Project finance has spread worldwide and includes numerous industrial projects from power stations and waste-disposal plants to telecommunication facilities, bridges, tunnels, railway networks, and now also the building of hospitals, education facilities, government accommodation and tourist facilities. Despite financial assessment of PF projects being fundamental to the lender’s decision, there is little understanding of how the use of finance is perceived by individual stakeholders; why and how a financial assessment is performed; who should be involved; where and when it should be performed; what data should be used; and how financial assessments should be presented. Current uncertainty in financial markets makes many sponsors of construction project financings carefully consider bank liquidity, the higher cost of finance, and general uncertainty for demand. This has resulted in the postponement of a number of projects in certain industry sectors. Governments have seen tax receipts drastically reduced which has affected their ability to finance infrastructure projects, often irrespective of the perceived demand. Equity providers still seek to invest, however there are less opportunities due to market dislocation. Due to the demand for global infrastructure it is believed that project financings will return to their pre-crunch levels, or more so, however lenders’ liquidity costs will be passed on to the borrowers. Lenders will also be under stricter regulation both internally and externally.
