|Disclosures About Fair Value of Assets and Liabilities     | DISCLOSURES ABOUT FAIR VALUE OF ASSETS AND LIABILITIESThe Corporation used fair value measurements to record fair value adjustments, to certain assets, and liabilities and to determine fair value disclosures.  The accounting guidance defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.  ASC 820 applies only when other guidance requires or permits assets or liabilities to be measured at fair value; it does not expand the use of fair value in any new circumstances.As defined in ASC 820, fair value is the price to sell an asset or transfer a liability in an orderly transaction between market participants.  It represents an exit price at the measurement date.  Market participants are buyers and sellers, who are independent, knowledgeable, and willing and able to transact in the principal (or most advantageous) market for the asset or liability being measured.  Current market conditions, including imbalances between supply and demand, are considered in determining fair value.  The Corporation values its assets and liabilities in the principal market where it sells the particular asset or transfers the liability with the greatest volume and level of activity.  In the absence of a principal market, the valuation is based on the most advantageous market for the asset or liability (i.e., the market where the asset could be sold or the liability transferred at a price that maximizes the amount to be received for the asset or minimizes the amount to be paid to transfer the liability).Valuation inputs refer to the assumptions market participants would use in pricing a given asset or liability.  Inputs can be observable or unobservable.  Observable inputs are those assumptions which market participants would use in pricing the particular asset or liability.  These inputs are based on market data and are obtained from a source independent of the Corporation.  Unobservable inputs are assumptions based on the Corporation’s own information or estimate of assumptions used by market participants in pricing the asset or liability.  Unobservable inputs are based on the best and most current information available on the measurement date.  All inputs, whether observable or unobservable, are ranked in accordance with a prescribed fair value hierarchy which gives the highest ranking to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest ranking to unobservable inputs for which there is little or no market activity (Level 3).  Fair values for assets or liabilities classified as Level 2 are based on one or a combination of the following factors: (i) quoted prices for similar assets; (ii) observable inputs for the asset or liability, such as interest rates or yield curves; or (iii) inputs derived principally from or corroborated by observable market data.  The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.  The Corporation considers an input to be significant if it drives 10 percent or more of the total fair value of a particular asset or liability.Recurring MeasurementsThe following table presents the fair value measurements of assets and liabilities recognized in the Consolidated Condensed Balance Sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall atSeptember 30, 2013, andDecember 31, 2012.Fair Value Measurements Using:September 30, 2013Fair ValueQuoted Prices in Active Markets for Identical Assets(Level 1)Significant OtherObservable Inputs(Level 2)SignificantUnobservableInputs(Level 3)Available for sale securities:U.S. Government-sponsored agency securities$3,800$3,800State and municipal202,182181,672$20,510U.S. Government-sponsored mortgage-backed securities398,169398,169Corporate obligations484484Equity securities1,7061,7024Interest rate swap asset3,0543,054Interest rate cap421421Interest rate swap liability4,5774,577Fair Value Measurements Using:December 31, 2012Fair ValueQuoted Prices inActive Markets forIdentical Assets(Level 1)Significant Other Observable Inputs(Level 2)SignificantUnobservableInputs(Level 3)Available for sale securities:U.S. Government-sponsored agency securities$4,640$4,640State and municipal158,194140,094$18,100U.S. Government-sponsored mortgage-backed securities348,579348,579Corporate obligations224224Equity securities1,7061,7024Interest rate swap asset6,1036,103Interest rate cap197197Interest rate swap liability9,7669,766Following is a description of the valuation methodologies and inputs used for instruments measured at fair value on a recurring basis and recognized in the accompanying Consolidated Condensed Balance Sheets, as well as the general classification of such instruments pursuant to the valuation hierarchy.  There have been no significant changes in the valuation techniques as ofSeptember 30, 2013.Available for Sale Investment SecuritiesWhere quoted, market prices are available in an active market and securities are classified within Level 1 of the valuation hierarchy.  There are no securities classified within Level 1 of the hierarchy.  If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows.  Level 2 securities include agencies, mortgage backs, state and municipal, and equity securities.  In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy.  Level 3 fair value, including corporate obligations, state and municipal and equity securities, was determined using a discounted cash flow model that incorporated market estimates of interest rates and volatility in markets that have not been active.Third party vendors compile prices from various sources and may apply such techniques as matrix pricing to determine the value of identical or similar investment securities classified within Level 2.  Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities without relying exclusively on quoted prices for specific investment securities but rather relying on the investment securities’ relationship to other benchmark quoted investment securities.  Any investment security not valued based upon the methods above are considered Level 3.Pooled Trust Preferred SecuritiesPooled trust preferred securities are classified as Level 3 inputs in the fair value hierarchy.  These securities were rated A or better at inception, but atSeptember 30, 2013, Moody’s ratings on these securities ranged from Ca to C.  The issuers in these securities are primarily banks, but some of the pools do include a limited number of insurance companies.  On a quarterly basis, the Corporation uses an other-than-temporary impairment (“OTTI”) evaluation process to compare the present value of expected cash flows to determine whether an adverse change in cash flows has occurred.  The OTTI evaluation process considers the structure and term of the collateralized debt obligation (“CDO”), interest rates, principal balances of note classes and underlying issuers, the timing and amount of interest and principal payments of the underlying issuers, and the allocation of the payments to the note classes.  The current estimate of expectedcash flows is based on the most recent trustee reports and any other relevant market information including announcements of interest payment deferrals or defaults of underlying trust preferred securities. Assumptions used in the evaluation process include expected future default rates and prepayments as well as recovery assumptions on defaults and deferrals.  In addition, the process is used to “stress” each CDO, or make assumptions more severe than expected activity, to determine the degree to which assumptions could deteriorate before the CDO could no longer fully support repayment of the Corporation’s note class.  Upon completion of theSeptember 30, 2013quarterly evaluation process, the conclusion was no OTTI for the three months endingSeptember 30, 2013.   No OTTI was recognized fornine months ended September 30, 2013and2012.Interest Rate Derivative AgreementsSee information regarding the Corporation's interest rate derivative products in NOTE 6.  DERIVATIVE FINANCIAL INSTRUMENTS, included within the Notes to Consolidated Condensed Financial Statements of this Form 10-Q.The fair value of the interest rate swap and cap instruments were transferred from Level 3 to Level 2 as of March 31, 2012 due to the availability of additional valuation information.  These instruments were valued using widely accepted valuation techniques including discounted cash flow analysis using observable inputs such as contractual terms and LIBOR-based rate curves.Level 3 ReconciliationThe following is a reconciliation of the beginning and ending balances of recurring fair value measurements recognized in the Consolidated Condensed Balance Sheets using significant unobservable (Level 3) inputs forthree and nine months ended September 30, 2013, and2012.Three Months Ended September 30, 2013Nine Months Ended September 30, 2013Availablefor SaleSecuritiesInterestRate SwapAssetInterestRateCapInterest Rate SwapLiabilityAvailablefor SaleSecuritiesInterestRate SwapAssetInterestRateCapInterestRate SwapLiabilityBalance at beginning of the period$17,915$18,328Total realized and unrealized gains and losses:Included in net income (loss)Included in other comprehensive income(486)(521)Purchases, issuances and settlementsTransfers in/(out) of Level 33,9053,905Principal payments/additions(336)(714)Ending balance at September 30, 2013$20,998$20,998Three Months Ended September 30, 2012Nine Months Ended September 30, 2012Availablefor Sale SecuritiesInterestRate SwapAssetInterestRateCapInterest Rate SwapLiabilityAvailablefor Sale SecuritiesInterestRate SwapAssetInterestRateCapInterestRate Swap LiabilityBalance at beginning of the period$19,740$20,838$5,241$424$(7,797)Total realized and unrealized gains and losses:Included in net income (loss)(860)863Included in other comprehensive income(183)(944)481(15)Purchases, issuances and settlementsTransfers in/(out) of Level 3(4,862)(409)6,934Principal payments(1,132)(1,469)Ending balance at  September 30, 2012$18,425$18,425$—$—$—There were no gains or losses for the period included in earnings that were attributable to the changes in unrealized gains or losses related to assets or liabilities held atSeptember 30, 2013orDecember 31, 2012.Transfers Between LevelsTransfer between Levels 1, 2 and 3 and the reasons for those transfers are as follows:Three and Nine Months Ended September 30, 2013Quoted Prices in Active Markets for Identical Assets (Level 1)Significant Other Observable Inputs(Level 2)Significant Unobservable Inputs(Level 3)Reason for TransferTransfers to/(from) Level:Available for sale securities$(3,905)$3,905Selected state and municipal securities were transferred from Level 2 to Level 3 due to limited availability of similar securities in active markets.$(3,905)$3,905Nine Months Ended September 30, 2012Quoted Prices inActive Markets for Identical Assets(Level 1)Significant OtherObservable Inputs(Level 2)Significant Unobservable Inputs(Level 3)Reason for TransferTransfers to/(from) Level:Interest rate swap asset$4,862$(4,862)The interest rate swap and cap instruments were transferred from Level 3 to Level 2 as of March 31, 2012 due to the availability of additional valuation information.

Allowable methods for determining the amount of impairment include estimating fair value of the collateral for collateral dependent loans.  If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized.  This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value.  A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance.  If these allocations cause the allowance for loan losses to increase, such increase is reported as a component of the provision for loan losses.  Loan losses are charged against the allowance when management believes the uncollectability of the loan is confirmed.  During2013, certain impaired loans were partially charged off or re-evaluated.  Impaired loans that are collateral dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method.Other Real Estate OwnedThe fair value for impaired loans and other real estate owned is measured based on the value of the collateral securing those loans or real estate and is determined using several methods.  The fair value of real estate is generally determined based on appraisals by qualified licensed appraisers.  The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach.  If an appraisal is not available, the fair value may be determined by using a cash flow analysis.  Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of,  asset appraisals, accounts receivable aging reports, inventory listings and/or customer financial statements.   Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions.Unobservable (Level 3) InputsThe following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements, other than goodwill, atSeptember 30, 2013.Fair ValueValuation TechniqueUnobservable InputsRangeState and municipal securities$20,510Discounted cash flowMaturity/Call date1 month to 10 yrsBlend of US Muni BQ curveA- to BBB-Discount rate1% - 5%Corporate obligations/Equity securities$488Discounted cash flowRisk free rate3 month LIBORplus Premium for illiquidityplus 200bpsImpaired loans (collateral dependent)$8,874Collateral based measurementsDiscount to reflect current market conditions and ultimate collectability0% - 50%Other real estate owned$8,220AppraisalsDiscount to reflect current market conditions0% - 20%Sensitivity of Significant Unobservable InputsThe following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement.State and Municipal SecuritiesThe significant unobservable inputs used in the fair value measurement of the Corporation’s state and municipal securities are premiums for unrated securities and marketability discounts.  Significant increases or decreases in either of those inputs in isolation would result in a significantly lower or higher fair value measurement.  Generally, changes in either of those inputs will not affect the other input.Corporate Obligations/Equity SecuritiesThe significant unobservable inputs used in the fair value measurement of the Corporation’s corporate obligations/equity securities are premiums for unrated securities and marketability discounts.  Significant increases or decreases in either of those inputs in isolation would result in a significantly lower or higher fair value measurement.  Generally, changes in either of those inputs will not affect the other input.Fair Value of Financial InstrumentsThe following table presents estimated fair values of the Corporation’s financial instruments and the level within the fair value hierarchy in which the fair value measurements fall atSeptember 30, 2013, andDecember 31, 2012.September 30, 2013(unaudited)CarryingAmountQuoted Prices in Active Marketsfor IdenticalAssetsSignificantOtherObservableInputsSignificant UnobservableInputs(Level 1)(Level 2)(Level 3)Assets:Cash and due from banks$92,341$92,341Interest-bearing time deposits18,87518,875Investment securities available for sale606,341$585,343$20,998Investment securities held to maturity307,794303,37111,012Mortgage loans held for sale5,3125,312Loans2,859,2332,822,465Federal Reserve Bank and Federal Home Loan Bank stock32,79032,790Interest rate swap and cap asset3,4753,475Interest receivable16,17116,171Liabilities:Deposits$3,255,846$2,548,183$700,168Borrowings:Federal funds purchased115,938115,938Securities sold under repurchase agreements123,935124,195Federal Home Loan Bank advances172,292173,449Subordinated debentures and term loans111,84963,391Interest rate swap liability4,5774,577Interest payable1,1551,155December 31, 2012CarryingAmountQuoted Prices in Active Marketsfor IdenticalAssetsSignificantOtherObservableInputsSignificant UnobservableInputs(Level 1)(Level 2)(Level 3)Assets:Cash and due from banks$101,460$101,460Interest-bearing time deposits38,44338,443Investment securities available for sale513,343$495,015$18,328Investment securities held to maturity361,020366,59011,584Mortgage loans held for sale22,30022,300Loans2,832,8432,852,614Federal Reserve Bank and Federal Home Loan Bank stock32,78532,785Interest rate swap and cap asset6,3006,300Interest receivable16,36716,367Liabilities:Deposits$3,346,383$2,478,706$865,793Borrowings:Federal funds purchased18,86218,862Securities sold under repurchase agreements141,828142,318Federal Home Loan Bank advances94,23897,357Subordinated debentures and term loans112,16162,133Interest rate swap liability9,7669,766Interest payable1,8411,841The following methods were used to estimate the fair value of all other financial instruments recognized in the Consolidated Condensed Balance Sheets at amounts other than fair value.Cash and due from banks:  The fair value of cash and cash equivalents approximates carrying value.Interest-bearing time deposits:  The fair value of interest-bearing time deposits approximates carrying value.Investment securities:  Fair value is based on quoted market prices, if available.  If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.  The fair value of certain Level III securities is estimated using discounted cash flow analysis, using interest rates currently being offered on investments with similar maturities and investment quality.Mortgage Loans Held For Sale:The carrying amount approximates fair value due to the short duration between origination and date of sale.Loans:The fair value for loans is estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  See Impaired Loans above.Federal Reserve and Federal Home Loan Bank stock:  The fair value of Federal Reserve Bank and Federal Home Loan Bank stock is based on the price which it may be resold to the Federal Reserve and Federal Home Loan Bank.Derivative instruments:  The fair value of the interest rate swaps reflects the estimated amounts that would have been received to terminate these contracts at the reporting date based upon pricing or valuation models applied to current market information.  Interest rate caps are valued using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rose above the strike rate of the caps.  The projected cash receipts on the caps are based on an expectation of future interest rates derived from observed market interest rate curves and volatilities.Interest Receivable and Interest Payable:  The fair value of interest receivables/payable approximates the carrying amount.Deposits:The fair values of noninterest-bearing and interest-bearing demand accounts and savings deposits are equal to the amount payable on demand at the balance sheet date.  The carrying amounts for variable rate, fixed-term certificates of deposit approximate their fair values at the balance sheet date.  Fair values for fixed-rate certificates of deposit and other time deposits are estimated using a discounted cash flow calculation that applies interest rates currently being offered to a schedule of aggregated expected monthly maturities on such time deposits.Federal funds purchased:  The fair value of Federal Funds purchased approximates the carrying amount.Borrowings:The fair value of borrowings is estimated using a discounted cash flow calculation, based on current rates for similar debt.
