Quick Answer
Know-your-customer (KYC) always applies; suitability applies only when a recommendation is made. Recommendations to retail customers (natural persons for personal use) fall under Regulation Best Interest (Reg BI); institutional recommendations stay under the FINRA suitability rule. Reg BI has four obligations; suitability has three cumulative obligations. Form CRS is delivered to retail investors so they can compare firms.
The whole unit on one sheet: which standard applies, the three suitability layers, and Reg BI's four obligations.
Which Rule Applies?
- KYC rule: always on, every account, recommendation or not. Gathers essential facts to service the account, follow special-handling instructions, know each person's authority, and comply with the rules.
- FINRA suitability rule: triggered by a recommendation; governs non-retail (institutional) recommendations.
- Reg BI: triggered by a recommendation to a retail customer (a natural person, or non-professional legal rep of one, using it primarily for personal, family, or household purposes). Absorbs and exceeds suitability.
- A recommendation can be to buy, sell, hold, or adopt a strategy involving securities.
What Are the Three Cumulative Suitability Obligations?
- Reasonable-basis: understand the product. Can attach before any customer exists. Is it OK for at least some investors?
- Customer-specific: match to this customer's investment profile.
- Quantitative: the series of trades is not excessive. No control requirement (removed in 2020); control plus intent is the separate churning (fraud) charge.
What Are Reg BI's Four Obligations?
- Disclosure: full and fair written disclosure before or at the time of the recommendation (relationship, fees, conflicts; identify BD status).
- Care: mirrors the three suitability layers, but the standard is best interest, not merely suitable.
- Conflict of Interest: identify conflicts, then disclose, mitigate, or eliminate.
- Compliance: written policies and procedures to achieve overall Reg BI compliance.
- All four required; complying with some but not all is not a safe harbor.
Which One-Liners Win Exam Points?
- "Hold" is a recommendation. "Stay in that fund" triggers suitability under the customer's current profile, not the profile at purchase.
- A strategy is a recommendation even with no specific security named (dollar-cost averaging, laddering, sector rotation).
- Reg BI is "at the time of the recommendation," not a continuous fiduciary duty. The Investment Advisers Act imposes the ongoing fiduciary standard.
- Sales contests, quotas, and non-cash comp tied to specific securities in a limited period must be ELIMINATED, not just disclosed.
- Retail investor (Form CRS) is broader than retail customer (Reg BI): a prospect who has not yet received a recommendation still gets Form CRS.
- Negative consent is never affirmation: silence does not waive customer-specific suitability.

What Are the Nine Profile Factors?
Age; other investments; financial situation and needs; tax status; investment objectives; investment experience; investment time horizon; liquidity needs; risk tolerance; plus any other information the customer discloses. Risk tolerance and time horizon are the two factors most often dropped; both are required.
What Is the Institutional-Customer Exemption?
- Waives customer-specific suitability only. Reasonable-basis always applies; quantitative suitability is not waived either.
- All three conditions: institutional-account status (listed entity or $50 million in assets), a reasonable belief the customer can evaluate risk independently, and the customer's affirmative indication of independent judgment.
What Are the Municipal and Tool Overlays?
- MSRB municipal-suitability rule: the muni parallel to FINRA suitability, covering 529 plans, Local Government Investment Pools (LGIPs), and Achieving a Better Life Experience (ABLE) accounts. Same three obligations. Tax status is a red flag for a low-bracket customer, not automatically determinative. It does not apply where Reg BI does.
- Investment-analysis-tool rule: governs interactive tools that simulate outcomes. Requires written disclosure of methodology, limitations, assumptions, universe of investments, and revenue bias. Additive to the suitability rules, not a substitute.
Which Gotchas Show Up Most?
- The three suitability obligations are cumulative, not alternative. Passing reasonable-basis but failing customer-specific is still unsuitable.
- A customer's refusal to share does not close the account: it stops recommendations. The firm may still open the account and take unsolicited orders; document it.
- Reg BI applies to retail only. A corporate pension plan, bank treasury desk, or hedge fund gets the FINRA suitability rule, not Reg BI.
- A rollover recommendation triggers Form CRS on its own, even if no new account is opened.
- The investment-analysis-tool access trigger is "upon request" only. There is no first-use clock and no template-filing deadline.
- The MSRB rule does not stack. A retail 529 sale with a Monte Carlo tool activates Reg BI, Form CRS, and the tool rule only.
One-Breath Recap
Ask two questions: was a recommendation made, and who is the customer. No recommendation means Know Your Customer only; a recommendation to a retail natural person means Regulation Best Interest (four obligations) plus Form CRS, while an institutional recommendation stays under the FINRA suitability rule unless the exemption waives customer-specific. Remember hold is a recommendation, sales contests get eliminated, the tool rule stacks on top, and the municipal rule does not.
