(1)Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

(a)The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.
(b)Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.
(c)Federal Home Loan Bank stock has no quoted market value and is carried at cost; therefore the carrying amount approximates fair value.
(d)Cash surrender value of life insurance policies is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.
(e)Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.
(f)Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.
(g)Fair value was determined based upon market prices of securities with similar terms and maturities.
