It is well-settled under Delaware law that in a merger a stockholder loses standing to assert a purely derivative claim. That claim passes instead to the acquiring company. As an asset of a Delaware company, derivative claims should be valued in a merger transaction. Directors of a selling company, however, who fail to value derivative claims and who also bargain for their extinguishment following the merger are at risk of being found to have breached their fiduciary duty.

The Court of Chancery’s recent decision in In re Riverstone National Stockholder Litigation, C.A. No. 9796-VCG (Del. Ch. July 28), instructs that a complaint asserting that directors, who faced personal liability on known derivative claims, both attributed no value to the derivative claims and bargained in a merger transaction that the buyer would not assert them, is sufficient to avoid dismissal based on the general rule of post-merger loss of standing, if the stockholder pleads the claims as part of a direct attack on the merger.
