Basis of Presentation and Recent Accounting Standards [Text Block]

Basis of Presentation and Recent Accounting Standards

The accompanying condensed consolidated financial statements have been prepared 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, composed of normal recurring adjustments, 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 consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012 as filed with the SEC.

Use of Estimates in the Preparation of the Financial Statements

The condensed consolidated financial statements are prepared in conformity with U.S. GAAP, which requires the use of estimates, judgments and assumptions that affect the amounts of assets and liabilities at the reporting date and the amounts of revenue and expenses in the periods presented. We believe that the accounting estimates employed are appropriate and the resulting balances are reasonable; however, due to the inherent uncertainties in making estimates actual results could differ from the original estimates, requiring adjustments to these balances in future periods.

Venezuelan Exchange Regulations

Our Venezuelan subsidiaries utilize the U.S. Dollar as their functional currency because of the hyperinflationary status of the Venezuelan economy. The Venezuelan government has foreign exchange control regulations which make it more difficult to convert Bolivar Fuerte (BsF) to U.S. Dollars. These regulations affect our Venezuelan subsidiaries' ability to pay non-BsF denominated obligations that do not qualify to be processed by the Venezuela currency exchange agency at the official exchange rates.

The aggregate net assets denominated in BsF at March 31, 2013 and December 31, 2012 were $713 million and $940 million which included monetary assets of $1.3 billion and $1.6 billion and monetary liabilities of $0.9 billion and $1.1 billion. At March 31, 2013 and December 31, 2012 other consolidated entities have receivables from our Venezuelan subsidiaries denominated in other currencies of $299 million and $224 million. The total amounts pending government approval for settlement at March 31, 2013 and December 31, 2012 were BsF 3.3 billion (equivalent to $555 million) and BsF 2.2 billion (equivalent to $523 million), for which some requests have been pending from 2007.

In February 2013 the Venezuelan government announced that the official fixed exchange rate of BsF 4.3 to $1.00 changed to BsF 6.3 to $1.00 effective February 13, 2013. The devaluation required remeasurement of our Venezuelan subsidiaries' non-U.S. dollar denominated monetary assets and liabilities. The remeasurement resulted in a charge of $162 million in the three months ended March 31, 2013.

We believe it is possible that the Venezuelan government may further devalue the BsF against the U.S. dollar in the future. If the BsF were devalued further, it would result in a charge to our income statement in the period of devaluation. Based on our March 31, 2013 net monetary assets, a further devaluation of the BsF by 1 BsF to $1.00 would result in a charge of approximately $50 million.

Recently Adopted Accounting Principles

In the three months ended March 31, 2013, we adopted Accounting Standards Update (ASU) 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." This ASU does not change current requirements for reporting net income or other comprehensive income (OCI) in financial statements; rather, it requires certain disclosures of the amount of reclassifications of items from OCI to net income by component. The related disclosures are presented in Note 20.

Acquisition of Businesses	Acquisition of Businesses Acquisition of SAIC GM Investment Limited In September 2012 we obtained control of SAIC GM Investment Limited, the holding company of General Motors India Private Limited and Chevrolet Sales India Private Limited (collectively HKJV) through a series of transactions that resulted in us owning a 90.8% interest and we consolidated HKJV effective September 1, 2012. Acquisition of GMAC South America LLC In March 2012 we acquired from Ally Financial for cash of $29 million 100% of the outstanding equity interests of GMAC South America LLC whose only asset is GMAC de Venezuela CA (GMAC Venezuela) comprising the business and operations of Ally Financial in Venezuela. This acquisition provides us with a captive finance offering in Venezuela which we believe is important in maintaining market position and will provide continued sources of financing for our Venezuela dealers and customers. We recorded the fair value of the assets acquired and liabilities assumed as of March 1, 2012, the date we obtained control, and have included GMAC Venezuela's results of operations and cash flows from that date forward.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Marketable Securities [Abstract]

Marketable Securities

We measure the fair value of our marketable securities using a market approach where identical or comparable prices are available and an income approach in other cases. We obtain the majority of the prices used in this valuation from a pricing service. Our pricing service utilizes industry standard pricing models that consider various inputs, including benchmark yields, reported trades, broker/dealer quotes, issuer spreads and benchmark securities as well as other relevant economic measures. We conduct an annual review of valuations provided by our pricing service, which includes discussion and analysis of the inputs used by the pricing service to provide prices for the types of securities we hold. These inputs include prices for comparable securities, bid/ask quotes, interest rate yields and prepayment spreads. Based on our review we believe the prices received from our pricing service are a reliable representation of exit prices. We measure the fair value of our investment in Peugeot S.A. (PSA) common stock using the published stock price. At March 31, 2013 the fair value of our investment in PSA exceeded the carrying amount.

GM Korea Company Preferred Shares

In September 2012 we entered into a transaction to acquire security interests in certain mandatorily redeemable preferred shares issued by GM Korea Company (GM Korea) for $293 million. The transaction did not meet the criteria for an extinguishment of the liability. Subsequently, GM Korea partially redeemed the mandatorily redeemable preferred shares resulting in an extinguishment of the liability and redemption of a portion of the security interests. The remaining unredeemed interests are classified as available-for-sale corporate debt securities and had a fair value of $178 million and $177 million at March 31, 2013 and December 31, 2012.

In April 2013 GM Korea redeemed early the remaining balance of GM Korea's mandatorily redeemable preferred shares resulting in an extinguishment of the liability and redemption of the majority of our remaining security interests. For additional information on the early redemption of GM Korea's mandatorily redeemable preferred shares refer to Note 13.

GM Financial Finance Receivables, net

In April 2012 GM Financial commenced commercial lending activities in the U.S. centered on floorplan financing of dealer vehicle inventory and dealer loans to finance dealer sites, facilities, facility improvements and working capital. In March 2013 GM Financial launched similar commercial lending in Canada. These loans are made on a secured basis.

GM Financial finance receivables, net	$	11,455	$	11,752	$	10,998	$	11,313

GM Financial determined the fair value of consumer finance receivables using Level 3 inputs within a cash flow model. The Level 3 inputs reflect assumptions regarding expected prepayments, deferrals, delinquencies, recoveries and charge-offs of the loans within the finance receivable portfolio. The cash flow model produces an estimated amortization schedule of the finance receivables which is the basis for the calculation of the series of cash flows that derive the fair value of the portfolio. The series of cash flows is calculated and discounted using a weighted-average cost of capital (WACC) using unobservable debt and equity percentages, an unobservable cost of equity and an observable cost of debt based on companies with a similar credit rating and maturity profile as the portfolio. Macroeconomic factors could negatively affect the credit performance of the portfolio and therefore could potentially affect the assumptions used in GM Financial's cash flow model.

Substantially all commercial finance receivables have variable interest rates and maturities of one year. Therefore, the carrying amount is considered to be a reasonable estimate of fair value.

GM Financial purchases consumer finance contracts from automobile dealers without recourse, and accordingly, the dealer has no liability to GM Financial if the consumer defaults on the contract. Finance receivables are collateralized by vehicle titles and GM Financial has the right to repossess the vehicle in the event the consumer defaults on the payment terms of the contract.

At March 31, 2013 and December 31, 2012 the accrual of finance charge income has been suspended on delinquent consumer finance receivables based on contractual amounts due of $403 million and $503 million. At March 31, 2013 the commercial finance receivables or loans on non-accrual status were insignificant.

GM Financial reviews its pre-acquisition portfolio for differences between contractual cash flows and the cash flows expected to be collected from its initial investment in the pre-acquisition portfolio to determine if the difference is attributable, at least in part to credit quality. In the three months ended March 31, 2013 and 2012 as a result of improvements in credit performance of the pre-acquisition portfolio, which resulted in an increase of expected cash flows of $48 million and $167 million, GM Financial transferred this excess non-accretable difference to accretable yield. GM Financial will recognize this excess as finance charge income over the remaining life of the portfolio.

In the three months ended March 31, 2013 and 2012 we performed event-driven goodwill impairment tests for our GM Korea reporting unit as we determined the carrying amount of GM Korea exceeded its fair value. The fair value of GM Korea is below its carrying value due to ongoing economic weakness in certain markets to which GM Korea exports as well as higher raw material costs and unfavorable foreign currency exchange rates. The event-driven impairment tests resulted in a Goodwill impairment charge of $27 million within our GMIO segment in the three months ended March 31, 2012. Our GME reporting unit had a negative carrying amount and because it was more likely than not further goodwill impairment existed at March 31, 2012 we recorded a Goodwill impairment charge of $590 million.

The following table summarizes the Goodwill impairment charges recorded in the three months ended March 31, 2012 (dollars in millions):



	Three Months Ended March 31, 2012
	GMNA		GME(a)		GMIO		GMSA		Total Automotive		GM Financial		Total
Impairment charges	$	—	$	590	$	27	$	—	$	617	$	—	$	617

________


(a)	At March 31, 2012 GME's Goodwill balance was $0.

The impairment charges recorded as part of the event-driven goodwill impairment tests in the three months ended March 31, 2012 represent the net decreases in implied goodwill resulting primarily from decreases in the fair value-to-U.S. GAAP differences attributable to those assets and liabilities that gave rise to goodwill upon our application of fresh-start reporting. The net decreases resulted primarily from a decrease in our nonperformance risk and an improvement in our incremental borrowing rates since July 10, 2009. In addition, for the purpose of deriving an implied goodwill balance, deterioration in the business outlook for GME resulted in a reduction in the fair value of certain tax attributes and an increase in the fair value of estimated employee benefit obligations. The amount of implied goodwill derived from GM Korea decreased in the three months ended March 31, 2012 primarily from a reduction in the fair value of certain tax attributes.

When performing our goodwill impairment testing, the fair values of our reporting units were determined based on valuation techniques using the best available information, primarily discounted cash flow projections. We make significant assumptions and estimates about the extent and timing of future cash flows, growth rates, market share and discount rates that represent unobservable inputs into our valuation methodologies. The cash flows are estimated over a significant future period of time, which makes those estimates and assumptions subject to a high degree of uncertainty. Where available and as appropriate, comparative market multiples and the quoted market price of our common stock are used to corroborate the results of the discounted cash flow method.

The following table summarizes the Goodwill balances and key assumptions, which are unobservable, utilized for each of our reporting units that required a Step 2 analysis (dollars and industry volumes in millions):



							Industry Volumes(a)		Market Share(a)
	Goodwill(b)		WACC		Long-Term Growth Rates		2012/2013	2015/2016	2012/2013		2015/2016
GME - At March 31, 2012	$	594	17.5	%	0.5	%	19.1	21.9	6.2	%	6.3	%
GM Korea - At March 31, 2012(c)	$	564	14.8	%	3.0	%	81.0	97.1	1.4	%	1.1	%
GM Korea - At March 31, 2013(c)	$	450	14.3	%	3.0	%	86.2	99.7	1.1	%	1.2	%

_________


(a)	GME forecast volumes are 2012 through 2016. GM Korea forecast volumes at March 31, 2012 are 2012 through 2015 and are 2013 through 2016 at March 31, 2013.


(b)	Represents the balance of Goodwill evaluated for impairment under the Step 2 analysis.


(c)	Industry forecast volumes and market share for GM Korea are based on global industry volumes because GM Korea exports vehicles globally.

The WACCs considered various factors including bond yields, risk premiums and tax rates; the terminal values were determined using a growth model that applied a reporting unit's long-term growth rate to its projected cash flows beyond the forecast period; and industry volumes and a market share for each reporting unit included annual estimates through the forecast period. In addition minimum operating cash needs that incorporate specific business, economic and regulatory factors giving rise to varying cash needs were estimated.

Because the fair value of goodwill can be measured only as a residual amount and cannot be determined directly we calculated the implied goodwill, which utilized Level 3 measures, for the GME and GM Korea reporting units in the same manner that goodwill is recognized in a business combination pursuant to Accounting Standards Codification (ASC) 805, "Business Combinations." At March 31, 2012 our Step 2 analyses indicated GME's and GM Korea's implied goodwill was less than their recorded goodwill; therefore, Goodwill was adjusted as of that date. At March 31, 2013 GM Korea's implied goodwill exceeded its recorded goodwill.

Future goodwill impairments could be recognized should economic uncertainty continue, our equity price decline on a sustained basis, global economies enter into another recession and industry growth stagnates, or should we release deferred tax asset valuation allowances in certain tax jurisdictions. In these circumstances future goodwill impairments would largely be affected by decreases in either the fair value of a reporting unit or in the fair value-to-U.S.-GAAP differences that have occurred subsequent to our application of fresh-start reporting, which in the future would primarily occur upon a decline in the fair value of GM Financial or reversal of our remaining deferred tax asset valuation allowances. Any declines would have a negative effect on our earnings.

Our fair value estimates for event-driven impairment tests assume the achievement of the future financial results contemplated in our forecasted cash flows and there can be no assurance that we will realize that value. The estimates and assumptions used are subject to significant uncertainties, many of which are beyond our control, and there is no assurance that anticipated financial results will be achieved.

In December 2012 we entered into a product development agreement with PSA to collaborate on the development of certain vehicle platforms, components and modules. As a result of this agreement, in the three months ended March 31, 2013, we acquired the rights to certain intellectual property and technology for total consideration of Euro 500 million (equivalent to $642 million). Consideration of Euro 155 million (equivalent to $199 million) is expected to be paid in cash during 2013 with the remaining consideration to be paid in cash or in-kind exchanges by May 2018. The acquired rights were recorded at the present value of the total payments to be made as technology and intellectual property of $594 million.

Variable Interest Entities

Consolidated VIEs

Automotive

Variable interest entities (VIEs) that we do not control through a majority voting interest that are consolidated because we are the primary beneficiary include certain vehicle assembling, manufacturing and selling venture arrangements, the most significant of which is GM Egypt. At March 31, 2013 and December 31, 2012: (1) Total assets of these VIEs were $514 million and $436 million, which were composed of Cash and cash equivalents, Accounts and notes receivable, net, Inventories and Property, net; and (2) Total liabilities were $343 million and $254 million, which were composed of Accounts payable (principally trade) and Accrued liabilities. In the three months ended March 31, 2013 and 2012 Total net sales and revenue recorded by these VIEs were $236 million and $236 million and Net income (loss) was $18 million and $(5) million. These amounts are stated prior to intercompany eliminations. Liabilities recognized as a result of consolidating VIEs generally do not represent claims against us or our other subsidiaries and assets recognized generally are for the benefit of the VIEs' operations and cannot be used to satisfy our obligations.

GM Korea and HKJV are non-wholly owned consolidated subsidiaries that we control through a majority voting interest. They are also VIEs because in the future they may require additional subordinated financial support.

The following table summarizes the liabilities of GM Korea and HKJV for which their creditors do not have recourse to our general credit (dollars in millions):

Automotive Financing - GM Financial

GM Financial finances its loan and lease origination volume through the use of credit facilities and securitization trusts that issue asset-backed securities to investors. GM Financial retains a residual interest in these entities and is not required to provide any additional financial support to its sponsored credit facilities and securitization SPEs. The SPEs are considered VIEs because they do not have sufficient equity at risk and are consolidated because GM Financial has the power over those activities that most significantly affect the economic performance of the SPEs. The finance receivables, leased assets and other assets held by these subsidiaries are not available to our creditors or creditors of our other subsidiaries. Refer to Notes 5, 6 and 13 for additional information on GM Financial's involvement with the SPEs.

Nonconsolidated VIEs

Automotive

VIEs that are not consolidated include certain vehicle assembling, manufacturing and selling venture arrangements and other automotive related entities to which we provided financial support including HKJV prior to September 2012 and Ally Financial. We concluded these entities are VIEs because they do not have sufficient equity at risk or may require additional subordinated financial support. We currently lack the power through voting or similar rights to direct those activities of these entities that most significantly affect their economic performance. Our variable interests in these nonconsolidated VIEs include accounts and notes receivable, equity in net assets, guarantees and financial support, some of which were provided to certain current or previously divested suppliers in order to ensure that supply needs for production were not disrupted due to a supplier's liquidity concerns or possible shutdowns.

The following table summarizes the amounts recorded for nonconsolidated VIEs and the related off-balance sheet guarantees and maximum exposure to loss (dollars in millions):

Fair Value of Ally Financial Common Stock

At March 31, 2013 and December 31, 2012 we held a 9.9% common equity ownership in Ally Financial. Our entire equity ownership is held indirectly through an independent trust which has the sole authority to vote the shares and is required to dispose of all Ally Financial common stock by December 24, 2013.

We estimated the fair value of Ally Financial common stock using a market approach that applies the average price to tangible book value multiples of comparable companies to the consolidated Ally Financial tangible book value. The significant inputs used in our fair value analyses included Ally Financial's March 31, 2013 and December 31, 2012 financial statements, financial statements and price to tangible book value multiples of comparable companies in the banking and finance industry, and the effects of certain Ally Financial shareholder rights. The measurement of Ally Financial common stock is a Level 3 fair value measurement.

The following table summarizes the carrying amount and estimated fair value of Ally Financial common stock (dollars in millions):

Impairment charges of long-lived assets(a)	$	19	$	31
Depreciation of equipment on operating leases	$	108	$	92
Impairment charges of equipment on operating leases	$	50	$	55

__________


(a)	The fair value of related assets was determined to be $0 in the three months ended March 31, 2013 and 2012 measured utilizing Level 3 inputs. Fair value measurements of long-lived assets utilized projected cash flows discounted at a rate commensurate with the perceived business risks related to the assets involved.

The following table summarizes equipment on operating leases to daily rental car companies measured at fair value utilizing Level 3 inputs on a nonrecurring basis (dollars in millions):



	Fair Value Measures(a)
Three months ended March 31, 2013	$	1,101

__________


(a)	The carrying amount of the related assets at March 31, 2013 and 2012 may no longer equal the fair value as the fair value presented is as of the date the impairment charge was recorded during the period presented.

Impairment of vehicles leased to daily rental car companies with guaranteed repurchase obligations is determined to exist if the expected cash flows are lower than the carrying amount of the vehicle. We have multiple, distinct portfolios of vehicles leased to rental car companies and may have multiple impairments within a period. Expected cash flows include all estimated net revenue and costs associated with the sale to daily rental car companies through disposal at auction. The fair value measurements are determined, reviewed and approved on a monthly basis by personnel with appropriate knowledge of transactions with daily rental car companies and auction transactions.

The following table summarizes the carrying amount and fair value of debt (dollars in millions):



	March 31, 2013		December 31, 2012
Carrying amount	$	5,175	$	5,172
Fair value(a)	$	5,241	$	5,298

__________


(a)	The fair value of debt included $4.0 billion and $4.1 billion measured utilizing Level 2 inputs at March 31, 2013 and December 31, 2012. The fair value of debt included $1.2 billion measured utilizing Level 3 inputs at March 31, 2013 and December 31, 2012.

The Level 2 fair value measurements utilize a discounted cash flow model. The valuation is reviewed internally by personnel with appropriate expertise in valuation methodologies. This model utilizes observable inputs such as contractual repayment terms and benchmark yield curves, plus a spread that is intended to represent our nonperformance risk for secured or unsecured obligations. We estimate our nonperformance risk using our corporate credit rating, the rating on our secured revolver, yields on traded bonds of companies with comparable credit ratings and risk profiles. We acquire the benchmark yield curves and nonperformance risk spread from independent sources that are widely used in the financial industry. In certain circumstances we adjust the valuation of debt for additional nonperformance risk or potential prepayment probability scenarios. We may use a probability weighting of prepayment scenarios when the stated rate exceeds market rates and the instrument contains prepayment features. The prepayment scenarios are adjusted to reflect the views of market participants. The fair value measurements subject to additional adjustments for nonperformance risk or prepayment have been categorized within Level 3.

Losses on Extinguishment of Debt

In April 2013 we made a payment of Korean Won (KRW) 794 billion (equivalent to $696 million) to redeem early the remaining balance of GM Korea's mandatorily redeemable preferred shares that had a carrying amount of KRW 525 billion (equivalent to $460 million). We recorded the difference of KRW 269 billion (equivalent to $236 million) as a loss on extinguishment of debt in April 2013. The KRW to U.S. Dollar amounts were determined using the spot rate at the date of transaction; actual amounts will be recorded using the average rate for the month.

In the three months ended March 31, 2012 we prepaid and retired a debt obligation of $39 million. We recorded a loss on extinguishment of debt of $18 million which primarily represented the unamortized debt discount.

Secured Revolving Credit Facilities

We have two secured revolving credit facilities with an aggregate borrowing capacity of $11.0 billion. These facilities consist of a three-year, $5.5 billion facility and a five-year, $5.5 billion facility. Availability under the secured revolving credit facilities is subject to borrowing base restrictions.

The facilities allow for borrowing in U.S. dollars and other currencies, subject to certain sub-limits, and the three-year facility includes a GM Financial borrowing sub-limit of $4.0 billion. We had amounts in use under the letter of credit sub-facility under the three-year facility of $344 million and $207 million at March 31, 2013 and December 31, 2012.

Total GM Financial debt		$	13,249	$	13,510	$	10,878	$	11,145

The carrying amount of the credit facilities is considered to be a reasonable estimate of fair value because these facilities have variable rates of interest and maturities of approximately one year. The fair value of the securitization notes payable and senior notes are based on quoted market prices, when available. If quoted prices are not available the market value is estimated by discounting future net cash flows expected to be settled using a current risk-adjusted rate.

GM Financial uses observable and unobservable inputs to estimate fair value for the private securitization 2012-PP1. Unobservable inputs are related to the structuring of the debt into various classes, which is based on public securitizations issued during the same time frame. Observable inputs are used by obtaining active prices based on the securitization debt issued during the same time frame. These observable inputs are then used to create expected market prices (unobservable inputs), which are then applied to the debt classes in order to estimate fair value which would approximate market value.

Credit Facilities

The following table summarizes further details regarding terms and availability of GM Financial's credit facilities at March 31, 2013 (dollars in millions):



	Facility Amount		Advances Outstanding		Assets Pledged		Restricted Cash Pledged(a)

Significant Plan Amendments, Benefit Modifications and Related Events

U.S. Salaried Defined Benefit Pension Plan

In January 2012 we amended the salaried pension plan to cease the accrual of additional benefits effective September 30, 2012. This amendment resulted in a curtailment which decreased the pension liability and decreased the net pre-tax actuarial loss component of Accumulated other comprehensive loss by $309 million in the three months ended March 31, 2012. Active plan participants started receiving additional contributions in the defined contribution plan in October 2012.

Remeasurements

In the three months ended March 31, 2012 certain pension plans in GME were remeasured as part of our Goodwill impairment testing, resulting in an increase of $150 million in the pension liability and a pre-tax increase in the net actuarial loss component of Accumulated other comprehensive loss.

Refer to Note 9 for additional information on our Goodwill impairment.

Derivative Financial Instruments and Risk Management

Automotive

Derivatives and Hedge Accounting

In accordance with our risk management policy we enter into a variety of foreign currency exchange rate and commodity derivative contracts to manage our exposure to fluctuations in certain foreign currency exchange rates and commodity prices. At March 31, 2013 and December 31, 2012 our derivative instruments consisted primarily of forward contracts and options, none of which were designated in hedging relationships.

We manage our counterparty credit risk by monitoring the credit ratings of our counterparties and by requiring them to post collateral in certain circumstances. Master netting agreements are entered into with counterparties that include a provision to allow the set-off of certain amounts in order to manage counterparty credit risk.

Such master netting agreements with counterparties are based on International Swaps and Derivatives Association, Inc. guidelines and are modified as required. These agreements provide a right to offset corresponding amounts at the option of the non-defaulting party or non-affected party upon the early termination of these agreements by default, upon certain other termination events and a credit event upon merger. To the extent that any amounts are offset with notice to the counterparty, the offset amounts are discharged in all respects.

Certain of our agreements with counterparties require that we either receive or provide cash collateral. At March 31, 2013 and December 31, 2012 no collateral was provided to counterparties; however, we have received collateral from counterparties related to certain derivative instruments. We are not subject to any covenants requiring the maintenance of certain credit rating levels or credit risk ratios that would require the posting of collateral in the event that such covenants are violated.

Offsetting of Derivatives

Our policy is to present derivative assets and liabilities on a gross basis. The potential effect from offsetting those derivative assets and liabilities that are subject to master netting agreements is insignificant.

Fair Value of Derivatives

The following tables summarize fair value measurements of our derivative instruments measured on a recurring basis (dollars in millions):

We measure the fair value of our portfolio of foreign currency, commodity and embedded derivatives using industry accepted models. The significant Level 2 inputs used in the valuation of our derivatives include spot rates, forward rates, volatility and interest rates. These inputs are obtained from pricing services, broker quotes and other sources.

We are party to agreements in which pricing is affected by movements in commodity prices or currency exchange rates. Therefore we determined these agreements to be derivatives or have embedded derivatives for accounting purposes. The valuations of these derivatives use Level 3 inputs. Unobservable inputs include foreign currency forward exchange rates, volume commitments and vehicle mix and current and forward commodity prices.

The valuations are performed, reviewed and approved by personnel with appropriate expertise in valuation methodologies. For certain derivatives we compare our own valuations with valuations prepared by independent outside parties.

The following table summarizes the activity for our derivative investments measured using Level 3 inputs (dollars in millions):

Automotive Financing - GM Financial

GM Financial is exposed to market risks arising from adverse changes in interest rates due to floating interest rate exposure on its credit facilities and on certain securitization notes payable and manages this exposure with interest rate swaps and caps. GM Financial had interest rate derivatives in asset positions with notional amounts of $1.7 billion and $775 million at March 31, 2013 and December 31, 2012. GM Financial had interest rate derivatives in liability positions with notional amounts of $1.7 billion and $775 million at March 31, 2013 and December 31, 2012. The fair value of these derivative financial instruments was insignificant.

In connection with the anticipated closing of the acquisition of certain Ally Financial international operations, GM Financial provided a loan denominated in foreign currencies (Euro, British Pound and Swedish Krona) to an acquired entity for the equivalent of $1.5 billion. In March 2013 GM Financial entered into foreign currency exchange swaps to hedge against any valuation change in the loan due to changes in foreign exchange rates. At March 31, 2013 the notional amount of the foreign currency exchange swaps was $1.5 billion. The fair value of the foreign currency exchange swaps was insignificant. Refer to Note 24 for additional information on the acquisition.

(e)	Primarily various non-U.S. labor related matters and indirect tax-related litigation.

Guarantees

We provide payment guarantees on commercial loans outstanding with third parties, such as dealers or rental car companies. These guarantees either expire in 2018 or are ongoing. We determined the fair value ascribed to the guarantees at inception and subsequent to inception to be insignificant based on the credit worthiness of the third parties.

We have agreements with third parties that guarantee the fulfillment of certain suppliers' commitments and other obligations. These guarantees expire in 2013 through 2017 or are ongoing, or upon the occurrence of specific events.

In some instances certain assets of the party whose debt or performance we have guaranteed may offset, to some degree, the cost of the guarantee. The offset of certain of our payables to guaranteed parties may also offset certain guarantees, if triggered. 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.

In connection with certain divestitures of assets or operating businesses, we have entered into agreements indemnifying certain buyers and other parties with respect to environmental conditions and other closure costs pertaining to real property we owned. 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. Immaterial 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.

In addition to the guarantees and indemnifying agreements previously discussed, we indemnify dealers for certain product liability related claims as subsequently discussed.

With respect to other product-related claims involving products manufactured by certain joint ventures, we believe that costs incurred are adequately covered by recorded accruals. These guarantees terminate in years ranging from 2020 to 2026.

Environmental Liability

Automotive operations, like operations of other companies engaged in similar businesses, are subject to a wide range of environmental protection laws, including laws regulating air emissions, water discharges, waste management and environmental remediation. We are in various stages of investigation or remediation for sites where contamination has been alleged. We are involved in a number of actions to remediate hazardous wastes as required by federal and state laws. Such statutes require that responsible parties fund remediation actions regardless of fault, legality of original disposal or ownership of a disposal site.

The future effect of environmental matters, including potential liabilities, is often difficult to estimate. An environmental reserve is recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. This practice is followed whether the claims are asserted or unasserted. Recorded liabilities are not reduced for possible recoveries from insurance carriers or other parties. Liabilities have been recorded for the expected costs to be paid over the periods of remediation for the applicable sites, which typically range from five to 30 years.

For many sites the remediation costs and other damages for which we ultimately may be responsible may vary because of uncertainties with respect to factors such as the connection to the site or to materials there, the involvement of other potentially responsible parties, the application of laws and other standards or regulations, site conditions and the nature and scope of investigations, studies and remediation to be undertaken (including the technologies to be required and the extent, duration and success of remediation).

The final outcome of environmental matters cannot be predicted with certainty at this time. Subsequent adjustments to initial estimates are recorded as necessary based upon additional information obtained. In future periods new laws or regulations, advances in remediation technologies and additional information about the ultimate remediation methodology to be used could significantly change our estimates. It is possible that the resolution of one or more environmental matters could exceed the amounts accrued in an amount that could be material to our financial condition, results of operations and cash flows. At March 31, 2013 we estimate the remediation losses could range from $120 million to $250 million.

Product Liability

With respect to product liability claims involving our and Old GM's 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. Although punitive damages are claimed in some of these lawsuits and such claims are inherently unpredictable, accruals incorporate historic experience with these types of claims. Liabilities have been recorded 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. These amounts were recorded in Accrued liabilities and Other liabilities and deferred income taxes.

We indemnify dealers for certain product liability related claims including products sold by Old GM. We monitor actual claims experience and make periodic adjustments to our estimates. Based on both management's judgment concerning the projected number and value of both dealer indemnification obligations and product liability claims, we have applied actuarial methodologies and estimated the liability. We expect our product liability reserve to rise in future periods as new claims arise from incidents subsequent to July 9, 2009.

Other Litigation-Related Liability and Tax Administrative Matters

Various legal actions, governmental investigations, claims and proceedings are pending against us including matters arising out of alleged product defects; employment-related matters; governmental regulations relating to safety, emissions and fuel economy; product warranties; financial services; dealer, supplier and other contractual relationships; tax-related matters not recorded pursuant to ASC 740, "Income Taxes" (indirect tax-related matters) and environmental matters.

With regard to the litigation matters discussed in the previous paragraph, reserves have been established for matters in which we believe that losses are probable and can be reasonably estimated, the majority of which are associated with non-U.S. labor-related matters as well as indirect tax-related matters. 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. 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. Certain South American administrative proceedings are indirect tax-related and may require that we deposit funds in escrow. Escrow deposits may range from $500 million to $700 million. 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 March 31, 2013. We believe that appropriate accruals have been established for such matters based on information currently available. Reserves for litigation losses are recorded in Accrued liabilities and Other liabilities and deferred income taxes. Litigation is inherently unpredictable however; and unfavorable resolutions could occur. Accordingly it is possible that an adverse outcome from such proceedings could exceed the amounts accrued in an amount that could be material to our financial condition, results of operations and cash flows in any particular reporting period.

GM Korea Wage Litigation

Commencing on or about September 29, 2010 current and former hourly employees of GM Korea filed seven 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 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) issued a decision affirming a decision of the Incheon District Court in a case involving five GM Korea employees which was contrary to GM Korea's position in all of these cases. Although GM Korea believes the decision of the Seoul High Court is incorrect and has appealed to the Supreme Court of the Republic of Korea, at March 31, 2013 we have an accrual of KRW 778 billion (equivalent to $699 million) in connection with these cases. We do not believe we have any reasonably possible exposure in excess of the amount of the accrual. Both the scope of claims asserted and GM Korea's assessment of any or all of individual claim elements may change if new information becomes available.

GMCL Dealers' Claim

On February 12, 2010 a claim was filed in the Ontario Superior Court of Justice against General Motors of Canada Limited (GMCL) on behalf of a purported class of over 200 former GMCL dealers (the Plaintiff Dealers) which had entered into wind-down agreements with GMCL. In May 2009 in the context of the global restructuring of the business and the possibility that GMCL might be required to initiate insolvency proceedings, GMCL offered the Plaintiff Dealers the wind-down agreements to assist with their exit from the GMCL dealer network and to facilitate winding down their operations in an orderly fashion by December 31, 2009 or such other date as GMCL approved but no later than on October 31, 2010. The Plaintiff Dealers allege that the Dealer Sales and Service Agreements were wrongly terminated by GMCL and that GMCL failed to comply with certain disclosure obligations, breached its statutory duty of fair dealing and unlawfully interfered with the Plaintiff Dealers' statutory right to associate in an attempt to coerce the Plaintiff Dealers into accepting the wind-down agreements. The Plaintiff Dealers seek damages and assert that the wind-down agreements are rescindable. The Plaintiff Dealers' initial pleading makes reference to a claim “not exceeding” CAD $750 million, without explanation of any specific measure of damages. On March 1, 2011 the court approved certification of a class for the purpose of deciding a number of specifically defined issues including: (1) whether GMCL breached its obligation of "good faith" in offering the wind-down agreements; (2) whether GMCL interfered with the Plaintiff Dealers' rights of free association; (3) whether GMCL was obligated to provide a disclosure statement and/or disclose more specific information regarding its restructuring plans in connection with proffering the wind-down agreements; and (4) assuming liability, whether the Plaintiff Dealers can recover damages in the aggregate (as opposed to proving individual damages). On June 22, 2011 the court granted GMCL permission to appeal the class certification decision. On March 26, 2012 the Ontario Superior Court dismissed GMCL's appeal of the class certification order. Accordingly the case will proceed as a class action. Twenty-six dealers within the certified class definition have indicated that they will not participate. The current prospects for liability are uncertain, but because liability is not deemed probable we have no accrual relating to this litigation. We cannot estimate the range of reasonably possible loss in the event of liability as the case presents a variety of different legal theories, none of which GMCL believes are valid.

UAW Claim

On April 6, 2010 the International Union, United Automobile, Aerospace and Agriculture Implement Workers of America (UAW) filed suit against us in the U.S. District Court for the Eastern District of Michigan claiming that we breached an obligation to contribute $450 million to the UAW Retiree Medical Benefits Trust. The UAW alleges that we were contractually required to make this contribution. The reasonably possible loss as defined by ASC 450, “Contingencies” is $450 million, which is the amount claimed. We believe that the claim is without merit and we have no accrual relating to this litigation. We believe the UAW's claim is barred by the 2009 UAW Retiree Settlement Agreement approved by the U.S. Bankruptcy Court for the Southern District of New York (Bankruptcy Court). We also maintain that Delphi Corporation's bankruptcy plan of reorganization did not fulfill the applicable conditions of the relevant agreement and therefore payment would not be due even in the absence of the 2009 UAW Retiree Settlement Agreement.

Nova Scotia Claims Litigation

We are a participating party-in-interest in proceedings pending in the Bankruptcy Court to adjudicate claims in the Old GM bankruptcy arising from certain securities issued by General Motors Nova Scotia Finance Company (Nova Scotia Finance), an Old GM subsidiary which we did not acquire in 2009 (Nova Scotia Claims Litigation). Although the current proceedings involve no claims against us, they present issues which, depending upon their resolution, could result in future claims against GMCL.

In 2003 Nova Scotia Finance, a Nova Scotia unlimited liability company, issued notes of 600 million British Pounds which were guaranteed by Old GM (Guaranty) (collectively, the Nova Scotia Notes). The proceeds of the Nova Scotia Notes were converted to CAD and loaned by Nova Scotia Finance to GMCL by means of two intercompany loans totaling CAD $1.3 billion. As part of the bankruptcy proceeding these intercompany loans were compromised for CAD $399 million pursuant to a transaction defined by a Lock-Up Agreement between GMCL, Nova Scotia Finance, Old GM and certain holders of the Nova Scotia Notes (Noteholders). The Lock-Up Agreement defined a transaction by which the Noteholders consented to, among other things, the compromise of the intercompany loans in exchange for payment of CAD $399 million as a Consent Fee. The Consent Fee was originally financed by a loan from Old GM to GMCL immediately prior to the Old GM bankruptcy filing. That loan was subsequently repaid. Pursuant to the terms of the Lock-Up Agreement, the Consent Fee did not reduce the principal amount outstanding under the Nova Scotia Notes or the Guaranty. We acquired Old GM's interest in the Lock-Up Agreement in 2009.

In the Nova Scotia Claims Litigation the Noteholders seek an allowed claim in the Old GM bankruptcy based on the Guaranty. The trustee of Nova Scotia Finance seeks an allowed claim in the amount of the deficiency between Nova Scotia Finance's assets and liabilities by reason of the fact that it is an unlimited liability company and Old GM was its sole shareholder. The claim asserted by the trustee includes sums allegedly owed by Nova Scotia Finance to us by reason of currency swaps entered into between Old GM and Nova Scotia Finance which we contend we acquired from Old GM in 2009. Allowance of the claims is opposed by the GUC Trust which asserts that the claims of the trustee and Noteholders are duplicative, that they should be reduced by the amount of the Consent Fee and/or that they should be equitably subordinated or equitably disallowed by reason of alleged inequitable conduct by the Noteholders. In support of this position the GUC Trust has asserted that the Lock-Up Agreement is void because it was not approved by the Bankruptcy Court and was funded by Old GM, that we did not acquire MLC's interest in the Lock-Up Agreements and currency swaps and that other aspects of the sale of assets to us on July 10, 2009 may be adjusted to permit disallowance or reduction of the claims of the Noteholders and the trustee. The trial has commenced but final briefing and argument is not complete and the timing of any decision is uncertain.

Although we believe the positions taken by the GUC Trust are without merit, it is reasonably possible that the Bankruptcy Court will issue rulings adverse to our interest in the Nova Scotia Claims Litigation. Such rulings could lead to subsequent claims which, although we believe would be without merit, could adversely impact GMCL's compromise of the intercompany loans. It is impossible to estimate the reasonably possible loss which would depend upon a variety of factors including the outcome of additional litigation. However the compromise of the intercompany loans for CAD $399 million resulted in a savings to GMCL of CAD $935 million (equivalent to $921 million) which we believe represents a reasonable estimate of the approximate amount of the maximum reasonably possible loss.

Brazil Excise Tax Incentive

In October 2012 the Brazilian government issued a decree which increased an excise tax rate by 30 percentage points, but also provided an offsetting tax incentive that requires participating companies to meet certain criteria, such as local investment and fuel efficiency standards. Participating companies that fail to meet the required criteria are subject to clawback provisions and fines. At March 31, 2013 we believe it is reasonably assured that the program requirements will be met based on the current business model and available technologies.

GME Planned Spending Guarantee

As part of our Opel/Vauxhall restructuring plan agreed to with European labor representatives we have committed to achieving specified milestones associated with planned spending from 2011 to 2014 on certain product programs. If we fail to accomplish the requirements set out under the agreement we will be required to pay certain amounts up to Euro 265 million for each of those years, and/or interest on those amounts, to our employees. Certain inventory with a carrying amount of $172 million and $186 million at March 31, 2013 and December 31, 2012 was pledged as collateral under the agreement. Through March 31, 2013 spending was sufficient to meet the current requirements under the agreement and the specified milestones have been accomplished. Management has the intent and believes it has the ability to meet the future requirements under the agreement.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2013
Income Tax Expense (Benefit) [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). 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. Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. In interim periods income tax expense is composed of two key elements: (1) the amount necessary to appropriately state the year to date estimated tax expense of entities included in our effective tax rate calculation, which is calculated as the difference between the amount currently estimated for the year to date period and the amount previously recorded in prior interim periods; and (2) the tax effect of unusual or infrequent items that occur in the period. In the three months ended March 31, 2013 income tax expense of $409 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation, partially offset by the U.S. research credit legislated in the three months ended March 31, 2013. In the three months ended March 31, 2012 income tax expense of $216 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. The recorded effective tax rate in the three months ended March 31, 2012 is lower than the applicable statutory tax rate due primarily to income earned in jurisdictions for which a full valuation allowance is recorded. We file income tax returns in many jurisdictions and are subject to examination by taxing authorities throughout the world. We have open tax years from 2002 to 2012 with various significant tax jurisdictions. These open years contain matters that could be subject to differing interpretations of applicable tax laws and regulations as they relate to the amount, character, timing or inclusion of revenue and expenses or the sustainability of income tax credits for a given audit cycle. In addition the global nature of our operations means that transfer pricing disputes may arise. In April 2013 we settled a previously disclosed Mexican income tax matter covering the years 2002, 2003 and 2004 for $35 million. At March 31, 2013 it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits in the next 12 months.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Restructuring and Other Initiatives [Abstract]

Restructuring and Other Initiatives [Text Block]

Restructuring and Other Initiatives

We have previously executed various restructuring and other initiatives, and we plan to execute additional initiatives in the future, if necessary, in order to align manufacturing capacity and other costs with prevailing global automotive production and 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 related to restructuring and other initiatives and charges by segment, including postemployment benefit reserves and charges (dollars in millions):

Three Months Ended March 31, 2013

GMNA recorded charges, interest accretion and other and revisions to estimates primarily related to cash severance incentive programs for skilled trade U.S. hourly employees.

Due to the expected closure of the Oshawa Consolidated Plant in June 2014, impacted employees will be eligible for a voluntary restructuring separation incentive program in accordance with the existing collective bargaining agreement that provides cash and a car voucher. This may range up to $70 million and will be included in our restructuring liability, net of existing liabilities, upon irrevocable acceptance by both parties.

GME recorded charges, interest accretion and other and revisions to estimates for previously announced separation and early retirement programs. Through March 31, 2013 the active separation programs related to Germany and the United Kingdom had a total cost of $82 million and had affected a total of 550 employees. We expect to complete these programs in 2013 and incur an additional $185 million, which will affect an additional 725 employees.

GMIO recorded charges, interest accretion and other for previously announced separation programs in Korea. Through March 31, 2013 the active separation programs related to Korea had a total cost of $43 million and had affected a total of 360 employees.

GMSA recorded charges, interest accretion and other and revisions to estimates for active separation programs. Through March 31, 2013 the active separation programs related to Brazil had a total cost of $92 million.

Three Months Ended March 31, 2012

GMNA recorded charges, interest accretion and other and revisions to estimates primarily related to our 2011 UAW labor agreement that included cash severance incentive programs which were completed at March 31, 2012 for skilled trade U.S. hourly employees. A total of 1,400 skilled trade U.S. hourly employees participated in these programs at a total cost of $99 million and was recorded upon irrevocable acceptances by both parties.

GME recorded charges, interest accretion and other and revisions to estimates primarily related to previously announced separation and early retirement programs in Germany. Through March 31, 2012 the separation programs had a total cost of $313 million and affected a total of 1,900 employees.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings Per Share

In the three months ended March 31, 2013 and 2012 we were required to use the two-class method for calculating basic earnings per share and the more dilutive of the two-class or the if-converted method to calculate diluted earnings per share as the applicable market value of our common stock was below $33.00 per common share in the periods ended March 31, 2013 and 2012. Under the two-class method for computing earnings per share, undistributed earnings are allocated to common stock and the Series B Preferred Stock according to their respective participation rights in undistributed earnings, as if all the earnings for the period had been distributed. This allocation to the Series B Preferred Stock holders reduced Net income attributable to common stockholders, resulting in a lower basic and dilutive earnings per share amount. Variability may result in our calculation of earnings per share from period to period depending on whether the application of the two-class method is required.

Basic and diluted earnings per share are computed by dividing Net income attributable to common stockholders by the weighted-average common shares outstanding in the period. Diluted earnings per share is computed by giving effect to all potentially dilutive securities that were outstanding.

The following table summarizes basic and diluted earnings per share (in millions, except for per share amounts):

(c)	Includes cumulative dividends on preferred stock of $215 million and earnings of $87 million that have been allocated to the Series B Preferred Stock holders in the three months ended March 31, 2013 and cumulative dividends on preferred stock of $215 million and earnings of $90 million that have been allocated to the Series B Preferred Stock holders in the three months ended March 31, 2012.

Three Months Ended March 31, 2013 and 2012

The application of the two-class method resulted in an allocation of undistributed earnings to our Series B Preferred Stock holders and, accordingly, 152 million common stock equivalents from the assumed conversion of the Series B Preferred Stock are not considered outstanding for purposes of determining the weighted-average common shares outstanding in the computation of diluted earnings per share in the three months ended March 31, 2013 and 2012.

MLC distributed all of its 272 million warrants for our common stock to its unsecured creditors and the GUC Trust. The warrant holders may exercise the warrants at any time prior to their respective expiration dates. Upon exercise of the warrants the shares issued will be included in the number of basic shares outstanding used in the computation of earnings per share.

Warrants to purchase 312 million and 313 million shares of our common stock were outstanding at March 31, 2013 and 2012, of which 46 million shares were not included in the computation of diluted earnings per share because the warrants' exercise price was greater than the average market price of the common shares. Under the treasury stock method, the assumed exercise of the remaining warrants resulted in 134 million and 116 million dilutive shares in the three months ended March 31, 2013 and 2012.

Diluted earnings per share included the effect of 12 million and 18 million unvested RSUs granted to certain global executives in the three months ended March 31, 2013 and 2012.

Stock Incentive Plans

Long-Term Incentive Plan

We granted 6 million RSUs valued at the grant date fair value of our common stock in the three months ended March 31, 2013 and 2012. Substantially all of these awards vest over a three-year service period, as defined in the terms of each award. We have elected to record compensation cost for these awards on a straight-line basis over the entire vesting period. Our policy is to issue new shares upon settlement of RSUs.

The 2013 awards granted to the Top 25 highest compensated employees will settle on the second and third anniversary dates of grant in 25% increments consistent with the terms of the 2009 Long-Term Incentive Plan. The awards for the Next 75 highest compensated employees will settle on the second and third anniversary dates of grant. The awards to the non-Top 100 highest compensated employees will settle on the first, second and third anniversary dates of grant. Vesting and subsequent settlement will generally occur based upon employment at the end of each specified service period.

The 2012 awards granted to the Top 25 highest compensated employees will settle on the second and third anniversary dates of grant in 25% increments consistent with the terms of the 2009 Long-Term Incentive Plan. The awards for the Next 75 and non-Top 100 highest compensated employees will vest and settle on the second and third anniversary dates of grant. Vesting and subsequent settlement will generally occur based upon employment at the end of each specified service period.

Salary Stock Plan

In the three months ended March 31, 2013 and 2012 a portion of each participant's salary accrued on each salary payment date converted to RSUs on a quarterly basis. The awards are fully vested and nonforfeitable upon grant, therefore compensation cost is fully recognized on the date of grant. In March 2012 we amended the plan to provide for cash settlement of awards. As a result we now settle these awards in cash and we reclassified $97 million from Capital surplus to Accrued liabilities and Other liabilities and deferred income taxes. The liability for these awards is remeasured to fair value at the end of each reporting period. Prior to this amendment it was our policy to issue new shares upon settlement of these awards.

RSUs

The following table summarizes information about the RSUs under our stock incentive plans (RSUs in millions):



	Shares		Weighted- Average Grant Date Fair Value		Weighted-Average Remaining Contractual Term In Years
RSUs outstanding at January 1, 2013	26.9		$	23.06	0.7
Granted	6.8		$	27.30
Settled	(13.8	)	$	20.33
Forfeited or expired	(0.2	)	$	24.11
RSUs outstanding at March 31, 2013	19.7		$	26.43	1.6
RSUs unvested and expected to vest at March 31, 2013	12.1		$	27.56	2.3
RSUs vested and payable at March 31, 2013	6.4		$	24.13	—

The following table summarizes compensation expense recorded for our stock incentive plans (dollars in millions):



	Three Months Ended
	March 31, 2013		March 31, 2012
Compensation expense	$	64	$	72
Income tax benefit	$	20	$	—

The compensation cost of each RSU that will be settled in equity is based on the fair value of our common stock on the date of grant or, for those RSUs reclassified from liability to equity-based awards, the fair value of our common stock as of the date of the public offering.

At March 31, 2013 the total unrecognized compensation expense for nonvested equity awards was $285 million. This expense is expected to be recorded over a weighted-average period of 2.3 years.

The total fair value of RSUs that vested in the three months ended March 31, 2013 and 2012 was $204 million and $49 million.

In the three months ended March 31, 2013 total payments of $45 million were made to settle 1.6 million RSUs under stock incentive plans. Payments made in the three months ended March 31, 2012 were insignificant.

Segment Reporting

3 Months Ended

Mar. 31, 2013

Segment Reporting [Abstract]

Segment Reporting

We analyze the results of our business through our five segments: GMNA, GME, GMIO, GMSA and GM Financial. The chief operating decision maker evaluates the operating results and performance of our automotive segments through Income (loss) before interest and income taxes, as adjusted for additional amounts, which are presented net of noncontrolling interests, and evaluates GM Financial through income before income taxes. Each segment has a manager responsible for executing our strategies. Our automotive manufacturing operations are integrated within the segments, benefit from broad-based trade agreements and are subject to regulatory requirements, such as Corporate Average Fuel Economy regulations. While not all vehicles within a segment are individually profitable on a fully allocated cost basis, those vehicles are needed in our product mix in order to attract customers to dealer showrooms and to maintain sales volumes for other, more profitable vehicles. Because of these and other factors, we do not manage our business on an individual brand or vehicle basis.

In the three months ended March 31, 2013 we changed our managerial and financial reporting structure to measure our reportable segments revenue and profitability based on the geographic area in which we sell vehicles to third party customers. The new reporting structure provides clearer profit and revenue visibility across geographic areas and identifies our profitability at the point of sale. Previously, it was based on the geographic area in which the vehicles originated and our managerial and financial reporting structure included intercompany sales and cost of sales in our segment results. Certain expenses such as engineering, warranty, recall campaigns and selling, general and administrative are allocated to the geographic area in which the vehicle is sold to third party customers. We have retrospectively revised the segment presentation for all periods presented.

Substantially all of the cars, trucks and 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 and trucks are also sold to fleet customers, including daily rental car companies, commercial fleet customers, leasing companies and governments. Sales to fleet customers are completed through the network of dealers and in some cases sold directly to fleet customers. Retail and fleet customers can obtain a wide range of aftersale 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 following four brands:



• Buick	• Cadillac	• Chevrolet	• GMC

The demands of customers outside of North America are primarily met with vehicles developed, manufactured and/or marketed under the following brands:



• Buick	• Chevrolet	• Holden	• Vauxhall
• Cadillac	• GMC	• Opel

At March 31, 2013 we also had equity ownership stakes directly or indirectly in entities through various regional subsidiaries, including GM Korea, SGM, SGMS, SGMW, FAW-GM and HKJV. These companies design, manufacture and market vehicles under the following brands:



• Alpheon	• Buick	• Chevrolet	• Wuling
• Baojun	• Cadillac	• Jiefang

Nonsegment operations are classified as Corporate. Corporate includes investments in Ally Financial, certain centrally recorded income and costs, such as interest, income taxes and corporate expenditures and certain nonsegment specific revenues and expenses.

All intersegment balances and transactions have been eliminated in consolidation.

The following tables summarize key financial information by segment (dollars in millions):

Subsequent Event

Acquisition of Certain Ally Financial International Operations

In November 2012 GM Financial entered into a definitive agreement with Ally Financial to acquire 100% of the outstanding equity interests in the top level holding companies of its automotive finance and financial services operations in Europe and Latin America and a separate agreement to acquire Ally Financial’s non-controlling equity interests in GMAC-SAIC, which conducts automotive finance and other financial services in China.

On April 1, 2013 GM Financial completed the acquisition of Ally Financial's European and Latin American automotive finance operations except for France, Portugal and Brazil. GM Financial paid approximately $2.4 billion, subject to certain closing adjustments, to acquire these businesses. In addition GM Financial repaid a $1.3 billion loan that was assumed as part of the acquisition.

GM Financial's acquisition of Ally Financial's French, Portuguese and Brazilian automotive finance operations and the equity interests in GMAC-SAIC are subject to certain regulatory and other approvals, and are expected to close in 2013 or early 2014. GM Financial expects to pay approximately $1.8 billion to close these acquisitions subject to certain closing adjustments.

GM Financial will record the fair value of the assets acquired and liabilities assumed on April 1, 2013, the date GM Financial obtained control of the operations, and include the results of their operations and cash flows in their consolidated financial statements from that date forward.

The following table summarizes certain pro forma financial information for us and the acquired entities that closed in April had these acquisitions occurred as of the first day in the periods presented, without consideration of historical transactions between the acquired operations and us, as it is impracticable to obtain such information (dollars in millions):



	Three Months Ended

Total net sales and revenue	$	37,109	$	38,010
Net income attributable to stockholders	$	1,212	$	1,362

It is not possible to reasonably estimate the nature and amount of any potential goodwill or the value of identifiable intangible assets at this time because the valuation of the assets acquired and liabilities assumed was not completed at the date of the issuance of our condensed consolidated financial statements.

Basis Of Presentation And Recent Accounting Standards (Policies)	3 Months Ended
	Mar. 31, 2013
Basis of Presentation and Significant Accounting Policies [Abstract]
Recently Adopted Accounting Principles [Text Block]	Recently Adopted Accounting Principles In the three months ended March 31, 2013, we adopted Accounting Standards Update (ASU) 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." This ASU does not change current requirements for reporting net income or other comprehensive income (OCI) in financial statements; rather, it requires certain disclosures of the amount of reclassifications of items from OCI to net income by component. The related disclosures are presented in Note 20.
Use of Estimates in the Preparation of the Financial Statements [Policy Text Block]	Use of Estimates in the Preparation of the Financial Statements The condensed consolidated financial statements are prepared in conformity with U.S. GAAP, which requires the use of estimates, judgments and assumptions that affect the amounts of assets and liabilities at the reporting date and the amounts of revenue and expenses in the periods presented. We believe that the accounting estimates employed are appropriate and the resulting balances are reasonable; however, due to the inherent uncertainties in making estimates actual results could differ from the original estimates, requiring adjustments to these balances in future periods.

- Definition

- Definition

Tabular disclosure of trading securities (and certain trading assets) which consist of all investments in certain debt and equity securities (and other assets) that are bought and held principally for the purpose of selling them in the near term (thus held for only a short period of time) or for which an entity has elected the fair value option. Trading generally reflects active and frequent buying and selling, and trading securities are generally used with the objective of generating profits on short-term differences in price, but this category of investments may also include items which are not intended to be sold in the near term or for which the fair value option has been elected.
