(1) If a participant dies prior to the receipt of the DROP benefit pursuant to 19-9-1208, the participant's surviving spouse or dependent child is entitled to receive a lump-sum payment equal to the participant's DROP benefit as of the date of the member's death and the benefit the surviving spouse or dependent child would have received under 19-9-804 had the member retired rather than elected to participate in the DROP.
(2) If there is no surviving spouse or dependent child, the designated beneficiary is entitled to receive a lump-sum payment equal to the participant's DROP benefit as of the date of the member's death and the member's accumulated contributions minus any benefits paid from the member's account, including monthly DROP payments.
(3) The benefit paid pursuant to this section must include interest credited to the participant's account as follows:
(a) through June 30, 2009, interest must be credited every fiscal yearend at a rate reflecting the retirement system's annual investment earnings for the applicable fiscal year;
(b) after June 30, 2009, interest must be credited every fiscal yearend at the actuarially assumed rate of return. Proportionate interest must be credited for distributions taking place at other than a fiscal yearend.
