Okay. Oswald, thank you very much. I'll take both of them, and I'm sure that Jessica would like to add on the first one. Let me start with the second one, though, Chemicals. Yes, absolutely. It is a cyclical business. We said we want to get that business in the shape, that it can still hold its head up at the bottom of the trough. I guess and I hope that we are at the bottom of the trough. It is pretty brutal, particularly in the east. And indeed, we do have difficulties keeping our assets fully utilized because significantly, demand is actually, in some cases, disappearing. And therefore, yes, I think we can consider this probably indeed at the bottom of the trough. We are losing money this quarter. You're absolutely right. It's not a massive amount, of course. And then it depends a little bit about what is considered the bottom of the trough. Is it this quarter? Is it this year? I think on average, we're doing more than somewhere between $2 billion to $2.5 billion a year. We do roughly 0 now. I would consider that sort of in line with where I expected that business to be. I think, indeed, Asia is probably the toughest because that is where most of the demand disruption temporarily happens. And of course, we run our Asia business predominantly on NAFTA-related feedstocks. Whereas in the U.S., we still have some benefit from the fact that also NGLs are really at a very low point, which, by the way, is then, of course, hurting as another part of the business. Let me say a few things about the numerical part that you had in the first question. I wish I could be as deterministic as you want our answer to be. It really isn't -- you look forward, and you see that at this point in time, of course, we are in very tough conditions. It's not just the oil price, but it's also gas prices that are significantly lower and disconnected. LNG prices, NGL prices are significantly lower. Refining margins are actually weak, and we're very weak in Q4. And Chemicals, we just talked about. So in that type of setting, you just know that you have to take a more prudent approach. You think $1 billion is roughly right. We will scale that up if we see that we have more breathing space. But there is no further sort of scientific magic to it to figure out what is the right number. We will have to go on that on a quarter-by-quarter basis. Jessica?
