Right. So, yeah, there were a few things that came into that. One was we had a little bit of mixed shifts. So we pulled, and interestingly, we pulled a lot of the higher margin deliveries out of Q2 and the Q1 on an incremental basis towards the end of the quarter, which we're always striving to close as many homes as we can and try to get those behind us, and this time the mix worked out in our favor where we had some pickup on that side. The can rate was a pretty important factor for us as well, where we didn't have to resell homes that had already been in our backlog at healthy margins and we didn't have to quickly discount those homes to get them sold in the quarter. So, that helped us incrementally. And we've been really, as far as the forecasts go, that's always a difficult one to forecast out. So, we did, I will say, as we were forecasting the 21% for the first quarter anticipated a can rate similar to what we'd seen in the prior two quarters and had a little bit tucked away on that increment. So, those were the main drivers. We like to be -- we like being up. When you look at it sequentially, we're really based in the second quarter predominantly up what's in our backlog, and we really saw sort of a tick up in some of those incentives and whatnot back in those times when those sales were booked and they're coming through. And the final thing and it's always the same, and I know everyone hates hearing it, including me oftentimes, but mix plays a big part of this, between communities, high margin, low margin communities, between regions and between divisions. So all of those factors sort of come together in that. And if you're plus or minus a percent quarter-over-quarter-over-quarter for the most part it kind of reflects an operation that's running pretty smoothly. You're pulling your deliveries from your backlog. You're not seeing many cancellations. You're not having many -- much pressure on you to resell homes and close them in the current quarter due to cancellations and we really liked the steady environment that we saw in the first quarter, it was a really nice start to the year for us and we're looking forward to the rest of the year as a result of that, particularly, selling through the spring.
