Fairness Opinion
A fairness opinion is a written assessment by an independent financial advisor — typically an investment bank — stating whether the consideration to be paid in a merger, acquisition, or other significant transaction is fair from a financial point of view to the shareholders receiving it.
Boards of directors overseeing a significant corporate transaction have a fiduciary duty to act in the best interests of shareholders. A fairness opinion helps boards discharge that duty by providing an independent valuation analysis and a formal written conclusion that the transaction consideration falls within a range of fairness. While the opinion is addressed to the board, it also provides shareholders with assurance that an independent expert has evaluated the deal economics.
Fairness opinions are prepared by investment banks and other financial advisors using standard valuation methodologies. The advisor typically runs a discounted cash flow analysis of the target company, analyzes comparable publicly traded companies to develop a trading multiple range, reviews precedent acquisition transactions for relevant purchase price multiples, and may consider a leveraged buyout analysis to assess the price a financial buyer might pay. The opinion is based on information provided by the company, publicly available data, and the advisor's professional judgment, and is typically qualified with significant assumptions and limitations.
The fairness opinion letter itself is succinct — often just a few paragraphs — but is backed by an extensive financial analysis delivered verbally to the board in a presentation called the 'board book.' The board is expected to review and discuss the analysis in detail before voting on the transaction. The fairness opinion and related materials are included in the proxy statement or transaction disclosure document filed with the SEC, allowing shareholders to review the analysis before voting.
Fairness opinions have attracted criticism over the years for their tendency to support whatever transaction the client board has already decided to pursue. Because investment banks are paid their full advisory fee only if the transaction closes, critics argue there is a structural incentive to find transactions fair. Courts have generally not treated the existence of a fairness opinion as automatically establishing that a board fulfilled its duties — the board must actually review and understand the analysis, and the opinion must be from an appropriately qualified and independent advisor.
Special committees of independent directors are typically required to obtain their own independent fairness opinion when a transaction involves a controlling shareholder, management participation, or other conflicts of interest, ensuring that the opinion is not tainted by the interests of the conflicted parties.
