Purpose • Introduce Gap and Residual Value coverages and the methods of estimating unearned premium reserve for these coverages.
Topics of Discussion • Description of Coverages • Sellers • Underwriters • UEP Reserve for Residual Value • UEP Reserve for Gap
Description of Coverages • Excess of loan balance over book value: • Purchase price above book value • Low, zero or negative down payment • Loan amortization vs. vehicle depreciation • Optimistic residual values • After-market extras • Financed insurance coverages
Description of Coverages • Covered Events • Gap - total loss of vehicle (e.g. theft or collision) • Residual Value - maturity of loan
Description of Coverages • Common Additional Benefits - Gap • auto insurance deductible • 1 or 2 delinquent payments • New car purchase bonus
Sellers • Auto dealers • Financing source • Auto insurer
Underwriters • Service Contract or Credit Insurer • Auto Insurer • Bank / Finance Company (Debt Cancellation)
UEP Reserve for Residual Value • No refund value • Timing of losses known • Probability of loss unknown at inception • Base reserve on assumed combined ratio • As business matures, adjust combined ratio assumption
UEP Reserve for Gap • Refund Value (Rule of 78, Pro-Rata) • Other tests
UEP Reserve for Gap • Estimating Exposure for each month
UEP Reserve for Gap • Estimating Exposure for each month - example
UEP Reserve for Gap • Estimating Probability of Loss (frequency) • Experience under existing book of gap contracts • Separate determination of severity (based on exposure) and frequency. • Total loss data from auto insurance statistics
Conclusion • UEP Reserve for Residual Value is a guess at inception and must be adjusted as residual values develop • UEP Reserve for Gap is generally determined by refund value • Other tests can reveal inadequate pricing or longer exposure period
