 economic conditions. The methodology for estimating the amount of expected credit losses has two basic components: first, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics and second an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. The Company's ACL model methodology is to build a reserve rate using historical life of loan default rates combined with assessments of current loan portfolio information and current and forecasted economic environment and business cycle 41

information. The model uses statistical analysis to determine the life of loan default rates for the quantitative component and analyzes qualitative factors (Q-Factors) that assess the current loan portfolio conditions and forecasted economic environment and collateral values. Below is the general overview our ACL model. Loans that Share Similar Risk Characteristics with Other Loans For loans that share similar risk characteristics, loans are segregated into loan pools based on similar risk characteristics, like product types or primary source of repayment to estimate the ACL. Historical Loss Rates The Company analyzed loan data from a full economic cycle, to the extent that data was available, to calculate life of loan loss rates. Based on the current economic environment and available loan level data, it was determined the Loss Horizon Period ("LHP") should begin prior to the economic recession that began in 2007. The Company monitors and reviews the LHP on an annual basis to determine appropriate time frames to be included based on economic indicators. Under current expected credit losses methodology ("CECL"), the Company groups pools of loans by similar risk characteristics. Using these pools, sub-pools are established at a more granular level incorporating delinquency status and original FICO or original LTV (for consumer loans) and risk ratings (for commercial loans). Using the pool and sub-pool structure, cohorts are established historically on a quarterly basis containing the population in these sets as of that point in time. After the establishment of these cohorts, the loans within the cohorts are then tracked from that point forward to establish long-term Probability of Default ("PD") at the sub-pool level and Loss Given Default ("LGD") for the pool level. These historical cohorts and their PD/LGD outcomes are then averaged together to establish expected PDs and LGDs for each sub-pool. Once historical cohorts are established, the loans in the cohort are tracked moving forward for default events. The Company has defined default events as the first dollar of loss. If a loan in the cohort has experienced a default event over the LHP then the balance of
