Os efeitos da auditoria independente (externa) sobre a manipulação da informação contábil por parte das OPS brasileiras

Resumo

This research aims to investigate whether the external (independent) audit minimizes the propensity for manipulation of accounting information (measured by discretionary current accruals) by health maintenance organizations (OPS), in regard to financial information disclosed to the Brazilian Health Care Agency (ANS). Based on a literature review of external audit, manipulation of accounting information and health care industry we developed an empirical research to information provided by OPS to the ANS for the period 2004 to 2006. To test for significant differences in the level of discretionary current accruals, measured by AWCA model and modified Jones (1995), we compared the quality of audited information (fourth quarter of each year) with the quality of non-audited information (the first three quarters of each year) from the same companies. This difference was investigated by the nonparametric Mann-Whitney test. The results indicate that there are no statistically significant differences in the propensity to manipulation of accounting information between audited and non-audited financial reports, at least in relation to information from 2004 to 2006 provided by OPS to the ANS. In addition, there were also tested the influence of type of procedure, size of firm and the situation presented in shareholders' equity on the discretionary current accruals. It was observed that these three variables influence a greater or lesser degree in the manipulation of accounting information generated by the OPS to the ANS. In this context, the following features on the more likely the MIC were diagnosed: Cooperative Dental and Medical Group (Type of Procedure); Small (Size of Firm); and Negative Equity or close to zero (Situation Presented in Shareholders’ Equity). On the other hand, the main features that are less likely to MIC were: Cooperative Medical and Philanthropy (Type of Procedure); Medium and large (Size of Firm); and Equity Favorable (Situation Presented in Shareholders’ equity).
