FINRA Rule 9900

FINRA Rule 9900 sits at the very end of the 9000 Code of Procedure, positioned immediately after FINRA Rule 9870 — the final rule of the Rule 9800 Temporary and Permanent Cease and Desist Orders series — and containing only FINRA Rule 9910 as its sole child rule. FINRA Rule 9910 was adopted through SR-FINRA-2018-037, filed with the SEC for immediate effectiveness on October 24, 2018 and noticed in the Federal Register on November 7, 2018.

The Unique Character of the Rule 9900 Series

Every other major division within the 9000 Code of Procedure governs proceedings, rights, and obligations applicable to FINRA's regulated population — members, associated persons, and other persons subject to FINRA's jurisdiction. The Rule 9200 series governs disciplinary proceedings against members. The Rule 9500 series governs eligibility, expedited, and exemption proceedings affecting members and associated persons. The Rule 9800 series governs cease and desist orders against members and associated persons.

The Rule 9900 series is categorically different. It is the only division of the Code of Procedure that governs FINRA's own personnel — current and former officers and employees of FINRA itself — rather than the members and associated persons FINRA regulates. 

This represents an institutional self-governance function within the Code of Procedure: FINRA, in its capacity as a self-regulatory organization wielding the substantial enforcement and adjudicative powers documented throughout the rest of the 9000 series, has placed restrictions on its own personnel's post-employment conduct directly within the same Code that governs its regulatory authority over the industry.

The placement of these restrictions within the Code of Procedure — rather than in FINRA's separate corporate governance documents, employee handbooks, or By-Laws — is itself significant. It signals that these restrictions are part of the same body of procedural law that governs FINRA's adjudicative integrity. A former FINRA Hearing Officer, NAC staff member, or enforcement attorney who later appears before FINRA on behalf of a member or respondent in a Rule 9200 or Rule 9800 series proceeding implicates the same separation-of-functions and impartiality concerns that pervade the rest of the Code — and FINRA Rule 9910 addresses precisely this category of concern.

The Policy Foundation: The Revolving Door Problem

FINRA Rule 9900's single child rule addresses what is commonly known in administrative and regulatory law as the revolving door problem — the concern that personnel who move between a regulatory body and the regulated industry may exploit relationships, institutional knowledge, and nonpublic information gained during their regulatory tenure for the benefit of their subsequent private employers, or may use the prospect of lucrative post-regulatory employment to influence their conduct while still serving in their regulatory capacity.

The revolving door problem is a recognized concern across the entire regulatory landscape — federal agencies, state regulators, and self-regulatory organizations alike have adopted post-employment restrictions addressing the same underlying concerns. For FINRA specifically, the concern is especially acute given FINRA's unique position: FINRA personnel have access to confidential examination findings, ongoing investigation details, enforcement strategy, and the deliberations of Hearing Panels and the NAC — information whose value to a member firm or a respondent's counsel could be substantial if improperly shared or leveraged after the FINRA employee's departure to private practice or industry employment.

SR-FINRA-2011-032 — Implement Revolving Door Restrictions on Former Officers of FINRA — confirmed from the search results as a 2011 filing, represented an earlier iteration of FINRA's institutional efforts to address this concern, predating the more comprehensive FINRA Rule 9910 framework adopted in 2018.

FINRA Rule 9910: The Single Substantive Rule

FINRA Rule 9910 — Post-Employment Conflict of Interest Restrictions; Nonpublic Information — is the sole substantive rule within the Rule 9900 series. Adopted through SR-FINRA-2018-037 with immediate effectiveness on October 24, 2018, the rule establishes four distinct categories of restrictions confirmed from the Federal Register filing.

The first restriction prohibits any former officer from making certain communications to or appearances before FINRA for one year following the end of their FINRA employment. This one-year cooling-off period applies to former officers specifically — reflecting the heightened concern about officers, who by virtue of their seniority typically had broader access to FINRA's strategic decision-making, institutional relationships, and confidential information than rank-and-file employees.

The second restriction prohibits any former employee — not limited to officers — from making certain communications to or appearances before FINRA at any time, without temporal limitation, in a particular matter involving specific parties in which the employee was personally and substantially involved during their FINRA employment. This permanent, matter-specific restriction reflects the principle that a former employee's direct personal involvement in a specific matter creates a conflict of interest that does not diminish with time — if a FINRA examiner personally investigated a specific member firm's conduct, that examiner should never represent or assist that same firm in connection with that same matter, regardless of how much time has passed.

The third restriction prohibits any former employee from making certain communications to or appearances before FINRA for two years in a particular matter involving specific parties that was under the employee's official responsibility during the last year of their FINRA employment. This two-year restriction addresses a broader category than personal and substantial involvement — official responsibility encompasses matters that fell within an employee's supervisory or oversight purview even if the employee was not personally and substantially involved in the day-to-day handling of that specific matter. The two-year limitation, rather than the permanent restriction applicable to matters of personal and substantial involvement, reflects a calibrated judgment that supervisory responsibility — while creating a real conflict concern — is less individually compromising than direct personal involvement and therefore warrants a time-limited rather than permanent restriction.

The fourth restriction applies to current employees rather than former employees — prohibiting any current employee from disseminating or disclosing nonpublic information for a purpose unnecessary to the performance of their FINRA duties. This restriction is the nonpublic information component referenced in FINRA Rule 9910's title, and it operates prospectively on current personnel rather than retrospectively on departed personnel — addressing the risk that a current employee, anticipating future private-sector employment, might disclose nonpublic information to a prospective future employer or other outside party before their FINRA employment even ends.

The Structural Parallel to Federal Revolving Door Restrictions

FINRA Rule 9910's four-category structure closely parallels the post-employment restrictions applicable to federal government employees under 18 U.S.C. § 207 — the federal conflict of interest statute governing communications and representations by former federal officers and employees. The one-year restriction for former officers, the permanent restriction for matters of personal and substantial involvement, and the time-limited restriction for matters of official responsibility all mirror the structure of the federal statute's analogous categories.

This structural parallel is not coincidental — FINRA, as a self-regulatory organization exercising delegated authority under the Exchange Act and subject to SEC oversight, has long looked to federal ethics and conflict of interest standards as a model for its own institutional integrity rules. By adopting a framework that mirrors 18 U.S.C. § 207's categories, FINRA Rule 9910 imports decades of federal regulatory and judicial interpretation regarding what constitutes personal and substantial involvement, official responsibility, and a particular matter involving specific parties — interpretive guidance that informs how FINRA Rule 9910's parallel categories should be understood and applied.

The 2018 Adoption Context

FINRA Rule 9910's adoption in October 2018 — filed for immediate effectiveness under Section 19(b)(1) of the Exchange Act and SEA Rule 19b-4 — reflects FINRA's institutional maturation as a self-regulatory organization with an increasingly sophisticated and substantial enforcement apparatus. By 2018, FINRA's Department of Enforcement, Office of Hearing Officers, and National Adjudicatory Council represented a substantial professional adjudicative infrastructure whose personnel possessed exactly the kind of institutional knowledge, confidential information access, and professional relationships that revolving door restrictions are designed to address. The immediate effectiveness filing — rather than a notice-and-comment rulemaking with a delayed effective date — reflects FINRA's characterization of FINRA Rule 9910 as an internal governance and ethics rule rather than a rule directly imposing new substantive obligations on FINRA's regulated population, a characterization that under SEA Rule 19b-4(f) permits immediate effectiveness for certain categories of rule changes.

Connection to FINRA's Separation of Functions Framework

FINRA Rule 9900 and its sole child rule FINRA Rule 9910 connect conceptually to FINRA Rule 9144's separation of functions requirement — the provision discussed throughout this dictionary's Rule 9100 series entries that prohibits persons who participate in adjudicative functions from also participating in investigative or prosecutorial functions in the same matter. Both FINRA Rule 9144 and FINRA Rule 9910 serve the same underlying institutional integrity purpose — ensuring that the persons who exercise FINRA's regulatory and adjudicative authority do so without conflicts of interest that could compromise the fairness and perceived fairness of FINRA's proceedings. FINRA Rule 9144 addresses conflicts arising from a single person's simultaneous roles within a current proceeding; FINRA Rule 9910 addresses conflicts arising from a person's transition between FINRA employment and the private sector, before or after that transition occurs.

Examination Relevance and Key Takeaways

FINRA Rule 9900 is tested on the Series 7 and Series 24 examinations as the series-level marker for FINRA's institutional self-governance framework — the smallest and most distinctive division of the Code of Procedure, containing a single rule that governs FINRA's own personnel rather than FINRA's regulated population.

The key points to retain are these: FINRA Rule 9900 is the series-level marker for a single-rule series containing only FINRA Rule 9910 — it has no operative text and no amendment history of its own; the Rule 9900 series is the only division of the Code of Procedure governing FINRA's own current and former officers and employees rather than members, associated persons, or other regulated persons; FINRA Rule 9910 — Post-Employment Conflict of Interest Restrictions; Nonpublic Information — was adopted through SR-FINRA-2018-037 with immediate effectiveness on October 24, 2018; FINRA Rule 9910 establishes four restriction categories — a one-year communications and appearances restriction for former officers, a permanent restriction for matters of personal and substantial involvement by former employees, a two-year restriction for matters under a former employee's official responsibility during their last year of employment, and a current-employee prohibition on disseminating nonpublic information for purposes unnecessary to FINRA duties; the four-category structure closely parallels the federal post-employment conflict of interest framework under 18 U.S.C. § 207; and FINRA Rule 9900 sits at the very end of the 9000 Code of Procedure, positioned immediately after FINRA Rule 9870 with FINRA Rule 9910 as its sole child rule.
