 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 the loan at the time of cohort establishment becomes part of the numerator of the PD calculation. The Loss Given Probability of Default ("LGPD") or Expected Loss ("EL") is the weighted average PD for each sub-pool cohort times the average LGD for each pool. The output from the model then is a series of EL rates for each loan sub-pool, which are applied to the related outstanding balances for each loan sub-pool to determine the ACL reserve based on historical loss rates.Q-FactorsThe Q-Factors adjust the expected historic loss rates for current and forecasted conditions that are not provided for in the historical loss information. The Company has established a methodology for adjusting historical expected loss rates based on these more recent or forecasted changes. The Q-Factor methodology is based on a blend of quantitative analysis and management judgment and reviewed on a quarterly basis.
