Putting It Together: Rule Comparison at a Glance

A Series 6 firm selling mutual funds, variable contracts, and 529 plans operates under three supervisory rules simultaneously. This closing section pulls them together so the Function 2.4 scope lines up cleanly in your memory.

The core insight: these three rules are complementary, not alternative. A firm must satisfy all three.

What three supervisory rules govern a Series 6 firm?

Memory Aid:

• Supervision rule = SYSTEM (build the supervisory machine)
• Supervisory-control rule = SUPERVISE the SYSTEM (test whether the machine works)
• MSRB municipal supervision rule = MUNICIPAL parallel (same machine, municipal activities, Series 51 / 53 principals)

Exam Tip: Gotchas

• A Series 6 representative does not approve their own business. New accounts, account changes, and discretionary orders are routed to a registered principal qualified for the product. The representative obtains the approval; the principal gives it.

How do the supervision, supervisory-control, and municipal supervision rules work together?

A Series 6 firm that sells 529 plans through a Series 6 rep must satisfy all three rules:

• The supervision rule: general supervision of the rep and the firm's business, WSPs, and principal review of new accounts, account changes, correspondence, and transactions
• The supervisory-control rule: testing that the supervision is actually working (supervision of supervision)
• The MSRB municipal supervision rule: municipal-specific supervision of the 529 plan activity, with a Series 51 or Series 53 principal covering the municipal fund securities piece

In the firm's WSPs, these three regimes are typically integrated. The Series 26 principal approves mutual fund and variable contract activities; the Series 51 or Series 53 principal covers the 529 plan activities; and the firm separately checks that its supervision is working.

Think of it this way: Three rules, one firm. The Series 26 principal approves the mutual fund account; the Series 51 or Series 53 principal approves the 529 account; and the firm tests whether its supervision is doing its job. Every account and every approval feeds into the same integrated supervisory record.

Exam Tip: Gotchas

• The three rules are complementary, not alternative. A firm selling 529 plans through a Series 6 rep must satisfy the supervision rule, the supervisory-control rule, and the MSRB municipal supervision rule simultaneously. Satisfying one does not substitute for satisfying another.
• The Series 26 principal is NOT qualified to supervise the 529 plan side of the business. A firm that mixes investment-company business with municipal fund securities needs BOTH a Series 26 principal (for the mutual funds and variable contracts) AND a Series 51 or Series 53 principal (for the 529 plans, LGIPs, and ABLE accounts).

What are the key distinctions Function 2.4 questions test?

When you see a Function 2.4 question, the answer almost always turns on one of these distinctions:

• Principal vs. supervisor: only a registered principal signs the required written approvals (new accounts, account-designation changes, acceptance of discretion)
• Self-approval vs. independent approval: a representative routes business to a principal and never approves their own accounts
• Subscription-way check handling: the check is payable to the issuer, never to the broker-dealer or rep; "promptly transmit" means no later than noon of the next business day
• Supervision rule vs. supervisory-control rule: the supervision rule builds the system; the supervisory-control rule tests whether the system works
• FINRA vs. MSRB: non-municipal activities fall under the FINRA supervision and supervisory-control rules; municipal fund securities (529, LGIP, ABLE) fall under the MSRB municipal supervision rule with Series 51 or Series 53 principal qualification

Every written approval Function 2.4 tests traces back to one of those distinctions.

What are the most tested supervisory rule-comparison distinctions?

Exam Tip: Gotchas

• The supervision rule, supervisory-control rule, and MSRB municipal supervision rule are simultaneous requirements for a full-service Series 6 firm. They are not a menu; they are a stack.
• Supervising a 529 plan sale requires a Series 51 or Series 53 principal, not a Series 26 principal. Wrong principal qualification = MSRB municipal supervision rule violation.
• A representative obtains approvals; a principal gives them. A representative does not approve their own new accounts, account changes, or discretionary orders.
• Customer checks are safeguarded the same way across product lines. Payable to the issuer, promptly transmitted, never commingled.
• Every supervisory approval in this unit ultimately traces back to the customer account information rule's requirement that a registered principal signs the new-account record. That signature is the embodiment of the firm's supervisory system at the account level.
