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, 2017 . 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 and the remeasurement of a pension plan in second-quarter 2017, all such adjustments are, in the opinion of management, of a normal recurring nature. Operating results for the nine -month period ended September 30, 2018 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.

Assets Held for Sale. FCX continues to market and evaluate the fair value of its effective 56 percent interest in Freeport Cobalt, which includes the large-scale cobalt refinery in Kokkola, Finland, and the related sales and marketing business. During third-quarter 2018, the fair value evaluations resulted in an increase to the estimated fair value less costs to sell of $50 million (included in net gain on sales of assets in the consolidated statements of income).

FCX is continuing to assess opportunities for its Kisanfu copper and cobalt exploration project, located in the Democratic of Republic of Congo, including development of the project on its own or a sale of all or a minority stake in the project. In second-quarter 2018, management concluded it no longer believes that it is probable an outright sale will occur in the near term and the related assets and liabilities should no longer be classified as held for sale. In addition, because of this conclusion, revisions to the consolidated balance sheet as of December 31, 2017, included a $90 million increase to property, plant, equipment and mine development costs, net, with an offsetting reduction in current assets held for sale, and a $27 million increase to deferred income taxes, with an offsetting reduction in current liabilities held for sale.

NOTE 2. EARNINGS PER SHARE

FCX calculates its basic net income per share of common stock under the two-class method and calculates its diluted net income per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income per share of common stock was computed by dividing net income attributable to common stockholders by the weighted-average shares of common stock outstanding during the period. Diluted net income 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.

Outstanding stock options with exercise prices greater than the average market price of FCX’s common stock during the period are excluded from the computation of diluted net income per share of common stock. Stock options for 38 million shares of common stock were excluded for both third-quarter 2018 and third-quarter 2017 , 35 million for the first nine months of 2018 and 42 million for the first nine months of 2017 .

NOTE 4. 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 38 percent for the first nine months of 2018 and 47 percent for the first nine months of 2017 . Geographic sources of FCX’s (provision for) benefit from income taxes follow (in millions):



	Three Months Ended							Nine Months Ended

Total	$	(522	)	$	(387	)		$	(1,543	)		$	(747	)


a.	Includes net tax (charges) credits of $(10) million in third-quarter 2017 and $21 million for the first nine months of 2017 associated with alternative minimum tax credit carryforwards.


b.	Includes a tax credit of $5 million associated with the settlement of a state income tax examination.

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. Refer to Note 8 for further discussion of the Cerro Verde royalty dispute.

As a result of the unfavorable Peruvian Supreme Court ruling on the Cerro Verde royalty dispute in October 2017, FCX recorded pre-tax charges of $357 million to income from continuing operations and $2 million of net tax expense in third-quarter 2017 and 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.

The December 2017 Tax Cuts and Jobs Act (the Act) included significant modifications to then-existing U.S. tax laws and created many new complex tax provisions. As of December 31, 2017, FCX recorded provisional impacts of the tax effects related to specific provisions and continues to evaluate other provisions of the Act. During the first nine months of 2018 , no adjustments were made to the provisional amounts recorded at December 31, 2017, as FCX has not fully completed its analysis of the Act, and the provisional amounts continue to represent FCX’s best estimates. FCX’s current analysis of the Act indicates that there may be adjustments to tax receivables associated

Table of Contents

with minimum tax credit refunds resulting from an ongoing review of tax positions taken in prior years and impacts from the Act’s Global Intangible Low-Taxed Income provisions resulting in use of net operating loss (NOL) carryforwards against income that would not generate a net tax liability absent the availability of NOLs. FCX continues to carry a valuation allowance against all U.S. federal NOLs. During fourth-quarter 2018, FCX will finalize its calculations, including quantifying potential impacts discussed above, as it completes its analysis of the Act.

NOTE 5. DEBT AND EQUITY

a.	Includes additions for unamortized fair value adjustments totaling $60 million at September 30, 2018 ( $97 million at December 31, 2017 ), and is net of reductions for unamortized net discounts and unamortized debt issuance costs totaling $73 million at September 30, 2018 ( $85 million at December 31, 2017 ).

Revolving Credit Facility. At September 30, 2018 , there were no borrowings outstanding and $13 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.

In April 2018, FCX, PT Freeport Indonesia (PT-FI) and FM O&G LLC entered into a new $3.5 billion , five -year, unsecured revolving credit facility, which replaced FCX’s prior revolving credit facility (scheduled to mature on May 31, 2019). The new revolving credit facility is available until April 20, 2023, with $500 million available to PT-FI, and up to $1.5 billion available in letters of credit, and has a substantially similar structure and terms as the prior revolving credit facility. Interest on loans made under the new revolving credit facility will, at the option of FCX, be determined based on the adjusted London Interbank Offered rate or the alternate base rate (each as defined in the new revolving credit facility) plus a spread to be determined by reference to FCX’s credit ratings. The new revolving credit facility contains customary affirmative covenants and representations, and also contains a number of negative covenants that, among other things, restrict, subject to certain exceptions, the ability of FCX's subsidiaries that are not borrowers or guarantors to incur additional indebtedness (including guarantee obligations) and FCX's or its subsidiaries’ ability to: create liens on assets; enter into sale and leaseback transactions; engage in mergers, liquidations and dissolutions; and sell assets. FCX’s new revolving credit facility also contains financial ratios governing maximum total leverage and minimum interest expense coverage. FCX’s total leverage ratio (ratio of total debt to consolidated earnings before interest, taxes, depreciation and amortization (EBITDA), as defined in the credit agreement) cannot exceed 3.75 x, and the minimum interest expense coverage ratio (ratio of consolidated EBITDA to consolidated cash interest expense, as defined in the credit agreement) is 2.25 x.

Senior Notes. In March 2018, FCX’s 2.375% Senior Notes matured, and the $1.4 billion outstanding principal balance was repaid.

On April 4, 2018, FCX redeemed $454 million of aggregate principal amount of outstanding senior notes (as discussed in Early Extinguishment of Debt).

Cerro Verde Credit Facility. In March 2018, Cerro Verde prepaid $100 million of its credit facility.

Table of Contents

Early Extinguishment of Debt. During second-quarter 2018, FCX redeemed in full certain senior notes, and holders received the principal amounts together with the redemption premiums and accrued and unpaid interest up to the redemption date. A summary of these redemptions follows (in millions):




	Principal Amount		Net Adjustments		Book Value		Redemption Value		Gain
FCX 6.75% Senior Notes due 2022	$	404	$	22	$	426	$	418	$	8
FM O&G LLC 6 ⁷ / ₈ % Senior Notes due 2023	50		4		54		52		2
	$	454	$	26	$	480	$	470	$	10

Partially offsetting the $10 million gain were losses of $2 million for the first nine months of 2018 , primarily associated with entering into the new revolving credit facility.

During third-quarter 2017 and for the first nine months of 2017, FCX redeemed in full certain senior notes, which resulted in gains of $11 million . Partially offsetting the gain on early extinguishment of debt for the first nine months of 2017 was a net loss of $3 million , primarily associated with the modification of Cerro Verde’s credit facility in second-quarter 2017.

Interest Expense, Net. Consolidated interest costs (before capitalized interest and excluding interest expense associated with disputed Cerro Verde royalties totaling $1 million in third-quarter 2018 , $7 million for the first nine months of 2018 and $141 million in third-quarter 2017 and for the first nine months of 2017) totaled $166 million in third-quarter 2018 , $196 million in third-quarter 2017 , $501 million for the first nine months of 2018 and $583 million for the first nine months of 2017 . Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $24 million in third-quarter 2018 , $33 million in third-quarter 2017 , $72 million for the first nine months of 2018 and $91 million for the first nine months of 2017 .

Common Stock. In February 2018, FCX’s Board of Directors (the Board) reinstated a cash dividend on FCX’s common stock. On September 26, 2018, the Board declared a quarterly cash dividend of $0.05 per share, which was paid on November 1, 2018, to common stockholders of record as of October 15, 2018.

NOTE 6. 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, 2018 , and December 31, 2017 , FCX had no price protection contracts relating to its mine production. A discussion of FCX’s derivative contracts and programs follows.

Table of Contents

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, 2018 and 2017 . At September 30, 2018 , FCX held copper futures and swap contracts that qualified for hedge accounting for 78 million pounds at an average contract price of $2.81 per pound, with maturities through June 2020.

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, including the unrealized gains (losses) on the related hedged item follows (in millions):

Derivatives Not Designated as Hedging Instruments

Embedded Derivatives. Certain FCX concentrate and cathode contracts are provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month (generally one to four months from the shipment date) based on quoted monthly average copper settlement prices on the London Metal Exchange (LME) or COMEX and quoted monthly average London Bullion Market Association (LBMA) gold settlement prices as specified in the contract. FCX receives market prices based on prices in the specified future month, which results in price fluctuations until the date of settlement. Similarly, FCX purchases copper and cobalt 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 metal price as defined in the contract. Mark-to-market price fluctuations from these embedded derivatives are recorded through the settlement date and are reflected in revenues for sales contracts and in inventory for purchase contracts.

A summary of FCX’s embedded derivatives at September 30, 2018 , follows:



	Open Positions	Average Price Per Unit				Maturities Through
	Open Positions	Contract		Market		Maturities Through
Embedded derivatives in provisional sales contracts:
Copper (millions of pounds)	567	$	2.82	$	2.84	January 2019

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, 2018 , Atlantic Copper held net copper forward sales contracts for 31 million pounds at an average contract price of $2.73 per pound, with maturities through November 2018.

Table of Contents

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 contract 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, 2018 , the maximum amount of credit exposure associated with derivative transactions was $49 million (including embedded derivatives in provisional cobalt purchase contracts of $12 million).

Other Financial Instruments. Other financial instruments include cash and cash equivalents, restricted cash, restricted cash equivalents, accounts receivable, investment securities, legally restricted funds, accounts payable and accrued liabilities, dividends payable and long-term debt. The carrying value for cash and cash equivalents (which included time deposits of $2.4 billion at September 30, 2018 , and $2.9 billion at December 31, 2017 ), restricted cash, restricted cash equivalents, accounts receivable, accounts payable and accrued liabilities, and dividends payable approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 7 for the fair values of investment securities, legally restricted funds and long-term debt).

In addition, as of September 30, 2018 , FCX has contingent consideration assets related to certain 2016 asset sales (refer to Note 7 for the related fair values and to Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2017 , for further discussion of these instruments).

Table of Contents

Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents. The following table provides a reconciliation of total cash, cash equivalents, restricted cash and restricted cash equivalents presented in the consolidated statements of cash flows to the components presented in the consolidated balance sheets (in millions):



	September 30, 2018		December 31, 2017
Balance sheet components:
Cash and cash equivalents	$	4,556	$	4,447
Restricted cash and restricted cash equivalents included in:
Other current assets	116		52
Other assets	127		132
Total cash, cash equivalents, restricted cash and restricted cash equivalents presented in the consolidated statements of cash flows	$	4,799	$	4,631

FCX’s restricted cash and restricted cash equivalents are primarily related to PT-FI’s commitment for smelter development in Indonesia; guarantees and commitments for certain mine closure and reclamation obligations, and customs duty taxes; and funds held as cash collateral for surety bonds related to plugging and abandonment obligations of certain oil and gas properties. Restricted cash and restricted cash equivalents are classified as a current or long-term asset based on the timing and nature of when or how the cash is expected to be used or when the restrictions are expected to lapse. Restricted cash and restricted cash equivalents are comprised of time deposits and money market funds.

NOTE 7. 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 did not have any significant transfers in or out of Level 3 during third-quarter 2018 .

In August 2018, the Financial Accounting Standards Board (FASB) issued a new Accounting Standards Update (ASU) in connection with the disclosure framework project that modifies the disclosure requirements on fair value measurements. FCX early adopted this ASU in third-quarter 2018, which did not have a material impact on its financial statements.

Table of Contents

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 (including those measured at net asset value (NAV) as a practical expedient), other than cash and cash equivalents, restricted cash, restricted cash equivalents, accounts receivable, accounts payable and accrued liabilities, and dividends payable (refer to Note 6) follows (in millions):

a.	Current portion included in other current assets and long-term portion included in other assets.

Excludes time deposits (which approximated fair value) included in (i) other current assets of $116 million at September 30, 2018 , and $52 million at December 31, 2017 , primarily associated with PT-FI’s mine closure and reclamation guarantees and its disputed incremental export duty and (ii) other assets of $126 million at September 30, 2018 , and $123 million at December 31, 2017 , primarily associated with an assurance bond to support PT-FI’s commitment for smelter development in Indonesia.


c.	Refer to Note 6 for further discussion and balance sheet classifications.


d.	Excludes embedded derivatives in provisional cobalt purchase contracts of $12 million at September 30, 2018 , and $24 million at December 31, 2017 (refer to Note 6 for further discussion).


e.	Recorded at cost except for debt assumed in acquisitions, which were recorded at fair value at the respective acquisition dates. In addition, debt excludes $160 million at September 30, 2018 , and $112 million at December 31, 2017 , related to assets held for sale (which approximated fair value).

Valuation Techniques. The U.S. core fixed income fund is valued at 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).

Table of Contents

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 quoted monthly LME or COMEX copper forward prices and the adjusted LBMA gold prices at each reporting date based on the month of maturity (refer to Note 6 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 embedded derivatives on provisional cobalt purchases, included in liabilities held for sale, are valued using quoted monthly LME cobalt forward prices or average published Metals Bulletin cobalt prices, subject to certain adjustments as specified by the terms of the contracts, at each reporting date based on the month of maturity (Level 2).

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 6 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.

As reported in Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2017 , in November 2016, FCX’s sale of its interest in TFHL included 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 the 24-month period beginning January 1, 2018 . Also in 2016, FCX Oil & Gas LLC’s (FM O&G) sale of its onshore California oil and gas properties included contingent consideration of up to $150 million , consisting of $50 million per year for 2018, 2019 and 2020 if the price of Brent crude oil averages over $70 per barrel in each of these calendar years. Future changes in the fair value of the contingent consideration derivative for the sale of TFHL will continue to be recorded in discontinued operations and for the onshore California oil and gas properties will continue to be recorded in operating income. The fair value of the contingent consideration derivative was (i) $57 million at September 30, 2018 , and $74 million at December 31, 2017 , associated with the sale of TFHL and (ii) $110 million at September 30, 2018 , and $34 million at December 31, 2017 , associated with the sale of the onshore California oil and gas properties. The contingent consideration derivatives are included in other assets in the consolidated balance sheets except for $49 million included in other current assets at September 30, 2018 . These fair values were 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.

Table of Contents

As reported in Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2017 , in December 2016, FM O&G’s sale of its Deepwater GOM oil and gas properties included up to $150 million in contingent consideration that was recorded at the total amount under the loss recovery approach. The contingent consideration will be received over time as future cash flows are realized in connection with a third-party production handling agreement for an offshore platform. The first collection occurred in third-quarter 2018. The contingent consideration included in (i) other current assets totaled $12 million at September 30, 2018 , and $24 million at December 31, 2017 , and (ii) other assets totaled $136 million at September 30, 2018 , and $126 million at December 31, 2017 . The fair value of this contingent consideration was calculated based on a discounted cash flow model using inputs that include third-party estimates for reserves, production rates and 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.

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, 2018 , as compared to those techniques used at December 31, 2017 .

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 of 2018 follows (in millions):



Fair value at January 1, 2018	$	134

Fair value at September 30, 2018	$	130

NOTE 8. CONTINGENCIES AND COMMITMENTS

Environmental

Cyprus Tohono, a wholly owned subsidiary of FMC, had historical mining operations in south central Arizona, and groundwater issues at the site are expected to require remediation. FCX increased its recorded environmental obligation for this contingency by $44 million with a corresponding charge to operating income in second-quarter 2018 to reflect an updated assessment of remediation alternatives. There was no significant update to this matter during third-quarter 2018, which was also disclosed in Note 8 of FCX’s quarterly report on Form 10-Q for the quarter ended June 30, 2018.

As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2017 , in third-quarter 2017, FCX recorded a $59 million charge to operating income related to an increase in its Borough of Carteret environmental obligation as a result of off-site soil sampling in public and private areas near the former smelter. In addition, for the first nine months of 2017, FCX recorded a $41 million credit to operating income associated with updated cash flow and timing estimates for environmental obligations at former uranium mining sites in Arizona and New Mexico.

Litigation

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, 2017 , other than the matter below, which was also disclosed in Note 8 of FCX’s quarterly report on Form 10-Q for the quarters ended March 31, 2018, and June 30, 2018.

On April 1, 2016, a purported class action titled David Garcia v. Freeport-McMoRan Oil & Gas LLC was filed in the Superior Court of the State of California for the County of Santa Barbara (Case No. 16CV01305) against FM O&G LLC, an indirect wholly owned subsidiary of FCX. A former FM O&G LLC employee filed the case, which alleges violations of various California employment laws and seeks relief for past wages, overtime, penalties, interest and attorney’s fees. The primary issue underlying the claims is whether compensation must be paid to non-exempt shift workers on platforms located offshore California on the outer-continental shelf for sleep time and other non-working

Table of Contents

time. In June 2016, FM O&G LLC removed the case to the U.S. District Court for the Central District of California, Santa Barbara (the District Court). In September 2016, the District Court dismissed the complaint on the grounds that all four FM O&G LLC platforms potentially involved are located in federal waters, that federal law, not state law, applies, and that federal law does not require an employer to compensate for non-work time. In October 2016, the plaintiff appealed the dismissal to the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit). In June 2017, the Ninth Circuit stayed the Garcia case pending its decision in another case involving essentially the same legal issues, titled Newton v. Parker Drilling Management Services, Ltd . In February 2018, a three-judge panel of the Ninth Circuit ruled in favor of the plaintiffs in the Newton case. Because that decision conflicts with longstanding precedent in the Fifth Circuit and could set a precedent that will result in a reversal of the dismissal in the Garcia case, FM O&G LLC and others filed amicus briefs in April 2018 in support of Parker Drilling’s petition for an en banc rehearing in the Newton case. The Ninth Circuit denied that request on April 27, 2018, but modified its original opinion noting that the question of whether the Ninth Circuit’s holding should be applied retrospectively is reserved for the District Court’s consideration on remand. On May 16, 2018, the Ninth Circuit granted Parker Drilling’s motion to stay further proceedings in the District Court pending the possible filing of a petition for review by the U.S. Supreme Court, which was filed in September 2018. FCX expects to learn whether the U.S. Supreme Court will grant review of the Ninth Circuit’s decision in the Newton case in early 2019. The Ninth Circuit has placed the Garcia case on administrative hold pending the U.S. Supreme Court’s consideration of the petition for review in the Newton case.

The amount of the exposure in the Garcia case is uncertain because FM O&G LLC has potential defenses to the claims even if state law would be applied; however, absent success on those defenses, FCX estimates that the exposure could be in the range of approximately $60 million to $100 million if California wage and hour law is applied retroactively to FM O&G LLC’s operations offshore California. FCX has not established a reserve for this contingency because it believes that its legal position is correct and does not believe a loss is probable. FCX intends to vigorously defend this matter.

Tax and Other Matters

Cerro Verde Royalty Dispute

As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2017, SUNAT, Peru’s national tax authority, assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006, for the period December 2006 to December 2011. In 2018, SUNAT issued assessments for the period January 2012 to December 2013. Cerro Verde contested each of these assessments because it believes that its 1998 stability agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing such minerals. 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 from December 2006 through December 2008 under an installment program ( $177 million paid by Cerro Verde through September 30, 2018). 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 has recorded cumulative charges totaling $487 million ( $355 million net of tax benefits and $187 million net of noncontrolling interests), which were primarily recorded in third-quarter 2017 and consist of $244 million in royalty assessments, $158 million of penalties and interest related to the December 2006 to December 2008 assessments, and $85 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.

In September 2018, the Peruvian Tax Tribunal denied Cerro Verde’s request to waive penalties and interest for the period January 2009 through September 2011. In October 2018, SUNAT served Cerro Verde with demands for payments associated with the Tax Tribunal ruling, including interest and penalties, for the period January 2009 through September 2011. Without waiving its rights to appeal these claims, Cerro Verde expects to begin making monthly payments starting in second-quarter 2019 under a 66-month payment plan and believes amounts paid for penalties and interest would be recoverable following judicial appeals.

Table of Contents

Cerro Verde acted in good faith in applying the provisions of its 1998 stability agreement and continues to evaluate alternatives to defend its rights in the Peruvian judicial system and under international law. Cerro Verde intends to continue to pursue waivers available under Peruvian law of penalties and interest associated with this matter and has not recorded charges for potential penalties and interest totaling $406 million ( $217 million net of noncontrolling interests) at September 30, 2018, for the period January 2009 to December 2013 as FCX believes that Cerro Verde should obtain waivers under Peruvian law.

Other Peru Tax Matters

There were no significant changes to other Peru tax matters during third-quarter 2018 (refer to Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2017 ).

Indonesia Tax Matters

There were no significant 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, 2017 , other than the surface water tax matter below, which was also updated in Note 8 of FCX’s quarterly report on Form 10-Q for the quarters ended March 31, 2018, and June 30, 2018, and the mine development costs matter below.

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 August 2018. PT-FI has filed or will file appeals of these assessments with the Indonesia Tax Court. During the first half of 2018, the Indonesia Tax Court ruled partially in favor of PT-FI with respect to assessments for the period January 2016 through April 2016 by reducing these assessments that amounted to $20 million , including penalties, to $12 million , including penalties (based on the exchange rate at September 30, 2018), or an approximate 40 percent reduction. Hearings in the Indonesia Tax Court related to assessments for the period from May 2016 through April 2017 have concluded with no written decisions issued.

During 2017, PT-FI filed reconsideration request petitions to the Indonesia Supreme Court with respect to assessments for the period from January 2011 through December 2015; and in second-quarter 2018, filed reconsideration request petitions with respect to the Indonesia Tax Court decisions related to the assessments for the period from January 2016 through April 2016. In second-quarter 2018, the Indonesia Supreme Court issued favorable decisions relating to surface water tax assessments for the period January 2011 through July 2015. The Indonesia Supreme Court ruling concluded that PT-FI and the Indonesian government are bound by PT-FI’s Contract of Work (COW), which is lex specialis, and prevails as the law for the parties to the COW that should be carried out in good faith. As a result, FCX estimates the total amount of the assessments, including penalties, (based on the exchange rate at September 30, 2018) for the period from August 2015 through August 2018 totals $173 million , including $87 million in penalties. As of September 30, 2018 , no charges have been recorded for these assessments because PT-FI believes its COW exempts it from these payments. As of November 9, 2018 , PT-FI has not paid and does not intend to pay these assessments.

In September 2018, PT-FI received an unfavorable decision from the Indonesian Tax Court with respect to its appeal of disallowed items on its 2012 corporate income tax return. The most significant disallowed item relates to the tax treatment of mine development costs. A similar decision on PT-FI’s 2014 corporate income tax return was announced in October 2018. PT-FI will appeal these decisions to the Indonesian Supreme Court because it believes the COW is explicit about the tax treatment associated with mine development costs. No adjustments have been recorded for this matter as of September 30, 2018, because FCX believes PT-FI has properly determined and paid its taxes. As of September 30, 2018 , PT-FI had long-term receivables totaling approximately $300 million related to this matter. FCX estimates the potential exposure for penalties for the years 2013, 2016 and 2017 in which the Indonesian tax authorities may assert that PT-FI has underpaid income taxes totals $212 million based on the exchange rate as of September 30, 2018.

Indonesia Mining Contract. Refer to Note 13 of FCX’s annual report on Form 10-K for the year ended December 31, 2017 , for further discussion. The following is the latest information related to PT-FI’s COW and the pending divestment transaction.

In 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 PT-FI’s environmental permit. The Ministry also notified PT-FI that certain operational activities were inconsistent with factors set forth in PT-FI’s 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

Table of Contents

engaged in a process to update its permits through submissions and dialogue with the Ministry that began in late 2014, and PT-FI believes that it has submitted the required documentation to update such permits. In April 2018, the Ministry issued decrees imposing unattainable environmental standards related to PT-FI’s controlled riverine tailings management system that must be complied with by October 2018. The decrees, which PT-FI believes are contrary to the Indonesian government’s obligations under PT-FI’s COW, conflict with PT-FI’s approved environmental management programs and existing environmental permits. If these unattainable environmental standards are not modified or delayed, PT-FI could be adversely affected, including possible shutdown of its operations. PT-FI is currently engaged in constructive discussions with the Ministry in working toward a resolution of these issues. During these discussions, the Ministry has advised PT-FI that the transition period for compliance with the decrees will be extended for up to an additional six months.

On September 27, 2018, FCX, PT-FI, PT Indocopper Investama (PT-II) and PT Indonesia Asahan Aluminium (Persero) (PT Inalum), a state-owned enterprise that currently holds 9.36 percent of PT-FI’s outstanding common stock, entered into a Divestment Agreement on previously agreed economic terms in connection with PT Inalum’s acquisition of shares of PT-FI. Under the Divestment Agreement, PT Inalum will acquire, for cash consideration of $350 million , 100 percent of FCX's interests in PT-II, which owns 9.36 percent of PT-FI (equates to a 5.6 percent interest in the project after 2022). PT Inalum also entered into a definitive agreement with Rio Tinto to acquire, for cash consideration of $3.5 billion , all of Rio Tinto's interests ( 40 percent interest in the project after 2022) associated with its joint venture with PT-FI (the Joint Venture). The arrangements provide for FCX and existing PT-FI shareholders to retain the economics of the revenue and cost sharing arrangements under the Joint Venture and for FCX to continue to manage PT-FI’s operations. Following completion of the transaction, PT Inalum's share ownership will be 51.2 percent of PT-FI (subject to a dividend assignment mechanism to replicate the Joint Venture economics), and FCX's ownership will be 48.8 percent .

PT-FI has agreed to complete the construction of a smelter within five years of the closing, with economics shared pro rata by FCX and PT Inalum according to their respective equity ownership in PT-FI. Concurrent with the closing of the divestment transaction, PT-FI will be granted a special mining license (IUPK) providing long-term mining rights with assured legal and fiscal terms and legal enforceability through 2041. The IUPK issued at closing will initially be valid through 2031 and will include an assured extension through 2041 upon PT-FI’s satisfaction of agreed conditions, including those related to smelter construction and payment of state revenues in accordance with the IUPK.

The transaction, which is expected to close in late 2018 or early 2019, is subject to certain conditions, including the documentation and issuance by the Indonesian government of the IUPK providing for the extension and stability of PT-FI’s long-term mining rights with assured legal and fiscal terms and legal enforceability through 2041 in a form acceptable to FCX and PT Inalum; resolution of environmental regulatory matters that include amendments to the decrees imposing unattainable environmental standards on PT-FI pending before the Ministry satisfactory to the Indonesian government, FCX and PT Inalum; various other Indonesian regulatory actions and approvals, including modification or revocation of current regulations and the implementation of new regulations by the Indonesian government and assurances or approvals by Indonesian tax authorities with respect to the pending transaction; and receipt of customary regulatory approvals from international competition authorities.

The Divestment Agreement provides FCX and PT Inalum with the right to terminate, in certain circumstances, including if the transaction is not consummated on or before December 31, 2018, subject to a six-month extension, if needed, to obtain regulatory approvals from international competition authorities.

PT-FI’s export license is effective through February 15, 2019. In October 2018, PT-FI’s temporary IUPK was extended to November 30, 2018, and PT-FI will continue to seek extensions to its temporary IUPK until closing of the pending transaction. On February 28, 2018, PT Smelting (PT-FI’s 25 percent -owned smelter and refinery in Indonesia) received an extension of its anode slimes export license through February 26, 2019.

Until the pending transaction is completed, PT-FI has reserved all rights under its COW.

NOTE 9. 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.

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 segments, including Atlantic Copper Smelting & Refining and on 25 percent of PT-FI’s sales to PT Smelting, 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 Financial Information by Business Segment 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.

Product Revenues. FCX’s revenues attributable to the products it sold for the third quarters and first nine months of 2018 and 2017 follow (in millions):

NOTE 11. NEW ACCOUNTING STANDARDS

Revenue Recognition. In May 2014, FASB issued a new ASU related to revenue recognition. FCX adopted this standard effective January 1, 2018, under the modified retrospective approach applied to contracts that remain in force at the adoption date. The adoption of this standard did not result in any financial statement impacts or changes to FCX’s revenue recognition policies or processes as revenue is primarily derived from arrangements in which the transfer of control coincides with the fulfillment of performance obligations (refer to Note 1 of FCX’s annual report on Form 10-K for disclosure of FCX’s revenue recognition policy). In connection with the adoption of the standard and consistent with FCX’s policy prior to adoption of the standard, FCX has elected to account for shipping and handling activities performed after control of goods has been transferred to a customer as a fulfillment cost recorded in production and delivery costs on the consolidated statements of income.

FCX recognizes revenue for all of its products upon transfer of control in an amount that reflects the consideration it expects to receive in exchange for those products. Transfer of control is in accordance with the terms of customer contracts, which is generally upon shipment or delivery of the product. While payment terms vary by contract, terms generally include payment to be made within 30 days, but not longer than 60 days. Certain of FCX’s concentrate and cathode sales contracts also provide for provisional pricing, which is accounted for as an embedded derivative (refer to Note 6 for further discussion). For provisionally priced sales, 90 percent to 100 percent of the provisional payment is made upon shipment or within 20 days, and final balances are settled in a contractually specified future month (generally one to four months from the shipment date) based on quoted monthly average copper settlement prices on the LME or COMEX and quoted monthly average LBMA gold settlement prices. FCX’s product revenues are also recorded net of treatment charges, royalties and export duties. Refer to Note 9 for a summary of revenue by product type.

Financial Instruments. In January 2016, FASB issued an ASU that amends the guidance on the classification and measurement of financial instruments. This ASU makes limited changes to prior guidance and amends certain disclosure requirements. FCX adopted this ASU effective January 1, 2018, and adoption did not have a material impact on its financial statements.

Leases. In February 2016, FASB issued an ASU that will require lessees to recognize most leases on the balance sheet. This ASU allows lessees to make an accounting policy election to not recognize a lease asset and liability for leases with a term of 12 months or less and do not have a purchase option that is expected to be exercised. For public entities, this ASU is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. In July 2018, FASB issued a practical expedient, which FCX expects to elect, allowing for entities to apply the provisions of the updated lease guidance at the January 1, 2019, effective date, without adjusting the comparative periods presented. FCX is completing an assessment of its lease portfolio and is in the process of implementing a new system, collecting data, and designing processes and controls to account for its leases in accordance with the new standard. Based on FCX’s efforts to date, it does not expect adoption of this ASU to have a material impact on its financial statements.

Statement of Cash Flows: Restricted Cash. In November 2016, FASB issued an ASU that changes the classification and presentation of restricted cash and restricted cash equivalents on the statement of cash flows. The ASU requires that a statement of cash flows include the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. FCX adopted this ASU effective January 1, 2018, and adjusted its consolidated statement of cash flows for the nine months ended September 30, 2017, to include restricted cash and restricted cash equivalents with cash and cash equivalents.

Table of Contents

The impact of adopting this ASU for the nine months ended September 30, 2017, follows (in millions):



	Previously Reported			Impact of Adoption			Current Presentation
Accrued income taxes and changes in other tax payments included in cash flow from operating activities	$	399		$	(6	)	$	393

Cash, cash equivalents, restricted cash and restricted cash equivalents at end of period	4,957			172			5,129

Net Periodic Pension and Postretirement Benefit Cost. In March 2017, FASB issued an ASU that changes how entities with 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 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 FCX elected to include these other components in other income (expense), net. FCX adopted this ASU effective January 1, 2018, and adjusted its presentation in the consolidated statements of income for the three and nine months ended September 30, 2017, to conform with the new guidance. The impact of adopting this ASU for the three and nine months ended September 30, 2017, follows (in millions):



	Three Months Ended September 30, 2017

Tax Reform Reclassification. In February 2018, FASB issued an ASU that allows entities to elect to reclassify the stranded income tax effects caused by the Act in accumulated other comprehensive income (AOCI) to retained earnings. This election applies to the U.S. federal income tax rate change from 35 percent to 21 percent. FCX elected to early adopt this standard effective July 1, 2018, which resulted in a one-time reclassification totaling $79 million from AOCI to retained earnings in third-quarter 2018 . FCX has not elected to reclassify other “indirect” income tax effects of the Act stranded in AOCI. Any additional income tax effects stranded in AOCI will continue to pass through earnings in future periods as specific classes of AOCI items are reversed in full.

NOTE 12. SUBSEQUENT EVENTS

FCX evaluated events after September 30, 2018 , 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF

FREEPORT-McMoRan INC.

Results of Review of Interim Financial Statements

We have reviewed the accompanying consolidated balance sheet of Freeport-McMoRan Inc. (the Company) as of September 30, 2018 , the related consolidated statements of income, comprehensive income, and equity for the three and nine -month periods ended September 30, 2018 and 2017 , the consolidated statements of cash flows for the nine -month periods ended September 30, 2018 and 2017 , and the related notes (collectively referred to as the “consolidated interim financial statements”). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial statements 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) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2017 , the related consolidated statements of operations, comprehensive income, cash flows and equity for the year then ended, and the related notes (not presented herein); and in our report dated February 20, 2018, we expressed an unqualified audit opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2017 , is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements 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 PCAOB, 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.

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 (MD&A), “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 MD&A and the discussion of our Business and Properties in our annual report on Form 10-K for the year ended December 31, 2017 , 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 (Unaudited). Throughout MD&A, all references to income or losses per share are on a diluted basis.

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.

We believe that we have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. We continue to advance a project to develop the Lone Star oxide ores near the Safford operation in eastern Arizona, and PT Freeport Indonesia (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. We are also pursuing other 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.

Net income attributable to common stock totaled $556 million in third-quarter 2018 , $280 million in third-quarter 2017 , $2.1 billion for the first nine months of 2018 and $776 million for the first nine months of 2017 . The 2018 periods, compared with the 2017 periods, benefited from higher copper and gold sales volumes, partly offset by higher production and delivery costs and income tax expense at our international operations. Refer to “Consolidated Results” for further discussion.

During the first nine months of 2018 , we reduced total debt by $2.0 billion , and our Board of Directors (Board) reinstated a cash dividend on our common stock. For the first nine months of 2018 , the Board has declared quarterly cash dividends totaling $0.15 per share of our common stock. Refer to Note 5 for further discussion.

At September 30, 2018 , we had $4.6 billion in consolidated cash and cash equivalents and $11.1 billion in total debt. We had no borrowings and $3.5 billion available under our $3.5 billion, unsecured revolving credit facility. Refer to Note 5 for further discussion.

In September 2018, we, PT-FI, PT Indocopper Investama (PT-II) and PT Indonesia Asahan Aluminium (Persero) (PT Inalum) entered into a Divestment Agreement on previously agreed economic terms in connection with PT Inalum’s acquisition of shares of PT-FI. Under the Divestment Agreement, PT Inalum will acquire, for cash consideration of $350 million, 100 percent of our interests in PT-II, which owns 9.36 percent of PT-FI (equates to a 5.6 percent interest after 2022). PT Inalum also entered into a definitive agreement with Rio Tinto to acquire for cash consideration of $3.5 billion, all of Rio Tinto's interests (40 percent interest after 2022) associated with its joint venture with PT-FI (the Joint Venture). The arrangements provide for us and existing PT-FI shareholders to retain the economics of the revenue and cost sharing arrangements under the Joint Venture and for us to continue to manage PT-FI's operations. Following completion of the transaction, PT-FI will have an expanded asset base as a result of Rio Tinto’s interest being merged into PT-FI, and PT Inalum's share ownership will be 51.2 percent of PT-FI (subject to a dividend assignment mechanism to replicate the Joint Venture economics), and our ownership will be 48.8 percent. The transaction is expected to close in late 2018 or early 2019, subject to satisfaction of certain conditions.

OUTLOOK

We continue to 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 fluctuated historically and are affected by numerous factors beyond our control. Refer to “Markets” for further discussion. 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.

Projections for 2018 and other forward looking statements in this quarterly report on Form 10-Q assume extension of PT-FI’s long-term mining rights or an extension of PT-FI’s temporary special mining license (IUPK) after November 30, 2018. Refer to Note 8 for further discussion of Indonesia regulatory matters. For other important factors that could cause results to differ materially from projections, refer to “Cautionary Statement.”

Consolidated Sales Volumes

Following are our projected consolidated sales volumes for the year 2018 :



Copper (millions of recoverable pounds):
North America copper mines	1,421
South America mining	1,232
Indonesia mining	1,163
Total	3,816

Gold (thousands of recoverable ounces)	2,453

Molybdenum (millions of recoverable pounds)	95	^a


a.	Projected molybdenum sales include 35 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-quarter 2018 are expected to approximate 790 million pounds of copper, 330 thousand ounces of gold and 25 million pounds of molybdenum.

Consolidated Unit Net Cash Costs

Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices, primarily for gold and molybdenum. Assuming average prices of $1,200 per ounce of gold and $12.00 per pound of molybdenum for fourth-quarter 2018 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 $1.06 per pound of copper for the year 2018 . The impact of price changes for fourth-quarter 2018 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. 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 $2.85 per pound of copper, $1,200 per ounce of gold and $12.00 per pound of molybdenum for fourth-quarter 2018 , our consolidated operating cash flows are estimated to approximate $4.2 billion for the year 2018 (net of $0.5 billion in working capital uses and timing of other tax payments). Projected consolidated operating cash flows for the year 2018 also reflect an estimated income tax provision of $1.8 billion (refer to “Consolidated Results – Income Taxes” for further discussion of our projected income tax rate for the year 2018 ). The impact of price changes during fourth-quarter 2018 on operating cash flows would approximate $105 million for each $0.10 per pound change in the average price of copper, $15 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.

Table of Contents

Consolidated Capital Expenditures

Consolidated capital expenditures are expected to approximate $2.0 billion for the year 2018 , including $1.2 billion for major mining projects primarily associated with underground development activities in the Grasberg minerals district and development of the Lone Star oxide project.

MARKETS

World prices for copper, gold and molybdenum can fluctuate significantly. During the period from January 2008 through September 2018 , the London Metal Exchange (LME) copper settlement 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 (LBMA) PM gold price fluctuated from a low of $713 per ounce in 2008 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, 2017 .

This graph presents LME copper settlement 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 2008 through September 2018 . 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 throughout 2017. During third-quarter 2018 , LME copper settlement prices ranged from a low of $2.64 per pound to a high of $2.99 per pound, averaged $2.77 per pound and settled at $2.80 per pound on September 30, 2018 . The LME copper settlement price was $2.75 per pound on October 31, 2018 .

Table of Contents

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 existing large mines’ output 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 LBMA PM gold prices from January 2008 through September 2018 . An improving economic outlook, stronger U.S. dollar and positive equity performance contributed to lower demand for gold since 2014. During third-quarter 2018 , LBMA PM gold prices ranged from a low of $1,178 per ounce to a high of $1,262 per ounce, averaged $1,213 per ounce, and closed at $1,187 per ounce on September 30, 2018 . The LBMA PM gold price was $1,215 per ounce on October 31, 2018 .

Table of Contents

This graph presents the Metals Week Molybdenum Dealer Oxide weekly average prices from January 2008 through September 2018 . Molybdenum prices declined beginning in mid-2014 because of weaker demand from global steel and stainless steel producers but have rebounded starting in 2016 with further improvement in late-2017 and early 2018 before a decline in second-quarter 2018 . During third-quarter 2018 , the weekly average price of molybdenum ranged from a low of $10.67 per pound to a high of $12.49 per pound, averaged $11.81 per pound, and was $11.76 per pound on September 30, 2018 . The Metals Week Molybdenum Dealer Oxide weekly average price was $12.03 per pound on October 31, 2018 .

Consolidated revenues - 2018 period	$	4,908		$	14,944

Sales Volumes. Consolidated copper and gold sales volumes increased in the 2018 periods, compared to the 2017 periods, primarily reflecting higher ore grades and operating rates in Indonesia. Consolidated molybdenum sales volumes in the 2018 periods approximated the 2017 periods.

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

Realized Prices. Our consolidated revenues can vary significantly as a result of fluctuations in the market prices of copper, gold and molybdenum. Third-quarter 2018 average realized prices, compared with third-quarter 2017 , were 5 percent lower for copper, 8 percent lower for gold and 34 percent higher for molybdenum, and average realized prices for the first nine months of 2018 , compared with the first nine months of 2017 , were 6 percent higher for copper, 1 percent lower for gold and 35 percent higher for molybdenum. Refer to “Markets” for further discussion.

As discussed below, substantially all of our copper concentrate and cathode sales contracts provide final copper pricing in a specified future month. We record revenues and invoice customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period until final pricing on the date of settlement. Average realized copper prices include net adjustments to current period provisionally priced copper sales totaling $18 million in third-quarter 2018 and $(172) million for the first nine months of 2018 , compared with $38 million in third-quarter 2017 and $194 million for the first nine months of 2017 . Refer to Notes 6 and 9 for a summary of total adjustments to prior period and current period provisionally priced sales.

Prior Period 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 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. Net adjustments to prior periods’ provisionally priced copper sales recorded in consolidated revenues totaled $(111) million in third-quarter 2018 and $(70) million for the first nine months of 2018 , compared with $95 million in third-quarter 2017 and $81 million for the first nine months of 2017 . Refer to Notes 6 and 9 for a summary of total adjustments to prior period and current period provisionally priced sales.

At September 30, 2018 , we had provisionally priced copper sales totaling 373 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $2.84 per pound, subject to final pricing

Table of Contents

over the next several months. We estimate that each $0.05 change in the price realized from the September 30, 2018 , provisional price recorded would have an approximate $11 million effect on our 2018 net income attributable to common stock. The LME copper price settled at $2.75 per pound on October 31, 2018 .

Purchased Copper. We purchase copper cathode primarily for processing by our Rod & Refining operations. Purchased copper volumes totaled 93 million pounds in third-quarter 2018 and 257 million pounds for the first nine months of 2018 , compared with 75 million pounds in third-quarter 2017 and 195 million for the first nine months of 2017 .

Atlantic Copper Revenues. Atlantic Copper revenues increased to $579 million in third-quarter 2018 , compared with $555 million in third-quarter 2017 , primarily reflecting higher gold sales volumes. Atlantic Copper revenues increased to $1.8 billion for the first nine months of 2018 , compared with $1.4 billion for the first nine months of 2017 , primarily reflecting higher copper and gold sales volumes.

Production and Delivery Costs

Consolidated production and delivery costs totaled $3.1 billion in third-quarter 2018 and $2.8 billion in third-quarter 2017 . Third-quarter 2018 included charges totaling $69 million associated with Cerro Verde’s new three-year CLA and third-quarter 2017 included charges totaling $216 million associated with disputed royalties at Cerro Verde for prior years. Excluding these amounts, higher consolidated production and delivery costs in third-quarter 2018 primarily reflect higher mining and milling costs in Indonesia and North America.

Consolidated production and delivery costs totaled $8.8 billion for the first nine months of 2018 and $7.5 billion for the first nine months of 2017 . The first nine months of 2018 included charges totaling $69 million associated with Cerro Verde’s new three-year CLA. The first nine months of 2017 included charges totaling $216 million associated with disputed royalties at Cerro Verde for prior years and charges totaling $112 million associated with workforce reductions at PT-FI. Excluding these amounts, higher consolidated production and delivery costs for the first nine months of 2018 primarily reflects higher mining and milling costs in North America, South America and Indonesia and higher purchases at our smelting and refining operations.

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 $1.73 per pound of copper in third-quarter 2018 and $1.70 per pound of copper for the first nine months of 2018 , compared with $1.56 per pound of copper in third-quarter 2017 and $1.59 per pound of copper for the first nine months of 2017 . Higher consolidated unit site production and delivery costs in the 2018 periods, compared with the 2017 periods, primarily reflect charges associated with Cerro Verde's new three-year CLA and higher mining and milling costs in North America and South America, partly offset by higher copper sales volumes at PT-FI. 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 mining operations. Consolidated depreciation, depletion and amortization (DD&A) totaled $458 million in third-quarter 2018 and $1.4 billion for the first nine months of 2018 , compared with $418 million in third-quarter 2017 and $1.3 billion for the first nine months of 2017 .

Selling, General and Administrative Expenses

Consolidated selling, general and administrative expenses totaled $101 million in third-quarter 2018 , $104 million in third-quarter 2017 , $341 million for the first nine months of 2018 and $362 million for the first nine months of 2017 .

Mining Exploration and Research Expenses

Consolidated exploration and research expenses for our mining operations totaled $27 million in both third-quarter 2018 and 2017 , $72 million for the first nine months of 2018 and $60 million for the first nine months of 2017 . Our mining exploration activities are generally associated with our existing mines, focusing on opportunities to expand reserves and resources to support development of additional future production capacity. A drilling program to further delineate the Lone Star resource continues to indicate significant additional mineralization in this district, with higher

Table of Contents

ore grades than our other North America copper mines. Exploration spending is expected to approximate $85 million for the year 2018 .

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 for environmental obligations and shutdown costs totaled $8 million in third-quarter 2018 , $72 million in third-quarter 2017 and $76 million for both the first nine months of 2018 and 2017 . Refer to Note 8 for further discussion.

Net Gain on Sales of Assets

Net gain on sales of assets totaled $70 million in third-quarter 2018 and $126 million for the first nine months of 2018 , primarily reflecting adjustments to assets held for sale and to the fair value of the potential contingent consideration related to the 2016 sale of onshore California oil and gas properties. Potential contingent consideration related to this transaction consists of $50 million per year for 2018, 2019 and 2020 if the price of Brent crude oil averages over $70 per barrel in each of these calendar years. The average Brent crude oil price for the first nine months of 2018 is above $70 per barrel.

Net gain on sales of assets totaled $33 million in third-quarter 2017 and $66 million for the first nine months of 2017 , primarily associated with oil and gas transactions.

Interest Expense, Net

Interest expense, net includes interest associated with disputed Cerro Verde royalties (refer to Note 8 for additional discussion) totaling $1 million in third-quarter 2018 , $7 million for the first nine months of 2018 and $141 million for the third quarter and first nine months of 2017 . Consolidated interest costs (before capitalization and excluding interest expense associated with disputed Cerro Verde royalties) totaled $166 million in third-quarter 2018 , $196 million in third-quarter 2017 , $501 million for the first nine months of 2018 and $583 million for the first nine months of 2017 . Lower interest costs in the 2018 periods, compared with the 2017 periods, reflect 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 $24 million in third-quarter 2018 , $33 million in third-quarter 2017 , $72 million for the first nine months of 2018 and $91 million for the first nine months of 2017 .

Income Taxes

Following is a summary of the approximate amounts used in the calculation of our consolidated income tax provision (in millions, except percentages):

c.	Reflects tax charges of $127 million for disputed royalties and other related mining taxes for the period October 2011 through the year 2013, 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.

Table of Contents


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

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 $2.85 per pound for copper, $1,200 per ounce for gold and $12.00 per pound for molybdenum for fourth-quarter 2018 , we estimate our consolidated effective tax rate for the year 2018 would approximate 37 percent , and would decrease with higher prices.

Net (Loss) Income from Discontinued Operations

Net (loss) income from discontinued operations of $(4) million in third-quarter 2018 , $3 million in third-quarter 2017 , $(19) million for the first nine months of 2018 and $50 million for the first nine months of 2017 , primarily reflected adjustments to the fair value of the potential $120 million contingent consideration related to the November 2016 sale of our interest in TFHL, which will continue to be adjusted through December 31, 2019.

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 72 percent undivided joint venture interest in Morenci using the proportionate consolidation method.

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 potential 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. An initial project to develop the Lone Star oxide ores commenced in first-quarter 2018, with first production expected by the end of 2020. Total capital costs, including mine equipment and pre-production stripping, are expected to approximate $850 million and will benefit from the utilization of existing infrastructure at the adjacent Safford operation. As of September 30, 2018 , approximately $200 million has been incurred for this project. Production from the Lone Star oxide ores is expected to average approximately 200 million pounds of copper per year with an approximate 20-year mine life. The project also advances exposure to a significant sulfide resource. We continue to advance drilling activities to define future large-scale development opportunities in the Lone Star/Safford minerals district.

For further discussion of the risks associated with development projects, refer to Part I, Item 1A. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2017 , as updated in our subsequent quarterly reports on Form 10-Q.

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

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 $1.82 per pound of copper in third-quarter 2018 and $1.79 for the first nine months of 2018 were higher than unit net cash costs of $1.59 per pound in third-quarter 2017 and $1.52 for the first nine months of 2017 , primarily reflecting higher mining and milling costs and increased mining rates.

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.

America’s average unit net cash costs for the year 2018 would change by approximately $0.01 per pound for each $2 per pound change in the average price of molybdenum for fourth-quarter 2018 .

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), which 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.

In August 2018, Cerro Verde and its workers’ union agreed to a new three year CLA effective September 1, 2018.

Operating and Development Activities. Cerro Verde’s expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. The Cerro Verde expansion project, which achieved capacity operating rates in early 2016, expanded the concentrator facilities’ capacity from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day. During 2018, Cerro Verde received a modified environmental permit allowing it to operate its existing concentrator facilities at rates up to 409,500 metric tons of ore per day. Cerro Verde's concentrator facilities have continued to perform well, with average mill throughput rates of 384,800 metric tons of ore per day for the first nine months of 2018 .

We continue to evaluate a large-scale expansion at El Abra to process additional sulfide material and to achieve higher recoveries. El Abra’s large sulfide resource could potentially support a major mill project similar to facilities constructed at Cerro Verde. Technical and economic studies are being advanced to determine the optimal scope and timing for the project.

a.	Includes charges totaling $0.21 per pound of copper in third-quarter 2018 and $0.07 per pound of copper for the first nine months of 2018 associated with Cerro Verde’s new three-year CLA.


b.	Includes charges totaling $0.66 per pound of copper in third-quarter 2017 and $0.23 per pound of copper for the first nine months of 2017 associated with disputed Cerro Verde royalties for prior years.

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 $1.81 per pound of copper in third-quarter 2018 were higher than unit net cash costs of $1.64 per pound in third-quarter 2017 , primarily reflecting costs associated with Cerro Verde’s new three-year CLA. Average unit net cash costs (net of by-product credits) of $1.76 for the first nine months of 2018 were higher than unit net cash costs of $1.61 for the first nine months of 2017 , primarily reflecting costs associated with Cerro Verde’s new three-year CLA and higher mining and milling costs.

Revenues from Cerro Verde’s concentrate sales are recorded net of treatment charges, which 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 $1.73 per pound of copper for the year 2018 , based on current sales volume and cost estimates and assuming an average price of $12.00 per pound of molybdenum for fourth-quarter 2018 .

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-II. 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 2018 , approximately 40 percent of PT-FI’s concentrate production was sold to PT Smelting (PT-FI’s 25-percent-owned smelter and refinery in Gresik, Indonesia).

PT-FI currently operates a proportionately consolidated unincorporated joint venture with Rio Tinto (the Joint Venture), 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. After 2022, all production and related revenues and costs are shared 60 percent PT-FI and 40 percent Rio Tinto. Refer to Note 8 and below for discussion of the pending transaction in which PT Inalum will acquire all of Rio Tinto’s interest associated with the Joint Venture and 100 percent of our interests in PT-II.

Regulatory Matters. On September 27, 2018, we, PT-FI, PT-II and PT Inalum entered into a Divestment Agreement on previously agreed economic terms in connection with PT Inalum’s acquisition of shares of PT-FI. Under the Divestment Agreement, PT Inalum will acquire, for cash consideration of $350 million, 100 percent of our interests in PT-II, which owns 9.36 percent of PT-FI (equates to a 5.6 percent interest after 2022). PT Inalum also entered into a definitive agreement with Rio Tinto to acquire for cash consideration of $3.5 billion, all of Rio Tinto's interests (40 percent interest after 2022) associated with the Joint Venture.

The arrangements provide for us and existing PT-FI shareholders to retain the economics of the revenue and cost sharing arrangements under the Joint Venture and for us to continue to manage PT-FI's operations. Following completion of the transaction, PT-FI will have an expanded asset base as a result of Rio Tinto’s interests being merged into PT-FI, and PT Inalum's share ownership will be 51.2 percent of PT-FI (subject to a dividend assignment mechanism to replicate the Joint Venture economics), and our ownership will be 48.8 percent.

PT-FI has agreed to complete the construction of a smelter within five years of the closing, with economics shared pro rata by us and PT Inalum according to our respective equity ownership in PT-FI. Concurrent with the closing of the divestment transaction, PT-FI will be granted an IUPK providing long-term mining rights with assured legal and fiscal terms and legal enforceability through 2041. The IUPK issued at closing will initially be valid through 2031 a

Table of Contents

nd will include an assured extension through 2041 upon PT-FI’s satisfaction of agreed conditions, including those related to smelter construction and payment of state revenues in accordance with the IUPK.

The transaction, which is expected to close in late 2018 or early 2019, is subject to certain conditions, including the documentation and issuance by the Indonesian government of the IUPK providing for the extension and stability of PT-FI’s long-term mining rights with assured legal and fiscal terms and legal enforceability through 2041 in a form acceptable to us and PT Inalum; resolution of environmental regulatory matters that include amendments to the decrees imposing unattainable environmental standards on PT-FI pending before the Ministry satisfactory to the Indonesian government, us and PT Inalum; various other Indonesian regulatory actions and approvals, including modification or revocation of current regulations and implementation of new regulations by the Indonesian government and assurances or approvals by Indonesian tax authorities with respect to the pending transaction; and receipt of customary regulatory approvals from international competition authorities.

The Divestment Agreement provides us and PT Inalum with the right to terminate, in certain circumstances, including if the transaction is not consummated on or before December 31, 2018, subject to a six month extension if needed, to obtain regulatory approvals from international competition authorities.

PT-FI's export license is effective through February 15, 2019, and PT-FI's temporary IUPK is effective through November 30, 2018. PT-FI will continue to seek extensions to its temporary IUPK until closing of the pending transaction. Until the pending transaction is completed, PT-FI has reserved all rights under its Contract of Work (COW).

For further discussion of the regulatory matters and risks associated with operations in Indonesia, refer to Part I, Item IA. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2017 , as updated in our subsequent quarterly reports on Form 10-Q.

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. Following results of an economic analysis in the first half of 2018, PT-FI revised its mine plans to continue to mine ore from the open pit until transitioning to the Grasberg Block Cave (GBC) underground mine in the first half of 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.

PT-FI’s estimated annual capital spending on underground mine development projects is expected to average $0.8 billion per year ( $0.7 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.

As discussed above, PT-FI is also evaluating plans for the development of a new copper smelter in Indonesia, including site selection, engineering, joint venture and financing arrangements.

The following provides additional information on the continued development of the Common Infrastructure project, the GBC underground mine and the Deep Mill Level Zone (DMLZ) ore body that lies below the 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, which will be replaced by the IUPK upon completion of the pending transaction.

Common Infrastructure and GBC Underground 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 was on care-and-maintenance status during most of 2017 and production restarted in fourth-

Table of Contents

quarter 2017. Development of the GBC and DMLZ underground mines is advancing using the Common Infrastructure project tunnels as access.

The GBC underground mine accounts for approximately half of our recoverable proven and probable reserves in Indonesia. Substantial progress has been made to prepare for the transition to mining of the GBC underground mine. First undercut blasting occurred in September 2018, and cave production is scheduled for the first half of 2019. All underground mining levels and the ore flow system are being commissioned. Production rates over the next five years are expected to ramp up to 130,000 metric tons of ore per day.

Aggregate mine development capital for the GBC underground mine and associated Common Infrastructure is expected to approximate $6.4 billion (incurred between 2008 and 2023), with PT-FI’s share totaling approximately $5.9 billion. Aggregate project costs totaling $3.8 billion have been incurred through September 30, 2018 , including $0.5 billion during the first nine months of 2018 .

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 represented ore extracted during the development phase for the purpose of obtaining access to the ore body. During second-quarter 2018, PT-FI initiated plans to conduct hydraulic fracturing activities to manage rock stresses and pre-condition the DMLZ underground mine for large-scale production following mining induced seismic activity experienced in 2017 and 2018. Hydraulic fracturing activities designed to safely manage production commenced in third-quarter 2018 and, to date, have produced the expected effective results. PT-FI’s revised mine plans for the DMLZ underground mine, which continue to be reviewed, currently project block cave mining activities in the DMLZ underground mine to commence in mid-2019. PT-FI expects the DMLZ underground mine to reach full production rates of 80,000 metric tons per day in 2022. Estimates of timing of future production continue to be reviewed and may be modified as additional information becomes available.

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 $3.1 billion (incurred between 2009 and 2021), with PT-FI’s share totaling approximately $1.9 billion. Aggregate project costs totaling $2.4 billion have been incurred through September 30, 2018 , including approximately $0.3 billion during the first nine months of 2018 .

Other Matters. 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, 2017 , there have been a series of shooting incidents within the PT-FI project area and in nearby areas. During the first nine months of 2018 , there were 12 additional shooting incidents, which resulted in 5 injuries. The safety of our workforce is a critical concern, and PT-FI continues to work 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.

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.

Indonesia mining’s consolidated sales of 368 million pounds of copper and 831 thousand ounces of gold in third-quarter 2018 and 1.0 billion pounds of copper and 2.1 million ounces of gold for the first nine months of 2018 were higher than sales of 258 million pounds of copper and 352 thousand ounces of gold in third-quarter 2017 and 630 million pounds of copper and 956 thousand ounces of gold for the first nine months of 2017 , primarily reflecting higher operating rates and ore grades.

Assuming achievement of planned operating rates for fourth-quarter 2018 , consolidated sales volumes from Indonesia mining are expected to approximate 1.16 billion pounds of copper and 2.45 million ounces of gold for the year 2018 , compared with 1.0 billion pounds of copper and 1.5 million ounces of gold for the year 2017 .

As PT-FI transitions mining from the open pit to underground, its production is expected to be significantly lower in 2019 and 2020, compared to 2018. Metal production is expected to improve significantly by 2021 following a ramp-up period.

Indonesia mining's projected sales volumes and unit net cash credits for the year 2018 are dependent on a number of factors, including operational performance, workforce productivity, timing of shipments, and Indonesia regulatory matters, including extension of PT-FI's long-term mining rights or an extension of PT-FI's temporary IUPK after November 30, 2018.

a.	Includes fixed costs charged directly to production and delivery costs totaling $0.03 per pound of copper in third-quarter 2017 and $0.18 per pound of copper for the first nine months of 2017 associated with workforce reductions.

Table of Contents

A significant portion of PT-FI’s costs are fixed and unit costs vary depending on production volumes and other factors. As a result of higher sales volumes and gold and silver credits, Indonesia had unit net cash credits (including gold and silver credits) of $0.72 per pound of copper in third-quarter 2018 and $0.71 per pound of copper for the first nine months of 2018 , compared with unit net cash costs of $0.13 per pound of copper in third-quarter 2017 and $0.25 per pound of copper for the first nine months of 2017 .

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.

Because certain assets are depreciated on a straight-line basis, PT-FI’s unit depreciation rate varies with the level of copper production.

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

Because of the fixed nature of a large portion of Indonesia’s costs, unit net cash credits/costs vary from quarter to quarter depending on copper and gold volumes. Assuming an average gold price of $1,200 per ounce for fourth-quarter 2018 and achievement of current sales volume and cost estimates, unit net cash credits (including gold and silver credits) for Indonesia mining are expected to approximate $0.54 per pound of copper for the year 2018 . Indonesia mining’s unit net cash credits for the year 2018 would change by approximately $0.03 per pound for each $50 per ounce change in the average price of gold for the fourth-quarter 2018 . As a result of lower expected copper and gold production during the transition from the open pit to the GBC underground mine, Indonesia mining's unit net cash costs are expected to be higher in 2019 and 2020.

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. Production from the Molybdenum mines totaled 8 million pounds of molybdenum in both third-quarter 2018 and 2017 , 26 million pounds for the first nine months of 2018 and 24 million pounds for the first nine months of 2017 . 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 $9.02 per pound of molybdenum in third-quarter 2018 and $8.64 per pound of molybdenum for the first nine months of 2018 were higher than average unit costs of $7.82 per pound of molybdenum in third-quarter 2017 and $7.52 per pound of molybdenum for the first nine months of 2017 , primarily reflecting higher operating rates and costs associated with ramp-up activity. Based on current sales volume and cost estimates, average unit net cash costs for the Molybdenum mines are expected to approximate $8.80 per pound of molybdenum for the year 2018 . 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), a refinery in Texas (El Paso refinery) 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 and El Paso refinery. 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 2018 , Atlantic Copper’s concentrate purchases from our copper mining operations included 13 percent from our North America copper mines, 6 percent from our South America copper mining operations and 3 percent from our Indonesia mining operations, with the remainder purchased from third parties.

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 2018 , PT-FI supplied all of PT Smelting’s concentrate requirements.

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 (reductions) additions to net income attributable to common stock of $(24) million in third-quarter 2018 , $24 million in third-quarter 2017 , $(4) million for the first nine months of 2018 and less than $1 million for the first nine months of 2017 . 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 $85 million at September 30, 2018 . 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 prices realized from copper, gold and molybdenum; our sales volumes; 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 have commenced a project to develop the Lone Star oxide ores near the Safford operation in eastern Arizona, and 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. We are also pursuing other opportunities to enhance 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, 2018 (in billions):



Cash at domestic companies	$	2.7
Cash at international operations	1.9
Total consolidated cash and cash equivalents	4.6
Noncontrolling interests’ share	(0.5		)
Cash, net of noncontrolling interests’ share	4.1
Withholding taxes and other	(0.1		)
Net cash available	$	4.0

Cash held at our international operations is generally used to support our foreign operations’ capital expenditures, operating expenses, debt repayment, 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

Table of Contents

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, 2018 (in billions, except percentages):



			Weighted-
			Average
			Interest Rate
Senior Notes	$	9.9	4.6%
Cerro Verde credit facility	1.2		4.1%
Total debt	$	11.1	4.5%

At September 30, 2018 , we had no borrowings, $13 million in letters of credit issued and availability of $3.5 billion under our revolving credit facility, which matures on April, 20, 2023.

Refer to Note 5 for further discussion of debt.

Operating Activities

We generated consolidated operating cash flows of $3.9 billion (net of $0.2 billion in working capital uses and timing of other tax payments) for the first nine months of 2018 and $3.0 billion (including $0.4 billion in working capital sources and timing of other tax payments) for the first nine months of 2017 . Higher operating cash flows for the first nine months of 2018 , compared to the first nine months of 2017 , primarily reflect higher copper and gold sales volumes and higher copper prices.

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

Investing Activities

Capital Expenditures. Capital expenditures, including capitalized interest, totaled $1.4 billion for the first nine months of 2018 , including $0.9 billion for major mining projects. Capital expenditures, including capitalized interest, totaled $1.0 billion for the first nine months of 2017 , including $0.6 billion for major mining projects. Higher capital expenditures for the first nine months of 2018 , compared with the first nine months of 2017 , primarily reflect increased spending on major mining projects mostly associated with development of the Lone Star oxide project. Refer to “Outlook” for further discussion of projected capital expenditures for the year 2018 .

Financing Activities

Debt Transactions. Net repayments of debt for the first nine months of 2018 totaled $1.9 billion , primarily consisting of $1.4 billion for senior notes due March 2018 and $454 million for senior notes due in 2022 and 2023. Refer to Note 5 for further discussion.

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.

Dividends. In February 2018, the Board reinstated a cash dividend on our common stock. We paid dividends on our common stock totaling $145 million for the first nine months of 2018 . On September 26, 2018, FCX declared a quarterly cash dividend of $0.05 per share, which was paid November 1, 2018, to shareholders of record as of October 15, 2018. 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.

PRODUCT REVENUES AND PRODUCTION COSTS

Unit net cash costs (credits) 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 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 (credits), 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, expectations related to the pending transaction between us, PT-FI, PT-II and PT Inalum, including, but not limited to, replication of the economics of the revenue and cost sharing arrangements under the Joint Venture pursuant to a dividend assignment mechanism, our continued management of PT-FI’s operations, the expected timing of completion of the pending transaction, 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. The declaration of dividends is at the discretion of the Board and will depend on our financial results, cash requirements, future prospects, and other factors deemed relevant by the Board.

We caution readers that forward-looking statements are not guarantees of future performance and actual results may differ materially from those anticipated, expected, 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, but are not limited to, supply of and demand for, and prices of, copper, gold and molybdenum; mine sequencing; production rates; potential inventory adjustments; potential impairment of long-lived mining assets; the ability to satisfy conditions to close the pending PT-FI transaction, including, but not limited to, the documentation and issuance by the Indonesian government of an IUPK providing for the extension and stability of PT-FI’s long-term mining rights with assured legal and fiscal terms and legal enforceability through 2041 in a form acceptable to us and PT Inalum, resolution of environmental regulatory matters that include amendments satisfactory to us, the Indonesian government and PT Inalum, various other Indonesian regulatory actions and approvals, including modification or revocation of current regulations and the implementation of new regulations by the Indonesian government and assurances or approvals by Indonesian tax authorities with respect to the pending transaction and receipt of customary regulatory approvals from international competition authorities; obtaining an extension of PT-FI’s temporary IUPK after November 30, 2018; the potential effects of violence in Indonesia generally and in the province of Papua; industry risks; regulatory changes; political risks; labor relations; weather- and climate-related risks; environmental risks; litigation results (including 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, 2017 , and Part II, Item 1A. “Risk Factors” of our subsequent quarterly reports on Form 10-Q, filed with the SEC.

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, 2018 . 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, 2017 . 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, 2018 ; for projected sensitivities of our provisionally priced copper sales 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, 2018 .


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, 2018 .


(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, 2018 , 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 our annual report on Form 10-K for the year ended December 31, 2017 , as updated in our subsequent filings, 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.

Item 1A. Risk Factors.

The following updates the risk factor titled “ Development projects are inherently risky and may require more capital than anticipated, which could adversely affect our business ,” which was included in our annual report on Form 10-K for the year ended December 31, 2017, and was amended and restated in our quarterly report on Form 10-Q for the quarter ended June 30, 2018:

Development projects are inherently risky and could require more time and capital than anticipated, which could adversely affect our business.

Currently, our major mining projects include underground development activities in the Grasberg minerals district and development of the Lone Star oxide project in Arizona. There are many risks and uncertainties inherent in all development projects including, but not limited to, unexpected or difficult geological formations or conditions, potential delays, cost overruns, shortages of material or labor, construction defects, breakdowns and injuries to persons and property. The development of our underground mines and operations are also subject to other unique risks including, but not limited to, underground fires or floods, ventilating harmful gases, fall-of-ground accidents, and seismic activity resulting from unexpected or difficult geological formations or conditions. While we anticipate taking all measures that we deem reasonable and prudent in connection with the development of our underground mines to safely manage production, there is no assurance that these risks will not cause schedule delays, revised mine plans, injuries to persons and property, or increased capital costs, any of which may have a material adverse impact on our cash flows, results of operations and financial condition. Additionally, although we devote significant

Table of Contents

time and resources to our project planning, approval and review processes, many of our development projects are highly complex and rely on factors that are outside of our control, which may cause us to underestimate the time and capital required to complete a development project.

In September 2015, we initiated pre-commercial production at the Deep Mill Level Zone (DMLZ) underground mine.

During second-quarter 2018, PT Freeport Indonesia (PT-FI) initiated plans to conduct hydraulic fracturing activities to manage rock stresses and pre-condition the DMLZ underground mine for large-scale production following mining induced seismic activity experienced in 2017 and 2018. Hydraulic fracturing activities designed to safely manage production commenced in third-quarter 2018. PT-FI’s revised mine plans for the DMLZ underground mine, which continue to be reviewed, currently project block cave mining activities in the DMLZ underground mine to commence in mid-2019. PT-FI expects the DMLZ to reach full production rates of 80,000 metric tons per day in 2022. Estimates of timing of future production continue to be reviewed and may be modified as additional information becomes available.

In addition, the economic feasibility of development projects is based on many factors, including the accuracy of estimated reserves, estimated capital and operating costs, and estimated future prices of the relevant commodity. Consolidated capital expenditures are expected to approximate $2.0 billion for the year 2018, including $1.2 billion for major mining projects primarily associated with underground development activities in the Grasberg minerals district and development of the Lone Star oxide project. Refer to the risk factor “Because our Grasberg mining operation in Indonesia is a significant operating asset, our business may continue to be adversely affected by political, economic and social uncertainties in Indonesia” for further discussion of regulatory matters in Indonesia that may impact future investments in PT-FI’s underground development projects. The capital expenditures and time required to develop new mines or other projects are considerable, and changes in costs or timing can adversely affect project economics.

New development projects have no operating history upon which to base estimates of future cash flow. The actual costs, production rates and economic returns of our development projects may differ materially from our estimates, which may have a material adverse impact on our cash flows, results of operations and financial condition.

Except as described above, there have been no material changes to our risk factors during the nine-month period ended September 30, 2018. For additional information on risk factors, refer to Part I, Item 1A. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2017 .


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, 2018 .

There were no shares of common stock purchased by us during the three months ended September 30, 2018 . 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, 2018 , 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.
