1. Summary of Significant Accounting Policies

Basis of Presentation

The Corporation’s accompanying consolidated financial statements and these notes to the financial statements include subsidiaries in which the Corporation has a controlling financial interest. The Corporation owns and operates FNBPA, First National Trust Company, First National Investment Services Company, LLC, F.N.B. Investment Advisors, Inc., First National Insurance Agency, LLC, Regency, F.N.B. Capital Corporation, LLC and Bank Capital Services, LLC, and includes results for each of these entities in the accompanying consolidated financial statements.

The accompanying consolidated financial statements include all adjustments that are necessary, in the opinion of management, to fairly reflect the Corporation’s financial position and results of operations in accordance with U.S. generally accepted accounting principles (GAAP). All significant intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. Events occurring subsequent to the date of the balance sheet have been evaluated for potential recognition or disclosure in the consolidated financial statements through the date of the filing of the consolidated financial statements with the Securities and Exchange Commission (SEC).

Use of Estimates

The accounting and reporting policies of the Corporation conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant changes include the allowance for loan losses, securities valuations, goodwill and other intangible assets and income taxes.

Business Combinations

Business combinations are accounted for by applying the acquisition method in accordance with Accounting Standards Codification (ASC) 805, Business Combinations. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statement of income from the date of acquisition.

Cash Equivalents

The Corporation considers cash and demand balances due from banks as cash and cash equivalents.

Securities

Investment securities, which consist of debt securities and certain equity securities, comprise a significant portion of the Corporation’s consolidated balance sheet. Such securities can be classified as “trading,” “securities held to maturity” or “securities available for sale.”

Securities are classified as trading securities when management intends to sell such securities in the near term and are carried at fair value, with unrealized gains (losses) reflected through the consolidated statement of income. The Corporation acquired securities in conjunction with acquisitions during 2013 and 2012 that the Corporation classified as trading securities. The Corporation both acquired and sold these trading securities during the quarters in which each of the acquisitions occurred. As of December 31, 2013 and 2012, the Corporation did not hold any trading securities.

Securities held to maturity are comprised of debt securities, for which management has the positive intent and ability to hold such securities until their maturity. Such securities are carried at cost, adjusted for related amortization of premiums and accretion of discounts through interest income from securities, and other-than-temporary impairment (OTTI), if any.

Securities that are not classified as trading or held to maturity are classified as available for sale. The Corporation’s available for sale securities portfolio is comprised of debt securities and marketable equity securities. Such securities are carried at fair value with net unrealized gains and losses deemed to be temporary and unrealized losses deemed to be other-than-temporary and attributable to non-credit factors reported separately as a component of other comprehensive income, net of tax. Realized gains and losses on the sale of available for sale securities and credit-related OTTI charges are recorded within non-interest income in the consolidated statement of income. Realized gains and losses on the sale of securities are determined using the specific-identification method.

The Corporation evaluates its investment securities portfolio for OTTI on a quarterly basis. Impairment is assessed at the individual security level. The Corporation considers an investment security impaired if the fair value of the security is less than its cost or amortized cost basis.

When impairment of an equity security is considered to be other-than-temporary, the security is written down to its fair value and an impairment loss is recorded as a loss within non-interest income in the consolidated statement of income. When impairment of a debt security is considered to be other-than-temporary, the amount of the OTTI recorded as a loss within non-interest income and thereby recognized in earnings depends on whether the Corporation intends to sell the security or whether it is more likely than not that the Corporation will be required to sell the security before recovery of its amortized cost basis.

If the Corporation intends to sell the debt security or more likely than not will be required to sell the security before recovery of its amortized cost basis, OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value.

If the Corporation does not intend to sell the debt security and it is not more likely than not the Corporation will be required to sell the security before recovery of its amortized cost basis, OTTI shall be separated into the amount representing credit loss and the amount related to all other market factors. The amount related to credit loss shall be recognized in earnings. The amount related to other market factors shall be recognized in other comprehensive income, net of applicable taxes.

The Corporation performs its OTTI evaluation process in a consistent and systematic manner and includes an evaluation of all available evidence. Documentation of the process is as extensive as necessary to support a conclusion as to whether a decline in fair value below cost or amortized cost is temporary or other-than-temporary and includes documentation supporting both observable and unobservable inputs and a rationale for conclusions reached. In making these determinations for pooled trust preferred securities (TPS), the Corporation consults with third-party advisory firms to provide additional valuation assistance.

This process considers factors such as the severity, length of time and anticipated recovery period of the impairment, recoveries or additional declines in fair value subsequent to the balance sheet date, recent events specific to the issuer, including investment downgrades by rating agencies and economic conditions in its industry, and the issuer’s financial condition, repayment capacity, capital strength and near-term prospects.

For debt securities, the Corporation also considers the payment structure of the debt security, the likelihood of the issuer being able to make future payments, failure of the issuer of the security to make scheduled interest and principal payments, whether the Corporation has made a decision to sell the security and whether the Corporation’s cash or working capital requirements or contractual or regulatory obligations indicate that the debt security will be required to be sold before a forecasted recovery occurs. For equity securities, the Corporation also considers its intent and ability to retain the security for a period of time sufficient to allow for a recovery in fair value. Among the factors that the Corporation considers in determining its intent and ability to retain the security is a review of its capital adequacy, interest rate risk position and liquidity. The assessment of a security’s ability to recover any decline in fair value, the ability of the issuer to meet contractual obligations, the Corporation’s intent and ability to retain the security, and whether it is more likely than not the Corporation will be required to sell the security before recovery of its amortized cost basis require considerable judgment.

Debt securities with credit ratings below AA at the time of purchase that are repayment-sensitive securities are evaluated using the guidance of ASC 325, Investments – Other. All other securities are required to be evaluated under ASC 320, Investments – Debt Securities.

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold plus accrued interest. Securities, generally U.S. government and federal agency securities, pledged as collateral under these financing arrangements cannot be sold or repledged by the secured party. The fair value of collateral either received from or provided to a third party is continually monitored and additional collateral is obtained or is requested to be returned to the Corporation as deemed appropriate.

Derivative Instruments and Hedging Activities

From time to time, the Corporation may enter into derivative transactions principally to protect against the risk of adverse price or interest rate movements on the value of certain assets and liabilities and on future cash flows. The Corporation formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking each hedge transaction. All derivative instruments are carried at fair value on the balance sheet in accordance with the requirements of ASC 815, Derivatives and Hedging.

Cash flow hedges are accounted for by recording the fair value of the derivative instrument on the balance sheet as either a freestanding asset or liability, with a corresponding offset recorded in accumulated other comprehensive income, net of tax. Amounts are reclassified from accumulated other comprehensive income to the consolidated statement of income in the period or periods in which the hedged transaction affects earnings.

Derivative gains and losses under cash flow hedges not effective in hedging the change in fair value or expected cash flows of the hedged item are recognized immediately in the consolidated statement of income. At the hedge’s inception and at least quarterly thereafter, a formal assessment is performed to determine whether changes in the fair values or cash flows of the derivative instruments have been highly effective in offsetting changes in fair values or cash flows of the hedged items and whether they are expected to be highly effective in the future. If it is determined a derivative instrument has not been or will not continue to be highly effective as a hedge, hedge accounting is discontinued.

In addition, the Corporation enters into interest rate swap agreements to meet the financing, interest rate and equity risk management needs of qualifying commercial loan customers. These agreements provide the customer the ability to convert from variable to fixed interest rates. The Corporation then enters into positions with a derivative counterparty in order to offset its exposure on the fixed components of the customer agreements. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. The Corporation seeks to minimize counterparty credit risk by entering into transactions with only high-quality institutions. These arrangements meet the definition of derivatives, but are not designated as hedging instruments under ASC 815,Derivatives and Hedging. The interest rate swap agreement with the loan customer and with the counterparty is reported at fair value in other assets and other liabilities on the consolidated balance sheet with any resulting gain or loss recorded in current period earnings as other income.

Mortgage Loans Held for Sale and Loan Commitments

Certain residential mortgage loans are originated for sale in the secondary mortgage loan market and typically sold with servicing rights released. These loans are classified as loans held for sale and are carried at the lower of cost or estimated market value on an aggregate basis. Market value is determined on the basis of rates obtained in the respective secondary market for the type of loan held for sale. Loans are generally sold at a premium or discount from the carrying amount of the loan. Such premium or discount is recognized at the date of sale. Gain or loss on the sale of loans is recorded in non-interest income at the time consideration is received and all other criteria for sales treatment have been met.

The Corporation routinely issues commitments to make loans that it intends to sell. These commitments are considered derivatives. The Corporation also enters into commitments to sell loans to mitigate the risk that the market value of residential loans may decline between the time the rate commitment is issued to the customer and the time the Corporation contracts to sell the loan. These commitments and sales contracts are also derivatives. Both types of derivatives are recorded at fair value. Sales contracts and commitments to sell loans are not designated as hedges of the fair value of loans held for sale. Fair value adjustments related to derivatives are recorded in current period earnings as part of mortgage banking income.

Loans (Excluding Acquired Loans)

Loans the Corporation originates and intends to hold for the foreseeable future or until maturity or payoff are reported at their net book balances, net of any deferred origination fees or costs. Interest income on loans is computed over the term of the loans using the effective interest method. Loan origination fees and certain direct costs incurred to extend credit are deferred and amortized over the term of the loan or loan commitment period as an adjustment to the related loan yield.

Non-performing Loans

Interest is not accrued on loans where collectibility is uncertain. The Corporation discontinues interest accruals on originated loans generally when principal or interest is due and has remained unpaid for a certain number of days unless the loan is both well secured and in the process of collection. Commercial loans are placed on non-accrual at 90 days, installment loans are placed on non-accrual at 120 days and residential mortgages and consumer lines of credit are generally placed on non-accrual at 180 days. Past due status is based on the contractual terms of the loan.

When a loan is placed on non-accrual status, all unpaid interest is reversed. Payments subsequently received are generally applied to either principal or interest or both, depending on management’s evaluation of collectibility. A loan is returned to accrual status when principal and interest are no longer past due and collectibility is probable. This generally requires a sustained period of timely principal and interest payments.

Loans are generally written off when deemed uncollectible or when they reach a predetermined number of days past due depending upon loan product, terms, and other factors. Recoveries of amounts previously charged off are credited to the allowance for loan losses.

The Corporation considers a loan impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. The impairment loss is measured by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral, less estimated selling costs, if the loan is collateral dependent. Acquired impaired loans are not classified as non-performing assets as the loans are considered to be performing under the provisions of ASC 310-30,Loans and Debt Securities Acquired with Deteriorated Credit Quality.

Restructured loans are those in which concessions of terms have been made as a result of deterioration in a borrower’s financial condition. In general, the modification or restructuring of a debt constitutes a troubled debt restructuring (TDR) if the Corporation for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that the Corporation would not otherwise consider under current market conditions. Debt restructurings or loan modifications for a borrower occur during the normal course of business and do not necessarily constitute TDRs. To designate a loan as a TDR, the presence of both borrower financial distress and a concession of terms must exist. Additionally, a loan designated as a TDR does not necessarily result in the automatic placement of the loan on non-accrual status. When the full collection of principal and interest is reasonably assured on a loan designated as a TDR and the borrower does not otherwise meet the criteria for non-accrual status, the Corporation will continue to accrue interest on the loan.

In accordance with ASC 310-40, a restructured acquired loan that is accounted for as a component of a pool in accordance with ASC 310-30 is not considered a TDR.

Allowance for Loan Losses

The allowance for loan losses is established as losses are estimated to have occurred through a provision charged to earnings. Loan losses are charged against the allowance for loan losses when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for loan losses. Allowances for impaired loans are generally determined based on collateral values or the present value of estimated cash flows. Changes in the allowance for loan losses related to impaired loans are charged or credited to the provision for loan losses.

The allowance for loan losses is maintained at a level that, in management’s judgment, is believed adequate to absorb probable losses associated with specifically identified loans, as well as estimated probable credit losses inherent in the remainder of the loan portfolio. Adequacy of the allowance for loan losses is based on management’s evaluation of potential loan losses in the loan portfolio, which includes an assessment of past experience, current economic conditions in specific industries and geographic areas, general economic conditions, known and inherent risks in the loan portfolio, the estimated value of underlying collateral and residuals and changes in the composition of the loan portfolio. Determination of the allowance for loan losses is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans based on historical loss experience and consideration of current environmental factors and economic trends, all of which are susceptible to significant change.

Credit impaired loans obtained through acquisitions are accounted for under the provisions of ASC 310-30. The Corporation also accounts for certain acquired loans considered performing at the time of acquisition by analogy to ASC 310-30. ASC 310-30 requires the initial recognition of acquired loans at the present value of amounts expected to be received. Any deterioration in the credit quality of acquired loans subsequent to acquisition would be considered in the allowance for loan losses.

Acquired Loans

Acquired loans (impaired and non-impaired) are initially recorded at their acquisition-date fair values. Fair values are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, default rates, loss severity, collateral values, discount rates, payment speeds, prepayment risk, and liquidity risk.

The carryover of allowance for loan losses related to acquired loans is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. The allowance for loan losses on acquired loans reflects only those losses incurred after acquisition and represents the present value of cash flows expected at acquisition that is no longer expected to be collected.

At acquisition, the Corporation considers the following factors as indicators that an acquired loan has evidence of deterioration in credit quality and is therefore impaired and in the scope of ASC 310-30:

•

loans that were 90 days or more past due;

•

loans that had an internal risk rating of substandard or worse. Substandard is consistent with regulatory definitions and is defined as having a well-defined weakness that jeopardizes liquidation of the loan;

•

loans that were classified as non-accrual by the acquired bank at the time of acquisition; or

•

loans that had been previously modified in a TDR.

Any acquired loans that were not individually in the scope of ASC 310-30 because they didn’t meet the criteria above were pooled into groups of similar loans based on various factors including borrower type, loan purpose, and collateral type. For these pools, the Corporation used certain loan information, including outstanding principal balance, estimated expected losses, weighted average maturity, weighted average margin, and weighted average interest rate along with estimated prepayment rates, probability of default and loss given default to estimate the expected cash flow for each loan pool.

Pursuant to an American Institute of CPAs (AICPA) letter dated December 18, 2009, the AICPA summarized the SEC staff’s view regarding accounting in subsequent periods for discount accretion associated with acquired loan receivables that are not required to be accounted for in accordance with ASC 310-30. The AICPA understands that, in the absence of further standard setting, the SEC staff would not object to an accounting policy based on contractual cash flows (ASC 310-20 approach) or an accounting policy based on expected cash flows (ASC 310-30 approach). The Corporation believes analogizing to ASC 310-30 is the more appropriate option to follow in accounting for discount accretion on non-impaired acquired loans other than revolving loans and therefore accounts for such loans in accordance with ASC 310-30. ASC 310-30 guidance does not apply to revolving loans. Consequently, discount accretion on revolving loans acquired is accounted for using the ASC 310-20 approach.

The excess of cash flows expected to be collected at acquisition over recorded fair value is referred to as the accretable yield. The accretable yield is recognized into income over the remaining life of the loan if the timing and/or amount of cash flows expected to be collected can be reasonably estimated (the accretion model). If the timing and/or amount of cash flows expected to be collected cannot be reasonably estimated, the cost recovery method of income recognition must be used. The difference between the loan’s total scheduled principal and interest payments over all cash flows expected at acquisition is referred to as the non-accretable difference. The non-accretable difference represents contractually required principal and interest payments which the Corporation does not expect to collect.

Over the life of the acquired loan, the Corporation continues to estimate cash flows expected to be collected. Decreases in expected cash flows, other than from prepayments or rate adjustments, are recognized as impairments through a charge to the provision for loan losses resulting in an increase in the allowance for loan losses. Subsequent improvements in cash flows result in first, reversal of existing valuation allowances recognized subsequent to acquisition, if any, and next, an increase in the amount of accretable yield to be subsequently recognized on a prospective basis over the loan’s remaining life.

Acquired loans that met the criteria for non-accrual of interest prior to acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Corporation can reasonably estimate the timing and amount of expected cash flows on such loans. Accordingly, the Corporation does not consider acquired contractually delinquent loans to be non-accrual or non-performing and continues to recognize interest income on these loans using the accretion model.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the asset’s estimated useful life. Leasehold improvements are expensed over the lesser of the asset’s estimated useful life or the term of the lease including renewal periods when reasonably assured. Useful lives are dependent upon the nature and condition of the asset and range from 3 to 40 years. Maintenance and repairs are charged to expense as incurred, while major improvements are capitalized and amortized to operating expense over the identified useful life.

Other Real Estate Owned

Other real estate owned (OREO) is comprised principally of commercial and residential real estate properties obtained in partial or total satisfaction of loan obligations. OREO acquired in settlement of indebtedness is included in other assets initially at the lower of estimated fair value of the asset less estimated selling costs or the carrying amount of the loan. Changes to the value subsequent to transfer are recorded in non-interest expense along with direct operating expenses. Gains or losses not previously recognized resulting from sales of OREO are recognized in non-interest expense on the date of sale.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as core deposit intangibles, customer relationship intangibles and renewal lists, are amortized over their estimated useful lives and subject to periodic impairment testing. Core deposit intangibles are primarily amortized over ten years using straight line and accelerated methods. Customer and renewal lists and other intangible assets are amortized over their estimated useful lives which range from ten to twelve years.

Goodwill and other intangibles are subject to impairment testing at the reporting unit level, which must be conducted at least annually. The Corporation performs impairment testing during the fourth quarter of each year. Due to ongoing uncertainty regarding market conditions surrounding the banking industry, the Corporation continues to monitor goodwill and other intangibles for impairment and to evaluate carrying amounts, as necessary.

The Corporation performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing updated qualitative factors, the Corporation determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it does not have to perform the two-step goodwill impairment test. Determining the fair value of a reporting unit under the first step of the goodwill impairment test and determining the fair value of individual assets and liabilities of a reporting unit under the second step of the goodwill impairment test are judgmental and often involve the use of significant estimates and assumptions. Similarly, estimates and assumptions are used in determining the fair value of other intangible assets. Estimates of fair value are primarily determined using discounted cash flows, market comparisons and recent transactions. These approaches use significant estimates and assumptions including projected future cash flows, discount rates reflecting the market rate of return, projected growth rates and determination and evaluation of appropriate market comparables. Based on the results of quantitative assessments of all reporting units, the Corporation concluded that no impairment existed at December 31, 2013. However, future events could cause the Corporation to conclude that goodwill or other intangibles have become impaired, which would result in recording an impairment loss. Any resulting impairment loss could have a material adverse impact on the Corporation’s financial condition and results of operations.

Income Taxes

The Corporation files a consolidated federal income tax return. The provision for federal and state income taxes is based on income reported on the consolidated financial statements, rather than the amounts reported on the respective income tax returns. Deferred tax assets and liabilities are computed using tax rates expected to apply to taxable income in the years in which those assets and liabilities are expected to be realized. The effect on deferred tax assets and liabilities resulting from a change in tax rates is recognized as income or expense in the period that the change in tax rates is enacted.

The Corporation makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain deferred tax assets and liabilities. Significant changes to these estimates may result in an increase or decrease to the Corporation’s tax provision in a subsequent period. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense.

The Corporation assesses the likelihood that it will be able to recover its deferred tax assets. If recovery is not likely, the Corporation will increase its provision for income taxes by recording a valuation allowance against the deferred tax assets that are unlikely to be recovered. The Corporation believes that it will ultimately recover a substantial majority of the deferred tax assets recorded on the balance sheet. However, should there be a change in the Corporation’s ability to recover its deferred tax assets, the effect of this change would be recorded through the provision for income taxes in the period during which such change occurs.

The Corporation periodically reviews the tax positions it takes on its tax return and applies a more likely than not recognition threshold for all tax positions that are uncertain. The amount recognized in the financial statements is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the more likely than not test, no tax benefit is recorded.

Advertising and Promotional Costs

Advertising and promotional costs are generally expensed as incurred.

Per Share Amounts

Earnings per common share is computed using net income available to common stockholders, which is net income adjusted for preferred stock dividends.

Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding net of unvested shares of restricted stock.

Diluted earnings per common share is calculated by dividing net income available to common stockholders adjusted for interest expense on convertible debt by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options, warrants and restricted shares, as calculated using the treasury stock method. Adjustments to net income available to common stockholders and the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share.

Pension Plans

The Corporation sponsors pension plans for its employees. The expense associated with the plans is calculated in accordance with ASC 715, Compensation – Retirement Benefits. The plans utilize assumptions and methods determined in accordance with ASC 715, including reflecting trust assets at their fair value for the qualified pension plans and recognizing the overfunded and underfunded status of the plans on its consolidated balance sheet. Gains and losses, prior service costs and credits are recognized in accumulated other comprehensive income, net of tax, until they are amortized, or immediately upon curtailment.

Stock Based Compensation

The Corporation accounts for its stock based compensation awards in accordance with ASC 718, Compensation – Stock Compensation, which requires the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards, including stock options and restricted stock, made to employees and directors.

ASC 718 requires companies to estimate the fair value of share-based awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Corporation’s consolidated statement of income over the shorter of requisite service periods or the period through the date that the employee first becomes eligible to retire. Because share-based compensation expense is based on awards that are ultimately expected to vest, share-based compensation expense has been reduced to account for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
