Global formulary apportionment has been promoted as an alternative to the arm’s length principle by advocates who claim that it would provide greater administrative convenience and certainty for taxpayers. These advocates also take the position that global formulary apportionment is more in keeping with economic reality. They argue that an MNE group must be considered on a group-wide or consolidated basis to reflect the business realities of the relationships among the associated enterprises in the group. They assert that the separate accounting method is inappropriate for highly integrated groups because it is difficult to determine what contribution each associated enterprise makes to the overall profit of the MNE group.
