When I first learned about this event, a retrospective of a nearly 20-year-old cartel investigation seemed like a slightly odd subject. But then it occurred to me that this event offers an opportunity — not just to look back, but to think about how much enforcement has evolved and what’s on the horizon. Of course, over the decades we’ve kept the same core principles at the heart of our work: individual accountability, encouraging self-reporting and good corporate citizenship and, fundamentally, promoting competition and open markets. But while those principles have stayed the same, it’s not an exaggeration — though maybe it’s a cliché — to say almost everything else has changed.
