(A) However, with respect to rate years beginning January 1, 1972, and thereafter, an employer who has been subject to three (3) or more years of benefit risk may voluntarily elect to be rated each year on the basis of total taxable wages paid during the preceding calendar year instead of the average of the annual payrolls for the last three (3) or last five (5) preceding calendar years, whichever is the lesser.

(b) The director shall for each rate year:

(1) (A) (i) Periodically notify each employer of the regular benefits paid that are chargeable to the employer's account.

(ii) The notification shall become conclusive and binding upon the employer unless within thirty (30) days after mailing of the notice the employer files an application for review and redetermination as provided in subdivision (c)(1) of this section.

(B)

(i) With the exception of charges that might be changed under § 11-10-703(a)(2)(A)(ii), an application for review and redetermination shall be made the first time that charges appear on the employer's account as reflected on the quarterly statement of paid benefits.

(ii) The director may, if he or she finds the reasons set forth by the employer insufficient to change the benefit charges to the employer's account or the rate of contributions, deny the application; otherwise, it shall be granted and the charges adjusted and the rate redetermined.

(C) The employer shall be promptly notified by mailing to the employer's last known address the denial of the employer's application or of the redetermination, both of which shall become final and conclusive at the date of mailing of notification thereof.
