The minimum values as specified in §§ 58-15-86 to 58-15-89, inclusive, and 58-15-91 of any paid-up annuity, cash surrender, or death benefits available under an annuity contract shall be based upon minimum nonforfeiture amounts as defined in this section:
The interest rate used in determining minimum nonforfeiture amounts shall be an annual rate of interest determined as the lesser of three percent per annum and the following, which shall be specified in the contract if the interest rate will be reset:
The redetermination date, basis, and period, if any, shall be stated in the contract. The basis is the date or average over a specified period that produces the value of the five-year constant maturity treasury rate to be used at each redetermination date.
During the period or term that a contract provides substantive participation in an equity indexed benefit, it may increase the reduction described above by up to an additional one hundred basis points to reflect the value of the equity index benefit. The present value at the contract issue date, and at each redetermination date thereafter, of the additional reduction may not exceed the market value of the benefit. The director may require a demonstration that the present value of the additional reduction does not exceed the market value of the benefit. Lacking such a demonstration that is acceptable to the director, the director may disallow or limit the additional reduction.
The director may promulgate rules pursuant to chapter 1-26 to implement the provisions of this section and to provide for further adjustments to the calculation of minimum nonforfeiture amounts for contracts that provide substantive participation in an equity index benefit and for other contracts that the director determines adjustments are justified.
