, prepayment rates, and severity rates. The models accept as inputs key risk drivers such as: current balance, original credit bureau score, original loan-to-value ratio, type of collateral, location of collateral, delinquency status, loan age, among other characteristics. They also utilize macroeconomic forecasts of home price indices, unemployment rates, gross domestic product, and others.Vehicle Loans    The allowance for credit losses within the vehicle loan pool is calculated using a non-discounted cash flow model through a PD, LGD, and prepayment model developed by an external third-party and adjusted for asset specific risk characteristics. These classes are further divided into smaller pools of loans with similar risk characteristics such as: cars, trucks and powersport vehicles and recreational vehicles. Monthly probabilities of default and prepayments are estimated for each loan, along with estimates of exposure at default and loss given default. The model accepts as inputs key risk drivers such as loan, borrower, and collateral characteristics. It also uses macroeconomic forecasts of used car price indices, gross domestic product, unemployment rates and others.Consumer LoansThe allowance for credit losses within the consumer loan portfolio is calculated at the portfolio-level using a non-discounted cash flow method through a suite of loss rate models developed internally with the assistance of an external third-party. This class of financing receivables is further divided into credit cards, unsecured lines of credit and other consumer loans.The allowance for credit losses for credit cards and unsecured lines of credit is calculated using two transition matrix models to project portfolio-level net charge-off rates. Both models use current balance and delinquency status as key risk drivers. These models are not natively sensitive to macroeconomic forecasts. The necessary adjustments to account for current and expected macroeconomic conditions is captured via our qualitative adjustment framework.For other consumer loans, a regression model is used to project portfolio-level net charge-off rates. This model uses borrower information and macroeconomic forecasts as key inputs.Commercial Real Estate LoansThe commercial real estate loan class is further segmented into smaller pools of loans with similar risk characteristics, commercial real estate loans and small business commercial real estate loans.  The allowance for credit losses for the commercial real estate loan portfolio is calculated at the pool level using a non-discounted cash flow method through a PD/LGD model developed by an external third-party. This model projects default and severity rates. The model accepts as inputs key risk drivers such as: current balance, original loan-to-value-ratio, type of collateral, location of collateral, delinquency status, loan age
