Common Errors When Applying Discounts and Premiums in Business Valuations

In family law property settlements, business valuations often play a major role in determining how assets are divided. A key part of these valuations involves applying discounts and premiums to reflect ownership rights, control, and marketability.

When these adjustments are applied incorrectly, the value of a business interest can be significantly distorted. Even small mistakes can lead to valuations that are misleading, difficult to defend, or challenged during negotiations or in court.

Understanding the most common errors helps lawyers, business owners, and separating couples recognise when a valuation may require closer scrutiny.

Using Acquisition Premiums as Control Premiums

One common mistake is relying on acquisition premiums from takeover transactions to estimate control premiums.

Many corporate acquisitions involve synergies such as cost savings, strategic advantages, or operational improvements that are unique to the buyer. These synergies increase the price paid but may not reflect the stand alone value of the business being valued.

If those synergies are included in a valuation, the control premium may be overstated.

Assuming Discounted Cash Flow Always Produces a Minority Value

Another frequent misunderstanding involves the discounted cash flow (DCF) method.

Some analysts assume that a DCF valuation automatically produces a minority value and therefore always requires a control premium. In reality, the outcome depends on the assumptions used in the analysis, particularly whether the projected cash flows reflect minority or controlling ownership.

Applying a control premium without examining the underlying assumptions can result in double counting.

Assuming Public Market Prices Always Represent Minority Interests

Valuers sometimes assume that share prices from public companies represent minority values.

However, public market prices may already reflect expectations of acquisitions or control transactions. In these situations, applying a control premium on top of those prices can significantly overstate the value of a business.

Valuing Assets Instead of Ownership Interests

Another common error is focusing on the value of the underlying assets rather than the ownership interest being valued.

Owning shares in a company is not the same as owning the assets directly. Shareholders often cannot sell or control those assets individually. Because of this limitation, a minority ownership interest is often worth less than a proportional share of the asset value.

Relying on Average Discounts Without Analysis

Empirical studies often show a wide range of discounts and premiums.

Despite this, some valuation reports simply apply an average figure without analysing whether the subject business is comparable to the companies in the study. This approach can produce unreliable results if the specific circumstances of the business are not considered.

Applying Adjustments to the Entire Capital Structure

Another mistake occurs when discounts or premiums are applied to the entire capital structure instead of just the equity interest.

Most empirical evidence relates to equity ownership. Applying adjustments to debt and other capital components can inflate the dollar value of the discount or premium and produce inaccurate valuation results.
