(2) Except as provided in subsection (3) of this section, an inactive member ceases to be a member of the system if the member is not vested and is inactive for a period of five consecutive years.
(3) A school district employee does not cease to be a member of the system under subsection (2) of this section if:
(a) After completing a school year, the member is inactive for the next following five school years; and
(b) The member either is reemployed by a school district in a qualifying position at the beginning of the sixth school year, or reaches earliest service retirement age before the beginning of the sixth school year.
(4) Interest shall not accrue on the amount in the member account of the former member from the date that membership is terminated under subsection (2) of this section. Upon request by the former member, the Public Employees Retirement Board shall pay the amount in a member account to a former member upon the termination of the membership of the former member under subsection (2) of this section if the former member is separated from all service with employers who are treated as part of a participating public employer’s controlled group under the federal laws and rules governing the status of the system and the Public Employees Retirement Fund as a qualified governmental retirement plan and trust. The board may deduct, from the amount paid to a former member under this subsection, all reasonable costs incurred by the system in locating the member.
