NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Tables in millions, except per share amounts and as otherwise designated)

(Unaudited)

1. 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 Phosphates 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. As part of the Acquisition, we acquired an additional 40% economic interest in the Miski Mayo Phosphate Mine in Peru, which increased our aggregate interest to 75%. These results are consolidated in the Phosphates segment. The Phosphates segment also includes our 25% interest in the Ma’aden Wa’ad Al Shamal Phosphate Company (the “MWSPC”), a joint venture to develop, own and operate integrated phosphate production facilities in the Kingdom of Saudi Arabia. We market approximately 25% of the 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 (Loss).

•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 acquisition (the “Acquisition”) of Vale Fertilizantes S.A. (now known as Mosaic Fertilizantes P&K S.A. or the “Acquired Business”), 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 crop nutrition port and throughput warehouse terminal facility in Brazil.

Intersegment eliminations, unrealized mark-to-market gains/losses on derivatives, debt expenses, Streamsong Resort® results of operations, and the results of the China and India distribution businesses are included within Corporate, Eliminations and Other.

2. 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, 2020 (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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

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.

(a) The timing of recognition of revenue related to our performance obligations may be different than the timing of collection of cash related to those performance obligations. Specifically, we collect prepayments from certain customers in Brazil. In addition, cash collection from Canpotex may occur prior to delivery of product to the end customer. We generally satisfy our contractual liabilities within one quarter of incurring the liability.

4. 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 March 31,
	2021		2020
Net income (loss) attributable to Mosaic	$	156.7	$	(203.0)
Basic weighted average number of shares outstanding	379.2		378.8
Dilutive impact of share-based awards	3.6		—
Diluted weighted average number of shares outstanding	382.8		378.8
Basic net income (loss) per share attributable to Mosaic	$	0.41	$	(0.54)
Diluted net income (loss) per share attributable to Mosaic	$	0.41	$	(0.54)

A total of 0.7 million and 2.5 million shares of common stock subject to issuance related to share-based awards for the three months ended March 31, 2021 and March 31, 2020, respectively, have been excluded from the calculation of diluted EPS because the effect would have been anti-dilutive.

5. Inventories

Inventories consist of the following:

	March 31, 2021		December 31, 2020
Raw materials	$	138.6	$	92.1
Work in process	637.1		634.5
Finished goods	938.7		868.2
Final price deferred(a)	21.0		23.0
Operating materials and supplies	125.3		121.4
	$	1,860.7	$	1,739.2

______________________________

(a)Final price deferred is product that has shipped to customers, but the price has not yet been agreed upon.

6. Goodwill

Mosaic had goodwill of $1.2 billion as of March 31, 2021 and December 31, 2020, respectively. We review goodwill for impairment annually in October and at any time events or circumstances indicate that the carrying value may not be fully

10

Table of Contents
	THE MOSAIC COMPANY
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

recoverable, which is based on our accounting policy and GAAP. The changes in the carrying amount of goodwill, by reporting unit, are as follows:

	Potash		Mosaic Fertilizantes		Corporate, Eliminations and Other		Total
Balance as of December 31, 2020	$	1,063.2	$	97.7	$	12.1	$	1,173.0
Foreign currency translation	9.2		(2.2)		—		7.0
Balance as of March 31, 2021	$	1,072.4	$	95.5	$	12.1	$	1,180.0

We are required to perform our next annual goodwill impairment analysis as of October 31, 2021. It is possible that, during the remainder of 2021 or beyond, business conditions could deteriorate from the current state, raw material or product price projections could decline significantly from current estimates, or our common stock price could decline significantly. If projected net sales and cash flow projections are not achieved or our common stock price significantly declines from current levels, book values of certain operations could exceed their fair values, which may result in goodwill impairment charges in future periods. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

7. 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 9 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 carrying value of an investment is impaired on an other-than-temporary basis.

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:

8. Financing Arrangements

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 financing 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 and Mosaic makes payment to the third-party intermediary at a later date, stipulated in accordance with the commercial terms negotiated. As of March 31, 2021 and December 31, 2020, the total structured accounts payable arrangements were $797.5 million and $640.0 million, respectively.

13

Table of Contents
	THE MOSAIC COMPANY
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Receivable Purchasing Arrangement

On March 4, 2020, we entered into a Receivable Purchasing Agreement (“RPA”), with a bank whereby, from time-to-time, we sell certain receivables. The net face value of the purchased receivables may not exceed $150 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. As of December 31, 2020, there was no outstanding balance under this facility. In January 2021, we entered into a First Amendment to the RPA. This amendment made certain adjustments so that the receivables sold under the RPA will be 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. Prior to the amendment, we recorded the purchase price as short-term debt, and recognized interest expense by accreting the liability through the due date of the underlying receivables.

During the three months ended March 31, 2021 and 2020, the Company sold approximately $86.6 million and $101.5 million, respectively, of accounts receivable under this arrangement. Discounts on sold receivables were not material for any period presented. Following the sale to the bank, we continue to service the collection of the receivable on behalf of the bank without further consideration. As of March 31, 2021, $86.6 million had been collected but not yet remitted to the bank. This amount is classified in accrued liabilities on the Condensed Consolidated Balance Sheets. Cash collected and remitted are presented as financing activities in the Condensed Consolidated Statements of Cash Flows.

9. 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 acquired as part of the Acquisition and (viii) decommission plant sites and close Gypstacks in Brazil, also as part of the Acquisition. 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)	March 31, 2021		December 31, 2020
AROs, beginning of period	$	1,393.9	$	1,315.2
Liabilities incurred	4.7		10.8

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, Mulberry, 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 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 7 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, 2020, 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 $1.6 billion, and the present value of our Gypstack Closure Costs ARO reflected in our Consolidated Balance Sheet for those facilities was approximately $439.1 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 $243.2 million, which reflects our closure cost estimates as of December 31, 2020. 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

15

Table of Contents
	THE MOSAIC COMPANY
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

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 March 31, 2021 and December 31, 2020, 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 $247.9 million and $251.8 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 Phosphates 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.

10. Income Taxes

During the three months ended March 31, 2021, gross unrecognized tax benefits increased by $0.6 million to $37.5 million. The increase is primarily related to recording non-U.S. reserves and foreign exchange. If recognized, approximately $20.3 million of the $37.5 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 $9.4 million and $9.0 million as of March 31, 2021 and December 31, 2020, 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 tax 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 is currently in negotiations with non-U.S. tax authorities where settlements could result in different tax outcomes than what is currently accounted for. The Company believes that any issues raised have been properly accounted for.

For the three months ended March 31, 2021, tax expense specific to the period was a cost of approximately $4.4 million. This consisted primarily of tax cost of $2.3 million recorded related to non-U.S. prior year adjustments, $2.0 million related to the write-off of expired stock options, and other miscellaneous costs of $0.1 million. 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, by a benefit associated with non-U.S. incentives, by changes in valuation allowances 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.

Generally, for interim periods, income tax is equal to the total of (1) year-to-date pretax income multiplied by our forecasted effective tax rate plus (2) tax expense items specific to the period. In situations where we expect to report losses for which we do not expect to receive tax benefits, we are required to apply separate forecasted effective tax rates to those jurisdictions rather than including them in the consolidated effective tax rate. For the three months ended March 31, 2021, income tax expense was not impacted by this set of rules.

For the three months ended March 31, 2020, tax expense specific to the period was a benefit of approximately $28.3 million. This consisted primarily of tax benefit of $25.1 million recorded related to the impacts of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to prior years. The CARES Act provides various tax relief measures to taxpayers impacted by the coronavirus. Tax expense specific to the period also included a benefit of $5.5 million related to release of the sequestration on AMT, which was partially offset by a share-based excess cost of $1.7 million and changes in estimates related to prior years of $0.6 million. 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, and by the impact of certain entities being taxed in both foreign jurisdictions and the U.S., including foreign tax credits for various taxes incurred.

11. 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

16

Table of Contents
	THE MOSAIC COMPANY
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

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 March 31, 2021 and December 31, 2020.

As of March 31, 2021 and December 31, 2020, the gross asset position of our derivative instruments was $61.5 million and $65.3 million, respectively, and the gross liability position of our liability instruments was $37.8 million and $49.9 million, respectively.

As of March 31, 2021 and December 31, 2020, the following is the total absolute notional volume associated with our outstanding derivative instruments:

(in millions of Units)			March 31, 2021	December 31, 2020
Derivative Instrument	Derivative Category	Unit of Measure
Foreign currency derivatives	Foreign currency	US Dollars	2,399.2	2,912.3
Natural gas derivatives	Commodity	MMbtu	34.1	27.3

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 March 31, 2021 and December 31, 2020, was $12.8 million and $11.3 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 March 31, 2021, we would have been required to post an additional $8.3 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.

12. 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 and zero-cost collars, which typically expire within eighteen 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 March 31, 2021 and December 31, 2020, the gross asset position of our foreign currency derivative instruments was $53.3 million and $58.6 million, respectively, and the gross liability position of our foreign currency derivative instruments was $36.9 million and $48.7 million, respectively.

Commodity Derivatives - The commodity contracts primarily relate to natural gas. The commodity derivative instruments that we currently use are forward purchase contracts, swaps, and three-way collars. 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 March 31, 2021 and December 31, 2020, the gross asset position of our commodity derivative instruments was $8.2 million and $6.7 million, respectively, and the gross liability position of our commodity instruments was $0.9 million and $1.2 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. In April 2020, we terminated our outstanding interest rate swap contracts which resulted in an immaterial impact to our Condensed Consolidated Statement of Earnings (Loss).

Financial Instruments

The carrying amounts and estimated fair values of our financial instruments are as follows:

	March 31, 2021				December 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Cash and cash equivalents	$	692.0	$	692.0	$	574.0	$	574.0
Accounts receivable	851.6		851.6		881.1		881.1
Accounts payable	762.3		762.3		769.1		769.1
Structured accounts payable arrangements	797.5		797.5		640.0		640.0
Short-term debt	15.1		15.1		0.1		0.1
Long-term debt, including current portion	4,469.5		4,950.8		4,578.0		5,172.1

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.

In 2015, we agreed to provide funds to finance the purchase and construction of two articulated tug and barge units, intended to transport anhydrous ammonia for our operations, through a bridge loan agreement with Gulf Marine Solutions, LLC (“GMS”). GMS is a wholly owned subsidiary of Gulf Sulphur Services Ltd., LLLP (“Gulf Sulphur Services”), an entity in which we and a joint venture partner, Savage Companies (“Savage”), each indirectly own a 50% equity interest and for which a subsidiary of Savage provides operating and management services. GMS provided these funds through draws on the Mosaic bridge loan and through additional loans from Gulf Sulphur Services. We are the primary beneficiary of GMS, a variable interest entity, and consolidate GMS’s operations in our Phosphates segment.

On October 24, 2017, a lease financing transaction was completed with respect to the completed tug and barge unit, and, following the application of proceeds from the transaction, all outstanding loans made by Gulf Sulphur Services to GMS, together with accrued interest, were repaid, and the bridge loans related to the first unit’s construction were repaid. As of March 31, 2021 and December 31, 2020, there were outstanding bridge loans of $74.7 million relating to the cancelled second barge and the remaining tug, which bridge loans are eliminated in consolidation. Reserves against the bridge loans of approximately $54.2 million were established in 2018 and remain unchanged. Several subsidiaries of Savage operate vessels utilized by Mosaic under time charter arrangements, including the ammonia tug and barge unit.

15. 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 $56.4 million and $61.4 million as of March 31, 2021 and December 31, 2020, 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 Water Loss Incident. In August 2016, a sinkhole developed under one of the two cells of the active Gypstack at our New Wales facility in Polk County, Florida, resulting in process water from the stack draining into the sinkhole. The incident was reported to the FDEP and EPA. In October 2016, our subsidiary, Mosaic Fertilizer, entered into a consent order (the “Order”) with the FDEP relating to the incident. Under the Order, Mosaic Fertilizer agreed to, among other things: implement a remediation plan to close the sinkhole; perform additional monitoring of the groundwater quality and act to assess and remediate in the event monitored off-site water does not comply with applicable standards as a result of the incident; evaluate the risk of potential future sinkhole formation at the New Wales facility and at Mosaic Fertilizer’s active Gypstack operations at the Bartow, Riverview and Plant City facilities and provide recommendations to address any identified issues; and provide financial assurance of no less than $40.0 million, which we have done without the need for any expenditure of corporate funds through satisfaction of a financial strength test and Mosaic parent guarantee. The Order did not require payment of civil penalties relating to the incident.

As of March 31, 2021, the sinkhole repairs were substantially complete. Additional expenditures could be required in the future for additional remediation or other measures in connection with the sinkhole including if, for example, FDEP or EPA were to request additional measures to address risks presented by the Gypstack. These expenditures could be material. In addition, we

are unable to predict at this time what, if any, impact the New Wales water loss incident will have on future Florida permitting efforts.

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 9 of our Notes to Condensed Consolidated Financial Statements.

Florida Sulfuric Acid Plants. On April 8, 2010, EPA Region 4 submitted an administrative subpoena to us under Section 114 of the Federal Clean Air Act (the “CAA”) regarding compliance of our Florida sulfuric acid plants with the “New Source Review” requirements of the CAA. The request received by Mosaic appears to be part of a broader EPA national enforcement initiative focusing on sulfuric acid plants. On June 6, 2010, EPA issued a notice of violation to CF (the “CF NOV”) with respect to “New Source Review” compliance at the Plant City Facility's sulfuric acid plants and the allegations in the CF NOV were not resolved before our 2014 acquisition of the Plant City Facility. CF has agreed to indemnify us with respect to any penalty EPA may assess as a result of the allegations in the CF NOV.

We have been engaged in settlement discussions with U.S. EPA and the Department of Justice, originating with the allegations of violations of Clean Air Act Prevention of Significant Deterioration (“PSD”) permitting requirements at the Plant City sulfuric acid plants and encompassing injunctive relief regarding sulfur dioxide emissions across Mosaic’s Florida sulfuric acid plant fleet. With the closure of Plant City fertilizer operations, there is no longer a need to reach resolution with the government on injunctive relief (i.e., reduction of sulfur dioxide emissions) at that facility. Furthermore, the Department of Justice has determined that there is no basis for proceeding with a settlement, as EPA and the Department have not currently alleged any violations of the Clean Air Act PSD permitting requirements at any other of Mosaic’s Florida sulfuric acid plants.

We cannot predict at this time whether EPA and DOJ will initiate an enforcement action in the future with respect to “New Source Review” compliance at our Florida sulfuric acid plants or what its scope would be, or what the range of outcomes might be with respect to such a potential enforcement action.

Uncle Sam Gypstack. In January 2019, we observed lateral movement of the north slope of our active phosphogypsum stack at the Uncle Sam facility in Louisiana. The observation was reported to the Louisiana Department of Environmental Quality and the U.S. EPA. We continue to provide updates to the agencies on the movement, which has slowed following actions we have taken, which include reducing process water volume stored atop the stack to reduce the active load causing the movement; constructing a stability berm at the base of the slope to increase resistance; and removing gypsum from the north side to the south side. These steps have improved slope stability, reduced slope movement and reduced our capacity to store process water. There has been no loss of containment resulting from the movement observed, and none is expected. Although continued lateral movement on the north slope could have a material effect on our future operations at that facility, we cannot predict the prospective impact on our results of operations at this time.

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.

In September 2019, counsel for several of the parishes announced that an agreement had been reached to settle the claims against Mosaic and its corporate predecessors, subject to approval by the participating parishes and the State of Louisiana. In connection with that settlement agreement, the proposed settlement payment obligations would be paid by third-party indemnitors.

Phosphate Mine Permitting in Florida

Denial of the permits sought at any of our mines, issuance of the permits with cost-prohibitive conditions, substantial delays in issuing the permits, legal actions that prevent us from relying on permits or revocation of permits may create challenges for us to mine the phosphate rock required to operate our Florida and Louisiana phosphate plants at desired levels or increase our costs in the future.

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 $748 million. We estimate that our probable aggregate loss with respect to these claims is approximately $57.5 million, which is included in our accrued liabilities in our Condensed Consolidated Balance Sheet as of March 31, 2021.

Approximately $596.5 million of the maximum potential loss relates to labor claims, such as in-house and third-party employees’ judicial proceedings alleging the right to receive overtime pay, additional payment due to work in hazardous conditions, risk premium, profit sharing, additional payment due to night work, salary parity and wage differences. We estimate that our probable aggregate loss regarding these claims is approximately $51.4 million, which has been accrued as of March 31, 2021.

Based on Brazilian 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.

The environmental judicial and administrative proceedings claims allege aggregate damages and/or fines in excess of $17.1 million; however, we estimate that our probable aggregate loss regarding these claims is approximately $4.4 million, which has been accrued as of March 31, 2021.

The mining judicial and administrative proceedings claims allege aggregate damages and/or fines of approximately $3.6 million. We estimate that our probable aggregate loss regarding these claims will be immaterial as of March 31, 2021.

Our Brazilian subsidiaries also have certain other civil contingent liabilities with respect to judicial, administrative and arbitration proceedings and claims related to contract disputes, pension plan matters, real state disputes, regulatory issues and other civil matters arising in the ordinary course of business. These claims allege aggregate damages in excess of $130.9 million. We estimate that the probable aggregate loss with respect to these matters is approximately $1.7 million.

Uberaba Judicial Settlement

In 2013, the Federal Public Prosecutor filed a public civil action requesting that the Company adopt several measures to mitigate soil and water contamination related to the Gypstack at our Uberaba facility, located in the State of Minas Gerais, including compensation for the alleged social and environmental damages. In 2014, our predecessor subsidiary in Brazil entered into a judicial settlement with the Federal Public Prosecutor, the State of Minas Gerais public prosecutor and the federal environmental agency. Under this agreement, we agreed to implement remediation measures such as: constructing a liner under the Gypstack water ponds and lagoons, and monitoring the groundwater and soil quality. We also agreed to create a private reserve of natural heritage and to pay compensation in the amount of approximately $0.3 million, which was paid in July 2018. We are currently acting in compliance with our obligations under the judicial settlement and expect them to be completed by December 31, 2023.

Uberaba EHS Class Action

In 2013, the State of Minas Gerais public prosecutor filed a class action claiming that our predecessor company in Brazil did not comply with labor safety rules and working hour laws. This claim was based on an inspection conducted by the Labor and Employment Ministry in 2010, following which we were fined for not complying with several labor regulations. We filed our defense, claiming that we complied with these labor regulations and that the assessment carried out by the inspectors in 2010 was abusive. Following the initial hearing, the court ordered an examination to determine whether there has been any non-compliance with labor regulations. The examination is currently pending and the parties are negotiating a settlement. The amount claimed in the proceeding is $27.5 million.

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 $331.2 million, of which $154.3 million is subject to an indemnification agreement entered into with Vale S.A in connection with the Acquisition.

Approximately $217.4 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. Based on Brazil 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.

16. 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, Streamsong Resort® results of operations and the results of the China and India distribution businesses are included within Corporate, Eliminations and Other. For a description of our business segments, see Note 1 to the Condensed Consolidated Financial Statements.

Overview of Consolidated Results for the three months ended March 31, 2021 and 2020

For the three months ended March 31, 2021, Mosaic had net income of $156.7 million, or $0.41 per diluted share, compared to a net loss of $(203.0) million, or $(0.54) per diluted share, for the prior year period. The current period results were negatively impacted by a total of $77 million pre-tax, or $0.16 per diluted share, related to the following notable items:

•Foreign currency transaction loss of $46 million, or $(0.09) per diluted share

27

•Depreciation expense of $22 million, or $(0.04) per diluted share, related to the acceleration of the closure of our K1 and K2 mine shafts at our Esterhazy, Saskatchewan mine as we ramp up K3

•Other operating expenses of $15 million, or $(0.03) per diluted share, related to maintaining closed and indefinitely idled facilities

•Other operating income of $11 million, or $0.02 per diluted share related to recovery of a reserve for the Acquired Business (as defined below)

•Unrealized loss on derivatives of $8 million, or $(0.02) per diluted share

•Discrete income tax expense of $4 million, or $(0.01) per diluted share

•Other non-operating income of $3 million, or $0.01 per diluted share, related to a realized gain on RCRA trust securities

During the three months ended March 31, 2020, our results included:

•Foreign currency transaction loss of $214 million, or $(0.38) per diluted share

•Unrealized loss on derivatives of $51 million, or $(0.09) per diluted share

•Depreciation expense of $22 million, or $(0.03) per diluted share, related to the acceleration of the closure of our K1 and K2 mine shafts at our Esterhazy, Saskatchewan mine as we ramp up K3

•Other operating expenses of $16 million, or $(0.04) per diluted share, related to maintaining closed and indefinitely idled facilities

•Other operating expenses of $9 million, or $(0.02) per diluted share, related to an increase in reserves for legal contingencies of the Acquired Business (as defined below)

•Idle plant costs of $5 million, or $(0.01) per diluted share, related to the government-mandated shutdown on March 16, 2020, of our Miski Mayo phosphate rock mine in Peru due to the COVID-19 outbreak

•Discrete income tax benefit of $28 million, or $0.08 per diluted share

•Other non-operating income of $5 million, or $0.01 per diluted share, related to a realized gain on RCRA trust securities

Significant factors affecting our results of operations and financial condition are listed below. Certain of these factors are discussed in more detail in the following sections of this Management’s Discussion and Analysis of Financial Condition and Results of Operations.

In addition to the items noted above, our operating results for the three months ended March 31, 2021 were favorably impacted in our Phosphates segment by significantly higher sales prices than the prior year period. Sales prices have continued to rise, after reaching a low in the first quarter of 2020, driven by tightness in global supply and demand, strong farmer economics and improved grain prices. The segment's operating results were also favorably impacted by higher sales volumes, driven by increased demand in North America, due to a strong spring season and decreased competitor shipments into North America. Competitor shipments were impacted by import duties against producers in Morocco and Russia, which resulted from the countervailing duty investigations into imports of phosphate fertilizers discussed further below. The benefit from higher sales prices and volumes was partially offset by higher raw material costs, primarily sulfur, in the current year period compared to the prior year. Availability of molten sulfur has been impacted by refinery closures in 2020 and 2021, due to lower fuel demand and extreme cold weather in the first quarter of 2021 in the southern United States, where several refineries are located. We expect availability to be tight throughout 2021, recovering as refinery performance improves.

Our operating results during the three months ended March 31, 2021, were favorably impacted in our Potash segment by higher sales volumes compared to the prior year period. Volumes were driven by strong global demand and strong farmer economics. Our Potash segment was also favorably impacted by higher average sales prices in North America. Prices began to strengthen in North America and Brazil in the fourth quarter of 2020, due to increased demand and tight supply. They have continued to increase in 2021, but have not yet returned to levels seen prior to 2020. This increase has been offset by a decrease in international sales prices.

For the three months ended March 31, 2021, operating results were favorably impacted by our Mosaic Fertilizantes segment. Sales prices increased compared to the same period in the prior year, due to the increase in global sales prices and strengthening

28

market conditions in Brazil, including strong farmer economics that were driven by improved commodity prices and weaker foreign currency rates.

Other Highlights

•In 2020, we filed petitions with the U.S. Department of Commerce (“DOC”) and the U.S. International Trade Commission (“ITC”) that requested the initiation of countervailing duty investigations into imports of phosphate fertilizers from Morocco and Russia. The purpose of the petitions was to remedy the distortions that we believe foreign subsidies have caused or are causing in the U.S. market for phosphate fertilizers, and thereby restore fair competition. On February 16, 2021, the DOC made final affirmative determinations that countervailable subsidies were being provided by those governments. On March 11, 2021, the ITC made final affirmative determinations that the U.S. phosphate fertilizer industry is materially injured by reason of subsidized phosphate fertilizer imports from Morocco and Russia. As a result of these determinations, the DOC issued countervailing duty orders on phosphate fertilizer imports from Russia and Morocco, which are scheduled to remain in place for at least five years. currently, the cash deposit rates for such imports are approximately 20 percent for Moroccan producer OCP, 9 percent and 47 percent for Russian producers PhosAgro and Eurochem, respectively, and 17 percent for all other Russian producers. The final determinations in the DOC and ITC investigations are subject to possible challenges before U.S. federal courts and the World Trade Organization, and Mosaic has initiated actions at the U.S. Court of International Trade contesting certain aspects of the DOC's final determinations that, we believe, failed to capture the full extent of Moroccan and Russian phosphate fertilizer subsidies. Further, the cash deposit rates and the amount of countervailing duties owed by importers on such imports could change based on the results of the DOC's annual administrative review proceedings.

•In March 2021, we announced an increase in our annual dividend target to $0.30 from $0.20 per share.

(a) Includes intersegment sales volumes.

(b) Includes sales volumes of MicroEssentials® and animal feed ingredients.

Three months ended March 31, 2021 and March 31, 2020

The Phosphates segment’s net sales were $1.0 billion for the three months ended March 31, 2021, compared to $0.6 billion for the three months ended March 31, 2020. The increase in net sales in the current year period was primarily due to favorable sales prices, which had an impact of approximately $300 million compared to the prior year period. Net sales were also favorably impacted in the current year by approximately $60 million due to increased sales volumes compared to the prior year period.

Our average finished product selling price increased 50% to $477 per tonne for the three months ended March 31, 2021, compared to $317 per tonne in the prior year period, due to the factors discussed in the Overview.

30

The Phosphates segment’s sales volumes of finished products increased by 7% for the three months ended March 31, 2021, compared to the same period in the prior year, due to the factors discussed in the Overview.

Gross margin for the Phosphates segment increased to $172.6 million for the three months ended March 31, 2021, from $(82.9) million for the three months ended March 31, 2020. The increase in gross margin in the current year period was primarily due to significantly higher sales prices, which favorably impacted gross margin by approximately $300 million, compared to the prior year period. This was partially offset by the unfavorable impact of approximately $40 million from increased raw material prices, largely driven by sulfur as discussed in the Overview.

The average consumed price for ammonia for our North American operations increased to $316 per tonne for the three months ended March 31, 2021, from $309 in the same period a year ago. We typically purchase approximately one-third of our ammonia from various suppliers in the spot market, with the remaining two-thirds either purchased through an ammonia supply agreement or produced internally at our Faustina, Louisiana location. The average consumed sulfur price for our North American operations increased by more than 50% to $119 per long ton for the three months ended March 31, 2021, from $78 in the same period a year ago. The purchase prices of these raw materials are driven by global supply and demand. The consumed ammonia and sulfur prices also include transportation, transformation, and storage costs.

The average consumed cost of purchased and produced phosphate rock decreased to $61 per tonne for the three months ended March 31, 2021, compared to $62 per tonne for the three months ended March 31, 2020. For the three months ended March 31, 2021, our North American phosphate rock production decreased to 3.0 million tonnes from 3.4 million tonnes for the same period of the prior year, due to operational challenges as we transitioned into new mining areas.

The Phosphates segment's production of crop nutrient dry concentrates and animal feed ingredients remained flat at 1.9 million tonnes for the three months ended March 31, 2021 and March 31, 2020. Production volume reflects turnaround activity during the current year period. As a result, we expect sales to remain constrained in the second quarter of 2021 due to limited inventory levels. Our operating rate for processed phosphate production increased to 77% for the three months ended March 31, 2021, from 75% for the same period in 2020.

(a) Includes intersegment sales volumes.

(b) Includes sales volumes of K-mag, Aspire and animal feed ingredients.

Three months ended March 31, 2021 and March 31, 2020

The Potash segment’s net sales increased to $477.4 million for the three months ended March 31, 2021, compared to $441.6 million in the same period a year ago. The increase was due to higher sales volumes, as a result of the factors described in the Overview. The higher sales volumes had a favorable impact on net sales of approximately $35 million.

Our average finished product selling price was $241 per tonne for the three months ended March 31, 2021, compared to $233 per tonne for the same period a year ago, as a result of the factors described in the Overview.

The Potash segment’s sales volumes of finished products increased to 2.0 million tonnes for the three months ended March 31, 2021, compared to 1.9 million tonnes in the same period a year ago.

Gross margin for the Potash segment increased to $140.2 million for the three months ended March 31, 2021, from $109.1 million in the same period of the prior year. The increase in gross margin in the current year period is primarily due to approximately $25 million of higher sales volumes, compared to the prior year period. In addition, the current year period was favorably impacted by approximately $5 million from lower fixed cost absorption, due to higher production, and lower brine inflow costs, partially offset by foreign currency impacts, compared to the prior year period.

We had expense of $35.0 million from Canadian resource taxes for the three months ended March 31, 2021, compared to $31.7 million in the same period a year ago. Canadian royalty expense increased to $8.5 million for the three months ended March 31, 2021, compared to $8.2 million for the three months ended March 31, 2020. The fluctuations in Canadian resource taxes are a result of an increase in sales volumes and margins, due to the factors discussed in the Overview. The increase in royalties is due to the increase in sales revenue.

We incurred $23 million in brine inflow management expenses, including depreciation on brine assets, at our Esterhazy mine during the three months ended March 31, 2021, compared to $33 million for the three months ended March 31, 2020. The reduced costs in 2021 are a reflection of our management of brine inflow expense and the accelerated closure of the K1 and K2 shafts at Esterhazy. We remain on track in our development of the K3 shaft at our Esterhazy mine, which is expected to reach full operational capacity by mid-2022. The completion of K3 will provide us the opportunity to eliminate future brine inflow management costs, which are expected to drop to an immaterial level by the end of 2021.

Our operating rate for potash production was 94% for the current year period, compared to 85% in the prior year period. The increased operating rate in the current year period reflects the need to meet strong demand.

______________________________

Three months ended March 31, 2021 and March 31, 2020

The Mosaic Fertilizantes segment’s net sales increased to $763.4 million for the three months ended March 31, 2021, from $731.1 million in the same period a year ago. The increase in net sales was due to higher sales prices, which favorably impacted net sales by approximately $30 million.

Our average finished product selling price was $370 per tonne for the three months ended March 31, 2021, compared to $352 per tonne for the same period a year ago, due to the increase in global sales prices, favorable market conditions and the mix of products sold.

The Mosaic Fertilizantes segment’s sales volumes of finished products decreased slightly for the three months ended March 31, 2021, compared to the same period a year ago.

Gross margin for the Mosaic Fertilizantes segment increased to $103.1 million for the three months ended March 31, 2021, from $66.5 million in the same period of the prior year. The increase in gross margin was primarily due to a favorable impact of approximately $60 million related to the increase in selling prices during the current year period compared to the prior year period. This was partially offset by an increase in raw material costs, primarily ammonia and sulfur, of approximately $20 million, compared to the prior year period. The purchase prices of these raw materials are driven by global supply and demand.

33

Gross margin was also negatively impacted by higher production costs of approximately $20 million in the current year period, due to inflationary pressure, higher maintenance costs and lower production volumes compared to the prior year period. In addition, gross margin was favorably impacted from foreign currency changes of approximately $15 in the current year period.

The Mosaic Fertilizantes segment's production of crop nutrient dry concentrates and animal feed ingredients decreased 7%, to 0.9 million tonnes, for the three months ended March 31, 2021, from 1.0 million tonnes in the prior year period. For the three months ended March 31, 2021, our operating rate decreased to 73%, compared to 77% in the same period of the prior year. Current year production was impacted by unplanned downtime and lower quality ore.

For the three months ended March 31, 2021, our Brazilian phosphate rock production increased to 1.1 million tonnes from 1.0 million tonnes in the prior year period. 

Corporate, Eliminations and Other

In addition to our three operating segments, we assign certain costs to Corporate, Eliminations and Other, which is presented separately in Note 16 to our Notes to Condensed Consolidated Financial Statements. Corporate, Eliminations and Other includes the results of the China and India distribution businesses, intersegment eliminations, including profit on intersegment sales, unrealized mark-to-market gains and losses on derivatives, debt expenses and Streamsong Resort® results of operations.

For the three months ended March 31, 2021, gross margin for Corporate, Eliminations and Other was $19.0 million, compared to a loss of $51.3 million for the same period in the prior year. The change was driven by distribution operations in India and China, which had revenue of $159.6 million and gross margin of $30.3 million in the current year period, compared to revenue of $76.5 million and gross margin of $2.0 million in the prior year period. The increases in revenue and gross margin during the current year period was due to an increase in sales volumes over the prior year period, primarily in China, due to strong demand and due high agriculture commodity prices. Gross margin was negatively impacted by a net unrealized loss of $8.1 million in the current year period, primarily on foreign currency derivatives, compared to a net unrealized loss of $50.8 million in the prior year period.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were $101.7 million for the three months ended March 31, 2021, compared to $67.9 million in the same period of the prior year. The increase was due to approximately $25 million of compensation expense related to long-term incentive awards in the current year period, partially offset by favorable foreign currency impacts of approximately $5 million, primarily driven by Brazil. The prior year included the reversal of stock compensation expense of approximately $14 million related to awards that did not meet performance hurdles for vesting.

34

Other Operating Expense

For the three months ended March 31, 2021, we had other operating expenses of $20.0 million, compared to $39.7 million for the same period in the prior year. The three months ended March 31, 2021 includes approximately $15 million related to maintaining closed and indefinitely idled facilities in our phosphates and potash operations. The current year period also includes income of approximately $11 million related to the recovery of a reserve for the Acquired Business.

Foreign Currency Transaction Gain (Loss)

We recorded a foreign currency transaction loss of $45.8 million for the three months ended March 31, 2021, compared to a loss of $214.2 million for the three months ended March 31, 2020. For the three months ended March 31, 2021, the loss was primarily the result of the effect of the strengthening of the U.S. dollar relative to the Brazilian real on significant U.S. dollar-denominated payables held by our Brazilian subsidiaries, partially offset by the weakening of the U.S. dollar relative to the Canadian dollar on significant U.S. dollar-denominated intercompany loans.

Equity in Net (Loss) Earnings of Nonconsolidated Companies

For the three months ended March 31, 2021, we had equity in net loss of nonconsolidated companies of $7.5 million, compared to equity in net loss of nonconsolidated companies of $20.0 million for the same period in the prior year. These losses are primarily related to operations at MWSPC.

Provision for (Benefit from) Income Taxes

Three months ended	Effective Tax Rate		Provision for (Benefit from) Income Taxes
March 31, 2021	26.5	%	$	59.7
March 31, 2020	42.0	%	$	(133.0)

Income tax expense was $59.7 million and the effective tax rate was 26.5% for the three months ended March 31, 2021.

For the three months ended March 31, 2021, tax expense specific to the period was a cost of approximately $4.4 million. This consisted primarily of tax cost of $2.3 million recorded related to non-U.S. prior year adjustments, $2.0 million related to the write-off of expired stock options, and other miscellaneous costs of $0.1 million. 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, by a benefit associated with non-U.S. incentives, by changes in valuation allowances 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.

For the three months ended March 31, 2020, tax expense specific to the period was a benefit of approximately $28.3 million. This consisted primarily of a tax benefit of $25.1 million recorded related to the impacts of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to prior years. The CARES Act provides various tax relief measures to taxpayers impacted by the coronavirus. Tax expense specific to the period also included a benefit of $5.5 million related to release of the sequestration on AMT, which was partially offset by a share-based excess cost of $1.7 million and changes in estimates related to prior years of $0.6 million. 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, and by the impact of certain entities being taxed in both foreign jurisdictions and the U.S., including foreign tax credits for various taxes incurred.

Critical Accounting Estimates

The Condensed Consolidated Financial Statements are prepared in conformity with GAAP. In preparing the Condensed Consolidated Financial Statements, we are required to make various judgments, estimates and assumptions that could have a significant impact on the results reported in the Condensed Consolidated Financial Statements. We base these estimates on historical experience and other assumptions believed to be reasonable by management under the circumstances. Changes in these estimates could have a material effect on our Condensed Consolidated Financial Statements.

35

The basis for our financial statement presentation, including our significant accounting estimates, is summarized in Note 2 to the Condensed Consolidated Financial Statements in this report. A summary description of our significant accounting policies is included in Note 2 to the Consolidated Financial Statements in our 10-K Report. Further detailed information regarding our critical accounting estimates is included in Management’s Discussion and Analysis of Results of Operations and Financial Condition in our 10-K Report.

Liquidity and Capital Resources

As of March 31, 2021, we had cash and cash equivalents of $0.7 billion, short-term debt of $15.1 million, long-term debt, including current maturities, of approximately $4.5 billion, and stockholders’ equity of approximately $9.8 billion. We have a target liquidity buffer of up to $3.0 billion, including cash and available committed and uncommitted credit lines. We expect our liquidity to fluctuate from time to time, especially in the first quarter of each year, to manage through the seasonality of our business. We also target debt leverage ratios that are consistent with investment grade credit metrics. Our capital allocation priorities include maintaining our target investment grade metrics and financial strength, sustaining our assets, including ensuring the safety and reliability of our assets, investing to grow our business, either through organic growth or taking advantage of strategic opportunities, and returning excess cash to shareholders, including paying our dividend. During the three months ended March 31, 2021, we invested $288.6 million in capital expenditures.

Funds generated by operating activities, available cash and cash equivalents, and our credit facilities continue to be our most significant sources of liquidity. We believe funds generated from the expected results of operations and available cash, cash equivalents and borrowings under our committed and uncommitted credit facilities, as needed, will be sufficient to finance our operations, including our capital expenditures, existing strategic initiatives and expected dividend payments, for the next 12 months. There can be no assurance, however, that we will continue to generate cash flows at or above current levels. As of March 31, 2021, we had $2.19 billion available under our $2.20 billion committed revolving credit facility and approximately $500 million available under uncommitted facilities. Our credit facilities, including the revolving credit facility and our term loans, require us to maintain certain financial ratios, as discussed in Note 10 of our Notes to Consolidated Financial Statements in our 10-K Report. We were in compliance with these ratios as of March 31, 2021.

All of our cash and cash equivalents are diversified in highly rated investment vehicles. Our cash and cash equivalents are held either in the U.S. or held by non-U.S. subsidiaries and are not subject to significant foreign currency exposures, as the majority are held in investments denominated in U.S. dollars as of March 31, 2021. These funds may create foreign currency transaction gains or losses, however, depending on the functional currency of the entity holding the cash. In addition, there are no significant restrictions that would preclude us from bringing these funds back to the U.S., aside from withholding taxes.

The following table represents a comparison of the net cash provided by operating activities, net cash used in investing activities, and net cash provided by financing activities for the three months ended March 31, 2021 and March 31, 2020:

(in millions)	Three months ended
	March 31, 2021				2021-2020
Cash Flow	2021		2020		Change		Percent
Net cash provided by operating activities	$	318.8	$	189.9	$	128.9	68	%
Net cash used in investing activities	(308.5)		(269.7)		(38.8)		14	%
Net cash provided by financing activities	121.7		698.3		(576.6)		(83)

Operating Activities

During the three months ended March 31, 2021, net cash provided by operating activities was $318.8 million, compared to $189.9 million for the three months ended March 31, 2020. Our results of operations, after non-cash adjustments to net earnings, contributed $401.8 million to cash flows from operating activities during the three months ended March 31, 2021, compared to a use of $183 million as computed on the same basis for the prior year period. During the three months ended March 31, 2021, we had an unfavorable working capital change of $83 million, compared to a favorable change of $6.9 million during the three months ended March 31, 2020.

36

The change in working capital for the three months ended March 31, 2021, was primarily driven by an increase in inventories of $180.7 million and an increase in accounts payable and accrued expenses of $64.6 million. The increase in inventories was primarily due to higher raw material costs and building inventory volumes, primarily in Brazil, as they prepare for their upcoming high season. The increase in accounts payable and accrued liabilities was primarily related an increase in customer prepayments in Brazil.

Investing Activities

Net cash used in investing activities was $308.5 million for the three months ended March 31, 2021, compared to $269.7 million for the same period a year ago. We had capital expenditures of $288.6 million for the three months ended March 31, 2021, compared to $263.5 million in the prior year period.

Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2021, was $121.7 million, compared to $698.3 million for the same period in the prior year. For the three months ended March 31, 2021, we had net proceeds from borrowings on short-term debt of $15.0 million, compared to net proceeds of $972.8 million in the prior year period, when we increased cash on hand in response to the economic uncertainty created by the Covid-19 outbreak. We had net proceeds from structured accounts payable of $153.7 million in the current year period, compared to net payments of $241.3 million in the prior year period. We also collected $86.6 million of receivables under the RPA agreement on behalf of the bank that had not yet been remitted to them. For the three months ended March 31, 2021, we made payments on long-term debt of 114.5 million and paid dividends of $18.9 million.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to the impact of fluctuations in the relative value of currencies, the impact of interest rates, fluctuations in the purchase price of natural gas, ammonia and sulfur consumed in operations, and changes in freight costs, as well as changes in the market value of our financial instruments. We periodically enter into derivatives in order to mitigate our foreign currency risks, interest rate risks and the effects of changing commodity prices, but not for speculative purposes. See Note 16 to the Consolidated Financial Statements in our 10-K Report and Note 11 to the Condensed Consolidated Financial Statements in this report.

Foreign Currency Exchange Contracts

Due to the global nature of our operations, we are exposed to currency exchange rate changes which may cause fluctuations in our earnings and cash flows. Our primary foreign currency exposures are the Canadian dollar and Brazilian real. To reduce economic risk and volatility on expected cash flows that are denominated in the Canadian dollar and Brazilian real, we use financial instruments that may include forward contracts, zero-cost collars and/or futures. Mosaic hedges cash flows on a declining basis, up to 18 months for the Canadian dollar and up to 12 months for the Brazilian real. We may enter into hedges of up to 36 months for expected Canadian dollar capital expenditures related to our Esterhazy K3 expansion program.

As of March 31, 2021, and December 31, 2020, the fair value of our major foreign currency exchange contracts was $16.5 million and $10.8 million, respectively. The table below provides information about Mosaic’s significant foreign exchange derivatives.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We have included information about legal and environmental proceedings in Note 15 to our Condensed Consolidated Financial Statements in this report. This information is incorporated herein by reference.

We are also subject to the following legal and environmental proceedings in addition to those described in Note 15 of our Condensed Consolidated Financial Statements in this report:

Waters of the United States. In June 2015, EPA and the U.S. Army Corps of Engineers (the “Corps”) jointly issued a final rule that proposed to clarify, but may actually expand, the scope of waters regulated under the federal Clean Water Act. The final rule (the “2015 Clean Water Rule”) became effective in August 2015, but has been challenged through numerous lawsuits. In October 2015, the U.S. Court of Appeals for the Sixth Circuit issued an order staying the effectiveness of the final rule nationwide pending adjudication of substantive challenges to the rule. In early 2017, the U.S. President issued an Executive Order directing EPA and the Corps to publish a proposed rule rescinding or revising the new rule. In June 2017, EPA and the Corps issued a proposed rule that would rescind the 2015 Clean Water Rule and re-codify regulatory text that existed prior to enactment of the 2015 Clean Water Rule. In November 2017, EPA issued a rule notice proposing to extend the applicability date of the 2015 Clean Water Rule for two years from the date of final action on the proposed rule, to provide continuity and regulatory certainty while agencies proceed to consider potential changes to the 2015 Clean Water Rule.

In January 2018, the U.S. Supreme Court unanimously held all challenges to the 2015 Clean Water Rule must be heard in federal district courts rather than in the federal courts of appeal, overruling a decision by the Sixth Circuit's Court of Appeals. With the Sixth Circuit Court of Appeals no longer having jurisdiction, that court lifted its 2015 nationwide stay in February 2018. After the nationwide stay was lifted, a number of U.S. District Courts revived dormant litigation that challenged the 2015 Clean Water Rule. In June 2018, the U.S. District Court for the Southern District of Georgia entered an injunction against implementation of the 2015 Clean Water Rule covering 11 states, including Florida. As of September 2018, federal district courts have put the 2015 Clean Water Rule on hold in 28 states, the District of Columbia and the U.S. territories.

On December 11, 2018, EPA and the Corps issued a proposed rule to replace the 2015 Clean Water Rule, referred to as the “Navigable Waters Protection Rule”. The agencies’ stated interpretation for the proposed rule is to provide clarity, predictability and consistency so that the regulated community can better understand where the Clean Water Act applies and where it does not. EPA and the Corps received over 600,000 public comments on the proposed rule.

On September 12, 2019, EPA and the Corps jointly issued a final regulation that repealed the 2015 Clean Water Rule and restored the previous regulatory regime. This regulation reestablished national consistency by returning all jurisdictions to the longstanding regulatory framework that existed prior to the 2015 Clean Water Rule. The final rule and repeal of the 2015 Clean Water Rule took effect sixty (60) days after publication in the Federal Register.

The September 12, 2019 repeal of the 2015 Clean Water Rule was the first step in a two-step rulemaking process to define the scope of “waters of the United States” that are regulated under the Clean Water Act. The second step was completed in April 2020, when EPA and the Corps jointly issued the “Navigable Waters Protection Rule” published on April 21, 2020 (85 Fed. Reg. 22,250). By defining what constitutes “waters of the United States” under the federal Clean Water Act (“CWA”), the new rule distinguishes between federal waters and waters under the sole control of the States. It also clarifies the types of connections to perennial and intermittent tributaries that make lakes and ponds jurisdictional and clarifies the factors that determine when wetlands are considered “adjacent”.

The new “Navigable Waters Protection Rule” revised the definition of “waters of the United States” (WOTUS) under the CWA to include: (i) territorial seas and traditional navigable waters; (ii) perennial and intermittent tributaries to those waters; (iii) certain lakes, ponds, and impoundments; (iv) and wetlands adjacent to jurisdictional waters. According to EPA, “Congress, in the Clean Water Act, explicitly directed the Agencies to protect ‘navigable waters.’ The Navigable Waters Protection Rule regulates the nation’s navigable waters and the core tributary systems that provide perennial or intermittent flow into them.”

45

The new Navigable Waters Protection Rule is in effect in every state except for Colorado. The U.S. District of Colorado blocked implementation of the Navigable Waters Protection Rule in Colorado, holding that the Supreme Court’s decision in Rapanos v.United States foreclosed the interpretation the U.S. EPA and Corps had incorporated into the new regulation. On the same day, the U.S. District Court for the Northern District of California reached the opposite conclusion, instead denying a motion by a group of states and cities to block the rule’s nationwide implementation. Similar requests for relief have been made in other federal district courts, including Arizona, Washington and New Mexico. To date, there have been 13 complaints filed in 11 different U.S. District Courts seeking to challenge final rule.

In August 2020, the Justice Department, an industry coalition, and individual landowners filed a Notice of Appeal with the U.S. Court of Appeals for the 10th Circuit to challenge the injunction entered by the Colorado District Court. (Note: Under the new Biden Administration, there could be administrative or legal actions that affect the future enforceability of the Navigable Waters Protection Rule, e.g. voluntary remand to reconsider the rule, issuance of an Executive Order directing EPA and Corps to reconsider the rule, or formal joint rulemaking to repeal Navigable Waters Protection Rule.)

On March 2, 2021, the 10th Circuit Court of Appeals determined that the district court abused its discretion when it granted the State of /Colorado's request to stay the effective date of the Navigable Waters Protection Rule in Colorado. In reversing and vacating the district court's decision, the court ruled that Colorado was not entitled to a preliminary injunction because it did not show it would suffer irreparable injury if the rule went into effect. As a result, the Navigable Waters Protection Rule remains in effect in all states.

Countervailing Duty Petitions. In 2020, we filed petitions with the U.S. Department of Commerce (“DOC”) and the U.S. International Trade Commission (“ITC”) that requested the initiation of countervailing duty investigations into imports of phosphate fertilizers from Morocco and Russia. The purpose of the petitions was to remedy the distortions that we believe foreign subsidies have caused or are causing in the U.S. market for phosphate fertilizers, and thereby restore fair competition. On February 16, 2021, the DOC made final affirmative determinations that countervailable subsidies were being provided by those governments. On March 11, 2021 the ITC made final affirmative determinations that the U.S. phosphate fertilizer industry is materially injured by reason of subsidized phosphate fertilizer imports from Morocco and Russia. As a result of these determinations, the DOC issued countervailing duty orders on phosphate fertilizer imports from Russia and Morocco, which are scheduled to remain in place for at least five years. Currently, the cash deposit rates for such imports are approximately 20 percent for Moroccan producer OCP, 9 percent and 47 percent for Russian producers PhosAgro and Eurochem, respectively, and 17 percent for all other /Russian producers. The final determinations in the DOC and ITC investigations are subject to possible challenges before U.S. federal courts and the World Trade Organization, and Mosaic has initiated actions at the U.S. Court of International Trade contesting certain aspects of the DOC's final determinations that, we believe, failed to capture the full extent of Moroccan and Russian phosphate fertilizer subsidies. Further, the cash deposit rates and the amount of countervailing duties owed by importers on such imports could change based on the results of the DOC's annual administrative review proceedings.

The South Pasture Extension Mine Litigation. On January 8, 2020, the Hardee County Mining Coordinator issued a Notice of Violation (“NOV”) for the failure by Mosaic to proceed with reclamation of two designated Reclamation Units within the South Pasture Mine footprint. These two Reclamation Units comprise 166 acres of mined lands. The NOV cites noncompliance with the County Land Development Regulations and with the conditions of Development of Regional Impact (“DRI”) Development Order 12-21 that was issued in 2012 to authorize continued mining at the South Pasture Mine, continued operation of the South Pasture beneficiation plant, and mining at the South Pasture Mine Extension. Through the NOV, the County requested that Mosaic submit a revised reclamation plan and schedule to demonstrate when initial reclamation activities would be completed for the two Reclamation Units identified in the NOV.

The delay in meeting the required reclamation schedule at the two Reclamation Units is tied to the idling and eventual shutdown of the Plant City fertilizer plant and the idling of the South Pasture Mine beneficiation plant. The Plant City facility was first idled in late 2017 and in June 2019, Mosaic announced that the Plant City facility would be closed permanently.

Given the relationship between the Plant City fertilizer plant and the South Pasture beneficiation plant, and facing adverse market conditions, Mosaic idled the South Pasture beneficiation plant in September 2018. Idling of the South Pasture Mine beneficiation plant in September 2018 resulted in no tailings sand being produced by the processing of phosphate matrix. As a

46

result, there was no tailings sand available for use in sand backfilling reclamation at the South Pasture Mine, and specifically, the two Reclamation Units identified in the County’s January 8th NOV.

On March 10, 2020, Mosaic filed an “Application for Waiver and Reclamation Schedule Extension” to secure Board of County Commissioners (“BOCC”) approval of extended reclamation deadlines for the South Pasture Mine. To obtain waiver relief from the BOCC, a quasi-judicial hearing would be required.

Extensive negotiations between Mosaic and County legal and technical staff resulted in an agreement that involved two separate but related actions: (1) secure a Waiver and Reclamation Schedule Extension through formal action by the BOCC at a quasi-judicial public hearing; and (2) enter into a Settlement Agreement that would require payment of a civil penalty by Mosaic for the non-compliance in meeting the required reclamation deadlines of the South Pasture Mine Development Order and the County Mining Ordinance. The Settlement Agreement would also be presented and acted upon at a formal public hearing before the BOCC.

On May 7, 2020, a quasi-public judicial hearing was held before the Hardee County BOCC. At that hearing, the BOCC voted unanimously to issue a Waiver of the applicable reclamation deadlines of the South Pasture Development Order and the County Ordinance for three specific reclamation areas of the South Pasture Mine. The Waiver also included a negotiated Alternative Reclamation Schedule that extends the deadline for completion of reclamation until the end of 2023. At that same hearing, the BOCC approved a Settlement Agreement that resolved all outstanding non-compliance associated with reclamation obligations at the South Pasture Mine and requires Mosaic to pay an agreed settlement amount of $249,000.

Mosaic has satisfied the payment obligation of the Settlement Agreement and continues to implement the Alternative Reclamation Schedule, as required. Monitoring programs have been put in place to ensure continued compliance with the Waiver and Settlement Agreement.

Cruz Litigation. On August 27, 2020, a putative class action complaint was filed in Circuit Court of the Thirteenth Judicial Circuit in Hillsborough County, FL against our wholly owned subsidiary, Mosaic Global Operations Inc. and two co-defendants. The complaint alleges claims related to elevated levels of radiation at two manufactured housing communities located on reclaimed mining land in Mulberry, Polk County, Florida, allegedly due to phosphate mining and reclamation activities occurring decades ago. Plaintiffs seek monetary damages, including punitive damages, injunctive relief requiring remediation of their properties, and a medical monitoring program funded by the defendants. We intend to vigorously defend this matter.

47

ITEM 1A. RISK FACTORS

Important risk factors that apply to us are outlined in Item 1A in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “10-K Report”). In addition to these risk factors, we include the following update:

Operational Risks

We use tailings, sediments and water dams, clay settling areas and phosphogypsum stacks to manage residual materials generated in our mining and fertilizer production operations. If our safety procedures are not effective, an accident involving these impoundments could result in serious injuries or death, damage to property or the environment, or result in the shutdown of our facilities, any of which could materially adversely affect our results of operations.

Mining and processing of potash and phosphate generate residual materials that must be managed both during the operation of the facility and upon facility closure. Potash tailings, consisting primarily of salt and clay, are stored in surface disposal sites. Phosphate clay residuals from mining are deposited in large tailing dams in Brazil and in clay settling areas and phosphogypsum stacks in the United States. They are regularly monitored to evaluate structural stability and for leaks. The failure of or a breach at any of our tailings dams and other impoundments at any of our operations could cause severe property and environmental damage and loss of life, could result in the shut down or idling of our facilities and could have a material adverse effect on our results of operations.

Legislation at both Brazilian federal and state levels has introduced new rules regarding tailings dam safety, construction, licensing and operations. We cannot predict the full impact of these legislative or potentially related judicial actions, or future actions, or whether or how it would affect our Brazilian operations or customers.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Pursuant to our employee stock plans relating to the grant of employee stock options, stock appreciation rights, restricted stock unit awards, and other equity-based awards, we have granted and may in the future grant employee stock options to purchase shares of our Common Stock for which the purchase price may be paid by means of delivery to us by the optionee of shares of our Common Stock that are already owned by the optionee (at a value equal to market value on the date of the option exercise). During the periods covered by this report, no options to purchase shares of our Common Stock were exercised for which the purchase price was so paid.

On May 14, 2015, we announced our 2015 Repurchase Program, which allows us to repurchase up to $1.5 billion of our Common Stock through open market purchases, accelerated share repurchase arrangements, privately negotiated transactions or otherwise. No repurchases were made in the three months ended March 31, 2021.

ITEM 4. MINE SAFETY DISCLOSURES

Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this report.

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 Phosphates 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. As part of the Acquisition, we acquired an additional 40% economic interest in the Miski Mayo Phosphate Mine in Peru, which increased our aggregate interest to 75%. These results are consolidated in the Phosphates segment. The Phosphates segment also includes our 25% interest in the Ma’aden Wa’ad Al Shamal Phosphate Company (the “MWSPC”), a joint venture to develop, own and operate integrated phosphate production facilities in the Kingdom of Saudi Arabia. We market approximately 25% of the 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 (Loss).

•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 acquisition (the “Acquisition”) of Vale Fertilizantes S.A. (now known as Mosaic Fertilizantes P&K S.A. or the “Acquired Business”), 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 crop nutrition port and throughput warehouse terminal facility in Brazil.

Intersegment eliminations, unrealized mark-to-market gains/losses on derivatives, debt expenses, Streamsong Resort® results of operations, and the results of the China and India distribution businesses are included within Corporate, Eliminations and Other.

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, 2020 (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.

Recently Issued Accounting Guidance [Abstract]
Accounting Standards Update and Change in Accounting Principle [Text Block]	Recently Issued Accounting GuidanceIn June 2016, the Financial Accounting Standards Board (“FASB”) issued guidance which revises the accounting for credit losses on financial instruments within its scope. The standard introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade and other receivables, and modifies the impairment model for available-for-sale (“AFS”) debt securities. The guidance amends the current other-than-temporary impairment model for AFS debt securities and provides that any impairment related to credit losses be recognized as an allowance (which could be reversed) rather than as a permanent reduction in the amortized cost basis of that security. We adopted this standard prospectively on January 1, 2020 and revised our accounting policies and procedures to reflect the requirements of this standard related to our trade receivables and AFS debt securities. Based on the composition of our trade receivables, current market conditions, and historical and expected credit loss activity, adoption of this standard did not significantly impact our consolidated results of operations or financial condition.

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 March 31,

Goodwill Mosaic had goodwill of $1.2 billion as of March 31, 2021 and December 31, 2020, respectively. We review goodwill for impairment annually in October and at any time events or circumstances indicate that the carrying value may not be fully

recoverable, which is based on our accounting policy and GAAP. The changes in the carrying amount of goodwill, by reporting unit, are as follows:

	Potash		Mosaic Fertilizantes		Corporate, Eliminations and Other		Total

We are required to perform our next annual goodwill impairment analysis as of October 31, 2021. It is possible that, during the remainder of 2021 or beyond, business conditions could deteriorate from the current state, raw material or product price projections could decline significantly from current estimates, or our common stock price could decline significantly. If projected net sales and cash flow projections are not achieved or our common stock price significantly declines from current levels, book values of certain operations could exceed their fair values, which may result in goodwill impairment charges in future periods. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

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 9 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 carrying value of an investment is impaired on an other-than-temporary basis.

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.

There were no other-than-temporary impairment write-downs on available-for-sale securities during the three months ended March 31, 2021.

The estimated fair value of the investments in the RCRA Trusts as of March 31, 2021 and December 31, 2020 are as follows:

Financing Arrangements [Abstract]

Financing Arrangements

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 financing 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 and Mosaic makes payment to the third-party intermediary at a later date, stipulated in accordance with the commercial terms negotiated. As of March 31, 2021 and December 31, 2020, the total structured accounts payable arrangements were $797.5 million and $640.0 million, respectively.

Receivable Purchasing Arrangement

On March 4, 2020, we entered into a Receivable Purchasing Agreement (“RPA”), with a bank whereby, from time-to-time, we sell certain receivables. The net face value of the purchased receivables may not exceed $150 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. As of December 31, 2020, there was no outstanding balance under this facility. In January 2021, we entered into a First Amendment to the RPA. This amendment made certain adjustments so that the receivables sold under the RPA will be 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. Prior to the amendment, we recorded the purchase price as short-term debt, and recognized interest expense by accreting the liability through the due date of the underlying receivables.

During the three months ended March 31, 2021 and 2020, the Company sold approximately $86.6 million and $101.5 million, respectively, of accounts receivable under this arrangement. Discounts on sold receivables were not material for any period presented. Following the sale to the bank, we continue to service the collection of the receivable on behalf of the bank without further consideration. As of March 31, 2021, $86.6 million had been collected but not yet remitted to the bank. This amount is classified in accrued liabilities on the Condensed Consolidated Balance Sheets. Cash collected and remitted are presented as financing activities in the Condensed Consolidated Statements of Cash Flows.

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 acquired as part of the Acquisition and (viii) decommission plant sites and close Gypstacks in Brazil, also as part of the Acquisition. 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)	March 31, 2021		December 31, 2020
AROs, beginning of period	$	1,393.9	$	1,315.2

Non-current portion of AROs	$	1,182.2	$	1,203.7

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, Mulberry, 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 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 7 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, 2020, 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 $1.6 billion, and the present value of our Gypstack Closure Costs ARO reflected in our Consolidated Balance Sheet for those facilities was approximately $439.1 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 $243.2 million, which reflects our closure cost estimates as of December 31, 2020. 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 March 31, 2021 and December 31, 2020, 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 $247.9 million and $251.8 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 Phosphates 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 three months ended March 31, 2021, gross unrecognized tax benefits increased by $0.6 million to $37.5 million. The increase is primarily related to recording non-U.S. reserves and foreign exchange. If recognized, approximately $20.3 million of the $37.5 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 $9.4 million and $9.0 million as of March 31, 2021 and December 31, 2020, 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 tax 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 is currently in negotiations with non-U.S. tax authorities where settlements could result in different tax outcomes than what is currently accounted for. The Company believes that any issues raised have been properly accounted for.

For the three months ended March 31, 2021, tax expense specific to the period was a cost of approximately $4.4 million. This consisted primarily of tax cost of $2.3 million recorded related to non-U.S. prior year adjustments, $2.0 million related to the write-off of expired stock options, and other miscellaneous costs of $0.1 million. 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, by a benefit associated with non-U.S. incentives, by changes in valuation allowances 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.

Generally, for interim periods, income tax is equal to the total of (1) year-to-date pretax income multiplied by our forecasted effective tax rate plus (2) tax expense items specific to the period. In situations where we expect to report losses for which we do not expect to receive tax benefits, we are required to apply separate forecasted effective tax rates to those jurisdictions rather than including them in the consolidated effective tax rate. For the three months ended March 31, 2021, income tax expense was not impacted by this set of rules.

For the three months ended March 31, 2020, tax expense specific to the period was a benefit of approximately $28.3 million. This consisted primarily of tax benefit of $25.1 million recorded related to the impacts of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to prior years. The CARES Act provides various tax relief measures to taxpayers impacted by the coronavirus. Tax expense specific to the period also included a benefit of $5.5 million related to release of the sequestration on AMT, which was partially offset by a share-based excess cost of $1.7 million and changes in estimates related to prior years of $0.6 million. 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, and by the impact of certain entities being taxed in both foreign jurisdictions 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 ActivitiesWe 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 March 31, 2021 and December 31, 2020.

As of March 31, 2021 and December 31, 2020, the gross asset position of our derivative instruments was $61.5 million and $65.3 million, respectively, and the gross liability position of our liability instruments was $37.8 million and $49.9 million, respectively.

As of March 31, 2021 and December 31, 2020, the following is the total absolute notional volume associated with our outstanding derivative instruments:

(in millions of Units)			March 31, 2021	December 31, 2020
Derivative Instrument	Derivative Category	Unit of Measure
Foreign currency derivatives	Foreign currency	US Dollars	2,399.2	2,912.3
Natural gas derivatives	Commodity	MMbtu	34.1	27.3

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 March 31, 2021 and December 31, 2020, was $12.8 million and $11.3 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 March 31, 2021, we would have been required to post an additional $8.3 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 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 and zero-cost collars, which typically expire within eighteen 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 March 31, 2021 and December 31, 2020, the gross asset position of our foreign currency derivative instruments was $53.3 million and $58.6 million, respectively, and the gross liability position of our foreign currency derivative instruments was $36.9 million and $48.7 million, respectively.

Commodity Derivatives - The commodity contracts primarily relate to natural gas. The commodity derivative instruments that we currently use are forward purchase contracts, swaps, and three-way collars. 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 March 31, 2021 and December 31, 2020, the gross asset position of our commodity derivative instruments was $8.2 million and $6.7 million, respectively, and the gross liability position of our commodity instruments was $0.9 million and $1.2 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. In April 2020, we terminated our outstanding interest rate swap contracts which resulted in an immaterial impact to our Condensed Consolidated Statement of Earnings (Loss).

Financial Instruments

The carrying amounts and estimated fair values of our financial instruments are as follows:

	March 31, 2021				December 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Cash and cash equivalents	$	692.0	$	692.0	$	574.0	$	574.0
Accounts receivable	851.6		851.6		881.1		881.1
Accounts payable	762.3		762.3		769.1		769.1
Structured accounts payable arrangements	797.5		797.5		640.0		640.0
Short-term debt	15.1		15.1		0.1		0.1
Long-term debt, including current portion	4,469.5		4,950.8		4,578.0		5,172.1

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.

Related Party Transactions

We enter into transactions and agreements with certain of our non-consolidated companies and other related parties from time to time. As of March 31, 2021 and December 31, 2020, the net amount due from our affiliates and non-consolidated companies totaled $1.4 million and $55.9 million, respectively. These amounts include a long-term indemnification asset from Vale S.A. for reimbursement of pension plan obligations. This asset had a balance of $21.0 million and $23.0 million as of March 31, 2021 and December 31, 2020, respectively.

The Condensed Consolidated Statements of Earnings included the following transactions with our non-consolidated companies:

	Three Months Ended March 31,
	2021		2020
Transactions with related parties included in net sales	$	157.4	$	148.6
Transactions with related parties included in cost of goods sold	217.7		177.1

As part of the MWSPC joint venture, we market approximately 25% of the MWSPC production. Marketing fees of approximately $1.6 million and $2.4 million are included in revenue for the three months ended March 31, 2021 and March 31, 2020, respectively.

In 2015, we agreed to provide funds to finance the purchase and construction of two articulated tug and barge units, intended to transport anhydrous ammonia for our operations, through a bridge loan agreement with Gulf Marine Solutions, LLC (“GMS”). GMS is a wholly owned subsidiary of Gulf Sulphur Services Ltd., LLLP (“Gulf Sulphur Services”), an entity in which we and a joint venture partner, Savage Companies (“Savage”), each indirectly own a 50% equity interest and for which a subsidiary of Savage provides operating and management services. GMS provided these funds through draws on the Mosaic bridge loan and through additional loans from Gulf Sulphur Services. We are the primary beneficiary of GMS, a variable interest entity, and consolidate GMS’s operations in our Phosphates segment.

On October 24, 2017, a lease financing transaction was completed with respect to the completed tug and barge unit, and, following the application of proceeds from the transaction, all outstanding loans made by Gulf Sulphur Services to GMS, together with accrued interest, were repaid, and the bridge loans related to the first unit’s construction were repaid. As of March 31, 2021 and December 31, 2020, there were outstanding bridge loans of $74.7 million relating to the cancelled second barge and the remaining tug, which bridge loans are eliminated in consolidation. Reserves against the bridge loans of approximately $54.2 million were established in 2018 and remain unchanged. Several subsidiaries of Savage operate vessels utilized by Mosaic under time charter arrangements, including the ammonia tug and barge unit.

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 $56.4 million and $61.4 million as of March 31, 2021 and December 31, 2020, 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 Water Loss Incident. In August 2016, a sinkhole developed under one of the two cells of the active Gypstack at our New Wales facility in Polk County, Florida, resulting in process water from the stack draining into the sinkhole. The incident was reported to the FDEP and EPA. In October 2016, our subsidiary, Mosaic Fertilizer, entered into a consent order (the “Order”) with the FDEP relating to the incident. Under the Order, Mosaic Fertilizer agreed to, among other things: implement a remediation plan to close the sinkhole; perform additional monitoring of the groundwater quality and act to assess and remediate in the event monitored off-site water does not comply with applicable standards as a result of the incident; evaluate the risk of potential future sinkhole formation at the New Wales facility and at Mosaic Fertilizer’s active Gypstack operations at the Bartow, Riverview and Plant City facilities and provide recommendations to address any identified issues; and provide financial assurance of no less than $40.0 million, which we have done without the need for any expenditure of corporate funds through satisfaction of a financial strength test and Mosaic parent guarantee. The Order did not require payment of civil penalties relating to the incident.

As of March 31, 2021, the sinkhole repairs were substantially complete. Additional expenditures could be required in the future for additional remediation or other measures in connection with the sinkhole including if, for example, FDEP or EPA were to request additional measures to address risks presented by the Gypstack. These expenditures could be material. In addition, we

are unable to predict at this time what, if any, impact the New Wales water loss incident will have on future Florida permitting efforts.

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 9 of our Notes to Condensed Consolidated Financial Statements.

Florida Sulfuric Acid Plants. On April 8, 2010, EPA Region 4 submitted an administrative subpoena to us under Section 114 of the Federal Clean Air Act (the “CAA”) regarding compliance of our Florida sulfuric acid plants with the “New Source Review” requirements of the CAA. The request received by Mosaic appears to be part of a broader EPA national enforcement initiative focusing on sulfuric acid plants. On June 6, 2010, EPA issued a notice of violation to CF (the “CF NOV”) with respect to “New Source Review” compliance at the Plant City Facility's sulfuric acid plants and the allegations in the CF NOV were not resolved before our 2014 acquisition of the Plant City Facility. CF has agreed to indemnify us with respect to any penalty EPA may assess as a result of the allegations in the CF NOV.

We have been engaged in settlement discussions with U.S. EPA and the Department of Justice, originating with the allegations of violations of Clean Air Act Prevention of Significant Deterioration (“PSD”) permitting requirements at the Plant City sulfuric acid plants and encompassing injunctive relief regarding sulfur dioxide emissions across Mosaic’s Florida sulfuric acid plant fleet. With the closure of Plant City fertilizer operations, there is no longer a need to reach resolution with the government on injunctive relief (i.e., reduction of sulfur dioxide emissions) at that facility. Furthermore, the Department of Justice has determined that there is no basis for proceeding with a settlement, as EPA and the Department have not currently alleged any violations of the Clean Air Act PSD permitting requirements at any other of Mosaic’s Florida sulfuric acid plants.

We cannot predict at this time whether EPA and DOJ will initiate an enforcement action in the future with respect to “New Source Review” compliance at our Florida sulfuric acid plants or what its scope would be, or what the range of outcomes might be with respect to such a potential enforcement action.

Uncle Sam Gypstack. In January 2019, we observed lateral movement of the north slope of our active phosphogypsum stack at the Uncle Sam facility in Louisiana. The observation was reported to the Louisiana Department of Environmental Quality and the U.S. EPA. We continue to provide updates to the agencies on the movement, which has slowed following actions we have taken, which include reducing process water volume stored atop the stack to reduce the active load causing the movement; constructing a stability berm at the base of the slope to increase resistance; and removing gypsum from the north side to the south side. These steps have improved slope stability, reduced slope movement and reduced our capacity to store process water. There has been no loss of containment resulting from the movement observed, and none is expected. Although continued lateral movement on the north slope could have a material effect on our future operations at that facility, we cannot predict the prospective impact on our results of operations at this time.

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.

In September 2019, counsel for several of the parishes announced that an agreement had been reached to settle the claims against Mosaic and its corporate predecessors, subject to approval by the participating parishes and the State of Louisiana. In connection with that settlement agreement, the proposed settlement payment obligations would be paid by third-party indemnitors.

Phosphate Mine Permitting in Florida

Denial of the permits sought at any of our mines, issuance of the permits with cost-prohibitive conditions, substantial delays in issuing the permits, legal actions that prevent us from relying on permits or revocation of permits may create challenges for us to mine the phosphate rock required to operate our Florida and Louisiana phosphate plants at desired levels or increase our costs in the future.

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 $748 million. We estimate that our probable aggregate loss with respect to these claims is approximately $57.5 million, which is included in our accrued liabilities in our Condensed Consolidated Balance Sheet as of March 31, 2021.

Approximately $596.5 million of the maximum potential loss relates to labor claims, such as in-house and third-party employees’ judicial proceedings alleging the right to receive overtime pay, additional payment due to work in hazardous conditions, risk premium, profit sharing, additional payment due to night work, salary parity and wage differences. We estimate that our probable aggregate loss regarding these claims is approximately $51.4 million, which has been accrued as of March 31, 2021.

Based on Brazilian 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.

The environmental judicial and administrative proceedings claims allege aggregate damages and/or fines in excess of $17.1 million; however, we estimate that our probable aggregate loss regarding these claims is approximately $4.4 million, which has been accrued as of March 31, 2021.

The mining judicial and administrative proceedings claims allege aggregate damages and/or fines of approximately $3.6 million. We estimate that our probable aggregate loss regarding these claims will be immaterial as of March 31, 2021.

Our Brazilian subsidiaries also have certain other civil contingent liabilities with respect to judicial, administrative and arbitration proceedings and claims related to contract disputes, pension plan matters, real state disputes, regulatory issues and other civil matters arising in the ordinary course of business. These claims allege aggregate damages in excess of $130.9 million. We estimate that the probable aggregate loss with respect to these matters is approximately $1.7 million.

Uberaba Judicial Settlement

In 2013, the Federal Public Prosecutor filed a public civil action requesting that the Company adopt several measures to mitigate soil and water contamination related to the Gypstack at our Uberaba facility, located in the State of Minas Gerais, including compensation for the alleged social and environmental damages. In 2014, our predecessor subsidiary in Brazil entered into a judicial settlement with the Federal Public Prosecutor, the State of Minas Gerais public prosecutor and the federal environmental agency. Under this agreement, we agreed to implement remediation measures such as: constructing a liner under the Gypstack water ponds and lagoons, and monitoring the groundwater and soil quality. We also agreed to create a private reserve of natural heritage and to pay compensation in the amount of approximately $0.3 million, which was paid in July 2018. We are currently acting in compliance with our obligations under the judicial settlement and expect them to be completed by December 31, 2023.

Uberaba EHS Class Action

In 2013, the State of Minas Gerais public prosecutor filed a class action claiming that our predecessor company in Brazil did not comply with labor safety rules and working hour laws. This claim was based on an inspection conducted by the Labor and Employment Ministry in 2010, following which we were fined for not complying with several labor regulations. We filed our defense, claiming that we complied with these labor regulations and that the assessment carried out by the inspectors in 2010 was abusive. Following the initial hearing, the court ordered an examination to determine whether there has been any non-compliance with labor regulations. The examination is currently pending and the parties are negotiating a settlement. The amount claimed in the proceeding is $27.5 million.

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 $331.2 million, of which $154.3 million is subject to an indemnification agreement entered into with Vale S.A in connection with the Acquisition.

Approximately $217.4 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. Based on Brazil 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.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2021

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, 2020 (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

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
