NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1 . Background and Basis of Presentation

We are one of the largest manufacturers and distributors of nitrogen fertilizer and other nitrogen products in the world. Our principal customers are cooperatives, independent fertilizer distributors and industrial users. Our principal nitrogen fertilizer products are ammonia, granular urea and urea ammonium nitrate solution (UAN). Our other nitrogen products include ammonium nitrate (AN), diesel exhaust fluid (DEF), urea liquor, and aqua ammonia, which are sold primarily to our industrial customers. Our core market and distribution facilities are concentrated in the midwestern United States and other major agricultural areas of the United States and Canada. We also export nitrogen fertilizer products, primarily from our Donaldsonville, Louisiana manufacturing facility.

Prior to March 17, 2014, we also manufactured and distributed phosphate fertilizer products. Our principal phosphate products were diammonium phosphate (DAP) and monoammonium phosphate (MAP). On March 17, 2014, we completed the sale of our phosphate mining and manufacturing business (the "Transaction"), which was located in Florida, to The Mosaic Company (Mosaic) for approximately $1.4 billion in cash. The Transaction followed the terms of the definitive agreement executed in October 2013. The accounts receivable and accounts payable pertaining to the phosphate mining and manufacturing business and certain phosphate inventory held in distribution facilities were not sold to Mosaic in the Transaction and were settled in the ordinary course.

Upon closing the Transaction, we began to supply Mosaic with ammonia produced by our Point Lisas Nitrogen Limited (PLNL) joint venture. The contract to supply ammonia to Mosaic from our PLNL joint venture represents the continuation of a supply practice that previously existed between our former phosphate mining and manufacturing business and other operations of the Company. Prior to March 17, 2014, PLNL sold ammonia to us for use in the phosphate business and the cost was included in our production costs in the phosphate segment. Subsequent to the sale of the phosphate business, we now sell the PLNL-sourced ammonia to Mosaic. The revenue from these sales to Mosaic and the costs to purchase the ammonia from PLNL are now included in our ammonia segment. Our 50% share of the operating results of our PLNL joint venture continues to be included in our equity in earnings of operating affiliates in our consolidated statements of operations. Because of the significance of this continuing supply practice, in accordance with U.S. generally accepted accounting principles (GAAP), the phosphate mining and manufacturing business is not reported as discontinued operations in our consolidated statements of operations. See Note 3—Phosphate Business Disposition for additional information.

In the third quarter of 2014, we completed certain changes to our reporting structures and as a result, our reporting segments increased to the following five segments: ammonia, granular urea, UAN, other, and phosphate. The phosphate segment reflects the reported results of the phosphate business through March 17, 2014, plus the continuing sales of the phosphate inventory in the distribution network after March 17, 2014. The remaining phosphate inventory was sold in the second quarter of 2014; therefore, the phosphate segment does not have operating results subsequent to that quarter. The phosphate segment will continue to be included until the reporting of comparable period phosphate results ceases. Historical financial results have been restated to reflect the new segment structure on a comparable basis. See Note 18—Segment Disclosures .

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, 2014 , in accordance with U.S. GAAP 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 accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP 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 accompanying unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and related disclosures included in our 2014 Annual Report on Form 10-K filed with the SEC on February 26, 2015.

Table of Contents

The preparation of the unaudited interim consolidated financial statements requires us to make use of estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the unaudited consolidated financial statements and the reported revenues and expenses for the periods presented. Significant estimates and assumptions are used for, but are not limited to, net realizable value of inventories, environmental remediation liabilities, environmental and litigation contingencies, the cost of customer incentives, useful lives of property and identifiable intangible assets, the assumptions used in the evaluation of potential impairments of property, investments, identifiable intangible assets and goodwill, income tax and valuation reserves, allowances for doubtful accounts receivable, the measurement of the fair values of investments for which markets are not active, assumptions used in the determination of the funded status and annual expense of pension and postretirement employee benefit plans and the assumptions used in the valuation of stock-based compensation awards granted to employees.

All references to "CF Holdings," "the Company," "we," "us" and "our" refer to CF Industries Holdings, Inc. and its subsidiaries, except where the context makes clear that the reference is only to CF Industries Holdings, Inc. itself and not its subsidiaries. All references to "CF Industries" refer to CF Industries, Inc., a 100% owned subsidiary of CF Industries Holdings, Inc.

2 . New Accounting Standards

In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. This ASU is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) 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, information concerning the costs to obtain and fulfill a contract, including assets to be recognized, is to be disclosed. This ASU is effective for interim and annual reporting periods beginning after December 15, 2016. In April 2015, the FASB voted to propose to defer the effective date of this ASU by one year, with early adoption on the original effective date permitted. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.

3 . Phosphate Business Disposition

In March 2014, we completed the sale of our phosphate mining and manufacturing business to Mosaic (the "Transaction") pursuant to the terms of an Asset Purchase Agreement dated as of October 28, 2013 (the "Purchase Agreement"), among CF Industries Holdings, Inc., CF Industries, Inc. and Mosaic for approximately $1.4 billion in cash. During the first quarter of 2014, we recognized pre-tax and after-tax gains on the Transaction of $747.1 million and $461.0 million , respectively. Under the terms of the Purchase Agreement, the accounts receivable and accounts payable pertaining to the phosphate mining and manufacturing business and certain phosphate fertilizer inventory held in distribution facilities were not sold to Mosaic in the Transaction and were settled in the ordinary course. During the fourth quarter of 2014, based on the ordinary course settlement of certain transactions and certain adjustments that were made in accordance with the Purchase Agreement, we increased the recognized pre-tax and after-tax gains on the Transaction to $750.1 million and $462.8 million , respectively.

Upon closing the Transaction, we began to supply Mosaic with ammonia produced by our PLNL joint venture. The contract to supply ammonia to Mosaic from our PLNL joint venture represents the continuation of a supply practice that previously existed between our former phosphate mining and manufacturing business and other operations of the Company. Prior to March 17, 2014, PLNL sold ammonia to us for use in the phosphate business and the cost was included in our production costs in the phosphate segment. Subsequent to the sale of the phosphate business, we now sell the PLNL-sourced ammonia to Mosaic. The revenue from these sales to Mosaic and the costs to purchase the ammonia from PLNL are now included in our ammonia segment. Our 50% share of the operating results of our PLNL joint venture continues to be included in our equity in earnings of operating affiliates in our consolidated statements of operations.

Table of Contents

The phosphate mining and manufacturing business assets we sold in the Transaction include the Hardee County Phosphate Rock Mine; the Plant City Phosphate Complex; an ammonia terminal, phosphate warehouse and dock at the Port of Tampa; and the site of the former Bartow Phosphate Complex. In addition, Mosaic assumed certain liabilities related to the phosphate mining and manufacturing business, including responsibility for closure, water treatment and long-term maintenance and monitoring of the phosphogypsum stacks at the Plant City and Bartow complexes. Mosaic also received the value of the phosphate mining and manufacturing business's asset retirement obligation trust and escrow funds totaling approximately $200 million .

8 . Equity Method Investments

Equity method investments consist of the following:



	March 31, 2015		December 31, 2014
	(in millions)
Operating equity method investments	$	376.3	$	377.6
Non-operating equity method investments	477.2		483.9
Investments in and advances to affiliates	$	853.5	$	861.5

Operating Equity Method Investments

Our equity method investments included in operating earnings consist of: (1) a 50% ownership interest in Point Lisas Nitrogen Limited (PLNL), which operates an ammonia production facility in the Republic of Trinidad and Tobago; and (2) a 50% interest in an ammonia storage joint venture located in Houston, Texas. We include our share of the net earnings from these investments as an element of earnings from operations because these operations provide additional production and storage capacity to our operations and are integrated with our other supply chain and sales activities in the ammonia segment.

The combined results of operations and financial position for our operating equity method investments are summarized below:



	Three months ended March 31,
	2015		2014
	(in millions)
Summarized statement of operations information:
Net sales	$	75.2	$	75.2
Net earnings	$	23.0	$	24.8
Equity in earnings of operating affiliates	$	9.7	$	15.8



	March 31, 2015		December 31, 2014
	(in millions)
Summarized balance sheet information:
Current assets	$	91.0	$	111.2
Noncurrent assets	137.2		130.5
Total assets	$	228.2	$	241.7
Current liabilities	$	25.8	$	39.4
Noncurrent liabilities	21.0		22.0
Equity	181.4		180.3
Total liabilities and equity	$	228.2	$	241.7

The total carrying value of these investments as of March 31, 2015 was $376.3 million , which was $285.6 million more than our share of the affiliates' book value. The excess is primarily attributable to the purchase accounting impact of our acquisition of the investment in PLNL and reflects primarily the revaluation of property, plant and equipment, the value of an exclusive natural gas contract and goodwill. The increased basis for property, plant and equipment and the gas contract is being depreciated over a remaining period of approximately 19 years and 9 years , respectively. Our equity in earnings of operating affiliates is different from our ownership interest in income reported by the unconsolidated affiliates due to amortization of basis differences.

We have transactions in the normal course of business with PLNL reflecting our obligation to purchase 50% of the ammonia produced by PLNL at current market prices. Our ammonia purchases from PLNL totaled $29.6 million and $34.0 million for the three months ended March 31, 2015 and 2014 , respectively.

Table of Contents

Non-Operating Equity Method Investments

Our non-operating equity method investments consist of: (1) a 50% ownership interest in KEYTRADE AG (Keytrade), a fertilizer trading company headquartered near Zurich, Switzerland; and (2) a 50% ownership interest in GrowHow UK Limited (GrowHow), which operates nitrogen production facilities in the United Kingdom. We account for these investments as non-operating equity method investments, and exclude the net earnings of these investments in earnings from operations since these operations do not directly provide additional capacity to us, nor are these operations integrated within our supply chain.

The combined results of operations and financial position of our non-operating equity method investments are summarized below:



	Three months ended March 31,
	2015		2014
	(in millions)
Summarized statement of operations information:

Noncurrent liabilities	174.7		186.9
Equity	342.6		320.4
Total liabilities and equity	$	805.2	$	798.0

In conjunction with our investment in Keytrade, we provided financing to Keytrade in exchange for subordinated notes that mature on September 30, 2017 and bear interest at LIBOR plus 1.00 percent . As of March 31, 2015 and December 31, 2014 , the amount of the outstanding advances to Keytrade on our consolidated balance sheets was $12.4 million . For each of the three -month periods ended March 31, 2015 and 2014 , we recognized interest income on advances to Keytrade of approximately $0.1 million . The carrying value of our advances to Keytrade approximates fair value.

Excluding the advances to Keytrade, the carrying value of our non-operating equity method investments as of March 31, 2015 was $464.8 million , which was $293.5 million more than our share of the affiliates' book value. The excess is primarily attributable to the purchase accounting impact of our acquisition of GrowHow and reflects the revaluation of property, plant and equipment, identifiable intangibles and goodwill. The increased basis for property, plant and equipment and identifiable intangibles is being depreciated over remaining periods of up to 11 years . Our equity in earnings of non-operating affiliates—net of taxes is different than our ownership interest in their net earnings due to the amortization of basis differences.

As of March 31, 2015 , the amount of our consolidated retained earnings that represents our undistributed earnings of non-operating equity method investments is $22.5 million .

Cash Equivalents

As of March 31, 2015 and December 31, 2014 , our cash equivalents consisted primarily of U.S. and Canadian government obligations and money market mutual funds that invest in U.S. government obligations and other investment-grade securities.

Restricted Cash

We maintain a cash account for which the use of the funds is restricted. The restricted cash account as of March 31, 2015 and December 31, 2014 was put in place to satisfy certain requirements included in our engineering and procurement services contract for our capacity expansion projects. Under the terms of this contract, we are required to grant an affiliate of ThyssenKrupp Industrial Solutions, formerly ThyssenKrupp Uhde, a security interest in a restricted cash account and maintain a cash balance in that account equal to the cancellation fees for procurement services and equipment that would arise if we were to cancel the projects.

Derivative Instruments

The derivative instruments that we use are primarily natural gas options, natural gas fixed price swaps and foreign currency forward contracts traded in the over-the-counter (OTC) markets with multi-national commercial banks, other major financial institutions and large energy companies. The natural gas derivatives are traded in months forward and settlements are scheduled to coincide with anticipated gas purchases during those future periods. The foreign currency derivative contracts held are for the exchange of a specified notional amount of currencies at specified future dates coinciding with anticipated foreign currency cash outflows associated with our Donaldsonville, Louisiana and Port Neal, Iowa capacity expansion projects. The natural gas derivative contracts settle using primarily NYMEX futures prices. 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. The currency derivatives are valued based on quoted market prices supplied by an industry-recognized independent third party. See Note 14—Derivative Financial Instruments for additional information.

Nonqualified Employee Benefit Trusts

We maintain trusts associated with certain deferred compensation related nonqualified employee benefits. The investments are accounted for as available-for-sale securities. The fair values of the trusts are based on daily quoted prices representing the net asset values (NAV) of the investments. These trusts are included on our consolidated balance sheets in other assets.

Financial Instruments

The carrying amounts and estimated fair values of our financial instruments are as follows:



	March 31, 2015				December 31, 2014
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(in millions)
Long-term debt	$	4,592.5	$	5,086.6	$	4,592.5	$	4,969.3

Table of Contents

The fair value of our long-term debt was based on quoted prices for identical or similar liabilities in markets that are not active or valuation models in which all significant inputs and value drivers are observable and, as a result, are classified as Level 2 inputs.

The carrying amounts of cash and cash equivalents, as well as instruments included in other current assets and other current liabilities that meet the definition of financial instruments, approximate fair values because of their short-term maturities.

10 . Income Taxes

Our income tax provision for the three months ended March 31, 2015 was $112.7 million on pre-tax income of $333.7 million , or an effective tax rate of 33.8% , compared to an income tax provision of $413.2 million on pre-tax income of $1,130.1 million , or an effective tax rate of 36.6% , for the three months ended March 31, 2014 . Our effective tax rate was lower in the three months ended March 31, 2015 principally due to the higher effective tax rate on the gain related to the sale of our phosphate mining and manufacturing business in March 2014.

Our effective tax rate based on pre-tax earnings differs from our effective tax rate based on pre-tax earnings exclusive of the noncontrolling interest, as our consolidated income tax provision does not include a tax provision on the earnings attributable to the noncontrolling interest in Terra Nitrogen Company, L.P. (TNCLP), which does not record an income tax provision.

Our unrecognized tax benefits are $135.8 million as of March 31, 2015 of which approximately $97.0 million would impact our effective tax rate if these unrecognized tax benefits were to be recognized in the future.

11 . Interest Expense

Details of interest expense are as follows:



	Three months ended March 31,
	2015			2014
	(in millions)
Interest on borrowings ⁽¹⁾	$	63.5		$	47.9

12 . Financing Agreements

Credit Agreement

CF Holdings, as a guarantor, and CF Industries, as borrower, entered into a $500.0 million senior unsecured credit agreement, dated May 1, 2012 (the Credit Agreement), which provided for a revolving credit facility of up to $500.0 million with a maturity of five years . On April 22, 2013 , the Credit Agreement was amended and restated to increase the credit facility from $500.0 million to $1.0 billion and extend its maturity to May 1, 2018 . On March 20, 2015 , the Credit Agreement was further amended and restated to increase the credit facility from $1.0 billion to $1.5 billion and extend its maturity to March 20, 2020 .

Borrowings under the Credit Agreement bear interest at a variable rate based on an applicable margin over LIBOR or a base rate and may be used for working capital, capital expenditures, acquisitions, share repurchases and other general corporate purposes. The Credit Agreement requires that the Company maintain a minimum interest coverage ratio and not exceed a maximum total leverage ratio, and includes other customary terms and conditions, including customary events of default and covenants.

All obligations under the Credit Agreement are unsecured. Currently, CF Holdings is the only guarantor of CF Industries' obligations under the Credit Agreement. Certain of CF Industries' domestic subsidiaries would be required to become guarantors under the Credit Agreement if such subsidiary were to guarantee other debt of the Company or CF Industries in excess of $450.0 million . Currently, no such subsidiary guarantees any debt.

As of March 31, 2015 , there was $1,495.1 million of available credit under the Credit Agreement (net of outstanding letters of credit of $4.9 million ), and there were no borrowings outstanding as of March 31, 2015 or December 31, 2014 .

Senior Notes

Long-term debt presented on our consolidated balance sheets as of March 31, 2015 and December 31, 2014 consisted of the following:



	March 31, 2015		December 31, 2014
	(in millions)
Unsecured senior notes:
6.875% due 2018	$	800.0	$	800.0
7.125% due 2020	800.0		800.0
3.450% due 2023	749.4		749.4
5.150% due 2034	746.2		746.2
4.950% due 2043	748.8		748.8
5.375% due 2044	748.1		748.1
	4,592.5		4,592.5
Less: Current portion	—		—
Net long-term debt	$	4,592.5	$	4,592.5

Under the indentures (including the applicable supplemental indentures) governing the senior notes identified in the table above, each series of senior notes is guaranteed by CF Holdings. Interest is paid semiannually and the senior notes are redeemable at our option, in whole at any time or in part from time to time, at specified make-whole redemption prices. The indentures governing the senior notes contain customary events of default and covenants that limit, among other things, the ability of CF Holdings and its subsidiaries, including CF Industries, to incur liens on certain properties to secure debt.

If a Change of Control occurs together with a Ratings Downgrade (as both terms are defined under the indentures governing the senior notes), CF Industries would be required to offer to repurchase each series of senior notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest. In addition, in the event that a subsidiary of ours, other than CF Industries, becomes a borrower or a guarantor under the Credit Agreement (or any renewal, replacement or refinancing thereof), such subsidiary would be required to become a guarantor of the senior notes, provided that such requirement will no longer apply with respect to the senior notes due in 2023, 2034, 2043 and 2044 following the repayment of the senior notes due in 2018 and 2020 or the subsidiaries of ours, other than CF Industries, otherwise becoming no longer subject to such a requirement to guarantee the senior notes due in 2018 and 2020.

13 . Noncontrolling Interest

Terra Nitrogen Company, L.P. (TNCLP) is a master limited partnership that owns a nitrogen manufacturing facility in Verdigris, Oklahoma. We own an aggregate 75.3% of TNCLP through general and limited partnership interests. Outside investors own the remaining 24.7% of the limited partnership. For financial reporting purposes, the assets, liabilities and earnings of the partnership are consolidated into our financial statements. The outside investors' limited partnership interests in the partnership are recorded in noncontrolling interest in our consolidated financial statements. The noncontrolling interest represents the noncontrolling unitholders' interest in the earnings and equity of TNCLP. An affiliate of CF Industries is required to purchase all of TNCLP's fertilizer products at market prices as defined in the Amendment to the General and Administrative Services and Product Offtake Agreement, dated September 28, 2010.

TNCLP makes cash distributions to the general and limited partners based on formulas defined within its Agreement of Limited Partnership. Cash available for distribution is defined in the agreement 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 increases 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. Cash distributions to the limited partners and general partner vary depending on the extent to which the cumulative distributions exceed certain target threshold levels set forth in the Agreement of Limited Partnership.

In each of the applicable quarters of 2015 and 2014 , the minimum quarterly distributions were satisfied, which entitled us, as the general partner, to receive increased distributions on our general partner interests as provided for in the Agreement of Limited Partnership. The earnings attributed to our general partner interest in excess of the threshold levels for the three months ended March 31, 2015 and 2014 , were $20.3 million and $40.5 million , respectively.

As of March 31, 2015 , Terra Nitrogen GP Inc. (TNGP), the general partner of TNCLP (and an indirect wholly-owned subsidiary of CF Industries), and its affiliates owned 75.3% of TNCLP's outstanding units. When not more than 25% of TNCLP's issued and outstanding units are held by non-affiliates of TNGP, TNCLP, at TNGP's sole discretion, may call, or assign to TNGP or its affiliates, TNCLP's right to acquire all such outstanding units held by non-affiliated persons. If TNGP elects to acquire all outstanding units, TNCLP is required to give at least 30 but not more than 60 days' notice of TNCLP's 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 TNGP or any of its affiliates for any unit within the 90 days preceding the date the purchase is announced.

14 . Derivative Financial Instruments

We use derivative financial instruments to reduce our exposure to changes in commodity prices and foreign currency exchange rates.

Commodity Price Risk Management

Natural gas is the largest and most volatile component of the manufacturing cost for nitrogen-based products. We manage the risk of changes in natural gas prices primarily through the use of derivative financial instruments covering periods of generally less than 18 months . The derivatives that we use are primarily natural gas options and natural gas fixed price swaps traded in the OTC markets. These natural gas derivatives settle using primarily a NYMEX futures price index, which represents the basis for fair value at any given time. We enter into natural gas derivative contracts with respect to natural gas to be consumed by us in the future, and settlements 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 natural gas price risk, but without the application of hedge accounting. As a result, changes in fair value of these contracts are recorded in earnings.

As of March 31, 2015 and December 31, 2014 , we had open natural gas derivative contracts for 77.4 million MMBtus and 58.7 million MMBtus, respectively. For the three months ended March 31, 2015 , we used derivatives to cover approximately 93% of our natural gas consumption.

Foreign Currency Exchange Rates

In the fourth quarter of 2012, our Board of Directors authorized a project to construct new ammonia and urea/UAN plants at our Donaldsonville, Louisiana complex and new ammonia and urea plants at our Port Neal, Iowa complex. A portion of the capacity expansion project costs are euro-denominated. In order to manage our exposure to changes in the euro to U.S. dollar currency exchange rates, we have hedged our projected euro-denominated payments through the fourth quarter of 2015 using foreign currency forward contracts. Certain of these contracts were originally designated as cash flow hedges.

As of December 31, 2013, we de-designated the remaining cash flow hedges related to our capacity expansion projects. As of March 31, 2015 and December 31, 2014 , the notional amount of our open foreign currency derivatives was €144.0 million and €209.0 million , respectively. None of these open foreign currency derivatives were designated as hedging instruments for accounting purposes.

As of March 31, 2015 , the remaining pre-tax accumulated other comprehensive income balance of $7.4 million related to the de-designated cash flow hedges is expected to be reclassified into income over the depreciable lives of the property, plant and equipment associated with the capacity expansion projects. We expect that the amounts to be reclassified within the next twelve months will be insignificant. See Note 16—Accumulated Other Comprehensive Income (Loss) , for further information.

As of March 31, 2015 and December 31, 2014 , the aggregate fair value of the derivative instruments with credit-risk-related contingent features in a net liability position was $38.3 million and $47.1 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. At both March 31, 2015 and December 31, 2014 , we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with certain of our International Swaps and Derivatives Association (ISDA) agreements generally provide us and our counterparties the right to set off collateral against amounts owing under the ISDA agreements upon the occurrence of a default or a specified termination event.

15 . Treasury Stock

Our Board of Directors has authorized certain programs to repurchase shares of our common stock. Each of these programs is consistent in that repurchases may be made from time to time in the open market, through privately-negotiated transactions, through block transactions or otherwise. The manner, timing and amount of repurchases are determined by our management based on the evaluation of market conditions, stock price and other factors.

In the third quarter of 2012, our Board of Directors authorized a program to repurchase up to $3.0 billion of the common stock of CF Holdings through December 31, 2016 (the 2012 Program). The repurchases under this program were completed in the second quarter of 2014. On August 6, 2014, our Board of Directors authorized a program to repurchase up to $1.0 billion of the common stock of CF Holdings through December 31, 2016 (the 2014 Program).

The following table summarizes the share repurchases under the 2014 Program and the 2012 Program:

Litigation

West Fertilizer Co.

On April 17, 2013, there was a fire and explosion at the West Fertilizer Co. fertilizer storage and distribution facility in West, Texas. According to published reports, 15 people were killed and approximately 200 people were injured in the incident, and the fire and explosion damaged or destroyed a number of homes and buildings around the facility. We have been named as defendants along with other companies in lawsuits filed in 2013 and 2014 in the District Court of McLennan County, Texas by the City of West, individual residents of the County and other parties seeking recovery for damages allegedly sustained as a result of the explosion. The cases have been consolidated for discovery and pretrial proceedings before Judge Jim Meyer in the District Court of McLennan County under the caption "In re: West Explosion Cases." The two-year statute of limitations expired on April 17, 2015. As of that date, over 400 plaintiffs had filed claims, including at least 9 entities, 325 individuals, and 80 insurance companies. Plaintiffs allege various theories of negligence, strict liability, breach of warranty and assault under Texas law. Although we do not own or operate the facility or directly sell our products to West Fertilizer Co., products we have manufactured and sold to others have been delivered to the facility and may have been stored at the West facility at the time of the incident.

Fact and expert witness discovery continues about the circumstances surrounding the April 17, 2013 fire and explosion. On April 2, 2015, the Court entered a revised scheduling order requiring the parties to file dispositive Motions for Summary Judgment by May 15, 2015, with subsequent briefing and hearings to occur into August 2015. Any mediation between the parties must be completed by August 17, 2015. The first three cases are scheduled to begin trial on October 12, 2015. We believe we have strong legal and factual defenses and intend to continue defending ourselves vigorously in the pending lawsuits.

Other Litigation

From time to time, we are subject to ordinary, routine legal proceedings related to the usual conduct of our business, including proceedings regarding public utility and transportation rates, environmental matters, taxes and permits relating to the operations of our various plants and facilities. Based on the information available as of the date of this filing, we believe that the ultimate outcome of these routine matters will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Louisiana Environmental Matters

Clean Air Act—Section 185 Fee

Our Donaldsonville nitrogen complex is located in a five-parish region near Baton Rouge, Louisiana that, as of 2005, was designated as being in "severe" nonattainment with respect to the national ambient air quality standard (NAAQS) for ozone (the 1-hour ozone standard) pursuant to the Federal Clean Air Act (the Act). Section 185 of the Act requires states, in their state implementation plans, to levy a fee (Section 185 fee) on major stationary sources (such as the Donaldsonville complex) located in a severe nonattainment area that did not meet the 1-hour ozone standard by November 30, 2005. The fee was to be assessed for each calendar year (beginning in 2006) until the area achieved compliance with the ozone NAAQS.

Prior to the imposition of Section 185 fees, the Environmental Protection Agency (EPA) adopted a new ozone standard (the 8-hour ozone standard) and rescinded the 1-hour ozone standard. The Baton Rouge area was designated as a "moderate" nonattainment area with respect to the 8-hour ozone standard. However, because Section 185 fees had never been assessed prior to the rescission of the 1-hour ozone standard (rescinded prior to the November 30, 2005 ozone attainment deadline), the EPA concluded in a 2004 rulemaking implementing the 8-hour ozone standard that the Act did not require states to assess Section 185 fees. As a result, Section 185 fees were not assessed against us and other companies located in the Baton Rouge area.

In 2006, the federal D.C. Circuit Court of Appeals rejected the EPA's position and held that Section 185 fees were controls that must be maintained and fees should have been assessed under the Act. In January 2008, the U.S. Supreme Court declined to accept the case for review, making the appellate court's decision final.

Table of Contents

In July 2011, the EPA approved a revision to Louisiana's air pollution program that eliminated the requirement for Baton Rouge area companies to pay Section 185 fees, based on Baton Rouge's ultimate attainment of the 1-hour standard through permanent and enforceable emissions reductions. EPA's approval of the Louisiana air program revision became effective on August 8, 2011. However, a recent decision by the federal D.C. Circuit Court of Appeals struck down a similar, but perhaps distinguishable, EPA guidance document regarding alternatives to Section 185 fees. At this time, the viability of EPA's approval of Louisiana's elimination of Section 185 fees is uncertain. Regardless of the approach ultimately adopted by the EPA, we expect that it is likely to be challenged by the environmental community, the states, and/or affected industries. Therefore, the costs associated with compliance with the Act cannot be determined at this time, and we cannot reasonably estimate the impact on our consolidated financial position, results of operations or cash flows.

Furthermore, the area has seen significant reductions in ozone levels, attributable to federal and state regulations and community involvement. Preliminary ozone design values computed for the Baton Rouge nonattainment area suggest the area has achieved attainment with the 2008 8-hour ozone standard. A determination from EPA was issued on April 4, 2014 indicating that the Baton Rouge area is currently attaining the 2008 8-hour ozone standard. The determination is based on a recent review of air quality data from 2011-2013. Additional revisions to the ozone NAAQS, like the proposed rule that would strengthen the ozone standard that was proposed on December 17, 2014, may affect the longevity and long-term consequences of this determination.

Clean Air Act Information Request

On February 26, 2009, we received a letter from the EPA under Section 114 of the Act requesting information and copies of records relating to compliance with New Source Review and New Source Performance Standards at the Donaldsonville facility. We have completed the submittal of all requested information. There has been no further contact from the EPA regarding this matter.

Florida Environmental Matters

On March 17, 2014, we completed the sale of our phosphate mining and manufacturing business, which was located in Florida, to Mosaic. Pursuant to the terms of the Purchase Agreement, Mosaic has assumed the following environmental matters and we have agreed to indemnify Mosaic with respect to losses arising out of the matters below, subject to a maximum indemnification cap and the other terms of the Purchase Agreement.

Clean Air Act Notice of Violation

We received a Notice of Violation (NOV) from the EPA by letter dated June 16, 2010, alleging that we violated the Prevention of Significant Deterioration (PSD) Clean Air Act regulations relating to certain projects undertaken at the former Plant City, Florida facility's sulfuric acid plants. This NOV further alleges that the actions that are the basis for the alleged PSD violations also resulted in violations of Title V air operating permit regulations. Finally, the NOV alleges that we failed to comply with certain compliance dates established by hazardous air pollutant regulations for phosphoric acid manufacturing plants and phosphate fertilizer production plants. We had several meetings with the EPA with respect to this matter prior to the sale of the phosphate mining and manufacturing business in March 2014. We do not know at this time if this matter will be settled prior to initiation of formal legal action.

We cannot estimate the potential penalties, fines or other expenditures, if any, that may result from the Clean Air Act NOV and, therefore, we cannot determine if the ultimate outcome of this matter will have a material impact on our consolidated financial position, results of operations or cash flows.

EPCRA/CERCLA Notice of Violation

By letter dated July 6, 2010, the EPA issued a NOV to us alleging violations of Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) in connection with the former Plant City facility. EPCRA requires annual reports to be submitted with respect to the use of certain toxic chemicals. The NOV also included an allegation that we violated Section 304 of EPCRA and Section 103 of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) by failing to file a timely notification relating to the release of hydrogen fluoride above applicable reportable quantities. We not know at this time if this matter will be settled prior to initiation of formal legal action.

We do not expect that penalties or fines, if any, that may arise out of the EPCRA/CERCLA matter will have a material impact on our consolidated financial position, results of operations or cash flows.

Table of Contents

Other

CERCLA/Remediation Matters

From time to time, we receive notices from governmental agencies or third parties alleging that we are a potentially responsible party at certain cleanup sites under CERCLA or other environmental cleanup laws. In 2011, we received a notice from the Idaho Department of Environmental Quality (IDEQ) that alleged that we were a potentially responsible party for the cleanup of a former phosphate mine site we owned in the late 1950s and early 1960s located in Georgetown Canyon, Idaho. The current owner of the property and a former mining contractor received similar notices for the site. In 2014, we and the current property owner entered into a Consent Order with IDEQ and the U.S. Forest Service to conduct a remedial investigation and feasibility study of the site. We are not able to estimate at this time our potential liability, if any, with respect to the cleanup of the site. However, based on currently available information, we do not expect that any remedial or financial obligations to which we may be subject involving this or other cleanup sites will have a material adverse effect on our business, financial condition, results of operations or cash flows.

18 . Segment Disclosures

Our reporting segments consist of the following: ammonia, granular urea, UAN, other, and phosphate. These segments are differentiated by products, which are used differently by agricultural customers based on crop application, weather and other agronomic factors or by industrial customers based on their usage.

We sold our phosphate mining and manufacturing business during the first quarter of 2014. The phosphate segment reflects the reported results of the phosphate business through March 17, 2014, plus the continuing sales of the phosphate inventory in the distribution network after March 17, 2014. The remaining phosphate inventory was sold in the second quarter of 2014; therefore, the phosphate segment does not have operating results subsequent to that quarter. The phosphate segment will continue to be included until the reporting of comparable period phosphate results ceases. Upon selling the phosphate business, we began to supply Mosaic with ammonia produced by our PLNL joint venture. The contract to supply ammonia to Mosaic from our PLNL joint venture represents the continuation of a supply practice that previously existed between our former phosphate mining and manufacturing business and other operations of the Company. Prior to March 17, 2014, PLNL sold ammonia to us for use in the phosphate business and the cost was included in our production costs in the phosphate segment. Subsequent to the sale of the phosphate business, we now sell the PLNL-sourced ammonia to Mosaic. The revenue from these sales to Mosaic and costs to purchase the ammonia from PLNL are now included in our ammonia segment. Our 50% share of the operating results of our PLNL joint venture continues to be included in our equity in earnings of operating affiliates in our consolidated statements of operations. Because of the significance of this continuing supply practice, in accordance with U.S. GAAP, the phosphate mining and manufacturing business is not reported as discontinued operations in our consolidated statements of operations.

Our management uses gross margin to evaluate segment performance and allocate resources. Total other operating costs and expenses (consisting of selling, general and administrative expenses and other operating—net) and non-operating expenses (interest and income taxes) are centrally managed and are not included in the measurement of segment profitability reviewed by management.

Our assets, with the exception of goodwill, are not monitored by or reported to our Chief Operating Decision Maker by segment; therefore, we do not present total assets by segment. Goodwill by segment is presented in Note 7—Goodwill and Other Intangible Assets .

Segment data for sales, cost of sales and gross margin for the three months ended March 31, 2015 and 2014 are presented in the tables below.

19 . Condensed Consolidating Financial Statements

The following condensed consolidating financial statements are presented in accordance with SEC Regulation S-X Rule 3-10, Financial statements of guarantors and issuers of guaranteed securities registered or being registered , and relates to the senior notes (the Notes) issued by CF Industries, Inc. (CF Industries), a 100% owned subsidiary of CF Industries Holdings, Inc. (Parent), described in Note 12—Financing Agreements , and the full and unconditional guarantee of such Notes by Parent and to debt securities of CF Industries, and the full and unconditional guarantee thereof by Parent, that may be offered and sold from time to time under the registration statement on Form S-3 filed by Parent and CF Industries with the SEC on April 22, 2013. In the event that a subsidiary of Parent, other than CF Industries, becomes a borrower or a guarantor under the Credit Agreement (or any renewal, replacement or refinancing thereof), such subsidiary would be required to become a guarantor of the Notes, provided that such requirement will no longer apply with respect to the Notes due in 2023, 2034, 2043 and 2044 following the repayment of the Notes due in 2018 and 2020 or the subsidiaries of Parent, other than CF Industries, otherwise becoming no longer subject to such a requirement to guarantee the Notes due in 2018 and 2020. As of March 31, 2015 , none of such subsidiaries of Parent was, or was required to be, a guarantor to the Notes. For purposes of the presentation of condensed consolidating financial information, the subsidiaries of Parent other than CF Industries are referred to as the Other Subsidiaries.

Presented below are condensed consolidating statements of operations and statements of cash flows for Parent, CF Industries and the Other Subsidiaries for the three months ended March 31, 2015 and 2014 , and condensed consolidating balance sheets for Parent, CF Industries and the Other Subsidiaries as of March 31, 2015 and December 31, 2014 . The condensed consolidating financial statements presented below are not necessarily indicative of the financial position, results of operations, comprehensive income or cash flows of Parent, CF Industries or the Other Subsidiaries on a stand-alone basis.

In these condensed consolidating financial statements, investments in subsidiaries are presented under the equity method, in which our investments are recorded at cost and adjusted for our ownership share of a subsidiary's cumulative results of operations, distributions and other equity changes, and the eliminating entries reflect primarily intercompany transactions such as sales, accounts receivable and accounts payable and the elimination of equity investments and earnings of subsidiaries.

Share Repurchases

In April 2015, we repurchased 0.5 million of the Company's common shares for $140.6 million as part of the $1.0 billion share repurchase program announced in the third quarter of 2014 (see Note 15—Treasury Stock ). Together with the 2.2 million shares repurchased through March 31, 2015, these repurchases bring the total repurchased shares to date under this program to 2.7 million for an aggregate expenditure of $750.0 million .

Proposed Internal Revenue Service Regulation Impacting Master Limited Partnerships

On May 6, 2015, the Internal Revenue Service (“IRS”) issued proposed regulations on the types of income and activities which constitute qualified income of a Master Limited Partnership (“MLP”). The proposed regulations would have the effect of limiting the types of income and activities which qualify under the MLP rules, subject to certain transition provisions. The IRS proposal specifically highlights companies that perform chemical processing and transformation activities as one of the focuses of the proposed changes, but the proposed regulations do not contain specific proposals regarding fertilizer-related activities. The proposed regulations reserve on the provisions relating to fertilizer activities.

The Company holds a 75.3% interest in Terra Nitrogen Company, L.P. (TNCLP), a publicly-traded MLP, which owns a fertilizer manufacturing complex in Verdigris, Oklahoma. Currently, no federal income taxes are paid by TNCLP due to its MLP status. Any change in the tax treatment of qualified income of fertilizer-related activities could have a material impact on the taxation of TNCLP and could have a material adverse impact on unit holder distributions for unit holders who would not be entitled to a dividends received deduction or other similar offsetting deduction. If TNCLP were taxed as a corporation, under current law, due to its current ownership interest, CF Industries Holdings would qualify for a partial dividends received deduction on the dividends received from TNCLP. Therefore, we would not expect this proposed change to have a material impact on the financial condition or results of operations of CF Industries Holdings. We will continue to monitor the IRS regulatory activities.

Overview of CF Holdings

Our Company

Prior to March 17, 2014, we also manufactured and distributed phosphate fertilizer products. Our principal phosphate products were diammonium phosphate (DAP) and monoammonium phosphate (MAP). On March 17, 2014, we completed the sale of our phosphate mining and manufacturing business (the "Transaction") to The Mosaic Company (Mosaic) pursuant to the terms of an Asset Purchase Agreement dated as of October 28, 2013 (the "Purchase Agreement"), among CF Industries Holdings, Inc., CF Industries and Mosaic for approximately $1.4 billion in cash. See the section titled Items Affecting Comparability of Results for further information on the Transaction and its impact.

Our principal assets include:


•	six nitrogen fertilizer manufacturing facilities located in: Donaldsonville, Louisiana (the largest nitrogen fertilizer complex in North America); Medicine Hat, Alberta (the largest nitrogen fertilizer complex in Canada); Port Neal, Iowa; Courtright, Ontario; Yazoo City, Mississippi; and Woodward, Oklahoma;


•	a 75.3% interest in Terra Nitrogen Company, L.P. (TNCLP), a publicly-traded limited partnership of which we are the sole general partner and the majority limited partner and which, through its subsidiary Terra Nitrogen, Limited Partnership (TNLP), operates a nitrogen fertilizer manufacturing facility in Verdigris, Oklahoma;

Table of Contents


•	an extensive system of terminals and associated transportation equipment located primarily in the midwestern United States; and


•	joint venture investments that we account for under the equity method, which consist of:


•	a 50% interest in GrowHow UK Limited (GrowHow), a nitrogen products production joint venture located in the United Kingdom and serving primarily the British agricultural and industrial markets;


•	a 50% interest in Point Lisas Nitrogen Limited (PLNL), an ammonia production joint venture located in the Republic of Trinidad and Tobago; and


•	a 50% interest in KEYTRADE AG (Keytrade), a global fertilizer trading company headquartered near Zurich, Switzerland.

Our reporting segments consist of ammonia, granular urea, UAN, other, and phosphate. These segments are differentiated by products, which are used differently by agricultural customers based on crop application, weather and other agronomic factors or by industrial customers. Our management uses gross margin to evaluate segment performance and allocate resources. Total other operating costs and expenses (consisting of selling, general and administrative expenses and other operating—net) and non-operating expenses (interest and income taxes), are centrally managed and are not included in the measurement of segment profitability reviewed by management. The ammonia, granular urea, UAN and other segments are referred to in this discussion and analysis as the "Nitrogen Product Segments."

A description of our five reporting segments is included in the discussion of the operating results by business segment later in this discussion and analysis.

Items Affecting Comparability of Results

Phosphate Business Disposition

In March 2014, we sold our phosphate mining and manufacturing business and recognized pre-tax and after-tax gains on the sale of the phosphate business of $747.1 million and $461.0 million, respectively. Under the terms of the Purchase Agreement, the accounts receivable and accounts payable pertaining to the phosphate mining and manufacturing business and certain phosphate inventory held in distribution facilities were not sold to Mosaic in the Transaction and were settled in the ordinary course. During the fourth quarter of 2014, based on the ordinary course settlement of certain transactions and certain adjustments that were made in accordance with the Purchase Agreement, we increased the recognized pre-tax and after-tax gains on the Transaction to $750.1 million and $462.8 million , respectively.

Upon selling the phosphate business, we began to supply Mosaic with ammonia produced by our PLNL joint venture. The contract to supply ammonia to Mosaic from our PLNL joint venture represents the continuation of a supply practice that previously existed between our former phosphate mining and manufacturing business and other operations of the Company. Prior to March 17, 2014, PLNL sold ammonia to us for use in the phosphate business and the cost was included in our production costs in our phosphate segment. Subsequent to the sale of the phosphate business, we now sell the PLNL-sourced ammonia to Mosaic. The revenue from these sales to Mosaic and the costs to purchase the ammonia from PLNL are now included in our ammonia segment. Our 50% share of the operating results of our PLNL joint venture continues to be included in our equity in earnings of operating affiliates in our consolidated statements of operations. Because of the significance of this continuing supply practice, in accordance with U.S. generally accepted accounting principles (GAAP), the phosphate mining and manufacturing business is not reported as discontinued operations in our consolidated statements of operations.

The phosphate mining and manufacturing business assets we sold in the Transaction include the Hardee County Phosphate Rock Mine; the Plant City Phosphate Complex; an ammonia terminal, phosphate warehouse and dock at the Port of Tampa; and the site of the former Bartow Phosphate Complex. In addition, Mosaic assumed certain obligations related to the phosphate mining and manufacturing business, including responsibility for closure, water treatment and long-term maintenance and monitoring of the phosphogypsum stacks at the Plant City and Bartow complexes. Mosaic also received the value of the phosphate mining and manufacturing business's asset retirement obligation trust and escrow funds totaling approximately $200 million. The assets and liabilities sold to Mosaic were classified as held for sale as of December 31, 2013; therefore, no depreciation was recorded in 2014 for the related property, plant and equipment.

Financial Executive Summary


•	We reported net earnings attributable to common stockholders of $230.6 million in the first quarter of 2015 compared to net earnings of $708.5 million in the first quarter of 2014 , a decrease of $477.9 million , or 67% . Our results for the first quarter of 2014 included a $747.1 million pre-tax gain ($461.0 million after tax) on the sale of the phosphate business.


•	During the first quarter of 2015 , we experienced lower net earnings compared to the first quarter of 2014 due primarily to a combination of lower gross margin from our Nitrogen Product Segments, the gain on the sale of the phosphate business in 2014, and higher other operating expenses.

◦

Our gross margin declined by $27.0 million , or 6% , to $415.8 million in the first quarter of 2015 from $442.8 million in the first quarter of 2014 . The absence of phosphate segment results in the first quarter of 2015 represented $8.5 million of the decline and the Nitrogen Product Segments accounted for the remaining $18.5 million of the decline. The Nitrogen Product Segments gross margin was impacted by the following factors:


▪	a 4% decline in volume;


▪	higher natural gas costs as a result of realized losses on natural gas derivatives that were entered into in prior periods when gas prices were higher;


▪	costs for ammonia that was sold in the first quarter of 2015 were incurred in earlier periods when natural gas costs were higher; and


▪	higher other production costs including costs related to the planned turnaround of our Verdigris nitrogen complex.

These factors were partially offset by unrealized mark-to-market gains on natural gas derivatives that were recognized in the first quarter of 2015 as compared to unrealized mark-to-market losses that were recognized in the prior year period.

◦

Other operating expenses increased by $24.0 million from income of $5.8 million in the first quarter of 2014 to expense of $18.2 million in the first quarter of 2015 . This change is due primarily to realized and unrealized losses on foreign exchange derivatives, losses on the disposal of fixed assets, and higher expansion project costs pertaining to our capacity expansion projects in Donaldsonville, Louisiana and Port Neal, Iowa, partially offset by unrealized foreign currency transaction gains. The foreign exchange derivative contracts are used to hedge our euro exposure on equipment purchases related to our capacity expansion projects.

•

Diluted net earnings per share attributable to common stockholders decreased $8.11, or 63% , to $4.79 per share in the first quarter of 2015 from $12.90 per share in the first quarter of 2014. This decrease is due primarily to the $8.39 per share gain from the sale of the phosphate business in the first quarter of 2014 partially offset by the impact of lower diluted weighted-average shares outstanding in 2015 as compared to the prior year. Diluted weighted-average shares outstanding decreased 12% between the first quarter of 2014 and the first quarter of 2015 due to our share repurchase activity.

•

Our first quarter 2015 results included $28.7 million of unrealized net mark-to-market gain s ( $18.1 million after tax) on natural gas derivatives, $9.1 million of expenses ( $5.7 million after tax) related to our capacity expansion projects in Donaldsonville, Louisiana, and Port Neal, Iowa that did not qualify for capitalization, and $23.2 million of realized and unrealized net loss es ( $14.6 million after tax) on foreign currency derivatives related to our capacity expansion projects. Net earnings attributable to common stockholders of $708.5 million for the first quarter of 2014 included a $747.1 million pre-tax gain on the sale of the phosphate business ($461.0 million after tax), $22.6 million of unrealized net mark-to-market loss es ( $14.4 million after tax) on natural gas derivatives, a $0.9 million realized and unrealized net gain ( $0.6 million after tax) on foreign currency derivatives related to our capacity expansion projects in Donaldsonville, Louisiana, and Port Neal, Iowa, and $8.1 million of expenses ( $5.1 million after tax) related to our capacity expansion projects that did not qualify for capitalization.


•	Our net sales decreased $179.0 million , or 16%, in the first quarter of 2015 compared to the first quarter of 2014 due primarily to the $145.1 million decline in net sales as a result of the sale of the phosphate business in the first quarter of 2014. Our Nitrogen Product Segments net sales decrease d $33.9 million , or 3% , due primarily to a 4% decrease in volume.

Net cash provided by operating activities during the first three months of 2015 was $530.9 million as compared to $750.0 million in the first three months of 2014 . The $219.1 million decrease in net cash provided by operating activities resulted from a combination of unfavorable working capital changes during the first three months of 2015 as compared to the same period of 2014 and lower earnings from our core operating activities. Unfavorable working capital changes during the first three months of 2015 included lower customer advances received compared to the year ago period, as we started 2015 with significantly higher advances for spring application compared to the beginning of 2014. This was partially offset by lower cash spending on inventory during the first three months of 2015 compared to the prior year quarter.

•

Net cash used in investing activities was $429.6 million in the first three months of 2015 as compared to net cash provided by investing activities of $469.0 million in the first three months of 2014 when we received proceeds of $1.4 billion from the sale of the phosphate business and subsequently deposited $505.0 million to restricted cash funds pertaining to our capacity expansion projects. During the first three months of 2015 , capital expenditures totaled $444.8 million compared to $392.4 million in the first three months of 2014. The increase in capital expenditures is primarily related to the capacity expansion projects in Donaldsonville, Louisiana and Port Neal, Iowa.


•	During the first quarter of 2015 , we purchased 0.8 million shares of our common stock at an average price of $291 per share, representing 1.7% of the prior year-end outstanding shares, at a cost of $236.6 million .

First Quarter of 2015 Compared to First Quarter of 2014

Consolidated Operating Results

Our reporting segments consist of ammonia, granular urea, UAN, other, and phosphate. The ammonia, granular urea, UAN and other segments are referred to in this discussion and analysis as the "Nitrogen Product Segments."

Our total gross margin declined by $27.0 million , or 6% , to $415.8 million in the first quarter of 2015 from $442.8 million in the same quarter of 2014 . The absence of phosphate segment results in the first quarter of 2015 represented $8.5 million of the decline and the Nitrogen Product Segments accounted for the remaining $18.5 million of the decline. The Nitrogen Product Segments gross margin was impacted by the following factors:


•	Volume, primarily UAN and ammonia, decreased by 4%, which reduced gross margin by $27.3 million.

•

Natural gas costs included in cost of sales increased in the first quarter of 2015 and reduced gross margin by $38.3 million as compared to the first quarter of 2014. These costs include the realized losses on natural gas derivatives that settled in the period as natural gas prices declined from floor prices on collars entered into in earlier periods. Additionally, certain products sold in the first quarter of 2015 were manufactured in earlier periods when natural gas prices were higher.


•	Unrealized net mark-to-market gains on natural gas derivatives increased gross margin by $51.3 million as the first quarter of 2015 included a $28.7 million gain and the first quarter of 2014 included a $22.6 million loss .


•	Other production costs, including costs related to the planned turnaround of our Verdigris nitrogen complex, increased compared to the prior year quarter.

Net earnings attributable to common stockholders of $230.6 million in the first quarter of 2015 included a $28.7 million pre-tax unrealized net mark-to-market gain ( $18.1 million after tax) on natural gas derivatives, $9.1 million of expenses ( $5.7 million after tax) related to our capacity expansion projects in Donaldsonville, Louisiana, and Port Neal, Iowa that did not qualify for capitalization, and $23.2 million of realized and unrealized net loss es ( $14.6 million after tax) on foreign currency derivatives related to our capacity expansion projects. Net earnings attributable to common stockholders of $708.5 million for the first quarter of 2014 included a $747.1 million pre-tax gain on the sale of the phosphate business ($461.0 million after tax), $22.6 million of pre-tax unrealized net mark-to-market loss es ( $14.4 million after tax), a $0.9 million ( $0.6 million after tax) realized and unrealized net gain on foreign currency derivatives, and $8.1 million of expenses ( $5.1 million after tax) related to our capacity expansion projects that did not qualify for capitalization.

Net Sales

Net sales decreased $179.0 million , or 16% , to $0.9 billion in the first quarter of 2015 compared to $1.1 billion in the first quarter of 2014 with a $33.9 million decrease attributable to the Nitrogen Product Segments and a $145.1 million decrease due to the absence of phosphate segment results in the first quarter of 2015 . Nitrogen Product Segments net sales decrease d due to a 4% decrease in volume while average selling prices were unchanged. The decrease in Nitrogen Product Segments volume was due primarily to lower UAN and ammonia volume partially offset by higher granular urea and other segment volume. Our UAN volume was lower primarily due to cautious customer buying activity associated with declining global nitrogen prices in the first quarter of 2015 and fewer attractive sales opportunities where product was available. Our ammonia volume was lower in the first quarter of 2015 as we chose to build inventory for the forthcoming spring application. These declines were partially offset by higher granular urea volume as we benefited from solid product movement into downstream storage in preparation for the spring application season and our other product volume, primarily DEF, increased along with the growing North American DEF market.

Nitrogen Product Segments average selling prices were $327 per ton in the first quarter of 2015, similar to the prior year quarter as higher ammonia selling prices in 2015 offset lower granular urea prices as China continued to export record amounts of granular urea, putting downward pressure on prices. Ammonia prices in the first quarter of 2015 were higher primarily due to a tighter North American supply position compared to the first quarter of 2014 and favorable price realization in the first quarter of 2015 from forward contracts entered into during the fall of 2014.

Cost of Sales

Cost of sales decreased $152.0 million , or 22% , from the first quarter of 2014 to the first quarter of 2015 due primarily to the sale of the phosphate business which reported cost of sales of $136.6 million in the prior year quarter. Cost of sales per ton in our Nitrogen Product Segments averaged $185 in the first quarter of 2015 , a slight increase from the $183 per ton in the same quarter of 2014 as the impact of lower purchased natural gas costs, realized derivative losses, unrealized derivative gains and changes in other manufacturing costs netted to a virtually unchanged cost per ton during the first quarter of 2015 compared to

Table of Contents

the first quarter of 2014. Purchased natural gas prices declined during the first quarter of 2015, however, a portion of our inventory that was sold in the first quarter of 2015 was manufactured in prior periods when gas prices were higher. The first quarter of 2015 included $28.7 million of pre-tax unrealized net mark-to-market gain s on natural gas derivatives compared to loss es of $22.6 million in the first quarter of 2014 .

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased $1.6 million to $40.1 million in the first quarter of 2015 from $41.7 million in the same quarter of 2014 due primarily to lower professional services for certain corporate projects.

Other Operating—Net

Other operating—net was $18.2 million of expense in the first quarter of 2015 compared to $5.8 million of income in the same quarter of 2014 . The increased expense was due primarily to realized and unrealized losses on foreign exchange derivatives, losses on the disposal of fixed assets, higher expansion project costs pertaining to our Donaldsonville, Louisiana and Port Neal, Iowa capacity expansion projects, partially offset by unrealized foreign currency transaction gains due to the strengthening U.S. dollar.

Equity in Earnings of Operating Affiliates

Equity in earnings of operating affiliates consists of our 50% share of the operating results of PLNL and our 50% interest in an ammonia storage joint venture located in Houston, Texas. Equity in earnings of operating affiliates was $9.7 million in the first quarter of 2015 compared to $15.8 million in the first quarter of 2014 . The decrease was due primarily to lower earnings from PLNL.

Interest Expense—Net

Net interest expense was $33.5 million in the first quarter of 2015 compared to $39.8 million in the first quarter of 2014 . The $6.3 million decrease was due primarily to higher amounts of capitalized interest related to our capacity expansion projects, partially offset by higher interest expense pertaining to the $1.5 billion of senior notes that were issued in March 2014. We recorded capitalized interest of $31.5 million and $12.9 million in the first quarter of 2015 and 2014, respectively.

Income Taxes

Our income tax provision for the first quarter of 2015 was $112.7 million on pre-tax income of $333.7 million , or an effective tax rate of 33.8% , compared to an income tax provision of $413.2 million on pre-tax income of $1,130.1 million , or an effective rate of 36.6% in the prior year first quarter. The decrease in the effective tax rate is due primarily to the higher effective tax rate on the gain related to the sale of our phosphate business in March 2014.

We have not recorded a tax provision on the earnings attributable to the noncontrolling interest in TNCLP (a partnership), which is not a taxable entity. For additional information on income taxes, see Note 10—Income Taxes to our unaudited interim consolidated financial statements included in Part I of this report.

Equity in Earnings of Non-Operating Affiliates—Net of Taxes

Equity in earnings of non-operating affiliates—net of taxes consists of our share of the operating results of unconsolidated joint venture interests in GrowHow and Keytrade. The $11.4 million increase in the first quarter of 2015 compared to the first quarter of 2014 was due primarily to increased earnings from GrowHow due to lower natural gas prices in the United Kingdom and increased sales volume.

Net Earnings Attributable to Noncontrolling Interest

Net earnings attributable to noncontrolling interest decreased $6.6 million in the first quarter of 2015 compared to 2014 due primarily to lower net earnings attributable to the 24.7% interest of the publicly-held common units of TNCLP.

Diluted Net Earnings Per Share Attributable to Common Stockholders

Diluted net earnings per share attributable to common stockholders decreased $8.11, or 63% to $4.79 per share in the first quarter of 2015 from $12.90 per share in the first quarter of 2014. This decrease is due primarily to the $8.39 per share gain from the sale of the phosphate business in the first quarter of 2014 partially offset by the impact of lower diluted weighted-average shares outstanding in 2015 as compared to the prior year. Diluted weighted-average shares outstanding decreased 12% between the first quarter of 2014 and the first quarter of 2015 due to our share repurchase activity.

Operating Results by Business Segment

The phosphate segment reflects the reported results of the phosphate business through March 17, 2014, plus the continuing sales of the phosphate inventory in the distribution network after March 17, 2014. The remaining phosphate inventory was sold in the second quarter of 2014; therefore, the phosphate segment does not have operating results subsequent to that quarter. The segment will continue to be included until the reporting of comparable period phosphate results ceases. We use gross margin to evaluate segment performance and allocate resources. Total other operating costs and expenses (consisting of selling, general and administrative expenses and other operating—net) and non-operating expenses (interest and income taxes), are centrally managed and are not included in the measurement of segment profitability reviewed by management.

Ammonia Segment

Our ammonia segment produces anhydrous ammonia (ammonia), which is our most concentrated nitrogen fertilizer as it contains 82% nitrogen. The results of our ammonia segment consist of sales of ammonia to external customers. In addition, ammonia is the "basic" nitrogen product that we upgrade into other nitrogen products such as granular urea and UAN. We produce ammonia at all seven of our nitrogen manufacturing complexes in North America.

First Quarter of 2015 Compared to First Quarter of 2014

Net Sales. Net sales in the ammonia segment increase d by $15.3 million , or 6% , in the first quarter of 2015 from the first quarter of 2014 due primarily to a 15% increase in average selling prices partially offset by an 8% decrease in volume. Average selling prices increased to $542 per ton in the first quarter of 2015 from $472 per ton in the first quarter of 2014 due to a combination of an overall tighter North American inventory position in the first quarter of 2015 and favorable price realization from forward contracts entered into during the fall of 2014. Prices entering 2015 were higher as a high level of global production outages towards the end of 2014 limited supply. Prices were lower entering 2014 due to higher levels of producer inventory carried over from 2013. Our volume was lower in the first quarter of 2015 primarily due to lower offseason agricultural sales as we chose to build inventory for the forthcoming spring application. The volume decrease was partially offset by increased ammonia sales to Mosaic under our contract to supply them ammonia from our PLNL joint venture that started late in the first quarter of 2014.

Cost of Sales. Cost of sales per ton in our ammonia segment averaged $316 in the first quarter of 2015 , a 23% increase from the $257 per ton in the same quarter of 2014 . The increase was due primarily to losses on realized natural gas derivatives that settled during the first quarter of 2015 and were entered into in earlier periods when gas prices were higher. Purchased natural gas prices declined during the first quarter of 2015, however, a portion of our inventory that was sold in the first quarter of 2015 was manufactured in prior periods when gas prices were higher. Higher maintenance and fixed costs associated with a planned turnaround at our Verdigris nitrogen complex also increased costs during the first quarter of 2015. Partially offsetting these costs were unrealized net mark-to-market gains on natural gas derivatives in the first quarter of 2015 compared to losses in the first quarter of 2014.

Granular Urea Segment

Our granular urea segment produces granular urea which contains 46% nitrogen. Produced from ammonia and carbon dioxide, it has the highest nitrogen content of any of our solid nitrogen fertilizers. Granular urea is produced at our Courtright, Ontario; Donaldsonville, Louisiana; and Medicine Hat, Alberta nitrogen complexes.

First Quarter of 2015 Compared to First Quarter of 2014

Net Sales. Net sales in the granular urea segment decrease d $4.0 million , or 2% , in the first quarter of 2015 from the first quarter of 2014 due primarily to an 8% decrease in average selling prices partially offset by a 7% increase in volume. Average selling prices decrease d to $344 per ton in the first quarter of 2015 compared to $374 per ton in the first quarter of 2014 primarily due to increased global supply as a result of growing Chinese exports. During the quarter, imports of granular urea into North America continued which weighed on selling prices.

Cost of Sales. Cost of sales per ton in our granular urea segment averaged $162 in the first quarter of 2015 , an 18% decrease from the $198 per ton in the same quarter of 2014 . The decrease was due primarily to lower realized natural gas costs for granular urea plus the impact of unrealized net mark-to-market gain s on natural gas derivatives in the first quarter of 2015 compared to loss es in the first quarter of 2014 .

UAN Segment

Our UAN segment produces urea ammonium nitrate solution (UAN). UAN, a liquid fertilizer product with a nitrogen content that typically ranges from 28% to 32%, is produced by combining urea and ammonium nitrate. UAN is produced at our nitrogen complexes in Courtright, Ontario; Donaldsonville, Louisiana; Port Neal, Iowa; Verdigris, Oklahoma; Woodward, Oklahoma; and Yazoo City, Mississippi.

The following table presents summary operating data for our UAN segment:

⁽¹⁾	UAN represents between 28% and 32% of nitrogen content, depending on the concentration specified by the customer. Nutrient tons represent the equivalent tons of nitrogen within the product tons.

First Quarter of 2015 Compared to First Quarter of 2014

Net Sales. Net sales in the UAN segment decrease d $44.2 million , or 11%, in the first quarter of 2015 from the first quarter of 2014 due primarily to a 9% decrease in volume and a 2% decrease in average selling prices. The decrease d volume was due to lower domestic sales partially offset by increased exports. Domestic volume was lower due to a combination of cautious customer buying activity associated with declining global nitrogen prices in the first quarter of 2015 and fewer attractive sales opportunities where product was available. Average selling prices decrease d slightly to $270 per ton in the first quarter of 2015 compared to $276 per ton in the first quarter of 2014 .

Cost of Sales. Cost of sales per ton in our UAN segment averaged $149 in the first quarter of 2015 , a 1% decrease from the $151 per ton in the first quarter of 2014 . The cost per ton was impacted by lower purchased natural gas costs, realized natural gas derivative losses, unrealized net mark-to-market gains on derivatives and changes in other manufacturing costs that netted to a virtually unchanged cost per ton during the first quarter of 2015 compared to the first quarter of 2014. The other manufacturing costs include costs associated with the planned turnaround at our Verdigris nitrogen complex.

Other Segment

Our other segment primarily includes the following products:


•	Ammonium nitrate (AN) is a granular, nitrogen-based product with a nitrogen content of primarily 34%. AN is used by industrial customers for commercial explosives and blasting systems, and can also be used as nitrogen fertilizer. AN is produced at our Yazoo City, Mississippi complex.

•

Diesel exhaust fluid (DEF) is an aqueous urea solution typically made with 32.5% high-purity urea and 67.5% deionized water. DEF is used as a consumable in selective catalytic reduction in order to lower nitrogen oxide (NOx) concentration in the diesel exhaust emissions from diesel engines. This product is produced at our Courtright, Ontario; Port Neal, Iowa; Woodward, Oklahoma; and Yazoo City, Mississippi, complexes.


•	Urea liquor is a liquid product that we sell in concentrations of 40%, 50% and 70% urea as a chemical intermediate. This product is produced at our Courtright, Ontario; Port Neal, Iowa; Woodward, Oklahoma; and Yazoo City, Mississippi complexes.

First Quarter of 2015 Compared to First Quarter of 2014

Net Sales. Net sales in our other segment decrease d $1.0 million , or 1% , in the first quarter of 2015 from the first quarter of 2014 due primarily to a 9% decrease in average selling prices partially offset by a 9% increase in volume. Average selling prices were lower primarily due to a sales mix shift to lower priced products. Overall, our other segment volume increased due to higher DEF sales into the growing North American DEF market. DEF volumes across North America are increasing in response to stricter diesel engine emission requirements.

Cost of Sales. Cost of sales per ton in our other segment averaged $163 in the first quarter of 2015 , a 7% decrease from the $176 per ton in the first quarter of 2014 , primarily due to the impact of unrealized net mark-to-market gains on natural gas derivatives in the first quarter of 2015 compared to losses in the first quarter of 2014.

Phosphate Segment

On March 17, 2014, we sold our phosphate mining and manufacturing business to Mosaic pursuant to an Asset Purchase Agreement dated as of October 28, 2013. The phosphate segment reflects the reported results of the phosphate business through March 17, 2014, plus the continuing sales of the phosphate inventory in the distribution network after March 17, 2014. The remaining phosphate inventory was sold in the second quarter of 2014; therefore, the phosphate segment does not have operating results subsequent to that quarter. The segment will continue to be included until the reporting of comparable period phosphate results ceases. The assets and liabilities sold were classified as held for sale as of December 31, 2013; therefore, no depreciation was recorded in 2014 for the related property, plant and equipment.

Liquidity and Capital Resources

Our primary uses of cash are generally for operating costs, working capital, capital expenditures, debt service, investments, taxes, share repurchases and dividends. Our working capital requirements are affected by several factors, including demand for our products, selling prices, raw material costs, freight costs and seasonal factors inherent in the business. Generally, our primary source of cash is cash from operations, which includes cash generated by customer advances. We may also from time to time access the capital markets or engage in borrowings under our credit agreement.

Cash and Cash Equivalents

We had cash and cash equivalents of $1.8 billion and $2.0 billion as of March 31, 2015 and December 31, 2014 , respectively.

Share Repurchase Program

The following table summarizes the share repurchases under the 2014 Program and the 2012 Program:



	2014 Program					2012 Program

First quarter	0.8	$	236.6	$	291
Shares repurchased as of March 31, 2015	2.2	$	609.4	$	275

As of March 31, 2015 and December 31, 2014 , the amount of shares repurchased that was accrued but unpaid was $29.6 million and $29.1 million , respectively.

As of March 31, 2015 and December 31, 2014 , we held in treasury approximately 1.7 million and 0.8 million shares of repurchased stock, respectively.

Consistent with our previous stock repurchase programs, repurchases under this program may be made from time to time in the open market, through privately-negotiated transactions, through block transactions or otherwise. The manner, timing and amount of repurchases will be determined by our management based on the evaluation of market conditions, stock price and other factors.

Capacity Expansion Projects and Restricted Cash

We are currently constructing new ammonia and urea/UAN plants at our Donaldsonville, Louisiana complex and new ammonia and urea plants at our Port Neal, Iowa complex. In combination, these new facilities will be able to produce 2.1 million tons of gross ammonia per year, upgraded products ranging from 2.0 million to 2.7 million tons of granular urea per year and up to 1.8 million tons of UAN 32% solution per year, depending on our choice of product mix.

Table of Contents

In the fourth quarter of 2014, we updated our cost estimate to complete the projects to construct new ammonia, urea and UAN plants at Donaldsonville, Louisiana and new ammonia and urea plants at Port Neal, Iowa. The update was based upon refined estimates for specific quantities of construction materials and work-hours based upon final issued-for-construction drawings from the engineering firms designing the plants.

These new plants will increase our product mix flexibility at Donaldsonville, improve our ability to serve upper-Midwest urea customers from our Port Neal location, and allow us to benefit from the cost advantages of North American natural gas. The projects continue to progress on-schedule, with anticipated start up dates of the third quarter 2015 for granular urea, fourth quarter 2015 for UAN and early 2016 for ammonia at Donaldsonville, Louisiana. Port Neal is scheduled to start up mid-2016 for ammonia and in the third quarter of 2016 for granular urea.

The aggregate cost estimate for both projects is approximately $4.2 billion, plus or minus a few percentage points. The total project cost includes engineering and design; equipment procurement; construction; associated infrastructure including natural gas connections and power supply; and product storage and handling systems.

We expect to finance expenditures for the capacity expansion projects through available cash and cash equivalents, cash generated from operations and borrowings. Total cash spent through the first quarter of 2015 on capitalized expenditures for the expansion projects was $2.1 billion , including $318.2 million during the first quarter of 2015 . In addition, $348.3 million was invested in the expansion projects and not paid as of March 31, 2015 and recognized as liabilities in the consolidated balance sheet.

We have retained engineering and procurement services from an affiliate of ThyssenKrupp Industrial Solutions (ThyssenKrupp), formerly ThyssenKrupp Uhde, for both capacity expansion projects. Under the terms of the engineering and procurement services contract, we have granted ThyssenKrupp a security interest in a restricted cash account and maintain a cash balance in that account equal to the cancellation fees for procurement services and equipment that would arise if we were to cancel the projects. The amount in the account will change over time based on procurement costs. As of March 31, 2015 , there was $63.3 million held in this account. This restricted cash is excluded from our cash and cash equivalents and reported separately on our consolidated balance sheet and statement of cash flows.

Capital Spending

We make capital expenditures to sustain our asset base, to increase our capacity, to improve plant efficiency and to comply with various environmental, health and safety requirements. Capital expenditures totaled $444.8 million in the first three months of 2015 compared to $392.4 million in the first three months of 2014 . The increase in capital expenditures is primarily the result of the $318.2 million increase in cash spent on the two capacity expansion projects in the first three months of 2015 . This increase is partially offset by reduced capital expenditures on sustaining projects compared to the previous year period.

Projected Capital Spending

We expect capital expenditures in 2015 to be approximately $2.0 billion to $2.5 billion, including $1.5 billion to $2.0 billion for the capacity expansion projects and $0.5 billion of sustaining and other capital expenditures. Planned capital expenditures are subject to change due to delays in regulatory approvals 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, acceleration or delays in the timing of the work and other unforeseen difficulties.

Debt

Credit Agreement

In the first quarter of 2015, we expanded our revolving credit facility size from $1.0 billion to $1.5 billion of borrowing by CF Industries, for general corporate purposes, and extended the maturity from May 2018 to March 2020. All obligations under the credit agreement are unsecured. Currently, CF Holdings is the only guarantor of CF Industries' obligations under the credit agreement. Certain of CF Industries' material domestic subsidiaries would be required to become guarantors under the credit agreement if such subsidiary were to guarantee our other debt or CF Industries' debt in excess of $450.0 million. As of March 31, 2015 , $1,495.1 million was available for borrowing under the credit agreement, net of $4.9 million of outstanding letters of credit, and there were no outstanding borrowings.

The credit agreement includes representations, warranties, covenants and events of default, including requirements that we maintain a minimum interest coverage ratio and not exceed a maximum total leverage ratio, as well as other customary covenants and events of default. As of March 31, 2015 , we were in compliance with all covenants under the credit agreement.

Table of Contents

Senior Notes

At both March 31, 2015 and December 31, 2014 , we had $4.6 billion of senior notes outstanding with maturities ranging from 2018 through 2044 as follows:



	Maturity Date	March 31, 2015		December 31, 2014
		(in millions)
6.875% senior notes	May 1, 2018	$	800.0	$	800.0
7.125% senior notes	May 1, 2020	800.0		800.0
3.450% senior notes	June 1, 2023	749.4		749.4
5.150% senior notes	March 15, 2034	746.2		746.2
4.950% senior notes	June 1, 2043	748.8		748.8
5.375% senior notes	March 15, 2044	748.1		748.1
		$	4,592.5	$	4,592.5

If a Change of Control occurs together with a Ratings Downgrade (as both terms are defined under the indentures governing the senior notes), CF Industries would be required to offer to repurchase each series of senior notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest. In addition, in the event that a subsidiary of ours, other than CF Industries, becomes a borrower or a guarantor under the credit agreement (or any renewal, replacement or refinancing thereof), such subsidiary would be required to become a guarantor of the senior notes, provided that such requirement will no longer apply with respect to the senior notes due in 2023, 2034, 2043 and 2044 following the repayment of the senior notes due in 2018 and 2020 or the subsidiaries of ours, other than CF Industries, otherwise becoming no longer subject to such a requirement to guarantee the senior notes due in 2018 and 2020.

Forward Sales and Customer Advances

We offer our customers the opportunity to purchase product on a forward basis at prices and on delivery dates we propose. Therefore, our reported fertilizer selling prices and margins may differ from market spot prices and margins available at the time of shipment.

Customer advances, which typically represent a portion of the contract's sales value, are received shortly after the contract is executed, with any remaining unpaid amount generally being collected by the time the product is shipped, thereby reducing or eliminating the accounts receivable related to such sales. Any cash payments received in advance from customers in connection with forward sales contracts are reflected on our consolidated balance sheets as a current liability until related orders are shipped and revenue is recognized. As of March 31, 2015 and December 31, 2014 , we had $495.2 million and $325.4 million , respectively, in customer advances on our consolidated balance sheets.

While customer advances are generally a significant source of liquidity, the level of forward sales contracts is affected by many factors including current market conditions and our customers' outlook on future market fundamentals. If the level of sales under our forward sales programs were to decrease in the future, our cash received from customer advances would likely decrease and our accounts receivable balances would likely increase. Additionally, borrowing under our credit agreement could become necessary. Due to the volatility inherent in our business and changing customer expectations, we cannot estimate the amount of future forward sales activity.

Under our forward sales programs, a customer may delay delivery of an order due to weather conditions or other factors. These delays generally subject the customer to potential charges for storage or may be grounds for termination of the contract by us. Such a delay in scheduled shipment or termination of a forward sales contract due to a customer's inability or unwillingness to perform may negatively impact our reported sales.

Derivative Financial Instruments

We use derivative financial instruments to reduce our exposure to changes in prices for natural gas that will be purchased in the future. Natural gas is the largest and most volatile component of our manufacturing cost for nitrogen-based fertilizers. We also use derivative financial instruments to reduce our exposure to changes in foreign currency exchange rates. Because we use derivative instruments, volatility in reported quarterly earnings can result from the unrealized mark-to-market adjustments in the value of the derivatives.

Derivatives expose us to counterparties and the risks associated with their ability to meet the terms of the contracts. For derivatives that are in net asset positions, we are exposed to credit loss from nonperformance by the counterparties. We control our credit risk through the use of multiple counterparties that are multinational commercial banks, other major financial institutions or large energy companies, and, in most cases, the use of master netting arrangements.

The master netting arrangements for most of our derivative instruments contain credit-risk-related contingent features such as cross default provisions and credit support requirements. In the event of certain defaults or a credit ratings downgrade, our counterparty may request early termination and net settlement of certain derivative trades or may require us to collateralize derivatives in a net liability position.

As of March 31, 2015 and December 31, 2014 , the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was $38.3 million and $47.1 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. At both March 31, 2015 and December 31, 2014 , we had no cash collateral on deposit with counterparties for derivative contracts. As of March 31, 2015 , we had open natural gas derivative contracts for 77.4 million MMBtus and the notional amount of our open foreign currency derivatives was €144.0 million .

Pension and Other Postretirement Benefits

We contributed $0.8 million to our pension plans during the three months ended March 31, 2015 . We expect to contribute approximately $18.2 million to our pension plans over the remainder of 2015 .

Cash Flows

Operating Activities

Investing Activities

Net cash used in investing activities was $429.6 million in the first three months of 2015 as compared to net cash provided by investing activities of $469.0 million in the first three months of 2014 when we received proceeds of $1.4 billion from the sale of the phosphate business and subsequently made $505.0 million in deposits to restricted cash funds. During the first three months of 2015 , capital expenditures totaled $444.8 million compared to $392.4 million in the first three months of 2014. The increase in capital expenditures is primarily related to the capacity expansion projects in Donaldsonville, Louisiana and Port Neal, Iowa.

Financing Activities

Net cash used in financing activities was $314.3 million in the first three months of 2015 compared to net cash provided by financing activities of $602.8 million in the same period of 2014 . We repurchased 0.8 million shares of our common stock in the first three months of 2015 for $236.2 million in cash. In the first three months of 2014 , we issued senior notes and received proceeds of approximately $1.5 billion, and we repurchased 3.2 million shares of our common stock for $781.8 million in cash. Dividends paid on common stock were $71.8 million and $55.2 million in the first three months of 2015 and 2014 , respectively.

Off-Balance Sheet Arrangements

We have operating leases for certain property and equipment under various noncancelable agreements, the most significant of which are rail car leases and barge tow charters for the transportation of fertilizer. The rail car leases currently have minimum terms ranging from two to ten years and the barge charter commitments currently have terms ranging from two to seven years. We also have terminal and warehouse storage agreements for our distribution system, some of which contain minimum throughput requirements. The storage agreements contain minimum terms ranging from one to three years and commonly contain automatic annual renewal provisions thereafter unless canceled by either party. See Note 23—Leases in the notes to our consolidated financial statements appearing in our 2014 Annual Report on Form 10-K filed with the SEC on February 26, 2015 for additional information concerning leases.

We do not have any other off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Critical Accounting Policies and Estimates

There were no changes to our significant accounting policies or estimates during the first three months of 2015 .

FORWARD-LOOKING STATEMENTS

From time to time, in this Quarterly Report on Form 10-Q as well as in other written reports and oral statements, we make forward-looking statements that are not statements of historical fact and may involve a number of risks and uncertainties. These statements relate to analyses and other information that are based on forecasts of future results and estimates of amounts not yet determinable.

These forward-looking statements are made based on currently available competitive, financial and economic data, our current expectations, estimates, forecasts and projections about the industries and markets in which we operate and management's beliefs and assumptions concerning future events affecting us. These statements are not guarantees of future performance and are subject to risks, uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control.

Important factors that could cause actual results to differ materially from our expectations are disclosed under "Risk Factors" in Item 1A in our 2014 Annual Report on Form 10-K, filed with the SEC on February 26, 2015. Such factors include, among others:


•	the volatility of natural gas prices in North America;

•	difficulties in securing the supply and delivery of raw materials, increases in their costs or delays or interruptions in their delivery;


•	reliance on third party providers of transportation services and equipment;


•	the significant risks and hazards involved in producing and handling our products against which we may not be fully insured;


•	risks associated with cyber security;


•	weather conditions;


•	our ability to complete our production capacity expansion projects on schedule as planned, on budget or at all;


•	risks associated with other expansions of our business, including unanticipated adverse consequences and the significant resources that could be required;


•	potential liabilities and expenditures related to environmental, health and safety laws and regulations;


•	our potential inability to obtain or maintain required permits and governmental approvals or to meet financial assurance requirements from governmental authorities;


•	future regulatory restrictions and requirements related to greenhouse gas emissions;


•	the seasonality of the fertilizer business;


•	the impact of changing market conditions on our forward sales programs;


•	risks involving derivatives and the effectiveness of our risk measurement and hedging activities;


•	our reliance on a limited number of key facilities;


•	risks associated with joint ventures;


•	acts of terrorism and regulations to combat terrorism;


•	risks associated with international operations;


•	losses on our investments in securities;


•	deterioration of global market and economic conditions; and


•	our ability to manage our indebtedness.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are exposed to the impact of changes in commodity prices, interest rates and foreign currency exchange rates.

Commodity Prices

Our net sales, cash flows and estimates of future cash flows related to fertilizer sales are sensitive to changes in fertilizer prices as well as changes in the prices of natural gas and other raw materials unless these costs have been fixed or hedged. A $1.00 per MMBtu change in the price of natural gas would change the cost to produce a ton of ammonia, granular urea and UAN (32%) by approximately $33, $22 and $14, respectively.

Natural gas is the largest and most volatile component of the manufacturing cost for nitrogen-based fertilizers. We manage the risk of changes in natural gas prices primarily through the use of derivative financial instruments covering periods of generally less than 18 months. The derivative instruments that we use are primarily natural gas options and natural gas fixed price swaps. These derivatives settle using primarily NYMEX futures price indexes, which represent the basis for fair value at any given time. The contracts are traded in months forward and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods.

As of March 31, 2015 and December 31, 2014 , we had open natural gas derivative contracts for 77.4 million MMBtus and 58.7 million MMBtus, respectively. A $1.00 per MMBtu increase in the forward curve prices of natural gas at March 31, 2015 would result in a favorable change in the fair value of these derivative positions of approximately $57 million, and a $1.00 per MMBtu decrease in the forward curve prices of natural gas would change their fair value unfavorably by approximately $56 million.

From time to time we may purchase ammonia, granular urea and UAN on the open market to augment or replace production at our facilities.

Interest Rate Fluctuations

As of March 31, 2015 , we had six series of senior notes totaling $4.6 billion outstanding with maturity dates of May 1, 2018, May 1, 2020, June 1, 2023, March 15, 2034, June 1, 2043 and March 15, 2044. The senior notes have fixed interest rates. The fair value of our senior notes outstanding as of March 31, 2015 was approximately $5.1 billion .

Borrowings under the Credit Agreement bear a current market rate of interest and we are subject to interest rate risk on such borrowings. However, there were no borrowings under the Credit Agreement as of March 31, 2015 or 2014, or during the three -month periods then ended.

Foreign Currency Exchange Rates

Since the fourth quarter of 2012, we have entered into euro/U.S. dollar derivative hedging transactions related to the euro-denominated construction costs associated with our capacity expansion projects at our Donaldsonville, Louisiana and Port Neal, Iowa facilities. As of March 31, 2015 , the notional amount of our open foreign currency forward contracts was approximately €144.0 million and the fair value was a net unrealized loss of $36.0 million . A 10% change in U.S. dollar/euro forward exchange rates would change the fair value of these positions by $15.5 million.

We are also directly exposed to changes in the value of the Canadian dollar, the British pound, and the Swiss franc. We do not maintain any exchange rate derivatives or hedges related to these currencies.

ITEM 4. CONTROLS AND PROCEDURES.

(a) Disclosure Controls and Procedures. The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company'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, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company's disclosure controls and procedures are effective in (i) ensuring that information required to be disclosed by the Company 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 Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including the Company's Chief Executive Officer and Chief 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 Company'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 March 31, 2015 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
