19 Tex. Admin. Code § 22.210
Upon request by an institution throughout the academic year, the Coordinating Board shall forward to each participating institution a portion of its allocation of funds for timely disbursement to students. Each institution shall have until the close of business on August 1, or the first working day thereafter if it falls on a weekend or holiday, to encumber program funds from their allocation. After that date, an institution may lose any funds in the current fiscal year not yet drawn down from the Coordinating Board for timely disbursement to students. Funds released in this manner in the first year of the biennium become available to the institution for use in the second year of the biennium. Funds released in this manner in the second year of the biennium are deemed returned to the Coordinating Board.
