This case considers the unusual terms under which Rhone-Poulenc, the large French chemicals producer, acquired the U.S.-based Rorer Group, Inc., in August 1990. Set a year later, in August 1991, the case reviews the terms of the merger and the experience of the new entity in its first year, and invites the student to evaluate the “contingent value right” (CVR) issued by Rhone-Poulenc in the merger.
