AUTHORITY TO PAY BENEFITS UNDER ALTERNATE FORMS

(a) The board of trustees may authorize the payment of the benefit that is due a recipient to be made as a lump sum or in another alternate form that is actuarially equivalent to the benefit that would otherwise be payable to the recipient at the time payments to the recipient would begin. An authorization under this subsection may be made as a policy of general application or may be made on a case-by-case basis considering the particular facts and circumstances. (b) Payment to a retiree in a lump sum or other alternate form may not be made without the retiree's consent if the payment is to be sent to an address in the United States and the present value of the retiree's benefit exceeds a minimum amount set by the board of trustees. A retiree who receives payment in a lump sum or other alternate form under this section continues as a retiree for purposes of a benefit provided by the subdivision under the optional group term life program. (c) Except as otherwise limited under Subsection (b), payment under this section is within the exclusive discretion of the board of trustees, and payment in a lump sum or other alternate form constitutes full satisfaction of the retirement benefit otherwise owed to the recipient. (d) The board of trustees may adopt rules for the administration of this section, including rules for the payment of benefits internationally and for the verification of a continuing right to receive payments.
