Step-by-step explanation:
The three primary elements in life insurance ratemaking are: mortality, expenses, and interest or loading. Mortality rates are the estimates of the number of individuals that will die within a given period. Expenses refer to the costs of running the insurance company, including administrative costs and processing insurance claims.
Loading, which is also known as the safety margin, represents the insurance company's profit goal plus a protective margin for unforeseen contingencies. Moreover, loading can also be considered as incorporating the insurance company's cost of capital.
