Thank you, Kathryn. So if we focus on the two most recent acquisitions, because at this point, the InterWrap acquisition which we did in 2016 has been kind of fully integrated into our Roofing business and our Components business, and now is a part of our ongoing discussion of our Components business, which we say growth at double digit revenue and operating margin similar to our Roofing business. So obviously, that continues to be very good business for us inside the company. With Pittsburgh Corning, which we now refer to as our Foamglas business, we characterize that business as a business that had about $240 million of revenue on a historical basis, and had adjusted EBITDA margins of kind of 25% to 27%. So on a go forward basis, we had given the expectation that we would expect to see relatively flat revenue in that business, because some of the markets, we are seeing good progress and good growth. One of the critical markets for Pittsburgh Corning, which is the liquefied natural gas market, we know is going through bit of a downturn. We are beginning to see projects coming through the pipeline, and so we are excited to see growth coming out past 2018. But as we head into 2018, we'd expect a continuation of that kind of revenue rate, that kind of margin rate, and then some synergy capture, where we expected about $20 million of synergy capture by the middle of 2019. So I think that helps you frame out Pittsburgh Corning, and I think in our disclosure, we said Foamglas contributed about $60 million of revenue for the fourth quarter and about $5 million of EBIT. So that's specific to the quarter. Paroc, we said about $500 million of revenue on an annual basis or $100 million of EBITDA, on an annual basis and about $50 million of adjusted EBIT on an annual basis. We have a fair amount of purchase accounting, so as we think, that's pretty cash rich EBIT, unlike some of the other situations, where our DA is very -- somewhat capital intensive. In this case, we do have a fair amount of accounting that's going to drop the $100 million of EBITDA down to $50 million of EBIT. So it's a little bit better contributor than that. In terms of cash flow, we will see effectively 11-12 of that this year, because we closed on February 5. And we have said, we have expected a little less than $20 million, about €15 million of synergies on that deal by the end of 2019.
