(i) USP, a U.S. corporation, manufactures Product X, an unbranded widget, and sells it to FSub, its wholly owned foreign subsidiary. FSub acts as a distributor of Product X in country M, and sells it to uncontrolled parties in that country. Uncontrolled distributors A, B, C, D, and E distribute competing products of approximately similar value in country M. All such products are unbranded. (ii) Relatively complete data is available regarding the functions performed and risks borne by the uncontrolled distributors and the contractual terms under which they operate in the uncontrolled transactions. In addition, data is available to ensure accounting consistency between all of the uncontrolled distributors and FSub. Because the available data is sufficiently complete and accurate to conclude that it is likely that all material differences between the controlled and uncontrolled transactions have been identified, such differences have a definite and reasonably ascertainable effect, and reliable adjustments are made to account for such differences, the results of ...

The degree of consistency in accounting practices between the controlled transaction and the uncontrolled comparables that materially affect the gross profit margin affects the reliability of the result. Thus, for example, if differences in inventory and other cost accounting practices would materially affect the gross profit margin, the ability to make reliable adjustments for such differences would affect the reliability of the results. Further, the controlled transaction and the uncontrolled comparable should be consistent in the reporting of items (such as discounts, returns and allowances, rebates, transportation costs, insurance, and packaging) between cost of goods sold and operating expenses ...

The reliability of the results derived from the resale price method is affected by the completeness and accuracy of the data used and the reliability of the assumptions made to apply this method. See § 1.482-1(c) (Best method rule) ... Read more

Deficiencies in the data used or assumptions made may have a greater effect on some methods than others. In particular, the reliability of some methods is heavily dependent on the similarity of property or services involved in the controlled and uncontrolled transaction. For certain other methods, such as the resale price method, the analysis of the extent to which controlled and uncontrolled taxpayers undertake the same or similar functions, employ similar resources, and bear similar risks is particularly important. Finally, under other methods, such as the profit split method, defining the relevant business activity and appropriate allocation of costs, income, and assets may be of particular importance. Therefore, a difference between the controlled and uncontrolled transactions for which an accurate adjustment cannot be made may have a greater effect on the reliability of the results derived under one method than the results derived under another method. For example, differences in management efficiency may have a greater effect on a comparable ... Read more

All methods rely on certain assumptions. The reliability of the results derived from a method depends on the soundness of such assumptions. Some assumptions are relatively reliable. For example, adjustments for differences in payment terms between controlled and uncontrolled transactions may be based on the assumption that at arm’s length such differences would lead to price differences that reflect the time value of money. Although selection of the appropriate interest rate to use in making such adjustments involves some judgement, the economic analysis on which the assumption is based is relatively sound. Other assumptions may be less reliable. For example, the residual profit split method may be based on the assumption that capitalized intangible development expenses reflect the relative value of the intangible property contributed by each party. Because the costs of developing an intangible may not be related to its market value, the soundness of this assumption will affect the reliability of the results derived from this method ...

The completeness and accuracy of the data affects the ability to identify and quantify those factors that would affect the result under any particular method. For example, the completeness and accuracy of data will determine the extent to which it is possible to identify differences between the controlled and uncontrolled transactions, and the reliability of adjustments that are made to account for such differences. An analysis will be relatively more reliable as the completeness and accuracy of the data increases ... Read more

Whether a method provides the most reliable measure of an arm’s length result also depends upon the completeness and accuracy of the underlying data, the reliability of the assumptions, and the sensitivity of the results to possible deficiencies in the data and assumptions. Such factors are particularly relevant in evaluating the degree of comparability between the controlled and uncontrolled transactions. These factors are discussed in paragraphs (c)(2)(ii) (A), (B), and (C) of this section ... Read more

Data based on the results of transactions between unrelated parties provides the most objective basis for determining whether the results of a controlled transaction are arm’s length. Thus, in determining which of two or more available methods (or applications of a single method) provides the most reliable measure of an arm’s length result, the two primary factors to take into account are the degree of comparability between the controlled transaction (or taxpayer) and any uncontrolled comparables, and the quality of the data and assumptions used in the analysis. In addition, in certain circumstances, it also may be relevant to consider whether the results of an analysis are consistent with the results of an analysis under another method. These factors are explained in paragraphs (c)(2)(i), (ii), and (iii) of this section ... Read more

The identification of potential comparables has to be made with the objective of finding the most reliable data, recognising that they will not always be perfect. For instance, independent transactions may be scarce in certain markets and industries. A pragmatic solution may need to be found, on a case-by-case basis, such as broadening the search and using information on uncontrolled transactions taking place in the same industry and a comparable geographical market, but performed by third parties that may have different business strategies, business models or other slightly different economic circumstances; information on uncontrolled transactions taking place in the same industry but in other geographical markets; or information on uncontrolled transactions taking place in the same geographical market but in other industries. The choice among these various options will depend on the facts and circumstances of the case, and in particular on the significance of the expected effects of comparability defects on the reliability of the analysis ...
