Regulatory Capital Framework and Requirements
For a discussion of the Firm’s regulatory capital framework, see Note 16 to the financial statements in the 2023 Form 10-K.
The Firm is required to maintain minimum risk-based and leverage-based capital ratios under regulatory capital requirements. A summary of the calculations of regulatory capital and RWA follows.
Risk-Based Regulatory Capital. Risk-based capital ratio requirements apply to Common Equity Tier 1 (“CET1”) capital, Tier 1 capital and Total capital (which includes Tier 2 capital), each as a percentage of RWA, and consist of regulatory minimum required ratios plus the Firm’s capital buffer requirement. Capital requirements require certain adjustments to, and deductions from, capital for purposes of determining these ratios. At June 30, 2024 and December 31, 2023, the differences between the actual and required ratios were lower under the Standardized Approach.
CECL Deferral. Beginning on January 1, 2020, the Firm elected to defer the effect of the adoption of CECL on its risk-based and leverage-based capital amounts and ratios, as well as RWA, adjusted average assets and supplementary leverage exposure calculations, over a five-year transition period. The deferral impacts began to phase in at 25% per year from January 1, 2022 and are phased-in at 75% from January 1,
2024. The deferral impacts will become fully phased-in beginning on January 1, 2025.

1.The CCyB can be set up to 2.5%, but is currently set by the Federal Reserve at zero.
The capital buffer requirement represents the amount of Common Equity Tier 1 capital the Firm must maintain above the minimum risk-based capital requirements in order to avoid restrictions on the Firm’s ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. The Firm’s capital buffer requirement computed under the standardized approaches for calculating credit risk and market risk RWA (“Standardized Approach”) is equal to the sum of the SCB, G-SIB capital surcharge and CCyB, and the capital buffer requirement computed under the applicable advanced approaches for calculating credit risk, market risk and operational risk RWA (“Advanced Approach”) is equal to the sum of the 2.5% capital conservation buffer, G-SIB capital surcharge and CCyB.

1.Adjusted average assets represents the denominator of the Tier 1 leverage ratio and is composed of the average daily balance of consolidated on-balance sheet assets for the quarters ending on the respective balance sheet dates, reduced by disallowed goodwill, intangible assets, investments in covered funds, defined benefit pension plan assets, after-tax gain on sale from assets sold into securitizations, investments in our own capital instruments, certain deferred tax assets and other capital deductions.
2.Supplementary leverage exposure is the sum of Adjusted average assets used in the Tier 1 leverage ratio and other adjustments, primarily: (i) for derivatives, potential future exposure and the effective notional principal amount of sold credit protection offset by qualifying purchased credit protection; (ii) the counterparty credit risk for repo-style transactions; and (iii) the credit equivalent amount for off-balance sheet exposures.
3.Required ratios are inclusive of any buffers applicable as of the date presented.
U.S. Bank Subsidiaries’ Regulatory Capital and Capital Ratios
The OCC establishes capital requirements for the U.S. Bank Subsidiaries, and evaluates their compliance with such capital requirements. Regulatory capital requirements for the U.S. Bank Subsidiaries are calculated in a similar manner to the Firm’s regulatory capital requirements, although G-SIB capital surcharge and SCB requirements do not apply to the U.S. Bank Subsidiaries.
The OCC’s regulatory capital framework includes Prompt Corrective Action (“PCA”) standards, including “well-capitalized” PCA standards that are based on specified regulatory capital ratio minimums. For the Firm to remain an FHC, its U.S. Bank Subsidiaries must remain well-capitalized in accordance with the OCC’s PCA standards. In addition,
failure by the U.S. Bank Subsidiaries to meet minimum capital requirements may result in certain mandatory and discretionary actions by regulators that, if undertaken, could have a direct material effect on the U.S. Bank Subsidiaries’ and the Firm’s financial statements.
At June 30, 2024 and December 31, 2023, MSBNA and MSPBNA risk-based capital ratios are based on the Standardized Approach rules. Beginning on January 1, 2020, MSBNA and MSPBNA elected to defer the effect of the adoption of CECL on risk-based capital amounts and ratios, as well as RWA, adjusted average assets and supplementary leverage exposure calculations, over a five-year transition period. The deferral impacts began to phase in at 25% per year from January 1, 2022 and are phased-in at 75% from January 1, 2024. The deferral impacts will become fully phased-in beginning on January 1, 2025.

1.Required ratios are inclusive of any buffers applicable as of the date presented. Failure to maintain the buffers would result in restrictions on the ability to make capital distributions, including the payment of dividends.
Additionally, MSBNA is conditionally registered with the SEC as a security-based swap dealer and is registered with the CFTC as a swap dealer. However, as MSBNA is prudentially regulated as a bank, its capital requirements continue to be determined by the OCC.
