[1]	See Note 7 for details of restructuring and other charges (income). Amounts for the years ended 2014, 2013 and 2012 relate to FMC Agricultural Solutions of $(4.5) million, $32.6 million and $8.5 million; FMC Health and Nutrition of $14.1 million, $1.0 million and $0.7 million; FMC Minerals of $0.1 million, $6.4 million and $13.0 million; and Corporate of $46.8 million, $7.9 million and $5.3 million, respectively.
[2]	Charges are associated with the previously planned separation of our FMC Corporation into two independent public companies. On September 8, 2014, we announced that we would no longer proceed with the planned separation of FMC into two distinct public entities. At that time we announced the acquisition of Cheminova; see Note 3 within these consolidated financial statements for more information. These charges are included within "Business separation costs" on our consolidated income statement. These costs were primarily related to professional fees associated with separation activities within the finance and legal functions through September 8, 2014.

Principal Accounting Policies and Related Financial Information [Abstract]
Principal Accounting Policies and Related Financial Information	Principal Accounting Policies and Related Financial Information
	Nature of operations. We are a diversified chemical company serving agricultural, consumer and industrial markets globally with innovative solutions, applications and market-leading products. We operate in three distinct business segments: FMC Agricultural Solutions, FMC Health and Nutrition and FMC Minerals. Our FMC Agricultural Solutions segment develops, markets and sells all three major classes of crop protection chemicals – insecticides, herbicides, and fungicides. These products are used in agriculture to enhance crop yield and quality by controlling a broad spectrum of insects, weeds and disease, as well as pest control in non-agricultural markets. FMC Health and Nutrition focuses on food, pharmaceutical ingredients, nutraceuticals, personal care and similar markets. Food ingredients are used to enhance texture, color, structure and physical stability; pharmaceutical additives are used for binding, encapsulation and disintegrant applications. Some of our products are increasingly being used as active ingredients in nutraceutical and pharmaceutical markets. Our FMC Minerals segment manufactures a wide range of inorganic materials, that are produced from two key minerals: Trona (soda ash) and lithium. See Note 22 for the subsequent event related to our FMC Minerals segment.
	Basis of consolidation and basis of presentation. The accompanying consolidated financial statements of FMC Corporation and its subsidiaries were prepared in accordance with accounting principles generally accepted in the United States of America. Our consolidated financial statements include the accounts of FMC and all entities that we directly or indirectly control. All significant intercompany accounts and transactions are eliminated in consolidation.
	Estimates and assumptions. In preparing the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results are likely to differ from those estimates, but we do not believe such differences will materially affect our financial position, results of operations or cash flows.
	Cash equivalents. We consider investments in all liquid debt instruments with original maturities of 3 months or less to be cash equivalents.
	Trade receivables, net of allowance. Trade receivables consist of amounts owed to us from customer sales and are recorded when revenue is recognized. The allowance for trade receivables represents our best estimate of the probable losses associated with potential customer defaults. In developing our allowance for trade receivables, we utilize a two stage process which includes calculating a general formula to develop an allowance to appropriately address the uncertainty surrounding collection risk of our entire portfolio and specific allowances for customers where the risk of collection has been reasonably identified either due to liquidity constraints or disputes over contractual terms and conditions.
	Our method of calculating the general formula consists of estimating the recoverability of trade receivables based on historical experience, current collection trends, and external business factors such as economic factors, including regional bankruptcy rates, and political factors. Our analysis of trade receivable collection risk is performed quarterly, and the allowance is adjusted accordingly. The allowance for trade receivable is $37.6 million and $30.2 million as of December 31, 2014 and 2013, respectively. The provision to the allowance for trade receivables charged against operations was $9.4 million, $5.7 million and $8.8 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Investments. Investments in companies in which our ownership interest is 50 percent or less and in which we exercise significant influence over operating and financial policies are accounted for using the equity method. Under the equity method, original investments are recorded at cost and adjusted by our share of undistributed earnings and losses of these investments. Majority owned investments in which our control is restricted are also accounted for using the equity method. All other investments are carried at their fair values or at cost, as appropriate. We are party to several joint venture investments throughout the world, which individually and in the aggregate are not significant to our financial results.
	Inventories. Inventories are stated at the lower of cost or market value. Inventory costs include those costs directly attributable to products before sale, including all manufacturing overhead but excluding distribution costs. All domestic inventories, excluding materials and supplies, are determined on a last-in, first-out (“LIFO”) basis and our remaining inventories are recorded on a first-in, first-out (“FIFO”) basis. See Note 5.
	Property, plant and equipment. We record property, plant and equipment, including capitalized interest, at cost. Depreciation is provided principally on the straight-line basis over the estimated useful lives of the assets (land improvements—20 years, buildings—20 to 40 years, and machinery and equipment—three to 18 years). Gains and losses are reflected in income upon sale or retirement of assets. Expenditures that extend the useful lives of property, plant and equipment or increase productivity are capitalized. Ordinary repairs and maintenance are expensed as incurred through operating expense.
	Capitalized interest. We capitalized interest costs of $10.2 million in 2014, $5.7 million in 2013 and $7.2 million in 2012. These costs were associated with the construction of certain long-lived assets and have been capitalized as part of the cost of those assets. We amortize capitalized interest over the assets’ estimated useful lives.
	Impairments of long-lived assets. We review the recovery of the net book value of long-lived assets whenever events and circumstances indicate that the net book value of an asset may not be recoverable from the estimated undiscounted future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the net book value, we recognize an impairment loss equal to an amount by which the net book value exceeds the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.
	Asset retirement obligations. We record asset retirement obligations at fair value at the time the liability is incurred if we can reasonably estimate the settlement date. The associated asset retirement obligations (“AROs”) are capitalized as part of the carrying amount of related long-lived assets. In future periods, the liability is accreted to its present value and the capitalized cost is depreciated over the useful life of the related asset. We also adjust the liability for changes resulting from the passage of time and/or revisions to the timing or the amount of the original estimate. Upon retirement of the long-lived asset, we either settle the obligation for its recorded amount or incur a gain or loss. See Note 8 for further discussion on our AROs.
	Restructuring and other charges. We continually perform strategic reviews and assess the return on our businesses. This sometimes results in a plan to restructure the operations of a business. We record an accrual for severance and other exit costs under the provisions of the relevant accounting guidance.
	Additionally, as part of these restructuring plans, write-downs of long-lived assets may occur. Two types of assets are impacted: assets to be disposed of by sale and assets to be abandoned. Assets to be disposed of by sale are measured at the lower of carrying amount or estimated net proceeds from the sale. Assets to be abandoned with no remaining future service potential are written down to amounts expected to be recovered. The useful life of assets to be abandoned that have a remaining future service potential are adjusted and depreciation is recorded over the adjusted useful life.
	Capitalized software. We capitalize the costs of internal use software in accordance with accounting literature which generally requires the capitalization of certain costs incurred to develop or obtain internal use software. We assess the recoverability of capitalized software costs on an ongoing basis and record write-downs to fair value as necessary. We amortize capitalized software costs over expected useful lives ranging from three to 10 years. See Note 20 for the unamortized computer software balances.
	Goodwill and intangible assets. Goodwill and other indefinite life intangible assets (“intangibles”) are not subject to amortization. Instead, they are subject to at least an annual assessment for impairment by applying a fair value-based test.
	We test goodwill and indefinite life intangibles for impairment annually using the criteria prescribed by U.S. GAAP accounting guidance for goodwill and other intangible assets. We did not record any goodwill or indefinite life intangible impairments to continuing operations in 2014, 2013 and 2012. Based upon our annual impairment assessment, conducted in 2014, we believe that the fair value of our reporting units with goodwill substantially exceeds their carrying value.
	Finite-lived intangible assets consist primarily of patents, access rights, customer relationships, brands, registration rights, industry licenses, developed formulations and other intangibles and are being amortized over periods of five to 25 years. See Note 4 for additional information on goodwill and intangible assets.
	Revenue recognition. We recognize revenue when the earnings process is complete, which is generally upon transfer of title. This transfer typically occurs either upon shipment to the customer or upon receipt by the customer. In all cases, we apply the following criteria in recognizing revenue: persuasive evidence of an arrangement exists, delivery has occurred, the selling price is fixed or determinable and collection is reasonably assured. Rebates due to customers are accrued as a reduction of revenue in the same period that the related sales are recorded based on the contract terms.
	We periodically enter into prepayment arrangements with customers, primarily in our FMC Agricultural Solutions segment, and receive advance payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue and classified as “Advance payments from customers” on the consolidated balance sheet. Revenue associated with advance payments is recognized as shipments are made and title, ownership and risk of loss pass to the customer.
	We record amounts billed for shipping and handling fees as revenue. Costs incurred for shipping and handling are recorded as costs of sales and services. Amounts billed for sales and use taxes, value-added taxes, and certain excise and other specific transactional taxes imposed on revenue-producing transactions are presented on a net basis and excluded from sales in the consolidated income statements. We record a liability until remitted to the respective taxing authority.
	Research and Development. Research and development costs are expensed as incurred. In-process research and development acquired as part of asset acquisitions, which include license and development agreements, are expensed as incurred and included as a component of “Restructuring and other charges (income)”.
	Income and other taxes. We provide current income taxes on income reported for financial statement purposes adjusted for transactions that do not enter into the computation of income taxes payable and recognize deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. We do not provide income taxes on the equity in undistributed earnings of consolidated foreign subsidiaries as it is our intention that such earnings will remain invested in those companies.
	Foreign currency. We translate the assets and liabilities of our foreign operations at exchange rates in effect at the balance sheet date. For foreign operations for which the functional currency is not the U.S. dollar we record translation gains and losses as a component of accumulated other comprehensive income in equity. The foreign operations' income statements are translated at the monthly exchange rates for the period.
	We record remeasurement gain and losses on monetary assets and liabilities, such as accounts receivables and payables, which are not in the functional currency of the operation. These remeasurement gains and losses are recorded in the income statement as they occur. We generally enter into foreign currency contracts to mitigate the financial risk associated with these transactions.  See “Derivative financial instruments” below and Note 17.
	Derivative financial instruments. We mitigate certain financial exposures, including currency risk, interest rate risk and commodity price exposures, through a controlled program of risk management that includes the use of derivative financial instruments. We enter into foreign exchange contracts, including forward and purchased option contracts, to reduce the effects of fluctuating foreign currency exchange rates.
	We recognize all derivatives on the balance sheet at fair value. On the date the derivative instrument is entered into, we generally designate the derivative as either a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge) or a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge). We record in accumulated other comprehensive income or loss changes in the fair value of derivatives that are designated as, and meet all the required criteria for, a cash flow hedge. We then reclassify these amounts into earnings as the underlying hedged item affects earnings. We record immediately in earnings changes in the fair value of derivatives that are not designated as cash flow hedges.
	We formally document all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. This process includes relating derivatives that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. We also formally assess, both at the inception of the hedge and throughout its term, whether each derivative is highly effective in offsetting changes in fair value or cash flows of the hedged item. If we determine that a derivative is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, we discontinue hedge accounting with respect to that derivative prospectively.
	Treasury stock. We record shares of common stock repurchased at cost as treasury stock, resulting in a reduction of stockholders’ equity in the Consolidated Balance Sheets. When the treasury shares are contributed under our employee benefit plans or issued for option exercises, we use a first-in, first-out (“FIFO”) method for determining cost. The difference between the cost of the shares and the market price at the time of contribution to an employee benefit plan is added to or deducted from the related capital in excess of par value of common stock.
	Segment information. We determined our reportable segments based on our strategic business units, the commonalities among the products and services within each segment and the manner in which we review and evaluate operating performance.
	We have identified FMC Agricultural Solutions, FMC Health and Nutrition and FMC Minerals as our reportable segments. Segment disclosures are included in Note 19. Segment operating profit is defined as segment revenue less segment operating expenses (segment operating expenses consist of costs of sales and services, selling, general and administrative expenses and research and development expenses). We have excluded the following items from segment operating profit: corporate staff expense, interest income and expense associated with corporate debt facilities and investments, income taxes, gains (or losses) on divestitures of businesses, restructuring and other charges (income), investment gains and losses, loss on extinguishment of debt, asset impairments, LIFO inventory adjustments, acquisition related costs, non-operating pension and postretirement charges, and other income and expense items. Information about how restructuring and other charges (income) relate to our businesses at the segment level is discussed in Note 7.
	Segment assets and liabilities are those assets and liabilities that are recorded and reported by segment operations. Segment operating capital employed represents segment assets less segment liabilities. Segment assets exclude corporate and other assets, which are principally cash equivalents, the LIFO reserve on inventory, deferred income taxes, eliminations of intercompany receivables and property and equipment not attributable to a specific segment, such as capitalized interest. Segment liabilities exclude substantially all debt, income taxes, pension and other postretirement benefit liabilities, environmental reserves and related recoveries, restructuring reserves, fair value of currency contracts, intercompany eliminations, and reserves for discontinued operations.
	Geographic segment revenue is based on the location of our customers. Geographic segment long-lived assets include investments, net property, plant and equipment, and other non-current assets. Geographic segment data is included in Note 19.
	Stock compensation plans. We recognize compensation expense in the financial statements for all share options and other equity-based arrangements. Share-based compensation cost is measured at the date of grant, based on the fair value of the award, and is recognized over the employee’s requisite service period. See Note 14 for further discussion on our share-based compensation.
	Environmental obligations. We provide for environmental-related obligations when they are probable and amounts can be reasonably estimated. Where the available information is sufficient to estimate the amount of liability, that estimate has been used. Where the information is only sufficient to establish a range of probable liability and no point within the range is more likely than any other, the lower end of the range has been used.
	Estimated obligations to remediate sites that involve oversight by the United States Environmental Protection Agency (“EPA”), or similar government agencies, are generally accrued no later than when a Record of Decision (“ROD”), or equivalent, is issued, or upon completion of a Remedial Investigation/Feasibility Study (“RI/FS”), or equivalent, that is submitted by us and the appropriate government agency or agencies. Estimates are reviewed quarterly and, if necessary, adjusted as additional information becomes available. The estimates can change substantially as additional information becomes available regarding the nature or extent of site contamination, required remediation methods, and other actions by or against governmental agencies or private parties.
	Our environmental liabilities for continuing and discontinued operations are principally for costs associated with the remediation and/or study of sites at which we are alleged to have released hazardous substances into the environment. Such costs principally include, among other items, RI/FS, site remediation, costs of operation and maintenance of the remediation plan, management costs, fees to outside law firms and consultants for work related to the environmental effort, and future monitoring costs. Estimated site liabilities are determined based upon existing remediation laws and technologies, specific site consultants’ engineering studies or by extrapolating experience with environmental issues at comparable sites.
	Included in our environmental liabilities are costs for the operation, maintenance and monitoring of site remediation plans ("OM&M"). Such reserves are based on our best estimates for these OM&M plans. Over time we may incur OM&M costs in excess of these reserves. However, we are unable to reasonably estimate an amount in excess of our recorded reserves because we cannot reasonably estimate the period for which such OM&M plans will need to be in place or the future annual cost of such remediation, as conditions at these environmental sites change over time. Such additional OM&M costs could be significant in total but would be incurred over an extended period of years.
	Included in the environmental reserve balance, other assets balance and disclosure of reasonably possible loss contingencies are amounts from third party insurance policies which we believe are probable of recovery.
	Provisions for environmental costs are reflected in income, net of probable and estimable recoveries from named Potentially Responsible Parties (“PRPs”) or other third parties. Such provisions incorporate inflation and are not discounted to their present values.
	In calculating and evaluating the adequacy of our environmental reserves, we have taken into account the joint and several liability imposed by Comprehensive Environmental Remediation, Compensation and Liability Act (“CERCLA”) and the analogous state laws on all PRPs and have considered the identity and financial condition of the other PRPs at each site to the extent possible. We have also considered the identity and financial condition of other third parties from whom recovery is anticipated, as well as the status of our claims against such parties. Although we are unable to forecast the ultimate contributions of PRPs and other third parties with absolute certainty, the degree of uncertainty with respect to each party is taken into account when determining the environmental reserve on a site-by-site basis. Our liability includes our best estimate of the costs expected to be paid before the consideration of any potential recoveries from third parties. We believe that any recorded recoveries related to PRPs are realizable in all material respects. Recoveries are recorded as either an offset in “Environmental liabilities, continuing and discontinued” or as “Other assets” in our consolidated balance sheets in accordance with U.S. accounting literature.
	Pension and other postretirement benefits. We provide qualified and nonqualified defined benefit and defined contribution pension plans, as well as postretirement health care and life insurance benefit plans to our employees and retirees. The costs (or benefits) and obligations related to these benefits reflect key assumptions related to general economic conditions, including interest (discount) rates, healthcare cost trend rates, expected rates of return on plan assets and the rates of compensation increase for employees. The costs (or benefits) and obligations for these benefit programs are also affected by other assumptions, such as average retirement age, mortality, employee turnover, and plan participation. To the extent our plans’ actual experience, as influenced by changing economic and financial market conditions or by changes to our own plans’ demographics, differs from these assumptions, the costs and obligations for providing these benefits, as well as the plans’ funding requirements, could increase or decrease. When actual results differ from our assumptions, the difference is typically recognized over future periods. In addition, the unrealized gains and losses related to our pension and postretirement benefit obligations may also affect periodic benefit costs (or benefits) in future periods. See Note 13 for additional information relating to pension and other postretirement benefits.
	Reclassifications. Certain prior year amounts have been reclassified to conform with current year's presentation.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued and Adopted Accounting Pronouncements and Regulatory Items	Recently Issued and Adopted Accounting Pronouncements and Regulatory Items
	New Accounting guidance and regulatory items
	In February 2015, the Financial Accounting Standards Board ("FASB") issued ASU 2015-02, Consolidation: Amendments to the Consolidation Analysis. This new standard changes the consolidation evaluation for entities that are required to evaluate whether they should consolidate certain legal entities. We are required to adopt this standard in the first quarter of 2016. Early adoption is permitted. The standard permits the use of a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption, or a reporting entity may also apply the amendments retrospectively. We are evaluating the effect that ASU 2015-02 will have on our consolidated financial statements. We have not yet completed the assessment to determine the effect of the standard on our ongoing financial reporting.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This new guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. We are required to adopt this standard on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
	In April 2014, the FASB issued its updated guidance on the financial reporting of discontinued operations. This new standard changes the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Additionally, expanded disclosures about discontinued operations will be required to provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This guidance impacts disclosures within an entity's financial statements and notes to the financial statements. We are required to adopt this guidance prospectively in the first quarter of 2015. The updated guidance will not impact existing conclusions with respect to discontinued operations classification.

Business Combinations [Abstract]
Acquisitions	Acquisitions
	2014 Acquisitions:
	Cheminova A/S:
	On September 8, 2014, we entered into a definitive Share Purchase Agreement (the "Purchase Agreement") with Auriga Industries A/S, a Denmark Aktieselskab ("Aurgia") and Cheminova A/S, a Denmark Aktieselskab, a wholly owned subsidiary of Auriga ("Cheminova"). Pursuant to the terms and conditions set forth in the Purchase Agreement, we have agreed to acquire all of the outstanding equity of Cheminova from Auriga for an aggregate purchase price of 8.5 billion Danish Krone or approximately $1.4 billion, excluding net debt to be assumed of approximately $0.3 billion (the “Acquisition”) as of December 31, 2014. We expect to complete the Acquisition in early 2015.
	Also, on September 8, 2014, in connection with the Purchase Agreement, we entered into a commitment letter (the "Commitment Letter") with Citigroup Global Markets Inc. (collectively with certain of its affiliates, the “Commitment Party”). The Commitment Letter provided that, in connection with the Acquisition and subject to the conditions set forth in the Commitment Letter, the Commitment Party will commit to provide up to a $2.0 billion 364-day bridge term loan and a $1.5 billion revolving credit facility to FMC to replace the existing revolving credit facility. Fees incurred to secure these commitments have been deferred with amortization over the term of the arrangement.
	On October 10, 2014, the financing available under the Commitment Letter was terminated and replaced by a $2.0 billion term loan facility and an amended and restated $1.5 billion revolving credit facility. Approximately $4.3 million of the deferred fees associated with the Commitment Letter were expensed and presented within selling, general and administrative within our consolidated statements of income consistent with other acquisition-related costs. The remaining fees have been capitalized in combination with the term loan facility. The details of the term loan facility and the revolving credit facility are provided in Note 12 within these consolidated financial statements.
	Charges incurred for the twelve months ended December 31, 2014 associated with the Acquisition which include the unrealized loss on the hedge of the purchase price are provided in Note 19 within these consolidated financial statements.
	Noncontrolling interest purchase:
	In October 2014 we purchased the remaining 6.25% ownership interest from the last remaining non-controlling interest holder in a legal entity within our FMC Alkali Chemicals division. See Note 15 for more information.
	2013 Acquisitions
	Epax:
	In July 2013, we acquired 100 percent of the stock of Epax Nutra Holding III AS and Epax UK Holding III AS (together, “Epax”) for $339.6 million. Epax is a global supplier of fish-based omega-3 EPA/DHA fatty acid concentrates. Epax was integrated into our FMC Health and Nutrition segment from the acquisition date.
	The results of operations related to Epax have been included in our results since the acquisition date. This acquisition was considered a business under the U.S. GAAP business combinations accounting guidance, and therefore we applied acquisition accounting. Acquisition accounting requires, among other things, that assets and liabilities assumed be recognized at their fair values as of the acquisition date. The net assets of the Epax acquisition were recorded at the estimated fair values using primarily Level 2 and Level 3 inputs (see Note 17 for an explanation of Level 2 and 3 inputs). In valuing acquired assets and liabilities, valuation inputs include an estimate of future cash flows and discount rates based on the internal rate of return and the weighted average rate of return. Transaction-related costs of approximately $4.8 million were expensed as incurred and recorded to "Selling, general and administrative expenses" within our consolidated statements of income.

	-2	The major classes of intangible assets acquired primarily represent customer relationships and brands. The weighted average useful life of the acquired finite-lived intangibles is approximately 17 years. See Note 4 for more information.
	-3	Goodwill largely consisted of expected revenue synergies resulting from the business combinations. None of the acquired goodwill will be deductible for income tax purposes.
	Noncontrolling interest purchase:
	In 2013, we completed the purchase of additional ownership interest in a legal entity within our FMC Alkali Chemicals division. See Note 15 for more information.
	2012 Acquisitions
	GAT Microencapsulation AG:
	In December 2012, we signed a perpetual, global licensing agreement, along with distribution and services agreements with GAT Microencapsulation AG covering a range of advanced crop protection products and proprietary formulation technologies. The acquired assets have been integrated into our FMC Agricultural Solutions segment.
	Pectine Italia S.p.A.:
	In August 2012, we acquired the assets of Pectine Italia S.p.A. (PI). PI produces pectin, a well known stabilizer and thickening agent used widely in many foods and derived predominately from lemon peels. The company has production facilities in Milazzo, on the island of Sicily. The acquired assets of PI are reported as part of our FMC Health and Nutrition segment.
	Phytone Ltd.:
	In June 2012, we acquired 100 percent of the stock of Phytone Ltd. (Phytone). Phytone is a natural colors producer based in the United Kingdom. Phytone's natural products and formulations are used by global customers in the food, beverage, personal care and nutrition sectors. Phytone has been consolidated into our existing FMC Health and Nutrition segment.
	The total purchase price for the three 2012 acquisitions was $117.4 million. During the year ended December 31, 2013 we finalized the purchase price allocation of the 2013 acquisitions which did not result in any additional payments. The final purchase price for the 2012 acquisitions was primarily allocated to goodwill of $62.4 million, property, plant and equipment of $27.7 million and identifiable intangible assets of $38.8 million.
	Unaudited pro forma revenue and net income related to all of the closed acquisitions discussed above are not presented because the pro forma impact is not material.

	2014 Restructuring Activities
	Health and Nutrition Restructuring
	In 2014 our FMC Health and Nutrition segment implemented a plan to restructure a portion of its operations. The objective of the restructuring was to better align our business and costs to macroeconomic and market realities. The restructuring decision resulted in workforce reductions at several of our FMC Health and Nutrition facilities.
	Other Items
	In addition to the restructurings described above, we have engaged in certain other restructuring activities, which have resulted in severance and asset disposal costs. We expect these restructuring activities to improve our global competitiveness through improved cost efficiencies.

	During 2014 and 2013 our FMC Agricultural Solutions segment entered into collaboration and license agreements with various third-party companies for the purpose of obtaining certain technology and intellectual property rights relating to new compounds still under development. Specifically in 2014 we entered into one transaction consisting of an exclusive license, development and supply arrangements for a novel crop protection product for agricultural use in the United States. During 2013 we entered into three such transactions, consisting of: exclusive license and supply arrangements for a broad-spectrum crop protection product and an acquisition of certain intellectual property and other assets relating to biological products associated with our acquired assets of the Center for Agricultural and Environmental Biosolutions (CAEB). CAEB is based in Research Triangle Park, NC, and amounts acquired include CAEB’s robust library of microorganisms and a pipeline of biological products in various stages of development. The rights and technology obtained is referred to as in-process research and development and in accordance with GAAP, the amounts paid were expensed as incurred since they were acquired outside of a business combination.
	In 2014 we sold portion of our ownership interest in a Belgium-based pesticide distribution company, Belchim Crop Protection N.V. ("Belchim"). Prior to and subsequent to the sale, Belchim was accounted for as a cost method investment. The gain on the sale of approximately $26.6 million was recorded as "Other income, net".

Asset Retirement Obligation Disclosure	Asset Retirement Obligations
	We have mining operations in Green River, Wyoming for our soda ash business as well as mining operations in our lithium operations. We have legal reclamation obligations related to these facilities upon closure of the mines. Additionally, we have obligations at the majority of our manufacturing facilities in the event of a permanent plant shutdown. Certain of these obligations are recorded in our environmental reserves described in Note 10. For certain AROs not already accrued, we have calculated the fair value of these AROs and concluded that the present value of these obligations was immaterial at December 31, 2014 and 2013. We have also determined that the liability for certain other AROs cannot currently be calculated as the settlement dates are not reasonably estimable. We will recognize the liability for these AROs when sufficient information exists to estimate a range of potential settlement dates.
	The changes in the carrying amounts of AROs for the years ended December 31, 2014 and 2013 are as follows:

	FMC Peroxygens:
	On February 28, 2014, we completed the sale of our FMC Peroxygens business for $199.1 million in cash to One Equity Partners (OEP), the private investment arm of J.P. Morgan Chase & Co. The sale resulted in approximately $198.6 million in after-tax proceeds and a final pre-tax loss of $10.1 million ($33.4 million after-tax) for the twelve months ended December 31, 2014. The after-tax loss of $33.4 million was driven by the allocation of the $199.1 million of proceeds which was agreed to between us and OEP. The majority of the proceeds were allocated to higher taxing jurisdictions (i.e., United States) which resulted in tax expense within those jurisdictions, that were not offset by tax benefits from other taxing jurisdictions. We did not benefit the tax losses produced in those other taxing jurisdictions, as we do not expect the losses produced in those jurisdictions to be recoverable. The loss was recorded in discontinued operations, net of income taxes in our consolidated income statements for the year ended December 31, 2014.
	The results of our discontinued FMC Peroxygens operations are summarized below:

Environmental Remediation Obligations [Abstract]
Environmental Obligations	Environmental Obligations
	We are subject to various federal, state, local and foreign environmental laws and regulations that govern emissions of air pollutants, discharges of water pollutants, and the manufacture, storage, handling and disposal of hazardous substances, hazardous wastes and other toxic materials and remediation of contaminated sites. We are also subject to liabilities arising under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and similar state laws that impose responsibility on persons who arranged for the disposal of hazardous substances, and on current and previous owners and operators of a facility for the clean-up of hazardous substances released from the facility into the environment. We are also subject to liabilities under the Resource Conservation and Recovery Act (“RCRA”) and analogous state laws that require owners and operators of facilities that have treated, stored or disposed of hazardous waste pursuant to a RCRA permit to follow certain waste management practices and to clean up releases of hazardous substances into the environment associated with past or present practices. In addition, when deemed appropriate, we enter certain sites with potential liability into voluntary remediation compliance programs, which are also subject to guidelines that require owners and operators, current and previous, to clean up releases of hazardous substances into the environment associated with past or present practices.
	Environmental liabilities consist of obligations relating to waste handling and the remediation and/or study of sites at which we are alleged to have released or disposed of hazardous substances. These sites include current operations, previously operated sites, and sites associated with discontinued operations. We have provided reserves for potential environmental obligations that we consider probable and for which a reasonable estimate of the obligation can be made. Accordingly, total reserves of $296.2 million and $225.7 million, respectively, before recoveries, existed at December 31, 2014 and 2013.
	The estimated reasonably possible environmental loss contingencies, net of expected recoveries, exceed amounts accrued by approximately $210 million at December 31, 2014. This reasonably possible estimate is based upon information available as of the date of the filing and the actual future losses may be higher given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of potentially responsible parties, technology and information related to individual sites.
	Additionally, although potential environmental remediation expenditures in excess of the reserves and estimated loss contingencies could be significant, the impact on our future consolidated financial results is not subject to reasonable estimation due to numerous uncertainties concerning the nature and scope of possible contamination at many sites, identification of remediation alternatives under constantly changing requirements, selection of new and diverse clean-up technologies to meet compliance standards, the timing of potential expenditures and the allocation of costs among Potentially Responsible Parties ("PRPs") as well as other third parties. The liabilities arising from potential environmental obligations that have not been reserved for at this time may be material to any one quarter's or year's results of operations in the future. However, we believe any liability arising from such potential environmental obligations is not likely to have a material adverse effect on our liquidity or financial condition as it may be satisfied over many years.
	The table below is a roll forward of our total environmental reserves, continuing and discontinued, from December 31, 2011 to December 31, 2014.

	-1	Based on events that occurred during the year ended December 31, 2014, the remaining activities associated with these obligations are primarily environmental remediation in nature and therefore the cost was transferred to environmental obligations.
	To ensure we are held responsible only for our equitable share of site remediation costs, we have initiated, and will continue to initiate, legal proceedings for contributions from other PRPs. At December 31, 2014 and 2013, we have recorded recoveries representing probable realization of claims against U.S. government agencies, insurance carriers and other third parties. Recoveries are recorded as either an offset to the “Environmental liabilities, continuing and discontinued” or as “Other assets” on the consolidated balance sheets.

Significant Environmental Sites
Front Royal
This discontinued manufacturing site, built in 1940 by American Viscose, was once one of the world's largest producers of rayon, an instrumental product for NASA's space shuttle program. The facility also made tire cord, parachutes and jump suits for the Department of War during World War II. We purchased the plant in 1963 and sold it in 1976 to Avtex Fibers Corporation. In 1989, this Avtex site was cited for violations of Virginia environmental laws, associated primarily with wastewater discharges into the Shenandoah River and was subsequently shut down. We, as the sole surviving owner of the plant, became the mandated “potentially responsible party” for cleanup purposes.
On October 21, 1999, the Federal District Court for the Western District of Virginia approved a Consent Decree signed by FMC, the EPA (Region III) and the Department of Justice ("DOJ") regarding past response costs and future clean-up work at this site. In January 2010, the EPA issued a Record of Decision ("ROD") for Operable Unit 7 ("OU-7") primarily addressing waste basins and ground water, which should be the last operable unit to be remediated at the site. Included in our reserves for this site is the cost associated with a groundwater treatment plant which is an integral component of the remedy required to address the OU-7 ROD. This groundwater treatment plant was completed in 2014. As part of a prior settlement, government agencies have reimbursed us for approximately one-third of the clean-up costs due to the government's role at the site, and we expect reimbursement to continue in the future. The amount of the reserve for this site was $16.9 million and $25.6 million at December 31, 2014 and 2013, respectively.
Pocatello
From 1949 until 2001, we operated the world's largest elemental phosphorus plant in Power County, Idaho, just outside the city of Pocatello. Since the plant's closure, FMC has worked with the EPA, the State of Idaho, and the Shoshone-Bannock Tribes to develop a proposed cleanup plan for the property. In September of 2012, the EPA issued an Interim Record of Decision ("IROD") that is environmentally protective and that ensures the health and safety of both workers and the general public. Since the plant's closure, we have successfully decommissioned our Pocatello plant, completed closure of the RCRA ponds and formally requested that the EPA acknowledge completion of work under a June 1999 RCRA Consent Decree. Future remediation costs include completion of the IROD that addresses groundwater contamination and existing waste disposal areas on the Pocatello plant portion of the Eastern Michaud Flats Superfund Site. In June 2013 EPA issued a Unilateral Administrative Order to us under which we will implement the IROD remedy. Our current reserves factor in the estimated costs associated with implementing the IROD. In addition to implementing the IROD, we continue to conduct work pursuant to CERCLA unilateral administrative orders to address air emissions from beneath the cap of several of the closed RCRA ponds.
The amount of the reserve for this site was $68.6 million and $61.3 million at December 31, 2014 and 2013, respectively.
Pocatello Tribal Litigation
For a number of years, we engaged in disputes with the Tribes concerning their attempts to regulate our activities on the reservation. On March 6, 2006, a U.S. District Court Judge found that the Tribes were a third-party beneficiary of a 1998 RCRA Consent Decree and ordered us to apply for any applicable Tribal permits relating to the nearly-complete RCRA Consent Decree work. The third-party beneficiary ruling was later reversed by the Ninth Circuit Court of Appeals, but the permitting process continued in the tribal legal system. We applied for the tribal permits, but preserved objections to the Tribes' jurisdiction.
In addition, in 1998, the Tribes and we entered into an agreement (“1998 Agreement”) that required us to pay the Tribes $1.5 million per year for waste generated from operating our Pocatello plant and stored on site. We paid $1.5 million per year until December 2001 when the plant closed. In our view the agreement was terminated, as the plant was no longer generating waste. The Tribes claim that the 1998 Agreement has no end date.
On April 25, 2006, the Tribes' Land Use Policy Commission issued us a Special Use Permit for the “disposal and storage of waste” at the Pocatello plant and imposed a $1.5 million per annum permit fee. The permit and fee were affirmed by the Tribal Business Council on July 21, 2006. We sought review of the permit and fee in Tribal Court, in which the Tribes also brought a claim for breach of the 1998 Agreement. On May 21, 2008, the Tribal Court reversed the permit and fee, finding that they were not authorized under tribal law, and dismissed the Tribes' breach of contract claim. The Tribes appealed to the Tribal Court of Appeals.
On May 8, 2012, the Tribal Court of Appeals reversed the May 21, 2008 Tribal Court decision and issued a decision finding the permit and fee validly authorized and ordering us to pay waste permit fees in the amount of $1.5 million per annum for the years 2002-2007 ($9.0 million in total), the Tribes' demand as set forth in the lawsuit. It also reinstated the breach of contract claim. The Tribes have filed additional litigation to recover the permit fees for the years since 2007, but that litigation has been stayed pending the outcome of the appeal in the Tribal Court of Appeals.
Following a trial on certain jurisdictional issues which occurred during April 2014, the Shoshone-Bannock Tribal Appellate Court issued a Statement of Decision finding in favor of the Tribes’ jurisdiction over FMC and awarding costs on appeal to the Tribes. The Tribal Appellate Court conducted further post-trial proceedings and on May 6, 2014 issued Finding and Conclusions and a Final Judgment consistent with its earlier Statement of Decision.
The finding by the Shoshone-Bannock Tribal Appellate Court in May 2014 does not impact our reserves for the period ended December 31, 2014. Having now exhausted the Tribal administrative and judicial process, in November 2014 we filed an action in the United States District Court seeking declaratory and injunctive relief on the grounds that the Tribes lacked jurisdiction over us.
We have estimated a reasonably possible loss for this matter and it has been reflected in our total reasonably possible loss estimate previously discussed within this note.
Middleport
Our Middleport, NY facility is currently an Agricultural Solutions formulation and packaging plant that formerly manufactured arsenic-based and other products. As a result of past manufacturing operations and waste disposal practices at this facility, releases of hazardous substances have occurred at the the site that have affected soil, sediment, surface water and groundwater at the facility's property and also in adjacent off-site areas. The impact of our discontinued operations was the subject of an Administrative Order on Consent (“AOC”) entered into with the EPA and New York State Department of Environmental Conservation (the “Agencies”) in 1991. The AOC requires us to (1) define the nature and extent of contamination caused by our historical plant operations, (2) take interim corrective measures and (3) evaluate Corrective Action Management Alternatives (“CMA”) for discrete contaminated areas.
We have defined the nature and extent of the contamination and have constructed an engineered cover, closed the RCRA regulated surface water impoundments and are collecting and treating both surface water runoff and ground water, which has satisfied the first two requirements of the AOC.
In 2013 we received from the New York State Department of Environmental Conservation ("NYSDEC"), the Final Statement of Basis ("FSOB"). The FSOB includes the same CMA as the Preliminary Statement of Basis, which we continue to believe is overly conservative and is not consistent with the 1991 AOC, which governs the remedy selection.
In order to negotiate with the NYSDEC with respect to the FSOB, we entered into a tolling agreement with the NYSDEC. The tolling agreement serves as a “standstill” agreement to the FSOB so that time spent negotiating with the NYSDEC does not go against the statute of limitations under the FSOB. The tolling agreement expired on April 30, 2014. We were not able to reach an agreement with the NYSDEC; thus, on May 1, 2014, we submitted a Notice of Dispute to the EPA seeking review of the remedy chosen by the NYSDEC. On May 30, 2014, 30 days after the tolling period expired, we filed an action in the Supreme Court of New York formally challenging the NYSDEC's FSOB. In that lawsuit, we are contending that NYSDEC breached the 1991 AOC by not following the procedures set forth in the AOC for remedy selection. On June 3, 2014, we received a letter from EPA (dated May 22, 2014) declining to review the Notice of Dispute. On June 20, 2014, we filed an action in the United States District Court for the Western District of New York seeking a declaratory judgment that the EPA is obligated under the 1991 AOC to hear the dispute.
The amount of the reserve for this site is $44.9 million and $41.7 million at December 31, 2014 and 2013, respectively. Our reserve continues to include the estimated liability for clean-up to reflect the costs associated with our recommended CMA. Our estimated reasonably possible environmental loss contingencies exposure reflects the additional cost of the CMA proposed in the FSOB.
Other Potentially Responsible Party (“PRP”) Sites
We have been named a PRP at 32 sites on the federal government’s National Priorities List (“NPL”), at which our potential liability has not yet been settled. In addition, we received notice from the EPA or other regulatory agencies that we may be a PRP, or PRP equivalent, at other sites, including 37 sites at which we have determined that it is reasonably possible that we have an environmental liability. In cooperation with appropriate government agencies, we are currently participating in, or have participated in, a Remedial Investigation/Feasibility Study (“RI/FS”), or equivalent, at most of the identified sites, with the status of each investigation varying from site to site. At certain sites, a RI/FS has only recently begun, providing limited information, if any, relating to cost estimates, timing, or the involvement of other PRPs; whereas, at other sites, the studies are complete, remedial action plans have been chosen, or a ROD has been issued.
One site where FMC is listed as a PRP is the Portland Harbor Superfund Site (“Portland Harbor”), that includes the river and sediments of a 12 mile section of the lower reach of the Willamette River in Portland, Oregon that runs through an industrialized area. Portland Harbor is listed on the NPL. FMC formerly owned and operated a manufacturing site adjacent to this section of the river and has since sold its interest in this business. When the EPA determines the cleanup remedy from the RI/FS conducted during the last decade at the site, it will issue a ROD. Currently, FMC and 70 other parties including the current owner of the former FMC site are involved in a non-judicial allocation process to determine each party’s respective share of the cleanup costs. The EPA is expected to develop a ROD by 2017. It is anticipated that the cleanup activities will begin within one year of the issuance of the ROD.
Any potential liability to FMC will represent a portion of the costs of the remedy the EPA is expected to select for Portland Harbor. The cost of that remedy is expected to be allocated among more than 70 potentially responsible parties. Because of the large number of responsible parties and the variability in range of remediation alternatives, we are unable to develop a reasonable estimate of our potential exposure for Portland Harbor at this time. Based on information currently available, we have no reason to believe that the ultimate resolution of our potential obligations at Portland Harbor will have a material adverse effect on our consolidated financial position, liquidity or results of operations. However, there can be no assurance that the outcome will be favorable. Adverse results in the outcome of the EPA decision could have a material adverse effect on our consolidated financial position, results of operations in any one reporting period, or liquidity.

		Year Ended December 31,
	(in Millions)	2014				2013				2012
	Deferred tax (exclusive of valuation allowance)	$	(61.8	)		$	19.4			$	68.8

	Deferred income tax provision	$	(61.0	)		$	19.6			$	55.1
	We have recognized that it is more likely than not that certain future tax benefits may not be realized through future taxable income. During the year ended December 31, 2014, the valuation allowance change was due to $1.7 million of tax losses incurred by certain foreign operations that are not expected to be recoverable, partially offset by a $0.9 million release primarily due to state net operating losses now expected to be recoverable. During the year ended December 31, 2013, the valuation allowance change was due to $2.1 million of tax losses incurred by certain foreign operations that are not expected to be recoverable, partially offset by a $1.9 million release primarily due to state net operating losses now expected to be recoverable. During the year ended December 31, 2012, the decrease was primarily due to a release of $14.9 million related to state net operating losses expected to be recoverable, partially offset by a $1.2 million provision due to tax losses of foreign operations that are not expected to be recoverable.
	Significant components of our deferred tax assets and liabilities were attributable to:

	Net deferred tax assets	$	368.8			$	232.3
	____________________
	-1	The change in the net valuation allowance was primarily driven by our FMC Peroxygens' foreign operations which are classified as discontinued operations.
	We evaluate our deferred income taxes quarterly to determine if valuation allowances are required or should be adjusted. U.S. GAAP accounting guidance requires that companies assess whether valuation allowances should be established against their deferred tax assets based on all available evidence, both positive and negative, using a “more likely than not” standard. In assessing the need for a valuation allowance, appropriate consideration is given to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, and tax planning alternatives. We operate and derive income from multiple lines of business across multiple jurisdictions. As each of the respective lines of business experiences changes in operating results across their geographic footprint, we may encounter losses in jurisdictions that have been historically profitable, and as a result might require additional valuation allowances to be recorded. We are committed to implementing tax planning actions, when deemed appropriate, in jurisdictions that experience losses in order to realize deferred tax assets prior to their expiration.
	At December 31, 2014, we had net operating loss and tax credit carryforwards as follows: U.S. state net operating loss carryforwards of $17.3 million (tax-effected) expiring in future years through 2027, foreign net operating loss carryforwards of $125.7 million (tax-effected) expiring in various future years, U.S. foreign tax credit carryforwards of $1.1 million expiring in 2015 and foreign tax credit carryforwards of $6.3 million expiring in various future years.
	The effective income tax rate applicable to income from continuing operations before income taxes was different from the statutory U.S. federal income tax rate due to the factors listed in the following table:
		Year Ended December 31,
		2014			2013			2012
	Statutory U.S. tax rate	35	%		35	%		35	%
	Net difference:
	Percentage depletion	(4.5	)		(3.4	)		(3.5	)
	State and local income taxes, less federal income tax benefit	0.8			2.2			1.1
	Foreign earnings subject to different tax rates	(17.3	)		(11.3	)		(7.3	)
	Manufacturer’s production deduction and miscellaneous tax credits	(1.6	)		(1.1	)		(1.3	)
	Tax on intercompany dividends and deemed dividend for tax purposes	2.2			0.6			0.4
	Nondeductible expenses	1.3			0.4			0.4
	Changes to unrecognized tax benefits	1			0.9			(0.3	)
	Change in valuation allowance	0.2			—			(1.6	)
	Other	(1.9	)		0.8			(0.4	)
	Total difference	(19.8	)		(10.9	)		(12.5	)
	Effective tax rate	15.2	%		24.1	%		22.5	%
	Unremitted earnings of foreign subsidiaries for which we have not provided taxes approximate $1,638.1 million. We have not provided taxes for these earnings given that our intention, as of December 31, 2014, is to indefinitely reinvest such earnings in the respective existing foreign operations. We have not provided deferred tax liabilities for basis differences in investments in subsidiaries because the investments are essentially permanent in duration or we have concluded that no additional tax liability will arise upon disposal. A liability may arise in the future if our intention to indefinitely reinvest such earnings were to change, however it is not practical to estimate the income tax liability that may be incurred.
Uncertain Income Tax Positions
U.S. GAAP accounting guidance for uncertainty in income taxes prescribes a model for the recognition and measurement of a tax position taken or expected to be taken in a tax return, and provides guidance on derecognition, classification, interest and penalties, disclosure and transition.
We file income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. The income tax returns for FMC entities taxable in the U.S. and significant foreign jurisdictions are open for examination and adjustment. As of December 31, 2014, the U. S. federal and state income tax returns are open for examination and adjustment for the years 2011-2014 and 2004-2014, respectively. Our significant foreign jurisdictions, which total 19, are open for examination and adjustment during varying periods from 2004-2014.
The total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate was $15.5 million and $10.8 million as of December 31, 2014 and December 31, 2013, respectively. Interest and penalties related to unrecognized tax benefits are reported as a component of income tax expense. For the years ended December 31, 2014, December 31, 2013, and December 31, 2012 we recognized interest and penalties of $1.0 million, $2.1 million, and $0.1 million respectively, in the consolidated statements of income. As of December 31, 2014 and December 31, 2013, we have accrued interest and penalties in the consolidated balance sheets of $3.2 million and $2.2 million, respectively.
Due to the potential for resolution of federal, state, or foreign examinations, and the expiration of various jurisdictional statutes of limitation, it is reasonably possible that our liability for gross unrecognized tax benefits will decrease within the next 12 months by a range of $3.7 million to $2.5 million.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
(in Millions)	2014				2013				2012
Balance at beginning of year	$	37.3			$	23.3			$	8.1
Additions for the current year	9.9				15.4				5.5

Balance at end of year (1)	$	47.1			$	37.3			$	23.3
____________________
-1	At December 31, 2014, 2013, and 2012 we recognized an offsetting non-current deferred tax asset of $34.8 million, $28.7 million, and $16.7 million respectively, relating to specific uncertain tax positions presented above.

	-1	Letters of credit outstanding under the Credit Facility totaled $89.4 million and available funds under this facility were $924.0 million at December 31, 2014 (which reflects borrowings under our commercial paper program).
	Maturities of long-term debt
	Maturities of long-term debt outstanding, excluding discounts, at December 31, 2014, are $2.0 million in 2015, $2.4 million in 2016, $2.6 million in 2017, $2.6 million in 2018, $302.6 million in 2019 and $845.3 million thereafter.
	Covenants
	Among other restrictions, the Credit Facility contains financial covenants applicable to FMC and its consolidated subsidiaries related to leverage (measured as the ratio of debt to adjusted earnings) and interest coverage (measured as the ratio of adjusted earnings to interest expense). Our actual leverage for the four consecutive quarters ended December 31, 2014 was 2.4 which is below the maximum leverage of 3.5. Our actual interest coverage for the four consecutive quarters ended December 31, 2014 was 12.9 which is above the minimum interest coverage of 3.5. We were in compliance with all covenants at December 31, 2014.
	Term Loan Facility
	On October 10, 2014, we entered into a term loan agreement (the “Term Loan Agreement”), that provides for a senior unsecured term loan facility of up to $2.0 billion (the “Term Loan Facility”) to consummate the acquisition of Cheminova (the "Acquisition"). The Term Loan Facility is a senior unsecured obligation that ranks equally with our other senior unsecured obligations. The proceeds of the loans to be made pursuant to the Term Loan Facility will be available in one or more drawings on the closing date of the Term Loan Facility, which will be substantially concurrent with the closing of the Acquisition. The scheduled maturity of the Term Loan Facility is on the fifth anniversary of this closing date. The proceeds will be used to finance the Acquisition as well as to pay fees and expenses incurred in connection with the Acquisition and the other transactions contemplated by or related to the Acquisition or the Term Loan Facility.
	Loans under the Term Loan Agreement will bear interest at a floating rate, which will be a base rate or a Eurocurrency rate equal to the London interbank offered rate for the relevant interest period, plus in each case an applicable margin, as determined in accordance with the provisions of the Term Loan Agreement. The base rate will be the highest of: the rate of interest announced publicly by Citibank, N.A. in New York, New York from time to time as its “base rate”; the federal funds effective rate plus 0.50 percent of one percent; and the Eurocurrency rate for a one-month period plus one percent.
	We are required to pay a commitment fee on the average daily unused amount from October 10, 2014 until the date on which all commitments are terminated, payable quarterly, at a rate per annum equal to an applicable percentage in effect from time to time for commitment fees. The initial commitment fee is 0.125 percent per annum. The applicable margin and the commitment fee are subject to adjustment as provided in the Term Loan Agreement.
	The Term Loan Agreement contains financial and other covenants, including a maximum leverage ratio and minimum interest coverage ratio. The Term Loan Agreement also contains a cross-default provision whereby a default under our other indebtedness in excess of $50.0 million, after grace periods and absent a waiver from the lenders, would be an event of default under the Term Loan Agreement and could result in a demand for payment of all amounts outstanding under this facility.
	Fees incurred to secure the Term Loan Facility have been deferred and will be amortized over the term of the arrangement.
	Revolving Credit Facility
	On October 10, 2014 we entered into an amended and restated credit agreement (the "Revolving Credit Agreement"). The unsecured Revolving Credit Agreement provides for a $1.5 billion revolving credit facility, with an option, subject to certain conditions and limitations, to increase the aggregate amount of the revolving credit commitments to $2.25 billion (the "Revolving Credit Facility"). The current termination date of the Revolving Credit Facility is October 10, 2019.
	Revolving loans under the Revolving Credit Facility will bear interest at a floating rate, which will be a base rate or a Eurocurrency rate equal to the London interbank offered rate for the relevant interest period, plus, in each case, an applicable margin, as determined in accordance with the provisions of the Revolving Credit Agreement. The base rate will be the highest of: the rate of interest announced publicly by Citibank, N.A. in New York, New York from time to time as its “base rate”; the federal funds effective rate plus 0.50 percent of one percent; and the Eurocurrency rate for a one-month period plus one percent. We are also required to pay a facility fee on the average daily amount (whether used or unused) at a rate per annum equal to an applicable percentage in effect from time to time for the facility fee, as determined in accordance with the provisions of the Revolving Credit Agreement. The initial facility fee is 0.125 percent per annum. The applicable margin and the facility fee are subject to adjustment as provided in the Revolving Credit Agreement.
	The Revolving Credit Agreement contains customary financial and other covenants, including a maximum leverage ratio and minimum interest coverage ratio. The financial covenant levels have been amended in order to permit the debt incurred under the contemplated Term Loan Facility discussed above along with certain other changes to permit the Acquisition and the divestiture of our FMC Alkali Chemicals division. The Revolving Credit Agreement also contains a cross-default provision whereby a default under our other indebtedness in excess of $50.0 million, after grace periods and absent a waiver from the lenders, would be an event of default under the Revolving Credit Agreement and could result in a demand for payment of all amounts outstanding under this facility.
	Fees incurred to secure the Revolving Credit Facility have been deferred and will be amortized over the term of the arrangement.
	Compensating Balance Agreements
	We maintain informal credit arrangements in many foreign countries. Foreign lines of credit, which include overdraft facilities, typically do not require the maintenance of compensating balances, as credit extension is not guaranteed but is subject to the availability of funds.

	The funded status of our U.S. qualified and nonqualified defined benefit pension plans, our United Kingdom, Ireland, Belgium, and Norway defined benefit pension plans, plus our U.S. other postretirement healthcare and life insurance benefit plans for continuing operations, together with the associated balances and net periodic benefit cost recognized in our consolidated financial statements as of December 31, are shown in the tables below.
	We are required to recognize in our consolidated balance sheets the overfunded and underfunded status of our defined benefit postretirement plans. The overfunded or underfunded status is defined as the difference between the fair value of plan assets and the projected benefit obligation. We are also required to recognize as a component of other comprehensive income the actuarial gains and losses and the prior service costs and credits that arise during the period.

Our U.S. qualified defined benefit pension plan (“U.S. Plan”) holds the majority of our pension plan assets. The expected long-term rate of return on these plan assets was 7.75 percent for the years ended December 31, 2014, 2013 and 2012. In developing the assumption for the long-term rate of return on assets for our U.S. Plan, we take into consideration the technical analysis performed by our outside actuaries, including historical market returns, information on the assumption for long-term real returns by asset class, inflation assumptions and expectations for standard deviation related to these best estimates. We also consider the historical performance of our own plan’s trust, which has earned a compound annual rate of return of approximately 10.3 percent over the last 20 years (which is in excess of comparable market indices for the same period) and other factors. Given an actively managed investment portfolio, the expected annual rates of return by asset class for our portfolio, assuming an estimated inflation rate of approximately 2.2 percent, is between 8.9 percent and 10.6 percent for equities, and between 5.9 percent and 6.8 percent for fixed-income investments, which generates a total expected portfolio return that is in line with our assumption for the rate of return on assets. The target asset allocation for 2014, by asset category, is 75 to 85 percent equity securities, 15 to 25 percent fixed income investments and zero to five percent cash and other short-term investments.
Our U.S. qualified pension plan’s investment strategy consists of a total return investment management approach using a portfolio mix of equities and fixed income investments to maximize the long-term return of plan assets for an appropriate level of risk. The goal of this strategy is to minimize plan expenses by matching asset growth to the plan’s liabilities over the long run. Furthermore, equity investments are weighted towards value equities and diversified across U.S. and non-U.S. stocks. Derivatives and hedging instruments may be used effectively to manage and balance risks associated with the plan’s investments. Investment performance and related risks are measured and monitored on an ongoing basis through annual liability measurements, periodic asset and liability studies, and quarterly investment portfolio reviews.
The following tables present our fair value hierarchy for our major categories of pension plan assets by asset class. See Note 17 for the definition of fair value and the descriptions of Level 1, 2 and 3 in the fair value hierarchy.

-1	As of December 31, 2014 and 2013 we have $88.6 million and $95.8 million, respectively, of investments in certain funds where the net asset value reported by the underlying funds approximates the fair value. These investments are redeemable with the fund at net asset value under the original terms of the partnership agreements and/or subscription agreements and operations of the underlying funds. However, it is possible that these redemption rights may be restricted or eliminated by the funds in the future in accordance with the underlying fund agreements. Due to the nature of the investments held by the funds, changes in market conditions and the economic environment may significantly impact the net asset value of the funds and, consequently, the fair value of the interests in the funds. Furthermore, changes to the liquidity provisions of the funds may significantly impact the fair value of the interest in the funds.
The change in the value of plan assets using significant unobservable inputs (Level 3) for all periods presented was not material.
We made the following contributions to our pension and other postretirement benefit plans:
	Year Ended December 31,

U.S. nonqualified pension plan	10.8			19.8
Non-U.S. plans	4.9			5.5
Other postretirement benefits, net of participant contributions	2.6			2.7
Total	$	68.3		$	68
We expect our voluntary cash contributions to our U.S. qualified pension plan to be $65 million in 2015.
The following table reflects the estimated future benefit payments for our pension and other postretirement benefit plans. These estimates take into consideration expected future service, as appropriate:
Estimated Net Future Benefit Payments (in Millions)
(in Millions)	Pension Benefits	Other Benefits
2015	$73.70	2.6
2016	77.3	2.5

2018	83.4	2.2
2019	86.7	2.1
2020-2024	$467.50	9.3
Assumed health care cost trend rates have an effect on the other postretirement benefit obligations and net periodic other postretirement benefit costs reported for the health care portion of the other postretirement plan. A one-percentage point change in the assumed health care cost trend rates would be immaterial to our net periodic other postretirement benefit costs for the year ended December 31, 2014, and our other postretirement benefit obligation at December 31, 2014.
FMC Corporation Savings and Investment Plan. The FMC Corporation Savings and Investment Plan is a qualified salary-reduction plan under Section 401(k) of the Internal Revenue Code in which substantially all of our U.S. employees may participate by contributing a portion of their compensation. For eligible employees participating in the Plan, except for those employees covered by certain collective bargaining agreements, the Company makes matching contributions of 80 percent of the portion of those contributions up to five percent of the employee’s compensation. Eligible employees participating in the Plan that do not participate in the U.S. qualified pension plan are entitled to receive an employer contribution of five percent of the employee’s eligible compensation. Charges against income for all contributions were $11.4 million in 2014, $11.8 million in 2013, and $10.2 million in 2012.

Share-based Compensation	Share-based Compensation
	Stock Compensation Plans
	We have a share-based compensation plan, which has been approved by the stockholders, for certain employees, officers and directors. This plan is described below.
	FMC Corporation Incentive Compensation and Stock Plan
	The FMC Corporation Incentive Compensation and Stock Plan (the “Plan”) provides for the grant of a variety of cash and equity awards to officers, directors, employees and consultants, including stock options, restricted stock, performance units (including restricted stock units), stock appreciation rights, and multi-year management incentive awards payable partly in cash and partly in common stock. The Compensation and Organization Committee of the Board of Directors (the “Committee”), subject to the provisions of the Plan, approves financial targets, award grants, and the times and conditions for payment of awards to employees. The total number of shares of common stock authorized for issuance under the Plan is 29.0 million of which approximately 6.0 million shares of common stock are available for future grants of share based awards under the Plan as of December 31, 2014. The FMC Corporation Non-Employee Directors’ Compensation Policy, administered by the Nominating and Corporate Governance Committee of the Board of Directors, sets forth the compensation to be paid to the directors, including awards (currently restricted stock units only) to be made to directors under the Plan.
	Stock options granted under the Plan may be incentive or nonqualified stock options. The exercise price for stock options may not be less than the fair market value of the stock at the date of grant. Awards granted under the Plan vest or become exercisable or payable at the time designated by the Committee, which has generally been three years from the date of grant. Incentive and nonqualified options granted under the Plan expire not later than 10 years from the grant date.
	Under the Plan, awards of restricted stock and restricted stock units may be made to selected employees. The awards vest over periods designated by the Committee, which has generally been 3 years, with vesting conditional upon continued employment. Compensation cost is recognized over the vesting periods based on the market value of the stock on the date of the award. Restricted stock units granted to directors under the Plan vest immediately if granted as part of, or in lieu of, the annual retainer (but are subject to forfeiture on a pro rata basis if the director does not serve the full year except under certain circumstances); other restricted stock units granted to directors vest at the Annual Meeting of Shareholders in the calendar year following the May 1 annual grant date.
	At December 31, 2014 and 2013, there were restricted stock units representing an aggregate of 140,656 shares and 142,200 shares of common stock, respectively, credited to the directors’ accounts.
	Stock Compensation
	We recognized the following stock compensation expense:
		Year Ended December 31,
	(in Millions)	2014				2013			2012
	Stock Option Expense, net of taxes of $2.2, $2.4 and $2.7 (1)	$	3.8			$	4.2		$	4.4
	Restricted Stock Expense, net of taxes of $3.3, $3.1 and $3.9 (2)	5.5				5.5			6.4
	Total Stock Compensation Expense, net of taxes of $5.5, $5.5 and $6.6 (3)	$	9.3			$	9.7		$	10.8
	____________________
	-1	We applied an estimated forfeiture rate of four percent per stock option grant in the calculation of the expense.
	-2	We applied an estimated forfeiture rate of two percent of outstanding grants in the calculation of the expense.
	-3	This expense is classified as selling, general and administrative expense in our consolidated statements of income. Total stock compensation expense, net of tax, of $0.5 million, $1.0 million, and $1.4 million for the years ended December 31, 2014, 2013 and 2012, respectively, is included in the Discontinued operations, net of income taxes in the Consolidated Statements of Income.
	We received $8.7 million, $10.7 million and $18.8 million in cash related to stock option exercises for the years ended December 31, 2014, 2013 and 2012, respectively. The shares used for the exercise of stock options occurring during the years ended December 31, 2014, 2013 and 2012 came from treasury shares.
	For tax purposes, share-based compensation expense is deductible in the year of exercise or vesting based on the intrinsic value of the award on the date of exercise or vesting. For financial reporting purposes, share-based compensation expense is based upon grant-date fair value and amortized over the vesting period. Excess tax benefits represent the difference between the share-based compensation expense for financial reporting purposes and the deduction taken for tax purposes. The excess tax benefits for the years ended December 31, 2014, 2013 and 2012 totaled $4.7 million, $7.1 million and $9.7 million, respectively.
	Stock Options
	The grant-date fair values of the stock options we granted in the years ended December 31, 2014, 2013 and 2012 were estimated using the Black-Scholes option valuation model, the key assumptions for which are listed in the table below. The expected volatility assumption is based on the actual historical experience of our common stock. The expected life represents the period of time that options granted are expected to be outstanding. The risk-free interest rate is based on U.S. Treasury securities with terms equal to the expected timing of stock option exercises as of the grant date. The dividend yield assumption reflects anticipated dividends on our common stock.
	Black Scholes valuation assumptions for stock option grants:
		2014		2013		2012
	Expected dividend yield	0.74%		0.91%		0.63%
	Expected volatility	41.96%		42.10%		42.09%
	Expected life (in years)	6.5		6.5		6.5
	Risk-free interest rate	2.01%		1.29%		1.30%
	The weighted-average grant-date fair value of options granted during the years ended December 31, 2014, 2013 and 2012 was $30.01, $23.32 and $19.26 per share, respectively.
	The following summary shows stock option activity for employees under the Plan for the three years ended December 31, 2014:
		Number of Options Granted			Weighted-Average		Weighted-Average			Aggregate Intrinsic
		But Not Exercised			Remaining		Exercise Price Per  Share			Value

	The number of stock options indicated in the above table as being exercisable as of December 31, 2014, had an intrinsic value of $29.2 million, a weighted-average remaining contractual term of 3.9 years, and a weighted-average exercise price of $28.45.
	As of December 31, 2014, we had total remaining unrecognized compensation cost related to unvested stock options of $7.4 million which will be amortized over the weighted-average remaining requisite service period of approximately 1.8 years.
	Restricted Equity Awards
	The grant-date fair value of restricted stock awards and stock units under the Plan is based on the market price per share of our common stock on the date of grant, and the related compensation cost is amortized to expense on a straight-line basis over the vesting period during which the employees perform related services, which is typically three years except for those eligible for retirement prior to the stated vesting period.
	The following table shows our employee restricted award activity for the three years ended December 31, 2014:
	Number of Awards in Thousands	Number of		Weighted-

	-1	Amounts in parentheses indicate charges to the consolidated statements of income.
	-2	Pension and other postretirement benefits amounts include the impact from both continuing and discontinued operations. For detail on the continuing operations components of pension and other postretirement benefits, see Note 13.
	-3	The reclassification of historical cumulative translation adjustments was the result of the divestiture of our FMC Peroxygens business. The loss recognized from this reclassification is considered permanent for tax purposes and therefore no tax has been provided. See Note 9 for more information. In accordance with accounting guidance, this amount was previously factored into the lower of cost or fair value test associated with the 2013 Peroxygens' asset held for sale write-down charges.
	Noncontrolling interest purchase
In 2013 we purchased an additional 6.25 percent ownership interest in a legal entity within our FMC Alkali Chemicals division for $80.0 million from one of two remaining noncontrolling interest holders. In 2014 we purchased the remaining 6.25 percent ownership interest from the last remaining non-controlling interest holder for $95.7 million.
Dividends and Share Repurchases
On January 15, 2015, we paid dividends totaling $20.1 million to our shareholders of record as of December 31, 2014. This amount is included in “Accrued and other liabilities” on the consolidated balance sheets as of December 31, 2014. For the years ended December 31, 2014, 2013 and 2012, we paid $78.1 million, $73.6 million and $47.8 million in dividends, respectively.
We did not repurchase any shares under the publicly announced repurchase program. At December 31, 2014, $250.0 million remained unused under our Board-authorized repurchase program. This repurchase program does not include a specific timetable or price targets and may be suspended or terminated at any time. Shares may be purchased through open market or privately negotiated transactions at the discretion of management based on its evaluation of market conditions and other factors. We also reacquire shares from time to time from employees in connection with the vesting, exercise and forfeiture of awards under our equity compensation plans.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share
	Earnings per common share ("EPS") is computed by dividing net income by the weighted average number of common shares outstanding during the period on a basic and diluted basis.
	Our potentially dilutive securities include potential common shares related to our stock options, restricted stock and restricted stock units. Diluted earnings per share (“Diluted EPS”) considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an antidilutive effect. Diluted EPS excludes the impact of potential common shares related to our stock options in periods in which the option exercise price is greater than the average market price of our common stock for the period. For the years ended December 31, 2014 and 2013 there were 386 thousand and 374 thousand potential common shares excluded from Diluted EPS. For the year ended December 31, 2012 there were no potential common shares excluded from Diluted EPS.
	Our non-vested restricted stock awards contain rights to receive non-forfeitable dividends, and thus, are participating securities requiring the two-class method of computing EPS. The two-class method determines EPS by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of shares of common stock outstanding for the period. In calculating the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period.
	Earnings applicable to common stock and common stock shares used in the calculation of basic and diluted earnings per share are as follows:

Financial Instruments Risk Management And Fair Value Measurements [Abstract]
Financial Instrument, Risk Management and Fair Value Measurements	Financial Instruments, Risk Management and Fair Value Measurements
	Our financial instruments include cash and cash equivalents, trade receivables, other current assets, certain receivables classified as other long-term assets, accounts payable, and amounts included in investments and accruals meeting the definition of financial instruments. The carrying value of these financial instruments approximates their fair value. Our other financial instruments include the following:
	Financial Instrument		Valuation Method
	Foreign exchange forward contracts		Estimated amounts that would be received or paid to terminate the contracts at the reporting date based on current market prices for applicable currencies.
	Commodity forward and option contracts		Estimated amounts that would be received or paid to terminate the contracts at the reporting date based on quoted market prices for applicable commodities.
	Debt		Our estimates and information obtained from independent third parties using market data, such as bid/ask spreads for the last business day of the reporting period.
	The estimated fair value of the financial instruments in the above table have been determined using standard pricing models which take into account the present value of expected future cash flows discounted to the balance sheet date. These standard pricing models utilize inputs derived from, or corroborated by, observable market data such as interest rate yield curves and currency and commodity spot and forward rates. In addition, we test a subset of our valuations against valuations received from the transaction's counterparty to validate the accuracy of our standard pricing models. Accordingly, the estimates presented may not be indicative of the amounts that we would realize in a market exchange at settlement date and do not represent potential gains or losses on these agreements. The estimated fair values of foreign exchange forward contracts and commodity forward and option contracts are included in the tables within this Note. The estimated fair value of debt is $1,773.2 million and $1,895.8 million and the carrying amount is $1,678.6 million and $1,851.9 million as of December 31, 2014 and December 31, 2013, respectively.
	We enter into various financial instruments with off-balance-sheet risk as part of the normal course of business. These off-balance sheet instruments include financial guarantees and contractual commitments to extend financial guarantees under letters of credit, and other assistance to customers (Note 18). Decisions to extend financial guarantees to customers, and the amount of collateral required under these guarantees is based on our evaluation of creditworthiness on a case-by-case basis.
	Use of Derivative Financial Instruments to Manage Risk
	We mitigate certain financial exposures, including currency risk, commodity purchase exposures and interest rate risk through a program of risk management that includes the use of derivative financial instruments. We enter into foreign exchange contracts, including forward and purchased option contracts, to reduce the effects of fluctuating foreign currency exchange rates.
	We formally document all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. This process includes relating derivatives that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. We also assess both at the inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in fair values or cash flows of the hedged item. If we determine that a derivative is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, we discontinue hedge accounting with respect to that derivative prospectively.
	Foreign Currency Exchange Risk Management
	We conduct business in many foreign countries, exposing earnings, cash flows, and our financial position to foreign currency risks. The majority of these risks arise as a result of foreign currency transactions. Our policy is to minimize exposure to adverse changes in currency exchange rates. This is accomplished through a controlled program of risk management that includes the use of foreign currency debt and forward foreign exchange contracts. We also use forward foreign exchange contracts to hedge firm and highly anticipated foreign currency cash flows, with an objective of balancing currency risk to provide adequate protection from significant fluctuations in the currency markets.
	The primary currencies for which we have exchange rate exposure are the U.S. dollar versus the euro, the Chinese yuan, the Brazilian real and the Argentine peso.
	Commodity Price Risk
	We are exposed to risks in energy costs due to fluctuations in energy prices, particularly natural gas. We attempt to mitigate our exposure to increasing energy costs by hedging the cost of future deliveries of natural gas.
	Our Agricultural Solutions segment enters into contracts with certain customers in Brazil whereby we exchange our products for physical delivery of soybeans from the customer. In order to mitigate the price risk associated with these barter contracts, we have entered into offsetting derivatives to hedge our exposure.
	Interest Rate Risk
	We use various strategies to manage our interest rate exposure, including entering into interest rate swap agreements to achieve a targeted mix of fixed and variable-rate debt. In the agreements we exchange, at specified intervals, the difference between fixed and variable-interest amounts calculated on an agreed-upon notional principal amount. As of December 31, 2014 and December 31, 2013, we had no such swap agreements in place.
	Concentration of Credit Risk
	Our counterparties to derivative contracts are primarily major financial institutions. We limit the dollar amount of contracts entered into with any one financial institution and monitor counterparties’ credit ratings. We also enter into master netting agreements with each financial institution, where possible, which helps mitigate the credit risk associated with our financial instruments. While we may be exposed to credit losses due to the nonperformance of counterparties, we consider this risk remote.
	Financial Guarantees and Letter-of-Credit Commitments
	We enter into various financial instruments with off-balance-sheet risk as part of the normal course of business. These off-balance-sheet instruments include financial guarantees and contractual commitments to extend financial guarantees under letters of credit and other assistance to customers (Notes 1 and 19). Decisions to extend financial guarantees to customers, and the amount of collateral required under these guarantees, is based on our evaluation of creditworthiness on a case-by-case basis.
	Accounting for Derivative Instruments and Hedging Activities
	Cash Flow Hedges
	We recognize all derivatives on the balance sheet at fair value. On the date the derivative instrument is entered into, we generally designate the derivative as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge). We record in AOCI changes in the fair value of derivatives that are designated as and meet all the required criteria for, a cash flow hedge. We then reclassify these amounts into earnings as the underlying hedged item affects earnings. In contrast we immediately record in earnings changes in the fair value of derivatives that are not designated as cash flow hedges.
	As of December 31, 2014, we had open foreign currency forward contracts in AOCI in a net after-tax loss position of $0.6 million designated as cash flow hedges of underlying forecasted sales and purchases. Current open contracts hedge forecasted transactions until December 31, 2015. At December 31, 2014, we had open forward contracts with various expiration dates to buy, sell or exchange foreign currencies with a U.S. dollar equivalent of approximately $567.1 million.
	As of December 31, 2014, we had current open commodity contracts in AOCI in a net after-tax loss position of $4.6 million designated as cash flow hedges of underlying forecasted purchases, primarily related to natural gas. Current open commodity contracts hedge forecasted transactions until December 31, 2016. At December 31, 2014, we had 5.5 million mmBTUs (millions of British Thermal Units) in aggregate notional volume of outstanding natural gas commodity forward contracts to hedge forecasted purchases.
	Of the $5.2 million of net after-tax losses, representing both open foreign currency exchange contracts and open commodity contracts, substantially all of the $5.2 million of these losses would be realized in earnings during the twelve months ending December 31, 2015, if spot rates in the future are consistent with forward rates as of December 31, 2014. The actual effect on earnings will be dependent on the actual spot rates when the forecasted transactions occur. We recognize derivative gains and losses in the “Costs of sales and services” line in the consolidated statements of income.
	Derivatives Not Designated As Hedging Instruments
	We hold certain forward contracts that have not been designated as cash flow hedging instruments for accounting purposes. Contracts used to hedge the exposure to foreign currency fluctuations associated with certain monetary assets and liabilities are not designated as cash flow hedging instruments, and changes in the fair value of these items are recorded in earnings. We periodically hold soybean barter contracts which qualify as derivatives and we have entered into offsetting commodity contracts to hedge our exposure. Both the change in fair value of the soybean barter contracts and the offsetting commodity contracts are recorded in earnings.
	We had open forward contracts not designated as cash flow hedging instruments for accounting purposes with various expiration dates to buy, sell or exchange foreign currencies with a U.S. dollar equivalent of approximately $6.1 billion at December 31, 2014, which included approximately $5.2 billion associated with the derivative contracts to hedge the purchase of Cheminova.

Fair-Value Measurements
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are defined as buyers or sellers in the principle or most advantageous market for the asset or liability that are independent of the reporting entity, knowledgeable and able and willing to transact for the asset or liability.
Fair-Value Hierarchy
We have categorized our assets and liabilities that are recorded at fair value, based on the priority of the inputs to the valuation technique, into a three-level fair-value hierarchy. The fair-value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the assets and liabilities fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair-value measurement of the instrument.

The following tables present our fair-value hierarchy for those assets and liabilities measured at fair-value on a recurring basis in our consolidated balance sheets.

	Guarantees
	We continue to monitor the conditions that are subject to guarantees and indemnifications to identify whether a liability must be recognized in our financial statements.
	The following table provides the estimated undiscounted amount of potential future payments for each major group of guarantees at December 31, 2014. These guarantees arise during the ordinary course of business from relationships with customers and nonconsolidated affiliates. Non-performance by the guaranteed party triggers the obligation requiring us to make payments to the beneficiary of the guarantee. Based on our experience these types of guarantees have not had a material effect on our consolidated financial position or on our liquidity. Our expectation is that future payment or performance related to the non-performance of others is considered unlikely.
	(in Millions)
	Guarantees:
	Guarantees of vendor financing (1)	$	50.2
	Debt guarantees (2)	68.2
	Total	$	118.4
	____________________
	-1	Represents guarantees to financial institutions on behalf of certain FMC Agricultural Solutions customers for their seasonal borrowing. This amount is recorded on the condensed consolidated balance sheets as “Guarantees of vendor financing.”
	-2	These guarantees represent support provided to third-party banks for credit extended to various FMC Agricultural Solutions customers and nonconsolidated affiliates. The liability for the guarantees is recorded at an amount that approximates fair-value (i.e. representing the stand-ready obligation) based on our historical collection experience and a current assessment of credit exposure. We believe the fair-value of these guarantees is immaterial. The majority of these guarantees have an expiration date of less than one year.
	Excluded from the chart above, in connection with our property and asset sales and divestitures, we have agreed to indemnify the buyers for certain liabilities, including environmental contamination and taxes that occurred prior to the date of sale or provided guarantees to third parties relating to certain contracts assumed by the buyer. Our indemnification or guarantee obligations with respect to these liabilities may be indefinite as to duration and may or may not be subject to a deductible, minimum claim amount or cap. As such, it is not possible for us to predict the likelihood that a claim will be made or to make a reasonable estimate of the maximum potential loss or range of loss. If triggered, we may be able to recover some of the indemnity payments from third parties. We have not recorded any specific liabilities for these guarantees.
	Commitments
	Leases
	We lease office space, plants and facilities, and various types of manufacturing, data processing and transportation equipment. Leases of real estate generally provide for our payment of property taxes, insurance and repairs. Our capital leases primarily relate to our two research and technology centers in the U.S. and China. Our capital lease asset balances (net of accumulated amortization of $1.4 million and $0.9 million), which are classified as buildings within our property, plant and equipment on our consolidated balance sheets, were $28.7 million and $29.3 million as of December 31, 2014 and 2013, respectively. Amortization of capital lease assets is included within depreciation expense. See Note 20 within these consolidated financial statements for obligations associated with our capital leases.

Since the majority of our minimum obligations under these contracts are over the life of the contract as opposed to a year-by-year basis, we are unable to determine the periods in which these obligations could be payable under these contracts. However, we intend to fulfill the obligations associated with these contracts through our purchases associated with the normal course of business.
	Contingencies
	Competition / antitrust litigation related to the discontinued FMC Peroxygens segment. We are subject to actions brought by private plaintiffs relating to alleged violations of European and Canadian competition and antitrust laws, as further described below.
	European competition action. Multiple European purchasers of hydrogen peroxide who claim to have been harmed as a result of alleged violations of European competition law by hydrogen peroxide producers assigned their legal claims to a single entity formed by a law firm. The single entity then filed a lawsuit in Germany in March 2009 against European producers, including our wholly-owned Spanish subsidiary, Foret. Initial defense briefs were filed in April 2010, and an initial hearing was held during the first quarter of 2011, at which time case management issues were discussed. At a subsequent hearing in October 2011, the Court indicated that it was considering seeking guidance from the European Court of Justice (“ECJ”) as to whether the German courts have jurisdiction over these claims. After submission of written comments on this issue by the parties, on March 1, 2012, the judge announced that she would refer the jurisdictional issues to the ECJ, which she did on April 29, 2013. The ECJ had not yet issued a ruling in the reference proceeding. Since the case is in the preliminary stages and is based on a novel procedure - namely the attempt to create a cross-border “class action” which is not a recognized proceeding under EU or German law - we are unable to develop a reasonable estimate of our potential exposure of loss at this time. We intend to vigorously defend this matter.
	Canadian antitrust actions. In 2005, after public disclosures of the U.S. federal grand jury investigation into the hydrogen peroxide industry (which resulted in no charges brought against us) and the filing of various class actions in U.S. federal and state courts, which have all been settled, putative class actions against us and five other major hydrogen peroxide producers were filed in provincial courts in Ontario, Quebec and British Columbia under the laws of Canada. The other five defendants have settled these claims for a total of approximately $20.6 million. On September 28, 2009, the Ontario Superior Court of Justice certified a class of direct and indirect purchasers of hydrogen peroxide from 1994 to 2005. Our motion for leave to appeal the class certification decision was denied in June 2010. The case was largely dormant while the Canadian Supreme Court considered, in different litigation, whether indirect purchasers may recover overcharges in antitrust actions. In October 2013 the Court ruled that such recovery is permissible. Despite this ruling, the plaintiffs have now moved to dismiss certain downstream purchasers from the case and to reduce the class period to November 1, 1998 through December 31, 2003 - thereby eliminating six of the eleven years of the originally certified class period. Since the proceedings are in the preliminary stages with respect to the merits, we are unable to develop a reasonable estimate of our potential exposure of loss at this time. We intend to vigorously defend these matters.
	Asbestos claims. Like hundreds of other industrial companies, we have been named as one of many defendants in asbestos-related personal injury litigation. Most of these cases allege personal injury or death resulting from exposure to asbestos in premises of FMC or to asbestos-containing components installed in machinery or equipment manufactured or sold by businesses classified as discontinued operations. We intend to continue managing these cases in accordance with our historical experience. We have established a reserve for this litigation within our discontinued operations and are unable to develop a reasonable estimate of any exposure of a loss in excess of the established reserve. Our experience has been that the overall trends in terms of the rate of filing of asbestos-related claims with respect to all potential defendants has changed over time, and that filing rates as to us in particular have varied significantly over the last several years. We are a peripheral defendant - that is, we have never manufactured asbestos or asbestos-containing components. As a result, claim filing rates against us have yet to form a predictable pattern, and we are unable to project a reasonably accurate future filing rate and thus, we are presently unable to reasonably estimate our asbestos liability with respect to claims that may be filed in the future.
	Other contingent liabilities. In addition to the matters disclosed above, we have certain other contingent liabilities arising from litigation, claims, products we have sold, guarantees or warranties we have made, contracts we have entered into, indemnities we have provided, and other commitments incident to the ordinary course of business. Some of these contingencies are known - for example pending product liability litigation or claims - but are so preliminary that the merits cannot be determined, or if more advanced, are not deemed material based on current knowledge; and some are unknown - for example, claims with respect to which we have no notice or claims which may arise in the future, resulting from products we have sold, guarantees or warranties we have made, or indemnities we have provided. Therefore, we are unable to develop a reasonable estimate of our potential exposure of loss for these contingencies, either individually or in the aggregate, at this time. Based on information currently available and established reserves, we have no reason to believe that the ultimate resolution of our known contingencies, including the matters described in this Note, will have a material adverse effect on our consolidated financial position, liquidity or results of operations. However, there can be no assurance that the outcome of these contingencies will be favorable, and adverse results in certain of these contingencies could have a material adverse effect on our consolidated financial position, results of operations in any one reporting period, or liquidity.

	____________________
	-1	See Note 7 for details of restructuring and other charges (income). Amounts for the years ended 2014, 2013 and 2012 relate to FMC Agricultural Solutions of $(4.5) million, $32.6 million and $8.5 million; FMC Health and Nutrition of $14.1 million, $1.0 million and $0.7 million; FMC Minerals of $0.1 million, $6.4 million and $13.0 million; and Corporate of $46.8 million, $7.9 million and $5.3 million, respectively.
	-2	Our non-operating pension and postretirement costs are defined as those costs related to interest, expected return on plan assets, amortized actuarial gains and losses and the impacts of any plan curtailments or settlements. These costs are primarily related to changes in pension plan assets and liabilities which are tied to financial market performance and we consider these costs to be outside our operational performance. We exclude these non-operating pension and postretirement costs from our segments as we believe that removing them provides a better understanding of the underlying profitability of our businesses, provides increased transparency and clarity in the performance of our retirement plans and enhances period-over-period comparability. We continue to include the service cost and amortization of prior service cost in our operating segments noted above. We believe these elements reflect the current year operating costs to our businesses for the employment benefits provided to active employees. These expenses are included as a component of the line item "Selling, general and administrative expenses" on our consolidated statements of income.
	-3	Charges are associated with the previously planned separation of our FMC Corporation into two independent public companies. On September 8, 2014, we announced that we would no longer proceed with the planned separation of FMC into two distinct public entities. At that time we announced the acquisition of Cheminova; see Note 3 within these consolidated financial statements for more information. These charges are included within "Business separation costs" on our consolidated income statement. These costs were primarily related to professional fees associated with separation activities within the finance and legal functions through September 8, 2014.
	-4	Charges related to the expensing of the inventory fair value step-up resulting from the application of purchase accounting, legal and professional fees and gains or losses on hedging purchase price associated with the planned or completed acquisitions and costs incurred associated with the divestiture of our FMC Alkali Chemicals division.

At December 31, 2014 and 2013, $42.2 million and $35.0 million of outstanding receivables due from the Argentina government, which primarily represent export tax and valued added tax receivables, were denominated in U.S. dollars. As with all outstanding receivable balances we continually review recoverability by analyzing historical experience, current collection trends and regional business and political factors among other factors. We have further analyzed the recoverability of our outstanding receivables from the Argentina government in light of the current economic and political environment within Argentina, including the recent credit downgrades of local and federal governments and the July 31, 2014 default by the Argentina government on some of its debt obligations. Based on our analysis of the impact of economic conditions in Argentina on our receivables, at this time, we believe the outstanding receivables to be recoverable.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event
	In September 2014, we announced our decision to pursue the sale of our FMC Alkali Chemicals division (“ACD”). On February 3, 2015, we signed a definitive agreement to sell ACD to a wholly owned subsidiary of Tronox Limited for $1.64 billion. We expect the sale to be completed in early 2015 subject to customary regulatory approvals and closing conditions. The proceeds from the sale will be used to fund the acquisition of Cheminova.
	We have concluded, as a result of the signing of the definitive agreement, that ACD has met the criteria to be an asset held for sale and therefore will be presented as a discontinued operation in accordance with GAAP in future reporting periods. In accordance with GAAP, the reclassification of ACD from a continuing operation to a discontinued operation occurs in the period for which the discontinued operation criteria has been met. Therefore as of December 31, 2014, ACD is accounted for as a continuing operation.
	Beginning with the first quarter 2015 reporting on Form 10-Q, the results of operations of ACD will be reclassified to reflect the business as a discontinued operation for all periods presented and the assets and liabilities of the business will be reclassified as held for sale. Our FMC Minerals segment, which previously included our FMC Alkali Chemicals and FMC Lithium divisions, will be renamed FMC Lithium.
	The carrying amounts of the major classes of assets and liabilities related to ACD were as follows:
	(in Millions)	As of
	Assets	31-Dec-14

Principal Accounting Policies and Related Financial Information (Policies)	12 Months Ended
	Dec. 31, 2014
Principal Accounting Policies and Related Financial Information [Abstract]
Basis of consolidation and basis of presentation	Basis of consolidation and basis of presentation. The accompanying consolidated financial statements of FMC Corporation and its subsidiaries were prepared in accordance with accounting principles generally accepted in the United States of America. Our consolidated financial statements include the accounts of FMC and all entities that we directly or indirectly control. All significant intercompany accounts and transactions are eliminated in consolidation.
Estimates and assumptions	Estimates and assumptions. In preparing the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results are likely to differ from those estimates, but we do not believe such differences will materially affect our financial position, results of operations or cash flows.
Cash equivalents	Cash equivalents. We consider investments in all liquid debt instruments with original maturities of 3 months or less to be cash equivalents.
Trade receivables, net of allowance	Trade receivables, net of allowance. Trade receivables consist of amounts owed to us from customer sales and are recorded when revenue is recognized. The allowance for trade receivables represents our best estimate of the probable losses associated with potential customer defaults. In developing our allowance for trade receivables, we utilize a two stage process which includes calculating a general formula to develop an allowance to appropriately address the uncertainty surrounding collection risk of our entire portfolio and specific allowances for customers where the risk of collection has been reasonably identified either due to liquidity constraints or disputes over contractual terms and conditions.
	Our method of calculating the general formula consists of estimating the recoverability of trade receivables based on historical experience, current collection trends, and external business factors such as economic factors, including regional bankruptcy rates, and political factors. Our analysis of trade receivable collection risk is performed quarterly, and the allowance is adjusted accordingly. The allowance for trade receivable is $37.6 million and $30.2 million as of December 31, 2014 and 2013, respectively. The provision to the allowance for trade receivables charged against operations was $9.4 million, $5.7 million and $8.8 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Investments	Investments. Investments in companies in which our ownership interest is 50 percent or less and in which we exercise significant influence over operating and financial policies are accounted for using the equity method. Under the equity method, original investments are recorded at cost and adjusted by our share of undistributed earnings and losses of these investments. Majority owned investments in which our control is restricted are also accounted for using the equity method. All other investments are carried at their fair values or at cost, as appropriate. We are party to several joint venture investments throughout the world, which individually and in the aggregate are not significant to our financial results.
Inventories	Inventories. Inventories are stated at the lower of cost or market value. Inventory costs include those costs directly attributable to products before sale, including all manufacturing overhead but excluding distribution costs. All domestic inventories, excluding materials and supplies, are determined on a last-in, first-out (“LIFO”) basis and our remaining inventories are recorded on a first-in, first-out (“FIFO”) basis. See Note 5.
Property, plant and equipment	Property, plant and equipment. We record property, plant and equipment, including capitalized interest, at cost. Depreciation is provided principally on the straight-line basis over the estimated useful lives of the assets (land improvements—20 years, buildings—20 to 40 years, and machinery and equipment—three to 18 years). Gains and losses are reflected in income upon sale or retirement of assets. Expenditures that extend the useful lives of property, plant and equipment or increase productivity are capitalized. Ordinary repairs and maintenance are expensed as incurred through operating expense.
Capitalized interest	Capitalized interest. We capitalized interest costs of $10.2 million in 2014, $5.7 million in 2013 and $7.2 million in 2012. These costs were associated with the construction of certain long-lived assets and have been capitalized as part of the cost of those assets. We amortize capitalized interest over the assets’ estimated useful lives.
Impairments of long-lived assets	Impairments of long-lived assets. We review the recovery of the net book value of long-lived assets whenever events and circumstances indicate that the net book value of an asset may not be recoverable from the estimated undiscounted future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the net book value, we recognize an impairment loss equal to an amount by which the net book value exceeds the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.
Asset retirement obligation	Asset retirement obligations. We record asset retirement obligations at fair value at the time the liability is incurred if we can reasonably estimate the settlement date. The associated asset retirement obligations (“AROs”) are capitalized as part of the carrying amount of related long-lived assets. In future periods, the liability is accreted to its present value and the capitalized cost is depreciated over the useful life of the related asset. We also adjust the liability for changes resulting from the passage of time and/or revisions to the timing or the amount of the original estimate. Upon retirement of the long-lived asset, we either settle the obligation for its recorded amount or incur a gain or loss. See Note 8 for further discussion on our AROs.
Restructuring and other charges	Restructuring and other charges. We continually perform strategic reviews and assess the return on our businesses. This sometimes results in a plan to restructure the operations of a business. We record an accrual for severance and other exit costs under the provisions of the relevant accounting guidance.
	Additionally, as part of these restructuring plans, write-downs of long-lived assets may occur. Two types of assets are impacted: assets to be disposed of by sale and assets to be abandoned. Assets to be disposed of by sale are measured at the lower of carrying amount or estimated net proceeds from the sale. Assets to be abandoned with no remaining future service potential are written down to amounts expected to be recovered. The useful life of assets to be abandoned that have a remaining future service potential are adjusted and depreciation is recorded over the adjusted useful life.
Capitalized software	Capitalized software. We capitalize the costs of internal use software in accordance with accounting literature which generally requires the capitalization of certain costs incurred to develop or obtain internal use software. We assess the recoverability of capitalized software costs on an ongoing basis and record write-downs to fair value as necessary. We amortize capitalized software costs over expected useful lives ranging from three to 10 years. See Note 20 for the unamortized computer software balances.
Goodwill and intangible assets	Goodwill and intangible assets. Goodwill and other indefinite life intangible assets (“intangibles”) are not subject to amortization. Instead, they are subject to at least an annual assessment for impairment by applying a fair value-based test.
	We test goodwill and indefinite life intangibles for impairment annually using the criteria prescribed by U.S. GAAP accounting guidance for goodwill and other intangible assets. We did not record any goodwill or indefinite life intangible impairments to continuing operations in 2014, 2013 and 2012. Based upon our annual impairment assessment, conducted in 2014, we believe that the fair value of our reporting units with goodwill substantially exceeds their carrying value.
	Finite-lived intangible assets consist primarily of patents, access rights, customer relationships, brands, registration rights, industry licenses, developed formulations and other intangibles and are being amortized over periods of five to 25 years. See Note 4 for additional information on goodwill and intangible assets.
Revenue recognition	Revenue recognition. We recognize revenue when the earnings process is complete, which is generally upon transfer of title. This transfer typically occurs either upon shipment to the customer or upon receipt by the customer. In all cases, we apply the following criteria in recognizing revenue: persuasive evidence of an arrangement exists, delivery has occurred, the selling price is fixed or determinable and collection is reasonably assured. Rebates due to customers are accrued as a reduction of revenue in the same period that the related sales are recorded based on the contract terms.
	We periodically enter into prepayment arrangements with customers, primarily in our FMC Agricultural Solutions segment, and receive advance payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue and classified as “Advance payments from customers” on the consolidated balance sheet. Revenue associated with advance payments is recognized as shipments are made and title, ownership and risk of loss pass to the customer.
	We record amounts billed for shipping and handling fees as revenue. Costs incurred for shipping and handling are recorded as costs of sales and services. Amounts billed for sales and use taxes, value-added taxes, and certain excise and other specific transactional taxes imposed on revenue-producing transactions are presented on a net basis and excluded from sales in the consolidated income statements. We record a liability until remitted to the respective taxing authority.
Research and Development	Research and Development. Research and development costs are expensed as incurred. In-process research and development acquired as part of asset acquisitions, which include license and development agreements, are expensed as incurred and included as a component of “Restructuring and other charges (income)”.
Income and other taxes	Income and other taxes. We provide current income taxes on income reported for financial statement purposes adjusted for transactions that do not enter into the computation of income taxes payable and recognize deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. We do not provide income taxes on the equity in undistributed earnings of consolidated foreign subsidiaries as it is our intention that such earnings will remain invested in those companies.
Foreign currency	Foreign currency. We translate the assets and liabilities of our foreign operations at exchange rates in effect at the balance sheet date. For foreign operations for which the functional currency is not the U.S. dollar we record translation gains and losses as a component of accumulated other comprehensive income in equity. The foreign operations' income statements are translated at the monthly exchange rates for the period.
	We record remeasurement gain and losses on monetary assets and liabilities, such as accounts receivables and payables, which are not in the functional currency of the operation. These remeasurement gains and losses are recorded in the income statement as they occur. We generally enter into foreign currency contracts to mitigate the financial risk associated with these transactions.  See “Derivative financial instruments” below and Note 17.
Derivative financial instruments	Derivative financial instruments. We mitigate certain financial exposures, including currency risk, interest rate risk and commodity price exposures, through a controlled program of risk management that includes the use of derivative financial instruments. We enter into foreign exchange contracts, including forward and purchased option contracts, to reduce the effects of fluctuating foreign currency exchange rates.
	We recognize all derivatives on the balance sheet at fair value. On the date the derivative instrument is entered into, we generally designate the derivative as either a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge) or a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge). We record in accumulated other comprehensive income or loss changes in the fair value of derivatives that are designated as, and meet all the required criteria for, a cash flow hedge. We then reclassify these amounts into earnings as the underlying hedged item affects earnings. We record immediately in earnings changes in the fair value of derivatives that are not designated as cash flow hedges.
	We formally document all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. This process includes relating derivatives that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. We also formally assess, both at the inception of the hedge and throughout its term, whether each derivative is highly effective in offsetting changes in fair value or cash flows of the hedged item. If we determine that a derivative is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, we discontinue hedge accounting with respect to that derivative prospectively.
Treasury stock	Treasury stock. We record shares of common stock repurchased at cost as treasury stock, resulting in a reduction of stockholders’ equity in the Consolidated Balance Sheets. When the treasury shares are contributed under our employee benefit plans or issued for option exercises, we use a first-in, first-out (“FIFO”) method for determining cost. The difference between the cost of the shares and the market price at the time of contribution to an employee benefit plan is added to or deducted from the related capital in excess of par value of common stock.
Segment information	Segment information. We determined our reportable segments based on our strategic business units, the commonalities among the products and services within each segment and the manner in which we review and evaluate operating performance.
	We have identified FMC Agricultural Solutions, FMC Health and Nutrition and FMC Minerals as our reportable segments. Segment disclosures are included in Note 19. Segment operating profit is defined as segment revenue less segment operating expenses (segment operating expenses consist of costs of sales and services, selling, general and administrative expenses and research and development expenses). We have excluded the following items from segment operating profit: corporate staff expense, interest income and expense associated with corporate debt facilities and investments, income taxes, gains (or losses) on divestitures of businesses, restructuring and other charges (income), investment gains and losses, loss on extinguishment of debt, asset impairments, LIFO inventory adjustments, acquisition related costs, non-operating pension and postretirement charges, and other income and expense items. Information about how restructuring and other charges (income) relate to our businesses at the segment level is discussed in Note 7.
	Segment assets and liabilities are those assets and liabilities that are recorded and reported by segment operations. Segment operating capital employed represents segment assets less segment liabilities. Segment assets exclude corporate and other assets, which are principally cash equivalents, the LIFO reserve on inventory, deferred income taxes, eliminations of intercompany receivables and property and equipment not attributable to a specific segment, such as capitalized interest. Segment liabilities exclude substantially all debt, income taxes, pension and other postretirement benefit liabilities, environmental reserves and related recoveries, restructuring reserves, fair value of currency contracts, intercompany eliminations, and reserves for discontinued operations.
	Geographic segment revenue is based on the location of our customers. Geographic segment long-lived assets include investments, net property, plant and equipment, and other non-current assets. Geographic segment data is included in Note 19.
Stock compensation plans	Stock compensation plans. We recognize compensation expense in the financial statements for all share options and other equity-based arrangements. Share-based compensation cost is measured at the date of grant, based on the fair value of the award, and is recognized over the employee’s requisite service period. See Note 14 for further discussion on our share-based compensation.
Environmental obligations	Environmental obligations. We provide for environmental-related obligations when they are probable and amounts can be reasonably estimated. Where the available information is sufficient to estimate the amount of liability, that estimate has been used. Where the information is only sufficient to establish a range of probable liability and no point within the range is more likely than any other, the lower end of the range has been used.
	Estimated obligations to remediate sites that involve oversight by the United States Environmental Protection Agency (“EPA”), or similar government agencies, are generally accrued no later than when a Record of Decision (“ROD”), or equivalent, is issued, or upon completion of a Remedial Investigation/Feasibility Study (“RI/FS”), or equivalent, that is submitted by us and the appropriate government agency or agencies. Estimates are reviewed quarterly and, if necessary, adjusted as additional information becomes available. The estimates can change substantially as additional information becomes available regarding the nature or extent of site contamination, required remediation methods, and other actions by or against governmental agencies or private parties.
	Our environmental liabilities for continuing and discontinued operations are principally for costs associated with the remediation and/or study of sites at which we are alleged to have released hazardous substances into the environment. Such costs principally include, among other items, RI/FS, site remediation, costs of operation and maintenance of the remediation plan, management costs, fees to outside law firms and consultants for work related to the environmental effort, and future monitoring costs. Estimated site liabilities are determined based upon existing remediation laws and technologies, specific site consultants’ engineering studies or by extrapolating experience with environmental issues at comparable sites.
	Included in our environmental liabilities are costs for the operation, maintenance and monitoring of site remediation plans ("OM&M"). Such reserves are based on our best estimates for these OM&M plans. Over time we may incur OM&M costs in excess of these reserves. However, we are unable to reasonably estimate an amount in excess of our recorded reserves because we cannot reasonably estimate the period for which such OM&M plans will need to be in place or the future annual cost of such remediation, as conditions at these environmental sites change over time. Such additional OM&M costs could be significant in total but would be incurred over an extended period of years.
	Included in the environmental reserve balance, other assets balance and disclosure of reasonably possible loss contingencies are amounts from third party insurance policies which we believe are probable of recovery.
	Provisions for environmental costs are reflected in income, net of probable and estimable recoveries from named Potentially Responsible Parties (“PRPs”) or other third parties. Such provisions incorporate inflation and are not discounted to their present values.
	In calculating and evaluating the adequacy of our environmental reserves, we have taken into account the joint and several liability imposed by Comprehensive Environmental Remediation, Compensation and Liability Act (“CERCLA”) and the analogous state laws on all PRPs and have considered the identity and financial condition of the other PRPs at each site to the extent possible. We have also considered the identity and financial condition of other third parties from whom recovery is anticipated, as well as the status of our claims against such parties. Although we are unable to forecast the ultimate contributions of PRPs and other third parties with absolute certainty, the degree of uncertainty with respect to each party is taken into account when determining the environmental reserve on a site-by-site basis. Our liability includes our best estimate of the costs expected to be paid before the consideration of any potential recoveries from third parties. We believe that any recorded recoveries related to PRPs are realizable in all material respects. Recoveries are recorded as either an offset in “Environmental liabilities, continuing and discontinued” or as “Other assets” in our consolidated balance sheets in accordance with U.S. accounting literature.
Pension and other postretirement benefits	Pension and other postretirement benefits. We provide qualified and nonqualified defined benefit and defined contribution pension plans, as well as postretirement health care and life insurance benefit plans to our employees and retirees. The costs (or benefits) and obligations related to these benefits reflect key assumptions related to general economic conditions, including interest (discount) rates, healthcare cost trend rates, expected rates of return on plan assets and the rates of compensation increase for employees. The costs (or benefits) and obligations for these benefit programs are also affected by other assumptions, such as average retirement age, mortality, employee turnover, and plan participation. To the extent our plans’ actual experience, as influenced by changing economic and financial market conditions or by changes to our own plans’ demographics, differs from these assumptions, the costs and obligations for providing these benefits, as well as the plans’ funding requirements, could increase or decrease. When actual results differ from our assumptions, the difference is typically recognized over future periods. In addition, the unrealized gains and losses related to our pension and postretirement benefit obligations may also affect periodic benefit costs (or benefits) in future periods. See Note 13 for additional information relating to pension and other postretirement benefits.
Reclassifications	Reclassifications. Certain prior year amounts have been reclassified to conform with current year's presentation.
New accounting pronouncements	New Accounting guidance and regulatory items
	In February 2015, the Financial Accounting Standards Board ("FASB") issued ASU 2015-02, Consolidation: Amendments to the Consolidation Analysis. This new standard changes the consolidation evaluation for entities that are required to evaluate whether they should consolidate certain legal entities. We are required to adopt this standard in the first quarter of 2016. Early adoption is permitted. The standard permits the use of a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption, or a reporting entity may also apply the amendments retrospectively. We are evaluating the effect that ASU 2015-02 will have on our consolidated financial statements. We have not yet completed the assessment to determine the effect of the standard on our ongoing financial reporting.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This new guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. We are required to adopt this standard on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
	In April 2014, the FASB issued its updated guidance on the financial reporting of discontinued operations. This new standard changes the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Additionally, expanded disclosures about discontinued operations will be required to provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This guidance impacts disclosures within an entity's financial statements and notes to the financial statements. We are required to adopt this guidance prospectively in the first quarter of 2015. The updated guidance will not impact existing conclusions with respect to discontinued operations classification.

	-1	As of December 31, 2014 and 2013 we have $88.6 million and $95.8 million, respectively, of investments in certain funds where the net asset value reported by the underlying funds approximates the fair value. These investments are redeemable with the fund at net asset value under the original terms of the partnership agreements and/or subscription agreements and operations of the underlying funds. However, it is possible that these redemption rights may be restricted or eliminated by the funds in the future in accordance with the underlying fund agreements. Due to the nature of the investments held by the funds, changes in market conditions and the economic environment may significantly impact the net asset value of the funds and, consequently, the fair value of the interests in the funds. Furthermore, changes to the liquidity provisions of the funds may significantly impact the fair value of the interest in the funds.

Commitments Guarantees and Contingent Liabilities [Abstract]
Schedule of Estimated Undiscounted Potential Future Payments for Guarantees	The following table provides the estimated undiscounted amount of potential future payments for each major group of guarantees at December 31, 2014. These guarantees arise during the ordinary course of business from relationships with customers and nonconsolidated affiliates. Non-performance by the guaranteed party triggers the obligation requiring us to make payments to the beneficiary of the guarantee. Based on our experience these types of guarantees have not had a material effect on our consolidated financial position or on our liquidity. Our expectation is that future payment or performance related to the non-performance of others is considered unlikely.
	(in Millions)
	Guarantees:
	Guarantees of vendor financing (1)	$	50.2
	Debt guarantees (2)	68.2
	Total	$	118.4
	____________________
	-1	Represents guarantees to financial institutions on behalf of certain FMC Agricultural Solutions customers for their seasonal borrowing. This amount is recorded on the condensed consolidated balance sheets as “Guarantees of vendor financing.”
	-2	These guarantees represent support provided to third-party banks for credit extended to various FMC Agricultural Solutions customers and nonconsolidated affiliates. The liability for the guarantees is recorded at an amount that approximates fair-value (i.e. representing the stand-ready obligation) based on our historical collection experience and a current assessment of credit exposure. We believe the fair-value of these guarantees is immaterial. The majority of these guarantees have an expiration date of less than one year.

	____________________
	-1	See Note 7 for details of restructuring and other charges (income). Amounts for the years ended 2014, 2013 and 2012 relate to FMC Agricultural Solutions of $(4.5) million, $32.6 million and $8.5 million; FMC Health and Nutrition of $14.1 million, $1.0 million and $0.7 million; FMC Minerals of $0.1 million, $6.4 million and $13.0 million; and Corporate of $46.8 million, $7.9 million and $5.3 million, respectively.
	-2	Our non-operating pension and postretirement costs are defined as those costs related to interest, expected return on plan assets, amortized actuarial gains and losses and the impacts of any plan curtailments or settlements. These costs are primarily related to changes in pension plan assets and liabilities which are tied to financial market performance and we consider these costs to be outside our operational performance. We exclude these non-operating pension and postretirement costs from our segments as we believe that removing them provides a better understanding of the underlying profitability of our businesses, provides increased transparency and clarity in the performance of our retirement plans and enhances period-over-period comparability. We continue to include the service cost and amortization of prior service cost in our operating segments noted above. We believe these elements reflect the current year operating costs to our businesses for the employment benefits provided to active employees. These expenses are included as a component of the line item "Selling, general and administrative expenses" on our consolidated statements of income.
	-3	Charges are associated with the previously planned separation of our FMC Corporation into two independent public companies. On September 8, 2014, we announced that we would no longer proceed with the planned separation of FMC into two distinct public entities. At that time we announced the acquisition of Cheminova; see Note 3 within these consolidated financial statements for more information. These charges are included within "Business separation costs" on our consolidated income statement. These costs were primarily related to professional fees associated with separation activities within the finance and legal functions through September 8, 2014.
	-4	Charges related to the expensing of the inventory fair value step-up resulting from the application of purchase accounting, legal and professional fees and gains or losses on hedging purchase price associated with the planned or completed acquisitions and costs incurred associated with the divestiture of our FMC Alkali Chemicals division.

	-1	We have various subsidiaries that conduct business within Argentina, primarily in our FMC Agricultural Solutions and FMC Minerals segments. At December 31, 2014 and 2013, $42.2 million and $35.0 million of outstanding receivables due from the Argentina government, which primarily represent export tax and valued added tax receivables, were denominated in U.S. dollars. As with all outstanding receivable balances we continually review recoverability by analyzing historical experience, current collection trends and regional business and political factors among other factors. We have further analyzed the recoverability of our outstanding receivables from the Argentina government in light of the current economic and political environment within Argentina, including the recent credit downgrades of local and federal governments and the July 31, 2014 default by the Argentina government on some of its debt obligations. Based on our analysis of the impact of economic conditions in Argentina on our receivables, at this time, we believe the outstanding receivables to be recoverable.

[1]	In 2014, the Society of Actuaries released new mortality tables and a mortality improvement scale for measurement of retirement program obligations. The adoption of these new tables is included in the measurement of the December 31, 2014 U.S. defined benefit and post retirement obligations and resulted in an actuarial loss of approximately $95 million.
[2]	Included in “Other assets” on the consolidated balance sheets.
[3]	Recorded as "Accrued pension and other postretirement benefits, current and long-term" on the consolidated balance sheets.
[4]	As of December 31, 2014 and 2013 we have $88.6 million and $95.8 million, respectively, of investments in certain funds where the net asset value reported by the underlying funds approximates the fair value. These investments are redeemable with the fund at net asset value under the original terms of the partnership agreements and/or subscription agreements and operations of the underlying funds. However, it is possible that these redemption rights may be restricted or eliminated by the funds in the future in accordance with the underlying fund agreements. Due to the nature of the investments held by the funds, changes in market conditions and the economic environment may significantly impact the net asset value of the funds and, consequently, the fair value of the interests in the funds. Furthermore, changes to the liquidity provisions of the funds may significantly impact the fair value of the interest in the funds.

In the third and fourth quarter of 2013, our discontinued operations included impairment charges of $65.0 million ($50.8 million after-tax) and $91.7 million ($71.3 million after-tax), respectively associated with the sale of our FMC Peroxygens segment (See Note 9).
[2]	Amounts in parentheses indicate charges to the consolidated statements of income.
[3]	The reclassification of historical cumulative translation adjustments was the result of the divestiture of our FMC Peroxygens business. The loss recognized from this reclassification is considered permanent for tax purposes and therefore no tax has been provided. See Note 9 for more information. In accordance with accounting guidance, this amount was previously factored into the lower of cost or fair value test associated with the 2013 Peroxygens' asset held for sale write-down charges.

[1]	See Note 7 for details of restructuring and other charges (income). Amounts for the years ended 2014, 2013 and 2012 relate to FMC Agricultural Solutions of $(4.5) million, $32.6 million and $8.5 million; FMC Health and Nutrition of $14.1 million, $1.0 million and $0.7 million; FMC Minerals of $0.1 million, $6.4 million and $13.0 million; and Corporate of $46.8 million, $7.9 million and $5.3 million, respectively.
[2]	Our non-operating pension and postretirement costs are defined as those costs related to interest, expected return on plan assets, amortized actuarial gains and losses and the impacts of any plan curtailments or settlements. These costs are primarily related to changes in pension plan assets and liabilities which are tied to financial market performance and we consider these costs to be outside our operational performance. We exclude these non-operating pension and postretirement costs from our segments as we believe that removing them provides a better understanding of the underlying profitability of our businesses, provides increased transparency and clarity in the performance of our retirement plans and enhances period-over-period comparability. We continue to include the service cost and amortization of prior service cost in our operating segments noted above. We believe these elements reflect the current year operating costs to our businesses for the employment benefits provided to active employees. These expenses are included as a component of the line item "Selling, general and administrative expenses" on our consolidated statements of income.
[3]	Charges are associated with the previously planned separation of our FMC Corporation into two independent public companies. On September 8, 2014, we announced that we would no longer proceed with the planned separation of FMC into two distinct public entities. At that time we announced the acquisition of Cheminova; see Note 3 within these consolidated financial statements for more information. These charges are included within "Business separation costs" on our consolidated income statement. These costs were primarily related to professional fees associated with separation activities within the finance and legal functions through September 8, 2014.
[4]	Charges related to the expensing of the inventory fair value step-up resulting from the application of purchase accounting, legal and professional fees and gains or losses on hedging purchase price associated with the planned or completed acquisitions and costs incurred associated with the divestiture of our FMC Alkali Chemicals division.

In the third and fourth quarter of 2013, our discontinued operations included impairment charges of $65.0 million ($50.8 million after-tax) and $91.7 million ($71.3 million after-tax), respectively associated with the sale of our FMC Peroxygens segment (See Note 9).

At December 31, 2014 and 2013, $42.2 million and $35.0 million of outstanding receivables due from the Argentina government, which primarily represent export tax and valued added tax receivables, were denominated in U.S. dollars. As with all outstanding receivable balances we continually review recoverability by analyzing historical experience, current collection trends and regional business and political factors among other factors. We have further analyzed the recoverability of our outstanding receivables from the Argentina government in light of the current economic and political environment within Argentina, including the recent credit downgrades of local and federal governments and the July 31, 2014 default by the Argentina government on some of its debt obligations. Based on our analysis of the impact of economic conditions in Argentina on our receivables, at this time, we believe the outstanding receivables to be recoverable.
