With respect to my final question, Mr. Diwan, you mentioned earlier that this is a discussion that should happen at the G8. I want to get Mr. Masters in on this as well.
The article in The Washington Post that our colleague Dan McTeague passed out talks about regulations being changed in terms of commodity exchanges. Also, they're allowing trading of energy commodities on private electronic platforms. Are those two specific items that the G8, or Canada and the U.S., have to look at? Are there other things specifically that the U.S., Canada, and other countries in the G8 have to look at?
