In practice, it has been observed that comparability analyses for methods based on gross or net profit indicators often put more emphasis on functional similarities than on product similarities. Depending on the facts and circumstances of the case, it may be acceptable to broaden the scope of the comparability analysis to include uncontrolled transactions involving products that are different, but where similar functions are undertaken. However, the acceptance of such an approach depends on the effects that the product differences have on the reliability of the comparison and on whether or not more reliable data are available. Before broadening the search to include a larger number of potentially comparable uncontrolled transactions based on similar functions being undertaken, thought should be given to whether such transactions are likely to offer reliable comparables for the controlled transaction ...

Depending on the transfer pricing method, this factor must be given more or less weight. Among the methods described at Chapter II of these Guidelines, the requirement for comparability of property or services is the strictest for the comparable uncontrolled price method. Under the comparable uncontrolled price method, any material difference in the characteristics of property or services can have an effect on the price and would require an appropriate adjustment to be considered (see in particular paragraph 2.16). Under the resale price method and cost plus method, some differences in the characteristics of property or services are less likely to have a material effect on the gross profit margin or mark-up on costs (see in particular paragraphs 2.29 and 2.47). Differences in the characteristics of property or services are also less sensitive in the case of the transactional profit methods than in the case of traditional transaction methods (see in particular paragraph 2.75). This however does not mean that the question of comparability in characteristics of property or services can be ignored when applying transactional profit methods, because it may be that product differences entail or reflect different functions performed, assets used and/or risks assumed by the tested party. See paragraphs 3.18–3.19 for a discussion of the notion of tested party ...

Differences in the specific characteristics of property or services often account, at least in part, for differences in their value in the open market. Therefore, comparisons of these features may be useful in delineating the transaction and in determining the comparability of controlled and uncontrolled transactions. Characteristics that may be important to consider include the following: in the case of transfers of tangible property, the physical features of the property, its quality and reliability, and the availability and volume of supply; in the case of the provision of services, the nature and extent of the services; and in the case of intangible property, the form of transaction (e.g. licensing or sale), the type of property (e.g. patent, trademark, or know-how), the duration and degree of protection, and the anticipated benefits from the use of the property. For further discussion of some of the specific features of intangibles that may prove important in a comparability analysis involving transfers of intangibles or rights in intangibles, see Section D.2.1 of Chapter VI ...
