Section 67.798 - Bonds - issuance, interest, payments - income tax exemption1. Bonds issued pursuant to sections 67.792 to 67.798 shall be issued pursuant to a resolution adopted by the board of directors of the district which shall set out the estimated cost to the directors of the district of the proposed improvements, and shall further set out the* amount of bonds to be issued, their purpose or purposes, their date or dates, denomination or denominations, rate or rates of interest, time or times of payment, both of principal and of interest, place or places of payment and all other details in connection with such bonds. Any such bonds may be subject to such provision for redemption prior to maturity, with or without premium, and at such times and upon such conditions as may be provided by the resolution.2. Notwithstanding the provisions of section 108.170, such bonds shall bear interest at such rate or rates determined by the district and shall mature within a period not exceeding twenty years and may be sold at public or private sale for not less than ninety-five percent of the principal amount of such bonds. Bonds issued by the district shall possess all of the qualities of negotiable instruments pursuant to the laws of this state.3. Such bonds may be payable to bearer, may be registered or coupon bonds and if payable to bearer, may contain such registration provisions as to either principal and interest, or principal only, as may be provided in the resolution authorizing such bonds, which resolution may also provide for the exchange of registered and coupon bonds. Such bonds and any coupons attached to such bonds shall be signed in such manner and by such officers of the district as may be provided by the resolution authorizing such bonds. The district may provide for the replacement of any bond which has become mutilated, destroyed or lost.4. Bonds issued by the district shall be payable as to principal, interest and redemption premium, if any, out of all or any part of the recreation fund, including revenues derived from annual property taxes. Neither the board members nor any person executing the bonds shall be personally liable on such bonds by reason of the issuance of such bonds. Bonds issued pursuant to this section shall not constitute a debt, liability or obligation of this state, or any political subdivision of this state other than the issuing district, nor shall any such obligations be a pledge of the faith and credit of this state, but shall be payable solely from the revenues and assets held by the district. The issuance of bonds pursuant to this section shall not directly, indirectly or contingently obligate this state or any political subdivision of this state other than the issuing district, or the district, to levy any form of taxation for such bonds or to make any appropriation for their payment. Each obligation or bond issued pursuant to this section shall contain on its face a statement to the effect that the district shall not be obligated to pay such bond nor the interest on such bond except from the revenues received by the district or assets of the district lawfully pledged for such district, and that neither the faith and credit nor the taxing power of this state or of any political subdivision of this state other than the issuing district is pledged to the payment of the principal of, or the interest on, such obligation or bond. The proceeds of such bonds shall be disbursed in such manner and pursuant to such restrictions as the district may provide in the resolution authorizing the issuance of such bonds.5. The district may issue negotiable refunding bonds for the purpose of refunding, extending or unifying the whole or any part of such bonds then outstanding, or any bonds, notes or other obligations issued by any other public agency, public body or political subdivision in connection with any facilities to be acquired, leased or subleased by the district, which refunding bonds shall not exceed the amount necessary to refund the principal of the outstanding bonds to be refunded and the accrued interest on such bonds to the date of such refunding, together with any redemption premium, amounts necessary to establish reserve and escrow funds and all costs and expenses incurred in connection with the refunding. The board shall provide for the payment of interest and principal of such refunding bonds in the same manner as was provided for the payment of interest and principal of the bonds refunded.6. In the event that any of the board members or officers of the district whose signatures appear on any bonds or coupons shall cease to be on the board before the delivery of such bonds, such signatures shall remain valid and sufficient for all purposes, the same as if such board members or officers had remained in office until such delivery.7. The district is hereby declared to be performing a public function and bonds of the district are declared to be issued for an essential public and governmental purpose and, accordingly, interest on such bonds and income from such bonds shall be exempt from income taxation by this state.
