Dr. Kilby, I just want to move on to another topic if I could. You addressed an earlier question concerning the possibility of drugs in larger quantities being shipped to a developing country and coming back. In your mind, you see that as a very low risk. I did hear you say, though, that one possibility or concern was drugs leaking across borders on the African continent, for example. So could you just tell us a bit more about that and why you're concerned about that? Ultimately, the purpose of this mechanism and these drugs is for humanitarian purposes and not for commercial purposes or to be diverted. So could you speak a little about that?
