Statutory appraisal remedies allow stockholders who believe they have received inadequate consideration in certain transactions, such as mergers or consolidations, to obtain a judicial determination of the fair value of their shares. Over the years, courts, litigants, and experts alike have grappled with how to make an appropriate fair value determination. To marshal the evidence necessary to most favorably present their case, it is vital for counsel involved in appraisal proceedings to understand the relevant statutory requirements and stay up to date on the shifting case law, including the valuation approach courts are likely to prefer in a given situation.
