Well, the base idea for that is that we use peer-reviewed literature—that type of literature—and then you have a better feel that whatever information has come out of it has been looked at in an objective way. You start with that business first, and then there's the next part of that. Sometimes that's not available, and then it's just about having a transparent process. Everyone lays out on the table what they know and what they have in a transparent way and they allow others to look at that. Sometimes you do have to go that way.
