These have the impact of inflating both yield and the charge-off rate of the securitised portfolio relative to the bank portfolio. The bonds were issued on 15 December 2005; expense rate and excess spread for December have therefore been omitted as not meaningful. - ---------------------------------------------------------------------------------------------------------------------------------- Delinquencies (loans which are 30 days or more past due) - ---------------------------------------------------------------------------------------------------------------------------------- (% Pool) ----------------------------------------------------------------------------- Month end 30-59 days 60-89 days 90-179 days 180+ days Total - --------- ---------- ---------- ----------- --------- ----- 28 Feb 2006 1.32% 0.97% 2.32% 3.24% 7.85% 31 Jan 2006 1.27% 0.93% 2.27% 3.11% 7.58% 31 Dec 2005 1.17% 0.92% 2.18% 2.99% 7.26% - ---------------------------------------------------------------------------------------------------------------------------------- Payment Rate - -------------------------------------------------------------------------------- Payments Pool balance ------------------------------ ------------ Month End Total ((pound)000) Rate (%) (pound)000 28 Feb 2006 1,071,000 20.30% 5,212,805 31 Jan 2006 1,239,175 23.00% 5,275,021 31 Dec 2005 1,200,030 22.33% 5,388,175 - -------------------------------------------------------------------------------- - --------------------------------------------------------------- Average Actual Balance: (pound) 1,115 Number of Accounts: 4,677,142 - --------------------------------------------------------------- IN WITNESS WHEREOF, the undersigned has duly executed this Monthly Servicer's Report as of the 15th day of March, 2006.
