I presume you're also talking about the upgrading and refining into higher-value products. We do quite a bit of that, but that is a much more complex question because there are issues of being close to market. I only highlight it at the very upstream end. Just to give you a couple of outlines, the world oil price is $100 today, but we are only getting $90 here in North America. The world price for natural gas is above $9 per thousand cubic feet; we, in Canada, are only getting $3.50 or maybe $4, generally speaking. These are all a consequence of lack of diversity of markets.
Whether or not we should be adding value by processing and refining further, that is a much more complicated question that I can't answer.
