Notional Market Valuation Concept in Business Valuation
In business valuation, notional market valuation refers to determining the value of a business or asset without an open market transaction. When valuation is required outside real-world negotiations, valuers assess the notional market value—an estimated value based on valuation principles, ethics, and professional judgment.
Notional Market vs. Open Market: Key Differences
The notional market describes situations where a fair market value, fair value, or other defined value is determined without an active, negotiated market. In contrast, an open market involves actual transactions, with a buyer and seller negotiating terms and price at arm’s length.
In situations requiring a notional valuation, value is based on hypothetical conditions, assuming both the buyer and seller have reasonable knowledge of relevant facts, with neither compelled to transact. While fair market value is the term most commonly used in a notional market context, the specific value term may vary depending on legal or contractual requirements.

What is Fair Market Value?
Fair market value is defined as:
“The highest price, expressed in terms of cash equivalents, at which property would change hands between a hypothetical willing and able buyer and a hypothetical willing and able seller, acting at arm’s length in an open and unrestricted market, with neither party under compulsion to buy or sell and both having reasonable knowledge of relevant facts.”
This valuation term is typically applied in a notional market setting.
Why Notional Market Value May Differ from Transaction Price
The value determined in a notional market context often differs from an actual transaction price, as it excludes unique motivations of specific buyers or sellers. For instance, a buyer interested in synergies or strategic advantages may pay a premium above fair market value. However, without a special purchaser or identifiable factors warranting a premium, the notional market value provides a reliable baseline.
When is Notional Market Valuation Applied?
Notional market valuations are commonly used in situations where open market transactions are not feasible, and company shares are not publicly traded on the stock exchange. These scenarios include:
- Non-Arm’s Length Transactions: Transfers within families or internal reorganizations may require valuations for tax compliance.
- Family and Divorce Law: Determining business value for equitable distribution.
- Shareholder Agreements: Establishing buy-sell agreements based on predetermined valuation terms.
- Employee Stock Ownership Plans (ESOPs): Setting fair share prices for employee stock ownership.
- Minority Shareholder Rights: Supporting shareholder appraisal and oppression remedies.
- Commercial Litigation and Business Interruption Claims: Assessing damages for insurance or legal claims.
In these cases, a notional market valuation provides a fair, defensible value based on business valuation principles while considering hypothetical market conditions rather than actual buyer-seller negotiations.
Why Notional Market Valuation Matters in Business Valuation
When valuing a business in a notional market context, adherence to established business valuation principles is essential to ensure consistency, reasonableness, and credibility in the value conclusion. Although fair market value is commonly used, valuers must understand the valuation’s intended purpose, as other value terms (such as “fair value”) may apply based on specific legal or contractual requirements.
The credibility of a notional market valuation also rests on the appropriateness of valuation methodologies, the consistency of underlying assumptions, and the professional judgment of the valuer.
