I don't know that I could speak to licensing in the Beaufort. What I can speak to is that we have a very high level of co-operation and collaboration with the Americans in the Arctic through the Arctic Coast Guard Forum that I mentioned previously, but also bilaterally. For example, we do on-water live training with D17, which is based out of Juneau, Alaska. We also are working with the Americans on a project. It goes by different names, but the idea is to create safe, low-impact corridors throughout the Arctic.
I could get into this in more detail if you wish, but the idea is to essentially shrink the geography by investing more heavily where we know the ships are actually going. We're working with the Americans on that. Then with respect to American passages through our waters, they co-operate with us just as every other country does.
