The maximum interest rate applied during the stated period to monetary deposits made by or on behalf of policyholders for contracts that may contractually vary the amount and timing of premium payments without the approval of the insurer and in which premium payments are credited to the policyholder balance, against which amounts are assessed for contract services and to which amounts are credited as income. The policyholder balance provides a base upon which interest accrues to the policyholder and, when compared with the death benefit amount, fixes the insurer's net amount at risk. The insurer can often adjust the schedule of amounts assessed for contract services and the rate at which interest is credited to the policyholder balance.
