Disclosure obligations. This is in response to your letters dated March 18, 1998 and March 31, 1998 in which you present an example where a dealer advertises a specific municipal security which it knows, or has reason to know, is subject to a material adverse circumstance such as a technical default. You ask whether a dealer is obligated to include disclosure information indicating that a bond is subject to additional risk in order to avoid publishing a false or misleading advertisement as prohibited by rule G-21(c). The Board reviewed your letters and has authorized this response.
Section (c) of rule G-21 provides, among other things, that no dealer shall publish any advertisement concerning municipal securities which such dealer knows or has reason to know is materially false or misleading. The Board has previously interpreted the rule as not requiring that any specific statements or information be included in an advertisement but that any statement or information that is included must not be materially false or misleading. Thus, if a dealer makes a statement in an advertisement that explicitly or implicitly refers to the soundness or safety of an investment in the municipal securities described in the advertisement, such dealer must include any information necessary to ensure that the advertisement is not materially false or misleading with respect to the soundness or safety of such investment. The rule establishes a general ethical standard that provides the enforcement agencies with the flexibility that is needed to evaluate advertisements in light of what information is printed and how the information physically is presented. Thus, the enforcement agencies should continue to evaluate advertisements on a case-by-case basis to make a determination whether any such advertisements, in fact, are misleading.
You also ask whether the relative specificity of any such disclosure obligation that may exist depends on the level of detail provided about the municipal security. As stated above, rule G-21 does not require that any specific statements or information be included in an advertisement but that any statement or information that is included must not be materially false or misleading. Thus, the nature and extent of any disclosures or other explanatory statements that must be included in an advertisement is dependent upon the substance and form of the information presented in the advertisement.
The Board wishes to emphasize that the enforcement agencies should remain cognizant of certain other rules of the Board that may be relevant in evaluating whether a dealer's advertisement and such dealer's interactions with customers or potential customers that arise as a result of such advertisement are in conformity with Board rules. Thus, depending upon the facts and circumstances, an advertisement for a particular municipal security that on its face conforms with the requirements of rule G-21 may nonetheless be violative of rule G-17, the Board's fair dealing rule, if, for example, the advertisement is designed as a “bait-and-switch” mechanism that attracts potential customers interested in an advertised security that the dealer is not in a legitimate position to sell (because of its unavailability, unsuitability or otherwise) for the primary purpose of creating a captive audience for the offering of other securities. In addition, a dealer that in fact sells the municipal securities that are described in its advertisement must fulfill its obligations under rule G-19, on suitability, and rule G-30, on pricing. MSRB interpretation of May 21, 1998.
 “Advertisement” is defined in rule G-21 as any material (other than listings of offerings) published or designed for use in the public, including electronic, media, or any promotional literature designed for dissemination to the public, including any notice, circular, report, market letter, form letter, telemarketing script or reprint or excerpt of the foregoing. The term does not apply to preliminary official statements or official statements, but does apply to abstracts or summaries of official statements, offering circulars and other such similar documents prepared by dealers.
 Rule G-17 requires each dealer, in the conduct of its municipal securities business, to deal fairly with all persons and prohibits the dealer from engaging in any deceptive, dishonest or unfair practice.
