S.D. Codified Laws § 58-14-16.30
If the director determines that an assuming insurer no longer meets a requirement under §§ 58-14-16.23 to 58-14-16.34, inclusive, the director may revoke or suspend the eligibility of the assuming insurer.
While an assuming insurer's eligibility is suspended, no reinsurance agreement issued, amended, or renewed after the effective date of the suspension qualifies for credit except to the extent that the assuming insurer's obligations under the contract are secured in accordance with § 58-14-16.
If an assuming insurer's eligibility is revoked, no credit for reinsurance may be granted after the effective date of the revocation with respect to any reinsurance agreements entered into by the assuming insurer, including reinsurance agreements entered into prior to the date of revocation, except to the extent that the assuming insurer's obligations under the contract are secured in a form acceptable to the director and consistent with the provisions of § 58-14-16.
