Basis of Presentation And Recent Accounting Standards

6 Months Ended

Basis Of Presentation

Basis of Presentation [Text Block]

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, 2011 (2011 Form 10-K) 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.

Change in Presentation of Financial Statements

In 2012 we changed the presentation of our condensed consolidated balance sheet, condensed consolidated statements of cash flows and certain notes to the condensed consolidated financial statements to classify the assets and liabilities of GM Financial as current or non-current and to combine line items which were either of a related nature or not individually material. We have made corresponding reclassifications to the comparable information for all periods presented.

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 introduced 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 of our Venezuelan subsidiaries at June 30, 2012 and December 31, 2011 were $636 million and $438 million. At June 30, 2012 and December 31, 2011 other consolidated entities have receivables from our Venezuelan subsidiaries of $540 million and $380 million. The total amounts pending government approval for settlement at June 30, 2012 and December 31, 2011 were BsF 3.2 billion (equivalent to $751 million) and BsF 2.3 billion (equivalent to $535 million), for which some requests have been pending from 2007.

Significant Non-Cash Activity

Investing Cash Flows

The following table summarizes the amounts of non-cash property additions that have been excluded from Expenditures for property within the investing activities section of the condensed consolidated statements of cash flows because no cash has been expended (dollars in millions):



	Six Months Ended
	June 30, 2012		June 30, 2011
Non-cash property additions	$	3,737	$	2,989

Recently Adopted Accounting Principles

In 2012 we adopted the provisions of Accounting Standards Update (ASU) 2011-05, “Presentation of Comprehensive Income” (ASU 2011-05) that requires presentation of all non-owner changes in equity in one continuous statement of comprehensive income or in two separate but consecutive statements. We elected to provide a separate statement of comprehensive income for all periods presented. The amendments in this update do not change the items that must be reported in other comprehensive income (OCI) or when an OCI item must be reclassified to net income. The adoption of ASU 2011-05 did not affect our condensed consolidated statements of financial position, results of operations and cash flows.

ASU 2011-05 was modified in December 2011 by the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” This update indefinitely defers certain provisions of ASU 2011-05 that require the disclosure of the amount of reclassifications of items from OCI to net income by component of net income and by component of OCI.

Acquisition And Disposals Of Businesses [Abstract]

Acquisition And Disposals Of Businesses

Acquisition of Businesses

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. The following table summarizes the amounts recorded in connection with the acquisition of GMAC Venezuela, which are included in our GMSA segment (dollars in millions):



	March 1, 2012
Cash	$	79
Other assets	11
Liabilities	(11		)
Bargain purchase gain	(50		)
Consideration paid	$	29

We determined the excess of net assets acquired over consideration paid was attributable to the measurement differences between the BsF denominated assets and liabilities valued using the official foreign exchange rate, as required by U.S. GAAP, and the enterprise value which has been discounted to reflect the uncertainty surrounding our ability to convert the BsF to U.S. Dollars and the risks of operating in a politically unstable country. The measurement differences do not qualify to be recorded in the application of the acquisition method of accounting, and we recorded the excess of net assets acquired over the consideration paid as a bargain purchase gain. The bargain purchase gain was recorded in Interest income and other non-operating income, net. We did not provide pro forma financial information because we do not believe the information is material.

Acquisition of Additional GM Korea Interests

In March 2011 we completed the acquisition of an additional 6.9% interest in GM Korea Company (GM Korea) for cash of $100 million. The transaction was accounted for as an equity transaction as we retain the controlling financial interest in GM Korea. This transaction reduced our equity attributable to Noncontrolling interests by $134 million and our Accumulated other comprehensive income by $7 million and increased our Capital surplus by $41 million. We now own 77.0% of the outstanding shares of GM Korea.

- 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.

At June 30, 2012 the carrying amount of our investment in Peugeot S.A. (PSA) exceeded its fair value. The share prices for comparable European automotive companies are currently experiencing significant volatility stemming, in part, from the eurozone debt crisis and its effect on automotive sales within the eurozone, as well as the uncertainty around future sales. We assessed whether the decline in value represented an other-than-temporary impairment and concluded that the impairment is temporary. We believe that the recent economic uncertainty is weighing heavily on the valuation of PSA. Should market conditions not recover in the near-term, we may conclude the impairment is other-than-temporary, resulting in an impairment charge. We currently have the ability and intent to hold the investment until its fair value recovers.

________

(a) Includes finance receivables and loans originated of $174 million and principal collections of $46 million in connection with the commercial lending program for the three and six months ended June 30, 2012.

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



	June 30, 2012				December 31, 2011
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
GM Financial finance receivables, net	$	10,030	$	10,330	$	9,162	$	9,386

GM Financial determined the fair value of consumer finance receivables using Level 2 and 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 are 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 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 our cash flow model.

Substantially all commercial finance receivables have variable interest rates and maturities of one year. Therefore, carrying amount is considered to be a reasonable estimate of fair value which is determined using Level 1 inputs.

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 June 30, 2012 and December 31, 2011 the accrual of finance charge income has been suspended on delinquent consumer finance receivables based on contractual amounts due of $412 million and $439 million. At June 30, 2012 there were no commercial finance receivables or loans on non-accrual status.

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 six months ended June 30, 2012 as a result of improvements in credit performance of the pre-acquisition portfolio, which resulted in an increase of expected cash flows of $170 million, GM Financial transferred this excess non-accretable discount to accretable yield. GM Financial will recognize this excess as finance charge income over the remaining life of the portfolio.

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



	Three Months Ended						Six Months Ended

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 and gain on disposal of investments.

SGM is a joint venture established in 1997 by Shanghai Automotive Industry Corporation (SAIC) (51%) and us (49%). SGM has interests in three other joint ventures in China: SGM Norsom, SGM DY and SGM DYPT. These three joint ventures are jointly held by SGM (50%), SAIC (25%) and us (25%). These four joint ventures are engaged in the production, import, and sale of a comprehensive range of products under the brands of Buick, Chevrolet and Cadillac. SGM also has interests in Shanghai OnStar (20%) and Shanghai Chengxin Used Car (33%).

SGMS is a joint venture established in November 2011 by SAIC (51%) and us (49%) to engage in the sales of the imported brands of Buick, Chevrolet and Cadillac and the sales of automobiles manufactured by SGM.

Sale of New Delphi

In March 2011 we sold our Class A Membership Interests in Delphi Automotive LLP (New Delphi) to New Delphi for $3.8 billion. The Class A Membership Interests sold represented 100% of our direct and indirect interests in New Delphi and 100% of New Delphi's Class A Membership Interests issued and outstanding. The sale terminated any direct and indirect obligation to loan New Delphi up to $500 million under a term loan facility established in October 2009 when New Delphi was created and the Class A Membership Interests were issued. New Delphi had not borrowed under this loan facility. In March 2011 we recorded a gain of $1.6 billion related to the sale in Equity income, net of tax and gain on disposal of investments. Our existing supply contracts with New Delphi were not affected by this transaction.

Investment in HKJV

In March 2011 the fair value of our investment in SAIC GM Investment Limited (HKJV) was determined to be less than its carrying amount. HKJV is our joint venture which controls our automotive operations in India. The loss in value was determined to be other-than-temporary; therefore, we recorded an impairment charge of $39 million in the three months ended March 31, 2011. In addition we recorded other charges totaling $67 million related to our investment in the HKJV.

We have provided SAIC Motor Hong Kong Investment Limited (SAIC-HK), a 50% equity holder in HKJV, an option to not participate in future capital injections, which would otherwise be required under certain circumstances. Upon election to exercise the option SAIC-HK would be relieved from providing up to $173 million in future capital injections. The related option liability was $94 million and $88 million and total unrealized losses were $70 million and $64 million at June 30, 2012 and December 31, 2011.

A Monte Carlo option-pricing model was used to estimate the fair value of the option liability which is a Level 3 measure. The key inputs into the option pricing model were the expected volatility, risk-free rate, expected term, fair value of HKJV and expected amounts of the future funding requirement. The fair value estimate of the option is most sensitive to the fair value of HKJV, which is unobservable. A discounted cash flow methodology was utilized to estimate the fair value of HKJV. A decrease in the fair value of HKJV will result in an increase in the fair value of the option liability.

We were informed of SAIC-HK's intent to exercise its right to not participate in future capital injections in HKJV. If this occurs we plan to settle the promissory note in the three months ending September 30, 2012 and provide an additional equity investment of $125 million into HKJV. As a result SAIC-HK's interest in HKJV would be diluted from 50% to 9%. We also anticipate that the shareholders agreement would be amended such that we obtain control of and consolidate HKJV.

VMM Deconsolidation

In June 2011 we entered into a new shareholder agreement with Fiat Powertrain Technologies SPA related to VM Motori (VMM) in Italy. Prior to the new shareholder agreement, we controlled VMM and consolidated VMM’s assets, liabilities and results of operations. Under the new shareholder agreement, we retain 50% ownership but no longer have control. Accordingly, we removed the assets and liabilities of VMM, which included allocated goodwill of $36 million from our GME reporting unit, from our consolidated financial statements and recorded an equity interest in the amount of $46 million.

We adopted the provisions of ASU 2010-28 "When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts" (ASU 2010-28) on January 1, 2011 and performed Step 2 of the goodwill impairment testing analysis for our GME reporting unit which had a negative carrying amount resulting in the recognition of a cumulative-effect adjustment to Retained earnings. GME continued to have a negative carrying amount and because it was more likely than not further goodwill impairment existed in the three months ended March 31, 2012 and 2011 we recorded further Goodwill impairment charges in the three months ended March 31, 2012 and 2011. At March 31, 2012 GME's Goodwill balance was $0.

In the three months ended March 31 and June 30, 2012 we performed event-driven goodwill impairment tests at our GM Korea reporting unit, which resulted in a Goodwill impairment charge of $27 million in the three months ended March 31, 2012 within our GMIO segment.

_________


(a)	Impairment charges were recorded as a cumulative-effect adjustment to beginning Retained earnings upon the adoption of ASU 2010-28 in the three months ended March 31, 2011.

The Goodwill impairment charges recorded as a result of the initial adoption of ASU 2010-28 in the three months ended March 31, 2011 and the event-driven goodwill impairment tests in the six months ended June 30, 2012 and 2011 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, as discussed in Note 32 to our consolidated financial statements in our 2011 Form 10-K. The net decreases resulted primarily from a decrease in our nonperformance risk and an improvement in our incremental borrowing rates since July 10, 2009. At certain of the testing dates the net decrease also resulted from an increase in the high quality corporate bond rates utilized to measure our employee benefit obligations and a decrease in credit spreads between high quality corporate bond rates and market interest rates for companies with similar nonperformance risk. 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.

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. Assumptions used in our discounted cash flow analysis that have the most significant effect on the estimated fair values of our reporting units include:

•Our estimated WACC;

•Our estimated long-term growth rates; and

•Our estimate of industry sales and our market share.

The valuation methodologies utilized to perform our goodwill impairment testing were consistent with those used in our application of fresh-start reporting on July 10, 2009 and in subsequent annual or event-driven goodwill impairment tests and utilized Level 3 measures. Because the fair value of goodwill can be measured only as a residual amount and cannot be determined directly we calculated the implied goodwill for GME and GM Korea in the same manner that goodwill is recognized in a business combination pursuant to Accounting Standards Codification (ASC) 805, "Business Combinations."

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)(b)		Market Share(a)(b)
	Goodwill(c)		WACC		Long-Term Growth Rates		2011/2012	2015/2016	2011/2012		2015/2016
GME - At January 1, 2011	$	3,053	17.0	%	0.5	%	18.4	22.0	6.6	%	7.4	%
GME - At March 31, 2011	$	1,661	16.5	%	0.5	%	18.4	22.0	6.6	%	7.4	%

GM Korea - At March 31, 2012	$	564	14.8	%	3.0	%	81.0	97.1	1.4	%	1.1	%
GM Korea - At June 30, 2012	$	523	14.8	%	3.0	%	81.0	97.1	1.4	%	1.1	%

_________


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


(b)	GME amounts at January 1, 2011 and March 31, 2011 are 2011 through 2015 and GME amounts at March 31, 2012 are 2012 through 2016. GM Korea amounts are 2012 through 2015.


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

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 sales 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.

During our Step 2 analyses we determined the fair values of these reporting units had not increased sufficiently to give rise to implied goodwill other than the goodwill arising from 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. On our testing dates our Step 2 analyses indicated GME's and GM Korea's implied goodwill was less than their recorded goodwill; therefore, Goodwill was adjusted at the various dates indicated in the table above, except for at June 30, 2012 GM Korea's implied goodwill exceeded its recorded goodwill. As such GM Korea's goodwill was not adjusted at June 30, 2012.

Future goodwill impairments that may be material could be recognized should the economic uncertainty continue, our equity price decline on a sustained basis, global economies enter into another recession and industry growth stagnates, or should we reverse deferred tax asset valuation allowances in certain tax jurisdictions. Our U.S. and Canadian operations are experiencing current profitability. To the extent this profitability trend continues our conclusion regarding the need for full valuation allowances could change leading to the reversal of a significant portion of valuation allowance in 2012. This could result in a material impairment of goodwill.

In these circumstances future goodwill impairments would largely be affected by decreases in the fair value-to-U.S. GAAP differences that have occurred subsequent to our application of fresh-start reporting. The decrease may occur upon: (1) an improvement in our credit rating; (2) a decrease in credit spreads between high quality corporate bond rates and market interest rates thus resulting in a decrease in the spread between our employee benefit related obligations under U.S. GAAP and their fair values; and/or (3) a change in the fair values of our estimated employee benefit obligations. A decrease would also occur upon reversal of our deferred tax asset valuation allowances. Any decreases in the fair value-to-U.S. GAAP differences that result in goodwill impairment would have a negative effect on our earnings that could be material.

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.

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, 2012 and December 31, 2011: (1) Total assets of these VIEs were $446 million and $463 million, which were composed of Cash and cash equivalents, Accounts and notes receivable, net, Inventories and Property, net; and (2) Total liabilities were $267 million and $298 million, which were composed of Accounts payable (principally trade) and Accrued liabilities. In the three months ended June 30, 2012 and 2011 Total net sales and revenue recorded by these VIEs were $226 million and $227 million and Net income was $10 million and $21 million. In the six months ended June 30, 2012 and 2011 Total net sales and revenue recorded by these VIEs were $462 million and $337 million and Net income was $7 million and $25 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, a non-wholly owned consolidated subsidiary that we control through a majority voting interest, is also a VIE because in the future it may require additional subordinated financial support. At June 30, 2012 and December 31, 2011 the creditors of GM Korea's short-term debt of $116 million and $171 million, current derivative liabilities of $31 million and $44 million and long-term debt of $4 million and $7 million do not have recourse to our general credit. In February 2011 we provided a guarantee to a minority shareholder in GM Korea to repurchase GM Korea's preferred shares according to the redemption schedule should GM Korea not repurchase the shares. This guarantee decreased the amount of long-term debt which did not have recourse to our general credit in the three months ended March 31, 2011.

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 Ally Financial and HKJV. 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, excluding Ally Financial that is disclosed in Note 22 (dollars in millions):

(a)	The carrying amount of the related assets at June 30, 2012 and 2011 may no longer equal the fair value as the fair value presented is as of the date the impairment was taken 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.

Carrying amount	$	5,143	$	5,295
Fair value(a)	$	5,649	$	5,467

__________


(a)	The fair value of debt included $4.4 billion measured utilizing Level 2 inputs at June 30, 2012 and December 31, 2011. The fair value of debt included $1.2 billion and $1.1 billion measured utilizing Level 3 inputs at June 30, 2012 and December 31, 2011.

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 forward 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.

In the three months ended March 31, 2012 we prepaid and retired a debt obligation of $39 million with a carrying amount of $21 million and we recorded a loss on extinguishment of debt of $18 million which primarily represented the unamortized debt discount.

The fair value of the bank funding facility, securitization notes payable and senior notes and convertible 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 of the medium-term note facility. Observable inputs are used regarding an advance rate on the receivables to generate an estimated debt amount as well as the interest rate used to calculate the series of estimated principal payments. Those series of interest payments are discounted using an unobservable interest rate based on the most recent securitization in order to estimate fair value which would approximate the replacement value.

GM Financial uses observable and unobservable inputs to estimate fair value for the private securitization 2012 - PPI. 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.

Pensions and Other Postretirement Benefits

Contributions

We made a contribution in January 2011 to our U.S. hourly and salaried defined benefit pension plans of 61 million shares of our common stock valued at $2.2 billion for funding purposes at the time of contribution. The contributed shares qualified as a plan asset for funding purposes at the time of contribution and as a plan asset valued at $1.9 billion for accounting purposes in July 2011. This was a voluntary contribution above our funding requirements for the pension plans.

We continue to pursue various options to fund and derisk our pension plans, including continued changes to the pension asset portfolio mix to reduce funded status volatility.

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 liability and decreased the net actuarial loss component of Accumulated other comprehensive income by $309 million. Active plan participants will receive additional contributions in the defined contribution plan starting in October 2012.

In May 2012 we entered into an agreement in which the salaried pension plan will purchase a group annuity contract from an insurance company that requires the insurance company to pay and administer the future annuity payments to certain of our salaried retirees. Following the execution of the agreement certain retired participants in the salaried plan are being offered lump-sum distributions. Approximately 42,000 salaried retirees and surviving beneficiaries will be eligible to receive a voluntary single lump-sum payment option. Retired salaried employees that are not offered lump-sum distributions or those that decline the lump-sum offer will receive annuity payments from the insurance company in accordance with the terms of the group annuity contract. Approximately 118,000 salaried retirees are affected by changes depending on retirement date and eligibility. We will provide additional funding to the salaried pension plan so that the plan has sufficient assets to purchase the group annuity contract, provide additional funding to the salaried pension plan for current salaried employees and complete the transactions contemplated by the agreement. It is expected that the additional funding for the salaried pension plan will be in the range of $3.5 billion to $4.5 billion. Due to the magnitude of the pension obligations being settled and the interest rate sensitivity of the transactions, it is possible that the ultimate amount of additional funding could be outside this range when the transactions are completed. The ultimate amount of funding will be subject to several additional factors including plan asset returns, the lump-sum election rate and those associated with the creation of the new defined benefit plan. Certain aspects of the transactions contemplated by the agreement are subject to external regulatory review. Assuming all of the closing conditions are met we expect the transactions contemplated under the agreement to be completed by December 31, 2012.

In August 2012, the U.S. salaried pension plan was amended to create a legally separate new defined benefit pension plan for primarily active and terminated vested participants. The underlying benefits offered to plan participants were unchanged. The existing plan will primarily cover retirees receiving payments. We expect to settle the existing plan by December 31, 2012 through lump-sum distributions and the purchase of a group annuity contract from an insurance company, as previously discussed, and the plan will subsequently be terminated. Accordingly, we will remeasure the U.S. salaried pension plan in August 2012.

Canadian Salaried Benefit Plans

In June 2012 we amended the Canadian salaried pension plan to cease the accrual of additional benefits effective January 1, 2013 and provide active employees a lump-sum distribution option at retirement. The remeasurement, amendments and offsetting curtailment increased the liability by $84 million, and resulted in a net decrease in the pre-tax components of Accumulated other comprehensive income composed of net actuarial loss of $58 million, net actuarial curtailment gain of $20 million and prior service cost of $46 million. Active plan participants will receive 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 liability by $28 million and resulted in a net increase in the pre-tax components of Accumulated other comprehensive income composed of prior service credit of $51 million and net actuarial loss of $23 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 Pensions and a pre-tax increase in the net actuarial loss component of Accumulated other comprehensive income.

In the three months ended March 31, 2011 certain pension plans in GME were remeasured as part of our Goodwill impairment testing, resulting in a decrease of $272 million in Pensions and a pre-tax increase in the net actuarial gain component of Accumulated other comprehensive income.

Derivative Financial Instruments and Risk Management

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, 2012 our derivative instruments consisted primarily of forward contracts and options. At June 30, 2012 and December 31, 2011 no outstanding derivative contracts 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. Certain of our agreements with counterparties require that we provide cash collateral. At June 30, 2012 and December 31, 2011 no collateral was posted related to derivative instruments, and we did not have any agreements with counterparties to derivative instruments containing 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.

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 entered into a power plant lease agreement which included the purchase of natural gas at a fixed price adjusted for movements in heavy fuel oil and coal indices as published by a German governmental agency. The natural gas agreement was determined to be a derivative for accounting purposes and is valued as a forward contract. This commodity derivative valuation uses Level 3 inputs. The significant unobservable inputs used in the fair value measurement of our commodity derivative are coal and heavy fuel oil forward rates and supplier credit spreads. Significant increases (decreases) in the coal and heavy fuel oil index and supplier credit spread would result in significant decreases (increases) to the fair value measurement.

We are party to a long-term supply agreement which provides for pricing to be partially denominated in a currency other than the functional currency of the parties to the contract. This pricing feature was determined to be an embedded derivative which we have bifurcated for valuation and accounting purposes. This embedded derivative is valued using an industry accepted model which contains Level 3 inputs.

The significant unobservable inputs used in the fair value measurement of our embedded foreign currency derivative is the estimate of the Turkish central bank's Euro/Turkish Lira (TRY) forward exchange rate and monthly volume commitment and vehicle mix. Significant decreases (increases) to Euro/TRY forward exchange rate and monthly volume commitment and vehicle mix would result in significant decreases (increases) to the fair value measurement.

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 significant quantitative unobservable inputs and assumptions used in the fair value measurement of the derivatives at June 30, 2012:



	Valuation Technique	Significant Unobservable Input	Metric
Commodity	Discounted cash flow	Coal forward price per ton in Euro(a)	€110.44
		Heavy fuel oil forward price per ton in Euro(a)	€528.56
		Supplier nonperformance risk (average)	2.72%
Embedded	Discounted cash flow	Average Euro/TRY forward exchange rate(b)	€2.75
		Volume commitment and vehicle mix in Euro(c)	€1.0 billion

__________


(a)	Forward prices are estimated to be equivalents of the spot price as published by a governmental agency.


(b)	Calculated by adjusting market forward rates for the spread between current market and Turkish central bank spot prices.


(c)	Volume commitment is spread evenly on a monthly basis and vehicle mix is pursuant to management forecasts.

In February 2011 we exercised warrants to purchase 4 million shares of a supplier's common stock at $2.76 per share and sold the shares and received proceeds of $48 million.

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 swaps and caps in asset positions with notional amounts of $1.5 billion and $2.0 billion at June 30, 2012 and December 31, 2011. GM Financial had interest rate swaps and caps in liability positions with notional amounts of $1.5 billion and $2.0 billion at June 30, 2012 and December 31, 2011. The fair value of these derivative financial instruments was insignificant.

Guarantees

We have provided guarantees related to the residual value of certain operating leases. These guarantees terminate in years ranging from 2016 to 2035. Certain leases contain renewal options.

We provide payment guarantees on commercial loans made by Ally Financial and outstanding with certain third parties, such as dealers or rental car companies. These guarantees either expire in 2012 through 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. Refer to Note 22 for additional information on guarantees that we provide to Ally Financial.

We have agreements with third parties that guarantee the fulfillment of certain suppliers' commitments and other obligations. These guarantees expire in 2012 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. At June 30, 2012 any proceeds from collateral would be approximately $50 million.

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 June 30, 2012 we estimate the remediation losses could range from $130 million to $290 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 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 indirect tax-related matters as well as various non-U.S. labor-related 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. The various non-U.S. labor-related matters include claims from current and former employees related to alleged unpaid wage, benefit, severance, and other compensation matters. Certain South American administrative proceedings are indirect tax-related and may require that we deposit funds in escrow. Escrow deposits may range from $458 million to $687 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, 2012. 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.

Commencing on or about September 29, 2010, current and former hourly employees of GM Korea filed six separate group actions in the Incheon District Court in Incheon, Korea. The cases 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. Although GM Korea intends to vigorously defend the claims asserted, at June 30, 2012 we have an accrual of 175 billion Korean Won (equivalent to $152 million) in connection with these cases. The current estimate of the value of plaintiffs' claims, if allowed in full, exceeds the accrual by 642 billion Korean Won (equivalent to $556 million) which represents the reasonably possible liability exposure. 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.

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. 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.

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 (New VEBA). 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, but we believe that the claim is without merit and we have no accrual relating to this litigation. We filed a motion in the U.S. Bankruptcy Court for the Southern District of New York (Bankruptcy Court) asserting that the UAW's claim is barred by the Bankruptcy Court approved 2009 UAW Retiree Settlement Agreement and by other orders issued by the Bankruptcy Court that preclude additional GM contributions to the New VEBA. 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. On August 23, 2011, the Bankruptcy Court issued an opinion abstaining from hearing the case, which will accordingly be litigated in the U.S. District Court for the Eastern District of Michigan.

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 (GBP), which were guaranteed by Old GM (Guaranty) (collectively, the Notes). The proceeds of the 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 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 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 Trustee. The matter is currently scheduled for trial commencing on August 7, 2012.

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 $918 million) which we believe represents a reasonable estimate of the approximate amount of the maximum reasonably possible loss.

Liability Related to Contingently Issuable Shares

Under the Amended and Restated Master Sale and Purchase Agreement, as amended between us and Old GM and certain of its direct and indirect subsidiaries, we were obligated to issue additional shares of our common stock to MLC (Adjustment Shares) in the event that allowed general unsecured claims against MLC, as estimated by the Bankruptcy Court, exceed $35.0 billion. Following the dissolution of MLC on December 15, 2011, any Adjustment Shares we are obligated to issue will be issuable to the GUC Trust. The maximum number of Adjustment Shares issuable is 30 million shares (subject to adjustment to take into account stock dividends, stock splits and other transactions). The number of Adjustment Shares to be issued is calculated based on the extent to which estimated general unsecured claims exceed $35.0 billion with the maximum number of Adjustment Shares issued if estimated general unsecured claims total $42.0 billion or more. At June 30, 2012, based on the most recent information available, we concluded that the possibility that general unsecured claims would exceed $35.0 billion was remote. We do not anticipate future disclosure regarding Adjustment Shares.

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 $197 million and $209 million at June 30, 2012 and December 31, 2011 was pledged as collateral under the agreement. Through June 30, 2012 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, 2012
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 effect 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 June 30, 2012 income tax expense of $241 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. The recorded effective tax rate is lower than the applicable statutory tax rate due primarily to income earned in jurisdictions for which a full valuation allowance is recorded. In the three months ended June 30, 2011 the income tax benefit of $61 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation more than offset by tax benefit attributable to previously unrecognized tax benefits in various jurisdictions. This benefit includes reductions in interest expense and valuation allowances associated with these previously unrecognized tax benefits. In the six months ended June 30, 2012 income tax expense of $457 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. The recorded effective tax rate is lower than the applicable statutory tax rate due primarily to income earned in jurisdictions for which a full valuation allowance is recorded. In the six months ended June 30, 2011 income tax expense of $76 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation partially offset by tax benefits attributable to previously unrecognized tax benefits in various jurisdictions. We file income tax returns in multiple jurisdictions and are subject to examination by taxing authorities throughout the world. We have open tax years from 2002 to 2011 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 March 2012 a Mexican income tax audit covering the 2004 tax year was concluded and an assessment, adjusted for inflation, of $128 million including tax, interest and penalties was issued. The total 2002, 2003 and 2004 assessments, adjusted for inflation, as of June 30, 2012 including tax, interest and penalties is $292 million. We believe we have adequate reserves established. Collection of any assessment will be suspended until a revised assessment is issued and during any subsequent proceedings through U.S. and Mexican competent authorities. In May 2012 a Brazilian income tax assessment was issued related to the 2007 tax year totaling $180 million including tax, interest and penalties. We believe we have adequate reserves established. Proceedings may require that we deposit escrow funds in the future. At June 30, 2012 it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits in the next 12 months.

Restructuring and Related Activities [Abstract]

Restructuring And Other Initiatives

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. 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 (excluding restructuring reserves related to dealer wind-down agreements) and charges by segment, including postemployment benefit reserves and charges (dollars in millions):

(a)	The remaining cash payments related to these reserves for restructuring and other initiatives, including temporary layoff benefits of $363 million and $369 million at June 30, 2012 and June 30, 2011 for GMNA, primarily relate to postemployment benefits.

Three and Six Months Ended June 30, 2012

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.

Our 2011 UAW labor agreement 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 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. We expect to complete these programs in 2013 and incur an additional $0.1 billion, which will affect an additional 350 employees. To the extent these programs involve voluntary separations, no liabilities are recorded until offers to employees are accepted. If employees are involuntarily terminated, a liability is recorded at the communication date.

In the three months ended June 30, 2012 GMIO recorded charges of $22 million for employee separation costs related to a voluntary separation program in Korea which affected 146 employees. A liability under this program is recorded as offers to employees are accepted.

In the three months ended June 30, 2012 GMSA recorded charges of $71 million for employee separation costs related to a separation program in Brazil. We may incur additional future charges in connection with this program.

Three and Six Months Ended June 30, 2011

GMNA recorded charges, interest accretion and other and revisions to estimates that increased the reserves primarily related to skilled trades U.S. hourly employees who participated in a special attrition program.

GME recorded charges and interest accretion and other for separation programs primarily related to previously announced programs in Germany.

Dealer Wind-downs

We market vehicles worldwide through a network of independent retail dealers and distributors. We determined that a reduction in the number of GMNA dealerships was necessary.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings Per Share

In the three and six months ended June 30, 2012 and 2011 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 June 30, 2012 and 2011. 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 tables summarize basic and dilutive 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, 2012 and 2011.

(b)

Includes cumulative dividends on preferred stock of $214 million and earnings of $145 million that have been allocated to the Series B Preferred Stock holders in the three months ended June 30, 2012 and cumulative dividends on preferred stock of $214 million and earnings of $254 million that have been allocated to the Series B Preferred Stock holders in the three months ended June 30, 2011. Includes cumulative dividends on preferred stock of $429 million and earnings of $241 million that have been allocated to the Series B Preferred Stock holders in the six months ended June 30, 2012 and cumulative dividends on preferred stock of $429 million and earnings of $542 million allocated to the Series B Preferred Stock holders in the six months ended June 30, 2011.

(c)

Includes cumulative dividends on preferred stock of $214 million and earnings of $136 million that have been allocated to the Series B Preferred Stock holders in the three months ended June 30, 2012 and cumulative dividends on preferred stock of $214 million and earnings of $233 million that have been allocated to the Series B Preferred Stock holders in the three months ended June 30, 2011. Includes cumulative dividends on preferred stock of $429 million and earnings of $226 million that have been allocated to the Series B Preferred Stock holders in the six months ended June 30, 2012 and cumulative dividends on preferred stock of $429 million and earnings of $495 million that have been allocated to the Series B Preferred Stock holders in the six months ended June 30, 2011.

Three and Six Months Ended June 30, 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 2011 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 313 million shares of our common stock were outstanding at June 30, 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 98 million and 106 million dilutive shares in the three and six months ended June 30, 2012.

Diluted earnings per share included the effect of 17 million unvested RSUs granted to certain global executives. The Adjustment Shares were excluded from the computation of basic and diluted earnings per share as the condition that would result in the issuance of the Adjustment Shares was not satisfied.

Three and Six Months Ended June 30, 2011

Warrants to purchase 317 million shares of our common stock were outstanding, 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 our common stock. Under the treasury stock method, the assumed exercise of warrants to purchase the remaining warrants resulted in 147 million and 154 million dilutive shares in the three and six months ended June 30, 2011.

Diluted earnings per share included the effect of 14 million unvested RSUs granted to certain global executives. The Adjustment Shares were excluded from the computation of basic and diluted earnings per share as the condition that would result in the issuance of the Adjustment Shares was not satisfied.

In July 2011 the 61 million shares of common stock contributed to our pension plans in January 2011 met the criteria to qualify as plan assets for accounting purposes. These shares were not considered outstanding for earnings per share purposes in the three and six months ended June 30, 2011.

Stock Incentive Plans (Notes)

Stock Incentive Plans [Abstract]

Disclosure of Stock Incentive Plans [Text Block]

Stock Incentive Plans

Long-Term Incentive Plan

We granted 7 million and 5 million RSUs valued at the grant date fair value of our common stock in the six months ended June 30, 2012 and 2011. These awards granted either cliff vest or ratably vest generally 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 2012 awards granted to the Top 25 highest compensated employees will settle on the second and third anniversary dates of grant in 25% increments in conjunction with each 25% of our Troubled Asset Relief Program (TARP) obligations that are repaid. 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.

The 2011 awards granted to the Top 25 highest compensated employees will settle three years from the grant date in 25% increments in conjunction with each 25% of our TARP obligations that are repaid. The awards for the Next 75 highest compensated employees will settle either: (1) three years from the date of grant; or (2) on the first 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.

Salary Stock

In the six months ended June 30, 2012 and 2011 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 will 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
RSUs outstanding at January 1, 2012	22.5		$	23.01	1.1
Granted	8.0		$	25.11
Settled	(1.9	)	$	31.65
Forfeited or expired	(0.7	)	$	25.02
RSUs outstanding at June 30, 2012	27.9		$	22.95	1.2
RSUs unvested and expected to vest at June 30, 2012	18.0		$	23.62	1.5
RSUs vested and payable at June 30, 2012	9.3		$	21.47	—

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



	Three Months Ended				Six Months Ended
	June 30, 2012		June 30, 2011		June 30, 2012		June 30, 2011
Compensation expense	$	55	$	60	$	127	$	113

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 June 30, 2012 the total unrecognized compensation expense for nonvested equity awards was $307 million. This expense is expected to be recorded over a weighted-average period of 1.5 years.

The total fair value of RSUs that vested in the six months ended June 30, 2012 and 2011 was $82 million and $49 million.

This amount is offset by net sales for vehicles sold to Ally Financial for employee and governmental lease programs and third party resale purposes.


(b)	Represents cost of sales on the sale of vehicles to Ally Financial for employee and governmental lease programs and third party resale purposes.


(c)	Represents income on investments in Ally Financial preferred stock (through March 31, 2011) and exclusivity and royalty fee income. Included in this amount is rental income related to Ally Financial's primary executive and administrative offices located in the Renaissance Center in Detroit, Michigan. The lease agreement expires in November 2016.


(d)	Represents interest incurred on notes payable and wholesale settlements. In January 2012 we received $21 million from Ally Financial as part of a settlement of previously overcharged interest.

Fair Value of Ally Financial Common Stock

At June 30, 2012 and December 31, 2011 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 June 30, 2012 and December 31, 2011 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 described below. The measurement of Ally Financial common stock is a Level 3 fair value measurement.

At December 31, 2011 we determined the carrying amount of our investment in Ally Financial common stock exceeded our estimate of its fair value. Our estimate of fair value resulted from broader macroeconomic uncertainties and volatility in the financial markets including the eurozone debt crisis, continued heightened risk of recession and concerns about Ally Financial's mortgage related operations. Our estimate considered the potential effect of contractual provisions held by the United States Department of the Treasury who may receive incremental ownership interest in Ally Financial depending upon Ally Financial's equity value at the time of a successful public offering or private sale. These contractual provisions could result in significant dilution of our ownership interest. Based on an evaluation of the duration and severity of this decline in fair value, we concluded the impairment was other-than-temporary. As a result we recorded an impairment charge of $555 million in Interest income and other non-operating income, net to reduce our investment to its estimated fair value of $403 million.

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



	June 30, 2012		December 31, 2011
Carrying amount	$	404	$	403
Fair value	$	436	$	403

Ally Financial Preferred Stock

In March 2011 our investment in Ally Financial preferred stock was sold through a public offering for net proceeds of $1.0 billion. The gain of $339 million related to the sale was recorded in Interest income and other non-operating income, net.

Segment Reporting [Abstract]

Segment Reporting

We analyze the results of our business through our five segments: GMNA, GME, GMIO, GMSA and GM Financial. 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 loaded 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 factors, we do not manage our business on an individual brand or vehicle basis. 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.

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, 2012 we also had equity ownership stakes directly or indirectly in entities through various regional subsidiaries, including GM Korea, SGM, 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.

In 2012 we recorded gains and losses on extinguishment of debt within Corporate for segment reporting purposes. Previously gains and losses on extinguishment of debt were recorded within the applicable automotive segments. This change is consistent with how management currently views the results of our operations.

All intersegment balances and transactions have been eliminated in consolidation.

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

Basis Of Presentation And Recent Accounting Standards (Policies)	6 Months Ended
	Jun. 30, 2012
Basis of Presentation and Recent Accounting Standards [Abstract]
New Accounting Pronouncements Policy [Policy Text Block]	Recently Adopted Accounting Principles In 2012 we adopted the provisions of Accounting Standards Update (ASU) 2011-05, “Presentation of Comprehensive Income” (ASU 2011-05) that requires presentation of all non-owner changes in equity in one continuous statement of comprehensive income or in two separate but consecutive statements. We elected to provide a separate statement of comprehensive income for all periods presented. The amendments in this update do not change the items that must be reported in other comprehensive income (OCI) or when an OCI item must be reclassified to net income. The adoption of ASU 2011-05 did not affect our condensed consolidated statements of financial position, results of operations and cash flows. ASU 2011-05 was modified in December 2011 by the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” This update indefinitely defers certain provisions of ASU 2011-05 that require the disclosure of the amount of reclassifications of items from OCI to net income by component of net income and by component of OCI.
Use of Estimates, Policy [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

Tabular disclosure of available-for-sale securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt.

- 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.

- Definition

All amounts that, per contract, are due to the servicer in exchange for servicing the financial asset and would no longer be received by a servicer if the beneficial owners of the serviced assets (or their trustees or agents) were to exercise their actual or potential authority under the contract to shift the servicing to another servicer. Depending on the servicing contract, those fees may include some or all of the difference between the interest rate collected on the asset being serviced and the rate to be paid to the beneficial owners of the asset.
