Investment Banker Liability in Securities Cases.

Last Updated on: 4th August 2026, 01:33 am

While a broad term, “investment banker” is a colloquialism rather than a precise legal term. Firms and individuals involved in investment banking can act in various legal capacities, including investment bank, broker-dealer, investment adviser, underwriter, and investment banker, and each of these roles can carry its own distinct securities-law liabilities. Investment bankers can face liability as individuals, in addition to the liability that may arise for their firms.

Investment banks, underwriters, and broker-dealers can face securities investigations and civil claims from the SEC, state authorities, the DOJ, and private plaintiffs, and they can face proceedings in FINRA, CFTC, and NFA forums as well. Individual investment bankers can also face liability; and they can face this liability in the same proceedings as their firms or in proceedings that target them exclusively.

In many cases, however, FINRA is the primary source of exposure for investment banks, broker-dealers, and the individuals who work for them. FINRA can issue demands during member-firm examinations; and it can open investigations and pursue disciplinary enforcement action in its own administrative proceeding. When FINRA’s disciplinary proceedings lead to fines and other sanctions, they are subject to review by the U.S. Securities and Exchange Commission (SEC) and, thereafter, by the federal courts of appeals, by a person aggrieved by a final Commission order; and arbitration proceedings involving customer claims are governed by FINRA’s arbitration rules and are subject to the Federal Arbitration Act.

The SEC, DOJ, and state authorities can initiate investigations, and they can pursue civil litigation, civil enforcement action, and (in appropriate cases) criminal prosecutions based on their investigative findings. The CFTC and NFA have their own investigative and enforcement powers and proceedings for conduct involving commodities, including commodities-related securities, derivatives, and swaps.

Accounting irregularities can trigger investigations, class action litigation, and derivative litigation, often involving complex issues like fair value accounting and good-will impairment. Offering unregistered securities can prompt investigations and enforcement litigation in the U.S. District Court with jurisdiction.

Which Securities Claims Can Reach Banks and Individual Bankers?

Securities fraud claims based on material misstatements or omissions commonly fall under one of four sections: the Securities Act of 1933’s Section 11, Section 12(a)(2), the Securities Exchange Act of 1934’s Rule 10b-5, and the Exchange Act’s Section 20(a). While these are the main avenues, others exist, and the particular claim(s) that present(s) an individual’s or entity’s liability risk will depend on the specific transaction involved, the party’s role, and the facts alleged (or proven).

Each of these statutes and rules carries its own set of requirements, exceptions, and implications for liability. As an example, under the Securities Act’s Section 11, liability applies to material misstatements or omissions in a registration statement. Section 12(a)(2) applies to statutory “sellers” that offer securities based on the material defects in a prospectus or oral communications. Rule 10b-5 claims require materiality, scienter, reliance, economic loss, and loss causation. Rule 10b-5(b) primary liability, in particular, generally attaches to the person or entity with ultimate authority over a statement, including its content and whether and how to communicate it.

The Securities Act and Exchange Act also both contain provisions regarding “control-person liability” that can impose liability on issuers, broker-dealers, investment advisers, investment banks, parent companies, other control persons, and even individual employees. The Securities Act’s Section 15 governs control-person liability for underlying Section 11 and Section 12 violations, while the Exchange Act’s Section 20(a) governs control-person liability for a controlled person’s underlying violation of any provision of the Exchange Act or its rules.

Regarding “aiding and abetting” securities fraud, private plaintiffs cannot bring a standalone Rule 10b-5 aiding-and-abetting claim, but the Securities and Exchange Commission (SEC) can bring enforcement actions based on Exchange Act Section 20(e). In addition, the Dodd-Frank Act expanded the SEC’s aiding-and-abetting authority: Sections 929M and 929N extended aiding-and-abetting liability to the Securities Act of 1933, the Investment Company Act of 1940, and the Investment Advisers Act of 1940, and Section 929O lowered the required state of mind under Exchange Act Section 20(e) so that recklessly, not only knowingly, providing substantial assistance is sufficient.

While these claims have potential applicability in the context of investment banking, this represents far from the full breadth of claims that could potentially reach investment banks, underwriters, and individual investment bankers. As a result, when facing a securities investigation, defense counsel must carefully assess both the merits of the specific charges asserted and the risk that additional claims will be added. A strategic response requires not only a deep understanding of the applicable statutes and rules, but an awareness of their implications in practice and the evolving nature of federal enforcement in the securities area.

When Is an Investment Bank Liable as an Underwriter?

Under Section 2(a)(11) of the Securities Act, underwriters are persons who have “purchased from an issuer with a view to, or offer[] or sell[] for an issuer in connection with, the distribution of any security, or participate[] or ha[ve] a direct or indirect participation in any such undertaking,” but the term “shall not include a person whose interest is limited to a commission from an underwriter or dealer not in excess of the usual and customary distributors’ or sellers’ commission.” As a result, underwriter status can be established based on participation in securities distributions, and, unlike statutory “sellers,” underwriters’ status does not necessarily depend on the number of securities sold or the specific manner in which the offering was conducted. With this in mind, purchasing securities from an issuer for subsequent distribution can be sufficient to establish underwriter status in appropriate circumstances.

A key aspect of the definition of “underwriter” under the Securities Act is the absence of a per se broker-dealer qualification. The SEC and courts have consistently held that broker-dealer registration alone is not sufficient to establish status as an underwriter under the Securities Act, and broker-dealers must either fulfill the statutory definition of “underwriter” in their specific transaction or (in the context of a particular offering) enter into an underwriting agreement with the issuer.

Section 11 (15 U.S.C. § 77k) imposes liability for material misstatements and omissions in registration statements on: (i) issuers; (ii) signing officers and directors, (iii) named experts, and, (iv) underwriters (among others). However, this Section 11 liability is subject to a comprehensive “due-diligence defense” that protects defendants who: (i) conduct “reasonable investigation,” and (ii) have “reasonable grounds to believe” that there is no material misstatement or omission.

The scope of Section 11’s due-diligence defense does not extend to issuers. While issuers can face liability under both Section 11 and Section 12(a)(2) for material misstatements and omissions in prospectuses, they can generally avoid liability under Section 12(a)(2) by establishing their reasonable efforts to ensure that the material misstatement or omission is absent.

Nonissuer Section 11 defendants generally must establish their due diligence, meaning that they must show both (i) that they conducted a reasonable investigation, and (ii) that they had reasonable grounds to believe that the material misstatement or omission was not present.

Section 11 also permits reliance on portions of registration statements that have been certified (or “expertised”) by a named expert, provided that the defendant had no reasonable grounds to believe that the expert’s certification was unfounded.

To reach liability for individual experts (or their firms) under Section 11, the registration statement must specifically identify the portion (or portions) for which the expert is to be liable, and the expert must have consented to the certification of this material portion.

When Can Advice with Respect to Mergers and Going-Private Transactions Give Rise to Fiduciary-Duty or Disclosure Liability?

With respect to mergers and other going-private transactions, M&A advice can give rise to both fiduciary-duty and disclosure claims. Bankers advising target boards in these transactions may owe fiduciary duties directly to boards and to boards’ shareholders; and bankers can also face “aiding and abetting” liability (for example, in Delaware) for knowingly assisting boards with breaches of fiduciary duty. While M&A deals can give rise to securities-law disclosure claims as well, such liability exposure typically results from bankers’ failure to properly disclosures key information in a proxy statement or other stockholder disclosures.

As for fiduciary-duty claims, the extent of a banker’s fiduciary obligations will depend on the nature of the relationship, any pertinent undertaking or representation the banker makes, any governing contractual provisions, the applicable state law, and the specific role the banker plays in the transaction.

In Delaware, where M&A cases frequently end up litigated, aiding-and-abetting liability for investment banks and other advisers is a substantial risk. In Delaware, a party is potentially liable for “aiding and abetting” a breach of fiduciary duty by a corporate director if (i) a fiduciary relationship existed; (ii) the fiduciary breached that duty; (iii) the defendant knowingly participated in the breach, meaning it had actual knowledge of the breach and rendered substantial assistance; and (iv) the breach proximately caused damages.

In addition to its substantive rules, FINRA also promulgates rules that impose detailed disclosures and procedural obligations for the preparation of “fairness opinions” in certain types of transactions. For example, Rule 5150 (“Fairness Opinions”) imposes multiple substantive and procedural requirements for “covered fairness opinions” regarding mergers and acquisitions.

With respect to disclosure liability, the primary issue (in most cases) will be whether the banker (or banker’s firm) has failed to make a “material” disclosure in its fairness opinion or other advising materials.

In other words, information is generally deemed “material” if its disclosure would have “significantly altered the total mix of information” available to reasonable investors. While the material omissions rule under Rule 10b-5 generally does not apply to pure omissions (absent an affirmatively misleading statement), the Rule still requires disclosure in appropriate circumstances (i.e., where the omission renders a statement materially misleading).

What Happens When Civil and Criminal Proceedings Run Together?

The SEC and DOJ can, and often do, conduct simultaneous investigations, and a civil securities proceeding and a criminal prosecution can run parallel to each other as well. While this frequently occurs, this presents a unique set of challenges for defense strategy.

The most pertinent differences arise with respect to (i) the burden of proof, (ii) the impact of invoking the Fifth Amendment, and (iii) whether the civil proceeding should be stayed.

In fact, the burden of proof is the same for most SEC enforcement proceedings as for most private securities litigation, i.e., the plaintiff or the SEC must prove it’s more likely than not that the defendant violated the relevant statute or rule. On the other hand, most criminal prosecutors must prove their cases beyond a reasonable doubt. This is obviously a significant difference, and it presents various strategic implications in appropriate circumstances.

In a criminal case, invoking the Fifth Amendment protects a defendant against self-incrimination. But in a civil proceeding, invoking the Fifth Amendment can lead the trier of fact to draw an “adverse inference” against the party invoking the privilege.

While judges will sometimes stay civil proceedings in light of parallel criminal proceedings, this is far from an automatic entitlement. In fact, most civil judges do not consider a parallel criminal proceeding to constitute “good cause” for a stay.

In today’s digital age, organizations must ensure the preservation of relevant documents, e-mails, text messages, and hard drive data. When litigation (or a government investigation) becomes reasonably anticipated, organizations are required to place a litigation hold on all potentially relevant information.

Generally speaking, an organization’s outside counsel represents the organization. It does not automatically represent the individual employees or executives with whom it interacts. With this in mind, organization’s counsel must issue so-called “Upjohn Warnings” during internal interviews; which explain, among other things, that (i) the attorney represents the company and not the employee, and (ii) the company, not the employee, controls the privilege with respect to any information shared during the interview.

While voluntary disclosure of some information can avoid the need for a document production, voluntary government disclosure will waive the attorney-client privilege and the work-product protection, both for (i) communications between company lawyers and company employees and, (ii) documents prepared in anticipation of litigation.

What Penalties and Financial Protections Are At Stake?

In addition to the administrative and civil penalties discussed above, the SEC may seek: (i) disgorgement of profits made from, and/or payment of losses incurred by, those investors who were affected by the alleged fraud; (ii) other monetary sanctions; and (iii) various industry-related restrictions.

Under the Securities Act’s Section 12(a)(2), the available remedy is either rescission of the transaction (i.e., the return of the purchaser’s investment) or, in appropriate cases (i.e., in appropriate circumstances), monetary damages. Section 11 allows plaintiffs to assert liability claims and seek remedies against an issuer’s registration statement underwriters and other intermediaries on a joint and several liability basis. Section 11(f) permits defendants to seek contribution among themselves.

The SEC generally considers indemnification for the liability under the Securities Act contrary to public policy. However, indemnification arrangements are generally permitted under the Exchange Act.

Section 21(d) of the Exchange Act authorizes injunctions, civil penalties, and temporary and permanent bars on serving as officer or director of any issuer subject to the federal securities laws.

The Exchange Act imposes various criminal penalties, including fines and imprisonment of up to twenty years, for violations of the Exchange Act that were willful.

The Scope of Indemnification and Coverage

With respect to indemnification and coverage, investment banks and broker-dealers usually require their officers and employees to indemnify them against any liability that may arise in connection with the employees’ performance of their job duties.

Under the Delaware General Corporation Law §145, corporations, other than foreign corporations, have the power to indemnify their officers and directors, and their agents, employees, and employees of subsidiaries. Delaware’s indemnification statute also permits the advance of legal fees to these persons and persons subject to claims arising by reason of their status as directors, officers, or agents. However, as in the case of indemnification, the power to advance legal fees requires a qualifying repayment undertaking.

In order to obtain D&O insurance coverage, the policy must specifically name the D&O professional as an insured. Importantly, coverage is not automatically extended to agents or contractors working on behalf of the insurance company’s insured.

In today’s litigious era, insurers also specifically exclude coverage for various forms of professional and executive liability. D&O insurance policies generally exclude coverage for “insured vs. insured” claims, claims seeking exemplary, punitive, or criminal damages, and claims for an insured’s deliberate or dishonest conduct. D&O insurance policies also contain various “allocation provisions” that limit coverage for claims which are not exclusively related to the policyholder’s duties.

When Does Liability Exposure Truly End After Closure?

Generally speaking, there is rarely a single “closure date” from which liability terminates. The length of time that can pass before the window of liability closes depends on the specific statute(s) and rule(s) involved.

For example, Section 13 of the Securities Act imposes a general one-year limitations period, which starts to run in the event of “material misstatements or omissions in registration statements; material misstatements or omissions in the distribution of securities; and material misstatements or omissions in disclosure documents.” This Section 13 limitations period is also subject to a three-year “repose period,” which also begins to run on the date of the violation.

On the other hand, many other types of securities fraud claims (including claims under Section 12(a)(2) of the Securities Act and Rule 10b-5 of the Exchange Act) have limitation periods and repose periods imposed by the federal statute of limitations codified at 28 U.S.C. §1658(b). Under this statute, the applicable limitation period is two years, and the applicable repose period is five years (i.e., with respect to the date of the violation).

When will a securities investigation (or other securities proceeding) provide absolute finality for any securities-law liability?

There is no single “closure” event; and there are no guaranteed results. There are various possible outcomes, all with different implications:

• SEC staff closing letters require no judicial ruling to determine their validity.
• Agency declinations (i.e., the SEC or DOJ’s decision to not seek charges or initiate enforcement litigation) do not adjudicate the case on its merits; as such, declinations (i) do not establish whether a securities violation has occurred, (ii) do not create binding precedent for a subsequent proceeding, and, (iii) do not bar other agencies (or private plaintiffs) from pursuing corresponding charges or enforcement action.
• Dismissal of a civil securities litigation case with prejudice generally bars subsequent litigation; whereas dismissal of a civil securities litigation case without prejudice generally (i) does not bar refiling with the same (or a different) plaintiff, and (ii) does not otherwise affect plaintiff’s ability to amend the complaint and refile to avoid similar grounds for dismissal.
• A settlement Agreement does not establish liability for the parties involved, unless (i) the terms of the Agreement expressly establish a party’s liability, or (ii) the Agreement is executed in connection with a judgment that establishes a party’s liability.
• An arbitration award (i) gives effect to an arbitrator’s finding that has been either certified or approved by a court, and, (ii) can be challenged in a court, which can then confirm, modify, or vacate the arbitration award.
• When a securities investigation ends without charges or enforcement action, it ends without charges or enforcement action.
