Company trading windows and insider trading policies control when company stock can be sold, how much can be sold, and which strategies are available at all, and those company-set limits are routinely tighter than the federal securities laws. The policy document is public: since fiscal year 2024, public companies generally file it as Exhibit 19 to the annual report on Form 10-K. This post covers where the filing sits, what a company policy restricts beyond SEC rules, how those boundaries interact with 10b5-1 Trading Plans, and which planning decisions the window calendar actually governs.
Where Is a Company’s Insider Trading Policy Filed?
A public company’s insider trading policy is filed as Exhibit 19 to its annual report on Form 10-K and is retrievable through the SEC’s EDGAR database. Item 408(b) of Regulation S-K requires annual disclosure of whether the company has adopted insider trading policies and procedures governing the purchase, sale, and other dispositions of company securities by directors, officers, and employees. A company that has not adopted such policies must explain why not. Item 601(b)(19) of Regulation S-K requires the policy document itself to be filed, not merely described.
The requirement first applied to fiscal year 2024 Form 10-K filings, so calendar-year companies filed their first Exhibit 19 in early 2025.
One alternative compliance path exists. If all of a company’s insider trading policies are contained within a code of ethics already filed as Exhibit 14, the exhibit index may cross-reference Exhibit 14 rather than duplicate the text at Exhibit 19. A reader who finds no Exhibit 19 in a Form 10-K should check the exhibit index for that cross-reference before concluding the policy was not filed.
What Is Exhibit 19 of the Form 10-K?
Exhibit 19 is the designated exhibit slot where a public company files the full text of its insider trading policy alongside the annual report on Form 10-K. The SEC created it on December 14, 2022, in Release 33-11138, “Insider Trading Arrangements and Related Disclosures.” Before that release, insider trading policies circulated internally through compliance departments and employee handbooks, with no requirement that the document reach the public record.
The same rulemaking added Item 408(a) of Regulation S-K, which requires quarterly disclosure of the adoption or termination of 10b5-1 Trading Plans and non-Rule 10b5-1 trading arrangements by officers and directors. Exhibit 19 shows the rules of the road. Item 408(a) disclosure shows which officers and directors have adopted or ended a plan and when.
What Does an Insider Trading Policy Restrict That SEC Rules Do Not?
Company insider trading policies routinely restrict more than the federal securities laws do, and the additional restrictions fall into four common categories: pre-clearance requirements before any transaction, prohibitions on pledging company stock as loan collateral, prohibitions on hedging company stock, and blackout windows that open and close on dates the company sets rather than dates the SEC sets.
The federal baselines are narrower than most people assume. Rule 144 limits affiliate sales in any three-month period to the greater of 1% of outstanding shares or the average weekly trading volume over the prior 4 weeks. Section 16 requires reporting of covered transactions within 2 business days. Rule 10b5-1 imposes cooling-off periods before trading can begin under a plan. None of those rules tells a company it must stop there. A company can build a window schedule around earnings releases, require sign-off from a compliance officer, and extend every restriction to a longer period than the SEC requires.
Where the company rule and the SEC rule differ, the more restrictive of the two governs the transaction.
Does a Company Policy Override the SEC Cooling-Off Period for a 10b5-1 Trading Plan?
A company insider trading policy cannot shorten the SEC cooling-off period for a 10b5-1 Trading Plan, but it can lengthen it and can add conditions the SEC does not impose. Under the December 2022 amendments to Rule 10b5-1, directors and Section 16 officers must wait the later of 90 days after adoption or two business days after the issuer files the Form 10-Q or Form 10-K covering the fiscal quarter in which the plan was adopted, subject to a maximum of 120 days after adoption. All other persons other than the issuer wait 30 days after adoption.
The two-part test for directors and Section 16 officers means the adoption date alone does not determine when trading begins. A plan adopted early in a fiscal quarter can reach the 90-day mark before the quarterly report is filed, which pushes the start date out to two business days after that filing. A plan adopted late in the quarter typically clears the filing condition first, leaving 90 days as the operative constraint.
Common company additions include requiring plan adoption only during an open trading window, requiring pre-clearance of the plan by a compliance officer, limiting the number of plans an insider can maintain, and requiring the use of a designated broker. The structure and mechanics of these plans are covered in 10b5-1 Plans: A Structured Approach to Selling Company Stock.
How Do I Find Out If My Company Prohibits Hedging or Pledging Company Stock?
Two separate filings carry that information. Hedging policy is disclosed in the annual proxy statement under Item 407(i) of Regulation S-K, which requires the company to describe any policy on whether employees, officers, or directors are permitted to hedge or offset a decrease in the market value of company equity securities. The SEC adopted Item 407(i) in December 2018 under Section 955 of the Dodd-Frank Act, so proxy statements have carried this disclosure for several filing cycles.
Pledging restrictions typically appear in the text of the insider trading policy filed as Exhibit 19 rather than in the proxy statement. A policy that prohibits pledging generally addresses using company shares as collateral for margin loans and other borrowing arrangements. Reading both documents gives the full picture, because a company can permit one practice and prohibit the other.
The distinction determines which strategies remain available. A company hedging prohibition removes an Option Collar or a Prepaid Variable Forward from consideration entirely, regardless of whether those instruments are permissible under federal law. A pledging prohibition forecloses a securities-based line of credit collateralized by company shares. Rule 144 may permit an affiliate to sell a given number of shares in a quarter while a pre-clearance requirement independently blocks the trade. Additional approaches to accessing liquidity from concentrated stock sit inside these same boundaries.
Two people holding identical positions in two different issuers can face substantially different constraints on the same strategy. Interpretation of a specific policy provision belongs with the company’s legal and compliance function.
Which Planning Decisions Do Limited Trading Windows Control?
Limited trading windows directly control four planning decisions: cashflow timing, tax timing, portfolio rebalancing, and retirement timing.
Cash flow timing. Funding a property purchase, a tuition obligation, or a large one-time expense from company stock may require the sale to fall inside an open window. A transaction that closes during a blackout period gets funded from another source or gets moved.
Tax timing. Capital gains recognition, loss harvesting, and transfers of appreciated shares to a Donor-Advised Fund all land in the calendar year the window permits. A charitable transfer intended to offset a high-income year requires an open window before December 31, not after it.
Portfolio rebalancing. Target allocation drifts continuously as the share price moves and new grants vest. Correction may be limited to open windows, so drift can accumulate between them. The gap between the target allocation and the actual allocation is a function of the window calendar as much as the market. Coordinating that gap is the subject of concentrated stock planning.
Retirement timing. Trading eligibility at and after separation is set by the policy text, not by the departure date. The Exhibit 19 filing establishes how long restrictions extend past employment, which is why it belongs in the file before a retirement date is selected rather than after. Coordination across that transition is covered on the Executives in Transition page.
What Should Be Confirmed Before the Next Trading Window Opens?
Seven items are answerable in advance, and answering them before the window opens is what makes the window usable rather than reactive:
- What dollar amount of liquidity is required before the next window closes, including estimated tax payments and any scheduled obligations?
- What percentage of net worth sits in employer stock today, counting vested shares, unvested Restricted Stock Units, and in-the-money options separately?
- How many additional shares vest between the close of this window and the opening of the next one?
- Does the intended sale volume exceed the Rule 144 limit of the greater of 1% of outstanding shares or the average weekly trading volume over the prior 4 weeks?
- Has pre-clearance been requested, and how many business days does the compliance officer require to respond?
- Is a Form 4 filing required within 2 business days of the transaction, and who is responsible for filing it?
- If a 10b5-1 Trading Plan is under consideration, does the applicable cooling-off period extend past the date the proceeds are needed?
A window that opens on a question still unanswered is a window that closes on the same question.

Directors and Section 16 officers wait the later of 90 days after adoption or two business days after the issuer files the Form 10-Q or Form 10-K for the fiscal quarter of adoption, capped at 120 days. All other persons other than the issuer wait 30 days. Company policy can extend these periods.
Only if company policy permits hedging. Hedging policy is disclosed in the annual proxy statement under Item 407(i) of Regulation S-K, adopted in December 2018 under Section 955 of the Dodd-Frank Act. A hedging prohibition removes both instruments from consideration regardless of what federal securities law allows.
Only if the insider trading policy permits pledging. Pledging restrictions generally appear in the Exhibit 19 policy text rather than the proxy statement, and they address using company shares as collateral for margin loans and other borrowing. A company can permit hedging while prohibiting pledging, or the reverse.
The more restrictive of the two governs the transaction. A company can lengthen a cooling-off period, narrow a trading window, add pre-clearance, or prohibit conduct the SEC permits. A company cannot shorten a federal minimum or waive a federal reporting obligation.
Not necessarily. An open window is one condition among several. Pre-clearance from a compliance officer may still be required, Rule 144 caps affiliate sales at the greater of 1% of outstanding shares or average weekly volume over the prior 4 weeks in any three-month period, and Section 16 filers report covered transactions within 2 business days.
