Net Asset Value (NAV) per Share is calculated as available shareholders’ funds divided by the number of shares in issue, with shareholders’ funds taken to be the net value of all the company’s assets after deducting liabilities. The NAV figure above is based on the fair/market value of the company’s long-term debt and preference shares (known as debt at market value). This allows for the valuation of long-term debt and preference shares at fair value or current market price, rather than at final repayment value (known as debt at par).
