Regions and Regions Bank are required to comply with regulatory capital requirements established by Federal and State banking agencies. These regulatory capital requirements involve quantitative measures of the Company’s assets, liabilities and selected off-balance sheet items, and also qualitative judgments by the regulators. Failure to meet minimum capital requirements can subject the Company to a series of increasingly restrictive regulatory actions. Under the Basel III Rules, Regions is designated as a standardized approach bank. Regions is a "Category IV" institution under the Federal Reserve's rules for tailoring enhanced prudential standards.

Banking regulations identify five capital categories: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. At December 31, 2023 and 2022, Regions and Regions Bank exceeded all current regulatory requirements, and were classified as "well-capitalized." Management believes that no events or changes have occurred subsequent to December 31, 2023 that would change this designation.

Quantitative measures established by regulation to ensure capital adequacy require institutions to maintain minimum ratios of common equity Tier 1, Tier 1, and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to average tangible assets (the "Leverage" ratio).

Federal banking agencies allowed a phase-in of the impact of CECL on regulatory capital. At December 31, 2021, the add-back to regulatory capital was calculated as the impact of initial adoption, adjusted for 25 percent of subsequent changes in the allowance. The amount is phased-in over a three-year period beginning in 2022. At December 31, 2023, the net impact of the add-back on CET1 was approximately $204 million or approximately 16 basis points. The add-back amounts will decrease by approximately $100 million each year, or approximately 8 basis points, in the first quarters of 2024 and 2025.

Regions participates in supervisory stress testing conducted by the Federal Reserve and its SCB is currently floored at 2.5 percent. See Note 14 to the consolidated financial statements for further details regarding CCAR results.
