Nature of Operations and Basis of Presentation [Abstract]
Nature of Operations and Basis of Presentation	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 cars, trucks, crossovers and automobile parts worldwide. 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 segments: GM North America (GMNA), GM International Operations (GMIO), GM South America (GMSA) and GM Financial. 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 including autonomous vehicle-related engineering costs and certain nonsegment specific revenues and expenses. On July 31, 2017 we closed the sale of the Opel and Vauxhall business and certain other assets in Europe (the Opel/Vauxhall Business) to Peugeot S.A. (PSA Group). Both the Opel/Vauxhall Business and our European financing subsidiaries and branches (the Fincos, and together with the Opel/Vauxhall Business, the European Business) are presented as discontinued operations in our condensed consolidated financial statements for all periods presented. The assets and liabilities of the Fincos are presented as held for sale as of September 30, 2017, and the assets and liabilities of the European Business are presented as held for sale as of December 31, 2016 in our condensed consolidated financial statements. Unless otherwise indicated, information in these notes to the condensed consolidated financial statements relates to our continuing operations. Refer to Note 2 for additional details regarding the disposal of the Opel/Vauxhall Business and the planned disposals of the Fincos. 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 2016 Form 10-K. Except for per share amounts or as otherwise specified, dollar amounts presented within tables are stated in millions. In May 2014 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), which requires us to recognize revenue when a customer obtains control rather than when we have transferred substantially all risks and rewards of a good or service and requires expanded disclosures. ASU 2014-09, as amended, is effective for us beginning January 1, 2018. ASU 2014-09 will affect the amount and timing of certain revenue related transactions primarily resulting from the earlier recognition of certain sales incentives and fixed fee license arrangements. Upon adoption of ASU 2014-09 sales incentives will be recorded at the time of sale rather than at the later of sale or announcement and fixed fee license arrangements will be recognized when the customer is granted access to intellectual property instead of over the contract period. Certain transactions with daily rental car companies may also qualify to be accounted for as a sale as opposed to the current accounting as an operating lease. We expect to adopt the provisions of ASU 2014-09 on a modified retrospective basis through a cumulative adjustment to equity. Upon adoption of ASU 2014-09 we estimate a reduction to Equity of up to $1.0 billion. This estimate is subject to change as a result of future changes in market conditions, incentive program offerings, and dealer inventory levels. We continue to assess the overall impact the adoption of ASU 2014-09 will have on our consolidated financial statements and are continuing to test and refine our processes designed to comply with ASU 2014-09 to permit adoption by January 1, 2018. In January 2016 the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (ASU 2016-01), which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in net income and which updates certain presentation and disclosure requirements. ASU 2016-01 is effective for us beginning January 1, 2018 and requires a cumulative-effect adjustment for certain items upon adoption. At September 30, 2017 the carrying value of equity investments that are not accounted for under the equity method of accounting totaled approximately $500 million and unrealized gains or losses were insignificant. We do not believe the adoption of ASU 2016-01 will be material to our consolidated financial statements. In March 2017 the FASB issued ASU 2017-07, "Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" (ASU 2017-07), which requires that the service cost component of net periodic pension and other postretirement benefits (OPEB) (income) expense be presented in the same income statement line item as other employee compensation costs, while the remaining components of net periodic pension and OPEB (income) expense are to be presented outside operating income. ASU 2017-07 is effective for us on a retrospective basis beginning January 1, 2018 and will result in the reclassification of non-service cost components from primarily Automotive cost of sales to Interest income and other non-operating income, net. We expect a resulting decrease to Operating income and an increase to Interest income and other non-operating income, net of approximately $1.3 billion for the year ended December 31, 2016. In August 2017 the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities" (ASU 2017-12), which simplifies the application of hedge accounting and more closely aligns hedge accounting with companies' risk management strategies thereby making more hedging strategies eligible for hedge accounting. Unlike current guidance, ASU 2017-12 permits hedge accounting for specific risks in hedging relationships involving nonfinancial risk and interest rate risk. ASU 2017-12 is effective for us beginning January 1, 2019, with early adoption permitted. ASU 2017-12 requires a cumulative-effect adjustment for certain items upon adoption. We are currently evaluating the impact the adoption of ASU 2017-12 will have on our consolidated financial statements. The simplifications to the application of hedge accounting may result in the future expansion of our use of hedge accounting.

Discontinued Operations and Disposal Groups [Abstract]

Discontinued Operations

On March 5, 2017 we entered into a Master Agreement (the Agreement) to sell our European Business to PSA Group for net consideration with an estimated value of approximately $2.5 billion. On July 31, 2017 we closed the sale of our Opel/Vauxhall Business to PSA Group. The transfer of the Fincos is expected to close by the end of the year subject to the receipt of the necessary regulatory approvals and satisfaction of other closing conditions.

The net consideration paid at closing for the Opel/Vauxhall Business was $1.4 billion, consisting of (1) $1.1 billion in cash; and (2) $808 million in warrants in PSA Group; partially offset by (3) the $478 million de-risking premium payment made to PSA Group for assuming certain underfunded pension liabilities. The warrants are not exercisable for five years and do not include any governance or voting rights with respect to PSA Group. In addition, we agreed to sell the shares of PSA Group received upon exercise of the warrants within 35 days after exercise. The net consideration to be paid for the Fincos will be 0.8 times their book value at closing, which we estimate will be approximately $1.1 billion based on exchange rates at September 30, 2017, subject to foreign currency fluctuations. The purchase price is subject to certain working capital adjustments as provided in the Agreement.

The total charge from the sale of the European Business is expected to be approximately $6.3 billion, net of tax. During the three months ended September 30, 2017 the Company recorded a charge of $5.4 billion, of which $3.1 billion is recorded in Income (loss) from discontinued operations, net of tax and $2.3 billion is recorded in Income tax expense, as a result of the sale of the Opel/Vauxhall Business. The charge relates to: (1) $4.3 billion of deferred tax assets that will no longer be realizable or that transferred to PSA Group; (2) $1.5 billion related to previously deferred pension losses and payment of the de-risking premium to PSA Group for its assumption of certain underfunded pension liabilities; and (3) other net charges primarily related to contract cancellations, working capital adjustments and certain transitional services and other costs to support the separation of operations to be provided for a period of time following closing; partially offset by proceeds. During the three months ended June 30, 2017 we recognized, on a pre-tax basis, a charge of $836 million in Income (loss) from discontinued operations consisting of (1) a charge of $421 million for the cancellation of production programs resulting from the convergence of vehicle platforms between the European Business and PSA Group; (2) a disposal loss of $324 million as a result of the Fincos being classified as held for sale; and (3) other insignificant charges. We expect to record a disposal loss of approximately $300 million upon sale of the Fincos.

Our wholly-owned subsidiary (the Seller) has 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 emissions and product liabilities. The Company has entered into a guarantee for the benefit of PSA Group and pursuant to which the Company has agreed to guarantee the Seller's obligation to indemnify PSA Group for certain losses resulting from any inaccuracy of certain representations and warranties or breaches of our covenants in the Agreement and for certain other liabilities. Certain of these indemnification obligations are subject to time limitations, thresholds and/or caps as to the amount of required payments.

We retained net underfunded pension liabilities of $6.8 billion owed primarily to current pensioners and former employees of the European Business with vested pension rights. PSA Group assumed approximately $3.1 billion of net underfunded pension liabilities primarily with respect to active employees of the Opel/Vauxhall Business, and during the three months ended September 30, 2017 the Seller made payments to PSA Group, or one or more pension funding vehicles, of $3.4 billion in respect of these assumed liabilities, which includes pension funding payments for active employees and the de-risking premium payment of $478 million discussed above. At closing we drew upon our three-year unsecured revolving credit facility to fund these payments. We issued debt securities, as described in Note 9, thereafter to repay the amount drawn on our credit facility.

As part of the retained pension liabilities described above, we retained the United Kingdom defined benefit pension plans in existence at signing related to the Opel/Vauxhall Business, including responsibility for service cost accruals through the closing date. Those plans with active participants closed to future accrual as of July 30, 2017. Any future service cost accruals on and from the closing date will be the responsibility of PSA Group.

We have agreed to purchase from and supply to PSA Group certain vehicles for a period of time following closing. During the three and nine months ended September 30, 2017 Total net sales and revenue from continuing operations include $362 million and purchases and expenses incurred by our continuing operations were insignificant related to transactions with the Opel/Vauxhall Business that would have been eliminated in consolidation prior to the sale of the Opel/Vauxhall Business. During the nine months ended September 30, 2017 cash payments were insignificant and cash receipts of $558 million were recorded in Net cash provided by operating cash flows - continuing operations related to transactions with the Opel/Vauxhall Business.

The following table summarizes the results of the discontinued operations:

Fair value of GM Financial receivables							$	40,513								$	33,181

We estimate the fair value of retail finance receivables using observable and unobservable Level 3 inputs within a cash flow model. The inputs reflect assumptions regarding expected prepayments, deferrals, delinquencies, recoveries and charge-offs of the loans within the portfolio. The cash flow model produces an estimated amortization schedule of the finance receivables. The projected cash flows are then discounted to derive the fair value of the portfolio. Macroeconomic factors could affect the credit performance of the portfolio and therefore could potentially affect the assumptions used in our cash flow model. A substantial majority of our commercial finance receivables have variable interest rates. The carrying amount, a Level 2 input, is considered to be a reasonable estimate of fair value.

The allowance for loan losses on retail and commercial finance receivables included a collective allowance of $617 million and $525 million and a specific allowance of $331 million and $280 million at September 30, 2017 and December 31, 2016.

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 scores 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. In North America, while we historically focused on consumers with lower than prime credit scores, we have expanded our prime lending programs. At September 30, 2017 and December 31, 2016, 39% and 48% of the retail finance receivables in North America were from consumers with sub-prime credit scores, which are defined as FICO scores 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 such payment was contractually due. At September 30, 2017 and December 31, 2016 the accrual of finance charge income had been suspended on delinquent retail finance receivables with contractual amounts due of $797 million and $798 million. 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:



	September 30, 2017				September 30, 2016
	Amount		Percent of Contractual Amount Due		Amount		Percent of Contractual Amount Due
31-to-60 days delinquent	$	1,176	3.6	%	$	1,112	4.4	%

Total finance receivables more than 30 days delinquent or in repossession	$	1,752	5.4	%	$	1,660	6.5	%

At September 30, 2017 and December 31, 2016 retail finance receivables classified as troubled debt restructurings and individually evaluated for impairment were $2.2 billion and $1.9 billion and the allowance for loan losses included $328 million and $276 million of specific allowances on these receivables.

Commercial Finance Receivables Our commercial finance receivables consist of dealer financings, primarily for inventory purchases. A proprietary model is 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. At September 30, 2017 and December 31, 2016 the commercial finance receivables on non-accrual status were insignificant. The following table summarizes the credit risk profile by dealer risk rating of commercial finance receivables:

Variable Interest Entities [Abstract]

Variable Interest Entities

GM Financial uses special purpose entities (SPEs) that are considered variable interest entities (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:



	September 30, 2017		December 31, 2016
Restricted cash – current	$	1,768	$	1,302
Restricted cash – non-current	$	523	$	478

GM Financial short-term debt and current portion of long-term debt	$	19,207	$	17,526
GM Financial long-term debt	$	20,981	$	16,659

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.

Automotive and GM Financial Debt



	September 30, 2017				December 31, 2016
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Total automotive debt	$	13,635	$	14,798	$	10,560	$	11,399
Fair value utilizing Level 1 inputs			$	12,877			$	9,515
Fair value utilizing Level 2 inputs			$	1,921			$	1,884

The fair value of automotive debt measured utilizing Level 1 inputs was based on quoted prices in active markets for identical instruments that a market participant can access at the measurement date. The fair value of automotive debt measured utilizing Level 2 inputs was based on a discounted cash flow model using observable inputs. This model utilizes observable inputs such as contractual repayment terms and benchmark yield curves, plus a spread based on our senior unsecured notes that is intended to represent our nonperformance risk. We obtain the benchmark yield curves and yields on unsecured notes from independent sources that are widely used in the financial industry. At September 30, 2017 and December 31, 2016 the fair value of automotive debt exceeded its carrying amount due primarily to a decrease in bond yields compared to yields at the time of issuance.

In August 2017 we issued $3.0 billion in aggregate principal amount of senior unsecured notes with an initial weighted average interest rate of 4.5% and maturity dates ranging from 2020 to 2048. The indentures governing these notes contain terms and covenants customary of these types of securities including limitation on the amount of certain secured debt we may incur. The net proceeds from the issuance of these senior unsecured notes were used to repay the $3.0 billion drawn on our three-year unsecured revolving credit facility in the three months ended September 30, 2017 to fund the payments to PSA Group, or one or more pension funding vehicles, for the assumed net underfunded pension liabilities in connection with the sale of the Opel/Vauxhall Business as described in Note 2.



	September 30, 2017				December 31, 2016
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Secured debt	$	40,775	$	40,889	$	35,087	$	35,162
Unsecured debt	38,263		39,411		29,476		30,045
Total GM Financial debt	$	79,038	$	80,300	$	64,563	$	65,207

Fair value utilizing Level 2 inputs			$	78,293			$	62,951
Fair value utilizing Level 3 inputs			$	2,007			$	2,256

The fair value of GM Financial debt measured utilizing Level 2 inputs was based on quoted market prices for identical instruments and if unavailable, quoted market prices of similar instruments. For debt with original maturity or revolving period of eighteen months or less par value is considered to be a reasonable estimate of fair value. The fair value of GM Financial debt measured utilizing Level 3 inputs was based on the discounted future net cash flows expected to be settled using current risk-adjusted rates.

Secured debt consists of revolving credit facilities and securitization notes payable. Most of the secured debt was issued by VIEs and is repayable only from proceeds related to the underlying pledged Securitized Assets. Refer to Note 8 for additional information on GM Financial's involvement with VIEs. In the nine months ended September 30, 2017 we entered into new or renewed credit facilities with a total net additional borrowing capacity of $1.7 billion, which had substantially the same terms as existing debt and we issued $18.8 billion in aggregate principal amount of securitization notes payable with an initial weighted average interest rate of 2.09% and maturity dates ranging from 2019 to 2025.

Unsecured debt consists of senior notes, credit facilities and other unsecured debt. In the nine months ended September 30, 2017 we issued $10.6 billion in aggregate principal amount of senior notes with an initial weighted average interest rate of 2.87% and maturity dates ranging from 2019 to 2027.

Each of the revolving credit facilities and the indentures governing GM Financial's notes contain terms and covenants including limitations on GM Financial's ability to incur certain liens.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation-Related Liability and Tax Administrative Matters In the normal course of business, we are named from time to time as a defendant in various legal actions, including arbitrations, class actions and other litigation, that arise in connection with our business as a global company. We identify below the material individual proceedings and investigations in connection with which 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 September 30, 2017 and December 31, 2016 total accruals of $1.1 billion and $1.2 billion were recorded in Accrued liabilities and Other liabilities. In many proceedings, it is inherently difficult to determine whether any loss is probable or even reasonably possible or to estimate the size or range of the possible loss. Accordingly an adverse outcome 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. Through October 17, 2017 we were aware of over 100 putative class actions pending against GM in various courts in the U.S. and Canada alleging that consumers who purchased or leased vehicles manufactured by GM or General Motors Corporation had been economically harmed by one or more of the recalls announced in 2014 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. There is also a civil action brought by the Arizona Attorney General relating to the recalls that seeks civil penalties and injunctive relief for alleged violations of state laws. We also were 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 recalls announced in 2014 (personal injury cases). In general, these personal injury cases seek recovery for purported compensatory damages, punitive damages and other relief. Since 2016, several bellwether trials have taken place in the personal injury cases in the U.S. District Court for the Southern District of New York (Southern District), which is administering a federal multi-district litigation, and in a Texas state court, which is administering a Texas state multi-district litigation (MDL). None of these trials resulted in a finding of liability against GM. An additional personal injury bellwether trial is scheduled in 2018 along with non-bellwether trials in various courts. On July 15, 2016 the Southern District granted in part and denied in part GM's motion to dismiss plaintiffs' complaint in the federal multi-district litigation seeking damages for alleged economic loss relating to the ignition switch and other recalls by GM in 2014. Among other things, the Southern District dismissed plaintiffs' claims brought under the Racketeer Influenced and Corrupt Organization Act (RICO) and rejected plaintiffs' broadest theory of damages – that plaintiffs could seek recovery for alleged reduction in the value of their vehicles due to damage to GM's reputation and brand as a result of the ignition switch matter. The Southern District granted GM's motion to dismiss with respect to certain state law claims but denied it as to other state law claims. On September 15, 2016, plaintiffs filed a Fourth Amended Consolidated Complaint amending their economic-loss claims, and GM moved to dismiss certain claims in that Complaint as well. On June 30, 2017, the Southern District issued an order granting in part and denying in part GM’s motion. In its order, among other things, the Southern District reaffirmed its dismissal of plaintiffs’ brand devaluation claim and theory of damages and dismissed the claims of any plaintiff who purchased a vehicle before GM came into existence in July 2009. With respect to plaintiffs’ claims under the laws of certain states that were at issue in the motion, the Court granted GM’s motion to dismiss with respect to certain state law claims but denied it as to other state law claims. In April 2015 the United States Bankruptcy Court for the Southern District of New York (Bankruptcy Court) issued a decision precluding claims against us based upon pre-sale accidents, claims based upon the acts or conduct by General Motors Corporation and claims asserting successor liability for obligations owed by General Motors Corporation (successor liability claims), except for claims asserting liabilities that had been expressly assumed by us in the July 2009 Sale Agreement, and claims that could be asserted against us only if they were otherwise viable and arose solely out of our own independent post-closing acts and did not in any way rely on acts or conduct by General Motors Corporation. On July 13, 2016 the United States Court of Appeals for the Second Circuit (Second Circuit) issued a decision and judgment affirming in part, reversing in part, and vacating portions of the Bankruptcy Court's decision and subsequent judgment. Among other things, the Second Circuit held that the 2009 Sale Order could not be enforced to bar claims against GM asserted by either plaintiffs who purchased used vehicles after the sale closing or against purchasers who asserted claims relating to the ignition switch defect, including pre-closing personal injury claims and economic-loss claims. The Second Circuit also vacated that portion of the Bankruptcy Court judgment enforcing the 2009 Sale Order against plaintiffs with pre-sale claims based on defects other than the ignition switch and remanded that issue to the Bankruptcy Court for further proceedings. In April 2017, the United States Supreme Court denied our petition for certiorari. Certain of these pre-sale claims were resolved through GM's Ignition Switch Recall Compensation Program (Compensation Program) and should not be the subject of additional litigation. For Plaintiffs asserting pre-sale claims related to the ignition switch defect that were not resolved by the Compensation Program, those Plaintiffs must still establish their right to assert successor liability claims and demonstrate that their claims have merit. In August 2017, the MDL court 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 the putative shareholder class action filed in the United States District Court for the Eastern District of Michigan (Eastern District) on behalf of purchasers of our common stock from November 17, 2010 to July 24, 2014 (Shareholder Class Action), the lead plaintiff, the New York State Teachers' Retirement System, alleged that GM and several current and former officers and employees made material misstatements and omissions relating to problems with the ignition switch and other matters in SEC filings and other public statements. On May 23, 2016 the Eastern District entered a judgment approving a class-wide settlement of the Shareholder Class Action for $300 million. One shareholder has filed an appeal of the decision approving the settlement. Three shareholder derivative actions against certain current and former GM directors and officers are pending in the Eastern District. In two of those matters that have been consolidated, the Court issued an Order on August 4, 2017 denying our motion to dismiss without prejudice and granting leave for Plaintiff to file an amended complaint. The court is still considering a motion to dismiss in the other action. Two derivative actions filed in the Circuit Court of Wayne County, Michigan, which have been consolidated, are stayed pending disposition of the federal derivative actions. 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, including the United States Attorney’s Office for the Southern District of New York (the U.S. Attorney's Office). Ongoing matters or investigations as of September 30, 2017, included litigation initiated by the Arizona Attorney General, litigation initiated by the Orange County District Attorney, and investigations by 49 state attorneys general, and an inquiry from the U.S. General Services Administration which has subsequently been closed in light of our obligations under the Deferred Prosecution Agreement (DPA). Investigations into consumer protection claims by 49 state attorneys general and the litigation initiated by the Orange County District Attorney have been resolved. We believe we are cooperating fully with all reasonable pending requests for information. Such matters could in the future result in the imposition of damages, fines, civil consent orders, civil and criminal penalties or other remedies. With regard to the investigation by the U.S. Attorney's Office, on September 16, 2015, we entered into the DPA with the U.S. Attorney's Office regarding its investigation of the events leading up to certain recalls regarding faulty ignition switches. Pursuant to the DPA we have paid the United States $900 million as a financial penalty, and we agreed to retain an independent monitor to review and assess our policies, practices or procedures related to statements about motor vehicle safety, the provision of information to those responsible for recall decisions, recall processes and addressing known defects in certified pre-owned vehicles. In addition, the U.S. Attorney's Office agreed to recommend to the Southern District that prosecution of GM on a two-count information filed in the Southern District be deferred for three years. The U.S. Attorney's Office also agreed that if we are in compliance with all of our obligations under the DPA, the U.S. Attorney's Office will, within 30 days after the expiration of the period of deferral (including any extensions thereto), seek dismissal with prejudice of the two-count information filed against GM. For a further description of the terms and conditions of the DPA refer to Note 15 of our 2016 Form 10-K. The total amount accrued for ignition switch and the various other related recalls at September 30, 2017 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. 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 believe it is probable that we will incur additional liabilities beyond what has already been accrued for at least a portion of the remaining matters, whether through settlement or judgment; however, we are currently unable to estimate an overall amount or range of loss because these matters involve significant uncertainties, including the legal theory or the nature of the investigations, claims and/or lawsuits, the complexity of the facts, the lack of documentation available to us with respect to particular cases or groups of cases, the results of any investigation or litigation and the timing of resolution of the investigation or litigations, including any appeals, further proceedings regarding interpretation and application of the Second Circuit's July 13, 2016 decision and certain common law doctrines, and further proceedings following the Southern District's July 15, 2016 decision and its June 30, 2017 decision on GM's motion to dismiss the Fourth Amended and Consolidated Complaint. 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 Commencing on or about September 29, 2010 current and former hourly employees of GM Korea Company (GM Korea) filed eight separate group actions in the Incheon District Court in Incheon, Korea. The cases, which in 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 the Presidential Decree of the Korean Labor Standards Act. On November 23, 2012 the Seoul High Court (an intermediate level appellate court) affirmed a decision of the Incheon District Court in a case 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). On May 29, 2014 the Supreme Court 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. On reconsideration, the Seoul High Court held in GM Korea’s favor on October 30, 2015, after which the plaintiffs appealed to the Supreme Court. In July 2014 GM Korea and its labor union also agreed to include bonuses and certain allowances in Ordinary Wages retroactive to March 1, 2014. Therefore our accrual related to these cases was reclassified from a contingent liability to the Pensions liability. We estimate our reasonably possible loss in excess of amounts accrued to be approximately $547 million at September 30, 2017, which relates to periods before March 1, 2014. We are also party to litigation with current and former salaried employees over allegations relating to Ordinary Wages regulation. On November 26 and 27, 2015 the Supreme Court remanded two salary cases to the Seoul High Court for a review of the merits. On September 1, 2017, the Seoul High Court issued a ruling concerning those two salary cases and another salaried worker case. Among other things, the Seoul High Court held that there was no agreement between GM Korea and its salaried workers regarding whether to include fixed bonuses in the calculation of Ordinary Wages. As a result, the workers are not barred from filing retroactive wage claims. On September 13, 2017, GM Korea appealed this ruling to the Supreme Court. At September 30, 2017 the reasonably possible loss for salary cases in excess of amounts accrued was approximately $169 million. 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. These cases are currently pending before various courts in Korea. GM Brazil Indirect Tax Claim In March 2017 the Supreme Court of Brazil issued a decision concluding that a certain state value added tax should not be included in the calculation of federal gross receipts taxes. The decision reduces GM Brazil’s gross receipts tax prospectively and, potentially, retrospectively. The retrospective right to recover is under judicial review and we do not expect resolution during 2017. If the Supreme Court of Brazil grants retrospective recovery we estimate potential recoveries of up to $1.5 billion. However, given the remaining uncertainty regarding the ultimate judicial resolution of this matter we are unable to assess the likelihood of any favorable outcome at this time. We have not recorded any amounts relating to the retrospective nature of this matter. Other Litigation-Related Liability and Tax Administrative Matters Various other legal 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, including CO₂ and nitrogen oxide, fuel economy, and related government regulations; product warranties; financial services; dealer, supplier and other contractual relationships; government regulations relating to payments to foreign companies; government regulations relating to competition issues; tax-related matters not subject to the provision of Accounting Standards Codification (ASC) 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. There are several putative class actions pending against GM in federal courts in the U.S. and in the Provincial Courts in Canada alleging that various vehicles sold including model year 2011-2016 Duramax Diesel Chevrolet Silverado and GMC Sierra vehicles, violate federal and state emission standards. GM also faces a series of additional lawsuits based primarily on allegations in the Duramax suit, including putative shareholder class actions claiming violations of federal securities law. 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. 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 South American 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 $600 million at September 30, 2017. 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 September 30, 2017. 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 $1.0 billion at September 30, 2017. Takata Matters On May 4, 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 phase-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. On May 16, 2016 Takata issued its first DIR in connection with the amended consent order, and on January 3, 2017, Takata issued its second set of DIRs. Although we do not believe there is a safety defect at this time in any unrecalled GM vehicles within the scope of the Takata DIRs, in cooperation with NHTSA we filed Preliminary DIRs on May 27, 2016, updated as of June 13, 2016, covering 2.5 million of certain of our GMT900 vehicles, which are full-size pick-up trucks and sport utility vehicles (SUVs). On November 15, 2016 we filed a petition for inconsequentiality and request for deferral of determination regarding those GMT900 vehicles. On November 28, 2016 NHTSA granted GM's deferral request in connection with this petition. The deferral provided GM until August 31, 2017 to present evidence and analysis that our vehicles do not pose an unreasonable risk to motor vehicle safety. Takata filed a second set of equipment DIRs on January 3, 2017 and we filed a second set of Preliminary DIRs for certain GMT900 vehicles on January 10, 2017. These January 2017 DIRs are consistent with GM’s May 2016 DIRs. On the same day, we also filed a second petition for inconsequentiality and deferral of decision with respect to the vehicles subject to our January 2017 DIRs. On January 18, 2017, NHTSA consolidated our first and second petitions for inconsequentiality and will rule on both at the same time. On August 25, 2017, we filed a supplemental brief in support of our petitions that provided NHTSA with the results of our long-term study and testing and 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. In our brief, we requested that NHTSA grant our petitions or, in the alternative, grant an additional deferral period to provide time for further testing. We believe these vehicles are currently performing as designed and ongoing testing continues to 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 $1.0 billion. GM is engaged in discussions with regulators outside the U.S. with respect to Takata inflators. There are 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. We were required to recall certain vehicles outside of the U.S. in the three months ended September 30, 2017 to replace Takata inflators in these vehicles. Additional recalls, if any, could be material to our results of operations and cash flows. We continue to monitor the international situation. Through October 17, 2017 we were aware of two putative class actions pending against GM in federal court in the U.S., one putative class action in Mexico and four 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. On August 16, 2017, the bankruptcy court hearing the Takata bankruptcy entered an order staying all Takata related litigation against automotive manufacturers, including GM, until November 16, 2017. Product Liability With respect to product liability claims (other than claims relating to the ignition switch recalls discussed above) involving GM and General Motors Corporation products, we believe that any judgment against us for actual damages will be adequately covered by our recorded accruals and, where applicable, excess liability insurance coverage. In addition we indemnify dealers for certain product liability related claims, including claims related to products sold by General Motors Corporation's dealers. At September 30, 2017 and December 31, 2016 liabilities of $615 million and $656 million were recorded in Accrued liabilities and Other liabilities 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. In light of vehicle recalls in recent years 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. Guarantees We enter into indemnification agreements for liability claims involving products manufactured primarily by certain joint ventures. We also provide vehicle repurchase guarantees and payment guarantees on commercial loans outstanding with third parties such as dealers. These guarantees terminate in years ranging from 2017 to 2032 or upon the occurrence of specific events or are ongoing. We believe that the related potential costs incurred are adequately covered and our recorded accruals are insignificant. The maximum liability, calculated as future undiscounted payments, was $5.2 billion and $4.3 billion for these guarantees at September 30, 2017 and December 31, 2016, the majority of which relate to the indemnification agreements. In some instances certain assets of the party whose debt or performance we have guaranteed may offset, to some degree, the amount of certain guarantees. Our payables to the party whose debt or performance we have guaranteed may also reduce the amount of certain guarantees. If vehicles are required to be repurchased under vehicle repurchase obligations, the total exposure would be reduced to the extent vehicles are able to be resold to another dealer. 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.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2017
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 2007 to 2016 with various significant tax jurisdictions. In the three months ended September 30, 2017 Income tax expense of $2.3 billion primarily resulted from tax expense attributable to entities included in our effective tax rate calculation of $583 million including tax benefits from foreign dividends and $2.3 billion related to the establishment of a valuation allowance on deferred tax assets that will no longer be realizable as a result of the sale of the Opel/Vauxhall Business as described in Note 2, partially offset by tax benefits related to tax settlements. In the three months ended September 30, 2016 Income tax expense of $902 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation of $1.3 billion, partially offset by tax benefits related to foreign currency losses. In the nine months ended September 30, 2017 Income tax expense of $3.6 billion primarily resulted from tax expense attributable to entities included in our effective tax rate calculation of $2.1 billion including tax benefits from foreign dividends and $2.3 billion related to the establishment of a valuation allowance on deferred tax assets that will no longer be realizable as a result of the sale of the Opel/Vauxhall Business as described in Note 2, partially offset by tax benefits related to tax settlements. In the nine months ended September 30, 2016 Income tax expense of $2.4 billion primarily resulted from tax expense attributable to entities included in our effective tax rate calculation of $3.4 billion, partially offset by tax benefits related to foreign currency losses, tax settlements and deductions taken for stock investments in non-U.S. affiliates. At September 30, 2017 we had $30.1 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. The net operating losses and income tax credits include U.S. operating loss and tax credit carryforward deferred tax assets of $9.6 billion that expire by 2037 if not utilized; and Non-U.S. operating loss and tax credit carryforward deferred tax assets of $4.9 billion of which $946 million expire by 2037 if not utilized and $4.0 billion can be carried forward indefinitely.

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 other costs to improve the utilization of remaining facilities. To the extent these programs involve voluntary separations, no liabilities are generally recorded until offers to employees are accepted. If employees are involuntarily terminated, a liability is generally recorded at the communication date. Related charges are recorded in Automotive cost of sales and Automotive 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:

In the nine months ended September 30, 2017, restructuring and other initiatives primarily include restructuring actions announced in the three months ended June 30, 2017 in GMIO. These actions related primarily to the withdrawal of Chevrolet from the Indian and South African markets by the end of 2017 and the transition of our South Africa manufacturing operations to Isuzu Motors. We intend to continue manufacturing vehicles in India for sale to certain export markets. We recorded charges of $460 million in GMIO primarily consisting of $297 million of asset impairments, sales incentives, inventory provisions and other charges, not reflected in the table above, and $163 million of dealer restructurings, employee separations and other contract cancellation costs, which are reflected in the table above and insignificant costs for separation and other programs in GMNA and GMSA. We expect to complete these programs in 2017.

Other GMIO restructuring programs reflected in the table above include separation and other programs in Australia, Korea and India and the withdrawal of the Chevrolet brand from Europe. Collectively these programs had a total cost since inception in 2013 of $883 million. We expect to complete these programs in 2017 and incur insignificant additional restructuring and other charges.

In the nine months ended September 30, 2016 restructuring and other initiatives related primarily to charges of $240 million in the three months ended March 31, 2016 in GMNA related to the cash severance incentive program to qualified U.S. hourly employees under our 2015 labor agreement with the International Union, United Automobile, Aerospace and Agriculture Implement Workers of America (UAW) and insignificant costs for separation and other programs in Australia, Korea and India and the withdrawal of the Chevrolet brand from Europe.

Stockholders' Equity

Stockholders' Equity and Noncontrolling Interests

At September 30, 2017 and December 31, 2016 we had 2.0 billion shares of preferred stock and 5.0 billion shares of common stock authorized for issuance. At September 30, 2017 and December 31, 2016 we had 1.4 billion and 1.5 billion shares of common stock issued and outstanding. In the nine months ended September 30, 2017 and 2016 we purchased 86 million and 48 million shares of our outstanding common stock for $3.0 billion and $1.5 billion as part of the common stock repurchase program announced in March 2015, which our Board of Directors increased and extended in January 2016 and January 2017. Our total dividends paid on common stock were $546 million and $585 million in the three months ended September 30, 2017 and 2016 and $1.7 billion and $1.8 billion in the nine months ended September 30, 2017 and 2016.

In September 2017 GM Financial issued $1.0 billion of Fixed-to-Floating Rate Cumulative Perpetual Preferred Stock, Series A, $0.01 par value, with a liquidation preference of $1,000 per share. The preferred stock is classified as noncontrolling interests on our condensed consolidated financial statements. Dividends will be paid semi-annually when declared starting March 30, 2018 at a fixed rate of 5.75% or approximately $58 million annually for the first 10 years after issuance, after which, if not called, dividends will be paid based on a floating rate.

Acquisition of Business	9 Months Ended
Acquisition of Business	Sep. 30, 2017
Business Combinations [Abstract]
Acquisition of Business	Acquisition of Business On May 12, 2016 we acquired all of the outstanding capital stock of Cruise Automation Inc., an autonomous vehicle technology company, to further accelerate our development of autonomous vehicles. The deal consideration at closing was $581 million, of which $291 million was paid in cash and approximately $290 million was paid through the issuance of new common stock. The fair value of the common stock issued was determined based on the closing price of our common stock on May 12, 2016. In conjunction with the acquisition, we entered into other agreements that will result in future costs contingent upon the continued employment of key individuals and additional performance-based awards contingent upon the achievement of specific technology and commercialization milestones. Of the total consideration, $130 million was allocated to intangible assets, primarily in-process research and development with an indefinite life until fully developed and commercialized, $39 million was allocated to deferred tax liabilities, net of other assets, and $490 million was allocated to non-tax-deductible goodwill in Corporate primarily related to the synergies expected to arise as a result of the acquisition.

Segment Reporting [Abstract]

Segment Reporting

We analyze the results of our business through the following segments: GMNA, GMIO, GMSA and GM Financial. As discussed in Note 2, the European Business is presented as discontinued operations and is excluded from our segment results for all periods presented. The European Business was previously reported as our GM Europe (GME) segment and part of GM Financial. The chief operating decision maker evaluates the operating results and performance of our automotive segments through earnings before interest and income taxes-adjusted, which is presented net of noncontrolling interests. The chief operating decision maker evaluates GM Financial through earnings before income taxes-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. Our automotive manufacturing operations are integrated within the segments, benefit from broad-based trade agreements and are subject to regulatory requirements. 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 cars, trucks, crossovers 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, cars, trucks and crossovers 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 primarily meets the demands of customers in North America with vehicles developed, manufactured and/or marketed under the Buick, Cadillac, Chevrolet and GMC brands. The demands of customers outside North America are primarily met with vehicles developed, manufactured and/or marketed under the Buick, Cadillac, Chevrolet, GMC, and Holden brands. We also have equity ownership stakes directly or indirectly in entities through various regional subsidiaries, primarily in Asia. These companies design, manufacture and/or market vehicles under the Baojun, Buick, Cadillac, Chevrolet, Jiefang and Wuling brands.

Our automotive operations' interest income and interest expense, Maven, legacy costs from the Opel/Vauxhall Business (primarily pension costs), corporate expenditures including autonomous vehicle-related engineering and other costs 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, goodwill, intangibles, 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.

Beginning in the three months ended December 31, 2017, we intend to change our reportable segments as a result of planned changes in our organizational structure and the evolution of our business resulting from the sale of the Opel/Vauxhall Business and the various strategic actions taken in the GMIO region. As a result, our GMSA and GMIO segments will be reported as one, combined reportable international segment, GM International (GMI). Our GMNA and GM Financial segments will not be impacted.

The following tables summarize key financial information by segment:

Nature of Operations and Basis of Presentation (Policies)	9 Months Ended
	Sep. 30, 2017
Nature of Operations and Basis of Presentation [Abstract]
Basis of Accounting	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 2016 Form 10-K. Except for per share amounts or as otherwise specified, dollar amounts presented within tables are stated in millions.
Accounting Standards	In May 2014 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), which requires us to recognize revenue when a customer obtains control rather than when we have transferred substantially all risks and rewards of a good or service and requires expanded disclosures. ASU 2014-09, as amended, is effective for us beginning January 1, 2018. ASU 2014-09 will affect the amount and timing of certain revenue related transactions primarily resulting from the earlier recognition of certain sales incentives and fixed fee license arrangements. Upon adoption of ASU 2014-09 sales incentives will be recorded at the time of sale rather than at the later of sale or announcement and fixed fee license arrangements will be recognized when the customer is granted access to intellectual property instead of over the contract period. Certain transactions with daily rental car companies may also qualify to be accounted for as a sale as opposed to the current accounting as an operating lease. We expect to adopt the provisions of ASU 2014-09 on a modified retrospective basis through a cumulative adjustment to equity. Upon adoption of ASU 2014-09 we estimate a reduction to Equity of up to $1.0 billion. This estimate is subject to change as a result of future changes in market conditions, incentive program offerings, and dealer inventory levels. We continue to assess the overall impact the adoption of ASU 2014-09 will have on our consolidated financial statements and are continuing to test and refine our processes designed to comply with ASU 2014-09 to permit adoption by January 1, 2018. In January 2016 the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (ASU 2016-01), which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in net income and which updates certain presentation and disclosure requirements. ASU 2016-01 is effective for us beginning January 1, 2018 and requires a cumulative-effect adjustment for certain items upon adoption. At September 30, 2017 the carrying value of equity investments that are not accounted for under the equity method of accounting totaled approximately $500 million and unrealized gains or losses were insignificant. We do not believe the adoption of ASU 2016-01 will be material to our consolidated financial statements. In March 2017 the FASB issued ASU 2017-07, "Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" (ASU 2017-07), which requires that the service cost component of net periodic pension and other postretirement benefits (OPEB) (income) expense be presented in the same income statement line item as other employee compensation costs, while the remaining components of net periodic pension and OPEB (income) expense are to be presented outside operating income. ASU 2017-07 is effective for us on a retrospective basis beginning January 1, 2018 and will result in the reclassification of non-service cost components from primarily Automotive cost of sales to Interest income and other non-operating income, net. We expect a resulting decrease to Operating income and an increase to Interest income and other non-operating income, net of approximately $1.3 billion for the year ended December 31, 2016. In August 2017 the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities" (ASU 2017-12), which simplifies the application of hedge accounting and more closely aligns hedge accounting with companies' risk management strategies thereby making more hedging strategies eligible for hedge accounting. Unlike current guidance, ASU 2017-12 permits hedge accounting for specific risks in hedging relationships involving nonfinancial risk and interest rate risk. ASU 2017-12 is effective for us beginning January 1, 2019, with early adoption permitted. ASU 2017-12 requires a cumulative-effect adjustment for certain items upon adoption. We are currently evaluating the impact the adoption of ASU 2017-12 will have on our consolidated financial statements. The simplifications to the application of hedge accounting may result in the future expansion of our use of hedge accounting.
