= 2. Consider a ground-up model of individual losses. The number of losses, NI, has probability generating function Pn1(2) = Ba(2 1), where a is a parameter and B is functionally independent of a. Individual losses follow an exponential distribution with mean 0. The number of losses and individual loss amounts are mutually independent. An insurer would like to model the impact of imposing an ordinary de- ductible of d on each loss and reimbursing only 100c%, 0
