Enron and the endless repair of audit

A company failed, a major audit firm unravelled and oversight changed. Why is declaring audit fixed still so difficult?

The familiar version has three acts. Enron collapses. Arthur Andersen unravels. Congress repairs the system.

It is an efficient way to remember 2001–2002. It is a less satisfactory way to understand what happened to auditing afterwards.

Enron filed for bankruptcy in December 2001. In its subsequent account of enforcement work, the SEC described allegations involving entities made to appear independent of Enron and transactions used to improve its reported financial results.^{Note 1} The scandal challenged the credibility of the information on which investors had relied.

The damage extended to the company’s auditor. Andersen’s collapse as a major audit practice helped turn the Big Five into the Big Four. One legal qualification belongs in any responsible telling: the Supreme Court reversed Andersen’s obstruction conviction in 2005. The conviction should not be described as a final, enduring judicial verdict.^{Note 2}

There was no equivalent reversal of the profession’s reputational crisis.

The auditor acquires an inspector

The Sarbanes–Oxley Act became law on 30 July 2002. Among its major changes was the creation of the Public Company Accounting Oversight Board. The new framework provided for registration, standard-setting, inspection and disciplinary work under SEC oversight.^{Note 3}

That was a substantial institutional change. It subjected audit firms to a dedicated external oversight structure and challenged the idea that the profession could provide sufficient assurance about itself through its existing arrangements.

It would be wrong, however, to describe the period before 2002 as a world without law, regulators or sanctions. The securities-law history of the 1930s alone rules that out. The change concerned the architecture and intensity of oversight, not the discovery that auditors had public responsibilities.

It would be equally misleading to make Enron the only cause of reform. Other failures, including WorldCom, formed part of the crisis. A single famous name is a convenient label for a much wider loss of confidence.^{Note 4}

What counts as a repair?

Derek Matthews’s history of British auditing traces changes in work over a much longer period: changing techniques, clients, economics and technology. That perspective helps resist the idea that an audit method begins or ends neatly with a scandal.^{Note 4}

Christopher Humphrey and his co-authors press the question further. They argue that repeated reforms have tended to improve or regulate the delivery of an established audit model while leaving its underlying purpose relatively untouched. Their proposed “dynamic repair” asks whether audit’s form and social contribution should themselves be reconsidered.^{Note 5}

That is an argument, not a finding that all regulation has failed. Inspection can expose weaknesses. Enforcement can impose consequences. Standards can clarify expectations. The harder point is that those achievements do not settle every question about what people need from an audit.

If readers expect an opinion to guarantee a company’s survival, a more rigorously executed financial-statement audit will not automatically resolve the mismatch. Nor does explaining limitations answer every legitimate concern about whether the service could be more useful.

The question after the new procedure

Consider a hypothetical firm responding to a difficult inspection by adding another approval to an audit file. The change might be valuable if the reviewer has time, expertise and authority to challenge the work. It might achieve little if approval becomes another box completed shortly before the deadline.

The distinction is between the existence of a procedure and the effect it has on judgement.

For an audit committee, the corresponding inquiry is concrete: what changed in how difficult issues were investigated? Did contrary evidence reach the right people? Were estimates challenged more effectively? Did a problem get resolved, or merely acquire more documentation?

Those questions are harder than counting the number of new rules. They are also closer to the public reason for having the rules.

Enron belongs in the history of audit because it changed institutions and expectations. Its lasting challenge is to resist making reform itself the happy ending. A repair earns that description through what the repaired system can do.
