The Administrative Council of Economic Defense – CADE released, during their 81st trial session held on March 16th, 2016, a preliminary version of their Guide on the Analysis of Horizontal Concentration Acts. The Guide aims to “give greater transparency to the analysis carried out by the authority; orientate public authorities to adopt best antitrust practices on the matter; and help players in the market understand the phases, techniques and criteria adopted by Cade in their analysis of horizontal mergers”. Although it is not binding nor obligatory, the document reflects CADE’s current vision on the matter of merger review, being that the methodology that will be used by the authority will depend on the peculiarities of the matter at hand. This Guide is undergoing public consultation and contributions regarding its content will be received until April 30th, 2016; suggestions should be sent to the email: guiah@cade.gov.br.
