Identificação de manipulação de resultados segundo o modelo de Dechow e Dichev (2002)

Abstract

This essay was made with the purpose to identify earning management taken from the accruals accounts reported by the companies. For that effect, the Dechow & Dichev model (2002) has been used, with the main objective of evaluate its ability of identifying real cases. This evaluation was carried out through a two-stage procedure. On the first stage, results were estimated based on accounts reported by 12 294 american companies during 1987-2014 time frame, a measure of discretionary accruals made by each company, year upon year, according to Dechow & Dichev model (2002). On the second stage, as an example, one compared the estimation of discretionary accruals related to year 2013 with the identification of the companies listed by the Securities and Exchange Commission (SEC) as if they had manipulated accounts that same year. The results sugest that 76% of the companies identified by SEC present discretionary accruals estimations above average (and median) of all entreprises’ discretionary accruals that entire year. That said, Dechow & Dichev model (2002) may be considered a good model for identifying earning management.
