One of the determinants we've had in the past and that has driven costs has been the size of the file. The file has to be provided to all the parties in a particular case, so a lot of reproduction costs are involved.
In the corn case, as an example, we had to use both of our hearing rooms. The number of people involved was too large for us to be able to use only one hearing room. We had to rent some additional electronic equipment so that there would both a video and audio feed in the other room. Those kinds of things are extraordinary expenses. By and large, however, the hearing room is provided for because it's already in our facilities. The staff is already there. We just assign more or fewer people to a particular case.
If we have the unfortunate circumstance of having a large number of large cases all happening at the same time, then maybe we'll be a little bit thinner on the ground on the research side or in some other aspects of the case.
