Maybe Mark can answer some of it.
The fact is that statistics show that with more vehicles being built in Mexico, they're not getting their aluminum from.... I don't know where they're sourcing their materials. I think a lot of it is from offshore. They've now surpassed Canada by more than a million cars. I think you're right that the North American content in those vehicles is something we should have at our fingertips if you're going to a GM plant or a Ford plant.
My experience has been that, because our organization uses North-American-built cars, I can tell you that it's very difficult to find a North American car with 50% North American content, and that's an issue.
Mark may have something to add.
