New Accounting Pronouncements [Abstract]
Derivatives [Policy Text Block]	In the first quarter of fiscal 2020, we adopted new accounting requirements for hedge accounting. The new standard amends the hedge accounting recognition and presentation requirements to better align an entity’s risk management activities and financial reporting. The new standard also simplifies the application of hedge accounting guidance. The adoption did not have a material impact on our results of operations or financial position.
Lessee Leases [Policy Text Block]	In the first quarter of fiscal 2020, we adopted new requirements for the accounting, presentation, and classification of leases. This results in certain leases being capitalized as a right of use asset with a related liability on our Consolidated Balance Sheet. We performed a review of our lease portfolio, implemented lease accounting software, and developed a centralized business process with corresponding controls. We adopted this guidance utilizing the cumulative effect adjustment approach, which required application of the guidance at the adoption date, and elected certain practical expedients permitted under the transition guidance, including not reassessing whether existing contracts contain leases and carrying forward the historical classification of those leases. In addition, we elected not to recognize leases with an initial term of 12 months or less on our Consolidated Balance Sheet and to continue our historical treatment of land easements, under permitted elections. This guidance did not have a material impact on retained earnings, our Consolidated Statements of Earnings, or our Consolidated Statements of Cash Flows. See Note 6 to the Consolidated Financial Statements for additional information on the impact to our Consolidated Balance Sheets.
