The ties that bind: Knowledge-seeking networks and auditor job performance

The dissemination of knowledge in audit firms is a critical process that has gone relatively unexamined by researchers. Using social network analysis to quantify the knowledge-seeking networks in a Big 4 audit firm in the U.S., we examine the association between the types and patterns of knowledge-seeking ties and individual auditor performance. Our initial finding is that auditor job performance is negatively associated with the number of knowledge-seeking ties. Further, our analyses demonstrate that this negative association is being driven by explicit knowledge-seeking rather than tacit knowledge-seeking activities and is stronger for higher-ranked auditors. Thus, knowledge-seeking by auditors may come at a cost, particularly when that knowledge is codifiable and when the seeking is done by those at higher levels of the firm. In a post-hoc analysis, we find that tacit knowledge-seeking ties to managers can be beneficial for auditor performance, and tacit knowledge-seeking ties to senior managers and partners is sometimes detrimental. In sum, this suggests that who is seeking knowledge and who is being sought for knowledge are both important for performance. Our findings may assist researchers to better understand how auditors leverage their social connections to learn, which in turn may affect audit efficiency and effectiveness. Further, audit firms might benefit from better understanding the consequences of knowledge-seeking from different sources and use this understanding to make decisions that maximize desirable information flows

Audit firm tenure, non-audit services and internal assessments of audit quality

We use data from internal assessments of audit quality in a Big 4 firm to investigate the impact of audit firm tenure and auditor-provided non-audit services (NAS) on audit quality. We find that first-year audits receive lower assessments of audit quality and that quality improves shortly thereafter and then declines as tenure becomes very long. Partitioning our sample between SEC registrants and private clients, we find that the decline in audit quality in the long tenure range is attributable to audits of private clients. For audits of SEC registrants, the probability of a high quality audit reaches its maximum with very long tenure. We also find that audit fees are discounted for first-year audits but auditor effort is higher than in subsequent years. We find no association, on average, between total NAS fees and audit quality in the full sample but observe that total NAS fees are positively associated with quality for SEC registrants and negatively associated with quality for privately held clients. Our findings are important for regulatory policies related to audit firm tenure and auditor-provided NAS

Auditors’ Quantitative Materiality Judgments: Properties and Implications for Financial Reporting Reliability

We analyze data made available through the PCAOB (Public Company Accounting Oversight Board) to provide descriptive evidence on the properties of auditors' actual quantitative materiality judgments and the implications of those judgments for financial reporting. Auditors' quantitative materiality judgments do not appear to result simply from applying conventional rules of thumb (e.g., 5% of pretax income), but instead are associated with size-related financial statement outcomes (income, revenues, and assets), where the relative importance of the size-related outcomes varies with client characteristics such as financial performance. Using the distribution of actual materiality amounts reported by auditors to the PCAOB as part of the audit-inspection process, we construct a materiality-judgment measure that locates a specific materiality amount within a normal range that is both comparable across varying client characteristics and supported by guidance in audit firm internal policy manuals. We find that looser materiality (an amount closer to the high end of a normal materiality range) is associated with fewer audit hours and lower audit fees, supporting the construct validity of this measure. We also find that looser materiality is associated with lower amounts of proposed audit adjustments and, in extreme cases, with a greater incidence of restatements, highlighting the importance of auditor materiality assessments for financial reporting reliability.12 month embargo; published online: 3 July 2019This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

The Business Risk Audit Approach and Audit Production Efficiency

Essentially, this study asks: Does the business risk audit (BRA) approach increase audit production efficiency? To answer this question empirically, direct and indirect tests are employed using proprietary, working paper data from the larger clients of a major Australian public sector audit provider and an efficiency frontier analytic methodology, data envelopment analysis (DEA). Results based on this proprietary, audit hours data for audit engagements carried out just after BRA approach implementation show that they have high levels of production efficiency and are risk-adjusted, with no significant difference in production efficiency between higher and lower business risk audit engagements. Results based on audit fees data for audit engagements carried out shortly before and after BRA approach implementation show that overall production efficiency significantly improves. Importantly, while this improvement is significant for lower-risk audit engagements, there is no significant improvement for higher-risk audit engagements. In the context of this study's research site, this is consistent with the BRA approach addressing inefficiencies created when lower-risk audit engagements are being over-audited. That is, the BRA approach can result in both risk-adjusted and more efficiently produced audits. With the re-emergence of the BRA approach in the literature and in practice, this study provides empirical evidence to support the claim that this audit approach can lead to 'creating auditing efficiencies' (Bell et al., 1997, p. 1)
