S.D. Codified Laws § 58-5-149
Insurers shall report acquisitions and dispositions on a nonconsolidated basis unless the insurer is part of a consolidated group of insurers which utilizes an intercompany pooling agreement or arrangement or a one hundred percent reinsurance agreement whereunder the ceding company has ceded substantially one hundred percent of its direct and assumed business to a pool. An insurer is deemed to have ceded "substantially one hundred percent" of its direct and assumed business to a pool if the insurer has less than one million dollars of total direct plus assumed written premiums during a calendar year that are not subject to the pooling agreement or arrangement and the net income of the business not subject to the pooling agreement or arrangement represents less than five percent of the insurer's capital and surplus. If a group of insurers reports on a consolidated basis, the report shall identify the individual insurers that are members of the group.
