It depends, because what's happening in the Arctic is a journey. We're seeing the beginning of what's happening. Right now we're talking of the Northwest Passage, but quite frankly, its a trans-polar issue; it is not the Northwest Passage, which as Canadians is something we need to be considering. It's north of Ellesmere Island, because that's the area that will be open as the ice starts to melt. So at some point, we see ourselves moving farther and farther north as the areas become open.
So I would say it will be a document in transition as to how we employ these ships, and each year we will look at how we will do it, based on ice conditions, etc. Obviously marine safety and security would be our number one issue.
