Allowance for credit lossesDescription of the MatterThe Company’s loan portfolio totaled $24.1 billion as of December 31, 2024, and the associated allowance for credit losses (ACL) was $332 million. An $18 million provision for credit losses was recorded for the year ended December 31, 2024. As discussed in Note 1 and 4 to the consolidated financial statements, management’s estimate for the expected credit losses within the loan portfolio represents the portion of amortized cost basis of loans and related unfunded commitments they do not expect to collect over the asset’s contractual life, considering past events, current conditions, as well as reasonable and supportable forecasts of future economic conditions. The allowance for credit losses consists of specific allowances attributed to certain individual loans, generally non-accruing loans, with dissimilar risk characteristics that have not yet been charged down to amounts they expect to recover, general allowances for estimated credit losses on pools of loans that share similar risk characteristics, and qualitative reserves with the estimated impact of factors that are not captured in the modeled results or historical experience. Auditing management’s estimate of the ACL and related provision for credit losses was complex due to the allowance models used, high degree of subjectivity in evaluating management’s development of forecasts of future economic conditions (“economic scenarios”), probability weighting of economic scenarios, and qualitative reserves used in the general allowance.How We Addressed the Matter in Our AuditWe obtained an understanding, evaluated the design and tested the operating effectiveness of internal controls over the ACL process, including, among others, controls over the development, operation, and monitoring of economic scenarios, probability weighting of economic scenarios and qualitative reserves used in the allowance results. We involved EY specialists in testing management’s models including evaluating model methodology, model performance and testing key modeling assumptions as well as controls covering the economic scenarios used by the ACL models. Additionally, with the support of EY specialists, we assessed the economic scenarios and related probability weights by evaluating management’s methodology and agreeing a sample of key economic variables used to external sources. We also performed various sensitivity analyses and analytical procedures, including comparison of a sample of the key economic variables to alternative external sources and historical statistics. With respect to general ACL models, with the support of EY specialists, we evaluated model design and re-performed the calculation for a sample of models. We also tested the appropriateness of key inputs and assumptions used in these models by agreeing a sample of inputs to source documentation.We evaluated the overall ACL amount, including model estimates, qualitative reserves
