New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Guidance	NEW ACCOUNTING GUIDANCE Accounting Guidance Implemented in Fiscal Year 2019 Revenue Recognition In May 2014, the Financial Accounting Standards Board (FASB) issued the new revenue standard, which is based on the principle that revenue is recognized in an amount expected to be collected and to which the entity expects to be entitled in exchange for the transfer of goods or services. We adopted this guidance under the modified retrospective approach as of 1 October 2018. Upon adoption, we no longer present "Contracts in progress, less progress billings" on our consolidated balance sheets and have expanded disclosure requirements. Otherwise, adoption of this guidance did not impact our consolidated financial statements, and no adjustment was necessary to opening retained earnings. Accordingly, sales presented during the first quarter of fiscal year 2019 would not change if presented under accounting standards in effect prior to 1 October 2018. For additional information, including the balance sheet impacts of no longer presenting "Contracts in progress, less progress billings" and expanded disclosures under the new revenue standard, refer to Note 3, Revenue Recognition. Cash Flow Statement Classification In August 2016, the FASB issued guidance to reduce diversity in practice related to the classification of certain cash receipts and cash payments in the statement of cash flows. We adopted this guidance retrospectively in the first quarter of fiscal year 2019 and elected to use the cumulative earnings approach to determine the classification of distributions received from equity affiliates. As a result, we reclassified $4.1 of net activity from operating activities to investing activities for the three months ended 31 December 2017. Intra-Entity Asset Transfers In October 2016, the FASB issued guidance on accounting for the income tax effects of intra-entity transfers of assets other than inventory. Previous guidance prohibited the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset had been sold to an outside party. Under the new guidance, the income tax consequences of an intra-entity asset transfer are recognized when the transfer occurs. We adopted this guidance in the first quarter of fiscal year 2019 on a modified retrospective basis through a cumulative-effect adjustment of $17.1 that decreased retained earnings as of 1 October 2018. New Accounting Guidance to be Implemented Leases In February 2016, the FASB issued guidance that requires lessees to recognize a right-of-use asset and lease liability on the balance sheet for all leases, including operating leases, with a term in excess of 12 months. The guidance also expands the quantitative and qualitative disclosure requirements. The Company is the lessee under various agreements for real estate, distribution equipment, aircraft, and vehicles that are currently accounted for as operating leases. The new guidance will require the Company to record all leases, including operating leases, on the balance sheet with a right-of-use asset and corresponding liability for future payment obligations. We will adopt this guidance in fiscal year 2020. The guidance must be applied using a modified retrospective approach with the option to apply the guidance either at the adoption date or at the earliest comparative period presented in the consolidated financial statements. We are evaluating the impact the guidance will have on our consolidated financial statements, including the assessment of our current lease population under the revised definition of what qualifies as a leased asset. In addition, we are implementing a new application to administer the accounting and disclosure requirements under the new guidance. Credit Losses on Financial Instruments In June 2016, the FASB issued guidance on the measurement of credit losses, which requires measurement and recognition of expected credit losses for financial assets, including trade receivables and capital lease receivables, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The method to determine a loss is different from the existing guidance, which requires a credit loss to be recognized when it is probable. The guidance is effective beginning in fiscal year 2021, with early adoption permitted beginning in fiscal year 2020. We are evaluating the impact this guidance will have on our consolidated financial statements. Hedging Activities In August 2017, the FASB issued guidance on hedging activities to expand the related presentation and disclosure requirements, change how companies assess effectiveness, and eliminate the separate measurement and reporting of hedge ineffectiveness. The guidance also enables more financial and nonfinancial hedging strategies to become eligible for hedge accounting. The guidance is effective in fiscal year 2020, with early adoption permitted. For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment to eliminate the separate measurement of ineffectiveness within equity as of the beginning of the fiscal year the guidance is adopted. The amended presentation and disclosure guidance is applied prospectively. We are evaluating the impact this guidance will have on our consolidated financial statements. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued guidance allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act. The guidance is effective in fiscal year 2020, with early adoption permitted, including adoption in an interim period. If elected, the reclassification can be applied in either the period of adoption or retrospectively to the period of the enactment of the U.S. Tax Cuts and Jobs Act (i.e., our first quarter of fiscal year 2018). We are evaluating the adoption alternatives and the impact this guidance will have on our consolidated financial statements. Fair Value Measurement Disclosures In August 2018, the FASB issued guidance that modifies the disclosure requirements for fair value measurements. The guidance is effective in fiscal year 2021, with early adoption permitted. Certain amendments must be applied prospectively while other amendments must be applied retrospectively. We are evaluating the impact this guidance will have on the disclosures in the notes to our consolidated financial statements. Retirement Benefit Disclosures In August 2018, the FASB issued guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement benefit plans. The guidance is effective in fiscal year 2021, with early adoption permitted, and must be applied on a retrospective basis. We are evaluating the impact this guidance will have on the disclosures in the notes to our consolidated financial statements. Cloud Computing Implementation Costs In August 2018, the FASB issued guidance that aligns the capitalization requirements for implementation costs incurred in a hosting arrangement that is a service contract with the existing capitalization requirements for implementation costs incurred to develop or obtain internal-use software. The guidance is effective in fiscal year 2021, with early adoption permitted, and may be applied either prospectively or retrospectively. We are evaluating the impact this guidance will have on our consolidated financial statements. Related Party Guidance for Variable Interest Entities In October 2018, the FASB issued an update that amends the guidance for determining whether a decision-making fee is a variable interest. The amendments require consideration of indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety as required under current accounting standards. The guidance is effective in fiscal year 2021, with early adoption permitted. The amendments must be applied retrospectively with a cumulative-effect adjustment to retained earnings at the beginning of the earliest period presented. We are evaluating the impact this guidance will have on our consolidated financial statements.

Otherwise, adoption of this guidance did not impact our consolidated financial statements, and no adjustment was necessary to opening retained earnings. Accordingly, sales presented during the first quarter of fiscal year 2019 would not change if presented under accounting standards in effect prior to 1 October 2018.
