 occur over the life of the asset. Executive management reviews and advises on the adequacy of the allowance on a quarterly basis, which is maintained at a level that management deems to be sufficient to cover expected credit losses within the loan and lease portfolios. An ACL on accrued interest for a loan is not measured since accrued interest income is reversed against interest income for non-accrual loans immediately after their non-accrual classification.The ACL on loans and leases is determined using the CECL model, whereby an expected lifetime credit loss is recognized at the origination or purchase of an asset, including those acquired through a business combination, which is then reassessed at each reporting date over the contractual life of the asset. The calculation of expected credit losses includes consideration of past events, current conditions, and reasonable and supportable economic forecasts that affect the collectability of the reported amounts. Generally, expected credit losses are determined through a pooled, collective assessment of loans and leases with similar risk characteristics. However, if the risk characteristics of a loan or lease change such that it no longer aligns to that of the collectively assessed pool, it is removed from the population and individually assessed for credit losses. The total ACL on loans and leases recorded by management represents the aggregated estimated credit loss determined through both the collective and individual assessments.

Collectively Assessed Loans and Leases. Collectively assessed loans and leases are segmented based on product type and credit quality, and expected losses are determined using models that follow a PD, LGD, or EAD framework. Under these frameworks, expected credit losses are calculated as the product of the probability of a loan defaulting, expected loss given the occurrence of a default, and the expected exposure of a loan at default. Summing the product across loans over their lives yields the lifetime expected credit losses for a given portfolio. The Company’s PD and LGD calculations are predictive models that measure the current risk profile of the loan pools using forecasts of future macroeconomic conditions, historical loss information, loan-level risk attributes, and credit quality indicators. The calculation of EAD follows an iterative process to determine the expected remaining principal balance of a loan based on historical paydown rates for loans of a similar segment within the same portfolio. The calculation of portfolio exposure in future quarters incorporates expected losses, the loan’s amortization schedule, and prepayment rates.The Company’s models incorporate a single economic forecast scenario and macroeconomic assumptions over a reasonable and supportable forecast period. The development of the reasonable and supportable forecast assumes that each portfolio will revert to its long
