TL;DR: What You Need to Know

1
Fiduciary duty is THE defining characteristic of investment advisers and the most heavily tested concept on the Series 65. If you don't master this, you will fail the Laws & Regulations section.
2
The exam doesn't ask 'What is fiduciary duty?' It asks 'An IA does X, Y, Z. Which violates fiduciary duty?' You must recognize ethical violations in complex scenarios.
3
Three core duties: Care (competence), Loyalty (client's interest first), and Disclosure (reveal all conflicts). Each duty has specific requirements and prohibited practices.
4
Study strategy: 60% of time on scenario practice (identify violations), 30% on disclosure requirements (Form ADV), 10% on best interest regulation vs suitability.

Test-taker quote:

"I made B's and A's in all the other sections but the Reg's section is so heavily weighted that it still brought me down to a 74. I thought I understood fiduciary duty, but the scenario questions were way more subtle than I expected."

This is the concept that fails people. Take it seriously.

Why Fiduciary Duty Is the Most Tested Concept

Let's be honest. Fiduciary duty sounds straightforward until you're staring at a scenario question with four plausible answers. The Series 65 doesn't test whether you can define fiduciary duty. It tests whether you can identify subtle ethical violations when the IA's actions seem reasonable at first glance.

📊

Most Weighted Section Component

Fiduciary duty appears in 40% of Laws & Regulations questions (which is already 30% of the total exam). That's roughly 15 to 20 questions directly testing this concept.

⚖️

Legal Distinction Between Series 65 and Series 7

The fiduciary standard is what separates investment advisers (Series 65) from broker-dealers (Series 7). NASAA tests this distinction heavily because it defines your entire career path.

🤔

Scenario-Based Questions Are Tricky

Unlike 'calculate standard deviation' (one right answer), ethics questions involve judgment. The difference between 'allowed with disclosure' vs 'prohibited entirely' is subtle and trips up most candidates.

🎯

Career-Defining Knowledge

This isn't just exam content. Understanding fiduciary duty is foundational to your career as an investment adviser. NASAA wants to ensure you truly grasp these responsibilities before you advise real clients.

What Is Fiduciary Duty? (Legal Definition)

A fiduciary is someone who is legally and ethically bound to act in another person's best interest. For investment advisers, this means putting clients' interests ahead of your own in all matters related to the advisory relationship. The Investment Advisers Act of 1940 established this duty for all IAs.

The Three Pillars of Fiduciary Duty

🎓

Duty of Care

Competence and diligence. Adequate research before advising.

🤝

Duty of Loyalty

Client's interest first. No self-dealing or conflicts.

📋

Duty of Disclosure

Reveal all material facts and conflicts in writing.

Key Distinction:

Broker-dealers (Series 7) have a suitability standard. Investment advisers (Series 65) have a fiduciary standard. This is THE fundamental difference. Fiduciary = best interest. Suitability = appropriate but not necessarily best.

The Three Core Duties: Care, Loyalty, Disclosure

Every fiduciary scenario question tests one of these three duties. Master them, and you'll recognize violations immediately.

🎓

Duty of Care

Definition: The obligation to provide competent and diligent advice based on adequate research and analysis.

Requirements:

  • Reasonable basis for recommendations (due diligence)
  • Adequate research before advising clients
  • Ongoing monitoring of client portfolios
  • Stay informed about client's financial situation
  • Provide advice suitable to client's objectives and risk tolerance

Common Violations:

  • Recommending investments without understanding them
  • Failing to conduct adequate research
  • Not monitoring client accounts regularly
  • Ignoring changes in client circumstances

Exam Tip: Duty of care is about competence. If an IA recommends something without understanding it or without researching it, that's a violation.

🤝

Duty of Loyalty

Definition: The obligation to put the client's interests ahead of your own in all matters related to the advisory relationship.

Requirements:

  • Client's interest comes first, always
  • Avoid conflicts of interest where possible
  • If conflicts exist, disclose and obtain consent
  • No self-dealing or front-running client trades
  • Fair allocation of investment opportunities

Common Violations:

  • Recommending proprietary products without disclosure
  • Trading ahead of client orders (front running)
  • Excessive trading to generate fees (churning)
  • Accepting gifts that create obligations
  • Using client information for personal benefit

Exam Tip: Duty of loyalty is about who benefits. If the IA benefits more than the client, or uses client info for personal gain, it's a violation.

📋

Duty of Disclosure

Definition: The obligation to provide full and fair disclosure of all material facts, especially those that might affect the client's decision-making.

Requirements:

  • Disclose all conflicts of interest in writing
  • Provide Form ADV Part 2 before or at contract signing
  • Disclose compensation arrangements clearly
  • Update disclosures when changes occur
  • Use plain English, not legal jargon

Common Violations:

  • Failing to disclose referral fees
  • Not providing Form ADV to clients
  • Using vague or generic conflict disclosures
  • Omitting material facts that would influence client decisions
  • Disclosing conflicts verbally only (must be written)

Exam Tip: Duty of disclosure is about transparency. 'When in doubt, disclose' is the rule. Most violations involve not telling clients about conflicts.

Fiduciary Standard vs Suitability Standard (Complete Comparison)

This comparison is heavily tested. Know every row of this table. Questions will ask "Which is true of fiduciary duty but NOT suitability?" or vice versa.

Aspect Fiduciary (Series 65) Suitability (Series 7)
Legal Standard Must act in client's BEST interest Recommendation must be SUITABLE for client
Who It Applies To Investment Advisers (Series 65/66) Broker-Dealers (Series 7)
Regulatory Authority SEC (federal) and state securities regulators FINRA (self-regulatory organization)
Disclosure Obligation Proactive disclosure of ALL conflicts before engagement (Form ADV) Disclosure if client asks or if material to recommendation
Compensation Model Fee-based (AUM, retainer, hourly). No commissions in pure advisory. Commission-based (transaction fees). May receive product sales commissions.
Client's Interest First? YES. Client's interest ALWAYS comes before IA's interest. Not required. Broker can prioritize firm's products if suitable.
Ongoing Duty? YES. Continuous monitoring and updating of advice. NO. Point-in-time recommendation only (no ongoing duty).
Conflict Handling Must disclose in writing AND obtain informed consent. Some conflicts prohibited entirely. Disclose material conflicts. Can proceed if client doesn't object.

Real-World Example:

A client needs income. Fiduciary IA recommends the lowest-cost bond fund after researching all options (client's best interest). Suitability broker recommends the firm's proprietary bond fund with higher fees (suitable, but not necessarily best). Both are legal, but they represent fundamentally different standards.

SEC Regulation Best Interest (Reg BI) Explained

Reg BI (effective June 30, 2020) created a "best interest" standard for broker-dealers. It's higher than suitability but lower than full fiduciary duty. Know this distinction for the exam.

SEC Regulation Best Interest

Effective: June 30, 2020
Applies to: Broker-Dealers making recommendations to retail customers

Four Components:

  • Disclosure Obligation: Must disclose material facts about relationship, conflicts, and costs in plain English (Form CRS)
  • Care Obligation: Must exercise reasonable diligence and care to understand investment and client profile
  • Conflict of Interest Obligation: Must establish, maintain, and enforce policies to identify and mitigate conflicts
  • Compliance Obligation: Must establish written policies and procedures to achieve compliance

State Fiduciary Rules Trend

States are increasingly adopting fiduciary standards for all advisers. Examples:

  • Nevada (2017): First state fiduciary rule for broker-dealers
  • New Jersey (2020): Adopted fiduciary standard for annuity sales
  • Massachusetts: Proposed broad fiduciary rule

Impact: Even if you're a BD, you may have state-level fiduciary obligations. Check your state.

Key Exam Distinction:

Reg BI is "best interest" but NOT fiduciary duty. BDs can still earn commissions and recommend proprietary products if it's in the client's best interest. The ongoing monitoring duty that fiduciaries have does not apply to BDs under Reg BI.

10 Common Fiduciary Violations on the Series 65

These scenarios appear repeatedly on the exam. Memorize the pattern: What happened? Why is it wrong? What should have been done? Know whether each is "prohibited entirely" or "allowed with disclosure."

1

Principal Transactions Without Disclosure

Scenario: An IA sells its own securities to a client portfolio without telling the client it is selling from its own account.

Why it's wrong: Creates conflict of interest (self-dealing). The IA might prioritize getting rid of its own holdings over finding the best investment for the client.

Correct action: Must disclose in writing before transaction and obtain client's written consent. Some states require consent for each transaction.

Exam Tip: Any time an IA acts as principal (buying or selling its own securities to/from client), written disclosure and consent required.

2

Soft Dollar Arrangements for Firm Benefit Only

Scenario: An IA directs all client trades to Broker X in exchange for free research that only benefits the IA's separate hedge fund business (not the clients).

Why it's wrong: Violates duty of loyalty. Soft dollars are allowed only if the research or service benefits the clients, not just the IA.

Correct action: Soft dollars allowed if research benefits clients AND arrangement is fully disclosed. Must document benefit.

Exam Tip: Soft dollars are legal if they benefit clients and are disclosed. If only the IA benefits, it's a violation.

3

Borrowing Money from Clients

Scenario: An IA asks a wealthy retired client for a personal loan to buy a vacation home.

Why it's wrong: Prohibited unless client is a lending institution in the business of making loans. Creates improper relationship.

Correct action: Do not borrow from clients (except banks, credit unions, or lending institutions in that business).

Exam Tip: Lending or borrowing between IA and client is prohibited unless client is a bank or lending institution.

4

Accepting Excessive Gifts from Clients

Scenario: Client gives IA a $5,000 Rolex watch after a profitable year as a thank-you gift.

Why it's wrong: Creates obligation and impairs objectivity (violates duty of loyalty). Gifts can influence future recommendations.

Correct action: Decline or limit to nominal value. Many firms use $100 rule. Some prohibit all gifts. Must disclose to firm.

Exam Tip: Gifts create conflicts of interest. Most exam questions use 'reasonable value' or '$100 de minimis' rule.

5

Referral Arrangements Without Disclosure

Scenario: An IA receives $500 for each client referred to CPA firm Y, never mentions this compensation to clients.

Why it's wrong: Undisclosed conflict of interest (violates disclosure duty). Clients might think referral is unbiased.

Correct action: Disclose all referral fees in writing before making referral. Some states require separate referral agreement disclosure.

Exam Tip: ALL compensation arrangements must be disclosed, including referral fees, revenue sharing, solicitation arrangements.

6

Churning Client Accounts for Fees

Scenario: An IA with discretionary authority makes excessive trades in client accounts to increase AUM-based management fees.

Why it's wrong: Violates duty of loyalty. Trading for IA's benefit (fees), not client's benefit (returns).

Correct action: Trade only when in client's best interest. Document rationale for all discretionary trades.

Exam Tip: Excessive trading to generate fees is always prohibited. 'Churning' applies to both commissions and AUM fees.

7

Front Running Client Trades

Scenario: An IA learns a large institutional client will buy 100,000 shares of Stock X tomorrow. IA buys 10,000 shares for own account today.

Why it's wrong: Violates duty of loyalty. Using client information (material non-public order info) for personal gain. This is fraud.

Correct action: Never trade ahead of client orders. Never use client information for personal benefit.

Exam Tip: Trading ahead of clients (front running) is fraud, not just an ethics violation. Automatic disqualification.

8

Recommending Proprietary Products Without Disclosure

Scenario: An IA recommends the firm's own mutual funds to all clients without disclosing the proprietary relationship or comparing to competitors.

Why it's wrong: Conflict of interest not disclosed (violates disclosure duty). IA may earn more from proprietary products.

Correct action: Disclose proprietary relationship in writing, compare to alternatives, document why proprietary product is best for this client.

Exam Tip: Proprietary products require clear disclosure of conflict AND rationale for why it's best for client.

9

Commingling Client Funds

Scenario: An IA deposits client checks into the firm's operating account temporarily 'for convenience' before transferring to custodian.

Why it's wrong: Custody violation. Creates fraud risk and violates segregation requirements. Even temporary commingling is prohibited.

Correct action: Never commingle client assets with firm assets. Client funds go directly to qualified custodian.

Exam Tip: Commingling is always prohibited, even temporarily. Custody rule violations are heavily tested.

10

Guaranteeing Investment Results

Scenario: An IA tells a prospect during a sales pitch: 'I guarantee you'll earn at least 10% annual returns if you hire me.'

Why it's wrong: Fraudulent and violates duty of care. No one can guarantee specific investment returns. Creates unrealistic expectations.

Correct action: Never guarantee specific returns. Can show historical performance with proper disclaimers.

Exam Tip: Guarantees of any kind are always prohibited in advisory relationships. Immediate red flag on exam.

Disclosure Requirements: What You Must Tell Clients

Disclosure is the third pillar of fiduciary duty. Know what must be disclosed, when, and in what format. Form ADV timing is heavily tested.

Form ADV Part 2 (The Brochure)

  • Business practices and types of services offered
  • Fee schedule and calculation methods

Updates: Within 30 days of material change

How to Identify Conflicts of Interest (4-Step Framework)

Use this framework when answering scenario questions. It will help you systematically identify whether a conflict exists and what must be done.

1.

Identify Potential Conflicts

Recognize situations where your interests might not align perfectly with client's interests.

  • Proprietary products (you earn more if client buys your firm's funds)
  • Referral fees (you get paid for sending clients elsewhere)
  • Dual roles (you're both adviser and broker for same client)
  • Personal trading (you trade same securities as clients)
  • Affiliated services (you refer to firm's CPA, lawyer, etc.)

Exam Tip: If you ask 'Could I benefit from this?', it's probably a conflict.

2.

Evaluate Materiality

Assess whether the conflict is material enough to influence your advice or client's decision-making.

  • Would a reasonable client want to know about this?
  • Could this affect my objectivity in giving advice?
  • Do I earn more/less based on this recommendation?
  • Would this change the client's decision?

Exam Tip: When in doubt, assume it's material. Better to over-disclose than under-disclose.

3.

Disclose in Writing

Communicate the conflict clearly in Form ADV Part 2 or separate written disclosure.

  • Use plain English, not legal jargon
  • Be specific, not vague generic statements
  • Explain how conflict is managed or mitigated
  • Disclose BEFORE engaging in conflicted transaction
  • Make disclosure prominent, not buried in fine print

Exam Tip: Bad: 'We may have conflicts.' Good: 'We earn a 1% referral fee for each client we refer to ABC Tax Services.'

4.

Manage or Avoid Conflict

After disclosure, obtain informed consent or avoid the conflict entirely.

  • Obtain client's informed written consent to proceed
  • Avoid the conflict entirely (don't engage in transaction)
  • Implement safeguards (independent review, best execution policies)
  • Monitor ongoing to ensure client isn't harmed

Exam Tip: Some conflicts require disclosure + consent. Others are prohibited even with disclosure (like borrowing from clients).

Prohibited Practices Under Fiduciary Duty

These practices are prohibited entirely (not just "disclose and proceed"). Memorize these categories. Any scenario involving these is automatically a violation.

🏦

Custody Rule Violations

  • Taking physical possession of client funds or securities without being a qualified custodian
  • Having authority to withdraw funds from client accounts (inadvertent custody)
  • Not arranging for surprise audits when you have custody
  • Commingling client assets with firm assets
  • Exception: Automated fee deduction is allowed with proper client authorization and notice
💰

Performance Fee Violations

  • Charging performance fees to non-qualified clients
  • Qualified client thresholds: $1 million or more with the IA OR $2.5 million or more net worth
  • Not using proper calculation method (must compare to benchmark)
  • Not disclosing calculation method and risks clearly
  • Charging performance fees without meeting exemption requirements
⚠️

Fraudulent and Deceptive Practices

  • Guaranteeing specific investment results to clients
  • Churning accounts (excessive trading to generate fees)
  • Unauthorized trading without proper discretionary authority
  • Misrepresenting credentials, qualifications, or experience
  • Promising specific returns ('I guarantee 10% annually')
  • Front running client trades
  • Scalping (buying before recommending, then selling into demand)
🤝

Sharing in Client Profits or Losses

  • Generally prohibited for standard advisory arrangements
  • Exception: If you have written approval from both the client AND the IA firm
  • Must be proportional to capital contribution
  • Cannot use arrangement to shift inappropriate risk to clients
  • Hedge fund managers have different rules (performance fees allowed for qualified clients)
📢

Advertising Violations

  • Using client testimonials (prohibited for IAs, allowed for BDs with disclosures)
  • Making past performance claims without proper disclaimers
  • Cherry-picking results and omitting poor performance periods
  • Making unsubstantiated claims about expertise or returns
  • Using misleading charts or graphics that distort performance
  • Comparing to inappropriate benchmarks

How the Series 65 Tests Fiduciary Duty

The exam uses three main question patterns. Recognize these patterns and you'll answer faster and more accurately.

Multi-Step Ethics Scenarios

Question describes a situation with multiple actions. You must identify which specific action violates fiduciary duty.

Example question:

An investment adviser: (I) recommends the firm's proprietary mutual fund, (II) discloses the relationship in Form ADV, (III) compares fees to competitors, (IV) documents rationale. Which violates fiduciary duty?

Correct Answer: None (all steps followed correctly)

Common Trap: Candidates think proprietary products are always prohibited. They're allowed WITH disclosure and rationale.

Approach: Evaluate each action separately. Identify if disclosure present, if conflict managed, if client harmed.

Disclosure Timing Questions

Question asks WHEN disclosure must occur (before, during, after transaction).

Example question:

An IA plans to sell securities from its own account to a client. When must the IA disclose this principal transaction?

Correct Answer: Before the transaction, in writing, and obtain client consent

Common Trap: Candidates think verbal disclosure or disclosure after transaction is acceptable.

Approach: Fiduciary disclosures = BEFORE + IN WRITING. If it's a conflict, disclose proactively.

Conflict Identification

Question describes a complex scenario. You must identify whether a conflict of interest exists.

Example question:

An IA's spouse is a CPA. The IA occasionally refers clients to the spouse for tax preparation but receives no compensation. Is this a conflict of interest that must be disclosed?

Correct Answer: Yes, must disclose (family relationship creates potential bias)

Common Trap: Candidates think 'no compensation' means 'no conflict.' Family relationships are conflicts.

Approach: Ask: 'Would a reasonable client want to know this?' If yes, it's a conflict requiring disclosure.

Study Strategies for Mastering Fiduciary Concepts

Fiduciary duty requires different study tactics than investment math. You need pattern recognition and scenario practice, not just memorization.

1.

Master the Three Core Duties Framework

Create a visual diagram showing Care, Loyalty, Disclosure branches with specific requirements under each. Use this as your mental model for all scenario questions.

  • Make flashcards: front = scenario, back = which duty violated + why
  • Teach the framework to a study partner to solidify understanding
  • Write out 5 examples of violations for each duty

Time allocation: Week 1: 20% of fiduciary study time (3 hours)

2.

Practice 300+ Fiduciary Scenario Questions

Focus exclusively on ethics and fiduciary duty questions in your question bank. Aim for 300 to 400 questions specifically on this topic.

  • Read ALL answer explanations, even for questions you got right
  • Note patterns: What makes an answer 'prohibited' vs 'allowed with disclosure'?
  • Review missed questions twice: once immediately, once 3 days later

Time allocation: Weeks 1-2: 50% of fiduciary study time (7 to 8 hours)

3.

Create Your Own Violation Scenarios

Write 10 scenarios: 'An IA does [action]. Is this allowed?' Create 5 violations and 5 allowed-with-disclosure examples.

  • Trade scenarios with study partner and quiz each other
  • Explain WHY each is a violation (which duty, what harm)
  • Use real-world examples from news (SEC enforcement actions)

Time allocation: Week 1: 15% of fiduciary study time (2 hours)

4.

Memorize Disclosure Requirements

Know Form ADV Part 2 timing, content, and update requirements cold. Know what must be disclosed proactively vs only if asked.

  • Create timeline chart: 'At engagement' vs 'Annually' vs 'When changes occur'
  • Link each disclosure to consequences of non-disclosure
  • Make mnemonic for Form ADV Part 2 contents

Time allocation: Week 1: 10% of fiduciary study time (1.5 hours)

5.

Compare Fiduciary vs Suitability Daily

Review the side-by-side comparison table every study session. Focus on differences in real-world application, not just textbook definitions.

  • Ask: 'What would a fiduciary do?' vs 'What would a broker do?'
  • Understand ongoing duty difference (continuous vs point-in-time)
  • Know Reg BI as 'middle ground' between suitability and fiduciary

Time allocation: Ongoing: 5% of fiduciary study time (daily 10-minute review)

Common Mistakes When Studying Fiduciary Duty

Mistake 1: Confusing 'Allowed with Disclosure' vs 'Prohibited Entirely'

Why it fails:

Many actions (like principal transactions) are allowed IF properly disclosed and consented to. Others (like borrowing from clients) are prohibited even with disclosure.

Better approach:

Create two lists: 'Allowed with Disclosure' (principal trades, proprietary products, referral fees) vs 'Prohibited Entirely' (borrowing from clients, guarantees, commingling).

Exam Impact: This distinction is tested heavily. Wrong categorization = wrong answer.

Mistake 2: Not Recognizing Subtle Conflicts of Interest

Why it fails:

Candidates miss conflicts when there's no direct payment. Example: Referring to spouse's business (conflict even with no fee).

Better approach:

Use 'reasonable client' test: Would a reasonable client want to know about this relationship or arrangement? If yes, disclose it.

Exam Impact: Subtle conflicts appear in 30% to 40% of ethics questions. Missing them costs points.

Mistake 3: Overthinking Ethics Questions

Why it fails:

Candidates look for trick answers when the question is straightforward. 'An IA guarantees 10% returns. Is this allowed?' Answer: No, it's always prohibited.

Better approach:

Start with the simple rule. If an action clearly violates a core duty, don't overthink exceptions.

Exam Impact: Overthinking causes you to change correct answers to wrong ones. Trust your first instinct on clear violations.

Mistake 4: Memorizing Rules Without Understanding 'Why'

Why it fails:

Rote memorization fails on scenario questions. You need to understand WHY borrowing from clients is prohibited (creates improper relationship).

Better approach:

For each rule, ask: 'What harm could this cause?' or 'Why does this rule exist?' Connect rules to the three duties.

Exam Impact: Understanding 'why' helps you apply rules to new scenarios you haven't seen before.

Mistake 5: Ignoring Best Interest Regulation Updates

Why it fails:

Reg BI (2020) changed the landscape. Some candidates study old materials that don't cover this.

Better approach:

Know Reg BI basics: applies to BDs, creates 'best interest' standard (between suitability and fiduciary), requires Form CRS.

Exam Impact: 2 to 4 questions may test Reg BI vs fiduciary duty distinction. Easy points if you know it.

Mistake 6: Assuming Fiduciary Duty = Suitability Standard

Why it fails:

These are different standards. Suitability = recommendation is appropriate. Fiduciary = client's BEST interest, ongoing duty.

Better approach:

Memorize comparison table. Focus on 'best interest' vs 'suitable', ongoing vs point-in-time, proactive disclosure vs if-asked.

Exam Impact: Questions explicitly test this distinction. 'Which is true of fiduciary duty but NOT suitability?'

Mistake 7: Not Practicing Enough Scenario Questions

Why it fails:

Reading about fiduciary duty is different from applying it. Scenario questions require pattern recognition.

Better approach:

Do 300+ ethics scenario questions. Review every wrong answer. Create your own scenarios to test understanding.

Exam Impact: Most fiduciary questions are scenarios, not definitions. Without practice, you'll struggle even if you know the theory.

Mistake 8: Failing to Distinguish Material vs Immaterial Conflicts

Why it fails:

Not every potential conflict is material. Example: IA and client both own Apple stock (not a conflict requiring disclosure).

Better approach:

Material = could reasonably influence advice or client decision. Use 'reasonable client' test.

Exam Impact: Questions test whether specific conflicts must be disclosed. Over-disclosure and under-disclosure are both wrong.

Mistake 9: Forgetting Ongoing Disclosure Obligations

Why it fails:

Candidates think Form ADV is one-time. It must be updated annually and when material changes occur.

Better approach:

Know triggers: annual update, material change, client request. Memorize 'within 90 days annually' and 'promptly when material change.'

Exam Impact: Timing questions are easy points. 'When must an IA update Form ADV?' Know this cold.

Mistake 10: Mixing Up Form ADV Timing Requirements

Why it fails:

Part 1 (registration) has different timing than Part 2 (brochure). Candidates confuse them.

Better approach:

Part 1 = registration, annual update within 90 days of fiscal year end. Part 2 = client brochure, deliver at or before engagement, annually thereafter.

Exam Impact: Form ADV questions are highly testable. Know Part 1 vs Part 2 timing.

Fiduciary Duty FAQ: 17 Common Questions Answered

1. What is the difference between fiduciary duty and suitability?

Fiduciary duty requires acting in the client's BEST interest with ongoing obligations. Suitability (for broker-dealers) requires recommendations to be suitable for the client, but allows prioritizing firm products and has no ongoing duty. Fiduciary = higher standard.

2. Can an investment adviser ever act as principal in a transaction with a client?

Yes, but only with full written disclosure before the transaction and written client consent. Many states require transaction-by-transaction consent. This is 'allowed with disclosure,' not prohibited entirely.

3. Are soft dollar arrangements always prohibited?

No. Soft dollars are allowed if: (1) the research or service benefits clients (not just the IA), and (2) the arrangement is fully disclosed to clients. If only the IA benefits, it's a breach of fiduciary duty.

4. What must be disclosed in Form ADV Part 2?

Business practices, services offered, fee schedules, conflicts of interest, disciplinary history (past 10 years), affiliated services, code of ethics, brokerage practices, and soft dollar arrangements. Must be delivered at or before entering the advisory contract.

5. Can an investment adviser borrow money from a client?

No, unless the client is a financial institution in the lending business (bank, credit union, etc.). Personal loans between IAs and clients are prohibited to avoid conflicts of interest and inappropriate relationships.

6. What is the 'best interest' standard under Regulation Best Interest (Reg BI)?

Reg BI (effective June 30, 2020) requires broker-dealers to act in the retail customer's best interest when making recommendations. It's higher than suitability but not full fiduciary duty. BDs must disclose conflicts, exercise care, and mitigate conflicts.

7. How do I identify conflicts of interest in scenario questions?

Use the 'reasonable client' test: Would a reasonable client want to know about this arrangement or relationship? If yes, it's a conflict requiring disclosure. Examples: proprietary products, referral fees, family relationships, personal trading.

8. Can an investment adviser accept gifts from clients?

Generally discouraged. Gifts create obligations and impair objectivity. Many firms use a de minimis rule (e.g., $100 limit). Anything beyond nominal value should be declined or disclosed to the firm. Some firms prohibit all gifts.

9. What is the difference between duty of care and duty of loyalty?

Duty of care = competence (adequate research, ongoing monitoring, reasonable basis). Duty of loyalty = putting client's interest first (no self-dealing, no conflicts without disclosure). Care = 'am I competent?' Loyalty = 'who benefits?'

10. Do fiduciary duties apply to ALL client interactions?

Yes. Once an advisory relationship exists, the fiduciary duty applies to all advice and interactions related to that relationship. It's not limited to specific transactions. The duty is ongoing, not point-in-time.

11. What happens if an investment adviser fails to disclose a conflict of interest?

Undisclosed conflicts breach fiduciary duty and can constitute fraud. Consequences: SEC/state enforcement actions, fines, disgorgement of fees, suspension or revocation of registration, civil lawsuits, and even criminal charges in severe cases.

12. Can an investment adviser charge performance fees?

Yes, but only to qualified clients: those with $1 million or more under management with the IA OR $2.5 million or more net worth. Performance fees must use proper calculation methods and be fully disclosed. Not allowed for non-qualified clients.

13. How often must Form ADV be updated?

Annually within 90 days of fiscal year end. Also must be updated promptly (within 30 days) when material changes occur. Clients must receive updated brochure (Part 2) annually and when material changes occur.

14. What is front running and why is it prohibited?

Front running is trading ahead of client orders to profit from the anticipated market movement. Example: IA learns client will buy 100,000 shares, IA buys for own account first. This is fraud (using client information for personal gain) and violates duty of loyalty.

15. Can an investment adviser recommend proprietary products?

Yes, but must fully disclose the proprietary relationship and conflict of interest. Must compare to alternatives and document why the proprietary product is best for this specific client. Cannot just recommend proprietary products to everyone without justification.

16. What is commingling and why is it prohibited?

Commingling is mixing client funds with the firm's operating funds. Always prohibited, even temporarily, because it creates fraud risk and violates custody rule segregation requirements. Client funds must go directly to a qualified custodian, never to the IA's accounts.

17. How do state fiduciary rules differ from SEC rules?

State-registered IAs follow state securities laws (Uniform Securities Act model). SEC-registered IAs follow federal law (Investment Advisers Act of 1940). Both impose fiduciary duty, but states may have additional requirements. Some states (Nevada, New Jersey) expanded fiduciary standards beyond federal minimums.
