There'll be some uses. I mean, as you saw what we did on CUK here in Texarkana. So I mean, we're doing both. And maybe that's a great lead in Mark for me to just comment a little bit on all 3 substrates, just so that it's clear. I appreciate the question. When you look at what we're doing on CRB, we're going to have the lowest cost, highest quality CRB platform in North America by far. And we'll make a little over 1 million tons in terms of how that all kind of comes together. If you look at CUK now, what we're doing there, and you saw the growth that we've been able to generate on our CUK platform at roughly 3% CAGR for the last 12 years. Our global beverage franchise continues to grow so much so we're having to run, as we said, 90,000 tons on SBS right now, we're buying another 50,000 tons. So we're going to have now 3 mills that are capable of producing our high-quality low-cost CUK or our trademark name SUS. And that inflects about 150,000 of that 300,000 ton machine is already sold. We want to sell that to ourselves. And as we stated in our prepared comments, we've got a 95% integration rate on that machine. And if you just kind of do the math forward over the next few years, over the next 3 to 4 years max, our growth on CUK will actually approach 2 million tons. So that's one of the reasons why we needed to do that. And then what that leaves on our SBS platform, which right now is about 1.2 million in terms of total tonnage, it's about 900,000 tons. Of that 900,000 tons, roughly $400 million of that is our uncoated cup stock line. That's a highly integrated line, as we've talked about, roughly 85% of our production goes downstream into our cup plants. And then we'll have a coated material, which is about 500,000 tons. And for a business our size, that allows us to utilize that and also service our external customers, which are important. But we've got a clear path to drive our integration rates up towards that 80% range over the next 24 months. And that's -- when you think about how we're repositioning the business, I'd ask you to think about it in that context, it's really part of an overall approach to all 3 substrates for graphic packaging and our end use customers.
