(A) A fee agreement must contain the requirement that a fee in lieu of property tax be paid as follows:

1. (1) During the exemption period, the sponsor shall pay, or be responsible for payment, to the county the annual fee payment in connection with the economic development property which has been placed in service, in an amount not less than the property taxes that would be due on the economic development property if it were taxable but using:

   1. (a) an assessment ratio of not less than six percent, or four percent for those projects qualifying under the enhanced investment definition;

   2. (b) a millage rate that is, either:

      1. (i) fixed for the life of the fee; or
      2. (ii) is allowed to increase or decrease every fifth year in step with the average cumulative actual millage rate applicable to the project based upon the preceding five-year period; and

   3. (c) a fair market value for the economic development property:

      1. (i) if real property is constructed for the fee or is purchased in an arm's length transaction, the fair market value of real property is determined by using the original income tax basis for South Carolina income tax purposes without regard to depreciation, otherwise the property must be reported at its fair market value for ad valorem property taxes as determined by appraisal. The fair market value estimate established for the first year of the fee remains the fair market value of the real property for the life of the fee;
      2. (ii) fair market value for personal property is determined by using the original tax basis for South Carolina income tax purposes less depreciation allowable for property tax purposes, except that the sponsor is not entitled to extraordinary obsolescence; and

   4. (d) to establish the millage rate for purposes of subsection (A)(1)(b)(i) or the first five years millage under (A)(1)(b)(ii), the millage rate must be no lower than the cumulative property tax millage rate levied by, or on behalf of, all taxing entities within which the project is located on either:

      1. (i) June thirtieth of the year preceding the calendar year in which the fee agreement is executed; or
      2. (ii) the millage rate in effect on June thirtieth of the calendar year in which the fee agreement is executed.
2. (2) The fee calculation must be made so that the property, if taxable, is allowed all applicable property tax exemptions except the exemption allowed under Section 3(g) of Article X of the Constitution of this State and the exemption allowed pursuant to Section 12-37-220(B)(32) and (34).
3. (3) If the project subject to the fee agreement involves an investment of at least forty-five million dollars, the county and the sponsor may agree to pay the fees established in subsection (A)(1) based on an alternative payment method yielding a net present value of the fee schedule as calculated in subsection (A)(1) provided the sponsor agrees to a millage rate as established in subsection (A)(1)(b)(i). Net present value calculations must use a discount rate equivalent to the yield in effect for new or existing United States Treasury bonds of similar maturity as published during the month in which the fee agreement is executed. If no yield is available for the month in which the fee agreement is executed, the last published yield for the appropriate maturity available must be used. If there are no bonds of appropriate maturity available, bonds of different maturities may be averaged to obtain the appropriate maturity.

(B)

1. (1) If a sponsor disposes of an item of economic development property, the fee must be reduced by the amount of the fee applicable to that item of economic development property. Economic development property is disposed of only when it is scrapped or sold or it is removed from the project. If it is removed from the project, it is subject to ad valorem property taxes to the extent the property remains in the State.
2. (2) If the sponsor used an alternative payment method as provided in subsection (A)(3), the fee applicable to the item of property which was disposed of must be recomputed in accordance with subsection (A)(1) and, to the extent that the amount which would have been paid with respect to this item under subsection (A)(1) exceeds the fee actually paid by the sponsor, the sponsor shall pay the difference with the next annual fee payment due after the item of property is disposed of. This amount is subject to interest as provided in Section 12-54-25.
