For many years, German tax authorities suspected that M.N.C.’s transfer pricing policies were not in line with the arm’s length principle. Consequently, it comes as no surprise that Germany spearheaded international regulatory developments related to the arm’s length standard. International M.N.C.’s face ever increasing tax controversies in matters related to transfer pricing. In some cases, T.N.M.M. benchmarking is challenged under the view that a German sales entity makes intangible-related D.E.M.P.E. contributions in the field of marketing. In other cases ,C.U.T. benchmarking for intercompany license fees is challenged on grounds that the intangible property licensed to a German affiliate is unique by definition, thereby leading to a profit split. Restructures are attacked using inflated values for routine activities that remain in Germany. However, all is not bleak. In three case studies, Dr. Yves Herve, a Senior Managing Director in the Frankfurt Office of NERA and Philip de Homont, MSc, a Managing Director in the Frankfurt Office of NERA, illustrate in “plain language” the ways by which in-depth economic analysis has been used to overcome aggressive assertions by tax examiners.
