The reserve is $550,000. As I say, only in one case--in this fiscal year, not last fiscal year--have we actually taken a trip in connection with an investigation. But it could happen that we need to do a certain amount of travel. It depends on the investigation. It could be more complex than anything we've done so far.
So that's the sort of thing we want to cover. Denise can give you some of the other reasons for the reserve.
