|Fair Values of Assets and Liabilities                   | Fair Value of Assets and LiabilitiesFNB utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale, derivatives and mortgage servicing rights are recorded at fair value on a recurring basis. Additionally, from time-to-time, FNB may be required to record at fair value other assets and liabilities on a non-recurring basis, such as loans held for sale, loans held for investment and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve application of lower or cost or market accounting or write-downs of individuals’ assets or liabilities.Fair Value HierarchyFNB groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:Level 1: Valuation is based upon quoted prices for identical instruments traded in active markets.Level 2: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.Level 3: Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.The following is a description of valuation methodologies used for assets and liabilities recorded at fair value:Investments Securities Available-for-SaleInvestment securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 may include asset-backed securities in less liquid markets.Liquidity is a significant factor in the determination of the fair values of available-for-sale debt securities. Market price quotes may not be readily available for some positions, or positions within a market sector where trading activity has slowed significantly or ceased. Some of these instruments are valued using a discounted cash flow model, which estimates the fair value of the securities using internal credit risk, interest rate and prepayment risk models that incorporate management’s best estimate of current key assumptions such as default rates, loss severity and prepayment rates. Principal and interest cash flows are discounted using an observable discount rate for similar instruments with adjustments that management believes a market participant would consider in determining fair value for the specific security. Underlying assets are valued using external pricing services, where available, or matrix pricing based on the vintages and ratings. Situations of illiquidity generally are triggered by the market’s perception of credit uncertainty regarding a single company or a specific market sector. In these instances, fair value is determined based on limited available market information and other factors, principally from reviewing the issuer’s financial statements and changes in credit ratings made by one or more ratings agencies.Loans Held for SaleLoans held for sale are carried at the lower of cost or fair value less estimated costs to sell. Once sold, the loans are beyond the reach of FNB in all respects and the purchasing investor has all rights of ownership, including the ability to pledge or exchange the loans. Most of the loans sold are without recourse. Gains or losses on loan sales are recognized at the time of sale, are determined by the difference between net sales proceeds and the carrying value of the loan sold, and are included in Consolidated Statements of Operations.Since loans held for sale are carried at the lower of cost or fair value, the fair value of loans held for sale is based on contractual agreements with independent third-party buyers. As such, FNB classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2.Loans Held for InvestmentFNB does not record loans held for investment at fair value on a recurring basis. However, from time to time, a loan is considered impaired and the related impairment is charged against the allowance or a specific allowance is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as impaired, management determines the fair value of the loan to quantify impairment, should such exist. The fair value of impaired loans is estimated using one of several methods, including collateral net liquidation value, market value of similar debt, enterprise value, and discounted cash flows. Those impaired loans not requiring a specific allowance represent loans for which the fair value of the expected repayments or collateral meet or exceed the recorded investments in such loans. At December 31, 2012 and December 31, 2011, substantially all of the total impaired loans were evaluated based on the fair value of the collateral. Impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, FNB records the impaired loan as nonrecurring Level 3. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and given the lack of observable market prices for identical properties, FNB records the impaired loans as nonrecurring Level 3.Other Real Estate OwnedOREO is adjusted to fair value upon transfer of the loans to OREO. Subsequently, OREO is carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. Given the lack of observable market prices for identical properties, FNB records the OREO as nonrecurring Level 3.Derivative Assets and LiabilitiesSubstantially all derivative instruments held or issued by FNB for risk management or customer-initiated activities are traded in over-the-counter markets where quoted market prices are not readily available. For those derivatives, FNB measures fair value using models that use primarily market observable inputs, such as yield curves and option volatilities, and include the value associated with counterparty credit risk. FNB classifies derivatives instruments held or issued for risk management or customer-initiated activities as Level 2.Mortgage Servicing RightsMortgage servicing rights are recorded at fair value on a recurring basis, with changes in fair value recorded as a component of mortgage loan sales. A valuation model, which utilizes a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and a discount rate, is used to determine fair value. Loan servicing rights are adjusted to fair value through a valuation allowance as determined by the model. As such, FNB classifies mortgage servicing rights as Level 3. Pursuant to an agreement dated December 29, 2010, CommunityOne sold its mortgage servicing rights on mortgages owned by Fannie Mae and transferred the servicing of those mortgages on January 31, 2011.

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 FNB's entire holdings of a particular financial instrument.Because no market exists for a portion of FNB'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 of Financial InstrumentsThe following methods and assumptions were used to estimate the fair value for each class of FNB's financial instruments.Cash and cash equivalents.Fair value equals the carrying value of such assets due to their nature and is classified as Level 1.Investment securities.The fair value of investment securities 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 equity investments in the restricted stock of the FRBR and FHLB approximates the carrying value. The fair value of investment securities is classified as Level 2.Loans held for sale.Substantially all residential mortgage loans held for sale are pre-sold and their carrying value approximates fair value.  FNB classified the fair value of loans held for sale as Level 2.Loans held for investment.The fair value of fixed rate loans is estimated 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.  Substantially all residential mortgage loans held for sale are pre-sold and their carrying value approximates fair value.  The fair value of variable rate loans with frequent repricing and negligible credit risk approximates book value.  The fair value of loans is further discounted by credit and liquidity factors.  FNB classified the fair value of loans as Level 3.Accrued interest receivable and payable.The carrying amounts of accrued interest payable and receivable approximate fair value and are classified as Level 2.Deposits.The fair value of noninterest-bearing and interest-bearing demand deposits and savings are the amounts payable on demand because these products have no stated maturity.  The fair value of time deposits is estimated using the rates currently offered for deposits of similar remaining maturities and are classified as Level 2.Borrowed funds.The carrying value of retail repurchase agreements and federal funds purchased is considered to be a reasonable estimate of fair value.  The fair value of FHLB advances and other borrowed funds is estimated using the rates currently offered for advances of similar remaining maturities and are classified as Level 2.Junior subordinated debentures.Included in junior subordinated debentures are variable rate trust preferred securities issued by FNB.  Fair values for the trust preferred securities were estimated by developing cash flow estimates for each of these debt instruments based on scheduled principal and interest payments and current interest rates.  Once the cash flows were determined, a rate for comparable subordinated debt was used to discount the cash flows to the present value.  The estimated fair value for FNB's junior subordinated debentures have declined due to wider credit spreads (i.e., spread to LIBOR) on similar trust preferred issues. This is due, in part, to proposed bank regulatory changes in bank capital structure. FNB classified the fair value of junior subordinated debentures as Level 3.Financial instruments with off-balance sheet risk.The fair value of financial instruments with off-balance sheet risk is considered to approximate carrying value, since the large majority of these future financing commitments would result in loans that have variable rates and/or relatively short terms to maturity.  For other commitments, generally of a short-term nature, the carrying value is considered to be a reasonable estimate of fair value.The estimated fair values of financial instruments for continuing operations at December 31 are as follows:At December 31, 2012(dollars in thousands)Carrying ValueEstimated Fair ValueLevel 1Level 2Level 3Financial Assets of Continuing Operations:Cash and cash equivalents$239,610$239,610$239,610$—$—Investment securities:  Available-for-sale564,850564,850—564,850—Loans held for sale6,9746,974—6,974—Loans, net1,147,7211,140,088——1,140,088Accrued interest receivable6,1026,102—6,102—Financial Liabilities of Continuing Operations:Deposits1,906,9881,910,927—1,910,927—Retail repurchase agreements8,6758,675—8,675—Federal Home Loan Bank advances58,32862,950—62,950—Junior subordinated debentures56,70218,760——18,760Accrued interest payable2,1112,111—2,111—At December 31, 2011(dollars in thousands)Carrying ValueEstimated Fair ValueLevel 1Level 2Level 3Financial Assets of Continuing Operations:Cash and cash equivalents553,416553,416553,416——Investment securities:  Available-for-sale431,306431,306—431,306—Loans held for sale4,5294,529—4,529—Loans, net1,178,1751,176,795——1,176,795Accrued interest receivable5,9195,919—5,919—Financial Liabilities of Continuing Operations:Deposits2,129,1112,139,093—2,139,093—Retail repurchase agreements8,8388,838—8,838—Federal Home Loan Bank advances58,37062,555—62,555—Junior subordinated debentures56,70236,218——36,218Accrued interest payable1,6541,654—1,654—The estimated fair values of financial instruments for discontinued operations are as follows:As of December 31, 2012As of December 31, 2011(dollars in thousands)CarryingValueEstimatedFair ValueCarryingValueEstimatedFair ValueFinancial Assets of Discontinued Operations$—$—$233$233There werenotransfers between valuation levels for any assets during the years ended December 31, 2012 or December 31, 2011. If different valuation techniques are deemed necessary, we would consider those transfers to occur at the end of the period when the assets are valued.The fair value estimates are made at a specific point in time based on relevant market and other information about the financial instruments. Because no market exists for a significant portion of FNB’s financial instruments, fair value estimates are based on current economic conditions, risk characteristics of various financial instruments, and such 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. 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 the estimates.
