I think it's true that it's very difficult to estimate the future costs. You should ask Joel Lexchin and Marc-André Gagnon these questions. They picked a representative sample of current drugs and estimated how many days the entry of generics would be delayed based on those two changes that I referred to previously. You should ask Industry Canada and Health Canada for their analysis of those changes as well.
