Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | NOTE 1. BASIS OF PRESENTATION Regions Financial Corporation (“Regions” or the "Company”) provides a full range of banking and bank-related services to individual and corporate customers through its subsidiaries and branch offices located across the South, Midwest and Texas as well as delivering specialty capabilities nationwide. Regions is subject to the regulations of certain government agencies and undergoes periodic examinations by certain regulatory authorities. The accounting and reporting policies of Regions and the methods of applying those policies that materially affect the consolidated financial statements conform with GAAP and with general financial services industry practices. The accompanying interim financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes to the consolidated financial statements necessary for a complete presentation of financial position, results of operations, comprehensive income (loss) and cash flows in conformity with GAAP. In the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements have been included. These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto in Regions’ Annual Report on Form 10-K for the year ended December 31, 2023. Regions has evaluated all subsequent events for potential recognition and disclosure through the filing date of this Form 10-Q. During 2024, the Company adopted new accounting guidance. See below and Note 13 for related disclosures. BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of Regions, its subsidiaries and certain VIEs. See Note 1 in Regions’ Annual Report on Form 10-K for the year ended December 31, 2023 for additional information about consolidation principals surrounding VIEs. On January 1, 2024, the Company adopted new accounting guidance that allows entities to elect to account for qualifying tax credit investments using the proportional amortization method, on a tax-credit program by tax-credit program basis, if certain conditions are met. Regions adopted the guidance under the modified-retrospective transition approach, with an immaterial cumulative impact recorded to retained earnings. Previously, Regions recognized equity investments in economic development projects at cost, with periodic adjustments for impairment, and applied proportional amortization to investments in affordable housing projects in accordance with other guidance. Refer to Note 2 for additional disclosures.
