Sure, Jo. Starting with refining, in the international markets, this is for bidding activity, we have very nice basket of opportunities in Asia and these projects are fairly large in the $5 million to $10 million value range and there's a few of those. So we see a nice basket of opportunities that are coming up in India, in Southeast Asia and also in China. China seems to be moving back toward a handful, a couple of refining projects a year starting to go ahead. We have those ideas, we're working on those early. We're involved in the early work on the India projects and we've been chasing some of the Southeast Asia projects and FEED and EPC bid for a couple of years and they're coming up to fruition now, it seems like. So we're feeling more enthusiastic about the outlook in the international markets for refining and this is principally new capacity commentary in international markets. So there's a very sizable amount of work that we've identified, we're participating in and feel generally pretty good about and the sales organization and engineering teams are doing the right things to get us in a position to have the right participation level and we believe the right success level for those projects. In Southeast, I'm sorry, Latin America, that's a slow period for us. There's not much going on there except for a couple of projects that will likely go ahead, but it's nothing like the identification of the project scope that we saw four or five years ago coming in Latin America, but there will be pockets of revamp and replacement to keep certain refineries up and running that have capital to do so. In the Middle East, we're not seeing anything readily right in front of us. That's more for purchase over the next two or three quarters, but there are some projects that are percolating for new capacity throughout the Middle East that we feel will participate on. Again, that's new capacity. And then in North America, I would say it's steady around revamp, debottleneck and the aftermarket elements of North America's refining base. So I generally feel, we generally feel good about the, of the oil refining outlook, both domestically and internationally, taking a longer term view or midterm view over the next couple of years. Petchem, the next wave is, the North America is sputtering along. By no measure is it as stout as the first wave. It's going to be more measured and coming not with the strong wave that we saw on the first wave. We won some of the work. We're bidding some of the other work that's coming up. I think that's going to be more of a periodic type of order environment than a steady flow and the international markets, I'd say that's comparatively steady versus the last couple of years for petchem and chem [indiscernible] yes.
