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. Operating results for the three-month period ended March 31, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.
Attribution of PT Freeport Indonesia (PT-FI) Net Income. 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. For first-quarter 2019, PT-FI’s net income totaled $52 million, of which $43 million was attributed to FCX. PT-FI’s cumulative net loss since the December 21, 2018, transaction date through March 31, 2019, totaled $(84) million, of which $(68) 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.

NOTE 2. EARNINGS PER SHARE
FCX calculates its basic net income per share of common stock under the two-class method and calculates its diluted net income per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income per share of common stock was computed by dividing net income attributable to common stockholders by the weighted-average shares of common stock outstanding during the period. Diluted net income per share of common stock was calculated by including the basic weighted-average shares of common stock outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be anti-dilutive.
Reconciliations of net income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted net 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 income per share of common stock. Stock options for 39 million shares of common stock in first-quarter 2019 and 33 million shares of common stock in first-quarter 2018 were excluded.

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

FCX recorded charges for adjustments to cobalt metals inventory carrying values of $57 million in first-quarter 2019 because of lower cobalt prices.
NOTE 4. INCOME TAXES
Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. FCX’s consolidated effective income tax rate was 57 percent for first-quarter 2019 and 38 percent for first-quarter 2018. Geographic sources of FCX’s benefit from (provision for) income taxes follow (in millions):

| Three Months Ended |
| March 31, |
| 2019 |  | 2018 |
U.S. operations | $ | 2 |  |  | $ | 3 |  |
International operations | (107 | ) |  | (509 | ) |
Total | $ | (105 | ) |  | $ | (506 | ) |

FCX's first-quarter 2019 consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which FCX operates, excluding the U.S. jurisdiction. Because FCX's U.S. jurisdiction generated net losses in first-quarter 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.

Long-term debt |  | $ | 9,902 |  |  | $ | 11,124 |

Revolving Credit Facility. At March 31, 2019, there were no borrowings outstanding and $13 million in letters of credit issued under FCX’s revolving credit facility, resulting in availability of approximately $3.5 billion, of which approximately $1.5 billion could be used for additional letters of credit.
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 (the scheduled maturity date). 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.
Cerro Verde Credit Facility. In March 2019, Cerro Verde prepaid $200 million of its credit facility, which resulted in a $1 million loss recorded to early extinguishment of debt.
Interest Expense, Net. Consolidated interest costs totaled $178 million in first-quarter 2019 and $176 million in first-quarter 2018. Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $32 million in first-quarter 2019 and $25 million in first-quarter 2018.
Common Stock. On March 27, 2019, FCX declared a quarterly cash dividend of $0.05 per share on its common stock, which was paid on May 1, 2019, to common stockholders of record as of April 15, 2019.

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 March 31, 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 three-month periods ended March 31, 2019 and 2018. At March 31, 2019, FCX held copper futures and swap contracts that qualified for hedge accounting for 66 million pounds at an average contract price of $2.81 per pound, with maturities through November 2020.
A summary of gains (losses) recognized in revenues for derivative financial instruments related to commodity contracts that are designated and qualify as fair value hedge transactions, including the unrealized (losses) gains 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 March 31, 2019, Atlantic Copper held net copper forward purchase contracts for 11 million pounds at an average contract price of $2.92 per pound, with maturities through June 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 March 31, 2019, the maximum amount of credit exposure associated with derivative transactions was $93 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 $1.5 billion at March 31, 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 March 31, 2019, FCX has contingent consideration assets related to the 2016 asset sales of TF Holdings Limited (TFHL), onshore California oil and gas properties and the 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 first-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.

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. Also in 2016, FCX Oil & Gas LLC’s (FM O&G) sale of its onshore California oil and gas properties included contingent consideration of up to $150 million, consisting of $50 million per year for 2018, 2019 and 2020 if the price of Brent crude oil averages over $70 per barrel in each of these calendar years. Future changes in the fair value of the contingent consideration derivative for the sale of (i) TFHL will continue to be recorded in discontinued operations and (ii) the onshore California oil and gas properties will continue to be recorded in operating income. The fair value of the contingent consideration derivative was (i) $58 million at March 31, 2019 (included in other current assets in the consolidated balance sheet), and $57 million at December 31, 2018 (included in other assets), associated with the sale of TFHL and (ii) $29 million at March 31, 2019 ($13 million included in other current assets and $16 million in other assets), and $16 million at December 31, 2018 (included in other assets), associated with the sale of the onshore California oil and gas properties. 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, FM O&G’s sale of its Deepwater GOM oil and gas properties included up to $150 million in contingent consideration that was recorded at the total amount under the loss recovery approach. The contingent consideration will be received over time as future cash flows are realized in connection with a third-party production handling agreement for an offshore platform. The first collection occurred in third-quarter 2018. The contingent consideration included in (i) other current assets totaled $19 million at March 31, 2019, and $27 million at December 31, 2018, and (ii) other assets totaled $119 million at March 31, 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.

Long-term debt, including current portion, is valued using available market quotes and, as such, is classified within Level 2 of the fair value hierarchy.
The techniques described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with other market participants, the use of different techniques or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the techniques used at March 31, 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 three 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 | (5 | ) |
Settlements | (5 | ) |
Fair value at March 31, 2019 | $ | 117 |  |

NOTE 8. CONTINGENCIES AND COMMITMENTS
Litigation
There were no significant updates to previously reported legal proceedings included in Note 12 of FCX’s 2018 Form 10-K, other than the matter below.
As discussed in Note 12 of FCX’s 2018 Form 10-K, 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 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 is currently scheduled for August 2019.
On March 13, 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 over the succeeding 90 days. Several trials have been scheduled in July and August 2019, and others may be scheduled prior to the adversary proceeding regarding the legacy insurance.

Table of Contents
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.
Other Matters
In March 2019, PT-FI’s export license was extended to March 8, 2020, and 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 March 31, 2019, follow (in millions):

Lease right-of-use assets (included in property, plant, equipment and mine development costs, net) | $ | 245 |
Short-term lease liabilities (included in accounts payable and accrued liabilities) | $ | 33 |
Long-term lease liabilities (included in other liabilities) | 223 |
Total lease liabilities | $ | 256 |

Operating lease costs in first-quarter 2019, primarily included in production and delivery expense in the consolidated statement of income, are as follows (in millions):

Operating leases | $ | 12 |
Variable and short-term leases | 21 |
Total lease costs | $ | 33 |

Lease costs totaled $80 million for the year 2018 and sublease income was immaterial.
During first-quarter 2019, FCX paid $10 million for lease liabilities recorded in the consolidated balance sheet (included in operating cash flows in the consolidated statements of cash flows). As of March 31, 2019, the weighted-average discount rate used to determine the lease liabilities was 5.7 percent and the weighted-average remaining lease term was 9.3 years.
The future minimum payments for leases presented in the consolidated balance sheets at March 31, 2019, follows (in millions):

Remaining nine months of 2019 | $ | 36 |
2020 | 45 |
2021 | 39 |
2022 | 33 |
2023 | 30 |
Thereafter | 155 |
Total payments | 338 |
Less amount representing interest | (82 | )
Present value of net minimum lease payments | 256 |
Less current portion | (33 | )
Long-term portion | $ | 223 |

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. FCX does not expect this guidance to have a material impact on its consolidated financial statements.
NOTE 12. SUBSEQUENT EVENTS
FCX evaluated events after March 31, 2019, and through the date the consolidated financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these consolidated financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
Freeport-McMoRan Inc.
Results of Review of Interim Financial Statements
We have reviewed the accompanying consolidated balance sheet of Freeport-McMoRan Inc. (the Company) as of March 31, 2019, the related consolidated statements of income, comprehensive income, cash flows and equity for the three-month periods ended March 31, 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, 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.
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, and PT Freeport Indonesia (PT-FI) has several projects in the Grasberg minerals district related to the development of its large-scale, long-lived, high-grade underground ore bodies (refer to “Operations - Indonesia Mining” for further discussion of PT-FI’s transition from open pit to underground mining). We are also pursuing other opportunities to enhance our mines’ net present values, and we continue to advance studies for future development of our copper resources, the timing of which will be dependent on market conditions.
Net income attributable to common stock totaled $31 million in first-quarter 2019 and $692 million in first-quarter 2018. First-quarter 2019 results, compared with the 2018 period, 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. Refer to “Consolidated Results” for further discussion.
At March 31, 2019, we had $2.8 billion in consolidated cash and cash equivalents and $9.9 billion in total debt. During first-quarter 2019, we redeemed all of our outstanding $1.0 billion aggregate principal amount of 3.100% Senior Notes due 2020 and repaid $200 million under Cerro Verde’s credit facility. We had no borrowings, and $3.5 billion is available under our $3.5 billion, unsecured revolving credit facility. Refer to Note 5 for further discussion of debt.
OUTLOOK
We continue to view the long-term outlook for our business positively, supported by limitations on supplies of copper and by the requirements for copper in the world’s economy. Our financial results vary as a result of fluctuations in market prices primarily for copper, gold and molybdenum, as well as other factors. World market prices for these commodities have fluctuated historically and are affected by numerous factors beyond our control. Refer to “Markets” for further discussion. Because we cannot control the price of our products, the key measures that management focuses on in operating our business are sales volumes, unit net cash costs, operating cash flow and capital expenditures.

Sales Volumes
Following are our projected consolidated sales volumes for the year 2019 (which reflect a transition year for Indonesia mining):

Copper (millions of recoverable pounds): |  |
North America copper mines | 1,375 |  |
South America mining | 1,250 |  |
Indonesia mining | 625 |  |
Total | 3,250 |  |
Gold (thousands of recoverable ounces) | 832 |  |
Molybdenum (millions of recoverable pounds) | 94 |  | a

a. | Projected molybdenum sales include 36 million pounds produced by our Molybdenum mines and 58 million pounds produced by our North America and South America copper mines.

Consolidated sales volumes for second-quarter 2019 are expected to approximate 800 million pounds of copper, 265 thousand ounces of gold and 25 million pounds of molybdenum. As PT-FI transitions mining from the open pit to underground, its production is expected to be significantly lower in 2019 and 2020, compared with 2018. Metal production is expected to improve significantly by 2021 following a ramp-up period.
Consolidated Unit Net Cash Costs
Assuming average prices of $1,300 per ounce of gold and $13.00 per pound of molybdenum for the remainder of 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 $1.75 per pound of copper for the year 2019. We expect unit net cash costs to decline by 2021 following a ramp-up period at PT-FI. The impact of price changes for the remainder of 2019 on consolidated unit net cash costs would approximate $0.01 per pound for each $50 per ounce change in the average price of gold and $0.02 per pound for each $2 per pound change in the average price of molybdenum. Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices, primarily for gold and molybdenum. Refer to “Consolidated Results – Production and Delivery Costs” for further discussion of consolidated production costs for our mining operations.
Consolidated Operating Cash Flow
Our consolidated operating cash flows vary with sales volumes; prices realized from copper, gold and molybdenum sales; production costs; income taxes; other working capital changes; and other factors. Based on current sales volume and cost estimates, and assuming average prices of $3.00 per pound of copper, $1,300 per ounce of gold and $13.00 per pound of molybdenum for the remainder of 2019, our consolidated operating cash flows are estimated to approximate $2.3 billion for the year 2019. Estimated consolidated operating cash flows for the year 2019 also reflect an estimated income tax provision of $0.6 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 the remainder of 2019 on operating cash flows would approximate $265 million for each $0.10 per pound change in the average price of copper, $30 million for each $50 per ounce change in the average price of gold and $95 million for each $2 per pound change in the average price of molybdenum.
Consolidated Capital Expenditures
Consolidated capital expenditures are expected to approximate $2.5 billion for the year 2019, including $1.5 billion for major mining projects primarily associated with underground development activities in the Grasberg minerals district and development of the Lone Star 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 March 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 March 2019. During first-quarter 2019, LME copper settlement prices ranged from a low of $2.64 per pound to a high of $2.98 per pound, averaged $2.82 per pound and settled at $2.94 per pound on March 29, 2019. The LME copper settlement price was $2.92 per pound on April 30, 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.

Revenues
Consolidated revenues totaled $3.8 billion in first-quarter 2019, compared with $4.9 billion in first-quarter 2018. Revenues from our mining operations primarily include the sale of copper concentrate, copper cathode, copper rod, gold in concentrate and molybdenum. Refer to Note 9 for a summary of product revenues. Following is a summary of changes in our consolidated revenues between periods (in millions):

|  | Three Months Ended March 31

Lower royalties and export duties |  | 68 |
Other, including intercompany eliminations |  | (83 | )
Consolidated revenues - 2019 period |  | $ | 3,792 |

Sales Volumes. Consolidated copper and gold sales volumes decreased in first-quarter 2019, compared with first-quarter 2018, primarily reflecting anticipated lower mill rates and ore grades in Indonesia 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. First-quarter 2019 average realized prices, compared with first-quarter 2018, were 7 percent lower for copper, 2 percent lower for gold and 6 percent higher for molybdenum.
Average realized copper prices include net favorable (unfavorable) adjustments to current period provisionally priced copper sales totaling $52 million in first-quarter 2019 and $(57) million in first-quarter 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 favorable (unfavorable) adjustments to prior periods’ provisionally priced copper sales (i.e., provisionally priced sales at December 31, 2018 and 2017) recorded in consolidated revenues totaled $70 million in first-quarter 2019 and $(78) million in first-quarter 2018. Refer to Notes 6 and 9 for a summary of total adjustments to prior period and current period provisionally priced sales.
At March 31, 2019, we had provisionally priced copper sales totaling 364 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $2.94 per pound, subject to final pricing over the next several months. We estimate that each $0.05 change in the price realized from the March 31, 2019, provisional price recorded would have an approximate $12 million effect on our 2019 net income attributable to common stock. The LME copper price settled at $2.92 per pound on April 30, 2019.
Purchased Copper. We purchase copper cathode primarily for processing by our Rod & Refining operations. Purchased copper volumes totaled 117 million pounds in first-quarter 2019 and 74 million pounds in first-quarter 2018.
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 also pays export duties until development progress for the new smelter in Indonesia exceeds 50 percent. Refer to Note 9 for a summary of royalty expense and export duties.
Production and Delivery Costs
Consolidated production and delivery costs totaled $2.9 billion in first-quarter 2019 and $2.8 billion in first-quarter 2018. Higher consolidated production and delivery costs in first-quarter 2019 primarily reflect costs at PT-FI that were historically shared under the joint venture formerly with Rio Tinto plc.
Mining Unit Site Production and Delivery Costs. Site production and delivery costs for our copper mining operations primarily include labor, energy and commodity-based inputs, such as sulphuric acid, reagents, liners, tires and explosives. Consolidated unit site production and delivery costs (before net noncash and other costs) for our copper mines averaged $2.17 per pound of copper in first-quarter 2019, compared with $1.67 per pound of copper in first-quarter 2018. Higher consolidated unit site production and delivery costs in first-quarter 2019, compared with first-quarter 2018, 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 $347 million in first-quarter 2019, compared with $451 million in first-quarter 2018. Lower DD&A in first-quarter 2019, compared with first-quarter 2018, primarily reflected lower sales volumes at PT-FI and lower UOP rates because of increased reserves at our North America and South America mines.
Mining Exploration and Research Expenses
Consolidated exploration and research expenses for our mining operations totaled $27 million in first-quarter 2019 and $21 million in first-quarter 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 is expected to approximate $70 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 $42 million in first-quarter 2019 and $9 million in first-quarter 2018.
Interest Expense, Net
Consolidated interest costs (before capitalization) totaled $178 million in first-quarter 2019 and $176 million in first-quarter 2018. Capitalized interest varies with the level of expenditures for our development projects and average interest rates on our borrowings, and totaled $32 million in first-quarter 2019 and $25 million in first-quarter 2018.
Income Taxes
Following is a summary of the approximate amounts used in the calculation of our consolidated income tax provision (in millions, except percentages):

| Three Months Ended March 31, |
| 2019 |  | 2018 |
| Income (Loss)a |  | Effective Tax Rate |  | Income Tax (Provision) Benefit |  | Income a |  | Effective Tax Rate |  | Income Tax (Provision) Benefit |

Consolidated FCX | $ | 183 |  |  | 57% | e | $ | (105 | ) |  | $ | 1,336 |  |  | 38% |  | $ | (506 | ) |

a. | Represents income (loss) from continuing operations before income taxes and equity in affiliated companies’ net losses.

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. | Includes a tax credit of $8 million ($6 million net of noncontrolling interest) associated with the reduction in PT-FI's statutory tax rates in accordance with its special mining license (IUPK).

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

e. | Our first-quarter 2019 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 first-quarter 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 $3.00 per pound for copper, $1,300 per ounce for gold and $13.00 per pound for molybdenum for the remainder of 2019, we estimate our consolidated effective tax rate for the year 2019 would approximate 41 percent (comprised of an estimated effective rate of 41 percent on South America income, 38 percent on Indonesia income and 0 percent for the U.S.). Variations in 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 sales is in the form of copper cathode or copper concentrate, a portion of which is shipped to Atlantic Copper (our wholly owned smelter). Molybdenum concentrate, gold and silver are also produced by certain of our North America copper mines.
Operating and Development Activities. We have significant undeveloped reserves and resources in North America and a portfolio of potential long-term development projects. Future investments will be undertaken based on the results of economic and technical feasibility studies, and are dependent on market conditions. We continue to pursue projects to enhance productivity through innovative technologies and to study opportunities to reduce the capital intensity of our potential long-term development projects.
Through exploration drilling, we have identified a significant resource at our wholly owned Lone Star project located near the Safford operation in eastern Arizona. An initial project to develop the Lone Star leachable ores commenced in first-quarter 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 March 31, 2019, approximately $385 million has been incurred for this project. The project also advances exposure to a significant sulfide resource. We expect to incorporate recent positive drilling and ongoing results in our future development plans.

Table of Contents
North America’s consolidated copper sales volumes of 320 million pounds in first-quarter 2019 were lower than first-quarter 2018 sales of 384 million pounds, primarily reflecting timing of shipments. North America copper sales are estimated to approximate 1.4 billion pounds for the year 2019, similar to 2018.
Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.
Gross Profit per Pound of Copper and Molybdenum
The following table summarizes unit net cash costs and gross profit per pound at our North America copper mines.

Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.91 per pound of copper in first-quarter 2019 were higher than unit net cash costs of $1.74 per pound in first-quarter 2018, primarily reflecting lower copper sales volumes.
Because certain assets are depreciated on a straight-line basis, North America’s average unit depreciation rate may vary with asset additions and the level of copper production and sales.
Average unit net cash costs (net of by-product credits) for our North America copper mines are expected to approximate $1.91 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 $13.00 per pound for the remainder of 2019. North
America’s average unit net cash costs for the year 2019 would change by approximately $0.03 per pound for each $2 per pound change in the average price of molybdenum for the remainder of 2019.

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.
Operating and Development Activities. Cerro Verde’s expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. Cerro Verde's concentrator facilities have continued to perform well, with average mill throughput rates of 386,500 metric tons of ore per day in first-quarter 2019. Debottlenecking projects and additional initiatives to enhance operating rates are being 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 are being advanced to determine the optimal scope and timing for the project.

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

South America’s consolidated copper sales volumes of 290 million pounds in first-quarter 2019 approximated first-quarter 2018, with lower volumes from El Abra being offset by higher volumes at Cerro Verde.
During first-quarter 2019, heavy rainfall and electrical storms resulted in a suspension of El Abra’s crushed leach stacking operations for approximately 35 days; operations resumed in mid-March. The estimated impact of the disruption on FCX's 2019 consolidated copper production approximates 30 million pounds, approximately half of which was in first-quarter 2019.
Copper sales from South America mines are expected to approximate 1.3 billion pounds for the year 2019, similar to 2018.

Our South America mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. Average unit net cash costs (net of by-product credits) of $1.59 per pound of copper in first-quarter 2019 were lower than unit net cash costs of $1.74 per pound in first-quarter 2018, primarily reflecting higher by-product credits.
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 $1.66 per pound of copper for the year 2019, based on current sales volume and cost estimates and assuming an average price of $13.00 per pound of molybdenum for the remainder of 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. Substantially all of PT-FI’s copper concentrate is sold under long-term contracts, and during first-quarter 2019, approximately half of PT-FI’s concentrate production was sold to PT Smelting (PT-FI’s 25-percent-owned smelter and refinery in Gresik, Indonesia).
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.
Operating and Development Activities. PT-FI is currently mining the final phase of the Grasberg open pit and expects to transition to the Grasberg Block Cave (GBC) underground mine in mid-2019. PT-FI continues to assess opportunities to recover additional ore from the open pit during the remainder of 2019, subject to mine planning considerations.
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. In aggregate, these underground ore bodies are expected to produce large-scale quantities of copper and gold following the transition from the Grasberg open pit.
PT-FI's estimated annual capital spending on underground mine development projects is expected to average $0.7 billion per year over the next four years, 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 $0.9 billion per year 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.
In connection with completion of the December 2018 transaction, PT-FI committed to construct a new smelter in Indonesia by December 21, 2023. PT-FI has reviewed various process technologies and has initiated front-end engineering and design for the selected technology. The preliminary capital cost estimate for the project is in the $3 billion range, and PT-FI intends to pursue financing, commercial and potential partner arrangements for this project. The economics of PT-FI’s share of the new smelter will be borne by PT-FI’s shareholders according to their respective share ownership percentages.
The following provides additional information on the continued development of the Common Infrastructure project, the GBC underground mine and the Deep Mill Level Zone (DMLZ) ore body that lies below the Deep Ore Zone (DOZ) underground mine.
Common Infrastructure and GBC Underground Mine. The Common Infrastructure project provides access to PT-FI’s large undeveloped underground ore bodies located in the Grasberg minerals district through a tunnel system located approximately 400 meters deeper than the existing underground tunnel system. In addition to providing access to the underground ore bodies, the tunnel system will enable PT-FI to conduct future exploration in prospective areas associated with currently identified ore bodies. The tunnel system was completed to the Big Gossan terminal, and development of the GBC and DMLZ underground mines is advancing using the Common Infrastructure project tunnels as access.
The GBC underground mine accounts for approximately half of PT-FI’s recoverable proven and probable reserves. Substantial progress has been made to prepare for the transition to mining of the GBC underground mine. First undercut blasting occurred in late 2018, and several drawbells have been constructed and blasted to prepare for mining. Cave production is in progress and on schedule. All underground mining levels and the ore flow system are being commissioned. Production rates over the next five years are expected to ramp up to 130,000 metric tons of ore per day.
Mine development capital for the GBC underground mine and associated Common Infrastructure is expected to approximate $6.8 billion, including $4.1 billion incurred through March 31, 2019 ($0.2 billion during first-quarter 2019).

Table of Contents
DMLZ. The DMLZ ore body lies below the DOZ mine at the 2,590-meter elevation and represents the downward continuation of mineralization in the Ertsberg East Skarn system and neighboring Ertsberg porphyry. In September 2015, PT-FI initiated pre-commercial production that represented ore extracted during the development phase for the purpose of obtaining access to the ore body. During third-quarter 2018, PT-FI commenced hydraulic fracturing activities to manage rock stresses and pre-condition the DMLZ underground mine for large-scale production following mining induced seismic activity experienced in 2017 and 2018. Results to date have been effective in managing rock stresses and pre-conditioning the cave. PT-FI expects to commence the ramp up of production in the DMLZ underground mine by mid-2019 and to reach full production rates of 80,000 metric tons per day in 2022. Estimates of timing of future production continue to be reviewed and may be modified as additional information becomes available.
Mine development capital costs for the DMLZ underground mine are expected to approximate $3.3 billion, including $2.6 billion incurred through March 31, 2019 ($0.1 billion during first-quarter 2019).

In March 2019, PT-FI's export license was extended to March 8, 2020. PT-FI's approved export quota for the current export period totals approximately 180,000 dry metric tons of concentrate. PT-FI plans to seek approval from the Indonesian government for an increase in its export quota for the current export period for expected higher production volumes associated with changes made to PT-FI’s production plan that was submitted to the Indonesian government in November 2018.
Indonesia mining’s consolidated sales of 174 million pounds of copper and 235 thousand ounces of gold in first-quarter 2019 were lower than first-quarter 2018 sales of 319 million pounds of copper and 603 thousand ounces of gold, primarily reflecting anticipated lower mill rates and ore grades as PT-FI transitions mining from the open pit to underground.

Table of Contents
As PT-FI transitions mining from the open pit to underground, production is expected to be significantly lower in 2019 and 2020, compared with 2018. Metal production is expected to improve significantly by 2021 following a ramp-up period. Consolidated sales volumes from Indonesia mining are expected to approximate 0.6 billion pounds of copper and 0.8 million ounces of gold in 2019.

A significant portion of PT-FI’s costs are fixed, and unit costs vary depending on production volumes and other factors. Indonesia mining had unit net cash costs (including gold and silver credits) of $1.84 per pound of copper in first-quarter 2019, compared with unit net cash credits of $0.63 per pound in first-quarter 2018, primarily reflecting lower gold and silver credits and lower copper sales volumes.
Treatment charges vary with the volume of metals sold and the price of copper, and royalties vary with the volume of metals sold and the prices of copper and gold.
Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods.
Because certain assets are depreciated on a straight-line basis, Indonesia mining’s unit depreciation rate may vary with asset additions and the level of copper production and sales.
PT Smelting intercompany profit (loss) represents the change in the deferral of 25 percent of PT-FI’s profit on sales to PT Smelting. Refer to “Smelting & Refining” below for further discussion.

Because of the fixed nature of a large portion of Indonesia’s costs, unit net cash costs vary from quarter to quarter depending on copper and gold volumes. Assuming an average gold price of $1,300 per ounce for the remainder of 2019 and achievement of current sales volume and cost estimates, unit net cash costs (including gold and silver credits) for Indonesia mining are expected to approximate $1.54 per pound of copper for the year 2019. Indonesia mining’s unit net cash costs for the year 2019 would change by approximately $0.05 per pound for each $50 per ounce change in the average price of gold for the remainder of 2019.
Indonesia mining's projected sales volumes and unit net cash costs for the year 2019 are dependent on a number of factors, including operational performance, timing of shipments, export quotas and workforce productivity.

Molybdenum Mines
We have two wholly owned molybdenum mines – the Henderson underground mine and the Climax open-pit mine - both in Colorado. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of the molybdenum concentrate produced at the Henderson and Climax mines, as well as from our North America and South America copper mines, is processed at our own conversion facilities.
Operating and Development Activities. Production from the Molybdenum mines totaled 8 million pounds of molybdenum in first-quarter 2019 and 9 million pounds in first-quarter 2018. 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 $9.80 per pound of molybdenum in first-quarter 2019 and $8.57 per pound in first-quarter 2018. Based on current sales volume and cost estimates, average unit net cash costs for the Molybdenum mines are expected to approximate $9.60 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.
Atlantic Copper smelts and refines copper concentrate and markets refined copper and precious metals in slimes. During first-quarter 2019, Atlantic Copper’s concentrate purchases include 35 percent from our copper mining operations and 65 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 first-quarter 2019, PT-FI supplied all of PT

Table of Contents
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 net income attributable to common stock of $14 million for first-quarter 2019 and $7 million for first-quarter 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 $34 million at March 31, 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 prices realized from copper, gold and molybdenum; our sales volumes; production costs; income taxes; other working capital changes; and other factors. We believe that we have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. We 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 2019 are approximately $0.2 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.
Cash
Following is a summary of the U.S. and international components of consolidated cash and cash equivalents available to the parent company, net of noncontrolling interests’ share, taxes and other costs at March 31, 2019 (in billions):

Cash at domestic companies | $ | 1.9 |  |

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 March 31, 2019, we had no borrowings, $13 million in letters of credit issued and $3.5 billion of availability under our revolving credit facility. Refer to Note 5 for further discussion of debt, including an amendment to extend our credit facility, and “Financing Activities” below.

We generated consolidated operating cash flows of $534 million (net of $27 million in working capital uses and timing of other tax payments) in first-quarter 2019 and $1.4 billion (net of $21 million in working capital uses and timing of other tax payments) in first-quarter 2018. Lower operating cash flows in first-quarter 2019, compared with first-quarter 2018, primarily reflect lower copper and gold sales volumes.
Investing Activities
Capital Expenditures. Capital expenditures, including capitalized interest, totaled $622 million in first-quarter 2019, including approximately $370 million for major mining projects. Capital expenditures, including capitalized interest, totaled $402 million in first-quarter 2018, including approximately $250 million for major mining projects. Higher capital expenditures in first-quarter 2019, compared with first-quarter 2018, primarily reflects underground development activities in the Grasberg minerals district and development of the Lone Star 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 $84 million of proceeds from sales of oil and gas properties in first-quarter 2019, including $50 million in contingent consideration received associated with the 2016 sale of onshore California oil and gas properties.
Intangible water rights and other, net. During first-quarter 2018, our North America copper mines purchased intangible water rights totaling $88 million.
Financing Activities
Debt Transactions. Net repayments of debt in first-quarter 2019 totaled $1.2 billion, consisting of the redemption of $1.0 billion aggregate principal amount of our 3.100% Senior Notes due 2020 and the repayment of $200 million under Cerro Verde's credit facility. We recorded losses on early extinguishment of debt totaling $6 million in first-quarter 2019.
Net repayments of debt in first-quarter 2018 totaled $1.5 billion, consisting of $1.4 billion of 2.375% Senior Notes that matured in March 2018 and $100 million under the Cerro Verde credit facility.
Cash Dividends and Distributions Paid. We paid cash dividends on our common stock totaling $73 million in first-quarter 2019. On March 27, 2019, we declared a quarterly cash dividend of $0.05 per share on our common stock, which was paid on May 1, 2019, to shareholders of record as of April 15, 2019. The declaration of dividends is at the discretion of our Board of Directors (Board) and will depend upon our financial results, cash requirements, future prospects and other factors deemed relevant by our Board.
Cash dividends and distributions paid to noncontrolling interests totaled $9 million in first-quarter 2019 and $80 million in first-quarter 2018. These payments will vary based on the operating results and cash requirements of our consolidated subsidiaries.
CONTRACTUAL OBLIGATIONS
As further discussed in Note 5, during first-quarter 2019, we reduced our December 31, 2018, total debt by $1.2 billion. 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.
CONTINGENCIES
Environmental and Asset Retirement Obligations
Our current and historical operating activities are subject to stringent laws and regulations governing the protection of the environment. We perform a comprehensive annual review of our environmental and asset retirement obligations and also review changes in facts and circumstances associated with these obligations at least quarterly.
There have been no material changes to our environmental and asset retirement obligations since December 31, 2018. Updated cost assumptions, including increases and decreases to cost estimates, changes in the anticipated scope and timing of remediation activities, and settlement of environmental matters may result in additional revisions to certain of our environmental obligations. Refer to Note 12 in our 2018 Form 10-K, for further information regarding our environmental and asset retirement obligations.

Litigation and Other Contingencies
Other than as discussed in Note 8, there have been no material changes to our contingencies associated with legal proceedings, environmental and other matters since December 31, 2018. Refer to Note 12 and “Legal Proceedings” contained in Part I, Item 3. of our 2018 Form 10-K, as updated by Note 8, for further information regarding legal proceedings, environmental and other matters.
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 per pound of copper in the following tables using both a “by-product” method and a “co-product” method. We use the by-product method in our presentation of gross profit per pound of copper because (i) the majority of our revenues are copper revenues, (ii) we mine ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of our costs to revenues from the copper, gold, molybdenum and other metals we produce and (iv) it is the method used by our management and Board to monitor our mining operations and to compare mining operations in certain industry publications. In the co-product method presentations, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent our metals sales volumes and realized prices change.
We show revenue adjustments for prior period open sales as a separate line item. Because these adjustments do not result from current period sales, these amounts have been reflected separately from revenues on current period
sales. Noncash and other costs, which are removed from site production and delivery costs in the calculation of unit
net cash costs (credits), consist of items such as stock-based compensation costs, start-up costs, inventory adjustments, long-lived asset impairments, restructuring and/or unusual charges. As discussed above, gold, molybdenum and other metal revenues at copper mines are reflected as credits against site production and delivery costs in the by-product method. The following schedules are presentations under both the by-product and co-product methods together with reconciliations to amounts reported in our consolidated financial statements.

CAUTIONARY STATEMENT
Our discussion and analysis contains forward-looking statements in which we discuss our potential future performance. Forward-looking statements are all statements other than statements of historical facts, such as projections or expectations relating to ore grades and milling rates; production and sales volumes; unit net cash costs; operating cash flows; capital expenditures; our expectations regarding our share of PT-FI’s net 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 new framework established by the Ministry of Environment and Forestry; exploration efforts and results; development and production activities, rates and costs; liquidity; tax rates; export quotas and duties; the impact of copper, gold and molybdenum price changes; the impact of deferred intercompany profits on earnings; reserve estimates; 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; production rates; timing of shipments; results of feasibility studies; potential inventory adjustments; potential impairment of long-lived mining assets; the potential effects of violence in Indonesia generally and in the province of Papua; the Indonesian government’s approval of an increase in PT-FI's export quota for the current export period, which ends March 8, 2020, and 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; labor relations; weather- and climate-related risks; environmental risks; litigation results; 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.
