(1) No person using the mails, or any means or instrumentality of interstate commerce, in the exercise of investment discretion with respect to an account shall be deemed to have acted unlawfully or to have breached a fiduciary duty under State or Federal law unless expressly provided to the contrary by a law enacted by the Congress or any State subsequent to June 4, 1975, solely by reason of his having caused the account to pay a member of an exchange, broker, or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission another member of an exchange, broker, or dealer would have charged for effecting that transaction, if such person determined in good faith that such amount of commission was reasonable in relation to the value of the brokerage and research services provided by such member, broker, or dealer, viewed in terms of either that particular transaction or his overall responsibilities with respect to the accounts as to which he exercises investment discretion. This subsection is exclusive and plenary insofar as conduct is covered by the foregoing, unless otherwise expressly provided by contract: Provided, however, That nothing in this subsection shall be construed to impair or limit the power of the Commission under any other provision of this title or otherwise.
(2) A person exercising investment discretion with respect to an account shall make such disclosure of his policies and practices with respect to commissions that will be paid for effecting securities transactions, at such times and in such manner, as the appropriate regulatory agency, by rule, may prescribe as necessary or appropriate in the public interest or for the protection of investors.
(3) For purposes of this subsection a person provides brokerage and research services insofar as he–
(A) furnishes advice, either directly or through publications or writings, as to the value of securities, the advisability of investing in, purchasing, or selling securities, and the availability of securities or purchasers or sellers of securities;
(B) furnishes analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy, and the performance of accounts; or
(C) effects securities transactions and performs functions incidental thereto (such as clearance, settlement, and custody) or required in connection therewith by rules of the Commission or a self-regulatory organization of which such person is a member or person associated with a member or in which such person is a participant.
(4) The provisions of this subsection shall not apply with regard to securities that are security futures products.
