Terra Nitrogen Company, L.P. Reports Second Quarter 2014 Results and Announces Cash Distribution

Results for the second quarter of 2014 included an unrealized net mark-to-market loss on natural gas derivatives of $4.9 million compared to a loss of $2.9 million in the second quarter of 2013.

For the first six months of 2014, TNCLP reported net earnings of $203.0 million on net sales of $345.2 million. This compares to net earnings of $316.1 million on net sales of $439.5 million for the first six months of 2013. Net earnings allocable to Common Units was $118.8 million ($6.42 per Common Unit) and $176.2 million ($9.52 per Common Unit) for the first six months of 2014 and 2013, respectively. Results for the first six months of 2014 included an $8.9 million unrealized net mark-to-market loss on natural gas derivatives compared to a gain of $0.8 million for the first six months of 2013.

Net sales for the 2014 second quarter totaled $167.5 million, compared to sales of $215.4million for the 2013 second quarter. This decrease was due to lower average selling prices and sales volume. The decrease in overall prices was due to lower global nitrogen prices driven by increased international supply. Ammonia prices also were lower than in the prior year period due to high industry-wide North American ammonia inventory levels coming into 2014 while UAN prices also decreased due to customers’ reluctance to hold inventory. The decrease in ammonia sales volume was due to the company having lower available inventory to sell due to strong shipments in the first quarter of 2014. UAN sales volume declined due to farmers’ preference for ammonia over UAN.

Net earnings for the 2014 second quarter totaled $100.1 million, compared to net earnings of $149.3 million for the 2013 second quarter. This decrease was due to lower revenue and higher realized natural gas costs.

Cash distributions depend on TNCLP’s earnings as well as cash requirements for working capital needs and capital expenditures. In 2014, TNCLP is expected to have capital expenditures in the range of $70 million to $90 million. A turnaround of approximately 50 percent of the complex is anticipated to occur in the first quarter of 2015 and is expected to have an impact on cash available to fund distributions.
