No. of bitstreams: 1 Adalene Olivia Silvestre_.pdf: 590609 bytes, checksum: 188661a0ac02964a45900cec5e4c0062 (MD5) Previous issue date: 2016-12-20 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / PROSUP - Programa de Suporte à Pós-Gradução de Instituições de Ensino Particulares / A auditoria independente exerce um importante papel na relação entre a empresa e os usuários externos à entidade, devendo o auditor ser independente em relação à empresa auditada. No Brasil, o rodízio obrigatório de firma de auditoria é regulamentado pela Instrução CVM 308/99 na tentativa de contribuir com a manutenção da independência do auditor e, consequentemente, com a qualidade dos lucros divulgados pelas empresas. Diante disto, o presente estudo tem por objetivo analisar o efeito do rodízio da firma de auditoria sobre a qualidade dos lucros das empresas de capital aberto brasileiras listadas na BM&FBOVESPA no período de 2008 a 2015. Como medida de qualidade dos lucros foram utilizados os accruals residuais, que identificam a parcela discricionária dos accruals, medida inversa à qualidade dos lucros. Os accruals residuais foram abordados a partir de duas diferentes perspectivas: o gerenciamento de resultados, medido pelos modelos de Jones (1991) e Jones Modificado por Dechow, Sloan e Sweeney (1995) e os erros de estimativas, medidos pelos modelos de Dechow e Dichev (2002) e Dechow e Dichev modificado por McNichols (2002). Os resultados demonstram que o rodízio de firma de auditoria reduz o volume de accruals residuais e, assim, aumenta a qualidade dos lucros, quando esses são mensurados a partir da perspectiva do gerenciamento de resultados, através dos modelos de Jones e Jones modificado. Entretanto, o efeito do rodízio de firma de auditoria sobre a qualidade dos lucros não é observado quando os accruals residuais são mensurados a partir da perspectiva dos erros de estimativas contábeis, através dos modelos de Dechow e Dichev e McNichols. Por outro lado, os resultados demonstram que as empresas que realizam rodízio voluntário de firma de auditoria apresentam maiores accruals residuais e, consequentemente, menor qualidade dos lucros. / Independent audit plays an important role in the relationship between the company and external users, and the auditor must be independent of the audited company. In Brazil, the mandatory audit firm rotation is regulated by CVM Instruction 308/99, in an attempt to contribute to the maintenance of auditor independence and, consequently, with the quality of earnings disclosed by the companies. Therefore, the present study has the objective of analyzing the effect of the audit firm rotation on the earnings quality of Brazilian public companies listed on BM&FBOVESPA in the period from 2008 to 2015. Residuals accruals were used as a measure of earnings quality, which identify a discretionary portion of the accruals, inverse measure of earnings quality. The residuals accruals were approached from two different perspectives: earnings management, measured by Jones model (1991) and Jones modified by Dechow, Sloan and Sweeney model (1995) and the estimation errors, measured by the Dechow and Dichev model (2002) and Dechow and Dichev modified by McNichols model (2002). The results show that audit firm rotation reduced the volume of residuals accruals and, thus, increases the earnings quality, when these are measured from the perspective of earnings management through the Jones and Jones modified models. However, the effect of audit firm rotation on the earnings quality is not observed when the residuals accruals are measured from the perspective of accounting estimation errors, through the Dechow and Dichev and McNichols models. On the other hand, the results demonstrate that the companies that perform the voluntary audit firm rotation have greater residuals accruals and, consequently, lower earnings quality.
