DUF Duff & Phelps Corp. Class A

Brower Piven, A Professional Corporation announces that a class action lawsuit has been commenced in the Delaware Court of Chancery on behalf of all shareholders of Duff & Phelps ("Duff & Phelps" or the "Company") (NYSE:DUF).

According to the complaint, under the terms of the proposed transaction, The Carlyle Group, Stone Point Capital, LLC, Pictet & Cie and Edmond de Rothschild Group would acquire the outstanding shares of Duff & Phelps it does not currently own for a value of $15.55 per share. The transaction has a total approximate value of $665.5 million. The claims concern, among other things, whether the proposed consideration to be paid to Duff & Phelps shareholders is unfair, inadequate, and substantially below the fair or inherent value of Duff & Phelps.
