S.D. Codified Laws § 58-12-30
Any carrier who is or has provided commercial property casualty coverage in this state shall provide, at the written request of the insured, annual reports of the claims experience of that insured for the immediate past policy period and for any time frames which are not in excess of three years prior to the policy period for which the request was made. A carrier is not required to provide any claim information that pertains to a prior carrier's experience with that insured. The claims report shall be in sufficient detail so as to provide the insured with data sufficient to assess the insured's future commercial property casualty insurance needs. The director may promulgate rules pursuant to chapter 1-26 regarding the content and time frames for the annual reports.
