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 as well as businesses in which we own less than a majority or a noncontrolling 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. Additionally, the Phosphates segment has a 35% economic interest in a joint venture that owns a phosphate rock mine (the “Miski Mayo Mine”) in Peru. On August 5, 2013 Mosaic entered into an agreement to form a joint venture (the “Northern Promise Joint Venture”), of which Mosaic will own 25%, with Saudi Arabian Mining Company (“Ma’aden”) and Saudi Basic Industries Corporation (“SABIC”) to develop a phosphate rock mine and chemical complexes that is presently contemplated to produce phosphate fertilizers, animal feed, food grade purified phosphoric acid and sodium tripolyphosphate in the Kingdom of Saudi Arabia.

Our Phosphates segment’s results also include our North American phosphate distribution activities and all of our international distribution activities as well as the results of Phosphate Chemicals Export Association, Inc. (“PhosChem”), a U.S. Webb-Pomerene Act association of phosphate producers that exports concentrated phosphate crop nutrient products around the world for us and PhosChem’s other member. Our share of PhosChem’s sales of dry phosphate crop nutrient products was approximately 93% for the three months ended September 30, 2013. Effective December 31, 2013, PhosChem will be dissolved.

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.

Intersegment sales are eliminated within Corporate, Eliminations and Other. See Note 14 to our Condensed Consolidated Financial Statements in this report for segment results.

As previously announced, we are changing our fiscal year end to December, 31 from May 31 and began reporting our quarterly results on a calendar-year basis for the months of July through September 2013. Our first full calendar reporting year will be 2014. In connection with this change, we have included the Condensed Consolidated Statement of Earnings and selected cash flow information for the four months ended September 30, 2013 in Note 18.

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

6

Table of Contents

THE MOSAIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

financial information that are normally required by accounting principles generally accepted in the United States (“U.S. 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 except as noted in these Notes to the Condensed Consolidated Financial Statements) necessary for a fair statement 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 fiscal year ended May 31, 2013. 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 and its majority owned subsidiaries, as well as the accounts of certain variable interest entities (“VIEs”) for which we are 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 U.S. 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 more significant estimates made by management relate to the recoverability of non-current assets, the useful lives of long-lived assets, environmental and reclamation liabilities, the costs of our employee benefit obligations for pension plans and postretirement benefits, income tax-related accounts, including the valuation allowance against deferred income tax assets, Canadian resource taxes and royalties, inventory valuation and accruals for pending legal matters. Actual results could differ from these estimates.

3. Recently Issued Accounting Guidance

Recently Adopted Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities” which enhances current disclosures about financial instruments and derivative instruments that are either offset on the statement of financial position or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset on the statement of financial position. Entities are required to provide both net and gross information for these assets and liabilities in order to facilitate comparability between financial statements prepared on the basis of U.S. GAAP and those prepared on the basis of International Financial Reporting Standards (“IFRS”). In January 2013, the FASB issued ASU No. 2013-01, “Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” to limit the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are offset in the financial statements or subject to an enforceable master netting arrangement or similar agreement. These standards were effective for us beginning June 1, 2013 with retrospective application required. We determined that these requirements were not material to the results of operations or financial position, and, therefore, have not added disclosures otherwise required by these standards.

In February 2013, the FASB issued ASU No. 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” which requires entities to disclose additional information about changes in and significant items reclassified out of accumulated other

7

Table of Contents

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

comprehensive income. This guidance was effective for us beginning June 1, 2013. We determined that these requirements were not material to the results of operations or financial position and, therefore, have not added disclosures otherwise required by this standard.

Pronouncements Issued But Not Yet Adopted

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” which requires that an unrecognized tax benefit should be presented in the financial statements as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the law. This guidance is effective for us beginning January 1, 2014 and will be applied on a prospective basis to all unrecognized tax benefits that exist at the effective date. We do not expect this guidance to have a material impact on our results of operations or financial position.

4. Other Financial Statement Data

The following provides additional information concerning selected balance sheet accounts:

Table of Contents

THE MOSAIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

5. 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. The following is a reconciliation of the denominator for the basic and diluted EPS computations:

A total of 1.4 million and 0.9 million shares of common stock subject to issuance upon exercise of stock options for the three months ended September 30, 2013 and 2012, respectively, have been excluded from the calculation of diluted EPS as the effect would have been anti-dilutive.

6. Income Taxes

We record unrecognized tax benefits in accordance with applicable accounting standards. During the three months ended September 30, 2013, gross unrecognized tax benefits decreased by $46.3 million to $270.5 million. We recorded a gross decrease of $69.7 million due to the resolution of certain tax matters in various jurisdictions, of which $17.0 million impacted our effective tax rate. The decrease was partially offset by a net increase in unrecognized tax benefits associated with the current and prior fiscal years. If recognized, approximately $97.7 million of the $270.5 million in unrecognized tax benefits would affect our effective tax rate 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 $50.3 million and $53.8 million as of September 30, 2013 and May 31, 2013, respectively, that were included in other noncurrent liabilities in the Condensed Consolidated Balance Sheets.

Based upon the information available as of September 30, 2013, we anticipate that the amount of uncertain tax positions will change in the next twelve months; however, the change cannot reasonably be estimated.

7. Inventories

Inventories consist of the following:

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

8. Goodwill

The changes in the carrying amount of goodwill, by reporting unit, are as follows:

We review goodwill for impairment annually or at any time events or circumstances indicate that the carrying value may not be fully recoverable. Under our accounting policy, an annual review is performed in November of each year, or more frequently if indicators of potential impairment exist.

9. Variable Interest Entities

Mosaic is the primary beneficiary of and consolidates two VIEs within our Phosphates segment: PhosChem and South Fort Meade Partnership, L.P. (“SFMP”). We determine whether we are the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the purpose and design of the VIE, the risks that the VIE were designed to create and pass along to other entities, the activities of the VIE that could be directed and which entity could direct them, and the expected relative impact of those activities on the economic performance of the VIE. We assess our VIE determination with respect to an entity on an ongoing basis. We have not identified any additional VIEs in which we hold a significant interest.

PhosChem is an export association of United States phosphate producers that markets our phosphate products internationally. We, along with the other member, are, subject to certain conditions and exceptions, contractually obligated to reimburse PhosChem for our respective pro rata share of any operating expenses or other liabilities. PhosChem had net sales of $228.0 million and $323.3 million for the three months ended September 30, 2013 and 2012, respectively, which are included in our consolidated net sales. PhosChem currently funds its operations through ongoing sales.

We determined that, because we are PhosChem’s exclusive export agent for the marketing, solicitation of orders and freighting of dry phosphatic materials, we have the power to direct the activities that most significantly impact PhosChem’s economic performance. Because Mosaic accounts for the majority of sales volume marketed through PhosChem, we have the obligation to absorb losses or right to receive benefits that could be significant to PhosChem.

SFMP owns the mineable acres at our South Fort Meade phosphate mine. We have a long-term mineral lease with SFMP which, in general, expires on the earlier of: (i) December 31, 2025, or (ii) the date that we have completed mining and reclamation obligations associated with the leased property. In addition to lease payments, we pay SFMP a royalty on each tonne mined and shipped from the areas that we lease. SFMP had no external sales for the three months ended September 30, 2013 and 2012.

We determined that, because we control the day-to-day mining decisions and are responsible for obtaining mining permits, we have the power to direct the activities that most significantly impact SFMP’s economic performance. Because of our rental and royalty payments to the partnership, we have the obligation to absorb losses or right to receive benefits that could potentially be significant to SFMP.

No additional financial or other support has been provided to these VIE’s beyond what was previously contractually required during any periods presented. The carrying amounts and classification of assets and liabilities included in our Condensed Consolidated Balance Sheets for these consolidated entities are as follows:

10. Contingencies

We have described below judicial and administrative proceedings to which we are subject.

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 $23.7 million and $24.7 million as of September 30, 2013 and May 31, 2013, 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.

EPA RCRA Initiative. In 2003, the U.S. Environmental Protection Agency (“EPA”) Office of Enforcement and Compliance Assurance announced 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. Mining and processing of phosphates generate residual materials that must be managed both during the operation of a facility and upon a facility’s closure. Certain solid wastes generated by our phosphate operations may be subject to regulation under RCRA and related state laws. The EPA rules exempt “extraction” and “beneficiation” wastes, as well as 20 specified “mineral processing” wastes, from the hazardous waste management requirements of RCRA. Accordingly, certain of the residual materials which our phosphate operations generate, as well as process wastewater from phosphoric acid production, are exempt from RCRA regulation. However, the generation and management of other solid wastes from phosphate operations may be subject to hazardous waste regulation if the waste is deemed to exhibit a “hazardous waste characteristic.” As part of its initiative, we understand that EPA has inspected all or nearly all facilities in the

11

Table of Contents

THE MOSAIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

U.S. phosphoric acid production sector to ensure compliance with applicable RCRA regulations and to address any “imminent and substantial endangerment” found by the EPA under RCRA. We have provided the EPA with substantial amounts of information regarding the process water recycling practices and the hazardous waste handling practices at our phosphate production facilities in Florida and Louisiana, and the EPA has inspected all of our currently operating processing facilities in the U.S. In addition to the EPA’s inspections, our phosphates concentrates facilities have entered into consent orders to perform analyses of existing environmental data, to perform further environmental sampling as may be necessary, and to assess whether the facilities pose a risk of harm to human health or the surrounding environment.

We have received Notices of Violation (“NOVs”) from the EPA related to the handling of hazardous waste at our Riverview (September 2005), New Wales (October 2005), Mulberry (June 2006), Green Bay (August 2006) and Bartow (September 2006) facilities in Florida. The EPA has issued similar NOVs to our competitors and referred the NOVs to the U.S. Department of Justice (“DOJ”) for further enforcement. We currently are engaged in discussions with the DOJ and EPA. We believe we have substantial defenses to allegations in the NOVs, including but not limited to previous EPA regulatory interpretations and inspection reports finding that the process water handling practices in question comply with the requirements of the exemption for extraction and beneficiation wastes. We intend to evaluate various alternatives and continue discussions to determine if a negotiated resolution can be reached. If it cannot, we intend to vigorously defend these matters in any enforcement actions that may be pursued.

We are negotiating the terms of a possible settlement with the EPA, the DOJ, the Florida Department of Environmental Protection and the Louisiana Department of Environmental Quality (collectively, the “Government”) and the final terms are not yet agreed upon or approved. If a settlement can be achieved, in all likelihood our commitments would be multi-faceted with key elements including, in general and among other elements, the following:

12

Table of Contents

THE MOSAIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In light of our strong operating cash flows, liquidity and capital resources, we believe that we have sufficient liquidity and capital resources to be able to fund such capital expenditures, financial assurance requirements and civil penalties as part of a settlement. If a settlement cannot be agreed upon, we cannot predict the outcome of any litigation or estimate the potential amount or range of loss; however, we would face potential exposure to material costs should we fail in the defense of an enforcement action.

EPA EPCRA Initiative. In July 2008, the DOJ sent a letter to major U.S. phosphoric acid manufacturers, including us, stating that the EPA’s ongoing investigation indicates apparent violations of Section 313 of the Emergency Planning and Community Right-to-Know Act (“EPCRA”) at their phosphoric acid manufacturing facilities. Section 313 of EPCRA requires annual reports to be submitted with respect to the use or presence of certain toxic chemicals. DOJ and EPA also stated that they believe that a number of these facilities have violated Section 304 of EPCRA and Section 103 of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) by failing to provide required notifications relating to the release of hydrogen fluoride from the facilities. The letter did not identify any specific violations by us or assert a demand for penalties against us. We cannot predict at this time whether the EPA and DOJ will initiate an enforcement action over this matter, what its scope would be, or what the range of outcomes of such a potential enforcement action might be.

Florida Sulfuric Acid Plants. On April 8, 2010, the 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. We cannot predict at this time whether the EPA and DOJ will initiate an enforcement action over this matter, what its scope would be, or what the range of outcomes of such a potential enforcement action might be.

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 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. Potential indemnification is not considered in our established accruals.

Phosphate Mine Permitting in Florida

Denial of the permits sought at any of our mines, issuance of the permits with cost-prohibitive conditions, or 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.

The Altman Extension of the Four Corners Mine. The Army Corps of Engineers (the “Corps”) issued a federal wetlands permit under the Clean Water Act (the “CWA”) for mining the Altman Extension (the “Altman Extension”) of our Four Corners phosphate rock mine in central Florida in May 2008. The Sierra Club, Inc. (the “Sierra Club”), Manasota-88, Inc. (“Manasota-88”), Gulf Restoration Network, Inc., People for Protecting Peace River, Inc. (“People for Protecting Peace River”) and the Environmental Confederation of Southwest Florida, Inc. sued the Corps in the United States District Court for the Middle District of Florida, Jacksonville Division (the “Jacksonville District Court”), seeking to vacate our permit to mine the Altman Extension. On September 30, 2013, the Jacksonville District Court granted our motion for summary judgment and denied the plaintiffs’ motion for summary judgment, resulting in dismissal of the plaintiffs’ lawsuit. The time for the plaintiffs to appeal or request a rehearing has not yet expired.

MicroEssentials^® Patent Lawsuit

On January 9, 2009, John Sanders and Specialty Fertilizer Products, LLC filed a complaint against Mosaic, Mosaic Fertilizer, LLC, Cargill, Incorporated and Cargill Fertilizer, Inc. in the United States District Court for the Western District of Missouri (the “Missouri District Court”). The complaint alleges that our production of MicroEssentials^® SZ, one of several types of the MicroEssentials^® value-added ammoniated phosphate crop nutrient products that we produce, infringes on a patent held by the plaintiffs since 2001. Plaintiffs have since asserted that other MicroEssentials^® products also infringe the patent. Plaintiffs seek to enjoin the alleged infringement and to recover an unspecified amount of damages and attorneys’ fees for past infringement. Our answer to the complaint responds that the plaintiffs’ patent is invalid and we have counterclaimed that the plaintiffs have engaged in inequitable conduct.

The Missouri District Court stayed the lawsuit pending an ex parte reexamination of plaintiffs’ patent claims by the U.S. Patent and Trademark Office (the “PTO”). On September 12, 2012, Shell Oil Company (“Shell”) filed an inter parties reexamination request which in part asserted that the claims as amended and added in connection with the ex parte reexamination are unpatentable. On October 4, 2012, the PTO issued an Ex Parte Reexamination Certificate in which certain claims of the plaintiffs’ patent were cancelled, disclaimed and amended, and new claims were added. Plaintiffs have filed a motion with the Missouri District Court requesting that the stay of the lawsuit be lifted, and we have opposed that motion. On November 28, 2012, the PTO granted Shell’s request for an inter parties reexamination. On December 11, 2012, as part of that reexamination, the PTO issued an initial rejection of all of plaintiffs’ remaining patent claims. On September 12, 2013, the PTO reversed its initial rejection of the plaintiffs’ remaining patent claims and allowed them to stand. The time for Shell to appeal the PTO’s decision has not yet expired. A successful appeal by Shell could limit the claims the plaintiffs can assert against us or their remedies against us.

We believe that the plaintiffs’ allegations are without merit and intend to defend vigorously against them. At this stage of the proceedings, we cannot predict the outcome of this litigation, estimate the potential amount or range of loss or determine whether it will have a material effect on our results of operations, liquidity or capital resources.

Brazil Tax Contingencies

Our Brazilian subsidiary is 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 $96 million. Approximately $52 million of the maximum potential liability relates to PIS and Cofins tax credit cases while the majority of the remaining amount relates to various other non-income tax cases such as value added taxes. In the event that the Brazilian government was to prevail in connection with all judicial and administrative matters involving us and considering the amount of judicial deposits made, our maximum cash tax liability with respect to these matters would be approximately $94 million. Based on the current status of similar tax cases involving unrelated taxpayers, we believe we have recorded adequate accruals, which are immaterial, for the probable liability with respect to these Brazilian judicial and administrative proceedings.

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.

11. Accounting for Derivative Instruments and Hedging Activities

We are exposed to the impact of fluctuations in the relative value of currencies, the impact on interest rates, the impact of fluctuations in the purchase prices of natural gas, ammonia and sulfur consumed in operations and changes in freight costs. We periodically enter into derivatives in order to mitigate our foreign currency risks, interest rate risks and the effects of changing commodity and freight prices, but not for speculative purposes.

As of September 30, 2013 and May 31, 2013, the following is the total absolute notional volume associated with our outstanding derivative instruments:

We do not apply hedge accounting treatments to our foreign currency exchange contracts, commodities contracts, and 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 gain or loss 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) line in the Condensed Consolidated Statements of Earnings. Below is a table that shows the unrealized gains and (losses) on derivative instruments related to foreign currency exchange contracts, commodities contracts, and freight:

Table of Contents

THE MOSAIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The gross fair market value of all derivative instruments and their location in our Condensed Consolidated Balance Sheets are shown in the table below by asset or liability position and are further categorized by foreign currency, commodity, and freight derivatives:

We have entered into forward-starting interest rate swaps in anticipation of future debt issuance. These swap contracts are designated as cash flow hedges with unrealized gains and losses deferred to other comprehensive income and will be reclassified into earnings over the life of the associated debt once these contracts are settled. As of September 30, 2013, the total notional value of these swaps was $1.5 billion, with $1.25 billion related to ten-year term debt and $250.0 million related to thirty-year term debt. The fair market value of these contracts was ($1.9) million, with $7.3 million accounted as assets and $9.2 million accounted as liabilities as of September 30, 2013. These swap contracts will be settled in November 2013, or upon the earlier issuance of debt.

For additional disclosures about fair value measurement of derivative instruments, see Note 12 to the Condensed Consolidated Financial Statements in this report.

Credit-Risk-Related Contingent Features

Certain of our derivative instruments contain provisions that are governed by International Swap and Derivatives Association (“ISDA”) agreements with the counterparties. These agreements contain provisions that allow us to settle for the net amount between payments and receipts, and also state that if our debt were to be rated below investment grade, certain counterparties could request full collateralization on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position as of September 30, 2013, was $18.8 million. We have no cash collateral posted in association with these contracts. If the credit-risk-related contingent features underlying these agreements were triggered on September 30, 2013, we would be required to post $16.2 million of collateral assets, which are either cash or U.S. Treasury instruments, to the counterparties.

Counterparty Credit Risk

We enter into foreign exchange and 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

We determine the fair market values of our derivative contracts and certain other assets and liabilities based on the fair value hierarchy, described below, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels within the fair value hierarchy that may be used to measure fair value:

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.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents assets and liabilities included in our Condensed Consolidated Balance Sheets that are recognized at fair value on a recurring basis, and indicate the fair value hierarchy utilized to determine such fair values.

We did not significantly change our valuation techniques from prior periods.

Financial Instruments

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

For cash and cash equivalents, receivables, net, accounts payable trade 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 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.

13. Related Party Transactions

We enter into transactions and agreements with certain of our non-consolidated companies from time to time. As of September 30, 2013 and May 31, 2013, the net amount due from our non-consolidated companies totaled $23.6 million and $145.8 million, respectively.

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

14. 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. For a description of our business segments see Note 1 to the Condensed Consolidated Financial Statements in this report. 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. Corporate, Eliminations and Other primarily represents activities associated with our nitrogen distribution business, unallocated corporate office activities and eliminations. All intersegment transactions are eliminated within Corporate, Eliminations and Other. Segment information was as follows:
