Regulatory Notice 22-10

FINRA Reminds Member Firms of the Scope of FINRA Rule 3110 as it Pertains to the Potential Liability of Chief Compliance Officers for Failure to Discharge Designated Supervisory Responsibilities

Published Date:


Chief Compliance Officers (CCOs) at member firms play a vital role. For example, CCOs and their compliance teams help design and implement compliance programs, help educate and train firm personnel, and work in tandem with senior business management and legal departments to foster compliance with regulatory requirements. In this way, CCOs help promote strong compliance practices that protect investors and market integrity, as well as the member firm itself.1

Rule 3110 (Supervision) imposes specific supervisory obligations on member firms.2 The responsibility to meet these obligations rests with a firm’s business management, not its compliance officials. The CCO’s role, in and of itself, is advisory, not supervisory. Accordingly, FINRA will look first to a member firm’s senior business management and supervisors to determine responsibility for a failure to reasonably supervise. FINRA will not bring an action against a CCO under Rule 3110 for failure to supervise except when the firm conferred upon the CCO supervisory responsibilities and the CCO then failed to discharge those responsibilities in a reasonable manner.3 As a result, charges against CCOs for supervisory failures represent a small fraction of the enforcement actions involving supervision that FINRA brings each year.4

Background and Discussion


Rule 3110 sets out a comprehensive set of supervisory obligations for member firms and requires firms to designate individual supervisors and identify their responsibilities. The rule requires each member firm to establish and maintain a system, including written procedures, to supervise the activities of each associated person that is reasonably designed to achieve compliance with applicable securities laws and regulations, and with applicable FINRA rules.5 The rule also requires each member firm to designate an appropriately registered principal or principals with authority to carry out the supervisory responsibilities of the member for each type of broker-dealer business in which it engages, to designate one or more appropriately registered principals in branch offices with authority to carry out the supervisory responsibilities assigned to that office, and to assign each registered representative to an appropriately registered person who is responsible for supervising that representative’s activities.​​​​​​​6 Individual liability under Rule 3110 is predicated upon the firm’s express or implied designation of supervisory personnel and the delegation of supervisory responsibility to the designated individuals.​​​​​​​7 Individual supervisors have an additional duty under Rule 3110 to investigate “red flags” that suggest misconduct at the firm may be occurring and to act reasonably upon the results of the investigation.​​​​​​​8 FINRA can bring enforcement actions under Rule 3110 against individual supervisors when they fail to discharge reasonably their supervisory responsibilities.​​​​​​​9

A firm’s supervisory obligations under Rule 3110 rest with the firm and its president (or equivalent officer or individual, e.g., CEO) and flow down by delegation to the firm’s designated supervisors.10 The firm’s president (or equivalent officer or individual), not its CCO, “bears ultimate responsibility for compliance with all applicable requirements unless and until he [or she] reasonably delegates particular functions to another person in that firm, and neither knows nor has reason to know that such person’s performance is deficient.”11 Accordingly, the president (or equivalent officer or individual) and designated principals are responsible for fulfilling the firm’s supervisory obligations under Rule 3110.


A CCO’s role at a member firm, by contrast, is advisory, not supervisory. FINRA recognizes that compliance and supervision are separate, if related, functions. In Notice to Members 99-45, FINRA stated that “[i]t is important [to] recognize the distinction between written compliance guidelines and written supervisory procedures.”12 A CCO and the compliance team is, in the normal course, responsible for the former, not the latter. “Compliance guidelines generally set forth the applicable rules and policies that must be adhered to and describe specific practices that are prohibited.”13 By contrast, written supervisory procedures document the supervisory system to ensure that compliance guidelines are being followed.

To fulfill the compliance function, FINRA requires firms to designate one or more appropriately registered principals as a CCO.14 As set forth in FINRA Rule 3130, Supplementary Material .05, “A [CCO] is a primary advisor to the member on its overall compliance scheme and the particularized rules, policies and procedures that the member adopts.”15 Neither Rule 3110 nor Rule 3130, by themselves, attach supervisory responsibilities to a CCO.16

A CCO can and often does occupy another position at a firm, such as CEO.17 In such circumstances, CCOs likely would fall within the scope of Rule 3110 because of the supervisory authority designated to them based on another non-CCO position they hold within a firm’s business management. When an individual’s sole position at a firm is that of CCO, a more extensive assessment of liability under Rule 3110 may be needed, as outlined in the following section.



  1. Designation of Supervisory Responsibility

A CCO is not subject to liability under Rule 3110 because of the CCO’s title or because the CCO has a compliance function at a member firm. A CCO will be subject to liability under Rule 3110 only when—either through the firm’s written supervisory procedures or otherwise—the firm designates the CCO as having supervisory responsibility. This designation can occur in several ways. First, the member’s written procedures might assign to the CCO the responsibility to establish, maintain and update written supervisory procedures, both generally as well as in specific areas (e.g., electronic communications). Second, the written procedures might assign to the CCO responsibility for enforcing the member’s written supervisory procedures or other specific oversight duties usually reserved for line supervisors. Third, apart from the written procedures, a member firm, through its president or some other senior business manager, might also expressly or impliedly designate the CCO as having specific supervisory responsibilities on an ad hoc basis. Or the CCO may be asked to take on specific supervisory responsibilities as exigencies demand, such as the review of trading activity in customer accounts or oversight of associated persons. Only in circumstances when a firm has expressly or impliedly designated its CCO as having supervisory responsibility will FINRA bring an enforcement action against a CCO for supervisory deficiencies.

  1.  Applying the Reasonableness Standard

Even when a CCO has been designated as having supervisory responsibilities, FINRA will bring an action under Rule 3110 against the CCO only if the CCO has failed to discharge those responsibilities in a reasonable manner—as it would with any individual who has supervisory responsibility. Accordingly, once FINRA has found that the CCO has been designated by the firm as having supervisory responsibilities—including responsibility for establishing, maintaining and enforcing the firm’s written supervisory procedures that are reasonably designed to achieve compliance with applicable securities laws and regulations, and with applicable FINRA rules—the next question is whether the CCO reasonably discharged his or her designated supervisory responsibilities.

For example, if the CCO is responsible for establishing, maintaining and enforcing the firm’s written supervisory procedures, FINRA will ask whether the procedures were reasonably tailored to the firm’s business and whether they addressed the specific activities of the firm’s personnel. Whether a CCO’s performance of these responsibilities was reasonable depends upon the facts and circumstances of a particular situation. When assessing potential liability under Rule 3110, FINRA will evaluate whether the CCO’s conduct in performing designated supervisory responsibilities was reasonable in terms of achieving compliance with the federal securities laws, regulations, or FINRA rules.

  1. Factors For and Against Charging a CCO under Rule 3110

Not every violation of a FINRA rule results in a formal disciplinary action, so even when FINRA finds that a CCO failed to reasonably perform a designated supervisory responsibility, FINRA will consider whether charging the CCO under Rule 3110 in a formal disciplinary action is the appropriate regulatory response to address the violation. Factors that might weigh in favor of charging a CCO are the same factors that could apply to any individual who has supervisory responsibility under Rule 3110 and include, but are not limited to, the following: (1) the CCO was aware of multiple red flags or actual misconduct and failed to take steps to address them;18 (2) the CCO failed to establish, maintain, or enforce a firm’s written procedures as they related to the firm’s line of business;19 (3) the CCO’s supervisory failure resulted in violative conduct (e.g., a CCO who was designated with responsibility for conducting due diligence failed to do so reasonably on a private offering, resulting in the firm lacking a reasonable basis to recommend the offering to its customers);20 and (4) whether that violative conduct caused or created a high likelihood of customer harm.21

Factors that might weigh against charging the CCO include, but are not limited to, the following: (1) the CCO was given insufficient support in terms of staffing, budget, training, or otherwise to reasonably fulfill his or her designated supervisory responsibilities;22 (2) the CCO was unduly burdened in light of competing functions and responsibilities;23 (3) the CCO’s supervisory responsibilities, once designated, were poorly defined, or shared by others in a confusing or overlapping way;24 (4) the firm joined with a new company, adopted a new business line, or made new hires, such that it would be appropriate to allow the CCO a reasonable time to update the firm’s systems and procedures; and (5) the CCO attempted in good faith to reasonably discharge his or her designated supervisory responsibilities by, among other things, escalating to firm leadership when any of (1)–(4) were occurring.25

In addition to the above factors, FINRA also will consider whether it is more appropriate to charge the firm or its president with failure to reasonably supervise rather than the CCO. Likewise, FINRA will consider whether it is more appropriate to charge another individual at the firm, such as an executive manager or a business line supervisor, who had more direct responsibility for the supervisory task at issue, or who was more directly involved in the supervisory deficiency. Finally, FINRA also will consider whether, based on the facts and circumstances of a particular case, it is more appropriate to bring informal, as opposed to formal, action against the CCO for failure to supervise. In some cases, it may be more appropriate to issue a Cautionary Action Letter, particularly in cases involving a CCO’s first-time violation of Rule 3110.

2 This Notice is limited to FINRA Rule 3110. It does not address other supervisory requirements under federal securities laws. Cf. SEC, Division of Trading and Markets, Frequently Asked Questions about Liability of Compliance and Legal Personnel at Broker-Dealers under Sections 15(b)(4) and 15(b)(6) of the Exchange Act, Sept. 30, 2013; Compliance Programs of Investment Companies and Investment Advisers, Release Nos. IA-2204, IC-26299, 2003 SEC LEXIS 2980, at n.73 (Dec. 17, 2003) (discussing when a CCO might be subject to Section 203(e)(6) of the Investment Advisers Act of 1940).

3 This Notice focuses on CCOs and does not encompass anti-money laundering compliance personnel. See FINRA Rule 3310(d); Rule 3310, Supplementary Material .02 (Review of Anti-Money Laundering Compliance Person Information). It also does not address enforcement actions against CCOs for misconduct unrelated to designated supervisory responsibilities, such as providing false documents to FINRA or failing to timely update their Uniform Application for Securities Industry Registration or Transfer (Form U4). See, e.g., Merrimac Corporate Securities, Inc., Exchange Act Release No. 86404, 2019 SEC LEXIS 1771, at *9 (July 17, 2019); Allen Holeman, Exchange Act Release No. 86523, 2019 SEC LEXIS 1903, at *16-17 (July 31, 2019).

4 For example, from 2018–2021, of the nearly 440 FINRA enforcement actions involving violations of Rule 3110 for supervisory failures, CCOs were charged in only 28 instances. And in only 10 of these matters did FINRA charge a CCO who was not also the chief executive officer (CEO) or president of the firm. For each of these 10 matters, FINRA found that the firm had conferred upon the CCO specific supervisory responsibilities which the CCO failed reasonably to perform, in violation of Rule 3110.

5 See Rules 3110(a) and (b). Rule 3110 applies to persons associated with a member firm as much as it applies to a member firm. See FINRA Rule 0140(a) (“Persons associated with a member shall have the same duties and obligations as a member under the Rules.”). Thus, FINRA may bring an action against an associated person, including a CCO, when FINRA finds the individual has violated Rule 3110.

6 See Rules 3110(a)(2), (4) and (5). Rule 3110(b)(6)(A) requires a firm’s written supervisory procedures to include “the titles, registration status, and locations of the required supervisory personnel and the responsibilities of each supervisory person.”

7 Importantly, to bring a case under Rule 3110, FINRA does not have to establish an underlying violation of the federal securities laws or other FINRA rules. Dep’t of Enforcement v. Lek Securities Corp., No. 2009020941801, 2016 FINRA Discip. LEXIS 63, at *35-36 (NAC Oct. 11, 2016).

Many chief compliance officers are already registered as principals. NASD Regulation does not presume that these individuals have supervisory responsibility by virtue of their title.
