One way to ask your question is to ask if P3s are a failure. Our answer is that, no, they are not a failure. There are some hair-raising experiences along the way, but we are in a process of learning here and we're experimenting here. We as a country are learning things as we go through the exercise of trying different things around P3s, so for us the really important thing is, as was somewhat indicated in my comments, what we have learned and what we are going to do differently as we go into the future. It's in this vein that we look at the experiences to date. We say there are some failures and some successes, and I've talked about those learnings.
I think we all agree that the original experience of P3s hasn't lived up to the expectations that had been hoped for at the time, but we are gaining that experience and, as we've all said, if we can establish a long-term infrastructure plan that has that sense of long-term stability about it, then P3s become one of the tools that can be really helpful, given the right conditions and the local capacity to make the decisions they need to make.
