We looked at that audit in 1999. At that point, the agency had put quite an effort into the underground economy, if my memory is right. There had been a number of people brought in specifically to deal with that.
I think our major conclusion was that it wasn't obvious to us. They weren't tracking the results, so it wasn't obvious whether those efforts were actually doing something. We were questioning whether all this effort had actually given something. In order to be able to know if the efforts that you're doing are having an effect, you have to have that kind of management information so that you know, well, maybe this approach is working better than others, so we'll concentrate here. Others may be not as efficient or as effective, and we'll stop doing that and do something else. It was that kind of management information, which they didn't have at that time.
