I don't have the precise numbers. We could work to see if we could get an estimate. I think it may be difficult to go back in time and find out exactly what has happened, because it was part of some person's job and now they've moved. As I said, they're spending more time on safety issues, where they were spending more time on approval issues.
But if the committee would like, we could put some effort into trying to determine what we're spending now and what we were spending then.
