Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements have been prepared in accordance with accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the condensed consolidated financial statements do not include all information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. The information herein reflects all normal recurring material adjustments, which are, in the opinion of management, necessary for the fair statement of the results for the periods presented. The condensed consolidated financial statements herein consist of all wholly-owned domestic and foreign subsidiaries with all significant intercompany transactions eliminated. These condensed consolidated financial statements present the financial position, results of comprehensive income and cash flows of the Company. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2017 as filed with the Securities and Exchange Commission (“SEC”) on February 15, 2018. The interim period financial results for the three and nine month periods presented are not necessarily indicative of results to be expected for any other interim period or for the entire year. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. Estimates include, but are not limited to, sales allowances, government price adjustments, fair market values and future cash flows associated with goodwill, indefinite life intangibles, long-lived asset impairment tests, useful lives for depreciation and amortization, warranty liabilities, environmental liabilities, determination of discount and other assumptions for pension and other post-retirement benefit expense, income taxes and deferred tax valuation allowances, derivative valuation and contingencies. The Company’s accounting policies involve the application of judgments and assumptions made by management that include inherent risks and uncertainties. Actual results could differ materially from these estimates. Changes in estimates are recorded in results of operations in the period that the events or circumstances giving rise to such changes occur. Recently Adopted Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (“FASB”) issued authoritative accounting guidance on accounting for derivative and hedge instruments. Among other things, the guidance allows the initial hedge effectiveness assessment to be performed by the end of the quarter in which the hedge is designated, permits a qualitative assessment for certain hedges if an expectation of high effectiveness can be supported throughout the term of the hedge, and removes the requirement to record ineffectiveness on cash flow hedges immediately through earnings when the hedge is highly effective. The guidance was early adopted by the Company effective April 1, 2018 and applied upon entering into interest rate swaps designated as cash flow hedges during the second quarter of 2018. When adopted in an interim period, the guidance is required to be reflected as of the beginning of the year of adoption. The Company has not previously designated any derivative instruments as hedging instruments, and thus, the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In May 2017, the FASB issued authoritative accounting guidance on accounting for modifications to the terms of employee stock compensation. The guidance clarifies which changes to terms or conditions of share-based payment awards require the entity to apply modification accounting. The guidance was adopted by the Company effective January 1, 2018 and did not have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued authoritative accounting guidance on the presentation of net periodic pension costs and net periodic post-retirement benefit costs. The guidance clarifies the presentation of component costs within an employer’s financial statements and restricts component costs eligible for capitalization to the service cost component. The guidance was adopted by the Company effective January 1, 2018 and did not have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued authoritative accounting guidance on the presentation and classification of certain cash receipts and cash payments on the statement of cash flows. The guidance specifically addresses cash flow issues with the objective of reducing the diversity in practice. The guidance was adopted by the Company effective January 1, 2018 and did not have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued authoritative accounting guidance on a company’s accounting for revenue from contracts with customers, which guidance was subsequently amended. The guidance applies to all companies that enter into contracts with customers to transfer goods, services or nonfinancial assets. The guidance requires these companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires disclosures regarding the nature, timing, amount and uncertainty of revenue that is recognized. The guidance was adopted by the Company effective January 1, 2018 on a modified retrospective basis. See Note C, “Revenue” for information regarding the impact of the adoption of this guidance. Recently Issued Accounting Pronouncements In August 2018, the FASB issued authoritative accounting guidance on accounting for implementation costs in hosting arrangements to align these costs with existing guidance for internally developed software. The stage of implementation must be assessed to determine if costs should be capitalized or expensed, and capitalized costs should be expensed during the noncancellable term of the agreement. The guidance will be effective for the Company in fiscal year 2020, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company's consolidated financial statements. In August 2018, the FASB issued authoritative accounting guidance amending disclosure requirements for the Company's defined benefit pension plans and other postretirement benefit plan. The guidance will be effective for the Company in fiscal year 2021, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company's consolidated financial statements. In August 2018, the FASB issued authoritative accounting guidance amending disclosure requirements for certain assets subject to fair value measurement. The guidance allows the Company to reduce the amount of disclosure on transfers between Level 1 and Level 2 assets. The guidance will be effective for the Company in fiscal year 2020, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company's consolidated financial statements. In June 2018, the FASB issued authoritative accounting guidance on accounting for nonemployee awards for goods or services received by a company. The guidance will be effective for the Company in fiscal year 2019, and the Company does not plan to early adopt. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In February 2018, the FASB issued authoritative accounting guidance on transfers of stranded balances in accumulated other comprehensive loss to retained earnings. The passage of the U.S. Tax Cuts and Jobs Act by the U.S. federal government in December 2017 and existing GAAP requirements to adjust deferred tax assets and liabilities for changes in tax laws or rates created stranded balances in accumulated other comprehensive loss on deferred tax assets and liabilities previously recorded as a component to accumulated other comprehensive loss. The guidance applies to companies affected by these stranded balances and allows a reclassification of these balances to retained earnings. The guidance will be effective for the Company in fiscal year 2019, but early adoption is permitted. The guidance can be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the U.S. Tax Cuts and Jobs Act is recognized. Management is currently evaluating the adoption method the Company will implement; however, Management does not expect the adoption of this guidance to have a material impact on the Company's consolidated financial statements under either adoption method. In February 2016, the FASB issued authoritative accounting guidance on lease accounting. The guidance requires lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases not considered short-term leases. Short-term leases are leases with a lease term of 12 months or less as long as the leases do not include options to purchase the underlying assets that the lessee is reasonably certain to exercise. The guidance also introduces new disclosure requirements for leasing arrangements. The guidance will be effective for the Company in fiscal year 2019 and the Company does not plan to early adopt. In July 2018, the FASB issued additional authoritative guidance on this topic giving lessees an optional adoption approach under which the impact of the adoption of the guidance would be shown as of the date of adoption. Management has elected to adopt the guidance using this modified retrospective approach. Management is currently evaluating the Company’s lease contracts, assessing the impact of the adoption of policy elections and practical expedients prescribed by the guidance and evaluating qualitative information relevant to new disclosure requirements. Management does not expect the adoption of this guidance to have a material impact on the Company’s consolidated financial statements.
