The Commission may promulgate rules to provide that the standard of conduct for all brokers, dealers, and investment advisers, when providing personalized investment advice about securities to retail customers (and such other customers as the Commission may by rule provide), shall be to act in the best interest of the customer without regard to the financial or other interest of the broker, dealer, or investment adviser providing the advice. In accordance with such rules, any material conflicts of interest shall be disclosed and may be consented to by the customer. Such rules shall provide that such standard of conduct shall be no less stringent than the standard applicable to investment advisers under section 80b–6(1) and (2) of this title when providing personalized investment advice about securities, except the Commission shall not ascribe a meaning to the term “customer” that would include an investor in a private fund managed by an investment adviser, where such private fund has entered into an advisory contract with such adviser. The receipt of compensation based on commission or fees shall not, in and of itself, be considered a violation of such standard applied to a broker, dealer, or investment adviser.
