(i) For a member who is retired or who is in the Teacher Deferred Retirement Option Plan as of June 30, 2013, the multipliers used at the time of retirement or entry into the Teacher Deferred Retirement Option Plan shall remain the multipliers used to calculate the member's retirement benefits for retirement or the Teacher Deferred Retirement Option Plan.

(ii) The multiplier rate for contributory service used for the first ten (10) years of service shall not be higher than the multiplier rate for subsequent years of service; and
(iii) After a member earns ten (10) years of credited service, the board may increase the multiplier rate earned in the first ten (10) years to the standard multiplier rate for contributory service for all or part of the first ten (10) years of service.
(3) The board may adjust the multiplier rate for noncontributory service for all service rendered after June 30, 2013, as follows:
(A) The multiplier rate for noncontributory service set by the board shall remain in effect unless adjusted by the board;

(G) The board may set a special noncontributory multiplier rate for the first ten (10) years of service credit as follows:
(i) The multiplier rate for noncontributory service used for the first ten (10) years of service shall not be higher than the multiplier rate for subsequent years of service; and
(ii) After a member earns ten (10) years of credited service, the board may increase the multiplier rate earned in the first ten (10) years to the standard multiplier rate for noncontributory service for all or part of the first ten (10) years of service.
(4) A lower multiplier rate set by the board for contributory service and noncontributory service earned in the first ten (10) years of service shall not be retroactively applied.
(5) The board shall not reduce the multiplier rate for contributory service earned after the first ten (10) years of service unless the:
(A) System's actuary certifies to the board that the amortization period to pay the unfunded liabilities of the system exceeds eighteen (18) years; and
(B) Board determines that a reduction in the multiplier rate for contributory service is prudent to maintain actuarial soundness.
(c) For all service credit earned by a member after June 30, 2013, he or she shall receive a straight life annuity equal to his or her number of years of credited service multiplied by his or her final average salary as follows:
