1. When a member is no longer employed by any employer in a position covered by the system, he shall thereupon cease to be a member of the system. Except as otherwise provided in sections 70.600 to 70.755, upon termination of his membership his credited service shall be forfeited by him. If such person is not a retirant and becomes reemployed by any employer in a position covered by the system, he shall again become a member of the system. Should such reemployment or employment occur within a period of four years from and after the date his membership last terminated, his credited service last forfeited by him shall be restored to his credit under the following conditions:
- (1) Any membership service or prior service for which he was required to make member contributions provided for in subsection 2 of section 70.705 shall be restored to his credit if he returns to the members deposit fund the amount, if any, he withdrew therefrom, together with regular interest from the date of withdrawal to the date of repayment;
- (2) Any membership service or prior service for which no member contributions were required as provided for in subsection 6 of section 70.705, or for which accumulated contributions were refunded as provided for in section 70.707, shall be restored to his credit.
- 2. Upon a member's retirement he shall thereupon cease to be a member and, except as otherwise provided in sections 70.600 to 70.760, he shall not again become a member of the system.
- 3. Should a former member entitled to a deferred allowance provided for in section 70.675 become employed in a position covered by the system before becoming a retirant, he shall thereupon cease to be entitled to a deferred allowance, and he shall become a member, with his previous credited service reactivated and to be increased by such employment.
- 4. Upon the retirement of a member whose credited service results from employment with more than one employer, the amount of his allowance shall be based upon his total credited service in force at the time of his retirement and his final average salary during such total credited service. Each such employer shall be responsible financially, within the provisions of sections 70.600 to 70.755, for the portion of such allowance based upon the service credited such member for employment with such employer, and the benefit program to be applied to each such portion of credited service shall be the benefit program such employer had in effect at the time the member left the employment of such employer.
- 5. If it is determined by the board at any time that continuous employment to time of retirement will leave a member with less than the minimum number of years of credited service specified in section 70.645, then upon such determination such member shall cease to be a member.
