Abstract

This study examines the impact of internal audit outsourcing and internal audit’s involvement in consulting on external auditors’ reliance on the work of internal audit. We test whether these factors influence (i) reliance on internal audit work already undertaken and (ii) the use of internal auditors as assistants. In each case, we distinguish between control evaluation and substantive testing. We find that involvement in consulting impacts reliance on work undertaken and the use of internal auditors as assistants for control evaluation. External auditors make greater use of internal auditors as assistants for substantive testing when internal audit is provided in-house. Overall, external auditors use internal audit more for control evaluation tasks than for substantive testing.
