On the production side, the remaining 20% to 30% depends on the nature of the upgrader. If it's integrated with a refinery, then actually there's no loss in reheating of the fuel, so it's a smaller percentage, but I don't have the exact number for you. I would guess it's probably about a third, but that's just a guess. I can get you the scientific information.
