Thanks, John. So with the first quarter behind us, we can confidently reaffirm what we stated in the last quarter. 2024 has already demonstrated a reversal of several trends from the last 18 months and we anticipate the recovery to continue. On the market, we've already begun to see an uptick in TiO2 demand that is indicative of what we would see on the front end of a recovery. On pricing, we expect TiO2 pricing to reverse its downward trend and improve as we move through the remainder of 2024. Regarding zircon, volumes continue to improve from the trough levels realized in July of 2023, and there was a significant improvement in the first quarter. Further recovery will be somewhat reliant on China given its significant share of the overall zircon market. Nevertheless, demand has rebounded even in the absence of a major shift in China. On the operational side, we incurred significant cost in 2023 in the range of $25 million to $35 million per quarter from running our assets at lower utilization rates due to soft market demand. At the end of 2023, we began increasing our operating rates in line with the demand improvements we were beginning to see in the market, which has and will continue to have a positive impact on our manufacturing costs. Although we still have some high-cost inventory to move to the business, with sales outpacing our previous guidance, our EBITDA margins will now be in the range of 20% this quarter. We will continue to deploy technology at our sites to reduce costs and improve efficiencies, which will also benefit our cost position as we ramp up. And we're investing in key capital projects to sustain our vertical integration. From a growth perspective, our R&D efforts remain focused on product and process innovations to enhance profitability. Additionally, we're continuing to explore opportunities in the rare earth space. Moving to Slide 11. I'll now review 2 key capital projects in more detail. As a reminder, this year we're investing approximately $130 million in 2 key mining projects in South Africa to replace our existing mines reaching end of life. These projects are critical to continuing our vertical integration strategy and are important to pursue now to ensure a smooth transition to replace existing mines reaching end of life. These investments will maintain our more than $300 per ton advantage relative to market pricing for feedstock, and our very high return projects with internal rates of return in excess of 30%. Turning to Slide 12. I'll review our outlook for the quarter and year ahead in more detail. For Q2, we expect TiO2 volumes to increase between 7% and 10% and zircon volumes to remain relatively flat, both compared to the first quarter. And we expect TiO2 pricing to increase slightly versus the first quarter. As a result, we're expecting Q2 2024 adjusted EBITDA to be $160 million to $180 million and adjusted EBITDA margins to be in the range of 20%. Our expectations for 2024 cash uses are as follows. Our capital expenditures are expected to be approximately $395 million. Our net cash taxes are expected to be less than $10 million as the significant capital expenditures in South Africa are deductible. Our net cash interest expense is expected to be $140 million, and we're expecting working capital to be a tailwind. The magnitude of the cash flow will depend on how significant the market recovery is as we move through the year. Our capital allocation strategy remains largely unchanged. We are prioritizing investments in the business that are critical to furthering our strategy and driving value from our vertically integrated portfolio. And even at this investment level, we expect to generate positive free cash flow for the full year. We will also be focused on bolstering our liquidity. And as the market recovers, we'll look to resume debt paydown. We will continue to prioritize our dividend. And finally, we will continue to evaluate strategic high-growth opportunities as they arise. Currently, we're focusing on the rare earth space. And we will keep the market updated on any key developments as they arise. That concludes our prepared comments. We'll now move to the Q&A portion of our call, so I'll hand the call back over to the operator to facilitate. Operator?
