What this chapter covers

Laws, Regulations, and Guidelines, Including Prohibition on Unethical Business Practices is one of 4 chapters in CoStudy's Series 66 bank, and it holds 121 of the bank's 260 multiple-choice questions — roughly 47% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.

Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.

10 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.

Backdating a client's new account form to make it appear an advisory agreement was signed earlier than it actually was is:

  1. An acceptable administrative correction as long as the client later ratifies the paperwork
  2. A falsification of records constituting an unethical practice and a recordkeeping violation
  3. Permitted if done to correct an honest clerical mistake discovered the same business day
  4. Irrelevant to securities regulation since it involves only internal firm paperwork

Answer: B — A falsification of records constituting an unethical practice and a recordkeeping violation

A) Client ratification doesn't cure falsified documentation. B) Correct — backdating is a falsification of records violation under both BD and IA recordkeeping regimes. C) Even a same-day 'correction' via backdating misstates the actual signing date and is improper. D) Recordkeeping accuracy is directly a securities regulatory matter.

The Series 66 exam is administered by which self-regulatory organization?

  4. MSRB as the self-regulatory organization overseeing the municipal securities marketplace

Answer: B — NASAA as the association of state securities administrators developing model exams

A) SEC is federal, not an SRO for exams. B) Correct — NASAA sponsors 63/65/66 (FINRA delivers). C) FINRA delivers but NASAA sponsors. D) MSRB is munis.

  2. A federal crime regardless of whether the underlying source of funds is itself legitimate
  3. Permitted if the customer notifies the firm in writing that the intent is not evasive
  4. A civil violation only, with no criminal exposure if the underlying source is lawful funds

  3. Has any single retail client in the state during the prior 12 months regardless of frequency
  4. Has any office presence in the state used only for administrative back-office functions

  2. The individual investment adviser representative providing advice to the client
  3. The custodian holding the client's assets and its regulatory capital position
  4. The broker-dealer executing trades on behalf of the advisory client's account

Answer: B — The individual investment adviser representative providing advice to the client

A broker-dealer that has no place of business in a state and deals exclusively with other broker-dealers is generally:

  1. Exempt from registration in that state under the institutional/no-place-of-business exemption
  2. Required to register in every state where any counterparty broker-dealer is located
  3. Required to register as an investment adviser instead of as a broker-dealer
  4. Subject to the same de minimis client-count exemption that applies to investment advisers

Answer: A — Exempt from registration in that state under the institutional/no-place-of-business exemption

B) The exemption specifically avoids this broad registration requirement. A) Correct — dealing exclusively with other BDs/institutions with no place of business qualifies for exemption. C) Nothing converts the BD into an IA. D) The BD exemption standard differs from the IA de minimis (client-count) test.

An investment adviser must deliver its Form ADV Part 2A brochure to a new client:

  1. At least 48 hours before entering the advisory contract, or at signing with a 5-day right to terminate without penalty

  3. Only upon the client's specific written request submitted after the first billing cycle
  4. At the end of the first full calendar year of the advisory relationship

A registered representative recommends a mutual fund to a customer without disclosing that the representative's firm receives revenue-sharing payments from the fund company. This omission is MOST likely a violation of:

  1. No rule, because revenue sharing is a private arrangement between firms not subject to disclosure
  2. The USA's unethical-practices provisions requiring disclosure of material conflicts of interest
  3. The customer protection rule governing segregation of customer securities and funds
  4. The federal Investment Company Act's diversification requirements for registered funds

Answer: B — The USA's unethical-practices provisions requiring disclosure of material conflicts of interest

A) Undisclosed compensation conflicts are squarely covered by unethical-practices/conflict disclosure rules. B) Correct — failure to disclose a material conflict of interest violates unethical-practices standards. C) That rule concerns custody, not compensation disclosure. D) Diversification requirements are unrelated to this disclosure issue.

  3. 10 years from the date of the adviser's initial SEC registration only
  4. Indefinitely, since no defined retention period applies to advisory records

Answer: B — 5 years from the end of the fiscal year in which the record was created, with the first 2 years in an easily accessible place

A) Understates the retention period. B) Correct — the standard 5-year retention, with the first 2 years readily accessible. C) Not tied to the initial registration date. D) A defined period does apply; records aren't retained indefinitely by default.
