Resumo: The objective of this paper is to verify the level of adherence to the requirements of CPC 22 – (IFRS 8) Segment Information. Besides serving to harmonize accounting rules to Brazilian GAAP, applying this standard by listed companies reveals information that would not be possible only through the consolidated statements. We examined the notes and reference form of the 150 Brazilian largest companies. 36 of these companies offered conditions to verify the disclosure of information by segment. We opted for an exploratory research, which was attributed to note the presence of each item required to disclose. The results showed a good level of disclosure, although only 8 companies have disclosed all required information. The information that all companies were reported was types of products and services, income and information and main customer. The other side, the segment information were disclosed less about liabilities and the explanations of the measurement bases. As this CPC is a new standard in Brazil, it is expected that further research be done, given the importance of the subject in relation to the objectives of accounting.
