Good morning, everyone. As I characterize the last year, we recognize that challenges, particularly from our met segment have led to a lack of consistency and result, a consistency to both you and we rightly came to expect. We would note that the met coal segment continues to be challenged in part due to asset quality we have long acknowledged this middle of the road, and we continue to work to upgrade. Shoal Creek has been a great addition to the portfolio and more needs to be done. As we move through the call, we will discuss actions underway to address these issues. On the other hand here is what Peabody has delivered. Our U.S. operations continue to generate cash flows many times that of our CapEx, even with the industry backdrop. Our seaborne thermal operations are highly profitable, even as higher domestic obligations have pressured export volumes. And we put nearly $4 billion into investments in the business, liability reduction and shareholder returns in the last 2.5 years. Against that broader backdrop, let's look at the quarter in more detail beginning on Slide 4. Third quarter revenues totaled $1.11 billion, down 22% from the prior year, reflecting reduced net coal volumes and $90 million in lower pricing, excluding the impact of higher financial revenues. As expected, DD&A in the third quarter declined $28 million versus the prior year from Portfolio changes and lower contract amortization. We also reduced SG&A by 17% to approximately $32 million on a decline in personnel costs. Other items to note include $8 million in legal expenses related to the PRB Colorado joint venture, as well as the $20 million impairment charge associated with the Wildcat Hills mine in the Illinois Basin. Earnings from equity affiliates reflects a loss of approximately $21 million related to the independently operated Middlemount joint venture after the highwall failure in late June. These impacts resulted in a loss from continuing operations net of income taxes at $74 million and a loss per share of $0.77. Adjusted EBITDA totaled $150 million for the quarter compared to $372 million in the prior year, with the largest factor related to the decline of more than $300 million in revenue on lower pricing and volume. Let's take a closer look at operating performance starting with our Seaborne Thermal segment. In line with expectations seaborne and thermal volumes picked up quarter over quarter increasing to 3 million tons of export thermal sales at an average realized price of $72.24 per short term. Higher quality Newcastle volumes represented 74% of the mix and accounted for favorable realizations even as Newcastle spec prompt pricing moved below the 10 year average. The segment generated third quarter adjusted EBITDA of $77 million despite some $60 million of lower pricing. Margins for Seaborne Thermal totaled 31% underpinned by a strong cost performance at both the Wambo Underground and Wilpinjong Mine. Within met coal results, sales were impacted by customer driven deferrals and a lack of production from North Goonyella. Third quarter shipments totaled 1.8 eight million tons at average realizations of 1294 per ton. Lower volumes, along with higher ratios at the Coppabella Mine and an extended longwall move at Metropolitan Mine resulted in elevated met coal cost of 113.63 per tonne excluding North North Goonyella. In addition lower yields and conveyor downtime followed by subsequent upgrades led to elevated costs at Shoal Creek. Within U.S. Thermal, adjusting EBITDA of $153 million was largely in line with the prior year as cost improvements in the PRB and Midwest offset the impact of lower pricing and volume. The PRB achieved cost per ton of $8.69, a multi-year low. That's 4% below prior year and 12% lower than the first half of 2019. This led to PRB margins of 21% during the quarter, and. Levels that continue to be the best in the basin and again this year. In the Western segment, adjusted EBITDA increased $18 million versus the prior year, on strong performance from Twentymile and increased revenues associated with customer funding for post mining costs at Kayenta.. Even with a 14% reduction in sales volumes, the Midwest delivered adjusted EBITDA in line with the prior year as margins increased over - both over the previous quarter and 2018 levels. On Slide five. Free cash flow totaled $92 million, driven by operating cash flows of. $176 million and CapEx at $86 million. At the quarter end, cash and cash equivalents totaled $759 million with continued healthy liquidity levels of $1.35 billion. We remain committed to ensuring financial strength, and we've taken considerable steps to ensure that stream. And we believe we have a balance sheet that is well positioned for volatility inherent to the mining industry. Year-to-date, cash return to shareholders has been largely balanced between buybacks and dividend. Share repurchases accelerated in the third quarter relative to the second totaling $144 million. As a result, Peabody's share count has been reduced by 30% since our listing to about 97 million shares today. We remain committed to shareholder returns as a basic tenant of our investor appeal, understanding that modest deleveraging and reduced coal pricing moderate our near-term cash flow generation. Our balance sheet is strong. Our cash level is high. Liquidity has only increased since last quarter. And our reduction in liabilities has nearly matched our substantial shareholder returns in the past 10 quarters, which by themselves nearly total our entire market cap. Turning to Slide 6. We are updating our full year guidance ranges for a number of items. Starting with our Seaborne and Thermal export volumes. We now expect about 11.5 to 12 million tons for 2019 on increase required domestic shipments. This reflects the lower end of the initial range we gave at the beginning of the year. Our cost guidance remains unchanged. Met coal sales for the full year are now expected to be between 8.5 million ton and 9 million ton. This reflects the softer PCI spot market, as well as production challenges. We've seen some recent interesting pricing dynamics between imported and domestic coal in China and are keeping a close eye on the arbitrage between December and January pricing and we'll defer volumes if it's economically rational. As a result, we anticipate full year met coal cost of about $100 per ton. In the U.S., we have tightened our ranges for PRB volumes and lower Midwest volume. The midpoint of our PRB volume guidance remains at 110 million tons, reflecting strong third quarter in October shipments. Given the events of the summer, the majority of shipments for the remainder of the year represent lower quality coal per customer request. In the Midwest, we are now expecting volumes of about 60 million tons due to production declines at several mines on lower customer requirements along with negotiated deferrals. We have lowered the higher end of our overall U.S. cost guidance and now expect cost to be between $1,395 and $1,445 per ton. We also continue to refined our capital requirements and are reducing our 2019 CapEx range to $300 million to $325 million. Fourth quarter adjusted EBITDA is expected to be lower than the third quarter, primarily as a result of the closure of the Kayenta Mine, which contributed $30 million in the quarter. We also expect higher volumes across multiple segments, an increase in required Australian domestic thermal shipments and lower pricing to impact results. Looking ahead to next year, about 75% of our PRB volumes are now committed for 2020. Current mine plans show increasing volumes of higher BTU coal in 2020 than in 2019. We continue to have a strong contracted position in the Midwest. We have about 13 million tons of Midwest volumes priced for 2020 and an average of $39 per ton, with some 11 million tons priced at a similar level for 2021. This reduced volume reflects portfolio changes made during 2019, as well as an already fully priced book for 2020. In a basin with significant swings in export demand, we see this committed position as a significant competitive strength. From seaborne perspective, we are now anticipating closure of Millennium in early 2020 as we've been quite successful at highwall mining which is continue to extend its life by multiple months. We are anticipating some 900,000 tons to be sold this year from Millennium. And we've also extended the life of our seaborne thermal open-cut operations through both the Wilpinjong extension and United Wambo JV and therefore we would expect similar volumes as 2019. Let's now look at the industry fundamentals that have been at play, beginning on slide 7. Recently, we've seen a rebounding - we've seen a rebounding in met prices, following a 20% decline in the average prices from the second to the third quarter of 2019. Chinese met coal imports remained strong with August marking a new monthly met coal import record of more than 9 million tons. We expect the pricing spread between domestic Chinese coking coal and imports to create tension with import restrictions and incentivize imports as we move into the New Year. In addition, rising India met coal imports are projected to maintain momentum on growing steel needs, which India is unable to source at home. Growth in met exports by Australia, Russia and Mongolia have been muted by declining U.S, shipments. And as we look ahead, capital investment in both metallurgical and thermal coal has declined in recent years as coal use continues to rise. From 2011 through 2013, a $154 billion of capital investment was deployed by major coal producing regions. In the last three years, only $72 billion was deployed, representing less than half the capital that was invested during the last peak cycle. Moving to seaborne thermal, prices have lifted from their September lows in recent weeks. As expected, ASEAN import demand continues to drive seaborne thermal growth. Vietnam imports have more than doubled year-to-date through September. China and India continue to show strength with imports rising some 20 million tons. On the supply front, both U.S. and Colombian exports have declined sharply through August in response to unfavorable netback pricing. And as we look ahead, we would expect ASEAN countries to continue to offset declines in Atlantic demand over time as urbanization and new coal fuel capacity creates greater need for imports. It's no coincidence that Peabody is positioned in Australia as we expect it to serve these growing demand centers. Glenn?
