Build–operate–transfer (BOT) or build–own–operate–transfer (BOOT) is a form of project financing, wherein a private entity receives a concession from the private or public sector to finance, design, construct, and operate a facility stated in the concession contract. This enables the project proponent to recover its investment, operating and maintenance expenses in the project.
Due to the long-term nature of the arrangement, the fees are usually raised during the concession period. The rate of increase is often tied to a combination of internal and external variables, allowing the proponent to reach a satisfactory internal rate of return for its investment.
BOO (build, own, operate) is a public-private partnership (PPP) project model in which a private organization builds, owns and operates some facility or structure with some degree of encouragement from the government. Although the government doesn’t provide direct funding in this model, it may offer other financial incentives such as tax-exempt status. The developer owns and operates the facility independently.
