NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
NOTE 1. GENERAL INFORMATION
The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by generally accepted accounting principles (GAAP) in the United States (U.S.). Therefore, this information should be read in conjunction with Freeport-McMoRan Inc.’s (FCX) consolidated financial statements and notes contained in its annual report on Form 10-K for the year ended December 31, 2016. The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. With the exception of the accounting for discontinued operations and assets held for sale, all such adjustments are, in the opinion of management, of a normal recurring nature. As a result of FCX’s sale of its interest in TF Holdings Limited (TFHL), FCX has reported TFHL as discontinued operations for all periods presented in the unaudited consolidated financial statements (refer to Note 2). Operating results for the three-month period ended March 31, 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.
Oil and Gas Properties. In first-quarter 2016, FCX Oil & Gas LLC (FM O&G, a wholly owned subsidiary of FCX) determined the carrying values of certain of its unevaluated properties were impaired as of March 31, 2016. As a result, FM O&G transferred $3.1 billion of costs associated with unevaluated properties to the full cost pool, mostly reflecting impairment of the carrying values of unevaluated properties. Combined with the impact of the reduction in twelve-month historical prices and reserve revisions in first-quarter 2016, net capitalized costs exceeded the related ceiling test limitation under full cost accounting rules, which resulted in the recognition of a $3.8 billion impairment charge. Refer to Note 1 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.
NOTE 2. DISPOSITIONS
TF Holdings Limited - Discontinued Operations. FCX had a 70 percent interest in TFHL, which owns 80 percent of Tenke Fungurume Mining S.A. (TFM or Tenke) located in the Democratic Republic of Congo (DRC). On November 16, 2016, FCX completed the sale of its interest in TFHL to China Molybdenum Co., Ltd. (CMOC) for $2.65 billion in cash (before closing adjustments) and contingent consideration of up to $120 million in cash, consisting of $60 million if the average copper price exceeds $3.50 per pound and $60 million if the average cobalt price exceeds $20 per pound, both during calendar years 2018 and 2019. The contingent consideration is considered a derivative, and at March 31, 2017, the related fair value of $49 million was recorded in other assets on the consolidated balance sheets. During first-quarter 2017, the fair value of the contingent consideration derivative increased by $36 million, primarily resulting from higher cobalt prices, and was recorded in net income (loss) from discontinued operations.
In accordance with accounting guidance, FCX has reported the results of operations of TFHL as discontinued operations in the consolidated statements of operations. The consolidated statements of cash flows are reported on a combined basis without separately presenting discontinued operations.

a. | In accordance with accounting guidance, amounts are net of recognition (eliminations) of intercompany sales totaling $9 million in first-quarter 2017 and $(32) million in first-quarter 2016.

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

c. | Includes a $36 million gain associated with the change in the fair value of contingent consideration.

Cash flows from discontinued operations included in the consolidated statements of cash flows for the three months ended March 31, 2016, follow (in millions):

Net cash provided by operating activities |  | $ | 89 |
Net cash used in investing activities |  | (36 | )
Net cash used in financing activities |  | (3 | )
Increase in cash and cash equivalents in assets held for sale |  | $ | 50 |

Assets Held for Sale. FCX intends to sell its interest in Freeport Cobalt and the Kisanfu exploration project in the DRC. Freeport Cobalt includes the large-scale cobalt refinery in Kokkola, Finland, and the related sales and marketing business, in which FCX owns an effective 56 percent interest. Kisanfu is a copper and cobalt exploration project, located near Tenke, in which FCX holds a 100 percent interest. The assets and liabilities of Freeport Cobalt and Kisanfu are classified as held for sale in the consolidated balances sheets.
Oil and Gas Operations. On March 17, 2017, FM O&G sold property interests in the Madden area in central Wyoming for cash consideration of $17.5 million, before closing adjustments. Under the full cost accounting rules, the sale resulted in recognition of a $17 million gain in first-quarter 2017 because the reserves associated with the Madden properties were significant to the full cost pool.

NOTE 3. EARNINGS PER SHARE
FCX calculates its basic net income (loss) per share of common stock under the two-class method and calculates its diluted net income (loss) per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income (loss) per share of common stock was computed by dividing net income (loss) attributable to common stockholders (after deducting accumulated dividends and undistributed earnings to participating securities) by the weighted-average shares of common stock outstanding during the period. Diluted net income (loss) per share of common stock was calculated by including the basic weighted-average shares of common stock outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be anti-dilutive.
A reconciliation of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted net income (loss) per share follows (in millions, except per share amounts):

a. | Excludes 10 million shares associated with outstanding stock options with exercise prices less than the average market price of FCX’s common stock and restricted stock units that were anti-dilutive.

Outstanding stock options with exercise prices greater than the average market price of FCX’s common stock during the period are excluded from the computation of diluted net income (loss) per share of common stock. Stock options for 44 million shares of common stock were excluded for first-quarter 2017 and 47 million for first-quarter 2016.

NOTE 5. INCOME TAXES
Variations in the relative proportions of jurisdictional income result in fluctuations to FCX’s consolidated effective income tax rate. FCX’s consolidated effective income tax rate was 40 percent for first-quarter 2017 and (2) percent for first-quarter 2016. Geographic sources of FCX’s provision for income taxes follow (in millions):

| Three Months Ended |
| March 31, |
| 2017 |  | 2016 |
U.S. operations | $ | (7 | ) |  | $ | 11 |  |
International operations | (167 | ) |  | (88 | ) |
Total | $ | (174 | ) |  | $ | (77 | ) |

Applicable accounting standards require that FCX estimate an annual effective tax rate and apply that rate to each year-to-date interim period. However, an exception is provided to exclude tax jurisdictions from the annual effective tax rate where losses are expected to be generated for which no tax benefit will be realized. Accordingly, U.S. operations have been excluded from the calculation of the estimated annual effective tax rate used to determine FCX’s income tax provision at March 31, 2017.
As a result of the impairment to U.S. oil and gas properties, FCX recorded tax charges of $1.4 billion in first-quarter 2016 to establish a valuation allowance primarily against U.S. federal and state deferred tax assets that will not generate a future benefit. FCX’s consolidated effective income tax rate was 34 percent in first-quarter 2016 excluding these tax charges.

At March 31, 2017, there were no borrowings outstanding and $39 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.
During first-quarter 2017, FCX’s 2.15% Senior Notes matured, and the $500 million outstanding principal balance was repaid.
Consolidated interest expense from continuing operations (excluding capitalized interest) totaled $195 million in first-quarter 2017 and $218 million in first-quarter 2016. Capitalized interest added to property, plant, equipment and mine development costs, net, totaled $28 million in first-quarter 2017 and $20 million in first-quarter 2016. Capitalized interest added to oil and gas properties not subject to amortization totaled $7 million in first-quarter 2016 (none in first-quarter 2017).
NOTE 7. FINANCIAL INSTRUMENTS
FCX does not purchase, hold or sell derivative financial instruments unless there is an existing asset or obligation, or it anticipates a future activity that is likely to occur and will result in exposure to market risks, which FCX intends to offset or mitigate. FCX does not enter into any derivative financial instruments for speculative purposes, but has entered into derivative financial instruments in limited instances to achieve specific objectives. These objectives principally relate to managing risks associated with commodity price changes, foreign currency exchange rates and interest rates.
Commodity Contracts. From time to time, FCX has entered into derivative contracts to hedge the market risk associated with fluctuations in the prices of commodities it purchases and sells. Derivative financial instruments used by FCX to manage its risks do not contain credit risk-related contingent provisions. As of March 31, 2017, and December 31, 2016, FCX had no price protection contracts relating to its mine production. A discussion of FCX’s derivative contracts and programs follows.

Derivatives Designated as Hedging Instruments – Fair Value Hedges
Copper Futures and Swap Contracts. Some of FCX’s U.S. copper rod customers request a fixed market price instead of the Commodity Exchange Inc. (COMEX) average copper price in the month of shipment. FCX hedges this price exposure in a manner that allows it to receive the COMEX average price in the month of shipment while the customers pay the fixed price they requested. FCX accomplishes this by entering into copper futures or swap contracts. Hedging gains or losses from these copper futures and swap contracts are recorded in revenues. FCX did not have any significant gains or losses resulting from hedge ineffectiveness during the three-month periods ended March 31, 2017 and 2016. At March 31, 2017, FCX held copper futures and swap contracts that qualified for hedge accounting for 48 million pounds at an average contract price of $2.56 per pound, with maturities through September 2018.

Derivatives Not Designated as Hedging Instruments
Embedded Derivatives. As described in Note 1 to FCX’s annual report on Form 10-K for the year ended December 31, 2016, under “Revenue Recognition,” certain FCX copper concentrate, copper cathode and gold sales contracts provide for provisional pricing primarily based on the London Metal Exchange (LME) copper price or the COMEX copper price and the London Bullion Market Association (London) gold price at the time of shipment as specified in the contract. Similarly, FCX purchases copper under contracts that provide for provisional pricing. FCX applies the normal purchases and normal sales scope exception in accordance with derivatives and hedge accounting guidance to the host sales agreements since the contracts do not allow for net settlement and always result in physical delivery. Sales and purchases with a provisional sales price contain an embedded derivative (i.e., the price settlement mechanism is settled after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale or purchase of the metals contained in the concentrate or cathode at the then-current LME or COMEX copper price or the London gold price as defined in the contract. Mark-to-market price fluctuations from these embedded derivatives related to continuing operations are recorded through the settlement date and are reflected in revenues for sales contracts and in cost of sales as production and delivery costs for purchase contracts. Mark-to-market price fluctuations associated with embedded derivatives for discontinued operations, which were minimal, are included in discontinued operations for all periods presented in these financial statements.
A summary of FCX’s embedded derivatives at March 31, 2017, follows:

| Open Positions |  | Average Price Per Unit |  | Maturities Through
|  | Contract |  | Market |

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, 2017, Atlantic Copper held net copper forward sales contracts for 8 million pounds at an average contract price of $2.64 per pound, with maturities through May 2017.

Credit Risk. FCX is exposed to credit loss when financial institutions with which FCX 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, 2017, the maximum amount of credit exposure associated with derivative transactions was $26 million.
Other Financial Instruments. Other financial instruments include cash and cash equivalents, accounts receivable, restricted cash, investment securities, legally restricted funds, accounts payable and accrued liabilities, and long-term debt. The carrying value for cash and cash equivalents (which included time deposits of $1.1 billion at March 31, 2017, and $64 million at December 31, 2016), accounts receivable, restricted cash, and accounts payable and accrued liabilities approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 8 for the fair values of investment securities, legally restricted funds and long-term debt).
In addition, FCX has contingent consideration related to its sales of assets and contingent liabilities related to the settlement of FM O&G’s drilling rig contracts (refer to Note 8 for the related fair value). Refer to Note 2 (contingent consideration) and Note 13 (contingent liabilities) of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion of these instruments.
NOTE 8. FAIR VALUE MEASUREMENT
Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). FCX recognizes transfers between levels at the end of the reporting period. FCX did not have any significant transfers in or out of Level 1, 2 or 3 for first-quarter 2017.

Valuation Techniques. The U.S. core fixed income fund is valued at net asset value (NAV). The fund strategy seeks total return consisting of income and capital appreciation primarily by investing in a broad range of investment-grade debt securities, including U.S. government obligations, corporate bonds, mortgage-backed securities, asset-backed securities and money market instruments. There are no restrictions on redemptions (which are usually within one business day of notice).
Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.
Equity securities are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy.
Fixed income securities (government securities, corporate bonds, asset-backed securities, collateralized mortgage-backed securities and municipal bonds) are valued using a bid-evaluation price or a mid-evaluation price. A bid-evaluation price is an estimated price at which a dealer would pay for a security. A mid-evaluation price is the average of the estimated price at which a dealer would sell a security and the estimated price at which a dealer would pay for a security. These evaluations are based on quoted prices, if available, or models that use observable inputs and, as such, are classified within Level 2 of the fair value hierarchy.
FCX’s embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales are valued using only quoted monthly LME or COMEX copper forward prices and the London gold forward price at each reporting date based on the month of maturity (refer to Note 7 for further discussion); however, FCX’s contracts themselves are not traded on an exchange. As a result, these derivatives are classified within Level 2 of the fair value hierarchy.
FCX’s derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 7 for further discussion). Certain of these contracts are traded on the over-the-counter market and are classified within Level 2 of the fair value hierarchy based on COMEX and LME forward prices.
The fair value of contingent consideration for the sales of TFHL and onshore California oil and gas properties is calculated based on average commodity price forecasts through applicable maturity dates using a Monte Carlo simulation model. The models use various observable inputs, including Brent crude oil forward prices, historical copper and cobalt prices, volatilities, discount rates and settlement terms. As a result, these contingent consideration assets are classified within Level 2 of the fair value hierarchy.
The fair value of contingent consideration for the sale of Deepwater GOM oil and gas properties is calculated based on a discounted cash flow model using inputs that include third-party reserve estimates, production rates, production timing and discount rates. Because significant inputs are not observable in the market, the contingent consideration is classified within Level 3 of the fair value hierarchy.
The fair value of contingent payments for the settlements of drilling rig contracts is calculated based on the average price forecasts of West Texas Intermediate (WTI) crude oil over the 12-month period ending June 30, 2017, using a mean-reverting model. The model uses various observable inputs, including WTI crude oil forward prices, volatilities, discount rate and settlement terms. As a result, these contingent payments are classified within Level 2 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, 2017, as compared to those techniques used at December 31, 2016.

NOTE 9. CONTINGENCIES AND COMMITMENTS
Litigation. During first-quarter 2017, there were no significant updates to previously reported legal proceedings included in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.
Tax and Other Matters
Cerro Verde Royalty Dispute
As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, SUNAT, the Peru national tax authority, has assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006, for the period December 2006 to December 2007, the years 2008, 2009 and 2010, and the period January 2011 to September 2011. SUNAT may make additional assessments for mining royalties and associated penalties and interest for the period from October 2011 through December 2013, which Cerro Verde will contest. As of March 31, 2017, FCX estimates the total exposure associated with these mining royalties for the period from December 2006 through December 2013 approximates $573 million (based on the exchange rate as of March 31, 2017), including estimated accumulated interest and penalties. No charges have been recorded for these assessments as of March 31, 2017, because Cerro Verde believes its 1998 stability agreement exempts it from these royalties and believes any payments will be recoverable.
Other Peru Tax Matters
There were no significant changes to other Peru tax matters during first-quarter 2017 (refer to Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016).
Indonesia Tax Matters
The following information includes a discussion of updates to previously reported Indonesia tax matters included in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.
PT-FI received assessments from the local regional tax authority in Papua, Indonesia, for additional taxes and penalties related to surface water taxes for the period from January 2011 through March 2017. PT-FI has filed or will file objections to these assessments. The aggregate amount of assessments for additional taxes and penalties for the period from January 2011 through July 2015 was $380 million (based on the exchange rate as of March 31, 2017, and including $229 million in penalties). The aggregate amount of assessments received from August 2015 through March 2017 was an additional $109 million, including penalties (based on the exchange rate as of March 31, 2017). No charges have been recorded for these assessments as of March 31, 2017, because PT-FI believes its Contract of Work (COW) exempts it from these payments and that it has the right to contest these assessments in the Indonesia Tax Court and ultimately the Indonesia Supreme Court. As of May 5, 2017, PT-FI has not paid and does not intend to pay these assessments unless there is a mechanism established to secure a refund for any such payments upon the final court decision.
Indonesia Mining Contract. The following information includes updates to the discussion of PT-FI’s COW included in Note 13 of FCX’s annual report on Form 10-K for the year ended December 31, 2016.
In January and February 2017, the Indonesian government issued new regulations to address exports of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. The new regulations permit the continuation of copper concentrate exports for a five-year period through January 2022, subject to various conditions, including conversion from a contract of work to a special operating license (known as an IUPK, which does not provide the same level of protections of a contract of work), commitment to completion of smelter construction in five years and payment of export duties to be determined by the Ministry of Finance. In addition, the new regulations enable application for extension of operating rights five years before expiration of the IUPK and require foreign IUPK holders to divest 51 percent to Indonesian interests no later than the tenth year of production. Export licenses would be valid for one-year periods, subject to review every six months, depending on smelter construction progress.
Following the issuance of the January and February 2017 regulations and discussions with the government, PT-FI advised the Indonesian government that it was prepared to convert its COW to an IUPK, subject to obtaining an investment stability agreement providing equivalent rights with the same level of legal and fiscal certainty enumerated under its COW, and provided that the COW would remain in effect until it is replaced by a mutually satisfactory alternative. PT-FI also committed to commence construction of a new smelter during a five-year timeframe after approval of the extension of its long-term operating rights.

In mid-February 2017, pursuant to the COW’s dispute resolution process, PT-FI provided formal notice to the Indonesian government of an impending dispute listing the government's breaches and violations of the COW.
In late March 2017, the Indonesian government amended its regulations to enable PT-FI to retain its COW until replaced with an IUPK accompanied by an investment stability agreement, and to grant PT-FI a temporary IUPK through October 10, 2017, to enable concentrate exports during this period. In April 2017, PT-FI entered into a Memorandum of Understanding with the Indonesian government confirming that the COW would continue to be valid and honored until replaced by a mutually agreed IUPK and investment stability agreement. PT-FI will continue to pay a 5 percent export duty during this period.
On April 21, 2017, the Indonesian government issued a permit to PT-FI to enable exports to resume for a six-month period and PT-FI began loading export shipments, PT-FI plans to ramp up its production to full rates during second-quarter 2017.
As a result of the first-quarter 2017 regulatory restrictions and uncertainties regarding long-term investment stability, PT-FI has taken actions to adjust its cost structure, reduce its workforce and slow investments in its underground development projects and new smelter.
PT-FI and the Indonesian government have commenced negotiations on the conversion of PT-FI's COW to an IUPK accompanied by an investment stability agreement with the objective of providing a mutually acceptable long-term investment framework. In addition to negotiating a stability agreement, the parties are also discussing requirements for the construction of a new smelter and the government’s request for divestment.
NOTE 10. BUSINESS SEGMENTS
FCX has organized its mining operations into four primary divisions – North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX’s reportable segments, which include the Morenci, Cerro Verde and Grasberg (Indonesia Mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining.
FCX’s reportable segments previously included U.S. Oil & Gas operations. During 2016, FCX completed the sales of its Deepwater Gulf of Mexico, onshore California and Haynesville oil and gas properties, and in first-quarter 2017, completed the sale of its Madden property interests. The results of FCX’s U.S. oil and gas operations no longer qualify as a reportable segment, and oil and gas results for all periods presented have been included in Corporate, Other & Eliminations in the following tables. Refer to Note 2 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for additional information.
Intersegment sales between FCX’s mining operations are based on similar arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums.
FCX defers recognizing profits on sales from its mines to other divisions, including Atlantic Copper (FCX’s wholly owned smelter and refinery in Spain) and on 25 percent of PT-FI’s sales to PT Smelting (PT-FI’s 25 percent-owned smelter and refinery in Indonesia), until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX’s net deferred profits and quarterly earnings.
FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level (included in Corporate, Other & Eliminations), whereas foreign income taxes are recorded and managed at the applicable country level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs, along with some selling, general and administrative costs, are not allocated to the operating divisions or individual segments. Accordingly, the following segment information reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

REVIEW REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF
FREEPORT-McMoRan INC.
We have reviewed the consolidated balance sheet of Freeport-McMoRan Inc. as of March 31, 2017, and the related consolidated statements of operations, comprehensive income (loss) and cash flows for the three-month periods ended March 31, 2017 and 2016, and the consolidated statement of equity for the three-month period ended March 31, 2017. These financial statements are the responsibility of the Company’s management.
We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
Based on our review, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Freeport-McMoRan Inc. as of December 31, 2016, and the related consolidated statements of operations, comprehensive loss, cash flows and equity for the year then ended (not presented herein) and we expressed an unqualified audit opinion on those consolidated financial statements in our report dated February 24, 2017. In our opinion, the accompanying consolidated balance sheet of Freeport-McMoRan Inc. as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

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

In Management’s Discussion and Analysis of Financial Condition and Results of Operations, “we,” “us” and “our” refer to Freeport-McMoRan Inc. (FCX) and its consolidated subsidiaries. You should read this discussion in conjunction with our financial statements, the related Management’s Discussion and Analysis of Financial Condition and Results of Operations and the discussion of our Business and Properties in our annual report on Form 10-K for the year ended December 31, 2016, filed with the United States (U.S.) Securities and Exchange Commission (SEC). The results of operations reported and summarized below are not necessarily indicative of future operating results (refer to “Cautionary Statement” for further discussion). References to “Notes” are Notes included in our Notes to Consolidated Financial Statements. Throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations, all references to earnings or losses per share are on a diluted basis. Additionally, in accordance with accounting guidelines, TF Holdings Limited (TFHL), through which we held an interest in the Tenke Fungurume (Tenke) mine until it was sold on November 16, 2016, is reported as a discontinued operation for all periods presented.
OVERVIEW
We are a leading international mining company with headquarters in Phoenix, Arizona. We operate large, long-lived, geographically diverse assets with significant proven and probable reserves of copper, gold and molybdenum. We are the world’s largest publicly traded copper producer. Our portfolio of assets includes the Grasberg minerals district in Indonesia, one of the world’s largest copper and gold deposits; and significant mining operations in the Americas, including the large-scale Morenci minerals district in North America and the Cerro Verde operation in South America.
Net income (loss) attributable to common stock totaled $228 million in first-quarter 2017 and $(4.2) billion in first-quarter 2016, which included a charge of $3.8 billion for the impairment of oil and gas properties. First-quarter 2017, compared with the 2016 period, benefited from higher copper and molybdenum prices and lower depreciation, depletion and amortization (DD&A) expense, partly offset by lower copper and gold sales volumes. Refer to “Consolidated Results” for further discussion.
At March 31, 2017, we had $4.0 billion in consolidated cash and cash equivalents and $15.4 billion in total debt. We had no borrowings and $3.5 billion available under our revolving credit facility. Refer to Note 6 for further discussion of debt.
We continue to manage production, exploration and administrative costs and capital spending and, subject to commodity prices and operational results, expect to generate cash flows for further debt reduction during 2017.
We have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. In addition to debt reduction plans, we are pursuing opportunities to enhance net present values, and we continue to advance studies for future development of our copper resources, the timing of which is dependent on market conditions.
In late March 2017, the Indonesian government amended its regulations to enable PT Freeport Indonesia (PT-FI) to retain its Contract of Work (COW) until replaced with a special operating license (known as an IUPK) accompanied by an investment stability agreement, and to grant PT-FI a temporary IUPK through October 10, 2017, to enable concentrate exports during this period. On April 21, 2017, PT-FI resumed concentrate exports, which had been suspended since January 12, 2017. Refer to “Operations – Indonesia Mining” for further discussion.
OUTLOOK
We view the long-term outlook for our business positively, supported by limitations on supplies of copper and by the requirements for copper in the world’s economy. Our financial results vary as a result of fluctuations in market prices primarily for copper, gold and molybdenum, as well as other factors. World market prices for these commodities have historically fluctuated and are affected by numerous factors beyond our control. Because we cannot control the price of our products, the key measures that management focuses on in operating our business are sales volumes, unit net cash costs, operating cash flow and capital expenditures.
Projections for 2017 and other forward looking statements in this quarterly report on Form 10-Q assume normal operating rates at PT-FI beginning mid-April 2017, and the resolution or completion of negotiations with the Indonesian government on the conversion of PT-FI’s COW to an IUPK accompanied by an investment stability

agreement by October 10, 2017. Refer to “Operations – Indonesia Mining” for further discussion of Indonesia regulatory matters, which may have a significant impact on future results.
Sales Volumes
Following are our projected consolidated sales volumes for the year 2017:

Copper (millions of recoverable pounds): |  |
North America copper mines | 1,490 |  |
South America mining | 1,240 |  |
Indonesia mining | 1,135 |  |
Total | 3,865 |  |
Gold (thousands of recoverable ounces) | 1,917 |  |
Molybdenum (millions of recoverable pounds) | 93 |  | a

a. | Projected molybdenum sales include 35 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 2017 are expected to approximate 1.0 billion pounds of copper, 440 thousand ounces of gold and 24 million pounds of molybdenum.
Projected sales volumes are dependent on operational performance and other factors. For other important factors that could cause results to differ materially from projections, refer to “Cautionary Statement.”
Unit Net Cash Costs
Assuming average prices of $1,250 per ounce of gold and $9.00 per pound of molybdenum for the remainder of 2017 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 $1.08 per pound of copper for the year 2017. The impact of price changes for remainder of 2017 on consolidated unit net cash costs would approximate $0.02 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, a return to normal operating rates in Indonesia and assuming average prices of $2.50 per pound of copper, $1,250 per ounce of gold and $9.00 per pound of molybdenum for the remainder of 2017, consolidated operating cash flows are estimated to approximate $4.0 billion for the year 2017 (including $1.0 billion in working capital sources and changes in other tax payments). Projected consolidated operating cash flows for the year 2017 also reflect an estimated income tax provision of $1.2 billion (refer to “Consolidated Results – Income Taxes” for further discussion of our projected income tax rate for the year 2017). The impact of price changes during the remainder of 2017 on operating cash flows would approximate $275 million for each $0.10 per pound change in the average price of copper, $65 million for each $50 per ounce change in the average price of gold and $70 million for each $2 per pound change in the average price of molybdenum.
Consolidated Capital Expenditures
Consolidated capital expenditures are expected to approximate $1.6 billion for the year 2017, including $0.9 billion for major mining projects primarily associated with underground development activities at Grasberg. As a result of regulatory uncertainty, PT-FI slowed investments in its underground development projects during first-quarter 2017. If PT-FI is unable to reach an agreement with the Indonesian government on its long-term mining rights, we intend to significantly reduce or defer investments in underground development projects.

MARKETS
World prices for copper, gold and molybdenum can fluctuate significantly. During the period from January 2007 through March 2017, the London Metal Exchange (LME) spot copper price varied from a low of $1.26 per pound in 2008 to a record high of $4.60 per pound in 2011; the London Bullion Market Association (London) PM gold price fluctuated from a low of $608 per ounce in 2007 to a record high of $1,895 per ounce in 2011; and the Metals Week Molybdenum Dealer Oxide weekly average price ranged from a low of $4.46 per pound in 2015 to a high of $33.88 per pound in 2008. Copper, gold and molybdenum prices are affected by numerous factors beyond our control as described further in “Risk Factors” contained in Part I, Item 1A. of our annual report on Form 10-K for the year ended December 31, 2016.
This graph presents LME spot copper prices and the combined reported stocks of copper at the LME, Commodity Exchange Inc. (COMEX), a division of the New York Mercantile Exchange (NYMEX), and the Shanghai Futures Exchange from January 2007 through March 2017. Since mid-2014, copper prices have declined because of concerns about slowing growth rates in China, a stronger U.S. dollar and a broad-based decline in commodity prices, but began to improve starting in fourth-quarter 2016. During first-quarter 2017, LME spot copper prices ranged from a low of $2.49 per pound to a high of $2.79 per pound, averaged $2.65 per pound, and closed at $2.65 per pound on March 31, 2017. The LME spot copper price was $2.58 per pound on April 28, 2017.
We believe the underlying long-term fundamentals of the copper business remain positive, supported by the significant role of copper in the global economy and a challenging long-term supply environment attributable to difficulty in replacing output of existing large mines with new production sources. Future copper prices are expected to be volatile and are likely to be influenced by demand from China and emerging markets, as well as economic activity in the U.S. and other industrialized countries, the timing of the development of new supplies of copper and production levels of mines and copper smelters.

Revenues
Consolidated revenues totaled $3.3 billion in first-quarter 2017, compared with $3.2 billion in first-quarter 2016. Revenues from our mining operations primarily include the sale of copper concentrate, copper cathode, copper rod, gold and molybdenum. Revenues from our oil and gas operations include the sale of oil, natural gas and natural gas liquids (NGLs). Following is a summary of changes in our consolidated revenues between periods (in millions):

| Three Months Ended March 31
Revenues - 2016 period | $ | 3,242 |
(Lower) higher sales volumes: |
Copper | (418 | )
Gold | (23 | )

Higher revenues from purchased copper | 98 |
Higher Atlantic Copper revenues | 35 |
Other, including intercompany eliminations | 79 |
Revenues - 2017 period | $ | 3,341 |

Sales Volumes. Consolidated copper sales decreased to 809 million pounds in first-quarter 2017, compared with 1.0 billion pounds in first-quarter 2016, primarily reflecting lower volumes from North America mostly related to lower ore grades and mining rates, and from Indonesia as a result of regulatory restrictions on PT-FI's concentrate exports.
Consolidated gold sales volumes totaled 182 thousand ounces in first-quarter 2017 and 201 thousand ounces in first-quarter 2016. Lower gold sales volumes in first-quarter 2017, compared with the 2016 period, primarily reflects lower volumes from Indonesia as a result of regulatory restrictions on PT-FI's concentrate exports.
Consolidated molybdenum sales volumes increased to 24 million pounds in first-quarter 2017, compared with 17 million pounds in first-quarter 2016, primarily reflecting higher demand.
Oil and gas sales volumes of 1.6 MMBOE in first-quarter 2017 were 87 percent lower than oil and gas sales volumes of 12.1 MMBOE in first-quarter 2016, primarily reflecting the sales of significant oil and gas properties in 2016.
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 2017 average realized prices, compared with first-quarter 2016, were 22 percent higher for copper, less than 1 percent higher for gold and 14 percent higher for molybdenum. Refer to “Markets” for further discussion.
Provisionally Priced Copper Sales. Impacts of net adjustments for prior period provisionally priced sales primarily relate to copper sales. Substantially all of our copper concentrate and cathode sales contracts provide final copper pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted LME monthly average spot copper prices. We receive market prices based on prices in the specified future period, which results in price fluctuations recorded through revenues until the date of settlement. We record revenues and invoice customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on our provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is

Table of Contents
recorded each reporting period until the date of final pricing. Accordingly, in times of rising copper prices, our revenues benefit from adjustments to the final pricing of provisionally priced sales pursuant to contracts entered into in prior periods; in times of falling copper prices, the opposite occurs. Favorable impacts of net adjustments to prior periods’ provisionally priced copper sales from continuing operations totaled $91 million in first-quarter 2017 and $9 million in first-quarter 2016.
At March 31, 2017, we had provisionally priced copper sales at our copper mining operations totaling 260 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $2.65 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, 2017, provisional price recorded would have an approximate $8 million effect on our 2017 net income attributable to common stock. The LME spot copper price was $2.58 per pound on April 28, 2017.
Treatment Charges. Revenues from our South America and Indonesia concentrate sales are recorded net of treatment charges. Lower treatment charges in first-quarter 2017, compared with first-quarter 2016, primarily reflect lower sales volumes from Indonesia as a result of the regulatory restrictions on PT-FI's concentrate exports.
Purchased Copper. We purchase copper cathode primarily for processing by our Rod & Refining operations. In addition to higher copper prices, we had higher purchased copper volumes of 58 million pounds in first-quarter 2017, compared with 27 million pounds in first-quarter 2016.
Atlantic Copper Revenues. Atlantic Copper revenues totaled $458 million in first-quarter 2017 and $423 million in first-quarter 2016. Revenues in first-quarter 2017, compared with first-quarter 2016, reflect higher copper prices.
Production and Delivery Costs
Lower consolidated production and delivery costs of $2.2 billion in first-quarter 2017, compared with $2.5 billion in first-quarter 2016, primarily reflect lower costs at oil and gas operations (including lower charges for drillship settlements/idle rig costs, which were a net credit of $20 million in first-quarter 2017 and a net charge of $165 million in first-quarter 2016) and lower costs at our North America and Indonesia mining operations.
Mining Unit Site Production and Delivery Costs. Site production and delivery costs for our copper mining operations primarily include labor, energy and commodity-based inputs, such as sulphuric acid, reagents, liners, tires and explosives. Consolidated unit site production and delivery costs (before net noncash and other costs) for our copper mines averaged $1.60 per pound of copper in first-quarter 2017, compared with $1.49 per pound in first quarter of 2016. Higher consolidated unit site production and delivery costs for first-quarter 2017, compared with the 2016 period, primarily reflect lower sales volumes. Refer to “Operations – Unit Net Cash Costs” for further discussion of unit net cash costs associated with our operating divisions and to “Product Revenues and Production Costs” for reconciliations of per pound costs by operating division to production and delivery costs applicable to sales reported in our consolidated financial statements.
Depreciation, Depletion and Amortization
Depreciation will vary under the unit-of-production (UOP) method as a result of changes in sales volumes and the related UOP rates at our individual mines. Consolidated DD&A totaled $389 million in first-quarter 2017 and $662 million in first quarter of 2016. Lower DD&A in first-quarter 2017, compared with the 2016 period, primarily reflects lower DD&A from oil and gas operations resulting from the sales of significant oil and gas properties in 2016.
Impairment of Oil and Gas Properties
Under full cost accounting rules, a “ceiling test” is conducted each quarter to review the carrying value of our oil and gas properties for impairment, which resulted in the recognition of impairment charges totaling $3.8 billion for first-quarter 2016.
Selling, General and Administrative Expenses
Consolidated selling, general and administrative expenses totaled $153 million in first-quarter 2017 and $138 million in first-quarter 2016. Selling, general and administrative expenses include net charges of $21 million for first-quarter 2017 for contract termination costs at our oil and gas operations.
Consolidated selling, general and administrative expenses were net of capitalized general and administrative expenses at our oil and gas operations totaling $28 million in first-quarter 2016.

Table of Contents
Mining Exploration and Research Expenses
Consolidated exploration and research expenses for our mining operations totaled $15 million in first-quarter 2017 and $18 million in first-quarter 2016. Our mining exploration activities are generally associated with our existing mines and focus on opportunities to expand reserves and resources to support development of additional future production capacity. Exploration results continue to indicate opportunities for significant future potential reserve additions in North America and South America. Exploration spending is expected to approximate $70 million for the year 2017.
Environmental Obligations and Shutdown Costs
Environmental obligation costs reflect net revisions to our long-term environmental obligations, which vary from period to period because of changes to environmental laws and regulations, the settlement of environmental matters and/or circumstances affecting our operations that could result in significant changes in our estimates. Shutdown costs include care-and-maintenance costs and any litigation, remediation or related expenditures associated with closed facilities or operations. Net charges for environmental obligations and shutdown costs totaled $27 million in first-quarter 2017 and $10 million in first-quarter 2016.
Net Gain on Sales of Assets
Net gain on sales of assets associated with oil and gas transactions totaled $23 million in first-quarter 2017, including gains of $17 million related to the sale of Madden property interests and $16 million of adjustments related to the December 2016 Deepwater GOM sale, partly offset by adjustments of $10 million to the fair value of the potential $150 million in contingent consideration related to the December 2016 onshore California sale, which in accordance with accounting guidelines will continue to be adjusted through December 31, 2020.
Interest Expense, Net
Consolidated interest expense (excluding capitalized interest and interest expense allocated to discontinued operations) totaled $195 million in first-quarter 2017 and $218 million in first-quarter 2016.
Capitalized interest varies with the level of expenditures for our development projects and average interest rates on our borrowings and totaled $28 million in first-quarter 2017 and $27 million in first-quarter 2016.
Income Taxes
Following is a summary of the approximate amounts used in the calculation of our consolidated income tax provision from continuing operations for the first-quarter s of 2017 and 2016 (in millions, except percentages):

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

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

c. | We adjust our interim provision for income taxes in accordance with applicable accounting rules.

d. | The consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which we operate. Accordingly, variations in the relative proportions of jurisdictional income result in fluctuations to our consolidated effective income tax rate. Assuming achievement of current sales volume and cost estimates and average prices of $2.50 per pound for copper, $1,250 per ounce for gold and $9 per pound for molybdenum for the remainder of 2017, we estimate our consolidated effective tax rate related to continuing operations for the year 2017 will approximate 45 percent and would decrease with higher prices.

Net Income (Loss) from Discontinued Operations
In November 2016, we completed the sale of our interest in TFHL, through which we had an effective 56 percent interest in the Tenke copper and cobalt concessions in the Democratic Republic of Congo (DRC). In accordance with accounting guidelines, the results of TFHL have been reported as discontinued operations for all periods presented. Net income (loss) from discontinued operations totaled $38 million in first-quarter 2017, which primarily reflected adjustments to the fair value of potential contingent consideration related to the sale, and $(4) million in first-quarter 2016. Refer to Note 2 for a summary of the components of income (loss) from discontinued operations.
OPERATIONS
North America Copper Mines
We operate seven open-pit copper mines in North America – Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. All of the North America mining operations are wholly owned, except for Morenci.
We record our undivided joint venture interest in Morenci using the proportionate consolidation method. On May 31, 2016, we completed the sale of an additional 13 percent undivided interest in Morenci. As a result of the transaction, our undivided interest in Morenci was prospectively reduced from 85 percent to 72 percent.
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 market conditions.
Through exploration drilling, we have identified a significant resource at the Lone Star project located near the Safford operation in eastern Arizona. Initial production from Lone Star is being planned from the oxide ores beginning in 2021, which can be processed through existing infrastructure to replace oxide production from Safford. We continue to evaluate longer term opportunities available from the significant sulfide potential in the Lone Star/Safford minerals district.

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 375 million pounds in first-quarter 2017 were lower than first-quarter 2016 sales of 503 million pounds, primarily reflecting lower ore grades and mining rates, timing of shipments, and the impact of the May 2016 sale of an additional 13 percent interest in Morenci.
North America copper sales are estimated to approximate 1.5 billion pounds for the year 2017, compared with 1.8 billion pounds in 2016.
Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.

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

b. | Includes $19 million ($0.05 per pound of copper) for other asset impairment charges at Morenci.

Our North America copper mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.48 per pound of copper in first-quarter 2017 were higher than unit net cash costs of $1.42 per pound in first-quarter 2016, primarily reflecting lower copper sales volumes, partly offset by higher molybdenum credits.
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 $1.53 per pound of copper for the year 2017, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $9.00 per pound for the remainder of 2017. North America’s average unit net cash costs for the year 2017 would change by approximately $0.03 per pound for each $2 per pound change in the average price of molybdenum for the remainder of 2017.
South America Mining
We operate two copper mines in South America – Cerro Verde in Peru (in which we own a 53.56 percent interest) and El Abra in Chile (in which we own a 51 percent interest). These operations are consolidated in our financial statements.
South America mining includes open-pit mining, sulfide ore concentrating, leaching and SX/EW operations. Production from our South America mines is sold as copper concentrate or cathode under long-term contracts. Our South America mines also ship a portion of their copper concentrate inventories to Atlantic Copper. In addition to copper, the Cerro Verde mine produces molybdenum concentrate and silver.

Operating and Development Activities. The Cerro Verde expansion project commenced operations in September 2015 and achieved capacity operating rates during first-quarter 2016. Cerro Verde’s expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. The project expanded the concentrator facilities from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day.
In the second half of 2015, we adjusted operations at our El Abra mine to reduce mining and stacking rates by approximately 50 percent to achieve lower operating and labor costs, defer capital expenditures and extend the life of the existing operations. El Abra continues to operate at reduced rates.
We continue to evaluate a potential large-scale milling operation at El Abra to process additional sulfide material and to achieve higher recoveries. Exploration results in recent years at El Abra indicate a significant sulfide resource, which could potentially support a major mill project. Future investments will depend on technical studies, economic factors and market conditions.
Operating Data. Following is a summary of consolidated operating data for our South America mining operations for the three months ended March 31, 2017 and 2016:

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 309 million pounds in first-quarter 2017 were lower than first-quarter 2016 sales of 323 million pounds. During first-quarter 2017, Cerro Verde's operations were unfavorably impacted by unusually heavy rainfall and a 21-day labor strike. These issues resulted in lower than planned mining rates and a reduction of approximately 80 million pounds of copper in Cerro Verde's estimated 2017 sales volumes.
Copper sales from South America mines are expected to approximate 1.2 billion pounds of copper for the year 2017, compared with 1.3 billion pounds of copper in 2016.
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.

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 $1.53 per pound of copper in first-quarter 2017 were higher than unit net cash costs of $1.40 per pound in first-quarter 2016, primarily reflecting higher milling and mining costs at Cerro Verde and lower volumes, partly offset by higher by-product credits.
Revenues from Cerro Verde’s concentrate sales are recorded net of treatment charges. Accordingly, treatment charges will vary with Cerro Verde’s sales volumes and the price of copper.
Because certain assets are depreciated on a straight-line basis, South America’s unit depreciation rate may vary with asset additions and the level of copper production and sales.
Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to “Consolidated Results – Revenues” for further discussion of adjustments to prior period provisionally priced copper sales.
Average unit net cash costs (net of by-product credits) for our South America mining operations are expected to approximate $1.63 per pound of copper for the year 2017, based on current sales volume and cost estimates and assuming an average price of $9.00 per pound of molybdenum for the remainder of 2017.
Indonesia Mining
Indonesia mining includes PT-FI’s Grasberg minerals district, one of the world’s largest copper and gold deposits, in Papua, Indonesia. We own 90.64 percent of PT-FI, including 9.36 percent owned through our wholly owned subsidiary, PT Indocopper Investama.
PT-FI proportionately consolidates an unincorporated joint venture with Rio Tinto plc (Rio Tinto), under which Rio Tinto has a 40 percent interest in certain assets and a 40 percent interest through 2022 in production exceeding specified annual amounts of copper, gold and silver. Refer to Note 3 in our annual report on Form 10-K for the year ended December 31, 2016, for discussion of our joint venture with Rio Tinto.

Table of Contents
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 2017, approximately half of PT-FI’s concentrate production was sold to PT Smelting, its 25-percent-owned smelter and refinery in Gresik, Indonesia.
Regulatory Matters. In January and February 2017, the Indonesian government issued new regulations to address exports of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. The new regulations permit the continuation of copper concentrate exports for a five-year period through January 2022, subject to various conditions, including conversion from a contract of work to a special operating license (known as an IUPK, which does not provide the same level of protections of a contract of work), commitment to completion of smelter construction in five years and payment of export duties to be determined by the Ministry of Finance. In addition, the new regulations enable application for extension of operating rights five years before expiration of the IUPK and require foreign IUPK holders to divest 51 percent to Indonesian interests no later than the tenth year of production. Export licenses would be valid for one-year periods, subject to review every six months, depending on smelter construction progress.
Following the issuance of the January and February 2017 regulations and discussions with the government, PT-FI advised the Indonesian government that it was prepared to convert its COW to an IUPK, subject to obtaining an investment stability agreement providing equivalent rights with the same level of legal and fiscal certainty enumerated under its COW, and provided that the COW would remain in effect until it is replaced by a mutually satisfactory alternative. PT-FI also committed to commence construction of a new smelter during a five-year timeframe after approval of the extension of its long-term operating rights.
In mid-February 2017, pursuant to the COW’s dispute resolution process, PT-FI provided formal notice to the Indonesian government of an impending dispute listing the government's breaches and violations of the COW.
In late March 2017, the Indonesian government amended the regulations to enable PT-FI to retain its COW until replaced with an IUPK accompanied by an investment stability agreement, and to grant PT-FI a temporary IUPK through October 10, 2017, to enable concentrate exports during this period. In April 2017, PT-FI entered into a Memorandum of Understanding with the Indonesian government confirming that the COW would continue to be valid and honored until replaced by a mutually agreed IUPK and investment stability agreement. PT-FI will continue to pay a 5.0 percent export duty during this period.
On April 21, 2017, the Indonesian government issued a permit to PT-FI to enable exports to resume for a six-month period, and PT-FI began loading export shipments. PT-FI plans to ramp up its production to full rates during second-quarter 2017.
As a result of the first-quarter 2017 regulatory restrictions and uncertainties regarding long-term investment
stability, PT-FI has taken actions to adjust its cost structure, reduce its workforce and slow investments in its
underground development projects and new smelter.
PT-FI and the Indonesian government have commenced negotiations on the conversion of PT-FI’s COW to an IUPK accompanied by an investment stability agreement with the objective of providing a mutually acceptable long-term investment framework. In addition to negotiating a stability agreement, the parties are also discussing requirements for the construction of a new smelter and the government’s request for divestment.
We cannot predict whether PT-FI will be successful in reaching a satisfactory agreement on the terms of its long-term mining rights. Refer to “Risk Factors” contained in Part I, Item 1A. of our annual report on Form 10-K for the year ended December 31, 2016, for further discussion of risks associated with our operations in Indonesia.
Operating and Development Activities. PT-FI is currently mining the final phase of the Grasberg open pit, which contains high copper and gold ore grades. PT-FI expects to mine high-grade ore over the next several quarters prior to transitioning to the Grasberg Block Cave underground mine in late 2018.
PT-FI has several projects in the Grasberg minerals district related to the development of its large-scale, long-lived, high-grade underground ore bodies. In aggregate, these underground ore bodies are expected to produce large-scale quantities of copper and gold following the transition from the Grasberg open pit. As a result of regulatory uncertainty, PT-FI has slowed investments in its underground development projects during first-quarter 2017. Assuming an agreement is reached to support PT-FI’s long-term investment plans, estimated annual capital spending on these projects would average $1.0 billion per year ($0.8 billion per year net to PT-FI) over the next five

Table of Contents
years. Considering the long-term nature and size of these projects, actual costs could vary from these estimates. In response to market conditions and Indonesian regulatory uncertainty, the timing of these expenditures continues to be reviewed. If PT-FI is unable to reach agreement with the Indonesian government on its long-term mining rights, we intend to significantly reduce or defer investments in underground development projects.
The following provides additional information on the continued development of the Common Infrastructure project, the Grasberg Block Cave underground mine and the Deep Mill Level Zone (DMLZ) ore body that lies below the Deep Ore Zone (DOZ) underground mine. Our current plans and mineral reserves in Indonesia assume that PT-FI’s long-term mining rights will be extended through 2041, as stated in the COW.
Common Infrastructure and Grasberg Block Cave Mine. In 2004, PT-FI commenced its Common Infrastructure project to provide access to its large undeveloped underground ore bodies located in the Grasberg minerals district through a tunnel system located approximately 400 meters deeper than its existing underground tunnel system. In addition to providing access to our underground ore bodies, the tunnel system will enable PT-FI to conduct future exploration in prospective areas associated with currently identified ore bodies. The tunnel system was completed to the Big Gossan terminal, and the Big Gossan mine was brought into production in 2010. The Big Gossan underground mine is currently in care-and-maintenance. Development of the DMLZ and Grasberg Block Cave underground mines is advancing using the Common Infrastructure project tunnels as access.
The Grasberg Block Cave underground mine accounts for approximately half of our recoverable proven and probable reserves in Indonesia. Production from the Grasberg Block Cave mine is expected to commence in late 2018, following the end of mining of the Grasberg open pit. Targeted production rates once the Grasberg Block Cave mining operation reaches full capacity are expected to approximate 160,000 metric tons of ore per day. PT-FI is reviewing its operating plans to determine the optimum mine plan for the Grasberg Block Cave.
Aggregate mine development capital for the Grasberg Block Cave mine and associated Common Infrastructure is expected to approximate $6.3 billion (incurred between 2008 and 2022), with PT-FI’s share totaling approximately $5.8 billion. Aggregate project costs totaling $3.0 billion have been incurred through March 31, 2017, including $149 million during first-quarter 2017. As a result of regulatory uncertainty, PT-FI has slowed investments in its underground development projects during first-quarter 2017. If PT-FI is unable to reach agreement with the Indonesian government on its long-term mining rights, we intend to significantly reduce or defer investments in underground development projects.
DMLZ. The DMLZ ore body lies below the DOZ mine at the 2,590-meter elevation and represents the downward continuation of mineralization in the Ertsberg East Skarn system and neighboring Ertsberg porphyry. In September 2015, PT-FI initiated pre-commercial production that represents ore extracted during the development phase for the purpose of obtaining access to the ore body. Targeted production rates once the DMLZ underground mine reaches full capacity are expected to approximate 80,000 metric tons of ore per day in 2022.
Drilling efforts continue to determine the extent of the ore body. Aggregate mine development capital costs for the DMLZ underground mine are expected to approximate $3.2 billion (incurred between 2009 and 2021), with PT-FI’s share totaling approximately $1.9 billion. Aggregate project costs totaling $1.9 billion have been incurred through March 31, 2017, including $85 million during first-quarter 2017. As a result of regulatory uncertainty, PT-FI has slowed investments in its underground development projects during first-quarter 2017. If PT-FI is unable to reach agreement with the Indonesian government on its long-term mining rights, we intend to significantly reduce or defer investments in underground development projects.

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

b. | Ore milled from the DOZ underground mine is expected to ramp up to 60,000 metric tons of ore per day in 2017.

Indonesia mining’s consolidated sales volumes of 125 million pounds of copper and 177 thousand ounces of gold in first-quarter 2017 were lower than first-quarter 2016 sales of 174 million pounds of copper and 195 thousand ounces of gold, primarily reflecting the impact of regulatory restrictions on PT-FI's concentrate exports beginning on January 12, 2017, and a six-week temporary shutdown at PT Smelting, which began on January 19, 2017.
On April 21, 2017, the Indonesian government issued a permit to PT-FI to enable exports to resume through October 10, 2017, and PT-FI began loading export shipments. PT-FI plans to ramp up its production to full rates during second-quarter 2017. Assuming normal operating rates for the remainder of the year, consolidated sales volumes from Indonesia mining operations are expected to approximate 1.1 billion pounds of copper and 1.9 million ounces of gold for the year 2017, compared with 1.1 billion pounds of copper and 1.1 million ounces of gold for the year 2016. At the Grasberg mine, the sequencing of mining areas with varying ore grades causes fluctuations in quarterly and annual production of copper and gold.
Since mid-April 2017, PT-FI has experienced a high level of worker absenteeism, which has unfavorably impacted mining and milling rates. Union leaders have notified PT-FI of a potential strike during the month of May. PT-FI is working with union leaders, with the support of Indonesian government officials, to encourage a safe and efficient return to normal operations for the benefit of all stakeholders.
Indonesia mining’s projected sales volumes are dependent on a number of factors, including operational performance, workforce productivity, the timing of shipments and its ability to export copper concentrate.

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.

a. | Includes $21 million ($0.17 per pound of copper) of costs charged directly to cost of sales as a result of the impact of regulatory restrictions on PT-FI’s concentrate exports.

A significant portion of PT-FI’s costs are fixed and unit costs vary depending on production volumes and other factors. Indonesia’s unit net cash costs (including gold and silver credits) of $0.82 per pound of copper in first-quarter 2017 were lower than unit net cash costs of $1.24 per pound in first-quarter 2016, primarily reflecting higher gold and silver credits and lower production costs.
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.
As further discussed above in “Regulatory Matters,” PT-FI is continuing to pay a 5.0 percent export duty. Export duties totaled $14 million in first-quarter 2017 and $13 million in first-quarter 2016.
Because certain assets are depreciated on a straight-line basis, PT-FI’s unit depreciation rate varies with the level of copper production and sales.
Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to “Consolidated Results – Revenues” for further discussion of adjustments to prior period provisionally priced copper sales.

PT Smelting intercompany profit represents the change in the deferral of 25 percent of PT-FI’s profit on sales to PT Smelting. Refer to “Operations – Smelting & Refining” for further discussion.
Assuming an average gold price of $1,250 per ounce for the remainder of 2017 and achievement of current sales volume and cost estimates, unit net cash credits (net of gold and silver credits) for Indonesia mining are expected to approximate $0.10 per pound of copper for the year 2017. Indonesia mining’s unit net cash credits for the year 2017 would change by approximately $0.07 per pound for each $50 per ounce change in the average price of gold for the remainder of 2017. Because of the fixed nature of a large portion of Indonesia’s costs, unit costs vary from quarter to quarter depending on copper and gold volumes.
Molybdenum Mines
We have two wholly owned molybdenum mines in North America – the Henderson underground mine and the Climax open-pit mine, both in Colorado. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of the molybdenum concentrate produced at the Henderson and Climax mines, as well as from our North America and South America copper mines, is processed at our own conversion facilities.
Operating and Development Activities. In response to market conditions, the Henderson molybdenum mine continues to operate at reduced rates. Production from the Molybdenum mines totaled 8 million pounds of molybdenum in first-quarter 2017 and 7 million pounds in first-quarter 2016. Refer to “Consolidated Results” for our consolidated molybdenum operating data, which includes sales of molybdenum produced at our Molybdenum mines, and from our North America and South America copper mines, and refer to “Outlook” for projected consolidated molybdenum sales volumes.

Unit net cash costs per pound of molybdenum is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.
Average unit net cash costs for our Molybdenum mines of $7.10 per pound of molybdenum in first-quarter 2017 were lower than $7.43 per pound in first-quarter 2016, primarily reflecting higher volumes. Assuming achievement of current sales volume and cost estimates, we estimate unit net cash costs for the Molybdenum mines are expected to average $7.85 per pound of molybdenum for the year 2017. Refer to “Product Revenues and Production Costs” for a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in our consolidated financial statements.
Smelting and Refining
We wholly own and operate a smelter in Arizona (Miami smelter) and a smelter and refinery in Spain (Atlantic Copper). Additionally, PT-FI owns 25 percent of a smelter and refinery in Gresik, Indonesia (PT Smelting). Treatment charges for smelting and refining copper concentrate consist of a base rate per pound of copper and per ounce of gold and are generally fixed. Treatment charges represent a cost to our mining operations and income to Atlantic Copper and PT Smelting. Thus, higher treatment charges benefit our smelter operations and adversely affect our mining operations. Our North America copper mines are less significantly affected by changes in treatment charges because these operations are largely integrated with our Miami smelter. Through this form of downstream integration, we are assured placement of a significant portion of our concentrate production.
Atlantic Copper smelts and refines copper concentrate and markets refined copper and precious metals in slimes. During first-quarter 2017, Atlantic Copper’s concentrate purchases from our copper mining operations included 21 percent from South America mining and less than 1 percent from our North America copper mines, with the remainder purchased from third parties.
In March 2017, PT Smelting’s anode slimes export license was renewed through March 1, 2018. PT-FI’s contract with PT Smelting provides for PT-FI to supply 100 percent of the copper concentrate requirements (subject to a minimum or maximum rate) necessary for PT Smelting to produce 205,000 metric tons of copper annually on a priority basis. PT-FI may also sell copper concentrate to PT Smelting at market rates for quantities in excess of
46

Table of Contents
205,000 metric tons of copper annually. During first-quarter 2017, PT-FI supplied approximately 80 percent of PT Smelting’s concentrate requirements. An extension of the minimum and maximum treatment charge rates was finalized in April 2017, and is pending approval by the Indonesian government.
We defer recognizing profits on sales from our mining operations to Atlantic Copper and on 25 percent of PT-FI’s sales to PT Smelting until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net additions to net income attributable to common stock of $27 million for first-quarter 2017 and $2 million for first-quarter 2016. Our net deferred profits on our inventories at Atlantic Copper and PT Smelting to be recognized in future periods’ net income attributable to common stock from continuing operations totaled $16 million at March 31, 2017. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in our net deferred profits and quarterly earnings. In second-quarter 2017, we expect increased sales volumes to Atlantic Copper and PT Smelting, resulting in the deferral of approximately $50 million of profit on intercompany sales until final sales to third parties occur.
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. During 2016, we took actions to restore our balance sheet strength through a combination of asset sale transactions, cash flow from operations and capital market transactions. We believe that we have a high-quality portfolio of long-lived copper assets positioned to generate long-term value. In addition to debt reduction plans, we are pursuing opportunities to enhance our mines’ net present values, and we continue to advance studies for future development of our copper resources, the timing of which will be dependent on market conditions.
Cash
Following is a summary of the U.S. and international components of consolidated cash and cash equivalents available to the parent company at March 31, 2017, net of noncontrolling interests’ share, taxes and other costs (in billions):

Cash at domestic companies | $ | 3.4 |
Cash at international operations | 0.6 |
Total consolidated cash and cash equivalents | 4.0 |
Noncontrolling interests’ share | (0.2 | )
Cash, net of noncontrolling interests’ share | 3.8 |
Withholding taxes and other | (0.1 | )
Net cash available | $ | 3.7 |

Cash held at our international operations is generally used to support our foreign operations’ capital expenditures, operating expenses, working capital and other tax payments, or other cash needs. Management believes that
sufficient liquidity is available in the U.S. from cash balances and availability from our revolving credit facility and uncommitted lines of credit. We have not elected to permanently reinvest earnings from our foreign subsidiaries, and we have recorded deferred tax liabilities for foreign earnings that are available to be repatriated to the U.S. From time to time, our foreign subsidiaries distribute earnings to the U.S. through dividends that are subject to applicable withholding taxes and noncontrolling interests’ share.
Debt
Following is a summary of our total debt and the related weighted-average interest rates at March 31, 2017 (in billions, except percentages):

|  |  | Weighted-
|  |  | Average
|  |  | Interest Rate
Senior Notes | $ | 13.9 |  |  | 4.4%
Cerro Verde Credit Facility | 1.3 |  |  | 2.9%
Other FCX debt | 0.2 |  |  | 2.9%
Total debt | $ | 15.4 |  |  | 4.3%

Table of Contents
At March 31, 2017, we had no borrowings, $39 million in letters of credit issued and availability of $3.5 billion under our revolving credit facility.
Operating Activities
We generated consolidated operating cash flows of $792 million (including $178 million in working capital sources and changes in other tax payments) in first-quarter 2017 and $740 million (including $188 million for working capital sources and changes in other tax payments) in first-quarter 2016.
Subject to future commodity prices for copper, gold and molybdenum, we expect estimated consolidated operating cash flows for the year 2017, plus available cash and availability under our credit facility and uncommitted lines of credit, to be sufficient to fund our budgeted capital expenditures, scheduled debt maturities, noncontrolling interest distributions and other cash requirements for the year. Refer to “Outlook” for further discussion of projected operating cash flows for the year 2017, and to “Risk Factors,” contained in Part I, Item 1A. of our annual report on Form 10-K for the year ended December 31, 2016, for discussion of regulatory matters in Indonesia, which could have a significant impact on future results.
Investing Activities
Capital Expenditures. Capital expenditures, including capitalized interest, totaled $344 million in first-quarter 2017, including $210 million for major mining projects. Capital expenditures, including capitalized interest, totaled $1.0 billion in first-quarter 2016, consisting of $459 million for mining operations (including $350 million for major projects) and $523 million for oil and gas operations.
Lower capital expenditures in first-quarter 2017, compared with first-quarter 2016, primarily reflect a decrease in oil and gas activities as a result of the disposal of significant oil and gas assets in 2016 and a decrease in major mining projects associated with the completion of the Cerro Verde expansion. Refer to “Outlook” for further discussion of projected capital expenditures for the year 2017.
Financing Activities
Debt Transactions. Net repayments of debt in first-quarter 2017 totaled $658 million primarily for the repayment of our 2.15% Senior Notes and payments on the Cerro Verde credit facility.
During first-quarter 2016, net proceeds from debt totaled $354 million primarily reflecting borrowings under our revolving credit facility.
Dividends. The Board suspended our annual common stock dividend in December 2015. The declaration of dividends is at the discretion of our Board and will depend upon our financial results, cash requirements, future prospects and other factors deemed relevant by our Board. Common stock dividends of $1 million in first-quarter 2017 and $4 million in first-quarter 2016 related to accumulated dividends paid for vested stock-based compensation.
Cash dividends paid to noncontrolling interests totaled $15 million in first-quarter 2017 and $18 million in first-quarter 2016. These payments will vary based on the operating results and cash requirements of our consolidated subsidiaries.
CONTRACTUAL OBLIGATIONS
There have been no material changes in our contractual obligations since December 31, 2016. Refer to Part II, Items 7. and 7A. in our annual report on Form 10-K for the year ended December 31, 2016, for information regarding our contractual obligations.
CONTINGENCIES
Environmental and Asset Retirement Obligations

PRODUCT REVENUES AND PRODUCTION COSTS
Mining Product Revenues and Unit Net Cash Cost
Unit net cash costs per pound of copper and molybdenum are measures intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for the respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measures may not be comparable to similarly titled measures reported by other companies.
We present gross profit per pound of copper in the following tables using both a “by-product” method and a “co-product” method. We use the by-product method in our presentation of gross profit per pound of copper because (i) the majority of our revenues are copper revenues, (ii) we mine ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of our costs to revenues from the copper, gold, molybdenum and other metals we produce and (iv) it is the method used by our management and our Board to monitor our mining operations and to compare mining operations in certain industry publications. In the co-product method presentations below, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent our metals sales volumes and realized prices change.
We show revenue adjustments for prior period open sales as a separate line item. Because these adjustments do not result from current period sales, these amounts have been reflected separately from revenues on current period
sales. Noncash and other costs, which are removed from site production and delivery costs in the calculation of unit
net cash costs, consist of items such as stock-based compensation costs, start-up costs, inventory adjustments,
long-lived asset impairments, restructuring and/or unusual charges. As discussed above, gold, molybdenum and
other metal revenues at copper mines are reflected as credits against site production and delivery costs in the by-product method. The following schedules are presentations under both the by-product and co-product methods
together with reconciliations to amounts reported in our consolidated financial statements.

CAUTIONARY STATEMENT
Our discussion and analysis contains forward-looking statements in which we discuss our potential future performance. Forward-looking statements are all statements other than statements of historical facts, such as projections or expectations relating to ore grades and milling rates, production and sales volumes, unit net cash costs, operating cash flows, capital expenditures, exploration efforts and results, development and production activities and costs, liquidity, tax rates, the impact of copper, gold and molybdenum price changes, the impact of deferred intercompany profits on earnings, reserve estimates, future dividend payments, and share purchases and sales. The words “anticipates,” “may,” “can,” “plans,” “believes,” “estimates,” “expects,” “projects,” “targets,” “intends,” “likely,” “will,” “should,” “to be,” “potential” and any similar expressions are intended to identify those assertions as forward-looking statements.
We caution readers that forward-looking statements are not guarantees of future performance and actual results may differ materially from those anticipated, projected or assumed in the forward-looking statements. Important factors that can cause our actual results to differ materially from those anticipated in the forward-looking statements include supply of and demand for, and prices of, copper, gold and molybdenum; mine sequencing; production rates; potential effects of cost and capital expenditure reductions, and production curtailments on financial results and cash flow; potential inventory adjustments; potential impairment of long-lived mining assets; the outcome of negotiations with the Indonesian government regarding PT-FI’s COW; the potential effects of violence in Indonesia generally and in the province of Papua; industry risks; regulatory changes; political risks; labor relations; weather- and climate-related risks; environmental risks; litigation results (including the final disposition of the recent unfavorable Indonesian Tax Court ruling relating to surface water taxes); and other factors described in more detail in Part I, Item 1A. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2016, filed with the SEC. With respect to our operations in Indonesia, such factors include whether PT-FI will be able to resolve complex regulatory matters in Indonesia.
Investors are cautioned that many of the assumptions upon which our forward-looking statements are based are likely to change after the forward-looking statements are made, including for example commodity prices, which we cannot control, and production volumes and costs, some aspects of which we may not be able to control. Further, we may make changes to our business plans that could affect our results. We caution investors that we do not intend to update forward-looking statements more frequently than quarterly notwithstanding any changes in our assumptions, changes in business plans, actual experience or other changes, and we undertake no obligation to update any forward-looking statements.

Item 3. | Quantitative and Qualitative Disclosures About Market Risk.

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

Item 4. | Controls and Procedures.

(a) | Evaluation of disclosure controls and procedures. Our chief executive officer and chief financial officer, with the participation of management, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this quarterly report on Form 10-Q. Based on their evaluation, they have concluded that our disclosure controls and procedures are effective as of March 31, 2017.

(b) | Changes in internal control over financial reporting. There has been no change in our internal control over financial reporting that occurred during the quarter ended March 31, 2017, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. | OTHER INFORMATION

Item 1. | Legal Proceedings.

We are involved in numerous legal proceedings that arise in the ordinary course of our business or that are associated with environmental issues arising from legacy operations conducted over the years by Freeport Minerals Corporation and its affiliates. We are also involved from time to time in other reviews, investigations and proceedings by government agencies, some of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief.
Management does not believe, based on currently available information, that the outcome of any proceeding reported in Note 9 of this quarterly report on Form 10-Q for the period ended March 31, 2017, and in Part I, Item 3. “Legal Proceedings” and Note 12 of our annual report on Form 10-K for the year ended December 31, 2016, will have a material adverse effect on our financial condition; although individual outcomes could be material to our operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period.
Item 1A. Risk Factors.
The risk factor “Mine closure and reclamation regulations impose substantial costs on our operations and include requirements that we provide financial assurance supporting those obligations. We also have plugging and abandonment obligations related to our remaining oil and gas properties, and are required to provide bonds or other forms of financial assurance in connection with those operations. Changes in or the failure to comply with these requirements could have a material adverse effect on us” which was included in our annual report on Form 10-K for the year ended December 31, 2016, is updated to add the following:
The United States (U.S.) Environmental Protection Agency extended the comment period for the proposed regulations under Section 108(b) of CERCLA to July 11, 2017. Since filing our annual report on Form 10-K in February 2017, we have evaluated the potential impact of these proposed rules. Based on this evaluation, we believe that, if adopted without material modification, the rules would impose financial responsibility obligations on U.S. hard rock mining operations that are unnecessary, duplicative of existing state and other federal requirements, and unreasonable. Our initial calculations also suggest that the financial responsibility amounts would be difficult, if not impossible, for us and others to meet with corporate resources, and would be extremely expensive, if not impossible, to finance with third-party financial instruments such as letters of credit, bonds or insurance. We and others in the industry will participate in the public comment process and oppose the adoption of these rules in anything like their proposed form, as adoption in that form would severely harm the international competitiveness of the U.S. hard rock mining

industry and would materially and adversely affect our cash flows, results of operations and financial condition.
Except as described above, there have been no material changes to our risk factors during the three-month period ending March 31, 2017. For additional information on risk factors, refer to Part I, Item 1A. “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2016.

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

There were no unregistered sales of equity securities during the three months ended March 31, 2017.
There were no shares of common stock purchased by us during the three months ended March 31, 2017. On July 21, 2008, our Board of Directors approved an increase in our open-market share purchase program for up to 30 million shares. There have been no purchases under this program since 2008. This program does not have an expiration date. At March 31, 2017, there were 23.4 million shares that could still be purchased under the program.

Item 4. | Mine Safety Disclosures.

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