Banking And Thrift Disclosure [Abstract] |
Regulatory Capital Matters | Regulatory Capital Matters The amount of dividends payable to the parent company from the subsidiary bank is limited by various banking regulatory agencies. Upon approval by regulatory authorities, the Bank may pay cash dividends to the parent company in excess of regulatory limitations. As of September 30, 2025, the Company and the Bank were categorized as well-capitalized under the regulatory framework for prompt corrective action in effect at such time. To be categorized as well-capitalized, the Company and the Bank must have exceeded the well-capitalized guideline ratios in effect at the time, as set forth in the tables below, and have met certain other requirements. Management believes that the Company and the Bank exceeded all well-capitalized requirements at September 30, 2025, and there have been no conditions or events since quarter-end that would change the status of well-capitalized. The following tables summarize regulatory capital information as of September 30, 2025 and December 31, 2024 on a consolidated basis and for the subsidiary, as defined. Regulatory capital ratios for September 30, 2025 and December 31, 2024 were calculated in accordance with the Basel III rules.
