Why does Fairness Opinion matter?
A board approving a sale, especially one where insiders such as a founder-CEO have a personal stake in the deal closing, faces real legal exposure if disappointed shareholders later claim the board breached its fiduciary duty by approving an unfair price. An independent fairness opinion does not guarantee the deal is optimal, but it gives the board a documented, arm's-length basis for its decision that materially reduces that legal risk, which is why boards commission one even when they are already confident in the price.
What does Fairness Opinion look like in practice?
Suppose a board is evaluating an acquisition offer where the CEO, who also sits on the board, would receive a large personal retention package as part of the deal, a clear potential conflict. Commissioning an independent fairness opinion from a firm with no stake in whether the deal closes gives the rest of the board, and later, shareholders reviewing the decision, documented evidence that the price was assessed as fair by someone without the CEO's personal incentive to see the deal through.
What are the common mistakes with Fairness Opinion?
- Skipping a fairness opinion on a deal with insider conflicts to save the fee, leaving the board more exposed if a disappointed shareholder later challenges the process.
- Treating the fairness opinion as a green light on deal quality rather than what it actually is, a defense of process, focused narrowly on whether the price falls within a reasonable range.
- Using an advisor with an existing relationship to the buyer, or a fee contingent on the deal closing, which undermines the independence the opinion is meant to demonstrate.
- Assuming a fairness opinion is legally required for every sale. It is a risk-management choice for the board, and its necessity scales with deal size and conflict exposure.
Where the term comes from
Fairness opinions became standard because a board did not get one. In Smith v. Van Gorkom (1985) the Delaware Supreme Court held that Trans Union's directors had breached their duty of care in approving a $690 million buyout after a two-hour meeting, with no valuation study and no fairness opinion. The decision made obtaining one a routine part of board process rather than a legal requirement, which it still is not.
