Accounting Changes And Error Corrections [Abstract]
Recently Issued Accounting Standards	Note 2 — Recently issued accounting standards New accounting guidance adopted: In April 2015, the Financial Accounting Standards Board (FASB) issued a new standard regarding the presentation of debt issuance costs. Under this standard, a company is required to present unamortized debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of that debt liability, rather than as a separate asset. The recognition and measurement guidance for debt issuance costs are not affected by this new standard. In August 2015, the FASB issued an amendment to this standard, which added clarification to the presentation of debt issuance costs. This amendment allows debt issuance costs related to line-of-credit arrangements to be presented as an asset and subsequently amortized ratably over the term of the line-of-credit agreement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. We adopted this standard during the first quarter of 2017, and applied this standard retrospectively to 2016. The new guidance only impacted presentation on our consolidated balance sheet and did not affect our results of operations or other financial statement disclosures. Refer to Note 10 for the impact on our Consolidated Balance Sheet at October 31, 2016. In May 2015, the FASB issued a new standard regarding the disclosures for investments that calculate net asset value per share (or its equivalent). Under the new guidance, investments measured at net asset value (“NAV”), as a practical expedient for fair value, are excluded from the fair value hierarchy. Removing investments measured using the practical expedient from the fair value hierarchy is intended to eliminate the diversity in practice that currently exists with respect to the categorization of these investments. We adopted this standard in 2017. The new guidance only impacted the presentation of certain pension related assets that use NAV as a practical expedient. Refer to Note 7 for additional information. In October 2016, the FASB issued a new standard which requires companies to recognize in the income statement the income tax effects of intercompany sales or transfer of assets, other than inventory, as income tax expense (or benefit) in the period the sale or transfer occurs. It would have been effective for us beginning in 2019; however, we early adopted this guidance in the first quarter of 2017, and it did not have a material impact on our consolidated financial statements. In January 2017, the FASB issued a new standard which eliminates Step 2 from the goodwill impairment test in order to simplify the subsequent measurement of any goodwill impairment charge. It will be effective for us beginning in 2021. Early adoption is permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017, and the prospective transition method should be applied. We adopted this standard, prospectively, in the fourth quarter of 2017. The adoption did not have an impact on our consolidated financial statements as we did not record any goodwill impairment charges. New accounting guidance issued and not yet adopted: In May 2014, the FASB issued a new standard regarding revenue recognition. Under this standard, a company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard implements a five-step process for customer contract revenue recognition that focuses on transfer of control. In August 2015, the FASB issued a standard to delay the effective date by one year. The new standard is effective for us beginning November 1, 2018. The new standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. We have not yet selected a transition method; however, we are currently anticipating using the modified retrospective method, but will base the final decision on the results of our assessment once complete. Our initial analysis of identifying revenue streams and evaluating a representative sample of contracts and other agreements with our customers is substantially complete. We are in the process of assessing the impact of the new standard, if any, on our business processes, systems and controls. We will finalize our evaluation of potential differences that may result from applying the new standard to our contracts with customers in 2018 and provide updates on our progress in future filings. In February 2016, the FASB issued a new standard which requires a lessee to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases with a lease term of more than twelve months. Leases will continue to be classified as either financing or operating, with classification affecting the recognition, measurement and presentation of expenses and cash flows arising from a lease. It will be effective for us beginning in 2020. We are currently assessing the impact this standard will have on our consolidated financial statements. In March 2016, the FASB issued a new standard which simplifies the accounting for share-based payment transactions. This guidance requires that excess tax benefits and tax deficiencies be recognized as income tax expense or benefit in the income statement rather than additional paid-in capital. Additionally, the excess tax benefits will be classified along with other income tax cash flows as an operating activity, rather than a financing activity, on the statement of cash flows. Further, the update allows an entity to make a policy election to recognize forfeitures as they occur or estimate the number of awards expected to be forfeited. It will be effective for us beginning in 2018 and should be applied prospectively, with certain cumulative effect adjustments. Early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements. In March 2017, the FASB issued a new standard which requires the presentation of the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. All other components of net periodic benefit cost will be presented below operating income. Additionally, only the service cost component will be eligible for capitalization in assets. It will be effective for us beginning in 2019. Early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements.
