I think that's right. In this context, the challenge for Atomic Energy of Canada Limited is to try to provide the best guidance it can. They can't just say it's too complicated. They can't tell you when they're going to come back on. They obviously have to work on a critical path and try to discipline themselves to stick to a critical path. Also try to realize they're working fundamentally with money from the taxpayers and have to be very diligent about that.
At the same time, there are some risks, so quite often they've had to come back and say they have to revise that. They were really targeting and working hard to get it done by a certain date, but given the experience to date or given how much more difficult it's been than they had originally thought, they're adjusting to this new target. They're trying to keep that transparency because doctors and the international community, the other producers, need to understand where things are heading. I think we always encourage AECL, and in any kind of communication we certainly say there are risks around this. There's no certainty in this world for the reasons you're citing.
