TERRA NITROGEN COMPANY, L.P.

Notes to Unaudited Consolidated Financial Statements
1. Background and Basis of Presentation
Terra Nitrogen Company, L.P. ("TNCLP," "we," "our" or "us") is a Delaware limited partnership that produces nitrogen fertilizer products. Our principal products are anhydrous ammonia (ammonia) and urea ammonium nitrate solution (UAN), which we manufacture at our facility in Verdigris, Oklahoma.
We conduct our operations through an operating partnership, Terra Nitrogen, Limited Partnership (TNLP or the Operating Partnership, and collectively with TNCLP, the Partnership). Terra Nitrogen GP Inc. (TNGP or the General Partner), a Delaware corporation, is the general partner of both TNCLP and TNLP and owns a consolidated 0.05% general partner interest in the Partnership. The General Partner is an indirect, wholly owned subsidiary of CF Industries Holdings, Inc. (CF Industries), a Delaware corporation. Ownership of TNCLP is comprised of the general partner interests and the limited partner interests. Limited partner interests are represented by common units, which are listed for trading on the New York Stock Exchange under the symbol "TNH" and Class B common units. As of September 30, 2016, we had 18,501,576 common units and 184,072 Class B common units issued and outstanding. CF Industries through its subsidiaries owned 13,889,014 common units (representing approximately 75% of the total outstanding common units) and all of the Class B common units as of September 30, 2016.
We are a master limited partnership (MLP). Partnerships are generally not subject to federal income tax, although publicly traded partnerships (such as TNCLP) are treated as corporations for federal income tax purposes (and therefore are subject to federal income tax), unless at least 90% of the partnership's gross income is "qualifying income" as defined in Section 7704 of the Internal Revenue Code of 1986, as amended, and the partnership is not required to register as an investment company under the Investment Company Act of 1940. As we currently satisfy the requirements to be treated as a partnership for federal income tax purposes, no federal income taxes are paid by the Partnership.
On May 6, 2015, the Internal Revenue Service (IRS) published proposed regulations on the types of income and activities that constitute or generate qualifying income of an MLP. The proposed regulations would have the effect of limiting the types of income and activities that qualify under the MLP rules, subject to certain transition provisions. The proposed regulations include certain processing or refining and transportation activities with respect to any mineral or natural resource (including fertilizer) as activities that generate qualifying income, but the proposed regulations reserve on specific proposals regarding fertilizer-related activities. Any change in the federal income tax treatment of income from fertilizer-related activities as qualifying income could have a material impact on the taxation of the Partnership and could have a material adverse impact on unitholder distributions. We continue to monitor these IRS regulatory activities.
The accompanying unaudited interim consolidated financial statements have been prepared on the same basis as our audited consolidated financial statements for the year ended December 31, 2015, in accordance with accounting principles generally accepted in the United States for interim financial reporting. In the opinion of management, these statements reflect all adjustments, consisting only of normal and recurring adjustments, that are necessary for the fair representation of the information for the periods presented. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. Operating results for any period presented apply to that period only and are not necessarily indicative of results for any future period.
The preparation of the unaudited interim consolidated financial statements requires management to make use of estimates and assumptions that affect the reported amount of assets and liabilities, revenue and expenses and certain financial statement disclosures. Actual results could differ from these estimates. Significant estimates and assumptions in these unaudited interim consolidated financial statements include net realizable value of inventories, environmental remediation liabilities, environmental and litigation contingencies, useful lives of property, plant and equipment, and the assumptions used in the evaluation of potential impairment of property, plant and equipment.
The accompanying unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and related disclosures included in our 2015 Annual Report on Form 10-K filed with the SEC on February 25, 2016.
Throughout this document, the term "affiliates of the General Partner" refers to consolidated subsidiaries of CF Industries, including TNGP.

2. New Accounting Standards
In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in Accounting Standards Codification (ASC) Topic 840, Leases. This ASU will require lessees to recognize the rights and obligations resulting from virtually all leases (other than leases that meet the definition of a short-term lease) on their balance sheets as right-of-use assets with corresponding lease liabilities. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of income and expense recognized and expected to be recognized from existing contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and requires the modified retrospective method of adoption. We expect the adoption of this ASU will not have a material impact on our consolidated financial statements.
In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, effective for annual and interim periods beginning after December 15, 2016. ASU No. 2015-11 changes the inventory measurement principle for entities using the first-in, first out (FIFO) or average cost methods. For entities utilizing one of these methods, the inventory measurement principle will change from lower of cost or market to the lower of cost and net realizable value. We follow the FIFO or average cost methods and are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments. Additionally, the costs to obtain and fulfill a contract, including assets to be recognized, are to be capitalized and such capitalized costs should be disclosed. As modified by ASU No. 2015-14, Deferral of the Effective Date, the effective date of ASU No. 2014-09 is for interim and annual periods beginning after December 15, 2017, with early adoption permitted for interim and annual periods beginning after December 15, 2016. We are currently evaluating the impact of the adoption of ASU No. 2014-09, as amended, on our consolidated financial statements.
3. Agreement of Limited Partnership
We make quarterly distributions to holders of our general partner interest and limited partner interests based on Available Cash for the quarter as defined in our agreement of limited partnership. Available Cash is defined generally as all cash receipts less all cash disbursements, less certain reserves (including reserves for future operating and capital needs) established as the General Partner determines in its reasonable discretion to be necessary or appropriate. Changes in working capital affect Available Cash as changes in the amount of cash invested in working capital items (such as increases in inventory and decreases in accounts payable) reduce Available Cash, while declines in the amount of cash invested in working capital items increase Available Cash. During the nine months ended September 30, 2016 and 2015, we declared and paid partnership distributions of $208.5 million and $207.3 million, respectively.
We receive 99% of the Available Cash from the Operating Partnership and 1% is distributed by the Operating Partnership to the General Partner. Cash distributions from the Operating Partnership generally represent the Operating Partnership's Available Cash from operations. Our cash distributions are made 99.975% to common and Class B common unitholders and 0.025% to the General Partner except when cumulative distributions of Available Cash exceed specified target levels above the Minimum Quarterly Distributions (MQD) of $0.605 per unit. Under such circumstances, the General Partner is entitled to receive Incentive Distribution Rights.

TERRA NITROGEN COMPANY, L.P.

On November 2, 2016, we announced a $1.77 cash distribution per common unit, payable on November 30, 2016 to holders of record as of November 15, 2016. In the third quarter of 2016, we exceeded the cumulative MQD amounts and will distribute Available Cash as summarized in the following table:

As of September 30, 2016, the General Partner and its affiliates owned 75.3% of our outstanding units. When not more than 25% of our issued and outstanding units are held by non-affiliates of the General Partner, as was the case at September 30, 2016, we, at the General Partner's sole discretion, may call, or assign to the General Partner or its affiliates, our right to acquire all, but not less than all, such outstanding units held by non-affiliated persons. If the General Partner elects to acquire all outstanding units, we are required to give at least 30 but not more than 60 days' notice of our decision to purchase the outstanding units. The purchase price per unit will be the greater of (1) the average of the previous 20 trading days' closing prices as of the date five days before the purchase is announced or (2) the highest price paid by the General Partner or any of its affiliates for any unit within the 90 days preceding the date the purchase is announced.

6. Derivative Financial Instruments
Derivative financial instruments are executed on our behalf by an affiliate of the General Partner to reduce our exposure to changes in commodity prices for natural gas. Natural gas is the largest and most volatile component of the manufacturing cost for nitrogen-based fertilizers.
The derivatives that we use are primarily natural gas fixed price swaps and natural gas options traded in the over-the-counter (OTC) markets. The derivative contract prices are based on NYMEX future prices based on physical delivery of natural gas at the Henry Hub in Louisiana, the most common and financially liquid location of reference for derivative financial instruments related to natural gas. However, we purchase natural gas for our manufacturing facility from suppliers whose prices are based primarily on the ONEOK index (based on physical delivery of natural gas in Oklahoma, rather than at the Henry Hub). This creates a location basis differential between the derivative contract price and the price we pay for physical delivery of natural gas. Accordingly, the prices underlying the derivative financial instruments we use may not exactly match the prices of natural gas we purchase and consume. We enter into natural gas derivative contracts with respect to gas to be consumed by us in the future, and settlement of those derivative contracts are scheduled to coincide with our anticipated purchases of natural gas used to manufacture nitrogen products during those future periods. We use natural gas derivatives as an economic hedge of gas price risk, but without the application of hedge accounting.
We report derivatives on our consolidated balance sheets at fair value. Changes in fair value are recognized in cost of goods sold in the period of change. Cash flows related to natural gas derivatives are reported as operating activities.
The gross fair values of derivatives on our consolidated balance sheets are shown below.

As of September 30, 2016 and December 31, 2015, we had open derivative contracts for 36.9 million MMBtus (millions of British thermal units) and 59.6 million MMBtus, respectively, of natural gas. The derivative portfolio at September 30, 2016 includes natural gas derivatives that hedge a portion of anticipated natural gas purchases through December 2018. For the nine months ended September 30, 2016, we used derivatives to cover approximately 77% of our natural gas consumption.

TERRA NITROGEN COMPANY, L.P.

As of September 30, 2016 and December 31, 2015, the aggregate fair values of the derivative instruments with credit-risk-related contingent features in a net liability position were $6.2 million and $27.9 million, respectively, which also approximates the fair value of the maximum amount of additional collateral that would need to be posted or assets needed to settle the obligations if the credit-risk-related contingent features were triggered at the reporting dates. As of September 30, 2016 and December 31, 2015, we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with International Swaps and Derivatives Association (ISDA) agreements generally provide the right to set off collateral against amounts owing under the ISDA agreements upon the occurrence of a default or a specified termination event.

Cash and Cash Equivalents
As of September 30, 2016 and December 31, 2015, our cash and cash equivalents consisted primarily of money market mutual funds that invest in U.S. treasuries and government obligations or direct investments in U.S. and Canadian treasury bills.
Natural Gas Derivatives
The derivative instruments that we use are primarily natural gas fixed price swaps and options traded in the OTC markets with multi-national commercial banks, other major financial institutions and large energy companies. The derivatives are traded in months forward and settlements are scheduled to coincide with anticipated gas purchases during those future periods. These contracts settle using NYMEX futures prices and accordingly, to determine the fair value of these instruments, we use quoted market prices from NYMEX and standard pricing models with inputs derived from or corroborated by observable market data such as forward curves supplied by an industry-recognized unrelated third party. See Note 6—Derivative Financial Instruments for additional information.
Assets Measured at Fair Value on a Nonrecurring Basis
We also have assets that may be measured at fair value on a nonrecurring basis; that is, the assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. These include long-lived assets that may be written down to fair value as a result of impairment. We determined that these fair value measurements rely primarily on Partnership-specific inputs and the Partnership's assumptions about the use of the assets. Since certain of the assumptions would involve inputs that are not observable, these fair values would reside within Level 3 of the fair value hierarchy.

Scheduled replacements and overhauls of machinery and equipment include the dismantling, repair or replacement and installation of various components including piping, valves, motors, turbines, pumps, compressors, heat exchangers and the replacement of catalyst when a full plant shutdown occurs. Scheduled inspections are also conducted during full plant shutdowns, including required safety inspections which entail the disassembly of various components such as steam boilers, pressure vessels and other equipment requiring safety certifications. Internal employee costs and overhead are not considered turnaround costs and are not capitalized.
9. Related Party Transactions
TNCLP and TNGP have no employees. We have entered into several agreements with a subsidiary of CF Industries relating to the operation of our business and the sale of the fertilizer products produced at our Verdigris facility. We believe that each of these agreements is on terms that are fair and reasonable to us.
General and Administrative Services and Product Offtake Agreement
Pursuant to the Amendment to the General and Administrative Services and Product Offtake Agreement (the Services and Offtake Agreement), the Partnership sells all of its fertilizer products to affiliates of the General Partner at prices based on market prices for the Partnership's fertilizer products as defined in the Services and Offtake Agreement. Title and risk of loss transfer to affiliates of the General Partner as the product is shipped from the plant gate. The Services and Offtake Agreement is effective for annual terms starting as of January 1st and will be extended automatically for successive one-year terms unless terminated by one of the parties prior to renewal.

12

TERRA NITROGEN COMPANY, L.P.

Directly Incurred Charges
Since we have no employees, we rely on employees from an affiliate of the General Partner to operate our Verdigris facility. As a result, the payroll and payroll-related expenses and benefit costs, such as health insurance and pension costs, are incurred by an affiliate of the General Partner and directly charged to us. Payroll, payroll-related expenses and other employee-related benefit costs directly charged to us for the three and nine months ended September 30, 2016 were $7.2 million and $21.3 million, respectively, and for the three and nine months ended September 30, 2015 were $6.6 million and $20.7 million, respectively. We report these expenses as services provided by affiliates of the General Partner in cost of goods sold.
Allocated Charges
CF Industries, together with its affiliates, also provides certain services to us under the Services and Offtake Agreement. These services include production planning, manufacturing management, logistics, procurement, accounting, legal, risk management, investor relations and other general and administrative functions. Allocated expenses charged to us for the three and nine months ended September 30, 2016 were $4.0 million and $11.8 million, respectively, and for the three and nine months ended September 30, 2015 were $3.9 million and $11.8 million, respectively. We report these expenses as selling, general and administrative services provided by affiliates of the General Partner.
Amounts Due to/from Affiliates of the General Partner
We receive cash and make expenditures directly from our cash accounts. Because we sell our products to and receive payroll and other related services from affiliates of the General Partner, the affiliates of the General Partner continue to be both debtors and creditors to us. As of September 30, 2016 and December 31, 2015, we had a net balance due from affiliates of the General Partner of $4.3 million and $5.9 million, respectively.
Spare Parts Sharing Agreement
Affiliates of CF Industries own and operate nitrogen fertilizer complexes that utilize some equipment that is similar to equipment at our Verdigris nitrogen complex. Each of the various manufacturing complexes maintains spare parts for use in its facilities. In the event that an unplanned need arises and to help minimize manufacturing downtime, we have entered into a spare parts sharing agreement with affiliates of CF Industries that permits spare parts to be shared among the manufacturing complexes from time to time. Parts that are borrowed from another complex under the agreement are either refurbished and returned to the lender or replaced.
Leases
We entered into an amended and restated lease with an affiliate of the General Partner under which the ammonia assets in our terminal in Blair, Nebraska are leased by the affiliate. The lease is effective for a five-year term ending on December 31, 2018, and the affiliate of the General Partner has options to renew for three additional five-year terms. The quarterly lease payment is $100,000, subject to an annual inflation adjustment, and additional rent will be paid equal to all costs, expenses, and obligations incurred by the affiliate of the General Partner related to the use, occupancy and operation of the terminal.
We also have leased certain of our rail cars to an affiliate of the General Partner for quarterly rental payments of $3,600 per car. This lease was effective initially for a one-year term and is extended automatically for successive one-year terms unless terminated by either party thereto prior to renewal.
For both the three and nine months ended September 30, 2016 and 2015, we recognized rental income of $0.1 million and $0.4 million, respectively. We report this income as other income from an affiliate of the General Partner.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
You should read the following discussion and analysis in conjunction with Terra Nitrogen Company, L.P.'s ("TNCLP," "we," "our" or "us") annual consolidated financial statements and related notes, which are included in our 2015 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 25, 2016 (2015 Annual Report), as well as our Unaudited Consolidated Financial Statements and the related Notes thereto contained in Part I, Item 1 of this report.
We conduct our operations through an operating partnership, Terra Nitrogen, Limited Partnership (TNLP or the Operating Partnership, and collectively with TNCLP, the Partnership). Terra Nitrogen GP Inc. (TNGP or the General Partner), a Delaware corporation, is the General Partner of both TNCLP and TNLP and owns a consolidated 0.05% general partner interest in the Partnership. The General Partner is an indirect, wholly owned subsidiary of CF Industries Holdings, Inc. (CF Industries), a Delaware corporation.
CF Industries, through its subsidiaries, is a global leader in the manufacturing and distribution of nitrogen fertilizer and other nitrogen products, serving both agricultural and industrial customers. CF Industries operates world-class nitrogen fertilizer manufacturing complexes in the United States, Canada and the United Kingdom and distributes nitrogen fertilizer products through a system of terminals, warehouses, and associated transportation equipment located primarily in the midwestern United States.
Throughout this document, references to "affiliates of the General Partner" refer to consolidated subsidiaries of CF Industries, including TNGP.
Dependence on CF Industries
We are dependent on CF Industries for our success in a number of respects. Affiliates of CF Industries are obligated to take all of the production from our Verdigris manufacturing complex. Affiliates of CF Industries provide certain services to us, including production planning, manufacturing management, logistics, procurement, accounting, legal, risk management, investor relations and other general and administrative services. For additional information concerning CF Industries, refer to CF Industries' filings with the SEC on Form 10-K, Form 10-Q and current reports on Form 8-K, and for further information regarding transactions with CF Industries, please refer to Notes to Unaudited Consolidated Financial Statements, Note 9—Related Party Transactions.
Company Overview
TNCLP is a Delaware limited partnership that produces nitrogen fertilizer products. Our principal products are anhydrous ammonia (ammonia) and urea ammonium nitrate solution (UAN), which we manufacture at our facility in Verdigris, Oklahoma.
TNCLP and TNGP have no employees. An affiliate of the General Partner provides certain services to us under the Amendment to the General and Administrative Services and Product Offtake Agreement (the Services and Offtake Agreement). Pursuant to the Services and Offtake Agreement, the Partnership sells all of its fertilizer products to affiliates of the General Partner at prices based on market prices for the Partnership's fertilizer products as defined in the Services and Offtake Agreement. Title and risk of loss transfer to affiliates of the General Partner as the product is shipped from the plant gate. For further information regarding our agreements with CF Industries and the General Partner, see Notes to Unaudited Consolidated Financial Statements, Note 9—Related Party Transactions.
Nitrogen Fertilizer Market Conditions
Our products are global commodities and are subject to price competition. The customers for our products make their purchasing decisions principally on the basis of delivered price and, to a lesser extent, on customer service and product quality. The selling prices of our products fluctuate in response to global market conditions and changes in supply and demand. In the current environment, global nitrogen fertilizer supply has increased faster than global nitrogen fertilizer demand, creating the current global oversupply of nitrogen fertilizer and leading to lower selling prices.
The third quarter and first nine months of 2016 were significantly impacted by declining selling prices. Our average selling prices for ammonia and UAN declined by 35% and 33%, respectively, during the third quarter of 2016 as compared to the third quarter of 2015, which reduced both our net sales and gross margin in the third quarter of 2016 by $45.2 million. During the first nine months of 2016, our average selling prices for ammonia and UAN declined by 29% and 24%, respectively, which reduced both our net sales and gross margin in the first nine months of 2016 by $114.9 million

14

TERRA NITROGEN COMPANY, L.P.

Over the past several years, strong demand, high capacity utilization and increasing operating margins as a result of higher global nitrogen fertilizer prices stimulated global investment in nitrogen production facilities, which resulted in an increase in global nitrogen fertilizer production capacity and the current surplus of supply in the market. Global investment in nitrogen production facilities includes the capacity expansion projects that are being completed by affiliates of our General Partner. In addition, lower global production costs, driven by lower feedstock costs and foreign exchange rate changes, and reduced ocean freight costs have further contributed to the lower priced environment.
We expect the lower priced environment to continue until global supply and demand become more balanced through a combination of continued demand growth and supply reductions as producers respond to lower realized margins by taking higher cost production facilities off line.
Results of Operations
We reported net earnings of $28.8 million for the three months ended September 30, 2016 on net sales of $90.2 million, compared with net earnings of $69.4 million for the three months ended September 30, 2015 on net sales of $150.2 million.

Third Quarter of 2016 Compared to the Third Quarter of 2015
Our net sales for the third quarter of 2016 were $90.2 million, a decrease of $60.0 million, or 40%, from the third quarter of 2015 net sales of $150.2 million. The decrease was primarily due to lower average selling prices for both UAN and ammonia in the third quarter of 2016 versus the third quarter of 2015 and lower UAN sales volume, partially offset by higher ammonia sales volume.
UAN selling prices declined by 33% from $211 per ton in the third quarter of 2015 to $142 per ton in the third quarter of 2016 due to the global fertilizer industry oversupply for all nitrogen fertilizer products. UAN sales volume decreased by 24% in the third quarter of 2016 to 415,000 tons from 544,000 tons in the third quarter of 2015 as customers for our products delayed purchases in anticipation of lower prices due to the global oversupply conditions.
Ammonia average selling prices declined by 35% from $459 per ton in the third quarter of 2015 to $297 per ton in the third quarter of 2016 due to the global fertilizer industry oversupply for all nitrogen fertilizer products. Ammonia sales volume increased by 37% from 75,000 tons in the third quarter of 2015 to 103,000 tons in the third quarter of 2016, due to more favorable demand conditions for ammonia versus UAN in the current oversupply environment and lower production of UAN.

The average cost of goods sold decreased to $111 per ton in the third quarter of 2016 from $123 per ton in the third quarter of 2015. The 10% decrease in the average cost of goods sold per ton was due primarily to lower unrealized mark-to-market losses on natural gas derivatives. We recorded a $3.3 million unrealized net mark-to-market loss on natural gas derivatives for the third quarter of 2016, compared to a $17.0 million unrealized net mark-to-market loss for the third quarter of 2015. The derivative portfolio at September 30, 2016 includes natural gas derivatives that hedge a portion of anticipated natural gas purchases through December 2018.
Our gross margin was $32.8 million in the third quarter of 2016 compared to $74.1 million in the third quarter of 2015. Gross margin as a percentage of net sales decreased to 36.4% during the third quarter of 2016 from 49.3% during the third quarter of 2015 as a result of the impact of lower average selling prices for both UAN and ammonia and lower UAN sales volume in the third quarter of 2016 compared to the third quarter 2015, partially offset by lower unrealized net mark-to-market losses on natural gas derivatives during the third quarter of 2016 and higher ammonia sales volume.
Total selling, general and administrative expenses, including other general and administrative expenses, were $4.0 million in the third quarter of 2016 compared to $4.7 million in the third quarter of 2015. The decline was due primarily to a loss in the third quarter of 2015 on the disposal of certain machinery and equipment.
Our net earnings were $28.8 million in the third quarter of 2016, a decrease of $40.6 million, or 59%, as compared to $69.4 million in the third quarter of 2015. Net earnings decreased primarily due to the lower gross margin driven by lower average selling prices, as discussed above.

Nine Months Ended September 30, 2016 Compared to Nine Months Ended September 30, 2015
In the first quarter of 2016, we experienced an unscheduled outage for maintenance on one of the facility’s two ammonia plants, resulting in one-half of the complex's ammonia capacity being shut down for approximately two months, and one-half of the complex's UAN capacity being shut down for approximately one month. Maintenance was completed and the affected ammonia plant was restarted in March 2016. In the first quarter of 2015, we had a planned turnaround of an ammonia plant and a UAN plant, together representing approximately one-half of our production capacity. The ammonia plant turnaround was completed in the first quarter of 2015 and the UAN plant turnaround, including certain follow-on maintenance, was completed in the second quarter of 2015. These turnarounds reduced production in the nine months ended September 30, 2015.
Our net sales for the nine months ended September 30, 2016 were $324.9 million, a decrease of $105.5 million, or 25%, from net sales of $430.4 million for the nine months ended September 30, 2015. This decrease was due primarily to a decrease in UAN and ammonia average selling prices as a result of the global fertilizer industry oversupply for all nitrogen fertilizer products. This was partially offset by higher UAN and ammonia sales volume compared to the nine months ended September 30, 2015.
UAN selling prices declined by 24% from $234 per ton in the nine months ended September 30, 2015 to $177 per ton in the nine months ended September 30, 2016 due to the global fertilizer industry oversupply for all nitrogen fertilizer products. UAN sales volume increased by 2% in the nine months ended September 30, 2016 to 1,231,000 tons from 1,207,000 tons in the nine months ended September 30, 2015 due to increased UAN production.
Ammonia selling prices decreased by 29% from $492 per ton in the nine months ended September 30, 2015 to $347 per ton in the nine months ended September 30, 2016. The decrease in ammonia selling prices was due to the global fertilizer industry oversupply for all nitrogen fertilizer products. Ammonia sales volume increased from 296,000 tons in the nine months ended September 30, 2015 to 306,000 tons in the nine months ended September 30, 2016, due to increased production.

N/M - Not Meaningful
The average cost of goods sold per ton decreased to $95 per ton in the nine months ended September 30, 2016 from $125 per ton in the nine months ended September 30, 2015. The 24% decrease in the average cost of goods sold per ton was due primarily to an unrealized mark-to-market gain of $21.7 million in the first nine months of 2016 compared to an unrealized mark-to-market loss of $10.5 million in the same period in 2015, as well as lower idle plant costs due to the turnarounds that occurred in the first half of 2015.
Our gross margin was $178.6 million in the nine months ended September 30, 2016 compared to $242.8 million in the nine months ended September 30, 2015. The gross margin in the nine months ended September 30, 2016 declined 26% from the nine months ended September 30, 2015 primarily due to lower UAN and ammonia average selling prices partially offset by an unrealized net mark-to-market gain in natural gas derivatives and higher sales volume in the first nine months of 2016 compared to the first nine months of 2015. Gross margin as a percentage of net sales decreased to 55.0% during the nine months ended September 30, 2016 from 56.4% during the nine months ended September 30, 2015.
Total selling, general and administrative expenses, including other general and administrative expenses, were $13.5 million in the nine months ended September 30, 2016 compared to $15.1 million in the nine months ended September 30, 2015. The decline was due primarily to a loss in the first nine months of 2015 on the disposal of certain machinery and equipment.

TERRA NITROGEN COMPANY, L.P.

Our net earnings were $165.2 million in the nine months ended September 30, 2016, a decrease of $62.5 million, or 27%, as compared to $227.7 million in the nine months ended September 30, 2015. Net earnings decreased primarily due to the lower gross margin driven by lower average selling prices, as discussed above.
Liquidity and Capital Resources
Our principal funding needs and uses of cash are working capital, plant turnaround costs, capital expenditures, and quarterly distributions. Our cash and cash equivalents balance as of September 30, 2016 was $48.7 million, a decrease of $57.7 million from $106.4 million as of December 31, 2015. See further discussion below under "Cash Flows." Our cash and cash equivalents consist primarily of money market mutual funds that invest in U.S. treasuries and government obligations or direct investments in U.S. and Canadian treasury bills.
Because we sell our products to, and receive payroll and other related services from, affiliates of the General Partner, the affiliates of the General Partner continue to be both debtors and creditors to us.
Cash Flows

Operating Activities
Net cash provided by operating activities was $175.6 million in the first nine months of 2016 compared to $267.8 million in the same period of 2015, or a decline of $92.2 million. This decrease was due primarily to the $62.5 million decrease in net earnings. Net earnings included depreciation and amortization expense of $29.9 million and $25.5 million during the nine months ended September 30, 2016 and 2015, respectively, and unrealized net mark-to-market (gain) loss of $(21.7) million and $11.6 million during the nine months ended September 30, 2016, and 2015, respectively, on natural gas derivatives.
Investing Activities
Net cash used in investing activities was $24.8 million in the first nine months of 2016 compared to $81.0 million in the first nine months of 2015. The $56.2 million decrease in cash used in investing activities in 2016 was due to higher capital expenditures in the first nine months of 2015 due to planned plant turnaround activities.
Financing Activities
Net cash used in financing activities was $208.5 million in the first nine months of 2016 compared to $207.3 million in the first nine months of 2015, and consists of distributions paid to our unitholders. The distributions paid are based on "Available Cash," as defined in our agreement of limited partnership. See further discussion below under "Partnership Distributions."
Capital Expenditures
Capital expenditures totaled $24.8 million during the nine months ended September 30, 2016 compared to $81.9 million during the nine months ended September 30, 2015, with the decrease primarily resulting from the cost of turnarounds in the first half of 2015. We expect total 2016 capital expenditures will be in the range of $35 million to $40 million. Capital expenditures are made to sustain our asset base, to increase capacity, to improve plant efficiency and to comply with various environmental, health and safety requirements. Due to the size, scope and timing of capital projects, certain projects require more than a year to complete. Planned capital expenditures and turnarounds are subject to change due to delays in regulatory approvals and/or permitting, unanticipated increases in cost, changes in scope and completion time, performance of third parties, adverse weather, defects in materials and workmanship, labor or material shortages, transportation constraints, and other unforeseen difficulties. Capital expenditures reduce the Available Cash for unitholder distributions.

General Partner
The General Partner is an indirect, wholly owned subsidiary of CF Industries. Under the General Partner's governing documents, neither we nor the General Partner may make any bankruptcy filing (or take similar action) without the approval of the General Partner's independent directors, except in specified circumstances if there are not two independent directors on the General Partner's board of directors.
Partnership Distributions
We make quarterly distributions to holders of our general partner interest and limited partner interests based on Available Cash for the quarter as defined in our agreement of limited partnership. Available Cash is defined generally as all cash receipts less all cash disbursements, less certain reserves (including reserves for future operating and capital needs) established as the General Partner determines in its reasonable discretion to be necessary or appropriate. Changes in working capital affect Available Cash, as changes in the amount of cash invested in working capital items (such as increases in inventory and decreases in accounts payable) reduce Available Cash, while declines in the amount of cash invested in working capital items increase Available Cash. During the nine months ended September 30, 2016 and 2015, we declared and paid partnership distributions of $208.5 million and $207.3 million, respectively.
We receive 99% of the Available Cash from the Operating Partnership and 1% is distributed by the Operating Partnership to the General Partner. Cash distributions from the Operating Partnership generally represent the Operating Partnership's Available Cash from operations. Our cash distributions are made 99.975% to common and Class B common unitholders and 0.025% to the General Partner except when cumulative distributions of Available Cash exceed specified target levels above the Minimum Quarterly Distributions (MQD) of $0.605 per unit. Under such circumstances, the General Partner is entitled to receive Incentive Distribution Rights.
On November 2, 2016, we announced a $1.77 cash distribution per common unit, payable on November 30, 2016 to holders of record as of November 15, 2016. In the third quarter of 2016, we exceeded the cumulative MQD amounts and will distribute Available Cash as summarized in the following table:

The General Partner is required to remit the majority of cash distributions it receives from the Partnership, in excess of its 1% Partnership equity interest, to an affiliated company.
General Partner Option to Effect Mandatory Redemption of Partnership Units
At September 30, 2016, the General Partner and its affiliates owned 75.3% of our outstanding units. When not more than 25% of our issued and outstanding units are held by non-affiliates of the General Partner, as was the case at September 30, 2016, we, at the General Partner's sole discretion, may call or assign to the General Partner or its affiliates, our right to acquire all, but not less than all, such outstanding units held by non-affiliated persons. If the General Partner elects to acquire all outstanding units, we are required to give at least 30 but not more than 60 days' notice of our decision to purchase the outstanding units. The purchase price per unit will be the greater of (1) the average of the previous 20 trading days' closing prices as of the date five days before the purchase is announced or (2) the highest price paid by the General Partner or any of its affiliates for any unit within the 90 days preceding the date the purchase is announced.

Derivatives
We purchase natural gas at market prices to meet production requirements at our manufacturing facility. Natural gas prices are volatile, and our natural gas acquisition policy allows us to establish derivative positions that are associated with anticipated natural gas requirements. The derivatives that we use are primarily natural gas fixed price swaps and options traded in the over-the-counter markets.
Natural gas derivatives involve the risk of dealing with counterparties and their ability to meet the terms of the contracts. The counterparties to our natural gas derivatives are multi-national commercial banks, other major financial institutions and large energy companies. For derivatives that are in net asset positions, we are exposed to credit loss from nonperformance by the counterparties. Credit risk is controlled through the use of multiple counterparties, credit limits, credit monitoring procedures, cash collateral requirements and master netting arrangements.
Contractual Obligations
At September 30, 2016, there were no material changes to the Partnership's contractual obligations, critical accounting policies or off-balance sheet arrangements presented in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our 2015 Annual Report.
Proposed Internal Revenue Service Regulation Impacting Master Limited Partnerships
We are a master limited partnership (MLP). Partnerships are generally not subject to federal income tax, although publicly traded partnerships (such as TNCLP) are treated as corporations for federal income tax purposes and therefore are subject to federal income tax, unless at least 90% of the partnership's gross income is "qualifying income" as defined in Section 7704 of the Internal Revenue Code of 1986, as amended, and the partnership is not required to register as an investment company under the Investment Company Act of 1940. As we currently satisfy the requirements to be treated as a partnership for federal income tax purposes, no federal income taxes are paid by the Partnership.
On May 6, 2015, the Internal Revenue Service (IRS) published proposed regulations on the types of income and activities that constitute or generate qualifying income of an MLP. The proposed regulations would have the effect of limiting the types of income and activities that qualify under the MLP rules, subject to certain transition provisions. The IRS proposed regulations include certain processing or refining and transportation activities with respect to any mineral or natural resource (including fertilizer) as activities that generate qualifying income, but the proposed regulations reserve on specific proposals regarding fertilizer-related activities. Any change in the federal income tax treatment of income from fertilizer-related activities as qualifying income could have a material impact on the taxation of the Partnership and could have a material adverse impact on unitholder distributions. We continue to monitor these IRS regulatory activities.
Magellan Ammonia Pipeline Outage
CF Industries utilizes an ammonia pipeline that is owned and operated by Magellan Midstream Partners L.P. (Magellan) to transport ammonia from our Verdigris, Oklahoma production complex to certain of their distribution facilities and customers. In October 2016, an ammonia release from the Magellan pipeline was discovered that resulted in the complete shutdown of the pipeline until such repairs can be made as are required by regulators. CF Industries has alternative barge, rail and truck shipping options available to ship the ammonia it purchases from us, but each option will result in increased shipping costs as compared to utilization of the Magellan pipeline which may impact the selling price that we realize. We cannot estimate at this time the duration of the pipeline shutdown or its potential financial impact on us.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
We are exposed to the impact of changes in the price of natural gas which we use in the manufacture of our nitrogen fertilizer products. Because natural gas prices are volatile, we manage the risk of changes in natural gas prices through the use of derivative financial instruments.
The derivative instruments that we use are primarily natural gas fixed price swaps and options. These contracts settle using NYMEX futures prices, which represent the basis for fair value at any given time. The derivatives are traded in months forward and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods.
As of September 30, 2016 and December 31, 2015, we had open derivative contracts for 36.9 million MMBtus and 59.6 million MMBtus, respectively, of natural gas. A $1.00 per MMBtu increase in the forward curve prices of natural gas as of September 30, 2016, would result in a favorable change in the fair value of these derivative positions by $34.0 million, and a $1.00 per MMBtu decrease would change their fair value unfavorably by $34.0 million.
ITEM 4.    CONTROLS AND PROCEDURES.
(a)    Disclosure Controls and Procedures.    TNGP's management, with the participation of TNGP's Principal Executive Officer and Principal Financial Officer, has evaluated the effectiveness of the Partnership's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) as of the end of the period covered by this report. Based on such evaluation, TNGP's Principal Executive Officer and Principal Financial Officer have concluded that, as of the end of such period, the Partnership's disclosure controls and procedures are effective in (i) ensuring that information required to be disclosed by the Partnership in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms and (ii) ensuring that information required to be disclosed by the Partnership in the reports that it files or submits under the Exchange Act is accumulated and communicated to TNGP's management, including TNGP's Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
(b)    Internal Control Over Financial Reporting.    There have not been any changes in the Partnership's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2016 that have materially affected, or are reasonably likely to materially affect, the Partnership's internal control over financial reporting.

PART II. OTHER INFORMATION
ITEM 1A.    RISK FACTORS.
Set forth below is an update to the risk factors previously disclosed in our Annual Report on Form 10-K filed on February 25, 2016 under "Risk Factors-Risks Related to Our Business.” We do not believe that there have been any material changes to the risk factors previously disclosed in our Annual Report on Form 10-K filed on February 25, 2016 under "Risk Factors-Risks Related to Our Partnership Structure" or "Risk Factors-Tax Risks to Our Common Unitholders." In addition to the other information contained herein and in our most recent periodic reports filed with the SEC, including our Annual Report on Form 10-K filed on February 25, 2016, you should carefully consider our risk factors disclosure before deciding to invest in TNCLP’s common units. These risks and uncertainties could materially and adversely affect our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
RISKS RELATED TO OUR BUSINESS
We are wholly dependent on our Verdigris manufacturing facility, and any operational disruption could result in a reduction of sales volumes and could cause us to incur substantial expenditures.
Our manufacturing operations, located at a single site in Verdigris, Oklahoma, are subject to significant operating hazards and interruptions. Any significant curtailment of production at one or more of our production units could result in materially reduced revenues and cash flows for the duration of any shutdown. Operations at our manufacturing facility could be curtailed or partially or completely shut down, temporarily or permanently, as the result of a number of circumstances, most of which are not within our control, such as unscheduled maintenance or catastrophic events like a major accident or fire, damage by severe weather or other natural disaster or sabotage or terrorist incidents. The manufacturing operations at our facility could also be subject to interruption if our ammonia storage facilities were to be removed from service due to damage from an accident or natural disaster or sabotage or terrorist incidents, or due to problems discovered during inspections associated with long-term maintenance or safety requirements.
Our business is cyclical, resulting in periods of industry oversupply during which our financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders tend to be negatively affected.
Historically, selling prices for our products have fluctuated in response to periodic changes in supply and demand conditions. Demand is affected by planted acreage and application rates, driven by population growth, changes in dietary habits and non-food usage of crops, such as the production of ethanol and other biofuels, among other things. Supply is affected by available capacity and operating rates, raw material costs and availability, government policies and global trade.
Periods of strong demand, high capacity utilization and increasing operating margins tend to stimulate global investment in production capacity. The construction of new nitrogen fertilizer manufacturing capacity in the industry, plus improvements to increase output from the existing production assets, increase nitrogen supply and affect the supply demand balance. In recent years, fertilizer producers, including CF Industries, have built new production facilities or expanded capacity of existing production assets, or announced plans to do so. In the current environment, global nitrogen fertilizer supply has increased faster than global nitrogen fertilizer demand, creating a global nitrogen fertilizer oversupply leading to lower nitrogen fertilizer selling prices. Lower global production costs driven by lower feedstock costs and foreign exchange rate changes, and reduced ocean freight costs, have further contributed to the lower priced environment.
Selling prices reached multi-year lows in the third quarter and first nine months of 2016. The average selling price for our products in the third quarter of 2016 was $174 per ton compared to $243 per ton for the third quarter of 2015, a decrease of 28%. The average selling price for our products in the first nine months of 2016 was $211 per ton compared to $286 per ton for the first nine months of 2015, a decline of 26%.
Additional production capacity is expected to come on line over the next twelve months, including capacity from CF Industries’ expansion projects which is expected to come fully on line by the end of 2016. We cannot predict the extent to which the current oversupply environment, global or local economic and financial conditions or changes in such conditions, or other factors may cause delays, cancellation or acceleration of other announced and/or ongoing projects.
We expect the lower priced environment to continue until global supply and demand become more balanced through a combination of continued demand growth and supply reductions as producers respond to lower realized margins by taking higher cost production facilities off line.

During periods of industry oversupply, our financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders tend to be affected negatively as the price at which we sell our products typically declines, resulting in possible reduced profit margins, write-downs in the value of our inventory and temporary or permanent curtailments of production. Our financial performance, the amount of our cash distributions, and the trading price for our common units have been negatively impacted by the lower selling prices resulting from the current global oversupply of nitrogen fertilizer. The period of time that these conditions will persist and the degree to which they will impact our business, financial condition, results of operations, cash flows and ability to pay cash distributions is uncertain.
Our products are global commodities, and we face intense global competition from other fertilizer producers.
We are subject to intense price competition from our competitors. Most fertilizers are global commodities, with little or no product differentiation, and customers make their purchasing decisions principally on the basis of delivered price and to a lesser extent on customer service and product quality.
We compete with many producers, including state-owned and government-subsidized entities. Consolidation in the industry has increased, and future consolidation is expected to further increase, the resources of several of our competitors. For example, in September 2016, our competitors Agrium Inc. and Potash Corporation of Saskatchewan Inc. announced plans to merge. Some of our competitors have greater total resources and are less dependent on earnings from fertilizer sales, which make them less vulnerable to industry downturns and better positioned to pursue new expansion and development opportunities. Furthermore, certain governments as owners of some of our competitors may be willing to accept lower prices and profitability on their products in order to support domestic employment or other political or social goals. Our competitive position could suffer to the extent we are not able to expand our own resources, either through investments in new or existing operations or through acquisitions, joint ventures or partnerships.
China, the world’s largest producer and consumer of nitrogen fertilizers, currently has significant capacity surplus and many high cost plants. As a result, the domestic nitrogen industry in China is operating at low rates. If Chinese government policy, devaluation of the Chinese renminbi or decreases in Chinese producers’ underlying costs such as the price of Chinese coal encourage increased production capacity utilization, the resulting export volume could adversely affect the balance between global supply and demand and may put downward pressure on global fertilizer prices, which could materially adversely affect our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
A decline in U.S. agricultural production or limitations on the use of our products for agricultural purposes could materially adversely affect the market for our products.
Conditions in the U.S. agricultural industry significantly impact our operating results. The U.S. agricultural industry can be affected by a number of factors, including weather patterns and field conditions, current and projected grain inventories and prices, domestic and international demand for U.S. agricultural products and U.S. and foreign policies regarding trade in agricultural products. These factors are outside of our control.
State and federal governmental policies, including farm and biofuel subsidies and commodity support programs, as well as the prices of fertilizer products, may also directly or indirectly influence the number of acres planted, the mix of crops planted and the use of fertilizers for particular agricultural applications. Ethanol production in the United States contributes significantly to corn demand, due in part to federal legislation mandating use of renewable fuels. An increase in ethanol production has led to an increase in the amount of corn grown in the United States and to increased fertilizer usage on both corn and other crops that have also benefited from improved farm economics. While the current Renewable Fuel Standard (RFS) encourages continued high levels of corn-based ethanol production, a continuing “food versus fuel” debate and other factors have resulted in calls to eliminate or reduce the renewable fuel mandate, or to eliminate or reduce corn-based ethanol as part of the renewable fuel mandate. This could have an adverse effect on corn-based ethanol production, planted corn acreage and fertilizer demand.
Developments in crop technology, such as nitrogen fixation, the conversion of atmospheric nitrogen into compounds that plants can assimilate, could also reduce the use of chemical fertilizers and adversely affect the demand for our products. In addition, from time to time various state legislatures have considered limitations on the use and application of chemical fertilizers due to concerns about the impact of these products on the environment. Any reduction in the demand for chemical fertilizer products, including any limitation on the use and application of chemical fertilizer, could affect the demand for our products, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.

TERRA NITROGEN COMPANY, L.P.

Our business is dependent on North American natural gas, the prices of which are subject to volatility.
Natural gas is the principal raw material used to produce nitrogen fertilizers. We use natural gas both as a chemical feedstock and as a fuel to produce ammonia, urea ammonium nitrate solution (UAN) and other nitrogen products. Natural gas comprises a significant portion of the total production cost of our products. The price of natural gas in North America has been volatile in recent years. During the first nine months of 2016, the daily closing price at the Henry Hub, the most heavily-traded natural gas pricing point in North America, reached a low of $1.49 per MMBtu on three consecutive days in March 2016 and a high of $3.14 per MMBtu on September 23, 2016. During the three year period ended September 30, 2016, the daily closing price at the Henry Hub reached a low of $1.49 per MMBtu on three consecutive days in March 2016 and a high of $7.94 per MMBtu on March 5, 2014.
Changes in the supply of and demand for natural gas can lead to periods of volatile natural gas prices. If high prices were to occur during a period of low fertilizer selling prices, it could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders. We sell all of our output of fertilizer products to CF Industries at prices determined based on market prices for our fertilizer products as defined in the General and Administrative Services and Product Offtake Agreement.
The price of natural gas in North America and worldwide has been volatile in recent years and has declined on average due in part to the development of significant natural gas reserves, including shale gas, and the rapid improvement in shale gas extraction techniques, such as hydraulic fracturing and horizontal drilling. Future production of natural gas from shale formations could be reduced by regulatory changes that restrict drilling or hydraulic fracturing or increase its cost or by reduction in oil exploration and development prompted by lower oil prices and resulting in production of less associated gas. Additionally, increased demand for natural gas, particularly in the Gulf Coast Region, due to increased industrial demand and increased natural gas exports could result in increased natural gas prices. If such reduced production or increased demand were to occur, or if other developments adversely impact the supply/demand balance for natural gas in the United States or elsewhere, natural gas prices could rise, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
Our operations are dependent upon raw materials provided by third parties, and any delay or interruption in the delivery of raw materials may adversely affect our business.
We use natural gas in the manufacture of fertilizers. We purchase the natural gas from third party suppliers. Our natural gas is transported by pipeline to our facility by third party transportation providers or through the use of facilities owned by third parties. Delays or interruptions in the delivery of natural gas may be caused by, among other things, severe weather or natural disasters, unscheduled downtime, labor difficulties, insolvency of our suppliers or their inability to meet existing contractual arrangements, deliberate sabotage and terrorist incidents, or mechanical failures. In addition, the transport of natural gas by pipeline is subject to additional risks, including delays or interruptions caused by capacity constraints, leaks or ruptures. Any delay or interruption in the delivery of natural gas, even for a limited period, could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
Our transportation and distribution activities rely on third party providers and are subject to environmental, safety and regulatory oversight. This exposes us to risks and uncertainties beyond our control that may adversely affect our operations and exposes us to additional liability.
We rely on railroad, truck, pipeline, and river barge companies to transport raw materials to our manufacturing complex, to coordinate and deliver finished products into CF Industries’ distribution system and to ship finished products to CF Industries’ customers. We also lease rail cars in order to ship raw materials and finished products. These transportation operations, equipment and services are subject to various hazards, including adverse operating conditions on the inland waterway system, extreme weather conditions, system failures, work stoppages, delays, accidents such as spills and derailments and other accidents and operating hazards. Additionally, due to the aging infrastructure of certain bridges, roadways, rail lines, river locks, and equipment that our third party service providers utilize, we may experience delays in both the receipt of raw materials or the shipment of finished product while repairs, maintenance or replacement activities are conducted. Also, certain third party service providers, particularly railroads, have experienced periodic service slowdowns due to capacity constraints in their systems which impact the shipping times of our products.
These transportation operations, equipment and services are also subject to environmental, safety, and regulatory oversight. Due to concerns related to accidents, discharges or other releases of hazardous substances, terrorism or the potential use of fertilizers as explosives, local, state and federal governments could implement new regulations affecting the transportation of raw materials or finished products.

25

TERRA NITROGEN COMPANY, L.P.

If shipping of our products is delayed or we are unable to obtain raw materials as a result of these transportation companies’ failure to operate properly, or if new and more stringent regulatory requirements are implemented affecting transportation operations or equipment, or if there are significant increases in the cost of these services or equipment, our revenues and cost of operations could be adversely affected.
The railroad industry continues various efforts to limit the railroads’ potential liability stemming from the transportation of Toxic Inhalation Hazard materials, such as the anhydrous ammonia that we transport to and from our facilities. For example, various railroads have implemented tariffs that include provisions that purport to shift liability to shippers to the extent that liabilities arise from third parties with insufficient resources. These initiatives could materially and adversely affect operating expenses and potentially our ability to transport anhydrous ammonia and increase our liability for releases of our anhydrous ammonia while in the care, custody and control of the railroads, for which our insurance may be insufficient or unavailable. New regulations also could be implemented affecting the equipment used to ship our raw materials or finished products. Increases in transportation costs, or changes in such costs relative to transportation costs incurred by our competitors, and any railroad industry initiatives that may impact our ability to transport our products, could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
Our operations and the production and handling of our products involve significant risks and hazards. We are not fully insured against all potential hazards and risks incident to our business. Therefore, our insurance coverage may not adequately cover our losses.
Our operations are subject to hazards inherent in the manufacture, transportation, storage and distribution of chemical products, including ammonia, which is highly toxic and corrosive. These hazards include: explosions; fires; severe weather and natural disasters; train derailments, collisions, vessel groundings and other transportation and maritime incidents; leaks and ruptures involving storage tanks, pipelines and rail cars; spills, discharges and releases of toxic or hazardous substances or gases; deliberate sabotage and terrorist incidents; mechanical failures; unscheduled plant downtime; labor difficulties and other risks. Some of these hazards can cause bodily injury and loss of life, severe damage to or destruction of property and equipment and environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties and liabilities.
We are currently insured under CF Industries’ property, business interruption, casualty and liability insurance policies, but we are not fully insured against all potential hazards and risks incident to our business. If we were to incur significant liability for which we were not fully insured, it could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders. CF Industries’ insurance policies are subject to various self-retentions, deductibles and limits under these insurance policies. The policies also contain exclusions and conditions that could have a material adverse impact on our ability to receive indemnification thereunder. CF Industries’ insurance policies are generally renewed annually. As a result of market conditions, insurance premiums, self-retentions and deductibles for certain insurance policies can increase substantially and, in some instances (including if CF Industries had fully utilized the purchased coverage), certain insurance may become unavailable or available only for reduced amounts of coverage. In addition, significantly increased costs could lead CF Industries to decide to reduce, or possibly eliminate, coverage. There can be no assurance that CF Industries or we will be able to buy and maintain insurance with adequate limits and reasonable pricing terms and conditions.
Cyber security risks could result in disruptions in business operations and adverse operating results.
The information management systems that we use are those provided by CF Industries, while we own the computer control systems that operate our plants. We rely on information technology and computer control systems in many aspects of our business, including internal and external communications, the management of our accounting, financial and supply chain functions and plant operations. Business and supply chain disruptions, plant and utility outages and information technology system and network disruptions due to cyber attacks could seriously harm our operations and materially adversely affect our operating results. Cyber security risks include attacks on information technology and infrastructure by hackers, damage or loss of information due to viruses, the unintended disclosure of confidential information, the misuse or loss of control over computer control systems, and breaches due to employee error. Our exposure to cyber security risks includes exposure through third parties on whose systems we place significant reliance for the conduct of our business. We have implemented security procedures and measures in order to protect our systems and information from being vulnerable to cyber attacks. We believe these measures and procedures are appropriate. However, we may not have the resources or technical sophistication to anticipate, prevent, or recover from rapidly evolving types of cyber attacks. Compromises to our information and control systems could have severe financial and other business implications.

TERRA NITROGEN COMPANY, L.P.

Adverse weather conditions may decrease demand for our fertilizer products, increase the cost of natural gas or materially disrupt our operations.
Weather conditions that delay or disrupt field work during the planting and growing seasons may cause agricultural customers to use different forms of nitrogen fertilizer, which may adversely affect demand for the forms that we sell or may impede farmers from applying our fertilizers until the following growing season, resulting in lower demand for our products.
Adverse weather conditions following harvest may delay or eliminate opportunities to apply fertilizer in the fall. Weather can also have an adverse effect on crop yields, which could lower the income of growers and impair their ability to purchase fertilizer from CF Industries’ customers. Our quarterly financial results can vary significantly from one year to the next due to weather-related shifts in planting schedules and purchasing patterns.
Weather conditions or, in certain cases, weather forecasts, also can affect the price of natural gas, the principal raw material used to make our nitrogen fertilizer products. Colder than normal winters and warmer than normal summers increase the demand for natural gas for power generation and for residential and industrial use, which can increase the cost and/or decrease the availability of natural gas. In addition, adverse weather events such as very low temperatures leading to well freeze-offs or hurricanes affecting the Gulf of Mexico coastal states can impact the supply of natural gas and cause prices to rise.
We are subject to numerous environmental, health and safety laws, regulations and permitting requirements, as well as potential environmental liabilities, which may require us to make substantial expenditures.
We are subject to numerous environmental, health and safety laws and regulations in the United States, including laws and regulations relating to the generation and handling of hazardous substances and wastes; the cleanup of hazardous substance releases; the discharge of regulated substances to air or water; and the demolition of existing plant sites upon permanent closure. These laws include the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the Toxic Substances Control Act and various other federal, state and local laws.
As a fertilizer company working with chemicals and other hazardous substances, our business is inherently subject to spills, discharges or other releases of hazardous substances into the environment. Certain environmental laws, including CERCLA, impose joint and several liability, without regard to fault, for cleanup costs on persons who have disposed of or released hazardous substances into the environment. Given the nature of our business, we have incurred, are incurring currently, and are likely to incur periodically in the future, liabilities under CERCLA and other environmental cleanup laws at our facility, adjacent or nearby third-party facilities or offsite disposal locations. The costs associated with future cleanup activities that we may be required to conduct or finance may be material. Additionally, we may become liable to third parties for damages, including personal injury and property damage, resulting from the disposal or release of hazardous substances into the environment.
Violations of environmental, health and safety laws can result in substantial penalties, court orders to install pollution-control equipment, civil and criminal sanctions, permit revocations and facility shutdowns. Environmental, health and safety laws change rapidly and have tended to become more stringent over time. As a result, we have not always been and may not always be in compliance with all environmental, health and safety laws and regulations. We may be subject to more stringent enforcement of existing or new environmental, health and safety laws in the future. Additionally, future environmental, health and safety laws and regulations or reinterpretation of current laws and regulations may require us to make substantial expenditures. Our costs to comply with, or any liabilities under, these laws and regulations could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
From time to time, our production of anhydrous ammonia has resulted in accidental releases that have temporarily disrupted our manufacturing operations and resulted in liability for administrative penalties and claims for personal injury. To date, our costs to resolve these liabilities have not been material. However, we could incur significant costs if our liability coverage is not sufficient to pay for all or a large part of any judgments against us, or if our insurance carrier refuses coverage for these losses.
We hold numerous environmental and other governmental permits and approvals authorizing operations at our Verdigris facility. Expansion or modification of our operations is predicated upon securing necessary environmental or other permits or approvals. A decision by a government agency to deny or delay issuing a new or renewed regulatory material permit or approval, or to revoke or substantially modify an existing permit or approval, or a determination that we have violated a law or permit as a result of a governmental inspection of our facility could have a material adverse effect on our ability to continue

27

TERRA NITROGEN COMPANY, L.P.

operations at the Verdigris facility and on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders. On October 1, 2015, the EPA released a final regulation lowering the national ambient air quality standard for ozone. Ozone attainment designations are expected by October 2017, and this action is expected to result in additional areas of the country being classified as being in nonattainment with the ozone standard and subject to more stringent permitting requirements, which in turn could make it much more difficult and expensive to obtain permits to construct new facilities or expand our existing operations.
Future regulatory restrictions on greenhouse gas emissions in the jurisdictions in which we operate could materially adversely affect our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
We are subject to greenhouse gas (GHG) regulations. There are substantial uncertainties as to the nature, stringency and timing of any future GHG regulations. On December 12, 2015, 195 countries adopted by consensus a new international agreement known as the Paris Agreement. The Paris Agreement is intended to provide a framework pursuant to which the parties to the agreement will attempt to hold the increase in global average temperatures to below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. The Paris Agreement has been ratified by the United States and will go into effect in November 2016. The Paris Agreement could result in more aggressive efforts to reduce GHG emissions. More stringent GHG limitations, if they are enacted, are likely to have a significant impact on us, because our production facility emits GHGs such as carbon dioxide and nitrous oxide and because natural gas, a fossil fuel, is a primary raw material used in our nitrogen production process. Regulation of GHGs may require us to make changes in our operating activities that would increase our operating costs, reduce our efficiency, limit our output, require us to make capital improvements to our facilities, increase our costs for or limit the availability of energy, raw materials or transportation, or otherwise materially adversely affect our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders. In addition, to the extent that GHG restrictions are not imposed in countries where our competitors operate or are less stringent than regulations that may be imposed in the United States, our competitors may have cost or other competitive advantages over us.
Our operating results fluctuate due to seasonality.
The fertilizer business is seasonal. The degree of seasonality of our business can change significantly from year to year due to conditions in the agricultural industry and other factors. The strongest demand for fertilizer products occurs during the spring planting season, with a second period of strong demand following the fall harvest. Wholesale buyers generally build inventories during the low demand periods of the year to ensure timely product availability during the peak sales seasons. Seasonality is greatest for ammonia due to the short application season and the limited ability of our customers and their customers to store significant quantities of this product. The seasonality of fertilizer demand results in sales volumes and net sales being the highest during the spring and working capital requirements being the highest just prior to the start of the spring planting season.
As a result of this seasonality, you will not be able to rely on our operating results in any particular period as an indication of our future performance. In addition, as a consequence of our seasonality, our distributions can be volatile, thus, affecting our liquidity and our available cash for distributions to unitholders, and will vary quarterly and annually.
Our business is subject to risks involving derivatives, including the risk that our hedging activities might not prevent losses.
We often utilize natural gas derivatives to hedge our financial exposure to the price volatility of natural gas, the principal raw material used in the production of nitrogen-based fertilizers. We have used fixed-price, physical purchase and sales contracts, futures, financial swaps and option contracts traded in the over-the-counter markets or on exchanges.
Our use of derivatives can result in volatility in reported earnings due to the unrealized mark-to-market adjustments that occur from changes in the value of the derivatives that do not qualify for, or to which we do not apply, hedge accounting. To the extent that our derivative positions lose value, we may be required to post collateral with our counterparties, adversely affecting our liquidity and our ability to pay cash distributions to unitholders.
Hedging arrangements are imperfect and unhedged risks will always exist. In addition, our hedging activities may themselves give rise to various risks that could adversely affect us. For example, we are exposed to counterparty credit risk when our derivatives are in a net asset position. The counterparties to our derivatives are multi-national commercial banks, major financial institutions or large energy companies. We monitor the derivative portfolio and credit quality of our counterparties and adjust the level of activity we conduct with individual counterparties as necessary. We also manage the

28

TERRA NITROGEN COMPANY, L.P.

credit risk through the use of multiple counterparties, credit limits, credit monitoring procedures, cash collateral requirements and master netting arrangements. However, our liquidity and cash available for distributions to unitholders could be negatively impacted by a counterparty default on settlement of one or more of our derivative financial instruments.
Our limited access to capital in a time of need could materially adversely impact our business.
We invest capital in our business to comply with environmental, health and safety regulations and policies, maintain our manufacturing assets, improve our production capabilities and capitalize on growth opportunities. The primary source of capital invested in our business is cash from operations. In the event that cash generated from operations is insufficient to fund capital investments, we would need to obtain additional funding in the form of loans or equity. Our ability to obtain such funding would be determined by market conditions at the time of the capital need. Our partnership structure and our reliance on a single manufacturing facility in Verdigris, Oklahoma could impede our ability to obtain such capital, which could materially adversely impact our business, financial condition, results of operations, liquidity and ability to pay cash distributions to unitholders.
Acts of terrorism and regulations to combat terrorism could negatively affect our business.
Like other companies with major industrial facilities, we may be the target of terrorist activities. Our Verdigris facility stores significant quantities of ammonia and other materials that can be dangerous if mishandled. Any damage to infrastructure facilities, such as electric generation, transmission and distribution facilities, or injury to employees, who could be direct targets or indirect casualties of an act of terrorism, may affect our operations. Any disruption of our ability to produce or distribute our products could result in a significant decrease in revenues and significant additional costs to replace, repair or insure our assets, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
In addition, due to concerns related to terrorism or the potential use of certain fertilizers as explosives, we are subject to various security laws and regulations. These security laws include the Maritime Transportation Security Act of 2002 and the Chemical Facilities Anti-Terrorism Standards regulation. In addition, President Obama issued Executive Order 13650 Improving Chemical Facility Safety and Security to improve chemical facility safety in coordination with owners and operators. Governmental entities could implement new or impose more stringent regulations affecting the security of our plants, terminals and warehouses or the transportation and use of fertilizers. These regulations could result in higher operating costs or limitations on the sale of our products and could result in significant unanticipated costs, lower revenues and reduced profit margins.
We are dependent on CF Industries and its employees for the success of our business.
We are dependent on CF Industries for our success in a number of respects. CF Industries, through a subsidiary, purchases all of the production from our manufacturing facility and, together with its affiliates, provides certain services to us, including staffing, benefits, human resources administration, production planning, manufacturing management, procurement, logistics, accounting, legal, risk management, investor relations and other general and administrative services. CF Industries and its wholly-owned subsidiaries have debt and debt service requirements and we currently do not. Although CF Industries is affected by most of the factors that affect us, a higher level of debt could put CF Industries at greater risk than us in the event business conditions deteriorate materially. Our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders might be adversely affected by financial difficulties at CF Industries, including default by CF Industries or its subsidiaries on their debt or their bankruptcy. Information regarding CF Industries can be obtained in the various filings with the SEC, including Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
Deterioration of global market and economic conditions could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to pay cash distributions to unitholders.
A slowdown of, or persistent weakness in, economic activity caused by a deterioration of global market and economic conditions could adversely affect our business in the following ways, among others: conditions in the credit markets could affect the ability of CF Industries’ customers and their customers to obtain sufficient credit to support their operations and the failure of certain key suppliers could increase our exposure to disruptions in supply or to financial losses. We also may experience declining demand and falling prices for some of our products due to CF Industries’ customers’ reluctance to replenish inventories. Changes in global economic conditions can arise suddenly and the full impact of such conditions can remain uncertain. For example, increased uncertainty in the wake of the referendum in the United Kingdom in June 2016, which resulted in a vote in favor of exiting the European Union (Brexit), has resulted in increased volatility in the global

29

TERRA NITROGEN COMPANY, L.P.

financial markets and the impact of Brexit on the global economy in 2016 and beyond remains uncertain. The overall impact of changes in global economic conditions on us is difficult to predict, and our business could be materially adversely impacted.
In addition, conditions in the international market for nitrogen fertilizers significantly influence our operating results. The international market for fertilizers is influenced by such factors as currency exchange rates, including the relative value of the U.S. dollar and its impact upon the cost of importing of nitrogen fertilizers into the United States, foreign agricultural policies, the existence of, or changes in, import or foreign currency exchange barriers in certain foreign markets and the laws and policies of the markets in which we operate that affect foreign trade and investment.
