The percentage is only the starting point

Identify the shares and the question being asked

Start with the company, class of shares, number held and valuation date. A 20% economic interest does not necessarily carry 20% of every decision-making right. Different classes, preference rights, veto arrangements or distribution rules can change the analysis.

An agreed exit formula may also answer a different question from a hypothetical market sale. Provide the constitution, shareholder agreement and relevant instructions before work begins. Where the wording is disputed, obtain legal clarification; the valuation should not silently choose an interpretation that determines someone’s rights.

Read the rights before applying a percentage

There is no universal minority discount

The effect of limited control or marketability depends on the specific interest and valuation basis. It should not be reduced to a standard percentage copied from another matter. Some instructions or agreements may require a proportionate value or prescribe how particular adjustments are treated.

If an adjustment is appropriate, explain the rights and evidence it responds to and avoid counting the same risk more than once. A risk already reflected in cash flows, distributions or another part of the valuation may not warrant a second overlapping reduction.

Separate the arithmetic from the conclusion

Suppose the total equity value is hypothetically $1 million and an owner holds 20% of ordinary shares. The simple pro-rata amount is $200,000. That arithmetic does not determine whether $200,000 is the required answer under the relevant purpose, share rights or exit agreement.

The settlement may also include repayment of a shareholder loan, a release of guarantees or deferred payments. Record those separately. Combining everything into a single “share value” can obscure which assumptions affect the valuation and which are commercial or legal terms of the exit.

• Confirm the subject interest and valuation date.
• Provide the full agreement, including amendments.
• Identify any disputed instructions before commissioning work.
• Keep share value and other settlement amounts distinct.
