Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Operating Leases Our lease obligations consist primarily of real estate office space with terms up to 11 years. Certain leases contain escalation clauses and renewal options, and generally our leases have no residual value guarantees or material covenants. We exclude from our balance sheet leases with a term equal to one year or less and do not separate non-lease components from our real estate leases. Rent expense under operating leases was $38 million and variable lease costs were insignificant for the year ended December 31, 2019. At December 31, 2019, operating lease right-of-use assets, included in other assets, were $137 million and operating lease liabilities, included in other liabilities, were $158 million. Operating lease right-of-use assets obtained in exchange for lease obligations were $36 million for the year ended December 31, 2019. At December 31, 2019, our undiscounted future lease obligations related to operating leases having initial terms in excess of one year were $27 million, $27 million, $25 million, $21 million, $20 million, and $67 million for the years 2020, 2021, 2022, 2023, 2024 and thereafter, with imputed interest of $29 million at December 31, 2019. The weighted average discount rate was 4.4% and the weighted average remaining lease term was 7.9 years at December 31, 2019. Lease agreements that have not yet commenced were insignificant at December 31, 2019. Concentrations of Credit Risk Financial instruments which potentially subject us to concentrations of credit risk are primarily cash equivalents, restricted cash, derivative financial instruments and retail finance receivables. Our cash equivalents and restricted cash represent investments in highly rated securities placed through various major financial institutions. The counterparties to our derivative financial instruments are various major financial institutions. Borrowers located in Texas accounted for 12.5% of the retail finance receivable portfolio at December 31, 2019. No other state or country accounted for more than 10% of the retail finance receivable portfolio. At December 31, 2019, substantially all of our commercial finance receivables represent loans to GM-franchised dealers and their affiliates. Guarantees of Indebtedness At December 31, 2019 and 2018, we guaranteed approximately $561 million and $1.1 billion in aggregate principal amount of Euro Medium Term Notes issued by General Motors Financial International B.V., our former subsidiary, pursuant to our Euro Medium Term Note Programme. Subject to the terms and conditions of a letter agreement with BNP Paribas in connection with the sale of our European Operations, BNP Paribas will reimburse us for any amount that we may pay under any such guarantees. Legal Proceedings We are subject to various pending and potential legal and regulatory proceedings in the ordinary course of business, including litigation, arbitration, claims, investigations, examinations, subpoenas and enforcement proceedings. Some litigation against us could take the form of class actions. The outcome of these proceedings are inherently uncertain, and thus we cannot confidently predict how or when proceedings will be resolved. An adverse outcome in one or more of these proceedings could result in substantial damages, settlements, fines, penalties, diminished income or reputational harm. We identify below the material proceedings in connection with which we believe a material loss is reasonably possible or probable. In accordance with the current accounting standards for loss contingencies, we establish reserves for legal matters when it is probable that a loss associated with the matter has been incurred and the amount of the loss can be reasonably estimated. The actual costs of resolving legal matters may be higher or lower than any amounts reserved for these matters. At December 31, 2019, we estimated our reasonably possible legal exposure for unfavorable outcomes is up to $53 million, and have accrued $19 million. In 2014 and 2015, we were served with investigative subpoenas from various state attorneys general and other governmental offices to produce documents and data relating to our automobile loan and lease business and securitization of loans and leases. We believe that we have cooperated fully with all reasonable requests for information. We are currently unable to estimate any reasonably possible loss or range of loss that may result from these investigations. Other Administrative Tax Matters We accrue non-income tax liabilities for contingencies when management believes that a loss is probable and the amounts can be reasonably estimated, while contingent gains are recognized only when realized. In the event any losses are sustained in excess of accruals, they will be charged against income at that time. In evaluating indirect tax matters, we take into consideration factors such as our historical experience with matters of similar nature, specific facts and circumstances, and the likelihood of prevailing. We reevaluate and update our accruals as matters progress over time. Where there is a reasonable possibility that losses exceeding amounts already recognized may be incurred, our estimate of the additional range of loss is up to $13 million as of December 31, 2019.
