This Article articulates a legal reform that is designed to rein in the num
ber of value-decreasing stock-for-stock mega-mergers--the signature transac
tion of the 1990s and the beginning years of the new millennium-by causing
board members to question more critically a mega-merger proposal when they
are asked to approve it and even to continue to reevaluate their approval o
f a merger until its closing. The Article first describes the current merge
r wave and highlights reports of emerging problems in mega-mergers and the
relevant economic data indicating that a majority of the transactions are v
alue-decreasing for shareholders both in. the short and long term. It next
examines why these transactions are occurring and why they have been little
criticized, focusing on their economic and business justifications, the re
cognizable psychological, tendencies (exacerbated in, todays merger mate) a
ffecting chief executives, board members and investors and motivating them
to propose and approve the transactions, and the journalistic celebration o
f land a general political silence on) the mega-mergers. The Article then a
nalyzes the legal foundations of the mega-mergers and observes that merger
jurisprudence developing from cases involving hostile takeovers encouraged
(i) management to engage in (and boards to approve with little court review
) stock-for-stock mega-mergers and (ii) the corporate law bar to reinforce
contractual provisions in merger agreements intended to "tie the hands" of
boards that enter into the mergers. Finally, the Article proposes a new int
ermediate standard of court review for board decisions approving stock-for-
stock mega-mergers, which should produce a new standard of board conduct in
these transactions, addresses several possible criticisms of the standard,
and advocates additional nonlegal and legal reforms that would make the st
andard more effective.
