Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Business	Organization and Nature of Business The Mosaic Company (“ Mosaic , ” and, with its consolidated subsidiaries, “ we , ” “ us , ” “ our , ” or the “ Company ”) produces and markets concentrated phosphate and potash crop nutrients. We conduct our business through wholly and majority owned subsidiaries and businesses in which we own less than a majority or a non-controlling interest, including consolidated variable interest entities and investments accounted for by the equity method. We are organized into the following business segments: • Our Phosphate business segment owns and operates mines and production facilities in Florida which produce concentrated phosphate crop nutrients and phosphate-based animal feed ingredients, and processing plants in Louisiana which produce concentrated phosphate crop nutrients. The Phosphate segment includes our 75% interest in the Miski Mayo Phosphate Mine (“ Miski Mayo ”) in Peru. These results are consolidated in the Phosphate segment. The Phosphate segment also includes our 25% interest in the Ma’aden Wa’ad Al Shamal Phosphate Company (“ MWSPC ”), a joint venture to develop, own and operate integrated phosphate production facilities in the Kingdom of Saudi Arabia. We market approximately 25% of MWSPC phosphate production. We recognize our equity in the net earnings or losses relating to MWSPC on a one-quarter lag in our Condensed Consolidated Statements of Earnings. • Our Potash business segment owns and operates potash mines and production facilities in Canada and the U.S. which produce potash-based crop nutrients, animal feed ingredients and industrial products. Potash sales include domestic and international sales. We are a member of Canpotex, Limited (“ Canpotex ”), an export association of Canadian potash producers through which we sell our Canadian potash outside the U.S. and Canada. • Our Mosaic Fertilizantes business segment includes the assets in Brazil that we acquired in the 2018 acquisition (the “ Acquisition ”) of Vale Fertilizantes S.A. (now known as Mosaic Fertilizantes P&K S.A.), which consist of five phosphate rock mines, four phosphate chemical plants and a potash mine. The segment also includes our legacy distribution business in South America, which consists of sales offices, crop nutrient blending and bagging facilities, port terminals and warehouses in Brazil and Paraguay. We also have a majority interest in Fospar S.A., which owns and operates a single superphosphate granulation plant and a deep-water port and throughput warehouse terminal facility in Brazil. Intersegment eliminations, unrealized mark-to-market gains/losses on derivatives, debt expenses, and the results of the China and India distribution businesses are included within Corporate, Eliminations and Other.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Statement Presentation and Basis of Consolidation The accompanying unaudited Condensed Consolidated Financial Statements of Mosaic have been prepared on the accrual basis of accounting and in accordance with the requirements of the Securities and Exchange Commission (“ SEC ”) for interim financial reporting. As permitted under these rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States (“ GAAP ”) can be condensed or omitted. The Condensed Consolidated Financial Statements included in this document reflect, in the opinion of our management, all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of the results for the interim periods presented. The following notes should be read in conjunction with the accounting policies and other disclosures in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2022 (the “ 10-K Report ”). Sales, expenses, cash flows, assets and liabilities can and do vary during the year as a result of seasonality and other factors. Therefore, interim results are not necessarily indicative of the results to be expected for the full fiscal year. The accompanying Condensed Consolidated Financial Statements include the accounts of Mosaic, its majority owned subsidiaries, and certain variable interest entities in which Mosaic is the primary beneficiary. Certain investments in companies where we do not have control but have the ability to exercise significant influence are accounted for by the equity method. Accounting Estimates Preparation of the Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. The most significant estimates made by management relate to the estimates of fair value of acquired assets and liabilities, the recoverability of non-current assets including goodwill, the useful lives and net realizable values of long-lived assets, environmental and reclamation liabilities, including asset retirement obligations (“ ARO ”), and income tax-related accounts, including the valuation allowance against deferred income tax assets. Actual results could differ from these estimates.

Earnings Per Share	Sep. 30, 2023
Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The numerator for basic and diluted earnings per share (“ EPS ”) is net earnings attributable to Mosaic. The denominator for basic EPS is the weighted average number of shares outstanding during the period. The denominator for diluted EPS also includes the weighted average number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued, unless the shares are anti-dilutive. The following is a reconciliation of the numerator and denominator for the basic and diluted EPS computations: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Net income (loss) attributable to Mosaic $ (4.2) $ 841.7 $ 799.6 $ 3,059.6 Basic weighted average number of shares outstanding 331.5 344.2 333.0 356.5 Dilutive impact of share-based awards — 3.5 2.1 3.6 Diluted weighted average number of shares outstanding 331.5 347.7 335.1 360.1 Basic net income (loss) per share attributable to Mosaic $ (0.01) $ 2.45 $ 2.40 $ 8.58 Diluted net income (loss) per share attributable to Mosaic $ (0.01) $ 2.42 $ 2.39 $ 8.50 A total of 0.6 million and 0.4 million shares of common stock subject to issuance related to share-based awards for the three and nine months ended September 30, 2023, respectively, and 0.1 million for the three and nine months ended September 30, 2022 have been excluded from the calculation of diluted EPS because the effect would have been anti-dilutive.

Investments, Debt and Equity Securities [Abstract]
Marketable Securities Held in Trusts	Marketable Securities Held in Trusts In August 2016, Mosaic deposited $630 million into two trust funds (together, the “ RCRA Trusts ”) created to provide additional financial assurance in the form of cash for the estimated costs (“ Gypstack Closure Costs ”) of closure and long-term care of our Florida and Louisiana phosphogypsum management systems (“ Gypstacks ”), as described further in Note 10 of our Notes to Condensed Consolidated Financial Statements. Our actual Gypstack Closure Costs are generally expected to be paid by us in the normal course of our Phosphate business; however, funds held in each of the RCRA Trusts can be drawn by the applicable governmental authority in the event we cannot perform our closure and long-term care obligations. When our estimated Gypstack Closure Costs with respect to the facilities associated with a RCRA Trust are sufficiently lower than the amount on deposit in that RCRA Trust, we have the right to request that the excess funds be released to us. The same is true for the RCRA Trust balance remaining after the completion of our obligations, which will be performed over a period that may not end until three decades or more after a Gypstack has been closed. The investments held by the RCRA Trusts are managed by independent investment managers with discretion to buy, sell and invest pursuant to the objectives and standards set forth in the related trust agreements. Amounts reserved to be held or held in the RCRA Trusts (including losses or reinvested earnings) are included in other assets on our Condensed Consolidated Balance Sheets. The RCRA Trusts hold investments, which are restricted from our general use, in marketable debt securities classified as available-for-sale and are carried at fair value. As a result, unrealized gains and losses are included in other comprehensive income until realized, unless it is determined that the entire unamortized cost basis of the investment is not expected to be recovered. A credit loss would then be recognized in operations for the amount of the expected credit loss. As of September 30, 2023, we expect to recover our amortized cost on all available-for-sale securities and have not established an allowance for credit loss. We review the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. We determine the fair market values of our available-for-sale securities and certain other assets based on the fair value hierarchy described below: Level 1: Values based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2: Values based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or model-based valuation techniques for which all significant assumptions are observable in the market. Level 3: Values generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. The estimated fair value of the investments in the RCRA Trusts as of September 30, 2023 and December 31, 2022 are as follows: September 30, 2023 Amortized Gross Gross Fair Level 1 Cash and cash equivalents $ (0.2) $ — $ — $ (0.2) Level 2 Corporate debt securities 205.1 — (15.4) 189.7 Municipal bonds 207.2 — (10.8) 196.4 U.S. government bonds 272.2 — (9.1) 263.1 Total $ 684.3 $ — $ (35.3) $ 649.0 December 31, 2022 Amortized Gross Gross Fair Level 1 Cash and cash equivalents $ 7.7 $ — $ — $ 7.7 Level 2 Corporate debt securities 203.8 0.1 (17.1) 186.8 Municipal bonds 197.0 0.4 (8.0) 189.4 U.S. government bonds 269.6 — (3.6) 266.0 Other holdings 0.2 — — 0.2 Total $ 678.3 $ 0.5 $ (28.7) $ 650.1 The following tables show gross unrealized losses and fair values of the RCRA Trusts ’ available-for-sale securities that have been in a continuous unrealized loss position for which an allowance for credit losses has not been recorded as of September 30, 2023 and December 31, 2022 : September 30, 2023 December 31, 2022 (in millions) Fair Gross Fair Gross Securities that have been in a continuous loss position for less than 12 months: Corporate debt securities $ 62.1 $ (1.9) $ 105.6 $ (6.5) Municipal bonds 102.1 (3.3) 104.7 (2.9) U.S. government bonds 262.3 (9.1) 264.9 (3.5) $ 426.5 $ (14.3) $ 475.2 $ (12.9) Securities that have been in a continuous loss position for more than 12 months: Corporate debt securities $ 124.4 $ (13.5) $ 72.8 $ (10.6) Municipal bonds 91.3 (7.5) 61.9 (5.1) U.S. government bonds — — 0.8 (0.1) $ 215.7 $ (21.0) $ 135.5 $ (15.8) The following table summarizes the balance by contractual maturity of the available-for-sale debt securities invested by the RCRA Trusts as of September 30, 2023.

Financing Arrangements [Abstract]
Debt Disclosure	Financing Arrangements Inventory Financing Arrangement We have an inventory financing arrangement whereby we can sell up to $625 million of certain inventory for cash and subsequently repurchase the inventory at an agreed upon price and time in the future, not to exceed 180 days. Under the terms of the agreement, we may borrow up to 90% of the value of the inventory. It is later repurchased by Mosaic at the original sale price plus interest and any transaction costs. As of September 30, 2023 and December 31, 2022, there was no outstanding balance under this facility. Receivable Purchasing Arrangement We finance certain accounts receivable through a Receivable Purchasing Agreement (“ RPA ”) with banks whereby, from time-to-time, we sell the receivables. The net face value of the purchased receivables may not exceed $600 million at any point in time. The purchase price of the receivable sold under the RPA is the face value of the receivable less an agreed upon discount. The receivables sold under the RPA are accounted for as a true sale. Upon sale, these receivables are removed from the Condensed Consolidated Balance Sheets. Cash received is presented as cash provided by operating activities in the Condensed Consolidated Statements of Cash Flows. During the three and nine months ended September 30, 2023, the Company sold approximately $115.4 million and $1.2 billion, respectively, of accounts receivable under this arrangement. During the three and nine months ended September 30, 2022, the Company sold approximately $1.0 billion and $1.6 billion, respectively. Discounts on sold receivables were not material for any period presented. Following the sale to the banks, we continue to service the collection of the receivables on behalf of the banks without further consideration. As of September 30, 2023 and December 31, 2022, there were no amounts outstanding to be remitted to the bank. Any outstanding amount would be classified in accrued liabilities on the Condensed Consolidated Balance Sheets. Cash collected and remitted are presented as cash used in financing activities in the Condensed Consolidated Statements of Cash Flows. Structured Accounts Payable Arrangements In Brazil, we finance some of our potash-based fertilizer, sulfur, ammonia and other raw material product purchases through third-party contractual arrangements. These arrangements provide that the third-party intermediary advance the amount of the scheduled payment to the vendor, less an appropriate discount, at a scheduled payment date. Mosaic then makes payment to the third-party intermediary at dates ranging from 98 to 180 days from date of shipment. As of September 30, 2023 and December 31, 2022, the total structured accounts payable arrangements were $600.6 million and $751.2 million, respectively. Commercial Paper Note Program In September 2022, we established a commercial paper program which allows us to issue unsecured commercial paper notes with maturities that vary, but do not exceed 397 days from the date of issue, up to a maximum aggregate face or principal amount outstanding at any time of $2.5 billion. We plan to use the revolving credit facility as a liquidity backstop for borrowings under the commercial paper program. As of September 30, 2023, we had $299.6 million outstanding under this program, with a weighted average interest rate of 5.52% and remaining average term of 10 days. As of December 31, 2022, we had $224.8 million outstanding under this program, with a weighted average interest rate of 4.66% and a remaining average term of 10 days. Term Loan Facility In May 2023, we entered into a 10-year senior unsecured term loan facility whereby we can draw up to $700 million. The term loan matures on May 18, 2033. We may voluntarily prepay the outstanding principal without premium or penalty. As of September 30, 2023, no amounts have been drawn under this facility.

Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligation Disclosure	Asset Retirement Obligations We recognize our estimated AROs in the period in which we have an existing legal obligation associated with the retirement of a tangible long-lived asset, and the amount of the liability can be reasonably estimated. The ARO is recognized at fair value when the liability is incurred with a corresponding increase in the carrying amount of the related long-lived asset. We depreciate the tangible asset over its estimated useful life. The liability is adjusted in subsequent periods through accretion expense, which represents the increase in the present value of the liability due to the passage of time. Such depreciation and accretion expenses are included in cost of goods sold for operating facilities and other operating expense for indefinitely closed facilities. Our legal obligations related to asset retirement require us to: (i) reclaim lands disturbed by mining as a condition to receive permits to mine phosphate ore reserves; (ii) treat low pH process water in Gypstacks to neutralize acidity; (iii) close and monitor Gypstacks at our Florida and Louisiana facilities at the end of their useful lives; (iv) remediate certain other conditional obligations; (v) remove all surface structures and equipment, plug and abandon mine shafts, contour and revegetate, as necessary, and monitor for five years after closing our Carlsbad, New Mexico facility; (vi) decommission facilities, manage tailings and execute site reclamation at our Saskatchewan potash mines at the end of their useful lives; (vii) de-commission mines in Brazil and Peru; and (viii) decommission plant sites and close Gypstacks in Brazil. The estimated liability for these legal obligations is based on the estimated cost to satisfy the above obligations, which is discounted using a credit-adjusted risk-free rate. A reconciliation of our AROs is as follows: (in millions) September 30, 2023 December 31, 2022 AROs, beginning of period $ 1,905.6 $ 1,749.3 Liabilities incurred 15.2 14.9 Liabilities settled (147.5) (205.6) Accretion expense 70.0 81.6 Revisions in estimated cash flows 293.7 264.5 Foreign currency translation 9.2 0.9 AROs, end of period 2,146.2 1,905.6 Less current portion 392.1 212.3 Non-current portion of AROs $ 1,754.1 $ 1,693.3 North America Gypstack Closure Costs A majority of our ARO relates to Gypstack Closure Costs in Florida and Louisiana. For financial reporting purposes, we recognize our estimated Gypstack Closure Costs at their present value. This present value determined for financial reporting purposes is reflected on our Consolidated Balance Sheets in accrued liabilities and other non-current liabilities. As discussed below, we have arrangements to provide financial assurance for the estimated Gypstack Closure Costs associated with our facilities in Florida and Louisiana. EPA RCRA Initiative. On September 30, 2015, we and our subsidiary, Mosaic Fertilizer, LLC (“ Mosaic Fertilizer ”), reached agreements with the U.S. Environmental Protection Agency (“ EPA ”), the U.S. Department of Justice (“ DOJ ”), the Florida Department of Environmental Protection (“ FDEP ”) and the Louisiana Department of Environmental Quality on the terms of two consent decrees (collectively, the “ 2015 Consent Decrees ”) to resolve claims relating to our management of certain waste materials onsite at our Riverview, New Wales, Green Bay, South Pierce and Bartow fertilizer manufacturing facilities in Florida and our Faustina and Uncle Sam facilities in Louisiana. This followed a 2003 announcement by the EPA Office of Enforcement and Compliance Assurance that it would be targeting facilities in mineral processing industries, including phosphoric acid producers, for a thorough review under the U.S. Resource Conservation and Recovery Act (“ RCRA ”) and related state laws. As discussed below, a separate consent decree was previously entered into with the EPA and the FDEP with respect to RCRA compliance at the Plant City, Florida phosphate concentrates facility (the “ Plant City Facility ”) that we acquired as part of our acquisition (the “ CF Phosphate Assets Acquisition ”) of the Florida phosphate assets and assumption of certain related liabilities of CF Industries, Inc. (“ CF ”). The remaining monetary obligations under the 2015 Consent Decrees include: • Modification of certain operating practices and undertaking certain capital improvement projects over a period of several years that are expected to result in remaining capital expenditures likely to exceed $20 million in the aggregate. • Provision of additional financial assurance for the estimated Gypstack Closure Costs for Gypstacks at the covered facilities. The RCRA Trusts are discussed in Note 8 to our Condensed Consolidated Financial Statements. In addition, we have agreed to guarantee the difference between the amounts held in each RCRA Trust (including any earnings) and the estimated closure and long-term care costs. As of December 31, 2022, the undiscounted amount of our Gypstack Closure Costs ARO associated with the facilities covered by the 2015 Consent Decrees, determined using the assumptions used for financial reporting purposes, was approximately $2.1 billion, and the present value of our Gypstack Closure Costs ARO reflected in our Consolidated Balance Sheet for those facilities was approximately $692.3 million. Plant City and Bonnie Facilities. As part of the CF Phosphate Assets Acquisition, we assumed certain AROs related to Gypstack Closure Costs at both the Plant City Facility and a closed Florida phosphate concentrates facility in Bartow, Florida (the “ Bonnie Facility ”) that we acquired. Associated with these assets are two related financial assurance arrangements for which we became responsible and that provided sources of funds for the estimated Gypstack Closure Costs for these facilities. Pursuant to federal or state laws, the applicable government entities are permitted to draw against such amounts in the event we cannot perform such closure activities. One of the financial assurance arrangements was initially a trust (the “ Plant City Trust ”) established to meet the requirements under a consent decree with the EPA and the FDEP with respect to RCRA compliance at Plant City. The Plant City Trust also satisfied Florida financial assurance requirements at that site. Beginning in September 2016, as a substitute for the financial assurance provided through the Plant City Trust, we have provided financial assurance for the Plant City Facility in the form of a surety bond (the “ Plant City Bond ”). The amount of the Plant City Bond is $300.8 million, which reflects our closure cost estimates as of December 31, 2022. The other financial assurance arrangement was also a trust fund (the “ Bonnie Facility Trust ”) established to meet the requirements under Florida financial assurance regulations that apply to the Bonnie Facility. In July 2018, we received $21.0 million from the Bonnie Facility Trust by substituting for the trust fund a financial test mechanism (“ Bonnie Financial Test ”) supported by a corporate guarantee as allowed by state regulations. Both financial assurance funding obligations require estimates of future expenditures that could be impacted by refinements in scope, technological developments, new information, cost inflation, changes in regulations, discount rates and the timing of activities. Under our current approach to satisfying applicable requirements, additional financial assurance would be required in the future if increases in cost estimates exceed the face amount of the Plant City Bond or the amount supported by the Bonnie Financial Test. As of September 30, 2023 and December 31, 2022, the aggregate amounts of AROs associated with the combined Plant City Facility and Bonnie Facility Gypstack closure costs included in our Condensed Consolidated Balance Sheets were $365.3 million and $327.5 million, respectively. The aggregate amount represented by the Plant City Bond exceeds the present value of the aggregate amount of ARO associated with that facility. This is because the amount of financial assurance we are required to provide represents the aggregate undiscounted estimated amount to be paid by us in the normal course of our Phosphate business over a period that may not end until three decades or more after the Gypstack has been closed, whereas the ARO included in our Condensed Consolidated Balance Sheet reflects the discounted present value of those estimated amounts.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the nine months ended September 30, 2023, gross unrecognized tax benefits increased by $0.1 million to $25.5 million. The increase is primarily related to recording reserves offset by settlements which occurred during the period. If recognized, approximately $25.0 million in unrecognized tax benefits would affect our effective tax rate and net earnings in future periods. We recognize interest and penalties related to unrecognized tax benefits as a component of our income tax provision. We had accrued interest and penalties totaling $5.7 million and $5.0 million as of September 30, 2023 and December 31, 2022, respectively, that were included in other noncurrent liabilities in the Condensed Consolidated Balance Sheets. Accounting for uncertain tax positions is determined by prescribing the minimum probability threshold that a tax position is more likely than not to be sustained based on the technical merits of the position. Mosaic is continually under audit by various authorities in the normal course of business. Such tax authorities may raise issues contrary to positions taken by the Company. If such positions are ultimately not sustained by the Company, this could result in material assessments to the Company. The costs related to defending, if needed, such positions on appeal or in court may be material. The Company believes that any issues raised have been properly accounted for in its current financial statements. For the three months ended September 30, 2023, discrete tax items recorded in tax expense was a benefit of approximately $17.3 million. The net tax benefit consisted primarily of the true up of estimates from our U.S. tax return provision and other miscellaneous costs. In addition to items specific to the period, our income tax rate is impacted by the mix of earnings across the jurisdictions in which we operate, by a benefit associated with depletion, a benefit associated with non-U.S. incentives, changes in valuation allowances, withholding tax expense and by the impact of certain entities being taxed in both their foreign jurisdiction and the U.S., including foreign tax credits for various taxes incurred.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Accounting for Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We periodically enter into derivatives to mitigate our exposure to foreign currency risks, interest rate movements and the effects of changing commodity prices. We record all derivatives on the Condensed Consolidated Balance Sheets at fair value. The fair value of these instruments is determined by using quoted market prices, third-party comparables or internal estimates. We net our derivative asset and liability positions when we have a master netting arrangement in place. Changes in the fair value of the foreign currency, commodity and freight derivatives are immediately recognized in earnings. We do not apply hedge accounting treatments to our foreign currency exchange contracts, commodities contracts or freight contracts. Unrealized gains and losses on foreign currency exchange contracts used to hedge cash flows related to the production of our products are included in cost of goods sold in the Condensed Consolidated Statements of Earnings. Unrealized gains and losses on commodities contracts and certain forward freight agreements are also recorded in cost of goods sold in the Condensed Consolidated Statements of Earnings. Unrealized gains or losses on foreign currency exchange contracts used to hedge cash flows that are not related to the production of our products are included in the foreign currency transaction gain/loss caption in the Condensed Consolidated Statements of Earnings. From time to time, we enter into fixed-to-floating interest rate contracts. We apply fair value hedge accounting treatment to these contracts. Under these arrangements, we agree to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. The mark-to-market of these fair value hedges is recorded as gains or losses in interest expense. We had no fixed-to-floating interest rate swap agreements in effect as of September 30, 2023 and December 31, 2022. As of September 30, 2023 and December 31, 2022, the gross asset position of our derivative instruments was $9.5 million and $38.8 million, respectively, and the gross liability position of our liability instruments was $31.1 million and $50.1 million, respectively. As of September 30, 2023 and December 31, 2022, the following is the total absolute notional volume associated with our outstanding derivative instruments: (in millions of Units) September 30, 2023 December 31, 2022 Derivative Instrument Derivative Category Unit of Measure Foreign currency derivatives Foreign currency US Dollars 2,577.6 2,361.1 Natural gas derivatives Commodity MMbtu 16.4 14.2 Credit-Risk-Related Contingent Features Certain of our derivative instruments contain provisions that are governed by International Swap and Derivatives Association agreements with the counterparties. These agreements contain provisions that allow us to settle for the net amount between payments and receipts, and also state that if our debt were to be rated below investment grade, certain counterparties could request full collateralization on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position as of September 30, 2023 and December 31, 2022 was $20.3 million and $34.8 million, respectively. We have no cash collateral posted in association with these contracts. If the credit-risk-related contingent features underlying these agreements were triggered on September 30, 2023, we would have been required to post an additional $16.4 million of collateral assets, which are either cash or U.S. Treasury instruments, to the counterparties. Counterparty Credit Risk We enter into foreign exchange, certain commodity and interest rate derivatives, primarily with a diversified group of highly rated counterparties. We continually monitor our positions and the credit ratings of the counterparties involved and limit the amount of credit exposure to any one party. While we may be exposed to potential losses due to the credit risk of non-performance by these counterparties, material losses are not anticipated. We closely monitor the credit risk associated with our counterparties and customers and to date have not experienced material losses.

Fair Value Measurements	Sep. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Following is a summary of the valuation techniques for assets and liabilities recorded in our Condensed Consolidated Balance Sheets at fair value on a recurring basis: Foreign Currency Derivatives - The foreign currency derivative instruments that we currently use are forward contracts, which typically expire within 18 months. Most of the valuations are adjusted by a forward yield curve or interest rates. In such cases, these derivative contracts are classified within Level 2. Some valuations are based on exchange-quoted prices, which are classified as Level 1. Changes in the fair market values of these contracts are recognized in the Condensed Consolidated Financial Statements as a component of cost of goods sold in our Corporate, Eliminations and Other segment, or foreign currency transaction (gain) loss. As of September 30, 2023 and December 31, 2022, the gross asset position of our foreign currency derivative instruments was $6.9 million and $20.7 million, respectively, and the gross liability position of our foreign currency derivative instruments was $29.7 million and $49.2 million, respectively. Commodity Derivatives - The commodity contracts primarily relate to natural gas. The commodity derivative instruments that we currently use are forward purchase contracts and swaps. The natural gas contracts settle using NYMEX futures or AECO price indexes, which represent fair value at any given time. The contracts’ maturities and settlements are scheduled for future months and settlements are scheduled to coincide with anticipated gas purchases during those future periods. Quoted market prices from NYMEX and AECO are used to determine the fair value of these instruments. These market prices are adjusted by a forward yield curve and are classified within Level 2. Changes in the fair market values of these contracts are recognized in the Condensed Consolidated Financial Statements as a component of cost of goods sold in our Corporate, Eliminations and Other segment. As of September 30, 2023 and December 31, 2022, the gross asset position of our commodity derivative instruments was $2.6 million and $18.1 million, respectively, and the gross liability position of our commodity instruments was $1.4 million and $0.9 million, respectively. Interest Rate Derivatives - We manage interest expense through interest rate contracts to convert a portion of our fixed-rate debt into floating-rate debt. From time to time, we also enter into interest rate swap agreements to hedge our exposure to changes in future interest rates related to anticipated debt issuances. Valuations are based on external pricing sources and are classified as Level 2. Changes in the fair market values of these contracts are recognized in the Condensed Consolidated Financial Statements as a component of interest expense. We did not hold any interest rate derivative positions as of September 30, 2023. Financial Instruments The carrying amounts and estimated fair values of our financial instruments are as follows: September 30, 2023 December 31, 2022 Carrying Amount Fair Value Carrying Amount Fair Value Cash and cash equivalents $ 591.0 $ 591.0 $ 735.4 $ 735.4 Accounts receivable 1,399.2 1,399.2 1,699.9 1,699.9 Accounts payable 1,105.7 1,105.7 1,292.5 1,292.5 Structured accounts payable arrangements 600.6 600.6 751.2 751.2 Short-term debt 299.8 299.8 224.9 224.9 Long-term debt, including current portion 3,356.8 3,167.0 3,397.2 3,276.5 For cash and cash equivalents, accounts receivables, accounts payable, structured accounts payable arrangements and short-term debt, the carrying amount approximates fair value because of the short-term maturity of those instruments. The fair value of long-term debt, including the current portion, is estimated using quoted market prices for the publicly registered notes and debentures, classified as Level 1 and Level 2, respectively, within the fair value hierarchy, depending on the market liquidity of the debt.

Contingencies

Contingencies	9 Months Ended
Contingencies	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies We have described below material judicial and administrative proceedings to which we are subject. Environmental Matters We have contingent environmental liabilities that arise principally from three sources: (i) facilities currently or formerly owned by our subsidiaries or their predecessors; (ii) facilities adjacent to currently or formerly owned facilities; and (iii) third-party Superfund or state equivalent sites. At facilities currently or formerly owned by our subsidiaries or their predecessors, the historical use and handling of regulated chemical substances, crop and animal nutrients and additives and by-product or process tailings have resulted in soil, surface water and/or groundwater contamination. Spills or other releases of regulated substances, subsidence from mining operations and other incidents arising out of operations, including accidents, have occurred previously at these facilities, and potentially could occur in the future, possibly requiring us to undertake or fund cleanup or result in monetary damage awards, fines, penalties, other liabilities, injunctions or other court or administrative rulings. In some instances, pursuant to consent orders or agreements with governmental agencies, we are undertaking certain remedial actions or investigations to determine whether remedial action may be required to address contamination. At other locations, we have entered into consent orders or agreements with appropriate governmental agencies to perform required remedial activities that will address identified site conditions. Taking into consideration established accruals of approximately $144.2 million and $185.5 million as of September 30, 2023 and December 31, 2022, respectively, expenditures for these known conditions currently are not expected, individually or in the aggregate, to have a material effect on our business or financial condition. However, material expenditures could be required in the future to remediate the contamination at known sites or at other current or former sites or as a result of other environmental, health and safety matters. Below is a discussion of the more significant environmental matters. New Wales Phase II East Stack. In April 2022, we confirmed the presence of a cavity in and liner tear beneath the southern part of the active phosphogypsum stack at the Company’s New Wales facility in Florida. This resulted in process water draining beneath the stack. The circumstances were reported to the FDEP and the EPA. Phase I of the repairs, consisting of stabilizing the cavity by depositing low pressure grout into it, began in July 2022 and now is complete. Phase II work, which consists of injecting high pressure grout beneath the stack to restore the geological confining layer beneath it, began in early in 2023 and now is expected to conclude in the first quarter of 2024. As of September 30, 2023, we have a reserve of $36.3 million for the estimated repairs. We are unable to estimate at this time potential future additional financial impacts or a range of loss, if any, due to the ongoing evaluation. EPA RCRA Initiative. We have certain financial assurance and other obligations under consent decrees and a separate financial assurance arrangement relating to our facilities in Florida and Louisiana. These obligations are discussed in Note 14 of our Notes to Consolidated Financial Statements in our 10-K Report. Other Environmental Matters. Superfund and equivalent state statutes impose liability without regard to fault or to the legality of a party’s conduct on certain categories of persons who are considered to have contributed to the release of “hazardous substances” into the environment. Under Superfund, or its various state analogues, one party may, under certain circumstances, be required to bear more than its proportionate share of cleanup costs at a site where it has liability if payments cannot be obtained from other responsible parties. Currently, certain of our subsidiaries are involved or concluding involvement at several Superfund or equivalent state sites. Our remedial liability from these sites, alone or in the aggregate, currently is not expected to have a material effect on our business or financial condition. As more information is obtained regarding these sites and the potentially responsible parties involved, this expectation could change. We believe that, pursuant to several indemnification agreements, our subsidiaries are entitled to at least partial, and in many instances complete, indemnification for the costs that may be expended by us or our subsidiaries to remedy environmental issues at certain facilities. These agreements address issues that resulted from activities occurring prior to our acquisition of facilities or businesses from parties including, but not limited to: ARCO (BP); Beatrice Fund for Environmental Liabilities; Conoco; Conserv; Estech, Inc.; Kaiser Aluminum & Chemical Corporation; Kerr-McGee Inc.; PPG Industries, Inc.; The Williams Companies; CF; and certain other private parties. Our subsidiaries have already received and anticipate receiving amounts pursuant to the indemnification agreements for certain of their expenses incurred to date as well as future anticipated expenditures. We record potential indemnifications as an offset to the established accruals when they are realizable or realized. The failure of an indemnitor to fulfill its obligations could result in future costs that could be material. Louisiana Parishes Coastal Zone Cases Several Louisiana parishes and the City of New Orleans have filed lawsuits against hundreds of oil and gas companies seeking regulatory, restoration and compensatory damages in connection with historical oil, gas and sulfur mining and transportation operations in the coastal zone of Louisiana. Mosaic is the corporate successor to certain companies which performed these types of operations in the coastal zone of Louisiana. Mosaic has been named in two of the lawsuits filed to date. In addition, in several other cases, historical oil, gas and sulfur operations which may have been related to Mosaic’s corporate predecessors have been identified in the complaints. Based upon information known to date, Mosaic has contractual indemnification rights against third parties for any loss or liability arising out of these claims pursuant to indemnification agreements entered into by Mosaic’s corporate predecessor(s) with third parties. There may also be insurance contracts which may respond to some or all of the claims. However, the financial ability of the third-party indemnitors, the extent of potential insurance coverage and the extent of potential liability from these claims is currently unknown. As of October 2022, a memorandum of understanding has been executed by the State of Louisiana and the plaintiff parishes that filed claims against Mosaic and its corporate predecessors on one hand, and Mosaic Global Holdings Inc. and its third-party indemnitors on the other hand which, when fully implemented, will release and dismiss Mosaic and its corporate predecessors from the coastal zone cases. Funding obligations in the memorandum of understanding are expected to be undertaken by third-party indemnitors and/or insurers. Brazil Legal Contingencies Our Brazilian subsidiaries are engaged in a number of judicial and administrative proceedings regarding labor, environmental, mining and civil claims that allege aggregate damages and/or fines of approximately $695.4 million. We estimate that our probable aggregate loss with respect to these claims is approximately $76.8 million, which is included in our accrued liabilities in our Condensed Consolidated Balance Sheets at September 30, 2023. Approximately $507.2 million of the foregoing maximum potential loss relates to labor claims, of which approximately $65.4 million is included in accrued liabilities in our Condensed Consolidated Balance Sheets at September 30, 2023. Based on Brazil legislation and the current status of similar labor cases involving unrelated companies, we believe we have recorded adequate loss contingency reserves sufficient to cover our estimate of probable losses. If the status of similar cases involving unrelated companies were to adversely change in the future, our maximum exposure could increase and additional accruals could be required. Brazil Tax Contingencies Our Brazilian subsidiaries are engaged in a number of judicial and administrative proceedings relating to various non-income tax matters. We estimate that our maximum potential liability with respect to these matters is approximately $606.9 million, of which $215.1 million is subject to an indemnification agreement entered into with Vale S.A in connection with the Acquisition. Approximately $381.9 million of the maximum potential liability relates to a Brazilian federal value added tax, PIS and COFINS and tax credit cases, while the majority of the remaining amount relates to various other non-income tax cases. The maximum potential liability can increase with new audits from Brazilian tax authorities. Based on Brazil tax legislation and the current status of similar tax cases involving unrelated taxpayers, we believe we have recorded adequate loss contingency reserves sufficient to cover our estimate of probable losses, which are immaterial. If the status of similar tax cases involving unrelated taxpayer changes in the future, additional accruals could be required. Other Claims We also have certain other contingent liabilities with respect to judicial, administrative and arbitration proceedings and claims of third parties, including tax matters, arising in the ordinary course of business. We do not believe that any of these contingent liabilities will have a material adverse impact on our business or financial condition, results of operations and cash flows.

Segment Reporting Disclosure	Business Segments The reportable segments are determined by management based upon factors such as products and services, production processes, technologies, market dynamics and for which segment financial information is available for our chief operating decision maker. We evaluate performance based on the operating earnings of the respective business segments, which includes certain allocations of corporate selling, general and administrative expenses. The segment results may not represent the actual results that would be expected if they were independent, stand-alone businesses. Intersegment eliminations, including profit on intersegment sales, mark-to-market gains/losses on derivatives, debt expenses and the results of the China and India distribution businesses are included within Corporate, Eliminations and Other.

Share Repurchases [Abstract]
Stockholders' Equity Note Disclosure	Share Repurchases In 2022, our Board of Directors approved two share repurchase programs for a total of $3.0 billion. Our repurchase programs allow the Company to repurchase shares of our Common Stock through open market purchases, accelerated share repurchase arrangements, privately negotiated transactions or otherwise, and have no set expiration date. On February 24, 2023, pursuant to existing stock repurchase authorizations, we entered into an accelerated share repurchase agreement (the “ 2023 ASR Agreement ”) with a third-party financial institution to repurchase $300 million of our Common Stock. At inception, we paid the financial institution $300 million and took initial delivery of 4,659,290 shares of our Common Stock, representing an estimated 80% of the total shares expected to be delivered under the 2023 ASR Agreement. In March 2023, the transaction was completed and we received an additional 965,284 shares of Common Stock. In total, 5,624,574 shares were delivered under the 2023 ASR Agreement, at an average purchase price of $53.34 per share. During the three and nine months ended September 30, 2023, we repurchased 3,948,783 and 12,639,719 shares of Common Stock in the open market for approximately $150.0 million and $598.0 million, respectively. This includes the 5,624,574 shares purchased under the 2023 ASR Agreement. On February 24, 2022, pursuant to existing stock repurchase authorizations, we entered into an accelerated share repurchase (the “ 2022 ASR Agreement ”) agreement with a third-party financial institution to repurchase $400 million of our Common Stock. At inception, we paid the financial institution $400 million and took initial delivery of 7,056,229 shares of our Common Stock. Under the terms of the 2022 ASR Agreement, upon settlement, we would either receive additional shares from the financial institution or be required to deliver additional shares or cash to the financial institution. In the second quarter of 2022, the 2022 ASR Agreement was completed and we paid the financial institution an additional $54.2 million. When combining the initial $400 million paid at the inception of the 2022 ASR Agreement and the cash settlement of $54.2 million at the termination of the 2022 ASR Agreement, we repurchased approximately 7,056,229 shares at an average repurchase price of $64.37 per share. During the three and nine months ended September 30, 2022, we repurchased 11,666,578 and 29,400,562 shares of Common Stock in the open market for approximately $574.8 million and $1.6 billion, respectively. This includes 7,056,229 shares purchased under the 2022 ASR agreement. The extent to which we repurchase our shares and the timing of any such repurchases depend on a number of factors, including market and business conditions, the price of our shares, our ability to access capital resources liquidity and corporate, regulatory and other considerations.

Accounting Policies [Abstract]
Basis of Consolidation	Statement Presentation and Basis of Consolidation The accompanying unaudited Condensed Consolidated Financial Statements of Mosaic have been prepared on the accrual basis of accounting and in accordance with the requirements of the Securities and Exchange Commission (“ SEC ”) for interim financial reporting. As permitted under these rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States (“ GAAP ”) can be condensed or omitted. The Condensed Consolidated Financial Statements included in this document reflect, in the opinion of our management, all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of the results for the interim periods presented. The following notes should be read in conjunction with the accounting policies and other disclosures in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2022 (the “ 10-K Report ”). Sales, expenses, cash flows, assets and liabilities can and do vary during the year as a result of seasonality and other factors. Therefore, interim results are not necessarily indicative of the results to be expected for the full fiscal year.
Accounting Estimates	Accounting Estimates Preparation of the Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. The most significant estimates made by management relate to the estimates of fair value of acquired assets and liabilities, the recoverability of non-current assets including goodwill, the useful lives and net realizable values of long-lived assets, environmental and reclamation liabilities, including asset retirement obligations (“ ARO
