computation Sec. 4. (a) A participant who is at least fifty-five (55) years of age is entitled, for the remainder of the participant's life, to a reduced monthly retirement benefit computed under subsection (b), beginning on the date specified by the participant in a written application, if
all of the following conditions are met on the date on which the benefit begins: (1) The participant's service as a member of the general assembly is terminated. (2) The participant has at least ten (10) years of service as a member of the general assembly. (3) The participant is not receiving and is not entitled to receive a salary from the state. (b) The reduced monthly benefit payable for life to a participant eligible under this section is the benefit calculated under section 3 of this chapter, multiplied by a percentage determined as follows: STEP ONE: From seven hundred eighty (780) months, which equals sixty-five (65) years, subtract the age of the participant at the participant's retirement date expressed in whole months (retirement age in months) and obtain a remainder (X). STEP TWO: (A) If the remainder (X) is less than or equal to sixty (60), multiply the remainder (X) times one-tenth percent (0.1%) and obtain a product (Y). (B) If the remainder (X) is greater than sixty (60), multiply five-twelfths percent (5/12%) times the difference obtained by subtracting sixty (60) from the remainder (X) and obtain a product. Add to this six percent (6%) and obtain a sum (Y). STEP THREE: From one hundred percent (100%) subtract the appropriate (Y). This equals the percentage used to determine the reduced monthly benefit.
