I don't have an exact figure on it, but from some of the earlier testimony here we can see that certainly when you have a finished product, you're going to get a higher value for that. I referred earlier to the issue of staples production. Of course these are highly capital-intensive projects. One of the downsides of this is that the shareholders want a return on this. What tends to happen quite often in staples-based economies is that the impetus to pay off the shareholders means that you start to produce higher quantities of whatever the staple is at the expense of that value added. You try in a sense to increase the amount of money coming in through the sheer volume of the product as opposed to limiting the size and the amount of the product but raising the value that you're actually getting from it.
One of the things we're seeing with the pressures to export bitumen is that so much money has gone into oil sands development to increase the sheer volume of product that to now pay it off you have to find a way to get it out of here. We don't have the capacity for processing, but we're going to keep shipping larger and larger amounts hoping that doing so will pay off in a gross amount of money. I think that's the dynamic that is actually pushing this.
