In the first three posts in this series, I explored how early decisions shape DOJ investigations, influence credibility, and affect the trajectory of a matter.

Those themes lead naturally to another concept that is frequently discussed but often misunderstood: cooperation.

When most people hear the term, they think about cooperation credit, negotiations with DOJ, or the resolution of an investigation. By that point, however, DOJ has often been evaluating cooperation for months.

In practice, cooperation is not a single decision. It is a series of choices that begin long before anyone starts discussing "cooperation."

Cooperation Starts Earlier Than Companies Think

Companies often view cooperation as a question that arises after misconduct has been identified and an investigative strategy has been developed.

From DOJ's perspective, the analysis typically starts much sooner.

When an issue surfaces, prosecutors pay attention to how an organization responds. Does it preserve evidence? Does it investigate thoroughly? Does it distinguish between known facts and assumptions? Does it follow facts where they lead, even when the answers are uncomfortable?

Long before there are conversations about cooperation credit, DOJ is observing conduct that informs its assessment.

Cooperation Is Not the Same as Agreement

Another common misconception is that cooperation requires agreeing with DOJ's view of the facts. It does not.

Companies can disagree with the government's theories, challenge its conclusions, and advocate for their positions while still being viewed as cooperative.

The more important question is whether the organization is engaging in a credible and constructive process.

A company that investigates thoroughly, presents facts accurately, and communicates candidly may be viewed as cooperative even when significant disagreements exist. Conversely, an organization that appears disorganized, defensive, or inconsistent may create concerns even if it ultimately reaches the same conclusions as DOJ.

What DOJ's Recent Guidance Reveals

DOJ's recent policy guidance reinforces this point.

In March 2026, DOJ released a new department-wide Corporate Enforcement Policy for criminal matters. In announcing the policy, DOJ emphasized incentives for companies that voluntarily disclose misconduct, cooperate with investigations, and appropriately remediate wrongdoing. The Department's message was notable not simply because of the incentives offered, but because of what those incentives reward. Disclosure, cooperation, and remediation all begin long before a matter reaches resolution.

Why This Matters

Enforcement priorities change. Policies evolve. Public discussion about prosecutorial discretion continues.

What remains remarkably consistent is DOJ's focus on whether an organization can be trusted to investigate responsibly, communicate candidly, and respond appropriately when issues arise.

Like credibility, cooperation is rarely built through a single action. It is earned through a series of decisions that demonstrate discipline, transparency, and a willingness to follow the facts wherever they lead.
