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 subsidiary, AuburnBank. Significant intercompany transactions are eliminated 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 liabilities 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 susceptible 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. Correction of Accounting Errors Income tax benefit for the year ended December 31, 2009 included a $281 thousand tax benefit related to the correction of an error in prior periods that resulted from the incorrect calculation of tax basis for certain available-for-sale securities, primarily related to periods prior to January 1, 2007. Management believes the impact of th is correction is not material to current or prior period financial statements and the Company's Audit Committee of the Board of Directors, based on information reviewed by management with the Audit Committee, concurs with management's conclusion. Reclassifications Certain amounts reported in prior periods have been reclassified to conform to the current-period presentation. These reclassifications had no effect on the Company's previously reported net earnings or total stockholders' equity. Accounting Standards Adopted in 201 1 In the first quarter of 2011, the Company adopted new guidance related to the following Codification topic: Accounting Standards Update (“ASU”) 2010-06, Improving Disclosures about Fair Value Measurements. In the third quarter of 2011, the Company adopted new guidance related to the following Codification topic: ASU 2011-02, A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring. Information about these pronouncements is described in more detail below. ASU 2010-06, Improving Disclosures about Fair Value Measurements, amends the disclosure requirements for fair value measurements. Companies are required to disclose significant transfers in and out of Levels 1 and 2 of the fair value hierarchy. The ASU also clarifies that fair value measurement disclosures should be presented for each asset and liability class, which is generally a subset of a line item in the statement of financial position. In the roll-forward of Level 3 activity, companies must present information on purchases, sales, issuances, and settlements on a gross basis rather than on a net basis. Companies should also provide information about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring instruments classified as either Level 2 or Level 3. In the first quarter of 2011, the Company adopted the requirement for gross presentation in the Level 3 roll-forward with prospective application. The remaining provisions were effective for the Company in the first quarter of 2010. Adoption of the ASU did not have a significant impact on the consolidated financial statements of the Company since it amends only the disclosure requirements for fair value measurements. ASU 2011-02, A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring, provides guidance clarifying under what circumstances a creditor should classify a restructured loan as a troubled debt restructuring or “TDR”. A loan is a TDR if both of the following exist: (1) a creditor has granted a concession to the debtor, and (2) the debtor is experiencing financial difficulties. The ASU clarifies that a creditor should consider all aspects of a restructuring when evaluating whether it has granted a concession, which include determining whether a debtor can obtain funds from another source at market rates and assessing the value of additional collateral and guarantees obtained at the time of restructuring. The ASU provides factors a creditor should consider when determining if a debtor is experiencing financial difficulties, such as probability of payment default and bankruptcy declarations. The Company adopted the new guidance in the third quarter of 2011 with retrospective application to January 1, 2011. Adoption of the ASU required expansion of the Company's disclosures surrounding TDRs. See Note 6, Loans and Allowance for Loan Losses. 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, 2011, all of the Company's securities were classified as available-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 accumulated other comprehensive loss, 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 using 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 gains (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 entity will be required to sell the debt security before recovery of its amortized cost basis, or (3) the entity 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 that it will be required to sell the debt security before recovery, the other-than-temporary 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 recovery, 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 securities 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 is 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 value as determined on an aggregated basis. Estimated fair value is determined on the basis of existing commitments or the current market value of similar loans. 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 of the loan, if applicable. Gains on the sale of loans held for sale are recorded as part 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 center 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 the collateral securing these loans. F ailure 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 requests) if such failure cannot be cured by the Company within the specified period following discovery. During 2011, 2010 and 2009, no loans were repurchased and no reimbursements for investor losses were made by the Company. Loans Loans are reported at their outstanding principal balances, net of any unearned income, charge-offs, and any deferred fees or costs on originated 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 interest 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 significant 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 collection. 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 determines 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 loan 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 component of the provision for loan losses. Impaired loans also included 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 conditions 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 management 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 allowance 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 received 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 subsequent 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 Loa n Bank of Atlanta). These securities are accounted for under the cost method 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 value 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. loan 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 maintain 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 determines the fair value of MSRs at the date the loan is transferred. 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 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. The amortization of MSRs is analyzed monthly and is adjusted to reflect changes in prepayment speeds, as well as other factors. MSRs are evaluated 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 reserve is established through a charge to earnings. The valuation reserve 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 FASB 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 enacted 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 o ther a ssets 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 occurred 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 gains or losses on available-for-sale securities. In accordance with ASC 740, 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 Company's policy to recognize interest and penalties related to income tax matters in income tax expense. The Company and its wholly-owned subsidiary file a consolidated income tax return. Fair Value Measurements FASB ASC 820, 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 measurement 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 Disclosures. Subsequent Events The Company has evaluated the effects of events or transactions through the date of this filing th at have occurred subsequent to December 31, 2011. The Company does not believe there are any material subsequent events that would require further recognition or disclosure, except as discussed in Note 22, Subsequent Events.
