Thank you, Mr. Chair.
Thank you to our witnesses for being here today.
Mr. Marshall, I'm going to probably direct most of my questions to you. I know Mr. Hoback knows this other industry very well, so I'll let him focus on that.
You talked about one of the greatest things that a country can do where mining's great as a whole procurement process. Talk to us a bit about what the tariffs are like for you guys right now to operate in some of these countries like Argentina and Brazil.
