Yeah, maybe if I could maybe try and help on that David a little bit as well. So if you look first to second quarter, I think you're right, we normally do expect margins to the upper or flat out from the first quarter. And what we had as Rich indicated in his remarks, first to second quarter while revenue was up probably up a little less than what we had anticipated. And then on the EBIT line a couple factors at play, we did have a higher amount of distributor price adjustments, which again, we got it to 150 bps of pricing, still expect that, but some of the adjustments can vary quarter to quarter and they're a little more than normal. In the second quarter, which was a factor, particularly in Process, that's all Process, we took a lot of inventory out sequentially, as I mentioned, 20 million sequentially, from first to second, that was an impact on margin sequentially, as well and then obviously with Diamond Chain coming in a little bit slow on it. Again, I think that had a little bit of a negative impact as well. And a lot of that did hit on the Process side of the house. And as Rich said, as we looked at the mix in the second quarter and then the run rates et cetera, we felt the second quarter was a good base to carry into the rest of the year. And then again, on the guide, it really was two components, it was adjusting the margins, if you will, from what we guided a quarter ago on the total company and then layering in a normal decremental if you will on the revenue guy down, which would be if he had to split it probably in the two thirds to one third split you look at that full year EBIT change at the midpoint.
