NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
NOTE 1. GENERAL INFORMATION
Effective July 14, 2014, Freeport-McMoRan Copper & Gold Inc. changed its name to Freeport-McMoRan Inc. (FCX) to simplify the corporate name and better reflect FCX's expanded portfolio of assets. 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 FCX's consolidated financial statements and notes contained in its annual report on Form 10-K for the year ended December 31, 2013. 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 certain adjustments associated with the acquisitions of Plains Exploration & Production Company (PXP) and McMoRan Exploration Co. (MMR), collectively known as FCX Oil & Gas Inc. (FM O&G), all such adjustments are, in the opinion of management, of a normal recurring nature. Operating results for the three-month and six-month periods ended June 30, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
As further discussed in Note 2, FCX completed its acquisitions of PXP on May 31, 2013, and MMR on June 3, 2013. The results included in these financial statements for second-quarter 2013 and the six months ended June 30, 2013, include PXP's results beginning June 1, 2013, and MMR's results beginning June 4, 2013.
NOTE 2. ACQUISITIONS AND DISPOSITIONS
PXP and MMR Acquisitions. The second-quarter 2013 acquisitions of PXP and MMR added a portfolio of oil and gas assets to FCX's global mining business, creating a U.S.-based natural resources company. The acquisitions have been accounted for under the acquisition method, with FCX as the acquirer.
During the second quarter of 2014, FCX finalized the purchase price allocations, which resulted in a net increase of $20 million to oil and gas properties, an increase of $22 million to goodwill and a net decrease of $42 million to deferred income tax assets.
For further discussion of the PXP and MMR acquisitions and the related financing, refer to Notes 2 and 8 in FCX's annual report on Form 10-K for the year ended December 31, 2013.
Unaudited Pro Forma Consolidated Financial Information. The following unaudited pro forma financial information has been prepared to reflect the acquisitions of PXP and MMR. The unaudited pro forma financial information combines the historical statements of income of FCX, PXP and MMR for the three-month and six-month periods ended June 30, 2013, giving effect to the mergers as if they had occurred on January 1, 2012. The historical consolidated financial information has been adjusted to reflect factually supportable items that are directly attributable to the acquisitions.

Table of Contents
The unaudited pro forma consolidated information has been prepared for illustrative purposes only and is not intended to be indicative of the results of operations that actually would have occurred, or the results of operations expected in future periods, had the events reflected herein occurred on the date indicated. The most significant pro forma adjustments to income from continuing operations for the three-month period ended June 30, 2013, were to exclude $506 million of acquisition-related costs, the net tax benefit of $183 million of acquisition-related adjustments and the $128 million gain on the investment in MMR. Additionally, for the six-month period ended June 30, 2013, the pro forma consolidated information excluded a $77 million gain on the sale of MMR oil and gas properties because of the application of the full cost method of accounting.
Eagle Ford Disposition. On June 20, 2014, FCX completed the sale of its Eagle Ford shale assets to a subsidiary of Encana Corporation (Encana) for cash consideration of $3.1 billion, before closing adjustments from the April 1, 2014, effective date through closing. Under full cost accounting rules, the proceeds were recorded as a reduction of capitalized oil and gas properties, with no gain or loss recognition, except for $58 million of deferred tax expense recorded in connection with the allocation of $221 million of goodwill (for which deferred taxes were not previously provided) to the Eagle Ford shale assets. Approximately $1.3 billion of proceeds from this transaction was placed in a like-kind exchange escrow to reinvest into additional oil and gas interests. On June 30, 2014, $919 million from this like-kind exchange escrow was used to fund the Deepwater Gulf of Mexico (GOM) acquisition discussed below. The remaining $414 million of funds in the like-kind exchange escrow may be used to acquire additional interests in the Deepwater GOM on a tax-efficient basis. Additionally, a portion of the proceeds was used to reduce indebtedness.
Deepwater GOM Acquisition. On June 30, 2014, FCX completed the acquisition of interests in the Deepwater GOM from a subsidiary of Apache Corporation, including interests in the Lucius and Heidelberg oil production development projects and several exploration leases, for $919 million. Based on preliminary valuations, and including transaction costs and estimated asset retirement costs, FCX recorded capitalized costs for oil and gas properties subject to amortization of $460 million and costs not subject to amortization of $476 million. The Deepwater GOM acquisition was funded with a portion of the net proceeds from the sale of the Eagle Ford shale assets.
NOTE 3. EARNINGS PER SHARE
FCX’s basic net income per share of common stock was computed by dividing net income attributable to FCX common stockholders by the weighted-average of common stock outstanding during the period. Diluted net income per share of common stock was computed using the most dilutive of (a) the two-class method or (b) the treasury stock method. Under the two-class method, net income is allocated to each class of common stock and participating securities as if all of the earnings for the period had been distributed. FCX’s participating securities consist of vested restricted stock units (RSUs) for which the underlying common shares are not yet issued and entitle holders to non-forfeitable dividends.
The following table sets forth the computation of basic and diluted net income per share (in millions, except per share amounts):

NOTE 6. DEBT AND EQUITY TRANSACTIONS
In June 2014, FCX announced the redemption of $1.7 billion of the aggregate principal amount of outstanding senior notes on July 23, 2014. The redemptions included $263 million for the 6.125% Senior Notes due 2019, $525 million for the 6½% Senior Notes due 2020, $350 million for the 6.75% Senior Notes due 2022 and $525 million for the 6.875% Senior Notes due 2023. At the redemption date, these senior notes had a book value of $1.8 billion, which included fair value adjustments of $167 million. In accordance with the terms of these senior notes, the redemptions were funded with cash contributions to FM O&G by FCX in exchange for additional equity, which is eliminated in the consolidated financial statements. FCX used available cash and borrowed approximately $950 million under its revolving credit facility and uncommitted lines of credit to fund the contributions to FM O&G. Holders of these senior notes received the principal amount together with the redemption premium and accrued and unpaid interest to the redemption date. As a result of these redemptions, FCX will report a gain on early extinguishment of debt of $58 million in third-quarter 2014.
In May 2014, FCX, PT Freeport Indonesia (PT-FI) and Freeport-McMoRan Oil & Gas LLC (FM O&G LLC, a wholly owned subsidiary of FM O&G and the successor entity of PXP) amended the senior unsecured $3.0 billion revolving credit facility to extend the maturity date one year to May 31, 2019, and increase the aggregate principal amount from $3.0 billion to $4.0 billion, with $500 million available to PT-FI. FCX, PT-FI and FM O&G LLC had entered into the $3.0 billion revolving credit facility on May 31, 2013 (upon completion of the acquisition of PXP). At June 30, 2014, there were no borrowings and $46 million of letters of credit issued under the revolving credit facility, resulting in availability of approximately $4.0 billion, of which $1.5 billion could be used for additional letters of credit.
In April 2014, FCX redeemed $210 million of the aggregate principal amount of the outstanding 6.625% Senior Notes due 2021. In accordance with the terms of the senior notes, the redemption was funded with cash contributions to FM O&G by FCX in exchange for additional equity, which is eliminated in the consolidated financial statements. Holders of these senior notes received the principal amount together with the redemption premium and accrued and unpaid interest to the redemption date. As a result of the redemption, FCX recorded a gain on early extinguishment of debt of $6 million in second-quarter 2014.
In March 2014, Sociedad Minera Cerro Verde S.A.A. (Cerro Verde, FCX's mining subsidiary in Peru) entered into a five-year, $1.8 billion senior unsecured credit facility that is nonrecourse to FCX and the other shareholders of Cerro Verde. The credit facility allows for term loan borrowings up to the full amount of the facility, less any amounts issued and outstanding under a $500 million letter of credit sublimit. Interest on amounts drawn under the term loan is based on London Interbank Offered Rate (LIBOR) plus a spread (currently 1.90 percent) based on Cerro Verde’s total net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) ratio as defined in the agreement. Amounts may be drawn or letters of credit may be issued over a two-year period to fund a portion of Cerro Verde’s expansion project and for Cerro Verde's general corporate purposes. The credit facility amortizes in three installments in amounts necessary for the aggregate borrowings and outstanding letters of credit not to exceed 85 percent of the $1.8 billion commitment on September 30, 2017, 70 percent on March 31, 2018, and 35 percent on September 30, 2018, with the remaining balance due on the maturity date of March 10, 2019. At June 30, 2014, there were no borrowings and no letters of credit issued under Cerro Verde’s credit facility.
FCX recorded a loss on early extinguishment of debt of $45 million ($39 million to net income attributable to FCX common stockholders) in first-quarter 2013 for financing costs incurred for the terminated $9.5 billion acquisition bridge loan facility, which was entered into in December 2012 to provide interim financing for FCX's second-quarter 2013 acquisitions of PXP and MMR.
Consolidated interest expense (excluding capitalized interest) totaled $225 million in second-quarter 2014, $167 million in second-quarter 2013, $449 million for the first six months of 2014 and $242 million for the first six months of 2013. Capitalized interest included in property, plant, equipment and mining development costs, net, totaled $39 million in second-quarter 2014, $27 million in second-quarter 2013, $79 million for the first six months of 2014 and $45 million for the six months of 2013. Capitalized interest included in oil and gas properties not subject to amortization totaled $22 million in second-quarter 2014, $8 million in second-quarter 2013, $45 million for the first six months of 2014 and $8 million for the first six months of 2013.
On June 25, 2014, FCX's Board of Directors declared a quarterly dividend of $0.3125 per share, which was paid on August 1, 2014, to common shareholders of record at the close of business on July 15, 2014.
In connection with the second-quarter 2013 acquisition of PXP, FCX issued 91 million shares of its common stock.

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. As a result of the acquisition of PXP, FCX assumed a variety of crude oil and natural gas commodity derivatives to hedge the exposure to the volatility of crude oil and natural gas commodity prices. Derivative financial instruments used by FCX to manage its risks do not contain credit risk-related contingent provisions. As of June 30, 2014, and December 31, 2013, 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), a division of the New York Mercantile Exchange (NYMEX), 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 during the three-month or six-month periods ended June 30, 2014 and 2013, resulting from hedge ineffectiveness. At June 30, 2014, FCX held copper futures and swap contracts that qualified for hedge accounting for 53 million pounds at an average contract price of $3.10 per pound, with maturities through September 2015.
A summary of gains (losses) recognized in revenues for derivative financial instruments related to commodity contracts that are designated and qualify as fair value hedge transactions, along with the unrealized gains (losses) on the related hedged item follows (in millions):

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, 2013, 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 concentrates or cathodes at the then-current LME or COMEX copper price or the London gold price as defined in the contract. Mark-to-market price fluctuations recorded through the settlement date are reflected in revenues for sales contracts and in cost of sales as production and delivery costs for purchase contracts.

Crude Oil and Natural Gas Contracts. As a result of the acquisition of PXP, FCX has derivative contracts for 2014 and 2015 that consist of crude oil options and natural gas swaps. These crude oil and natural gas derivatives are not designated as hedging instruments and are recorded at fair value with the mark-to-market gains and losses recorded in revenues.
The crude oil options were entered into by PXP to protect the realized price of a portion of expected future sales in order to limit the effects of crude oil price decreases. At June 30, 2014, these contracts are composed of crude oil put spreads consisting of put options with a floor limit. The premiums associated with put options are deferred until the settlement period. At June 30, 2014, the deferred option premiums and accrued interest associated with the crude oil option contracts totaled $329 million, which was included as a reduction of the fair value of the crude oil options contracts. At June 30, 2014, the outstanding crude oil option contracts, which settle monthly and cover approximately 20 million barrels in 2014 and approximately 31 million barrels in 2015, follow:

|  |  |  |  |  | Average Strike Price (per barrel)a |  |  |  |
Period |  | Instrument Type |  | Daily Volumes (thousand barrels) |  | Floor |  | Floor Limit |  | Average Deferred Premium (per barrel) |  | Index

Jan - Dec |  | Put options b |  | 84 |  |  | 90 |  |  | 70 |  |  | 6.89 |  |  | Brent

a. | The average strike prices do not reflect any premiums to purchase the put options.

b. | If the index price is less than the per barrel floor, FCX receives the difference between the per barrel floor and the index price up to a maximum of $20 per barrel less the option premium. If the index price is at or above the per barrel floor, FCX pays the option premium and no cash settlement is received.

In addition, at June 30, 2014, outstanding natural gas swaps with a weighted-average fixed swap price of $4.09 per million British thermal units (MMBtu) cover approximately 18 million MMBtu of natural gas, with maturities through December 2014 (on daily volumes of 100,000 MMBtu). If the Henry Hub index price is less than the fixed price, FCX receives the difference between the fixed price and the Henry Hub index price. FCX pays the difference between the index price and the fixed price if the Henry Hub index price is greater than the fixed price.
Copper Forward Contracts. Atlantic Copper, FCX's wholly owned smelting and refining unit in Spain, enters into forward copper 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 June 30, 2014, Atlantic Copper held net forward copper purchase contracts for 19 million pounds at an average contract price of $3.07 per pound, with maturities through July 2014.

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 June 30, 2014, the maximum amount of credit exposure associated with derivative transactions was $62 million.
Other Financial Instruments. Other financial instruments include cash and cash equivalents, accounts receivable, investment securities, legally restricted funds, accounts payable and accrued liabilities, dividends payable and long-term debt. The carrying value for cash and cash equivalents (which included time deposits of $72 million at June 30, 2014, and $211 million at December 31, 2013), accounts receivable, accounts payable and accrued liabilities, and dividends payable approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 8 for the fair values of investment securities, legally restricted funds and long-term debt).
In addition, FCX has non-detachable warrants, which are considered to be embedded derivative instruments, associated with FM O&G's Plains Offshore Operations Inc. (Plains Offshore) 8% Convertible Preferred Stock (Preferred Stock) (refer to Note 8 for the fair value of these instruments).

Table of Contents
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 inputs) and the lowest priority to unobservable inputs (Level 3 inputs). 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 second-quarter 2014.
A summary of the carrying amount and fair value of FCX’s financial instruments, other than cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, and dividends payable (refer to Note 7), follows (in millions):

Valuation Techniques
Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.
Fixed income securities (U.S. core fixed income funds, government securities, corporate bonds, asset-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.
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.
FCX’s embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales have critical inputs of quoted monthly LME or COMEX copper forward prices and the London gold forward price at each reporting date based on the month of maturity; 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 crude oil options are valued using an option pricing model, which uses various inputs including IntercontinentalExchange, Inc. crude oil prices, volatilities, interest rates and contract terms. FCX's derivative financial instruments for natural gas swaps are valued using a pricing model that has various inputs including NYMEX price quotations, interest rates and contract terms. Valuations are adjusted for credit quality, using the counterparties' credit quality for asset balances and FCX's credit quality for liability balances (which considers the impact of netting agreements on counterparty credit risk, including whether the position with the counterparty is a net asset or net liability). For asset balances, FCX uses the credit default swap value for counterparties when available or the spread between the risk-free interest rate and the yield rate on the counterparties' publicly traded debt for similar instruments. The 2014 natural gas swaps are classified within Level 2 of the fair value hierarchy because the inputs used in the valuation models are directly or indirectly observable for substantially the full term of the instruments. The 2014 and 2015 crude oil options are classified within Level 3 of the fair value hierarchy because the inputs used in the valuation models are not observable for substantially the full term of the instruments. The significant unobservable inputs used in the fair value measurement of the crude oil options are implied volatilities and deferred premiums. Significant increases (decreases) in implied volatilities in isolation would result in a significantly higher (lower) fair value measurement. The implied volatilities ranged from 14 percent to 55 percent, with a weighted average of 21 percent. The deferred premiums ranged from $5.15 per barrel to $7.22 per barrel, with a weighted average of $6.49 per barrel. Refer to Note 7 for further discussion of these derivative financial instruments.
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 warrants associated with the Plains Offshore Preferred Stock was determined with an option pricing model that used unobservable inputs. The inputs used in the valuation model are the estimated fair value of the underlying Plains Offshore common stock, expected exercise price, expected term, expected volatility and risk-free interest rate. The assumptions used in the valuation model are highly subjective because the common stock of Plains Offshore is not publicly traded. As a result, these warrants are classified within Level 3 of the fair value hierarchy.
Long-term debt, including the current portion, is not actively traded and is valued using prices obtained from a readily available pricing source 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 June 30, 2014.
A summary of the changes in the fair value of FCX's Level 3 instruments follows (in millions):

| Crude Oil |  | Plains Offshore |
| Options |  | Warrants |

NOTE 9. CONTINGENCIES AND COMMITMENTS
Litigation. During second-quarter 2014, 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, 2013, and Note 9 of FCX's quarterly report on Form 10-Q for the quarter ended March 31, 2014.
Tax and Other Matters. Cerro Verde Royalty Dispute. There were no significant changes to the Cerro Verde royalty dispute during the first six months of 2014 (refer to Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2013, for further discussion of this matter).
Indonesia Tax Matters. As reported in Note 12 of FCX’s annual report on Form 10-K for the year ended December 31, 2013, PT-FI has received assessments from the Indonesian tax authorities for additional taxes and interest related to various audit exceptions for the years 2005, 2006, 2007, 2008 and 2011. PT-FI has filed objections to these assessments because it believes it has properly determined and paid its taxes.
During second-quarter 2014, the Indonesian tax authorities issued a tax assessment for 2012 and refunded $151 million (before foreign exchange adjustments) in August 2014 associated with income tax overpayments made by PT-FI ($303 million was included in other accounts receivable in the condensed consolidated balance sheets at December 31, 2013). PT-FI expects to file objections and use other means available under Indonesian tax laws and regulations to recover the remaining 2012 overpayments that it believes it is due.
As of June 30, 2014, PT-FI had $379 million included in other assets for amounts paid on disputed tax assessments, which it believes are collectable.

NOTE 10. BUSINESS SEGMENTS
FCX has organized its operations into six primary divisions – North America copper mines, South America mining, Indonesia mining, Africa mining, Molybdenum mines and U.S. oil and gas operations. Notwithstanding this structure, FCX internally reports information on a mine-by-mine basis for its mining operations. Therefore, FCX concluded that its operating segments include individual mines or operations relative to its mining operations. For oil and gas operations, FCX determines its operating segments on a country-by-country basis. Operating segments that meet certain thresholds are reportable segments, which are disclosed separately in the following tables.
Intersegment Sales. 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 mining operations to other divisions, including Atlantic Copper and on 25 percent of PT-FI's sales to PT Smelting until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX's net deferred profits and quarterly earnings.
Allocations. 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, 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.

NOTE 11. GUARANTOR FINANCIAL STATEMENTS
In March 2013, FCX completed the sale of $6.5 billion of senior notes. These notes, along with FCX's senior notes sold in February 2012, are fully and unconditionally guaranteed on a senior basis jointly and severally by FM O&G LLC, as guarantor, which is a 100 percent owned subsidiary of FM O&G and FCX. The guarantee is an unsecured obligation of the guarantor and ranks equal in right of payment with all existing and future indebtedness of FCX, including indebtedness under the revolving credit facility. The guarantee ranks senior in right of payment with all future subordinated obligations and is effectively subordinated in right of payment to any debt of FCX's subsidiaries that are not subsidiary guarantors. In the future, FM O&G LLC's guarantee may be released or terminated for certain obligations under the following circumstances: (i) all or substantially all of the equity interests or assets of FM O&G LLC are sold to a third party; or (ii) FM O&G LLC no longer has any obligations under any FM O&G senior notes or any refinancing thereof and no longer guarantees any obligations of FCX under the revolver, the term loan or any other senior debt.
The following condensed consolidating financial information includes information regarding FCX, as issuer, FM O&G LLC, as guarantor, and all other non-guarantor subsidiaries of FCX. Included are the condensed consolidating balance sheets at June 30, 2014, and December 31, 2013, and the related condensed consolidating statements of comprehensive income for the three and six months ended June 30, 2014 and 2013, and condensed consolidating statements of cash flows for the six months ended June 30, 2014 and 2013, which should be read in conjunction with FCX's notes to the consolidated financial statements (in millions). Certain amounts in the Condensed Consolidating Statement of Cash Flows for the six months ended June 30, 2013, have been reclassified to conform with the current period presentation. These amounts, which were not material, had no effect on the reported changes in cash and cash equivalents.

NOTE 12. NEW ACCOUNTING STANDARDS
In May 2014, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU), which outlines a single comprehensive model and supersedes most of the current revenue recognition guidance. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. Early adoption is not permitted. FCX is evaluating this new guidance, but does not expect it to have a significant impact on its current revenue recognition policies.
In April 2014, FASB issued an ASU, which revises the guidance for reporting discontinued operations. This ASU amends the definition of a discontinued operation and requires additional disclosures about disposal transactions that do not meet the definition of a discontinued operation. For public entities, this ASU is effective for annual periods beginning on or after December 15, 2014, and interim periods within that year. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. FCX adopted this ASU in the first quarter of 2014.

NOTE 13. SUBSEQUENT EVENTS
Mining Contract - Indonesia. On July 25, 2014, PT-FI entered into a Memorandum of Understanding (MOU) with the Indonesian government under which PT-FI and the government have agreed to negotiate an amended Contract of Work (COW) to address provisions related to the size of PT-FI’s concession area, royalties and taxes, domestic processing and refining, divestment, local content, and continuation of operations post-2021.
Under the MOU, provisions to be addressed in the negotiation of an amended COW include provisions for the development of new copper smelting and refining capacity in Indonesia, which will take into consideration an equitable sharing of costs between PT-FI (and any partners in the project) and the Indonesian government through fiscal incentives, provisions for divestment to the Indonesian government and/or Indonesian nationals of up to a 30 percent interest (an additional 20.64 percent interest) in PT-FI at fair value, and continuation of operations from 2022 through 2041. Negotiations will take into consideration PT-FI’s need for assurance of legal and fiscal terms post-2021 for PT-FI to continue with its large-scale investment program for the development of its underground reserves. The negotiations are expected to be completed within six months.
Effective with the signing of the MOU, PT-FI agreed to provide a $115 million assurance bond to support its commitment for smelter development, to increase royalties to 4.0 percent for copper and 3.75 percent for gold from the previous rates of 3.5 percent for copper and 1.0 percent for gold, and to pay export duties set forth in a new regulation. On July 25, 2014, the Indonesian government revised its January 2014 regulations (as discussed in Note 13 of FCX’s annual report on Form 10-K for the year ended December 31, 2013) regarding export duties to incorporate reduced rates for copper concentrate exports for companies engaged in smelter development. The revised regulations provide for duties on copper concentrate exports during smelter development initially at 7.5 percent, declining to 5.0 percent when development progress exceeds 7.5 percent and is eliminated when development progress exceeds 30 percent.
Under the MOU, no terms of the COW other than those relating to the export duties, smelter bond and royalties described previously will be changed until the completion of the amended COW.
FCX evaluated events after June 30, 2014, and through the date the consolidated financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these consolidated financial statements.

REVIEW REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF
FREEPORT-McMoRan INC.
We have reviewed the condensed consolidated balance sheet of Freeport-McMoRan Inc. (formerly Freeport-McMoRan Copper & Gold Inc.) a s of June 30, 2014, and the related consolidated statements of income and comprehensive income for the three- and six-month periods ended June 30, 2014 and 2013, the consolidated statements of cash flows for the six-month periods ended June 30, 2014 and 2013, and the consolidated statement of equity for the six-month period ended June 30, 2014. 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 condensed 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, 2013, and the related consolidated statements of income, comprehensive income, 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 27, 2014. In our opinion, the accompanying condensed consolidated balance sheet of Freeport-McMoRan Inc. as of December 31, 2013, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

OVERVIEW
Effective July 14, 2014, Freeport-McMoRan Copper & Gold Inc. changed its name to Freeport-McMoRan Inc. to simplify the corporate name and better reflect FCX's expanded portfolio of assets.
We are a premier U.S.-based natural resources company with an industry-leading global portfolio of mineral assets, significant oil and gas resources and a growing production profile. 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; significant mining operations in North and South America; the Tenke Fungurume (Tenke) minerals district in the Democratic Republic of Congo (DRC) in Africa; and significant oil and natural gas assets in the U.S., including reserves in the Deepwater Gulf of Mexico (GOM), onshore and offshore California, in the Haynesville shale play in Louisiana, in the Madden area in central Wyoming, and an industry-leading position in the emerging Inboard Lower Tertiary/Cretaceous natural gas trend in the shallow waters of the GOM and onshore in South Louisiana.
As further discussed in Note 2, in June 2014, we completed the sale of our Eagle Ford shale assets for $3.1 billion (before closing adjustments) and acquired additional interests in the Deepwater GOM for $0.9 billion. Refer to "Operations - Oil and Gas" for further discussion.
Our results for the second quarter and first six months of 2014 reflect the impact of restrictions on concentrate exports from Indonesia and a full six months of FCX Oil & Gas Inc. (FM O&G) results in 2014. Additionally, second-quarter 2013 was impacted by a temporary production suspension at PT Freeport Indonesia (PT-FI). Refer to "Consolidated Results" for further discussion of our consolidated financial results for the three- and six-month periods ended June 30, 2014 and 2013.
On July 25, 2014, PT-FI entered into a Memorandum of Understanding (MOU) with the Indonesian government under which, PT-FI and the government have agreed to negotiate an amended Contract of Work (COW), to be completed over the next six months, to address provisions related to the size of PT-FI’s concession area, royalties and taxes, domestic processing and refining, divestment, local content and continuation of operations post-2021. The MOU provides that negotiations for an amended COW will take into consideration PT-FI’s need for assurance of legal and fiscal terms post-2021 for PT-FI to continue with its large-scale investment program for the development of its underground reserves.
Execution of the MOU enabled the resumption of concentrate exports from PT-FI, which began in August 2014. Effective with the signing of the MOU, PT-FI has agreed to provide a $115 million assurance bond to support its commitment for smelter development, to increase royalties to 4.0 percent for copper and 3.75 percent for gold from the previous rates of 3.5 percent for copper and 1 percent for gold, and to pay export duties set forth in a new regulation. On July 25, 2014, the Indonesian government revised its January 2014 regulation regarding export duties to incorporate reduced rates for copper concentrate exports for companies engaged in smelter development. The revised regulations provide for duties on copper concentrate exports during smelter development initially at 7.5 percent, declining to 5 percent when development progress exceeds 7.5 percent, and is eliminated when development progress exceeds 30 percent. Refer to Note 13 and “Operations - Indonesia” for further discussion.
At June 30, 2014, we had $1.5 billion in consolidated cash and cash equivalents and $20.3 billion in total debt. On July 23, 2014, we redeemed $1.8 billion of senior notes, with an aggregate face value of $1.7 billion. We continue to target significant reductions in debt by the end of 2016 using cash flows generated above capital expenditures and

other cash requirements and potentially, net proceeds from asset sales. Refer to Note 6 and "Capital Resources and Liquidity" for further discussion.
OUTLOOK
We view the long-term outlook for our business positively, supported by limitations on supplies of copper and oil and by the requirements for copper and oil in the world’s economy. Our financial results vary as a result of fluctuations in market prices primarily for copper, gold, molybdenum and oil, as well as other factors. World market prices for these commodities have fluctuated historically 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 for our mining operations, cash production costs per barrel of oil equivalent (BOE) for our oil and gas operations and operating cash flow. The outlook for each of these measures follows.
Sales Volumes. Following are our projected consolidated sales volumes for the year 2014:

Copper (millions of recoverable pounds): |  |
North America copper mines | 1,700 |  |
South America mining | 1,200 |  |
Indonesia mining | 735 |  |
Africa mining | 440 |  |
| 4,075 |  |
Gold (thousands of recoverable ounces): |  |
Indonesia mining | 1,250 |  |
North and South America mining | 90 |  |
| 1,340 |  |
Molybdenum (millions of recoverable pounds) | 98 |  | a
Oil Equivalents (million BOE, or MMBOE) | 58.4 |  |

a. | Projected molybdenum sales include 53 million pounds produced by our Molybdenum mines and 45 million pounds produced by our North and South America copper mines.

Consolidated sales for third-quarter 2014 are expected to approximate 1.1 billion pounds of copper, 445 thousand ounces of gold, 23 million pounds of molybdenum and 12.2 MMBOE. Projected sales volumes are dependent on a number of factors, including operational performance and other factors.
Mining Unit Net Cash Costs. Assuming average prices of $1,300 per ounce of gold and $12 per pound of molybdenum for the second half of 2014, 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 $1.54 per pound of copper for the year 2014. These amounts include estimates of the new royalty rates and export duties at PT-FI. Quarterly unit net cash costs vary with fluctuations in sales volumes and average realized prices (primarily gold and molybdenum prices). The impact of price changes for the second half of 2014 on consolidated unit net cash costs would approximate $0.012 per pound for each $50 per ounce change in the average price of gold and $0.01 per pound for each $2 per pound change in the average price of molybdenum. Refer to “Consolidated Results – Production and Delivery Costs” for further discussion of consolidated production and delivery costs for our mining operations.
Oil and Gas Cash Production Costs per BOE. Based on current sales volume and cost estimates for the second half of 2014, cash production costs are expected to approximate $22 per BOE for the second half of 2014 and $20 per BOE for the year 2014. Refer to “Operations – Oil and Gas” for further discussion of oil and gas production costs.
Consolidated Operating Cash Flow. Our consolidated operating cash flows vary with prices realized from copper, gold, molybdenum and oil sales, our sales volumes, production costs, income taxes, other working capital changes and other factors. Based on current sales volume and cost estimates, including the new royalty rates and export duties at PT-FI, and assuming average prices of $3.25 per pound of copper, $1,300 per ounce of gold, $12 per pound of molybdenum and $110 per barrel of Brent crude oil for the second half of 2014, consolidated operating cash flows are estimated to approximate $6.7 billion for the year 2014 (net of $0.7 billion of working capital uses and changes in other tax payments). Projected consolidated operating cash flows for the year 2014 also reflect

estimated taxes of $1.7 billion (refer to “Consolidated Results – Provision for Income Taxes” for further discussion of our projected consolidated effective annual tax rate for 2014). The impact of price changes during the second half of 2014 on operating cash flows would approximate $200 million for each $0.10 per pound change in the average price of copper, $40 million for each $50 per ounce change in the average price of gold, $55 million for each $2 per pound change in the average price of molybdenum and $60 million for each $5 per barrel change in the price of Brent crude oil above $100 per barrel.
MARKETS
Metals. World prices for copper, gold and molybdenum can fluctuate significantly. During the period from January 2004 through July 2014, the London Metal Exchange (LME) spot copper price varied from a low of $1.06 per pound in 2004 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 $375 per ounce in 2004 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 $7.35 per pound in 2004 to a record high of $39.25 per pound in 2005. Copper, gold and molybdenum prices are affected by numerous factors beyond our control as described further in our “Risk Factors” contained in Part I, Item 1A of our annual report on Form 10-K for the year ended December 31, 2013.
This graph presents LME spot copper prices and the combined reported stocks of copper at the LME, Commodity Exchange Inc., a division of the New York Mercantile Exchange (NYMEX), and the Shanghai Futures Exchange from January 2004 through July 2014. From 2006 through most of 2008, limited supplies, combined with growing demand from China and other emerging economies, resulted in high copper prices and low levels of inventories. Current copper prices are supported by a combination of demand from developing economies and pro-growth monetary and fiscal policy decisions in Europe, China and the U.S. During the first half of 2014, copper prices declined because of concerns about slowing growth rates in China and an outlook for higher near-term supplies. During second-quarter 2014, LME spot copper prices ranged from a low of $2.99 per pound to a high of $3.19 per pound, averaged $3.08 per pound, and closed at $3.16 per pound on June 30, 2014.
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. 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. LME spot copper prices closed at $3.24 per pound on July 31, 2014.
This graph presents London PM gold prices from January 2004 through July 2014. An improving economic outlook and positive equity performance contributed to lower demand for gold in 2013 and early 2014, resulting in generally lower prices. During second-quarter 2014, London PM gold prices ranged from a low of $1,243 per ounce to a high of $1,326 per ounce, averaged $1,288 per ounce and closed at $1,315 per ounce on June 30, 2014. Gold prices closed at $1,285 per ounce on July 31, 2014.
This graph presents the Metals Week Molybdenum Dealer Oxide weekly average prices from January 2004 through July 2014. Molybdenum prices have improved during the first half of 2014, resulting from improved demand in the metallurgical sector. During second-quarter 2014, the weekly average price of molybdenum ranged from a low of $11.14 per pound to a high of $15.00 per pound, averaged $13.58 per pound and was $13.77 on June 30, 2014. The Metals Week Molybdenum Dealer Oxide weekly average price was $13.28 per pound on July 31, 2014.

Copper and gold sales volumes for the second quarter and first six months of 2014 reflect restrictions on concentrate exports from Indonesia, which resulted in a deferral of approximately 150 million pounds of copper and 240 thousand ounces of gold in second-quarter 2014 and 275 million pounds of copper and 380 thousand ounces of gold for the first six months of 2014. Partly offsetting these impacts were higher copper sales volumes from North America. Consolidated molybdenum sales volumes increased to 25 million pounds in second-quarter 2014 and 52 million pounds for the first six months of 2014, compared with 23 million pounds in second-quarter 2013 and 48 million pounds for the first six months of 2013. Refer to “Operations” for further discussion of sales volumes at our mining operations.

Metal Price Realizations
Our consolidated revenues can vary significantly as a result of fluctuations in the market prices of copper, gold and molybdenum. Following is a summary of our average price realizations from mining operations for the second quarters and first six months of 2014 and 2013:

| Three Months Ended |  | Six Months Ended
| June 30, |  | June 30,
| 2014 |  | 2013 |  | 2014 |  | 2013
Copper (per pound) | $ | 3.16 |  |  | $ | 3.17 |  |  | $ | 3.17 |  |  | $ | 3.29 |
Gold (per ounce) | $ | 1,296 |  |  | $ | 1,322 |  |  | $ | 1,299 |  |  | $ | 1,434 |
Molybdenum (per pound) | $ | 13.43 |  |  | $ | 12.35 |  |  | $ | 12.27 |  |  | $ | 12.56 |

We had lower copper and gold realizations in second-quarter 2014 and for the first six months of 2014, compared with second-quarter 2013 and the first six months of 2013. Realized molybdenum prices improved in second-quarter 2014, compared with second-quarter 2013. Refer to "Markets" for further discussion.
Provisionally Priced Copper Sales
During the first six months of 2014, 41 percent of our mined copper was sold in concentrate, 32 percent as cathode and 27 percent as rod from our North America operations. 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 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.
Following is a summary of the favorable (unfavorable) impacts of net adjustments to the prior periods' provisionally priced copper sales for the second quarters and first six months of 2014 and 2013 (in millions, except per share amounts):

| Three Months Ended |  | Six Months Ended
| June 30, |  | June 30,
| 2014 |  | 2013 |  | 2014 |  | 2013
Revenues | $ | 35 |  |  | $ | (117 | ) |  | $ | (118 | ) |  | $ | (26 | )
Net income attributable to common stockholders | $ | 16 |  |  | $ | (55 | ) |  | $ | (65 | ) |  | $ | (12 | )
Net income per share attributable to common stockholders | $ | 0.01 |  |  | $ | (0.06 | ) |  | $ | (0.06 | ) |  | $ | (0.01 | )

At June 30, 2014, we had provisionally priced copper sales at our copper mining operations, primarily South America and Indonesia, totaling 329 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $3.18 per pound, subject to final pricing over the next several months. We estimate that each $0.05 change in the price realized from the June 30, 2014, provisional price recorded would have an approximate $11 million impact on 2014 net income attributable to common stockholders. The LME spot copper price closed at $3.24 per pound on July 31, 2014.
Purchased Copper
From time to time, we purchase copper cathode for processing by our Rod & Refining segment when production from our North America copper mines does not meet customer demand.
Oil & Gas Revenues
FM O&G's realized revenues totaled $1.2 billion ($77.53 per BOE) in second-quarter 2014, $2.5 billion ($77.37 per BOE) for the first six months of 2014 and $372 million ($74.37 per BOE) for June 2013.

Consolidated sales of 16.0 MMBOE during second-quarter 2014 included 11.7 million barrels (MMBbls) of crude oil, 20.3 billion cubic feet (Bcf) of natural gas and 1.0 MMBbls of NGLs. Consolidated sales of 32.2 MMBOE for the first six months of 2014 included 23.5 MMBbls of crude oil, 39.8 Bcf of natural gas and 2.1 MMBbls of NGLs. Consolidated sales of 5.0 MMBOE during June 2013 included 3.4 MMBbls of crude oil, 7.7 Bcf of natural gas and 0.3 MMBbls of NGLs.
Refer to “Operations” for further discussion of realized revenues and sales volumes at our oil and gas operations.
In connection with the acquisition of Plains Exploration & Production Company (PXP) in June 2013, we have derivative contracts for 2014 and 2015 that consist of crude oil options and natural gas swaps at June 30, 2014. These crude oil and natural gas derivative contracts are not designated as hedging instruments; accordingly, they are recorded at fair value with the mark-to-market gains and losses recorded in revenues each period. Excluded from the realized revenues above are the following net noncash mark-to-market (losses) gains on crude oil and natural gas derivative contracts for the second quarter and first six months of 2014 and for June 2013 (in millions, except per share amounts):

Production and Delivery Costs
Consolidated production and delivery costs increased to $3.1 billion in second-quarter 2014 and $5.8 billion for the first six months of 2014, compared with $2.9 billion in second-quarter 2013 and $5.6 billion for the first six months of 2013. The increase in costs are primarily associated with production and delivery costs from our oil and gas operations beginning June 1, 2013, which totaled $329 million for second-quarter 2014, $640 million for the first six months of 2014 and $89 million for June 2013. Production and delivery costs for our mining operations for the second quarter and first six months of 2014 also reflected lower volumes from PT-FI related to restrictions on concentrate exports from Indonesia, while second-quarter 2013 production and delivery costs were impacted by a temporary suspension of operations at PT-FI.
Consolidated unit site production and delivery costs (before net noncash and other costs) for our copper mines of $1.99 per pound of copper in second-quarter 2014 and $1.94 per pound for the first six months of 2014, were lower than consolidated unit site production and delivery costs of $2.11 per pound in second-quarter 2013 and $2.02 per pound for the first six months of 2013 primarily reflecting higher North America sales volumes. Consolidated unit site production and delivery costs exclude fixed costs charged directly to cost of sales as a result of the impact of export restrictions on PT-FI's operating rates totaling $0.06 per pound of copper in the second quarter and first six months of 2014. Assuming achievement of current volume and cost estimates, consolidated unit site production and delivery costs are expected to average $1.95 per pound of copper for the year 2014. 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.
Our mining operations require significant energy, principally diesel, electricity, coal and natural gas, most of which is obtained from third parties under long-term contracts. Energy costs are expected to approximate 20 percent of our consolidated copper production costs for the year 2014, including purchases of approximately 270 million gallons of diesel fuel; 8,000 gigawatt hours of electricity at our North America, South America and Africa copper mining operations (we generate all of our power at our Indonesia mining operation); 655 thousand metric tons of coal for our coal power plant in Indonesia; and 1 MMBtu of natural gas at certain of our North America mines.
Cash production costs for our oil and gas operations of $19.57 per BOE in second-quarter 2014 and $19.03 for the first six months of 2014, were higher than $16.58 per BOE in June 2013, primarily reflecting higher operating costs in California.

Depreciation, Depletion and Amortization
Depreciation will vary under the unit-of-production (UOP) method as a result of changes in sales volumes and the related UOP rates at our mining and oil and gas operations. Consolidated depreciation, depletion and amortization expense totaled $1.0 billion in second-quarter 2014 and $2.0 billion for the first six months of 2014, compared with $530 million in second-quarter 2013 and $859 million for the first six months of 2013. Higher depreciation, depletion and amortization expense in the 2014 periods was primarily associated with depreciation, depletion and amortization costs from our oil and gas operations, which totaled $616 million for second-quarter 2014, $1.2 billion first six months of 2014 and $169 million for June 2013.
Selling, General and Administrative Expenses
Consolidated selling, general and administrative expenses totaled $164 million in second-quarter 2014 and $299 million for the first six months of 2014, compared with $186 million in second-quarter 2013 and $299 million for the first six months of 2013. Excluding amounts for our oil and gas operations, which totaled $59 million in second-quarter 2014, $116 million for the first six months of 2014 and $14 million for June 2013, selling, general and administrative expenses were lower in the 2014 periods primarily because of transaction costs incurred during 2013 associated with the oil and gas acquisitions.
Mining Exploration and Research Expenses
Consolidated exploration and research expenses for our mining operations totaled $34 million in second-quarter 2014 and $64 million for the first six months of 2014, compared with $64 million in second-quarter 2013 and $116 million for the first six months of 2013. We are actively conducting exploration activities near our existing mines with a focus on opportunities to expand reserves and resources to support development of additional future production capacity in the large mineral districts where we currently operate. Exploration results indicate opportunities for what we believe could be significant future potential reserve additions in North and South America, and in the Tenke minerals district. The drilling data in North America continues to indicate the potential for significantly expanded sulfide production.
For the year 2014, exploration and research expenditures for our mining operations are expected to approximate $135 million, including $100 million for exploration.
Under the full cost method of accounting, exploration costs for our oil and gas operations are capitalized to oil and gas properties.
Environmental Obligations and Shutdown Costs
Environmental obligation costs reflect net revisions to our long-term environmental obligations, which will 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 $76 million in second-quarter 2014 and $82 million for the first six months of 2014, compared with $16 million in second-quarter 2013 and $31 million for the first six months of 2013. Refer to Note 9 and "Contingencies" for further discussion of environmental obligations and litigation matters associated with closed facilities or operations.
Interest Expense, Net
Consolidated interest expense (excluding capitalized interest) increased to $225 million in second-quarter 2014 and $449 million for the first six months of 2014, compared with $167 million in second-quarter 2013 and $242 million for the first six months of 2013, reflecting additional interest expense associated with acquisition-related debt and assumed debt of PXP. Refer to Note 6 for further discussion.
Capitalized interest is related to the level of expenditures for our development projects and average interest rates on our borrowings, and totaled $61 million in second-quarter 2014 and $124 million for the first six months of 2014, compared with $35 million in second-quarter 2013 and $53 million for the first six months of 2013. Refer to “Capital Resources and Liquidity - Investing Activities” for further discussion of current development projects.

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

b. | Includes a $58 million charge for deferred taxes recorded in connection with the allocation of goodwill to the sale of Eagle Ford.

c. | Includes an $18 million charge to reflect increases in tax reserves related to prior periods.

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

e. | Reflects net reductions in our deferred tax liabilities and deferred tax asset valuation allowances resulting from the oil and gas acquisitions.

f. | Our consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which we conduct operations. Accordingly, variations in the relative proportions of jurisdictional income result in fluctuations to our consolidated effective income tax rate. Assuming average prices of $3.25 per pound for copper, $1,300 per ounce for gold, $12 per pound for molybdenum and Brent crude oil of $110 per barrel for the second half of 2014 and achievement of current sales volume and cost estimates, we estimate that our consolidated effective tax rate will approximate 34 percent for the year 2014.

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 85 percent joint venture interest in Morenci using the proportionate consolidation method.
The North America copper mines include open-pit mining, sulfide ore concentrating, leaching and solution extraction/electrowinning (SX/EW) operations. A majority of the copper produced at our North America copper mines is cast into copper rod by our Rod & Refining segment. The remainder of our North America copper sales is in the form of copper cathode or copper concentrate, a portion of which is shipped to Atlantic Copper (our wholly owned copper smelter). Molybdenum concentrate is also produced by certain of our North America copper mines.
Operating and Development Activities. We have increased production from our North America copper mines by approximately 25 percent over the past five years and continue to evaluate a number of opportunities to invest in additional production capacity following positive exploration results. Future investments will be undertaken based on the results of economic and technical feasibility studies and market conditions.
Morenci Mill Expansion. At Morenci, start-up activities from the expanded mill project began in second-quarter 2014. Commissioning activities commenced in May 2014, with a ramp up to full rates expected to be achieved by year-end 2014. The project targets average incremental annual production of approximately 225 million pounds of copper (an approximate 40 percent increase from 2013) through an increase in milling rates from 50,000 metric tons of ore per day to approximately 115,000 metric tons of ore per day. At full rates, Morenci's copper production is expected to approach 1 billion pounds in 2015, compared with 564 million pounds in 2013. At June 30, 2014, $1.5 billion had been incurred for this project ($0.4 billion during the first six months of 2014).
Construction of the new mill is substantially complete. Remaining items include completion of the molybdenum circuit, which would add capacity of approximately 9 million pounds of molybdenum per year, and the construction of an expanded tailings storage facility, which is expected to be completed in 2015.

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

Copper sales volumes from our North America copper mines increased to 423 million pounds in second-quarter 2014 and 794 million pounds for the first six months of 2014, compared with 372 million pounds in second-quarter 2013 and 725 million pounds for the first six months of 2013, reflecting higher milling rates and ore grades at several operating sites.
North America's copper production is expected to continue to increase during the second half of 2014 with the ramp up of the Morenci mill expansion project. Copper sales from our North America copper mines are expected to approximate 1.7 billion pounds for the year 2014, compared with 1.4 billion pounds in 2013. Refer to "Outlook" for projected molybdenum sales volumes.
Unit Net Cash Costs. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.
Gross Profit per Pound of Copper and Molybdenum

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

Our North America copper mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. Average unit net cash costs (net of by-product credits) of $1.70 per pound of copper in second-quarter 2014 and $1.74 per pound for the first six months of 2014, were lower than unit net cash costs of $1.92 per pound in second-quarter 2013 and $1.89 per pound for the first six months of 2013, primarily reflecting higher copper sales volumes.
Because certain assets are depreciated on a straight-line basis, North America's average unit depreciation rate may vary with asset additions and the level of copper production and sales.
Assuming achievement of current sales volume and cost estimates, and an average price of $12 per pound of molybdenum for the second half of 2014, average unit net cash costs (net of by-product credits) for our North America copper mines are expected to approximate $1.74 per pound of copper for the year 2014, compared with $1.87 per pound in 2013. North America's unit net cash costs for the remainder of 2014 would change by approximately $0.015 per pound for each $2 per pound change in the average price of molybdenum.
South America Mining
We operate four copper mines in South America – Cerro Verde in Peru and El Abra, Candelaria and Ojos del Salado in Chile. We own a 53.56 percent interest in Cerro Verde, a 51 percent interest in El Abra, and an 80 percent interest in the Candelaria and Ojos del Salado mining complex. All operations in South America are consolidated in our financial statements.
South America mining includes open-pit and underground mining, sulfide ore concentrating, leaching and SX/EW operations. Production from our South America mines is sold as copper concentrate or copper cathode under long-term contracts. Our South America mines ship a portion of their copper concentrate inventories to Atlantic Copper. In addition to copper, the Candelaria and Ojos del Salado mines produce gold and silver, and the Cerro Verde mine produces molybdenum concentrates.
Development Activities.
Cerro Verde Expansion. Construction activities associated with a large-scale expansion at Cerro Verde are in progress. Detailed project engineering and procurement are substantially complete and construction is advancing on schedule. The project will expand the concentrator facilities from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day and provide incremental annual production of approximately 600 million pounds of copper and 15 million pounds of molybdenum beginning in 2016. At June 30, 2014, $2.3 billion had been incurred for this project (approximately $0.8 billion during the first six months of 2014), with approximately $2.3 billion remaining to
46

be incurred. Considering the long-term nature and large size of the project, actual costs could vary from these estimates.
El Abra Sulfide. 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 be dependent on technical studies, economic factors and global copper market conditions.

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

Consolidated copper sales volumes from South America of 310 million pounds in second-quarter 2014 were slightly lower than second-quarter 2013 sales of 315 million pounds, primarily reflecting timing of shipments. South America's consolidated copper sales volumes increased to 617 million pounds for the first six months of 2014, compared with 600 million pounds for the first six months of 2013, primarily reflecting higher copper production from El Abra.
Consolidated sales volumes from South America mines are expected to approximate 1.2 billion pounds of copper for the year 2014, compared with sales of 1.3 billion pounds of copper in 2013, primarily reflecting lower ore grades at Candelaria and Cerro Verde. Refer to "Outlook" for projected gold and molybdenum sales volumes.
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.

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.
Assuming achievement of current sales volume and cost estimates, and average prices of $1,300 per ounce of gold and $12 per pound of molybdenum for the second half of 2014, we estimate that average unit net cash costs (net of by-product credits) for our South America mining operations would approximate $1.59 per pound of copper for the year 2014, compared with $1.43 per pound in 2013.
Indonesia Mining
Indonesia mining includes PT-FI’s Grasberg minerals district. We own 90.64 percent of PT-FI, including 9.36 percent owned through our wholly owned subsidiary, PT Indocopper Investama.
PT-FI operates a proportionately consolidated joint venture, which produces copper concentrates that contain significant quantities of gold and silver. Substantially all of PT-FI’s copper concentrates are sold under long-term contracts, of which approximately one-half is sold to Atlantic Copper and PT Smelting and the remainder to third-party customers.
We have established certain unincorporated joint ventures with Rio Tinto plc (Rio Tinto), under which Rio Tinto has a 40 percent interest in certain assets and future 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, 2013, for discussion of our joint ventures with Rio Tinto.
Refer to "Risk Factors" contained in Part II, Item 1A of this quarterly report and in Part I, Item 1A of our annual report on Form 10-K for the year ended December 31, 2013, for discussions of risks associated with operations in Indonesia.
Regulatory Matters. On July 25, 2014, PT-FI entered into a MOU with the Indonesian government under which PT-FI and the government have agreed to negotiate an amended COW, to address provisions related to the size of PT-FI’s concession area, royalties and taxes, domestic processing and refining, divestment, local content, and continuation of operations post-2021. Execution of the MOU enabled the resumption of concentrate exports, which began in August 2014.
Under the MOU, provisions to be addressed in the negotiation of an amended COW include provisions for the development of new copper smelting and refining capacity in Indonesia, which will take into consideration an equitable sharing of costs between PT-FI (and any partners in the project) and the Indonesian government through fiscal incentives, provisions for divestment to the Indonesian government and/or Indonesian nationals of up to a 30 percent interest (an additional 20.64 percent interest) in PT-FI at fair value, and continuation of operations from 2022 through 2041. The MOU provides that negotiations for an amended COW will take into consideration PT-FI’s need for assurance of legal and fiscal terms post-2021 for PT-FI to continue with its large-scale investment program for the development of its underground reserves. The negotiations are expected to be completed within six months.
Effective with the signing of the MOU, PT-FI agreed to provide a $115 million assurance bond to support its commitment for smelter development, to increase royalties to 4.0 percent for copper and 3.75 percent for gold from the previous rates of 3.5 percent for copper and 1.0 percent for gold, and to pay export duties set forth in a new regulation. On July 25, 2014, the Indonesian government revised its January 2014 regulations regarding export duties to incorporate reduced rates for copper concentrate exports for companies engaged in smelter development. The revised regulations provide for duties on copper concentrate exports during smelter development initially at 7.5 percent, declining to 5.0 percent when development progress exceeds 7.5 percent and is eliminated when development progress exceeds 30 percent.
Under the MOU, no terms of the COW other than those relating to the export duties, smelter bond and royalties described above will be changed until the completion of the amended COW.

Operating and Development Activities. We have several projects in progress in the Grasberg minerals district related to the development of the large-scale, long-lived, high-grade underground ore bodies. In aggregate, these underground ore bodies are expected to ramp up over several years to produce approximately 240,000 metric tons of ore per day following the transition from the Grasberg open pit, currently anticipated to occur in 2017. Over the next five years, estimated aggregate capital spending on these projects is currently expected to average $0.9 billion per year ($0.7 billion per year net to PT-FI). Considering the long-term nature and large size of these projects, actual costs could vary from these estimates. Additionally, PT-FI may reduce or defer these activities pending resolution of negotiations for an amended COW.
The following provides additional information on the continued development of the Common Infrastructure project, the Grasberg Block Cave underground mine and development of the Deep Mill Level Zone (DMLZ) ore body that lies below the Deep Ore Zone (DOZ) underground mine.
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. 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 more than 40 percent of our recoverable proven and probable reserves in Indonesia. Production at the Grasberg Block Cave mine is expected to commence in 2017, at the end of mining 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.
Aggregate mine development capital for the Grasberg Block Cave mine and associated Common Infrastructure is expected to approximate $5.2 billion (incurred between 2008 and 2021), with PT-FI’s share totaling approximately $4.6 billion. Aggregate project costs totaling $1.5 billion have been incurred through June 30, 2014 ($216 million during the first six months of 2014).
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. We plan to mine the ore body using a block-cave method with production beginning in 2015. Targeted production rates once the DMLZ mining operation reaches full capacity are expected to approximate 80,000 metric tons of ore per day. Drilling efforts continue to determine the extent of this ore body. Aggregate mine development capital costs for the DMLZ mine are expected to approximate $2.6 billion (incurred between 2009 to 2020), with PT-FI’s share totaling approximately $1.5 billion. Aggregate project costs totaling $1.0 billion have been incurred through June 30, 2014 ($149 million during the first six months of 2014).

Indonesia's sales volumes decreased to 117 million pounds of copper and 135 thousand ounces of gold for second-quarter 2014 and 226 million pounds of copper and 297 thousand ounces of gold for the first six months of 2014, compared with 158 million pounds of copper and 151 thousand ounces of gold for second-quarter 2013 and 356 million pounds of copper and 342 thousand ounces of gold for the first six months of 2013. As a result of the delay in obtaining approvals for 2014 exports, PT-FI implemented changes to its operations to align its concentrate production with PT Smelting’s operating plans. PT-FI’s milling rate averaged 102,900 metric tons of ore per day in second-quarter 2014 and 110,400 metric tons of ore per day for the first six months of 2014, which is approximately half of normal rates, and resulted in the deferral of approximately 150 million pounds of copper and 240 thousand ounces of gold in second-quarter 2014 and 275 million pounds of copper and 380 thousand ounces of gold for the first six months of 2014.
At the Grasberg mine, the sequencing of mining areas with varying ore grades causes fluctuations in quarterly and annual production of copper and gold. Consolidated sales volumes from our Indonesia mining operations are expected to approximate 0.7 billion pounds of copper and 1.25 million ounces of gold for 2014, compared with 0.9 billion pounds of copper and 1.1 million ounces of gold in 2013. Sales from Indonesia mining are expected to increase through 2016 as PT-FI gains access to higher grade ore.

net cash costs (net of gold and silver credits) totaled $2.66 per pound of copper in second-quarter 2014, $2.12 per pound of copper for the first six months of 2014, $2.71 per pound in second-quarter 2013 and $1.95 per pound of copper for the first six months of 2013. Indonesia's unit net cash costs exclude $0.48 per pound of copper in the second quarter and first six months of 2014 for fixed costs charged directly to cost of sales as a result of the impact of export restrictions on PT-FI's operating rates. PT-FI's unit net cash costs in second-quarter 2013 also reflect the impact of a temporary production suspension.
Treatment charges vary with the volume of metals sold and the price of copper, and royalties vary with the volume of metals sold and the prices of copper and gold.
Because certain assets are depreciated on a straight-line basis, PT-FI’s unit depreciation rate varies with the level of copper production 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 elimination of 25 percent of PT-FI's profit on sales to PT Smelting. Refer to "Operations - Smelting & Refining" for further discussion.
Based on current sales volume and cost estimates, including the new royalty rates and export duties, and assuming an average gold price of $1,300 per ounce for the second half of 2014, Indonesia's unit net cash costs (net of gold and silver credits) are expected to approximate $1.17 per pound of copper for the year 2014, compared with $1.12 for the year 2013. Indonesia's projected unit net cash costs would change by approximately $0.07 per pound for each $50 per ounce change in the average price of gold for the second half of 2014. 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.
Africa Mining
Africa mining includes Tenke Fungurume Mining S.A.R.L's (TFM) Tenke minerals district. We hold an effective 56 percent interest in the Tenke copper and cobalt mining concessions in the Katanga province of the DRC through our consolidated subsidiary TFM, and we are the operator of Tenke.
The Tenke operation includes surface mining, leaching and SX/EW operations. Copper production from the Tenke minerals district is sold as copper cathode. In addition to copper, the Tenke minerals district produces cobalt hydroxide.
Operating and Development Activities. TFM completed its second phase expansion project in early 2013, which included increasing mine, mill and processing capacity. The expanded mill's throughput rates averaged 15,200 metric tons per day for second-quarter 2014, compared with the project's design capacity of 14,000 metric tons of ore per day. We continue to engage in exploration activities and metallurgical testing to evaluate the potential of the highly prospective minerals district at Tenke. These analyses are being incorporated in future plans for potential expansions of production capacity. Future expansions are subject to a number of factors, including economic and market conditions, and the business and investment climate in the DRC.

TFM's copper sales totaled 118 million pounds in second-quarter 2014, 106 million pounds in second-quarter 2013, 202 million pounds for the first six months of 2014 and 224 million pounds for the first six months of 2013. TFM's copper sales reflected lower grade ore in the 2014 periods. Higher sales volumes for second-quarter 2014, compared with second-quarter 2013, were because of timing of shipments.
For the year 2014, we expect sales volumes from TFM to approximate 440 million pounds of copper and 30 million pounds of cobalt, compared with 454 million pounds of copper and 25 million pounds of cobalt for the year 2013.
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.

Table of Contents
Assuming achievement of current sales volume and cost estimates, and an average cobalt market price of $13 per pound for the second half of 2014, average unit net cash costs (net of cobalt credits) are expected to approximate $1.21 per pound of copper for the year 2014, compared with $1.21 per pound in 2013. Africa's projected unit net cash costs would change by $0.045 per pound for each $2 per pound change in the average price of cobalt during the second half of 2014.
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 concentrates, which are typically further processed into value-added molybdenum chemical products. The majority of the molybdenum concentrates produced at the Henderson and Climax mines, as well as from certain of our North and South America copper mines, are processed at our own conversion facilities.

a. | Revenues reflect sales of the Molybdenum mines' production to our molybdenum sales company at market-based pricing. On a consolidated basis, realizations are based on actual contract terms of sales made to third parties. As a result, our consolidated average realized price per pound of molybdenum (refer to "Consolidated Results") will differ from the amounts reported in this table.

Average unit net cash costs for our Molybdenum mines decreased to $6.47 per pound of molybdenum in second-quarter 2014 and $6.58 per pound for the first six months of 2014, compared with $6.79 per pound in second-quarter 2013 and $7.05 per pound for the first six months of 2013, primarily reflecting higher production volumes. Assuming achievement of current sales volume and cost estimates, unit net cash costs for our Molybdenum mines are expected to average approximately $7.00 per pound of molybdenum for the year 2014.
Smelting & Refining
Smelting and refining charges consist of a base rate and, in certain contracts, price participation based on copper prices. Treatment charges for smelting and refining copper concentrates represent a cost to our mining operations, and income to Atlantic Copper and PT Smelting. Thus, higher treatment and refining charges benefit our smelter operations and adversely affect our mining operations. Our North America copper mines are less significantly affected by changes in treatment and refining charges because these operations are largely integrated with our wholly owned smelter located in Miami, Arizona.
Atlantic Copper, our wholly owned subsidiary located in Spain, smelts and refines copper concentrates and markets refined copper and precious metals in slimes. During the first six months of 2014, Atlantic Copper purchased 31 percent of its concentrate requirements from our North America mining operations, 22 percent from our South America copper mines and 4 percent from our Indonesia mining operations (prior to implementation of the export restrictions), with the remainder purchased from third parties. Through this form of downstream integration, we are assured placement of a significant portion of our concentrate production.
We defer recognizing profits on sales from our mining operations to Atlantic Copper and on 25 percent of Indonesia mining'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 stockholders totaling $41 million in second-quarter 2014 and $56 million for the first six months of 2014, compared with $2 million in second-quarter 2013 and $27 million for the first six months of 2013. Our net deferred profits on inventories at Atlantic Copper and PT Smelting to be recognized in future periods’ net income attributable to common stockholders totaled $36 million at June 30, 2014. 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. As PT-FI's sales volumes increase, in third-quarter 2014 we expect to defer approximately $50 million of profit on intercompany sales until final sales to third parties occur.

Oil and Gas
In second-quarter 2013, we acquired oil and gas operations by completing the acquisitions of PXP and MMR, collectively FM O&G. Our oil and gas operations provide exposure to energy markets with positive fundamentals, strong margins and cash flows and a large resource base with financially attractive exploration and development investment opportunities. The portfolio of assets includes significant oil production facilities and growth potential in the Deepwater GOM, established oil production onshore and offshore California, large onshore natural gas resources in the Haynesville shale play in Louisiana, natural gas production from the Madden area in central Wyoming, and an industry-leading position in the emerging Inboard Lower Tertiary/Cretaceous natural gas trend located in the shallow waters of the GOM and onshore in South Louisiana. More than 90 percent of our oil and gas revenues are from oil and NGLs.
Our oil and gas operations follow the full cost method of accounting whereby all costs associated with oil and gas property acquisition, exploration and development activities are capitalized into cost centers on a country-by-country basis. Capitalized costs, along with estimated future costs to develop proved reserves, are amortized to expense under the unit-of-production method using estimates of the related proved oil and natural gas reserves. The costs of unproved oil and gas properties are excluded from amortization until the properties are evaluated, at which time the related costs are transferred to the full cost pool and become subject to amortization. Our depletion, depreciation and amortization rate is affected by changes to estimates of proved reserves and costs subject to amortization, as further discussed in "Critical Accounting Estimates" in Part II, Item 7 and 7a of our annual report on Form 10-K for the year ended December 31, 2013.
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. As of June 30, 2014, the ceiling with respect to our U.S. oil and gas properties exceeded the related net capitalized costs by approximately 1 percent. As further discussed in "Critical Accounting Estimates" in Part II, Item 7 and 7a of our annual report on Form 10-K for the year ended December 31, 2013, events that could result in impairment of our oil and gas properties in future periods include, but are not limited to, a decline in trailing average oil and gas prices, transfers of costs into the full cost pool without equivalent increased reserve values, increased costs or negative reserve revisions. In the near term, FM O&G expects to conduct significant completion activities to assess certain of its unevaluated properties. As these assessments are completed, related costs currently recorded as unevaluated properties not subject to amortization will be transferred into the full cost pool. If these activities do not result in additions to discounted future net cash flows from proved oil and natural gas reserves at least equal to the related costs transferred (net of related tax effects), a ceiling test impairment may occur. A ceiling test impairment may also trigger an impairment assessment of our goodwill balance, which totaled $1.7 billion at June 30, 2014, and is assigned to our U.S. oil & gas reporting unit.
Sale and Purchase Transactions. On June 20, 2014, we completed the sale of the Eagle Ford shale assets for cash consideration of $3.1 billion, before closing adjustments from the effective date of April 1, 2014. Under full cost accounting rules, the proceeds from this transaction were accounted for as a reduction to capitalized costs, with no gain or loss recognition, except for $58 million of deferred tax expense recorded in connection with the allocation of goodwill to the sale of Eagle Ford. FM O&G's Eagle Ford interests included approximately 45,500 net acres with estimated net proved reserves of 59 MMBOE and estimated net proved and probable reserves of 69 MMBOE at year-end 2013. FM O&G's second-quarter 2014 results included 4.0 MMBOE of sales volumes from Eagle Ford through June 19, 2014.
Approximately $1.3 billion of proceeds from the sale of the Eagle Ford shale assets was placed in a like-kind exchange escrow to reinvest into additional oil and gas interests. On June 30, 2014, $0.9 billion from this like-kind exchange escrow was used to complete the acquisition of interests in the Deepwater GOM, including interests in the Lucius and Heidelberg oil production development projects and several exploration leases. The remaining $0.4 billion of funds in the like-kind exchange escrow may be used to acquire additional interests in the Deepwater GOM on a tax-efficient basis.
Exploration and Development Activities. Our oil and gas business has significant proved, probable and possible reserves and a broad range of development opportunities and high-potential exploration prospects. The business is being managed to reinvest its cash flows in projects with attractive rates of return and risk profiles.
FM O&G has a large, strategic position in the Deepwater GOM with significant current oil production, strong cash margins and existing infrastructure and facilities with excess capacity. These assets, combined with FM O&G’s large leasehold interests in an established geologic basin, provide financially attractive investment opportunities for high-impact growth in oil production and cash margins. Following the sale of the Eagle Ford shale assets on June

20, 2014, FM O&G’s capital allocation strategy is principally focused on exploitation drilling and development opportunities that can be tied back to existing facilities in the Deepwater GOM. Additional oil and gas asset sales are being considered to provide additional funding to accelerate FM O&G’s growth plans in the Deepwater GOM.
Capital expenditures for our oil and gas operations approximated $0.9 billion for second-quarter 2014, including $0.5 billion incurred for the Deepwater GOM and $0.2 billion for the Inboard Lower Tertiary/Cretaceous natural gas trend, and $1.5 billion for the first six months of 2014, including $0.8 billion incurred for the Deepwater GOM and $0.3 billion for the Inboard Lower Tertiary/Cretaceous natural gas trend. Capital expenditures for our oil and gas operations, which are expected to be funded by its operating cash flows and proceeds from oil and gas asset sales, are projected to approximate $3.4 billion for the year 2014, including $1.8 billion for the Deepwater GOM and $0.7 billion for the Inboard Lower Tertiary/Cretaceous natural gas trend. Our future capital spending estimates may be adjusted to incorporate results from our ongoing drilling activities and follow-on development activities.
See "Financial and Operating Data" below for further discussion of our current oil and gas operations.

a. | The 2014 periods include results from Eagle Ford through June 19, 2014.

b. | The 2013 periods include the results of FM O&G beginning June 1, 2013.

c. | Cash operating margin for our oil and gas operations reflects realized revenues less cash production costs. Realized revenues exclude noncash mark-to-market adjustments on derivative contracts, and cash production costs exclude accretion and other costs. For reconciliations of realized revenues (including average realizations for oil, natural gas and NGLs) and cash production costs per BOE to revenues and production and delivery costs reported in our consolidated financial statements, refer to "Product Revenues and Production Costs."

Realized revenues for our oil and gas operations totaled $1.2 billion ($77.53 per BOE) in second-quarter 2014, $2.5 billion ($77.37 per BOE) for the first six months of 2014 and $372 million ($74.37 per BOE) in June 2013. Cash production costs totaled $314 million ($19.57 per BOE) in second-quarter 2014, $612 million ($19.03 per BOE) for the first six months of 2014 and $83 million ($16.58 per BOE) in June 2013. Based on current sales volume and cost estimates for the second half of 2014, cash production costs are expected to approximate $22 per BOE for the second half of 2014, which is higher than the estimate previously reported in our quarterly report on Form 10-Q for the quarter ended March 31, 2014, primarily reflecting lower estimated volumes because of the sale of the Eagle Ford shale assets.

a. | Reflects the results of our oil and gas operations beginning June 1, 2013.

b. | Includes sales from properties on the GOM Shelf and in the Deepwater GOM. Production from the GOM Shelf totaled 12 MBOE per day in the second quarter and first six months of 2014 (15 percent of the GOM total in second-quarter 2014 and 16 percent for the first six months of 2014), and 15 MBOE per day (22 percent of the GOM total) in June 2013.

c. | Includes results of the Eagle Ford field through June 19, 2014.

Daily sales volumes averaged 176 MBOE in second-quarter 2014, including 128 MBbls of crude oil, 223 million cubic feet (MMcf) of natural gas and 11 MBbls of NGLs, and 178 MBOE for the first six months of 2014, including 130 MBbls of crude oil, 220 MMcf of natural gas and 11 MBbls of NGLs. Oil and gas sales volumes are expected to average 142 MBOE per day for the second half of 2014, comprised of 69 percent oil, 27 percent natural gas and 4 percent NGLs.
Deepwater Gulf of Mexico. Multiple development and exploration opportunities have been identified in the Deepwater GOM that are expected to benefit from tie-back opportunities to available production capacity at the FM O&G operated large-scale Holstein, Marlin and Horn Mountain deepwater production platforms. Operations to pursue these opportunities have commenced and activities are expected to accelerate following the delivery of contracted drill ships over the next 12 months.
The U.S. Bureau of Ocean Energy Management (BOEM) has awarded FM O&G all 20 leases from its March 2014 Central Gulf of Mexico Lease Sale 231. The blocks, which range in water depths up to 6,000 feet and cover approximately 106,000 gross acres, are primarily focused on high-impact, drillable targets in the Mississippi Canyon, Atwater Valley and Green Canyon areas, and complement FM O&G’s existing infrastructure and production facilities, as well as add several new exploration plays.
Holstein, in which FM O&G has a 100 percent working interest, is located in Green Canyon and has production facilities capable of producing in excess of 100 MBOE per day. Drilling from the Holstein platform rig commenced in first-quarter 2014. In June 2014, the first sidetrack well commenced production at a rate of approximately 3,600 BOE per day and completion of the second successful sidetrack well is under way. Over the 2014 to 2016 period, FM O&G expects to drill five additional sidetrack wells from the Holstein platform following the current sidetrack well. During this period, FM O&G also plans to drill five subsea tie-back wells from contracted drillships to enhance production volumes from the spar. Near-term tie-back prospects in the Holstein area include Holstein Deep and Copper.

Table of Contents
The Holstein Deep development, in which FM O&G has a 100 percent working interest, is located four miles west of the Holstein platform. FM O&G acquired the acreage associated with this development in a 2013 lease sale held by the BOEM. Two successful wells had previously been drilled in recent years, which encountered approximately 500 net feet of oil pay. Delineation drilling on this prospect is expected to commence in third-quarter 2014.
The Copper exploration prospect commenced drilling in July 2014 and is currently drilling below 6,800 feet towards a proposed total depth of 14,500 feet. Copper is located southeast of the Holstein field in 4,400 feet of water and is a subsea tie-back opportunity to the Holstein facility. The prospect is a Holstein analog play with Pliocene objectives, and FM O&G has a 100 percent working interest.
Development of the Lucius field in Keathley Canyon is on track with first oil production anticipated in fourth-quarter 2014. All major construction and installation projects are complete. The geologic results from the six wells drilled since 2009 confirm a significant oil resource. The sanctioned development of Lucius is a subsea development consisting of a truss spar hull located in 7,200 feet of water with a topside daily capacity of 80 MBbls of oil and 450 MMcf of gas. FM O&G has a 25.1 percent working interest in Lucius.
Development of the Heidelberg field in Green Canyon is in progress and production is expected to commence in mid-2016. Heidelberg is a large, high-quality oil development project located in 5,300 feet of water. The hull fabrication for the 80 MBbls of oil per day Lucius-look-alike facility is substantially complete, and the spar is expected to be towed to the GOM later this year. Topside fabrication is 40 percent complete. Development drilling commenced in third-quarter 2014 for the first of six development wells to be drilled through 2016. FM O&G has a 12.5 percent working interest in Heidelberg.
In second-quarter 2014, FM O&G drilled the Tara exploration prospect, located in Keathley Canyon in 8,700 feet of water, to approximately 20,800 feet. In July 2014, the well was evaluated and determined not to contain commercial quantities of hydrocarbons.
Inboard Lower Tertiary/Cretaceous. FM O&G has an industry-leading position in the emerging Inboard Lower Tertiary/Cretaceous natural gas trend, located on the Shelf of the GOM and onshore in South Louisiana. FM O&G has a large onshore and offshore lease acreage position with high-quality prospects and the potential to develop a significant long-term, low-cost source of natural gas. Data from eight wells drilled to date indicate the presence of geologic formations that are analogous to productive formations in the Deepwater GOM and onshore in the Gulf Coast region. The near-term focus is on defining the trend onshore with plans to spud three prospects by year-end 2014. FM O&G is currently completing the Highlander and Blackbeard West No. 2 Inboard Lower Tertiary/Cretaceous exploration prospects and plans to perform production tests on these two wells in 2014.
The Highlander onshore exploratory well, in which FM O&G is the operator and has a 72 percent working interest, located in St. Martin Parish, Louisiana, encountered gas pay in several Wilcox and Cretaceous/Tuscaloosa sands between 24,000 feet and 29,000 feet. As reported in our annual report on Form 10-K for the year ended December 31, 2013, the wireline log and core data obtained from the Wilcox and Cretaceous sand packages indicated favorable reservoir characteristics with approximately 150 feet of net pay. The Highlander discovery well is currently in completion operations to test Cretaceous/Tuscaloosa objectives found below the salt weld. Flow testing is anticipated in the second half of 2014. FM O&G has identified multiple exploratory prospects in the Highlander area where it controls rights to approximately 57,000 gross acres.
Completion operations at Blackbeard West No. 2, in which FM O&G has a 69.4 percent working interest, located on Ship Shoal Block 188 are in progress. Other near-term drilling includes the Farthest Gate West exploratory prospect located onshore in Cameron Parish, Louisiana. Farthest Gate West is a Lineham Creek analog prospect with Paleogene objectives and has a proposed total depth of 25,000 feet.
During second-quarter 2014, a flow test was performed on the deepest sand section (Cretaceous/Tuscaloosa) in Davy Jones No. 2, in which FM O&G has a 75 percent working interest. The test of this section, one of two potentially productive intervals in the well, did not result in hydrocarbon production in commercial quantities, and the well was temporarily abandoned. Testing of the remaining sand sections (Wilcox) was deferred until later in 2014 in order to use the completion equipment to accelerate the completion and testing of the Highlander well. The Davy Jones No. 2 flow test provided valuable data, including confirmation of permeability of the sands, which we believe is encouraging in relation to the Tuscaloosa discovery at Highlander and other Inboard Lower Tertiary/Cretaceous prospects.

California. FM O&G's California assets benefit from an established oil production base with a stable production profile and access to favorably priced crude markets. Development plans are principally focused on maintaining stable production levels through continued drilling in the long-established producing fields onshore in California. FM O&G's position in California is located onshore in the San Joaquin Valley and Los Angeles Basin and offshore in the Point Arguello and Point Pedernales fields.
Haynesville. FM O&G has rights to a substantial natural gas resource, located in the Haynesville shale play in North Louisiana. Drilling activities in recent years have been reduced to maximize cash flows in a low natural gas price environment and to benefit from potentially higher future natural gas prices.
CAPITAL RESOURCES AND LIQUIDITY
Our operating cash flows vary with prices realized from copper, gold, molybdenum and oil, our sales volumes, production costs, income taxes, other working capital changes and other factors. We continue to target significant reductions in debt by the end of 2016 using cash flows generated above capital expenditures and other cash requirements. We have taken steps to accelerate our deleveraging plans through asset sales, and will continue to evaluate our portfolio for potential future monetizations. We may also take additional steps to defer capital spending and other costs in response to market conditions.
Cash
Following is a summary of the U.S. and international components of consolidated cash and cash equivalents, including cash available to the parent company, net of noncontrolling interests' share, taxes and other costs at June 30, 2014 (in millions):

Cash at domestic companies | $ | 700 |  |
Cash at international operations | 758 |  |
Total consolidated cash and cash equivalents | 1,458 |  |
Less: noncontrolling interests’ share | (333 | ) |
Cash, net of noncontrolling interests’ share | 1,125 |  |
Less: withholding taxes and other | (42 | ) |
Net cash available | $ | 1,083 |  |

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 (refer to Note 6). With the exception of TFM, 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 June 30, 2014 (in billions, except percentages):

|  |  | Weighted- |
|  |  | Average |
|  |  | Interest Rate |
Acquisition-related debt | $ | 10.4 |  |  | 3.1% |
Assumed debt of PXP | 6.4 |  | a | 6.8% | a
Other FCX debt | 3.5 |  |  | 3.4% |
| $ | 20.3 |  |  | 4.2% |

a. On July 23, 2014, we redeemed senior notes with a book value of $1.8 billion and a weighted-average interest rate of 6.6 percent under the equity clawback provisions of the instruments. Available cash and borrowings of approximately $950 million under the revolving credit facility and uncommitted lines of credit were used to fund the redemption. Holders received the principal amount of $1.7 billion together with the redemption premium and accrued and unpaid interest to the redemption date. We will report a gain on early extinguishment of debt of $58 million in third-quarter 2014 associated with these redemptions.

On May 30, 2014, we amended our revolving credit facility, extending the maturity date by one year, to May 31, 2019, and increased the aggregate principal amount available from $3.0 billion to $4.0 billion. At June 30, 2014, we had no borrowings outstanding and $46 million of letters of credit issued under our revolving credit facility.
We have uncommitted unsecured short-term lines of credit with certain financial institutions, which have terms and pricing that are more favorable than our revolving credit facility. As of June 30, 2014, there were no borrowings drawn on these lines of credit.
In March 2014, Cerro Verde entered into a five-year, $1.8 billion senior unsecured credit facility. Amounts may be drawn over a two-year period to fund a portion of the expansion project (see "Operations - South America Mining") and for Cerro Verde's general corporate purposes. At June 30, 2014, there were no borrowings and no letters of credit issued under Cerro Verde’s credit facility.
Refer to Note 6 for further discussion of our debt.
Operating Activities
During the first six months of 2014, we generated consolidated operating cash flows totaling $2.6 billion (net of $777 million for working capital uses and changes in other tax payments), compared with consolidated operating cash flows for the first six months of 2013 of $1.9 billion (net of $195 million for working capital uses and changes in other tax payments). Consolidated operating cash flows for the first six months of 2014 benefited from a full six months of our oil and gas operations, partly offset by the impact of lower metals price realizations, lower copper sales volumes and an increase in working capital uses and changes in other tax payments, primarily associated with accounts receivable. As discussed in "Consolidated Results - Revenues," substantially all of our copper concentrate and cathode sales contracts are provisionally priced; accordingly, the quarter-end forward price is a major determinant of recorded revenues and the resulting receivables. At June 30, 2014, we had provisionally priced copper sales of 329 million pounds recorded at an average of $3.18 per pound, compared with 306 million pounds of copper recorded at an average of $3.06 per pound at June 30, 2013.
Based on current operating plans and subject to future copper, gold, molybdenum and crude oil prices, we expect estimated consolidated operating cash flows for the year 2014, plus available cash and availability under our revolving credit facility and uncommitted lines of credit, to be sufficient to fund our budgeted capital expenditures, dividends, noncontrolling interest distributions and other cash requirements for the year. Refer to “Outlook” for further discussion of projected operating cash flows for the year 2014.
Investing Activities
Capital Expenditures. Capital expenditures, including capitalized interest, totaled $3.6 billion for the first six months of 2014, including $1.4 billion for major projects at mining operations and $1.5 billion for oil and gas operations, compared with $2.0 billion for the first six months of 2013, including $1.0 billion for major projects and $0.2 billion for oil and gas operations beginning June 1, 2013. Increased capital expenditures for our mining operations for the first six months of 2014 is primarily associated with the expansion project at Cerro Verde. Refer to “Operations” for further discussion.
Capital expenditures are currently expected to approximate $7.6 billion for the year 2014, including $3.2 billion for major projects at mining operations and $3.4 billion for oil and gas operations. Major projects at our mining operations for 2014 primarily include the Cerro Verde and Morenci expansion projects, and underground development activities at Grasberg. Capital spending plans remain under review and will be revised as market conditions warrant. Refer to "Operations" for further discussion.
Acquisitions and Dispositions. In June 2014, we acquired additional interests in the Deepwater GOM, for $0.9 billion, and also completed the sale of our Eagle Ford shale assets for $3.1 billion (before closing adjustments). The Deepwater GOM acquisition was funded with a portion of the net proceeds from the sale of Eagle Ford. The estimated combined after-tax net proceeds from these transactions approximated $1.8 billion, before purchase price adjustments. Refer to Note 2 for further discussion of our acquisition and disposal transactions.
In second-quarter 2013, we paid $3.5 billion in cash (net of cash acquired) for the acquisition of PXP and $1.6 billion in cash (net of cash acquired) for the acquisition of MMR. Refer to Note 2 for further discussion of our acquisition and disposal transactions.

Table of Contents
In March 2013, we paid $321 million (net of cash acquired) to fund the acquisition of a cobalt chemical refinery in Kokkola, Finland, and the related sales and marketing business. The acquisition was funded 70 percent by us and 30 percent by Lundin Mining Corporation, our joint venture partner.
Financing Activities
Debt Transactions. On April 30, 2014, we redeemed $210 million of the aggregate principal amount of the outstanding 6.625% Senior Notes. Holders received the principal amount together with the redemption premium and accrued and unpaid interest to the redemption date. Refer to Note 6 for further discussion of debt transactions for the first six months of 2014.
Proceeds from debt for the first six months of 2013 primarily included amounts from the sale of $6.5 billion of unsecured senior notes in four tranches with a weighted-average interest rate of 3.9 percent and borrowings of $4.0 billion under an unsecured term loan with an interest rate of LIBOR plus 1.5 percent. Net proceeds from these borrowings were used to fund the second-quarter 2013 oil and gas acquisitions, repay certain debt of PXP and for general corporate purposes. Repayments of debt for the first six months of 2013 primarily reflected the repayment of the $3.9 billion outstanding under PXP's amended credit facility and $0.4 billion of PXP senior notes that were assumed in the oil and gas acquisitions.
Dividends. We paid dividends on our common stock totaling $653 million for first six months of 2014 and $595 million for first six months of 2013. The current annual dividend rate for our common stock is $1.25 per share ($0.3125 per share quarterly). The declaration of dividends is at the discretion of our Board of Directors (Board) and will depend upon our financial results, cash requirements, future prospects and other factors deemed relevant by the Board. The Board will continue to review our financial policy on an ongoing basis.
Cash dividends and other distributions paid to noncontrolling interests totaled $250 million for first six months of 2014 and $90 million for first six months of 2013. These payments will vary based on the cash requirements of our consolidated subsidiaries.
CONTRACTUAL OBLIGATIONS
Except as discussed in Note 13, there have been no material changes in our contractual obligations since December 31, 2013. Refer to Item 7 in our annual report on Form 10-K for the year ended December 31, 2013, for further information regarding our contractual obligations.
CONTINGENCIES
Environmental and Asset Retirement Obligations
Our current and historical operating activities are subject to stringent laws and regulations governing the protection of the environment. We perform a comprehensive annual review of our environmental and asset retirement obligations and also review changes in facts and circumstances associated with these obligations at least quarterly. There have been no material changes to our environmental and asset retirement obligations since December 31, 2013. Updated cost assumptions, including increases and decreases to cost estimates, changes in the anticipated scope and timing of remediation activities and settlement of environmental matters may result in revisions to certain of our environmental obligations.
Refer to Note 12 in our annual report on Form 10-K for the year ended December 31, 2013, for further information regarding our environmental and asset retirement obligations.

NEW ACCOUNTING STANDARDS
We do not expect the impact of recently issued accounting standards to have a significant impact on our future financial statements and disclosures.
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, (iv) it is the method used to compare mining operations in certain industry publications and (v) it is the method used by our management and the Board to monitor operations. In the co-product method presentation 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, we have reflected these separately from revenues on current period sales. Noncash and other costs consist of items such as stock-based compensation costs, start-up costs, write-offs of equipment and/or unusual charges. They are removed from site production and delivery costs in the calculation of unit net cash costs. 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 for our mining operations are presentations under both the by-product and co-product methods together with reconciliations to amounts reported in our consolidated financial statements.
U.S. Oil & Gas Product Revenues and Cash Production Costs per Unit
Realized revenues and cash production costs per unit are measures intended to provide investors with information about the cash operating margin of our oil and gas operations. We use this measure for the same purpose and for monitoring operating performance by our oil and gas 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. Our measures may not be comparable to similarly titled measures reported by other companies.
We show revenue adjustments from derivative contracts as separate line items. Because these adjustments do not result from oil and gas sales, these gains and losses have been reflected separately from revenues on current period sales. Additionally, accretion and other costs are removed from production and delivery costs in the calculation of cash production costs per BOE. The following schedules include calculations of oil and gas product revenues and cash production costs together with a reconciliation to amounts reported in our consolidated financial statements.

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 (FMC - formerly Freeport-McMoRan 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 12 and incorporated by reference into Part I, Item 3. “Legal Proceedings” of our annual report on Form 10-K for the year ended December 31, 2013, as updated in Note 9 to the financial statements included in our quarterly report on Form 10-Q for the quarter ended March 31, 2014, 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 “Because our Grasberg minerals district is our most significant operating asset, our business may continue to be adversely affected by political, economic and social uncertainties and security risks in Indonesia”, which was included in FCX’s annual report on Form 10-K for the year ended December 31, 2013, is amended to add the following:
PT Freeport Indonesia (PT-FI) has been engaged in discussions with officials of the Indonesian government since 2012 regarding various provisions of its Contract of Work (COW). The government has sought to modify existing mining contracts, including PT-FI’s COW, to address provisions of Indonesia’s 2009 mining law and subsequent regulations, including with respect to the size of contract concessions, government revenues, domestic processing of minerals, divestment, provision of local services, and conversion from a COW to a licensing framework for extension periods, and a requirement that extensions may be applied for only within two years prior to a COW’s expiration.
In January 2014, the Indonesian government published regulations providing that holders of contracts of work with existing processing facilities in Indonesia may continue to export product through January 12, 2017, but established new requirements for the continued export of copper concentrates, including the imposition of a progressive export duty on copper concentrates in the amount of 25 percent in 2014, rising to 60 percent by mid-2016. Regulations
88

Table of Contents
published in 2014 require companies to obtain permits issued at six-month intervals to allow exports of products, including copper concentrates.
Despite PT-FI’s rights under its COW to export concentrates without the payment of duties, PT-FI was unable to obtain administrative approval for exports and operated at approximately half of its capacity from mid-January 2014 until late-July 2014.
On July 25, 2014, PT-FI and the Indonesian government entered into a Memorandum of Understanding (MOU) under which PT-FI and the government agreed to negotiate an amended COW to address provisions related to the size of PT-FI’s concession area, royalties and taxes, domestic processing and refining, divestment, local content, and continuation of operations post-2021. Execution of the MOU enabled the resumption of concentrate exports, which began in August 2014.
Effective with the signing of the MOU, PT-FI agreed to provide a $115 million assurance bond to support its commitment for smelter development, pay higher royalties on copper, gold and silver and pay export duties set forth in a new regulation issued by the Indonesian government on July 25, 2014.
Among other items, MOU provisions to be addressed in the negotiation of an amended COW include provisions for the development of new copper smelting and refining capacity in Indonesia, which will take into consideration an equitable sharing of costs between PT-FI (and any partners in the project) and the Indonesian government through fiscal incentives and PT-FI’s requirement for assurance of fiscal and legal certainty of its operational rights, provisions for divestment to the Indonesian government and/or Indonesian nationals of up to a 30 percent interest (an additional 20.64 percent interest) in PT-FI at fair value, and continuation of operations from 2022 through 2041. The parties agreed to complete negotiations within a six month period. Under the MOU, no terms of the COW other than those relating to the export duties, smelter bond and royalties described above will be changed until the completion of the amended COW.
The MOU also provides that negotiations for an amended COW will take into consideration PT-FI’s need for assurance of legal and fiscal terms post-2021 for PT-FI to continue with its large-scale investment program for the development of its underground reserves.
The revisions to the COW are expected to result in additional costs for our Indonesian operations. We cannot predict whether we will be successful in reaching a satisfactory agreement on the terms of our long-term mining rights. If we are unable to reach agreement with the government on our long-term rights, we may be required to reduce or defer investments in our underground development projects, which would negatively impact future production and reserves. In addition, we are required to apply for renewal of export permits at six-month intervals and cannot predict if such permits will be granted on a timely basis or whether we will be permitted to export concentrates after January 12, 2017.
On July 22, 2014, the Indonesian General Elections Commission announced that Joko “Jokowi” Widodo was elected Indonesia’s next president in the election held on July 9, 2014, to take office in October 2014 for a five-year term. PT-FI’s COW negotiations will take place during a period of transition for the Indonesian national government, and we cannot predict what impact the transition will have on the progress or outcome of the negotiations.
Except as described above, there have been no material changes to our risk factors during the three-month period ended June 30, 2014. 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, 2013.
