New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted In May 2014, the Financial Accounting Standards Board (FASB) issued revised guidance on the recognition of revenue from contracts with customers. We adopted the guidance in the first quarter of 2019, effective on July 30, 2018, using the modified retrospective method and recorded a cumulative effect adjustment of $8, net of tax, to decrease the opening balance of Earnings retained in the business, an increase of $10 to Accrued liabilities, an increase of $1 to Accounts payable, a decrease of $2 to Deferred taxes and an increase of $1 to Other assets. In February 2016, the FASB issued guidance that amends accounting for leases. Under the new guidance, a lessee will recognize most leases on the balance sheet but will recognize expenses similar to current lease accounting. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. In July 2018, the FASB issued an adoption approach that allows entities to apply the new guidance and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restating prior periods. We adopted the new guidance at the beginning of 2020 using this transition method. We elected to apply a package of practical expedients, which allowed us to not reassess prior conclusions related to contracts containing leases, lease classification, and initial direct costs. Adoption of the new guidance resulted in the recognition of operating lease ROU assets of $259 and operating lease liabilities of $254, with the difference between the assets and liabilities primarily due to below market assets, deferred rent and prepaid rent. In addition, we derecognized $20 of an asset and liability associated with a build-to-suit lease arrangement. The adoption did not have a material impact on consolidated net earnings or cash flows. See Note 11 for additional information. In February 2018, the FASB issued guidance that provides entities an option to reclassify the stranded tax effects of the Tax Cuts and Jobs Act of 2017 on items within accumulated other comprehensive income to retained earnings. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those years. We adopted the guidance in the first quarter of 2019, effective on July 30, 2018, and elected not to reclassify prior periods. The adoption resulted in a cumulative effect adjustment of $9 to decrease the opening balance of Earnings retained in the business and a corresponding net decrease to the components of Accumulated other comprehensive income (loss). See Note 4 for additional information. In August 2017, the FASB issued guidance that amends hedge accounting. Under the new guidance, more hedging strategies will be eligible for hedge accounting and the application of hedge accounting is simplified. The new guidance amends presentation and disclosure requirements, and how effectiveness is assessed. In October 2018, the FASB issued guidance which permits an entity to designate the overnight index swap rate based on the Secured Overnight Financing Rate Fed Funds as a benchmark interest rate in a hedge accounting relationship. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those years. We adopted the new guidance at the beginning of the first quarter of 2020. The adoption did not have a material impact on our consolidated financial statements. Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued guidance that changes the disclosure requirements related to defined benefit pension and postretirement plans. The guidance is effective for fiscal years beginning after December 15, 2020. The guidance is to be applied on a retrospective basis. Early adoption is permitted. We are currently evaluating the impact that the new guidance will have on our disclosures. In August 2018, the FASB issued guidance that eliminates, adds, and modifies certain disclosure requirements for fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted. Certain disclosures in the guidance must be applied on a retrospective basis, while others must be applied on a prospective basis. We are currently evaluating the impact that the new guidance will have on our disclosures. In August 2018, the FASB issued guidance on accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The guidance 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. The guidance is effective for fiscal years beginning after December 15, 2019. Entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively. Early adoption is permitted. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements. We intend to adopt the guidance on a prospective basis. In December 2019, the FASB issued guidance on simplifying the accounting for income taxes. The guidance removes certain exceptions to the general principles of accounting for income taxes and also improves consistent application of accounting by clarifying or amending existing guidance. The guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those years. Early adoption is permitted. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements. In March 2020, the FASB issued guidance that provides optional expedients and exceptions for a limited period of time for accounting for contracts, hedging relationships, and other transactions affected by the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued. Optional expedients can be applied from March 12, 2020 through December 31, 2022. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements.
