What is fair market value and how is it determined for a private business?
Fair market value is the highest price available in an open and unrestricted market between informed and prudent parties acting at arm's length under no compulsion to transact. This definition, established by the Canada Revenue Agency, assumes both buyer and seller are knowledgeable about the business and the transaction, have access to relevant information, and are not under duress to complete the deal.
What Fair Market Value Means
Fair market value (FMV) represents what a hypothetical willing buyer would pay a hypothetical willing seller when both parties are acting rationally, with full information, and without pressure to close the deal. The standard assumes a going concern — a business that will continue operating indefinitely — rather than a distressed sale or asset liquidation.
This is not the price a specific buyer might pay based on strategic synergies or emotional attachment. It is the price the broader market would establish for the business under normal conditions. Fair market value is the required standard for tax-related valuations in Canada, including estate planning, shareholder disputes, and capital gains calculations.
Why Fair Market Value Is the Standard for Most Transactions
Fair market value serves as the baseline for most business valuations because it provides an objective, defensible benchmark. Tax authorities, courts, and financial institutions rely on FMV to ensure valuations are grounded in market reality rather than the interests of one party.
Investment value — also called strategic value — typically exceeds fair market value because it reflects synergies and strategic benefits specific to a particular buyer. A competitor acquiring a business to eliminate redundant overhead might pay more than fair market value. An individual buyer purchasing the same business to operate independently would likely pay closer to FMV. The difference between these two prices is the strategic premium, which is not reflected in fair market value.
The Three Main Valuation Approaches Used to Determine FMV
Valuators use three recognized approaches to estimate fair market value: the income approach, the market approach, and the asset-based approach. Each approach examines the business from a different angle. A formal valuation typically applies all three methods and reconciles the results to arrive at a final FMV conclusion.
Income-Based Approach: Discounted Cash Flow and Capitalization
The income approach estimates fair market value by converting expected future cash flows into present value using a discount rate that reflects risk. This approach is grounded in the principle that a business is worth the present value of the cash it will generate for its owners.
The discounted cash flow (DCF) method projects cash flows over a finite period — typically 5 to 10 years — and adds a terminal value representing the business value beyond the projection period. The discount rate applied in DCF valuations reflects the weighted average cost of capital (WACC) for companies with debt, or the cost of equity for all-equity capital structures. Company-specific risk premiums are added to the discount rate to reflect factors such as customer concentration, key person dependency, or operational risks not captured in industry benchmarks.
The capitalization of earnings method is commonly used for stable, mature businesses with predictable cash flows. This method applies a capitalization rate to a single normalized earnings figure, producing a value estimate without multi-year projections. Normalized earnings adjustments — add-backs for owner discretionary expenses, non-recurring items, and excess compensation — are standard practice in determining the earnings base used in this method.
Market-Based Approach: Comparable Sales and Transaction Multiples
The market approach determines fair market value by comparing the subject business to similar businesses that have been sold, using transaction multiples such as EBITDA multiples or revenue multiples.
Private company transaction multiples typically range from 2.0x to 4.0x EBITDA for Main Street businesses under $5 million in enterprise value. Lower middle market companies ($5M–$50M enterprise value) typically transact at 4.0x to 7.0x EBITDA, depending on industry sector, growth profile, and market conditions.
The market approach requires access to reliable transaction data. Public databases like BizBuySell and GF Data provide comparable sale information, though the quality and comparability of data varies. Valuators adjust multiples to account for differences in size, profitability, growth rate, and risk profile between the subject business and the comparables.
Asset-Based Approach: Net Asset Value
The asset-based approach values a business by calculating net asset value: the fair market value of all assets minus liabilities, with adjustments to reflect replacement cost or liquidation scenarios.
Asset-based approaches are most relevant for holding companies, real estate-intensive businesses, or companies with minimal ongoing operations where asset values drive enterprise value. For operating businesses with established cash flow, valuators typically weight the income and market approaches more heavily than the asset approach.
Fair market value assumes a going concern, while liquidation value assumes orderly or forced sale of assets. Liquidation value represents the amount that could be realized if assets were sold separately under distressed conditions, and is typically significantly lower than fair market value for an ongoing business.
How Valuators Weight the Three Approaches
A Chartered Business Valuator (CBV) will typically reconcile values derived from multiple approaches to arrive at a final fair market value conclusion, explaining the weighting rationale in the valuation report. The weighting depends on the reliability of the data available, the nature of the business, and the purpose of the valuation.
For a profitable manufacturing business with steady cash flows and comparable transaction data, a valuator might weight the income approach at 50%, the market approach at 40%, and the asset approach at 10%. For a holding company with primarily real estate assets and no operating income, the asset approach might receive 80% or more of the weighting.
When Fair Market Value Differs from Other Standards of Value
Fair market value is not the only standard of value used in business valuations. Different legal and transaction contexts require different valuation standards.
Notional market value, used in some family law contexts, differs from fair market value by hypothetically assuming a willing buyer exists when one may not exist in reality. This distinction can produce a higher valuation than fair market value for illiquid or unmarketable interests.
Minority discounts (typically 15–30%) may reduce fair market value when valuing non-controlling interests that lack the ability to direct business decisions or force liquidity. Marketability discounts (typically 20–40% for restricted shares) reflect the lack of ready market and restrictions on transferability for private company shares. These discounts are applied to arrive at the fair market value of a specific interest, distinct from the fair market value of the business as a whole.
