(a) If the commission does not compute a surplus credit under Section 204.0651, the commission may use any portion of the surplus under Section 204.065 that is not used to pay bond obligations to compute an annual surplus credit rate for an employer entitled to an experience rate on the computation date.
(b) The surplus credit rate is computed by multiplying the surplus ratio computed under Section 204.066 by the employer's general and replenishment tax rates for the preceding year.
(c) The surplus credit rate shall be subtracted from the sum of the general and replenishment tax rates. The remainder may not be less than zero. The results shall be rounded to the nearest hundredth.
(d) An employer may not receive a surplus credit rate if any delinquent contributions are due on the computation date, but is eligible for a surplus credit rate beginning on the calendar quarter following the quarter in which the delinquent contributions are paid.
