[1] The property loans are held in trust in connection with TOB trust financings (Note 16). The property loans and associated GILs are on parity and share a first mortgage lien position on all real and personal property associated with the underlying property. Affiliates of the borrowers have guaranteed limited-to-full payment of principal and accrued interest on the property loans. The borrowers may elect to extend the maturity dates for periods ranging between six and twelve months upon meeting certain conditions, which may include payment of a non-refundable extension fee. The variable index interest rate components are typically subject to floors that range from 0% to 0.50%
