Nature Of Operations	Dec. 31, 2011
Nature of Operations [Abstract]
Nature Of Operations	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 (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,” and is the successor entity solely for accounting and financial reporting purposes (Successor). General Motors Corporation is sometimes referred to in these consolidated financial statements, for the periods on or before July 9, 2009, as “Old GM.” Prior to July 10, 2009 Old GM operated the business of the Company, and pursuant to the agreement with the Securities and Exchange Commission (SEC), as described in a no-action letter issued to Old GM by the SEC Staff on July 9, 2009 regarding our filing requirements and those of Motors Liquidation Company (MLC), the accompanying consolidated financial statements include the financial statements and related information of Old GM as it is the predecessor entity solely for accounting and financial reporting purposes (Predecessor). On July 10, 2009 in connection with the 363 Sale, General Motors Corporation changed its name to Motors Liquidation Company. On December 15, 2011 MLC was dissolved and the Motors Liquidation Company GUC Trust (GUC Trust) assumed responsibility for the affairs of and certain claims against MLC and its debtor subsidiaries that were not concluded prior to MLC's dissolution. MLC transferred to the GUC Trust all of MLC's remaining undistributed shares of our common stock and warrants to acquire our common stock. 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, 2011
Basis Of Presentation
Basis of Accounting [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. These also include the accounts of the 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. Old GM utilized the same principles of consolidation in its consolidated financial statements. 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 assets and liabilities of GM Financial, our automotive finance operations, are presented on a non-classified basis. 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 We changed the presentation of our consolidated balance sheet, consolidated statement of cash flows and certain footnotes 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. In the year ended December 31, 2011 we have recorded foreign currency exchange gains and losses on debt as non-operating items. This is a change from prior period presentations in which foreign currency exchange gains and losses on debt were recorded in Automotive cost of sales. We have reclassified all the successor prior periods to conform to our current presentation. The effects of this reclassification decreased Automotive cost of sales and Interest income and other non-operating income, net by $24 million for the year ended December 31, 2010 and $65 million for the period July 10, 2009 through December 31, 2009. 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 in 2011 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, 2011 and 2010 were $438 million and $337 million. At December 31, 2011 and 2010 other consolidated entities have receivables from our Venezuelan subsidiaries of $380 million and $283 million. The total amounts pending government approval for settlement at December 31, 2011 and 2010 were BsF 2.3 billion (equivalent to $535 million) and BsF 1.9 billion (equivalent to $432 million), for which some requests have been pending from 2007.

Significant Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Significant Accounting Policies

In connection with our application of fresh-start reporting, we established a set of accounting policies which, unless otherwise indicated, utilized the accounting policies of our predecessor entity, Old GM. 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 risks and rewards of ownership have passed, which is generally when a vehicle is released to the carrier responsible for transporting it to a dealer and when collectability is reasonably assured. 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.

Payments received from banks for credit card programs in which there is a redemption liability are recorded on a straight-line basis over the estimated period of time the customer will accumulate and redeem their rebate points. This time period is estimated to be 60 months for the majority of the credit card programs. The redemption liability anticipated to be paid to the dealer is estimated and accrued at the time specific vehicles are sold to the dealer. The redemption cost is classified as a reduction of Automotive sales.

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.

Cash Equivalents

Cash equivalents are defined as short-term, highly-liquid investments with original maturities of 90 days or less.

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.

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. 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.

We measure 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. 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.

An evaluation is made monthly 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 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 purchase 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 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. In connection with fresh-start reporting, we elected to use the FIFO costing method for all inventories previously accounted for by Old GM using the LIFO costing method.

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, including leased vehicles within Total GM Financial Assets, 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 and Old GM had significant investments in vehicles in operating lease portfolios, which are comprised 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 and Old GM was exposed to changes in the residual values of those assets. For impairment purposes, the residual values represent estimates of the values of the assets 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 undiscounted expected future cash flows, which include estimated residual values, are lower than the carrying amount of the asset. 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, and upon disposition a gain or loss is recorded for any difference between the net book value of the lease 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. Impairment charges related to cost method investments are recorded in Interest income and other non-operating, 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. For depreciable property placed in service before January 2001, Old GM used accelerated depreciation methods. For depreciable property placed in service after January 2001, Old GM used the straight-line method. 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 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. In connection with our application of fresh-start reporting, we began amortizing 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. Old GM amortized all special tools using the straight-line method over their estimated useful lives.

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. 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.

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 the fair value for the asset group to be held and used. 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 primarily using the 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 comprise 92% of the non-U.S. pension benefit obligation at December 31, 2011. 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.

In the U.S., Old GM established a discount rate assumption to reflect the yield of a hypothetical portfolio of high quality, fixed-income debt instruments that would produce cash flows sufficient in timing and amount to satisfy projected future benefits.

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.

Group Annuity Contracts

Group annuity contracts are the contracts entered into with a life insurance company, which are used as a funding instrument for specified benefits payments to be made in accordance with the defined benefit pension plans. The contracts may be backed by one or more separately managed investment accounts, which generally hold investments in high quality fixed income securities. The fair value of each contract depends, to a significant extent, on the values of the units of the separately managed investment accounts backing the contract. The fair value of the separately managed investment account assets is based on the fair value of the underlying securities held which are determined by each of the insurance companies. From time to time, the defined benefit pension plans' liabilities may increase when certain contractually required reserves, as estimated by an insurer under the terms of the contract, exceed the fair value of contract assets. The resulting difference represents an outstanding contract asset deficiency that must be funded by the defined benefit pension plan's sponsor. Group annuity contracts are unallocated arrangements and are classified in Level 3.

Common and Preferred Stock

Common and preferred stock securities for which market prices are readily available by the Company 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, floating rate 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 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.

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. Old GM amortized net actuarial gains and losses over the remaining duration of the obligation.

Labor Force

On a worldwide basis, we have and Old GM had a concentration of the workforce working under the guidelines of unionized collective bargaining agreements. At December 31, 2011 48,000 of our U.S. employees (or 62%) were represented by unions, of which 47,000 employees 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 totaling $381 million are being amortized over the four-year contract period.

Job Security Programs

Effective with our current labor agreement the Job Opportunity Bank (JOBS) 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.

Prior to the implementation of the modified job security programs in May 2009, costs for postemployment benefits to hourly employees idled on an other than temporary basis were accrued based on the best estimate of the wage, benefit and other costs to be incurred, and costs related to the temporary idling of employees were expensed as incurred.

Stock Incentive Plans

We measure and record compensation expense for all share-based payment awards based on the award's estimated fair value. We grant awards to our employees through the 2009 Long Term Incentive Plan and the GM Salary Stock Plan. We record compensation expense over the applicable vesting period of an award.

Prior to our public offering in November and December 2010, the fair value of awards granted was based on the estimated fair value of our common stock. Commencing in November 2010 the fair value of our common stock is based on the New York Stock Exchange trading price.

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

Policy, 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 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 and Old GM established 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 and Old GM considered 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 and Old GM utilized 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). Old GM recorded interest income on uncertain tax positions in Interest income and other non-operating income, net, interest expense in Automotive interest expense and penalties in Automotive selling, general and administrative expense.

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. Derivative contracts that are valued based upon models with significant unobservable market inputs, primarily price, are classified in Level 3.

The valuation of derivative liabilities takes into account our nonperformance risk. At December 31, 2011 and 2010 our nonperformance risk was not observable through a liquid credit default swap market. Our nonperformance risk was estimated using internal analysis to develop conclusions on our implied unsecured credit rating, which we used to determine the appropriate credit spread, which would be applied to us by market participants. Prior to receiving published credit ratings we developed our credit rating conclusions using an analysis of comparable industrial companies. At December 31, 2011 and 2010 we incorporated our published credit agency ratings into our credit rating conclusions. Beginning in December 2010 we determined that our non-performance risk no longer represents a significant input in the determination of the fair value of our foreign currency exchange derivatives. Consequently, all automotive operations foreign currency exchange derivative liabilities were reclassified to Level 2.

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 Accumulated other comprehensive income. 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):

Recently Adopted Accounting Principles

In December 2010 the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2010-28, “Intangibles - Goodwill and Other: When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts” (ASU 2010-28). The amendments in ASU 2010-28 modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. ASU 2010-28 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Any resulting goodwill impairment is recorded as a cumulative-effect adjustment to beginning Retained earnings at the date of adoption with future impairments recorded to earnings. Refer to Note 12 for additional information on the adoption of ASU 2010-28 and its effect on the consolidated financial statements.

In September 2011 the FASB issued ASU 2011-08, “Testing Goodwill for Impairment” (ASU 2011-08). Under the revised guidance entities testing for goodwill impairment have an option of performing a qualitative assessment before calculating the fair value for the reporting unit, i.e., Step 1 of the goodwill impairment test. If an entity determines on a basis of qualitative factors that the fair value of the reporting unit is more likely than not less than the carrying amount the first step of the two-step impairment test would be required. If it is not more likely than not that the fair value of the reporting unit is less than the carrying amount, then goodwill is not considered to be impaired. ASU 2011-08 does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test goodwill at least annually for impairment. We adopted ASU 2011-08 effective October 1, 2011. The adoption of this ASU did not have an effect on the conclusions reached during our goodwill impairment assessments performed in the three months ended December 31, 2011.

Accounting Standards Not Yet Adopted

In May 2011 the FASB issued ASU 2011-04, “Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04). Key provisions of the amendments in ASU 2011-04 include: (1) a prohibition on grouping financial instruments for purposes of determining fair value, except in limited cases; (2) an extension of the prohibition against the use of a blockage factor to all fair value measurements; and (3) a requirement that for recurring Level 3 fair value measurements, entities disclose quantitative information about unobservable inputs, a description of the valuation process used and qualitative details about the sensitivity of the measurements. For items not carried at fair value but for which fair value is disclosed, entities will be required to disclose the level within the fair value hierarchy that applies to the fair value measurement disclosed. This ASU is effective for interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 is not expected to have a significant effect on our fair value measurements utilized within the consolidated financial statements.

Acquisition And Disposals Of Businesses

Acquisition and Disposal of Businesses

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):

_________


(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 expenses and other.

(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, 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 and for the periods July 10, 2009 through December 31, 2009 and January 1, 2009 through July 9, 2009, as if the acquisition had occurred on January 1, 2009 (dollars in millions):

Net income (loss) attributable to stockholders	$	440	$	90	$	6,651	$	(4,125	)	$	109,234

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 and January 1, 2009, 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, to Pacific Century Motors. The sale of the Nexteer business included the global steering business which was acquired in October 2009 as discussed under Acquisition of Delphi Businesses below. The 2009 acquisition of Nexteer included 22 manufacturing facilities, six engineering facilities and 14 customer support centers located in North and South America, Europe and Asia.

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 and we remain a significant customer. During the year ended December 31, 2010 Nexteer recorded revenue of $1.8 billion, of which $939 million were sales to us. During the period from October 6, 2009, the date of acquisition, to December 31, 2009, Nexteer reported revenue of $453 million, of which $218 million were sales to us. We did not provide the pro forma financial information because we do not believe the information was material.

Acquisition of General Motors Strasbourg

In October 2010 we acquired 100% of the outstanding equity interest of General Motors Strasbourg S.A.S. (GMS) for cash of one Euro from MLC. GMS is an entity engaged in the business of developing and manufacturing automatic transmissions for luxury and performance light automotive vehicles which was previously owned by Old GM but retained by MLC in connection with the 363 Sale. MLC was unable to sell GMS and upon notification of their plan to liquidate GMS, we agreed to repurchase the business.

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



	Successor
	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.

Sale of India Operations

In December 2009 we and SAIC Motor Hong Kong Investment Limited (SAIC-HK) entered into a joint venture, SAIC GM Investment Limited (HKJV) to invest in automotive projects outside of markets in China, initially focusing on markets in India. In February 2010 we sold certain of our operations in India (GM India), part of our GMIO segment to HKJV, in exchange for a promissory note due in 2013. The amount due under the promissory note may be partially reduced, or increased, based on GM India's cumulative earnings before interest and taxes for the three year period ending December 31, 2012. In connection with the sale we recorded net consideration of $185 million and an insignificant gain. The sale transaction resulted in a loss of control and the deconsolidation of GM India on February 1, 2010. Accordingly, we removed the assets and liabilities of GM India from our consolidated balance sheets and recorded an equity interest in HKJV to reflect cash of $50 million we contributed to HKJV and a $123 million commitment to provide additional capital that we are required to make in accordance with the terms of the joint venture agreement. We recorded a corresponding liability to reflect our obligation to provide additional capital.

In connection with this transaction, we provided an option to SAIC-HK to not participate in future capital injections, which would otherwise be required under certain circumstances. SAIC-HK still held this option at December 31, 2011. The related option liability was $88 million and $24 million at December 31, 2011 and 2010, measured utilizing Level 3 inputs. Total unrealized losses related to this option were $64 million and $3 million in the years ended December 31, 2011 and 2010.

Acquisition of Delphi Businesses

In July 2009 we entered into the Delphi Master Disposition Agreement (DMDA) with Delphi Corporation (Delphi) and other parties. The terms of the DMDA provided a means for Delphi to emerge from bankruptcy and to effectively serve its customers by focusing on its core business. The DMDA settled outstanding claims and assessments against and from MLC, us and Delphi, including the settlement of commitments under the Delphi-GM Settlement Agreements (as defined in Note 20) with limited exceptions, and establishes an ongoing commercial relationship with New Delphi (as subsequently defined). The DMDA also enabled us to access essential components and steering technologies through the businesses we acquired.

We agreed to acquire Nexteer, Delphi's global steering business, which supplied us and other original equipment manufacturers with steering systems and columns, and four domestic facilities that manufacture a variety of automotive components. We and several third party investors agreed to acquire substantially all of Delphi's remaining assets through a newly formed entity, subsequently named Delphi Automotive LLP (New Delphi). We agreed to acquire all the Class A Membership Interests in New Delphi with the other investors acquiring Class B Membership Interests and the Pension Benefit Guarantee Corporation (PBGC) receiving Class C Membership Interests. We also agreed to pay or assume certain Delphi obligations of $1.0 billion.

In October 2009 we consummated the transactions contemplated by the DMDA. We funded the acquisitions, transaction related costs and settlements of certain pre-existing arrangements through net cash payments of $2.7 billion and assumption of liabilities and wind-down obligations of $120 million. We waived our rights to $850 million previously advanced to Delphi and our rights to claims associated with previously transferred pension costs for hourly employees. Of these amounts, we contributed $1.7 billion to New Delphi and paid the PBGC $70 million.

The terms of the DMDA resulted in the settlement of certain obligations related to various commitments accrued as of the transaction date under the Delphi-GM Settlement Agreements. A settlement loss of $127 million was recorded upon consummation of the DMDA. Additional net charges of $49 million were recorded in the three months ended December 31, 2009 associated with the DMDA. Refer to Note 20 for additional information on the Delphi-GM Settlement Agreements.

The following table summarizes the consideration provided under the DMDA and the allocation to its various elements based on their estimated fair values (dollars in millions):



	Successor
	October 6, 2009
Net cash paid	$	2,656
Waived advance agreements, payment terms acceleration agreement and other administrative claims	966
Wind-down obligations and assumed liabilities	120
Total consideration provided	$	3,742

Fair value of Nexteer and four facilities	$	287
Fair value of Class A Membership Interests in New Delphi	1,912
Separately acquired assets of Delphi	41
Settlement of obligation to PBGC	387
Settlement of other obligations to Delphi	1,066
Expenses of the transaction	49
Allocation of fair value to DMDA elements	$	3,742

The following table summarizes the amounts allocated to the fair value of the assets acquired and liabilities assumed of Nexteer and the four domestic facilities, which are included in the results of our GMNA segment (dollars in millions):



	Successor
	October 6, 2009
Total current assets, primarily accounts and notes receivable, net of $541	$	854
Total non-current assets, primarily property, net of $202(a)	305
Total current liabilities, primarily accounts payable of $316	(484		)
Total non-current liabilities, primarily other liabilities and deferred income taxes	(374		)
Noncontrolling interests	(14		)
Fair value of Nexteer and four domestic facilities	$	287

__________

(a)

Includes goodwill of $61 million recorded in the GMNA reporting unit that arises from the difference between the economic value of long-term employee related liabilities and their recorded amounts at the time of acquisition and deferred taxes. The total amount of goodwill deductible for tax purposes is expected to be $398 million. The difference between book goodwill and tax goodwill results from different allocations for tax purposes than that utilized for book purposes.

Since we and Old GM historically accounted for a significant portion of Nexteer's and the four domestic facilities' sales and because we were providing subsidies to Delphi related to these facilities, the acquisition of these businesses did not have a significant effect on our consolidated financial results as the costs associated with these facilities have been recorded as inventory costs and recorded in Automotive cost of sales. We did not provide pro forma financial information because we do not believe this information would be material given the intercompany nature of Nexteer and the four domestic facilities sales activity. Refer to Note 20 for additional information on the Nexteer acquisition.

In March 2011 we sold our Class A Membership Interest in New Delphi for $3.8 billion. Refer to Note 10 for additional information.

Saab Bankruptcy and Sale

In February 2009 Saab Automobile AB (Saab), part of our GME segment, filed for protection under the reorganization laws of Sweden. Old GM determined that the reorganization proceeding resulted in a loss of the elements of control necessary for consolidation and therefore Old GM deconsolidated Saab in February 2009. Old GM recorded a loss of $824 million in Other automotive expenses, net related to the deconsolidation. The loss reflected the remeasurement of Old GM's net investment in Saab to its estimated fair value of $0, costs associated with commitments and obligations to suppliers and others, and a commitment to provide up to $150 million of debtor-in-possession (DIP) financing. We acquired Old GM's investment in Saab in connection with the 363 Sale. In August 2009 Saab exited its reorganization proceeding, and we regained the elements of control and consolidated Saab at an insignificant fair value.

In February 2010 we completed the sale of Saab and in May 2010 we completed the sale of Saab Automobile GB 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 DIP 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.

The following table summarizes the estimated fair value, carrying amount and various methods and assumptions used in valuing GM Financial's finance receivables (dollars in millions):



	Successor
	December 31, 2011				December 31, 2010
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
Finance receivables, net(a)	$	9,162	$	9,386	$	8,197	$	8,186

__________


(a)	The fair value is estimated based upon forecasted cash flows discounted using a pre-tax weighted-average cost of capital (WACC). The forecast includes factors such as prepayment, defaults, recoveries and fee income assumptions.

Finance contracts are purchased by GM Financial 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, 2011 and 2010 the accrual of finance charge income has been suspended on delinquent finance receivables based on contractual amounts due of $439 million and $491 million.

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. At December 31, 2011 as a result of improvements in the credit performance of the pre-acquisition portfolio, which resulted in an increase of expected cash flows of $261 million, GM Financial transferred the excess non-accretable discount to accretable yield. GM Financial will recognize this excess as finance charge income over the remaining life of the portfolio.

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



	Successor
	Year Ended December 31, 2011			October 1, 2010 Through December 31, 2010
Balance at beginning of period	$	1,201		$	1,436
Accretion of accretable yield	(725		)	(235		)
Transfer from non-accretable discount	261			—
Balance at end of period	$	737		$	1,201

The following table summarizes activity for the allowance for post-acquisition loan losses (dollars in millions):



	Successor
	Year Ended December 31, 2011			October 1, 2010 Through December 31, 2010

Charge-offs	(66		)	—
Recoveries	41			—
Balance at end of period	$	179		$	26

Credit Quality

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):



	Successor
	December 31, 2011		December 31, 2010
FICO score less than 540	$	2,133	$	1,328
FICO score 540 to 599	4,167		3,396
FICO score 600 to 659	2,624		2,758
FICO score greater than 660	756		1,166
Balance at end of period(a)	$	9,680	$	8,648

__________


(a)	Balance at end of period is the sum of pre-acquisition finance receivables - outstanding balance and post-acquisition finance receivables, net of fees.

Delinquency

The following summarizes the contractual amount of 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):



	Successor
	December 31, 2011				December 31, 2010
	Amount		Percent of Contractual Amount Due		Amount		Percent of Contractual Amount Due
Delinquent contracts
31-to-60 days	$	517	5.3	%	$	535	6.2	%
Greater-than-60 days	182		1.9	%	212		2.4	%
Total finance receivables more than 30 days delinquent	699		7.2	%	747		8.6	%
In repossession	27		0.3	%	28		0.3	%
Total finance receivables more than 30 days delinquent and in repossession	$	726	7.5	%	$	775	8.9	%

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.

Equity In Net Assets Of Nonconsolidated Affiliates

Equity in Net Assets of Nonconsolidated Affiliates

Automotive

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 tables summarizes information regarding equity in income (loss), net of tax and gain on disposal of investments and disposition of interest in nonconsolidated affiliates (dollars in millions):

We received dividends from nonconsolidated affiliates of $1.2 billion, $685 million and $134 million in the years ended December 31, 2011 and 2010 and the period July 10, 2009 through December 31, 2009, and Old GM received dividends of $220 million in the period January 1, 2009 through July 9, 2009. At December 31, 2011 we had undistributed earnings including dividends declared but not received, of $1.6 billion related to our nonconsolidated affiliates.

Investment in China JVs

The following table summarizes our direct ownership interests in our Chinese joint ventures, collectively referred to as China JVs:

Shanghai Chengxin Used Car Operation and Management Co., Ltd. (Shanghai Chengxin Used Car)	33	%	33	%
SAIC General Motors Sales Co., Ltd. (SGMS)	49	%

Sales and income of our China JVs are not consolidated into our financial statements; rather, our proportionate share of the earnings of each joint venture is reflected as Equity income, net of tax and gain on disposal of investments.

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

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

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 is contingently exercisable based on events which we do not unilaterally control. As part of the loan arrangement SAIC provided a commitment whereby, in the event of default, SAIC will purchase the ownership interest in SGM that we pledged as collateral for the loan. We recorded an insignificant gain on this transaction.

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

Impairment of Investment in HKJV

In March 2011 there was a change in the local tax regulations which significantly extended the period of time over which GM India will receive certain value added tax based investment incentives. The delay in recovery of these incentives significantly affected GM India's cash flow and earnings before interest and income taxes forecasts, resulting in a decrease in the fair value of HKJV. The fair value of our investment in HKJV at March 31, 2011 was determined to be $112 million compared to a carrying amount of $151 million. The loss in value was determined to be other than temporary and, 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 in the three months ended March 31, 2011. Refer to Note 4 for additional information related to HKJV.

VMM Deconsolidation

In June 2011 we entered into a new shareholder agreement with Fiat Powertrain Technologies SPA related to VM Motori (VMM) in Italy. 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.

Ally Financial Common and Preferred Stock

On July 10, 2009 we acquired the investment in Ally Financial's common and preferred stocks in connection with the 363 Sale.

In December 2009 the United States Department of the Treasury (UST) made a capital contribution to Ally Financial of $3.8 billion. The UST also exchanged all of its existing Ally Financial non-convertible preferred stock for mandatory convertible preferred securities valued at $5.3 billion and converted mandatory convertible preferred securities valued at $3.0 billion into Ally Financial common stock. These actions resulted in the dilution of our investment in Ally Financial common stock from 24.5% to 16.6%, of which 6.7% was held directly and 9.9% was held indirectly through an independent trust.

In December 2010 the UST agreed to convert 110 million shares of preferred securities into 532 thousand 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, 2011 and 2010 our equity ownership in Ally Financial was 9.9%.

Fair Value and Impairment of Ally Financial Common and Preferred 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, 2011 and 2010 financial statements, financial statements and price to tangible book value multiples of comparable companies in the banking and finance industry, and the effects of certain Ally Financial Shareholder rights described below. The measurement of Ally Financial common stock is a Level 3 fair value measurement.

At December 31, 2011 we determined the carrying amount of our investment in Ally Financial common stock exceeded our estimate of its fair value. Our current estimate of fair value results 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 have concluded the impairment is other than temporary. As a result we have recorded an impairment charge of $555 million in Interest income and other non-operating income, net to reduce our investment to its current estimated fair value of $403 million.

In March 2011 our investment in Ally Financial preferred stock was sold through a public offering for net proceeds of $1.0 billion. The gain of $0.3 billion related to the sale was recorded in Interest income and other non-operating income, net.

We calculated the fair value of our investment in Ally Financial preferred stock as of December 31, 2010 using a discounted cash flow approach. The present value of the cash flows was determined using assumptions regarding the expected receipt of dividends on Ally Financial preferred stock and the expected call date.

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



	Successor
	December 31, 2011		December 31, 2010
Common stock
Carrying amount	$	403	$	964
Fair value	$	403	$	1,031
Preferred stock
Carrying amount			$	665
Fair value			$	1,055

At December 31, 2009 we determined that indicators were present that suggested our investments in Ally Financial common and preferred stock could be impaired. Such indicators included the continuing deterioration in Ally Financial's mortgage operations, as evidenced by the strategic actions Ally Financial took in December 2009 to position itself to sell certain mortgage assets. These actions resulted in Ally Financial recording an increase in its provision for loan losses of $2.4 billion in the three months ended December 31, 2009. These indicators also included Ally Financial's receipt of $3.8 billion of additional financial support from the UST on December 30, 2009. As a result of these impairment indicators, we evaluated the fair value of our investments in Ally Financial common and preferred stock and recorded an impairment charge of $270 million related to our Ally Financial common stock to record the investment at its estimated fair value of $970 million.

Old GM

In January 2009 Old GM received a loan from the UST to purchase 190,921 Class B Common Membership Interests in Ally Financial. The UST had the option to convert outstanding amounts under the loan into a maximum of 190,921 shares of Ally Financial's Class B Common Membership Interests on a pro rata basis. In May 2009 the UST exercised this option, the outstanding principal and interest under the loan was extinguished, and Old GM recorded a net gain of $483 million. The net gain was comprised of a gain on the disposition of Ally Financial Common Membership Interests of $2.5 billion recorded in Equity in income of and disposition of interest in Ally Financial and a loss on extinguishment of the loan of $2.0 billion recorded in Loss on extinguishment of debt. After the exchange, Old GM's ownership was reduced to 24.5% of Ally Financial's Common Membership Interests.

Ally Financial converted its status to a C corporation effective June 30, 2009. At that date, Old GM began to account for its investment in Ally Financial using the cost method rather than the equity method as Old GM could not exercise significant influence over Ally Financial. Prior to converting to a C corporation, Old GM's investment in Ally Financial was accounted for in a manner similar to an investment in a limited liability partnership and the equity method was applied because Old GM's influence was more than minor. In connection with Ally Financial's conversion into a C corporation, each unit of each class of Ally Financial Membership Interests was converted into shares of capital stock of Ally Financial with substantially the same rights and preferences as such Membership Interests.

The following table summarizes financial information of Ally Financial for the period Ally Financial was accounted for as a nonconsolidated affiliate (dollars in millions):

(a)

The fair value of related assets was determined to be $0 in the years ended December 31, 2011 and 2010 and the period from July 10, 2009 through December 31, 2009 and $0 to $85 million in the period from January 1, 2009 through July 9, 2009 measured utilizing level 3 inputs. Fair value measurements of long-lived assets utilized projected cash flows discounted at a rate commensurate with the perceived business risks related to the assets involved.


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

Old GM initiated restructuring plans prior to the 363 Sale to reduce the total number of powertrain, stamping and assembly plants and to eliminate certain brands and nameplates. In addition, MLC retained certain assets that we did not acquire in connection with the 363 Sale and were deemed not to have a useful life beyond July 9, 2009. Old GM recorded incremental depreciation and amortization on certain of these assets as they were expected to be utilized over a shorter period of time than their previously estimated useful lives. We record incremental depreciation and amortization for changes in useful lives subsequent to the initial determination. Old GM recorded incremental depreciation and amortization of approximately $2.8 billion in the period January 1, 2009 through July 9, 2009.

(a)	Refer to Note 4 for additional information concerning the acquisition of AmeriCredit.


(b)	Refer to Note 10 for additional information concerning the deconsolidation of VMM.


(c)	Includes impairment charges of $1.5 billion recorded as a cumulative-effect adjustment to beginning Retained earnings due to the adoption of ASU 2010-28.

We adopted the provisions of 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 December 31, 2011 and at March 31, 2011 we recorded impairment charges of $1.0 billion in the year ended December 31, 2011. Refer to Note 3 for additional information on ASU 2010-28.

In the three months ended December 31, 2011, 2010 and 2009 we performed our annual goodwill impairment testing as of October 1 for all reporting units. Based on this testing we determined that goodwill was impaired for our GM Korea reporting unit at October 1, 2011. 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 and determined that there was an event-driven impairment in our GM Korea reporting unit. As such we recorded Goodwill impairment charges of $270 million in the three months ended December 31, 2011 within our GMIO segment. These goodwill impairment charges primarily represent the decrease in the fair value-to-U.S. GAAP differences (which originated upon our application of fresh-start reporting in 2009) resulting from the reversal of valuation allowances in Holden.

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 year ended December 31, 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 a decrease in our nonperformance risk and an improvement in our incremental borrowing rates since July 10, 2009. At certain of the testing dates the net decrease also resulted from an increase in the high quality corporate bond rates utilized to measure our employee benefit obligations and a decrease in credit spreads between high quality corporate bond rates and market interest rates for companies with similar nonperformance risk. In addition, for the purpose of deriving an implied goodwill balance, deterioration in the business outlook for certain reporting units resulted in a reduction in the amount of deferred taxes giving rise to goodwill through the application of Accounting Standards Codification (ASC) 805, “Business Combinations” (ASC 805) and an increase in estimated employee benefit obligations.

In the year ended December 31, 2011 our market capitalization (including the fair value of our preferred stock and warrants) declined and at times it approximated our recorded Total equity. The fair values of our reporting units determined in our annual goodwill impairment test decreased from the prior year, with the fair values of our GME and GM Korea reporting units decreasing below their carrying amounts. The decrease in GME was driven primarily by a higher level of anticipated economic weakness in Europe in the near- and medium-term. The decrease in GM Korea 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.

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 ASC 805.

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):



							Industry Sales(c)		Market Share(c)
	Goodwill(b)		WACC		Long-Term Growth Rates		2011/2012	2015/2016	2011/2012		2015/2016

GME - At October 1, 2011	$	1,246	17.5	%	0.5	%	19.4	21.7	6.7	%	7.0	%
GME - At December 31, 2011	$	1,193	18.5	%	0.5	%	19.4	22.3	6.3	%	6.9	%
GM Korea - At October 1, 2011(a)	$	615	15.5	%	3.0	%	81.0	97.1	1.4	%	1.1	%
GM Korea - At December 31, 2011(a)	$	596	15.5	%	3.0	%	81.0	97.1	1.4	%	1.1	%
Holden - At December 31, 2011	$	197	14.0	%	2.0	%	1.2	1.3	12.5	%	12.6	%

_________


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


(b)	Goodwill balance is before any adjustments, if any, for goodwill impairments.


(c)	GME amounts at January 1, 2011 and March 31, 2011 are 2011 through 2015 and GME amounts at December 31, 2011 are 2012 through 2016. All others amounts are 2012 through 2015.

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 certain of our testing dates our Step 2 analyses indicated GME's, GM Korea's and Holden's implied goodwill was less than their recorded goodwill; therefore, goodwill was adjusted at various dates in the year ended December 31, 2011.

Future goodwill impairments that may be material could be recognized should the recent 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 (which could occur in the near future if additional positive evidence becomes available).

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

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, 2011 and 2010 (1) Total assets recognized for these consolidated VIEs were $463 million and $481 million, which were comprised of Cash and cash equivalents, Accounts and notes receivables, net, Inventories, and Property, net; and (2) Total liabilities were $298 million and $307 million, which were comprised of Accounts payable (principally trade), and Accrued and other liabilities. 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. In the years ended December 31, 2011 and 2010 Total net sales and revenue recorded for these consolidated VIEs were $748 million and $753 million and Net income was $61 million and $84 million, the most significant of which were attributable to GM Egypt. Prior to 2010, Total assets and liabilities recognized were not significant.

GM Korea, a non-wholly owned consolidated subsidiary that we control through a majority voting interest, is also a VIE because in the future it may require additional subordinated financial support. The creditors of GM Korea's short-term debt of $171 million and $70 million, current derivative liabilities of $44 million and $111 million and long-term debt of $7 million and $835 million at December 31, 2011 and 2010 do not have recourse to our general credit. In February 2011 we provided a guarantee to a minority shareholder in GM Korea to repurchase GM Korea's preferred shares according to the redemption schedule should GM Korea not repurchase the shares. This guarantee decreased the amount of long-term debt which did not have recourse to our general credit in the year ended December 31, 2011.

Automotive Financing - GM Financial

GM Financial finances its loan and lease origination volume through the use of credit facilities and securitization trusts that issue asset-backed securities to investors. GM Financial retains a residual interest in these entities and is not required to provide any additional financial support to its sponsored credit facilities and securitization SPEs. The SPEs are considered VIEs because they do not have sufficient equity at risk and are consolidated because GM Financial has the power over those activities that most significantly affect the economic performance of the SPEs. Refer to Notes 5, 6 and 17 for additional information on GM Financial's involvement with 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.

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 provide financial support, including American Axle and Manufacturing Holdings, Inc. (American Axle), Ally Financial and HKJV. We concluded these entities are VIEs because they do not have sufficient equity at risk or will 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 28 (dollars in millions):

Capital leases	992		661
Total automotive debt	$	5,295	$	4,630

__________


(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 Health Care Trust (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.

Korea Preferred Shares

GM Korea has non-convertible mandatorily redeemable preferred shares outstanding of $978 million and $835 million at December 31, 2011 and December 31, 2010. Dividends accrue at a rate of 2.5% through October 2012 at which time the rate increases to 7.0% and remains in effect through 2017. The preferred shares are redeemable in periodic installments through 2017. In February 2011 we provided a guarantee to repurchase the preferred shares according to the redemption schedule if GM Korea does not have sufficient legally distributable earnings to redeem the shares. GM Korea has the option to redeem the shares early provided sufficient legally distributable earnings exist.

Secured Revolving Credit Facility

In October 2010 we entered into a five year, $5.0 billion secured revolving credit facility which includes a letter of credit sub-facility of up to $500 million. Additionally, we can use collateral under the revolving credit facility to support up to $2.0 billion of other obligations. While we do not believe that we will draw on the secured revolving credit facility to fund operating activities, the facility is expected to provide additional liquidity and financing flexibility. Availability under the secured revolving credit facility is subject to borrowing base restrictions.

Our obligations under the secured revolving credit facility are guaranteed by certain of our domestic subsidiaries and by substantially all of our domestic assets, including accounts receivable, inventory, property, plants, and equipment, real estate, intercompany loans, intellectual property and trademarks. Obligations are also secured by the 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 facility does not include, among other assets, cash, cash equivalents, marketable securities, as well as our investment in GM Financial and our equity interests in our China JVs and in GM Korea. If we receive an investment grade corporate rating from two or more of the credit rating agencies: Fitch Ratings, Moody's Investor Service and Standard & Poor's, we may no longer have to post collateral under the terms of the facility.

Interest rates on obligations under the secured revolving credit facility 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 debt evidenced by the secured revolving credit facility.

UST Credit Agreement

On July 10, 2009 we entered into a loan agreement with the UST, as amended (UST Credit Agreement) and assumed debt of $7.1 billion maturing on July 10, 2015 which Old GM incurred under its secured superpriority debtor-in-possession credit agreement with the UST and EDC (DIP Facility). In April 2010 we repaid the full outstanding amount of $4.7 billion using funds from our escrow account. 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 and the executive compensation and corporate governance provisions of Section 111 of the Emergency Economic Stabilization Act of 2008, as amended, including the Interim Final Rule implementing Section 111 (the Interim Final Rule), remain in effect until the earlier to occur of the UST ceasing to own direct or indirect equity interests in us or our ceasing to be a recipient of exceptional financial assistance, as determined pursuant to the Interim Final Rule, and impose obligations on us with respect to, among other things, certain expense policies, executive privileges and compensation requirements.

VEBA Notes

In 2009 in connection with the 363 Sale, we entered into the VEBA Note Agreement and issued notes (VEBA Notes) of $2.5 billion to the UAW Retiree Medical Benefits Trust (New VEBA). The VEBA Notes had an implied interest rate of 9.0% per annum. In October 2010 we repaid in full the outstanding amount (together with accreted interest thereon) of the VEBA Notes of $2.8 billion, which resulted in a gain of $198 million included in Gain (loss) on extinguishment of debt.

Canadian Loan Agreement and EDC Loan Facility

On July 10, 2009 we entered into the amended and restated loan agreement with the EDC and assumed a $1.3 billion term loan (Canadian Loan) from the EDC under a loan and security agreement entered into in April 2009 (EDC Loan Facility) maturing on July 10, 2015. In March 2010 and December 2009 we made quarterly payments of $194 million and $192 million on the Canadian Loan. In April 2010 we repaid in full the outstanding amount of the Canadian Loan of $1.1 billion. Amounts repaid under the agreement may not be reborrowed.

Technical Defaults and Covenant Violations

Several of our loan facilities, including our secured revolving credit facility 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, 2011.

Total GM Financial debt	$	8,538	$	8,556	$	7,032	$	7,011

__________

(a)

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


(b)	Senior notes and convertible senior notes are included in GM Financial Other liabilities.

Senior Notes and Convertible Senior Notes

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.

As a result of the acquisition of AmeriCredit, the holders of previous senior notes and convertible senior notes had the right to require GM Financial to repurchase some or all of their notes as provided in the indentures for such notes. During the three months ended December 31, 2010 GM Financial repurchased convertible senior notes and senior notes of $463 million.

Credit Facilities

The following table summarizes further details regarding terms and availability of GM Financial's credit facilities at December 31, 2011 (dollars in millions):

__________


(a)	These amounts do not include cash collected on finance receivables pledged of $35 million which is included in GM Financial Restricted cash at December 31, 2011.


(b)	In February 2011 GM Financial extended the maturity date of the syndicated warehouse facility to May 2012 and increased the borrowing capacity to $2.0 billion from $1.3 billion.


(c)	In January 2012 GM Financial extended the maturity date of the lease warehouse facility for lease originations in the U.S. to January 2013. Borrowings on the facility are collateralized by leased assets.


(d)	In July 2011 GM Financial Canada Leasing Ltd., a subsidiary of GM Financial entered into a lease warehouse facility for lease originations in Canada that matures in July 2012. Borrowings on the facility are collateralized by leased assets. The facility amount represents CAD $600 million at December 31, 2011.


(e)	The revolving period under this facility has ended and the outstanding debt balance will be repaid over time based on the amortization of the receivables pledged until October 2016 when any remaining amount outstanding will be due and payable.

Credit Facility Covenants

GM Financial is required to hold certain funds in restricted cash accounts to provide additional collateral for borrowings under certain of its credit facilities. The credit facilities contain various covenants requiring minimum financial ratios, asset quality and portfolio performance ratios including 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 or restrict GM Financial's ability to obtain additional borrowings under this facility. At December 31, 2011 GM Financial was in compliance with all covenants in its credit facilities. Refer to Note 14 for additional discussion on GM Financial's restricted cash.

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, 2011 and 2010 unamortized purchase accounting premium of $43 million and $107 million is included in Securitization notes payable.

__________


(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.

Securitization Notes Payable Covenants

With respect to GM Financial's securitization transactions covered by a financial guaranty insurance policy, agreements with the insurers provide that if portfolio performance ratios (delinquency, cumulative default or cumulative net loss) in a trust's pool of receivables exceed certain targets, the specified credit enhancement levels would be increased.

Agreements with GM Financial's financial guaranty insurance providers contain additional specified targeted portfolio performance ratios that are higher than those described in the preceding paragraph. If, at any measurement date, the targeted portfolio performance ratios with respect to any insured trust were to exceed these higher levels, provisions of the agreements permit GM Financial's financial guaranty insurance providers to declare the occurrence of an event of default and terminate GM Financial's servicing rights to the receivables transferred to that trust. At December 31, 2011 no such servicing right termination events have occurred with respect to any of the trusts formed by GM Financial.

Old GM

Secured Revolving Credit Facility, U.S. Term Loan and Secured Credit Facility

In March 2009 Old GM entered into an agreement to amend its $1.5 billion U.S. term loan. Because the terms of the amended U.S. term loan were substantially different than the original terms, due primarily to the revised borrowing rate, Old GM accounted for the amendment as a debt extinguishment. As a result, Old GM recorded the amended U.S. term loan at fair value and recorded a gain on the extinguishment of the original loan facility of $906 million in the period January 1, 2009 through July 9, 2009.

In connection with the relief sought under U.S. bankruptcy laws (Chapter 11 Proceedings), Old GM's $4.5 billion secured revolving credit facility, $1.5 billion U.S. term loan and $125 million secured credit facility were paid in full on June 30, 2009. Old GM recorded a loss of $958 million in Reorganization gains, net related to the extinguishments of the debt due primarily to the face value of the U.S. term loan exceeding the carrying amount.

Contractual interest expense not accrued or recorded on pre-petition debt was $200 million in the period January 1, 2009 through July 9, 2009 (includes contractual interest expense related to contingent convertible debt of $44 million).

Contingent Convertible Debt

Old GM adopted the provisions of ASC 470-20, “Debt with Conversion and Other Options” (ASC 470-20) in January 2009, with retrospective application to prior periods. At July 9, 2009 Old GM's contingent convertible debt outstanding was $7.4 billion, comprised of principal of $7.9 billion and unamortized discounts of $551 million. Upon adoption of ASC 470-20, the effective interest rate on Old GM's outstanding contingent convertible debt ranged from 7.0% to 7.9%. In connection with the 363 Sale, MLC retained the contingent convertible debt.

The following table summarizes the components of interest expense related to contingent convertible debt (dollars in millions):



	Predecessor

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. Non-skilled trade hourly U.S. employees hired after October 15, 2007 participate in a defined benefit cash balance plan which was frozen on January 2, 2012 and will be terminated in 2012 subject to regulatory approvals. In September 2010 the U.S. hourly defined benefit pension plan was amended to create a legally separate new defined benefit pension plan for entry level participants who are covered by the cash balance benefit formula. The underlying benefits offered to plan participants were unchanged. 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. There is also an unfunded nonqualified pension plan covering certain U.S. executives for service prior to January 1, 2007, and it is based on an “excess plan” for service after that date.

In January 2012 we amended the U.S. salaried pension plan to cease the accrual of additional benefits effective September 30, 2012. Active plan participants will receive additional contributions in the defined contribution plan starting in October 2012. This amendment will result in a curtailment, with an insignificant expense effect, and reduce the projected benefit obligation by approximately $300 million.

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, 2011 all legal funding requirements had been met. We expect to contribute $100 million to our U.S. non-qualified plans and $740 million to our non-U.S. pension plans in 2012.

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



	Successor						Predecessor
	Year Ended December 31, 2011		Year Ended December 31, 2010		July 10, 2009 Through December 31, 2009		January 1, 2009 Through July 9, 2009
U.S. hourly and salaried	$	1,962	$	4,095	$	31	$	57
Non-U.S.	836		777		4,287		529
Total	$	2,798	$	4,872	$	4,318	$	586

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

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):

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 participate in a defined contribution plan. Contributions are also made to certain non-U.S. defined contribution plans.

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

Significant Plan Amendments, Benefit Modifications and Related Events

Remeasurements

The change in benefit obligation for the years ended December 31, 2011 and 2010 include interim remeasurements. For the year ended December 31, 2010 there were no significant remeasurements, curtailments or settlements as a result of changes to the underlying benefits offered to the plan participants.

In the three months ended September 30, 2011 a plan which provides legal services to U.S. hourly employees and retirees was remeasured as a result of our current labor agreement provisions which terminate the plan effective December 31, 2013. The 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 income, which will be amortized through December 31, 2013.

Canadian Health Care Trust

In October 2011 pursuant to a June 2009 agreement between 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 as a component of 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 $414 million of accumulated other comprehensive losses.

U.S. pension plan service cost include administrative expenses of $138 million, $97 million, and $38 million for the years ended December 31, 2011 and 2010, and the period July 10, 2009 through December 31, 2009. Weighted-average assumptions used to determine net expense are determined at the beginning of the period and updated for remeasurements.

Assumptions

Healthcare Trend Rate

As a result of modifications made to healthcare plans in connection with the 363 Sale, 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	Non-U.S. Plans
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 (dollars in millions):

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 return on asset assumptions for 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 fund performance and historical returns, the expected 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 optimal 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 December 2011 an analysis of the investment policy was completed for the U.S. pension plans considering: (1) our overall balance sheet derisking strategy; (2) the plans are closed to new participants; and (3) the 2011 UAW negotiations did not increase pension benefits. Separate long-term strategies were developed for the salaried and hourly U.S. pension plans which represent 35% and 65% of total U.S. pension plans' assets. Using an approach which matches plan assets and liability cash flows to minimize risk of funded status volatility, the expected weighted-average return on assets was reduced from 8.0% at December 31, 2010 to 5.7% for the salaried pension plan and to 6.5% for the hourly pension plan. The resulting weighted-average return is 6.2% The overall decrease is primarily due to a different asset mix consisting of a higher proportion of fixed income investments compared to last year. The salaried pension plan has a higher target proportion of fixed income investments than the hourly pension plan and therefore, a lower expected return on assets than the hourly pension plan.

The expected 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 6.5% and 7.4% for the years ended December 31, 2011 and 2010 represent weighted-average rates of all of the funded non-U.S. plans.

Investment in Trusts

The assets of the U.S. hourly and salaried pension plans are held by various master trusts and group trusts (collectively “Trusts”). The master trusts hold only GM sponsored pension plan assets. The group trusts permit the commingling of the assets of more than one employee benefit plan, including plans of unrelated sponsors. The plans that participate in the Trusts own an undivided beneficial interest in the underlying assets and changes therein of the respective Trusts. During 2011 certain assets held by several group trusts for the benefit of unrelated plan sponsors were liquidated which resulted in the beneficial interest in the remaining assets within these group trusts becoming solely owned by the GM sponsored pension plans. The residual beneficial interest of unrelated benefit plan sponsors in the other group trusts is not significant. The following fair value measurement tables reflect the underlying assets held by the Trusts for the benefit of our U.S. pension plans on a combined basis and exclude the remaining beneficial interest in the assets within the group trusts owned by unrelated benefit plan sponsors.

Transfers In and/or Out of Level 3

There were no significant transfers of U.S. plan assets into and/or out of Level 3 during the year ended December 31, 2011.

Significant transfers of U.S. plan assets out of Level 3 into Level 2 for the year ended December 31, 2010 included $1.3 billion, of government and agency debt securities, $0.7 billion of corporate debt securities, $0.7 billion of non-agency mortgage and asset-backed securities and $4.7 billion of investment funds. Except for investment funds, these transfers were the result of improved pricing transparency of these securities which allowed management to corroborate observable pricing inputs received from independent pricing services. Investment fund transfers were the result of management's ability to validate certain liquidity and redemption restrictions that permit the plans to redeem their interests at NAV in the near-term (generally within 90 days).

There were no significant transfers of non-U.S. plan assets into and /or out of Level 3 during the years ended December 31, 2011 and 2010.

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.

Certain plan assets represent investments in group annuity contracts. We entered into group annuity contracts with various life insurance companies to provide pension benefits to certain of our salaried workforce and backed these obligations by high quality fixed income securities. We, as the plans' sponsor, might be exposed to counterparty risk if any or all of the life insurance companies fail to perform in accordance with the terms and conditions stipulated in the contracts, or any or all of the life insurance companies become insolvent or experience other forms of financial distress. We and the plans might also be exposed to liquidity risk due to the funding obligation that may arise under these contracts. The plans' management monitors counterparty and liquidity risks on an on-going basis and has procedures in place that are designed to monitor the financial performance of the life insurance companies that are parties to these contracts and maintain flexibility in addressing contract-specific and broader market 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 are 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 our derivatives at December 31, 2011 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 (PPA), which govern the manner in which we fund and administer our pensions for our retired employees and their spouses. The Pension Relief Act of 2010 provides us with options to amortize any shortfall amortization base for U.S. qualified pension plans either (1) over seven years with amortization starting two years after the election of this relief or (2) over 15 years.

We also maintain pension plans for employees in a number of countries outside the U.S. which are subject to local laws and regulations. We have elected the 15-year amortization funding relief option for certain of our U.S. pension plans for the most recent pension funding valuation as of October 1, 2010. The election of the 15-year amortization option has enabled us to defer the funding requirements to future years. No election is required at this time for the plan year beginning October 1, 2011, and we plan to evaluate these options in the future for our U.S. qualified pension plans. We have no funding requirements for our U.S. qualified plans in 2012.

Derivative Financial Instruments And Risk Management

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 in connection with the management of exposure to fluctuations in certain foreign currency exchange rates and commodity prices. At December 31, 2011 our derivative instruments consisted primarily of forward contracts and options.

At December 31, 2011 and 2010 no outstanding derivative contracts were designated in hedging relationships.

Counterparty Credit Risk

Derivative financial instruments contain an element of credit risk attributable to the counterparties' ability to meet the terms of the agreements. Certain of our agreements with counterparties require, under certain circumstances, that the counterparty post collateral with us for net asset positions. Agreements are entered into with counterparties that allow the set-off of certain exposures in order to manage the risk. Collateral held from counterparties was insignificant and $74 million at December 31, 2011 and December 31, 2010.

At December 31, 2011 substantially all derivative counterparty exposures were with counterparties that were rated A- or higher.

Credit Risk Related Contingent Features

Certain of our agreements with counterparties require that we provide cash collateral for net liability positions that we may have with such counterparty. At December 31, 2011 no collateral was posted related to derivative instruments, and we did not have any agreements with counterparties to derivative instruments containing covenants requiring the maintenance of certain credit rating levels or credit risk ratios that would require the posting of collateral in the event that such covenants are violated.

Fair Value of Derivatives

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

At December 31, 2011 and 2010, our non-performance risk was not observable through a liquid credit default swap market. In the three months ended December 31, 2010 we determined that our non-performance risk no longer represented a significant input in the determination of the fair value of our foreign currency exchange derivatives. The effect of our non-performance risk in the valuation was reduced due to the reduction in the remaining duration and magnitude of these net derivative liability positions. In October 2010 we transferred foreign currency derivatives with a fair market value of $183 million out of Level 3 to Level 2.

Other Derivatives

In September 2009 in connection with an agreement with American Axle, we received warrants to purchase 4 million shares of American Axle common stock exercisable at $2.76 per share. At December 31, 2010 the fair value of these warrants was $44 million. In February 2011 we exercised the warrants and sold the shares and received proceeds of $48 million.

In 2010 we entered into 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. The fair value of this embedded derivative was an asset of $148 million at December 31, 2011 and insignificant at December 31, 2010.

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 and the period July 10, 2009 through December 31, 2009 we recorded cash flow hedge losses of $22 million and $1 million related to our share of New Delphi's hedging 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 income were reclassified to earnings and recorded in the gain on sale of New Delphi. Refer to Note 4 for additional information on the sale of New Delphi.

Derivatives Not Meeting a Scope Exception from Fair Value Accounting

We entered into purchase contracts that were accounted for as derivatives with changes in fair value recorded in Interest income and other non-operating income, net, as these contracts do not qualify for the normal purchases and normal sales scope exception in ASC 815, "Derivatives and Hedging" (ASC 815).

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.

The effect of derivative instruments on earnings and Accumulated other comprehensive income was insignificant for the years ended December 31, 2011 and 2010.

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, 2011 and 2010 these restricted cash accounts totaled $36 million and $33 million and were recorded in GM Financial Restricted cash.

Old GM

Derivatives and Hedge Accounting

Derivatives Not Designated for Hedge Accounting

Old GM previously entered into a variety of foreign currency exchange, interest rate and commodity forward contracts and options to maintain a desired level of exposure arising from market risks resulting from changes in foreign currency exchange rates, interest rates and certain commodity prices.

In May 2009 Old GM reached agreements with certain of the counterparties to its derivative contracts to terminate the derivative contracts prior to stated maturity. Commodity, foreign currency exchange and interest rate forward contracts were settled for cash of $631 million, resulting in a loss of $537 million. The loss was recorded in Automotive sales and revenue, Automotive cost of sales and Automotive interest expense in the amounts of $22 million, $457 million and $58 million.

When an exposure economically hedged with a derivative contract was no longer forecasted to occur, in some cases a new derivative instrument was entered into to offset the exposure related to the existing derivative instrument. In some cases, counterparties were unwilling to enter into offsetting derivative instruments and, as such, there was exposure to future changes in the fair value of these derivatives with no underlying exposure to offset this risk. In the period January 1, 2009 through July 9, 2009, Old GM recorded gains of $91 million related to derivatives originally entered into to hedge exposures that subsequently became probable not to occur. These gains were recorded to Interest income and other non-operating income, net.

Gains (Losses) on Derivatives

The following table summarizes derivative gains (losses) recorded in earnings (dollars in millions):



	Predecessor

Net losses recorded in earnings	$	(1,014	)

In connection with the UST Loan Agreement, Old GM granted warrants to the UST for 122 million shares of its common stock exercisable at $3.57 per share. Old GM recorded the warrants as a liability and recorded gains and losses related to this derivative in Interest income and other non-operating income, net. In connection with the 363 Sale, the UST returned the warrants and they were canceled.

Cash Flow Hedges

Old GM previously designated certain financial instruments as cash flow hedges to manage its exposure to certain foreign currency exchange risks.

The following table summarizes financial statement classification and amounts of gains (losses) that were reclassified from Accumulated other comprehensive income (loss) into earnings related to effective cash flow hedging relationships (dollars in millions):



	Predecessor
	January 1, 2009 Through July, 9, 2009
Automotive sales	$	(351	)
Automotive cost of sales	19
Reorganization gains, net	247
Net losses reclassified from Accumulated other comprehensive income (loss)	$	(85	)

The following table summarizes financial statement classification and amounts of gains (losses) that were reclassified from Accumulated other comprehensive income (loss) for cash flow hedges associated with previously forecasted transactions that subsequently became probable not to occur (dollars in millions):



	Predecessor
	January 1, 2009 Through July 9, 2009
Automotive sales	$	(182	)
Reorganization gains, net	247
Net gains reclassified from Accumulated other comprehensive income (loss)	$	65

Net Change in Accumulated Other Comprehensive Income (Loss)

The following table summarizes the net change in Accumulated other comprehensive income (loss) related to cash flow hedging activities (dollars in millions):



	Predecessor
	January 1, 2009 Through July 9, 2009
Beginning net unrealized loss on derivatives	$	(490	)
Reclassification to earnings	99
Ending net unrealized loss on derivatives	$	(391	)

In connection with our application of fresh-start reporting, the remaining previously deferred cash flow hedging gains and losses of $391 million in Accumulated other comprehensive income (loss) were adjusted to $0 at July 10, 2009.

Derivatives Not Meeting a Scope Exception from Fair Value Accounting

Old GM previously entered into purchase contracts that were accounted for as derivatives with changes in fair value recorded in Automotive cost of sales, as these contracts did not qualify for the normal purchases and normal sales scope exception in ASC 815. Certain of these contracts were terminated in the period January 1, 2009 through July 9, 2009. MLC retained the remainder of these purchase contracts in connection with the 363 Sale.

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 2029 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 28 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 years ranging from 2012 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, 2011 any proceeds we would receive from collateral were insignificant.

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 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, 2011 we estimate the remediation losses could range from $140 million to $310 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.

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; such escrow deposits may range from $530 million to $730 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, 2011. We believe that appropriate accruals have been established for such matters based on information currently available. Reserves for litigation losses are recorded in Accrued liabilities and Other liabilities and deferred income taxes. Litigation is inherently unpredictable, however, and unfavorable resolutions could occur. Accordingly, it is possible that an adverse outcome from such proceedings could exceed the amounts accrued in an amount that could be material to our financial condition, results of operations and cash flows in any particular reporting period.

Commencing on or about September 29, 2010, current and former hourly employees of GM Korea, our non-wholly owned consolidated subsidiary, filed six separate group actions in the Incheon District Court in Incheon, Korea. The cases allege that GM Korea failed to include certain allowances in its calculation of Ordinary Wages due under the Presidential Decree of the Korean Labor Standards Act. Although GM Korea intends to vigorously defend the claims asserted, at December 31, 2011 we have an accrual of 130 billion Korean Won (equivalent to $113 million) in connection with these cases. The current estimate of the value of plaintiffs' claims, if allowed in full, exceeds the accrual by 604 billion Korean Won (equivalent to $523 million) which represents the reasonably possible liability exposure. Both the scope of claims asserted and GM Korea's assessment of any or all of individual claim elements may change.

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. The current prospects for liability are uncertain, but because liability is not deemed probable, we have no accrual relating to this litigation. We cannot estimate the range of reasonably possible loss in the event of liability, as the case presents a variety of different legal theories, none of which GMCL believes are valid.

On April 6, 2010 the 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 New VEBA. The UAW alleges that we were contractually required to make this contribution. The reasonably possible loss as defined by ASC 450 “Contingencies” is $450 million, which is the amount claimed, but we believe that the claim is without merit and we have no accrual relating to this litigation. We filed a motion in the U.S. Bankruptcy Court for the Southern District of New York (Bankruptcy Court) asserting that the UAW's claim is barred by the Bankruptcy Court approved 2009 UAW Retiree Settlement Agreement and by other orders issued by the Bankruptcy Court that preclude additional GM contributions to the New VEBA. We also maintain that Delphi's bankruptcy plan of reorganization did not fulfill the applicable conditions of the relevant agreement and therefore payment would not be due even in the absence of the 2009 UAW Retiree Settlement Agreement. On August 23, 2011, the Bankruptcy Court issued an opinion abstaining from hearing the case, which will accordingly be litigated in Federal Court in U.S. District Court for the Eastern District of Michigan.

Liability Related to Contingently Issuable Shares

Under the Amended and Restated Master Sale and Purchase Agreement, as amended between us and Old GM and certain of its direct and indirect subsidiaries, we were obligated to issue additional shares of our common stock to MLC (Adjustment Shares) in the event that allowed general unsecured claims against MLC, as estimated by the Bankruptcy Court, exceed $35.0 billion. Following the dissolution of MLC on December 15, 2011, any Adjustment Shares we are obligated to issue will be issuable to the GUC Trust. The maximum number of Adjustment Shares issuable is 30 million shares (subject to adjustment to take into account stock dividends, stock splits and other transactions). The number of Adjustment Shares to be issued is calculated based on the extent to which estimated general unsecured claims exceed $35.0 billion with the maximum number of Adjustment Shares issued if estimated general unsecured claims total $42.0 billion or more. At December 31, 2011 and 2010 we concluded it was not probable that general unsecured claims would exceed $35.0 billion. We believe it is reasonably possible that general unsecured claims allowed against MLC will range between $32.5 billion and $36.0 billion.

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 $209 million and $193 million at December 31, 2011 and 2010 was pledged as collateral under the agreement. Through December 31, 2011 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, 2011 and 2010 accruals for asset retirement obligations were $99 million and $103 million.

Delphi Corporation

Benefit Guarantee

In 1999, Old GM spun-off Delphi Automotive Systems Corporation, which became Delphi. Prior to the consummation of the DMDA, Delphi was our and Old GM's largest supplier of automotive systems, components and parts, and we and Old GM were Delphi's largest customer. From 2005 to 2008 Old GM's annual purchases from Delphi ranged from approximately $6.5 billion to approximately $10.2 billion. At the time of the spin-off, employees of Delphi Automotive Systems Corporation became employees of Delphi, and Old GM entered into the Delphi Benefit Guarantee Agreements (DBGA) with the UAW, the International Union of Electronic, Electrical, Salaried, Machine and Furniture Workers – Communication Workers of America (IUE-CWA) and the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union (USW) providing contingent benefit guarantees whereby, under certain conditions, Old GM would make payments for certain pension and OPEB benefits to certain former U.S. hourly employees that became employees of Delphi. The DBGA provided that in the event that Delphi or its successor companies ceased doing business, terminated its pension plan or ceased to provide credited service or OPEB benefits at certain levels due to financial distress, Old GM could be liable to provide the corresponding benefits at the required level. With respect to pension benefits, the guarantee arises only to the extent the pension benefits Delphi and the PBGC provided fall short of the guaranteed amount.

In October 2005 Old GM received notice from Delphi that it was more likely than not that Old GM would become obligated to provide benefits pursuant to the DBGA, in connection with Delphi's commencement in October 2005 of Chapter 11 proceedings under the U.S. Bankruptcy Code (Bankruptcy Code).

Delphi-GM Settlement Agreements

In September 2007 and as amended at various times through September 2008, Old GM and Delphi entered into the Delphi-GM Settlement Agreements intended to: (1) resolve outstanding issues between Delphi and Old GM that arose before Delphi's emergence from its Chapter 11 proceedings; (2) govern certain aspects of Old GM's ongoing commercial relationship with Delphi; and (3) address a limited transfer of pension assets and liabilities, and the triggering of the benefit guarantees on the basis set forth in term sheets to the Delphi-GM Settlement Agreements.

The Amended Delphi-GM Settlement Agreements included Old GM's commitments to reimburse Delphi for certain: (1) employee benefit related costs, including OPEB and pension cost; (2) employee termination related costs; (3) ongoing labor costs; and (4) production and other facilitation related costs. In addition, Old GM committed to transfers, subject to certain conditions, of net liabilities from the Delphi Hourly Rate Plan to Old GM's U.S. hourly pension plan.

In September 2008 the Bankruptcy Court entered an order in Delphi's Chapter 11 proceedings approving the Amended Delphi-GM Settlement Agreements which then became effective. As a result of the September 2008 implementation of the Delphi-GM Settlement Agreements Old GM paid $1.0 billion to Delphi in the period January 1, 2009 through July 9, 2009 in settlement of amounts accrued to date against Old GM commitments. We paid $288 million in 2009 prior to the consummation of the DMDA in settlement of amounts accrued to date against our commitments.

Upon consummation of the DMDA, we settled and terminated commitments with limited exceptions under the Delphi-GM Settlement Agreements, and we and Delphi waived all claims against each other under the Delphi-GM Settlement Agreements.

IUE-CWA and USW Settlement Agreement

In September 2009 we entered into a settlement agreement with MLC, the IUE-CWA and the USW that resolved the DBGA with these unions. The agreement was approved by the Bankruptcy Court in November 2009.

Delphi Master Disposition Agreement

In July 2009 we, Delphi and the PBGC negotiated an agreement to be effective upon consummation of the DMDA regarding the settlement of PBGC's claims from the termination of the Delphi pension plans and the release of certain liens with the PBGC against Delphi's foreign assets. In return, the PBGC received a payment of $70 million from us and was granted a 100% interest in Class C Membership Interests in New Delphi which provide for the PBGC to participate in predefined equity distributions. We maintain the obligation to provide the difference between pension benefits paid by the PBGC according to regulation and those originally guaranteed by Old GM under the DBGA.

In October 2009 we consummated the transaction contemplated by the DMDA with Delphi, New Delphi, Old GM and other sellers and other buyers that are party to the DMDA, as more fully described in Note 4. Upon consummation of the DMDA we settled our commitments to Delphi accrued to date except for the obligation to provide the difference between pension benefits paid by the PBGC according to regulation and those originally guaranteed by Old GM under the DBGA that we continue to maintain.

Delphi Charges

The following table summarizes charges that have been recorded with respect to the various agreements with Delphi (dollars in millions):



	Successor		Predecessor
	July 10, 2009 Through December 31, 2009		January 1, 2009 Through July 9, 2009
Other automotive expenses, net	$	8	$	184
Automotive cost of sales	193		142
Reorganization gains, net	—		662
Total Delphi charges	$	201	$	988

These charges reflect the best estimate of obligations associated with the various Delphi agreements, including obligations under the DBGA, updated to reflect the DMDA. At July 9, 2009 these charges reflect the obligation to the PBGC upon consummation of the DMDA, consisting of the estimated fair value of the PBGC Class C Membership Interests in New Delphi of $317 million and the payment of $70 million due. Further, at July 9, 2009 these charges reflect an estimated value of $966 million pertaining to claims against Delphi that were waived upon consummation of the DMDA. The estimated value of the claims represents the excess after settlement of certain pre-existing commitments to Delphi of the fair value of Nexteer, the four domestic facilities and the investment in New Delphi over the cash consideration paid under the DMDA. Refer to Note 4 for additional information on the total consideration paid under the DMDA and the allocation of such consideration to the various units of account.

Provisions are made for estimated U.S. and non-U.S. income taxes, less available tax credits and deductions, which may be incurred on the remittance of our and Old GM's share of basis differences in investments in foreign subsidiaries and corporate joint ventures not deemed to be indefinitely reinvested. Taxes have not been provided on basis differences in investments in foreign subsidiaries and corporate joint ventures which are deemed indefinitely reinvested of $6.2 billion and $6.9 billion at December 31, 2011 and 2010. Quantification of the deferred tax liability, if any, associated with indefinitely reinvested earnings is not practicable.

In July 2009 Old GM recorded adjustments resulting in a net decrease in valuation allowances of $20.7 billion as a result of the 363 Sale and fresh-start reporting. The net decrease primarily resulted from U.S. federal and state tax attribute reduction of $12.2 billion related to debt cancellation income, a net difference of $5.5 billion between fresh-start reporting and historical U.S. GAAP bases of assets and liabilities at entities with valuation allowances, net valuation allowances of $1.7 billion associated with assets and liabilities retained by MLC, a foreign tax attribute reduction of $0.9 billion and release of valuation allowances of $0.7 billion. 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.

We and Old GM established or released the following significant valuation allowances as a result of a change in our evaluation of deferred tax asset realizability (dollars in millions):

Old GM accumulated pre-tax losses in the U.S. and various non-U.S. jurisdictions. These historical pre-tax losses were driven by several factors including but not limited to instability of the global economic environment, automotive price competition, relatively high cost structure, unfavorable commodity prices, unfavorable regulatory and tax environments and a challenging foreign currency exchange environment. By December 31, 2008, after weighing this objective and verifiable negative evidence with all other available positive and negative evidence, Old GM determined it was more likely than not it would not realize its deferred tax assets, and established valuation allowances for major jurisdictions including the U.S., Canada, Brazil, Australia, South Korea, Germany, Spain and the United Kingdom. Additional concerns arose related to the U.S. parent company's liquidity which led us to establish valuation allowances for Texas and various non-U.S. jurisdictions, even though many of these jurisdictions had historical profits and no other significant negative evidence factors.

In 2009 the U.S. parent company liquidity concerns were resolved in connection with the Chapter 11 Proceedings and the 363 Sale, and many non-U.S. jurisdictions, including Brazil, were generating and projecting taxable income. To the extent there were no other significant negative evidence factors, Old GM determined it was more likely than not it would realize its deferred tax assets and reversed valuation allowances in Brazil and various non-U.S. jurisdictions.

Although we have a short history as a new company, and our ability to achieve future profitability was enhanced by the cost and liability reductions that occurred as a result of the Chapter 11 Proceedings and 363 Sale, Old GM's historic operating results remain relevant as they are reflective of the industry and the effect of economic conditions. The fundamental businesses and inherent risks in which we globally operate did not change from those in which Old GM operated. As such, subsequent to the Chapter 11 Proceedings and the 363 Sale, due primarily to historical pre-tax losses, at December 31, 2011 we determined it was still more likely than not the deferred tax assets would not be realized in major jurisdictions including the U.S., Canada, South Korea, Germany, Spain and the United Kingdom. If additional positive evidence becomes available our conclusion regarding the need for full valuation allowances in these jurisdictions could change, resulting in the reversal of some or all of the valuation allowances.

At December 31, 2011 we determined in Australia it was more likely than not we would realize deferred tax assets in the future due primarily to sustained profitability and projected taxable income in an unlimited carryforward jurisdiction; accordingly, we reversed the valuation allowance in this jurisdiction.

Other Matters

Most of the tax attributes generated by Old GM and its domestic and foreign subsidiaries (net operating loss carryforwards and various income tax credits) survived the Chapter 11 Proceedings, and we are using or expect to use the tax attributes to reduce future tax liabilities. 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.

In the U.S., we have continuing responsibility for Old GM's open tax years. Old GM's federal income tax returns for 2007 and 2008 were audited by the Internal Revenue Service and the review was substantially concluded in the year ended December 31, 2011. 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 2011 with various significant tax jurisdictions. These open years contain matters that could be subject to differing interpretations of applicable tax laws and regulations as they relate to the amount, character, timing or inclusion of revenue and expenses or the sustainability of income tax credits for a given audit cycle. Given the global nature of our operations, there is a risk that transfer pricing disputes may arise.

In May 2009 the U.S. and Canadian governments resolved a transfer pricing matter for Old GM which covered the tax years 2001 through 2007. In the three months ended June 30, 2009 this resolution resulted in a tax benefit of $692 million and interest of $229 million. Final administrative processing of the Canadian case closing occurred in late 2009, and final administrative processing of the U.S. case closing occurred in February 2010.

In June 2010 a Mexican income tax audit covering the 2002 and 2003 tax years was concluded and an assessment of $146 million including tax, interest and penalties was issued. We believe we have adequate reserves established. Collection of any assessment will be suspended until a revised assessment is issued and during any subsequent proceedings through U.S. and Mexican competent authorities. We expect a revised assessment to be issued no earlier than March 2012.

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.

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

In the year ended December 31, 2011 certain issues were resolved relating to uncertain tax positions in jurisdictions which have 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.

At December 31, 2011 it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits in the next twelve months.

- Definition

Restructuring And Other Initiatives

Restructuring and Other Initiatives

Automotive

We have and Old GM had previously executed various restructuring and other initiatives, and we plan to execute additional initiatives in the future, if necessary, in order to align manufacturing capacity and other costs with prevailing global automotive production and to improve the utilization of remaining facilities. Related charges are recorded in Automotive cost of sales and Automotive selling, general and administrative expense.

The following 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 for GMNA, primarily relate to postemployment benefits to be paid.

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.

Our labor agreement includes cash severance incentive programs which may range up to $100 million through March 31, 2012 for skilled trade U.S. hourly employees that will be included in our restructuring liability upon irrevocable acceptances by both parties.

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. We expect to incur an additional $100 million to complete these programs, which will affect an additional 500 employees. To the extent these programs involve voluntary separations, no liabilities are recorded until offers to employees are accepted. If employees are involuntarily terminated, a liability is recorded at the communication date.

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. Liabilities were recorded as offers to the employees were irrevocably accepted.

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.

Period July 10, 2009 through December 31, 2009

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


•	The restructuring reserves were increased by $213 million due to an increase in the SUB and TSP accrual of $183 million related to capacity actions, productivity initiatives, acquisition of Nexteer and four domestic facilities and Canadian restructuring activities of $30 million.


•	The salaried and hourly workforce severance accruals were reduced by $146 million as a result of elections subsequently made by terminating employees. Such amounts were reclassified as special termination benefits and were funded from the U.S. defined benefit pension plans and other applicable retirement benefit plans.

GME recorded charges, interest accretion and other, and revisions to estimates primarily related to separation charges for early retirement programs and additional liability adjustments, primarily in Germany.

GMIO recorded charges, interest accretion and other, and revisions to estimates primarily related to separation charges of $72 million for restructuring programs in Australia for salaried and hourly employees.

(a)	The remaining cash payments related to these reserves for restructuring and other initiatives, including temporary layoff benefits for GMNA, primarily relate to postemployment benefits to be paid.

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


•	Postemployment benefit charges in the U.S. of $825 million related to 13,000 hourly employees who participated in the 2009 special attrition programs.


•	SUB and TSP related charges in the U.S. of $707 million, recorded as an additional liability determined by an actuarial analysis at the implementation of the SUB and TSP and related suspension of the JOBS Program.

•

Revisions to estimates of $401 million to decrease the reserve, primarily related to $335 million for the suspension of the JOBS Program and $141 million for estimated future wages and benefits due to employees who participated in the 2009 special attrition programs; offset by a net increase of $86 million related to Canadian salaried workforce reductions and other restructuring initiatives in Canada.


•	Separation charges of $250 million for a U.S. salaried severance program to allow 6,000 terminated employees to receive ongoing wages and benefits for up to 12 months.


•	Postemployment benefit charges in Canada of $38 million related to 380 hourly employees who participated in a special attrition program.

GMIO recorded charges, interest accretion and other, and revisions to estimates primarily related to separation charges in Australia of $19 million related to a facility idling. The program affects employees who left through December 2009.

GMSA recorded charges, interest accretion and other, and revisions to estimates related to voluntary and involuntary separation programs in South America affecting 3,300 salaried and hourly employees.

Preferred Stock

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



					Successor
	Liquidation Preference Per Share		Dividend Rate Per Annum		Dividends Paid
	Liquidation Preference Per Share		Dividend Rate Per Annum		Year Ended December 31, 2011		Year Ended December 31, 2010		July 10, 2009 Through December 31, 2009
Series A Preferred Stock	$	25.00	9.00	%	$	621	$	810	$	349
Series B Preferred Stock	$	50.00	4.75	%	$	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 $0.7 billion recorded in Cumulative dividends on and charge related to purchase of 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. These anti-dilution provisions provide a holder of the Series B Preferred Stock 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. 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. Refer to Note 26 for a description of the effect of the two-class method on earnings per share.

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, four million shares for exercised warrants, and 500 thousand shares for the settlement of salary and other restricted stock awards. In the year ended December 31, 2010 we issued 100 thousand shares of restricted common stock.

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 been substantially distributed to creditors of Old GM 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. In April 2011 MLC began distribution of its warrants for our common stock to its unsecured creditors. 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 New VEBA warrants are exercisable at any time prior to December 31, 2015 at an exercise price of $42.31 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, 2011 and 2010 is 313 million and 318 million.

Noncontrolling Interests

In October 2009 we completed our participation in an equity rights offering in GM Korea for $417 million. As a result of the participation in the equity rights offering our ownership interest in GM Korea increased from 50.9% to 70.1%. In March 2011 we completed the acquisition of an additional 6.9% in GM Korea. After completing this transaction we now own 77.0% of the outstanding shares.

In December 2009 we acquired the remaining noncontrolling interest of a joint venture for $100 million increasing our ownership interest from 50% to 100%. This transaction resulted in no charge to Capital surplus.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings (Loss) Per Share

In the year ended December 31, 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 period ended December 31, 2011.

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

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

__________


(a)	Includes earned but undeclared dividends of $26 million, $26 million and $34 million on our Series A Preferred Stock and $20 million, $25 million and $0 on our Series B Preferred Stock in the years ended December 31, 2011 and 2010 and in the period July 10, 2009 through December 31, 2009.

(b)

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; 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; and cumulative dividends on preferred stock of $131 million in the period July 10, 2009 through December 31, 2009, which excludes dividends of $252 million which were paid to the New VEBA prior to December 31, 2009, as these shares were not considered outstanding until December 31, 2009 due to the terms of the 2009 UAW Retiree Settlement Agreement. Payments made to the New VEBA were recorded as employer contributions and included in Net income (loss) attributable to stockholders.

(c)

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; 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; and cumulative dividends on preferred stock of $131 million in the period July 10, 2009 through December 31, 2009.

Year Ended December 31, 2011

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. 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. Refer to Note 25 for a description of the Series B Preferred Stock and the application of the two-class method.

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.

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, 2011, of which 46 million shares were not included in the computation of diluted earnings per share because the warrants' exercise price was greater than the average market price of the common shares. Under the treasury stock method, the assumed exercise of the remaining warrants resulted in 130 million dilutive shares.

Diluted earnings per share included the effect of 13 million unvested RSUs granted to certain global executives. The Adjustment Shares were excluded from the computation of basic and diluted earnings per share as the condition that would result in the issuance of the Adjustment Shares was not satisfied.

In July 2011 the 61 million shares of common stock contributed to our pension plans in January 2011 met the criteria to qualify as plan assets for accounting purposes. These shares were 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. The Adjustment Shares were excluded from the computation of basic and diluted earnings per share as the condition that would result in the issuance of the Adjustment Shares was not satisfied.

Period July 10, 2009 through December 31, 2009

Outstanding warrants to purchase 272 million shares of common stock were not included in the computation of diluted loss per share because the effect would have been antidilutive and 1 million RSUs were excluded from the computation of diluted loss per share as these awards were payable in cash during that time. The Adjustment Shares were excluded from the computation of basic and diluted loss per share as the condition that would result in the issuance of the Adjustment Shares was not satisfied.

Old GM

Period January 1, 2009 through July 9, 2009

Diluted earnings per share included the potential effect of the assumed exercise of certain stock options. Old GM excluded 208 million stock options and warrants in the computation of diluted earnings per share because the exercise price was greater than the average market price of the common shares. No shares potentially issuable to satisfy the in-the-money amount of Old GM's convertible debentures were included in the computation of diluted earnings per share as the conversion options in various series of convertible debentures were not in the money.

Long-Term Incentive Plan

We granted 5 million and 15 million RSUs valued at the grant date fair value of our common stock in the years ended December 31, 2011 and 2010 and no RSUs in the period July 10, 2009 through December 31, 2009. These awards granted either cliff vest or ratably vest generally over a three-year service period, as defined in the terms of each award. We have elected to record compensation cost for these awards on a straight-line basis over the entire vesting period. Our policy is to issue new shares upon settlement of RSUs.

The 2011 awards granted to the Top 25 highest compensated employees will settle three years from the grant date in 25% increments in conjunction with each 25% of our Troubled Asset Relief Program (TARP) obligations that are repaid. The awards for the Next 75 highest compensated employees will settle either: (1) three years from the date of grant; or (2) on the first and third anniversary dates of grant. The awards to the non-Top 100 highest compensated employees will settle on the first, second and third anniversary dates of grant. Vesting and subsequent settlement will generally occur based upon employment at the end of each specified service period.

The 2010 awards granted to the Top 25 highest compensated employees will settle three years from the grant date in 25% increments in conjunction with each 25% of our TARP obligations that are repaid. The awards for the non-top 25 highest compensated employees will settle after three years in 25% increments in conjunction with each 25% of the U.S. and Canadian government loans that are repaid. The U.S. and Canadian government loans were fully repaid in April 2010, thus these awards will be settled upon completion of the remaining three year service period.

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. Compensation cost for these employees is recognized on a straight-line basis over the requisite service period.

Salary Stock

In November 2009 we initiated a salary stock program whereby a portion of each participant's total annual compensation was accrued and converted to RSUs at each salary payment date. In the years ended December 31, 2011 and 2010 a portion of each participant's salary accrued on each salary payment date converted to RSUs on a quarterly basis. The awards are fully vested and nonforfeitable upon grant therefore compensation cost is fully recognized on the date of grant. The awards are settled quarterly over a three year period commencing on the first anniversary date of grant. Our policy is to issue new shares upon settlement of these awards.

RSUs

Prior to our public offering, all RSU awards were classified as liability awards as they were payable in cash. In November 2010 we reclassified all of the RSU liability awards to equity for those awards that became payable in shares in accordance with the plan terms.

The following table summarizes information about our RSUs under the 2009 GMLTIP and GMSSP (RSUs in millions):



	Successor
	Shares		Weighted- Average Grant Date Fair Value		Weighted-Average Remaining Contractual Term
RSUs outstanding at December 31, 2010	17.2		$	19.03	1.8
Granted	7.6		$	31.18

RSUs unvested and expected to vest at December 31, 2011	14.0		$	23.47	1.5
RSUs vested and payable at December 31, 2011	8.1		$	22.07	—
RSUs granted in the year ended December 31, 2010			$	19.17
RSUs granted in the period July 10, 2009 through December 31, 2009			$	16.39

We recorded compensation expense of $233 million, $235 million and $23 million for our stock incentive plans in the years ended December 31, 2011 and 2010 and in the period July 10, 2009 through December 31, 2009. The compensation cost of each RSU granted under the 2009 GMLTIP and GMSSP that will be settled in equity is based on the fair value of our common stock on the date of grant or, for those RSUs reclassified from liability to equity-based awards, the fair value of our common stock as of the date of the public offering.

At December 31, 2011 the total unrecognized compensation expense for nonvested equity awards granted under the 2009 GMLTIP was $263 million. This expense is expected to be recorded over a weighted-average period of 1.5 years.

The total fair value of RSUs vested was $105 million, $78 million and $19 million in the years ended December 31, 2011 and 2010 and in the period July 10, 2009 through December 31, 2009.

Old GM

Old GM had various stock incentive plans which were administered by either its Executive Compensation Committee of its Board of Directors or its Vice President of Human Resources. Stock incentive awards consisted of stock options, market-contingent stock options, stock performance awards and cash-based RSUs. Stock incentive awards, some of which were subject to performance conditions, were granted at fair value and were subject to various vesting conditions. In connection with the 363 Sale, MLC retained the responsibility for administering Old GM's stock incentive plans. We have recorded no compensation expense related to Old GM's stock incentive plans subsequent to July 9, 2009.

__________

(a)

Represents liabilities (receivables) recorded and maximum obligations for agreements entered into prior to December 31, 2008. Agreements entered into after December 31, 2008 have not included residual support or risk sharing programs. In the years ended December 31, 2011 and 2010 favorable adjustments to our residual support and risk sharing liabilities of $0.5 billion and $0.6 billion were recorded in the U.S. due to increases in estimated residual values.


(b)	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.

	Year Ended December 31, 2011		Year Ended December 31, 2010		July 10, 2009 Through December 31, 2009		January 1, 2009 Through July 9, 2009
U.S. marketing incentives and operating lease residual payments	$	1,428	$	1,111	$	695	$	601
Exclusivity fee income	$	76	$	99	$	47	$	52

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 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 24, 2013 we will have the right to offer retail financing incentive programs through any third party financing source, including Ally Financial, without any restrictions or limitations.

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, ends in August 2012 for vehicles invoiced through August 2011 and ends in August 2013 for vehicles invoiced through August 2012.

The maximum potential amount of future payments 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.

Segment Reporting [Abstract]

Segment Reporting

Consolidated

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, and evaluates GM Financial through Income (loss) 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	• GMC	• Opel
• Cadillac	• Daewoo	• Holden	• Vauxhall

At December 31, 2011 we also had equity ownership stakes directly or indirectly in entities through various regional subsidiaries, including GM Korea, SGM, SGMW, FAW-GM and HKJV. These companies design, manufacture and market vehicles under the following brands:



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

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

All intersegment balances and transactions have been eliminated in consolidation.

Chapter 11 Proceedings and the 363 Sale

Background

Over time as Old GM’s market share declined in North America, Old GM needed to continually restructure its business operations to reduce cost and excess capacity. Legacy labor costs and obligations and capacity in its dealer network made Old GM less competitive than new entrants into the U.S. market. These factors continued to strain Old GM’s liquidity. In 2005 Old GM incurred significant losses from operations and from restructuring activities such as providing support to Delphi and other efforts intended to reduce operating costs. Old GM managed its liquidity during this time through a series of cost reduction initiatives, capital markets transactions and sales of assets. However, the global credit market crisis had a dramatic effect on Old GM and the automotive industry. In the second half of 2008, the increased turmoil in the mortgage and overall credit markets (particularly the lack of financing for buyers or lessees of vehicles), the continued reductions in U.S. housing values, the volatility in the price of oil, recessions in the U.S. and Western Europe and the slowdown of economic growth in the rest of the world created a substantially more difficult business environment. The ability to execute capital markets transactions or sales of assets was extremely limited, vehicle sales in North America and Western Europe contracted severely and the pace of vehicle sales in the rest of the world slowed. Old GM’s liquidity position, as well as its operating performance, were negatively affected by these economic and industry conditions and by other financial and business factors, many of which were beyond its control.

As a result of these economic conditions and the rapid decline in sales in the three months ended December 31, 2008 Old GM determined that, despite the actions it had then taken to restructure its U.S. business, it would be unable to pay its obligations in the normal course of business in 2009 or service its debt in a timely fashion, which required the development of a new plan that depended on financial assistance from the U.S. government.

In December 2008 Old GM requested and received financial assistance from the U.S. government and entered into the UST Loan Agreement. In early 2009 Old GM’s business results and liquidity continued to deteriorate, and, as a result, Old GM obtained additional funding from the UST under the UST Loan Agreement. Old GM also received funding from EDC under the EDC Loan Facility.

As a condition to obtaining the loans under the UST Loan Agreement, Old GM was required to submit a plan in February 2009 that included specific actions (Viability Plan) intended to result in the following:


•	Repayment of all loans, interest and expenses under the UST Loan Agreement, and all other funding provided by the U.S. government;


•	Compliance with federal fuel efficiency and emissions requirements and commencement of domestic manufacturing of advanced technology vehicles;


•	Achievement of a positive net present value, using reasonable assumptions and taking into account all existing and projected future costs;


•	Rationalization of costs, capitalization and capacity with respect to its manufacturing workforce, suppliers and dealerships; and


•	A product mix and cost structure that is competitive in the U.S. marketplace.

The UST Loan Agreement also required Old GM to, among other things, use its best efforts to achieve the following restructuring targets: (1) debt reduction of at least two-thirds; (2) labor modifications to achieve an average compensation competitive with that of foreign-owned U.S. domiciled automakers; and, (3) modification of certain retiree healthcare obligations.

The UST Loan Agreement provided that if, by March 31, 2009 or a later date (not to exceed 30 days after March 31, 2009) as determined by the Presidential Task Force on the Auto Industry (Auto Task Force) (Certification Deadline), the Auto Task Force had not certified that Old GM had taken all steps necessary to achieve and sustain its long-term viability, international competitiveness and energy efficiency in accordance with the Viability Plan, then the loans and other obligations under the UST Loan Agreement were to become due and payable on the thirtieth day after the Certification Deadline.

On March 30, 2009 the Auto Task Force determined that the plan was not viable and required substantial revisions. On March 31, 2009 Old GM and the UST agreed to postpone the Certification Deadline to June 1, 2009. Old GM made further modifications to its Viability Plan in an attempt to satisfy the Auto Task Force requirement that it undertake a substantially more accelerated and aggressive restructuring plan (Revised Viability Plan), the most significant of which included reducing Old GM's indebtedness and VEBA obligations.

Chapter 11 Proceedings

Old GM was not able to complete the cost reduction and restructuring actions in its Revised Viability Plan, including the debt reductions and VEBA modifications, which resulted in extreme liquidity constraints. As a result, on June 1, 2009 Old GM and certain of its direct and indirect subsidiaries sought relief through Chapter 11 Proceedings of the Bankruptcy Code in the Bankruptcy Court.

In connection with the Chapter 11 Proceedings, Old GM entered into the DIP Facility and received additional funding commitments from EDC to support Old GM's Canadian operations.

The following table summarizes the total funding and funding commitments Old GM received from the U.S. and Canadian governments and the additional notes Old GM issued related thereto in the period December 31, 2008 through July 9, 2009 (dollars in millions):



	Predecessor

DIP Facility	33,300		2,221		35,521
Total	$	59,355	$	3,554	$	62,909

__________


(a)	Old GM did not receive any proceeds from the issuance of these promissory notes, which were issued as additional compensation to the UST and EDC.


(b)	Includes debt of $361 million, which the UST loaned to Old GM under the warranty program.


(c)	Includes approximately $2.4 billion from the EDC Loan Facility received in the period January 1, 2009 through July 9, 2009 and funding commitments of $3.9 billion that were immediately converted into our equity. This funding was received on July 15, 2009.

363 Sale

On July 10, 2009 we completed the acquisition of substantially all of the assets and assumed certain liabilities of Old GM and certain of its direct and indirect subsidiaries (collectively, the Sellers). The 363 Sale was consummated in accordance with a purchase agreement also referred to as the Amended and Restated Master Sale and Purchase Agreement, dated June 26, 2009, as amended, between us and the Sellers, and pursuant to the Bankruptcy Court's sale order dated July 5, 2009.

In connection with the 363 Sale, the purchase price paid to Old GM was composed of:

•

A credit bid in an amount equal to the total of: (1) debt of $19.8 billion under Old GM's UST Loan Agreement, plus notes of $1.2 billion issued as additional compensation for the UST Loan Agreement, plus interest on such debt Old GM owed as of the closing date of the 363 Sale; and (2) debt of $33.3 billion under Old GM's DIP Facility, plus notes of $2.2 billion issued as additional compensation for the DIP Facility, plus interest Old GM owed as of the closing date, less debt of $8.2 billion owed under the DIP Facility;


•	The UST's return of the warrants Old GM previously issued to it;


•	The issuance to MLC of shares of our common stock and warrants to acquire newly issued shares of our common stock as presented in the table in the following section entitled "Issuance of Common Stock, Preferred Stock and Warrants;" and


•	Our assumption of certain specified liabilities of Old GM (including debt of $7.1 billion owed under the DIP Facility).

Under the terms of the 363 Sale agreement, we are obligated to issue Adjustment Shares to the GUC Trust following the dissolution of MLC in the event that allowed general unsecured claims against MLC, as approved by the Bankruptcy Court, exceed $35.0 billion. Refer to Note 20 for a description of the contingently issuable Adjustment Shares.

Agreements with the UST, EDC and New VEBA

On July 10, 2009 we entered into the UST Credit Agreement and assumed debt of $7.1 billion maturing on July 10, 2015 that Old GM incurred under its DIP Facility. Immediately after entering into the UST Credit Agreement, we made a partial prepayment, reducing the UST Credit Agreement principal balance to $6.7 billion. We issued VEBA Notes in the principal amount of $2.5 billion to the New VEBA. Through our wholly-owned subsidiary GMCL we also entered into the Canadian Loan with EDC, as a result of which GMCL had a $1.3 billion term loan.

In December 2009 and March 2010 we made quarterly payments of $1.0 billion and $1.0 billion on the UST Credit Agreement and GMCL made quarterly payments of $192 million and $194 million on the Canadian Loan. In April 2010, we used funds from our escrow account to repay in full the outstanding amount of the UST Credit Agreement of $4.7 billion, and GMCL repaid in full the outstanding amount of the Canadian Loan of $1.1 billion. Both loans were repaid prior to maturity. In October 2010 we repaid in full the outstanding amount (together with accreted interest thereon) of the VEBA Notes of $2.8 billion.

Refer to Note 17 for additional information on the UST Credit Agreement, VEBA Notes and the Canadian Loan.

Issuance of Common Stock, Preferred Stock and Warrants

On July 10, 2009 we issued the following securities to the UST, Canada GEN Investment Corporation, a corporation organized under the laws of Canada (Canada Holdings), the New VEBA and MLC (shares in millions):



	Successor
	Common Stock	Series A Preferred Stock(b)
	Common Stock	Series A Preferred Stock(b)
UST	912	84
Canada Holdings	175	16
New VEBA(a)	263	260
MLC(a)	150	—
	1,500	360

__________


(a)	New VEBA also received a tranche of warrants to acquire 46 million shares of our common stock and MLC received two tranches of warrants, each to acquire 136 million shares of our common stock. Refer to Note 25 for additional description of warrants.


(b)	Refer to Note 25 for a description of the Series A Preferred Stock.

Additional Modifications to Pension and Other Postretirement Plans Contingent upon the Completion of the 363 Sale

We modified the U.S. hourly pension plan, the U.S. executive retirement plan, the U.S. salaried life plan, the non-UAW hourly retiree medical plan and the U.S. hourly life plan. These modifications became effective upon the completion of the 363 Sale. Refer to Note 18 for description of the changes to these plans.

Accounting for the Effects of the Chapter 11 Proceedings and the 363 Sale

Chapter 11 Proceedings

ASC 852, “Reorganizations,” (ASC 852) is applicable to entities operating under Chapter 11 of the Bankruptcy Code. ASC 852 generally does not affect the application of U.S. GAAP that we and Old GM followed to prepare the consolidated financial statements, but it does require specific disclosures for transactions and events that were directly related to the Chapter 11 Proceedings and transactions and events that resulted from ongoing operations.

Old GM prepared its consolidated financial statements in accordance with the guidance in ASC 852 in the period June 1, 2009 through July 9, 2009. Revenues, expenses, realized gains and losses, and provisions for losses directly related to the Chapter 11 Proceedings were recorded in Reorganization gains, net. Reorganization gains, net do not constitute an element of operating loss due to their nature and due to the requirement of ASC 852 that they be reported separately. Cash amounts provided by or used in the Chapter 11 Proceedings are separately disclosed in the statement of cash flows.

Application of Fresh-Start Reporting

The Bankruptcy Court did not determine a reorganization value in connection with the 363 Sale. Reorganization value is defined as the value of our assets without liabilities. In order to apply fresh-start reporting, ASC 852 requires that total postpetition liabilities and allowed claims be in excess of reorganization value and prepetition stockholders receive less than 50.0% of our common stock. Based on our estimated reorganization value, we determined that on July 10, 2009 both the criteria of ASC 852 were met and, as a result, we applied fresh-start reporting.

363 Sale and Fresh-Start Reporting Adjustments

The following table summarizes Old GM's Reorganization gains, net, arising from the 363 Sale and fresh-start reporting (dollars in millions):



	Predecessor
	January 1, 2009 Through July 9, 2009

- Definition

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

- Definition

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