Fair Value Measurements [Abstract] |
Fair Value Measurements | Fair Value Measurements U.S. GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. U.S. GAAP also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active exchange markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The following is a description of the valuation methodologies used to measure and report fair value of financial assets and liabilities on a recurring or nonrecurring basis: Measured on a Recurring Basis Securities Securities available for sale are recorded at fair value on a recurring basis. Fair value is determined with quoted prices for similar assets or liabilities, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data (Level 2). The following table presents the balance of assets measured at fair value on a recurring basis at September 30, 2011:

There were no transfers between, into and/or out of Levels 1, 2 or 3 during the quarter ended September 30, 2011. Measured on a Nonrecurring Basis Impaired Loans & Real Estate Held for Sale From time to time, and on a nonrecurring basis, fair value adjustments to collateral dependent loans and real estate held for sale are recorded to reflect write-downs of principal balances based on the current appraised or estimated value of the collateral. Real estate held for sale consists principally of properties acquired through foreclosure. The following table presents the aggregated balance of assets measured at estimated fair value on a nonrecurring basis for the year ended September 30, 2011, and the total losses resulting from those fair value adjustments for the quarter and year ended September 30, 2011. The following estimated fair values are shown gross of estimated selling costs:
