According to FINRA, Christopher Gerard Perillo (CRD #7589151) of Merrick, New York, was suspended for 18 months and assessed a deferred fine of $5,000 for possessing and having access to unauthorized study materials while taking the Municipal Securities Rulemaking Board (MSRB) Series 52 qualification examination. The action, effective March 28, 2024, found that during a lengthy unscheduled break from the exam, Perillo had access to study materials in the test center restroom. Prior to taking the exam, Perillo had attested to abide by MSRB Rule G-3(f) and the examination Rules of Conduct, which prohibit candidates from accessing any unauthorized materials during the examination period, including during breaks. The Series 52 examination, formally known as the Municipal Securities Representative Qualification Examination, tests the knowledge required of professionals who engage in municipal securities activities. Municipal securities, including bonds issued by state and local governments, are held by millions of individual investors, and it is essential that the professionals who sell and advise on these products demonstrate genuine competency. The examination process serves as a gatekeeper to ensure that only qualified individuals are permitted to transact in municipal securities on behalf of investors. Having unauthorized study materials accessible during an exam break undermines the integrity of this qualification process. Even if Perillo did not actively consult the materials, their mere presence and accessibility during the examination period constitutes a violation of the rules to which he attested. FINRA and the MSRB take examination integrity extremely seriously because the qualification process is the primary mechanism for ensuring baseline professional competency in the securities industry. Perillo's suspension is effective from April 1, 2024, through September 30, 2025. This case demonstrates that exam integrity rules apply not only during active testing but throughout the entire examination period, including breaks. Aspiring municipal securities professionals should take great care to ensure they have no access to any unauthorized materials at any point during the testing process.
