There were some key points to this. I could go on for 30 minutes too, but I'll keep it to 30 seconds.
First of all, the pricing of compliance costs requires certainty for business planning. If you don't know what the price is, you don't know how to input that into your business model.
Secondly, the diminishing access to offsets assumes a certain amount of technological innovation, which, again, is uncertain. We don't know that some of the stuff that everybody is hoping is going to work is going to work. What we do know, at least in those two examples, is that our U.S. competitors simply don't face this issue right now. They may, in which case the field may level, but we don't know that, and uncertainty is the worst thing you can do to a business.
