California Code, Insurance Code - INS § 10507.3

(1) The reserves for all investment return assurance policies shall be computed and maintained on a basis which shall place an actuarially sound value on the liabilities under such policies. To provide a basis for the determination of such actuarially sound values, the commissioner, from time to time, shall adopt rules requiring the use of appropriate tables of morbidity, mortality, interest rates, and valuation methods for such reserves.

(2) Any paid-up nonforfeiture benefit available under the policy in the event of default in a premium payment due on any policy anniversary shall be such that its present value as of such anniversary shall be at least equal to the ratio of the number of years the policy has been in force to the total premium-paying period times the present value of benefits payable had the policy been kept in full force and effect for the total premium-paying period.
