Definition
Commission
Per-transaction compensation paid to broker-dealers and agents based on each trade executed, creating potential conflicts of interest between generating transactions and serving client interests. Differs from fee-based advisory compensation (typically a percentage of AUM). Subject to suitability obligations (Regulation Best Interest for retail customers) and reasonableness standards.
A broker-dealer agent earns a $200 commission on each stock trade executed for a client. This creates an inherent conflict: the agent profits more from frequent trading, potentially incentivizing excessive transactions even when staying invested would better serve the client. In contrast, a fee-based adviser charging 1% of AUM annually has no per-trade incentive.
Students often confuse commissions (per-transaction payments to broker-dealers/agents) with advisory fees (ongoing percentage of AUM paid to investment advisers). Commission-based compensation creates churning risk because the agent profits from each trade, while fee-based compensation removes the per-trade incentive and ties the adviser's pay to account value.
How is Commission tested on the exam?
- Identifying when commission-based compensation creates conflicts of interest or churning violations
- Distinguishing between commission-based broker-dealer compensation and fee-based advisory compensation
- Determining whether commission structures meet suitability and reasonableness standards
- Recognizing disclosure obligations when receiving commission compensation
- Understanding when excessive commissions violate fiduciary or suitability duties
Regulatory limits
Regulatory Limits
| Description | Limit | Notes |
|---|---|---|
| Reasonableness standard | Commissions must be reasonable and not excessive | No specific percentage cap exists; determined by industry standards and transaction complexity |
| Suitability requirement | Recommendations must meet FINRA suitability or, for retail customers, Regulation Best Interest | Regulation Best Interest replaced FINRA suitability for retail recommendations on June 30, 2020, and requires weighing costs |
| Disclosure obligation | Commission arrangements must be disclosed to clients | Material compensation arrangements must be disclosed in writing |
| Churning prohibition | Excessive trading to generate commissions is prohibited | Churning requires control over the account, excessive trading activity, and intent to generate commissions; separately, FINRA Rule 2111 quantitative suitability and Regulation Best Interest bar an excessive series of recommended transactions without requiring proof of control or intent |
Think of commissions like paying a taxi driver per turn they take: The more turns (trades) they make, the more they earn, even if a direct route (buy-and-hold) gets you there faster and cheaper. Per-Transaction = Potential Churning. Fee-based advisers are like Uber (flat rate): they profit when you reach your destination successfully, not from taking extra turns.
Practice questions
Test your understanding with the questions below. Pick an answer to reveal the explanation.
David, a risk-averse 55-year-old investor with a $300,000 portfolio, works with a commission-based broker. Over the past year, the broker executed 65 trades in David's account, generating $12,000 in commissions. David's account returned 3% while the S&P 500 returned 11%. The broker tells David that "active trading captures market opportunities." Meanwhile, David's colleague Emily, who also has a $300,000 portfolio, uses a fee-based adviser who charges 1% of AUM annually, executed 8 trades, and her account returned 10%. Which statement best describes this situation?
B is correct. This scenario illustrates the core conflict created by commission-based compensation. David paid $12,000 (4% of account value) for 65 trades that significantly underperformed the market, while Emily paid $3,000 (1%) for 8 trades that nearly matched market performance. The broker's per-transaction compensation created an incentive to trade excessively, which could amount to excessive trading under the quantitative component of Regulation Best Interest if the broker recommended the trades, even without control of the account, and to churning if the broker also controlled the account (65 trades is heavy activity for a risk-averse investor).
A is incorrect because positive absolute returns do not justify excessive trading that generates high commissions and underperforms benchmarks. The 8% underperformance is significant. C is incorrect because the compensation structures are not equivalent: David paid 4x more in costs and received inferior results, demonstrating how commission incentives can harm clients. D is incorrect because legal and disclosed compensation does not eliminate suitability or fiduciary violations. Excessive trading driven by commission incentives violates the reasonableness standard and potentially constitutes churning.
The Series 65 exam tests your ability to identify how commission-based compensation creates conflicts of interest that can lead to churning and suitability violations. Understanding the structural difference between per-transaction commissions (which incentivize trading volume) and fee-based compensation (which aligns adviser and client interests) is critical for recognizing prohibited practices.
What is the primary difference between commission-based compensation paid to broker-dealer agents and fee-based compensation paid to investment advisers?
B is correct. The fundamental difference is the payment structure and resulting incentives. Commission-based compensation pays the agent for each individual transaction, creating an incentive to maximize trading frequency (even when unnecessary). Fee-based advisory compensation typically charges a percentage of assets under management (AUM) annually, aligning the adviser's interests with the client's since both benefit from portfolio growth rather than transaction volume.
A is incorrect because commission-based compensation is legal and widely used by broker-dealers; it simply creates different conflicts than fee-based compensation. C is incorrect because both commission arrangements and advisory fee structures require disclosure to clients. Commissions must be disclosed per transaction or in advance, and advisory fees must be disclosed in Form ADV Part 2A. D is incorrect because commissions have no specific regulatory percentage cap; they must be "reasonable" based on industry standards, services provided, and transaction complexity.
The Series 65 exam frequently tests understanding of how different compensation structures create different conflicts of interest. Commission-based compensation is a core concept for identifying churning violations, suitability issues, and conflicts between broker-dealer and investment adviser business models. Recognizing that commissions incentivize trading volume while AUM fees incentivize portfolio growth is essential.
A broker-dealer agent recommends that a retail customer buy a corporate bond that pays the agent a $500 commission. The customer is risk-averse and seeking income, and the bond is investment grade with a 5% yield. The firm also offers a comparable bond with the same rating, yield and maturity that would pay the agent a $200 commission, and the agent never weighs it. Which statement is most accurate under Regulation Best Interest?
C is correct. Regulation Best Interest applies when a broker-dealer or its associated person recommends a securities transaction to a retail customer. Its care obligation requires a reasonable basis to believe the recommendation is in the customer's best interest based on the customer's investment profile and the potential risks, rewards, and costs of the recommendation, without placing the agent's financial interest ahead of the customer's. Never weighing a comparable, cheaper bond the firm offers, where the main difference is the agent's pay, does not meet that standard.
A is incorrect because matching the customer's objectives is not enough; the agent must also weigh cost and must not put a higher commission first. B is incorrect because Regulation Best Interest turns on a recommendation to a retail customer, not on how the agent is paid. D is incorrect because disclosure is only one of the rule's obligations; disclosing the commission does not satisfy the separate care obligation.
Since June 30, 2020, Regulation Best Interest, not the FINRA suitability rule, governs a broker-dealer's recommendations to retail customers. Expect questions testing that it requires weighing costs and conflicts and that disclosure alone does not satisfy it. Investment advisers owe a separate fiduciary duty under the Advisers Act regardless of how they are paid.
All of the following statements about commission-based compensation are accurate except
C is correct (the exception). Commission-based compensation does not eliminate suitability requirements. Regardless of how a broker-dealer or agent is compensated (commissions, fees, or other arrangements), they must still ensure that recommendations are suitable for the client based on the client's investment profile, objectives, risk tolerance, and financial situation. The compensation structure does not change the obligation, and for a retail customer Regulation Best Interest's care obligation applies in place of FINRA suitability, adding a duty not to put the agent's interest ahead of the customer's.
A is accurate: Commission-based compensation inherently creates a conflict because the agent earns more by executing more transactions, which may not align with the client's best interest of minimizing unnecessary trading costs. B is accurate: Churning (excessive trading to generate commissions) is a prohibited practice that violates both fiduciary duty and suitability standards, particularly when the agent has control over the account and trades excessively with intent to generate commissions. D is accurate: While no specific percentage cap exists for commissions, they must be "reasonable" based on the complexity of the transaction, services provided, and prevailing industry standards for similar transactions.
The Series 65 exam tests your understanding that suitability obligations apply regardless of compensation structure. Many candidates incorrectly believe that commission-based compensation or client knowledge of fees eliminates compliance requirements. Understanding that all recommendations must meet suitability or, for retail customers, Regulation Best Interest standards and that commissions must be reasonable is essential for identifying violations.
A broker-dealer agent recommends a mutual fund to a client that charges a 5.75% front-end load, from which the agent receives a 4% commission. An identical no-load mutual fund with the same investment strategy, holdings, and performance history is available, but the agent does not receive any commission on no-load funds. The client is a long-term investor seeking growth. Which of the following statements are accurate?
1. The agent has a conflict of interest between earning commission and recommending the lower-cost option
2. Disclosing the 4% commission by itself satisfies the agent's obligations under Regulation Best Interest
3. Under Regulation Best Interest, the agent must weigh the costs of the recommendation, including the load
4. Under investment adviser fiduciary standards, the adviser would be required to recommend the no-load fund
B is correct. Statements 1, 3, and 4 are accurate.
Statement 1 is true: The agent faces a clear conflict of interest. Recommending the load fund generates a 4% commission, while recommending the identical no-load fund generates no commission. This creates an incentive to recommend the higher-cost option despite it being financially worse for the client.
Statement 2 is false: Regulation Best Interest has separate disclosure and care obligations. Disclosing the commission meets only part of the disclosure obligation; it does not give the agent a reasonable basis to believe the recommendation is in the customer's best interest.
Statement 3 is true: The care obligation requires a reasonable basis to believe the recommendation is in the retail customer's best interest based on the customer's investment profile and the potential risks, rewards, and costs of the recommendation. With an identical no-load fund available, the 5.75% load is hard to justify.
Statement 4 is true: Under investment adviser fiduciary duty, the adviser would be required to recommend the no-load fund. Fiduciary duty requires acting in the client's best interest, and when two funds are otherwise identical, no other factor can outweigh the higher cost, so the adviser could not reasonably conclude the load fund is in the client's best interest. Disclosure of the conflict does not cure a recommendation that is not in the client's best interest.
The Series 65 exam tests your ability to apply Regulation Best Interest (for broker-dealers) and the investment adviser fiduciary duty to compensation conflicts. This question demonstrates how commission-based compensation creates conflicts, how those conflicts are managed differently under different regulatory frameworks, and why fiduciary duty is considered a higher standard. Understanding these distinctions is critical because investment advisers (the primary focus of Series 65) owe fiduciary duty regardless of how they are compensated.
