IAC in this study comprises four factors namely, qualifications of the chief audit executive, size,
qualification and experience of the audit department. Generally, the previous study dedicated to
examining the relationship between internal audit and firm performance is so limited in both
developed countries and developing countries. Several studies have called for further studies to
conduct extensive investigations; for instance, Hutchinson and Zain (2009), explored the association
between internal (audit experience and accounting qualification) audit and firm performance (ROA)
with growth opportunities and audit committee independence in the context of Malaysia. Their study
has two future recommendations. First, future studies should examine the role of the board and the
interaction between internal audit quality and audit committee independence. Secondly, this study
encourages future studies to look into alternate models of factors that would possibly impact IAQ and
improve corporate governance
