(1) The minimum cash surrender values shall be determined separately for the basic policy and any benefits and riders for which premiums are paid separately. The following requirements pertain to a basic policy and any benefits and riders for which premiums are not paid separately.

(a) The minimum cash surrender value (before adjustment for indebtedness and dividend credits) available on a date as of which interest is credited to the policy shall be equal to ((A)-(B)-(C)-(D)), where:

(i) (A) is the present value of all future guaranteed benefits.

(ii) (B) is the present value of future adjusted premiums. The adjusted premiums are calculated as described in RCW 48.76.050 (1) and (2), or in (4)(a), as applicable. If RCW 48.76.050 (4)(a) is applicable, the nonforfeiture net level premium is equal to the quantity PVFB/äx where PVFB is the present value of all benefits guaranteed at issue assuming future premiums are paid by the policyowner and all guarantees contained in the policy or declared by the insurer, and where äx is the present value of an annuity of one per year payable on policy anniversaries beginning at age x and continuing until the highest attained age at which a premium may be paid under the policy.

(iii) (C) is the present value of any quantities analogous to the nonforfeiture net level premium which arise because of guarantees declared by the insurer after the issue date of the policy. äx shall be replaced by an annuity beginning on the date as of which the declaration became effective and payable until the end of the period covered by the declaration.

(iv) (D) is the sum of any quantities analogous to (B) which arise because of structural changes in the policy.

(v) Structural changes are those changes which are separate from the automatic workings of the policy. Such changes usually would be initiated by the policyowner and include changes in the guaranteed benefits, changes in latest maturity date, or changes in allowable premium payment period.

(vi) In effecting structural changes, consistent methods are prescribed when calculating nonforfeiture values. Several such methods are possible, but perhaps the simplest such method would be that of maintaining proportionality between the guaranteed maturity fund and guaranteed maturity premium values and the current face amount. In applying this method, guaranteed maturity fund and guaranteed maturity premium values could be calculated per dollar of face amount and simply multiplied by the new face amount. This would eliminate much of the complexity involved in other methods.

(b) Future guaranteed benefits are determined by (i) projecting the policy value, taking into account future premiums, if any, and using all guarantees of interest, mortality, expense deduction, etc., contained in the policy or declared by the insurer; and (ii) taking into account any benefits guaranteed in the policy or by declaration which do not depend on the policy value.

(c) All present values shall be determined using (i) an interest rate (or rates) specified in chapter 48.76 RCW for policies issued in the same year and (ii) the mortality rates specified for policies issued in the same year or contained in such other table as may be approved by the commissioner for this purpose.

(2) Minimum paid-up nonforfeiture benefits. If a universal life insurance policy provides for the optional election of a paid-up nonforfeiture benefit, it shall be such that its present value shall be at least equal to the cash surrender value provided for by the policy on the effective date of the election. The present value shall be based on mortality and interest standards at least as favorable to the policyowner as the mortality and interest standards permitted for paid-up nonforfeiture benefits by chapter 48.76 RCW. In lieu of the paid-up nonforfeiture benefit, the insurer may provide actuarially equivalent alternatives, calculated on a guaranteed or more favorable basis defined in the policy, which provide a greater amount or longer period of death benefits, or, if applicable, a greater amount of earlier payment of endowment benefits. Such alternative paid-up nonforfeiture benefits must be available for election by the policyowner for at least sixty days after the due date of the premium in default.

(3) Nonforfeiture benefits for substandard issues. The cash and nonforfeiture values of a substandard issue shall be calculated according to the same principles and formulas as the standard issues affording equitable treatment of the several classes of insureds.
