Debt marked at fair value is the Company's estimate of the "fair value" of its senior unsecured notes.  The current estimated fair value of the Company's senior unsecured notes is based on a discount rate calculated using the redemption yield of the relevant existing UK Gilt plus a credit spread determined by the difference in redemption yields between the ICE BofAML 10-15 Year A Sterling Non-Gilt Index and the ICE BofAML 10-15 Year UK Gilt Index. The discount rate is calculated and updated at each month-end and applied daily to determine the Company's published fair value NAVs.
