Public Company Disclosure: Periodic Reports, Regulation FD, and Insider Trading Liability

Document type: Article Practice area: Business and Corporate — Securities Jurisdiction: United States (federal) Last reviewed: 5 September 2026

Most securities enforcement matters do not begin with a lie. They begin with a Tuesday.

An analyst calls the head of investor relations and asks how the quarter is tracking. A director mentions a pending acquisition at a dinner. A CFO signs a certification without reading the disclosure controls memorandum. A vice president exercises options the week before an earnings release because the option was expiring. None of these people set out to commit fraud. All of them created exposure.

The disclosure system exists to prevent those Tuesdays, and it works by turning judgment calls into procedures. A company with functioning disclosure controls has already decided who may speak to investors, what triggers an 8-K, when the trading window closes, and who reviews a certification before it is signed. A company without them decides each question in the moment, under time pressure, usually by whoever happens to be in the room.

The reporting architecture

Public reporting obligations arise under Section 13(a) or Section 15(d) of the Securities Exchange Act. Section 13 requires issuers with registered securities to file the reports the Commission prescribes.

The periodic reports:

Form 10-K. The annual report. Business description, risk factors, management's discussion and analysis, audited financial statements, controls disclosures, executive compensation (frequently incorporated from the proxy statement), and a substantial set of exhibits. The content requirements come principally from Regulation S-K and Regulation S-X.

Form 10-Q. The quarterly report. Unaudited financials, MD&A, updated risk factors, and disclosure of legal proceedings and other developments.

Form 8-K. The current report, due for enumerated events on a short deadline — generally four business days.

Proxy statement. Filed under Section 14 and Regulation 14A, containing the disclosure required for the matters submitted to shareholders, including executive compensation.

Section 16 reports. Forms 3, 4, and 5, filed by directors, officers, and ten percent holders under Section 16(a).

Beneficial ownership reports. Schedules 13D and 13G, filed by holders crossing five percent under Section 13(d).

The Sarbanes-Oxley certifications. Section 302 requires the principal executive and financial officers to certify, in each periodic report, that they have reviewed it, that it contains no untrue statement or material omission, that the financial statements fairly present the issuer's condition, and that they are responsible for and have evaluated disclosure controls and internal control over financial reporting. Section 906 adds a separate certification with criminal penalties. Section 404 requires management's assessment of internal control over financial reporting and, for accelerated filers, an auditor attestation.

Materiality

Everything in this area turns on materiality, and the standard is deceptively simple.

TSC Industries, Inc. v. Northway, Inc., 426 U.S. 438 (1976) supplies the formulation: a fact is material if there is a substantial likelihood that a reasonable shareholder would consider it important in deciding how to vote — or, adapted to trading contexts, in making an investment decision. More precisely, there must be "a substantial likelihood that the disclosure of the omitted fact would have been viewed by the reasonable investor as having significantly altered the 'total mix' of information made available."

Basic Inc. v. Levinson, 485 U.S. 224 (1988) adopted TSC's standard for Rule 10b-5 and addressed contingent events — there, merger negotiations. The Court rejected a bright-line rule that preliminary negotiations are immaterial as a matter of law, holding instead that materiality depends on a balancing of the probability that the event will occur and the anticipated magnitude of the event in light of the totality of company activity. Basic also adopted the fraud-on-the-market presumption of reliance, which is what makes securities class actions viable.

Matrixx Initiatives, Inc. v. Siracusano, 563 U.S. 27 (2011) rejected a bright-line statistical significance test for adverse event reports about a pharmaceutical product, holding that materiality cannot be reduced to a single quantitative metric and that context matters.

What this means in practice. There is no percentage threshold that makes a fact immaterial. A quantitatively small item can be material if it masks a trend, changes compliance with a covenant, affects a segment the market watches, involves management integrity, or was singled out in prior disclosure. Companies that use a five percent screen and stop have adopted a rule the Commission has repeatedly said does not exist.

Opinions and beliefs. Omnicare, Inc. v. Laborers District Council Construction Industry Pension Fund, 575 U.S. 175 (2015) addressed statements of opinion in a registration statement. A sincere opinion is not an untrue statement of fact merely because it turns out to be wrong. But an opinion statement can mislead by omission if it omits material facts about the issuer's inquiry into, or knowledge concerning, the opinion — where those facts conflict with what a reasonable investor would take the statement to convey. The practical lesson: "we believe we are in compliance" carries an implicit representation about the basis for the belief.

Pure omissions. Macquarie Infrastructure Corp. v. Moab Partners, L.P., 601 U.S. 257 (2024)** held that a failure to disclose information required by Item 303 of Regulation S-K — the MD&A known-trends requirement — does not by itself support a private claim under Rule 10b-5(b). Rule 10b-5(b) reaches half-truths, not pure omissions; liability requires a statement rendered misleading by the omission. The decision matters: it channels pure-omission theories into Commission enforcement and Section 11 claims rather than private 10b-5 actions.

Form 8-K: the current report

The 8-K items impose short deadlines on events the market is entitled to learn promptly. The principal categories:

Business and operations. Entry into or termination of a material definitive agreement; bankruptcy or receivership; mine safety.

Financial information. Completion of an acquisition or disposition; results of operations and financial condition; creation of a direct financial obligation or an obligation under an off-balance-sheet arrangement; triggering events accelerating an obligation; costs associated with exit or disposal activities; material impairments.

Securities and trading markets. Delisting or transfer of listing; unregistered sales of equity securities; material modification to rights of security holders.

Accountants and financial statements. Changes in the registrant's certifying accountant; non-reliance on previously issued financial statements — the "Item 4.02" filing that announces a restatement.

Corporate governance and management. Changes in control; departure or election of directors and principal officers; amendments to the articles or bylaws; changes in fiscal year; amendments to the code of ethics or waivers.

Regulation FD disclosure. The item used to make a public disclosure that satisfies Regulation FD.

Other events. The catch-all, used at the registrant's option for anything it deems material.

Cybersecurity. Material cybersecurity incidents, with disclosure required within four business days of determining materiality — a determination that must itself be made without unreasonable delay.

The recurring practical problems:

Determining the trigger date. The four business days run from the triggering event, and for several items the event is a determination — of materiality, of non-reliance, of an impairment. The determination must be made promptly; a company cannot extend the deadline by delaying the determination.

The "material definitive agreement" question. Item 1.01 is triggered by an agreement material to the registrant that is not made in the ordinary course. Both halves are judgment calls, and companies frequently under-file.

Item 4.02 non-reliance. The filing announcing that previously issued financials should no longer be relied upon is among the most consequential a company makes, and it is often prepared under extreme time pressure by people who have just discovered a problem. The determination of non-reliance is made by the board or the audit committee, and it starts the clock.

Regulation FD

Regulation FD addresses selective disclosure. Its rule is short: when an issuer, or a person acting on its behalf, discloses material non-public information to specified categories of persons — broker-dealers, investment advisers, investment companies, and holders of the issuer's securities where it is reasonably foreseeable they will trade — the issuer must make public disclosure of that information.

Timing. For an intentional disclosure, the public disclosure must be simultaneous. For a non-intentional disclosure, it must be made promptly — within twenty-four hours or before the commencement of the next day's trading on the New York Stock Exchange, whichever is later.

"Public disclosure" means filing or furnishing a Form 8-K, or disseminating through another method reasonably designed to provide broad, non-exclusionary distribution. A press release over a wire service qualifies. A posting on a company website or social media account can qualify where the company has taken steps to alert the market that it uses that channel.

Who is covered. Senior officials — directors, executive officers, investor relations personnel, public relations personnel — and any employee who regularly communicates with the covered categories.

What is excluded:

Communications with a person who owes the issuer a duty of trust or confidence, such as an attorney, investment banker, or accountant.
Communications with a person who expressly agrees to maintain the information in confidence.
Disclosures in connection with most registered securities offerings.
Communications with the press, rating agencies, and ordinary-course business counterparties who are not within the covered categories.

Enforcement. Regulation FD does not create a private right of action, and a violation is not itself a Rule 10b-5 violation. The Commission enforces it through cease-and-desist proceedings and civil penalties, and it has done so in cases involving private guidance to analysts, selective confirmation of consensus estimates, and one-on-one meetings in which a company official signaled a direction the market had not been given.

The practical controls that prevent violations:

A designated spokespersons policy. A short list of people authorized to speak with analysts and investors, and a rule that everyone else refers inquiries to them.
Prepared materials, reviewed in advance. Scripts, Q&A, and a pre-cleared set of talking points for every investor meeting.
A no-comment discipline on questions outside disclosed information. "We do not comment on that" is always available and never a violation.
Caution about confirming or correcting estimates. Telling an analyst her number is "a little high" is guidance, and it is the classic violation.
The quiet period. A self-imposed period before earnings during which the company does not meet with investors.
Prompt remediation. If something slips, the company has until the next morning's opening to file an 8-K. The remediation is far cheaper than the violation, and companies that hesitate lose the option.

Rule 10b-5 and the private action

Section 10(b) and Rule 10b-5 prohibit, in connection with the purchase or sale of any security, employing a device to defraud, making an untrue statement of material fact or omitting a material fact necessary to make statements not misleading, or engaging in a practice that operates as a fraud.

The elements of a private claim:

A material misrepresentation or omission;
Scienter — intent to deceive, manipulate, or defraud, satisfied in most circuits by recklessness;
A connection with the purchase or sale of a security;
Reliance;
Economic loss; and
Loss causation — that the misrepresentation caused the loss, not merely that the price later fell.

Reliance and the fraud-on-the-market presumption. Basic permits a class-wide presumption of reliance where the security traded in an efficient market and the misrepresentation was public and material. Without it, individual reliance questions would defeat class certification.

What can be litigated at certification. Amgen Inc. v. Connecticut Retirement Plans & Trust Funds, 568 U.S. 455 (2013) held that materiality need not be proved at the certification stage — it is a common question that will be resolved for all class members alike. Halliburton Co. v. Erica P. John Fund, Inc. preserved the Basic presumption but held that a defendant may rebut it at certification with evidence of a lack of price impact. Price impact litigation, with competing event-study experts, is now the principal battleground at certification.

The PSLRA. The Private Securities Litigation Reform Act imposes heightened pleading: the complaint must specify each statement alleged to be misleading and the reasons why, and must state with particularity facts giving rise to a strong inference of scienter. Discovery is stayed during a motion to dismiss. The Act also created a safe harbor for forward-looking statements accompanied by meaningful cautionary language identifying important factors that could cause actual results to differ, or where the plaintiff cannot prove the statement was made with actual knowledge of its falsity.

The safe harbor's practical requirements. Boilerplate does not work. The cautionary language must be meaningful and tailored: it must identify the important factors that could cause actual results to differ from those projected. Risk factors that have not been updated in three years, or that warn of risks that have already materialized, do not satisfy it.

Control person liability. Section 20(a) imposes liability on persons who control a violator, subject to a good faith defense. It reaches officers and directors who did not themselves make a statement.

Insider trading

There is no statute defining insider trading. The law is judicial construction built on Section 10(b) and Rule 10b-5, and it is organized around duty.

Chiarella v. United States, 445 U.S. 222 (1980) established that Rule 10b-5 does not impose a general duty to disclose or abstain on anyone possessing material non-public information. Chiarella, a printer who deduced target names from documents, owed no duty to the shareholders of the companies whose stock he bought. A duty is required, and it arises from a relationship of trust and confidence.

The classical theory. A corporate insider — officer, director, employee — who trades in the company's securities on material non-public information breaches a duty to the shareholders with whom he trades. Temporary insiders, such as lawyers, bankers, and accountants who receive confidential information for corporate purposes, assume the same duty.

Dirks v. SEC, 463 U.S. 646 (1983) addressed tippees. A tippee inherits the insider's duty only if the insider breached a duty by disclosing, and the tippee knew or should have known of the breach. Whether the insider breached turns on whether he personally benefited, directly or indirectly, from the disclosure. Dirks himself was not liable: the insider who gave him information about a massive fraud did so to expose it, not for personal gain.

Salman v. United States, 580 U.S. 39 (2016) confirmed that the personal benefit element is satisfied where an insider makes a gift of confidential information to a trading relative or friend. No pecuniary benefit is required; the gift is the benefit, because the tipper has effectively traded and given the proceeds away.

United States v. O'Hagan, 521 U.S. 642 (1997) adopted the misappropriation theory: a person who trades on material non-public information in breach of a duty owed to the source of the information violates Rule 10b-5, even though he owes no duty to the persons with whom he trades. O'Hagan was a lawyer at a firm representing an acquirer; he owed a duty to his firm and its client, and trading in the target's stock breached it. The Court also upheld Rule 14e-3, which prohibits trading on material non-public information about a tender offer without regard to any duty.

Rule 10b5-1 codifies the "awareness" standard: a person trades "on the basis of" material non-public information if he was aware of it when he traded. Use is presumed from awareness.

Rule 10b5-2 identifies non-exclusive circumstances in which a duty of trust or confidence exists for misappropriation purposes: an agreement to maintain confidence; a history, pattern, or practice of sharing confidences; and receipt from a spouse, parent, child, or sibling, subject to a defense that no reasonable expectation of confidentiality existed.

Rule 10b5-1 plans

Rule 10b5-1(c) provides an affirmative defense for trades made under a plan adopted when the person was not aware of material non-public information.

The requirements:

The plan must be adopted in good faith and not as part of a scheme to evade.
The person must have acted in good faith with respect to the plan — not merely at adoption, but throughout.
The plan must specify the amount, price, and date of trades; provide a written formula or algorithm for determining them; or delegate discretion to a person who is not aware of material non-public information.
Cooling-off periods apply: for directors and officers, the later of ninety days after adoption or two business days after the filing of the periodic report for the fiscal quarter in which the plan was adopted, subject to a maximum of 120 days; for other persons, thirty days.
Directors and officers must certify at adoption that they are not aware of material non-public information and are adopting the plan in good faith.
No overlapping plans for open-market trades, subject to limited exceptions.
Single-trade plans are limited to one in any twelve-month period.
Quarterly disclosure of adoption, modification, and termination of plans by directors and officers, with the material terms.
Annual disclosure of insider trading policies and procedures, filed as an exhibit.

Why modifications matter. A modification of the amount, price, or timing of trades terminates the existing plan and constitutes the adoption of a new one, restarting the cooling-off period. Frequent modifications undermine the good faith element and have featured in enforcement actions.

Practical guidance:

Adopt plans only during an open window, with a certification and a legal review.
Set a firm cooling-off period in the company's own policy, at or above the rule's minimum.
Prohibit overlapping plans and single-trade plans by policy.
Require legal approval for any modification or termination.
Track and disclose plan activity as the rules require — the disclosure obligation is on the company, and it depends on insiders telling the company what they have done.

Section 16

Section 16 applies to directors, officers, and beneficial owners of more than ten percent of a registered class.

Reporting. Form 3 on becoming subject; Form 4 within two business days of most transactions; Form 5 annually for exempt transactions not previously reported.

Short-swing profits. Section 16(b) requires disgorgement to the issuer of any profit realized from a purchase and sale, or sale and purchase, within any period of less than six months. It is a strict liability provision: intent is irrelevant, possession of inside information is irrelevant, and the matching is done to produce the maximum recoverable profit, pairing the lowest purchase against the highest sale within any six-month window.

Who enforces it. The issuer, or — far more often — a shareholder suing derivatively, with counsel who monitors Section 16 filings for matchable transactions.

Practical controls: pre-clearance of every insider transaction; a six-month lookback and lookforward check before approving any trade; and attention to non-obvious transactions — option exercises, gifts, transfers to trusts, tax withholding elections, and deferred compensation elections can all be reportable, and some are matchable.

Disclosure controls and procedures

The certifications under Sarbanes-Oxley Section 302 require the certifying officers to state that they are responsible for establishing and maintaining disclosure controls and procedures, that they have designed them to ensure material information is made known to them, and that they have evaluated their effectiveness as of the end of the period.

What a functioning system looks like:

A disclosure committee. Typically the general counsel, the chief financial officer, the controller, the head of internal audit, the chief accounting officer, the head of investor relations, and representatives of the significant business units. It meets before each periodic filing, reviews the draft, and considers whether anything material has occurred that the draft does not capture.

A sub-certification process. Business unit and functional leaders sign a questionnaire and a certification covering their areas: material contracts entered or terminated, litigation and regulatory contacts, accounting judgments and estimates, related-party transactions, control deficiencies, and anything they believe should be disclosed. These flow up to the certifying officers, and they are what makes the top-level certification supportable.

An 8-K trigger protocol. A written list of the events that require an 8-K, distributed to the people who would first learn of each, with a named contact and a rule to call immediately rather than assessing materiality themselves.

A materiality assessment process. Documented, with the participants and the reasoning, for every close question. The document is the evidence that the judgment was made carefully.

Escalation paths that work. Someone in a plant who learns of an environmental incident must know who to call. The 8-K deadline runs from the event, not from when legal hears about it.

Documentation. Committee minutes, sub-certifications, the materiality assessments, and the record of what was considered and rejected. These are what make the certification honest and what a regulator will ask for.

Enforcement and consequences

Commission remedies. Cease-and-desist orders; civil penalties; disgorgement; officer-and-director bars; and in insider trading cases, civil penalties of up to three times the profit gained or loss avoided under Section 21A.

Criminal exposure. Willful violations are criminal. The Section 906 certification carries its own criminal penalties for knowing false certification.

Private litigation. Class actions under Rule 10b-5, subject to the PSLRA; Section 11 and 12 claims for registration statement misstatements; Section 14(a) claims for proxy misstatements; and Section 18 claims for reliance on false statements in filed reports under Section 18.

Derivative litigation. Breach of fiduciary duty claims against directors and officers arising from the same facts, and oversight claims where the failure is systemic.

Practical consequences beyond liability. A restatement triggers an Item 4.02 filing, an internal investigation, an auditor reassessment, potential covenant defaults, D&O insurance notice obligations, and — frequently — a stock drop that generates the class action. The legal exposure is often the smaller part.

Attorney reporting obligations. Sarbanes-Oxley Section 307 requires attorneys appearing and practicing before the Commission to report evidence of a material violation up the ladder — to the chief legal officer, and if the response is inadequate, to the audit committee or the board. In-house and outside securities counsel should know the standard and the procedure before they need them.

And Section 304 permits recovery from the CEO and CFO of bonuses and incentive compensation received during the twelve months following a filing that is later restated due to misconduct — even where the officer was not personally responsible for the misconduct.

A worked scenario

Kesterhaven Semiconductor (NASDAQ: KSTR) manufactures power management chips. On a Thursday in the second month of its third quarter, its largest customer — 23 percent of revenue — tells Kesterhaven's VP of sales, informally, that it is qualifying a second source and expects to shift roughly 40 percent of its volume beginning next year.

The VP mentions it to the CFO on Friday. Here is what happens next in a company with a functioning program, and in one without.

The company with controls

Friday afternoon. The CFO calls the general counsel. The general counsel convenes an ad hoc materiality assessment: the CFO, the controller, the VP of sales, and outside counsel.

The questions asked, and documented:

What exactly was said, by whom, and how firm is it? An informal statement by a purchasing manager, not a written notice, and no volumes or dates confirmed.
Is there a contract? A supply agreement with rolling forecasts, no minimum volumes.
What is the quantified impact if it happens as described? Approximately 9 percent of annual revenue, beginning in roughly fourteen months.
Has the company said anything about customer concentration? Yes — a risk factor, and MD&A commentary on the customer's growth.
Is this a known trend or uncertainty that MD&A must address?
Does it trigger an 8-K item? Not Item 1.01 or 1.02 — no agreement entered or terminated. Consider Item 8.01.

The conclusion. The information is material under the Basic probability-magnitude balance — the magnitude is large even though the probability is not yet certain. But there is no 8-K item requiring disclosure of an informal customer statement, and the company is not obligated to disclose merely because information is material. What the company cannot do is trade, tip, or speak selectively.

The actions taken, that same day:

The trading window closes immediately for the individuals aware of the information, by memorandum from the general counsel. The list is short and specific.
A note goes to investor relations: no meetings, no calls, and if asked about customer concentration, refer to the disclosed risk factor and say nothing more.
A hold notice issues covering the customer relationship.
The materiality assessment is documented in a memorandum, with the participants, the facts, and the reasoning.
The disclosure committee is convened for the following week to consider whether MD&A in the coming 10-Q must address it as a known trend, and whether the risk factors need updating.
The audit committee chair is briefed.

What happens in the 10-Q. The company adds MD&A disclosure: it has been advised by a significant customer of an intention to qualify a second source, the customer represented 23 percent of revenue in the period, and a reduction in volumes from this customer could materially affect results. The risk factor is updated from generic concentration language to specific.

What happens with insiders. Two officers had 10b5-1 plans adopted five months earlier, during an open window, with the required certifications. Those plans continue to execute, and that is the correct outcome — the affirmative defense is available precisely because the plans were adopted when the officers were not aware of this information, and stopping them would itself be a discretionary act inconsistent with the plan.

A third officer had asked, two weeks earlier, to adopt a new plan. That request is denied until the information is public or stale.

Outcome. No violation, no enforcement, and a documented record. When the customer's shift is announced publicly nine months later and the stock declines, the class action complaint that follows encounters a company that disclosed the trend when it learned of it, updated its risk factors, and can produce the contemporaneous assessment.

The company without controls

Friday. The CFO thinks about it over the weekend.

Monday. He mentions it to the CEO. They agree it is preliminary and decide to wait.

Tuesday. The head of investor relations, unaware, holds a scheduled call with an analyst and, asked about customer concentration, says the relationship is "as strong as ever." A Regulation FD problem and a potential 10b-5 problem in one sentence — not because the statement was selectively disclosed, but because it was false and it was made to an analyst who published on it.

Thursday. A vice president in operations who attended a meeting where the second-source qualification was discussed exercises expiring options and sells. He is not on any restricted list because there is no restricted list.

Six weeks later. The 10-Q is filed with no MD&A discussion of the trend and the same generic risk factor.

Nine months later. The customer's shift becomes public. The stock declines 31 percent.

What follows: a class action alleging the "as strong as ever" statement and the 10-Q omissions; a Commission inquiry that begins with the trading records and finds the vice president's sale; a Regulation FD analysis of the analyst call; a Section 302 certification the CFO must explain; and an internal investigation conducted by counsel the audit committee retains, because the CFO's conduct is now among the subjects.

The difference between the two companies was not integrity. It was a Friday afternoon phone call and a documented process for making one decision.

Duties to correct and to update

Two related doctrines sit behind many of the hardest disclosure judgments.

The duty to correct applies where a statement was false when made — because of a mistake, not a change in circumstances — and the issuer later discovers it. The obligation to correct promptly is widely recognized, and it does not depend on any specific line-item requirement.

The duty to update applies where a statement was true when made but has become materially misleading because of subsequent events. Courts have divided on its existence and scope. The narrower view recognizes a duty only where the original statement was forward-looking, of continuing effect, and the kind of statement on which investors reasonably continue to rely — a stated intention to complete a transaction, for example, or an affirmed guidance range.

Practical guidance regardless of the doctrinal uncertainty:

A statement that is currently false is a problem whether or not a court would recognize a duty to update, because continued silence while investors trade on it is the fact pattern from which scienter is inferred.
Guidance is the classic case. A company that has affirmed a range and knows it will miss badly faces a real question. The safest course is to update publicly; the most common failure is to wait for the scheduled release.
Website and social media content are statements. A page that says a product is in development, a customer is a partner, or a facility is operating remains a statement while it is up. Companies rarely audit their own websites against current facts, and plaintiffs do.
Avoid creating the obligation. Statements framed as of a date — "as of the date of this report" — with meaningful cautionary language and an express disclaimer of any obligation to update are the standard protection, and they work better than a general disclaimer buried in a footer.

Frequently asked questions

Is there a percentage below which something is immaterial? No. The Commission has rejected exclusive reliance on quantitative thresholds. A small item can be material where it masks a trend, affects covenant compliance, concerns a closely watched segment, involves management integrity, or was the subject of prior disclosure.

Do we have to disclose material information as soon as we have it? Not generally. There is no free-standing duty to disclose all material information. Disclosure obligations arise from a specific requirement — an 8-K item, a periodic report line item, Regulation FD after a selective disclosure — or from a duty to correct or update a prior statement that has become misleading. What you may not do while in possession of material non-public information is trade, tip, or speak selectively.

Can we tell a large shareholder before we announce? Only if that shareholder expressly agrees to keep it confidential, or otherwise owes a duty of confidence. Otherwise it is a Regulation FD violation requiring simultaneous public disclosure.

An analyst's model is wrong. Can we tell her? Confirming or correcting an estimate is guidance and is the classic FD violation. If you want to correct the market, do it publicly.

We disclosed something by accident. What now? File a Form 8-K, or otherwise disseminate broadly, by the later of twenty-four hours or the opening of the next trading day. Move immediately; the window is short and the remediation is far cheaper than the violation.

Can an insider trade during a blackout under a 10b5-1 plan? Yes, and that is the point of the plan — provided it was properly adopted when the person was not aware of material non-public information, the cooling-off period ran, the certification was made, and the person continues to act in good faith with respect to the plan.

Should we stop an existing plan when material information arises? Generally no. Stopping a plan is a discretionary act that can undermine the defense for the plan's other trades and can itself look like trading on information. Get advice before acting; the answer is usually to let it run.

Is a gift of stock reportable? Yes, on Form 4 for Section 16 insiders, and gifts have their own timing considerations. Non-obvious transactions — option exercises, transfers to trusts, tax withholding, deferred compensation elections — are frequently reportable and sometimes matchable for short-swing purposes.

Does Regulation FD apply to conversations with the press? The press is not within the covered categories, so a disclosure to a journalist is not itself an FD violation. But it may be material information reaching the market unevenly, and it can create other problems. Treat it as a disclosure event.

What is the most common failure? Nobody calls the general counsel on Friday. The disclosure system is only as good as the escalation paths, and those depend on ordinary employees knowing that a customer conversation, a plant incident, or an auditor's question is something to report immediately.

What to remember

Materiality has no threshold. TSC and Basic supply a qualitative standard, and Matrixx rejected reducing it to a metric. A five percent screen is not the law.

Contingent events are assessed by probability times magnitude. A deal that may not happen can be material long before it is certain.

Opinions carry an implicit representation about their basis. Omnicare means "we believe we are in compliance" is a statement about the inquiry behind the belief.

Pure omissions are not private 10b-5 claims. Macquarie requires a statement rendered misleading; the Commission and Section 11 remain available.

Regulation FD is about channels, not intent. Designated spokespersons, prepared materials, and a no-comment discipline prevent nearly every violation, and the twenty-four-hour remediation window forgives the rest if you act.

Insider trading is about duty. Chiarella requires one; Dirks and Salman supply the tippee framework and confirm a gift is a benefit; O'Hagan reaches those who owe a duty to the source.

Rule 10b5-1 is a defense with conditions. Cooling-off periods, certifications, no overlapping plans, single-trade limits, quarterly disclosure, and good faith throughout — not merely at adoption.

Section 16(b) is strict liability. Six months, maximum-profit matching, no intent element, and non-obvious transactions count.

The safe harbor requires meaningful, tailored cautionary language. Stale risk factors do not qualify.

And the controls are the substance. A disclosure committee, sub-certifications, an 8-K trigger protocol, documented materiality assessments, and escalation paths that work are what turn a Tuesday into a process instead of an enforcement matter.
