Abstract: Purpose - This paper aims to examine the extent to which two commonly recommended information sharing and communication interventions, direct reporting lines between the internal audit function (IAF) and the audit committee (AC) and their joint reviews of internal audit standards and procedures, improve the internal audit in the continuous audit control and monitoring efforts. Design/methodology/approach - This study uses data from the Audit Intelligence Suite-Benchmarking (AIS) Report for the years 2007 to 2016 published by the Institute of Internal Auditors. The authors test the research hypotheses using the ordinary least squares regression method. Findings - Functional reporting lines from the IAF to the AC positively impact the internal audit, but administrative lines have a negative impact. Reviews conducted jointly between the IAF and the AC positively influence the internal audit. The impacts of reporting lines and joint reviews are also associated with accounting complexity within a given industry, organizational control structure, organizational scope and the level of IAF’s responsibilities over internal control environment to comply with Sarbanes–Oxley (SOX) Act of 2002. Research limitations/implications - Because the study uses AIS data, operationalization of variables is constrained to items in the given data set. Future studies, including field studies, may identify other variables and measures using diverse data sources. This study expands the knowledge of effective means of information sharing and communication to enhance interactions between the IAF and the AC. Practical implications - The results suggest that the use of reporting lines should correspond to accounting complexity, organizational control structure, organizational scope, and reliance on the IAF in handling SOX responsibilities. They also highlight the importance of joint reviews between the IAF and AC in ensuring a high-quality internal audit. Originality/value - The authors envisioned reporting lines and joint reviews as an excellent tool to balance the relationship between the IAF and the AC for continuous internal auditing beyond generating internal audit reports according to the US Committee of Sponsoring Organizations of the Treadway Commission framework Principle 14.
