The Securities and Exchange Commission today announced charges against Concord Management LLC of Tarrytown, New York, and its owner and principal, Michael Matlin, for operating as unregistered investment advisers to their only client—a wealthy former Russian official widely regarded as having political connections to the Russian Federation. According to the SEC’s complaint, Matlin founded Concord in 1999 to provide investment advice for compensation and to supervise and manage the client’s investments in United States-based private funds.
