Finance Charges Sources of Revenue. Finance charges is comprised of: (1) interest income earned on Loans; (2) administrative fees earned from ancillary products; (3) program fees charged to Dealers under the Portfolio Program; (4) Consumer Loan assignment fees charged to Dealers; and (5) direct origination costs incurred on Dealer Loans. We provide Dealers the ability to offer vehicle service contracts to consumers through our relationships with Third Party Providers (TPPs). A vehicle service contract provides the consumer protection by paying for the repair or replacement of certain components of the vehicle in the event of a mechanical failure. The retail price of the vehicle service contract is included in the principal balance of the Consumer Loan. The wholesale cost of the vehicle service contract is paid to the TPP, net of an administrative fee retained by us. The difference between the wholesale cost and the retail price to the consumer is paid to the Dealer as a commission. Under the Portfolio Program, the wholesale cost of the vehicle service contract and the commission paid to the Dealer are charged to the Dealers advance balance. TPPs process claims on vehicle service contracts that are underwritten by third party insurers. We bear the risk of loss for claims on certain vehicle service contracts that are reinsured by us. We market the vehicle service contracts directly to our Dealers. We provide Dealers the ability to offer Guaranteed Asset Protection (GAP) to consumers through our relationships with TPPs. GAP provides the consumer protection by paying the difference between the loan balance and the amount covered by the consumers insurance policy in the event of a total loss of the vehicle due to severe damage or theft. The retail price of GAP is included in the principal balance of the Consumer Loan. The wholesale cost of GAP is paid to the TPP, net of an administrative fee retained by us. The difference between the wholesale cost and the retail price to the consumer is paid to the Dealer as a commission. Under the Portfolio Program, the wholesale cost of GAP and the commission paid to the Dealer are charged to the Dealers advance balance. TPPs process claims on GAP contracts that are underwritten by third party insurers. Program fees represent monthly fees charged to Dealers for access to our Credit Approval Processing System (CAPS); administration, servicing and collection services offered by us; documentation related to or affecting our program; and all tangible and intangible property owned by Credit Acceptance. We charge a monthly fee of $599 to Dealers participating in our Portfolio Program and we collect it from future Dealer Holdback payments. Recognition Policy. We recognize finance charges under the interest method such that revenue is recognized on a level-yield basis over the life of the Loan. We calculate finance charges on a monthly basis by applying the effective interest rate of the Loan to the net carrying amount of the Loan (Loan receivable less the related allowance for credit losses). For Consumer Loans assigned subsequent to December 31, 2019, the effective interest rate is based on contractual future net cash flows. For Consumer Loan assigned prior to January 1, 2020, the effective interest rate was based on expected future net cash flows. In connection with our adoption of CECL on January 1, 2020, we have elected to report the change in the present value of credit losses attributable to the passage of time as a reduction to finance charges. As a result, for financial statement periods beginning after December 31, 2019, we allocate finance charges recognized on each Loan between the Loan receivable and the related allowance for credit losses. The amount of finance charges allocated to the Loan receivable is equal to the effective interest rate applied to the Loans receivable balance. The reduction of finance charges allocated to the allowance for credit losses is equal to the effective interest rate applied to the allowance for credit losses balance. For financial statement periods beginning prior to January 1, 2020, the entire amount of finance charges recognized on each Loan was allocated to the Loan receivable.
