Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract] |
Minimum Capital Requirements | Minimum capital requirements Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Under regulatory guidance for non-advanced approach institutions, the Bank and Company are required to maintain minimum capital ratios as outlined in the table below. Minimum risk-based capital adequacy ratios below include a capital conservation buffer of 2.50%. As of September 30, 2024 and December 31, 2023, the Bank and Company met all capital adequacy requirements to which they are subject. Additionally, under U.S. Basel III Capital Rules, the Bank and Company opted out of including accumulated other comprehensive income in regulatory capital. The Company elected to phase-in the impact related to adopting ASU 2016-13 over the permissible five-year transition relief period and delayed the initial impact of CECL adoption plus 25% of the quarterly increases in ACL in the first two years after adoption. Beginning in 2022, the cumulative amount of the transition adjustments became fixed and were phased out in annual increments over a three-year period. 2024 represents the final year of this CECL adoption phase out, with 25% of the initial impact of CECL adoption being adjusted out of regulatory capital calculations. Actual and required capital amounts and ratios are included below as of the dates indicated.
