Wim Janssen †

Assistant Professor

Wim Janssen is Assistant Professor of Financial Accounting at the University of Amsterdam and a researcher at the Foundation for Auditing Research, affiliated with Nyenrode Business University. He obtained his PhD in Accounting from Tilburg University, where his dissertation explored the interaction between tax enforcement and audit practices. His research focuses on corporate disclosures, audit quality, financial reporting under tax incentives, and governance mechanisms. Wim has published on topics such as auditor reporting behavior in bankruptcy contexts and the societal impact of audit enforcement, and he regularly collaborates on projects examining audit quality and regulatory compliance.He teaches graduate-level courses in financial accounting and research methodology and contributes to the development of evidence-based insights for regulators and practitioners. Wim has presented his work to the European Commission and professional bodies such as the Dutch Institute of Chartered Accountants (NBA), bridging academic research with policy and practice. His recent projects include studies on going-concern opinions, audit failures, and the role of technology in auditing.

The team studied the reporting behavior of Dutch organizations subject to statutory audit in the three years prior to their bankruptcy. They found that only 12 percent of companies file timely audited financial statements or an exemption in the year prior to bankruptcy, 56 percent (64) in year two (three) before the bankruptcy. Second, management discloses discontinuity risks in just 29 percent of the pre-bankruptcy filing. And third, only 11 percent of organizations have a filed audit opinion for the fiscal year prior to bankruptcy. However, for the majority (63 percent or 39 instances out of 62) of audit opinions issued for the fiscal year before the insolvency, the auditor did not include a material uncertainty relating to going concern (GCO) in its audit opinion and therefore constitute a type-II GCO error (error of omission). They estimate the total GCO type-II (I) error rate at 0.03 (99.26) percent of audit opinions issued.

According to the AFM Monitor, approximately 19,333 statutory audit opinions were issued in the Netherlands in 2019. However, which organizations received these opinions for which reports, and whether this information is publicly available, has not yet been systematically mapped. At the same time, there is a growing need for information about audit quality for the market as a whole. For financial statement users, policymakers, and other stakeholders, it is not always clear which audits fall under the Audit Firms Supervision Act (Wta) and thus under AFM oversight. In this descriptive article, we estimate the number of Wta audits and whether these are publicly accessible. Of all statutory audits, 18,311 opinions (95%) are publicly available through various sources, such as the Chamber of Commerce.
Large audit firms typically ‘‘offshore’’ simple and repetitive audit tasks such as reconciliations to shared service centers. Offshoring however comes at the expense of coordination costs, delays in the process, and challenges regarding the liability risk to the auditor. This paper presents an open-source algorithm to extract data from (draft) annual reports (PDF files) using Python to automate, rather than outsource, the data extraction for reconciliations. The algorithm resulted in a significant time saving for the audit of a large Dutch asset management firm. Researchers apply the algorithm to minimize hand-collection of financial statement data. Data Availability: The algorithm this paper presents is open-source and publicly available. It was a joint project with Jeroen Bellinga, Seyit Hocuk, Wim Janssen and Alaa Khzam. Wim Janssen and Alaa Khzam developed the programming code.   Article AAA
