(A) In addition to other types of retirement provided by this chapter, a member who has attained the age of fifty-five years and who has at least twenty-five years of creditable service may elect early retirement. A member electing early retirement shall apply in the manner provided in Section 9-1-1510.
(B) The benefits for a member electing early retirement under this section must be calculated in the manner provided in Section 9-1-1550, except that in lieu of any other reduction factor, the member's early retirement allowance is reduced by four percent a year, prorated for periods less than one year, for each year of creditable service less than thirty. However, a member's early retirement allowance is not reduced if the member pays into the system, in a lump sum payment before the member's retirement, an amount equal to twenty percent of the member's earnable compensation or the average of the member's twelve highest consecutive fiscal quarters of compensation at the time of payment, whichever is greater, prorated for periods less than one year for each year of creditable service less than thirty. The member's retirement must occur not more than ninety days after the date of the payment.
(C) A member who elects early retirement under this section is ineligible to receive any cost-of-living increase provided by law to retirees until the second July first after the date the member attains age sixty; or the second July first after the date the member would have thirty years' creditable service had he not retired, whichever is earlier.

(a) the date the member attains age sixty, or
(b) the date the member would have thirty years' creditable service had he not retired.
(2) A member taking early retirement may maintain coverage under the State Insurance Benefits Plan until the date his coverage is reinstated pursuant to item (1) of this subsection by paying the total premium cost, including the employer's contribution, in the manner provided by the Division of Insurance Services of the State Budget and Control Board.
