10b5-1 Plan

SEC Rule 10b5-1 creates a legal safe harbor for corporate insiders, executives, directors, and others who regularly possess material non-public information. By establishing a written plan when they are not aware of inside information, and specifying in advance the amounts, prices, and timing of future trades, insiders can allow those trades to execute automatically even during periods when they might otherwise possess sensitive information. The plan, not the individual, makes the trading decision at execution time.

For families where one or more members hold senior roles at a public company, a 10b5-1 plan is sometimes evaluated as the primary mechanism for converting restricted or control stock into diversified wealth over time. Without such a plan, an executive's ability to sell may be confined to narrow windows, creating significant concentration risk. Plans are subject to regulatory requirements including mandatory cooling-off periods between plan adoption and first trade; the specific rules have evolved over time and should be confirmed with qualified securities counsel.

A common misconception is that establishing a plan guarantees immunity from scrutiny. Regulators may still examine whether the plan was adopted in good faith and whether it has been improperly amended or canceled. Families dealing with these rules should also understand blackout periods and Rule 144, which layer additional constraints on insider sales. Legal counsel specializing in securities compliance is essential.
