Terra Nitrogen Company, L.P. Reports Third Quarter 2012 Results and Announces Cash Distribution

DEERFIELD, IL (November 5, 2012)—Terra Nitrogen Company, L.P. (TNCLP) (NYSE: TNH) today reported net earnings of $131.8 million on net sales of $181.1 million for the third quarter ended September 30, 2012.  This compares to net earnings of $128.4 million on net sales of $203.3 million for the 2011 third quarter.  Net income allocable to common units was $73.9 million ($4.00 per common unit) and $72.4 million ($3.91 per common unit) for the 2012 and 2011 third quarters, respectively.  Results for the third quarter of 2012 included an unrealized non-cash mark-to-market gain on natural gas derivatives of $7.1 million compared to a loss of $1.8 million in the third quarter of 2011.

For the first nine months of 2012, TNCLP reported net earnings of $410.8 million on net sales of $573.6 million.  This compares to net earnings of $378.2 million on net sales of $597.9 million for the first nine months of 2011.  Net earnings allocable to common units was $230.3 million ($12.45 per common unit) and $212.1 million ($11.46 per common unit) for the first nine months of 2012 and 2011, respectively.  Results for the first nine months of 2012 included a $9.6 million unrealized non-cash mark-to-market gain on natural gas derivatives compared to a loss of $4.4 million for the first nine months of 2011.

Analysis of Results
Net sales for the 2012 third quarter totaled $181.1 million, compared to sales of $203.3 million for the 2011 third quarter.  This decrease was due to lower ammonia and UAN sales volume and lower UAN average selling prices, which were offset partially by higher ammonia average selling prices.  Ammonia and UAN sales volume declined as drought conditions impacted fertilizer application rates and UAN volume was also impacted by higher imports during the third quarter of 2012 as compared to the third quarter of 2011.  The decrease in UAN selling prices was due to increased industry-wide supply in the marketplace compared to the same period last year.  The increase in ammonia selling prices for the third quarter of 2012 as compared to 2011 was due to tight North American producer inventory and lower ammonia supply globally.

Comparing the 2012 to the 2011 third quarter, TNCLP’s:

·                  Ammonia average selling prices were up 14% but sales volume was down 8%;

·                  UAN average selling prices were down 8% and sales volume was down 5%; and

·                  Realized natural gas costs per mmBtu decreased by 27 percent.

Cash Distribution
TNCLP today reported the declaration of a cash distribution for the quarter ended September 30, 2012, of $4.12 per common limited partnership unit payable November 29, 2012, to holders of record as of November 16, 2012.

This release serves as a qualified notice to nominees and brokers as provided for under Treasury Regulation Section 1.1446-4(b). Please note that 100 percent of the Partnership’s distributions to foreign investors are attributable to income that effectively is connected with a United States trade or business. Accordingly, the Partnership’s distributions to foreign investors are subject to federal income tax withholding at the highest effective tax rate.

Cash distributions depend on TNCLP’s earnings, which can be affected by nitrogen fertilizer selling prices, natural gas costs, seasonal demand factors, production levels and weather, as well as cash requirements for working capital needs and capital expenditures. Cash distributions per limited partnership unit also vary based on increasing amounts allocable to the General Partner when cumulative distributions exceed targeted levels. With this distribution, TNCLP cumulative distributions continue to exceed targeted levels.
