If no designation has been made, or the death of the designated person occurs prior to the death of the member and another designation has not been made, the proceeds shall be paid to the persons surviving at the death of the member in the following order of precedence:
First, to the spouse of the member;
Second, if no surviving spouse, to the children of the member and descendants of deceased children, per stirpes;
Third, if none of the above, to the parents of the member;
Fourth, if none of the above, to the duly appointed executor or administrator of the estate of the member;
Fifth, if none of the above, to other next of kin of the member entitled under the laws of the domicile of the member at the time of his death.
The retirement allowance payable hereunder to a qualifying survivor shall be the annual amount which when added to the compensation payable under the Virginia Workers' Compensation Act for the death of the member equals 50 percent of the member's average final compensation if the survivor does not qualify for death benefits under the provisions of the Social Security Act in effect on the date of the death of the member. If the survivor qualifies for death benefits under the provisions of the Social Security Act in effect on the date of the death of the member, the allowance payable from the retirement system when added to the compensation payable under the Virginia Workers' Compensation Act shall equal thirty-three and one-third percent of the member's average final compensation.
Any beneficiary entitled to the entire amount of a retirement allowance under the provisions of this subsection as a result of the death of a member shall be entitled to waive his rights to the allowance by written notification to the Board within ninety days after the death of the member in order to make available a retirement allowance under the provisions of subsection B of this section.
