‘Finance’ or ‘financing’ includes the issue of bonds by a county for the purpose of using substantially all of the proceeds to pay (or to reimburse the obligor or its designee) for the costs of acquiring, improving and equipping a project, whether these costs are incurred by the county, the obligor or a designee of the obligor. Title to or in such project may at all times remain in the obligor or the obligor’s designee or assignee and, in such case, the bonds of the county shall be secured by a pledge of one or more notes, debentures, bonds or other secured or unsecured debt obligations of the obligor.
