Cal. Public Utilities Code § 130422

(a) The bonds shall bear interest at a rate or rates not exceeding the maximum allowable by law, payable semiannually, except that the first interest payable on the bonds or any series thereof may be for any period not exceeding one year as determined by the commission. (b) In the resolution or resolutions providing for the issuance of the bonds, the commission may also provide for call and redemption of the bonds prior to maturity at such times and prices and upon such other terms as it may specify, provided that no bond shall be subject to call or redemption prior to maturity unless it contains a recital to that effect or unless a statement to that effect is printed thereon. (c) The principal of and interest on the bonds shall be payable in lawful money of the United States at the office of the treasurer of the County of Orange or at such other place or places as may be designated, or at either place or places at the option of the holders of the bonds. (d) The bonds, or each series thereof, shall be dated and numbered consecutively and shall be signed by the chairman or vice chairman of the commission and the auditor-controller of the County of Orange, and the official seal of the commission attached. The interest coupons of such bonds shall be signed by the auditor-controller of the County of Orange. All of the signatures and seal may be printed, lithographed, or mechanically reproduced, except that one of the signatures on the bonds shall be manually affixed. If any officer whose signature appears on bonds or coupons ceases to be such an officer before the delivery of the bonds, the officer’s signature is as effective as if the officer had remained in office.
