What we do is we set a national risk-based inspection cycle for the program validation inspections. Those are implemented on a planned basis, cyclically. Those are the big inspections that cover a lot of elements of a company.
Then we have triggers for a whole series of other kinds of process inspections and other types of inspections, some of which are similar to the traditional inspections. Of those other types of activities, some are unannounced. But again, that's something that...whether it's appropriate to the particular decision at the point in time of making the plan between the manager and the inspector to go out and do an inspection. There may be a reason to do this unannounced.
I just was making the point that typically these would be generally a plan in the sense that you have a national annual plan, then you break that down into weekly and monthly plans at the inspector level, and the managers do a little bit of planning around that. I just wanted to make sure that people were clear that we don't necessarily see a lot of reason for unplanned inspections, but sometimes you use unannounced.
