34 Tex. Admin. Code § 77.1
If a member of the Judicial Retirement System of Texas Plan One who is eligible to select a death benefit plan dies prior to age 65, the annuity will be reduced by the factors developed by the actuaries. Those factors are adopted by reference and are made a part of this section for all purposes. Copies of the factors may be obtained from the executive director of the Employees Retirement System of Texas at 200 E. 18th Street; P.O. Box 13207, Austin, Texas 78711-3207. The reduction factors that apply to deaths of members prior to age 65 and that occur on or after September 1, 2009, are those factors adopted by the board on February 24, 2009, based on assumptions adopted by the board on May 13, 2008. For deaths occurring prior to September 1, 2009, the previously adopted factors apply.
