Corporate governance is expected to watch over the transparency of the accounting information that is presented to the public. In that sense, corporate governance codes propose the creation of the board of administrators and, for support, the audit committee. This study aims to compare the proposed characteristics of the audit committee in the corporate governance code of Brazil and other countries. A qualitative research was undertaken through content analysis of the corporate governance laws of 17 countries that report audit committee characteristics. In addition, the application of the audit committee characteristics proposed in Brazil by the Brazilian Corporate Governance Institute (IBGC) was analyzed in companies from the State of Santa Catarina whose stock is traded on the Sao Paulo Stock Exchange. The results show similarities in the proposed audit committee characteristics among the countries under analysis, particularly in the composition, qualification of the members and responsibilities. What the implementation of the proposed audit committee in the companies from Santa Catarina is concerned, the majority presents a fiscal council instead of an audit committee. In conclusion, despite the similarities in the characteristics of the audit committees identified in the corporate governance codes, further research is needed to create a pattern for regulatory entities to propose to the companies.
