Antitrust Leniency Program: An Inside Look at Its Genesis and Impact

Lisa Phelan, a partner at Morrison Foerster, offers a unique perspective on the origins and effectiveness of the U.S. government's antitrust corporate leniency program. Having spent over two decades prosecuting antitrust crimes at the Department of Justice, Phelan was instrumental in developing this initiative approximately thirty years ago. The program was conceived to overcome the inherent challenges of proving criminal antitrust cases, which often rely on employees reporting their superiors, a difficult prospect given job security concerns. This innovative approach provides immunity from prosecution for companies and their executives who are the first to report the existence of a cartel and fully cooperate with investigators.

The leniency program created a powerful incentive for insiders to come forward, particularly given the potential for multi-million dollar fines associated with cartel participation. Initially, there was uncertainty about how defense counsel would react to voluntarily admitting client wrongdoing, but the significant value for companies quickly became apparent. This led to a surge in companies self-reporting their involvement in criminal cartels, often while the illegal conduct was still ongoing. Such cooperation provided investigators with invaluable evidence, including video and audio recordings of price-fixing meetings, which frequently resulted in swift plea agreements.

The success of the program has been self-reinforcing, with companies observing the severe penalties faced by non-cooperating entities in high-profile cases, such as the airline industry, and choosing to seek leniency. The program distinguishes between Type A applicants, who report cartels unknown to the DOJ, and Type B applicants, who come forward after an investigation has already begun. Even in Type B scenarios, insider cooperation remains highly valuable, especially for international cartels where obtaining documents from foreign countries can be challenging. The program has significantly aided the resolution of a majority of large cartel cases since the late 1990s.
