It’s time to reform the Big Four accounting firms

It has been exactly 20 years since the Enron scandal upended the reputation of global accountancy firms, leading to the downfall of both the company – one of the largest in US history up to that point – and Arthur Andersen, one of the ‘Big Eight’ accounting firms.

Enron’s collapse provoked an avalanche of regulation, ostensibly to reduce the chances of similar accounting fraud repeating itself. In the United States this effort was spearheaded by the 2002 Sarbanes–Oxley Act, while the European Union’s 2006 Auditing Directive followed scandals like the 2003 collapse of Italian dairy giant Parmalat.

In reality, these supposedly stringent regulations were crafted under considerable influence from the big accountancy firms themselves, which have since consolidated into the ‘Big Four’.

As the Belgian chartered accountant Peter Vandewalle wrote in 2010: ‘In fact, the working methods of the four big accountancy firms (Deloitte, KPMG, Ernst & Young and PriceWaterhouseCoopers) have been largely enshrined into legislation, despite the fact their approach failed when it came to Enron [and] Parmalat.’

As Vandewalle laid out over a decade ago, the types of rules enshrined by the EU in 2006 – still in force in the UK – primarily benefited the big players in the accountancy market, who can marshal far greater resources to handle compliance obligations than smaller competitors.

Each new scandal reveals how conflicts of interest between Big Four accounting firms and the clients who pay them fails investors and helps disguise corporate fraud

More recent scandals impacting all four major consulting giants have helped demonstrate his point, making it painfully clear that despite all the extra regulatory burdens, the EU, UK, and US have still not figured out how to effectively combat large-scale accounting fraud.

Take, for example, the Wirecard scandal in Germany. While the Financial Times was raising questions about the company’s balance sheet as early as 2015, the DAX-listed German payment processor was able to continue engaging in suspected fake transactions and potentially fraudulent accounting activities until it finally went bankrupt in June 2020.
