Basis of Presentation and Recent Accounting Standards [Abstract]
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. Recently Adopted Accounting Principles On January 1, 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 in financial statements; rather, it requires certain disclosures of the amount of reclassifications of items from other comprehensive income to net income by component. The related disclosures are presented in Note 19.

Acquisition of Businesses

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 interest in GMAC-SAIC Automotive Finance Company Limited (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; and on June 1, 2013 completed the acquisition of Ally Financial's automotive finance operations in France and Portugal. The aggregate consideration for these acquisitions was $2.6 billion, subject to certain closing adjustments, of which $65 million is contingent upon closing the acquisition of Ally Financial's Brazilian automotive finance operations described below. Acquisition-related costs were insignificant. In addition GM Financial repaid loans of $1.4 billion that were assumed as part of the acquisitions. GM Financial recorded the fair value of the assets acquired and liabilities assumed on the acquisition dates.

GM Financial's acquisition of Ally Financial's Brazilian automotive finance operations and the equity interest in GMAC-SAIC are subject to certain regulatory and other approvals and are expected to close in 2013 or early 2014 or as soon as practical thereafter. GM Financial expects to pay approximately $1.5 billion to close these acquisitions subject to certain closing adjustments.

The following table summarizes the aggregate consideration and the assets acquired and liabilities assumed at the acquisition dates before eliminations for net intercompany receivables of approximately $300 million (dollars in millions):



Cash	$	440
Restricted cash	525
Finance receivables	10,981
Other assets, including identifiable intangible assets	247
Secured and unsecured debt	(8,910		)
Other liabilities	(722		)
Identifiable net assets acquired	2,561
Goodwill resulting from the acquisition	57
Aggregate consideration	$	2,618

The fair value of finance receivables was determined using a discounted cash flow approach. The contractual cash flows were adjusted for estimated prepayments, defaults, recoveries, finance charge income and servicing costs and discounted using a discount rate commensurate with risks and maturity inherent in the finance contracts. The contractually required payments receivable, cash flows expected to be collected and fair value for finance receivables acquired with deteriorated credit quality at the acquisition date were $2.0 billion, $1.8 billion and $1.6 billion. The contractually required payments receivable, cash flows not expected to be collected and fair value for other acquired finance receivables were $10.1 billion, $130 million and $9.4 billion. The fair value of secured and unsecured debt was determined using quoted market prices when available and a discounted cash flow approach when not available.

We recorded goodwill in the amount of $57 million for the excess of the aggregate consideration over the fair value of the individual assets acquired and liabilities assumed and such amount is primarily attributed to the value of the incremental GM Financial business expected. The recorded goodwill is subject to further adjustment, pending the closing of the acquisition of the remaining international operations as well as any potential adjustments resulting from the finalization of closing balance sheet audits. Valuations and assumptions pertaining to income taxes are subject to change as additional information is obtained during the measurement period. All of the goodwill was assigned to the GM Financial segment and will be assigned to reporting units, which will be determined pending completion of the remaining acquisitions. The goodwill is not tax deductible.

The results of the acquired European and Latin American automotive finance operations are included in GM Financial's results beginning April 1, 2013 and the results of the acquired operations in France and Portugal are included in GM Financial's results beginning June 1, 2013. The following table summarizes the actual amounts of revenue and earnings included in our condensed consolidated financial statements as well as certain pro forma revenue and earnings of the combined entity had these acquisitions occurred as of January 1, 2012, without consideration of historical transactions between the acquired operations and us, as it is impracticable to obtain such information (dollars in millions):

Net income attributable to stockholders	$	54	$	1,932	$	2,629	$	3,286

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

Marketable Securities [Abstract]

Marketable Securities [Text Block]

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.

GM Financial Finance Receivables, Net

6 Months Ended

Finance Receivables, net [Abstract]

GM Financial Finance Receivables [Text Block]

GM Financial 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. In the three months ended June 30, 2013 GM Financial acquired certain international operations in Europe and Latin America from Ally Financial that conduct consumer and commercial lending activities. All of these loans were made on a secured basis.

As the result of GM Financial's acquisition of the Ally Financial international operations and our October 2010 acquisition of GM Financial, finance receivables are reported in two portfolios: pre-acquisition and post-acquisition portfolios.

The pre-acquisition finance receivables are composed of: (1) finance receivables acquired with the acquisition of GM Financial, all of which were considered to have had deterioration in credit quality; and (2) finance receivables that were considered to have had deterioration in credit quality at the time they were acquired with the acquisition of the Ally Financial international operations. The pre-acquisition portfolio will decrease over time with the amortization of the acquired receivables.

The post-acquisition finance receivables are composed of: (1) finance receivables originated in the U.S. and Canada since the acquisition of GM Financial; (2) finance receivables that were considered to have had no deterioration in credit quality at the time they were acquired with the acquisition of the Ally Financial international operations; and (3) finance receivables originated in all other countries since the applicable acquisition dates of the Ally Financial international operations. The post-acquisition portfolio is expected to grow over time as GM Financial originates new receivables.

The following table summarizes the components of consumer and commercial finance receivables, net (dollars in millions):

The following table summarizes the carrying amount and estimated fair value of GM Financial receivables, net (dollars in millions):



	June 30, 2013				December 31, 2012
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
GM Financial receivables, net	$	22,318	$	22,459	$	10,998	$	11,313

GM Financial determined the fair value of consumer finance receivables using observable and unobservable inputs within a cash flow model. The inputs reflect assumptions regarding expected prepayments, deferrals, delinquencies, recoveries and charge-offs of the loans within the portfolio. The cash flow model produces an estimated amortization schedule of the finance receivables 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 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 either have variable interest rates and maturities of one year or less, or were acquired or originated within the past six months. Therefore, the carrying amount is considered to be a reasonable estimate of fair value.

GM Financial reviews its pre-acquisition finance receivables portfolios for differences between contractual cash flows and the cash flows expected to be collected to determine if the difference is attributable, at least in part, to credit quality. In the six months ended June 30, 2013 and 2012 as a result of improvements in credit performance of the pre-acquisition finance receivables acquired with the acquisition of GM Financial, which resulted in an increase of expected cash flows of $54 million and $170 million, GM Financial transferred the amount of excess cash flows from the non-accretable difference to accretable yield. GM Financial will recognize this excess as finance charge income over the remaining life of the portfolio.

The following table summarizes the activity for accretable yield (dollars in millions):



	Three Months Ended						Six Months Ended

________


(a)	The balances and activity of the allowance for commercial loan losses included in the amounts at and for the three and six months ended June 30, 2013 and 2012 were insignificant.

Credit Quality

Consumer Finance Receivables

GM Financial uses proprietary scoring systems that measure the credit quality of the receivables using several factors, such as credit bureau information, consumer credit risk scores (e.g. FICO score), and contract characteristics. In addition to GM Financial's proprietary scoring systems, GM Financial considers other individual consumer factors, such as employment history, financial stability, and capacity to pay. Subsequent to origination, GM Financial reviews the credit quality of retail receivables based on customer payment activity. At the time of loan origination substantially all of GM Financial's international consumers have prime credit ratings. However, the consumer finance receivables originated in North America are predominantly sub-prime. The following table summarizes the credit risk profile by FICO score band, determined at origination of the consumer finance receivables in North America (dollars in millions):



	June 30, 2013				December 31, 2012
	Amount		%		Amount		%
FICO Score less than 540	$	3,338	29.3	%	$	3,011	27.4	%
FICO Score 540 to 599	5,301		46.6	%	5,014		45.6	%
FICO Score 600 to 659	2,397		21.1	%	2,513		22.9	%
FICO Score 660 and greater	343		3.0	%	455		4.1	%
Balance at end of period	$	11,379	100.0	%	$	10,993	100.0	%

Commercial Finance Receivables

GM Financial's commercial finance receivables consist of dealer financings. A proprietary model is used to assign a risk rating to each dealer. A credit review of each dealer is performed at least annually and, if necessary, the dealer's risk rating is adjusted on the basis of the review.

A summary of the credit risk profile by dealer grouping of the commercial finance receivables is as follows (dollars in millions):



	June 30, 2013		December 31, 2012
Group I - Dealers with strong to superior financial metrics	$	240	$	99
Group II - Dealers with fair to favorable financial metrics	881		278
Group III - Dealers with marginal to weak financial metrics	2,017		171
Group IV - Dealers with poor financial metrics	780		12
Group V - Dealers warranting special mention due to potential weaknesses	415
Group VI - Dealers with loans classified as impaired	1
	$	4,334	$	560

The credit lines for Group VI dealers are suspended, and no further funding is extended to these dealers.

Delinquency

An account is considered delinquent if a substantial portion of a scheduled payment has not been received by the date such payment was contractually due. At June 30, 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 $472 million and $503 million. At June 30, 2013 the commercial finance receivables or loans on non-accrual status were insignificant.

Consumer Finance Receivables

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.

The following table summarizes the contractual amount of delinquent contracts, which is not materially different than the recorded investment of the consumer finance receivables (dollars in millions):



	June 30, 2013				June 30, 2012
	Amount		Percent of Contractual Amount Due		Amount		Percent of Contractual Amount Due
Delinquent contracts
31-to-60 days	$	645	3.4	%	$	428	4.1	%
Greater-than-60 days	253		1.4	%	158		1.5	%
Total finance receivables more than 30 days delinquent	898		4.8	%	586		5.6	%
In repossession	35		0.2	%	25		0.3	%
Total finance receivables more than 30 days delinquent or in repossession	$	933	5.0	%	$	611	5.9	%

Impaired Finance Receivables - Troubled Debt Restructurings

Consumer finance receivables in the post-acquisition portfolio that become classified as troubled debt restructurings (TDRs) because of payment deferral or other reasons are separately assessed for impairment. A specific allowance is estimated based on the present value of the expected future cash flows of the receivable discounted at the loan's original effective interest rate.

The following table summarizes the outstanding recorded investment for consumer finance receivables that are considered to be TDRs and the related allowance (dollars in millions):



	June 30, 2013			December 31, 2012
Outstanding recorded investment	$	471		$	228
Less: allowance for loan losses	(71		)	(32		)

Equity in Net Assets of Nonconsolidated Affiliates

Nonconsolidated affiliates are entities in which an equity ownership interest is maintained and for which the equity method of accounting is used, due to the ability to exert significant influence over decisions relating to their operating and financial affairs.

The following table summarizes information regarding Equity income, net of tax (dollars in millions):



	Three Months Ended					Six Months Ended

Total equity income, net of tax	$	429	$	300		$	984	$	723

Sales and income of our China JVs are not consolidated into our financial statements; rather, our proportionate share of the earnings of each joint venture is reflected as Equity income, net of tax. There have been no significant ownership changes in our China JVs since December 31, 2012.

We received dividends from nonconsolidated affiliates of $1.5 billion and $1.3 billion in the three months ended June 30, 2013 and 2012 and $1.6 billion and $1.4 billion in the six months ended June 30, 2013 and 2012. At June 30, 2013 and December 31, 2012 we had undistributed earnings including dividends declared but not received of $1.1 billion and $1.7 billion related to our nonconsolidated affiliates.

Transactions with Nonconsolidated Affiliates

Nonconsolidated affiliates are involved in various aspects of the development, production and marketing of cars, trucks and automobile parts. We purchase component parts and vehicles from certain nonconsolidated affiliates for resale to dealers. We also sell component parts and vehicles to certain nonconsolidated affiliates.

(a)	Refer to Note 3 for additional information concerning the acquisition of certain Ally Financial international operations.

In the three months ended June 30 and March 31, 2013 and 2012 we performed event-driven goodwill impairment tests for our GM Korea Company (GM Korea) reporting unit as the fair value of GM Korea continues to be below its carrying amount 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 of deterioration in the business outlook for GME that resulted in a reduction in the fair value of certain tax attributes and an increase in the fair value of estimated employee benefit obligations at March 31, 2012, we recorded a Goodwill impairment charge of $590 million, after which GME's Goodwill balance was $0.

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, which utilized Level 3 measures, about the extent and timing of future cash flows, growth rates, market share and discount rates that represent unobservable inputs into our valuation methodologies. 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.

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 June 30, 2013 and December 31, 2012: (1) Total assets of these VIEs were $538 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 $367 million and $254 million, which were composed of Accounts payable (principally trade) and Accrued liabilities. In the three months ended June 30, 2013 and 2012 Total net sales and revenue recorded by these VIEs were $250 million and $226 million and Net income was $17 million and $10 million. In the six months ended June 30, 2013 and 2012

Total net sales and revenue recorded by these VIEs were $496 million and $462 million and Net income was $37 million and $7 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 combined creditors of GM Korea's and HKJV's short-term debt of $244 million and $228 million, current derivative liabilities of $0 and $18 million and long-term debt of $23 million and $122 million at June 30, 2013 and December 31, 2012 do not have recourse to our general credit.

Automotive Financing - GM Financial

GM Financial uses special purpose entities (SPEs) that are considered VIEs to issue variable funding notes to third party bank-sponsored warehouse facilities and that issue asset-backed securities to investors in securitization transactions. The debt issued by these VIEs is backed by the cash flows related to finance receivables and leasing related assets transferred by GM Financial to the VIEs (Securitized Assets). GM Financial holds variable interests in the VIEs that could potentially be significant to the VIEs. GM Financial determined that they are the primary beneficiary of the SPEs because (1) the servicing responsibilities for the Securitized Assets give them the power to direct the activities that most significantly impact the performance of the VIEs and (2) the variable interests in the VIEs give them the obligation to absorb losses and the right to receive residual returns that could potentially be significant. The assets and liabilities of the VIEs are included in GM Financial's condensed consolidated balance sheets. The amounts are stated prior to intercompany eliminations.

The following table summarizes the assets and liabilities related to GM Financial's consolidated VIEs (dollars in millions):



	June 30, 2013		December 31, 2012
Restricted cash	$	1,397	$	744
Securitized assets	$	20,227	$	10,442
Securitization notes payable and other credit facilities	$	17,071	$	9,378

Restricted cash represents collections from the underlying securitized assets and certain reserve accounts held as credit enhancement for securitizations held by GM Financial for the benefit of the noteholders. Except for the acquisition accounting adjustments, GM Financial recognizes finance charge income, leased vehicle income and other income on the Securitized Assets and interest expense on the secured debt issued by the SPEs. GM Financial also maintains an allowance for credit losses on the Securitized Assets. Cash pledged to support the secured borrowings is deposited to a restricted cash account and recorded as restricted cash, which is invested in highly liquid securities with original maturities of 90 days or less.

The assets of the VIEs and the restricted cash held by GM Financial serve as the sole source of repayment for the asset-backed securities issued by these entities. Investors in the notes issued by the VIEs do not have recourse to GM Financial or their other assets, with the exception of customary representation and warranty repurchase provisions and indemnities that GM Financial provides as the servicer. GM Financial is not required and does not currently intend to provide additional financial support to these SPEs. While these subsidiaries are included in our condensed consolidated financial statements, these subsidiaries are separate legal entities and their assets are legally owned by them and are not available to GM Financial's creditors.

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 June 30, 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 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.

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 carrying amount of the related assets at June 30, 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.

Carrying amount	$	3,962	$	5,172
Fair value(a)	$	3,607	$	5,298

________


(a)	The fair value of debt included $2.4 billion and $4.1 billion measured utilizing Level 2 inputs at June 30, 2013 and December 31, 2012. The fair value of debt included $1.2 billion measured utilizing Level 3 inputs at June 30, 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.

Wholesale Financing

Wholesale financing represents arrangements, primarily with Ally Financial, where cash is received in advance of the final sale of vehicles, parts and accessories to our dealers or ultimate customer. These obligations typically settle through the sale and delivery of our products and generally do not require cash outflows to settle. Following the acquisition of Ally Financial's international operations in April 2013, most of the wholesale financing balance classified as debt became intercompany debt and was eliminated in consolidation, resulting in a decrease to our automotive debt balance of $682 million.

Losses on Extinguishment of Debt

In April 2013 GM Korea made a payment of $708 million to acquire, prior to the mandatory redemption date, the remaining balance of GM Korea's mandatorily redeemable preferred shares that had a carrying amount of $468 million. We recorded the difference of $240 million as a loss on extinguishment of debt.

In the six months ended June 30, 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.

________

(a)

For revolving credit facilities with variable interest rates and maturities of one year or less, the carrying amount is considered to be a reasonable estimate of fair value. The fair value of other secured debt and the unsecured debt is based on quoted market prices, when available. If quoted market prices are not available, the market value is estimated by discounting future net cash flows expected to be paid using current risk-adjusted rates.

(b)

Includes a private securitization that GM Financial used observable and unobservable inputs to estimate fair value. 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.

Secured Debt

The revolving credit facilities have revolving periods ranging from one to three years. At the end of the revolving period, if the facilities are not renewed, the debt will amortize over periods ranging from one to five years. Most of the secured debt was issued by VIEs. Refer to Note 10 for additional information relating to GM Financial's involvement with VIEs. These notes are repayable only from proceeds related to the underlying pledged finance receivables and leases. Weighted-average interest rates are both fixed and variable, ranging from 0.9% to 6.3% at June 30, 2013.

In the six months ended June 30, 2013 GM Financial entered into new credit facilities of $1.3 billion. In the six months ended June 30, 2013 GM Financial also issued securitization notes payable of $3.1 billion, with a weighted-average interest rate of 1.5% maturing on various dates through 2020. At June 30, 2013 revolving credit facilities of $4.4 billion and securitization notes payable of $2.0 billion resulted from the acquisition of Ally Financial international operations.

Unsecured Debt

The maturity dates of bank lines, which were assumed in the acquisition of Ally Financial's international operations, range up to three years. If not renewed, any balance outstanding under these bank lines is either immediately due in full or else will amortize over a defined period. Interest rates on bank lines and credit facilities ranged from 0.0% to 9.0% at June 30, 2013.

In May 2013 GM Financial issued and sold $2.5 billion in aggregate principal amount of senior notes due in 2016 through 2023 with interest rates that range from 2.8% to 4.3%. Senior notes outstanding at June 30, 2013 are due beginning in 2016 through 2023 and have interest rates that range from 2.8% to 6.8%.

Significant Plan Amendments, Benefit Modifications and Related Events

U.S. Salaried Defined Benefit Pension Plan

In January 2012 we amended the U.S. 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.

Canadian Salaried Defined Benefit Plans

In June 2012 we amended the Canadian salaried pension plan to cease the accrual of additional benefits effective December 31, 2012 and provide active employees a lump-sum distribution option at retirement. The remeasurement, amendments and offsetting curtailment increased the pension liability by $84 million. Active plan participants started receiving additional contributions in the defined contribution plan starting in January 2013.

We also amended the Canadian salaried retiree healthcare plan to eliminate post-65 healthcare benefits for employees retiring on or after July 1, 2014. In conjunction with this change we amended the plan to offer either a monthly monetary payment or an annual lump-sum cash payment to a defined contribution plan for health care in lieu of the benefit coverage provisions formerly provided under the healthcare plan. These amendments decreased the OPEB liability by $28 million.

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 8 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 June 30, 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. We are also required to post collateral to our counterparties. 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. 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.

At June 30, 2013 and December 31, 2012 no collateral was provided to counterparties; however, we have received collateral from counterparties related to certain derivative instruments. The potential effect from offsetting those derivative assets and liabilities that are subject to master netting agreements is insignificant.

Fair Value of Derivatives

Our policy is to present derivative assets and liabilities on a gross basis. The following table summarizes fair value measurements of our derivative instruments measured on a recurring basis (dollars in millions):



			Derivative Assets										Derivative Liabilities
	Notional		Current(a)		Non-Current(b)		Total		Level 2		Level 3		Current(c)		Non-Current(d)		Total		Level 2
June 30, 2013	$	9,129	$	70	$	51	$	121	$	56	$	65	$	10	$	1	$	11	$	11
December 31, 2012	$	10,751	$	144	$	22	$	166	$	129	$	37	$	26	$	1	$	27	$	27

________


(a)	Recorded in Other current assets.


(b)	Recorded in Other assets.


(c)	Recorded in Accrued liabilities.


(d)	Recorded in Other liabilities and deferred income taxes.

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 volume commitments, vehicle mix 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.

We had derivative instruments measured using Level 3 inputs with balances of $65 million and $56 million at June 30, 2013 and 2012, which included gains of $45 million and $34 million in the three and six months ended June 30, 2013, and losses of $49 million and $88 million in the three and six months ended June 30, 2012.

Gains (Losses) on Derivatives

The following table summarizes derivative gains (losses) recorded in Interest income and other non-operating income, net (dollars in millions):



	Three Months Ended					Six Months Ended

Total gains (losses) recorded in earnings	$	39	$	(41	)	$	14	$	(106	)

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 $4.7 billion and $775 million at June 30, 2013 and December 31, 2012. GM Financial had interest rate derivatives in liability positions with notional amounts of $4.8 billion and $775 million at June 30, 2013 and December 31, 2012. The fair value of these derivative financial instruments was insignificant.

In connection with the 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 currency exchange rates. At June 30, 2013 the foreign currency exchange swaps in asset and liability positions had notional amounts of $2.0 billion and $1.5 billion. The fair value of the foreign currency exchange swaps was insignificant. Refer to Note 3 for additional information on the acquisition.

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 2016 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.

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 Accounting Standards Codification (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 $600 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 June 30, 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 eight separate group actions in the Incheon District Court in Incheon, Korea. The cases, which in aggregate involve more than 10,000 employees, allege that GM Korea failed to include 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. GM Korea believes the decision of the Seoul High Court is incorrect and has appealed to the Supreme Court of the Republic of Korea and initiated a constitutional challenge to the adverse interpretation of the relevant statute. At June 30, 2013 we have an accrual of 811 billion South Korean Won (equivalent to $710 million) in connection with these cases. We do not believe we have any reasonably possible loss, as defined by ASC 450, “Contingencies”, in excess of the amount of the accrual. We are also party to litigation with current and former salary employees over allegations relating to Ordinary Wage regulation, although the issues differ due to differences between hourly and salaried benefit design. For those cases, we have identified a reasonably possible loss in excess of amounts accrued of 154 billion South Korean Won (equivalent to $135 million). 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-nine 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 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 is largely complete and final argument has been scheduled for October 9, 2013. 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 $887 million) which we believe represents a reasonable estimate of the approximate amount of the maximum reasonably possible loss.

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.

We have identified an emissions compliance issue with the Tavera produced in India. We have self-reported this issue to local government authorities and will cooperate with any review they may conduct. It is too early to determine the impact this issue will have on the Company or our Indian operations.

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.

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.

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 June 30, 2013 we estimate the remediation losses could range from $120 million to $240 million.

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 June 30, 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 $179 million and $186 million at June 30, 2013 and December 31, 2012 was pledged as collateral under the agreement. Through June 30, 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	6 Months Ended
Income Taxes	Jun. 30, 2013
Income Tax Expense (Benefit) [Abstract]
Income Taxes [Text Block]	Income Taxes For interim income tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. In the three months ended June 30, 2013 and 2012 income tax expense of $742 million and $241 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. In the six months ended June 30, 2013 and 2012 income tax expense of $1.2 billion and $457 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. The income tax expense increased in the three and six months ended June 30, 2013 due primarily to U.S. and Canada entities having full valuation allowances on deferred tax assets in 2012, which also caused the effective tax rate in the three and six months ended June 30, 2012 to be lower than the applicable statutory tax rate. We have open tax years from 2005 to 2012 with various significant tax jurisdictions. In April 2013 we settled a previously disclosed Mexican income tax matter covering the years 2002, 2003 and 2004 for $36 million.

- 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 tables summarize the reserves related to restructuring and other initiatives and charges by segment, including postemployment benefit reserves and charges (dollars in millions):

Three and Six Months Ended June 30, 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 August 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 June 30, 2013 the active separation programs related to Germany and the United Kingdom had a total cost of $93 million and had affected a total of 625 employees. We expect to complete these programs in 2013 and incur an additional $140 million, which will affect an additional 540 employees.

GMIO recorded charges, interest accretion and other and revisions to estimates for previously announced separation programs in Korea and Australia. Through June 30, 2013 the active separation programs related to Korea and Australia had a total cost of $48 million and had affected a total of 400 employees.

GMSA recorded charges for active separation programs. Through June 30, 2013 the active separation programs related to Brazil had a total cost of $92 million.

Three and Six Months Ended June 30, 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. Substantially all of the program cost was recorded in the three months ended March 31, 2012.

GME recorded charges, interest accretion and other and revisions to estimates primarily related to previously announced separation and early retirement programs in Germany. Through June 30, 2012 the separation programs had a total cost of $313 million and affected a total of 1,900 employees.

In the three months ended June 30, 2012 GMIO recorded charges and interest accretion and other for previously announced separation programs in Korea.

In the three months ended June 30, 2012 GMSA recorded charges for employee separation costs related to a separation program in Brazil.

Earnings Per Share

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 are outstanding.

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

________


(a)	Includes earned but undistributed dividends of $26 million on our Series A Preferred Stock and $20 million on our Series B Preferred Stock in the three and six months ended June 30, 2013 and 2012.

Our Series B Preferred Stock is a participating security and requires the application of the more dilutive of the two-class or if-converted method to calculate earnings per share when the applicable market value of our common stock is below or above the range of $33.00 to $39.60 per common share. We are required to use the if-converted method to calculate earnings per share when the applicable market value of our common stock is within this range. The applicable market value of our common stock is the average closing prices over the 40 consecutive trading day period ending on the third trading day immediately preceding the reporting period end date. Under the two-class method, 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, resulting in a lower basic and diluted earnings per share amount. The calculation of the applicable market value at the date of our financial statements will apply to the current quarter and the year to date periods presented, irrespective of the applicable market value computed during the prior quarters of the current year. Our calculation of earnings per share will vary from period to period depending on whether the two-class or if-converted method is required.

In the three and six months ended June 30, 2013 the applicable market value of our common stock was within the range of $33.00 to $39.60 per common share and, as such, we applied the if-converted method for purposes of calculating diluted earnings per share. The dilutive effect of the Series B Preferred Stock was determined by assuming conversion of the securities at the beginning of the period resulting in an increase to the weighted-average common shares outstanding and an increase to Net income attributable to common stockholders from adding the accumulated dividends on our Series B Preferred Stock. The impact on diluted earnings per share is an increase of $0.03 and $0.08 for the three and six months ended June 30, 2013 using the if-converted as compared to the two-class method. In the three and six months ended June 30, 2012 we were required to use the two-class method for calculating basic and diluted earnings per share because the applicable market value of our common stock was below $33.00 per common share.

In the three and six months ended June 30, 2013 and 2012 warrants to purchase 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.

Stock Incentive Plans

Long-Term Incentive Plan

We granted 7 million RSUs valued at the grant date fair value of our common stock in the six months ended June 30, 2013 and 2012. Substantially all of these awards vest over a three-year service period, as defined in the terms of each award. 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 non-Top 25 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 six months ended June 30, 2013 and 2012 a portion of each participant's salary accrued on each salary payment date converted to RSUs on a quarterly basis. In March 2012 we amended the plan to provide for cash settlement of awards and reclassified $97 million from Additional paid-in capital to Accrued liabilities and Other liabilities and deferred income taxes. Prior to this amendment it was our policy to issue new shares upon settlement of these awards. In June 2013 we amended the plan to provide for cash or share settlement of awards based on election by the participant. The liability for these awards continues to be remeasured to fair value at the end of each reporting period.

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	8.0		$	28.10
Settled	(14.6	)	$	20.55
Forfeited or expired	(0.6	)	$	26.53
RSUs outstanding at June 30, 2013	19.7		$	26.86	1.5

RSUs unvested and expected to vest at June 30, 2013	11.9		$	27.79	2.1
RSUs vested and payable at June 30, 2013	6.7		$	25.12	—

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



	Three Months Ended				Six Months Ended
	June 30, 2013		June 30, 2012		June 30, 2013		June 30, 2012
Compensation expense	$	77	$	55	$	141	$	127
Income tax benefit	$	25	$	—	$	45	$	—

At June 30, 2013 the total unrecognized compensation expense for nonvested equity awards was $262 million. This expense is expected to be recorded over a weighted-average period of 2.1 years.

The total fair value of RSUs that vested in the six months ended June 30, 2013 and 2012 was $239 million and $82 million.

In the six months ended June 30, 2013 total payments of $61 million were made to settle 2.2 million RSUs under stock incentive plans. Payments made in the six months ended June 30, 2012 were insignificant.

Segment Reporting [Abstract]

Segment Reporting [Text Block]

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. We record certain transactions between our automotive and finance segments as intersegment activity and eliminate them in consolidation. 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 June 30, 2013 we also had equity ownership stakes directly or indirectly in entities through various regional subsidiaries, primarily in Asia. These companies design, manufacture and market vehicles under the following brands:



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

All intersegment balances and transactions have been eliminated in consolidation.

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

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.
Recently Adopted Accounting Principles [Policy Text Block]	Recently Adopted Accounting Principles On January 1, 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 in financial statements; rather, it requires certain disclosures of the amount of reclassifications of items from other comprehensive income to net income by component. The related disclosures are presented in Note 19.

- 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.
