Each of the investigations takes a different length of time. There's no standard amount of time. We did an average of the four that we did, and we found that the average was about five and a half months, I believe.
As for the cost, we support our investigations almost entirely internally. We don't resort to outside lawyers, so it's quite a bit less expensive than if we were getting outside lawyers. The model we've developed for an average, because we knew we'd be asked this question, said that it was about $24,000 for the average investigation, I think, but there are enormous differences between each investigation.
