The fundamental cause, I guess, was that they didn't have the appropriate permit. The volume that was brought in was above the low-tariff volume, but the two organizations didn't make sure that what was imported did not actually exceed the volumes that were permitted to be imported. Again, it was an issue of not identifying that more was coming in than should have been coming in under a permit, and because more was coming in, that should have had the higher rate of tariff. They weren't monitoring that.
As I said, I think that earlier on, part of that problem was that the information existed in two different systems in two different departments, and they weren't periodically bringing that information together to identify that this was happening. I think that's something that they very much need to do.
