Pursuant to Articles 10.16.1(a), (b) and 10.16.3 of the United States–Peru Trade Promotion Agreement (the “TPA”) and Article 36 of the Convention on the Settlement of Investment Disputes Between States and Nationals of Other States (the “ICSID Convention”), Freeport-McMoRan Inc. (“Freeport” or “Claimant”) and Freeport on behalf of Sociedad Minera Cerro Verde S.A.A. (“SMCV”), hereby submit this Notice of Arbitration against the Republic of Peru (“Peru” or the “Government”) for claims arising out of their investments in Cerro Verde, an open-pit copper and molybdenum mining complex located in the Arequipa Province of Peru.

I. INTRODUCTION

1. This Notice of Arbitration arises out of Peru’s violations of the contractual commitments it made more than 20 years ago to induce Freeport and SMCV to invest hundreds of millions of dollars into the Peruvian economy, Peru’s arbitrary imposition of penalties and interest against SMCV, and Peru’s efforts to sanitize its breaches through tainted proceedings before the Tax Tribunal that have violated Freeport’s and SMCV’s due process rights.

Breach of the Stability Agreement

2. In February 1998, the Government entered into a Stability Agreement with SMCV (the “Stability Agreement”) by which Peru granted SMCV administrative and fiscal stability for a 15-year period ending on 31 December 2013. The Stability Agreement extended the stabilization benefits to SMCV’s sole Mining Concession and its sole Beneficiation Concession at Cerro Verde—one of the world’s most productive copper mines.

3. Stability agreements, such as the one signed with SMCV, provide investors with the predictability needed to make immense, long-term investments without fear that a changing tax or administrative regime will destroy the value of their investments. Stability agreements are especially crucial in the mining industry, which is exceptionally capital-intensive, often requiring hundreds of millions or even billions of dollars of investments before the revenues from those investments can be recovered, often many years or even decades into the future. In short, as the Peruvian Mining Law recognizes, stability agreements serve the purpose of “promoting investment into the mining sector and facilitating the financing of mining projects.”1

4. As the Government intended, Freeport and SMCV relied on the Stability Agreement and invested hundreds of millions of dollars to develop the Cerro Verde mine,


1 Ex. CA-01, 1992 General Mining Law, Supreme Decree No. 014-92-EM, Art. 72.

[Page 2]

including US$240 million to expand the leaching and mining operations and to study the feasibility of a flotation plant, and subsequently a further US$850 million in a flotation plant (the “Flotation Plant”).

5. Peru has derived massive benefits from those investments. In 2018, Cerro Verde generated an average impact amounting to a remarkable 2% of Peru’s entire GDP and 29% of Arequipa’s GDP. SMCV’s investments have created employment for thousands of workers. In the Arequipa province, SMCV’s tax contributions accounted for over two-thirds of all tariffs and nearly half of all income taxes collected between 2005 and 2010. Moreover, since 2004, SMCV has gone above and beyond its legal obligations by voluntarily contributing millions of dollars to fund social initiatives for the benefit of the community in which it operates.

6. However, after receiving hundreds of millions of dollars from SMCV in investments, taxes and voluntary contributions, the Government reneged on its contractual obligation to provide SMCV with fiscal and administrative stability. In an abrupt about-face in 2009, the Government began assessing royalties on minerals processed by SMCV’s Flotation Plant under a Royalty Law that had been enacted in 2004, even though the Government itself had publicly recognized that SMCV was exempt from royalties by operation of the Stability Agreement. The Government also began assessing new taxes related to the Flotation Plant based on tax modifications and new tax rules.

7. The Government based its Assessments on a completely novel and restrictive interpretation of the stabilization benefits granted under the Mining Law and Regulations and the Stability Agreement pursuant to which the stabilization benefits applied only to the investments set forth in the feasibility study that the investor must submit to obtain the stability agreement. Under the Government’s interpretation, only SMCV’s leaching facility was covered by the Stability Agreement but not SMCV’s Flotation Plant. The Government adopted this novel and restrictive interpretation years after it had signed the Stability Agreement, and after Freeport and SMCV had made their US$850 million investment in the Flotation Plant in reliance on the terms of the Stability Agreement.

8. The Government’s novel and restrictive interpretation does not find any support in the terms of the Stability Agreement. On the contrary the Stability Agreement expressly notes that the Agreement arises from SMCV’s request for stabilization benefits “in relation with the investment in its concession”—not any subpart of the concession—and expressly provides further that the stabilization benefits apply “to the concessions [listed] in Annex I,” which includes both the leaching facility and the Flotation Plant.

[Page 3]

9. The Government’s novel position is equally inconsistent with Peruvian law. Neither the Royalty Law nor the Mining Law and Regulations make any distinction between projects within a single concession. Rather, under the Royalty Law, royalties are imposed on the extraction of minerals of a mining concession regardless of how they are processed, and under the Mining Law and Regulations, stabilization benefits apply to all activities within the relevant concessions or Economic Administrative Units (“EAU”). Nothing in these laws (or in the Stability Agreement) suggests that a company is meant to split its mining activities in the same concession into stabilized and unstabilized investments.

10. In addition to contravening Peruvian laws and the Stability Agreement itself, the Government’s novel and restrictive position also defies economic common sense. SMCV’s Concessions are financed and operate as a single integrated enterprise. To provide the confidence and predictability required to induce initial and continued investment, stabilization benefits must likewise apply to the Mining and Beneficiation Concessions as a whole, not to any particular investment or asset within the Concessions. Peru’s novel and restrictive position results in SMCV’s single Mining Concession and single Beneficiation Concession having multiple fiscal regimes even though Peruvian law and regulations provide no guidance whatsoever about how a mining company is meant to split its integrated activities within a single concession into stabilized and non-stabilized investments.

Breach of the TPA

11. The Government’s arbitrary and unlawful conduct did not end with the imposition of royalties and taxes in breach of the Stability Agreement. In blatant violation of the TPA, the Government more than doubled its windfall from the Royalty and Tax Assessments by arbitrarily failing to waive hundreds of millions of dollars of punitive penalties and interest that Peru’s Tax Authority (“SUNAT”) imposed on SMCV, even though waiver of those penalties and interest was mandatory. As a result of the extraordinarily punitive interest rate that SUNAT applied, penalties and interest now account for more than 60% of Freeport’s damages.

12. Under Peruvian law, the Government must waive penalties and interest where the proper interpretation of the applicable legal provision is subject to reasonable doubt. Plainly, such reasonable doubt exists here: the Government’s novel and restrictive interpretation of the scope of stabilization benefits finds no support in law or contract, is without precedent, and is contrary to both prevailing industry practice and the purpose of the stability regime itself. Moreover, it is contrary to contemporaneous public statements by Government officials that SMCV did not have to pay royalties as a result of the Stability

[Page 4]

Agreement. And in 2014, a first instance Contentious Administrative Court agreed with SMCV’s position. Although other courts subsequently reversed that decision, the divergent decisions of Peru’s own courts clearly illustrate that the relevant legal provisions are—at a bare minimum—subject to reasonable doubt.

13. By arbitrarily failing to waive these penalties and interest, as it was clearly required to do, the Government effectively penalized SMCV for seeking recourse before SUNAT and the Tax Tribunal to challenge the Government’s Assessments, as it was entitled to do. As a result of the extraordinarily punitive interest rate that SUNAT applied, penalties and interest now account for more than 60% of Freeport’s damages.

14. The Government has further violated the TPA by failing to afford SMCV a fair hearing when it challenged SUNAT Assessments before the Tax Tribunal. Freeport has now learned that, instead of having SMCV’s challenges decided by Chambers consisting of three independent and impartial judges, as required under Peruvian law, when SMCV filed its first challenge to SUNAT’s Royalty Assessments, the decision confirming the Assessments was drafted by the administrative secretary of the Tax Tribunal President. The Tax Tribunal President and her assistant should have no role in deciding cases. Moreover, that assistant was not even present at the hearing when SMCV presented its arguments. The Chambers hearing SMCV’s other challenges of SUNAT’s Royalty Assessments then simply copy-pasted virtually all or major parts of the decision drafted by the President’s assistant.

15. Further, SMCV’s challenge to certain Royalty Assessments was heard—and rejected—by a judge who had not only worked for the same SUNAT division that confirmed the Royalty Assessments on which he was slated to rule, but had also in his capacity as a SUNAT lawyer defended the Government’s novel and restrictive interpretation of the Stability Agreement in litigation against SMCV before the Contentious Administrative Courts. Despite the obviously disqualifying conflict of interest of SMCV’s opposing counsel becoming the arbiter of the case, the Tax Tribunal rejected in a plenary vote SMCV’s application to remove the judge. Barely two weeks after the Tax Tribunal rendered its decision against SMCV, in a tacit admission of judicial impropriety, the Government amended the Tax Code to require judges to recuse themselves under such circumstances, but did not have a different, unconflicted panel reconsider the decision against SMCV.

16. Finally, the Government also breached the TPA by arbitrarily refusing to fully repay SMCV for payments made under former President Humala’s Special Contribution (GEM) Program, which the Government established to collect additional revenue from mining companies benefitting from stability agreements to dedicate a larger portion of their proceeds to

[Page 5]

projects promoting social welfare in Peru. Based on the good faith belief that it was exempted from paying royalties while the Stability Agreement remained in force, SMCV participated in the GEM Program and contributed over US$100 million.

17. The Government cannot have it both ways: if its purported taxes and royalties are not barred by the Stability Agreement, then SMCV is entitled under Peruvian law to a full refund of the GEM payments that it made on the assumption that its investments were stabilized and not subject to royalties. Yet, when SMCV requested that Peru reimburse it for the excess payments under the GEM Program, the Government arbitrarily approved only a partial reimbursement of these overpayments.

18. Freeport accordingly claims, on its own behalf and that of SMCV, that:

a) Peru has violated the Stability Agreement by confirming SUNAT’s unlawful Assessment of Royalties and Taxes; and

b) Peru has violated Articles 10.4 and 10.5 of the TPA by (i) arbitrarily refusing to waive SUNAT’s extraordinarily punitive penalties and interest, as required by law; (ii) denying SMCV a fair hearing before the Tax Tribunal; and (iii) arbitrarily refusing to fully repay SMCV the GEM overpayments.

19. As a result of the Government’s repeated and continuous breaches of the Stability Agreement and the TPA, Freeport seeks damages on its own behalf and that of SMCV in an amount exceeding US$1 billion plus pre- and post-award interest, and its legal fees and costs.

III. BACKGROUND

A. Freeport’s and SMCV’s Substantial Investments in Cerro Verde Have Greatly Benefited Peru.

24. Cerro Verde is an open-pit copper and molybdenum mining complex located about 30 km south of Arequipa, Peru.6 Mining at Cerro Verde dates back as far as the mid-1880s, but output from the mining complex greatly increased after the Peruvian Government privatized the mine in the 1990s.7

25. As a result of several large capital investments and expansions by Freeport and SMCV’s other shareholders, including a multibillion dollar investment completed in 2016, the Cerro Verde mine now has an annual output of approximately one billion pounds of copper and

30 million pounds of molybdenum,8 making it one of the most productive and technologically advanced copper mines in the world.

26. SMCV currently employs around 5,000 full-time Peruvian employees at Cerro Verde and around 1,800 contractors. But SMCV’s contribution to the local and national economy goes well beyond formal employment. A 2018 study of Cerro Verde’s economic impact found that Cerro Verde’s operations and investments generated an average impact (direct and indirect) of 2% of Peru’s national GDP and 29% of Arequipa’s GDP in 2018.9

27. SMCV has made other significant contributions to the region. For example, in 2012, SMCV completed the design, construction, and management of a much needed potable water treatment plant for the Municipality of Arequipa. This US$120 million facility currently provides water to over 350,000 people but will be able to serve 750,000 people as Arequipa continues to grow.10 SMCV invested a further US$30 million in the distribution lines of the water treatment plant and over US$30 million to the construction and operation of regional dams, including Pillones, Bamputañe, and San José de Uzuña, preventing water loss to the ocean and ensuring increased availability of water year-round.11 SMCV has likewise co-financed the La Escalerilla Waste Treatment Plant and the La Enlozada Waste Water Treatment Plant, which had an initial cost of US$454 million dollars. Currently, SMCV operates and maintains La Enlozada, allowing Arequipenians to benefit from the water treatment system without paying for it. And while this investment has allowed SMCV to obtain water for its own operations, it has also treated 95% of the city’s sewage and improved the quality of the Chili River, the environment more generally, and the health of Arequipenians. SMCV also makes ongoing contributions to support community development activities, including support for local nurseries, small business employment, women and community trainings, communications, and other sustainable development activities.12

B. Freeport and SMCV Invested in Cerro Verde Relying on the Government’s Obligation to Provide Fiscal and Administrative Stability.

28. SMCV holds two types of concessions at Cerro Verde: (i) a concession to explore and extract mineral resources in an area called “Cerro Verde No. 1, No. 2, and No. 3" (the “Mining Concession");13 and (ii) a concession to process the minerals extracted under the Mining Concession called “Planta de Beneficio Cerro Verde” (the “Beneficiation Concession”).14 Together, these two concessions form SMCV’s sole EAU.15

29. Historically, SMCV has employed two different metallurgical processes to refine the Cerro Verde minerals in its Beneficiation Concession: leaching and flotation. In simple terms, leaching is a process through which metals are separated from waste rock using an aqueous reagent. Flotation is a chemical process through which sulfide minerals are separated from each other and from waste rock. SMCV extracts all of the Cerro Verde minerals under its sole Mining Concession and processes all of the minerals either through leaching or flotation under its sole Beneficiation Concession which was approved by the Ministry of Energy and Mines.

30. The Government created SMCV more than two decades ago. In August 1993, as part of a broader privatization process in Peru, the state-owned company Empresa Minera del Perú S.A. (“Minero Perú”), which had operated Cerro Verde for the previous two decades, created SMCV, transferred its Mining and Beneficiation Concessions to SMCV and offered SMCV for sale.16 In March 1994, Minero Perú sold 91.65% of its SMCV shares to Cyprus Climax Metals Company (the “1994 Share Purchase Agreement”), which then assigned its rights under the 1994 Share Purchase Agreement to Cyprus Amax Mineral Company (together with Cyprus Climax Metals, “Cyprus”).17 In 1999, Freeport’s predecessor Phelps Dodge Corporation acquired Cyprus and with it a majority of SMCV and the Cerro Verde mining operations.18

31. In the 1994 Share Purchase Agreement, Cyprus agreed with the Peruvian Government that it would invest in the Cerro Verde mining facilities, including by

[Page 9]

(i) expanding and modernizing the existing leaching facilities; and (ii) installing new mill and flotation facilities for processing primary sulfides.19 At the time, SMCV processed mostly leachable ore, but the Mining Concession contained significant primary sulfide deposits that could not be processed through leaching and were being processed in a small concentrator. The potential for processing the primary sulfides at a larger scale (i.e., in a larger concentrator than the one Cyprus acquired during the privatization process) had been studied since 1972, including in a 1985 feasibility study commissioned by Minero Perú.20 Processing Cerro Verde’s primary sulfides was of crucial importance to prolong the life of the mine because the leachable reserves were expected to be exhausted by 2014.21

32. In compliance with the 1994 Share Purchase Agreement, SMCV prepared a series of studies exploring the possibility of further expanding the leaching facilities. In early 1996, SMCV completed a feasibility study for a US$237 million investment program to expand the existing leaching plant and improve the associated infrastructure using the latest technology, thereby increasing Cerro Verde’s annual production capacity from 72 million pounds to 105 million pounds (the “1996 Feasibility Study”).22

33. As part of the investments included in the 1996 Feasibility Study, SMCV also completed studies exploring the feasibility of installing the new mill and flotation facilities for processing primary sulfides.23 At the time, the studies concluded that installing a mill would not be economically feasible,24 among other reasons because of the high cost of power in the Arequipa region and the absence of an economic water source.25 SMCV nonetheless

[Page 10]

committed to conducting additional studies and testing to establish whether it could be economically feasible to process Cerro Verde’s primary sulfides.26

34. As set forth in the 1994 Share Purchase Agreement, on 25 January 1996, SMCV filed an application with the Ministry of Energy and Mines requesting fiscal and administrative stability for its Mining Concession pursuant to Article 82 of the Mining Law.27 The Mining Law provides that a mining company that has committed to making a large capital investment either to build a new mining project or expand an existing one can request “tax stability which shall be guaranteed by contract subscribed with the State for a period of fifteen years, starting from the year in which [the applicant company] prove[s] the implementation of the investment or expansion, as appropriate.”28 In turn, Article 14 of the Mining Regulations specifies that tax stability guarantees “that [the title holder] will be subject only to the fiscal regime in force when the feasibility study is approved, and any tax created thereafter is not applicable.”29

35. As stated in the Mining Law, the purpose of these stability agreements is “to promote investment and facilitate the financing of mining projects.”30 The stability agreements provide investors with predictability by, among other benefits, freezing applicable fiscal laws and regulations. Such stabilization benefits are a common feature in the mining industry. Mining is extremely capital-intensive, often requiring hundreds of millions of dollars of investment before any revenue is generated. Investors are thus more likely to obtain financing and commit significant amounts of capital if they are protected from unforeseen changes in the law and can predict with reasonable certainty what their fiscal burden will be years into the future.

36. As evidence of their commitment to make a minimum investment (the amount of which determines the right to apply either for a ten or fifteen-year stability agreement), the Mining Law requires investors to “submit a technical and economic feasibility study” for approval by the General Directorate of Mining.31 SMCV accordingly supported its application

for a stability agreement by submitting its 1996 Feasibility Study, which the General Directorate of Mining approved on 6 May 1996.32

37. On 26 February 1998, after the Ministry of Energy and Mines confirmed that SMCV made the required minimum investment, SMCV and the Government executed the Stability Agreement.33 The Stability Agreement stabilized the fiscal and administrative regimes existing on May 1996 for a period of 15 years from 1 January 1999 to 31 December 2013. Specifically, the Agreement provided that “the modifications or new rules that may be issued” during the 15-year period of stabilization “will not affect [SMCV] in any way,” including any changes to the income tax regime, custom duties or municipal taxes.34 The Stability Agreement moreover excluded the application of any law passed after 6 May 1996 that “directly or indirectly, denaturalizes the guarantees provided” by the Agreement.35

38. Clause 1 of the Stability Agreement referred to SMCV’s Concessions as the “Cerro Verde Leaching Project,” but expressly stated that SMCV had requested stabilization benefits “in relation with the investment in its concession: Cerro Verde No. 1, No. 2, and No. 3.”36 Clause 3 further provided that the stabilization benefits were “circumscribed to the concessions [listed] in Annex I.”37 Annex I expressly listed both of SMCV’s concessions, namely the Mining Concession and the Beneficiation Concession.38

39. On 3 December 1999, the Government confirmed that SMCV had successfully completed construction of the expanded leaching facilities as set forth in the 1996 Feasibility Study.39

40. As required under the terms of the 1994 Share Purchase Agreement with the Government and a March 2001 settlement agreement with Minero Perú, SMCV continued exploring the possibility of processing Cerro Verde’s primary sulfides.40

41. Specifically, in July 2003, SMCV engaged Fluor Canada Ltd. (“Fluor”) to evaluate further the addition of a “concentrator to treat primary sulfide ore from the existing mining operation at Cerro Verde.”41 Fluor evaluated two main technology options for treating the primary sulfide ore, milling and pebble crushing (known as “SABC”) and high pressure grinding rolls (known as “HPGR”) and ball mills followed by flotation concentration.42 The new HPGR technology presented “financial advantages due to lower operating costs.”43 Prior constraints regarding the absence of economic power and water sources were resolved through upgrades in power lines and SMCV’s participation in a reservoir project that secured water rights for Cerro Verde.44 Fluor thus concluded that “[t]he project as currently conceived appears to have sound investment potential”45 and that the expected cost of the new facilities for treating the Cerro Verde primary sulfides would exceed US$800 million.46

42. On 30 January 2004, SMCV submitted a proposal to the Government to invest the US$800 million needed to construct the new facilities (the “Flotation Plant”), which the Government approved on 9 December 2004.47 During the two-year construction of the Flotation Plant, SMCV ultimately invested a total of US$850 million and employed 11,500 people.48

43. In late 2006, SMCV started the test period for operating the Flotation Plant.49 On 26 February 2007, the Government issued a Resolution approving the extension of SMCV’s Beneficiation Concession to include the Flotation Plant.50 Since the Stability Agreement expressly covered the Beneficiation Concession, the Government’s Resolution extending the

Beneficiation Concession to include the Flotation Plant shows that the Government itself understood that the stabilization benefits also covered the Flotation Plant.51

44. In March 2007, Phelps Dodge merged with Freeport, which became the indirect majority owner of SMCV.52

C. Peru Assessed Royalties and Taxes in Breach of the Stability Agreement.

45. On 24 June 2004, Peru passed a new law “establishing a mining royalty”53 (the “Royalty Law”). The Royalty Law defines royalties as “the economic consideration that the title holder of the mining concession pays to the State for the exploitation of metallic and non-metallic mineral resources.”54

46. When the Government passed the Royalty Law, senior Peruvian Government officials acknowledged publicly that SMCV and other mining companies that had executed stability agreements with the Government would be exempted from royalty payments while their stability agreements remained in force.

47. For instance, in May 2006, SUNAT’s then-National Intendent, Ms. Nahil Hirsh, and the then-Minister of Economy and Finance, Mr. Fernando Zavala, stated in a presentation to the Peruvian Congress that SMCV and other mining companies were not subject to the Royalty Law because of stability agreements with the Government.55 The El Comercio newspaper quoted Ms. Hirsh as stating that SMCV was among “10 companies that were not paying royalties” because of “administrative stabilization contracts, agreements with contract-law status that guarantee exchange rate, tax and administrative stability, and that shield these companies against the Royalty Law and other obligations created after their contracts.”56

48. In the good faith belief that it was fully exempted from paying any royalties under the Royalty Law until the Stability Agreement expired at the end of December 2013, SMCV made no royalty payments for any of the minerals extracted in the Cerro Verde Mining Concessions. The Government nonetheless received significant revenues from the Cerro Verde

mine, particularly after SMCV had expanded its leaching facilities and constructed the Flotation Plant. During the period between 2005 and 2010, SMCV’s tax contributions represented approximately 82% of all tariffs and 47% of all income taxes collected in the Arequipa Province.57

49. Moreover, because SMCV was fully exempted from paying royalties, it agreed to participate in President Alan Garcia’s Voluntary Contribution Program, which sought to encourage mining companies to dedicate a larger portion of their proceeds to projects promoting social welfare and development in the communities where their mining projects were located. Specifically, on 18 January 2007, SMCV signed a Voluntary Contribution Agreement with the Government by which SMCV agreed to contribute 3.75% of its annual net profits to local and regional funds.58 SMCV ultimately contributed over US$130 million to the funds for projects supporting childhood nutrition, primary education, health, and other social goals.

50. After the Voluntary Contribution Agreement expired, SMCV participated in President Humala’s Special Contribution (GEM) Program, which sought additional payments to the Government based on profits accruing from mining activities subject to stabilization. On 28 February 2012, SMCV signed a GEM Agreement with the Government.59 Ultimately, SMCV paid more than US$100 million in GEM payments.60 The Government accepted those payments, thereby ratifying SMCV’s understanding that it was exempted from paying royalties and that it was not entitled to any deductions on account of royalty payments.61

51. Yet, after receiving these hundreds of millions of dollars from SMCV in investments, taxes and GEM payments, the Government reneged on its contractual obligation to provide SMCV with the fiscal and administrative stability it had promised. On 17 August 2009, SUNAT assessed royalties under the Royalty Law against SMCV in the

amount of around US$28.87 million62 for the minerals processed in the Flotation Plant between December 2006 and December 2007 (the “2006/07 Royalty Assessments”).63 In addition, SUNAT also imposed on SMCV penalties and interest accruing at a punitive rate of 14.4% per year, which as of 31 December 2019 accumulated to around US$77.12 million, more than twice the value of the 2006/07 Royalty Assessments.64

52. SUNAT’s 2006/07 Royalty Assessments reflected a complete about-face by the Government and were based on an entirely novel and restrictive interpretation of the Mining Law and Regulations. Although SMCV extracted all of the Cerro Verde minerals under its sole Mining Concession and processed all of those minerals under its sole Beneficiation Concession, both of which were covered by the 1998 Stabilization Agreement, SUNAT took the baseless position that only the minerals processed by the leaching facility were covered by the Stability Agreement, whereas the minerals processed by the flotation plant within the same Beneficiation Concession were not.65

53. SUNAT attempted to justify this artificial distinction by claiming that stabilization benefits were limited to the investments set forth in the feasibility study submitted to the Government for purposes of obtaining stabilization benefits.66 Under SUNAT’s novel and restrictive interpretation, the scope of the Stability Agreement was therefore allegedly limited to the investments set forth in the 1996 Feasibility Study.67

54. SUNAT’s novel and restrictive position violated the plain terms of the Royalty Law, which imposes royalties on the extraction of mineral resources, irrespective of whether the minerals are leached, processed in a flotation plant, or sold without any processing.68 Moreover, neither the Mining Law nor the Regulations limit stabilization benefits to the specific investments set forth in the feasibility study. On the contrary, they expressly provide that stabilization benefits attach to the activities performed by the “title holder of the mining

63 See Ex. CE-31, 17 Aug. 2009 SUNAT Royalty Assessment, 2006-07 Case.

64 On 10 October 2013, SMCV signed (under protest) an installment plan with SUNAT for the payment of the royalties and penalties and interest due to the Government. Under the installment payment plan, the applicable interest from 10 October 2013 until SMCV fully pays all amounts due is 11.52%. See Ex. CE-99, 10 Oct. 2013 SUNAT Arequipa Regional Office Administrative Decision No. 0510170003363.

activity”69 within either a particular concession or a particular EAU consisting of multiple related concessions.70 For instance, Article 83 of the Mining Law provides that stability benefits “extend exclusively to the activities of the mining company in whose favor the investment is made,”71 without any limitation to the investments set forth in the feasibility study. Likewise, Article 22 of the Regulations provides that stability benefits apply to a mining company “exclusively for investments it makes in the concessions or Economic Administrative Units,”72 also without any limitation. And Article 25 of the Regulations refers to a mining company “expanding its facilities or [making] new investments that benefit from the contractual stability guarantee.73

55. In addition to being inconsistent with the Royalty Law, the Mining Law, and the Regulations, SUNAT’s novel and restrictive position also ran counter to prevailing industry practice and commercial sense. SUNAT’s position results in a single mining concession having multiple fiscal and administrative regimes, even though stability agreements (including the Stability Agreement at issue here) and Peruvian law and regulations provide no guidance whatsoever about how a mining company is meant to split its activities within a single concession into stabilized and unstabilized investments for accounting and tax (or any other) purposes. At the same time, SUNAT’s novel and restrictive position contradicts the very purpose of the stability regime—to provide mining companies like Freeport and SMCV with the clarity and predictability they need to invest and attract financing for their capital-intensive investments.

56. Accordingly, on 15 September 2009, SMCV requested that SUNAT reconsider the 2006/07 Royalty Assessments.74 A few months later, on 31 March 2010, SUNAT rejected SMCV’s reconsideration request.75

57. After the initial 2006/07 Royalty Assessments, SUNAT continued to issue further Royalty Assessments against SMCV, which were also premised on its novel and

approximately US$7.36 million, plus penalties and interest which as of 31 December 2019 accumulated to around US$9.99 million.82 On 15 February 2018, SMCV submitted a reconsideration request, which SUNAT rejected on 12 October 2018.83

58. In addition to the Royalty Assessments, the Government imposed on SMCV several Tax Assessments in violation of the Stability Agreement, which it also based on its novel and restrictive interpretation of the scope of stabilization benefits. For instance, SUNAT and the Tax Tribunal have (i) imposed on SMCV the then-current 19% general sales tax rate, instead of the stabilized 18% rate; (ii) imposed an additional 4.1% income tax rate on non-deductible expenses not in effect at the time of, and therefore not permitted by, the Stability Agreement; (iii) imposed on SMCV a tax depreciation regime that is different to the regime that would apply pursuant to the Mining Law and Regulations and the Stability

Agreement; (iv) imposed a Special Mining Tax and Complementary Mining Pension Fund Tax that were created during the life of the Stability Agreement and therefore did not apply to SMCV while its Stability Agreement remained in force; and (v) contrary to Article 22 of the Regulations, penalized SMCV for not keeping separate accounts for the minerals processed in the two different facilities, despite SMCV extracting all minerals under its one and only Mining Concession.88 The various Tax Assessments that Peru has imposed in violation of the Stability Agreement and the Mining Law and Regulations are listed in Annex A and Annex B hereto (Annex A lists the Tax Assessments that SMCV appealed before the Tax Tribunal and Annex B lists the Tax Assessments that SMCV challenged before SUNAT but not before the Tax Tribunal because pursuing any such appeals would have been futile at that stage).

59. In total, Peru has unlawfully imposed around US$240.05 million in Royalty Assessments and around US$441.41 million in extraordinarily punitive penalties and interest on those Assessments. Similarly, Peru has unlawfully imposed around US$239.85 in Tax Assessments and around US$216.63 in extraordinarily punitive penalties and interest on those Assessments.

D. Peru Rebuffed SMCV’s Efforts to Challenge the Royalty Assessments.

60. After SUNAT denied SMCV’s reconsideration requests of the 2006/07 and 2008 Royalty Assessments, SMCV appealed SUNAT’s Assessments to the Tax Tribunal. In Peru, the Tax Tribunal forms part of the Ministry of Economy and Finance (the “MEF”) within the Executive Branch of the Peruvian Government and is the “last administrative instance in tax and custom matters.”89 A SUNAT Assessment therefore does not become final and binding on the taxpayer until the Tax Tribunal resolves the appeal confirming the Assessment.

61. Tax Tribunal judges are supposed to be independent and impartial, but in practice have perverse incentives to decide cases involving significant monetary value amounts in favor of SUNAT and the judges’ employer, the MEF. The MEF appoints and employs the Tax Tribunal judges, and by law 2.3% of the total tax funds and 1.2% of the total custom funds

raised by SUNAT are assigned to the Tax Tribunal’s yearly budget.90 Therefore, the higher the Government’s tax and custom revenues, the higher the budget for the Tax Tribunal.

62. In SMCV’s case, the Tax Tribunal was neither independent nor impartial and instead worked closely with SUNAT to uphold the 2006/07, 2008, 2009, 2010/11, and 4Q 2011 Royalty Assessments in violation of SMCV’s due process rights.

1. SMCV’s Challenge to the 2006/07 and 2008 Royalty Assessments.

63. SMCV appealed the 2006/07 Royalty Assessments to the Tax Tribunal on 22 June 2010, and the 2008 Royalty Assessments on 10 March 2011.91 It has been the Tax Tribunal’s long-standing practice to decide cases in the order in which they are filed.92 Accordingly, the Tax Tribunal should have first resolved SMCV’s appeal on the 2006/07 Royalty Assessments. But following a series of grave irregularities, the Tax Tribunal first issued a decision regarding SMCV’s appeal of the 2008 Royalty Assessments.93

64. Specifically, on 5 April 2013, Chamber No. 10 of the Tax Tribunal, which was assigned the first-filed appeal of the 2006/07 Royalty Assessments, held an oral hearing.94 Before Chamber No. 10 could render its decision, however, Chamber No. 1, which was assigned the later-filed appeal of the 2008 Royalty Assessments, suddenly and unexpectedly

decided to hold an oral hearing on 2 May 2013.95 This was highly unusual since SMCV filed its appeal of the 2008 Royalty Assessments almost nine months after filing the appeal of the 2006/07 Assessments.96

65. As a review of the Tax Tribunal case files now reveals, on 24 April 2013, the Tax Tribunal President’s assistant, Ms. Ursula Villanueva, sent an ex parte communication to SUNAT Arequipa requesting a copy of SMCV’s first Stability Agreement of 1994, which SUNAT promptly provided her that same day.97 According to the Tax Tribunal’s rules of procedure, the Tax Tribunal may request parties to provide additional documents but only if the request is signed by the judge presiding over the case (“vocal ponente”), not by the assistant to the Tax Tribunal President, as was the case here.98 The request also must be made through a formal written communication and not by ex parte emails, but the assistant to the Tax Tribunal President violated both of these rules.99

66. On 21 May 2013, within just weeks of holding an oral hearing and before Chamber No. 10 rendered its decision on the first-filed appeal of the 2006/07 Assessments, Chamber No. 1 rendered its decision confirming the 2008 Royalty Assessments and rejecting all of SMCV’s claims.100

67. The Chamber No. 1 decision confirming the 2008 Royalty Assessments bears the initials of Ms. Villanueva on the signature page, which strongly suggests that she, and not a judge or clerk of Chamber No. 1, drafted the decision.101 According to the Tax Tribunal’s rules of procedure, the Tax Tribunal President and her assistant have no role in drafting decisions or deliberating on cases.102 That role falls exclusively to the judges and clerks of the presiding Chambers.103 Indeed, Ms. Villanueva was not even present when Chamber No. 1 heard oral argument on the appeal to the 2008 Royalty Assessment.104

68. The Tax Tribunal’s case files further show that on 27 May 2013, the Tax Tribunal notified SUNAT of its decision confirming SUNAT’s 2008 Royalty Assessments and rejecting SMCV’s appeal.105 In violation of basic due process, SUNAT submitted a copy of the decision the following day to Chamber No. 10, which had not yet issued its decision, without notifying SMCV of the Tax Tribunal’s decision confirming the 2008 Royalty Assessments and without copying SMCV in its communication.106

69. On 30 May 2013, a mere two days after SUNAT provided a copy of the Chamber No. 1 decision confirming the 2008 Royalty Assessments to Chamber No. 10, Chamber No. 10 issued its decision confirming SUNAT’s 2006/07 Assessments and rejecting all of SMCV’s claims.107 Chamber No. 10 did not draft its own decision or articulate its own analysis as to why SMCV’s Stability Agreement should be arbitrarily restricted to the investments set forth in the 1996 Feasibility Study. Instead, Chamber No. 10 copied the Chamber No. 1 decision almost verbatim.108 What is more, Chamber No. 10’s copy-and-paste decision did not contain the initials of any clerk who worked on the case or who should have

assisted the judges with the drafting.109 This is highly unusual and strongly suggests that Chamber No. 10 played no role in preparing the decision.

70. It was not until 20 June 2013, several weeks after both decisions were rendered, that SMCV was finally notified of the decisions.110

71. On 26 June 2013, promptly after receiving the two almost identically worded decisions, SMCV requested that the Tax Tribunal exempt it from paying penalties and interest on the 2006/07 and 2008 Royalty Assessments.111 Pursuant to Article 170 of the Peruvian Tax Code and Article 12 of Law 28969, penalties and interest are not applicable and must be waived when the proper interpretation of the applicable legal provision is subject to “reasonable doubt.”112 There clearly was such reasonable doubt here: the Government based its Royalty Assessments on a completely novel and restrictive interpretation of the scope of stabilization benefits that found no support in law or contract, was without precedent, and was contrary both to prevailing industry practice and the purpose of the stability regime itself. Moreover, both the Ministry of Energy and Mines and SUNAT had publicly included SMCV among the companies that did not have to pay royalties as a result of a stability agreement.113

72. On 15 July 2013, the Tax Tribunal nevertheless denied SMCV’s waiver requests.114 It did so on the pretextual and arbitrary ground that SMCV should have expressly requested a waiver of penalties and interest in its appeals to the Tax Tribunal,115 even though

the Tax Tribunal has accepted waiver requests from other taxpayers that were submitted after their corresponding appeal decisions had been issued.116

73. On 18 September 2013, SMCV appealed the Tax Tribunal decision confirming SUNAT’s 2008 Royalty Assessments to the Contentious Administrative Courts, which serve as Peru’s independent and neutral courts on administrative matters within the Judicial Branch.117

74. On 17 December 2014, the first instance Contentious Administrative Court annulled SUNAT’s 2008 Royalty Assessments.118 The Court rightly agreed with SMCV that the Mining Law and Regulations grant “legal stability . . . to the title holder of the mining activity . . . to exercise its activities, specifically to those that exercise mining activities in one concession or several concessions grouped in one Economic-Administrative Unit”119 and that “the benefits are granted to the title holder for the activities it performs within its concessions or Economic Administrative Units.”120 The Court accordingly concluded that SMCV’s “activities related to the flotation of primary sulfides are being performed within the stability time period granted to [SMCV]” and that, as a result, SMCV did not owe any Royalty payments.121

75. On 29 January 2016, the Appellate Court reversed the first instance Court’s decision and also denied SMCV’s entitlement to a waiver of penalties and interest on the same pretextual and arbitrary ground as the Tax Tribunal.122 The Appellate Court thus denied SMCV’s entitlement to a waiver without considering its arguments on the merits or that under Peruvian law inconsistent court decisions constitute proof of “reasonable doubt” about the proper interpretation of the legal provisions at issue.123

76. On 23 February 2016, SMCV appealed the Appellate Court’s decision before the Supreme Court, in a last attempt to allow the Peruvian courts to vindicate SMCV’s rights

with regard to the 2008 Royalty Assessments.124 On 18 August 2017, the Supreme Court dismissed all of SMCV’s claims and upheld the Government’s novel and restrictive position that SMCV’s stabilization rights under the Stability Agreement were limited to the minerals processed in the leaching facilities.125 The Supreme Court also arbitrarily upheld the Appellate Court’s decision denying SMCV’s entitlement to a waiver of penalties and interest, once again without even considering SMCV’s arguments on the merits.126

77. SMCV similarly appealed the Tax Tribunal decision confirming the 2006/07 Royalty Assessments to the Contentious Administrative Courts, including up to the Supreme Court.127 The First and Second Instance Courts upheld SUNAT’s novel and restrictive position. Even though the hearing was held more than 15 months ago on 20 November 2018, the Supreme Court did not issue its decision with respect to the 2006/07 Royalty Assessments and SMCV has now withdrawn its appeal.128

2. SMCV’s Challenge to the 2009 and 2010/11 Royalty Assessments.

78. SMCV’s appeals of the 2009 and 2010/11 Royalty Assessments to the Tax Tribunal followed a similarly irregular pattern to the appeals of the 2006/07 and 2008 Royalty Assessments.

79. On 12 January 2012, SMCV appealed SUNAT’s 2009 Royalty Assessments to the Tax Tribunal.129 That appeal remained pending for over six years. Several years later, on 22 March 2017, SMCV appealed SUNAT’s 2010/11 Royalty Assessments.130

80. The Tax Tribunal assigned Chamber No. 1 to hear SMCV’s appeal of the 2010/11 Royalty Assessments—the same Chamber that had committed grave irregularities in upholding the 2008 Royalty Assessments.131 Two of the three judges in Chamber No. 1

remained the same. The third judge, Victor Mejía Ninacondor, had joined the Tax Tribunal in around May 2018, just in time for the hearing on the 2010/11 Royalty Assessments.132 He had previously worked for SUNAT for almost 18 years, including in the SUNAT division that confirmed the 2010/11 Royalty Assessments on which he was now slated to rule.133 What is more, Judge Mejía Ninacondor had also represented SUNAT in SMCV’s appeal of the 2006/07 Royalty Assessments before the Appeals Court.134

81. On 20 June 2018, SMCV filed a submission requesting that the Tax Tribunal remove Judge Mejía Ninacondor from hearing the case on the 2010/11 Royalty Assessments. In its submission, SMCV emphasized that Judge Mejía Ninacondor failed to meet the most basic requirements of independence and impartiality, as he had litigated on behalf of SUNAT the same issues between the same parties that he was now being called to rule on as a judge.135 But despite the obviously disqualifying conflict of interest, the Tax Tribunal nevertheless denied SMCV’s application in a plenary vote. The Tax Tribunal reasoned that disqualification grounds in Peru must be “interpreted narrowly” and that Judge Mejía Ninacondor was not conflicted.136

82. As with the appeal of the 2008 Royalty Assessments, Chamber No. 1 scheduled a hearing on the appeal of the 2010/11 Royalty Assessments in record time when compared to other Tax Tribunal Chambers. Although the case involving the 2009 Royalty Assessments had been pending for over six years before Chamber No. 2, Chamber No. 1

[Page 27]

quickly scheduled a hearing on the 2010/11 Royalty Assessments within a month of having received SMCV’s appeal.137

83. SMCV was concerned that, as with the appeal of the 2008 Royalty Assessments, Chamber No. 1 would again render a decision first, which Chamber No. 2 would then simply copy-paste. On 20 June 2018, SMCV accordingly requested that in accordance with its well-established practice, the Tax Tribunal decide the appeal of the 2009 Royalty Assessments first since it had been filed first.138 On 18 July 2018, the Tax Tribunal also denied this request and rescheduled the hearing for the 2010/11 Royalty Case to 9 August 2018, the same day that Chamber No. 2 had scheduled the hearing for the 2009 Royalty Case.139

84. On 15 August 2018, Chamber No. 2 issued a decision confirming SUNAT’s 2009 Assessments and rejecting SMCV’s request for a waiver of penalties and interest.140 On 28 August 2018, Chamber No. 1 also confirmed SUNAT’s 2010/11 Royalty Assessments and rejected SMCV’s waiver request.141 Both decisions followed the same reasoning when confirming SUNAT’s Assessments and both copied nearly verbatim the Chamber No. 1 decision confirming the 2008 Royalty Assessments drafted by the assistant to the Tax Tribunal President.142

85. Both decisions also followed the same reasoning when confirming that SMCV was not entitled to a waiver of penalties and interest.143 Despite there clearly being reasonable doubt about the proper interpretation of the Mining Law and Regulations and hence about the scope of SMCV’s stabilization benefits—particularly after a Contentious Administrative Court had agreed with SMCV that the Stability Agreement encompassed the Flotation Plant—both

[Page 28]

Chambers arbitrarily determined that SUNAT’s penalties and interest against SMCV could not be waived.

86. Ignoring the manifest unfairness of charging SMCV extraordinarily punitive penalties and interest when it had always acted in good faith in its interpretation of the Mining Law and Regulations, the Chambers held that SMCV’s Stability Agreement may have been subject to “reasonable doubt,” but purportedly not the Mining Law and Regulations as required under Article 170 of the Tax Code. The Chambers thus effectively ignored both that the Stability Agreement is a form contract drafted by the Government that must incorporate all stability benefits of the Mining Law and Regulations and that the Mining Law and Regulations plainly provide that stability agreements apply to all activities within the relevant concessions or EAU.144

87. Shortly after Chamber No. 1, including Judge Mejía Ninacondor, confirmed the 2010/11 Royalty Assessments and rejected all of SMCV’s claims, the Government implicitly recognized that Judge Mejía Ninacondor should never have heard SMCV’s appeal. On 13 September 2018—that is, only 16 days after Chamber No. 1 issued its decision—the Government amended the Tax Code to require Tax Tribunal judges to abstain from participating in proceedings if they worked for SUNAT within the last 12 months and “directly and actively” participated in the SUNAT proceedings at issue before the Tax Tribunal.145 The Legislative Decree effectively concedes that SMCV’s appeal was not heard by independent and impartial Tax Tribunal judges, but the Tax Tribunal’s decision nevertheless remains in effect.

88. On 28 December 2018 and 3 January 2019, SMCV requested that the Tax Tribunal order SUNAT to recalculate the interest owed by SMCV on the 2009 and 2010/11 Royalty Assessments (Recursos de Queja).146 Pursuant to the Tax Code and decisions by the Peruvian Constitutional Tribunal, in calculating the interest owed by a taxpayer, SUNAT must take account of any delays of more than 12 months in the taxpayer’s proceedings before the Tax Tribunal.147 After the 12-month threshold, SUNAT must apply the Consumer Price Index

(“CPI”) instead of the exorbitant penalty interest rate of 14.4% per year.148 Despite the years-long delays in SMCV’s cases, SUNAT nonetheless applied the exorbitant penalty interest rate of 14.4%, rather than the CPI, to the 2009 and 2010/11 Royalty Assessments.149

89. Faced once again with a fundamentally unfair outcome, SMCV challenged SUNAT’s decisions to the Tax Tribunal. But the Tax Tribunal still did not live up to the law or even to the most basic notions of justice. Within just a few days of receiving SMCV’s challenges, the Tax Tribunal dismissed them both on the pretextual ground that it did not have to consider the merits of SMCV’s challenges because SMCV had requested (under protest) an installment plan with SUNAT for the payment of the 2009 and 2010/11 Assessments.150 In other words, according to the Tax Tribunal, by availing itself of its right under Peruvian law to pay the Assessments through installments, SMCV somehow waived its distinctively different right to a reasonable CPI rate meant to account for the Tax Tribunal’s unjustifiable delays in resolving SMCV’s appeals.

IV. JURISDICTION

90. Pursuant to Article 10.1.1 of the TPA, a tribunal has jurisdiction over “measures adopted or maintained by a Party relating to . . . covered investments.” Pursuant to Article 1.3 of the TPA, a “covered investment” is “with respect to a Party, an investment as defined in Article 10.28 (Definitions), in the territory of an investor of another Party in existence as of the date of entry into force of [the TPA] or established, acquired, or expanded thereafter.”

91. Freeport satisfies each of the requirements because (i) Freeport has a “covered investment” as defined by the TPA, i.e., SMCV and the Cerro Verde mine; (ii) Freeport is an “investor of another Party,” i.e., of the United States; and (iii) Freeport’s investment was “in existence as of the date of entry into force” of the TPA.

A. Freeport Has a Covered Investment under the TPA.

92. Article 10.28 of the TPA defines “investment” as “every asset that an investor owns or controls, directly or indirectly, that has the characteristics of an investment,” and


148 See Ex. CA-14, 22 Jun. 2013 Peruvian Tax Code, Supreme Decree No. 133-2013-EF, Art. 33.

149 See Ex. CE-213, 4 Jan. 2019 [sic] Tax Tribunal Decision, No. 00019-Q-2019; Ex. CE-214, 7 Jan. 2019 Tax Tribunal Decision, No. 00036-Q-2019.

150 See Ex. CE-213, 4 Jan. 2019 Tax Tribunal Complaint Office Decision, No. 00019-Q-2019, 2009 Royalty Assessment; Ex. CE-214, 7 Jan. 2019 Tax Tribunal Complaint Office Decision, No. 00036-Q-2019, 2010/11 Royalty Assessment.

[Page 30]

specifies that “[f]orms that an investment may take include” an enterprise; shares, stock, and other forms of equity participation; concessions and other similar contracts; and other tangible or intangible property. An investment must be made “in [Peru’s] territory” to be considered a covered investment.151

93. Freeport indirectly “owns or controls” SMCV, an “enterprise” constituted under the laws of Peru.152 It also indirectly “owns or controls” the Cerro Verde production unit in the province of Arequipa, Peru, and the Mining and Beneficiation Concessions. Therefore, Freeport’s investments satisfy each element of the definition of “investment” under the TPA.

B. Freeport Qualifies as an Investor under the TPA.

94. Article 10.28 of the TPA defines an “investor of a Party” to include “an enterprise of a Party that attempts through concrete action to make, is making, or has made an investment in the territory of another Party.”

95. Freeport is a United States entity organized under the laws of the State of Delaware.153 Thus, Freeport qualifies as an “enterprise of a Party” under the TPA. Further, as discussed above, Freeport’s investments were “made” in the territory of Peru—SMCV is a Peruvian entity and the Cerro Verde mine and Concessions are all in Peru.154

C. Freeport’s Investment Was in Existence When the TPA Entered into Force.

96. Finally, pursuant to Article 1.3, the TPA applies not only to investments “established, acquired, or expanded” after the entry into force, but also to investments “in existence as of the date of entry into force” of the TPA. The TPA entered into force on 1 February 2009.155

97. In 1999, Freeport’s predecessor (Phelps Dodge) indirectly acquired a majority of SMCV and the Cerro Verde mining operations.156 In 2007, Phelps Dodge merged with

[Page 31]

Freeport, which became the indirect majority owner of SMCV.157 Thus, Freeport’s investment was “in existence” as of February 2009 and qualifies for protection under the TPA.

98. The TPA further states in Article 10.1.3 that “for greater certainty, this Chapter does not bind any Party in relation to any act or fact that took place or any situation that ceased to exist before the date of entry into force of this Agreement.” Freeport’s claims in this arbitration are all based on acts by Peru—including the first Tax Tribunal decisions confirming the 2006/07 and 2008 Assessments in May 2013—that took place after February 2009, the date of the TPA’s entry into force.

V. CONSENT TO ICSID ARBITRATION

99. Article 25 of the ICSID Convention provides that the Jurisdiction of the Centre shall extend to “any legal dispute arising directly out of an investment, between a Contracting State . . . and a national of another Contracting State, which the parties to the dispute consent in writing to submit to the Centre.”

100. All of these elements are satisfied here. First, as described above in Section I (Introduction) and Section III (Background), Freeport submits through this Notice of Arbitration a legal dispute arising directly out of its investments in the Cerro Verde mine. Second, the dispute is between Peru, an ICSID Contracting State,158 and Freeport, a national of the United States, another ICSID Contracting State,159 acting on its own behalf and that of SMCV. Third, Peru consented in writing to submit the dispute to the Centre in the TPA. Specifically, Article 10.16.3 of the TPA provides that investors may submit claims “under the ICSID Convention and the ICSID Rules,” provided that both Peru and the United States are parties to the ICSID Convention.160 Article 10.17 further provides that Peru “consents to the submission of a claim to arbitration under this Section in accordance with” the TPA and that such consent “shall satisfy the requirements of Chapter II of the ICSID Convention (Jurisdiction of the Centre).”

VI. MERITS

102. Peru has breached both the Stability Agreement and the TPA.

103. First, Peru breached the Stability Agreement and its contractual obligation to provide SMCV with fiscal and administrative stability by confirming the 2009, 2010/11, 4Q 2011, 2012, and 2013 Royalty Assessments and the Tax Assessments listed in Annex A and Annex B hereto based on the Royalty Law and other “modifications or new rules”161 that the Government issued while the Stability Agreement remained in force.

104. Second, Peru breached Articles 10.5 (Minimum Standard of Treatment) and 10.4 (Most Favored Nation Treatment) of the TPA by (i) failing to grant SMCV a fair hearing before the Tax Tribunal and by denying SMCV effective means to enforce its rights in the 2009, 2010/11, 4Q 2011, 2012, and 2013 Royalty Cases and the Tax Cases listed in Annex A and Annex B; (ii) arbitrarily refusing to waive SUNAT’s extraordinarily punitive penalties and interest in the 2006/07, 2008, 2009, 2010/11, 4Q 2011, 2012, and 2013 Royalty Cases and the Tax Cases listed in Annex A and Annex B; and (iii) arbitrarily refusing to fully repay SMCV the GEM overpayments for the 4Q 2011 to 3Q 2012 time period.

A. Peru Breached the Stability Agreement.

105. Article 10.16.1 of the TPA permits an “investor of a Party” to submit to arbitration a claim that the other Party has breached an “investment agreement” with an enterprise that the investor “owns or controls directly or indirectly.”162

106. As explained in Section IV (Jurisdiction) above, Freeport is an investor of the United States and the Stability Agreement is an “investment agreement” as defined in Article 10.28 of the TPA163 because it grants rights to SMCV, a “covered investment” of Freeport,


161 Ex. CE-12, 1998 Stability Agreement, Clause 9.5.

162 Ex. CA-10, TPA, Arts. 10.16 and 10.28 (defining the terms “Claimant” and “Respondent” used in Art. 10.16).

163 Ex. CA-10, TPA, Art. 10.28 (“investment agreement means a written agreement between a national authority of a Party and a covered investment or an investor of another Party, on which the covered investment or the investor relies in establishing or acquiring a covered investment other than the written agreement itself, that grants rights to the covered investment or investor: (a) with respect to natural resources that a national authority controls, such as for their exploration, extraction, refining, transportation, distribution, or sale; (b) to supply services to the public on behalf of the Party, such as power generation or distribution, water treatment or distribution, or

[Page 33]

“with respect to ... the exploration, extraction, refining, transportation, distribution, or sale” of “natural resources”—namely, the guarantee of a stable administrative and tax regime with respect to the investments in the Mining and Beneficiation Concessions. Further, Freeport and SMCV relied on the Stability Agreement “in establishing or acquiring a covered investment.” Freeport relied on the Stability Agreement in acquiring SMCV’s shares and Freeport and SMCV relied on the Stability Agreement in making their investments in the Cerro Verde mine including, among other investments, the Leaching and the Flotation Plant. Freeport also indirectly “owns or controls” SMCV, a Peruvian entity that is party to an investment agreement with the Peruvian Government.164

107. Freeport is thus entitled to submit to arbitration on behalf of SMCV Peru’s breaches of the Stability Agreement.165

108. Peru breached the Stability Agreement and its contractual obligation to (i) provide fiscal and administrative stability to SMCV;166 (ii) exempt SMCV from the application of any new laws or regulations that “directly or indirectly, denaturalize[d] the guarantees provided” by the Stability Agreement;167 and (iii) protect SMCV from “any encumbrance or obligation that could represent reduction of its availability of cash”168 when the Tax Tribunal confirmed the 2009, 2010/11, and 4Q 2011 Royalty Assessments and the Tax Assessments listed in Annex A.169 Peru also breached the Stability Agreement when SUNAT rejected SMCV’s reconsideration requests of the 2012 and 2013 Royalty Assessments and the Tax Assessments listed in Annex B because in view of the Tax Tribunal’s consistent failure to act independently and impartially with regard to SMCV’s claims, as further explained in

168 Id., Clause 10.2; see also Clause 9.4, allowing SMCV to keep its accounting in dollars; and Clause 13 providing that the provisions referenced in the Stability Agreement are the ones in force at the time of the approval of the Feasibility Study.

169 For clarity, Peru also breached the 1998 Stability Agreement when the Tax Tribunal confirmed the 2006/07 and 2008 Royalty Assessments in May 2013. However, since more than three years have passed since the Tax Tribunal notified SMCV of its decisions, Freeport is not submitting claims for breach of the 1998 Stability Agreement with regard to the 2006/07 and 2008 Assessments. See Article 10.18.1 of the TPA.

[Page 34]

Section VI(B) below, it had become at that point entirely futile for SMCV to appeal those Assessments further before the Tax Tribunal.

109. Peru’s novel and restrictive position that stabilization benefits are limited to the investments set forth in the feasibility study submitted to the Government to obtain the stability agreement and that Clause 1 of the Stability Agreement limits the scope of SMCV’s stabilization benefits to the minerals processed through leaching, finds no support in Peru’s own laws and practice or the plain terms of the Stability Agreement.

110. First, Peru’s novel and restrictive position that SMCV’s stabilization benefits must be distinguished based on their processing method, i.e., on whether SMCV uses leaching or flotation to process the minerals extracted under its sole Mining Concession, cannot be reconciled with the manner in which Royalty payments are assessed under the Royalty Law. The Royalty Law imposes royalties on the extraction of minerals. How such minerals are then processed is entirely irrelevant for purposes of calculating any royalties due to the Government. Specifically, Article 2 of the Royalty Law provides that mining companies shall pay royalties as consideration for the “exploitation of metallic and non-metallic mineral resources.”170 In turn, Article 8 of the Mining Law states that “exploitation is the activity of extracting minerals”171 and Article 4 of the Royalty Law Regulations states that “payment of the mining royalty” shall be calculated based on “the mineral extracted while operating mining concessions.”172

111. Second, there is no support in the Mining Law and Regulations for Peru’s novel and restrictive position that stabilization benefits are limited to the investments set forth in the feasibility study submitted to obtain the stability agreement. On the contrary, the Mining Law and Regulations provide that stabilization benefits attach to the activities performed by the “title holder of the mining activity” either within a particular concession or within a particular EAU, without any distinction between different processing methods.173 For instance, Article 82 of the Mining Law provides that the purpose of stability agreements is “to promote investment and facilitate the financing of mining projects . . . regarding one or more Economic Administrative Units,” which include the mining concessions that form an EAU (like SMCV’s Mining and Beneficiation Concessions) and “all other assets that form part of a single

[Page 35]

production unit”174 (such as the Flotation Plant). Similarly, Article 83 of the Mining Law provides that stability benefits “extend exclusively to the activities of the mining company in whose favor the investment is made,”175 again without limitation to a particular subset of activities within the same concession or EAU.176

112. Moreover, Article 22 of the Regulations specifically provides that stability benefits apply to a mining company “exclusively for investments it makes in the concessions or Economic Administrative Units.”177 And Article 25 of the Regulations expressly recognizes that a mining company may “expand[] its facilities or [make] new investments that benefit from the contractual stability guarantee.” If stabilization benefits cover only the initial investments included in the feasibility study submitted to the Government for purposes of obtaining stabilization benefits, as Peru now claims, then it would make no sense for Article 22 to reference the mining company’s investments within its concessions or EAU (rather than investments in its feasibility study), or for Article 25 to expressly reference “new” or “expand[ed]” investments also falling within the “contractual stability guarantee.”

113. Third, under the Stability Agreement, the scope of the stabilization benefits likewise extended to SMCV’s activities within its Mining and Beneficiation Concessions without any limitations. In fact, the scope of SMCV’s stabilization benefits under the Stability Agreement cannot be different from that under the Mining Law and Regulations. Pursuant to Article 86 of the Mining Law, the Stability Agreement was a form contract drafted by the Government that incorporated all of the stabilization benefits granted by the Mining Law and Regulations. Article 86 expressly states that “the contracts that guarantee [stability benefits] are form contracts based on templates prepared by the Ministry of Energy and Mines. Such contracts must incorporate all guarantees established under this Section” of the Mining Law (i.e., the Section titled “Tax Stability Regime”).178

114. Clause 1.1 of the Stability Agreement accordingly provided that SMCV requested stabilization benefits “in relation with the investment in its concession Cerro Verde

See also id., Article 2 (holding that the guaranteed benefits “are applied as of right to all mining activity concessionaires . . . that exercise mining activity in a concession or in concessions grouped in an Economic Administrative Unit” “[w]hen the natural or legal person is the holder of several concessions or Economic-Administrative Units.”)

178 See Ex. CA-01, 3 Jun. 1992 General Mining Law, Supreme Decree No. 014-92-EM, Art. 86.

[Page 36]

No. 1, No. 2, and No. 3,”179 and Clause 3 and Annex I provided that the stabilization benefits were “circumscribed” to SMCV’s Mining and Beneficiation Concessions.180 In turn, Clauses 9 and 10, which define and describe the stabilization benefits, provide that those benefits are granted to “the owner” (i.e., SMCV) without any limitations based on how the Cerro Verde minerals would be processed.181

115. Moreover, when entering into the Agreement, the Government was fully aware that (i) Cerro Verde’s leachable reserves would be exhausted by 2014 and it would thus be necessary to build processing facilities for processing the primary sulfides;182 and (ii) in the 1994 Share Purchase Agreement, the Government imposed on SMCV the obligation to install new mill and flotation facilities for processing primary sulfides.183 As stated above, the Government accordingly approved SMCV’s proposal to invest US$800 million for the construction of the Flotation Plant and also approved through a Resolution the extension of SMCV’s Beneficiation Concession to include the Flotation Plant.184

116. Fourth, Peru’s novel and restrictive position is inconsistent with its own earlier statements and practice, including in presentations to the Peruvian Congress by high Government officials confirming that SMCV and other mining companies with stability agreements would be exempted from paying royalties under the Royalty Law while their agreements remained in force, as explained in Section III (Background) above.185

117. Finally, Peru’s novel and restrictive position makes no commercial or practical sense. It results in a single mining concession having multiple fiscal regimes even though


179 See Ex. CE-12, 1998 Stability Agreement, Clause 1.1.

180 Id., Annex I.

[Page 37]

Peruvian law and regulations provide no guidance whatsoever about how a mining company is meant to split its activities within a single concession into stabilized and non-stabilized investments. In fact, Peru’s position is so nonsensical that not even SUNAT has been able to properly implement it. One salient example is the 2013 Complementary Mining Pension Fund Case, which is included in Annex B. Through Law No. 29741 of 2011, the Government created a new obligation for mining companies to pay 0.5% of their yearly net income to a Mining Pension Fund. Since Law No. 29741 was passed while the Stability Agreement was in force, SMCV should have been exempted from making any such payments. Under Peru’s novel and restrictive position, SMCV would have to pay 0.5% of its yearly net income to the Fund, but only with regard to its “non-stabilized” net income (i.e., the Flotation Plant-related income). Unsurprisingly, however, SUNAT was unable to determine how to assess SMCV based only on its Flotation Plant-related income. Instead, SUNAT simply imposed the payments on the entirety of SMCV’s net income, which even under the Government’s own novel and restrictive interpretation of the scope of SMCV’s stabilization benefits is a clear breach of the Stability Agreement.

118. Peru’s novel and restrictive position also flouts the stabilization regime’s very purpose, which the Mining Law expressly defines as “promot[ing] investment and facilitat[ing] the financing of mining projects.”186 That purpose can be achieved only if, as the Mining Law provides, stabilization benefits extend to all investments and activities within the covered concessions during the life of the stability agreement.187 Stabilization benefits that are not artificially limited to specific investments as set forth in the feasibility study better reflect the nature of the industry and better provide mining companies with the clarity and predictability that they need to invest and attract financing for their large and long term investments. Peru’s novel and restrictive interpretation of the scope of stabilization benefits strongly discourages investors from making additional capital investments to increase the mine’s productivity or to exploit minerals that cannot be processed in the existing facilities.

B. Peru Breached Articles 10.5 (Minimum Standard of Treatment) and 10.4 (Most Favored Nation Treatment) of the TPA.

119. Peru breached Articles 10.5 and 10.4 of the TPA when the Tax Tribunal collaborated with SUNAT to uphold SUNAT’s Royalty and Tax Assessments in violation of SMCV’s due process rights, and also by arbitrarily failing to waive SUNAT’s extraordinarily punitive penalties and interest despite SMCV being entitled under Peruvian law to such a


186 Ex. CA-01, 3 Jun. 1992 General Mining Law, Supreme Decree No. 014-92-EM, Art. 82.

187 Ex. CA-01, 3 Jun. 1992 General Mining Law, Supreme Decree No. 014-92-EM, Arts. 82, 83, 86.

[Page 38]

waiver. Peru also breached Articles 10.5 and 10.4 of the TPA when SUNAT arbitrarily refused to fully repay SMCV GEM overpayments even though SMCV was entitled to those repayments under the GEM Agreement and Peruvian law.

120. Article 10.5 of the TPA (Minimum Standard of Treatment) provides in pertinent part:

1. Each Party shall accord to covered investments treatment in accordance with customary international law, including fair and equitable treatment and full protection and security.

2. For greater certainty, paragraph 1 prescribes the customary international law minimum standard of treatment of aliens as the minimum standard of treatment to be afforded to covered investments. The concepts of “fair and equitable treatment” and “full protection and security” do not require treatment in addition to or beyond that which is required by that standard, and do not create additional substantive rights. The obligation in paragraph 1 to provide . . . “fair and equitable treatment” includes the obligation not to deny justice in criminal, civil, or administrative adjudicatory proceedings in accordance with the principle of due process embodied in the legal systems of the world […].188

121. Moreover, Freeport here is entitled to an even more protective standard, through the operation of the TPA’s “Most Favored Nation Treatment” Clause. That clause— Article 10.4 of the TPA—ensures that U.S. investors in Peru will be treated no less favorably than investors of any other state, and provides:

1. Each Party shall accord to investors of another Party treatment no less favorable than that it accords, in like circumstances, to investors of any other Party or of any non-Party with respect to the establishment, acquisition, expansion, management, conduct, operation, and sale or other disposition of investments in its territory.

2. Each Party shall accord to covered investments treatment no less favorable than that it accords, in like circumstances, to investments in its territory of investors of any other Party or of any non-Party with respect to the establishment, acquisition, expansion, management, conduct, operation, and sale or other disposition of investments.189


188 Ex. CA-10, TPA Art. 10.5.

189 Ex. CA-10, TPA, Art. 10.4.

[Page 39]

122. By operation of that provision, Freeport is entitled to avail itself of the Protocol to the Peru-Italy Treaty on the Promotion and Protection of Investments of 1994, in which Peru agreed to provide Italian investors “effective means of asserting claims and enforcing rights with respect to investments and authorizations related to them and investment agreements.”190 Accordingly, pursuant to Article 10.4 of the TPA, Peru must provide Freeport with “effective means” to enforce their rights.191 The obligation to provide effective means consists both of a negative obligation to avoid interfering with the investor's exercise of rights, and a positive obligation to provide effective means to assert and enforce those rights.192

1. Peru's Violation of SMCV's Due Process Rights.

123. Peru violated SMCV's due process rights in breach of the minimum standard of treatment and effective means clause when the Tax Tribunal collaborated with SUNAT to confirm the 2009 and 2010/11 Royalty Assessments.

124. While SMCV was afforded the opportunity to present written and oral submissions to the Tax Tribunal in its appeals of the Royalty Assessments, it never had a fair chance to persuade the Tax Tribunal judges of its position. As the facts set forth in Section(III) (D) (Background) above show, the Tax Tribunal judges did not decide SMCV's cases independently and impartially but rather collaborated with SUNAT to ensure that the Government would prevail. This is demonstrated by, among other things, the fact that:


190 Ex. CA-03, Peru-Italy Treaty on the Promotion and Protection of Investments, 5 May 1994, Protocol ¶ 2(c) (unofficial translation).

191 Ex. CA-12, White Industries Australia Ltd. v. India, UNCITRAL, Final Award of 30 Nov 2011, ¶ 11.2.1 (importing the effective means clause from a third-party treaty through the MFN provision).

192 Ex. CA-11, Chevron v. Ecuador, UNCITRAL, Partial Award on the Merits of 30 Mar. 2010, ¶ 248. See also Ex. CA-12, White Industries Australia Ltd. v. India, UNCITRAL, Final Award of 30 Nov 2011, ¶ 11.3.2(b) (Effective means require “both that the host State establish a proper system of laws and institutions and that those systems work effectively in any given case.”).

[Page 40]

125. Given that the Tax Tribunal has consistently failed to act independently and impartially with regard to SMCV's claims, it had become entirely futile for SMCV to appeal the 2012 and 2013 Royalty Assessments to the Tax Tribunal, or any of the Tax Assessments listed in Annex B. Moreover, as a result of the Tax Tribunal's consistent disregard for the most basic norms of due process, Freeport lacked any effective means to enforce its rights before the Tax Tribunal also with regard to the 4Q 2011 Royalty Assessments and the Tax Assessments listed in Annex A.

2. Peru's Arbitrary and Grossly Unfair Imposition of Penalties and Interest.

126. Peru also violated its obligations under the minimum standard of treatment and effective-means clauses when (i) the contentious administrative courts (specifically, the Appellate Court and the Supreme Court) arbitrarily refused to waive SUNAT's extraordinarily punitive penalties and interest on the 2006/07 and 2008 Royalty Assessments; (ii) the Tax Tribunal arbitrarily refused to waive SUNAT's extraordinarily punitive penalties and interest on the 2009, 2010/11, and 4Q 2011 Royalty Assessments and the Tax Assessments listed in Annex A; and (iii) SUNAT arbitrarily refused to waive its extraordinarily punitive penalties and interest on the 2012 and 2013 Royalty Assessments and the Tax Assessments listed in Annex B.

127. Under Peruvian law, the purpose of imposing punitive penalties and interest of up to 14.4% per year is to penalize taxpayers that unlawfully flout their obligations to pay taxes and deter future wrongdoing. However, in circumstances where the royalty or tax assessments are based on a legal provision that is subject to reasonable doubt, the Government must waive

[Page 41]

such penalties and interest.193 This ensures that taxpayers are not penalized for exercising their right to challenge assessments that are based on legal provisions subject to reasonable doubt.

128. Specifically, Article 170 of the Peruvian Tax Code and Article 12 of Law 28969 provide that penalties and interest are not applicable and must be waived when the proper interpretation of the applicable legal provision on which the royalty or the tax assessment is based is subject to reasonable doubt.194

129. Peru has never once disputed that SMCV's decision not to pay Royalties or Taxes for its Flotation Plant-related activities was made in good faith. Peru also cannot seriously dispute that the scope of stabilization benefits under the Mining Law and Regulations was subject to reasonable doubt: (i) the Contentious-Administrative Courts hearing SMCV's appeals in the 2006/07 and 2008 Royalty Cases reached conflicting results, with the first instance Court hearing the appeal of the 2008 Royalty Assessments upholding SMCV's position that the Stability Agreement covers the entirety of SMCV's activities in its Mining Concessions;195 (ii) as explained in Section VI(A) above, neither the Royalty Law nor the Mining Law and Regulations support Peru's novel and restrictive position that stabilization benefits are limited to the investments set forth in the feasibility study submitted to obtain the stability agreement. On the contrary, the Royalty Law, and the Mining Law and Regulations all expressly support SMCV's position that stabilization benefits attach to a particular concession or EAU, without any distinction between processing methods;196 (iii) the Stability Agreement expressly states that it applies to SMCV's Mining and Beneficiation Concessions, which include both the Leaching Facilities and Flotation Plant;197 (iv) several Government officials confirmed that SMCV and other mining companies were exempted from paying royalties under the Royalty Law because of stability agreements with the Government;198 (v)


193 See Ex. CA-04, Peruvian Tax Code, Art. 180 (providing that “[t]he Tax Administration shall apply, for the commission of violations, the penalties consisting of fines...”).

[Page 42]

the Tax Tribunal issued a Resolution in 2011 acknowledging that stabilization benefits extend to all investments within an EAU;199 (vi) in a clear reflection of the recognized uncertainty, President Vizcarra submitted a draft law to Congress in 2018 that sought to "modify" the Mining Law "in order to make the interpretation of stabilization benefits uniform" and "to include preexisting investments within the scope of stabilization benefits” provided that they are included in the feasibility study submitted to the Government for purposes of obtaining such benefits.200 While the President's efforts did not come to fruition, the draft law is a clear recognition from the Peruvian Government that the interpretation of the scope of stabilization benefits is not “uniform” and hence, at a minimum, subject to reasonable doubt;201 and (vii) the Government accepted, or at the very least acquiesced in, SMCV's interpretation of the scope of the stabilization benefits when it accepted GEM payments in lieu of royalty payments.202

130. In these circumstances, the Government was under a clear obligation to waive SUNAT's extraordinarily punitive penalties and interest. The Government has nevertheless arbitrarily refused to waive the penalties and interest and thereby has penalized SMCV for defending its rights by challenging in good faith SUNAT's Royalty and Tax Assessments that SMCV firmly believes violate the Government's contractual and statutory obligation to provide fiscal and administrative stability to SMCV. The Government has done so on spurious and arbitrary grounds.

131. Specifically, in the 2006/07 and 2008 Royalty Cases, the Contentious Administrative Courts arbitrarily upheld the Tax Tribunal's decision that SMCV lost its right to a waiver of penalties and interest by not including a waiver request in its appeals to the Tax Tribunal.203 That ruling stands in stark contrast to decisions issued by the Tax Tribunal in cases brought by other taxpayers, where the Tax Tribunal has accepted waiver requests from other

taxpayers that were submitted after the corresponding appeal decisions had been issued. Such inconsistent treatment is a hallmark of arbitrariness.204

132. Further, in the 2009, 2010/11, and 4Q 2011 Royalty Cases and in certain Tax Cases included in Annex A,205 the Tax Tribunal arbitrarily held that reasonable doubt existed only over the scope of the Stability Agreement and not over the Mining Law and Regulations as required by Article 170 of the Tax Code.206 But as explained above, pursuant to Article 86 of the Mining Law, the Stability Agreement was a “form contract[] based on templates prepared by the Ministry of Energy and Mines” and it “incorporate[s] all guarantees established under” the Mining Law.207 Moreover, the Supreme Court itself based its decision upholding the 2008 Royalty Assessments, in part, on its interpretation of the Mining Law and Regulations.208

133. As a result of the Government's arbitrary refusal to waive penalties and interest, as it was required to do under its own laws, the penalties and interest assessed against SMCV today account for more than 60% of Freeport's damages.

134. To make matters worse, the Government's arbitrary and grossly unfair conduct does not stop there. Not satisfied with the hundreds of millions of dollars that it unlawfully imposed on SMCV in penalties and interest, the Government also arbitrarily refused to take account of the Tax Tribunal's excessive delays in resolving SMCV's appeals against the 2009 and 2010/11 Royalty Assessments even though it was mandated to do so under Peruvian law. As explained in paragraphs 88-89 above, pursuant to the Tax Code and decisions by the Peruvian Constitutional Tribunal, in calculating the interest owed by a taxpayer, SUNAT must take account of any delays of more than 12 months in the taxpayer's proceedings before the

Tax Tribunal.209 After the 12-month threshold, SUNAT must apply the CPI rate of around 2% instead of the exorbitant penalty interest rate of 14.4% per year.210 Despite the years-long delays in SMCV's appeals against the 2009 and 2010/11 Royalty Assessments, SUNAT nonetheless applied the exorbitant 14.4% rate, rather than the CPI, to the 2009 and 2010/11 Royalty Assessments. The Tax Tribunal arbitrarily upheld SUNAT's decision on the specious grounds that, by applying (under protest) for an installment payment plan for the 2009 and 2010/11 Royalty Assessments, SMCV would have waived its right to a reasonable CPI rate.211

3. Peru's Arbitrary and Grossly Unfair Refusal to Reimburse GEM Overpayments.

135. Peru further violated SMCV's due process rights in breach of the minimum standard of treatment and effective-means clauses when SUNAT arbitrarily refused to reimburse GEM overpayments for the time period 4Q 2011 to 3Q 2012.

136. Under the GEM Agreement and Peruvian law, SMCV had to make GEM payments to the Government provided that it was exempted from paying royalties—mining companies that had to pay royalties were not subject to the GEM.212 Accordingly, since the Stability Agreement exempted SMCV from making any royalty payments, SMCV paid the GEM to the Government for the time period 4Q 2011 to 4Q 2013.213 Shortly after the Supreme Court dismissed SMCV's appeal on the 2008 Royalty Assessments, SMCV submitted reimbursement requests to SUNAT claiming that SMCV cannot be subject to paying both GEM and the royalties for its Flotation Plant-related activities.214 SMCV submitted these requests while fully reserving its rights under the Stability Agreement, the TPA, and international law. SUNAT rightly agreed with SMCV and repaid US$76 million including interest. However,

[Page 45]

SUNAT then arbitrarily refused to repay the remaining overpayments amounting to US$66 million including interest by conveniently claiming that the statute of limitations under Peruvian law for reimbursements ran from the time of SMCV's GEM payments and not, as it should have, from the date of the Supreme Court's decision, which confirmed that SMCV had to pay the 2008 Royalty Assessments. SUNAT thus effectively imposed both GEM payments and royalties on SMCV.215

VII. DAMAGES

137. Peru's breaches of the Stability Agreement and the TPA have caused, and are continuing to cause, Freeport significant loss and damage. In particular, SMCV has been forced to pay, and is still paying to the Peruvian Government, unlawful Royalty and Tax Assessments that together with SUNAT's extraordinarily punitive penalties and interest are presently estimated to exceed US$1 billion. Accordingly, as compensation for the harm resulting from Peru's breaches, Freeport seeks damages presently estimated to exceed US$1 billion, plus applicable interest.

138. For purposes of this Notice of Arbitration, Freeport has estimated its "approximate amount of damages"216 by applying an exchange rate of 3.317 Soles to 1 U.S. dollar to all Assessment values. Freeport, however, reserves the right to amend the applicable exchange rate in the course of this proceeding to ensure that Freeport's requested damages properly wipe out the effects of Peru's breaches of the Stability Agreement and the TPA.

VIII. PROCEDURAL REQUIREMENTS

139. The TPA sets out specific requirements that must be satisfied before submitting claims to arbitration—all of which have been satisfied by Freeport and SMCV.217

140. First, Article 10.15 of the TPA requires that “the claimant and the respondent initially seek to resolve the dispute through consultation and negotiation." Freeport and SMCV made considerable efforts to fairly resolve the dispute with the Government, including in numerous meetings with former Presidents and President Vizcarra himself, former and current


215 Ex. CE-218, 4 Mar. 2019 SUNAT Resolution No. 012-180-0018640/SUNAT.

216 See Ex. CA-10, TPA, Article 10.16.2(d).

217 See Ex. CE-260, 27 Feb. 2020, Payment Certificate of Lodging Fee.

[Page 46]

Ministers, other high-level Government officials, and most recently, the Peruvian Special Commission that Represents Peru in International Investment Disputes. Freeport has therefore complied with Article 10.15 of the TPA.

141. Second, Article 10.16.2 of the TPA requires submitting claims to arbitration "at least 90 days" after filing the Notice of Intent. On 26 November 2019, Freeport delivered a Notice of Intent to Peru specifying its name and address; the provisions of the Stability Agreement and the TPA that Peru breached; the legal and factual basis for its claims; and the relief sought and approximate amount of damages claimed.218 More than 90 days have since passed. Freeport has therefore complied with Article 10.16.2 of the TPA.

142. Third, Article 10.16.3 of the TPA requires submitting claims to arbitration when "six months have elapsed since the events giving rise to the claims." As described above in Section III (Background) and Section IV (Merits), more than six months have passed since the events giving rise to Peru's breaches of the Stability Agreement and the TPA. Freeport has therefore complied with Article 10.16.3 of the TPA.

143. Fourth, Article 10.18.1 of the TPA requires that no “more than three years" may “have elapsed from the date on which the claimant first acquired, or should have acquired, knowledge of the breach [and that it] has incurred loss or damage." Freeport first “acquired knowledge" of Peru's breaches of the Stability Agreement and the TPA, and knowledge that it "incurred loss or damage,” within the last three years of delivering this Notice of Arbitration to the ICSID Secretary-General.

144. Specifically, as explained in Section IV(A) (Merits), Freeport "acquired knowledge" of Peru's breaches of the Stability Agreement when SMCV was notified of each of the Tax Tribunal decisions confirming SUNAT's Royalty and Tax Assessments (or when SUNAT rejected SMCV's reconsideration requests after further recourse to the Tax Tribunal had become futile). Further, Freeport acquired knowledge of having “incurred loss or damage" only when SMCV was notified of the Tax Tribunal's and SUNAT's decisions because that is when each of SUNAT's Assessments became final and binding on SMCV under Peruvian law. All of those decisions were notified to SMCV within the last three years.219 Freeport has

CE-188, 15 Aug. 2018 Tax Tribunal Decision, No. 06141-2-2018, notified to SMCV on 28 Sept. 2018 (confirming SUNAT's rejection of SMCV's reconsideration request over the 2009 Royalty Assessments); Ex. CE-194, 28 Aug. 2018 Tax Tribunal Decision, No. 06575-1-2018, notified to SMCV on 18 Sept. 2018 (confirming SUNAT's rejection of SMCV's

[Page 47]

therefore complied with Article 10.18.1 of the TPA with regard to its claims for breach of the Stability Agreement.

145. As explained in Section IV(B) (Merits), Freeport similarly "acquired knowledge" of Peru's breaches of the TPA and knowledge that it "incurred loss or damage" when (i) SMCV was notified of the arbitrary decisions refusing to waive SUNAT's extraordinarily punitive penalties and interest that constitute a breach of the TPA; (ii) the Tax Tribunal notified SMCV of its decisions confirming SUNAT's 2009 and 2010/11 Royalty Assessments and SMCV received access to the case files showing that the Tax Tribunal had violated SMCV's due process rights in breach of the minimum standard of treatment and effective means clause; (iii) the Tax Tribunal notified SMCV of its decisions confirming the 4Q 2011 Royalty Assessments and the Tax Assessments listed in Annex A in violation of the minimum standard of treatment and effective means clause; (iv) SUNAT notified SMCV of its decisions confirming the 2012 and 2013 Royalty Assessments and the Tax Assessments listed in Annex B in violation of the minimum standard of treatment and effective means clause; and (v) SUNAT notified SMCV of its decision arbitrarily denying part of the GEM reimbursements. Those decisions were all notified to SMCV within the last three years (except in those proceedings where SUNAT or the Tax Tribunal did not issue a decision prior to Freeport withdrawing its claims pursuant to Article 10.18.2(b) of the TPA, where Freeport similarly acquired knowledge of Peru's breaches and that it “incurred loss or damage" within the last three years).220 Freeport has therefore complied with Article 10.18.1 of the TPA with regard to its claims for breach of the TPA.

146. Fifth, Article 10.18(2)(b) of the TPA requires that Freeport and SMCV each waive their "right to initiate or continue before any administrative tribunal or court under the law of any Party, or other dispute settlement procedures, any proceeding with respect to any measures alleged to constitute a breach” of the TPA. Freeport and SMCV have each duly signed Waiver Declarations pursuant to the terms of Article 10.18(2)(b), as evidenced in

CE-269, 18 Nov. 2019 Tax Tribunal Decision, No. 10574-9-2019, notified to SMCV on 4 Dec. 2019 (confirming SUNAT's rejection of SMCV's reconsideration request over the 4Q 2011 Royalty Assessments); Ex. CE-215, 11 Jan. 2019 SUNAT Rejects SMCV Request, 2012 Royalty Assessment, notified to SMCV on 23 January 2019; Ex.

CE-218, 4 Mar. 2019 SUNAT Resolution No. 012-180-0018640/SUNAT.

[Page 48]

Ex. CE-267 and Ex. CE-240.221 Moreover, as an abundance of caution, SMCV has voluntarily withdrawn from each and every proceeding in Peru related to the Stability Agreement, as evidenced in the withdrawal requests submitted as Ex. CE-241 to Ex. CE-259.222 Freeport and SMCV have therefore complied with Article 10.18(2)(b) of the TPA.

147. Sixth, Article 10.18(4)(a) of the TPA requires that no claim be submitted for a breach of an investment agreement if the claimant or enterprise that it owns or controls directly or indirectly "has previously submitted the same alleged breach to an administrative tribunal or court [of Peru] or to any other binding dispute settlement procedure." As explained above in Section VI (Merits), the Stability Agreement is an investment agreement under the TPA. Neither Freeport nor SMCV has submitted contractual claims for breach of the Stability Agreement to Peru's administrative tribunals, courts, or any other applicable dispute settlement procedure. Rather, SMCV submitted administrative claims challenging the validity of the Tax Tribunal's decisions and SUNAT's Assessments under the Mining Laws and Regulations. Freeport has therefore complied with Article 10.18(4)(a) of the TPA.

148. Seventh, Annex 10-G of the TPA provides that a U.S. investor may not submit a treaty claim to arbitration if the claimant or enterprise that it owns or controls directly or indirectly "has alleged that breach of an obligation under [the TPA's substantive treaty protections] in proceedings before a court or administrative tribunal." Neither Freeport nor

[Page 49]

SMCV has submitted any treaty claims to Peru's administrative tribunals, courts, or any other applicable dispute settlement procedure. Freeport has therefore complied with Annex 10-G of the TPA.

149. Finally, pursuant to Article 10.18.2(a) of the TPA, Freeport and SMCV hereby consent "in writing to arbitration in accordance with the procedures set out” in the TPA, including pursuant to Article 10.19 the procedures for Selection of Arbitrators. Further, Freeport and SMCV have undertaken all necessary internal actions to authorize their agents, counsel, and advocates to file this Notice of Arbitration.223

IX. CONSTITUTION OF THE TRIBUNAL

150. Article 10.19 of the TPA provides that “the tribunal shall comprise three arbitrators, one arbitrator appointed by each of the disputing parties and the third, who shall be the presiding arbitrator, appointed by agreement of the disputing parties. Article 10.16.6(a) of the TPA further provides that “the claimant shall provide with the notice of arbitration (a) the name of the arbitrator that the claimant appoints."

151. Freeport hereby appoints Professor Dr. Guido Santiago Tawil as its party-appointed arbitrator. Professor Tawil's contact details are as follows:

Annex A

TAX ASSESSMENTS RELATING TO THE STABILITY AGREEMENT THAT SMCV APPEALED BEFORE THE TAX TRIBUNAL

Government's Violations of the Stability Agreement Amount (USD) Procedural Status
Income Tax 2006

In the Fine Resolutions dated 26 May 2011, SUNAT determined that:

  1. SMCV should have kept the Flotation Plant accounting in Peruvian soles.1 Under the 1998 Stability Agreement SMCV was authorized to keep its accounting in US dollars.
  2. SMCV should have kept separate accounting for the Flotation Plant and Leaching Facility.2 Under the 1998 Stability Agreement SMCV was not required to have separate accounting for each investment because both are part of SMCV’s only Beneficiation Concession.

In the Assessment dated 27 May 2011, SUNAT determined that:

  1. SMCV should not have deducted the depreciation of fixed assets of the Flotation Plant.3 Under the 1998 Stability Agreement SMCV had the right to deduct the depreciation of fixed assets of the Flotation Plant and Leaching Facility.
  2. SMCV did not have the right to include an additional depreciation of approximately US$2 million in the Flotation Plant’s amended tax return because it was not recorded in the accounting books.4 Under the 1998 Stability Agreement this requirement did not apply.

In the Fine Resolution dated 27 May 2011, SUNAT determined that:

  1. SMCV had to pay a fine because it failed to report income in its tax return based on SUNAT’s findings in the Assessment of the same date.5 Under the 1998 Stability Agreement SMCV would have not been subject to such fine.

In the Resolution dated 22 August 2018, the Tax Tribunal determined that:

  1. SMCV is not entitled to a waiver of penalties and interest because there is no “reasonable doubt” about the proper interpretation of the applicable legal provisions as required

Principal amounts to approximately US$6.48 million.

As of 31 December 2019, penalties and interest accumulated to around US$6.9 million.

On 22 August 2018, the Tax Tribunal confirmed SUNAT’s Assessment and Fine Resolutions.7

[Page 52]

Government's Violations of the Stability Agreement Amount (USD) Procedural Status
under Article 170 of the Tax Code.6 But SMCV is clearly entitled to such waiver because there was a “reasonable doubt” about the proper interpretation of the applicable legal provisions, as explained in paras. 12 and 127-133 of the Notice for Arbitration.
Income Tax 2007

In the Assessment dated 28 March 2012, SUNAT determined that:

  1. SMCV should have made certain payments to former Flotation Plant workers before filing its tax return on such payments to make them tax deductible.8 Under the 1998 Stability Agreement this requirement did not apply.
  2. SMCV should have depreciated the buildings of the Flotation Plant at a 3% rate.9 Under the 1998 Stability Agreement a 20% rate applied.
  3. SMCV failed to comply with formal requirements to deduct expenses of the Flotation Plant from previous fiscal years.10 Under the 1998 Stability Agreement these requirements did not apply.

In the Fine Resolution dated 28 March 2012, SUNAT determined that:

  1. SMCV had to pay a fine because it failed to report income in its tax return based on SUNAT’s findings in the Assessment of the same date.11 Under the 1998 Stability Agreement SMCV would have not been subject to such fine.

In the Fine Resolutions dated 28 March 2012, SUNAT determined that:

  1. SMCV should have kept the Flotation Plant accounting in Peruvian soles.12 Under the 1998 Stability Agreement SMCV was authorized to keep its accounting in US dollars.
  2. SMCV should have kept separate accounting for the Flotation Plant and Leaching Facility.13 Under the 1998 Stability Agreement SMCV was not required to have separate accounting for each investment because both are part of SMCV’s only Beneficiation Concession.

Principal amounts to approximately US$2.4 million.

As of 31 December 2019, penalties and interest accumulated to around US$776,242.

On 22 August 2018, the Tax Tribunal confirmed SUNAT’s Assessment and Fine Resolutions.15

Government's Violations of the Stability Agreement Amount (USD) Procedural Status

Annex B

TAX ASSESSMENTS RELATING TO THE STABILITY AGREEMENT THAT SMCV CHALLENGED BEFORE SUNAT

Government's Violations of the Stability Agreement Amount (USD) Procedural Status
Income Tax 2012

In the Assessments dated 26 November 2019, SUNAT determined that:

  1. SMCV should have not deducted the Special Mining Tax paid for the Flotation Plant.1 Under the 1998 Stability Agreement SMCV had the right to deduct the Special Mining Tax paid for both the Flotation Plant and the Leaching Facility.
  2. SMCV should have not deducted as an expense the payments made to suppliers from the Flotation Plant considered as “Missing Taxpayer.”2 Under the 1998 Stability Agreement such deductions were valid.
  3. SMCV should have provided proof of payment made to former Flotation Plant workers in order to make it tax deductible.3 Under the 1998 Stability Agreement this requirement did not apply.
  4. SMCV should have made certain payments to former Flotation Plant workers before filing its tax return on such payments to make them tax deductible.4 Under the 1998 Stability Agreement this requirement did not apply.
  5. SMCV should have depreciated the buildings of the Flotation Plant at a 5% rate.5 Under the 1998 Stability Agreement a 20% rate applied.
  6. SMCV should not have deducted the depreciation of fixed assets of the Flotation Plant.6 Under the 1998 Stability Agreement SMCV had the right to deduct the depreciation of fixed assets of the Flotation Plant and Leaching Facility.
  7. SMCV should not have depreciated fixed assets of the Flotation Plant which book value had been fully depreciated in previous years.7 Under the 1998 Stability Agreement SMCV had the right to such depreciations.

As of 31 December 2019, penalties and interest accumulated to around US$5.5 million.

On 26 December 2019 SMCV filed a reconsideration request to SUNAT. As an abundance of caution, on 27 February 2020, SMCV withdrew these stability-related claims for purposes of complying with Article 10.18.2(b) of the TPA.13

[Page 74]

Government's Violations of the Stability Agreement Amount (USD) Procedural Status
  1. SMCV failed to comply with formal requirements to deduct the depreciation of the HPGR of the Flotation Plant.8 Under the 1998 Stability Agreement these requirements did not apply.

In the Fine Resolution dated 26 November 2019, SUNAT determined that:

  1. SMCV failed to report income in its tax return based on SUNAT’s findings in the Assessment of the same date.9 Under the 1998 Stability Agreement SMCV would have not been subject to such fine.

In the Fine Resolution dated 26 November 2019, SUNAT determined that:

  1. The interest rate for tax liabilities in Peruvian soles applied.10 Under the 1998 Stability Agreement the interest rate for US dollars applied.

In the Fine Resolutions dated 26 November 2019, SUNAT determined that:

  1. SMCV should have kept the Flotation Plant accounting in Peruvian soles.11 Under the 1998 Stability Agreement SMCV was authorized to keep its accounting in US dollars.
  2. SMCV should have kept separate accounting for the Flotation Plant and the Leaching Facility.12 Under the 1998 Stability Agreement SMCV was not required to have separate accounting for each investment because both are part of SMCV’s only Beneficiation Concession.

[Page 75]

Government's Violations of the Stability Agreement Amount (USD) Procedural Status
Additional Income Tax 2012

In the Assessment dated 26 November 2019, SUNAT determined that:

  1. SMCV is subject to an additional income tax of 4.1% on non-deductible expenses (deemed dividends) from the Flotation Plant.14 Under the 1998 Stability Agreement this additional tax did not apply.

Principal amounts to approximately US$929,487.

As of 31 December 2019, penalties and interest accumulated to around US$944,359.

On 26 December 2019, SMCV filed a reconsideration request to SUNAT. As an abundance of caution, on 27 February 2020, SMCV withdrew these stability-related claims for purposes of complying with Article 10.18.2(b) of the TPA.15
Temporary Tax on Net Assets 2012
On 21 December 2017, SMCV submitted and paid its tax return on Temporary Taxes on Net Assets for the Flotation Plant with reservation of rights to avoid incurring penalties and interest.16 Under the 1998 Stability Agreement SMCV was exempt from the Temporary Tax on Net Assets.

Principal amounts to approximately US$7.5 million.

As of 31 December 2019, penalties and interest accumulated to around US$3.1 million.

SUNAT accepted SMCV’s tax return and payment.
Temporary Tax on Net Assets 2013

In the Assessment dated 20 November 2019, SUNAT determined that:

  1. SMCV should have paid the Temporary Tax on Net Assets for the Flotation Plant.17 Under the 1998 Stability Agreement SMCV was exempt from the Temporary Tax on Net Assets.

Principal amounts to approximately US$10.8 million,

As of 31 December 2019, penalties and interest accumulated to around US$10.5 million.

On 18 December 2019, SMCV filed a reconsideration request to SUNAT. As an abundance of caution, on 27 February 2020, SMCV withdrew these stability-related claims for purposes of complying with Article 10.18.2(b) of the TPA.18
Special Mining Tax 2013

In the Assessment dated 28 September 2018, SUNAT determined that:

  1. SMCV should have paid the Special Mining Tax for the Flotation Plant.19 Under the 1998 Stability Agreement SMCV was exempt from the Special Mining Tax.

Principal amounts to approximately US$23.5 million.

On 28 May 2019, SUNAT confirmed its prior Assessment and Resolution.22

  1. SMCV is not entitled to a waiver of penalties and interest because there is no “reasonable doubt” about the proper interpretation of the applicable legal provisions as required under Article 170 of the Tax Code.21 But SMCV is clearly entitled to such waiver because there was a “reasonable doubt” about the proper interpretation of the applicable legal provisions, as explained in paras. 12 and 127-133 of the Notice for Arbitration.
Complementary Mining Pension Fund Tax 2013

In the Assessment dated 20 December 2019, SUNAT determined that:

  1. SMCV should have paid the Complementary Mining Pension Fund Tax for the Flotation Plant. SUNAT determined SMCV’s tax liability based on the entirety of its net income because SUNAT was unable to determine SMCV’s tax liability based only on its Flotation Plant-related income.23 Under the 1998 Stability Agreement SMCV was exempt from the Complementary Mining Pension Fund Tax.

Principal amounts to approximately US$3.8 million.

As of 31 December 2019, penalties and interest accumulated to around US$3.2 million.

On 22 January 2020, SMCV filed a reconsideration request to SUNAT. As an abundance of caution, on 27 February 2020, SMCV withdrew these stability-related claims for purposes of complying with Article 10.18.2(b) of the TPA.24
