Taxpayers do not always perform searches for comparables on a jurisdiction-by-jurisdiction basis, e.g. in cases where there are insufficient data available at the domestic level and/or in order to reduce compliance costs where several entities of an MNE group have comparable functional analyses. Non-domestic comparables should not be automatically rejected just because they are not domestic. A determination of whether non-domestic comparables are reliable has to be made on a case-by-case basis and by reference to the extent to which they satisfy the five comparability factors. Whether or not one regional search for comparables can be reliably used for several subsidiaries of an MNE group operating in a given region of the world depends on the particular circumstances in which each of those subsidiaries operates. See paragraphs 1.132-1.133 on market differences and multi-jurisdictional analyses. Difficulties may also arise from differing accounting standards ...

In cases where similar controlled transactions are carried out by an MNE group in several countries and where the economic circumstances in these countries are in effect reasonably homogeneous, it may be appropriate for this MNE group to rely on a multiple-country comparability analysis to support its transfer pricing policy towards this group of countries. But there are also numerous situations where an MNE group offers significantly different ranges of products or services in each country, and/or performs significantly different functions in each of these countries (using significantly different assets and assuming significantly different risks), and/or where its business strategies and/or economic circumstances are found to be significantly different. In these latter situations, the recourse to a multiple-country approach may reduce reliability ...
