(a)
If a basic death benefit becomes payable before the payment of the total amount the member elected to pay under any election with respect to normal contributions, arrears contributions, absences, or public service credit permitted under this part, the member’s entire compensation, or the service upon which that total amount was based, as the case may be, shall be included in the computation of the portion of the death benefit that is provided in subdivision (b) of Section 21532, and the unpaid balance of the total amount may not be paid to this system, nor may it be included in the member’s accumulated contributions that constitute a part of the basic death benefit.
(b)
Any balance of any total amount remaining unpaid at the death of the member on account of whom a special death benefit is payable or at the retirement of a member for industrial disability may be subject to Section 21037 when payment of the balance would not increase the allowance payable. When the balance of the amount remaining unpaid would increase the allowance payable, the balance shall become due and payable immediately, except that the survivor of a member who died under circumstances under which a special death benefit is payable and who had authorized payroll deductions may elect to continue those deductions from the survivor allowance in lieu of the lump-sum payment otherwise required. If the balance is not paid, the portion of the unpaid amount representing contributions on compensation earned in the membership applicable to the member at the time of injury resulting in death or disability shall be deducted from the benefit otherwise payable and this system shall be discharged from any liability for any annuity or benefit with respect to any remainder of the unpaid contribution.
(c)
Any balance of the total amount remaining unpaid at the time of retirement for service or ordinary disability, or at death, with respect to which a benefit is payable under Section 21546, may be subject to Section 21037 when payment of the balance would not increase the allowance payable. When the balance of the amount remaining unpaid would increase the allowance payable, the balance shall become due and payable immediately, except that the survivor of a member who died under circumstances under which a benefit under Section 21546 is payable and who had authorized payroll deductions may elect to continue those deductions from the survivor allowance in lieu of a lump-sum payment of the balance due. If the balance is not paid, the service credit included in the election shall be reduced proportionately and any service credit dependent on completion of payments eliminated for purposes of computing the allowance but not for purposes of determining entitlement to an allowance.
(d)
Notwithstanding any provision of subdivision (b) or (c), a member who retires before payment of the total amount which he or she elected to pay, may elect to pay the balance due, or the total amount if no payroll deductions had been made prior to retirement, by deductions from his or her retirement allowance equal to those which the member authorized as payroll deductions. In that case, service credit included in the election may not be reduced, nor may any prior service dependent on completion of payments be eliminated for purposes of computing the allowance. Any balance of the total amount remaining unpaid upon the death of the member shall be treated in the same manner as unpaid balances are treated if a special death benefit is payable, except that the survivor of a retired member who had authorized deductions from his or her retirement allowance in accordance with this subdivision, and who is eligible for a monthly allowance, may elect to continue those deductions from the survivor’s allowance in lieu of the lump-sum payment otherwise required.
(e)
Interest paid with respect to normal contributions, arrears contributions, absences, or public service credit permitted under this part, prior to date of retirement or death of the member, shall be credited to the member’s individual account. Interest paid after the date of retirement or death of the member shall be credited to the retirement fund pursuant to Section 20174.
