A municipal bond sales representative is creating a marketing brochure to attract new institutional clients. The brochure highlights the tax advantages and high credit ratings of several recent municipal bond issues, but it omits any mention of market risk, interest rate risk, or liquidity concerns. Which MSRB rule is most directly violated by this marketing practice?

Worked Practitioner Scenario

Practitioner Application: Retail Communications, Correspondence, and Institutional Communications

A registered representative sends a personalized email to 25 existing clients, discussing a new investment product. Simultaneously, the firm's marketing department publishes a blog post on its website, accessible to the general public, detailing the same product. Separately, a senior institutional salesperson emails a single qualified institutional buyer (QIB) a detailed analysis of a complex derivative. The compliance department needs to determine which of these communications require principal pre-use approval and which can be reviewed post-use, or if any are exempt, to avoid FINRA violations. Misclassifying even one communication type could lead to significant regulatory penalties.

  1. FINRA Rule 2210 governs all communications with the public by member firms and their associated persons. The rule categorizes communications into three primary types: retail communications, correspondence, and institutional communications, each with distinct definitions, approval requirements, and recordkeeping obligations. Understanding these distinctions is crucial for compliance and for the Series 7 exam.
  2. Retail Communication is defined as any written (including electronic) communication distributed or made available to more than 25 retail investors within any 30-calendar-day period. A retail investor is any person other than an institutional investor. This category includes advertisements, sales literature, and independently prepared reprints (IPRs). Due to its broad reach, retail communication generally requires principal pre-use approval.
Correspondence is defined as any written (including electronic) communication distributed or made available to 25 or fewer retail investors within any 30-calendar-day period. This category often includes personalized emails, letters, and instant messages. While principal pre-use approval is not always required, firms must establish appropriate supervisory procedures, which may include pre- or post-use review.
