I have a very quick comment. Thank you.
That gets to the heart of the “rotationality” of our officers abroad. Generally speaking, we have been focusing on geting people to extend a little bit longer, so that in what I would call the A markets--the U.S., Japan, and western Europe--we're looking at a normal tenure of about four years. It was never really less than four years, but in some hardship postings it was as low as two. The business community told us that was just unreasonable, so now we're in a normal process of extending to at least three years or even longer. It's because we've changed our foreign service directives to financially help the people to look at doing these kinds of things. Our last two officers in Nigeria have both extended, for three years and four years. I don't have the figures in front of me, but I think, anecdotally, I'd say that the average length of postings has been extended greatly on the trade side.
