Rather than mandating a certain amount of refining capacity or refinement of our own crude oil, I think the level of intervention we would like to see is one that would address the accountability issue. We could go further if necessary, but I would say the first step, as a minimum, is to understand where inventories are, because that is where the rubber hits the road. Without a knowledge of the industry by consumers and their representatives, there is no understanding at all of what is happening out there and when we're going to be hit with a price spike or a shortage. So that's as a minimum.
You can go further than that. You can mandate minimum operating inventories. You can say they can't go below that, and if they do, you have to take action. That would be a more interventionist step, for example.
You could go even further. Various steps increase the level of intervention, but I would say, as a minimum, knowing what inventories are is a relatively straightforward approach, we think.
