OPERATIONS
Consolidated. First-quarter 2013 consolidated copper sales of 954 million pounds were higher than the January 2013 estimate of 940 million pounds (primarily reflecting higher production and sales from Africa) and also higher than first-quarter 2012 sales of 827 million pounds primarily because of higher production from Indonesia and Africa.
First-quarter 2013 consolidated gold sales of 214 thousand ounces were lower than the January 2013 estimate of 230 thousand ounces (primarily reflecting timing of shipments) and lower than first-quarter 2012 sales of 288 thousand ounces primarily because of anticipated lower ore grades in Indonesia.
First-quarter 2013 consolidated molybdenum sales of 25 million pounds were higher than the January 2013 estimate of 23 million pounds and first-quarter 2012 sales of 21 million pounds primarily because of stronger sales in the metallurgical and chemical sectors.
Consolidated sales from mines for the year 2013 are expected to approximate 4.3 billion pounds of copper, 1.4 million ounces of gold and 92 million pounds of molybdenum, including 1.0 billion pounds of copper, 295 thousand ounces of gold and 23 million pounds of molybdenum for second-quarter 2013.
As anticipated, consolidated average unit net cash costs (net of by-product credits) of $1.57 per pound of copper in first-quarter 2013 were higher than unit net cash costs of $1.26 per pound in first-quarter 2012 reflecting lower by-product credits.
Assuming average prices of $1,400 per ounce of gold and $11 per pound of molybdenum for the remainder of 2013 and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for FCX's copper mining operations are expected to average approximately $1.45 per pound of copper for the year 2013. Projected unit net cash costs for 2013 are higher than previous estimates primarily because of lower gold credits. The impact of price changes for the remainder of 2013 on consolidated unit net cash costs would approximate $0.015 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. Quarterly unit net cash costs vary with fluctuations in sales volumes and average realized prices (primarily gold and molybdenum prices), and are expected to decline during the second half of the year as FCX gains access to higher grade ore in Indonesia (54 percent of 2013 consolidated copper sales volumes and 63 percent of consolidated gold sales volumes are expected in the second half of 2013).
North America Copper Mines. FCX operates seven open-pit copper mines in North America - Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. All of the North America mining operations are wholly owned, except for Morenci. FCX records its 85 percent joint venture interest in Morenci using the proportionate consolidation method. In addition to copper, certain of FCX's North America copper mines (Sierrita, Bagdad, Morenci and Chino) also produce molybdenum concentrates, which are sold to FCX's molybdenum sales company at market-based pricing.
Operating and Development Activities. FCX has increased production from its North America copper mines in recent years and continues to evaluate a number of opportunities to invest in additional production capacity at several of its North America copper mines in response to positive exploration results in recent years.
At Morenci, FCX is expanding mining and milling capacity to process additional sulfide ores identified through exploratory drilling. The approximate $1.4 billion project is targeting incremental annual production of approximately 225 million pounds of copper in 2014 (an approximate 40 percent increase from 2012) through an

Freeport-McMoRan Copper & Gold 3

increase in milling rates from 50,000 metric tons of ore per day to approximately 115,000 metric tons of ore per day and mining rates from 700,000 short tons per day to 900,000 short tons per day. The targeted increase in mining rates has been achieved, engineering activities are nearing completion and construction activities for the new mill and related facilities are in progress.

Consolidated copper sales volumes from North America of 353 million pounds in first-quarter 2013 were higher than first-quarter 2012 sales of 338 million pounds primarily reflecting increased production at the Chino mine.
FCX expects sales from the North America copper mines to approximate 1.45 billion pounds of copper for the year 2013, compared with 1.35 billion pounds in 2012, primarily reflecting higher production at Morenci and Chino.
Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.86 per pound of copper in first-quarter 2013 were higher than unit net cash costs of $1.51 per pound in first-quarter 2012 primarily reflecting higher mining rates and lower molybdenum credits.
FCX estimates that average unit net cash costs (net of by-product credits) for the North America copper mines would approximate $1.89 per pound of copper for the year 2013, based on current sales volume and cost estimates and assuming an average molybdenum price of $11 per pound for the remainder of 2013. North America's average projected unit net cash costs would change by approximately $0.025 per pound for each $2 per pound change in the average price of molybdenum for the remainder of 2013.
South America Mining. FCX operates four copper mines in South America - Cerro Verde in Peru and El Abra, Candelaria and Ojos del Salado in Chile. FCX owns a 53.56 percent interest in Cerro Verde, a 51 percent interest in El Abra, and an 80 percent interest in both the Candelaria and Ojos del Salado mining complexes. All operations in South America are consolidated in FCX's financial statements. South America mining includes open-pit and underground mining. In addition to copper, the Candelaria and Ojos del Salado mines produce gold and silver, and the Cerro Verde mine produces molybdenum concentrates that are sold to FCX's molybdenum sales company at market-based pricing.

Freeport-McMoRan Copper & Gold 4

Operating and Development Activities. FCX has commenced initial construction activities associated with a large-scale expansion at Cerro Verde. The project, with an estimated cost of $4.4 billion, 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.
FCX continues to engage in studies to evaluate a potential large-scale milling operation at El Abra to process additional sulfide material and to achieve higher recoveries. Exploration results at El Abra indicate the potential for a significant sulfide resource.

Consolidated copper sales volumes from South America of 285 million pounds in first-quarter 2013 approximated first-quarter 2012 sales of 286 million pounds as higher grade ore at Candelaria offset lower grade ore at Cerro Verde.
FCX expects South America's sales to approximate 1.34 billion pounds of copper for the year 2013, compared with sales of 1.25 billion pounds of copper in 2012, primarily reflecting higher grade ore at Candelaria.
Average unit net cash costs (net of by-product credits) for South America of $1.51 per pound of copper in first-quarter 2013 were higher than unit net cash costs of $1.40 per pound in first-quarter 2012 primarily reflecting higher costs for maintenance and repairs.
FCX estimates that average unit net cash costs (net of by-product credits) for South America mining would approximate $1.44 per pound of copper for the year 2013, based on current sales volume and cost estimates and assuming average prices of $1,400 per ounce of gold and $11 per pound of molybdenum for the remainder of 2013.

Freeport-McMoRan Copper & Gold 5

Indonesia Mining. Through its 90.64 percent owned and wholly consolidated subsidiary PT Freeport Indonesia, FCX's assets include one of the world's largest copper and gold deposits at the Grasberg minerals district in Papua, Indonesia. PT Freeport Indonesia produces copper concentrates, which contain significant quantities of gold and silver.
Operating and Development Activities. FCX has several projects in progress in the Grasberg minerals district, primarily related to the development of large-scale, 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 currently anticipated transition from the Grasberg open pit in 2017. Development of the Grasberg Block Cave and Deep Mill Level Zone (DMLZ) is advancing according to schedule, which would enable the DMLZ to commence production in 2015 and the Grasberg Block Cave mine to commence production in 2017. Over the next five years, estimated aggregate capital spending on these projects is currently expected to average $735 million per year ($585 million per year net to PT Freeport Indonesia).

Indonesia's first-quarter 2013 copper sales of 198 million pounds were higher than first-quarter 2012 copper sales of 134 million pounds when labor-related disruptions affected operations. Productivity measures have continued to improve resulting in first-quarter 2013 daily mill throughput averaging 199,400 metric tons per day, including 59,000 metric tons per day from the Deep Ore Zone (DOZ) underground mine.
As expected, Indonesia's first-quarter 2013 gold sales of 191 thousand ounces were lower than first-quarter 2012 gold sales of 266 thousand ounces primarily as a result of lower ore grades from mine sequencing.
At the Grasberg mine, the sequencing of mining areas with varying ore grades causes fluctuations in the timing of ore production resulting in varying quarterly and annual sales of copper and gold. FCX expects sales from Indonesia to approximate 1.1 billion pounds of copper and 1.25 million ounces of gold for the year 2013, compared with 716 million pounds of copper and 915 thousand ounces of gold for the year 2012. FCX expects sales from Indonesia to increase in the second half of 2013 as PT Freeport Indonesia gains access to higher ore grades and achieves the targeted ramp up in production from the DOZ underground mine to approximately 80,000 metric tons per day (57 percent of Indonesia's projected copper sales and 63 percent of Indonesia's projected gold sales are expected in the second half of 2013).

Freeport-McMoRan Copper & Gold 6

Indonesia's unit net cash costs (including gold and silver credits) of $1.34 per pound of copper in first-quarter 2013 were higher than unit net cash costs of $0.33 per pound in first-quarter 2012 primarily reflecting lower gold credits, partly offset by higher copper sales volumes.
FCX estimates Indonesia's average unit net cash costs (net of gold and silver credits) would approximate $1.00 per pound of copper for the year 2013, based on current sales volume and cost estimates and assuming an average gold price of $1,400 per ounce for the remainder of 2013. Projected unit net cash costs for 2013 are higher than previous estimates primarily because of lower gold credits. Indonesia's projected unit net cash costs would change by approximately $0.05 per pound for each $50 per ounce change in the average price of gold for the remainder of 2013. 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 sales volumes, as well as average realized gold prices for the quarterly period. Indonesia's unit net cash costs are expected to decline during the second half of the year as it gains access to higher grade ore.
Africa Mining. Through its 56 percent owned and wholly consolidated subsidiary Tenke Fungurume Mining S.A.R.L. (TFM), FCX operates the Tenke Fungurume (Tenke) mine in the Katanga province of the Democratic Republic of Congo (DRC). In addition to copper, the Tenke mine produces cobalt hydroxide.
Operating and Development Activities. TFM has completed its second phase expansion project, which included optimizing the current plant and increasing mine, mill and processing capacity. The expanded mill is capable of throughput of 14,000 metric tons of ore per day to enable increasing copper production by 150 million pounds to over 430 million pounds per year. Costs incurred to date total approximately $615 million and included mill upgrades, additional mining equipment and a new tankhouse. A second sulphuric acid plant, which was included in the $850 million total estimated project capital cost, is expected to be installed in 2015. The expanded mill facility is performing well, with first-quarter 2013 average throughput rates of 14,600 metric tons per day.
FCX continues to engage in drilling activities, exploration analyses and metallurgical testing to evaluate the potential of the highly prospective minerals district at Tenke. These analyses are being incorporated in future plans to evaluate opportunities for expansion. Future expansions are subject to a number of factors, including economic and market conditions, and the business and investment climate in the DRC.

Freeport-McMoRan Copper & Gold 7

Africa mining operations established new records in first-quarter 2013 for mining, milling and copper sales. Copper sales from Africa of 118 million pounds in first-quarter 2013 were higher than first-quarter 2012 copper sales of 69 million pounds primarily reflecting higher mining and milling rates principally related to the ramp up of the expansion project and higher ore grades.
FCX expects Africa's sales to approximate 435 million pounds of copper and 28 million pounds of cobalt for the year 2013, compared with 336 million pounds of copper and 25 million pounds of cobalt for the year 2012.
Africa's unit net cash costs (net of cobalt credits) of $1.23 per pound of copper in first-quarter 2013 were slightly lower than unit net cash costs of $1.25 per pound in first-quarter 2012, primarily reflecting the benefit of higher sales volumes, partly offset by lower cobalt credits.
FCX estimates Africa's average unit net cash costs would approximate $1.18 per pound of copper for the year 2013, based on current sales volume and cost estimates and assuming an average cobalt price of $12 per pound for the remainder of 2013. Africa's projected unit net cash costs would change by approximately $0.065 per pound for each $2 per pound change in the average price of cobalt for the remainder of 2013.
Freeport Cobalt. On March 29, 2013, through the newly formed and wholly consolidated Freeport Cobalt joint venture, FCX acquired a large-scale cobalt chemical refinery located in Kokkola, Finland, and the related sales and marketing business. FCX is the operator of the joint venture with an effective 56 percent ownership interest. The remaining effective ownership interests are held by FCX's partners in TFM, including 24 percent by Lundin Mining Corporation and 20 percent by La Générale des Carrières et des Mines.
This acquisition enhances FCX's cobalt marketing position, product portfolio and product development capabilities, and provides direct end-market access for the cobalt hydroxide production from TFM.
Initial consideration paid was $355 million, including $34 million of acquired cash. Under the terms of the agreement, there is the potential for additional consideration of up to $110 million over a period of three years, contingent upon the achievement of revenue-based performance targets. The acquisition was funded 70 percent by FCX and 30 percent by Lundin, which amounts will be repaid prior to any shareholder distributions.
Molybdenum Mines. FCX has 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.
Operating Data. Following is summary consolidated operating data for the molybdenum mines for the first quarters of 2013 and 2012:

|  | Three Months Ended |
|  | March 31, |
|  | 2013a |  | 2012a |
Molybdenum production (millions of recoverable pounds)b |  | 12 |  |  | 9 |  |
Unit net cash cost per pound of molybdenumc |  | $ | 7.32 |  |  | $ | 6.88 |  |

a. | Reflects operating data for the Henderson and Climax mines for first-quarter 2013, and operating data only for the Henderson mine for first-quarter 2012.

b. | Refer to consolidated operating data on page 3 for FCX's consolidated molybdenum sales, which includes sales of molybdenum produced at the molybdenum mines, as well as from certain of the North and South America copper mines.

c. | For a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in FCX's consolidated financial statements, refer to the supplemental schedule, "Product Revenues and Production Costs," beginning on page VI, which is available on FCX's website, "www.fcx.com."

The Climax molybdenum mine was commissioned in second-quarter 2012 and includes a new 25,000 metric ton per day mill facility. Molybdenum production from the Climax mine totaled 5 million pounds in first-quarter 2013 and is targeted at 20 million pounds for the year 2013 (with potential to produce up to approximately 30 million pounds per year, depending on market conditions). FCX intends to operate the Climax and Henderson mines in a flexible manner to meet market requirements.

Freeport-McMoRan Copper & Gold 8

Average unit net cash costs for FCX's molybdenum mines were $7.32 per pound of molybdenum in first-quarter 2013, compared with $6.88 per pound in first-quarter 2012, reflecting higher input costs at Henderson and the addition of production from Climax.
Based on current sales volume and cost estimates, FCX expects unit net cash costs for the molybdenum mines to average approximately $7.25 per pound of molybdenum for the year 2013 (reflecting approximately $7.50 per pound for Henderson and $6.90 per pound for Climax).
EXPLORATION ACTIVITIES
FCX is actively conducting exploration activities near its existing mines with a focus on opportunities to expand reserves that will support the development of additional future production capacity in the large minerals districts where it currently operates. Exploration results indicate opportunities for significant future potential reserve additions in North and South America and in the Tenke Fungurume minerals district. The drilling data in North America continue to indicate the potential for expanded sulfide production.
Exploration spending is expected to approximate $235 million for the year 2013, compared to $251 million in 2012. Exploration activities will continue to focus primarily on the potential for future reserve additions in FCX's existing minerals districts. Approximately one-third of the 2013 budget is associated with global greenfield exploration projects.
CASH FLOWS
FCX generated operating cash flows of $831 million (net of $430 million in working capital uses and changes in other tax payments) for first-quarter 2013. Excluding results from pending acquisitions, based on current sales volume and cost estimates and assuming average prices of $3.25 per pound of copper, $1,400 per ounce of gold and $11 per pound of molybdenum for the remainder of 2013, FCX's consolidated operating cash flows are estimated to approximate $5.5 billion (including $0.4 billion in net working capital sources and changes in other tax payments) for the year 2013. The impact of price changes during the remainder of 2013 on operating cash flows would approximate $270 million for each $0.10 per pound change in the average price of copper, $50 million for each $50 per ounce change in the average price of gold and $80 million for each $2 per pound change in the average price of molybdenum.
Capital expenditures totaled $805 million for first-quarter 2013. Excluding amounts for pending acquisitions, capital expenditures are currently estimated to approximate $4.4 billion for the year 2013 (including $2.6 billion for major projects and $1.8 billion for sustaining capital). Major projects for 2013 primarily include the expansions at Cerro Verde and Morenci and underground development activities at Grasberg. FCX is also considering additional investments at several of its sites. Capital spending plans will continue to be reviewed and adjusted in response to changes in market conditions and other factors.
Other investing activities for first-quarter 2013 included $321 million (net of cash acquired) for payments by the Freeport Cobalt joint venture to fund the March 2013 acquisition of a cobalt chemical refinery.
CASH AND DEBT
Following is a summary of cash available to the parent company, net of noncontrolling interests' share, taxes and other costs at March 31, 2013 (in billions):

a. Includes net proceeds from the March 2013 sale of $6.5 billion of senior notes that will be used to fund a portion of the pending acquisitions of PXP and MMR.

Freeport-McMoRan Copper & Gold 9

At March 31, 2013, FCX had $10.1 billion in debt, including the March 2013 issuance of $6.5 billion of senior notes.
During first-quarter 2013, FCX sold $6.5 billion of senior notes in four tranches and also entered into an agreement for a $4.0 billion bank term loan (the Term Loan). No amounts are currently available to FCX under the Term Loan, which will be funded at closing of the PXP and MMR acquisitions. The weighted-average interest rate of these financings approximates 3.1 percent. FCX expects to use the net proceeds from these financings to fund the pending acquisitions of PXP and MMR, including for the payment of cash consideration for the acquisitions and the repayment of certain indebtedness of PXP and MMR. If the PXP acquisition is not completed, FCX will be required to redeem all the outstanding 7-year, 10-year and 30-year notes (which total $5 billion) at 101 percent plus accrued and unpaid interest.
At March 31, 2013, FCX had no borrowings and $43 million of letters of credit issued under its revolving credit facility, resulting in availability of $1.5 billion. In February 2013, FCX entered into a new $3.0 billion senior unsecured revolving credit facility, which will refinance and replace its existing revolving credit facility upon completion of the pending acquisition of PXP.
FINANCIAL POLICY
FCX has a long-standing tradition of seeking to build shareholder value through investing in projects with attractive rates of return and returning cash to shareholders through common stock dividends and share purchases. FCX paid common stock dividends of $297 million in first-quarter 2013. FCX's current annual dividend rate for its common stock is $1.25 per share. On March 27, 2013, FCX's Board of Directors (the Board) declared a regular quarterly dividend of $0.3125 per share, which will be paid on May 1, 2013. FCX intends to continue to maintain a strong financial position, invest aggressively in attractive growth projects and provide cash returns to shareholders. The Board will continue to review FCX's financial policy on an ongoing basis.
PENDING ACQUISITIONS OF PXP AND MMR
On December 5, 2012, FCX announced definitive agreements to acquire, in separate transactions, PXP and MMR. PXP per-share consideration is equivalent to 0.6531 shares of FCX common stock and $25 in cash. MMR per-share consideration consists of $14.75 in cash and 1.15 units of a royalty trust, which will hold a five percent overriding royalty interest in future production of MMR's existing shallow water ultra-deep prospects. The combined company would be a premier U.S.-based natural resource company with a growing production profile and an industry leading global portfolio of mineral assets and significant oil and gas resources. The addition of a high quality, North America-focused oil and gas resource base is expected to provide strong current cash flows and significant growth potential, enhanced geographic diversification and complementary exposure to markets positioned for global growth.
Completion of each transaction is subject to receipt of PXP and MMR stockholder approval of their respective transaction. The PXP transaction is not conditioned on the closing of the MMR transaction, and the MMR transaction is not conditioned on the closing of the PXP transaction. The transactions are expected to close in second-quarter 2013, subject to satisfaction of all conditions to closing.

b. | Includes charges of $14 million ($10 million to net income attributable to common stock) for costs associated with the pending acquisitions of PXP and MMR and for the March 2013 cobalt chemical refinery acquisition.

c. | Consolidated interest expense, excluding capitalized interest, totaled $75 million in first-quarter 2013 and $99 million in first-quarter 2012. Lower interest expense in first-quarter 2013 primarily reflected the impact of the February 2012 refinancing transaction, partly offset by $17 million of additional interest expense in first-quarter 2013 related to the March 2013 sale of $6.5 billion of senior notes.

d. | FCX defers recognizing profits on intercompany sales until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net additions (reductions) to net income attributable to common stock of $25 million in first-quarter 2013 and $(32) million in first-quarter 2012. For further discussion refer to the supplemental schedule, "Deferred Profits" on page XVII.

PRODUCT REVENUES AND PRODUCTION COSTS
PRODUCT REVENUES AND UNIT NET CASH COSTS
Unit net cash costs per pound of copper and molybdenum are measures intended to provide investors with information about the cash-generating capacity of FCX's mining operations expressed on a basis relating to the primary metal product for the respective operations. FCX uses this measure for the same purpose and for monitoring operating performance by its mining operations. This information differs from measures of performance determined in accordance with U.S. generally accepted accounting principles (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 FCX's measures may not be comparable to similarly titled measures reported by other companies.
FCX presents gross profit per pound of copper in the following tables using both a “by-product” method and a “co-product” method. FCX uses the by-product method in its presentation of gross profit per pound of copper because (i) the majority of its revenues are copper revenues, (ii) it mines ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of FCX's costs to revenues from the copper, gold, molybdenum and other metals it produces, (iv) it is the method used to compare mining operations in certain industry publications and (v) it is the method used by FCX's management and Board of Directors to monitor operations. In the co-product method presentations, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent FCX's metals sales volumes and realized prices change.
FCX shows revenue adjustments for prior period open sales as separate line items. Because these adjustments do not result from current period sales, FCX has 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. Following are presentations under both the by-product and co-product methods together with reconciliations to amounts reported in FCX's consolidated financial statements.

PROVISION FOR INCOME TAXES
Following are summaries of the approximate amounts in the calculation of FCX's consolidated provision for income taxes for the first quarters of 2013 and 2012 (in millions, except percentages):

| Three Months Ended March 31, |

Consolidated FCX | $ | 1,250 |  |  | 34% | c | $ | (428 | ) |  | $ | 1,490 |  |  | 33% |  | $ | (491 | ) |

a. | Represents income by geographic location before income taxes and equity in affiliated companies' net earnings.

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

c. | FCX's consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which it operates. Accordingly, variations in the relative proportions of jurisdictional income result in fluctuations to FCX's consolidated effective income tax rate. Assuming average prices of $3.25 per pound for copper, $1,400 per ounce for gold and $11 per pound for molybdenum for the remainder of 2013 and achievement of current sales volume and cost estimates, FCX estimates its annual consolidated effective tax rate for the year 2013 (excluding impacts from the pending acquisitions of PXP and MMR) will approximate 34 percent to 35 percent.

PROVISIONAL PRICING
For first-quarter 2013, 46 percent of FCX's mined copper was sold in concentrate, 28 percent as cathode and 26 percent as rod from North America operations. Under the long-established structure of sales agreements prevalent in the industry, copper contained in concentrates and cathodes is provisionally priced at the time of shipment. The provisional prices are finalized in a contractually specified future month (generally one to four months from the shipment date) primarily based on quoted monthly average spot copper prices on the London Metal Exchange (LME). Because a significant portion of FCX's copper concentrate and cathode sales in any quarterly period usually remain subject to final pricing, the quarter-end forward price is a major determinant of recorded revenues and the average recorded copper price for the period. LME spot copper prices averaged $3.60 per pound during first-quarter 2013, compared to FCX's average realized price of $3.51 per pound.
Following are the (unfavorable) favorable impacts of net adjustments to the prior years' provisionally priced copper sales for the first quarters of 2013 and 2012 (in millions, except per share amounts):

| Three Months Ended
| March 31,
| 2013 |  | 2012
Revenues | $ | (11 | ) |  | $ | 109 |
Net income attributable to FCX common stock | $ | (5 | ) |  | $ | 47 |
Net income per share of FCX common stock | $ | (0.01 | ) |  | $ | 0.05 |

At March 31, 2013, FCX had provisionally priced copper sales at its copper mining operations, primarily South America and Indonesia, totaling 340 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $3.41 per pound, subject to final pricing over the next several months. FCX estimates that each $0.05 change in the price realized from the March 31, 2013, provisional price recorded would have an approximate $23 million effect on its 2013 consolidated revenues ($12 million to net income attributable to common stock). The LME spot copper price closed at $3.21 per pound on April 17, 2013.

FREEPORT-McMoRan COPPER & GOLD INC.
DEFERRED PROFITS
FCX defers recognizing profits on sales from its mining operations to Atlantic Copper and on 25 percent of Indonesia mining's sales to PT Smelting (PT Freeport Indonesia's 25 percent-owned Indonesian smelting unit) until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net additions (reductions) to net income attributable to common stock totaling $25 million ($0.03 per share) in first-quarter 2013 and $(32) million ($(0.03) per share) in first-quarter 2012. FCX's net deferred profits on its inventories at Atlantic Copper and PT Smelting to be recognized in future periods' net income attributable to common stock totaled $85 million at March 31, 2013. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in FCX's net deferred profits and quarterly earnings.
BUSINESS SEGMENTS
FCX has organized its operations into five primary divisions - North America copper mines, South America mining, Indonesia mining, Africa mining and Molybdenum mines. Notwithstanding this structure, FCX internally reports information on a mine-by-mine basis. Therefore, FCX concluded that its operating segments include individual mines or operations. Operating segments that meet certain thresholds are reportable segments, which are separately disclosed in the following table.
Intersegment Sales. Intersegment sales between FCX's 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.
Allocations. FCX allocates certain operating costs, expenses and capital expenditures to the operating divisions and individual segments. However, not all costs and expenses applicable to a mine or operation are allocated. All 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. In addition, most exploration and research activities are managed at the corporate level, and those costs along with some selling, general and administrative costs are not allocated to the operating divisions or 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.
