At the time the qualifying business enters into a revitalization agreement, it may make, with the approval of council, an irrevocable assignment of future payments attributable to the job development credit made pursuant to this chapter to the designated trustee. For purposes of this chapter, "designated trustee" means the single financial institution designated by the council to receive all assignments of payments made pursuant to this chapter and to the terms of an agreement entered into by the qualifying business. If a qualifying business elects to assign payments to the designated trustee, the election must be made on a form provided by the department, including a waiver of confidentiality pursuant to Section 12-54-240, and the payments may be paid only to the designated trustee.
