If a member ceases to be an employee, except by death or retirement under the provisions of this Chapter, he shall be paid such part of the amount of the accumulated contributions standing to the credit of his individual account in the annuity savings fund as he shall demand. If a member dies before retirement, the amount of his accumulated contributions standing to the credit of his individual account shall be paid to his estate or to such person as he shall have nominated by written designation, duly executed and filed with the board of trustees. If an employee returns to membership in the system after withdrawing his contributions, he may repay the amount which he withdrew, plus interest at a rate determined by the board of trustees, and upon such repayment, he shall again be given credit for the service he forfeited at the time he withdrew.
