The date of issue of a policy for the purpose of this section shall be the date as of which the rated age of the insured is determined.
The basic cash value shall be equal to the present value, on such anniversary, of the future guaranteed benefits which would have been provided for by the policy, excluding any existing paid-up additions and before deduction of any indebtedness to the insurer, if there had been no default, less the then present value of the nonforfeiture factors, as hereinafter defined, corresponding to premiums which would have fallen due on and after such anniversary. Provided, however, that the effects on the basic cash value of supplemental life insurance or annuity benefits or of family coverage, as described in subsection D or H of this section, whichever is applicable, shall be the same as are the effects specified in subsection D or H of this section, whichever is applicable on the cash surrender values defined in that subsection.
The nonforfeiture factor for each policy year shall be an amount equal to a percentage of the adjusted premium for the policy year, as defined in subsection G or I of this section, whichever is applicable. Except as is required by the next succeeding sentence of this paragraph, such percentage:
Provided, that no basic cash value may be less than the value which would be obtained if the adjusted premiums for the policy, as defined in subsection G or I of this section, whichever is applicable, were substituted for the nonforfeiture factors in the calculation of the basic cash value.
All adjusted premiums and present values referred to in this section shall for a particular policy be calculated on the same mortality and interest bases as are used in demonstrating the policy's compliance with the other subsections of this section. The cash surrender values referred to in this subsection shall include any endowment benefits provided for by the policy.
Any cash surrender value available other than in the event of default in a premium payment due on a policy anniversary, and the amount of any paid-up nonforfeiture benefit available under the policy in the event of default in a premium payment shall be determined in manners consistent with the manners specified for determining the analogous minimum amounts in subsections B, C, D and K and paragraph 4 of subsection I of this section. The amounts of any cash surrender values and of any paid-up nonforfeiture benefits granted in connection with additional benefits such as those listed as items (1) through (6) in subsection K of this section shall conform with the principles of this subsection.
