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 1, 2022. 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 December 31, 2022 and the results of operations for the three months ended December 31, 2022 and January 1, 2022. 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. Goodwill Goodwill is initially recorded at fair value and not amortized, but is reviewed for impairment at least annually or more frequently if impairment indicators arise. Our goodwill is evaluated for impairment by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary. If it is determined, based on qualitative factors, the fair value of the reporting unit may be more likely than not less than carrying amount, or if significant changes to macro-economic factors related to the reporting unit have occurred that could materially impact fair value, a quantitative goodwill impairment test would be required. The quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of goodwill. During fiscal 2022, we determined that all of our material reporting units’ estimated fair value exceeded their carrying value by more than 20%, other than one of our Chicken segment reporting units and two of our International reporting units with goodwill totaling $0.6 billion and $0.2 billion, respectively, at October 1, 2022. Conditions existed as of the end our first quarter that required an interim assessment of goodwill for two of our International reporting units which had goodwill totaling $0.2 billion at December 31, 2022. Based on the interim assessment, we determined no impairment was necessary as the fair value of the reporting units exceeded their carrying value. Some of the inherent estimates and assumptions used in determining fair value of the reporting units are outside the control of management, including interest rates, cost of capital, tax rates, market EBITDA comparables and credit ratings. While we believe we have made reasonable estimates and assumptions to calculate the fair value of the reporting units, it is possible a material change could occur. If our actual results are not consistent with our estimates and assumptions used to calculate fair value, it could result in additional material impairments of our goodwill. 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. During the first quarter of fiscal 2023, we revised estimates and recorded adjustments of approximately $30 million primarily to reduce certain employee compensation accruals recorded as of October 1, 2022. Recently Issued Accounting Pronouncements In September 2022, the Financial Accounting Standards Board (the "FASB") issued guidance that requires additional disclosures for supplier finance programs to allow users to better understand the nature, activity and potential magnitude of the programs. The guidance, except for a requirement for rollforward information, is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2022, our fiscal 2024. Disclosure of rollforward information is effective for fiscal years after December 15, 2023, our fiscal 2025. Early adoption is permitted and the retrospective transition method should be applied for all amendments except rollforward information, which should be applied prospectively. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In March 2020, the 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 was set to end on December 31, 2022, was extended by new guidance issued by the FASB on December 21, 2022 to apply through December 31, 2024. The temporary accounting relief provided in the optional guidance 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, 2024.
