Thank you, Mr. Chair.
Thank you, Mr. Casey, and Mr. Kirke, for being with us today.
Maybe, Mr. Kirke, I'll start with you and follow up on your recent comment. You said you hope that as a policy we proceed with a rules-based trading system. I'm wondering if you could explain a bit more what you mean by that. Is there anything specific about the way our negotiations are being conducted that would cause you to have concern in that regard?
