The Department of Transportation’s Office of Inspector General has announced that it is undertaking an audit of transportation-related public-private partnerships.
DOT-OIG says the objectives of the audit are to:
Determine the cost advantages and disadvantages to the public sector of PPP transactions compared to the more traditional financing of transportation infrastructure projects through the issuance of debt by government or quasi-government entities in the public or municipal bond markets;
Evaluate the benefits and value realized through PPPs to both the private and public sector in order to determine the overall equity of the transactions; and
Determine whether, and to what extent, PPPs result in operating efficiencies.
