Thank you, Richard. And good morning everyone and thank you for joining us for today's call. To summer highlights for the full year 2020 included, net sales of $350 million, net loss of $98 million, EBITDA of $41 million, which was reduced by $41 million non-cash goodwill impairment and we repurchased over 623,000 CVR Partners, units for $7 million. Looking more specifically at 2020 fourth quarter, we reported net sales of $90 million, a net loss of $17 million and EBITDA of $18 million. We repurchased nearly 394,000 CVR Partners common units for $5 million, and there is no cash available for distribution this quarter. During the fourth quarter 2020, we had strong at both facilities. And Coffeyville, ammonia plant operated at 99% utilization compared to the fourth quarter 2019 at 90%. And East Dubuque, the ammonia plant operated at 103% utilization compared to 88% in the prior year period adjusted for last year's schedule turnaround. Our combined operations produced approximately 220,000 gross tons of ammonia of which 75,000 net tons were available for sale for the fourth quarter 2020. This compares to production of 180,000 gross tons of ammonia of which 55,000 net tons were were available for sale in the prior period. We produced 335,000 tons a UAN in the fourth quarter of 2020 as compared to 286,000 tons in the prior year period, which was impacted by the planned turnaround at East Dubuque. During the fourth quarter of 2020, we sold approximately 325,000 tons of UAN at an average price of $139 a ton, and approximately 114,000 tons of ammonia at an average price of $267 per ton. Year-over-year pricing softened for UAN and ammonia, which were down 21% and 18% respectively. Although prices for nitrogen fertilizers were soft for most of the year, prices began to increase in the fall as crop prices and farmer economics improved. The combination of improving farmer economics and favorable weather drove a strong fall ammonia application season and that strength is carried over into spring demand as well. The outlook for spring plantings and demand for crop inputs remain strong, with the USDA estimating 92 million planted corn acres this year. This is translating into significantly higher prices for UAN and ammonia for the spring, which I will discuss further my closing remarks. I will now turn the call over to Tracy to discuss our financial results.
