The Central District of California recently shut down, on preemption grounds, a group of class-action plaintiffs’ second attempt to assert claims alleging that benzoyl peroxide (BPO) in over-the-counter (OTC) acne treatments unavoidably degrades into the carcinogen benzene.

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.
