The sale of equity in other infrastructure projects, mainly concession contracts rather than PPPs, has also been increasing, particularly in transport (airports and ports) and energy (wind farms and grids).
Toll road projects have been a feature of PPP programmes in Spain, Italy, Australia and Latin America and account for 74% of projects in which equity has been sold. Hospitals and prisons each account for 4% of equity transactions followed by schools and government offices each with 3%. Defence, airports and rail or rapid transit each account for 2% and miscellaneous group of projects accounting for the remaining 8% per cent of projects.
