Accounting Policies [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 2017 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 June 30, 2018 we changed the presentation of our condensed consolidated statements of cash flows to separately classify Depreciation and impairment of Equipment on operating leases, net and Depreciation, amortization and impairment charges on Property, net. We have made corresponding reclassifications to the comparable information for all periods presented.
Principles of Consolidation | Principles of Consolidation The Principles of Consolidation supplements information presented in our 2017 Form 10-K for the adoption on January 1, 2018 of Accounting Standards Update (ASU) 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (ASU 2016-01). We consolidate entities that we control due to ownership of a majority voting interest and we consolidate variable interest entities (VIEs) when we have variable interests and are the primary beneficiary. We continually evaluate our involvement with VIEs to determine when these criteria are met. 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. Beginning January 1, 2018 we no longer use the cost method of accounting.
Recently Adopted Accounting Standards and Accounting Standards Not Yet Adopted | Recently Adopted Accounting Standards Effective January 1, 2018 we adopted ASU 2014-09, "Revenue from Contracts with Customers" as amended (ASU 2014-09), as incorporated into Accounting Standards Codification (ASC) 606, on a modified retrospective basis by recognizing a cumulative effect adjustment to the opening balance of Retained earnings. Under ASU 2014-09 sales incentives will now be recorded at the time of sale rather than at the later of sale or announcement, thereby resulting in the shifting of incentive amounts to an earlier quarter and fixed fee license arrangements will now be recognized when access to intellectual property is granted instead of over the contract period. We currently expect the retiming of quarterly incentive amounts to offset for the year ending December 31, 2018. Actual incentive spending is dependent upon future market conditions. Beginning January 1, 2018 certain transfers to daily rental companies are accounted for as sales when ownership of the vehicle is not expected to transfer back to us. Such transactions were previously accounted for as operating leases. Transfers that occurred prior to January 2018 continue to be accounted for as operating leases because at the original time of transfer an expectation existed that ownership of the vehicle would transfer back to us. The following table summarizes the financial statement line items within our condensed consolidated income statement and balance sheet significantly impacted by ASU 2014-09:

Retained earnings | $ | 20,865 |  |  | $ | 22,633 |  |  | $ | (1,768 | )
Effective January 1, 2018 we adopted ASU 2016-01, on a modified retrospective basis, with a $182 million cumulative effect adjustment recorded to the opening balance of Retained earnings to adjust an investment previously carried at cost to its fair value. ASU 2016-01 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. In the three months ended March 31, 2018 we adopted ASU 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities" (ASU 2017-12), on a modified retrospective basis and adopted ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (ASU 2018-02), on a modified retrospective basis. ASU 2018-02 provides the option to reclassify stranded tax effects related to the U.S. Tax Cuts and Jobs Act of 2017 (the Tax Act) in accumulated other comprehensive income to retained earnings. The adjustment relates to the change in the U.S. corporate income tax rate. The cumulative effect of the adjustments to the opening balance of Retained earnings for these adopted standards was $108 million. The following table summarizes the changes to our condensed consolidated balance sheet for the adoption of ASU 2014-09, ASU 2016-01, ASU 2017-12 and ASU 2018-02:
| December 31, 2017 |  | Adjustment due to ASU 2014-09 |  | Adjustment due to ASU 2016-01, ASU 2017-12 and ASU 2018-02 |  | January 1, 2018

Accumulated other comprehensive loss | $ | (8,011 | ) |  | $ | — |  |  | $ | (98 | ) |  | $ | (8,109 | )
Effective January 1, 2018 we adopted ASU 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Payments" (ASU 2016-15), which clarified guidance on the classification of certain cash receipts and payments in the statement of cash flows. The adoption of ASU 2016-15 did not have a material impact on our condensed consolidated financial statements and prior periods were not restated. Effective January 1, 2018 we adopted 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) on a retrospective basis, 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. The remaining components of net periodic pension and OPEB (income) expense are now presented outside operating income. Amounts previously reflected in Operating income were reclassified to Interest income and other non-operating income, net in accordance with the provisions of ASU 2017-07. Refer to Note 13 for amounts that were reclassified. Accounting Standards Not Yet Adopted In February 2016 the Financial Accounting Standards Board issued ASU 2016-02, "Leases" (ASU 2016-02), which requires us as the lessee to recognize most leases on the balance sheet thereby resulting in the recognition of right of use assets and lease obligations for those leases currently classified as operating leases. The accounting for leases where we are the lessor remains largely unchanged. We are continuing to assess the accounting and disclosure impact of ASU 2016-02 and refine our processes to permit adoption on January 1, 2019. We plan to elect the optional transition method as well as the package of practical expedients upon adoption. We expect the primary impact to our consolidated financial position upon adoption will be the recognition, on a discounted basis, of our minimum commitments under noncancelable operating leases on our consolidated balance sheets resulting in the recording of right of use assets and lease obligations. Our minimum commitments under noncancelable operating leases are not significantly different than those disclosed in our 2017 Form 10-K. In June 2016 the FASB 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, resulting in recognition of lifetime expected credit losses upon loan origination.
Revenue Recognition | Revenue Recognition We adopted 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. We adopted ASU 2014-09 by applying the modified retrospective method to all noncompleted contracts as of the date of adoption. See Note 1 for additional information pertaining to the adoption of ASU 2014-09. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The following accounting policies became effective upon the adoption of ASU 2014-09. Automotive Automotive net sales and revenue represents the amount of consideration to which we expect to be entitled in exchange for vehicle, parts and accessories and services and other sales. The consideration recognized represents the amount received, typically shortly after the sale to a customer, net of estimated dealer and customer sales incentives we reasonably expect to pay. Significant factors in determining our estimates of incentives include forecasted sales volume, product type, product mix, customer behavior and assumptions concerning market conditions. Historical experience is also considered when establishing our future expectations. Subsequent adjustments to incentive estimates are possible as facts and circumstances change over time. When our customers have a right to return eligible parts and accessories, we consider the returns in our estimation of the transaction price. A portion of the consideration received is deferred for separate performance obligations, such as maintenance and vehicle connectivity, that will be provided to our customers at a future date. Taxes assessed by various government entities, such as sales, use and value-added taxes, collected at the time of the vehicle sale are excluded from Automotive net sales and revenue. Shipping and handling activities that occur after control of the vehicle transfers to the dealer are recognized at the time of sale and presented in Automotive and other cost of sales. V e hicle, Parts and Accessories For the majority of vehicle and accessories sales our customers obtain control and we recognize revenue when the vehicle transfers to the dealer, which generally occurs when the vehicle is released to the carrier responsible for transporting it to a dealer. Revenue, net of estimated returns, is recognized on the sale of parts upon delivery to the customer. Certain transfers to daily rental companies are accounted for as sales, with revenue recognized at the time of transfer. Such transactions were previously accounted for as operating leases. At the time of transfer, we defer revenue for remarketing obligations, record a residual value guarantee and reflect a deposit liability for amounts expected to be returned once the remarketing services are complete. Deferred revenue is recognized in earnings upon completion of the remarketing service. Transfers that occurred prior to January 1, 2018 and future transfers containing a substantive purchase obligation continue to be accounted for as operating leases and rental income is recognized over the estimated term of the lease. Used Vehicles Proceeds from the auction of vehicles returned from daily rental car companies are recognized in Automotive net sales and revenue upon transfer of control of the vehicle to the customer and the related vehicle carrying value is recognized in Automotive and other cost of sales. Services and Other Services and other revenue primarily consists of revenue from vehicle-related service arrangements and after-sale services such as maintenance, vehicle connectivity and extended service warranties. For those service arrangements that are bundled with a vehicle sale, a portion of the revenue from the sale is allocated to the service component and recognized as deferred revenue within Accrued liabilities or Other liabilities. We recognize revenue for bundled services and services sold separately as services are performed, typically over a period of less than three years. Automotive Financing - GM Financial Finance charge income earned on receivables is recognized using the effective interest method. Fees and commissions (including incentive payments) received and direct costs of originating loans are deferred and amortized over the term of the related finance receivables using the effective interest method and are removed from the condensed consolidated balance sheets when the related finance receivables are sold, charged off or paid in full. Accrual of finance charge income on retail finance receivables is generally suspended on accounts that are more than 60 days delinquent, accounts in bankruptcy and accounts in repossession. Payments received on nonaccrual loans are first applied to any fees due, then to any interest due and then any remaining amounts are recorded to principal. Interest accrual generally resumes once an account has received payments bringing the delinquency to less than 60 days past due. Accrual of finance charge income on commercial finance receivables is generally suspended on accounts that are more than 90 days delinquent, upon receipt of a bankruptcy notice from a borrower, or where reasonable doubt exists about the full collectability of contractually agreed upon principal and interest. Payments received on nonaccrual loans are first applied to principal. Interest accrual resumes once an account has received payments bringing the account fully current and collection of contractual principal and interest is reasonably assured (including amounts previously charged off). Income from operating lease assets, which includes lease origination fees, net of lease origination costs and incentives, is recorded as operating lease revenue on a straight-line basis over the term of the lease agreement.
Equipment on Operating Leases | Equipment on Operating Leases Equipment on operating leases, net consists of vehicle leases to retail customers with lease terms of two to five years and vehicle sales to rental car companies that are expected to be repurchased in an average of seven months. We are exposed to changes in the residual values of these assets. The residual values represent estimates of the values of the leased vehicles at the end of the lease contracts and are determined based on forecasted auction proceeds when there is a reliable basis to make such a determination. Realization of the residual values is dependent on the future ability to market the vehicles under prevailing market conditions. The adequacy of the estimate of the residual value is evaluated over the life of the arrangement and adjustments may be made to the extent the expected value of the vehicle changes. Adjustments may be in the form of revisions to the depreciation rate or recognition of an impairment charge. Impairment is determined to exist if an impairment indicator exists and the expected future cash flows, which include estimated residual values, are lower than the carrying amount of the vehicle's asset group. If the carrying amount is considered impaired an impairment charge is recorded for the amount by which the carrying amount exceeds fair value of the vehicle's asset group. Fair value is determined primarily using the anticipated cash flows, including estimated residual values. In our automotive finance operations when a leased vehicle is returned or repossessed the asset is recorded in Other assets at the lower of amortized cost or estimated selling price, less costs to sell. Upon disposition a gain or loss is recorded in GM Financial interest, operating and other expenses for any difference between the net book value of the leased asset and the proceeds from the disposition of the asset.
Marketable Debt Securities | Marketable Debt Securities We classify marketable debt securities as either available-for-sale or trading. Various factors, including turnover of holdings and investment guidelines, are considered in determining the classification of securities. Available-for-sale debt securities are recorded at fair value with unrealized gains and losses recorded net of related income taxes in Accumulated other comprehensive loss until realized. Trading debt securities are recorded at fair value with changes in fair value recorded in Interest income and other non-operating income, net. We determine realized gains and losses for all debt securities using the specific identification method. We measure the fair value of our marketable debt securities using a market approach where identical or comparable prices are available and an income approach in other cases. If quoted market prices are not available, fair values of securities are determined using prices from a pricing service, pricing models, quoted prices of securities with similar characteristics or discounted cash flow models. These prices represent non-binding quotes. Our pricing service utilizes industry-standard pricing models that consider various inputs. We conduct an annual review of our pricing service and believe the prices received from our pricing service are a reliable representation of exit prices. An evaluation is made quarterly to determine if unrealized losses related to non-trading investments in debt securities are other-than-temporary. Factors considered include the length of time and extent to which the fair value has been below cost, the financial condition and near-term prospects of the issuer and the intent to sell or likelihood to be forced to sell the debt security before any anticipated recovery.
Equity Investments | Equity Investments When events and circumstances warrant, equity investments accounted for under the equity method of accounting are evaluated for impairment. An impairment charge is recorded whenever a decline in value of an equity investment below its carrying amount is determined to be other-than-temporary. Impairment charges related to equity method investments are recorded in Equity income. Equity investments that are not accounted for under the equity method of accounting are measured at fair value with changes in fair value recorded in Interest income and other non-operating income, net.
Derivative Financial Instruments | Derivative Financial Instruments The following changes to our accounting policies became effective upon adoption of ASU 2017-12. Automotive Certain foreign currency and commodity forward contracts have been designated as cash flow hedges. The risk being hedged is the foreign currency and commodity price risk related to forecasted transactions. If the contract has been designated as a cash flow hedge, the change in the fair value of the cash flow hedge is deferred in Accumulated other comprehensive loss and is recognized in Automotive and other cost of sales along with the earnings effect of the hedged item when the hedged item affects earnings. Automotive Financing - GM Financial Certain interest rate swap and foreign currency swap agreements have been designated as cash flow hedges. The risk being hedged is the foreign currency and interest rate risk related to forecasted transactions. If the contract has been designated as a cash flow hedge, the change in the fair value of the cash flow hedge is deferred in Accumulated other comprehensive loss and is recognized in GM Financial interest, operating and other expenses along with the earnings effect of the hedged item when the hedged item affects earnings. Changes in the fair value of amounts excluded from the assessment of effectiveness are recorded currently in earnings and are presented in the same income statement line as the earnings effect of the hedged item.
