Having spent almost fifty years of my life defending the separate accou- ing, arms length pricing method, I have to admit that I was somewhat surprised to be asked to contribute to a book suggesting that the European Union might do well to consider adopting a formulary approach to deal with the taxation of inter and intra company transactions. I was even more surprised to see the invitation coming from Ms. Joann Weiner an ardent co-defender of arms length pricing and my strong right arm in that regard while we both served in the U.S. Treasury Department in the mid 90s. The book gives Ms Weiner the opportunity to comment frankly from an insiders perspective of the many admitted problems of the arms length system which could be avoided by a formulary approach. Ms. Weiner brings to this project a thorough expert knowledge of the b- efits and shortfalls of each of the systems she discusses - separate accounting v. formulary apportionment. Who better to decide to give qualified support to formulary than someone who organized a U.S. Treasury conference to defend arms length pricing against a Congressional challenge in favor of formulary apportionment.
