Estimated Fair Value of Financial Instruments

(12) Estimated Fair Value of Financial Instruments

The Corporation discloses estimated fair values for its financial instruments. Fair value estimates, methods and assumptions are set forth below for the Corporation’s financial instruments.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

•	The carrying value of cash and due from banks, Federal funds sold, short-term investments, interest-bearing deposits in other banks and accrued interest receivable and other financial assets is a reasonable estimate of fair value due to the short-term nature of the asset.
•	The fair value of investment securities is based on quoted market prices, where available. If quoted market prices are not available, fair value is estimated using the quoted market prices of comparable instruments.
•	For variable rate loans with interest rates that may be adjusted on a quarterly, or more frequent basis, the carrying amount is a reasonable estimate of fair value. The fair value of other types of loans is estimated by discounting 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.
•	The carrying value approximates the fair value for bank owned life insurance.
•	The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, savings, money market, checking and interest-bearing checking, is equal to the amount payable on demand as of the balance sheet date, for each year presented. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. For variable rate certificates of deposit, the carrying amount is a reasonable estimate of fair value.
•	Securities sold under repurchase agreements, other short-term borrowings, accrued interest payable and other financial liabilities approximate fair value due to the short-term nature of the liability.
•	The fair value of Federal Home Loan Bank advances is estimated by discounting future cash flows using current FHLB rates for the remaining term to maturity.
•	The fair value of junior subordinated debentures is based on the discounted value of contractual cash flows using rates currently offered for similar maturities.
•	The fair value of commitments to extend credit approximates the fees charged to make these commitments; since rates and fees of the commitment contracts approximates those currently charged to originate similar commitments. The carrying amount and fair value of off-balance sheet instruments is not significant as of June 30, 2011 and December 31, 2010.
	Limitations

Estimates of fair value are made at a specific point in time, based on relevant market information and information about the financial instrument. 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.

Estimates of fair value 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. For example, the Corporation has a substantial Investment and Trust Services Division that contributes net fee income annually. The Investment and Trust Services Division is not considered a financial instrument and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities that are not considered financial instruments include property, plant and equipment, goodwill and deferred tax liabilities. In addition, it is not practicable for the Corporation to estimate the tax ramifications related to the realization of the unrealized gains and losses and they have not been reflected in any of the estimates of fair value. The impact of these tax ramifications can have a significant effect on estimates of fair value.

The estimated fair values of the Corporation’s financial instruments at June 30, 2011 and December 31, 2010 are summarized as follows:

The fair value of financial assets and liabilities is categorized in three levels. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. These levels are:

•   Level 1 —Valuations based on quoted prices in active markets, such as the New York Stock Exchange. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

•   Level 2 —Valuations of assets and liabilities traded in less active dealer or broker markets. Valuations include quoted prices for similar assets and liabilities traded in the same market; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Valuations may be obtained from, or corroborated by, third-party pricing services.

•   Level 3 —Assets and liabilities with valuations that include methodologies and assumptions that may not be readily observable, including option pricing models, discounted cash flow models, yield curves and similar techniques. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities, but in all cases are corroborated by external data, which may include third-party pricing services.

In instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Corporation’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

There were no transfers between Levels 1 and 2 of the fair value hierarchy during the six months ended June 30, 2011. For the available for sale securities, the Corporation obtains fair value measurements from an independent third party service and or from independent brokers.

The Corporation has assets that, under certain conditions, are subject to measurement at fair value on a non-recurring basis. The fair value of collateral-dependent impaired loans and other real estate owned is determined through the use of an independent third-party appraisal (Level 3 input), once a loan is identified as impaired or the Corporation takes ownership of a property. The Corporation maintains a disciplined approach of obtaining updated independent third-party appraisals relating to such loans or property on at least an annual basis, at which time the determination of fair value is updated as necessary to reflect the appraisal. In addition, Management reviews the fair value of those collateral-dependent impaired loans in amounts that it considers to be material ($250,000 or greater) on a monthly basis and makes necessary adjustments to the fair value based on individual facts and circumstances, which review may include obtaining new third-party appraisals.

Mortgage Servicing Rights (MSR). The Corporation carries its mortgage servicing rights at lower of cost or fair value, and therefore, can be subject to fair value measurements on a nonrecurring basis. Since sales of mortgage servicing rights occur in private transactions and the precise terms and conditions of the sales are typically not readily available (Level 3), there is a limited market to refer to in determining the fair value of mortgage servicing rights. As such the Corporation utilizes a third party vendor to perform a valuation on the mortgage servicing rights to estimate the fair value. The Corporation reviews the estimated fair values and assumptions used by the third party vendor on a quarterly basis.

Impaired Loans. Impaired loans valued using Level 3 inputs consist of non-homogeneous loans that are considered impaired. The Corporation estimates the fair value of these loans based on the estimated realizable values of available collateral, which is typically based on current independent third-party appraisals.

Other Real Estate Owned. Other real estate owned (“OREO”) is measured and reported at fair value when the current book value exceeds the estimated fair value of the property. Management’s determination of the fair value for these loans uses a market approach representing the estimated net proceeds to be received from the sale of the property based on observable market prices and market value provided by independent, licensed or certified appraisers (Level 3 Inputs).
