If a retirant dies before he or she has received, in straight life pension payments, an aggregate amount equal to his or her accumulated contributions standing to his or her credit in the Members Deposit Fund at the time of his or her retirement, the difference between his or her accumulated contributions and the aggregate amount of pension payments received by him or her shall be paid to such person or persons as he or she nominated by written designation duly executed and filed with the Board of Trustees. If no such person or persons survive the retirant, such difference, if any, shall be paid to his or her legal representative. No benefits shall be paid under this section on account of the death of a retirant if he or she elected Option A or B provided for in Section 297.16.
