(a) If a member reinstates from service retirement under this part, payment of a retirement annuity based on the balance of credits that was transferred from the member’s Defined Benefit Supplement account to the Annuitant Reserve shall terminate.

(b) If the member subsequently retires again, an annuity or lump-sum payment based on the remaining balance of credits in the member’s Defined Benefit Supplement account at the time of the subsequent retirement shall become payable pursuant to Section 24202.5 and the balance of credits in the member’s Defined Benefit Supplement account shall be transferred to the Annuitant Reserve or paid to the member in the form of a lump-sum payment.
