[1] Based on appraised values and liens due other lenders at loan closing. The loan-to-value computation does not take into account subsequent increases or decreases in security property values following the loan closing nor does it include decreases or increases of the amount owing on senior liens to other lenders by payments or interest accruals, if any. Property values likely have changed, particularly over the last four years, and the portfolio's current loan to value ratio likely is higher than this historical ratio.
