution. Our reportable segments are organized based on a combination of geographic areas served and type of product lines offered. The reportable segments are managed separately as each business serves different customers (i.e. geographic in the case of North America and Europe and product type in the case of Specialty) and is affected by different economic conditions. Therefore, we present three reportable segments: North America, Europe and Specialty.

The following tables present our financial performance by reportable segment for the periods indicated (in thousands):

The key measure of segment profit or loss reviewed by our chief operating decision maker, who is our Chief Executive Officer, is Segment EBITDA. Segment EBITDA includes revenue and expenses that are controllable by the segment. Corporate general and administrative expenses are allocated to the segments based on usage, with shared expenses apportioned based on the segment's percentage of consolidated revenue. We calculate Segment EBITDA as EBITDA excluding restructuring and acquisition related expenses, change in fair value of contingent consideration liabilities, other gains and losses related to acquisitions, equity method investments, or divestitures, equity in losses and earnings of unconsolidated subsidiaries, and impairment charges. EBITDA, which is the basis for Segment EBITDA, is calculated as net income, less net income (loss) attributable to continuing and discontinued noncontrolling interest, excluding discontinued operations and discontinued noncontrolling interest, depreciation, amortization, interest and income tax expense.

The table below provides a reconciliation of Net Income to Segment EBITDA (in thousands):

We report net receivables; inventories; net property, plant and equipment; net operating lease assets; and equity method investments by segment as that information is used by the chief operating decision maker in assessing segment performance. These assets provide a measure for the operating capital employed in each segment. Unallocated assets include cash and cash equivalents, prepaid and other current and noncurrent assets, goodwill and other intangibles.

Our largest countries of operation are the U.S., followed by the U.K. and Germany. Additional European operations are located in the Netherlands, Italy, Czech Republic, Belgium, Poland, Slovakia, Austria, and other European countries. Our operations in other countries include operations in Canada, engine remanufacturing and bumper refurbishing operations in Mexico, an aftermarket parts freight consolidation warehouse in Taiwan, and administrative support functions in India. Our net sales are attributed to geographic area based on the location of the selling operation.

Condensed Consolidating Financial Information

LKQ Corporation (the "Parent") issued, and the Guarantors have fully and unconditionally guaranteed, jointly and severally, the U.S. Notes (2023) due on May 15, 2023. A Guarantor's guarantee will be unconditionally and automatically released and discharged upon the occurrence of any of the following events: (i) a transfer (including as a result of consolidation or merger) by the Guarantor to any person that is not a Guarantor of all or substantially all assets and properties of such Guarantor, provided the Guarantor is also released from its obligations with respect to indebtedness under the Credit Agreement or other indebtedness of ours, which obligation gave rise to the guarantee of the U.S. Notes (2023); (ii) a transfer (including as a result of consolidation or merger) to any person that is not a Guarantor of the equity interests of a Guarantor or issuance by a Guarantor of its equity interests such that the Guarantor ceases to be a subsidiary, as defined in the U.S. Notes (2023) Indenture, provided the Guarantor is also released from its obligations with respect to indebtedness under the Credit Agreement or other indebtedness of ours, which obligation gave rise to the guarantee of the U.S. Notes (2023); (iii) the release of the Guarantor from its obligations with respect to indebtedness under the Credit Agreement or other indebtedness of ours, which obligation gave rise to the guarantee of the U.S. Notes (2023); and (iv) upon legal defeasance, covenant defeasance or satisfaction and discharge of the U.S. Notes (2023) Indenture, as defined in the U.S. Notes (2023) Indenture.

Presented below are the unaudited condensed consolidating financial statements of the Parent, the Guarantors, the non-guarantor subsidiaries (the "Non-Guarantors"), and the elimination entries necessary to present our financial statements on a consolidated basis as required by Rule 3-10 of Regulation S-X of the Securities Exchange Act of 1934 resulting from the guarantees of the U.S. Notes (2023). Investments in consolidated subsidiaries have been presented under the equity method of accounting. The principal elimination entries eliminate investments in subsidiaries, intercompany balances, and intercompany revenue and expenses. The unaudited condensed consolidating financial statements below have been prepared from our financial information on the same basis of accounting as the unaudited condensed consolidated financial statements, and may not necessarily be indicative of the financial position, results of operations or cash flows had the Parent, Guarantors and Non-Guarantors operated as independent entities.

Accounting Policies [Abstract]
Disclosure of Long Lived Assets Held-for-sale [Table Text Block]	Net Assets Held for Sale During the first half of 2019, we committed to plans to sell certain businesses in our North America and Europe segments. As a result, these businesses were classified as net assets held for sale and were required to be adjusted to the lower of fair value less cost to sell or carrying value, resulting in total impairment charges of $33 million and $49 million during the three and six months ended June 30, 2019, respectively, which were recorded within Impairment of net assets held for sale in the Unaudited Condensed Consolidated Statement of Income. Excluding the Stahlgruber Czech Republic wholesale business discussed in Note 3, "Discontinued Operations," as of June 30, 2019, there were $56 million of assets held for sale, including $5 million of goodwill that was reclassified as held for sale related to our Europe segment, and $17 million of liabilities held for sale, which are recorded within Prepaid expenses and other current assets and Other current liabilities, respectively, on the Unaudited Condensed Consolidated Balance Sheet. We expect these businesses to be disposed of during the next twelve months. The businesses do not meet the requirements to be considered discontinued operations. These businesses generated annualized revenue of approximately $165 million during the twelve-month period ended June 30, 2019. We are required to record net assets of our held for sale businesses at the lower of fair value less cost to sell or carrying value. Fair values were based on projected discounted cash flows and/or estimated selling prices. Management's assumptions for our discounted cash flow analysis of the businesses were based on projecting revenues and profits, tax rates, capital expenditures, working capital requirements and discount rates. For businesses for which we utilized estimated selling prices to calculate the fair value, factors included projected market multiples and any reasonable offers. Due to the uncertainties in the estimation process, it is possible that actual results could differ from the estimates used in the Company's analysis. The inputs utilized in the fair value estimates are classified as Level 3 within the fair value hierarchy. The fair values of the net assets were measured on a non-recurring basis as of June 30, 2019.

Investments in Unconsolidated Subsidiaries [Abstract]
Equity Method Investments [Policy Text Block]	Investments in Unconsolidated Subsidiaries Our investment in unconsolidated subsidiaries was $133 million and $179 million as of June 30, 2019 and December 31, 2018, respectively. On December 1, 2016, we acquired a 26.5% equity interest in Mekonomen AB ("Mekonomen") for an aggregate purchase price of $181 million. In October 2018, we acquired an additional $48 million of equity in Mekonomen at a discounted share price as part of its rights issue, increasing our equity interest to 26.6%. We are accounting for our interest in Mekonomen using the equity method of accounting, as our investment gives us the ability to exercise significant influence, but not control, over the investee. As of June 30, 2019, our share of the book value of Mekonomen's net assets exceeded the book value of our investment in Mekonomen by $5 million; this difference is primarily related to Mekonomen's Accumulated Other Comprehensive Income balance as of our acquisition date in 2016. We are recording our equity in the net earnings of Mekonomen on a one quarter lag. We recorded equity in earnings of $3 million and an equity loss of $37 million during the three and six months ended June 30, 2019, respectively, and equity in earnings of $1 million and $2 million during the three and six months ended June 30, 2018, respectively, related to our investment in Mekonomen, including adjustments to convert the results to GAAP and to recognize the impact of our purchase accounting adjustments and the other-than-temporary impairment (three months ended March 31, 2019 only) described below. In May 2018, we received a cash dividend of $8 million (SEK 67 million) related to our investment in Mekonomen. Mekonomen announced in February 2019 that the Mekonomen Board of Directors has proposed no dividend payment in 2019. The Level 1 fair value of our equity investment in the publicly traded Mekonomen common stock at June 30, 2019 was $125 million (using the Mekonomen share price of SEK 77 as of June 30, 2019) compared to a carrying value of $110 million. During the three months ended March 31, 2019, we recognized an other-than-temporary impairment of $40 million, which represented the difference in the carrying value and the fair value of our investment in Mekonomen. The fair value of our investment in Mekonomen was determined using the Mekonomen share price of SEK 65 as of March 31, 2019. The impairment charge is recorded in Equity in earnings (losses) of unconsolidated subsidiaries on our Unaudited Condensed Consolidated Statements of Income. Equity in losses and earnings from our investment in Mekonomen are reported in the Europe segment.

Warranty Reserve [Abstract]

Standard Product Warranty And Extended Product Warranty Policy Policy [Policy Text Block]

Warranty Reserve

Some of our salvage mechanical products are sold with a standard six month warranty against defects. Additionally, some of our remanufactured engines are sold with a standard three year warranty against defects. We also provide a limited lifetime warranty for certain of our aftermarket products. These assurance-type warranties are not considered a separate performance obligation, and thus no transaction price is allocated to them. We record the warranty costs in Cost of goods sold on our Unaudited Condensed Consolidated Statements of Income. Our warranty reserve is calculated using historical claim information to project future warranty claims activity and is recorded within Other accrued expenses and Other noncurrent liabilities on our Unaudited Condensed Consolidated Balance Sheets based on the expected timing of the related payments.

The changes in the warranty reserve are as follows (in thousands):



Balance as of December 31, 2018	$	23,262

Treasury Stock [Abstract]
Stockholders' Equity, Policy [Policy Text Block]	Treasury Stock On October 25, 2018, our Board of Directors authorized a stock repurchase program under which we may purchase up to $500 million of our common stock from time to time through October 25, 2021. Repurchases under the program may be made in the open market or in privately negotiated transactions, with the amount and timing of repurchases depending on market conditions and corporate needs. The repurchase program does not obligate us to acquire any specific number of shares and may be suspended or discontinued at any time. Delaware law imposes restrictions on stock repurchases. During the six months ended June 30, 2019, we repurchased 7.0 million shares of common stock for an aggregate price of $191 million. During 2018, we repurchased 2.3 million shares of common stock for an aggregate price of $60 million. As of June 30, 2019, there is $249 million of remaining capacity under our repurchase program. Repurchased shares are accounted for as treasury stock using the cost method.

Adoption of New Lease Standard [Abstract]
Cumulative Effect of Adoption of ASC 842 on Consolidated Financial Statements [Policy Text Block]	In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-02, "Leases" ("ASU 2016-02"), which represents the FASB Accounting Standard Codification Topic 842 ("ASC 842"), to increase transparency and comparability by recognizing lease assets and lease liabilities on the Unaudited Condensed Consolidated Balance Sheets and disclosing key information about leasing arrangements. The main difference between the prior standard and ASU 2016-02 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under the prior standard. We adopted the standard in the first quarter of 2019 using the modified retrospective approach and took advantage of the transition package of practical expedients permitted within the new standard, which, among other things, allows us to carryforward the historical lease classification. For leases with a term of 12 months or less, we elected the short-term lease exemption, which allowed us to not recognize right-of-use assets or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future. Additionally, we adopted the practical expedient to combine lease and non-lease components. As of January 1, 2019, we recorded both an operating lease asset and operating lease liability of $1.3 billion. The preexisting deferred rent liability balances from the historical straight-line treatment of operating leases was reclassified as a reduction of the lease asset upon adoption. The adoption of the standard did not materially affect our Unaudited Condensed Consolidated Statements of Income or Statements of Cash Flows as operating lease payments will still be an operating cash outflow and capital lease payments will still be a financing cash outflow. The new standard did not have a material impact on our liquidity. The standard will have no impact on our debt covenant compliance under our current agreements as the covenant calculations are based on the prior lease accounting rules.

Recent Accounting Pronouncements Policy [Policy Text Block]	Recent Accounting Pronouncements Adoption of New Lease Standard In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-02, "Leases" ("ASU 2016-02"), which represents the FASB Accounting Standard Codification Topic 842 ("ASC 842"), to increase transparency and comparability by recognizing lease assets and lease liabilities on the Unaudited Condensed Consolidated Balance Sheets and disclosing key information about leasing arrangements.

The new standard did not have a material impact on our liquidity. The standard will have no impact on our debt covenant compliance under our current agreements as the covenant calculations are based on the prior lease accounting rules. Other Recently Adopted Accounting Pronouncements During the first quarter of 2019, we adopted ASU No. 2017-12, "Targeted Improvements to Accounting for Hedging Activities" ("ASU 2017-12"), which amends the hedge accounting recognition and presentation requirements in ASC 815 ("Derivatives and Hedging"). ASU 2017-12 significantly alters the hedge accounting model by making it easier for an entity to achieve and maintain hedge accounting and provides for accounting that better reflects an entity's risk management activities. We adopted the provisions of ASU 2017-12 by applying a modified retrospective approach to existing hedging relationships as of the adoption date. The adoption of ASU 2017-12 did not have a material impact on our unaudited condensed consolidated financial statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement" ("ASU 2018-13"), which removes, modifies, and adds certain disclosure requirements in ASC 820. ASU 2018-13 is effective for fiscal years and interim periods beginning after December 15, 2019; early adoption is permitted. We are in the process of evaluating the impact of this standard on our disclosures but do not currently believe that it will have a material impact. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"), and in November 2018 issued a subsequent amendment, ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses" ("ASU 2018-19"). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. ASU 2018-19 will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that represent the contractual right to receive cash. ASU 2016-13 and ASU 2018-19 should be applied on either a prospective transition or modified-retrospective approach depending on the subtopic. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. Early adoption is permitted for annual periods beginning after December 15, 2018, and interim periods therein. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements.

Revenue Recognition [Abstract]

Revenue [Policy Text Block]

Revenue Recognition

The majority of our revenue is derived from the sale of vehicle parts. We recognize revenue when the products are shipped to, delivered to or picked up by customers, which is the point when title has transferred and risk of ownership has passed.

Sources of Revenue

We report our revenue in two categories: (i) parts and services and (ii) other. The following table sets forth our revenue by category, with our parts and services revenue further disaggregated by reportable segment (in thousands):



	Three Months Ended				Six Months Ended

Total revenue	$	3,248,173	$	3,030,751	$	6,348,476	$	5,751,515

Parts and Services

Our parts revenue is generated from the sale of vehicle products including replacement parts, components and systems used in the repair and maintenance of vehicles and specialty products and accessories to improve the performance, functionality and appearance of vehicles. Services revenue includes (i) additional services that are generally billed concurrently with the related product sales, such as the sale of service-type warranties, (ii) fees for admission to our self service yards, and (iii) diagnostic and repair services.

In North America, our vehicle replacement products include sheet metal collision parts such as doors, hoods, and fenders; bumper covers; head and tail lamps; automotive glass products such as windshields; mirrors and grilles; wheels; and large mechanical items such as engines and transmissions. In Europe, our products include a wide variety of small mechanical products such as brake pads, discs and sensors; clutches; electrical products such as spark plugs and batteries; steering and suspension products; filters; and oil and automotive fluids. In our Specialty operations, we serve six product segments: truck and off-road; speed and performance; RV; towing; wheels, tires and performance handling; and miscellaneous accessories.

Our service-type warranties typically have service periods ranging from 6 months to 36 months. Under FASB Accounting Standards Codification Topic 606 ("ASC 606"), proceeds from these service-type warranties are deferred at contract inception and amortized on a straight-line basis to revenue over the contract period. The changes in deferred service-type warranty revenue are as follows (in thousands):



Balance as of January 1, 2019	$	24,006
Additional warranty revenue deferred	21,241
Warranty revenue recognized	(19,171		)
Balance as of June 30, 2019	$	26,076

Other Revenue

Revenue from other sources includes scrap sales, bulk sales to mechanical manufacturers (including cores) and sales of aluminum ingots and sows from our furnace operations. We derive scrap metal from several sources, including vehicles that have been used in both our wholesale and self service recycling operations and from original equipment manufacturers ("OEMs") and other entities that contract with us for secure disposal of "crush only" vehicles. The sale of hulks in our wholesale and self service recycling operations represents one performance obligation, and revenue is recognized based on a price per weight when the customer (processor) collects the scrap. Some adjustments may occur when the customer weighs the scrap at their location, and revenue is adjusted accordingly.

Revenue by Geographic Area

See Note 16, "Segment and Geographic Information" for information related to our revenue by geographic region.

Variable Consideration

The amount of revenue ultimately received from the customer can vary due to variable consideration which includes returns, discounts, rebates, refunds, credits, price concessions, incentives, performance bonuses, or other similar items. Under ASC 606 we are required to select the “expected value method” or the “most likely amount” method in order to estimate variable consideration. We utilize both methods in practice depending on the type of variable consideration, with contemplation of any expected reversals in revenue. We recorded a refund liability and return asset for expected returns of $107 million and $57 million as of June 30, 2019, respectively and $105 million and $56 million as of December 31, 2018. The refund liability is presented separately on the balance sheet within current liabilities while the return asset is presented within prepaid expenses and other current assets. Other types of variable consideration consist primarily of discounts, volume rebates, and other customer sales incentives which are recorded in Receivables, net on the Unaudited Condensed Consolidated Balance Sheets. We recorded a reserve for our variable consideration of $86 million and $103 million as of June 30, 2019 and December 31, 2018, respectively. While other customer incentive programs exist, we characterize them as material rights in the context of our sales transactions. We consider these programs to be immaterial to our unaudited condensed consolidated financial statements.

Cumulative Effect of Adoption of ASC 842 on Consolidated Financial Statements [Policy Text Block]	In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-02, "Leases" ("ASU 2016-02"), which represents the FASB Accounting Standard Codification Topic 842 ("ASC 842"), to increase transparency and comparability by recognizing lease assets and lease liabilities on the Unaudited Condensed Consolidated Balance Sheets and disclosing key information about leasing arrangements. The main difference between the prior standard and ASU 2016-02 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under the prior standard. We adopted the standard in the first quarter of 2019 using the modified retrospective approach and took advantage of the transition package of practical expedients permitted within the new standard, which, among other things, allows us to carryforward the historical lease classification. For leases with a term of 12 months or less, we elected the short-term lease exemption, which allowed us to not recognize right-of-use assets or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future. Additionally, we adopted the practical expedient to combine lease and non-lease components. As of January 1, 2019, we recorded both an operating lease asset and operating lease liability of $1.3 billion. The preexisting deferred rent liability balances from the historical straight-line treatment of operating leases was reclassified as a reduction of the lease asset upon adoption. The adoption of the standard did not materially affect our Unaudited Condensed Consolidated Statements of Income or Statements of Cash Flows as operating lease payments will still be an operating cash outflow and capital lease payments will still be a financing cash outflow. The new standard did not have a material impact on our liquidity. The standard will have no impact on our debt covenant compliance under our current agreements as the covenant calculations are based on the prior lease accounting rules.
