(3) Interest, determined as provided in division (F) of this section, on the amounts specified in divisions (B)(1) and (2) of this section from the last day of the year for which the service credit in the uniform system was earned or in which payment was made to purchase or obtain military service credit to the date the transfer is made.

(C) A member participating in the STRS defined benefit plan who has at least one and one-half years of contributing service with the state teachers retirement system, is a former member of a uniform retirement system, and has received a refund of contributions to that uniform system shall, in computing years of total service, be given full credit for service credit earned under Chapter 742. or 5505. of the Revised Code or for military service credit if, for each year of service, the state teachers retirement system receives the sum of the following:

1. (1) An amount, which shall be paid by the member, equal to the amount refunded by the uniform system to the member for that year for accumulated contributions and payments for military service credit, with interest at a rate established by the state teachers retirement board on that amount from the date of the refund to the date of the payment;
2. (2) Interest, which shall be transferred by the uniform system, on the amount refunded to the member that is attributable to the year of service from the last day of the year for which the service credit was earned or in which payment was made for military service credit to the date the refund was made;

(3) An amount, which shall be transferred by the uniform system, equal to the lesser of the employer's contributions to the uniform system or the amount that would have been contributed by the employer for the service had the member been a member of the state teachers retirement system at the time the credit was earned, with interest on that amount from the last day of the year for which the service credit was earned or in which payment was made for military service to the date of the transfer. On receipt of payment from the member, the state teachers retirement system shall notify the uniform system, which, on receipt of the notice, shall make the transfer required by this division. Interest shall be determined as provided in division (F) of this section. A member may choose to purchase only part of the credit the member is eligible to purchase under this division in any one payment, subject to rules of the state teachers retirement board.
