Results for the fourth quarter of 2012 included an unrealized mark-to-market gain on natural gas derivatives of $1.0 million compared to a loss of $7.5 million in the fourth quarter of 2011. The increase in sales was due to higher ammonia and urea ammonium nitrate solution (UAN) product volumes and higher average ammonia selling prices.

For the year, the company reported total net sales $780.1 million against $798.9 million for the same period a year ago. Earnings from operations were $560.8 million against $507.9 million for the same period a year ago. Net earnings were $560.8 million against $508.0 million for the same period a year ago.

Net earnings allocation to class B common units was $5.5 million against $5.0 million a year ago. Net earnings per common unit were $17.06 against $15.33 a year ago. The decrease in sales was due to lower ammonia and UAN volumes and a lower UAN average selling price. The volume decline was due primarily to the timing impact of the implementation of a new Services and Offtake Agreement with CF Industries on January 1, 2011, which resulted in a one-time increase in sales volume recognized upon adoption of the agreement. Capital expenditures were $46.7 million as compared to $8.7 million in 2011.

For the year 2013, the company is expected to have capital expenditures in the range of $75 million to $100 million. The capital program includes a rail yard expansion, new ammonia and UAN storage tanks, and control and electrical system upgrades.
