Okay. I think that would be useful.
You've stressed the fact that sometimes a P3 is good and sometimes a P3 isn't good. Could you tell us, with concrete examples or criteria, the types of situations where it's not good? I can think of traditional areas where P3s are often used, such as for highways, bridges, and hospitals, and maybe even prisons—although that would be controversial—airports.... Is it a question of scale and complexity?
