SIE Suitability: Reg BI, Customer Profiles, and Investment Recommendations

Suitability and the best interest standard are among the most consistently tested regulatory concepts on the SIE. These questions test whether candidates understand the obligations broker-dealers have when making recommendations to retail customers — and how those obligations were upgraded by Regulation Best Interest in 2020.

From Suitability to Reg BI

Prior to June 2020, FINRA's suitability rule (Rule 2111) governed the standard of care for broker-dealer recommendations. Under the traditional suitability standard, a recommendation was permissible as long as it was suitable — meaning it was appropriate given the customer's financial situation, investment objectives, and risk tolerance. A product could be suitable without being the best available option for the customer.

Regulation Best Interest (Reg BI), adopted by the SEC and effective June 30, 2020, established a higher standard. Under Reg BI, broker-dealers must act in the best interest of the retail customer when making a recommendation of a securities transaction or investment strategy. This means the recommendation cannot place the financial or other interest of the broker-dealer ahead of the customer's interest.

Reg BI does not eliminate suitability analysis — it incorporates it and raises the floor. The SIE tests the distinction explicitly.

The Four Components of Reg BI

Reg BI is structured around four distinct obligations. Know all four.

1. Disclosure Obligation

Before or at the time of a recommendation, the broker-dealer must provide the retail customer with written disclosure of all material facts relating to the scope and terms of the relationship. This includes disclosures about:

• The capacity in which the firm is acting (broker-dealer vs. investment adviser)
• Fees and costs associated with the recommendation
• The type and scope of services provided
• Material limitations on products or services offered

The Form CRS (Customer Relationship Summary) is the primary vehicle for these disclosures for both broker-dealers and investment advisers. It is a standardized 2-page document designed to allow customers to compare providers.

2. Care Obligation

The broker-dealer must exercise reasonable diligence, care, and skill when making a recommendation. This involves:

• Understanding the potential risks, rewards, and costs of the recommended security
• Understanding the customer's financial situation, investment objectives, time horizon, and risk tolerance
• Determining that the recommendation is in the customer's best interest

The care obligation also requires that when there are multiple reasonably available options, the broker selects the one that is best for the customer — not merely one that is suitable.

3. Conflict of Interest Obligation

Broker-dealers must establish, maintain, and enforce written policies and procedures to identify and at a minimum disclose, or eliminate, all conflicts of interest associated with recommendations. Certain conflicts — such as those created by sales contests, quotas, bonuses, and differential compensation based on product type — must be mitigated, not merely disclosed.

4. Compliance Obligation

Firms must maintain written policies and procedures reasonably designed to achieve compliance with Reg BI. Senior management and compliance personnel are responsible for ensuring these systems are operationally effective.

Retail Customer Definition

Reg BI applies to retail customers — defined as natural persons (or their legal representatives) who receive a recommendation primarily for personal, family, or household purposes. Institutional investors are not retail customers for purposes of Reg BI.

This definition is tested: a recommendation to a pension fund manager does not trigger Reg BI; a recommendation to an individual investor's IRA does.

New Account Form and Know Your Customer

Before making any recommendations, a broker-dealer must obtain the information needed to fulfill its suitability and best interest obligations. FINRA Rule 4512 requires collection and maintenance of basic customer information, including:

• Investment objectives
• Risk tolerance
• Time horizon
• Tax status
• Liquidity needs
• Any other information the customer discloses

This is the Know Your Customer (KYC) obligation. The information collected on the new account form drives every subsequent suitability determination. If a customer provides false information, the broker-dealer's liability is reduced — but the firm still cannot proceed if red flags are apparent.

Risk Tolerance and Concentration Risk

Risk tolerance is the customer's capacity and willingness to bear investment risk. It is typically categorized as conservative, moderate, or aggressive. The exam tests whether specific products are appropriate for customers with stated risk profiles.

Concentration risk arises when too large a portion of a customer's portfolio is in a single security, sector, or asset class. Even if a single security is suitable, recommending that a customer put 80% of their liquid assets in it likely violates Reg BI because of the concentration risk it creates.

Anti-Churning and the Customer's Best Interest

Churning is excessive trading in a customer's account to generate commissions without regard for the customer's investment interests. Under Reg BI, even if each individual recommendation is in the customer's best interest, a pattern of recommendations that generates excessive costs relative to benefit can violate the care obligation.

The factors that determine whether trading is excessive include turnover ratio, cost-to-equity ratio, and overall cost burden relative to the customer's account size.
