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, in some cases irrespective of when the damage to the environment occurred or who caused it. 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. These liabilities are often shared on a joint and several basis, meaning that each responsible party is fully responsible for the remediation, if 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 various 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) and to litigation by individuals allegedly exposed to hazardous substances.

Since that time, environmental remediation was performed by members of the Pinal Creek Group, consisting of FM Miami, Inc. (Miami), a wholly owned subsidiary of FCX, 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 mainly consisting of groundwater extraction and treatment continues and is expected to continue for many years in the future.</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;">Newtown Creek.</font><font style="font-family:Arial;font-size:10pt;"> From the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of FCX, operated a copper smelter, and from the 1930s until 1984 operated a copper 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, four other companies and the City of New York 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 the 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 the 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 efforts to identify other PRPs are ongoing. EPA recently identified eight additional parties as PRPs for the creek. The draft RI was submitted to EPA in November 2016, and the draft FS is expected to be submitted to EPA by the end of 2020. EPA’s remedial decision could be made in 2021 and remedial design could begin in 2022, with the actual remediation construction starting several years later. 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. The overall cost and the portion ultimately allocated to PDRC could be material to FCX. During 2017, FCX recorded charges of </font><font style="font-family:Arial;font-size:10pt;">$138 million</font><font style="font-family:Arial;font-size:10pt;"> for revised cost estimates for the Newtown Creek environmental obligation.</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;">. FCX subsidiaries and their predecessors at various times owned or operated copper, zinc and lead smelters or refineries in states including Arizona, Indiana, Kansas, Missouri, New Jersey, Oklahoma and Pennsylvania. For some of these former processing 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 these former processing facilities. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate onsite and offsite conditions associated with the facilities. The historical processing sites are in various stages of assessment and remediation. At some of these sites, disputes with local residents and elected officials regarding alleged health effects or the effectiveness of remediation efforts have resulted in litigation of various types, and similar litigation at other sites is possible. </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;">From 1920 until 1986, United States Metal Refining Company (USMR), an indirect wholly owned subsidiary of Cyprus Amax Minerals Company, owned and operated a copper smelter and refinery in the Borough of Carteret, New Jersey. Since the early 1980s, the site has been the subject of environmental investigation and remediation, primarily under the supervision of the New Jersey Department of Environmental Protection. On January 30, 2017, a class action titled </font><font style="font-family:Arial;font-size:10pt;text-decoration:underline;">Juan Duarte, Betsy Duarte and N.D., Infant, by Parents and Natural Guardians Juan Duarte and Betsy Duarte, Leroy Nobles and Betty Nobles, on behalf of themselves and all others similarly situated v. United States Metals Refining Company, Freeport-McMoRan Copper & Gold Inc. and Amax Realty Development, Inc.</font><font style="font-family:Arial;font-size:10pt;">, Docket No. 734-17, was filed in the Superior Court of New Jersey against USMR, FCX, and Amax Realty Development, Inc. The defendants have removed this litigation to the U.S. District Court for the District of New Jersey, where it remains pending. Pursuant to an amendment of the complaint in December of 2017, FCX is no longer a party to the lawsuit and FMC has been added to the lawsuit. The suit alleges that USMR generated and disposed of smelter waste at the site and allegedly released contaminants onsite and offsite through discharges to surface water and air emissions over a period of decades and seeks unspecified damages for economic losses, including loss of property value, medical monitoring, punitive damages and other damages. FCX intends to vigorously defend this matter.</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;">As a result of recent off-site soil sampling in public and private areas near the former Carteret smelter, FCX increased its associated environmental obligation for known and potential off-site environmental remediation by recording a </font><font style="font-family:Arial;font-size:10pt;">$59 million</font><font style="font-family:Arial;font-size:10pt;"> charge to operating income in 2017. Additional sampling is ongoing and could result in additional adjustments to the related environmental remediation obligation. </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 FCX subsidiaries and their predecessors 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. In January 2017, the Department of Justice, EPA, Navajo Nation, and two FCX-related subsidiaries reached an agreement regarding the financial contribution of the U.S. Government and the FCX subsidiaries and the scope of the environmental investigation and remediation work for the cleanup of </font><font style="font-family:Arial;font-size:10pt;">94</font><font style="font-family:Arial;font-size:10pt;"> former uranium mining sites on tribal lands. The settlement terms are outlined in a Consent Decree that was filed on January 17, 2017, in the U.S. District Court for the District of Arizona. Under the Consent Decree, which the government valued at over </font><font style="font-family:Arial;font-size:10pt;">$600 million</font><font style="font-family:Arial;font-size:10pt;">, FCX subsidiaries are in the process of performing the environmental investigation and remediation work at </font><font style="font-family:Arial;font-size:10pt;">94</font><font style="font-family:Arial;font-size:10pt;"> sites, and the United States contributed </font><font style="font-family:Arial;font-size:10pt;">$335 million</font><font style="font-family:Arial;font-size:10pt;"> into a trust fund to cover the government’s initial share of the costs. The program is expected to take more than </font><font style="font-family:Arial;font-size:10pt;">20</font><font style="font-family:Arial;font-size:10pt;"> years to complete. Based on updated cash flow and timing estimates, FCX reduced its associated obligation for that contingency by recording a </font><font style="font-family:Arial;font-size:10pt;">$41 million</font><font style="font-family:Arial;font-size:10pt;"> credit to operating income in second-quarter 2017 after receiving court approval of the Consent Decree. In addition to uranium activities on tribal lands, FCX is conducting site surveys of historical uranium mining claims associated with FCX subsidiaries on non-tribal federal lands in the Four Corners region. Under a memorandum of understanding with the U.S. Bureau of Land Management (BLM), site surveys are being performed on over </font><font style="font-family:Arial;font-size:10pt;">5,000</font><font style="font-family:Arial;font-size:10pt;"> mining claims, ranging from undisturbed claims to claims with mining features. Based on these surveys, BLM may provide no further action determinations for undisturbed claims or requests for additional assessment or closure activities for others.</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;">AROs.</font><font style="font-family:Arial;font-size:10pt;"> FCX’s ARO estimates are reflected on a third-party cost basis and are based on 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 other 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.

In connection with discharge permits, 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 applicable groundwater quality standards following the closure of discharging facilities and to abate groundwater or surface water contamination to meet applicable standards. In 2013, the WQCC adopted Supplemental Permitting Requirements for Copper Mining Facilities, which became effective on December 1, 2013, and specify 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. The rules are currently being challenged in the New Mexico Supreme Court by certain environmental organizations and the New Mexico Attorney General. Finalized closure plan requirements, including those resulting from application of the 2013 rules or the application of different standards if the rules are invalidated by the New Mexico Supreme Court, could result in material increases in closure costs for FCX’s New Mexico operations.</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;">FCX’s New Mexico operations also are subject to regulation under the 1993 New Mexico Mining Act (the Mining Act) and the related rules that are administered by the Mining and Minerals Division (MMD) of the New Mexico Energy, Minerals and Natural Resources Department. Under the Mining Act, mines are required to obtain approval of plans describing the reclamation to be performed following cessation of mining operations.

ADEQ has adopted regulations for its aquifer protection permit (APP) program that require permits for, among other things, certain facilities, activities and structures used for mining, leaching, concentrating and smelting, and require compliance with aquifer water quality standards at an applicable point of compliance well or location during both operations and closure. The APP program also may require mitigation and discharge reduction or elimination of some discharges.</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;">An application for an APP requires a proposed closure strategy that will meet applicable groundwater protection requirements following cessation of operations and an estimate of the cost to implement the closure strategy. An APP may specify closure requirements, which may include post-closure monitoring and maintenance. A more detailed closure plan must be submitted within 90 days after a permitted entity notifies ADEQ of its intent to cease operations. A permit applicant must demonstrate its financial ability to meet the closure costs approved by ADEQ. In 2014, the state enacted legislation requiring closure costs for facilities covered by APPs to be updated no more frequently than every five years and financial assurance mechanisms to be updated no more frequently than every two years. While some closure cost updates have occurred in the normal course as modifications to APPs, ADEQ has not yet formally notified FCX regarding the timetable for updating other closure cost estimates and financial assurance mechanisms for FCX’s Arizona mine sites. In 2016, ADEQ approved a closure plan update for Sierrita, which resulted in increased closure costs. FCX may be required to begin updating its closure cost estimates at other Arizona sites in 2018.</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;">Portions of Arizona mining facilities that operated after January 1, 1986, also are subject to the Arizona Mined Land Reclamation Act (AMLRA). AMLRA requires reclamation to achieve stability and safety consistent with post-mining land use objectives specified in a reclamation plan. Reclamation plans must be approved by the State Mine Inspector and must include an estimate of the cost to perform the reclamation measures specified in the plan along with financial assurance. During 2016, Safford submitted an update to its reclamation plan, which increased its reclamation costs. FCX will continue to evaluate options for future reclamation and closure activities at its operating and non-operating sites, which are likely to result in adjustments to FCX’s ARO liabilities, and those adjustments could be material.

Some reclamation costs will be incurred during mining activities, while the remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue for approximately </font><font style="font-family:Arial;font-size:10pt;color:#000000;text-decoration:none;">24</font><font style="font-family:Arial;font-size:10pt;"> years. At the end of 2016, PT-FI revised its estimates for an overburden stockpile to address ongoing erosion that occurred during 2016, a design change that increased the volume and updated cost estimates reflecting more recent productivity and costs at the overburden stockpile, which resulted in an increase in the ARO of </font><font style="font-family:Arial;font-size:10pt;">$372 million</font><font style="font-family:Arial;font-size:10pt;">.

In December 2010, the Indonesian government issued a regulation regarding mine reclamation and closure, which requires a company to provide a mine closure guarantee in the form of a time deposit placed in a state-owned bank in Indonesia. In accordance with its COW, PT-FI continues to work with the Department of Energy and Mineral Resources to review the application of these requirements, including discussion of other options for satisfaction of the mine closure guarantee. During 2017, PT-FI funded </font><font style="font-family:Arial;font-size:10pt;">$22 million</font><font style="font-family:Arial;font-size:10pt;"> into a restricted time deposit account for mine closure guarantees and </font><font style="font-family:Arial;font-size:10pt;">$7 million</font><font style="font-family:Arial;font-size:10pt;"> for reclamation guarantees.</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;">In October 2017, Indonesia’s Ministry of Environment and Forestry (the Ministry) notified PT-FI of administrative sanctions related to certain activities the Ministry indicated are not reflected in its environmental permit. The Ministry also notified PT-FI that certain operational activities were inconsistent with factors set forth in its environmental permitting studies and that additional monitoring and improvements need to be undertaken related to air quality, water drainage, treatment and handling of certain wastes, and tailings management. PT-FI has been engaged in a process to update its permits through submissions and dialogue with the Ministry, which began in late 2014. PT-FI believes that it has submitted the required documentation to update its permits and is in the process of addressing other points raised by the Ministry.</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;">Oil and Gas Properties. </font><font style="font-family:Arial;font-size:10pt;">Substantially all of FM O&G’s oil and gas leases require that, upon termination of economic production, the working interest owners plug and abandon non-producing wellbores, remove equipment and facilities from leased acreage, and restore land in accordance with applicable local, state and federal laws.

Management does not believe, based on currently available information, that the outcome of any legal proceeding will have a material adverse effect on FCX’s financial condition, although individual outcomes could be material to FCX’s operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period. </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-weight:bold;">Tax and Other Matters. </font><font style="font-family:Arial;font-size:10pt;">FCX’s operations are in multiple jurisdictions where uncertainties arise in the application of complex tax regulations. Some of these tax regimes are defined by contractual agreements with the local government, while others are defined by general tax laws and regulations. FCX and its subsidiaries are subject to reviews of its income tax filings and other tax payments, and disputes can arise with the taxing authorities over the interpretation of its contracts or laws. The final taxes paid may be dependent upon many factors, including negotiations with taxing authorities. In certain jurisdictions, FCX must pay a portion of the disputed amount to the local government in order to formally appeal the assessment. Such payment is recorded as a receivable if FCX believes the amount is collectible. </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;">Cerro Verde Royalty Dispute.</font><font style="font-family:Arial;font-size:10pt;"> SUNAT, the Peru national tax authority, has assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006, for the period December 2006 to December 2011. Cerro Verde contested these assessments because it believes that its 1998 stability agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing those minerals. </font><font style="font-family:Arial;font-size:10pt;">No</font><font style="font-family:Arial;font-size:10pt;"> assessments have been issued for the period from January 2012 through December 2013, and no assessments can be issued for years after 2013, as Cerro Verde began paying royalties on all of its production in January 2014 under its new </font><font style="font-family:Arial;font-size:10pt;">15</font><font style="font-family:Arial;font-size:10pt;">-year stability agreement.

style="font-family:Arial;font-size:10pt;">, PT-FI had paid </font><font style="font-family:Arial;font-size:10pt;">$417 million</font><font style="font-family:Arial;font-size:10pt;"> (included in other assets) on disputed tax assessments, which it believes is collectible. </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;">In December 2009, PT-FI was notified by Indonesian tax authorities that it was obligated to pay value-added taxes on certain goods imported after the year 2000. In December 2014, PT-FI paid </font><font style="font-family:Arial;font-size:10pt;">$269 million</font><font style="font-family:Arial;font-size:10pt;"> for value-added taxes for the period from November 2005 through the year 2009 and sought a refund. In March 2016, PT-FI collected a cash refund of </font><font style="font-family:Arial;font-size:10pt;">$196 million</font><font style="font-family:Arial;font-size:10pt;"> and </font><font style="font-family:Arial;font-size:10pt;">$38 million</font><font style="font-family:Arial;font-size:10pt;"> was offset against other tax liabilities. The remaining balance of the amount originally paid was reduced by currency exchange and other losses. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">PT-FI received assessments from the local regional tax authority in Papua, Indonesia, for additional taxes and penalties related to surface water taxes for the period from January 2011 through December 2017. PT-FI has filed or will file appeals with the Indonesia Tax Court. During 2017, the Indonesia Tax Court issued rulings against PT-FI with respect to assessments for additional taxes and penalties for the period from January 2011 through December 2015 in the amount of </font><font style="font-family:Arial;font-size:10pt;">$400 million</font><font style="font-family:Arial;font-size:10pt;"> (based on the exchange rate as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2017</font><font style="font-family:Arial;font-size:10pt;">, and including </font><font style="font-family:Arial;font-size:10pt;">$239 million</font><font style="font-family:Arial;font-size:10pt;"> in penalties). The aggregate amount of assessments received from January 2016 through December 2017 was an additional </font><font style="font-family:Arial;font-size:10pt;">$130 million</font><font style="font-family:Arial;font-size:10pt;"> (based on the exchange rate as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2017</font><font style="font-family:Arial;font-size:10pt;">, and including </font><font style="font-family:Arial;font-size:10pt;">$65 million</font><font style="font-family:Arial;font-size:10pt;"> in penalties). </font><font style="font-family:Arial;font-size:10pt;">No</font><font style="font-family:Arial;font-size:10pt;"> charges have been recorded for these assessments as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2017</font><font style="font-family:Arial;font-size:10pt;">, because PT-FI believes its COW exempts it from these payments and that it has the right to contest these assessments in the Indonesia Tax Court and ultimately the Indonesia Supreme Court. FCX estimates the total exposure based on the exchange rate as of </font><font style="font-family:Arial;font-size:10pt;">December 31, 2017</font><font style="font-family:Arial;font-size:10pt;">, totals </font><font style="font-family:Arial;font-size:10pt;">$530 million</font><font style="font-family:Arial;font-size:10pt;">, including penalties. As of </font><font style="font-family:Arial;font-size:10pt;">February 20, 2018</font><font style="font-family:Arial;font-size:10pt;">, PT-FI has not paid and does not intend to pay these assessments unless there is a mechanism established to secure a refund for any such payments upon the final court decision. Additionally, PT-FI is seeking to address this matter in connection with the ongoing negotiations with the Indonesian government to resolve PT-FI’s long-term mining rights. If the local regional tax authority were to force PT-FI to make these payments through the threat of expropriation of assets or other measures, such amounts may not be recoverable from the local regional tax authority and may result in a charge to operating income. At this time, PT-FI does not believe that the threat of seizure of PT-FI assets is imminent. </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;">In November 2017, PT-FI received an Indonesia Supreme Court decision that overturned a Tax Court case previously decided in favor of PT-FI related to 2005 assessments of less than </font><font style="font-family:Arial;font-size:10pt;">$1 million</font><font style="font-family:Arial;font-size:10pt;"> for employee withholding taxes. PT-FI has other pending cases at the Indonesia Supreme Court related to withholding taxes for employees and other service providers for the year 2005 and the year 2007, which total approximately </font><font style="font-family:Arial;font-size:10pt;">$66 million</font><font style="font-family:Arial;font-size:10pt;"> (based on the </font><font style="font-family:Arial;font-size:10pt;">December 31, 2017</font><font style="font-family:Arial;font-size:10pt;">, exchange rate), including penalties and interest. PT-FI believes the ruling in the case regarding the 2005 assessments is inconsistent with a ruling by the Indonesia Supreme Court in a similar case and is also inconsistent with PT-FI’s COW. PT-FI plans to continue to defend the outstanding cases and has not recorded charges for those cases because it does not believe a loss is probable. Because of a 2013 Ministry of Finance ruling that definitively defines withholding tax rates for employees and other service providers, and the statute of limitations, PT-FI does not believe it has exposure in any years after 2007.</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;">Letters of Credit, Bank Guarantees and Surety Bonds.</font><font style="font-family:Arial;font-size:10pt;">  Letters of credit and bank guarantees totaled </font><font style="font-family:Arial;font-size:10pt;color:#000000;text-decoration:none;">$283 million</font><font style="font-family:Arial;font-size:10pt;"> at </font><font style="font-family:Arial;font-size:10pt;color:#000000;text-decoration:none;">December 31, 2017</font><font style="font-family:Arial;font-size:10pt;">, primarily for environmental and asset retirement obligations, the Cerro Verde royalty dispute (refer to discussion above), workers’ compensation insurance programs, tax and customs obligations, and other commercial obligations.

FCX generally is self-insured for U.S. workers’ compensation, but purchases excess insurance up to statutory limits. An actuarial analysis is performed twice a year on the various casualty insurance programs covering FCX’s U.S.-based mining operations, including workers’ compensation, to estimate expected losses.

While FCX is not fully insured against all risks related to its oil and gas operations, its insurance policies provide limited coverage for losses or liabilities relating to pollution, with broader coverage for sudden and accidental occurrences.

The more significant areas requiring the use of management estimates include minerals reserve estimation; asset lives for depreciation, depletion and amortization; environmental obligations; asset retirement obligations; estimates of recoverable copper in mill and leach stockpiles; deferred taxes and valuation allowances; reserves for contingencies and litigation; asset impairment, including estimates used to derive future cash flows associated with those assets; pension benefits; and valuation of derivative instruments. Actual results could differ from those estimates. |
