FCX subsidiaries that operate in the U.S. also are subject to potential liabilities arising under CERCLA and similar state laws that impose responsibility on current and previous owners and operators of a facility for the remediation of hazardous substances released from the facility into the environment, including damages to natural resources, irrespective of when the damage to the environment occurred or who caused it. This remediation liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site selected by the transporter. This liability often is shared on a joint and several basis, meaning that each responsible party is fully responsible for the remediation, although in many cases some or all of the other historical owners or operators no longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX’s acquisition of FMC in 2007, many of the subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S., and FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and several state agencies that, under CERCLA or similar state laws and regulations, they may be liable for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD).

Since that time, environmental remediation was performed by members of the Pinal Creek Group (PCG), consisting of FMC Miami, Inc. (Miami), a wholly owned subsidiary of FMC, and two other companies. Pursuant to a 2010 settlement agreement, Miami agreed to take full responsibility for future groundwater remediation at the Pinal Creek site, with limited exceptions. Remediation work continues at this time and is expected to continue for many years in the future.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Newtown Creek.</font><font style="font-family:Arial;font-size:10pt;"> From the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of FMC, operated a smelter, and from the 1930s until 1984, it operated a refinery on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms part of the boundary between Brooklyn and Queens in New York City. Heavy industrialization along the banks of the creek and discharges from the City of New York’s sewer system over more than a century resulted in significant environmental contamination of the waterway. In 2010, EPA notified PDRC and five others that EPA considers them to be PRPs under CERCLA. The notified parties began working with EPA to identify other PRPs, and EPA proposed that the notified parties perform a Remedial Investigation/Feasibility Study (RI/FS) at their expense and reimburse EPA for its oversight costs. EPA is not expected to propose a remedy until after a RI/FS is completed. Additionally, in 2010, EPA designated the creek as a Superfund site, and in 2011, PDRC and five other parties entered an Administrative Order on Consent (AOC) to perform a RI/FS to assess the nature and extent of environmental contamination in the creek and identify potential remedial options. The parties</font><font style="font-family:inherit;font-size:10pt;">'</font><font style="font-family:Arial;font-size:10pt;"> RI/FS work under the AOC and their identification of other PRPs are ongoing and expected to take several years to complete. The actual costs of fulfilling this remedial obligation and the allocation of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remediation remedy ultimately selected by EPA and related allocation determinations. Depending on the overall cost and the portion allocated to PDRC, that share could be material to FCX.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Historical Smelter Sites</font><font style="font-family:Arial;font-size:10pt;">. FMC and its predecessors at various times owned or operated copper and zinc smelters in states including Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania. For some of these smelter sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating and, if appropriate, remediating environmental conditions associated with the smelters. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate site conditions associated with the smelters. The historical smelter sites are in various stages of assessment and remediation. FCX has been in the past and may again in the future be subject to litigation brought by private parties, regulators and local governmental authorities related to these historical smelter sites.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Uranium Mining Sites.</font><font style="font-family:Arial;font-size:10pt;"> During a period between 1940 and the early 1970s, certain FMC predecessor entities and/or subsidiaries were involved in uranium exploration and mining in the western U.S., primarily on federal and tribal lands in the Four Corners region of the southwest. Similar exploration and mining activities by other companies have also caused environmental impacts warranting remediation, and EPA and local authorities are currently evaluating the need for significant cleanup activities in the region. To date, FMC has undertaken remediation at a limited number of sites associated with these predecessor entities. Initiatives to gather additional information about sites in the region are ongoing.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Other.</font><font style="font-family:Arial;font-size:10pt;"> In December 2013, a lawsuit was filed against FCX's subsidiary that operates the Candelaria mine in Chile by the neighboring municipality of Tierra Amarilla (</font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">Municipality of Tierra Amarilla v. Compania Contractual Minera Candelaria</font><font style="font-family:Arial;font-size:10pt;">, Second Environmental Court, Santiago, Chile, filed December 12, 2013). The complaint, which as of February 21, 2014, had not been served, was filed in a recently established environmental court and alleges extensive environmental harm, including alleged contamination of soils, air, surface water and groundwater, and depletion of water supplies, in addition to allegations regarding climate damage, traffic, dust, noise and nuisance associated with blastings. The complaint seeks broad relief that if granted could require FCX to cease some or all of its operations at Candelaria and nearby facilities and restore the environment to its original condition. Because of the early stage of the proceedings, FCX is currently unable to estimate the possible loss or range of loss, if any, that could result from this matter. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-weight:bold;">Asset Retirement Obligations (AROs).</font><font style="font-family:Arial;font-size:10pt;"> FCX’s ARO estimates are reflected on a third-party cost basis and comply with FCX’s legal obligation to retire tangible, long-lived assets.

FCX has satisfied financial assurance requirements by using a variety of mechanisms, primarily involving parent company performance guarantees and financial capability demonstrations, but also including trust funds, surety bonds, letters of credit and collateral. The applicable regulations specify financial strength tests that are designed to confirm a company’s or guarantor’s financial capability to fund estimated reclamation and closure costs. The amount of financial assurance FCX is required to provide will vary with changes in laws, regulations, reclamation and closure requirements, and cost estimates.

The New Mexico Environment Department (NMED) has required each of these operations to submit closure plans for NMED’s approval. The closure plans must include measures to assure meeting groundwater quality standards following the closure of discharging facilities and to abate any groundwater or surface water contamination. In 2013, the WQCC adopted Supplemental Permitting Requirements for Copper Mining Facilities, which became effective on October 31, 2013. These rules identify closure requirements for copper mine facilities. The rules were adopted after an extensive stakeholder process in which FCX participated and were jointly supported by FCX and NMED. Although the rules are being challenged in the New Mexico courts by certain environmental organizations and the New Mexico Attorney General, their adoption, along with other commitments in a settlement agreement between NMED and FCX, have allowed NMED and FCX</font><font style="font-family:inherit;font-size:10pt;">’</font><font style="font-family:Arial;font-size:10pt;">s Tyrone operation to dismiss its appeal of a WQCC Final Order, dated February 4, 2009, regarding closure conditions applicable to the Tyrone mine.

On October 17, 2013, the Arizona Superior Court extended the permanent stay of the Arizona actions until March 31, 2014. The actions name some or all of the following as defendants: the directors and certain officers of FCX, two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions allege, among other things, that the FCX directors breached their fiduciary duties to FCX stockholders because they, among other things, pursued their own interests at the expense of stockholders in approving the PXP and MMR mergers. The complaints also allege that some or all of the following parties aided and abetted the wrongful acts allegedly committed by the directors and certain officers of FCX: two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions seek as relief, among other things, an injunction barring or rescinding both the PXP merger and the MMR merger and requiring submission of the proposed PXP merger and MMR merger to a vote of FCX stockholders, damages, and attorneys' fees and costs. On October 10, 2013, FCX and the other defendants filed a motion to dismiss the second amended consolidated complaint that was filed by plaintiffs on July 19, 2013.

On October 16, 2013, the court entered an order approving the settlement, the terms of which were not material to FCX.

On April 19, 2013, the Louisiana Civil District Court granted defendants' motion to stay the action pending the resolution of the consolidated action brought by MMR stockholders in the Delaware Court of Chancery. As a result of the settlement of the consolidated Delaware action, the Louisiana action will be dismissed. Each of the actions names some or all of the following as defendants, in addition to MMR and its directors: FCX, two FCX subsidiaries, the Gulf Coast Ultra Deep Royalty Trust and PXP. The actions alleged that MMR's directors breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with respect to the merger, and that PXP, FCX, or both, aided and abetted the breach of fiduciary duty by MMR's directors. The Delaware action also asserted claims derivatively on behalf of MMR. The actions sought, among other things, injunctive relief barring or rescinding the MMR merger, damages, and attorneys' fees and costs. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Kay County Litigation. </font><font style="font-family:Arial;font-size:10pt;">On May 23, 2012, the Board of Commissioners of Kay County, Oklahoma, filed suit in Oklahoma District Court against FCX and several affiliates, including Blackwell Zinc Company, Inc.

These assessments cover the period October 2006 to December 2007 and the years 2008 and 2009. In July 2013, the Peruvian Tax Tribunal issued two decisions affirming SUNAT's assessments for the period October 2006 through December 2008. Decisions by the Tax Tribunal end the administrative stage of the appeal procedures for the assessments. In September 2013, Cerro Verde filed judiciary appeals related to the assessments because it continues to believe that its 1998 stability agreement exempts all minerals extracted from its mining concession from royalties, irrespective of the method used for processing those minerals. Although FCX believes its interpretation of the stability agreement is correct, if Cerro Verde is ultimately found responsible for these assessments, it may also be liable for penalties and interest, which accrues at rates that range from approximately </font><font style="font-family:Arial;font-size:10pt;">7 percent</font><font style="font-family:Arial;font-size:10pt;"> to </font><font style="font-family:Arial;font-size:10pt;">18 percent</font><font style="font-family:Arial;font-size:10pt;"> based on the year accrued and the currency in which the amounts would be payable. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">On October 1, 2013, SUNAT served Cerro Verde with a demand for payment totaling </font><font style="font-family:Arial;font-size:10pt;">492 million</font><font style="font-family:Arial;font-size:10pt;"> Peruvian nuevo soles (</font><font style="font-family:Arial;font-size:10pt;">$176 million</font><font style="font-family:Arial;font-size:10pt;"> based on exchange rates as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2013</font><font style="font-family:Arial;font-size:10pt;">, including interest and penalties of </font><font style="font-family:Arial;font-size:10pt;">$104 million</font><font style="font-family:Arial;font-size:10pt;">, or a total of </font><font style="font-family:Arial;font-size:10pt;">$94 million</font><font style="font-family:Arial;font-size:10pt;"> net of noncontrolling interests) based on the Peruvian Tax Tribunal’s July 2013 decisions for the period October 2006 through December 2008. As permitted by law, Cerro Verde requested and was granted an installment payment program that defers payment for six months and thereafter satisfies the amount via sixty-six equal monthly payments. On July 19, 2013, a hearing on SUNAT's assessment for 2009 was held, but no decision has been issued by the Tax Tribunal for that year.

style="font-family:Arial;font-size:10pt;">, because Cerro Verde believes its 1998 stability agreement exempts it from these royalties and believes any payments will be recoverable.</font></div><div

The amount of such taxes and related penalties under this view would be significant. PT-FI believes that, pursuant to the terms of its Contract of Work, it is only required to pay value added taxes on these types of goods imported after December 30, 2009.

FCX subsidiaries that operate in the U.S. also are subject to potential liabilities arising under CERCLA and similar state laws that impose responsibility on current and previous owners and operators of a facility for the remediation of hazardous substances released from the facility into the environment, including damages to natural resources, irrespective of when the damage to the environment occurred or who caused it. This remediation liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site selected by the transporter. This liability often is shared on a joint and several basis, meaning that each responsible party is fully responsible for the remediation, although in many cases some or all of the other historical owners or operators no longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX’s acquisition of FMC in 2007, many of the subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S., and FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and several state agencies that, under CERCLA or similar state laws and regulations, they may be liable for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD).

Since that time, environmental remediation was performed by members of the Pinal Creek Group (PCG), consisting of FMC Miami, Inc. (Miami), a wholly owned subsidiary of FMC, and two other companies. Pursuant to a 2010 settlement agreement, Miami agreed to take full responsibility for future groundwater remediation at the Pinal Creek site, with limited exceptions. Remediation work continues at this time and is expected to continue for many years in the future.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Newtown Creek.</font><font style="font-family:Arial;font-size:10pt;"> From the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of FMC, operated a smelter, and from the 1930s until 1984, it operated a refinery on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms part of the boundary between Brooklyn and Queens in New York City. Heavy industrialization along the banks of the creek and discharges from the City of New York’s sewer system over more than a century resulted in significant environmental contamination of the waterway. In 2010, EPA notified PDRC and five others that EPA considers them to be PRPs under CERCLA. The notified parties began working with EPA to identify other PRPs, and EPA proposed that the notified parties perform a Remedial Investigation/Feasibility Study (RI/FS) at their expense and reimburse EPA for its oversight costs. EPA is not expected to propose a remedy until after a RI/FS is completed. Additionally, in 2010, EPA designated the creek as a Superfund site, and in 2011, PDRC and five other parties entered an Administrative Order on Consent (AOC) to perform a RI/FS to assess the nature and extent of environmental contamination in the creek and identify potential remedial options. The parties</font><font style="font-family:inherit;font-size:10pt;">'</font><font style="font-family:Arial;font-size:10pt;"> RI/FS work under the AOC and their identification of other PRPs are ongoing and expected to take several years to complete. The actual costs of fulfilling this remedial obligation and the allocation of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remediation remedy ultimately selected by EPA and related allocation determinations. Depending on the overall cost and the portion allocated to PDRC, that share could be material to FCX.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Historical Smelter Sites</font><font style="font-family:Arial;font-size:10pt;">. FMC and its predecessors at various times owned or operated copper and zinc smelters in states including Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania. For some of these smelter sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating and, if appropriate, remediating environmental conditions associated with the smelters. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate site conditions associated with the smelters. The historical smelter sites are in various stages of assessment and remediation. FCX has been in the past and may again in the future be subject to litigation brought by private parties, regulators and local governmental authorities related to these historical smelter sites.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Uranium Mining Sites.</font><font style="font-family:Arial;font-size:10pt;"> During a period between 1940 and the early 1970s, certain FMC predecessor entities and/or subsidiaries were involved in uranium exploration and mining in the western U.S., primarily on federal and tribal lands in the Four Corners region of the southwest. Similar exploration and mining activities by other companies have also caused environmental impacts warranting remediation, and EPA and local authorities are currently evaluating the need for significant cleanup activities in the region. To date, FMC has undertaken remediation at a limited number of sites associated with these predecessor entities.

The complaint, which as of February 21, 2014, had not been served, was filed in a recently established environmental court and alleges extensive environmental harm, including alleged contamination of soils, air, surface water and groundwater, and depletion of water supplies, in addition to allegations regarding climate damage, traffic, dust, noise and nuisance associated with blastings. The complaint seeks broad relief that if granted could require FCX to cease some or all of its operations at Candelaria and nearby facilities and restore the environment to its original condition. Because of the early stage of the proceedings, FCX is currently unable to estimate the possible loss or range of loss, if any, that could result from this matter. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-weight:bold;">Asset Retirement Obligations (AROs).</font><font style="font-family:Arial;font-size:10pt;"> FCX’s ARO estimates are reflected on a third-party cost basis and comply with FCX’s legal obligation to retire tangible, long-lived assets.

Refer to Note 1 for further discussion of FCX's accounting policy for litigation contingencies.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Asbestos Claims.</font><font style="font-family:Arial;font-size:10pt;font-weight:bold;"> </font><font style="font-family:Arial;font-size:10pt;">Since approximately 1990, FMC and various subsidiaries have been named as defendants in a large number of lawsuits that claim personal injury either from exposure to asbestos allegedly contained in electrical wire products produced or marketed many years ago or from asbestos contained in buildings and facilities located at properties owned or operated by FMC affiliates, or from alleged asbestos in talc products. Many of these suits involve a large number of codefendants. Based on litigation results to date and facts currently known, FCX believes there is a reasonable possibility that losses may have been incurred related to these matters; however, FCX also believes that the amounts of any such losses, individually or in the aggregate, are not material to its consolidated financial statements. There can be no assurance, however, that future developments will not alter this conclusion.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Shareholder Litigation</font><font style="font-family:Arial;font-size:10pt;">. Fourteen derivative actions challenging the PXP merger and/or the MMR merger were filed on behalf of FCX by purported FCX stockholders. Ten were filed in the Court of Chancery of the State of Delaware and three were filed in the Superior Court of the State of Arizona, County of Maricopa. On January 25, 2013, the Delaware Court of Chancery consolidated the Delaware actions into a single action, </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">In Re Freeport-McMoRan Copper & Gold Inc. Derivative Litigation</font><font style="font-family:Arial;font-size:10pt;">, No. 8145-VCN. On March 5, 2013, an additional complaint was filed in the Delaware Court of Chancery, </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">Stephen Blau MD Money Purchase Pension Plan Trust v. Moffett et al.</font><font style="font-family:Arial;font-size:10pt;">, No. 8389-VCN. A motion to consolidate that action with </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">In Re Freeport-McMoRan Copper & Gold Inc. Derivative Litigation</font><font style="font-family:Arial;font-size:10pt;"> is pending. On January 17, 2013, the Arizona Superior Court consolidated two of the Arizona actions into </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">In Re Freeport-McMoRan Derivative Litigation</font><font style="font-family:Arial;font-size:10pt;">, No. CV2012-018351. A third Arizona complaint, </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">Harris v. Adkerson et al.</font><font style="font-family:Arial;font-size:10pt;">, No. CV2013-004163, was consolidated with the first two Arizona actions on February 8, 2013. On March 18, 2013, the Delaware Court of Chancery granted the stipulation made by the parties to allow the plaintiffs in </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">In Re Freeport-McMoRan Derivative Litigation</font><font style="font-family:Arial;font-size:10pt;">, No. CV2012-01835, to intervene in the consolidated Delaware action. On October 17, 2013, the Arizona Superior Court extended the permanent stay of the Arizona actions until March 31, 2014. The actions name some or all of the following as defendants: the directors and certain officers of FCX, two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions allege, among other things, that the FCX directors breached their fiduciary duties to FCX stockholders because they, among other things, pursued their own interests at the expense of stockholders in approving the PXP and MMR mergers. The complaints also allege that some or all of the following parties aided and abetted the wrongful acts allegedly committed by the directors and certain officers of FCX: two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions seek as relief, among other things, an injunction barring or rescinding both the PXP merger and the MMR merger and requiring submission of the proposed PXP merger and MMR merger to a vote of FCX stockholders, damages, and attorneys' fees and costs. On October 10, 2013, FCX and the other defendants filed a motion to dismiss the second amended consolidated complaint that was filed by plaintiffs on July 19, 2013. Oral argument on the motion to dismiss is scheduled in the Delaware Chancery Court on March 12, 2014. FCX intends to vigorously defend itself in these matters.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">Ten putative class actions challenging the MMR merger were filed on behalf of MMR stockholders. Nine were filed in the Court of Chancery of the State of Delaware. On January 25, 2013, the Court of Chancery consolidated the actions into a single action, </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">In Re McMoRan Exploration Co. Stockholder Litigation</font><font style="font-family:Arial;font-size:10pt;">, No. 8132-VCN. On June 28, 2013, the parties entered into a settlement agreement, and on October 11, 2013, the court held a hearing to consider the evidence in support of the proposed settlement. On October 16, 2013, the court entered an order approving the settlement, the terms of which were not material to FCX. One action was also filed in the Civil District Court for the Parish of Orleans of the State of Louisiana: </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">Langley v. Moffett et al.</font><font style="font-family:Arial;font-size:10pt;">, No. 2012-11904, filed December 19, 2012. On April 19, 2013, the Louisiana Civil District Court granted defendants' motion to stay the action pending the resolution of the consolidated action brought by MMR stockholders in the Delaware Court of Chancery. As a result of the settlement of the consolidated Delaware action, the Louisiana action will be dismissed. Each of the actions names some or all of the following as defendants, in addition to MMR and its directors: FCX, two FCX subsidiaries, the Gulf Coast Ultra Deep Royalty Trust and PXP. The actions alleged that MMR's directors breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with respect to the merger, and that PXP, FCX, or both, aided and abetted the breach of fiduciary duty by MMR's directors. The Delaware action also asserted claims derivatively on behalf of MMR. The actions sought, among other things, injunctive relief barring or rescinding the MMR merger, damages, and attorneys' fees and costs. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Kay County Litigation. </font><font style="font-family:Arial;font-size:10pt;">On May 23, 2012, the Board of Commissioners of Kay County, Oklahoma, filed suit in Oklahoma District Court against FCX and several affiliates, including Blackwell Zinc Company, Inc. (BZC), an indirect subsidiary of FCX that owned and operated a zinc smelter in Blackwell, Oklahoma, from 1916 to 1974, entitled </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">Board of Commissioners of the County of Kay, Oklahoma v. Freeport-McMoRan Copper & Gold Inc., et al.</font><font style="font-family:Arial;font-size:10pt;">, United States District Court, Western District of Oklahoma, Case No. 5:12-cv-00601-C. The suit alleged that BZC permitted large quantities of smelter waste to be used as road building and fill material throughout Kay County over a period of decades and sought unspecified financial assistance for removing or covering much of the material and unspecified damages for the alleged public nuisance created by the presence of the material. On November 25, 2013, the case was settled for an amount that is not material to FCX. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-weight:bold;">Tax and Other Matters. </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Cerro Verde Royalty Dispute.</font><font style="font-family:Arial;font-size:10pt;"> SUNAT, the Peruvian national tax authority, has assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006. These assessments cover the period October 2006 to December 2007 and the years 2008 and 2009. In July 2013, the Peruvian Tax Tribunal issued two decisions affirming SUNAT's assessments for the period October 2006 through December 2008. Decisions by the Tax Tribunal end the administrative stage of the appeal procedures for the assessments. In September 2013, Cerro Verde filed judiciary appeals related to the assessments because it continues to believe that its 1998 stability agreement exempts all minerals extracted from its mining concession from royalties, irrespective of the method used for processing those minerals. Although FCX believes its interpretation of the stability agreement is correct, if Cerro Verde is ultimately found responsible for these assessments, it may also be liable for penalties and interest, which accrues at rates that range from approximately </font><font style="font-family:Arial;font-size:10pt;">7 percent</font><font style="font-family:Arial;font-size:10pt;"> to </font><font style="font-family:Arial;font-size:10pt;">18 percent</font><font style="font-family:Arial;font-size:10pt;"> based on the year accrued and the currency in which the amounts would be payable. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">On October 1, 2013, SUNAT served Cerro Verde with a demand for payment totaling </font><font style="font-family:Arial;font-size:10pt;">492 million</font><font style="font-family:Arial;font-size:10pt;"> Peruvian nuevo soles (</font><font style="font-family:Arial;font-size:10pt;">$176 million</font><font style="font-family:Arial;font-size:10pt;"> based on exchange rates as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2013</font><font style="font-family:Arial;font-size:10pt;">, including interest and penalties of </font><font style="font-family:Arial;font-size:10pt;">$104 million</font><font style="font-family:Arial;font-size:10pt;">, or a total of </font><font style="font-family:Arial;font-size:10pt;">$94 million</font><font style="font-family:Arial;font-size:10pt;"> net of noncontrolling interests) based on the Peruvian Tax Tribunal’s July 2013 decisions for the period October 2006 through December 2008. As permitted by law, Cerro Verde requested and was granted an installment payment program that defers payment for six months and thereafter satisfies the amount via sixty-six equal monthly payments. On July 19, 2013, a hearing on SUNAT's assessment for 2009 was held, but no decision has been issued by the Tax Tribunal for that year. As of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2013</font><font style="font-family:Arial;font-size:10pt;">, the aggregate amount of the assessments, including interest and penalties, for the year 2009 was </font><font style="font-family:Arial;font-size:10pt;">206 million</font><font style="font-family:Arial;font-size:10pt;"> Peruvian nuevo soles (</font><font style="font-family:Arial;font-size:10pt;">$74 million</font><font style="font-family:Arial;font-size:10pt;"> based on exchange rates as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2013</font><font style="font-family:Arial;font-size:10pt;">, or a total of </font><font style="font-family:Arial;font-size:10pt;">$39 million</font><font style="font-family:Arial;font-size:10pt;"> net of noncontrolling interests). SUNAT may make additional assessments for mining royalties and associated penalties and interest for the years 2010 through 2013, which Cerro Verde will contest; FCX believes any such assessments for the years 2010 through 2013, if made, would in the aggregate be similar to the aggregate assessments received for the periods October 2006 through December 2009. No amounts were accrued for these assessments or the installment payment program as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2013</font><font style="font-family:Arial;font-size:10pt;">, because Cerro Verde believes its 1998 stability agreement exempts it from these royalties and believes any payments will be recoverable.</font></div><div
