(a) A vested employee is entitled to credited service for employment as a village public safety officer under the program established under AS 18.65.670 for which the employee has not otherwise received credited service under this plan. An employee is not entitled to credited service for employment as a village public safety officer unless the employee was employed as a village public safety officer for at least one year. The credited service claimed under this section may not exceed five years. Benefits are not payable on credited service for village public safety officer service under this section unless the employee makes retroactive contributions to the plan for the period of time that service credit is claimed.

(b) In order to obtain credited service under this section, an employee shall make an election to do so and shall verify the period of service as a village public safety officer. When eligibility for credited service for village public safety officer service has been established, an indebtedness shall be determined. The amount of the indebtedness is equal to the full actuarial cost of providing benefits based on the service as a village public safety officer. Interest as prescribed by regulation accrues on this indebtedness beginning on the date the actuarial cost is established. Any outstanding indebtedness that exists at the time a person is appointed to retirement necessitates an actuarial adjustment to the benefits payable based upon service as a village public safety officer.

(c) The credited service granted under this section may not be used to satisfy the credited service requirements for normal retirement.

(d) An employee is not entitled to credited service under this section if the employee is entitled to receive retirement benefits from another employer for the same service under a retirement plan that provides benefits based on defined benefits.
