Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies [Text Block]	Organization and Summary of Significant Accounting Policies General Dana Holding Corporation (Dana) is headquartered in Maumee, Ohio and was incorporated in Delaware in 2007. As a global provider of high technology driveline (axles, driveshafts and transmissions), sealing and thermal-management products our customer base includes virtually every major vehicle manufacturer in the global light vehicle, medium/heavy vehicle and off-highway markets. The terms "Dana," "we," "our" and "us," when used in this report are references to Dana. These references include the subsidiaries of Dana unless otherwise indicated or the context requires otherwise. Summary of significant accounting policies Basis of presentation — Our consolidated financial statements include the accounts of all subsidiaries where we hold a controlling financial interest. The ownership interests in subsidiaries held by third parties are presented in the consolidated balance sheet within equity, but separate from the parent’s equity, as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in 20 to 50%-owned affiliates, which are not required to be consolidated, are generally accounted for under the equity method. Equity in earnings of these investments is presented separately in the consolidated statement of operations, net of tax. Investments in less-than-20%-owned companies are generally included in the financial statements at the cost of our investment. Dividends, royalties and fees from these cost basis affiliates are recorded in income when received. In the first quarter of 2015, we identified an error attributable to the calculation of noncontrolling interests net income of a subsidiary. The error resulted in an understatement of noncontrolling equity and noncontrolling interests net income and a corresponding overstatement of parent company stockholders' equity and net income attributable to the parent company in prior periods. Based on our assessments of qualitative and quantitative factors, the error and related impacts were not considered material to the financial statements of the prior periods to which they relate. The error was corrected in March 2015 by increasing noncontrolling interests net income by $9. The correction was not considered material to our 2015 net income attributable to the parent company. In the third quarter of 2014, we identified an error that had resulted in a $10 overstatement of the values assigned to our defined benefit pension obligation and goodwill when we applied fresh start accounting in 2008. These overstatements affected pension expense, other comprehensive income and impairment of goodwill in subsequent periods. Based on our assessments of qualitative and quantitative factors, the error and the related impacts were not considered material to the financial statements for the quarter ended September 30, 2014 or the prior periods to which they relate. The error was corrected in September 2014 by decreasing pension and postretirement obligations by $17, decreasing accumulated other comprehensive loss by $3 to eliminate the related impacts on unrecognized pension expense and currency translation adjustments, decreasing goodwill by $3, decreasing cost of sales by $5 to reverse the cumulative impact on pension expense and crediting other income, net for $6 to effectively reverse a portion of the goodwill impairment recognized in 2008. Held for sale — We classify long-lived assets or disposal groups as held for sale in the period: management commits to a plan to sell; the long-lived asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such long-lived assets or disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell have been initiated; the sale is probable within one year; the asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Long-lived assets and disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. See Note 2 for additional information regarding the disposal group held for sale at the end of 2014 and divested in January 2015. Discontinued operations — Prior to January 1, 2015, we would classify a business component that had been disposed of or classified as held for sale as discontinued operations if the cash flows of the component were eliminated from our ongoing operations and we no longer had any significant continuing involvement in or with the component. The results of operations of our discontinued operations, including any gains or losses on disposition, were aggregated and presented on one line in the income statement. See Recently adopted accounting pronouncements in this note for a description of the current practice and Note 2 for additional information regarding our discontinued operations. Estimates — Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP), which require the use of estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. We believe our assumptions and estimates are reasonable and appropriate. However, due to the inherent uncertainties in making estimates, actual results could differ from those estimates. Fair value measurements — A three-tier fair value hierarchy is used to prioritize the inputs to valuation techniques used to measure fair value. The three levels of inputs are as follows: Level 1 inputs (highest priority) include unadjusted quoted prices in active markets for identical instruments. Level 2 inputs include quoted prices for similar instruments that are observable either directly or indirectly. Level 3 inputs (lowest priority) include unobservable inputs in which there is little or no market data, which require management to develop its own assumptions. Classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The inputs we use in our valuation techniques include market data or assumptions that we believe market participants would use in pricing an asset or liability, including assumptions about risk when appropriate. Our valuation techniques include a combination of observable and unobservable inputs. When available, we use quoted market prices to determine the fair value (market approach). In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, we consider the amount and timing of estimated future cash flows and assumed discount rates reflecting varying degrees of credit risk that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date (income approach). Fair values may not represent actual values of the financial instruments that could be realized as of the balance sheet date or that will be realized in the future. Cash and cash equivalents — Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have maturities of three months or less when purchased. Marketable securities — Our investments in marketable securities reported in the accompanying balance sheet are classified as available for sale and carried at fair value. Unrealized gains and losses are recorded in accumulated other comprehensive income (loss) (AOCI) until realized. Realized gains and losses are recorded using the specific identification method. Inventories — Inventories are valued at the lower of cost or market. Cost is determined using the average or first-in, first-out (FIFO) cost method. Property, plant and equipment — As a result of our adoption of fresh start accounting on February 1, 2008, property, plant and equipment was stated at fair value with useful lives ranging from two to thirty years. Useful lives of newly acquired assets are generally twenty to thirty years for buildings and building improvements, five to ten years for machinery and equipment, three to five years for tooling and office equipment and three to ten years for furniture and fixtures. Depreciation is recognized over the estimated useful lives using primarily the straight-line method for financial reporting purposes and accelerated depreciation methods for federal income tax purposes. If assets are impaired, their value is reduced via an increase in accumulated depreciation. Pre-production costs related to long-term supply arrangements — The costs of tooling used to make products sold under long-term supply arrangements are capitalized as part of property, plant and equipment and amortized over their useful lives if we own the tooling or if we fund the purchase but our customer owns the tooling and grants us the irrevocable right to use the tooling over the contract period. If we have a contractual right to bill our customers, costs incurred in connection with the design and development of tooling are carried as a component of other accounts receivable until invoiced. Design and development costs related to customer products are deferred if we have an agreement to collect such costs from the customer; otherwise, they are expensed when incurred. At December 31, 2015, the machinery and equipment component of property, plant and equipment includes $3 of our tooling related to long-term supply arrangements, while trade and other accounts receivable includes $27 of costs related to tooling that we have a contractual right to collect from our customers. Goodwill — We test goodwill for impairment annually as of October 31 and more frequently if events occur or circumstances change that would warrant an interim review. Goodwill impairment testing is performed at the reporting unit level, which is our operating segment. We estimate the fair value of the reporting unit in the first step using various valuation methodologies, including projected future cash flows and multiples of current earnings. If the estimated fair value of the reporting unit exceeds its carrying value, the goodwill is considered not impaired. If the carrying value of the reporting unit exceeds its estimated fair value, then the second step of the test would be required to determine the implied fair value of the goodwill and any resulting impairment. Our goodwill is assigned to our Off-Highway segment. The estimated fair value of our Off-Highway reporting unit was significantly greater than its carrying value at October 31, 2015. No impairment of goodwill occurred during the three years ended December 31, 2015. Intangible assets — Intangible assets include the value of core technology, trademarks and trade names, customer relationships and intangible assets used in research and development activities. Core technology and customer relationships have definite lives while intangible assets used in research and development activities and substantially all of our trademarks and trade names have indefinite lives. Definite-lived intangible assets are amortized over their useful life using the straight-line method of amortization and are periodically reviewed for impairment indicators. Amortization of core technology is charged to cost of sales. Amortization of trademarks and trade names and customer relationships is charged to amortization of intangibles. Intangible assets used in research and development activities have an indefinite life until completion of the associated research and development efforts. Upon completion of development, the assets are amortized over their useful life; if the project is abandoned, the assets are written off immediately. Indefinite-lived intangible assets are tested for impairment annually and more frequently if impairment indicators exist. See Notes 2 and 3 for more information about intangible assets. Investments in affiliates — Investments in affiliates include investments accounted for under the equity and cost methods. We monitor our investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis in accordance with GAAP. Indicators include, but are not limited to, current economic and market conditions, operating performance of the affiliate, including current earnings trends and undiscounted cash flows, and other affiliate-specific information. If we determine that an other-than-temporary decline in value has occurred, we recognize an impairment loss, which is measured as the excess of the investment's recorded carrying value over its fair value. The fair value determination, particularly for investments in privately-held companies, requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and determination of whether any identified impairment is other than temporary. See Note 19 for further information about our investment in affiliates. Tangible asset impairments — We review the carrying value of amortizable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the undiscounted future net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of are reported at the lower of their carrying amount or fair value less costs to sell and are no longer depreciated. Other long-lived assets and liabilities — We discount our workers’ compensation and asbestos liabilities and the related amounts recoverable from insurers by applying blended risk-free rates that are appropriate for the duration of the projected cash flows. The use of risk-free rates is considered appropriate given that other risks affecting the volume and timing of payments have been considered in developing the probability-weighted projected cash flows. The blended risk-free rates are revised annually to consider incremental cash flow projections. Financial instruments — The carrying values of cash and cash equivalents, trade receivables and short-term borrowings approximate fair value. Notes receivable are carried at fair value, which considers the contractual call or selling price, if applicable. Borrowings under our credit facilities are carried at historical cost and adjusted for principal payments and foreign currency fluctuations. Derivatives — Foreign currency forward contracts and currency swaps are carried at fair value. We enter into these contracts to manage our exposure to the impact of currency fluctuations on certain foreign currency-denominated assets and liabilities and on a portion of our forecasted purchase and sale transactions. On occasion, we also enter into net investment hedges to protect the translated U.S. dollar value of our investment in certain foreign subsidiaries. Changes in the fair value of currency-related contracts treated as cash flow hedges are deferred and included as a component of other comprehensive income (loss) (OCI) to the extent the contracts remain effective and the associated forecasted transactions remain probable. Effectiveness is measured by using regression analysis to determine the degree of correlation between the change in the fair value of the derivative instrument and the change in the associated foreign currency exchange rates. Deferred gains and losses are reclassified to other income, net in the same periods in which the underlying transactions affect earnings. Changes in the fair value of contracts not treated as cash flow hedges or as net investment hedges are recognized in other income, net in the period in which those changes occur. Changes in the fair value of contracts treated as net investment hedges are recorded in the cumulative translation adjustment (CTA) component of OCI. Amounts recorded in CTA are deferred until such time as the investment in the associated subsidiary is substantially liquidated. We may also use interest rate swaps to manage exposure to fluctuations in interest rates and to adjust the mix of our fixed-rate and variable-rate debt. With our current portfolio of fixed-rate debt, we occasionally execute a fixed-to-floating interest rate swap which serves to convert our fixed-rate debt to variable-rate debt. As a fair value hedge of the underlying debt, changes in the fair values of the swap and the underlying debt are recorded in interest expense. We do not use derivatives for trading or speculative purposes and we do not hedge all of our exposures. Environmental compliance and remediation — Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to existing conditions caused by past operations that do not contribute to our current or future revenue generation are expensed. Liabilities are recorded when environmental assessments and/or remedial efforts are probable and the costs can be reasonably estimated. We consider the most probable method of remediation, current laws and regulations and existing technology in determining our environmental liabilities. Pension and other postretirement defined benefits — Net pension and postretirement benefits expenses and the related liabilities are determined on an actuarial basis. These plan expenses and obligations are dependent on management’s assumptions developed in consultation with our actuaries. We review these actuarial assumptions at least annually and make modifications when appropriate. With the input of independent actuaries and other relevant sources, we believe that the assumptions used are reasonable; however, changes in these assumptions, or experience different from that assumed, could impact our financial position, results of operations or cash flows. Postemployment benefits — Costs to provide postemployment benefits to employees are accounted for on an accrual basis. Obligations that do not accumulate or vest are recorded when payment is probable and the amount can be reasonably estimated. For those obligations that accumulate or vest and the amount can be reasonably estimated, expense and the related liability are recorded as service is rendered. Equity-based compensation — We measure compensation cost arising from the grant of share-based awards to employees at fair value. We recognize such costs in income over the period during which the requisite service is provided, usually the vesting period. The grant date fair value is estimated using valuation techniques that require the input of management estimates and assumptions. We believe that the assumptions used are reasonable; however, due to inherent uncertainties in making estimates, if other assumptions had been used, it could have impacted our financial position and results of operations. Revenue recognition — Sales are recognized when products are shipped and risk of loss has transferred to the customer. We accrue for warranty costs, sales returns and other allowances based on experience and other relevant factors when sales are recognized. Adjustments are made as new information becomes available. Shipping and handling fees billed to customers are included in sales, while costs of shipping and handling are included in cost of sales. Taxes collected from customers are excluded from revenues and credited directly to obligations to the appropriate governmental agencies. Foreign currency translation — The financial statements of subsidiaries and equity affiliates outside the U.S. located in non-highly inflationary economies are measured using the currency of the primary economic environment in which they operate as the functional currency, which typically is the local currency. Transaction gains and losses resulting from translating assets and liabilities of these entities into the functional currency are included in other income, net or in equity in earnings of affiliates. When translating into U.S. dollars, income and expense items are translated at average monthly rates of exchange, while assets and liabilities are translated at the rates of exchange at the balance sheet date. Translation adjustments resulting from translating the functional currency into U.S. dollars are deferred and included as a component of AOCI in stockholders’ equity. For operations whose functional currency is the U.S. dollar, nonmonetary assets are translated into U.S. dollars at historical exchange rates and monetary assets are translated at current exchange rates. Because the economy in Venezuela was considered highly inflationary under GAAP, we remeasured the financial statements of our subsidiaries in Venezuela through the January 2015 date of divestiture as if their functional currency was the U.S. dollar. Prior to 2014, the Venezuelan government through its Commission for the Administration of Foreign Exchange (CADIVI) maintained a fixed official exchange rate. In March 2013, the Venezuelan government announced the creation of the Complementary System of Foreign Currency Administration (SICAD), a supplementary currency auction system regulated by the Central Bank of Venezuela for purchases of U.S. dollars by certain eligible importers. During 2013, our subsidiaries in Venezuela were not eligible to utilize SICAD and therefore we continued to use the official exchange rate to remeasure the financial statements of our subsidiaries in Venezuela. In the first quarter of 2014, the Venezuelan government transferred the administration of the official exchange rate to the National Center of Foreign Commerce (CENCOEX) and indicated that the official exchange rate would be increasingly reserved only for the settlement of U.S. dollar-denominated obligations related to purchases of “essential goods and services.” In addition, the Venezuelan government expanded the entities and transactions that would be eligible to use SICAD. Transactions eligible for SICAD included foreign investments and payments of royalties. Also during the first quarter of 2014, the Venezuelan government announced the creation of SICAD 2, a market-based exchange mechanism regulated by the Central Bank of Venezuela. SICAD 2 could be used by all companies incorporated or domiciled in Venezuela who want to obtain U.S. dollars for any purpose. With the expansion of SICAD and the formation of SICAD 2 there was uncertainty surrounding transactions that CENCOEX would allow to be transacted at the official exchange rate. In consultation with legal counsel we determined that the SICAD rate, which we believed would apply to dividend remittances, was the appropriate rate to remeasure the bolivar- denominated net monetary assets of our subsidiaries in Venezuela. Effective March 31, 2014, we ceased using the official exchange rate and began using the SICAD rate to remeasure the financial statements of our subsidiaries in Venezuela. See Note 17 for additional information. In January 2015, we completed the divestiture of our operations in Venezuela. See Note 2 for additional information. Income taxes — In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax assets or liabilities for all years subject to examination based upon management’s evaluation of the facts and circumstances and information available at the reporting dates. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, the related interest cost has also been recognized as a component of the income tax provision. Research and development — Research and development costs include expenditures for research activities relating to product development and improvement. Salaries, fringes and occupancy costs, including building, utility and overhead costs, comprise the vast majority of these expenses and are expensed as incurred. Research and development expenses were $75, $72 and $64 in 2015, 2014 and 2013. Recently adopted accounting pronouncements In August 2015, the Financial Accounting Standards Board (FASB) issued guidance that resolves the issue of whether the scope exception in existing derivatives and hedging guidance is applicable to certain electricity contracts, permitting application of the exception. The guidance confirmed that a forward contract to purchase or sell electricity that is transmitted through a grid operated by an independent system operator will meet the physical delivery criterion under the normal purchases and normal sales scope exception. This guidance is effective immediately, permitting entities to designate prospective qualifying contracts as normal purchases or normal sales. Adoption of the guidance did not impact our consolidated financial statements. In April 2015, the FASB issued guidance which changes the presentation of debt issuance costs. Debt issuance costs related to term debt will be presented on the balance sheet as a direct deduction from the related debt liability rather than recorded as a separate asset. The amendment does not affect the recognition and measurement of debt issuance costs. There is no effect on the statement of operations as debt issuance costs will continue to be amortized to interest expense. Subsequently, the SEC staff announced that it will not object when debt issuance costs related to a revolving debt arrangement are presented as an asset regardless of whether or not there is an outstanding balance on the revolving debt arrangement. The guidance becomes effective January 1, 2016 and requires retrospective application to all prior periods presented. We adopted the guidance effective December 31, 2015. We have presented $21 and $25 of debt issuance costs as a direct deduction from long-term debt as of December 31, 2015 and 2014. We continue to present debt issuance costs associated with revolving debt arrangements in other noncurrent assets. In April 2014, the FASB issued guidance that revises the definition of a discontinued operation. The revised definition limits discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on operations and financial results. The guidance also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance applies to covered transactions that occur after December 31, 2014. The significance of this guidance for us is dependent on any qualifying future dispositions or disposals. Recently issued accounting pronouncements In November 2015, the FASB issued guidance that simplifies the balance sheet classification of deferred taxes. Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. This amendment simplifies the presentation to require that all deferred tax liabilities and assets be classified as noncurrent on the balance sheet. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction. The change to noncurrent classification will have an impact on working capital. This guidance becomes effective January 1, 2017 and allows for prospective or retrospective application, with appropriate disclosures. Early adoption is permitted. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In September 2015, the FASB issued an amendment that eliminates the requirement to restate prior period financial statements for measurement period adjustments in accounting for business combinations. Entities should recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This guidance becomes effective January 1, 2016 and requires prospective application. The guidance will apply to any qualifying future business combinations. In July 2015, the FASB issued an amendment that changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. This amendment only addresses the measurement of inventory if its value declines or is impaired. The guidance on determining the cost of inventory is not being amended. This guidance becomes effective January 1, 2017 and requires prospective application. Early adoption is permitted. Adoption of this guidance will have no impact on our consolidated financial statements. In May 2015, the FASB issued guidance that modifies disclosures related to investments for which fair value is measured using the net asset value (or its equivalent) per share practical expedient by eliminating the requirement to categorize such assets under the fair value hierarchy. The new guidance also eliminates the requirement to include in certain disclosures those investments that are merely eligible to be measured using the practical expedient, limiting the disclosures to those investments actually valued under that approach. This guidance becomes effective January 1, 2016 and requires retrospective application. The adoption of this guidance will have no impact on our consolidated financial statements but could impact pension asset disclosures. In April 2015, the FASB issued an amendment to provide explicit guidance about a customer's accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, then the customer should account for the arrangement as a service contract. The guidance is effective January 1, 2016 and can be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. We will be adopting the amendment prospectively and do not expect the guidance to have an impact on our consolidated financial statements. In April 2015, the FASB issued guidance to provide for a practical expedient that permits an entity to measure defined benefit plan assets and obligations as of the month end that is closest to the entity's fiscal year end or the month end that is closest to the date of a significant event caused by the entity that occurred in an interim period. Significant events, such as a plan amendment, settlement or curtailment, call for a remeasurement in accordance with existing requirements. An entity is required to disclose the accounting policy election and the date used to measure defined benefit plan assets and obligations. The guidance is effective January 1, 2016. The guidance will not impact our consolidated financial statements. In February 2015, the FASB released updated consolidation guidance that entities must use to evaluate specific ownership and contractual arrangements that lead to a consolidation conclusion. The updates could change consolidation outcomes affecting presentation and disclosures. This guidance, which is effective January 1, 2016, is not expected to impact our consolidated financial statements. In June 2014, the FASB issued guidance to provide clarity on whether to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting or as a nonvesting condition that affects the grant-date fair value of a share-based payment award. Generally, an award with a performance target also requires an employee to render service until the performance target is achieved. In some cases, however, the terms of an award may provide that the performance target could be achieved after an employee completes the requisite service period. The amendment requires that a performance target that affects vesting and extends beyond the end of the service period be treated as a performance condition and not as a factor in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The guidance, which is effective January 1, 2016, is not expected to impact our consolidated financial statements. In May 2014, the FASB issued guidance that requires companies to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in amounts that reflect the consideration a company expects to be entitled to in exchange for those goods or services. The new guidance will also require new disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, the FASB adopted a one-year deferral of this guidance. As a result, this guidance will be effective January 1, 2018 with the option to adopt the standard as of the original January 1, 2017 effective date. The guidance allows for either a full retrospective or a modified retrospective transition method. We are currently evaluating the impact this guidance will have on our consolidated financial statements including changes to internal processes and controls.

Summary of significant accounting policies

Basis of presentation — Our consolidated financial statements include the accounts of all subsidiaries where we hold a controlling financial interest. The ownership interests in subsidiaries held by third parties are presented in the consolidated balance sheet within equity, but separate from the parent’s equity, as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in 20 to 50%-owned affiliates, which are not required to be consolidated, are generally accounted for under the equity method. Equity in earnings of these investments is presented separately in the consolidated statement of operations, net of tax. Investments in less-than-20%-owned companies are generally included in the financial statements at the cost of our investment. Dividends, royalties and fees from these cost basis affiliates are recorded in income when received.

In the first quarter of 2015, we identified an error attributable to the calculation of noncontrolling interests net income of a subsidiary. The error resulted in an understatement of noncontrolling equity and noncontrolling interests net income and a corresponding overstatement of parent company stockholders' equity and net income attributable to the parent company in prior periods. Based on our assessments of qualitative and quantitative factors, the error and related impacts were not considered material to the financial statements of the prior periods to which they relate. The error was corrected in March 2015 by increasing noncontrolling interests net income by $9. The correction was not considered material to our 2015 net income attributable to the parent company.

In the third quarter of 2014, we identified an error that had resulted in a $10 overstatement of the values assigned to our defined benefit pension obligation and goodwill when we applied fresh start accounting in 2008. These overstatements affected pension expense, other comprehensive income and impairment of goodwill in subsequent periods. Based on our assessments of qualitative and quantitative factors, the error and the related impacts were not considered material to the financial statements for the quarter ended September 30, 2014 or the prior periods to which they relate. The error was corrected in September 2014 by decreasing pension and postretirement obligations by $17, decreasing accumulated other comprehensive loss by $3 to eliminate the related impacts on unrecognized pension expense and currency translation adjustments, decreasing goodwill by $3, decreasing cost of sales by $5 to reverse the cumulative impact on pension expense and crediting other income, net for $6 to effectively reverse a portion of the goodwill impairment recognized in 2008.

Held for sale — We classify long-lived assets or disposal groups as held for sale in the period: management commits to a plan to sell; the long-lived asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such long-lived assets or disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell have been initiated; the sale is probable within one year; the asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Long-lived assets and disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. See Note 2 for additional information regarding the disposal group held for sale at the end of 2014 and divested in January 2015.

Discontinued operations — Prior to January 1, 2015, we would classify a business component that had been disposed of or classified as held for sale as discontinued operations if the cash flows of the component were eliminated from our ongoing operations and we no longer had any significant continuing involvement in or with the component. The results of operations of our discontinued operations, including any gains or losses on disposition, were aggregated and presented on one line in the income statement. See Recently adopted accounting pronouncements in this note for a description of the current practice and Note 2 for additional information regarding our discontinued operations.

Estimates — Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP), which require the use of estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. We believe our assumptions and estimates are reasonable and appropriate. However, due to the inherent uncertainties in making estimates, actual results could differ from those estimates.

Fair value measurements — A three-tier fair value hierarchy is used to prioritize the inputs to valuation techniques used to measure fair value. The three levels of inputs are as follows: Level 1 inputs (highest priority) include unadjusted quoted prices in active markets for identical instruments. Level 2 inputs include quoted prices for similar instruments that are observable either directly or indirectly. Level 3 inputs (lowest priority) include unobservable inputs in which there is little or no market data, which require management to develop its own assumptions. Classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The inputs we use in our valuation techniques include market data or assumptions that we believe market participants would use in pricing an asset or liability, including assumptions about risk when appropriate. Our valuation techniques include a combination of observable and unobservable inputs. When available, we use quoted market prices to determine the fair value (market approach). In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, we consider the amount and timing of estimated future cash flows and assumed discount rates reflecting varying degrees of credit risk that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date (income approach). Fair values may not represent actual values of the financial instruments that could be realized as of the balance sheet date or that will be realized in the future.

Cash and cash equivalents — Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have maturities of three months or less when purchased.

Marketable securities — Our investments in marketable securities reported in the accompanying balance sheet are classified as available for sale and carried at fair value. Unrealized gains and losses are recorded in accumulated other comprehensive income (loss) (AOCI) until realized. Realized gains and losses are recorded using the specific identification method.

Inventories — Inventories are valued at the lower of cost or market. Cost is determined using the average or first-in, first-out (FIFO) cost method.

Property, plant and equipment — As a result of our adoption of fresh start accounting on February 1, 2008, property, plant and equipment was stated at fair value with useful lives ranging from two to thirty years. Useful lives of newly acquired assets are generally twenty to thirty years for buildings and building improvements, five to ten years for machinery and equipment, three to five years for tooling and office equipment and three to ten years for furniture and fixtures. Depreciation is recognized over the estimated useful lives using primarily the straight-line method for financial reporting purposes and accelerated depreciation methods for federal income tax purposes. If assets are impaired, their value is reduced via an increase in accumulated depreciation.

Pre-production costs related to long-term supply arrangements — The costs of tooling used to make products sold under long-term supply arrangements are capitalized as part of property, plant and equipment and amortized over their useful lives if we own the tooling or if we fund the purchase but our customer owns the tooling and grants us the irrevocable right to use the tooling over the contract period. If we have a contractual right to bill our customers, costs incurred in connection with the design and development of tooling are carried as a component of other accounts receivable until invoiced. Design and development costs related to customer products are deferred if we have an agreement to collect such costs from the customer; otherwise, they are expensed when incurred. At December 31, 2015, the machinery and equipment component of property, plant and equipment includes $3 of our tooling related to long-term supply arrangements, while trade and other accounts receivable includes $27 of costs related to tooling that we have a contractual right to collect from our customers.

Goodwill — We test goodwill for impairment annually as of October 31 and more frequently if events occur or circumstances change that would warrant an interim review. Goodwill impairment testing is performed at the reporting unit level, which is our operating segment. We estimate the fair value of the reporting unit in the first step using various valuation methodologies, including projected future cash flows and multiples of current earnings. If the estimated fair value of the reporting unit exceeds its carrying value, the goodwill is considered not impaired. If the carrying value of the reporting unit exceeds its estimated fair value, then the second step of the test would be required to determine the implied fair value of the goodwill and any resulting impairment. Our goodwill is assigned to our Off-Highway segment. The estimated fair value of our Off-Highway reporting unit was significantly greater than its carrying value at October 31, 2015. No impairment of goodwill occurred during the three years ended December 31, 2015.

Intangible assets — Intangible assets include the value of core technology, trademarks and trade names, customer relationships and intangible assets used in research and development activities. Core technology and customer relationships have definite lives while intangible assets used in research and development activities and substantially all of our trademarks and trade names have indefinite lives. Definite-lived intangible assets are amortized over their useful life using the straight-line method of amortization and are periodically reviewed for impairment indicators. Amortization of core technology is charged to cost of sales. Amortization of trademarks and trade names and customer relationships is charged to amortization of intangibles. Intangible assets used in research and development activities have an indefinite life until completion of the associated research and development efforts. Upon completion of development, the assets are amortized over their useful life; if the project is abandoned, the assets are written off immediately. Indefinite-lived intangible assets are tested for impairment annually and more frequently if impairment indicators exist. See Notes 2 and 3 for more information about intangible assets.

Investments in affiliates — Investments in affiliates include investments accounted for under the equity and cost methods. We monitor our investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis in accordance with GAAP. Indicators include, but are not limited to, current economic and market conditions, operating performance of the affiliate, including current earnings trends and undiscounted cash flows, and other affiliate-specific information. If we determine that an other-than-temporary decline in value has occurred, we recognize an impairment loss, which is measured as the excess of the investment's recorded carrying value over its fair value. The fair value determination, particularly for investments in privately-held companies, requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and determination of whether any identified impairment is other than temporary. See Note 19 for further information about our investment in affiliates.

Tangible asset impairments — We review the carrying value of amortizable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the undiscounted future net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of are reported at the lower of their carrying amount or fair value less costs to sell and are no longer depreciated.

Other long-lived assets and liabilities — We discount our workers’ compensation and asbestos liabilities and the related amounts recoverable from insurers by applying blended risk-free rates that are appropriate for the duration of the projected cash flows. The use of risk-free rates is considered appropriate given that other risks affecting the volume and timing of payments have been considered in developing the probability-weighted projected cash flows. The blended risk-free rates are revised annually to consider incremental cash flow projections.

Financial instruments — The carrying values of cash and cash equivalents, trade receivables and short-term borrowings approximate fair value. Notes receivable are carried at fair value, which considers the contractual call or selling price, if applicable. Borrowings under our credit facilities are carried at historical cost and adjusted for principal payments and foreign currency fluctuations.

Derivatives — Foreign currency forward contracts and currency swaps are carried at fair value. We enter into these contracts to manage our exposure to the impact of currency fluctuations on certain foreign currency-denominated assets and liabilities and on a portion of our forecasted purchase and sale transactions. On occasion, we also enter into net investment hedges to protect the translated U.S. dollar value of our investment in certain foreign subsidiaries.

Changes in the fair value of currency-related contracts treated as cash flow hedges are deferred and included as a component of other comprehensive income (loss) (OCI) to the extent the contracts remain effective and the associated forecasted transactions remain probable. Effectiveness is measured by using regression analysis to determine the degree of correlation between the change in the fair value of the derivative instrument and the change in the associated foreign currency exchange rates. Deferred gains and losses are reclassified to other income, net in the same periods in which the underlying transactions affect earnings.

Changes in the fair value of contracts not treated as cash flow hedges or as net investment hedges are recognized in other income, net in the period in which those changes occur. Changes in the fair value of contracts treated as net investment hedges are recorded in the cumulative translation adjustment (CTA) component of OCI. Amounts recorded in CTA are deferred until such time as the investment in the associated subsidiary is substantially liquidated.

We may also use interest rate swaps to manage exposure to fluctuations in interest rates and to adjust the mix of our fixed-rate and variable-rate debt. With our current portfolio of fixed-rate debt, we occasionally execute a fixed-to-floating interest rate swap which serves to convert our fixed-rate debt to variable-rate debt. As a fair value hedge of the underlying debt, changes in the fair values of the swap and the underlying debt are recorded in interest expense. We do not use derivatives for trading or speculative purposes and we do not hedge all of our exposures.

Environmental compliance and remediation — Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to existing conditions caused by past operations that do not contribute to our current or future revenue generation are expensed. Liabilities are recorded when environmental assessments and/or remedial efforts are probable and the costs can be reasonably estimated. We consider the most probable method of remediation, current laws and regulations and existing technology in determining our environmental liabilities.

Pension and other postretirement defined benefits — Net pension and postretirement benefits expenses and the related liabilities are determined on an actuarial basis. These plan expenses and obligations are dependent on management’s assumptions developed in consultation with our actuaries. We review these actuarial assumptions at least annually and make modifications when appropriate. With the input of independent actuaries and other relevant sources, we believe that the assumptions used are reasonable; however, changes in these assumptions, or experience different from that assumed, could impact our financial position, results of operations or cash flows.

Postemployment benefits — Costs to provide postemployment benefits to employees are accounted for on an accrual basis. Obligations that do not accumulate or vest are recorded when payment is probable and the amount can be reasonably estimated. For those obligations that accumulate or vest and the amount can be reasonably estimated, expense and the related liability are recorded as service is rendered.

Equity-based compensation — We measure compensation cost arising from the grant of share-based awards to employees at fair value. We recognize such costs in income over the period during which the requisite service is provided, usually the vesting period. The grant date fair value is estimated using valuation techniques that require the input of management estimates and assumptions. We believe that the assumptions used are reasonable; however, due to inherent uncertainties in making estimates, if other assumptions had been used, it could have impacted our financial position and results of operations.

Revenue recognition — Sales are recognized when products are shipped and risk of loss has transferred to the customer. We accrue for warranty costs, sales returns and other allowances based on experience and other relevant factors when sales are recognized. Adjustments are made as new information becomes available. Shipping and handling fees billed to customers are included in sales, while costs of shipping and handling are included in cost of sales. Taxes collected from customers are excluded from revenues and credited directly to obligations to the appropriate governmental agencies.

Foreign currency translation — The financial statements of subsidiaries and equity affiliates outside the U.S. located in non-highly inflationary economies are measured using the currency of the primary economic environment in which they operate as the functional currency, which typically is the local currency. Transaction gains and losses resulting from translating assets and liabilities of these entities into the functional currency are included in other income, net or in equity in earnings of affiliates. When translating into U.S. dollars, income and expense items are translated at average monthly rates of exchange, while assets and liabilities are translated at the rates of exchange at the balance sheet date. Translation adjustments resulting from translating the functional currency into U.S. dollars are deferred and included as a component of AOCI in stockholders’ equity. For operations whose functional currency is the U.S. dollar, nonmonetary assets are translated into U.S. dollars at historical exchange rates and monetary assets are translated at current exchange rates.

Because the economy in Venezuela was considered highly inflationary under GAAP, we remeasured the financial statements of our subsidiaries in Venezuela through the January 2015 date of divestiture as if their functional currency was the U.S. dollar.

Prior to 2014, the Venezuelan government through its Commission for the Administration of Foreign Exchange (CADIVI) maintained a fixed official exchange rate. In March 2013, the Venezuelan government announced the creation of the Complementary System of Foreign Currency Administration (SICAD), a supplementary currency auction system regulated by the Central Bank of Venezuela for purchases of U.S. dollars by certain eligible importers. During 2013, our subsidiaries in Venezuela were not eligible to utilize SICAD and therefore we continued to use the official exchange rate to remeasure the financial statements of our subsidiaries in Venezuela.

In the first quarter of 2014, the Venezuelan government transferred the administration of the official exchange rate to the National Center of Foreign Commerce (CENCOEX) and indicated that the official exchange rate would be increasingly reserved only for the settlement of U.S. dollar-denominated obligations related to purchases of “essential goods and services.” In addition, the Venezuelan government expanded the entities and transactions that would be eligible to use SICAD. Transactions eligible for SICAD included foreign investments and payments of royalties. Also during the first quarter of 2014, the Venezuelan government announced the creation of SICAD 2, a market-based exchange mechanism regulated by the Central Bank of Venezuela. SICAD 2 could be used by all companies incorporated or domiciled in Venezuela who want to obtain U.S. dollars for any purpose.

With the expansion of SICAD and the formation of SICAD 2 there was uncertainty surrounding transactions that CENCOEX would allow to be transacted at the official exchange rate. In consultation with legal counsel we determined that the SICAD rate, which we believed would apply to dividend remittances, was the appropriate rate to remeasure the bolivar- denominated net monetary assets of our subsidiaries in Venezuela. Effective March 31, 2014, we ceased using the official exchange rate and began using the SICAD rate to remeasure the financial statements of our subsidiaries in Venezuela. See Note 17 for additional information. In January 2015, we completed the divestiture of our operations in Venezuela. See Note 2 for additional information.

Income taxes — In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax assets or liabilities for all years subject to examination based upon management’s evaluation of the facts and circumstances and information available at the reporting dates. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, the related interest cost has also been recognized as a component of the income tax provision.

Research and development — Research and development costs include expenditures for research activities relating to product development and improvement. Salaries, fringes and occupancy costs, including building, utility and overhead costs, comprise the vast majority of these expenses and are expensed as incurred. Research and development expenses were $75, $72 and $64 in 2015, 2014 and 2013.

Recently adopted accounting pronouncements

In August 2015, the Financial Accounting Standards Board (FASB) issued guidance that resolves the issue of whether the scope exception in existing derivatives and hedging guidance is applicable to certain electricity contracts, permitting application of the exception. The guidance confirmed that a forward contract to purchase or sell electricity that is transmitted through a grid operated by an independent system operator will meet the physical delivery criterion under the normal purchases and normal sales scope exception. This guidance is effective immediately, permitting entities to designate prospective qualifying contracts as normal purchases or normal sales. Adoption of the guidance did not impact our consolidated financial statements.

In April 2015, the FASB issued guidance which changes the presentation of debt issuance costs. Debt issuance costs related to term debt will be presented on the balance sheet as a direct deduction from the related debt liability rather than recorded as a separate asset. The amendment does not affect the recognition and measurement of debt issuance costs. There is no effect on the statement of operations as debt issuance costs will continue to be amortized to interest expense. Subsequently, the SEC staff announced that it will not object when debt issuance costs related to a revolving debt arrangement are presented as an asset regardless of whether or not there is an outstanding balance on the revolving debt arrangement. The guidance becomes effective January 1, 2016 and requires retrospective application to all prior periods presented. We adopted the guidance effective December 31, 2015. We have presented $21 and $25 of debt issuance costs as a direct deduction from long-term debt as of December 31, 2015 and 2014. We continue to present debt issuance costs associated with revolving debt arrangements in other noncurrent assets.

In April 2014, the FASB issued guidance that revises the definition of a discontinued operation. The revised definition limits discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on operations and financial results. The guidance also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance applies to covered transactions that occur after December 31, 2014. The significance of this guidance for us is dependent on any qualifying future dispositions or disposals.

Recently issued accounting pronouncements

In November 2015, the FASB issued guidance that simplifies the balance sheet classification of deferred taxes. Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. This amendment simplifies the presentation to require that all deferred tax liabilities and assets be classified as noncurrent on the balance sheet. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction. The change to noncurrent classification will have an impact on working capital. This guidance becomes effective January 1, 2017 and allows for prospective or retrospective application, with appropriate disclosures. Early adoption is permitted. We are currently evaluating the impact this guidance will have on our consolidated financial statements.

In September 2015, the FASB issued an amendment that eliminates the requirement to restate prior period financial statements for measurement period adjustments in accounting for business combinations. Entities should recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This guidance becomes effective January 1, 2016 and requires prospective application. The guidance will apply to any qualifying future business combinations.

In July 2015, the FASB issued an amendment that changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. This amendment only addresses the measurement of inventory if its value declines or is impaired. The guidance on determining the cost of inventory is not being amended. This guidance becomes effective January 1, 2017 and requires prospective application. Early adoption is permitted. Adoption of this guidance will have no impact on our consolidated financial statements.

In May 2015, the FASB issued guidance that modifies disclosures related to investments for which fair value is measured using the net asset value (or its equivalent) per share practical expedient by eliminating the requirement to categorize such assets under the fair value hierarchy. The new guidance also eliminates the requirement to include in certain disclosures those investments that are merely eligible to be measured using the practical expedient, limiting the disclosures to those investments actually valued under that approach. This guidance becomes effective January 1, 2016 and requires retrospective application. The adoption of this guidance will have no impact on our consolidated financial statements but could impact pension asset disclosures.

In April 2015, the FASB issued an amendment to provide explicit guidance about a customer's accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, then the customer should account for the arrangement as a service contract. The guidance is effective January 1, 2016 and can be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. We will be adopting the amendment prospectively and do not expect the guidance to have an impact on our consolidated financial statements.

In April 2015, the FASB issued guidance to provide for a practical expedient that permits an entity to measure defined benefit plan assets and obligations as of the month end that is closest to the entity's fiscal year end or the month end that is closest to the date of a significant event caused by the entity that occurred in an interim period. Significant events, such as a plan amendment, settlement or curtailment, call for a remeasurement in accordance with existing requirements. An entity is required to disclose the accounting policy election and the date used to measure defined benefit plan assets and obligations. The guidance is effective January 1, 2016. The guidance will not impact our consolidated financial statements.

In February 2015, the FASB released updated consolidation guidance that entities must use to evaluate specific ownership and contractual arrangements that lead to a consolidation conclusion. The updates could change consolidation outcomes affecting presentation and disclosures. This guidance, which is effective January 1, 2016, is not expected to impact our consolidated financial statements.

In June 2014, the FASB issued guidance to provide clarity on whether to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting or as a nonvesting condition that affects the grant-date fair value of a share-based payment award. Generally, an award with a performance target also requires an employee to render service until the performance target is achieved. In some cases, however, the terms of an award may provide that the performance target could be achieved after an employee completes the requisite service period. The amendment requires that a performance target that affects vesting and extends beyond the end of the service period be treated as a performance condition and not as a factor in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The guidance, which is effective January 1, 2016, is not expected to impact our consolidated financial statements.

In May 2014, the FASB issued guidance that requires companies to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in amounts that reflect the consideration a company expects to be entitled to in exchange for those goods or services. The new guidance will also require new disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, the FASB adopted a one-year deferral of this guidance. As a result, this guidance will be effective January 1, 2018 with the option to adopt the standard as of the original January 1, 2017 effective date. The guidance allows for either a full retrospective or a modified retrospective transition method. We are currently evaluating the impact this guidance will have on our consolidated financial statements including changes to internal processes and controls.
