Public Private Partnerships for Transport Infrastructure
Renegotiation and Economic Outcomes
Public-private partnerships (PPPs) are an important vehicle for private participation in infrastructure investment, delivery and management. Renegotiations are an integral part of the PPP process but their prevalence varies markedly in different parts of the world. Renegotiations can be usefully employed to adjust the PPP contract to unforeseeable events, beyond the control of contractual parties. There is also a danger, however, that they will be used to change the initial balance of costs and benefits in the contract.
The purpose of this report was to provide an overview of the nature of PPP renegotiations in different regions of the world and at different times to help understand when PPP contract renegotiations are desirable and when they are not. In general it is concluded that when contracts are set up well, renegotiations should be few and far between.

Executive summary
International Transport Forum
Public-Private Partnerships (PPPs) are complex financing structures involving substantial transaction costs, with the legal documentation alone often consisting of several hundred pages. Despite the care taken in preparing PPPs, renegotiation is a common occurrence and can have an impact on value for money. It is not clear, however, whether this reflects the impossibility of any contract to foresee every eventuality or is usually the result of more mundane explanations.
