Thanks, Chuck, and thank you all for joining us. Yesterday afternoon, we reported first quarter results that were strong in their own right and I believe point to an excellent spring season for CF Industries. Net earnings totaled $158.8 million or $2.77 per diluted common share, up sharply from the $57.2 million or $2.02 per share that we earned in last year's first quarter. This represents exceptionally strong performance for our first quarter, particularly one that was as wet as it was this year. Driving that improvement was a strong pricing environment for all of our products, an environment that signals robust demand for crops and for the fertilizers required to maximize the yield and health of those crops. For the quarter that strong pricing produced net sales of $667.3 million, a 41% increase over last year. I am pleased with our first quarter performance. But keep in mind that especially in nitrogen, the first quarter is a bit like spring training in baseball. You do put numbers on the board, and its greater for good ones, it certainly were for CF industries. However, the regular season doesn't normally begin until the second quarter, that's when the first quarter's hard work really begins to count. But having said that, during our first quarter we achieved high and cost effective operating rates at our manufacturing operations. Even with the reported outage at the Medicine Hat Nitrogen Complex, we recorded a 96% capacity utilization in nitrogen. Meeting sales commitments and positioning more than a million tons of ammonia, urea, and UAN solution in our in-market terminals and warehouses, ready to serve customers. In phosphate, we achieved a strong 94% operating rate. One key to maintaining that rate was our success in obtaining inadequate supply of sulfur. In what was and remains a challenge in sulfur supply environment, I believe we benefited from long standing relationships with our major suppliers. During the quarter, we had no sulfur related production shortfalls for DAP and MAP. In fact, we actually produced 27,000 more tons of those products than we did in last year's first quarter. During the quarter then, we achieved significantly improved financial performance and thanks to the product positioned in our distribution network, set to stage to meet customers needs, in what is expected to be a robust spring planting season. Now, Tony Nocchiero, our Chief Financial Officer will provide some added detail on our financial performance.
