That's a good question. I can't remember what the background was for it. I think the focus, we thought, was to try to encourage more private capital to come in to ensure that the projects being done would be sustainable and would be profitable, and we were concerned about subsidies. We thought that was the best approach. I think P3s are good, but that was the priority.
The other comment, as I mentioned, is that we also believed brownfield sales would be good. Where there's a utility or an operation that's already moving, do you sell part of that off to the private sector to get capital and then use the proceeds of that to invest in other infrastructure? That was kind of the line.
I think, again, Michael Sabia and Mark Wiseman would be better positioned to answer that than I am.
