Appraisal rights, also called dissent rights or buy-out rights, among other variants,[1][2] are the rights of shareholders to receive a court-supervised valuation of their shares when certain major changes, such as an acquisition of the company, are contemplated. Shareholders who do not support the transaction are entitled to receive the value of their shares in cash, as determined by the court. Appraisal rights are available in jurisdictions including Canada, the United Kingdom, and the United States.
