Following this original 1979 publication, the OECD Transfer Pricing Guidelines were approved by the OECD Council in their original version in 1995. A limited update was made in this 2009 edition, primarily to reflect the adoption, in the 2008 update of the Model Tax Convention, of a new paragraph 5 of Article 25 dealing with arbitration, and of changes to the Commentary on Article 25 on mutual agreement procedures to resolve cross-border tax disputes. A subsequent edition was released in 2010, in which, Chapters I-III were substantially revised, with new guidance on: the selection of the most appropriate transfer pricing method to the circumstances of the case; the practical application of transactional profit methods (transactional net margin method and profit split method); and on the performance of comparability analyses. Furthermore, a new Chapter IX, on the transfer pricing aspects of business restructurings, was added. Consistency changes were made to the rest of the Guidelines.
