Accounting Policies	ACCOUNTING POLICIES Basis of Presentation The consolidated condensed financial statements are unaudited and have been prepared by Tyson Foods, Inc. (“Tyson,” “the Company,” “we,” “us” or “our”). Certain information and accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Although we believe the disclosures contained herein are adequate to make the information presented not misleading, these consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended October 2, 2021. Preparation of consolidated condensed financial statements requires us to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated condensed financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We believe the accompanying consolidated condensed financial statements contain all adjustments, which are of a normal recurring nature, necessary to state fairly our financial position as of April 2, 2022, and the results of operations for the three and six months ended April 2, 2022, and April 3, 2021. Results of operations and cash flows for the periods presented are not necessarily indicative of results to be expected for the full year. Consolidation The consolidated condensed financial statements include the accounts of all wholly-owned subsidiaries, as well as majority-owned subsidiaries over which we exercise control and, when applicable, entities for which we have a controlling financial interest or variable interest entities for which we are the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The consolidated condensed financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require us to make estimates and assumptions that affect the amounts reported in the consolidated condensed financial statements and accompanying notes. Actual results could differ from those estimates. Risks and Uncertainties We have considered the impact of the global novel coronavirus pandemic (“COVID-19” or “pandemic”) on our consolidated condensed financial statements. In addition to the COVID-19 impacts already experienced, there likely will be future impacts, the extent of which is uncertain and largely subject to whether the severity worsens or duration lengthens. Consequently, this may subject us to future risk of material goodwill, intangible and long-lived asset impairments, increased reserves for uncollectible accounts and adjustments for inventory and market volatility for items subject to fair value measurements such as derivatives and investments. There have been no material changes to the summary of certain accounting estimates, the description of the estimates and the levels of subjectivity and judgment they require found in our Annual Report on Form 10-K for the fiscal year ended October 2, 2021. Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board ("FASB") issued guidance providing optional expedients and exceptions to account for the effects of reference rate reform to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. The optional guidance, which became effective on March 12, 2020 and can be applied through December 31, 2022, has not impacted our consolidated financial statements. The Company has various contracts that reference LIBOR and is assessing how this standard may be applied to specific contract modifications through December 31, 2022. Changes in Accounting Principles In August 2020, the FASB issued guidance that simplifies the accounting for debt with conversion options, revises the criteria for applying the derivative scope exception for contracts in an entity’s own equity and improves the consistency for the calculation of earnings per share. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2021, our fiscal 2023. Early adoption is permitted for annual periods and interim periods within those annual periods beginning after December 15, 2020, our fiscal 2022. We elected to early adopt this guidance beginning in the first quarter of fiscal 2022 and it did not have an impact on our consolidated financial statements. In December 2019, the FASB issued guidance that simplifies the accounting for income taxes by removing certain exceptions to general principles in Topic 740 and clarifies other general principles by adding certain requirements to Topic 740. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2020, our fiscal 2022. We adopted this guidance in the first quarter of fiscal 2022 and it did not have an impact on our consolidated financial statements.
