NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1.   Background and Basis of Presentation

We are a leading global fertilizer and chemical company. Our 3,000 employees operate world-class manufacturing complexes in Canada, the United Kingdom and the United States. Our principal customers are cooperatives, independent fertilizer distributors, farmers and industrial users. Our principal nitrogen fertilizer products are ammonia, granular urea, urea ammonium nitrate solution (UAN) and ammonium nitrate (AN). Our other nitrogen products include diesel exhaust fluid (DEF), urea liquor, nitric acid and aqua ammonia, which are sold primarily to our industrial customers, and compound fertilizer products (NPKs), which are solid granular fertilizer products for which the nutrient content is a combination of nitrogen, phosphorus, and potassium. We serve our customers in North America through our production, storage, transportation and distribution network. We also reach a global customer base with exports from our Donaldsonville, Louisiana, plant, the world’s largest and most flexible nitrogen complex. Additionally, we move product to international destinations from our Verdigris, Oklahoma, facility, our Yazoo City, Mississippi, facility, and our Billingham and Ince facilities in the United Kingdom, and from a joint venture ammonia facility in the Republic of Trinidad and Tobago in which we own a 50 percent interest.

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.

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, 2017, in accordance with U.S. generally accepted accounting principles (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 2017 Annual Report on Form 10-K filed with the SEC on February 22, 2018. 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 defined benefit pension and other postretirement benefit plans and the assumptions used in the valuation of stock-based compensation awards granted to employees.

During the first quarter of 2018, we adopted Accounting Standards Update (ASU) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. As a result, in our consolidated statements of cash flows for the six months ended June 30, 2017, we have reclassified $1 million of withdrawals from restricted cash funds, previously classified as cash flows provided by investing activities, to be included in the reconciliation of the beginning and ending balances of cash, cash equivalents and restricted cash. See Note 2—New Accounting Standards for additional information.

During the first quarter of 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. As a result, we reclassified certain amounts in our consolidated statements of operations for the three and six months ended June 30, 2017. See Note 2—New Accounting Standards for additional information.

2.   New Accounting Standards

Recently Adopted Pronouncements

On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments. Additionally, the costs to obtain and fulfill a contract, including assets to be recognized, are to be capitalized and such capitalized costs should be disclosed. In 2016, the Financial Accounting Standards Board (FASB) issued additional ASUs that enhanced the operability of the principal versus agent guidance in ASU No. 2014-09 by clarifying that an entity should consider the nature of each good or service promised to a customer at the individual good or service level, clarified that ASU No. 2014-09 should not be applied to immaterial performance obligations, and enhanced the guidance around the treatment of shipping costs incurred to fulfill performance obligations. Our adoption of this ASU, utilizing the modified retrospective approach on contracts that were not completed as of January 1, 2018, resulted in a reduction to opening retained earnings of $1 million related to the cumulative difference between ASC Topic 605 and ASC Topic 606. See Note 3—Revenue Recognition for additional information.

On January 1, 2018, we adopted ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities, which changes the income statement impact of equity investments held by an entity. The amendments require the unrealized gains or unrealized losses of equity instruments measured at fair value to be recognized in net income. Our adoption of this ASU resulted in an increase to opening retained earnings of $1 million representing the cumulative effect of unrealized gains from equity securities from accumulated other comprehensive income (loss).

On January 1, 2018, we adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash - a consensus of the FASB Emerging Issues Task Force, which requires that the statement of cash flows include amounts described as restricted cash and restricted cash equivalents as part of cash and cash equivalents when reconciling the beginning and ending period total amounts. Upon adoption of this ASU, $1 million of withdrawals from restricted cash funds previously reflected as cash provided by investing activities for the six months ended June 30, 2017, and our restricted cash of $5 million and $4 million as of December 31, 2016 and June 30, 2017, respectively, were reclassified to be included within the reconciliation of beginning and ending cash, cash equivalents and restricted cash balances on our consolidated statement of cash flows.

On January 1, 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changed the presentation of net benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Only service cost can be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net benefit cost must be presented separately outside of operating income. Additionally, only service costs may be capitalized on the balance sheet. Our adoption of this ASU was applied retrospectively for the income statement classification requirements and prospectively for the capitalization guidance, which resulted in $1 million and $2 million of net benefit cost previously recognized in cost of sales for the three and six months ended June 30, 2017, respectively, to be reclassified to other non-operating on our consolidated statements of operations.

On January 1, 2018, we adopted ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Our adoption of this ASU had no impact on our consolidated financial statements.

Recently Issued Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in ASC Topic 840, Leases. This ASU will require lessees to recognize the rights and obligations resulting from virtually all leases (other than leases that meet the definition of a short-term lease) on their balance sheets as right-of-use assets with corresponding lease liabilities. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of income and expense recognized and expected to be recognized from existing contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and required the modified retrospective method of adoption. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides the option to adopt ASU No. 2016-02 retrospectively for each prior period presented or as of the adoption date with a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. While we are continuing to evaluate the

7

CF INDUSTRIES HOLDINGS, INC.

impact of the adoption of these ASUs on our consolidated financial statements, we currently believe the most significant change relates to the recognition of the right-of-use assets and lease liabilities on our balance sheet for operating leases for certain property and equipment, including transportation equipment utilized for the distribution of our products.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships in order to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and should be applied to existing hedging relationships as of the date of adoption. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and for interim periods therein. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

3.   Revenue Recognition

Prior to the adoption of ASC 606, under ASC 605, the basic criteria necessary for revenue recognition were: (1) evidence that a sales arrangement existed, (2) delivery of goods had occurred, (3) the seller's price to the buyer was fixed or determinable, and (4) collectability was reasonably assured. We recognized revenue when these criteria had been met, and when title and risk of loss transferred to the customer, which could be at the plant gate, a distribution facility, a supplier location or a customer destination.

We adopted ASC 606 on January 1, 2018. The revenue that we recognize, both prior to and after the adoption of ASC 606, arises from contracts we have with our customers. Our performance obligations under a contract correspond to each shipment of product that we make to our customer under the contract; as a result, each contract may have more than one performance obligation based on the number of products ordered, the quantity of product to be shipped and the mode of shipment requested by the customer. Control of our products transfers to our customers when the customer is able to direct the use of, and obtain substantially all of the benefits from, our products, which generally occurs at the later of when the customer obtains title to our product or when the customer assumes risk of loss of our product. The transfer of control generally occurs at a point in time upon loading of our product onto transportation equipment or upon delivery to the customer’s intended destination. Once this occurs, we have satisfied our performance obligation and we recognize revenue.

When we enter into a contract with a customer, we are obligated to provide the product during a mutually agreed upon time period. Depending on the terms of the contract, either we or the customer arranges delivery of the product to the customer’s intended destination. In situations where we have agreed to arrange delivery of the product to the customer’s intended destination and control of the product transfers upon loading of our product onto transportation equipment, we have elected to account for any freight income associated with the delivery of these products as freight revenue, consistent with our treatment of this income prior to the adoption of ASC 606, since this activity fulfills our obligation to transfer the product to the customer. For the three and six months ended June 30, 2018, the total amount of freight recognized as revenue was not material.

Certain of our contracts require us to supply products on a continuous basis to the customer. We recognize revenue on these contracts based on the quantity of products transferred to the customer during the period. For the three and six months ended June 30, 2018, the amount of revenue for these types of transactions was $16 million and $41 million, respectively.

From time to time, we will enter the marketplace to purchase the needed product in order to meet our customer contracts. When we purchase product to meet customer contracts, we are the principal in the transaction and recognize revenue on a gross basis. As discussed in Note 8—Equity Method Investments, we have transactions in the normal course of business with Point Lisas Nitrogen Limited (PLNL), reflecting our obligation to purchase 50% of the ammonia produced by PLNL at current market prices. During the six months ended June 30, 2018, other than products purchased from PLNL, we did not purchase any products in the marketplace in order to meet our customer contracts.

Transaction Price

We agree with our customers on the selling price of each transaction. This transaction price is generally based on the product, market conditions, including supply and demand balances, freight arrangements including where control transfers, and customer incentives. In our contracts with customers, we allocate the entire transaction price to the sale of product to the customer, which is the basis for the determination of the relative standalone selling price allocated to each performance

CF INDUSTRIES HOLDINGS, INC.

obligation. Returns of our product by our customers are permitted only when the product is not to specification, and were not material for the three and six months ended June 30, 2018. Any sales tax, value added tax, and other tax we collect concurrently with our revenue-producing activities are excluded from revenue.

We offer cash incentives to certain customers based on the volume of their purchases over a certain period. These incentives do not provide an option to the customer for additional product. Customer incentives are reported as a reduction in net sales. Accrual of these incentives involves the use of estimates, including how much product the customer will purchase and whether the customer will achieve a certain level of purchases within the incentive period. The balances of customer incentives accrued at June 30, 2018, and December 31, 2017 were not material.

If we had continued to apply legacy revenue recognition guidance for the three and six months ended June 30, 2018, our revenues, gross margin, and net income attributable to common shareholders would not have been materially different. See Note 2—New Accounting Standards for the impact of our adoption of ASU No. 2014-09.

Revenue Disaggregation

We track our revenue by product and by geography. See Note 17—Segment Disclosures for our revenue by reportable segment, which are ammonia, granular urea, UAN, AN, and Other.

The following table summarizes our revenue by product and by geography (based on destination of our shipment) for the three and six months ended June 30, 2018:

	Ammonia		Granular Urea		UAN		AN		Other		Total
	(in millions)
Three months ended June 30, 2018
North America	$	349	$	345	$	290	$	49	$	64	$	1,097

Accounts Receivable and Customer Advances

Our customers purchase our products through sales on credit or forward sales. Products sold to our customers on credit are recorded as accounts receivable when the customer obtains control of the product. Customers that purchase our products on credit are required to pay in accordance with our customary payment terms, which are generally less than 30 days. For the three and six months ended June 30, 2018, the amount of customer bad debt expense recognized was immaterial.

For forward sales, the customer prepays a portion of the value of the sales contract prior to obtaining control of the product. These prepayments, when received, are recorded as customer advances and are recognized as revenue when the customer obtains control of the product. Forward sales are customarily offered for periods of less than one year in advance of when the customer obtains control of the product.

As of June 30, 2018 and December 31, 2017, we had $21 million and $89 million, respectively, in customer advances on our consolidated balance sheets. The decrease in the balance of customer advances was primarily caused by customers taking delivery of fertilizer during the spring application season. During the six months ended June 30, 2018, all of our customer advances that were recorded as of December 31, 2017 were recognized as revenue.

CF INDUSTRIES HOLDINGS, INC.

We have certain customer contracts with performance obligations where if the customer does not take the required amount of product specified in the contract, then the customer is required to make a payment to us, which may vary based upon the terms and conditions of the applicable contract. As of June 30, 2018, excluding contracts with original durations of less than one year, and based on the minimum product tonnage to be sold and current market price estimates, our remaining performance obligations under these contracts are approximately $1.4 billion. We expect to recognize approximately 9% of these performance obligations as revenue during the remainder of 2018, approximately 36% as revenue during 2019 and 2020, approximately 30% as revenue during 2021 and 2022, and the remainder thereafter. If these customers do not fulfill their contractual obligations under such contracts, the legally enforceable minimum amount that they would pay to us under these contracts is approximately $260 million as of June 30, 2018. Other than the performance obligations described above, any performance obligations with our customers that were unfulfilled or partially filled at December 31, 2017 will be satisfied in 2018.

All of our contracts require that the period between the payment for goods and the transfer of those goods to the customer occur within normal contractual terms that do not exceed one year; therefore, we have not adjusted the transaction price of any of our contracts to recognize a significant financing component. We have also expensed any incremental costs associated with obtaining a contract that has a duration of less than one year, and there were no costs capitalized during the six months ended June 30, 2018.

8.  Equity Method Investments

We have a 50% ownership interest in PLNL, which operates an ammonia production facility in the Republic of Trinidad and Tobago. We include our share of the net earnings from this equity method investment as an element of earnings from operations because PLNL provides additional production to our operations and is integrated with our other supply chain and sales activities in the ammonia segment.

As of June 30, 2018, the total carrying value of our equity method investment in PLNL was $94 million, $50 million more than our share of PLNL’s book value. The excess is attributable to the purchase accounting impact of our acquisition of the investment in PLNL and reflects the revaluation of property, plant and equipment. The increased basis for property, plant and equipment is being amortized over a remaining period of approximately 15 years. Our equity in earnings of PLNL is different from our ownership interest in income reported by PLNL due to amortization of this basis difference.

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 $9 million and $38 million

12

CF INDUSTRIES HOLDINGS, INC.

for the three and six months ended June 30, 2018, respectively, and $24 million and $44 million for the three and six months ended June 30, 2017, respectively.

The Trinidadian tax authority (the Board of Inland Revenue) previously issued a tax assessment against PLNL related to a dispute over whether tax depreciation must be claimed during a tax holiday period that was granted to PLNL under the Trinidadian Fiscal Incentives Act. The tax holiday was granted as an incentive to construct PLNL’s ammonia plant. Based on the facts and circumstances of this matter, PLNL recorded a tax contingency accrual in the second quarter of 2017, which reduced our equity in earnings of PLNL for the three and six months ended June 30, 2017 by approximately $7 million reflecting our 50% ownership interest. In early 2018, PLNL settled this matter with the Board of Inland Revenue for the amounts accrued.

PLNL operates an ammonia plant that relies on natural gas supplied, under a Gas Sales Contract (the NGC Contract), by The National Gas Company of Trinidad and Tobago Limited (NGC). PLNL experienced past curtailments in the supply of natural gas from NGC, which reduced historical ammonia production at PLNL. The NGC Contract had an initial expiration date of September 2018 and was extended on the same terms until September 2023. Any NGC commitment to supply gas beyond 2023 will be based on new agreements. In May 2018, the NGC and PLNL reached a settlement of an arbitration proceeding regarding PLNL’s claims for damages due to the natural gas supply curtailments. The net after-tax impact of the settlement reached between NGC and PLNL that is recognized in our consolidated statements of operations for the three and six months ended June 30, 2018 was an increase in our equity in earnings of operating affiliates of approximately $19 million.

9.  Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following tables present assets and liabilities included in our consolidated balance sheets as of June 30, 2018 and December 31, 2017 that are recognized at fair value on a recurring basis, and indicate the fair value hierarchy utilized to determine such fair value:

	June 30, 2018
	Total Fair Value			Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
	(in millions)
Cash equivalents	$	672		$	672	$	—		$	—
Nonqualified employee benefit trusts	20			20		—			—

	December 31, 2017
	Total Fair Value			Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
	(in millions)
Cash equivalents	$	715		$	715	$	—		$	—
Nonqualified employee benefit trusts	19			19		—			—
Derivative assets	1			—		1			—
Derivative liabilities	(12		)	—		(12		)	—
Embedded derivative liability	(25		)	—		(25		)	—

Cash Equivalents

As of June 30, 2018 and December 31, 2017, 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.

Nonqualified Employee Benefit Trusts

We maintain trusts associated with certain nonqualified supplemental pension plans. The fair values of the trust assets are based on daily quoted prices in an active market, which represent the net asset values of the shares held in the trusts, and are included on our consolidated balance sheets in other assets. Debt securities are accounted for as available-for-sale securities. In 2018, as a result of our adoption of ASU 2016-01 on January 1, 2018, changes in the fair value of equity securities in the trust assets are recognized through earnings. See Note 2—New Accounting Standards for additional information.

Derivative Instruments

The derivative instruments that we use are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options traded in the over-the-counter (OTC) markets with multinational commercial banks, other major financial institutions or large energy companies. The natural gas derivative contracts represent anticipated natural gas needs for future periods and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods. 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 independent third party. See Note 13—Derivative Financial Instruments for additional information.

14

CF INDUSTRIES HOLDINGS, INC.

Embedded Derivative Liability

Under the terms of our strategic venture with CHS Inc. (CHS), if our credit rating as determined by two of three specified credit rating agencies is below certain levels, we are required to make a non-refundable yearly payment of $5 million to CHS. Since our credit ratings were below certain levels in 2016 and 2017, we made a payment of $5 million to CHS in each year. These payments will continue on a yearly basis until the earlier of the date that our credit rating is upgraded to or above certain levels by two of the three specified credit rating agencies or February 1, 2026. This obligation is recognized on our consolidated balance sheets as an embedded derivative. As of June 30, 2018 and December 31, 2017, the embedded derivative liability of $26 million and $25 million, respectively, is included in other current liabilities and other liabilities on our consolidated balance sheets. The inputs into the fair value measurement include the probability of future upgrades and downgrades of our credit rating based on historical credit rating movements of other public companies and the discount rates to be applied to potential annual payments based on applicable credit spreads of other public companies at different credit rating levels. Based on these inputs, our fair value measurement is classified as Level 2. For the six months ended June 30, 2018 and 2017, we recognized charges of $1 million and $3 million, respectively, related to the embedded derivative, which are included in other operating—net in our consolidated statement of operations.

See Note 14—Noncontrolling Interests for additional information regarding our strategic venture with CHS.

Financial Instruments

The carrying amount and estimated fair value of our financial instruments are as follows:

	June 30, 2018				December 31, 2017
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(in millions)
Long-term debt	$	4,695	$	4,474	$	4,692	$	4,800

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, they 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.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

We also have assets and liabilities that may be measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment, when there is allocation of purchase price in an acquisition or when a new liability is being established that requires fair value measurement. These include long-lived assets, goodwill and other intangible assets and investments in unconsolidated subsidiaries, such as equity method investments, which may be written down to fair value as a result of impairment. The fair value measurements related to each of these rely primarily on Company-specific inputs and the Company’s assumptions about the use of the assets. Since certain of the Company’s assumptions would involve inputs that are not observable, these fair values would reside within Level 3 of the fair value hierarchy.

10.   Income Taxes

For the three months ended June 30, 2018, we recorded an income tax provision of $44 million on pre-tax income of $218 million, or an effective tax rate of 20.2%, compared to an income tax provision of $5 million on pre-tax income of $29 million, or an effective tax rate of 17.7%, for the three months ended June 30, 2017.

Our effective tax rate in the first six months of 2018 is based on the U.S. federal tax rate of 21% as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, as compared to the U.S. federal tax rate of 35% that was applicable in the first six months of 2017.

Our effective tax rate is impacted by earnings attributable to noncontrolling interests in CF Industries Nitrogen, LLC (CFN) and in the second quarter of 2017 by earnings attributable to the noncontrolling interests in Terra Nitrogen Company, L.P. (TNCLP), as our consolidated income tax provision (benefit) does not include a tax provision on the earnings attributable

15

CF INDUSTRIES HOLDINGS, INC.

to the noncontrolling interests. Our effective tax rate for the three months ended June 30, 2018 and 2017, exclusive of the earnings attributable to the noncontrolling interests of $26 million and $21 million, respectively, would be 23.0% and 63.3%, respectively. See Note 14—Noncontrolling Interests for additional information.

On April 2, 2018, we purchased all of the outstanding publicly traded common units of TNCLP. Our effective tax rate in the second quarter of 2018 is impacted by a $20 million reduction to our deferred tax liability due to the change in our effective state income tax rate as a result of the implementation of legal entity structure changes related to the acquisition. See Note 14—Noncontrolling Interests for additional information.

The effective tax rate for the three months ended June 30, 2017 was also impacted by the tax contingency accrual recorded by PLNL, which reduced our earnings before income taxes by $7 million but did not change our income tax provision as the adjustment was not tax effected. See Note 8—Equity Method Investments for additional information.

During the second quarter of 2017, the valuation allowance for the net operating losses of a subsidiary of the Company that we recorded in prior periods was reduced by $12 million as the result of a statutory income tax rate change.

On July 6, 2017, the State of Illinois enacted an income tax rate increase and the impact of approximately $5 million on future tax assets and liabilities was recorded in the period of enactment.

During the third quarter of 2016, one of our Canadian subsidiaries received a Notice of Reassessment from the Canada Revenue Agency (CRA) for tax years 2006 through 2009 asserting a disallowance of certain patronage allocations. The tax assessment of CAD $174 million (or approximately $133 million), including provincial taxes but excluding any interest or penalties, is the result of an audit that was initiated by the CRA in January 2010 and involves the sole issue of whether certain patronage allocations meet the requirements for deductibility under the Income Tax Act of Canada. The reassessment has been appealed and a letter of credit in the amount of CAD $87 million (or approximately $66 million) has been posted. We believe that it is more likely than not that the patronage allocation deduction will ultimately be sustained. In the event that we do not prevail in the appeal, we should be entitled to a U.S. foreign tax credit against any incremental Canadian tax paid. This issue is currently under review by the competent authorities of Canada and the United States.

During the fourth quarter of 2017, we recorded the impact of the Tax Cuts and Jobs Act that was enacted on December 22, 2017, including a provisional amount for the impact of the transition tax liability based on amounts reasonably estimable. We have not recorded measurement period adjustments to this provisional amount in the six months ended June 30, 2018.

11.   Interest Expense

Details of interest expense are as follows:

	Three months ended   June 30,				Six months ended   June 30,

12.  Financing Agreements

Revolving Credit Agreement

We have a senior secured revolving credit agreement (the Revolving Credit Agreement) providing for a revolving credit facility of up to $750 million with a maturity of September 18, 2020. The Revolving Credit Agreement includes a letter of credit sub-limit of $125 million. Borrowings under the Revolving Credit Agreement may be used for working capital and general corporate purposes. CF Industries, the borrower under the Revolving Credit Agreement, may also designate as borrowers one or more wholly owned subsidiaries that are organized in the United States or any state thereof or the District of Columbia.

Borrowings under the Revolving Credit Agreement may be denominated in dollars, Canadian dollars, euros and British pounds, and bear interest at a per annum rate equal to an applicable eurocurrency rate or base rate plus, in either case, a specified margin, and the borrowers are required to pay an undrawn commitment fee on the undrawn portion of the commitments under the Revolving Credit Agreement and customary letter of credit fees. The specified margin and the amount of the commitment fee depend on CF Holdings’ credit rating at the time.

The guarantors under the Revolving Credit Agreement are currently comprised of CF Holdings and CF Holdings’ wholly owned subsidiaries CF Industries Enterprises, LLC (CFE), CF Industries Sales, LLC (CFS) and CF USA Holdings, LLC (CF USA).

As of June 30, 2018, we had excess borrowing capacity under the Revolving Credit Agreement of $745 million (net of outstanding letters of credit of $5 million). There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2018 or December 31, 2017, or during the six months ended June 30, 2018.

The Revolving Credit Agreement contains representations and warranties and affirmative and negative covenants, including financial covenants. As of June 30, 2018, we were in compliance with all covenants under the Revolving Credit Agreement.

Letters of Credit

In addition to the letters of credit outstanding under the Revolving Credit Agreement, as described above, we have also entered into a bilateral agreement with capacity to issue letters of credit up to $125 million (reflecting an increase of $50 million in March 2018). As of June 30, 2018, approximately $119 million of letters of credit were outstanding under this agreement.

Senior Notes

Under the indentures (including the applicable supplemental indentures) governing the senior notes due 2020, 2023, 2034, 2043 and 2044 identified in the table above (the Public Senior Notes), each series of Public Senior Notes is guaranteed by CF Holdings and CF Holdings’ wholly owned subsidiaries CFE, CFS and CF USA. CFE, CFS and CF USA became subsidiary guarantors of the Public Senior Notes as a result of their becoming guarantors under the Revolving Credit Agreement. Interest on the Public Senior Notes is payable semiannually, and the Public 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.

On November 21, 2016, CF Industries issued $500 million aggregate principal amount of 3.400% senior secured notes due 2021 (the 2021 Notes) and $750 million aggregate principal amount of 4.500% senior secured notes due 2026 (the 2026 Notes, and together with the 2021 Notes, the Senior Secured Notes). CF Holdings and the subsidiary guarantors of the Public Senior Notes are also guarantors of the Senior Secured Notes. Interest on the Senior Secured Notes is payable semiannually on December 1 and June 1 beginning on June 1, 2017, and the Senior Secured Notes are redeemable at our option, in whole at any time or in part from time to time, at specified make-whole redemption prices.

13.   Derivative Financial Instruments

We use derivative financial instruments primarily to reduce our exposure to changes in commodity prices.

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. The derivatives that we use for this purpose are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options 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 recognized in earnings. As of June 30, 2018, we had natural gas NYMEX fixed price swaps covering periods through December 2018 and natural gas basis swaps covering certain periods through March 2019.

As of June 30, 2018 and December 31, 2017, we had open natural gas derivative contracts, including natural gas fixed price swaps and natural gas basis swaps, for 19.6 million MMBtus (millions of British thermal units) and 35.9 million MMBtus, respectively. For the six months ended June 30, 2018, we used natural gas NYMEX fixed price swaps to cover approximately 9% of our natural gas consumption.

The effect of derivatives in our consolidated statements of operations is shown in the table below.

CF INDUSTRIES HOLDINGS, INC.

Most of our International Swaps and Derivatives Association (ISDA) agreements contain credit-risk-related contingent features such as cross default provisions and credit support thresholds. 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. The Revolving Credit Agreement, at any time when it is secured, provides a cross collateral feature for those of our derivatives that are with counterparties that are party to, or affiliates of parties to, the Revolving Credit Agreement so that no separate collateral would be required for those counterparties in connection with such derivatives. In the event the Revolving Credit Agreement becomes unsecured, separate collateral could be required in connection with such derivatives. As of June 30, 2018 and December 31, 2017, the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was $4 million and $12 million, respectively, which also approximates the fair value of the maximum amount of additional collateral that would need to be posted or assets needed to settle the obligations if the credit-risk-related contingent features were triggered at the reporting dates. As of June 30, 2018 and December 31, 2017, we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with certain of our 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.

The following table presents amounts relevant to offsetting of our derivative assets and liabilities as of June 30, 2018 and December 31, 2017:

	Amounts presented in consolidated balance sheets(1)			Gross amounts not offset in consolidated balance sheets
				Financial instruments			Cash collateral received (pledged)		Net amount

_______________________________________________________________________________

⁽¹⁾  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 in the table above are the same.

We do not believe the contractually allowed netting, close-out netting or setoff of amounts owed to, or due from, the counterparties to our ISDA agreements would have a material effect on our financial position.

CF Industries Nitrogen, LLC (CFN)

We have a strategic venture with CHS under which they own an equity interest in CFN, a subsidiary of CF Holdings, which represents approximately 11% of the membership interest of CFN. We own the remaining membership interest. Under the terms of CFN’s limited liability company agreement, each member’s interest will reflect, over time, the impact of the profitability of CFN and any member contributions made to, and distributions received from, CFN. For financial reporting purposes, the assets, liabilities and earnings of the strategic venture are consolidated into our financial statements. CHS’ interest in the strategic venture is recorded in noncontrolling interests in our consolidated financial statements. CHS also receives deliveries pursuant to a supply agreement under which CHS has the right to purchase annually from CFN up to approximately 1.1 million tons of granular urea and 580,000 tons of UAN at market prices. As a result of its equity interest in CFN, CHS is entitled to semi-annual cash distributions from CFN. We are also entitled to semi-annual cash distributions from CFN. The amounts of distributions from CFN to us and CHS are based generally on the profitability of CFN and determined based on the volume of granular urea and UAN sold by CFN to us and CHS pursuant to supply agreements, less a formula driven amount based primarily on the cost of natural gas used to produce the granular urea and UAN, and adjusted for the allocation of items such as operational efficiencies and overhead amounts. Additionally, under the terms of the strategic venture, we recognized an embedded derivative related to our credit rating. See Note 9—Fair Value Measurements for additional information.

In the third quarter of 2018, the CFN Board of Managers approved semi-annual distribution payments for the distribution period ended June 30, 2018 in accordance with the Second Amended and Restated Limited Liability Company Agreement of CFN, as amended. On July 31, 2018, CFN distributed $79 million to CHS for the distribution period ended June 30, 2018.

Terra Nitrogen Company, L.P. (TNCLP)

On February 7, 2018, we announced that, in accordance with the terms of TNCLP’s First Amended and Restated Agreement of Limited Partnership (as amended by Amendment No. 1 to the First Amended and Restated Agreement of Limited Partnership, the TNCLP Agreement of Limited Partnership), Terra Nitrogen GP Inc. (TNGP), the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP (the Public Units). TNGP completed its purchase of the Public Units on April 2, 2018 (the Purchase) for an aggregate cash purchase price of $388 million, which was recognized as a reduction in paid-in capital of $62 million; a deferred tax liability of $5 million; and the removal of the TNCLP noncontrolling interests, as shown in the table above. Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP.

20

CF INDUSTRIES HOLDINGS, INC.

Prior to April 2, 2018, TNCLP was a master limited partnership that owned a nitrogen fertilizer manufacturing facility in Verdigris, Oklahoma. We owned approximately 75.3% of TNCLP through general and limited partnership interests and outside investors owned the remaining approximately 24.7% of the limited partnership. For financial reporting purposes, the assets, liabilities and earnings of the partnership were consolidated into our financial statements. The outside investors’ limited partnership interests in the partnership were recorded in noncontrolling interests in our consolidated financial statements. The noncontrolling interest represents the noncontrolling unitholders’ interest (prior to the Purchase) in the earnings and equity of TNCLP. Affiliates of CF Industries were 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.

Prior to April 2, 2018, TNCLP made cash distributions to the general and limited partners based on formulas defined within the TNCLP Agreement of Limited Partnership. Cash available for distribution (Available Cash) was defined in the TNCLP Agreement of Limited Partnership 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 determined in its reasonable discretion to be necessary or appropriate. Changes in working capital affected Available Cash, as increases in the amount of cash invested in working capital items (such as increases in receivables or inventory and decreases in accounts payable) reduced Available Cash, while declines in the amount of cash invested in working capital items increased Available Cash. Cash distributions to the limited partners and general partner varied depending on the extent to which the cumulative distributions exceeded certain target threshold levels set forth in the TNCLP Agreement of Limited Partnership.

In both the first and second quarters of 2017, the minimum quarterly distributions under the TNCLP Agreement of Limited Partnership were satisfied, which entitled TNGP to receive incentive distributions on its general partner interests (in addition to minimum quarterly distributions). TNGP assigned its right to receive such incentive distributions to an affiliate of TNGP that was also an indirect wholly owned subsidiary of CF Holdings. The earnings attributed to our general partner interest in excess of the threshold levels for the six months ended June 30, 2017 was $14 million.

16.  Contingencies

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. Various subsidiaries of CF Industries Holdings, Inc. (the CF Entities) have been named as defendants along with other companies in lawsuits filed in 2013, 2014 and 2015 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 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, and breach of warranty under Texas law. Although we do not own or operate the facility or directly sell our products to West Fertilizer Co., products that the CF Entities 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.

The Court granted in part and denied in part the CF Entities’ Motions for Summary Judgment in August 2015. Over two hundred cases have been resolved pursuant to confidential settlements that have been or we expect will be fully funded by insurance. The remaining cases are in various stages of discovery and pre-trial proceedings. There is no trial date currently set; however, we anticipate that the Court will schedule a trial sometime in the beginning of 2019. We believe we have strong legal and factual defenses and intend to continue defending the CF Entities vigorously in the pending lawsuits. The Company cannot provide a range of reasonably possible loss due to the lack of damages discovery for many of the remaining claims and the uncertain nature of this litigation, including uncertainties around the potential allocation of responsibility by a jury to other defendants or responsible third parties. The recognition of a potential loss in the future in the West Fertilizer Co. litigation could negatively affect our results in the period of recognition. However, based upon currently available information, including available insurance coverage, we do not believe that this litigation will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

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

Louisiana Environmental Matters

Clean Air Act—Ozone Attainment Designation

Our Donaldsonville nitrogen complex is located in a five-parish region near Baton Rouge, Louisiana. On December 15, 2016, the EPA redesignated the Baton Rouge Nonattainment Area as “attainment” with respect to the 2008 8-hour ozone national ambient air quality standard (NAAQS). However, based on 2013-2015 air quality monitoring data, the State of Louisiana recommended that the EPA designate the Baton Rouge area as “non-attainment” pursuant to the updated 2015 8-hour ozone standard. On December 20, 2017, the EPA notified the state of Louisiana that it intends to designate the Baton Rouge area as non-attainment for the 2015 ozone standard. On January 5, 2018, the EPA published notice of a public comment period with respect to the proposed attainment/non-attainment designations of certain air quality regions, including the Baton Rouge area. The EPA subsequently determined, based on certified air emissions data for calendar year 2017, that the air quality monitors for the Baton Rouge area are attaining the 2015 standard. As a result, on April 30, 2018, the EPA Administrator signed a notice designating the Baton Rouge area as “attainment/unclassifiable” with respect to the 2015 ozone standard. Designation of the Baton Rouge area as nonattainment with respect to the 2015 ozone standard could have resulted in more stringent air pollution emissions limits for our existing operation and would have subjected our facilities to more stringent requirements to obtain approvals for plant expansions, or made it more difficult to obtain such approvals.

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. In 2015, we and several other parties received a notice that the U.S. Department of the Interior and other trustees intend to undertake a natural resource damage assessment for 17 former phosphate mines in southeast Idaho, one of which is the former Georgetown Canyon mine. We are not able to estimate at this time our potential liability, if any, with respect to the cleanup of the site or a possible claim for natural resource damages. However, based on currently available information, we do not expect the remedial or financial obligations to which we may be subject involving this or other cleanup sites will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

17.  Segment Disclosures

Our reportable segments consist of ammonia, granular urea, UAN, AN and Other. These segments are differentiated by products. 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 and six months ended June 30, 2018 and 2017 are presented in the tables below.

18.   Condensed Consolidating Financial Statements

The following condensed consolidating financial information is 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 (i) the senior notes due 2020, 2023, 2034, 2043 and 2044 (described in Note 12—Financing Agreements and referred to in this report as the Public Senior Notes) issued by CF Industries, Inc. (CF Industries), a 100% owned subsidiary of CF Industries Holdings, Inc. (Parent), and guarantees of the Public Senior Notes by Parent and by CFE, CFS and CF USA (the Subsidiary Guarantors), which are 100% owned subsidiaries of Parent, and (ii) debt securities of CF Industries (Other Debt Securities), and guarantees thereof by Parent and the Subsidiary Guarantors, that may be offered and sold from time to time under registration statements that may be filed by Parent, CF Industries and the Subsidiary Guarantors with the SEC.

In the event that a subsidiary of Parent, other than CF Industries, becomes a borrower or a guarantor under the Revolving Credit Agreement (or any renewal, replacement or refinancing thereof), such subsidiary would be required to become a guarantor of the Public Senior Notes, provided that such requirement will no longer apply with respect to the Public Senior Notes due 2023, 2034, 2043 and 2044 following the repayment of the Public Senior Notes due 2020 or the subsidiaries of Parent, other than CF Industries, otherwise becoming no longer subject to such a requirement to guarantee the Public Senior Notes due 2020. The Subsidiary Guarantors became guarantors of the Public Senior Notes as a result of this requirement.

All of the guarantees of the Public Senior Notes are, and we have assumed for purposes of this presentation of condensed consolidating financial information that the guarantees of any Other Debt Securities would be, full and unconditional (as such term is defined in SEC Regulation S-X Rule 3-10(h)) and joint and several. The guarantee of a Subsidiary Guarantor will be automatically released with respect to a series of the Public Senior Notes (1) upon the release, discharge or termination of such Subsidiary Guarantor’s guarantee of the Revolving Credit Agreement (or any renewal, replacement or refinancing thereof), (2) upon legal defeasance with respect to the Public Senior Notes of such series or satisfaction and discharge of the indenture with respect to such series of Public Senior Notes or (3) in the case of the Public Senior Notes due 2023, 2034, 2043 and 2044, upon the discharge, termination or release of, or the release of such Subsidiary Guarantor from its obligations under, such Subsidiary Guarantor’s guarantee of the Public Senior Notes due 2020, including, without limitation, any such discharge, termination or release as a result of retirement, discharge or legal or covenant defeasance of, or satisfaction and discharge of the supplemental indenture governing, the Public Senior Notes due 2020.

For purposes of the presentation of condensed consolidating financial information, the subsidiaries of Parent other than CF Industries and the Subsidiary Guarantors are referred to as the Non-Guarantors.

Presented below are condensed consolidating statements of operations for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors for the three and six months ended June 30, 2018 and 2017, condensed consolidating statements of cash flows for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors for the six months ended June 30, 2018 and 2017, and condensed consolidating balance sheets for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors as of June 30, 2018 and December 31, 2017. The condensed consolidating financial information presented below is not necessarily indicative of the financial position, results of operations, comprehensive income or cash flows of Parent, CF Industries, the Subsidiary Guarantors or the Non-Guarantors 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. As of June 30, 2018, two of our consolidated entities have made elections to be taxed as partnerships for U.S. federal income tax purposes and are included in the non-guarantor column. Due to the partnership tax treatment, these subsidiaries do not record taxes on their financial statements. The tax provision pertaining to the income of these partnerships, plus applicable deferred tax balances are reflected on the financial statements of the parent company owner that is included in the subsidiary guarantors column in the following financial information. Liabilities related to benefit plan obligations are reflected on the legal entity that funds the obligation, while the benefit plan expense is included on the legal entity to which the employee provides services.

Our principal customers are cooperatives, independent fertilizer distributors, farmers and industrial users. Our principal nitrogen fertilizer products are ammonia, granular urea, urea ammonium nitrate solution (UAN) and ammonium nitrate (AN). Our other nitrogen products include diesel exhaust fluid (DEF), urea liquor, nitric acid and aqua ammonia, which are sold primarily to our industrial customers, and compound fertilizer products (NPKs), which are solid granular fertilizer products for which the nutrient content is a combination of nitrogen, phosphorus, and potassium. We serve our customers in North America through our production, storage, transportation and distribution network. We also reach a global customer base with exports from our Donaldsonville, Louisiana, plant, the world’s largest and most flexible nitrogen complex. Additionally, we move product to international destinations from our Verdigris, Oklahoma, facility, our Yazoo City, Mississippi, facility, and our Billingham and Ince facilities in the United Kingdom, and from a joint venture ammonia facility in the Republic of Trinidad and Tobago in which we own a 50 percent interest.

Our principal assets as of June 30, 2018 include:

• five U.S. nitrogen fertilizer manufacturing facilities located in Donaldsonville, Louisiana (the largest nitrogen fertilizer complex in the world); Port Neal, Iowa; Yazoo City, Mississippi; Verdigris, Oklahoma; and Woodward, Oklahoma. These facilities are owned by CF Industries Nitrogen, LLC (CFN), of which we own approximately 89% and CHS Inc. (CHS) owns the remainder. See Note 14—Noncontrolling Interests for additional information on our strategic venture with CHS;

• two Canadian nitrogen fertilizer manufacturing facilities located in Medicine Hat, Alberta (the largest nitrogen fertilizer complex in Canada) and Courtright, Ontario;

• two United Kingdom nitrogen manufacturing complexes located in Billingham and Ince;

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

35

CF INDUSTRIES HOLDINGS, INC.

• a 50% interest in Point Lisas Nitrogen Limited (PLNL), an ammonia production joint venture located in the Republic of Trinidad and Tobago that we account for under the equity method.

Our nitrogen fertilizer manufacturing facility in Verdigris, Oklahoma, is operated by Terra Nitrogen, Limited Partnership (TNLP). Prior to April 2, 2018, TNLP was a subsidiary of Terra Nitrogen Company, L.P. (TNCLP), which was a publicly traded limited partnership of which we were the sole general partner and the majority limited partner, and in which we owned an approximate 75.3% interest.

On February 7, 2018, we announced that, in accordance with the terms of TNCLP’s First Amended and Restated Agreement of Limited Partnership (as amended by Amendment No. 1 to the First Amended and Restated Agreement of Limited Partnership, the TNCLP Agreement of Limited Partnership), Terra Nitrogen GP Inc. (TNGP), the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP (the Public Units). TNGP completed its purchase of the Public Units on April 2, 2018 (the Purchase) for an aggregate cash purchase price of $388 million. We funded the Purchase with cash on hand. Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP.

Items Affecting Comparability of Results

Sales Volume

Unfavorable weather conditions impacted sales volume in the first quarter of 2018. Drought conditions in the Southern Plains along with wet and cold temperatures throughout much of the Midwestern United States and the United Kingdom delayed the spring application season. This delay in the spring application season resulted in high inventory levels both entering and through much of the second quarter as volume typically shipped in the first quarter was instead shipped in the second quarter of 2018.

Sales volume for our products for the three months ended June 30, 2018 was 5.5 million product tons compared to 5.0 million product tons for the three months ended June 30, 2017, an increase of 10% resulting in an increase in net sales and gross margin of approximately $98 million and $37 million, respectively. Sales volume for our products for the six months ended June 30, 2018 was relatively unchanged compared to the six months ended June 30, 2017.

Selling Prices

The U.S. Gulf is a major global fertilizer pricing point due to the volume of nitrogen fertilizer that trades there. Through most of 2016, nitrogen pricing at the U.S. Gulf declined, often trading below parity with other international pricing points due to the combination of new global nitrogen production capacity that came on line in 2016, continued imports from various exporting regions and decreased North American buyer interest as a result of the greater global nitrogen supply availability. Seasonal decreases in agricultural demand combined with delayed customer purchasing activity resulted in multi-year lows in nitrogen fertilizer selling prices in the second half of 2016. In 2017, the significant price fluctuations we experienced continued and were symptoms of a market in transition as new production capacity came on line and global trade flows began to adjust.

During the first half of 2018, the nitrogen supply and demand balance tightened due to higher global nitrogen input costs for energy, feedstock and freight. This caused the idling of certain plants and significant reductions in nitrogen production operating rates primarily in high cost production regions, and especially in China, which was further impacted by enforcement of environmental regulations.

The average selling price for our products for the three months ended June 30, 2018 was $235 per ton compared to $223 per ton for the three months ended June 30, 2017, an increase of 5% resulting in an increase in both net sales and gross margin of approximately $78 million. The average selling price for our products for the six months ended June 30, 2018 was $229 per ton compared to $221 per ton for the six months ended June 30, 2017, an increase of 4% resulting in an increase in both net sales and gross margin of approximately $127 million.

Other Items Affecting Comparability

In addition to the impact of market conditions on nitrogen fertilizer selling prices and sales volume, certain significant items impacted our financial results during the three and six months ended June 30, 2018 and 2017. The following table and related discussion outline these significant items and how they impacted the comparability of our financial results during these periods. During the three months ended June 30, 2018 and 2017, we reported net earnings attributable to common stockholders of $148 million and $3 million, respectively. During the six months ended June 30, 2018 and 2017, we reported net earnings (loss) attributable to common stockholders of $211 million and $(20) million, respectively.

The following describes the significant items, identified in the table above, that impacted the comparability of our financial results for the three and six months ended June 30, 2018 and 2017. Descriptions of items below that refer to amounts in the table above refer to the pre-tax amounts.

Unrealized net mark-to-market (gain) loss on natural gas derivatives

Natural gas is typically the largest and most volatile single component of the manufacturing cost for nitrogen-based products. We manage the risk of changes in natural gas prices through the use of derivative financial instruments. The derivatives that we use for this purpose are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options. We use natural gas derivatives as an economic hedge of natural gas price risk, but without the application of hedge accounting. This can result in volatility in reported earnings due to the unrealized mark-to-market adjustments that occur from changes in the value of the derivatives, which is reflected in cost of sales in our consolidated statements of operations. In the three months ended June 30, 2018 and 2017, we recognized unrealized net mark-to-market (gain) loss of $(5) million and $18 million, respectively. In the six months ended June 30, 2018 and 2017, we recognized unrealized net mark-to-market (gain) loss of $(8) million and $71 million, respectively.

Loss (gain) on foreign currency transactions, including intercompany loans

In the three and six months ended June 30, 2018, we recognized a loss (gain) of $2 million and $(3) million, respectively, from the impact of changes in foreign currency exchange rates on primarily British pound and Canadian dollar denominated intercompany loans that were not permanently invested.

Acquisition of the TNCLP public units

In the six months ended June 30, 2018, we incurred $2 million of costs for various legal services associated with the acquisition of the publicly traded common units of TNCLP. These costs are reflected in selling, general and administrative expenses in our consolidated statements of operations.

Beginning in the second quarter of 2018, as a result of the April 2, 2018 acquisition of the TNCLP public units, there are no longer earnings attributable to noncontrolling interests in TNCLP. In the six months ended June 30, 2018, earnings attributable to noncontrolling interests in TNCLP was $8 million. In the three and six months ended June 30, 2017, earnings attributable to noncontrolling interests in TNCLP were $6 million and $12 million, respectively.

PLNL settlement income

PLNL operates an ammonia plant that relies on natural gas supplied, under a Gas Sales Contract (the NGC Contract), by The National Gas Company of Trinidad and Tobago Limited (NGC). PLNL experienced past curtailments in the supply of

37

CF INDUSTRIES HOLDINGS, INC.

natural gas, which reduced historical ammonia production at PLNL. The NGC Contract had an initial expiration date of September 2018 and was extended on the same terms until September 2023. Any NGC commitment to supply gas beyond 2023 will be based on new agreements. In May 2018, the NGC and PLNL reached a settlement of an arbitration proceeding regarding PLNL’s claims for damages due to the natural gas supply curtailments. The net after-tax impact of the settlement reached between NGC and PLNL that is recognized in our consolidated statements of operations for the three and six months ended June 30, 2018 was an increase in our equity in earnings of operating affiliates of approximately $19 million.

Equity method investment tax contingency accrual

The Trinidadian tax authority (the Board of Inland Revenue) previously issued a tax assessment against our equity method investment in the Republic of Trinidad and Tobago, PLNL, related to a dispute over whether tax depreciation must be claimed during a tax holiday period that was granted to PLNL under the Trinidadian Fiscal Incentives Act. The tax holiday was granted as an incentive to construct PLNL’s ammonia plant. PLNL was appealing the assessment. Based on the facts and circumstances of this matter, PLNL recorded a tax contingency accrual in the second quarter of 2017, which reduced our equity in earnings of PLNL for both the three and six months ended June 30, 2017 by approximately $7 million reflecting our 50% ownership interest. The amount recognized reflected our 50% ownership interest. In early 2018, PLNL settled this matter with the Board of Inland Revenue for the amounts accrued.

Financial Executive Summary

We reported net earnings attributable to common stockholders of $148 million for the three months ended June 30, 2018 compared to net earnings of $3 million for the three months ended June 30, 2017. Diluted net earnings per share attributable to common stockholders was $0.63 in the second quarter of 2018 compared to $0.01 in the second quarter of 2017. 

During the second quarter of 2018, net earnings attributable to common stockholders was higher compared to the second quarter of 2017 due primarily to an increase in gross margin driven primarily by higher average selling prices for all nitrogen products resulting from the impact of a tighter global nitrogen supply and demand balance, higher sales volumes, lower realized natural gas costs and higher unrealized net mark-to-market gains on natural gas derivatives.

In addition, net interest expense decreased to $59 million in the three months ended June 30, 2018 from $78 million in the three months ended June 30, 2017, due to our redemption in December 2017 of all of the $800 million outstanding principal amount of the 6.875% senior notes due May 2018 and our purchase in December 2017 of approximately $300 million of the $800 million outstanding aggregate principal amount of the 7.125% senior notes due 2020.

Our total gross margin increased by $139 million to $312 million in the second quarter of 2018 from $173 million in the second quarter of 2017. The increase in gross margin was due primarily to:

• an increase in average selling prices of 5%, which increased gross margin by $78 million, primarily driven by an increase in average selling prices for granular urea and UAN of 18% and 6%, respectively,

• an increase in sales volume of 10%, which increased gross margin by $37 million, primarily driven by an increase in sales volume in the UAN, Granular Urea and Other segments of 12%, 17% and 24%, respectively,

• a decrease in physical natural gas costs in the second quarter of 2018, partially offset by the impact of natural gas derivatives that settled in the period, which increased gross margin by $35 million as compared to the second quarter of 2017,

• the impact of a $5 million unrealized net mark-to-market gain in the second quarter of 2018 compared to a $18 millionloss in the second quarter of 2017, which increased gross margin by $23 million,

• partially offset by higher costs in the second quarter of 2018 due to plant turnarounds and disruptions.

Second Quarter of 2018 Compared to Second Quarter of 2017

Net Sales

Our total net sales increased$176 million, or 16%, to $1,300 million in the second quarter of 2018 compared to $1,124 million in the second quarter of 2017 due to a 10%increase in sales volume, which increased net sales by $98 million and a 5%increase in average selling prices, which increased net sales by $78 million.

Our 10% sales volume increase was driven by the delay in the spring application season due to cold and wet conditions in the first quarter of 2018. This delay resulted in high inventory levels both entering and through much of the second quarter of 2018 as certain volume typically shipped in the first quarter was instead shipped in the second quarter of 2018.

Average selling prices were $235 per ton in the second quarter of 2018 compared to $223 per ton in the second quarter of 2017 due to higher selling prices across all segments in 2018, driven by the impact of a tighter global nitrogen supply and demand balance.

Cost of Sales

Our total cost of sales increased$37 million, or 4%, from the second quarter of 2017 to the second quarter of 2018. The increase in our cost of sales was primarily due to higher sales volume and higher costs related to plant turnarounds and disruptions during the second quarter of 2018, partially offset by the impact of lower natural gas costs. Cost of sales per ton averaged $178 in the second quarter of 2018, a 6%decrease from $189 per ton in the same quarter of 2017. The second quarter of 2018 included a $5 million unrealized net mark-to-market gain compared to a $18 million unrealized net mark-to-market loss in the second quarter of 2017. Additionally, realized natural gas costs, including the impact of realized derivatives, decreased 13% from $3.39 per MMBtu in 2017 to $2.95 in 2018.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $4 million to $53 million in the second quarter of 2018 as compared to $49 million in the comparable period of 2017, due primarily to certain corporate initiatives and higher employee costs.

Other Operating—Net

Other operating—net was $3 million of expense in the second quarter of 2018 compared to $10 million of expense in the comparable period of 2017. The expense in the second quarter of 2018 was due to the combination of unrealized foreign currency losses pertaining to British pound denominated intercompany loans that have not been permanently invested and an unrealized loss on an embedded derivative liability related to our strategic venture with CHS.

Equity in Earnings (Loss) of Operating Affiliates

Equity in earnings of operating affiliates was $18 million in the second quarter of 2018 compared to a loss of $6 million in the second quarter of 2017. Earnings in the second quarter of 2018 includes approximately $19 million related to the net after-tax impact of a settlement reached between NGC and PLNL of an arbitration proceeding regarding PLNL’s claims for damages due to historical natural gas supply curtailments. See above under “Items Affecting Comparability of Results—PLNL settlement income” for additional information.

During the second quarter of 2017, PLNL recorded a tax contingency accrual related to a tax assessment against PLNL, which reduced our equity in earnings of PLNL for the six months ended June 30, 2017 by approximately $7 million reflecting our 50% ownership interest. See above under “Items Affecting Comparability of Results—Equity method investment tax contingency accrual” for additional information.

Interest Expense—Net

Net interest expense was $59 million in the second quarter of 2018 compared to $78 million in the second quarter of 2017. The $19 milliondecrease is due primarily to our redemption in December 2017 of all of the $800 million outstanding principal amount of the 6.875% senior notes due May 2018 (the 2018 Notes) and our December 2017 purchase of approximately $300 million of the $800 million outstanding aggregate principal amount of the 7.125% senior notes due 2020 (the 2020 Notes).

CF INDUSTRIES HOLDINGS, INC.

Income Taxes

For the three months ended June 30, 2018, we recorded an income tax provision of $44 million on pre-tax income of $218 million, or an effective tax rate of 20.2%, compared to an income tax provision of $5 million on pre-tax income of $29 million, or an effective tax rate of 17.7%, for the three months ended June 30, 2017. Our effective tax rate in the second quarter of 2018 is based on the U.S. federal tax rate of 21% as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, as compared to the U.S. federal tax rate of 35% that was applicable in the second quarter of 2017.

Our effective tax rate in both periods is impacted by earnings attributable to the noncontrolling interests in CFN and in the second quarter of 2017 by earnings attributable to the noncontrolling interests in TNCLP, as our consolidated income tax provision (benefit) does not include a tax provision on the earnings attributable to the noncontrolling interests. Our effective tax rate for the three months ended June 30, 2018 and 2017, exclusive of the earnings attributable to the noncontrolling interests of $26 million and $21 million, respectively, would be 23.0% and 63.3%, respectively.

On April 2, 2018, we acquired the TNCLP Public Units. Our effective tax rate in the second quarter of 2018 is impacted by a $20 million reduction to our deferred tax liability as a result of the change in our effective state income tax rate as a result of the implementation of legal entity structure changes related to the acquisition.

The effective tax rate for the three months ended June 30, 2017 was also impacted by the tax contingency accrual of $7 million recorded by PLNL, which reduced our earnings before income taxes but did not change our income tax provision as the adjustment was not tax effected.

See Note 8—Equity Method Investments, Note 10—Income Taxes and Note 14—Noncontrolling Interests for additional information.

Net Earnings Attributable to Noncontrolling Interests

Net earnings attributable to noncontrolling interests increased$5 million in the second quarter of 2018 compared to the second quarter of 2017 due to higher earnings from CFN driven by higher average selling prices due to the impact of a tighter global nitrogen supply and demand balance and lower natural gas prices, partially offset by the reduction in noncontrolling interests due to the April 2, 2018 purchase of the noncontrolling interests in TNCLP.

Diluted Net Earnings Per Share Attributable to Common Stockholders

Diluted net earnings per share attributable to common stockholders increased $0.62 to $0.63 per share in the second quarter of 2018 from $0.01 per share in the second quarter of 2017. This increase is due to higher gross margin primarily driven by higher selling prices due to the impact of a tighter global nitrogen supply and demand balance and higher sales volume due to the impact of the delay in the spring application season as volume typically shipped in the first quarter was instead shipped in the second quarter. The increase is also due to the impact of lower realized natural gas costs, including the impact of realized derivatives, and higher unrealized net mark-to-market gains on natural gas derivatives.

Six Months Ended June 30, 2018 Compared to Six Months Ended June 30, 2017

Net Sales

Our total net sales increased$96 million, or 4%, to $2,257 million in the first six months of 2018 compared to $2,161 million in the first six months of 2017 due to a 4%increase in average selling prices, which increased net sales by $127 million, and a change in product mix, which decreased net sales by $31 million.

Average selling prices were $229 per ton in the first six months of 2018, or 4% higher, as compared to $221 per ton in the first six months of 2017 due to higher selling prices across all segments. During the first half of 2018, the nitrogen supply and demand balance tightened due to higher global nitrogen input costs for energy, feedstock and freight. This caused the idling of certain plants and significant reductions in nitrogen production operating rates primarily in high cost production regions, and especially in China, which was further impacted by the enforcement of environmental regulations.

Our total sales volume was similar, increasing 1% from the first six months of 2017 to the first six months of 2018, due primarily to higher sales volume in our granular urea and Other segments, partially offset by lower ammonia and AN sales volumes.

41

CF INDUSTRIES HOLDINGS, INC.

Cost of Sales

Our total cost of sales decreased$126 million, or 7%, from the first six months of 2017 to the first six months of 2018. The decrease in our cost of sales was primarily due to an unrealized net mark-to-market gain on natural gas derivatives in the first six months of 2018 compared to a loss in the same period of 2017 and the impact of lower realized natural gas costs, including the impact of realized derivatives. These decreases were partially offset by higher costs related to plant turnarounds and disruptions. The cost of sales per ton averaged $178 in the first six months of 2018, a 7%decrease from $192 per ton in the same period of 2017. The first six months of 2018 included an $8 million unrealized net mark-to-market gain compared to a $71 million unrealized net mark-to-market loss in the first six months of 2017. Additionally, realized natural gas costs, including the impact of realized derivatives, decreased 11% from $3.51 per MMBtu in the first six months of 2017 to $3.11 in the first six months of 2018.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $15 million to $110 million in the first six months of 2018 as compared to $95 million in the comparable period of 2017. The increase was due primarily to certain corporate initiatives, costs for various legal services associated with the acquisition of the publicly traded common units of TNCLP and higher employee costs.

Other Operating—Net

Other operating—net was $18 million of income in the first six months of 2018 compared to $16 million of expense in the comparable period of 2017. The income in the first six months of 2018 was due to the combination of changes in legal reserves, unrealized foreign currency gains pertaining to British pound denominated intercompany loans that have not been permanently invested, and a gain due to the recovery of certain precious metals used in the manufacturing process.

Equity in Earnings (Loss) of Operating Affiliates

Equity in earnings of operating affiliates was $25 million in the first six months of 2018 compared to a loss of $3 million in the first six months of 2017. Earnings in the first six months of 2018 includes approximately $19 million related to the net after-tax impact of a settlement reached between NGC and PLNL of an arbitration proceeding regarding PLNL’s claims for damages due to historical natural gas supply curtailments. See above under “Items Affecting Comparability of Results—PLNL settlement income” for additional information.

During the second quarter of 2017, PLNL recorded a tax contingency accrual related to a tax assessment against PLNL, which reduced our equity in earnings of PLNL for the six months ended June 30, 2017 by approximately $7 million reflecting our 50% ownership interest. See above under “Items Affecting Comparability of Results—Equity method investment tax contingency accrual” for additional information.

Interest Expense—Net

Net interest expense was $116 million in the first six months of 2018 compared to $157 million in the first six months of 2017. The $41 milliondecrease is due primarily to our redemption in December 2017 of all of the 2018 Notes and our December 2017 purchase of approximately $300 million aggregate principal amount of the 2020 Notes.

Income Taxes

For the six months ended June 30, 2018, we recorded an income tax provision of $61 million on pre-tax income of $323 million, or an effective tax rate of 18.8%, compared to an income tax benefit of $8 million on pre-tax income of $7 million, or an effective tax rate of (119.1%), for the six months ended June 30, 2017. Our effective tax rate in the first six months of 2018 is based on the U.S. federal tax rate of 21% as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, as compared to the U.S. federal tax rate of 35% that was applicable in the first six months of 2017.

Our effective tax rate in both periods is impacted by earnings attributable to the noncontrolling interests in CFN and TNCLP, as our consolidated income tax provision (benefit) does not include a tax provision on the earnings attributable to the noncontrolling interests. Our effective tax rate for the six months ended June 30, 2018 and 2017, exclusive of the earnings attributable to the noncontrolling interests of $51 million and $35 million, respectively, would be 22.4% and 28.1%, respectively.

On April 2, 2018, we acquired the TNCLP Public Units. Our effective tax rate in the second quarter of 2018 is impacted by a $20 million reduction to our deferred tax liability as a result of the change in our effective state income tax rate as a result of the implementation of legal entity structure changes related to the acquisition.

42

CF INDUSTRIES HOLDINGS, INC.

The effective tax rate for the six months ended June 30, 2017 was also impacted by the tax contingency accrual of $7 million recorded by PLNL, which reduced our earnings before income taxes but did not change our income tax provision as the adjustment was not tax effected.

See Note 8—Equity Method Investments, Note 10—Income Taxes and Note 14—Noncontrolling Interests for additional information.

Net Earnings Attributable to Noncontrolling Interests

Net earnings attributable to noncontrolling interests increased$16 million in the first six months of 2018 compared to the first six months of 2017 due to higher earnings from CFN driven by higher average selling prices due to the impact of a tighter global nitrogen supply and demand balance and lower natural gas prices, partially offset by the reduction in noncontrolling interests due to the April 2, 2018 purchase of the noncontrolling interests in TNCLP.

Diluted Net Earnings (Loss) Per Share Attributable to Common Stockholders

Diluted net earnings (loss) per share attributable to common stockholders increased $0.99 to $0.90 per share in the first six months of 2018 from $(0.09) per share in the first six months of 2017. This increase is due to higher gross margin primarily driven by higher selling prices due to the impact of a tighter global nitrogen supply and demand balance, the impact of higher unrealized net mark-to-market gains on natural gas derivatives, and lower realized natural gas costs, including the impact of realized derivatives.

Operating Results by Business Segment

Our reportable segments consist of ammonia, granular urea, UAN, AN and Other. These segments are differentiated by products. 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.

Second Quarter of 2018 Compared to Second Quarter of 2017

Net Sales.    Total net sales in the ammonia segment decreased by $15 million, or 4%, in the second quarter of 2018 from the second quarter of 2017 due primarily to a 5%decrease in sales volume partially offset by a 1%increase in average selling prices. Sales volume in the second quarter was impacted by lower supply availability.

Cost of Sales.    Cost of sales in our ammonia segment averaged $249 per ton in the second quarter of 2018, a 5%decrease from $262 per ton in the same quarter of 2017. The decrease was due primarily to lower realized natural gas costs and an unrealized net mark-to-market gain on natural gas derivatives in the second quarter of 2018 compared to a loss in the comparable period of 2017. These decreases were partially offset by higher costs associated with plant turnarounds and disruptions during the second quarter of 2018.

Six Months Ended June 30, 2018 Compared to Six Months Ended June 30, 2017

Net Sales.    Total net sales in the ammonia segment decreased by $85 million, or 13%, in the six months ended June 30, 2018 from the six months ended June 30, 2017 due primarily to a 15%decrease in sales volume partially offset by a 3%increase in average selling prices. Sales volume was lower as strong ammonia movement in the fourth quarter of 2017, which resulted in 2018 beginning inventory being lower than at the beginning of 2017, coupled with lower production volume in 2018, caused less ammonia available for sale. The increase in selling prices was due to the impact of a tighter global nitrogen supply and demand balance.

Cost of Sales.    Cost of sales in our ammonia segment averaged $261 per ton in the six months ended June 30, 2018, a 5%decrease from $274 per ton in the six months ended June 30, 2017. The decrease was due primarily to a combination of factors, including lower realized natural gas costs, and an unrealized net mark-to-market gain on natural gas derivatives in the

six months ended June 30, 2018 compared to a loss in the comparable period of 2017. These decreases were partially offset by higher costs associated with plant turnarounds and disruptions during 2018, including disruptions at our Donaldsonville and Yazoo City plants due to unseasonably cold weather early in the first quarter of 2018.

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.

This decrease was partially offset by an increase in average selling prices of 6% due primarily to the impact of a tighter global nitrogen supply and demand balance.

Cost of Sales.     Total cost of sales in our AN segment averaged $193 per ton in the six months ended June 30, 2018, a 3%increase from $188 per ton in the comparable period of 2017. The increase was due primarily to the foreign exchange rate changes between the U.S. dollar and the British pound and higher realized natural gas costs in the United Kingdom, partially offset by a lower unrealized net mark-to-market loss on natural gas derivatives in the six months ended June 30, 2017.

Second Quarter of 2018 Compared to Second Quarter of 2017

Net Sales.    Total net sales in our Other segment increased by $25 million, or 32%, in the second quarter of 2018 from the second quarter of 2017 due to a 24%increase in sales volume and a 7%increase in average selling prices. The increase in sales volume was due primarily to an increase in nitric acid and DEF sales volume. Demand for DEF in North America continues to grow, which is supported by the increase in DEF production as a result of our new DEF unit at our Donaldsonville facility that came on line in the second quarter of 2017. The increase in average selling prices is due to the impact of a tighter global nitrogen supply and demand balance.

Cost of Sales.    Cost of sales in our Other segment averaged $139 per ton in the second quarter of 2018, an 8%increase from $129 per ton in the second quarter of 2017 due primarily to the mix of products sold and higher U.K. natural gas costs, partially offset by the impact of an unrealized net mark-to-market gain on natural gas derivatives in the second quarter of 2018 compared to a loss in the comparable period of 2017.

Six Months Ended June 30, 2018 Compared to Six Months Ended June 30, 2017

Net Sales.    Total net sales in our Other segment increased by $48 million, or 31%, in the six months ended June 30, 2018 from the six months ended June 30, 2017 due to a 25%increase in sales volume and a 4%increase in average selling prices. The increase in sales volume was due primarily to an increase in DEF and nitric acid sales volume. The increase in average selling prices is due to the impact of a tighter global nitrogen supply and demand balance.

Cost of Sales.    Cost of sales in our Other segment averaged $144 per ton in the six months ended June 30, 2018, a 5%increase from $137 per ton in the six months ended June 30, 2017 due primarily to the mix of products sold, foreign exchange rate changes between the U.S. dollar and the British pound, and higher U.K. natural gas costs, partially offset by the impact of an unrealized net mark-to-market gain on natural gas derivatives in the six months ended June 30, 2018 compared to a loss in the comparable period of 2017.

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.

On December 1, 2017, we redeemed all of the $800 million outstanding principal amount of the 2018 Notes in accordance with the optional redemption provisions provided in the indenture. The total aggregate redemption price was approximately $817 million. On December 26, 2017, we purchased approximately $300 million of the $800 million outstanding aggregate principal amount of the 2020 Notes at a total purchase price of approximately $331 million.

On April 2, 2018, we purchased all of the 4,612,562 publicly traded common units of TNCLP (the Public Units) for $388 million. See discussion under “Purchase of Publicly Traded Common Units of TNCLP,” below, for further information.

At June 30, 2018, we were in compliance with all applicable covenant requirements under our Revolving Credit Agreement, Public Senior Notes and Senior Secured Notes. There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2018 or December 31, 2017, or during the six months ended June 30, 2018. See discussion under “Debt,” below, for further information.

Our cash and cash equivalents balance was $728 million and $835 million as of June 30, 2018 and December 31, 2017, respectively.

Cash Equivalents

Cash equivalents include highly liquid investments that are readily convertible to known amounts of cash with original maturities of three months or less. Under our short-term investment policy, we may invest our cash balances, either directly or through mutual funds, in several types of investment-grade securities, including notes and bonds issued by governmental entities or corporations. Securities issued by governmental entities include those issued directly by the U.S. and Canadian federal governments; those issued by state, local or other governmental entities; and those guaranteed by entities affiliated with governmental entities.

Capital Spending

We make capital expenditures to sustain our asset base, increase our capacity, improve plant efficiency and comply with various environmental, health and safety requirements. Capital expenditures totaled $145 million in the first six months of 2018 compared to $185 million in the first six months of 2017.

Full year capital expenditures for new activity in 2018 are estimated to be in the range of $400 to $450 million. 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, delay in the receipt of equipment, 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.

Purchase of Publicly Traded Common Units of TNCLP

On February 7, 2018, we announced that, in accordance with the terms of TNCLP’s First Amended and Restated Agreement of Limited Partnership (as amended by Amendment No. 1 to the First Amended and Restated Agreement of Limited Partnership), TNGP elected to exercise its right to purchase the Public Units. TNGP completed its purchase of the Public Units on April 2, 2018 (the Purchase), for an aggregate cash purchase price of $388 million. We funded the Purchase with cash on hand. Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP.

Revolving Credit Agreement

We have a senior secured revolving credit agreement (the Revolving Credit Agreement) providing for a revolving credit facility of up to $750 million with a maturity of September 18, 2020. The Revolving Credit Agreement includes a letter of credit sub-limit of $125 million. Borrowings under the Revolving Credit Agreement may be used for working capital and general corporate purposes. CF Industries is the borrower under the Revolving Credit Agreement and may also designate as borrowers one or more wholly owned subsidiaries that are organized in the United States or any state thereof, or the District of Columbia.

Borrowings under the Revolving Credit Agreement may be denominated in U.S. dollars, Canadian dollars, euro and British pounds, and bear interest at a per annum rate equal to an applicable eurocurrency rate or base rate plus, in either case, a specified margin, and the borrowers are required to pay an undrawn commitment fee on the undrawn portion of the commitments under the Revolving Credit Agreement and customary letter of credit fees. The specified margin and the amount of the commitment fee depend on CF Holdings’ credit rating at the time.

The guarantors under the Revolving Credit Agreement are currently comprised of CF Holdings and CF Holdings’ wholly owned subsidiaries CF Industries Enterprises, LLC (CFE), CF Industries Sales, LLC (CFS) and CF USA Holdings, LLC (CF USA).

As of June 30, 2018, we had excess borrowing capacity under the Revolving Credit Agreement of $745 million (net of outstanding letters of credit of $5 million). There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2018 or December 31, 2017, or during the six months ended June 30, 2018.

The Revolving Credit Agreement contains representations and warranties and affirmative and negative covenants, including financial covenants. As of June 30, 2018, we were in compliance with all covenants under the Revolving Credit Agreement.

Letters of Credit

In addition to the letters of credit outstanding under the Revolving Credit Agreement, as described above, we have also entered into a bilateral agreement with capacity to issue letters of credit up to $125 million (reflecting an increase of $50 million in March 2018). As of June 30, 2018, approximately $119 million of letters of credit were outstanding under this agreement.

Public Senior Notes

Under the indentures (including the applicable supplemental indentures) governing our senior notes due 2020, 2023, 2034, 2043 and 2044 (the Public Senior Notes), each series of Public Senior Notes is guaranteed by CF Holdings and CF Holdings’ wholly owned subsidiaries CFE, CFS and CF USA. CFE, CFS and CF USA became subsidiary guarantors of the Public Senior Notes as a result of their becoming guarantors under the Revolving Credit Agreement.

Interest on the Public Senior Notes is payable semiannually, and the Public 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.

Senior Secured Notes

On November 21, 2016, CF Industries issued $500 million aggregate principal amount of 3.400% senior secured notes due 2021 (the 2021 Notes) and $750 million aggregate principal amount of 4.500% senior secured notes due 2026 (the 2026 Notes, and together with the 2021 Notes, the Senior Secured Notes). CF Holdings and the subsidiary guarantors of the Public Senior Notes are also guarantors of the Senior Secured Notes.

Interest on the Senior Secured Notes is payable semiannually on December 1 and June 1 beginning on June 1, 2017, and the Senior Secured Notes are redeemable at our option, in whole at any time or in part from time to time, at specified make-whole redemption prices.

Forward Sales and Customer Advances

We offer our customers the opportunity to purchase products from us 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 June 30, 2018 and December 31, 2017, we had $21 million and $89 million, respectively, in customer advances on our consolidated balance sheets.

While customer advances are a 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. During periods of declining prices, customers tend to delay purchasing fertilizer in anticipation that prices in the future will be lower than the current prices. 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 the Revolving 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. From time to time, we also use derivative financial instruments to reduce our exposure to changes in foreign currency exchange rates. Volatility in reported quarterly earnings can result from the unrealized mark-to-market adjustments in the value of the derivatives. In the three and six months ended June 30, 2018, we recognized unrealized net mark-to-market gains on derivative financial instruments of $5 million and $8 million, respectively. In the three and six months ended June 30, 2017, we recognized unrealized net mark-to-market losses on derivative financial instruments of $18 million and $71 million, respectively. These amounts are reflected in cost of sales in our consolidated statements of operations.

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 International Swaps and Derivatives Association (ISDA)

51

CF INDUSTRIES HOLDINGS, INC.

agreements. The ISDA agreements are master netting arrangements commonly used for over-the-counter 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.

The ISDA agreements for most of our derivative instruments contain credit-risk-related contingent features, such as cross default provisions and credit support thresholds. 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. The Revolving Credit Agreement, at any time when it is secured, provides a cross collateral feature for those of our derivatives that are with counterparties that are party to, or affiliates of parties to, the Revolving Credit Agreement so that no separate collateral would be required for those counterparties in connection with such derivatives. In the event the Revolving Credit Agreement becomes unsecured, separate collateral could be required in connection with such derivatives.

As of June 30, 2018 and December 31, 2017, the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was $4 million and $12 million, respectively, which also approximates the fair value of the maximum amount of additional collateral that would need to be posted or assets needed to settle the obligations if the credit-risk-related contingent features were triggered at the reporting dates. As of June 30, 2018 and December 31, 2017, we had open natural gas derivative contracts, including natural gas fixed price swaps and natural gas basis swaps, for 19.6 million MMBtus and 35.9 million MMBtus, respectively. As of June 30, 2018 and December 31, 2017, we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with certain of our 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.

Defined Benefit Pension Plans

We contributed $17 million to our pension plans during the six months ended June 30, 2018. Over the remainder of 2018, we expect to contribute an additional $24 million to our pension plans, or a total of approximately $41 million for the full year 2018.

Distribution on Noncontrolling Interest in CFN

In the third quarter of 2018, the CFN Board of Managers approved semi-annual distribution payments for the distribution period ended June 30, 2018 in accordance with the Second Amended and Restated Limited Liability Company Agreement of CFN, as amended. On July 31, 2018, CFN distributed $79 million to CHS for the distribution period ended June 30, 2018.

Cash Flows

Operating Activities

Net cash provided by operating activities during the first six months of 2018 was $598 million as compared to $1,187 million in the first six months of 2017. The decrease of $589 million was due primarily to unfavorable working capital changes partially offset by higher net earnings during the first six months of 2018. Unfavorable working capital changes included the receipt in 2017 of our $815 million income tax refund as a result of the claim to carry back the 2016 federal tax loss to prior income tax years.

Investing Activities

Net cash used in investing activities was $118 million in the first six months of 2018 as compared to $158 million in the first six months of 2017. The $40 million decrease is due primarily to lower capital expenditures. During the first six months of 2018, capital expenditures totaled $145 million compared to $185 million in the first six months of 2017.

Financing Activities

Net cash used in financing activities was $583 million in the first six months of 2018 compared to $199 million in the same period of 2017. Dividends paid on common stock in each of the six-month periods ended June 30, 2018 and 2017 were $140 million. Net cash used in financing activities in the first six months of 2018 included $388 million related to our acquisition of all of the outstanding publicly traded common units of TNCLP.

Contractual Obligations

As of June 30, 2018, there have been no material changes outside the ordinary course of business to our contractual obligations as described in our 2017 Annual Report on Form 10-K filed with the SEC on February 22, 2018.

52

CF INDUSTRIES HOLDINGS, INC.

Off-Balance Sheet Arrangements

We have operating leases for certain property and equipment under various noncancelable agreements, including rail car leases and barge tow charters that are utilized for the distribution of our products. The rail car leases currently have minimum terms ranging from one to eleven years and the barge charter commitments currently have terms ranging from one 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 five 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 included in our 2017 Annual Report on Form 10-K filed with the SEC on February 22, 2018 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 six months of 2018.

Recent Accounting Pronouncements

See Note 2—New Accounting Standards for a discussion of recent accounting pronouncements.

Subsequent Event

On August 1, 2018, our board of directors authorized the repurchase of up to $500 million of CF Holdings common stock through June 30, 2020. Repurchases under this program may be made from time to time in the open market, through privately negotiated transactions, 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.

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 nitrogen-based fertilizers 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, UAN (32%), and AN by approximately $32, $22, $14 and $15, 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 with the use of derivative financial instruments. The derivative instruments that we use are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options. These derivatives settle using primarily NYMEX futures price indexes, which represent the basis for fair value at any given time. The contracts represent anticipated natural gas needs for future periods and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods. As of June 30, 2018, we had natural gas NYMEX fixed price swaps covering periods through December 2018 and natural gas basis swaps covering certain periods through March 2019.

As of June 30, 2018 and December 31, 2017, we had open natural gas derivative contracts, including natural gas fixed price swaps and natural gas basis swaps, for 19.6 million MMBtus and 35.9 million MMBtus, respectively. A $1.00 per MMBtu increase in the forward curve prices of natural gas at June 30, 2018 would result in a favorable change in the fair value of these derivative positions of $17 million, and a $1.00 per MMBtu decrease in the forward curve prices of natural gas would change their fair value unfavorably by $17 million.

From time to time we may purchase nitrogen products on the open market to augment or replace production at our facilities.

Interest Rate Fluctuations

As of June 30, 2018, we had seven series of senior notes totaling $4.75 billion of principal outstanding with maturity dates of May 1, 2020, December 1, 2021, June 1, 2023, December 1, 2026, March 15, 2034, June 1, 2043 and March 15, 2044.

ITEM 4.    CONTROLS AND PROCEDURES.

(a)    Disclosure Controls and Procedures.  The Company’s management, with the participation of the Company’s principal executive officer and principal 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 principal executive officer and principal 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 principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

(b)    Changes in 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 June 30, 2018 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS.

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. Various subsidiaries of CF Industries Holdings, Inc. (the CF Entities) have been named as defendants along with other companies in lawsuits filed in 2013, 2014 and 2015 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 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, and breach of warranty under Texas law. Although we do not own or operate the facility or directly sell our products to West Fertilizer Co., products that the CF Entities 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.

The Court granted in part and denied in part the CF Entities’ Motions for Summary Judgment in August 2015. Over two hundred cases have been resolved pursuant to confidential settlements that have been or we expect will be fully funded by insurance. The remaining cases are in various stages of discovery and pre-trial proceedings. There is no trial date currently set; however, we anticipate that the Court will schedule a trial sometime in the beginning of 2019. We believe we have strong legal and factual defenses and intend to continue defending the CF Entities vigorously in the pending lawsuits. The Company cannot provide a range of reasonably possible loss due to the lack of damages discovery for many of the remaining claims and the uncertain nature of this litigation, including uncertainties around the potential allocation of responsibility by a jury to other defendants or responsible third parties. The recognition of a potential loss in the future in the West Fertilizer Co. litigation could negatively affect our results in the period of recognition. However, based upon currently available information, including available insurance coverage, we do not believe that this litigation will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Exhibit 10.1

Amendment to

CF Industries Holdings, Inc.

2005 Equity and Incentive Plan

WHEREAS, the Board of Directors (the “Board”) of CF Industries Holdings, Inc. (the “Company”) has determined that it is in the best interest of the Company that the CF Industries Holdings, Inc. 2005 Equity and Incentive Plan (the “Plan”) be amended to revise the tax withholding provisions set forth in Section 8(c) of the Plan; and

WHEREAS, the Board has the authority under Section 8(d)(ii) of the Plan to amend the Plan.

NOW, THEREFORE, pursuant to Section 8(d)(ii) thereof, the Plan is hereby amended as set forth below.

1.Section 8(c) of the Plan is amended in its entirety to read as follows:

(c)Taxes. The Company or any Subsidiary of the Company is authorized to withhold from any Award granted, any payment relating to an Award under the Plan, including from a distribution of Stock, or any other payment to a Grantee, amounts of withholding and other taxes due in connection with any transaction involving an Award, and to take such other action as the Committee may deem advisable to enable the Company and Grantees to satisfy obligations for the payment of withholding taxes and other tax obligations relating to any Award. This authority shall include authority to withhold or receive Stock or other property and to make cash payments in respect thereof in satisfaction of a Grantee’s tax obligations. The Committee may provide in the Award Agreement that in the event that a Grantee is required to pay any amount to be withheld in connection with the issuance of shares of Stock in settlement or exercise of an Award, the Grantee shall or may satisfy such obligation (in whole or in part) by electing to have withheld a portion of the shares of Stock otherwise to be received upon settlement or exercise of such Award equal to an amount no greater than the maximum statutory tax rate applicable to such Grantee in all relevant jurisdictions and in all cases reduced by the amount of any withholding obligation a Grantee satisfies by cash payment to the Company. All Awards made under the Plan are intended to be exempt from, or to comply with, the requirements of Section 409A of the Code and any regulations or guidance promulgated thereunder and the Plan and such Awards shall be interpreted in a manner consistent with such interpretation.

2.Effect on Plan. Except as expressly amended hereby, the Plan shall remain in full force and effect.

3. Effective Date. The effective date of this Amendment to the Plan shall be July 11, 2018.

IN WITNESS WHEREOF, the Company has caused this Amendment to be executed by a duly authorized representative of the Company, effective as of the Effective Date.

[Letterhead of CF Industries Holdings, Inc.]

July 19, 2018

[Participant]

[Address]

Re: Non-Qualified Stock Option Award Agreement Amendment

Dear [Participant]:

The Board of Directors of CF Industries Holdings, Inc. (the “Company”) has recently approved an amendment to the terms of your outstanding stock options previously granted to you pursuant to the Company’s equity plans.

The amendment would give you the ability to satisfy the tax withholding obligation that you will incur upon the exercise of your options in one of three ways:

• by providing the Company with a cash payment at the time of exercise in an amount determined by applying the statutory minimum rate of withholding;

• by electing to have shares withheld by the Company at the time of exercise, with the number of shares to be withheld determined by applying the same statutory minimum rate of withholding; or

• by electing to have shares withheld by the Company at the time of exercise, with the number of shares to be withheld determined by instead applying the lesser of the maximum statutory tax rate applicable to you or the amount of withholding determined on the basis of your most recent U.S. Form W-4 (or other local country equivalent) provided to the Company.

Previously, before this amendment, your stock option award agreements only gave you the first two alternatives listed above. The advantage for you of this new third alternative is that the rate to be applied may be higher than the statutory minimum withholding rate, permitting you to satisfy more of your ultimate tax obligation through the use of withheld shares as opposed to having to use your personal cash resources for this purpose. Depending on your personal tax situation, you may or may not have a higher withholding rate under the third alternative, but this amendment gives you an additional choice that you may wish to use if it would be beneficial for you.

[Participant]

July 19, 2018

Page 2

The amendment would also add this third alternative to the “automatic exercise” feature of your stock options. (This automatic exercise feature is essentially a “fail-safe,” protecting you against certain situations where your stock options are “in the money,” and approaching the end of their term, in order to ensure that your options are exercised for your benefit before they would otherwise expire.)

Accordingly, if you countersign and return this letter agreement, each of your outstanding stock option award agreements will be amended to include the provisions set forth on Exhibit A in lieu of the current tax withholding provisions set forth in your agreements and the provisions set forth on Exhibit B in lieu of the current “automatic exercise” provisions set forth in your agreements.

The provisions set forth in Exhibits A and B hereto are incorporated by reference and made part of each of your stock option award agreements (collectively, your “Amended Award Agreements”). Except as specifically amended by this letter agreement, each of your Amended Award Agreements otherwise remains in force and effect in accordance with its current terms.

This letter agreement and the terms of the Amended Award Agreements and the Company equity plans under which the Amended Award Agreements were granted contain the entire understanding between you and the Company on the subject matter of this letter agreement, and there are no other agreements or understandings between you and the Company with respect to the subject matter of this letter agreement. No alteration of modification of this letter agreement shall be valid except by a subsequent written instrument executed by you and the Company.

Please confirm your agreement with the content of this letter agreement by countersigning and returning a copy of this letter to me.

If you have any questions regarding this letter agreement or your Amended Award Agreements, please call me at (847) 405-2510.

Sincerely,

Susan L. Menzel

Senior Vice President,

Human Resources

Exhibit A

Amended Tax Withholding Provision

“The Company or a Subsidiary shall withhold all applicable taxes or other amounts required by law from all amounts paid or delivered in respect of the Option. The Optionee may satisfy the withholding obligation by electing to pay the amount of any taxes in cash or by having the Company or applicable subsidiary withhold shares from the Exercised Shares to satisfy the obligation in full or in part. If shares are withheld, such shares shall have a Fair Market Value equal to (a) the minimum statutory amount required to be withheld or, if the Optionee so elects, (b) such greater amount equal to the lesser of (1) the amount permitted to be withheld based on the maximum statutory tax rate applicable to the Optionee in all relevant jurisdictions or (2) the withholding amount determined on the basis of the Optionee’s most recent U.S. Form W-4 (or other local country equivalent) provided to the Company, in all cases reduced by the amount of any withholding obligation the Optionee satisfies by cash payment to the Company. The number of shares used to satisfy any withholding obligation shall be rounded up to the nearest whole number of shares as necessary to avoid fractional shares, with any excess amount refunded in cash to the Optionee. [Additional Language (United Kingdom Only): Optionee agrees to indemnify the Company and any other members of the Group for any tax or social security contributions for which the Optionee is liable but for which the Company or such other member of the Group is required to pay on the Optionee’s behalf in connection with the Option or any shares issued pursuant to the Option granted under this Award Agreement.]”

Exhibit B

Amended Automatic Exercise Provision

“Notwithstanding any other provision of this Agreement, if as of the last trading day prior to the earlier of (i) the Term/Expiration Date or [Alternative A (North America): (ii) the fourth anniversary of the date of Optionee’s Special Retirement (if the Option was granted on or after March 3, 2014) or Ordinary Retirement, the Option has not been exercised] [Alternative B (United Kingdom): (ii) if the Committee so determines, the fourth anniversary of the date of Optionee’s retirement, the Option has not been exercised] and the then Fair Market Value of a share exceeds the per share exercise price by at least $.01 (such expiring portion of the option that is so “in-the-money,” an “Auto-Exercise Eligible Option”), Optionee will be deemed to have automatically exercised such Auto-Exercise Eligible Option (to the extent it has not previously been exercised or forfeited) in accordance with the provisions of this paragraph. In the event of an automatic exercise pursuant to this paragraph, the Company will reduce the number of Exercised Shares issued to Optionee upon such automatic exercise of the Auto-Exercise Eligible Option by a number of Exercised Shares having a Fair Market Value equal to the aggregate exercise price for such Exercised Shares in order to satisfy the aggregated exercise price obligation for the Auto-Exercise Eligible Option. Further, the Company shall reduce the number of Exercised Shares issued to the Optionee by that number of Exercised Shares having an aggregate Fair Market Value equal to the minimum statutory tax withholding obligation arising upon the automatic exercise. The number of shares so held back shall be rounded up to the nearest whole number as necessary to avoid fractional shares and any excess amount held back shall be refunded in cash to Optionee. The foregoing notwithstanding, Optionee may notify the Company, in writing, in advance, that (x) the Optionee elects that if shares are withheld, such shares shall have a Fair Market Value equal to such greater amount equal to the lesser of (1) the amount permitted to be withheld based on the maximum statutory tax rate applicable to the Optionee in all relevant jurisdictions or (2) the withholding amount determined on the basis of the Optionee’s most recent U.S. Form W-4 (or other local country equivalent) provided to the Company, (y) Optionee wishes to satisfy the aggregated exercise price obligation and/or the minimum statutory tax withholding obligation in whole or in part through payment in cash rather than through reduction in the number of Exercised Shares issued to Optionee or, alternatively, (z) that Optionee does not wish for the Auto-Exercise Eligible Option to be exercised at all. In its discretion, the Company may determine to cease automatically exercising options, including the Option, at any time.”

Background and Basis of Presentation

 Background and Basis of Presentation

We are a leading global fertilizer and chemical company. Our 3,000 employees operate world-class manufacturing complexes in Canada, the United Kingdom and the United States. Our principal customers are cooperatives, independent fertilizer distributors, farmers and industrial users. Our principal nitrogen fertilizer products are ammonia, granular urea, urea ammonium nitrate solution (UAN) and ammonium nitrate (AN). Our other nitrogen products include diesel exhaust fluid (DEF), urea liquor, nitric acid and aqua ammonia, which are sold primarily to our industrial customers, and compound fertilizer products (NPKs), which are solid granular fertilizer products for which the nutrient content is a combination of nitrogen, phosphorus, and potassium. We serve our customers in North America through our production, storage, transportation and distribution network. We also reach a global customer base with exports from our Donaldsonville, Louisiana, plant, the world’s largest and most flexible nitrogen complex. Additionally, we move product to international destinations from our Verdigris, Oklahoma, facility, our Yazoo City, Mississippi, facility, and our Billingham and Ince facilities in the United Kingdom, and from a joint venture ammonia facility in the Republic of Trinidad and Tobago in which we own a 50 percent interest.

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.

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, 2017, in accordance with U.S. generally accepted accounting principles (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 2017 Annual Report on Form 10-K filed with the SEC on February 22, 2018. 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 defined benefit pension and other postretirement benefit plans and the assumptions used in the valuation of stock-based compensation awards granted to employees.

During the first quarter of 2018, we adopted Accounting Standards Update (ASU) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. As a result, in our consolidated statements of cash flows for the six months ended June 30, 2017, we have reclassified $1 million of withdrawals from restricted cash funds, previously classified as cash flows provided by investing activities, to be included in the reconciliation of the beginning and ending balances of cash, cash equivalents and restricted cash. See Note 2—New Accounting Standards for additional information.

During the first quarter of 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. As a result, we reclassified certain amounts in our consolidated statements of operations for the three and six months ended June 30, 2017. See Note 2—New Accounting Standards for additional information.

New Accounting Standards

Recently Adopted Pronouncements

On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments. Additionally, the costs to obtain and fulfill a contract, including assets to be recognized, are to be capitalized and such capitalized costs should be disclosed. In 2016, the Financial Accounting Standards Board (FASB) issued additional ASUs that enhanced the operability of the principal versus agent guidance in ASU No. 2014-09 by clarifying that an entity should consider the nature of each good or service promised to a customer at the individual good or service level, clarified that ASU No. 2014-09 should not be applied to immaterial performance obligations, and enhanced the guidance around the treatment of shipping costs incurred to fulfill performance obligations. Our adoption of this ASU, utilizing the modified retrospective approach on contracts that were not completed as of January 1, 2018, resulted in a reduction to opening retained earnings of $1 million related to the cumulative difference between ASC Topic 605 and ASC Topic 606. See Note 3—Revenue Recognition for additional information.

On January 1, 2018, we adopted ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities, which changes the income statement impact of equity investments held by an entity. The amendments require the unrealized gains or unrealized losses of equity instruments measured at fair value to be recognized in net income. Our adoption of this ASU resulted in an increase to opening retained earnings of $1 million representing the cumulative effect of unrealized gains from equity securities from accumulated other comprehensive income (loss).

On January 1, 2018, we adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash - a consensus of the FASB Emerging Issues Task Force, which requires that the statement of cash flows include amounts described as restricted cash and restricted cash equivalents as part of cash and cash equivalents when reconciling the beginning and ending period total amounts. Upon adoption of this ASU, $1 million of withdrawals from restricted cash funds previously reflected as cash provided by investing activities for the six months ended June 30, 2017, and our restricted cash of $5 million and $4 million as of December 31, 2016 and June 30, 2017, respectively, were reclassified to be included within the reconciliation of beginning and ending cash, cash equivalents and restricted cash balances on our consolidated statement of cash flows.

On January 1, 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changed the presentation of net benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Only service cost can be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net benefit cost must be presented separately outside of operating income. Additionally, only service costs may be capitalized on the balance sheet. Our adoption of this ASU was applied retrospectively for the income statement classification requirements and prospectively for the capitalization guidance, which resulted in $1 million and $2 million of net benefit cost previously recognized in cost of sales for the three and six months ended June 30, 2017, respectively, to be reclassified to other non-operating on our consolidated statements of operations.

On January 1, 2018, we adopted ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Our adoption of this ASU had no impact on our consolidated financial statements.

Recently Issued Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in ASC Topic 840, Leases. This ASU will require lessees to recognize the rights and obligations resulting from virtually all leases (other than leases that meet the definition of a short-term lease) on their balance sheets as right-of-use assets with corresponding lease liabilities. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of income and expense recognized and expected to be recognized from existing contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and required the modified retrospective method of adoption. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides the option to adopt ASU No. 2016-02 retrospectively for each prior period presented or as of the adoption date with a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. While we are continuing to evaluate the impact of the adoption of these ASUs on our consolidated financial statements, we currently believe the most significant change relates to the recognition of the right-of-use assets and lease liabilities on our balance sheet for operating leases for certain property and equipment, including transportation equipment utilized for the distribution of our products.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships in order to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and should be applied to existing hedging relationships as of the date of adoption. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and for interim periods therein. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

Revenue Recognition

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

Prior to the adoption of ASC 606, under ASC 605, the basic criteria necessary for revenue recognition were: (1) evidence that a sales arrangement existed, (2) delivery of goods had occurred, (3) the seller's price to the buyer was fixed or determinable, and (4) collectability was reasonably assured. We recognized revenue when these criteria had been met, and when title and risk of loss transferred to the customer, which could be at the plant gate, a distribution facility, a supplier location or a customer destination.

We adopted ASC 606 on January 1, 2018. The revenue that we recognize, both prior to and after the adoption of ASC 606, arises from contracts we have with our customers. Our performance obligations under a contract correspond to each shipment of product that we make to our customer under the contract; as a result, each contract may have more than one performance obligation based on the number of products ordered, the quantity of product to be shipped and the mode of shipment requested by the customer. Control of our products transfers to our customers when the customer is able to direct the use of, and obtain substantially all of the benefits from, our products, which generally occurs at the later of when the customer obtains title to our product or when the customer assumes risk of loss of our product. The transfer of control generally occurs at a point in time upon loading of our product onto transportation equipment or upon delivery to the customer’s intended destination. Once this occurs, we have satisfied our performance obligation and we recognize revenue.

When we enter into a contract with a customer, we are obligated to provide the product during a mutually agreed upon time period. Depending on the terms of the contract, either we or the customer arranges delivery of the product to the customer’s intended destination. In situations where we have agreed to arrange delivery of the product to the customer’s intended destination and control of the product transfers upon loading of our product onto transportation equipment, we have elected to account for any freight income associated with the delivery of these products as freight revenue, consistent with our treatment of this income prior to the adoption of ASC 606, since this activity fulfills our obligation to transfer the product to the customer. For the three and six months ended June 30, 2018, the total amount of freight recognized as revenue was not material.

Certain of our contracts require us to supply products on a continuous basis to the customer. We recognize revenue on these contracts based on the quantity of products transferred to the customer during the period. For the three and six months ended June 30, 2018, the amount of revenue for these types of transactions was $16 million and $41 million, respectively.

From time to time, we will enter the marketplace to purchase the needed product in order to meet our customer contracts. When we purchase product to meet customer contracts, we are the principal in the transaction and recognize revenue on a gross basis. As discussed in Note 8—Equity Method Investments, we have transactions in the normal course of business with Point Lisas Nitrogen Limited (PLNL), reflecting our obligation to purchase 50% of the ammonia produced by PLNL at current market prices. During the six months ended June 30, 2018, other than products purchased from PLNL, we did not purchase any products in the marketplace in order to meet our customer contracts.

Transaction Price

We agree with our customers on the selling price of each transaction. This transaction price is generally based on the product, market conditions, including supply and demand balances, freight arrangements including where control transfers, and customer incentives. In our contracts with customers, we allocate the entire transaction price to the sale of product to the customer, which is the basis for the determination of the relative standalone selling price allocated to each performance obligation. Returns of our product by our customers are permitted only when the product is not to specification, and were not material for the three and six months ended June 30, 2018. Any sales tax, value added tax, and other tax we collect concurrently with our revenue-producing activities are excluded from revenue.

We offer cash incentives to certain customers based on the volume of their purchases over a certain period. These incentives do not provide an option to the customer for additional product. Customer incentives are reported as a reduction in net sales. Accrual of these incentives involves the use of estimates, including how much product the customer will purchase and whether the customer will achieve a certain level of purchases within the incentive period. The balances of customer incentives accrued at June 30, 2018, and December 31, 2017 were not material.

If we had continued to apply legacy revenue recognition guidance for the three and six months ended June 30, 2018, our revenues, gross margin, and net income attributable to common shareholders would not have been materially different. See Note 2—New Accounting Standards for the impact of our adoption of ASU No. 2014-09.

Revenue Disaggregation

We track our revenue by product and by geography. See Note 17—Segment Disclosures for our revenue by reportable segment, which are ammonia, granular urea, UAN, AN, and Other.

The following table summarizes our revenue by product and by geography (based on destination of our shipment) for the three and six months ended June 30, 2018:

	Ammonia		Granular Urea		UAN		AN		Other		Total

Total revenue	$	586	$	624	$	622	$	224	$	201	$	2,257

Accounts Receivable and Customer Advances

Our customers purchase our products through sales on credit or forward sales. Products sold to our customers on credit are recorded as accounts receivable when the customer obtains control of the product. Customers that purchase our products on credit are required to pay in accordance with our customary payment terms, which are generally less than 30 days. For the three and six months ended June 30, 2018, the amount of customer bad debt expense recognized was immaterial.

For forward sales, the customer prepays a portion of the value of the sales contract prior to obtaining control of the product. These prepayments, when received, are recorded as customer advances and are recognized as revenue when the customer obtains control of the product. Forward sales are customarily offered for periods of less than one year in advance of when the customer obtains control of the product.

As of June 30, 2018 and December 31, 2017, we had $21 million and $89 million, respectively, in customer advances on our consolidated balance sheets. The decrease in the balance of customer advances was primarily caused by customers taking delivery of fertilizer during the spring application season. During the six months ended June 30, 2018, all of our customer advances that were recorded as of December 31, 2017 were recognized as revenue.

We have certain customer contracts with performance obligations where if the customer does not take the required amount of product specified in the contract, then the customer is required to make a payment to us, which may vary based upon the terms and conditions of the applicable contract. As of June 30, 2018, excluding contracts with original durations of less than one year, and based on the minimum product tonnage to be sold and current market price estimates, our remaining performance obligations under these contracts are approximately $1.4 billion. We expect to recognize approximately 9% of these performance obligations as revenue during the remainder of 2018, approximately 36% as revenue during 2019 and 2020, approximately 30% as revenue during 2021 and 2022, and the remainder thereafter. If these customers do not fulfill their contractual obligations under such contracts, the legally enforceable minimum amount that they would pay to us under these contracts is approximately $260 million as of June 30, 2018. Other than the performance obligations described above, any performance obligations with our customers that were unfulfilled or partially filled at December 31, 2017 will be satisfied in 2018.

All of our contracts require that the period between the payment for goods and the transfer of those goods to the customer occur within normal contractual terms that do not exceed one year; therefore, we have not adjusted the transaction price of any of our contracts to recognize a significant financing component. We have also expensed any incremental costs associated with obtaining a contract that has a duration of less than one year, and there were no costs capitalized during the six months ended June 30, 2018.

Equity Method Investments and Joint Ventures [Abstract]

Equity Method Investments

Equity Method Investments

We have a 50% ownership interest in PLNL, which operates an ammonia production facility in the Republic of Trinidad and Tobago. We include our share of the net earnings from this equity method investment as an element of earnings from operations because PLNL provides additional production to our operations and is integrated with our other supply chain and sales activities in the ammonia segment.

As of June 30, 2018, the total carrying value of our equity method investment in PLNL was $94 million, $50 million more than our share of PLNL’s book value. The excess is attributable to the purchase accounting impact of our acquisition of the investment in PLNL and reflects the revaluation of property, plant and equipment. The increased basis for property, plant and equipment is being amortized over a remaining period of approximately 15 years. Our equity in earnings of PLNL is different from our ownership interest in income reported by PLNL due to amortization of this basis difference.

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 $9 million and $38 million for the three and six months ended June 30, 2018, respectively, and $24 million and $44 million for the three and six months ended June 30, 2017, respectively.

The Trinidadian tax authority (the Board of Inland Revenue) previously issued a tax assessment against PLNL related to a dispute over whether tax depreciation must be claimed during a tax holiday period that was granted to PLNL under the Trinidadian Fiscal Incentives Act. The tax holiday was granted as an incentive to construct PLNL’s ammonia plant. Based on the facts and circumstances of this matter, PLNL recorded a tax contingency accrual in the second quarter of 2017, which reduced our equity in earnings of PLNL for the three and six months ended June 30, 2017 by approximately $7 million reflecting our 50% ownership interest. In early 2018, PLNL settled this matter with the Board of Inland Revenue for the amounts accrued.

PLNL operates an ammonia plant that relies on natural gas supplied, under a Gas Sales Contract (the NGC Contract), by The National Gas Company of Trinidad and Tobago Limited (NGC). PLNL experienced past curtailments in the supply of natural gas from NGC, which reduced historical ammonia production at PLNL. The NGC Contract had an initial expiration date of September 2018 and was extended on the same terms until September 2023. Any NGC commitment to supply gas beyond 2023 will be based on new agreements. In May 2018, the NGC and PLNL reached a settlement of an arbitration proceeding regarding PLNL’s claims for damages due to the natural gas supply curtailments. The net after-tax impact of the settlement reached between NGC and PLNL that is recognized in our consolidated statements of operations for the three and six months ended June 30, 2018 was an increase in our equity in earnings of operating affiliates of approximately $19 million.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following tables present assets and liabilities included in our consolidated balance sheets as of June 30, 2018 and December 31, 2017 that are recognized at fair value on a recurring basis, and indicate the fair value hierarchy utilized to determine such fair value:

Embedded derivative liability	(25		)	—		(25		)	—

Cash Equivalents

As of June 30, 2018 and December 31, 2017, 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.

Nonqualified Employee Benefit Trusts

We maintain trusts associated with certain nonqualified supplemental pension plans. The fair values of the trust assets are based on daily quoted prices in an active market, which represent the net asset values of the shares held in the trusts, and are included on our consolidated balance sheets in other assets. Debt securities are accounted for as available-for-sale securities. In 2018, as a result of our adoption of ASU 2016-01 on January 1, 2018, changes in the fair value of equity securities in the trust assets are recognized through earnings. See Note 2—New Accounting Standards for additional information.

Derivative Instruments

The derivative instruments that we use are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options traded in the over-the-counter (OTC) markets with multinational commercial banks, other major financial institutions or large energy companies. The natural gas derivative contracts represent anticipated natural gas needs for future periods and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods. 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 independent third party. See Note 13—Derivative Financial Instruments for additional information.

Embedded Derivative Liability

Under the terms of our strategic venture with CHS Inc. (CHS), if our credit rating as determined by two of three specified credit rating agencies is below certain levels, we are required to make a non-refundable yearly payment of $5 million to CHS. Since our credit ratings were below certain levels in 2016 and 2017, we made a payment of $5 million to CHS in each year. These payments will continue on a yearly basis until the earlier of the date that our credit rating is upgraded to or above certain levels by two of the three specified credit rating agencies or February 1, 2026. This obligation is recognized on our consolidated balance sheets as an embedded derivative. As of June 30, 2018 and December 31, 2017, the embedded derivative liability of $26 million and $25 million, respectively, is included in other current liabilities and other liabilities on our consolidated balance sheets. The inputs into the fair value measurement include the probability of future upgrades and downgrades of our credit rating based on historical credit rating movements of other public companies and the discount rates to be applied to potential annual payments based on applicable credit spreads of other public companies at different credit rating levels. Based on these inputs, our fair value measurement is classified as Level 2. For the six months ended June 30, 2018 and 2017, we recognized charges of $1 million and $3 million, respectively, related to the embedded derivative, which are included in other operating—net in our consolidated statement of operations.

See Note 14—Noncontrolling Interests for additional information regarding our strategic venture with CHS.

Financial Instruments

The carrying amount and estimated fair value of our financial instruments are as follows:

	June 30, 2018				December 31, 2017
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(in millions)
Long-term debt	$	4,695	$	4,474	$	4,692	$	4,800

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, they 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.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

We also have assets and liabilities that may be measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment, when there is allocation of purchase price in an acquisition or when a new liability is being established that requires fair value measurement. These include long-lived assets, goodwill and other intangible assets and investments in unconsolidated subsidiaries, such as equity method investments, which may be written down to fair value as a result of impairment. The fair value measurements related to each of these rely primarily on Company-specific inputs and the Company’s assumptions about the use of the assets. Since certain of the Company’s assumptions would involve inputs that are not observable, these fair values would reside within Level 3 of the fair value hierarchy.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

For the three months ended June 30, 2018, we recorded an income tax provision of $44 million on pre-tax income of $218 million, or an effective tax rate of 20.2%, compared to an income tax provision of $5 million on pre-tax income of $29 million, or an effective tax rate of 17.7%, for the three months ended June 30, 2017.

Our effective tax rate in the first six months of 2018 is based on the U.S. federal tax rate of 21% as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, as compared to the U.S. federal tax rate of 35% that was applicable in the first six months of 2017.

Our effective tax rate is impacted by earnings attributable to noncontrolling interests in CF Industries Nitrogen, LLC (CFN) and in the second quarter of 2017 by earnings attributable to the noncontrolling interests in Terra Nitrogen Company, L.P. (TNCLP), as our consolidated income tax provision (benefit) does not include a tax provision on the earnings attributable to the noncontrolling interests. Our effective tax rate for the three months ended June 30, 2018 and 2017, exclusive of the earnings attributable to the noncontrolling interests of $26 million and $21 million, respectively, would be 23.0% and 63.3%, respectively. See Note 14—Noncontrolling Interests for additional information.

On April 2, 2018, we purchased all of the outstanding publicly traded common units of TNCLP. Our effective tax rate in the second quarter of 2018 is impacted by a $20 million reduction to our deferred tax liability due to the change in our effective state income tax rate as a result of the implementation of legal entity structure changes related to the acquisition. See Note 14—Noncontrolling Interests for additional information.

The effective tax rate for the three months ended June 30, 2017 was also impacted by the tax contingency accrual recorded by PLNL, which reduced our earnings before income taxes by $7 million but did not change our income tax provision as the adjustment was not tax effected. See Note 8—Equity Method Investments for additional information.

During the second quarter of 2017, the valuation allowance for the net operating losses of a subsidiary of the Company that we recorded in prior periods was reduced by $12 million as the result of a statutory income tax rate change.

On July 6, 2017, the State of Illinois enacted an income tax rate increase and the impact of approximately $5 million on future tax assets and liabilities was recorded in the period of enactment.

During the third quarter of 2016, one of our Canadian subsidiaries received a Notice of Reassessment from the Canada Revenue Agency (CRA) for tax years 2006 through 2009 asserting a disallowance of certain patronage allocations. The tax assessment of CAD $174 million (or approximately $133 million), including provincial taxes but excluding any interest or penalties, is the result of an audit that was initiated by the CRA in January 2010 and involves the sole issue of whether certain patronage allocations meet the requirements for deductibility under the Income Tax Act of Canada. The reassessment has been appealed and a letter of credit in the amount of CAD $87 million (or approximately $66 million) has been posted. We believe that it is more likely than not that the patronage allocation deduction will ultimately be sustained. In the event that we do not prevail in the appeal, we should be entitled to a U.S. foreign tax credit against any incremental Canadian tax paid. This issue is currently under review by the competent authorities of Canada and the United States.

During the fourth quarter of 2017, we recorded the impact of the Tax Cuts and Jobs Act that was enacted on December 22, 2017, including a provisional amount for the impact of the transition tax liability based on amounts reasonably estimable. We have not recorded measurement period adjustments to this provisional amount in the six months ended June 30, 2018.

Revolving Credit Agreement

We have a senior secured revolving credit agreement (the Revolving Credit Agreement) providing for a revolving credit facility of up to $750 million with a maturity of September 18, 2020. The Revolving Credit Agreement includes a letter of credit sub-limit of $125 million. Borrowings under the Revolving Credit Agreement may be used for working capital and general corporate purposes. CF Industries, the borrower under the Revolving Credit Agreement, may also designate as borrowers one or more wholly owned subsidiaries that are organized in the United States or any state thereof or the District of Columbia.

Borrowings under the Revolving Credit Agreement may be denominated in dollars, Canadian dollars, euros and British pounds, and bear interest at a per annum rate equal to an applicable eurocurrency rate or base rate plus, in either case, a specified margin, and the borrowers are required to pay an undrawn commitment fee on the undrawn portion of the commitments under the Revolving Credit Agreement and customary letter of credit fees. The specified margin and the amount of the commitment fee depend on CF Holdings’ credit rating at the time.

The guarantors under the Revolving Credit Agreement are currently comprised of CF Holdings and CF Holdings’ wholly owned subsidiaries CF Industries Enterprises, LLC (CFE), CF Industries Sales, LLC (CFS) and CF USA Holdings, LLC (CF USA).

As of June 30, 2018, we had excess borrowing capacity under the Revolving Credit Agreement of $745 million (net of outstanding letters of credit of $5 million). There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2018 or December 31, 2017, or during the six months ended June 30, 2018.

The Revolving Credit Agreement contains representations and warranties and affirmative and negative covenants, including financial covenants. As of June 30, 2018, we were in compliance with all covenants under the Revolving Credit Agreement.

Letters of Credit

In addition to the letters of credit outstanding under the Revolving Credit Agreement, as described above, we have also entered into a bilateral agreement with capacity to issue letters of credit up to $125 million (reflecting an increase of $50 million in March 2018). As of June 30, 2018, approximately $119 million of letters of credit were outstanding under this agreement.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

We use derivative financial instruments primarily to reduce our exposure to changes in commodity prices.

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. The derivatives that we use for this purpose are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options 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 recognized in earnings. As of June 30, 2018, we had natural gas NYMEX fixed price swaps covering periods through December 2018 and natural gas basis swaps covering certain periods through March 2019.

As of June 30, 2018 and December 31, 2017, we had open natural gas derivative contracts, including natural gas fixed price swaps and natural gas basis swaps, for 19.6 million MMBtus (millions of British thermal units) and 35.9 million MMBtus, respectively. For the six months ended June 30, 2018, we used natural gas NYMEX fixed price swaps to cover approximately 9% of our natural gas consumption.

The effect of derivatives in our consolidated statements of operations is shown in the table below.

Most of our International Swaps and Derivatives Association (ISDA) agreements contain credit-risk-related contingent features such as cross default provisions and credit support thresholds. 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. The Revolving Credit Agreement, at any time when it is secured, provides a cross collateral feature for those of our derivatives that are with counterparties that are party to, or affiliates of parties to, the Revolving Credit Agreement so that no separate collateral would be required for those counterparties in connection with such derivatives. In the event the Revolving Credit Agreement becomes unsecured, separate collateral could be required in connection with such derivatives. As of June 30, 2018 and December 31, 2017, the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was $4 million and $12 million, respectively, which also approximates the fair value of the maximum amount of additional collateral that would need to be posted or assets needed to settle the obligations if the credit-risk-related contingent features were triggered at the reporting dates. As of June 30, 2018 and December 31, 2017, we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with certain of our 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.

CF Industries Nitrogen, LLC (CFN)

We have a strategic venture with CHS under which they own an equity interest in CFN, a subsidiary of CF Holdings, which represents approximately 11% of the membership interest of CFN. We own the remaining membership interest. Under the terms of CFN’s limited liability company agreement, each member’s interest will reflect, over time, the impact of the profitability of CFN and any member contributions made to, and distributions received from, CFN. For financial reporting purposes, the assets, liabilities and earnings of the strategic venture are consolidated into our financial statements. CHS’ interest in the strategic venture is recorded in noncontrolling interests in our consolidated financial statements. CHS also receives deliveries pursuant to a supply agreement under which CHS has the right to purchase annually from CFN up to approximately 1.1 million tons of granular urea and 580,000 tons of UAN at market prices. As a result of its equity interest in CFN, CHS is entitled to semi-annual cash distributions from CFN. We are also entitled to semi-annual cash distributions from CFN. The amounts of distributions from CFN to us and CHS are based generally on the profitability of CFN and determined based on the volume of granular urea and UAN sold by CFN to us and CHS pursuant to supply agreements, less a formula driven amount based primarily on the cost of natural gas used to produce the granular urea and UAN, and adjusted for the allocation of items such as operational efficiencies and overhead amounts. Additionally, under the terms of the strategic venture, we recognized an embedded derivative related to our credit rating. See Note 9—Fair Value Measurements for additional information.

In the third quarter of 2018, the CFN Board of Managers approved semi-annual distribution payments for the distribution period ended June 30, 2018 in accordance with the Second Amended and Restated Limited Liability Company Agreement of CFN, as amended. On July 31, 2018, CFN distributed $79 million to CHS for the distribution period ended June 30, 2018.

Terra Nitrogen Company, L.P. (TNCLP)

On February 7, 2018, we announced that, in accordance with the terms of TNCLP’s First Amended and Restated Agreement of Limited Partnership (as amended by Amendment No. 1 to the First Amended and Restated Agreement of Limited Partnership, the TNCLP Agreement of Limited Partnership), Terra Nitrogen GP Inc. (TNGP), the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP (the Public Units). TNGP completed its purchase of the Public Units on April 2, 2018 (the Purchase) for an aggregate cash purchase price of $388 million, which was recognized as a reduction in paid-in capital of $62 million; a deferred tax liability of $5 million; and the removal of the TNCLP noncontrolling interests, as shown in the table above. Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP.

Prior to April 2, 2018, TNCLP was a master limited partnership that owned a nitrogen fertilizer manufacturing facility in Verdigris, Oklahoma. We owned approximately 75.3% of TNCLP through general and limited partnership interests and outside investors owned the remaining approximately 24.7% of the limited partnership. For financial reporting purposes, the assets, liabilities and earnings of the partnership were consolidated into our financial statements. The outside investors’ limited partnership interests in the partnership were recorded in noncontrolling interests in our consolidated financial statements. The noncontrolling interest represents the noncontrolling unitholders’ interest (prior to the Purchase) in the earnings and equity of TNCLP. Affiliates of CF Industries were 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.

Prior to April 2, 2018, TNCLP made cash distributions to the general and limited partners based on formulas defined within the TNCLP Agreement of Limited Partnership. Cash available for distribution (Available Cash) was defined in the TNCLP Agreement of Limited Partnership 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 determined in its reasonable discretion to be necessary or appropriate. Changes in working capital affected Available Cash, as increases in the amount of cash invested in working capital items (such as increases in receivables or inventory and decreases in accounts payable) reduced Available Cash, while declines in the amount of cash invested in working capital items increased Available Cash. Cash distributions to the limited partners and general partner varied depending on the extent to which the cumulative distributions exceeded certain target threshold levels set forth in the TNCLP Agreement of Limited Partnership.

In both the first and second quarters of 2017, the minimum quarterly distributions under the TNCLP Agreement of Limited Partnership were satisfied, which entitled TNGP to receive incentive distributions on its general partner interests (in addition to minimum quarterly distributions). TNGP assigned its right to receive such incentive distributions to an affiliate of TNGP that was also an indirect wholly owned subsidiary of CF Holdings. The earnings attributed to our general partner interest in excess of the threshold levels for the six months ended June 30, 2017 was $14 million.

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. Various subsidiaries of CF Industries Holdings, Inc. (the CF Entities) have been named as defendants along with other companies in lawsuits filed in 2013, 2014 and 2015 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 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, and breach of warranty under Texas law. Although we do not own or operate the facility or directly sell our products to West Fertilizer Co., products that the CF Entities 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.

The Court granted in part and denied in part the CF Entities’ Motions for Summary Judgment in August 2015. Over two hundred cases have been resolved pursuant to confidential settlements that have been or we expect will be fully funded by insurance. The remaining cases are in various stages of discovery and pre-trial proceedings. There is no trial date currently set; however, we anticipate that the Court will schedule a trial sometime in the beginning of 2019. We believe we have strong legal and factual defenses and intend to continue defending the CF Entities vigorously in the pending lawsuits. The Company cannot provide a range of reasonably possible loss due to the lack of damages discovery for many of the remaining claims and the uncertain nature of this litigation, including uncertainties around the potential allocation of responsibility by a jury to other defendants or responsible third parties. The recognition of a potential loss in the future in the West Fertilizer Co. litigation could negatively affect our results in the period of recognition. However, based upon currently available information, including available insurance coverage, we do not believe that this litigation will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

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—Ozone Attainment Designation

Our Donaldsonville nitrogen complex is located in a five-parish region near Baton Rouge, Louisiana. On December 15, 2016, the EPA redesignated the Baton Rouge Nonattainment Area as “attainment” with respect to the 2008 8-hour ozone national ambient air quality standard (NAAQS). However, based on 2013-2015 air quality monitoring data, the State of Louisiana recommended that the EPA designate the Baton Rouge area as “non-attainment” pursuant to the updated 2015 8-hour ozone standard. On December 20, 2017, the EPA notified the state of Louisiana that it intends to designate the Baton Rouge area as non-attainment for the 2015 ozone standard. On January 5, 2018, the EPA published notice of a public comment period with respect to the proposed attainment/non-attainment designations of certain air quality regions, including the Baton Rouge area. The EPA subsequently determined, based on certified air emissions data for calendar year 2017, that the air quality monitors for the Baton Rouge area are attaining the 2015 standard. As a result, on April 30, 2018, the EPA Administrator signed a notice designating the Baton Rouge area as “attainment/unclassifiable” with respect to the 2015 ozone standard. Designation of the Baton Rouge area as nonattainment with respect to the 2015 ozone standard could have resulted in more stringent air pollution emissions limits for our existing operation and would have subjected our facilities to more stringent requirements to obtain approvals for plant expansions, or made it more difficult to obtain such approvals.

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. In 2015, we and several other parties received a notice that the U.S. Department of the Interior and other trustees intend to undertake a natural resource damage assessment for 17 former phosphate mines in southeast Idaho, one of which is the former Georgetown Canyon mine. We are not able to estimate at this time our potential liability, if any, with respect to the cleanup of the site or a possible claim for natural resource damages. However, based on currently available information, we do not expect the remedial or financial obligations to which we may be subject involving this or other cleanup sites will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Segment Reporting [Abstract]

Segment Disclosures

Segment Disclosures

Our reportable segments consist of ammonia, granular urea, UAN, AN and Other. These segments are differentiated by products. 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 and six months ended June 30, 2018 and 2017 are presented in the tables below.

Condensed Consolidating Financial Statements

The following condensed consolidating financial information is 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 (i) the senior notes due 2020, 2023, 2034, 2043 and 2044 (described in Note 12—Financing Agreements and referred to in this report as the Public Senior Notes) issued by CF Industries, Inc. (CF Industries), a 100% owned subsidiary of CF Industries Holdings, Inc. (Parent), and guarantees of the Public Senior Notes by Parent and by CFE, CFS and CF USA (the Subsidiary Guarantors), which are 100% owned subsidiaries of Parent, and (ii) debt securities of CF Industries (Other Debt Securities), and guarantees thereof by Parent and the Subsidiary Guarantors, that may be offered and sold from time to time under registration statements that may be filed by Parent, CF Industries and the Subsidiary Guarantors with the SEC.

In the event that a subsidiary of Parent, other than CF Industries, becomes a borrower or a guarantor under the Revolving Credit Agreement (or any renewal, replacement or refinancing thereof), such subsidiary would be required to become a guarantor of the Public Senior Notes, provided that such requirement will no longer apply with respect to the Public Senior Notes due 2023, 2034, 2043 and 2044 following the repayment of the Public Senior Notes due 2020 or the subsidiaries of Parent, other than CF Industries, otherwise becoming no longer subject to such a requirement to guarantee the Public Senior Notes due 2020. The Subsidiary Guarantors became guarantors of the Public Senior Notes as a result of this requirement.

All of the guarantees of the Public Senior Notes are, and we have assumed for purposes of this presentation of condensed consolidating financial information that the guarantees of any Other Debt Securities would be, full and unconditional (as such term is defined in SEC Regulation S-X Rule 3-10(h)) and joint and several. The guarantee of a Subsidiary Guarantor will be automatically released with respect to a series of the Public Senior Notes (1) upon the release, discharge or termination of such Subsidiary Guarantor’s guarantee of the Revolving Credit Agreement (or any renewal, replacement or refinancing thereof), (2) upon legal defeasance with respect to the Public Senior Notes of such series or satisfaction and discharge of the indenture with respect to such series of Public Senior Notes or (3) in the case of the Public Senior Notes due 2023, 2034, 2043 and 2044, upon the discharge, termination or release of, or the release of such Subsidiary Guarantor from its obligations under, such Subsidiary Guarantor’s guarantee of the Public Senior Notes due 2020, including, without limitation, any such discharge, termination or release as a result of retirement, discharge or legal or covenant defeasance of, or satisfaction and discharge of the supplemental indenture governing, the Public Senior Notes due 2020.

For purposes of the presentation of condensed consolidating financial information, the subsidiaries of Parent other than CF Industries and the Subsidiary Guarantors are referred to as the Non-Guarantors.

Presented below are condensed consolidating statements of operations for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors for the three and six months ended June 30, 2018 and 2017, condensed consolidating statements of cash flows for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors for the six months ended June 30, 2018 and 2017, and condensed consolidating balance sheets for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors as of June 30, 2018 and December 31, 2017. The condensed consolidating financial information presented below is not necessarily indicative of the financial position, results of operations, comprehensive income or cash flows of Parent, CF Industries, the Subsidiary Guarantors or the Non-Guarantors 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. As of June 30, 2018, two of our consolidated entities have made elections to be taxed as partnerships for U.S. federal income tax purposes and are included in the non-guarantor column. Due to the partnership tax treatment, these subsidiaries do not record taxes on their financial statements. The tax provision pertaining to the income of these partnerships, plus applicable deferred tax balances are reflected on the financial statements of the parent company owner that is included in the subsidiary guarantors column in the following financial information. Liabilities related to benefit plan obligations are reflected on the legal entity that funds the obligation, while the benefit plan expense is included on the legal entity to which the employee provides services.

New Accounting Standards (Policies)

Accounting Policies [Abstract]

Recently Adopted Pronouncements

Recently Adopted Pronouncements

On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments. Additionally, the costs to obtain and fulfill a contract, including assets to be recognized, are to be capitalized and such capitalized costs should be disclosed. In 2016, the Financial Accounting Standards Board (FASB) issued additional ASUs that enhanced the operability of the principal versus agent guidance in ASU No. 2014-09 by clarifying that an entity should consider the nature of each good or service promised to a customer at the individual good or service level, clarified that ASU No. 2014-09 should not be applied to immaterial performance obligations, and enhanced the guidance around the treatment of shipping costs incurred to fulfill performance obligations. Our adoption of this ASU, utilizing the modified retrospective approach on contracts that were not completed as of January 1, 2018, resulted in a reduction to opening retained earnings of $1 million related to the cumulative difference between ASC Topic 605 and ASC Topic 606. See Note 3—Revenue Recognition for additional information.

On January 1, 2018, we adopted ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities, which changes the income statement impact of equity investments held by an entity. The amendments require the unrealized gains or unrealized losses of equity instruments measured at fair value to be recognized in net income. Our adoption of this ASU resulted in an increase to opening retained earnings of $1 million representing the cumulative effect of unrealized gains from equity securities from accumulated other comprehensive income (loss).

On January 1, 2018, we adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash - a consensus of the FASB Emerging Issues Task Force, which requires that the statement of cash flows include amounts described as restricted cash and restricted cash equivalents as part of cash and cash equivalents when reconciling the beginning and ending period total amounts. Upon adoption of this ASU, $1 million of withdrawals from restricted cash funds previously reflected as cash provided by investing activities for the six months ended June 30, 2017, and our restricted cash of $5 million and $4 million as of December 31, 2016 and June 30, 2017, respectively, were reclassified to be included within the reconciliation of beginning and ending cash, cash equivalents and restricted cash balances on our consolidated statement of cash flows.

On January 1, 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changed the presentation of net benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Only service cost can be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net benefit cost must be presented separately outside of operating income. Additionally, only service costs may be capitalized on the balance sheet. Our adoption of this ASU was applied retrospectively for the income statement classification requirements and prospectively for the capitalization guidance, which resulted in $1 million and $2 million of net benefit cost previously recognized in cost of sales for the three and six months ended June 30, 2017, respectively, to be reclassified to other non-operating on our consolidated statements of operations.

On January 1, 2018, we adopted ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Our adoption of this ASU had no impact on our consolidated financial statements.

Recently Issued Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in ASC Topic 840, Leases. This ASU will require lessees to recognize the rights and obligations resulting from virtually all leases (other than leases that meet the definition of a short-term lease) on their balance sheets as right-of-use assets with corresponding lease liabilities. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of income and expense recognized and expected to be recognized from existing contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and required the modified retrospective method of adoption. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides the option to adopt ASU No. 2016-02 retrospectively for each prior period presented or as of the adoption date with a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. While we are continuing to evaluate the impact of the adoption of these ASUs on our consolidated financial statements, we currently believe the most significant change relates to the recognition of the right-of-use assets and lease liabilities on our balance sheet for operating leases for certain property and equipment, including transportation equipment utilized for the distribution of our products.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships in order to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and should be applied to existing hedging relationships as of the date of adoption. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and for interim periods therein. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

Revenue Recognition

In situations where we have agreed to arrange delivery of the product to the customer’s intended destination and control of the product transfers upon loading of our product onto transportation equipment, we have elected to account for any freight income associated with the delivery of these products as freight revenue, consistent with our treatment of this income prior to the adoption of ASC 606, since this activity fulfills our obligation to transfer the product to the customer.
