(1)In accordance with regulatory capital rules, Webster elected an option to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period ending on January 1, 2022, and subsequent three-year transition period ending on December 31, 2024. As a result, capital ratios and amounts exclude the impact of the increased ACL on loans and leases, held-to-maturity debt securities, and unfunded loan commitments attributed to the adoption of CECL on January 1, 2020, adjusted for an approximation of the after-tax provision for credit losses attributable to CECL relative to the incurred loss methodology during the deferral period.
