(1)In accordance with regulatory capital rules, the Company elected to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period, which ended on January 1, 2022, and a subsequent three-year transition period, which ended on December 31, 2024. During the three-year transition period, regulatory capital ratios phased out the aggregate amount of the regulatory capital benefit provided from the delayed CECL adoption in the initial two years. For 2024, the Company was allowed 25%, of the regulatory capital benefit as of December 31, 2021. Full absorption occurred in 2025.
