Yes. So let me take a stab at that, let's sort of break it into two pieces. The first is around volumes and continued demand. I have to say, and this really starts in Europe and we're about 40% of our value-added now is going into these low-carbon products. We're seeing more and more pull. And you can see this, for example, with some of the automotive customers where they've set some pretty aggressive targets to be able to drive to net carbon - net-zero carbon, but we also see it in, for example, electric cables and a number of different places. And so I have to say, as we progress, and I'm probably been asked this question every single quarter for the last couple years, I am becoming more and more optimistic that those volumes are going to continue to improve and we're seeing that really take root in Europe and starting to see that in North America as well. And of course, there's a lot of connections between our customers in North America and Europe so that it tends to spillover. So, certainly, seeing good volume improvements and particularly going to continue to see those volume improvements, because we've got a lot of ongoing conversations with customers. On the realizable value, so the important thing here for us is that because we've, for the most part, turned to renewable energy, a lot of these sales right now are cost free, right? It's a matter of making sure that we have the right power source. Of course, there's all the work that goes into being a responsible producer and making sure that we can line up to the Aluminum Stewardship Initiative so that we can prove our credentials. But most importantly, this is essentially driving towards the scarcity or the fact that there is a differentiated product with less carbon content inside of our products. And so it's cost free. On the premium side, and you can see some of the published indices, which I think are pretty representative of the kind of premiums that we're getting, tends to range between $25 and $50 now, which is a beginning. It is certainly not where we see this continuing to go. And I would also argue, look at our low-carbon sales, EcoLum is a very good example of that, which is our low-carbon aluminum. Look at this as sort of the first step to making sure that our market is prepared for zero-carbon aluminum down the road. For our ELYSIS metal we want it to be very clear, the unique properties, the unique characteristics and the fact that this will be truly a differentiated product. And so really this is sowing the seeds that does create value for us in the short term, but more importantly, will be the seeds that will be significantly greater value down the road.
