Answer: Fair value of unquoted company can be calculated or arrived at by getting the net value of assets less net value of liabilities.
Explanation: Generally, fair value of mostly quoted shares is arrived at by comparing the p/e ratios of quoted companies in the same or similar industry e.g Banking, ICT etc. and we then pick an average figure in relation to the chosen industry.
However, for an unquoted company which price is not easily available or ascertained, we can arrive at a fair share value by netting off value of assets and liabilities. This gives a hypothetical value that may be used to pay up a dissenting shareholder.
