Refunding bonds. Bond anticipation notes

(a) Any bonds issued by the authority under sections 15-31c to 15-31f, inclusive, and at any time outstanding may at any time be refunded by the authority by the issuance of its refunding bonds in such amounts as the authority may deem necessary, but not exceeding an amount sufficient to refund the principal of the bonds to be so refunded, any unpaid interest thereon and any premiums, related termination payments and commissions necessary to be paid in connection therewith and to pay costs and expenses which the authority may deem necessary or advantageous in connection with the authorization, sale and issuance of refunding bonds. Any such refunding may be effected whether the bonds to be refunded shall have matured or shall thereafter mature. All refunding bonds issued hereunder shall be payable and shall be subject to and may be secured in accordance with the provisions of section 15-31c. (b) Whenever the authority has adopted a resolution authorizing bonds pursuant to section 15-31c, the authority may, pending the issue of such bonds, issue temporary notes and any renewals thereof in anticipation of the proceeds from the sale of such bonds, which notes and any renewals thereof shall be designated “Bond Anticipation Notes”. Such portion of the proceeds from the sale of such bonds as may be so required shall be applied to the payment of the principal of and interest on any such bond anticipation notes which have been issued. The principal of and interest on any bond anticipation notes issued pursuant to this subsection may be repaid from pledged revenues or other receipts, funds or moneys pledged to the repayment of the bonds in anticipation of which the bond anticipation notes are issued, to the extent not paid from the proceeds of renewals thereof or of the bonds.
