Texas Government Code - GOV'T § 1232.115. Expenses Included in Principal Amount

(a) The principal amount of obligations may include amounts required to pay required reserve funds, capitalized interest, the authority's administrative costs, issuing expenses, and other expenses associated with the authority's issuance and sale of the obligations.

(b) The principal amount of obligations issued to finance the purchase of computer equipment that is the subject of a contingent appropriation under Subchapter B,  1 Chapter 317, must be sufficient to cover any payments of principal and interest that must occur during the remainder of the biennium after the obligations are issued.

(c) Because of the expenses specified by Subsection (a) and because the cost estimates for acquisition, construction, repair, or renovation of a project cannot be finally determined at the time the project is authorized for financing, the principal amount of any issuance of obligations may be an amount not to exceed 150 percent of the amount of the estimated cost for the project being financed.

(d) Costs and expenses authorized by this section may not be included in the principal amount unless the board finds that those costs and expenses are necessary and reasonable at the time the obligations are issued.
