The aim of this study was to evaluate whether changes in accounting practices brought reduction in earnings management of listed Brazilian non-financial companies, resulting in improvement of quality in accounting information. A sample of non-financial Brazilian companies (361 firms) was used. Data were collected at the website of the CVM or at the website of the companies, when necessary. To measure earnings management through discretionary accruals Jones Model and KS Model were applied, including the internationally used variations of these models and the use of polynomial equations. A model developed in this study was used to observe the effect of IFRS on earnings management of firms in periods Full- IFRS and Hybrid, and the restrictive effects of Big Four audit, corporate governance and regulatory environment. The results of earnings management were considered through discretionary accruals obtained by residues of the models that had better information as statistical results: Model Jones polynomial; Modified Jones Model by Kothari, Leone and Wasley (2005) original polynomial and omitting accounts receivable; Modified Jones Model by Teoh, Welch and Wong (1998) with the omission of the polynomial variation of accounts receivable and inclusion of ROA; and Model KS polynomial. Evidence was found that convergence to IFRS had a restrictive effect on earnings management in Brazil after the complete implementation of IFRS. Among the factors constraining earnings management studied by Big Four audit, corporate governance and regulatory environment, it was noted that the most effective is the regulatory environment. Entities, whose industry is regulated by a regulatory agency in addition to the CVM, have lower levels of earnings management than the others. It was also noted that the larger the company the lower is the level of earnings management. It is noteworthy that the process of convergence to IFRS in Brazil is recent, this way, this work was limited to short coverage periods of these standards. Given this limitation, it is suggested that more research would be conducted to examine earnings management in IFRS in Brazil in later periods, to validate the results obtained by this work, maintaining the reduced use of discretionary appropriations in light of IFRS in Brazil.
