Texas Health and Safety Code - HEALTH & SAFETY § 772.529. Refunding Bonds

(a) A district may issue bonds to refund all or any part of the district's outstanding bonds, including matured and unpaid interest coupons.

(b) Refunding bonds shall mature serially or otherwise, as determined by the board, not more than 25 years after the bonds' date of issuance. Bonds shall bear interest at any rate permitted by state law.

(c) Refunding bonds may be payable from the same source as the bonds being refunded or from other sources.

(d) Refunding bonds must be approved by the attorney general in the same manner as the district's other bonds. The comptroller shall register the refunding bonds on the surrender and cancellation of the bonds being refunded.

(e) A resolution authorizing the issuance of refunding bonds may provide that the bonds be sold and the proceeds deposited in a place at which the bonds being refunded are payable, in which case the refunding bonds may be issued before the cancellation of the bonds being refunded. If refunding bonds are issued before cancellation of the other bonds, an amount sufficient to pay the principal of the bonds being refunded and interest on those bonds accruing to the bonds' maturity dates or option dates, if the bonds have been duly called for payment before maturity according to the bonds' terms, must be deposited in the place at which the bonds being refunded are payable. The comptroller shall register the refunding bonds without the surrender and cancellation of the bonds being refunded.

(f) A refunding may be accomplished in one or more installment deliveries. Refunding bonds and the bonds' interest coupons are investment securities under Chapter 8, Business & Commerce Code.

(g) Instead of the method set forth in Subsections (a)-(f), a district may refund bonds, notes, or other obligations as provided by the general laws of this state.
