Alternative term for ‘pay as you go’, a method of calculating life insurance risk premiums on a year-byyear basis. Each premium reflects the chance that the policyholder will die in the following year plus an allowance for expenses. It is suitable where term (temporary) insurance is purchased on a year-by-year basis, e.g. as group life cover. The influx of new members helps to stabilise the overall annual cost. The level annual premium system is more appropriate for individual lives.
