Abstract
Purpose - The purpose of this study is to examine the effect of the audit committee (AC) independence, financial expertise, internal audit function, audit quality and ownership concentration on earnings quality (EQ) and, consequently, ascertain whether the AC's independence and financial expertise has a moderating effect on the relationship between internal audit function and EQ.
Design/methodology/approach - The study sample is 508 firms listed on the Main Market of Bursa Malaysia (formerly known as Kuala Lumpur Stock Exchange) for the years 2009 to 2012. EQ was measured using two modified Jones models of discretionary accruals.
Findings - The findings reveal that the independence of AC and investment in internal audit function, as well as the Big4 audit firm, are related to greater EQ. Ownership concentration is found to be associated with lower EQ. The study provides evidence that AC's independence moderates the relationship between internal audit function (investment in and sourcing arrangements of internal audit function) and EQ. It also shows that AC's financial expertise moderates the relationship between sourcing arrangements of internal audit function and EQ.
Practical implications - This study extends the prior related literature by examining the AC's independence and financial expertise as moderating variables on the relationship between internal audit function and EQ.
Social implications - Policymakers might use the findings regarding EQ in relation to governance practices, to recognize the important roles played by the AC's independence and financial expertise on the effectiveness of internal audit function with EQ.
Originality/value - This study uses the agency theory and resource dependence theory to provide empirical evidence on the impact of internal audit function and AC on EQ in the ownership concentration environment.
