NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

NOTE 1. GENERAL INFORMATION

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by generally accepted accounting principles (GAAP) in the United States (U.S.). Therefore, this information should be read in conjunction with Freeport-McMoRan Inc.’s (FCX) consolidated financial statements and notes contained in its annual report on Form 10-K for the year ended December 31, 2016. The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. With the exception of the accounting for discontinued operations, assets held for sale, the remeasurement of a pension plan and charges related to a continuing royalty dispute with respect to historical periods at FCX’s mine in Peru, all such adjustments are, in the opinion of management, of a normal recurring nature. As a result of FCX’s sale of its interest in TF Holdings Limited (TFHL), FCX has reported TFHL as discontinued operations for all periods presented in the unaudited consolidated financial statements (refer to Note 2). Operating results for the nine-month period ended September 30, 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

Indonesia Mining. As a result of the first-quarter 2017 regulatory restrictions and uncertainties regarding long-term investment stability, PT Freeport Indonesia (PT-FI) took actions to adjust its cost structure, reduce its workforce and slow investments in its underground development projects and new smelter. These actions included workforce reductions through furlough and voluntary retirement programs. Following the furlough and voluntary retirement programs, a significant number of employees and contractors elected to participate in an illegal strike action beginning in May 2017, and were subsequently deemed to have voluntarily resigned under existing laws and regulations. As a result, PT-FI recorded charges to operating income for employee severance and related costs totaling $9 million for third-quarter 2017 and $113 million for the first nine months of 2017.

Additionally, because of the significant reduction in workforce, PT-FI was required to remeasure its pension assets and pension benefit obligation as of June 30, 2017. The discount rate and rate of compensation increase used for the June 30, 2017, remeasurement were 7.50 percent and 4.00 percent, respectively, compared to the December 31, 2016, discount rate of 8.25 percent and the rate of compensation increase of 8.00 percent. The expected long-term rate of return on the plan assets was unchanged (7.75 percent). The remeasurement and curtailment resulted in the projected benefit obligation declining by $145 million and plan assets declining by $21 million. In addition, PT-FI recognized a curtailment loss of $4 million in second-quarter 2017 and for the first nine months of 2017. As of September 30, 2017, the funded status of PT-FI’s pension plan was a net asset of $36 million (included in other assets in the consolidated balance sheet), compared with a net liability of $90 million (included in other liabilities in the consolidated balance sheet) as of December 31, 2016.

Oil and Gas Properties. During 2016, FCX Oil & Gas LLC (FM O&G, a wholly owned subsidiary of FCX) determined the carrying values of certain of its unevaluated properties were impaired. During the first nine months of 2016, FM O&G transferred $3.2 billion of costs (including $3.1 billion in first-quarter 2016) associated with unevaluated properties to the full cost pool, mostly reflecting impairment of the carrying values of unevaluated properties. The transfer of unevaluated properties to the full cost pool, along with the impact of the reduction in twelve-month historical prices and reserve revisions in 2016 caused net capitalized costs to exceed the related ceiling test limitation under full cost accounting rules. As a result, FM O&G recognized impairment charges of $239 million in third-quarter2016 and $4.3 billion for the first nine months of 2016. Refer to Note 1 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

NOTE 2. DISPOSITIONS

TF Holdings Limited - Discontinued Operations.FCX hada70 percent interest in TFHL, which owns 80 percent of Tenke Fungurume Mining S.A. (TFM or Tenke) located in the Democratic Republic of Congo (DRC). On November 16, 2016, FCX completed the sale of its interest in TFHL to China Molybdenum Co., Ltd. (CMOC) for $2.65 billion in cash (before closing adjustments) and contingent consideration of up to $120 million in cash, consisting of $60 million if the average copper price exceeds $3.50 per pound and $60 million if the average cobalt price exceeds $20 per pound, both during calendar years 2018 and 2019. The contingent consideration is considered a derivative, and at September 30, 2017, the related fair value of $58 million was recorded in other assets on the consolidated balance sheets. During the first nine months of 2017, the fair value of the contingent consideration derivative increased by $45 million ($3 million in third-quarter2017), primarily resulting from higher cobalt prices, and was recorded in net income (loss) from discontinued operations.

In accordance with accounting guidance, FCX has reported the results of operations of TFHL as discontinued operations in the consolidated statements of operations. The consolidated statements of cash flows are reported on a combined basis without separately presenting discontinued operations.

Net income (loss) from discontinued operations in the consolidated statements of operations consists of the following (in millions):

a. In accordance with accounting guidance, amounts are net of (eliminations) recognition of intercompany sales totaling $(53) million in third-quarter2016, $13 million for the first nine months of 2017 and $(125) million for the first nine months of 2016.

b. In accordance with accounting guidance, interest associated with FCX’s term loan that was required to be repaid as a result of the sale of TFHL has been allocated to discontinued operations.

c. Includes a gain of $3 million in third-quarter2017 and $45 million for the first nine months of 2017 associated with the change in the fair value of contingent consideration.

d. In accordance with accounting guidance, an estimated loss on disposal was recorded and adjusted through closing of the transaction in November 2016.

Cash flows from discontinued operations included in the consolidated statements of cash flows for the nine months ended September 30, 2016, follow (in millions):

Net cash provided by operating activities	$	213
Net cash used in investing activities	(71		)
Net cash used in financing activities	(103		)
Increase in cash and cash equivalents in assets held for sale	$	39

Oil and Gas Operations.On July 31, 2017, FM O&G sold certain property interests in the Gulf of Mexico Shelf for cash consideration of $62 million, before closing adjustments, with an effective date of April 1, 2017. On March 17, 2017, FM O&G sold property interests in the Madden area in central Wyoming for cash consideration of $17.5 million, before closing adjustments. Under the full cost accounting rules, the sales resulted in the recognition of gains of $33 million in third-quarter2017 and $49 million for the first nine months of 2017 because the reserves associated with these properties were significant to the full cost pool.

On June 17, 2016, FM O&G sold certain oil and gas royalty interests for cash consideration of $102 million, before closing adjustments. In addition, on July 25, 2016, FM O&G sold its Haynesville shale assets for cash consideration of $87 million, before closing adjustments. Under the full cost accounting rules, the proceeds from these transactions were recorded as a reduction to capitalized oil and gas properties, with no gain or loss recognition for the first nine months of2016 because the reserves were not significant to the full cost pool.

Morenci. On May 31, 2016, FCX sold a 13 percent undivided interest in its Morenci unincorporated joint venture to SMM Morenci, Inc. for $1.0 billion in cash. FCX recorded a $576 million gain for the first nine months of2016 and used losses to offset cash taxes on the transaction. A portion of the proceeds from the transaction was used to repay borrowings under FCX's unsecured bank term loan and revolving credit facility. As a result of the transaction, the unincorporated joint venture is owned 72 percent by FCX, 15 percent by Sumitomo Metal Mining Arizona, Inc. and 13 percent by SMM Morenci, Inc.

Timok. On May 2, 2016, Freeport Minerals Corporation (FMC), a wholly owned subsidiary of FCX, sold an interest in the Timok exploration project in Serbia to Global Reservoir Minerals Inc. (now known as Nevsun Resources, Ltd.) for consideration of $135 million in cash and contingent consideration of up to $107 million payable to FCX in stages upon achievement of defined development milestones. As a result of this transaction, FCX recorded a gain of $133 million for the first nine months of2016, and no amounts were recorded for contingent consideration under the loss recovery approach.

Assets Held for Sale. Freeport Cobalt includes the large-scale cobalt refinery in Kokkola, Finland, and the related sales and marketing business, in which FCX owns an effective 56 percent interest. Kisanfu is a copper and cobalt exploration project, located near Tenke, in which FCX holds a 100 percent interest. As a result of the sale of TFHL, FCX expects to sell its interest in Freeport Cobalt and Kisanfu, and the assets and liabilities of Freeport Cobalt and Kisanfu are classified as held for sale in the consolidated balance sheets. During the first nine months of2017, a favorable adjustment of $13 million was recorded in net gain on sales of assets in the consolidated statements of operations associated with the estimated fair value less costs to sell for the Kisanfu exploration project. The adjustment was limited to the reduction in the carrying value when the Kisanfu exploration project was initially classified as held for sale in November 2016.

NOTE 3. EARNINGS PER SHARE

FCX calculates its basic net income (loss) per share of common stock under the two-class method and calculates its diluted net income (loss) per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income (loss) per share of common stock was computed by dividing net income (loss) attributable to common stockholders (after deducting accumulated dividends and undistributed earnings to participating securities) by the weighted-average shares of common stock outstanding during the period. Diluted net income (loss) per share of common stock was calculated by including the basic weighted-average shares of common stock outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be anti-dilutive.

Reconciliations of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted net income (loss) per share follow (in millions, except per share amounts):

NOTE 5. INCOME TAXES

Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. FCX’s consolidated effective income tax rate was 47 percent for the first nine months of 2017 and (2) percent for first nine months of 2016. Geographic sources of FCX’s (provision for) benefit from income taxes follow (in millions):

	Three Months Ended							Nine Months Ended

a. Includes net tax (charges) credits of $(10) million for third-quarter2017 and $21 million for the first nine months of 2017 associated with alternative minimum tax credit carryforwards. The third quarter and first nine months of 2016 include net tax credits of $332 million and $290 million, respectively, associated with alternative minimum tax credits, changes to valuation allowances and net operating loss carryback claims.

b. Includes net charges of $2 million associated with the Cerro Verde mining royalties dispute, consisting of tax charges of $127 million for disputed royalties and other related mining taxes for the period October 2011 through the year 2013 (when royalties were determined based on operating income), mostly offset by a tax benefit of $125 million associated with disputed royalties and other related mining taxes for the period December 2006 through the year 2013.

As a result of the unfavorable Peruvian Supreme Court ruling on the Cerro Verde royalty dispute, FCX recorded pre-tax charges of $357 million to income from continuing operations and $2 million of net tax expense for the first nine months of 2017. FCX’s consolidated effective income tax rate was 39 percent for the first nine months of 2017 excluding these charges.

As a result of the impairment to U.S. oil and gas properties, FCX recorded tax charges of $1.6 billion for the first nine months of 2016 to establish a valuation allowance primarily against U.S. federal and state deferred tax assets that will not generate a future benefit. FCX’s consolidated effective income tax rate was 32 percent for the first nine months of 2016 excluding these tax charges.

Revolving Credit Facility. At September 30, 2017, there were no borrowings outstanding and $36 million in letters of credit issued under FCX’s revolving credit facility, resulting in availability of approximately $3.5 billion, of which approximately $1.5 billion could be used for additional letters of credit.

Senior Notes Issued by FCX. In March 2017, FCX’s 2.15% Senior Notes matured, and the $500 million outstanding principal balance was repaid.

Cerro Verde Credit Facility and Shareholder Loans. In June 2017, Cerro Verde’s credit facility was amended to increase the commitment by $225 million to $1.5 billion, modify the amortization schedule and to extend the maturity date to June 19, 2022. The amended credit facility amortizes in four installments, with $225 million due on December 31, 2020, $225 million due on June 30, 2021, $525 million due on December 31, 2021, and the remaining balance due on the maturity date of June 19, 2022. All other terms, including the interest rates, remain the same. The interest rate on Cerro Verde's credit facility was 3.14 percent at September 30, 2017. Cerro Verde used proceeds from its amended credit facility plus available cash to repay the balance of its shareholder loans in June 2017. Refer to Note 8 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

Exchanges and Early Extinguishment of Debt. During third-quarter2017, FCX redeemed in full certain senior notes. A summary of these early debt extinguishments follows (in millions):

	Principal Amount		Net Adjustments		Book Value		Redemption Value		Gain
FCX 6.125% Senior Notes due 2019	$	179	$	5	$	184	$	182	$	2
FM O&G 6.125% Senior Notes due 2019	58		2		60		59		1

	$	543	$	23	$	566	$	555	$	11

Partially offsetting the $11 million gain on early extinguishment of certain senior notes was a net loss of $3 million, primarily associated with the modification of Cerro Verde’s credit facility in second-quarter 2017.

During the second and third quarters of 2016, FCX redeemed certain senior notes in exchange for its common stock, which resulted in gains of $15 million in third-quarter2016 and $54 million for the first nine months of 2016. Partially offsetting the gains were $3 million in losses, primarily associated with the modification of FCX’s revolving credit facility in first-quarter 2016. Refer to Notes 8 and 10 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

Interest Expense, Net. Consolidated interest costs from continuing operations (before capitalization and excluding $141 million of interest expense associated with disputed Cerro Verde royalties recorded in third-quarter2017) totaled $196 million in third-quarter2017, $211 million in third-quarter2016, $583 million for the first nine months of 2017 and $647 million for the first nine months of 2016. Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $33 million in third-quarter2017, $24 million in third-quarter2016, $91 million for the first nine months of 2017 and $66 million for the first nine months of 2016. Capitalized interest added to oil and gas properties not subject to amortization totaled $7 million for the first nine months of 2016 (none in third-quarter2016 or 2017).

NOTE 7. FINANCIAL INSTRUMENTS

FCX does not purchase, hold or sell derivative financial instruments unless there is an existing asset or obligation, or it anticipates a future activity that is likely to occur and will result in exposure to market risks, which FCX intends to offset or mitigate. FCX does not enter into any derivative financial instruments for speculative purposes, but has entered into derivative financial instruments in limited instances to achieve specific objectives. These objectives principally relate to managing risks associated with commodity price changes, foreign currency exchange rates and interest rates.

Commodity Contracts. From time to time, FCX has entered into derivative contracts to hedge the market risk associated with fluctuations in the prices of commodities it purchases and sells. Derivative financial instruments used by FCX to manage its risks do not contain credit risk-related contingent provisions. As of September 30, 2017, and December 31, 2016, FCX had no price protection contracts relating to its mine production. A discussion of FCX’s derivative contracts and programs follows.

Derivatives Designated as Hedging Instruments – Fair Value Hedges

Copper Futures and Swap Contracts. Some of FCX’s U.S. copper rod customers request a fixed market price instead of the Commodity Exchange Inc. (COMEX) average copper price in the month of shipment. FCX hedges this price exposure in a manner that allows it to receive the COMEX average price in the month of shipment while the customers pay the fixed price they requested. FCX accomplishes this by entering into copper futures or swap contracts. Hedging gains or losses from these copper futures and swap contracts are recorded in revenues. FCX did not have any significant gains or losses resulting from hedge ineffectiveness during the nine-month periods ended September 30, 2017 and 2016. At September 30, 2017, FCX held copper futures and swap contracts that qualified for hedge accounting for 46 million pounds at an average contract price of $2.83 per pound, with maturities through June 2019.

Derivatives Not Designated as Hedging Instruments

Embedded Derivatives. As described in Note 1 to FCX’s annual report on Form 10-K for the year ended December 31, 2016, under “Revenue Recognition,” certain FCX copper concentrate, copper cathode and gold sales contracts provide for provisional pricing primarily based on the London Metal Exchange (LME) copper price or the COMEX copper price and the London Bullion Market Association (London) gold price at the time of shipment as specified in the contract. Similarly, FCX purchases copper under contracts that provide for provisional pricing. FCX applies the normal purchases and normal sales scope exception in accordance with derivatives and hedge accounting guidance to the host sales agreements since the contracts do not allow for net settlement and always result in physical delivery. Sales and purchases with a provisional sales price contain an embedded derivative (i.e., the price settlement mechanism is settled after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale or purchase of the metals contained in the concentrate or cathode at the then-current LME or COMEX copper price or the London gold price as defined in the contract. Mark-to-market price fluctuations from these embedded derivatives related to continuing operations are recorded through the settlement date and are reflected in revenues for sales contracts and in cost of sales as production and delivery costs for purchase contracts. Mark-to-market price fluctuations associated with embedded derivatives for discontinued operations, which were minimal, are included in discontinued operations for all periods presented in these financial statements.

A summary of FCX’s embedded derivatives at September 30, 2017, follows:

	Open Positions	Average Price Per Unit				Maturities Through
		Contract		Market
Embedded derivatives in provisional sales contracts:
Copper (millions of pounds)	546	$	2.84	$	2.93	February 2018
Gold (thousands of ounces)	194	1,318		1,287		December 2017
Embedded derivatives in provisional purchase contracts:
Copper (millions of pounds)	155	2.83		2.93		January 2018

Copper Forward Contracts. Atlantic Copper, FCX’s wholly owned smelting and refining unit in Spain, enters into copper forward contracts designed to hedge its copper price risk whenever its physical purchases and sales pricing periods do not match. These economic hedge transactions are intended to hedge against changes in copper prices, with the mark-to-market hedging gains or losses recorded in cost of sales. At September 30, 2017, Atlantic Copper held net copper forward purchase contracts for 5 million pounds at an average contract price of $2.95 per pound, with maturities through October 2017.

FCX’s commodity contracts have netting arrangements with counterparties with which the right of offset exists, and it is FCX’s policy to generally offset balances by counterparty on its balance sheet. FCX’s embedded derivatives on provisional sales/purchase contracts are netted with the corresponding outstanding receivable/payable balances. A summary of these unsettled commodity contracts that are offset in the balance sheets follows (in millions):

Credit Risk. FCX is exposed to credit loss when financial institutions with which it has entered into derivative transactions (commodity, foreign exchange and interest rate swaps) are unable to pay. To minimize the risk of such losses, FCX uses counterparties that meet certain credit requirements and periodically reviews the creditworthiness of these counterparties. FCX does not anticipate that any of the counterparties it deals with will default on their obligations. As of September 30, 2017, the maximum amount of credit exposure associated with derivative transactions was $78 million.

Other Financial Instruments. Other financial instruments include cash and cash equivalents, accounts receivable, restricted cash, investment securities, legally restricted funds, accounts payable and accrued liabilities, and long-term debt. The carrying value for cash and cash equivalents (which included time deposits of $1.9 billion at September 30, 2017, and $64 million at December 31, 2016), accounts receivable, restricted cash, and accounts payable and accrued liabilities approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 8 for the fair values of investment securities, legally restricted funds and long-term debt).

In addition, as of September 30, 2017, FCX has contingent consideration assets related to certain 2016 asset sales (refer to Note 8 for the related fair value and to Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion of these instruments).

17

NOTE 8. FAIR VALUE MEASUREMENT

Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). FCX recognizes transfers between levels at the end of the reporting period. FCX did not have any significant transfers in or out of Level 1, 2 or 3 for third-quarter2017.

FCX’s financial instruments are recorded on the consolidated balance sheets at fair value except for contingent consideration associated with the sale of the Deepwater Gulf of Mexico (GOM) oil and gas properties (which was recorded under the loss recovery approach) and debt. A summary of the carrying amount and fair value of FCX’s financial instruments, other than cash and cash equivalents, accounts receivable, restricted cash, and accounts payable and accrued liabilities (refer to Note 7) follows (in millions):

Valuation Techniques. The U.S. core fixed income fund is valued at net asset value (NAV). The fund strategy seeks total return consisting of income and capital appreciation primarily by investing in a broad range of investment-grade debt securities, including U.S. government obligations, corporate bonds, mortgage-backed securities, asset-backed securities and money market instruments. There are no restrictions on redemptions (which are usually within one business day of notice).

Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

Equity securities are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy.

Fixed income securities (government securities, corporate bonds, asset-backed securities, collateralized mortgage-backed securities and municipal bonds) are valued using a bid-evaluation price or a mid-evaluation price. A bid-evaluation price is an estimated price at which a dealer would pay for a security. A mid-evaluation price is the average of the estimated price at which a dealer would sell a security and the estimated price at which a dealer would pay for a security. These evaluations are based on quoted prices, if available, or models that use observable inputs and, as such, are classified within Level 2 of the fair value hierarchy.

FCX’s embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales are valued using only quoted monthly LME or COMEX copper forward prices and the London gold forward price at each reporting date based on the month of maturity (refer to Note 7 for further discussion); however, FCX’s contracts themselves are not traded on an exchange. As a result, these derivatives are classified within Level 2 of the fair value hierarchy.

FCX’s derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 7 for further discussion). Certain of these contracts are traded on the over-the-counter market and are classified within Level 2 of the fair value hierarchy based on COMEX and LME forward prices.

The fair value of contingent consideration for the sales of TFHL and onshore California oil and gas properties is calculated based on average commodity price forecasts through applicable maturity dates using a Monte Carlo simulation model. The models use various observable inputs, including Brent crude oil forward prices, historical copper and cobalt prices, volatilities, discount rates and settlement terms. As a result, these contingent consideration assets are classified within Level 2 of the fair value hierarchy.

The fair value of contingent consideration for the sale of Deepwater GOM oil and gas properties is calculated based on a discounted cash flow model using inputs that include third-party reserve estimates, production rates, production timing and discount rates. Because significant inputs are not observable in the market, the contingent consideration is classified within Level 3 of the fair value hierarchy.

The December 31, 2016, fair value of contingent payments for the settlements of drilling rig contracts was calculated based on the average price forecasts of West Texas Intermediate (WTI) crude oil over the 12-month period ending June 30, 2017, using a mean-reverting model. The model used various observable inputs, including WTI crude oil forward prices, volatilities, discount rate and settlement terms. As a result, these contingent payments were classified within Level 2 of the fair value hierarchy. The contingency period for FM O&G’s drilling rig contract settlements ended June 30, 2017, and no additional amounts were paid.

Long-term debt, including current portion, is valued using available market quotes and, as such, is classified within Level 2 of the fair value hierarchy.

The techniques described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with other market participants, the use of different techniques or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the techniques used at September 30, 2017, as compared to those techniques used at December 31, 2016.

A summary of the changes in the fair value of FCX’s Level 3 instrument, contingent consideration for the sale of the Deepwater GOM oil and gas properties, during the first nine months of2017 follows (in millions):

Fair value at January 1, 2017	$	135
Net unrealized gain related to assets still held at the end of the period	3
Fair value at September 30, 2017	$	138

NOTE 9. CONTINGENCIES AND COMMITMENTS

Environmental

Historical Smelter Sites — Borough of Carteret

As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, from 1920 until 1986, United States Metal Refining Company (USMR), an indirect wholly owned subsidiary of Cyprus Amax Minerals Company, owned and operated a copper smelter and refinery in the Borough of Carteret, New Jersey, on the banks of the Arthur Kill (a narrow waterway that separates New Jersey from Staten Island). As a result of recent off-site soil sampling in public and private areas near the former smelter, FCX increased its associated environmental obligation for known and potential off-site environmental remediation by recording a $59 million charge to operating income in third-quarter 2017. Additional sampling is ongoing and could result in additional adjustments to the related environmental remediation obligation.

Uranium Mining Sites

As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, the Department of Justice, the U.S. Environmental Protection Agency, the Navajo Nation and two FCX-related subsidiaries reached an agreement regarding the scope of environmental investigation and remediation work for 94 former uranium mining sites on tribal lands, and the related financial contributions of the U.S. government and the FCX subsidiaries. The related Consent Decree was approved by the U.S. District Court for the District of Arizona in second-quarter 2017. Based on updated cash flow and timing estimates, FCX reduced its associated obligation for that contingency by recording a $41 million credit to operating income in second-quarter 2017 after receiving court approval of the Consent Decree.

Litigation

During third-quarter2017, there were no significant updates to previously reported legal proceedings included in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.

Tax and Other Matters

Cerro Verde Royalty Dispute

As reported in FCX’s annual report on Form 10-K for the year ended December 31, 2016, and as subsequently updated in Note 9 of FCX’s quarterly report on Form 10-Q for the quarter ended June 30, 2017, SUNAT, Peru’s national tax authority, has assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006, for the period December 2006 to September 2011. Cerro Verde contested these assessments because it believes its 1998 stability agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing those minerals. No assessments have been issued for the period from October 2011 to December 2013, and no assessments can be issued for years after 2013, as Cerro Verde began paying royalties on all of its production in January 2014 under its new 15-year stability agreement. Since 2014, Cerro Verde has been paying the disputed assessments for the period December 2006 through December 2008 under an installment program ($135 million paid by Cerro Verde through September 30, 2017).

In October 2017, the Peruvian Supreme Court issued a ruling in favor of SUNAT that the assessments of royalties for the year 2008 on ore processed by the Cerro Verde concentrator were proper under Peruvian law.

21

As a result of the unfavorable Peruvian Supreme Court ruling on the 2008 royalty dispute, Cerro Verde recorded pre-tax charges totaling $357 million ($359 million including net tax charges and $188 million net of noncontrolling interests) in third-quarter 2017, consisting of $240 million in royalty assessments, $147 million of penalties and interest related to the December 2006 to December 2008 assessments, and $97 million for related items (primarily associated with the special mining tax and net assets tax) that Cerro Verde would have incurred under the view that its concentrator was not stabilized.

A summary of the charges recorded in third-quarter 2017 for the Cerro Verde royalty dispute follows (in millions):

Royalty and related assessment charges:
	Production and delivery	$	216		a
	Interest expense, net	141
	Provision for income taxes	2			b
Net loss attributable to noncontrolling interests		(171		)
		$	188

a. Includes $176 million related to disputed royalty assessments for the period from December 2006 to September 2011 (when royalties were determined based on revenues), $6 million of penalties related to the December 2006 to December 2008 royalty assessments and $34 million primarily associated with the net assets tax.

b. Includes tax charges of $127 million for disputed royalties ($64 million) and other related mining taxes ($63 million) for the period October 2011 through the year 2013 when royalties were determined based on operating income, mostly offset by a tax benefit of $125 million associated with disputed royalties and other related mining taxes for the period December 2006 through the year 2013.

Cerro Verde acted in good faith in applying the provisions of its 1998 stability agreement and continues to evaluate alternatives to defend its rights. Cerro Verde intends to seek a waiver available under Peruvian law of penalties and interest associated with this matter and has not recorded charges for potential unpaid penalties and interest totaling $360 million ($193 million net of noncontrolling interests) at September 30, 2017, as FCX believes that Cerro Verde should be successful under Peruvian law in obtaining a waiver. Cerro Verde also intends to file a reimbursement claim with SUNAT for penalties and interest paid under the installment plan for the December 2006 to December 2008 assessments, and may have claims for reimbursement of payments it would not have made in the absence of the stabilization agreement, such as the overpayments made for a special (voluntary) levy (GEM), import duties and civil association contributions. No amounts have been recorded for these potential gain contingencies at September 30, 2017.

Other Peru Tax Matters

There were no significant changes to other Peru tax matters during third-quarter2017 (refer to Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016).

Indonesia Tax Matters

The following information includes a discussion of updates to previously reported Indonesia tax matters included in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.

PT-FI received assessments from the local regional tax authority in Papua, Indonesia, for additional taxes and penalties related to surface water taxes for the period from January 2011 through September 2017. PT-FI is filing objections to these assessments. During 2017, the Indonesia Tax Court issued rulings against PT-FI with respect to assessments for additional taxes and penalties for the period from January 2011 through December 2015 in the amount of $402 million (based on the exchange rate as of September 30, 2017, and including $240 million in penalties). The aggregate amount of assessments received from January 2016 through September 2017 was an additional $114 million, including penalties (based on the exchange rate as of September 30, 2017). No charges have been recorded for these assessments as of September 30, 2017, because PT-FI believes its Contract of Work (COW) exempts it from these payments and that it has the right to contest these assessments (in which FCX estimates the total exposure based on the exchange rate as of September 30, 2017, totals $516 million, including penalties) in the Indonesia Tax Court and ultimately the Indonesia Supreme Court. As of November 7, 2017, PT-FI has not paid and does not intend to pay these assessments unless there is a mechanism established to secure a refund for any such payments upon the final court decision. Additionally, PT-FI is seeking to address this matter in connection with the ongoing negotiations with the Indonesian government to resolve PT-FI’s long-term operating rights.

22

Indonesia Mining Contract. The following information includes updates to the discussion of PT-FI’s COW included in Note 13 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.

In January and February 2017, the Indonesian government issued new regulations to address the export of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. The new regulations permit the continuation of copper concentrate exports for a five-year period through January 2022, subject to various conditions, including conversion from a contract of work to a special operating license (known as an IUPK, which does not provide the same level of fiscal and legal protections as PT-FI’s COW, which remains in effect), a commitment to the completion of smelter construction in five years and payment of export duties to be determined by the Ministry of Finance. In addition, the new regulations enable application for an extension of operating rights five years before expiration of the IUPK and require foreign IUPK holders to divest a 51 percent interest in the licensed entity to Indonesian interests no later than the tenth year of production. Export licenses would be valid for one-year periods, subject to review every six months, depending on smelter construction progress.

Following the issuance of the January and February 2017 regulations and discussions with the Indonesian government, PT-FI advised the government that it was prepared to convert its COW to an IUPK, subject to obtaining an investment stability agreement providing contractual rights with the same level of legal and fiscal certainty enumerated under its COW, and provided that the COW would remain in effect until it is replaced by a mutually satisfactory alternative. PT-FI also committed to commence construction of a new smelter during a five-year time frame, following approval of the extension of its long-term operating rights.

On January 12, 2017, PT-FI suspended exports in response to Indonesian regulations adopted in January 2014. In addition, as a result of labor disturbances and a delay in the renewal of its export license for anode slimes, PT Smelting’s operations (PT-FI’s 25 percent-owned smelter in Indonesia) were shut down from January 19, 2017, until early March 2017. On February 10, 2017, PT-FI was forced to suspend production as a result of limited storage capacity at PT-FI and PT Smelting. On April 21, 2017, the Indonesian government issued a permit to PT-FI that allowed exports to resume for a six-month period, and PT-FI commenced export shipments.

In mid-February 2017, pursuant to the COW’s dispute resolution process, PT-FI provided formal notice to the Indonesian government of an impending dispute listing the government's breaches and violations of the COW. PT-FI continues to reserve its rights under these provisions.

As a result of the 2017 regulatory restrictions and uncertainties regarding long-term investment stability, PT-FI took actions to adjust its cost structure, slow investments in its underground development projects and new smelter, and place certain of its workforce on furlough programs.

In late March 2017, the Indonesian government amended the regulations to enable PT-FI to retain its COW until replaced with an IUPK accompanied by an investment stability agreement, and to grant PT-FI a temporary IUPK through October 10, 2017, that would allow concentrate exports to resume during this period. In April 2017, PT-FI entered into a Memorandum of Understanding with the Indonesian government confirming that the COW would continue to be valid and honored until replaced by a mutually agreed IUPK and investment stability agreement. PT-FI agreed to continue to pay a five percent export duty during this period.

In August 2017, FCX and the Indonesian government reached an understanding on a framework that would resolve PT-FI’s long-term operating rights. This framework includes (i) conversion from the COW to an IUPK providing PT-FI with long-term operating rights through 2041, (ii) Indonesian government certainty of fiscal and legal terms during the term of the IUPK, (iii) PT-FI commitment to construct a new smelter in Indonesia within five years of reaching a definitive agreement, and (iv) divestment of 51 percent of the project area interests to Indonesian participants at fair market value structured so that FCX retains control over operations and governance of PT-FI. FCX cannot currently predict whether there will be any material accounting and tax implications associated with the divestment.

The framework requires documentation and execution of a definitive agreement, which must be approved by the FCX Board of Directors and joint venture partner Rio Tinto. The parties continue to negotiate to reach agreement on important aspects of implementation of the framework, including the timing and process of divestment, governance matters, and the determination of fair market value, and to complete documentation on a comprehensive agreement for PT-FI’s operations through 2041. The parties have expressed a mutual objective of completing the negotiations and documentation during 2017.

23

In October 2017, the Indonesian government extended PT-FI’s export rights to December 31, 2017, while negotiations to reach and document a comprehensive long-term definitive agreement based on the agreed framework continue.

Until a definitive agreement is reached, PT-FI has reserved all rights under its COW, including pursuing arbitration under the dispute resolution provisions.

NOTE 10. BUSINESS SEGMENTS

FCX has organized its mining operations into four primary divisions – North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX’s reportable segments, which include the Morenci, Cerro Verde and Grasberg (Indonesia Mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining.

FCX’s reportable segments previously included U.S. Oil & Gas operations. During 2016, FCX completed the sales of its Deepwater Gulf of Mexico, onshore California and Haynesville oil and gas properties. As a result, beginning in 2017, the U.S. oil and gas operations no longer qualify as a reportable segment, and oil and gas results for all periods presented have been included in Corporate, Other & Eliminations in the following tables. Refer to Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for additional information.

Intersegment sales between FCX’s business segments are based on terms similar to arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums.

FCX defers recognizing profits on sales from its mines to other divisions, including Atlantic Copper (FCX’s wholly owned smelter and refinery in Spain) and on 25 percent of PT-FI’s sales to PT Smelting (PT-FI’s 25-percent-owned smelter and refinery in Indonesia), until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX’s net deferred profits and quarterly earnings.

FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level (included in Corporate, Other & Eliminations), whereas foreign income taxes are recorded and managed at the applicable country level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs, along with some selling, general and administrative costs, are not allocated to the operating divisions or individual segments. Accordingly, the following segment information reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

NOTE 12. NEW ACCOUNTING STANDARDS

In May 2014, the Financial Accounting Standards Board (FASB) issued an Accounting Standard Update (ASU) that provides a single comprehensive revenue recognition model, which will replace most existing revenue recognition guidance, and also requires expanded disclosures. The core principle of the model is that revenue is recognized when control of goods or services has been transferred to customers at an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods within that reporting period. Early adoption is permitted for annual reporting periods beginning after December 15, 2016, and interim reporting periods within that reporting period. FCX will adopt this ASU January 1, 2018, and currently expects to apply the modified retrospective approach under which any cumulative effect adjustment would be recorded to retained earnings as of the adoption date. FCX has substantially completed its review of the impact of this guidance, and based on the terms of its sales contracts, does not expect the guidance to have any impact on its revenue recognition policies or processes. FCX continues to review the impact of the new guidance on its financial reporting and disclosures.

In March 2016, FASB issued an ASU that simplifies various aspects of the accounting for share-based payment transactions, including the income tax consequences, statutory tax withholding requirements, an accounting policy election for forfeitures and the classification on the statement of cash flows. FCX adopted this ASU effective January 1, 2017, and adoption did not have a material impact on its financial statements.

In March 2017, FASB issued an ASU that changes how entities with a defined benefit pension or other postretirement benefit plans present net periodic benefit cost in the income statement. This ASU requires the service cost component of net periodic benefit cost to be presented in the same income statement line item or items as other compensation costs for those employees who are receiving the retirement benefit. In addition, only the service cost component is eligible for capitalization when applicable (i.e., as a cost of inventory or an internally constructed asset). The other components of net periodic benefit cost are required to be presented separately from the service cost component and outside of operating income. These other components of net periodic benefit cost are not eligible for capitalization, and the income statement line item or items must be disclosed. For public entities, this ASU is effective for annual periods beginning after December 15, 2017, and interim reporting periods within that reporting period. Early adoption is permitted. FCX will adopt this ASU on January 1, 2018, and does not expect it to have a material impact on its presentation of the statements of operations.

NOTE 13. SUBSEQUENT EVENTS

FCX evaluated events after September 30, 2017, and through the date the consolidated financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these consolidated financial statements.

REVIEW REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF

FREEPORT-McMoRan INC.

We have reviewed the consolidated balance sheet of Freeport-McMoRan Inc. as of September 30, 2017, and the related consolidated statements of operations and comprehensive income (loss) for the three- and nine-month periods ended September 30, 2017 and 2016, the consolidated statements of cash flows for the nine-month periods ended September 30, 2017 and 2016, and the consolidated statement of equity for the nine-month period ended September 30, 2017. These financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Freeport-McMoRan Inc. as of December 31, 2016, and the related consolidated statements of operations, comprehensive loss, cash flows and equity for the year then ended (not presented herein) and we expressed an unqualified audit opinion on those consolidated financial statements in our report dated February 24, 2017. In our opinion, the accompanying consolidated balance sheet of Freeport-McMoRan Inc. as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

In Management’s Discussion and Analysis of Financial Condition and Results of Operations, “we,” “us” and “our” refer to Freeport-McMoRan Inc. (FCX) and its consolidated subsidiaries. You should read this discussion in conjunction with our consolidated financial statements, the related Management’s Discussion and Analysis of Financial Condition and Results of Operations and the discussion of our Business and Properties in our annual report on Form 10-K for the year ended December 31, 2016, filed with the United States (U.S.) Securities and Exchange Commission (SEC). The results of operations reported and summarized below are not necessarily indicative of future operating results (refer to “Cautionary Statement” for further discussion). References to “Notes” are Notes included in our Notes to Consolidated Financial Statements. Throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations, all references to earnings or losses per share are on a diluted basis. Additionally, in accordance with accounting guidelines, TF Holdings Limited (TFHL), through which we held a controlling interest in the Tenke Fungurume (Tenke) mine until it was sold on November 16, 2016, is reported as a discontinued operation for all periods presented.

OVERVIEW

We are a leading international mining company with headquarters in Phoenix, Arizona. We operate large, long-lived, geographically diverse assets with significant proven and probable reserves of copper, gold and molybdenum. We are the world’s largest publicly traded copper producer. Our portfolio of assets includes the Grasberg minerals district in Indonesia, one of the world’s largest copper and gold deposits; and significant mining operations in the Americas, including the large-scale Morenci minerals district in North America and the Cerro Verde operation in South America.

Net income (loss) attributable to common stock totaled $280 million in third-quarter2017, $217 million in third-quarter2016, $776 million for the first nine months of 2017 and $(4.4) billion for the first nine months of 2016. The 2017 periods, compared with the 2016 periods, benefited from higher copper prices and higher gold sales volumes, partly offset by lower copper sales volumes and higher tax expense. The 2017 periods also include a net charge of $188 million for accruals related to Peruvian government claims for disputed royalties (refer to “Operations – South America Mining” for further discussion). The first nine months of 2016 included significant charges for the impairment of oil and gas properties and other oil and gas charges for drillship settlements/idle rig costs, inventory adjustments, asset impairment and restructuring, partly offset by net gains on sales of assets. Refer to “Consolidated Results” for further discussion.

At September 30, 2017, we had $5.0 billion in consolidated cash and cash equivalents and $14.8 billion in total debt. We had no borrowings and $3.5 billion available under our revolving credit facility. Refer to Note 6 for further discussion of debt.

We continue to manage production, exploration and administrative costs and capital spending and, subject to commodity prices and operational results, expect to generate operating cash flows in excess of capital expenditures for the years 2017 and 2018.

We believe that we have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. We are pursuing opportunities to enhance our mines’ net present values, and we continue to advance studies for future development of our copper resources, the timing of which will be dependent on market conditions.

In August 2017, we reached an understanding with the Indonesian government on a framework that would resolve PT Freeport Indonesia’s (PT-FI) long-term operating rights. This framework includes (i) conversion from the Contract of Work (COW) to a new operating license (IUPK) providing PT-FI with long-term operating rights through 2041, (ii) Indonesian government certainty of fiscal and legal terms during the term of the IUPK, (iii) PT-FI commitment to construct a new smelter in Indonesia within five years of reaching a definitive agreement, and (iv) divestment of 51 percent of the project area interests to Indonesian participants at fair market value structured so that we retain control over operations and governance of PT-FI.

The framework requires documentation and execution of a definitive agreement, which must be approved by our Board of Directors (Board) and joint venture partner Rio Tinto. The parties continue to negotiate to reach agreement on important aspects of implementation of the framework, including the timing and process of divestment, governance matters, and the determination of fair market value, and to complete documentation on a comprehensive agreement for PT-FI’s operations through 2041. The parties have expressed a mutual objective of

34

completing the negotiations and documentation during 2017. In October 2017, the Indonesian government extended PT-FI’s export rights to December 31, 2017, while negotiations to reach and document a comprehensive long-term definitive agreement based on the agreed framework continue. Until a definitive agreement is reached, PT-FI has reserved all rights under its COW, including pursuing arbitration under the dispute resolution provisions. Refer to “Operations – Indonesia Mining” for further discussion.

OUTLOOK

We view the long-term outlook for our business positively, supported by limitations on supplies of copper and by the requirements for copper in the world’s economy. Our financial results vary as a result of fluctuations in market prices primarily for copper, gold and molybdenum, as well as other factors. World market prices for these commodities have historically fluctuated and are affected by numerous factors beyond our control. Because we cannot control the price of our products, the key measures that management focuses on in operating our business are sales volumes, unit net cash costs, operating cash flow and capital expenditures.

Refer to “Operations – Indonesia Mining” for further discussion of Indonesia regulatory matters, which could have a significant impact on future results.

Sales Volumes

Following are our projected consolidated sales volumes for the year 2017:

Copper (millions of recoverable pounds):
North America copper mines	1,470
South America mining	1,230
Indonesia mining	1,010
Total	3,710
Gold (thousands of recoverable ounces)	1,600
Molybdenum (millions of recoverable pounds)	94	a

a. Projected molybdenum sales include 34 million pounds produced by our Molybdenum mines and 60 million pounds produced by our North America and South America copper mines.

Consolidated sales volumes for fourth-quarter2017 are expected to approximate 1.0 billion pounds of copper, 625 thousand ounces of gold and 23 million pounds of molybdenum.

Projected sales volumes are dependent on operational performance and other factors. For other important factors that could cause results to differ materially from projections, refer to “Cautionary Statement.”

Unit Net Cash Costs

Assuming average prices of $1,300 per ounce of gold and $8.00 per pound of molybdenum for fourth-quarter2017 and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for our copper mines are expected to average $1.19 per pound of copper for the year 2017. The impact of price changes for fourth-quarter2017 on consolidated unit net cash costs would approximate $0.01 per pound for each $50 per ounce change in the average price of gold and $0.005 per pound for each $2 per pound change in the average price of molybdenum. Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices, primarily for gold and molybdenum. Refer to “Consolidated Results – Production and Delivery Costs” for further discussion of consolidated production costs for our mining operations.

Consolidated Operating Cash Flow

Our consolidated operating cash flows vary with sales volumes, prices realized from copper, gold and molybdenum sales, production costs, income taxes, other working capital changes and other factors. Based on current sales volume and cost estimates, and assuming average prices of $3.00 per pound of copper, $1,300 per ounce of gold and $8.00 per pound of molybdenum for fourth-quarter2017, our consolidated operating cash flows are estimated to approximate $4.3 billion for the year 2017 (including $0.5 billion in working capital sources and tax payments). Projected consolidated operating cash flows for the year 2017 also reflect an estimated income tax provision of $1.3 billion (refer to “Consolidated Results – Income Taxes” for further discussion of our projected income tax rate for the year 2017). The impact of price changes during fourth-quarter2017 on operating cash flows would approximate $80

35

million for each $0.10 per pound change in the average price of copper, $20 million for each $50 per ounce change in the average price of gold and $15 million for each $2 per pound change in the average price of molybdenum.

Consolidated Capital Expenditures

Consolidated capital expenditures are expected to approximate $1.5 billion for the year 2017, including $0.9 billion for major mining projects, primarily for underground development activities at Grasberg. As a result of regulatory uncertainty, PT-FI has slowed investments in its underground development projects. If PT-FI is unable to reach a definitive agreement with the Indonesian government on its long-term mining rights, we intend to reduce or defer investments significantly in underground development projects.

MARKETS

World prices for copper, gold and molybdenum can fluctuate significantly. During the period from January 2007 through September 2017, the London Metal Exchange (LME) spot copper price varied from a low of $1.26 per pound in 2008 to a record high of $4.60 per pound in 2011; the London Bullion Market Association (London) PM gold price fluctuated from a low of $608 per ounce in 2007 to a record high of $1,895 per ounce in 2011; and the Metals Week Molybdenum Dealer Oxide weekly average price ranged from a low of $4.46 per pound in 2015 to a high of $33.88 per pound in 2008. Copper, gold and molybdenum prices are affected by numerous factors beyond our control as described further in “Risk Factors” contained in Part I, Item 1A. of our annual report on Form 10-K for the year ended December 31, 2016.

This graph presents LME spot copper prices and the combined reported stocks of copper at the LME, Commodity Exchange Inc. (COMEX), a division of the New York Mercantile Exchange (NYMEX), and the Shanghai Futures Exchange from January 2007 through September 2017. Beginning in mid-2014, copper prices declined because of concerns about slowing growth rates in China, a stronger U.S. dollar and a broad-based decline in commodity prices, but began to improve in fourth-quarter 2016 and into 2017. During third-quarter2017, LME spot copper prices ranged from a low of $2.62 per pound to a high of $3.13 per pound, averaged $2.88 per pound, and closed at $2.94 per pound on September 30, 2017. The LME spot copper price was $3.09 per pound on October 31, 2017.

We believe the underlying long-term fundamentals of the copper business remain positive, supported by the significant role of copper in the global economy and a challenging long-term supply environment attributable to difficulty in replacing the output of existing large mines with new production sources. Future copper prices are expected to be volatile and are likely to be influenced by demand from China and emerging markets, as well as economic activity in the U.S. and other industrialized countries, the timing of the development of new supplies of copper and the production levels of mines and copper smelters.

This graph presents London PM gold prices from January 2007 through September 2017. An improving economic outlook, stronger U.S. dollar and positive equity performance contributed to lower demand for gold since 2014. During third-quarter2017, London PM gold prices ranged from a low of $1,211 per ounce to a high of $1,346 per ounce, averaged $1,278 per ounce, and closed at $1,283 per ounce on September 30, 2017. The London PM gold price was $1,270 per ounce on October 31, 2017.

This graph presents the Metals Week Molybdenum Dealer Oxide weekly average prices from January 2007 through September 2017. Molybdenum prices declined beginning in mid-2014 because of weaker demand from global steel and stainless steel producers but have rebounded slightly starting in mid-2016. During third-quarter2017, the weekly average price of molybdenum ranged from a low of $7.11 per pound to a high of $8.88 per pound, averaged $8.14 per pound, and was $8.49 per pound on September 30, 2017. The Metals Week Molybdenum Dealer Oxide weekly average price was $8.38 per pound on October 31, 2017.

Revenues

Consolidated revenues totaled $4.3 billion in third-quarter2017 and $11.4 billion for the first nine months of 2017, compared with $3.9 billion in third-quarter2016 and $10.5 billion for the first nine months of 2016. Revenues from our mining operations primarily include the sale of copper concentrate, copper cathode, copper rod, gold in concentrate and molybdenum. Revenues from our oil and gas operations, most of which were sold in 2016, include the sale of oil, natural gas and natural gas liquids (NGLs).

Sales Volumes.Consolidated copper sales decreased to 932 million pounds in third-quarter2017, compared with 1.1 billion pounds in third-quarter2016, primarily reflecting lower ore grades in North America and Indonesia and the timing of shipments. Consolidated copper sales decreased to 2.7 billion pounds for the first nine months of 2017, compared with 3.1 billion pounds for the first nine months of 2016, primarily reflecting lower ore grades in North America and the impact of the May 2016 sale of an additional 13 percent interest in Morenci.

Consolidated gold sales volumes increased to 355 thousand ounces in third-quarter2017 and 969 thousand ounces for the first nine months of 2017, compared with 317 thousand ounces in third-quarter2016 and 674 thousand ounces for the first nine months of 2016, primarily reflecting higher ore grades in Indonesia.

Consolidated molybdenum sales volumes increased to 22 million pounds in third-quarter2017 and 71 million pounds for the first nine months of 2017, compared with 16 million pounds in third-quarter2016 and 52 million pounds for the first nine months of 2016, primarily reflecting higher demand.

Refer to “Operations” for further discussion of sales volumes at our mining operations.

Oil and gas sales volumes of 1.0 MMBOE in third-quarter2017 and 3.8 MMBOE for the first nine months of 2017, were lower than oil and gas sales volumes of 12.0 MMBOE in third-quarter2016 and 36.6 MMBOE for the first nine months of 2016, primarily reflecting the sales of significant oil and gas properties in 2016.

Realized Prices.Our consolidated revenues can vary significantly as a result of fluctuations in the market prices of copper, gold and molybdenum. Third-quarter2017 average realized prices, compared with third-quarter2016, were 34 percent higher for copper, 3 percent lower for gold and 1 percent higher for molybdenum, and average realized prices for the first nine months of 2017, compared with the first nine months of 2016, were 29 percent higher for copper, 2 percent lower for gold and 10 percent higher for molybdenum. Refer to “Markets” for further discussion.

Provisionally Priced Copper Sales.Substantially all of our copper concentrate and cathode sales contracts provide final copper pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted LME monthly average spot copper prices. We receive market prices based on prices in the specified future period, which results in price fluctuations recorded through revenues until the date of settlement. We record revenues and invoice customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on our provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded each reporting period until the date of final pricing. Accordingly, in times of rising copper prices, our revenues benefit from adjustments to the final pricing of provisionally priced sales pursuant to contracts entered into in prior periods; in times of falling copper prices, the opposite occurs. Favorable (unfavorable)

41

impacts of net adjustments to prior periods’ provisionally priced copper sales from continuing operations totaled $95 million in third-quarter2017 and $81 million for the first nine months of 2017, compared with $(15) million in third-quarter2016 and $5 million for the first nine months of 2016, primarily reflecting higher copper prices in the 2017 periods.

At September 30, 2017, we had provisionally priced copper sales at our copper mining operations totaling 338 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $2.93 per pound, subject to final pricing over the next several months. We estimate that each $0.05 change in the price realized from the September 30, 2017, provisional price recorded would have an approximate $11 million effect on our 2017 net income attributable to common stock. The LME spot copper price was $3.09 per pound on October 31, 2017.

Treatment Charges. Revenues from our concentrate sales are recorded net of treatment charges. Lower treatment charges in the 2017 periods, compared with the 2016 periods, primarily reflect lower concentrate sales volumes at North America copper mines.

Purchased Copper.We purchase copper cathode primarily for processing by our Rod & Refining operations. In addition to higher copper prices, we had higher purchased copper volumes in the 2017 periods (75 million pounds in third-quarter2017 and 195 million for the first nine months of 2017, compared with 61 million pounds in third-quarter2016 and 131 million pounds for the first nine months of 2016).

Atlantic Copper Revenues.Atlantic Copper revenues totaled $555 million in third-quarter2017 and $1.4 billion for the first nine months of 2017, compared with $445 million in third-quarter2016 and $1.4 billion for the first nine months of 2016. Higher revenues in third-quarter2017, compared with third-quarter2016, primarily reflect higher copper prices.

Production and Delivery Costs

Consolidated production and delivery costs totaled $2.8 billion in third-quarter2017, $2.5 billion in third-quarter2016, $7.5 billion for the first nine months of 2017 and $8.0 billion for the first nine months of 2016. Production and delivery costs for the third quarter and first nine months of 2017 included charges totaling $216 million at Cerro Verde associated with disputed royalties for prior years (refer to “Operations – South America Mining” for further discussion). Production and delivery costs for the first nine months of 2016 included charges totaling $942 million at oil and gas operations primarily for drillship settlements and inventory adjustments.

Mining Unit Site Production and Delivery Costs. Site production and delivery costs for our copper mining operations primarily include labor, energy and commodity-based inputs, such as sulphuric acid, reagents, liners, tires and explosives. Consolidated unit site production and delivery costs (before net noncash and other costs) for our copper mines averaged $1.57 per pound of copper in third-quarter2017 and $1.60 per pound of copper for the first nine months of 2017, compared with $1.37 per pound of copper in third-quarter2016 and $1.42 per pound of copper for the first nine months of 2016. Higher consolidated unit site production and delivery costs for the 2017 periods, compared with the 2016 periods, primarily reflect lower copper sales volumes. Refer to “Operations – Unit Net Cash Costs” for further discussion of unit net cash costs associated with our operating divisions and to “Product Revenues and Production Costs” for reconciliations of per pound costs by operating division to production and delivery costs applicable to sales reported in our consolidated financial statements.

Depreciation, Depletion and Amortization

Depreciation will vary under the unit-of-production (UOP) method as a result of changes in sales volumes and the related UOP rates at our individual mines. Consolidated depreciation, depletion and amortization (DD&A) totaled $418 million in third-quarter2017 and $1.3 billion for the first nine months of 2017, compared with $643 million in third-quarter2016 and $1.9 billion for the first nine months of 2016. Lower DD&A in the 2017 periods, compared with the 2016 periods, primarily reflects lower DD&A from oil and gas operations resulting from sales of significant oil and gas properties in 2016.

Impairment of Oil and Gas Properties

The review of the carrying value of our oil and gas properties for impairment under full cost accounting rules resulted in the recognition of impairment charges totaling $239 million for third-quarter2016 and $4.3 billion for the first nine months of 2016.

42

Selling, General and Administrative Expenses

Consolidated selling, general and administrative expenses totaled $106 million in third-quarter2017, $110 million in third-quarter2016, $366 million for the first nine months of 2017 and $408 million for the first nine months of 2016. Selling, general and administrative expenses include net oil and gas-related charges totaling $17 million for the first nine months of 2017 for contract termination and $38 million for the first nine months of 2016 for restructuring.

Consolidated selling, general and administrative expenses were net of capitalized general and administrative expenses at our oil and gas operations totaling $16 million in third-quarter2016 and $66 million for the first nine months of 2016.

Mining Exploration and Research Expenses

Consolidated exploration and research expenses for our mining operations totaled $27 million in third-quarter2017, $13 million in third-quarter2016, $61 million for the first nine months of 2017 and $46 million for the first nine months of 2016. Our mining exploration activities are generally associated with our existing mines and focus on opportunities to expand reserves and resources to support development of additional future production capacity. Exploration results continue to indicate opportunities for significant future potential reserve additions in North America and South America. Exploration spending is expected to approximate $75 million for the year 2017.

Environmental Obligations and Shutdown Costs

Environmental obligation costs reflect net revisions to our long-term environmental obligations, which vary from period to period because of changes to environmental laws and regulations, the settlement of environmental matters and/or circumstances affecting our operations that could result in significant changes in our estimates. Shutdown costs include care-and-maintenance costs and any litigation, remediation or related expenditures associated with closed facilities or operations. Net charges (credits) for environmental obligations and shutdown costs totaled $73 million in third-quarter2017, $(3) million in third-quarter2016, $81 million for the first nine months of 2017 and $18 million for the first nine months of 2016. Refer to Note 9 for further discussion.

Net Gain on Sales of Assets

Net gain on sales of assets totaled $33 million in third-quarter2017 and $66 million for the first nine months of 2017, primarily associated with oil and gas transactions. Net gain on sales of assets totaled $13 million in third-quarter2016 and $762 million for the first nine months of 2016, primarily associated with the sales of a 13 percent undivided interest in the Morenci unincorporated joint venture and a portion of our interest in the Timok exploration project in Serbia.

Interest Expense, Net

Interest expense, net, for the third quarter and first nine months of 2017 includes $141 million associated with disputed Cerro Verde royalties (refer to Note 9 for additional discussion). Consolidated interest costs (before capitalization and excluding interest expense associated with disputed Cerro Verde royalties) totaled $196 million in third-quarter2017, $211 million in third-quarter2016, $583 million for the first nine months of 2017 and $647 million for the first nine months of 2016. Lower interest cost for the 2017 periods, compared to the 2016 periods, reflects a decrease in total debt .

Capitalized interest varies with the level of expenditures for our development projects and average interest rates on our borrowings and totaled $33 million in third-quarter2017, $24 million in third-quarter2016, $91 million for the first nine months of 2017 and $73 million for the first nine months of 2016.

Income Taxes

Following is a summary of the approximate amounts used in the calculation of our consolidated income tax provision from continuing operations for the 2017 and 2016 periods (in millions, except percentages):

	Nine Months Ended September 30,
	2017									2016
	Income (Loss)a			Effective Tax Rate		Income Tax Benefit (Provision)				Income (Loss)a			Effective Tax Rate	Income Tax Benefit (Provision)

Consolidated FCX	$	1,577		47%	g	$	(747	)		$	(3,964	)	(2)%	$	(79	)

a. Represents income (loss) from continuing operations by geographic location before income taxes and equity in affiliated companies’ net earnings.

b. Includes net tax credits of $21 million associated with alternative minimum tax credit carryforwards.

c. Includes net tax credits of $290 million associated with alternative minimum tax credits, changes to valuation allowances and net operating loss carryback claims.

d. Includes tax charges of $127 million for disputed royalties and other related mining taxes for the period October 2011 through the year 2013 (when royalties were determined based on operating income), mostly offset by a tax benefit of $125 million associated with disputed royalties and other related mining taxes for the period December 2006 through the year 2013.

e. As a result of the impairment to U.S. oil and gas properties, we recorded tax charges to establish valuation allowances against U.S. federal and state deferred tax assets that will not generate a future benefit.

f. In accordance with applicable accounting rules, we adjust our interim provision for income taxes to equal our consolidated tax rate.

g. The consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which we operate. Accordingly, variations in the relative proportions of jurisdictional income result in fluctuations to our consolidated effective income tax rate. Assuming achievement of current sales volume and cost estimates and average prices of $3.00 per pound for copper, $1,300 per ounce for gold and $8.00 per pound for molybdenum for fourth-quarter2017, we estimate our consolidated effective tax rate related to continuing operations for the year 2017 will approximate 45 percent and would decrease with higher prices.

Net Income (Loss) from Discontinued Operations

In November 2016, we completed the sale of our interest in TFHL, through which we had an effective 56 percent interest in the Tenke copper and cobalt concessions in the Democratic Republic of Congo. In accordance with accounting guidelines, the results of TFHL have been reported as discontinued operations for all periods presented. Net income from discontinued operations totaled $3 million in third-quarter2017 and $50 million for the first nine months of 2017, which primarily reflected adjustments to the fair value of the potential $120 million contingent consideration related to the sale, which totaled $58 million at September 30, 2017, and will continue to be adjusted through December 31, 2019. Net loss from discontinued operations of $6 million in third-quarter2016 and $191 million for the first nine months of 2016 include an estimated loss on disposal of $5 million for third-quarter2016 and $182 million for the first nine months of 2016. Refer to Note 2 for a summary of the components of net income (loss) from discontinued operations.

OPERATIONS

North America Copper Mines

We operate seven open-pit copper mines in North America – Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. All of the North America mining operations are wholly owned, except for Morenci.

We record our undivided joint venture interest in Morenci using the proportionate consolidation method. On May 31, 2016, we completed the sale of an additional 13 percent undivided interest in Morenci. As a result of the transaction, our undivided interest in Morenci was prospectively reduced from 85 percent to 72 percent.

44

The North America copper mines include open-pit mining, sulfide ore concentrating, leaching and solution extraction/electrowinning (SX/EW) operations. A majority of the copper produced at our North America copper mines is cast into copper rod by our Rod & Refining segment. The remainder of our North America copper sales is in the form of copper cathode or copper concentrate, a portion of which is shipped to Atlantic Copper (our wholly owned smelter). Molybdenum concentrate, gold and silver are also produced by certain of our North America copper mines.

Operating and Development Activities. We have significant undeveloped reserves and resources in North America and a portfolio of potential long-term development projects. Future investments will be undertaken based on the results of economic and technical feasibility studies, and are dependent on market conditions. We continue to study opportunities to reduce the capital intensity of our long-term development projects.

Through exploration drilling, we have identified a significant resource at our wholly owned Lone Star project located near the Safford operation in eastern Arizona. The Safford mine is expected to have copper production through 2024. Initial production from the Lone Star oxide ores could begin in 2021 assuming an approximate three-year development period and using existing infrastructure at the adjacent Safford operation. Total preliminary capital cost estimates for development, including mine equipment and pre-production stripping, approximates $850 million. Projected production from the Lone Star oxide ores would average approximately 200 million pounds of copper per year with an approximate 20-year mine life. Considering the long-term nature and size of the project, results could vary from these estimates. The project would also advance the potential for development of a larger-scale district opportunity. We have obtained regulatory approvals for this project and are assessing the timing to commence pre-stripping activities. We are conducting additional drilling as we continue to evaluate longer term opportunities available from the significant sulfide potential in the Lone Star/Safford minerals district. 

Operating Data. Following is a summary of consolidated operating data for the North America copper mines for the third quarters and first nine months of2017 and 2016:

a. Refer to “Consolidated Results” for our consolidated molybdenum sales volumes, which include sales of molybdenum produced at the North America copper mines.

45

North America’s consolidated copper sales volumes of 347 million pounds in third-quarter2017 and 1.1 billion pounds for the first nine months of 2017 were lower than third-quarter2016 sales of 458 million pounds and 1.4 billion pounds for the first nine months of 2016, primarily reflecting lower ore grades. Additionally, third-quarter2017 was impacted by the timing of shipments.

North America copper sales are estimated to approximate 1.5 billion pounds for the year 2017, compared with 1.8 billion pounds in 2016.

Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.

Gross Profit per Pound of Copper and Molybdenum

The following table summarizes unit net cash costs and gross profit per pound at our North America copper mines for the third quarters and first nine months of2017 and 2016. Refer to “Product Revenues and Production Costs” for an explanation of the “by-product” and “co-product” methods and a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in our consolidated financial statements.

a. Reflects sales of molybdenum produced by certain of the North America copper mines to our molybdenum sales company at market-based pricing.

b. Includes $21 million ($0.02 per pound of copper) for asset impairment charges at Morenci.

Our North America copper mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.61 per pound of copper in third-quarter2017 and $1.54 per pound for the first nine months of 2017 were higher than unit net cash costs of $1.37 per pound in third-quarter2016 and $1.40 per pound for the first nine months of 2016, primarily reflecting lower sales volumes.

Because certain assets are depreciated on a straight-line basis, North America’s average unit depreciation rate may vary with asset additions and the level of copper production and sales.

Average unit net cash costs (net of by-product credits) for our North America copper mines are expected to approximate $1.58 per pound of copper for the year 2017, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $8.00 per pound for fourth-quarter2017. North America’s average unit net cash costs for the year 2017 would change by approximately $0.007 per pound for each $2 per pound change in the average price of molybdenum.

South America Mining

We operate two copper mines in South America – Cerro Verde in Peru (in which we own a 53.56 percent interest) and El Abra in Chile (in which we own a 51 percent interest). These operations are consolidated in our financial statements.

South America mining includes open-pit mining, sulfide ore concentrating, leaching and SX/EW operations. Production from our South America mines is sold as copper concentrate or cathode under long-term contracts. Our South America mines also sell a portion of their copper concentrate production to Atlantic Copper. In addition to copper, the Cerro Verde mine produces molybdenum concentrate and silver.

Cerro Verde Royalty Dispute.In October 2017, the Peruvian Supreme Court issued a ruling in favor of SUNAT, Peru’s national tax authority, that the assessments of royalties for the year 2008 on ore processed by the Cerro Verde concentrator were proper under Peruvian law.  As previously reported in our annual report on Form 10-K for the year ended December 31, 2016, SUNAT has assessed mining royalties on ore processed by the Cerro Verde concentrator for the period December 2006 to September 2011, which Cerro Verde has contested on the basis that its 1998 stability agreement exempts from royalties all minerals extracted from its mining concessions, irrespective of the method used for processing those minerals. 

47

As a result of the unfavorable Peruvian Supreme Court decision on the 2008 royalty dispute, Cerro Verde recorded pre-tax charges totaling $357 million ($359 million including net tax charges and $188 million net of noncontrolling interests) in third-quarter 2017 associated with prior assessments and potential royalty and related assessments for December 2006 through the year 2013. Effective January 1, 2014, Cerro Verde entered into a new 15-year stability agreement and has been paying royalties in accordance with the new stability agreement.

Cerro Verde acted in good faith in applying the provisions of its 1998 stability agreement and continues to evaluate alternatives to defend its rights. Cerro Verde intends to seek a waiver available under Peruvian law of penalties and interest associated with this dispute and has not recorded charges for potential unpaid penalties and interest totaling $360 million ($193 million net of noncontrolling interests) at September 30, 2017, as we believe that Cerro Verde should be successful under Peruvian law in obtaining a waiver. Refer to Note 9 for additional discussion.

Operating and Development Activities. The Cerro Verde expansion project commenced operations in September 2015 and achieved capacity operating rates during first-quarter 2016. Cerro Verde’s expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. The project expanded the concentrator facilities from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day.

We continue to evaluate a major expansion at El Abra to process additional sulfide material and to achieve higher recoveries. Exploration results at El Abra indicate a significant sulfide resource, which could potentially support a major mill project similar to facilities recently constructed at Cerro Verde. Future investments will depend on technical studies, which are being advanced, economic factors and market conditions.

Operating Data. Following is a summary of consolidated operating data for our South America mining operations for the third quarters and first nine months of2017 and 2016:

	Three Months Ended September 30,				Nine Months Ended September 30,

a. Refer to “Consolidated Results” for our consolidated molybdenum sales volumes, which include sales of molybdenum produced at Cerro Verde.

South America’s consolidated copper sales volumes of 327 million pounds in third-quarter2017 approximated third-quarter2016 sales of 323 million pounds. South America’s lower consolidated copper sales volumes of 923 million pounds for the first nine months of 2017, compared with 973 million pounds for the first nine months of 2016, reflect the Cerro Verde operation being unfavorably impacted by unusually high rainfall and a 21-day labor strike during first-quarter 2017.

Copper sales from South America mines are expected to approximate 1.2 billion pounds of copper for the year 2017, compared with 1.3 billion pounds of copper in 2016.

49

Our South America mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. Average unit net cash costs (net of by-product credits) of $1.64 per pound of copper in third-quarter2017 and $1.61 per pound for the first nine months of 2017 were higher than unit net cash costs of $1.40 per pound in third-quarter2016 and $1.37 per pound for the first nine months of 2016, primarily reflecting higher mining, milling and employee costs at Cerro Verde.

Revenues from Cerro Verde’s concentrate sales are recorded net of treatment charges. Accordingly, treatment charges will vary with Cerro Verde’s sales volumes and the price of copper.

Because certain assets are depreciated on a straight-line basis, South America’s unit depreciation rate may vary with asset additions and the level of copper production and sales.

Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to “Consolidated Results – Revenues” for further discussion of adjustments to prior period provisionally priced copper sales.

Average unit net cash costs (net of by-product credits) for our South America mining operations are expected to approximate $1.64 per pound of copper for the year 2017, based on current sales volume and cost estimates and assuming an average price of $8.00 per pound of molybdenum for fourth-quarter2017.

Indonesia Mining

Indonesia mining includes PT-FI’s Grasberg minerals district, one of the world’s largest copper and gold deposits, in Papua, Indonesia. We own 90.64 percent of PT-FI, including 9.36 percent owned through our wholly owned subsidiary, PT Indocopper Investama.

PT-FI proportionately consolidates an unincorporated joint venture with Rio Tinto plc (Rio Tinto), under which Rio Tinto has a 40 percent interest in certain assets and a 40 percent interest through 2022 in production exceeding specified annual amounts of copper, gold and silver. Refer to Note 3 in our annual report on Form 10-K for the year ended December 31, 2016, for discussion of our joint venture with Rio Tinto.

PT-FI produces copper concentrate that contains significant quantities of gold and silver. Substantially all of PT-FI’s copper concentrate is sold under long-term contracts, and during the first nine months of 2017, approximately half of PT-FI’s concentrate production was sold to PT Smelting, its 25-percent-owned smelter and refinery in Gresik, Indonesia.

Regulatory Matters. In January and February 2017, the Indonesian government issued new regulations to address the export of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. The new regulations permit the continuation of copper concentrate exports for a five-year period through January 2022, subject to various conditions, including conversion from a contract of work to a special operating license (known as an IUPK, which does not provide the same level of fiscal and legal protections as PT-FI’s Contract of Work (COW), which remains in effect), a commitment to the completion of smelter construction in five years and payment of export duties to be determined by the Ministry of Finance. In addition, the new regulations enable application for an extension of operating rights five years before expiration of the IUPK and require foreign IUPK holders to divest a 51 percent interest in the licensed entity to Indonesian interests no later than the tenth year of production. Export licenses would be valid for one-year periods, subject to review every six months, depending on smelter construction progress.

Following the issuance of the January and February 2017 regulations and discussions with the Indonesian government, PT-FI advised the government that it was prepared to convert its COW to an IUPK, subject to obtaining an investment stability agreement providing contractual rights with the same level of legal and fiscal certainty enumerated under its COW, and provided that the COW would remain in effect until it is replaced by a mutually satisfactory alternative. PT-FI also committed to commence construction of a new smelter during a five-year timeframe, following approval of the extension of its long-term operating rights.

On January 12, 2017, PT-FI suspended exports in response to Indonesian regulations adopted in January 2014. In addition, as a result of labor disturbances and a delay in the renewal of its export license for anode slimes, PT Smelting’s operations were shut down from January 19, 2017, until early March 2017. On February 10, 2017, PT-FI was forced to suspend production as a result of limited storage capacity at PT-FI and PT Smelting. On April 21,

50

2017, the Indonesian government issued a permit to PT-FI that allowed exports to resume for a six-month period, and PT-FI commenced export shipments.

In mid-February 2017, pursuant to the COW’s dispute resolution process, PT-FI provided formal notice to the Indonesian government of an impending dispute listing the government’s breaches and violations of the COW. PT-FI continues to reserve its rights under these provisions.

As a result of the 2017 regulatory restrictions and uncertainties regarding long-term investment stability, PT-FI took actions to adjust its cost structure, slow investments in its underground development projects and new smelter, and place certain of its workforce on furlough programs.

In late March 2017, the Indonesian government amended the regulations to enable PT-FI to retain its COW until replaced with an IUPK accompanied by an investment stability agreement, and to grant PT-FI a temporary IUPK through October 10, 2017, that would allow concentrate exports to resume during this period. In April 2017, PT-FI entered into a Memorandum of Understanding with the Indonesian government confirming that the COW would continue to be valid and honored until replaced by a mutually agreed IUPK and investment stability agreement. PT-FI agreed to continue to pay a five percent export duty during this period.

In August 2017, we reached an understanding with the Indonesian government on a framework that would resolve PT-FI’s long-term operating rights. This framework includes (i) conversion from the COW to an IUPK providing PT-FI with long-term operating rights through 2041, (ii) Indonesian government certainty of fiscal and legal terms during the term of the IUPK, (iii) PT-FI commitment to construct a new smelter in Indonesia within five years of reaching a definitive agreement, and (iv) divestment of 51 percent of the project area interests to Indonesian participants at fair market value structured so that we retain control over operations and governance of PT-FI.

The framework requires documentation and execution of a definitive agreement, which must be approved by our Board and joint venture partner Rio Tinto. The parties continue to negotiate to reach agreement on important aspects of implementation of the framework, including the timing and process of divestment, governance matters, and the determination of fair market value, and to complete documentation on a comprehensive agreement for PT-FI’s extended operations through 2041. The parties have expressed a mutual objective of completing the negotiations and documentation during 2017.

In October 2017, the Indonesian government extended PT-FI’s export rights to December 31, 2017, while negotiations to reach and document a comprehensive long-term definitive agreement based on the agreed framework continue. Until a definitive agreement is reached, PT-FI has reserved all rights under its COW, including pursuing arbitration under the dispute resolution provisions.

We cannot predict whether PT-FI will be successful in reaching a satisfactory definitive agreement on the terms of its long-term mining rights. Refer to “Risk Factors” contained in Part I, Item 1A. of our annual report on Form 10-K for the year ended December 31, 2016, for further discussion of risks associated with our operations in Indonesia.

Operating and Development Activities. PT-FI is currently mining the final phase of the Grasberg open pit, which contains high copper and gold ore grades. PT-FI expects to mine high-grade ore over the next several quarters prior to transitioning to the Grasberg Block Cave underground mine in early 2019.

PT-FI has several projects in the Grasberg minerals district related to the development of its large-scale, long-lived, high-grade underground ore bodies. In aggregate, these underground ore bodies are expected to produce large-scale quantities of copper and gold following the transition from the Grasberg open pit. Assuming a definitive agreement is reached to support PT-FI’s long-term investment plans, estimated annual capital spending on these projects would average $1.0 billion per year ($0.8 billion per year net to PT-FI) over the next five years. Considering the long-term nature and size of these projects, actual costs could vary from these estimates. In response to market conditions and Indonesian regulatory uncertainty, timing of these expenditures continues to be reviewed. If PT-FI is unable to reach a definitive agreement with the Indonesian government on its long-term mining rights, we intend to reduce or defer investments significantly in our underground development projects and pursue arbitration under PT-FI’s COW.

The following provides additional information on the continued development of the Common Infrastructure project, the Grasberg Block Cave underground mine and the Deep Mill Level Zone (DMLZ) ore body that lies below the

51

Deep Ore Zone (DOZ) underground mine. Our current plans and mineral reserves in Indonesia assume that PT-FI’s long-term mining rights will be extended through 2041, as stated in the COW.

Common Infrastructure and Grasberg Block Cave Mine. In 2004, PT-FI commenced its Common Infrastructure project to provide access to its large undeveloped underground ore bodies located in the Grasberg minerals district through a tunnel system located approximately 400 meters deeper than its existing underground tunnel system. In addition to providing access to our underground ore bodies, the tunnel system will enable PT-FI to conduct future exploration in prospective areas associated with currently identified ore bodies. The tunnel system was completed to the Big Gossan terminal, and the Big Gossan mine was brought into production in 2010. The Big Gossan underground mine is currently preparing to restart production. Development of the DMLZ and Grasberg Block Cave underground mines is advancing using the Common Infrastructure project tunnels as access.

The Grasberg Block Cave underground mine accounts for approximately half of our recoverable proven and probable reserves in Indonesia. Production from the Grasberg Block Cave underground mine is expected to commence in early 2019, following the end of mining of the Grasberg open pit. Targeted production rates once the Grasberg Block Cave mining operation reaches full capacity are expected to approximate 130,000-160,000 metric tons of ore per day. PT-FI is reviewing its operating plans to determine the optimum mine plan for the Grasberg Block Cave underground mine.

Aggregate mine development capital for the Grasberg Block Cave underground mine and associated Common Infrastructure is expected to approximate $6.3 billion (incurred between 2008 and 2022), with PT-FI’s share totaling approximately $5.8 billion. Aggregate project costs totaling $3.2 billion have been incurred through September 30, 2017, including $118 million during third-quarter2017. As a result of regulatory uncertainty, PT-FI has slowed investments in its underground development projects. If PT-FI is unable to reach a definitive agreement with the Indonesian government on its long-term mining rights, we intend to reduce or defer investments significantly in our underground development projects and pursue arbitration under PT-FI’s COW.

DMLZ. The DMLZ ore body lies below the DOZ mine at the 2,590-meter elevation and represents the downward continuation of mineralization in the Ertsberg East Skarn system and neighboring Ertsberg porphyry. In September 2015, PT-FI initiated pre-commercial production that represents ore extracted during the development phase for the purpose of obtaining access to the ore body. In June 2017, production from the DMLZ underground mine was impacted by mining-induced seismic activity, which is not uncommon in block cave mining. To mitigate the impact of these events, PT-FI implemented a revised mine sequence and start-up plan in third-quarter2017. PT-FI expects DMLZ to ramp up to full capacity of 80,000 metric tons of ore per day in 2021, but at a slower pace than previous estimates.

Drilling efforts continue to determine the extent of the ore body. Aggregate mine development capital costs for the DMLZ underground mine are expected to approximate $3.2 billion (incurred between 2009 and 2021), with PT-FI’s share totaling approximately $1.9 billion. Aggregate project costs totaling $2.1 billion have been incurred through September 30, 2017, including $62 million during third-quarter2017. As a result of regulatory uncertainty, PT-FI has slowed investments in its underground development projects. If PT-FI is unable to reach a definitive agreement with the Indonesian government on its long-term mining rights, we intend to reduce or defer investments significantly in our underground development projects and pursue arbitration under PT-FI’s COW.

Other Matters. In late October 2017, Indonesia’s Ministry of Environment and Forestry (the Ministry) notified PT-FI of administrative sanctions related to certain activities the Ministry indicated are not reflected in its environmental permit. The Ministry also notified PT-FI that certain operational activities were inconsistent with factors set forth in its environmental permitting studies and that additional monitoring and improvements need to be undertaken related to air quality, water drainage, treatment and handling of certain wastes, and tailings management. PT-FI has been engaged in a process to update its permits through submissions and dialogue with the Ministry, which began in late 2014. PT-FI believes that it has submitted the required documentation to update its permits, and is in the process of addressing other points raised by the Ministry.

As further discussed in “Risk Factors” contained in Part I. Item 1A of our annual report on Form 10-K for the year ended December 31, 2016, in 2009, there were a series of shooting incidents within the PT-FI project area, with sporadic shooting incidents continuing through January 1, 2015. From August 2017 through November 3, 2017, there were six shooting incidents within the PT-FI project area and five shooting incidents in nearby areas, which resulted in one fatality and 12 injuries. The safety of our workforce is a critical concern, and PT-FI is working

52

cooperatively with the Indonesian government to address security issues. We also continue to limit the use of the road leading to our mining and milling operations to secured convoys.

Operating Data. Following is a summary of consolidated operating data for our Indonesia mining operations for the third quarters and first nine months of2017 and 2016:

a. Amounts represent the approximate average daily throughput processed at PT-FI’s mill facilities from each producing mine and from development activities that result in metal production.

b. Ore milled from the DOZ underground mine is expected to ramp up to 60,000 metric tons of ore per day in 2018.

Indonesia mining’s consolidated copper sales volumes of 258 million pounds in third-quarter2017 were lower than sales of 332 million pounds in third-quarter2016, primarily reflecting lower copper ore grades and timing of shipments. Indonesia mining’s consolidated copper sales volumes of 630 million pounds for the first nine months of 2017 were lower than sales of 702 million pounds for the first nine months of 2016, primarily reflecting the impact of regulatory restrictions on PT-FI’s concentrate exports at the beginning of 2017 (see discussion above in “Regulatory Matters”).

Indonesia’s consolidated gold sales of 352 thousand ounces in third-quarter2017 and 956 thousand ounces for the first nine months of 2017 were higher than sales of 307 thousand ounces in third-quarter2016 and 653 thousand ounces for the first nine months of 2016, primarily reflecting higher gold ore grades, partly offset by timing of shipments.

During third-quarter 2017, PT-FI's labor productivity improved significantly following a recovery from disruptions that occurred in the first half of the year. Mining and milling rates improved throughout the quarter, and PT-FI continues to assess opportunities to advance mining of a section of high-grade material during 2018 and 2019 through open-pit mining rather than over time through the Grasberg Block Cave underground mine.

53

In October 2017, PT-FI and union officials commenced discussions for a new two-year labor agreement. The existing agreement will continue in effect until a new agreement is consummated.

Assuming achieving planned operating rates for fourth-quarter 2017, consolidated sales volumes from Indonesia mining are expected to approximate 1.0 billion pounds of copper and 1.6 million ounces of gold for the year 2017, compared with 1.1 billion pounds of copper and 1.1 million ounces of gold for the year 2016. At the Grasberg mine, the sequencing of mining areas with varying ore grades causes fluctuations in quarterly and annual production of copper and gold.

Indonesia mining’s projected sales volumes for the year 2017 are dependent on a number of factors, including operational performance, workforce productivity and the timing of shipments.

Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.

Gross Profit per Pound of Copper and per Ounce of Gold

The following table summarizes the unit net cash costs and gross profit per pound of copper and per ounce of gold at our Indonesia mining operations for the third quarters and first nine months of2017 and 2016. Refer to “Product Revenues and Production Costs” for an explanation of “by-product” and “co-product” methods and a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in our consolidated financial statements.

a. Includes costs charged directly to production and delivery costs totaling $9 million ($0.03 per pound of copper) for third-quarter 2017 and $112 million ($0.18 per pound of copper) for the first nine months of 2017 as a result of workforce reductions.

b. Includes asset retirement charges of $17 million ($0.05 per pound of copper in third-quarter2016 and $0.02 per pound of copper for the first nine months of2016).

A significant portion of PT-FI’s costs are fixed and unit costs vary depending on production volumes and other factors. Indonesia’s unit net cash costs (including gold and silver credits) of $0.13 per pound of copper in third-quarter2017 and $0.26 per pound of copper for the first nine months of 2017 were lower than unit net cash costs of $0.57 per pound of copper in third-quarter2016 and $0.92 per pound of copper for the first nine months of 2016, primarily reflecting higher gold and silver credits, partly offset by lower copper sales volumes.

Treatment charges vary with the volume of metals sold and the price of copper, and royalties vary with the volume of metals sold and the prices of copper and gold.

PT-FI’s royalties totaled $43 million in third-quarter2017, $40 million in third-quarter2016, $106 million for the first nine months of 2017 and $84 million for the first nine months of 2016. Export duties totaled $21 million in third-quarter2017, $34 million in third-quarter2016, $62 million for the first nine months of 2017 and $63 million for the first nine months of 2016. As further discussed above in “Regulatory Matters,” PT-FI agreed to continue to pay a five percent export duty.

Higher depreciation rates for the 2017 periods, compared with the 2016 periods, primarily relate to higher amortization of asset retirement costs associated with revised estimates at the end of 2016 for an overburden stockpile. Additionally, because certain assets are depreciated on a straight-line basis, PT-FI’s unit depreciation rate varies with the level of copper production and sales.

Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to “Consolidated Results – Revenues” for further discussion of adjustments to prior period provisionally priced copper sales.

PT Smelting intercompany loss represents the change in the deferral of 25 percent of PT-FI’s profit on sales to PT Smelting. Refer to “Operations – Smelting & Refining” for further discussion.

Assuming an average gold price of $1,300 per ounce for fourth-quarter 2017 and achievement of current sales volume and cost estimates, unit net cash costs (net of gold and silver credits) for Indonesia mining are expected to approximate $0.07 per pound of copper for the year 2017. Indonesia mining’s unit net cash costs for the year 2017 would change by approximately $0.04 per pound for each $50 per ounce change in the average price of gold.

55

Because of the fixed nature of a large portion of Indonesia’s costs, unit costs vary from quarter to quarter depending on copper and gold volumes.

Molybdenum Mines

We have two wholly owned molybdenum mines in North America – the Henderson underground mine and the Climax open-pit mine, both in Colorado. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of the molybdenum concentrate produced at the Henderson and Climax mines, as well as from our North America and South America copper mines, is processed at our own conversion facilities.

Operating and Development Activities. In response to market conditions, the Henderson molybdenum mine continues to operate at reduced rates. Production from the Molybdenum mines totaled 8 million pounds of molybdenum in third-quarter2017, 5 million pounds in third-quarter2016, 24 million pounds for the first nine months of 2017 and 19 million pounds for the first nine months of 2016. Refer to “Consolidated Results” for our consolidated molybdenum operating data, which includes sales of molybdenum produced at our Molybdenum mines, and from our North America and South America copper mines, and refer to “Outlook” for projected consolidated molybdenum sales volumes.

Unit Net Cash Costs Per Pound of Molybdenum. Unit net cash costs per pound of molybdenum is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.

Average unit net cash costs for our Molybdenum mines of $7.90 per pound of molybdenum in third-quarter2017 and $7.60 per pound of molybdenum for the first nine months of 2017 were lower than average unit net cash costs of $10.28 per pound of molybdenum in third-quarter2016 and $8.39 per pound of molybdenum for the first nine months of 2016, primarily reflecting higher volumes. Assuming achievement of current sales volume and cost estimates, we estimate unit net cash costs for the Molybdenum mines are expected to average $7.85 per pound of molybdenum for the year 2017. Refer to “Product Revenues and Production Costs” for a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in our consolidated financial statements.

Smelting and Refining

We wholly own and operate a smelter in Arizona (Miami smelter) and a smelter and refinery in Spain (Atlantic Copper). Additionally, PT-FI owns 25 percent of a smelter and refinery in Gresik, Indonesia (PT Smelting). Treatment charges for smelting and refining copper concentrate consist of a base rate per pound of copper and per ounce of gold and are generally fixed. Treatment charges represent a cost to our mining operations and income to Atlantic Copper and PT Smelting. Thus, higher treatment charges benefit our smelter operations and adversely affect our mining operations. Our North America copper mines are less significantly affected by changes in treatment charges because these operations are largely integrated with our Miami smelter. Through this form of downstream integration, we are assured placement of a significant portion of our concentrate production.

Atlantic Copper smelts and refines copper concentrate and markets refined copper and precious metals in slimes. During the first nine months of 2017, Atlantic Copper’s concentrate purchases from our copper mining operations included 16 percent from our North America copper mines and 10 percent from South America mining, with the remainder purchased from third parties.

In March 2017, PT Smelting’s anode slimes export license was renewed through March 1, 2018. PT-FI’s contract with PT Smelting provides for PT-FI to supply 100 percent of the copper concentrate requirements (subject to a minimum or maximum rate) necessary for PT Smelting to produce 205,000 metric tons of copper annually on a priority basis. PT-FI may also sell copper concentrate to PT Smelting at market rates for quantities in excess of 205,000 metric tons of copper annually. During the first nine months of 2017, PT-FI supplied substantially all of PT Smelting’s concentrate requirements. Minimum and maximum treatment charge rates have been approved through April 2020.

56

We defer recognizing profits on sales from our mining operations to Atlantic Copper and on 25 percent of PT-FI’s sales to PT Smelting until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net additions to net income attributable to common stock of $24 million in third-quarter2017, $17 million for third-quarter2016, less than $1 million for the first nine months of 2017 and $6 million for the first nine months of 2016. Our net deferred profits on our inventories at Atlantic Copper and PT Smelting to be recognized in future periods’ net income attributable to common stock totaled $62 million at September 30, 2017. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in our net deferred profits and quarterly earnings.

CAPITAL RESOURCES AND LIQUIDITY

Our consolidated operating cash flows vary with sales volumes, prices realized from copper, gold and molybdenum sales, production costs, income taxes, other working capital changes and other factors. We believe that we have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. We are pursuing opportunities to enhance our mines’ net present values, and we continue to advance studies for future development of our copper resources, the timing of which will be dependent on market conditions.

Cash

Following is a summary of the U.S. and international components of consolidated cash and cash equivalents available to the parent company, net of noncontrolling interests’ share, taxes and other costs at September 30, 2017 (in billions):

Cash at domestic companies	$	3.7
Cash at international operations	1.3
Total consolidated cash and cash equivalents	5.0
Noncontrolling interests’ share	(0.4		)
Cash, net of noncontrolling interests’ share	4.6
Withholding taxes and other	(0.1		)
Net cash available	$	4.5

Cash held at our international operations is generally used to support our foreign operations’ capital expenditures, operating expenses, working capital and other tax payments, or other cash needs. Management believes that

sufficient liquidity is available in the U.S. from cash balances and availability from our revolving credit facility. We have not elected to permanently reinvest earnings from our foreign subsidiaries, and we have recorded deferred tax liabilities for foreign earnings that are available to be repatriated to the U.S. From time to time, our foreign subsidiaries distribute earnings to the U.S. through dividends that are subject to applicable withholding taxes and noncontrolling interests’ share.

Debt

Following is a summary of our total debt and the related weighted-average interest rates at September 30, 2017 (in billions, except percentages):

			Weighted-
			Average
			Interest Rate
Senior Notes	$	13.3	4.4%
Cerro Verde credit facility	1.5		3.1%
Total debt	$	14.8	4.2%

In September 2017, we redeemed $543 million aggregate principal amount of senior notes, resulting in annual cash interest savings of approximately $35 million. We recognized an $11 million gain on early extinguishment of debt in connection with the redemptions. During the first nine months of 2017, we have reduced our total debt balance by $1.25 billion. Maturities of debt at September 30, 2017, total $0.7 billion in fourth-quarter 2017, $1.5 billion in 2018, $1.9 billion in 2020, $1.3 billion in 2021 and $9.4 billion thereafter.

At September 30, 2017, we had no borrowings, $36 million in letters of credit issued and availability of $3.5 billion under our revolving credit facility, which matures on May 31, 2019.

Refer to Note 6 for further discussion of debt.

Operating Activities

We generated consolidated operating cash flows of $3.0 billion (including $0.4 billion in working capital sources and changes in tax payments) for the first nine months of 2017 and $2.6 billion (including $0.5 billion in working capital sources and changes in tax payments) for the first nine months of 2016.

Subject to future commodity prices for copper, gold and molybdenum, we expect estimated consolidated operating cash flows for the years 2017 and 2018, plus available cash and availability under our credit facility and uncommitted lines of credit, to be sufficient to fund our budgeted capital expenditures, scheduled debt maturities, noncontrolling interest distributions and other cash requirements for the year. Refer to “Outlook” for further discussion of projected operating cash flows for the year 2017, and to “Risk Factors,” contained in Part I, Item 1A. of our annual report on Form 10-K for the year ended December 31, 2016, for discussion of regulatory matters in Indonesia, which could have a significant impact on future results.

Investing Activities

Capital Expenditures. Capital expenditures, including capitalized interest, totaled $1.0 billion for the first nine months of 2017, including $0.6 billion for major mining projects. Capital expenditures, including capitalized interest, totaled $2.3 billion for the first nine months of 2016, consisting of $1.2 billion for mining operations (including approximately $0.9 billion for major projects) and $1.1 billion for oil and gas operations.

Lower capital expenditures for the first nine months of 2017, compared with the first nine months of 2016, primarily reflect a decrease in oil and gas activities as a result of the sales of significant oil and gas properties in 2016 and a decrease in major mining projects associated with the completion of the Cerro Verde expansion. Refer to “Outlook” for further discussion of projected capital expenditures for the year 2017.

Dispositions. Net proceeds from asset sales totaled $1.4 billion for the first nine months of 2016 primarily associated with the $1.0 billion sale of an additional 13 percent undivided interest in Morenci, the sale of an interest in the Timok exploration project in Serbia and from oil and gas asset sales, including the Haynesville shale assets and certain oil and gas royalty interests. Refer to Note 2 for further discussion of these transactions.

Financing Activities

Debt Transactions. Net repayments of debt for the first nine months of 2017 totaled $1.2 billion primarily for the redemption and repayment of senior notes and the repayment of Cerro Verde’s shareholder loans, partly offset by the additional borrowings on Cerro Verde’s credit facility.

Net repayments of debt for the first nine months of 2016 totaled $1.1 billion, primarily reflecting payments of $0.6 billion on our term loan, $0.2 billion on the Cerro Verde credit facility and $0.2 billion on lines of credit.

Dividends. The Board suspended our annual common stock dividend in December 2015. The declaration of dividends is at the discretion of our Board and will depend upon our financial results, cash requirements, future prospects and other factors deemed relevant by our Board.

Common stock dividends of $2 million for the first nine months of 2017 and $5 million for the first nine months of 2016 related to accumulated dividends paid for vested stock-based compensation.

Cash dividends paid to noncontrolling interests totaled $67 million for the first nine months of2017 and $87 million for the first nine months of2016. These payments will vary based on the operating results and cash requirements of our consolidated subsidiaries.

CONTRACTUAL OBLIGATIONS

As further discussed in Note 6, during the first nine months of 2017, we have reduced our December 31, 2016, total debt balance by $1.25 billion. There have been no other material changes in our contractual obligations since December 31, 2016. Refer to Part II, Items 7. and 7A. in our annual report on Form 10-K for the year ended December 31, 2016, for information regarding our contractual obligations.

58

CONTINGENCIES

Environmental and Asset Retirement Obligations

Our current and historical operating activities are subject to stringent laws and regulations governing the protection of the environment. We perform a comprehensive annual review of our environmental and asset retirement obligations and also review changes in facts and circumstances associated with these obligations at least quarterly. Other than as disclosed in Note 9, there have been no material changes to our environmental and asset retirement obligations since December 31, 2016. Updated cost assumptions, including increases and decreases to cost estimates, changes in the anticipated scope and timing of remediation activities, and settlement of environmental matters may result in additional revisions to certain of our environmental obligations. Refer to Note 12 in our annual report on Form 10-K for the year ended December 31, 2016, for further information regarding our environmental and asset retirement obligations.

Litigation and Other Contingencies

Other than as discussed in Note 9, there have been no material changes to our contingencies associated with legal proceedings and other matters since December 31, 2016. Refer to Note 12 and “Legal Proceedings” contained in Part I, Item 3. of our annual report on Form 10-K for the year ended December 31, 2016, as updated in Note 9 in our quarterly reports on Form 10-Q for the quarters ended March 31, 2017, and June 30, 2017, for further information regarding legal proceedings and other matters.

NEW ACCOUNTING STANDARDS

Refer to Note 12 for a summary of recently adopted accounting standards.

PRODUCT REVENUES AND PRODUCTION COSTS

Mining Product Revenues and Unit Net Cash Cost

Unit net cash costs per pound of copper and molybdenum are measures intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for the respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. These measures are presented by other metals mining companies, although our measures may not be comparable to similarly titled measures reported by other companies.

We present gross profit per pound of copper in the following tables using both a “by-product” method and a “co-product” method. We use the by-product method in our presentation of gross profit per pound of copper because (i) the majority of our revenues are copper revenues, (ii) we mine ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of our costs to revenues from the copper, gold, molybdenum and other metals we produce and (iv) it is the method used by our management and our Board to monitor our mining operations and to compare mining operations in certain industry publications. In the co-product method presentations, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent our metals sales volumes and realized prices change.

We show revenue adjustments for prior period open sales as a separate line item. Because these adjustments do not result from current period sales, these amounts have been reflected separately from revenues on current period

sales. Noncash and other costs, which are removed from site production and delivery costs in the calculation of unit

net cash costs, consist of items such as stock-based compensation costs, start-up costs, inventory adjustments,

long-lived asset impairments, restructuring and/or unusual charges. As discussed above, gold, molybdenum and

other metal revenues at copper mines are reflected as credits against site production and delivery costs in the by-product method. The following schedules are presentations under both the by-product and co-product methods

together with reconciliations to amounts reported in our consolidated financial statements.

CAUTIONARY STATEMENT

Our discussion and analysis contains forward-looking statements in which we discuss our potential future performance. Forward-looking statements are all statements other than statements of historical facts, such as projections or expectations relating to ore grades and milling rates, production and sales volumes, unit net cash costs, operating cash flows, capital expenditures, exploration efforts and results, development and production activities and costs, liquidity, tax rates, the impact of copper, gold and molybdenum price changes, the impact of deferred intercompany profits on earnings, reserve estimates, future dividend payments, and share purchases and sales. The words “anticipates,” “may,” “can,” “plans,” “believes,” “estimates,” “expects,” “projects,” “targets,” “intends,” “likely,” “will,” “should,” “to be,” “potential” and any similar expressions are intended to identify those assertions as forward-looking statements.

We caution readers that forward-looking statements are not guarantees of future performance and actual results may differ materially from those anticipated, projected or assumed in the forward-looking statements. Important factors that can cause our actual results to differ materially from those anticipated in the forward-looking statements include supply of and demand for, and prices of, copper, gold and molybdenum; mine sequencing; production rates; potential effects of cost and capital expenditure reductions and production curtailments on financial results and cash flow; potential inventory adjustments; potential impairment of long-lived mining assets; the outcome of negotiations with the Indonesian government regarding PT-FI’s long-term operating rights; the potential effects of violence in Indonesia generally and in the province of Papua; industry risks; regulatory changes (including adoption of financial assurance regulations as proposed by the U.S. Environmental Protection Agency under CERCLA for the hard rock mining industry); political risks; labor relations; weather- and climate-related risks; environmental risks; litigation results (including the final disposition of the unfavorable Indonesia Tax Court ruling relating to surface water taxes and the outcome of Cerro Verde’s royalty dispute with the Peruvian national tax authority); and other factors described in more detail in Part I, Item 1A. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2016, filed with the SEC as updated by our subsequent filings with the SEC. With respect to our operations in Indonesia, such factors include whether PT-FI will be able to resolve complex regulatory matters in Indonesia and continue to export copper after December 31, 2017.

Investors are cautioned that many of the assumptions upon which our forward-looking statements are based are likely to change after the forward-looking statements are made, including for example commodity prices, which we cannot control, and production volumes and costs, some aspects of which we may not be able to control. Further, we may make changes to our business plans that could affect our results. We caution investors that we do not intend to update forward-looking statements more frequently than quarterly notwithstanding any changes in our assumptions, changes in business plans, actual experience or other changes, and we undertake no obligation to update any forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no material changes in our market risks during the nine-month period ended September 30, 2017. For additional information on market risks, refer to “Disclosures About Market Risks” included in Part II, Items 7. and 7A. of our annual report on Form 10-K for the year ended December 31, 2016. For projected sensitivities of our operating cash flow to changes in commodity prices, refer to “Outlook” in Part I, Item 2. of this quarterly report on Form 10-Q for the period ended September 30, 2017; for projected sensitivities of our provisionally priced copper sales and derivative instruments to changes in commodity prices refer to “Consolidated Results – Revenues” in Part I, Item 2. of this quarterly report on Form 10-Q for the period ended September 30, 2017.

Item 4. Controls and Procedures.

(a) Evaluation of disclosure controls and procedures. Our chief executive officer and chief financial officer, with the participation of management, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this quarterly report on Form 10-Q. Based on their evaluation, they have concluded that our disclosure controls and procedures are effective as of September 30, 2017.

(b) Changes in internal control over financial reporting. There has been no change in our internal control over financial reporting that occurred during the quarter ended September 30, 2017, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. OTHER INFORMATION

Item 1. Legal Proceedings.

We are involved in numerous legal proceedings that arise in the ordinary course of our business or that are associated with environmental issues arising from legacy operations conducted over the years by Freeport Minerals Corporation and its affiliates. We are also involved from time to time in other reviews, investigations and proceedings by government agencies, some of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief.

Management does not believe, based on currently available information, that the outcome of any proceeding reported in Note 9 of this quarterly report on Form 10-Q for the period ended September 30, 2017, and in Part I, Item 3. “Legal Proceedings” and Note 12 of our annual report on Form 10-K for the year ended December 31, 2016, as updated in Note 9 in our quarterly reports on Form 10-Q for the quarters ended March 31, 2017, and June 30, 2017, will have a material adverse effect on our financial condition; although individual outcomes could be material to our operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period.

Environmental Proceedings

Notices of Violation - Cerro Verde

In September 2017, Cerro Verde paid approximately $148,000, including interest, in connection with final resolution of a Notice of Violation (NOV) issued in December 2006 by Peru’s Agency for Environmental Assessment and Enforcement (OEFA) alleging a spill of dry tailings from a pipeline near the Enlozada tailings dam and findings of dissolved oxidized copper in excess of permissible limits near the Hyuarondo dam.  In September 2017, Cerro Verde also paid approximately $169,000, including interest, in connection with final resolution of an NOV issued in October 2008 by OEFA alleging findings of dissolved oxidized copper in excess of permissible limits, that sprinklers were not being used to moisten stockpiles or the conveyer belt at a concentrator plant, and that the uncleanliness of septic tanks at the transfer station resulted in findings of raw sewage in the treated water used for landscaping around administrative buildings.

Item 1A. Risk Factors.

There have been no material changes to our risk factors previously disclosed in Part I, Item 1A. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2016, except as disclosed in Part II, Item 1A. “Risk Factors” of our quarterly report on Form 10-Q for the quarter ended March 31, 2017, which provided as follows:

The risk factor “Mine closure and reclamation regulations impose substantial costs on our operations and include requirements that we provide financial assurance supporting those obligations. We also have plugging and abandonment obligations related to our remaining oil and gas properties, and are required to provide bonds or other forms of financial assurance in connection with those operations. Changes in or the failure to comply with these requirements could have a material adverse effect on us” which was included in our annual report on Form 10-K for the year ended December 31, 2016, is updated to add the following:

The United States (U.S.) Environmental Protection Agency extended the comment period for the proposed regulations under Section 108(b) of CERCLA to July 11, 2017. Since filing our annual report on Form 10-K in February 2017, we have evaluated the potential impact of these proposed rules. Based on this evaluation, we believe that, if adopted without material modification, the rules would impose financial responsibility obligations on U.S. hard rock mining operations that are unnecessary, duplicative of existing state and other federal requirements, and unreasonable. Our initial calculations also suggest that the financial responsibility amounts would be difficult, if not impossible, for us and others to meet with corporate resources, and would be extremely expensive, if not impossible, to finance with third-party financial instruments such as letters of credit, bonds or insurance. We and others in the industry will continue to participate in the public comment process and oppose the adoption of these rules in anything like their proposed form, as adoption in that form would severely harm the international competitiveness of the U.S. hard rock mining industry and would materially and adversely affect our cash flows, results of operations and financial condition.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

There were no unregistered sales of equity securities during the three months ended September 30, 2017.

There were no shares of common stock purchased by us during the three months ended September 30, 2017. On July 21, 2008, our Board of Directors approved an increase in our open-market share purchase program for up to 30 million shares. There have been no purchases under this program since 2008. This program does not have an expiration date. At September 30, 2017, there were 23.7 million shares that could still be purchased under the program.

Item 4. Mine Safety Disclosures.

The safety and health of all employees is our highest priority. Management believes that safety and health considerations are integral to, and compatible with, all other functions in the organization and that proper safety and health management will enhance production and reduce costs. Our approach towards the safety and health of our workforce is to continuously improve performance through implementing robust management systems and providing adequate training, safety incentive and occupational health programs. The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this quarterly report on Form 10-Q.

Exhibit 95.1

Mine Safety and Health Administration (MSHA) Safety Data

FCX's U.S. mining operations are subject to regulations issued by MSHA under the U.S. Federal Mine Safety and Health Act of 1977 (the Mine Act). MSHA inspects our U.S. mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders can be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed. The number of citations, orders and proposed assessments varies depending on the size and type (underground or surface) of the mine, among other factors.

The following disclosures have been provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Act).

Mine Safety Data. Following provides additional information about references used in the following table to describe the categories of violations, orders or citations issued by MSHA under the Mine Act:

• Section 104 S&S Citations: Citations issued by MSHA under Section 104(a) of the Mine Act for violations of health or safety standards that could significantly and substantially contribute to a serious injury if left unabated.

• Section 104(b) Orders: Orders issued under Section 104(b) of the Mine Act, which represent a failure to abate a citation under Section 104(a) within the period prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

• Section 104(d) Citations and Orders: Citations and orders issued by MSHA under Section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards. These types of violations could significantly and substantially contribute to a serious injury; however, the conditions do not cause imminent danger (refer to discussion of imminent danger orders below).

• Section 110(b)(2) Violations: Flagrant violations identified by MSHA under Section 110(b)(2) of the Mine Act. The term flagrant with respect to a violation is defined as “a reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have expected to cause, death or serious bodily injury.”

• Section 107(a) Orders: Orders issued by MSHA under Section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed. Orders issued under Section 107(a) of the Mine Act require the operator of the mine to cause all persons (except authorized persons) to be withdrawn from the mine until the imminent danger and the conditions that caused such imminent danger cease to exist.

The following table details the violations, citations and orders issued to us by MSHA during the three months ended September 30, 2017:

(1) MSHA assigns an identification number to each mine or operation and may or may not assign separate identification numbers to related facilities.

(2) Amounts represent the total dollar value of proposed assessments received on or before October 31, 2017, for citations or orders issued by MSHA during the three months ended September 30, 2017. FCX is not currently contesting any of these proposed assessments.

Pending Legal Actions. The following table provides a summary of legal actions pending before the Federal Mine Safety and Health Review Commission (the Commission) as well as the aggregate number of legal actions instituted and resolved during the three months ended September 30, 2017. The Commission is an independent adjudicative agency established by the Mine Act that provides administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under Section 105 of the Mine Act.

The following provides additional information of the types of proceedings that may be brought before the Commission:

• Contest Proceedings - A contest proceeding may be filed by an operator to challenge the issuance of a citation or order issued by MSHA.

• Civil Penalty Proceedings - A civil penalty proceeding may be filed by an operator to challenge a civil penalty MSHA has proposed for a violation contained in a citation or order. FCX does not institute civil penalty proceedings based solely on the assessment amount of proposed penalties. Any initiated adjudications described in the table below address substantive matters of law and policy instituted on conditions that are alleged to be in violation of mandatory standards or the Mine Act.

• Discrimination Proceedings - Involves a miner's allegation that he or she has suffered adverse employment action because he or she engaged in activity protected under the Mine Act, such as making a safety complaint. Also includes temporary reinstatement proceedings involving cases in which a miner has filed a complaint with MSHA stating that he or she has suffered discrimination and the miner has lost his or her position.

• Compensation Proceedings - A compensation proceeding may be filed by miners entitled to compensation when a mine is closed by certain closure orders issued by MSHA. The purpose of the proceeding is to determine the amount of compensation, if any, due to miners idled by the orders.

• Temporary Relief - Applications for temporary relief are applications filed under section 105(b)(2) of the Mine Act for temporary relief from any modification or termination of any order.

• Appeals - An appeal may be filed by an operator to challenge judges decisions or orders to the commission, including petitions for discretionary review and review by the commission on its own motion.

With the exception of the accounting for discontinued operations, assets held for sale, the remeasurement of a pension plan and charges related to a continuing royalty dispute with respect to historical periods at FCX’s mine in Peru, all such adjustments are, in the opinion of management, of a normal recurring nature. As a result of FCX’s sale of its interest in TF Holdings Limited (TFHL), FCX has reported TFHL as discontinued operations for all periods presented in the unaudited consolidated financial statements (refer to Note 2). Operating results for the nine-month period ended September 30, 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

Indonesia Mining. As a result of the first-quarter 2017 regulatory restrictions and uncertainties regarding long-term investment stability, PT Freeport Indonesia (PT-FI) took actions to adjust its cost structure, reduce its workforce and slow investments in its underground development projects and new smelter. These actions included workforce reductions through furlough and voluntary retirement programs. Following the furlough and voluntary retirement programs, a significant number of employees and contractors elected to participate in an illegal strike action beginning in May 2017, and were subsequently deemed to have voluntarily resigned under existing laws and regulations. As a result, PT-FI recorded charges to operating income for employee severance and related costs totaling $9 million for third-quarter 2017 and $113 million for the first nine months of 2017.

Additionally, because of the significant reduction in workforce, PT-FI was required to remeasure its pension assets and pension benefit obligation as of June 30, 2017. The discount rate and rate of compensation increase used for the June 30, 2017, remeasurement were 7.50 percent and 4.00 percent, respectively, compared to the December 31, 2016, discount rate of 8.25 percent and the rate of compensation increase of 8.00 percent. The expected long-term rate of return on the plan assets was unchanged (7.75 percent). The remeasurement and curtailment resulted in the projected benefit obligation declining by $145 million and plan assets declining by $21 million. In addition, PT-FI recognized a curtailment loss of $4 million in second-quarter 2017 and for the first nine months of 2017. As of September 30, 2017, the funded status of PT-FI’s pension plan was a net asset of $36 million (included in other assets in the consolidated balance sheet), compared with a net liability of $90 million (included in other liabilities in the consolidated balance sheet) as of December 31, 2016.

Oil and Gas Properties. During 2016, FCX Oil & Gas LLC (FM O&G, a wholly owned subsidiary of FCX) determined the carrying values of certain of its unevaluated properties were impaired. During the first nine months of 2016, FM O&G transferred $3.2 billion of costs (including $3.1 billion in first-quarter 2016) associated with unevaluated properties to the full cost pool, mostly reflecting impairment of the carrying values of unevaluated properties. The transfer of unevaluated properties to the full cost pool, along with the impact of the reduction in twelve-month historical prices and reserve revisions in 2016 caused net capitalized costs to exceed the related ceiling test limitation under full cost accounting rules. As a result, FM O&G recognized impairment charges of $239 million in third-quarter2016 and $4.3 billion for the first nine months of 2016. Refer to Note 1 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

DISPOSITIONS

TF Holdings Limited - Discontinued Operations.FCX hada70 percent interest in TFHL, which owns 80 percent of Tenke Fungurume Mining S.A. (TFM or Tenke) located in the Democratic Republic of Congo (DRC). On November 16, 2016, FCX completed the sale of its interest in TFHL to China Molybdenum Co., Ltd. (CMOC) for $2.65 billion in cash (before closing adjustments) and contingent consideration of up to $120 million in cash, consisting of $60 million if the average copper price exceeds $3.50 per pound and $60 million if the average cobalt price exceeds $20 per pound, both during calendar years 2018 and 2019. The contingent consideration is considered a derivative, and at September 30, 2017, the related fair value of $58 million was recorded in other assets on the consolidated balance sheets. During the first nine months of 2017, the fair value of the contingent consideration derivative increased by $45 million ($3 million in third-quarter2017), primarily resulting from higher cobalt prices, and was recorded in net income (loss) from discontinued operations.

In accordance with accounting guidance, FCX has reported the results of operations of TFHL as discontinued operations in the consolidated statements of operations. The consolidated statements of cash flows are reported on a combined basis without separately presenting discontinued operations.

Net income (loss) from discontinued operations in the consolidated statements of operations consists of the following (in millions):

a. In accordance with accounting guidance, amounts are net of (eliminations) recognition of intercompany sales totaling $(53) million in third-quarter2016, $13 million for the first nine months of 2017 and $(125) million for the first nine months of 2016.

b. In accordance with accounting guidance, interest associated with FCX’s term loan that was required to be repaid as a result of the sale of TFHL has been allocated to discontinued operations.

c. Includes a gain of $3 million in third-quarter2017 and $45 million for the first nine months of 2017 associated with the change in the fair value of contingent consideration.

d. In accordance with accounting guidance, an estimated loss on disposal was recorded and adjusted through closing of the transaction in November 2016.

Cash flows from discontinued operations included in the consolidated statements of cash flows for the nine months ended September 30, 2016, follow (in millions):

Oil and Gas Operations.On July 31, 2017, FM O&G sold certain property interests in the Gulf of Mexico Shelf for cash consideration of $62 million, before closing adjustments, with an effective date of April 1, 2017. On March 17, 2017, FM O&G sold property interests in the Madden area in central Wyoming for cash consideration of $17.5 million, before closing adjustments. Under the full cost accounting rules, the sales resulted in the recognition of gains of $33 million in third-quarter2017 and $49 million for the first nine months of 2017 because the reserves associated with these properties were significant to the full cost pool.

On June 17, 2016, FM O&G sold certain oil and gas royalty interests for cash consideration of $102 million, before closing adjustments. In addition, on July 25, 2016, FM O&G sold its Haynesville shale assets for cash consideration of $87 million, before closing adjustments. Under the full cost accounting rules, the proceeds from these transactions were recorded as a reduction to capitalized oil and gas properties, with no gain or loss recognition for the first nine months of2016 because the reserves were not significant to the full cost pool.

Morenci. On May 31, 2016, FCX sold a 13 percent undivided interest in its Morenci unincorporated joint venture to SMM Morenci, Inc. for $1.0 billion in cash. FCX recorded a $576 million gain for the first nine months of2016 and used losses to offset cash taxes on the transaction. A portion of the proceeds from the transaction was used to repay borrowings under FCX's unsecured bank term loan and revolving credit facility. As a result of the transaction, the unincorporated joint venture is owned 72 percent by FCX, 15 percent by Sumitomo Metal Mining Arizona, Inc. and 13 percent by SMM Morenci, Inc.

Timok. On May 2, 2016, Freeport Minerals Corporation (FMC), a wholly owned subsidiary of FCX, sold an interest in the Timok exploration project in Serbia to Global Reservoir Minerals Inc. (now known as Nevsun Resources, Ltd.) for consideration of $135 million in cash and contingent consideration of up to $107 million payable to FCX in stages upon achievement of defined development milestones. As a result of this transaction, FCX recorded a gain of $133 million for the first nine months of2016, and no amounts were recorded for contingent consideration under the loss recovery approach.

Assets Held for Sale. Freeport Cobalt includes the large-scale cobalt refinery in Kokkola, Finland, and the related sales and marketing business, in which FCX owns an effective 56 percent interest. Kisanfu is a copper and cobalt exploration project, located near Tenke, in which FCX holds a 100 percent interest. As a result of the sale of TFHL, FCX expects to sell its interest in Freeport Cobalt and Kisanfu, and the assets and liabilities of Freeport Cobalt and Kisanfu are classified as held for sale in the consolidated balance sheets. During the first nine months of2017, a favorable adjustment of $13 million was recorded in net gain on sales of assets in the consolidated statements of operations associated with the estimated fair value less costs to sell for the Kisanfu exploration project. The adjustment was limited to the reduction in the carrying value when the Kisanfu exploration project was initially classified as held for sale in November 2016.

Earnings Per Share

EARNINGS PER SHARE

FCX calculates its basic net income (loss) per share of common stock under the two-class method and calculates its diluted net income (loss) per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income (loss) per share of common stock was computed by dividing net income (loss) attributable to common stockholders (after deducting accumulated dividends and undistributed earnings to participating securities) by the weighted-average shares of common stock outstanding during the period. Diluted net income (loss) per share of common stock was calculated by including the basic weighted-average shares of common stock outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be anti-dilutive.

Reconciliations of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted net income (loss) per share follow (in millions, except per share amounts):

Income Taxes

INCOME TAXES

Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. FCX’s consolidated effective income tax rate was 47 percent for the first nine months of 2017 and (2) percent for first nine months of 2016. Geographic sources of FCX’s (provision for) benefit from income taxes follow (in millions):

a. Includes net tax (charges) credits of $(10) million for third-quarter2017 and $21 million for the first nine months of 2017 associated with alternative minimum tax credit carryforwards. The third quarter and first nine months of 2016 include net tax credits of $332 million and $290 million, respectively, associated with alternative minimum tax credits, changes to valuation allowances and net operating loss carryback claims.

b. Includes net charges of $2 million associated with the Cerro Verde mining royalties dispute, consisting of tax charges of $127 million for disputed royalties and other related mining taxes for the period October 2011 through the year 2013 (when royalties were determined based on operating income), mostly offset by a tax benefit of $125 million associated with disputed royalties and other related mining taxes for the period December 2006 through the year 2013.

As a result of the unfavorable Peruvian Supreme Court ruling on the Cerro Verde royalty dispute, FCX recorded pre-tax charges of $357 million to income from continuing operations and $2 million of net tax expense for the first nine months of 2017. FCX’s consolidated effective income tax rate was 39 percent for the first nine months of 2017 excluding these charges.

As a result of the impairment to U.S. oil and gas properties, FCX recorded tax charges of $1.6 billion for the first nine months of 2016 to establish a valuation allowance primarily against U.S. federal and state deferred tax assets that will not generate a future benefit. FCX’s consolidated effective income tax rate was 32 percent for the first nine months of 2016 excluding these tax charges.

Revolving Credit Facility. At September 30, 2017, there were no borrowings outstanding and $36 million in letters of credit issued under FCX’s revolving credit facility, resulting in availability of approximately $3.5 billion, of which approximately $1.5 billion could be used for additional letters of credit.

Senior Notes Issued by FCX. In March 2017, FCX’s 2.15% Senior Notes matured, and the $500 million outstanding principal balance was repaid.

Cerro Verde Credit Facility and Shareholder Loans. In June 2017, Cerro Verde’s credit facility was amended to increase the commitment by $225 million to $1.5 billion, modify the amortization schedule and to extend the maturity date to June 19, 2022. The amended credit facility amortizes in four installments, with $225 million due on December 31, 2020, $225 million due on June 30, 2021, $525 million due on December 31, 2021, and the remaining balance due on the maturity date of June 19, 2022. All other terms, including the interest rates, remain the same. The interest rate on Cerro Verde's credit facility was 3.14 percent at September 30, 2017. Cerro Verde used proceeds from its amended credit facility plus available cash to repay the balance of its shareholder loans in June 2017. Refer to Note 8 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

Exchanges and Early Extinguishment of Debt. During third-quarter2017, FCX redeemed in full certain senior notes. A summary of these early debt extinguishments follows (in millions):

	Principal Amount		Net Adjustments		Book Value		Redemption Value		Gain
FCX 6.125% Senior Notes due 2019	$	179	$	5	$	184	$	182	$	2

	$	543	$	23	$	566	$	555	$	11

Partially offsetting the $11 million gain on early extinguishment of certain senior notes was a net loss of $3 million, primarily associated with the modification of Cerro Verde’s credit facility in second-quarter 2017.

During the second and third quarters of 2016, FCX redeemed certain senior notes in exchange for its common stock, which resulted in gains of $15 million in third-quarter2016 and $54 million for the first nine months of 2016. Partially offsetting the gains were $3 million in losses, primarily associated with the modification of FCX’s revolving credit facility in first-quarter 2016. Refer to Notes 8 and 10 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

Interest Expense, Net. Consolidated interest costs from continuing operations (before capitalization and excluding $141 million of interest expense associated with disputed Cerro Verde royalties recorded in third-quarter2017) totaled $196 million in third-quarter2017, $211 million in third-quarter2016, $583 million for the first nine months of 2017 and $647 million for the first nine months of 2016. Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $33 million in third-quarter2017, $24 million in third-quarter2016, $91 million for the first nine months of 2017 and $66 million for the first nine months of 2016. Capitalized interest added to oil and gas properties not subject to amortization totaled $7 million for the first nine months of 2016 (none in third-quarter2016 or 2017).

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments

FINANCIAL INSTRUMENTS

FCX does not purchase, hold or sell derivative financial instruments unless there is an existing asset or obligation, or it anticipates a future activity that is likely to occur and will result in exposure to market risks, which FCX intends to offset or mitigate. FCX does not enter into any derivative financial instruments for speculative purposes, but has entered into derivative financial instruments in limited instances to achieve specific objectives. These objectives principally relate to managing risks associated with commodity price changes, foreign currency exchange rates and interest rates.

Commodity Contracts. From time to time, FCX has entered into derivative contracts to hedge the market risk associated with fluctuations in the prices of commodities it purchases and sells. Derivative financial instruments used by FCX to manage its risks do not contain credit risk-related contingent provisions. As of September 30, 2017, and December 31, 2016, FCX had no price protection contracts relating to its mine production. A discussion of FCX’s derivative contracts and programs follows.

Derivatives Designated as Hedging Instruments – Fair Value Hedges

Copper Futures and Swap Contracts. Some of FCX’s U.S. copper rod customers request a fixed market price instead of the Commodity Exchange Inc. (COMEX) average copper price in the month of shipment. FCX hedges this price exposure in a manner that allows it to receive the COMEX average price in the month of shipment while the customers pay the fixed price they requested. FCX accomplishes this by entering into copper futures or swap contracts. Hedging gains or losses from these copper futures and swap contracts are recorded in revenues. FCX did not have any significant gains or losses resulting from hedge ineffectiveness during the nine-month periods ended September 30, 2017 and 2016. At September 30, 2017, FCX held copper futures and swap contracts that qualified for hedge accounting for 46 million pounds at an average contract price of $2.83 per pound, with maturities through June 2019.

A summary of gains (losses) recognized in revenues for derivative financial instruments related to commodity contracts that are designated and qualify as fair value hedge transactions, along with the unrealized gains (losses) on the related hedged item follows (in millions):

Derivatives Not Designated as Hedging Instruments

Embedded Derivatives. As described in Note 1 to FCX’s annual report on Form 10-K for the year ended December 31, 2016, under “Revenue Recognition,” certain FCX copper concentrate, copper cathode and gold sales contracts provide for provisional pricing primarily based on the London Metal Exchange (LME) copper price or the COMEX copper price and the London Bullion Market Association (London) gold price at the time of shipment as specified in the contract. Similarly, FCX purchases copper under contracts that provide for provisional pricing. FCX applies the normal purchases and normal sales scope exception in accordance with derivatives and hedge accounting guidance to the host sales agreements since the contracts do not allow for net settlement and always result in physical delivery. Sales and purchases with a provisional sales price contain an embedded derivative (i.e., the price settlement mechanism is settled after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale or purchase of the metals contained in the concentrate or cathode at the then-current LME or COMEX copper price or the London gold price as defined in the contract. Mark-to-market price fluctuations from these embedded derivatives related to continuing operations are recorded through the settlement date and are reflected in revenues for sales contracts and in cost of sales as production and delivery costs for purchase contracts. Mark-to-market price fluctuations associated with embedded derivatives for discontinued operations, which were minimal, are included in discontinued operations for all periods presented in these financial statements.

A summary of FCX’s embedded derivatives at September 30, 2017, follows:

	Open Positions	Average Price Per Unit				Maturities Through
		Contract		Market
Embedded derivatives in provisional sales contracts:
Copper (millions of pounds)	546	$	2.84	$	2.93	February 2018
Gold (thousands of ounces)	194	1,318		1,287		December 2017
Embedded derivatives in provisional purchase contracts:
Copper (millions of pounds)	155	2.83		2.93		January 2018

Copper Forward Contracts. Atlantic Copper, FCX’s wholly owned smelting and refining unit in Spain, enters into copper forward contracts designed to hedge its copper price risk whenever its physical purchases and sales pricing periods do not match. These economic hedge transactions are intended to hedge against changes in copper prices, with the mark-to-market hedging gains or losses recorded in cost of sales. At September 30, 2017, Atlantic Copper held net copper forward purchase contracts for 5 million pounds at an average contract price of $2.95 per pound, with maturities through October 2017.

Summary of Gains (Losses). A summary of the realized and unrealized gains (losses) recognized in operating income (loss) for commodity contracts that do not qualify as hedge transactions, including embedded derivatives, follows (in millions):

Credit Risk. FCX is exposed to credit loss when financial institutions with which it has entered into derivative transactions (commodity, foreign exchange and interest rate swaps) are unable to pay. To minimize the risk of such losses, FCX uses counterparties that meet certain credit requirements and periodically reviews the creditworthiness of these counterparties. FCX does not anticipate that any of the counterparties it deals with will default on their obligations. As of September 30, 2017, the maximum amount of credit exposure associated with derivative transactions was $78 million.

Other Financial Instruments. Other financial instruments include cash and cash equivalents, accounts receivable, restricted cash, investment securities, legally restricted funds, accounts payable and accrued liabilities, and long-term debt. The carrying value for cash and cash equivalents (which included time deposits of $1.9 billion at September 30, 2017, and $64 million at December 31, 2016), accounts receivable, restricted cash, and accounts payable and accrued liabilities approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 8 for the fair values of investment securities, legally restricted funds and long-term debt).

In addition, as of September 30, 2017, FCX has contingent consideration assets related to certain 2016 asset sales (refer to Note 8 for the related fair value and to Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion of these instruments).

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENT

Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). FCX recognizes transfers between levels at the end of the reporting period. FCX did not have any significant transfers in or out of Level 1, 2 or 3 for third-quarter2017.

FCX’s financial instruments are recorded on the consolidated balance sheets at fair value except for contingent consideration associated with the sale of the Deepwater Gulf of Mexico (GOM) oil and gas properties (which was recorded under the loss recovery approach) and debt. A summary of the carrying amount and fair value of FCX’s financial instruments, other than cash and cash equivalents, accounts receivable, restricted cash, and accounts payable and accrued liabilities (refer to Note 7) follows (in millions):

Excludes time deposits (which approximated fair value) included in (i) other current assets of $41 million at September 30, 2017, and $28 million at December 31, 2016, and (ii) other assets of $122 million at both September 30, 2017, and December 31, 2016, primarily associated with an assurance bond to support PT-FI’s commitment for smelter development in Indonesia.

c. Refer to Note 7 for further discussion and balance sheet classifications.

d. Recorded at cost except for debt assumed in acquisitions, which were recorded at fair value at the respective acquisition dates.

e. Included in accounts payable and accrued liabilities.

Valuation Techniques. The U.S. core fixed income fund is valued at net asset value (NAV). The fund strategy seeks total return consisting of income and capital appreciation primarily by investing in a broad range of investment-grade debt securities, including U.S. government obligations, corporate bonds, mortgage-backed securities, asset-backed securities and money market instruments. There are no restrictions on redemptions (which are usually within one business day of notice).

Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

Equity securities are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy.

Fixed income securities (government securities, corporate bonds, asset-backed securities, collateralized mortgage-backed securities and municipal bonds) are valued using a bid-evaluation price or a mid-evaluation price. A bid-evaluation price is an estimated price at which a dealer would pay for a security. A mid-evaluation price is the average of the estimated price at which a dealer would sell a security and the estimated price at which a dealer would pay for a security. These evaluations are based on quoted prices, if available, or models that use observable inputs and, as such, are classified within Level 2 of the fair value hierarchy.

FCX’s embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales are valued using only quoted monthly LME or COMEX copper forward prices and the London gold forward price at each reporting date based on the month of maturity (refer to Note 7 for further discussion); however, FCX’s contracts themselves are not traded on an exchange. As a result, these derivatives are classified within Level 2 of the fair value hierarchy.

FCX’s derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 7 for further discussion). Certain of these contracts are traded on the over-the-counter market and are classified within Level 2 of the fair value hierarchy based on COMEX and LME forward prices.

The fair value of contingent consideration for the sales of TFHL and onshore California oil and gas properties is calculated based on average commodity price forecasts through applicable maturity dates using a Monte Carlo simulation model. The models use various observable inputs, including Brent crude oil forward prices, historical copper and cobalt prices, volatilities, discount rates and settlement terms. As a result, these contingent consideration assets are classified within Level 2 of the fair value hierarchy.

The fair value of contingent consideration for the sale of Deepwater GOM oil and gas properties is calculated based on a discounted cash flow model using inputs that include third-party reserve estimates, production rates, production timing and discount rates. Because significant inputs are not observable in the market, the contingent consideration is classified within Level 3 of the fair value hierarchy.

The December 31, 2016, fair value of contingent payments for the settlements of drilling rig contracts was calculated based on the average price forecasts of West Texas Intermediate (WTI) crude oil over the 12-month period ending June 30, 2017, using a mean-reverting model. The model used various observable inputs, including WTI crude oil forward prices, volatilities, discount rate and settlement terms. As a result, these contingent payments were classified within Level 2 of the fair value hierarchy. The contingency period for FM O&G’s drilling rig contract settlements ended June 30, 2017, and no additional amounts were paid.

Long-term debt, including current portion, is valued using available market quotes and, as such, is classified within Level 2 of the fair value hierarchy.

The techniques described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with other market participants, the use of different techniques or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the techniques used at September 30, 2017, as compared to those techniques used at December 31, 2016.

A summary of the changes in the fair value of FCX’s Level 3 instrument, contingent consideration for the sale of the Deepwater GOM oil and gas properties, during the first nine months of2017 follows (in millions):

Fair value at January 1, 2017	$	135
Net unrealized gain related to assets still held at the end of the period	3
Fair value at September 30, 2017	$	138

Commitments and Contingencies

CONTINGENCIES AND COMMITMENTS

Environmental

Historical Smelter Sites — Borough of Carteret

As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, from 1920 until 1986, United States Metal Refining Company (USMR), an indirect wholly owned subsidiary of Cyprus Amax Minerals Company, owned and operated a copper smelter and refinery in the Borough of Carteret, New Jersey, on the banks of the Arthur Kill (a narrow waterway that separates New Jersey from Staten Island). As a result of recent off-site soil sampling in public and private areas near the former smelter, FCX increased its associated environmental obligation for known and potential off-site environmental remediation by recording a $59 million charge to operating income in third-quarter 2017. Additional sampling is ongoing and could result in additional adjustments to the related environmental remediation obligation.

Uranium Mining Sites

As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, the Department of Justice, the U.S. Environmental Protection Agency, the Navajo Nation and two FCX-related subsidiaries reached an agreement regarding the scope of environmental investigation and remediation work for 94 former uranium mining sites on tribal lands, and the related financial contributions of the U.S. government and the FCX subsidiaries. The related Consent Decree was approved by the U.S. District Court for the District of Arizona in second-quarter 2017. Based on updated cash flow and timing estimates, FCX reduced its associated obligation for that contingency by recording a $41 million credit to operating income in second-quarter 2017 after receiving court approval of the Consent Decree.

Litigation

During third-quarter2017, there were no significant updates to previously reported legal proceedings included in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.

Tax and Other Matters

Cerro Verde Royalty Dispute

As reported in FCX’s annual report on Form 10-K for the year ended December 31, 2016, and as subsequently updated in Note 9 of FCX’s quarterly report on Form 10-Q for the quarter ended June 30, 2017, SUNAT, Peru’s national tax authority, has assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006, for the period December 2006 to September 2011. Cerro Verde contested these assessments because it believes its 1998 stability agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing those minerals. No assessments have been issued for the period from October 2011 to December 2013, and no assessments can be issued for years after 2013, as Cerro Verde began paying royalties on all of its production in January 2014 under its new 15-year stability agreement. Since 2014, Cerro Verde has been paying the disputed assessments for the period December 2006 through December 2008 under an installment program ($135 million paid by Cerro Verde through September 30, 2017).

In October 2017, the Peruvian Supreme Court issued a ruling in favor of SUNAT that the assessments of royalties for the year 2008 on ore processed by the Cerro Verde concentrator were proper under Peruvian law.

As a result of the unfavorable Peruvian Supreme Court ruling on the 2008 royalty dispute, Cerro Verde recorded pre-tax charges totaling $357 million ($359 million including net tax charges and $188 million net of noncontrolling interests) in third-quarter 2017, consisting of $240 million in royalty assessments, $147 million of penalties and interest related to the December 2006 to December 2008 assessments, and $97 million for related items (primarily associated with the special mining tax and net assets tax) that Cerro Verde would have incurred under the view that its concentrator was not stabilized.

A summary of the charges recorded in third-quarter 2017 for the Cerro Verde royalty dispute follows (in millions):

Royalty and related assessment charges:
	Production and delivery	$	216		a
	Interest expense, net	141
	Provision for income taxes	2			b
Net loss attributable to noncontrolling interests		(171		)
		$	188

a. Includes $176 million related to disputed royalty assessments for the period from December 2006 to September 2011 (when royalties were determined based on revenues), $6 million of penalties related to the December 2006 to December 2008 royalty assessments and $34 million primarily associated with the net assets tax.

b. Includes tax charges of $127 million for disputed royalties ($64 million) and other related mining taxes ($63 million) for the period October 2011 through the year 2013 when royalties were determined based on operating income, mostly offset by a tax benefit of $125 million associated with disputed royalties and other related mining taxes for the period December 2006 through the year 2013.

Cerro Verde acted in good faith in applying the provisions of its 1998 stability agreement and continues to evaluate alternatives to defend its rights. Cerro Verde intends to seek a waiver available under Peruvian law of penalties and interest associated with this matter and has not recorded charges for potential unpaid penalties and interest totaling $360 million ($193 million net of noncontrolling interests) at September 30, 2017, as FCX believes that Cerro Verde should be successful under Peruvian law in obtaining a waiver. Cerro Verde also intends to file a reimbursement claim with SUNAT for penalties and interest paid under the installment plan for the December 2006 to December 2008 assessments, and may have claims for reimbursement of payments it would not have made in the absence of the stabilization agreement, such as the overpayments made for a special (voluntary) levy (GEM), import duties and civil association contributions. No amounts have been recorded for these potential gain contingencies at September 30, 2017.

Other Peru Tax Matters

There were no significant changes to other Peru tax matters during third-quarter2017 (refer to Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016).

Indonesia Tax Matters

The following information includes a discussion of updates to previously reported Indonesia tax matters included in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.

PT-FI received assessments from the local regional tax authority in Papua, Indonesia, for additional taxes and penalties related to surface water taxes for the period from January 2011 through September 2017. PT-FI is filing objections to these assessments. During 2017, the Indonesia Tax Court issued rulings against PT-FI with respect to assessments for additional taxes and penalties for the period from January 2011 through December 2015 in the amount of $402 million (based on the exchange rate as of September 30, 2017, and including $240 million in penalties). The aggregate amount of assessments received from January 2016 through September 2017 was an additional $114 million, including penalties (based on the exchange rate as of September 30, 2017). No charges have been recorded for these assessments as of September 30, 2017, because PT-FI believes its Contract of Work (COW) exempts it from these payments and that it has the right to contest these assessments (in which FCX estimates the total exposure based on the exchange rate as of September 30, 2017, totals $516 million, including penalties) in the Indonesia Tax Court and ultimately the Indonesia Supreme Court. As of November 7, 2017, PT-FI has not paid and does not intend to pay these assessments unless there is a mechanism established to secure a refund for any such payments upon the final court decision. Additionally, PT-FI is seeking to address this matter in connection with the ongoing negotiations with the Indonesian government to resolve PT-FI’s long-term operating rights.

Indonesia Mining Contract. The following information includes updates to the discussion of PT-FI’s COW included in Note 13 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.

In January and February 2017, the Indonesian government issued new regulations to address the export of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. The new regulations permit the continuation of copper concentrate exports for a five-year period through January 2022, subject to various conditions, including conversion from a contract of work to a special operating license (known as an IUPK, which does not provide the same level of fiscal and legal protections as PT-FI’s COW, which remains in effect), a commitment to the completion of smelter construction in five years and payment of export duties to be determined by the Ministry of Finance. In addition, the new regulations enable application for an extension of operating rights five years before expiration of the IUPK and require foreign IUPK holders to divest a 51 percent interest in the licensed entity to Indonesian interests no later than the tenth year of production. Export licenses would be valid for one-year periods, subject to review every six months, depending on smelter construction progress.

Following the issuance of the January and February 2017 regulations and discussions with the Indonesian government, PT-FI advised the government that it was prepared to convert its COW to an IUPK, subject to obtaining an investment stability agreement providing contractual rights with the same level of legal and fiscal certainty enumerated under its COW, and provided that the COW would remain in effect until it is replaced by a mutually satisfactory alternative. PT-FI also committed to commence construction of a new smelter during a five-year time frame, following approval of the extension of its long-term operating rights.

On January 12, 2017, PT-FI suspended exports in response to Indonesian regulations adopted in January 2014. In addition, as a result of labor disturbances and a delay in the renewal of its export license for anode slimes, PT Smelting’s operations (PT-FI’s 25 percent-owned smelter in Indonesia) were shut down from January 19, 2017, until early March 2017. On February 10, 2017, PT-FI was forced to suspend production as a result of limited storage capacity at PT-FI and PT Smelting. On April 21, 2017, the Indonesian government issued a permit to PT-FI that allowed exports to resume for a six-month period, and PT-FI commenced export shipments.

In mid-February 2017, pursuant to the COW’s dispute resolution process, PT-FI provided formal notice to the Indonesian government of an impending dispute listing the government's breaches and violations of the COW. PT-FI continues to reserve its rights under these provisions.

As a result of the 2017 regulatory restrictions and uncertainties regarding long-term investment stability, PT-FI took actions to adjust its cost structure, slow investments in its underground development projects and new smelter, and place certain of its workforce on furlough programs.

In late March 2017, the Indonesian government amended the regulations to enable PT-FI to retain its COW until replaced with an IUPK accompanied by an investment stability agreement, and to grant PT-FI a temporary IUPK through October 10, 2017, that would allow concentrate exports to resume during this period. In April 2017, PT-FI entered into a Memorandum of Understanding with the Indonesian government confirming that the COW would continue to be valid and honored until replaced by a mutually agreed IUPK and investment stability agreement. PT-FI agreed to continue to pay a five percent export duty during this period.

In August 2017, FCX and the Indonesian government reached an understanding on a framework that would resolve PT-FI’s long-term operating rights. This framework includes (i) conversion from the COW to an IUPK providing PT-FI with long-term operating rights through 2041, (ii) Indonesian government certainty of fiscal and legal terms during the term of the IUPK, (iii) PT-FI commitment to construct a new smelter in Indonesia within five years of reaching a definitive agreement, and (iv) divestment of 51 percent of the project area interests to Indonesian participants at fair market value structured so that FCX retains control over operations and governance of PT-FI. FCX cannot currently predict whether there will be any material accounting and tax implications associated with the divestment.

The framework requires documentation and execution of a definitive agreement, which must be approved by the FCX Board of Directors and joint venture partner Rio Tinto. The parties continue to negotiate to reach agreement on important aspects of implementation of the framework, including the timing and process of divestment, governance matters, and the determination of fair market value, and to complete documentation on a comprehensive agreement for PT-FI’s operations through 2041. The parties have expressed a mutual objective of completing the negotiations and documentation during 2017.

In October 2017, the Indonesian government extended PT-FI’s export rights to December 31, 2017, while negotiations to reach and document a comprehensive long-term definitive agreement based on the agreed framework continue.

Until a definitive agreement is reached, PT-FI has reserved all rights under its COW, including pursuing arbitration under the dispute resolution provisions.

Segment Reporting [Abstract]

Business Segment

BUSINESS SEGMENTS

FCX has organized its mining operations into four primary divisions – North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX’s reportable segments, which include the Morenci, Cerro Verde and Grasberg (Indonesia Mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining.

FCX’s reportable segments previously included U.S. Oil & Gas operations. During 2016, FCX completed the sales of its Deepwater Gulf of Mexico, onshore California and Haynesville oil and gas properties. As a result, beginning in 2017, the U.S. oil and gas operations no longer qualify as a reportable segment, and oil and gas results for all periods presented have been included in Corporate, Other & Eliminations in the following tables. Refer to Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for additional information.

Intersegment sales between FCX’s business segments are based on terms similar to arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums.

FCX defers recognizing profits on sales from its mines to other divisions, including Atlantic Copper (FCX’s wholly owned smelter and refinery in Spain) and on 25 percent of PT-FI’s sales to PT Smelting (PT-FI’s 25-percent-owned smelter and refinery in Indonesia), until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX’s net deferred profits and quarterly earnings.

FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level (included in Corporate, Other & Eliminations), whereas foreign income taxes are recorded and managed at the applicable country level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs, along with some selling, general and administrative costs, are not allocated to the operating divisions or individual segments. Accordingly, the following segment information reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

Guarantor Financial Statements [Text Block]

GUARANTOR FINANCIAL STATEMENTS

All of the senior notes issued by FCX are fully and unconditionally guaranteed on a senior basis jointly and severally by FM O&G LLC, as guarantor, which is a 100-percent-owned subsidiary of FM O&G and FCX. The guarantee is an unsecured obligation of the guarantor and ranks equal in right of payment with all existing and future indebtedness of FM O&G LLC, including indebtedness under FCX’s revolving credit facility. The guarantee ranks senior in right of payment with all of FM O&G LLC’s future subordinated obligations and is effectively subordinated in right of payment to any debt of FM O&G LLC’s subsidiaries. The indentures provide that FM O&G LLC’s guarantee may be released or terminated for certain obligations under the following circumstances: (i) all or substantially all of the equity interests or assets of FM O&G LLC are sold to a third party; or (ii) FM O&G LLC no longer has any obligations under any FM O&G senior notes or any refinancing thereof and no longer guarantees any obligations of FCX under the revolving credit facility or any other senior debt or, in each case, any refinancing thereof.

The following condensed consolidating financial information includes information regarding FCX, as issuer, FM O&G LLC, as guarantor, and all other non-guarantor subsidiaries of FCX. Included are the condensed consolidating balance sheets at September 30, 2017, and December 31, 2016, and the related condensed consolidating statements of comprehensive income (loss) for the three and nine months ended September 30, 2017 and 2016, and the condensed consolidating statements of cash flows for the nine months ended September 30, 2017 and 2016 (in millions), which should be read in conjunction with FCX’s notes to the consolidated financial statements.

New Accounting Standards [Abstract]

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]

NEW ACCOUNTING STANDARDS

In May 2014, the Financial Accounting Standards Board (FASB) issued an Accounting Standard Update (ASU) that provides a single comprehensive revenue recognition model, which will replace most existing revenue recognition guidance, and also requires expanded disclosures. The core principle of the model is that revenue is recognized when control of goods or services has been transferred to customers at an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods within that reporting period. Early adoption is permitted for annual reporting periods beginning after December 15, 2016, and interim reporting periods within that reporting period. FCX will adopt this ASU January 1, 2018, and currently expects to apply the modified retrospective approach under which any cumulative effect adjustment would be recorded to retained earnings as of the adoption date. FCX has substantially completed its review of the impact of this guidance, and based on the terms of its sales contracts, does not expect the guidance to have any impact on its revenue recognition policies or processes. FCX continues to review the impact of the new guidance on its financial reporting and disclosures.

In March 2016, FASB issued an ASU that simplifies various aspects of the accounting for share-based payment transactions, including the income tax consequences, statutory tax withholding requirements, an accounting policy election for forfeitures and the classification on the statement of cash flows. FCX adopted this ASU effective January 1, 2017, and adoption did not have a material impact on its financial statements.

In March 2017, FASB issued an ASU that changes how entities with a defined benefit pension or other postretirement benefit plans present net periodic benefit cost in the income statement. This ASU requires the service cost component of net periodic benefit cost to be presented in the same income statement line item or items as other compensation costs for those employees who are receiving the retirement benefit. In addition, only the service cost component is eligible for capitalization when applicable (i.e., as a cost of inventory or an internally constructed asset). The other components of net periodic benefit cost are required to be presented separately from the service cost component and outside of operating income. These other components of net periodic benefit cost are not eligible for capitalization, and the income statement line item or items must be disclosed. For public entities, this ASU is effective for annual periods beginning after December 15, 2017, and interim reporting periods within that reporting period. Early adoption is permitted. FCX will adopt this ASU on January 1, 2018, and does not expect it to have a material impact on its presentation of the statements of operations.
