I'm not aware of any specific mandate on geographic selection in areas. What I can say to you is that our policies, our guidance, and our advice to departments is to sit down and think holistically about the whole picture, which would encompass such questions as where you're going to train people and where the mix is.
There is certainly a level of reflection and responsibility to decision-making at the departmental level, but we wouldn't have a list of specific criteria. As a central agency we're offering broad policy guidance, and because the regime shift was to give ownership and to get the whole leadership in a department doing this, they really do have the responsibility. They're accountable for how that department runs.
