New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted In May 2014, the Financial Accounting Standards Board (FASB) issued amended revenue recognition guidance to clarify the principles for recognizing revenue from contracts with customers. The guidance requires an entity to recognize revenue in an amount that reflects the consideration to which an entity expects to be entitled in exchange for the transfer of goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The Company adopted this guidance using the modified retrospective method in the first quarter of fiscal year 2019, and elected to apply the guidance only to contracts that were not completed as of the date of initial application. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. In January 2016, the FASB issued guidance which requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The guidance also includes a simplified impairment assessment of equity investments without readily determinable fair values and presentation and disclosure changes. The Company adopted this guidance in the first quarter of fiscal year 2019 on a prospective basis. As a result of the adoption, the Company reclassified $47 million from accumulated other comprehensive loss to the opening balance of retained earnings as of April 28, 2018. In March 2017, the FASB issued guidance which changes the financial statement presentation requirements for pension and other postretirement benefit expense. While service cost will continue to be recognized in the same financial statement line items as other current employee compensation costs, the guidance requires all other non-service components of net benefit costs to be classified and presented outside of income from operations. The Company adopted this guidance in the first quarter of fiscal year 2019, and the consolidated statements of income were retrospectively adjusted. For the three and six months ended October 27, 2017, the Company reclassified $7 million and $14 million, respectively, of income from non-service components of net periodic benefit costs, which were previously presented as a component of operating profit, to other non-operating income, net. In August 2018, the SEC adopted a final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, that amends certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. The amendments also expanded the disclosure requirements on the analysis of shareholders' equity for interim financial statements, in which registrants must now analyze changes in shareholders’ equity, in the form of reconciliation, for the current and comparative year-to-date periods, with subtotals for each interim period. This final rule was effective on November 5, 2018. The Company has adopted all relevant disclosure requirements, with the exception of the shareholders’ equity interim disclosures, which is allowed to be adopted in a future interim period. Not Yet Adopted In February 2016, the FASB issued guidance which requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet. The guidance will be adopted using the modified retrospective method by applying the new guidance as of the transition date with a cumulative-effect adjustment to the opening balance of retained earnings. The guidance is effective for the Company beginning in the first quarter of fiscal year 2020. The Company is evaluating the impact of the lease guidance on the Company's consolidated financial statements and anticipates recording additional assets and corresponding liabilities on its consolidated balance sheets related to operating leases within its lease portfolio upon adoption of the guidance.
