S.C. Code Regs. § § 69-4
Each and every domestic insurance company having life and/or accident and health insurance in force shall submit, with the annual statement required by this Department, a copy of the valuation tabulation used in the determination of its reported life and accident and health reserve. If the tabulation is a summarization, each company shall be prepared to support each and every phase of the summary by detailed cards, listings, or some form of acceptable running inventory. This detailed information shall be maintained until verification of the valuation has been made by a representative or representatives of this Department.
Each company shall take the necessary steps to acquire and maintain, in its home office, the necessary reserve tables for proper calculation of reserves on all contracts in force as of the applicable valuation date. If the insurance is of such a nature that no appropriate mortality or morbidity tables have been published, the company may use methods and approximations warranted by company experience and approved by the Chief Insurance Commissioner.
