Foreclosed Assets [Text Block]	NOTE 5 Real estate that is acquired through foreclosure or a deed in lieu of foreclosure is classified as other real estate owned ("OREO") until it is sold. When real estate is acquired through foreclosure or by deed in lieu of foreclosure, it is recorded at its fair value, less the estimated costs of disposal. If the fair value of the property is less than the loan balance, the difference is charged against the allowance for credit losses. Assets are classified as foreclosed when physical possession of the collateral is taken regardless of whether foreclosure proceedings have taken place. Other foreclosed assets received in satisfaction of borrowers’ debts are initially recorded at fair value of the asset less estimated costs to sell.
