We have looked at some ways of increasing efficiencies. Certainly composite grading is one. Instead of grading each car that's coming in, grade them in car lots of 10, 15, 20, or whatever--in different sizes. That would create significant savings. We have also talked with the industry about doing a rough grade, highlighting some of the key factors and providing more detail at a later date.
We haven't moved on any of those initiatives because we haven't received industry support for them, but there are some things that can be looked at. Certainly the review that is under way right now is looking at some other broader initiatives, as well.
