There are five internatlionally accepted TP methods: CUP; Resale price; Cost plus; TNMM; and transactional profit split. There is also a "sixth" method used by some developing countries, of which Brazil is a good example. This chapter deals with the methods based on extensive examples taken from the UN practical manual. It also describes these methods in terms of the transacting parties' profit and loss accounts to enhance a deeper understanding of the practicalities surrounding such choices.
