Sure, Jim. We -- obviously, in our prepared remarks, we talked about some of the things that hit us specifically on the Water Solutions side. And certainly when you're doing work for a customer that includes a large portion of pass-through, that's going to have an impact on your margin. So we were, obviously, profitable on that incremental work to get the water transfer work, but we did have to pass through some water sources and some heating revenues. So that was a big part of what impacted us up in the Bakken. But I'd say, stepping back in more of a general response to, is it competitive pricing, is it cost? What is it? Activity levels? What we're seeing is there continues to be high demand for our assets and for our people, but we are, at the same time, trying to get pricing improvement, and that comes on a customer by customer basis and depending on which service lines, and which regions you're in, you'll have more success in some than others. And at the same time, though, we're fighting off our own price inflation. And so the key is just to try to stay a step ahead of that. But we -- obviously, we did see some deterioration in the fourth quarter, but believe that a meaningful amount of that was, I'll call it, short-term seasonality and some specific customer mix-driven items. But we do continue to believe that there are going to be opportunities to improve those margins. Over the longer term, it will be through things like adding technology that provide automation, but in the near term, it's hiring people such that we're not paying contractors, we're not paying as much overtime, that will help our cost structure. But also just taking best practices from both of these 2 companies that we brought together when you start to look at that down on a yard by yard level, we do think that there are opportunities there. And while we look at Q1, it's going to have some of its own challenges, but we actually do believe that where we're going to exit Q1 is going to be where we would've expected.
