Yes. So I will tell you that the mix impact is across all aspects of the business. It's through our acquisitions, it's through our businesses in Europe – the U.K., Europe/Rest of the World segment, it's in our residential in both wholesale and retail. So, it is a strategy that is all consuming across the company, and of course in the non-residential space as well. So, we've had some – if I think about this year, we didn't talk specifically about it, but we've had a number of new product development in the non-residential space with regards to some of our core activities, which are the material that go inside the door. Because we are so backward integrated, it's been an interesting opportunity for our team in Chicago to develop some new materials. And then, from an STC perspective, the sound transmission, we've offered a bunch of new products this year in working with sound attenuation type products, which is becoming a big issue, at least a big expectation, whether it's hospitals or hotels, and how do they redeem sound in the buildings and between rooms. There is a lot of recent research that shows that patients will actually heal better and faster and it will be cheaper for the hospitals if their sound attenuation is better in the rooms. So, there is actually a cost benefit to them buying more expensive doors. So, that's an example. And then of course, the Harring acquisition was, earlier this year I guess it was December of last year which we didn't speak to specifically in the call earlier, but those high end style and rail doors are a big opportunity for us to grow, and quite frankly the growth rate of those products has been terrific. It's a relatively small business. But I don't have the numbers in front of me, we can share them at some point, but that growth has been extremely high. One of the highest growing parts of our business on a standalone basis. And then lastly, as Larry spoke, it's about the speed, I mean, the whole focus is speed to market, something that we were just okay at. I think with the acquisition of USA Wood Door and trying to drive that further in the business and start to look at doing that in more areas, will really help the business be more effective.
