Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations First NBC Bank Holding Company (Company) is a bank holding company that offers a broad range of financial services through First NBC Bank (Bank), a Louisiana state non-member bank, to businesses, institutions, and individuals in southeastern Louisiana and the Florida panhandle. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States and to prevailing practices within the banking industry. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and First NBC Bank, and First NBC Bank’s wholly owned subsidiaries, which include First NBC Community Development, LLC (FNBC CDC), First NBC Community Development Fund, LLC (FNBC CDE) (collectively referred to as the Bank) and any variable interest entities of which the Company is the primary beneficiary. Substantially all of the Variable Interest Entities (VIE) for which the Company is the primary beneficiary relate to tax credit investments. FNBC CDC is a Community Development Corporation formed to construct, purchase, and renovate affordable residential real estate properties in the New Orleans area. FNBC CDE is a Community Development Entity (CDE) formed to apply for and receive allocations of Federal New Markets Tax Credits (NMTC). Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are susceptible to a significant change in the near term are the allowance for loan losses, income tax provision, fair value adjustments, impairment on tax credit investments, and share-based compensation. Concentration of Credit Risk The Company’s loan portfolio consists of the various types of loans described in Note 8. Real estate or other assets secure most loans. The majority of these loans have been made to individuals and businesses in the Company’s market area of southeastern Louisiana and the Florida panhandle, which are dependent on the area economy for their livelihoods and servicing of their loan obligations. The Company does not have any significant concentrations to any one industry or customer. The Company maintains deposits in other financial institutions that may, from time to time, exceed the federally insured deposit limits. Business Combinations Assets and liabilities acquired in business combinations are recorded at their acquisition date fair values. In accordance with ASC Topic 805, Business Combinations, the Company generally records provisional amounts at the time of acquisition based on the information available to the Company. The provisional estimates of fair values may be adjusted for a period of up to one year (“measurement period”) from the date of acquisition if new information obtained about facts and circumstances that existed as of the acquisition date, if known, would have affected the measurement of the amounts recognized as of that date. Loans generally represent a significant portion of the assets acquired in the Company’s business acquisitions. If the Company discovers that it has materially underestimated the credit losses expected in the loan portfolio based on information available at the acquisition date within the measurement period, it will reduce or eliminate the gain and/or increase goodwill recorded on the acquisition in the period the adjustment is recorded. If the Company determines that losses arose subsequent to acquisition date, such losses are reflected as a provision for credit losses. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include the amount in the accompanying consolidated balance sheet caption, cash and cash equivalents, which represents cash on hand, balances due from other financial institutions, and federal funds sold with original maturities less than three months. Investment Securities Investment securities are classified either as held to maturity or available for sale. Management determines the classification of securities when they are purchased. Investment securities that the Company has the ability and positive intent to hold to maturity are classified as securities held to maturity and are stated at amortized cost. The amortized cost of debt securities classified as held to maturity or available for sale is adjusted for amortization of premiums and accretion of discounts over the contractual life of the security using the effective interest method or, in the case of mortgage-backed securities, over the estimated life of the security using the effective yield method. Such amortization or accretion is included in interest income on securities. Securities that may be sold in response to changes in interest rates, liquidity needs, or asset liability management strategies are classified as securities available for sale. These securities are carried at fair value, with net unrealized gains or losses excluded from earnings and shown as a separate component of shareholders’ equity in accumulated other comprehensive income (loss), net of income taxes. Any expected credit loss due to the inability to collect all amounts due accordingly to the security’s contractual terms is recognized as a charge against earnings. Any remaining unrealized loss related to other factors is recognized in other comprehensive income (loss), net of taxes. Realized gains and losses on both held to maturity securities and available for sale securities are computed based on the specific-identification method. Realized gains and losses and declines in value judged to be other than temporary are included in net investment securities gains and losses. Unrealized losses on securities are evaluated to determine if the losses are temporary, based on various factors, including the cause of the loss, prospects for recovery, projected cash flows, collateral values, credit enhancements and other relevant factors, and management’s intent and ability not to sell the security until the fair value exceeds amortized cost. A charge is recognized against earnings for all or a portion of the impairment if the loss is determined to be other than temporary. Investment in Short-Term Receivables The Company invests in short-term receivables which are purchased on an exchange. These short-term receivables have repayment terms of less than a year. The investments are recorded at cost plus accreted discount. The Company evaluates its investments in short-term receivables for impairment once they become delinquent. Mortgage Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value, in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Loans held for sale have primarily been fixed-rate, single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within 120 days. These loans are sold with the mortgage servicing rights released. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances which may include early payment default, breach of representations or warranties, and documentation deficiencies. During 2015 and 2014 , an insignificant number of loans were returned to the Company. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered or in the case of a loan participation, a portion of the asset has been surrendered and meets the definition of a "participating interest". Control over transferred assets is deemed to be surrendered when 1) the assets have been isolated from the Company, 2) the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets, and 3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Should the transfer not meet these three criteria, the transaction is treated as a secured financing. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the principal amount outstanding, net of unamortized fees and costs on originated loans and allowances for loan losses. Loan origination fees and certain direct loan origination costs are deferred and amortized over the lives of the respective loans as a yield adjustment using the effective interest method. Interest income on loans is accrued as earned using the interest method over the life of the loan. Interest on loans deemed uncollectible is excluded from income. The accrual of interest is discontinued and reversed against current income once loans become more than 90 days past due or earlier if conditions warrant. The past due status of loans is determined based on the contractual terms. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status, interest accrued and unpaid during prior periods is reversed. Generally, any payments on nonaccrual loans are applied first to outstanding loan principal amounts and then to the recovery of the charged-off loan amounts. Any excess is treated as recovery of lost interest and fees. Loans are returned to accrual status after a minimum of six consecutive monthly payments have been made in a timely manner. The Company considers a loan to be impaired when, based upon current information and events, it believes it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. The Company’s impaired loans include troubled debt restructurings (TDRs) and performing and nonperforming loans for which full payment of principal or interest is not expected. The Company calculates a reserve required for impaired loans based on the present value of expected future cash flows discounted using the loan’s effective interest rate or the fair value of the collateral securing the loan. Third-party property valuations are obtained at the time of origination for real estate-secured loans. The Company obtains updated appraisals on all impaired loans at least annually. In addition, if an intervening event occurs that, in management’s opinion, would suggest further deterioration in value, the Company obtains an updated appraisal. These policies do not vary based on loan type. Any exposure arising from the deterioration in value of collateral evidenced by the appraisal is recorded as an adjustment to the loan loss reserve in the case of an impaired loan or as an adjustment to income in the case of foreclosed property. Troubled Debt Restructurings The Company periodically grants concessions to its customers in an attempt to protect as much of its investment as possible and minimize the risk of loss. These concessions may include restructuring the terms of a customer loan, thereby adjusting the customer’s payment requirements. In order to be considered a TDR, the Company must conclude that the restructuring constitutes a concession and the customer is experiencing financial difficulties. The Company defines a concession to a customer as a modification of existing loan terms for economic or legal reasons that it would otherwise not consider. Concessions are typically granted through an agreement with the customer or are imposed by a court of law. Concessions include modifying original loan terms to reduce or defer cash payments required as part of the loan agreement, including but not limited to: • A reduction of the stated interest rate for the remaining original life of the debt; • Extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk characteristics; • Reduction of the face amount or maturity amount of the debt as stated in the agreement; or • Reduction of accrued interest receivable on the debt. In its determination of whether the customer is experiencing financial difficulties, the Company considers numerous indicators, including but not limited to: • Whether the customer is currently in default on its existing loan or is in an economic position where it is probable the customer will be in default on its loan in the foreseeable future without a modification; • Whether the customer has declared or is in the process of declaring bankruptcy; • Whether there is substantial doubt about the customer’s ability to continue as a going concern; • Whether, based on its projections of the customer’s current capabilities, the Company believes the customer’s future cash flows will be insufficient to service the debt, including interest, in accordance with the contractual terms of the existing agreement for the foreseeable future; or • Whether, without modification, the customer cannot obtain sufficient funds from other sources at an effective interest rate equal to the current market rate for similar debt for a nontroubled debtor. If the Company concludes that both a concession has been granted and the concession was granted to a customer experiencing financial difficulties, the Company identifies the loan as a TDR. For purposes of the determination of an allowance for loan losses on these TDRs, the loan is reviewed for specific impairment in accordance with the Company’s allowance for loan loss methodology. If it is determined that losses are probable on such TDRs, either because of delinquency or other credit quality indicators, the Company establishes specific reserves for these loans. Acquisition Accounting for Loans The Company accounts for business combinations in accordance with Financial Accounting Standards Board (FASB) ASC 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. The fair value of loans that do not have deteriorated credit quality are accounted for in accordance with ASC 310-20, Nonrefundable Fees and Other Costs, and is represented by the expected cash flows from the portfolio discounted at current market rates. In estimating the cash flows, the Company makes assumptions about the amount and timing of principal and interest payments, estimated prepayments, estimated default rates, estimated loss severities in the event of defaults, and current market rates. The fair value adjustment is amortized over the life of the loan using the effective interest method. The Company accounts for certain acquired loans with deteriorated credit quality under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. In accordance with ASC 310-30 and in estimating the fair value of loans with deteriorated credit quality as of the acquisition date, the Company: (a) calculates the contractual amount and timing of undiscounted principal and interest payments (the undiscounted contractual cash flows), and (b) estimates the amount and timing of undiscounted expected principal and interest payments (the undiscounted expected cash flows). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the loans with deteriorated credit quality is the accretable yield. The accretable yield is recorded into interest income over the estimated lives of the loans using the effective yield method. The accretable yield changes over time as actual and expected cash flows vary from the estimated cash flows at acquisition. Decreases in expected cash flows subsequent to acquisition result in recognition of a provision for loan loss. The accretable yield is measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The remaining undiscounted expected cash flows are calculated at each financial reporting date, based on information currently available. Increases in expected cash flows over those originally estimated increase the accretable yield and are recognized prospectively as interest income. Increases in expected cash flows may also lead to the reduction of any allowance for loan losses recorded after the acquisition. Decreases in expected cash flows compared to those originally estimated decrease the accretable yield and are recognized by recording an allowance for loan losses. As the accretable yield increases or decreases from changes in cash flow expectations, the offset is an increase or decrease to the nonaccretable difference. There is no carryover of allowance for loan losses, as the loans acquired are initially recorded at fair value as of the date of acquisition. Allowance for Loan Losses The allowance for loan losses represents an estimate that management believes will be adequate to absorb probable incurred losses on existing loans in its portfolio at the balance sheet date. The allowance is based on an evaluation of the collectability of loans and prior loss experience of the Company. While management uses available information to make loan loss allowance evaluations, adjustments to the allowance may be necessary based on changes in economic and other conditions or changes in accounting guidance. See Note 8 for an analysis of the Company’s allowance for loan losses by portfolio and portfolio segment, and credit quality information by class. Management has an established methodology to determine the allowance for loan losses that assesses the risks and losses inherent in its portfolio and portfolio segments. The Company utilizes an internally developed model that requires significant judgment to determine the estimation method that fits the credit risk characteristics of the loans in its portfolio and portfolio segments. The allowance for loan losses is established through a provision for loan losses charged to expense. A similar methodology and model is utilized by the Company to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in other liabilities. The appropriateness of the allowance for loan losses is determined in accordance with generally accepted accounting principles. The Company’s loan portfolio is disaggregated into portfolio segments for purposes of determining the allowance for loan losses. The Company’s portfolio segments include commercial real estate, consumer real estate, commercial and industrial, and consumer loans. The Company further disaggregates the commercial and consumer real estate portfolio segments into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within each commercial real estate portfolio segment include commercial real estate construction and commercial real estate mortgage. Classes within each consumer real estate portfolio segment include consumer real estate construction and consumer real estate mortgage. Loans are charged off against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The allowance for loan losses consists of specific and general reserves. The Company determines specific reserves based on the provisions of ASC 310, Receivables. The Company’s allowance for loan losses includes a measure of impairment for those loans specifically identified for evaluation under the topic. This measurement is based on a comparison of the recorded investment in the loan with either the expected cash flows discounted using the loan’s original contractual effective interest rate or the fair value of the collateral underlying certain collateral-dependent loans. Collectability of principal and interest is evaluated in assessing the need for a loss accrual. Loans identified as impaired are individually evaluated periodically for impairment. General reserves are based on management’s evaluation of many factors and reflect an estimated measurement of losses related to loans not individually evaluated for impairment. These loans are grouped into portfolio segments. The loss rates are derived from historical loss factors of the Company sustained on loans according to their risk grade, as well as qualitative and economic factors, and may be adjusted for Company-specific factors. Loss rates are reviewed quarterly and adjusted as management deems necessary based on changing borrower and/or collateral conditions and actual collections and charge-off experience. The loss emergence period is evaluated and derived from historical data based on the date of the loss event to the actual date of charge-off and the resulting loss emergence period is applied as a factor against the historical loss factor which is reviewed annually. Based on observations made through a qualitative review, management may apply qualitative adjustments to the quantitatively determined loss estimates at a group and/or portfolio segment level as deemed appropriate. Primary qualitative and environmental factors that may not be directly reflected in quantitative estimates include: • Asset quality trends; • Changes in lending policies; • Trends in the nature and volume of the loan portfolio, including the existence and effect of any portfolio concentrations; • Changes in experience and depth of lending staff; and • National and regional economic trends. Changes in these factors are considered in determining the directional consistency of changes in the allowance for loan losses. The impact of these factors on the Company’s qualitative assessment of the allowance for loan losses can change from period to period based on management’s assessment to the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for loan losses. Off-Balance-Sheet Credit-Related Financial Instruments The Company accounts for its guarantees in accordance with the provisions of ASC 460, Guarantees. In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card agreements, and standby letters of credit. Such financial instruments are recorded when they are funded. Premises and Equipment Land is carried at cost. Buildings, furniture, fixtures, and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated life of each respective type of asset as follows: Buildings 40 years Furniture, fixtures, and equipment 5 - 15 years Leasehold improvements are amortized using the straight-line method over the periods of the leases, including options expected to be exercised, or the estimated useful lives, whichever is shorter. Gains and losses on disposition and maintenance and repairs are included in current operations. Rental expense on leased property is recognized on a straight-line basis over the original lease term plus options that management expects to exercise. Fixed rental increases that are determinable are expensed over the lease period, including any option periods which are expected to be exercised, using a straight-line lease expense method. Other Real Estate Assets acquired through, or in lieu of, loan foreclosure are held for sale and are recorded at a new cost basis determined at the date of foreclosure as the lower of cost or fair value less estimated cost to sell. Cost is defined as the recorded investment in the loan. Subsequent to foreclosure, valuation allowances are established for any decreases in the estimate of the asset’s fair value or selling costs. Revenues and expenses from operations and changes in the valuation allowance are included in current earnings. Goodwill and Other Intangible Assets Goodwill Goodwill represents the excess of the consideration paid in a business combination over the fair value of the identifiable net assets acquired. Goodwill is not amortized, but is assessed for potential impairment at a reporting unit level on an annual basis, on October 1, or whenever events or changes in circumstances indicate that it is more likely than not the fair value of a reporting unit is less than its respective carrying amount. As part of its testing, the Company may elect to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the results of the qualitative assessment indicate that more likely than not a reporting unit’s fair value is less than its carrying amount, the Company determines the fair value of the respective reporting unit (through the application of various quantitative valuation methodologies) relative to its carrying amount to determine whether quantitative indicators of potential impairment are present (i.e., Step 1). The Company may also elect to bypass the qualitative assessment and begin with Step 1. If the results of Step 1 indicate that the fair value of the reporting unit may be below its carrying amount, the Company determines the fair value of the reporting unit’s assets and liabilities, considering deferred taxes, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill (i.e., Step 2). Intangible assets subject to amortization The Company’s acquired intangible assets that are subject to amortization include core deposit intangibles and are amortized on a straight-line basis over their estimated useful lives and evaluated annually for impairment. Investments in Real Estate Properties FNBC CDC invests in real estate properties, which are carried at cost. Costs of construction are capitalized during the construction period and do not include interest. The Company periodically obtains as-is appraisals to determine the recoverability of its investments for which it intends to sell. For properties the Company intends to hold, the Company assesses recoverability based on the cash flows of the underlying properties. Investments in Tax Credit Entities, net As part of its Community Reinvestment Act responsibilities and due to their favorable economics, the Company invests in tax credit-motivated projects. These projects produce tax credits issued under Federal Low-Income Housing, Federal Historic Rehabilitation, and Federal New Markets Tax Credits (Federal NMTC) programs. The Company generates its returns on tax credit motivated projects through the receipt of federal, and if applicable, state tax credits as well as equity returns. The federal tax credits are recorded as an offset to the income tax provision in the year that they are earned under federal income tax law – over 10 to 15 years, beginning in the year in which rental activity commences for Federal Low-Income Housing credits, in the year of the issuance of the certificate of occupancy and the property being placed into service for Federal Historic Rehabilitation credits, and over 7 years for Federal NMTC upon the investment of funds into the CDE. These credits, if not used in the tax return for the year of origination, can be carried forward for 20 years. The state credits are recorded in income when earned (usually when the project is placed in service) and sold to investors since the Company pays minimal state income taxes under Louisiana tax law. The Company invests in projects generating Federal Low-Income Housing credits, by investing in a tax credit entity, usually a limited liability company, which owns the real estate. The Company receives a 99.99% nonvoting interest in the entity that must be retained during the compliance period for the credits ( 15 years). Control of the tax credit entity rests in the .01% interest general partner, who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. The Company accounts for its investment in Federal Low-Income Housing credits utilizing the equity method of accounting. The Company begins to evaluate its investment for impairment at the time the tax credits are earned through the end of the 15 year compliance period. The Company evaluates its investment at the end of each reporting period for impairment and any residual returns are expected to be minor. For Federal Historic Rehabilitation credits, the Company invests in a tax credit entity, usually a limited liability company, which owns the real estate or a master tenant structure. In some cases, the Company receives a 99% nonvoting interest in the tax credit entity that must be retained during the compliance period for the credits ( 5 years). In some instances, the Company invests 99% in a pass through entity called a master tenant, which maintains an ownership interest in a limited liability company which owns the real estate. In most cases, the Company’s interest in the entity (in either structure) is generally reduced from a 99% interest to a 0% to 25% interest at the end of the compliance period. Control of the tax credit entity rests in the 1% interest general partner (in either structure), who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. The Company accounts for its investment in Federal Historic Rehabilitation credits utilizing the equity method of accounting. The Company begins to evaluate its investment for impairment at the time the credit is earned, which is typically in the year the project is placed in service, through the end of its compliance period. The Company evaluates its investment at the end of each reporting period for impairment and any expected residual returns reduce the amount of impairment recognized. For Federal NMTC, a different structure is required by federal tax law. In order to distribute Federal NMTC, the federal government allocates such credits to CDEs. The Company invests in both CDEs formed by unaffiliated parties and in CDEs formed by the Company. Projects must be commercial or real estate operations and are qualified by their location in low- income areas or by their employment of, or service to, low-income citizens. A CDE, in most cases, creates a special-purpose subsidiary for each project through which the credits are allocated and through which the proceeds from the tax credit investor and a leverage lender, if applicable, flow through to the project, which in turn generate the credit. The credits are calculated at 39% of the total CDE allocation to the project at the rate of 5% for the first three years and 6% for the next four years. Federal tax law requires special terms benefiting the qualified project, which can include below-market interest rates. The Company evaluates its investment for impairment under the equity method of accounting at the end of each reporting period, beginning at the time the tax credits are earned on the project through the end of the seven-year compliance period, and any residual returns are expected to be minor. When the Company also has a loan to the project, it is reported as a loan in the consolidated balance sheet, as the Company has credit exposure to the project and the loan is repaid at the end of the compliance period. In general, the debt has no principal payments during the compliance period but the Company may require the project to fund a sinking fund over the compliance period to achieve the same risk reduction effect as if principal is being amortized. When the Company is the tax credit investor in a CDE formed by an unaffiliated party, it has no control of the applicable CDE or the CDE’s special-purpose subsidiary. For projects which are funded through FNBC CDE, the Company consolidates its CDE and the specifically formed special-purpose entities since it maintains control over these entities; however, the Company does not have control over the enti

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Financial Statements	Restatement of Previously Issued Financial Statements As summarized in the tables below (and the unaudited quarterly financial information in Note 33), prior period financial statements have been restated to correct for the following accounting errors: • Use of an inappropriate amortization method in accounting for the Company’s various investments in tax credit partnerships, as opposed to proper application of the equity method of accounting. These adjustments also include recognition of additional impairments to certain investments in Federal and State Historic Rehabilitation Tax Credit entities based on information available at the time the related financial statements were issued. • Consolidation of certain investments in Federal Low-Income Housing Tax Credit entities because such entities were determined to be variable interest entities in which the Company was the primary beneficiary. The result of the consolidation was an adjustment to decrease loans, increase investments in real estate properties, and adjust the related operating results of these entities in the consolidated financial statements (including removing the impact of the erroneous historical accounting). • Various other adjustments (e.g., state tax credit timing errors). • Income tax effects related to the above adjustments. These errors were identified through evaluations in 2015 of the appropriateness of the Company’s prior amortized cost method used to account for investments in these tax credit entities, more detailed analyses of potential impairments given information that was available at the time the prior period statements were issued, and a reconsideration of the investments in the Company's variable interest entities. The restatements cover the periods from 2013 through September 30, 2015, the last date through which financial statements previously had been issued. The following is a summary of the overall impact of the errors on prior years: For the Years Ended December 31, (In thousands) 2014 2013 Net income, as previously reported $ 55,589 $ 40,911 Correction to equity-method and recognition of impairment (11,008 ) (4,460 ) Consolidation of certain investments (4,562 ) (5,152 ) Other corrections (1,259 ) (1,329 ) (16,829 ) (10,941 ) Tax-effect of corrections 5,747 3,656 Total adjustments, net (11,082 ) (7,285 ) Net income, as restated $ 44,507 $ 33,626 As of December 31, (In thousands) 2014 2013 2012 Accumulated earnings, as previously reported $ 155,599 $ 100,389 $ 59,825 Prior year restatement adjustments, net (16,759 ) (9,474 ) (5,242 ) Correction to equity-method and recognition of impairment (11,008 ) (4,460 ) 463 Consolidation of certain investments (4,562 ) (5,152 ) (5,216 ) Other corrections (1,259 ) (1,329 ) (578 ) (33,588 ) (20,415 ) (10,573 ) Tax-effect of corrections 5,747 3,656 1,099 Total adjustments, net (27,841 ) (16,759 ) (9,474 ) Accumulated earnings, as restated $ 127,758 $ 83,630 $ 50,351 The following tables summarize, by line item, the impacts of the restatement to the Company’s prior period consolidated balance sheets, statements of income, and statements of cash flows as included in these audited financial statements.

Acquisition Activity	Acquisition Activity Acquisition of Certain Assets and Liabilities of First National Bank of Crestview On January 16, 2015, the Company acquired certain assets and assumed certain liabilities from the Federal Deposit Insurance Corporation (FDIC), as receiver for First National Bank of Crestview, a full-service commercial bank headquartered in Crestview, Florida, which was closed and placed into receivership. Under the terms of the agreement, the Company agreed to assume all of the deposit liabilities, and acquire approximately $62.3 million of assets, of the failed bank. The acquired assets included the failed bank's performing loans, substantially all of its investment securities portfolio, and its three banking facilities, with the FDIC retaining the remaining assets. The transaction did not include a loss-share agreement with the FDIC. The Company received a settlement amount from the FDIC of $10.0 million and recorded goodwill of $1.2 million , as shown in the table below. With this acquisition, the Company expanded into the Florida Panhandle market through the addition of the three banking locations and an experienced in-market team that enhances the Company's ability to compete in that market. (In thousands) Total consideration received $ 10,035 Fair value of assets acquired, including identifiable intangible assets 61,088 Fair value of liabilities assumed 72,314 Goodwill $ 1,191 Acquisition of State Investors Bancorp, Inc. On November 30, 2015, the Company acquired State Investors Bancorp, Inc. (SIBC), the parent company for State-Investors Bank, which conducted business from four full service banking offices in the New Orleans metropolitan area. Under the terms of the agreement, each share of SIBC common stock was converted into cash in the amount of $21.51 per share and each issued and outstanding option to purchase a share of SIBC common stock, including any unvested option, which became fully vested in connection with the completion of the merger, was canceled and converted into cash in an amount equal to the difference between $21.51 and the exercise price of the stock option. The Company acquired all of the outstanding common stock of the former SIBC shareholders for a total consideration of $48.7 million , which resulted in goodwill of $8.6 million , as shown in the table below. With this acquisition, the Company expanded its presence in the New Orleans metropolitan area which enhances its ability to compete in that market. The Company projects cost savings will be recognized in future periods through the elimination of redundant operations. (In thousands) Total consideration paid $ 48,744 Fair value of assets acquired, including identifiable intangible assets 254,080 Fair value of liabilities assumed 213,981 Goodwill $ 8,645 The Company incurred merger and acquisition costs of $1.2 million during 2015 for the two acquisitions discussed above. The amount of revenue and earnings for the acquired entities for the years ended December 31, 2015 and December 31, 2014 were not material and therefore not presented herein. The acquired assets and liabilities, as well as the adjustments to record the assets and liabilities at their estimated fair values, are presented in the following tables: First National Bank of Crestview (In thousands) As Acquired Preliminary Fair Value Adjustments As recorded by First NBC Bank Assets Cash and due from banks $ 1,511 $ — $ 1,511 Short-term investments 19,971 — 19,971 Investment securities-available for sale 9,559 — 9,559 Loans 27,647 (1,203 ) (1) 26,444 Bank premises 3,120 — 3,120 Core deposit intangible — 188 (2) 188 Other assets 455 (160 ) 295 Total Assets $ 62,263 $ (1,175 ) $ 61,088 Liabilities Deposits: Noninterest-bearing $ 22,680 $ — $ 22,680 Interest-bearing 49,584 16 (3) 49,600 Total deposits 72,264 16 72,280 Other liabilities 34 — 34 Total Liabilities $ 72,298 $ 16 $ 72,314 Explanation of certain fair value adjustments: (1) The amount represents the adjustment of the book value of First National Bank of Crestview's loans to their estimated fair value based on current interest rates and expected cash flows, which includes estimates of expected credit losses inherent in the portfolio. (2) The amount represents the estimated fair value of the core deposit intangible asset created in the acquisition. The core deposit intangible asset will be amortized over the estimated useful life of 12 years. (3) The adjustment is necessary because the weighted-average interest rate of First National Bank of Crestview's deposits exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce future interest expense over the expected life of the deposits, which is estimated at 49 months. State Investors Bancorp, Inc.

(2) The amount represents the adjustment of the book value of loans acquired to their estimated fair value based on current interest rates and expected cash flows, which includes estimates of expected credit losses inherent in the portfolio. (3) The amount represents the adjustment of the book value of SIBC's bank premises and equipment to their estimated fair value at the acquisition date based on their appraised value on the date of acquisition. (4) The amount represents the deferred tax asset recognized on the fair value adjustment of SIBC acquired assets and assumed liabilities. (5) The amount represents the estimated fair value of the core deposit intangible asset created in the acquisition. The core deposit intangible asset will be amortized over the estimated useful life of 12 years. (6) The adjustment is necessary because the weighted-average interest rate of SIBC's deposits exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce future interest expense over the life of the deposits. (7) The adjustment represents the adjustment of the book value of SIBC's borrowings to their estimated fair value based on current interest rates and the credit characteristics inherent in the liability.

Management determined that it has both the positive intent and ability to hold these securities until maturity. The reclassified securities consisted of municipal and mortgage-backed securities and were transferred due to movements in interest rates. The securities were reclassified at fair value at the time of the transfer and represented a non-cash transaction. Accumulated other comprehensive income (loss) included pre-tax unrealized losses of $5.9 million on these securities at the date of the transfer. As of December 31, 2015 , $4.5 million of pre-tax unrealized losses on these securities were included in accumulated other comprehensive income. These unrealized losses and offsetting other comprehensive income components are being amortized into net interest income over the remaining life of the related securities as a yield adjustment, resulting in no impact on future net income. At December 31, 2015 , the Company’s exposure to three investment security issuers individually exceeded 10% of shareholders’ equity: (In thousands) Amortized Cost Estimated Market Value Federal National Mortgage Association (Fannie Mae) $ 85,511 $ 84,519 Federal Home Loan Bank (FHLB) 64,313 64,073 Federal Home Loan Mortgage Corporation (Freddie Mac) 54,901 52,797 $ 204,725 $ 201,389 As of December 31, 2015 , the Company had 205 securities that were in a loss position. The unrealized losses for each of the 205 securities relate to market interest rate changes. The Company has considered the current market for the securities in a loss position, as well as the severity and duration of the impairments, and expects that the value will recover. As of December 31, 2015 , management does not intend to sell these investments until the fair value exceeds amortized cost and it is more likely than not that the Company will not be required to sell debt securities before the anticipated recovery of the amortized cost basis of the security; thus, the impairment is determined not to be other-than-temporary. As of December 31, 2014 , the Company had 38 securities that were in a loss position. The unrealized losses for each of the 38 securities relate to market interest rate changes. The Company has considered the current market for the securities in a loss position, as well as the severity and duration of the impairments, and expects that the value will recover. As of December 31, 2014 , management had both the intent and ability to hold these investments until the fair value exceeds amortized cost; thus, the impairment is determined not to be other-than-temporary. In addition, management does not believe the Company will be required to sell debt securities before the anticipated recovery of the amortized cost basis of the security. The amortized cost and estimated market values by contractual maturity of investment securities as of December 31, 2015 and December 31, 2014 are shown in the following table.

There were gross losses of $0.6 and $0.2 realized for the years ended December 31, 2014 and 2013 , respectively. The Company sold a municipal security that was classified as held to maturity in 2014.

Investments, All Other Investments [Abstract]
Investments in Tax Credit Entities	Investments in Tax Credit Entities Federal NMTC Investment in Bank Owned CDE The Bank owns a CDE which competes each year for a Federal New Markets Tax Credits allocation. The Federal NMTC program is administered by the Community Development Financial Institutions Fund of the U.S. Treasury and is aimed at stimulating economic and community development and job creation in low-income communities. The program provides federal tax credits to investors who make qualified equity investments (QEIs) in a CDE. The CDE is required to invest the proceeds of each QEI in projects located in or benefiting low-income communities, which are generally defined as those census tracts with poverty rates greater than 20% and/or median family incomes that are less than or equal to 80% of the area median family income. FNBC CDE has received allocations of Federal NMTC totaling $118.0 million since 2011. These allocations generated $46.0 million in tax credits. The credit provided to the investor totals 39% of each QEI in a CDE and is claimed over a seven -year credit allowance period. In each of the first three years, the investor receives a credit equal to 5% of the total QEI allocated to the project. For each of the remaining four years, the investor receives a credit equal to 6% of the total QEI allocated to the project. The Company has received up to $46.0 million in tax credits over the seven -year credit allowance period, beginning with the period in which the QEI was made, for its QEI of $118.0 million . Through December 31, 2015 , FNBC CDE has invested in allocations of $118.0 million , of which $40.0 million of the awards was invested by the Company and $78.0 million was invested by other investors and leverage lenders, which include the Company. Of the $78.0 million invested by other investors and leverage lenders, $17.5 million was invested by the Company as the leverage lender. The Company's investment in its subsidiary CDE is eliminated upon consolidation. While the leverage lender's portion of the investment in the CDE is classified as a loan, the remaining investment in the CDE is accounted for as an equity method investment included in investment in tax credit entities in the accompanying consolidated balance sheets and evaluated at each reporting date for impairment. The impairment is evaluated based on the remaining tax credits available along with any applicable equity income or loss allocations. Impairment, if any, is recorded in the consolidated statement of income as a component of noninterest expense as well as any applicable equity income or loss allocations. The Federal NMTC claimed by the Company, with respect to each QEI, remain subject to recapture over each QEI’s credit allowance period upon the occurrence of any of the following: • CDE does not invest substantially all (defined as a minimum of 85% ) of the QEI proceeds in qualified low-income community investments; • CDE ceases to be a CDE; or • CDE redeems its QEI investment prior to the end of the current credit allowance period. At December 31, 2015 and 2014, none of the above recapture events had occurred, nor, in the opinion of management, are such events anticipated to occur in the foreseeable future. As of December 31, 2015 , FNBC CDE had total assets of $131.6 million , consisting of cash of $6.6 million , loans of $112.3 million and other assets of $12.7 million , with liabilities of $0.5 million and capital of $131.1 million . Based on the structure of these transactions, the Company expects to recover its investment solely through use of the tax credits that were generated by the investments and any equity returns received through the limited partnership. Investments in Non-Bank Owned CDEs The Company is also a limited partner in several tax-advantaged limited partnerships and a shareholder in several C corporations whose purpose is to invest in approved Federal NMTC projects through CDEs that are not associated with FNBC CDE. During 2014, several of these partnerships that the Company was a limited partner in converted to C corporations. The Company’s ownership in the CDEs did not change based on the conversion. These investments are accounted for using the equity method of accounting and are included in investment in tax credit entities in the accompanying consolidated balance sheets. The limited partnerships and C corporations are considered VIEs. The VIEs have not been consolidated because the Company is not considered the primary beneficiary. The Company's investment in Federal NMTC partnerships and C corporations, net of the loans to the investment fund, are evaluated for impairment at the end of each reporting period based on the remaining tax credits available along with any equity income or loss allocations. Impairment, if any, is recorded in the consolidated statement of income as a component of noninterest expense as well as any applicable equity income or loss allocations. All of the Company’s investments in Federal NMTC structures are privately held, and their market values are not readily determinable. Based on the structure of these transactions, the Company expects to recover its investment solely through use of the tax credits that were generated by the investments and any equity returns received through the limited partnership. Federal Low-Income Housing Tax Credits The Company is a limited partner in tax-advantaged limited partnerships whose purpose is to invest in approved Federal Low-Income Housing tax credit projects. The tax credits associated with these investments are typically received over a 10 to 15 year period subject to recapture. These investments are accounted for using the equity method of accounting and are included in investments in tax credit entities in the accompanying consolidated balance sheets. The limited partnerships are considered to be VIEs and are evaluated for consolidation based on the Company's determination if it is the primary beneficiary. The Company has determined that it is not the primary beneficiary with respect to the limited partnerships. Thus, the VIEs have not been consolidated except for three Federal Low-Income Housing investments which were consolidated (See Note 15 for further details.) The Company utilizes the effective yield method to evaluate impairment. Impairment, if any, is recorded in the consolidated statement of income as a component of noninterest expense as well as any applicable equity income or loss allocations. All of the Company’s investments in Federal Low-Income Housing partnerships are evaluated for impairment at the end of each reporting period. Based on the structure of these transactions, the Company expects to recover its remaining investments at December 31, 2015 through the use of the tax credits that were generated by the investments and any equity returns received through the limited partnerships. Federal Historic Rehabilitation Tax Credits The Company is a limited partner in several tax-advantaged limited partnerships whose purpose is to invest in approved Federal Historic Rehabilitation tax credit projects. The tax credits generated on these investments are received in the year that the project is placed in service and subject to recapture over a 5 year period. These investments are accounted for using the equity method of accounting and are included in investments in tax credit entities in the accompanying consolidated balance sheets. The limited partnerships are considered to be VIEs and are evaluated for consolidation based on the Company's determination if it is the primary beneficiary. The Company has determined that it is not the primary beneficiary with respect to any of the limited partnerships and, thus, the VIEs have not been consolidated. All of the Company’s investments in limited partnerships are evaluated for impairment at the end of each reporting period and the Company records impairment, if any, in its consolidated statement of income as a component of noninterest expense. Impairment is calculated based upon future cash flows to be received during the Company's ownership period and the residual amount expected to be received upon disposition of its ownership position. Based on the structure of these transactions, the Company expects to recover its remaining investments in Federal Historic Rehabilitation tax credits at December 31, 2015 through the future cash flows and equity ownership in the underlying projects. State Historic Rehabilitation Tax Credits In connection with its limited partner interest in several tax-advantaged limited partnerships whose purpose is to invest in approved Federal Historic Rehabilitation tax credit projects, the Company can receive Louisiana State Historic Rehabilitation tax credits. These credits are certified by the State of Louisiana and are earned by the Company once the project is placed in service and then sold to investors after the State Historic Rehabilitation tax credits are certified by the State of Louisiana and transferred from the project to the Company. The credits are typically sold within 12 months of the project being placed in service. The Company evaluates its investment for impairment at the end of each reporting period. Impairment, if any, is recorded in its consolidated statement of income as a component of noninterest expense. State NMTC Investments in Non-Bank Owned CDEs The Company is a limited partner in several tax-advantaged limited partnerships that are CDEs, whose purpose is to invest in approved State NMTC projects that are not associated with FNBC CDE. Based on the structure of these transactions, the Company expects to recover its remaining investments in State NMTC at December 31, 2015 through the transfer of its ownership interest to third party investors. The Company evaluates its investment for impairment at the end of each reporting period. Impairment, if any, is recorded in its consolidated statement of income as a component of noninterest expense. The tables below set forth the Company's investment in Federal and State NMTC, Federal Low-Income Housing, and Federal and State Historic Rehabilitation tax credits, along with the credits earned and expected to be generated through its participation in these programs as of December 31, 2015 and December 31, 2014 .

The Company will receive payments from the counterparty at three-month LIBOR and make payments to the counterparty at fixed rates of 2.652% , 2.753% , and 2.793% , respectively, on each of the $55.0 million notional amounts of the derivative contracts. The cash flow payments on the derivatives begin January 2018 and terminate October 2023 for the 2.652% interest rate swap, begin January 2019 and terminate October 2024 for the 2.753% interest rate swap, and begin July 2019 and terminate April 2025 for the 2.793% interest rate swap. The Company terminated its cash flow hedge with Counterparty A in 2014, which the Company had originally entered into in 2012, as internal forecasts for future interest rates changed since this transaction was initiated. The total notional amount of the derivative contract was $115.0 million and the Company was to receive payments from the counterparty at three-month LIBOR and make payments to the counterparty at a fixed rate on 2.88% on the notional amount. The termination of the cash flow hedge resulted in a loss of $8.0 million which had been reflected in the Company’s operating cash flows and included within accumulated other comprehensive income (loss), net of tax as of December 31, 2015 and 2014 . This loss had not been included in net income as of December 31, 2014 as the Company entered into a new delayed interest rate swap with substantially similar terms (see transaction above with Counterparty C) at the time of termination. The loss will be reclassified from accumulated other comprehensive income (loss) to net income as interest expense as it is amortized over a multi-year period consistent with the original maturity dates of the hedge which began in January 2015 and terminates in January 2022. The Company entered into a delayed interest rate swap with Counterparty B in 2013 to manage exposure against the variability in the expected future cash flows attributed to changes in the benchmark interest rate on a portion of its variable-rate debt. The Company entered into this interest rate swap agreement to convert a portion of its variable-rate debt to a fixed rate, which is a cash flow hedge of a forecasted transaction. The total notional amount of the derivative contract is $150.0 million . The Company will receive payments from the counterparty at three-month LIBOR and make payments to the counterparty at a fixed rate of 4.165% on the notional amount. The cash flow payments on the derivative begin December 2016 and terminate September 2023. Interest Rate-Prime Swaps . During 2015, the Company entered into two interest rate-prime swaps with Counterparty C to manage exposure against the variability in the expected future cash flows on the designated Prime and Prime plus 1% pools of its floating rate loan portfolio. The Company entered into these interest rate-prime swap agreements to hedge the cash flows from these pools of its floating rate loan portfolio, which is expected to offset the variability in the expected future cash flows attributable to the fluctuations in the daily weighted average Wall Street Journal Prime index, which is a cash flow hedge of a forecasted transaction. The notional amount of the contracts are a Prime tranche of $30.0 million and a Prime plus 1% tranche of $40.0 million for a total notional amount of $70.0 million . The Company receives payments from the counterparty at a fixed rate of interest and pays the counterparty at the Prime rate associated with each tranche on its notional amount. The Prime tranche receives payments at a fixed rate of 4.50% and pays the counterparty at Prime on the notional amount. The Prime plus 1% tranche receives payments at a fixed rate of 5.49% and pays the counterparty at Prime plus 1% on the notional amount. The cash flow payments on the derivatives began December 2015 and terminate September 2022. During 2015, the Company terminated two of its interest rate swaps with Counterparty B, which the Company originally entered into in 2013, as internal forecasts for future interest rates changed since these transactions were initiated. The notional amounts of the derivative contracts were a Prime tranche of $30.0 million and a Prime plus 1% tranche of $40.0 million for a total notional amount of $70.0 million . The termination of the cash flow hedges resulted in a gain of $1.3 million which has been reflected in the Company's operating cash flows and included within accumulated other comprehensive income (loss), net of tax. This gain has not been included in net income as of December 31, 2015 as the Company entered into two new interest rate prime swaps with substantially similar terms (see interest rate-prime swaps transaction with Counterparty C above) at the time of termination. The gain will be reclassified from accumulated other comprehensive income (loss) to net income as interest income as it is accreted over a multi-year period consistent with the original maturity dates of the hedges which began in September 2013 and terminates in September 2019. During 2015, the Company entered into four interest rate swaps with Counterparty C to manage exposure against the variability in the expected future cash flows on the designated Prime plus 1% floored at 5% , Prime plus 2% , Prime plus 2% actual/ 365 , and Prime plus 2.25% pools of its floating rate loan portfolio. The Company entered into the interest rate-prime swap agreements to hedge the cash flows from these pools of its floating rate loan portfolio, which is expected to offset the variability in the expected future cash flows attributable to the fluctuations in the daily weighted average Wall Street Journal Prime index, which is a cash flow hedge of a forecasted transaction. The notional amount of the contracts are Prime plus 1% floored at 5% tranche of $40.0 million , Prime plus 2% tranche of $15.0 million , Prime plus 2% actual/ 365 tranche of $10.0 million , and Prime plus 2.25% tranche of $10.0 million for a total notional amount of $75.0 million . The Company receives payments from the counterparty at a fixed rate of interest and pays the counterparty at the Prime rate associated with each tranche on its notional amount. The Prime plus 1% floored at 5% tranche receives payments at a fixed rate of 5.81% and pays the counterparty at Prime plus 1% floored at 5% on the notional amount. The Prime plus 2% and Prime plus 2% actual/ 365 tranches receives payments at a fixed rate of 6.56% and pays the counterparty at Prime plus 2% on the notional amounts. The Prime plus 2.25% tranche receives payments at a fixed rate of 6.81% and pays the counterparty at Prime plus 2.25% on the notional amount. The cash flow payments on the derivatives began March 2015 and terminate March 2021. The Company entered into four interest rate swaps with Counterparty B in 2013 to manage exposure against the variability in the expected future cash flows on the designated Prime, Prime plus 1% , Prime plus 1% floored at 5% and Prime plus 1% floored at 5.5% pools of its floating rate loan portfolio. The Company entered into the interest rate swap agreements to hedge the cash flows from these pools of its floating rate loan portfolio, which is expected to offset the variability in the expected future cash flows attributable to the fluctuations in the daily weighted average Wall Street Journal Prime index, which is a cash flow hedge of a forecasted transaction. The Company terminated the Prime and Prime plus 1% tranches in September 2015 (see September 2015 interest rate-prime swaps transaction with Counterparty B above). The notional amount of the remaining prime hedges are Prime plus 1% floored at 5% tranche of $100.0 million and Prime plus 1% floored at 5.5% tranche of $80.0 million for a total notional amount of $180.0 million as of December 31, 2015 . The Company receives payments from the counterparty at a fixed rate of interest and pays the counterparty at the Prime rate associated with each tranche on its notional amount. The Prime plus 1% floored at 5% tranche receives payments at a fixed rate of 6.01% and pays the counterparty at Prime plus 1% , floored at 5% on the notional amount. The Prime plus 1% floored at 5.5% tranche receives payments at a fixed rate of 6.26% and pays the counterparty at Prime plus 1% floored at 5.5% on the notional amount. The cash flow payments on the derivatives began September 2013 and terminate September 2019.

Net fair values of the Counterparty B and and Counterparty C delayed interest rate swaps and hedges as of December 31, 2015 and 2014 are as follows: December 31, 2015 Gross Amounts Presented in the Balance Sheet Gross Amounts Not Offset in the Balance Sheet (In thousands) Derivatives Collateral Net Derivatives subject to master netting arrangements: Derivative liabilities: Counterparty B $ 16,798 $ — $ — $ 16,798 Counterparty C 2,902 — — 2,902 Net derivative liability $ 19,700 $ — $ — $ 19,700 December 31, 2014 Gross Amounts Presented in the Balance Sheet Gross Amounts Not Offset in the Balance Sheet (In thousands) Derivatives Collateral Net Derivatives subject to master netting arrangements: Derivative liabilities: Counterparty B $ 12,953 $ — $ — $ 12,953 Net derivative liability $ 12,953 $ — $ — $ 12,953 Pursuant to the interest rate swap agreements described above with Counterparty B, the Company pledged collateral in the form of investment securities totaling $19.6 million (with a fair value at December 31, 2015 of $20.0 million ), which has been presented gross in the Company’s balance sheet. Pursuant to the interest rate swap agreements described above with Counterparty C, the Company pledged collateral in the form of investment securities totaling $4.6 million (with a fair value at December 31, 2015 of $4.1 million ), which has been presented gross in the Company’s balance sheet. There was no collateral posted from the counterparties to the Company as of December 31, 2015 and 2014 . Because the swap agreement used to manage interest rate risk has been designated as hedging exposure to variable cash flows of a forecasted transaction, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately. In applying hedge accounting for derivatives, the Company establishes a method for assessing the effectiveness of the hedging derivative by utilizing the dollar offset approach and a measurement approach for determining the ineffective aspect of the hedge through the variable cash flows methods upon the inception of the hedge. These methods are consistent with Company’s approach to managing risk. For interest rate swap agreements that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately. As of December 31, 2015 and 2014, there were no interest rate swap agreements that were not designated as hedging instruments. For the year ended December 31, 2015 , the Company reclassified $1.1 million from accumulated other comprehensive income (loss) into interest expense as a result of the discontinuance of the cash flow hedge with Counterparty A. The Company expcects to reclassify $1.1 million from accumulated other comprehensive income (loss) into interest expense over the next 12 months related to the amortization of the net loss incurred on the cash flow hedge terminated in December 2014. The remaining $6.9 million loss related to the discontinuance of the cash flow hedge with Counterparty A will be reclassified from accumulated other comprehensive income (loss) into interest expense as it is amortized by the effective yield method over a multi-year period consistent with the original maturity dates of the hedge which began in January 2015 and will terminate in January 2022. No amounts were reclassified into earnings for the year ended December 31, 2014 . For the year ended December 31, 2015 , the Company reclassified $0.1 million from accumulated other comprehensive income (loss) into interest income as a result of the discontinuance of the cash flow hedges with Counterparty B. The Company expects to reclassify $0.3 million from accumulated other comprehensive income (loss) into interest income over the next 12 months related to the accretion of the net gain incurred on the cash flow hedges terminated in September 2015. The remaining $1.2 million gain related to the discontinuance of the cash flow hedge with Counterparty B will be reclassified from accumulated other comprehensive income (loss) into interest income as it is accreted by the effective yield method over a multi-year period consistent with the original maturity dates of the hedge which began in September 2013 and terminates in September 2019. As of December 31, 2015 and 2014 , no amounts of gains or losses have been reclassified from accumulated comprehensive income (loss), nor have any amounts of gains or losses been recognized due to ineffectiveness of a portion of the derivatives. At December 31, 2015 , no amount of the derivatives will mature within the next 12 months. The Company does not expect to reclassify any amount from accumulated other comprehensive income (loss) into interest income over the next 12 months for derivatives that will be settled.

Income Taxes	Income Taxes The income tax benefit on the income from operations for the years ended December 31, 2015 , 2014 , and 2013 was as follows: (In thousands) 2015 2014 2013 (Restated) (Restated) Current tax expense $ 2,076 $ 3,436 $ 186 Deferred tax benefit (108,341 ) (36,159 ) (23,593 ) Total tax benefit $ (106,265 ) $ (32,723 ) $ (23,407 ) The amount of taxes in the accompanying consolidated statements of income differs from the expected amount using the statutory federal income tax rates primarily due to the effect of various tax credits. An analysis of those differences for the years ended December 31, 2015 , 2014 , and 2013 are presented below: Year Ended December 31, (In thousands) 2015 2014 2013 (Restated) (Restated) Federal tax (benefit) expense at statutory rates $ (46,026 ) $ 4,125 $ 3,577 Tax credits(1) (61,284 ) (38,445 ) (28,421 ) Tax credit-basis reduction 1,904 1,647 2,019 Other tax credits (616 ) (617 ) — Tax-exempt income (764 ) (87 ) (1,070 ) Disallowed interest expense 76 98 117 Valuation allowance for deferred tax assets 127 143 173 Other 318 413 198 Income tax benefit $ (106,265 ) $ (32,723 ) $ (23,407 ) (1) As discussed in Note 14, the Company earns Federal NMTC, Federal Historic Rehabilitation, and Federal Low-Income Housing tax credits, which reduce the Company’s federal income tax liability or creates a carryforward as applicable. The components of the Company’s deferred tax assets and liabilities as of December 31 are presented below: Year Ended December 31, (In thousands) 2015 2014 (Restated) Deferred tax assets: Loan loss reserve $ 27,467 $ 14,817 Tax credit carryforwards 146,220 91,863 NOL carryforward 8,762 8,681 Stock-based compensation 1,050 824 Deferred compensation 232 91 Securities available for sale 2,635 7,317 Unrealized loss on cash flow hedges 8,879 3,298 Other real estate 297 263 Basis difference in assumed liabilities 2,409 140 Impairment of investment in short term receivables 24,463 — Capital loss carryforward — 309 Other 2,960 884 Gross deferred tax assets 225,374 128,487 Valuation allowance (1,537 ) (1,719 ) Total deferred tax assets 223,837 126,768 Deferred tax liabilities: Fixed assets 7,901 7,190 Deferred loan costs 7,027 6,296 Amortizable costs 1,409 1,388 Investments in tax credit entities 901 17,821 Basis difference in assumed assets 904 — Other 408 558 Total deferred tax liabilities 18,550 33,253 Net deferred tax assets $ 205,287 $ 93,515 In determining whether a valuation allowance related to deferred tax assets was necessary, the Company considered all available evidence including historical information supplemented by all currently available information about future years. The Company also considered events occurring subsequent to December 31, 2015 but before the financial statements were released that provided additional evidence (negative or positive) regarding the likelihood of realization of existing deferred tax assets. The negative evidence cited included cumulative losses in recent years which included all “non-recurring” charges such as impairments or losses on certain assets that had not occurred previously. Certain of these items may not be indicative of future results, but they are part of total results, and therefore similar types of items may occur in future years. Considerable judgment is required in assessing the need for a valuation allowance including all available evidence, both positive and negative, as the assessment includes determining the feasibility and willingness of the Company to employ various tax planning strategies and projections of future taxable income. Management employed various stress test techniques when evaluating the reasonableness of their estimates, including future taxable income, deferring to scenarios deemed to be mostly likely and supportable by the available data. As of December 31, 2015 , the Company’s net operating loss carryforwards were $25.0 million with an expiration date of December 2035 . Included in the Company's net operating loss carryforwards is $19.8 million obtained through a bankrupt entity which the Company's expects to obtain control. As of December 31, 2015 , the Company’s tax credit carryforwards were $146.2 million with expiration dates beginning December 2031 through December 2035 . The Company recognized $16.3 million , $15.5 million , and $14.2 million in Federal NMTC in its consolidated income tax provision for the years ended December 31, 2015 , 2014 , and 2013 , respectively. The Company recognized $4.0 million , $3.6 million , and $3.7 million in Federal Low-Income Housing tax credits in its consolidated income tax provision for the years ended December 31, 2015 , 2014 , and 2013 , respectively. The Company recognized $41.0 million , $19.3 million , and $10.5 million in Federal Historic Rehabilitation tax credits in its consolidated income tax provision for the years ended December 31, 2015 , 2014 , and 2013 , respectively.

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Senior Preferred Stock During 2015, the holder of the Series C preferred stock exchanged 364,983 shares of Series C preferred stock for an equivalent number of shares of common stock. The Company had issued 916,841 shares of convertible perpetual Series C preferred stock in exchange for approximately $20.6 million in 2011.There were no shares of the Company's Series C preferred stock outstanding as of December 31, 2015 . There were no shares of the Company's convertible perpetual preferred stock Series C shares that were converted during 2014, and 551,858 shares of preferred stock were converted into an equivalent number of shares of common stock during 2013. The assumed conversion of the convertible perpetual preferred stock Series C shares outstanding is excluded in the calculation of the Company's diluted earnings per share for the year ended 2014 since the shares were contingently issuable and the contingency still existed as of December 31, 2014. The Company sold approximately $37.9 million of senior noncumulative perpetual preferred stock, Series D in 2011 to the U.S. Treasury, pursuant to the Small Business Lending Fund Program. At December 31, 2015 , the Series D preferred stock had an aggregate liquidation preference of approximately $37.9 million and qualified as Tier 1 regulatory capital. The terms of the Series D preferred stock provide for payment of noncumulative dividends on a quarterly basis beginning October 3, 2011. The dividend rate, as a percentage of the liquidation amount, fluctuates, while the Series D preferred stock is outstanding based upon changes in the level of qualified small business lending (QSBL) by the Company from its average level of QSBL at each of the four quarter-ends leading up to June 30, 2010 (Baseline), as follows: Dividend Period Beginning Ending Annualized Dividend Rate January 1, 2012 March 31, 2012 1.000% April 1, 2012 June 30, 2012 1.000% July 1, 2012 December 31, 2013 1.000% to 5.000% January 1, 2014 February 3, 2016 1.000% to 7.000% February 4, 2016 Redemption 9.000% As long as shares of Series D preferred stock remain outstanding, the Company may not pay dividends to common shareholders (nor may the Company repurchase or redeem any shares of common stock) during any quarter in which the Company fails to declare and pay dividends on the Series D preferred stock and for the next three quarters following such failure. In addition, under the terms of the Series D preferred stock, the Company may only declare and pay dividends on common stock (or repurchase shares of common stock) if, after payment of such dividend, the dollar amount of Tier 1 capital would be at least 90% of Tier 1 capital as of August 4, 2011, excluding charge-offs and redemptions of the Series D preferred stock (Tier 1 dividend threshold). Beginning January 1, 2014, the Tier 1 dividend threshold is subject to a reduction based upon the extent by which, if at all, the QSBL at September 30, 2013, has increased over the Baseline. The Company was notified in 2013 that its dividend rate would be 1% from January 1, 2014 until February 3, 2016 because the Company satisfied the lending baseline at September 30, 2013. The Company may redeem the Series D preferred stock at any time at the Company’s option, at a redemption price of 100% of the liquidation amount plus accrued but unpaid dividends, subject to the approval of the Company’s primary federal regulatory agency. As of February 4, 2016, the Company had not redeemed the Series D preferred stock, and based on its terms, the annual dividend rate increased to 9% .

Capital Requirements and Other

Capital Requirements and Other Regulatory Matters	12 Months Ended
	Dec. 31, 2015
Banking and Thrift [Abstract]
Capital Requirements and Other Regulatory Matters	Capital Requirements and Other Regulatory Matters Regulatory Capital Requirements The Company and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the consolidated financial statements of the Company and the Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets, Tier 1 capital to average assets, and common equity Tier 1 capital to risk-weighted assets. Management believes, as of December 31, 2015 and 2014 , that the Company and the Bank met all minimum capital adequacy requirements to which they are subject. As of December 31, 2015 , the Bank was classified as “adequately capitalized” for purposes of the FDIC's prompt corrective action requirements. To be categorized as "well capitalized", an institution must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 leverage, and common equity Tier 1 capital ratios as set forth in the following table. There are no conditions or events since the notification that management believes have changed that categorization. Section 29 of the Federal Deposit Insurance Act limits the use of brokered deposits by institutions that are less than “well-capitalized” and allows the FDIC to place restrictions on interest rates that institutions may pay.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company has various types of stock-based compensation plans. These plans are administered by the Compensation and Human Resources Committee of the Board of Directors, which selects persons eligible to receive awards and approves the number of shares and/or options subject to each award, the terms, conditions, and other provisions of the awards. Restricted Stock The Company issues restricted stock under the 2006 Plan and 2014 Plan for certain officers and directors. The Company approved the 2014 Plan during May 2014. There were 61,450 restricted stock awards issued under the 2014 Plan during 2015 and 13,021 restricted stock awards issued under the 2014 plan in 2014. Restricted stock awards issued under the 2014 Plan that may not be sold or otherwise transferred until certain restrictions have lapsed. The unearned compensation related to these awards is amortized over the vesting period of 3 years . The total share-based compensation expense related to the awards is determined based on the market price of the Company's common stock as of the grant date applied to the total number of shares granted and is amortized over the vesting period. There were 3,620 shares of restricted stock vested as of December 31, 2015 . There was $1.8 million and $0.3 million unearned share-based compensation associated with these awards as of December 31, 2015 and 2014 , respectively. The following table represents unvested restricted stock activity for the year ended December 31, 2015 : Number of Shares Weighted-Average Grant Date Fair Value Balance, beginning of year 12,892 $ 34.32 Granted 61,450 33.35 Canceled (667 ) 34.26 Forfeited (1,509 ) 32.99 Balance, end of year 72,166 $ 33.52 There was $0.5 million and $0.1 million in compensation expense that was included in salaries and benefits expense in the accompanying consolidated statements of income for the years ended December 31, 2015 and 2014 , respectively. There was no compensation expense included in salaries and benefits in the accompanying consolidated statements of income for the year ended December 31, 2013 . Stock Options The Company issues stock options to directors, officers, and other key employees. The option exercise price cannot be less than the fair value of the underlying common stock as of the date of the option grant and the maximum option term cannot exceed 10 years. The stock options granted were issued with vesting periods ranging from 3 to 5 years. At December 31, 2015 , there were 981,505 shares available for future issuance of option or restricted stock awards under approved compensation plans. For the years ended December 31, 2015 and 2014 , total stock option compensation expense that was included in salaries and employee benefits expense was $0.6 million and $0.7 million was included for the year ended December 31, 2013, respectively. The related income tax benefit in the accompanying consolidated statements of income was $0.2 million , $0.1 million , and $0.2 million for the years ended December 31, 2015 , 2014, and 2013, respectively. The Company uses the Black-Scholes option pricing model to estimate the fair value of the stock options awards. The following weighted-average assumptions were used for option awards granted during the years ended December 31 of the periods indicated: 2015 2014 2013 Expected dividend yield — % — % — % Weighted-average expected volatility 42.89 % 44.53 % 36.68 % Weighted-average risk-free interest rate 1.73 % 2.21 % 1.73 % Expected option term (in years) 6.0 6.0 6.0 Contractual term (in years) 10.0 10.0 10.0 Weighted-average grant date fair value $ 14.06 $ 15.56 $ 5.22 The assumptions above were based on multiple factors, primarily the historical stock option patterns of a group of publicly traded peer banks based in the southeastern United States. At December 31, 2015 , there was $1.0 million in unrecognized compensation cost related to stock options which is expected to be recognized over a weighted-average period of 1.3 years. The following table represents the activity related to stock options during the periods indicated: Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (Years) Options outstanding, December 31, 2012 809,017 $ 11.81 Granted 139,650 16.16 Exercised (76,966 ) 10.39 Forfeited or expired (16,600 ) 15.16 Options outstanding, December 31, 2013 855,101 13.48 Granted 38,013 34.32 Exercised (57,370 ) 12.26 Forfeited or expired (1,074 ) 22.13 Options outstanding, December 31, 2014 834,670 14.50 Granted 33,187 32.55 Exercised (42,409 ) 13.84 Forfeited or expired (4,252 ) 24.20 Options outstanding, December 31, 2015 821,196 $ 15.22 5.55 Options exercisable, December 31, 2013 374,535 $ 11.94 Options exercisable, December 31, 2014 522,600 $ 12.70 Options exercisable, December 31, 2015 621,255 $ 13.56 5.00 The following table presents weighted-average remaining life as of December 31, 2015 for options outstanding within the stated exercise prices: Options Outstanding Options Exercisable Exercise Price Range Per Share Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Life (Years) Number of Shares Weighted- Average Exercise Price $10.00-$12.70 306,494 $ 11.32 3.38 306,494 $ 11.32 $14.20-$15.88 441,322 15.00 6.54 299,405 14.92 $23.68-$34.35 73,380 32.81 8.64 15,356 32.01 Total Options 821,196 $ 15.22 5.55 621,255 $ 13.56 At December 31, 2015 , the aggregate intrinsic value of shares underlying outstanding stock options and underlying exercisable stock options was $18.2 million and $14.8 million , respectively.

Investments, All Other Investments [Abstract]
Financial Instruments With Off-Balance-Sheet Risk	Financial Instruments With Off-Balance-Sheet Risk The Company is a party to various financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit, which are recorded when they are funded. Such commitments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the accompanying consolidated financial statements. At December 31, 2015 and 2014 , the Company had made various commitments to extend credit of $822.0 million and $620.3 million , respectively. The Company’s management does not anticipate any material loss as a result of these transactions. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts disclosed above do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if considered necessary upon extension of credit, is based on management’s credit evaluation of the counterparty. Standby letters of credit represent commitments by the Company to meet the obligations of certain customers, if called upon. These financial instruments are considered guarantees in accordance with ASC 460. Outstanding standby letters of credit as of December 31, 2015 were $106.2 million and expire between 2016 and 2040 . Outstanding standby letters of credit as of December 31, 2014 , were $110.6 million and expire between 2015 and 2040 . Net unamortized fees related to letters of credit origination were $0.3 million as of December 31, 2015 and 2014. Net unamortized costs related to letters of credit origination were $0.4 million and $0.2 million as of December 31, 2015 and 2014 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation Matters On May 5, 2016, a purported securities class action suit was commenced in the United States District Court for the Eastern District of Louisiana, naming as defendants the Company, its Chairman and Chief Executive Officer, and its Chief Financial Officer. The lawsuit alleges violations of the Securities Exchange Act of 1934 and Rule 10b-5 in connection with allegedly false and misleading statements made by the Company related to its tax credit accounting practices and exposure to the oil and gas industry. The plaintiff seeks, among other things, damages for purchasers of the Company's common stock between May 10, 2013 and April 8, 2016. A group of institutional investors and a pension fund have each moved for appointment as lead plaintiff of the putative class. Briefing on the lead plaintiff motions was completed on July 19, 2016, and the parties currently await a decision on these motions from the Court. The Company believes that it has meritorious defenses and intend to defend this lawsuit vigorously. This lawsuit and any other related lawsuits are subject to inherent uncertainties, and the ultimate outcome of such litigation is necessarily unknown. The Company is unable to make a reasonable estimate of the amount or range of loss that could result from an unfavorable outcome in such matters. The SEC has commenced an investigation relating to the Company’s financial reporting. The Company is fully cooperating with the SEC. The Company cannot predict the duration or outcome of this investigation. Any action by the SEC or other government agency could result in civil or criminal sanctions against the Company and/or certain of its current or former officers, directors or employees. The Company is party to various other litigation matters incidental to the conduct of our business. Based upon its evaluation of information currently available, the Company believes that the ultimate resolution of any such proceedings will not have a material adverse effect, either individually or in the aggregate, on its financial condition, results of operations or cash flows. Leases The Company leases certain branch offices through noncancelable operating leases with terms that range from one to 30 years , with renewal options thereafter. Certain leases have escalation clauses and renewal options ranging from one to 59 years . Rent expense was approximately $3.6 million , $3.2 million , and $3.3 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. At December 31, 2015 , the minimum annual rental payments to be made under the noncancelable leases are as follows: (In thousands) Year ending December 31: 2016 $ 3,943 2017 3,935 2018 3,614 2019 3,441 2020 3,303 Thereafter 34,322 $ 52,558 At December 31, 2015, the Company has one capital lease related to a branch office in Crestview, Florida, which included renewal options for 20 years. The $1.2 million of assets, net of accumulated depreciation of $0.1 million , recorded under the capital lease is included within Bank premises and equipment, net in the accompanying consolidated balance sheets. The Company recorded amortization of $0.1 million related to the capital lease for the year ended December 31, 2015 , which has been included within depreciation expense. There were no costs related to capital leases included within depreciation for the years ended December 31, 2014 and 2013. At December 31, 2015 , the minimum annual rental payments, net of imputed interest, to be made under the capital lease are as follows: (In thousands) Year ending December 31: 2016 $ 46 2017 48 2018 50 2019 51 2020 53 Thereafter 965 $ 1,213 Off-Balance-Sheet Arrangements The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These transactions include commitments to extend credit in the ordinary course of business to approved customers. Generally, loan commitments have been granted on a temporary basis for working capital or commercial real estate financing requirements or may be reflective of loans in various stages of funding. These commitments are recorded on the Company’s financial statements as they are funded. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Loan commitments include unused commitments for open-end lines secured by one to four family residential properties and commercial properties, commitments to fund loans secured by commercial real estate, construction loans, business lines of credit, and other unused commitments. Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the customer. The Company minimizes its exposure to loss under loan commitments and standby letters of credit by subjecting them to credit approval and monitoring procedures. The effect on the Company’s revenues, expenses, cash flows, and liquidity of the unused portions of these commitments cannot be reasonably predicted because there is no guarantee that the lines of credit will be used. The liability for losses on unfunded commitments totaled $0.3 million and $0.2 million at December 31, 2015 and 2014 , respectively. The following is a summary of the total notional amount of loan commitments and standby letters of credit outstanding at December 31, 2015 and 2014 : (In thousands) 2015 2014 Standby letters of credit $ 106,232 $ 110,636 Unused loan commitments 715,759 509,665 Total $ 821,991 $ 620,301

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures, clarifies the principle that fair value should be based on the assumptions that market participants would use when pricing the asset or liability and establishes a fair value hierarchy that prioritizes the inputs used to develop those assumptions and measure fair value. The hierarchy requires companies to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 – Quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs. A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using pricing models or quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Examples include certain available for sale securities. The Company’s investment portfolio did not include Level 3 securities as of December 31, 2015 and December 31, 2014 . The Company has segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy, based on the inputs used to determine the fair value at the measurement date in the tables below: December 31, 2015 Fair Value Measurement Using (In thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Available for sale securities: U.S. government agency securities $ 149,675 $ — $ 149,675 $ — U.S. Treasury securities 12,703 — 12,703 — Municipal securities 12,100 — 12,100 — Mortgage-backed securities 77,511 — 77,511 — Corporate bonds 7,823 — 7,823 — Other equity securities 20 20 — — Other debt securities 25,994 — 25,994 — Total $ 285,826 $ 20 $ 285,806 $ — Liabilities Derivative instruments $ 19,700 $ — $ 19,700 $ — December 31, 2014 Fair Value Measurement Using (In thousands) Total Quoted Prices Significant Significant Assets Available for sale securities: U.S. government agency securities $ 157,527 $ — $ 157,527 $ — U.S. Treasury securities 12,610 — 12,610 — Municipal securities 12,246 — 12,246 — Mortgage-backed securities 57,087 — 57,087 — Corporate bonds 8,177 — 8,177 — $ 247,647 $ — $ 247,647 $ — Derivative instruments 37 — 37 — Total $ 247,684 $ — $ 247,684 $ — Liabilities Derivative instruments $ 12,953 $ — $ 12,953 $ — The Company has segregated all financial assets and liabilities that are measured at fair value on a nonrecurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the tables below: December 31, 2015 Fair Value Measurement Using (In thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Loans $ 80,006 $ — $ — $ 80,006 OREO 3,701 — — 3,701 Investment in tax credit entities 1,425 — — 1,425 $ 85,132 $ — $ — $ 85,132 December 31, 2014 Fair Value Measurement Using (In thousands) Total Quoted Prices Significant Significant (Restated) (Restated) Assets Loans $ 20,679 $ — $ — $ 20,679 OREO 3,022 — — 3,022 Investment in tax credit entities 1,672 — — 1,672 $ 25,373 $ — $ — $ 25,373 In accordance with ASC Topic 310, the Company records loans and other real estate considered impaired at the lower of cost or fair value. Impaired loans, recorded at fair value, are Level 3 assets measured using appraisals from external parties of the collateral, less any prior liens primarily using the market or income approach. The residual value or fair value of the Company's investment in tax credit entities are Level 3 assets measured using appraisals or actual costs incurred on the underlying individual properties, applying an estimated inflation rate on the appraised values or actual costs and discounting the cash flows. The Company did not record any liabilities at fair value for which measurement of the fair value was made on a nonrecurring basis during the years ended December 31, 2015 and December 31, 2014 . ASC 820 requires the disclosure of the fair value for each class of financial instruments for which it is practicable to estimate. The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. ASC 820 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value. Cash and Cash Equivalents The carrying amounts of these short-term instruments approximate their fair values and would be classified within Level 1 of the hierarchy. Investment in Short-Term Receivables The carrying amounts of these short-term receivables approximate their fair value and would be classified within Level 1 of the hierarchy. Investment Securities Securities are classified within Level 1 where quoted market prices are available in the active market. If quoted market prices are unavailable, fair value is estimated using pricing models or quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Inputs include securities that have quoted prices in active markets for identical assets. Loans For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values are based on carrying values. Fair values for fixed-rate commercial real estate, commercial loans, and consumer loans are estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms and borrowers of similar credit quality. Fair value of mortgage loans held for sale is based on commitments on hand from investors or prevailing market rates. The fair value associated with the loans includes estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows, which would be classified as Level 3 of the hierarchy. Deposits The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts) and would be categorized within Level 2 of the fair value hierarchy. The carrying amounts of variable-rate, fixed-term money market accounts approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. The fair value of the Company’s interest-bearing deposits would, therefore, be categorized within Level 3 of the fair value hierarchy. Short-Term Borrowings and Repurchase Agreements The carrying amounts of these short-term instruments approximate their fair values and would be classified within Level 2 of the hierarchy. Long-Term Borrowings The fair values of long-term borrowings are estimated using discounted cash flows analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The fair value of the Company’s long-term debt would, therefore, be categorized within Level 3 of the fair value hierarchy.

Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are susceptible to a significant change in the near term are the allowance for loan losses, income tax provision, fair value adjustments, impairment on tax credit investments, and share-based compensation.
Concentration of Credit Risk	Concentration of Credit Risk The Company’s loan portfolio consists of the various types of loans described in Note 8. Real estate or other assets secure most loans. The majority of these loans have been made to individuals and businesses in the Company’s market area of southeastern Louisiana and the Florida panhandle, which are dependent on the area economy for their livelihoods and servicing of their loan obligations. The Company does not have any significant concentrations to any one industry or customer. The Company maintains deposits in other financial institutions that may, from time to time, exceed the federally insured deposit limits.
Acquisition Accounting	Business Combinations Assets and liabilities acquired in business combinations are recorded at their acquisition date fair values. In accordance with ASC Topic 805, Business Combinations, the Company generally records provisional amounts at the time of acquisition based on the information available to the Company. The provisional estimates of fair values may be adjusted for a period of up to one year (“measurement period”) from the date of acquisition if new information obtained about facts and circumstances that existed as of the acquisition date, if known, would have affected the measurement of the amounts recognized as of that date. Loans generally represent a significant portion of the assets acquired in the Company’s business acquisitions. If the Company discovers that it has materially underestimated the credit losses expected in the loan portfolio based on information available at the acquisition date within the measurement period, it will reduce or eliminate the gain and/or increase goodwill recorded on the acquisition in the period the adjustment is recorded. If the Company determines that losses arose subsequent to acquisition date, such losses are reflected as a provision for credit losses.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include the amount in the accompanying consolidated balance sheet caption, cash and cash equivalents, which represents cash on hand, balances due from other financial institutions, and federal funds sold with original maturities less than three months.
Investment Securities	Investment Securities Investment securities are classified either as held to maturity or available for sale. Management determines the classification of securities when they are purchased. Investment securities that the Company has the ability and positive intent to hold to maturity are classified as securities held to maturity and are stated at amortized cost. The amortized cost of debt securities classified as held to maturity or available for sale is adjusted for amortization of premiums and accretion of discounts over the contractual life of the security using the effective interest method or, in the case of mortgage-backed securities, over the estimated life of the security using the effective yield method. Such amortization or accretion is included in interest income on securities. Securities that may be sold in response to changes in interest rates, liquidity needs, or asset liability management strategies are classified as securities available for sale. These securities are carried at fair value, with net unrealized gains or losses excluded from earnings and shown as a separate component of shareholders’ equity in accumulated other comprehensive income (loss), net of income taxes. Any expected credit loss due to the inability to collect all amounts due accordingly to the security’s contractual terms is recognized as a charge against earnings. Any remaining unrealized loss related to other factors is recognized in other comprehensive income (loss), net of taxes. Realized gains and losses on both held to maturity securities and available for sale securities are computed based on the specific-identification method. Realized gains and losses and declines in value judged to be other than temporary are included in net investment securities gains and losses. Unrealized losses on securities are evaluated to determine if the losses are temporary, based on various factors, including the cause of the loss, prospects for recovery, projected cash flows, collateral values, credit enhancements and other relevant factors, and management’s intent and ability not to sell the security until the fair value exceeds amortized cost. A charge is recognized against earnings for all or a portion of the impairment if the loss is determined to be other than temporary.
Investment in Short-Term Receivables	Investment in Short-Term Receivables The Company invests in short-term receivables which are purchased on an exchange. These short-term receivables have repayment terms of less than a year. The investments are recorded at cost plus accreted discount. The Company evaluates its investments in short-term receivables for impairment once they become delinquent.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value, in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Loans held for sale have primarily been fixed-rate, single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within 120 days. These loans are sold with the mortgage servicing rights released. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances which may include early payment default, breach of representations or warranties, and documentation deficiencies.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered or in the case of a loan participation, a portion of the asset has been surrendered and meets the definition of a "participating interest". Control over transferred assets is deemed to be surrendered when 1) the assets have been isolated from the Company, 2) the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets, and 3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Should the transfer not meet these three criteria, the transaction is treated as a secured financing.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the principal amount outstanding, net of unamortized fees and costs on originated loans and allowances for loan losses. Loan origination fees and certain direct loan origination costs are deferred and amortized over the lives of the respective loans as a yield adjustment using the effective interest method. Interest income on loans is accrued as earned using the interest method over the life of the loan. Interest on loans deemed uncollectible is excluded from income. The accrual of interest is discontinued and reversed against current income once loans become more than 90 days past due or earlier if conditions warrant. The past due status of loans is determined based on the contractual terms. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status, interest accrued and unpaid during prior periods is reversed. Generally, any payments on nonaccrual loans are applied first to outstanding loan principal amounts and then to the recovery of the charged-off loan amounts. Any excess is treated as recovery of lost interest and fees. Loans are returned to accrual status after a minimum of six consecutive monthly payments have been made in a timely manner. The Company considers a loan to be impaired when, based upon current information and events, it believes it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. The Company’s impaired loans include troubled debt restructurings (TDRs) and performing and nonperforming loans for which full payment of principal or interest is not expected. The Company calculates a reserve required for impaired loans based on the present value of expected future cash flows discounted using the loan’s effective interest rate or the fair value of the collateral securing the loan. Third-party property valuations are obtained at the time of origination for real estate-secured loans. The Company obtains updated appraisals on all impaired loans at least annually. In addition, if an intervening event occurs that, in management’s opinion, would suggest further deterioration in value, the Company obtains an updated appraisal. These policies do not vary based on loan type. Any exposure arising from the deterioration in value of collateral evidenced by the appraisal is recorded as an adjustment to the loan loss reserve in the case of an impaired loan or as an adjustment to income in the case of foreclosed property.
Troubled Debt Restructurings	Troubled Debt Restructurings The Company periodically grants concessions to its customers in an attempt to protect as much of its investment as possible and minimize the risk of loss. These concessions may include restructuring the terms of a customer loan, thereby adjusting the customer’s payment requirements. In order to be considered a TDR, the Company must conclude that the restructuring constitutes a concession and the customer is experiencing financial difficulties. The Company defines a concession to a customer as a modification of existing loan terms for economic or legal reasons that it would otherwise not consider. Concessions are typically granted through an agreement with the customer or are imposed by a court of law. Concessions include modifying original loan terms to reduce or defer cash payments required as part of the loan agreement, including but not limited to: • A reduction of the stated interest rate for the remaining original life of the debt; • Extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk characteristics; • Reduction of the face amount or maturity amount of the debt as stated in the agreement; or • Reduction of accrued interest receivable on the debt. In its determination of whether the customer is experiencing financial difficulties, the Company considers numerous indicators, including but not limited to: • Whether the customer is currently in default on its existing loan or is in an economic position where it is probable the customer will be in default on its loan in the foreseeable future without a modification; • Whether the customer has declared or is in the process of declaring bankruptcy; • Whether there is substantial doubt about the customer’s ability to continue as a going concern; • Whether, based on its projections of the customer’s current capabilities, the Company believes the customer’s future cash flows will be insufficient to service the debt, including interest, in accordance with the contractual terms of the existing agreement for the foreseeable future; or • Whether, without modification, the customer cannot obtain sufficient funds from other sources at an effective interest rate equal to the current market rate for similar debt for a nontroubled debtor. If the Company concludes that both a concession has been granted and the concession was granted to a customer experiencing financial difficulties, the Company identifies the loan as a TDR. For purposes of the determination of an allowance for loan losses on these TDRs, the loan is reviewed for specific impairment in accordance with the Company’s allowance for loan loss methodology. If it is determined that losses are probable on such TDRs, either because of delinquency or other credit quality indicators, the Company establishes specific reserves for these loans.
Acquisition Accounting for Loans	Acquisition Accounting for Loans The Company accounts for business combinations in accordance with Financial Accounting Standards Board (FASB) ASC 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. The fair value of loans that do not have deteriorated credit quality are accounted for in accordance with ASC 310-20, Nonrefundable Fees and Other Costs, and is represented by the expected cash flows from the portfolio discounted at current market rates. In estimating the cash flows, the Company makes assumptions about the amount and timing of principal and interest payments, estimated prepayments, estimated default rates, estimated loss severities in the event of defaults, and current market rates. The fair value adjustment is amortized over the life of the loan using the effective interest method. The Company accounts for certain acquired loans with deteriorated credit quality under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. In accordance with ASC 310-30 and in estimating the fair value of loans with deteriorated credit quality as of the acquisition date, the Company: (a) calculates the contractual amount and timing of undiscounted principal and interest payments (the undiscounted contractual cash flows), and (b) estimates the amount and timing of undiscounted expected principal and interest payments (the undiscounted expected cash flows). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the loans with deteriorated credit quality is the accretable yield. The accretable yield is recorded into interest income over the estimated lives of the loans using the effective yield method. The accretable yield changes over time as actual and expected cash flows vary from the estimated cash flows at acquisition. Decreases in expected cash flows subsequent to acquisition result in recognition of a provision for loan loss. The accretable yield is measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The remaining undiscounted expected cash flows are calculated at each financial reporting date, based on information currently available. Increases in expected cash flows over those originally estimated increase the accretable yield and are recognized prospectively as interest income. Increases in expected cash flows may also lead to the reduction of any allowance for loan losses recorded after the acquisition. Decreases in expected cash flows compared to those originally estimated decrease the accretable yield and are recognized by recording an allowance for loan losses. As the accretable yield increases or decreases from changes in cash flow expectations, the offset is an increase or decrease to the nonaccretable difference. There is no carryover of allowance for loan losses, as the loans acquired are initially recorded at fair value as of the date of acquisition.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents an estimate that management believes will be adequate to absorb probable incurred losses on existing loans in its portfolio at the balance sheet date. The allowance is based on an evaluation of the collectability of loans and prior loss experience of the Company. While management uses available information to make loan loss allowance evaluations, adjustments to the allowance may be necessary based on changes in economic and other conditions or changes in accounting guidance. See Note 8 for an analysis of the Company’s allowance for loan losses by portfolio and portfolio segment, and credit quality information by class. Management has an established methodology to determine the allowance for loan losses that assesses the risks and losses inherent in its portfolio and portfolio segments. The Company utilizes an internally developed model that requires significant judgment to determine the estimation method that fits the credit risk characteristics of the loans in its portfolio and portfolio segments. The allowance for loan losses is established through a provision for loan losses charged to expense. A similar methodology and model is utilized by the Company to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in other liabilities. The appropriateness of the allowance for loan losses is determined in accordance with generally accepted accounting principles. The Company’s loan portfolio is disaggregated into portfolio segments for purposes of determining the allowance for loan losses. The Company’s portfolio segments include commercial real estate, consumer real estate, commercial and industrial, and consumer loans. The Company further disaggregates the commercial and consumer real estate portfolio segments into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within each commercial real estate portfolio segment include commercial real estate construction and commercial real estate mortgage. Classes within each consumer real estate portfolio segment include consumer real estate construction and consumer real estate mortgage. Loans are charged off against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The allowance for loan losses consists of specific and general reserves. The Company determines specific reserves based on the provisions of ASC 310, Receivables. The Company’s allowance for loan losses includes a measure of impairment for those loans specifically identified for evaluation under the topic. This measurement is based on a comparison of the recorded investment in the loan with either the expected cash flows discounted using the loan’s original contractual effective interest rate or the fair value of the collateral underlying certain collateral-dependent loans. Collectability of principal and interest is evaluated in assessing the need for a loss accrual. Loans identified as impaired are individually evaluated periodically for impairment. General reserves are based on management’s evaluation of many factors and reflect an estimated measurement of losses related to loans not individually evaluated for impairment. These loans are grouped into portfolio segments. The loss rates are derived from historical loss factors of the Company sustained on loans according to their risk grade, as well as qualitative and economic factors, and may be adjusted for Company-specific factors. Loss rates are reviewed quarterly and adjusted as management deems necessary based on changing borrower and/or collateral conditions and actual collections and charge-off experience. The loss emergence period is evaluated and derived from historical data based on the date of the loss event to the actual date of charge-off and the resulting loss emergence period is applied as a factor against the historical loss factor which is reviewed annually. Based on observations made through a qualitative review, management may apply qualitative adjustments to the quantitatively determined loss estimates at a group and/or portfolio segment level as deemed appropriate. Primary qualitative and environmental factors that may not be directly reflected in quantitative estimates include: • Asset quality trends; • Changes in lending policies; • Trends in the nature and volume of the loan portfolio, including the existence and effect of any portfolio concentrations; • Changes in experience and depth of lending staff; and • National and regional economic trends. Changes in these factors are considered in determining the directional consistency of changes in the allowance for loan losses. The impact of these factors on the Company’s qualitative assessment of the allowance for loan losses can change from period to period based on management’s assessment to the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for loan losses.
Credit-Related Financial Instruments	Credit-Related Financial Instruments The Company accounts for its guarantees in accordance with the provisions of ASC 460, Guarantees. In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card agreements, and standby letters of credit. Such financial instruments are recorded when they are funded.
Premises and Equipment	Premises and Equipment Land is carried at cost. Buildings, furniture, fixtures, and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated life of each respective type of asset as follows: Buildings 40 years Furniture, fixtures, and equipment 5 - 15 years Leasehold improvements are amortized using the straight-line method over the periods of the leases, including options expected to be exercised, or the estimated useful lives, whichever is shorter. Gains and losses on disposition and maintenance and repairs are included in current operations. Rental expense on leased property is recognized on a straight-line basis over the original lease term plus options that management expects to exercise. Fixed rental increases that are determinable are expensed over the lease period, including any option periods which are expected to be exercised, using a straight-line lease expense method.
Other Real Estate	Other Real Estate Assets acquired through, or in lieu of, loan foreclosure are held for sale and are recorded at a new cost basis determined at the date of foreclosure as the lower of cost or fair value less estimated cost to sell. Cost is defined as the recorded investment in the loan. Subsequent to foreclosure, valuation allowances are established for any decreases in the estimate of the asset’s fair value or selling costs. Revenues and expenses from operations and changes in the valuation allowance are included in current earnings.
Goodwill	Goodwill Goodwill represents the excess of the consideration paid in a business combination over the fair value of the identifiable net assets acquired. Goodwill is not amortized, but is assessed for potential impairment at a reporting unit level on an annual basis, on October 1, or whenever events or changes in circumstances indicate that it is more likely than not the fair value of a reporting unit is less than its respective carrying amount. As part of its testing, the Company may elect to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the results of the qualitative assessment indicate that more likely than not a reporting unit’s fair value is less than its carrying amount, the Company determines the fair value of the respective reporting unit (through the application of various quantitative valuation methodologies) relative to its carrying amount to determine whether quantitative indicators of potential impairment are present (i.e., Step 1). The Company may also elect to bypass the qualitative assessment and begin with Step 1. If the results of Step 1 indicate that the fair value of the reporting unit may be below its carrying amount, the Company determines the fair value of the reporting unit’s assets and liabilities, considering deferred taxes, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill (i.e., Step 2).
Intangible assets subject to amortization	Intangible assets subject to amortization The Company’s acquired intangible assets that are subject to amortization include core deposit intangibles and are amortized on a straight-line basis over their estimated useful lives and evaluated annually for impairment.
Investments in Real Estate Properties	Investments in Real Estate Properties FNBC CDC invests in real estate properties, which are carried at cost. Costs of construction are capitalized during the construction period and do not include interest. The Company periodically obtains as-is appraisals to determine the recoverability of its investments for which it intends to sell. For properties the Company intends to hold, the Company assesses recoverability based on the cash flows of the underlying properties.
Investments in Tax Credit Entities, net	Investments in Tax Credit Entities, net As part of its Community Reinvestment Act responsibilities and due to their favorable economics, the Company invests in tax credit-motivated projects. These projects produce tax credits issued under Federal Low-Income Housing, Federal Historic Rehabilitation, and Federal New Markets Tax Credits (Federal NMTC) programs. The Company generates its returns on tax credit motivated projects through the receipt of federal, and if applicable, state tax credits as well as equity returns. The federal tax credits are recorded as an offset to the income tax provision in the year that they are earned under federal income tax law – over 10 to 15 years, beginning in the year in which rental activity commences for Federal Low-Income Housing credits, in the year of the issuance of the certificate of occupancy and the property being placed into service for Federal Historic Rehabilitation credits, and over 7 years for Federal NMTC upon the investment of funds into the CDE. These credits, if not used in the tax return for the year of origination, can be carried forward for 20 years. The state credits are recorded in income when earned (usually when the project is placed in service) and sold to investors since the Company pays minimal state income taxes under Louisiana tax law. The Company invests in projects generating Federal Low-Income Housing credits, by investing in a tax credit entity, usually a limited liability company, which owns the real estate. The Company receives a 99.99% nonvoting interest in the entity that must be retained during the compliance period for the credits ( 15 years). Control of the tax credit entity rests in the .01% interest general partner, who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. The Company accounts for its investment in Federal Low-Income Housing credits utilizing the equity method of accounting. The Company begins to evaluate its investment for impairment at the time the tax credits are earned through the end of the 15 year compliance period. The Company evaluates its investment at the end of each reporting period for impairment and any residual returns are expected to be minor. For Federal Historic Rehabilitation credits, the Company invests in a tax credit entity, usually a limited liability company, which owns the real estate or a master tenant structure. In some cases, the Company receives a 99% nonvoting interest in the tax credit entity that must be retained during the compliance period for the credits ( 5 years). In some instances, the Company invests 99% in a pass through entity called a master tenant, which maintains an ownership interest in a limited liability company which owns the real estate. In most cases, the Company’s interest in the entity (in either structure) is generally reduced from a 99% interest to a 0% to 25% interest at the end of the compliance period. Control of the tax credit entity rests in the 1% interest general partner (in either structure), who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. The Company accounts for its investment in Federal Historic Rehabilitation credits utilizing the equity method of accounting. The Company begins to evaluate its investment for impairment at the time the credit is earned, which is typically in the year the project is placed in service, through the end of its compliance period. The Company evaluates its investment at the end of each reporting period for impairment and any expected residual returns reduce the amount of impairment recognized. For Federal NMTC, a different structure is required by federal tax law. In order to distribute Federal NMTC, the federal government allocates such credits to CDEs. The Company invests in both CDEs formed by unaffiliated parties and in CDEs formed by the Company. Projects must be commercial or real estate operations and are qualified by their location in low- income areas or by their employment of, or service to, low-income citizens. A CDE, in most cases, creates a special-purpose subsidiary for each project through which the credits are allocated and through which the proceeds from the tax credit investor and a leverage lender, if applicable, flow through to the project, which in turn generate the credit. The credits are calculated at 39% of the total CDE allocation to the project at the rate of 5% for the first three years and 6% for the next four years. Federal tax law requires special terms benefiting the qualified project, which can include below-market interest rates. The Company evaluates its investment for impairment under the equity method of accounting at the end of each reporting period, beginning at the time the tax credits are earned on the project through the end of the seven-year compliance period, and any residual returns are expected to be minor. When the Company also has a loan to the project, it is reported as a loan in the consolidated balance sheet, as the Company has credit exposure to the project and the loan is repaid at the end of the compliance period. In general, the debt has no principal payments during the compliance period but the Company may require the project to fund a sinking fund over the compliance period to achieve the same risk reduction effect as if principal is being amortized. When the Company is the tax credit investor in a CDE formed by an unaffiliated party, it has no control of the applicable CDE or the CDE’s special-purpose subsidiary. For projects which are funded through FNBC CDE, the Company consolidates its CDE and the specifically formed special-purpose entities since it maintains control over these entities; however, the Company does not have control over the entity which oversees the project. As part of the activities of FNBC CDE, the Company makes investments in the CDE for purposes of providing equity to the projects sponsored by the FNBC CDE. When a project is funded through FNBC CDE, the CDE will receive a CDE management fee at the time of the project's closing of approximately 4% and an annual fee of 0.5% of the qualified equity investment in the project. The annual fee is received until the end of the Federal NMTC compliance period. The CDE management fee earned is recorded in the consolidated statement of income as a component of noninterest income. The Company may pay a fee to the CDE when the project is funded through a CDE other than FNBC CDE at the time of a project's closing and annually during the compliance period for the allocation of the credits. The fee is recorded as a component of noninterest expense in the Company's consolidated statement of income over the Federal NMTC compliance period. The Company has the risk of credit recapture if the project fails during the compliance period for Federal Low-Income Housing and Federal Historic Rehabilitation transactions. For Federal NMTC transactions, the risk of credit recapture exists if investment requirements are not maintained during the compliance period. The risk of recapture for Federal NMTC transactions when the project is funded by FNBC CDE is described in Note 14. Such events, although rare, are accounted for when they occur and no such events have occurred to date involving FNBC CDE.
Variable Interest Entities	Variable Interest Entities VIEs are entities that, in general, either do not have equity investors with voting rights or that have equity investors that do not provide sufficient financial resources for the entity to support its activities. The Company uses VIEs in various legal forms to conduct normal business activities. The Company reviews the structure and activities of VIEs for possible consolidation. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits of the VIE that could potentially be significant to the VIE. A VIE often holds financial assets, including loans or receivables, real estate, or other property. The company with a controlling financial interest, known as the primary beneficiary, is required to consolidate the VIE. Noncontrolling variable interests in certain limited partnerships for which the Company does not absorb a majority of expected losses or receive a majority of expected residual returns are not included in the accompanying consolidated financial statements. Refer to Notes 14 and 15 for further detail.
Stock-Based Compensation Plans	Stock-Based Compensation Plans The Company has stock-based employee compensation plans, which provide for the issuance of stock options and restricted stock. The Company accounts for stock-based employee compensation in accordance with the fair value recognition provisions of ASC 718, Compensation—Stock Compensation. Compensation cost is recognized as expense over the service period, which is generally the vesting period of the options and restricted stock. The expense is reduced for estimated forfeitures over the vesting period and adjusted for actual forfeitures as they occur. As a result, compensation cost for all share-based payments is reflected in net income as part of salaries and employee benefits in the accompanying consolidated statements of income. See Note 26 for additional information on the Company’s stock-based compensation plans.
Income Taxes	Income Taxes The Company accounts for income taxes under the liability method. Deferred tax assets and liabilities are established for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities using enacted tax rates expected to be in effect during the year in which the basis differences reverse. Valuation allowances are established against deferred tax assets if, based on all available evidence, it is more likely than not some or all of the assets will not be realized. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Company to report information regarding its exposure to various tax positions taken by the Company. The Company has determined whether any tax positions have met the recognition threshold and has measured the Company’s exposure to those tax positions. Management believes that the Company has adequately addressed all relevant tax positions and that there are no unrecorded tax liabilities. Any interest or penalties assessed to the Company are recorded in operating expenses. No interest or penalties from any taxing authorities were recorded in the accompanying consolidated financial statements. Federal, state, and local taxing authorities generally have the right to examine and audit the previous three years of tax returns filed. The Company is also required to reduce its tax basis of the investment in certain of the projects that generated the Federal NMTC or Federal Historic Rehabilitation tax credits by the amount of the credit generated in that year based on the taxable entity structure of the investee.
Earnings Per Share	Earnings Per Share Basic earnings per common share is computed based upon net income attributable to common shareholders divided by the weighted-average number of common shares outstanding during each period. Diluted earnings per common share is computed based upon net income, adjusted for dilutive participating securities, divided by the weighted-average number of common shares outstanding during each period and adjusted for the effect of dilutive potential common shares calculated using the treasury stock method and the assumed conversion for any dilutive convertible securities. In determining net income attributable to common shareholders, the net income attributable to participating securities is excluded. The Company issued Series C preferred stock in 2011, which is considered a participating security because it shares in any dividends paid to common shareholders. The assumed conversion of the Series C preferred stock is excluded from the calculation of diluted earnings per share due to the fact that the shares are contingently issuable and the contingency still existed at the end of 2014.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and cash flow hedges, are reported as a separate component of the equity section of the balance sheet; such items, along with net income, are components of comprehensive income (loss).
Derivative Financial Instruments	Derivative Financial Instruments ASC 815, Derivatives and Hedging, requires that all derivatives be recognized as assets or liabilities in the balance sheet at fair value. The Company may enter into derivative contracts to manage exposure to interest rate risk or meet the financing and/or investing needs of its customers. In the course of its business operations, the Company is exposed to certain risks, including interest rate, liquidity, and credit risk. The Company, as part of its management of interest rate risk, utilizes derivative financial instruments, primarily through management of exposure through the receipt or payment of future cash amounts based on interest rates. The Company’s derivative financial instruments manage the differences in the timing, amount, and duration of expected cash receipts and payments. Derivatives which are designated and qualify as a hedge of the exposure to variability in expected future cash flows or other types of forecasted transactions are considered cash flow hedges. The Company prepares written hedge documentation for all derivatives which are designated as cash flow hedges. The written hedge documentation includes identification of, among other items, the risk management objective, hedging instrument, hedged item and methodologies for assessing and measuring hedge effectiveness and ineffectiveness, along with support for management’s assertion that the hedge will be highly effective. These methods are consistent with the Company’s approach to managing risk. The Company reports these net in the accompanying consolidated balance sheets when the Company has a master netting arrangement. As of December 31, 2015 and December 31, 2014, there were net amounts reported. For designated hedging relationships, the Company performs retrospective and prospective effectiveness testing to determine whether the hedging relationship has been highly effective in offsetting changes in cash flows of hedged items and whether the relationship is expected to continue to be highly effective in the future. Assessments of hedge effectiveness and measurements of hedge ineffectiveness are performed at least quarterly. The effective portion of the changes in the fair value of a derivative that is highly effective and that has been designated and qualifies as a cash flow hedge are initially recorded in accumulated other comprehensive income (loss) and reclassified to earnings in the same period that the hedged item impacts earnings or when the hedging relationship is terminated; any ineffective portion is recorded in earnings immediately. Hedge accounting ceases on transactions that are no longer deemed effective, or for which the derivative has been terminated or de-designated. For discontinued cash flow hedges, the unrealized gains and losses recorded in accumulated other comprehensive income (loss) would be reclassified to earnings during the period or periods in which the previously designated hedged cash flows affect earnings (straight-line amortization/accretion) unless it was determined that the transaction was probable to not occur, whereby any unrealized gains and losses in accumulated other comprehensive income would be immediately reclassified to earnings. Note 20 describes the derivative instruments currently used by the Company and discloses how these derivatives impact the Company’s financial position and results of operations.
Fair Value	Fair Value U.S. GAAP requires the use of fair values in determining carrying values of certain assets and liabilities in the financial statements, as well as for specific disclosures about certain assets and liabilities. ASC 820, Fair Value Measurements and Disclosures , established a fair value hierarchy that prioritizes the inputs to these valuation techniques used to measure fair value giving preference to quoted prices in active markets (Level 1) and the lowest priority to unobservable inputs such as a reporting entity's own data or information or assumptions developed from this data (Level 3). Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in markets that are not active, observable inputs other than quoted prices, such as interest rates and yield curves, and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures, clarifies the principle that fair value should be based on the assumptions that market participants would use when pricing the asset or liability and establishes a fair value hierarchy that prioritizes the inputs used to develop those assumptions and measure fair value. The hierarchy requires companies to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 – Quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs. A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using pricing models or quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Examples include certain available for sale securities.
Segments	Segments All of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment. Because the overall banking operations comprise substantially all of the consolidated operations and none of the Company’s other subsidiaries, either individually or in the aggregate, meet quantitative materiality thresholds, no separate segment disclosures are presented in the accompanying consolidated financial statements.
Reclassifications	Reclassifications Some amounts previously reported have been adjusted to reflect certain reclassification adjustments to conform to the current period presentation. These include reclassifications of amounts previously reported in loans to investment in tax credit entities, net; amounts previously reported in premises and equipment to investment in real estate entities; and certain amounts previously reported in occupancy and equipment expenses to rental property expenses. The Company has presented rental property expenses, previously presented as a component of other noninterest expense in its consolidated statements of income, and rental property income, previously presented as a component of other noninterest income in its consolidated statements of income, as separate components on its consolidated statements of income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU No. 2014-01 In January 2014, the FASB issued ASU No. 2014-01, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, which permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). This ASU applies to all reporting entities that invest in qualified affordable housing projects through limited liability entities that are flow-through entities for tax purposes and became effective for fiscal years and interim periods beginning after December 15, 2014. After evaluating the provisions of this release the Company determined it would not adopt this ASU, resulting in no impact on the Company's financial condition or results of operations. ASU No. 2014-09 and 2015-14 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 205): An Amendment of the FASB Accounting Standards Codification , which clarifies the principles for recognizing revenue from contracts with customers. The new accounting guidance, which does not apply to financial instruments, clarifies that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As part of that principle, the entity should identify the contract(s) with the customer, identify the performance obligation(s) of the contract, determine the transaction price, allocate that transaction price to the performance obligation(s) of the contract, and then recognize revenue when or as the entity satisfies the performance obligation(s). In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date , which deferred the original effective date declared in ASU No. 2014-09 by one year. Accordingly, the amendments in ASU No. 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The amendments will be applied through the election of one of two retrospective methods. The Company is in the process of evaluating the new guidance and its impact on the Company's financial condition or results of operations. ASU No. 2014-12 In June 2014, the FASB issued ASU No. 2014-12 Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is intended to resolve the diverse accounting treatments of these types of awards in practice and is effective for annual and interim periods beginning after December 15, 2015. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2014-13 In August 2014, the FASB issued ASU No. 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and Financial Liabilities of a Consolidated Collateralized Financing Entity , which will allow an alternative fair value measurement approach for consolidated collateralized financing entities (CFEs) to eliminate a practice issue that results in measuring the fair value of a CFE’s financial assets at a different amount from the fair value of its financial liabilities even when the financial liabilities have recourse to only the financial assets. The approach would permit the parent company of a consolidated CFE to measure the CFE’s financial assets and financial liabilities based on the more observable of the fair value of the financial assets and the fair value of the financial liabilities. The new accounting guidance is for the annual period ending after December 15, 2015, and for annual periods and interim periods thereafter, with early application permitted as of the beginning of an annual period. The Company does not expect the new guidance to have a material impact on the Company’s financial condition or results of operations. ASU No. 2014-15 In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , which will require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards in connection with preparing financial statements for each annual and interim reporting period. The new accounting guidance is for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter, with early application permitted. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2015-02 In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which eliminates the deferral of FAS 167 and makes changes to both the variable interest model and the voting model. The new accounting guidance is for the annual period beginning after December 15, 2015, and for annual periods and interim periods thereafter, with early application permitted. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2015-03 In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The new accounting guidance is for the annual period beginning after December 15, 2015, and for annual periods and interim periods thereafter, with early application permitted. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2015-05 In April 2015, the FASB issued ASU No. 2015-05, Intangibles-Goodwill and Other Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement , which provides guidance to clarify a customer’s accounting for fees paid in a cloud computing arrangement. The new accounting guidance is for the annual period beginning after December 15, 2015, and for annual periods and interim periods thereafter, with early application permitted. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2015-16 In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments , which requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined as if the accounting had been completed at the acquisition date. The new accounting guidance is for the annual period beginning after December 15, 2015, and for annual periods and interim periods thereafter. The amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update with early application permitted for financial statements that have not been issued. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-01 In January 2016, the FASB issued ASU No. 2016-01, Financial Instrument-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , which (1) requires equity investments to be measured at fair value with changes in fair value recognized in net income, (2) simplifies the impairment assessment of equity investments with readily determinable fair values by requiring a qualitative assessment to identify impairment, (3) eliminates the requirement to disclose the fair value instruments measured at amortized cost for entities that are not public business entities, (4) eliminates the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (5) requires public business entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes, (6) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (7) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements, and (8) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity's other deferred tax assets. The new accounting guidance is for the annual period beginning after December 15, 2017, including interim periods. The Company does not expect the new guidance to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-02 In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term for all leases (with the exception of short-term leases) at the commencement date. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees will no longer be provided with a source of off-balance sheet financing. The guidance is for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early application is permitted for all entities upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently evaluating the provisions of the ASU to determine the potential impact the new standard will have on the Company's financial condition or results of operations. ASU No. 2016-05 In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, which clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not, in and of itself, require dedesignation of that hedging relationship. The amendments apply to all reporting entities for which there is a change in the counterparty to a derivative instrument that has been designated as a hedging instrument. The amendments are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The amendments may be applied on either a prospective basis or a modified retrospective basis. The adoption of this guidance is not expected to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-06 In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments, that requires embedded derivatives to be separated from the host contract and accounted for separately as derivatives if certain criteria are met. The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments clarify what steps are required when assessing whether the economic characteristics and risks or call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts, which is one of the criteria for bifurcating an embedded derivative. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event triggers the ability to exercise a call (put) option is related to interest rates or credit risks. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-07 In March 2016, the FASB issued ASU 2016-07, Investments- Equity Method and Joint Ventures (Topic 323), which simplifies the transition to the equity method of accounting. The amendments affect all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available for sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years beginning after December 15, 2016. The adoption of this guidance is not expected to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-08 In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), that improves the operability and understandibility of the implementation guidance on principal versus agent considerations. The amendments relate to when another party, along with the entity, is involved in providing a good or service to a customer. It requires an entity to determine whether the nature of its promise is to provide that good or service to the customer (i.e., the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (i.e., the entity is an agent). Public entities should apply the amendments for annual reporting periods beginning after December 15, 2017. The adoption of this guidance is not expected to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-09 In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, to improve the accounting for employee share-based payments. Several aspects of the accounting for share-based payment award transactions are simplified, including income tax consequences; classification of awards as either equity or liabilities; and classification on the statement of cash flows. The amendments are effective for public business entities for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any interim or annual period. The Company is currently assessing the pronouncement and the impact of adoption. ASU No. 2016-10 In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, that clarifies the identification of performance obligations and licensing from revenue from contracts with customers. The amendments help determine the whether promises to transfer goods or services to a customer are separately identifiable by emphasizing that an entity determines whether the nature of its promise in the contract is to transfer each of the goods or services or whether the promise is to transfer a combined item (or items) to which promised goods and/or services are inputs. In addition, the amendments clarify how to determine whether an entity's promise to grant a license provides a customer with either a right to use the entity's intellectual property or a right to access the entity's intellectual property. Public entities should apply the amendments for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein. Early application for public entities is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently assessing this pronouncement and adoption of this guidance, but it is not expected to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-12 In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , which is intended to improve implementation guidance on certain narrow aspects of Topic 606. The amendments in this ASU: • Clarify how an entity assesses the collectability criterion in Step 1 of Topic 606; • Permit, as an accounting policy election, entities to exclude from the transaction price amounts collected from customers for all sales (and other similar) taxes; • Specify the measurement date of noncash consideration as the date of contract inception; • Clarify when a contract is considered completed for purposes of transition of Topic 606; and • Clarify that an entity that retrospectively applies the guidance in Topic 606 to each prior reporting period is not required to disclose the effect of the accounting change for the period of adoption. However, an entity is still required to disclose the effect of the changes on any prior periods retrospectively adjusted. Public entities should apply the amendments for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein. Early application for public entities is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently assessing this pronouncement and adoption of this guidance, but it is not expected to have a material impact on the Company's financial condition or results of operations. ASU No. 2016-13 In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU , more commonly referred to as Current Expected Credit Losses, or CECL, requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. Public entities should apply the amendments for annual reporting periods beginning after December 15, 2019, including interim reporting periods therein. Early application for public entities is permitted as of annual reporting periods beginning after December 15, 2018, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the ASU on the Company’s financial condition or results of operations.
