Thank you, Tiffany, and good morning all. NRP continues to operate under CDC guidelines and company pandemic work protocols. I am pleased to report that our business continues to improve, as the global economy recovers from the pandemic-induced shock that began last year. Demand for metallurgical coal, thermal coal and soda ash is strong and prices for those commodities have increased significantly since the beginning of the year. While the current resurgence of COVID-19 infections in the US and various regions of the world highlights the ongoing risk that COVID-19 poses for the global economy, we remain cautiously optimistic that the worst impacts of the pandemic for our company are behind us. Furthermore, and as you've heard me say repeatedly in the past, we remain quite pleased with the partnership's durability during challenging economic environment, as demonstrated by its ability to generate free cash flow, continue paying down debt and maintain strong liquidity throughout the past 1.5 years. We believe, this durability will continue. Over the last 12 months, we generated $75 million of free cash flow and paid off $46 million of debt. Our cash flow cushion, which is the free cash flow remaining after paying our private placement debt amortizations and distributions on our common and preferred units was negative by only $13 million. We continue to focus on and maintain robust liquidity and ended the quarter with $98 million of cash and $100 million of unused borrowing capacity. Demand and prices for metallurgical coal are up significantly from the beginning of the year. Resurgence in steel demand, driven by global economic recovery is more than offsetting continued pandemic-related challenges for met coal. The ongoing China-Australia political and trade dispute appears to have been a positive for US producers, as Chinese manufacturers, realign supply chains to procure met coal from other regions, allowing North American coal to make its way to destinations previously served by Australian producers. International benchmark prices for met coal have more than doubled since the beginning of the year, amidst significant volatility, fluctuating within a range of $103 to $215 per ton. NRP has yet to fully realize significant benefits from higher met prices, but we expect that will change in the coming months. As you will recall, most of our lessees' met coal is sold pursuant to contracts of up to a year in duration. So we do not have much sensitivity to short-term price movements. We expect most of those sales contracts to renew in the third and fourth quarters of this year at higher levels, which should provide upside to our met cash flows in the year ahead. Thermal coal demand and prices are also showing significant strength with API two prices recently topping $140 per ton, up over 100% since the beginning of the year. Increased electricity demand driven by a rebound in US economy and a strong winter burn are the primary drivers behind the price run up. The positive impact for us from recent thermal in price increases have been modest, so far since the substantial majority of our thermal cash flows this year are fixed pursuant to our contract with Foresight Energy that went into effect as they emerged from bankruptcy in 2020. That fixed payment agreement terminates at the end of this year, and we will begin to receive traditional royalty payments starting January. As a result, we expect to benefit next year to the extent demand and prices for thermal coal remains strong. Turning to our investment in Ciner Wyoming. Global demand for soda ash has shown significant improvement this year, and is at pre-pandemic levels. International spot prices have risen over 35% since the beginning of the year. Our joint venture in Green River Wyoming is operating at pre-pandemic levels and customer demand for our product is strong. While Ciner Wyoming revenues and profitability have risen significantly over the course of the year, increases in ocean freight rates have been a drag on the bottom line. Looking forward, new lockdowns around the world due to COVID-19, and supply chain constraints on auto production have the potential to weaken demand for soda ash in the coming months. We expect soda ash pricing and logistics costs to remain volatile into 2022, as the market attempts to find a new equilibrium amidst a rapidly changing economic environment. In light of these uncertainties, we do not expect Ciner Wyoming management to resume regular cash distributions to us, until market conditions stabilize. While the near-term outlook is uncertain we are quite optimistic about the intermediate and long-term prospects for our soda ash investment. Our asset is one of the lowest-cost producers of soda ash in the world. And we believe our operating partner Ciner Resources collectively with its parent WE Soda is the best and most capable operator of natural soda ash in the world. These factors position us well to generate attractive margins and robust cash flows over the long term. As mentioned on our last three earnings calls, we continue working to identify alternative revenue sources across our large portfolio of land, mineral and timber assets. The types of opportunities we are exploring include the sequestration of carbon dioxide underground and in standing forests and the generation of electricity using geothermal solar and wind energy. While the timing and likelihood of cash flows being realized from any of these activities is uncertain, we believe our large ownership footprint throughout the United States will provide opportunities to create value in this regard with minimal capital investment by NRP. The partnership's ability to continue generating free cash flow reduce debt and pay unitholder distributions during the COVID-19 downturn demonstrates that we have the right strategy in place to create unitholder value. Since 2015, when we embarked on our strategy of delevering and derisking the partnership, NRP has paid down over $920 million of debt, paid over $125 million of common unitholder distributions and worked to solidify our capital structure, and ensure strong liquidity. We remain steadfast in our commitment to focus on maximizing unitholder value by continuing these efforts. And with that, I'll turn the call over to Chris to cover our financial results. Chris?
