multiplied by(2) the ratio that the number of the member's years of creditable service at early retirement bear to the number of years of such service the member would have completed had the member remained in service to the member's normal retirement date.(f) Upon written application to the Board:(1) any Group C member who has attained the age of 57 or completed at least 25 years of creditable service as of June 30, 2010, has not attained the age of 62 but has attained the age of 55 and completed between five and 30 years of creditable service may retire on an early retirement allowance on the first day of the calendar month next following the filing of the application or the member's separation from service, whichever date is later;(2) any Group C member who has not attained the age of 57 or completed at least 25 years of creditable service as of June 30, 2010, and neither has attained the age of 65 nor has at least 90 years of combined age and years of creditable service, but who has attained age 55 and completed five years of creditable service, may retire on an early retirement allowance on the first day of the calendar month next following the filing of the application or the member's separation from service, whichever date is later.(g) Upon early retirement, a Group C member:(1) who has attained the age of 57 or completed at least 25 years of creditable service as of June 30, 2010 shall receive an early retirement allowance equal to the service retirement allowance reduced by one-half of one percent for each month the member is under age 62 at the time of early retirement;(2) who has not attained the age of 57 or completed at least 25 years of creditable service as of June 30, 2010, and neither has attained the age of 65 nor has at least 90 years of combined age and years of creditable service, shall receive an early retirement allowance, which shall be the actuarial equivalent of the normal retirement allowance computed under subsection (c) of this section, based on the average final compensation and years of creditable service at the date of early retirement.(h) Any member who retires prior to age 62 may, at any time prior to the date the first payment on account of the member's retirement allowance normally becomes due, elect to convert the retirement allowance otherwise payable to the member after retirement into a reduced retirement allowance that is its actuarial equivalent and is of such amount that, with the member's primary insurance amount under Title II of the Social Security Act, the member will receive, so far as possible, the same amount each year before and after such primary insurance amount commences.(i) When a member has a minimum of 25 years of creditable service, he or she may elect to purchase up to five years of additional service credit. A member who has attained the age of 57 and completed at least 25 years of creditable service as of June 30, 2010 and makes an election under this subsection shall deposit in the Pension Fund by a single contribution an amount computed at regular interest to be sufficient to provide at normal retirement an annuity equal to one and two-thirds percent of the member's average final compensation multiplied by the number of years purchased. A member who has not attained the age of 57 or completed at least 25 years of creditable service as of June 30, 2010 and makes an election under this subsection shall deposit in the Pension Fund by a single contribution an amount computed at regular interest to be sufficient to provide at normal retirement an annuity equal to one and two-thirds percent of the member's average final compensation for each year up to 20 years of service and two percent of the member's average final compensation for each year thereafter. If through a negotiated agreement or binding contract, a school district or supervisory union is required to purchase the whole or part of the additional years of service credit necessary to enable the member to take normal retirement, the school district or supervisory union may deposit a single contribution into the Pension Fund or make the contribution in four equal annual payments on dates established by the State Treasurer. If a school district or supervisory union elects to make the contribution in four equal annual payments, it shall, in addition, pay interest at the actuarially assumed interest rate at the time of each annual payment. Any payment not received within 30 days after the date it is due shall be considered delinquent and the delinquent payment and interest may be recovered by action in a court of competent jurisdiction against the school district or supervisory union liable therefor or may be deducted by the State Treasurer from any other monies payable to such school district or supervisory union by the State or any department or agency thereof.Amended 1959, No. 72, §§ 1, 2, eff. 4/1/1959; 1961, No. 85, § 1; 1963, No. 182, § 1; 1967, No. 172, § 1; 1969, No. 72; 1971, No. 201 (Adj.
