In the United States, in the context of stockholderlawsuits, typically relating to the sale or merger of a public company, the Delaware Court of Chancery has required sufficient disclosures be made to a board of directors and shareholders to “provide a balanced, truthful account of all matters” and said “When a document ventures into certain subjects, it must do so in a manner that is materially complete and unbiased by the omission of material facts.” In a Memorandum Opinion in the CheckFree/Fiserv merger Chancellor Chandlerunderlined that the earlier In re Pure Resources Court had established the proper frame of analysis for disclosure of financial data: “tockholders are entitled to a fair summary of the substantive work performed by the investment bankers upon whose advice the recommendations of their board as to how to vote on a merger or tender rely.” According to the certification hypothesis fairness opinions may also serve the interest of the shareholders by mitigating informational asymmetries in corporate transactions.
