NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
1.   Background and Basis of Presentation
Our mission is to provide clean energy to feed and fuel the world sustainably. With our employees focused on safe and reliable operations, environmental stewardship, and disciplined capital and corporate management, we are on a path to decarbonize our ammonia production network – the world’s largest – to enable green and blue hydrogen and nitrogen products for energy, fertilizer, emissions abatement and other industrial activities. Our nitrogen manufacturing complexes in the United States, Canada and the United Kingdom, an extensive storage, transportation and distribution network in North America, and logistics capabilities enabling a global reach underpin our strategy to leverage our unique capabilities to accelerate the world’s transition to clean energy. Our principal customers are cooperatives, independent fertilizer distributors, traders, wholesalers and industrial users. Our core product is anhydrous ammonia (ammonia), which contains 82% nitrogen and 18% hydrogen. Our nitrogen products that are upgraded from ammonia are 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.
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, 2022, 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 Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on February 23, 2023. The preparation of the unaudited interim consolidated financial statements requires us to make use of estimates and assumptions that may significantly affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the unaudited interim consolidated financial statements and the reported revenues and expenses for the periods presented. Such estimates and assumptions are used for, but are not limited to, net realizable value of inventories, environmental remediation liabilities, environmental and litigation contingencies, plant closure and asset retirement obligations, the cost of emission credits required to meet environmental regulations, the cost of customer incentives, useful lives of property and identifiable intangible assets, the evaluation of potential impairments of property, investments, identifiable intangible assets and goodwill, income tax reserves and the assessment of the realizability of deferred tax assets, the determination of the funded status and annual expense of defined benefit pension and other postretirement plans and the valuation of stock-based compensation awards granted to employees.

2.   Revenue Recognition
We track our revenue by product and by geography. See Note 15—Segment Disclosures for the revenue of each of our reportable segments, 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, 2023 and 2022:

As of June 30, 2023 and December 31, 2022, we had $9 million and $229 million, respectively, in customer advances on our consolidated balance sheets. During the six months ended June 30, 2023 and 2022, substantially all of the customer advances at the beginning of each respective period were recognized as revenue.
We offer cash incentives to certain customers generally based on the volume of their purchases over the fertilizer year ending June 30. Our cash incentives do not provide an option to the customer for additional product. The balances of customer incentives accrued as of June 30, 2023 and December 31, 2022 were not material.
We have certain customer contracts with performance obligations under which, 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, the amount of which payment may vary based upon the terms and conditions of the applicable contract. As of June 30, 2023, 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 were approximately $845 million. We expect to recognize approximately 27% of these performance obligations as revenue in the remainder of 2023, approximately 36% as revenue during 2024-2026, approximately 17% as revenue during 2027-2029, and the remainder thereafter. Subject to the terms and conditions of the applicable contracts, if the customers do not satisfy their purchase obligations under such contracts, the minimum amount that they would be required to pay to us under such contracts, in the aggregate, was approximately $255 million as of June 30, 2023. Other than the performance obligations described above, we expect that any performance obligations under our customer contracts that were unfulfilled or partially fulfilled at December 31, 2022 will be satisfied in 2023.

Diluted earnings per common share is calculated using weighted-average common shares outstanding, including the dilutive effect of stock-based awards as determined under the treasury stock method. In the computation of diluted earnings per common share, potentially dilutive stock-based awards are excluded if the effect of their inclusion is anti-dilutive. Shares for anti-dilutive stock-based awards not included in the computation of diluted earnings per common share were zero in both the three and six months ended June 30, 2023 and the three and six months ended June 30, 2022.

5.   United Kingdom Operations Restructuring
In the second quarter of 2022, we approved and announced our proposed plan to restructure our U.K. operations, including the planned permanent closure of the Ince facility, which had been idled since September 2021, and optimization of the remaining manufacturing operations at our Billingham facility. Pursuant to our proposed plan to restructure our U.K. operations and dispose of the Ince facility assets before we originally intended, we concluded that an evaluation of our long-lived assets and an impairment test was required. Our assessment then identified the U.K. asset groups as U.K. Ammonia, U.K. AN and U.K. Other, comprising our ongoing U.K. operations, and Ince, U.K. In response to this impairment indicator, we compared the undiscounted cash flows expected to result from the use and eventual disposition of the Ince, U.K. asset group to its carrying amount and concluded the carrying amount was not recoverable and should be adjusted to its fair value. As a result, in the second quarter of 2022, we recorded total charges of $162 million related to the Ince facility as follows:
asset impairment charges of $152 million consisting of the following:
an impairment charge of $135 million related to property, plant and equipment that is planned for abandonment at the Ince facility, including a liability of approximately $9 million for the costs of certain asset retirement activities related to the Ince site;
an intangible asset impairment charge of $8 million related to trade names; and

CF INDUSTRIES HOLDINGS, INC.
an impairment charge of $9 million related to the write-down of spare parts and certain raw materials at the Ince facility;
and
a charge for post-employment benefits totaling $10 million, which is included in the U.K. operations restructuring line item in our consolidated statements of operations, related to contractual and statutory obligations due to employees whose employment would be terminated in the proposed plan.
In August 2022, the final restructuring plan was approved, and decommissioning activities at our Ince facility were initiated. As of June 30, 2023, the decommissioning of our Ince facility and other approved restructuring actions have been completed.

Depreciation and amortization related to property, plant and equipment was $218 million and $422 million for the three and six months ended June 30, 2023, respectively, and $219 million and $424 million for the three and six months ended June 30, 2022, respectively.
Plant turnarounds—Scheduled inspections, replacements and overhauls of plant machinery and equipment at our continuous process manufacturing facilities during a full plant shutdown are referred to as plant turnarounds. The expenditures related to turnarounds are capitalized in property, plant and equipment when incurred.
Scheduled replacements and overhauls of plant machinery and equipment during a plant turnaround include the dismantling, repair or replacement and installation of various components including piping, valves, motors, turbines, pumps, compressors and heat exchangers and the replacement of catalysts when a full plant shutdown occurs. Scheduled inspections, including required safety inspections which entail the disassembly of various components such as steam boilers, pressure vessels and other equipment requiring safety certifications, are also conducted during full plant shutdowns. Internal employee costs and overhead amounts are not considered turnaround costs and are not capitalized.

7.   Equity Method Investment
We have a 50% ownership interest in Point Lisas Nitrogen Limited (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, 2023, the total carrying value of our equity method investment in PLNL was $72 million, $32 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 10 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 $36 million and $95 million for the three and six months ended June 30, 2023, respectively, and $77 million and $151 million for the three and six months ended June 30, 2022, 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. As of June 30, 2023 and December 31, 2022, 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.

CF INDUSTRIES HOLDINGS, INC.
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, and changes in fair value are reported in other comprehensive income. Changes in the fair value of available-for-sale equity securities in the trust assets are recognized through earnings.
Derivative Instruments
The derivative instruments that we use are primarily natural gas fixed price swaps, basis swaps and options traded in the over-the-counter markets with multi-national 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 a NYMEX futures price index. 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 12—Derivative Financial Instruments for additional information.
Financial Instruments

Fair ValueCarrying
Amount
Fair Value
 (in millions)
Long-term debt$2,967 $2,767 $2,965 $2,764 
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 any 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.

9.   Income Taxes
For the three months ended June 30, 2023, we recorded an income tax provision of $134 million on pre-tax income of $740 million, or an effective tax rate of 18.2%, compared to an income tax provision of $357 million on pre-tax income of $1.70 billion, or an effective tax rate of 21.1%, for the three months ended June 30, 2022.
For the six months ended June 30, 2023, we recorded an income tax provision of $303 million on pre-tax income of $1.56 billion, or an effective tax rate of 19.5%, compared to an income tax provision of $758 million on pre-tax income of $3.15 billion, or an effective tax rate of 24.1%, for the six months ended June 30, 2022.
Our effective tax rate is impacted by earnings attributable to the noncontrolling interest in CF Industries Nitrogen, LLC (CFN), as our consolidated income tax provision does not include a tax provision on the earnings attributable to the noncontrolling interest. Our effective tax rate for the three months ended June 30, 2023 of 18.2%, which is based on pre-tax income of $740 million, including $79 million of earnings attributable to the noncontrolling interest, would be 2.1 percentage points higher if based on pre-tax income exclusive of the $79 million of earnings attributable to the noncontrolling interest. Our effective tax rate for the three months ended June 30, 2022 of 21.1%, which is based on pre-tax income of $1.70 billion, including $174 million of earnings attributable to the noncontrolling interest, would be 2.4 percentage points higher if based on pre-tax income exclusive of the $174 million of earnings attributable to the noncontrolling interest.
Our effective tax rate for the six months ended June 30, 2023 of 19.5%, which is based on pre-tax income of $1.56 billion, including $169 million of earnings attributable to the noncontrolling interest, would be 2.3 percentage points higher if based on pre-tax income exclusive of the $169 million of earnings attributable to the noncontrolling interest. Our effective tax rate for the six months ended June 30, 2022 of 24.1%, which is based on pre-tax income of $3.15 billion, including $342 million of earnings attributable to the noncontrolling interest, would be 2.9 percentage points higher if based on pre-tax income exclusive of the $342 million of earnings attributable to the noncontrolling interest.
In addition, for the six months ended June 30, 2022, our income tax provision includes $22 million of income tax benefit due to share-based compensation activity and $78 million of income tax provision related to the Canada Revenue Agency Competent Authority Matter, as discussed below.
Canada Revenue Agency Competent Authority Matter
In 2016, the Canada Revenue Agency (CRA) and Alberta Tax and Revenue Administration (Alberta TRA) issued Notices of Reassessment for tax years 2006 through 2009 to one of our Canadian affiliates asserting a disallowance of certain patronage deductions. We filed Notices of Objection with respect to the Notices of Reassessment with the CRA and Alberta TRA and posted letters of credit in lieu of paying the additional tax liability assessed. The letters of credit served as security until the matter was resolved, as discussed below. In 2018, the matter, including the related transfer pricing topic regarding the allocation of profits between Canada and the United States, was accepted for consideration under the bilateral settlement provisions of the U.S.-Canada tax treaty (the Treaty) by the United States and Canadian competent authorities, and included tax years 2006 through 2011. In the second quarter of 2021, the Company submitted the transfer pricing aspect of the matter into the arbitration process under the terms of the Treaty.
In February 2022, we were informed that a decision was reached by the arbitration panel for tax years 2006 through 2011. In March 2022, we received further details of the results of the arbitration proceedings and the settlement provisions between the United States and Canadian competent authorities, and we accepted the decision of the arbitration panel. Under the terms of the arbitration decision, additional income for tax years 2006 through 2011 was subject to tax in Canada, resulting in our having additional Canadian tax liability for those tax years.
In the six months ended June 30, 2022, as a result of the impact of these events on our Canadian and U.S. federal and state income taxes, we recognized an income tax provision of $78 million, reflecting the net impact of $129 million of accrued income taxes payable to Canada for tax years 2006 through 2011, partially offset by net income tax receivables of approximately $51 million in the United States, and we accrued net interest of $104 million, primarily reflecting the impact of estimated interest payable to Canada. Of the $78 million of income tax provision and $104 million of net interest expense recognized in the six months ended June 30, 2022, $2 million of income tax provision and $5 million of net interest expense was recognized in the three months ended June 30, 2022.
In the second half of 2022, this tax liability and the related interest were assessed and paid, resulting in total payments of $224 million, which also reflect the impact of changes in foreign currency exchange rates. As a result, the letters of credit we had posted in lieu of paying the additional tax liability assessed by the Notices of Reassessment were cancelled. Due primarily to the availability of additional foreign tax credits to offset in part the increased Canadian tax referenced above, the Company has filed amended tax returns in the United States to request a refund of taxes paid.

Transfer pricing positions
As a result of the outcome of the arbitration decision discussed above, we also evaluated our transfer pricing positions between Canada and the United States for open years 2012 and after. Based on this evaluation, for the six months ended June 30, 2022, we recorded the following:
liabilities for unrecognized tax benefits of approximately $314 million, with a corresponding income tax provision, and accrued interest of approximately $116 million related to the liabilities for unrecognized tax benefits, and
noncurrent income tax receivables of approximately $359 million, with a corresponding income tax benefit, and accrued interest income of approximately $30 million related to the noncurrent income tax receivables.
In the six months ended June 30, 2022, the impact on our consolidated statement of operations of the amounts recorded as a result of this evaluation of transfer pricing positions, including $26 million of net deferred income tax provision for other transfer pricing tax effects, was $19 million of income tax benefit and $86 million of net interest expense before tax ($93 million after tax). Of the $19 million of income tax benefit and $86 million of net interest expense recognized in the six months ended June 30, 2022, $21 million of income tax benefit and $23 million of net interest expense ($24 million after tax) was recognized in the three months ended June 30, 2022.

10.   Financing Agreements
Revolving Credit Agreement
We have a senior unsecured revolving credit agreement (the Revolving Credit Agreement), which provides for a revolving credit facility of up to $750 million with a maturity of December 5, 2024. 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, capital expenditures, acquisitions, share repurchases and other general corporate purposes.
Borrowings under the Revolving Credit Agreement may be denominated in U.S. dollars, Canadian dollars, euros and British pounds, and bear interest at a per annum rate equal to, at our option, an applicable adjusted term Secured Overnight Financing Rate or base rate plus, in either case, a specified margin. We 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.
As of June 30, 2023, we had unused borrowing capacity under the Revolving Credit Agreement of $750 million and no outstanding letters of credit under the Revolving Credit Agreement. There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2023 or December 31, 2022, or during the six months ended June 30, 2023.
The Revolving Credit Agreement contains representations and warranties and affirmative and negative covenants, including financial covenants. As of June 30, 2023, we were in compliance with all covenants under the Revolving Credit Agreement.
Letters of Credit
In addition to the letters of credit that may be issued under the Revolving Credit Agreement, as described above, we have also entered into a bilateral agreement with capacity to issue up to $350 million of letters of credit. As of June 30, 2023, approximately $205 million of letters of credit were outstanding under this agreement.

12.   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 products. From time to time, we may also use derivative financial instruments to reduce our exposure to changes in foreign currency exchange rates. The derivatives that we use to reduce our exposure to changes in prices for natural gas are primarily natural gas fixed price swaps, basis swaps and options traded in the over-the-counter 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, 2023, we had natural gas derivative contracts covering certain periods through March 2024.
As of June 30, 2023, our open natural gas derivative contracts consisted of natural gas fixed price swaps, basis swaps and options for 43.8 million MMBtus of natural gas. As of December 31, 2022, we had open natural gas derivative contracts consisting of natural gas fixed price swaps, basis swaps and options for 66.3 million MMBtus of natural gas. For the six months ended June 30, 2023, we used derivatives to cover approximately 36% of our natural gas consumption.

Most of our International Swaps and Derivatives Association (ISDA) agreements contain credit-risk-related contingent features such as cross default provisions. In the event of certain defaults or termination events, our counterparties may request early termination and net settlement of certain derivative trades or, under certain ISDA agreements, may require us to collateralize derivatives in a net liability position. As of June 30, 2023 and December 31, 2022, the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was zero and $73 million, respectively, which also approximates the fair value of the assets that may be needed to settle the obligations if the credit-risk-related contingent features were triggered at the reporting dates. 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. As of June 30, 2023 and December 31, 2022, we had no cash collateral on deposit with counterparties for derivative contracts.

13.   Noncontrolling Interest
We have a strategic venture with CHS Inc. (CHS) under which CHS owns an equity interest in CFN, a subsidiary of CF Holdings, which represents approximately 11% of the membership interests of CFN. We own the remaining membership interests. 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, any member contributions made to CFN and withdrawals 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 interest in our consolidated financial statements.
A reconciliation of the beginning and ending balances of noncontrolling interest and distributions payable to noncontrolling interest in our consolidated balance sheets is provided below.

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

On July 31, 2023, the CFN Board of Managers approved semi-annual distribution payments for the distribution period ended June 30, 2023 in accordance with CFN’s limited liability company agreement. On July 31, 2023, CFN distributed $204 million to CHS for the distribution period ended June 30, 2023.

14.   Stockholders’ Equity
Common Stock
On November 3, 2021, our Board of Directors (the Board) authorized the repurchase of up to $1.5 billion of CF Holdings common stock through December 31, 2024 (the 2021 Share Repurchase Program). On November 2, 2022, the Board authorized the repurchase of up to $3 billion of CF Holdings common stock commencing upon completion of the 2021 Share Repurchase Program and effective through December 31, 2025 (the 2022 Share Repurchase Program). Repurchases under these programs may be made from time to time in the open market, through privately negotiated transactions, through block transactions or otherwise. The manner, timing and amount of repurchases will be determined by our management based on the evaluation of market conditions, stock price, and other factors.

Overview of CF Holdings
Our Company
Our mission is to provide clean energy to feed and fuel the world sustainably. With our employees focused on safe and reliable operations, environmental stewardship, and disciplined capital and corporate management, we are on a path to decarbonize our ammonia production network – the world’s largest – to enable green and blue hydrogen and nitrogen products for energy, fertilizer, emissions abatement and other industrial activities. Our nitrogen manufacturing complexes in the United States, Canada and the United Kingdom, an extensive storage, transportation and distribution network in North America, and logistics capabilities enabling a global reach underpin our strategy to leverage our unique capabilities to accelerate the world’s transition to clean energy. Our principal customers are cooperatives, independent fertilizer distributors, traders, wholesalers and industrial users. Our core product is anhydrous ammonia (ammonia), which contains 82% nitrogen and 18% hydrogen. Our nitrogen products that are upgraded from ammonia are 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.
Our principal assets as of June 30, 2023 include:
five U.S. nitrogen manufacturing facilities located in Donaldsonville, Louisiana (the largest nitrogen complex in the world); Sergeant Bluff, Iowa (our Port Neal complex); Yazoo City, Mississippi; Claremore, Oklahoma (our Verdigris complex); and Woodward, Oklahoma. These facilities are wholly owned directly or indirectly by CF Industries Nitrogen, LLC (CFN), of which we own approximately 89% and CHS Inc. (CHS) owns the remainder (see Note 13—Noncontrolling Interest for additional information on our strategic venture with CHS);
two Canadian nitrogen manufacturing facilities located in Medicine Hat, Alberta (the largest nitrogen complex in Canada) and Courtright, Ontario;
a United Kingdom nitrogen manufacturing facility located in Billingham;
an extensive system of terminals and associated transportation equipment located primarily in the Midwestern United States; and

a 50% interest in Point Lisas Nitrogen Limited (PLNL), an ammonia production joint venture located in the Republic of Trinidad and Tobago (Trinidad) that we account for under the equity method.
Our Commitment to a Clean Energy Economy
We are taking significant steps to support a global hydrogen and clean fuel economy, through the production of green and blue ammonia. Since ammonia is one of the most efficient ways to transport and store hydrogen and is also a fuel in its own right, we believe that the Company, as the world’s largest producer of ammonia with an unparalleled manufacturing and distribution network and deep technical expertise, is uniquely positioned to fulfill anticipated demand for hydrogen and ammonia from green and blue sources. Our approach includes green ammonia production, which refers to ammonia produced through a carbon-free process, and blue ammonia production, which relates to ammonia produced by conventional processes but with CO2 byproduct removed through carbon capture and sequestration (CCS).
In April 2021, we signed an engineering and procurement contract with thyssenkrupp to supply a 20 MW alkaline water electrolysis plant to produce green hydrogen at our Donaldsonville complex. Construction and installation, which is being managed by us, is expected to finish in late 2023, with an estimated total cost of approximately $100 million. We will integrate the green hydrogen generated by the electrolysis plant into existing ammonia synthesis loops to enable the production of approximately 20,000 tons per year of green ammonia. We believe that the Donaldsonville green ammonia project will be the largest of its kind in North America at the time of its startup.
In July 2022, we and Mitsui & Co., Ltd. (Mitsui) signed a joint development agreement for the companies’ proposed plans to construct an export-oriented blue ammonia facility. We and Mitsui continue to progress a front-end engineering and design (FEED) study for the project and expect to make a final investment decision on the proposed facility later in 2023. Should the companies agree to move forward, the ammonia facility would be constructed at our new Blue Point complex. We own the land for the complex, which is located on the west bank of the Mississippi river in Ascension Parish, Louisiana. Construction and commissioning of a new world-scale ammonia plant typically takes approximately four years from the time construction begins.
In the first quarter of 2023, we signed a memorandum of understanding (MOU) with JERA Co., Inc. (JERA), Japan’s largest energy generator, regarding the long-term supply of up to 500,000 tonnes per year of clean ammonia beginning in 2027. The execution of the MOU was the result of a supplier comparison and evaluation process for the procurement of clean ammonia that JERA initiated in February 2022 for the world’s first commercial scale ammonia co-firing operations that JERA is developing. The MOU establishes a framework for JERA and us to assess how we would best supply JERA with clean ammonia, which will be required to be produced with at least 60% lower carbon emissions than conventionally produced ammonia, under a long-term offtake agreement. We and JERA expect to evaluate a range of potential supply options, including JERA making an equity investment with us to develop a clean ammonia facility in Louisiana and a supplementary long-term offtake agreement.
In the first quarter of 2023, we signed an MOU with LOTTE CHEMICAL Corporation (LOTTE), a global chemicals company in South Korea. The MOU will guide LOTTE and us in a joint exploration of the development of clean ammonia production in the United States, in addition to the quantification of expected clean ammonia demand in South Korea and long-term clean ammonia offtake volumes into South Korea.
We are also pursuing opportunities to produce blue ammonia from our existing ammonia production network. We are currently executing a project with an estimated cost of $200 million to construct a CO2 dehydration and compression facility at our Donaldsonville complex to enable the transport and permanent sequestration of the ammonia process CO2 byproduct. Engineering activities for the construction of the dehydration and compression unit continue to advance, procurement of major equipment for the facility is in progress, and fabrication of the CO2 compressors has begun. In October 2022, we announced that we had entered into a definitive CO2 offtake agreement with ExxonMobil to transport and permanently sequester CO2 from Donaldsonville. Once the dehydration and compression unit is in service and sequestration is initiated, we expect that the Donaldsonville complex will have the capacity to dehydrate and compress up to 2 million tons per year of process CO2, enabling the production of blue ammonia. Start-up for the project is planned for 2025. Under current regulations, the project would be expected to qualify for tax credits under Section 45Q of the Internal Revenue Code, which provides a credit per tonne of CO2 sequestered.
Agreement to Purchase Ammonia Production Facility
On March 20, 2023, we entered into an asset purchase agreement with Dyno Nobel Louisiana Ammonia, LLC (DNLA), a U.S. subsidiary of Australian-based Incitec Pivot Limited (IPL), and IPL. Under the terms of the agreement, we will purchase DNLA’s ammonia production complex located in Waggaman, Louisiana for a purchase price of $1.675 billion, subject to adjustment. The facility has a nameplate capacity of 880,000 tons of ammonia annually. The parties will allocate $425 million

of the purchase price to a long-term ammonia offtake agreement providing for us to supply up to 200,000 tons of ammonia per year to IPL’s Dyno Nobel, Inc. subsidiary. We expect to fund the balance of the purchase price, representing the $1.675 billion purchase price, as adjusted, less $425 million, with cash on hand.
The consummation of the transaction is subject to the satisfaction or waiver of customary conditions, including, among others, the expiration or early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The agreement includes certain customary termination rights, including the right of either party to terminate the agreement if the closing has not occurred by March 20, 2025. We have agreed to pay a termination fee of $75 million if the agreement is terminated in certain circumstances and certain regulatory approvals are not obtained.
Market Conditions
Geopolitical Environment
Changes in the geopolitical environment can have significant effects on our financial results. Russia’s invasion of Ukraine in February 2022, and the resulting war between Russia and Ukraine, disrupted global markets for certain commodities, including natural gas, nitrogen fertilizers and certain commodity grains and oilseeds, leading to production curtailments, export reductions and logistical complications involving these commodities. Additionally, energy, financial and transportation sanctions were announced by U.S., Canadian, European and other governments against Russia in response to the war. During 2022 and 2023, market participants have continued to adjust trade flows and manufacturers have continued to adjust production levels in response to changing conditions resulting from these factors. As of the date of filing of this report, nitrogen fertilizers have largely been explicitly exempted from sanctions against Russia by the United States and certain other governments, and as a result, there has been an increase in Russian fertilizer exports into the United States and other parts of the world.
As further described below, natural gas is the principal raw material used to produce our nitrogen products. Natural gas is a globally traded commodity that experiences price fluctuations based on supply and demand balances and has been impacted by geopolitical events relating to the war between Russia and Ukraine. European energy markets, which have historically sourced a substantial portion of their natural gas from Russia, were disrupted by Russia’s invasion of Ukraine and the subsequent reduction of Russian natural gas supply to Europe during 2022. This led to further increases in natural gas prices and natural gas price volatility, which in turn led to disruptions in manufacturing and distribution activities at other nitrogen manufacturers and suppliers in our industry, resulting in changes in nitrogen product trade flows and reductions in global fertilizer supply. In September 2022, in response to the high prices for natural gas in the United Kingdom, we idled ammonia production at our Billingham complex and since that time have been importing ammonia from one of our North American manufacturing facilities or from purchases in the open market for upgrade into AN and other nitrogen products at that location.
The geopolitical developments relating to the war in Ukraine also led to some supply chain disruptions for Russian producers of fertilizer, contributing to reduced global nitrogen fertilizer supply. Prior to its February 2022 invasion of Ukraine, Russia in recent years had been a significant supplier of nitrogen fertilizer products to North America and Europe and a leading exporter of nitrogen fertilizer products globally. Furthermore, the subsequent closure of a pipeline historically transporting ammonia from Russia through Ukraine for export has been a large contributor to reduced global exportable ammonia supply. In addition, Russia and Ukraine have been large exporters of commodity grains such as wheat, corn and soybeans. The direct and indirect impacts of the war in Ukraine, and the related uncertainty, resulted in reduced commodity grain supply from Russia and Ukraine, causing increased prices for grains globally. The increase in commodity grain prices in turn supported strong demand for nitrogen fertilizer in 2022. All of these geopolitical developments further contributed to an already tight global supply and demand balance for nitrogen fertilizers. These factors caused changes in global trade flows as both manufacturers and customers reacted to the changing market dynamics. As a result, global nitrogen fertilizer prices remained high and also experienced significant volatility in 2022.
As Russian-sourced natural gas supply declined due to geopolitical factors, European purchasers of natural gas increased imports from the liquified natural gas (LNG) market to build storage levels leading up to the winter 2022/2023 peak demand season. As storage levels of natural gas increased due to the increased LNG imports, in conjunction with a warmer than expected winter in Europe, prices for natural gas first stabilized and then fell during the first half of 2023. As natural gas prices decreased, certain nitrogen producers restarted previously idled production, leading to an increase in global nitrogen production operating rates. The increased global nitrogen product supply availability resulting from the increase in operating rates, in addition to new global production coming on line and an increase in Russian imports of UAN into the United States, resulted in an increase in supply and lower average selling prices in the first half of 2023 compared to average selling prices realized in 2022.

Nitrogen Selling Prices
Our nitrogen products are globally traded commodities with selling prices that fluctuate in response to global market conditions, changes in supply and demand, and other cost factors including domestic and local conditions. Intense global competition—reflected in import volumes and prices—strongly influences delivered prices for nitrogen fertilizers. In general, the prevailing global prices for nitrogen products must be at a level to incent the high cost marginal producer to produce product at a breakeven or above price, or else they would cease production and leave a portion of global demand unsatisfied.
In the second quarter of 2023, the average selling price for our products was $359 per ton, a decrease of 49% compared to $701 per ton in the second quarter of 2022, reflecting lower average selling prices across all our segments, which drove a decrease in net sales of approximately $1.66 billion for the second quarter of 2023 compared to the second quarter of 2022. The decrease in average selling prices reflects the impact of an increase in global supply availability as lower global energy costs drove higher global operating rates. In addition, higher average selling prices in 2022 were driven in part by the geopolitical environment experienced in 2022, as described above. In the six months ended June 30, 2023, the average selling price for our products was $400 per ton, or 39% lower compared to $661 per ton in the six months ended June 30, 2022. This resulted in a decrease in net sales of approximately $2.47 billion for the six months ended June 30, 2023 compared to the six months ended June 30, 2022.
Natural Gas
Natural gas is the principal raw material used to produce our nitrogen products. Natural gas is both a chemical feedstock and a fuel used to produce nitrogen products. Natural gas is a significant cost component of our manufactured nitrogen products, representing approximately 50% of our production costs in both the first six months of 2023 and in the year ended December 31, 2022.
The following table presents the average daily market price of natural gas at the Henry Hub, the most heavily-traded natural gas pricing point in North America:
 Three Months Ended June 30,Six Months Ended June 30,
202320222023 v. 202220232022
2023 v. 2022
Average daily market price of natural gas Henry Hub (Louisiana) (per MMBtu)$2.12 $7.40 $(5.28)(71)%$2.40 $6.01 $(3.61)(60)%
Most of our nitrogen manufacturing facilities are located in the United States and Canada. As a result, the price of natural gas in North America directly impacts a substantial portion of our operating expenses. North American natural gas prices were lower on average during the first six months of 2023 than during the first six months of 2022. Warmer-than-normal temperatures in the first quarter of 2023 drove lower heating demand for natural gas, while North American supply remained strong, as there were few weather-related production disruptions. In addition, although the higher cost for natural gas outside of North America incentivized liquefaction facilities in the United States to export domestic natural gas during the first half of 2023, the ongoing outage at the Freeport LNG facility as well as planned maintenance at several other LNG facilities limited total gas exports, supporting domestic supply. As a result, North America entered the second quarter of 2023 with above-average volumes of gas in storage and was able to inject at higher-than-average rates, leading to end-of-quarter storage levels that were 25% higher than one year ago and 15% higher than the five-year average. For July 2023, the average daily market price of natural gas at the Henry Hub was $2.54 per MMBtu.
Our Billingham U.K. nitrogen manufacturing facility has been subject to fluctuations associated with the price of natural gas in Europe. Russia’s invasion of Ukraine in February 2022 disrupted European energy markets and threatened security of supply, driving natural gas prices in Europe upward to unprecedented levels. In the three and six months ended June 30, 2022, the average daily market price of natural gas at the National Balancing Point (NBP), the major trading point for natural gas in the United Kingdom, was $16.00 per MMBtu and $23.06 per MMBtu, respectively. In September 2022, as a result of extremely high and volatile natural gas prices and the lack of a corresponding increase in global nitrogen product market prices, we idled ammonia production at our Billingham complex. Since that time, we have imported ammonia for upgrade into AN and other nitrogen products at that location.
In the second quarter of 2023, our cost of natural gas used for production, which includes the impact of realized natural gas derivatives, decreased 61% to $2.75 per MMBtu from $7.05 per MMBtu in the second quarter of 2022. This decrease in natural gas costs resulted in an increase in gross margin of approximately $360 million compared to the second quarter of 2022. In the first half of 2023, our cost of natural gas used for production, which includes the impact of realized natural gas derivatives, decreased 33% to $4.56 per MMBtu from $6.79 per MMBtu in the first half of 2022. This decrease in natural gas costs resulted in an increase in gross margin of approximately $332 million compared to the first half of 2022.

Financial Executive Summary
We reported net earnings attributable to common stockholders of $527 million for the three months ended June 30, 2023 compared to $1.17 billion for the three months ended June 30, 2022, a decrease in net earnings of $638 million. The decrease in net earnings for the three months ended June 30, 2023 compared to the three months ended June 30, 2022 reflects a decrease of $1.19 billion in gross margin to $804 million for the three months ended June 30, 2023. The decrease in gross margin was due primarily to a 49% decrease in average selling prices to $359 per ton in the second quarter of 2023 from $701 per ton in the second quarter of 2022, which decreased gross margin by $1.66 billion. The impact of lower selling prices was partially offset by lower natural gas costs, which increased gross margin by approximately $360 million. In addition, lower gross margin was partially offset by pre-tax impairment and restructuring charges related to our U.K. operations of $162 million in the second quarter of 2022 that did not recur in the second quarter of 2023 and a decrease in the income tax provision of $223 million due primarily to lower earnings in the second quarter of 2023.
Diluted net earnings per share attributable to common stockholders decreased $2.88 per share, to $2.70 per share, in the second quarter of 2023 compared to $5.58 per share in the second quarter of 2022 due primarily to lower net earnings, partially offset by lower weighted-average common shares outstanding as a result of shares repurchased under our share repurchase programs.
Items Affecting Comparability of Results
For the three months ended June 30, 2023 and 2022, we reported net earnings attributable to common stockholders of $527 million and $1.17 billion, respectively. For the six months ended June 30, 2023 and 2022, we reported net earnings attributable to common stockholders of $1.09 billion and $2.05 billion, respectively. In addition to the impact of market conditions discussed above, certain items affected the comparability of our financial results for the three and six months ended June 30, 2023 and 2022.

Unrealized net mark-to-market gain on natural gas derivatives
Natural gas is the largest and most volatile single component of the manufacturing cost for our nitrogen-based products. At certain times, we have managed 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, basis swaps and 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 are reflected in cost of sales in our consolidated statements of operations. In the three months ended June 30, 2022, we recognized an unrealized net mark-to-market gain of $17 million. In the six months ended June 30, 2023 and 2022, we recognized unrealized net mark-to-market gains of $72 million and $50 million, respectively.
(Gain) loss on foreign currency transactions, including intercompany loans
In the six months ended June 30, 2023 and 2022, we recognized a (gain) loss on foreign currency transactions of $(2) million and $11 million, respectively. Gains and losses on foreign currency transactions consist of foreign currency exchange rate impacts on foreign currency denominated transactions, including the impact of changes in foreign currency exchange rates on intercompany loans that were not permanently invested.
U.K. operations
In the second quarter of 2022, we approved and announced our proposed plan to restructure our U.K. operations, including the planned permanent closure of the Ince facility, which had been idled since September 2021, and optimization of the remaining manufacturing operations at our Billingham facility. As a result, we recorded total charges of $162 million related to the Ince facility as follows:
asset impairment charges of $152 million consisting of the following:
an impairment charge of $135 million related to property, plant and equipment that is planned for abandonment at the Ince facility, including a liability of approximately $9 million for the costs of certain asset retirement activities related to the Ince site;
an intangible asset impairment charge of $8 million related to trade names; and
an impairment charge of $9 million related to the write-down of spare parts and certain raw materials at the Ince facility;
and
a charge for post-employment benefits totaling $10 million, which is included in the U.K. operations restructuring line item in our consolidated statements of operations, related to contractual and statutory obligations due to employees whose employment would be terminated in the proposed plan.

See Note 5—United Kingdom Operations Restructuring for additional information.

In the six months ended June 30, 2023, we incurred restructuring costs of $2 million related to the permanent closure of our Ince facility.
Transaction costs related to acquisition agreement
On March 20, 2023, we entered into an asset purchase agreement with DNLA and IPL to acquire DNLA’s ammonia production complex located in Waggaman, Louisiana, as described above under “Agreement to Purchase Ammonia Production Facility.” In the three and six months ended June 30, 2023, we incurred $3 million and $16 million, respectively, of transaction costs related to the acquisition agreement.
Canada Revenue Agency Competent Authority Matter
In 2016, the Canada Revenue Agency (CRA) and Alberta Tax and Revenue Administration (Alberta TRA) issued Notices of Reassessment for tax years 2006 through 2009 to one of our Canadian affiliates asserting a disallowance of certain patronage deductions. We filed Notices of Objection with respect to the Notices of Reassessment with the CRA and Alberta TRA and posted letters of credit in lieu of paying the additional tax liability assessed. The letters of credit served as security until the matter was resolved. In 2018, the matter, including the related transfer pricing topic regarding the allocation of profits between

Canada and the United States, was accepted for consideration under the bilateral settlement provisions of the U.S.-Canada tax treaty (the Treaty) by the United States and Canadian competent authorities, and included tax years 2006 through 2011. In the second quarter of 2021, the Company submitted the transfer pricing aspect of the matter into the arbitration process under the terms of the Treaty.
In February 2022, we were informed that a decision was reached by the arbitration panel for tax years 2006 through 2011. In March 2022, we received further details of the results of the arbitration proceedings and the settlement provisions between the United States and Canadian competent authorities, and we accepted the decision of the arbitration panel. Under the terms of the arbitration decision, additional income for tax years 2006 through 2011 was subject to tax in Canada, resulting in our having additional Canadian tax liability for those tax years. See Note 9—Income Taxes for additional information.
In the six months ended June 30, 2022, as a result of the impact of these events on our Canadian and U.S. federal and state income taxes, we recognized an income tax provision of $78 million, reflecting the net impact of $129 million of accrued income taxes payable to Canada for tax years 2006 through 2011, partially offset by net income tax receivables of approximately $51 million in the United States, and we accrued net interest of $104 million, primarily reflecting the impact of estimated interest payable to Canada. Of the $78 million of income tax provision and $104 million of net interest expense recognized in the six months ended June 30, 2022, $2 million of income tax provision and $5 million of net interest expense was recognized in the three months ended June 30, 2022.
Transfer pricing positions
As a result of the outcome of the arbitration decision discussed above, we also evaluated our transfer pricing positions between Canada and the United States for open years 2012 and after. Based on this evaluation, for the six months ended June 30, 2022, we recorded the following:
liabilities for unrecognized tax benefits of approximately $314 million, with a corresponding income tax provision, and accrued interest of approximately $116 million related to the liabilities for unrecognized tax benefits, and
noncurrent income tax receivables of approximately $359 million, with a corresponding income tax benefit, and accrued interest income of approximately $30 million related to the noncurrent income tax receivables.
In the six months ended June 30, 2022, the impact on our consolidated statement of operations of the amounts recorded as a result of this evaluation of transfer pricing positions, including $26 million of net deferred income tax provision for other transfer pricing tax effects, was $19 million of income tax benefit and $86 million of net interest expense before tax ($93 million after tax). Of the $19 million of income tax benefit and $86 million of net interest expense recognized in the six months ended June 30, 2022, $21 million of income tax benefit and $23 million of net interest expense ($24 million after tax) was recognized in the three months ended June 30, 2022.
Loss on debt extinguishment
On April 21, 2022, we redeemed in full all of the $500 million outstanding principal amount of the 3.450% senior notes due June 2023 (the 2023 Notes) in accordance with the optional redemption provisions in the indenture governing the 2023 Notes. The total aggregate redemption price paid in connection with the April 2022 redemption of the 2023 Notes was $513 million, including accrued interest. As a result, we recognized a loss on debt extinguishment of $8 million, consisting primarily of the premium paid on the redemption of the $500 million principal amount of the 2023 Notes prior to their scheduled maturity.

Second Quarter of 2023 Compared to Second Quarter of 2022
Net Sales
Our total net sales decreased $1.61 billion, or 48%, to $1.78 billion in the second quarter of 2023 compared to $3.39 billion in the second quarter of 2022 due primarily to a decrease in average selling prices.
Our average selling price was $359 per ton in the second quarter of 2023, or 49% lower compared to $701 per ton in the second quarter of 2022, due to lower average selling prices across all of our segments. The impact of lower average selling prices was a decrease in net sales of approximately $1.66 billion for the second quarter of 2023 compared to the second quarter of 2022. The decrease in average selling prices reflects the impact of an increase in global supply availability as lower global energy costs drove higher global operating rates.
Our total sales volume of 4.9 million product tons in the second quarter of 2023 was 2% higher compared to 4.8 million product tons in the second quarter of 2022 due primarily to higher sales volume in our UAN segment, partially offset by lower sales volume in our AN segment.
Gross ammonia production for the three and six months ended June 30, 2023 was 2.4 million tons and 4.7 million tons, respectively. We expect gross ammonia production for 2023 will be in a range of 9.0 million to 9.5 million tons as we have a proposed plan to permanently close the ammonia plant at our Billingham, U.K. complex.
Cost of Sales
Our total cost of sales decreased $427 million, or 31%, to $971 million in the second quarter of 2023 from $1.40 billion in the second quarter of 2022. The decrease in our cost of sales was due primarily to lower costs for natural gas, which
30

Table of Contents
CF INDUSTRIES HOLDINGS, INC.
decreased cost of sales by $360 million, including the impact of realized derivatives, and lower costs for ammonia purchased from PLNL, our joint venture in Trinidad. Lower natural gas costs were partially offset by the cost to import ammonia in the second quarter of 2023 for our U.K. operations.

Cost of sales averaged $196 per ton in the second quarter of 2023 compared to $289 per ton in the second quarter of 2022. Our cost of natural gas decreased 61% to $2.75 per MMBtu in the second quarter of 2023 from $7.05 per MMBtu in the second quarter of 2022.
Selling, General and Administrative Expenses
Selling, general and administrative expenses were $71 million in the second quarter of 2023, essentially unchanged from $73 million in the second quarter of 2022.
U.K. Operations
In the three months ended June 30, 2022, we recognized total charges of $162 million consisting of $152 million of asset impairment charges primarily related to property, plant and equipment at our Ince, U.K. facility and $10 million of post-employment benefits related to contractual and statutory obligations. See “Items Affecting Comparability of Results—U.K. operations,” above, for further discussion.
Transaction Costs
On March 20, 2023, we entered into an asset purchase agreement with DNLA and IPL to acquire DNLA’s ammonia production complex located in Waggaman, Louisiana, as described above under “Agreement to Purchase Ammonia Production Facility.” In the three months ended June 30, 2023, we incurred $3 million of transaction costs related to the acquisition agreement.
Equity in Earnings of Operating Affiliate
Equity in earnings of operating affiliate was $7 million in the second quarter of 2023 compared to $28 million in the second quarter of 2022. The decrease was due primarily to a decrease in the operating results of PLNL as a result of lower ammonia selling prices, partially offset by lower natural gas costs.
Interest Expense
Interest expense was $36 million in the second quarter of 2023 compared to $82 million in the second quarter of 2022. The decrease of $46 million was due primarily to $42 million of tax-related interest expense recorded in the second quarter of 2022, including $30 million of interest expense related to income tax matters described under “Items Affecting Comparability of Results—Canada Revenue Agency Competent Authority Matter” and “Items Affecting Comparability of Results—Transfer pricing positions,” above.
Interest Income
Interest income was $40 million in the second quarter of 2023 compared to $8 million in the second quarter of 2022. The increase of $32 million was due primarily to higher interest income on short-term investments, which are included in cash and cash equivalents in our consolidated balance sheet.
Loss on Debt Extinguishment
Loss on debt extinguishment of $8 million in the second quarter of 2022 is described under “Items Affecting Comparability of Results—Loss on debt extinguishment,” above.
Income Taxes
For the three months ended June 30, 2023, we recorded an income tax provision of $134 million on pre-tax income of $740 million, or an effective tax rate of 18.2%, compared to an income tax provision of $357 million on pre-tax income of $1.70 billion, or an effective tax rate of 21.1%, for the three months ended June 30, 2022.
Our effective tax rate is impacted by earnings attributable to the noncontrolling interest in CFN, as our consolidated income tax provision does not include a tax provision on the earnings attributable to the noncontrolling interest. Our effective tax rate for the three months ended June 30, 2023 of 18.2%, which is based on pre-tax income of $740 million, including $79 million of earnings attributable to the noncontrolling interest, would be 2.1 percentage points higher, or 20.3%, if based on pre-tax income exclusive of the earnings attributable to the noncontrolling interest of $79 million. Our effective tax rate for the
31

CF INDUSTRIES HOLDINGS, INC.
three months ended June 30, 2022 of 21.1%, which is based on pre-tax income of $1.70 billion, including $174 million of earnings attributable to the noncontrolling interest, would be 2.4 percentage points higher, or 23.5%, if based on pre-tax income exclusive of the $174 million of earnings attributable to the noncontrolling interest. See Note 13—Noncontrolling Interest for additional information.
Net Earnings Attributable to Noncontrolling Interest
Net earnings attributable to noncontrolling interest decreased $95 million to $79 million in the second quarter of 2023 compared to $174 million in the second quarter of 2022 due to lower earnings of CFN driven by lower average selling prices as described above under “Net Sales.”
Diluted Net Earnings Per Share Attributable to Common Stockholders
Net earnings per share attributable to common stockholders decreased $2.88 to $2.70 per diluted share in the second quarter of 2023 from $5.58 per diluted share in the second quarter of 2022. This decrease was due primarily to a decrease in gross margin, driven by lower average selling prices. The impact of lower selling prices was partially offset by lower natural gas costs, which increased gross margin by approximately $360 million. In addition, lower gross margin was partially offset by pre-tax impairment and restructuring charges related to our U.K. operations of $162 million in the second quarter of 2022 that did not recur in the second quarter of 2023 and a decrease in the income tax provision resulting from lower profitability. Additionally, diluted weighted-average common shares outstanding declined 7% from 208.9 million shares for the three months ended June 30, 2022 to 195.0 million shares for the three months ended June 30, 2023, due primarily to repurchases of common shares under our share repurchase programs.
Six Months Ended June 30, 2023 Compared to Six Months Ended June 30, 2022
Net Sales
Our total net sales decreased $2.47 billion, or 39%, to $3.79 billion in the first six months of 2023 as compared to $6.26 billion in the first six months of 2022 due primarily to a decrease in average selling prices.
Our average selling price was $400 per ton in the first six months of 2023, or 39% lower compared to $661 per ton in the first six months of 2022, due to lower average selling prices across all of our segments, primarily driven by an increase in global supply availability as lower global energy costs drove higher global operating rates. The impact of lower average selling prices was a decrease in net sales of approximately $2.47 billion for the six months ended June 30, 2023 compared to the six months ended June 30, 2022.
Cost of Sales
Our total cost of sales decreased $448 million, or 17%, to $2.12 billion in the first six months of 2023 from $2.57 billion in the first six months of 2022. The decrease in our cost of sales was due primarily to lower costs for natural gas, which decreased cost of sales by $332 million, including the impact of realized derivatives, and lower costs for ammonia purchased from PLNL, our joint venture in Trinidad. Lower natural gas costs were partially offset by the cost to import ammonia in the first six months of 2023 for our U.K. operations.
Cost of sales also includes the impact of a $72 million unrealized net mark-to-market gain on natural gas derivatives in the first six months of 2023 compared to a $50 million gain in the first six months of 2022.
Cost of sales averaged $224 per ton in the first six months of 2023 compared to $271 per ton in the first six months of 2022. Our cost of natural gas decreased 33% to $4.56 per MMBtu in the first six months of 2023 from $6.79 per MMBtu in the first six months of 2022.
Selling, General and Administrative Expenses
Selling, general and administrative expenses increased $8 million to $145 million in the first six months of 2023 as compared to $137 million in the first six months of 2022. The increase was due primarily to higher costs related to certain corporate initiatives, including higher amortization due to our recently implemented enterprise resource planning (ERP) system.
U.K. Operations
In the first six months of 2022, we recognized total charges of $162 million consisting of $152 million of asset impairment charges primarily related to property, plant and equipment at our Ince, U.K. facility and $10 million of post-employment benefits related to contractual and statutory obligations. See “Items Affecting Comparability of Results—U.K. operations,” above, for further discussion.

Transaction Costs
On March 20, 2023, we entered into an asset purchase agreement with DNLA and IPL to acquire DNLA’s ammonia production complex located in Waggaman, Louisiana, as described above under “Agreement to Purchase Ammonia Production Facility.” In the six months ended June 30, 2023, we incurred $16 million of transaction costs related to the acquisition agreement.
Other Operating—Net
Other operating—net was $32 million of income in the first six months of 2023 compared to $8 million of expense in the first six months of 2022. The $32 million of income in the first six months of 2023 consists primarily of gains on the sales of emission credits.
Equity in Earnings of Operating Affiliate
Equity in earnings of operating affiliate was $24 million in the first six months of 2023 compared to $54 million in the first six months of 2022. The decrease was due primarily to a decrease in the operating results of PLNL as a result of lower ammonia selling prices, partially offset by lower natural gas costs.
Interest Expense
Interest expense was $76 million in the first six months of 2023 compared to $323 million in the first six months of 2022. The decrease of $247 million was due primarily to $240 million of tax-related interest expense recorded in the first six months of 2022, including $228 million of interest expense related to income tax matters described under “Items Affecting Comparability of Results—Canada Revenue Agency Competent Authority Matter” and “Items Affecting Comparability of Results—Transfer pricing positions,” above. In addition, the decrease in interest expense was due to lower interest expense on borrowings due to the redemption of $500 million principal amount of the 2023 Notes in April 2022 prior to their scheduled maturity.
Interest Income
Interest income was $70 million in the first six months of 2023 compared to $44 million in the first six months of 2022. The increase of $26 million was due primarily to a $52 million increase in interest income on short-term investments in the first six months of 2023 and interest income recorded in the first six months of 2022 that did not recur in the first six months of 2023, which was related to income tax matters described under “Items Affecting Comparability of Results—Canada Revenue Agency Competent Authority Matter” and “Items Affecting Comparability of Results—Transfer pricing positions,” above.
Loss on Debt Extinguishment
Loss on debt extinguishment of $8 million in the first six months of 2022 is described under “Items Affecting Comparability of Results—Loss on debt extinguishment,” above.
Income Taxes
For the six months ended June 30, 2023, we recorded an income tax provision of $303 million on pre-tax income of $1.56 billion, or an effective tax rate of 19.5%, compared to an income tax provision of $758 million on pre-tax income of $3.15 billion, or an effective tax rate of 24.1%, for the six months ended June 30, 2022.
Our effective tax rate is impacted by earnings attributable to the noncontrolling interest in CFN, as our consolidated income tax provision does not include a tax provision on the earnings attributable to the noncontrolling interest. Our effective tax rate for the six months ended June 30, 2023 of 19.5%, which is based on pre-tax income of $1.56 billion, including $169 million of earnings attributable to the noncontrolling interest, would be 2.3 percentage points higher, or 21.8%, if based on pre-tax income exclusive of the earnings attributable to the noncontrolling interest of $169 million. Our effective tax rate for the six months ended June 30, 2022 of 24.1%, which is based on pre-tax income of $3.15 billion, including $342 million of earnings attributable to the noncontrolling interest, would be 2.9 percentage points higher, or 27.0%, if based on pre-tax income exclusive of the earnings attributable to the noncontrolling interest of $342 million.
In addition, for the six months ended June 30, 2022, our income tax provision includes $22 million of income tax benefit due to share-based compensation activity and $78 million of income tax provision related to the Canada Revenue Agency Competent Authority Matter, which is described above under “Items Affecting Comparability of Results.”

Net Earnings Attributable to Noncontrolling Interest
Net earnings attributable to noncontrolling interest decreased $173 million to $169 million in the first six months of 2023 compared to $342 million in the first six months of 2022 due to lower earnings of CFN driven by lower average selling prices as described above under “Net Sales.”
Diluted Net Earnings Per Share Attributable to Common Stockholders
Net earnings per share attributable to common stockholders decreased $4.23 to $5.55 per diluted share in the first six months of 2023 from $9.78 per diluted share in the first six months of 2022. This decrease was due primarily to a decrease in gross margin, driven by lower average selling prices. Lower gross margin was partially offset by a decrease in interest expense due primarily to interest expense on tax liabilities in the first half of 2022 related to Canadian-U.S. transfer pricing matters that did not recur in the first half of 2023, a decrease in the income tax provision resulting from lower profitability, and pre-tax impairment and restructuring charges related to our U.K. operations of $162 million in the first half of 2022 that did not recur in the first half of 2023. Additionally, diluted weighted-average common shares outstanding declined 6% from 209.4 million shares for the six months ended June 30, 2022 to 195.9 million shares for the six months ended June 30, 2023, due primarily to repurchases of common shares under our share repurchase programs.

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 primarily of selling, general and administrative expenses and other operating—net) and non-operating expenses (consisting primarily of interest and income taxes), are centrally managed and are not included in the measurement of segment profitability reviewed by management.

Second Quarter of 2023 Compared to Second Quarter of 2022
Net Sales.    Net sales in our Ammonia segment decreased by $590 million, or 53%, to $525 million in the second quarter of 2023 from $1.12 billion in the second quarter of 2022 due to a 54% decrease in average selling prices, partially offset by a 2% increase in sales volume. Average selling prices decreased to $499 per ton in the second quarter of 2023 compared to $1,077 per ton in the second quarter of 2022 due primarily to an increase in global supply availability as lower global energy costs drove higher global operating rates. Sales volume was higher due primarily to higher beginning inventory.
Cost of Sales.    Cost of sales in our Ammonia segment averaged $288 per ton in the second quarter of 2023, a 33% decrease from $427 per ton in the second quarter of 2022. The decrease was due primarily to lower realized natural gas costs, including the impact of realized derivatives, and a lower cost per ton for ammonia purchased from PLNL, our joint venture in Trinidad.
Gross Margin.    Gross margin in our Ammonia segment decreased by $451 million to $222 million in the second quarter of 2023 from $673 million in the second quarter of 2022, and our gross margin percentage was 42.3% in the second quarter of 2023 compared to 60.4% in the second quarter of 2022. The decrease in gross margin was due primarily to the following: (i) a 54% decrease in average selling prices, which decreased gross margin by $605 million, (ii) the impact of changes in sales volume and mix, which decreased gross margin by $28 million, and (iii) an $8 million net increase in manufacturing, maintenance and other costs. These factors that decreased gross margin were partially offset by a lower cost per ton for purchased product, which increased gross margin by $109 million, and a decrease in realized natural gas costs, including the impact of realized derivatives, which increased gross margin by $83 million. Gross margin in the second quarter of 2022 included the impact of a $2 million unrealized net mark-to-market gain on natural gas derivatives.

Second Quarter of 2023 Compared to Second Quarter of 2022
In September 2022, as a result of extremely high and volatile natural gas prices and the lack of a corresponding increase in global nitrogen product market prices, we idled ammonia production at our Billingham complex. Since that time, we have imported ammonia for upgrade into AN and other nitrogen products at that location.
Net Sales.    Net sales in our AN segment decreased $149 million, or 59%, to $104 million in the second quarter of 2023 from $253 million in the second quarter of 2022 due to a 51% decrease in average selling prices and a 15% decrease in sales volume. Average selling prices decreased to $282 per ton in the second quarter of 2023 compared to $580 per ton in the second quarter of 2022 due primarily to an increase in global supply availability as lower global energy costs drove higher global operating rates. Sales volume declined due primarily to weak domestic demand in the United Kingdom.
Cost of Sales.    Cost of sales in our AN segment averaged $220 per ton in the second quarter of 2023, a 36% decrease from $346 per ton in the second quarter of 2022. The decrease was due primarily to lower production costs for our Billingham complex in the second quarter of 2023 as purchased ammonia was used for upgrading into AN as compared to the higher-cost natural gas used to produce ammonia to upgrade into AN in the second quarter of 2022. In addition, the decrease in cost of sales

a decrease in average selling prices of 51%, which decreased gross margin by $84 million;
a decrease in sales volume of 15%, which decreased gross margin by $27 million;
a decrease in realized natural gas costs, which increased gross margin by $51 million, due primarily to the idling of our Billingham ammonia plant;
a net increase of $8 million in manufacturing, maintenance and other costs, driven by the cost for purchased ammonia for upgrade at our Billingham complex, partially offset by lower production costs; and
the impact of an $11 million unrealized net mark-to-market gain on natural gas derivatives in the second quarter of 2022.

Second Quarter of 2023 Compared to Second Quarter of 2022
In June 2022, we approved and announced our proposed plan to restructure our U.K. operations, including the planned permanent closure of our Ince facility. In August 2022, the final restructuring plan was approved, and decommissioning activities were initiated. We produced compound fertilizer products (NPKs), which are solid granular fertilizer products for which the nutrient content is a combination of nitrogen, phosphorus and potassium, only at our Ince facility, and closure of this facility resulted in our discontinuation of the NPK product line.
In September 2022, as a result of extremely high and volatile natural gas prices and the lack of a corresponding increase in global nitrogen product market prices, we idled ammonia production at our Billingham complex. Since that time, we have imported ammonia for upgrade into AN and other nitrogen products at that location.
Net Sales.    Net sales in our Other segment decreased by $74 million, or 35%, to $138 million in the second quarter of 2023 from $212 million in the second quarter of 2022 due to a 35% decrease in average selling prices, partially offset by a 1% increase in sales volume. The decrease in average selling prices was due primarily to an increase in global supply availability as lower global energy costs drove higher global operating rates.
Cost of Sales.    Cost of sales in our Other segment averaged $135 per ton in the second quarter of 2023, a 27% decrease from $184 per ton in the second quarter of 2022, due primarily to lower production costs for our Billingham complex in the second quarter of 2023 as purchased ammonia was used for upgrading into other nitrogen products as compared to the higher-cost natural gas used to produce ammonia to upgrade into other nitrogen products in the second quarter of 2022. In addition, the decrease in cost of sales per ton reflects lower realized natural gas costs in North America in the second quarter of 2023 compared to the second quarter of 2022.

Gross Margin.    Gross margin in our Other segment decreased by $48 million to $62 million in the second quarter of 2023 from $110 million in the second quarter of 2022, and our gross margin percentage was 44.9% in the second quarter of 2023 compared to 51.9% in the second quarter of 2022. The decrease in gross margin reflects the following:
a decrease in average selling prices of 35%, which decreased gross margin by $76 million;
a decrease in realized natural gas costs, which increased gross margin by $33 million, due primarily to the idling of our Billingham ammonia plant;
a net increase of $6 million in manufacturing, maintenance and other costs, driven by the cost for purchased ammonia for upgrade at our Billingham complex, partially offset by lower production costs;
an increase in sales volume of 1%, which increased gross margin by $4 million; and
the impact of a $3 million unrealized net mark-to-market gain on natural gas derivatives in the second quarter of 2022.
Six Months Ended June 30, 2023 Compared to Six Months Ended June 30, 2022
Net Sales.    Net sales in our Other segment decreased by $148 million, or 34%, to $289 million in the six months ended June 30, 2023 from $437 million in the six months ended June 30, 2022 due to a 33% decrease in average selling prices and a 2% decrease in sales volume. The decrease in average selling prices was due primarily to an increase in global supply availability as lower global energy costs drove higher global operating rates. The decrease in sales volume was due primarily to lower nitric acid, NPK and urea liquor sales volumes in the six months ended June 30, 2023, partially offset by higher DEF sales volumes.
Cost of Sales.    Cost of sales in our Other segment averaged $155 per ton in the six months ended June 30, 2023, a 17% decrease from $187 per ton in the six months ended June 30, 2022, due primarily to lower production costs for our Billingham complex in the first half of 2023 as purchased ammonia was used for upgrading into other nitrogen products as compared to the higher-cost natural gas used to produce ammonia to upgrade into other nitrogen products in the first half of 2022.
Gross Margin.    Gross margin in our Other segment decreased by $110 million to $121 million in the six months ended June 30, 2023 from $231 million in the six months ended June 30, 2022, and our gross margin percentage was 41.9% in the six months ended June 30, 2023 compared to 52.9% in the six months ended June 30, 2022. The decrease in gross margin reflects the following:
a decrease in average selling prices of 33%, which decreased gross margin by $138 million;
a decrease in realized natural gas costs, which increased gross margin by $45 million, due primarily to the idling of our Billingham ammonia plant;
a net increase of $19 million in manufacturing, maintenance and other costs, driven by the cost for purchased ammonia for upgrade at our Billingham complex, partially offset by lower production costs; and
a decrease in sales volume of 2%, which increased gross margin by $2 million due to favorable product mix.

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. We may also utilize our cash to fund acquisitions. In addition, we may from time to time seek to retire or purchase our outstanding debt through cash purchases, in open market or privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
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 revolving credit agreement.
As of June 30, 2023, our cash and cash equivalents balance was $3.22 billion, an increase of $896 million from $2.32 billion at December 31, 2022. At June 30, 2023, we were in compliance with all applicable covenant requirements under our revolving credit agreement and senior notes, and unused borrowing capacity under our revolving credit agreement was $750 million.
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.
Share Repurchase Programs
On November 3, 2021, our Board of Directors (the Board) authorized the repurchase of up to $1.5 billion of CF Holdings common stock through December 31, 2024 (the 2021 Share Repurchase Program). On November 2, 2022, the Board authorized the repurchase of up to $3 billion of CF Holdings common stock commencing upon completion of the 2021 Share Repurchase Program and effective through December 31, 2025 (the 2022 Share Repurchase Program). Repurchases under our share repurchase programs may be made from time to time in the open market, through privately negotiated transactions, through block transactions or otherwise. The manner, timing and amount of repurchases will be determined by our management based on the evaluation of market conditions, stock price, and other factors. Shares repurchased, including those repurchased under share repurchase programs, are retired as approved by the Board. The 2021 Share Repurchase Program was completed in the second quarter of 2023. The following table summarizes the share repurchases under the 2022 Share Repurchase Program and 2021 Share Repurchase Program.

CF INDUSTRIES HOLDINGS, INC.
In the six months ended June 30, 2023, we completed the 2021 Share Repurchase Program with the repurchase of approximately 2.3 million shares for $155 million. In the six months ended June 30, 2023, we repurchased approximately 0.8 million shares under the 2022 Share Repurchase Program for $50 million.
Capital Spending
We make capital expenditures to sustain our asset base, increase our capacity or capabilities, improve plant efficiency, comply with various environmental, health and safety requirements, and invest in our clean energy strategy. Capital expenditures totaled $164 million in the first six months of 2023 compared to $129 million in the first six months of 2022.
We currently anticipate that capital expenditures for the full year 2023 will be in the range of $500 to $550 million, which includes capital expenditures related to green and blue ammonia projects. Planned capital expenditures are generally 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, delays 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.
Agreement to Purchase Ammonia Production Facility
On March 20, 2023, we entered into an asset purchase agreement with DNLA and IPL. Under the terms of the agreement, we will purchase DNLA’s ammonia production complex located in Waggaman, Louisiana for a purchase price of $1.675 billion, subject to adjustment. The facility has a nameplate capacity of 880,000 tons of ammonia annually. The parties will allocate $425 million of the purchase price to a long-term ammonia offtake agreement providing for us to supply up to 200,000 tons of ammonia per year to IPL’s Dyno Nobel, Inc. subsidiary. We expect to fund the balance of the purchase price, representing the $1.675 billion purchase price, as adjusted, less $425 million, with cash on hand.
The consummation of the transaction is subject to the satisfaction or waiver of customary conditions, including, among others, the expiration or early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The agreement includes certain customary termination rights, including the right of either party to terminate the agreement if the closing has not occurred by March 20, 2025. We have agreed to pay a termination fee of $75 million if the agreement is terminated in certain circumstances and certain regulatory approvals are not obtained.
United Kingdom Operations
During the third quarter of 2021, the United Kingdom began experiencing an energy crisis that included a substantial increase in the price of natural gas, which impacted our U.K. operations. On September 15, 2021, we announced the halt of operations at both our Ince and Billingham manufacturing facilities in the United Kingdom due to negative profitability driven by the high cost of natural gas. Shortly thereafter, our Billingham facility resumed operations.
In June 2022, we approved and announced our proposed plan to restructure our U.K. operations, including the permanent closure of our Ince facility and optimization of the remaining manufacturing operations at the Billingham facility. In August 2022, the final restructuring plan was approved, and decommissioning activities at our Ince facility were initiated. As of June 30, 2023, the decommissioning of our Ince facility and other approved restructuring actions have been completed.
In September 2022, as a result of extremely high and volatile natural gas prices and the lack of a corresponding increase in global nitrogen product market prices, we idled ammonia production at our Billingham complex. With the ammonia plant idled since September 2022, production of AN and other nitrogen products has continued at our Billingham facility using imported ammonia, a portion of which is imported from our other ammonia production sites. In July 2023, we approved and announced our proposed plan to permanently close the Billingham ammonia plant. There remains uncertainty regarding the future cost of ammonia used for upgrading, natural gas and electricity, and selling prices for the products we produce in the United Kingdom. These factors, in addition to any remaining disposition activities at our Ince facility, could necessitate, among other things, additional funding to support the cash needs of our U.K. operations and recognition of further losses and could have an adverse impact on our results of operations and cash flows.

Debt
Revolving Credit Agreement
We have a senior unsecured revolving credit agreement (the Revolving Credit Agreement), which provides for a revolving credit facility of up to $750 million with a maturity of December 5, 2024. 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, capital expenditures, acquisitions, share repurchases and other general corporate purposes. CF Industries is the lead borrower, and CF Holdings is the sole guarantor, under the Revolving Credit Agreement.
Borrowings under the Revolving Credit Agreement may be denominated in U.S. dollars, Canadian dollars, euros and British pounds, and bear interest at a per annum rate equal to, at our option, an applicable adjusted term Secured Overnight Financing Rate or base rate plus, in either case, a specified margin. We 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.
As of June 30, 2023, we had unused borrowing capacity under the Revolving Credit Agreement of $750 million and no outstanding letters of credit under the Revolving Credit Agreement. There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2023 or December 31, 2022, or during the six months ended June 30, 2023.
The Revolving Credit Agreement contains representations and warranties and affirmative and negative covenants, including financial covenants. As of June 30, 2023, we were in compliance with all covenants under the Revolving Credit Agreement.
Letters of Credit
In addition to the letters of credit that may be issued under the Revolving Credit Agreement, as described above, we have also entered into a bilateral agreement with capacity to issue up to $350 million of letters of credit. As of June 30, 2023, approximately $205 million of letters of credit were outstanding under this agreement.

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 value, are received shortly after the contract is executed, with any remaining unpaid amount generally being collected by the time control transfers to the customer, 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 control transfers and revenue is recognized. As of June 30, 2023 and December 31, 2022, we had $9 million and $229 million, respectively, in customer advances on our consolidated balance sheets.
While customer advances are generally a significant source of liquidity, the level of forward sales contracts is affected by many factors, including current market conditions, our customers’ outlook of future market fundamentals and seasonality. 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 products. From time to time, we may 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. As of June 30, 2023, our open natural gas derivative contracts consisted of natural gas fixed price swaps, basis swaps and options for 43.8 million MMBtus of natural gas. As of December 31, 2022, our open natural gas derivative contracts consisted of natural gas fixed price swaps, basis swaps and options for 66.3 million MMBtus of natural gas.
Defined Benefit Pension Plans
We contributed $13 million to our pension plans in the six months ended June 30, 2023. Over the remainder of 2023, we expect to contribute approximately $34 million to our pension plans, which would result in our making total contributions of approximately $47 million to our pension plans for the full year 2023. In addition, in the two-year period from 2024 to 2025, we expect to contribute a total of approximately £30 million (or $38 million) to our U.K. plans, as agreed with the plans’ trustees.
Distribution to Noncontrolling Interest in CFN
On January 31, 2023, CFN distributed $255 million to CHS for the distribution period ended December 31, 2022. On July 31, 2023, the CFN Board of Managers approved semi-annual distribution payments for the distribution period ended June 30, 2023 in accordance with CFN’s limited liability company agreement. On July 31, 2023, CFN distributed $204 million to CHS for the distribution period ended June 30, 2023.
Cash Flows
Net cash provided by operating activities during the first six months of 2023 was $1.66 billion, a decrease of $621 million compared to $2.28 billion in the first six months of 2022. The decrease in cash flow from operations was due primarily to lower net earnings, partially offset by changes in net working capital. Net earnings for the first six months of 2023 was $1.26 billion compared to $2.39 billion for the first six months of 2022, a decrease of $1.13 billion. The decrease in net earnings was due primarily to a decrease in gross margin, driven by lower average selling prices. During the first six months of 2023, net changes in working capital increased cash flow from operations by $146 million, while in the first six months of 2022, net changes in working capital reduced cash flow from operations by $731 million. The increase in cash flow from working capital changes was attributable primarily to favorable movements in accounts receivable, inventory and customer advances in the first six

months of 2023 as compared to the first six months of 2022.
Net cash used in investing activities was $127 million in the first six months of 2023 as compared to $121 million in the first six months of 2022. Capital expenditures totaled $164 million during the first six months of 2023 compared to $129 million in the first six months of 2022. Proceeds from the sale of emission credits was $36 million in the first six months of 2023 compared to $12 million in the first six months of 2022.
Net cash used in financing activities was $639 million in the first six months of 2023 compared to $1.40 billion in the first six months of 2022. The decrease was due primarily to a decrease in share repurchases. In the first six months of 2023, we paid $205 million for share repurchases compared to $577 million paid for share repurchases in the first six months of 2022. In addition, we paid $507 million in connection with the redemption of the 2023 Notes in the first six months of 2022.

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 gross margin, cash flows and estimates of future cash flows related to nitrogen-based products are sensitive not only to selling prices of our products, but also to changes in market prices of natural gas and other raw materials except to the extent the prices we pay for those inputs 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 products. At certain times, we have managed the risk of changes in natural gas prices through the use of derivative financial instruments. The derivative instruments that we may use for this purpose are primarily natural gas fixed price swaps, basis swaps and options. These derivatives settle using primarily a NYMEX futures price index, which represents 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, 2023, we had natural gas derivative contracts covering certain periods through March 2024.
As of June 30, 2023 and December 31, 2022, we had open derivative contracts for 43.8 million MMBtus and 66.3 million MMBtus, respectively. A $1.00 per MMBtu increase in the forward curve prices of natural gas at June 30, 2023 would result in a favorable change in the fair value of these derivative positions of approximately $41 million, and a $1.00 per MMBtu decrease in the forward curve prices of natural gas would change their fair value unfavorably by approximately $41 million.
From time to time, we may purchase nitrogen products on the open market to augment or replace production at our facilities.
Interest Rates
As of June 30, 2023, we had four series of senior notes totaling $3.00 billion of principal outstanding with maturity dates of December 1, 2026, March 15, 2034, June 1, 2043, and March 15, 2044. The senior notes have fixed interest rates. As of June 30, 2023, the carrying value and fair value of our senior notes was approximately $2.97 billion and $2.77 billion, respectively.
Borrowings under the Revolving Credit Agreement bear current market rates of interest, and we are subject to interest rate risk on such borrowings. There were no borrowings outstanding under the Revolving Credit Agreement as of June 30, 2023, as of December 31, 2022, or during the six months ended June 30, 2023.
Foreign Currency Exchange Rates
We are directly exposed to changes in the value of the Canadian dollar, the British pound and the euro. We generally do not maintain any exchange rate derivatives or hedges related to these currencies.
