S.C. Code § 59-133-270
In order to avail themselves of the authorizations set forth in this article, the trustees shall from time to time adopt resolutions providing for the issuance of bonds of Francis Marion, within the limitations herein mentioned, which resolutions shall prescribe the tenor, terms, and conditions of such bonds. Such bonds must be issued as serial or term bonds, maturing in equal or unequal amounts, at such times and on such occasions as the trustees determine. The last maturing bonds of any issue must be expressed to mature not later than thirty years from their date, and the first maturing bonds of any issue, issued pursuant to this article, shall fall due within three years from their date. The bonds shall bear such rates of interest, payable on such occasion, as the trustees shall prescribe, and the bonds must be in such denominations, must be payable in such medium of payment, and at such place as such resolutions prescribe. All bonds may be issued with a provision permitting their redemption on any interest payment date prior to their respective maturities. Bonds made subject to redemption prior to their stated maturities may contain a provision requiring the payment of a premium for the privilege of exercising the right of redemption, in such amount or amounts as the trustees shall prescribe in the resolutions authorizing their issuance. All bonds that are subject to redemption shall contain a statement to that effect on the face of each bond. The resolutions authorizing their issuance shall contain provisions specifying the manner of call for redemption and the notice of such call that must be given.
