S.C. Code Ann. § 9-16-340 – Investment of retirement system assets by State Budget and Control Board; advisors; annual investment plan; required plan provisions

(A) The State Budget and Control Board, as trustee of the retirement system, shall invest and reinvest the assets of the retirement systems as provided in Section 9-1-1310. The State Treasurer shall serve as the agent of the board with respect to investments made pursuant to Article 7, Chapter 9, Title 11. Investments allowed by law in equities may be made by the board in the manner it shall determine, consistent with Section 9-16-330 and consistent with its fiduciary duties with respect to the retirement funds. The board may employ or retain administrators, agents, consultants, or other advisors it considers necessary with respect to making equity investments. The board is subject to the provisions of Chapter 23 of Title 1, the Administrative Procedures Act, in the implementation of this article.
(B) After receiving the proposed plan of the panel, the board shall adopt an annual investment plan, which must be implemented by the board. The board shall regularly review the plan implementation and make amendments as it considers appropriate.
(C) The plan adopted must provide:
1. (1) the minimum and maximum portions of system assets that may be allocated to equity investments on an ongoing basis not to exceed forty percent and the minimum and maximum portions of system assets not to exceed ten percent that may be allocated to additional equity investment during the plan fiscal year. When investments in equities attain the maximum allocation allowed by this item, up to forty percent of current member and employer contributions to the retirement system may be invested in equities. If, due to growth in value of equity investments, equity investments exceed forty percent of the total assets of the retirement system, this subsection does not require the sale of equities to reduce the percentage of equities to forty percent;
2. (2) preference to brokerage firms domiciled in this State for conducting nondiscretionary brokerage transactions if these brokerage firms are able to meet the test of equal service and best execution in the purchase and sale of authorized investments.
