 allowance for credit losses of $2.2 billion reflects management's expected credit losses in the loan and lease portfolio of $135.6 billion as of December 31, 2024. For purposes of determining the level of the allowance for credit losses, management evaluates the Company’s loan and lease portfolio by type. Management utilizes statistically developed models to project principal balances over the remaining contractual lives of the loan portfolios and to determine estimated credit losses through a reasonable and supportable forecast period. Model forecasts may be adjusted for inherent limitations or biases that have been identified through independent validation and back-testing of model performance to actual realized results. Management may adjust forecasted loss estimates for inherent limitations or biases in the models as well as for other factors that may not be adequately considered in its quantitative methodologies including the impact of portfolio concentrations, imprecision in its economic forecasts, geopolitical conditions and other risk factors that might influence its loss estimation process. 

The principal considerations for our determination that performing procedures relating to the allowance for credit losses, specifically certain adjustments to model forecasts, is a critical audit matter are (i) the significant judgment by management in determining the adjustments to model forecasts, (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and in evaluating audit evidence related to management’s determination of these adjustments to

model forecasts, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the Company’s allowance for credit losses estimation process, including controls relating to the allowance for credit losses estimation process for certain adjustments to model forecasts. These procedures also included, among others, testing management’s process for determining the allowance for credit losses and these adjustments to model forecasts, including evaluating the appropriateness of management’s methodology, testing the data utilized by management and evaluating the reasonableness of significant assumptions relating to these adjustments to model forecasts. Evaluating significant assumptions relating to these adjustments to model forecasts involved evaluating portfolio composition and concentration, as well as relevant market data. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of management’s methodology and the reasonableness of significant assumptions relating to these adjustments to model forecasts.
