I don't recall, but I imagine they are fairly expensive to use. The difficulty that I've had in trying to think that through is that since I never know how many investigations there are going to be in any one, two, or three years, it's hard to staff up and do it all internally. So we try to deal with it internally to the extent we can. When we need outside help, we get it.
