Organization Consolidation And Presentation Of Financial Statements [Abstract]
Background and Basis of Presentation	Note 1. Background and Basis of Presentation Background Garrett Motion Inc. (the “Company” or “Garrett”) designs, manufactures and sells highly engineered turbocharger and electric-boosting technologies for light and commercial vehicle original equipment manufacturers (“OEMs”) and the global vehicle independent aftermarket, as well as automotive software solutions. We are a global technology leader with significant expertise in delivering products across gasoline and diesel propulsion systems and hybrid and fuel cell powertrains. On October 1, 2018, the Company became an independent publicly-traded company through a pro rata distribution by Honeywell International Inc. (“Former Parent” or “Honeywell”) of 100% of the then-outstanding shares of Garrett to Honeywell’s stockholders (the “Spin-Off”). Each Honeywell stockholder of record received one share of Garrett common stock for every 10 shares of Honeywell common stock held on the record date. Approximately 74 million shares of Garrett common stock were distributed on October 1, 2018 to Honeywell stockholders. In connection with the Spin-Off, Garrett´s common stock began trading “regular-way” under the ticker symbol “GTX” on the New York Stock Exchange on October 1, 2018. The Spin-Off was completed pursuant to a Separation and Distribution Agreement and other agreements with Honeywell related to the Spin-Off, including but not limited to an indemnification and reimbursement agreement (the “Indemnification and Reimbursement Agreement”) and a tax matters agreement (the “Tax Matters Agreement”). Refer to Note 17, Commitments and Contingencies for additional details related to the Indemnification and Reimbursement Agreement and Tax Matters Agreement. Unless the context otherwise requires, references to “Garrett,” “we,” “us,” “our,” and “the Company” refer to (i) Honeywell’s Transportation Systems Business (the “Transportation Systems Business” or the “Business”) prior to the Spin-Off and (ii) Garrett Motion Inc. and its subsidiaries following the Spin-Off, as applicable. Basis of Presentation Prior to the Spin-Off on October 1, 2018, our historical financial statements were prepared on a stand-alone combined basis and were derived from the consolidated financial statements and accounting records of Honeywell. Accordingly, for periods prior to October 1, 2018, our financial statements are presented on a combined basis and for the periods subsequent to October 1, 2018 are presented on a consolidated basis (collectively, the historical financial statements for all periods presented are referred to as “Consolidated and Combined Interim Financial Statements”). The Consolidated and Combined Interim Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Asbestos-related expenses, net of probable insurance recoveries, are presented within Other expense, net in the Consolidated and Combined Interim Statement of Operations. Honeywell is subject to certain asbestos-related and environmental-related liabilities, primarily related to its legacy Bendix business. In conjunction with the Spin-Off, certain operations that were part of the Bendix business, along with the ownership of the Bendix trademark, as well as certain operations that were part of other legacy elements of the Business, were transferred to us. For the periods prior to the Spin-Off, these Consolidated and Combined Interim Financial Statements reflect an estimated liability for resolution of pending and future asbestos-related and environmental liabilities primarily related to the legacy Bendix business, calculated as if we were responsible for 100% of the Bendix asbestos-liability payments. However, this recognition model differs from the recognition model applied subsequent to the Spin-Off, with the difference recognized through equity as of the Spin-Off date. In periods subsequent to the Spin-Off, the accounting for the majority of our asbestos-related liability payments and accounts payable reflect the terms of the Indemnification and Reimbursement Agreement with Honeywell entered into on September 12, 2018, under which we are required to make payments to Honeywell in amounts equal to 90% of Honeywell’s asbestos-related liability payments and accounts payable, primarily related to the Bendix business in the United States, as well as certain environmental-related liability payments and accounts payable and non-United States asbestos-related liability payments and accounts payable, in each case related to legacy elements of the Business, including the legal costs of defending and resolving such liabilities, less 90% of Honeywell’s net insurance receipts and, as may be applicable, certain other recoveries associated with such liabilities. The Indemnification and Reimbursement Agreement provides that the agreement will terminate upon the earlier of (x) December 31, 2048 or (y) December 31st of the third consecutive year during which certain amounts owed to Honeywell during each such year were less than $25 million as converted into Euros in accordance with the terms of the agreement. The Consolidated and Combined Interim Financial Statements are unaudited; however, in the opinion of management, they contain all the adjustments (consisting of those of a normal recurring nature) considered necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP applicable to interim periods. The Consolidated and Combined Interim Financial Statements should be read in conjunction with the audited annual Consolidated and Combined Financial Statements for the year ended December 31, 2018 included in our Annual Report on Form 10-K, as filed with the SEC on March 1, 2019 (our “2018 Form 10-K”). The results of operations for the three and nine months ended September 30, 2019 and cash flows for the nine months ended September 30, 2019 should not necessarily be taken as indicative of the entire year. We report our quarterly financial information using a calendar convention: the first, second and third quarters are consistently reported as ending on March 31, June 30 and September 30. It has been our practice to establish actual quarterly closing dates using a predetermined fiscal calendar, which requires our businesses to close their books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on our business processes. The effects of this practice are generally not significant to reported results for any quarter and only exist within a reporting year. For differences in actual closing dates that are material to year-over-year comparisons of quarterly or year-to-date results, such differences have been adjusted for the three months ended September 30, 2019. Our actual closing dates for the three months ended September 30, 2019 and 2018 were September 28, 2019 and September 29, 2018, respectively.

Basis of Presentation

Prior to the Spin-Off on October 1, 2018, our historical financial statements were prepared on a stand-alone combined basis and were derived from the consolidated financial statements and accounting records of Honeywell. Accordingly, for periods prior to October 1, 2018, our financial statements are presented on a combined basis and for the periods subsequent to October 1, 2018 are presented on a consolidated basis (collectively, the historical financial statements for all periods presented are referred to as “Consolidated and Combined Interim Financial Statements”). The Consolidated and Combined Interim Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Asbestos-related expenses, net of probable insurance recoveries, are presented within Other expense, net in the Consolidated and Combined Interim Statement of Operations. Honeywell is subject to certain asbestos-related and environmental-related liabilities, primarily related to its legacy Bendix business. In conjunction with the Spin-Off, certain operations that were part of the Bendix business, along with the ownership of the Bendix trademark, as well as certain operations that were part of other legacy elements of the Business, were transferred to us.
