1. For purposes of this section:

 a. (1) “Eligible qualified service” means service as a member of a city fire retirement system or police retirement system operating under chapter 411 prior to January 1, 1992, for which service was not eligible to be transferred to this system pursuant to section 97A.17.

 (2) “Eligible qualified service” under this paragraph “a” does not include service if the receipt of credit for such service would result in the member receiving a retirement benefit under more than one retirement plan for the same period of service.
 b. “Permissive service credit” means credit that will be recognized by the retirement system for purposes of calculating a member’s benefit, for which the member did not previously receive service credit in the retirement system, and for which the member voluntarily contributes to the retirement system the amount required by the retirement system, not in excess of the amount necessary to fund the benefit attributable to such service.

Terms Used In Iowa Code 97A.10

 2. An active member of the system may make contributions to the system to purchase up to the maximum amount of permissive service credit for eligible qualified service as determined by the system, pursuant to Internal Revenue Code section 415(n) and the requirements of this section. A member seeking to purchase permissive service credit pursuant to this section shall file a written application along with appropriate documentation with the department by July 1, 2011.
 3. A member making contributions for a purchase of permissive service credit for eligible qualified service under this section shall make contributions in an amount equal to the actuarial cost of the permissive service credit purchase, less an amount equal to the member’s contributions under chapter 411 for the period of eligible qualified service together with interest at a rate determined by the board of trustees. For purposes of this subsection, the actuarial cost of the permissive service credit purchase is an amount determined by the system in accordance with actuarial tables, as reported to the system by the system’s actuary, which reflects the actuarial cost necessary to fund an increased retirement allowance resulting from the purchase of permissive service credit.
