Consolidated Sales Volumes
First-quarter 2018 copper sales of 993 million pounds approximated the January 2018 estimate of 1.0 billion pounds, and were higher than first-quarter 2017 sales of 809 million pounds, primarily reflecting higher operating rates in Indonesia.
First-quarter 2018 gold sales of 610 thousand ounces were lower than the January 2018 estimate of 675 thousand ounces, primarily because of lower-than-expected mill throughput rates associated with maintenance activities at Grasberg. First-quarter 2018 gold sales were higher than first-quarter 2017 sales of 182 thousand ounces, primarily reflecting higher ore grades and operating rates in Indonesia.
Lower operating rates in first-quarter 2017 reflected the regulatory restrictions on PT-FI's concentrate exports from mid-January 2017 to mid-April 2017.
First-quarter 2018 molybdenum sales of 24 million pounds approximated the January 2018 estimate and first-quarter 2017 sales of 24 million pounds.
Sales volumes for the year 2018 are expected to approximate 3.8 billion pounds of copper, 2.4 million ounces of gold and 95 million pounds of molybdenum, including 970 million pounds of copper, 700 thousand ounces of gold and 24 million pounds of molybdenum in second-quarter 2018.
Projections for 2018 and other forward looking statements in this release assume resolution of PT-FI’s long-term mining rights or an extension of PT-FI’s temporary IUPK after June 30, 2018.
Consolidated Unit Costs
Consolidated average unit net cash costs (net of by-product credits) for FCX's copper mines of $0.98 per pound of copper in first-quarter 2018 were lower than unit net cash costs of $1.39 per pound in first-quarter 2017, primarily reflecting higher sales volumes and by-product credits.

Freeport-McMoRan |  | 3

Assuming average prices of $1,300 per ounce of gold and $12.00 per pound of molybdenum for the remainder of 2018 and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for copper mines are expected to average $1.01 per pound of copper for the year 2018. The impact of price changes on consolidated unit net cash costs would approximate $0.025 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 for the remainder of 2018. Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices, primarily for gold and molybdenum.
MINING OPERATIONS
North America Copper Mines. FCX operates seven open-pit copper mines in North America - Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. In addition to copper, certain of FCX's North America copper mines produce molybdenum concentrate, gold and silver.
All of the North America mining operations are wholly owned, except for Morenci. FCX records its 72 percent undivided joint venture interest in Morenci using the proportionate consolidation method.
Operating and Development Activities. FCX has significant undeveloped reserves and resources in North America and a portfolio of potential long-term development projects. Future investments will be undertaken based on the results of economic and technical feasibility studies, and are dependent on market conditions. FCX continues to study opportunities to reduce the capital intensity of its potential long-term development projects.
Through exploration drilling, FCX has identified a significant resource at its wholly owned Lone Star project located near the Safford operation in eastern Arizona. FCX has commenced an initial project to develop the Lone Star oxide ores with first production expected by the end of 2020. Total estimated capital costs, including mine equipment and pre-production stripping, approximate $850 million and will benefit from the utilization of existing infrastructure at the adjacent Safford operation. At March 31, 2018, approximately $35 million has been incurred for this project. Production from the Lone Star oxide ores is expected to average approximately 200 million pounds of copper per year with an approximate 20-year mine life. The project also advances the potential for development of a larger-scale district opportunity. FCX is conducting additional drilling to follow up on positive exploration results as it continues to evaluate longer term opportunities available from the significant long-term sulfide potential in the Lone Star/Safford minerals district.
Operating Data. Following is summary consolidated operating data for the North America copper mines for the three months ended March 31, 2018 and 2017:

North America's consolidated copper sales volumes of 384 million pounds in first-quarter 2018 were higher than first-quarter 2017 sales of 375 million pounds, primarily reflecting timing of shipments. North America copper sales are estimated to approximate 1.5 billion pounds for the year 2018, compared with 1.5 billion pounds in 2017.
Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.74 per pound of copper in first-quarter 2018 were higher than unit net cash costs of $1.46 per pound in first-quarter 2017, primarily reflecting higher repair and maintenance costs.
Average unit net cash costs (net of by-product credits) for the North America copper mines are expected to approximate $1.71 per pound of copper for the year 2018, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $12.00 per pound for the remainder of 2018. North America's average unit net cash costs for the year 2018 would change by approximately $0.03 per pound for each $2 per pound change in the average price of molybdenum for the remainder of 2018.
South America Mining. FCX operates two copper mines in South America - Cerro Verde in Peru (in which FCX owns a 53.56 percent interest) and El Abra in Chile (in which FCX owns a 51 percent interest). These operations are consolidated in FCX's financial statements. In addition to copper, the Cerro Verde mine produces molybdenum concentrate and silver.
Operating and Development Activities. The Cerro Verde expansion project, which commenced operations in September 2015, achieved capacity operating rates in early 2016. The project expanded the concentrator facilities' capacity from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day. Cerro Verde's expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. The project has continued to perform well, with average mill throughput rates of 385,500 metric tons of ore per day in first-quarter 2018, including a daily record of 462,900 metric tons of ore.
Exploration results at El Abra indicate a significant sulfide resource, which could potentially support a major mill project similar to facilities recently constructed at Cerro Verde. FCX continues to evaluate a major expansion at El Abra to process additional sulfide material and to achieve higher recoveries. Future investments will depend on technical studies, which are being advanced, economic factors and market conditions.
Operating Data. Following is summary consolidated operating data for the South America mining operations for the three months ended March 31, 2018 and 2017:

South America's consolidated copper sales volumes of 290 million pounds in first-quarter 2018 were lower than first-quarter 2017 sales of 309 million pounds, primarily reflecting lower ore grades and recovery rates at Cerro Verde. Sales from South America mining are expected to approximate 1.2 billion pounds of copper for the year 2018, compared with 1.2 billion pounds of copper in 2017.
Average unit net cash costs (net of by-product credits) for South America mining of $1.74 per pound of copper in first-quarter 2018 were higher than unit net cash costs of $1.53 per pound in first-quarter 2017, primarily reflecting higher mining rates and lower ore grades. Average unit net cash costs (net of by-product credits) for South America mining are expected to approximate $1.64 per pound of copper for the year 2018, based on current sales volume and cost estimates and assuming an average price of $12.00 per pound of molybdenum for the remainder of 2018.
Indonesia Mining. Through its 90.64 percent owned and consolidated subsidiary PT Freeport Indonesia (PT-FI), FCX's assets include one of the world's largest copper and gold deposits at the Grasberg minerals district in Papua, Indonesia. PT-FI operates a proportionately consolidated joint venture, which produces copper concentrate that contains significant quantities of gold and silver.
Regulatory Matters. PT-FI continues to actively engage with Indonesian government officials to address regulatory changes that conflict with its contractual rights in a manner that provides long-term stability for PT-FI’s operations and investment plans, and protects value for FCX’s shareholders.
Following a framework understanding reached in August 2017, the parties have been engaged in negotiation and documentation of a special license (IUPK) and accompanying documentation for assurances on legal and fiscal terms to provide PT-FI with long-term mining rights through 2041. In addition, the IUPK would provide that PT-FI construct a smelter within five years of reaching a definitive agreement and include agreement for the divestment of 51 percent of the project area interests to Indonesian participants at fair market value.
In late 2017, the Indonesian government (including the regional government of Papua Province and Mimika Regency) and PT Indonesia Asahan Aluminium (Inalum), a state-owned enterprise, which leads the Indoneisan government's consortium of investors, formed a special purpose company to acquire Grasberg project area interests. Inalum is owned 100 percent by the Indonesian government and currently holds 9.36 percent of PT-FI's outstanding common stock.
FCX continues to engage with Inalum and PT-FI’s joint venture partner on potential arrangements that would result in the Inalum consortium acquiring interests that would meet the Indonesian government’s 51 percent ownership objective in a manner satisfactory to all parties, and in a structure that would provide for continuity of FCX’s management of PT-FI’s operations and governance of the business. The parties continue to negotiate documentation on a comprehensive agreement for PT-FI’s extended operations and to reach agreement on timing, process and governance matters relating to the divestment. The parties have a mutual objective of completing negotiations and the required documentation as soon as possible.
PT-FI is also engaged in discussions with Indonesia's Ministry of Environment and Forestry regarding approval of pending environmental permits and April 2018 ministerial actions imposing new environmental standards, which are subject to a six-month transition period and conflict with PT-FI's approved environmental management programs. Resolution of these matters is a requirement for concluding a comprehensive agreement for PT-FI's extended operations.
In December 2017, the Indonesian government extended PT-FI’s temporary IUPK to June 30, 2018, to enable normal operations to continue during the negotiation period. In February 2018, PT-FI's export license was extended to February 15, 2019. Until a definitive agreement is reached, PT-FI has reserved all rights under its Contract of Work (COW), including dispute resolution procedures.

Freeport-McMoRan |  | 6

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 until transitioning to the Grasberg Block Cave underground mine in the first half of 2019.
PT-FI has several projects in the Grasberg minerals district related to the development of its large-scale, long-lived, high-grade underground ore bodies. In aggregate, these underground ore bodies are expected to produce large-scale quantities of copper and gold following the transition from the Grasberg open pit. Substantial progress has been made to prepare for the transition to mining of the Grasberg Block Cave underground mine. Mine development activities are sufficiently advanced to commence caving by early 2019. The ore flow system and underground rail line are expected to be installed during 2018.
PT-FI continues to review its mine plan for the Deep Mill Level Zone underground mine, which is currently in pre-commercial production. In response to recent mining-induced seismic activity, the development plans have been revised to a slower start-up to full production to manage rock stress encountered in the early phase of cave development.
Subject to reaching a definitive agreement with the Indonesian government to support PT-FI's long-term investment plans, estimated annual capital spending on these projects would average $0.8 billion per year ($0.7 billion per year net to PT-FI) over the next five years. Considering the long-term nature and size of these projects, actual costs could vary from these estimates. 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 a definitive agreement with the Indonesian government on its long-term mining rights, FCX intends to reduce or defer investments significantly in its underground development projects and will pursue dispute resolution procedures under its COW.

Freeport-McMoRan |  | 7

Indonesia's consolidated sales of 319 million pounds of copper and 603 thousand ounces of gold in first-quarter 2018 were higher than first-quarter 2017 sales of 125 million pounds of copper and 177 thousand ounces of gold, primarily reflecting higher operating rates and gold ore grades. Lower operating rates in first-quarter 2017 reflected the regulatory restrictions on PT-FI's concentrate exports from mid-January 2017 to mid-April 2017.
During first-quarter 2018, Indonesia mining's copper and gold production was adversely affected by lower- than-expected mill throughput rates associated with maintenance activities on PT-FI's ore-flow systems and the characteristics of ore processed during the quarter. Corrective actions are being taken to restore reliability and productivity.
Assuming achievement of planned operating rates for the remainder of 2018, consolidated sales volumes from Indonesia mining are expected to approximate 1.15 billion pounds of copper and 2.4 million ounces of gold for the year 2018, compared with 1.0 billion pounds of copper and 1.5 million ounces of gold for the year 2017.
A significant portion of PT-FI's costs are fixed and unit costs vary depending on production volumes and other factors. As a result of higher sales volumes and gold and silver credits, Indonesia had unit net cash credits (including gold and silver credits) of $0.63 per pound of copper in first-quarter 2018, compared with unit net cash costs of $0.80 per pound in first-quarter 2017.
Assuming an average gold price of $1,300 per ounce for the remainder of 2018 and achievement of current sales volume and cost estimates, unit net cash credits (including gold and silver credits) for Indonesia mining are expected to approximate $0.55 per pound of copper for the year 2018. Indonesia mining's unit net cash credits for the year 2018 would change by approximately $0.09 per pound for each $50 per ounce change in the average price of gold for the remainder of 2018. Because of the fixed nature of a large portion of Indonesia's costs, unit net cash credits/costs vary from quarter to quarter depending on copper and gold volumes.
Indonesia mining's projected sales volumes and unit net cash credits for the year 2018 are dependent on a number of factors, including operational performance, workforce productivity, timing of shipments, and Indonesia regulatory matters, including the resolution of PT-FI's long-term mining rights or an extension of PT-FI's temporary IUPK after June 30, 2018.
Molybdenum Mines. FCX has two wholly owned molybdenum mines - the Henderson underground mine and the Climax open-pit mine - both in Colorado. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of molybdenum concentrate produced at the Henderson and Climax mines, as well as from FCX's North America and South America copper mines, is processed at FCX's conversion facilities.
Operating and Development Activities. Production from the Molybdenum mines totaled 9 million pounds of molybdenum in first-quarter 2018 and 8 million pounds in first-quarter 2017. Refer to summary operating data on page 3 for FCX's consolidated molybdenum sales and average realized prices, which includes sales of molybdenum produced at the Molybdenum mines, and from FCX's North America and South America copper mines.
Unit net cash costs for the Molybdenum mines averaged $8.57 per pound of molybdenum in first-quarter 2018 and $7.02 per pound in first-quarter 2017. Based on current sales volume and cost estimates, average unit net cash costs for the Molybdenum mines are expected to approximate $8.75 per pound of molybdenum for the year 2018.
For a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in FCX's consolidated financial statements, refer to the supplemental schedules, "Product Revenues and Production Costs," beginning on page X, which are available on FCX's website, "fcx.com."
Mining Exploration Activities. FCX's mining exploration activities are generally associated with its existing mines, focusing on opportunities to expand reserves and resources to support development of additional future production capacity. A drilling program to further delineate the Lone Star resource continues to indicate additional mineralization in this district. Exploration results continue to indicate opportunities for significant future potential reserve additions in North America and South America. Exploration spending is expected to approximate $72 million for the year 2018, consistent with the year 2017.

CASH FLOWS, CASH and DEBT
Operating Cash Flows. FCX generated operating cash flows of $1.4 billion (net of $21 million in working capital uses and timing of other tax payments) in first-quarter 2018.
Based on current sales volume and cost estimates, and assuming average prices of $3.15 per pound of copper, $1,300 per ounce of gold and $12.00 per pound of molybdenum for the remainder of 2018, FCX's consolidated operating cash flows are estimated to approximate $5.6 billion for the year 2018 (including $0.2 billion in working capital sources and timing of other tax payments). The impact of price changes during the remainder of 2018 on operating cash flows would approximate $250 million for each $0.10 per pound change in the average price of copper, $90 million for each $50 per ounce change in the average price of gold and $85 million for each $2 per pound change in the average price of molybdenum.
Capital Expenditures. Capital expenditures totaled $402 million for first-quarter 2018 (including approximately $250 million for major mining projects). Capital expenditures are expected to approximate $2.0 billion for the year 2018, including $1.1 billion for major mining projects primarily associated with underground development activities in the Grasberg minerals district and development of the Lone Star oxide project.
If PT-FI is unable to reach a definitive agreement with the Indonesian government on its long-term mining rights, FCX intends to reduce or defer investments significantly in its underground development projects and will pursue dispute resolution procedures under its COW.
Cash. Following is a summary of the U.S. and international components of consolidated cash and cash equivalents available to the parent company, net of noncontrolling interests' share, taxes and other costs at March 31, 2018 (in billions):

Cash at domestic companies | $ | 2.5 |  |
Cash at international operations | 1.2 |  |
Total consolidated cash and cash equivalents | 3.7 |  |
Noncontrolling interests' share | (0.4 | ) |
Cash, net of noncontrolling interests' share | 3.3 |  |
Withholding taxes and other | (0.1 | ) |
Net cash available | $ | 3.2 |  |

Debt. Following is a summary of total debt and the related weighted-average interest rates at March 31, 2018 (in billions, except percentages):

|  |  | Weighted- |
|  |  | Average |
|  |  | Interest Rate |
Senior Notes | $ | 10.4 |  |  | 4.7% |
Cerro Verde credit facility | 1.2 |  |  | 3.8% |
Total debt | $ | 11.6 |  |  | 4.6% |

During first-quarter 2018, FCX repaid borrowings totaling $1.5 billion, consisting of $1.4 billion for senior notes due March 2018 and $0.1 billion for the Cerro Verde credit facility.
In April 2018, FCX redeemed $404 million of senior notes due 2022 and $50 million of senior notes due 2023. FCX expects to record a gain of $10 million in second-quarter 2018 related to these redemptions, and the aggregate annual cash interest savings approximate $30 million.
At March 31, 2018, FCX had no borrowings, $13 million in letters of credit issued and $3.5 billion available under its revolving credit facility. During April 2018, FCX entered into a new $3.5 billion, five-year revolving credit facility with substantially similar structure and terms as its prior facility, which was scheduled to mature in May 2019.

Additional information about FCX is available on FCX's website at "fcx.com."
Cautionary Statement and Regulation G Disclosure: This press release contains forward-looking statements in which FCX discusses its 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. The declaration of dividends is at the discretion of the Board and will depend on FCX's financial results, cash requirements, future prospects, and other factors deemed relevant by the Board.
FCX cautions 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 FCX's 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 inventory adjustments; potential impairment of long-lived mining assets; the outcome of negotiations with the Indonesian government regarding PT-FI's long-term mining rights; 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 (including resolution of the administrative sanctions and other environmental matters pending before Indonesia's Ministry of Environment and Forestry); litigation results (including the final disposition of Indonesian tax disputes and the outcome of Cerro Verde's royalty dispute with the Peruvian national tax authority); and other factors described in more detail under the heading “Risk Factors” in FCX's Annual Report on Form 10-K for the year ended December 31, 2017, filed with the U.S. Securities and Exchange Commission (SEC) as updated by FCX's subsequent filings with the SEC. With respect to FCX's operations in Indonesia, such factors include whether PT-FI will be able to resolve complex regulatory matters in Indonesia by June 30, 2018, or obtain an extension of its temporary IUPK after June 30, 2018.
Investors are cautioned that many of the assumptions upon which FCX's forward-looking statements are based are likely to change after the forward-looking statements are made, including for example commodity prices, which FCX cannot control, and production volumes and costs, some aspects of which FCX may not be able to control. Further, FCX may make changes to its business plans that could affect its results. FCX cautions investors that it does not intend to update forward-looking statements more frequently than quarterly notwithstanding any changes in its assumptions, changes in business plans, actual experience or other changes, and FCX undertakes no obligation to update any forward-looking statements.
This press release also contains certain financial measures such as unit net cash (credits) costs per pound of copper and molybdenum and adjusted net income, which are not recognized under U.S. generally accepted accounting principles. As required by SEC Regulation G, reconciliations of these measures to amounts reported in FCX's consolidated financial statements are in the supplemental schedules of this press release, which are also available on FCX's website, "fcx.com."

INCOME TAXES
Following is a summary of the approximate amounts used in the calculation of FCX's consolidated income tax provision for three months ended March 31, 2018 and 2017 (in millions, except percentages):

| Three Months Ended March 31, |

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

b. | In accordance with applicable accounting rules, FCX adjusts its interim provision for income taxes equal to its consolidated tax rate.

c. | The consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which FCX operates. Accordingly, variations in the relative proportions of jurisdictional income result in fluctuations to FCX's consolidated effective income tax rate. Assuming achievement of current sales volume and cost estimates and average prices of $3.15 per pound for copper, $1,300 per ounce for gold and $12.00 per pound for molybdenum for the remainder of 2018, FCX estimates its consolidated effective tax rate for the year 2018 will approximate 36 percent and would decrease with higher prices.

DERIVATIVE INSTRUMENTS
For first-quarter 2018, FCX's mined copper was sold 59 percent in concentrate, 21 percent as cathode and 20 percent as rod from North America operations. Substantially all of FCX's copper concentrate and cathode sales contracts provide final pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted London Metal Exchange (LME) monthly average spot copper prices. FCX records revenues and invoices customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement. During first-quarter 2018, LME spot copper prices averaged $3.16 per pound and closed at $3.03 per pound on March 31, 2018. Because a significant portion of FCX's copper concentrate and cathode sales in any quarterly period usually remain subject to final pricing, the quarter-end forward price is a major determinant of the average recorded copper price for the period. FCX's average realized copper price was $3.11 per pound in first-quarter 2018.
Following is a summary of the adjustments to prior period and current period provisionally priced copper sales (in millions, except per share amounts):

| Three Months Ended March 31,
| 2018 |  | 2017
| Prior Period a |  | Current Period b |  | Total |  | Prior Period a |  | Current Period b |  | Total
Revenues | $ | (78 | ) |  | $ | (57 | ) |  | $ | (135 | ) |  | $ | 91 |  |  | $ | 16 |  |  | $ | 107 |
Net income attributable to common stock | $ | (35 | ) |  | $ | (23 | ) |  | $ | (58 | ) |  | $ | 39 |  |  | $ | 8 |  |  | $ | 47 |
Net income per share of common stock | $ | (0.02 | ) |  | $ | (0.02 | ) |  | $ | (0.04 | ) |  | $ | 0.03 |  |  | $ | — |  |  | $ | 0.03 |

a. | Reflects adjustments to prior period provisionally priced copper sales (i.e., provisionally priced copper sale at December 31, 2017 and 2016).

b. | Reflects adjustments to first-quarter 2018 and first-quarter 2017 provisionally priced copper sales.

At March 31, 2018, FCX had provisionally priced copper sales at its copper mining operations totaling 324 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $3.04 per pound, subject to final pricing over the next several months. FCX estimates that each $0.05 change in the price realized from the March 31, 2018, provisional price recorded would have an approximate $10 million effect on 2018 net income attributable to common stock. The LME spot copper price closed at $3.13 per pound on April 23, 2018.
DEFERRED PROFITS
FCX defers recognizing profits on sales from its mining operations to Atlantic Copper and on 25 percent of PT-FI's sales to PT Smelting (PT-FI's 25 percent-owned Indonesian smelting unit) until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net (reductions) additions to net income attributable to common stock totaling $(7) million for first-quarter 2018 and $27 million for first-quarter 2017. FCX's net deferred profits on its inventories at Atlantic Copper and PT Smelting to be recognized in future periods' net income attributable to common stock totaled $95 million at March 31, 2018. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in FCX's net deferred profits and quarterly earnings.

BUSINESS SEGMENTS
FCX has organized its mining operations into four primary divisions – North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX's reportable segments, which include the Morenci, Cerro Verde and Grasberg (Indonesia Mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining.
Intersegment sales between FCX’s business segments are based on terms similar to arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, the timing of sales to unaffiliated customers and transportation premiums.
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.

PRODUCT REVENUES AND PRODUCTION COSTS
Unit net cash (credits) costs per pound of copper and molybdenum are measures intended to provide investors with information about the cash-generating capacity of FCX's mining operations expressed on a basis relating to the primary metal product for the respective operations. FCX uses this measure for the same purpose and for monitoring operating performance by its mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. These measures are presented by other metals mining companies, although FCX's measures may not be comparable to similarly titled measures reported by other companies.
FCX presents gross profit per pound of copper in the following tables using both a “by-product” method and a “co-product” method. FCX uses the by-product method in its presentation of gross profit per pound of copper because (i) the majority of its revenues are copper revenues, (ii) it mines ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of FCX's costs to revenues from the copper, gold, molybdenum and other metals it produces and (iv) it is the method used by FCX's management and Board to monitor FCX's mining operations and to compare mining operations in certain industry publications. In the co-product method presentations, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent FCX's metals sales volumes and realized prices change.
FCX shows 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 (credits) 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 FCX's consolidated financial statements.
