Maybe I'll start that one, because I would like to make one point here. That's not in any way, shape, or form to say that we do not understand the concerns of industry around this very complicated area, and the frustration. I accept that, but the statements concerning coercion on the part of the department and that kind of thing are entirely unfounded, totally spurious, and we don't accept those at all.
Certainly we're still working with industry on collaborative arrangements, and we look forward to having no doubt quite a heated dialogue, to some extent, on the policy framework, and where we're at, and where we're going more broadly.
I'll ask Bill or Kevin to answer the more specific questions.
