Summary of Signficant Accounting Policies
Summary of Significant Accounting Policies Text Block	AUBURN NATIONAL BANCORPORATION, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements NOTE 1 : SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Auburn National Bancorporation, Inc. (the “Company”) is a bank holding company whose primary business is conducted by its wholly-owned subsidiary, AuburnBank (the “Bank”). AuburnBank is a commercial bank located in Auburn , Alabama . The Bank provides a full range of banking services in its primary market area, Lee County , which includes the Auburn-Opelika Metropolitan Statistical Area. Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsi diar ies. Auburn National Bancorporation Capital Trust I is an affiliate of the Company and was included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminat ed in consolidation. 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 liabilitie s and the disclosure of contingent assets and liabilities as of the balance sheet date and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly su sceptible to significant change in the near term include the determination of the allowance for loan losses , fair value measurements , valuation of other real estate owned, and valuation of deferred tax assets. Reclassifications Certain amounts reported in the prior period have been reclassified to conform to the current-period presentation. These reclassifications had no impact on the Company’s previously reported net earnings or total stockholders’ equity . Accounting Standards Adopted in 2015 In the first quarter of 2015 , the Company adopted new guidance related to the following Accounting Standards Updates (“Updates” or “ASUs”): • ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects ; • ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure; • ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ; • ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures; and • ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure . Information about these pronouncements is described in more detail below. ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Project s, amends the criteria a company must meet to elect to account for investments in qualified affordable housing projects using a method other than the cost or equity methods. If the criteria are met, a company is permitted to amortize the initial investment cost in proportion to and over the same period as the total tax benefits the company expects to receive. The amortization of the initial investment cost and tax benefits are t o be recorded in the income tax expense line. The Update also requires new disclosures about all investments in qualified affordable housing projects regardless of the accounting method used. These changes were effective for the Company in the first quarte r of 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure , clarifies the timing of when a creditor is considered to have taken physical possession of residential real estate collateral for a consumer mortgage loan, resulting in the reclassification of the loan receivable to real estate owned. A creditor has taken physical possession o f the property when either (1) the creditor obtains legal title through foreclosure, or (2) the borrower transfers all interests in the property to the creditor via a deed in lieu of foreclosure or a similar legal agreement. The Update also requires disclo sure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in residential real estate mortgage loans that are in the process of foreclosure. These changes were effective for the Company in the first q uarter of 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity , changes the definition and reporting requirements for discontinued operations. Under the new guidance, an entity’s disposal of a component or group of components must be reported in discontinued operations if the disposal is a strategic shift that has or will have a significant eff ect on the entity’s operations and financial results. Major strategic shifts include disposals of a major geographic area or line of business. This guidance also requires new disclosures on discontinued operations. These changes were effective for the Comp any in the first quarter 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures , changes current accountin g and expands secured borrowing accounting for repurchase-to-maturity transactions and repurchase financings. This guidance requires new disclosures for certain repurchase agreements and similar transactions that identify which items are accounted for as secured borrowings and which items are accounted for as sales. These changes were effective for the Company in the first quarter 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 20 14-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure , clarifies how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure. Some creditors reclassify those loans to real estate consistent with other foreclosed loans that do not have guarantees; others reclassify the loans to other receivables. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognize d upon foreclosure if the following conditions are met: (1) The loan has a government guarantee that is not separable from the loan before foreclosure; (2) At the time of foreclosure, the creditor has the intent to convey the real estate property to the gu arantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) At the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclo sure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. These changes were effective for the Company in the first quarter of 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. Cash Equivalents Cash equivalents include c ash on hand, cash items in process of collection, amounts due from banks, including interest bearing deposits with other banks, and federal funds sold. Securities Securities are classified based on management’s intention at the date of purchase. At December 31, 2015 , all of the Company’s securities were classified as availa ble-for-sale. Securities available-for-sale are used as part of the Company’s interest rate risk management strategy, and they may be sold in response to changes in interest rates, changes in prepayment risks or other factors. All securities classified as available-for-sale are recorded at fair value with any unrealized gains and losses reported in accu mulated other comprehensive income , net of the deferred income tax effects. Interest and dividends on securities, including the amortization of premiums and accretion of discounts are recognized in interest income over the anticipated life of the security using the effective interest method, taking into consideration prepayment assumptions. Realized gains and losses from the sale of securities are determined u sing the specific identification method. On a quarterly basis, management makes an assessment to determine whether there have been events or economic circumstances to indicate that a security on which there is an unrealized loss is other-than-temporarily impaired. For equity securities with an unrealized loss, the Company considers many factors including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; and recent events specific to the issuer or industry. Equity securities on which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value with the write-down recorded as a realized loss in securities gain s (losses) , net . For debt securities with an unrealized loss, an other-than-temporary impairment write-down is triggered when (1) the Company has the intent to sell a debt security, (2) it is more likely than not that the Company will be required to sel l the debt security before recovery of its amortized cost basis, or (3) the Company does not expect to recover the entire amortized cost basis of the debt security. If the Company has the intent to sell a debt security or if it is more likely than not that it will be required to sell the debt security before recovery, the other-than-tem porary write-down is equal to the entire difference between the debt security’s amortized cost and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before r ecovery, the other-than-temporary impairment write-down is separated into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings, as a realized loss in securit ies gains (losses), and is the difference between the security’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security’s fair value and the present value of future expected cash flows i s due to factors that are not credit related and is recognized in other comprehensive income, net of applicable taxes. Loans held for sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair va lue in the aggregate . Loan sales are recognized when the transaction closes, the proceeds are collected, and ownership is transferred. Continuing involvement, through the sales agreement, consists of the right to service the loan for a fee for the life o f the loan, if applicable. Gains on the sale of loans held for sale are recorded net of related costs, such as commissions, and reflected as a component of mortgage lending income in the consolidated statements of earnings. In the course of conducting the Bank’s mortgage lending activities of originating mortgage loans and selling those loans in the secondary market, the Bank makes various representations and warranties to the purchaser of the mortgage loans. Every loan closed by the Bank’s mortgage c enter is run through a government agency automated underwriting system. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for th e collateral securing these loans. Failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole re quests) if such failure cannot be cured by the Company within the specified period following discovery. Loans Loans are reported at their outstanding principal balances, net of any unearned income , charge-offs, and any deferred fees or costs on originat ed loans. Interest income is accrued based on the principal balance outstanding. Loan origination fees, net of certain loan origination costs, are deferred and recognized in interest income over the contractual life of the loan using the effective intere st method. Loan commitment fees are generally deferred and amortized on a straight-line basis over the commitment period , which results in a recorded amount that approximates fair value . The accrual of interest on loans is discontinued when there is a sig nificant deterioration in the financial condition of the borrower and full repayment of principal and interest is not expected or the principal or interest is more than 90 days past due, unless the loan is both well-collateralized and in the process of col lection. Generally, all interest accrued but not collected for loans that are placed on nonaccrual status is reversed against current interest income. Interest collections on non accrual loans are generally applied as principal reductions. The Company deter mines past due or delinquency status of a loan based on contractual payment terms. A loan is considered impaired when it is probable the Company will be unable to collect all principal and interest payments due according to the contractual terms of the lo an agreement. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance may be established as part of the allowance for loan losses. Changes to the valuation allowance are recorded as a compone nt of the provision for loan losses. Impaired loans also include troubled debt restructurings (“TDRs”). In the normal course of business, management may grant concessions to borrowers who are experiencing financial difficulty. The concessions granted most frequently for TDRs involve reductions or delays in required payments of principal and interest for a specified time, the rescheduling of payments in accordance with a bankruptcy plan or the charge-off of a portion of the loan. In most cases, the conditio ns of the credit also warrant nonaccrual st atus, even after the restructuring occurs. As part of the credit approval process, the restructured loans are evaluated for adequate collateral protection in determining the appropriate accrual s tatus at the time of restructuring . TDR loans may be returned to accrual status if there has been at least a six-month sustained period of repayment performance by the borrower. Allowance for Loan Losses The allowance for loan losses is maintained at a level that manageme nt believes is adequate to absorb probable losses inherent in the loan portfolio. Loan losses are charged against the allowance when they are known. Subsequent recoveries are credited to the allowance. Management’s determination of the adequacy of the allo wance is based on an evaluation of the portfolio, current economic conditions, growth, composition of the loan portfolio, homogeneous pools of loans, risk ratings of specific loans, historical loan loss factors, identified impaired loans and other factors related to the portfolio. This evaluation is performed quarterly and is inherently subjective, as it requires various material estimates that are susceptible to significant change, including the amounts and timing of future cash flows expected to be receiv ed on any impaired loans. In addition, regulatory agencies, as an integral part of their examination process, will periodically review the Company’s allowance for loan losses, and may require the Company to record additions to the allowance based on their judgment about information available to them at the time of their examinations. Premises and Equipment Land is carried at cost. Buildings and equipment are carried at cost, less accumulated depreciation computed on a straight-line method over the useful lives of the assets or the expected terms of the leases, if shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. Other Real Estate Owned Other real estate owned (“OREO” ) includes properties acquired through, or in lieu of, loan foreclosure that are held for sale and are initially recorded at the lower of the loan’s carrying amount or fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value amount or fair value less cost to sell. Gains or losses realized upon sale of OREO and additional losses related to su bsequent valuation adjustments are determined on a specific property basis and are included as a component of noninterest expense along with holding costs. Nonmarketable equity investments Nonmarketable equity investments include equity securities that are not publicly traded and securities acquired for various purposes . The Bank is required to maintain certain minimum levels of equity investments with certain regulatory and other entities in which the Bank has an ongoing business relationship based on the Bank’s common stock and surplus (with regard to the relationship with the Federal Reserve Bank) or outstanding borrowings (with regard to the relationship with the Federal Home Loan Bank of Atlanta). These securities are accounted for under the cost me thod and are included in other assets. For cost-method investments , on a quarterly basis , the Company evaluates whether an event or change in circumstances has occurred during the reporting period that may have a significant adverse effect on the fair val ue of the investment. If the Company determines that a decline in value is other-than-temporary, the Company will recognize the estimated loss in securities gains (losses), net. Transfers of Financial Assets Transfers of an entire financial asset (i.e. lo an sales), a group of entire financial assets, or a participating interest in an entire financial asset (i.e. loan participations sold) are accounted for as sales when control over the assets have been surrendered. 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 that right) to pledge or exchange the transferred assets, and (3) the Company does not mainta in effective control over the transferred assets through an agreement to repurchase them before their maturity. Mortgage Servicing Rights The Company recognizes as assets the rights to service mortgage loans for others, known as MSRs. The Company determin es the fair value of MSRs at the date the loan is transferred. An estimate of the Company’s MSRs is determined using assumptions that market participants would use in estimating future net servicing income, including estimates of pre p ayment speeds, discou nt rate, default rates, cost to service, escrow account earnings, contractual servicing fee income, ancillary income, and late fees. Subsequent to the date of transfer, the Company has elected to measure its MSRs under the amortization method. Under the amortization method, MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of MSRs is analyzed monthly and is adjusted to reflect changes in prepayment speeds, as well as other factors. MSRs are ev aluated for impairment based on the fair value of those assets. Impairment is determined by stratifying MSRs into groupings based on predominant risk characteristics, such as interest rate and loan type. If, by individual stratum, the carrying amount of the MSRs exceeds fair value, a valuation allowance is established through a charge to earnings. The valuation allowance is adjusted as the fair value changes. MSRs are included in the other assets category in the accompanying consolidated balance sheet s . Derivative Instruments In accordance with Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging , all derivative instruments are recorded on the consolidated balance sheet at their respective fair values. The accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, on the reason for holding it. If the derivative instrument is not designated as part of a hedg ing relationship , the gain or loss on the derivative instrument is recognized in earnings in the period of change. None of the derivatives utilized by the Company have been designated as a hedge. Securities sold under agreements to repurchase Securities sold under agreements to repurchase generally mature less than one year from the transaction date. Securities sold under agreements to repurchase are reflected as a secured borrowing in the accompanying consolidated balance sheets at the amount of cash received in connection with each transaction. Income Taxes Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enac ted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. The net deferred tax asset is reflected as a component of other assets in the accompanying consolidated balance sheets. Income tax expense or benefit for the year is allocated among continuing operations and other comprehensive income (loss), as applicable. The amount allocated to continuing operations is the income tax effect of the pretax income or loss from continuing operations that occu rred during the year, plus or minus income tax effects of ( 1 ) changes in certain circumstances that cause a change in judgment about the realization of deferred tax assets in future years, ( 2 ) changes in income tax laws or rates, and ( 3 ) changes in income tax status, subject to certain exceptions. The amount allocated to other comprehensive income (loss) is related solely to changes in the valuation allowance on items that are normally accounted for in other comprehensive income (loss) such as unrealized g ains or losses on available-for-sale securities. In accordance with ASC 740, Income Taxes , a tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. It is the Compa ny’s policy to recognize interest and penalties related to income tax matters in income tax expense. The Company and its wholly-owned subsidiaries file a consolidated income tax return. Fair Value Measurements ASC 820 , Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in U.S. generally accepted accounting principles and expands disclosures about fair value measurements. ASC 820 applies only to fair-value measurements that are already required or permitted by other accounting standards. The definition of fair value focuses on the exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurem ent date, not the entry price, i.e., the price that would be paid to acquire the asset or received to assume the liability at the measurement date. The statement emphasizes that fair value is a market-based measurement; not an entity-specific measurement. Therefore, the fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. For more information related to fair value measurements, please refer to Note 17 , Fair Value. Subs equent Events The Company has evaluated the effects of events or transactions through the date of this filing that have occurred subsequent to December 31, 2015 . The Company does not believe there are any material subsequent events that would require further recognition or disclosure .

Variable interest entity [Text Block]	NOTE 3 : VARIABLE INTEREST ENTITIES Generally, a variable interest entity (“VIE”) is a corporation, partnership, trust or other legal structure that does not have equity investors with substantive or proportional voting rights or has equity investors that do not provide sufficient financial resources for the entity to support its activ ities. At December 31, 2015 , the Company did not have any consolidated VIEs to disclose but did have one nonconsolidated VIE, discussed below. Trust Preferred Securities The Company owns the common stock of a subsidiary business trust, Auburn National Bancor poration Capital Trust I, which issued mandatorily redeemable preferred capital securities (“trust preferred securities”) in the aggregate of approximately $7.0 million at the time of issuance. This trust meets the definition of a VIE of which the Company is not the primary beneficiary; the trust’s only assets are junior subordinated debentures issued by the Company, which were acquired by the trust using the proceeds from the issuance of the trust preferred securities and common stock. The junior subordina ted debentures of approximately $7.2 million are included in long-term debt and the Company’s equity interest of $0.2 million in the business trust is included in other assets. Interest expense on the junior subordinated debentures is included in interest expense on long-term debt. The following table summarizes VIEs that are not consolidated by the Company as of December 31, 2015 .

The fair value and amortized cost for securities available-for-sale by contractual maturity at December 31, 2015 and 2014 , respectively, are presented below. 1 year 1 to 5 5 to 10 After 10 Fair Gross Unrealized Amortized (Dollars in thousands) or less years years years Value Gains Losses Cost December 31, 2015 Agency obligations (a) $ 5,000 25,852 19,463 9,770 60,085 384 518 $ 60,219 Agency RMBS (a) — 1,623 13,511 95,820 110,954 968 780 110,766 State and political subdivisions — 497 12,094 58,057 70,648 3,022 7 67,633 Total available-for-sale $ 5,000 27,972 45,068 163,647 241,687 4,374 1,305 $ 238,618 December 31, 2014 Agency obligations (a) $ — 30,947 14,869 14,433 60,249 375 830 $ 60,704 Agency RMBS (a) — — 14,523 120,520 135,043 1,597 616 $ 134,062 State and political subdivisions — 502 15,520 56,289 72,311 3,379 34 $ 68,966 Total available-for-sale $ — 31,449 44,912 191,242 267,603 5,351 1,480 $ 263,732 (a) Includes securities issued by U.S. government agencies or government sponsored entities. Securities with aggregate fair values of $133.3 million and $132.2 million at December 31, 2015 and 2014 , respectively, were pledged to secure public deposits, securities sold under agreements to repurchase, Federal Home Loan Bank (“FHLB”) advances, and for other purposes required or permitted by law. Included in other assets on the accompanying consolida ted balance sheets are cost-method investments. The carrying amounts of cost-method investments were $1.4 and $1.6 million at December 31, 2015 and 2014 , respectively. Cost-method investments primarily include non-marketable equity investments, such as FHLB of Atlanta stock and Federal Reserve Bank (“FRB”) stock. Gross Unrealized Losses and Fair Value The fair values and gross unrealized losses on securities at December 31, 2015 and 2014 , respectively, segregated by those securities that have been in an unrealized loss position for less than 12 months and 12 months or more are presented below. Less than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized (Dollars in thousands) Value Losses Value Losses Value Losses December 31, 2015: Agency obligations $ 8,157 2 24,444 516 32,601 $ 518 Agency RMBS 42,345 367 18,184 413 60,529 780 State and political subdivisions 267 1 969 6 1,236 7 Total $ 50,769 370 43,597 935 94,366 $ 1,305 December 31, 2014: Agency obligations $ — — 24,126 830 24,126 $ 830 Agency RMBS 9,078 22 42,744 594 51,822 616 State and political subdivisions 4,257 34 — — 4,257 34 Total $ 13,335 56 66,870 1,424 80,205 $ 1,480 For the securities in the previous table, the Company does not have the intent to sell and has determined it is not more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, which may be maturity. The Company assesses each security for credit impairment. For debt securities, the Company evaluates, where necessary, whether credit impairment exists by comparing the present value of the expected cash flows to the securities’ amortized cost ba sis. For cost-method investments, the Company evaluates whether an event or change in circumstances has occurred during the reporting period that may have a significant adverse effect on the fair value of the investment. In determining whether a loss is temporary, the Company considers all relevant information including: the length of time and the extent to which the fair value has been less than the amortized cost basis; adverse conditions specifically related to the security, an industry, or a geogr aphic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors, including changes in technology or the discontinuance of a segment of the business that may affect the future earnings potential of the issuer or underlying loan obligors of the security or changes in the quality of the credit enhancement); the historical and implied volatility of the fair value of the security ; the payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future; failure of the issuer of the security to make scheduled interest or principal payments; any changes to the rating of t he security by a rating agency; and recoveries or additional declines in fair value subsequent to the balance sheet date. Agency obligations The unrealized losses associated with agency obligations were primarily driven by changes in interest rates and n ot due to the credit quality of the securities. These securities were issued by U.S. government agencies or government-sponsored entities and did not have any credit losses given the explicit government guarantee or other government support. Agency reside ntial mortgage-backed securities (“RMBS”) The unrealized losses associated with agency RMBS were primarily driven by changes in interest rates and not due to the credit quality of the securities. These securities were issued by U.S. government agencies or government-sponsored entities and did not have any credit losses given the explicit government guarantee or other government support. Securities of U.S. states and political subdivisions The unrealized losses associated with securities of U.S. states an d political subdivisions were primarily driven by changes in interest rates and were not due to the credit quality of the securities. Some of these securities are guaranteed by a bond insurer, but management did not rely on the guarantee in making its inve stment decision. These securities will continue to be monitored as part of the Company’s quarterly impairment analysis, but are expected to perform even if the rating agencies reduce the credit rating of the bond insurers. As a result, the Company expects to recover the entire amortized cost basis of these securities. Cost-method investments At December 31, 2015 , cost-method investments with an aggregate cost of $1.4 million were not evaluated for impairment because the Company did not identify any events or changes in circumstances that may have a significant adverse effect on the fair value of these cost-method investments. The carrying values of the Company’s investment securities could decline in the future if the financial condition of an issuer deteriorates and the Company determines it is probable that it will not recover the entire amortized cost basis for the security. As a result, there is a risk that significant other-than-temporary impairment charges may occur in the future. Other-Than-Temporarily Impaired Securities Credit-impaired debt securities are debt securities where the Company has written down the amortized cost basis of a security for other-than-temporary impairment and the credit component of the loss is recognized in earnings. At December 31, 2015 and 2014 , respectively, the Company had no credit-impaired debt securities and there were no additions or reductions in the credit loss component of credit-impaired debt securities during the years ended D ecember 31, 2015 and 2014 , respectively.

At December 31, 2015 , the Company’s geographic loan distribution was concentrated primarily in Lee County, Alabama and surrounding areas. In accordance with ASC 310, Receivables , a portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for loan losses. As part of the Company’s quarterly assessment of the allowance , the loan portfolio is disaggregated into the following portfolio segments: commercial and industrial, construction and land development, commercial real estate, residential real estate and consumer installment. Where appropriate, the Company’s loan port folio segments are further disaggregated into classes. A class is generally determined based on the initial measurement attribute, risk characteristics of the loan, and an entity’s method for monitoring and determining credit risk. The following describe the risk characteristics relevant to each of the portfolio segments. Commercial and industrial (“C&I”) — includes loans to finance business operations, equipment purchases, or other needs for small and medium-sized commercial customers. Also included in t his category are loans to finance agricultural production. Generally the primary source of repayment is the cash flow from business operations and activities of the borrower. Construction and land development (“C&D”) — includes both loans and credit line s for the purpose of purchasing, carrying and developing land into commercial developments or residential subdivisions. Also included are loans and lines for construction of residential, multi-family and commercial buildings. Generally the primary source o f repayment is dependent upon the sale or refinance of the real estate collateral. Commercial real estate (“CRE”) — includes loans disaggregated into two classes: (1) owner occupied and (2) other. Owner occupied – includes loans secured by business faci lities to finance business operations, equipment and owner-occupied facilities primarily for small and medium-sized commercial customers. Generally the primary source of repayment is the cash flow from business operations and activities of the borrower, w ho owns the property. Other – primarily includes loans to finance income-producing commercial and multi-family properties. Loans in this class include loans for neighborhood retail centers, hotels, medical and professional offices, single retail stores, in dustrial buildings, warehouses and apartments leased generally to local businesses and residents. Generally the primary source of repayment is dependent upon income generated from the real estate collateral. The underwriting of these loans takes into consi deration the occupancy and rental rates as well as the financial health of the borrower. R esidential real estate (“RRE”) — includes loans disaggregated into two classes: (1) consumer mortgage and (2) investment property. Consumer mortgage – primaril y i nclude s first or second lien mortgages and home equity lines to consumers that are secured by a primary residence or second home. These loans are underwritten in accordance with the Bank’s general loan policies and procedures which require, among other things, proper documentation of each borrower’s financial condition, satisfactory cre dit history and property value. Investment property – primarily includes loans to finance income-producing 1-4 family residential properties. Generally the primary source of repayment is dependent upon income generated from leasing the property securing the loan. The underwriting of these loans takes into consideration the rental rates as well as the financial health of the borrower. Consumer installment — includes loans to indivi duals both secured by personal property and unsecured. Loans include personal lines of credit, automobile loans, and other retail loans. These loans are underwritten in accordance with the Bank’s general loan policies and procedures which require, among other things, proper documentation of each borrower’s financial condition, satisfactory credit history, and if applicable, property value. The following is a summary of current, accruing past due and nonaccrual loans by portfolio class as of December 31, 2015 and 2014 .

Allowance for Loan Losses The allowance for loan losses as of and for the years ended December 31, 2015 and 2014 , is presented below. Year ended December 31 (In thousands) 2015 2014 Beginning balance $ 4,836 $ 5,268 Charged-off loans (1,114) (808) Recovery of previously charged-off loans 367 326 Net charge-offs (747) (482) Provision for loan losses 200 50 Ending balance $ 4,289 $ 4,836 The Company assesses the adequacy of its allowance for loan losses prior to the end of each calendar quarter. The level of the allowance is based upon management’s evaluation of the loan portfolio, past loan loss experience, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect a borrower’s ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan loss rates and other pertinent factors, including regulatory recommendations. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be receiv ed on impaired loans that may be susceptible to significant change. Loans are charged off, in whole or in part, when management believes that the full collectability of the loan is unlikely. A loan may be partially charged-off after a “confirming event” ha s occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely. The Company deems loans impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts d ue according to the contractual terms of the loan agreement. Collection of all amounts due according to the contractual terms means that both the interest and principal payments of a loan will be collected as scheduled in the loan agreement. An impairment allowance is recognized if the fair value of the loan is less than the recorded investment in the loan. The impairment is recognized through the allowance. Loans that are impaired are recorded at the present value of expected future cash flows discounted at the loan’s effective interest rate, or if the loan is collateral dependent, impairment measurement is based on the fair value of the collateral, less estimated disposal costs. The level of allowance maintained is believed by management to be adequate t o absorb probable losses inherent in the portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off. In assessing the adequacy of the a llowance, the Company also considers the results of its ongoing internal, independent loan review process. The Company’s loan review process assists in determining whether there are loans in the portfolio whose credit quality has weakened over time and eva luating the risk characteristics of the entire loan portfolio. The Company’s loan review process includes the judgment of management, the input from our independent loan reviewers, and reviews that may have been conducted by bank regulatory agencies as par t of their examination process. The Company incorporates loan review results in the determination of whether or not it is probable that it will be able to collect all amounts due according to the contractual terms of a loan. As part of the Company’s quart erly assessment of the allowance, management divides the loan portfolio into five segments: commercial and industrial, construction and land development, commercial real estate, residential real estate, and consumer installment loans. The Company analyzes each segment and estimates an allowance allocation for each loan segment. The allocation of the allowance for loan losses begins with a process of estimating the probable losses inherent for these types of loans. The estimates for these loans are establis hed by category and based on the Company’s internal system of credit risk ratings and historical loss data. The estimated loan loss allocation rate for the Company’s internal system of credit risk grades is based on its experience with similarly graded loa ns. For loan segments where the Company believes it does not have sufficient historical loss data, the Company may make adjustments based, in part, on loss rates of peer bank groups. At December 31, 2015 and 2014 , and for the years then ended, the Co mpany adjusted its historical loss rates for the commercial real estate portfolio segment based, in part, on loss rates of peer bank groups. The estimated loan loss allocation for all five loan portfolio segments is then adjusted for management’s estim ate of probable losses for several “qualitative and environmental” factors. The allocation for qualitative and environmental factors is particularly subjective and does not lend itself to exact mathematical calculation. This amount represents estimated pro bable inherent credit losses which exist, but have not yet been identified, as of the balance sheet date, and are based upon quarterly trend assessments in delinquent and nonaccrual loans, credit concentration changes, prevailing economic conditions, chang es in lending personnel experience, changes in lending policies or procedures and other influencing factors. These qualitative and environmental factors are considered for each of the five loan segments and the allowance allocation, as determined by the pr ocesses noted above, is increased or decreased based on the incremental assessment of these factors. The Company regularly re-evaluates its practices in determining the allowance for loan losses. During 2014, the Company implemented certain refinements to its allowance for loan losses methodology in order to better capture the effects of the most recent economic cycle on the Company’s loan loss experience. Beginning with the quarter ended June 30, 2014, the Company began calculating average losses for all loan segments using a rolling 20 quarter historical period and continued this methodology through December 31, 2015. Prior to June 30, 2014 the Company calculated average losses for all loan segments using a rolling 8 quarter historical period (except fo r commercial real estate loan segment which used a 6 quarter historic period). If the Company continued to calculate average losses for all loan segments other than commercial real estate using a rolling 8 quarter historical period and for the commercial real estate segment using a rolling 6 quarter historical period, the Company’s calculated allowance for loan loss allocation would have decreased by approximately $ 1.0 million at June 30, 2014. Other than the changes discussed above, the Company has not made any material changes to its calculation of historical loss periods that would impact the calculation of the all owance for loan losses or provision for loan losses for the periods included in the accompanying consolidated balance sheets and statements of earnings. The following table details the changes in the allowance for loan losses by portfolio segment for the years ended December 31, 2015 and 2014 .

Credit Quality Indicators The credit quality of the loan portfolio is summarized no less frequently than quarterly using categories similar to the standard asset classification system used by the federal banking agencies. The following table presents credit quality indicators for the loan portfolio segments and classes. These categories are utilized to develop the associated allowance for loan losses using historical losses adjusted for qualitative and environmental factors and are defined as follows: Pass – loans which are well p rotected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral. Special Mention – loans with potential weakness that may, if not reversed or c orrected, weaken the credit or inadequately protect the Company’s position at some future date. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification. Substandard Accruing – loans that exhibit a well-defined weakness which presently jeopardizes debt repayment, even though they are currently performing. These loans are characterized by the distinct possibility that the Company may incur a loss in the future if these weaknesses are not corrected. Nonaccrual – includes loans where management has determined that full payment of principal and interest is in doubt.

Excluding the interest recoveries on these two loans, interest income recognized on impaired loans for 2015 would have been $108 thousand. Troubled Debt Restructurings Impaired loans also include troubled debt restructurings (“TDRs”). In the normal course of business, management may grant concessions to borrowers who are experiencing financial difficulty. A concession may include, but is not limited to, delays in required payments of principal and interest for a specified period, reduction of the stated interest rate of the loan, reduction of accrued interest, extens ion of the maturity date or reduction of the face amount or maturity amount of the debt. A concession has been granted when, as a result of the restructuring, the Bank does not expect to collect all amounts due, including interest at the original stated r ate. A concession may have also been granted if the debtor is not able to access funds elsewhere at a market rate for debt with similar risk characteristics as the restructured debt. In determining whether a loan modification is a TDR, the Company consid ers the individual facts and circumstances surrounding each modification. In determining the appropriate accrual status at the time of restructure, the Company evaluates whether a restructured loan has adequate collateral protection, among other factors. Similar to other impaired loans, TDRs are measured for impairment based on the present value of expected payments using the loan’s original effective interest rate as the discount rate, or the fair value of the collateral, less selling costs if the loa n is collateral dependent. If the recorded investment in the loan exceeds the measure of fair value, impairment is recognized by establishing a valuation allowance as part of the allowance for loan losses or a charge-off to the allowance for loan losses. In periods subsequent to the modification, all TDRs are evaluated individually, including those that have payment defaults, for possible impairment. The following is a summary of accruing and nonaccrual TDRs and the related loan losses, by portfolio segme nt and class.

Mortgage Servicing [Abstract]
Transfers and Servicing of Financial Assets [Text Block]	NOTE 8 : MORTGAGE SERVICING RIGHTS, NET Mortgage servicing rights (“MSRs”) are recognized based on the fair value of the servicing rights on the date the corresponding mortgage loans are sold. An estimate of the Company’s MSRs is determined using assumptions that market participants would use in estimating future net servicing income, including estimates of prepayment speeds, discount rate, default rates, cost to service, escrow account earnings, contractual servicing fee income, ancillary income, and late fees. Subsequent to the date of transfer, the Company has elected to measure its MSRs under the amortization method. Under the amortization method, MSRs are amortized in proportion to, and over the period of, estimated net servicing income. Serv icing fee income is recorded net of related amortization expense and recognized in earnings as part of mortgage lending income. The Company has recorded MSRs related to loans sold without recourse to Fannie Mae. The Company generally sells conforming, f ixed-rate, closed-end, residential mortgages to Fannie Mae. MSRs are included in other assets on the accompanying consolidated balance sheets. The Company evaluates MSRs for impairment on a quarterly basis. Impairment is determined by stratifying MSRs i nto groupings based on predominant risk characteristics, such as interest rate and loan type. If, by individual stratum, the carrying amount of the MSRs exceeds fair value, a valuation allowance is established. The valuation allowance is adjusted as the fair value changes. Changes in the valuation allowance are recognized in earnings as a component of mortgage lending income. The following table details the changes in amortized MSRs and the related valuation allowance for the years ended December 31, 2015 and 2014 .

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax pl anning strategies in making this assessment. Based upon the level of historical taxable income and projection for future taxable income over the periods which the temporary differences resulting in the remaining deferred tax assets are deductible, manageme nt believes it is more-likely-than-not that the Company will realize the benefits of these deductible differences at December 31, 2015 . The amount of the deferred tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income are reduced. The change in the net deferred tax asset for the years ended December 31, 2015 and 2014 , is presented below.

This section also provides guidance on the de-recognition, measurement, and classification of income tax uncertainties in interim periods. As of December 31, 2015 , the Company had no unrecognized tax benefits related to federal or state income tax matters. The Company does not anticipate any material increase or decrease in u nrecognized tax benefits during 2016 relative to any tax positions taken prior to December 31, 2015 . As of December 31, 2015 , the Company has accrued no interest and no penalties related to uncertain tax positions.

Derivative instruments and hedging activities disclosure abstract
Derivative Instruments And Hedging Activities Disclosure Text Block	NOTE 15 : DERIVATIVE INSTRUMENTS Financial derivatives are reported at fair value in other assets or other liabilities on the accompanying Consolidated Balance Sheets. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as part of a hedging relationship, the gain or loss is recognized in current earnings within other noninterest income on the accompanying Consolidated Stat ements of Earnings. From time to time, the Company may enter into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. Upon entering into these swaps, the Company enters into offsetting positions in order to min imize the risk to the Company. These swaps qualify as derivatives, but are not designated as hedging instruments. At December 31, 2015 and December 31, 2014 , the Company had no derivative contracts to assist in managing its own interest rate sensitivity. Interest rate swap ag reements involve the risk of dealing with counterparties and their ability to meet contractual terms. When the fair value of a derivative instrument is positive, this generally indicates that the counterparty or customer owes the Company, and results in cr edit risk to the Company. When the fair value of a derivative instrument contract is negative, the Company owes the customer or counterparty and therefore, has no credit risk. A summary of the Company’s interest rate swaps as of and for the years ended December 31, 2015 and 2014 is presented below.

The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments. At December 31, 2015 and 2014 , the following financial instruments were outstanding whose contract amount represents credit risk: December 31 (Dollars in thousands) 2015 2014 Commitments to extend credit $ 52,230 $ 49,824 Standby letters of credit 8,221 8,337 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for lines of credit may expire without being drawn upon. Therefore, total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is base d on management’s credit evaluation of the customer. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essenti ally the same as that involved in extending loan facilities to customers. The Company holds various assets as collateral, including accounts receivable, inventory, equipment, marketable securities, and property to support those commitments for which colla teral is deemed necessary. The Company has recorded a liability for the estimated fair value of these standby letters of credit in the amount of $69 thousand and $72 thousand at December 31, 2015 and 2014 , respectively. Other Commitments Minimum lease payments under leases classified as operating leases due in each of the five years subsequent to December 31, 2015 , are as follows: 2016, $220 thousand; 2017, $125 thousand; 2018, $35 thousand; 2019, $30 thousand; 2020, $3 thousand. Contingen t Liabilities The Company and the Bank are involved in various legal proceedings, arising in connection with their business. In the opinion of management, based upon consultation with legal counsel, the ultimate resolution of these proceeding will not ha ve a material adverse effect upon the consolidated financial condition or results of operations of the Company and the Bank.

Fair Value Disclosures [Abstract]
Fair Value Disclosures Text Block	NOTE 17 : FAIR VALUE Fair Value Hierarchy “Fair value” is defined by ASC 820, Fair Value Measurements and Disclosures , as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for an asset or liability at the measurement date. GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1—inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. Level 2—inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs that are observable fo r the asset or liability, either directly or indirectly. Level 3—inputs to the valuation methodology are unobservable and reflect the Company’s own assumptions about the inputs market participants would use in pricing the asset or liability. Level c hanges in fair value measurements Transfers between levels of the fair value hierarchy are generally recognized at the end of the reporting period. The Company monitors the valuation techniques utilized for each category of financial assets and liabilit ies to ascertain when transfers between levels have been affected. The nature of the Company’s financial assets and liabilities generally is such that transfers in and out of any level are expected to be infrequent. For the years ended December 31, 2015 and 2014 , there were no transfers between levels and no changes in valuation techniques for the Company’s financial assets and liabilities. Assets and liabilities measured at fair value on a recurring basis Securities available-for-sale Fair values of securiti es available for sale were primarily measured using Level 2 inputs. For these securities, the Company obtains pricing from third party pricing services. These third party pricing services consider observable data that may include broker/dealer quotes, ma rket spreads, cash flows, market consensus prepayment speeds, benchmark yields, reported trades for similar securities, credit information and the securities’ terms and conditions. On a quarterly basis, management reviews the pricing received from the thi rd party pricing services for reasonableness given current market conditions. As part of its review, management may obtain non-binding third party broker quotes to validate the fair value measurements. In addition, management will periodically submit pri cing provided by the third party pricing services to another independent valuation firm on a sample basis. This independent valuation firm will compare the price provided by the third party pricing service with its own price and will review the significan t assumptions and valuation methodologies used with management. Interest rate swap agreements The carrying amount of interest rate swap agreements was included in other assets and accrued expenses and other liabilities on the accompanying consolidated balance sheets. The fair value measurements for our interest rate swap agreements were based on information obtained from a third party bank. This information is periodically tested by the Company and validated against other third party valuations. If needed, other third party market participants may be utilized to corroborate the fair value measurements for our interest rate swap agreements. The Company classified these derivative assets and liabilities within Level 2 of the valuation hierarchy. These swaps qualify as derivatives, but are not designated as hedging instruments. The following table presents the balances of the assets and liabilities measured at fair value on a recurring basis as of December 31, 2015 and 2014 , respectively, by caption, on th e accompanying consolidated balance sheets by ASC 820 valuation hierarchy (as described above). Quoted Prices in Significant Active Markets Other Significant for Observable Unobservable Identical Assets Inputs Inputs (Dollars in thousands) Amount (Level 1) (Level 2) (Level 3) December 31, 2015: Securities available-for-sale: Agency obligations $ 60,085 — 60,085 — Agency RMBS 110,954 — 110,954 — State and political subdivisions 70,648 — 70,648 — Total securities available-for-sale 241,687 — 241,687 — Other assets (1) 440 — 440 — Total assets at fair value $ 242,127 — 242,127 — Other liabilities (1) 440 — 440 — Total liabilities at fair value $ 440 — 440 — December 31, 2014: Securities available-for-sale: Agency obligations $ 60,249 — 60,249 — Agency RMBS 135,043 — 135,043 — State and political subdivisions 72,311 — 72,311 — Total securities available-for-sale 267,603 — 267,603 — Other assets (1) 634 — 634 — Total assets at fair value $ 268,237 — 268,237 — Other liabilities (1) 634 — 634 — Total liabilities at fair value $ 634 — 634 — (1) Represents the fair value of interest rate swap agreements. Assets and liabilities measured at fair value on a nonrecurring basis Loans held for sale Loans held for sale are carried at the lower of cost or fair value. Fair values of loans held for sale are determined using quoted market secondary market prices for similar loans. Loans held for sale are classified within Level 2 of the fair value hierarchy. Impaired Loans Loans considered impaired under ASC 310-10-35, Receivables , are loans for which, based on current information and events, it is probable that the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreement. Impaired loans can be measured based on the present value of expected payments using the loan’s original effective r ate as the discount rate, the loan’s observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent. The fair value of impaired loans were primarily measured based on the value of the collateral securi ng these loans. Impaired loans are classified within Level 3 of the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory, and/or accounts receivable. The Company determines the value of the collateral based on independent appraisals performed by qualified licensed appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised values are discounted for c osts to sell and may be discounted further based on management’s historical knowledge, changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such d iscounts by management are subjective and are typically significant unobservable inputs for determining fair value. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the sa me factors discussed above. Other real estate owned Other real estate owned, consisting of properties obtained through foreclosure or in satisfaction of loans, are initially recorded at the lower of the loan’s carrying amount or the fair value less cost s to sell upon transfer of the loans to other real estate. Subsequently, other real estate is carried at the lower of carrying value or fair value less costs to sell. Fair values are generally based on third party appraisals of the property and are class ified within Level 3 of the fair value hierarchy. The appraisals are sometimes further discounted based on management’s historical knowledge, and/or changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts are typically significant unobservable inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less costs to sell, a loss is recognized in nonint erest expense. Mortgage servicing rights, net M ortgage servicing rights, net, included in other assets on the accompanying consolidated balance sheets, are carried at the lower of cost or estimated fair value. MSRs do not trade in an active market with readily observable prices. To determine the fair value of MSRs, the Company engages an independent third party. The independent third party’s valuation model calculates the present value of estimated future net servicing income using assumptions that mar ket participants would use in estimating future net servicing income, including estimates of prepayment speeds, discount rate, default rates, cost to service, escrow account earnings, contractual servicing fee income, ancillary income, and late fees. Peri odically, the Company will review broker surveys and other market research to validate significant assumptions used in the model. The significant unobservable inputs include prepayment speeds or the constant prepayment rate (“CPR”) and the weighted averag e discount rate. Because the valuation of MSRs requires the use of significant unobservable inputs, all of the Company’s MSRs are classified within Level 3 of the valuation hierarchy. The following table presents the balances of the assets and liabilities measured at fair value on a nonrecurring basis as of December 31, 2015 and 2014 , respectively, by caption, on the accompanying consolidated balance sheets and by ASC 820 valuation hierarchy (as described above): Quoted Prices in Active Markets Other Significant for Observable Unobservable Identical Assets Inputs Inputs (Dollars in thousands) Amount (Level 1) (Level 2) (Level 3) December 31, 2015: Loans held for sale $ 1,540 — 1,540 — Loans, net (1) 3,286 — — 3,286 Other real estate owned 252 — — 252 Other assets (2) 2,316 — — 2,316 Total assets at fair value $ 7,394 — 1,540 5,854 December 31, 2014: Loans held for sale $ 1,974 — 1,974 — Loans, net (1) 3,077 — — 3,077 Other real estate owned 534 — — 534 Other assets (2) 2,388 — — 2,388 Total assets at fair value $ 7,973 — 1,974 5,999 (1) Loans considered impaired under ASC 310-10-35 Receivables. This amount reflects the recorded investment in impaired loans, net of any related allowance for loan losses. (2) Represents MSRs, net, carried at lower of cost or estimated fair value. At December 31, 2015 and 2014 and for the years then ended, the Company had no Level 3 assets measured at fair value on a recurring basis. For Level 3 assets measured at fair value on a non-recurring basis as of December 31, 2015 , the significant unobservable inputs used in the fair value measurements are presented below. Weighted Carrying Average (Dollars in thousands) Amount Valuation Technique Significant Unobservable Input of Input Nonrecurring: Impaired loans $ 3,286 Appraisal Appraisal discounts (%) 25.7 % Other real estate owned 252 Appraisal Appraisal discounts (%) 6.0 % Mortgage servicing rights, net 2,316 Discounted cash flow Prepayment speed or CPR (%) 10.0 % Discount rate (%) 10.0 % Fair Value of Financial Instruments ASC 825, Financial Instruments , requires disclosure of fair value information about financial instruments, whether or not recognized on the face of the balance sheet, for which it is practicable to estimate that value. The assumptions used in the estimation of the fair value of the Company’s financial instruments are explained below. Where quoted market prices are not available, fair values are based on estimates using discounted cash flow analyses. Discounted cash flows can be significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. The following fair value estima tes cannot be substantiated by comparison to independent markets and should not be considered representative of the liquidation value of the Company’s financial instruments, but rather are a good-faith estimate of the fair value of financial instruments he ld by the Company. ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments: Loans, net Fair values for loans were calculated using discounted cash flows. The discount rates reflected current rates at which similar loans would be made for the same remaining maturities. This method of estimating fair value does not incorporate th e exit-price concept of fair value prescribed by ASC 820 and generally produces a higher value than an exit-price approach. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. Loans held for sale Fair values of loans held for sale are determined using quoted market secondary market prices for similar loans . Time Deposits Fair values for time deposits were estimated using discounted cash flows. The discount rates were based on rates currently offer ed for deposits with similar remaining maturities. Long-term debt The fair value of the Company’s fixed rate long-term debt is estimated using discounted cash flows based on estimated current market rates for similar types of borrowing arrangements. The carrying amount of the Company’s variable rate long-term debt approximates its fair value. The carrying value, related estimated fair value, and placement in the fair value hierarchy of the Company’s financial instruments at December 31, 2015 and 2014 are pre sented below. This table excludes financial instruments for which the carrying amount approximates fair value. Financial assets for which fair value approximates carrying value included cash and cash equivalents. Financial liabilities for which fair val ue approximates carrying value included noninterest-bearing demand, interest-bearing demand, and savings deposits due to these products having no stated maturity. In addition, financial liabilities for which fair value approximates carrying value included overnight borrowings such as federal funds purchased and securities sold under agreements to repurchase.

Related Party Transactions Disclosure [Text Block]	NOTE 18 : RELATED PARTY TRANSACTIONS A former director who retired from the Company’s board of directors in October 2015, is an officer in a construction company that the Company contracted with in 2015 and 2014 for limited renovations at the Bank’s operations center, the build out of leasehold improvements in connection with a relocation of a bank branch, and for construction of a new branch facility located in Auburn, Alabama. Total payments made to the construction company under the terms of these contracts were $1.2 million and $0.1 million for the years ended December 31, 2015 and 2014, respectively. The Bank has made, and expects in the future to continue to make in the ordinary course of business, loans to directors and executive officers of the Company, the Bank, and their affiliates. In management’s opinion, these loans were made in the ordinary course of business at normal credit terms, including interest rate and collateral requirements, and do not represent more than normal credit risk. An analysis of such outstanding loans is pres ented below.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	NOTE 19 : REGULATORY RESTRICTIONS AND CAPITAL RATIOS The Company and the Bank are subject to various regulatory capital requirements and policies administered by federal and State of Alabama banking regulators. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a material effect on the consolidated financial statements. Under capital adequacy guidelines and the regulatory fr amework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and Bank’s assets, liabilities, and certain off–balance sheet items as calculated under regulatory acco unting practices. The Company’s and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors, including anticipated capital needs. Supervisory assessments o f capital adequacy may differ significantly from conclusions based solely upon risk-based capital ratios. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (s et forth in the table below) common equity Tier 1 ratio, Tier 1 leverage ratio, Tier 1 risk-based ratio and total risk-based ratio. Management believes, as of December 31, 2015 , that the Company and the Bank meet all capital adequacy requirements to w hich they are subject. As of December 31, 2015 , the Bank is “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” the Bank must maintain minimum common equity Tier 1, total risk- based, Tier 1 risk- based, and Tier 1 leverage ratios as set forth in the table. Management has not received any notification from the Company’s or the Bank's regulators that changes the Bank’s regulatory capital status. The actual capital amounts and ratios and the aforementioned minimums as of December 31, 2015 and 2014 are presented below. Minimum for capital Minimum to be Actual adequacy purposes well capitalized (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio At December 31, 2015: Common Equity Tier 1 Capital Auburn National Bancorporation $ 77,714 15.28 % $ 22,886 4.50 % N/A N/A AuburnBank 82,848 16.26 22,933 4.50 $ 33,125 6.50 Tier 1 Leverage Capital Auburn National Bancorporation $ 84,268 10.35 % $ 32,553 4.00 % N/A N/A AuburnBank 82,848 10.19 32,519 4.00 $ 40,649 5.00 % Tier 1 Risk-Based Capital Auburn National Bancorporation $ 84,268 16.57 % $ 30,515 6.00 % N/A N/A AuburnBank 82,848 16.26 30,577 6.00 $ 40,769 8.00 % Total Risk-Based Capital Auburn National Bancorporation $ 88,682 17.44 % $ 40,687 8.00 % N/A N/A AuburnBank 87,262 17.12 40,769 8.00 $ 50,962 10.00 % At December 31, 2014: Tier 1 Leverage Capital Auburn National Bancorporation $ 80,356 10.32 % $ 31,133 4.00 % N/A N/A AuburnBank 78,968 10.16 31,099 4.00 $ 38,873 5.00 % Tier 1 Risk-Based Capital Auburn National Bancorporation $ 80,356 17.45 % $ 18,419 4.00 % N/A N/A AuburnBank 78,968 17.11 18,463 4.00 $ 27,695 6.00 % Total Risk-Based Capital Auburn National Bancorporation $ 85,356 18.54 % $ 36,839 8.00 % N/A N/A AuburnBank 83,968 18.19 36,927 8.00 $ 46,158 10.00 % Dividends paid by the Bank are a principal source of funds available to the Company for payment of dividends to its stockholders and for other needs. Applicable federal and state statutes and regulations impose restrictions on the amounts of dividends that may be declared by the subsidiary bank. State law and Federal Reserve policy restrict the Bank from declaring dividends in excess of the sum of the current year’s earnings plus the retained net earnings from the preceding two years without prior appro val. In addition to the formal statutes and regulations, regulatory authorities also consider the adequacy of the Bank’s total capital in relation to its assets, deposits, and other such items. Capital adequacy considerations could further limit the availa bility of dividends from the Bank. At December 31, 2015 , the Bank could have declared additional dividends of approximately $12.3 million without prior approval of regulatory authorities. As a result of this limitation, approximately $73.2 million of th e Company’s investment in the Bank was restricted from transfer in the form of dividends.

Summary of Signficant Accounting Policies
Nature of Business Policy	NOTE 1 : SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Auburn National Bancorporation, Inc. (the “Company”) is a bank holding company whose primary business is conducted by its wholly-owned subsidiary, AuburnBank (the “Bank”). AuburnBank is a commercial bank located in Auburn , Alabama . The Bank provides a full range of banking services in its primary market area, Lee County , which includes the Auburn-Opelika Metropolitan Statistical Area.
Basis of Presentation Policy	Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsi diar ies. Auburn National Bancorporation Capital Trust I is an affiliate of the Company and was included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminat ed in consolidation.
Use of Estimates Policy	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 liabilitie s and the disclosure of contingent assets and liabilities as of the balance sheet date and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly su sceptible to significant change in the near term include the determination of the allowance for loan losses , fair value measurements , valuation of other real estate owned, and valuation of deferred tax assets.
Reclassifications Policy	Reclassifications Certain amounts reported in the prior period have been reclassified to conform to the current-period presentation. These reclassifications had no impact on the Company’s previously reported net earnings or total stockholders’ equity
Accounting Standards Adopted in 2014	Accounting Standards Adopted in 2015 In the first quarter of 2015 , the Company adopted new guidance related to the following Accounting Standards Updates (“Updates” or “ASUs”): • ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects ; • ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure; • ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ; • ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures; and • ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure . Information about these pronouncements is described in more detail below. ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Project s, amends the criteria a company must meet to elect to account for investments in qualified affordable housing projects using a method other than the cost or equity methods. If the criteria are met, a company is permitted to amortize the initial investment cost in proportion to and over the same period as the total tax benefits the company expects to receive. The amortization of the initial investment cost and tax benefits are t o be recorded in the income tax expense line. The Update also requires new disclosures about all investments in qualified affordable housing projects regardless of the accounting method used. These changes were effective for the Company in the first quarte r of 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure , clarifies the timing of when a creditor is considered to have taken physical possession of residential real estate collateral for a consumer mortgage loan, resulting in the reclassification of the loan receivable to real estate owned. A creditor has taken physical possession o f the property when either (1) the creditor obtains legal title through foreclosure, or (2) the borrower transfers all interests in the property to the creditor via a deed in lieu of foreclosure or a similar legal agreement. The Update also requires disclo sure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in residential real estate mortgage loans that are in the process of foreclosure. These changes were effective for the Company in the first q uarter of 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity , changes the definition and reporting requirements for discontinued operations. Under the new guidance, an entity’s disposal of a component or group of components must be reported in discontinued operations if the disposal is a strategic shift that has or will have a significant eff ect on the entity’s operations and financial results. Major strategic shifts include disposals of a major geographic area or line of business. This guidance also requires new disclosures on discontinued operations. These changes were effective for the Comp any in the first quarter 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures , changes current accountin g and expands secured borrowing accounting for repurchase-to-maturity transactions and repurchase financings. This guidance requires new disclosures for certain repurchase agreements and similar transactions that identify which items are accounted for as secured borrowings and which items are accounted for as sales. These changes were effective for the Company in the first quarter 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company. ASU 20 14-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure , clarifies how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure. Some creditors reclassify those loans to real estate consistent with other foreclosed loans that do not have guarantees; others reclassify the loans to other receivables. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognize d upon foreclosure if the following conditions are met: (1) The loan has a government guarantee that is not separable from the loan before foreclosure; (2) At the time of foreclosure, the creditor has the intent to convey the real estate property to the gu arantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) At the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclo sure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. These changes were effective for the Company in the first quarter of 2015. Adoption of this ASU did not have a material impact on the consolidated financial statements of the Company.
Cash Equivalents Policy	Cash Equivalents Cash equivalents include c ash on hand, cash items in process of collection, amounts due from banks, including interest bearing deposits with other banks, and federal funds sold.
Securities Policy	Securities Securities are classified based on management’s intention at the date of purchase. At December 31, 2015 , all of the Company’s securities were classified as availa ble-for-sale. Securities available-for-sale are used as part of the Company’s interest rate risk management strategy, and they may be sold in response to changes in interest rates, changes in prepayment risks or other factors. All securities classified as available-for-sale are recorded at fair value with any unrealized gains and losses reported in accu mulated other comprehensive income , net of the deferred income tax effects. Interest and dividends on securities, including the amortization of premiums and accretion of discounts are recognized in interest income over the anticipated life of the security using the effective interest method, taking into consideration prepayment assumptions. Realized gains and losses from the sale of securities are determined u sing the specific identification method. On a quarterly basis, management makes an assessment to determine whether there have been events or economic circumstances to indicate that a security on which there is an unrealized loss is other-than-temporarily impaired. For equity securities with an unrealized loss, the Company considers many factors including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; and recent events specific to the issuer or industry. Equity securities on which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value with the write-down recorded as a realized loss in securities gain s (losses) , net . For debt securities with an unrealized loss, an other-than-temporary impairment write-down is triggered when (1) the Company has the intent to sell a debt security, (2) it is more likely than not that the Company will be required to sel l the debt security before recovery of its amortized cost basis, or (3) the Company does not expect to recover the entire amortized cost basis of the debt security. If the Company has the intent to sell a debt security or if it is more likely than not that it will be required to sell the debt security before recovery, the other-than-tem porary write-down is equal to the entire difference between the debt security’s amortized cost and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before r ecovery, the other-than-temporary impairment write-down is separated into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings, as a realized loss in securit ies gains (losses), and is the difference between the security’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security’s fair value and the present value of future expected cash flows i s due to factors that are not credit related and is recognized in other comprehensive income, net of applicable taxes.
Loans Held for Sale Policy	Loans held for sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair va lue in the aggregate . Loan sales are recognized when the transaction closes, the proceeds are collected, and ownership is transferred. Continuing involvement, through the sales agreement, consists of the right to service the loan for a fee for the life o f the loan, if applicable. Gains on the sale of loans held for sale are recorded net of related costs, such as commissions, and reflected as a component of mortgage lending income in the consolidated statements of earnings. In the course of conducting the Bank’s mortgage lending activities of originating mortgage loans and selling those loans in the secondary market, the Bank makes various representations and warranties to the purchaser of the mortgage loans. Every loan closed by the Bank’s mortgage c enter is run through a government agency automated underwriting system. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for th e collateral securing these loans. Failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole re quests) if such failure cannot be cured by the Company within the specified period following discovery.
Loans Policy	Loans Loans are reported at their outstanding principal balances, net of any unearned income , charge-offs, and any deferred fees or costs on originat ed loans. Interest income is accrued based on the principal balance outstanding.
Loans, Origination Fees Policy	Loan origination fees, net of certain loan origination costs, are deferred and recognized in interest income over the contractual life of the loan using the effective intere st method. Loan commitment fees are generally deferred and amortized on a straight-line basis over the commitment period , which results in a recorded amount that approximates fair value .
Loans, Nonacrrual Policy	The accrual of interest on loans is discontinued when there is a sig nificant deterioration in the financial condition of the borrower and full repayment of principal and interest is not expected or the principal or interest is more than 90 days past due, unless the loan is both well-collateralized and in the process of col lection. Generally, all interest accrued but not collected for loans that are placed on nonaccrual status is reversed against current interest income. Interest collections on non accrual loans are generally applied as principal reductions. The Company deter mines past due or delinquency status of a loan based on contractual payment terms.
Loans, Impaired Policy	A loan is considered impaired when it is probable the Company will be unable to collect all principal and interest payments due according to the contractual terms of the lo an agreement. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance may be established as part of the allowance for loan losses. Changes to the valuation allowance are recorded as a compone nt of the provision for loan losses.
Loans, Troubled Debt Restructuring Policy	Impaired loans also include troubled debt restructurings (“TDRs”). In the normal course of business, management may grant concessions to borrowers who are experiencing financial difficulty. The concessions granted most frequently for TDRs involve reductions or delays in required payments of principal and interest for a specified time, the rescheduling of payments in accordance with a bankruptcy plan or the charge-off of a portion of the loan. In most cases, the conditio ns of the credit also warrant nonaccrual st atus, even after the restructuring occurs. As part of the credit approval process, the restructured loans are evaluated for adequate collateral protection in determining the appropriate accrual s tatus at the time of restructuring . TDR loans may be returned to accrual status if there has been at least a six-month sustained period of repayment performance by the borrower.
Allowance for Loan Losses Policy	Allowance for Loan Losses The allowance for loan losses is maintained at a level that manageme nt believes is adequate to absorb probable losses inherent in the loan portfolio. Loan losses are charged against the allowance when they are known. Subsequent recoveries are credited to the allowance. Management’s determination of the adequacy of the allo wance is based on an evaluation of the portfolio, current economic conditions, growth, composition of the loan portfolio, homogeneous pools of loans, risk ratings of specific loans, historical loan loss factors, identified impaired loans and other factors related to the portfolio. This evaluation is performed quarterly and is inherently subjective, as it requires various material estimates that are susceptible to significant change, including the amounts and timing of future cash flows expected to be receiv ed on any impaired loans. In addition, regulatory agencies, as an integral part of their examination process, will periodically review the Company’s allowance for loan losses, and may require the Company to record additions to the allowance based on their judgment about information available to them at the time of their examinations.
Premises and Equipment Policy	Premises and Equipment Land is carried at cost. Buildings and equipment are carried at cost, less accumulated depreciation computed on a straight-line method over the useful lives of the assets or the expected terms of the leases, if shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured.
Other Real Estate Owned Policy	Other Real Estate Owned Other real estate owned (“OREO” ) includes properties acquired through, or in lieu of, loan foreclosure that are held for sale and are initially recorded at the lower of the loan’s carrying amount or fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value amount or fair value less cost to sell. Gains or losses realized upon sale of OREO and additional losses related to su bsequent valuation adjustments are determined on a specific property basis and are included as a component of noninterest expense along with holding costs.
Nonmarketable Equity Investments Policy	Nonmarketable equity investments Nonmarketable equity investments include equity securities that are not publicly traded and securities acquired for various purposes . The Bank is required to maintain certain minimum levels of equity investments with certain regulatory and other entities in which the Bank has an ongoing business relationship based on the Bank’s common stock and surplus (with regard to the relationship with the Federal Reserve Bank) or outstanding borrowings (with regard to the relationship with the Federal Home Loan Bank of Atlanta). These securities are accounted for under the cost me thod and are included in other assets. For cost-method investments , on a quarterly basis , the Company evaluates whether an event or change in circumstances has occurred during the reporting period that may have a significant adverse effect on the fair val ue of the investment. If the Company determines that a decline in value is other-than-temporary, the Company will recognize the estimated loss in securities gains (losses), net.
Transfers and Servicing of Financial Assets, Policy	Transfers of Financial Assets Transfers of an entire financial asset (i.e. lo an sales), a group of entire financial assets, or a participating interest in an entire financial asset (i.e. loan participations sold) are accounted for as sales when control over the assets have been surrendered. 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 that right) to pledge or exchange the transferred assets, and (3) the Company does not mainta in effective control over the transferred assets through an agreement to repurchase them before their maturity.
Mortgage Servicing Rights Policy	Mortgage Servicing Rights The Company recognizes as assets the rights to service mortgage loans for others, known as MSRs. The Company determin es the fair value of MSRs at the date the loan is transferred. An estimate of the Company’s MSRs is determined using assumptions that market participants would use in estimating future net servicing income, including estimates of pre p ayment speeds, discou nt rate, default rates, cost to service, escrow account earnings, contractual servicing fee income, ancillary income, and late fees. Subsequent to the date of transfer, the Company has elected to measure its MSRs under the amortization method. Under the amortization method, MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of MSRs is analyzed monthly and is adjusted to reflect changes in prepayment speeds, as well as other factors. MSRs are ev aluated for impairment based on the fair value of those assets. Impairment is determined by stratifying MSRs into groupings based on predominant risk characteristics, such as interest rate and loan type. If, by individual stratum, the carrying amount of the MSRs exceeds fair value, a valuation allowance is established through a charge to earnings. The valuation allowance is adjusted as the fair value changes. MSRs are included in the other assets category in the accompanying consolidated balance sheet s .
Derivative Instruments Policy	Derivative Instruments In accordance with Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging , all derivative instruments are recorded on the consolidated balance sheet at their respective fair values. The accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, on the reason for holding it. If the derivative instrument is not designated as part of a hedg ing relationship , the gain or loss on the derivative instrument is recognized in earnings in the period of change. None of the derivatives utilized by the Company have been designated as a hedge.
Securities Sold Under Agreements to Repurchase Policy	Securities sold under agreements to repurchase Securities sold under agreements to repurchase generally mature less than one year from the transaction date. Securities sold under agreements to repurchase are reflected as a secured borrowing in the accompanying consolidated balance sheets at the amount of cash received in connection with each transaction.
Income Taxes Policy	Income Taxes Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enac ted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. The net deferred tax asset is reflected as a component of other assets in the accompanying consolidated balance sheets. Income tax expense or benefit for the year is allocated among continuing operations and other comprehensive income (loss), as applicable. The amount allocated to continuing operations is the income tax effect of the pretax income or loss from continuing operations that occu rred during the year, plus or minus income tax effects of ( 1 ) changes in certain circumstances that cause a change in judgment about the realization of deferred tax assets in future years, ( 2 ) changes in income tax laws or rates, and ( 3 ) changes in income tax status, subject to certain exceptions. The amount allocated to other comprehensive income (loss) is related solely to changes in the valuation allowance on items that are normally accounted for in other comprehensive income (loss) such as unrealized g ains or losses on available-for-sale securities. In accordance with ASC 740, Income Taxes , a tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. It is the Compa ny’s policy to recognize interest and penalties related to income tax matters in income tax expense. The Company and its wholly-owned subsidiaries file a consolidated income tax return.
Income Taxes, Uncertainties Policy	In accordance with ASC 740, Income Taxes , a tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. It is the Compa ny’s policy to recognize interest and penalties related to income tax matters in income tax expense. The Company and its wholly-owned subsidiaries file a consolidated income tax return.
Fair Value Measurements Policy	Fair Value Measurements ASC 820 , Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in U.S. generally accepted accounting principles and expands disclosures about fair value measurements. ASC 820 applies only to fair-value measurements that are already required or permitted by other accounting standards. The definition of fair value focuses on the exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurem ent date, not the entry price, i.e., the price that would be paid to acquire the asset or received to assume the liability at the measurement date. The statement emphasizes that fair value is a market-based measurement; not an entity-specific measurement. Therefore, the fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. For more information related to fair value measurements, please refer to Note 17 , Fair Value.
Subsequent Events Policy	Subs equent Events The Company has evaluated the effects of events or transactions through the date of this filing that have occurred subsequent to December 31, 2015 . The Company does not believe there are any material subsequent events that would require further recognition or disclosure .
