Fair Values of Financial Instruments [Abstract]  
Fair Values of Financial Instruments
(19)Fair Values of Financial Instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments which are not carried at fair value on the consolidated balance sheets:

            Cash & Cash Equivalents

The carrying amounts reported in the consolidated balance sheets for cash and short-term instruments are a reasonable estimate of fair value.  The carrying amount is a reasonable estimate of fair value because of the relatively short term between the origination of the instrument and its expected realization.  Therefore, the Company believes the measurement of fair value of cash & cash equivalents is derived from Level 1 inputs.

Certificates of Deposit

The Company measures the fair value of Certificates of deposit using level 2 inputs.  The fair values of Certificates of deposit were derived by discounting their future expected cash flows back to their present values based upon a constant maturity curve. The constant maturity curve is based on similar instruments, taking into account factors such as instrument type, coupon type, currency, issuer, sector, country of issuer, credit rating, and prevailing market conditions. The Company believes these inputs fall under Level 2 of the fair value hierarchy.

            Other Equity Securities

The carrying amounts reported in the consolidated balance sheets approximate fair value as the shares can only be redeemed by the issuing institution.  The Company believes the measurement of the fair value of other equity securities is derived from Level 2 inputs.

            Loans Receivable

For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.  The fair values for other loans (e.g., commercial real estate and rental property mortgage loans, commercial and industrial loans, and agricultural loans) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  The allowance for loan losses is considered to be a reasonable estimate of loan discount due to credit risks.  Given that there are loans with specific terms that are not readily available, the Company believes the fair value of loans receivable is derived from Level 3 inputs.

            Loans Held-for-Sale

For loans held for sale, the fair value is based on what secondary markets are currently offering for portfolios with similar characteristics.  See Note 8, Fair Value Measurement.

            Interest Receivable and Payable

The carrying amount of interest receivable and payable approximates its fair value.  The Company believes the measurement of the fair value of interest receivable and payable is derived from Level 2 inputs.

            Mortgage Servicing Rights

The Company uses quoted market prices when available.  Subsequent fair value measurements are determined using a discounted cash flow model.  In order to determine the fair value of the MSR, the present value of expected future cash flows is estimated.  Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income.  This model is periodically validated by an independent external model validation group.  The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available.  

            Deposit Liabilities

The Company measures fair value of deposits using Level 2 and Level 3 inputs.  The fair value of deposits were derived by discounting their expected future cash flows back to their present values based on the FHLB yield curve, and their expected decay rates for non-maturing deposits.  The Company is able to obtain FHLB yield curve rates as of the measurement date, and believes these inputs fall under Level 2 of the fair value hierarchy.  Decay rates were developed through internal analysis, and are supported by recent years of the Bank's transaction history.  The inputs used by the Company to derive the decay rate assumptions are unobservable inputs, and therefore fall under Level 3 of the fair value hierarchy.

            Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument.  These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument.  Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on-and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments.  Other significant assets and liabilities that are not considered financial assets or liabilities include deferred tax liabilities and premises and equipment.  In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in many of the estimates.
