Certainly. As I mentioned, this is from a report that was done by an external consultancy. They looked at 324 oil royalty regimes and different parts of the royalty regime. In Alberta they looked at four or five, because there's old oil, new oil, third-tier oil. In the U.K. there's offshore, onshore. In the gulf coast, there are the same kinds of things. These rankings are an assessment by this consultant of the nature of the royalty regimes. If you are at the top of the list, that's the royalty regime that is taking the least amount for governments. If you're at the bottom, you're taking the greatest amount.
I've presented his view of different countries' takes of how much the government is taking in comparison to other countries. To be clear, this includes royalties and taxes, because this is really the only international comparison we have. It's not just the royalty regime.
Did you want me to comment specifically on the countries?
