Well, we hired an expert in demographics, and we've also done some detailed work with the registry of Indian status. So we're now a bit more comfortable with that number, but it's certainly not the final figure. As you mentioned, people who have lost status in the past.... 1951 was quite a long time ago. Over that period people have lost touch, and when they read about the decision and start hearing about it again, they may revive their interest in becoming Indians. We know only about the people who are actually in the registry right now, and we can take a guess about their children, who may not be Indians in the registry, but we still have information about them. We can use that for the demographic information. But for the people who are further remote, it's harder to say. We've been working away on estimates of that.
