Texas Government Code - GOV'T § 854.404. Conditions for Benefits

(a) Supplemental disability benefits payable from the supplemental disability benefits fund cease on the death of the disability retiree and are, except as provided by this subchapter, subject to the same terms of issuance as are standard disability retirement benefits.  The suspension or discontinuance of a disability retirement annuity automatically suspends or discontinues, as applicable, a supplemental disability retirement annuity based on the same service.

(b) The board of trustees may reduce proportionally all supplemental disability benefits payable from the supplemental benefits fund at any time and for a period that the board finds necessary to prevent payments from the fund in a year from exceeding available assets in the fund in that year.
