NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
NOTE 1. GENERAL INFORMATION
The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by generally accepted accounting principles (GAAP) in the United States (U.S.). Therefore, this information should be read in conjunction with Freeport-McMoRan Inc.’s (FCX) consolidated financial statements and notes contained in its annual report on Form 10-K for the year ended December 31, 2018 (2018 Form 10-K). 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. All such adjustments are, in the opinion of management, of a normal recurring nature, except for the adjustment discussed in Note 12. Operating results for the nine-month period ended September 30, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.
Property, Plant, Equipment and Mine Development Costs. The following is an update to FCX’s property, plant, equipment and mine development costs accounting policy included in Note 1 of its 2018 Form 10-K. Development costs are capitalized beginning after proven and probable mineral reserves have been established. Development costs include costs incurred resulting from mine pre-production activities undertaken to gain access to proven and probable reserves, including shafts, adits, drifts, ramps, permanent excavations, infrastructure and removal of overburden. For underground mines certain costs related to panel development, such as undercutting and drawpoint development, are also capitalized as mine development costs until production reaches design capacity for the mine. After reaching design capacity, the mine transitions to the production phase and panel development costs are allocated to inventory and then included as a component of cost of goods sold.
Attribution of PT Freeport Indonesia (PT-FI) Net Income or Loss. FCX has concluded that the attribution of PT-FI’s net income or loss from the date of the divestment transaction (i.e., December 21, 2018) through December 31, 2022 (the Initial Period), should be based on the economics replacement agreement, which provides for FCX and the other pre-transaction PT-FI shareholders (i.e., PT Indonesia Asahan Aluminium (Persero) (PT Inalum) and PT Indonesia Papua Metal Dan Mineral (PTI)) to retain the economics of the revenue and cost sharing arrangements under PT-FI’s joint venture formerly with Rio Tinto Plc (refer to Note 2 of FCX’s 2018 Form 10-K). The economics replacement agreement entitles FCX to approximately 81 percent of PT-FI dividends paid during the Initial Period, with the remaining 19 percent paid to the noncontrolling interests. PT-FI’s net loss in third-quarter 2019 totaled $24 million, of which $20 million was attributed to FCX, and for the first nine months of 2019 totaled $28 million, of which $23 million was attributed to FCX. PT-FI’s cumulative net loss since the December 21, 2018, transaction date through September 30, 2019, totaled $164 million, of which $133 million was attributed to FCX.
The above-described attribution of PT-FI’s net income or loss applies only through the Initial Period. Beginning January 1, 2023, the attribution of PT-FI’s net income or loss will be based on equity ownership percentages (48.76 percent for FCX, 26.24 percent for PT Inalum and 25.00 percent for PTI). For all of its other partially owned consolidated subsidiaries, FCX attributes net income or loss based on equity ownership percentages.
Agreement to Sell a Portion of Cobalt Business. In second-quarter 2019, FCX entered into an agreement to sell its cobalt refinery in Kokkola, Finland, and related cobalt cathode precursor business (consisting of approximately $201 million of assets and $76 million of liabilities at September 30, 2019) for total consideration of approximately $150 million, plus working capital at the time of closing. FCX and the current noncontrolling interest partners in Freeport Cobalt will retain the remaining cobalt business, which is a producer of cobalt fine powders, chemicals, catalysts, ceramics and pigments. The transaction is expected to close by year-end 2019. Lundin Mining Corporation, which is one of the noncontrolling interest partners, is entitled to receive 30 percent of the proceeds from this transaction. In addition to customary closing conditions, including regulatory approvals, prior to completing the transaction, Freeport Cobalt is required to be segregated into two separate businesses.

NOTE 2. EARNINGS PER SHARE
FCX calculates its basic net (loss) income per share of common stock under the two-class method and calculates its diluted net (loss) income per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net (loss) income per share of common stock was computed by dividing net (loss) income attributable to common stockholders by the weighted-average shares of common stock outstanding during the period. Diluted net (loss) 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.
Reconciliations of net (loss) income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted net (loss) income per share follow (in millions, except per share amounts):

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 (loss) income per share of common stock. Stock options for 43 million shares of common stock in third-quarter 2019, 38 million shares in third-quarter 2018, 42 million shares for the first nine months of 2019 and 35 million shares for the first nine months of 2018 were excluded.

Leach stockpiles | 1,077 |  |  | 1,049 |  |
Total long-term mill and leach stockpiles b | $ | 1,300 |  |  | $ | 1,314 |  |

a. | Materials and supplies inventory was net of obsolescence reserves totaling $26 million at September 30, 2019, and $24 million at December 31, 2018.

b. | Estimated metals in stockpiles not expected to be recovered within the next 12 months.

FCX recorded charges of $41 million in third-quarter 2019, primarily for copper inventories, and $100 million for the first nine months of 2019, primarily for cobalt inventories ($58 million) and copper inventories ($41 million), to adjust metals inventory carrying values to net realizable value because of lower market prices (refer to Note 9 for metals inventory adjustments by business segment).
NOTE 4. INCOME TAXES
Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. Geographic sources of FCX’s benefit from (provision for) income taxes follow (in millions):

| Nine Months Ended |
| September 30, |
| 2019 |  | 2018 |
U.S. operations | $ | 73 |  | a | $ | 2 |  |
International operations | (254 | ) |  | (1,545 | ) |
Total | $ | (181 | ) | b | $ | (1,543 | ) |

a. | Includes tax credits totaling $24 million primarily associated with state law changes and settlement of state income tax examinations.

b. | Includes net tax charges totaling $49 million primarily to adjust deferred taxes on historical balance sheet items in accordance with tax accounting principles.

FCX’s consolidated effective income tax rate was 302 percent for the first nine months of 2019 and was 38 percent for the first nine months of 2018. FCX's consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which FCX operates. Because FCX's U.S. jurisdiction generated net losses in the first nine months of 2019 that will not result in a realized tax benefit, applicable accounting rules require FCX to adjust its estimated annual effective tax rate to exclude the impact of U.S. net losses.

NOTE 5. DEBT AND EQUITY
The components of debt follow (in millions):

|  | September 30, 2019 |  | December 31, 2018
Senior notes and debentures: |  |  |  |
Issued by FCX |  | $ | 8,600 |  |  | $ | 9,594 |
Issued by Freeport Minerals Corporation (FMC) |  | 357 |  |  | 358 |

Total debt |  | 9,919 |  |  | 11,141 |
Less current portion of debt |  | (4 | ) |  | (17 | )
Long-term debt |  | $ | 9,915 |  |  | $ | 11,124 |

Revolving Credit Facility. At September 30, 2019, FCX had no borrowings outstanding and $13 million in letters of credit issued under its 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.
On May 2, 2019, FCX’s $3.5 billion revolving credit facility was amended to extend $3.26 billion of the facility by one year to April 20, 2024. The remaining $240 million matures on April 20, 2023. In addition, the revolving credit facility was amended to modify the calculation of the total debt component used to determine the total leverage ratio by increasing the amount of unrestricted cash that may be applied to reduce the amount of total debt. There were no other substantive modifications to the revolving credit facility.
Senior Notes. On March 27, 2019, FCX redeemed all of its outstanding $1.0 billion aggregate principal amount of 3.100% Senior Notes due 2020. Holders of these senior notes received the principal amount together with the redemption premium and accrued and unpaid interest up to the redemption date. As a result of this redemption, FCX recorded a loss on early extinguishment of debt totaling $5 million in first-quarter 2019.
On August 15, 2019, FCX completed the sale of $600 million of 5.00% Senior Notes due 2027 and $600 million of 5.25% Senior Notes due 2029 for total net proceeds of $1.187 billion. Interest on these senior notes is payable semiannually on March 1 and September 1 of each year. These senior notes rank equally with FCX’s other existing and future unsecured and unsubordinated indebtedness. FCX used the net proceeds from this offering to fund the make-whole redemption of all of its outstanding 6.875% Senior Notes due 2023, and the concurrent tender offers to purchase a portion of its 4.00% Senior Notes due 2021 and its 3.55% Senior Notes due 2022, and the payment of accrued and unpaid interest, premiums, fees and expenses in connection with these transactions. As a result of these transactions, FCX recorded a loss on early extinguishment of debt totaling $21 million in third-quarter 2019 as follows (in millions):

| Principal Amount |  | Net Adjustments |  | Book Value |  | Redemption/Tender Value |  | Loss
FCX 6.875% Senior Notes due 2023 | $ | 728 |  |  | $ | 34 |  |  | $ | 762 |  |  | $ | 768 |  |  | $ | 6 |
FCX 4.00% Senior Notes due 2021 | 405 |  |  | (2 | ) |  | 403 |  |  | 418 |  |  | 15 |
FCX 3.55% Senior Notes due 2022 | 12 |  |  | — |  |  | 12 |  |  | 12 |  |  | — |
| $ | 1,145 |  |  | $ | 32 |  |  | $ | 1,177 |  |  | $ | 1,198 |  |  | $ | 21 |

Cerro Verde Credit Facility. In March 2019, Cerro Verde prepaid $200 million on its credit facility, which resulted in a $1 million loss on early extinguishment of debt in first-quarter 2019.
Interest Expense, Net. Consolidated interest costs (before capitalization) totaled $163 million in third-quarter 2019, $167 million in third-quarter 2018, $508 million for the first nine months of 2019 and $508 million for the first nine months of 2018. Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $40 million in third-quarter 2019, $24 million in third-quarter 2018, $107 million for the first nine months of 2019 and $72 million for the first nine months of 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, 2019, and December 31, 2018, FCX had no price protection contracts relating to its mine production. A discussion of FCX’s derivative contracts and programs follows.
Derivatives Designated as Hedging Instruments – Fair Value Hedges
Copper Futures and Swap Contracts. Some of FCX’s U.S. copper rod customers request a fixed market price instead of the Commodity Exchange Inc. (COMEX) average copper price in the month of shipment. FCX hedges this price exposure in a manner that allows it to receive the COMEX average price in the month of shipment while the customers pay the fixed price they requested. FCX accomplishes this by entering into copper futures or swap contracts. Hedging gains or losses from these copper futures and swap contracts are recorded in revenues. FCX did not have any significant gains or losses resulting from hedge ineffectiveness during the nine-month periods ended September 30, 2019 and 2018. At September 30, 2019, FCX held copper futures and swap contracts that qualified for hedge accounting for 72 million pounds at an average contract price of $2.66 per pound, with maturities through August 2021.
A summary of (losses) gains 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, copper cathode and gold sales contracts provide for provisional pricing primarily based on the London Metal Exchange (LME) copper price or the COMEX copper price and the London Bullion Market Association (LBMA) gold price at the time of shipment as specified in the contract. FCX receives market prices based on prices in the specified future month, which results in price fluctuations recorded in revenues until the date of settlement. FCX records revenues and invoices customers at the time of shipment based on then-current LME or COMEX copper prices and the LBMA gold prices as specified in the contracts, which results in an embedded derivative (i.e., a pricing mechanism that is finalized after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale of the metals contained in the concentrate or cathode at the then-current LME or COMEX copper price, and the LBMA gold price. FCX applies the normal purchases and normal sales scope exception in accordance with derivatives and hedge accounting guidance to the host contract in its concentrate or cathode sales agreements since these contracts do not allow for net settlement and always result in physical delivery. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through earnings each period, using the period-end LME or COMEX copper forward prices and the adjusted LBMA gold prices, until the date of final pricing. Similarly, FCX purchases copper and cobalt under contracts that provide for provisional pricing. 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.

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, 2019, Atlantic Copper held net copper forward purchase contracts for 1 million pounds at an average contract price of $2.65 per pound, with maturities through November 2019.

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.

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, 2019, the maximum amount of credit exposure associated with derivative transactions was $5 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 $1.3 billion at September 30, 2019, and $2.3 billion at December 31, 2018), 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, 2019, FCX has contingent consideration assets related to the 2016 asset sales of TF Holdings Limited (TFHL), onshore California oil and gas properties and Deepwater Gulf of Mexico (GOM) oil and gas properties (refer to Note 7 for the related fair values and to Note 2 of FCX’s 2018 Form 10-K for further discussion of these instruments).

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 2019.
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 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):

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).
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.
17

Table of Contents
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.
Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.
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. FCX’s embedded derivatives on provisional cobalt purchases 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. As a result, these derivatives are classified within Level 2 of the fair value hierarchy.
FCX’s derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 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 2018 Form 10-K, 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. The fair value of the contingent consideration derivative associated with the sale of TFHL was $59 million at September 30, 2019 (included in other current assets in the consolidated balance sheet), and $57 million at December 31, 2018 (included in other assets). Future changes in the fair value of this contingent consideration derivative will continue to be recorded in discontinued operations. Also in 2016, FCX’s 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. The fair value of the contingent consideration derivative (included in other assets in the consolidated balance sheets) associated with the sale of the onshore California oil and gas properties was $8 million at September 30, 2019, and $16 million at December 31, 2018. Future changes in the fair value of this contingent consideration derivative will continue to be recorded in operating income. Also, contingent consideration of $50 million associated with the onshore California oil and gas properties was realized in 2018 and collected in first-quarter 2019 (included in proceeds from sales of oil and gas properties in the consolidated statements of cash flows) because the average Brent crude oil price exceeded $70 per barrel for 2018 and was included in other current assets in the consolidated balance sheet at December 31, 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.
As reported in Note 2 of FCX’s 2018 Form 10-K, in December 2016, FCX’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 $18 million at September 30, 2019, and $27 million at December 31, 2018, and (ii) other assets totaled $110 million at September 30, 2019, and $116 million at December 31, 2018. 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.
18

Table of Contents
Long-term debt, including current portion, is primarily 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 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, 2019, as compared with those techniques used at December 31, 2018.
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 2019 follows (in millions):

Fair value at January 1, 2019 | $ | 127 |  |
Net unrealized loss related to assets still held at the end of the period | (1 | ) |
Settlements | (16 | ) |
Fair value at September 30, 2019 | $ | 110 |  |

NOTE 8. CONTINGENCIES AND COMMITMENTS
Litigation
Louisiana Parishes Coastal Erosion Cases. In September 2019, affiliates of FCX reached an agreement in principle to settle all 13 cases filed in Louisiana state courts by six south Louisiana parishes (Cameron, Jefferson, Plaquemines, St. Bernard, St. John the Baptist and Vermilion) and the parties that have intervened in the litigation, including the state of Louisiana, through the Attorney General and separately through the Louisiana Department of Natural Resources in support of the parishes’ claims, alleging that certain oil and gas exploration and production operations and sulphur mining and production operations of the FCX affiliates damaged coastal wetlands and caused significant land loss along the Louisiana coast.
The maximum out-of-pocket settlement payment will be $23.5 million with the initial payment of $15 million to be paid upon execution of the settlement agreement. The initial payment will be held in trust and later deposited into a newly formed Coastal Zone Recovery Fund (the Fund) once the state of Louisiana passes enabling legislation to establish the Fund. The settlement agreement will also require the FCX affiliates to pay into the Fund twenty annual installments of $4.25 million beginning in 2023 provided the state of Louisiana passes the enabling legislation. The first two of those annual installments are conditioned only on the enactment of the enabling legislation within three years of execution of the settlement agreement, but all subsequent installments are also conditioned on the FCX affiliates receiving simultaneous reimbursement on a dollar-for-dollar basis from the proceeds of environmental credit sales generated by the Fund, resulting in the $23.5 million maximum total payment obligation. The settlement agreement is currently expected to be executed during fourth-quarter 2019 and will need to be executed by all parties, including authorized representatives of the six south Louisiana parishes originally plaintiffs in the suit and certain other non-plaintiff Louisiana parishes and the state of Louisiana. Upon execution of the settlement agreement, the FCX affiliates will be fully released and dismissed from all 13 pending cases. The agreement in principle does not include any admission of liability by FCX or its affiliates. FCX recorded a charge in third-quarter 2019 for the initial payment of $15 million, which will be paid upon execution of the settlement agreement.
There were no significant updates to previously reported legal proceedings included in Note 12 of FCX’s 2018 Form 10-K, other than the asbestos and talc claims matter below, which was updated in Note 8 of FCX’s quarterly report on Form 10-Q for the quarters ended March 31, 2019, and June 30, 2019, and below.
Asbestos and Talc Claims. As previously disclosed, there has been a significant increase in the number of cases alleging the presence of asbestos contamination in talc-based personal care products and in cases alleging exposure to talc products that are not alleged to be contaminated with asbestos. The primary targets have been the producers of those products, but defendants in many of these cases also include talc miners. Cyprus Amax Minerals Company (CAMC), an indirect wholly owned subsidiary of FCX, and Cyprus Mines Corporation (Cyprus Mines), a wholly owned subsidiary of CAMC, are among those targets. Cyprus Mines was engaged in talc mining from 1964 until 1992 when it exited its talc business by conveying it to a third party in two related transactions. Those transactions involved (i) a transfer by Cyprus Mines of the assets of its talc business to a newly formed subsidiary that assumed all pre-sale and post-sale talc liabilities, subject to limited reservations, and (ii) a sale of the
19

stock of that subsidiary to the third party. In 2011, the third party sold that subsidiary to Imerys Talc America (Imerys), an affiliate of Imerys S.A.
Cyprus Mines has contractual indemnification rights, subject to limited reservations, against Imerys, which has historically acknowledged those indemnification obligations, and had taken responsibility for all cases tendered to it. However, on February 13, 2019, Imerys filed for Chapter 11 bankruptcy protection, which triggered an immediate automatic stay under the federal bankruptcy code prohibiting any party from continuing or initiating litigation or asserting new claims against Imerys. As a result, Imerys is no longer defending the talc lawsuits against Cyprus Mines and CAMC. In addition, Imerys has taken the position that it alone owns, and has the sole right to access, the proceeds of the legacy insurance coverage of Cyprus Mines and CAMC for talc liabilities. In late March 2019, Cyprus Mines and CAMC challenged this position and obtained emergency relief from the bankruptcy court to gain access to the insurance until the question of ownership and contractual access can be decided in an adversary proceeding before the bankruptcy court, which was previously scheduled for October 2019, but is being rescheduled for early 2020.
During first-quarter 2019, in a case pending at the time Imerys filed bankruptcy, a California jury entered a $29 million verdict against Johnson & Johnson and Cyprus Mines, of which approximately $2 million was attributed to Cyprus Mines. Taking advantage of the temporary access to the insurance authorized by the bankruptcy court, Cyprus Mines used the insurance to fully resolve the case. Cyprus Mines and the insurers also settled several other cases set for trial in recent months, and secured delays or dismissals in other cases. At September 30, 2019, Cyprus Mines had accrued approximately $5 million related to these cases. Multiple trials have been scheduled over the remainder of 2019 and the first half of 2020, and others may be scheduled prior to the adversary proceeding regarding the legacy insurance.
FCX believes that Cyprus Mines and CAMC each has strong defenses to legal liability and that both should have access to the legacy insurance to cover defense costs, settlements and judgments, at least until the bankruptcy court decides otherwise or the insurance is exhausted. At this time, FCX cannot estimate the range of possible loss associated with these proceedings, but it does not currently believe the amount of any such losses are material to its consolidated financial statements. However, there can be no assurance that future developments will not alter this conclusion.
Tax and Other Matters
As discussed in Note 12 of FCX’s 2018 Form 10-K, PT-FI received assessments from the local regional tax authorities in Papua, Indonesia, for additional taxes and penalties related to surface water taxes. In May 2019, PT-FI agreed to pay 1.394 trillion rupiah ($99 million based on the exchange rate at September 30, 2019), to settle historical disputes. In August 2019, PT-FI agreed to a revised payment schedule, paying 708.5 billion rupiah ($50 million) in October 2019, with the remaining 685.5 billion rupiah ($49 million based on the exchange rate at September 30, 2019) to be paid in February 2021. As a result of the May 2019 settlement, in second-quarter 2019, PT-FI recorded charges of $28 million to production and delivery costs ($69 million was previously accrued in 2018 for this matter). In accordance with PT-FI’s special mining license (IUPK), PT-FI is also obligated to pay surface water taxes of $15 million annually, beginning in 2019, which are recognized in production and delivery costs as incurred.
Refer to Note 12 for discussion of updates on PT-FI’s export duty matter and mine development cost tax matters.
On September 12, 2019, PT-FI received approval from the Indonesian government to increase its export quota from approximately 180,000 dry metric tons (DMT) of concentrate to approximately 680,000 DMT for the current export period, which expires March 8, 2020.
In March 2019, PT Smelting (PT-FI’s 25 percent-owned smelter and refinery in Indonesia) received an extension of its anode slimes export license through March 11, 2020.

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.

NOTE 11. NEW ACCOUNTING STANDARDS
Leases. Effective January 1, 2019, FCX adopted the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) that requires lessees to recognize most leases on the balance sheet. FCX elected the practical expedients allowing it to (i) apply the provisions of the updated lease guidance at the effective date, without adjusting the comparative periods presented and (ii) not reassess lease contracts, lease classification and initial direct costs of leases existing at adoption. FCX also elected an accounting policy to not recognize a lease asset and liability for leases with a term of 12 months or less and a purchase option that is not expected to be exercised.
FCX leases various types of properties, including offices and equipment under non-cancelable leases. Nearly all of FCX’s leases were considered operating leases under the new ASU. Adoption of this ASU resulted in the recognition of $243 million in lease right-of-use assets and lease liabilities as of January 1, 2019.
The components of FCX’s leases presented in the consolidated balance sheet as of September 30, 2019, follow (in millions):

Lease right-of-use assets (included in property, plant, equipment and mine development costs, net) | $ | 241 |
Short-term lease liabilities (included in accounts payable and accrued liabilities) | $ | 45 |
Long-term lease liabilities (included in other liabilities) | 211 |
Total lease liabilities | $ | 256 |

Operating lease costs, primarily included in production and delivery expense in the consolidated statement of operations, are as follows (in millions):

| Three Months Ended |  | Nine Months Ended
| September 30, 2019 |  | September 30, 2019
Operating leases | $ | 11 |  |  | $ | 44 |
Variable and short-term leases | 19 |  |  | 59 |
Total operating lease costs | $ | 30 |  |  | $ | 103 |

Lease costs totaled $80 million for the year 2018.
FCX paid $32 million during the first nine months of 2019 for lease liabilities recorded in the consolidated balance sheet (primarily included in operating cash flows in the consolidated statements of cash flows). As of September 30, 2019, the weighted-average discount rate used to determine the lease liabilities was 5.6 percent and the weighted-average remaining lease term was 8.5 years.
The future minimum payments for leases presented in the consolidated balance sheet at September 30, 2019, follow (in millions):

Remaining three months of 2019 | $ | 14 |
2020 | 55 |
2021 | 42 |
2022 | 35 |
2023 | 31 |
Thereafter | 155 |
Total payments | 332 |
Less amount representing interest | (76 | )
Present value of net minimum lease payments | 256 |
Less current portion | (45 | )
Long-term portion | $ | 211 |

Financial Instruments. In June 2016, FASB issued an ASU that requires entities to estimate all expected credit losses for most financial assets held at the reporting date based on an expected loss model, which requires consideration of historical experience, current conditions, and reasonable and supportable forecasts. This ASU also requires enhanced disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses. For public companies, this ASU is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. Currently, FCX does not expect this guidance to have a material impact on its consolidated financial statements.
NOTE 12. SUBSEQUENT EVENTS
FCX evaluated events after September 30, 2019, and through the date the consolidated financial statements were issued, and took into account events and transactions occurring during this period requiring recognition or disclosure in these consolidated financial statements.
Timok Transaction. In 2016, FCX sold an interest in the upper zone of the Timok exploration project in Serbia for cash consideration of $135 million and contingent consideration of up to $107 million payable to FCX in stages upon achievement of defined development milestones.
In November 2019, FCX entered into an agreement to sell its interest in the lower zone of the Timok exploration project to an affiliate of the purchaser in the 2016 transaction, for cash consideration of $240 million at closing plus deferred payments of up to $150 million. The deferred payments will be based on the future sale of products (as defined in the agreement) from the Timok lower zone. For a period of 12 months after the third anniversary of the initial sale of products from the Timok exploration project, the purchaser can settle, or FCX can demand payment of, such deferred payment obligation, in each case, for a total of $60 million. In addition, in lieu of such payment upon achievement of defined development milestones, the purchaser agreed to pay the $107 million contingent consideration provided for in the 2016 transaction in three installment payments of $45 million by July 31, 2020, $50 million by December 31, 2021, and $12 million by March 31, 2022.
Upon closing, FCX expects to record a gain of approximately $340 million, consisting of the cash consideration payment ($240 million) and the aggregate amount of the three installment payments (approximately $100 million after discounting).
The transaction is expected to close by first-quarter 2020, subject to receipt of customary regulatory approvals.
PT-FI Export Duty Matter. As discussed in Note 12 of FCX’s 2018 Form 10-K, in accordance with PT-FI’s 2017 Memorandum of Understanding with the Indonesian government, PT-FI agreed to pay export duties of 5 percent on the value of copper concentrate export sales until completion of the divestment and new IUPK. The Indonesia Customs Office applied a 7.5 percent duty. PT-FI paid the 2.5 percent difference for the period between April 2017 and December 21, 2018, totaling $155 million, under protest and appealed the disputed amounts to the Indonesia Tax Court. The Indonesia Tax Court subsequently announced rulings in favor of PT-FI related to individual cases involving $29 million of the disputed amounts, which were refunded by the Indonesia Customs Office to PT-FI.
The Indonesia Customs Office appealed the Indonesia Tax Court decisions on these cases to the Indonesia Supreme Court. On October 29, 2019, the Indonesia Supreme Court posted on its website rulings unfavorable to PT-FI for certain of the appealed cases involving approximately half of the $29 million that had been refunded to PT-FI.
As a result of the October 2019 ruling, under applicable accounting guidance, FCX recorded a charge of $155 million ($76 million to net loss attributable to common stock or $0.05 per share) during third-quarter 2019 to fully reserve for this matter. PT-FI continues to believe that a 5 percent export duty was applicable during this period and is evaluating options to recover these overpayments.
Under PT-FI’s IUPK entered into on December 21, 2018, the applicable export duty is 5 percent, declining to 2.5 percent when smelter development progress exceeds 30 percent and eliminated when smelter development progress exceeds 50 percent.

PT-FI Mine Development Cost Tax Matters. As discussed in Note 12 of FCX’s 2018 Form 10-K, PT-FI received unfavorable decisions from the Indonesia Tax Court with respect to its appeal of disallowed items on its 2012 and 2014 corporate income tax returns related to the tax treatment of mine development costs. On October 31, 2019, the Indonesia Supreme Court posted on its website a ruling unfavorable to PT-FI regarding its appeal of the Indonesia Tax Court decision regarding the tax treatment of mine development costs in its 2014 tax return. PT-FI is working with its advisors to estimate the aggregate potential exposure of this ruling, which could be significant after taking into account potential applicable penalties and interest and potential application to other years under dispute. PT-FI believes its treatment of mine development costs were appropriate under applicable provisions of the Contract of Work. The IUPK entered into on December 21, 2018, also provides for deductibility of mine development costs.
Under applicable accounting guidelines, adjustments for income tax matters such as this are reflected in the period in which the item becomes known and will be incorporated in FCX’s fourth-quarter 2019 results.
PT-FI will continue to defend its positions on these matters.

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, 2019, the related consolidated statements of operations, comprehensive (loss) income, and equity for the three- and nine-month periods ended September 30, 2019 and 2018, the consolidated statements of cash flows for the nine-month periods ended September 30, 2019 and 2018, 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, 2018, the related consolidated statements of operations, comprehensive income (loss), cash flows and equity for the year then ended, and the related notes (not presented herein); and in our report dated February 15, 2019, 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, 2018, 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, 2018 (2018 Form 10-K), 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.
EXPLANATORY NOTE
The consolidated financial results included in this quarterly report on Form 10-Q contain an adjustment to the consolidated financial results issued in our press release to report results for the third-quarter and nine-month periods ended September 30, 2019, furnished on Form 8-K on October 23, 2019 (third-quarter 2019 release). On October 29, 2019, the Indonesia Supreme Court posted on its website rulings unfavorable to PT-FI related to certain of the disputed export duty cases during the period April 2017 through December 2018. As a result of the unfavorable ruling, we, after issuance of our third-quarter 2019 release, recorded a charge of $155 million ($76 million to net loss attributable to common stock or $0.05 per share) in third-quarter 2019 to fully reserve for this matter. As a result, our net loss attributable to common stock increased from $131 million ($0.09 per share) to $207 million ($0.15 per share) in third-quarter 2019, and from $172 million ($0.12 per share) to $248 million ($0.17 per share) for the first nine months of 2019. The impact of the adjustment is reflected in the consolidated financial results included in this quarterly report on Form 10-Q. The adjustment had no impact on net operating cash flows or non-generally accepted accounting principles (GAAP) financial measures previously reported for third-quarter 2019. Refer to Note 12 for further discussion.
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 one of the world’s largest publicly traded copper producers. 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 North America and South America, including the large-scale Morenci minerals district in Arizona and the Cerro Verde operation in Peru.
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 leachable ores near the Safford operation in eastern Arizona, which is now approximately two-thirds complete, and PT Freeport Indonesia (PT-FI) continues to advance 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.
Our innovation-driven initiatives to enhance productivity and grow operations with low capital intensity are progressing. Early results from these initiatives have been positive, and we expect to incorporate these enhancements into our future mine plans for our North America and South America operations in 2020.
PT-FI commenced production from its significant underground ore bodies and continues to achieve important milestones to produce large-scale quantities of copper and gold following the transition from the Grasberg open pit (refer to “Operations - Indonesia Mining” for further discussion).
Net (loss) income attributable to common stock totaled $(207) million in third-quarter 2019, $556 million in third-quarter 2018, $(248) million for the first nine months of 2019 and $2.1 billion for the first nine months of 2018. The results for the 2019 periods, compared with 2018 periods, primarily reflect lower copper and gold sales volumes resulting from anticipated lower mill rates and ore grades in Indonesia as PT-FI transitions mining from the open pit to underground, lower copper prices and other net charges. Refer to “Consolidated Results” for further discussion.

Table of Contents
At September 30, 2019, we had $2.2 billion in consolidated cash and cash equivalents and $9.9 billion in total debt. We had no borrowings and $3.5 billion was available under our $3.5 billion, unsecured revolving credit facility at September 30, 2019. Refer to Note 5 for discussion of debt and “Capital Resources and Liquidity” for discussion of our third-quarter 2019 debt transactions.
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 prices 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.
Consolidated Sales Volumes
Following are our projected consolidated sales volumes for the year 2019 (which is a transition year for our Indonesia mining operations):

Copper (millions of recoverable pounds): |  |
North America copper mines | 1,450 |  |
South America mining | 1,170 |  |
Indonesia mining | 635 |  |
Total | 3,255 |  |
Gold (thousands of recoverable ounces) | 874 |  |
Molybdenum (millions of recoverable pounds) | 92 |  | a

a. | Projected molybdenum sales include 32 million pounds produced by our Molybdenum mines and 60 million pounds produced by our North America and South America copper mines.

Consolidated sales volumes in fourth-quarter 2019 are expected to approximate 870 million pounds of copper, 200 thousand ounces of gold and 24 million pounds of molybdenum. As PT-FI transitions mining from the open pit to underground, metal production is currently expected to improve significantly by 2021.
Consolidated Unit Net Cash Costs
Assuming average prices of $1,500 per ounce of gold and $12.00 per pound of molybdenum in fourth-quarter 2019 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 $1.76 per pound of copper for the year 2019.
The impact of price changes during fourth-quarter 2019 on consolidated unit net cash costs for the year 2019 would approximate $0.005 per pound for each $50 per ounce change in the average price of gold and $0.005 per pound for each $2 per pound change in the average price of molybdenum. Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices, primarily for gold and molybdenum. Refer to “Consolidated Results – Production and Delivery Costs” for further discussion of consolidated production costs for our mining operations.
Consolidated Operating Cash Flow
Our consolidated operating cash flows vary with sales volumes; prices realized from copper, gold and molybdenum sales; production costs; income taxes; other working capital changes; and other factors. Based on current sales volume and cost estimates, and assuming average prices of $2.60 per pound of copper, $1,500 per ounce of gold and $12.00 per pound of molybdenum in fourth-quarter 2019, our consolidated operating cash flows are estimated to approximate $1.6 billion (including $0.2 billion of working capital sources and timing of other tax payments) for the year 2019. Estimated consolidated operating cash flows for the year 2019 also reflect an estimated income tax provision of $0.3 billion (refer to “Consolidated Results – Income Taxes” for further discussion of our projected income tax rate for the year 2019). The impact of price changes during fourth-quarter 2019 on operating cash flows would approximate $90 million for each $0.10 per pound change in the average price of copper, $10 million for each $50 per ounce change in the average price of gold and $15 million for each $2 per pound change in the average price of molybdenum.

Consolidated Capital Expenditures
Consolidated capital expenditures are expected to approximate $2.6 billion for the year 2019, including $1.6 billion for major mining projects primarily associated with underground development activities in the Grasberg minerals district and development of the Lone Star copper leach project, and exclude estimates associated with the new smelter in Indonesia. A large portion of the capital expenditures relates to projects that are expected to add significant production and cash flow in future periods, enabling us to generate operating cash flows exceeding capital expenditures in future years. We have cash on hand and the financial flexibility to fund these expenditures and will continue to be disciplined in deploying capital.
MARKETS
World prices for copper, gold and molybdenum can fluctuate significantly. During the period from January 2009 through September 2019, the London Metal Exchange (LME) copper settlement price varied from a low of $1.38 per pound in 2009 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 $810 per ounce in 2009 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 $18.60 per pound in 2010. 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 2018 Form 10-K.
This graph presents LME copper settlement prices and the combined reported stocks of copper at the LME, Commodity Exchange Inc., a division of the New York Mercantile Exchange, and the Shanghai Futures Exchange from January 2009 through September 2019. During third-quarter 2019, LME copper settlement prices ranged from a low of $2.51 per pound to a high of $2.75 per pound, averaged $2.63 per pound and settled at $2.60 per pound on September 30, 2019. During the first nine months of 2019, copper prices continued to be negatively impacted primarily by the trade dispute between the U.S. and China and a slowing global economy. The LME copper settlement price was $2.64 per pound on October 31, 2019.
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 2009 through September 2019. During third-quarter 2019, LBMA PM gold prices ranged from a low of $1,389 per ounce to a high of $1,546 per ounce, averaged $1,472 per ounce, and closed at $1,485 per ounce on September 30, 2019. The LBMA PM gold price was $1,511 per ounce on October 31, 2019.

Table of Contents
Following is a summary of changes in our consolidated revenues between periods (in millions):

| Three Months Ended September 30, |  | Nine Months Ended September 30,
Consolidated revenues - 2018 period | $ | 4,908 |  |  | $ | 14,944 |
Lower sales volumes: |  |  |

Other, including intercompany eliminations | (26 | ) |  | (105 | )
Consolidated revenues - 2019 period | $ | 3,153 |  |  | $ | 10,491 |

Sales Volumes. Consolidated copper and gold sales volumes decreased in the 2019 periods, compared to the 2018 periods, primarily reflecting anticipated lower mill rates and ore grades as PT-FI transitions mining from the open pit to underground. 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. Average realized prices in third-quarter 2019, compared with third-quarter 2018, were 6 percent lower for copper, 25 percent higher for gold and 4 percent higher for molybdenum, and average realized prices for the first nine months of 2019, compared with first nine months of 2018, were 8 percent lower for copper, 10 percent higher for gold and 4 percent higher for molybdenum.
Average realized copper prices include net (unfavorable) favorable adjustments to current period provisionally priced copper sales (i.e., provisionally priced sales in the third quarters of 2019 and 2018 and for the first nine months of 2019 and 2018) totaling $(15) million in third-quarter 2019 and $(115) million for the first nine months of 2019, compared with $18 million in third-quarter 2018 and $(172) million for the first nine months of 2018. As discussed in Note 6, 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 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, 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.
Prior Period Provisionally Priced Copper Sales. Net (unfavorable) favorable adjustments to prior periods’ provisionally priced copper sales (i.e., provisionally priced sales at June 30, 2019 and 2018 and December 31, 2018 and 2017) recorded in consolidated revenues totaled $(42) million in third-quarter 2019 and $58 million for the first nine months of 2019, compared with $(111) million in third-quarter 2018 and $(70) million for the first nine months of 2018. Refer to Notes 6 and 9 for a summary of total adjustments to prior period and current period provisionally priced sales.
At September 30, 2019, we had provisionally priced copper sales totaling 249 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $2.59 per pound, subject to final pricing over the next several months. We estimate that each $0.05 change in the price realized from the September 30,
39

Table of Contents
2019, provisional price recorded would have an approximate $9 million effect on our 2019 net income attributable to common stock. The LME copper price settled at $2.64 per pound on October 31, 2019.
Treatment Charges. Revenues from our concentrate sales are recorded net of treatment charges, which will vary with the sales volumes and the price of copper.
Purchased Copper. We purchase copper cathode primarily for processing by our Rod & Refining operations. Purchased copper volumes totaled 79 million pounds in third-quarter 2019 and 310 million pounds for the first nine months of 2019, compared with 93 million pounds in third-quarter 2018 and 257 million pounds for the first nine months of 2018.
Lower Cobalt Revenues. Cobalt revenues totaled $116 million in third-quarter 2019 and $407 million for the first nine months of 2019, compared with $260 million in third-quarter 2018 and $813 million for the first nine months of 2018. Lower revenues in the 2019 periods, compared with the 2018 periods, primarily reflect lower cobalt prices.
Atlantic Copper Revenues. Atlantic Copper revenues totaled $437 million in third-quarter 2019 and $1.6 billion for the first nine months of 2019, compared with $579 million in third-quarter 2018 and $1.8 billion for the first nine months of 2018. Lower revenues in the 2019 periods, compared with the 2018 periods, primarily reflect lower copper sales volumes and lower copper prices.
Royalties and Export Duties. Royalties are primarily for sales from PT-FI and vary with the volume of metal sold and the prices of copper and gold. PT-FI will continue to pay export duties until development progress for the new smelter in Indonesia exceeds 50 percent. The third quarter and first nine months of 2019 include charges totaling $166 million, primarily associated with an unfavorable Indonesia Supreme Court ruling related to certain disputed PT-FI export duties (refer to Note 12). Refer to Note 9 for a summary of royalty expense and export duties.
Production and Delivery Costs
Consolidated production and delivery costs totaled $2.7 billion in third-quarter 2019, $3.1 billion in third-quarter 2018, $8.6 billion for the first nine months of 2019 and $8.8 billion for the first nine months of 2018. Lower consolidated production and delivery costs in the 2019 periods, compared with the 2018 periods, primarily reflect lower copper volumes.
Site Production and Delivery Costs Per Pound. 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 site production and delivery costs (before net noncash and other costs) for our copper mines averaged $2.05 per pound of copper in third-quarter 2019, $1.73 per pound of copper in third-quarter 2018, $2.16 per pound of copper for the first nine months of 2019 and $1.70 per pound of copper for the first nine months of 2018. Higher consolidated site production and delivery costs per pound in the 2019 periods, compared with the 2018 periods, primarily reflect lower volumes associated with PT-FI’s transition from mining the open pit to underground. 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 $322 million in third-quarter 2019, $458 million in third-quarter 2018, $1.0 billion for the first nine months of 2019 and $1.4 billion for the first nine months of 2018. For the year 2019, consolidated DD&A is expected to approximate $1.45 billion, compared with $1.75 billion for the year 2018. Lower DD&A in the 2019 periods, compared with the 2018 periods, primarily reflects lower sales volumes, and lower UOP rates because of increased reserves at our North America and South America mines as a result of a higher copper price assumption at December 31, 2018.
Mining Exploration and Research Expenses
Consolidated exploration and research expenses for our mining operations totaled $25 million in third-quarter 2019, $27 million in third-quarter 2018, $83 million for the first nine months of 2019 and $72 million for the first nine months of 2018. 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 ore grades than our other North America copper mines. Exploration spending totaled $62 million for the first nine months of 2019 and is expected to approximate $80 million for the year 2019.
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 $20 million in third-quarter 2019, $8 million in third-quarter 2018, $85 million for the first nine months of 2019 and $76 million for the first nine months of 2018. Higher environmental obligations and shutdown costs in the 2019 periods, compared to the 2018 periods, primarily reflect increased legal expenses associated with our legacy talc mining subsidiaries. Refer to Note 8 for further discussion of talc-related litigation.
Interest Expense, Net
Consolidated interest costs (before capitalization) totaled $163 million in third-quarter 2019, $167 million in third-quarter 2018 and $508 million for both the first nine months of 2019 and 2018, and include interest expense associated with disputed Cerro Verde royalties and related matters totaling $14 million in third-quarter 2019, $1 million in third-quarter 2018, $44 million for the first nine months of 2019 and $7 million for the nine months of 2018. Consolidated interest costs, excluding interest expense for disputed Cerro Verde royalties and related matters, decreased in the 2019 periods, compared to the 2018 periods, primarily reflecting the redemption of our 3.100% Senior Notes due 2020 and a prepayment on the Cerro Verde credit facility. Refer to Note 5 for further discussion of our 2019 debt transactions.
Capitalized interest varies with the level of expenditures for our development projects and average interest rates on our borrowings, and totaled $40 million in third-quarter 2019, $24 million in third-quarter 2018, $107 million for the first nine months of 2019 and $72 million for the first nine months of 2018. Refer to “Capital Resources and Liquidity - Investing Activities” for discussion of capital expenditures associated with our major development projects.
Income Taxes

a. | Represents income from continuing operations before income taxes and equity in affiliated companies’ net earnings.

b. | In addition to our North America mining operations, the U.S. jurisdiction reflects corporate-level expenses, which include interest expense associated with senior notes, general and administrative expenses, and environmental obligations and shutdown costs.

c. | The first nine months of 2019 include tax credits of $12 million associated with the settlement of state income tax examinations and $12 million associated with state law changes. The first nine months of 2018 include a tax credit of $5 million associated with the settlement of a state income tax examination.

d. | Includes a tax charge of $5 million ($4 million net of noncontrolling interest) primarily for non-deductible penalties related to PT-FI’s surface water tax settlement.

e. | Refer to Note 12 for further discussion of the unfavorable Indonesia Supreme Court ruling related to certain disputed PT-FI export duties.

f. | Includes net tax charges totaling $49 million ($15 million net of noncontrolling interests) primarily to adjust deferred taxes on historical balance sheet items in accordance with tax accounting principles.

41

Table of Contents

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

h. | Our consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which we operate, excluding the U.S. jurisdiction. Because our U.S. jurisdiction generated net losses in the first nine months of 2019 that will not result in a realized tax benefit, applicable accounting rules require us to adjust our estimated annual effective tax rate to exclude the impact of U.S. net losses.

Assuming achievement of current sales volume and cost estimates and average prices of $2.60 per pound for copper, $1,500 per ounce for gold and $12.00 per pound for molybdenum in fourth-quarter 2019, we estimate our consolidated tax provision for the year 2019 would approximate $0.3 billion. Changes in sales volumes and average prices during fourth-quarter 2019 would incur tax impacts at estimated effective rates of 38 percent for Indonesia, 40 percent for Peru and 0 percent for the U.S.
Changes to the relative proportions of jurisdictional income result in fluctuations to our consolidated effective income tax rate. Because of our U.S. tax position, we do not record a financial statement impact for income or losses generated in the U.S.; therefore, the consolidated effective tax rate is generally higher than the international rates at lower copper prices and lower than international rates at higher copper prices.
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 production is sold as 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 pursue projects to enhance productivity through innovative technologies and to identify opportunities to reduce the capital intensity of our potential long-term development projects. Early results from innovation initiatives have been positive, and we expect to incorporate these enhancements into our future mine plans in 2020.
Through exploration drilling, we have identified a significant resource at our wholly owned Lone Star copper leach project located near the Safford operation in eastern Arizona. An initial project to develop the Lone Star leachable ores commenced in 2018, with first production expected by the end of 2020. Initial production from the Lone Star leachable ores is expected to average approximately 200 million pounds of copper per year, with the potential for future expansion options. Total capital costs for the initial project, 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, 2019, approximately $575 million has been incurred for this project, which is on schedule and within budget. The project also advances exposure to a significant sulfide resource. We expect to incorporate positive drilling and ongoing results in our future development plans.

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

North America’s consolidated copper sales volumes of 395 million pounds in third-quarter 2019 were higher than third-quarter 2018 copper sales volumes of 350 million pounds, primarily reflecting higher leach production and higher mining and milling rates. North America’s consolidated copper sales volumes totaled 1.1 billion pounds for each of the first nine months of 2019 and 2018. North America copper sales are estimated to approximate 1.45 billion pounds for the year 2019.
Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations.

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 were $1.92 per pound of copper in third-quarter 2019 and $1.91 per pound for the first nine months of 2019, $1.82 per pound in third-quarter 2018 and $1.79 per pound for the first nine months of 2018. The increase in the 2019 periods, compared to the 2018 periods, primarily reflects higher mining and milling 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.
Average unit net cash costs (net of by-product credits) for our North America copper mines are expected to approximate $1.90 per pound of copper for the year 2019, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $12.00 per pound in fourth-quarter 2019. The impact of

price changes during fourth-quarter 2019 on North America's average unit net cash costs for the year 2019 would approximate $0.01 per pound for each $2 per pound change in the average price of molybdenum.
South America Mining
We operate two copper mines in South America – Cerro Verde in Peru (in which we own a 53.56 percent interest) and El Abra in Chile (in which we own a 51 percent interest), 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 September 2019, El Abra and its two workers' unions signed new CLAs, which expire on April 30, 2023.
Operating and Development Activities. Cerro Verde’s expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies and have continued to perform well. Debottlenecking projects and additional initiatives to enhance operating rates continue to be advanced.
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 continue to be advanced to determine the optimal scope and timing for the project.
Operating Data. Following is summary consolidated operating data for South America mining:

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

South America’s consolidated copper sales volumes totaled 261 million pounds in third-quarter 2019, 326 million pounds in third-quarter 2018, 838 million pounds for the first nine months of 2019 and 928 million pounds for the first nine months of 2018. Lower sales volumes for the 2019 periods, compared to the 2018 periods, reflect lower ore grades at Cerro Verde and the timing of shipments. Production and sales for the third quarter and first nine months of 2019 were impacted by protests associated with an unaffiliated copper development project in Peru that blocked access to the shipping ports and main transportation routes, mill maintenance activities and mine sequencing changes at Cerro Verde that delayed access to higher grade material. The first nine months of 2019

b. | Includes charges of $0.02 per pound of copper for the first nine months of 2019 associated with weather-related impacts at El Abra.

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) were $1.81 per pound of copper in both third-quarter 2019 and 2018, $1.74 per pound for the first nine months of 2019 and $1.76 per pound for the first nine months of 2018. Excluding charges in 2018 for Cerro Verde's new three-year CLA, average unit net cash costs (net of by-product credits) for the 2019 periods were higher, primarily reflecting lower copper sales volumes.
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 South America mining are expected to approximate $1.73 per pound of copper for the year 2019, based on current sales volume and cost estimates and assuming an average price of $12.00 per pound of molybdenum in fourth-quarter 2019.
Indonesia Mining
PT-FI’s assets include one of the world’s largest copper and gold deposits at the Grasberg minerals district in Papua, Indonesia. PT-FI produces copper concentrate that contains significant quantities of gold and silver. Effective December 21, 2018, our ownership interest in PT-FI is 48.76 percent. We manage PT-FI’s mining operations and consolidate PT-FI in our financial statements. As further discussed in Note 1, our economic interest in PT-FI is expected to approximate 81 percent through 2022.
Substantially all of PT-FI’s copper concentrate is sold under long-term contracts. During the first nine months of 2019, 67 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 and union officials have commenced discussions for a new two-year labor agreement. The existing agreement, which expired in September 2019, will continue in effect until a new agreement is consummated.

Table of Contents
Operating and Development Activities. PT-FI continues to mine the final stages of the Grasberg open pit and currently expects to complete mining in the open pit in fourth-quarter 2019, subject to geotechnical conditions.
PT-FI has commenced production from its significant underground ore bodies and continues to achieve important milestones 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 for the four-year period 2019 through 2022, net of scheduled contributions from PT Indonesia Asahan Aluminium (Persero) (PT Inalum). In accordance with applicable accounting guidance, aggregate costs (before scheduled contributions from PT Inalum), which are expected to average $0.95 billion per year for the four-year period 2019 through 2022, will be reflected as an investing activity in our cash flow statement, and contributions from PT Inalum will be reflected as a financing activity. Considering the long-term nature and size of these projects, actual costs could vary from these estimates.
The following provides additional information on the development of the Grasberg Block Cave underground mine, the Deep Mill Level Zone (DMLZ) underground mine and the new Indonesian smelter. Estimates of timing of future production from the underground mines continue to be reviewed and may be modified as additional information becomes available.
Grasberg Block Cave. PT-FI has commenced extraction of ore from the Grasberg Block Cave underground mine, which is the same ore body historically mined from the surface in the Grasberg open pit. Undercutting, drawbell construction and ore extraction activities in the Grasberg Block Cave underground mine continue to meet or exceed expectations. Ore extraction from the Grasberg Block Cave underground mine averaged 10,600 metric tons of ore per day in third-quarter 2019 and is expected to ramp up to 16,000 metric tons of ore per day by the end of 2019. Monitoring data on cave propagation in the Grasberg Block Cave underground mine is providing confidence in growing production rates over time. As existing drawpoints mature and additional drawpoints are added, cave expansion is expected to accelerate production rates from an average of 30,000 metric tons of ore per day in 2020 to 130,000 metric tons of ore per day in 2023 from five production blocks spanning 335,000 square meters.
DMLZ. The DMLZ underground mine, located east of the Grasberg ore body and below the Deep Ore Zone (DOZ) underground mine, has continued its ramp up of production. Hydraulic fracturing operations have been effective in managing rock stresses and pre-conditioning the cave following mining-induced seismic activity experienced in 2017 and 2018. Ore extraction continues to exceed expectations, averaging 9,800 metric tons of ore per day in third-quarter 2019. During third-quarter 2019, PT-FI elected to temporarily slow undercutting rates in one of the DMLZ production blocks until the desired cave shape was achieved. Undercutting re-commenced in September 2019. Ore extraction is expected to ramp up to 11,000 metric tons of ore per day by the end of 2019. Ongoing hydraulic fracturing operations combined with continued undercutting and drawbell openings in the two production blocks are expected to expand the cave, supporting higher production rates that are expected to average 28,000 metric tons of ore per day in 2020 and 80,000 metric tons of ore per day in 2022 from 3 production blocks.
Results to date from the Grasberg Block Cave and DMLZ underground mine are positive and in line with long-term plans to reach full productions rates. Because of the nature of block caving, estimates of timing of future production from PT-FI’s underground ore bodies will continue to be reviewed and may be modified as additional information becomes available.
Indonesian Smelter. In connection with the extension of PT-FI’s mining rights from 2031 to 2041, PT-FI committed to construct a new smelter in Indonesia by December 21, 2023. A site for the new smelter has been selected in Gresik near PT Smelting and ground preparation is in progress. Engineering and front-end engineering and design for the selected process technology are ongoing, with construction of the smelter expected to begin in 2020. The preliminary capital cost estimate for the project approximates $3 billion, and PT-FI is pursuing financing and commercial arrangements for this project. The economics of PT-FI’s share of the new smelter will be shared by PT-FI’s shareholders according to their respective share ownership percentages.

PT-FI’s consolidated sales of 139 million pounds of copper and 239 thousand ounces of gold in third-quarter 2019 and 464 million pounds of copper and 659 thousand ounces of gold for the first nine months of 2019 were lower than third-quarter 2018 consolidated sales of 368 million pounds of copper and 831 thousand ounces of gold and 1.0 billion pounds of copper and 2.1 million ounces of gold for the first nine months of 2018, primarily reflecting anticipated lower mill rates and ore grades as PT-FI transitions mining from the open pit to underground.
On September 12, 2019, PT-FI received approval from the Indonesian government to increase its export quota from approximately 180,000 dry metric tons (DMT) of concentrate to approximately 680,000 DMT for the current export period, which expires March 8, 2020.
Consolidated sales volumes from PT-FI are expected to approximate 635 million pounds of copper and 860 thousand ounces of gold in 2019. PT-FI will continue to monitor geotechnical conditions to determine the extent of mining in the Grasberg open pit. As PT-FI transitions mining from the open pit to underground, metal production is currently expected to improve significantly by 2021.
Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of

Because of the fixed nature of a large portion of PT-FI’s costs, unit net cash costs (credits) can vary significantly from quarter to quarter depending on copper and gold volumes. PT-FI’s unit net cash costs (including gold and silver credits) of $0.27 per pound of copper in third-quarter 2019 and $1.47 per pound for the first nine months of 2019, were higher than unit net cash credits of $0.72 per pound in third-quarter 2018 and $0.71 per pound for the first nine months of 2018, primarily reflecting lower copper and gold volumes.
Treatment charges vary with the volume of metals sold and the price of copper, and royalties vary with the volume of metals sold and the prices of copper and gold. PT-FI will continue to pay export duties until development progress for the new smelter in Indonesia exceeds 50 percent. The third quarter and first nine months of 2019 include charges totaling $166 million, primarily associated with an unfavorable Indonesia Supreme Court ruling related to certain disputed PT-FI export duties (refer to Note 12).
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.
Because certain assets are depreciated on a straight-line basis, PT-FI’s unit depreciation rate may vary with asset additions and the level of copper production and sales.
PT Smelting intercompany (loss) profit represents the change in the deferral of 25 percent of PT-FI’s profit on sales to PT Smelting. Refer to “Smelting and Refining” below for further discussion.
Assuming an average gold price of $1,500 per ounce in fourth-quarter 2019 and achievement of current sales volume and cost estimates, unit net cash costs (including gold and silver credits) for PT-FI are expected to approximate $1.53 per pound of copper for the year 2019. The impact of price changes during fourth-quarter 2019 on PT-FI's average unit net cash costs for the year 2019 would approximate $0.03 per pound for each $50 per ounce change in the average price of gold.
PT-FI’s projected sales volumes and unit net cash costs for the year 2019 are dependent on a number of factors, including operational performance, mine sequencing changes and timing of shipments.
Molybdenum Mines
We have two wholly owned molybdenum mines in Colorado – the Henderson underground mine and the Climax open-pit mine. 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 7 million pounds of molybdenum in third-quarter 2019, 8 million pounds in third-quarter 2018, 24 million pounds for the first nine months of 2019 and 26 million pounds for the first nine months of 2018. Production decreased in the 2019 periods, compared to the 2018 periods, primarily reflecting lower ore grades. 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.
Unit net cash costs for our Molybdenum mines averaged $11.64 per pound of molybdenum in third-quarter 2019, $9.02 per pound in third-quarter 2018, $10.13 per pound for the first nine months of 2019 and $8.64 per pound for the first nine months of 2018. The increase in average unit net cash costs in the 2019 periods, compared to the 2018 periods, primarily reflects lower sales volumes. Based on current sales volume and cost estimates, average

Table of Contents
unit net cash costs for the Molybdenum mines are expected to approximate $10.50 per pound of molybdenum for the year 2019. 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.
During the first half of 2019, we incurred charges totaling $38 million for a maintenance turnaround at the Miami smelter. The next major maintenance turnaround at the Miami smelter is scheduled for 2021.
Atlantic Copper smelts and refines copper concentrate and markets refined copper and precious metals in slimes. During the first nine months of 2019, Atlantic Copper’s concentrate purchases include 32 percent from our copper mining operations and 68 percent 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 treatment charge 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 2019, PT-FI supplied substantially all of PT Smelting’s concentrate requirements. In March 2019, PT Smelting received a one-year extension of its anode slimes export license through March 11, 2020.
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 to operating income totaling $4 million ($4 million to net loss attributable to common stock) in third-quarter 2019, $40 million ($24 million to net income attributable to common stock) in third-quarter 2018, $24 million ($20 million to net loss attributable to common stock) for the first nine months of 2019 and $13 million ($4 million to net income attributable to common stock) for the first nine months of 2018. 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 $39 million at September 30, 2019. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in our net deferred profits and quarterly earnings.
CAPITAL RESOURCES AND LIQUIDITY
Our consolidated operating cash flows vary with sales volumes; prices realized from copper, gold and molybdenum sales; production costs; income taxes; other working capital changes; and other factors. We believe that we have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. We continue to advance a project to develop the Lone Star leachable ores near our 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.
As presented in “Outlook,” our projected capital expenditures for the year 2019 are approximately $1.0 billion higher than projected operating cash flows. A large portion of the capital expenditures relate to projects that are expected to add significant production and cash flow in future periods, enabling us to generate operating cash flows exceeding capital expenditures in future years. We have cash on hand and the financial flexibility to fund these expenditures and will continue to be disciplined in deploying capital. Subject to future commodity prices for copper, gold and molybdenum, we expect estimated consolidated operating cash flows in 2019, 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.

a. Rounds to less than $0.1 billion.
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 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
At September 30, 2019, our consolidated debt totaled $9.9 billion, with a related weighted-average interest rate of 4.6 percent. At September 30, 2019, we had no borrowings, $13 million in letters of credit issued and $3.5 billion of availability under our revolving credit facility.
On August 15, 2019, we completed the sale of $1.2 billion of senior notes, consisting of $600 million aggregate principal amount of 5.00% Senior Notes due 2027 and $600 million aggregate principal amount of 5.25% Senior Notes due 2029. We used the net proceeds from the senior notes offering to fund the previously announced make-whole redemption of all of our outstanding 6.875% Senior Notes due 2023, and the concurrent tender offers to purchase a portion of our 4.00% Senior Notes due 2021 and 3.55% Senior Notes due 2022. As a result of the redemption and tender offers, we recorded a third-quarter 2019 loss on early extinguishment of debt totaling $21 million.
Refer to Note 5 for discussion of debt.
Operating Activities
We generated consolidated operating cash flows of $1.3 billion (including $0.1 billion of working capital sources and timing of other tax payments) for the first nine months of 2019 and $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. Lower operating cash flows for the first nine months of 2019, compared with the first nine months of 2018, primarily reflect lower copper and gold sales volumes and lower copper prices.
Investing Activities
Capital Expenditures. Capital expenditures, including capitalized interest, totaled $1.9 billion for the first nine months of 2019, including approximately $1.1 billion for major mining projects. Capital expenditures, including capitalized interest, totaled $1.4 billion for the first nine months of 2018, including approximately $0.9 billion for major mining projects. Higher capital expenditures for the first nine months of 2019, compared with the first nine months of 2018, primarily reflect underground development activities in the Grasberg minerals district and development of the Lone Star copper leach project. Refer to “Outlook” for further discussion of projected capital expenditures for the year 2019.
Proceeds from sales of oil and gas properties. We received $98 million of proceeds from sales of oil and gas properties for the first nine months of 2019, including $50 million in contingent consideration received associated with the 2016 sale of onshore California oil and gas properties.

Net repayments of debt for the first nine months of 2018 totaled $1.9 billion, primarily consisting of $1.4 billion of 2.375% Senior Notes that matured in March 2018 and $454 million for senior notes due in 2022 and 2023.
Cash Dividends and Distributions Paid. We paid cash dividends on our common stock totaling $218 million for the first nine months of 2019 and $145 million for the first nine months of 2018. On September 25, 2019, we declared a quarterly cash dividend of $0.05 per share on our common stock, which was paid on November 1, 2019, to shareholders of record as of October 15, 2019. The declaration of dividends is at the discretion of the Board of Directors (Board) and will depend upon our financial results, cash requirements, future prospects and other factors deemed relevant by the Board.
Cash dividends and distributions paid to noncontrolling interests totaled $79 million for the first nine months of 2019 and $241 million for the first nine months of 2018. These payments will vary based on the operating results and cash requirements of our consolidated subsidiaries.
Contributions from Noncontrolling Interests. During the first nine months of 2019, we received equity contributions totaling $133 million from PT Inalum for their share of capital spending on PT-FI underground mine development projects and costs for the new smelter in Indonesia.
CONTRACTUAL OBLIGATIONS
During the first nine months of 2019, we reduced our total debt by $1.2 billion. Additionally, during third-quarter 2019, we issued $1.2 billion in new senior notes and used the net proceeds to redeem and purchase other senior notes. Refer to Note 5 for further discussion of debt.
There have been no other material changes in our contractual obligations since December 31, 2018. Refer to Part II, Items 7. and 7A. in our 2018 Form 10-K, for information regarding our contractual obligations.

NEW ACCOUNTING STANDARDS
Refer to Note 11 for a summary of recently adopted accounting standards.
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 (loss) 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 (loss) 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.

Forward-looking statements are all statements other than statements of historical facts, such as plans, projections or expectations relating to ore grades and milling rates; production and sales volumes; unit net cash costs; operating cash flows; capital expenditures; our expectations regarding our share of PT-FI’s net (loss) income and future cash flows through 2022; PT-FI’s development, financing, construction and completion of a new smelter in Indonesia; PT-FI’s compliance with environmental standards under the framework established by Indonesia’s Ministry of Environment and Forestry; exploration efforts and results; development and production activities, rates and costs; liquidity; tax rates; export quotas and duties (including PT-FI’s evaluation of options to recover its overpayment of export duties); the impact of copper, gold and molybdenum price changes; the impact of deferred intercompany profits on earnings; reserve estimates; consummation of the pending Freeport Cobalt transaction and the pending Timok transaction; execution of the settlement agreement associated with the Louisiana coastal erosion cases; and future dividend payments, 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; changes in mine plans; production rates; timing of shipments; results of feasibility studies; potential inventory adjustments; potential impairment of long-lived mining assets; satisfaction of customary closing conditions, including receipt of regulatory approvals to consummate the pending Freeport Cobalt transaction and the pending Timok transaction; the potential effects of violence in Indonesia generally and in the province of Papua; the Indonesian government’s extension of PT-FI's export license after March 8, 2020; risks associated with underground mining; satisfaction of requirements in accordance with PT-FI’s IUPK to extend mining rights from 2031 through 2041; industry risks; regulatory changes; political and social risks (including ongoing social unrest and protests in Peru and Chile); labor relations; weather- and climate-related risks; environmental risks; litigation results (including final disposition of Indonesia export duty and mine development cost matters); cybersecurity incidents; and other factors described in more detail in Part I, Item 1A. “Risk Factors” of our 2018 Form 10-K.
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.
