The United States is poised to relax key provisions of the Sarbanes-Oxley Act, nearly 25 years after the high-profile collapse of energy giant Enron exposed widespread corporate accounting fraud. The upcoming changes, proposed by the Securities and Exchange Commission (SEC), aim to reduce the regulatory burden on public companies by scaling back auditor attestation requirements for internal financial controls.

Enron’s bankruptcy in 2001 revealed that the company had manipulated its financial statements, prompting Congress to enact the Sarbanes-Oxley Act in 2002 to enhance corporate governance and financial transparency. A critical component of the law has been the requirement for most publicly traded companies to obtain an independent auditor’s certification of their internal controls, providing an additional safeguard against accounting malpractice.

However, this attestation mandate has long been contentious due to its associated costs and complexity. Critics, including Paul Atkins—currently chair of the SEC and formerly an SEC commissioner—have argued that auditors often spend excessive time reviewing numerous low-risk procedures, inflating audit expenses without proportionate benefits. Since the law’s introduction, regulatory reforms have gradually narrowed the number of companies subject to this requirement, and the new SEC proposal seeks to exempt an even larger group.

Under the proposal, all publicly traded companies with a market capitalization below $2 billion would be exempted from auditor attestation of internal controls. Additionally, companies of any size would be free from this requirement during their first five years after going public, which could include sizable firms. The SEC maintains that the remaining roughly 1,100 issuers still subject to the rule represent 94 percent of total market capitalization, thereby preserving investor protections for the bulk of market value.

Proponents argue the change will encourage more companies to pursue initial public offerings by lowering compliance costs and administrative hurdles. The US Chamber of Commerce and the Nasdaq stock exchange have publicly supported the move, citing concerns that current rules are disproportionately expensive and may discourage capital formation. Conversely, investor advocacy groups and some audit firms have opposed the proposal over fears it could weaken oversight and potentially increase financial misstatements.

Data from Ideagen Audit Analytics indicates that companies exempt from auditor attestation currently account for 60 to 80 percent of financial restatements each year and report internal control deficiencies more frequently. Previous studies cited by the SEC also found auditors’ involvement often uncovers material weaknesses that management alone might understate. While estimating the exact cost savings from the exemption is challenging, a Government Accountability Office report last year placed the reduction in audit fees between 13 and 19 percent, potentially totaling $400 million to $600 million across all affected companies.

The broader implications on investor confidence and overall capital market integrity remain uncertain. The SEC has encouraged exploring alternative measures to reduce compliance costs without broadly exempting companies, such as issuing revised guidance to auditors to streamline attestation processes.

As the US approaches the quarter-century mark since Enron’s collapse, the debate continues over how best to balance regulatory safeguards with market efficiency to prevent a recurrence of past financial scandals.
