Laurence, I apologize, I don't have a precise and clear answer. I've always been a bit of a believer that you've got to control your supply chain. You've got to control the cost in the supply chain. We've looked internally multiple times of looking at having -- in Aerospace division, Automotive division, a construction division, have all of our product flow into that one division. I don't know, and there are a lot of our competitors that seemingly every 2 or 3 years they kind of pencil in back and forth. I think that those opportunities, particularly as we look at construction in auto, which is 60% plus of our overall business, we try to capitalize on relationships and applications and so forth. But if you've got an application that’s going into a coding application on a car and a product going into the seat on a car, quite frankly most car manufacturers don't tie the two together. And they’re not going to pay you anymore, or treat any better because you're supplying with paint, you're supplying with foam, and you're supplying with wiring cable. I think you lose some of that efficiency of just looking at the supply chain, looking at your working capital, looking at your technology transfer [indiscernible] and keeping an eye on benzene, down through nitro-benzene, analene, MDI, the formulations systems and so forth, keeping an eye on that entire line, rather than being modeled into what we're doing in an end-market. But you really have to, in my opinion, walk and chew gum at the same time, you've got to be able to look for those opportunities, but I just don't think that they’re as prevalent as they usually are. Building materials might be -- we've continued to experiment with that, as we look at what we're doing with spray foam and how that might overlap with some of the applications in OSP, and how that might overlap with some of the rigid foam. We're already in all three of those, we’re market leaders in all three of those. To the extent that we can find consolidation and opportunity, we’ll certainly be doing it. But again, you look at the customer base regionally, it just varies from company to company and contractor to contractor and state to state, to be honest with you. So I think we'd rather be focused on a very targeted approach rather than a macro approach.
