Regulation Best Interest (Reg BI) - SEC Rule 15l-1

With the foundation of compensation types and fairness standards in place, Reg BI represents the overarching standard that governs how broker-dealers must act when making recommendations to retail customers.


Overview and Applicability

  • Reg BI applies to broker-dealers and their associated persons when making a recommendation to a retail customer
  • A retail customer is a natural person (or their legal representative) using the recommendation for personal, family, or household purposes
  • Reg BI requires that broker-dealers act in the best interest of the retail customer at the time a recommendation is made, without placing the financial or other interest of the broker-dealer ahead of the customer's interest
  • Reg BI is satisfied only if the broker-dealer complies with four component obligations

Exam Tip: Gotchas

Reg BI applies only to broker-dealers and their associated persons. It does not apply to investment advisers, who are held to a fiduciary standard under the Investment Advisers Act. Do not confuse the two standards on the exam.


The Four Component Obligations

ObligationKey Requirements
DisclosureBefore or at the time of recommendation, disclose in writing: the capacity in which the BD is acting; all material fees, costs, and charges; the type and scope of services; all material facts relating to conflicts of interest
CareExercise reasonable diligence, care, and skill; understand the potential risks, rewards, and costs of the recommendation; have a reasonable basis to believe the recommendation is in the customer's best interest; consider reasonably available alternatives
Conflict of InterestEstablish and maintain written policies to identify, disclose, and mitigate (or eliminate) conflicts; eliminate sales contests, sales quotas, bonuses, and non-cash compensation based on the sale of specific securities or types of securities within a limited period
ComplianceEstablish, maintain, and enforce written policies and procedures reasonably designed to achieve compliance with Reg BI as a whole

Compensation Disclosure Under Reg BI

The Disclosure Obligation has specific requirements related to compensation:

  • Disclose all material fees and costs relating to the customer's transactions, holdings, and accounts
  • Disclose the sources and types of direct and indirect compensation the broker-dealer receives
  • The specific dollar amount of compensation need not be disclosed, but disclosure must be full and fair and may require disclosing the general magnitude of compensation
  • Disclose conflicts arising from proprietary products, third-party payments, and compensation arrangements

Conflict of Interest Obligation - Compensation Rules

The Conflict of Interest Obligation targets specific compensation practices:

  • Broker-dealers must eliminate (not just disclose or mitigate):
    • Sales contests
    • Sales quotas
    • Bonuses tied to the sale of specific securities
    • Non-cash compensation based on selling specific securities or types of securities within a limited period

Think of it this way: Most conflicts under Reg BI can be addressed through disclosure and mitigation. But sales contests and quotas must be eliminated entirely.


NASAA Incorporation of Reg BI

  • NASAA's Statement of Policy on Dishonest or Unethical Business Practices (as amended 2022) incorporates Reg BI at the state level
  • Section 1.d specifically states that it is a dishonest practice to fail to comply with Regulation Best Interest obligations when making recommendations to retail customers
  • This means Reg BI compliance is enforceable as a state law obligation in jurisdictions that have adopted the NASAA statement
  • Violations can trigger both federal SEC enforcement and state administrator action

Exam Tip: Gotchas

  • Reg BI applies to broker-dealers only. Investment advisers have a separate fiduciary standard.
  • Sales contests must be eliminated, not just disclosed or mitigated.
  • NASAA has adopted Reg BI, making it testable as both a federal and state requirement.
