Nature of Operations and Basis of Presentation [Abstract]

Nature of Operations and Basis of Presentation

General Motors Company (sometimes referred to in this Quarterly Report on Form 10-Q as we, our, us, ourselves, the Company, General Motors or GM) designs, builds and sells trucks, crossovers, cars and automobile parts worldwide and is investing in and growing an autonomous vehicle business. We also provide automotive financing services through General Motors Financial Company, Inc. (GM Financial). We analyze the results of our continuing operations through the following operating segments: GM North America (GMNA), GM International Operations (GMIO), GM South America (GMSA), GM Cruise and GM Financial. Our GMSA and GMIO operating segments are reported as one, combined international segment, GM International (GMI). GM Cruise is our global segment responsible for the development and commercialization of autonomous vehicle technology. Nonsegment operations and Maven, our ride- and car-sharing business, are classified as Corporate. Corporate includes certain centrally recorded income and costs such as interest, income taxes, corporate expenditures and certain nonsegment-specific revenues and expenses.

The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements include all adjustments, which consist of normal recurring adjustments and transactions or events discretely impacting the interim periods, considered necessary by management to fairly state our results of operations, financial position and cash flows. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2018 Form 10-K. Except for per share amounts or as otherwise specified, dollar amounts presented within tables are stated in millions. In the three months ended March 31, 2019 we changed the presentation of our condensed consolidated balance sheets to reclassify the current portion of Equipment on operating leases, net to Other current assets and our condensed consolidated statements of cash flows to reclassify Payments to purchase common stock to Other financing activities. We have made corresponding reclassifications to the comparable information for all periods presented.

Principles of Consolidation We consolidate entities that we control due to ownership of a majority voting interest and we consolidate variable interest entities (VIEs) when we are the primary beneficiary. Our share of earnings or losses of nonconsolidated affiliates is included in our consolidated operating results using the equity method of accounting when we are able to exercise significant influence over the operating and financial decisions of the affiliate.

Recently Adopted Accounting Standards

Effective January 1, 2019, we adopted Accounting Standards Update (ASU) 2016-02, "Leases" (ASU 2016-02) using the modified retrospective method, resulting in a cumulative-effect adjustment to the opening balance of Retained earnings for an insignificant amount. We recognized $1.0 billion of right of use assets and lease obligations included in Other assets, Accrued liabilities and Other liabilities on our condensed consolidated balance sheet for our existing operating lease portfolio at January 1, 2019. We elected to apply the practical expedient related to land easements, as well as the package of practical expedients permitted under the transition guidance in the new standard, which allowed us to carry forward our historical lease classification. The accounting for our finance leases and leases where we are the lessor remained substantially unchanged. The application of ASU 2016-02 had no impact on our condensed consolidated income statement or condensed consolidated statement of cash flows.

The following table summarizes our minimum commitments under noncancelable operating leases having initial terms in excess of one year, primarily for property, at December 31, 2018 as disclosed in our 2018 Form 10-K:



	Years Ending December 31,
	2019			2020			2021			2022			2023			Thereafter			Total
Minimum commitments(a)	$	296		$	286		$	247		$	180		$	146		$	582		$	1,737
Sublease income	(61		)	(51		)	(44		)	(38		)	(33		)	(129		)	(356		)
Net minimum commitments	$	235		$	235		$	203		$	142		$	113		$	453		$	1,381

_________


(a)	Certain leases contain escalation clauses and renewal or purchase options.

Refer to Note 13 for information on our operating leases at June 30, 2019.

Accounting Standards Not Yet Adopted

In June 2016 the Financial Accounting Standards Board issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" (ASU 2016-13), which requires entities to use a new impairment model based on Current Expected Credit Losses (CECL) rather than incurred losses. We plan to adopt ASU 2016-13 on January 1, 2020 on a modified retrospective basis, which will result in an increase to our allowance for credit losses and a decrease to Retained earnings as of the adoption date. Estimated credit losses under CECL will consider relevant information about past events, current conditions and reasonable and supportable forecasts that affect the collectibility of the reported amount, resulting in recognition of lifetime expected credit losses upon loan origination. We are currently testing and refining our process to calculate credit losses in accordance with ASU 2016-13 that, once completed, will determine the impact on our condensed consolidated financial statements at the date of adoption. We expect to be substantially complete with our implementation efforts before December 31, 2019.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Adjustments to sales incentives for previously recognized sales were insignificant and decreased revenue by $482 million in the three months ended June 30, 2019 and 2018.

Contract liabilities in our Automotive segments consist primarily of maintenance, extended warranty and other service contracts. We recognized revenue of $469 million and $902 million related to contract liabilities in the three and six months ended June 30, 2019 and $402 million and $785 million in the three and six months ended June 30, 2018. We expect to recognize revenue of $846 million in the six months ending December 31, 2019 and $689 million, $403 million and $465 million in the years ending December 31, 2020, 2021 and thereafter related to contract liabilities at June 30, 2019.

Our investment in Lyft, Inc. (Lyft) is estimated at fair value using Level 3 inputs because the investment is subject to transfer restrictions. The fair value of our investment in Lyft at June 30, 2019 uses Lyft’s quoted market price, less a discount for the lack of marketability due to the restriction from selling our shares until September 26, 2019. The estimated volatility rate represents the significant unobservable input to the put option pricing model used to derive the fair value of our investment. The fair value of this investment was $1.1 billion included in Other current assets and $884 million included in Other assets at June 30, 2019 and December 31, 2018. We recorded an unrealized loss of $65 million and an unrealized gain of $220 million in Interest income and other non-operating income, net in the three and six months ended June 30, 2019 and an unrealized gain of $142 million in the three and six months ended June 30, 2018.

Retail Finance Receivables We use proprietary scoring systems in the underwriting process that measure the credit quality of retail finance receivables using several factors, such as credit bureau information, consumer credit risk scores (e.g., FICO score or its equivalent) and contract characteristics. We also consider other factors such as employment history, financial stability and capacity to pay. Subsequent to origination we review the credit quality of retail finance receivables based on customer payment activity. At June 30, 2019 and December 31, 2018, 23% and 25% of retail finance receivables were from consumers with sub-prime credit scores, which are defined as a FICO score or its equivalent of less than 620 at the time of loan origination.

An account is considered delinquent if a substantial portion of a scheduled payment has not been received by the date the payment was contractually due. The accrual of finance charge income had been suspended on delinquent retail finance receivables with contractual amounts due of $838 million and $888 million at June 30, 2019 and December 31, 2018. The following table summarizes the contractual amount of delinquent retail finance receivables, which is not significantly different than the recorded investment of the retail finance receivables:



	June 30, 2019				June 30, 2018

Total finance receivables more than 30 days delinquent or in repossession	$	1,629	3.8	%	$	1,697	4.8	%

Commercial Finance Receivables Our commercial finance receivables consist of dealer financings, primarily for inventory purchases. Proprietary models are used to assign a risk rating to each dealer. We perform periodic credit reviews of each dealership and adjust the dealership's risk rating, if necessary. Dealers in Group VI are subject to additional restrictions on funding, including suspension of lines of credit and liquidation of assets. The commercial finance receivables on non-accrual status were insignificant at June 30, 2019 and December 31, 2018. The following table summarizes the credit risk profile by dealer risk rating of the commercial finance receivables:

Variable Interest Entities [Abstract]

Variable Interest Entities

GM Financial uses special purpose entities (SPEs) that are considered VIEs to issue variable funding notes to third party bank-sponsored warehouse facilities or asset-backed securities to investors in securitization transactions. The debt issued by these VIEs is backed by finance receivables and leasing related assets transferred to the VIEs (Securitized Assets). GM Financial determined that it is the primary beneficiary of the SPEs because the servicing responsibilities for the Securitized Assets give GM Financial the power to direct the activities that most significantly impact the performance of the VIEs and the variable interests in the VIEs give GM Financial the obligation to absorb losses and the right to receive residual returns that could potentially be significant. The assets serve as the sole source of repayment for the debt issued by these entities. Investors in the notes issued by the VIEs do not have recourse to GM Financial or its other assets, with the exception of customary representation and warranty repurchase provisions and indemnities that GM Financial provides as the servicer. GM Financial is not required and does not currently intend to provide additional financial support to these SPEs. While these subsidiaries are included in GM Financial's condensed consolidated financial statements, they are separate legal entities and their assets are legally owned by them and are not available to GM Financial's creditors.

The following table summarizes the assets and liabilities related to GM Financial's consolidated VIEs:



	June 30, 2019		December 31, 2018
Restricted cash – current	$	2,098	$	1,876
Restricted cash – non-current	$	490	$	504

GM Financial short-term debt and current portion of long-term debt	$	20,604	$	21,087
GM Financial long-term debt	$	20,241	$	21,417

GM Financial recognizes finance charge, leased vehicle and fee income on the Securitized Assets and interest expense on the secured debt issued in a securitization transaction and records a provision for loan losses to recognize probable loan losses inherent in the finance receivables.

Commitments and Contingencies	6 Months Ended
Commitments and Contingencies	Jun. 30, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation-Related Liability and Tax Administrative Matters In the normal course of our business, we are named from time to time as a defendant in various legal actions, including arbitrations, class actions and other litigation. We identify below the material individual proceedings and investigations where we believe a material loss is reasonably possible or probable. We accrue for matters when we believe that losses are probable and can be reasonably estimated. At June 30, 2019 and December 31, 2018, we had accruals of $1.4 billion and $1.3 billion in Accrued liabilities and Other liabilities. In many matters, it is inherently difficult to determine whether loss is probable or reasonably possible or to estimate the size or range of the possible loss. Accordingly, adverse outcomes from such proceedings could exceed the amounts accrued by an amount that could be material to our results of operations or cash flows in any particular reporting period. Proceedings Related to Ignition Switch Recall and Other Recalls In 2014 we announced various recalls relating to safety and other matters. Those recalls included recalls to repair ignition switches that could under certain circumstances unintentionally move from the “run” position to the “accessory” or “off” position with a corresponding loss of power, which could in turn prevent airbags from deploying in the event of a crash. Economic-Loss Claims We are aware of over 100 putative class actions pending against GM in U.S. and Canadian courts alleging that consumers who purchased or leased vehicles manufactured by GM or Motors Liquidation Company (MLC), formerly known as General Motors Corporation, had been economically harmed by one or more of the 2014 recalls and/or the underlying vehicle conditions associated with those recalls (economic-loss cases). In general, these economic-loss cases seek recovery for purported compensatory damages, such as alleged benefit-of-the-bargain damages or damages related to alleged diminution in value of the vehicles, as well as punitive damages, injunctive relief and other relief. Many of the pending U.S. economic-loss claims have been transferred to, and consolidated in, a single federal court, the U.S. District Court for the Southern District of New York (Southern District). These plaintiffs have asserted economic-loss claims under federal and state laws, including claims relating to recalled vehicles manufactured by GM and claims asserting successor liability relating to certain recalled vehicles manufactured by MLC. In August 2017 the Southern District granted our motion to dismiss the successor liability claims of plaintiffs in seven of the sixteen states at issue on the motion and called for additional briefing to decide whether plaintiffs' claims can proceed in the other nine states. In December 2017, the Southern District granted GM's motion and dismissed the plaintiffs' successor liability claims in an additional state, but found that there are genuine issues of material fact that prevent summary judgment for GM in eight other states. In January 2018, GM moved for reconsideration of certain portions of the Southern District's December 2017 summary judgment ruling. That motion was granted in April 2018, dismissing plaintiffs' successor liability claims in any state where New York law applies. In September 2018, the Southern District granted our motion to dismiss claims for lost personal time (in 41 out of 47 jurisdictions) and certain unjust enrichment claims, but denied our motion to dismiss plaintiffs’ economic loss claims in 27 jurisdictions under the "manifest defect" rule. Significant summary judgment, class certification, and expert evidentiary motions remain at issue. Personal Injury Claims We also are aware of several hundred actions pending in various courts in the U.S. and Canada alleging injury or death as a result of defects that may be the subject of the 2014 recalls (personal injury cases). In general, these cases seek recovery for purported compensatory damages, punitive damages and/or other relief. Since 2016, several bellwether trials of personal injury cases have taken place in the Southern District and in a Texas state court, which is administering a Texas state multi-district litigation. None of these trials resulted in a finding of liability against GM. Appellate Litigation Regarding Successor Liability Ignition Switch Claims In 2016, the United States Court of Appeals for the Second Circuit held that the 2009 order of the United States Bankruptcy Court for the Southern District of New York (Bankruptcy Court) approving the sale of substantially all of the assets of MLC to GM free and clear of, among other things, claims asserting successor liability for obligations owed by MLC could not be enforced to bar claims against GM asserted by either plaintiffs who purchased used vehicles after the sale or against purchasers who asserted claims relating to the ignition switch defect, including pre-sale personal injury claims and economic-loss claims. Contingently Issuable Shares Under the Amended and Restated Master Sale and Purchase Agreement between us and MLC, GM may be obligated to issue additional shares (Adjustment Shares) of our common stock if allowed general unsecured claims against the MLC GUC Trust (GUC Trust), as estimated by the Bankruptcy Court, exceed $35.0 billion. The maximum number of Adjustment Shares issuable is 30 million shares (subject to adjustment to take into account stock dividends, stock splits and other transactions), which amounts to approximately $1.2 billion based on the GM share price as of July 15, 2019. The GUC Trust stated in public filings that allowed general unsecured claims were approximately $31.9 billion at March 31, 2019. In 2016 and 2017, certain personal injury and economic loss plaintiffs filed motions in the Bankruptcy Court seeking authority to file late claims against the GUC Trust. In May 2018, the GUC Trust filed motions seeking the Bankruptcy Court’s approval of a proposed settlement with certain personal injury and economic loss plaintiffs, approval of a notice relating to that proposed settlement and estimation of alleged personal injury and economic loss late claims for the purpose of obtaining an order requiring GM to issue the maximum number of Adjustment Shares. GM vigorously contested each of these motions. In September 2018 the Bankruptcy Court denied without prejudice the GUC Trust’s motions described above, finding that the settling parties first need to obtain class certification with respect to the economic loss late claims. In February 2019, the GUC Trust and certain plaintiffs filed a motion with the Bankruptcy Court requesting approval of a new settlement to obtain the maximum number of Adjustment Shares. In March 2019, we asserted several legal objections to this new settlement. We are unable to estimate any reasonably possible loss or range of loss that may result from this matter. Government Matters In connection with the 2014 recalls, we have from time to time received subpoenas and other requests for information related to investigations by agencies or other representatives of U.S. federal, state and the Canadian governments. GM is cooperating with all reasonable pending requests for information. Any existing governmental matters or investigations could in the future result in the imposition of damages, fines, civil consent orders, civil and criminal penalties or other remedies. The total amount accrued for the 2014 recalls at June 30, 2019 reflects amounts for a combination of settled but unpaid matters, and for the remaining unsettled investigations, claims and/or lawsuits relating to the ignition switch recalls and other related recalls to the extent that such matters are probable and can be reasonably estimated. The amounts accrued for those unsettled investigations, claims, and/or lawsuits represent a combination of our best single point estimates where determinable and, where no such single point estimate is determinable, our estimate of the low end of the range of probable loss with regard to such matters, if that is determinable. We will continue to consider resolution of pending matters involving ignition switch recalls and other recalls where it makes sense to do so. GM Korea Wage Litigation GM Korea is party to litigation with current and former hourly employees in the appellate court and Incheon District Court in Incheon, Korea. The group actions, which in the aggregate involve more than 10,000 employees, allege that GM Korea failed to include bonuses and certain allowances in its calculation of Ordinary Wages due under Korean regulations. In 2012, the Seoul High Court (an intermediate level appellate court) affirmed a decision in one of these group actions involving five GM Korea employees which was contrary to GM Korea's position. GM Korea appealed to the Supreme Court of the Republic of Korea (Supreme Court). In 2014, the Supreme Court largely agreed with GM’s legal arguments and remanded the case to the Seoul High Court for consideration consistent with earlier Supreme Court precedent holding that while fixed bonuses should be included in the calculation of Ordinary Wages, claims for retroactive application of this rule would be barred under certain circumstances. In 2015, on reconsideration, the Seoul High Court held in GM Korea’s favor, after which the plaintiffs appealed to the Supreme Court. The Supreme Court has not yet rendered a decision. We estimate our reasonably possible loss in excess of amounts accrued to be approximately $590 million at June 30, 2019. Both the scope of claims asserted and GM Korea's assessment of any or all of the individual claim elements may change if new information becomes available or the legal or regulatory frameworks change. GM Korea is also party to litigation with current and former salaried employees over allegations relating to ordinary wages regulation and whether to include fixed bonuses in the calculation of ordinary wages. In 2017, the Seoul High Court held that certain workers are not barred from filing retroactive wage claims. GM Korea appealed this ruling to the Supreme Court. The Supreme Court has not yet rendered a decision. We estimate our reasonably possible loss in excess of amounts accrued to be approximately $160 million at June 30, 2019. Both the scope of claims asserted and GM Korea's assessment of any or all of the individual claim elements may change if new information becomes available or the legal or regulatory frameworks change. GM Korea is also party to litigation with current and former subcontract workers over allegations that they are entitled to the same wages and benefits provided to full-time employees, and to be hired as full-time employees. In May 2018 the Korean labor authorities issued an adverse administrative order finding that GM Korea must hire certain current subcontract workers as full-time employees. GM Korea appealed that order. At June 30, 2019, our accrual covering certain asserted claims and claims that we believe are probable of assertion and for which liability is probable was insignificant. We estimate the reasonably possible loss in excess of amounts accrued for other current subcontract workers who may assert similar claims to be approximately $140 million at June 30, 2019. We are currently unable to estimate any possible loss or range of loss that may result from additional claims that may be asserted by former subcontract workers. GM Brazil Indirect Tax Claim In February 2019, the Superior Judicial Court of Brazil rendered a favorable decision on a case brought by GM Brazil, challenging whether a certain state value-added tax should be included in the calculation of federal gross receipts taxes. The decision will allow the Company the right to recover, through offset of federal tax liabilities, amounts collected by the government from October 2007 to December 2014. As a result of the favorable decision, we recorded pre-tax recoveries of $857 million to Automotive and other cost of sales in the three months ended March 31, 2019. In April 2019, the Superior Judicial Court of Brazil rendered a favorable decision on another GM Brazil case, granting us the right to recover tax amounts collected by the government from August 2001 to September 2007. We recorded pre-tax recoveries of $380 million in the three months ended June 30, 2019. Timing on realization of these recoveries is dependent upon the timing of administrative approvals and generation of federal tax liabilities eligible for offset. The retrospective right to recover for other periods remains under judicial review, and a decision could be rendered in 2019. If the Superior Judicial Court of Brazil grants retrospective recovery right for the other periods, we estimate additional potential pre-tax recoveries of up to $100 million. Other Litigation-Related Liability and Tax Administrative Matters Various other legal actions, including class actions, governmental investigations, claims and proceedings are pending against us or our related companies or joint ventures, including matters arising out of alleged product defects; employment-related matters; product and workplace safety, vehicle emissions and fuel economy regulations; product warranties; financial services; dealer, supplier and other contractual relationships; government regulations relating to competition issues; tax-related matters not subject to the provision of Accounting Standards Codification 740, Income Taxes (indirect tax-related matters); product design, manufacture and performance; consumer protection laws; and environmental protection laws, including laws regulating air emissions, water discharges, waste management and environmental remediation from stationary sources. There are several putative class actions pending against GM in federal courts in the U.S., the Provincial Courts in Canada and Israel alleging that various vehicles sold, including model year 2011-2016 Duramax Diesel Chevrolet Silverado and GMC Sierra vehicles, violate federal, state and foreign emission standards. GM has also faced a series of additional lawsuits based primarily on allegations in the Duramax suit, including putative shareholder class actions claiming violations of federal securities law and a shareholder demand lawsuit. The securities lawsuits have been voluntarily dismissed. At this stage of these proceedings, we are unable to provide an evaluation of the likelihood that a loss will be incurred or an estimate of the amounts or range of possible loss. We believe that appropriate accruals have been established for losses that are probable and can be reasonably estimated. It is possible that the resolution of one or more of these matters could exceed the amounts accrued in an amount that could be material to our results of operations. We also from time to time receive subpoenas and other inquiries or requests for information from agencies or other representatives of U.S. federal, state and foreign governments on a variety of issues. Indirect tax-related matters are being litigated globally pertaining to value added taxes, customs, duties, sales, property taxes and other non-income tax related tax exposures. The various non-U.S. labor-related matters include claims from current and former employees related to alleged unpaid wage, benefit, severance and other compensation matters. Certain administrative proceedings are indirect tax-related and may require that we deposit funds in escrow or provide an alternative form of security which may range from $200 million to $500 million at June 30, 2019. Some of the matters may involve compensatory, punitive or other treble damage claims, environmental remediation programs or sanctions that, if granted, could require us to pay damages or make other expenditures in amounts that could not be reasonably estimated at June 30, 2019. We believe that appropriate accruals have been established for losses that are probable and can be reasonably estimated. For indirect tax-related matters we estimate our reasonably possible loss in excess of amounts accrued to be up to approximately $950 million at June 30, 2019. Takata Matters In May 2016, the National Highway Traffic Safety Administration (NHTSA) issued an amended consent order requiring Takata to file defect information reports (DIRs) for previously unrecalled front airbag inflators that contain phased-stabilized ammonium nitrate-based propellant without a moisture absorbing desiccant on a multi-year, risk-based schedule through 2019 impacting tens of millions of vehicles produced by numerous automotive manufacturers. NHTSA concluded that the likely root cause of the rupturing of the airbag inflators is a function of time, temperature cycling and environmental moisture. Although we do not believe there is a safety defect at this time in any unrecalled GM vehicles within scope of the Takata DIRs, in cooperation with NHTSA we have filed Preliminary DIRs covering certain of our GMT900 vehicles, which are full-size pickup trucks and sport utility vehicles (SUVs). We have also filed petitions for inconsequentiality with respect to the vehicles subject to those Preliminary DIRs. NHTSA has consolidated our petitions and will rule on them at the same time. While these petitions have been pending, we have provided NHTSA with the results of our long-term studies and the studies performed by third-party experts, all of which form the basis for our determination that the inflators in these vehicles do not present an unreasonable risk to safety and that no repair should ultimately be required. We believe these vehicles are currently performing as designed and our inflator aging studies and field data support the belief that the vehicles' unique design and integration mitigates against inflator propellant degradation and rupture risk. For example, the airbag inflators used in the vehicles are a variant engineered specifically for our vehicles, and include features such as greater venting, unique propellant wafer configurations, and machined steel end caps. The inflators are packaged in the instrument panel in such a way as to minimize exposure to moisture from the climate control system. Also, these vehicles have features that minimize the maximum temperature to which the inflator will be exposed, such as larger interior volumes and standard solar absorbing windshields and side glass. Accordingly, no warranty provision has been made for any repair associated with our vehicles subject to the Preliminary DIRs and amended consent order. However, in the event we are ultimately obligated to repair the vehicles subject to current or future Takata DIRs under the amended consent order in the U.S., we estimate a reasonably possible impact to GM of approximately $1.2 billion. GM has recalled certain vehicles sold outside of the U.S. to replace Takata inflators in those vehicles. There are significant differences in vehicle and inflator design between the relevant vehicles sold internationally and those sold in the U.S. We continue to gather and analyze evidence about these inflators and to share our findings with regulators. Additional recalls, if any, could be material to our results of operations and cash flows. We continue to monitor the international situation. Through July 15, 2019 we are aware of five putative class actions filed against GM in federal court in the U.S., one putative class action in Mexico, one putative class action in Israel and three putative class actions pending in various Provincial Courts in Canada arising out of allegations that airbag inflators manufactured by Takata are defective. At this early stage of these proceedings, we are unable to provide an evaluation of the likelihood that a loss will be incurred or an estimate of the amounts or range of possible loss. Product Liability We recorded liabilities of $532 million and $531 million in Accrued liabilities and Other liabilities at June 30, 2019 and December 31, 2018 for the expected cost of all known product liability claims, plus an estimate of the expected cost for product liability claims that have already been incurred and are expected to be filed in the future for which we are self-insured. It is reasonably possible that our accruals for product liability claims may increase in future periods in material amounts, although we cannot estimate a reasonable range of incremental loss based on currently available information. Other than claims relating to the ignition switch recalls discussed above, we believe that any judgment against us involving our and General Motors Corporation products for actual damages will be adequately covered by our recorded accruals and, where applicable, excess liability insurance coverage. Guarantees We enter into indemnification agreements for liability claims involving products manufactured primarily by certain joint ventures. These guarantees terminate in years ranging from 2019 to 2024 or upon the occurrence of specific events or are ongoing. We believe that the related potential costs incurred are adequately covered by our recorded accruals, which are insignificant. The maximum future undiscounted payments mainly based on vehicles sold to date were $2.6 billion and $2.4 billion for these guarantees at June 30, 2019 and December 31, 2018, the majority of which relates to the indemnification agreements. We provide payment guarantees on commercial loans outstanding with third parties such as dealers. In some instances, certain assets of the party or our payables to the party whose debt or performance we have guaranteed may offset, to some degree, the amount of any potential future payments. We are also exposed to residual value guarantees associated with certain sales to rental car companies. We periodically enter into agreements that incorporate indemnification provisions in the normal course of business. It is not possible to estimate our maximum exposure under these indemnifications or guarantees due to the conditional nature of these obligations. Insignificant amounts have been recorded for such obligations as the majority of them are not probable or estimable at this time and the fair value of the guarantees at issuance was insignificant. Refer to Note 18 for additional information on our indemnification obligations to Peugeot, S.A. (PSA Group) under the Master Agreement (the Agreement). Operating Leases Our portfolio of leases consists primarily of real estate office space, manufacturing and warehousing facilities, land and equipment. Certain leases contain escalation clauses and renewal or purchase options, and generally our leases have no residual value guarantees or material covenants. We exclude leases with a term of one year or less from our balance sheet, and do not separate non-lease components from our real estate leases. Rent expense under operating leases was $96 million and $182 million in the three and six months ended June 30, 2019. Variable lease costs were insignificant in the three and six months ended June 30, 2019. At June 30, 2019 operating lease right of use assets in Other assets were $956 million, operating lease liabilities in Accrued liabilities were $231 million and non-current operating lease liabilities in Other liabilities were $824 million. Operating lease right of use assets obtained in exchange for lease obligations were $163 million in the six months ended June 30, 2019. Our undiscounted future lease obligations related to operating leases having initial terms in excess of one year are $140 million for the six months ending December 31, 2019 and $242 million, $214 million, $147 million, $133 million and $342 million for the years 2020, 2021, 2022, 2023 and thereafter, with imputed interest of $163 million as of June 30, 2019. The weighted average discount rate was 4.5% and the weighted-average remaining lease term was 6.0 years at June 30, 2019. Payments for operating leases included in Net cash provided by (used in) operating activities were $175 million in the six months ended June 30, 2019. As of June 30, 2019 we entered into lease agreements, mainly for office space, that have not yet commenced with gross future lease obligations of $379 million.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim income tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2009 to 2018 with various significant tax jurisdictions. In the three months ended June 30, 2019 Income tax expense of $524 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation, partially offset by tax benefits related to tax settlements. In the three months ended June 30, 2018 Income tax expense of $519 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. In the six months ended June 30, 2019 Income tax expense of $661 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation, partially offset by tax benefits related to a release of valuation allowance, tax settlements and benefits from foreign dividends. In the six months ended June 30, 2018 Income tax expense of $985 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. At June 30, 2019 we had $23.2 billion of net deferred tax assets consisting of net operating losses and income tax credits, capitalized research expenditures and other timing differences that are available to offset future income tax liabilities, partially offset by valuation allowances.

Restructuring and Related Activities [Abstract]

Restructuring and Other Initiatives

We have executed various restructuring and other initiatives and we may execute additional initiatives in the future, if necessary, to streamline manufacturing capacity and reduce other costs to improve the utilization of remaining facilities. To the extent these programs involve voluntary separations, a liability is generally recorded at the time offers to employees are accepted. To the extent these programs provide separation benefits in accordance with pre-existing agreements, a liability is recorded once the amount is probable and reasonably estimable. If employees are involuntarily terminated, a liability is generally recorded at the communication date. Related charges are recorded in Automotive and other cost of sales and Automotive and other selling, general and administrative expense. The following table summarizes the reserves and charges related to restructuring and other initiatives, including postemployment benefit reserves and charges:

We recorded charges of $361 million, primarily in GMNA, in the three months ended June 30, 2019 consisting of $231 million primarily in supplier-related charges, which are reflected in the table above, and $130 million primarily in non-cash accelerated depreciation, not reflected in the table above. We recorded charges of $1.2 billion, primarily in GMNA, in the six months ended June 30, 2019 consisting of $911 million primarily in non-cash accelerated depreciation, not reflected in the table above, and $240 million primarily in supplier-related charges, which are reflected in the table above. These programs have a total cost since inception of $2.5 billion and we expect to incur additional restructuring and other charges in the six months ending December 31, 2019 that range from $500 million to $1.1 billion, primarily related to employee-related separation charges, accelerated depreciation and supplier-related charges. We incurred $487 million in cash outflows resulting from these restructuring actions, primarily for employee separation payments, in the six months ended June 30, 2019. We expect additional cash outflows related to these activities of approximately $1.3 billion to be substantially complete by the end of 2020.

In the three and six months ended June 30, 2018 restructuring and other initiatives primarily included the closure of a facility and other restructuring actions in Korea. We recorded charges of $132 million and $1.0 billion in Korea in GMI, net of noncontrolling interests in the three and six months ended June 30, 2018. These charges consisted of $73 million primarily in supplier claims and $537 million in non-cash asset impairments and other charges, not reflected in the table above, and $59 million and $495 million in employee separation charges, which are reflected in the table above, in the three and six months ended June 30, 2018. We incurred $676 million in cash outflows in the six months ended June 30, 2018 and $775 million in cash outflows in the year ended December 31, 2018 resulting from these Korea restructuring actions primarily for employee separations and statutory pension payments. These programs were substantially complete at December 31, 2018.

Stockholders' Equity and Noncontrolling Interests

Stockholders' Equity Note [Abstract]

Stockholders' Equity and Noncontrolling Interests

We had 2.0 billion shares of preferred stock and 5.0 billion shares of common stock authorized for issuance and 1.4 billion shares of common stock issued and outstanding at June 30, 2019 and December 31, 2018.

GM Cruise Preferred Shares In May 2019, GM Cruise Holdings LLC (GM Cruise Holdings), our subsidiary, entered into a Purchase Agreement with SoftBank Vision Fund (AIV M2), L.P. (The Vision Fund), General Motors Holdings LLC, Honda Motor Co., Ltd. (Honda), and certain other investors pursuant to which GM Cruise Holdings received $1.1 billion in exchange for issuing Class F Preferred Shares (GM Cruise Class F Preferred Shares), including $687 million from General Motors Holdings LLC, representing approximately 6.4% of the fully diluted equity of GM Cruise Holdings. In July 2019, regulatory approval was received resulting in an additional insignificant amount becoming due from The Vision Fund. All proceeds related to the GM Cruise Class F Preferred Shares are designated exclusively for working capital and general corporate purposes of GM Cruise. The GM Cruise Class F Preferred Shares participate pari passu with holders of GM Cruise Holdings common stock in any dividends declared. The GM Cruise Class F Preferred Shares have the right to vote on the election of one director, who is elected by the vote of a majority of the GM Cruise Holdings common stock and the GM Cruise Class F Preferred Shares. Prior to an initial public offering, the holders of GM Cruise Class F Preferred Shares are restricted from transferring the GM Cruise Class F Preferred Shares until May 7, 2023. The GM Cruise Class F Preferred Shares only convert into common stock of GM Cruise Holdings, at specified exchange ratios, upon occurrence of an initial public offering. No covenants or other events of default that can trigger redemption of the Class F Preferred Shares exist. The GM Cruise Class F Preferred Shares are entitled to receive the greater of their carrying value or a pro-rata share of any proceeds or distributions upon the occurrence of a merger, sale, liquidation, or dissolution of GM Cruise Holdings. The GM Cruise Class F Preferred Shares are classified as noncontrolling interests in our condensed consolidated financial statements. As of June 30, 2019, external investors held 17.1% of the fully diluted equity in GM Cruise Holdings.

In June 2018, GM Cruise Holdings issued $900 million of convertible preferred shares (GM Cruise Preferred Shares) to an affiliate of The Vision Fund which subsequently assigned such shares to The Vision Fund. Immediately prior to the issuance of the GM Cruise Preferred Shares, we invested $1.1 billion in GM Cruise Holdings. When GM Cruise's autonomous vehicles are ready for commercial deployment, The Vision Fund is obligated to purchase additional GM Cruise Preferred Shares for $1.35 billion. All proceeds are designated exclusively for working capital and general corporate purposes of GM Cruise. Dividends are cumulative and accrue at an annual rate of 7% and are payable quarterly in cash or in-kind, at GM Cruise's discretion. The GM Cruise Preferred Shares are also entitled to participate in GM Cruise dividends above a defined threshold. Prior to an initial public offering, The Vision Fund is restricted from transferring the GM Cruise Preferred Shares until June 28, 2025. The GM Cruise Preferred Shares are classified as noncontrolling interests in our condensed consolidated financial statements.

GM Korea Preferred Shares In May 2018, the Korea Development Bank (KDB) agreed to purchase approximately $750 million of GM Korea’s Class B Preferred Shares from GM Korea (GM Korea Preferred Shares), $361 million of which was received in June 2018 with the remainder received in the three months ended December 31, 2018. Dividends on the GM Korea Preferred Shares are cumulative and accrue at an annual rate of 1%. GM Korea can call the preferred shares at their original issue price six years from the date of issuance and once called, the preferred shares can be converted into common shares of GM Korea at the option of the holder. The KDB investment can only be used for purposes of funding capital expenditures in GM Korea. The GM Korea Preferred Shares are classified as noncontrolling interests in our condensed consolidated financial statements. In conjunction with the GM Korea Preferred Share issuance we agreed to provide GM Korea future funding, if needed, not to exceed $2.8 billion through December 31, 2027, inclusive of $2.0 billion of planned capital expenditures through 2027.

Discontinued Operations

Discontinued Operations and Disposal Groups [Abstract]

Discontinued Operations

On July 31, 2017 we closed the sale of the Opel and Vauxhall businesses and certain other assets in Europe (the Opel/Vauxhall Business) to PSA Group. On October 31, 2017 we closed the sale of the European financing subsidiaries and branches (the Fincos, and together with the Opel/Vauxhall Business, the European Business) to Banque PSA Finance S.A. and BNP Paribas Personal Finance S.A. Our wholly owned subsidiary (the Seller) agreed to indemnify PSA Group for certain losses resulting from any inaccuracy of the representations and warranties or breaches of our covenants included in the Agreement and for certain other liabilities including certain emissions and product liabilities. The Company entered into a guarantee for the benefit of PSA Group and pursuant to which the Company agreed to guarantee the Seller's obligation to indemnify PSA Group. Certain of these indemnification obligations are subject to time limitations, thresholds and/or caps as to the amount of required payments.

Although the sale reduced our new vehicle presence in Europe, we may still be impacted by actions taken by regulators related to vehicles sold before the sale. In Germany, the Kraftfahrt-Bundesamt (KBA) issued an order in October 2018, which would convert Opel’s existing voluntary recall of certain vehicles into a mandatory recall for allegedly failing to comply with certain emissions regulations. In addition, at the KBA's request, the German authorities re-opened a separate criminal investigation that had previously been closed with no action. Opel is challenging the mandatory recall order of the KBA in court on the grounds that the emission control systems contained in the subject vehicles have at all times complied with the regulations in place when the vehicles were manufactured, tested, approved and sold.

In 2017 and 2018, Opel initiated a voluntarily recall/service campaign for many of these vehicles and such voluntary actions remain ongoing while Opel’s challenge of the mandatory recall remains pending. Opel’s voluntary recall and service actions have been undertaken at its own expense, and this expense should not be transferred to the Seller because it was accounted for at the time of the sale. However, the Seller may be obligated to indemnify PSA Group for certain additional expenses resulting from any mandatory recall that might be ordered to be implemented, as well as related potential litigation costs, settlements, judgments and potential fines. We are unable to estimate any reasonably possible loss or range of loss that may result from this matter.

We continue to purchase from and supply to PSA Group certain vehicles, parts and engineering services for a period of time following closing. The following table summarizes transactions with the Opel/Vauxhall Business:



	Three Months Ended				Six Months Ended

Segment Reporting [Abstract]

Segment Reporting

We analyze the results of our business through the following reportable segments: GMNA, GMI, GM Cruise and GM Financial. The chief operating decision maker evaluates the operating results and performance of our automotive segments and GM Cruise through earnings before interest and taxes (EBIT)-adjusted, which is presented net of noncontrolling interests. The chief operating decision maker evaluates GM Financial through earnings before income taxes (EBT)-adjusted because interest income and interest expense are part of operating results when assessing and measuring the operational and financial performance of the segment. Each segment has a manager responsible for executing our strategic initiatives. While not all vehicles within a segment are individually profitable on a fully allocated cost basis, those vehicles attract customers to dealer showrooms and help maintain sales volumes for other, more profitable vehicles and contribute towards meeting required fuel efficiency standards. As a result of these and other factors, we do not manage our business on an individual brand or vehicle basis.

Substantially all of the trucks, crossovers, cars and automobile parts produced are marketed through retail dealers in North America and through distributors and dealers outside of North America, the substantial majority of which are independently owned. In addition to the products sold to dealers for consumer retail sales, trucks, crossovers and cars are also sold to fleet customers, including daily rental car companies, commercial fleet customers, leasing companies and governments. Fleet sales are completed through the dealer network and in some cases directly with fleet customers. Retail and fleet customers can obtain a wide range of after-sale vehicle services and products through the dealer network, such as maintenance, light repairs, collision repairs, vehicle accessories and extended service warranties.

GMNA meets the demands of customers in North America with vehicles developed, manufactured and/or marketed under the Buick, Cadillac, Chevrolet and GMC brands. GMI primarily meets the demands of customers outside North America with vehicles developed, manufactured and/or marketed under the Buick, Cadillac, Chevrolet, GMC, and Holden brands. We also have equity ownership stakes in entities that meet the demands of customers in other countries, primarily China, with vehicles developed, manufactured and/or marketed under the Baojun, Buick, Cadillac, Chevrolet, Jiefang and Wuling brands. GM Cruise is our global segment responsible for the development and commercialization of autonomous vehicle technology, and includes autonomous vehicle-related engineering and other costs.

Our automotive operations' interest income and interest expense, Maven, legacy costs from the Opel/Vauxhall Business (primarily pension costs), corporate expenditures and certain nonsegment-specific revenues and expenses are recorded centrally in Corporate. Corporate assets consist primarily of cash and cash equivalents, marketable securities, our investment in Lyft, PSA warrants, Maven vehicles and intercompany balances. Retained net underfunded pension liabilities related to the European Business are also recorded in Corporate. All intersegment balances and transactions have been eliminated in consolidation.

The following tables summarize key financial information by segment:
