Risk identification and allocation is a key component of project finance. A project may be subject to a number of technical, environmental, economic and political risks, particularly in developing countries and emerging markets. Financial institutions and project sponsors may conclude that the risks inherent in project development and operation are unacceptable (unfinanceable). "Several long-term contracts such as construction, supply, off-take and concession agreements, along with a variety of joint-ownership structures are used to align incentives and deter opportunistic behaviour by any party involved in the project." The patterns of implementation are sometimes referred to as "project delivery methods." The financing of these projects must be distributed among multiple parties, so as to distribute the risk associated with the project while simultaneously ensuring profits for each party involved. In designing such risk-allocation mechanisms, it is more difficult to address the risks of developing countries' infrastructure markets as their markets involve higher risks.
