We've been looking at this issue for our industry for some time. We did make some proposals to U.S. customs, but they have to work within the framework of the rules that are there and they weren't able to accommodate our changes. We do have some ideas for a more generic approach to dealing with our particular industry but also some specific ideas for rules that relate to transformation of products, so that when you mix two products together, you move them into a different tariff category. That would apply to movement of heavy oil from the oil sands, if you add light oil to it to make it lighter so it moves in the pipelines.
