Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies In 2006, the Company completed the spin-offs of its Realogy and Wyndham subsidiaries. The Company does not believe that the impact of any resolution of pre-existing contingent liabilities in connection with the spin-offs should result in a material liability to the Company in relation to its consolidated financial position or liquidity, as Realogy and Wyndham each have agreed to assume responsibility for these liabilities. The Company is also named in litigation that is primarily related to the businesses of its former subsidiaries, including Realogy and Wyndham. The Company is entitled to indemnification from such entities for any liability resulting from such litigation. In February 2017, following a state court trial in Georgia, a jury found the Company liable for damages in a case brought by a plaintiff who was injured in a vehicle accident allegedly caused by an employee of an independent contractor of the Company who was acting outside of the scope of employment. In fourth quarter 2019, the Company appealed both verdicts resulting in a reversal of the opinions rendered. The plaintiffs filed a petition to have the Georgia Supreme Court review the state appellate court’s reversal of the opinion, which petition has been granted. The Company has recognized a liability related to these cases, net of recoverable insurance proceeds, of approximately $12 million. The Company is currently involved, and in the future may be involved, in claims, legal proceedings and governmental inquiries that are incidental to its vehicle rental and car sharing operations, including, among others, contract and licensee disputes, competition matters, employment and wage-and-hour claims, insurance and liability claims, intellectual property claims, business practice disputes and other regulatory, environmental, commercial and tax matters. Litigation is inherently unpredictable and, although the Company believes that its accruals are adequate and/or that it has valid defenses in these matters, unfavorable resolutions could occur. The Company estimates that the potential exposure resulting from adverse outcomes of current legal proceedings in which it is reasonably possible that a loss may be incurred could, in the aggregate, be up to approximately $40 million in excess of amounts accrued as of September 30, 2020. The Company does not believe that the impact should result in a material liability to the Company in relation to its consolidated financial condition or results of operations. Commitments to Purchase Vehicles The Company maintains agreements with vehicle manufacturers under which the Company has agreed to purchase approximately $3.4 billion of vehicles from manufacturers over the next 12 months, a $4.3 billion decrease compared to December 31, 2019, financed primarily through the issuance of vehicle-backed debt and cash received upon the disposition of vehicles. Certain of these commitments are subject to the vehicle manufacturers satisfying their obligations under their respective repurchase and guaranteed depreciation agreements. Concentrations Concentrations of credit risk at September 30, 2020 include (i) risks related to the Company’s repurchase and guaranteed depreciation agreements with domestic and foreign car manufacturers, primarily with respect to receivables for program cars that have been disposed but for which the Company has not yet received payment from the manufacturers and (ii) risks related to Realogy and Wyndham, including receivables of $25 million and $15 million, respectively, related to certain contingent, income tax and other corporate liabilities assumed by Realogy and Wyndham in connection with their disposition.
