Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	Background and Basis of Presentation We are a leading global fertilizer and chemical company with outstanding operational capabilities and a highly cost advantaged production and distribution platform. Our 3,000 employees operate world-class manufacturing complexes in Canada, the United Kingdom and the United States. Our principal customers are cooperatives, independent fertilizer distributors, farmers and industrial users. Our principal nitrogen fertilizer products are ammonia, granular urea, urea ammonium nitrate solution (UAN) and ammonium nitrate (AN). Our other nitrogen products include diesel exhaust fluid (DEF), urea liquor, nitric acid and aqua ammonia, which are sold primarily to our industrial customers, and compound fertilizer products (NPKs), which are solid granular fertilizer products for which the nutrient content is a combination of nitrogen, phosphorus, and potassium. We serve our customers in North America through an unparalleled production, storage, transportation and distribution network. We also reach a global customer base with exports from our Donaldsonville, Louisiana, plant, the world’s largest and most flexible nitrogen complex. Additionally, we move product to international destinations from our Yazoo City, Mississippi, facility, and our Billingham and Ince facilities in the United Kingdom, and from a joint venture ammonia facility in the Republic of Trinidad and Tobago in which we own a 50 percent interest. All references to “CF Holdings,” “the Company,” “we,” “us” and “our” refer to CF Industries Holdings, Inc. and its subsidiaries, except where the context makes clear that the reference is only to CF Industries Holdings, Inc. itself and not its subsidiaries. All references to “CF Industries” refer to CF Industries, Inc., a 100% owned subsidiary of CF Industries Holdings, Inc. The accompanying unaudited interim consolidated financial statements have been prepared on the same basis as our audited consolidated financial statements for the year ended December 31, 2017 , in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial reporting. In the opinion of management, these statements reflect all adjustments, consisting only of normal and recurring adjustments, that are necessary for the fair representation of the information for the periods presented. The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Operating results for any period presented apply to that period only and are not necessarily indicative of results for any future period. The accompanying unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and related disclosures included in our 2017 Annual Report on Form 10-K filed with the SEC on February 22, 2018. The preparation of the unaudited interim consolidated financial statements requires us to make use of estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the unaudited consolidated financial statements and the reported revenues and expenses for the periods presented. Significant estimates and assumptions are used for, but are not limited to, net realizable value of inventories, environmental remediation liabilities, environmental and litigation contingencies, the cost of customer incentives, useful lives of property and identifiable intangible assets, the assumptions used in the evaluation of potential impairments of property, investments, identifiable intangible assets and goodwill, income tax and valuation reserves, allowances for doubtful accounts receivable, the measurement of the fair values of investments for which markets are not active, assumptions used in the determination of the funded status and annual expense of defined benefit pension and other postretirement benefit plans and the assumptions used in the valuation of stock-based compensation awards granted to employees. During the first quarter of 2018, we adopted Accounting Standards Update (ASU) No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. As a result, we reclassified certain amounts in our consolidated statements of operations for the three months ended March 31, 2017 . See Note 2—New Accounting Standards for additional information. During the first quarter of 2018, we adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. As a result, in our consolidated statements of cash flows for the three months ended March 31, 2017 , we have reclassified $1 million of withdrawals from restricted cash funds, previously classified as cash flows provided by investing activities, to be included in the reconciliation of the beginning and ending balances of cash, cash equivalents and restricted cash. See Note 2—New Accounting Standards for additional information.

New Accounting Standards

New Accounting Standards	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
New Accounting Standards	New Accounting Standards Recently Adopted Pronouncements On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments. Additionally, the costs to obtain and fulfill a contract, including assets to be recognized, are to be capitalized and such capitalized costs should be disclosed. In 2016, the Financial Accounting Standards Board (FASB) issued additional ASUs that enhanced the operability of the principal versus agent guidance in ASU No. 2014-09 by clarifying that an entity should consider the nature of each good or service promised to a customer at the individual good or service level, clarified that ASU No. 2014-09 should not be applied to immaterial performance obligations, and enhanced the guidance around the treatment of shipping costs incurred to fulfill performance obligations. Our adoption of this ASU, utilizing the modified retrospective approach on contracts that were not completed as of January 1, 2018, resulted in a reduction to opening retained earnings of $1 million related to the cumulative difference between ASC 605 and ASC 606. See Note 3—Revenue Recognition for additional information. On January 1, 2018, we adopted ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities, which changes the income statement impact of equity investments held by an entity. The amendments require the unrealized gains or unrealized losses of equity instruments measured at fair value to be recognized in net income. Our adoption of this ASU resulted in an increase to opening retained earnings of $1 million representing the cumulative effect of unrealized gains from equity securities from accumulated other comprehensive income (loss). On January 1, 2018, we adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash - a consensus of the FASB Emerging Issues Task Force, which requires that the statement of cash flows include amounts described as restricted cash and restricted cash equivalents as part of cash and cash equivalents when reconciling the beginning and ending period total amounts. Upon adoption of this ASU, $1 million of withdrawals from restricted cash funds previously reflected as cash provided by investing activities for the three months ended March 31, 2017, and our restricted cash of $5 million and $4 million as of December 31, 2016 and March 31, 2017, respectively, were reclassified to be included within the reconciliation of beginning and ending cash, cash equivalents and restricted cash balances on our consolidated statement of cash flows. On January 1, 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changed the presentation of net benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Only service cost can be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net benefit cost must be presented separately outside of operating income. Additionally, only service costs may be capitalized on the balance sheet. Our adoption of this ASU was applied retrospectively for the income statement classification requirements and prospectively for the capitalization guidance, which resulted in $1 million of net benefit cost previously recognized in cost of sales to be reclassifed to other non-operating on our consolidated statement of operations for the three months ended March 31, 2017. On January 1, 2018, we adopted ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Our adoption of this ASU had no impact on our consolidated financial statements. Recently Issued Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in ASC Topic 840, Leases. This ASU will require lessees to recognize the rights and obligations resulting from virtually all leases (other than leases that meet the definition of a short-term lease) on their balance sheets as right-of-use assets with corresponding lease liabilities. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of income and expense recognized and expected to be recognized from existing contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and requires the modified retrospective method of adoption. While we are continuing to evaluate the impact of the adoption of this ASU on our consolidated financial statements, we currently believe the most significant change relates to the recognition of the right-of-use assets and lease liabilities on our balance sheet for operating leases for certain property and equipment, including transportation equipment utilized for the distribution of our products. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships in order to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and should be applied to existing hedging relationships as of the date of adoption. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and for interim periods therein. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.

Revenue Recognition

Revenue Recognition	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The revenue that we recognize arises from contracts we have with our customers. Our performance obligations under a contract correspond to each shipment of product that we make to our customer under the contract; as a result each contract may have more than one performance obligation based on the number of products ordered, the quantity of product to be shipped and the mode of shipment requested by the customer. Control of our products transfers to our customers when the customer is able to direct the use of, and obtain substantially all of the benefits from, our products, which generally occurs at the later of when the customer obtains title to our product or when the customer assumes risk of loss of our product. The transfer of control generally occurs at a point in time upon loading of our product onto transportation equipment or upon delivery to the customer’s intended destination. Once this occurs, we have satisfied our performance obligation and we recognize revenue. When we enter into a contract with a customer, we are obligated to provide the product during a mutually agreed upon time period. Depending on the terms of the contract, either we or the customer arranges delivery of the product to the customer’s intended destination. In situations where we have agreed to arrange delivery of the product to the customer’s intended destination and control of the product transfers upon loading of our product onto transportation equipment, we have elected to account for any freight income associated with the delivery of these products as freight revenue, since this activity fulfills our obligation to transfer the product to the customer. For the three months ended March 31, 2018 , the total amount of freight recognized as revenue was not material. Certain of our contracts require us to supply products on a continuous basis to the customer. We recognize revenue on these contracts based on the quantity of products transferred to the customer during the period. For the three months ended March 31, 2018 , the amount of revenue for these types of transactions was $25 million . From time to time, we will enter into the marketplace to purchase the needed product in order to meet our customer contracts. When we purchase product to meet customer contracts, we are the principal in the transaction and recognize revenue on a gross basis. As discussed in Note 8—Equity Method Investments , we have transactions in the normal course of business with Point Lisas Nitrogen Limited (PLNL), reflecting our obligation to purchase 50% of the ammonia produced by PLNL at current market prices. For the three months ended March 31, 2018 , other than products purchased from PLNL, we did not purchase any products in the marketplace in order to meet our customer contracts. Transaction Price We agree with our customers on the selling price of each transaction. This transaction price is generally based on the product, market conditions, including supply and demand balances, freight arrangements including where control transfers, and customer incentives. In our contracts with customers, we allocate the entire transaction price to the sale of product to the customer, which is the basis for the determination of the relative standalone selling price allocated to each performance obligation. Returns of our product by our customers are permitted only when the product is not to specification, and were not material for the three months ended March 31, 2018. Any sales tax, value added tax, and other tax we collect concurrently with our revenue-producing activities are excluded from revenue. We offer cash incentives to certain customers based on the volume of their purchases over a certain period. These incentives do not provide an option to the customer for additional product. Customer incentives are reported as a reduction in net sales. Accrual of these incentives involves the use of estimates, including how much product the customer will purchase and whether the customer will achieve a certain level of purchases within the incentive period. The balances of customer incentives accrued at March 31, 2018, and December 31, 2017 were not material. If we continued to apply legacy revenue recognition guidance for the first three months of 2018, our revenues, gross margin, and net income attributable to common shareholders would not have been materially different. See Note 2—New Accounting Standards for the impact of our adoption of ASU No. 2014-09. Revenue Disaggregation We track our revenue by product and by geography. See Note 17—Segment Disclosures for our revenue by reportable segment, which are ammonia, granular urea, UAN, AN, and Other. The following table summarizes our revenue by product and by geography (based on destination of our shipment) for the three months ended March 31, 2018 : Ammonia Granular UAN AN Other Total (in millions) Three months ended March 31, 2018 North America $ 168 $ 264 $ 246 $ 45 $ 59 $ 782 Europe and other 44 — 37 55 39 175 Total revenue $ 212 $ 264 $ 283 $ 100 $ 98 $ 957 Accounts Receivable and Customer Advances Our customers purchase our products through sales on credit or forward sales. Products sold to our customers on credit are recorded as accounts receivable when the customer obtains control of the product. Customers that purchase our products on credit are required to pay in accordance with our customary payment terms, which are generally less than 30 days. For the three months ended March 31, 2018 , the amount of customer bad debt expense recognized was immaterial. For forward sales, the customer prepays a portion of the value of the sales contract prior to obtaining control of the product. These prepayments, when received, are recorded as customer advances and are recognized as revenue when the customer obtains control of the product. Forward sales are customarily offered for periods of less than one year in advance of when the customer obtains control of the product. As of March 31, 2018 and December 31, 2017 , we had $154 million and $89 million , respectively, in customer advances on our consolidated balance sheets. The increase in the balance of customer advances was primarily caused by customers purchasing fertilizer for future delivery in anticipation of the spring application season and improvement in the current conditions of the fertilizer market. During the three months ended March 31, 2018, we recognized approximately $65 million of revenue related to customer advances that were on our consolidated balance sheet as of December 31, 2017. We expect that all of our customer advances that were recorded as of December 31, 2017, will be recognized as revenue during 2018. We have certain customer contracts with performance obligations that extend beyond one year and if the customer does not take the required amount of product specified in the contract, then the customer is required to make a payment to us, which may vary based upon the terms and conditions of the applicable contract. As of March 31, 2018, the minimum product tonnage to be sold under such contracts with original contract durations of more than one year are as follows: Ammonia Granular UAN AN (1) Other Total (tons in thousands) (2) Remainder of 2018 443 26 — 398 52 919 2019 594 29 — — 70 693 2020 577 — — — 70 647 2021 577 — — — 70 647 2022 577 — — — 70 647 2019 - 2021 (1) — — — 1,122 — 1,122 Total 2,768 55 — 1,520 332 4,675 _____________________________________________________________________________ (1) The AN contracts in the table above have minimum purchase requirements for the current year and over a contractually specified period. As of March 31, 2018, since the annual minimum purchase requirements have not been set past the current year, the table indicates the remaining amount for the current year and a total remaining amount for the contractually specified 2019 - 2021 period. (2) CF has contracts with customers that contain minimum purchase requirements that have original contract durations of one year or less in length that are not included in the above table. The amount of revenue recognized on these obligations at the time control transfers to our customer will be based on the agreed upon price with our customer that is specified in the customer contract. Other than in the table above, any performance obligations with our customers that were unfulfilled or partially filled at December 31, 2017 will be satisfied in 2018. All of our contracts require that the period between the payment for goods and the transfer of those goods to the customer occur within normal contractual terms that do not exceed one year; therefore, we have not adjusted the transaction price of any of our contracts to recognize a significant financing component. We have also expensed any incremental costs associated with obtaining a contract that has a duration of less than one year, and there were no costs capitalized during the three months ending March 31, 2018 .

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Equity Method Investments We have a 50% ownership interest in PLNL, which operates an ammonia production facility in the Republic of Trinidad and Tobago. We include our share of the net earnings from this equity method investment as an element of earnings from operations because PLNL provides additional production to our operations and is integrated with our other supply chain and sales activities in the ammonia segment. As of March 31, 2018 , the total carrying value of our equity method investment in PLNL of $100 million was $51 million more than our share of PLNL’s book value. The excess is attributable to the purchase accounting impact of our acquisition of the investment in PLNL and reflects the revaluation of property, plant and equipment. The increased basis for property, plant and equipment is being amortized over a remaining period of approximately 15 years . Our equity in earnings of PLNL is different from our ownership interest in income reported by PLNL due to amortization of this basis difference. We have transactions in the normal course of business with PLNL reflecting our obligation to purchase 50% of the ammonia produced by PLNL at current market prices. Our ammonia purchases from PLNL totaled $29 million and $20 million for the three months ended March 31, 2018 and 2017 , respectively.

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. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present assets and liabilities included in our consolidated balance sheets as of March 31, 2018 and December 31, 2017 that are recognized at fair value on a recurring basis, and indicate the fair value hierarchy utilized to determine such fair value: March 31, 2018 Total Fair Value Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Cash equivalents $ 464 $ 464 $ — $ — Nonqualified employee benefit trusts 19 19 — — Derivative liabilities (9 ) — (9 ) — Embedded derivative liability (25 ) — (25 ) — December 31, 2017 Total Fair Value Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Cash equivalents $ 715 $ 715 $ — $ — Nonqualified employee benefit trusts 19 19 — — Derivative assets 1 — 1 — Derivative liabilities (12 ) — (12 ) — Embedded derivative liability (25 ) — (25 ) — Cash Equivalents As of March 31, 2018 and December 31, 2017 , our cash equivalents consisted primarily of U.S. and Canadian government obligations and money market mutual funds that invest in U.S. government obligations and other investment-grade securities. Nonqualified Employee Benefit Trusts We maintain trusts associated with certain nonqualified supplemental pension plans. The fair values of the trust assets are based on daily quoted prices in an active market, which represent the net asset values of the shares held in the trusts, and are included on our consolidated balance sheets in other assets. Debt securities are accounted for as available-for sale securities. In the first quarter of 2018, as a result of our adoption of ASU 2016-01, changes in the fair value of equity securities in the trust assets are recognized through earnings. See Note 2—New Accounting Standards for additional information. Derivative Instruments The derivative instruments that we use are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options traded in the over-the-counter (OTC) markets with multinational commercial banks, other major financial institutions or large energy companies. The natural gas derivative contracts represent anticipated natural gas needs for future periods and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods. The natural gas derivative contracts settle using primarily NYMEX futures prices. To determine the fair value of these instruments, we use quoted market prices from NYMEX and standard pricing models with inputs derived from or corroborated by observable market data such as forward curves supplied by an industry-recognized independent third party. See Note 13—Derivative Financial Instruments for additional information. Embedded Derivative Liability Under the terms of our strategic venture with CHS Inc. (CHS), if our credit rating as determined by two of three specified credit rating agencies is below certain levels, we are required to make a non-refundable yearly payment of $5 million to CHS. Since our credit ratings were below certain levels in 2016 and 2017, we made a payment of $5 million to CHS in each year. These payments will continue on a yearly basis until the earlier of the date that our credit rating is upgraded to or above certain levels by two of the three specified credit rating agencies or February 1, 2026. This obligation is recognized on our consolidated balance sheets as an embedded derivative. As of March 31, 2018 and December 31, 2017, the embedded derivative liability of $25 million is included in other current liabilities and other liabilities on our consolidated balance sheets. The inputs into the fair value measurement include the probability of future upgrades and downgrades of our credit rating based on historical credit rating movements of other public companies and the discount rates to be applied to potential annual payments based on applicable credit spreads of other public companies at different credit rating levels. Based on these inputs, our fair value measurement is classified as Level 2. For the three months ended March 31, 2017 , we recognized a charge of $1 million related to the embedded derivative, which is included in other operating—net in our consolidated statement of operations. See Note 14—Noncontrolling Interests for additional information regarding our strategic venture with CHS. Financial Instruments The carrying amount and estimated fair value of our financial instruments are as follows: March 31, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value (in millions) Long-term debt $ 4,693 $ 4,579 $ 4,692 $ 4,800 The fair value of our long-term debt was based on quoted prices for identical or similar liabilities in markets that are not active or valuation models in which all significant inputs and value drivers are observable and, as a result, they are classified as Level 2 inputs. The carrying amounts of cash and cash equivalents, as well as instruments included in other current assets and other current liabilities that meet the definition of financial instruments, approximate fair values because of their short-term maturities. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis We also have assets and liabilities that may be measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment, allocation of purchase price in an acquisition or when a new liability is being established that requires fair value measurement. These include long-lived assets, goodwill and other intangible assets and investments in unconsolidated subsidiaries, such as equity method investments, which may be written down to fair value as a result of impairment. The fair value measurements related to each of these rely primarily on Company-specific inputs and the Company’s assumptions about the use of the assets. Since certain of the Company’s assumptions would involve inputs that are not observable, these fair values would reside within Level 3 of the fair value hierarchy.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2018 , we recorded an income tax provision of $17 million on pre-tax income of $105 million , or an effective tax rate of 15.8% , compared to an income tax benefit of $13 million on a pre-tax loss of $22 million , or an effective tax rate of 59.2% , for the three months ended March 31, 2017 . Our effective tax rate in the first quarter of 2018 is based on the U.S. federal tax rate of 21% as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, as compared to the U.S. federal tax rate of 35% that was applicable in the first quarter of 2017. Our effective tax rate in both periods is impacted by earnings attributable to noncontrolling interests in CF Industries Nitrogen, LLC (CFN) and Terra Nitrogen Company, L.P. (TNCLP), as our consolidated income tax provision (benefit) does not include a tax provision on the earnings attributable to the noncontrolling interests. Our effective tax rate for the three months ended March 31, 2018 and 2017 , exclusive of the earnings attributable to the noncontrolling interests of $25 million and $14 million , respectively, would be 20.8% and 35.9% , respectively. See Note 14—Noncontrolling Interests for additional information. During the fourth quarter of 2017, we recorded the impact of the Tax Cuts and Jobs Act that was enacted on December 22, 2017, including a provisional amount for the impact of the transition tax liability based on amounts reasonably estimable. We have not recorded measurement period adjustments to this provisional amount in the three months ended March 31, 2018 . During the third quarter of 2016, one of our Canadian subsidiaries received a Notice of Reassessment from the Canada Revenue Agency (CRA) for tax years 2006 through 2009 asserting a disallowance of certain patronage allocations. The tax assessment of CAD $174 million (or approximately $135 million ), including provincial taxes but excluding any interest or penalties, is the result of an audit that was initiated by the CRA in January 2010 and involves the sole issue of whether certain patronage allocations meet the requirements for deductibility under the Income Tax Act of Canada. The reassessment has been appealed and a letter of credit in the amount of CAD $87 million (or approximately $67 million ) has been posted. We believe that it is more likely than not that the patronage allocation deduction will ultimately be sustained. In the event that we do not prevail in the appeal, we should be entitled to a U.S. foreign tax credit against any incremental Canadian tax paid. This issue is currently under review by the competent authorities of Canada and the United States.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We use derivative financial instruments primarily to reduce our exposure to changes in commodity prices. Natural gas is the largest and most volatile component of the manufacturing cost for nitrogen-based products. We manage the risk of changes in natural gas prices primarily through the use of derivative financial instruments. The derivatives that we use for this purpose are primarily natural gas fixed price swaps, natural gas basis swaps and natural gas options traded in the OTC markets. These natural gas derivatives settle using primarily a NYMEX futures price index, which represents the basis for fair value at any given time. We enter into natural gas derivative contracts with respect to natural gas to be consumed by us in the future, and settlements of those derivative contracts are scheduled to coincide with our anticipated purchases of natural gas used to manufacture nitrogen products during those future periods. We use natural gas derivatives as an economic hedge of natural gas price risk, but without the application of hedge accounting. As a result, changes in fair value of these contracts are recognized in earnings. As of March 31, 2018 , we had natural gas NYMEX fixed price swaps covering periods through December 2018 and natural gas basis swaps covering certain periods through March 2019. As of March 31, 2018 and December 31, 2017 , we had open natural gas derivative contracts, including natural gas fixed price swaps and natural gas basis swaps, for 27.7 million MMBtus (millions of British thermal units) and 35.9 million MMBtus, respectively. For the three months ended March 31, 2018 , we used natural gas NYMEX fixed price swaps to cover approximately 9% of our natural gas consumption. The effect of derivatives in our consolidated statements of operations is shown in the table below.

As of March 31, 2018 and December 31, 2017 , none of our derivative instruments were designated as hedging instruments. See Note 9—Fair Value Measurements for additional information on derivative fair values.

In the event of certain defaults or a credit ratings downgrade, our counterparty may request early termination and net settlement of certain derivative trades or may require us to collateralize derivatives in a net liability position. The Revolving Credit Agreement, at any time when it is secured, provides a cross collateral feature for those of our derivatives that are with counterparties that are party to, or affiliates of parties to, the Revolving Credit Agreement so that no separate collateral would be required for those counterparties in connection with such derivatives. In the event the Revolving Credit Agreement becomes unsecured, separate collateral could be required in connection with such derivatives. As of March 31, 2018 and December 31, 2017 , the aggregate fair value of the derivative instruments with credit-risk-related contingent features in net liability positions was $9 million and $12 million , respectively, which also approximates the fair value of the maximum amount of additional collateral that would need to be posted or assets needed to settle the obligations if the credit-risk-related contingent features were triggered at the reporting dates. As of March 31, 2018 and December 31, 2017 , we had no cash collateral on deposit with counterparties for derivative contracts. The credit support documents executed in connection with certain of our ISDA agreements generally provide us and our counterparties the right to set off collateral against amounts owing under the ISDA agreements upon the occurrence of a default or a specified termination event. The following table presents amounts relevant to offsetting of our derivative assets and liabilities as of March 31, 2018 and December 31, 2017 : Amounts presented in consolidated balance sheets (1) Gross amounts not offset in consolidated balance sheets Financial instruments Cash collateral received (pledged) Net amount (in millions) March 31, 2018 Total derivative assets $ — $ — $ — $ — Total derivative liabilities (9 ) — — (9 ) Net derivative liabilities $ (9 ) $ — $ — $ (9 ) December 31, 2017 Total derivative assets $ 1 $ 1 $ — $ — Total derivative liabilities (12 ) (1 ) — (11 ) Net derivative liabilities $ (11 ) $ — $ — $ (11 ) _______________________________________________________________________________ (1) We report the fair values of our derivative assets and liabilities on a gross basis on our consolidated balance sheets. As a result, the gross amounts recognized and net amounts presented in the table above are the same. We do not believe the contractually allowed netting, close-out netting or setoff of amounts owed to, or due from, the counterparties to our ISDA agreements would have a material effect on our financial position.

We own the remaining membership interest. Under the terms of CFN’s limited liability company agreement, each member’s interest will reflect, over time, the impact of the profitability of CFN and any member contributions made to, and distributions received from, CFN. For financial reporting purposes, the assets, liabilities and earnings of the strategic venture are consolidated into our financial statements. CHS’ interest in the strategic venture is recorded in noncontrolling interests in our consolidated financial statements. On February 1, 2016, CHS also began receiving 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 minority equity interest in CFN, CHS is entitled to semi-annual cash distributions from CFN. We are also entitiled to semi-annual cash distributions from CFN. The amounts of distributions from CFN to us and CHS are based generally on the profitability of CFN and determined based on the volume of granular urea and UAN sold by CFN to us and CHS pursuant to supply agreements, less a formula driven amount based primarily on the cost of natural gas used to produce the granular urea and UAN, and adjusted for the allocation of items such as operational efficiencies and overhead amounts. Additionally, under the terms of the strategic venture, we recognized an embedded derivative related to our credit rating. See Note 9—Fair Value Measurements for additional information. Terra Nitrogen Company, L.P. (TNCLP) On February 7, 2018, we announced that, in accordance with the terms of TNCLP’s First Amended and Restated Agreement of Limited Partnership (as amended by Amendment No. 1 to the First Amended and Restated Agreement of Limited Partnership, the TNCLP Agreement of Limited Partnership), Terra Nitrogen GP Inc. (TNGP), the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP (the Public Units). TNGP completed its purchase of the Public Units on April 2, 2018 (the Purchase) for an aggregate cash purchase price of $388 million . Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP. See Note 19—Subsequent Event for additional information. As of March 31, 2018, TNCLP was a master limited partnership (MLP) that owned a nitrogen fertilizer manufacturing facility in Verdigris, Oklahoma. As of March 31, 2018, we owned approximately 75.3% of TNCLP through general and limited partnership interests and outside investors owned the remaining approximately 24.7% of the limited partnership. For financial reporting purposes, the assets, liabilities and earnings of the partnership have been consolidated into our financial statements. The outside investors’ limited partnership interests in the partnership have been recorded in noncontrolling interests in our consolidated financial statements. The noncontrolling interest represents the noncontrolling unitholders’ interest (prior to the Purchase) in the earnings and equity of TNCLP. Affiliates of CF Industries were required to purchase all of TNCLP’s fertilizer products at market prices as defined in the Amendment to the General and Administrative Services and Product Offtake Agreement, dated September 28, 2010. Prior to April 2, 2018, TNCLP made cash distributions to the general and limited partners based on formulas defined within the TNCLP Agreement of Limited Partnership. Cash available for distribution (Available Cash) was defined in the TNCLP Agreement of Limited Partnership generally as all cash receipts less all cash disbursements, less certain reserves (including reserves for future operating and capital needs) established as the general partner determined in its reasonable discretion to be necessary or appropriate. Changes in working capital affected Available Cash, as increases in the amount of cash invested in working capital items (such as increases in receivables or inventory and decreases in accounts payable) reduced Available Cash, while declines in the amount of cash invested in working capital items increased Available Cash. Cash distributions to the limited partners and general partner varied depending on the extent to which the cumulative distributions exceeded certain target threshold levels set forth in the TNCLP Agreement of Limited Partnership. In the first quarter of 2017 , the minimum quarterly distributions under the TNCLP Agreement of Limited Partnership were satisfied, which entitled TNGP to receive incentive distributions on its general partner interests (in addition to minimum quarterly distributions). TNGP assigned its right to receive such incentive distributions to an affiliate of TNGP that was also an indirect wholly owned subsidiary of CF Holdings. The earnings attributed to our general partner interest in excess of the threshold levels for the three months ended March 31, 2017 was $3 million .

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation West Fertilizer Co. On April 17, 2013, there was a fire and explosion at the West Fertilizer Co. fertilizer storage and distribution facility in West, Texas. According to published reports, 15 people were killed and approximately 200 people were injured in the incident, and the fire and explosion damaged or destroyed a number of homes and buildings around the facility. Various subsidiaries of CF Industries Holdings, Inc. (the CF Entities) have been named as defendants along with other companies in lawsuits filed in 2013, 2014 and 2015 in the District Court of McLennan County, Texas by the City of West, individual residents of the County and other parties seeking recovery for damages allegedly sustained as a result of the explosion. The cases have been consolidated for discovery and pretrial proceedings in the District Court of McLennan County under the caption “In re: West Explosion Cases.” The two-year statute of limitations expired on April 17, 2015. As of that date, over 400 plaintiffs had filed claims, including at least 9 entities, 325 individuals, and 80 insurance companies. Plaintiffs allege various theories of negligence, strict liability, and breach of warranty under Texas law. Although we do not own or operate the facility or directly sell our products to West Fertilizer Co., products that the CF Entities have manufactured and sold to others have been delivered to the facility and may have been stored at the West facility at the time of the incident. The Court granted in part and denied in part the CF Entities’ Motions for Summary Judgment in August 2015. Over one hundred sixty cases have been resolved pursuant to confidential settlements that have been or we expect will be fully funded by insurance. The remaining cases are in various stages of discovery and pre-trial proceedings. The next trial is scheduled for July 2018. We believe we have strong legal and factual defenses and intend to continue defending the CF Entities vigorously in the pending lawsuits. The Company cannot provide a range of reasonably possible loss due to the lack of damages discovery for many of the remaining claims and the uncertain nature of this litigation, including uncertainties around the potential allocation of responsibility by a jury to other defendants or responsible third parties. The recognition of a potential loss in the future in the West Fertilizer Co. litigation could negatively affect our results in the period of recognition. However, based upon currently available information, including available insurance coverage, we do not believe that this litigation will have a material adverse effect on our consolidated financial position, results of operations or cash flows. Other Litigation From time to time, we are subject to ordinary, routine legal proceedings related to the usual conduct of our business, including proceedings regarding public utility and transportation rates, environmental matters, taxes and permits relating to the operations of our various plants and facilities. Based on the information available as of the date of this filing, we believe that the ultimate outcome of these routine matters will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. Environmental Louisiana Environmental Matters Clean Air Act—Ozone Attainment Designation Our Donaldsonville nitrogen complex is located in a five-parish region near Baton Rouge, Louisiana. On December 15, 2016, the EPA redesignated the Baton Rouge Nonattainment Area as “attainment” with respect to the 2008 8-hour ozone national ambient air quality standard (NAAQS). However, based on 2013-2015 air quality monitoring data, the State of Louisiana recommended that the EPA designate the Baton Rouge area as “non-attainment” pursuant to the updated 2015 8-hour ozone standard. On December 20, 2017, the EPA notified the state of Louisiana that it intends to designate the Baton Rouge area as non-attainment for the 2015 ozone standard. On January 5, 2018, the EPA published notice of a public comment period with respect to the proposed attainment/non-attainment designations of certain air quality regions, including the Baton Rouge area. The EPA subsequently determined, based on certified air emissions data for calendar year 2017, that the air quality monitors for the Baton Rouge area are attaining the 2015 standard. As a result, on April 30, 2018, the EPA Administrator signed a notice designating the Baton Rouge area as “attainment/unclassifiable” with respect to the 2015 ozone standard. Designation of the Baton Rouge area as nonattainment with respect to the 2015 ozone standard could have resulted in more stringent air pollution emissions limits for our existing operation and would have subjected our facilities to more stringent requirements to obtain approvals for plant expansions, or made it more difficult to obtain such approvals. Other CERCLA/Remediation Matters From time to time, we receive notices from governmental agencies or third parties alleging that we are a potentially responsible party at certain cleanup sites under CERCLA or other environmental cleanup laws. In 2011, we received a notice from the Idaho Department of Environmental Quality (IDEQ) that alleged that we were a potentially responsible party for the cleanup of a former phosphate mine site we owned in the late 1950s and early 1960s located in Georgetown Canyon, Idaho. The current owner of the property and a former mining contractor received similar notices for the site. In 2014, we and the current property owner entered into a Consent Order with IDEQ and the U.S. Forest Service to conduct a remedial investigation and feasibility study of the site. In 2015, we and several other parties received a notice that the U.S. Department of the Interior and other trustees intend to undertake a natural resource damage assessment for 17 former phosphate mines in southeast Idaho, one of which is the former Georgetown Canyon mine. We are not able to estimate at this time our potential liability, if any, with respect to the cleanup of the site or a possible claim for natural resource damages. However, based on currently available information, we do not expect the remedial or financial obligations to which we may be subject involving this or other cleanup sites will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Segment Reporting [Abstract]
Segment Disclosures	Segment Disclosures Our reportable segments consist of ammonia, granular urea, UAN, AN and Other. These segments are differentiated by products. Our management uses gross margin to evaluate segment performance and allocate resources. Total other operating costs and expenses (consisting of selling, general and administrative expenses and other operating—net) and non-operating expenses (interest and income taxes) are centrally managed and are not included in the measurement of segment profitability reviewed by management. Our assets, with the exception of goodwill, are not monitored by or reported to our chief operating decision maker by segment; therefore, we do not present total assets by segment. Goodwill by segment is presented in Note 7—Goodwill and Other Intangible Assets . Segment data for sales, cost of sales and gross margin for the three months ended March 31, 2018 and 2017 are presented in the tables below.

Condensed Consolidating Financial Statements
Condensed Consolidating Financial Statements	Condensed Consolidating Financial Statements The following condensed consolidating financial information is presented in accordance with SEC Regulation S-X Rule 3-10, Financial statements of guarantors and issuers of guaranteed securities registered or being registered , and relates to (i) the senior notes due 2020, 2023, 2034, 2043 and 2044 (described in Note 12—Financing Agreements and referred to in this report as the Public Senior Notes) issued by CF Industries, Inc. (CF Industries), a 100% owned subsidiary of CF Industries Holdings, Inc. (Parent), and guarantees of the Public Senior Notes by Parent and by CFE, CFS and CF USA (the Subsidiary Guarantors), which are 100% owned subsidiaries of Parent, and (ii) debt securities of CF Industries (Other Debt Securities), and guarantees thereof by Parent and the Subsidiary Guarantors, that may be offered and sold from time to time under registration statements that may be filed by Parent, CF Industries and the Subsidiary Guarantors with the SEC. In the event that a subsidiary of Parent, other than CF Industries, becomes a borrower or a guarantor under the Revolving Credit Agreement (or any renewal, replacement or refinancing thereof), such subsidiary would be required to become a guarantor of the Public Senior Notes, provided that such requirement will no longer apply with respect to the Public Senior Notes due 2023, 2034, 2043 and 2044 following the repayment of the Public Senior Notes due 2020 or the subsidiaries of Parent, other than CF Industries, otherwise becoming no longer subject to such a requirement to guarantee the Public Senior Notes due 2020. The Subsidiary Guarantors became guarantors of the Public Senior Notes as a result of this requirement. All of the guarantees of the Public Senior Notes are, and we have assumed for purposes of this presentation of condensed consolidating financial information that the guarantees of any Other Debt Securities would be, full and unconditional (as such term is defined in SEC Regulation S-X Rule 3-10(h)) and joint and several. The guarantee of a Subsidiary Guarantor will be automatically released with respect to a series of the Public Senior Notes (1) upon the release, discharge or termination of such Subsidiary Guarantor’s guarantee of the Revolving Credit Agreement (or any renewal, replacement or refinancing thereof), (2) upon legal defeasance with respect to the Public Senior Notes of such series or satisfaction and discharge of the indenture with respect to such series of Public Senior Notes or (3) in the case of the Public Senior Notes due 2023, 2034, 2043 and 2044, upon the discharge, termination or release of, or the release of such Subsidiary Guarantor from its obligations under, such Subsidiary Guarantor’s guarantee of the Public Senior Notes due 2020, including, without limitation, any such discharge, termination or release as a result of retirement, discharge or legal or covenant defeasance of, or satisfaction and discharge of the supplemental indenture governing, the Public Senior Notes due 2020. For purposes of the presentation of condensed consolidating financial information, the subsidiaries of Parent other than CF Industries and the Subsidiary Guarantors are referred to as the Non-Guarantors. Presented below are condensed consolidating statements of operations for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors for the three months ended March 31, 2018 and 2017 , condensed consolidating statements of cash flows for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors for the three months ended March 31, 2018 and 2017 , and condensed consolidating balance sheets for Parent, CF Industries, the Subsidiary Guarantors and the Non-Guarantors as of March 31, 2018 and December 31, 2017 . The condensed consolidating financial information presented below is not necessarily indicative of the financial position, results of operations, comprehensive income (loss) or cash flows of Parent, CF Industries, the Subsidiary Guarantors or the Non-Guarantors on a stand-alone basis. In these condensed consolidating financial statements, investments in subsidiaries are presented under the equity method, in which our investments are recorded at cost and adjusted for our ownership share of a subsidiary’s cumulative results of operations, distributions and other equity changes, and the eliminating entries reflect primarily intercompany transactions such as sales, accounts receivable and accounts payable and the elimination of equity investments and earnings of subsidiaries. As of March 31, 2018, two of our consolidated entities have made elections to be taxed as partnerships for U.S. federal income tax purposes and are included in the non-guarantor column. Due to the partnership tax treatment, these subsidiaries do not record taxes on their financial statements. The tax provision pertaining to the income of these partnerships, plus applicable deferred tax balances are reflected on the financial statements of the parent company owner that is included in the subsidiary guarantors column in the following financial information. Liabilities related to benefit plan obligations are reflected on the legal entity that funds the obligation, while the benefit plan expense is included on the legal entity to which the employee provides services.

Subsequent Events [Abstract]
Subsequent Event [Text Block]	19 . Subsequent Event On February 7, 2018, we announced that, in accordance with the terms of the TNCLP Agreement of Limited Partnership, TNGP, the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP (the Public Units). The purchase price of $84.033 per Public Unit was determined under the terms of TNCLP’s Agreement of Limited Partnership as the average of the daily closing prices per common unit for the 20 consecutive trading days beginning with January 5, 2018 and ending with February 2, 2018. TNGP completed its purchase of the Public Units on April 2, 2018 (the Purchase) for an aggregate cash purchase price of $388 million . We funded the Purchase with cash on hand. As a result of the Purchase, all rights of the holders of the Public Units have ceased, except for the right to receive payment of the purchase price, and the common units representing limited partner interests are no longer publicly traded or listed on the New York Stock Exchange. Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP.

New Accounting Standards (Polic

New Accounting Standards (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Recently Adopted Pronouncements	Recently Adopted Pronouncements On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments. Additionally, the costs to obtain and fulfill a contract, including assets to be recognized, are to be capitalized and such capitalized costs should be disclosed. In 2016, the Financial Accounting Standards Board (FASB) issued additional ASUs that enhanced the operability of the principal versus agent guidance in ASU No. 2014-09 by clarifying that an entity should consider the nature of each good or service promised to a customer at the individual good or service level, clarified that ASU No. 2014-09 should not be applied to immaterial performance obligations, and enhanced the guidance around the treatment of shipping costs incurred to fulfill performance obligations. Our adoption of this ASU, utilizing the modified retrospective approach on contracts that were not completed as of January 1, 2018, resulted in a reduction to opening retained earnings of $1 million related to the cumulative difference between ASC 605 and ASC 606. See Note 3—Revenue Recognition for additional information. On January 1, 2018, we adopted ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities, which changes the income statement impact of equity investments held by an entity. The amendments require the unrealized gains or unrealized losses of equity instruments measured at fair value to be recognized in net income. Our adoption of this ASU resulted in an increase to opening retained earnings of $1 million representing the cumulative effect of unrealized gains from equity securities from accumulated other comprehensive income (loss). On January 1, 2018, we adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash - a consensus of the FASB Emerging Issues Task Force, which requires that the statement of cash flows include amounts described as restricted cash and restricted cash equivalents as part of cash and cash equivalents when reconciling the beginning and ending period total amounts. Upon adoption of this ASU, $1 million of withdrawals from restricted cash funds previously reflected as cash provided by investing activities for the three months ended March 31, 2017, and our restricted cash of $5 million and $4 million as of December 31, 2016 and March 31, 2017, respectively, were reclassified to be included within the reconciliation of beginning and ending cash, cash equivalents and restricted cash balances on our consolidated statement of cash flows. On January 1, 2018, we adopted ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changed the presentation of net benefit cost related to employer sponsored defined benefit plans and other postretirement benefits. Only service cost can be included within the same income statement line item as other compensation costs arising from services rendered during the period, while other components of net benefit cost must be presented separately outside of operating income. Additionally, only service costs may be capitalized on the balance sheet. Our adoption of this ASU was applied retrospectively for the income statement classification requirements and prospectively for the capitalization guidance, which resulted in $1 million of net benefit cost previously recognized in cost of sales to be reclassifed to other non-operating on our consolidated statement of operations for the three months ended March 31, 2017. On January 1, 2018, we adopted ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Our adoption of this ASU had no impact on our consolidated financial statements. Recently Issued Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in ASC Topic 840, Leases. This ASU will require lessees to recognize the rights and obligations resulting from virtually all leases (other than leases that meet the definition of a short-term lease) on their balance sheets as right-of-use assets with corresponding lease liabilities. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of income and expense recognized and expected to be recognized from existing contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and requires the modified retrospective method of adoption. While we are continuing to evaluate the impact of the adoption of this ASU on our consolidated financial statements, we currently believe the most significant change relates to the recognition of the right-of-use assets and lease liabilities on our balance sheet for operating leases for certain property and equipment, including transportation equipment utilized for the distribution of our products. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships in order to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, and should be applied to existing hedging relationships as of the date of adoption. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and for interim periods therein. Early adoption of this ASU is permitted. We do not expect the adoption of this ASU will have a material effect on our consolidated financial statements.
Revenue Recognition	In situations where we have agreed to arrange delivery of the product to the customer’s intended destination and control of the product transfers upon loading of our product onto transportation equipment, we have elected to account for any freight income associated with the delivery of these products as freight revenue, since this activity fulfills our obligation to transfer the product to the customer.
