Abstract: Purpose - This study aims to examine the effect on audit efficiency of outsourced internal audit function (IAF) providers with industry and/or firm-specific expertise. Drawing on relevant studies from external and internal audit literature, the authors assume that such IAF providers are associated with greater audit efficiency as proxied by audit report lag and audit fees. Design/methodology/approach - Based on a sample of firms listed on the Omani capital market during 2005–2019, the pooled regressions are used to test the developed hypotheses. The authors use the market share approach to identify outsourced IAF industry expertise providers and tenure to measure the firm-specific expertise of outsourced IAF providers. Findings - The authors find that industry outsourced IAF providers are not associated with shorter audit report lag and lower audit fees. The authors also find that firm-specific expertise outsourced IAF providers are associated with a greater reduction in audit report lag and audit fees. These conclusions are robust under a battery of analyses. The significant contribution of firm-specific expertise outsourced IAF providers to audit efficiency is incremental when abnormal audit report lag and audit fees analysis is conducted. Originality/value - The results are the first to attest to the contribution of outsourced IAF with firm-specific expertise. They also show that industry expertise held by outsourced IAF providers does not contribute to audit efficiency.
