Credit Support and Infrastructure Investment: The Case of the Transportation Infrastructure Finance and Innovation Act (TIFIA) Program

The Impact of Accessing Public Credit Support on P3s project will measure the impact of credit support program application and approval processes on project delivery. Public Private Partnerships (P3s) often rely on the Transportation Infrastructure Finance and Innovation Act (TIFIA) credit program, as well as state-level credit support programs, as part of their financial structure. On the one hand, TIFIA can provide invaluable credit support to a project because it charges low interest compared to other credit sources and is subordinate to other loans so long as a project is not in default. However, a protracted process for securing public credit support may adversely affect project delivery by delaying financial close. We propose to study the effects of this process through desk research and a series of confidential interviews with public and private sector actors in the P3 industry. This interview data would focus on the impacts to the public sector and the concessionaire related to securing public credit support.
