Organization and Summary of Significant Accounting Policies

General

Dana Incorporated (Dana) is headquartered in Maumee, Ohio and was incorporated in Delaware in 2007. We are a global provider of high technology drive and motion products, sealing solutions, thermal-management technologies and fluid-power products and our customer base includes virtually every major vehicle and engine 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. 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 fourth quarter of 2017, we identified an error in the classification of a third-party ownership interest in a subsidiary of Brevini Power Transmission S.p.A. Based on put and call provisions provided for in the agreement between the parties, the third-party ownership interest should have been classified as a redeemable noncontrolling interest. This balance sheet error was corrected in December 2017 by increasing redeemable noncontrolling interests and reducing noncontrolling interests by $3. The purchase consideration allocation presented in Note 2 and the initial fair value of redeemable noncontrolling interests of acquired businesses presented in Note 9 include this correction.

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.

Discontinued operations — The results of operations of a component or a group of components that either has been disposed of or is classified as held for sale is reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on operations and financial results.

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. We recorded unrealized gains and losses in accumulated other comprehensive income (loss) (AOCI) through the end of 2017 but recorded them in net income beginning in 2018 to comply with new accounting guidance. Realized gains and losses are recorded using the specific identification method.

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

Property, plant and equipment — Property, plant and equipment are recorded at cost. 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. 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. 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, 2018, the machinery and equipment component of property, plant and equipment includes $31 of our tooling related to long-term supply arrangements. The increase during 2018 reflects the start of production for our recently awarded customer contracts. Also at December 31, 2018, trade and other accounts receivable includes $53 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 the operating segment in the case of our Off-Highway and Commercial Vehicle goodwill. 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. The estimated fair value of our reporting units were greater than their carrying values at October 31, 2018. No impairment of goodwill occurred during the three years ended December 31, 2018.

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 Note 4 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 22 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 obligations 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. We also periodically enter into fixed-to-fixed cross-currency swaps on foreign currency-denominated external or intercompany debt instruments to reduce our exposure to foreign currency exchange rate risk. Such fixed-to-fixed cross-currency swaps are designated as cash flow hedges. We do not use derivatives for trading or speculative purposes and we do not hedge all of our exposures.

For derivative instruments designated as cash flow hedges, at the cash flow hedge’s inception and on an ongoing basis, the company formally assesses whether the cash flow hedging instruments have been highly effective in offsetting changes in the cash flows of the hedged transactions and whether those cash flow hedging instruments may be expected to remain highly effective in future periods. 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). For our fixed-to-fixed cross-currency swaps, a review of critical terms is performed each period to establish that an assumption of effectiveness remains appropriate. Deferred gains and losses are reclassified to earnings 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 (expense), 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 fixed-to-floating or floating-to-fixed interest rate swaps to manage exposure to fluctuations in interest rates and to adjust the mix of our fixed-rate and 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. No such fixed-to-floating or floating-to-fixed swaps were outstanding at December 31, 2018. See Note 15 for additional information.

Cash flows associated with designated derivatives are classified within the same category as the item being hedged on the consolidated statement of cash flows. Cash flows associated with undesignated derivatives are included in the investing category on the consolidated statement of cash flows.

Warranty — Costs related to product warranty obligations are estimated and accrued at the time of sale with a charge against cost of sales. Warranty accruals are evaluated and adjusted as appropriate based on occurrences giving rise to potential warranty exposure and associated experience. Warranty accruals and adjustments require significant judgment, including a determination of our involvement in the matter giving rise to the potential warranty issue or claim, our contractual requirements, estimates of units requiring repair and estimates of repair costs.

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.

Revenue recognition — Sales are recognized when products are shipped and risk of loss has transferred to the customer. See Recently adopted accounting pronouncements in this note for a description of the current practice and Note 20 for additional information regarding the related impact on our segment reporting. 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 (expense), 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.

We believe that Argentina's economy met the GAAP definition of a highly inflationary economy during the second quarter of 2018. As such, effective July 1, 2018 we began to remeasure the financial statements of our Argentine subsidiaries as if their functional currency was the U.S. dollar. In assessing Argentina's economy as highly inflationary we considered its three-year cumulative inflation rate along with other factors. We believe the National Wholesale Price Index (WPI) provides the most reliable calculation of cumulative inflation for Argentina as the WPI has consistently provided national coverage and historically has been viewed as the most relevant and reliable measure by practitioners. Argentina's three-year cumulative inflation rate through May 2018 based on the WPI was 109%. In addition, management considered the Central Bank of Argentina increasing annual interest rates to 30% in April 2018 and further increasing them to 40% in May 2018, the Argentine government requesting financial assistance from the International Monetary Fund and the significant depreciation of the Argentine peso against the U.S. dollar during the second quarter of 2018.

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 $103, $102 and $81 in 2018, 2017 and 2016.

Recently adopted accounting pronouncements

On January 1, 2018, we adopted Accounting Standard Update (ASU) 2017-12, Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities, guidance that addresses effectiveness testing requirements, income statement presentation and disclosure and hedge accounting qualification criteria. Adoption of this standard results in a prospective change to the presentation of certain hedging-related gains and losses in our consolidated statement of operations. Effective with our permitted early adoption of this standard on January 1, 2018, realized gains and losses on forecasted transactions are recorded in the financial statement line item to which the underlying forecasted transaction relates (e.g., sales or cost of sales). Adoption also simplifies our ongoing effectiveness testing and reduces the complexity of hedge accounting requirements for new hedging contracts. The adoption of this standard, including the change in presentation within the consolidated statement of operations, did not have a material impact.

On January 1, 2018, we adopted ASU 2017-07, Retirement Benefits – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, guidance that changed the reporting of pension and other postretirement benefits (OPEB) costs in the income statement. The service cost components of net periodic pension and OPEB costs continue to be included in cost of sales and selling, general and administrative expenses as part of compensation cost and remain eligible for capitalization in inventory and other assets. The non-service components are now reported in other income (expense), net and are not eligible for capitalization. The impact of the new guidance on inventory at December 31, 2018 was not material. For 2017, we reclassified net pension and OPEB costs of $4 from cost of sales and $3 from selling, general and administrative expenses to other income (expense), net to conform to the 2018 presentation. For 2016, we reclassified net pension and OPEB income of $9 from cost of sales and net pension and OPEB costs of $5 from selling, general and administrative expenses to other income (expense), net. We used the practical expedient in the guidance to quantify these impacts, which disregards the potential change in capitalized costs during the period. See Note 20 for information regarding the related impact on our segment reporting.

On January 1, 2018, we adopted ASU 2016-18, Statement of Cash Flows – Restricted Cash, guidance that requires the statement of cash flows to explain the change during the period in the total cash, cash equivalents and amounts generally described as restricted cash. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning and ending total amounts shown on the statement of cash flows. Retrospective presentation is required. For 2016 and 2017, this change resulted in a $9 and $9 increase in cash, cash equivalents and restricted cash at the beginning of the period and a $7 increase at the end of 2017 as presented on our consolidated statement of cash flow. In addition, removing the change in restricted cash from the consolidated statement of cash flows resulted in a change of $2 in our net cash used in investing activities for 2017. See Note 7 for additional information.

On January 1, 2018, we adopted ASU 2016-01, Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities, an amendment that addresses the recognition, measurement, presentation and disclosure of certain financial instruments. Investments in equity securities that were classified as available-for-sale and carried at fair value, with changes in fair value reported in OCI, are now carried at fair value determined on an exit price notion and changes in fair value are now reported in net income. The new guidance also affects the assessment of deferred tax assets related to available-for-sale securities, the accounting for liabilities for which the fair value option is elected and the disclosures of financial assets and financial liabilities in the notes to the financial statements. The adoption resulted in a release of the deferred gain in AOCI directly to retained earnings of $2.

Effective January 1, 2018, we adopted ASU 2014-09, Revenue – Revenue from Contracts with Customers, which 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. We have elected to use the modified retrospective approach to transition to the new standard. Comparative prior periods have not been restated. We assessed our products in combination with the provisions of our current customer contracts to determine the cumulative effect of initially applying ASU 2014-09. Based on our assessment, the adoption date financial statement impact was limited to balance sheet reclassifications required to establish the refund asset, refund liability and contract liability concepts provided for in ASU 2014-09. There was no cumulative effect adjustment required to be recorded to retained earnings. The cumulative effects of the changes made to our January 1, 2018 consolidated balance sheet for the adoption of ASU 2014-09 were as follows:



	Balance at December 31, 2017		Adjustments Due to ASU 2014-09		Balance at January 1, 2018
Assets
Current assets
Accounts receivable - Trade	$	994	$	15	$	1,009
Other current assets	97		1		98

Liabilities
Current liabilities
Other accrued liabilities	$	220	$	16	$	236

The following table shows the impact adopting ASC 606 had on our consolidated balance sheet as of December 31, 2018:



	December 31, 2018
	Balances Without Adoption of ASU 2014-09		Adjustments Due to ASU 2014-09		As Reported
Assets
Current assets
Accounts receivable - Trade	$	1,049	$	16	$	1,065
Other current assets	100		2		102

Liabilities
Current liabilities
Other accrued liabilities	$	251	$	18	$	269

See Note 20 for additional information.

During the third quarter of 2018, we early adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This guidance allows entities the option of reclassifying stranded income tax effects resulting from the Tax Cuts and Jobs Act (the “Act”) from AOCI to retained earnings in their consolidated financial statements. As a result of the Act, deferred taxes were adjusted to reflect the reduction of the historical corporate income tax rate to the newly enacted corporate income tax rate by means of a credit or charge to income from continuing operations, leaving the tax effects of items within AOCI stranded at historical tax rates. This guidance would have been effective January 1, 2019 without early adoption. The guidance is to be applied either in the period of adoption or retrospectively to each period that was affected by the change in the corporate tax rate under the Act. Due to the immaterial amount of the stranded tax effects, we have elected not to reclassify the income tax effects from AOCI to retained earnings.

We also adopted the following standards during 2018, none of which had a material impact on our financial statements or financial statement disclosures:



Standard		Effective Date
2017-09	Stock Compensation – Scope of Modification Accounting	January 1, 2018
2017-01	Business Combinations – Clarifying the Definition of a Business	January 1, 2018
2016-15	Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments	January 1, 2018

Recently issued accounting pronouncements

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance allows for capitalization of implementation costs associated with certain cloud computing arrangements. This guidance becomes effective January 1, 2020 and early adoption is permitted. The guidance is to be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We do not expect the adoption of this guidance to impact our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General, Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. The guidance eliminated certain disclosures about defined benefit plans, added new disclosures, and clarified other requirements. This guidance becomes effective January 1, 2020 and early adoption is permitted. There were no changes to interim disclosure requirements. Adoption of this guidance will not have a material effect on our annual financial statement disclosures.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The guidance removed or modified some disclosures while others were added. The removal and amendment of certain disclosures can be adopted immediately with retrospective application. The additional disclosure guidance becomes effective January 1, 2020. Adoption of this guidance will not have a material effect on our financial statement disclosures.

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share, Distinguishing Liabilities from Equity, Derivatives and Hedging – (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. This guidance is intended to reduce the complexity associated with accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, a down round feature would no longer cause a freestanding equity-linked financial instrument (or an embedded conversion option) to be considered "not indexed to an entity's own stock" and therefore accounted for as a derivative liability at fair value with changes in fair value recognized in current earnings. Down round features are most often found in warrants and conversion options embedded in debt or preferred equity instruments. In addition, the guidance re-characterized the indefinite deferral of certain provisions on distinguishing liabilities from equity to a scope exception with no accounting effect. This guidance becomes effective January 1, 2019 and early adoption is permitted. We do not presently issue any equity-linked financial instruments and therefore this guidance has no impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Goodwill – Simplifying the Test for Goodwill Impairment, guidance that simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 of the goodwill impairment test. The new guidance quantifies goodwill impairment as the amount by which the carrying amount of a reporting unit, including goodwill, exceeds its fair value, with the impairment loss limited to the total amount of goodwill allocated to that reporting unit. This guidance becomes effective January 1, 2020 and will be applied on a prospective basis. Early adoption is permitted for impairment tests performed after January 1, 2017. We do not expect the adoption of this guidance to impact our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Credit Losses – Measurement of Credit Losses on Financial Instruments, new guidance for the accounting for credit losses on certain financial instruments. This guidance introduces a new approach to estimating credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. This guidance, which becomes effective January 1, 2020, is not expected to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, its new lease accounting standard. The primary focus of the standard is on the accounting by lessees. This standard requires lessees to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease) on the balance sheet. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from current GAAP. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern in the income statement. Quantitative and qualitative disclosures are required to provide insight into the extent of revenue and expense recognized and expected to be recognized from leasing arrangements. Approximately three-fourths of our global lease portfolio represents leases of real estate, including manufacturing, assembly and office facilities, while the remainder represents leases of personal property, including manufacturing, material handling and IT equipment.

We expect the adoption of this new standard will result in the recording of leased assets and lease liabilities for our operating leases of approximately $190 as of January 1, 2019. We expect to take advantage of the transition relief provided by the amendment to ASU 2016-02 which allows us to elect not to restate 2017 and 2018 comparative periods upon adoption and continue to apply ASC 840 to such periods. With respect to the available practical expedients, we expect to elect the primary package of expedients whereby we will reassess neither the existence, nor the classification nor the amount and treatment of initial direct costs of existing leases. We do not expect to apply hindsight to the evaluation of lease options (e.g., renewal) and, accordingly, do not expect to utilize the practical expedient that would allow such an approach. Finally, we plan to separate the lease components from the non-lease components of each lease arrangement and, therefore, do not expect to elect the expedient that would enable us not to separate them. This guidance becomes effective January 1, 2019 with early adoption permitted.

Acquisitions

SME — On January 11, 2019, we acquired a 100% ownership interest in the S.M.E. S.p.A. (SME). SME designs, engineers, and manufactures low-voltage AC induction and synchronous reluctance motors, inverters, and controls for a wide range of off-highway electric vehicle applications, including material handling, agriculture, construction, and automated-guided vehicles. The addition of SME's low-voltage motors and inverters, which are primarily designed to meet the evolution of electrification in off-highway equipment, significantly expands Dana's electrified product portfolio.

We paid $88 at closing, consisting of $62 in cash on hand and a note payable of $26 which allows for net settlement of potential contingencies as defined in the purchase agreement. The note is payable in five years and bears annual interest of 5%. Due to the recentness of the transaction, we are currently not able to provide an allocation of the purchase price to the fair value of the assets acquired and liabilities assumed.

TM4 — On June 22, 2018, we acquired a 55% ownership interest in TM4 Inc. (TM4) from Hydro-Québec. TM4 designs and manufactures motors, power inverters, and control systems for electric vehicles, offering a complementary portfolio to Dana's electric gearboxes and thermal-management technologies for batteries, motors, and inverters. The transaction establishes Dana as the only supplier with full e-Drive design, engineering, and manufacturing capabilities – offering electro-mechanical propulsion solutions to each of its end markets. The transaction further strengthens Dana's position in China, the world's fastest-growing market for electric vehicles. TM4 owns a 50% interest in Prestolite E-Propulsion Systems Limited (PEPS), a joint venture in China with Prestolite Electric Beijing Limited, which offers electric mobility solutions throughout China and Asia. The terms of the agreement provide Hydro-Québec with the right to put all, and not less than all, of its shares in TM4 to Dana at fair value any time after June 22, 2021.

We paid $125 at closing, using cash on hand. The purchase consideration and the related allocation to the acquisition date fair values of the assets acquired and liabilities assumed are presented in the following table:



Total purchase consideration	$	125

Cash and cash equivalents	$	3
Accounts receivable - Trade	3
Accounts receivable - Other	1
Inventories	4
Goodwill	148
Intangibles	24
Investment in affiliates	49
Property, plant and equipment	5
Accounts payable	(2		)
Accrued payroll and employee benefits	(1		)
Other accrued liabilities	(7		)
Redeemable noncontrolling interest	(102		)
Total purchase consideration allocation	$	125

Goodwill recognized in this transaction is primarily attributable to synergies expected to arise after the acquisition and the assembled workforce and is not deductible for tax purposes. The provisional fair values assigned to intangibles include $14 allocated to developed technology and $10 allocated to trademarks and trade names. We used the relief from royalty method, an income approach, to value developed technology and the trademarks and trade names. We used a replacement cost method to value fixed assets. We used a combination of the discounted cash flow, an income approach, and the guideline public company method, a market approach, to value the equity method investment in PEPS. The developed technology intangible assets are being amortized on a straight-line basis over ten years, and property, plant and equipment is being depreciated on a straight-line basis over useful lives ranging from five to six years. The trademarks and trade names are considered indefinite-lived intangible assets.

Dana is consolidating TM4 as the governing documents provide Dana with a controlling financial interest. The results of operations of the business are reported in our Commercial Vehicle operating segment from the date of acquisition. Transaction related expenses associated with completion of the acquisition totaling $5 were charged to other income (expense), net. The pro forma effects of this acquisition would not materially impact our reported results for any period presented, and as a result no pro forma financial statements are presented. During 2018, the business contributed sales of $11.

USM – Warren — On March 1, 2017, we acquired certain assets and liabilities relating to the Warren, Michigan production unit of U.S. Manufacturing Corporation (USM). The production unit acquired is in the business of manufacturing axle housings, extruded tubular products and machined components for the automotive industry. The acquisition will increase Dana's revenue from light and commercial vehicle manufacturers and will vertically integrate a significant element of Dana's supply chain. It also provides Dana with new lightweight product and process technologies.

USM contributed certain assets and liabilities relating to its Warren, Michigan production unit to Warren Manufacturing LLC (USM – Warren), a newly created legal entity, and Dana acquired all of the company units of USM – Warren. The company units were acquired by Dana free and clear of any liens. We paid $104 at closing, including $25 to effectively settle trade payable obligations originating from product purchases Dana made from USM prior to the acquisition, and received $1 in the third quarter of 2017 for purchase price adjustments determined under the terms of the agreement. The acquisition has been accounted for as a business combination. The purchase consideration and the related allocation to the acquisition date fair values of the assets acquired and liabilities assumed are presented in the following table:



Total purchase consideration	$	78

Accounts receivable - Trade	$	17
Accounts receivable - Other	3
Inventories	9
Goodwill	3
Intangibles	33
Property, plant and equipment	50
Accounts payable	(34		)
Accrued payroll and employee benefits	(2		)
Other accrued liabilities	(1		)
Total purchase consideration allocation	$	78

Goodwill recognized in this transaction is primarily attributable to synergies expected to arise after the acquisition and the assembled workforce and is deductible for tax purposes. Intangibles includes $30 allocated to customer relationships and $3 allocated to developed technology. We used the relief from royalty method, an income approach, to value developed technology. We used the multi-period excess earnings method, an income approach, to value customer relationships. We used a replacement cost method to value fixed assets. The developed technology and customer relationship intangible assets are being amortized on a straight-line basis over eighteen and eleven years, respectively, and property, plant and equipment is being depreciated on a straight-line basis over useful lives ranging from one to seventeen years.

The results of operations of the business are reported in our Light Vehicle operating segment from the date of acquisition. We incurred transaction related expenses to complete the acquisition in 2017 totaling $5, which were charged to other income (expense), net. The pro forma effects of this acquisition would not materially impact our reported results for any period presented, and as a result no pro forma financial statements are presented. During 2017, the business contributed sales of $96.

BFP and BPT — On February 1, 2017, we acquired 80% ownership interests in Brevini Fluid Power S.p.A. (BFP) and Brevini Power Transmission S.p.A. (BPT) from Brevini Group S.p.A. (Brevini). The acquisition expands our Off-Highway operating segment product portfolio to include technologies for tracked vehicles, doubling our addressable market for off-highway driveline systems and establishing Dana as the only off-highway solutions provider that can manage the power to both move the equipment and perform its critical work functions. This acquisition also brings a platform of technologies that can be leveraged in our light and commercial-vehicle end markets, helping to accelerate our hybridization and electrification initiatives.

We paid $181 at closing, using cash on hand, and refinanced a significant portion of the debt assumed in the transaction during the first half of 2017. In December 2017, a purchase price reduction of $9 was agreed under the sale and purchase agreement provisions for determination of the net indebtedness and net working capital levels of BFP and BPT as of the closing date. The terms of the agreement provided Dana the right to call half of Brevini’s noncontrolling interests in BFP and BPT, and Brevini the right to put half of its noncontrolling interests in BFP and BPT to Dana, assuming Dana did not exercise its call right, after the 2017 BFP and BPT financial statements had been approved by the board of directors. Further, Dana had the right to call Brevini’s remaining noncontrolling interests in BFP and BPT, and Brevini the right to put its remaining noncontrolling interests in BFP and BPT to Dana, assuming Dana does not exercise its call right, after the 2019 BFP and BPT financial statements had been approved by the board of directors. The call and put prices were based on the amount Dana paid to acquire its initial 80% interest in BFP and BPT subject to adjustment based on the actual EBITDA and free cash flows, as defined in the agreement, of BFP and BPT. In connection with the acquisition of BFP and BPT, Dana agreed to purchase certain real estate being leased by BPT from a Brevini affiliate for €25. Completion of the real estate purchase and receipt of the purchase price adjustment occurred in the second quarter of 2018 with a net cash payment of $20. The purchase consideration and the related allocation to the acquisition date fair values of the assets acquired and liabilities assumed are presented in the following table:



Total purchase consideration	$	201

Cash and cash equivalents	$	75
Accounts receivable - Trade	78

Total purchase consideration allocation	$	201

Goodwill recognized in this transaction is primarily attributable to synergies expected to arise after the acquisition and the assembled workforce and is not deductible for tax purposes. Intangibles includes $29 allocated to customer relationships and $12 allocated to trademarks and trade names. We used the multi-period excess earnings method, an income approach, to value the customer relationships. We used the relief from royalty method, an income approach, to value trademarks and trade names. We used a replacement cost method to value fixed assets. We used a discounted cash flow approach to value the redeemable noncontrolling interests, inclusive of the put and call provisions. We used both discounted cash flow and cost approaches to value the noncontrolling interests. The customer relationships and trademarks and trade names intangible assets are being amortized on a straight-line basis over seventeen years, and property, plant and equipment is being depreciated on a straight-line basis over useful lives ranging from three to thirty years.

The results of operations of the businesses are reported in our Off-Highway operating segment from the date of acquisition. Transaction related expenses in 2017 associated with completion of the acquisition totaling $7 were charged to other income (expense), net. The pro forma effects of this acquisition would not materially impact our reported results for any period presented, and as a result no pro forma financial statements are presented. During 2017, the businesses contributed sales of $401.

On August 8, 2018, we entered into an agreement to acquire Interfind S.p.A.'s, formerly Brevini Group S.p.A., remaining 20% ownership interests in BFP and BPT and to settle all claims between the parties. We paid $43 to acquire Interfind S.p.A.'s remaining ownership interests and received $10 in settlement of all pending and future claims. See Note 9 for additional information.

SIFCO — On December 23, 2016, we acquired strategic assets of SIFCO S.A.'s (SIFCO) commercial vehicle steer axle systems and related forged components businesses. The acquisition enables us to enhance our vertically integrated supply chain, which will further improve our cost structure and customer satisfaction by leveraging SIFCO's extensive experience and knowledge of sophisticated forged components. In addition to strengthening our position as a central source for products that use forged and machined parts throughout the region, this acquisition enables us to better accommodate the local content requirements of our customers, which reduces their import and other region-specific costs.

SIFCO contributed the strategic assets to SJT Forjaria Ltda., a newly created legal entity, and Dana acquired all of the issued and outstanding quotas of SJT Forjaria Ltda. The strategic assets were acquired by Dana free and clear of any liens, claims or encumbrances. The acquisition was funded using cash on hand and has been accounted for as a business combination. Dana paid $60 at closing and paid $3 of previously deferred consideration during the fourth quarter of 2017. On December 19, 2017, Dana and SIFCO reached an agreement providing for Dana to retain the remaining $7 of deferred consideration to satisfy indemnification claims as they arise. During 2018, claim settlements reduced the retained purchase price by $2. Once all indemnification claims have been satisfied, any remaining deferred consideration will be paid to SIFCO. The purchase consideration and the related allocation to the acquisition date fair values of the assets acquired are presented in the following table:



Total purchase consideration	$	70

Accounts receivable - Trade	$	1
Accounts receivable - Other	1
Inventories	10
Goodwill	7
Intangibles	3
Property, plant and equipment	59
Accounts payable	(2		)
Accrued payroll and employee benefits	(9		)
Total purchase consideration allocation	$	70

Goodwill recognized in this transaction is primarily attributable to synergies expected to arise after the acquisition and the assembled workforce, and is deductible for tax purposes. Intangibles includes $2 allocated to developed technology and $1 allocated to trade names. We used the relief from royalty method, an income approach, to value developed technology and trade names. We used a replacement cost method to value fixed assets. The developed technology and trade name intangible assets are being amortized on a straight-line basis over seven and five years, respectively, and property, plant and equipment is being depreciated on a straight-line basis over useful lives ranging from three to ten years.

The results of operations of the business are reported in our Commercial Vehicle operating segment from the date of acquisition. As a result of the acquisition, we incurred transaction related expenses totaling $5, which were charged to other income (expense), net. The pro forma effects of this acquisition would not materially impact our reported results for any period presented, and as a result no pro forma financial statements were presented.

Magnum — On January 29, 2016, we acquired the aftermarket distribution business of Magnum^® Gaskets (Magnum), a U.S.-based supplier of gaskets and sealing products for automotive and commercial-vehicle applications, for a cash payment of $18. Assets acquired included trademarks and trade names, customer relationships and goodwill. The results of operations of Magnum are reported within our Power Technologies operating segment. We acquired Magnum using cash on hand. The pro forma effects of this acquisition would not materially impact our reported results for any period presented, and as a result no pro forma financial statements were presented.

Disposal Groups and Divestitures

Disposal group held for sale — In December 2017, we entered into an agreement to divest our Brazil suspension components business (the disposal group) for no consideration to an unaffiliated company. The results of operations of the Brazil suspension components business are reported within our Commercial Vehicle operating segment. To effectuate the sale, Dana was obligated to contribute $10 of additional cash to the business prior to closing. We classified the disposal group as held for sale at December 31, 2017, recognizing a $27 loss to adjust the carrying value of the net assets to fair value and to recognize the liability for the additional cash required to be contributed to the business prior to closing. During the first quarter of 2018, we made the required cash contribution to the disposal group. After being unable to complete the transaction with the counterparty to the December 2017 agreement, we entered into an agreement with another third party in June 2018. The transaction with the new counterparty closed in July 2018 and we received cash proceeds of $2. We reversed $3 of the previously recognized $27 pre-tax loss, inclusive of the proceeds received in July 2018, during the second quarter of 2018. The carrying amounts of the major classes of assets and liabilities of our Brazil suspension components business were as follows:



	December 31, 2017
Accounts receivable - Trade	$	3
Inventories	4
Current assets classified as held for sale	$	7

Accounts payable	$	3
Accrued payroll and employee benefits	1
Other accrued liabilities	1
Current liabilities classified as held for sale	$	5

Other noncurrent liabilities	$	2
Noncurrent liabilities classified as held for sale	$	2

Divestiture of Dana Companies — On December 30, 2016, we completed the divestiture of Dana Companies, LLC (DCLLC), a consolidated wholly-owned limited liability company that was established as part of our reorganization in 2008 to hold and manage personal injury asbestos claims retained by the reorganized Dana Corporation which was merged into DCLLC. DCLLC had net assets of $165 at the time of sale including cash and cash equivalents, marketable securities and rights to insurance coverage in place to satisfy a significant portion of its liabilities. We received cash proceeds of $88 – $29 net of cash divested – with $3 retained by the purchaser subject to the satisfaction of certain future conditions. We recognized a pre-tax loss of $77 in 2016 upon completion of the transaction. During the second quarter of 2017 the conditions associated with the retained purchase price were satisfied. Dana received the remaining proceeds and recognized $3 of income in other income (expense), net. Following completion of the sale, Dana has no obligation with respect to current or future asbestos claims.

Divestiture of Nippon Reinz — On November 30, 2016, we sold our 53.7% interest in Nippon Reinz Co. Ltd. (Nippon Reinz) to Nichias Corporation. Dana received net cash proceeds of $5 and recognized a pre-tax loss of $3 on the divestiture of Nippon Reinz, inclusive of the $12 gain on derecognition of the noncontrolling interest. Nippon Reinz had sales of $42 in 2016 through the transaction date.

Goodwill and Other Intangible Assets

Goodwill —The change in the carrying amount of goodwill in 2018 was due to the acquisition of a 55% interest in TM4 and currency fluctuation. The change in the carrying amount of goodwill in 2017 was primarily due to the acquisitions of USM – Warren and 80% interests in BFP and BPT and currency fluctuation. See Note 2 for additional information on recent acquisitions. Based on our October 31, 2018 impairment assessment, the fair value of our reporting units are higher than their carrying values, indicating no impairment.

Non-amortizable intangible assets — Our non-amortizable intangible assets include trademarks and trade names. Trademarks and trade names consist of the Dana^®, Spicer^® and TM4^® trademarks and trade names utilized in our Commercial Vehicle and Off-Highway segments. We value trademarks and trade names using a relief from royalty method which is based on revenue streams. No impairment was recorded during the three years ended December 31, 2018 in connection with the required annual assessment for trademarks and trade names.

During the third quarter of 2012, we entered a strategic alliance with Fallbrook Technologies Inc. (Fallbrook). The transaction with Fallbrook was accounted for as a business combination and the original purchase price allocation included $20 of intangible assets used in research and development activities, which had been classified as indefinite-lived. Since the third quarter of 2012, we have been working with several customers to commercialize the continuously variable planetary (CVP) technology primarily in combustion engine applications. During the second quarter of 2018 key customers notified us of their intention to redirect their development efforts to electrification and cease further development efforts of the CVP technology in combustion engine applications. While we have not abandoned the CVP technology, we determined that it was more likely than not that the fair value of the related intangible assets was less than their carrying amount. We used the multi-period excess earnings method, an income approach, to fair value the assets used in research and development activities. Given the lack of adequate identifiable future revenue streams, it was determined that the $20 of intangible assets used in research and development activities was fully impaired during the second quarter of 2018.

Amortizable intangible assets — Our amortizable intangible assets include core technology, customer relationships and a portion of our trademarks and trade names. Trademarks and trade names includes the Brevini^® trademark and trade name utilized in our Off-Highway segment. Core technology includes the proprietary know-how and expertise that is inherent in our products and manufacturing processes. Customer relationships include the established relationships with our customers and the related ability of these customers to continue to generate future recurring revenue and income.

These assets are tested for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. We group the assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the undiscounted future cash flows. We use our internal forecasts, which we update quarterly, to develop our cash flow projections. These forecasts are based on our knowledge of our customers’ production forecasts, our assessment of market growth rates, net new business, material and labor cost estimates, cost recovery agreements with customers and our estimate of savings expected from our restructuring activities. The most likely factors that would significantly impact our forecasts are changes in customer production levels and loss of significant portions of our business. Our valuation is applied over the life of the primary assets within the asset groups. If the undiscounted cash flows do not indicate that the carrying amount of the asset group is recoverable, an impairment charge is recorded if the carrying amount of the asset group exceeds its fair value based on discounted cash flow analyses or appraisals. There were no impairments recorded during the three years ended December 31, 2018.

Restructuring and Related Activities [Abstract]

Restructuring of Operations [Text Block]

Restructuring of Operations

Our restructuring activities have historically included rationalizing our operating footprint by consolidating facilities, positioning operations in lower cost locations and reducing overhead costs. In recent years, our focus has primarily been headcount reduction initiatives to reduce operating costs. Restructuring expense includes costs associated with current and previously announced actions and is comprised of contractual and noncontractual separation costs and exit costs, including costs associated with lease continuation obligations and certain operating costs of facilities that we are in the process of closing.

During 2018, we implemented headcount and cost reduction initiatives across our operating segments and corporate functions. Restructuring charges of $25 in 2018 were primarily comprised of severance and benefit costs related to a voluntary retirement program in North America, headcount reduction actions in our operations and corporate functions in Brazil and administrative cost reduction initiatives primarily in Europe and North America. In response to continued market recovery in our Off-Highway business in Europe, management re-evaluated the economic conditions of our global Off-Highway business and determined that $7 of the previously approved restructuring actions are no longer economically prudent.

During 2017, we approved plans to implement certain headcount reduction initiatives in our Off-Highway business as part of the BFP and BPT acquisition integration, resulting in the recognition of $14, primarily for severance and benefits costs, during 2017. Including costs associated with the newly approved actions during 2017 and costs associated with previously announced initiatives, net of the reversal described below, restructuring expense during 2017 was $14, including $8 of severance and benefits costs and $6 of exit costs. During the fourth quarter of 2017, in response to better-than-expected market recovery in our Off-Highway business in Europe, management re-evaluated the economic conditions of our global Off-Highway business and determined that a portion of the previously approved 2016 restructuring program is no longer economically prudent. This change in facts and circumstances led to the decision to reverse $8 of previously accrued liabilities.

During 2016, we implemented various headcount reduction initiatives across our businesses, including the first-quarter 2016 announcement of the planned closure of our Commercial Vehicle manufacturing facility in Glasgow, Kentucky. During the second half of 2016, we also approved and began to implement other headcount reduction initiatives, the most significant of which were associated with our Off-Highway business in Europe and our Commercial Vehicle and Light Vehicle businesses in Brazil, in response to continued market weakness in those businesses at that time. Additionally, in conjunction with the SJT Forjaria Ltda. acquisition in December 2016, we approved plans to eliminate certain redundant positions as one of our initial steps toward the integration of the SJT Forjaria Ltda. operations into our Commercial Vehicle business in that region. Including costs associated with these actions and with other previously announced initiatives, total restructuring expense during 2016 was $36, including $33 of severance and benefits costs and $3 of exit costs.

Stockholders' Equity

Preferred Stock

We are authorized to issue 50,000,000 of Dana preferred stock, par value $0.01 per share. There were no preferred shares outstanding at December 31, 2018 or 2017.

Common Stock

We are authorized to issue 450,000,000 shares of Dana common stock, par value $0.01 per share. At December 31, 2018, there were 153,005,588 shares of our common stock issued and 144,663,403 shares outstanding, net of 8,342,185 in treasury shares. Treasury shares include those shares withheld at cost to satisfy tax obligations from stock awards issued under our stock compensation plan in addition to share repurchases noted below.

Our Board of Directors declared a quarterly cash dividend of ten cents per share of common stock in each quarter of 2018. Aggregate 2018 declared dividends total $59 and paid cash dividends total $58. Dividends accrue on restricted stock units (RSUs) granted under our stock compensation program and will be paid in cash or additional units when the underlying units vest.

Share repurchase program — On March 24, 2018 our Board of Directors approved an expansion of our existing common stock share repurchase program to $200. The program expires on December 31, 2019. Under the program, we spent $25 to repurchase 1,055,000 shares of our common stock during the second quarter of 2018 through open market transactions. Approximately $175 remained available under the program for future share repurchases as of December 31, 2018. Our common stock share repurchase program of up to $1,700 approved in 2016 expired on December 31, 2017.

Changes in equity —

During the first quarter of 2018, a wholly-owned subsidiary of Dana purchased the ownership interest in Dana Spicer (Thailand) Limited (a non wholly-owned consolidated subsidiary of Dana) held by ROC Spicer, Ltd. (a non wholly-owned consolidated subsidiary of Dana). Dana maintained its controlling financial interest in Dana Spicer (Thailand) Limited and accordingly accounted for the purchase as an equity transaction. The excess of the fair value of the consideration paid over the carrying value of the investment attributable to the noncontrolling interest in ROC Spicer, Ltd. was recognized as additional noncontrolling interest with a corresponding reduction of the additional paid-in capital of Dana. During the third quarter of 2018, Yulon Motor Co., Ltd. (Yulon) purchased a direct ownership interest in two of our consolidated operating subsidiaries. Yulon's ownership interest in the two consolidated operating subsidiaries did not change as a result of the transactions, as it previously owned the same percentages indirectly through a series of consolidated holding companies. The cash received from Yulon was recognized as additional noncontrolling interest. The amount received, less withholding taxes, was returned to Yulon in the form of a dividend in the fourth quarter of 2018.

Redeemable Noncontrolling Interests

Temporary Equity Disclosure [Abstract]

Redeemable Noncontrolling Interest Disclosure [Text Block]

Redeemable Noncontrolling Interests

In connection with the acquisition of a controlling interest in TM4 from Hydro-Québec on June 22, 2018, we recognized $102 for Hydro-Québec's 45% redeemable noncontrolling interest. The terms of the agreement provide Hydro-Québec with the right to put all, and not less than all, of its shares to Dana at fair value any time after June 22, 2021. See Note 2 for additional information.

In connection with the acquisition of a controlling interest in BFP and BPT from Brevini on February 1, 2017, we recognized $44 for Brevini's 20% redeemable noncontrolling interests. The terms of the agreement provided Dana the right to call Brevini's noncontrolling interests in BFP and BPT, and Brevini the right to put its noncontrolling interests in BFP and BPT to Dana, assuming Dana did not exercise its call rights, at dates and prices defined in the agreement. The call and put prices were based on the amount Dana paid to acquire its initial ownership interest in BFP and BPT subject to adjustment based on the actual EBITDA and free cash flows, as defined in the agreement, of BFP and BPT.

On August 8, 2018, we entered into an agreement to acquire Brevini's remaining 20% ownership interests in BFP and BPT and to settle all claims between the parties. We paid $43 to acquire Brevini's remaining ownership interests and received $10 in settlement of all pending and future claims. AOCI attributable to Brevini's redeemable noncontrolling interests was reclassified to AOCI of the parent company. The difference between the carrying value of Brevini's redeemable noncontrolling interests and the cash paid was recorded to additional paid-in capital of the parent company. See Note 2 for additional information.

Redeemable noncontrolling interests reflected as of the balance sheet date are the greater of the redeemable noncontrolling interest balances adjusted for comprehensive income items and distributions or the redemption values. Redeemable noncontrolling interest adjustments of redemption value are recorded in retained earnings. During 2017 there was a $6 adjustment to reflect a redemption value in excess of carrying value. See Note 10 for additional information.

2017 Omnibus Incentive Plan

The 2017 Omnibus Incentive Plan (the Plan) authorizes the grant of stock options, stock appreciation rights (SARs), RSUs and performance share units (PSUs) through April 2027. Cash-settled awards do not count against the maximum aggregate number. At December 31, 2018, there were 5.6 million shares available for future grants. Shares of common stock to be issued under the Plan are made available from authorized and unissued Dana common stock.

Compensation expense is generally measured based on the fair value at the date of grant and is recognized on a straight-line basis over the vesting period. For options and SARs, we use an option-pricing model to estimate fair value. For RSUs and PSUs, the fair value is based on the closing market price of our common stock at the date of grant. Awards that are settled in cash are subject to liability accounting. Accordingly, the fair value of such awards is remeasured at the end of each reporting period until settled or expired. We had accrued $2 and $7 for cash-settled awards at December 31, 2018 and 2017. We issued 0.7 million and 0.2 million shares of common stock based on vesting of RSUs and PSUs during 2018. At December 31, 2018, the total unrecognized compensation cost related to the nonvested awards granted and expected to vest was $20. This cost is expected to be recognized over a weighted-average period of 1.7 years.

Stock options and stock appreciation rights — The exercise price of each option or SAR equals the closing market price of our common stock on the date of grant. Options and SARs generally vest over three years and their maximum term is ten years. Shares issued upon the exercise of options are recorded as common stock and additional paid-in capital at the option price. SARs are settled in cash for the difference between the market price on the date of exercise and the exercise price. We have not granted stock options or SARs since 2013. All outstanding awards are fully vested and exercisable. At December 31, 2018, the outstanding awards have an aggregate intrinsic value of $1 and a weighted-average remaining contractual life of 3.1 years.

Restricted stock units and performance shares units — Each RSU or PSU granted represents the right to receive one share of Dana common stock or, at the election of Dana (for units awarded to board members) or for employees located outside the U.S. (for employee awarded units), cash equal to the market value per share. All RSUs contain dividend equivalent rights. RSUs granted to non-employee directors vest on the first anniversary date of the grant and those granted to employees generally cliff vest fully after three years. PSUs granted to employees vest if specified performance goals are achieved during the respective performance period, generally three years.

The number of PSUs that ultimately vest is contingent on achieving specified return on invested capital targets, specified total shareholder return targets relative to peer companies or specified margin targets. For the portion of the PSU award based on the return on invested capital performance or margin metric, we estimated the fair value at grant date based on the closing market price of our common stock at the date of grant adjusted for the value of assumed dividends over the period because the award is not dividend protected. The estimated grant date value is accrued over the performance period and adjusted as appropriate based on performance relative to the target. For the portion of the PSU award based on shareholder returns, we estimated the fair value at grant date using various assumptions as part of a Monte Carlo simulation. The expected term represents the period from the grant date to the end of the performance period. The risk-free interest rate was based on U.S. Treasury constant maturity rates at the grant date. The dividend yield was calculated by dividing the expected annual dividend by the average stock price over the prior year. The expected volatility was based on historical volatility using daily stock price observations.

We make awards annually to certain eligible employees designated by Dana, including certain executive officers. Awards under the plan are based on achieving certain financial performance goals. The performance goals of the plan are established annually by the Board of Directors.

Under the 2018 and 2017 annual incentive programs, participants were eligible to receive cash awards based on achieving earnings and cash flow performance goals. The 2016 annual incentive program is based on earnings and working capital performance goals. Our 2017 and 2016 long-term incentive programs each have a three-year contractual vesting period and include a performance-based cash component. For the 2017 and 2016 long-term incentive programs the vesting of the performance-based cash component is based on achieving a return on invested capital target measured on an average basis over the contractual period. The 2017 award also has a component that is based on achieving a margin target in the third year of the program that was established at the grant date. We accrued $33, $77 and $41 of expense in 2018, 2017 and 2016 for the expected cash payments under these programs.

Pension and Postretirement Benefit Plans

We sponsor various defined benefit, qualified and nonqualified, pension plans covering eligible employees. Other postretirement benefits (OPEB), including medical and life insurance, are provided for certain employees upon retirement.

We also sponsor various defined contribution plans that cover the majority of our employees. Under the terms of the qualified defined contribution retirement plans, employee and employer contributions may be directed into a number of diverse investments. None of these qualified defined contribution plans allow direct investment in our stock.

Our U.S. defined benefit pension plans are frozen and no additional service cost is being accrued. The estimated net actuarial loss for the defined benefit pension plans that will be amortized from AOCI into benefit cost in 2019 is $21 for our U.S. plans and $6 for our non-U.S. plans. We use the corridor approach for purposes of systematically amortizing deferred gains or losses as a component of net periodic benefit cost into the income statement in future reporting periods. The amortization period used is generally the average remaining service period of active participants in the plan unless almost all of the plan’s participants are inactive, in which case we use the average remaining life expectancy of the inactive participants. No portion of the estimated net actuarial gain related to OPEB plans will be amortized from AOCI into benefit cost in 2019.

In October 2017, upon authorization by the Dana Board of Directors, we commenced the process of terminating one of our U.S. defined benefit pension plans. Ultimate plan termination is subject to prevailing market conditions and other considerations, including interest rates and annuity pricing. Settlement of the plan obligations is expected to occur in the first half of 2019. At December 31, 2018, this plan had benefit obligations of $938 and assets of $773. The benefit obligations have been valued at the amount expected to be required to settle the obligations, using assumptions regarding the portion of obligations expected to be settled through participant acceptance of lump sum payments or annuities and the cost to purchase those annuities. Increasing this plan's obligations to reflect the expected settlement value resulted in an actuarial loss of $69 that was charged to OCI in 2017. At December 31, 2018, this plan had unrecognized actuarial losses of $370. If the settlement is effected as expected in 2019, the plan's deferred actuarial losses remaining in AOCI at that time will be recognized as expense.

The 2018 actuarial loss of $11 on the U.S plans was largely the result of the expected return on assets exceeding the actual asset return. Additionally, a custom mortality table was developed during 2018 using our historical mortality experience. These custom mortality tables are projected generationally from 2015 using the Society of Actuaries projection scale, MP-2018, modified to use a 0.75% long-term improvement rate, being attained in 2027.

Excluding the actuarial loss of $69 for remeasurement of the benefit obligations of the plan being terminated at expected settlement value, we recognized an actuarial gain of $47 on the U.S. plans in 2017 as the return on assets exceeding the expected rate more than offset the effect of the lower discount rates used to value our December 31, 2017 pension obligations and the impact of using spot rates to determine pension service and interest expense, as discussed previously. In the fourth quarter of 2017, the Society of Actuaries continued its trend of frequent updates, issuing new U.S. mortality scales (MP-2017) based on historical data through 2014 and preliminary data for 2015. After studying the new data and consulting with our actuarial advisers, we concluded that adopting MP-2017, modified to reflect a long-term improvement rate of 0.75% being attained in 2026, was appropriate. This change in assumption did not have a significant impact on the 2017 valuation.

Valuation Methods

Equity securities — The fair value of equity securities held directly by the trust is based on quoted market prices. When the equity securities are held in commingled funds that are not publicly traded, the fair value of our interest in the fund is its NAV as determined by quoted market prices for the underlying holdings.

Fixed income securities — The fair value of fixed income securities held directly by the trust is based on a bid evaluation process with input from independent pricing sources. When the fixed income securities are held in commingled funds that are not publicly traded, the fair value of our interest in the fund is its NAV as determined by a similar valuation of the underlying holdings.

Insurance contracts — The values shown for insurance contracts are the amounts reported by the insurance company and approximate the fair values of the underlying investments.

Real estate — The investments in real estate represent ownership interests in commingled funds and partnerships that invest in real estate. The investment managers determine the NAV of these ownership interests using the fair value of the underlying real estate which is obtained via independent third party appraisals prepared on a periodic basis. Assumptions used to value the properties are updated quarterly. For the component of the real estate portfolio under development, the investments are carried at cost until they are completed and valued by a third party appraiser.

Cash and cash equivalents — The fair value of cash and cash equivalents is set equal to its amortized cost.

The methods described above may produce a fair value that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Investment policy — Target asset allocations of U.S. pension plans are established through an investment policy, which is updated periodically and reviewed by an Investment Committee, comprised of certain company officers. The investment policy allows for a flexible asset allocation mix which is intended to provide appropriate diversification to lessen market volatility while assuming a reasonable level of economic risk.

Our policy recognizes that properly managing the relationship between pension assets and pension liabilities serves to mitigate the impact of market volatility on our funding levels. The investment policy permits plan assets to be invested in a number of diverse categories, including a Growth Portfolio, an Immunizing Portfolio and a Liquidity Portfolio. These sub-portfolios are intended to balance the generation of incremental returns with the management of overall risk.

The Growth Portfolio is invested in a diversified pool of assets in order to generate an incremental return with an acceptable level of risk. The Immunizing Portfolio is a hedging portfolio that may be comprised of fixed income securities and overlay positions. This portfolio is designed to offset changes in the value of the pension liability due to changes in interest rates. The Liquidity Portfolio is a cash portfolio designed to meet short-term liquidity needs and reduce the plans’ overall risk. As a result of our diversification strategies, there are no significant concentrations of risk within the portfolio of investments.

The allocations among portfolios are adjusted as needed to meet changing objectives and constraints and to manage the risk of adverse changes in the unfunded positions of our plans. Following approval of the plan of termination by our Board of Directors in October 2017, the Investment Committee established new targets for the assets of the subject plan. At December 31, 2018, the plan that we expect to terminate had targets of 0% in the Growth Portfolio (U.S. and non-U.S. equities, high-yield fixed income, real estate, emerging market debt and cash), 98% in the Immunizing Portfolio (long duration U.S. Treasury strips, corporate bonds and cash) and 2% in the Liquidity Portfolio (cash and short-term securities) while the remaining U.S. plans had targets of 45% for the Growth Portfolio, 53% for the Immunizing Portfolio and 2% for the Liquidity Portfolio. The assets held at December 31, 2018 by the plan we expect to terminate were invested 5% in the Growth Portfolio, 94% in the Immunizing Portfolio and 1% in the Liquidity Portfolio while the assets held by the remaining U.S. plans were invested 42% in the Growth Portfolio, 56% in the Immunizing Portfolio and 2% in the Liquidity Portfolio. The Investment Committee is in the process of implementing the adjustments to the asset allocation.

Significant assumptions — The significant weighted-average assumptions used in the measurement of pension benefit obligations at December 31 of each year and the net periodic benefit cost for each year are as follows:



	2018				2017				2016
	U.S.		Non-U.S.		U.S.		Non-U.S.		U.S.		Non-U.S.
Pension benefit obligations:
Discount rate	4.22	%	2.42	%	3.55	%	2.25	%	3.92	%	2.48	%
Net periodic benefit cost:
Discount rate	2.56	%	2.54	%	3.24	%	2.34	%	3.29	%	2.56	%
Rate of compensation increase	N/A		3.21	%	N/A		3.33	%	N/A		3.12	%
Expected return on plan assets	6.00	%	4.66	%	6.00	%	5.92	%	6.50	%	5.42	%

The pension plan discount rate assumptions are evaluated annually in consultation with our outside actuarial advisers. Long-term interest rates on high quality corporate debt instruments are used to determine the discount rate. For our largest plans, discount rates are developed using a discounted bond portfolio analysis, with appropriate consideration given to defined benefit payment terms and duration of the liabilities. As disclosed previously, the obligations of the U.S. plan being terminated have been remeasured at expected settlement value. Based on the timing and settlement payments, the U.S. plan being terminated has an implied discount rate of 3.46%. In the above table, the discount rate used to determine U.S. pension obligations at the end of 2017 and 2018 does not consider the plan we expect to terminate.

We had historically estimated the interest and service cost components of net periodic benefit cost for pension and other postretirement benefits using a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation of the plan at the most recent remeasurement date. At December 31, 2015, we changed the method used to estimate those interest and service components for pension and other postretirement benefit plans that utilize a yield curve approach. The new method uses a full yield curve approach to estimate the interest and service components by applying the specific spot rates along the yield curve used in the most recent remeasurement of the benefit obligation to the relevant projected cash flows. We believe this method improves the correlation between the projected cash flows and the corresponding interest rates and provides a more precise measurement of interest and service costs. Since the remeasurement of total benefit obligations is not affected, the resulting reduction in periodic benefit cost is offset by an increase in the actuarial loss.

The expected rate of return on plan assets was selected on the basis of our long-term view of return and risk assumptions for major asset classes. We define long-term as forecasts that span at least the next ten years. Our long-term outlook is influenced by a combination of return expectations by individual asset class, actual historical experience and our diversified investment strategy. We consult with and consider the opinions of financial professionals in developing appropriate capital market assumptions. Return projections are also validated using a simulation model that incorporates yield curves, credit spreads and risk premiums to project long-term prospective returns. The appropriateness of the expected rate of return is assessed on an annual basis and revised if necessary. We have a high percentage of total assets in fixed income securities since the benefit accruals are frozen for all of our U.S. pension plans. Based on this assessment, we have selected a 6.00% expected return on asset assumption for 2019 for our U.S. plans not being terminated. The asset portfolio of the U.S. plan expected to be terminated has a higher proportion of assets invested in fixed income investments. As such, we selected an expected rate of 3.80% for this plan.

The significant weighted-average assumptions used in the measurement of OPEB obligations at December 31 of each year and the net periodic benefit cost for each year are as follows:



	OPEB - Non-U.S.
	2018		2017		2016
OPEB benefit obligations:
Discount rate	3.71	%	3.41	%	3.69	%
Net periodic benefit cost:
Discount rate	3.42	%	3.70	%	3.45	%
Initial health care cost trend rate	4.12	%	5.07	%	5.32	%
Ultimate health care cost trend rate	5.10	%	5.07	%	5.02	%
Year ultimate reached	2023		2018		2018

The discount rate selection process was similar to the process used for the pension plans. Assumed health care cost trend rates have a significant effect on the health care obligation. To determine the trend rates, consideration is given to the plan design, recent experience and health care economics.

A one-percentage-point change in assumed health care cost trend rates would have the following effects for 2018:



	1% Point Increase		1% Point Decrease
Effect on total of service and interest cost components	$	1	$	(1	)
Effect on OPEB obligations	8		(7		)

Estimated future benefit payments and contributions — Expected benefit payments by our pension and OPEB plans for each of the next five years and for the following five-year period are as follows:



	Pension Benefits				OPEB
Year	U.S.		Non-U.S.		Non-U.S.
2019	$	1,001	$	25	$	5
2020	43		15		5
2021	42		15		5
2022	42		17		5
2023	41		17		5
2024 to 2028	191		103		24
Total	$	1,360	$	192	$	49

Pension benefits are funded through deposits with trustees that satisfy, at a minimum, the applicable funding regulations. OPEB benefits are funded as they become due. Projected contributions to be made during 2019 to the defined benefit pension plans are $16 for our non-U.S. plans. Based on the current funded status of our U.S. plans, there are no minimum contributions required for 2019. 2019 benefit payments include the impact of the termination of the U.S. defined benefit pension plan discussed above.

Multi-employer pension plans — We participate in the Steelworkers Pension Trust (SPT) multi-employer pension plan which provides pension benefits to all of our U.S. employees represented by the United Steelworkers and United Automobile Workers unions. Contributions are made in accordance with our collective bargaining agreements and rates are generally based on hours worked. The collective bargaining agreements expire August 18, 2021. The trustees of the SPT have provided us with the latest data available for the plan year ended December 31, 2018. As of that date, the plan is not fully funded. We could be held liable to the plan for our obligations as well as those of other employers as a result of our participation in the plan. Contribution rates could increase if the plan is required to adopt a funding improvement plan or a rehabilitation plan, if the performance of plan assets does not meet expectations or as a result of future collectively bargained wage and benefit agreements. If we choose to stop participating in the plan, we may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

The Pension Protection Act (PPA) defines a zone status for each plan. Plans in the green zone are at least 80% funded, plans in the yellow zone are at least 65% funded and plans in the red zone are generally less than 65% funded. The SPT plan has utilized extended amortization provisions to amortize its losses from 2008. The plan recertified its zone status after using the extended amortization provisions as allowed by law. The SPT plan has not implemented a funding improvement or rehabilitation plan, nor are such plans pending. Our contributions to the SPT exceeded 5% of the total contributions to the plan.

Senior notes activity — On September 18, 2017, we redeemed the remaining $350 of our September 2021 Notes at a price equal to 102.688% plus accrued and unpaid interest. The $13 loss on extinguishment of debt includes the $10 redemption premium and the $3 write-off of previously deferred financing costs associated with the September 2021 Notes.

On April 4, 2017, Dana Financing Luxembourg S.à r.l., a wholly-owned subsidiary of Dana, issued $400 in senior notes (April 2025 Notes) at 5.750%, which are guaranteed by Dana. The April 2025 Notes were issued through a private placement and will not be registered under the U.S. Securities Act of 1933, as amended (the Securities Act). The April 2025 Notes were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act and, outside the United States, only to non-U.S. investors in reliance on Regulation S under the Securities Act. The April 2025 Notes rank equally with Dana's other unsecured senior notes. Interest on the notes is payable on April 15 and October 15 of each year. The April 2025 Notes will mature on April 15, 2025. Net proceeds of the offering totaled $394. Financing costs of $6 were recorded as deferred costs and are being amortized to interest expense over the life of the April 2025 Notes. The proceeds from the offering were used to repay indebtedness of our BPT and BFP subsidiaries, repay indebtedness of a wholly-owned subsidiary in Brazil, redeem $100 of our September 2021 Notes and for general corporate purposes. The September 2021 Notes were redeemed on April 4, 2017 at a price equal to 104.031% plus accrued and unpaid interest. The $6 loss on extinguishment of debt includes the $4 redemption premium and the $1 write-off of previously deferred financing costs associated with the September 2021 Notes and the $1 redemption premium associated with the repayment of indebtedness of a wholly-owned subsidiary in Brazil. In conjunction with the issuance of the April 2025 Notes, we entered into 8-year fixed-to-fixed cross-currency swaps which have the effect of economically converting the April 2025 Notes to euro-denominated debt at a fixed rate of 3.850%. See Note 15 for additional information.

On June 23, 2016, we redeemed all of our February 2021 Notes at a price equal to 103.375% plus accrued and unpaid interest. The $16 loss on extinguishment of debt includes the $12 redemption premium and the $4 write-off of previously deferred financing costs associated with the February 2021 Notes.

On May 27, 2016, Dana Financing Luxembourg S.à r.l., a wholly-owned subsidiary of Dana, issued $375 in senior notes (June 2026 Notes).

The June 2026 Notes were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act and, outside the United States, only to non-U.S. investors in reliance on Regulation S under the Securities Act. The June 2026 Notes rank equally with Dana's other unsecured senior notes. Interest on the notes is payable on June 15 and December 15 of each year. The June 2026 Notes will mature on June 1, 2026. Net proceeds of the offering totaled $368. Financing costs of $7 were recorded as deferred costs and are being amortized to interest expense over the life of the notes. The proceeds from the offering were used to redeem our February 2021 Notes, to pay related fees and expenses and for general corporate purposes.

Senior notes redemption provisions — We may redeem some or all of the senior notes at the following redemption prices (expressed as percentages of principal amount), plus accrued and unpaid interest to the redemption date, if redeemed during the 12-month period commencing on the anniversary date of the senior notes in the years set forth below:



	Redemption Price

2024					100.000	%	100.000	%
2025							100.000	%

Prior to December 15, 2019, we may redeem some or all of the December 2024 Notes at a price equal to the principal amount thereof, plus accrued and unpaid interest, plus a “make-whole” premium. We have not separated the make-whole premium from the underlying debt instrument to account for it as a derivative instrument as the economic characteristics and the risks of this embedded derivative are clearly and closely related to the economic characteristics and risks of the underlying debt.

At any time prior to April 15, 2020, we may redeem up to 35% of the aggregate principal amount of the April 2025 Notes in an amount not to exceed the amount of proceeds of one or more equity offerings, at a price equal to 105.750% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, provided that at least 50% of the original aggregate principal amount of the April 2025 Notes remains outstanding after the redemption.

Prior to April 15, 2020, we may redeem some or all of the April 2025 Notes at a redemption price of 100.000% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date plus a “make-whole” premium. We have not separated the make-whole premium from the underlying debt instrument to account for it as a derivative instrument as the economic characteristics and the risks of this embedded derivative are clearly and closely related to the economic characteristics and risks of the underlying debt.

At any time prior to June 1, 2019, we may redeem up to 35% of the aggregate principal amount of the June 2026 Notes in an amount not to exceed the amount of proceeds of one or more equity offerings, at a price equal to 106.500% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, provided that at least 50% of the original aggregate principal amount of the June 2026 Notes remains outstanding after the redemption.

Prior to June 1, 2021, we may redeem some or all of the June 2026 Notes at a redemption price of 100.000% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date plus a “make-whole” premium. We have not separated the make-whole premium from the underlying debt instrument to account for it as a derivative instrument as the economic characteristics and the risks of this embedded derivative are clearly and closely related to the economic characteristics and risks of the underlying debt.

Credit agreement — On August 17, 2017, we entered into an amended credit and guaranty agreement comprised of a $275 term facility (the Term Facility) and a $600 revolving credit facility (the Revolving Facility) both of which mature on August 17, 2022. On September 14, 2017, we drew the entire amount available under the Term Facility. Net proceeds from the Term Facility draw totaled $274. Financing costs of $1 were recorded as deferred cost and are being amortized to interest expense over the life of the Term Facility. We are required to make equal quarterly installments on the last day of each fiscal quarter of 1.5625% of the initial aggregate principal amount of the Term Facility commencing on September 30, 2018. We may prepay some or all of Term Facility without penalty. Any prepayments made on the Term Facility would be applied against the required quarterly installments. The proceeds from the Term Facility were used to repay our September 2021 Notes and for general corporate purposes. The Revolving Facility amended our previous revolving credit facility. In connection with the Revolving Facility, we paid $2 in deferred financing costs to be amortized to interest expense over the life of the facility. Deferred financing costs on our Revolving Facility are included in other noncurrent assets.

The Term Facility and the Revolving Facility are guaranteed by all of our wholly-owned domestic subsidiaries subject to certain exceptions (the guarantors) and grants a first-priority lien on substantially all of the assets of Dana and the guarantors, subject to certain exceptions.

Advances under the Term Facility and Revolving Facility bear interest at a floating rate based on, at our option, the base rate or Eurodollar rate (each as described in the revolving credit agreement) plus a margin as set forth below:



	Margin
Total Net Leverage Ratio	Base Rate		Eurodollar Rate
Less than or equal to 1.00:1.00	0.50	%	1.50	%
Greater than 1.00:1.00 but less than or equal to 2.00:1.00	0.75	%	1.75	%
Greater than 2.00:1.00	1.00	%	2.00	%

We have elected to pay interest on our advance under the Term Facility at the Eurodollar Rate. The interest rates on the Term Facility, inclusive of the applicable margin, was 4.27238% as of December 31, 2018.

Commitment fees are applied based on the average daily unused portion of the available amounts under the Revolving Facility as set forth below:



Total Net Leverage Ratio	Commitment Fee
Less than or equal to 1.00:1.00	0.250	%
Greater than 1.00:1.00 but less than or equal to 2.00:1.00	0.375	%
Greater than 2.00:1.00	0.500	%

Up to $275 of the Revolving Facility may be applied to letters of credit, which reduces availability. We pay a fee for issued and undrawn letters of credit in an amount per annum equal to the applicable margin for Eurodollar rate advances based on a quarterly average availability under issued and undrawn letters of credit under the Revolving Facility and a per annum fronting fee of 0.125%, payable quarterly.

At December 31, 2018, we had no outstanding borrowings under the Revolving Facility but we had utilized $21 for letters of credit. We had availability at December 31, 2018 under the Revolving Facility of $579 after deducting the outstanding letters of credit.

Debt covenants — At December 31, 2018, we were in compliance with the covenants of our financing agreements. Under the Term Facility, Revolving Facility and the senior notes, we are required to comply with certain incurrence-based covenants customary for facilities of these types and, in the case of the Term Facility and Revolving Facility, a maintenance covenant requiring us to maintain a first lien net leverage ratio not to exceed 2.00 to 1.00.

Fair Value Measurements and Derivatives [Text Block]

Fair Value Measurements and Derivatives

In measuring the fair value of our assets and liabilities, we use 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.

Fair value measurements on a recurring basis — Assets and liabilities that are carried in our balance sheet at fair value are as follows:



			Fair Value
Category	Balance Sheet Location	Fair Value Level	December 31, 2018		December 31, 2017
Available-for-sale securities	Marketable securities	1	$	—	$	5
Available-for-sale securities	Marketable securities	2	21		35
Currency forward contracts
Cash flow hedges	Accounts receivable - Other	2	6		1
Cash flow hedges	Other accrued liabilities	2	5		5
Undesignated	Accounts receivable - Other	2	2		1
Undesignated	Other accrued liabilities	2	1		3
Currency swaps
Cash flow hedges	Other noncurrent liabilities	2	118		177

Fair Value Level 1 assets and liabilities reflect quoted prices in active markets. Fair Value Level 2 assets and liabilities reflect the use of significant other observable inputs.

Fair value of financial instruments — The financial instruments that are not carried in our balance sheet at fair value are as follows:



	2018				2017
	Carrying Value		Fair Value		Carrying Value		Fair Value
Senior notes	$	1,500	$	1,442	$	1,500	$	1,592
Term Facility	265		265		275		275
Other indebtedness*	28		23		29		22
Total	$	1,793	$	1,730	$	1,804	$	1,889


*	The carrying value includes the unamortized portion of a fair value adjustment related to a terminated interest rate swap at both dates. The carrying value and fair value also include a financial liability associated with certain build-to-suit lease arrangements at December 31, 2017.

The fair value of our senior notes and Term Facility are estimated based upon a market approach (Level 2) while the fair value of our other indebtedness is based upon an income approach (Level 2). The fair value of the Term Facility approximates its carrying value as it is a floating-rate facility. See Note 14 for additional information about financing arrangements.

Fair value measurements on a nonrecurring basis — Certain assets are measured at fair value on a nonrecurring basis. These are long-lived assets that are subject to fair value adjustments only in certain circumstances. These assets include intangible assets and property, plant and equipment which may be written down to fair value when they are held for sale or as a result of impairment.

Interest rate derivatives — Our portfolio of derivative financial instruments periodically includes interest rate swaps designed to mitigate our interest rate risk. As of December 31, 2018, no fixed-to-floating interest rate swaps remain outstanding. However, a $6 fair value adjustment to the carrying amount of our December 2024 Notes, associated with a fixed-to-floating interest rate swap that had been executed but was subsequently terminated during 2015, remains deferred at December 31, 2018. This amount is being amortized as a reduction of interest expense through the period ending December 2024, the scheduled maturity date of the December 2024 Notes. Approximately $1 was amortized as a reduction of interest expense during 2018.

Foreign currency derivatives — Our foreign currency derivatives include forward contracts associated with forecasted transactions, primarily involving the purchases and sales of inventory through the next eighteen months, as well as currency swaps associated with certain recorded external notes payable and intercompany loans receivable and payable. Periodically, our foreign currency derivatives also include net investment hedges of certain of our investments in foreign operations.

In 2017, in conjunction with the issuance of €281 of euro-denominated intercompany notes payable, issued by certain of our Luxembourg subsidiaries (the "Luxembourg Intercompany Notes") and payable to USD-functional Dana, Inc., we executed fixed-to-fixed cross-currency swaps with the same critical terms as the Luxembourg Intercompany Notes. The risk management objective of these swaps is to eliminate the variability in the functional-currency-equivalent cash flows due to changes in the euro / U.S. dollar exchange rates associated with the forecasted principal and interest payments.

In 2017, in conjunction with the issuance of the $400 of U.S. dollar-denominated April 2025 Notes by euro-functional Dana Financing Luxembourg S.à r.l., we executed fixed-to-fixed cross-currency swaps with the same critical terms as the April 2025 Notes to eliminate the variability in the functional-currency-equivalent cash flows due to changes in the U.S. dollar / euro exchange rates associated with the forecasted principal and interest payments.

In 2016, in conjunction with the issuance of the $375 of U.S. dollar-denominated June 2026 Notes by euro-functional Dana Financing Luxembourg S.à r.l., we executed fixed-to-fixed cross-currency swaps with the same critical terms as the June 2026 Notes to eliminate the variability in the functional-currency-equivalent cash flows due to changes in the U.S. dollar / euro exchange rates associated with the forecasted principal and interest payments.

All of the underlying designated financial instruments, and any subsequent replacement debt, have been designated as the hedged items in each respective cash flow hedge relationship, as shown in the table below. Designated as cash flow hedges of the forecasted principal and interest payments of the underlying designated financial instruments, or subsequent replacement debt, all of the swaps economically convert the underlying designated financial instruments into the functional currency of each respective holder. The impact of the interest rate differential between the inflow and outflow rates on all fixed-to-fixed cross-currency swaps is recognized during each period as a component of interest expense.

The following fixed-to-fixed cross-currency swaps were outstanding at December 31, 2018:



Underlying Financial Instrument						Derivative Financial Instrument
Description	Type	Face Amount		Rate		Designated Notional Amount		Traded Amount		Inflow Rate		Outflow Rate
June 2026 Notes	Payable	$	375	6.50	%	$	375	€	338	6.50	%	5.14	%
April 2025 Notes	Payable	$	400	5.75	%	$	400	€	371	5.75	%	3.85	%
Luxembourg Intercompany Notes	Receivable	€	281	3.91	%	€	281	$	300	6.00	%	3.91	%

All of the swaps are expected to be highly effective in offsetting the corresponding currency-based changes in cash outflows related to the underlying designated financial instruments. Based on our qualitative assessment that the critical terms of all of the underlying designated financial instruments and all of the associated swaps match and that all other required criteria have been met, we do not expect to incur any ineffectiveness. As effective cash flow hedges, changes in the fair value of the swaps will be recorded in OCI during each period. Additionally, to the extent the swaps remain effective, the appropriate portion of AOCI will be reclassified to earnings each period as an offset to the foreign exchange gain or loss resulting from the remeasurement of the underlying designated financial instruments. See Note 14 for additional information about the June 2026 Notes and the April 2025 Notes. To the extent the swaps are no longer effective, changes in their fair values will be recorded in earnings.

The total notional amount of outstanding foreign currency forward contracts, involving the exchange of various currencies, was $1,007 at December 31, 2018 and $306 at December 31, 2017. The total notional amount of outstanding foreign currency swaps, including the fixed-to-fixed cross-currency swaps, was $1,097 at December 31, 2018 and $1,112 at December 31, 2017.

The following currency derivatives were outstanding at December 31, 2018:



		Notional Amount (U.S. Dollar Equivalent)

Total currency swaps		1,097		—		1,097
Total currency derivatives		$	1,407	$	697	$	2,104

During the third quarter of 2018, we entered into a Swiss franc notional deal contingent forward to economically hedge the purchase price relating to the planned acquisition of the Drive Systems segment of the Oerlikon Group.

Cash flow hedges — With respect to contracts designated as cash flow hedges, changes in fair value during the period in which the contracts remain outstanding are reported in OCI to the extent such contracts remain effective. 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. Changes in fair value of contracts not designated as cash flow hedges or as net investment hedges are recognized in other income (expense), net in the period in which the changes occur. Realized gains and losses from currency-related forward contracts associated with forecasted transactions or from other derivative instruments, including those that have been designated as cash flow hedges and those that have not been designated, are recognized in the same line item in the consolidated statement of operations in which the underlying forecasted transaction or other hedged item is recorded. Accordingly, amounts are potentially recorded in sales, cost of sales or, in certain circumstances, other income (expense), net.

The following table provides a summary of the impact on AOCI of derivative instruments that have been designated as cash flow hedges:



	Derivatives in Cash Flow Hedging Relationships
	Forward Contracts			Cross-Currency Swaps			Total Cash Flow Hedges
Balance in AOCI at December 31, 2017, before tax	$	(4	)	$	(64	)	$	(68	)
Gain (loss) recorded in OCI	7			59			66
(Gain) loss reclassified from AOCI to the consolidated statement of operations	(1		)	(55		)	(56		)
Balance in AOCI at December 31, 2018, before tax	$	2		(60		)	$	(58	)

The following table provides a summary of the location and amount of gains or losses recognized in the consolidated statement of operations associated with cash flow hedging relationships:



	Location and Amount of Gain or (Loss) Recognized in Income on Cash Flow Hedging Relationships
	2018
Derivatives Designated as Cash Flow Hedges	Net sales		Cost of sales			Other income (expense), net
Total amounts of income and expense line items presented in the consolidated statement of operations in which the effects of cash flow hedges are recorded	$	8,143	$	6,986		$	(29	)
(Gain) or loss on cash flow hedging relationships
Foreign currency forwards
Amount of (gain) loss reclassified from AOCI into income			(1		)
Cross-currency swaps
Amount of (gain) loss reclassified from AOCI into income						(55		)

The amounts reclassified from AOCI into income for the cross-currency swaps represent an offset to a foreign exchange loss on our foreign currency-denominated intercompany and external debt instruments.

Certain of our hedges of forecasted transactions have not formally been designated as cash flow hedges. As undesignated forward contracts, the changes in the fair value of such contracts are included in earnings for the duration of the outstanding forward contract. Any realized gain or loss on the settlement of such contracts is recognized in the same period and in the same line item in the consolidated statement of operations as the underlying transaction. The following table provides a summary of the location and amount of gains or losses recognized in the consolidated statement of operations associated with undesignated hedging relationships.



2018
Derivatives Not Designated as Hedging Instruments	Amount of Gain (Loss) Recognized in Income			Location of Gain or (Loss) Recognized in Income
Foreign currency forward contracts	$	(5	)	Cost of sales
Foreign currency forward contracts	(5		)	Other income (expense), net

Net investment hedges — We periodically designate derivative contracts or underlying non-derivative financial instruments as net investment hedges. With respect to contracts designated as net investment hedges, we apply the forward method, but for non-derivative financial instruments designated as net investment hedges, we apply the spot method. Under both methods, we report changes in fair value in the CTA component of OCI during the period in which the contracts remain outstanding to the extent such contracts and non-derivative financial instruments remain effective.

In 2017, we designated the principal amount of an existing non-derivative Mexican peso-denominated intercompany note payable (the "MXN-denominated intercompany note") by Dana European Holdings Luxembourg S.à r.l. to Dana de Mexico Corporacion S. de R.L. de C.V., one of our Mexican subsidiaries, as a net investment hedge of the equivalent portion of the investment in the associated Mexican operations. During the third quarter of 2018 the intercompany note was repaid and no additional net investment hedges are outstanding. On a cumulative basis, a deferred loss of $4 has been recorded in the CTA component of AOCI for this non-derivative instrument. Amounts recorded in CTA remain deferred in AOCI until such time as the investments in the associated subsidiaries are substantially liquidated.

Amounts to be reclassified to earnings — Deferred gains or losses associated with effective cash flow hedges of forecasted transactions are reported in AOCI and are reclassified to earnings in the same periods in which the underlying transactions affect earnings. Amounts expected to be reclassified to earnings assume no change in the current hedge relationships or to December 31, 2018 exchange rates. Deferred gains of $2 at December 31, 2018 are expected to be reclassified to earnings during the next twelve months, compared to deferred losses of $4 at December 31, 2017. Amounts reclassified from AOCI to earnings arising from the discontinuation of cash flow hedge accounting treatment were not material during 2018.

Commitments and Contingencies

Product liabilities — We had accrued $19 and $7 for product liability costs at December 31, 2018 and 2017. We had also recognized $24 and $9 as expected amounts recoverable from third parties at the respective dates. The increases in the liability and recoverable amounts at December 31, 2018 largely reflect the recognition of the estimated cost, net of payments made, and the expected recovery of an insured matter. Payments made to claimants have preceded the recovery of amounts from third parties, resulting in a recoverable amount in excess of the total liability at December 31, 2018. We estimate these liabilities based on current information and assumptions about the value and likelihood of the claims against us.

Environmental liabilities — Accrued environmental liabilities were $10 and $8 at December 31, 2018 and 2017. We consider the most probable method of remediation, current laws and regulations and existing technology in estimating our environmental liabilities.

Guarantee of lease obligations — In connection with the divestiture of our Structural Products business in 2010, leases covering three U.S. facilities were assigned to a U.S. affiliate of Metalsa. Under the terms of the sale agreement, we will guarantee the affiliate’s performance under the leases, which run through June 2025, including approximately $6 of annual payments. In the event of a required payment by Dana as guarantor, we are entitled to pursue full recovery from Metalsa of the amounts paid under the guarantee and to take possession of the leased property.

Other legal matters — We are subject to various pending or threatened legal proceedings arising out of the normal course of business or operations. In view of the inherent difficulty of predicting the outcome of such matters, we cannot state what the eventual outcome of these matters will be. However, based on current knowledge and after consultation with legal counsel, we believe that any liabilities that may result from these proceedings will not have a material adverse effect on our liquidity, financial condition or results of operations.

Lease commitments — Cash obligations under future minimum rental commitments under operating leases and net rental expense at December 31, 2018 are shown in the table below. Operating lease commitments are primarily related to facilities.

Income tax audits — We conduct business globally and, as a result, file income tax returns in multiple jurisdictions that are subject to examination by taxing authorities throughout the world. With few exceptions, we are no longer subject to U.S. federal, state and local or foreign income tax examinations for years before 2009.

We are currently under audit by U.S. and foreign authorities for certain taxation years. When the issues related to these periods are settled, the total amounts of unrecognized tax benefits for all open tax years may be modified. Audit outcomes and the timing of the audit settlements are subject to uncertainty and we cannot make an estimate of the impact on our financial position at this time.

U.S. tax reform legislation — On December 22, 2017, the Tax Cuts and Jobs Act ("Act") was signed into law in the U.S. The Act includes a broad range of tax reforms, certain of which were required by GAAP to be recognized upon enactment. The U.S. Securities and Exchange Commission has issued Staff Accounting Bulletin 118 (SAB 118), which provides guidance on accounting for the tax effects of the Act. SAB 118 provides a measurement period that should not extend beyond one year from the enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Act.

Based on our historical financial performance in the U.S., at December 31, 2017, we had a significant net deferred tax asset position. As such, with the Act's reduction of the corporate tax rate from 35% to 21%, we remeasured our net deferred tax assets at the lower corporate rate of 21% and recognized tax expense to adjust net deferred tax assets to the reduced value. The Act introduced provisions that fundamentally change the U.S. approach to taxation of foreign earnings. Under the Act, qualified dividends of foreign subsidiaries are no longer subject to U.S. tax. Under the previously-existing tax rules, dividends from foreign operations were subjected to U.S. tax, and if not considered permanently reinvested, we had recognized expense and recorded a liability for the tax expected to be incurred upon receipt of the dividend of these foreign earnings. Although the Act excludes dividends of foreign subsidiaries from taxation, it included a provision for a mandatory deemed dividend of undistributed foreign earnings at tax rates of 15.5% or 8% ("transition tax") depending on the nature of the foreign operations' assets. Companies may utilize tax attributes (including net operating losses and tax credits) to offset the transition tax. The estimated net effect of applying the provisions of the Act on our 2017 results of operations was a non-cash charge to tax expense of $186. Our analysis of this provisional amount continued throughout the year as additional guidance and interpretations of the Act were issued, and we completed our accounting for the provisions of the Act in the fourth quarter of 2018, with no material adjustment required.

Beginning in 2018, the Act may also trigger a taxable deemed dividend to the extent that the annual earnings of our foreign subsidiaries exceed a specified threshold, based on the value of tangible foreign operating assets. The deemed dividend, if any, from this global intangible low-taxed income (GILTI) may be offset by the use of other tax attributes in that year, and specifically, the GILTI rules may impact the amount of cash tax savings that net operating losses provide. The SEC staff has indicated that a company should make and disclose certain policy elections related to accounting for GILTI. As to whether we will recognize deferred taxes for basis differences expected to reverse as GILTI or account for the effect of GILTI as a period cost when incurred, we intend to account for the tax effect of GILTI as a period cost. As to the realizability of the tax benefit provided by net operating losses, we are electing to utilize the tax law ordering approach.

During 2018, we recognized a benefit of $44 related to U.S. state law changes and the development and implementation of a tax planning strategy which adjusted federal tax credits, along with federal and state net operating losses and the associated valuation allowances. We also recognized benefits of $11 relating to the reversal of a provision for an uncertain tax position, $5 relating to the release of valuation allowances in the US based on improved income projections and $7 due to permanent reinvestment assertions. Partially offsetting these benefits was $5 of expense to settle outstanding tax matters in a foreign jurisdiction.

The net effect in 2017 of applying the U.S. tax reform provisions of the Act was tax expense of $186. This impact, which increased the effective rate for 2017 by 49%, was principally attributable to the reduction of net deferred tax assets to reflect the reduced corporate tax rate. Foreign tax credits of $49 which were generated in 2017 but not utilized to offset the transition tax are included as a benefit in the credits and incentives component of the effective rate reconciliation, with an offsetting expense of $49 in the valuation allowance component to recognize that such credits are not likely to be realized.

In the fourth quarter of 2016, we determined that valuation allowances against certain U.S. deferred taxes were no longer required. Release of these valuation allowances resulted in $501 of tax benefit. Valuation allowances against U.S. deferred tax assets primarily related to state operating loss carryforwards and other credits were retained. In the fourth quarter of 2017, based on our improved financial performance and outlook, we determined that release of an additional $27 was appropriate and recognized a tax benefit of this amount. Developments in Brazil in 2016 led to our determination that an allowance against certain deferred taxes in that country was appropriate, and we recognized tax expense of $25 in 2016 to establish this valuation allowance.

Foreign income repatriation — Prior to the U.S. tax reform provisions enacted with passage of the Act, we provided for U.S. federal income and non-U.S. withholding taxes on the earnings of our non-U.S. operations that are not considered to be permanently reinvested. As indicated above, with passage of the Act, dividends of earnings from non-U.S. operations are generally no longer subjected to U.S. income tax. Accordingly, in the fourth quarter of 2017, we reduced the previously recorded liability for U.S. income tax on expected repatriations of non-U.S. earnings. We continue to analyze and adjust the estimated impact of the non-U.S. income and withholding tax liabilities based on the amount and source of these earnings, as well as the expected means through which those earnings may be taxed. We recognized a net benefit of $7 in 2018, net expense of $2 in 2017, and a net benefit of $58 in 2016 related to future income taxes and non-U.S. withholding taxes on repatriations from operations that are not permanently reinvested. We also paid withholding taxes of $11, $7 and $6 during 2018, 2017 and 2016 related to the actual transfer of funds to the U.S. The unrecognized tax liability associated with the operations in which we are permanently reinvested is $11 at December 31, 2018.

The earnings of our certain non-U.S. subsidiaries may be repatriated to the U.S. in the form of repayments of intercompany borrowings. Certain of our international operations had intercompany loan obligations to the U.S. totaling $1,040 at the end of 2018. Included in this amount are intercompany loans and related interest accruals with an equivalent value of $21 which are denominated in a foreign currency and considered to be permanently invested.

Valuation allowance adjustments — We have recorded valuation allowances in several entities where the recent history of operating losses does not allow us to satisfy the “more likely than not” criterion for the recognition of deferred tax assets. Consequently, there is no income tax expense or benefit recognized on the pre-tax income or losses in these jurisdictions as valuation allowances are adjusted to offset the associated tax expense or benefit.

When evaluating the need for a valuation allowance we consider all components of comprehensive income, and we weigh the positive and negative evidence, putting greater reliance on objectively verifiable evidence than on projections of future profitability that are dependent on actions that have not occurred as of the assessment date. We also consider changes to the historical financial results due to activities that were either new to the business or not expected to recur in the future, in order to identify the core earnings of the business. A sustained period of profitability, after considering changes to the historical results due to implemented actions and nonrecurring events, along with positive expectations for future profitability are necessary to reach a determination that a valuation allowance should be released. We believe it is reasonably possible that a valuation allowance of up to $24 related to a subsidiary in Brazil will be released in the next twelve months.

At December 31, 2016, we retained a valuation allowance of $137 against deferred tax assets in the U.S. primarily related to state operating loss carryforwards and other credits which do not meet the more likely than not criterion for releasing the valuation allowance. Based on our financial performance and outlook, we determined that $5 and $27 of this allowance met the more-likely-than not standard for release in 2018 and 2017.

Carryforwards — Our deferred tax assets include benefits expected from the utilization of net operating loss (NOL), capital loss and credit carryforwards in the future. The following table identifies the net operating loss deferred tax asset components and the related allowances that existed at December 31, 2018. Due to time limitations on the ability to realize the benefit of the carryforwards, additional portions of these deferred tax assets may become unrealizable in the future.



	Deferred Tax Asset		Valuation Allowance			Carryforward Period	Earliest Year of Expiration
Net operating losses
U.S. federal	$	76	$	—		20	2029
U.S. state	88		(41		)	Various	2019

China	2		(2		)	5	2020
Total	$	255	$	(122	)

In addition to the NOL carryforwards listed in the table above, we have deferred tax assets related to capital loss carryforwards of $40 which are fully offset with valuation allowances at December 31, 2018. We also have deferred tax assets of $232 related to other credit carryforwards which are partially offset with $95 of valuation allowances at December 31, 2018. The capital losses can be carried forward indefinitely while the other credits are generally available for 10 to 20 years.

The use of our $362 U.S. federal NOL as of December 31, 2018 is subject to limitation due to the change in ownership of our stock upon emergence from bankruptcy. Generally, the application of the relevant Internal Revenue Code (IRC) provisions will release the limitation on $84 of pre-change NOLs each year, allowing pre-change losses to offset post-change taxable income. However, there can be no assurance that trading in our shares will not effect another change in ownership under the IRC which could further limit our ability to utilize our available NOLs.

Unrecognized tax benefits — Unrecognized tax benefits are the difference between a tax position taken, or expected to be taken, in a tax return and the benefit recognized for accounting purposes. Interest income or expense, as well as penalties relating to income tax audit adjustments and settlements, are recognized as components of income tax expense or benefit. Interest of $11 and $11 was accrued on the uncertain tax positions at December 31, 2018 and 2017.

Reconciliation of gross unrecognized tax benefits —



	2018			2017			2016
Balance, beginning of period	$	119		$	117		$	87
Decrease related to expiration of statute of limitations	(4		)	(3		)	(5		)
Decrease related to prior years tax positions	(15		)	(25		)	(1		)
Increase related to prior years tax positions	8			15			28
Increase related to current year tax positions	10			15			8
Decrease related to settlements	(11		)
Balance, end of period	$	107		$	119		$	117

The 2017 decrease related to prior years tax positions includes $23 that resulted from the reduction of the U.S. income tax rate from 35% to 21% since these positions represent a reduction of U.S. net operating losses. We anticipate that our gross unrecognized tax benefits will decrease by $16 in the next twelve months upon the expected completion of examinations in various jurisdictions. The settlement of these matters will not impact the effective tax rate. Gross unrecognized tax benefits of $86 would impact the effective tax rate if recognized. If other open matters are settled with the IRS or other taxing jurisdictions, the total amounts of unrecognized tax benefits for open tax years may be modified.

Foreign exchange gains and losses on cross-currency intercompany loan balances that are not of a long-term investment nature are included above. Foreign exchange gains and losses on intercompany loans that are permanently invested are reported in OCI.

Strategic transaction expenses relate primarily to costs incurred in connection with acquisition and divestiture related activities, including costs to complete the transaction and post-closing integration costs. Strategic transaction expenses in 2018 were primarily attributable to our bid to acquire the driveline business of GKN plc., our acquisition of an ownership interest in TM4, our pending acquisition of the Drive Systems segment of the Oerlikon Group and integration costs associated with our acquisitions of BFP and BPT, and were partially offset by a $40 transaction breakup fee associated with the GKN plc. transaction. Strategic transaction expenses in 2017 are primarily attributable to our acquisitions of USM - Warren, BFP and BPT. Strategic transaction expenses in 2016 are primarily attributable to our acquisition of SJT Forjaria Ltda. and our divestitures of DCLLC and Nippon Reinz. See Notes 2 and 3 for additional information.

Amounts attributable to previously divested/closed operations includes the receipt of the remaining proceeds on our December 2016 divestiture of DCLLC during the second quarter of 2017. See Note 3 for additional information. During 2016, DCLLC received $8 as recovery of costs previously incurred on behalf of other participants in a consortium that existed to administer certain legacy personal injury claims, and they sold investments which generated $7 of gain.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers [Text Block]

Revenue from Contracts with Customers

We generate revenue from selling production parts to original equipment manufacturers (OEMs) and service parts to OEMs and aftermarket customers. While we provide production and service parts to certain OEMs under awarded multi-year programs, these multi-year programs do not contain any commitment to volume by the customer. As such, individual customer releases or purchase orders represent the contract with the customer. Our customer contracts do not provide us with an enforceable right to payment for performance completed to date throughout the contract term. As such, we recognize part sales revenue at the point in time when the parts are shipped, and risk of loss has transferred to the customer. We have elected to continue to include shipping and handling fees billed to customers in revenue, while including costs of shipping and handling in costs of sales. Taxes collected from customers are excluded from revenues and credited directly to obligations to the appropriate government agencies. Payment terms with our customers are established based on industry and regional practices and generally do not exceed 180 days.

Certain of our customer contracts include rebate incentives. We estimate expected rebates and accrue the corresponding refund liability, as a reduction of revenue, at the time covered product is sold to the customer based on anticipated customer purchases during the rebate period and contractual rebate percentages. Under prior accounting guidance rebate reserves were reflected as a reduction of accounts receivable - trade as rebates are generally net settled through the issuance of a credit to the customer's account. Refund liabilities are included in other accrued liabilities on our consolidated balance sheet. We provide standard fitness for use warranties on the products we sell, accruing for estimated costs related to product warranty obligations at time of sale. See Note 17 for additional information.

Contract liabilities are primarily comprised of cash deposits made by customers with cash in advance payment terms. Generally, our contract liabilities turn over frequently given our relatively short production cycles. Contract liabilities were $12 and $9 at December 31, 2018 and January 1, 2018. Contract liabilities are included in other accrued liabilities on our consolidated balance sheet.

Upon our adoption of ASU 2017-07 on January 1, 2018, we changed our measurement of segment profit to exclude the non-service cost components of pension and OPEB costs. See Note 1 for additional information on ASU 2017-07. Prior period segment EBITDA amounts have not been recast due to the insignificance of the adjustments. Had the prior period amounts been recast to conform with the current presentation, segment EBITDA for 2017 and 2016 would have been $359 and $275 for Light Vehicle, $119 and $98 for Commercial Vehicle, $213 and $130 for Off-Highway and $173 and $163 for Power Technologies.

Key Assumptions as Part of Monte Carlo Simulation Model [Table Text Block]

For the portion of the PSU award based on shareholder returns, we estimated the fair value at grant date using various assumptions as part of a Monte Carlo simulation. The expected term represents the period from the grant date to the end of the performance period. The risk-free interest rate was based on U.S. Treasury constant maturity rates at the grant date. The dividend yield was calculated by dividing the expected annual dividend by the average stock price over the prior year. The expected volatility was based on historical volatility using daily stock price observations.
