A type of nonparticipating whole life policy that specifies two premium rates—both a maximum guaranteed rate and a lower rate. The insurer charges the lower premium rate when the policy is purchased and guarantees that rate for at least a stated period of time, after which the insurer uses its actual mortality, interest, and expense experience to establish a new premium rate that may be higher or lower than the previous premium rate. Also known as nonguaranteed premium life insurance policy and a variable premium life insurance policy.
