Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Financial Statements	Interim Financial Statements LKQ Corporation, a Delaware corporation, is a holding company and all operations are conducted by subsidiaries. When the terms "LKQ," "the Company," "we," "us," or "our" are used in this document, those terms refer to LKQ Corporation and its consolidated subsidiaries. We have prepared the accompanying Unaudited Condensed Consolidated Financial Statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") applicable to interim financial statements. Accordingly, certain information related to our significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted. These Unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all material adjustments (which include only normally recurring adjustments) necessary to fairly state, in all material respects, our financial position, results of operations and cash flows for the periods presented. We have reclassified certain prior period amounts to conform to the current period presentation. Results for interim periods are not necessarily indicative of the results that can be expected for any subsequent interim period or for a full year. These interim financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 22, 2024 ("2023 Form 10-K"). Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements During the first quarter of 2023, we adopted Accounting Standards Update No. 2022-04, “Liabilities—Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations” ("ASU 2022-04"), which requires the buyer in a supplier finance program to disclose certain information about its program, including key terms, balance sheet presentation of amounts, outstanding amounts at the end of each period, and rollforwards of balances. We adopted the provisions of ASU 2022-04 on a retrospective basis (see Note 11, "Supply Chain Financing"), except for the disclosure of rollforward information, which will be adopted prospectively in our Annual Report on Form 10-K for the year ending December 31, 2024 as required. The adoption of ASU 2022-04 did not have a material impact on our unaudited condensed consolidated financial statements. Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board issued Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU is effective on a retrospective basis for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements. In December 2023, the Financial Accounting Standards Board issued Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). The ASU requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. The ASU will be effective for fiscal years beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements.
