Yes. I think we do -- I think it's all in the above. I think if we picked anyone of those elements and that was the only element than we probably wouldn't have the performance -- the sustainable performance that we enjoy today and expect it when we bought the business. RBI is the combination of a couple of businesses. In terms of renewable energy on one side and conservation with the greenhouse initiative on the other side, and that's what we report. And by and large, not a lot of material differences in terms of relative performances. So it's not like one is dragging the other up dramatically on a given day. So that is different operationally. And it provides additional benefits in terms of the back-end side of the business. The front-end, it gives us couple of different markets to work in, in terms of two different rep types of rising tides. But the back-end, it also gives us an opportunity to leverage similar, so this is like finance and HR, the typical overhead ones, but also the operational size of making and buying products. So that -- I would think that would be unique business model relative to our typical competitors in the solar industry. On the front-end, we're also different. We don't target, a lot of our competitors would be heavier weighted than we would be in larger scale projects, where we primarily have historically focused with fixed-tilt and small-scale community solar and average size of it couple of megawatts. Introduction of our tracker system, by and large, is small-scale as well is much bigger than our fixed-tilt. It's probably up 5 or 6 megawatts, but that's just by the nature of the product. Whereas most of our competitors -- and we do it with a broader value proposition because we're smaller scale. We do design work in terms of the size, we do engineering work in terms of solar testing. We do manufacturing design, structural design work and then we do the manufacturing. In a high percentage of the jobs, we do the actual install because we own our own pile drivers. When you get into large-scale projects, that were primarily driven by tracker only, they are more material-only jobs, which -- when it sells to tighter margin profiles and obviously, much higher volumes. But -- and I would say, the last piece is on the back-end, we manufactured some of the key elements in terms of the 81 items on the structural side that may be a lot of our competitors with third-party outsource for their own reasons at around price, service and quality, but the -- so I think the combination of all those things makes us uniquely different, and I think it results in the margin profile that you see today, that's a lot more sustainable going forward and what we expected when we bought the business.
