The other thing about risk assessments is that they're living documents in a way, and we are able to look at new work that's being done. As I said before, we did look at trade. We didn't have a lot of information, so we have a lot less certainty associated with our rankings of trade. In continuing to better understand trade and movement, and in looking at enforcement activities, we could then have greater certainty, and we could say more positively what our assessment of that is.
It just depends on whether or not managers wish us to re-evaluate the risk assessment. This was our second one. We did one in 2005. It is something that is a living document and can be looked at over time.
