I think it's really been a function of the role that Canada has played globally, because we've not been a small player, we've been a big player. As a result of simply the amount of isotopes that Canada has provided, which has ranged over the years from somewhere between 50% and 30%, when we're out of the game, then that shortage plays back into Canada, and in fact it plays back into Canada more significantly than it plays back anywhere else.
