SERIES 66: LAWS, REGULATIONS & GUIDELINES — CHEAT SHEET

REGULATORY FRAMEWORK

|-----------|--------------|----------|

---

INVESTMENT ADVISER vs. BROKER-DEALER

|-----------|---------------------------|----------------------|

---

FIDUCIARY DUTIES (IARs & IAs)

Two Core Duties:

  • Duty of Loyalty
  • - Act solely in client's best interest - Disclose all conflicts of interest - No self-dealing; no undisclosed commissions
  • Duty of Care
  • - Conduct adequate investigation (suitability, know-your-client) - Manage assets prudently - Maintain competence in services offered

    Cannot waive fiduciary duty — any attempt to limit liability is void.

    ---

    REGISTRATION REQUIREMENTS

    SEC Registration Thresholds

    |-----|------------------------|

    State Registration (Uniform Securities Act)

    • Notice filing — supplement federal registration in states where IA has clients
    • State law supplement applies; state can impose stricter rules
    • Brochure (Form ADV Part 2A) — must deliver to all clients before engagement

    ---

    ADV FORMS & DISCLOSURE

    |------|---------|------|

    Key Rule: Deliver brochure before or at engagement; client has right to refuse and cancel within 5 days.

    ---

    FEES & COMPENSATION RULES

    Prohibited Fee Structures

    • Performance fees (based on gains/losses) — PROHIBITED for non-qualified clients
    • Soft dollars used to pay for services not connected to research/execution
    • Undisclosed third-party compensation (kickbacks, revenue sharing)

    Permitted Structures

    • AUM fees (1–2% typical) — most common; may decline with assets
    • Flat fees (e.g., $5,000/year) — transparent
    • Hourly fees — straightforward
    • Performance fees — ONLY for qualified clients (≥$750K AUM or ≥$1.5M net worth)

    Disclosure: Must disclose fee structure, breakpoints, and any unusual charges in ADV Part 2A.

    ---

    CUSTODY & CLIENT ASSETS

    Custody Rules (for Advisers Holding Client Money/Securities)

  • Separate account — Client assets segregated; never commingled with firm assets
  • Third-party custody — Best practice: custodian (bank/broker) holds assets; adviser has no physical custody
  • Quarterly statements — If adviser has custody, must send quarterly statements to clients
  • Surprise audit — Must undergo annual surprise audit by independent CPA if holding client assets
  • Net worth requirement — Adviser holding custody must maintain minimum net worth ($35K per location or $1M aggregate)
  • Red Flag: If adviser requires you to send checks directly to the firm (not a custodian), that's unusual and increases fraud risk.

    ---

    SUITABILITY & KNOW-YOUR-CLIENT (KYC)

    KYC Information Required

    • Age, investment experience, income, net worth
    • Investment objectives (growth, income, safety)
    • Time horizon and risk tolerance
    • Other assets and liabilities
    • Tax situation
    • Must be documented and updated regularly (at least annually)

    Suitability Standard

    • Recommendation must be suitable given client's profile
    • Not required to be the "best" option, but must have reasonable basis
    • BD & IA must document basis for suitability

    Fiduciary Standard (IAs Only)

    • More stringent than suitability
    • IA must recommend the best option for the specific client
    • IA owes undivided loyalty
