Organization, Consolidation and Presentation of Financial Statements [Abstract]

Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by these financial statements and accompanying notes. Actual results could differ from those estimates.

Consolidations

Principles of consolidation The Consolidated Financial Statements include all majority-owned subsidiaries with a controlling financial interest. All inter-company accounts and transactions have been eliminated in consolidation. Investments in 20% to 50% owned affiliates are accounted for under the equity method when the Company does not have a controlling financial interest.

Revenue recognition

Revenue recognition The Company recognizes revenue when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of our products. Although the Company may enter into long-term supply arrangements with its major customers, the prices and volumes are not fixed over the life of the arrangements, and a contract does not exist for purposes of applying ASC 606 until volumes are contractually known. For most of our products, transfer of control occurs upon shipment or delivery, however, a limited number of our customer arrangements for our highly customized products with no alternative use provide us with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer. Revenue is measured at the amount of consideration we expect to receive in exchange for transferring the good.

The Company continually seeks business development opportunities and at times provides customer incentives for new program awards. Customer incentive payments are capitalized when the payments are incremental and incurred only if the new business is obtained and these amounts are expected to be recovered from the customer over the term of the new business arrangement. The Company recognizes a reduction to revenue as products that the upfront payments are related to are transferred to the customer, based on the total amount of products expected to be sold over the term of the arrangement (generally 3 to 7 years). The Company evaluates the amounts capitalized each period end for recoverability and expenses any amounts that are no longer expected to be recovered over the term of the business arrangement.

Cost of sales

Cost of sales The Company includes materials, direct labor and manufacturing overhead within cost of sales. Manufacturing overhead is comprised of indirect materials, indirect labor, factory operating costs and other such costs associated with manufacturing products for sale.

Cash

Cash Cash is valued at fair market value. It is the Company's policy to classify all highly liquid investments with original maturities of three months or less as cash. Cash is maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and therefore bear minimal risk.

Receivables, net

Receivables, net Accounts receivable are stated at cost less an allowance for bad debts. An allowance for doubtful accounts is recorded when it is probable amounts will not be collected based on specific identification of customer circumstances or age of the receivable.

Refer to Note 6, "Balance Sheet Information," to the Consolidated Financial Statements for more information.

Inventories, net

Inventories, net Cost of certain U.S. inventories is determined using the last-in, first-out (“LIFO”) method at the lower of cost or market, while other U.S. and foreign operations use the first-in, first-out (“FIFO”) or average-cost methods at the lower of cost or net realizable value. Inventory held by U.S. operations using the LIFO method was $137.9 million and $147.4 million at December 31, 2018 and 2017, respectively. Such inventories, if valued at current cost instead of LIFO, would have been greater by $16.7 million and $13.1 million at December 31, 2018 and 2017, respectively.

Refer to Note 6, "Balance Sheet Information," to the Consolidated Financial Statements of this report for more information.

Pre-production costs related to long-term supply arrangements

Pre-production costs related to long-term supply arrangements Engineering, research and development and other design and development costs for products sold on long-term supply arrangements are expensed as incurred unless the Company has a contractual guarantee for reimbursement from the customer. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has title to the assets are capitalized in property, plant and equipment and amortized to cost of sales over the shorter of the term of the arrangement or over the estimated useful lives of the assets, typically three to five years. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has a contractual guarantee for lump sum reimbursement from the customer are capitalized in prepayments and other current assets.

Property, plant and equipment and depreciation, net

Property, plant and equipment, net Property, plant and equipment is valued at cost less accumulated depreciation. Expenditures for maintenance, repairs and renewals of relatively minor items are generally charged to expense as incurred. Renewals of significant items are capitalized. Depreciation is generally computed on a straight-line basis over the estimated useful lives of the assets. Useful lives for buildings range from 15 to 40 years and useful lives for machinery and equipment range from three to 12 years. For income tax purposes, accelerated methods of depreciation are generally used.

Refer to Note 6, "Balance Sheet Information," to the Consolidated Financial Statements for more information.

Impairment or disposal of long-lived assets, including intangible assets, policy

Impairment of long-lived assets, including definite-lived intangible assets The Company reviews the carrying value of its long-lived assets, whether held for use or disposal, including other amortizing intangible assets, when events and circumstances warrant such a review under Accounting Standards Codification ("ASC") Topic 360. In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. In assessing long-lived assets for impairment, management generally considers individual facilities the lowest level for which identifiable cash flows are largely independent. A recoverability review is performed using the undiscounted cash flows if there is a triggering event. If the undiscounted cash flow test for recoverability identifies a possible impairment, management will perform a fair value analysis. Management determines fair value under ASC Topic 820 using the appropriate valuation technique of market, income or cost approach. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value.

Management believes that the estimates of future cash flows and fair value assumptions are reasonable; however, changes in assumptions underlying these estimates could affect the valuations. Significant judgments and estimates used by management when evaluating long-lived assets for impairment include: (i) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (ii) undiscounted future cash flows generated by the asset; and (iii) fair valuation of the asset.

Assets and liabilities held for sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale.

Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the Consolidated Balance Sheets. Additionally, depreciation is not recorded during the period in which the long-lived assets, included in the disposal group, are classified as held for sale.

Goodwill and other indefinite-lived intangible assets

Goodwill and other indefinite-lived intangible assets During the fourth quarter of each year, the Company qualitatively assesses its goodwill assigned to each of its reporting units. This qualitative assessment evaluates various events and circumstances, such as macro economic conditions, industry and market conditions, cost factors, relevant events and financial trends, that may impact a reporting unit's fair value. Using this qualitative assessment, the Company determines whether it is more-likely-than-not the reporting unit's fair value exceeds its carrying value. If it is determined that it is not more-likely-than-not the reporting unit's fair value exceeds the carrying value, or upon consideration of other factors, including recent acquisition, restructuring or divestiture activity, the Company performs a quantitative, "step one," goodwill impairment analysis. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could more-likely-than-not reduce the fair value of a reporting unit below its carrying value.

Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (primarily trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion in order to determine if it is more-likely-than-not that the fair value of the trade names is less than the respective carrying values. If the Company elects to perform or is required to perform a quantitative analysis, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. We estimate the fair value of indefinite-lived intangibles using the relief-from-royalty method, which we believe is an appropriate and widely used valuation technique for such assets. The fair value derived from the relief-from-royalty method is measured as the discounted cash flow savings realized from owning such trade names and not being required to pay a royalty for their use.

Refer to Note 7, "Goodwill and Other Intangibles," to the Consolidated Financial Statements for more information.

Product warranties

Product warranties The Company provides warranties on some, but not all, of its products. The warranty terms are typically from one to three years. Provisions for estimated expenses related to product warranty are made at the time products are sold. These estimates are established using historical information about the nature, frequency and average cost of warranty claim settlements as well as product manufacturing and industry developments and recoveries from third parties. Management actively studies trends of warranty claims and takes action to improve product quality and minimize warranty claims. Management believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the accrual. The product warranty accrual is allocated to current and non-current liabilities in the Consolidated Balance Sheets.

Refer to Note 8, "Product Warranty," to the Consolidated Financial Statements for more information.

Other loss accruals and valuation allowances

Other loss accruals and valuation allowances The Company has numerous other loss exposures, such as customer claims, workers' compensation claims, litigation and recoverability of assets. Establishing loss accruals or valuation allowances for these matters requires the use of estimates and judgment in regard to the risk exposure and ultimate realization. The Company estimates losses under the programs using consistent and appropriate methods, however, changes to its assumptions could materially affect the recorded accrued liabilities for loss or asset valuation allowances.

Asbestos

Asbestos Like many other industrial companies that have historically operated in the United States, the Company, or parties that the Company is obligated to indemnify, continues to be named as one of many defendants in asbestos-related personal injury actions. With the assistance of a third party actuary, the Company estimates the liability and corresponding insurance recovery for pending and future claims not yet asserted through December 31, 2064 with a runoff through 2074 and defense costs. This estimate is based on the Company's historical claim experience and estimates of the number and resolution cost of potential future claims that may be filed based on anticipated levels of unique plaintiff asbestos-related claims in the U.S. tort system against all defendants. This estimate is not discounted to present value. The Company currently believes that December 31, 2074 is a reasonable assumption as to the last date on which it is likely to have resolved all asbestos-related claims, based on the nature and useful life of the Company’s products and the likelihood of incidence of asbestos-related disease in the U.S. population generally. The Company assesses the sufficiency of its estimated liability for pending and future claims not yet asserted and defense costs on an ongoing basis by evaluating actual experience regarding claims filed, settled and dismissed, and amounts paid in claim resolution costs. In addition to claims experience, the Company considers additional quantitative and qualitative factors such as changes in legislation, the legal environment, and the Company's defense strategy. The Company continues to have additional excess insurance coverage available for potential future asbestos-related claims. In connection with the Company’s ongoing review of its asbestos-related claims, the Company also reviewed the amount of its potential insurance coverage for such claims, taking into account the remaining limits of such coverage, the number and amount of claims on our insurance from co-insured parties, ongoing litigation against the Company’s insurance carriers, potential remaining recoveries from insolvent insurance carriers, the impact of previous insurance settlements, and coverage available from solvent insurance carriers not party to the coverage litigation.

Refer to Note 15, "Contingencies," to the Consolidated Financial Statements for more information.

Environmental cost, expense policy

Environmental contingencies The Company accounts for environmental costs in accordance with ASC Topic 450. Costs related to environmental assessments and remediation efforts at operating facilities are accrued when it is probable that a liability has been incurred and the amount of that liability can be reasonably estimated. Estimated costs are recorded at undiscounted amounts, based on experience and assessments and are regularly evaluated. The liabilities are recorded in accounts payable and accrued expenses and other non-current liabilities in the Company's Consolidated Balance Sheets.

Refer to Note 15, "Contingencies," to the Consolidated Financial Statements for more information.

Derivatives, reporting of derivative activity

Derivative financial instruments The Company recognizes that certain normal business transactions generate risk. Examples of risks include exposure to exchange rate risk related to transactions denominated in currencies other than the functional currency, changes in commodity costs and interest rates. It is the objective and responsibility of the Company to assess the impact of these transaction risks and offer protection from selected risks through various methods, including financial derivatives. Virtually all derivative instruments held by the Company are designated as hedges, have high correlation with the underlying exposure and are highly effective in offsetting underlying price movements. Accordingly, gains and losses from changes in qualifying hedge fair values are matched with the underlying transactions. All hedge instruments are carried at their fair value based on quoted market prices for contracts with similar maturities. The Company does not engage in any derivative transactions for purposes other than hedging specific risks.

Refer to Note 11, "Financial Instruments," to the Consolidated Financial Statements for more information.

Foreign currency

Foreign currency The financial statements of foreign subsidiaries are translated to U.S. dollars using the period-end exchange rate for assets and liabilities and an average exchange rate for each period for revenues, expenses and capital expenditures. The local currency is the functional currency for substantially all of the Company's foreign subsidiaries. Translation adjustments for foreign subsidiaries are recorded as a component of accumulated other comprehensive income (loss) in equity. The Company recognizes transaction gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency in earnings as incurred.

Refer to Note 14, "Accumulated Other Comprehensive Income," to the Consolidated Financial Statements for more information.

Pension and other postretirement plans

Pensions and other postretirement employee defined benefits The Company's defined benefit pension and other postretirement employee benefit plans are accounted for in accordance with ASC Topic 715. Disability, early retirement and other postretirement employee benefits are accounted for in accordance with ASC Topic 712.

Pensions and other postretirement employee benefit costs and related liabilities and assets are dependent upon assumptions used in calculating such amounts. These assumptions include discount rates, expected returns on plan assets, health care cost trends, compensation and other factors. In accordance with GAAP, actual results that differ from the assumptions used are accumulated and amortized over future periods, and accordingly, generally affect recognized expense in future periods.

Refer to Note 12, "Retirement Benefit Plans," to the Consolidated Financial Statements for more information.

Restructuring

Restructuring Restructuring costs may occur when the Company takes action to exit or significantly curtail a part of its operations or implements a reorganization that affects the nature and focus of operations. A restructuring charge can consist of severance costs associated with reductions to the workforce, costs to terminate an operating lease or contract, professional fees and other costs incurred related to the implementation of restructuring activities.

Refer to Note 16, "Restructuring," to the Consolidated Financial Statements for more information.

Income taxes

Income taxes In accordance with ASC Topic 740, the Company's income tax expense is calculated based on expected income and statutory tax rates in the various jurisdictions in which the Company operates and requires the use of management's estimates and judgments.

Refer to Note 5, "Income Taxes," to the Consolidated Financial Statements for more information.

New Accounting Pronouncements

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)." It requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance (Subtopic 350-40). This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update ("ASU") No. 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)." The new standard (i) requires the removal of disclosures that are no longer considered cost beneficial; (ii) clarifies specific requirements of certain disclosures; (iii) adds new disclosure requirements, including the weighted average interest crediting rates for cash balance plans and other plans with promised interest crediting rates, and reasons for significant gains and losses related to changes in the benefit obligation. This guidance is effective for annual periods beginning after December 15, 2020 and early adoption is permitted. The Company is currently assessing the guidance and will include enhanced disclosures in the consolidated financial statements upon adoption.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820)." It removes disclosure requirements on fair value measurements including the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. It also amends and clarifies certain disclosures and adds new disclosure requirements including the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This guidance is effective for interim and annual periods beginning after December 15, 2019. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until the effective date. The Company is currently assessing the guidance and does not expect this guidance to have a material impact on its consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-07, "Compensation - Stock Compensation (Topic 718)." It expands the scope of the employee share-based payments guidance, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. This guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect this guidance to have any impact on its Consolidated Financial Statements.

In February 2018, the FASB issued ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)." It allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 ("the Tax Act"). This guidance is effective for interim and annual periods beginning after December 15, 2018, but early adoption is permitted. The Company early adopted this guidance in the fourth quarter of 2018 and recorded a transition adjustment as of January 1, 2018, which increased retained earnings and decreased accumulated other comprehensive income by $14.0 million on its consolidated balance sheet.

In August 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-12, "Derivatives and Hedging (Topic 815)." It expands and refines hedge accounting for both nonfinancial and financial risk components and reduces complexity in fair value hedges of interest rate risk. It eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. It also eases certain documentation and assessment requirements and modifies the accounting for components excluded from assessment of hedge effectiveness. In addition, the new guidance requires expanded disclosures as it pertains to the effect of hedging on individual income statement lines, including the effects of components excluded from the assessment of effectiveness. The guidance is effective prospectively for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company adopted this guidance during the first quarter of 2018 and the impact on the consolidated financial statements was not material. Refer to Note 11, "Financial Instruments," to the Consolidated Financial Statements for more information.

In March 2017, the FASB issued ASU No. 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." It requires disaggregating the service cost component from the other components of net benefit cost, provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization when applicable. This guidance is effective for interim and annual periods beginning after December 15, 2017. During the first quarter of 2018, the Company retrospectively adopted the presentation of service cost separate from the other components of net benefit costs. As a result, Cost of sales of $4.5 million and $4.4 million and Selling, general and administrative expenses of $0.6 million and $0.5 million for the year ended December 31, 2017 and 2016, respectively, have been reclassified to Other postretirement income as a separate line item in the Condensed Consolidated Statements of Operations.

In January 2017, the FASB issued Accounting Standards Update ("ASU") No. 2017-01, "Clarifying the Definition of a Business." It revises the definition of a business and provides a framework to evaluate when an input and a substantive process are present in an acquisition to be considered a business. This guidance is effective for annual periods beginning after December 15, 2017. The Company adopted this guidance in the first quarter of 2018 and there was no impact to the consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, "Restricted Cash." It requires that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The Company adopted this guidance in the first quarter of 2018 and there was no impact to the consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments." It provides guidance on eight specific cash flow issues with the objective of reducing the existing diversity in practice in how they are classified in the statement of cash flows. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The Company adopted this guidance in the first quarter of 2018 and there was no impact to the consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326)." It replaces the current incurred loss impairment method with a new method that reflects expected credit losses. Under this new model an entity would recognize an impairment allowance equal to its current estimate of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Under this guidance, lessees will be required to recognize a right-of-use asset and a lease liability for leases with a term more than 12 months, including operating leases defined under previous GAAP. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018. The Company has elected not to restate comparative periods upon adoption, but record a cumulative-effect adjustment to the opening balance of retained earnings at January 1, 2019. As permitted under the standard, the Company will elect the package of practical expedients, which does not require the Company to reassess whether existing contracts contain leases, classification of leases identified, nor classification and treatment of initial direct costs capitalized under ASC 840. The Company will also elect the practical expedients to combine the lease and non-lease components. The Company will not elect the practical expedient to apply hindsight as part of the leases evaluation. Additionally, the Company will elect the practical expedient under ASU No. 2018-01, which allows an entity to not reassess whether any existing land easements are or contain leases.

The Company has performed an assessment, which included evaluating all forms of leasing arrangements. The majority of the Company’s global lease portfolio represents leases of real estate, such as manufacturing facilities, warehouses, and office buildings, while the remainder represents leases of personal property, such as vehicle leases, manufacturing and IT equipment. Based on the results of the assessment, the Company has refined its internal policy to include criteria for evaluating the impact of the new standard and related controls to support the requirements of this new standard. The Company is currently implementing system solutions as part of the adoption process. The Company is in the process of finalizing its assessment of the impact upon adoption and estimates that the adoption of this guidance will result in the addition of right-of-use assets and corresponding lease obligations to the consolidated balance sheet between $100 million - $120 million. The adoption will not have a material impact to the consolidated statements of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." It requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. It also requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. This guidance is effective for interim and fiscal years beginning after December 15, 2017. The Company adopted this guidance in the first quarter of 2018 with no impact to the consolidated financial statements and elected the measurement alternative for equity investments without readily determinable fair values.

In May 2014, the FASB amended the Accounting Standards Codification to add Topic 606 and issued ASU 2014-09, "Revenue from Contracts with Customers," outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseding the then applicable revenue recognition guidance. The new guidance requires new disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We adopted this new standard and all the related amendments (“new revenue standard”) effective January 1, 2018 and applied it to all contracts using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We expect the impact of adoption of the new standard to be immaterial to our sales and net income on an ongoing basis.

Revenue is recognized when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of our products. For most of our products, transfer of control occurs upon shipment or delivery, however, a limited number of our customer arrangements for our highly customized products with no alternative use provide us with the right to payment during the production process. As a result, for these limited arrangements, under the new revenue standard, revenue is recognized as goods are produced and control transfers to the customer. The Company recorded a transition adjustment as of January 1, 2018, which increased retained earnings by $2.0 million related to these arrangements.

The Company also has a limited number of arrangements with customers where the price paid by the customer is dependent on the volume of product purchased over the term of the arrangement. Under the new revenue standard, the Company estimates the volumes to be sold over the term of the arrangement and recognizes revenue based on the estimated amount of consideration to be received from these arrangements. The Company recorded a transition adjustment, which decreased the opening balance of retained earnings by $0.1 million related to these arrangements.

The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet for the adoption of new revenue standard was as follows:



(In millions)	Balance at December 31, 2017		Adjustments due to ASC 606			Balance at January 1, 2018
Inventories, net	$	766.3	$	(7.4	)	$	758.9
Prepayments and other current assets (including contract assets)	$	145.4	$	9.4		$	154.8
Accounts payable and other accrued expenses (including contract liabilities)	$	2,270.3	$	0.1		$	2,270.4
Retained earnings	$	4,531.0	$	1.9		$	4,532.9

The impact from adopting the new revenue standard as compared to the previous revenue guidance is immaterial to our Consolidated Statements of Operations and Consolidated Balance Sheets for the year ended December 31, 2018.
