S.D. Codified Laws § 58-26-82
If for any life insurance policy issued on or after January 1, 1986, for which the gross premium in the first policy year exceeds that of the second year and for which no comparable additional benefit is provided in the first year for the excess and which provides an endowment benefit or a cash surrender value or a combination thereof in an amount greater than the excess premium, the foregoing provisions of § 58-26-81 and this section shall be applied as if the method actually used in calculating the reserve for the policy were the method described in § 58-26-75, ignoring the second paragraph of § 58-26-75. The minimum reserve at each policy anniversary of a policy shall be the greater of the minimum reserve calculated in accordance with § 58-26-75, including the second paragraph of that section, and the minimum reserve calculated in accordance with § 58-26-81 and this section.
