ABSTRACT This paper discusses Zillmer's reserve of last survivor endowment life insurance. Last survivor is life insurance of two person who are x years and y years old with a condition that premium is payed until the last death of insurance clients. Zillmer's reserve is modied prospective's reserve using the size of Zillmer's rate. The value of reserves is obtained by determining the sin…
ABSTRACT This final project formulates premium of contingent term life insurance based on Makeham’s law for two persons at the age x and y years old. Contingent life insurance is an insurance whose payment are based on the sequence of the deceased insured. In determining the order in which death is delayed, the compound contingent function is used. In this final project, term life annuit…
