S.C. Code Ann. § 34-28-520: Investments in service corporations.

(1) Every association shall have the power to invest in the capital stock, obligations or other securities of one or more service corporations, provided that at the time of any investment the aggregate amount paid for all the stock, obligations or other securities in service corporations by the association including the proposed investment shall not exceed ten percent of the assets of the association.

(2) A service corporation of an association may engage in third party real estate brokerage operations and in any business activity authorized for a service corporation of a federally chartered association by the Federal Home Loan Bank Board from time to time. If the Federal Home Loan Bank Board no longer authorizes a service corporation of a federally chartered association to engage in an activity which it had previously approved, an association may continue to engage in the activity if it receives Board approval to do so.
