Rule 10b5‑1 is a Securities and Exchange Commission (SEC) rule that allows corporate insiders to adopt prearranged, written trading plans for buying or selling company securities while avoiding insider‑trading liability — provided certain conditions are met. It creates an affirmative defense to a Rule 10b‑5 insider‑trading charge when trades are made under a plan that was entered into in good faith and when the plan’s terms limit the insider’s ability to control the timing of trades while in possession of material nonpublic information (MNPI).
Key takeaways
– Purpose: to permit scheduled, preplanned insider trades while reducing the risk of insider‑trading accusations.
– Who it affects: company officers, directors, >10% shareholders, other insiders with access to MNPI, and companies using structured repurchases or vulnerability‑prone programs.
– Core requirement: plans generally must be written, adopted when the adopter is not aware of MNPI, and specify amounts/timing or a nondiscretionary method for determining trades.
– Recent reforms: the SEC adopted amendments (Dec. 2022) that increase disclosure and add conditions (including a cooling‑off period and required certifications). Settlement cycles for equities moved to T+1 in 2024, which affects timing and recordkeeping for trades.
Why Rule 10b5‑1 exists (purpose)
– Clarifies how insiders can lawfully sell or buy company stock without relying on contemporaneous judgments while in possession of MNPI.
– Provides an affirmative defense to Rule 10b‑5 securities fraud claims if trades conform to a valid 10b5‑1 plan.
– Helps companies and investors understand that certain insider trades were preplanned and not based on undisclosed material information.
Who is affected
– Insiders of public companies: executive officers, directors, controlling or >10% shareholders, and other persons who possess MNPI.
– Brokers and trading counterparties that implement plans.
– Public companies that adopt insider trading policies, administer plan approvals, or use 10b5‑1 arrangements in buybacks.
Core features of a valid 10b5‑1 plan
Although the details can vary, a compliant plan typically has these features:
– Written: the plan must be documented in writing.
– Adopted in the absence of MNPI: the insider must not be aware of MNPI about the issuer or its securities at the time the plan is adopted.
– Predetermined or formulaic: the plan must specify either fixed amounts, specific dates, or a clear, objective formula (for example, a VWAP algorithm or periodic sales) for determining the amount, price, and timing of transactions.
– No ongoing discretion: once the plan is in effect, the insider should not retain the ability to exercise subsequent influence over how, when, or whether to execute trades covered by the plan.
– Respect amended rules: follow any additional conditions imposed by the SEC amendments (e.g., certifications, cooling‑off requirements, and disclosure rules).
What changed under the SEC’s amendments (Dec. 2022) — summary
– Increased public and agency disclosure requirements about 10b5‑1 plans and related insider trades.
– Added conditions to the availability of the 10b5‑1 affirmative defense, including required certifications that the person adopting the plan is not aware of MNPI and is acting in good faith.
– Imposed a cooling‑off period between plan adoption and the first trade under many plans (the final rule sets the specific requirements).
– Expanded recordkeeping and certification obligations for the person adopting the plan and for brokers carrying out certain trades.
– These reforms were intended to address concerns that some insiders used overlapping or back‑dated plans or exploited gaps in the prior rule to trade while aware of MNPI.
Practical steps for insiders who want to use a 10b5‑1 plan
1. Review company policy and securities law counsel
• Before doing anything, confirm the company’s insider trading policy and consult securities counsel to ensure compliance with the current SEC rules and any firm governance requirements.
2. Confirm you are not aware of MNPI
• Do a contemporaneous check to confirm you do not possess MNPI about the company or its securities at the time you adopt the plan. Document that check (see recordkeeping below).
3. Choose plan type and mechanics
• Decide whether to use periodic fixed sales, fixed‑amount sales, limit orders, VWAP/volume‑based algorithms, or a combination. Specify price, volume, frequency, and duration, or provide a non‑discretionary formula.
4. Put it in writing and include required certifications
• Draft a written plan that sets out all material terms, including start and end dates (if any), how amounts/prices are determined, whether cancellations are permitted, and any broker instructions. Include any attestations required under current SEC rules (e.g., certification of absence of MNPI and good‑faith adoption).
5. Allow required cooling‑off and timing rules to elapse
• Observe any mandated cooling‑off period between plan adoption and the first trade. (Consult counsel and the final SEC rule text for the exact permitted timing and any company‑specific minimums.)
6. Coordinate with your broker
• Execute the plan with your broker and ensure the broker understands it must follow plan parameters and document instructions. The broker’s role and any certifications it must make should be documented.
7. Avoid amending or terminating while aware of MNPI
• Don’t materially modify, suspend, or terminate a plan while you are aware of MNPI. If you must terminate or amend, consult counsel to understand the legal and disclosure implications.
8. Maintain contemporaneous records
• Keep copies of the written plan, the pre‑adoption MNPI absence check, counsel and broker communications, certifications signed, and any plan modifications or terminations. Good records support the affirmative defense.
9. Report and disclose as required
• File required insider trading forms (Forms 3, 4, 5, or Schedule 13D/G as applicable) and follow any company disclosure protocols. The SEC’s amendments increased certain disclosure expectations — and many companies announce adoption of plans voluntarily to mitigate PR risk.
10. Monitor and comply with post‑trade procedures
• Track executed trades, settlement dates (now T+1 for most equity trades), and report on the required forms. Ensure trades executed under a plan remain within the plan’s parameters.
Practical steps for companies (policy, governance, and oversight)
– Adopt or update a written insider trading policy that incorporates the SEC’s amended requirements and specifies how 10b5‑1 plans will be approved and documented.
– Implement a centralized registry of 10b5‑1 plans, with copies of plans, adoption dates, certifications, and broker agreements.
– Require preclearance and approval for plan adoption for executives and other covered persons; consider independent review for CEO and CFO plans.
– Prohibit or limit overlapping plans and stacking of multiple concurrent plans by the same insider.
– Train executives and directors on timing, recordkeeping, the meaning of MNPI, and the company’s plan approval process.
– Design disclosure practices (including voluntary announcements) to reduce market confusion and reputational risk.
– Coordinate insider plan administration with the company’s legal, compliance, and payroll teams (especially if plans interact with compensation programs or tax withholding).
Common plan types (examples)
– Fixed schedule: sell a specified number of shares on specific dates (e.g., 5,000 shares on the second Wednesday of each month).
– Fixed amount per period: sell a fixed dollar amount or number of shares monthly or quarterly.
– Formulaic/VWAP: instruct broker to execute trades referenced to VWAP or another objective benchmark over a specified window.
– Limit orders or price thresholds: sell only if the price reaches or exceeds a stated price.
Risks, enforcement, and practical cautions
– The affirmative defense is not automatic. If the SEC or a court finds the plan was adopted in bad faith, back‑dated, or used to conceal trades made while knowing MNPI, the defense can be lost and enforcement pursued.
– Overlapping or serial plans and frequent amendments have attracted regulatory scrutiny. Companies and insiders should avoid practices that could be perceived as exploitative.
– Even if lawful, trades under 10b5‑1 plans can create reputational issues; many firms encourage voluntary public disclosure of plan adoption for transparency.
– Keep in mind changes in market settlement cycles (e.g., transition to T+1) when modelling timing and recordkeeping for trades.
Recordkeeping and evidence to preserve
– Copy of the written plan and the broker agreement.
– Date/time stamped evidence that the insider was not aware of MNPI when the plan was adopted (e.g., email showing no meetings/updates, written attestation).
– Counsel memos and approvals, preclearance forms, and compliance signoffs.
– Broker confirmations of orders and trade executions, and any broker certifications required under the rule.
– Forms filed with the SEC (Forms 3/4/5 and any relevant disclosures).
Example checklist for adopting a 10b5‑1 plan
1. Review company insider trading policy and SEC guidance.
2. Confirm absence of MNPI; document the check.
3. Decide plan type (fixed, periodic, VWAP, limit, etc.).
4. Draft written plan specifying all terms and include required attestations.
5. Consult legal counsel and obtain preclearance from compliance.
6. Observe any cooling‑off period before the first execution.
7. Execute plan with broker and obtain broker’s acknowledgements.
8. File necessary insider reporting forms and consider public disclosure.
9. Keep centralized, dated records supporting the plan’s legitimacy.
10. Do not amend/terminate while aware of MNPI; if necessary, seek counsel.

Bottom line
Rule 10b5‑1 enables insiders and companies to put in place preestablished trading arrangements that, if properly structured and adopted free of MNPI, provide an affirmative defense to insider‑trading allegations. Recent SEC amendments strengthen documentation, certification, disclosure, and timing requirements, so insiders and companies should update policies, work with counsel, and maintain robust recordkeeping and approval processes before adopting or amending plans.
