Rule 10b5-1 Trading Plans Explainer
A Rule 10b5-1 trading plan is a written arrangement that specifies future securities transactions through a formula, schedule, or independent decision process. When adopted and operated under the rule’s conditions, it can provide an affirmative defense to certain insider-trading claims.
The person must enter the plan when not aware of material nonpublic information and must act in good faith rather than using the plan as a scheme to evade the rule. The plan must remove later discretion over whether, when, or at what price covered trades occur.
Current requirements include cooling-off periods for directors and officers, certifications, limits on overlapping plans and some single-trade plans, and issuer disclosure about plan adoption and termination. A material modification can be treated like ending and adopting a new plan.
A plan is not automatic immunity. Manipulation, selective cancellation, false certifications, or possession and misuse of information outside the plan can create liability. Investors should read company disclosures and distinguish scheduled plan sales from discretionary transactions while still evaluating incentives and ownership.
