Ryan, while we don't prognosticate going forward, as I look at the fourth quarter, the spike increases of cost were a little north of $20 million. These are very discrete items that we track. And we just didn't see those increases really in Q3 anywhere near to the extent that we did. So, when I look at our business and really try to understand the very elements of your question, I believe that 200 bps of margin degradation, because of these spiked costs, we will recapture these. If I look at the price mix, which was probably a 280 bps drag on margins compared to the year ago period. Again, we’re seeing -- we continue to see that, if you will, price degradation, but we also see a shift in products to, if you will, lower-priced substitutions. And it doesn't mean that they're less effective. It doesn't mean that we make less margin. It just may mean that we make less margin dollars around that. Having said all of that, I believe that the price increases will have an influence on that price mix as well, as we go into the market. So confidence level of trying to understand where we are and then the base going forward, our view is that 2019 will see growth in dollar terms, driven by, again, price increases. We're assuming that the economic environment continues to be favorable. Again, our customer base gives us pretty solid input that while they have record backlogs, yes, they're a little concerned about releases of larger products, they still see the notion of stock and flow in those types of projects being favorable. So, we have a positive, yet cautiously optimistic view coming into 2019. And we're pretty good at extracting margin as volumes improve. So as I mentioned, mix does have an impact on our business. Mix did have an impact this quarter. When we look at our C&I business, we don't look at it as a business, but we look at the C&I channel. Typically, that's north of 60% of our total revenues. Well, it declined this quarter because the revenue growth in other aspects of our business, whether it be electrical distribution channel, the home center channel, the infrastructure and utility channel, our enterprise solutions, which are really selling our Atrius-based luminaires, those are the folks that brought us the lift and larger projects were left behind, if you will. So, we are optimistic that these larger projects will continue to come back, and that adds spice to our margin stew, if you will, because the variable contribution off of those more complicated projects are favorable to us.
