New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Developments	NOTE 2 RECENT ACCOUNTING DEVELOPMENTS Other than as described below, no new accounting pronouncement issued or effective during the fiscal year has had or is expected to have a material impact on the consolidated financial statements. COMPREHENSIVE INCOME In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This guidance gives entities the option to reclassify stranded tax effects caused by the newly-enacted U.S. Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. This guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. The Company is currently evaluating the provisions of this guidance. DERIVATIVES AND HEDGING In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The objective of this new guidance is the improvement of the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. In addition to that main objective, the amendments in this guidance make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted. The Company early adopted the provisions of this guidance effective January 1, 2018, with no material impact on the financial statements. RETIREMENT BENEFITS In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Costs and Net Periodic Postretirement Benefit Cost." Under this new guidance, employers will present the service costs component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components separately from the Line item(s) that includes the service cost and outside of any subtotal of operating income. In addition, disclosure of the Line(s) used to present the other components of net periodic benefit cost will be required if the components are not presented separately in the income statement. This guidance is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted as of the beginning of an annual period for which financial statement (interim or annual) have not been issued or made available for issuance. The Company adopted the provisions of the guidance on January 1, 2018, using the retrospective method. The adoption resulted in a change in our adjusted operating profit (used to measure the earnings performance of the Company's business segments), which is offset by a corresponding change in non-operating pension expense to reflect the impact of presenting the amortization of the prior service cost component of net periodic pension expense outside of operating income. This guidance had no impact on our statements of financial position or cash flows. INTANGIBLES In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This guidance eliminates the requirement to calculate the implied fair value of goodwill under Step 2 of today's goodwill impairment test to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. This guidance should be applied prospectively and is effective for annual reporting periods beginning after December 15, 2019, for any impairment test performed in 2020. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is currently evaluating the provisions of this guidance; however, we do not anticipate adoption having a material impact on the financial statements. INCOME TAXES In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." This ASU requires companies to recognize the income tax effects of intercompany sales and transfers of assets other than inventory in the period in which the transfer occurs rather than defer the income tax effects which is current practice. This new guidance is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years. The guidance requires companies to apply a modified retrospective approach with a cumulative catch-up adjustment to opening retained earnings in the period of adoption. Early adoption is permitted. The Company does not expect that the adoption of this standard will result in a material impact on the financial statements. STOCK COMPENSATION In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): "Scope of Modification Accounting." This guidance clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under this guidance, entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. This guidance is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted, including in any interim period. The Company adopted the provisions of this guidance on January 1, 2018, with no material impact on the financial statements. LEASES In February 2016, the FASB issued ASU 2016-02, Leases Topic (842): "Leases." This ASU will require most leases to be recognized on the balance sheet which will increase reported assets and liabilities. Lessor accounting will remain substantially similar to current U.S. GAAP. This ASU is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years, and mandates a modified retrospective transition method for all entities. The Company expects to adopt this guidance using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We expect to recognize a liability and corresponding asset associated with in-scope operating and finance leases but we are still in the process of determining those amounts and the processes required to account for leasing activity on an ongoing basis. BUSINESS COMBINATIONS In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805) - Clarifying the Definition of a Business." Under the new guidance, an entity must first determine whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of transferred assets and activities is not a business. If this threshold is not met, the entity then evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. This guidance is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted. The Company adopted the provisions of this guidance on January 1, 2018 with no material impact on the financial statements. REVENUE RECOGNITION In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This guidance replaces most existing revenue recognition guidance and provides that an entity should 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 and services. This ASU was effective for annual reporting periods beginning after December 15, 2016, and interim periods within those years and permits the use of either the retrospective or cumulative effect transition method; however, in August 2015, the FASB issued ASU 2015-14 which defers the effective date by one year making the guidance effective for annual reporting periods beginning after December 15, 2017. The FASB has continued to clarify this guidance in various updates during 2015 and 2016, all of which, have the same effective date as the original guidance. We have evaluated the impact of ASU 2014-09 and all related ASUs on our consolidated financial statements. The Company's transition team, including representatives from all of our business segments, has finalized its review and analysis of the impact of the standard on our revenue contracts. Surveys were developed and reviews of customer contracts were performed in order to gather information and identify areas of the Company's business where potential differences could result in applying the requirements of the new standard to its revenue contracts. The results of the surveys, contract reviews and legal analysis indicate that the adoption of the standard will require acceleration of revenue for products produced by the Company without an alternative future use and where the Company has a legally enforceable right of payment for production of products completed to date. The Company adopted the new revenue guidance effective January 1, 2018, using the modified retrospective transition method. Due to the repetitive nature of our sales, we do not expect the impact of this acceleration to significantly alter our reported sales over time. In addition, we do not expect the net impact of adoption to have a material impact on our consolidated results.

Other than as described below, no new accounting pronouncement issued or effective during the fiscal year has had or is expected to have a material impact on the consolidated financial statements.

We have evaluated the impact of ASU 2014-09 and all related ASUs on our consolidated financial statements. The Company's transition team, including representatives from all of our business segments, has finalized its review and analysis of the impact of the standard on our revenue contracts. Surveys were developed and reviews of customer contracts were performed in order to gather information and identify areas of the Company's business where potential differences could result in applying the requirements of the new standard to its revenue contracts. The results of the surveys, contract reviews and legal analysis indicate that the adoption of the standard will require acceleration of revenue for products produced by the Company without an alternative future use and where the Company has a legally enforceable right of payment for production of products completed to date.

Due to the repetitive nature of our sales, we do not expect the impact of this acceleration to significantly alter our reported sales over time. In addition, we do not expect the net impact of adoption to have a material impact on our consolidated results.
