Cleary Gottlieb’s M&A blog’s recent post, Negotiating Appraisal Conditions in Public M&A Transactions, analyzes attempts — sometimes successful — by acquirors of Delaware public companies to include a closing condition in the merger agreement that would relieve the buyer from closing if a certain triggering percentage of appraisal rights are exercised.  Their post discusses the negotiating and drafting of such thresholds and related provisions.
