DOJ Declines Prosecution of PE Firm – Lessons for International Trade Violations and Beyond

In a significant decision announced last week, the Department of Justice (DOJ) declined to prosecute a private equity (PE) firm after the firm voluntarily disclosed sanctions and export control violations committed by a portfolio company the firm acquired. This result, and the government’s joint enforcement actions against the portfolio company and its former CEO, offer several important takeaways:


• It is critical for PE firms to conduct robust, non-siloed due diligence for trade and other compliance both before and after acquisition.

• Sanctions and export controls enforcement remains a key government focus, as evidenced by the extensive behind-the-scenes coordination between Justice, Treasury, Commerce, and Homeland Security.

• It is not uncommon for private equity firms to acquire a company and then discover hidden problems. Firms that promptly investigate, self-report, cooperate, and remediate can avoid criminal prosecution, even for serious violations.

• The government continues to hold individuals personally responsible for violations of sanctions and export controls regulations.
