Research limitations/implications

– The research has contributed to the agency theory with respect to the bonding costs that management has to pay to the internal auditors for the best interest of the principals of the companies. Another important implication pertains to the extent of the internal auditing practices among internal auditors in Malaysian public listed companies. Research has also shown that the compliance with internal auditing practices partially influence certain aspects of the quality of the internal control system.
– This is the first empirical study that has linked the compliance of the internal auditing function to the SPPIA and its effect on the internal control system.
