Charlie Mancini, CFA, is the Managing Director of VES Financial (VES), a large US—based mutual fund organization. Mancini has been under pressure recently to increase revenues. In order to secure business from a large hedge fund manager based in Asia, Mancini recently approved unusual terms for the fund’s client agreement. To allow for time zone differences, the agreement allows the hedge fund to trade in all of VES’s mutual funds six hours after the close of US market. According to the Standards of Practice Handbook, did Mancini violate any CFA Institute Standards of Professional Conduct()

A. No.

B. Yes, because he failed to inform his other clients of the unusual terms under the new client agreement, thus not treating clients equally.

C. Yes, because he failed to review regulations on late-trading and did not consult with VES’s compliance director to determine if late-trading was acceptable.
