Much deserved attention has been paid to the first finding of a “material adverse change” (MAC) by a Delaware court in the recent Akorn decision. Of perhaps equal practical importance to dealmakers is the court’s guidance on a question that has long occupied draftspersons—whether or not there is, and the extent of, any legal difference between the many shades of qualifiers used in deal agreements on two key terms: materiality modifiers and efforts covenants. Building on earlier Delaware decisions, the court reached a clear split decision on this question.
