Best Interest Obligations and Suitability Requirements

With an understanding of how firms communicate with the public, you can now examine the standards that govern what firms actually recommend. This is the most complex and frequently tested topic in this unit.


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

Regulation Best Interest establishes the standard of conduct for broker-dealers when making recommendations to retail customers.

Core requirement: The broker-dealer must act in the customer's best interest at the time of the recommendation.

The Four Component Obligations

Reg BI is satisfied by complying with four component obligations:

ObligationWhat It Requires
1. DisclosureProvide the customer with Form CRS and make full and fair disclosure of all material facts, including conflicts of interest
2. CareExercise reasonable diligence, care, and skill in making the recommendation
3. Conflict of InterestEstablish written policies to identify, disclose, and mitigate or eliminate conflicts of interest
4. ComplianceEstablish written policies and procedures to achieve compliance with Reg BI

Exam Tip: Gotchas

  • Reg BI has four obligations, not just "act in the best interest." The exam tests all four: Disclosure, Care, Conflict of Interest, and Compliance. Knowing the standard exists is not enough; know what each obligation requires.

Form CRS (Customer Relationship Summary)

Form CRS (SEC Rule 17a-14) is a brief, plain-language summary that helps retail investors understand the firm:

  • Length: 2-4 pages
  • Content: Services offered, fees and costs, conflicts of interest, disciplinary history, and how to get more information
  • Delivery: Must be provided at the beginning of the relationship or before/at the time of a recommendation

Exam Tip: Gotchas

  • Form CRS is only 2-4 pages. It is a brief summary, not a comprehensive disclosure document.

FINRA Rule 2111 - Suitability

While Reg BI applies to retail customer recommendations, FINRA Rule 2111 establishes three suitability obligations:

Suitability TypeWhat It Requires
Reasonable-basisThe recommendation is suitable for at least some investors - the product makes sense generally
Customer-specificThe recommendation is suitable for the specific customer based on their individual investment profile
QuantitativeThe series of recommended transactions, taken together, are not excessive for the customer (anti-churning)

Exam Tip: Gotchas

  • Reg BI applies to broker-dealer recommendations to retail customers only. It does not apply to institutional customers or self-directed trades.
  • FINRA suitability (Rule 2111) is a lower standard than Reg BI. Suitability requires the recommendation be "suitable"; Reg BI requires it be in the customer's "best interest."
  • Quantitative suitability targets churning. Excessive trading that generates commissions but not returns for the customer.

Know Your Customer (KYC) - FINRA Rule 2090

FINRA Rule 2090 requires firms to use reasonable diligence to know the essential facts about every customer.

A firm must know enough to:

  • Effectively service the account
  • Identify the person with authority to act on the account
  • Comply with applicable laws and regulations

Customer information collected includes:

  • Investment objectives
  • Risk tolerance
  • Financial situation (income, net worth)
  • Tax status
  • Time horizon
  • Liquidity needs
  • Other holdings

Exam Tip: Gotchas

  • KYC (Rule 2090) applies to every customer, not just those receiving recommendations. Even self-directed accounts require the firm to know essential facts about the customer.

What Constitutes a "Recommendation"?

Not every communication is a recommendation. Understanding the line matters:

IS a RecommendationIs NOT a Recommendation
Suggesting a specific security to buyProviding general financial education
Recommending an investment strategyResponding to an unsolicited inquiry about a specific security
Suggesting an account typeProviding research reports without a call to action

A recommendation is a communication that, based on its content, context, and manner of presentation, could reasonably be viewed as a suggestion to take action.

Think of it this way: If the firm is nudging the customer toward a specific action, it is a recommendation. If the customer came up with the idea on their own, it is unsolicited and neither Reg BI nor suitability applies.

Exam Tip: Gotchas

  • An unsolicited trade does not trigger Reg BI or suitability. The customer initiated the idea, not the firm. The firm must still execute the trade, but the best interest and suitability standards only apply to firm-initiated recommendations.
