Earnings management on the JSE before and after King II

Abstract

This research investigated whether earnings management of listed companies, have increased or decreased since the implementation of King II in 2003. This study assessed the extent of earnings management for certain sectors and for large and mid cap companies. The discretionary component of total accruals was used as proxy for earnings management – calculated by using the Modified Jones Model. The top-100 JSE-listed firms by market capitalisation were assessed, excluding the Financial, Mining and Resource Sectors. It was found that discretionary accruals has increased since 1996 and peaked in 2005 (see graph Figure 13). It was concluded with 89% certainty that discretionary accruals during “2003-2009” were higher than during “1996-2002”. Hence, the research suggests that accrual based earnings management is likely to have increased since 2003. However, the results were not statistically significant. Also, the cause of this increase could be due to many factors (not necessarily due to King II). Discretionary accruals were found to be higher for mid cap companies and for the retail sector. However, the analysis was not statistically significant. Discretionary accruals have fluctuated significantly over time and amongst companies. In order to identify which companies and sectors manage earnings the most, a more detailed micro-level investigation, using multiple detection models, is required. Copyright
