That's correct.
One of the differences between bitumen and synthetic crude oil is called the light-heavy differential, and this number actually bounces around quite a bit on market factors. The numbers you see there were done back in about 2008 based upon market prices. Since then the differential has narrowed down, but it's widening back out again, so these numbers depend upon market factors that are there. The doubling is based upon about a 50% difference in heavy and light prices. Right now we're sitting at about 30%, so you can sort of factor that in there.
The $25 billion in petrochemicals was based upon three different studies we've done in conjunction with the Government of Alberta that said if we now take these byproducts and move them up the chain, what will the net value be? They identified a number of different opportunities. There would be feedstock advantage, and the consultants' estimates were that the value of these petrochemicals would be $25 billion annually.
