The comparability analysis is at the heart of the application of the arm’s length principle. Application of the arm’s length principle is based on a comparison of the conditions in a controlled transaction with the conditions that would have been made had the parties been independent and undertaking a comparable transaction under comparable circumstances. There are two key aspects in such an analysis: the first aspect is to identify the commercial or financial relations between the associated enterprises and the conditions and economically relevant circumstances attaching to those relations in order that the controlled transaction is accurately delineated; the second aspect is to compare the conditions and the economically relevant circumstances of the controlled transaction as accurately delineated with the conditions and the economically relevant circumstances of comparable transactions between independent enterprises.
