Rule 10b5-1 Trading Plans: What You Need to Know

For many corporate insiders, trading company stock isn’t as simple as placing an order with a broker. Executives, directors, and other employees with access to material nonpublic information (MNPI) must navigate strict insider trading laws designed to protect the fairness and integrity of U.S. securities markets.

This is where Rule 10b5-1 trading plans come in.

Rule 10b5-1 plans provide a structured mechanism that allows insiders to buy or sell company stock—even at times when they may later come into possession of MNPI—without violating insider trading laws. For stock plan administrators and legal professionals responsible for insider trading compliance, these plans are a critical tool for managing executive equity transactions and minimizing regulatory risk.

Below is a practical overview of how Rule 10b5-1 trading plans work, why companies rely on them, and what compliance teams need to monitor. To learn more about 10b5-1 plans, check out our article “Understanding 10b5-1 Plans.”

What to know how 10b5-1 plans work at other companies? The NASPP pulse survey, “Executive Equity Services and Trends,” provides data on company policies for 10b5-1 plans.

The Role of 10b5-1 Plans in Insider Trading Policies

Most public companies maintain insider trading policies that establish trading windows and blackout periods. These windows typically open shortly after earnings releases and remain closed during much of the quarter.

For senior executives and directors—who often possess MNPI even when trading windows are open—this can severely limit opportunities to trade.

Rule 10b5-1 trading plans provide a workaround. Because the trading instructions are established in advance, trades can occur automatically under the plan even during closed trading windows.

This allows insiders to:

• Spread transactions over time
• Avoid large one-time stock sales
• Diversify their holdings
• Address liquidity needs tied to equity compensation

For stock plan administrators, these plans also simplify the logistics of scheduled stock sales related to equity awards, such as tax withholding transactions or option exercises.

Core Requirements for Rule 10b5-1 Trading Plans

To qualify for the rule’s protections, trading plans must meet specific SEC requirements. Many companies impose additional restrictions through internal policies.

Written Trading Plan

A Rule 10b5-1 plan must be established in writing and adopted when the insider is not aware of MNPI.

The plan must specify:

• The amount of securities to be traded (or a formula to determine it)
• The price and timing of the transactions
• Instructions that prevent the insider from influencing trades after adoption

Once implemented, the insider cannot exercise discretion over the transactions.

Cooling-Off Period Requirements

Another important compliance feature is the cooling-off period—the waiting period between plan adoption and the first trade.

Under current SEC rules:

• Section 16 officers and directors must wait until the later of:
• 90 days after adopting the plan, or
• Two business days after the company files its Form 10-Q or Form 10-K for that quarter
• Other employees and investors must observe a 30-day cooling-off period.

Limits on Overlapping Plans

The SEC also restricts insiders from maintaining multiple trading plans that execute trades during the same period.

Without this restriction, insiders could theoretically establish multiple plans with different trading schedules and cancel the ones that become unfavorable based on new information.

However, a new plan can overlap with an existing one as long as trades under the second plan do not begin until the first plan is completed and the applicable cooling-off period has passed.

Restrictions on Single-Trade Plans

To address concerns about potential abuse, the SEC also limits the use of single-trade 10b5-1 plans.

Insiders may adopt only one single-trade plan during any 12-month period.

Exception for Shares Sold to Cover Taxes Due on Equity Awards

There is an important exception to the restrictions on overlapping and single-trade plans: plans used solely to sell shares to cover tax withholding on restricted stock or RSU vesting events are not subject to these limits.

Good Faith and Certification Requirements

Rule 10b5-1 plans must be adopted in good faith, and insiders must continue to act in good faith throughout the life of the plan.

Additionally, Section 16 officers and directors must certify that:

• They are not aware of material nonpublic information at the time the plan is adopted.
• The plan is not part of a scheme to evade insider trading prohibitions.

These certifications reinforce accountability and emphasize the insider’s responsibility to follow insider trading rules.

SEC Disclosure Requirements for 10b5-1 Plans

Rule 10b5-1 trading plans also carry specific disclosure obligations.

Form 4 and Form 5 Reporting

When insiders report transactions on Forms 4 or 5, they must:

• Indicate that the transaction occurred under a Rule 10b5-1 plan by selecting the Rule 10b5-1 checkbox on the form
• Disclose the date the plan was adopted

Quarterly Company Disclosure

Public companies must also disclose certain details about insider trading plans in their Forms 10-Q and 10-K, including:

• The names and titles of insiders adopting plans
• Plan adoption, modification, or termination dates
• Plan duration
• The aggregate number of securities covered by the plan

What This Means for Stock Plan Administrators

For stock plan administrators, Rule 10b5-1 plans intersect directly with equity compensation administration and insider trading compliance.

Key responsibilities often include:

• Coordinating plan adoption with the company’s insider trading policy
• Monitoring cooling-off periods and plan limitations
• Ensuring Form 4 reporting and disclosure requirements are satisfied
• Helping executives understand how trading plans interact with equity awards

As SEC oversight of insider trading continues to evolve, companies are paying closer attention to how these plans are structured and administered.

For compliance teams and equity plan professionals alike, a strong understanding of Rule 10b5-1 trading plans is essential to maintaining transparency, protecting executives, and reinforcing trust in the public markets.
