[1] The method of valuation approach for the loans evaluated for an allowance for credit losses on an individual loan basis and also for other real estate owned was the market approach based upon appraisals of the underlying collateral by external appraisers, reduced by 7% to 10% for estimated selling costs. Intangible assets are valued based upon internal analyses.
