OPTIONAL CASH BALANCE BENEFITS.

(a) Instead of the standard cash balance annuity payable under Section 820.053, a retiring member may elect to receive an optional cash balance annuity under this section.

(b) A person who selects an optional lifetime cash balance annuity must designate, before the selection becomes effective, one beneficiary to receive the annuity on the death of the person making the selection. A person who selects an optional cash balance annuity payable for a guaranteed period may designate, before or after retirement, one or more beneficiaries to receive the annuity on the death of the person making the selection.

(c) A person eligible to select an optional cash balance annuity under this section may select an option that provides that:

(1) after the retiree's death, the reduced annuity is payable in the same amount throughout the life of the beneficiary designated by the retiree before retirement;

(2) after the retiree's death, one-half of the reduced annuity is payable throughout the life of the beneficiary designated by the retiree before retirement;

(3) if the retiree dies before 60 monthly annuity payments have been made, the remainder of the 60 payments are payable to one or more beneficiaries or, if one does not exist, to the retiree's estate;

(4) if the retiree dies before 120 monthly annuity payments have been made, the remainder of the 120 payments are payable to one or more beneficiaries or, if one does not exist, to the retiree's estate; or

(5) after the retiree's death, three-fourths of the reduced annuity is payable throughout the life of the beneficiary designated by the retiree before retirement.

(d) If a beneficiary designated by a retiree under Subsection (b) predeceases the retiree and the retiree has elected an optional lifetime annuity, the reduced annuity shall be increased to the standard cash balance annuity that the retiree would have been entitled to receive if the retiree had not selected the optional annuity. The standard cash balance annuity shall be adjusted as appropriate for post-retirement increases in retirement benefits authorized by law since the date of retirement.

(e) Any increase in an annuity under Subsection (d) begins with the payment for the month following the month in which the designated beneficiary dies, and the increased annuity is payable to the retiree for the remainder of the retiree's life.

(f) The computation of an optional cash balance annuity must be made without regard to the gender of the annuitant or designated beneficiary.

(g) Except as provided by Section 814.008 or 820.0536, a person who selected an optional cash balance annuity described by Subsection (c)(1), (c)(2), or (c)(5) of this section may not change or revoke a beneficiary designation after the person's effective date of retirement.

(h) A beneficiary designation that names a former spouse as a beneficiary for a guaranteed optional cash balance annuity described by Subsection (c)(3) or (c)(4) is invalid unless the designation is made after the date of the divorce.

(i) An optional retirement annuity provided by this section is available to a member eligible to receive an enhanced service retirement annuity described by Section 820.053(a)(2)(B), but the same optional plan and beneficiary must be selected for the portion of the annuity payable from the law enforcement and custodial officer supplemental retirement fund and the portion payable from the member's individual account in the employees saving account.
