New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
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 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," which requires entities to present the service cost component of net periodic pension cost and net periodic postretirement benefit cost in the income statement line items where they report compensation cost. Entities will present all other components of net benefit cost outside operating income, if this subtotal is presented. The amendment only impacts where those costs are reflected within the income statement. In addition, only the service cost component of net benefit cost is eligible for capitalization. The Company adopted ASU 2017-07 effective August 1, 2018 and elected the practical expedient to use the components of cost disclosed in prior years as a basis for the retrospective application of the new income statement presentation. The impact of the adoption on the Company's condensed consolidated financial statements was not significant for the three months ended October 31, 2018 and 2017. Refer to Note 4 "Employee Benefit Plans" in our annual report on Form 10-K for the year ended July 31, 2018. 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. This guidance 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, has selected a third-party software program to track and store its leases, and has accumulated data pertaining to its global lease obligations. 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 under current GAAP and replaces 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 insignificant and did not have a material impact on 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.
