C.R.S.
Section 24-75-908
Execution of notes
(1)
The notes shall be signed on behalf of the state by the state treasurer and countersigned by the controller, and the seal of the state treasurer shall be affixed thereto; except that no such signatures or seal shall be required if the notes are issued in book entry form pursuant to section 24-75-907 (1). The resolution authorizing the issuance of the notes may provide that the notes may be authenticated prior to delivery by the authorized representative of the registrar, paying agent, or depository.(2)
Pursuant to article 55 of title 11, C.R.S., any signature required by subsection (1) of this section may be a facsimile signature imprinted, engraved, stamped, or otherwise placed on the notes. If all signatures of public officials on the notes are facsimile signatures, provision shall be made for a manual authenticating signature on the notes by or on behalf of a designated authenticating agent. If an official ceases to hold office before delivery of the notes signed by such official, the signature or facsimile signature of the official is nevertheless valid and sufficient for all purposes. A facsimile of the seal of the state treasurer may be imprinted, engraved, stamped, or otherwise placed on the notes.
