The Company has certain loans for which repayment is dependent upon the operation or sale of collateral, as the borrower is experiencing financial difficulty. The underlying collateral can vary based upon the type of loan. The following provides more detail about the types of collateral that secure collateral dependent loans:

•Commercial real estate loans can be secured by either owner occupied commercial real estate or non-owner occupied investment commercial real estate. Typically, owner occupied commercial real estate loans are secured by office buildings, warehouses, manufacturing facilities and other commercial and industrial properties occupied by operating companies. Non-owner occupied commercial real estate loans are generally secured by office buildings and complexes, retail facilities, multifamily complexes, land under development, industrial properties, as well as other commercial or industrial real estate.

•Residential real estate loans are typically secured by first mortgages, and in some cases could be secured by a second mortgage.

•Home equity lines of credit are generally secured by second mortgages on residential real estate property.

•Consumer loans are generally secured by automobiles, motorcycles, recreational vehicles and other personal property. Some consumer loans are unsecured and have no underlying collateral.

The following table details the amortized cost of collateral dependent loans:
