Resolution of International Transfer-Pricing Disputes
Resolution of International Transfer-Pricing Disputes Yitzhak Hadari* PRÉCIS La question de l’heure en fiscalité internationale vise les différends entre les autorités fiscales et les multinationales en matière de prix de transfert. Leur résolution exige la mise en équilibre des intérêts respectifs des deux parties. D’une part, les autorités fiscales tentent d’assujettir le revenu mondial des multinationales à un niveau d’imposition approprié et d’atteindre une répartition appropriée de ce revenu entre les administrations visées. D’autre part, les multinationales souhaitent mener leurs activités et préserver leur rôle de principal moteur de l’économie mondiale, sans être assujetties à une double imposition. Elles s’attendent à pouvoir fonctionner dans le cadre d’une structure fiscale mondiale leur offrant un degré raisonnable de certitude, alliée à des résultats uniformes et équitables. Les principaux régimes fiscaux du monde, qui s’appliquent aux multinationales, ont en général adopté le principe de la pleine concurrence comme principale norme en matière de prix de transfert. Toutefois, il existe des différences marquées entre les administrations quant aux méthodes précises devant servir à déterminer les prix de transfert acceptables pour les opérations au sein de multinationales. Dans cet article, l’auteur suggère de ne plus mettre l’accent sur les méthodes appropriées, mais plutôt sur les mécanismes appropriés pour régler les différends entre les contribuables et les administrations fiscales intérieures, et entre les administrations fiscales nationales et les multinationales à l’échelle internationale. L’auteur traite de plusieurs mécanismes qui ont évolué sur ces deux plans, notamment les ententes anticipées en matière de prix de transfert (EAPT), la procédure d’examen simultané (PES), les règles d’exonération et l’arbitrage. De l’avis de l’auteur, ces mécanismes de résolution des différends sur la scène internationale devraient être intégrés aux conventions fiscales, en vertu de l’article 25 du traité type de l’OCDE. Il propose que les procédures de consentement mutuel comprennent au moins l’une des techniques suivantes, selon les préférences des parties au traité.

Quatrièmement, tous les traités devraient comprendre le recours à l’arbitrage obligatoire et exécutoire, sous réserve du consentement du contribuable, pour supprimer la double imposition lorsque les autorités compétentes n’arrivent pas à s’entendre relativement à un cas donné. Ce recours ne devrait être utilisé qu’après un délai déterminé à partir du moment de la soumission du cas aux autorités compétentes.

Les autres mécanismes mentionnés pourraient être recommandés ou mentionnés dans le commentaire sur le modèle de l’OCDE. Comme mesure provisoire, pour faciliter l’acceptation de la procédure arbitrale, l’OCDE pourrait recommander expressément l’adoption du mécanisme d’arbitrage dans le cadre de son étude actuelle sur les prix de transfert. ABSTRACT Transfer-pricing disputes between tax authorities and multinational enterprises (MNEs) are the most important issue in international taxation today. Their resolution requires a balancing of the respective interests of both parties. On the one hand, tax authorities seek to subject MNEs to an appropriate level of taxation on their global income and to achieve an appropriate allocation of that income among the jurisdictions involved. On the other hand, MNEs wish to conduct their activities and preserve their role as the major driving force in the world economy without being subjected to double taxation. They expect to be able to operate within a world tax structure that offers them a reasonable degree of certainty coupled with uniform and equitable results. The world’s major tax systems, which apply to MNEs, have generally united under the umbrella of the arm’s-length principle as the main substantive standard applicable to transfer pricing. However, important differences exist between jurisdictions regarding the specific methods that should be used to determine acceptable transfer prices for transactions within MNE groups. In this article, the author suggests that the focus should be shifted from the appropriate substantive methods to the appropriate mechanisms for resolving conflicts between taxpayers and domestic tax administrations at the national level, and between national tax (1998), Vol. 46, No. 1 / no 1 RESOLUTION OF INTERNATIONAL TRANSFER-PRICING DISPUTES 31 administrations and MNEs at the international level. The author discusses several mechanisms that have evolved at both levels—specifically, advance pricing agreements (APAs), the simultaneous examination procedure (SEP), safe harbours, and arbitration. In the author’s view, these mechanisms for dispute resolution in the international arena should be incorporated into binational tax treaties, pursuant to the mutual agreement procedure of article 25 of the OECD model treaty. The author proposes that the mutual agreement procedure should include one or more of the following techniques, according to the preferences of the treaty parties. At the first level, the competent authorities and domestic tax administrations would encourage taxpayers to conclude APAs in order to resolve transfer-pricing issues in advance and on a case-by-case basis. At the second level, the SEP should be specifically included in treaties in order to facilitate information sharing between collaborating tax authorities, and specifically the exchange of audit information pertaining to MNEs. At the third level, agreement on some limited safe harbours within the arm’s-length norm is desirable. At the fourth level, all treaties should include recourse to compulsory and binding arbitration, subject to the taxpayer’s consent, to eliminate double taxation when the competent authorities cannot reach agreement in a given case. Such recourse should be used after a defined period from the time the case was referred to the competent authorities. It is further proposed that the OECD model for binational tax treaties should be amended to include a compulsory and binding arbitration mechanism. The other noted mechanisms could be recommended or mentioned in the commentary on the OECD model. As an interim step, to assist acceptance of the arbitration procedure, the OECD could specifically recommend adoption of this mechanism in its ongoing study of transfer pricing. OBJECTIVES AND NEEDS The phenomenon of the multinational enterprise (MNE) is by no means new to international lawyers and tax specialists. Pioneering studies of MNEs by legal scholars began to appear some 25 years ago. My own work in this area at that time focused on the structure and control of MNEs, particularly those enterprises with closely integrated operations.1 In a subsequent study, I recommended that this aspect of control should be taken into account by national policy makers, legislatures, and courts in the policy, law-making, and interpretation processes.2 The courts also have 1 Yitzhak Hadari, “The Structure of the Private Multinational Enterprise” (March 1973), 71 Michigan Law Review 729-806. 2 Yitzhak Hadari, “The Choice of National Law Applicable to the Multinational Enterprise and the Nationality of Such Enterprises” [1974], no. 1 Duke Law Journal 1-57. (1998), Vol. 46, No. 1 / no 1 32 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE addressed the MNE phenomenon in applying domestic laws3 to the MNE or its associated enterprises, which are part of the global MNE group. 4 The main issues in the international tax area have been, in my view, • how the global income of MNE groups should be allocated; • what is the proper standard (norm) to be applied; and • how this allocation process can be coordinated within the frameworks of national policies and domestic laws of the various participating countries to the satisfaction of all concerned. The overriding concern is how to protect national revenues and at the same time accommodate the needs of MNEs themselves, so that they can continue to operate at optimal capability without being subjected to double, or even multiple, taxation on their global income. It follows that, in order to meet these objectives, there is a need for a worldwide consensus as to the proper yardstick or standard of allocation to be applied on the national level, and for an agreement among world tax authorities to resolve problems according to international tax law norms, while tendering simultaneous protection to the needs of national tax administrations and MNE groups. It is admitted at the outset that the issues in this area are among the most complex in the taxation field, primarily because of the wide range of subjects involved. Of particular difficulty is the issue of transfer pricing—how to determine a fair price, for tax purposes, for transactions between associated (or related) enterprises located in different tax jurisdictions. 5 Analysis of this issue and the development of appropriate solutions call for special economic, tax, and legal expertise. It is necessary, for example, to collect a large body of reliable data, which indeed may not be readily available; to bring to the analysis a deep understanding of the economic factors associated with intercompany transactions; and to possess a similar understanding of MNEs generally and of the particular industry under consideration. Added to these requirements is the need for detailed knowledge of the tax legislation of the various countries in which the particular MNE group operates. 3 For example, First Nat. City Bank v. Banco Para El Comercio, 462 US 611 (1983), wherein the US Supreme Court applied theory in the international banking area to the local entity of the MNE, citing, at 629, several legal studies of the MNE, including Hadari, supra footnote 1. 4 The latest nomenclature of the OECD (which generally conforms to the theories and terminology I used in the articles cited previously, supra footnotes 1 and 2) explains the differences between the legal entities and the economic entities of the MNE: Organisation for Economic Co-operation and Development, Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (Paris: OECD) (looseleaf ) (herein referred to as “the OECD report”). 5 The OECD report observes that “one of the most difficult issues that has arisen is the establishment for tax purposes of appropriate transfer prices. Transfer prices are the prices at which an enterprise transfers physical goods and intangible property or provides services to associated enterprises.” Ibid., preface, at paragraph 11. (1998), Vol. 46, No. 1 / no 1 RESOLUTION OF INTERNATIONAL TRANSFER-PRICING DISPUTES 33 The need for a better solution to transfer-pricing disputes between MNEs and national tax authorities is manifest. The significance of MNE intragroup transactions in the world economy today is suggested by the fact that 33 percent of the world trade of goods is within MNE groups, 6 and such trade has been growing at a relatively rapid pace in recent decades. 7 It is clear that substantial tax revenues are at stake in the absence of adequate transfer-pricing controls. The US Internal Revenue Service ( IRS) and the US courts have more experience in this area than their counterparts in any other country. US judges have attested that their files in a typical MNE case are of a magnitude unmatched in most other legal areas, including antitrust, and that MNE cases account for some of the biggest tax deficiencies. 8 It is acknowledged that, at least until recently, the US tax authorities have generally failed to cope adequately with MNEs, and particularly with foreign-based MNE groups, which are considered by US tax authorities to have drastically underpaid their fair share of US taxes owed. 9 Subsequent to the IRS’s efforts to collect its fair share of the taxes imposed on MNEs’ taxable income, there were reports of US litigation exceeding $32 billion in tax deficiencies in 1992.10 6 United States, General Accounting Office, “International Taxation: Problems Persist in Determining Tax Effects of Intercompany Prices” (1992). According to another study, intercompany transactions accounted for 43 percent of reported (book) worldwide income of US MNEs, originating from their foreign affiliates: “U.S. International Tax Policy for a Global Economy,” prepared for National Chamber Foundation by Price Waterhouse, April 15, 1991, reported in Jamie Elliott, “Developments in Transfer Pricing” [1995], no. 4 British Tax Review 348-57, at 348, footnote 5. 7 For earlier figures, see Hadari, supra footnote 1, at 739-40. 8 For example, one famous case resulted in a 196-page decision of the US Tax Court: Eli Lilly and Co. and Subsidiaries, 84 TC 996 (1985), aff ’d. in part, rev’d. in part and remanded, 856 F2d 855 (7th Cir. 1988). Another decision of the same court produced a 190-page opinion: Sunstrand Corporation, 96 TC 226 (1991). For the magnitude of the testimony and litigation, see Philip J. Bergquist and Kenneth A. Clark, “Arbitration of Transfer Pricing Disputes,” in Robert Feinschreiber, ed., Transfer Pricing Handbook (New York: Wiley, 1993), 549ff., at 551-52. As of May 1992, section 482 cases amounted to over 42 percent of the total number of cases of more than $10 million dollars, and the total amount of tax involved in section 482 cases exceeded $4 billion: See “Report of the Office of Special Counsel,” in Reports of the United States Judicial Conference (November 1992), exhibit 10. See also supra footnote 6 and infra footnote 9 and accompanying text. 9 See Francis M. Allegra, “Section 482: Mapping the Contours of the Abuse of Discretion Standard of Judicial Review” (Winter 1994), 13 Virginia Tax Review 423-515, at 426-27, citing statistics for several years ago. For example, in 1986, 45,000 US foreign affiliates reported $543 billion in sales and $1.5 billion in net losses. In 1987, such sales resulted in $687 billion of taxable income, but only $4.6 billion in income tax paid—that is, the effective rate of tax was 0.66 percent, about half the rate paid by US-controlled MNE groups. Later reports continue to support those statistics with respect to all MNE groups: see Report by the Controller General to the Congress, “International Taxation: Transfer Pricing and Information on Nonpayment of Tax,” GAO-GGD 95-101 (1995). See also supra footnote 8. 10 See articles and notes cited by Allegra, supra footnote 9, at 432, and a list of the then pending cases at the Tax Court involving many of the gigantic MNEs with headquarters all (The footnote is continued on the next page.) (1998), Vol. 46, No. 1 / no 1 34 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE THE INTERNATIONAL NORM There are two basic approaches for resolving such questions as proper transfer pricing or division of MNE group income among the participating tax jurisdictions. One is the direct or formulary apportionment approach, which attempts to define and determine the global income of the MNE group and then adopts the proper formula based on economic parameters for the just division of its income among the participating jurisdictions.11 This approach ignores the distinct economic or legal entities that constitute the MNE group, instead treating the group as one economic entity. The second approach is the indirect or transactional approach. Under this approach, each national MNE is recognized as an independent economic entity, but not necessarily a distinct legal entity, which is a part of the global MNE group. The MNE could therefore be an independent and distinct legal entity under domestic law (for example, a corporate body such as a corporation under US corporation law or a company under UK company law), or it could be a local branch of a foreign corporation, which, for tax purposes, is regarded as a separate entity. A local branch of a foreign corporation with substantial domestic activities is usually considered a permanent establishment (PE) under the bilateral tax treaties and is taxed locally as if it were an independent legal entity. Under the transactional approach, a price must be attached to every transaction between MNEs located in different tax jurisdictions. Therefore, each transaction within the MNE group across national borders is usually subject to domestic taxation. From a theoretical point of view, there is a very strong preference for the direct formulary apportionment approach. No one could forcefully argue against an internationally agreed upon formula, including all its components and measurements, along the lines of the US unitary state systems regarding states’ franchise tax. 12 Of course, the optimal solution would be an international organization such as the International Court of 10 Continued . . . over the globe—for example, Exxon, Texaco, Mobil, Apple Computer, Nestle, Chevron, Hitachi, Converse, Yamaha Motor, and National Semiconductor. 11 For discussion of the formulary apportionment approach in the MNE context, see generally, and the references there cited, Reuven S. Avi-Yonah, “The Rise and Fall of Arm’s Length: A Study in the Evolution of U.S. International Taxation” (Summer 1995), 14 Virginia Tax Review 89-159, at 92; and Monica Brown Gianni, “Transfer Pricing and Formulary Apportionment” (March 1996), 74 Taxes: The Tax Magazine 169-82, at 170. See also Asim Bhansali, “Note: Globalizing Consolidated Taxation of United States Multinationals” (May 1996), 74 Texas Law Review 1401-38, in which the author argues for a US unilateral repeal of the arm’s-length norm, ending the tax deferral of US-based MNEs, and the adoption of consolidated income tax returns for MNE groups with an apportionment formula for determining source of income for purposes of the US foreign tax credit, and thus avoiding double taxation. 12 Barclays Bank v. Franchise Tax Bd. of California, 114 S. Ct. 2268 (1994); Exxon Corp. v. Wisconsin Dept. of Revenue, 447 US 207 (1980); and Mobil Oil Corp. v. Commissioner of Taxes, 445 US 425 (1980). Compare F.W.

Although such proposals have been suggested repeatedly during a great part of the 20th century, no progress has yet been reported. Not only was the formulary apportionment approach rejected by the OECD; but even the regional markets, including the former European Communities or the European Union with their supranational laws and institutions, have not achieved such an objective. As a result, the international transfer-pricing norm has developed along the lines of the indirect, transactional method. Major progress in the area of international taxation has been made by the OECD and its predecessor, the OEEC.14 Both organizations promoted the concept of bilateral tax treaties, negotiated between two countries, for the purpose of avoiding international double taxation and preventing international tax avoidance. Many countries now have in place tax treaties that generally follow the OECD model. With respect to the taxation of MNE s, the OECD has subscribed to the transactional separate-entity approach, respecting the independence of each MNE whether it is incorporated as an independent legal entity or not. This position is reflected in article 9 of the OECD model, which sets out the arm’s-length standard, and in article 7, which addresses the taxation of PEs such as branches, although the latter article also permits the use of a formulary apportionment approach in certain circumstances. Under article 7, if an MNE did not establish itself in a host country as a separate legal entity and operated as a PE under the OECD model, it would deal with its foreign-based headquarters, pursuant to article 7(2), as though two independent entities were involved. The PE would then be entitled, under article 7(3), to deduct its business expenses as though it were a separate legal entity. The OECD model recognizes that many countries treat the foreign branch and its headquarters as a single entity, which they legally are. Accordingly, article 7(4) provides that the income of the PE may be attributed on the basis of a formulary apportionment method where it is customary for the two countries involved to apply such a method. This exception is not allowed when the entities are related, under article 9, which is the general article that applies to most intercorporate transactions of MNE groups. Even in the exception for PE s, the OECD model emphasizes that final 13 OECD report, supra footnote 4, at paragraph 4.168. The Organisation for European Economic Co-operation (OEEC) made its first recommendation concerning double taxation on February 25, 1955, on the basis of the work commenced in 1921 by the League of Nations, with the first model treaty in 1928. This is the historical origin of the model tax treaty developed by the OECD, initially published in 1963 and now in its 1992 version with current updates: Organisation for Economic Cooperation and Development, Model Tax Convention on Income and on Capital (Paris: OECD) (looseleaf ) (herein referred to as “the OECD model”), I-1 et seq. 14 (1998), Vol. 46, No. 1 / no 1 36 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE results must conform to the separate-entity test and provides that “the results shall be in accordance with the principles contained in the Article.” What are the standards or criteria to be applied under the separateentity approach? It has been well established by international agreements that it is the so-called arm’s-length standard that should apply; namely, each transaction between the associated enterprises of the MNE or the MNE group should be priced as it would be if it were carried out by unrelated entities. The arm’s-length standard was adopted in the first major study of transfer prices and MNE s by the OECD in 197915 and is acknowledged by paragraph 3 of the OECD commentary on article 9(1) of the OECD model. Article 9(1) prescribes: Where a) an enterprise of a Contracting State participates directly or indirectly in the management, control or capital of an enterprise of the other Contracting State, or b) the same persons participate directly or indirectly in the management, control or capital of an enterprise of a Contracting State and an enterprise of the other Contracting State, and in either case conditions are made or imposed between the two enterprises in their commercial or financial relations which differ from those which would be made between independent enterprises, then any profits which would, but for those conditions, have not so accrued, may be included in the profits of that enterprise and taxed accordingly. The arm’s-length standard has also been endorsed by the UN model treaty between developed and developing countries.16 The United States has varied its position on the arm’s-length standard. Initially, it endorsed the standard and incorporated it into domestic tax legislation—specifically, section 482 of the Internal Revenue Code and the detailed 1968 regulations promulgated under that section.17 The United States also tried to apply the arm’s-length standard through attempts to obtain or establish data for comparable unrelated transactions. In addition, the United States convinced most of its trading partners to adopt similar specific arm’s-length rules and generally to adhere to the main 15 Organisation for Economic Co-operation and Development, Transfer Pricing and Multinational Enterprises (Paris: OECD, 1979). 16 United Nations, Model Double Taxation Convention Between Developed and Developing Countries, UN publication ST/ESA/102 (New York: UN, 1980). 17 Internal Revenue Code of 1954, as amended.

Germany was one of the first countries to follow, 18 then Canada,19 Australia, 20 France, 21 and others.22 The United Kingdom has traditionally preferred to resolve its transferpricing disputes by settlement. 23 This approach, set out in an Inland Revenue memorandum (made public in a 1981 press release), is based on the arm’s-length standard and has been upheld by the courts. 24 Although the United Kingdom has enacted general statutory provisions that address the taxation of MNEs, the absence of detailed rules leaves ample room for flexible solutions. This flexibility has been preferred by the UK Inland Revenue.25 Recently, however, the United Kingdom released draft legislation, in a consultative document, announcing a new transfer-pricing 18 In addition to the statutory provisions of 1972, the German tax authorities published a handbook of detailed guidelines in 1973, similar to the US 1968 regulations. For a brief survey, see Alan Stroad and Colin Masters, Transfer Pricing (London: Butterworths, 1991), 113-15. 19 Canada generally followed the US example, with variations, and the OECD recommendations. In September 1997, draft transfer-pricing legislation was tabled, adopting the arm’s-length standard on the basis of comparable independent transactions, while also permitting the use of a profit-based method in certain circumstances, and requiring taxpayers to maintain contemporaneous transfer-pricing documentation and records. See Allan Lanthier and Diane Bale, “Transfer-Pricing Proposals” (October 21, 1997), 5 Canadian Tax Highlights 73; and Nathan Boidman, “Canada To Revamp Regime To Set Things Right” [December 1997], International Tax Report 1-5. For a brief description of the existing law, see Stroad and Masters, supra footnote 18, at 120-26. 20 Australia entered into an advance pricing agreement with the United States in 1990, and even extended it to a bilateral agreement based generally on the arm’s-length norm and the OECD guidelines: see infra footnotes 89-92 and accompanying text. 21 France has adopted a more flexible approach. For a brief survey, see Stroad and Masters, supra footnote 18, at 115-19. 22 For example, see New Zealand’s recent revised guidelines in (November 17, 1997), vol. 31, no. 46 Tax News Service 456. There are several tax services on the transfer-pricing laws of most countries and even a recent periodical entitled International Transfer Pricing.

The first move was to add section 367(d) to the Internal Revenue Code. Section 367(d) was intended to deal with a specific abuse of the transferpricing regime whereby US MNEs developed local patents and other intangible property, transferred them in tax-free transactions to no-tax or low-tax jurisdictions such as Puerto Rico, where those assets were exploited, and sold their production back to the US MNE or to other members of the MNE group, for worldwide distribution. This “round trip” resulted in major US tax losses, which the IRS attempted to recover—as noted above, with variable success—through the courts.32 Generally, under section 367(d), a transfer of intangibles to a foreign entity subjects the US person to tax on additional ordinary income during the useful life of the transferred intangible in an amount “commensurate” with the income from the intangible, instead of the possible tax-free 26 Chris Adams, “Practical Effects of UK Draft Legislation,” [November 1997], International Tax Report 1-4. 27 For the development of the Japanese rules, practice, and policy, especially vis-à-vis the United States, see Joseph H.

The regulations under section 367(d) generally apply the section 482 regulatory standards for determining the amount of attributed income.33 The second reform undertaken by the US tax administration was the introduction of revised regulations under section 482. The 1992 proposed regulations were based on a 1988 US Treasury white paper,34 but they adopted an approach different from that of the white paper on several issues. Specifically, they introduced new standards for the taxation of MNEs, which involved new profit-based transfer-pricing concepts that departed from the arm’s-length standard.35 The proposed regulations created uncertainty and the potential for double taxation of MNE s.36 For example, the proposals allowed the IRS to infer an ambiguous “prudent business standard” in lieu of a comparable based on uncontrolled enterprises. These US transfer-pricing initiatives caused concern in the international tax community, leading to the major OECD study on transfer pricing and the issuance of detailed guidelines, published in draft form in 199437 and formally adopted in 1995.38 The OECD study, although based on the international arm’s-length standard, was strongly influenced by the US reform initiatives. 33 See John P.

(1998), Vol. 46, No. 1 / no 1 40 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE The OECD report followed the new US temporary regulations of 199339 and the final regulations of 1994, 40 which changed or relaxed some of the controversial new standards while preserving some of the new methods, adding flexibility and attempting to evaluate the transfer prices on comparables in keeping with international tax norms. Yet another international agreement strongly supports the arm’s-length norm: the European Community arbitration convention 41 has adopted the arbitration mechanism as a solution for transfer-pricing double taxation conflicts within the European Union. The EC convention procedure is grounded entirely on the arm’s-length standard as stated in the OECD model.42 Thus, out of various studies and regulations on both sides of the Atlantic, there have emerged—albeit with some differences—generally uniform norms for determining the transfer prices of MNE s, basically along the lines of the arm’s-length standard, and in general conformity with the OECD model and most existing bilateral tax treaties. I am not suggesting that the new international tax regime fully meets the objectives set forth earlier.43 However, the revised standards, elaborated below, together with new dispute-resolution mechanisms introduced by the United States and the European Union open the door to the adoption of changes in bilateral tax treaties, which would achieve further improvement of the world’s tax systems for mitigating conflicts with MNEs. Before I outline these proposed changes, it is important to summarize the revised transfer-pricing standards contained in the OECD report and the US final regulations. THE REVISED STANDARDS FOR SETTING TRANSFER PRICES The US deviation from the accepted arm’s-length standard originated in the Tax Reform Act of 1986, when Congress, worried by the evidence that MNE s were underpaying US taxes, mandated that the Treasury should 39 See generally Peter A.

Since uncontrolled comparables are often difficult, if not impossible, to find, the 1968 US regulations provided for a “fourth method”—a method of last resort—which might be used in lieu of the first three approved methods where no comparables are available for determining a fair transfer price.46 Two of the innovations of the 1994 US regulations are 1) their greater flexibility, resulting from the repeal of the priority of the above long-established methods and the recognized superiority of the “comparable uncontrolled price method”; and 2) the recognition of the “best method rule,” which requires the taxpayer to select the method that produces the “most accurate determination” of the arm’s-length price. 47 In fact, some old US cases adopted the noted “fourth method”—a profitbased approach to transfer pricing—emphasizing the profitability of the MNE’s associates 48 on the basis of a return of gross income to total operating costs of functionally similar enterprises, or profit split among the enterprises, and using round figures without specific economic analysis.49 Both the 1988 white paper and the OECD report highlighted profit-based methods, although the white paper said that the “fourth method” as developed by the courts has been inadequate.50 For example, the white paper described the “profit split method,”51 which now appears in the regulations,52 as first analyzing the functions performed by each associated enterprise with the proper allocation of market rate of return to each function on the basis of comparables.

One commentator has specifically suggested that the profit-split method is based on a flexible formulary apportionment approach.54 In part, however, it refers to the arm’s-length standard in that the split of profit is based upon “an economically valid basis that approximates the division of profits that would have been anticipated and reflected in an agreement made at arm’s length.”55 The comparable profits method is expected to play a major role in US transfer-pricing cases.56 It is expected that disputes between MNEs and the taxing authorities will continue with resulting litigation. Cases involving very profitable intangibles might call for use of the profit-split method under the “best method rule” owing to a lack of comparables.57 One may refer to this method as “[l]imited formulary apportionment.”58 We have to wait for audits of current tax years based on the new US regulations. However, US statistics have been continuing to show underpayment of taxes by MNEs, 59 giving support to the demand for application of the global formulary apportionment approach,60 with its inevitable adverse effect of international double taxation. Double taxation for highly integrated MNEs is very likely to occur even now under the current US regulations. 53 Treas. reg. section 1.482-6(c). Avi-Yonah, supra footnote 11, at 94 and 129 et seq.

Although a similar concept, the transactional net margin method, was substituted, the OECD report tried to limit its application in conformity with the arm’s-length norm. That position is consistent with the report’s unequivocal rejection of the global formulary apportionment approach.63 The OECD report expressly states that in the majority of cases, the traditional transactional methods should apply, and profit-split methods would apply only in cases of last resort when traditional methods were unsatisfactory. The OECD report is much more reserved than the 1994 draft, stressing that “even in a case of last resort, it would be inappropriate to automatically apply a transactional profit method without first considering the reliability of that method.”64 The OECD report and the US regulations have narrowed the gap that previously existed between the OECD and US approaches, 65 but there is still a risk that final results under the new US system will be incompatible with the internationally accepted arm’s-length standard. The US Treasury admitted that [t]o the extent that they [profit-split methods] do not rely on such results [of unrelated parties] they may be considered to be inconsistent with the arm’s length standard. There are, however cases in which it is impossible to locate adequate data to reliably apply one of the methods. In such a case a profit split may be the best available method.66 The OECD’s acceptance of profit-split transfer-pricing methods is, as noted above, somewhat qualified. The OECD report observed: 61 Treas. reg. section 1.482-5. 1994 OECD draft report, supra footnote 37, at 20.

Wright, “In the OECD and the United States It’s the Arm’s Length Principle That Matters: Comparison of New Transfer Pricing Regulations” (January 1995), 2 International Transfer Pricing Journal 28-44. 66 “Treasury Press Release on Final Section 482 Regulations,” Tax Notes Today, July 6, 1994. 62 (1998), Vol. 46, No. 1 / no 1 44 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE [T]here are substantial concerns regarding the use of the transactional net margin method, in particular that it may be applied without adequately taking into account the relevant differences between the associated enterprises and the independent enterprises being compared. Many countries are concerned that the safeguards established for the traditional transactional methods may be overlooked in applying the transactional net margin method. Thus, where differences in the characteristics of the enterprises being compared have a material effect on the net margins being used, it would not be appropriate to apply the transactional net margin method without making adjustments for such differences.67 The OECD report therefore stresses that the comparability standard must be applied to the transactional profit methods and that considerable caution must be used in attempts to apply such methods. Profit methods should not be applied if they cannot produce an arm’s-length result,68 and “as a general matter the use of transactional profit methods is discouraged.”69 Nevertheless, the OECD report accepted the approach adopted in the US regulations, 70 conceding that when the traditional transactional methods could not supply satisfactory results, they could be supplemented with transactional profit methods as a last resort.71 Such difficult cases occur in MNE groups with intercompany transactions in highly integrated production of highly specialized advanced products, particularly in high technology or communications, and are typically associated with unique and very valuable intangibles. Such transactions have characterized MNEs, and have been dominated by MNEs, for a long time.72 It has already been noted that the OECD flatly rejected any non-arm’slength approach such as global formulary apportionment (probably based on some combination of costs, assets, payroll, and sales, or a rate of return ratio of each MNE relative to the MNE group). A formulary approach within the boundaries of the transactional profit method applied on a case-by-case basis to one or more associated enterprises, and compared with comparable independent enterprises, is therefore theoretically an internationally accepted variation within the arm’s-length norm. 73 But there is a great risk that the borderline between the two methods is too fine and might be nullified by domestic tax administrations, with the unavoidable result of double taxation. 67 Supra footnote 4, at paragraph 3.53.

Even APAs are usually bilateral. Perhaps if they were to be extended on a multilateral basis—and there are signs in this direction 74—global formulary apportionment might be reconsidered. Acceptance of global formulary apportionment will likely gain momentum only if and when the majority of countries reach the conclusion that the current international tax regime applicable to MNE groups is not functioning adequately, and they are ready to replace it with another system. That is not yet the case, and in my opinion, all efforts must be directed at improving the current regime in accordance with the conclusions of the OECD report. 75 ALTERNATIVE MECHANISMS FOR RESOLVING INTERNATIONAL PRICING DISPUTES As has been observed, despite the convergence of accepted transfer-pricing methods among tax administrations, important differences continue to exist, and the potential for major disputes with MNEs remains.76 Current progress in the development of international mechanisms for dispute resolution could help in alleviating conflict and hardship. Advance Pricing Agreement In 1991, the IRS introduced the APA procedure. The idea has been welcomed by legal scholars all over the world.77 Pursuant to this program, the MNE sets out in detail the transfer-pricing methods it proposes to use and negotiates acceptance of those methods, or substitution of another approach, with the tax administration before the transactions in question commence.78 If the parties reach agreement, the MNE gains certainty regarding the domestic tax results, and both parties can avoid an extremely expensive transfer-pricing dispute. In the international arena, such agreement will contribute significantly to the avoidance 74 See the discussion of APAs below under the heading “Alternative Mechanisms for Resolving International Pricing Disputes.” 75 Supra footnote 4, at paragraphs 3.58 to 3.74. 76 See supra footnotes 6 to 10 and accompanying text. 77 See, for example, the articles by Fallon, infra footnote 78; Avi-Yonah, supra footnote 11, at 154; and Guttentag and Miyatake, supra footnote 27, at 187 et seq. 78 Rev. proc. 96-53, 1996-2 CB 375, which updates and supersedes Rev. proc. 91-22, 1991-1 CB 526.

Thus, the APA can serve as a flexible solution for transfer-pricing conflicts and should be further improved and developed.79 At present, the APA procedure is very complex and expensive, requiring extensive discovery and documentation that is almost as comprehensive as that required in section 482 litigation.80 Nevertheless, it is an excellent vehicle, which should be simplified and thus opened to medium-sized and small MNE s, in order to ensure equality and equity. 81 In addition, consideration should be given to the publication of APA s—of course, respecting taxpayer confidentiality—in order to provide guidance to other taxpayers. Obviously, if an APA is administered unilaterally, it will suffer from the single-country process. Therefore, a binational process is much preferred, assuming that a wide multilateral process is not a feasible alternative. In regional markets, it could be further expanded. An APA is not a “last resort” substitute for traditional administrative, judicial, and treaty mechanisms for resolving transfer-pricing disputes; rather, it supplements them. As discussed below, 82 in order to avoid double taxation, it is recommended that treaty partners be informed of unilateral APA s, so that a bilateral or multilateral solution may be considered under the mutual agreement procedure.83 Formally, the taxpayer would invoke the other country’s competent authority under the treaty. 84 In this way, an accord between tax administrations could be achieved, and the drawback of an unacceptable unilateral APA based on a unique economic factor or method would be avoided.85 79 OECD report, supra footnote 4, at paragraph 4.151.

(1998), Vol. 46, No. 1 / no 1 RESOLUTION OF INTERNATIONAL TRANSFER-PRICING DISPUTES 47 In a 1996 release, the IRS further developed the APA program, and specifically the bilateral APA , under which the IRS will commence competent authority treaty negotiations before the conclusion of the APA with the US taxpayer.86 Thus, the other treaty partner will be a full party to the process. It should be noted that an APA differs from domestic advance ruling procedures in that it involves an extensive factual process. An APA may also cover a series of transactions over an extended period, as well as current, past, or prospective tax years.87 An APA involves all the associated enterprises of the MNE group and therefore requires the invocation of the mutual agreement procedure under relevant tax treaties with other countries. The US APA program has added guidelines for functionally fully integrated MNE groups. 88 The APA has been gaining the support of countries in addition to the United States, including Canada,89 Japan, 90 Australia, Germany, the Netherlands, and, to a lesser extent, France, Italy, and the United Kingdom.91 This widespread adoption of APAs is in turn building support for bilateral advance pricing agreements (BAPAs).92 Under a BAPA , an MNE would supply information simultaneously to the national tax authorities (competent authorities) involved; the competent authorities would agree on the methods and practical auditing procedures to be applied, based on the OECD guidelines; and the competent authorities would coordinate attempts to reach agreement, deferring the conclusion of any unilateral APA with the MNE. The MNE would not participate in the process but would be notified of the results by its competent authority. If consent were reached, the MNE would enter into a parallel domestic 86 Rev. proc. 96-53, supra footnote 78. See Henry J. Birnkrant and Robert T.

Pursuant to the SEP, each national tax authority conducts the auditing of the MNE independently and separately in its own jurisdiction, and the audit findings are exchanged between the countries involved. The SEP is not a substitute for the mutual agreement procedure. Rather, “[a]ny exchange of information as a result of the [SEP] continues to be exchanged via the competent authorities, with all the safeguards that are built into such exchanges.”95 Competent authorities of various countries often conclude working arrangements that set out the objectives and procedures for simultaneous auditing and the exchange of information.96 The legal basis for the SEP is the exchange-of-information provision, article 26 of the OECD model adopted in individual binational treaties. Article 26 and the commentary allow exchanges of information upon request, spontaneous exchanges, and automatic exchanges.97 In addition, specific multilateral regional treaties authorize such a program. The bestknown examples are articles 2(a) and 8 of the OECD convention on mutual administrative assistance in tax matters,98 which expressly authorize simultaneous tax examinations. Article 12 of the Nordic convention on mutual assistance in tax matters is another example.99 All information obtained is treated as confidential under domestic laws and must be restricted to specific cases covered by the tax treaty or the mutual assistance agreement. The MNE concerned is normally notified of the SEP. 100 Under the SEP program, tax officials of the countries concerned meet and coordinate the audit examination of the MNE group. Often the MNE participates directly in the process in order to clarify factual issues, as mandated by domestic law. 101 93 For a discussion of taxpayers’ participation in the competent authority process, see Birnkrant and Cole, supra footnote 86, at 242-43. 94 Ibid. 95 OECD report, supra footnote 4, at paragraph 4.79. 96 Ibid., at paragraph 4.80. 97 Ibid. 98 OECD/Council of Europe Multi-National Convention on Mutual Administrative Assistance in Tax Matters, open for signature on January 25, 1988. 99 OECD report, supra footnote 4, at paragraph 4.79. 100 Ibid., at paragraph 4.83. 101 Ibid., at paragraph 4.85. (1998), Vol. 46, No. 1 / no 1 RESOLUTION OF INTERNATIONAL TRANSFER-PRICING DISPUTES 49 It is reported that the SEP enables tax administrations and taxpayers to arrive more effectively, efficiently, and quickly at satisfactory transfer prices.102 Often it culminates in early agreements and settlements, including any necessary corresponding adjustments, or at least it narrows down differences and permits early invocation of the mutual agreement procedure under applicable treaties. Safe Harbours Under statutory safe harbour (or safe haven) rules, certain intercompany transactions are excluded from the application of ordinary transfer-pricing methods (for example, by the setting of thresholds). Similar results could be achieved by simplified transfer-pricing rules, such as the setting of ranges of prices or profits for MNEs. The benefits of safe harbours are self-evident. They significantly ease compliance, afford a higher degree of flexibility where no comparables exist, and provide taxpayers with certainty, since transfer pricing in accordance with such rules must be accepted by the tax authorities. As well, tax administrations enjoy simplification of the auditing process.103 While recognizing these advantages, the OECD report did not recommend replacing the arm’s-length standard with a set of safe harbour rules. The report identified several drawbacks that outweigh the advantages.104 First, safe harbour rules are inconsistent with the arm’s-length standard, because for most intercompany transactions in MNE groups there are no readily available open market prices. For this reason, safe harbours tend to be arbitrary and do not correspond to the relevant facts and circumstances of the particular case. Second, MNEs would adjust their intercompany prices in order to comply with the rules of the country with the stronger tax administration, at the expense of other countries with weaker administrations. The result would be litigation when those countries tried to apply the arm’s-length standard, the possibility of double taxation for MNE s, and/or erosion of the domestic tax base. Consequently, to be effective, safe harbour rules would require high bilateral or multilateral coordination. Third, the OECD report suggested that safe harbours would naturally provide MNE s with tax-planning opportunities and might result in international underpayment of taxes by the diversion of a portion of the MNE’s income to low-tax or no-tax jurisdictions. 105 Fourth, subjecting taxpayers to two different sets of rules—the safe harbour rules and the arm’s-length rules—would be inequitable, and the lack of uniformity would result in discrimination and competitive distortions. 102 Ibid., Ibid., 104 Ibid., 105 Ibid., 103 at at at at paragraph 4.87. paragraph 4.100. paragraphs 4.103 to 4.120. paragraph 4.118. (1998), Vol. 46, No. 1 / no 1 50 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE Nevertheless, in my view, the adoption and acceptance of safe harbours should be seriously considered. Tax administrations of smaller countries or less developed economies cannot afford the allocation of resources needed in the transfer-pricing area, and even the most powerful country, the United States, constantly suffers from underpayment of taxes by MNEs under the current transfer-pricing regime. 106 Despite the clear drawbacks of safe harbours, they should not be ruled out by domestic legislatures. Such rules should be coupled with bilateral or multilateral accords in order to avoid international tax conflicts. Arbitration One of the most advanced mechanisms for resolving binational or multinational tax disputes, which also assists in avoiding double taxation, is arbitration. The concept of arbitration, as it is generally referred to in this discussion, covers binding arbitration as well as any kind of mediation or joint appointment of an advisory commission that would render its opinion on the specific solution for the elimination of double taxation in the given case. The best example thus far is the tax arbitration procedure embodied in the EC convention.107 It is instructive that the EC chose the area of transferpricing disputes to be covered by its innovative multilateral treaty (although in the EC framework). The EC convention introduces an arbitration procedure within the existing mutual agreement procedure of binational tax treaties. Although, to date, experience of implementing the EC convention has been negligible, it might increase. In fact, the UK Inland Revenue has recently published a notice considering the use of the EC convention as an alternative route to the mutual agreement procedure under UK bilateral tax treaties.108 The United Kingdom’s views might be shared and further developed by other members of the European Union as they gain experience in implementing the arbitration mechanism. Article 7 of the EC convention provides that whenever the competent authorities concerned fail within two years to reach an agreement that eliminates double taxation resulting from transfer pricing of intercompany transactions, they will set up an advisory commission that will deliver its opinion on the elimination of the double taxation concerned.

The decision may eliminate the double taxation concerned even if it deviates from the opinion handed down. 113 The proceedings are not subject to a statute of limitations under domestic laws. The substantive standards to be applied by both the advisory commission and the competent authorities are those of arm’s length as enunciated in the OECD model, which are incorporated in the EC convention. 114 The most important feature of the procedure is the binding power of the decision that resolves the dispute. Although the decision does not have the precedential value of a court decision, it may be published by the competent authorities.115 The arbitration procedure is very attractive, even in the binational context, and therefore has already been included in several tax treaties. Some examples follow. The Germany-Sweden tax treaty is unique in providing, in article 25A, that the European convention of 1957 for peaceful settlements of disputes applies. Alternatively, the parties may agree on arbitration by a council of arbitration whose decision will be binding on the parties.116 The council judges will be judges of the two states, or of third countries, or officials of international organizations. Taxpayers may present their case, and the substantive rules will be those of the tax treaties of the parties and of 109 Article 7(1) of the EC convention.

The appointment process should be completed in three months; otherwise, according to this treaty, appointments will be made by the Permanent Court of Arbitration. Substantive rules are also those of the tax treaty and international law. In this case also, the taxpayer may present its case, and the decision is binding. Recent treaties containing an arbitration clause continue the same trend, providing that upon the taxpayer’s consent, a case may be submitted to binding arbitration as an alternative or supplement to the mutual agreement procedure. The treaties provide that the taxpayer has right of hearing. Also, although the decision lacks precedential effect, it may be published and will be taken into account in future competent authority issues involving the same taxpayer. The US -Mexico treaty of 1992 contains provisions such as these. 120 It further prescribes that a protocol sets the procedures to be applied, including the requirement that the dispute will be submitted for arbitration if the competent authorities have not reached agreement within two years. Further procedures would be determined by the competent authorities. The substantive rules would be those of the treaty, “giving due consideration to domestic law” of the two states and the “principles of international law.” 121 A similar mechanism is contained in the US-Germany treaty of 1994, 122 which provides for procedures agreed upon through an exchange of notes. Again, the substantive rules are those of the treaty, giving due consideration to the domestic laws of both parties and the principles of international law. It is required that the decision be reasoned. Interestingly, the competent authorities may also submit a case to an independent commission in order to obtain an expert opinion instead of a decision.123 117 Ibid.

Thus, according to the 1992 US-Netherlands treaty, 124 the procedures are provided in a memorandum of understanding; however, these may be applied only when there is satisfactory experience with arbitration under the EC convention and the arbitration provision of the US-Germany treaty. Even then, recourse to arbitration is not compulsory. The Israel-Ireland treaty of 1995 provides in article 25(5) that if the competent authorities fail to reach agreement, upon their and the taxpayer’s consent, the case may be submitted to binding arbitration. Procedures are not specified but are expected to be established between both countries by an exchange of notes.125 The arbitration mechanism has been gaining support.126 In 1992, the OECD model, in its commentary on article 25, added arbitration as an alternative solution within the mutual agreement procedure along the lines of the EC convention,127 under which the competent authorities refer a dispute to binding arbitration. The International Chamber of Commerce (ICC) has strongly endorsed compulsory arbitration since 1984,128 as part of a wider resolution that envisages improvement of the general mutual agreement procedure. It supports obligatory referral to arbitration, with the taxpayer’s consent, if the competent authorities fail to reach agreement after one year. Each state would appoint a member to the arbitration commission, which in turn would choose an impartial chair. The decision would be based on the treaty rules, with right of hearing for the taxpayer, and the decision must be implemented despite domestic legal obstacles. The arbitration procedure could even be expanded in triangular cases to include a third country. Obviously, the ICC supports the European Union developments in this area. Even arbitration has its shortcomings, but these are outweighed by its advantages. Interestingly, the OECD Fiscal Affairs Committee, which at first opposed the use of arbitration in the transfer-pricing context, despite acknowledging its advantages, appears to have had second thoughts.129 In 124 Article 29(5).

(1998), Vol. 46, No. 1 / no 1 54 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE the light of recent developments, particularly in the OECD commentary on the model treaty and in the European Union, the committee has decided to re-evaluate its position following a study to be conducted in the near future. 130 The binding arbitration mechanism has many advantages: 131 • it enables a definite solution (if so prescribed) to double taxation following a deadlock in the treaty mutual agreement procedure; • it is relatively less expensive and more efficient than other techniques; • it could be fair to MNE s by granting them the right of hearing; • the arbitrators could be impartial experts who would be qualified to assess the pricing methodologies and all the economic factors critical to a satisfactory decision; and • it is up to the countries involved to decide whether to subject the procedure only to the arm’s-length norm and methods, or to leave room for greater flexibility to the arbitrators or the competent authorities on the basis of the arbitration findings. An example of resolving an international transfer-pricing dispute involving an MNE that operated in several countries was given domestically in the United States, when the Tax Court permitted, on the basis of its rule 124, a factual pricing dispute to be resolved by arbitration.132 The controversy related to the IRS’s allocation of income from Apple Singapore to Apple US, based on the arm’s-length methods applicable to Apple’s intercompany sales, services, and the use of intangibles. The case was decided by a panel of three arbitrators selected by the parties: a retired judge, a well-known economist, and an industry expert. CONCLUSION AND A PROPOSAL FOR BETTER TREATY SOLUTIONS Disputes over transfer pricing within MNE groups are the most important issue in international taxation today. On the one hand, tax administrations are concerned to impose an appropriate level of taxation on the global income of MNE groups and to achieve a proper division of that combined income among the participating countries. On the other hand, MNEs expect to be able to conduct their operations in the world economy without being subjected to double taxation, and with a reasonable degree of certainty and equity. 130 OECD report, supra footnote 4, at paragraph 4.171.

(1998), Vol. 46, No. 1 / no 1 RESOLUTION OF INTERNATIONAL TRANSFER-PRICING DISPUTES 55 Tax administrations have generally agreed to adopt the arm’s-length transactional norm as the main substantive standard applicable to transfer pricing, although differences remain regarding the specific methods to be applied in determining arm’s-length transfer prices. In my view, the focus of future developments should be shifted from the appropriate substantive methods to the appropriate mechanisms for resolving disputes between taxpayers and domestic tax administrations at the national level, and between national administrations and MNE groups at the international level. Such mechanisms have evolved at both the national and the international levels, as discussed previously. To my mind, the only practical way to provide such necessary mechanisms in the international arena is via binational tax treaties. In regional markets, such as the European Union, the Nordic countries, or even NAFTA countries, dispute resolution mechanisms could be designed to operate on a multilateral basis. The main treaty provision that affords the basis for dispute resolution mechanisms is the mutual agreement procedure of article 25 of the OECD model, applying the substantive standards of article 9 for associated enterprises and of article 7 for PEs, in conjunction with the exchange-of-information provision in article 26. Most bilateral tax treaties include articles similar to these provisions. It is proposed that the mutual agreement procedure should include one or more of the following mechanisms, according to the preferences of the treaty parties: • At the first level, the competent authorities and domestic tax administrations would encourage taxpayers to conclude APAs in order to resolve transfer-pricing issues in advance and on a case-by-case basis. This mechanism would facilitate attainment of the two objectives referred to above: the proper allocation of global income, and the accommodation of the need of MNEs for certainty and equity, without the risk of double taxation. The US model income tax treaty of 1996 emphasizes in article 25(3)(g) that the competent authorities may agree to apply the transfer-pricing methodology adopted in an APA . Article 25(3) of the OECD model generally covers APA s,133 but it is recommended that a more express reference be included in bilateral treaties, in conjunction with the exchange-of-information provision of article 26. APAs have been successfully developed domestically, and even BAPA s at the international level, with initially favourable responses from tax authorities and MNEs alike. However, they should be negotiated in a more flexible and simplified manner, thereby enabling the participation of mediumsized and small MNEs. Binational or multinational APA s are considered 133 Compare the OECD report, supra footnote 4, at paragraph 4.140. (1998), Vol. 46, No. 1 / no 1 56 CANADIAN TAX JOURNAL / REVUE FISCALE CANADIENNE much more effective than domestic APA s in reducing potential double taxation.134 The 1996 US APA procedure is a move in that direction. • At the second level, the SEP should be specifically included in bilateral treaties in order to facilitate information sharing between collaborating tax authorities and specifically the exchange of audit information pertaining to MNEs. This mechanism would reduce potential double taxation while enhancing the chances of resolving any remaining issues through the competent authorities. • At the third level, agreement on some limited safe harbours within the arm’s-length norm is desirable. It would ease compliance, afford flexibility, and provide certainty without the drawback of creating potential areas for double taxation when such rules are not uniform in the two countries. Safe harbour rules should play only a limited role in the transferpricing area because of their disadvantages, such as clear deviation from the arm’s-length standard and unjustified national tax losses. • At the fourth and final level, in my view, all treaties should provide for recourse to compulsory and binding arbitration, with the taxpayer’s consent, when the competent authorities cannot reach agreement to eliminate double taxation in a given case. This mechanism is to be used after a defined period from the time the case was referred to the competent authorities. The treaty or regulations thereunder, which would be concluded by an exchange of notes, should specifically provide rules concerning the substantive law and pricing methods to be selected, all the procedural aspects of the arbitration, and perhaps rules for limited judicial review in very rare situations. The arbitration mechanism set out in the EC convention could be adopted, 135 or any variation of its provisions in order to avoid some of its shortcomings. Thus, the competent authorities would create, for example, an advisory commission composed of the states’ appointees and an independent chair appointed by those state appointees or by the competent authorities. Within six months, the commission would deliver its reasoned decision on the exact method to be applied to eliminate double taxation. That decision would be binding on the states and the MNE. Alternatively, countries that strongly object to the surrender of national taxing power in this manner should agree that the competent authorities, within an additional six months, should adopt a decision that eliminates double taxation on the basis of the commission decision. It is advisable that the arbitration decisions be published, even without precedential effect, so as to ensure equity and uniformity. 134 135 Ibid., at paragraphs 4.146 and 4.163. See the text accompanying footnotes 107 to 115. (1998), Vol. 46, No. 1 / no 1 RESOLUTION OF INTERNATIONAL TRANSFER-PRICING DISPUTES 57 Hearing rights for all parties should be preserved. In addition, rules should ensure that the process prevails over any domestic procedural barriers and that it ends the dispute, either by a requirement of exhaustion of domestic remedies before its invocation or by the requirement that it is binding domestically. (For example, the taxpayer could sign a waiver of further litigation if the decision is valid under local law.) Substantive arbitration rules should be provided for, on the basis of the treaty substantive rules, while giving due consideration to the domestic laws of the two countries and to international tax law norms. The main novel feature of the proposed arbitration mechanism, as compared with that in the few tax treaties that have already adopted such a solution, is not only its specific procedures and its efficiency, but the fact that it is compulsory. Thus, it would end the dispute at issue and assure the elimination of any double taxation. It is contended that the mere fact that rules of compulsory arbitration are added to tax treaties would strongly encourage the competent authorities of the countries involved to resolve the dispute before the invocation of this avenue of last resort. Thus, an arbitration mechanism would serve a useful purpose even if it were not invoked in practice. It is further proposed that the OECD model be amended to include a compulsory and binding arbitration mechanism. The other noted mechanisms could be recommended or mentioned in the OECD model commentary. Indeed, acceptance of the arbitration alternative would gain momentum if the OECD Fiscal Affairs Committee recommended it in the committee’s ongoing study of transfer pricing pursuant to the OECD report.136 136 See supra footnote 130 and accompanying text.
