New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In August 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-12 "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which simplifies and reduces the complexity of the hedge accounting requirements and better aligns an entity's financial reporting for hedging relationships with its risk management activities. The guidance is effective for interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. This new guidance will require a modified retrospective adoption approach to existing hedging relationships as of the adoption date. The Company is currently evaluating the impact of this update on its consolidated financial statements and disclosures. In January 2017, the FASB issued ASU 2017-04, "Goodwill and Other, Simplifying the Test for Goodwill Impairment," which simplifies the accounting for goodwill impairment. The new guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. This guidance is effective for annual periods beginning after December 15, 2019, and interim periods thereafter; however, early adoption is permitted for any impairment tests performed after January 1, 2017. The Company has not adopted this guidance, which will only impact the Company's consolidated financial statements if there is a future impairment of goodwill. In February 2016, the FASB issued ASU 2016-02, "Leases," which replaces the current lease accounting standards. The update requires, among other items, lessees to recognize the assets and liabilities that arise from most leases on the balance sheet. This guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The ASU allows for either a full retrospective or a modified retrospective approach and early adoption is permitted. The Company expects the new lease standard to increase its total assets and liabilities; however, it is evaluating the magnitude of the impact on its consolidated financial statements. The Company has formed a team to implement the new lease standard, implemented a third-party software program to track and store its leases, has accumulated data pertaining to its global lease obligations, and is currently evaluating the impact of this update on its consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("Topic 606"), which eliminates the transaction and industry-specific revenue recognition guidance and replaced it with a principles-based approach for determining revenue recognition. The new guidance requires revenue recognition when control of the goods or services transfers to the customer, replacing the existing guidance which requires revenue recognition when the risks and rewards transfer to the customer. The Company adopted ASU 2014-09 (and related updates) effective August 1, 2018 using the modified retrospective method to apply this guidance to all contracts at the date of initial application. Results for reporting periods beginning after August 1, 2018 are presented under Topic 606, while comparative prior period amounts have not been restated and continue to be presented under accounting standards in effect in those periods. The results of applying Topic 606 were not material to the Company's consolidated financial condition, results of operations, cash flows, business processes, controls, or systems. Upon adoption, the Company recorded a cumulative adjustment to the opening balance of retained earnings as of August 1, 2018, which resulted in a decrease to retained earnings of $2,137, net of tax. The adjustment was primarily due to a change in timing of when revenue and the related costs for certain extended service-type warranties are recognized, as required per Topic 606. Refer to Note C "Revenue Recognition" for additional information and required disclosures under the new standard.
