Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Business
	The financial statements presented in this report 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 are the nation’s largest provider of alternative vehicle collision replacement products and a leading provider of alternative vehicle mechanical replacement products, with our sales, processing, and distribution facilities reaching most major markets in the United States and Canada. We are also a leading provider of alternative vehicle replacement and maintenance products in the United Kingdom and the Benelux region of continental Europe. In addition to our wholesale operations, we operate self service retail facilities across the U.S. that sell recycled automotive products from end-of-life-vehicles. We also have operations in the Netherlands, Belgium, Northern France, Sweden, Norway, Mexico and Central America. In total, we operate more than 750 facilities.
	As described in Note 8, "Business Combinations," on January 3, 2014, we completed our acquisition of Keystone Automotive Holdings, Inc. ("Keystone Specialty"), a distributor and marketer of specialty vehicle aftermarket equipment and accessories in North America. With our acquisition of Keystone Specialty, we present an additional reportable segment, Specialty. Our consolidated financial statements reflect the impact of Keystone Specialty from the date of acquisition through December 31, 2014.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of LKQ Corporation and its subsidiaries. All intercompany transactions and accounts have been eliminated.
	Use of Estimates
	In preparing our financial statements in conformity with accounting principles generally accepted in the United States, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	Revenue Recognition
	The majority of our revenue is derived from the sale of vehicle parts. Revenue is recognized when the products are shipped to, delivered to or picked up by customers and title has transferred, subject to an allowance for estimated returns, discounts and allowances that we estimate based upon historical information. We recorded a reserve for estimated returns, discounts and allowances of approximately $31.3 million and $26.6 million at December 31, 2014 and 2013, respectively. We present taxes assessed by governmental authorities collected from customers on a net basis. Therefore, the taxes are excluded from revenue on our Consolidated Statements of Income and are shown as a current liability on our Consolidated Balance Sheets until remitted. We recognize revenue from the sale of scrap, cores and other metals when title has transferred, which typically occurs upon delivery to the customer. Revenue also includes amounts billed to customers for shipping and handling. Distribution expenses in the accompanying Consolidated Statements of Income are the costs incurred to prepare and deliver products to customers.
	Receivables and Allowance for Doubtful Accounts
	In the normal course of business, we extend credit to customers after a review of each customer's credit history. We recorded a reserve for uncollectible accounts of approximately $19.4 million and $14.4 million at December 31, 2014 and 2013, respectively. The reserve is based upon the aging of the accounts receivable, our assessment of the collectability of specific customer accounts and historical experience. Receivables are written off once collection efforts have been exhausted. Recoveries of receivables previously written off are recorded when received.
	Concentrations of Credit Risk
	Financial instruments that potentially subject us to significant concentration of credit risk consist primarily of cash and equivalents and accounts receivable. We control our exposure to credit risk associated with these instruments by (i) placing our cash and equivalents with several major financial institutions; (ii) holding high-quality financial instruments; and (iii) maintaining strict policies over credit extension that include credit evaluations, credit limits and monitoring procedures. In addition, our overall credit risk with respect to accounts receivable is limited to some extent because our customer base is composed of a large number of geographically diverse customers.
	Inventory
	We classify our inventory into the following categories: aftermarket and refurbished products; and salvage and remanufactured products.
	An aftermarket product is a new vehicle product manufactured by a company other than the original equipment manufacturer. Cost is established based on the average price we pay for parts, and includes expenses incurred for freight and overhead costs. For items purchased from foreign companies, import fees and duties and transportation insurance are also included. Refurbished inventory cost is based on the average price we pay for cores, which are recycled automotive parts that are not suitable for sale as a replacement part without further processing. The cost of our refurbished inventory also includes expenses incurred for freight, labor and other overhead.
	A salvage product is a recycled vehicle part suitable for sale as a replacement part. Cost is established based upon the price we pay for a vehicle, including auction, storage and towing fees, as well as expenditures for buying and dismantling. Inventory carrying value is determined using the average cost to sales percentage at each of our facilities and applying that percentage to the facility's inventory at expected selling prices, the assessment of which incorporates the sales probability based on a part's days in stock and historical demand. The average cost to sales percentage is derived from each facility's historical profitability for salvage vehicles. Remanufactured inventory cost is based upon the price paid for cores, and also includes expenses incurred for freight, direct manufacturing costs and overhead.
	For all inventory, carrying value is recorded at the lower of cost or market and is reduced to reflect current anticipated demand. If actual demand differs from our estimates, additional reductions to inventory carrying value would be necessary in the period such determination is made.
	Inventory consists of the following (in thousands):
		December 31,
		2014			2013
	Aftermarket and refurbished products	$	1,022,549		$	706,600
	Salvage and remanufactured products	411,298			370,352
		$	1,433,847		$	1,076,952
	Our acquisitions completed during 2014 and adjustments to preliminary valuations of inventory for certain of our 2013 acquisitions contributed $253.7 million of the increase in our aftermarket and refurbished products inventory and $20.8 million of the increase in our salvage and remanufactured products inventory during 2014. See Note 8, "Business Combinations" for further information on our acquisitions.
	Property and Equipment
	Property and equipment are recorded at cost less accumulated depreciation. Expenditures for major additions and improvements that extend the useful life of the related asset are capitalized. As property and equipment are sold or retired, the applicable cost and accumulated depreciation are removed from the accounts and any resulting gain or loss thereon is recognized. Construction in progress consists primarily of building and land improvements at our existing facilities. Depreciation is calculated using the straight-line method over the estimated useful lives or, in the case of leasehold improvements, the term of the related lease and reasonably assured renewal periods, if shorter.
	Our estimated useful lives are as follows:
	Land improvements	10-20 years
	Buildings and improvements	20-40 years
	Furniture, fixtures and equipment	3-20 years
	Computer equipment and software	3-10 years
	Vehicles and trailers	3-10 years
	Property and equipment consists of the following (in thousands):
		December 31,
		2014			2013
	Land and improvements	$	112,582		$	101,018
	Buildings and improvements	173,366			143,535
	Furniture, fixtures and equipment	337,125			282,862
	Computer equipment and software	125,888			108,424
	Vehicles and trailers	87,944			64,381
	Leasehold improvements	129,309			108,625
		966,214			808,845
	Less—Accumulated depreciation	(374,291		)	(294,183		)
	Construction in progress	38,064			31,989
		$	629,987		$	546,651
	We record depreciation expense within Depreciation and Amortization on our Consolidated Statements of Income. Additionally, included in Cost of Goods Sold on the Consolidated Statements of Income is depreciation expense associated with our refurbishing, remanufacturing, and furnace operations and our distribution centers. Total depreciation expense for the years ended December 31, 2014, 2013 and 2012 was $90.9 million, $72.7 million, and $60.7 million, respectively.
	Intangible Assets
	Intangible assets consist primarily of goodwill (the cost of purchased businesses in excess of the fair value of the identifiable net assets acquired) and other specifically identifiable intangible assets, such as trade names, trademarks, customer relationships, software and other technology related assets, and covenants not to compete.
	Goodwill is tested for impairment at least annually, and we performed annual impairment tests during the fourth quarters of 2014, 2013 and 2012. The results of all of these tests indicated that goodwill was not impaired.
	The changes in the carrying amount of goodwill by reportable segment are as follows (in thousands):
		North America			Europe			Specialty		Total
	Balance as of January 1, 2012	$	1,136,630		$	339,433		$	—	$	1,476,063

As these adjustments did not have a material impact on our financial position or results of operations, we recorded these adjustments to goodwill and amortization expense in 2014 and 2013, respectively.
	The components of other intangibles are as follows (in thousands):
		December 31, 2014								December 31, 2013

During 2014, we recorded $35.5 million of trade names, $65.1 million of customer relationships, $26.7 million of software and technology related assets and $1.9 million of covenants not to compete resulting from our 2014 acquisitions and adjustments to certain preliminary intangible asset valuations from our 2013 acquisitions. The trade names, customer relationships, and software and technology related assets recorded in 2014 included $22.0 million, $30.5 million, and $25.5 million, respectively, related to our acquisition of Keystone Specialty as discussed in Note 8, "Business Combinations." Other intangible assets resulting from our acquisition of Keystone Specialty were not material. We also recognized trade names and customer relationships of $10.1 million and $17.6 million, respectively, related to our 2014 acquisition of a supplier of replacement parts, supplies and accessories for recreational vehicles in our Specialty segment and customer relationships of $12.0 million related to our 2014 acquisition of an automotive core business.
During 2013, we recorded $23.9 million of trade names, $14.1 million of customer relationships, $19.3 million of software and technology related assets and $0.3 million of covenants not to compete resulting from our 2013 acquisitions and adjustments to certain preliminary intangible asset valuations from our 2012 acquisitions. The trade names, customer relationships, and software and technology related assets recorded in 2013 included $23.5 million, $2.5 million, and $19.3 million, respectively, related to our acquisition of Sator Beheer B.V. ("Sator") as discussed in Note 8, "Business Combinations." We also recognized $11.4 million of customer relationships related to our acquisitions of five automotive paint distributors in 2013.
Trade names and trademarks are amortized over a useful life ranging from 10 to 30 years on a straight-line basis. Customer relationships are amortized over the expected period to be benefited (5 to 20 years) on an accelerated basis. Software and other technology related assets are amortized on a straight-line basis over the expected period to be benefited (five to six years). Covenants not to compete are amortized over the lives of the respective agreements, which range from one to five years, on a straight-line basis. The weighted average amortization period for our intangible assets acquired during 2014 is 14 years. Amortization expense for intangibles was $34.5 million, $13.8 million and $9.5 million during the years ended December 31, 2014, 2013 and 2012, respectively. Estimated amortization expense for each of the five years in the period ending December 31, 2019 is $33.1 million, $30.0 million, $27.6 million, $22.4 million and $17.8 million, respectively.
Impairment of Long-Lived Assets
Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. There were no material adjustments to the carrying value of long-lived assets during the years ended December 31, 2014, 2013 or 2012.
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 that is supported by certain of the suppliers of those products. We record the estimated warranty costs at the time of sale using historical warranty claim information to project future warranty claims activity. The changes in the warranty reserve are as follows (in thousands):
Balance as of January 1, 2013	$	10,574
Warranty expense	29,674
Warranty claims	(27,801		)
Balance as of December 31, 2013	$	12,447
Warranty expense	30,370
Warranty claims	(27,936		)
Balance as of December 31, 2014	$	14,881
Self-Insurance Reserves
We self-insure a portion of employee medical benefits under the terms of our employee health insurance program. We purchase certain stop-loss insurance to limit our liability exposure. We also self-insure a portion of our property and casualty risk, which includes automobile liability, general liability, directors and officers liability, workers' compensation, and property coverage, under deductible insurance programs. The insurance premium costs are expensed over the contract periods. A reserve for liabilities associated with these losses is established for claims filed and claims incurred but not yet reported based upon our estimate of ultimate cost, which is calculated using analyses of historical data. We monitor new claims and claim development as well as trends related to the claims incurred but not reported in order to assess the adequacy of our insurance reserves. Total self-insurance reserves were $76.0 million and $55.6 million, including $36.4 million and $25.8 million classified as Other Accrued Expenses, as of December 31, 2014 and 2013, respectively. The remaining balances of self-insurance reserves are classified as Other Noncurrent Liabilities, which reflects management's estimates of when claims will be paid. The reserves presented on the Consolidated Balance Sheets are net of claims deposits of $0.6 million and $0.5 million at December 31, 2014 and 2013, respectively. In addition to these claims deposits, we had outstanding letters of credit of $59.2 million and $43.0 million at December 31, 2014 and 2013, respectively, to guarantee self-insurance claims payments. While we do not expect the amounts ultimately paid to differ significantly from our estimates, our insurance reserves and corresponding expenses could be affected if future claims experience differs significantly from historical trends and assumptions.
Income Taxes
Current income taxes are provided on income reported for financial reporting purposes, adjusted for transactions that do not enter into the computation of income taxes payable in the same year. Deferred income taxes have been provided to show the effect of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefit or that future deductibility is uncertain.
We recognize the benefits of uncertain tax positions taken or expected to be taken in tax returns in the provision for income taxes only for those positions that are more likely than not to be realized. We follow a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. Our policy is to include interest and penalties associated with income tax obligations in income tax expense.
U.S. federal income taxes are not provided on our interest in undistributed earnings of foreign subsidiaries when it is management's intent that such earnings will remain invested in those subsidiaries or other foreign subsidiaries. Taxes will be provided on these earnings in the period in which a decision is made to repatriate the earnings.
Investment in Unconsolidated Subsidiary
As of December 31, 2014, the carrying value of our investments in unconsolidated subsidiaries was $8.1 million; of this amount, $6.4 million relates to our investment in ACM Parts Pty Ltd ("ACM Parts"). In August 2013, we entered into an agreement with Suncorp Group, a leading general insurance group in Australia and New Zealand, to develop ACM Parts, an alternative vehicle replacement parts business in those countries. We hold a 49% interest in the entity and are contributing our experience to help establish automotive parts recycling operations and to facilitate the procurement of aftermarket parts; Suncorp Group holds a 51% equity interest and is supplying salvage vehicles to the venture as well as assisting in establishing relationships with repair shops as customers. We are accounting for our interest in this subsidiary using the equity method of accounting, as our investment gives us the ability to exercise significant influence, but not control, over the investee. The total of our investment in ACM Parts and other unconsolidated subsidiaries is included within Other Assets on our Consolidated Balance Sheets. Our equity in the net earnings of the investees for the years ended December 31, 2014 and 2013 was not material.
Rental Expense
We recognize rental expense on a straight-line basis over the respective lease terms, including reasonably assured renewal periods, for all of our operating leases.
Foreign Currency Translation
For most of our foreign operations, the local currency is the functional currency. Assets and liabilities are translated into U.S. dollars at the period-ending exchange rate. Statements of Income amounts are translated to U.S. dollars using average exchange rates during the period. Translation gains and losses are reported as a component of Accumulated Other Comprehensive Income (Loss) in stockholders' equity.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). This update outlines a new comprehensive revenue recognition model which supersedes most current revenue recognition guidance, and requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities adopting the standard have the option of using either a full retrospective or modified retrospective approach in the application of this guidance. ASU 2014-09 will be effective for the Company during the first quarter of our fiscal year 2017. Early adoption is not permitted. We are still evaluating the impact that ASU 2014-09 will have on our consolidated financial statements and related disclosures.
In June 2014, the FASB issued Accounting Standards Update 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period" ("ASU 2014-12"). This update requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition, and requires the recognition of compensation cost in the period in which it becomes probable that the performance target will be achieved. ASU 2014-12 will be effective for the Company during the first quarter of our fiscal year 2016. Early adoption is permitted. The new standard can be applied either prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements as an adjustment to opening retained earnings. We do not anticipate the adoption of this update will have a material impact on our financial position, results of operations, cash flows, or disclosures.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Incentive Plans	Equity Incentive Plans
	In order to attract and retain employees, non-employee directors, consultants, and other persons associated with us, we may grant qualified and nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance shares and performance units under the LKQ Corporation 1998 Equity Incentive Plan (the “Equity Incentive Plan”). The total number of shares approved by our stockholders for issuance under the Equity Incentive Plan is 69.9 million shares, subject to antidilution and other adjustment provisions. We have granted RSUs, stock options, and restricted stock under the Equity Incentive Plan. Of the shares approved by our stockholders for issuance under the Equity Incentive Plan, 13.3 million shares remained available for issuance as of December 31, 2014. We expect to issue new shares of common stock to cover past and future equity grants.
	RSUs
	RSUs vest over periods of up to five years, subject to a continued service condition. Each RSU converts into one share of LKQ common stock on the applicable vesting date. RSUs may not be sold, pledged or otherwise transferred until they vest. The grant date fair value of RSUs is based on the market price of LKQ stock on the grant date.
	In January 2014, the Compensation Committee approved the grant of 175,800 RSUs to our executive officers that include both a performance-based vesting condition and a time-based vesting condition. The performance-based vesting condition is the report by the Company of positive diluted earnings per share, subject to certain adjustments, during any fiscal year period within five years following the grant date (the "Performance Condition"). The time-based vesting condition is the vesting of 16.67% of the number of RSUs subject to the grant each six months following the grant date over a total of three years (the "Time Condition"). The Performance Condition was satisfied when LKQ reported its 2014 earnings on February 26, 2015 and, as a result, the portion of the RSUs that had previously met the Time Condition vested on such date and the remaining RSUs will vest according to the remaining schedule of the Time Condition.
	In March 2013, the Compensation Committee approved the grant to our executive officers of 275,400 RSUs that include both the Performance Condition and the Time Condition. Also in March 2013, the Compensation Committee approved the grant to our executive officers of 671,400 RSUs that have both a performance-based vesting condition (positive diluted earnings per share for the year ending December 31, 2013) and a time-based vesting condition as a replacement for the cancellation of an equal number of then unvested RSUs that had only a time-based vesting condition. The performance-based condition for the March 2013 RSU grants to our executive officers was satisfied.
	The fair value of RSUs that vested during the years ended December 31, 2014, 2013 and 2012 was $27.7 million, $14.4 million and $7.8 million, respectively.
	In January 2015, our Board of Directors granted 687,101 RSUs to employees (including executive officers).
	Stock Options
	Stock options vest over periods of up to five years, subject to a continued service condition. Stock options expire either six or ten years from the date they are granted. During 2014, we granted 126,755 stock options to employees. The grant date fair value of these options was immaterial to the financial statements, and thus we have not provided the detailed disclosures otherwise prescribed by the accounting guidance on stock options.
	The total grant-date fair value of options that vested during the years ended December 31, 2014, 2013 and 2012 was $3.3 million, $5.1 million and $7.2 million, respectively. The total intrinsic value (market value of stock less option exercise price) of stock options exercised was $38.4 million, $46.9 million and $45.3 million during the years ended December 31, 2014, 2013 and 2012, respectively.
	Restricted Stock
	Restricted stock vests over a five year period, subject to a continued service condition. Shares of restricted stock may not be sold, pledged or otherwise transferred until they vest. During the year ended December 31, 2014, all remaining unvested restricted stock became fully vested.
	The fair value of restricted stock that vested during the years ended December 31, 2014, 2013 and 2012 was $0.5 million, $2.3 million and $1.6 million, respectively.

	The RSUs containing a performance-based vesting condition that were granted in replacement of canceled RSUs were accounted for as a modification of the original awards, and therefore are not reflected as grants or cancellations in the table above.
	The following table summarizes information about RSUs and options at December 31, 2014:
		Shares			Weighted		Intrinsic				Weighted
					Average		Value				Average
					Remaining		(in thousands)				Exercise
					Contractual						Price
					Life (Yrs)

	Stock options - outstanding	5,207,772			3.6		105,038				8.04
	Stock options - expected to vest	5,169,746			3.6		105,038				7.86
	Stock options - exercisable	4,843,084			3.5		100,341				7.4
	The aggregate intrinsic value represents the total pre-tax intrinsic value based on our closing stock price of $28.12 on December 31, 2014. This amount changes based upon the fair market value of our common stock. The aggregate intrinsic value of total outstanding RSUs was $60.5 million at December 31, 2014.
	For the RSUs that contain both a performance-based vesting condition and a time-based vesting condition, we recognize compensation expense under the accelerated attribution method, pursuant to which expense is recognized over the requisite service period for each separate vesting tranche of the award. For the RSUs that were canceled and replaced, the fair values of the RSUs immediately before and after the modification were the same. As a result, there was no charge recorded in 2013 and the expense for these RSUs was continued at the grant date fair value. During the years ended December 31, 2014 and December 31, 2013, we recognized $8.2 million and $8.3 million, respectively, of stock based compensation expense related to the RSUs containing a performance-based vesting condition. For all other awards, which are subject to only a time-based vesting condition, we recognize compensation expense on a straight-line basis over the requisite service period of the entire award.
	In all cases, compensation expense is adjusted to reflect estimated forfeitures. When estimating forfeitures, we consider voluntary and involuntary termination behavior as well as analysis of historical forfeitures.
	The components of pre-tax stock-based compensation expense are as follows (in thousands):
		Year Ended December 31,
		2014				2013				2012

	Senior Secured Credit Agreement
	On March 27, 2014, LKQ Corporation, LKQ Delaware LLP, and certain other subsidiaries (collectively, the "Borrowers") entered into a third amended and restated credit agreement (the "Credit Agreement"). The Credit Agreement retains many of the terms of the Company’s second amended and restated credit agreement dated May 3, 2013 while also modifying certain terms to (1) extend the maturity date by one year to May 3, 2019; (2) increase the total availability under the Credit Agreement from $1.8 billion to $2.3 billion (composed of $1.69 billion in the revolving credit facility's multicurrency component, $165 million in the revolving credit facility's U.S. dollar only component, and $450 million of term loans); (3) reduce both the applicable margin on outstanding borrowings under the Credit Agreement and the commitment fee percentage we pay on average daily unused amounts under the revolving credit facilities; and (4) make other immaterial or clarifying modifications and amendments to the terms of the Company's second amended and restated credit agreement. The Credit Agreement allows the Company to increase the amount of the revolving credit facility or obtain incremental term loans up to the greater of $400 million or the amount that may be borrowed while maintaining a senior secured leverage ratio of less than or equal to 2.50 to 1.00, subject to the agreement of the lenders. The proceeds of the Credit Agreement were used to repay outstanding revolver borrowings and to pay fees related to the amendment and restatement.
	Amounts under the revolving credit facilities are due and payable upon maturity of the Credit Agreement on May 3, 2019. Term loan borrowings are due and payable in quarterly installments equal to 1.25% of the original principal amount beginning on June 30, 2014 with the remaining balance due and payable on the maturity date of the Credit Agreement. 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 contains 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 5, "Derivative Instruments and Hedging Activities," the weighted average interest rates on borrowings outstanding under the Credit Agreement at December 31, 2014 and December 31, 2013 were 2.10% and 3.05%, 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, as well as 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, $22.5 million was classified as current maturities at both December 31, 2014 and December 31, 2013. As of December 31, 2014, there were letters of credit outstanding in the aggregate amount of $60.4 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 December 31, 2014 was $1.1 billion.
	Related to the execution of the Credit Agreement in March 2014, we incurred $3.7 million of fees, of which $3.4 million were capitalized within Other Assets on our Consolidated Balance Sheet and are amortized over the term of the agreement. The remaining $0.3 million of fees were expensed during the year ended December 31, 2014 as a loss on debt extinguishment. Related to the execution of the second amended and restated credit agreement in May 2013, we incurred $7.2 million of fees, of which $6.1 million were capitalized within Other Assets on our Consolidated Balance Sheet. The remaining $1.1 million of fees, together with $1.7 million of capitalized debt issuance costs related to the original credit agreement, were expensed during the year ended December 31, 2013 as a loss on debt extinguishment.
	Senior Notes
	On May 9, 2013, LKQ Corporation completed an offering of $600 million aggregate principal amount of senior notes due May 15, 2023 (the "Original Notes") in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of 1933. In April 2014, LKQ Corporation completed an offer to exchange $600 million aggregate principal amount of registered 4.75% Senior Notes due 2023 (the "Notes") for the Original Notes. The Notes are governed by the Indenture dated as of May 9, 2013 among LKQ Corporation, certain of our subsidiaries (the "Guarantors") and U.S. Bank National Association, as trustee. The Notes are substantially identical to the Original Notes, except the Notes are registered under the Securities Act of 1933, and the transfer restrictions, registration rights, and related additional interest provisions applicable to the Original Notes do not apply to the Notes.
	The Notes bear interest at a rate of 4.75% per year from the date of the original issuance or from the most recent payment date on which interest has been paid or provided for. Interest on the Notes is payable in arrears on May 15 and November 15 of each year. The first interest payment was made on November 15, 2013. The Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors.
	The Notes and the 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 Notes are effectively subordinated to all of the liabilities of our subsidiaries that are not guaranteeing the Notes to the extent of the assets of those subsidiaries.
	Fees incurred related to the offering of the Notes totaling $9.7 million were capitalized during the year ended December 31, 2013 within Other Assets on our Consolidated Balance Sheet and are amortized over the term of the Notes.
	Restricted Payments
	Our senior secured credit agreement and our senior notes indenture contain limitations on payment of cash dividends or other distributions of assets. Based on limitations in effect under our senior secured credit agreement and senior notes indenture as of December 31, 2014, the maximum amount of dividends we could pay in 2015 is approximately $550 million. The limit on the payment of dividends is calculated using historical financial information and will change from period to period.
	Receivables Securitization Facility
	On September 28, 2012, we entered into a three year receivables securitization facility with BTMU as Administrative Agent. Under the facility, LKQ sells an ownership interest in certain receivables, related collections and security interests to BTMU for the benefit of conduit investors and/or financial institutions for up to $80 million in cash proceeds. Upon payment of the receivables by customers, rather than remitting to BTMU 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. On September 29, 2014, the parties amended the terms of the facility to: (i) extend the term of the facility to October 2, 2017; (ii) increase the maximum amount available to $97 million; and (iii) make other clarifying and updating changes.
	The sale of the ownership interest in the receivables is accounted for as a secured borrowing in our Consolidated Balance Sheets, under which the receivables included in the program collateralize the amounts invested by BTMU, 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 investors. As of December 31, 2014, $129.5 million of net receivables were collateral for the investment under the receivables facility. There were no borrowings outstanding under the receivables facility as of December 31, 2013.
	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) the London InterBank Offered Rate ("LIBOR"), or (iii) base rates, and are payable monthly in arrears. Commercial paper rates will be 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 December 31, 2014, the interest rate under the receivables facility was based on commercial paper rates and was 0.93%. The outstanding balance of $94.9 million as of December 31, 2014 was classified as long-term on the Consolidated Balance Sheets because we have the ability and intent to refinance these borrowings on a long-term basis.

Derivative Instruments and Hedging Activities	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, changing foreign exchange rates for certain foreign currency denominated transactions and changes in metals prices. We do not hold or issue derivatives for trading purposes.
	Cash Flow Hedges
	At December 31, 2014, we had interest rate swap agreements in place 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 or the Canadian Dealer Offered Rate (“CDOR”) for the respective currency of each interest rate swap agreement’s notional amount. The effective portion of changes in the fair value of the interest rate swap agreements is recorded in Accumulated Other Comprehensive Income (Loss) and is reclassified to interest expense when the underlying interest payment has an impact on earnings. The ineffective portion of changes in the fair value of the interest rate swap agreements is reported in interest expense. Our interest rate swap contracts have maturity dates ranging from 2015 through 2016.
	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 changing exchange rates on these future cash flows, as well as minimizing the impact of fluctuating exchange rates on our results of operations through the respective dates of settlement. 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. The effective portion of the changes in fair value of the foreign currency forward contracts is recorded in Accumulated Other Comprehensive Income (Loss) and reclassified to other income (expense) when the underlying transaction has an impact on earnings. In the year ended December 31, 2014, we settled our £70 million and €150 million foreign currency forward contracts through payments to the counterparties totaling $20.0 million. At that time, we also settled the underlying intercompany debt transactions.
	The following table summarizes the notional amounts and fair values of our designated cash flow hedges as of December 31, 2014 and 2013 (in thousands):
		Notional Amount				Fair Value at December 31, 2014 (USD)				Fair Value at December 31, 2013 (USD)
		31-Dec-14		31-Dec-13		Other Accrued Expenses		Other Noncurrent Liabilities		Other Accrued Expenses		Other Noncurrent Liabilities

	Total cash flow hedges					$	2,691	$	2,527	$	21,818	$	8,470
	While our 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 Consolidated Balance Sheets. The impact of netting the fair values of these contracts would not have a material effect on our Consolidated Balance Sheets at December 31, 2014 or 2013.
	The activity related to our cash flow hedges is included in Note 12, "Accumulated Other Comprehensive Income (Loss)." In May 2013, we repaid a portion of our variable rate U.S. dollar denominated credit agreement borrowings with the proceeds of our fixed rate senior notes, which resulted in one of our interest rate swap contracts, which expired in October 2013, no longer being designated as an effective cash flow hedge. Ineffectiveness related to our cash flow hedges was immaterial to our results of operations during 2014, 2013, and 2012. We do not expect future ineffectiveness related to our cash flow hedges to have a material effect on our results of operations.
	As of December 31, 2014, we estimate that $3.1 million of derivative losses (net of tax) included in Accumulated Other Comprehensive Income will be reclassified into our 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, as well as commodity forward contracts to manage our exposure to fluctuations in metals prices. 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 December 31, 2014 and 2013, along with the effect on our results of operations in 2014, 2013 and 2012 were immaterial.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	Financial Assets and Liabilities Measured at Fair Value
	We use the market and income approaches to value our financial assets and liabilities, and during the year ended December 31, 2014, 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 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 December 31, 2014 and 2013 (in thousands):
		Balance as of December 31, 2014				Fair Value Measurements as of December 31, 2014
						Level 1		Level 2		Level 3

	Interest rate swaps	8,470				—		8,470		—
	Total Liabilities	$	111,173			$	—	$	55,520	$	55,653
	The cash surrender value of life insurance and deferred compensation liabilities are included in Other Assets and Other Noncurrent Liabilities, respectively, on our Consolidated Balance Sheets. The current portion of contingent consideration liabilities is classified as a separate line item in current liabilities and the noncurrent portion is included in Other Noncurrent Liabilities on our Consolidated Balance Sheets based on the expected timing of the related payments. The balance sheet classification of the interest rate swaps and foreign currency forward contracts is presented in Note 5, "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 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 as further described in Note 8, "Business Combinations." 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. These unobservable inputs include internally-developed assumptions of the probabilities of achieving specified targets, which are used to determine the resulting cash flows and the applicable discount rate. Our Level 3 fair value measurements are established and updated quarterly by our corporate accounting department using current information about these key assumptions, with the input and oversight of our operational and executive management teams. We evaluate the performance of the business during the period compared to our previous expectations, along with any changes to our future projections, and update the estimated cash flows accordingly. In addition, we consider changes to our cost of capital and changes to the probability of achieving the earnout payment targets when updating our discount rate on a quarterly basis.
	The significant unobservable inputs used in the fair value measurements of our Level 3 contingent consideration liabilities were as follows:
		December 31,
		2014			2013
	Unobservable Input	(Weighted Average)
	Probability of achieving payout targets	79.1	%		70.6	%
	Discount rate	7.5	%		6.5	%
	A decrease in the assessed probabilities of achieving the targets or an increase in the discount rate, in isolation, would result in a lower fair value measurement. Changes in the values of the liabilities are recorded in Change in Fair Value of Contingent Consideration Liabilities within Other Expense (Income) on our Consolidated Statements of Income.
	Changes in the fair value of our contingent consideration obligations are as follows (in thousands):
	Balance as of January 1, 2013	$	90,009
	Contingent consideration liabilities recorded for business acquisitions	3,854
	Payments	(39,117		)
	Increase in fair value included in earnings	2,504
	Exchange rate effects	(1,597		)
	Balance as of December 31, 2013	$	55,653
	Contingent consideration liabilities recorded for business acquisitions	5,854
	Payments	(52,363		)
	Decrease in fair value included in earnings	(1,851		)
	Exchange rate effects	2
	Balance as of December 31, 2014	$	7,295
	The purchase price for our 2011 acquisition of Euro Car Parts Holdings Limited ("ECP") included contingent payments depending on the achievement of certain annual performance targets in 2012 and 2013. The performance target for each of the measurement periods was exceeded, and therefore, we settled the liabilities related to the 2012 and 2013 performance periods for the maximum amounts of £25 million and £30 million, respectively. During 2014, we settled the liability for the 2013 performance period through a cash payment of $44.8 million (£26.9 million) and the issuance of notes for $5.1 million (£3.1 million). The liability for the 2012 performance period was settled during the three months ended March 31, 2013, through a cash payment of $33.9 million (£22.4 million) and the issuance of notes for $3.9 million (£2.6 million). The cash payments made for the settlement of these contingent consideration liabilities are included within Payments of Other Obligations and Other cash outflows in the Cash Flows from Financing Activities and Cash Flows from Operating Activities sections, respectively, of our Consolidated Statements of Cash Flows.
	Substantially all of the gains and losses included in earnings during the years ended December 31, 2014 and 2013 related to contingent consideration obligations that were settled by December 31, 2014. The changes in the fair value of contingent consideration obligations included in earnings during 2014 and 2013 reflect the quarterly reassessment of each obligation's fair value, including an analysis of the significant inputs used in the valuation, as well as the accretion of the present value discount.
	Financial Assets and Liabilities Not Measured at Fair Value
	Our debt is reflected on the Consolidated Balance Sheets at cost. Based on market conditions as of December 31, 2014 and 2013, the fair value of our credit agreement borrowings reasonably approximated the carrying value of $1.1 billion and $673 million, respectively. In addition, based on market conditions, the fair value of the outstanding borrowings under the receivables facility reasonably approximated the carrying value of $94.9 million at December 31, 2014; we did not have any borrowings outstanding under the receivables facility as of December 31, 2013. As of December 31, 2014 and 2013, the fair value of our senior notes was approximately $569 million and $561 million, respectively, compared to a carrying value of $600 million.
	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 December 31, 2014 to assume these obligations. The fair value of our senior notes 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.

	Operating Leases
	We are obligated under noncancelable operating leases for corporate office space, warehouse and distribution facilities, trucks and certain equipment.
	The future minimum lease commitments under these leases at December 31, 2014 are as follows (in thousands):
	Years ending December 31:
	2015	$	138,670
	2016	121,263
	2017	100,363
	2018	81,635
	2019	65,001
	Thereafter	253,329
	Future Minimum Lease Payments	$	760,261
	Rental expense for operating leases was approximately $148.5 million, $122.4 million and $101.1 million during the years ended December 31, 2014, 2013 and 2012, respectively.
	We guarantee the residual values of the majority of our truck and equipment operating leases. 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 piece of equipment is sold, we would be responsible for a portion of the shortfall. Similarly, if the lessor realizes more than the residual value when a piece of equipment 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 December 31, 2014, our portion of the guaranteed residual value would have totaled approximately $29.0 million. We have not recorded a liability for the guaranteed residual value of equipment under operating leases as the recovery on disposition of the equipment under the leases is expected to approximate the guaranteed residual value.
	Litigation and Related Contingencies
	We were a plaintiff in a class action lawsuit against several aftermarket product suppliers. During 2012, we recognized gains totaling $17.9 million resulting from settlements with certain of the defendants. These gains were recorded as a reduction of Cost of Goods Sold on our Consolidated Statements of Income.
	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.

Business Combinations [Abstract]
Business Combinations	Business Combinations
	On January 3, 2014, we completed our acquisition of Keystone Specialty, which is a leading distributor and marketer of specialty vehicle aftermarket equipment and accessories in North America. Total acquisition date fair value of the consideration for our Keystone Specialty acquisition was $471.9 million, composed of $427.1 million of cash (net of cash acquired), $31.5 million of notes payable and $13.4 million of other purchase price obligations (non-interest bearing). We recorded $237.7 million of goodwill related to our acquisition of Keystone Specialty, which we do not expect to be deductible for income tax purposes. In the period between January 3, 2014 and December 31, 2014, Keystone Specialty generated approximately $771.1 million of revenue and $26.5 million of net income.
	In addition to our acquisition of Keystone Specialty, we made 22 acquisitions during 2014, including 9 wholesale businesses in North America, 9 wholesale businesses in Europe, 2 self service retail operations, and 2 specialty vehicle aftermarket businesses. Our European acquisitions included seven aftermarket parts distribution businesses in the Netherlands, five of which were customers of and distributors for our Netherlands subsidiary, Sator Beheer B.V. ("Sator"). Our European acquisitions were completed with the objective of aligning our Netherlands and U.K. distribution models; our other acquisitions completed during the year ended December 31, 2014 enabled us to expand into new product lines and enter new markets. Total acquisition date fair value of the consideration for these additional acquisitions was $359.1 million, composed of $334.3 million of cash (net of cash acquired), $13.5 million of notes payable, $0.3 million of other purchase price obligations (non-interest bearing), $5.9 million for the estimated value of contingent payments to former owners (with maximum potential payments totaling $8.3 million), and $5.1 million of pre-existing balances between us and the acquired entities considered to be effectively settled as a result of the acquisitions. During the year ended December 31, 2014, we recorded $178.0 million of goodwill related to these acquisitions and immaterial adjustments to preliminary purchase price allocations related to certain of our 2013 acquisitions. We expect $44.2 million of the $178.0 million of goodwill recorded to be deductible for income tax purposes. In the period between the acquisition dates and December 31, 2014, these acquisitions generated revenue of $257.8 million and $4.1 million of net income.
	On May 1, 2013, we acquired the shares of Sator, a vehicle mechanical aftermarket parts distribution company based in the Netherlands, with operations in the Netherlands, Belgium and Northern France. With the acquisition of Sator, we expanded our geographic presence in the European vehicle mechanical aftermarket products market into continental Europe to complement our existing U.K. operations. Total acquisition date fair value of the consideration for the acquisition of Sator was €209.8 million ($272.8 million) of cash, net of cash acquired. We recorded $142.7 million of goodwill related to our acquisition of Sator, which we do not expect will be deductible for income tax purposes.
	In addition to our acquisition of Sator, we made 19 acquisitions during 2013, including 10 wholesale businesses in North America, 7 wholesale businesses in Europe and 2 self service retail operations. Our European acquisitions included five automotive paint distribution businesses in the U.K., which enabled us to expand our collision product offerings. Our other acquisitions completed during 2013 enabled us to expand into new product lines and enter new markets. Total acquisition date fair value of the consideration for these additional 2013 acquisitions was $146.1 million, composed of $134.6 million of cash (net of cash acquired), $7.5 million of notes payable, $0.2 million of other purchase price obligations (non-interest bearing) and $3.9 million for the estimated value of contingent payments to former owners (with maximum potential payments totaling $5.0 million). During the year ended December 31, 2013, we recorded $92.7 million of goodwill related to these acquisitions and immaterial adjustments to preliminary purchase price allocations related to certain of our 2012 acquisitions. We expect $18.3 million of the $92.7 million of goodwill recorded to be deductible for income tax purposes.
	During the year ended December 31, 2012, we made 30 acquisitions in North America, including 22 wholesale businesses and 8 self service retail operations. These acquisitions enabled us to expand our geographic presence and enter new markets. Additionally, two of our acquisitions were completed with a goal of improving the recovery from scrap and other metals harvested from the vehicles we purchase: a precious metals refining and reclamation business and a scrap metal shredder. Total acquisition date fair value of the consideration for the 2012 acquisitions was $284.6 million, composed of $261.5 million of cash (net of cash acquired), $16.0 million of notes payable, $1.6 million of other purchase price obligations (non-interest bearing) and $5.5 million of contingent payments to former owners. The contingent consideration arrangements made in connection with our 2012 acquisitions have maximum potential payouts totaling $6.5 million. During the year ended December 31, 2012, we recorded $197.6 million of goodwill related to these acquisitions and immaterial adjustments to preliminary purchase price allocations related to certain of our 2011 acquisitions. We expect $157.8 million of the $197.6 million of goodwill recorded to be deductible for income tax purposes.
	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 market values at the dates of acquisition. In connection with the 2014 acquisitions, certain of the purchase price allocations 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 final estimation of 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.

	Included in other noncurrent liabilities recorded for our Sator acquisition is a liability for certain pension and other post-retirement obligations we assumed with the acquisition. Due to the immateriality of these plans, we have not provided the detailed disclosures otherwise prescribed by the accounting guidance on pensions and other post-retirement obligations.
	The primary reason for our acquisitions made in 2014, 2013 and 2012 was to create economic value for our stockholders by enhancing our position as a leading source for alternative collision and mechanical repair products and expanding into other product lines and businesses that may benefit from our operating strengths. Our acquisition of Keystone Specialty allows us to enter into new product lines and increase the size of our addressable market. In addition, we believe that the acquisition creates logistics and administrative cost synergies as well as cross-selling opportunities, which contributed to the goodwill recorded on the Keystone Specialty acquisition. Our other acquisitions enabled us to further expand our market presence, including continental Europe through the Sator acquisition, as well as to widen our product offerings such as paint and related equipment in the U.K. We believe that our Sator acquisition will allow for synergies within our European operations, most notably in procurement, warehousing and product management. These projected synergies contributed to the goodwill recorded on the Sator acquisition.
	When we identify potential acquisitions, we attempt to target companies with a leading market share, an experienced management team and workforce that provide 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 year ended December 31, 2014 as though the businesses had been acquired as of January 1, 2013, the businesses acquired during the year ended December 31, 2013 as though they had been acquired as of January 1, 2012 and the businesses acquired during the year ended December 31, 2012 as though they had been acquired as of January 1, 2011. The pro forma adjustments are based upon unaudited financial information of the acquired entities (in thousands, except per share data):

	(1) The sum of the individual earnings per share amounts may not equal the total due to rounding.
	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 net realizable value, adjustments to depreciation on acquired property 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 other acquisitions includes an adjustment for intercompany sales between Sator and the five Netherlands distributors that would have been reflected as intercompany transactions if the acquisitions had occurred on January 1, 2013. Our cost of sales in the initial months after the acquisitions reflects the increased valuation of acquired inventory, which has the impact of temporarily reducing our gross margin. Moving this negative gross margin impact to the year ended December 31, 2013 for our pro forma disclosure has the effect of increasing our pro forma net income during the year ended December 31, 2014. Additionally, the pro forma impact of our acquisitions reflects the elimination of acquisition related expenses totaling $3.2 million for the year ended December 31, 2014, primarily related to our May 2014 acquisitions of five aftermarket parts distribution businesses in the Netherlands. The pro forma impact of our Sator acquisition reflects the elimination of acquisition related expenses totaling $3.6 million for the year ended December 31, 2013. Additionally, the pro-forma impact of our other acquisitions reflects the elimination of acquisition related expenses totaling $2.2 million and $0.5 million for the years ended December 31, 2013 and 2012, respectively. Refer to Note 9, "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.

	Acquisition Related Expenses
	Acquisition related expenses, which include external costs such as legal, accounting and advisory fees, totaled $3.7 million, $6.7 million, and $0.5 million for the years ended December 31, 2014, 2013 and 2012, respectively. Our 2014 expenses included $1.9 million related to our acquisitions of seven aftermarket parts distribution businesses in the Netherlands; the remainder of our 2014 expenses related to our acquisition of a supplier of replacement parts, supplies and accessories for recreational vehicles in our Specialty segment as well as other completed and potential acquisitions. Our 2013 expenses included $3.6 million related to our acquisition of Sator in May 2013, $1.4 million related to our acquisitions of five U.K.-based paint distribution businesses, and $0.9 million related to our acquisition of Keystone Specialty in January 2014. These costs are expensed as incurred.
	Acquisition Integration Plans
	During the year ended December 31, 2014, we incurred $5.8 million of restructuring expenses as a result of the integration of our acquisition of Keystone Specialty into our existing business. These integration activities included the closure of duplicate facilities, termination of employees in connection with the consolidation of overlapping facilities with our existing business, and moving expenses. Future expenses to complete our integration plan are not expected to be material.
	Also during 2014, we incurred $1.9 million, $1.0 million, and $0.8 million of other restructuring costs related to our European, North American, and Specialty acquisitions, respectively. These costs are a result of activities to integrate our acquisitions into our existing business, including the closure of duplicate facilities, termination of employees in connection with the consolidation of overlapping facilities with our existing business, moving expenses, and other third party services directly related to our acquisitions.
	We expect to incur additional expenses related to the integration of certain of our acquisitions into our existing operations in 2015. These integration activities are expected to include the closure of duplicate facilities, termination of employees in connection with the consolidation of overlapping facilities with our existing business, and moving expenses. Future expenses to complete these integration plans are expected to be approximately $6 million.
	During the year ended December 31, 2013, we incurred $2.1 million of restructuring expenses related to the integration of certain of our 2013 European acquisitions and $1.4 million of restructuring expenses related to the integration of certain of our 2012 North American acquisitions. Integration costs during the year ended December 31, 2012 totaled $1.2 million. Our integration activities included the closure of duplicate facilities, termination of employees in connection with the consolidation of overlapping facilities with our existing business, moving expenses, and other third party services directly related to the integration of these acquisitions.
	European Restructuring Plan
	In the third quarter of 2014, we initiated restructuring activities to eliminate overlapping positions within certain of our European operations. As a result of these restructuring activities, we incurred $1.6 million of expenses during the year ended December 31, 2014, primarily for severance costs to terminated employees. While we do not expect material incremental expenses for this portion of the integration plan, we may incur additional expenses in the future as we continue to rationalize our European operations.
	Refurbished Bumper and Wheel Restructuring
	In the second quarter of 2012, we initiated a restructuring plan to improve the operational efficiency of our refurbished product operations and to reduce the cost structure of the related refurbished bumper and wheel product lines. As part of the restructuring plan, we consolidated certain of our bumper and wheel refurbishing operations, with a focus on increasing output at the remaining operations to improve economies of scale. Restructuring costs included the write off of disposed assets, severance costs for termination of overlapping headcount, costs to move equipment and inventory, and excess facility costs. These costs are expensed as incurred, when the costs meet the criteria to be accrued, or, in the case of non-performing lease reserves, at the cease-use date of the facility. During the year ended December 31, 2012, we incurred $1.1 million of expense related to this restructuring plan. These restructuring activities were substantially completed in 2012.

Diluted earnings per share incorporate the incremental shares issuable upon the assumed exercise of stock options and the assumed vesting of RSUs and restricted stock. Certain of our RSUs and stock options were excluded from the calculation of diluted earnings per share because they were antidilutive, but these equity instruments could be dilutive in the future.

	Undistributed earnings of the Company's foreign subsidiaries amounted to approximately $266 million at December 31, 2014. Those earnings are considered to be indefinitely reinvested, and accordingly no provision for U.S. income taxes has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to adjustment for foreign tax credits) and potential withholding taxes payable to the various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with its hypothetical calculation; however, unrecognized foreign tax credits would be available to reduce materially any U.S. liability.

	Our noncurrent deferred tax assets and current deferred tax liabilities are included in Other Assets and Other Current Liabilities, respectively, on our Consolidated Balance Sheets.
	We had net operating loss carryforwards for federal and certain of our state tax jurisdictions, the tax benefits of which total approximately $6.7 million and $5.1 million at December 31, 2014 and 2013, respectively. At December 31, 2014 and 2013, we had foreign, state, & local tax credit carryforwards of $4.4 million and $1.1 million, respectively. As of December 31, 2014 and 2013, valuation allowances of $5.2 million and $1.1 million, respectively, were recorded for a portion of the deferred tax assets related to net operating loss and tax credit carryforwards. Of the $4.1 million net increase in valuation allowances, $3.3 million was related to acquired foreign tax credit and net operating loss carryforwards, and the remainder was recognized primarily due to our judgment regarding the realization of other net operating loss and tax credit carryforwards.
The net operating loss carryforwards expire over the period from 2015 through 2033. Foreign tax credit carryforwards expire over the period from 2015 through 2024, while the state & local tax credits primarily have no expiration. Realization of these deferred tax assets is dependent on the generation of sufficient taxable income prior to the expiration dates. Based on historical and projected operating results, we believe that it is more likely than not that earnings will be sufficient to realize the deferred tax assets for which valuation allowances have not been provided. While we expect to realize the deferred tax assets, net of valuation allowances, changes in estimates of future taxable income or in tax laws may alter this expectation.
A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands):
	2014				2013				2012
Balance at January 1	$	1,445			$	1,693			$	4,305
Additions for acquired tax positions	2,322				—				—

Currency exchange rate fluctuations	(123		)		—				—
Balance at December 31	$	2,630			$	1,445			$	1,693
Included in the balance of unrecognized tax benefits above as of December 31, 2014, 2013 and 2012 are $1.9 million, $0.9 million and $1.1 million, respectively, of tax benefits that, if recognized, would affect the effective tax rate. The balance of unrecognized tax benefits at December 31, 2014, 2013 and 2012 also includes $0.7 million, $0.5 million, and $0.6 million respectively, of tax benefits that, if recognized, would result in adjustments to deferred taxes.
The Company recognizes interest and penalties accrued related to unrecognized tax benefits as income tax expense. Attributable to the unrecognized tax benefits noted above, at December 31, 2014 and 2013, the Company had accumulated interest and penalties of $0.7 million and $0.4 million respectively. During each of the years ended December 31, 2014, 2013, and 2012, $0.1 million, $0.1 million and $0.2 million, respectively, of interest and penalties were recorded through the income tax provision, prior to any reversals for lapses in the statutes of limitations.
During the twelve months beginning January 1, 2015, it is reasonably possible that we will reduce unrecognized tax benefits by up to approximately $0.1 million, all of which would impact our effective tax rate, primarily as a result of the expiration of certain statutes of limitations.
As of December 31, 2014, the U.S. Internal Revenue Service was conducting an examination of the Company’s Federal consolidated tax returns for 2011 and 2012. In the U.K., with limited exceptions, tax years through 2010 are no longer subject to inquiry. Certain Canadian operations are under examinations for the years 2010 to 2012. In the Netherlands, tax years through 2012 have been assessed. Tax years from 2011 are subject to income tax examinations by various U.S. state and local jurisdictions. Adjustments from such examinations, if any, are not expected to have a material effect on our financial position, results of operations or cash flows.

The remaining reclassification of unrealized gains and losses during these periods related to our foreign currency forward contracts and were recorded to other income in our Consolidated Statements of Income. These gains and losses offset the remeasurement of certain of our intercompany balances as discussed in Note 5, "Derivative Instruments and Hedging Activities." The deferred income taxes related to our cash flow hedges were reclassified from Accumulated Other Comprehensive Income to income tax expense.

	We have four operating segments: Wholesale – North America; Wholesale – Europe; Self Service; and Specialty. Our Specialty operating segment was formed with our January 3, 2014 acquisition of Keystone Specialty, as discussed in Note 8, "Business Combinations." 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. Therefore, we present three reportable segments: North America, Europe and Specialty.

	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 and administrative expenses are allocated to the segments based on usage, with shared expenses apportioned based on the segment's percentage of consolidated revenue. Segment EBITDA is calculated as EBITDA excluding restructuring and acquisition related expenses, change in fair value of contingent consideration liabilities and equity in earnings of unconsolidated subsidiaries. EBITDA, which is the basis for Segment EBITDA, is calculated as net income excluding depreciation, amortization, interest (including loss on debt extinguishment) and taxes. Loss on debt extinguishment is considered a component of interest in calculating EBITDA, as the write-off of debt issuance costs is similar to the treatment of debt issuance cost amortization.

	LKQ Corporation (the "Parent") issued, and certain of its 100% owned subsidiaries (the "Guarantors") have fully and unconditionally guaranteed, jointly and severally, the Company's Notes 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 Notes; (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 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 Notes; (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 Notes; and (iv) upon legal defeasance, covenant defeasance or satisfaction and discharge of the Indenture, as defined in the Indenture.
	Presented below are the condensed consolidating financial statements of the Parent, the Guarantors, the non-guarantor subsidiaries (the "Non-Guarantors"), and the elimination entries necessary to present the Company's 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 Notes. 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 revenues and expenses. The condensed consolidating financial statements below have been prepared from the Company's financial information on the same basis of accounting as the 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.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of LKQ Corporation and its subsidiaries. All intercompany transactions and accounts have been eliminated.
Use of Estimates	Use of Estimates
	In preparing our financial statements in conformity with accounting principles generally accepted in the United States, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition
	The majority of our revenue is derived from the sale of vehicle parts. Revenue is recognized when the products are shipped to, delivered to or picked up by customers and title has transferred, subject to an allowance for estimated returns, discounts and allowances that we estimate based upon historical information. We recorded a reserve for estimated returns, discounts and allowances of approximately $31.3 million and $26.6 million at December 31, 2014 and 2013, respectively. We present taxes assessed by governmental authorities collected from customers on a net basis. Therefore, the taxes are excluded from revenue on our Consolidated Statements of Income and are shown as a current liability on our Consolidated Balance Sheets until remitted. We recognize revenue from the sale of scrap, cores and other metals when title has transferred, which typically occurs upon delivery to the customer. Revenue also includes amounts billed to customers for shipping and handling. Distribution expenses in the accompanying Consolidated Statements of Income are the costs incurred to prepare and deliver products to customers.
Receivables and Allowance for Doubtful Accounts	Receivables and Allowance for Doubtful Accounts
	In the normal course of business, we extend credit to customers after a review of each customer's credit history. We recorded a reserve for uncollectible accounts of approximately $19.4 million and $14.4 million at December 31, 2014 and 2013, respectively. The reserve is based upon the aging of the accounts receivable, our assessment of the collectability of specific customer accounts and historical experience. Receivables are written off once collection efforts have been exhausted. Recoveries of receivables previously written off are recorded when received.
Concentrations of Credit Risk	Concentrations of Credit Risk
	Financial instruments that potentially subject us to significant concentration of credit risk consist primarily of cash and equivalents and accounts receivable. We control our exposure to credit risk associated with these instruments by (i) placing our cash and equivalents with several major financial institutions; (ii) holding high-quality financial instruments; and (iii) maintaining strict policies over credit extension that include credit evaluations, credit limits and monitoring procedures. In addition, our overall credit risk with respect to accounts receivable is limited to some extent because our customer base is composed of a large number of geographically diverse customers
Inventory	Inventory
	We classify our inventory into the following categories: aftermarket and refurbished products; and salvage and remanufactured products.
	An aftermarket product is a new vehicle product manufactured by a company other than the original equipment manufacturer. Cost is established based on the average price we pay for parts, and includes expenses incurred for freight and overhead costs. For items purchased from foreign companies, import fees and duties and transportation insurance are also included. Refurbished inventory cost is based on the average price we pay for cores, which are recycled automotive parts that are not suitable for sale as a replacement part without further processing. The cost of our refurbished inventory also includes expenses incurred for freight, labor and other overhead.
	A salvage product is a recycled vehicle part suitable for sale as a replacement part. Cost is established based upon the price we pay for a vehicle, including auction, storage and towing fees, as well as expenditures for buying and dismantling. Inventory carrying value is determined using the average cost to sales percentage at each of our facilities and applying that percentage to the facility's inventory at expected selling prices, the assessment of which incorporates the sales probability based on a part's days in stock and historical demand. The average cost to sales percentage is derived from each facility's historical profitability for salvage vehicles. Remanufactured inventory cost is based upon the price paid for cores, and also includes expenses incurred for freight, direct manufacturing costs and overhead.
	For all inventory, carrying value is recorded at the lower of cost or market and is reduced to reflect current anticipated demand. If actual demand differs from our estimates, additional reductions to inventory carrying value would be necessary in the period such determination is made.
	Inventory consists of the following (in thousands):
		December 31,
		2014			2013
	Aftermarket and refurbished products	$	1,022,549		$	706,600
	Salvage and remanufactured products	411,298			370,352
		$	1,433,847		$	1,076,952
	Our acquisitions completed during 2014 and adjustments to preliminary valuations of inventory for certain of our 2013 acquisitions contributed $253.7 million of the increase in our aftermarket and refurbished products inventory and $20.8 million of the increase in our salvage and remanufactured products inventory during 2014. See Note 8, "Business Combinations" for further information on our acquisitions.
Property and Equipment	Property and Equipment
	Property and equipment are recorded at cost less accumulated depreciation. Expenditures for major additions and improvements that extend the useful life of the related asset are capitalized. As property and equipment are sold or retired, the applicable cost and accumulated depreciation are removed from the accounts and any resulting gain or loss thereon is recognized. Construction in progress consists primarily of building and land improvements at our existing facilities. Depreciation is calculated using the straight-line method over the estimated useful lives or, in the case of leasehold improvements, the term of the related lease and reasonably assured renewal periods, if shorter.
	Our estimated useful lives are as follows:
	Land improvements	10-20 years
	Buildings and improvements	20-40 years
	Furniture, fixtures and equipment	3-20 years
	Computer equipment and software	3-10 years
	Vehicles and trailers	3-10 years
	Property and equipment consists of the following (in thousands):
		December 31,
		2014			2013
	Land and improvements	$	112,582		$	101,018
	Buildings and improvements	173,366			143,535
	Furniture, fixtures and equipment	337,125			282,862
	Computer equipment and software	125,888			108,424
	Vehicles and trailers	87,944			64,381

	Construction in progress	38,064			31,989
		$	629,987		$	546,651
	We record depreciation expense within Depreciation and Amortization on our Consolidated Statements of Income. Additionally, included in Cost of Goods Sold on the Consolidated Statements of Income is depreciation expense associated with our refurbishing, remanufacturing, and furnace operations and our distribution centers. Total depreciation expense for the years ended December 31, 2014, 2013 and 2012 was $90.9 million, $72.7 million, and $60.7 million, respectively.
Intangible Assets	Intangible Assets
	Intangible assets consist primarily of goodwill (the cost of purchased businesses in excess of the fair value of the identifiable net assets acquired) and other specifically identifiable intangible assets, such as trade names, trademarks, customer relationships, software and other technology related assets, and covenants not to compete.
	Goodwill is tested for impairment at least annually, and we performed annual impairment tests during the fourth quarters of 2014, 2013 and 2012. The results of all of these tests indicated that goodwill was not impaired.
	The changes in the carrying amount of goodwill by reportable segment are as follows (in thousands):
		North America			Europe			Specialty		Total
	Balance as of January 1, 2012	$	1,136,630		$	339,433		$	—	$	1,476,063

	Balance as of December 31, 2014	$	1,392,032		$	616,819		$	280,044	$	2,288,895
	In 2014 and 2013, we finalized the valuation of certain intangible assets acquired related to our 2013 and 2012 acquisitions, respectively. As these adjustments did not have a material impact on our financial position or results of operations, we recorded these adjustments to goodwill and amortization expense in 2014 and 2013, respectively.
	The components of other intangibles are as follows (in thousands):

	During 2014, we recorded $35.5 million of trade names, $65.1 million of customer relationships, $26.7 million of software and technology related assets and $1.9 million of covenants not to compete resulting from our 2014 acquisitions and adjustments to certain preliminary intangible asset valuations from our 2013 acquisitions. The trade names, customer relationships, and software and technology related assets recorded in 2014 included $22.0 million, $30.5 million, and $25.5 million, respectively, related to our acquisition of Keystone Specialty as discussed in Note 8, "Business Combinations." Other intangible assets resulting from our acquisition of Keystone Specialty were not material. We also recognized trade names and customer relationships of $10.1 million and $17.6 million, respectively, related to our 2014 acquisition of a supplier of replacement parts, supplies and accessories for recreational vehicles in our Specialty segment and customer relationships of $12.0 million related to our 2014 acquisition of an automotive core business.
	During 2013, we recorded $23.9 million of trade names, $14.1 million of customer relationships, $19.3 million of software and technology related assets and $0.3 million of covenants not to compete resulting from our 2013 acquisitions and adjustments to certain preliminary intangible asset valuations from our 2012 acquisitions. The trade names, customer relationships, and software and technology related assets recorded in 2013 included $23.5 million, $2.5 million, and $19.3 million, respectively, related to our acquisition of Sator Beheer B.V. ("Sator") as discussed in Note 8, "Business Combinations." We also recognized $11.4 million of customer relationships related to our acquisitions of five automotive paint distributors in 2013.
	Trade names and trademarks are amortized over a useful life ranging from 10 to 30 years on a straight-line basis. Customer relationships are amortized over the expected period to be benefited (5 to 20 years) on an accelerated basis. Software and other technology related assets are amortized on a straight-line basis over the expected period to be benefited (five to six years). Covenants not to compete are amortized over the lives of the respective agreements, which range from one to five years, on a straight-line basis. The weighted average amortization period for our intangible assets acquired during 2014 is 14 years. Amortization expense for intangibles was $34.5 million, $13.8 million and $9.5 million during the years ended December 31, 2014, 2013 and 2012, respectively. Estimated amortization expense for each of the five years in the period ending December 31, 2019 is $33.1 million, $30.0 million, $27.6 million, $22.4 million and $17.8 million, respectively.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. There were no material adjustments to the carrying value of long-lived assets during the years ended December 31, 2014, 2013 or 2012.
Warranty Reserve	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 that is supported by certain of the suppliers of those products. We record the estimated warranty costs at the time of sale using historical warranty claim information to project future warranty claims activity. The changes in the warranty reserve are as follows (in thousands):
	Balance as of January 1, 2013	$	10,574
	Warranty expense	29,674
	Warranty claims	(27,801		)
	Balance as of December 31, 2013	$	12,447
	Warranty expense	30,370
	Warranty claims	(27,936		)
	Balance as of December 31, 2014	$	14,881
Self-Insurance Reserves	Self-Insurance Reserves
	We self-insure a portion of employee medical benefits under the terms of our employee health insurance program. We purchase certain stop-loss insurance to limit our liability exposure. We also self-insure a portion of our property and casualty risk, which includes automobile liability, general liability, directors and officers liability, workers' compensation, and property coverage, under deductible insurance programs. The insurance premium costs are expensed over the contract periods. A reserve for liabilities associated with these losses is established for claims filed and claims incurred but not yet reported based upon our estimate of ultimate cost, which is calculated using analyses of historical data. We monitor new claims and claim development as well as trends related to the claims incurred but not reported in order to assess the adequacy of our insurance reserves. Total self-insurance reserves were $76.0 million and $55.6 million, including $36.4 million and $25.8 million classified as Other Accrued Expenses, as of December 31, 2014 and 2013, respectively. The remaining balances of self-insurance reserves are classified as Other Noncurrent Liabilities, which reflects management's estimates of when claims will be paid. The reserves presented on the Consolidated Balance Sheets are net of claims deposits of $0.6 million and $0.5 million at December 31, 2014 and 2013, respectively. In addition to these claims deposits, we had outstanding letters of credit of $59.2 million and $43.0 million at December 31, 2014 and 2013, respectively, to guarantee self-insurance claims payments. While we do not expect the amounts ultimately paid to differ significantly from our estimates, our insurance reserves and corresponding expenses could be affected if future claims experience differs significantly from historical trends and assumptions.
Income Taxes	Income Taxes
	Current income taxes are provided on income reported for financial reporting purposes, adjusted for transactions that do not enter into the computation of income taxes payable in the same year. Deferred income taxes have been provided to show the effect of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefit or that future deductibility is uncertain.
	We recognize the benefits of uncertain tax positions taken or expected to be taken in tax returns in the provision for income taxes only for those positions that are more likely than not to be realized. We follow a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. Our policy is to include interest and penalties associated with income tax obligations in income tax expense.
	U.S. federal income taxes are not provided on our interest in undistributed earnings of foreign subsidiaries when it is management's intent that such earnings will remain invested in those subsidiaries or other foreign subsidiaries. Taxes will be provided on these earnings in the period in which a decision is made to repatriate the earnings.
Investment in Unconsolidated Subsidiary	Investment in Unconsolidated Subsidiary
	As of December 31, 2014, the carrying value of our investments in unconsolidated subsidiaries was $8.1 million; of this amount, $6.4 million relates to our investment in ACM Parts Pty Ltd ("ACM Parts"). In August 2013, we entered into an agreement with Suncorp Group, a leading general insurance group in Australia and New Zealand, to develop ACM Parts, an alternative vehicle replacement parts business in those countries. We hold a 49% interest in the entity and are contributing our experience to help establish automotive parts recycling operations and to facilitate the procurement of aftermarket parts; Suncorp Group holds a 51% equity interest and is supplying salvage vehicles to the venture as well as assisting in establishing relationships with repair shops as customers. We are accounting for our interest in this subsidiary using the equity method of accounting, as our investment gives us the ability to exercise significant influence, but not control, over the investee. The total of our investment in ACM Parts and other unconsolidated subsidiaries is included within Other Assets on our Consolidated Balance Sheets. Our equity in the net earnings of the investees for the years ended December 31, 2014 and 2013 was not material.
Rental Expense	Rental Expense
	We recognize rental expense on a straight-line basis over the respective lease terms, including reasonably assured renewal periods, for all of our operating leases.
Foreign Currency Translation	Foreign Currency Translation
	For most of our foreign operations, the local currency is the functional currency. Assets and liabilities are translated into U.S. dollars at the period-ending exchange rate. Statements of Income amounts are translated to U.S. dollars using average exchange rates during the period. Translation gains and losses are reported as a component of Accumulated Other Comprehensive Income (Loss) in stockholders' equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). This update outlines a new comprehensive revenue recognition model which supersedes most current revenue recognition guidance, and requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities adopting the standard have the option of using either a full retrospective or modified retrospective approach in the application of this guidance. ASU 2014-09 will be effective for the Company during the first quarter of our fiscal year 2017. Early adoption is not permitted. We are still evaluating the impact that ASU 2014-09 will have on our consolidated financial statements and related disclosures.
	In June 2014, the FASB issued Accounting Standards Update 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period" ("ASU 2014-12"). This update requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition, and requires the recognition of compensation cost in the period in which it becomes probable that the performance target will be achieved. ASU 2014-12 will be effective for the Company during the first quarter of our fiscal year 2016. Early adoption is permitted. The new standard can be applied either prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements as an adjustment to opening retained earnings. We do not anticipate the adoption of this update will have a material impact on our financial position, results of operations, cash flows, or disclosures.
