New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted and New Accounting Standards	Recently Adopted and New Accounting Standards Recently Adopted In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income to allow for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (Act). This ASU also requires certain disclosures about stranded tax effects. We adopted this standard on January 1, 2018, which resulted in the reclassification of $12.9 million between retained earnings and accumulated other comprehensive loss (AOCL), increasing retained earnings and AOCL within the equity section of our Consolidated Balance Sheet. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The ASU was effective prospectively for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We adopted this standard on January 1, 2018. The adoption of this ASU did not have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The standard requires that an employer disaggregate the service cost component, presented within the "Cost of sales" and "Selling, general, and administrative" line items on our Consolidated Statements of Operations, from the other components of net periodic cost (benefit), which are now presented within the "Non-operating pension and other postretirement benefit (costs) income" line item in our Consolidated Statements of Operations. We adopted the standard effective January 1, 2018, which resulted in the retrospective presentation in the income statement of the disaggregated components and the prospective changes to the capitalized portion of both service cost and the other components within inventory. The adoption did not have a material impact on our consolidated financial statements. Refer to Note 10, "Pension and Other Postretirement Employee Benefit Plans," for further information, including the amounts associated with the reclassification of the components of net periodic cost as operating and non-operating. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of the new standard is for companies to recognize revenue in a manner that depicts the transfer of goods or services to customers in amounts that reflect the consideration, or payment, to which the company expects to be entitled in exchange for those goods or services. The standard requires enhanced disclosures about revenue, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. We adopted the new revenue guidance effective January 1, 2018 using the cumulative effect method, and did not have an adjustment to retained earnings upon adoption. The standard was applied to open contracts at the date of initial application. Aside from expanded disclosures, the adoption of Topic 606 did not have a material impact on our consolidated financial statement line items, processes, or internal controls. Refer to Note 1, "Nature of Operations and Basis of Presentation," for information about the basis of revenue recognition, and Note 15, "Segment Information," for further information including the disaggregation of revenue by segment, primary geographical market, and major product type. New Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We expect the adoption of this ASU will increase both our assets and liabilities presented on our Consolidated Balance Sheets to reflect the ROU assets and corresponding lease liabilities, as well as increase our leasing disclosures. As of December 31, 2017, the total future minimum lease payments for our operating leases totaled $75.3 million. We plan to adopt this standard on January 1, 2019. We are continuing our assessment and review of existing leases, which may identify other impacts, and are addressing necessary policy and process changes in preparation for adoption. We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable to our business.
