A move away from the arm’s length principle would abandon the sound theoretical basis described above and threaten the international consensus, thereby substantially increasing the risk of double taxation. Experience under the arm’s length principle has become sufficiently broad and sophisticated to establish a substantial body of common understanding among the business community and tax administrations. This shared understanding is of great practical value in achieving the objectives of securing the appropriate tax base in each jurisdiction and avoiding double taxation. This experience should be drawn on to elaborate the arm’s length principle further, to refine its operation, and to improve its administration by providing clearer guidance to taxpayers and more timely examinations. In sum, OECD member countries continue to support strongly the arm’s length principle. In fact, no legitimate or realistic alternative to the arm’s length principle has emerged. Global formulary apportionment, sometimes mentioned as a possible alternative, would not be acceptable in theory, implementation, or practice. (See Section C, immediately below, for a discussion of global formulary apportionment.)
