Certainly, and I think the aluminum issue is one that has become a bit distorted in some of the discussion.
As I mentioned before, we did issue a new requirement that doesn't exist now, that 70% of purchases by manufacturers of aluminum be of North American origin. On top of that, we have much more North American content required according to the rules of origin for autos, so there's much less room to use foreign inputs than there has been in the past, which is also going to create significantly more of an incentive to purchase aluminum from North American sources.
With respect to the difference between steel and aluminum, after seven years steel will be treated somewhat differently because of its melted-and-poured requirement. That requirement will not apply to aluminum. There's a 10-year review of aluminum to see whether it requires a similar type of process. We have already had discussions with the U.S., and with Mexico, to talk about how, if there is a pattern of aluminum imports into North America from China or from other countries undercutting the North American market, we will have the opportunity to revisit that issue and see whether aluminum does require the same treatment as steel.
There's no requirement for us to wait the 10 years to address that issue. We can address it as soon as we start to see a problem.
