Yes. Thanks John and morning, Chris. Maybe I refer you to slide number eight, our Q3 segment results. I'll just make a couple of comments there. If you look at the gross profit on a year-over-year basis, there was a $200,000 increase. The rail segment saw about $1 million increase in gross profit, 140 basis points sequential -- year-over-year deterioration. That was largely driven by product mix a little -- I'd say, more so product mix than inflationary costs impacting the business within rail for that year-over-year comparison. And as John indicated, the rail segment actually from a sequential basis point of view was pretty flat in terms of gross profit percent, from Q2 to Q3. So, I mean, that shows that we were able to manage the overall business and maintain gross profit percent, despite those supply chain headwinds that we've been facing. On the infrastructure side, a little more of a deterioration that you can see on a year-over-year basis, with the revenue up $1.7 million. Gross margin dollars were down $800,000. On a basis point of view, it was 180 basis points. You recall the issue that we have on our Coatings and Measurement business was about a 390 basis point year-over-year decline in gross profit in Coatings and Measurement specifically. And I think the Coatings and Measurement gross profit decline in the quarter was $1.3 million. So you can see the balance of the business was higher, on a year-over-year basis, along with the sales revenue, which we're pretty pleased with, but we continue to have that headwind in Coatings and Measurement. And then the last thing, I would say is, if you just think about the year-to-date results over on slide number 9, we have an $18.8 million increase in revenue, but a $6 million decline in gross profit. If you flip to the next page, you'll see that, the margins in the rail business are doing pretty well on a year-over-year basis down 40 basis points year-over-year, but nice revenue growth. But the key takeaway there is our Coatings and Measurement business, its revenue is down about $27 million, $28 million year-over-year with a margin decline of $12 million. So I mean, it's pretty clear to see that, the year-over-year impact on a year-to-date basis is driven by Coatings and Measurement. And we're continuing to monitor that business to make sure we maintain cash neutrality here in the short-term to see what the recovery looks like.
