Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS Effective June 1, 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” and all the related amendments included within Accounting Standards Codification 606 (“ASC 606”), using the modified retrospective method of adoption. Under the modified retrospective method, comparative periods are not restated. The new standard requires an entity to recognize revenue when it transfers 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. This update creates a five-step model that requires entities to exercise judgment when considering the terms of contract(s), which includes (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. As a result of our adoption procedures, we determined that revenue recognition for our broad portfolio of products and services will remain largely unchanged. Accordingly, our adoption of the new standard did not have a material impact on our overall Consolidated Financial Statements. Refer to Note 15, “Revenue,” and Note 16, “Segment Information,” for additional information. In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” which provides amended guidance for certain aspects of recognition, measurement and disclosure of financial instruments. The main provisions of the standard impact how we account for changes in the fair value of our marketable securities currently classified as available-for-sale. Unrealized gains and losses on available-for-sale equity securities are required to be recognized in earnings rather than in other comprehensive income. Our adoption of the new standard during fiscal 2019 did not have a material effect on our overall Consolidated Financial Statements. See Note 4, “Marketable Securities,” and Note 7, “Investment Expense (Income), Net,” for additional information. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which increases lease transparency and comparability among organizations. Under the new standard, lessees will be required to recognize all assets and liabilities arising from leases on the balance sheet, with the exception of leases with a term of 12 months or less, which permits a lessee to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted. In March 2018, the FASB approved an alternative transition method to the modified retrospective approach, which eliminates the requirement to restate prior period financial statements and requires the cumulative effect of the retrospective allocation to be recorded as an adjustment to the opening balance of retained earnings at the date of adoption. We have selected the alternative transition method for adoption, which we will adopt on June 1, 2019 and are still evaluating the impact this guidance will have on our Consolidated Financial Statements. At a minimum, total assets and total liabilities will increase in the period the ASU is adopted. In August 2018, the SEC issued Final Rule Release No. 33-10532, “Disclosure Update and Simplification,” which makes a number of changes meant to simplify interim disclosures. The new rule requires a presentation of changes in stockholders’ equity and noncontrolling interest in the form of a reconciliation, either as a separate financial statement or in the notes to the financial statements, for the current and comparative year-to-date interim periods. The additional elements of this release did not have a material impact on our overall Consolidated Financial Statements. We adopted the new disclosure requirements in our Form 10-Q for the period ended February 28, 2019. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which makes a number of changes meant to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. Our June 1, 2018 adoption of the new guidance, which we applied retrospectively to all periods presented, did not have a material impact on our Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-01, “Business Combinations: Clarifying the Definition of a Business,” with the objective of adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (disposals) of assets or of businesses. We adopted the new guidance as of June 1, 2018 and do not expect this revised guidance to have a material impact on our Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate step two from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Adoption of this guidance is not expected to have a material impact on our Consolidated Financial Statements. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Our June 1, 2018 adoption of the new guidance did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820), – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the update. We do not expect our adoption of this guidance to have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20), Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with employers that sponsor defined benefit or other postretirement plans. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted for all entities and the amendments in this update are required to be applied on a retrospective basis to all periods presented. We are currently reviewing, but adoption of this guidance is not expected to have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, “Intangible—Goodwill and Other- Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The update makes a number of changes meant to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement), by providing guidance in determining when the arrangement includes a software license. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Our early adoption of this revised guidance as of June 1, 2018 did not have a material impact on our Consolidated Financial Statements.
