(B) For each year or portion of a year of service credit restored under section 3307.71 or 3309.26 of the Revised Code, a member shall pay to the public employees retirement system the amount certified by the former retirement system plus interest at a rate specified by the former retirement system under section 3307.712 or 3309.262 of the Revised Code for the period during which deductions are made under section 145.294 of the Revised Code.

(C) The public employees retirement board shall at least annually transmit to the former retirement system notice and any payments made to restore service credit under section 3307.71 or 3309.26 of the Revised Code.  The former retirement system shall restore the service credit for the year or portion of a year for which the payment was made.
