  Results

Business Wire

DEERFIELD, Ill. -- February 19, 2013

Terra Nitrogen Company, L.P. (TNCLP) (NYSE: TNH) today reported net earnings
of $150.0 million on sales of $206.5 million for the quarter ended December
31, 2012. This compares to net earnings of $129.8 million on sales of $201.0
million for the 2011 fourth quarter. Net income allocable to Common Units was
$85.3 million ($4.61 per Common Unit) and $71.5 million ($3.87 per Common
Unit) for the 2012 and 2011 fourth quarters, respectively.

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.

For the full year 2012, TNCLP reported net earnings of $560.8 million on sales
of $780.1 million. This compares to net earnings of $508.0 million on sales of
$798.9 million in 2011. Net income allocable to Common Units was $315.6
million ($17.06 per Common Unit) and $283.6 million ($15.33 per Common Unit)
in 2012 and 2011, respectively. The company had very strong operating results
during 2012 and set a new ammonia production record.

Analysis of Results

Sales for the 2012 fourth quarter totaled $206.5 million, compared to sales of
$201.0 million for the 2011 fourth quarter. This increase was due to higher
ammonia and urea ammonium nitrate solution (UAN) product volumes and higher
average ammonia selling prices.

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

  * Ammonia average selling prices increased by 28 percent and UAN average
    selling prices decreased by 16 percent;
  * Ammonia and UAN sales volumes increased by 17 and 5 percent, respectively;
    and
  * Realized natural gas cost per MMBtu decreased by 16 percent.

Sales for the full year totaled $780.1 million, compared to sales of $798.9
million in 2011. This decrease 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.

Comparing the full year 2012 to 2011, TNCLP’s:

  * Ammonia average selling price increased by 16 percent and UAN average
    selling price decreased by 4 percent;
  * Ammonia and UAN sales volumes decreased by 4 and 2 percent, respectively;
    and
  * Realized natural gas cost per MMBtu decreased by 23 percent.

Cash Distribution

TNCLP reported on February 8, 2013 the declaration of a cash distribution for
the quarter ended December 31, 2012, of $3.63 per common limited partnership
unit payable February 28, 2013, to holders of record as of February 19, 2013.

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. In 2012, capital expenditures
were $46.7 million as compared to $8.7 million in 2011. In 2013, TNCLP 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. Some of these
projects may extend beyond 2013. 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.

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 is effectively 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.
