Nature Of Operations	12 Months Ended
Nature Of Operations	Dec. 31, 2012
Nature of Operations [Abstract]
Nature Of Operations	General Motors Company was formed in 2009 originally as a Delaware limited liability company, Vehicle Acquisition Holdings LLC, and subsequently converted to a Delaware corporation, NGMCO, Inc. This company, which on July 10, 2009 acquired substantially all of the assets and assumed certain liabilities of General Motors Corporation through a Section 363 sale under Chapter 11 of the U.S. Bankruptcy Code (363 Sale) and changed its name to General Motors Company, is sometimes referred to in these consolidated financial statements for the periods on or subsequent to July 10, 2009 as “we,” “our,” “us,” “ourselves,” the “Company,” “General Motors,” or “GM.” General Motors Corporation is sometimes referred to in these consolidated financial statements, for the periods on or before July 9, 2009, as “Old GM” as it is the predecessor entity solely for accounting and financial reporting purposes. Old GM was renamed Motors Liquidation Company (MLC), which was dissolved on December 15, 2011 and transferred its remaining assets and liabilities to the Motors Liquidation Company GUC Trust (GUC Trust). We design, build and sell cars, trucks and automobile parts worldwide. We also provide automotive financing services through General Motors Financial Company, Inc. (GM Financial). We analyze the results of our business through our five segments: GM North America (GMNA), GM Europe (GME), GM International Operations (GMIO), GM South America (GMSA) and GM Financial. Nonsegment operations are classified as Corporate. Corporate includes investments in Ally Financial, Inc. (Ally Financial), certain centrally recorded income and costs, such as interest, income taxes and corporate expenditures and certain nonsegment specific revenues and expenses.

Basis Of Presentation And Recent Accounting Standards	12 Months Ended
Basis Of Presentation And Recent Accounting Standards	Dec. 31, 2012
Basis Of Presentation
Basis of Presentation	Basis of Presentation Principles of Consolidation The consolidated financial statements include our accounts and those of our subsidiaries that we control due to ownership of a majority voting interest and our consolidated variable interest entities (VIEs) of which we are the primary beneficiary. We continually evaluate our involvement with VIEs to determine whether we have variable interests and are the primary beneficiary of the VIE. When these criteria are met, we are required to consolidate the VIE. Our share of earnings or losses of nonconsolidated affiliates is included in our consolidated operating results using the equity method of accounting when we are able to exercise significant influence over the operating and financial decisions of the affiliate. We use the cost method of accounting if we are not able to exercise significant influence over the operating and financial decisions of the affiliate. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates in the Preparation of the Financial Statements The 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. GM Financial The amounts presented for GM Financial have been adjusted to include the effect of our tax attributes on GM Financial's deferred tax positions and provision for income taxes since the date of acquisition, which are not applicable to GM Financial on a stand-alone basis, and to eliminate the effect of transactions between GM Financial and the other members of the consolidated group. Accordingly, the amounts presented will differ from those presented by GM Financial on a stand-alone basis. Change in Presentation of Financial Statements In 2012 we changed the presentation of our consolidated balance sheet, consolidated statements of cash flows and certain notes to the 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 changed their functional currency from Bolivar Fuerte (BsF), the local currency, to the U.S. Dollar, our reporting currency, on January 1, 2010 because of the hyperinflationary status of the Venezuelan economy. In January 2010 there was a devaluation of the Venezuelan currency and establishment of dual fixed exchange rates, an essential rate and a nonessential rate. In June 2010 the Venezuelan government introduced additional foreign currency exchange control regulations, which imposed restrictions on the use of the parallel foreign currency exchange market, thereby making it more difficult to convert BsF to U.S. Dollars. The restrictions on the foreign currency exchange market 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 as well as our ability to fully benefit from these operations. Effective January 1, 2011 the BsF was further devalued and the essential rate was eliminated. The devaluation has affected results of operations from that date forward because our Venezuelan subsidiaries no longer realize gains that result from favorable foreign currency exchanges processed by the Venezuela currency exchange agency at the essential rate. The aggregate net assets of our Venezuelan subsidiaries at December 31, 2012 and 2011 were $786 million and $438 million. At December 31, 2012 and 2011 other consolidated entities have receivables from our Venezuelan subsidiaries of $379 million and $380 million. The total amounts pending government approval for settlement at December 31, 2012 and 2011 were BsF 2.2 billion (equivalent to $523 million) and BsF 2.3 billion (equivalent to $535 million), for which some requests have been pending from 2007. In February 2013 the Venezuelan government announced that the official fixed exchange rate of BsF 4.3 to $1.00 would be changed to BsF 6.3 to $1.00. The devaluation did not have an effect on the 2012 consolidated financial statements; however, the devaluation will require remeasurement of our Venezuelan subsidiaries' non-U.S. dollar denominated monetary assets and liabilities in the three months ending March 31, 2013. The devaluation effective date is February 13, 2013 and is expected to result in a charge in the range of $150 million to $200 million.

Significant Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Significant Accounting Policies

The accounting policies which follow are utilized by our automotive and automotive financing operations, unless otherwise indicated.

Revenue Recognition

Automotive

Automotive sales and revenue are primarily composed of revenue generated from the sale of vehicles. Vehicle sales are recorded when title and all risks and rewards of ownership have passed to our customers. For the majority of our automotive sales, this occurs when a vehicle is released to the carrier responsible for transporting to a dealer and when collectability is reasonably assured. Vehicle sales are recorded when the vehicle is delivered to the dealer in most remaining cases. Provisions for recurring dealer and customer sales and leasing incentives, consisting of allowances and rebates, are recorded as reductions to Automotive sales and revenue at the time of vehicle sales. All other incentives, allowances, and rebates related to vehicles previously sold are recorded as reductions to Automotive sales and revenue when announced.

Vehicle sales to daily rental car companies with guaranteed repurchase obligations are accounted for as operating leases. Estimated lease revenue is recorded ratably over the estimated term of the lease based on the difference between net sales proceeds and the guaranteed repurchase amount. The difference between the cost of the vehicle and estimated residual value is depreciated on a straight-line basis over the estimated term of the lease.

Automotive Financing - GM Financial

Finance income earned on receivables is recognized using the effective interest method. Fees and commissions (including incentive payments) received and direct costs of originating loans are deferred and amortized over the term of the related finance receivables using the effective interest method and are removed from the consolidated balance sheets when the related finance receivables are sold, charged off or paid in full. Accrual of finance charge income is suspended on accounts that are more than 60 days delinquent, accounts in bankruptcy, and accounts in repossession. Payments received on nonaccrual loans are first applied to any fees due, then to any interest due and then any remaining amounts are recorded to principal. Interest accrual resumes once an account has received payments bringing the delinquency to less than 60 days past due.

Income from operating lease assets, which includes lease origination fees, net of lease origination costs and incentives, is recorded as operating lease revenue on a straight-line basis over the term of the lease agreement.

Fair Value Measurements

A three-level valuation hierarchy, based upon observable and unobservable inputs, is used for fair value measurements. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions based on the best evidence available. These two types of inputs create the following fair value hierarchy:


•	Level 1 - Quoted prices for identical instruments in active markets;


•	Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose significant inputs are observable; and


•	Level 3 - Instruments whose significant inputs are unobservable.

Financial instruments are transferred in and/or out of Level 1, 2 or 3 at the beginning of the accounting period in which there is a change in the valuation inputs.

Marketable Securities

We classify marketable securities as available-for-sale or trading. Various factors, including turnover of holdings and investment guidelines, are considered in determining the classification of securities. Available-for-sale securities are recorded at fair value with unrealized gains and losses recorded, net of related income taxes, in Accumulated other comprehensive income until realized. Trading securities are recorded at fair value with changes in fair value recorded in Interest income and other non-operating income, net. We determine realized gains and losses for all securities using the specific identification method.

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. Securities are classified in Level 1 when quoted prices in an active market for identical securities are available. If quoted market prices are not available, fair values of securities are determined using prices from a pricing service, pricing models, quoted prices of securities with similar characteristics or discounted cash flow models and are generally classified in Level 2. These prices represent non-binding quotes. U.S. government and agency securities, sovereign debt, certificates of deposit, and corporate debt securities are classified as Level 2. Our pricing vendor 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 our pricing service. This review 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 speeds. Based on our review we believe the prices received from our pricing service are a reliable representation of exit prices. Securities are classified in Level 3 in certain cases where there are unobservable inputs to the valuation in the marketplace. Level 3 financial instruments typically include, in addition to the unobservable inputs, observable components that are validated to external sources.

An evaluation is made quarterly to determine if unrealized losses related to non-trading investments in securities are other-than- temporary. Factors considered in determining whether a loss on a marketable security is other-than-temporary include: (1) the length of time and extent to which the fair value has been below cost; (2) the financial condition and near-term prospects of the issuer; and (3) the intent to sell or likelihood to be forced to sell the security before any anticipated recovery.

Finance Receivables

Pre-Acquisition Consumer Finance Receivables

Finance receivables originated prior to the acquisition of AmeriCredit Corp. (AmeriCredit) were adjusted to fair value at October 1, 2010. As a result of the acquisition the allowance for loan losses at October 1, 2010 was eliminated and a net discount was recorded on the receivables. The fair value of the receivables was less than the principal amount of those receivables, thus resulting in a discount to par. This discount was attributable, in part, to future credit losses that did not exist at the origination of the receivables.

A non-accretable difference is the excess between a loan's contractually required payments (undiscounted amount of all uncollected principal and contractual interest payments, both past due and scheduled for the future) and the amount of the loan's cash flows expected to be collected. An accretable yield is the excess in the loan's cash flows expected to be collected over the initial investment in the loan, which at October 1, 2010 was fair value.

As a result of acquisition accounting GM Financial evaluated the common risk characteristics of the loan portfolio and split it into several pools. GM Financial's policy is to remove a charged off loan individually from a pool based on comparing any amount received with its contractual amount. Any difference between these amounts is absorbed by the non-accretable difference. This removal method assumes that the amount received approximates pool performance expectations. The remaining accretable yield balance is unaffected and any material change in remaining effective yield caused by this removal method is addressed by GM Financial's quarterly cash flow evaluation process for each pool. For loans that are resolved by payment in full there is no release of the non-accretable difference for the pool because there is no difference between the amount received and the contractual amount of the loan.

Any deterioration in the performance of the pre-acquisition receivables will result in recording an incremental provision for loan losses. Improvements in the performance of the pre-acquisition receivables which results in a significant increase in actual or expected cash flows will result first in the reversal of any incremental related allowance for loan losses and then in a transfer of the excess from the non-accretable difference to accretable yield, which will be recorded as finance charge income over the remaining life of the receivables.

Post-Acquisition Consumer Finance Receivables and Allowance for Loan Losses

Finance receivables originated after the acquisition of AmeriCredit are carried at amortized cost, net of allowance for loan losses. Provisions for loan losses are charged to operations in amounts sufficient to maintain an allowance for loan losses at a level considered adequate to cover probable credit losses inherent in GM Financial's post-acquisition finance receivables.

The allowance for loan losses is established systematically based on the determination of the amount of probable credit losses inherent in the post-acquisition finance receivables as of the balance sheet date. GM Financial reviews charge-off experience factors, delinquency reports, historical collection rates, estimates of the value of the underlying collateral, economic trends, such as unemployment rates, and other information in order to make the necessary judgments as to probable credit losses. GM Financial also uses historical charge-off experience to determine a loss confirmation period, which is defined as the time between when an event, such as delinquency status, giving rise to a probable credit loss occurs with respect to a specific account and when such account is charged off. This loss confirmation period is applied to the forecasted probable credit losses to determine the amount of losses inherent in finance receivables at the balance sheet date. Assumptions regarding credit losses and loss confirmation periods are reviewed periodically and may be impacted by actual performance of finance receivables and changes in any of the factors discussed above. Should the credit loss assumption or loss confirmation period increase, there would be an increase in the amount of allowance for loan losses required, which would decrease the net carrying value of finance receivables and increase the amount of provision for loan losses recorded on the consolidated statements of operations.

Inventory

Inventories are stated at the lower of cost or market.

Market, which represents selling price less cost to sell, considers general market and economic conditions, periodic reviews of current profitability of vehicles, product warranty costs and the effect of current incentive offers at the balance sheet date. Market for off-lease and other vehicles is current auction sales proceeds less disposal and warranty costs. Productive material, work in process, supplies and service parts are reviewed to determine if inventory quantities are in excess of forecasted usage, or if they have become obsolete.

Equipment on Operating Leases, net

Equipment on operating leases, net is reported at cost, less accumulated depreciation, net of origination fees or costs, and lease incentives. Estimated income from operating lease assets, which includes lease origination fees, net of lease origination costs, is recorded as operating lease revenue on a straight-line basis over the term of the lease agreement. Depreciation of vehicles is provided on a straight-line basis to an estimated residual value over the term of the lease agreement.

We have significant investments in vehicles in operating lease portfolios, which are composed of vehicle leases to retail customers with lease terms of up to 60 months and vehicles leased to rental car companies with lease terms that average nine months or less. We are exposed to changes in the residual values of those assets. For impairment purposes, the residual values represent estimates of the values of the vehicles leased at the end of the lease contracts and are determined based on forecasted auction proceeds when there is a reliable basis to make such a determination. Realization of the residual values is dependent on the future ability to market the vehicles under the prevailing market conditions. The adequacy of the estimate of the residual value is evaluated over the life of the lease and adjustments may be made to the extent the expected value of the vehicle at lease termination changes. Adjustments may be in the form of revisions to the depreciation rate or recognition of an impairment charge. Impairment is determined to exist if the expected future cash flows, which include estimated residual values, are lower than the carrying amount of the vehicles leased. If the carrying amount is considered impaired, an impairment charge is recorded for the amount by which the carrying amount exceeds the fair value. Fair value is determined primarily using the anticipated cash flows, including estimated residual values.

In our Automotive operations when a leased vehicle is returned the asset is reclassified from Equipment on operating leases, net to Inventories at the lower of cost or estimated selling price, less cost to sell. In our Automotive Finance operations when a leased vehicle is returned or repossessed the asset is recorded in Other assets at the lower of cost or estimated selling price, less costs to sell. Upon disposition a gain or loss is recorded for any difference between the net book value of the lease asset and the proceeds from the disposition of the asset.

Impairment charges related to Equipment on operating leases, net are recorded in Automotive cost of sales or GM Financial operating and other expenses.

Valuation of Cost and Equity Method Investments

When events and circumstances warrant, investments accounted for under the cost or equity method of accounting are evaluated for impairment. An impairment charge is recorded whenever a decline in value of an investment below its carrying amount is determined to be other-than-temporary. In determining if a decline is other-than-temporary, factors such as the length of time and extent to which the fair value of the investment has been less than the carrying amount of the investment, the near-term and longer-term operating and financial prospects of the affiliate and the intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery are considered. Impairment charges related to equity method investments are recorded in Equity income, net of tax and gain on investments. Impairment charges related to cost method investments are recorded in Interest income and other non-operating income, net.

Property, net

Property, plant and equipment, including internal use software, is recorded at cost. Major improvements that extend the useful life or add functionality of property are capitalized. The gross amount of assets under capital leases is included in property, plant and equipment. Expenditures for repairs and maintenance are charged to expense as incurred. We depreciate all depreciable property using the straight-line method. Leasehold improvements are amortized over the period of lease or the life of the asset, whichever is shorter. The amortization of the assets under capital leases is included in depreciation expense. Upon retirement or disposition of property, plant and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recorded in earnings. Impairment charges related to property are recorded in Automotive cost of sales, Automotive selling, general and administrative expense or GM Financial operating and other expenses.

Special Tools

Special tools represent product-specific powertrain and non-powertrain related tools, dies, molds and other items used in the vehicle manufacturing process. Expenditures for special tools are recorded at cost and are capitalized. We amortize all non-powertrain special tools over their estimated useful lives using an accelerated amortization method. We amortize powertrain special tools over their estimated useful lives using the straight-line method. Impairment charges related to special tools are recorded in Automotive cost of sales.

Goodwill

Goodwill arises from the application of fresh-start reporting and acquisitions accounted for as business combinations. Goodwill is tested for impairment for all reporting units on an annual basis during the fourth quarter, or more frequently, if events occur or circumstances change that would warrant such a review. When the fair value of a reporting unit falls below its carrying amount an impairment charge is recorded for the amount, if any, by which the carrying amount of goodwill exceeds its implied fair value. Fair values of reporting units are established using a discounted cash flow method. Where available and as appropriate, comparative market multiples and the quoted market price for our common stock are used to corroborate the results of the discounted cash flow method. Our reporting units are GMNA, GME, GM Financial and various reporting units within the GMIO and GMSA segments. Due to the integrated nature of our manufacturing operations and the sharing of assets, other resources and vehicle platforms among brands within GMNA and GME and because financial information by brand or country is not discrete below the operating segment level, GMNA and GME do not contain reporting units below the operating segment level. GM Financial also does not contain reporting units below the operating segment level. GMIO and GMSA are less integrated given the lack of regional trade pacts and other unique geographical differences and thus contain separate reporting units below the operating segment level. Goodwill would be reassigned on a relative-fair-value basis to a portion of a reporting unit to be disposed of or upon the reorganization of the composition of one or more of our reporting units, unless the reporting unit was never integrated.

Intangible Assets, net

Intangible assets, excluding Goodwill, primarily include brand names (including defensive intangibles associated with discontinued brands), technology and intellectual property, customer relationships and dealer networks.

Intangible assets are amortized on a straight-line or an accelerated method of amortization over their estimated useful lives. An accelerated amortization method reflecting the pattern in which the asset will be consumed is utilized if that pattern can be reliably determined. If that pattern cannot be reliably determined, a straight-line amortization method is used. We consider the period of expected cash flows and underlying data used to measure the fair value of the intangible assets when selecting a useful life. Impairment charges related to intangible assets are recorded in Automotive selling, general and administrative expense or Automotive cost of sales.

Amortization of developed technology and intellectual property is recorded in Automotive cost of sales. Amortization of brand names, customer relationships and our dealer networks is recorded in Automotive selling, general and administrative expense or GM Financial operating and other expenses.

Valuation of Long-Lived Assets

The carrying amount of long-lived assets and finite-lived intangible assets to be held and used in the business are evaluated for impairment when events and circumstances warrant. If the carrying amount of a long-lived asset group is considered impaired, a loss is recorded based on the amount by which the carrying amount exceeds fair value. Product-specific long-lived asset groups are tested for impairment at the platform or vehicle line level. Non-product specific long-lived assets are tested for impairment on a reporting unit basis in GMNA, GME, and GM Financial and tested at or within our various reporting units within our GMIO and GMSA segments. Fair value is determined using either the market or sales comparison approach, cost approach or anticipated cash flows discounted at a rate commensurate with the risk involved. Long-lived assets to be disposed of other than by sale are considered held for use until disposition. Product-specific assets may become impaired as a result of declines in profitability due to changes in volume, pricing or costs.

Pension and Other Postretirement Plans

Attribution, Methods and Assumptions

The cost of benefits provided by defined benefit pension plans is recorded in the period employees provide service. The cost of pension plan amendments that provide for benefits already earned by plan participants is amortized over the expected period of benefit which may be: (1) the duration of the applicable collective bargaining agreement specific to the plan; (2) expected future working lifetime; or (3) the life expectancy of the plan participants.

The cost of medical, dental, legal service and life insurance benefits provided through postretirement benefit plans is recorded in the period employees provide service. The cost of postretirement plan amendments that provide for benefits already earned by plan participants is amortized over the expected period of benefit which may be the average period to full eligibility or the average life expectancy of the plan participants, or the period to the plan's termination date for the plan which provides legal services.

An expected return on plan asset methodology is utilized to calculate future pension expense for certain significant funded benefit plans. A market-related value of plan assets methodology is also utilized that averages gains and losses on the plan assets over a period of years to determine future pension expense. The methodology recognizes 60% of the difference between the fair value of assets and the expected calculated value in the first year and 10% of that difference over each of the next four years.

The discount rate assumption is established for each of the retirement-related benefit plans at their respective measurement dates. In the U.S. we use a cash flow matching approach that uses projected cash flows matched to spot rates along a high quality corporate yield curve to determine the present value of cash flows to calculate a single equivalent discount rate.

The benefit obligation for pension plans in Canada, the United Kingdom and Germany represents 92% of the non-U.S. pension benefit obligation at December 31, 2012. The discount rates for plans in Canada, the United Kingdom and Germany are determined using a cash flow matching approach, similar to the U.S. approach.

In countries other than the U.S., Canada, United Kingdom and those located in the Eurozone discount rates are established depending on the local financial markets, using a high quality yield curve based on local bonds, a yield curve adjusted to reflect local conditions using foreign currency swaps or local actuarial standards.

Plan Asset Valuation

Cash Equivalents and Other Short-Term Investments

Money market funds and other similar short-term investment funds are valued using the net asset value per share (NAV) as provided by the investment sponsor or third-party administrator. Prices for short-term debt securities are received from independent pricing services or from dealers who make markets in such securities. Independent pricing services utilize matrix pricing which considers readily available inputs such as the yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices. Money market mutual funds which provide investors with the ability to redeem their interests on a daily basis and for which NAVs are publicly available are classified in Level 1. Other cash equivalents and short-term investments are classified in Level 2.

Common and Preferred Stock

Common and preferred stock for which market prices are readily available at the measurement date, are valued at the last reported sale price or official closing price on the primary market or exchange on which they are actively traded and are classified in Level 1. Such equity securities for which the market is not considered to be active are valued via the use of observable inputs, which may include, among others, the use of adjusted market prices last available, bids or last available sales prices and/or other observable inputs and are classified in Level 2. Common and preferred stock classified in Level 3 are those privately issued securities or other issues that are valued via the use of valuation models using significant unobservable inputs that generally consider among others, aged (stale) pricing, earnings multiples, discounted cash flows and/or other qualitative and quantitative factors. We may consider other security attributes such as liquidity and market activity in assessing the observability of inputs used by pricing services or dealers, which may affect classification in the fair value hierarchy.

Government, Agency and Corporate Debt Securities

U.S. government and government agency obligations, foreign government and government agency obligations, municipal securities, supranational obligations, corporate bonds, bank notes, and preferred securities are valued based on quotations received from independent pricing services or from dealers who make markets in such securities. Debt securities which are priced via the use of pricing services that utilize matrix pricing which considers readily observable inputs such as the yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices, are classified in Level 2. Securities within this category that are typically priced by dealers and pricing services via the use of proprietary pricing models which incorporate significant unobservable inputs are classified in Level 3. These inputs primarily consist of yield and credit spread assumptions. We may consider other security attributes such as liquidity, market activity, price level, credit ratings and geo-political risk in assessing the observability of inputs used by pricing services or dealers, which may affect classification.

Agency and Non-Agency Mortgage and Other Asset-Backed Securities

U.S. and foreign government agency mortgage and asset-backed securities, non-agency collateralized mortgage obligations, commercial mortgage securities, residential mortgage securities and other asset-backed securities are valued based on quotations received from independent pricing services or from dealers who make markets in such securities. Securities which are priced via the use of pricing services that utilize matrix pricing which considers readily observable inputs such as prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices are classified in Level 2. Securities within this category that are typically priced by dealers and pricing services via the use of proprietary pricing models which incorporate significant unobservable inputs are classified in Level 3. These inputs primarily consist of prepayment curves, discount rates, default assumptions and recovery rates. We may consider other security attributes such as liquidity, market activity, price level and other factors in assessing the observability of inputs used by pricing services or dealers, which may affect classification.

Investment Funds, Private Equity and Debt Investments and Real Estate Investments

Investments in exchange traded funds, real estate investment trusts and mutual funds, for which market quotations are generally readily available, are valued at the last reported sale price, official closing price or publicly available NAV (or its equivalent) on the primary market or exchange on which they are traded, and are classified in Level 1. Investments in private investment funds (including hedge funds, private equity funds and real estate funds) are generally valued based on their respective NAV (or its equivalent), as a practical expedient to estimate fair value due to the absence of readily available market prices. Investments in private investment funds, which may be fully redeemed at NAV in the near-term are generally classified in Level 2. Investments in funds, which may not be fully redeemed at NAV in the near-term, are generally classified in Level 3.

Direct investments in private equity, private debt and real estate securities, are generally valued in good faith via the use of the market approach (earnings multiples from comparable companies) or the income approach (discounted cash flow techniques), and consider inputs such as revenue growth and gross margin assumptions, discount rates, discounts for lack of liquidity, market capitalization rates, and the selection of comparable companies. As these valuations incorporate significant unobservable inputs they are classified as Level 3.

Fair value estimates for private investment funds, private equity, private debt, and real estate investments are provided by the respective investment sponsors or investment advisers and are subsequently reviewed and approved by management. In the event management concludes a reported NAV or fair value estimate (collectively, external valuation) does not reflect fair value or is not determined as of the financial reporting measurement date, we will consider whether an adjustment is necessary. In determining whether an adjustment to the external valuation is required, we will review material factors that could affect the valuation, such as changes to the composition or performance of the underlying investment(s) or comparable investments, overall market conditions, expected sale prices for private investments which are probable of being sold in the short term, and other economic factors that may possibly have a favorable or unfavorable effect on the reported external valuation. We may adjust the external valuation to ensure fair value as of the balance sheet date.

Derivatives

Exchange traded derivatives, such as options and futures, for which market quotations are readily available, are valued at the last reported sale price or official closing price on the primary market or exchange on which they are traded and are classified in Level 1. Over-the-counter derivatives, including but not limited to swaps, swaptions and forwards, which are typically valued through independent pricing services with observable inputs are generally classified in Level 2. Derivatives classified in Level 3 are typically valued via the use of pricing models which incorporate significant unobservable inputs, but may also include derivatives which are valued with the use of significant observable inputs which are not subject to corroboration. The inputs part of the model based valuations may include extrapolated or model-derived assumptions such as volatilities and yield and credit spread assumptions.

Due to the lack of timely available market information for certain investments in the asset classes described above as well as the inherent uncertainty of valuation, reported fair values may differ from fair values that would have been used had timely available market information been available.

Extended Disability Benefits

Estimated extended disability benefits are accrued ratably over the employee's active service period using measurement provisions similar to those used to measure our other postretirement benefits (OPEB) obligations. The liability is composed of the future obligations for income replacement, healthcare costs and life insurance premiums for employees currently disabled and those in the active workforce who may become disabled. Future disabilities are estimated in the current workforce using actuarial methods based on historical experience. We record actuarial gains and losses immediately in earnings.

Labor Force

On a worldwide basis, we have a concentration of the workforce working under the guidelines of unionized collective bargaining agreements. At December 31, 2012 50,000 of our U.S. employees (or 62%) were represented by unions, the majority of which were represented by the International Union, United Automobile, Aerospace and Agriculture Implement Workers of America (UAW). The current labor contract with the UAW is effective for a four-year term that began in October 2011 and expires in September 2015. The contract included a $5,000 lump sum payment to each eligible UAW employee in the year ended December 31, 2011 and three additional lump-sum payments of $1,000 to be paid annually in the years ending December 31, 2012, 2013 and 2014. These lump-sum payments expected to total $381 million are being amortized over the four-year contract period.

Job Security Programs

Effective with our current labor agreement with the UAW the Job Opportunity Bank Program was eliminated and the Supplemental Unemployment Benefit (SUB) program and the Transitional Support Program (TSP) were retained. These modified job security programs provide employees reduced wages and continued coverage under certain employee benefit programs depending on the employee's classification as well as the number of years of service that the employee has accrued. A similar tiered benefit is provided to Canadian Auto Workers Union (CAW) employees. We recognize a liability for these SUB/TSP benefits over the expected service period of employees, based on our best estimate of the probable liability at the measurement date.

Stock Incentive Plans

We measure and record compensation expense for all share-based payment awards based on the award's estimated fair value which is the fair value of our common stock on the date of grant, or for restricted stock units (RSUs) granted prior to our public offering, the fair value of our common stock as of the date of the public offering. We record compensation cost for the awards on a straight-line basis over the entire vesting period, or for retirement eligible employees over the requisite service period.

Salary stock awards granted are fully vested and nonforfeitable upon grant; therefore, compensation cost is recorded on the date of grant.

The liability for stock incentive plan awards settled in cash is remeasured to fair value at the end of each reporting period.

Policy, Product Warranty and Recall Campaigns

The estimated costs related to policy and product warranties are accrued at the time products are sold and are charged to Automotive cost of sales. These estimates are established using historical information on the nature, frequency and average cost of claims of each vehicle line or each model year of the vehicle line and assumptions about future activity and events. Revisions are made when necessary, based on changes in these factors. Trends of claims are actively studied and actions are taken to improve vehicle quality and minimize claims.

The estimated costs related to product recalls are based on a formal campaign soliciting return of that product are accrued when they are deemed to be probable and can be reasonably estimated.

Income Taxes

The liability method is used in accounting for income taxes. Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using the statutory tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recorded in the results of operations in the period that includes the enactment date under the law.

Deferred income tax assets are evaluated quarterly to determine if valuation allowances are required or should be adjusted. We establish valuation allowances for deferred tax assets based on a more likely than not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction. We consider the following possible sources of taxable income when assessing the realization of deferred tax assets:

•Future reversals of existing taxable temporary differences;

•Future taxable income exclusive of reversing temporary differences and carryforwards;

•Taxable income in prior carryback years; and

•Tax-planning strategies.

The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence factors, including but not limited to:

•Nature, frequency, and severity of recent losses;

•Duration of statutory carryforward periods;

•Historical experience with tax attributes expiring unused; and

•Near- and medium-term financial outlook.

It is difficult to conclude a valuation allowance is not required when there is significant objective and verifiable negative evidence, such as cumulative losses in recent years. We utilize a rolling three years of actual and current year anticipated results as the primary measure of cumulative losses in recent years.

Income tax expense (benefit) for the year is allocated between continuing operations and other categories of income such as Discontinued operations or Other comprehensive income (loss). In periods in which there is a pre-tax loss from continuing operations and pre-tax income in another income category, the tax benefit allocated to continuing operations is determined by taking into account the pre-tax income of other categories.

We record uncertain tax positions on the basis of a two-step process whereby: (1) we determine whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position; and (2) for those tax positions that meet the more likely than not recognition, we recognize the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority.

We record interest and penalties on uncertain tax positions in Income tax expense (benefit).

Derivative Instruments

We are party to a variety of foreign currency exchange rate, commodity, interest rate swap and interest rate cap derivative contracts entered into in connection with the management of exposure to fluctuations in certain foreign currency exchange rates, commodity prices and interest rates.

In connection with certain long-term supply contracts that we have entered into, we have identified embedded derivatives which we have bifurcated for valuation and accounting purposes.

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. GM Financial's special purpose entities (SPEs) are contractually required to purchase derivative instruments as credit enhancements in connection with securitization transactions and credit facilities. These financial exposures and contractual requirements are managed in accordance with corporate policies and procedures and a risk management control system is used to assist in monitoring hedging programs, derivative positions and hedging strategies. Hedging documentation includes hedging objectives, practices and procedures and the related accounting treatment.

The accounting for changes in the fair value of each derivative financial instrument depends on whether it has been designated and qualifies as an accounting hedge, as well as the type of hedging relationship identified. Derivative financial instruments entered into by our automotive operations are not designated in hedging relationships. Certain of the derivatives entered into by GM Financial have been designated in cash flow hedging relationships. Derivatives that receive hedge accounting treatment are evaluated for effectiveness at the time they are designated as well as throughout the hedging period. We do not hold derivative financial instruments for speculative purposes.

All derivatives are recorded at fair value and presented gross in the consolidated balance sheets. Internal models are used to value a majority of derivatives. The models use, as their basis, readily observable market inputs, such as time value, forward interest rates, volatility factors and current and forward market prices for foreign currency exchange rates and commodities. We estimate our nonperformance risk using our corporate credit rating, the rating on our secured revolver, and yields on traded bonds of companies with comparable credit ratings and risk profiles. Derivative contracts that are valued based upon models with significant unobservable market inputs, primarily price, are classified in Level 3.

We record the earnings effect resulting from the change in fair value of automotive operations derivative instruments in Interest income and other non-operating income, net. We record the earnings effect resulting from the change in fair value of derivative instruments entered into by GM Financial in GM Financial operating and other expenses.

Effective changes in fair value of derivatives designated as cash flow hedges are recorded in Cash flow hedging gains (losses), net within a separate component of Other comprehensive income (OCI). Amounts are reclassified from Accumulated other comprehensive income when the underlying hedged item affects earnings. All ineffective changes in fair value are recorded in earnings. We also discontinue hedge accounting prospectively when it is determined that a derivative instrument has ceased to be effective as an accounting hedge or if the underlying hedged cash flow is no longer probable of occurring.

We enter into contracts with counterparties that we believe are creditworthy and generally settle on a net basis. We perform a quarterly assessment of our counterparty credit risk, including a review of credit ratings, credit default swap rates and potential nonperformance of the counterparty. Based on our most recent quarterly assessment of our counterparty credit risk, we consider this risk to be low.

The cash flows from derivative instruments are classified in the same categories as the hedged items in the consolidated statement of cash flows.

Foreign Currency Transactions and Translation

The assets and liabilities of foreign subsidiaries, that use the local currency as their functional currency, are translated to U.S. Dollars based on the current exchange rate prevailing at each balance sheet date and any resulting translation adjustments are included in Accumulated other comprehensive income. The assets and liabilities of foreign subsidiaries whose local currency is not their functional currency are remeasured from their local currency to their functional currency, and then translated to U.S. Dollars. Revenues and expenses are translated into U.S. Dollars using the average exchange rates prevailing for each period presented.

Gains and losses arising from foreign currency transactions and the effects of remeasurements discussed in the preceding paragraph are recorded in Automotive cost of sales and GM Financial operating and other expenses unless related to Automotive debt, which are recorded in Interest income and other non-operating income, net.

The following table summarizes the effects of foreign currency transactions and remeasurement (dollars in millions):



	Years Ended December 31,

Foreign currency transaction and remeasurement losses	$	117	$	55	$	210

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 OCI or when an OCI item must be reclassified to net income. The adoption of ASU 2011-05 did not affect our 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

Acquisition and Disposal of Businesses

Sale of General Motors Strasbourg S.A.S.

In December 2012 we entered into a definitive agreement to sell 100% of our equity interest of General Motors Strasbourg S.A.S. (GMS), which was included in our GME segment, for cash of one Euro to an external third-party. GMS is engaged in the business of developing and manufacturing automatic transmissions for luxury and performance light automotive vehicles. We acquired GMS in October 2010 as subsequently discussed. GMS's assets and liabilities were adjusted to their estimated fair value of one Euro upon entering into the definitive agreement. The resulting charge of $119 million was recorded in Interest income and other non-operating income, net. In January 2013 we completed the sale of GMS. GMS's assets, composed primarily of accounts receivable and inventories, and its liabilities composed primarily of accounts payable and accrued liabilities were classified as held for sale and were included in Current Assets and Current Liabilities.

Definitive Agreement to Acquire Certain Ally Financial International Operations

In November 2012 GM Financial entered into an agreement with Ally Financial to acquire 100% of the outstanding equity interests of its automotive finance and financial services operations in Europe and Latin America and a separate agreement to acquire Ally Financial’s non-controlling equity interests in GMAC-SAIC Automotive Finance Company Limited (GMAC-SAIC), which conducts automotive finance and other financial services in China. The combined consideration will be approximately $4.2 billion in cash, subject to certain closing adjustments. These transactions will enable GM Financial to provide automotive finance and other financial services to customers in European, Latin American and Chinese markets. The closings of the transactions contemplated by the agreements are subject to satisfaction of certain closing conditions, including obtaining applicable regulatory approvals and third-party consents and other customary closing conditions, and are expected to close in stages throughout 2013.

Acquisition of SAIC GM Investment Limited

In September 2012 SAIC Motor Hong Kong Investment Limited (SAIC-HK) exercised its option to not participate in future capital injections to SAIC GM Investment Limited, the holding company of General Motors India Private Limited and Chevrolet Sales India Private Limited (collectively HKJV). We agreed with SAIC-HK to settle a promissory note due from HKJV to us in exchange for HKJV's issuance of 257 million Class B shares at face value of $1.17 per share. SAIC-HK's equity interest in HKJV was diluted from 50% to 14% and we obtained control of HKJV with an 86% interest and consolidated HKJV effective September 1, 2012. We recognized a gain of $51 million measured as the difference between the fair value of our 50% interest in HKJV and the investment carrying amount at the date of acquisition of which $50 million was recorded in Equity income, net of tax and gain on investments. In addition we invested $125 million in HKJV and acquired 186 million Class A shares at face value of $0.6708 per share, which increased our interest in HKJV from 86% to 90.8%. Refer to Note 10 for additional details on our investment in HKJV prior to acquisition.

The following table summarizes the consideration paid and the HKJV assets acquired and liabilities assumed, which are included in our GMIO segment (dollars in millions):



	September 1, 2012
Consideration
Fair value of our previously held investment	$	74
Consideration paid for Shanghai Automotive Industry Corporation's (SAIC) portion of the promissory note	150
Settlement of written put option	(94		)
Total consideration	$	130

Fair value of the noncontrolling interest	$	21

Assets acquired and liabilities assumed
Cash	$	17
Accounts receivable	124
Inventory	132
Other current assets	13
Property	385
Goodwill	61
Other non-current assets	59
Current liabilities	(483		)
Non-current liabilities	(157		)
	$	151

When applying the acquisition method of accounting deferred tax assets and related valuation allowances give rise to goodwill, which is a residual. None of the goodwill from this transaction is deductible for tax purposes. We did not provide pro forma financial information because we do not believe the information is material.

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.

Acquisition of AmeriCredit

In October 2010 we acquired 100% of the outstanding equity interests of AmeriCredit, an automotive finance company, renamed General Motors Financial Company, Inc., for cash of $3.5 billion. This acquisition allows us to provide a more complete range of financing options to our customers across the U.S. and Canada, specifically focusing on providing additional capabilities in leasing and sub-prime vehicle financing options.

The following table summarizes the consideration paid, acquisition-related costs, and the assets acquired and liabilities assumed recognized at the acquisition date in connection with the acquisition of AmeriCredit (dollars in millions, except per share amounts):



	October 1, 2010
Consideration
Cash paid to AmeriCredit common shareholders of $24.50 per share	$	3,327
Cash paid to cancel outstanding stock warrants	94
Cash paid to settle equity-based compensation awards	33
Total consideration	$	3,454

Acquisition-related costs(a)	$	43

Assets acquired and liabilities assumed
Cash	$	538
Restricted cash	1,136
Finance receivables(b)	8,231
Other assets, including identifiable intangible assets	200
Securitization notes payable and other borrowings(c)	(7,564		)
Other liabilities	(352		)
Identifiable net assets acquired	2,189
Goodwill resulting from the acquisition of AmeriCredit	1,265
	$	3,454

_________


(a)	Acquisition-related costs of $43 million were expensed as incurred. The acquisition related costs include $27 million recorded in Automotive selling, general and administrative expense and $16 million recorded in GM Financial operating and other expenses.

(b)

The fair value of Finance receivables was determined using a discounted cash flow approach. The contractual cash flows were adjusted for estimated prepayments, defaults, recoveries, finance charge income and servicing costs and discounted using a discount rate commensurate with risks and maturity inherent in the finance contracts. As of the acquisition date, the contractually required payments receivable was $10.7 billion of which $9.7 billion was expected to be collected.


(c)	The fair value of Securitization notes payable and other borrowings was principally determined using quoted market rates.

We recorded goodwill in the amount of $1.3 billion for the excess of consideration paid over the fair value of the individual assets acquired and liabilities assumed. Goodwill includes $153 million recorded to establish a valuation allowance for deferred tax assets that was not applicable to GM Financial on a stand-alone basis. All of the goodwill was assigned to the GM Financial reporting unit. The goodwill expected to be tax deductible is $159 million and was generated from previous acquisitions by GM Financial.

The results of operations of GM Financial are included in our results beginning October 1, 2010. The following table summarizes the actual amounts of revenue and earnings of GM Financial included in our consolidated financial statements for the years ended December 31, 2012, 2011 and 2010, as well as the supplemental pro forma revenue and earnings of the combined entity for the year ended December 31, 2010 as if the acquisition had occurred on January 1, 2010 (dollars in millions):



	GM Financial Amounts For Year Ended December 31,						Pro Forma-Combined (Unaudited)
	2012		2011		2010		Year Ended December 31, 2010
Total net sales and revenue	$	1,961	$	1,410	$	281	$	136,645
Net income attributable to stockholders	$	567	$	440	$	90	$	6,651

The supplemental pro forma information was adjusted to give effect to the tax effected amortization of a premium on finance receivables and a premium on securitization notes payable and other borrowings, depreciation and amortization related to other assets and acquisition related costs. The pro forma information should not be considered indicative of the results had the acquisition been consummated on January 1, 2010, nor are they indicative of future results.

Sale of Nexteer

In November 2010 we completed the sale of Nexteer Automotive Corporation (Nexteer), a manufacturer of steering components and half-shafts, which was included in our GMNA segment, to Pacific Century Motors. The sale of the Nexteer business included the global steering business which was acquired in October 2009.

We received consideration of $426 million in cash and a $39 million promissory note in exchange for 100% of our ownership interest in Nexteer and recorded a gain of $60 million on the sale which is recorded in Interest income and other non-operating income, net. Subsequent to the sale, Nexteer became one of our third-party suppliers. During the year ended December 31, 2010 Nexteer recorded revenue of $1.8 billion, of which $939 million were sales to us.

Acquisition of GMS

In October 2010 we acquired 100% of the outstanding equity interest of GMS for cash of one Euro from MLC. We recorded the fair value of the assets acquired and liabilities assumed as of October 1, 2010 and have included GMS's results of operations and cash flows from that date forward. GMS was sold in January 2013 as previously discussed. The following table summarizes the amounts recorded in connection with the acquisition of GMS, which are included in our GME segment (dollars in millions):



	October 1, 2010
Assets acquired and liabilities assumed
Cash	$	49
Accounts receivable(a)	60
Inventory	56
Property, net	25
Other non-current assets	3
Current liabilities	(116		)
Non-current liabilities	(11		)
Bargain purchase gain	$	66

_________


(a)	Accounts receivable includes $32 million that is due from us.

We determined that the excess of fair value over consideration paid was attributable to potential future restructuring scenarios made necessary due to the uncertainty in sales demand beyond in-place supply agreements. Restructuring costs, if incurred, would be expensed in future periods. As potential future restructuring activities do not qualify to be recorded as a liability in the application of the acquisition method of accounting, none was recorded, and we recorded the excess as a bargain purchase gain, recorded in Interest income and other non-operating income, net. We did not provide the pro forma financial information because we do not believe the information was material.

Saab Sale

In February 2010 we completed the sale of Saab Automobile AB and in May 2010 we completed the sale of Saab Automobile GB (collectively Saab) to Spyker Cars NV. Of the negotiated cash purchase price of $74 million, we received $50 million at closing and received the remainder in July 2010. We also received preference shares in Saab with a face value of $326 million and an estimated fair value that is insignificant and received $114 million as repayment of the debtor-in-possession financing that we provided to Saab during 2009. In the year ended December 31, 2010 we recorded a gain of $123 million in Interest income and other non-operating income, net reflecting cash received of $166 million less net assets with a book value of $43 million.

Finance Receivables, net [Abstract]

Financing Receivables [Text Block]

GM Financial Finance Receivables, net

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

The following table summarizes GM Financial finance receivables, net relating to consumer and commercial activities (dollars in millions):



	December 31, 2012		December 31, 2011
Current	$	4,044	$	3,251
Non-current	6,954		5,911
Total GM Financial finance receivables, net	$	10,998	$	9,162

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



	December 31, 2012			December 31, 2011
Pre-acquisition finance receivables, outstanding balance	$	2,162		$	4,366
Pre-acquisition finance receivables, carrying amount	$	1,958		$	4,027
Post-acquisition finance receivables, net of fees(a)	9,391			5,314
Total finance receivables	11,349			9,341
Less: allowance for loan losses on post-acquisition finance receivables(a)	(351		)	(179		)
Total GM Financial finance receivables, net	$	10,998		$	9,162

__________


(a)	At December 31, 2012 the balance includes finance receivables and loans of $560 million and allowance for loan losses of $6 million in connection with the commercial lending program.

The following table summarizes activity for finance receivables relating to consumer and commercial activities (dollars in millions):



	Years Ended December 31,
	2012			2011

Change in carrying amount adjustment on the pre-acquisition finance receivables	(170		)	(483		)
Balance at end of period	$	11,349		$	9,341

__________


(a)	Includes finance receivables and loans originated of $1.2 billion and principal collections of $667 million in connection with the commercial lending program for the year ended December 31, 2012.

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



	December 31, 2012				December 31, 2011
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
GM Financial finance receivables, net	$	10,998	$	11,313	$	9,162	$	9,386

GM Financial determined the fair value of consumer finance receivables using Level 3 inputs within a cash flow model. The Level 3 inputs reflect assumptions regarding expected prepayments, deferrals, delinquencies, recoveries and charge-offs of the loans within the finance receivable portfolio. The cash flow model produces an estimated amortization schedule of the finance receivables which is the basis for the calculation of the series of cash flows that derive the fair value of the portfolio. The series of cash flows 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 GM Financial's cash flow model.

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

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

At December 31, 2012 and 2011 the accrual of finance charge income has been suspended on delinquent consumer finance receivables based on contractual amounts due of $503 million and $439 million. At December 31, 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. For the period ended December 31, 2012 as a result of improvements in the credit performance of the pre-acquisition portfolio, which resulted in an increase of expected cash flows of $170 million, GM Financial transferred the excess non-accretable difference to accretable yield. GM Financial will recognize this excess as finance charge income over the remaining life of the portfolio.

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



	Years Ended December 31,
	2012			2011
Balance at beginning of period	$	737		$	1,201
Accretion of accretable yield	(503		)	(725		)
Transfer from non-accretable difference	170			261
Balance at end of period	$	404		$	737

The following table summarizes the allowance for post-acquisition loan losses on consumer and commercial finance receivables (dollars in millions):

Credit Quality

Consumer Finance Receivables

Credit bureau scores, generally referred to as FICO scores, are determined during GM Financial's automotive loan origination process. The following table summarizes the credit risk profile of finance receivables by FICO score band, determined at origination (dollars in millions):



	December 31, 2012		December 31, 2011

__________


(a)	Composed of the sum of pre-acquisition consumer finance receivables - outstanding balance and post-acquisition consumer finance receivables, net of fees.

Commercial Finance Receivables

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

Delinquency

Consumer Finance Receivables

The following summarizes the contractual amount of consumer finance receivables, which is not materially different than the recorded investment, more than 30 days delinquent, but not yet in repossession, and in repossession, but not yet charged off (dollars in millions):



	December 31, 2012				December 31, 2011
	Amount		Percent of Contractual Amount Due		Amount		Percent of Contractual Amount Due
Delinquent contracts
31-to-60 days	$	672	6.1	%	$	517	5.3	%
Greater-than-60 days	230		2.1	%	182		1.9	%
Total consumer finance receivables more than 30 days delinquent	902		8.2	%	699		7.2	%
In repossession	31		0.3	%	27		0.3	%
Total consumer finance receivables more than 30 days delinquent and in repossession	$	933	8.5	%	$	726	7.5	%

An account is considered delinquent if a substantial portion of a scheduled payment has not been received by the date such payment was contractually due. Delinquencies may vary from period to period based upon the average age of the portfolio, seasonality within the calendar year and economic factors.

Commercial Finance Receivables

At December 31, 2012 all commercial finance receivables were current with respect to payment status.

Marketable Securities [Abstract]

Marketable Securities [Text Block]

Marketable Securities

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

Peugeot S.A.

At December 31, 2012, we measured the fair value of our investment in Peugeot S.A. (PSA) common stock using the published stock price and determined the carrying amount of our investment in PSA common stock exceeded its fair value. PSA’s stock price has shown no sustained signs of recovery towards the price at which we acquired our seven percent interest in March 2012.

Based upon the 55% decline in PSA common stock price since our acquisition in March 2012 and the nine month duration of the impairment, combined with our fourth quarter reassessment of our European automotive operations, we have concluded that the impairment of our investment in PSA common stock is other-than-temporary. As a result we have transferred the total unrealized losses from Accumulated other comprehensive loss to Interest income and other non-operating income, net resulting in recognition of an impairment charge of $220 million.

GM Korea Preferred Shares

In September 2012 we entered into a transaction to acquire security interests in certain mandatorily redeemable preferred shares issued by GM Korea for $293 million. The transaction did not meet the criteria for an extinguishment of the liability. Subsequently, GM Korea partially redeemed the mandatorily redeemable preferred shares resulting in an extinguishment of the liability and redemption of a portion of the security interests, which is described in more detail in Note 17. The remaining unredeemed interests are classified as available-for-sale corporate debt securities and had a fair value of $177 million at December 31, 2012.

Equity Method Investments and Joint Ventures Disclosure [Text Block]

Equity in Net Assets of Nonconsolidated Affiliates

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

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



	Years Ended December 31,
	2012		2011			2010

Total equity income, net of tax and gain on investments	$	1,562	$	3,192		$	1,438

Sales and income of our joint ventures 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 investments.

We received dividends from nonconsolidated affiliates of $1.4 billion, $1.2 billion and $685 million in the years ended December 31, 2012, 2011 and 2010. At December 31, 2012 and 2011 we had undistributed earnings including dividends declared but not received, of $1.7 billion and $1.6 billion related to our nonconsolidated affiliates.

Investment in China JVs

The following table summarizes our direct ownership interests in China JVs:



	December 31, 2012		December 31, 2011
Shanghai General Motors Co., Ltd. (SGM)	50	%	49	%
Shanghai GM Norsom Motor Co., Ltd. (SGM Norsom)	25	%	25	%
Shanghai GM Dong Yue Motors Co., Ltd. (SGM DY)	25	%	25	%
Shanghai GM Dong Yue Powertrain (SGM DYPT)	25	%	25	%
SAIC-GM-Wuling Automobile Co., Ltd. (SGMW)	44	%	44	%

Pan Asia Technical Automotive Center Co., Ltd.	50	%	50	%
Shanghai OnStar Telematics Co., Ltd. (Shanghai OnStar)	40	%	40	%
Shanghai Chengxin Used Car Operation and Management Co., Ltd. (Shanghai Chengxin Used Car)	33	%	33	%
SAIC General Motors Sales Co., Ltd. (SGMS)	49	%	49	%

SGM is a joint venture established in 1997 by SAIC (50%) and us (50%). 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 Buick, Chevrolet and Cadillac brands. SGM also has interests in Shanghai OnStar (20%) and Shanghai Chengxin Used Car (33%). SGM also has a 20% equity interest in GMAC-SAIC, a joint venture established by General Motors Acceptance Corporation (now Ally Financial) (40%) and SAIC Finance Co., Ltd. (40%) in 2007.

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

In February 2010 we sold a 1% ownership interest in SGM to SAIC-HK, reducing our ownership interest to 49%. The sale of the 1% ownership interest to SAIC was predicated on our ability to work with SAIC to obtain a $400 million line of credit from a commercial bank to us. We also received a call option to repurchase the 1% which was contingently exercisable based on events which we did not unilaterally control. As part of the loan arrangement SAIC provided a commitment whereby, in the event of default, SAIC would purchase the ownership interest in SGM that we pledged as collateral for the loan. We recorded an insignificant gain on the transaction.

In September 2012 we repurchased the 1% interest in SGM for a total consideration of $119 million, increasing our ownership interest in SGM to 50%. The transaction was accounted for by applying the equity method of accounting. The consideration exceeded our proportionate share of the 1% interest in SGM net assets by $82 million, which consists of plant, property and equipment, intangible assets and goodwill of $8 million, $36 million and $38 million.

In November 2010 we purchased an additional 10% interest in SGMW from the Liuzhou Wuling Motors Co., Ltd. and Liuzhou Mini Vehicles Factory, collectively the Wuling Group, for cash of $52 million plus an agreement to provide technical services to the Wuling Group for a period of three years. As a result of this transaction we own 44%, SAIC owns 50.1% and certain Liuzhou investors own 5.9% of the outstanding stock of SGMW.

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 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 HKJV was determined to be less than its carrying amount. 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 provided SAIC-HK, a 50% equity holder in HKJV through September 1, 2012, an option to not participate in future capital injections, which would otherwise be required under certain circumstances. The related option liability was $88 million and total unrealized losses were $64 million at 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 was most sensitive to the fair value of HKJV, which was unobservable. A discounted cash flow methodology was utilized to estimate the fair value of HKJV.

In September 2012 SAIC-HK exercised its option to not participate in future capital injections to HKJV. As a consequence of the decision to not participate in the capital injections and our settlement of a promissory note, SAIC-HK's interest in HKJV was diluted from 50% to 14% and we obtained control of HKJV with an 86% interest. We consolidated the assets and liabilities and the results of operations of HKJV beginning on September 1, 2012. Refer to Note 4 for further detail regarding the acquisition.

VMM Deconsolidation

In June 2011 we entered into a new shareholder agreement with Fiat Powertrain Technologies SPA related to VM Motori (VMM) in Italy. 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 balance sheets and recorded an equity interest in the amount of $46 million.

Investment in and Summarized Financial Data of Nonconsolidated Affiliates

At December 31, 2012 and 2011 the carrying amount of our investments in certain joint ventures exceeded our share of the underlying net assets by $3.8 billion. These differences are primarily related to the application of fresh-start reporting and purchase of additional interests in nonconsolidated affiliates, of which $3.4 billion and $3.3 billion at December 31, 2012 and 2011 were allocated to goodwill and the remainder was allocated to the underlying assets and liabilities, primarily intangibles, and are being amortized over their useful lives.

Also includes other assets whose fair value was determined to be $0 in the years ended December 31, 2012, 2011 and 2010 measured utilizing Level 3 inputs. Fair value measurements of the non-GME asset group long-lived assets utilized projected cash flows discounted at a rate commensurate with the perceived business risks related to the assets involved.


(b)	Included in total depreciation, impairment charges and amortization expense.

GME Impairment Charges

The carrying amounts of substantially all of GME's assets were established at fair value during fresh-start reporting. In the determination of fair value, one of our key inputs was a forecasted cash flow projection. During 2010, our actual cash flows approximated our projection. During the second half of 2011 and continuing into 2012, the European automotive industry has been severely affected by the ongoing sovereign debt crisis, high unemployment and a lack of consumer confidence coupled with overcapacity. During this timeframe, we began to experience deterioration in cash flows. In response, we formulated a plan to implement various actions to strengthen our operations and increase our competitiveness. The key areas of the plan include investments in our product portfolio, a revised brand strategy, significant management changes, reducing material, development and production costs, and further leveraging synergies from the alliance between us and PSA.

We believe it is likely that adverse economic conditions, and their effect on the European automotive industry will not improve significantly in the short-term and we expect to continue to incur losses in the region as a result. During the fourth quarter of 2012, notwithstanding the above described actions, GME performed below expectations relative to the key operating metrics of forecasted revenues, market share, and variable profit established in mid-2012. Further, our industry outlook deteriorated, and our forecast of 2013 cash flows declined. This triggered a long-lived asset impairment analysis.

We performed a recoverability test of the GME asset group by weighting various undiscounted cash flow scenarios. The weighting of the projected cash flows considers the uncertainty in our ability to execute the actions contemplated in our plan which, in part, are dependent upon actions and factors outside our control. Our test concluded that the GME asset group was not recoverable as the resulting undiscounted cash flows were less than their carrying amount. Accordingly, we estimated the fair value of the GME long-lived assets to determine the impairment amount. Determining the fair value is judgmental in nature and requires the use of significant estimates and assumptions, considered to be Level 3 inputs.

To determine the estimated fair value of real and personal property, the cost approach, market approach and income approach were considered. Under the cost approach, the determination of fair value considered the estimates of the cost to construct or purchase a new asset of equal utility at current prices with adjustments in value for physical deterioration, functional obsolescence, and economic obsolescence. Under the market approach, the determination of fair value considered the market prices in transactions for similar assets and certain direct market values based on quoted prices from brokers and secondary market participants for similar assets. Under the income approach, the determination of fair value considered the estimate of the present worth of future benefits derived from ownership, usually measured through the capitalization of a specific level of income which can be derived from the subject asset with adjustments in value for demolition costs and for the effect of an estimated holding period. Under the income approach, it was assumed fair value could not exceed the present value of the net cash flows discounted at a rate commensurate with the level of risk inherent in the subject asset. An in-exchange premise was determined to be the highest and best use.

The following table summarizes the significant Level 3 inputs for real and personal property measurements:



	Valuation Technique(s)	Unobservable Input(s)	Range
Real Property	Market approach	Demolition costs(a)	6% - 23%
	Cost approach	Holding period(b)	0 - 4 years
	Income approach	Discount rate(c)	11.2% - 14.5%
Personal Property	Market approach	Physical deterioration(d)	52% - 69%
	Cost approach	Functional obsolescence(e)	8% - 28%
		Economic obsolescence(f)	17% - 23%

__________


(a)	Represents estimated gross cost to demolish and clear the structures on the property as a percentage of replacement cost new.


(b)	Represents estimated marketing period for each property; which dictates the amount of property specific holding costs to be incurred such as real estate taxes.


(c)	Represents the discount rate for the specific property based on local market sources and available benchmarking data.


(d)	Represents estimates of loss in asset value due to wear and tear, action of the elements, and other physical factors that reduce the life and serviceability of the asset.


(e)	Represents estimated loss in asset value caused by inefficiencies and inadequacies of the asset itself.


(f)	Represents estimated loss in asset value caused by factors external to the asset such as legislative enactments, changes in use, social change, and change in supply and demand.

As a result of our fair value estimates, we adjusted the carrying amount of the GME real and personal property to fair value and recorded asset impairment charges of $3.7 billion at December 31, 2012. These charges were recorded in our GME segment with $3.5 billion recorded in Automotive cost of sales and $0.2 billion recorded in Automotive selling, general and administrative expense. The fair value estimates for GME real and personal property are based on a valuation premise that assumes the assets' highest and best use are different than their current use due to the overall European macro-economic environment.

The following table summarizes GME real and personal property measured at fair value utilizing Level 3 inputs on a nonrecurring basis (dollars in millions):

In the three months ended December 31, 2012, 2011 and 2010 we performed our annual goodwill impairment testing as of October 1 for all reporting units. In addition, in the years ended December 31, 2012 and 2011, we performed event-driven goodwill impairment tests at various dates for certain of our reporting units.

GMNA

Subsequent to our 2012 annual goodwill impairment testing, we reversed $36.2 billion of our deferred tax asset valuation allowances for our GMNA reporting unit. The reversal of the deferred tax asset valuation allowances resulted in the carrying amount of our GMNA reporting unit exceeding its fair value. As a result we performed an event-driven goodwill impairment test in the three months ended December 31, 2012. Based on the results of this event-driven impairment test we recorded a Goodwill impairment charge of $26.4 billion in the three months ended December 31, 2012. At December 31, 2012, GMNA's Goodwill balance was $0. Refer to Note 21 for additional information on the reversal of our deferred tax asset valuation allowances for our U.S. and Canadian operations.

GME

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 beginning Retained earnings. GME continued to have a negative carrying amount and because it was more likely than not further goodwill impairment existed at March 31, 2012 and at December 31, and March 31, 2011, we recorded aggregate Goodwill impairment charges of $590 million and $1.0 billion in the years ended December 31, 2012 and 2011. At March 31, 2012, GME's Goodwill balance was $0.

GMIO

Based on our annual goodwill impairment testing we determined that goodwill was impaired for our GM Korea reporting unit at October 1, 2011, as the fair value of GM Korea decreased below its carrying amount. We performed event-driven goodwill impairment tests for GM Korea for each three month period ended subsequent to October 1, 2011. The decrease in 2011 of GM Korea's fair value was driven by a higher level of anticipated economic weakness in certain markets to which GM Korea exports coupled with lower forecasted margins resulting from higher raw material costs and unfavorable foreign exchange rates. Subsequent to our 2011 annual impairment testing we reversed a deferred tax asset valuation allowance for our GM Holden, Ltd. (Holden) reporting unit that resulted in the carrying amount of this reporting unit exceeding its fair value. At December 31, 2011 Holden's goodwill balance was $0. At October 1, 2012 based on our annual goodwill impairment testing we determined that the fair value of GM South Africa decreased below its carrying amount. Based on the results of our annual and event-driven goodwill impairment tests, we recorded total Goodwill impairment charges of $156 million and $270 million in the years ended December 31, 2012 and 2011 within our GMIO segment. At December 31, 2012 GM South Africa's goodwill balance was $0.

Impairment Charges

The impairment charges recorded as a result of the initial adoption of ASU 2010-28 and the annual and event-driven goodwill impairment tests in the years ended December 31, 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. The net decreases resulted primarily from the reversal of our deferred tax asset valuation allowances for certain reporting units thus resulting in the recorded amount for deferred taxes exceeding their fair values. The net decreases also resulted from improvements in our nonperformance risk and in our incremental borrowing rates since July 10, 2009. At certain of the testing dates the net decrease was also due to 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. 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 estimated employee benefit obligations. The amount of implied goodwill derived from GM Korea decreased primarily from a reduction in the fair value of certain tax attributes. The amount of implied goodwill derived from GMNA and Holden decreased primarily due to the recorded amount of deferred taxes exceeding the fair values of the tax attributes.

Fair Value Measurements

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 value of our reporting units (excluding GM Financial) include:


•	Our estimated WACC;


•	Our estimated long-term growth rates; and


•	Our estimate of industry volumes 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 any 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 those reporting units failing Step 1 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 utilized for each of our reporting units that required a Step 2 analysis (dollars and vehicles in millions):

_________

(a)

GMNA forecast volumes at December 31, 2012 are 2013 through 2016. GME forecast volumes at January 1, 2011 and March 31, 2011 are 2011 through 2015 and are 2012 through 2016 thereafter. GM Korea forecast volumes are 2012 through 2015, except for at September 30, 2012 which are 2012 through 2016 and December 31, 2012 which are 2013 through 2016. Holden forecast volumes at December 31, 2011 are 2012 through 2015. GM South Africa forecast volumes at October 1, 2012 are 2012 through 2016.


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


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

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

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 application of fresh-start reporting. On the various testing dates noted in the table above, our Step 2 analyses indicated GMNA's, GME's, GM Korea's, GM South Africa's and Holden'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 economic uncertainty continue, our equity price decline on a sustained basis, global economies enter into another recession and industry growth stagnates, or should we release deferred tax asset valuation allowances in certain tax jurisdictions. In these circumstances future goodwill impairments would largely be affected by decreases in the fair value-to-U.S.-GAAP differences that have occurred subsequent to our application of fresh-start reporting, which in the future would primarily occur upon reversal of our remaining deferred tax asset valuation allowances or a decline in the fair value of GM Financial. Any declines would have a negative effect on our earnings that could be material.

Our fair value estimates for annual and 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.

GME Impairment Charges

To determine the estimated fair value of the brand intangible assets, we used the relief from royalty method, which is a form of the income approach. Under this approach, revenue associated with the brand is projected over the expected remaining useful life of the asset. A royalty rate is then applied to estimate the royalty savings. The royalty rate used was based on an analysis of empirical, market-derived royalty rates for guideline intangible assets and a profit split analysis to determine a rate that is economically supported by GME's forecasted profitability. The net after-tax royalty savings are calculated for each year during the remaining economic life of the asset and discounted to present value.

To determine the estimated fair value of the dealer network, we used the cost approach with adjustments in value for the overcapacity of dealers and the sales environment in the region. We determined the fair value to be $0.

The following table summarizes the significant Level 3 inputs for brand intangible assets measurements:

__________


(a)	Represents estimated savings realized from owning the asset or having the royalty-free right to use the asset.


(b)	Represents WACC adjusted for perceived business risks related to these intangible assets.

As a result of our fair value estimates, we adjusted the carrying amount of the GME intangible assets to fair value and recorded asset impairment charges of $1.8 billion at December 31, 2012. These charges were recorded in our GME segment with $1.6 billion recorded in Automotive selling, general and administrative expense and $0.2 billion recorded in Automotive cost of sales. The fair value estimates for GME's intangible assets are based on a valuation premise that assumes the assets' highest and best use are different than their current use due to the overall European macro-economic environment.

The following table summarizes brand intangible assets in GME measured at fair value utilizing Level 3 inputs on a nonrecurring basis (dollars in millions):

Variable Interest Entities [Abstract]

Variable Interest Entities [Text Block]

Variable Interest Entities

Consolidated VIEs

Automotive

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. We consolidated GM Egypt in January 2010 in connection with our adoption of amendments to ASC 810, "Consolidation." GM Egypt, a 31% owned operating entity, assembles and manufactures vehicles. Certain voting and other rights permit us to direct those activities of GM Egypt that most significantly affect its economic performance. At December 31, 2012 and 2011; (1) Total assets of these VIEs were $436 million and $463 million, which were composed of Cash and cash equivalents, Accounts and notes receivables, net, Inventories, and Property, net; and (2) Total liabilities were $254 million and $298 million, which were composed of Accounts payable (principally trade), and Accrued and other liabilities. In the years ended December 31, 2012 and 2011 Total net sales and revenue recorded for these consolidated VIEs were $1.0 billion and $748 million and Net income was $56 million and $61 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.

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

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



	December 31, 2012						December 31, 2011
	GM Korea		HKJV(a)		Total		GM Korea
Short-term debt	$	124	$	104	$	228	$	171
Current derivative	$	18	$	—	$	18	$	44
Long-term debt	$	2	$	120	$	122	$	7

__________


(a)	Consolidated effective September 1, 2012. Refer to Notes 4 and 10 for additional information on the acquisition of HKJV.

In February 2011 we provided a guarantee to a minority shareholder in GM Korea to repurchase the GM Korea mandatorily redeemable 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 years ended December 31, 2012 and 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 17 for additional information on GM Financial's involvement with the SPEs.

Nonconsolidated VIEs

Automotive

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

The following table summarizes the amounts recorded for nonconsolidated VIEs and the related off-balance sheet guarantees and maximum exposure to loss, excluding Ally Financial that is disclosed in Note 27 (dollars in millions):

(a)	Includes debt obligations to Ally Financial of $869 million and $1.1 billion at December 31, 2012 and 2011.


(b)	Net of a $1.1 billion and $1.6 billion discount at December 31, 2012 and 2011.


(c)	The fair value of debt included $4.1 billion and $4.4 billion measured utilizing Level 2 inputs at December 31, 2012 and 2011. The fair value of debt included $1.2 billion and $1.1 billion measured utilizing Level 3 inputs at December 31, 2012 and 2011.


(d)	Includes coupon rates on debt denominated in various foreign currencies and interest free loans.

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 revolving credit facilities, 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.

__________


(a)	Includes wholesale financing of dealer inventory.

Wholesale Financing

Wholesale financing represents arrangements, primarily with Ally Financial, where cash is received in advance of the final sale of vehicles, parts and accessories to our dealers or ultimate consumer. These obligations typically settle through the sale and delivery of our product and generally do not require cash outflows to settle. Balances under these facilities fluctuate period to period based on the volume of vehicles financed.

HCT Notes

As part of the establishment of the HCT to provide retiree healthcare benefits to certain active and retired employees in Canada, we issued notes to the HCT with a fair value of $1.1 billion in October 2011. We recorded a premium of $42 million at issuance. The notes accrue interest at an annual rate of 7.0%. The notes are due in periodic installments through 2018. We may prepay these notes at any time. Refer to Note 18 for additional information on the HCT settlement.

GM Korea Preferred Shares

GM Korea has outstanding non-convertible mandatorily redeemable preferred shares. Dividends accrued at a rate of 2.5% through October 2012 at which time the rate increased to 7.0% and remains in effect through 2017. The mandatorily redeemable preferred shares are redeemable in periodic installments through 2017. In February 2011 we provided a guarantee to repurchase the mandatorily redeemable preferred shares according to the redemption schedule if GM Korea does not have sufficient legally distributable earnings. In December 2012 GM Korea made a payment of $671 million to redeem early a portion of shares that had a carrying amount of $429 million and the difference was recorded as a loss on extinguishment of debt. GM Korea has the option to redeem the remainder of the shares early provided sufficient legally distributable earnings exist.

Secured Revolving Credit Facilities

In November 2012 we entered into two new secured revolving credit facilities with an aggregate borrowing capacity of $11.0 billion. These facilities consist of a three-year, $5.5 billion facility and a five-year, $5.5 billion facility and replaced our previous five-year, $5.0 billion secured revolving credit facility that we entered into in October 2010. Availability under the secured revolving credit facilities is subject to borrowing base restrictions.

The three-year, $5.5 billion facility is available to GM Financial as well as certain wholly-owned domestic and international subsidiaries. The facility includes various sub-limits including a GM Financial borrowing sub-limit of $4.0 billion, a multi-currency borrowing sub-limit of $3.5 billion, a Brazilian Real borrowing sub-limit of approximately $485 million and a letter of credit sub-facility limit of $1.5 billion. We had amounts in use under the letter of credit sub-facility of $207 million at December 31, 2012.

The five-year, $5.5 billion facility allows for borrowings in U.S. Dollars and other currencies and includes a letter of credit sub-limit of $500 million. This facility is not available to GM Financial.

Our obligations under the secured revolving credit facilities are guaranteed by certain of our domestic subsidiaries and by a substantial portion of our domestic assets including accounts receivable, inventory, property, plant and equipment, intellectual property and trademarks, equity interests in certain of our direct domestic subsidiaries as well as up to 65% of the voting equity interests in certain of our direct foreign subsidiaries, in each case, subject to certain exceptions. The collateral securing the secured revolving credit facilities does not include, among other assets, cash, cash equivalents and marketable securities as well as our investments in GM Financial, GM Korea and in our China JVs. If we receive an investment grade corporate rating from two or more of the following credit rating agencies: Fitch Ratings, Moody's Investor Service and Standard & Poor's, we will no longer have to post collateral or provide guarantees from certain domestic subsidiaries under the terms of the facilities. If we fail to maintain an investment grade corporate rating from at least two of the above listed rating agencies, these guarantees will be reinstated.

The secured revolving credit facilities contain representations, warranties and covenants customary for facilities of this nature, including negative covenants restricting incurring liens, consummating mergers or sales of assets and incurring secured indebtedness, and restricting us from making restricted payments, in each case, subject to exceptions and limitations. These restricted payments include, among others, limitations on our ability to pay dividends and purchase our common stock in certain circumstances. The facilities contain minimum liquidity covenants, which require us to maintain at least $4.0 billion in consolidated global liquidity and at least $2.0 billion in consolidated U.S. liquidity.

Interest rates on obligations under the secured revolving credit facilities are based on prevailing per annum interest rates for Eurodollar loans or an alternative base rate plus an applicable margin, in each case, based upon the credit rating assigned to the secured revolving credit facilities or our corporate rating depending on certain criteria.

UST Credit Agreement

In April 2010 we repaid the full outstanding amount under the loan agreement with the United States Department of the Treasury (UST). Amounts repaid under the agreement may not be reborrowed. While we have repaid the loans from the UST in full, certain of the covenants in the UST credit agreement remain, including covenants regarding executive compensation and expense policies. These covenants remain effective until it is determined that we are not a recipient of exceptional financial assistance or their earlier termination.

Gains (Losses) on Extinguishment of Debt

In the year ended December 31, 2012 we prepaid and retired debt obligations with a total carrying amount of $514 million and recorded a loss on extinguishment of debt of $250 million which primarily represented the unamortized debt discount on the GM Korea mandatorily redeemable preferred shares of $242 million. In the year ended December 31, 2011 we prepaid and retired in full debt facilities of $1.0 billion held by certain of our subsidiaries, primarily in GMNA and GMSA, and recorded a gain on these debt facilities of $18 million. In the year ended December 31, 2010 we repaid in full the outstanding amount (together with accreted interest thereon) of the VEBA Note Agreement (VEBA Notes) of $2.8 billion, which resulted in a gain on extinguishment debt of $198 million.

Technical Defaults and Covenant Violations

Several of our loan facilities, including our secured revolving credit facilities require compliance with certain financial and operational covenants as well as regular reporting to lenders, including providing certain subsidiary financial statements. Failure to meet certain of these requirements may result in a covenant violation or an event of default depending on the terms of the agreement. An event of default may allow lenders to declare amounts outstanding under these agreements immediately due and payable, to enforce their interests against collateral pledged under these agreements or restrict our ability to obtain additional borrowings. No technical defaults or covenant violations existed at December 31, 2012.

Total GM Financial debt		$	10,878	$	11,145	$	8,538	$	8,556

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

The estimated fair value of the medium-term note facility is based on observable and unobservable inputs. 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 principal and 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 market value.

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

Credit Facilities

The following table summarizes further details regarding terms and availability of GM Financial's credit facilities at December 31, 2012 (dollars in millions):



	Facility Amount		Advances Outstanding		Assets Pledged		Restricted Cash Pledged(a)
Syndicated warehouse facility(b)	$	2,500	$	—	$	—	$	—
Canada lease warehouse facility(c)	$	803	354		540		3
U.S. lease warehouse facility(d)	$	600	—		—		—
			$	354	$	540	$	3

__________


(a)	These amounts do not include cash collected on finance receivables and leasing related assets pledged of $12 million which is included in Restricted cash and marketable securities.


(b)	In May 2013 when the revolving period ends, and if the facility is not renewed, the outstanding balance will be repaid over time based on the amortization of the receivables pledged until February 2020 when the remaining balance will be due and payable.

(c)

In July 2013 when the revolving period ends, and if the facility is not renewed, the outstanding balance will be repaid over time based on the amortization of the leasing related assets pledged until January 2019 when any remaining balance will be due and payable. Borrowings in the facility are collateralized by leased assets. At December 31, 2012 the facility amount represents Canadian Dollar (CAD) $800 million and the advances outstanding amount represents CAD $353 million.


(d)	In January 2013 GM Financial extended the maturity date of this facility to May 2014. In May 2014 when the revolving period ends, and if the facility is not renewed, the outstanding balance will be repaid over time based on the amortization of the related leased assets pledged until November 2019 when any remaining amount outstanding will be due and payable.

As previously described GM Financial has the ability to borrow against our three-year $5.5 billion secured revolving credit facility.

Credit Facility Covenants

GM Financial is required to hold certain funds in restricted cash accounts to provide additional collateral for borrowings under the credit facilities. GM Financial's funding agreements contain various covenants requiring minimum financial ratios, asset quality and portfolio performance ratios (portfolio net loss and delinquency ratios, and pool level cumulative net loss ratios) as well as limits on deferment levels. Failure to meet any of these covenants could result in an event of default under these agreements. If an event of default occurs under these agreements, the lenders could elect to declare all amounts outstanding under these agreements to be immediately due and payable, enforce their interests against collateral pledged under these agreements, restrict GM Financial's ability to obtain additional borrowings and/or remove GM Financial as servicer. As of December 31, 2012 GM Financial was in compliance with all covenants in its credit facilities.

Securitization Notes Payable

Securitization notes payable represents debt issued by GM Financial in securitization transactions. Debt issuance costs are amortized over the expected term of the securitizations on an effective yield basis. As a result of the acquisition, GM Financial recorded a purchase accounting premium of $133 million that is being amortized over the expected term of the notes. At December 31, 2012 and 2011 unamortized purchase accounting premium of $11 million and $43 million is included in Securitization notes payable.

The following table summarizes securitization notes payable (dollars in millions):

__________


(a)	Maturity dates represent final legal maturity of securitization notes payable. Securitization notes payable are expected to be paid based on amortization of the finance receivables pledged to the trusts.

At the time of securitization of finance receivables, GM Financial is required to pledge assets equal to a specified percentage of the securitization pool to support the securitization transaction. The assets pledged consist of cash deposited to a restricted account and additional receivables delivered to the trust, which create overcollateralization. The securitization transactions require the percentage of assets pledged to support the transaction to increase until a specified level is attained. Excess cash flows generated by the trusts are added to the restricted cash account or used to pay down outstanding debt in the trusts, creating overcollateralization until the targeted percentage level of assets has been reached. Once the targeted percentage level of assets is reached and maintained, excess cash flows generated by the trusts are released to GM Financial as distributions from trusts. As the balance of the securitization pool declines, the amount of pledged assets needed to maintain the required percentage level is reduced. Assets in excess of the required percentage are also released to GM Financial as distributions from trusts.

Senior Notes

In August 2012 GM Financial issued 4.75% senior notes of $1.0 billion which are due in August 2017 with interest payable semiannually. GM Financial intends to use the net proceeds from this offering for general corporate purposes including, but not limited to, acquisitions. The notes are guaranteed by GM Financial's principal operating subsidiary.

In connection with the issuance of these senior notes, GM Financial entered into a registration rights agreement that requires GM Financial to file a registration statement with the Securities and Exchange Commission (SEC) for an exchange offer with respect to the 4.75% senior notes and the subsidiary guaranty. If the registration statement has not been declared effective by the SEC within 365 days from the original issuance of the senior notes or ceases to remain effective, GM Financial will be required to pay the 4.75% senior note holders a maximum amount of $0.50 per week of additional interest per $1,000 of principal during the time the registration statement is not effective, for a period of up to one year.

In June 2011 GM Financial issued 6.75% senior notes of $500 million which are due in June 2018 with interest payable semiannually. In July 2011 proceeds of $71 million from this offering were used to redeem all of GM Financial's outstanding 8.50% senior notes due in 2015. The remaining proceeds are to be used for general corporate purposes.

Pensions and Other Postretirement Benefits

Employee Pension and Other Postretirement Benefit Plans

Defined Benefit Pension Plans

Defined benefit pension plans covering eligible U.S. hourly employees (hired prior to October 15, 2007) and Canadian hourly employees generally provide benefits of negotiated, stated amounts for each year of service and supplemental benefits for employees who retire with 30 years of service before normal retirement age. The benefits provided by the defined benefit pension plans covering eligible U.S. (hired prior to January 1, 2001) and Canadian salaried employees and employees in certain other non-U.S. locations are generally based on years of service and compensation history. Accrual of defined pension benefits ceased on September 30, 2012 for U.S. salaried employees and on December 31, 2012 for Canadian salaried employees. There is also an unfunded nonqualified pension plan covering primarily U.S. executives for service prior to January 1, 2007 and it is based on an “excess plan” for service after that date.

Pension Contributions

The funding policy for qualified defined benefit pension plans is to contribute annually not less than the minimum required by applicable law and regulations or to directly pay benefit payments where appropriate. At December 31, 2012 all legal funding requirements had been met. We expect to contribute $97 million to our U.S. non-qualified plans and $823 million to our non-U.S. pension plans in 2013.

The following table summarizes contributions made to the defined benefit pension plans or direct payments to plan beneficiaries (dollars in millions):



	Years Ended December 31,
	2012		2011		2010
U.S. hourly and salaried	$	2,420	$	1,962	$	4,095
Non-U.S.	855		836		777
Total	$	3,275	$	2,798	$	4,872

We made a voluntary 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.

Other Postretirement Benefit Plans

Certain hourly and salaried defined benefit plans provide postretirement medical, dental, legal service and life insurance to eligible U.S. and Canadian retirees and their eligible dependents. Certain other non-U.S. subsidiaries have postretirement benefit plans, although most non-U.S. employees are covered by government sponsored or administered programs.

OPEB Contributions

The following table summarizes contributions to the U.S. OPEB plans (dollars in millions):



	Years Ended December 31,
	2012		2011		2010
Employer contributions	$	432	$	426	$	651
Plan participants' contributions	4		13		53
Total contributions	$	436	$	439	$	704

For the year ended December 31, 2011 we also contributed $1.9 billion to the independent HCT consisting of restricted cash of $0.8 billion and notes payable of $1.1 billion.

Defined Contribution Plans

We have a defined contribution plan for eligible U.S. salaried employees. This plan provides discretionary matching contributions which we instituted in October 2009. U.S. hourly employees hired after October 1, 2007 also participate in a defined contribution plan. Contributions are also made to certain non-U.S. defined contribution plans.

The following table summarizes our contributions to defined contribution plans (dollars in millions):

Significant Plan Amendments, Benefit Modifications and Related Events

U.S. Salaried Defined Benefit Pension Plan

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

In August 2012 the salaried pension plan was amended to divide the plan to create a new legally separate defined benefit plan primarily for active and terminated vested participants. After the amendment the original salaried pension plan (Retiree Plan) covers the majority of retirees currently receiving payments. As a result of this amendment a remeasurement of the Retiree Plan on August 1, 2012 increased the pension liability and the net pre-tax actuarial loss component of Accumulated other comprehensive loss by $654 million, due primarily to a decrease in the discount rate from 4.21% to 3.37% on a weighted-average basis, partially offset by actual asset returns in excess of expected amounts.

In August 2012 lump-sum distributions of $3.6 billion were made from the Retiree Plan to 12,500 plan participants resulting in a partial plan settlement necessitating a plan remeasurement for the Retiree Plan on August 31, 2012. The settlement resulted in a pre-tax loss of $54 million. The effect on our financial condition was insignificant.

In November and December 2012 the Retiree Plan purchased group annuity contracts from an insurance company and paid a total annuity premium of $25.1 billion and the Retiree Plan settled two other previously guaranteed obligations, with separate insurance companies, totaling $1.9 billion. These agreements unconditionally and irrevocably guarantee the full payment of all annuity payments to the participants in the Retiree Plan and assume all investment risk associated with the assets that were delivered as the annuity contract premiums.

Through these annuity purchase transactions we have settled the remaining obligations of the Retiree Plan in their entirety resulting in a pre-tax settlement loss of $2.5 billion ($2.1 billion after tax) in Automotive cost of sales. The pre-tax loss is composed of existing losses in Accumulated other comprehensive loss of $377 million, and the premium paid to the insurance company of $2.1 billion. The tax benefit of $413 million is composed of the statutory tax benefit of $1.0 billion offset by tax expense of $596 million associated with the removal of prior period income tax allocations between Accumulated other comprehensive loss and Income tax expense (benefit).

In 2012 we provided short-term, interest-free, unsecured loans to the Retiree Plan to provide the plan with incremental liquidity to pay ongoing benefits and administrative costs. In August 2012 we loaned the Retiree Plan $2.0 billion with principal due within 90 days. In the three months ended December 31, 2012 $1.5 billion of the $2.0 billion loan was contributed to the Retiree Plan, $250 million was repaid to us and the remaining $250 million, which had been converted into a new interest-free loan, is due on or before April 15, 2013. In October 2012 we provided a loan of $180 million to the Retiree Plan that was repaid to us in December 2012. At December 31, 2012 $160 million of the remaining $250 million loan was deemed a contribution. Amounts loaned to the Retiree Plan in excess of the ultimate funding requirements will be repaid to us.

Canadian Salaried Defined Benefit Plans

In June 2012 we amended the Canadian salaried pension plan to cease the accrual of additional benefits effective December 31, 2012 and provide active employees a lump-sum distribution option at retirement. The remeasurement, amendments and offsetting curtailment increased the pension liability by $84 million, and resulted in a net decrease in the pre-tax components of Accumulated other comprehensive loss comprising 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 OPEB liability by $28 million and resulted in a net increase in the pre-tax components of Accumulated other comprehensive loss comprising prior service credit of $51 million and net actuarial loss of $23 million.

Canadian HCT

In October 2011 pursuant to a June 2009 agreement between General Motors of Canada Limited (GMCL) and the CAW an independent HCT was implemented to provide retiree healthcare benefits to certain active and retired employees. Concurrent with the implementation of the HCT, GMCL was legally released from all obligations associated with the cost of providing retiree healthcare benefits to CAW retirees and surviving spouses by the class action process and to CAW active employees as of June 8, 2009. We accounted for the related termination of CAW hourly retiree healthcare benefits as a settlement and recorded a gain of $749 million in Automotive cost of sales. The settlement gain represents the difference between the healthcare plan obligation of $3.1 billion (as of the implementation date) and the fair value of the notes and restricted cash contributed totaling $1.9 billion, and recognition of Accumulated other comprehensive loss of $414 million.

Other Remeasurements

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

In September 2011 a plan which provides legal services to U.S. hourly employees and retirees was remeasured as a result of our labor agreement provisions which terminate the plan effective December 31, 2013. The negotiated termination has been accounted for as a negative plan amendment resulting in a decrease in the OPEB liability and a pre-tax increase of $266 million in the prior service credit component of Accumulated other comprehensive loss, which is being amortized through December 31, 2013.

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

Refer to Note 12 for additional information on our Goodwill impairment.

Assumptions

Healthcare Trend Rate

As a result of previous modifications made to healthcare plans, there are no significant uncapped U.S. healthcare plans remaining, therefore, the healthcare cost trend rate does not have a significant effect on our U.S. plans. The implementation of the HCT at October 31, 2011 eliminated significant exposure to changes in the healthcare cost trend rate for non-U.S. plans.



	December 31, 2010
Assumed Healthcare Trend Rates
Initial healthcare cost trend rate	5.6%
Ultimate healthcare cost trend rate	3.4%
Number of years to ultimate trend rate	8

Healthcare trend rate assumptions are determined for inclusion in healthcare OPEB valuation at each remeasurement. The healthcare trend rates are developed using historical cash expenditures and near-term outlook for retiree healthcare. This information is supplemented with information gathered from actuarial based models, information obtained from healthcare providers and known significant events.

The following table summarizes the effect of a one-percentage point change in the assumed healthcare trend rates for non-U.S. plans (dollars in millions):



	Effect on 2011 Aggregate Service and Interest Cost			Effect on December 31, 2010 APBO
Change in Assumption
One percentage point increase	$	31		$	491
One percentage point decrease	$	(25	)	$	(392	)

Investment Strategies and Long-Term Rate of Return

Detailed periodic studies conducted by outside actuaries and an internal asset management group, consisting of an analysis of capital market assumptions and employing Monte-Carlo simulations, are used to determine the long-term strategic mix among asset classes, risk mitigation strategies, and the expected long-term return on asset assumptions for the U.S. pension plans. The U.S. study includes a review of alternative asset allocation and risk mitigation strategies, anticipated future long-term performance of individual asset classes, risks evaluated using standard deviation techniques and correlations among the asset classes that comprise the plans' asset mix. Similar studies are performed for the significant non-U.S. pension plans with the assistance of outside actuaries and asset managers. While the studies incorporate data from recent plan performance and historical returns, the expected long-term return on plan asset assumptions are determined based on long-term, prospective rates of return.

The strategic asset mix and risk mitigation strategies for the plans are tailored specifically for each plan. Individual plans have distinct liabilities, liquidity needs, and regulatory requirements. Consequently, there are different investment policies set by individual plan fiduciaries. Although investment policies and risk mitigation strategies may differ among plans, each investment strategy is considered to be appropriate in the context of the specific factors affecting each plan.

In setting new strategic asset mixes, consideration is given to the likelihood that the selected mixes will effectively fund the projected pension plan liabilities, while aligning with the risk tolerance of the plans' fiduciaries. The strategic asset mixes for U.S. defined benefit pension plans are increasingly designed to satisfy the complementary objectives of reaching fully funded positions (market value of assets equal to or greater than the present value of the liabilities) and mitigating the possibility of a deterioration in funded status.

Derivatives may be used to provide cost effective solutions for rebalancing investment portfolios, increasing or decreasing exposure to various asset classes and for mitigating risks, primarily interest rate and currency risks. Equity and fixed income managers are permitted to utilize derivatives as efficient substitutes for traditional physical securities. Interest rate derivatives may be used to adjust portfolio duration to align with a plan's targeted investment policy. Alternative investment managers are permitted to employ leverage, including through the use of derivatives, which may alter economic exposure.

In January 2013 an investment policy study was completed for the U.S. pension plans taking into account the new plan structures that followed the derisking initiatives and annuity transactions executed during the second half of 2012. The study resulted in new target asset allocations being approved for the U.S. pension plans with resulting changes to the expected long-term return on assets. The weighted-average long-term return on assets decreased from 6.2% at December 31, 2011 to 5.8% due primarily to lower yields on fixed income securities. The U.S. hourly plan assets now represent 91% of the total U.S. pension plan assets compared to 65% at the end of 2011.

The expected long-term return on plan assets used in determining pension expense for non-U.S. plans is determined in a similar manner to the U.S. plans. The rates of 6.2% and 6.5% for the years ended December 31, 2012 and 2011 represent weighted-average rates of all of the funded non-U.S. plans.

Target Allocation Percentages

The following table summarizes the target allocations by asset category for U.S. and non-U.S. defined benefit pension plans:

Investment Fund Strategies

Equity funds include funds that invest in U.S. common and preferred stocks as well as similar equity securities issued by companies incorporated, listed or domiciled in developed and/or emerging markets countries. Certain fund managers may attempt to profit from security mispricing in equity markets. Equity long/short managers typically construct portfolios consisting of long and short positions, which may be determined by a variety of techniques including fundamental, quantitative and technical analysis. Index funds, exchange traded funds and derivatives may be used for hedging purposes to limit exposure to various risk factors.

Fixed income funds include investments in high quality and high yield funds as well as in credit arbitrage funds. High quality fixed income funds invest in U.S. government securities, investment-grade corporate bonds, mortgages and asset-backed securities. High yield fixed income funds invest in U.S. high yield fixed income securities issued by corporations which are rated below investment grade, are unrated but are believed by the investment manager to have similar risk characteristics or are rated investment grade or higher but are priced at yields comparable to securities rated below investment grade and believed to have similar risk characteristics. Credit arbitrage funds invest in a variety of credit and credit-related instruments that allow fund managers to profit from mispricing of these credit instruments. Certain derivatives may be used for hedging purposes by some fixed income fund managers to limit exposure to various risk factors.

Funds of hedge funds include funds that invest in a portfolio of hedge funds. Funds of hedge fund managers typically seek to achieve their objectives by allocating capital across a broad array of funds and/or investment managers.

Global macro funds include funds that enter into leveraged transactions utilizing a variety of equity, fixed income and derivative instruments to benefit from anticipated price movements of stock, interest rates, foreign exchange currencies and physical commodities markets while minimizing downside risk. Global macro managers may invest in a variety of markets to participate in expected market movements.

Multi-strategy funds include funds that invest in broadly diversified portfolios of equity, fixed income and derivative instruments. Certain funds may also employ multiple alternative investment strategies, in combination, such as global macro, event-driven (which seeks to profit from opportunities created by significant transactional events such as spin-offs, mergers and acquisitions, bankruptcy reorganizations, recapitalizations and share buybacks) and relative value (which seeks to take advantage of pricing discrepancies between instruments including equities, debt, options and futures).

Other investment funds generally consist of funds that employ broad-ranging strategies and styles. The objective of such funds is to deliver returns having relatively low volatility and correlation to movements in major equity and bond markets. Funds in this category employ single strategies such as event-driven or relative value.

Private equity and debt investments principally consists of investments in private equity and debt funds. These investments are made to gain exposure to and benefit from long-term equity investments in private companies, including leveraged buy-outs, venture capital and distressed debt strategies.

Real estate investments include funds that invest in entities which are principally engaged in the ownership, acquisition, development, financing, sale and/or management of income-producing real estate properties, both commercial and residential. These funds typically seek long-term growth of capital and current income that is above average relative to public equity funds.

Significant Concentrations of Risk

The pension plans' assets include certain private investment funds, private equity and debt securities, real estate investments and derivative instruments. Investment managers may be unable to quickly sell or redeem some or all of these investments at an amount close or equal to fair value in order to meet a plan's liquidity requirements or to respond to specific events such as deterioration in the creditworthiness of any particular issuer or counterparty.

Illiquid investments held by the plans are generally long-term investments that complement the long-term nature of pension obligations and are not used to fund benefit payments when currently due. Plan management monitors liquidity risk on an ongoing basis and has procedures in place that are designed to maintain flexibility in addressing plan-specific, broader industry and market liquidity events.

The pension plans may invest in financial instruments denominated in foreign currencies and may be exposed to risks that the foreign currency exchange rates might change in a manner that has an adverse effect on the value of the foreign currency denominated assets or liabilities. Forward currency contracts may be used to manage and mitigate foreign currency risk.

The pension plans may invest in fixed income securities for which any change in the relevant interest rates for particular securities might result in an investment manager being unable to secure similar returns upon the maturity or the sale of securities. In addition, changes to prevailing interest rates or changes in expectations of future interest rates might result in an increase or decrease in the fair value of the securities held. Interest rate swaps and other financial derivative instruments may be used to manage interest rate risk.

Counterparty credit risk is the risk that a counterparty to a financial instrument will default on its commitment. Counterparty risk is primarily related to over-the-counter derivative instruments used to manage risk exposures related to interest rates on long-term debt securities and foreign currency exchange rate fluctuations. The risk of default can be influenced by various factors including macro-economic conditions, market liquidity, fiscal and monetary policies and counterparty-specific characteristics and activities. Certain agreements with counterparties employ set-off, collateral support arrangements and other risk mitigating procedures designed to reduce the net exposure to credit risk in the event of counterparty default. Credit policies and processes are in place to manage concentrations of counterparty risk by seeking to undertake transactions with large well-capitalized counterparties and by monitoring the creditworthiness of these counterparties. The majority of derivatives held by the plans at December 31, 2012 were fully collateralized and therefore, the related counterparty credit risk was significantly reduced.

Pension Funding Requirements

We are subject to a variety of U.S. federal rules and regulations, including the Employee Retirement Income Security Act of 1974, as amended and the Pension Protection Act of 2006, which govern the manner in which we fund and administer our pensions for our retired employees and their spouses. In 2012 the U.S. government enacted the Moving Ahead for Progress in the 21st Century Act which allows plan sponsors funding relief for pension plans through the application of higher funding interest rates. As a result, under current economic conditions, we expect no mandatory contributions to our U.S. qualified pension plans for at least five years. The new law does not impact our reported funded status. We have no funding requirements for our U.S. qualified plans in 2013.

We also maintain pension plans for employees in a number of countries outside the U.S. which are subject to local laws and regulations.

Derivative Financial Instruments and Risk Management

Automotive

Derivatives and Hedge Accounting

In accordance with our risk management policy, we enter into a variety of foreign currency exchange rate and commodity derivative contracts to manage our exposure to fluctuations in certain foreign currency exchange rates and commodity prices. At December 31, 2012 and 2011 our derivative instruments consisted primarily of forward contracts and options, none of which were designated in hedging relationships. We manage our counterparty credit risk by monitoring the credit ratings of our counterparties and by requiring them to post collateral in certain circumstances. Agreements are entered into with counterparties that allow the set-off of certain exposures in order to manage the risk. Certain of our agreements with counterparties require that we provide cash collateral. At December 31, 2012 and 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.

Fair Value of Derivatives

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

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

We 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 utilizing 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 the 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 to 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 December 31, 2012:



	Valuation Technique	Significant Unobservable Input	Metric
Commodity	Discounted cash flow	Coal forward price per ton in Euro(a)	€93.09
		Heavy fuel oil forward price per ton in Euro(a)	€562.51
		Supplier nonperformance risk (average)	2.44%
Embedded	Discounted cash flow	Average Euro/TRY forward exchange rate(b)	€2.72
		Volume commitment and vehicle mix in Euro(c)	€909 million

__________


(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.

Fair Value Measurements on a Recurring Basis Using Level 3 Inputs

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

Other Derivatives

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.

In connection with our investment in New Delphi, which we accounted for using the equity method, we recorded our share of New Delphi's other comprehensive income (loss) in Accumulated other comprehensive income. In the three months ended March 31, 2011 we recorded cash flow hedging gains of $13 million and in the year ended December 31, 2010 we recorded cash flow hedging losses of $22 million related to our share of New Delphi's hedging gains and losses. In March 2011 we sold our interests in New Delphi. As a result previously recorded cash flow hedging losses of $10 million in Accumulated other comprehensive loss were reclassified to earnings and recorded in the gain on sale of New Delphi. Refer to Note 10 for additional information on the sale of New Delphi.

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 $775 million and $2.0 billion at December 31, 2012 and 2011. GM Financial had interest rate swaps and caps in liability positions with notional amounts of $775 million and $2.0 billion at December 31, 2012 and 2011. The fair value of these derivative financial instruments was insignificant.

Credit Risk Related Contingent Features

Under the terms of the derivative financial instruments, GM Financial is required to pledge certain funds to be held in restricted cash accounts as collateral for the outstanding derivative transactions. At December 31, 2012 and 2011 these restricted cash accounts totaled $4 million and $36 million and were recorded in Restricted cash and marketable securities.

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

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 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 27 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 2013 through 2017 or are ongoing, or upon the occurrence of specific events.

In some instances certain assets of the party whose debt or performance we have guaranteed may offset, to some degree, the cost of the guarantee. The offset of certain of our payables to guaranteed parties may also offset certain guarantees, if triggered. At December 31, 2012 any proceeds we would receive from collateral would be approximately $60 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.

Credit Card Programs

Credit card programs offer rebates that can be applied primarily against the purchase or lease of our vehicles.

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 December 31, 2012 we estimate the remediation losses could range from $130 million to $250 million.

Product Liability

With respect to product liability claims involving our and Old GM's products, we believe that any judgment against us for actual damages will be adequately covered by our recorded accruals and, where applicable, excess liability insurance coverage. Although punitive damages are claimed in some of these lawsuits and such claims are inherently unpredictable, accruals incorporate historic experience with these types of claims. Liabilities have been recorded for the expected cost of all known product liability claims plus an estimate of the expected cost for product liability claims that have already been incurred and are expected to be filed in the future for which we are self-insured. These amounts were recorded in Accrued liabilities and Other liabilities and deferred income taxes.

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

Other Litigation-Related Liability and Tax Administrative Matters

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

With regard to the litigation matters discussed in the previous paragraph, reserves have been established for matters in which we believe that losses are probable and can be reasonably estimated, the majority of which are associated with 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 $400 million to $600 million. Some of the matters may involve compensatory, punitive or other treble damage claims, environmental remediation programs or sanctions that, if granted, could require us to pay damages or make other expenditures in amounts that could not be reasonably estimated at December 31, 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.

GM Korea Wage Litigation

Commencing on or about September 29, 2010 current and former hourly employees of GM Korea filed seven separate group actions in the Incheon District Court in Incheon, Korea. The cases, which in the aggregate involve more than 10,000 employees, allege that GM Korea failed to include certain allowances in its calculation of Ordinary Wages due under the Presidential Decree of the Korean Labor Standards Act. On November 23, 2012 the Seoul High Court (an intermediate level appellate court) issued a decision affirming a decision of the Incheon District Court in a case involving five GM Korea employees which was contrary to GM Korea's position in all of these cases. Although GM Korea believes the decision of the Seoul High Court is incorrect and intends to appeal to the Supreme Court of the Republic of Korea we have increased our accrual in the three months ended December 31, 2012 by 564 billion Korean Won (equivalent to $525 million) to 746 billion Korean Won (equivalent to $697 million) in connection with these cases. In the year ended December 31, 2012 we recorded 616 billion Korean Won (equivalent to $573 million) in Automotive cost of sales (77% of which is reflected in our Net income attributable to stockholders based on our ownership interest in GM Korea). We do not believe we have any reasonably possible exposure in excess of the amount of the accrual. Both the scope of claims asserted and GM Korea's assessment of any or all of individual claim elements may change if new information becomes available.

GMCL Dealers' Claim

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

UAW Claim

On April 6, 2010 the 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. We believe that the claim is without merit and we have no accrual relating to this litigation. We believe the UAW's claim is barred by the 2009 UAW Retiree Settlement Agreement approved by the U.S. Bankruptcy Court for the Southern District of New York (Bankruptcy Court). We also maintain that Delphi Corporation's bankruptcy plan of reorganization did not fulfill the applicable conditions of the relevant agreement and therefore payment would not be due even in the absence of the 2009 UAW Retiree Settlement Agreement.

Nova Scotia Claims Litigation

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

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

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

Although we believe the positions taken by the GUC Trust are without merit, it is reasonably possible that the Bankruptcy Court will issue rulings adverse to our interest in the Nova Scotia Claims Litigation. Such rulings could lead to subsequent claims which, although we believe would be without merit, could adversely impact GMCL's compromise of the intercompany loans. It is impossible to estimate the reasonably possible loss which would depend upon a variety of factors including the outcome of additional litigation. However the compromise of the intercompany loans for CAD $399 million resulted in a savings to GMCL of CAD $935 million (equivalent to $940 million) which we believe represents a reasonable estimate of the approximate amount of the maximum reasonably possible loss.

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 $186 million and $209 million at December 31, 2012 and 2011 was pledged as collateral under the agreement. Through December 31, 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.

Asset Retirement Obligations

Asset retirement obligations relate to legal obligations associated with retirement of tangible long-lived assets that result from acquisition, construction, development or normal operation of a long-lived asset. An analysis is performed of such obligations associated with all real property owned or leased, including facilities, warehouses and offices. Estimates of conditional asset retirement obligations relate, in the case of owned properties, to costs estimated to be necessary for the legally required removal or remediation of various regulated materials, primarily asbestos. Asbestos abatement was estimated using site-specific surveys where available and a per square foot estimate where surveys were unavailable. For leased properties such obligations relate to the estimated cost of contractually required property restoration. At December 31, 2012 and 2011 accruals for asset retirement obligations were $116 million and $99 million.

__________

(a)

In the year ended December 31, 2012 the difference between the change in the valuation allowance and the income tax benefit associated with the valuation allowance release is due primarily to the establishment of deferred tax liabilities related to state deferred tax assets. In the year ended December 31, 2011 we recorded an adjustment to the debt cancellation income that resulted from the 363 Sale. The adjustment resulted in a $2.1 billion increase in valuation allowances related to U.S. federal and state tax attributes.

At December 31, 2012, as a result of sustained profitability in the U.S. and Canada evidenced by three years of earnings and the completion of our near- and medium-term business plans in the three months ended December 31, 2012 that forecast continuing profitability, we determined it was more likely than not future earnings will be sufficient to realize deferred tax assets in these two jurisdictions. Accordingly we reversed most of the U.S. and Canadian valuation allowances resulting in non-cash income tax benefits of $33.2 billion and $3.1 billion. We retained valuation allowances of $2.3 billion against deferred tax assets in the U.S. and Canada related primarily to capital loss tax attributes and state operating loss carryforwards which we continue to believe do not meet the more likely than not threshold for releasing the valuation allowance. We retained additional valuation allowances of $8.7 billion against non-U.S. deferred tax assets, primarily related to GME and South Korea business units with losses.

At December 31, 2011, as a result of sustained profitability in Australia, we released the valuation allowance against deferred tax assets. The reduction in the valuation allowance resulted in a non-cash income tax benefit of $502 million.

Uncertain Tax Positions

Other Matters

The ability to utilize certain of the U.S. tax attributes in future tax periods could be limited by Section 382 of the Internal Revenue Code. On November 1, 2010 we amended our certificate of incorporation to minimize the likelihood of an ownership change occurring for Section 382 purposes. We have net operating loss carryforwards in Germany through November 30, 2009 that, as a result of reorganizations that took place in 2008 and 2009, were not recorded as deferred tax assets. Depending on the outcome of European court decisions these loss carryforwards may be available to reduce future taxable income in Germany. In Australia we have net operating loss carryforwards which are subject to meeting a “Same Business Test” requirement that we assess on a quarterly basis.

Income tax returns are filed in multiple jurisdictions and are subject to examination by taxing authorities throughout the world. We have open tax years from 2002 to 2012 with various significant tax jurisdictions. These open years contain matters that could be subject to differing interpretations of applicable tax laws and regulations as they relate to the amount, character, timing or inclusion of revenue and expenses or the sustainability of income tax credits for a given audit cycle. Given the global nature of our operations there is a risk that transfer pricing disputes may arise.

In the U.S. we have continuing responsibility for Old GM's open tax years. Old GM's federal income tax returns through the date of the 363 Sale have been audited by the Internal Revenue Service. Audit closure in January 2013 of Old GM's 2007, 2008 and 2009 federal income tax returns will result in no change to the amount of unrecognized tax benefits. The audit of our 2009 federal income tax return was concluded in January 2013 and will result in no change to the amount of unrecognized tax benefits. In January 2013 the U.S. Congress enacted federal income tax legislation including an extension of the research credit for tax years 2012 and 2013. As a result, in the three months ending March 31, 2013, we will record an income tax benefit related to the 2012 research credit of approximately $160 million.

In May 2012 a Brazilian income tax assessment was issued related to the 2007 tax year totaling $181 million including tax, interest and penalties. We believe we have adequate reserves established. Proceedings may require that we deposit escrow funds in the future.

In March 2012 a Mexican income tax audit covering the 2004 tax year was concluded and an assessment, adjusted for inflation, of $136 million including tax, interest and penalties was issued. The total 2002, 2003 and 2004 assessments, adjusted for inflation, at December 31, 2012 including tax, interest and penalties is $309 million. We believe we have adequate reserves established. Payment of any assessment is suspended during the proceedings through U.S. and Mexican competent authorities.

In the year ended December 31, 2011 certain issues were resolved relating to uncertain tax positions in jurisdictions which had full valuation allowances. The resolution of these matters resulted in a $2.7 billion reduction to gross uncertain positions. No tax benefit was recognized with respect to these reductions because the entities were in full valuation allowance jurisdictions or the amounts were reserved in a prior period.

In June 2011 we settled a Brazilian income tax matter for $241 million that was reserved and disclosed in a prior period.

In November 2010 an agreement was reached with the Canadian government to resolve various income tax matters in the years 2003 through 2009. In the three months ended December 31, 2010 this resolution resulted in a tax benefit of $140 million including interest.

At December 31, 2012 it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits in the next twelve months.

- Definition

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

Restructuring and Related Activities Disclosure [Text Block]

Restructuring and Other Initiatives

We have previously executed various restructuring and other initiatives, and we plan to execute additional initiatives in the future, if necessary, in order to align manufacturing capacity and other costs with prevailing global automotive production and to improve the utilization of remaining facilities. To the extent these programs involve voluntary separations, no liabilities are generally recorded until offers to employees are accepted. If employees are involuntarily terminated, a liability is generally recorded at the communication date. Related charges are recorded in Automotive cost of sales and Automotive selling, general and administrative expense.

The following table summarizes the reserves related to restructuring and other initiatives (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 $356 million, $376 million and $363 million at December 31, 2012, 2011 and 2010 for GMNA, primarily relate to postemployment benefits to be paid.

Year Ended December 31, 2012

GMNA recorded charges, interest accretion and other and revisions to estimates that increased the reserves by $62 million. The $62 million includes charges for cash severance incentive programs for skilled trade U.S. hourly employees, partially offset by increased production capacity utilization in Canada.

GMNA recorded charges of $90 million in connection with our 2011 UAW labor agreement that included cash severance incentive programs which were completed at March 31, 2012 for skilled trade U.S. hourly employees. A total of 1,400 skilled trade U.S. hourly employees participated in these programs at a total cost of $99 million and was recorded upon irrevocable acceptances by both parties.

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

GME recorded charges, interest accretion and other of $254 million for previously announced separation and early retirement programs. Through December 31, 2012 the active separation programs related to Germany and the United Kingdom had a total cost of $400 million and had affected a total of 2,550 employees, of which $310 million related to a program initiated in Germany in 2010. This program was essentially completed in 2012. We expect to complete the active programs in 2013 and incur an additional $200 million, which will affect an additional 700 employees.

GMIO recorded charges, interest accretion and other related to voluntary separation programs primarily in Korea and Australia. Through December 31, 2012 these programs had a total cost of $69 million which affected 650 employees. We expect to complete the programs in GMIO in 2013 and incur up to an additional $40 million, which will affect up to an additional 200 employees.

GMSA recorded charges of $87 million for employee separation costs related to a separation program in Brazil.

Year Ended December 31, 2011

GMNA recorded charges, interest accretion and other and revisions to estimates primarily related to special attrition programs for skilled trade U.S. hourly employees, service cost for hourly layoff benefits and Canadian restructuring activities.

GME recorded charges, interest accretion and other for separation programs primarily related to previously announced programs in Germany. Restructuring and early retirement programs in Spain, the U.K. and Belgium were essentially completed in 2010 and we also initiated a program in Germany in 2010. Through December 31, 2011 these programs had a total cost of $1.1 billion and affected a total of 6,700 employees and included the December 2010 closure of the Antwerp, Belgium facility.

GMSA recorded charges, interest accretion and other for separation programs primarily related to the voluntary separation program in Brazil implemented in the three months ended December 31, 2011. A total of 900 employees in Brazil participated in the separation program at a total cost of $74 million.

Year Ended December 31, 2010

GMNA recorded charges, interest accretion and other, and revisions to estimates primarily related to increased production capacity utilization, which resulted in the recall of idled employees to fill added shifts at multiple U.S. production sites and revisions to productivity initiatives, partially offset by Canadian restructuring activities.

GME recorded charges, interest accretion and other, and revisions to estimates for separation programs primarily related to the following initiatives:

•Separation charges of $527 million related to the closure of the Antwerp, Belgium facility which affected 2,600 employees.


•	Separation charges of $63 million related to separation/layoff plans and an early retirement plan in Spain which ultimately affected 1,200 employees.

•Separation charges of $31 million related to a voluntary separation program in the United Kingdom.


•	Separation charges of $95 million and interest accretion and other of $104 million related to a voluntary separation program 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.

Stockholders’ Equity and Noncontrolling Interests

Preferred Stock

The following table summarizes significant features relating to our preferred stock (dollars in millions, except for per share amounts):



	Liquidation Preference Per Share		Dividend Rate Per Annum		Dividends Paid
					Years Ended December 31,
					2012		2011		2010
Series A Preferred Stock	$	25.00	9.00	%	$	621	$	621	$	810
Series B Preferred Stock	$	50.00	4.75	%	$	238	$	243	$	—

Series A Preferred Stock

The Series A Preferred Stock ranks senior with respect to liquidation preference and dividend rights to our common stock and Series B Preferred Stock and any other class or series of stock that we may issue. In the event of any voluntary or involuntary liquidation, dissolution or winding-up of our affairs, a holder of Series A Preferred Stock will be entitled to be paid, before any distribution or payment may be made to any holders of common stock or Series B Preferred Stock, the liquidation amount and the amount of any accrued and unpaid dividends, if any, whether or not declared, prior to such distribution or payment date. On or after December 31, 2014, the Series A Preferred Stock may be redeemed, in whole or in part, for cash at a price per share equal to the $25.00 per share liquidation amount, plus any accrued and unpaid dividends. Upon a redemption or purchase of any or all Series A Preferred Stock, the difference, if any, between the recorded amount of the Series A Preferred Stock being redeemed or purchased and the consideration paid would be recorded as a charge to Net income attributable to common stockholders. If all of the Series A Preferred Stock were to be redeemed or purchased at its par value, the amount of the charge would be $1.4 billion.

In December 2010 we purchased 84 million shares of Series A Preferred Stock, held by the UST, at a price equal to 102% of the aggregate liquidation amount, for $2.1 billion. The purchase of the UST's Series A Preferred Stock resulted in a charge of $677 million recorded in Cash dividends paid on Series A Preferred Stock and cumulative dividends on Series B Preferred Stock and charge related to purchase of Series A Preferred Stock.

Series B Preferred Stock

The Series B Preferred Stock, with respect to dividend rights and rights upon our liquidation, winding-up or dissolution, ranks: (1) senior to our common stock and to each other class of capital stock or series of preferred stock the terms of which do not expressly provide that such class or series ranks senior to, or on a parity with, the Series B Preferred Stock; (2) on a parity with any class of capital stock or series of preferred stock the terms of which expressly provide that such class or series will rank on a parity with the Series B Preferred Stock; and (3) junior to our Series A Preferred Stock and to each class of capital stock or series of preferred stock the terms of which expressly provide that such class or series will rank senior to the Series B Preferred Stock.

Each share of the Series B Preferred Stock, unless previously converted, will automatically convert on December 1, 2013 into shares of our common stock. The number of shares of our common stock issuable upon mandatory conversion of each share of Series B Preferred Stock is determined based on the applicable market value of our common stock subject to anti-dilution adjustments and accumulated and unpaid dividends. The applicable market value of our common stock is the average of the closing prices of our common stock over the 40 consecutive trading day period ending on the third trading day immediately preceding the mandatory conversion date. Holders of the Series B Preferred Stock have the right to convert their shares at any time prior to the mandatory conversion date at a conversion ratio of 1.2626 shares of our common stock for each share of the Series B Preferred Stock that is optionally converted, subject to anti-dilution, make-whole and other adjustments.

If the applicable market value of our common stock upon mandatory conversion falls within a range of $33.00-$39.60 per common share, the holder receives a variable number of shares of our common stock with a value equal to the liquidation preference plus accumulated dividends. If the applicable market value is not within this range, there is a fixed conversion ratio equaling 1.2626 shares of common stock for each share of Series B Preferred Stock when the applicable market value of our common stock is greater than $39.60, and 1.5152 shares of common stock for each share of Series B Preferred Stock when the applicable market value of our common stock is less than $33.00. The fixed conversion ratios will be adjusted for events that would otherwise dilute a Series B Preferred Stockholder's interest.

In the three months ended December 31, 2012, holders of our Series B Preferred Stock converted 11,204 shares into 14,145 shares of common stock.

Common Stock

Holders of our common stock are entitled to dividends at the sole discretion of our Board of Directors. However, the terms of the Series A Preferred Stock and Series B Preferred Stock prohibit, subject to exceptions, the payment of dividends on our common stock unless all accrued and unpaid dividends on the Series A Preferred Stock and Series B Preferred Stock are paid in full. Holders of common stock are entitled to one vote per share on all matters submitted to our stockholders for a vote. The liquidation rights of holders of our common stock are secondary to the payment or provision for payment of all our debts and liabilities and to holders of our Series A Preferred Stock and Series B Preferred Stock, if any such shares are then outstanding.

In the year ended December 31, 2011 we issued 61 million shares of common stock to the U.S. hourly and salaried pension plans, 3,500,000 shares for exercised warrants and 500,000 shares for the settlement of salary and other restricted stock awards.

In December 2012 we purchased 200 million shares of our common stock from the UST at a price of $27.50 per share for a total of $5.5 billion. The purchase price represented a premium to the prior day's closing price of $25.49. We allocated the purchase price between a direct reduction to shareholder's equity of $5.1 billion and a charge to earnings of $402 million representing the premium. This premium was recorded in Other automotive expenses, net. These shares were retired by the Board and returned to authorized but unissued status. In the year ended December 31, 2012 we issued 1,300,000 shares of common stock for the settlement of restricted stock and salary stock awards and 400,000 shares for exercised warrants.

The UST agreed to irrevocably waive certain of its rights under the stockholders agreement by and among us and certain other stockholders and covenants under the UST Credit Agreement as part of this agreement. These rights and covenants included, among other items, a reduction in certain reporting requirements and a release from the vitality commitment, which contained certain manufacturing volume requirements.

Warrants

In connection with the 363 Sale we issued two tranches of warrants, each to acquire 136 million shares of common stock, to MLC which have all been distributed to creditors of Old GM and to the GUC Trust by MLC and one tranche of warrants to acquire 46 million shares of common stock to the New VEBA. The first tranche of MLC warrants is exercisable at any time prior to July 10, 2016 at an exercise price of $10.00 per share and the second tranche of MLC warrants is exercisable at any time prior to July 10, 2019 at an exercise price of $18.33 per share. The New VEBA warrants are exercisable at any time prior to December 31, 2015 at an exercise price of $42.31 per share. 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. The number of shares of common stock underlying each of the warrants and the per share exercise price are subject to adjustment as a result of certain events, including stock splits, reverse stock splits and stock dividends. The outstanding balance of warrants at December 31, 2012 and 2011 was 313 million.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings Per Share

In the years ended December 31, 2012 and 2011 we were required to use the two-class method for calculating earnings per share, as further discussed below, as the applicable market value of our common stock was below $33.00 per common share in the periods ended December 31, 2012 and 2011.

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

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

__________


(a)	Includes earned but undeclared dividends of $26 million, $26 million and $26 million on our Series A Preferred Stock and $20 million, $20 million and $25 million on our Series B Preferred Stock in the years ended December 31, 2012, 2011 and 2010.

(b)

Includes cumulative dividends on preferred stock of $859 million and earnings of $470 million that have been allocated to the Series B Preferred Stock holders in the year ended December 31, 2012; includes cumulative dividends on preferred stock of $859 million and earnings of $746 million that have been allocated to the Series B Preferred Stock holders in the year ended December 31, 2011; and cumulative dividends on preferred stock of $827 million and a charge related to the purchase of Series A Preferred Stock of $677 million in the year ended December 31, 2010.

(c)

Includes cumulative dividends on preferred stock of $859 million and earnings of $442 million that have been allocated to the Series B Preferred Stock holders in the year ended December 31, 2012; includes cumulative dividends on preferred stock of $859 million and earnings of $693 million that have been allocated to the Series B Preferred Stock holders in the year ended December 31, 2011; and cumulative dividends on preferred stock of $827 million and a charge related to the purchase of Series A Preferred Stock of $677 million in the year ended December 31, 2010.

Years Ended December 31, 2012 and 2011

Holders of the Series B Preferred Stock have a right to participate in our undistributed earnings because a dividend, if declared, would result in a transfer of value to the holder through an adjustment to the fixed conversion ratios through various anti-dilution provisions. Based on the nature of the Series B Preferred Stock and the nature of these anti-dilution provisions, we have concluded that the Series B Preferred Stock is a participating security and, as such, the application of the two-class method for computing earnings per share is required when the applicable market value of our common stock is below $33.00 or above $39.60 per share. For purposes of calculating earnings per share, the applicable market value is calculated as the average of the closing prices of our common stock over the 40 consecutive trading day period ending on the third trading day immediately preceding the date of our financial statements. The calculation of the applicable market value at the date of our financial statements will apply to the full year, irrespective of the applicable market value computed during the prior quarters of the current year.

We applied the two-class method to calculate basic earnings per share and the more dilutive of the two-class or the if-converted method to calculate diluted earnings per share in the years ended December 31, 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.

The application of the two-class method resulted in an allocation of undistributed earnings to our Series B Preferred Stock holders and, accordingly, 152 million common stock equivalents from the assumed conversion of the Series B Preferred Stock are not considered outstanding for purposes of determining the weighted-average common shares outstanding in the computation of diluted earnings per share in the years December 31, 2012 and 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 December 31, 2012 and 2011, of which 46 million shares were not included in each year's 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 104 million and 130 million dilutive shares in the years ended December 31, 2012 and 2011.

Diluted earnings per share included the effect of 15 million and 13 million unvested RSUs granted to certain global executives in the years ended December 31, 2012 and 2011.

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 considered outstanding for earnings per share purposes beginning in July 2011.

Year Ended December 31, 2010

Warrants to purchase 318 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 106 million dilutive shares.

Diluted earnings per share included the effect of 11 million unvested RSUs granted to certain global executives. The dilutive effect of the RSUs was included only for the period subsequent to our public offering as the RSUs prior were accounted for as liability awards prior to that date.

Stock Incentive Plans (Notes)

Stock Incentive Plans [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

Stock Incentive Plans

Our stock incentive plans consist of the 2009 Long-Term Incentive Plan and the Salary Stock Plan. Both plans are administered by the Executive Compensation Committee of our Board of Directors. The aggregate number of shares with respect to which awards may be granted under these amended plans shall not exceed 75 million.

Long-Term Incentive Plan

We granted 7 million, 5 million and 15 million RSUs in the years ended December 31, 2012, 2011 and 2010. These awards granted either cliff vest or ratably vest generally over a three-year service period, as defined in the terms of each award. Our policy is to issue new shares upon settlement of RSUs.

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

The 2011 awards granted to the Top 25 highest compensated employees will settle three years from the grant date in 25% increments consistent with the terms of the 2009 Long-Term Incentive Plan. The awards for the Next 75 highest compensated employees will settle 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.

The 2010 awards granted to the Top 25 highest compensated employees will settle three years from the grant date in 25% increments consistent with the terms of the 2009 Long-Term Incentive Plan. The awards for the non-top 25 highest compensated employees will settle after three years.

Retirement eligible participants that are non-Top 25 highest compensated employees who retire during the service period will retain and vest in a pro-rata portion of RSUs earned. The vested award will be payable on the settlement date.

Salary Stock Plan

In the years ended December 31, 2012, 2011 and 2010 a portion of each participant's salary was accrued on each salary payment date and converted to RSUs on a quarterly basis. In March 2012 we amended the plan to provide for cash settlement of awards instead of issuing new shares. 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.

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 December 31, 2011	22.5		$	23.01	1.1
Granted	9.1		$	25.10
Settled	(3.2	)	$	27.71
Forfeited or expired	(1.5	)	$	24.42
RSUs outstanding at December 31, 2012	26.9		$	23.06	0.7
RSUs unvested and expected to vest at December 31, 2012	16.2		$	23.49	1.0
RSUs vested and payable at December 31, 2012	10.3		$	22.27	—
RSUs granted in the year ended December 31, 2011			$	31.18
RSUs granted in the year ended December 31, 2010			$	19.17

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



	Years Ended December 31,
	2012		2011		2010
Compensation expense	$	302	$	233	$	235
Income tax benefit	$	100	$	—	$	—

At December 31, 2012 the total unrecognized compensation expense for nonvested equity awards granted was $185 million. This expense is expected to be recorded over a weighted-average period of one year.

The total fair value of RSUs vested in the years ended December 31, 2012, 2011 and 2010 was $141 million, $105 million and $78 million.

In the years ended December 31, 2012, 2011 and 2010 total payments for 1.6 million, 456,000 and 292,000 RSUs settled under stock incentive plans were $36 million, $14 million and $5 million.

Marketing Incentives and Operating Lease Residuals

Under an interest rate support program, we pay an amount at the time of lease or retail contract origination to adjust the interest rate in the retail contract or implicit in the lease below Ally Financial's standard interest rate. The amount paid at contract origination represents the present value of the difference between the customer's contractual rate and Ally Financial's standard rate for a given program.

Under a residual support program, a customer's contract residual value is adjusted above Ally Financial's standard residual value. We reimburse Ally Financial to the extent sales proceeds are less than the customer's contract residual value, limited to Ally Financial's standard residual value. The residual support amount owed is calculated at contract termination and, in cases where the amount differs from the expected amount paid at contract origination, the difference is paid to or paid by Ally Financial.

Under a risk-sharing arrangement, residual losses are shared equally with Ally Financial to the extent remarketing proceeds are below Ally Financial's standard residual value (limited to a floor).

Under a capitalized cost reduction program, we pay an amount at the time of lease or retail contract origination to reduce the principal amount implicit in the lease or retail contract below the standard manufacturers' suggested retail price.

Under a lease pull-ahead program, a customer is encouraged to terminate their lease early and buy or lease a new GM vehicle. Ally Financial waives the customer's remaining payment obligation under their current lease and Ally Financial is compensated for any foregone revenue from the waived payments. Since these programs generally accelerate the resale of the vehicle, the proceeds are typically higher than if the vehicle had been sold at contract maturity. The reimbursement to Ally Financial for the foregone payments is reduced by the amount of this benefit.

Exclusivity Arrangements

We have entered into exclusivity agreements with Ally Financial whereby: (1) for a two-year period, retail financing incentive programs can be offered through a third-party financing source under certain specified circumstances, and after such two-year period beginning in January 2011 through December 2013 any such incentive programs can be offered on a graduated basis through third-parties on a non-exclusive basis, or if Ally Financial matches the rates offered by such third-party on a side-by-side basis with Ally Financial; (2) Ally Financial has no obligation to provide financing; and (3) Ally Financial has no targets against which it could be assessed penalties. After December 31, 2013 we will no longer have any restrictions or limitations on our ability to offer retail financing incentive programs through any third-party financing source as a result of agreements with Ally Financial.

Contractual Exposure Limit

We have an agreement with Ally Financial that limits certain unsecured obligations arising from service agreements to Ally Financial to $1.5 billion and limits the sum of maximum unsecured exposure and maximum secured exposure to the greater of $3.0 billion or 15% of Ally Financial's capital from and after December 30, 2010.

Vehicle Repurchase Obligations

Our agreement with Ally Financial requires the repurchase of Ally Financial financed inventory invoiced to dealers with limited exclusions, in the event of a qualifying voluntary or involuntary termination of the dealer's sales and service agreement. The repurchase obligation ended in August 2010 for vehicles invoiced through August 2009, ended in August 2011 for vehicles invoiced through August 2010, ended in August 2012 for vehicles invoiced through August 2011, ends in August 2013 for vehicles invoiced through August 2012 and ends in August 2014 for vehicles invoiced through August 2013.

The maximum potential amount of future payments required to be made to Ally Financial under this guarantee is based on the repurchase value of total eligible vehicles financed by Ally Financial in dealer stock. If vehicles are required to be repurchased under this arrangement, the total exposure would be reduced to the extent vehicles are able to be resold to another dealer. The fair value of the guarantee, which considers the likelihood of dealers terminating and estimated loss exposure for ultimate disposition of vehicles, was recorded as a reduction of revenue.

Ally Financial Common and Preferred Stock

In December 2010 the UST agreed to convert 110 million shares of preferred securities into 532,000 shares of common stock. This resulted in the dilution of our investment in Ally Financial common stock from 16.6% to 9.9%, of which 4.0% was held directly and 5.9% was held indirectly through an independent trust. In May 2011 we transferred the 4.0% of shares we owned directly to the independent trust. In December 2011 in response to a letter from the trustee requesting that the life of the trust be extended, the Federal Reserve agreed to extend the trust from December 2011 to December 2013. Pursuant to previous commitments to reduce influence over and ownership in Ally Financial, the trustee, who is independent of us, has the sole authority to vote and is required to dispose of all Ally Financial common stock held in the trust by December 24, 2013. We can cause the trustee to return any Ally Financial common stock to us to hold directly, so long as our directly held voting and total common equity interests remain below 10.0%. At December 31, 2012 and 2011 our equity ownership in Ally Financial was 9.9%.

Fair Value of Ally Financial Common Stock

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 December 31, 2012 and 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. 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 UST 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):

Common stock
Carrying amount	$	399	$	403
Fair value	$	1,268	$	403

Segment Reporting

12 Months Ended

Dec. 31, 2012

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 December 31, 2012 we also had equity ownership stakes directly or indirectly in entities through various regional subsidiaries, including GM Korea, SGM, SGMS, SGMW, FAW-GM and HKJV. These companies design, manufacture and market vehicles under the following brands:



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

Nonsegment operations are classified as Corporate. Corporate includes an investment 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 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 (Policies)	12 Months Ended
Basis Of Presentation (Policies)	Dec. 31, 2012
Basis of Presentation [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include our accounts and those of our subsidiaries that we control due to ownership of a majority voting interest and our consolidated variable interest entities (VIEs) of which we are the primary beneficiary. We continually evaluate our involvement with VIEs to determine whether we have variable interests and are the primary beneficiary of the VIE. When these criteria are met, we are required to consolidate the VIE. Our share of earnings or losses of nonconsolidated affiliates is included in our consolidated operating results using the equity method of accounting when we are able to exercise significant influence over the operating and financial decisions of the affiliate. We use the cost method of accounting if we are not able to exercise significant influence over the operating and financial decisions of the affiliate. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates, Policy	Use of Estimates in the Preparation of the Financial Statements The 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

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

- 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.
