 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 reasonableand supportable forecast period. The development of the reasonable and supportable forecast assumes that each portfolio will revert to its long-term loss rate expectation. The reasonable and supportable forecast period is two years, after which the reversion period is one year. Models use output reversion and revert to mean historical portfolio loss rates on a straight-line basis in the third year of the forecast.

The Company incorporates forecasts of macroeconomic variables in the determination of expected credit losses. Macroeconomic variables are selected for each class of financing receivable based on relevant factors, such as asset type and the correlation of the variables to credit losses, among others. Data from the forecast scenario of these macroeconomic variables are used as inputs to the modeled loss calculation.

A portion of the collective ACL is comprised of qualitative adjustments for
