Arthur Andersen was once one of the world’s most respected professional services firms, renowned for its rigorous approach to auditing and ethics. Founded in Chicago in 1913, the firm grew into one of the “Big Five” accounting firms, advising many of the largest corporations in the UK, the USA and beyond. Its reputation was built on independence and technical excellence, making its eventual collapse all the more striking. In the broader history of accounting, Arthur Andersen had long been cited as a model of professionalism, and in the history of auditing it was associated with uncompromising standards and robust internal controls. In both the history of accounting and the history of auditing, Arthur Andersen stood as a benchmark for quality until its dramatic fall.
The firm’s downfall is inseparable from the Enron scandal of the early 2000s. Arthur Andersen served as Enron’s auditor and was accused of failing to challenge the company’s aggressive accounting practices. When Enron collapsed in 2001, investigators discovered that Andersen staff had destroyed documents related to the audit, raising serious concerns about obstruction of justice. This scandal highlighted the dangers of conflict of interest when a firm provides both auditing and lucrative consulting services to the same client, a lesson echoed repeatedly in the history of accounting and the history of auditing. The controversy reached into the specifics of audit workpapers, as questions emerged about the handling, retention, and destruction of those audit workpapers during the Enron engagement.
Why did Arthur Andersen collapse after the Enron scandal? The immediate catalyst was the charge and subsequent 2002 conviction for obstruction of justice related to document destruction, which shattered market confidence. Even before formal penalties took effect, clients fled and counterparties questioned the reliability of Arthur Andersen’s audits. The scandal exposed perceived weaknesses in internal controls at the firm itself, not just at Enron, and intensified scrutiny of conflict of interest risks inherent in combining audit and advisory work. In short, the scandal triggered a rapid loss of trust, a run on the franchise, and a breakdown of its global partnership, pushing Arthur Andersen into collapse. In the history of auditing, few events demonstrate so starkly how quickly confidence can evaporate when independence and internal controls are questioned, especially amid allegations of obstruction of justice.
Was Arthur Andersen’s conviction overturned? Yes. In 2005, the US Supreme Court unanimously overturned Arthur Andersen’s 2002 conviction for obstruction of justice, finding that the jury instructions were flawed. However, the reversal arrived too late to save the firm. By then, the scandal had driven away clients and partners, the global network had unravelled, and the business was no longer viable. Thus, although the conviction was overturned, the practical consequences of the scandal—particularly the reputational damage tied to document destruction and the handling of audit workpapers—had already inflicted irreparable harm. This outcome is a cautionary chapter in the history of accounting, underscoring that reputational contagion can be fatal even if legal outcomes change later. It also reinforced, in the history of auditing, that preserving audit workpapers and avoiding any perception of obstruction of justice are essential to sustaining trust.
How did the Arthur Andersen scandal reshape global auditing and governance? The fallout accelerated regulatory reform and sharpened expectations around auditor independence, internal controls, and corporate oversight. In the United States, the Sarbanes–Oxley Act established the Public Company Accounting Oversight Board, mandated stronger internal controls over financial reporting, tightened audit workpaper retention rules, and restricted services that could create a conflict of interest for auditors. Globally, standard-setters and regulators revisited the history of auditing to draw lessons on documentation, quality control, and the segregation of audit and consulting. Companies strengthened audit committees, enhanced oversight of auditors, and elevated the importance of transparent internal controls. The scandal also renewed focus on independence safeguards meant to prevent conflict of interest, and it reinforced the critical role of preserving audit workpapers to support audit conclusions and deter obstruction of justice. These changes are now embedded in the modern history of accounting and continue to influence practice worldwide.
In retrospect, Arthur Andersen’s trajectory—from exemplar to emblem of failure—marks a pivotal point in the history of accounting and the history of auditing. The scandal demonstrated how ethical lapses, weak internal controls, and real or perceived conflict of interest can undermine public trust. It also showed that once confidence is lost—especially amid accusations of obstruction of justice—no subsequent legal vindication can easily restore it. For practitioners and businesses alike, the enduring lesson is clear: rigorous documentation of audit workpapers, robust internal controls, and unwavering independence are foundational to audit credibility and to the resilience of the profession.
