So let me talk a little bit about the guidance we gave for Q2. So what we indicated in the script is, we do expect to see in Q2 engineered material volumes down 25% to 35% versus Q1. Now with that, about two thirds of that volume is still relatively sticky in terms of pricing, so we would expect those margins to maintain, possibly even get a little better as well as continue to go down. At the same time, you know about a third of it is tied to raws so we'll see those prices go down, margins generally stick around the same. For acetyls, we project the volume decline of 15% to 25% and Q2 from Q1, couple things around that, India lockdown, Southeast Asia lockdown, we're just not seeing the volume demand there. And margins they’re tend to follow, methanol and other things a bit. So probably expect to see our margins going down somewhat, but we would still expect acetyl margins in the mid teens or so. So we do expect some margin compression in AC, expect margins to be somewhere in EM but down with the volume. And if you look at what that just to maybe put some numbers around it. We saw a $25 million to $30 million hit in Q1 just from Asia. And Asia represents 20% of our overall business, and that was really in February and March. So consider that we've lost $10 million to $15 million per month on 20% of our business. It's not unreasonable to expect we would see a similar impact in Q2 on the other 80% of our business in the Western Hemisphere. So if you do the math on that, we do expect somewhere between $150 million to $250 million impact on Q2 EBIT, from the combination of volume and margin degradation. And how that -- as we go forward into Q3, Q4, we've done a lot of scenario planning, as I'm sure every company has, we think it's unlikely we're going to see a V-shape recovery. So coming back in Q3 that we do. We have done scenario planning around an U shape or L shape and broadly, expect Q3 to also be down but some recovery in Q4. But again, we don't really know how broad this is going to be. We don't know the degree of the downturn, nor do we know the duration and of course, Asia recovery, how fast that actually happens is a big factor.
