摘要:The ability to protect mergers is important to both targets and acquirors. A series of recent Chancery Court decisions, however, challenges the validity of deal protection provisions in merger agreements and threatens the stability of Delaware's established change of control paradigm. This article argues that last period concerns animate the Chancery Court's decisions and finds, in the last period problem, a theoretical principle capable of harmonizing these decisions with existing jurisprudence and providing a coherent approach to the practical problems raised by deal protection provisions.
