Regulation Best Interest (SEA Rule 15l-1)
Quick Answer
Regulation Best Interest (SEA Rule 15l-1) requires broker-dealers to act in a retail customer's best interest at the time of a recommendation, without placing firm or personal interest ahead of the customer's. The general obligation is satisfied only when all four component obligations are met: Disclosure, Care, Conflict of Interest, and Compliance. Reg BI applies only to retail customers.
Regulation Best Interest (Reg BI), codified at SEA Rule 15l-1, raises the standard of conduct a broker-dealer (BD) and its associated persons (APs) owe a retail customer at the time of a recommendation. For Series 6 purposes, Reg BI is the rule that absorbs and goes beyond FINRA Rule 2111 suitability for retail recommendations.
What is the general Regulation Best Interest standard?
A broker-dealer (and its associated persons) must:
- Act in the best interest of the retail customer at the time the recommendation is made
- Not place the financial or other interest of the BD (or the AP) ahead of the retail customer's interest
Retail customer means a natural person (or the non-professional legal representative of a natural person) who receives a recommendation of a securities transaction or investment strategy and uses it primarily for personal, family, or household purposes.
Exam Tip: Gotchas
- Reg BI applies only to retail customers - natural persons (or their non-professional legal reps) using the recommendation primarily for personal, family, or household purposes. Recommendations to institutions (corporate pension plan, bank treasury desk, hedge fund) are outside Reg BI and governed by FINRA Rule 2111.
What are the four component obligations of Regulation Best Interest?
Reg BI's "general obligation" is satisfied only when all four component obligations are met. Compliance with some but not others is not a safe harbor.
| Obligation | What It Requires |
|---|---|
| Disclosure Obligation | Provide the retail customer with full and fair written disclosure before or at the time of the recommendation, covering the scope and terms of the relationship, material fees and costs, and material conflicts of interest. Must identify that the firm (and AP) is acting as a broker-dealer. |
| Care Obligation | Exercise reasonable diligence, care, and skill to understand the product (reasonable-basis), have a reasonable basis to believe the recommendation is in the retail customer's best interest based on their investment profile (customer-specific), and have a reasonable basis to believe a series of recommendations is not excessive and is in the customer's best interest (quantitative). |
| Conflict of Interest Obligation | Establish, maintain, and enforce written policies and procedures reasonably designed to identify conflicts and (at minimum) disclose or eliminate them. Mitigate conflicts that create incentives for the AP to place firm interest ahead of customer interest. Identify and eliminate sales contests, quotas, bonuses, and non-cash compensation tied to sales of specific securities (or types of securities) within a limited period of time. |
| Compliance Obligation | Establish, maintain, and enforce written policies and procedures reasonably designed to achieve overall compliance with Reg BI. |
Think of it this way: Disclosure is "tell the customer up front." Care is "do the work to know the product and the customer, and make a reasoned recommendation." Conflict of Interest is "identify the things that could tempt you, and handle each one at the right level: disclose, mitigate, or eliminate." Compliance is "write it all down and supervise it." The customer's best-interest protection is the combination of all four.
How does the Reg BI Care Obligation relate to FINRA Rule 2111?
For retail customers, the Reg BI Care Obligation parallels and exceeds FINRA Rule 2111 suitability.
- The three components of the Care Obligation mirror the three obligations of Rule 2111 (reasonable-basis, customer-specific, quantitative)
- But the standard is best interest, not merely suitable
- A recommendation that meets the Reg BI Care Obligation necessarily satisfies Rule 2111
Exam Tip: Gotchas
- Reg BI applies "at the time the recommendation is made." It is not a continuous fiduciary duty like the Advisers Act standard. A rep does not owe an ongoing monitoring duty under Reg BI unless the firm's agreement separately imposes one. (The Investment Advisers Act of 1940 imposes a continuous fiduciary duty on investment advisers; that is a different regime.)
How must conflicts of interest be handled under Regulation Best Interest?
The Conflict of Interest Obligation requires three different responses depending on the conflict.
| Conflict Type | Required Response |
|---|---|
| Material conflicts of interest (general) | Disclose at minimum, or eliminate |
| Conflicts that create incentives for the AP to place firm interest ahead of customer interest | Mitigate (policies and procedures to reduce the incentive) |
| Sales contests, quotas, bonuses, non-cash compensation tied to sales of specific securities (or types of securities) within a limited period of time | Eliminate - disclosure is not a cure |
Think of it this way: Reg BI treats conflicts on a sliding scale. Soft conflicts get disclosure. Moderate conflicts get mitigation. The one category that the SEC treats as incurable is the short-timeframe sales contest tied to specific products. That one must be eliminated outright.
Exam Tip: Gotchas
- Sales contests and non-cash compensation based on sales of specific securities (or types of securities) within a limited period of time must be ELIMINATED. Disclosure is not a cure for this category of conflict. A Series 6 question that asks which conflict must be eliminated (not just disclosed) is testing this rule.
How do Reg BI, FINRA Rule 2111, and KYC differ?
| Standard | Applies To | Trigger | Key Focus |
|---|---|---|---|
| FINRA Rule 2090 (KYC) | All accounts | Opening and maintaining the account | Essential facts and authority of persons acting for the customer |
| FINRA Rule 2111 (Suitability) | Any customer | A recommendation is made | Suitable recommendation under the 2111(a) profile |
| Reg BI (SEA 15l-1) | Retail customers only | A recommendation is made | Best interest at the time of recommendation; four component obligations |
What are the most tested Regulation Best Interest concepts?
Exam Tip: Gotchas
- Reg BI is retail only. Institutional recommendations stay under FINRA 2111.
- Four component obligations (Disclosure, Care, Conflict of Interest, Compliance) - all four required.
- Sales contests on specific securities must be ELIMINATED, not just disclosed.
- "At the time the recommendation is made" - Reg BI is not a continuous fiduciary duty.
- Care Obligation mirrors Rule 2111's three components but applies a best-interest (not merely suitable) standard.
