New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Guidance	New Accounting Guidance Recently Adopted Accounting Guidance During fiscal year 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standard, which is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The accounting standard became effective for the Company in the first quarter of fiscal year 2019. The Company implemented changes to its processes, policies and internal controls to meet the impact of the new standard and disclosure requirements. Refer to Note 16 – “Revenue” to the Condensed Consolidated Financial Statements for further details. During fiscal year 2016, the FASB issued a new accounting standard to address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. This guidance became effective for the Company in the first quarter of fiscal year 2019, and was applied prospectively by means of a cumulative-effect adjustment to the Consolidated Balance Sheet as of September 1, 2018 to equity investments that existed as of the date of adoption of the standard. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements; however, the impact on future periods will depend on the facts and circumstances of future transactions. During fiscal year 2016, the FASB issued a new accounting standard to address the presentation of certain transactions within the statement of cash flows with the objective of reducing the existing diversity in practice. This standard was adopted on September 1, 2018 on a retrospective basis and resulted in a reclassification of cash flows from operating activities to investing activities in the Company’s Consolidated Statement of Cash Flows for cash receipts related to collections on the deferred purchase price receivable on asset-backed securitization transactions. The increase in cash flow from investing activities and the corresponding decrease to cash flow from operating activities upon adoption of the standard was $96.8 million and $596.1 million for the three months ended November 30, 2018 and 2017, respectively. During fiscal year 2017, the FASB issued a new accounting standard to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The new standard eliminates the exception for an intra-entity transfer of an asset other than inventory and requires an entity to recognize the income tax consequences when the transfer occurs. This guidance became effective for the Company beginning in the first quarter of fiscal year 2019. This guidance was adopted on a modified retrospective basis and an immaterial cumulative-effect adjustment was recorded, which reduced retained earnings as of September 1, 2018. During fiscal year 2017, the FASB issued a new accounting standard which clarifies the scope of accounting for asset derecognition and adds further guidance for recognizing gains and losses from the transfer of non-financial assets in contracts with non-customers. This guidance became effective for the Company beginning in the first quarter of fiscal year 2019 coincident with the new revenue recognition guidance. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements; however, the impact on future periods will depend on the facts and circumstances of future transactions. During fiscal year 2017, the FASB issued a new accounting standard to improve the presentation of net periodic pension benefit cost. The Company adopted the standard on September 1, 2018 on a retrospective basis which results in reclassifications for the service cost component of net periodic benefit cost from selling, general and administrative expense to cost of revenue and for the other components from selling, general and administrative expense to other expense. Prior periods have not been reclassified due to immateriality. During the second quarter of fiscal year 2018, the Securities and Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cut and Jobs Act (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act of 2017 (“Tax Act”). SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The Company has applied SAB 118 and provided required disclosures in Note 15 - “Income Taxes.” Recently Issued Accounting Guidance During fiscal year 2016, the FASB issued a new accounting standard revising lease accounting. The new guidance requires organizations to recognize lease assets and lease liabilities on the Consolidated Balance Sheet and disclose key information regarding leasing arrangements. This guidance is effective for the Company beginning in the first quarter of fiscal year 2020. Early application of the new standard is permitted and the standard must be adopted using a modified retrospective approach. In preparation for the adoption, the Company is implementing a new lease accounting system. The adoption of this standard will impact the Company’s Consolidated Balance Sheet. The Company is currently evaluating practical expedients and accounting policy elections, and assessing overall impacts this new standard will have on its Consolidated Financial Statements. During fiscal year 2016, the FASB issued an accounting standard, which replaces the existing incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This guidance is effective for the Company beginning in the first quarter of fiscal year 2021 and early adoption is permitted beginning in the first quarter of fiscal year 2020. This guidance must be applied using a modified retrospective or prospective transition method, depending on the area covered by this accounting standard. The Company is currently assessing the impact this new standard may have on its Consolidated Financial Statements. During fiscal year 2017, the FASB issued a new accounting standard to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities by simplifying the application of hedge accounting and improving the related disclosures in its financial statements. This guidance is effective for the Company beginning in the first quarter of fiscal year 2020, with early adoption permitted. The guidance must be applied using a modified retrospective approach. The adoption of this standard is not expected to have a material impact on the Company's Consolidated Financial Statements; however, the impact on future periods will depend on the facts and circumstances of future transactions. During fiscal year 2018, the FASB issued a new accounting standard which allows a reclassification from AOCI to retained earnings for stranded tax effects resulting from the Tax Act. This guidance is effective for the Company beginning in the first quarter of fiscal year 2020, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's Consolidated Financial Statements. During fiscal year 2018, the FASB issued a new accounting standard which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance is effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. The Company is currently assessing the impact this new standard may have on its Consolidated Financial Statements. Recently issued accounting guidance not discussed above is not applicable or did not have, or is not expected to have, a material impact to the Company.
