Sure. This is John. Let me answer your question regarding the demand capacity first. Our demand model, it still remains the same as what we communicated at the last Lithium Day. So, just simply put, we think that the overall market is growing at about 20,000 metric tons per year through the 2020 time period. The total market is about 185,000, 190,000 metric tons. So, we've seen that demand forecast play out. We are updating that demand forecast, and we'll communicate that at the Investor Day in the first quarter. With regard to long-term agreements and how did that impact our ability to price product, of course, we are having those critical conversations with customers where we do need the flexibility to adjust price, but we want to treat customers fairly. So, there are provisions in our agreements that allow us to adjust price as appropriate and also gives the customer an opportunity to look at the market if they so choose to do that. But I think the important thing is that we're committing these long-term agreements, allow the customers to invest in the energy storage market because they know that they have a partnership with a company like Albemarle that has the ability to invest to supply them. And I think as Luke outlined in the opening comments, when we said during the Lithium Day that the overall market's growing at 20,000 metric tons per year and we're going to invest to supply half of that, I think you've seen through the tolling, through the acquisition of the China conversion technology, the expansion of our mine in Australia, what we're doing in Chile, how we're expanding the capacity in Chile, that we have invested and will continue to invest to be able to supply at least 10,000 metric tons per year. We've done it this year. We'll do it next year. And I think we've given you guys the path to see that we can deliver on our promises. And that is going a long way with the customers. I mean, as I said, we have very long and deep relationships with these customers. They appreciate it. They appreciate being with a market leader like Albemarle, and we're going to treat each other fairly going forward.
