	1.     Background and Basis of Presentation
	We are one of the largest manufacturers and distributors of nitrogen fertilizer products in the world. Our principal customers are cooperatives and independent fertilizer distributors. Our principal nitrogen fertilizer products are ammonia, granular urea, urea ammonium nitrate solution, or UAN, and ammonium nitrate, or AN. Our other nitrogen products include urea liquor, diesel exhaust fluid, or DEF, 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 U.S. and Canada. We also export nitrogen fertilizer products from our Donaldsonville, Louisiana manufacturing facilities.
	Prior to March 17, 2014, we also manufactured and distributed phosphate fertilizers. Our principal phosphate products were diammonium phosphate, or DAP, and monoammonium phosphate, or MAP. On March 17, 2014, we completed the sale of our phosphate mining and manufacturing business, which is located in Florida, to the Mosaic Company (Mosaic) for approximately $1.4 billion in cash, subject to adjustments as provided in the agreement. The sale 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 phosphate business sale transaction and are being settled in the ordinary course.
	Upon closing the phosphate business sale 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 arrangement that historically has been maintained between our former phosphate mining and manufacturing business and other operations of the Company and its subsidiaries. Because of the significance of this continuing supply arrangement, in accordance with U.S. generally accepted accounting principles, the phosphate mining and manufacturing business is not reported as discontinued operations in our consolidated statement of operations.
	The Company's results are organized into two business segments—the nitrogen segment and the phosphate 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. It is expected that the remaining phosphate inventory in the distribution network will be sold in the second quarter of 2014, at which time the phosphate segment will cease to have reported results.
	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, 2013, in accordance with accounting principles generally accepted in the United States for interim financial reporting. In the opinion of management, these statements reflect all adjustments, consisting only of normal and recurring adjustments that are necessary for the fair representation of the information for the periods presented. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. Operating results for any period presented apply to that period only and are not necessarily indicative of results for any future period.
	These statements should be read in conjunction with our audited consolidated financial statements and related disclosures included in our 2013 Annual Report on Form 10-K filed with the SEC on February 27, 2014.
	The preparation of the unaudited interim financial statements requires management to make use of estimates and assumptions that affect the reported amount of assets and liabilities, revenue and expenses and certain financial statement disclosures. Actual results could differ from these estimates. Significant estimates in these consolidated financial statements include net realizable value of inventories, the timing and ultimate settlement costs of asset retirement obligations, environmental remediation liabilities, environmental and litigation contingencies, the cost of sales incentives, useful lives of property and identifiable intangible assets, the evaluation of 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 volatility and expected lives for stock compensation instruments 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.

	3.     Phosphate Business Disposition
	In March of 2014, we completed the sale of the Company's phosphate mining and manufacturing business (the "Transaction") to Mosaic pursuant to the terms of an Asset Purchase Agreement dated as of October 28, 2013 (the "Purchase Agreement"), among the Company, CF Industries and Mosaic for approximately $1.4 billion in cash, subject to adjustments as provided in the Purchase Agreement. We recognized a pre-tax and after-tax gain 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 are being settled in the ordinary course.
	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 arrangement that historically has been maintained between our former phosphate mining and manufacturing business and other operations of the Company and its subsidiaries. These sales to Mosaic are reported in our nitrogen segment. Because of the significance of this continuing supply arrangement, in accordance with U.S. generally accepted accounting principles, the phosphate mining and manufacturing business is not reported as discontinued operations in our consolidated statement of operations.
	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. It is expected that the remaining phosphate inventory will be sold in the second quarter of 2014, at which time the phosphate segment will cease to have reported results.
	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. The assets or liabilities sold to Mosaic had been classified as held for sale prior to closing the Transaction. As a result, no depreciation was recorded during 2014 on amounts in long-lived assets classified as held for sale.

	4.     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 fertilizers. We manage the risk of changes in 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 fixed price swaps and call options traded in the over-the-counter (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. The contracts are entered into with respect to gas to be consumed in the future and settlements are scheduled to coincide with anticipated purchases of natural gas used to manufacture nitrogen products during those future periods. We use natural gas derivatives as an economic hedge of gas price risk, but without the application of hedge accounting.
	As of March 31, 2014 and December 31, 2013, we had open natural gas derivative contracts for 57.4 million MMBtus and 76.3 million MMBtus, respectively. For the three months ended March 31, 2014, we used derivatives to cover approximately 71% of our natural gas consumption.
	Foreign Currency Exchange Rates
	In the fourth quarter of 2012, our Board of Directors authorized the expenditure of $3.8 billion 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 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 early 2015 using currency forward exchange contracts.
	At March 31, 2014, the notional amount of our open foreign currency derivatives was $607.2 million. Of this amount none was designated as hedging instruments for accounting purposes. At December 31, 2013, the Company elected to de-designate the remaining cash flow hedging instruments related to our capacity expansion projects.
	No reclassification from accumulated other comprehensive income (AOCI) to income occurred in the three months ended March 31, 2014 or during 2013, and none is expected within the next twelve months. The AOCI related to our foreign currency derivatives is expected to be reclassified into income over the depreciable lives of the fixed assets associated with the capital expansion projects.
	The effect of derivatives in our consolidated statements of operations for the three months ended March 31, 2014 and 2013 is shown in the table below:

Our derivatives are executed with several counterparties, generally under International Swaps and Derivatives Association (ISDA) agreements. The ISDA agreements are master netting arrangements commonly used for OTC derivatives that mitigate exposure to counterparty credit risk, in part, by creating contractual rights of netting and setoff, the specifics of which vary from agreement to agreement. These rights are described further below:
•
Settlement netting generally allows us and our counterparties to net, into a single net payable or receivable, ordinary settlement obligations arising between us under the ISDA agreement on the same day, in the same currency, for the same types of derivative instruments, and through the same pairing of offices.
•
Close-out netting rights are provided in the event of a default or other termination event (as defined in the ISDA agreements), including bankruptcy. Depending on the cause of early termination, the non-defaulting party may elect to accelerate and terminate all or some transactions outstanding under the ISDA agreement. The values of all terminated transactions and certain other payments under the ISDA agreement are netted, resulting in a single net close-out amount payable to or by the non-defaulting party.
•
Setoff rights are provided by certain of our ISDA agreements and generally allow a non-defaulting party to elect to setoff, against the final net close-out payment, other matured and contingent amounts payable between us and our counterparties under the ISDA agreement or otherwise. Typically, these setoff rights arise upon the early termination of all transactions outstanding under an ISDA agreement following a default or specified termination event.
Most of our ISDA agreements contain credit-risk-related contingent features with sliding-scale credit support thresholds that are dependent upon the ratings assigned to our long-term unsecured debt by certain credit rating agencies. Downgrades in our credit ratings would cause the applicable threshold levels to decrease and improvements in those ratings could cause the threshold levels to increase. If our net liability positions exceed the threshold amounts, the counterparties could require cash collateral, some other form of credit support, or daily cash settlement of unrealized losses. At March 31, 2014 and December 31, 2013, the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was $0.5 million and $0.2 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, 2014 and December 31, 2013, we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with ISDA agreements generally provide us and our counterparties the right to setoff collateral against amounts owing under the ISDA agreements upon the occurrence of a default or a specified termination event.
The following table presents amounts relevant to offsetting of our derivative assets and liabilities at March 31, 2014 and December 31, 2013.

We report the fair values of our derivative assets and liabilities on a gross basis on our consolidated balance sheets. As a result, the gross amounts recognized and net amounts presented are the same.
Our exposure to credit loss from nonperformance by counterparties was approximately $52.3 million and $74.1 million at March 31, 2014 and December 31, 2013, respectively. We do not believe the contractually allowed netting, close-out netting or set-off of amounts owed to, or due from, the counterparties to our ISDA agreements would have a material effect on our financial position.

	Our income tax provision for the three months ended March 31, 2014 was $413.2 million on pre-tax income of $1,130.1 million, or an effective tax rate of 36.6%, compared to an income tax provision of $107.4 million, or an effective tax rate of 20.0% for the three months ended March 31, 2013. Our income tax provision for the three months ended March 31, 2014 includes $286.1 million of income tax expense relating to the phosphate business sale transaction, which increased the effective tax rate by 3.4%. Our effective tax rate was higher in the three months ended March 31, 2014 due to the fact that the prior year's quarter included a favorable tax effect related to the Closing Agreement with the IRS as discussed further below.
	Our effective tax rate based on pre-tax earnings differs from our effective tax rate based on pre-tax earnings exclusive of noncontrolling interest, as our consolidated income tax provision does not include a tax provision on the earnings attributable to noncontrolling interests in TNCLP, which does not record an income tax provision.
	At the time of our Initial Public Offering (IPO) in 2005, we had accumulated a substantial amount of NOLs. Due to the uncertainty of realizing the tax benefit from the NOLs when we ceased to be a non-exempt cooperative for income tax purposes when we became a public company, a full valuation allowance was recorded against those NOLs. At that time, we entered into an agreement (NOL Agreement) with the pre-IPO owners under which they would benefit should any of the pre-IPO NOLs be realized in future years by our using the NOLs to offset post-IPO taxable income. If this were to occur, we would pay the pre-IPO owners amounts equal to the resulting federal and state income taxes actually saved. At December 31, 2012, the NOLs had a potential tax benefit of $94.3 million, which had been fully reserved by the valuation allowance. In January 2013, we and the pre-IPO owners amended the NOL Agreement to provide, among other things, that we would be entitled to retain 26.9% of any settlement realized.
	In March 2013, we entered into a Closing Agreement with the IRS to resolve the tax treatment of the pre-IPO NOLs. Pursuant to the Closing Agreement, we have agreed with the IRS that we will be entitled to a tax deduction equal to a portion of the NOLs over five years commencing with the 2012 tax year. Under the terms of the amended NOL Agreement, 73.1% of the federal and state tax savings will be payable to our pre-IPO owners. As a result of the Closing Agreement, we recorded a liability of $55.2 million to recognize the tax savings from the IRS settlement that will be payable to our pre-IPO owners under the terms of the NOL Agreement. In our consolidated statement of operations for the three months ended March 31, 2013, the expense related to this liability is included in Other non-operating—net. On our consolidated balance sheet at March 31, 2014, $10.2 million is included in accounts payable and accrued expenses for the current portion of the tax savings payable to the pre-IPO owners and $32.7 million is included in other noncurrent liabilities for the portion of the tax savings payable to the pre-IPO owners in future years.

	Investments in and advances to affiliates	$	933.5	$	926
	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 nitrogen segment.
	The combined results of operations and financial position for our operating equity method investments are summarized below:
		Three months ended
		March 31,
		2014		2013
		(in millions)
	Condensed statement of operations information:

	Long-term liabilities		25		25
	Equity		168.9		170.1
	Total liabilities and equity	$	227	$	231.6
	The total carrying value of these investments at March 31, 2014 was $377.1 million, which was $292.6 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 are being depreciated over a remaining period of approximately 20 years and 10 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 approximately $34.0 million and $38.4 million for the three months ended March 31, 2014 and 2013, respectively.
	Non-Operating Equity Method Investments
	Our non-operating equity method investments consist of: (1) a 50% ownership of KEYTRADE AG (Keytrade), a fertilizer trading company headquartered near Zurich, Switzerland; and (2) a 50% ownership 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 do not include the net earnings of these investments in earnings from operations since these operations do not 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

	Equity		402.8		380.1
	Total liabilities and equity	$	844.2	$	859.6
	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. At March 31, 2014 and December 31, 2013, 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, 2014 and 2013, we recognized interest income on advances to Keytrade of $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 at March 31, 2014 was $544.0 million, which was $342.6 million more than our share of the affiliates' book value. The excess is primarily attributable to the impact of our acquisition of Terra and reflects primarily the revaluation of property, plant and equipment, identifiable intangibles and goodwill. The increased basis for property, plant and equipment and identifiable intangibles are being depreciated over remaining periods up to 12 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.
	At March 31, 2014, the amount of our consolidated retained earnings that represents our undistributed earnings of non-operating equity method investments is $28.1 million.

	CF Holdings, as a guarantor, and CF Industries, as borrower, entered into a $500 million senior unsecured credit agreement, dated May 1, 2012 (the Credit Agreement), which provided for a revolving credit facility of up to $500 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 million to $1.0 billion and extend its maturity to May 1, 2018.
	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 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' material 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 $350 million. Currently, no such subsidiary guarantees any debt.
	At March 31, 2014, there was $995.1 million of available credit under the Credit Agreement (net of outstanding letters of credit), and there were no borrowings outstanding.

The Company received net proceeds of $1.48 billion from the issuance and sale of the senior notes due in 2034 and 2044, after deducting underwriting discounts and offering expenses. The Company intends to use the net proceeds from the offering to fund capital expenditure programs and stock repurchases and for other general corporate purposes, including working capital.
	Under the indentures and supplemental indentures governing the senior notes 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 the Company and its subsidiaries, including CF Industries, to incur liens on certain properties to secure debt. In the event of specified changes in control involving CF Holdings or CF Industries, they also require CF Industries 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 our 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.

	Litigation
	West Fertilizer Co.
	In April 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 in lawsuits filed in 2013 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. Plaintiffs allege various theories of negligence, strict liability and breach of warranty under Texas law. Although we do not own or operate the facility or directly sell our product 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. Based on the initial analysis of the pending lawsuits, we believe that we have strong legal and factual defenses to the claims and intend to defend ourselves vigorously in the pending lawsuits and any other claims brought against us in connection with the incident.
	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.
	Environmental
	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 facility) 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 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 CF Industries 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.
	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 the Company's 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 may achieve attainment with the 2008 8-hour ozone standard. A determination from EPA is expected soon 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 through 2013. Additional revisions to the ozone NAAQS may affect the longevity and long-term consequences of this determination.
	Clean Air Act Information Request
	On February 26, 2009, the Company 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. The Company has completed the submittal of all requested information. There has been no further contact from the EPA regarding this matter.
	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 we may be subject to involving this or other cleanup sites will have a material adverse effect on our business, financial condition, results of operations or cash flows.

	16.   Noncontrolling Interests
	Terra Nitrogen Company, L.P. (TNCLP)
	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 have been recorded as part of noncontrolling interest in our consolidated financial statements. The noncontrolling interest represents the noncontrolling unitholders' interest in the 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 impact available cash, as increases in the amount of cash invested in working capital items (such as accounts receivable or inventory) reduce available cash, while declines in the amount of cash invested in working capital 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 2013 and 2012, 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, 2014 and 2013, were $40.5 million and $71.3 million, respectively.
	At March 31, 2014, 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.
	Canadian Fertilizers Limited (CFL)
	CFL owns a nitrogen fertilizer complex in Medicine Hat, Alberta, Canada, which until April 30, 2013, was a variable interest entity that was consolidated in the Company's financial statements. The Medicine Hat complex is the largest nitrogen fertilizer complex in Canada, with two world-scale ammonia plants, a world-scale granular urea plant and on-site storage facilities for both ammonia and urea.
	In 2012, the Company entered into agreements to acquire the noncontrolling interests in CFL for C$0.9 billion, which included 34% of CFL's common and preferred shares owned by Viterra, the product purchase agreement between CFL and Viterra and the CFL common shares held by GROWMARK, Inc. and La Coop fédérée. In April 2013, we completed the acquisitions. Since CFL was previously a consolidated variable interest entity, the purchase price was recognized as follows: a $0.8 billion reduction in paid in capital; a $0.1 billion deferred tax asset; and the removal of the CFL noncontrolling interest. CFL is now a wholly owned subsidiary.

	Total liabilities at fair value	$	0.2	$	—	$	0.2	$	—
	Following is a summary of the valuation methodologies for assets and liabilities recorded on our consolidated balance sheets at fair value on a recurring basis:
	Cash and Cash Equivalents
	At March 31, 2014 and December 31, 2013, our cash and 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 two cash accounts for which the use of the funds are restricted. The first account 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 the engineering and procurement services contract, we are required to grant an affiliate of ThyssenKrupp Udhe 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.
	Our second account includes $460.6 million of cash proceeds that were received from the phosphate mining and manufacturing business sale and deposited into a restricted cash arrangement that will be utilized over the next six months (the "Replacement Period") to purchase assets in the capacity expansion program, which qualify for like-kind exchange treatment under the federal income tax law. We currently expect to spend approximately $304 million during the Replacement Period. Any funds not expended from the account upon expiration of the Replacement Period will be returned to the Company and available for general corporate use.
	Derivative Instruments
	The derivative instruments that we use are primarily natural gas fixed price swaps, call options and foreign currency forward contracts traded in the over-the-counter markets with either large oil and gas companies or large financial institutions. 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, LA and Port Neal, IA capital expansion projects. The natural gas derivative contracts settle using 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, unrelated third party. See Note 4—Derivative Financial Instruments, for additional information.
	Asset Retirement Obligation Funds
	Prior to March 17, 2014, we maintained investments to meet financial assurance requirements associated with certain Asset Retirement Obligations (AROs) in Florida. The fair values of these investments were based upon daily quoted prices representing the Net Asset Value (NAV) of the investments. The fair values of the ARO funds approximated their cost basis. These ARO funds were transferred to Mosaic as part of the phosphate mining and manufacturing business sale. See Note 3—Phosphate Business Disposition, for additional information.
	Financial Instruments
	The carrying amounts and estimated fair values of our financial instruments are as follows:
	March 31,				December 31,
	2014				2013
	Carrying		Fair Value		Carrying		Fair Value
	Amount				Amount
Long-term debt, including current portion	$	4,592.30	$	4,914.70	$	3,098.10	$	3,276.70
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.

	18.   Segment Disclosures
	We are organized and managed based on two business segments, which are differentiated primarily by their products, the markets they serve and the regulatory environments in which they operate. Our two business segments are the nitrogen segment and the phosphate 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. It is expected that the remaining phosphate inventory will be sold in the second quarter of 2014, at which time the phosphate segment will cease to have reported results. The Company's 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.
