Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies	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 are prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. These statements are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results for the interim periods. The results reported in these consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the consolidated financial statements in Item 8 of our 2014 Form 10-K. 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 is not anticipated to be material to our 2015 full year net income attributable to the parent company. Historically, we have not adjusted the purchases of property, plant and equipment presented in our consolidated statement of cash flows for invoices not paid in cash as of the end of the period. While the error had no impact on the total net cash flows presented in any prior period it did result in a misclassification between net cash provided by (used in) operating activities and net cash used in investing activities. Prior period amounts have been revised to properly reflect capital invoices not paid in cash as of the end of each period presented. Purchases of property, plant and equipment previously presented for the six months ended June 30, 2014, have been increased by $30 with a corresponding offset to change in working capital. At June 30, 2015 and 2014, we had $46 and $13 of purchases of property, plant and equipment included in accounts payable. 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 Note 2 for additional information regarding our discontinued operations. Recently adopted accounting pronouncements In April 2014, the Financial Accounting Standards Board (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 Dana is dependent on any qualifying future dispositions or disposals. Recently issued accounting pronouncements In May 2015, the FASB issued guidance that removes from the fair value hierarchy investments for which fair value is measured at net asset value (or its equivalent) using the available practical expedient. The new guidance also modifies the scope of the disclosures related to such investments, eliminating from scope those investments eligible for but not actually valued using the practical expedient. Entities must continue to disclose information on investments for which fair value is measured at net asset value (or its equivalent) using the practical expedient, including information that helps readers understand the investments and whether the investments, if sold, are probable of being sold at amounts that differ from the net asset value. This guidance becomes effective January 1, 2016 and requires retrospective application. Early adoption is permitted. We are currently evaluating the impact this guidance will have on disclosures covering certain assets held by our pension plans. 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 are currently evaluating the impact this guidance will have 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 and early adoption is permitted. The guidance will 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. The guidance becomes effective January 1, 2016 and requires retrospective application to all prior periods presented. We intend to early adopt the guidance effective December 31, 2015. 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 becomes effective January 1, 2016. We are currently evaluating the impact this guidance will have on 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 effective date, January 1, 2017. 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.

Summary of significant accounting policies

Basis of presentation — Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. These statements are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results for the interim periods. The results reported in these consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the consolidated financial statements in Item 8 of our 2014 Form 10-K.

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 and early adoption is permitted. The guidance will not impact our consolidated financial statements.

The guidance becomes effective January 1, 2016 and requires retrospective application to all prior periods presented. We intend to early adopt the guidance effective December 31, 2015.

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 becomes effective January 1, 2016. We are currently evaluating the impact this guidance will have on 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.

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 effective date, January 1, 2017. 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.
