A failure to disclose this information is a violation of the anti-touting provisions of the federal securities laws. Persons making these endorsements may also be liable for potential violations of the anti-fraud provisions of the federal securities laws, for participating in an unregistered offer and sale of securities, and for acting as unregistered brokers.”
