Rule 10b5-1 trading plans, explained for filing readers

A Rule 10b5-1 plan is a written arrangement in which a company insider sets out in advance what will be traded, when and in what quantity, and then lets the trades happen without further input. Done properly it gives the insider an affirmative defence if they are later accused of trading on material nonpublic information.

The reasoning is that the decision was made when the person did not hold that information, so the trade is not evidence that they did. The SEC tightened the conditions for that defence in December 2022, and those amendments became effective on 27 February 2023.

For anyone reading filings, the practical part is short. Forms 4 and 5 now carry a checkbox showing whether a transaction was made under a plan intended to satisfy Rule 10b5-1(c), with the plan's adoption date in the explanation. Section 16 filers have used the amended forms since 1 April 2023.

What the plan actually is

Rule 10b5-1 sits under Rule 10b-5, the SEC's general anti fraud rule. The affirmative defence is available where the person can show that, before becoming aware of material nonpublic information, they had entered into a binding contract to trade, instructed someone else to trade for their account, or adopted a written plan.

The arrangement then has to do one of three things. It can specify the amount, price and date of each trade. It can set out a written formula, algorithm or computer program that determines them. Or it can leave the person unable to exercise any subsequent influence over how, when or whether trades happen.

The rule also treats tinkering as starting again. Any modification or change to the amount, price or timing of the trades is treated as terminating the plan and adopting a new one, which restarts the cooling off clock.

Why executives use them

Company insiders spend much of the year unable to trade. Blackout periods close ahead of results, and material nonpublic information can land at any time. An executive whose wealth sits mostly in one company's shares, with tax on vesting equity to pay, has a narrow set of open windows.

A plan solves that timing problem by moving the decision to a moment the person can defend. It also solves an appearance problem, since a sale scheduled eight months earlier reads differently from one placed the week before a bad announcement.

Plans are used for buying too, though far less often. Most insider buying you come across in filings is discretionary.

What the SEC changed in 2022

The Commission adopted the amendments on 14 December 2022 in a release titled Insider Trading Arrangements and Related Disclosures.

The cooling off periods

For directors and officers, no trades can occur under a new or modified plan until the later of ninety days after adoption, or two business days following disclosure of the issuer's financial results for the quarter in which the plan was adopted, capped at 120 days after adoption.

For persons other than the issuer and its directors and officers, the cooling off period is thirty days after adoption. Issuers have no equivalent period under the rule.

Certification and good faith

Directors and officers now have to include a representation in the plan certifying that, on the date of adoption, they are not aware of any material nonpublic information about the security or the issuer, and that they are adopting the plan in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5.

The good faith requirement runs wider than that certification: the defence is available only where the person has acted in good faith with respect to the plan, covering how it operates, not just how it was signed.

Limits on multiple and single trade plans

Persons other than issuers generally cannot rely on the defence while running overlapping plans for open market trades. The carve outs are narrow: sequenced plans where the later one does not begin trading until the earlier is finished, and one eligible sell to cover arrangement for tax withholding on vesting equity. Single trade plans are limited to one in any twelve month period.

The disclosure side

The same release added disclosure requirements aimed at making plan use visible rather than inferred.

Item 408 of Regulation S-K requires quarterly disclosure of the adoption, modification or termination of Rule 10b5-1 plans and certain other trading arrangements by directors and officers, along with the material terms other than price. Companies must also describe their insider trading policies annually, and Item 402(x) covers the timing of option awards granted close to the release of material nonpublic information.

On the Section 16 side, Forms 4 and 5 gained the plan checkbox from 1 April 2023. Issuers other than smaller reporting companies had to apply the new disclosures in periodic reports covering the first full fiscal period beginning on or after 1 April 2023, with smaller reporting companies six months later. The release also moved bona fide gifts of securities onto Form 4, on the same two business day timetable as other transactions, rather than the annual Form 5.

How to spot a plan trade on a filing

Start with the checkbox near the top of the form. It is the only definitive marker, telling you the filer intended the transaction to satisfy Rule 10b5-1(c).

Then read the footnotes. The adoption date belongs in the explanation of responses, and it is often the most useful figure on the page, because it tells you when the decision was taken. A sale reported in November under a plan adopted in March is a March decision wearing a November date.

Older filings need different handling. Before the amended forms took effect in April 2023 there was no checkbox, so a plan trade was flagged only if the filer noted it in a footnote. The absence of a marker on a 2019 filing is not evidence that no plan existed.

Regular sales of similar size on similar dates each quarter usually indicate a plan even where the paperwork is sparse. And a plan trade is not automatically uninteresting, since plans get adopted, modified and terminated, and quarterly Item 408 disclosure makes those events visible. A newly adopted plan is itself a decision.

How InsiderPulse handles this

InsiderPulse reads SEC Form 4 filings as one input to the score it gives each asset it covers, alongside congressional trade disclosures, options activity, dark pool and volume data, prices and news. Transaction codes and filing details are part of what it surfaces, so a scheduled sale is not presented as the same event as a discretionary purchase. Ask Pulsey, the built in assistant, answers questions about a specific filing with its sources cited. The score organises data rather than offering a view on any company, and coverage is US listed stocks and ETFs plus crypto, forex and commodities, not ASX shares.

InsiderPulse is a data tool. Nothing on this page is financial advice.
